Description

[Detailed Description of the Invention] This invention relates to a switch mechanism that allows a rubber contact switch to be switched in multiple directions by tilting the handle shaft back and forth, left and right, etc.

The above-mentioned switch mechanism was applied to TV game machines and LCD game machines, but in the case of these devices, it is necessary to perform tilting operations of the handle shaft extremely quickly and frequently, and when the switch mechanism is operated, force is applied and the rubber contact Problems arose when twisting the switch or pushing it too hard would shorten its lifespan.

This idea was developed to solve the above problem.The rubber contact switches arranged in multiple directions are actuated by tilting the disk, and even when tilting operations are performed quickly and frequently, the rubber contact switches do not have to be twisted. The purpose is to provide a switch mechanism that does not require pressing too hard.

Next, this invention will be explained based on an embodiment shown in the accompanying drawings.

Reference numeral 1 denotes a substrate on which a certain electric circuit (not shown) is attached and a cover plate 1' is stacked on top, 2 a top plate placed above the substrate 1 at a fixed interval, and 3 the cover plate. It is a disk body supported so as to be tiltable in front, back, left and right (universal shape) between a substrate 1 and a top plate 2, which are stacked with 1′, and a hemispherical raised portion 4 is provided at the center of the upper surface of the disk body 3. A handle shaft 5 integrally projects from the top of the raised portion 4. The handle shaft 5 is
It protrudes to the outside through a large-diameter hole 6 provided in the top plate 2, and a cap 7 is mounted on the protruding end and fixed with screws 8.

As a means for tiltably supporting the disk body 3 between the substrate 1 and the top plate 2, in the case shown in the figure, a circular hole 9 is provided at the center of the lower surface of the disk body 3, and a hole is formed on the inner end surface of the circular hole 9. A vertical hole 10 was bored along the axis of the handle shaft 5, and a protruding rod 12 that could be protruded by the elastic force of a spring 11 was provided in the vertical hole 10, with the lower end of the protruding rod 12 protruding from the upper surface of the substrate 1. When making contact with the base 13, spherical concave holes 14, 14' are provided in the abutting surfaces of the protrusion 12 and the base 13, and a spherical body 15 is interposed between the spherical concave holes 14, 14', while the disk The upper surface of the body 3 is received by an annular projection 16 hanging down from the lower surface of the top plate 2 so as to surround a large diameter hole 6.
By doing this, the disc body 3 is in the position of the prong 1 in normal times.
The handle shaft 5 is pushed upward by the elastic force of the spring 11 that presses the top plate 2, and is stably held horizontally by the annular protrusion 16 of the top plate 2, accurately holding the neutral position, and when tilting the handle shaft 5.
The contact surface between the protrusion 12 and the base 13 with the spherical body 15 interposed therebetween slides, allowing smooth tilting. Of course, the same result as described above can also be obtained by making the lower end of the protruding rod 12 into an inverted conical shape, and by making the upper surface of the pedestal 13 into an inverted conical shape with a gentler angle than that, and bringing the two into contact. be. Reference numeral 17 denotes an annular projection projected downward from the circumference of the circular hole 9 on the lower surface of the disc body 3, and the annular projection 17 has the spherical body 15 interposed between the protruding rod 12 and the pedestal 13 as described above. In this case, the spherical body 15 is prevented from jumping out. Reference numeral 18 denotes a notch groove extending from the outer periphery toward the center of the disk body 3, and the notch groove 18 fits into a guide frame 19 hanging down from the lower surface of the top plate 2 while maintaining a necessary clearance. The notch groove 18
The guide frame 19 is for preventing the disk body 3 from rotating in the circumferential direction when it is tilted.
Reference numeral 20 denotes four rubber contact switches installed equidistantly on the substrate 1 corresponding to the lower surface of the outer periphery of the disk body 3. It is set to protrude. This cover plate 1' serves as a holding plate for each of the rubber contact switches 20, and also functions as a stopper for regulating the maximum tilt angle of the disc body 3, so as to prevent the rubber contact switches 20 from being pressed more than necessary. In addition, the guide frame 1
The hanging position 9 is a neutral point (minimum tilting point) with respect to the tilting movement of the disk body 3 in the front, back, left, and right directions, that is, the midpoint of the two adjacent rubber contact switches 20, 20. Therefore, when the handle shaft 5 is tilted back and forth and left and right, the groove width of the notch groove 18 can be determined to be the minimum width within the range where the gail frame 19 does not become an obstacle, and the handle shaft may be tilted if the groove width becomes too wide. There is no danger that 5 will be twisted more than necessary.
21 is an inclined surface provided on the lower surface of the outer periphery of the disc body 3;
2 is a marking line on the upper surface of the top plate 2 indicating the direction in which the rubber contact switch is provided, that is, the direction in which the handle shaft 5 is tilted.

Since this device is constructed as described above, the disk body is supported between the top plate and the base plate with the cover plate stacked on top, and is tiltable by operating the handle shaft protruding from the center of the top surface. Since the rubber contact switch is closed by closing the rubber contact switch, the contact with the rubber contact switch is soft, and the notch groove provided on the outer periphery of the disc body fits loosely into the guide frame hanging down on the bottom surface of the top plate. Since it does not rotate in the circumferential direction during tilting, not only will the rubber contact switch not be twisted even by rough operation, but the disc body can be adjusted to its maximum tilting angle by a cover plate stacked on the top of the board. is regulated, so there is no need to press the rubber contact switch more than necessary. Therefore, even when switching in multiple directions is quickly and frequently repeated as in an electronic game machine, the rubber contact switch is extremely unlikely to be damaged.
