Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plastic clip that relatively connects a panel-like member and a bar-like member that are located parallel to each other.

The rod-like member is a general term that includes solid rods, tubular objects such as hollow pipes, and linear objects made of bundled electric wires, but the need to connect a panel-like member and a rod-like member in the above-mentioned relative positional relationship arises, for example, when attaching a decorative panel to the back of a bench-type seat in a van-type vehicle. That is, since a wire net made of steel rods or wires arranged in a crisscross pattern is incorporated in the back of such a seat, it is most convenient if the decorative panel can be attached to the rods (wires) that serve as the warp and weft of this net.

However, in the past, even in such cases, there were no clips suitable for attaching the decorative panel directly to the net component rod, so a separate metal plate with holes was prepared and this was attached first. This involved welding the decorative panel to the net, attaching it to the decorative panel, passing screws through the front of the panel, and screwing them into the holes in the metal plate, which was an extremely complicated process.

The present invention has been developed in view of the above, and provides an easy-to-form plastic clip that can directly engage and connect panels that are located parallel to each other and a bar-shaped member such as a rod. This eliminates the need for separate parts and troublesome work during finishing work such as. Of course, it goes without saying that once the proposed clip is disclosed, it is expected that it will be used for general purposes.

The clip of the first embodiment of the present invention will be explained below with reference to FIGS. 1 and 2. However, in this embodiment as well, the panel-like member P and rod-like member R to be attached are the decorative panel on the back of the vehicle seat and a single rod (indicated by the symbol N in Fig. 1) described earlier. In the illustrated case, the warp rod is used as an example, and although the panel P is generally fastened with main clips at multiple locations, only one location is shown as a representative.

The clip 1 has a head 2 that is applied to the front surface of the panel P, and a hanging portion 3 that hangs down from the head and projects to the back side of the panel through a through hole H drilled in the panel P. There is.

The shape of the hanging part 3 does not matter as long as it can pass through the through-hole H of the panel P, but in this case, the through-hole H is circular, and the outline of the maximum diameter part that just passes through it is also circular. . However, in order to prevent waste of material and to make the wall thickness as uniform as possible to avoid irregularities such as sink marks as a plastic molded product, the base portion of the hanging portion 3 near the head 2 is cut out 4. Of course, in principle, it may remain solid cylindrical.

A housing space 5 for a rod R (generally a rod-shaped member housing space) 5 is formed in the hanging portion 3 and is open at both sides facing each other in the diametrical direction and at the tip in the axial direction. A rod receiving groove 6 having a semicircular cross section and opening on both sides in the diametrical direction is further provided in the axially inner wall. Therefore, as will be described later, approximately half the circumference of the rod R will stably enter into this groove 6.

The axial tip opening edge portions (tip portions of the hanging portions 3) 7, 7 of the rod housing space 5 have rods that extend axially inward from the tip and taper radially inward. A pair of elastic holding pieces 8, 8 are provided to narrow the gap. The free ends 9, 9 of the elastic holding pieces hold down the outer peripheral surface of the rod R to prevent it from coming off after the installation work.

Further, an appropriate number of small engaging protrusions 10 are formed on the outer surface of the hanging part 4, but this is done after the main clip 1 has been engaged with the panel P in advance, and then the clip is attached to the rod R. This is to enable work in the engagement procedure.

Below, we will continue to explain this installation process.

First, the hanging part 3 of this clip is inserted into the through hole H of the panel P from its tip. As a result, the small engagement protrusion 10 provided on the outer surface of the hanging portion can be
It passes through the through hole H of the panel P forcibly and is located on the back edge side of the through hole H, pushing the panel P from both sides between it and the head 2 of the clip 1. 1 means that it is temporarily fixed.

After doing this, bring the panel closer to the rod R and press the head 2 of the main clip 1 from the front side of the panel to remove the main clip 1 protruding from the back side of the panel.
Press the tip of the hanging part 3 against the rod R.

Then, the base of a pair of elastic holding pieces 8, 8 at the hanging portion 3, which gradually narrows the entrance of the rod accommodating space 5 toward the back, comes into contact with the rod R. If pressure is subsequently continued, the elastic holding pieces 8, 8 are bent radially outward by the rod R, and the rod R passes through the gap between the pair of elastic holding pieces 8, 8 relatively (of course,
In reality, it is the clip that advances), and when the rod R eventually fits exactly into the accommodating space 5, particularly into the accommodating groove 6 in the illustrated embodiment, as planned, the maximum diameter portion of the rod as viewed in the direction of advancement exceeds the free ends 9, 9 of the elastic holding pieces 8, 8, and therefore the elastic holding pieces return to their original shape due to the repulsive force from having been bent up until then, and the free ends 9, 9 begin to press against the outer peripheral surface of the rod R.

In this way, the rod R and the panel P are inseparably engaged with each other, and the intended working purpose is achieved.

Of course, the dimensions of each part are designed to satisfy the above functions. Below, we will discuss incidental considerations.

The head 2 of the clip 1 can have any shape, but in this embodiment, it is shaped like a disk and a suction cup, so that after installation is completed, the head 2 of the clip 1 is in close contact with the panel surface to achieve watertightness. ing. Further, the surface of the panel P where the head 2 of the clip comes into contact is notched to prevent the head of the clip from unnecessarily protruding outward.

By the way, if the rod R is forcefully inserted into the accommodation space 5 and the rod R is slightly prevented from coming out, the backs of the holding pieces 8, 8 should be made solid, that is, the holding pieces 8, 8
It is also possible to make the clip non-movable, but this would make the clip less versatile. For example, if the rod R is a part of the net N, which is the object of attachment in this embodiment, this net has elasticity as a whole, and therefore the rod R itself is likely to move in a direction perpendicular to its own axis. There is. Therefore, when the clip 1 is pressed against this rod, the holding pieces 8, 8 must be able to move easily.
Rod R escapes, making it impossible to connect the clip and rod. On this point, if the holding piece is made with a free tip as in this proposal, the design of its wall thickness and dimensions makes it easy to set a force field condition in which the holding piece bends before the force pushing the rod in the direction of release. It can be done.

Moreover, once the rod is bitten, when the rod R tries to get out, the holding piece swells up and becomes deformed, narrowing the entrance even more.
This also has the advantage of not letting you escape easily.

Further, the small engagement protrusion 10 is effective for temporarily fixing the main clip 1 to the panel P.

For example, in the case of the application envisioned above, it is not necessary to first apply the panel P to the metal net N in which the rods are assembled in parallel cross-sections, and then insert the clips 1 into each of the through-holes H. , would be practically impossible or irrational. This is because the person holding the panel P and the person attaching the clips must be completely separated in labor, or a large number of workers are required.

On the other hand, if the clip 1 can be temporarily fixed to the panel P as in the present invention, it may be possible to work by one person depending on the situation, and if the panel is actually large and two or three people are required, However, compared to conventional work, the work is definitely easier.

Moreover, it is extremely practical for this kind of application.
The panel engaging member that has a reasonable effect is formed on the outer surface of the opposite side of the hanging part 3 where the elastic holding piece 8 that holds the rod is provided, so that the hanging part 3 can be engaged with both sides. Since it is commonly used to support the mating parts, there is really no waste in the clip structure.

However, as an engaging member for the panel P, instead of the small engaging protrusion 10 shown in FIGS.
As shown in the clip 1 of the illustrated embodiment, for example, a pair of full-scale fanatic devices may be provided on the outer peripheral surface of the hanging portion 3. In this way, it can also be used as a so-called hole plug. That is, the structure of the so-called plastic fastener for engaging the panel may be used as the fastener device. Elastic arm pieces 11, 11 whose diameter gradually expands toward the front are extended, and their free ends serve as engaging surface portions 12, 12 which are hooked onto the back edge of the through hole H of the panel P. Of course, the temporary fixing work to panel P is done using elastic arm piece 1.
Snaps 1 and 11 are forced into hole H.
This is in-work.

As described above, according to the present invention, two members that are difficult to join, such as a panel and a rod, can be joined by simply pushing the clips together without requiring a complicated structure on the rod-shaped member side as in the past. Moreover, the insertion force can be arbitrarily designed, and even if the insertion force is small, the resistance to pull-out can be high, so that an extremely versatile clip can be provided for this type of joining.
