Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automobile wheel cover mounting structure.
[0002]
[Prior art]
Generally, a bulge protruding outward in the radial direction called a hump is formed at a predetermined position of a rim portion of a disk wheel, particularly a steel wheel, thereby preventing the tire end from moving inward. However, various vehicle wheel cover mounting structures for mounting a wheel cover using this hump have been proposed.
[0003]
For example, in the mounting structure shown in FIG. 1, a plurality of locking claws 3 are integrally formed around the back surface of a resin wheel cover main body 2 of the wheel cover 1, and the locking claws 3 are attached to the hump 6 of the disc wheel 5. The wheel cover 1 is attached to the disc wheel 5 by forcibly fitting and further backing up the locking claw 3 with a wire ring 4 and urging it radially outward to suppress creep of the resin locking claw 3. .
[0004]
However, in such an attachment structure, when the wheel cover 1 is attached / detached, a large load is applied to the wheel cover 1 in order to forcibly move the locking claws 3 inward in the radial direction. Therefore, the attaching / detaching work is not easy.
[0005]
There are many types of disc wheels 5, and there are various types even if they have the same diameter. In many cases, the position and depth of the hump are different for different types. Therefore, when the wheel cover 1 is attached to the disc wheel 5 using the hump 6, the wheel cover 1 has to be dedicated to each type of disc wheel 5, and is not versatile. .
[0006]
[Problems to be solved by the invention]
Therefore, the technical problem to be solved by the present invention is a highly versatile automobile that can be attached / detached with a small force and can be mounted regardless of the type of disc wheel having the same standard diameter. It is to provide a wheel cover mounting structure.
[0007]
[Means for solving the problems and actions / effects]
As described above, if the type of the disc wheel 5 is different, the position of the hump 6 is different even if the standard diameter is the same. However, the dimensions of the rim flange 7 of the disc wheel 5 are substantially the same regardless of the model if the standard diameter dimensions are the same.
[0008]
The present invention has been made paying attention to this point, and solves the above technical problem by attaching the wheel cover to the disc wheel 5 by using the rim flange 7 instead of the hump 6.
[0009]
In the mounting structure for an automobile wheel cover according to the present invention, the wheel cover is attached to the disc wheel via the fastening means. The wheel cover has a plurality of mounting bosses that are provided at appropriate intervals in the circumferential direction around the back surface of the disk-shaped wheel cover main body and project in the axial direction toward the disk wheel. The tightening means includes a plurality of clip members, a wire member, and a wire coupling member. The said clip member consists of a main-body part and a curved part. The main body is fixed to the mounting bosses of the wheel cover so as to be slidable in the radial direction. The curved portion is connected to the radially outer side of the main body, has a shape substantially along the outer peripheral surface of the rim flange of the disc wheel, and can be engaged with the outer peripheral surface of the rim flange of the disc wheel. is there. The main body has a wire engaging portion with which the wire member is engaged. The wire member is a single wire member that sequentially engages with the wire engaging portion of the main body portion of each clip member in the circumferential direction, and the clip member is radially inward by reducing this winding. It is possible to pull on. The said wire coupling member fixes the said winding of the said wire member so that cancellation | release is possible.
[0010]
In the above configuration, in order to attach the wheel cover to the disc wheel, first, each clip member is set to the radially outer position, and the curved portion of each clip member is radially outward from the rim flange of the disc wheel. On the disc wheel. Next, the wire member is pulled to reduce the winding of the wire member, the clip member is moved radially inward, and the curved portion of the clip member is engaged with the outer peripheral surface of the rim flange of the disc wheel. The curved portion of the clip member is preferably one that elastically engages the rim flange. Finally, the wire member is used to fix the winding of the wire member so that the winding is not loosened. If the winding of the wire member is not loosened, the clip member does not move radially outward, so that the engaged state between the curved portion of the wire member and the rim flange of the disc wheel is maintained. That is, the wheel cover is held while being attached to the disc wheel.
[0011]
In the above configuration, by reducing the winding of the wire member, the wheel cover can be attached to the disc wheel, and it is not necessary to force the wheel cover into the disc wheel. Therefore, the attaching / detaching operation can be performed with a small force.
[0012]
In the above configuration, the clip member engages with the rim flange instead of the hump of the disc wheel. As described above, the position and size of the rim flange are not related to the model if the disc wheel has the same standard diameter. It is almost the same. Therefore, if the mounting structure of the present invention is a disc wheel having the same standard diameter, the wheel cover can be attached to the disc wheel regardless of the type, and the versatility is high.
[0013]
Furthermore, a wheel cover can be attached to a disc wheel without a hump. In addition, since the clip member can be disposed at an arbitrary position in the circumferential direction of the rim flange, even if the balance weight is attached to the rim flange, the degree of freedom in mounting the wheel cover is not limited.
[0014]
Preferably, the wire coupling member includes a fixing portion to which one end side of the wire member is fixed, a winding shaft around which the other end side of the wire member is wound, and a ratchet mechanism coupled to the winding shaft.
[0015]
In the above configuration, in order to attach the wheel cover to the disc wheel, the other end side of the wire member is wound around the winding shaft of the wire coupling member, the wire member is wound up, and the winding of the wire member is reduced. Since the ratchet mechanism is coupled to the winding shaft, the winding of the wire member can be fixed so as to be released. That is, the winding state of the wire member can be fixed and the attached state of the wheel cover can be maintained. On the other hand, if the ratchet mechanism is released, the wire cover can be loosened and the wheel cover can be removed.
[0016]
Therefore, the operation when the wheel cover is attached to and detached from the disc wheel becomes easy.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Below, the attachment structure of the wheel cover for motor vehicles based on embodiment of this invention shown in FIGS. 2-9 is demonstrated in detail.
[0018]
In the wheel cover attachment structure of this embodiment, the wheel cover 10 is attached to the disc wheel 5 by engaging the clip member 20 of the wheel cover 10 with the outer peripheral surface of the rim flange 7 of the disc wheel 5.
[0019]
That is, the wheel cover 10 has a plurality of mounting bosses 14 around the back surface of the cover body 12 as shown in the cross-sectional view of the main part in FIG. The mounting bosses 14 are integrally molded with resin together with the cover body 12 at a predetermined interval in the circumferential direction, and project straight in the axial direction. A clip member 20 is fixed to the end portion of the mounting boss 14 by a screw 16 so as to be slidable in the radial direction.
[0020]
Specifically, as shown in the exploded perspective view of the main part of FIG. 3, the clip member 20 is formed by bending one metal plate, and is bent in a substantially semicircular shape from the central intermediate part 22 and one end of the intermediate part 22. And a right-angled end portion 26 that is bent at a right angle from the other end of the intermediate portion 22 to the same side as the curved end portion 24. A long hole 23 extending in the longitudinal direction is formed in the intermediate portion 22 of the clip member 20. The width of the long hole 23 is larger than the axis of the screw 16 and smaller than the head of the screw 16. The screw 16 is inserted into the long hole 23 so that the clip member 20 can slide on the boss 14 of the wheel cover 10. It can be fixed. The clip member 20 is fixed to the wheel cover 10 such that the curved portion 24 is on the radially outer side and the right-angle end portion 26 is on the radially inner side. The curved end portion 24 of the clip member 20 has a shape that can be engaged with the outer peripheral surface of the rim flange 7 of the disc wheel 5 and is thin and elastic. The right-angle end portion 26 of the clip member 20 is formed with a wire insertion portion 27 for allowing the wire member 30 to pass therethrough.
[0021]
As shown in the schematic diagram of FIG. 4 and the plan view of FIG. 5, the wire member 30 is sequentially inserted in the circumferential direction in the wire insertion portion 27 of the right-angle end portion 26 of each clip member 20 arranged at appropriate intervals in the circumferential direction. As a result, the clip member 20 can be pulled and moved radially inward by pulling the end of the wire member 30 to make the winding smaller. Both ends of the wire member 30 are releasably coupled by a wire fastening member 40 described later, and can be held so that the winding does not loosen.
[0022]
When the wire member 30 is pulled and the winding is reduced, the clip member 20 moves radially inward from a radially outer position indicated by a chain line in FIG. 2 to a radially inner position indicated by a solid line. Accordingly, the curved end portion 24 of the clip member 20 is elastically engaged with the outer peripheral surface of the rim flange 7 of the disc wheel 5.
[0023]
The wire member 30 may be made of metal, cloth such as a seat belt, or resin such as a fishing line, and a retaining member 33 is fixed to both ends.
[0024]
The wire fastening member 40 is divided into a main body 42 and a lid 44 as shown in an external view of FIG. 6, a cross-sectional view of a main part of FIG. 7, and a perspective view of FIG. 8. One end side 32 and the other end side 34 of the wire member 30 are inserted.
[0025]
A first insertion portion 46 configured such that one end side 32 of the wire member 30 is inserted into the main body 42 and a retainer 33 fixed in the vicinity of the one end 31 of the wire member 30 is engaged, and a wire The second insertion portion 48 through which the other end side 34 of the member 30 is inserted, the winding shaft 50 around which the wire member 30 inserted through the second insertion portion 48 is wound, and the other end of the wire member 30 wound around the winding shaft 50 A third insertion portion 49 through which the side 34 is inserted and a ratchet mechanism 52 coupled to the winding shaft 50 are provided. The ratchet mechanism 52 includes a ratchet gear 54 and a lever member 56. The ratchet gear 54 is fixed to the winding shaft 50. The lever member 56 is pivotally supported at the center, has one end side removably engaged with the external teeth of the ratchet gear 54, and has a release button 58 protruding outside the wire fastening member 40 on the other end side. The wire tightening member 40 may be attached to the disk wheel 5 with a clip by providing a magnet on the back surface thereof and attracting and fixing to the disk wheel 5.
[0026]
As shown in FIG. 8, the wire member 30 is wound twice around the winding shaft 50. As shown in FIG. 6, the wire member 30 is wound up by inserting a tool from the rotation hole 47 of the main body 42 and rotating the winding shaft 50. be able to. At this time, since the winding shaft 50 is normally rotatable only in the winding direction by the ratchet mechanism 52, the wire member 30 can be wound up to reduce the winding without loosening the winding. On the other hand, when the release button 58 of the ratchet mechanism 52 is pressed, the engagement between the ratchet gear 54 and the lever 56 of the ratchet mechanism 52 is released, and the winding shaft 50 can rotate in the reverse direction, so that the winding of the wire member 30 is loosened. Can do.
[0027]
Next, a procedure for attaching and detaching the wheel cover 10 will be described.
[0028]
First, the wheel cover 10 is placed on the disc wheel 5 with the clip member 20 in the radially outer position. At this time, as shown by a chain line in FIG. 2, the curved end portion 24 of each clip member 20 is disposed outside the rim flange 7 of the disc wheel 5. Next, by inserting a tool into the rotation hole 47 of the wire clamping member 40 and rotating it, the wire member 30 is wound up to reduce the winding, and each clip member 20 is moved in the radial direction as shown by a solid line in FIG. The curved end 24 of the clip member 20 is engaged with the rim flange 7 of the disc wheel 5 by moving to the inner position. At this time, the curved end portion 24 of the clip member 20 is engaged with the rim flange 7 of the disc wheel 5 that is curved and protrudes radially outward, so that the wheel cover 10 is axially and circumferentially moved with respect to the disc wheel 5. Fixed to. On the other hand, when the wheel cover 10 is removed, the release button 58 of the wire clamping member 40 is pushed to loosen the winding of the wire member 30 and the curved end 24 of the clip member 20 is moved radially outward to move the rim flange of the disc wheel 5. This is done by releasing the engagement with 7.
[0029]
As described above, the wheel cover 10 may be attached / detached simply by rotating the winding shaft 50 of the wire fastening member 40 or pressing the release button 58 of the wire fastening member 40. Therefore, the wheel cover 10 can be attached and detached with a small force.
[0030]
Even if the type of the disc wheel 5 is different, there is almost no variation in the shape and position of the rim flange 7, so that the wheel cover 10, the clip member 20, the wire member 30, and the wire tightening member 40 can be shared. Therefore, if the wheel cover 10 is a disc wheel 5 having the same standard diameter, the wheel cover 10 can be a highly versatile wheel cover that can be mounted regardless of the model. In addition, the wheel cover 10 can be easily replaced. This is because the radial position of the clip member 20 can be freely changed by merely adjusting the winding amount of the wire member 30 by the tire tightening member 40.
[0031]
Furthermore, the structure of the mounting portion is simple, and the wheel cover 10 can be structured without a mold slide by making the wheel cover main body 12 thin and straightening the mounting boss 14 on the back surface thereof. Therefore, it is possible to reduce the cost, weight, and lead time of the wheel cover 10.
[0032]
In addition, this invention is not limited to the said embodiment, It can implement in another various aspect. For example, the shape and size of the mounting boss 14 provided on the back surface of the wheel cover main body 12 are arbitrary, and are not limited to small protrusions. It may be large. Further, instead of the wire tightening member 40 of the above type, a simplified wire tightening member 40 ′ shown in FIG. 8 may be used. However, in the case of this wire fastening member 40 ′, the diameter reduction dimension when the wire is tightened is constant. This member 40 'is constituted by three plates 40a, 40b and 40c hinged to each other. One end of the wire member 30 is connected to the end of the plate 40a, and the other end is connected to the end of the plate 40c. Openings 40d and 40e are provided in the central portions of the plates 40a and 40b, respectively. On the other hand, the center portion of the plate 40c has an opening 40f and a cut and raised locking piece 40g protruding downward. When the wire member 30 is relaxed, the plates 40a, 40b, and 40c are unfolded linearly as shown in FIG. 9 (I). On the other hand, when the wire member 30 is tightened, the three plates 40a, 40b, and 40c are folded as shown in FIG. 9 (II). At this time, the cut-and-raised locking pieces are inserted into the openings 40e and 40d of the plates 40b and 40a and locked around the openings of the plates 40a.
