A cushion clip that is positioned between the attachment member and the opening / closing lid when the opening / closing lid is closed with respect to the attachment member and elastically supports the opening / closing lid on the attachment member such as a vehicle body. It consists of a cylindrical insertion part to be inserted into the hole and a columnar cushion part that contacts the opening / closing lid. A spiral groove is formed in the circumferential side part of the cushion part, and the cushion part is provided in the insertion part. Is formed on the inner wall of the hole, and a protrusion that fits into the groove is formed in a spiral shape, and the relative length can be displaced in the axial direction by screwing rotation of the cushion part with respect to the insertion part. Is In addition, a plurality of rotational moderation sites are formed at predetermined intervals on the circumferential side of the cushion site to provide a moderation feeling at predetermined rotation intervals along with the threaded rotation of the cushion site to the insertion site, An engagement portion is formed in the insertion portion with respect to the rotational mode imparting portion, and the engagement portion is sequentially engaged with the plurality of rotational mode imparting portions as the cushion portion is screwed and rotated. A feeling of moderation was imparted by engagement of the imparted sites.

In this 1st invention, the rotation mode provision site | part is formed in multiple numbers by the peripheral side part of the cushion site | part. This rotational moderation imparting portion imparts a sense of moderation at a predetermined rotational interval with the fitting rotation (screwing rotation) by the screw action between the cushion portion and the insertion portion.
On the other hand, an engagement part is formed in the insertion part with respect to the rotational mode imparting part. The engaging portion sequentially engages with the rotational mode imparting portion as the cushion portion is screwed.

Next, the cushion clip according to the second invention is the cushion clip according to the first invention, wherein the cushion part is made of an elastomer, and the rotational mode imparting part and the insertion part are resins having higher rigidity than the cushion part. The rotational mode imparting portion is a protruding portion protruding in a convex shape from the inner wall surface constituting the groove portion, and the engaging portion is a protruding piece protruding from the hole edge of the insertion portion into the groove portion.
In the second invention, the cushion portion is made of an elastomer. Further, the rotational mode imparting portion is a protrusion protruding in a convex shape from the inner wall surface constituting the groove. The protrusion is made of a resin having higher rigidity than the cushion part.
On the other hand, the engaging part is a protruding piece protruding from the hole edge of the insertion part into the groove part. The protruding piece is also made of a resin having higher rigidity than the cushion part.
As the cushion portion is screwed and rotated, the plurality of protrusions are sequentially engaged with the protrusion pieces, so that a feeling of moderation is imparted to the cushion clip.

Next, a cushion clip according to a third aspect of the invention is the cushion clip according to the first aspect of the invention, wherein the rotational mode imparting part includes a cushion part peripheral side part sandwiched between two grooves and a cushion part peripheral side part. It consists of a notch cut out radially inward,
The engaging part is a bending piece that abuts on the circumferential part of the cushion part and can be bent and deformed in the screwing rotation direction of the cushion part.
In the third aspect of the invention, the rotational mode imparting portion includes a cushion portion peripheral side portion sandwiched between two groove portions and a notch portion in which the cushion portion peripheral side portion is cut out radially inward.
On the other hand, the engagement part is a bending piece that can be bent and deformed in the screwing rotation direction of the cushion part. The flexure piece is disposed so as to abut on the circumferential side portion of the cushion part.
As the cushion part is screwed and rotated, the cushion part peripheral side part divided by the notch part is sequentially engaged with the flexure piece, thereby giving the cushion clip a sense of moderation.

According to the present invention described above, the following effects can be obtained.
First, according to 1st invention, the support height of a cushion clip is adjusted by screwing and rotating a cushion part with respect to an insertion part. As the cushion clip is screwed and rotated, the engagement portion is sequentially engaged with the rotation mode imparting portion. For this reason, a feeling of moderation is given when the support height of the cushion clip is adjusted. By giving the cushion clip a sense of moderation, the operator can grasp as a feel how much the cushion clip has been screwed and rotated. The cushion clip can be easily attached without requiring visual inspection.

Next, according to the second invention, the protrusion and the protrusion are made of resin having higher rigidity than the cushion part. For this reason, an operator can grasp | ascertain the feeling when both are engaged more clearly.
Next, according to the third invention, since the cushion portion does not have a portion protruding from its original shape, an increase in load during screwing rotation can be suppressed.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 and 2 show a cushion clip according to the first embodiment. FIG. 3 shows a cushion clip according to the second embodiment.
The cushion clips 1 and 2 according to each embodiment are support members attached to a frame body 7 (hereinafter referred to as a frame body 7) that constitutes an engine room. The cushion clips 1 and 2 attached to the frame body 7 elastically support an engine hood (not shown) in a closed state.
The frame body 7 is provided with a mounting hole 5 shown in FIGS. The mounting hole 5 is formed with recesses 9 and 9 that are cut out in a substantially square shape in the radial direction. The cushion clips 1 and 2 are attached to the frame body 7 using the attachment holes 5.

1 is a schematic perspective view of a cushion clip, and FIG. 2 is a sectional view taken along line II-II in FIG.
The cushion clip 1 according to the first embodiment includes an insertion part 10 and a cushion part 20.
First, the cushion part 20 of FIG. 1 is a cylindrical member made of elastomer. The abutting surface 25 of the cushion portion 20 is substantially flush with the engine hood.
A groove portion 22 is formed in a spiral shape on the circumferential side portion of the cushion portion 20. As shown in FIG. 2, a plurality of protrusions 23 are formed in the groove 22 at intervals of 180 degrees. When the protrusions 23 are arranged at intervals of 180 degrees, each time the cushion portion 20 moves by a predetermined interval (0.5 mm to 1.0 mm) as viewed in the vertical direction in FIG. The part 23 comes into contact.

The protrusion 23 is a columnar member having a triangular cross section as shown in FIG. As shown in FIG. 2, the protrusion 23 is disposed in the groove 22 so as not to protrude from the circumferential side of the cushion part 20.
The protrusion 23 is coupled to the upper surface of the groove 22, and a gap is formed between the lower surface of the groove 22 and the protrusion 23. The dimension of this gap is formed smaller than the height dimension of the projection piece 13 described later. For this reason, the protrusion 23 and the protrusion piece 13 always come into contact with the rotation of the cushion part 20 by screwing.
Further, as shown in FIG. 1, the two surfaces (inclined surfaces) facing the circumferential direction of the cushion portion 20 of the protrusion 23 are inclined so that the surfaces approach each other from the upper surface of the groove portion 22 toward the lower surface. ing. The top formed by the two inclined surfaces is chamfered to be rounded.
The protrusion 23 is formed of a resin having higher rigidity than the cushion portion 20 described above.

The insertion site 10 in FIG. 1 is an integrally molded product made of a resin including the storage portion 11, the locking claw 17, and the flange portion 30. This resin has higher rigidity than the elastomer used for the cushion part 20 described above.
The storage part 11 is a cylindrical member having an opening formed at one end thereof. The inner wall of the storage portion 11 is provided with unevenness that can be screwed into the groove portion 22 described above.
The locking claw 17 is a single piece that is folded back from the other end of the storage portion 11 toward the opening at one end. The pair of locking claws 17 and 17 are formed so as to be able to bend and deform in directions approaching each other due to the elasticity of the resin.
The flange portion 30 is a front circular member having an area larger than the opening area of the mounting hole 5. The flange portion 30 is formed in the insertion portion 10 so as to protrude greatly from the periphery of one end of the insertion portion 10 outward in the radial direction of the storage portion 11. A protruding piece 13 is formed on the edge of the flange portion 30.

As shown in FIG. 1, the protruding piece 13 is formed at the edge of the opening of the storage portion 11. One protruding piece 13 is disposed at a portion facing the groove 22 from the edge of the opening.
The protruding piece 13 is also a columnar member having a triangular cross section as shown in FIG. As shown in the figure, the protruding piece 13 is disposed so as to protrude from the flange portion 30 into the groove portion 22.
Further, as shown in the figure, the two surfaces (inclined surfaces) facing the circumferential direction of the cushion portion 20 of the protruding piece 13 are inclined so that the surfaces approach each other from the lower side to the upper side in the same figure. . The top formed by the two inclined surfaces is chamfered to be rounded.
Further, the inclination angle of the inclined surface of the protrusion 13 is the same as the inclination angle of the inclined surface of the protrusion 23 described above. For this reason, when the projection part 23 and the projection piece 13 contact, both inclined surfaces will surface-contact.
The protruding piece 13 is also formed of a resin having higher rigidity than the cushion portion 20.

Next, the attaching operation of the cushion clip 1 will be described with reference to FIG.
First, the cushion clip 1 is inserted into the attachment hole 5 from the insertion site 10 side. At this time, the circumferential direction of the cushion clip 1 is determined so that the locking claw 17 is inserted into the recess 9 of the mounting hole 5.
The locking claws 17 and 17 enter the recess 9 while being pushed and bent in a direction approaching each other by inserting the cushion clip 1 into the mounting hole 5. Further, by inserting the insertion portion 10, the locking claw 17 passes through the mounting hole 5, and the locking claw 17 is engaged with the edge of the mounting hole on the back surface of the frame body 7.

Next, a method for adjusting the support height of the cushion clip 1 will be described.
With the cushion clip 1 attached to the attachment hole 5, the cushion part 20 is screwed and rotated in the insertion direction (right rotation direction as viewed in FIG. 1). By this threading insertion rotation, the groove portion 22 of the cushion part 20 also moves while drawing a spiral in the storage portion 11. Along with the movement of the groove part 22, the protrusion 23 formed in the groove part 22 also moves to the storage part 11. Then, when the groove portion 22 reaches the place where the storage portion 11 enters, the protruding portion 23 and the protruding piece 13 come into contact with each other. In both cases, the resin projection 23 and the projection 13 are in surface contact, and for example, a clicking sound is generated.

Further, by performing screw insertion rotation, the protrusion 23 gets over the protrusion 13 and enters the storage part 11. At this time, the protruding portion 23 is guided upward along the inclination of the inclined surface of the protruding piece 13. The projecting portion 23 guided upward is pressed against the upper surface of the groove portion 22. The upper surface of the groove portion 22 is pushed and bent upward by the elasticity of the elastomer. As a result, the projecting portion 23 sinks into the upper surface of the groove portion 22, and the projecting portion 23 gets over the projecting piece 13 by increasing the gap size between the projecting portion 23 and the lower surface of the groove portion 22.
Further, the protrusion 23 in the storage portion 11 is slightly sunk in the upper surface of the groove 22 as described above. In this state, it moves so as to slide on the uneven inner wall of the storage portion 11. For this reason, the load increase when the projection part 23 moves in the accommodating part 11 is restrained comparatively.

  In addition, as for the protrusion part 23 and the protrusion piece 13, both the surfaces which face the circumferential direction of the cushion part 20 are inclined surfaces. For this reason, even when the cushion part 20 is screwed and rotated in the pulling direction (left rotation direction as viewed in FIG. 1), the protruding portion 23 can get over the protruding piece 13.

Next, the operation and effect of the cushion clip 1 will be described.
First, in the cushion clip 1, the support height of the cushion clip 1 is adjusted by screwing and rotating the cushion portion 20 with respect to the insertion portion 10. As the cushion clip 1 is screwed and rotated, the protruding pieces 13 are sequentially engaged with the protruding portions 23. For this reason, a feeling of moderation is given to the adjustment of the support height of the cushion clip 1. By giving the cushion clip 1 a sense of moderation, the operator can grasp how much the cushion clip 1 has been rotated by the touch. The attachment work of the cushion clip 1 is facilitated without requiring visual inspection.
In addition, the protruding portion 23 and the protruding piece 13 are made of a resin having higher rigidity than the cushion portion 20. For this reason, when both engage, a sound sounds and the operator can grasp the feeling more clearly.

Next, the cushion clip 2 according to the second embodiment will be described with reference to FIG.
The cushion clip 2 includes an insertion part 10a and a cushion part 20a. The insertion part 10 a includes the storage part 11, the locking claw 17, and the flange part 30. That is, the cushion clip 2 has the same basic configuration as the cushion clip 1 according to the first embodiment. Therefore, the same code | symbol is attached | subjected about the same structure and the detailed description is abbreviate | omitted.

The cushion clip 2 is different from the cushion clip 1 in that a cutout portion 27 is formed on the circumferential side portion of the cushion portion 20a.
In the cushion clip 2 of FIG. 3, a plurality of notches 27 are formed at intervals of 180 degrees. In the drawing, only two notch portions 27 located on the back side surface of the cushion clip 2 are indicated by dotted lines from the top.
The notch 27 is a recessed portion formed by notching the circumferential side portion of the cushion part 20a inward in the radial direction. The notch 27 has a depth that does not allow at least a tip portion of a flexure piece 40 to be described later to contact.

Further, a bending piece 40 is formed at the insertion site 10a. The bending piece 40 is a substantially L-shaped plate member. One end of the bending piece 40 is connected to the flange 30.
The other end 40a protrudes radially inward of the cushion part 20a. The other end 40a protrudes so as to be in contact with at least the circumferential side portion of the cushion part 20a.
The thickness of the other end 40a decreases as it goes to the tip. For this reason, the tip end portion of the other end portion 40a is easily bent and deformed in the screwing rotation direction of the cushion portion 20a.

According to the above-described cushion clip 2, due to the screwing rotation of the cushion part 20, the bending piece 40 is pressed against the circumferential side part of the cushion part 20 a and is bent in the screwing rotation direction. And in the location where the notch part 27 was formed, the pressing to the bending piece 40 is lose | eliminated and the bending piece 40 returns to the original shape. Further, due to the threaded rotation of the cushion part 20a, the bending piece 40 passes through the notch 27 and is again pressed against the circumferential side part of the cushion part 20a to be bent. When the bent piece 40 is bent and deformed, the cushion portion 20a and the bent piece 40 come into contact with each other to make a sound. The operator can feel a sense of moderation due to this sound and a change in load caused by the bending of the bending piece 40.
Furthermore, according to the cushion clip 2, there is no portion protruding from the original shape of the cushion part 20a. For this reason, the load produced when the cushion part 20a moves in the storage part 11 is the same as before.

  Examples of the “resin” used as the material for both the insertion site 10 of Example 1 and the insertion site 10a of Example 2 include polyacetal (POM), polyvinyl alcohol, polyvinyl chloride, polyvinylidene chloride, polyethylene, polystyrene, and polypropylene. , Polyamide, polyvinyl acetate, acrylonitrile = styrene copolymer (AS), acrylonitrile = butadiene = styrene copolymer (ABS), thermoplastic resin, phenol resin, epoxy resin, unsaturated polyester resin, urea resin, melamine resin There are thermosetting resins such as polyurethane resin and silicone resin. The above resins may be used alone or in combination of two or more. The resin insertion portion is desirable because it is lighter than that of a material such as metal.

  At the same time, “elastomer” used as a material of the cushion part 20 (20a) is a polymer having rubber elasticity at room temperature. For example, styrene elastomer (SBC), olefin elastomer (TPO), vinyl chloride elastomer (TPVC), urethane elastomer (TPU), polyester elastomer (TPEE), polyamide elastomer (TPAE), fluorine elastomer, chlorination There are cross-linked ethylene copolymer alloy (Alcrine) and chlorinated polyethylene (CPE).

[Other embodiments]
The cushion clips 1 and 2 according to the present invention are not limited to the above-described embodiments, and can take other various embodiments.
First, the shape of the protrusion 23 can take various shapes. For example, it may be a columnar member having a semicircular cross section. Moreover, the flat plate member which can be bent and deformed in the screwing rotation direction of the cushion part 20 may be used. Moreover, the hemispherical projection part 23 may be sufficient.
Further, only the left surface of the protrusion 23 as viewed in FIG. 1 may be an inclined surface, and the right surface may be a surface perpendicular to the upper surface of the groove 22. In this case, the protrusion 23 gets over the protrusion 13 at the time of screw insertion rotation. On the other hand, at the time of screwing rotation in the pulling direction (left rotation direction as viewed in FIG. 1), the protruding portion 23 is caught by the protruding piece 13 and the screwing rotation is stopped. As a result, the cushion part 20 can be prevented or reduced from coming off the insertion part 10.
Moreover, the formation position of the projection part 23 can also be changed suitably. That is, the protrusions 23 may be provided in the groove 22 at intervals of 60 degrees, or may be provided at intervals of 360 degrees.
The shape of the protruding piece 13 can be changed as appropriate. Two or more protruding pieces 13 may be formed.

Next, the shape of the notch 27 can be changed as appropriate. Moreover, the formation position and the number of formation of the notch part 27 can be changed suitably. Also in this case, it is desirable to form the notch 27 at a position corresponding to the support height of the cushion part 20.
Moreover, the shape of the bending piece 40 can also be changed suitably. Two or more flexure pieces 40 may be formed.

  Next, the support height of the cushion clip 1 may be adjusted before the cushion clip 1 is attached to the attachment hole 5.

  Next, the cushion part 20 and the protrusion 23 may be formed of the same material. For example, the above-mentioned moderation feeling can be obtained by integrally forming the cushion portion 20 and the protrusion 23 with an elastomer having a hardness of about 90.

Next, the attachment hole 5 may be formed on the engine hood side. In this case, the cushion clip 1 (2) is attached to the engine hood side.
Further, the attachment holes 5 may be formed in both the engine hood and the frame body 7. If it does in this way, the freedom degree of the attachment location of cushion clip 1 (2) will spread. For example, the cushion clip 1 (2) can be alternately attached to both the engine hood and the frame body 7.

  Next, the cushion clip 1 (2) can be applied to each part of the vehicle that can be opened and closed, such as a door and a trunk, in addition to the engine room.
