Door node D includes the node 100 of the cover and the first hinge node 300a. The node 100 of the cover is connected with the possibility of rotation with the upper closing element 200, to provide the user the option of opening and closing of the holes h. The first hinge 300a connects the node 100 of the cover with the upper closing element 200. The front end of the node 100 of the cover may protrude more than the upper closing element 200, the node 100 of the cover remains closed for easy opening of node 100 caps.

The node 100 of the cover includes an upper frame 110 of the cover, the inner element 120 caps, transparent element 130, the lower frame 140 of the cover and the decorative panel 150.

The upper frame 110 of the cover forms the appearance of the upper part of the node 100 of the cover, and the bottom frame 140 of the cover forms the appearance of the lower part of the node 100 of the cover. The internal element 120 of the cover is provided between the upper frame 110 of the cover and the bottom frame 140 of the cover to increase the rigidity of the node 100 of the cover, thus preventing Defoe is the formation of the node 100 of the cover, and to install the transparent element 130.

The upper frame 110 of the cover and the bottom frame 140 of the cover are open in their Central part, thus linen can be seen from the outside. The internal element 120 caps formed on the periphery of the node 100 of the cover to surround and fix the transparent element 130.

The internal element of the cover may be made in the form of a single body. Also, there may be many internal elements of the cover. In accordance with the embodiment, for example, can be provided by four internal element 120 of the cover, as shown in Fig.6, each of the inner elements 120 caps is located near the corner of the node 100 caps for fixing the angle of the node 100 caps.

Internal elements 120 of the cover is located between the upper frame 110 of the cover and the bottom frame 140 of the cover and surround the transparent element 130. Thus, the internal elements 120 of the cover is provided between the transparent element 130 and the upper frame 110 of the cover. Internal elements 120 of the cover can have a proper tolerance corresponding to the shape of the transparent element 130, so transparent element 130 can be fixed without rocking.

For example, the internal elements 120 of the cover can be made of plastic molded body to have a slight elasticity. Transparent element 130, surrounded by vnutriryegional 120 caps, firmly planted in the upper frame 110 of the cover due to applied outside force, thereby locking the transparent element 130 without rocking. As a consequence, the node 100 of the cover may be increased.

Transparent element 130 is a window which is made of a transparent material to allow the user to see lingerie in the inner tank 35 of the washing machine W through the transparent element 130. In accordance with the embodiment of the transparent element 130 may be made of transparent plastic or reinforced glass, which provides sufficient strength relative to the external force or scratches.

The upper end of the decorative panel 150 is connected with the front end of the upper frame 110 of the cover, and the lower end of the decorative panel 150 is connected to the bottom frame 140 of the cover, thus forming a handle, which can keep the user for turning the node 100 of the cover. Decorative panel 150 may enhance the connection of the upper frame 110 of the cover and bottom of the frame 140 of the cover. Also, the decorative panel 150 prevents visibility from the outside of the joined part of the upper frame 110 of the cover and bottom of the frame 140 of the cover, thereby improving the aesthetic appearance of the node 100 caps.

The first hinge 300a connects the node 100 of the cover with the upper closing element 200 and reduces the closing speed of the node 100 of the cover h is given section, where the node 100 of the cover is closed.

The first hinge 300a includes an elastic element 330a and a Cam site that elastically deforms the elastic element 330a, when the node 100 of the cover is rotated, and converts the return force applied from the strain of the elastic element 330a, in the torque force.

Elastic element 330a may be made of different types of elements that are deformed when the node 100 of the cover is rotated, to generate an elastic force or return efforts. Elastic element 330a may be properly selected depending on characteristics such as place of installation or construction. In accordance with the embodiment of the elastic element can be a spring 330a, which is compressed when the node 100 of the cover is rotated.

The first hinge 300a may be provided in the node 100 of the cover or upper closing element 200. For example, when the upper closing element 200 may not provide sufficient space for the first articulated node 300a due to the holes h, the first hinge 300a may be provided in the node 100 caps.

The first hinge 300a may be connected to the node 100 caps by different designs. For example, in accordance with the embodiment of the first hinge 300a can be mounted on the inside is it the element 120 caps.

Door node D may further include a second hinge node 300b. The end node 100 cap connected to the upper closing element 200 through the first hinge node 300a and the other end node 100 cap connected to the upper closing element 200 through the second hinge node 300b.

The first hinge 300a generates a torque in the direction of opening of the node 100 of the cover at a given site where the node 100 of the cover is rotated. This torque provides the possibility of reducing the speed of closing of the node 100 of the cover when the node 100 of the cover is closed on a given plot, and provides the ability to easily open the node 100 caps with less effort when the node 100 of the lid is opened on the specified section.

The second hinge 300b is used to reduce the speed of rotation of the node 100 caps in a variety of ways, such as, for example, the application of oil pressure or table properties helical springs. In this embodiment, the second hinge uses the application of the oil pressure. However, the present invention is not limited to them. For example, various known types of hinge assemblies can be used to reduce the speed of rotation.

In the present embodiment, the second hinge 300b filled with fluid medium and includes the filing blade (not shown), which is immersed in the fluid and is rotated in a functional interaction with the host 100 caps. When the node 100 of the cover is rotated, the resistance, such as resistance or the pressure of the applied fluid medium to the rotating blades, thereby reducing the speed of rotation of the node 100 caps.

When the node 100 of the cover is rotated not only close, but also turns to open, the resistance of the second hinge node 300b causes the specified torque against rotation of the node 100 caps.

From the point of view of a stable rotation of the node 100 of the cover, the second hinge 300b operates as a hydraulic shock absorber to improve the sense of control when the node 100 of the cover is rotated.

In accordance with the embodiment of the first hinge node 300a and the second hinge 300b can be aligned with the axis of rotation of the node 100 caps.

Cam site contained in the first hinge node 300a, converts the rotational movement of the node 100 caps in the progressive movement, which provides the possibility of elastic deformation of the elastic element 330a.

Referring to Fig.7 and 8, the first hinge 300a includes a housing 310a of the first pivot point, which is inserted into the internal element 120 of the cover and contains a Cam site, and closing ale is NT 390 cases of the first pivot point, which is connected to the housing 310a of the first pivot point by means of a connecting element, such as a screw or bolt 399.

The connecting arms 314a and 392a protrude from the housing 310a of the first pivot point and the closing element 390 cases of the first pivot point, respectively. The connecting arms 314a and 392a are connected to each other and, in addition, is connected to the upper frame 110 of the cover by means of a connecting element, such as a screw.

Housing 310a of the first strut includes a protruding and a lower surface 316 that is connected to the closing element 390 cases of the first pivot point, and the protrusions 311a, 312a and 313a, which prevent idle rotation of the first hinge node 300a in the internal element 120 caps. The internal element 120 caps includes slots into which you insert the protrusions 311a, 312a and 313a. The first hinge 300a protected from the idle rotation in the inner element 120 caps by inserting protrusions 311a, 312a and 313a in the slots.

Fasteners, such as screws or bolts, are connected through the upper frame 110 cap with the connecting holes 315a and 393a provided in the connecting levers 314a and 392a, and the first hinge node 300a is inserted into the inner element 120 of the cover, thus the node 100 of the cover can be rotated in the functional interaction with first the m swivel node 300a.

Cam site of the first hinge node 300a includes a rotating Cam 380a, functionally interacts with the host 100 caps, and reciprocating movement of the Cam 360a, which engages with the rotating Cam 380a to make a reciprocating motion along the shaft 350a. The shaft 350a is connected to the bracket 240 of the shaft, provided in the upper closing element 200.

The bracket 240 of the shaft limits the rotation of the shaft 350a. To this end, the shaft 350a includes a groove 351a along the longitudinal direction, and the bracket 240 of the shaft includes a bearing hole 243 to the shaft, which has a cross-sectional shape corresponding to the cross-sectional shape of the shaft 350a having a groove 351a.

The shape of the reciprocating movement of the Cam 360a conforms to the shape of the rotating Cam 380a. Reciprocating movement of the Cam 360a and the rotating Cam 380a made so as to be inclined along the circumferential direction so that the height of the plot, where the reciprocating movement of the Cam 360a and the rotating Cam 380a contact with each other, changes. In design, in which the reciprocating movement of the Cam 360a and the rotating Cam 380a coupled with each other, the surface of the rotating Cam 380a, which is flanged adjacent to the reciprocating movement of the fist 360a, converts rotational movement of the rotating Cam 380a in the forward movement, so as to allow reciprocating movement of the fist 360a to make a reciprocating motion. This surface is further defined as "the surface of the m transformation. Profile of inclination of the surface m conversion, if viewed from the side surface, is defined as "the line's transformation.

Moreover, the surface of the reciprocating movement of the Cam 360a adjacent to the surface of the m transformation rotating the Cam 380a, allows reciprocating motion of the fist 360a to perform the reciprocating movement along the shaft 350a for application of force to the surface of the m transformation. This surface is defined as "working surface m'".

Although this embodiment has been described that the rotating Cam 380a and reciprocating movement of the Cam 360a have the same shape, i.e. the surface profile of the m transformation rotating the Cam 380a is identical to the profile of the working surface m' reciprocating movement of the Cam 360a, the present invention is not limited to this. For example, the shape of the surface conversion and the working surface does not matter, dormancy is a surface conversion is formed on the rotating Cam 380a, and corresponding to the surface profile of the transformation of the working surface is formed on the reciprocating movement of the Cam 360a so that reciprocating movement of the Cam 360a can make reciprocating movement at a certain distance, when the rotating Cam 380a rotates.

Similarly, the working surface may be formed on the reciprocating movement of the Cam 360a, and the corresponding profile of the working surface surface conversion may be formed on the rotating Cam 380a to convert the force applied from the working surface of the reciprocating movement of the Cam 360a, so that the rotating Cam 380a can be rotated.

Now will be described an implementation option, in which the surface m transformation rotating the Cam 380a and the working surface m' reciprocating movement of the Cam 360a made identical to each other. The description will be mainly focused on the surface of the m transformation and lines s converting formed on the rotating Cam 380a.

When the node 100 of the cover is rotated, the surface m transformation rotating the Cam 380a slides with rotation along the working surface m' with arausio reciprocating motion of the Cam 360a and subjected to efforts applied from the working surface m' reciprocating movement of the Cam 360a. The efforts towards changing the inclination of the surface m transformations to generate the torque.

Travel distance reciprocating movement of the Cam 360a varies with the rotation angle of the rotating Cam 380a. The inclination of the surface m transformation can be mounted reasons, for example, the distance to move the reciprocating movement of the Cam 360a. Since the distance of movement of reciprocating movement of the Cam 360a is equal to the length of the spring 330a in a compressed state, we can say that the slope of the surface m transformation is closely related to the torque applied to the first hinge node 300a.

In this embodiment, the Cam node includes a shaft 350a, a rotating Cam 380a and reciprocating movement of the Cam 360a. Reciprocating movement of the Cam 360a begins to perform the reciprocating movement along the shaft 350a thanks ottalkivayuschey the force applied from the rotating Cam 380a, when the node 100 of the cover is rotated. In this situation, as described above, the elastic element 330a, connected with the shaft 350a elastically deformed. More t the th, return force of the deformed elastic element 330a is converted into torque force through the Cam site, thereby creating a torque.

Therefore, when the node 100 of the cover is rotated, the Cam node converts the rotational motion of the rotating Cam 380a in the forward movement of the reciprocating movement of the Cam 360a and Vice versa through the interaction between the rotating Cam 380a and reciprocating movement of the Cam 360a.

The first hinge 300a may further include a washer 320a placed between the spring 330a and the housing 310a of the first pivot point, the sleeve 340a, connected with the shaft 350a, and the sleeve 370a inserted into the sealing element 390 cases of the first hinge unit for supporting the shaft 350a.

When rotating the rotating Cam 380a, reciprocating movement of the Cam 360a performs a linear reciprocating motion, while placed on the shaft 350a, and spring 330a is stretched or compressed reciprocating movement of the Cam 360a. The shaft 350a includes a stepped section 352a, which limits the distance that reciprocating movement of the Cam 360a.

Figa is a view illustrating a construction in which the bracket shaft connected with the lower surface of the upper closing element, the fixing shaft, connected with the second hinge node so that the shaft is not rotating. Figv is an enlarged view of part A shown in figa. Figure 10 is a perspective view illustrating the bracket of the shaft shown in figa.

Referring to figa, 9B and 10, the bracket 240 of the shaft attached to the bottom surface of the upper closing element 200 to the support shaft 350B water connected with the second hinge node 300b. To support the shaft 350a of the first hinge node 300a bracket shaft 240 may also be provided on the side where you installed the first hinge node 300a.

Although figa, 9B and 10 show the bracket 240 of the shaft to support the shaft 350B water connected with the second hinge node 300b, the same design can also be used to support the shaft 350a of the first hinge node 300a. Now will be described an implementation option, in which the bracket 240 of the shaft supports the shaft 350a of the first hinge node 300a.

The bracket 240 of the shaft supports the shaft 350a of the first hinge node 300a, at least in two points. For example, the bracket 240 of the shaft includes a first bearing 241 and the second bearing 242, which are spaced from each other to support the shaft 350a two points.

The first bearing 241 and the second bearing 242 includes a reference hole 243 to the shaft that supports the shaft 350a. The reference hole 243 to the shaft, the first bearing 241 mo is et to have the same shape, as the form of the reference hole 243 to the second support shaft 242.

Essentially, the shaft 350a is supported by a bracket 240 of the shaft at two points. Therefore, even if force is applied to the shaft 350a, when the node 100 of the cover is rotated, the shaft 350a aligned on an axis with the two support holes 243 of the shaft. Thus, the shaft 350a can stably be maintained without rocking, thus significantly improving the sense of the management node 100 caps.

The shaft 350a includes a groove 351a formed essentially flat milling shaft 350a along the axial direction to prevent rotation of the shaft 350a, when it is inserted into the support hole 243 to the shaft. The reference hole 243 of the shaft has a shape corresponding to the shape of the shaft 350a. However, the present invention is not limited to this. Any designs can be used by the average person skilled in the art to prevent rotation of the shaft 350a.

The sleeve 246 is inserted into the bracket 240 of the shaft. The sleeve 246 is a shock-absorbing element, which is placed between the shaft 350a and bracket 240 of the shaft. The sleeve 246 is made of a slightly elastic material, such as plastic, to prevent wear of the shaft 350a and bracket 240 of the shaft due to friction between the shaft 350a and bracket 240 of the shaft. The bracket 240 of the shaft includes a connection hole 245 to which the tool is and the sleeve 246.

11 is a side view illustrating the rotational movement of the node cover. Fig is a view illustrating the profile obtained by scanning a rotating Cam of the first pivot point. Fig is a view illustrating the mutual position between the reciprocating movement of the Cam and rotating Cam when the node cover figure 11 is located at point A. Fig is a view illustrating the mutual position between the reciprocating movement of the Cam and rotating Cam when the node cover figure 11 is located between points B and position D. Fig is a view illustrating the mutual position between the reciprocating movement of the Cam and rotating Cam when the node cover figure 11 is located at the point D.

Now will be described the process of opening the node 100 caps.

Referring to 11, the first hinge 300a generates a torque in the direction of opening of the node 100 of the cover when the node 100 of the cover is rotated between the positions B and D, so the user can open the node 100 caps with less effort. Rotating the Cam 380a first hinge node 300a has the profile shown in Fig.

When the point P reciprocating movement of the Cam 360 (citing Fig-15) is located in the area between points Pb and Pd, reciprocating movement of the Cam 360a applies force to a rotary fist 380a in the axial direction due to the returning force of the compressed spring 330a, and the applied force is converted into torque force through the surface m conversion, obliquely formed on the rotating Cam 380a. Therefore, torque is generated in the direction to open the node 100 of the cover, so the user can open the node 100 caps with less effort.

The resulting torque T applied to the node 100 cap equal to the amount of torque Tg, created by the weight of the node 100 caps, torque, Ts, created the first hinge node 300a and torque Td, created the second hinge node 300b. When the node 100 of the cover is located on the first segment between points B and C, the torque Ts is applied in the direction of opening of the node 100 caps, but the resulting torque T is still applied in the closing direction of the node 100 of the cover. I.e, T=Tg-Ts-Td>0. "T>0" indicates that the torque is applied in the closing direction of the node 100 caps, and T<0" indicates that the torque is applied in the direction of opening of the node 100 of the cover. Here, "Tg", "Ts" and "Td" represents the value of the torques, "+" means that the torque of prikladyvat is carried out in the closing direction of the node 100 of the cover, and "-" means that the torque is applied in the direction of opening of the node 100 caps.

When the node 100 of the cover is located on the second section between points C and D, T=Tg-Ts-Td<0. Thus, the node 100 of the cover can be opened without external force.

Specifically, as T>0 on the first segment between points B and C, the user is required more force to open the node 100 of the cover. T<0 after passing through point C. Therefore, the second section between points C and D, the node 100 of the cover can be rotated automatically to point D without requiring additional user effort. I.e. on the first segment relative to the point C, the node 100 of the cover is automatically closed, and, thus, to open the node 100 caps is a necessary additional effort. In this case, however, the node 100 of the lid can be opened with less effort thanks to the torque Ts applied in the direction of opening of the node 100 of the cover. And the node 100 of the cover can automatically be opened without additional effort on the second section between points C and D.

Now will be described the process of closing node 100 caps.

The Assembly 100 cap stays open in the point D. Then, the user applies force to the node 100 of the cover so that the node 100 of the cover is located at point C. After passage of C T>0, and, thus, the node 10 of the cover automatically turns without additional effort in the closing direction of the node 100 of the cover. On the first segment between points C and B torques Ts and Td are applied first hinge node 300a and the second hinge node 300b in the direction of opening of the node 100 of the cover. Therefore, the speed of rotation of the node 100 of the cover is reduced to prevent excessive blow node 100 of the cover about the upper closing element 200.

After passing the node 100 cap point B, i.e. when the node 100 of the cover is located on the third section between points B and A, the point P is located on a plot of S1, which is tilted in the opposite direction relative to the area S2, and thus, the torque Ts is applied in the closing direction of the node 100 of the cover, thereby closing the node 100 of the cover more securely (T>0).

Thus, when the node 100 of the cover is closed on the first segment between C and B, the speed of rotation of the node 100 caps reduced torques Ts and Td, which are applied in the direction of opening of the node 100 of the cover. In the third section between B and A torque Ts is applied in the closing direction of the node 100 of the cover due to the slope of the site S1, and thus, the closing speed is increased. Therefore, the node 100 of the cover can be securely closed. In this case, since the opening angle at point B, where you change the direction of action of the torque Ts applied to the node 100 caps (hereinafter the "opening angle" is azyvaetsja angle, measured in the direction of opening of the node 100 of the cover. The opening angle is assumed to be 0 degrees when the node 100 caps closed), represents the angle at which the speed of rotation of the node 100 of the cover begins to increase, the opening angle will now be defined as the "base angle of the accelerated closing". Although the base angle of the accelerated closing is set to 10 degrees, the present invention is not limited to this.

In the washing machine W according to the embodiment of the present invention, the node 100 of the cover is automatically opened or closed relative to point C. further, the opening angle when the node 100 of the cover is located at the point C, is called the "base angle automatic opening" from the point of view of the opening process of the node 100 of the cover and the base angle automatic closing" from the point of view of the process of closing node 100 caps.

Although the base angle of the automatic opening/closing is 80 degrees, as shown in figure 11, the present invention is not limited to this. For example, the base angle of the automatic opening/closing may include various angles, such as the opening angle not greater than 90 degrees.

The base angle of the accelerated closing and/or the base angle of the automatic opening/closing can be properly specified reasons, choose from the VA use and reliability. For example, the weight of the node 100 of the cover and/or torque capacity of the first hinge node 300a and the second hinge node 300b can be optionally designed. Here, "torque capacity" is defined as the range of torques that can be created first hinge node 300a or the second hinge node 300b, i.e. the range between the maximum torque and minimum torque.

Torques generated by the first hinge node 300a may vary in a given range depending on the length of the elastic element in a compressed state, which changes when the node 100 of the cover is rotated. Torque generated by the second hinge node 300b, can be adjusted within a given range depending on the compressibility of the fluid, which changes when the node 100 of the cover is rotated.

There may be different relationships between the torque capacity of the first hinge node 300a and torque capacity of the second hinge node 300b.

When the ratio of the torque capacity of the first hinge node 300a to the torque capacity of the second hinge node 300b is 8:2, Ts becomes relatively larger than Td. Therefore, the second area on which the node 100, the lid opens automatically, can have a large range.

For example, when the ratio is 8:2, the ate 100 caps can automatically open, when the opening angle of the node 100 of the cover reaches 80 degrees.

When the ratio of the torque capacity of the first hinge node 300a to the torque capacity of the second hinge node 300b is 7:3, the difference between Ts and Td is relatively small compared to the case when the ratio is 8:2. Therefore, the second section is narrowed, and the first section is expanded. For example, the node 100 of the cover automatically opens when the opening angle is 85 or more degrees, and automatically closed when the opening angle is 85 or less degrees.

Similarly, when the ratio of the torque capacity of the first hinge node 300a to the torque capacity of the second hinge node 300b is 6:4, the second segment is additionally narrowed, and the first section is expanded compared with the case when the ratio is 7:3. For example, the node 100 of the cover automatically opens when the opening angle is 90 or more degrees, and automatically closed when the opening angle is 90 or less degrees.

The ranges of the first section and the second section, dependent torque capacity, have been described, assuming that the mass of the node 100 caps is a constant. However, since the mass of the node 100 of the cover varies, torque Tg is generated by the weight of the node 100 caps, is changing. Sledovatel is, the first section and the second section are also changing. As a result, even when the ratio is 7:3 or 6:4, the node 100 caps may work similarly to the case when the ratio is 8:2, by changing the mass of the node 100 caps.

The first hinge node 300a and the second hinge 300b can be performed so that the range torque capacity of the first hinge node 300a and torque capacity of the second hinge node 300b has a proper value depending on the weight of the node 100 of the cover. By doing this, the node 100 of the cover can automatically open or close the specified first and second sections.

For example, assuming that the node 100 of the cover is automatically closed when the opening angle is from 0 to 80 degrees, and automatically opens when the opening angle is between 80 and 110 degrees, when the mass of the node 100 caps is W1, the ratio of the torque capacity of the first hinge node 300a to the torque capacity of the second hinge node 300b may be provided is equal to 6:4. If the mass of the node 100 of the cover is changed from W1 to W2 greater than W1, the torque produced by the weight of the node 100 of the cover increases. Therefore, for automatic opening of the node 100 of the cover at a given second plot it is necessary to increase the torque capacity of the first hinge node 300a. In this case, against whom their torque capacity of the first hinge node 300a to the torque capacity of the second hinge node 300b may be 7:3 or 8:2.

Thus, the range of the first and the second section may be determined depending on the torque capacity of the first hinge node 300a and the second hinge node 300b and/or weight of the node 100 of the cover. And the node 100 of the cover may be adapted for automatic opening/closing at predetermined first and second areas through the implementation of the first hinge node 300a and the second hinge node 300b so that the torque capacity of the first hinge node 300a and torque capacity of the second hinge node 300b has a proper value depending on the weight of the node 100 caps.

The first hinge 300a may be adapted for automatic closing of the node 100 of the cover when the opening angle is not more than 60 degrees, to improve usability. For example, the first portion may have an opening angle of 60-80 degrees.

Moreover, the second section may have an opening angle of 80-90 degrees, thus the node 100 of the cover can automatically open, even when the opening angle is slightly less than 90 degrees.

The base angle of the automatic opening/closing described above in conjunction with 11 represents the angle of the node 100 of the cover, in which the node 100 of the cover is located at the point C. for Example, the base angle of the automatic opening/closing the can with the presentation, essentially, 80 degrees. This corresponds to a situation in which P is located in on Pc Fig.

Torque Ts, created by the first hinge node 300a and torque Td, the generated second hinge node 300b may be selected as an appropriate value, taking into account torque Tg is generated by the weight of the node 100 of the cover. For example, the Ts may be relatively larger than Td. Moreover, between Ts and Td may be appropriate ratio so that the node 100 of the cover can automatically open on the second section between C and D. for Example, in accordance with the embodiment the ratio Ts:Td can be, essentially, 8:2.

In the profile shown in Fig, turning node 100 caps is accelerated at site S1 for more reliable closing of the node 100 of the cover. Further, the area S1 is called "managing area accelerated closure". The slope of the plot of S1 is called "managing tilt accelerated closing". The speed of rotation of the node 100 of the cover when the node 100 of the cover is rotated to cover reduced at site S2. Further, the area S2 is called "managing land to reduce the speed of closing". The slope of the plot of S2 is called "managing inclination to reduce the speed of closing". At site S3, the node 100, the lid opens automatically, without additional effort when the node 100 chrysopolitissa for opening. Further, the area S3 is "part of the automatic opening". The slope of the terrain S3 is called "managing tilt automatic opening".

In this embodiment, the line's transformation rotating the Cam 380a was described by a straight line. However, the present invention is not limited to this. The line's conversion may be a curved line. Moreover, the surface m of the transformation can be made to have different slopes at site S2 in such a way that the degree of reduction of the closing rate of the node 100 of the cover is changed, or the surface m of the transformation can be made to have different slopes at site S3 so that the opening speed of the node 100 cover changes on the site automatically open the node 100 caps.

Moreover, may be provided for rotating the Cam 380a, not containing section S1. In this case, when the node 100 of the cover has an angle equal to or smaller than the reference angle automatic opening, the node 100 of the cover can be controlled so that the closing speed is reduced until the complete closing of the node 100 of the cover. However, in all cases, the node 100 of the cover can automatically open or close without the efforts of the user relative to the base angle of the automatic opening/closing. Moreover, the node 10 of the cover can be controlled so the closing speed is reduced at a certain podcastle site closing or on the plot.

Fig is a graph illustrating the torque generated in accordance with the rotation angle of the node cover. On Fig shows Tg and Ts without considering the influence of the second hinge node 300b. However, even if torque Td, the generated second hinge node 300b, were taken into account, the shape of the graph would be essentially similar to the form shown in Fig.

Referring to 11 and 16, when the node 100 of the lid slowly opened and, accordingly, the opening angle increases, torque Tg is generated by the weight of the node 100 of the cover, and torque Ts, created by the first hinge node 300a, attached to the node 100 of the cover. At the site, where the opening angle is approximately from 50 to 90 degrees, Tg is applied in the closing direction of the node 100 of the lid, and Ts is applied in the direction of opening of the node 100 of the cover. At the point where the opening angle is 80 degrees, Tg-Ts is -7,1 kgf·see

In accordance with the embodiment, assuming that the node 100 of the cover is rotated in the closing direction of the node 100 of the cover at an angle equal to or less than about 80 degrees, and rotates in the direction of opening of the node 100 of the cover at an angle equal to or greater than about 80 degrees, resulting in amausi moment applied in the closing direction, at an angle equal to or less than 80 degrees, is reduced to a minimum, and the resulting torque applied in the direction of the opening, at an angle equal to or larger than 80 degrees, all the way up, thus closing speed of the node 100 of the cover is reduced when the node 100 of the cover is rotated for closing and opening speed of the node 100 of the cover is increased when the node 100 of the cover is rotated to open.

With this purpose on the side of the node 100 of the cover may be provided in the second hinge 300b, and the second hinge 300b may have a proper torque ability to perform the above conditions. As an example, only when Td is applied in the direction of opening of the node 100 of the cover at an angle of opening 80 degrees or applied in the closing direction of the node 100 caps with a value less than the 7.1 kgf·cm, the total torque T applied to the node 100 caps, becomes negative, thus the node 100 of the cover can automatically open at an angle of 80 degrees or more.

Therefore, to create torque, sufficient to meet the conditions, you may need a second hinge 300b in accordance with the embodiment, which can automatically open or close the node 100 of the cover relative activities is but a given angle (above the base angle of the automatic opening/closing, for example, 80 degrees in this embodiment).

Fig is a perspective view with exploded parts illustrating the first hinge 300a' in accordance with another embodiment of the present invention. The description of the same or similar structures as in the first hinge node 300a described in connection with figure 1-16, will not be repeated.

Referring to Fig, the first hinge 300a' includes a Cam site that has a different design than the first pivot node 300a. Cam site includes a locking Cam 380a', recorded in such a way that its rotation is limited by the shaft 350a', Cam 360a' conversion, which is coupled with the locking Cam 380a', for converting rotary motion into reciprocating motion, and a spring that is compressed or stretched, the reciprocating motion of the Cam 360a' conversion. In accordance with the embodiment to generate sufficient elastic efforts may include two spring 331a' and 330a'. Cam 360a' conversion includes multiple locking tabs 361a' on the outer peripheral surface and is inserted into the guide groove 317a'provided on the inner peripheral surface of the housing 310a' first pivot point. As the Cam 360a' the transformation of the project is rotated together with the first hinge node 300a', Cam 360a' conversion is directed to make a reciprocating motion along the guide groove 317a'. Spring 331a' and 330a' is placed between the Cam 360a' conversion and the housing 310a' first pivot point.

The shaft 350a' includes a groove 351a' so that its rotation is limited when connected to a bracket 240 of the shaft. The locking Cam 380a' includes a polygonal protruding and depressed section 382a' on the plot, which is connected with the connecting end 352a' shaft 350a'. The connecting part (not shown) made on the connecting end 352a' shaft 350a'to have a shape corresponding to the shape and serving lower part 382a', thus locking the Cam 380a' does not rotate.

Elements 310a', 311a', 312a', 313a', 314a', 315a', 316', 390a', 392a', 393a' and 399a' have essentially the same structure as the elements 310a, 311a, 312a, 313a, 314a, 315a, 316, 390a, 392a, 393a and 399a, respectively, and, therefore, description will not be repeated.

Now will be described the operation of the hinged node 300a'.

When rotated, the node 100 of the cover, respectively, rotates the Cam 360a' conversion. And Cam 360a' conversion also makes a reciprocating motion due to the shape of the ends 381a' and 362a' locking Cam 380a' and Cam 360a' conversion.

When the node 100 of the cover is rotated to the closing, the Cam 360a' conversion is of gradually slides into the housing 310a' first pivot point for the compression spring 330a' and 331a'. On the contrary, when the node 100 of the cover is rotated to open, the Cam 360a' conversion gradually slides out of the housing 310a' to restore the original shape of the compressed spring 330a' and 331a'.

In the previous embodiment, torque is applied to the node 100 of the cover by means of a Cam site that includes a rotating Cam 380a, rotating together with the node 100 caps, reciprocating movement of the Cam 360a, which is connected with the shaft 350a limiting the rotation of the way and makes a reciprocating motion when rotating the Cam 380a is rotated, and spring 330a, which is compressed and stretched reciprocating movement of the Cam 360a. On the contrary, in this embodiment, torque is applied to the node 100 of the cover by means of a Cam site, which includes a locking Cam 380a', which rotation is limited, the Cam 360a' transformation, which rotates together with the node 100 of the cover and makes a reciprocating motion due to the force applied from the locking Cam 380a', and spring 330a' and 331a', which are compressed and stretched Cam 360a' conversion.

In particular, in this embodiment, two springs, for example, the first and second spring 330a' and 331a', are not, as in preaches the current embodiment, the first and second spring 330a' and 331a' differ from each other in length and diameter. The second spring 331a' has a small diameter and length compared with the first spring 330a' for insertion into the first spring 330a'. In this design, double spring, only the first spring 330a' is compressed, and the closing speed of the node 100 cover reduced at the site when the node 100 of the cover is closed, and then, after passing through the plot, the second spring 331a' is compressed together with the first spring 330a' to further reduce the speed of the closing of the node 100 caps.

The torque produced by the weight of the node 100 caps, is incremented when the node 100 of the cover is closed, and thus, the closing speed can sharply increase. To reduce such a sharp increase in the speed of the second closing spring 331a' are additionally provided in the first spring 330a'. Specifically, when the first spring 330a' gradually shrinks to reach the end of the second spring 331a' (for example, when the opening angle is 20 degrees), the first and second spring 330a' and 331a' are compressed together to effectively reduce the speed of the closing of the node 100 caps.

The host 100 caps after the first hinge 300a' attached to the node 100 caps, essentially, is the same or similar to that described in the previous embodiment, and p is this, description will not be repeated.
