Description

[Detailed Description of the Invention] Conventional regulator handles for vehicles have generally been made by inserting the shaft of a synthetic resin knob into a hole in a metal handle body and caulking the handle.

However, although this was sufficiently satisfactory in terms of strength, it had the disadvantage of being heavy.

Therefore, in order to reduce the weight, a regulator handle in which the handle body 1 is made of resin as shown in FIG. 1 has been proposed.

However, unlike metal knobs, resin knobs cannot be connected by caulking, so a slit 4 is formed in the shaft portion 3 of the knob 2, and a clip 5 is provided on the remaining shaft portion excluding the slit 4. The clips 5, 5, . . . were inserted into a hole 6 of a cylindrical body 1' formed in the handle body 1 with a shortened distance between them, and were attached to the knob 2 so as to be rotatable.

In this case, the inner circumferential protrusion 7 provided at the end of the hole 6 of the cylindrical body 1' of the handle body 1 and the stepped portion 8' of the groove 8 formed on the outer circumferential surface of the clip 5 engage with each other. In this state, the knob 2 is in the connected state shown in FIG. 3, and the knob 2 is rotatable, but the shaft 3 of the knob 2 is not pulled out from the hole 6 of the handle body 1.

By the way, as shown in FIG. 5A, in the conventional regulator handle knob, the outer diameter of the shaft portion 3 of the knob 2, that is, the outer diameter of the clips 5, 5, etc., is the center of the shaft portion 3. It was formed into a circle with 9 in the center.

Therefore, the center of the circular arc passing through the sector-shaped outer circumferential portion 10 of the clip 5, that is, the center 9 of the shaft portion 3 and the sector-shaped center 11 do not coincide.

Therefore, when the width of the slit 4 is shortened as shown in the opening in FIG. center of 9
Although the centers 11 of the fan shapes almost coincide with each other, the circumference formed by the outer circumference 10 of the four clips 5 does not have a circular shape similar to the hole 6 of the handle body 1, and as shown in FIG. The shape is almost square, like a mouth.

Then, in response to the tensile force in the direction of the arrow A, the four square corners 12 are caught on the inner circumferential protrusion 7 of the hole 6 as shown in FIG.
The knob 2 will not come out from the hole in the handle body 1, but if the pulling force in the direction of arrow A becomes large and the temperature becomes particularly high, the knob 2 will not come out if only the four corners 12 are caught.
The problem was that it could be pulled out through the hole.

The present invention was proposed in order to solve the above-mentioned conventional drawbacks, and the outer circumference of the clip formed on the shaft of the knob is not a circumference centered on the center of the shaft, but a fan-shaped center of each clip. It is an object of the present invention to provide a regulator handle for a vehicle in which the knob is not easily removed from a hole in the handle body by having a circumference centered at .

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 6 and 7 show an embodiment of the present invention. Reference numeral 1 denotes a handle body made of resin as in the conventional case, and a cylindrical body 1 provided on the body 1. An inner circumferential protrusion 7 is formed at the end of the hole 6 of '.
Four clips 15 formed by slits 19 radially provided at the tip of the shaft portion 14 provided on the resin knob 13 are inserted through the inner circumferential protruding edge 7 at closer intervals. ing.

The outer circumference 16 of each clip 15 constitutes a part of the circumference centered on the sector-shaped center 17 forming each clip,
When the clips 15 are brought into contact with each other, each circumference constitutes one circle, and this circle is formed to be approximately the same as or slightly smaller than the hole diameter of the inner circumferential flange 7.

Further, a groove 18 is formed on the outer periphery of the clip 15 to engage with the inner peripheral protrusion 7.

Therefore, if the width of the slit 19 is shortened and the distance between the clips 15 becomes closer, the state shown in FIG. 7 will be obtained. When the knob 13 is engaged, the knob 13 can be rotated.
The knob 13 is attached to the handle body 1 by the stepped portion 18' of the groove 18.
There will be no karanuki.

In this locked state, the knob 13 is moved in the direction of arrow A in Fig. 7 (Fig. 7 shows the inserted state and does not show the removed state, but arrow A is shown for convenience). When a tensile force is applied, the intervals between the clips 15 are reduced, and the centers 17 of each sector are brought together in one place, as shown in the opening of FIG.

However, even if the tensile force in the direction of arrow A becomes considerably large,
Due to this tensile force, each clip 15 does not come into contact so that each slit 19 is completely eliminated.

That is, since each clip 15 does not come into a state of complete contact due to the elastic force of the clip 15, each clip 15
The outer periphery 16 becomes almost circular, but this circular shape is larger than the inner peripheral flange 7 as shown in the opening in Figure 6, and the entire circumference is hooked on the inner peripheral flange 7. The resistance to removal is much greater than when a part of it is caught on the inner circumferential protrusion 7 as in the case of a drawing opening.

In addition, although the example of FIG. 6 demonstrated the case where four clips 15 were provided, this is not limited to four, and may be three.

As explained above, in the present invention, the outer periphery of the clip formed on the shaft of the knob is formed with a circumference centered on the center of the fan shape of each clip. The resistance when pulling out from the inner periphery of the hole in the handle body is much greater than when the handle body has a square shape, so even if the temperature is high, the knob can be pulled out easily from the handle body. Never.
