Description

[Detailed description of the invention] This invention relates to a holder that holds a molding (also referred to as a wind molding for convenience) that is attached to the periphery of a window glass of an automobile. , which is assembled between the window glass installed in the window frame section and holds the window molding, and the window frame section is provided with an adhesive means (for example, double-sided tape) and an elastic narrowing means. The present invention relates to a holder that is adhesively fixed using reaction force (pressure force) when a pressing piece that can change to an expanded state is pressed against an end surface of a window glass.

This type of holder, also called a molding clip, has traditionally been made of metal or synthetic resin that has been molded as a single item, but the former suffers from electrolytic corrosion with the body (window frame) and expansion of the pressing part. In order to prevent damage to the end surfaces of the window glass and noise generation, expensive and time-consuming resin coating is required. In addition, in the latter case, in order to strengthen the adhesion force to the window frame and the pressing force to the window glass, the overall size tends to be increased, and in order to avoid deterioration of holding performance due to creep, it is necessary to hold the pressing part for a long time. Rather, it is not permissible to store it in a closed state and there are restrictions on its handling. There were other problems.

The present invention is a compound holder consisting of a single molded outer clip made of synthetic resin (including rubber) and an inner clip made of metal. It is possible to eliminate such drawbacks, maintain the holding function stably over a long period of time, and perform it appropriately.

The present invention will be explained below based on examples.

[First Example] In the holder of this example shown in Figs. 1 to 3, an outer clip C ₁ installed in the glass receiving frame part B of the body
The inner clip _C2 , which is incorporated into the outer clip _C1 and reinforces the clip, is made of a thin metal material with an appropriate elasticity. It is more press molded. The outer clip C ₁ has a horizontally rectangular substrate 1 having a side cross section, and has two U-grooves 2 in the center thereof to protrude a hook piece 3 for the molding M, and a pair of pressing blades at both ends of the substrate 1. Piece 9 is formed by bending. Board 1
A double-sided tape 4 that adheres to the inner surface of the receiving frame portion B is attached to the outer surface of the hook piece 3, and a housing portion 5 for assembling the inner clip is formed on the inner surface of both 1 and 3. Furthermore, on the upper edges of both sides of the board 1, there are locking edges _1a for the flange portion F1 of the molding M.
is formed. Reference numeral 6 denotes locking claws formed on the side edges of each U-groove 2, both of which protrude toward the hook piece 3.
The hook piece 3 is elastically deformable in the outward and outward directions of the board 1, and has a flange portion of the molding at its upper end.
A receiving portion 7 for F ₁ is formed, and a claw portion 8 that can elastically engage with the flange portion F ₁ is formed at the lower part of the receiving portion 7 to protrude outward and form a series of guide curved surfaces with the receiving portion 7 .

Both of the pressing blades 9 are cantilevered from the end of the substrate 1 via a connecting portion 10, and can be elastically deformed in the inward/outward (opening/closing) direction and the up/down direction with respect to the substrate 1. An engaging edge 11 for the window glass G is formed along its lower edge, while a contact portion 1 that cushionably abuts against the end surface of the window glass G is provided at the free end.
2, an engaging portion 13 for the flange portion F ₁ is formed at the upper end of the contact portion 12, and a hook portion 14 for the locking pawl 6 is formed at the lower end. Reference numeral 15 denotes an engagement edge formed along the upper edge of each wing piece 9, which can engage and hold the elastic wing piece 19 of the inner clip _C2 . In addition, when the wing pieces 9 are free, they are in a state where they are spread out from each other in a V-shape, and the locking pawl 6 and the hook portion 14
It is held in a narrowly closed state opposite to the substrate 1 by using. Further, the engaging portion 13 is set at a position lower than the receiving portion 7 of the hook piece 3 and higher than the claw portion 8. On the other hand, the locking pawl 6 and the hook portion 14 can be engaged mainly when the wing piece 9 is pushed in, and can be separated when the wing piece 9 is pushed down appropriately.

On the other hand, the inner clip C ₂ is molded in a shape and size that matches the accommodating portion 5 of the aforementioned outer clip C ₁ , and uses two U grooves 17 in the center of the base plate 16 to reinforce and support the hook piece 3 . A pair of elastic wings 19 are formed on both sides of the substrate 16 by punching. Both wing pieces 19 are in strong pressure contact with the end face of the window glass G via the pressing wing piece 9, and are curved to bulge toward the substrate 16 and narrow in width toward the free end. It extends in a cantilevered manner from the connecting base 20, and can be deformed by exerting an effective elastic force from a narrowed closed state in contact with the substrate 16 to an expanded V-shaped state away from it.

In the holder of this example, both the clips C ₁ and C ₂ configured as described above can be stored separately, and when carried out, the outer clip C ₁ is used as shown in FIG.
Insert and set the inner clip C ₂ into the inner clip C 2 , and push in both pressing wing pieces 9 and 9 to lock the hook portion 14 into the locking pawl 6 .
is engaged with the elastic wing pieces 19 to be elastically held in a narrowly closed state. In this state, as shown in FIG. 3A, the substrate ₁ of the outer clip C1 is adhesively fixed to a predetermined position on the inner surface of the receiving frame part B via double-sided tape 4. After that, the inner and outer flange parts F ₁ and F ₂ of the molding M
Align it with the receiving part 7 of the hook piece 3 and the outer surface of the window glass G installed in the receiving frame part B, and push it in the direction of the arrow.

As a result, as shown in Figure B, at Mall M,
Using the inward deformation of the hook piece 3 and the elastic support piece 18, the flange part _F1 is guided by the receiving part 7 and engaged with the claw part 8. On the other hand, in the holder, the above flange part F ₁
contacts the engaging portions 13 of both pressing blades 9 and elastically pushes down the free end side together with the elastic blades 19, so that the pressing blades 9 lock the locking pawl 6 just before the molding is locked. When the portion 14 is disengaged, it is expanded under the elastic force (pressure force) of the elastic wing 19, and as shown in FIG. The engaging edge 11 is brought into contact with the lower surface of the edge of the glass by pressure contact without any generation.

As a result, as shown in FIG. , the contact portion 12 of the pressing wing 9 is strongly pressed against the window glass by the stress caused by the deformation of the wing 19, and the reaction force at that time is used as a pressing force to apply pressure to the substrate 1,
16 is effectively received and pressed against the inner surface of the receiving frame part B,
Reaction force when attaching the molding, that is, hook piece 3, elastic support piece 1
Even if the force acting in the peeling direction of the substrate 1 due to the deformation of the substrate 8 is absorbed and offset, the pressure is firmly bonded with an effective pressing force that is still in excess, and the engaging edge 11 is used to push the substrate 1 upward (outward). fluctuations are also actively prevented. With such a holder, the molding M is moved so that the outer flange part _F1 , which is locked to the claw part 8, faces the receiving frame part B side under the stress of both pieces 3 and 18 mentioned above, and the inner flange part _F2 is moved to the outer surface of the window glass G. They are firmly pressed against each other to be fixed and held in the normal position at the required height. In the holder of this embodiment, one of the clips may be provided with means (for example, a locking piece or a protrusion) to prevent the inner clip from falling off when the inner clip is set.

[Second Embodiment] In the holder of this embodiment shown in Figs. 4 to 6, the outer clip _C1 is made of hard synthetic resin, and the inner clip _C2 is molded from a metal wire (spring wire). In the outer clip C ₁ , the side cross section [shaped horizontally rectangular substrate 1
Regarding the pair of pressing blades 9 bent from both ends,
They have a curved shape that bulges out toward the substrate 1 and narrows in width toward the free end, so that when they are free, they are in a V-shaped expanded state. The rest of the structure is the same as that of the preceding outer clip _C1 , so the same or equivalent parts are given common reference numerals and their explanation will be omitted. Note 1b
is an engaging protrusion formed in the center of the substrate 1, which engages and holds the base rod 16' of the inner clip _C2 . 11,1
5 is a missing number.

The inner clip _C2 set in the above-mentioned outer clip _C1 is made by bending a single wire, and has an elastic support rod 18' for the hook piece 3 formed in the center of the base rod 16'. A pair of elastic wing rods 19' are bent in a cantilever shape from connecting rod portions 20' which are vertically bent at both ends of the base rod 16'. This wing rod 19' is the base rod 1
It has a curved shape that bulges out toward 6', and can effectively deform from a narrowed state to an expanded state. Note that a locking rod portion 19'a for the corresponding pressing blade piece 9 is formed at the free end of each blade rod 19'.

In the holder of this example, when assembling the inner clip _C2 to the outer clip _C1 , as shown in FIG. While engaging and holding along the lower part, both connecting rod parts 20' are held in the connecting part 10, and the locking rod part 1 of the elastic wing rod 19'
It is possible to set the pressing blade 9'a in a state where it is locked to the inner surface of the free end portion of the pressing blade 9 to prevent it from falling off. Then, both pressing wing pieces 9 are pushed in, and the hook portion 14 is engaged with the locking pawl 6, thereby holding it in a narrowly closed state together with the elastic wing rod 19'. In such a state, similar to the previous example, the process can be carried out as shown in FIGS. 6A and 6B based on the steps of installing the holder on the window frame B and pushing the molding M into the holder.

As a result, in the holder of this example, the elastic wing rod 19'
By effectively absorbing variations in the distance between the window frame portion B and the window glass G using the variable range of , the contact portion 12 of the pressing blade 9 is
is strongly pressed against the end surface of the window glass in a cushioning manner, and the reaction force absorbs and cancels out the reaction force when the molding is attached, and the board 1 is crimped and fixed on the inner surface of the receiving frame part B, and the molding M is firmly held in its normal position. In the holder of this example, an engaging portion for the window glass may be attached to the pressing wing piece 9 or the elastic wing rod 19'.

In either the first or second holder, a sawtooth-like engaging portion may be formed on the outer surface of the substrate 1 of the outer clip _C1 , whereby the pressing force against the receiving frame portion B will cause the substrate 1 and the double-sided tape 4 to bite into and engage with each other, making it possible to actively prevent the substrate from peeling off from the tape and even the entire holder from moving outward.

As described above, the holder of the present invention consists of an outer clip made of synthetic resin or rubber that is attached to the window frame of an automobile body, and an inner clip that is set inside the clip, and both clips are assembled together. The pressing blades and the elastic wings are once held in a narrowly closed state and adhered to the inner surface of the window frame, and during the process of pushing the molding, the molding is elastically engaged with the hook of the outer clip. Then, the pressing wing pieces and the elastic wing part in the narrowed state are made to act in the expanded state, and the elastic wing part strongly presses the abutting part against the end surface of the window glass, and the pushing force due to the reaction force is used to hold the outer clip. The tool can be firmly crimped onto the receiving frame and the molding can be stably held for a long time.

In such a holder, the inner clip is set in the outer clip as if covered and housed, and the inner clip is isolated from the receiving frame and the molding, thereby eliminating the occurrence of electrolytic corrosion. In addition, since the elastic wings of the inner clip do not contact the end surface of the window glass directly, but instead press the pressing wing pieces of the outer clip as cushioning pieces, even if the pressing force of the wing parts is strengthened, the end face of the window glass will not be damaged. It is possible to eliminate the generation of abnormal noise when contacting. As a result, the ability of the holder to press against the window glass can be safely increased. Furthermore, although the holder of the present invention is composed of two clips, each clip can be molded separately, it can be handled and stored in either the closed or expanded state without any loss of function, and it can be held The tool itself can be constructed to be substantially the size of the outer clip, and from the overall viewpoint, it can be made cheaper and smaller than the conventional clip mentioned above.
