Abstract

PROBLEM TO BE SOLVED: To increase a limit face with which a click body contacts and reduce wear-out of a click face or the like by punching small grooves at the rough center of a face forming a click groove. SOLUTION: A swing switch is provided with a knob 2 swinging when an axle is centered, a click groove 2g, and a limit mechanism made of a click body 8 pressure-contacted with the groove, and a spring 9 for energizing the body. A small groove 2j is punched at the rough center of two click faces c and d of the click groove 2g made of a V-letter shaped valley extending in a direction in which an axle hole 2e exists, whereby the click faces c and d are halved, and a part at which the click body 8 is pressure-contacted is multiplied. The small groove 2j may be formed on the entire click faces c and d. Preferably, the knob is formed with an outer hull body 2b made of non-crystal resin and an inner hull body 2c made of light conductor such as poly-amide or the like, and the inner hull body 2c is integrally formed from an illumination display port 2d, the click groove 2g, and an operation lever 2h. Thereby, the light of a light emitter is led to the display port 2d, and knob illumination becomes clear and sharp.

There is a problem that it is easily worn.

An object of the present invention is to reduce wear of the moderation surface and the like by increasing the moderation surface with which the moderation body contacts.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the prior art. It is a knob swinging about an axis, a moderation groove, and a pressure contact with the moderation groove. In a rocking switch provided with a moderation mechanism including a moderation body and a spring for urging the moderation body, the moderation groove is formed by engraving a small groove substantially in the center of the surface forming the groove.

According to a second aspect of the present invention, the knob is formed of an outer shell made of an opaque resin and an inner shell made of a light guide, and the inner shell is an illumination display section. And the operating rod and the operating rod are integrally formed.

According to the third aspect of the present invention, the inner shell is made of polyamide.

Since the knobs 3, 4, 5 and 6 have the same structure as the knob 2 described above, the description thereof will be omitted.

The push button 7 has a leaf spring 1 on the side surface of the operating rod 7a.
9 is a push rod switch operation member formed by forming a heart cam (not shown) with which the pin 20 of 9 is pressed. When the push button 7 is pressed, the pin 20 is locked to the heart cam, and the operating rod 7a operates the switch unit 21 to lock / unlock the door. The switch unit 21 may be a tact switch, a rubber contact switch, or the like.

The moderation body 8 includes a steel ball, a moderation pin,
Alternatively, it is a roller or the like and is not particularly limited as long as the tip is circular or spherical. As to the size of the moderation body 8, as shown in FIG. 5, the moderation body 8a has a size such that it is pressed against the slope of the small groove 2j with respect to the small groove 2j opened in a substantially V shape. A moderation body 8 adapted to come into pressure contact with the opening end of the small groove 2j.
Either b or both may be used.

The springs 9 and 10 are moderation springs inserted into blind holes 12b formed in the cylindrical portion 12a. The light emitter 11 is an incandescent light bulb, a light emitting diode, or the like.
The case 12 has the knobs 2, 3, 4, 5, 6 and the push button 7 arranged on the upper surface, and the lower case 22 arranged on the lower surface via the substrate 18 and the switch units 13, 14, 15, 16, 21. I have set up. The case 12 has a locking hole 1 formed on the side surface.
The board 18 is sandwiched between the lower case 22 and the lower case 22 by engaging the claws 22a of the lower case 22 with 2c. The case 12 is
Screwed to the driver's door of the car. Locking hole 12c
An enclosure 12d for preventing intrusion of raindrops falling from above is provided around the area.

Each switch unit 13, 14, 15, 1
6, 17 and 21 are small slide switches or the like having an operating rod 13a that slides. The switch units 13, 14, 15, 16 and 21 have lead terminals inserted into the through holes of the substrate 18 and soldered, and the lower surfaces thereof are supported by the lower case 22. The switch unit 1
3, 14, 15, 16, 21 are knobs 2, 3, 4, 5,
It suffices that the switch actuates when the buttons 6 and 6 are operated, for example, a switch contact piece or a small switch.
The board 18 is provided with the operating rods 2 for the knobs 2, 3, 4, 5 and 6.
Notches 18a through which h is inserted, insertion holes 18b, and through holes are formed. The leaf spring 19 and the pin 20 are arranged on the tubular portion 12 a of the case 12.

The present invention has the above-mentioned structure, and the operation will be described in detail with reference to FIGS. 1 to 3. Knobs 2, 3,
When the switches 4, 5 and 6 are OFF, the moderator body 8 is
It is biased by the spring 9 and is in pressure contact with the approximate center of the V-shaped moderation groove 2g. The moderation body 8 presses the four moderation surfaces c and d of the moderation groove 2g by engraving a small groove 2j at approximately the center of the moderation surfaces c and d forming the moderation groove 2g. Since the force with which the moderation body 8 is pressed into contact with the moderation groove 2g is distributed into four, it is possible to prevent the moderation groove 2g and the moderation body 8 from being worn and deformed, and to improve the durability.

When the knob 2 is pulled up in the direction of the arrow A, the knob 2 rotates in the direction of the arrow A around the shaft hole 2e, and the moderating body 8 is pressed against the moderation surface c of the moderation groove 2g. Since the small groove 2j is formed substantially in the center of the moderation surface c of the moderation groove 2g, the moderation body 8 is formed on the two sides of the moderation surface c on both sides of the moderation groove 2j.
Press on the place.

When the knob 2 is pressed in the direction of arrow B, the knob 2 rotates in the direction of arrow B around the shaft hole 2e,
The moderation body 8 is pressed against the moderation surface d of the moderation groove 2g. Since the small groove 2j is formed substantially in the center of the moderation surface d of the moderation groove 2g, the moderation body 8 is pressed against two positions of the moderation surface d on both sides of the small groove 2j.

When the knob 2 is operated in the directions of arrows A and B,
Since the moderation body 8 is pressed into contact with two moderation surfaces c and d of the moderation groove 2g, the force of pressure contact with the moderation groove 2g is dispersed into two. Thereby, the moderation groove 2g and the moderation body 8 are prevented from being worn and deformed, and the durability can be improved.

Further, the knobs 2, 3, 4, 5 and 6 are integrally formed with the moderation groove 2g and the operating rod 2h by the inner shell 2c of polyacetal which is the same light guide as the illumination display portion 2d. It is hard to improve the wear resistance, and guides the light from the light emitting body 11 to the illumination display section 2d for clear knob illumination.

When the knob 2 is pulled up in the direction of the arrow A, the knob 2 rotates in the direction of the arrow A around the shaft hole 2e, and the operating rod 2h actuates the switch unit 13 to open the window of the driver's seat. The glass rises. When the knob 2 is pressed in the direction of arrow B, the knob 2 rotates in the direction of arrow B around the shaft hole 2e, and the operating rod 2h actuates the switch unit 13 so that the window glass of the driver's seat is opened. To descend.

When the knob 3 is oscillated, the window glass in the passenger seat is raised or lowered. When the knob 4 is rocked,
The window glass on the left side of the rear seat moves up and down. When the knob 5 is rocked, the window glass on the right side of the rear seat moves up and down. When the knob 6 is swung, the window glass other than the driver's seat is locked / unlocked.
