DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for fixing, for example, an assist grip, a sun visor or a rod holder of an automobile.

[0002]

2. Description of the Related Art Heretofore, there has been a clip of this type in which the above-mentioned equipment is fixed using a mounting hole opened in a mounting surface of a body or the like. Some of such clips include a pair of temporary locking pieces that are locked to the mounting holes. The two temporary locking pieces are provided with elasticity such that they squeeze and deform when passing through the mounting hole, and the protrusion formed on the base side returns when the mounting hole passes through the mounting hole to return to the hole of the mounting hole. They are hooked on the rim and locked.

[0003]

However, with such an elastically retaining structure, the retaining force against the detachment is not always sufficient. In particular, in the case where a strong pulling force acts such as an assist grip, a structure for increasing the locking force is required. The present invention has been developed to meet such a demand, and an object of the present invention is to provide a clip that can increase the reliability of attachment of equipment.

[0004]

According to a first aspect of the present invention, there is provided a base for connecting to an object to be fixed.
A locking portion integrally provided from the base portion and inserted into a mounting hole drilled in the mounting surface and locked to the edge of the hole, thereby enabling the object to be fixed to the mounting surface. A clip made of a resin having a clip body, wherein the locking portion bends and deforms into the mounting hole and can be temporarily locked to a hole edge of the mounting hole; Has a hook portion protruding in a direction different from the bending direction of the hook, and this hook portion is loosely inserted into the mounting hole when the temporary locking portion is inserted into the mounting hole, and thereafter the entire locking portion is And a non-deflectable main locking portion that locks the entire clip with the hole edge of the mounting hole so as to prevent the entire clip from slipping off when the hook is moved. It is. According to a second aspect of the present invention, in the first aspect, a guide member having a guide surface at a distal end portion is provided, and the guide member can be inserted into a receiving hole provided in the clip body. When the guide surface slides on the mounting hole with the insertion, the entire clip can be guided in a direction in which the hook portion is locked to the opening edge of the mounting hole. According to a third aspect of the present invention, in the second aspect, the temporary locking portion is constituted by at least a pair of deflectable temporary locking pieces while the guide member is inserted into the accommodation hole. The guide member is capable of restricting bending deformation of the temporary locking piece by breaking into between the temporary locking pieces. According to a fourth aspect of the present invention, in the third aspect, the guide member includes a primary locking position in which the temporary locking pieces are allowed to bend and deform with respect to the clip body, and the temporary locking positions. It is characterized in that it can be locked at a secondary locking position that restricts the bending deformation of each temporary locking piece by breaking between the pieces.

[0005]

According to the first aspect of the present invention, the locking portion is inserted into the mounting hole of the mounting surface in a state where the base and the object are connected. At this time, first, the temporary locking portion is inserted into the mounting hole while being bent and deformed, and is elastically locked to the hole edge of the mounting hole. As a result, the object is temporarily fixed to the mounting surface. Next, if the entire clip body is moved in a direction orthogonal to the bending direction of the temporary locking portion,
The hook portion is engaged with the edge of the mounting hole. by this,
As a result, the object to be fixed is fixed to the mounting surface. In this fixed state, even when a force is applied to the fixed object in the direction of pulling out from the mounting hole, the hooking portion is arranged in a direction different from the bending direction of the temporary locking portion, that is, the disengaging direction. , Is less likely to come off. In addition, since the main locking portion having the hook portion is locked so as not to bend, it does not dissociate and deform even when a strong force in the pull-out direction acts, so that a high holding force can be obtained. According to the second aspect of the present invention, when the guide member is inserted into the accommodation hole in a state where the temporary locking portion is temporarily locked to the hole edge of the mounting hole, the guide surface of the guide member is attached to the mounting hole in the insertion process. Therefore, the clip body moves in the mounting hole in response to the guiding operation of the guide surface, and the hook portion of the locking portion can be locked in the mounting hole. Therefore, according to the second aspect of the present invention, the entire clip can be automatically moved to a position where the hook portion is locked by simply inserting the guide member, thereby enhancing workability. According to the third aspect of the present invention, when the guide member is inserted into the accommodation hole, the guide member is split between the respective temporary locking pieces. Thereby, since the guide member regulates the disengagement deformation of the temporary locking piece, the locking state is strengthened. According to the invention of claim 4, the guide member is integrated with the clip main body at the primary locking position before reaching the secondary locking position for restricting the bending of each temporary locking piece. Since the guide member is allowed to bend and deform at the primary locking position, the clip body can be inserted into the mounting hole with the guide member attached. Therefore, the clip main body can be carried into the mounting work site of the fixed object with the guide member integrated.

[0006]

<Embodiment 1> Hereinafter, Embodiment 1 will be described.
Will be described with reference to the drawings. In this embodiment, a case where the present invention is applied to a clip for attaching an assist grip A (an object to be fixed) of an automobile will be described. As shown in FIG. 16, the assist grip A is attached to a position near the side glass G on the rear roof surface of the interior of the vehicle. However, a molded ceiling is used for the roof surface.

The assist grip A is formed in a substantially U-shape by a synthetic resin material. At both ends thereof, a clip (clip main body) for attachment described below is exposed to the lower surface side by insert molding so that the engaging portion is exposed. It is embedded in the state. However, a window W is opened on the end surface of the assist grip A, and the upper surface of the clip body is exposed on the bottom surface thereof, and the guide member 3 described later can be inserted therefrom.

[0008] The clip 1 of this embodiment comprises a clip body 2 formed of a synthetic resin material, and a guide member 3 inserted therein. First, from the clip body 2, the upper portion of the clip body 2 is a base 4 embedded in the assist grip A. The base 4 includes a rectangular substrate 5 and an upper frame 6 and a lower frame 7 which sandwich the substrate 5 from above and below and are formed smaller than the substrate 5. Thus, the upper and lower frames 6, 7
The reason why the step is formed on the entire circumference with the substrate 5 interposed therebetween is to mechanically prevent the assist grip A from coming off.

An accommodation hole 8 through which the guide member 3 can be inserted is vertically penetrated through the substrate 5. In this embodiment, the accommodation hole 8 is formed in a flat T-shape, and one side thereof serves as a guide groove 9 for positioning the guide member 3 in the insertion direction. A pair of elastic locking pieces 10 are formed on the opening edge of the receiving hole 8 on the side orthogonal to the guide groove 9, and serve to hold the guide member 3 at the primary locking position and the secondary locking position. Fulfill. That is, the two elastic locking pieces 10
Are allowed to bend in the expanding direction, and locking claws 11 are formed at their ends so as to face each other.

Further, a roof panel 12 is provided on the lower surface of the base 4.
An engaging portion 14 for attachment to the (mounting surface) is integrally hung. The entire locking portion 14 is formed so as to be insertable into a mounting hole 13 formed in the roof panel 12, and includes a flexible temporary locking portion 15 and a non-flexible permanent locking portion 16. The temporary locking portion 15 has a pair of temporary locking pieces 15 </ b> A which are formed to be flexible and continuous below the elastic locking pieces 10 at the opening edge of the accommodation hole 8 so as to be continuous therewith. Both the temporary locking pieces 15A can be inserted while being narrowed and deformed in the mounting hole 13. A temporary locking step 15B is formed at a position near the base of the two temporary locking pieces 15A in a stepped shape.
It can be elastically engaged with the edge of the mounting hole 13.

[0011] Further, at the edge of the opening edge of the accommodation hole 8 on the side facing the guide groove 9, a main hook constituting the main hooking portion 16 is provided separately from the two temporary hooking pieces 15 A. Stop 16A
Are formed so as not to bend. The length of the final locking piece 16A is set to be substantially the same as the length of the two temporary locking pieces 15A, but the width is set to the two temporary locking pieces 15A.
Are formed narrower than the dimension between the outer surfaces of the temporary locking step 15B, which is the widest part, and when the entire locking portion 14 is inserted into the mounting hole 13, both the temporary locking pieces 15A are bent and deformed. While the insertion is allowed, the insertion is allowed while the final locking piece 16A is kept as it is.

Also, in the final locking piece 16A, the final locking step 16B (hook portion) is located at substantially the same height as the provisional locking step 15B is provided on the temporary locking piece 15A. It is formed in a step shape. The final locking step 16B can be locked in a state in which the temporary locking step 15B cannot bend to an edge orthogonal to the edge that is temporarily locked to the opening edge of the mounting hole 13. However, at the initial stage when the locking portion 14 is inserted into the mounting hole 13, both the temporary locking pieces 15 </ b> A are locked at the edge of the mounting hole 13, but the final locking piece 16 </ b> A is When the clip body 2 moves within the mounting hole 13 as described later, the final locking piece 16A can be locked.

Further, the two temporary locking pieces 1 are provided on the lower surface of the lower frame 7.
A pair of spacer pieces 17 hang down on both sides on the same side as where the 5A is arranged. Both spacer pieces 17 have a length substantially equivalent to the thickness of the roof lining 18 (having elasticity) of the molded ceiling, and when the clip 1 is mounted, the spacer piece 17 is abutted against the roof panel 12 to float the substrate 5. It can be held in a state where it is held.

Next, the guide member 3 will be described. The guide member 3 is formed so as to be inserted into the window W and the accommodation hole 8. On the upper surface of the guide member 3, a half-circle ring-shaped biting projection 19 is provided in a protruding manner. This is the guide member 3
Is used to create a cover C that compensates for the window W as shown in FIG.
The purpose of this is to ensure mechanical connection strength by sneaking in a different kind of material (the same kind of resin material) during insert molding of the cover body C.

On one surface of the guide member 3, a guide piece 20 projects in the left-right direction over substantially the entire length, and can be fitted along the guide groove 9. Further, the upper surface of the guide member 3 also protrudes in the horizontal direction, so that the housing hole 8 can be covered. A guide surface 21 having an inclined surface that tapers the tip of the guide member 3 is formed on the surface of the guide member 3 on the side where the guide piece 20 is provided. The guide surface 21 is in sliding contact with the opening edge of the mounting hole 13 when the guide member 3 is inserted into the housing hole 8, so that the final locking step 16 </ b> B is locked to the opening edge of the mounting hole 13. ,
The entire clip 1 can be moved within the mounting hole 13. However, in this embodiment, three ridges 22 shown in the figure protrude vertically on the outer surface of the guide piece 20,
The resistance at the time of sliding contact with the hole edge of the accommodation hole 8 and the hole edge of the mounting hole 13 can be reduced.

In addition, locking recesses are provided on the side surface of the guide member 3 so as to be releasably locked with the locking claws 11 of the elastic locking pieces 10 respectively. Of these, the lower locking recess 2
Reference numeral 3 denotes a height position (primary locking position) at which the two temporary locking pieces 15A are allowed to bend when the guiding member 3 is inserted into the accommodation hole 8.
The upper locking concave portion 24 is split between the two temporary locking pieces 15A, and is held at a height position (secondary locking position) that restricts bending thereof. be able to.

Next, the operation and effect of this embodiment configured as described above will be specifically described. First, the clip body 2
Is inserted into the receiving hole 8 through the window W with respect to the assist grip A embedded at both ends. When the lower locking recess 23 is inserted to a depth that is compatible with the locking claw 11 of the elastic locking piece 10, the locking claw 11 is elastically locked in the lower locking recess 23. Thereby, the guide member 3 (the cover body C) is held at the primary locking position with respect to the clip body 2.

In this manner, both ends of the assist grip A with the cover C integrated therewith are applied to the mounting portions of the molded ceiling. That is, holes are provided at the mounting portion in the roof lining 18 of the molded ceiling in alignment with the mounting holes 13, and the two temporary locking pieces 1 are passed through these holes.
A 5A plug-in is made. During this time, the permanent locking pieces 16A are inserted as they are, but the two temporary locking pieces 15A are inserted into the mounting holes 13 while being narrowed and deformed. And
When the spacer piece 17 is inserted until the spacer piece 17 comes into contact with the roof panel 12, the final locking step 1 of the final locking piece 16A is performed.
Although 6B is separated from the opening edge of the mounting hole 13,
The two temporary locking pieces 15A elastically return, and the temporary locking step 15B is elastically locked to the opening edge of the mounting hole 13. Thus, the assist grip A is temporarily fixed to the roof panel 12, but is held with a sufficient engaging force to be held by the roof panel 12 without being supported by a worker.

From this state, a pushing force is further applied to the cover body C to disengage both the locking claws 11 from the lower locking recess 23. If the cover body C is pushed further deep as it is, the two locking claws 11 are locked in the upper locking recess 24, so that the guide member 3 (cover body) is held at the secondary locking position with respect to the clip body 2. Is done. The guide surface 21 of the guide member 3 comes into sliding contact with the opening edge of the mounting hole 13 from the above-described primary locking position to the secondary locking position. Along with this, the clip body 2 moves in a direction orthogonal to the pushing direction, that is, in the right direction in FIG. As a result, the final locking step 16B of the final locking piece 16A is locked to the opening edge of the corresponding mounting hole 13 in a state where it cannot bend. At the same time, the guide member 3
Is inserted between the two temporary locking pieces 15A, and the temporary locking pieces 15A
, That is, the deformation in the direction of disengaging from the opening edge of the mounting hole 13.

Therefore, it can be said that the clip 1 is sufficiently prevented from coming off only by the two temporary locking pieces 15A. However, since the temporary locking piece 15A is required to have a temporary locking function, the temporary locking piece 15A itself has a rigidity with which good elasticity is exhibited. Cannot be set. Therefore, even in the secondary locking state, the engagement force may not always be sufficient with only the temporary locking pieces 15A depending on the rigidity of the temporary locking pieces 15A when a strong pulling force is applied. obtain. But,
In this embodiment, since the permanent locking piece 16A, which cannot be bent, that is, has sufficient rigidity, is arranged separately from the temporary locking piece 15A, the problem of insufficient engaging force is solved. Therefore, as in the case of the assist grip A, when the clip 1 is applied with a strong force in the pull-out direction, reliable holding is achieved.

<Embodiment 2> FIGS. 10 to 15 show Embodiment 2 of the present invention. In the first embodiment, the final locking portion 16 is separated from the temporary locking portion 15 and is independent. However, in this embodiment, the temporary locking portion 15 and the full locking portion 16 are integrally formed. It has become. That is, the locking portion 14 hanging down from the lower surface of the substrate 5 is formed to have a substantially U-shape in plan view, and the front surface (the front surface shown in FIG. 11) is the main locking portion 16. And the substrate 5
A final locking step 16B is formed in a stepped shape at a position closer to the height. On the other hand, slits 25 are formed on both side surfaces of the locking portion 14 from the rear end surface toward the main locking portion 16. Thereby, the outer surface of the both sides of the locking portion 14 in the range where the slit 25 is provided is
The temporary locking portion 15 that can bend inward with the 6 side as a base end.
Further, at the rear ends of the two temporary locking portions 15 and at substantially the same height position as the final locking step portion 16B, both the temporary locking step portions 15B are formed so as to protrude.

Although the guide member 3 can enter the space 26 at the center of the locking portion 14 through the accommodation hole 8 provided in the substrate 5, unlike the first embodiment, the bending of the temporary locking portion 15 is different from that of the first embodiment. There is no regulating function, and only a guiding function by the guide surface 21 is provided. Other configurations are the same as those of the first embodiment, and components having the same functions are denoted by the same reference numerals and description thereof is omitted.

Also in the second embodiment configured as described above, when the clip 1 is inserted into the mounting hole 13 while the guide member 3 is held at the primary locking position, the temporary locking portion 15 is bent and 13 and the provisional locking step 15B
As a result, it is engaged with the hole edge of the mounting hole 13 with elastic force. Thereafter, while the guide member 3 is strongly pushed in to shift from the primary locking position to the secondary locking position, the guide surface 21 is in sliding contact with the edge of the mounting hole 13, so that the entire clip 1 moves in the mounting hole 13. The locking step 16B is attached to the mounting hole 13
To the edge of the hole. As a result, in addition to the elastic locking by the two temporary locking portions 15 with respect to the mounting hole 13, the main locking step 16 </ b> B of the full locking portion 16 locks the clip body 2 undetachably. On the other hand, the same operation and effect as in the first embodiment can be obtained, such as obtaining a sufficient engaging force.

The present invention can be variously modified.
The following modifications are also included in the technical scope of the present invention. In any of the embodiments, the movement of the clip main body 2 in the mounting hole 13 is performed by the guide member 3, but may be performed by an operator's hand. In the first embodiment, the pair of the temporary locking pieces 15A is provided, but the number is not necessarily limited. In any of the embodiments, the insert body is integrated with the assist grip by insert molding after the molding of the clip body. However, the assist grip and the clip body may be simultaneously molded. That is, the clip of the present invention also includes a partial structure of an object to be fixed (for example, an assist grip). The assist grip may be formed by insert molding a hard member serving as a core along the longitudinal direction and a soft member wrapping the same, in which case the clip body is integrally formed with the hard member serving as the core. You may make it. The clip body and the assist grip may be connected via a hinge, and in this case, the assist grip can be made a folding type.
