The level of technology

The present invention relates to a windshield wiper, especially for a vehicle, according to the restrictive part of claim 1 of the claims.

The prior art is already well known car wipers wide variety of designs, having a drive element mounted on the automobile body. Typically, these drive elements are firmly screwed to the car body, which, however, is rather time-consuming operation, requiring the use of multiple fasteners, such as screws, nuts and washers. This method of fastening actuating elements wiper is associated with relatively high logistical costs and, in addition, is a fairly complicated Assembly operation. From DE 10062617 A1 hereinafter known wiper mounted on the car glued connection with the use of glue, with damping properties.

From DE 19833404 A1 known windshield wiper for vehicles, especially for vehicles, for fastening to the body which uses a non-threaded connection, which thus allows to simplify and accelerate the installation of the wiper on the body. For this purpose, the wiper is equipped with a special bearing design for the drive device. Such carrier to the reconstruction there are several first fastening elements, protruding from her in the first direction. Such supporting structure has several second fastening element projecting from it in the second direction, forming with the first direction angle ranging from 45°to 135°, preferably an angle of 90°. The fastening elements are in the form of a cylindrical plug fingers that one of its end connected to the bearing structure, and other free - end is inserted into the planting hole with rubber-like elasticity of the damping element. Himself damping element inserted into the mounting hole in the vehicle body. Such an installation hole may be provided in welded to the car body curved corner or globorotalia the overlay. Push your finger to the possibility of locking in the damping element may have at its free end thickening, preferably conical. Since, however, the installation directions in which when the Assembly moves the first and second fastening elements are oriented at some angle to each other, there is a possibility of occurrence in the supporting structure upon completion of the installation of the mechanical stresses transmitted to the adjacent supporting structure of the body.

Advantages of the invention

In the proposed invention the wiper is empyreuma elements made in the form of mounting blocks having rubbery elasticity of the material. Such mounting blocks secured to the drive element and are arranged in such a way that they can be inserted into the planting hole by moving the first orientation direction, and then onto their available slot on the edge of the planting holes moving in the second installation direction transverse to the first installation direction. The slots in all of the mounting blocks and planting holes lie in the same plane or in different planes that are parallel to each other with an offset from each other in the first installation direction. The mounting blocks their slots securely hold the drive element fixed in the mounting holes, and the locking element holds the mounting blocks in their final position achieved when moved in the second installation direction, and thereby prevent movement of the mounting blocks on the end of the Assembly back in the opposite direction to the second installation direction, and jumping down from the planting holes. The planting hole may be provided directly to the sheet metal of the body or mounted on a sheet metal body, for example welded to it, the bracket.

The second installation direction lies in a plane transverse to the plane in which l is separated by the first shaft direction. In order to ensure the preservation of the output shaft of the drive element in its position when moving in the second direction of the output shaft, it is advisable to place in the position in which its axis is also the first orientation direction, and the fastening elements positioned mainly on tangents to a circle or concentric circles with the center lying on one axis of the output shaft straight or mainly parallel to the axis. In this case, the movement in the second installation direction represents the rotation around the axis of the output shaft, respectively, around a parallel axis.

The locking element is a pin with an elongated cross-section, which has on its outer side surface of the damping layer. In assembled position the locking element is passed through an elongated hole in the drive element and mounting hole in the body. But such an elongated hole, respectively installation hole lies in a plane transverse to the second installation direction, i.e. elongated in a generally radially relative to the output shaft when moving in the second installation direction represents the rotation around the axis of the output shaft. The damping layer, when viewed in the second installation direction, prelego the t to the walls of the elongated holes, accordingly, mounting holes, and therefore, in assembled position, the drive element has no rigid connection with the body, the mechanical vibrations of which are thus not transmitted to the wiper, and locked in this position. In the direction transverse to the second installation direction, may be provided in the gap to compensate for manufacturing and Assembly tolerances.

The damping layer is made of having rubbery elasticity of the material, which is applied in the form of a coating on a more solid main material of the locking element by spraying or to produce a separate item, stick to the basic material of the locking element, not on it or, if necessary, fix it some other way.

In one of the embodiments of the invention the locking element has at one end the flange, which it is in assembled position abuts against the drive element, and performed stepwise tapering in the direction of another my end, and in accordance with this adjacent to the flange section of larger cross-section is located in the elongated hole, and its narrower end section is included in the installation hole in the body. When facing the end of the locking element ledge rests on the edge ustanavochny the th hole in the body. The locking element such form provides in the area of its location between the driving element and the body of a guaranteed backlash eliminating the danger of formation between the transmitting sound vibrations hard links. This damping layer can outside to cover the basic material of the locking element and the area of the elongated hole, and on the site of the installation holes. However, to avoid a rigid connection between the wiper and the body in order to avoid transmission of mechanical vibrations from the body of the wiper damping layer is in principle sufficient to provide the retaining element is only located in the installation hole in the back area, while the area of the elongated hole of the fixing element can be your main material, which it is advisable to use suitable for this purpose, hard plastic, directly adjoin the edges of the elongated holes. The damping layer covering narrower in cross-section the end of the locking element, in the preferred embodiment, has two tabs. Thanks to the protrusions of the damping layer, the locking element is held in the planting hole in the back sort of clamping or snap connection from the side of his face closes met lichecki sheet body in the marginal zone of the mounting holes. These projections damping layer in the preferred embodiment, can be formed due to the presence of thickening the base material of the fixing element. Such thickening at the same time provide reliable retention of the damping layer on the base material of the fixing element.

In another embodiment of the invention the locking element is closed in the first installation direction of the elastic bracket having inside and outside on the damping layer, and a member of its closed end in the installation hole in the body. To the free ends of the elastic bracket adjacent unbent from them lamellar part that it is connected with a driving element. These plate part is formed with the free ends of the elastic staples such an angle that when installing a drive element in place of moving the first orientation direction of the plate part compress the elastic bracket and pressed to each other opposite portion of the inner damping layer. Both as the outer side of the damping layer is pressed while in the second installation direction to the edge of the mounting holes in the body. The closed end of the elastic bracket may be made in the form of thickening, which is inserted into the installation hole in the elastic body of the bracket from the back side caught the edge of this installation is about the holes.

For fastening one wiper usually require multiple fasteners and one locking element. It may be located separately from the fastening elements. In a preferred embodiment of the invention the locking element is combined with one of the fastening elements and in assembled position overlaps with the rear, if you look in the second installation direction side of the fastening element between the mounting block and the edge of the planting hole. Such solution allows to reduce the number of parts and/or simplify them.

In principle, the locking element may be in the form of separate, mostly non-compliance items are inserted into the above gap. This elastically deforms the mounting block. The locking element it is advisable to connect with the mounting block. In one of the embodiments of the invention the locking element is invited to perform in the form of a locking unit mounted on the mounting block with the offset it in the direction opposite to the first installation direction, and which can be shifted in the first installation direction immediately upon reaching the fixing block its end position. The locking unit can be connected to the mounting block shear jumpers, to the which, in the process of mounting the wiper moving the clamping block relative to the mounting block elastically deformed, tear or break off. In another embodiment, the locking unit connected to the mounting block longitudinal guide, such as guide in the form of a dovetail.

When mounting the wiper locking block is shifted relative to the mounting block in the direction opposite to the first installation direction, and thus does not prevent the imposition of the fixing unit in the planting hole and then moving the second installation direction. Upon reaching the fixing block its end position the locking block is moved in the first installation direction on the value of its initial displacement relative to the mounting block in a position in which it fills the gap between the mounting block and the wall of the mounting bore. The locking unit to prevent its inadvertent loss of the planting hole should be implemented with locking teeth, which in the assembled position of the stopper block abuts the edge of the planting hole with its front and back sides and in this way still fix the locking block.

In another possible embodiment, the locking element is invited to perform in the form of a locking element having ductility in the direction opposite to the first installation direction. In the process of assembling stcloudstate who I am locking the first element when moving the mounting block in the first installation direction elastically deflected from its original position in the direction opposite the first mounting direction, and then moving the mounting block in the second installation direction is provided on its end section locking prong drops at the end of this second installation move in the planting hole. In a preferred embodiment, the locking element has at its free end a stop, which in assembled position rests on the edge of the planting hole and thereby restricts the movement of the locking teeth in the direction of its saskachewan in the planting hole. In assembled provisions of the locking element lies in a plane approximately parallel to the plane in which lies the planting hole. With this arrangement, the locking element he works primarily in compression in its longitudinal direction and almost does not feel the effects of bending moments and effort, causing buckling.

Description of embodiments of the invention

1 schematically shows the wiper 10 rear window of the car. It is obvious, however, that the invention is not limited to the wipers rear CTE is ol cars. The invention with equal success can be used and applied to the windshield wipers windshields. The wiper 10 has a motor 12 and a gear mechanism 14, which together form a drive element 16. The actuator 16 has a body 18, which is partially implemented in the form of a casting and has a cantilever holders 20. At the ends of the two cantilever holders 20 are fasteners 22, and at the end of one cantilever holder 20 is provided the locking element 30.

Fasteners 22 are composed primarily of fixing blocks 76 (Fig), 90 (figure 10), 96 (Fig)mounted on the respective console holder 20, and is made of vibromassage elastic material with rubber-like elasticity. Under the fastening elements 22 in the vehicle body 26 is provided for mounting bore 24. Such planting holes are usually made directly to the sheet metal of the body or firmly United with the sheet metal body of the bracket.

Planting holes 24 are located in a plane transverse to the first installation direction 64. However, planting holes can be distributed across multiple mutually parallel planes. The mounting blocks 76, 90, 96 are inserted into the mounting bore 24 in the first installation direction 64 and then moved transversely to him in the second lips of the mounting direction 32 as long until the edge of the mounting bore 24 in the body 26 will rest against the bottom of the slot 78 of the corresponding mounting block. It is advisable that the first installation direction 64 is parallel to the axis of the output shaft 28 of the drive element 16. The second installation direction 32 in this case can represent the direction of rotary movement around the axis of the output shaft 28, while the mounting bore 24 and the fixing blocks 76, 90, 96 with their slits 78 must be on a tangent to the circles with centers lying on one axis of the output shaft 28 of the straight line. This design allows the Assembly to maintain constant the orientation and position of the output shaft 28, and use simple tools to seal provided in the body 26 of the hole of the output shaft 28.

Upon reaching the fixing blocks 76, 90, 96 moves in the second installation direction 32 of its end positions they fixed it with the locking elements 30, 52, 66, 92, 98. For each wiper requires only one such locking element 30, 52, 66, 92, 98. Shown in the figure 1 example, one fixing element 30 is located, regardless of the fastening element 22, and one locking element in the locking block 92 is used in combination with the fastening element 22. All fixing elements 30, 52, 66, 92, 98 is to be used, either individually or in combination with each other.

The basis of the locking element 30 (figure 2) forms the core 38 of a durable material such as plastic. The locking element has an oblong cross-section, which is shown in figure 1 embodiment is elongated in the radial relative to the output shaft 28 direction. The locking element 30 has a flange 40, which it is in assembled position rests on the cantilever holder 20. The flange 40 is turned to the body 26 of the adjacent side stepped part which their portion of larger cross-section is located in the elongated hole 48 in the console holder 20, and its end section 50 of smaller cross-section is included in the installation hole 34 in the body 26. The edges of this mounting holes 34 in the body 26 of the stub in the first installation direction 64 by education Board 36. The core 38 of the locking element 30 from its end portion 50 of a smaller cross-section and up to the flange 40 is covered fibrogenesis layer 44, which removes the hard link between the cantilever holder 20 and the body 26 and thereby prevents the transmission of mechanical vibrations from the body of the wiper. This layer 44 may be applied in the form of a coating on a more solid core 38 by sputtering, or may be formed separate, stick to it part. Because of the presence of the Bo is its solid core 38 is turned in the first installation direction 64 of the ledge 42 and layer 44 also has a corresponding step form with ledge which in assembled position the locking element (3) is adjacent to the edge of the mounting holes 34 and provides a gap 46 between the cantilever holder 20 and the body 26.

Shown in figure 4 and 5 the locking element 52 has a similar locking element 30 execution. However, in this case, its core 38 on the site of a larger cross-section is directly adjacent to the walls of the elongated holes 48 without interlayers of vibromassage layer 54, which reaches only to the ledge 42. At its end section 50 of reduced cross-section of the core has a thickness of 60 near the ledge 42 and another thickening 62 on the end. These thickenings 60, 62 fibrogenesis layer 54 forms on these sites protrusions 56, 58. The distance between these projections 56, 58 is such that the locking element 52 clicks into place in the installation hole 34 in the body 26 and thus provides a sufficiently wide gap 46 between the body 26 and the cantilever holder 20. Thickening 60, 62 provide, in addition, a reliable holding vibromassage layer 54 even when it is run as a separate part at the core of the locking element.

Shown in Fig.6 and 7, the locking element 66 has an elastic bracket 68 with a curved end 75. To the free ends of this elastic bracket 68 adjacent bent plate part 70, which is not shown in the drawing by way connected with the cantilever holder 20. The inner side of the elastic bracket 68 has fibrogenesis layer 72, and the outer side - covering its curved end 75 fibrogenesis layer 74. The curved end of the elastic bracket made thickened with dimensions slightly larger than the mounting holes 34, and therefore, in the final assembled position, the locking element 66 abuts against the edges of the flanges 36, surrounding the installation hole 34, securely holding the locking element in a fixed position. During installation, the locking element 66 by moving it in the first installation direction 64 of the bent plate part 70 elastically presses in a flattened position in which they compress the elastic bracket 68 and pressed to each other opposite portion of the inner vibromassage layer 72.

In the shown Fig-16 variants of the locking element 80, 92, 98 combined with the fastening element 76, 90, 96. In the shown Fig and 9 version made in the form of a locking unit 80 of the locking element shear jumpers 82 connected to the mounting block 76 and, in particular, offset it in the direction opposite to the first installation direction 64, to such a value that the first Seating hole 24 can be inserted is fixed on the cantilever holder 20 of the mounting block 76 and then to replace him in the second installation direction of the tion 32, pulled down over his slot 78 on the edge of the mounting bore 24 in the body 26. In this position in the planting hole 24 vidvigayt the locking unit 80, moving it in the first installation direction 64, while shear jumpers 82 break, break off or elastically deformed so that the locking unit 80 can fully enter into the gap between the mounting block 76 and the edge 88 of the mounting bore 24 (Fig.9). The stopper block is still fixed in the mounting hole adjacent to its edge 88 of the stop 86 on the one hand and the locking teeth 84 on the reverse side.

Figure 10-13 shows similar to the above option. In this embodiment, the locking block 92 is installed in the fixing unit 90 with the possibility of directional movement relative to him in the first installation direction 64 along the longitudinal guide rail 94. The fixing unit 90 is fixed on the cantilever holder 20 and has a slot 78. On the first Assembly stage (11) of the fixing unit 90 is inserted into the planting hole 24 to lock the top wall 104 of the slot 78 in facing to the wall surface of the body 26. In the next stage of the fixing unit 90 with the locking block 92 rotate in the second installation direction 32 before reaching the end position (Fig), in which the slot 78 is fully pressed down on the edge of the planting hole 24 in kuzo the E. 26. In a subsequent Assembly stage locking block 92 is shifted in the longitudinal guide 94 in the first installation direction 64 to the end position in which its stop 86 rests against the sheet metal of the body 26 on the one hand, and one of the locking teeth 84 still captures the locking block, resting on a sheet metal body 26 on the reverse side.

In the shown Fig-16 variant, the locking element serves as a stop element 98, which is provided with opposite notches 78 side of the mounting block 96 and has a ductility in a direction opposite to the first installation direction 64. This locking element 98 can be pinched inserted in the mounting block 96 of the elastic material, the elasticity of which is determined by the yielding of the locking element. In another embodiment himself locking element 98 can be made of a material with elasticity sufficient to enable its deflection in the direction opposite to the first installation direction 64, or can be pivotally connected to the mounting block 96. On the first Assembly stage mounting block 96 is inserted into the first mounting direction 64 in the planting hole 24 in the body 26 to lock the top wall 104 of the slot 78 in facing to the wall surface of the body 26. When this locking element 98 rests his acting is ome right angle locking tooth 100 in the body 26 and is resiliently deflected in the direction opposite the first installation direction 64. At the next Assembly stage of the fixing unit is moved in the second installation direction, push it to the slot 78 on the edge of the planting hole 24. Upon reaching the fixing unit when it is moved in the second installation direction 32 of its end position (Fig) stopping the teeth 100 of the locking element 98 drops into the planting hole 24 to the stop provided at the free end of the locking element 98 of the stop 102 in the body 26. In this position the locking element 98 closes the gap between the mounting block 96 and the edge 88 of the mounting bore 24.
