Description

[Detailed Description of the Invention] Recently, with the diversification of people's tastes, a wide variety of parts are being provided in the field of car accessories. Among these parts, the present invention relates to improvements in change knobs for vehicles, primarily automobiles.

Conventionally, this type of change knob is attached by screwing a synthetic resin central shaft inserted into the knob body into a threaded shaft portion carved into the tip of the change lever. However, the dimensions of the screw shaft vary depending on the year, model, and company of the car (generally 8m/
There are said to be three types: m, 10m/m, and 12m/m. ), the center shaft must be changed according to its dimensions for manufacturing, stocking, and display, which is undesirable in the current situation where accessory parts are diversifying and becoming more diverse. In particular, manufacturing several types of change knobs with the same shape according to different dimensions is problematic in terms of work, cost, increase in inventory, and complication of transactions.

SUMMARY OF THE INVENTION The object of the present invention is to provide a change knob that can be screwed onto and removed from change levers of various sizes by simply assembling compatible parts to the change knob, thereby solving the above-mentioned conventional problems.

Embodiments of the present invention will be described based on the drawings.

Reference numeral 1 denotes a knob body having a cavity 2 that opens toward the bottom surface 1a, and this cavity 2 has a screw 3 on its inner peripheral surface.
A fixed bush 4 having a shape is fitted therein, and the inner surface of the flange 4a is in contact with the bottom surface 1a. A fixing bush 4 is integrally inserted into a so-called knob body 1. The bottom wall 4b of the fixed bush 4 is provided with a through hole 5 into which a threaded shaft portion of a change lever to be described later is inserted. 6 is a screw 8 that engages with the screw 3 on the outer peripheral surface.
is a cylindrical insertion bush having a screw 9 which is a reverse thread to the screw 8 carved on the inner circumferential surface, and is screwed onto and removed from the fixed bush 4. and fixed button 4
When the fixed bushing 4 is screwed into the bushing, a small space A is formed between the bottom of the fixed bushing 4 and the top surface of the insertion bushing, and an elastic body 10 such as a rubber, a spring, a washer, etc. is inserted into this space A. There is. The change knob configured in this way is attached to the screw shaft 1 of the change lever 12.
3 and install it. In this case, the vibrations of the automobile may propagate to the occlusal surface of each screw, causing the occlusal surface (especially when the occlusal surface is slightly stiff) to loosen, so the elastic body 10 is used to loosen the occlusal surface. Make it stronger. That is, since the insert bush 6 is constantly pressed downward in FIG. 1 by the resilient body 10, the engagement between the screw 9 and the screw 13a of the helical shaft portion 13 becomes particularly strong, and the change knob is unscrewed. There is little risk. In the figure, reference numeral 11 denotes a notch groove provided on the lower surface of the insertion bush 6 for screwing.

As explained in detail above, the present invention consists of a fixed bush fitted into the knob body, and an insert bush with an appropriate wall thickness corresponding to the dimensions of the helical shaft of the change lever (for example, when the diameter is 8 m/m, the insert bush with the maximum wall thickness is attached). Since the structure is such that the bushings can be freely rearranged and screwed on, if you simply manufacture and stock several types of plug-in bushings, the knob body can have the same dimensions, and you can use change knobs of the same shape to match each dimension, as in the past. There is no need for manufacturing. Therefore, it is possible to improve the efficiency of manufacturing work, and it is also economical. In particular, if the knob body and fixed bushings of the same shape are prepared, only a few types of plug-in bushings are required, which reduces inventory. This has the effect of reducing the amount of display space and making it easier to handle parts. Furthermore, since the projecting body is interposed as described above, there is less risk of the change knob becoming unscrewed due to the vibrations of the automobile, and the repulsive force of the projecting body strengthens the engagement between the screws 9 and 13a. By stopping the change knob at the front position, it can be properly fixed at that position.
