Description

  The present invention relates to a clip and a mounting structure using the clip.

  For example, when installing a door mirror on the front door of a vehicle such as an automobile, it is called a substantially triangular patch of the door mirror against a base support member called an aluminum die-cast cast molding provided on the window frame of the front door. The mirror base is attached using a clip. A conventional example of an attachment structure for attaching a mirror base to the base support member using a clip will be described. FIG. 11 is a cross-sectional view showing a mounting structure using a clip according to a conventional example.

  As shown in FIG. 11, a mounting hole 111 is formed in the base support member 110. In addition, a channel-shaped clip mounting portion 123 is formed on the back side of the mirror base 120. The clip 140 includes an attachment shaft portion 141 that slides in the opening groove portion 123a of the clip attachment portion 123 of the mirror base 120, a flange portion 142 that is engaged in the clip attachment portion 123 and prevents the clip 140 from being removed, and a base support. It has a locking portion 143 whose cross section that elastically engages with the mounting hole 111 of the member 110 has an S-shape, and a skirt-shaped pressing portion 144 that elastically contacts the base support member 110. The clip 140 is fixedly attached to the mirror base 120 by sliding the mounting shaft portion 141 into the opening groove portion 123a of the clip mounting portion 123 of the mirror base 120 and engaging the flange portion 142 in the clip mounting portion 123. It is done. Then, the engaging portion 143 of the clip 140 is elastically engaged in the mounting hole 111 of the base support member 110, and the pressing portion 144 elastically contacts the base support member 110, so that the base support member 110 is brought into contact. The mirror base 120 is attached in a non-removable state. In addition, the attachment structure using such a clip 140 is described in patent document 1, for example.

  By the way, depending on the vehicle type, there is a case where it is desired to set a gap (this gap is referred to as “mounting gap”) S1 between the base support member 110 and the mirror base 120 to be small. However, the mounting structure using the clip 140 (see FIG. 11) has a problem that it is difficult to reduce the mounting gap S1 because the clip mounting portion 123 needs to be provided on the mirror base 120.

  The problem to be solved by the present invention is to provide a clip and a mounting structure using the clip that can reduce the mounting gap between the mounting member and the mounted member.

The above-described problems can be solved by a clip having a configuration described in the claims and a mounting structure using the clip.
That is, the clip concerning Claim 1 of a claim is a clip which attaches the to-be-attached member which has the attachment convex part corresponding to the said attachment hole with respect to the attachment member which has an attachment hole. A clip main body formed so as to be able to be fitted in a mounting hole of the mounting member; an engagement recess provided in the clip main body and externally fitted to a mounting convex of the mounted member; and the clip main body And a retaining portion that is provided on at least one of the two side portions and engages with the mounting hole of the mounting member. Forming the outer side surfaces of both side wall portions facing the engagement recesses in the direction intersecting the direction extending to the both side portions of the clip main body portion so as to be close to or abutting the inner side surface of the mounting hole; The bending deformation in the opposing direction of the both side walls is configured to be restricted by the mounting convex part engaged in the engaging concave part. If comprised in this way, a clip main-body part will be fitted in the attachment hole of an attachment member in the state which engaged the attachment convex part of the to-be-attached member in the engagement recessed part of the clip main-body part. Thereby, the relative bending deformation to the opposing direction of the both-sides wall part of a clip main-body part is controlled by the attachment convex part of a to-be-attached member. Further, in this state, the clip main body portion is prevented from being pulled out by engaging the retaining portion in the mounting hole of the mounting member. As a result, the outer side surfaces of the side wall portions of the clip main body portion approach or abut on the inner side surface of the mounting hole. In this way, the member to be attached is attached to the attachment member using the clip. Therefore, according to the present clip, since it is not necessary to form a clip mounting portion that has been conventionally required on the mounting member, the mounting gap between the mounting member and the mounted member can be reduced. In addition, in the attachment state of the member to be attached to the attachment member, the outer side surfaces of the side wall portions of the clip body portion are close to or abutting the inner side surface of the attachment hole of the attachment member, and the opposite side walls are relatively opposed to each other. Therefore, it is possible to prevent or reduce the rattling of the clip in the direction intersecting the direction extending to both sides of the clip main body with respect to the mounting hole of the mounting member. it can.

  Further, in the mounting structure using the clip according to claim 2 of the claims, the mounted member having the mounting convex portion corresponding to the mounting hole is attached to the mounting member having the mounting hole. It is attached with the described clip. If comprised in this way, the attachment structure using the clip which can reduce the attachment clearance gap between an attachment member and a to-be-attached member can be provided.

  Next, the best mode for carrying out the present invention will be described with reference to examples.

  An embodiment of the present invention will be described. In this embodiment, when installing a door mirror on the front door of a vehicle such as an automobile, an attachment structure using a clip for attaching the mirror base of the door mirror to the base support member provided on the window frame of the front door using a clip It illustrates about. 1 is a front sectional view showing a mounting structure using a clip, FIG. 2 is a sectional view taken along the line II-II in FIG. 1, and FIG. 3 is an exploded perspective view showing components relating to the mounting structure using a clip. It is. Hereinafter, the base support member 10, the mirror base 20, and the clip 30 will be described in this order.

  First, the base support member 10 will be described. As shown in FIG. 3, the base support member 10 is a cast molding made of, for example, aluminum die cast, and is provided on a window frame of a front door of a vehicle such as an automobile (not shown). A rectangular attachment hole 11 is formed in the plate-like portion 10 a of the base support member 10. For convenience of explanation, the longitudinal direction (left-right direction in FIG. 1) of the mounting hole 11 of the base support member 10 will be described as the left-right direction, and the short direction (left-right direction in FIG. 2) will be described as the front-rear direction. The base support member corresponds to an “attachment member” in this specification.

  Next, the mirror base 20 will be described. As shown in FIG. 3, the mirror base 20 is made of, for example, resin and has a plate-like portion 20 a that is superposed on the base support member 10. A mounting boss portion 21 having a rectangular parallelepiped shape protrudes vertically on the back side of the plate-like portion 20a of the mirror base 20 (the side facing the base support member 10). The mounting boss portion 21 corresponds to the central portion of the mounting hole 11 of the base support member 10 and is formed with the longitudinal direction of the cross section as the left-right direction and the short side direction as the front-rear direction. A locking claw 22 extending in the left-right direction is formed on the lower end portion of the mounting boss portion 21, that is, the front side surface of the distal end portion. The locking claw 22 includes a locking surface 22a that is parallel to the mirror base 20, and an inclined surface 22b that gradually decreases the amount of protrusion with respect to the front side surface of the mounting boss portion 21 from the front end edge of the locking surface 22a downward. Have. The mounting boss portion 21 corresponds to the “mounting convex portion” referred to in this specification. The mirror base 20 corresponds to a “attached member” in this specification.

Next, the clip 30 will be described. As shown in FIG. 3, the clip 30 is made of, for example, a resin integrally molded product. 4 is a front view showing the clip, FIG. 5 is a side view, FIG. 6 is a cross-sectional view taken along line VI-VI in FIG. 4, FIG. 7 is a bottom view showing the clip, and FIG. .
The clip main body 31 constituting the main body of the clip 30 includes a long square plate-like front side wall portion 32, a long square plate-like rear side wall portion 33 parallel to the front side wall portion 32, a front side wall portion 32, and a rear side. It has a long rectangular plate-like lower side wall part 34 that connects the lower end part with the side wall part 33. The clip main body 31 is formed so as to be fitted in the mounting hole 11 of the base support member 10 (see FIGS. 1 and 2). Therefore, the width of the clip body 31 in the front-rear direction (the width in the left-right direction in FIG. 5) is equal to or slightly the same as the hole width in the front-rear direction of the mounting hole 11 of the base support member 10 (the width in the left-right direction in FIG. 2). It is set to a small dimension. For this reason, when the clip main-body part 31 is fitted in the attachment hole 11, both side wall parts 32 and 33 adjoin or contact | abut to the inner surface before and behind the said attachment hole 11 (refer FIG. 2). Moreover, the front side wall part 32 is formed with a thin wall thickness compared with the wall thickness of the rear side wall part 33, and is formed so as to be able to bend forward and deform (see the two-dot chain line 32 in FIG. 6). Moreover, the bottomed recessed part between the front side wall part 32 and the rear side wall part 33 is the engagement recessed part 35 (refer FIG. 6). The width in the front-rear direction of the engagement recess 35 (the width in the left-right direction in FIG. 6) is approximately equal to the thickness in the front-rear direction of the mounting boss portion 21 of the mirror base 20 (thickness in the left-right direction in FIG. 2). Is set. For this reason, the mounting boss portion 21 can be fitted into the engaging recess 35 using the bending deformation of the front side wall portion 32 (see the two-dot chain line 32 in FIG. 6), and the opposing directions of the side wall portions 32 and 33 are opposed to each other. The mounting boss portion 21 is formed so as to be able to regulate relative bending deformation to (see FIG. 2). Thus, a rectangular locking hole 36 is opened at the lower end of the front side wall 32 (see FIGS. 3, 6, and 8). The locking hole 36 is formed so as to be able to engage with the locking claw 22 of the mounting boss portion 21 (see FIGS. 1 and 2).

  As shown in FIG. 4, a pair of left and right locking legs 38 that protrude outwardly from the left and right ends of the lower wall 34 of the clip main body 31 are projected. Both locking legs 38 are formed with a width in the front-rear direction (width in the left-right direction in FIG. 5) equal to the width in the front-rear direction (the width in the left-right direction in FIG. 6) of the clip main body 31. Both the locking leg portions 38 are formed so as to be able to bend and deform toward the clip main body portion 31 side (see a two-dot chain line 38 in FIG. 4). A stepped locking step edge 38a extending in the front-rear direction is formed on the outer side of the distal end portion (upper end portion) of both the locking leg portions 38 (see FIG. 4). The locking step edge 38a can be engaged with the left and right inner edges of the mounting hole 11 of the base support member 10 by utilizing the bending deformation of both locking legs 38 (refer to the two-dot chain line 38 in FIG. 4). It is formed (see FIG. 1). The locking leg portion 38 corresponds to a “prevention portion” in the present specification.

Next, a procedure for attaching the mirror base 20 to the base support member 10 will be described. 9 is a front sectional view showing a state in which the clip is attached to the mirror base, and FIG. 10 is a sectional view taken along line XX in FIG.
First, as shown in FIGS. 9 and 10, the clip 30 is attached to the mounting boss portion 21 of the mirror base 20. That is, the mounting boss portion 21 of the mirror base 20 is relatively fitted into the engagement recess 35 (see FIG. 6) of the clip main body portion 31. At this time, the inclined surface 22b of the locking claw 22 of the mounting boss portion 21 comes into contact with and slides on the front side wall portion 32 of the clip main body portion 31, so that the front side wall portion 32 is bent and deformed. (See the two-dot chain line 32 in FIG. 6). And when the front-end | tip part (lower end part) of the attachment boss | hub part 21 contact | abuts or adjoins the lower side wall part 34, when the latching claw 22 and the latching hole 36 respond | correspond, the front side wall part 32 of the clip main-body part 31 will be. The elastic claw 22 of the mounting boss 21 is engaged with the locking hole 36 of the front side wall 32. As a result, when the locking surface 22 a of the locking claw 22 and the inner surface on the upper side of the locking hole 36 face each other, the clip main body portion 31 is prevented from being pulled out by the mounting boss portion 21. Further, the left and right side surfaces of the locking claw 22 and the left and right inner surfaces of the locking hole 36 face each other, whereby the clip main body portion 31 is positioned with respect to the mounting boss portion 21 in the left-right direction (left-right direction in FIG. 9). Is done. Further, when the front end surface (lower end surface) of the mounting boss portion 21 and the upper surface of the lower side wall portion 34 face each other, the fitting amount of the clip main body portion 31 with respect to the mounting boss portion 21 is defined (see FIG. 10). . Thereby, relative bending deformation in the opposing direction of the side wall portions 32 and 33 of the clip main body portion 31 is restricted by the mounting boss portion 21 of the base support member 10.

  Subsequently, the clip 30 (see FIGS. 9 and 10) attached to the mirror base 20 is pressed into the attachment hole 11 of the base support member 10. At this time, both the locking leg portions 38 of the clip 30 are in contact with the left and right inner edges of the mounting hole 11 and slide to bend and deform toward the clip main body portion 31 side (in FIG. (See dotted line 38). When the locking step edges 38a of the both locking leg portions 38 pass through the mounting holes 11, the both locking leg portions 38 are elastically restored, so that the locking step edges 38a of the both locking leg portions 38 become the mounting holes. 11 (see FIG. 1). As a result, the clip 30 is prevented from being removed from the base support member 10. Further, the outer side surfaces of the side wall portions 32 and 33 of the clip main body portion 31 are close to or abut on both the front and rear inner side surfaces of the mounting hole 11 (see FIG. 10). As described above, the mirror base 20 is attached to the base support member 10 using the clip 30. An elastic member such as a gasket or sponge material (not shown) is interposed between the base support member 10 and the mirror base 20.

  According to the clip 30 described above, since it is not necessary to form a clip mounting portion conventionally required on the mirror base 20, the mounting gap S between the base support member 10 and the mirror base 20 (see FIGS. 1 and 2). .) Can be reduced. In addition, when the mirror base 20 is attached to the base support member 10, the outer surfaces of the front and rear side walls 32 and 33 of the clip main body 31 are close to or abut on the front and rear inner surfaces of the attachment hole 11 of the base support member 10. The relative deformation in the opposing direction of the side wall portions 32 and 33 is restricted by the mounting boss portion 21 of the mirror base 20 (see FIG. 2). Therefore, rattling of the clip 30 in the front-rear direction (left-right direction in FIG. 2), which is the direction in which both side portions of the clip main body 31 extend with respect to the mounting hole 11 of the base support member 10, that is, the direction intersecting the left-right direction, is prevented. Alternatively, it can be reduced.

  Moreover, according to the attachment structure using the clip 30, an attachment structure using the clip 30 that can reduce the attachment gap S between the base support member 10 and the mirror base 20 can be provided (FIG. 1). And FIG. 2).
