Description

[Detailed description of the invention] (Field of industrial application) The present invention is a multi-contact lever switch used in so-called video game machines, etc., to operate a large number of contacts selectively and freely to change the screen. It is related to.

(Prior technology) As a conventional lever switch of this type, the
As described in Publication No. 143635, the shaft portion of the operating lever that is freely supported on the board is guided by a four-way guide hole or an eight-direction guide hole so that the shaft portion of the operating lever is almost mutually moved around the shaft portion of the operating lever. The switch levers of four switches arranged at an angle of 90 degrees are configured to operate individually or two adjacent switch levers simultaneously, and eight-way guide holes are provided in the switch support plate, and four-way guide holes are provided in the switch support plate. A multi-contact lever switch is known in which a guide chip is positioned concentrically with an eight-direction guide hole and is replaceably provided on a switch support plate with a screw or the like.

(Problems to be Solved by the Invention) However, in the conventional multi-contact lever switch as described above, for example, a guide chip having a 4-way guide hole is used to switch from an 8-way guide hole to a 4-way guide hole. When attaching the switch to the switch support plate, it is necessary to remove the switch on the switch support plate, which poses the problem that replacement is not easy.

In view of the above-mentioned problems, the present invention aims to provide a multi-contact lever switch that can extremely easily switch between an 8-way guide hole and a 4-way guide hole.

(Means for Solving the Problems) According to the present invention, as shown in the drawings, the operating lever 2 that is freely supported on the base plate 1 and the four switch levers 7a are operated by the operating lever. Four switches 7 are arranged so as to surround the shaft of the control lever at an angle of approximately 90 degrees to each other, and the shaft portion 2a of the control lever 2 is arranged in eight directions in a plane perpendicular to the axis. In the multi-contact lever switch, the plate 5 provided with the 8-direction guide hole 6 has a circular recess 8 substantially concentric with the 8-direction guide hole 6.
A guide hole switching operation plate 9 is rotatably mounted in the recess 8 , and a linear switching piece guide groove 13 for each of the four circular switching pieces 12 is provided in the recess 8 around the guide hole 6 . are provided at an angle of 90° to each other, and an eccentric pin 14 is protruded from one side of each switching top 12, and an engaging pin 16 is protruded from the other side at a position corresponding to the eccentric pin 14. An arc-shaped eccentric pin guide groove 15 is provided in the switching top guide groove 13, and a hooking hole 17 that engages with the hooking pin 16 is provided in the guide hole switching operation plate 9, and switching is performed by rotating the operation plate 9. It is characterized in that a part of the top 12 protrudes into the eight-direction guide hole 6 to form a four-direction guide hole.

(Function) According to the present invention, the operation plate 9 is rotated as shown by arrow A from the 8-direction guiding position shown in FIG.
When the switching top 12 is moved to the four-direction guide position shown in the figure, the switching top 12 is moved linearly into the linear top guide groove 15, and during this linear movement, the eccentric pin 14 of the switching top 12 is moved by the arc-shaped eccentric pin guide groove 15. The switching top 12 is rotated while being guided, and as a result, a part of the switching top 12 protrudes into the eight-direction guide hole 6 as shown in FIG. 7, thereby forming an approximately cross-shaped four-direction guide hole. Ru.

(Example) An embodiment of the present invention will be described with reference to the drawings.

As shown in the drawing, an operating lever 2 is freely supported on a base plate 1 by its spherical portion 3, a switch mounting plate 5 is fixed on a support plate 4 fixed to the base plate 1, and a substantially circular shape is formed at the center of the switch mounting plate 5. or octagonal 8
A direction guide hole 6 is provided, and the tip shaft portion 2a of the operating lever 2 passes through the guide hole 6. Four switches 7 are mounted on the switch mounting plate 5, and the switch levers 7a are arranged at approximately 90 degrees to each other. They are arranged so as to surround the tip shaft portion 2a of the operating lever 2 at an angle of .

On the side of the support plate 4 of the switch mounting plate 5, there is a third
As shown in the figure, a circular depression 8 approximately concentric with the eight-direction guide hole 6 is provided, and a guide hole switching operation plate 9 shown in FIG. The operation knob 11 of the operation plate 9 is formed to protrude to the outside through the side opening 10 (see FIG. 6).

In the recess 8, linear piece guide grooves 13 for each of the four circular switching pieces 12 (see FIG. 5) are further provided on the bottom surface of the recess 8 at an angle of 90° around the guide hole 6. Each guide groove 13 is further provided with an arc-shaped eccentric pin guide groove 15 at the bottom of the top guide groove 13 for guiding a pin 14 protruding from the switching top 12 at an eccentric position. A hooking pin 1 protruding from the switching piece 12 on the opposite side
6 is a hooking hole 1 provided in the guide hole switching operation plate 9
It is multiplied by 7.

With this configuration, the operation plate 9 can be moved from the 8-direction guidance position shown in FIG. 6 to the 4-direction guidance position shown in FIG.
When the switching top 12 is moved to the direction guide position, the switching top 12 is moved linearly into the linear top guide groove 15, and during this linear movement, the eccentric pin 14 of the switching top 12 is guided by the arc-shaped eccentric pin guide groove 15 for switching. The top 12 is rotated, and as a result, a portion of the switching top 12 protrudes into the eight-way guide hole 6 as shown in FIG. 7, thereby forming a substantially cross-shaped four-way guide hole.

Note that the switching operation plate 9 can be moved to the 4-direction guide position and the 8-direction guide position.
In order to hold it in this position after it has been moved into the directional guidance position, suitable latching means may be provided, for example by means of a concave and convex engagement.

(Effect of the invention) According to the invention, the 8-direction guide hole can be transformed into a substantially cross-shaped 4-direction guide hole simply by manually rotating the guide hole switching operation plate from the 8-direction guide position to the 4-direction guide position. This provides the effect that the guide holes can be switched extremely easily.
