Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a knob mounting structure for a shift operation lever of a vehicle transmission.

[0002]

[Prior Art]

 As a knob mounting structure for a gear shift operation lever of a vehicle transmission, for example, as disclosed in Japanese Utility Model Laid-Open No. 63-43540, a compression body is inserted into an operation lever at an upper end portion of the knob body and protrudes upward. A push-button fitting hole is formed to push the rod to disengage the position pin from the position plate.The knob body is inserted through the upper end of the operating lever, and the lower end of the knob is inserted into the operating lever. It fits into the escutcheon positioned at the upper end, and a nut is screwed and fastened to the threaded part at the upper end of the operating lever that protrudes from the hole bottom part of the fitting hole. It is known that it is fixed to the upper end.

[0003]

[Problems to be solved by the device]

 The push button is placed in the fitting hole after tightening the nut to the upper end of the operating lever of the knob body, so when the knob body needs to be removed, this push button removal work is accompanied by workability. It gets worse.

Further, since the push button cannot be sub-assembled to the knob body, there is a disadvantage that the man-hours for managing parts and the man-hours for working on the vehicle body assembly line increase. Further, since the nut is tightened in the fitting hole at the upper end of the knob body, the fitting hole needs to secure a tool space for the nut tightening work, which restricts the degree of freedom in shaping the knob body. There is also a disadvantage. The same thing can be said for the operating lever for a manual transmission in which the fitting hole at the end of the knob body is closed with an ornament without attaching a push button.

Therefore, the present invention provides a knob mounting structure for a gear shift operation lever, which is easy to mount and dismount, and which can increase the degree of freedom in shaping the knob body.

[0006]

[Means for Solving the Problems]

 In the structure in which the knob body and the escutcheon connected to the lower end portion of the knob body are inserted and attached to the upper end portion of the operation lever, the sliding contact portions of the operation lever and the knob body are engaged with each other. A step portion for positioning that regulates the downward movement of the knob body is formed, and at the same time, a slip-out prevention mechanism that engages with each other and regulates the upward movement of the escutcheon is provided at the sliding contact portion between the operation lever and the escutcheon. On the other hand, female and male screw parts are formed on the knob body and the escutcheon, and these female and male screw parts are screwed together to fasten and fix the knob body and the escutcheon.

[0007]

[Action]

 By screwing the knob body and the female and male threads of the escutcheon, the knob body is pressed against the operation lever at the step, while the escutcheon is pressed against the operation lever at the retaining mechanism, , The escutcheons are securely fixed to the operating lever.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes an operation lever, through which a compression rod 2 having a position pin (not shown) projectingly engaged with a groove of a position plate at a lower end thereof is inserted. is there. A pair of flat surfaces 3 are formed opposite to each other on the upper end portion of the operation lever 1 to form a non-circular shape, and a step portion 4 is formed on the molding base portion thereof.

Reference numeral 5 denotes a knob body which is inserted and arranged in the upper end portion of the operation lever 1, and a non-circular engagement hole which engages with a non-circular portion of the operation lever 1 in which a flat surface 3 is formed in a central portion thereof. 6 is formed so as to be inserted into the operation lever 1 in a non-rotatable manner, and a step portion 7 is formed at the lower edge of the engaging hole 6 so that the step portion 4 is engaged with the step portion 4 to move downward. The movement is regulated and the location is set. An upper portion of the engagement hole 6 of the knob body 5 is provided as a disposition hole 8 for the push button 9. The disposition hole 8 is provided with a push button 9 which is prevented from being pulled out by a button guide 10. By pushing the button 9, the compression rod 2 projecting from the upper end of the operation lever 1 is pushed downward to release the engagement of the position pin with the position plate (not shown). Further, a female screw portion 11 for connecting an escutcheon 12 described later is formed in a lower portion of the engagement hole 6 of the knob body 5.

Reference numeral 12 denotes an escutcheon which is inserted into an upper end portion of the operation lever 1 and is connected to a lower end portion of the knob body 5. The escutcheon 12 is restricted from upward movement with respect to the operation lever 1 by a retaining mechanism 14. ing.

In the present embodiment, the retaining mechanism 14 is formed in a ring 16 fitted in a groove 15 formed on the outer periphery of the operation lever 1 and a lower portion of a lever insertion hole of the escutcheon 12 to engage with the ring 16. It is configured with the step portion 17 which is matched. Further, a male screw portion 13 that is screwed into the female screw portion 11 of the knob body 5 is formed on the outer periphery of the upper portion of the escutcheon 12, and by screwing the female and male screw portions 11 and 13, the knob body 5 and the escalator are screwed. The operation lever 12 is fastened and fixed to the operation lever 1.

According to the structure of the above embodiment, the escutcheon 12 is inserted into the upper end portion of the operation lever 1 and the ring 16 is fitted into the groove 15 of the operation lever 1 to prevent the escutcheon 12 from being pulled out upward. After that, the knob body 5 sub-assembled with the push button 9 is similarly inserted into the upper end portion of the operation lever 1 and the non-circular end portion is engaged with the engaging hole 6 to engage the step portions 4 and 7 with each other. Then, the knob body 5 is positioned. Then, the end of the male screw portion 13 of the escutcheon 12 is inserted into the female screw portion 11 of the knob body 5, and the escutcheon 12 is rotated to screw the female and male screw portions 11 and 13 into each other. The step portion 7 is pressed against the step portion 4 of the operation lever 1, while the step portion 17 of the escutcheon 12 is pressed against the ring 16 of the operation lever 1, so that the knob body 5 and the escutcheon 12 are attached to the operation lever 1. It can be securely clamped and fixed. This fastening work can be performed easily by rotating the escutcheon 12 outside.

On the other hand, when it is necessary to remove the knob body 5 for replacement, maintenance, inspection, etc. of the operation lever 1, the compression rod 2, the knob body 5, etc., if the above-mentioned assembly procedure is reversed, In other words, if the escutcheon 12 is rotated to disengage the male screw portion 13 from the female screw portion 11, the knob body 5 can be easily detached from the operation lever 1, and the push button 9 is not detached. In this case, the work can be done easily.

Further, unlike the conventional knob structure in which the knob body 5 is fixed to the upper end of the operation lever by tightening the nut, it is not necessary to secure a tool space inside the knob body 5, so that the degree of freedom in shaping the knob body 5 is high. Since the push button 9 can be sub-assembled to the knob main body 5, the man-hours required for parts management on the vehicle body assembly line can be reduced.

The retaining mechanism 14 described above is not limited to the above-described embodiment, and may have a hook structure, and the present invention is an operation for a manual transmission that does not have the compression rod 2 and the push button 9. The same applies to the lever.

[0017]

[Effect of the device]

 As described above, according to the present invention, the knob body can be easily assembled and removed from the outside by screwing or loosening the knob body and the female and male screw portions of the escutcheon. In this case, there is no need to remove pushbuttons or ornaments attached to the top of the knob body, so work can be significantly improved, and there is no need to secure a tool space inside the knob body. The degree of freedom in shaping the knob body can be increased.
