Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a clip that connects an operating rod linked to an inside handle or an outside handle to a connecting plate for actuation, for example in an automobile door lock mechanism. It is.

``Prior art'' As a conventional connection clip of this type, the
There is one shown in Publication No. 57-48308.

The conventional clip is an integrally molded product made of synthetic resin, and includes a cylindrical body into which the bent end of the rod is fitted;
It consists of a flange formed on the upper outer periphery of the cylindrical body, and a gripping body connected to the flange via a hinge to grip the linear body of the rod, and the cylindrical body has a locking step on the entire lower periphery. In addition, a plurality of inverted V-shaped slits are formed at a portion extending from the lower end to a position slightly above the locking stepped portion to allow the diameter of the cylinder itself to be reduced.

When using the clip to connect the bent end of the rod linked to the inside handle or the like to the operating connecting plate of the door lock mechanism, first insert the clip through the locking step and the flange. After fitting the cylindrical body into the hole drilled in the connecting plate, the bent end of the rod is inserted into the cylindrical body, and at the same time, the straight main body of the rod is gripped by the gripping body, thereby removing the rod. is connected to the connecting plate.

``Problems to be Solved by the Invention'' However, in such conventional connecting clips, the inside of the cylindrical body has an equal inner diameter that allows the bent end of the rod to be tightly fitted, and the connecting plate is formed over the entire outer periphery. Since the structure forms a locking step that locks on the edge of the hole, it is difficult to lock the cylinder into the hole of the connecting plate while the bent end of the rod is already inserted into the cylinder of the clip. It is.

For this reason, in the case of conventional clips, the diameter of the cylindrical body is first reduced through the slit as described above, and after the cylindrical body is engaged with the hole in the connecting plate, the rod is folded into the cylindrical body. Since the curved end portion has to be fitted, the fastening work and the fitting work are required to be carried out independently, respectively, resulting in a problem that the work becomes unnecessarily complicated.

Furthermore, the presence of a plurality of slits that allow the diameter of the cylindrical body to be reduced has the disadvantage that it is inferior in waterproof and dustproof properties.

In addition, as a conventional technology, there are also
There is also a clip shown in Publication No. 80711, but this clip, like the conventional clip described above, adopts a structure in which the diameter of the cylindrical body is reduced through a slit formed in the side wall of the cylindrical body. In relation, as expected,
It cannot be denied that each of the above problems exists.

``Means for Solving the Problems'' Therefore, the present invention was developed to effectively solve the problems of the conventional connecting clips mentioned above. A cylindrical body that
A resin connection that connects the rod to the connection plate by locking the cylinder into a hole in the connection plate. The cylindrical body is formed into a bottomed shape with an opening only on the top side, and the opposing inner wall surface of the cylindrical body has a diameter larger than the general inner diameter of the peripheral side wall of the cylindrical body. The wall portion is a thin wall portion continuous from the general peripheral wall portion, and a groove-shaped cavity extending in the vertical direction is formed, and only the outer wall surface of each thin wall portion is provided with a locking member that engages with the hole edge of the connecting plate. A configuration is adopted in which a stop step is formed and the thin wall portion on which the stop step is formed is deformed inward through an inner cavity when force is applied to the stop step.

``Function'' Accordingly, in the present invention, when the cylindrical body of the clip is secured in the hole of the connecting plate, the thin wall portion of the cylindrical body having the locking step portion is made hollow in the process of passing through the hole. The rod is deformed inward through the hole to allow passage through the hole in the locking step, so even if the bent end of the rod is already inserted into the cylinder, the cylinder can be inserted into the hole in the connecting plate. It becomes possible to attach to.

``Example'' Hereinafter, the present invention will be described in detail based on an example illustrating the present invention.The connecting clip according to this example is also an integrally molded product of synthetic resin.
It consists only of a gripper 2 placed horizontally on the upper part of the holder.

Specifically, as shown in FIGS. 1A to 1C, the cylindrical body 1 of this embodiment is formed into a bottomed shape having an opening only on the upper surface side, and on the opposing inner wall surfaces of the cylindrical body 1, Groove-shaped hollow portions 3, 3 that extend in the vertical direction and have a larger diameter than the inner diameter of the general portion of the circumferential wall of the cylinder 1 and form a thin wall portion 1a continuous from the general portion of the circumferential wall.
, and the opposing thin wall portions 1a,
A locking step 4 that locks to the hole edge of the connecting plate is integrally formed only on the outer wall surface of the connecting plate 1a, and each thin wall portion 1a on which this locking step 4 is formed is attached to the locking step 4. It is configured so that it can deform inwardly through the cavity 3 existing inside when force is applied. Further, the cylindrical body 1 is configured such that a semicircular flange portion 5 is integrally formed on the side where the grip body 2 is not installed horizontally.

On the other hand, as shown in the figure, the gripping body 2 is formed into a C-shape that allows the linear main body of the rod to be gripped in a detachable manner from the lateral direction.

Therefore, using a connecting clip with such a configuration,
A connecting plate 7 for operating the door lock mechanism connects the bent end 6a of the rod 6 connected to the inside handle, etc.
When connecting the rod 6 to the cylindrical body 1, as shown in FIG. After this, when the cylinder 1 is pushed into the hole 7a of the connecting plate 7, as shown in FIG. 3A,
During the pushing process, the thin wall portions 1a, 1a of the cylinder 1 having the locking steps 4 are deformed inward due to the presence of the hollow portion 3, allowing the locking steps 4, 4 to pass through the hole 7a. Even if the bent end 6a of the rod 6 is fitted into the cylindrical body 1 in advance, not only can the cylindrical body 1 be easily engaged with the hole 7a of the connecting plate 7, but the cylindrical body With only one fastening operation, it becomes possible to immediately connect the rod 6 to the connecting plate 7, as shown in FIG.

Moreover, unlike conventional clips, the cylindrical body 1 of this clip has a bottomed shape with an opening only on the upper surface side, and no slit for diameter reduction is formed on the side wall side. Combined with the shape,
It also has excellent waterproof and dustproof properties.

``Effects of the Invention'' As described above, the present invention employs the above-mentioned configuration, and unlike the conventional method, even if the bent end of the rod is inserted into the cylindrical body in advance, the cylindrical body can be directly inserted into the hole of the connecting plate. Since it becomes possible to lock the rod inwardly, the work of connecting the rod to the connecting plate is greatly simplified compared to the conventional diameter-reduced type using a slit.

Moreover, the cylindrical body of the clip according to the present invention does not require any diameter reduction slits as in the past.
It can be expected that the connecting portion will be sufficiently waterproof and dustproof.
