The invention relates to anti-skid device for the wheels of the transport device with the fastening device, which has at least fixed in one place on the wheel of the transport device of the tension element and the driven manually and acting on the tension element of the handle, while the handle is additionally made in the form of an ergonomic gripping element to remove the anti-skid device with the wheels of the transport device and to compress the anti-skid device to the wheel.

Known for the design of the anti-skid device includes a mounting device by which the anti-skid device can be slipped over the wheel of the transport device, in most cases on the wheel rim. The first such anti-skid devices have been proposed many years ago, as US 2601882 declared in 1949, this device is snow covering the tread of the wheels of the transport device increases the coupling elements are elongated in the radial direction by means of the clamping bolt. Pinch bolt indirectly through the coupling elements is fixed in its radial position relative to the wheels of the transport device.

In addition, a special, but not exclusive interest for the present invention device is istwa snow, that first when standing vehicle pre-mounted manually on the wheel of the vehicle, and then start driving yourself completely tightened. Such anti-skid device has also long been known, for example, from US 2730156. This anti-skid device is elastically deformable in the axial direction of the disk with ribs, which on its periphery carries the coupling elements, in US 2739156 - running belt with spikes, and in its middle by means of fasteners screwed directly to the vehicle's wheel.

When mounting the coupling elements in the zone of the support surface of the tire cannot be put between the protector and the ground, so that in this place the coupling elements are located next to the protector, and the disc is resiliently deflected in the axial direction. Automatic residual installation is carried out when at the beginning of the movement of the coupling elements in a reverse warp drive is coming to the rest of the running surface of the tire.

This basic principle samanalawewa anti-skid device for years was improved in many details, as shown in AT-C-288178, CH-C-509890, DE-A-2721969, WO-A-84/04071, DE-A-3142489, DE-A-3545529, WO-A-2004/039611, WO-A-2008/029424 and listed in the "Catalogue of snow chains 2008" by Thule, Inc. snow chains K-SUMMIT.

Also EP-A-0264343, ER-IN-298906, ER-IN-37646, EP-IN-376427, ER-IN-376428, ER-IN-460782 and ER-IN-911193 and listed in the directory ChainsAtTraction 2008/2009" called CENTRAX circuit of the applicant relate to samanalawewa snow chains.

The known anti-skid device, which can automatically perform residual installation, tensioning elements in the form of springs or non-elastic traction means, such as ropes or tapes. Tension means are used in these anti-skid devices to create tension force required for automatic residual installation. The tension is created manually by the fact that the user pre-installation leads to an action exerted on the tension element handle. This is solved in the known devices of snow in parts in different ways:

So, for example, as an arm in EP-B-460782 put to use the crank, in EP-B-0376428 and WO-A-2004/039611 - hinged lever, in EP-B-376426 - button traction and snow chains K-SUMMIT - ratchet lever. As the tension elements are known having a spring force structural elements, such as elastomeric or wire spring, or inelastic structural elements, such as wires, screws, straps or tape. In the first, the tension for automatic residual installation is created by direct deformation of the structural element by putting in action the e arm. In the latter, by means of a lever and a tension element indirectly deforms the spring element; as springs can serve in this case the retaining shoulders with which tightened the coupling elements.

In WO-A-2008/029424 the tension element, the cable prior to installation pull manually by overcoming the spring force and fix. Then mount the anti-skid device, and then release the tension element, so that the tensile force can provide automatic residual installation. Auxiliary handle is used to adjust the retaining shoulders for bonding elements in the radial direction for the harmonization of anti-skid devices with different diameters of the tires.

In addition, in EP 2050592 A1 shows the anti-skid device with the retaining shoulders that you can pull through is formed on the rotary holder spiral channels. In EP 0352874 A2 shows the anti-skid device with rotary button, which in cooperation with the lever pulls on the tension elements. In WO 03/011618 A1 describes a device with anti-skid located on the Central wheel of the vehicle by the holder of four formed wire clips holding the shoulders, and the branch tension goes with disabilities to stretch richguy WO 91/03383 known As the anti-skid device, which has retaining arms is made in the form of a toothed rail ends, which are placed in centrally located on the vehicle's wheel holder. In the US 6915825 B1 shows the anti-skid device with a running network, which is kept by means of located concentric with the wheel axis of the vehicle tensioning device while connected to a running chain tension cables wound on located on the Central wheel of the vehicle, the tension pulley, which can be powered by using the handle.

Although, as follows from the above prior art device, anti-skid attachment device and the tensioning element is greatly improved relative ease of use compared to the original device is still, as before, preferably simpler, without the use of tools the service during installation and dismantling.

In line with this, the basis of the invention is to improve the known devices of the skid so that it additionally simplifies the handling. This task is solved according to the invention, the anti-skid device specified at the beginning of the view that the holding fixture includes made with the possibility of the drive arm winding device designed on the I winding tension element.

Thus, in comparison with the previously known anti-skid devices, the handle serves not only to actuate the tensioning element, but also on the basis of its ergonomic run as a gripping element for removing and cuddling anti-skid device. Thus, the solution according to the invention enables actuation of the tension element with one hand during mounting by pressing or, respectively, during the removal when removing, without having to remove the hands from the handle.

The solution according to the invention, can be further improved by several independent from each other embodiments. A brief description of these embodiments and related benefits listed below.

So, in the first preferred embodiment of an ergonomic execution of the gripping element can make a more comfortable grip on the anti-skid device during installation, when the arm is directed in the axial direction from the vehicle wheels push the surface. Push the surface can be performed, in particular, essentially smooth, i.e. without interfering protrusions or grooves. This push surface provides a comfortable compression arm when assembling to the bus. Smooth you shall olnine pressure surface prevents vesania edges and corners in the palm of his hand. The magnitude of the pressure surface may correspond, in particular, about the size of an average palm.

Removing the anti-skid device with the wheels of the vehicle can be simplified due to the ergonomic traction surface on the handle. Traction surface may be positioned in the assembled condition, the wheel of the vehicle, and thereby the user's fingers when tandem movement may well rely on the handle. In particular, the traction surface may be formed of at least one gripping depression and/or depression for fingers with the purpose of providing to the user a pleasant feeling.

Ergonomic execution of the handle is provided, in particular, when executing it in the form of a knob or mushroom. So, arm in assembled condition can be geboorte from the wheels of the vehicle, so the more narrow area of the arm rests on the side of the wheels of the vehicle, and the extension of the knob facing the user. This form also provides favorable from the point of view of ergonomics execution for the application of traction and pressure force the hand of the user during installation and dismantling of the anti-skid device.

In addition, the anti-skid device can be driven or, meet the but in effect, in particular, self-locking tensioning mechanism for tensioning element. In this implementation preferably, if the handle contains driven hand made with the possibility of influence on the tension mechanism deblocare switch, so that the tensioning mechanism can be stretched and weakened by the user without removing the hands from the handle.

Deblocare switch may be in the form of a push button or switch in the area of the pressure surface. However, to use applied by the user when removing the unit anti-skid traction synergistically to release tension mechanism, the handle itself may preferably be formed deblocare switch.

According to another preferred variant the execution of the tension element can contain the traction means, which is performed with the fixing of the at least one wheel of the vehicle and fastening at least one other place on the anti-skid device. Such traction means can be inelastic or elastic bands, straps, cables or chains or combinations thereof. Of course, you can also use other wound body as a tensioning element. Due to the winding tension element is Rostam way to create a tension force, which holds the anti-skid device on the wheel of the vehicle and/or automatically pulls the anti-skid device for a wheel of the vehicle at the beginning of the movement.

For actuating the tensioning mechanism and, in particular, the winding device is structurally simple way, the arm can be made to rotate, for example, in the form of a rotary button.

To enable correct execution using arm all be performed when servicing the device, anti-skid action at one time in another preferred embodiment it may be provided that the handle is directed with the ability to move in two different, preferably perpendicular to each other enforcement areas. One Executive direction provides the ability to actuate the tensioning mechanism, and the other Executive direction provides the opportunity to release tension mechanism. As mentioned above, the Executive direction for actuating the tensioning mechanism may be a rotary movement in one plane. Executive direction to release the tension mechanism may be preferably against the action prog is authorized strength, perpendicular to the pivoting plane and preferably directed from the tires of the vehicle.

To indicate to the user achieve with prior installation required for automatic residual mounting tension force in the handle can be integrated indicator element, which is made with the possibility of transfer exceeds a given exerted on the tension element, the tension force from the neutral position indication. In the position of the display may be visible warning marking indicator element, while in the neutral position it is closed.

According to another preferred variant implementation, the handle may have an indicator element, which is made movable, depending on the availability in the tension element, the tension force. This option execution provides for the filing of the user by moving specify that on the basis of the actuation arm created at least necessary for reliable automatic residual installation labor tension, and thereby successfully completed pre-installation. Due to this can be reduced the risk of improper execution, in particular, is only a partial pre-Assembly, in which the anti-skid device sits only obodno on the wheel of the vehicle. For example, characterized by a color signal warning the item can remain visible until it reaches the working force of tension in the tension element.

Finally, preferably, when the handle is in the radial direction of the anti-skid device in the middle, when device mounted on the skid preferably coaxially with the wheel or wheel hub of the vehicle. When this execution is possible by pressing or removing the anti-skid device to enter with arms symmetrically forces in the anti-skid device, which provides a uniform thrust and withdrawal. In addition, due to this you can send a tension element in the middle and also coaxially relative to the wheels of the vehicle in the direction of the wheels of the vehicle. This provides a structurally simple solution is relatively automatically generated during operation of the anti-skid wheel of a vehicle through an anti-skid device, i.e. the relative rotation of the anti-skid device relative bus.

Below is the example of explanation of the invention on the basis of various embodiments with reference to the accompanying drawings, while different in both versions follow the signs can be replaced independently from each other, if the invention in practice has no value associated with the corresponding characteristic advantage.

The drawings schematically:

figure 2 - section of option execution arm in isometric projection;

figure 3 - section handle, according to figure 2, in a partially-transparent image, in isometric projection;

figure 4 - section of another embodiment execution of the handle in isometric projection.

Here is the description of the anti-skid device 1 according to the invention, such as snow chains, with reference to figure 1. Figure 1 wheel 1' vehicles for simplicity shown only schematically.

The anti-skid device 1 has increasing traction elements 2, which in assembled condition of the device 1 snow in the tread of the tire and thereby also in the area of the supporting surface of the tire lies between the wheel of the vehicle and the ground and increase traction on slippery ground. Items 2 clutch may contain, as schematically shown in figure 1, a cross-country network 2' chain branches 3 and transverse ridges 4 and the retaining elements 5.

The clutch elements 2 are held in place using at least one retaining e is ementa 6, for example, in the form of elastic deny disk or, as shown in the figure, in the form of specialisng retaining shoulders, which are made with the possibility of elastic deflection in the axial direction.

Cross-country network 2' is attached to the wheel of the vehicle using at least one retaining element 6 and the fixing device 7. The fixing device 7 can be located, as shown in figure 1, in the radial direction R in the middle, so that when assembled the anti-skid device 1 lies coaxially to the wheel of the vehicle in the area of the hub.

The fastening device 1 of the anti-skid wheel vehicle comes with a tension element 8, which may contain traction means 9a, for example, wire rope. In the shown embodiment, the tension element 8 has, in addition, having the form of a lever connecting part 9b with a clamping device 9c, which is fixed on the wheel nut or bolt wheels. Traction means 9a is preferably connected to rotate with the connecting part 9b, so that the anti-skid device 1 can work to shift the vehicle's wheel in the circumferential direction U, without education sites on the traction means 9a.

For actuation of the tension element 8 mounting the lighting is ie 7 is in the middle of the handle 10, which on the withdrawal of the anti-skid device 1 with the wheels of the vehicle in the opposite axial direction As the wheels of the vehicle pulling direction Z and the relative compression of the anti-skid device 1 to the wheel of the vehicle facing in the axial direction And to a wheel of the vehicle prijemnom direction D performed ergonomic. At the same time the user can influence through the handle 10 on the tension element 8 with the aim of creating required for installation of anti-skid tension force.

In particular, the handle 10 has an ergonomic, fully assembled facing in the axial direction And from the wheels of the vehicle pressure surface 11a, which has a value hand. Favorable from the point of view of ergonomics execution in the form of a gripping element 10' is obtained, for example, due to the essentially smooth without protrusions and grooves, which can press on lying on a pressure surface 11a of the palm. In addition, the push surface 11a may be made slightly convex to better fit the palm of your hand when clicked.

To facilitate removal of the anti-skid device 1 with the wheels of the vehicle in the Z-direction traction manually without tool handle may be turned in Montero the data state in the axial direction And to a wheel of the vehicle, ergonomic traction surface 11b. Such traction surface 11b is obtained, for example, due to the undercut 12 arm in the axial direction, so that passing occurs in the circumferential direction U of a gripping depression and/or depression for fingers. Due to the undercut 12, the handle 10 is shown in figure 1 embodiment, the essentially mushroom-shaped structure.

In addition, the handle 10 may be made preferably can be rotated in the circumferential direction U with the aim of bringing into action of the tension element 8. To facilitate rotation of the handle 10 manually can be provided facing in the circumferential direction U of the support surface 13A, which provide a support for the fingers when turning the knobs 10. Shown in figure 1 embodiment, the bearing surface 13A is made in the form of passing in the axial direction And uniformly distributed in the circumferential direction U of the depressions 13b for fingers and/or gripping depressions shaped head extending arm 10. Gripping depressions 13b end in passing in the circumferential direction U of the undercut 12, so that your fingers cover occurs between the gripping depressions protrusions 13b 13C and easier to get support.

Additionally, the handle 10 is installed to be movable in the Z-direction traction to overcome the tension of the spring C is the speed, as will be explained below with reference to shown in figure 2 variant execution.

Figure 2 shows in perspective and in section of another embodiment of the handle 10. For simplicity, figure 2 uses the same designation of positions as in figure 1.

Shown in figure 2, the handle 10 is made slightly differently than shown in figure 1 the handle 10 so that it is held in the circumferential direction U of a gripping depression 13b, and made essentially in the form of a cap with essentially kropielnicki circumferential surface, which with uniform intervals provided with gripping depressions 13b, which should provide support for removing the anti-skid device, and rotation of the handle 10.

The handle 10 is installed can be rotated in the circumferential direction U around pin 15 ground element 16. In the traction direction of the Z arm 10 is also supplied with a ground element 16. For example, concatenated with a ground element 16 having the form of a spigot emphasis 17A prevents the retraction of the handle 10 with a ground element 16 when removing the unit 1 anti-skid wheel 1' of the vehicle in traction direction Z. the Spring element 17b, for example, conical spring, presses the handle 10 opposite to the pulling direction Z in the direction of the vehicle wheels is to the ground element 16.

The spring element 17b, as shown in figure 2, may be mounted coaxially around the trunnion 15 and rely on the stop 17A and the handle 10. To adjust the anti-skid device 1 when mounted close to the wheel 1' of the vehicle mounting fixture provided with a tensioning mechanism 18, which presses the handle 10. By actuating the tensioning mechanism 18 by means of a lever 10 is created, transmitted depicted only schematically in figure 2, the tensioning element 8 power's tension between the anti-skid device 1 and the wheel rim. The tensioning mechanism 18 may have a winding device 19 for the tension element 8, which is performed as follows.

Through the Central opening 20 in the ground element 16 of the tension element 8 is included in the fixing device 7 essentially in the axial direction and is directed through a bent from the axial direction And in the circumferential direction U of the guide channel 21 in the ground element 16 to the annular winding channel 22. In one place the tension element 8 is connected with the handle 10, so that it by turning the knob 10 in the circumferential direction U is drawn through the guide channel 21 in the winding channel 22 and there is wound. To reduce friction between the tensioning element 8 and the ground element 16, and a handle 10 and a ground element 6 ground element 16 preferably is made of durable plastic with a low coefficient of friction, such as, for example, fiber-glass reinforced polyamide.

Due to the winding tension element 8 is mounted on a wheel rim connecting part 9a of the fixing device 7 when the elastic deformation of the retaining element 6 is pressed against the wheel of the vehicle. Through the handle 10, the user actuates the winding device 19, so that there is a force of the tension that during acceleration of the vehicle independently puts the anti-skid device for a wheel of the vehicle and hold it in also during the passage of turn.

Self-locking tensioning mechanism S is achieved by means of a clamp 23, which may be performed, for example, in the form of two rotatable relative to each other, facing in the axial direction And sawtooth profiles 24, 25, as shown in figure 3.

One sawtooth profile 24 is made koltseobrazno on the ground element 16 protruding in the axial direction And from the vehicle wheels by the saw teeth. Another sawtooth profile 25 is made on the handle 10, as shown in figure 3, and is engaged with a sawtooth profile 25 ground element 16. The shape of the sawtooth profiles 24, 25 are chosen so that is self-locking when the winding tension element 8 power's tension affects Natai the second item 8.

When the winding tension element 8 sawtooth profiles 24, 25 slide over each other with an axial deviation of the arm 10 against the action of the spring element 18. Random rotation of the handle in the opposite direction is not possible because the spring element 17b presses the handle 10 with a sawtooth profile 25 to sawtooth profile 24 ground element 16.

To release the tensioning mechanism 18 is necessary to move the handle 10 in the second, non-Executive direction during actuation of the tension mechanism direction. Shown in the figure 3 embodiment, this is due to the fact that the arm 10 is lifted against the action of the spring element 17b in the pulling direction Z from the ground element 16. This Executive direction is perpendicular to the Executive direction when winding and, in particular, opposite the clamping direction D, so as to prevent accidental release and thus incorrect operation when pressing the anti-skid device 1. At the same time when removing the anti-skid device 1 with the wheels of the vehicle automatically by means of a lever 10 is released, the tension mechanism 18. Thus, the handle 10 is in the shown embodiment, as deblokiruyuschee switch 26 for Tarnovo mechanism.

The ground element 16 may be, as shown in the figures secured to the support element 27, for example, by clamping. On the host element 27 mounted holding elements 6. In addition, the ground element 16 is preferably installed without the possibility of turning relative to the support member 27.

Figure 4 shows another embodiment of the invention, once again, for simplicity, uses symbols as in figure 1-3. Shown in the embodiment of figure 4 differs from the scenarios according to figure 2 and 3 are integrated in the handle 10 of the indicator element 28. The indicator element 28 shows the use of the precautionary element 29 creating a user through actuation of the handle 10 is sufficient for automatic residual installation labor Sminthe tension in the tension element 8 or, respectively, the traction means 8'.

The indicator element 28 is mounted for movement depending on existing in the tension element 8 force's tension and placed in a position in which the warning element 29 is perceived by the user during installation, i.e. visible or felt. A warning element 29 contains in this case characterized by a color signal relative to the stop 17A edge of the arm 10. In the final assembled Polo is the situation, shown in figure 4, the warning element 29 is closed by the stop 17A and is not visible to the user.

This function is shown in figure 4 embodiment, the fact that unlike the previous embodiments emphasis 17A is fixed not on the ground element 16, and a bearing element 27, and the pin 15 is formed by a supporting element 27. The ground element 16 due to the pull of the tension element with the force's tension in the axial direction relative to the support member 27 is moved relative to the arm 10 and the ground element 16 of the trunnion 15. The length L of the path of the shift of the ground element is limited by the lugs 31, which are formed locking elements 32, with which the ground element 16 secured to the support element 27. The length L is smaller than the height of the sawtooth profiles 24, 25, so that the retainer 23 can not be released due to the shift of the ground element 16 relative to the arm 10.

The spring element 30 may be made as shown in the figure, in the form of Belleville springs, in particular, in the form of a snap spring which, when exceeding a certain force suddenly develops. Disc spring has a slot (not shown) to the guide channel 21.

The modulus of elasticity of the spring element 30 preferably greater modulus of elasticity of the spring element 17b, so that in the pre-Assembly position with Renata atom tension element 8 ground element 16 is pressed against the action of the spring element 17b from the support member 27 to the lugs 31 with the passion of the handle 10. In this position, the handle 10 is moved for facing the pressure surface 11a of the end stops 17A and a warning element 29 becomes visible to the user in the recess 17c of the handle 10.

If the user based on the pre-Assembly position, pull through the arm 10 of the tension element 8, the tension element 8 acts increasing the force's tension, which pulls the ground element 16 by overcoming the action of the spring element 30 to the supporting element 27. On the basis of the spring force of the spring element 17b arm 10 follows the movement of the ground element 16 and is moved in accordance with the force's tension relative to the stop 17A. When reaching required for reliable automatic residual installation labor Smintension warning element 29 is closed by the stop 17A.

To remove the anti-skid device 1, the user acts as in the examples according to figure 2 and 3: the arm 10 is, as before, as deblokiruyuschee switch 26 and is drawn traction in the Z-direction against the action of the spring element 17b, until you reach the latch 23. In this first ground element 16 follows the arm 10 under the action of the spring element 30, while this movement after stroke L is stopped by the stops 31. Then use ostate the tion of movement of the turn is derived from the engagement of the latch 23. Thus, the stroke H of the ground element 16 relative to the support member 27 is at least equal to the sum of the stroke L and the height of the sawtooth profiles 24, 25.

Possible modifications of the above embodiments. So, instead of rolling in the axial direction And the handle 10, it can be made stationary in the axial direction And, instead, having the form of a spigot stop 17 can be made as deblokiruyuschee switch 26, which when narimani withdraws from the engagement of the latch 23. This can be accomplished, for example, due to the fact that the ground element 16 with the stop 17 is moved against the action of the spring element in the direction of compression, and sawtooth profile 24 is withdrawn from engagement with the sawtooth profile 25.

Naturally, other embodiments of the tensioning mechanism and smallacombe. For example, sawtooth profiles 24, 25 may also be directed in the circumferential direction and to be released with the help installed on a circumferential surface of the arm 10 of a button. In addition, actuation of the tension element by using the handle 10 can be performed through an intermediate gear included elements, which, however, complicates the design. Finally, you can use the arm 10 is also directly tighten and loosen as a tensioning element of the screws is e or a clamping connection with a wheel of the vehicle.

Instead of or in addition to, apparently had not yet reached the minimum strength of Smintension warning element 29 may also be provided for permitting the element, which signals the user that have not yet reached the minimum strength Sminthe tension.
