Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shift knob with a built-in switch, which is attached to the upper end of a select lever of an automatic transmission, for example, and has a built-in switch for overdrive control, etc.

This type of shift knob with a built-in switch has a recess for storing the switch inside the shift knob, and the opening of the recess for storing the switch is closed with a lid after the switch is installed.If the switch malfunctions, the lid can be opened and replaced. I'm trying to make it possible.

SUMMARY OF THE INVENTION An object of the present invention is to provide a shift knob with a built-in switch in which the lid that closes the opening of the storage recess can be made as small as possible, thereby improving the design.

An embodiment of the present invention will be described below with reference to the drawings. 1 is the select lever of the automatic transmission, 2 is the shift knob fitted on the upper end of this select lever 1, and screw 3
It is bound by. Reference numeral 4 designates a push button that is horizontally movable at the upper end of the shift knob 2. This push button is pressed to unlock the select lever 1 when the select lever 1 is operated to select between specific positions, and is a conventionally well-known push button. There is nothing particularly different from that.

In the following, the shift knob 2 will be described in detail. Reference numeral 5 denotes an inner shell made of hard plastic, and a metal cylindrical body 7 is insert-molded on the inner circumference of a fitting hole 6 into which the select lever 1 is fitted. There is.
Reference numeral 8 denotes a storage recess formed in the inner shell body 5 adjacent to the fitting hole 6, and this is open on the side opposite to the driver when the shift knob 2 is attached to the select lever 1. A rectangular push button insertion hole 9 is formed at the bottom of the storage recess 8 and opens toward the driver. Reference numerals 10 and 10 denote bosses for attaching a switch that protrude in a cylindrical shape from the bottom surface of the storage recess 8, and reference numerals 11 and 11 designate bosses 12 that protrude from the upper edge of the storage recess 8 and the lower inner surface of the storage recess 8. These are fitting holes formed respectively. Reference numerals 13 and 14 are stepped portions formed at the upper and lower opening ends of the storage recess 8, and peripheral wall portions 13a and 14a connected to these stepped portions 13 and 14 are engaged as engaging portions that protrude inward. Convex portions 15 and 16 are provided projecting from the step portions 13 and 14 at a predetermined distance. The storage recess 8 is formed by cutting out the mold in the direction of arrow A, which is the opening direction of the inner shell 5 when molding the inner shell 5 (see FIG. 4). protrudes inward from the peripheral walls 13a and 14a, and therefore undercuts 17 and 18 are formed between the engaging convex portions 15 and 16 and the step portions 13 and 14, and these undercuts 17 and 18
A mold for molding the storage recess 8 through the notches 19 and 20 formed in the side wall of the storage recess 8.
The mold is cut in the direction of arrow B, which is perpendicular to the direction of the mold for molding the mold. The inner shell 5 formed as described above is housed in another mold, and the outer shell 21 is integrally formed around the outer periphery of a soft plastic such as vinyl chloride. This outer shell body 21 has an opening 22 that communicates with the open end of the storage recess 8 and is formed so as to be substantially flush with the peripheral wall of the storage recess 8. Therefore, the notches 19 and 20 are It exhibits a state where it is buried within the outer shell body 21. On the other hand, 23 is a push button switch for overdrive control, for example, which is housed in the storage recess 8 and fixed to the bosses 10, 10 with screws 24, and whose push button 23a protrudes from the push button insertion hole 9 toward the driver. will be established.

Thus, 25 is a lid that is fitted into the opening 22,
This is made by integrally molding an outer skin 27 made of soft plastic onto the outer surface of a lid main body 26 made of hard plastic. Part 2
Shaft portions 28, 28 for positioning when fitting into 2
Claw portions 29 and 29 as engaged portions that are engaged with the engagement convex portions 15 and 16 are integrally molded, respectively. A protrusion 29 made of hard plastic and protruding from the lid main body 26 is exposed on the inner surface of the lid 25, and when the lid 25 is fitted into the opening 22, the protrusion 30 extends through the opening. Since the lid 2 is positioned near the lid 22 and comes into contact with the stepped portion 31 formed on the inner shell 5 made of hard plastic, the lid 2
Even if 5 is pressed from the outside, there will be no inconvenience such as sinking inward.

According to the above configuration, the outer shell 21 has the notch 19,
20, the opening 22 has the necessary minimum size so as to be flush with the opening end of the storage recess 8, and the lid 25 is on the side opposite to the driver, which improves the design. It will be excellent.

Conventionally, in order to form the undercuts 17 and 18, both the inner shell body 5 and the outer shell body 21 are flush with the stepped portions 13 and 14, as shown by two-dot chain lines in FIGS. It had a notch, and the lid was large enough to cover the notch.
Therefore, the shift knob has a joint between the outer shell and the lid that extends not only to the side facing away from the driver but also to the side, making it visible to the driver or the person sitting in the passenger seat. However, with the above structure, as explained above, the lid can be made as small as possible and there is no seam on the side of the shift knob, so the design is greatly improved.

As is clear from the above description, the present invention is aimed at cutting out a mold for forming an engaging portion provided in an inner shell in a direction perpendicular to the opening direction of the storage recess. Since the notch formed at the periphery of the opening is covered by the outer shell,
The opening formed in the outer shell is made as small as possible, and the lid that fits into the opening and closes the open end of the storage recess can be made as small as possible, thereby improving the design. We can provide a shift knob with a built-in switch.
