DETAILED DESCRIPTION OF THE INVENTION
<First Embodiment>
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a first embodiment of the invention will be described with reference to the drawings. This embodiment demonstrates the case where this invention is applied to the clip for attaching the assist grip A (fixed object) of a motor vehicle. As shown in FIG. 10, the assist grip A is attached to a position near the side glass G on the roof surface of the rear part of the automobile. However, a molded ceiling is used for this roof surface.
[0013]
The assist grip A is formed in a substantially U shape by a synthetic resin material, and a clip for attachment (clip body 1) is embedded at both ends by insert molding. However, the window 2 is opened at the end surface of the assist grip A, the upper surface of the clip body 1 is exposed at the bottom surface, and a cover body 3 to be described later can be inserted therefrom.
[0014]
As shown in FIG. 2, the clip includes a clip body 1 formed of a synthetic resin material and a cover body 3 (regulating member) inserted into the clip body 1. First, the clip main body 1 will be described. The upper portion of the clip main body 1 is a base portion 4 embedded in the assist grip A. The base 4 includes a substrate 5 formed in a square shape, and an upper plate 6 and a lower plate 7 that sandwich the substrate 5 from above and below and are formed smaller than the substrate 5. The reason why the upper and lower plates 6 and 7 are stepped all around the substrate 5 is to prevent the assist grip A from coming off mechanically.
[0015]
Further, a cover housing hole 8 passes through the base 4 from the upper plate 6 to the lower plate 7 in the vertical direction. The cover receiving hole 8 is formed so that the cover main body 3 can be inserted. In this embodiment, the cover receiving hole 8 is formed in a substantially square shape. However, one side of the back side shown in FIG. It is a guide groove 9 for guiding. Further, in the cover housing hole 8, a pair of elastic locking pieces 10 are formed on the wall surface on which the guide groove 9 is formed and the wall surface facing the wall, as shown in FIGS. 3 is held in a temporarily fixed position (position shown in FIGS. 5 and 6) and a final fixed position (position shown in FIG. 8). Both elastic locking pieces 10 are formed in a vertical direction starting from the opening edge of the cover housing hole 8 and are allowed to bend in the expanding direction. Furthermore, the latching claw 11 is formed in the front-end | tip so that it may mutually face.
[0016]
Further, a projecting piece 12 protrudes horizontally from one side edge on the outer surface of the substrate 5, and an insertion pin 13 is suspended from the lower surface of the tip portion. The insertion pin 13 is inserted into a pin hole 15 penetrating the roof panel 14 so that the assist grip A strengthens the temporarily fixed state of the roof panel 14. Further, the insertion pin 13 has a conical shape at the tip, but the shaft portion is chamfered 13A from two directions along the axial direction (see FIG. 11), and the locking rod 16 is formed on the other peripheral surface. A plurality of layers protrudes along the height direction, and is selectively hooked to the edge of the pin hole 15. The base portion of the overhanging piece 12 and the insertion pin 13 is embedded in the assist grip A together with the base portion 4.
However, the pin hole 15 is formed in a long hole shape as shown in FIG. This is to allow the insertion pin 13 to move in the pin hole 15 when the clip body 1 moves in the mounting hole 17 as the cover is inserted, as will be described later.
[0017]
Legs 18 for attachment to the roof panel 14 are integrally suspended from the lower surface of the lower plate 7 in the base 4. In this embodiment, the leg portion 18 is formed by a pair of leg pieces 19 facing each other with the cover housing hole 8 interposed therebetween. Both leg pieces 19 are formed so that the connecting portion with the lower plate 7 is a little thin, and can be satisfactorily deformed when the roof panel 14 is inserted into the mounting hole 17. The attachment hole 17 is a square hole.
In addition, the outer surface of the portion that continues to the base portion of both leg pieces 19 is thick in an inclined shape, and serves as a locking portion 20 that elastically locks to the edge of the mounting hole 17. Furthermore, the tip portions of both leg pieces 19 are gradually thinned, and chamfered so that both side edges in the width direction are tapered, thereby making it easy to insert both leg pieces 19 into the mounting holes 17. Yes. Further, a hooking portion 21 is formed in a step shape on a portion adjacent to the locking portion 20 on one side edge (the side edge on the near side in FIG. 2) of both leg pieces 19, and the opening of the mounting hole 17. The edge can be locked to a side different from the both locking portions 20. However, in the initial insertion state of the leg pieces 19 with respect to the mounting holes 17, the both hook portions 21 are separated from the opening edges of the mounting holes 17, and when the clip body 1 moves in the mounting holes 17 as will be described later. In addition, both hooks 21 are locked.
[0018]
In addition, a pair of spacer pieces 22 formed slightly narrower than the lower plate 7 are suspended from the lower plate 7 at positions outside the both leg pieces 19. Both spacer pieces 22 are used to hold the lower plate 7 so as to be lifted from the roof panel 14 by the thickness of the roof head lining 23 of the molded ceiling, and are both abutted against the roof panel 14. Yes.
[0019]
Next, the cover body 3 will be described. The cover body 3 is formed in a prismatic shape that can be inserted into the window portion 2 and the cover accommodation hole 8. Further, a biting protrusion 24 is provided on the upper surface of the cover main body 3, and when a cover 25 made of a different material as shown in FIG. It is for ensuring the mechanical connection strength of the. Further, a guide edge 26 projects outwardly on one surface of the cover main body 3 over almost the entire length, and can be fitted along the guide groove 9. Further, a cover plate 27 is formed so that the upper surface of the cover main body 3 also projects outward, so that the cover receiving hole 8 can be covered by contacting the upper plate 6 of the clip main body 1. On the other hand, the front end portion of the cover body 3 is chamfered from four sides and has a tapered shape to facilitate insertion into the cover housing hole 8. Among these, when the cover main body 3 is accommodated in the cover accommodating hole 8, the surface located on the opposite side of the clip body 1 from the hook portion 21 is a guide surface 28, and the cover main body 3 is inserted. The entire clip can be moved within the mounting hole 17 so as to be in sliding contact with the opening edge of the mounting hole 17, thereby locking the hook portion 21 to the opening edge of the mounting hole 17.
[0020]
Also, on both the outer surface of the cover body 3 on which the guide edge 26 is formed and the surface opposite to the surface, locking recesses 29A and 29B are formed on the upper and lower sides, respectively. Each of the ten locking claws 11 is detachably engaged. Of these, the lower locking recess 29B is for holding the cover body 3 in a shallow position, that is, a temporarily fixed position, when the cover body 3 is inserted into the cover receiving hole 8, and the upper engagement recess 29B. The stop recess 29A is for holding the cover body 3 at a deep position, that is, at the final stop position.
[0021]
Next, the effect of this embodiment comprised as mentioned above is demonstrated concretely. First, the cover 25 in which the cover body 3 is inserted is inserted into the cover accommodation hole 8 through the window portion 2 with respect to the assist grip A in which the clip body 1 is embedded at both ends. At this time, since the guide edge 26 is inserted along the guide groove 9, a stable insertion state can be obtained. When the lower locking recess 29B is inserted to a depth that matches the locking claw 11 of the elastic locking piece 10, the locking claw 11 is elastically engaged with the corresponding locking recess 29B, As a result, the cover 25 is held at the temporary fixing position with respect to the clip body 1.
[0022]
In this way, both ends of the assist grip A integrated with the cover 25 are applied to the mounting portion of the molded ceiling. That is, at the mounting site, holes are formed in the roof head lining 23 of the molded ceiling so as to align with the mounting holes 17 and the pin holes 15 respectively, and both the leg pieces 19 and the insertion pins 13 are inserted through these holes. Insertion is performed. At this time, both leg pieces 19 are inserted into the mounting hole 17 while being constricted and deformed, and when the spacer pieces 22 are inserted until they contact the roof panel 14, the leg pieces 19 are elastically restored and the locking portions 20 are restored. Is locked to the opening edge of the mounting hole 17. On the other hand, the insertion pin 13 is inserted into the central portion of the pin hole 15 with any one of the locking rods 16 hooked to the opening edge of the pin hole 15. Accordingly, in the assist grip A, the both locking portions 20 are elastically engaged with the opening edge of the mounting hole 17, and the flange edge of the insertion pin 13 is locked with the opening edge of the pin hole 15. On the other hand, although it is temporarily fixed, it is held with a sufficient engaging force to be held by the roof panel 14 even if the operator does not support it by hand.
[0023]
From this state, a pressing force is applied to the cover 25 to disengage both locking claws 11 from the lower locking recess 29B. When the cover 25 is pushed deeper as it is, the guide surface 28 of the cover 25 comes into sliding contact with the opening edge of the mounting hole 17, so that the clip body 1 moves in a direction perpendicular to the pushing direction, that is, in the right direction in FIG. . When the cover 25 is inserted to a depth at which the locking claw 11 is locked to the upper locking recess 29A, and the clip body 1 is held at the final locking position, the hook portions 21 of both leg pieces 19 are moved. Each of the mounting holes 17 is held in an engaged state with the opening edge. Since the engaging direction of the hook portion 21 with respect to the opening edge of the mounting hole 17 is a direction perpendicular to the bending direction of the leg piece 19, the leg piece 19 is immediately constricted even if a force in the pulling direction acts on the assist grip A. The engagement with the roof panel 14 is not dissociated due to deformation. Further, since the cover 25 is split between the leg pieces 19 by the above-described pushing, the squeeze deformation that releases the locking of the locking portions 20 in the both leg pieces 19 is restricted. In addition, since the clip body 1 is locked to the three sides of the mounting hole 17 by the both hook portions 21 and the both locking portions 20, it is also effective for external force acting from a plurality of directions. Reliability can be increased.
[0024]
As described above, according to this embodiment, both leg pieces 19 are inelastically locked in a direction orthogonal to the locking release direction. Therefore, although it can be inserted into the roof panel 14 relatively easily and smoothly, it is firmly locked after the mounting, so that it is particularly suitable for mounting parts such as the assist grip A in which a force acts in the pulling direction. It is advantageous. Moreover, since it latches with respect to the attachment hole 17 from three directions together with the latching | locking part 20 of the leg piece 19, stable support is obtained with respect to multiple directions. Further, since the clip body 1 is automatically moved by using the pushing operation of the cover 25, the workability is excellent. Further, in a state where the assist grip A before the cover 25 is pushed into the full locking position is temporarily fixed, the elastic locking force by the leg piece 19 is enhanced by the insertion pin 13, so that the operator can assist the assist grip A. It is not necessary to hold the handle, and the work becomes easier.
[0025]
Second Embodiment
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. In this embodiment, the present invention is applied to a clip C for attaching a sun visor S (fixed object) of an automobile, and a locking shaft 34 is provided on the clip body 1 so as to be in parallel with the legs 18. This is different from the first embodiment.
As shown in FIG. 16, a pair of left and right sun visors S are attached to positions near the windshield F on the roof surface.
[0026]
The sun visor S has a configuration in which a rotating shaft 30 made of a metal bar is drawn from an end portion of a light shielding plate B made of synthetic resin and having a substantially rectangular shape. The light shielding plate B is attached to the rotation shaft 30 so as to be rotatable. A clip C is attached to the tip of the rotation shaft 30, and the entire sun visor S is attached to the roof surface so as to be rotatable by the clip C. As a result, the sun visor S enables the light shielding plate B to rotate in the vertical direction and the horizontal direction about the clip C.
In the present embodiment, the clip C is configured such that the cover body 3 formed integrally with the cover 25 can be inserted into the clip body 1.
[0027]
As shown in FIG. 13, the base 4 of the clip body 1 is formed in an elliptical shape by a synthetic resin material, and the upper surface is curved from the center toward the outer periphery. A bearing portion 32 that protrudes to the lower surface side is formed at the center of the base portion 4, and the leg portion 18 and the locking shaft 34 are integrally formed on the lower surface of the base portion 4 at a symmetrical position about the bearing portion 32. Yes.
[0028]
The bearing portion 32 penetrates the insertion hole 32B along the axial center, and a total of four slits are provided at the lower end portion every 90 ° and along the axial direction from the end surface, thereby slightly expanding. The four elastic receiving pieces 33 are allowed. When the bearing portion 32 receives the rotation shaft 30 from the insertion hole 32 </ b> B, the bearing portion 32 expands the elastic receiving piece 33 and inserts the rotation shaft 30. The rotation shaft 30 is constricted at the tip thereof to form a retaining recess 31, and the elastic receiving piece 33 engages with the retaining recess 31, so that the bearing portion 32 rotatably mounts the rotation shaft 30. The bearing portion 32 is attached by inserting the cylindrical portion 32A into the shaft hole 36 of the roof panel. The shaft hole 36 is formed in a long hole shape (see FIG. 17). As will be described later, when the leg piece 19 moves in the mounting hole 17, the bearing portion 32 also moves in the shaft hole 36. This is to allow that. Moreover, in this embodiment, the spacer piece 22 is provided in the radial shape centering on the bearing part 32 among the lower surfaces of the base part 4 (refer FIG. 13).
[0029]
The leg portion 18 has the same configuration as that of the first embodiment, and the hook portion 21 of both leg pieces 19 is provided at a position opposite to the bearing portion 32.
[0030]
Now, the locking shaft 34 is disposed on the lower surface of the base portion 4 on the opposite side of the leg portion 18 with the bearing portion 32 interposed therebetween, and has a cylindrical shape (see FIG. 13). Further, a tapered surface 34A is formed at the lower end of the locking shaft 34 over the entire circumference, facilitating insertion into the locking hole 37. The locking hole 37 is a circular hole (see FIG. 17).
As shown in FIG. 13, a hooking recess 35 (auxiliary hooking portion) is formed at the base portion of the locking shaft 34 and on the side facing the bearing portion 32. The end surface 35A of the hooking recess 35 is formed in a circumferential surface that protrudes in the direction of the bearing portion 32 in accordance with the opening edge of the locking hole 37, and comes into contact with the side surface of the opening edge of the locking hole 37 without a gap. .
[0031]
Next, the effect of this embodiment comprised as mentioned above is demonstrated.
Similar to the first embodiment, the latching claw 11 of the elastic latching piece 10 is engaged with the lower latching recess 29B, so that the clip body 1 with the cover 25 temporarily secured is applied to the mounting portion of the molded ceiling. . The roof panel 14 of this mounting part has a mounting hole 17, a shaft hole 36 and a locking hole 37 (see FIG. 17), and when both leg pieces 19 are inserted into the mounting hole 17 while being deformed, Accordingly, the bearing portion 32 is inserted into the shaft hole 36, and the locking shaft 34 is inserted into the locking hole 37, respectively. Then, as shown in FIG. 14, when the insertion is made until the spacer piece 22 comes into contact with the roof panel 14, the leg piece 19 is elastically restored and the locking portion 20 is locked to the opening edge of the mounting hole 17.
[0032]
When the cover 25 is pushed in from this state, the lower locking recess 29B is released, and the clip body 1 is moved in the pushing direction by sliding contact between the guide surface 28 of the cover 25 and the opening edge of the mounting hole 17. Moves in the orthogonal direction, that is, in the right direction in FIG. Then, the locking shaft 34 and the bearing portion 32 formed integrally with the clip body 1 move in the right direction in the drawing as the clip body 1 moves. Here, as shown in FIGS. 15 and 17, the hook portion 21 of the leg piece 19 is locked to the opening edge of the mounting hole 17, and at the same time, the hook recess 35 of the lock shaft 34 is locked. It is locked to the opening edge of the hole 37. At this time, the hooking recess 35 is fitted with a gap between the end face 35 </ b> A having a circumferential surface shape contacting the side surface of the opening edge of the locking hole 37. Thereby, since the force in the pulling direction can be received by the entire lower surface of the hooking recess 35, a sufficient locking force can be obtained.
[0033]
When the locking claw 11 is locked in the upper locking recess 29A and the pushing of the cover 25 is completed, the deformation of the leg piece 19 is restricted and the movement of the clip body 1 is restricted. The portion 21 and the hook recess 35 are held in a locked state. Here, since the hooking portion 21 and the hooking recess 35 are locked in a direction orthogonal to the insertion direction of the leg piece 19 and the locking shaft 34, the clip body 1 is prevented from being pulled out.
Further, since the leg piece 19 and the locking shaft 34 are formed at substantially point-symmetrical positions with respect to the bearing portion 32 of the clip body 1, the force acting on the bearing portion 32 from the light shielding plate B via the rotating shaft 30. Is evenly supported.
[0034]
As described above, according to the present embodiment, the leg piece 19 and the locking shaft 34 are locked in the direction orthogonal to the insertion direction by the locking of the hook portion 21 and the hook recess 35. Therefore, although the attachment to the roof panel 14 can be performed relatively easily and smoothly, after the attachment, in addition to the engagement of the leg piece 19, the clip C is firmly locked because the locking shaft 34 is used for locking. The Furthermore, the base 4 can be stably supported by the leg piece 19 and the locking shaft 34 supporting the force acting on the bearing portion 32 evenly. In particular, since the light shielding plate B of the sun visor S is used by being rotated in various directions, the attachment of components such as a clip C for fixing the sun visor S, in which the direction in which the force acts changes depending on the use situation. Is advantageous. In addition, since the locking between the leg piece 19 and the locking shaft 34 is simultaneously performed by the movement of the clip body 1 by the pushing operation of the cover 25, the workability is excellent.
[0035]
