Description

  The present invention relates to the mounting hole by engaging the edge of the mounting hole and the rib in order to detachably mount the mounting member having the rib protruding to the front side with respect to the mounted member having the mounting hole. The present invention relates to a substantially U-shaped clip that is fixed to the front side.

  For example, it has been well known to detachably attach a center cluster or the like to an instrument panel of an automobile. As such a detachable mounting structure, in order to detachably mount a mounting member having a rib protruding to the front side with respect to a mounted member having a mounting hole, it engages with an edge of the mounting hole and the rib. Thus, a generally U-shaped clip that is fixed to the front side of the mounting hole is well known.

  Specifically, for example, Patent Document 1 discloses such a clip. In particular, FIG. 6 of Patent Document 1 discloses a clip that realizes a high removal force (that is, it is difficult to come off). For illustrative purposes, this drawing is referred to as FIG. 6 of the present application.

  The clip 50 shown in FIG. 6 cooperates with a pair of leg pieces 66 that are elastically wound around the opposite side of the opposite edge of the mounting hole (not shown) and the leg piece 66 on the corresponding side. A pair of latching portions 64 that sandwich the edge of the mounting hole on the corresponding side, and a pair of sandwiching portions that engage with the rib (not shown) so as to sandwich the rib (not shown) 56 and a head portion 52 that connects the pair of sandwiching portions.

  The head portion 52 is formed in a trapezoidal shape in a side view inside the pair of sandwiching portions 56. Moreover, in this clip 50, it is long so that a pair of clamping part 56 can fully bend and deform | transform. The rigidity of the head part 52 is higher than the rigidity of the pair of sandwiching parts 56.

  Further, the pair of sandwiching portions 56 is not formed by a region from the pair of locking portions 64 to the head portion 52, but is downward from a region from the pair of locking portions 64 to the head portion 52. It is formed to hang down.

  Since the clip 50 shown in FIG. 6 is generally formed by a front mold and a back mold with respect to the paper surface of FIG. 6, it has the same shape (cross section) in the direction perpendicular to the paper surface of FIG. )have.

  Such a clip 50 can realize a high removal force by a pair of sandwiching portions 56 having a sufficient thickness, but has a long insertion length so that the pair of sandwiching portions 56 can be sufficiently deformed and deformed. There is an advantage that it is low.

JP-A-10-54411

  However, in the above-described clip 50, in order to keep the insertion force at the time of mounting low, it is necessary to make the pair of sandwiching portions 56 long enough to bend and deform. For this reason, there exists a fault that the whole clip cannot be reduced in size. Further, since the lower ends of the pair of sandwiching portions 56 are in a low position, the degree of freedom of the mounting member mold is small from the viewpoint of slide clearance (see FIG. 4).

  The present invention has been created based on the above findings. The object of the present invention is to provide a clip that can achieve a high extraction force and a low insertion force, but can be made compact in its entirety and can sufficiently increase the degree of freedom of the mold of the mounting member. It is to be.

  The present invention relates to the mounting hole by engaging the edge of the mounting hole and the rib in order to detachably mount the mounting member having the rib protruding to the front side with respect to the mounted member having the mounting hole. A substantially U-shaped clip that is fixed to the front side of the pair of legs, and corresponding to a pair of leg pieces that elastically wrap around the opposite side of the mounting hole. A pair of locking portions adapted to sandwich the edge portion of the corresponding mounting hole in cooperation with the leg piece portion on the side, and to engage with the rib so as to sandwich the rib. The clip is characterized by comprising a pair of sandwiching portions and a head portion connecting the pair of sandwiching portions, wherein the head portion is formed with lower rigidity than the pair of sandwiching portions. .

  According to the present invention, the head portion is formed with a lower rigidity than the pair of sandwiching portions, so that even when the pair of sandwiching portions is formed with a sufficient thickness for realizing a high extraction force, The insertion force can be significantly reduced. And since it is not necessary to form a pair of clamping part long, the whole clip can be made compact and the freedom degree of the metal mold | die of an attachment member can fully be enlarged.

  As a specific aspect in which the head part is formed with lower rigidity than the pair of sandwiching parts, for example, an aspect in which the head part is formed in a shape that bulges outward from the pair of sandwiching parts can be given. For example, the head portion may be formed in a shape that follows an ellipse that is long in the side view. In order to realize further low rigidity, there are a case where the width is narrowed, a case where a hole is formed in the head portion, and the head portion is separated into two hinge portions, for example. Alternatively, as a specific aspect in which the head part is formed with lower rigidity than the pair of sandwiching parts, for example, an aspect in which the head part is formed thinner than the pair of sandwiching parts can be given. For example, the head portion can be formed with a thickness that is half that of the pair of sandwiching portions.

  When the rib has an engagement hole, generally, the pair of holding portions is provided with a pair of engagement claws that engage with the engagement hole formed in the rib.

  In this case, it is preferable that the pair of engaging claws are provided on the opposing surfaces of the pair of sandwiching portions so as not to face each other. When a pair of engaging claws are provided in such a positional relationship, there is an advantage in mold strength when manufacturing by molding using a mold.

  Moreover, it is preferable that the pair of engaging claws are arranged so that the removal force transmitted from the pair of locking portions to the pair of holding portions acts in a direction to close the pair of engaging claws. With such an arrangement relationship, a higher extraction force can be realized.

  According to the present invention, the head portion is formed with a lower rigidity than the pair of sandwiching portions, so that even when the pair of sandwiching portions is formed with a sufficient thickness for realizing a high extraction force, The insertion force can be significantly reduced. And since it is not necessary to form a pair of clamping part long, the whole clip can be made compact and the freedom degree of the metal mold | die of an attachment member can fully be enlarged.

It is a schematic perspective view of the clip in which the head part was made into hinge shape. It is the schematic of the conventional clip.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 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 in a state of being attached to the attachment hole. FIG. 3 is a schematic perspective view of the clip of FIG. 1 attached to the clip tower 20.

  As shown in FIGS. 1 and 2, the clip 10 of the present embodiment is a clip for detachably attaching an attachment member having ribs 35 protruding to the front side with respect to an attachment member having an attachment hole 30. As a whole, it is substantially U-shaped and is fixed to the front side of the mounting hole 30 by engaging with the edges 31 a and 31 b of the mounting hole 30 and the rib 35.

  As a specific configuration, the clip 10 according to the present embodiment corresponds to a pair of leg pieces 11a and 11b that elastically wrap around the opposite sides of the edge portions 31a and 31b of the mounting hole 30. The ribs 35 are sandwiched between the pair of locking portions 12a and 12b adapted to sandwich the edge portions 31a and 31b of the corresponding mounting holes in cooperation with the leg pieces 11a and 11b on the side to be engaged. And a pair of clamping parts 13a, 13b adapted to engage with the ribs 35, and a head part 15 connecting the pair of clamping parts 12a, 12b.

  As shown in FIGS. 1 and 2, the head portion 15 of the present embodiment is formed in a shape that follows an ellipse that is laterally long in a side view. As a result, the head portion 15 is lower than the pair of sandwiching portions 12a and 12b. It is rigid. Further, such a shape also has an advantage that the attachment length can be increased when attaching to the clip tower 20 as shown in FIG.

  The clip 10 of the present embodiment corresponds to the case where the rib 35 has an engagement hole, and is engaged with the engagement hole formed in the rib 35 on the pair of sandwiching portions 13a and 13b. A pair of engaging claws 14a and 14b are provided. In the present embodiment, two protrusions 14p that can contact the rib 35 are provided on each side above the pair of engaging claws 14a and 14b.

  The pair of engaging claws 14a and 14b of the present embodiment are provided on the opposing surfaces of the pair of sandwiching portions 13a and 13b as in the conventional clip, but face each other as in the conventional clip. Instead, they are provided in a positional relationship that does not oppose each other (in an alternate positional relationship). This brings about the advantage that the mold strength can be increased when the clip 10 of the present embodiment is formed by the front mold and the back mold.

  Actually, the clip 10 according to the present embodiment is formed by a front mold and a back mold, and therefore the same shape (in the depth direction) except for the pair of engagement claws 14a and 14b ( Cross section).

  Moreover, in this Embodiment, a pair of clamping part 13a, 13b is formed of the area | region from a pair of latching | locking part 12a, 12b to the head part 15, and a pair of engagement nail | claw 14a, 14b Is arranged on a substantially extension of a region from the pair of locking portions 12a, 12b to the pair of clamping portions 13a, 13b. With such an arrangement relationship, when the clip 10 is inserted, the pair of engaging claws 14a and 14b bends, and when the clip 10 is removed, the removal load is directed from the pair of locking portions 12a and 12b to the pair of holding portions 13a and 13b. As a result, the removal load (extraction force) acts in a direction to close the pair of engaging claws 14a and 14b.

  According to the present embodiment as described above, the pair of sandwiching portions 13a and 13b is sufficient for realizing a high removal force by forming the head portion 15 with a lower rigidity than the pair of sandwiching portions 13a and 13b. Even when it is formed thick, the insertion force at the time of mounting can be remarkably lowered. And since it is not necessary to form a pair of clamping parts 12a and 12b long, the whole clip can be made compact, and as shown in FIG. 4, the freedom degree of the metal mold | die of an attachment member is enough from a viewpoint of a slide clearance. Can be large.

  In addition, the pair of engaging claws 14a and 14b are arranged on a substantially extension of a region extending from the pair of locking portions 12a and 12b to the pair of clamping portions 13a and 13b, thereby a pair of locking portions 12a and 12b. The removal force transmitted to the pair of sandwiching portions 13a and 13b acts in the direction of closing the pair of engagement claws 14a and 14b, so that a higher removal force can be realized.

  In the above embodiment, the head portion 15 is formed in a shape that follows a long ellipse that is laterally long in a side view, but is not limited to such a form at least at the time of filing the present application. Even if the head portion 15 is formed in any other shape that bulges outward from the pair of sandwiching portions 13a and 13b, the head portion 15 is formed to be less rigid than the pair of sandwiching portions 13a and 13b. Is possible. Alternatively, the head portion 15 can be formed with a lower rigidity than the pair of sandwiching portions 13a and 13b by forming the head portion 15 thinner than the pair of sandwiching portions 13a and 13b.

  In order to realize a lower rigidity, a hole may be formed in the head portion 15 as shown in FIG. In the clip 10 shown in FIG. 5, a hollow is formed in the central region of the head portion 15 so as to extend from one clamping portion 13a to the other clamping portion 13b, and the head portion 15 is separated into two hinge portions. Has been. According to such a form, still lower rigidity can be realized.
