The clip comprises: a pair of leg piece parts (11a, 11b) adapted to be elastically rotated and entered into a back side of the edge part facing the fixing hole; a pair of holding parts (12a, 12b) into which the edge parts of the fixing hole of a corresponding side are inserted by cooperating with the leg piece part of the corresponding side; a pair of pinching parts (13a, 13b) hooked to fit in the rib to pinch the rib; and a head part (15) connected to the pair of pinching parts, wherein the head part is formed to have lower stiffness than the pair of pinching parts.

Description

Clip {CLIP}

In order to detachably attach an attachment member protruding from a surface of a rib to a member to be attached having an attachment hole, the edge portion of the attachment hole is fixed to the surface of the attachment hole by engaging with the rib Shaped clip adapted to be inserted into the clip.

For example, it has been well known that a center cluster or the like is detachably mounted on an instrument panel of an automobile. In order to detachably attach the attachment member protruding from the surface of the rib to the attachment object having the attachment hole, the edge portion of the attachment hole and the surface of the attachment hole, A U-shaped clip fixed to the side of the clip is well known.

Concretely, for example, such a clip is disclosed in Patent Document 1. In particular, FIG. 6 of Patent Document 1 discloses a clip that realizes a high foot force (a pulling force: difficult to fall). For illustrative purposes, the drawings are referred to herein as FIG.

The clip 50 shown in Fig. 6 includes a pair of leg piece portions 66 that are configured to be elastically rotated to the back side of the opposing edge portion of the attachment hole (not shown), and a pair of leg piece portions 66 A pair of engaging portions 64 which cooperate with each other so as to engage the edge portion of the mounting hole of the corresponding side and a pair of engaging portions 64 which engage with the ribs to sandwich a rib (not shown) A pair of holding portions 56 to be aligned with each other, and a head portion 52 connecting the pair of holding portions.

The head portion 52 is formed in a trapezoidal shape inside the pair of holding portions 56 when viewed from the side. In this clip 50, the pair of holding portions 56 is elongated so as to be sufficiently deformed. The rigidity of the head portion 52 is higher than the rigidity of the pair of holding portions 56. [

The pair of holding portions 56 is not formed by a region from the pair of latching portions 64 to the head portion 52 but is formed by a pair of latching portions 64, (Not shown).

The clip 50 shown in Fig. 6 has the same shape (section) in the direction perpendicular to the paper surface of Fig. 6 because it is generally formed by the front side mold and the rear side mold with respect to the paper surface of Fig. 6 .

Such a clip 50 is capable of realizing a pumping force by a pair of holding portions 56 having a sufficient thickness while being elongated such that the pair of holding portions 56 can be sufficiently bent and deformed. There is an advantage that the insertion force of the poem is also low.

Patent Document 1: JP-A-10-54411

However, in the above-described clip 50, it is necessary to form a long length so that the pair of gripping portions 56 can be sufficiently deformed in order to keep the insertion force at the time of mounting low. Therefore, there is a drawback that the whole clip can not be made compact. In addition, since the lower ends of the pair of holding portions 56 are at low positions, the degree of freedom of the metal mold of the attaching member is small from the viewpoint of slide clearance (see Fig. 4).

The present invention is based on the above knowledge. An object of the present invention is to provide a clip capable of realizing a high embossing force and a low insertion force while allowing the entire clip to be compact and capable of sufficiently increasing the degree of freedom of a metal mold of the attaching member.

In order to detachably attach an attachment member protruding from a surface of a rib to a member to be attached having an attachment hole, the edge portion of the attachment hole is fixed to the surface of the attachment hole by engaging with the rib Wherein the U-shaped clip is provided with a pair of leg piece portions which are adapted to be elastically turned back to the back side of the opposing edge portion of the attaching hole, A pair of latching portions adapted to engage with the edge portions; a pair of holding portions adapted to engage with the ribs to hold the ribs; and a head portion connecting the pair of holding portions, And the portion is formed to have a lower stiffness than the pair of holding portions.

According to the present invention, since the head portion is formed to have a lower rigidity than the pair of grip portions, even when a pair of grip portions are formed to have a sufficient thickness for realizing the high grip force, the insertion force at the time of mounting can be remarkably reduced have. In addition, since it is not necessary to form a pair of holding portions long, the whole clip can be made compact, and the degree of freedom of the metal mold of the attaching member can be made sufficiently large.

As a specific example in which the head portion is formed to have lower rigidity than the pair of grip portions, for example, a configuration in which the head portion is formed so as to protrude outward beyond the pair of grip portions can be cited. For example, the head portion may be formed in the shape of a long circle laterally when viewed from the side. In order to realize a further lower rigidity, there are cases in which the width is narrowed, a case where a notched hole is formed in the head portion, and the hinge portion is separated into two hinge portions. Alternatively, the head portion may be formed to be thinner than the pair of grip portions, for example, as a specific form when the head portion is formed to have a lower rigidity than the pair of grip portions. For example, the head portion may be formed to have a thickness half that of the pair of holding portions.

In the case where the rib has the engaging hole, a pair of engaging protrusions is formed in the pair of engaging portions so as to engage with the engaging holes formed in the ribs.

In this case, it is preferable that the pair of engaging pawls is formed in a positional relationship not opposed to each other on the opposing inner side faces of the pair of gripping portions. When a pair of engaging ridges is formed by such a positional relationship, there is an advantage in the strength of the mold when it is produced by molding using a metal mold.

It is preferable that the pair of engaging pawls are arranged such that the releasing force transmitted from the pair of engaging portions to the pair of gripping portions acts in a direction to narrow the pair of engaging protrusions. With this arrangement, a higher footing force can be realized.

According to the present invention, since the head portion is formed to have a lower rigidity than the pair of grip portions, even when a pair of grip portions are formed to have a sufficient thickness for realizing the high grip force, the insertion force at the time of mounting can be remarkably reduced have. Further, since it is not necessary to form a pair of holding portions long, the entire clip can be made compact, and the degree of freedom of the metal mold of the attaching member can be made sufficiently large.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic perspective view of a clip according to an embodiment of the present invention. Fig. 2 is a schematic front view of the clip of Fig. 1 attached to an attachment hole. Fig. Figure 3 is a schematic perspective view of the clip of Figure 1 attached to the clip tower 20;

As shown in Figs. 1 and 2, the clip 10 of the present embodiment has a structure in which the attachment member having the attachment hole 30 is detachably attached to the attachment member, And is fixed to the front surface side of the attachment hole 30 by engaging with the edge portions 31a and 31b of the attachment hole 30 and the rib 35. [

The clip 10 of the present embodiment includes a pair of leg piece portions 11a and 11b which are configured to be elastically retracted toward the back side of the opposite edge portions 31a and 31b of the attachment hole 30, And a pair of engaging portions 12a and 12b which cooperate with the corresponding leg portions 11a and 11b to fit the edge portions 31a and 31b of the corresponding attaching hole, A pair of gripping portions 13a and 13b adapted to be engaged with the ribs 35 so as to hold the grip portions 35 and 35 and a head portion 15 connecting the pair of gripping portions 13a and 13b.

As shown in Figs. 1 and 2, the head portion 15 of the present embodiment is formed in the shape of a long, long side when viewed from the side. As a result, the pair of holding portions 13a, And has a lower rigidity than that of the first embodiment. As shown in Fig. 3, this shape has an advantage that the attachment length can be increased when attached to the clip tower 20.

The clip 10 of the present embodiment corresponds to the case where the rib 35 has the engagement hole and the clip 10 is provided with the pair of gripping portions 13a and 13b in the engagement hole formed in the rib 35 And a pair of engaging ridges 14a and 14b to be engaged are formed. In the present embodiment, two ridges 14p capable of contacting the ribs 35 are formed on the upper sides of the pair of engagement ridges 14a and 14b, respectively.

The pair of engaging protrusions 14a and 14b of this embodiment is formed on the inner surface of the opposite pair of gripping portions 13a and 13b as in the case of a conventional clip, But are formed in a positional relationship (mutual positional relationship) that do not face each other. This has the advantage that the strength of the mold can be increased when the clip 10 of the present embodiment is formed by the front side mold and the rear side mold.

In practice, the clip 10 of the present embodiment is formed by the front side mold and the rear side mold, and thus has the same shape (section) in the longitudinal direction except for a pair of engaging protrusions 14a and 14b have.

In this embodiment, the pair of gripping portions 13a and 13b are formed by a region between the pair of engaging portions 12a and 12b to the head portion 15, The engaging ridges 14a and 14b are arranged on a substantially extending line extending from the pair of engaging portions 12a and 12b to the pair of gripping portions 13a and 13b. With this arrangement, the pair of engaging protrusions 14a and 14b are bent when the clip 10 is inserted, while the releasing load (releasing force) is applied to the pair of engaging portions 12a and 12b And is transmitted toward the pair of holding portions 13a, 13b, whereby the releasing load acts in a direction to narrow the pair of engaging protrusions 14a, 14b.

According to the present embodiment as described above, since the head portion 15 is formed to have lower rigidity than the pair of grip portions 13a and 13b, the pair of grip portions 13a and 13b It is possible to remarkably lower the insertion force at the time of mounting even when formed into a thickness. Further, since it is not necessary to form the pair of holding portions 13a and 13b long, the entire clip can be made compact, and as shown in Fig. 4, the degree of freedom of the metal mold of the attaching member can be made sufficiently large can do.

The pair of engaging protrusions 14a and 14b are arranged on the approximately extended line extending from the pair of engaging portions 12a and 12b to the pair of gripping portions 13a and 13b, The pressing force transmitted to the pair of gripping portions 13a and 13b at the portions 12a and 12b acts in the direction to narrow the pair of engaging protrusions 14a and 14b so that a higher pressing force can be realized.

In the above-described embodiment, the head portion 15 is formed to have the same shape as a long side when seen from the side, but it is not limited to such a shape at the time of filing of the present application at least. The head portion 15 is formed to have a lower rigidity than the pair of grip portions 13a and 13b even if the head portion 15 is formed in any other shape so as to protrude outward than the pair of grip portions 13a and 13b It is possible to do. It is also possible to form the head portion 15 thinner than the pair of holding portions 13a and 13b so that the head portion 15 has a lower rigidity than the pair of holding portions 13a and 13b.

In order to realize a lower rigidity, a notched hole may be formed in the head portion 15 as shown in Fig. 5, a notch hole is formed in the central region of the head portion 15 so as to extend from one holding portion 13a to the other holding portion 13b, Are separated into two hinge portions. According to this configuration, even lower rigidity can be realized.
