Description

[Technical Field]

[0001] The present invention relates to a buffer member and a window regulator. [Background technology]

[0002] Conventionally, a damper is used as a buffer member and is attached to the base plate of an arm-type window regulator to absorb impacts on the base plate (see Patent Document 1). This damper has a plate-shaped buffer section made of a wear-resistant soft material such as rubber or resin, an insertion section extending from the center of the buffer section and inserted into a mounting hole formed in the base plate, and a flange section formed at the tip of the insertion section. In this damper, the length of the insertion section (insertion allowance) is approximately the same as the plate thickness of the base plate, which makes it possible to suppress rattling of the damper when attached to the base plate.

[0003] [Patent Document 1] Publication No. 55-56864 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with conventional shock absorbers, the length of the insertion section is made almost the same as the plate thickness of the component, so the flange does not pass through the mounting hole unless the shock absorber is pressed firmly against the component, making it impossible to mount the shock absorber. This has led to the problem of poor workability in mounting the shock absorber.

The flange portion has an extension portion extending from the tip of the insertion portion, and a plurality of contact pieces formed to protrude from the circumferential surface of the extension portion, arranged at intervals from each other, and in contact with one of the front and rear surfaces. The present invention provides a cushioning member characterized by the above-mentioned.

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, a buffer member and a window regulator according to one embodiment of the present invention will be described with reference to the accompanying drawings. This window regulator is a lifting device that is attached to the inside of a door of a vehicle (e.g., an automobile) and raises and lowers the window glass of the door. In particular, this window regulator is equipped with a buffer member whose shape has been designed to improve installation workability. Note that, hereinafter, the direction in which the window glass is raised and lowered will be simply referred to as the lifting and lowering direction. Furthermore, hereinafter, left and right, front and rear, and top and bottom will be defined as shown in the drawings. Furthermore, in this embodiment, it is assumed that the width direction of the vehicle and the front and rear direction of the window regulator coincide with each other.

[0011] (Window regulator configuration) 1 and 2, the window regulator 1 includes two glass holders 11, 11 fixed to the lower end of a window glass 10, an arm bracket 12 to which the window glass 10 is attached via the two glass holders 11, 11, a lift arm 13 having a tip end 13a connected to the arm bracket 12 to raise and lower the arm bracket 12, a sector gear 14 fixed to the base end of the lift arm 13, a drive unit 15 that drives the lift arm 13 via the sector gear 14, and a support base 16 fixed to the inner panel P of the door D and rotatably supporting the lift arm 13 via a support shaft 16a. In other words, the window regulator 1 is a single-arm window regulator.

[0012] The window regulator 1 also includes a buffer member 17 attached to the lift arm 13 to absorb impact from another component to the lift arm 13. In other words, the lift arm 13 is an example of a component to which the buffer member 17 is attached. Details of the buffer member 17 will be described later.

[0013] Each glass holder 11, 11 integrally comprises a glass holding portion 21 that holds the window glass 10 and a fastening portion 22 that is formed on the underside of the glass holding portion 21 and fastened to the arm bracket 12 by a screw 23. The lower end of the window glass 10 is held by the glass holding portion 21 and fixed to the glass holding portion 21 with an adhesive or the like.

[0014] The lift arm 13 is a long plate-like member formed by press-molding a metal plate. The base end 13b of the lift arm 13 is rotatably attached to a support shaft 16a of the support base 16, and the tip end 13a is connected to the arm bracket 12 via a slider (not shown) so as to be slidable in the left-right direction. When the lift arm 13 rotates around the support shaft 16a, the tip end 13a of the lift arm 13 moves in the lifting and lowering direction while sliding left-right, and the tip end 13a pushes up or down the arm bracket 12 in the lifting and lowering direction. This raises or lowers the window glass 10 via the arm bracket 12 and the two glass holders 11, 11. A circular mounting hole 13c (see FIG. 4(e)) is formed through the lift arm 13 at the longitudinal intermediate position, for mounting a buffer member 17.

[0015] 2, the sector gear 14 is formed in an arc shape and is fixed by welding or the like to the base end side of the lift arm 13. In addition, a gear portion that meshes with an output gear (described later) of the drive unit 15 is formed on the arc-shaped outer circumferential surface of the sector gear 14.

[0016] The drive unit 15 includes a motor 31 with a reducer that serves as a drive source, an output gear (not shown) that is axially attached to the motor 31 with a reducer and meshes with the sector gear 14, and a gear cover 33 that covers the output gear. The gear cover 33 is attached to the inner panel P of the door D and is formed integrally with the support base 16.

[0017] When the reducer-equipped motor 31 is driven in the forward direction, the output gear attached to the reducer-equipped motor 31 rotates in the forward direction, and the lift arm 13 rotates counterclockwise via the sector gear 14 meshed with the output gear. This causes the tip 13a of the lift arm 13 to move upward while sliding left and right. This pushes the arm bracket 12 connected to the tip 13a of the lift arm 13 upward in the lifting / lowering direction, and the window glass 10 rises via the glass holders 11, 11.

[0018] On the other hand, when the speed reducer motor 31 is driven in the reverse direction, the output gear attached to the speed reducer motor 31 rotates in the reverse direction, and the lift arm 13 rotates clockwise via the sector gear 14 meshed with the output gear. As a result, the tip 13a of the lift arm 13 moves downward while sliding left and right. As a result, the arm bracket 12 connected to the tip 13a of the lift arm 13 is pulled downward in the lifting / lowering direction, and the window glass 10 is lowered via the glass holders 11, 11.

[0019] Next, the buffer member 17 will be described with reference to Figures 3 to 6. As shown in Figures 3 and 4, the buffer member 17 is made of resin and integrally comprises an inverted dish-shaped buffer section 51, a cylindrical insertion section 52 that extends rearward from the center of the buffer section 51 and is inserted into the mounting hole 13c of the lift arm 13, and a flange section 53 formed at the tip of the insertion section 52. In other words, the buffer section 51 forms a main body section that contacts the surface of the lift arm 13 and also contacts other components to absorb impacts from those other components, and the insertion section 52 and the flange section 53 form mounting sections for mounting the buffer section 51 to the lift arm 13.

[0020] The insertion portion 52 is formed in a cylindrical shape, with a buffer portion 51 formed at its base end and a flange portion 53 formed at its tip. As shown in FIG. 4(e), the length of the insertion portion 52 is formed to be longer than the depth of the mounting hole 13c (i.e., the plate thickness of the lift arm 13). Note that the length of the insertion portion 52 is preferably equal to or greater than the depth of the mounting hole 13c plus the radial dimension of the contact piece 62 (described later).

[0021] The flange 53 has an extension 61 extending from the tip of the insertion portion 52, and four fan-shaped contact pieces 62 formed and protruding from the circumferential surface of the extension 61. The four contact pieces 62 are arranged on the top, bottom, left, and right sides of the extension 61, and are arranged at intervals from each other in the circumferential direction of the extension 61. As shown in FIG. 4(e), when the buffer member 17 is attached to the lift arm 13, each contact piece 62 is located on the rear surface (i.e., the back surface) of the lift arm 13 and comes into contact with the rear surface of the lift arm 13. This prevents the buffer member 17 from coming off the lift arm 13.

[0022] As shown in FIG. 4, the buffer section 51 is formed in a circular shape centered on the insertion section 52 when viewed in the axial direction of the insertion section 52, and has an inverted dish shape with the outer edge of the disk bent backward. That is, the buffer section 51 is formed in a convex shape with the center protruding forward (the side opposite the lift arm 13). Also, as shown in FIG. 4(e), when the buffer member 17 is attached to the lift arm 13, the outer edge 51a of the buffer section 51 contacts the front surface (i.e., the surface) of the lift arm 13. That is, the buffer section 51 contacts the front surface of the lift arm 13 and is made of a bent elastic member. As a result, the buffer section 51 contacts another component approaching the lift arm 13 and absorbs impact from the other component by its bending elasticity. In this embodiment, it is assumed that the buffer section 51 absorbs impact from the glass holder 11, which is a separate component.

[0023] Specifically, as shown in Figures 2(c) and 5(a), when the window glass 10 is half-open, the right glass holder 11 is in a state close to the lift arm 13. If the door D is closed in this state, as shown in Figure 5(b), the glass holder 11 collides with the lift arm 13 via the buffer member 17 due to the impact when the door D is closed. At this time, the buffer portion 51 is bent so that the convex shape is crushed, and the impact from the glass holder 11 is absorbed by the elastic force of the bending elasticity during this bending deformation. Strictly speaking, the impact from the glass holder 11 to the lift arm 13 is absorbed by this bending elasticity and the elasticity of the material of the buffer portion 51 itself (i.e., compressive elasticity).

[0024] In this way, by constructing the buffer section 51 from a bent elastic member, the bending elasticity can absorb impacts from other parts, thereby improving the impact absorption effect of the buffer section 51.

[0025] The bent portion of the buffer portion 51 is formed thicker than other portions of the buffer portion 51. Furthermore, the buffer portion 51 has four openings 51b formed at positions corresponding to the four contact pieces 62 of the flange portion 53.

[0026] 4(d), the buffer section 51 is formed so that the outer edge 51a reaches the flange 53 in the axial direction of the insertion section 52. As a result, as shown in FIG. 4(e), when the buffer member 17 is attached to the lift arm 13, the outer edge 51a of the buffer section 51 comes into contact with the front surface of the lift arm 13, and the buffer section 51 is bent and deformed so that its convex shape is slightly crushed from its natural state. Then, the restoring force of the bending deformation attracts the flange 53 to the rear surface of the lift arm 13 via the insertion section 52. As a result, the outer edge 51a of the buffer section 51 and the flange 53 (each of the contact pieces 62) can be closely attached to the front and back surfaces of the lift arm 13.

[0027] Next, with reference to Figure 6, the mounting operation of the buffer member 17 for mounting the buffer member 17 to the lift arm 13 will be described. In the mounting operation of the buffer member 17, first, as shown in Figures 6(a) and (b), an operator inserts the flange 53 of the buffer member 17 into the mounting hole 13c. At this time, as shown in Figure 6(b), the four contact pieces 62 of the flange 53 deform so as to lean forward, allowing the flange 53 to be inserted into the mounting hole 13c.

[0028] After inserting the flange portion 53 into the mounting hole 13c, the worker pushes the center portion of the buffer portion 51 toward the lift arm 13, thereby inserting the flange portion 53 and the insertion portion 52 into the mounting hole 13c. Then, as shown in FIG. 6(c), when the buffer portion 51 is fully pushed in, the flange portion 53 passes over the mounting hole 13c, the four contact pieces 62 return to their natural state, and the convex shape of the buffer portion 51 is completely flattened and bent to a substantially flat plate shape. When inserting the insertion portion 52 into the mounting hole 13c, the length of the insertion portion 52 of the buffer member 17 is longer than the depth of the mounting hole 13c (the thickness of the lift arm 13). This makes it easier for the flange portion 53 to pass over the mounting hole 13c and for the four contact pieces 62 to return to their natural state. This allows the buffer member 17 to be smoothly attached to the lift arm 13.

[0029] Thereafter, when the worker releases the pressure on the buffer portion 51, as shown in Figure 6(d), the restoring force of the bending deformation in the buffer portion 51 attracts the flange portion 53 to the rear surface of the lift arm 13 via the insertion portion 52. As a result, the outer edge portion 51a of the buffer portion 51 and the flange portion 53 come into close contact with the front and rear surfaces of the lift arm 13. This completes the installation operation.

[0030] (Actions and Effects of the Embodiments) As described above, according to the configuration of the above embodiment, when the buffer member 17 is attached to the lift arm 13, the flange portion 53 is attracted to the lift arm 13 by the restoring force of the bending deformation in the buffer portion 51, thereby improving the workability of attaching the buffer member 17 and suppressing rattling of the buffer member 17.

[0031] That is, in the conventional shock absorber, the length of the insertion portion 52 was made approximately the same as the depth of the mounting hole 13c to suppress rattle of the shock absorber 17, but as a result of making the length of the insertion portion 52 approximately the same as the depth of the mounting hole 13c, the flange portion 53 did not pass through the mounting hole 13c and the shock absorber 17 could not be attached unless the shock absorber 17 was pushed hard into the lift arm 13. In other words, there was a problem in that the workability of attaching the shock absorber 17 was poor. In contrast to this, in the above embodiment, when the buffer member 17 is attached to the lift arm 13, the restoring force of the bending deformation in the buffer portion 51 attracts the flange portion 53 to the lift arm 13. As a result, even if the length of the insertion portion 52 is made longer than the depth of the mounting hole 13c (even if the insertion allowance is made long), the buffer portion 51 and the flange portion 53 can be brought into close contact with the lift arm 13, and rattling of the buffer member 17 can be suppressed.

[0032] That is, by making the length of the insertion portion 52 longer than the depth of the mounting hole 13c, the flange 53 can easily clear the mounting hole 13c when inserting the insertion portion 52 into the mounting hole 13c, and the contact piece 62 of the flange 53 can easily return to its natural state. This improves the ease of installation of the buffer member 17, and also allows the buffer portion 51 and the flange 53 to be tightly attached to the lift arm 13, thereby reducing rattle of the buffer member 17. In this way, both the ease of installation of the buffer member 17 and the reduction of rattle of the buffer member 17 can be achieved. Note that rattle of the installed buffer member 17 may cause a problem such as another component coming into contact with the buffer member 17 during lifting or lowering, resulting in the buffer member 17 coming off. Therefore, the configuration of the above embodiment can prevent such a problem by reducing rattle of the buffer member 17.

[0033] Furthermore, by configuring the buffer section 51 with a bent elastic member, the shock can be absorbed by bending elasticity, thereby improving the shock absorption effect of the buffer section 51.

[0034] Furthermore, by configuring the flange 53 with a plurality of contact pieces 62 arranged at intervals from one another, the flange 53 can be easily tilted down due to the intervals provided between the plurality of contact pieces 62. This makes it easier to insert the flange 53 into the mounting hole 13c, and makes it easier to mount the buffer member 17.

[0035] Furthermore, by forming the buffer section 51 in a perfect circle centered on the insertion section 52 when viewed from the axial direction of the insertion section 52, the buffer member 17 can be attached without having to worry about the attachment angle in the circumferential direction of the insertion section 52.

[0036] Furthermore, by forming the buffer portion 51 in a convex shape with the center portion protruding on the opposite side from the lift arm 13 side, the outer edge portion 51a of the buffer portion 51 can be brought into close contact with the lift arm 13. This makes it possible to prevent the outer edge portion 51a of the buffer portion 51 from getting caught on another component, causing the buffer member 17 to come off.

[0037] (Other embodiments) Although the embodiments of the present invention have been described above, the invention according to the claims is not limited to the above-described embodiments. It should be noted that not all of the combinations of features described in the embodiments are necessarily essential to the means for solving the problems of the invention. The present invention can be implemented by modifying it as appropriate within the scope of its spirit.

[0038] For example, in the above embodiment, the buffer portion 51 is formed in a perfect circle centered on the insertion portion 52 when viewed in the axial direction of the insertion portion 52, and the outer edge portion 51a contacts the surface of the lift arm 13 over the entire circumferential direction, but this is not limited thereto. For example, as shown in Fig. 7, the perfect circle of the buffer portion 51 may be formed into a substantially cross shape by providing notches 101 at four locations, namely the upper right, lower right, upper left, and lower left, so that only the outer edge portions 51a at the four locations, namely the upper, lower, left, and right, contact the surface of the lift arm 13. Note that in the modified example of Fig. 7, the number of contact locations is four, but the number of contact locations may be one, two, three, or five or more.

[0039] Furthermore, in the above embodiment, the buffer section 51 is configured to be formed in a perfect circle centered on the insertion section 52 when viewed from the axial direction of the insertion section 52. However, for example, the buffer section 51 may be formed in a polygonal shape including a rectangle when viewed from the axial direction of the insertion section 52, or may be formed in an elliptical or oblong shape when viewed from the axial direction of the insertion section 52.

[0040] Furthermore, in the above embodiment, the buffer member 17 and the buffer section 51 are made of resin, but for example, the buffer member 17 and the buffer section 51 may be made of rubber or the like.

[0041] Furthermore, in the above embodiment, the case where the separate part that collides with the lift arm 13 is the glass holder 11 has been exemplified, but depending on the structure of the window regulator 1, it is also conceivable that the screw 23 or the arm bracket 12 may collide with the lift arm 13. Therefore, it is also conceivable that the buffer member 17 may come into contact with the screw 23 or the arm bracket 12 to absorb the impact.

[0042] In addition, in the above embodiment, the target part is the lift arm 13 and the buffer member 17 is attached to the lift arm 13, but the target part may be the sector gear 14, the support base 16, etc. and the buffer member 17 may be attached to these.

[0043] In the above embodiment, the present invention is applied to a single-arm window regulator, but it may also be applied to an X-arm window regulator or a wire-driven window regulator. For example, the present invention may be configured such that the buffer member 17 is attached to a pulley bracket or a drum housing in a wire-driven window regulator. [Explanation of symbols]
