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 by using a mounting hole opened in a mounting surface of a body or the like. Some of such clips include a pair of leg pieces that are locked to the mounting holes. The two leg pieces are provided with elasticity so as to squeeze and deform when passing through the mounting hole, and the locking step formed at the base thereof returns when passing through the mounting hole and returns to the edge of the mounting hole. To be locked.

[0003]

However, in the above-mentioned method, the elasticity of the leg pieces obtains the engaging force with respect to the equipment. Since the direction in which the leg piece is fitted and the direction in which the leg piece is pulled out coincide with each other, the reliability of the engagement may not be sufficient particularly when a force acts in the removal direction such as an assist grip. An object of the present invention is to provide a clip that can increase the reliability of attachment to an object to be fixed.

[0004]

According to a first aspect of the present invention, there is provided a clip made of resin for fixing an object to a mounting surface having a mounting hole. A clip body comprising a base to which the fixed object can be attached and through which the mounting hole penetrates, a leg hanging down from the base and insertable into the mounting hole, and a guide member which can be inserted into the mounting hole, A part of the leg portion is provided with a main locking portion, while an inclined surface is formed at a tip portion of the guide member, and the inclined surface is formed in the mounting hole when the guide member is inserted into the mounting hole. The permanent locking portion is guided toward the hole edge so that the final locking portion is inelastically locked to the hole edge of the mounting hole as the sliding portion comes into sliding contact with the hole edge. It is. According to a second aspect of the present invention, in the first aspect, the leg portion includes:
At least one pair of leg pieces which can be inserted into the mounting hole independently of the main locking portion while being narrowed and deformed are provided, and both the leg pieces are provided with the main locking portion with respect to a hole edge of the mounting hole. A provisional locking portion that elastically locks from a direction different from the locking direction of the portion is provided, while the guide member is cut between the leg pieces from the mounting hole to thereby enter the respective leg pieces. It is characterized in that deformation in the direction of stenosis can be restricted. According to the third aspect of the present invention, in the second aspect, between the guide member and the clip body, the guide member is inserted shallowly between the leg pieces to reduce the stenosis. A temporary locking position for locking the clip body in an allowed state, and a full locking position for locking the clip body in a state of deeply entering between the legs and restricting the stenosis. It can be held at a position.

[0005]

According to the first aspect of the present invention, the leg is inserted into the mounting hole of the mounting surface after or before mounting the object to be fixed to the base. Thereafter, the guide member is inserted into the mounting hole. During this insertion, the inclined surface of the guide member slides on the hole edge of the mounting hole, so that the clip body moves in the mounting hole such that the final locking portion is locked on the hole edge of the mounting hole. In this way, since the main locking portion of the leg is hooked on the hole edge of the mounting hole, the clip body and, consequently, the object to be fixed are prevented from coming off with respect to the mounting surface. At this time, since the main locking portion is inelastically locked to the hole edge of the mounting hole, even if a strong force acts on the fixed object in the removal direction, it is sufficient for this. Can withstand.
According to the invention of claim 2, each leg piece is inserted into the mounting hole while being narrowed and deformed independently of the main locking portion, and the temporary locking portion is elastically attached to the hole edge of the mounting hole. Lock. Thus, the fixed object is temporarily fixed to the mounting surface before the guide member is mounted. After that, when the guide member is inserted into the mounting hole, the main locking portion is locked to the hole edge of the mounting hole by the guidance of the inclined surface, and the guide member is split between the leg pieces, so that each leg piece is inserted. Since the constriction deformation of the leg portion is restricted, the leg portion is securely locked to the mounting hole by the non-elastic locking of the two locking portions, the main locking portion and the temporary locking portion. According to the third aspect of the present invention, the guide member can be held at the temporary locking position with respect to the clip body so that the two are integrated. Therefore, even if each leg is inserted into the mounting hole while the guide member is mounted, each leg passes through the mounting hole while being narrowed, and is temporarily locked. If you push the guide member to a deeper position, the guide member will reach the final locking position,
The swelling of each leg is regulated, and the final locking portion is locked at the same time. As described above, according to the third aspect of the present invention, the guide member can be integrated with the clip body in advance, so that the workability is excellent.

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, a case will be described in which the present invention is applied to a clip C for attaching an assist grip A (an object to be fixed) of an automobile. FIG.
As shown in (1), the assist grip A is attached via a clip C at a position near the side glass G on the roof surface at the rear of the vehicle. However, a so-called molded ceiling is used for the roof surface. As shown in FIG. 7 and the like, the molded ceiling has a roof head lining R having good elasticity, and the clip C passes through the hole Ra of the roof head lining R, and is formed in a square hole provided in the roof panel P. The assist grip A is mounted by being inserted into the mounting hole 1 having a shape.

The assist grip A is formed in a substantially U-shape as a whole by a synthetic resin material, and a clip C (clip body 2) for mounting is embedded at both ends by insert molding. However, a window 3 is opened at the end surface of the assist grip A, and the upper surface of the clip body 2 is exposed at the bottom surface thereof, and a guide member 4 described later can be inserted therefrom.

[0008] The clip C comprises a clip body 2 and a guide member 4 inserted into the clip body 2 both formed of a synthetic resin material. First, starting from the clip body 2, the upper part of the clip body 2 is a base 5 embedded in the assist grip A. The base 5 includes a substrate 5a formed in a rectangular shape, and an upper plate 5b and a lower plate 5c sandwiching the substrate 5a from above and below and formed smaller than the substrate 5a. Thus, the upper and lower plates 5b,
The reason why the step 5c is formed with a step around the entire periphery of the substrate 5a is to mechanically prevent the assist grip A from coming off.

A mounting hole 6 into which the guide member 4 can be inserted is provided in the upper surface of the base 5 so as to penetrate from the upper plate 5b to the lower plate 5c. In this embodiment, the mounting hole 6 includes a retainer insertion portion 6a for inserting a retainer piece 7 of the guide member 4 described later, and a guide insertion portion 6b for inserting the guide piece 8 therethrough. (FIG. 3
reference). The retainer insertion portion 6a has two openings arranged in parallel at substantially the center of the upper plate 5b with an interval therebetween, and communicates with the inside of the leg 9 described below. Further, the guide insertion portion 6b has a longitudinal direction in a direction orthogonal to the retainer insertion portion 6a, and has two openings arranged in parallel at an interval like the retainer insertion portion 6a.

On the other hand, on the lower surface of the lower plate 5c of the base 5, legs 9 for mounting to the roof panel P (mounting surface) are provided.
Are hanging down integrally and can be inserted into the mounting hole 1. The lower end of the leg 9 is formed in a downwardly facing truncated pyramid shape, and the upper side thereof is formed in a substantially prismatic shape.
A pair of retainer housing portions 10 communicating with the retainer insertion portion 6a are perforated to a predetermined depth in the leg portions 9.
Leg pieces 11 are provided on the outer surfaces of the legs 9, respectively, on the surfaces facing the long sides of both retainer housing portions 10. The two leg pieces 11 can be bent in the direction of constriction by making cuts S in a downward U-shape so that the outer surfaces of the leg parts 9 communicate with the retainer housing part 10. In the natural state, the portions near the free ends of both leg pieces 11 are temporary locking portions 12 slightly projecting from the outer surfaces of the leg portions 9, and when the leg portions 9 are inserted into the mounting holes 1, the leg pieces 11 are moved. It is narrowed and deformed so as to be retracted toward the retainer accommodating portion 10 to allow insertion into the mounting hole 1. It is designed to stop.

Further, the outer surface of the leg 9 and the two leg pieces 11
On one surface orthogonal to the direction of swelling, a permanent locking portion 13 is formed by being stepped down along the width direction of the leg portion 9. When the leg portion 9 is inserted into the mounting hole 1, the main locking portion 13 can pass without interfering with the edge of the mounting hole 1, and will be described in detail later.
When the clip body 2 moves in the mounting hole 1 by the insertion of the mounting hole 1, the clip main body 2 can be inelastically locked to the hole edge of the mounting hole 1.

Further, a pair of spacer pieces 14 are hung on the lower surface of the lower plate 5c. One of the spacer pieces 14 is provided above the main locking portion 13 along the length direction thereof, and the other is provided to face the opposite side. The two spacer pieces 14 abut against the upper surface of the roof panel P when the leg portions 9 are inserted into the mounting holes 1, so that the base portion 5 has the thickness of the roof head lining R.
To prevent the roof head lining R from being crushed. It should be noted that lightening portions 15 and 16 are formed on the bottom surface of the base portion 5 and the side surface on the side where the main locking portion 13 is provided, respectively.

Next, the guide member 4 will be described. The upper surface of the guide member 4 is a substantially rectangular pressing surface 17, and a pair of retainer pieces 7 are suspended in parallel at the center of the lower surface. I have. Both the retainer pieces 7 can be accommodated in the retainer accommodating section 10 through the retainer insertion section 6a, and at this time, the bending of the leg pieces 11 can be restricted by being opposed to the back surfaces of the two leg pieces 11. Further, a pair of guide pieces 8 are suspended in parallel in a direction orthogonal to both the retainer pieces 7 near the end of the lower surface of the pressing surface 17 and can be inserted into the guide insertion portions 6b of the clip body 2 respectively. It is. As shown in FIG. 5, two locking projections 18a and 18b are formed on the opposite side edges of the two guide pieces 8 so as to project upward and downward. The projections 18a, the upper ones are locking projections 18b for secondary locking. Each of these can be selectively locked with the opening edge of the lower plate 5c of the guide insertion portion 6b, and the guide member 4 is prevented from falling out of the clip main body 2 even when locked at any position. Can be held. However, when the locking projection 18a for primary locking is locked with the opening edge of the guide insertion portion 6b,
The two retainer pieces 7 are at a height position that allows the leg piece 11 to squeeze and deform. However, when the locking projection 18b for secondary locking is locked to the opening edge, the retainer piece 7 is located on the back side of the leg piece 11 and the height for restricting the squeezing deformation of the leg piece 11 is set. Position.

The surfaces of the guide pieces 8 facing the base 5 are arranged to slide along the side surfaces of the base 5 when the guide member 4 is inserted into the mounting holes 6.
Further, a rib 19 having a predetermined length is provided along the length direction on a surface of the both guide pieces 8 opposite to the side in contact with the base portion 5 so as to reduce insertion resistance. An inclined surface 20 is formed on the more distal end side.
The inclined surface 20 slides on the hole edge of the mounting hole 1 with the insertion of the guide member 4, thereby moving the clip body 2 so that the main locking portion 13 is locked on the hole edge of the mounting hole 1. be able to.

Next, the operation and effect of this embodiment configured as described above will be specifically described. The clip body 2 is embedded at both ends of the assist grip A, and the leg 9 and the spacer piece 14 are exposed in this state. Also,
Prior to fastening to the molded ceiling, the guide member 4 and the clip body 2 are integrated. That is, the retainer piece 7 of the guide member 4 is inserted into the retainer insertion portion 6a, and the two guide pieces 8
Into the guide insertion portion 6b.
When the guide member 4 is inserted to a predetermined depth, the primary locking engagement projection 18a is engaged with the lower opening edge of the guide insertion portion 6b. Is done.

The both ends of the assist grip A are applied to the mounting portions of the molded ceiling. That is, in this installation site, in the roof head lining R of the molded ceiling,
A hole Ra is opened in alignment with the mounting hole 1, and the leg 9 is inserted through the hole Ra. At this time, both the retainer pieces 7 are only slightly inserted into the retainer accommodating portion 10 at the tip ends, but do not reach the leg pieces 11. Therefore, the leg portion 9 passes through the mounting hole 1 while constricting and deforming the two leg pieces 11, and when the leg piece 11 returns through the mounting hole 1, the temporary locking portion 12 moves to the edge of the mounting hole 1. Elastically locked to As a result, the assist grip A is temporarily fixed to the roof panel P, but is held with a sufficient engaging force to be held by the roof panel P without being supported by a worker.

In this state, when the guide member 4 is pressed strongly by pressing the pressing surface 17, the locking projection 1 for primary locking is pressed.
8a is released, the two retainer pieces 7 penetrate deeply into the retainer accommodating portion 10, and the secondary locking engagement projections 18b
Locks on the opening edge of the guide insertion portion 6b. As a result, the two retainer pieces 7 reach the back side of the two leg pieces 11, and as a result, the deformation of the two leg pieces 11 in the constriction direction, that is, the mounting hole 1.
The deformation in the direction of dissociating from the hole edge is restricted. At the same time, since the inclined surfaces 20 of the two guide pieces 8 are in sliding contact with the edge of the mounting hole 1, the clip body 2 moves within the mounting hole 1, and the final locking portion 13 is moved to the edge of the mounting hole 1. Inelastically with respect to.

Thus, since the deformation of the two leg pieces 11 in the disengaging direction is restricted, the engaging force between the temporary locking portion 12 and the edge of the mounting hole 1 is increased. Further, the main locking portion 13 is locked in a direction orthogonal to the locking direction of the temporary locking portion 12, and the main locking portion 13 is a high rigid portion in which the leg 9 has a sufficient thickness. , A high engaging force can be obtained.
Therefore, it is an extremely effective one in a case where a strong force acts in the pulling-out direction like the assist grip A.
