Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a locking body of a stopper molded from plastic, and more specifically to a stopper used for fixing parts to the body of an automobile or a panel. In fasteners, etc. used when connecting panels facing each other, the base of these fasteners is inserted into a through hole in the body or panel in order to fix the base to the body or panel,
The present invention relates to an improved structure of a locking body which is a locking means for fixing the locking body.

As is well known, plastic fasteners, especially those used to fasten parts to the panel surface of automobiles and electrical products, usually have IC (IC) means for capturing the parts on one side of the base of the fastener. In addition, it is common to have a locking means on the other side that engages in a through hole in the panel and is fastened.

The number of catching means on one side of this fastener varies depending on the shape and nature of the parts, the purpose of the fastening, etc.
One-plane locking means can be roughly divided into two types. That is, one of them is V', a leg f is vertically disposed from the surface of the base body, a locking claw is derived from this leg, and the leg is inserted into a through hole in the panel. It locks onto the edge of the hole and attaches to it. An anchor-type locking body is a typical example.

In other types, the legs that hang down from the base are hollow, and the outer circumferential surface of these legs is provided with an enlarged diameter part, and the hollow part is used to fill the through hole of the panel. It is inserted while reducing its diameter, and when the insertion is completed, the enlarged diameter portion is restored and locked in the through hole.

The shape of each type of Jl, etc. varies slightly depending on the shape of the through hole, the strength of the locking force, etc., but the common feature between them is that the locking pawl has flexibility. The main leg of the locking body protrudes from the base body for a long time, or by providing a portion with an enlarged diameter on the outer circumferential surface.

Federation, a large space is prepared behind the panel that fixes the parts f'1. In cases where a single-V panel is connected to a panel assembly, the length of the legs is not an issue, and the focus is solely on workability and locking effect. For fj products, a large space is required behind the panel due to the installation location. It is often not possible to use fasteners with stiff long legs.

In this case, it is conceivable to shorten the metal piece as the W# deciding claw, but in the case of an anchor-type locking body, for example, in order to give the locking claw flexibility, it is necessary to give this V a certain length. Therefore, the word locking function itself, which simply shortens the length of the leg completely, is inhibited. This problem also occurs in a structure in which the inside of the leg is hollow and the leg is locked by a swollen portion provided on the outer circumferential surface.

For this reason, there has been a strong desire to develop a stopper that can shorten the entire length of the stopper without increasing the locking force and that can be adapted to narrow spaces behind the panel.

The present invention requires research and development based on the above-mentioned RN IC.
The purpose of this is to create a narrow space behind the panel in which the fasteners are to be secured. The object of the present invention is to provide a locking body that can ensure locking force, and furthermore, a locking body of a plastic pull-out tool that can be locked by simply pushing it into a through hole drilled in a panel in the same way as conventional fasteners. Our goal is to provide the following.

That is, in the present invention, a short and small support that exceeds the thickness of the panel to which the stopper is fixed is hung from the surface of the base of the stopper, and the support is maintained parallel to the base of the stopper from this support. This is a locking rod consisting of an extended elastic retaining arm with a joint, and when locking to a through hole drilled in a panel,
Insert the above-mentioned small supports and extend them in parallel to the surface of the base as part of this intrusion work.
! The base body is locked by passing the engaging arm (a) through the hole without bending it inwardly, and hooking the retaining portion provided on the arm to the edge of the hole.

The most physical structure of this locking body is ψj in the above explanation.
The elastic engagement arm extends smoothly from the support column.

Conventionally, the above-mentioned anchor-type locking body was
The locking means for the panel was an anchor-shaped locking pawl that extended toward the base from a leg hanging from the surface of the base.

This locking claw Q has a length of Yθ in the length direction of the leg to provide flexibility, and for this reason, the required length of the leg itself was inevitably required. In the invention, the elastic engagement arm (2) extends parallel to the surface of the base body, so it has a length along the surface of the base body. is sufficient to pass through the hole,
In other words, it only needs to be long enough to exceed the thickness of the panel.
Therefore, when it comes to locking into the through hole, there is enough space behind the panel to receive the support and elastic retaining arms.
＼It is possible to use it, and there is no need for a wide space between walls like in the past.

Next, all the embodiments of the present invention will be explained, and one feature thereof will be explained in detail.

In the drawings, Figs. 1 to 5 show an example in which the weather strip according to the present invention is attached to the trunk compartment or door opening of an automobile, and has been put into practical use using a clip. 1 indicates the base of the clip, 2t
3 is a locking arm that locks the entire weather strip A extending from one side edge of the base to one side (surface) la of the base; Reference numeral 4 indicates a panel, and reference numeral 5 indicates a hole drilled in the panel.The base 1 shown in 0C is a horizontally long rectangular plate, and the locking arm 2 is extended in a folded manner with the same width as its long side to form a space 6 between it and the base body 1 into which the piece a (iz) engages into the weather strip, and at the same time prevents C from being pulled out at its tip. A prevention claw 7 is provided.

On the other hand, the locking body 3 extending from the back surface 1b of the base has a support 8 that stands up vertically from the back surface, and an elastic retaining arm 9 that extends from the tip Q of this support in parallel to the back surface 1b from the M section. In this structure, the support column 8 is formed into a vertical wall and has two elastic engagement arms 9 extending in parallel from the top of both ends thereof,
The dorsal surface of each free tip of both elastic engagement arms, that is, the outer IJ
Engaging portions 10 and 10 are provided on the 111th surface, respectively. Further, a reinforcing lip 1 is extended from the center of the pillar 8 to the middle of the two elastic engagement arms (), 9, and the pillar 8 and the elastic retaining arm 9 are extended from the center of the pillar 8. 9 and the reinforcing rib Lifc to form a substantially E-shape.

The shape and dimensions of this cross-shaped locking body 3 are determined in accordance with the through-hole 5 formed in the panel 4, and the E-shape is selected here because it is the through-hole 5. This depends on the fact that the hole is a rectangular hole.

The relative relationship between the locking body 3 and the through hole 5 in which the locking body engages is exactly the same as in the conventional case, and there is no need to explain it here, but this implementation In the example, the through hole 5 is a horizontally long rectangular hole to match the overall shape of the locking body, and its short side zf is slightly longer than the width of the support column 8 of the locking body (the length of the vertical blade in the drawing). It is. In addition, in the locking body 3 itself, the length of the two elastic engagement arms 9 each extending from the column is made shorter than the width of the column 8. On the other hand, the column 8 is made of a panel. 4, and from the part exceeding this plate thickness, the elastic engagement arm 9 gold back side 1
A retaining portion 10 extends parallel to the elastic engaging arm 9 and forms a gap 12 between the elastic engaging arm 9 and the back surface lb of the base body, and protrudes from the free tip of the elastic engaging arm 9. A gap exceeding the thickness of the panel 4 is provided between the rear surface 1b of the base body and the back surface 1b so that the edge of the through hole 5 can be inserted between the gaps.

The clip related to the weather strip ψ is constructed as described above, and this clip is used to stop the weather strip. -T
f: Next, to explain, first the clip +)z
In order to cut the engagement piece a of the weatherstrip into the space 6 formed by the IP (2)
1 Relationship 1) Elastic restoring force of arm 2 and bite of claw 7 = J (
Therefore, attach this clip to the engagement piece of the IJ knob. Of course, since the well strip T is a long strip that can be stopped by 1 inch around the entire circumference of the door opening, a plurality of glue strips IJ-) can be applied at the required intervals using the same method. This means that 1+J will be added to each section.

After attaching the clip in this way, point it at the through hole 5 that will be made in the panel 4, such as the opening part of the door. Move the locking body 3 provided on the A side to the 1st position.
'S Push the entire locking body into this JA hole.

At C, as mentioned above, the column 8 has a width narrower than the short side Since the distance between the ends of the retaining parts 10 and 10 that are inserted toward the side is larger than the short side X, they once collide with the edge of the through hole, but
When is pressed against the panel Lnj, both elastic engagement arms 9, 9 are bent in the alignment direction (internal force), the retaining portion 10 passes through the edge of the through hole, and this elastic retaining arm 9° is pushed onto the back side of the panel. 9 is restored, it engages with the edge of the back side of the through hole, and JAllllll of the base body
b bites this edge and engages into the through hole 5.

As shown in Otsu, the locking body that locks the clitoris +7 is JC against the through hole.
The locking device is simply pushed in the iM direction, and it promises exactly the same workability as conventional locking devices of this type. Since the rising height from the back surface is slightly greater than the thickness of the panel, it is possible to secure the full locking even if the space behind the panel is narrow. In addition, in the drawing, there is a main body 3 behind the panel.
There is more than enough space available for all receptions, but
Is the large space here suitable for the present invention? However, it is not a necessary condition.

Furthermore, the locking body 3 of the present invention is bent along the surface direction of the back surface of the base body by utilizing the elasticity of the elastic engagement arm 9'fIC element extending parallel to the back surface of the base body. Yo υ, the engagement part I provided on this retaining arm.

The strength of the insertion force during insertion, the engagement force, and the magnitude of the removal force can be set arbitrarily by selecting the length and thickness of the engagement arm. be able to. In this case, even if the elastic engagement arm 9 may be lengthened in order to obtain flexible deflection, the actual height of the locking body 3 remains unchanged because the direction of extension is toward the back surface of the base body. , Therefore, the insertion depth at the time of engagement does not become large.

In addition, as in the embodiment described in AIJ, the length of the elastic engagement arm 9 including the thickness of the strut 8 of the locking body 3, and the lateral length of the entire locking body 3 are the shortness of the through hole 5. When the side length is smaller than X, the engaged state can be easily released by rotating the clinop by 90° in the engaged state.

That is, the clip is held in place by the engaging portion 1 provided on the elastic engaging arm.
0 to the edge of the through hole 5. However, since these elastic engagement arms extend in parallel along the back surface of the board, when the base 1 of the slider is rotated, the elastic engagement arms bend inward and deform while rotating this rotation. In particular, it is possible to rotate the direction of the locking body 3 by 90° inside the through hole 5 without imposing any excessive force.

Therefore, with this change in direction, the engaging part 10 comes off the long side line, and since the length of the elastic engaging arm 9 including the support column 8 is shorter than the length of the short side X, it can be easily pulled out from the through hole. This is possible.

By the way, when the present invention is applied to the locking body of the above-mentioned slope IJl, the height of this locking body becomes small, so when installing it on the weather strip Ai opening L1 part, it is necessary to Place the tip of the weather strip on the inner circumferential surface of the opening,
(Part 4a in Figures 4 and 5)
Next, when the locking body of this j'μ PC clip is inserted into the through hole 5 of the panel, the IJ tab can be fixed without getting caught between the panel 4 and the base 1 of the clip. Although the present invention has been described in detail in connection with the weather strip clip, the present invention can be carried out in the form shown in Fig. 6 and below. Something will happen.

Each of the embodiments shown in Figures 6 to 19 specifically shows only the guard (which is the main point of the present invention), and only the base of the stopper and the locking body are shown here. The explanation of means for capturing other parts that can be used is omitted. In each embodiment, the reference numeral 1 is used for the base body, the reference numeral 3 is used for the locking body, and V is used for the support of the locking body.
The elastic retaining arm is marked with 9, the engaging part provided on the elastic engagement arm is marked with 10, and the through hole into which this locking body engages is marked with 5. ing. Other supplementary additions in each embodiment No. 1. The parts that will be explained will be explained using new symbols each time. In addition, from Figure 6
