Description

  The present invention relates to a wheel cover attached to the front side of a tire wheel of a vehicle.

A resin wheel cover may be attached to a tire wheel of a vehicle for the purpose of preventing entry of water or mud into a disc brake or the like and improving the design.
As a method of attaching this type of wheel cover to a tire wheel, a method using a resin clip is known (for example, refer to Patent Document 1).
Patent Document 1 introduces a technique for attaching a wheel cover 7 to a disc wheel 1 via a wheel cover attachment 8.
The wheel cover attachment 8 introduced in the patent document 1 is composed of a retainer 9 made of a metal plate and a clip 10 made of a synthetic resin. Of these, the retainer 9 fits with the rim 4 of the disc wheel 1. The clip 10 is engaged with the peripheral portion of the attachment hole 14 a in the attachment portion 14 of the retainer 9 by the attachment leg 17 and the elastic engagement portion 18. The planar fastener portion 16 of the clip 10 engages with the planar fastener 21 of the wheel cover 7.
According to the technique introduced in Patent Document 1, metal-metal fitting between the disc wheel 1 and the retainer 9 and elastic-removable engagement between the metal-resin between the retainer 9 and the clip 10 are performed. The wheel cover 7 is attached to the disc wheel 1 through three steps, that is, the clip and the wheel cover 7 are detachably engaged between the resin and the resin by so-called surface fasteners.
According to such a method, although it is considered that the work of mounting the wheel cover 7 on the disc wheel 1 can be easily performed, the number of man-hours for the mounting work is very large, and the mounting strength of the wheel cover 7 on the disc wheel 1 is also high. It's hard to say enough.
Therefore, there is a demand for a technique capable of easily and stably attaching the wheel cover to the wheel.

Furthermore, a numerical value arbitrarily selected from these numerical ranges can be set as new upper and lower numerical values.

The wheel cover of the present invention is a wheel cover attached to the front side of a vehicle tire wheel. The front side here means the side of the tire wheel of the vehicle that is easily visible from the outside of the vehicle. The back side is the opposite side of the front side, and means the side of the tire wheel of the vehicle that is difficult to see from the outside of the vehicle. The same applies to the front and back surfaces.
Hereinafter, a wheel for a tire of a vehicle may be simply referred to as a wheel, if necessary. Further, hereinafter, the front side and the back side of the wheel cover of the present invention mean the front side and the back side of the wheel cover of the present invention attached to the wheel, and the front side and the back side mean the same direction as the front side and the back side of the wheel.

The wheel cover of the present invention has a cover body and a spacer body. Of these, the cover body is attached to the front side of the wheel and covers the surface of the wheel. Specifically, the cover body has a cover portion and an engaging portion. Of these, the cover portion is a portion that covers the surface of the wheel, and the engagement portion is a portion that is attached to the engagement hole of the wheel.
The engagement portion and the spacer body described later can be referred to as a two-part type attachment structure for attaching the cover portion to the wheel.
The surface of the cover part can also be said to be the design surface of the cover part.
The cover portion may cover the entire surface of the wheel or only a part of the surface of the wheel.

The engaging portion has two or more protruding pieces that are integrally provided on the cover portion.
Each protruding piece has a leg portion and a hook portion. The leg portion is a portion that is integrated with the back surface of the cover portion, and is also a portion that projects further to the back side from the back surface of the cover portion. The hook portion is a portion provided on a rear end portion of the leg portion, that is, a protruding end portion of the leg portion, and has a larger diameter than the leg portion.

  The leg portion may have any shape as long as it can project further to the back side from the back surface of the cover portion, and the leg portion may have a columnar shape, a plate shape, a rod shape, or the like. The length of the legs is not particularly limited, and the protruding direction of the legs is also not particularly limited. For example, the length of the leg portion in the direction from the front side to the back side may be shorter or longer than the length of the hook portion in the direction. The protruding direction of the legs may be parallel to the direction from the front side to the back side, or may be the direction intersecting the direction from the front side to the back side at an angle other than 90 °.

It can be said that the engaging portion has a portion formed of two or more leg portions and a portion formed of two or more hook portions. Of these, a portion formed of two or more leg portions is referred to as an engaging leg portion, and a portion of the engaging portion formed of two or more hook portions is referred to as an engaging hook portion. Since each of the protruding pieces described above protrudes from the back surface of the cover portion to the back side, it can be said that the engaging portion having these protruding pieces also protrudes from the back surface of the cover portion to the back side.
Further, the engaging leg portion is a portion integrated with the back surface of the cover portion, and the engaging hook portion can be said to be a portion having a larger diameter than the engaging leg portion provided at the back end of the engaging leg portion. .

The engaging portion is inserted into the engaging hole of the wheel. Therefore, when the wheel cover is attached to the wheel, at least a part of the engagement leg portion is arranged inside the engagement hole. Then, the back end of the engaging portion, that is, the engaging hook portion passes through the engaging hole and is exposed on the back side of the engaging hole.
Therefore, the engaging portion can engage with the peripheral portion of the engaging hole.

  The number of engaging portions provided on the wheel cover of the present invention is not particularly limited. Further, the wheel cover of the present invention may have a mounting structure for mounting the wheel cover on the wheel, in addition to the engaging portion. As the mounting structure, for example, a fixing surface for disposing an adhesive, a double-sided tape or the like can be mentioned.

The spacer body has a connecting portion, a first large diameter portion, and a second large diameter portion. The connecting portion extends from the front side to the back side. The first large diameter portion has a larger diameter than the connecting portion, and the second large diameter portion has a larger diameter than the connecting portion and the first large diameter portion. The first large diameter portion is provided at the back end of the connecting portion, and the second large diameter portion is provided at the front end of the connecting portion.
The extending direction of the connecting portion here is not limited to the direction parallel to the direction from the front side to the back side, but may be the direction intersecting the direction from the front side to the back side. The angle formed by the direction in which the connecting portion extends and the direction from the front side to the back side is preferably within the range of 0 ° ± 70 °, more preferably within the range of 0 ° ± 50 °, and 0 ° ± It is particularly preferable that it is in the range of 30 °. The closer the angle between the extending direction of the connecting portion and the direction from the front side to the back side is closer to 0 °, the smaller the engaging portion can be made, and the spacer body can be smoothly operated to attach the wheel cover to the wheel described later. There is an advantage that work can be performed easily and accurately.

  The spacer body is attached to the above-mentioned engaging portion. At this time, at least a part of the spacer body is arranged between the above-mentioned protruding pieces. Further, the spacer body can change its state relative to the engaging portion between the first state and the second state. In the first state, the connecting portion of the spacer body is arranged between the hook portions of the engaging portion, that is, inside the engaging hook portion, and the first large-diameter portion of the spacer body is arranged on the back side of the hook portion. To be done. In the second state, the first large-diameter portion of the spacer body is arranged between the hook portions of the engaging portion, that is, inside the engaging hook portion. In the first state, the distance between the hook portions is equal to or larger than the diameter of the connecting portion, and in the second state, the distance between the hook portions is equal to or larger than the diameter of the first large diameter portion, that is, the outer shape of the first large diameter portion. . Here, as described above, since the first large-diameter portion of the spacer body has a larger diameter than the connecting portion, when the spacer body is in the second state, compared to when the spacer body is in the first state, The space between the hook portions in the engaging portion is widened, and the engaging hook portion is in a diameter expanded state.

  In the wheel cover of the present invention, since the spacer body is in the second state when the wheel cover is attached to the wheel, the spacer body expands the engaging hook portion. As described above, when the engaging portion is inserted into the engaging hole of the wheel, the engaging hook portion is exposed on the back side of the engaging hole and is engageable with the peripheral portion of the engaging hole. Since the diameter is expanded by the body, it is stably engaged with the peripheral portion of the engagement hole.

  Further, in the wheel cover of the present invention, when the engaging portion is inserted into the engaging hole, the spacer body attached to the engaging portion is also inserted into the engaging hole together with the engaging portion, and the engaging hook portion is expanded. Make it diameter. Therefore, the work of attaching the wheel cover of the present invention to the wheel may be performed in one direction from the front side to the back side, and is completed in one operation. That is, the wheel cover of the present invention can be easily and stably attached to the wheel.

  Further, at this time, if the second large-diameter portion of the spacer body faces the surface of the wheel, the position change toward the back side of the second large-diameter portion, that is, the spacer body changes from the second state to the first state. State changes are interfered by the wheels. Therefore, in this case, the state in which the engagement hook portion and the peripheral edge portion of the engagement hole are engaged with each other is more stably maintained, and the wheel cover is more stably attached to the wheel.

Here, the mechanism that allows the spacer body to change its state relative to the engaging portion between the first state and the second state is not particularly limited.
For example, the engaging portion may be provided with a long groove, the spacer body may be provided with a protrusion that can be inserted or inserted into the long groove, and the protrusion of the spacer body may be slid in the long groove of the engaging portion. By doing so, the spacer body can change its position relative to the engaging portion along the direction in which the long groove extends. By appropriately providing a stopper that interferes with the protrusion in the long groove, the slide of the protrusion can be stopped in the first state and the second state, and thus the spacer body can be brought into the first state with respect to the engaging portion. It is possible to relatively change the state between the second state and the second state. The second large diameter portion of the spacer body may be used as the protrusion that is inserted into or inserted through the long groove.

  Alternatively, a through hole may be provided in the second large diameter portion of the spacer body, and the protruding piece may be inserted into the through hole. In this case, since the spacer body is slidable along the protruding direction of the projecting piece, similarly to the above, the spacer body is relatively moved with respect to the engaging portion between the first state and the second state. It is possible to change the state.

Alternatively, a guide portion that guides the sliding direction of the spacer body may be provided in addition to the spacer body and the engaging portion, and the change in the state of the spacer body may be guided by the guide portion.
The direction in which the state of the spacer body changes is not particularly limited, and the state of the spacer body may change linearly or may change in a curved state.

  The material of the wheel cover of the present invention is not particularly limited, but in consideration of weight reduction and material cost reduction, it is preferable to use a resin material for at least the cover body. Further, in consideration of the behavior of the engaging portion described later, the engaging portion needs to be deformable, and is preferably elastically deformable. Therefore, a resin material or a metal such as spring steel is used for the engagement. Is preferred. Considering the role of the spacer body, it is preferable to use a material having high rigidity equal to or higher than that of the engaging portion of the cover body.

  It can be said that the wheel cover of the present invention can be expanded / contracted by the spacer member as described above by using the one having two or more protruding pieces as the engaging portion. In the wheel cover of the present invention, the number of protruding pieces included in one engaging portion is not particularly limited, but it is preferable that the number is not excessive in consideration of operational stability and manufacturing cost. Specifically, it is preferable that the number of the protruding pieces included in one engaging portion is about 2 to 5. The hook portion preferably has an engagement surface that engages with a peripheral edge portion of the engagement hole on the back surface of the wheel when the wheel cover is attached to the wheel.

  The engagement surface is preferably arranged on the front side of the portion having the maximum diameter in the hook portion (referred to as the maximum diameter portion). The hook portion preferably has a head portion having a smaller diameter than the maximum diameter portion on the back side of the maximum diameter portion. By providing such a head portion, there is an advantage that the engaging portion can be easily inserted into the engaging hole and the work of attaching the wheel cover to the wheel becomes easier. In addition, it is preferable that the head has an inclined surface that is inclined from the outer side and the front side of the engaging portion toward the inner side and the back side of the engaging portion. If the head has such a shape, when the engaging portion is inserted into the engaging hole, the engaging hook portion that abuts on the peripheral portion of the engaging hole in the wheel is naturally reduced in diameter to engage the engaging portion. The part is easily inserted into the engagement hole.

  In addition, in the wheel cover of the present invention, the hook portion may be composed of the maximum diameter portion as a whole, or may not have the engaging surface. Also in this case, as described above, there is no change in the point that the spacer body stably attaches the engaging portion to the peripheral edge portion of the engaging hole in the wheel.

  Hereinafter, the wheel cover of the present invention will be described with reference to specific examples.

As shown in FIGS. 5 and 7, the first large diameter portion 51 and the second large diameter portion 52 have a plate shape extending in a direction substantially orthogonal to the connecting portion 50. The outer diameter of the first large diameter portion 51 is larger than the outer diameter of the connecting portion 50. Therefore, it can be said that the first large diameter portion 51 has a larger diameter than the connecting portion 50. The length of the second large diameter portion 52 in the longitudinal direction is longer than the outer diameter of the connecting portion 50 and the outer diameter of the first large diameter portion 51. Therefore, it can be said that the second large diameter portion 52 has a larger diameter than the connecting portion 50 and the first large diameter portion 51. The outer diameter of the first large-diameter portion 51 herein may be rephrased as the length of the first large-diameter portion 51 in the direction in which the two protruding pieces 31 face each other.
The first large diameter portion 51 is provided at the back end of the connecting portion 50, and the second large diameter portion 52 is provided at the front end of the connecting portion 50.

  The spacer body 5 is attached to the engaging portion 30. Specifically, one end of the second large diameter portion 52 of the spacer body 5 is inserted into the long groove 43a of the one protruding piece 31a shown in FIG. The other end of the diameter portion 52 is inserted into the groove opening 43b of the other protruding piece 31b. By inserting the other end of the second large diameter portion 52 into the long groove 43a through the groove opening 43b, both ends of the second large diameter portion 52 are inserted into the long grooves 43a of the different protruding pieces 31a and 31b. As it is, the second large diameter portion 52 is slid to the back side end portion of the long groove 43a, and the first large diameter portion 51 is placed on the back side of the engaging portion 30, more specifically on the back side of the hook portion 33 of each protruding piece 31. By positioning it, the spacer body 5 is brought into the first state shown in FIG. At this time, the connecting portion 50 of the spacer body 5 is arranged between the hook portions 33 of the two protruding pieces 31. In other words, at this time, the connecting portion 50 is arranged inside the engaging portion 30, inside the engaging hook portion 41 and inside the engaging leg portion 47. The engaging hook portion 41 is a portion of the engaging portion 30 that is formed by the hook portions 33 of the two protruding pieces 31. The engaging leg portion 47 is a portion of the engaging portion 30 that is constituted by the leg portions 32 of the two protruding pieces 31.

  The spacer body 5 attached to the engaging portion 30 can change its state between the first state shown in FIG. 3 and the second state shown in FIG. When the state of the spacer body 5 in the first state shown in FIG. 3 is changed toward the front side, the second large diameter portion 52 slides the long groove 43a shown in FIG. 5 to the front side end portion, and the first large diameter portion 51. Enters between the hook portions 33 of the two protruding pieces 31. Then, as shown in FIG. 5, the inner rib portions 40 provided on the hook portions 33 of the respective protruding pieces 31 come into contact with both end portions of the first large diameter portion 51 in the longitudinal direction.

  Hereinafter, the behavior of each part of the wheel cover 1 of the embodiment when mounted on the wheel will be described.

  When the wheel cover 1 of the embodiment is attached to the aluminum wheel 9, first, the spacer body 5 is brought into the first state shown in FIG. At this time, since the small-diameter connecting portion 50 is arranged between the hook portions 33 of the two protruding pieces 31, the protruding pieces 31 can change their positions in the approaching direction, and a part of the protruding pieces 31 can be moved. The positions of the hook portions 33, which are the same, can also be changed in the direction of approaching each other. Therefore, at this time, the engagement hook portion 41 of the engagement portion 30 can be reduced in diameter.

  The wheel cover 1 in this state is applied to the front side of the al wheel 9 (see FIG. 7) so that the engaging portion 30 is located on the front side of the engaging hole 91 (see FIG. 7), and is pressed toward the rear side, that is, the aluminum wheel 9. Then, the peripheral edge portion 91a of the engagement hole 91 on the surface of the aluminum wheel 9 relatively presses the first inclined surface 37 of each hook portion 33. As shown in FIG. 7, the engaging portion 30 has a larger diameter than the engaging hole 91 at this time. However, since the first inclined surface 37 is an inclined surface that is inclined from the outside and front side of the engaging portion 30 toward the inside and rear side of the engaging portion 30, each hook portion 33 has a peripheral edge portion of the engaging hole 91. The positions are changed by being pressed by 91a and approaching each other, that is, toward the inside of the engaging portion 30. That is, at this time, the engagement portion 30 has a reduced diameter and can be inserted into the engagement hole 91 (see FIG. 8). At this time, when the connecting portion 50 of the spacer body 5 is arranged inside the engaging portion 30, since the connecting portion 50 has the tapered tapered connecting portion 53 having a smaller diameter toward the front side. The hook portion 33 of the protruding piece 31 is also guided by the taper-shaped connecting portion 53 and gradually changes in the direction toward each other, that is, toward the inside of the engaging portion 30.

  When the position of the wheel cover 1 is changed to the first intermediate position shown in FIG. 8, the second large diameter portion 52 comes into contact with the peripheral edge portion 91a of the engaging hole 91 on the surface of the aluminum wheel 9, and the spacer body 5 is further moved. The position cannot be changed on the back side. Therefore, when the wheel cover 1 is pressed further from the first intermediate position shown in FIG. 8 toward the back side, as shown in FIG. 9, the position of the spacer body 5 remains the same and only the engaging portion 30 moves toward the back side. The position changes. That is, at this time, the spacer body 5 starts a relative state change from the first state to the second state.

When the wheel cover 1 is pressed further toward the back side from the second intermediate position shown in FIG. 9, the hook portion 33 is exposed to the back side of the engagement hole 91. Then, as shown in FIG. 10, the restricting force of the aluminum wheel 9 on the hook portion 33 is released, and the hook portions 33 are allowed to change their states in a direction away from each other, that is, in the outward direction of the engaging portion 30.
At this time, as shown in FIG. 10, the first large diameter portion 51 of the spacer body 5 is arranged between the hook portions 33. Therefore, the distance between the hook portions 33 is widened by at least the length corresponding to the diameter of the first large diameter portion 51. Therefore, when the spacer body 5 changes to the second state shown in FIG. 10, the outer diameter of the engaging hook portion 41 becomes larger than the hole diameter of the engaging hole 91. At this time, since the engaging hook portion 41 passes through the engaging hole 91 and is exposed on the back side of the aluminum wheel 9, the engaging hook portion 41 engages with the peripheral edge portion 91b of the engaging hole 91 on the back surface of the aluminum wheel. Since the engagement surface 35 of the engagement hook portion 41 is in surface contact with the peripheral edge portion 91b, it can be said that the engagement portion 30 is stably engaged with the peripheral edge portion 91b of the engagement hole 91.

  Further, in the second state shown in FIG. 10, the second large diameter portion 52 faces the surface of the aluminum wheel 9, and the second large diameter portion 52 interferes with the surface of the aluminum wheel 9 and cannot largely change its position to the back side. Therefore, the spacer body 5 is also kept in the second state and cannot change to the first state. As a result, the first large diameter portion 51 of the spacer body 5 is stably retained between the hook portions 33, and the engagement portion 30 is stably engaged with the peripheral edge portion 91b of the engagement hole 91.

As shown in FIG. 11, when the wheel cover 1 and the aluminum wheel 9 are attached, the dimensions of each part of the wheel cover 1 of the embodiment in which the spacer body 5 is in the second state are from the first state to the second state. Of the position change amount M1 of the first large diameter portion 51 in the direction from the front side to the back side when changing the state to the state, and the maximum distance L1 between the second large diameter portion 52 and the surface of the aluminum wheel 9 in the second state. The relationship is designed to satisfy L1 <M1.
As a result, in the mounted state, the spacer body 5 cannot change its state from the second state to the first state, and the first large-diameter portion 51 of the spacer body 5 is more stably retained between the hook portions 33, and The joint portion 30 is stably engaged with the peripheral edge portion 91b of the engagement hole 91.

  Further, in the wheel cover 1 of the embodiment, the spacer body 5 can be changed to the third state in which the spacer body 5 is arranged further on the front side than the second state. In the wheel cover 1 of the embodiment, in the third state, the surface of the second large diameter portion 52 contacts the back surface 21b of the mounting seat 21 of the cover portion 20. Therefore, when a large external force is applied to the spacer body 5 in the second state toward the front side, the spacer body 5 may change from the second state to the third state. However, in the wheel cover 1 of the embodiment, even when the spacer body 5 is in the third state, the first large diameter portion 51 of the spacer body 5 is in a state of being sandwiched by the projecting pieces 31, and the engaging portion 30 is slightly different. Although the diameter is reduced, the expanded state of the engagement portion 30 by the first large diameter portion 51 is still maintained. Therefore, the diameter of the engaging portion 30 does not decrease to such an extent that the engaging portion 30 can pass through the engaging hole 91, and the engaging portion 30 is more stably engaged with the peripheral edge portion 91b of the engaging hole 91.

  In the wheel cover 1 of the embodiment, since the engaging portion 30 is composed of the two protruding pieces 31, the shape of the first large-diameter portion 51 is such that the two hook portions 33 are spaced at both ends in the longitudinal direction in the second state. The shape of the second large-diameter portion 52 is a plate shape that can be pressed in the direction in which the first large-diameter portion 51 and the second large-diameter portion 52 are formed. Is not limited to this. For example, when the engaging portion 30 is composed of four protruding pieces 31, the first large diameter portion 51 may have a circular plate shape or a block shape, and the second large diameter portion 52 may have a cross shape. good.

  The present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications without departing from the scope of the invention. Moreover, each component shown in this specification including embodiment can be extracted arbitrarily, and combined and implemented.
