Description

DETAILED DESCRIPTION OF THE INVENTION This invention is used for attaching and detaching round rod-like objects (hereinafter referred to as "round rods") with various diameters to and from a support plate, and is molded from a synthetic resin having rigid elasticity. Regarding holding clips.

As this type of holding clip, for example, the following type disclosed in West German Patent Application No. 2816181 is well known.

A first arcuate part having rigidity and a second arcuate part having spring elasticity are formed on both sides of a storage chamber in which a round rod is formed on both sides of the bottom plate, which is provided with a fitting protrusion below which fits into the mounting hole of the support plate. The upper end of the first arcuate part extends around the upper side of the storage chamber, and the tip thereof is provided with a presser finger, and the upper end of the second arcuate part extends into the storage chamber. The spring arm is protruded,
It is equipped with an arcuate holding finger-like portion at its tip.

In the usage mode, the round bar is pushed into the V-shaped introduction passage formed between the upper end of the first arcuate part and the spring arm, and is held between the holding fingers and the presser fingers. At this time, the introduction passage widens as the second arcuate portion 5 moves in the lateral direction, and closes immediately after the round bar passes through.

This clip allows the round bar to be easily assembled and has good holding power in the direction of the first arcuate part. On the contrary, the round bar can be easily pushed in in the direction of the second arcuate part and can also be easily removed. Therefore, since it has only a small holding force in the direction of the second arcuate portion, the round bar will pop out of the clip even if a very slight tension is applied. Also, the fact that the second arcuate part has only a small pressing force means that when a round bar with a small diameter is inserted,
In particular, the round rod is held only in a relaxed state and is free to move, causing problems such as swinging or shaking.

In view of the above, the present invention provides a clip of the above type with a strong holding force also in the direction of the second arcuate part, so that the round bar does not fly out due to tension or other external action. The purpose is to provide a retaining clip.

Another object of the present invention is to provide a holding clip of the above type that is capable of supporting the round bar well even on the bottom plate.

The gist of the invention is that a first arcuate part having rigidity and a second arcuate part having spring elasticity extend from both sides of a bottom plate having a protrusion for mounting on a support plate into a housing chamber for a round bar. The upper end of the first arcuate part extends around the upper side of the storage chamber, and the tip thereof is provided with a presser finger-like part, and the upper end of the second arcuate part extends into the storage chamber. the spring arm is protruded;
In the holding clip, which has a holding finger at its tip and a V-shaped introduction passage is formed between the upper end of the first arc and the spring arm, the presser arc is directed toward the center of the storage chamber. At the same time, the surface that contacts the round bar at the tip thereof is a concave curved surface facing the maximum diameter of the round bar, and further between the lower half of the inner wall of the second arcuate part and the holding finger at the tip of the spring arm, It consists of a retaining clip equipped with a support web that acts as a pressure-resistant material.

Hereinafter, embodiments of the present invention will be described based on illustrated examples.

The retaining clip shown in the figure is molded from a rigid-elastic synthetic resin and is used to hold round rods of various diameters, cables, and brake pipes on a single support plate, especially an automobile body sheet metal. It is used to attach and detach round rod-like objects such as.

This retaining clip consists of the following parts: That is, one bottom plate 1 has a fitting protrusion 2 on the lower surface that can be elastically fitted into a fitting hole of a support plate 3, and a C-shape rising inward from one side of the bottom plate 1. It consists of a first arcuate part 4 which is rigid and difficult to bend, and a second arcuate part 5 which is elastic and can move like a spring, rising inward from the other side of the bottom plate 1. Upper end 4 of first arcuate part 4
A extends around the upper side of the housing chamber 6 for the round rod 17. Further, a spring arm 7 projects into the storage chamber 6 from the upper end 5a of the second arcuate portion 5, and has a holding finger portion 8 at the tip end of the spring arm 7. The holding fingers 8 are bent in the same direction as the first arcuate part 4 and upward in order to grip the round bar 17.

The upper end 4a of the first arcuate part 4 and the spring arm 7 form a narrow upward V-shaped introduction passage 9.Therefore, the second arcuate part 5 and the spring arm 7 form a round bar 17. When the round rod 17 is pushed in, it moves sideways and once escapes, and after the round rod 17 passes through the introduction passage 9, it immediately returns to its original position due to its elasticity (see Fig. 2).

At the upper end of the first arcuate part 4 a short presser finger 14 is attached facing towards the center of the receiving chamber 6. The contact surface 15 with the round bar is formed into a concave curved surface corresponding to the diameter of the round bar 17 having the largest diameter. When the round bar 17 is introduced into the storage chamber 6 with this configuration, the presser fingers 14 are inserted into the round bar 17.
The round bar 17 is pressed and held toward the axis with an inscribed circle relationship, and the round bar 17 is not easily rolled and is held stably. To facilitate pushing the bar after passing through the narrow passage, the presser fingers 14
As shown in the figure, it is attached to the first arcuate part 4 at an attachment part 16 which has a weakened cross-section.

In order to prevent the accommodated round rod 17 from automatically flying out of the receiving chamber 6 in the direction of the resilient spring arm 7, the lower half of the inner wall of the second arcuate part 5;
A support web 10 is provided between the spring arm 7 and the holding finger 8 at the tip thereof, which acts as a pressure-resisting member. In the embodiment shown in FIGS. 1 and 2, this support web 10 is mounted with spring elasticity at the transition from the base plate 1 to the second arcuate part 5. On the other hand, the tip 12 of this support web 10 ends at a free end, which is free to move downwards, at some distance from the bent retaining fingers 8.

The holding fingers 8 are located on the extension line of this support web 10.
One protruding step part 11 is formed at the beginning of the protruding step part 11. When the round bar 17 is pushed into the protruding step part 11, the elastic second arcuate part 5 first becomes a spring-like arm. By moving laterally with 7 and escaping, it is pulled up onto the support web 10. Then, when pushing the round rod 17 further, the support web 10 is pressed downward, and finally the round rod reaches the storage chamber 6 and is restrained between the holding finger 8 and the presser finger 14. During the installation, the protruding step 11 is stopped in front of the tip 12 of the support web 10. Note that when taking out the round bar, the support web 10 must be pressed downward. This allows the round bar to be taken out laterally beyond the spring arm 7.

This support web 10 forms an angle α with the base plate 1, the value of this angle being between 10° and 30°, so that the pushed-in round bar 17 is also placed taut against the base plate 1. It will be destroyed. When pushing the round bar 17,
In order to facilitate bending of the support web 10, this support web 10 can be attached to the inner wall of the second arch 5 with a weakened cross-section by the groove 13.

The distance between the protruding step 11 and the tip 12 of the support web 10 is dimensioned as follows: in the case of a round bar with the smallest diameter, the distance between the round bar 17
After pushing in, the protruding step portion 11 is inserted into the supporting web 10.
It is made to come in close contact with the tip 12 of the.

When inserting a round rod 17 with a larger diameter, the elasticity of the holding fingers 8 ensures that: That is, the holding fingers 8 are connected to the protruding step portions 11.
is pressed in the direction of the rigid first arcuate section 4 until it comes into close contact with the tip 12 of the support web 10.

In the embodiment shown in FIGS. 3 to 7, the support web 10 is rigidly connected to the second arch 5 and to the spring arm 7, forming with them a stable triangle. This support web 10 is in this case mounted directly above the bottom plate 1 and
Parts 5-7-10 that make up this stable triangle
can vibrate both outward and inward at the remaining wall portion 5b of the second arcuate portion 5 due to the pressure of the round bar 17 pushed in.

As is clear from FIGS. 5 to 7, the second arc 5 and the spring arm 7 are only able to bend laterally to a small extent by the support web 10. Therefore, when the round bar 17 is pushed in, the first arcuate portion 4, which is rigid and difficult to bend, must also move laterally in the direction of the arrow "P" and escape in order to widen the introduction passage 9.

Although some force is required to push the round rod in this case, a retaining clip of this construction is easier to manufacture than the retaining clip shown in FIGS. 1 and 2, and is therefore more compact. It can be manufactured cheaply.

Since the holding clip of the present invention has the above-described structure, the round bar 17 is held stably without rolling within the storage chamber, and the round bar does not wobble or shake, and furthermore, the round bar is prevented from rolling. This and the increased holding force in the direction of the second arcuate portion combine to effectively prevent the round bar from flying out of the accommodation chamber due to tension or other external effects.
