Description

The present invention relates to a rotating mechanism for a handle of a game machine or the like.

[Conventional technology]

2. Description of the Related Art Conventionally, there is known a game machine using a race simulation of a car or the like, which allows a car displayed on a cathode ray tube to be operated by operating a steering wheel so as to enjoy the car. This handle is provided with a stopper on the handle shaft so as not to rotate more than a certain angle, and the rotation is stopped by the stopper when the handle is rotated by a certain angle in either the left or right direction.

[Problems to be Solved by the Invention]

In the above configuration, since the stopper is fixedly installed at a fixed position, the stopper acts when rotated at least half a turn in any direction, and cannot be rotated further. However, in the actual driving of the car, it is designed to rotate more than half a turn in any direction.
It is desirable to rotate the handle within a larger range of rotation angles.

The present invention has been made to solve such a conventional problem, and has a relatively simple structure in which a stopper is actuated after the handle has been rotated more than a half turn in any direction. The purpose is to provide a mechanism.

[Means for Solving the Problems]

According to the present invention, a handle for rotating operation, a pinion provided on the handle shaft, a locking arm protruding laterally with respect to the handle shaft, a pinion extending in a direction orthogonal to the handle shaft and meshing with the pinion. And a stopper member attached to both ends of the rack, the rack is held so as to reciprocate in the lengthwise direction by the rotation of the pinion, and the stopper member is engaged at the neutral position of the handle. Being located outside the rotational movement locus of the stop arm and entering the rotation movement locus of the above-mentioned locking member after the handle shaft has rotated more than half a turn in any direction from the neutral position, and the locking arm contacts the stopper member. The rotation of the handle is stopped by the.

The locking arm may project to both sides with respect to the handle shaft, and when the handle is rotated one and a half rotations, the locking arm may come into contact with the stopper member to stop the rotation.

[Action]

In the above configuration, the stopper member moves through the pinion and the rack by the operation of the handle, and the stopper member moves to a position where it abuts the locking arm provided on the handle shaft by rotating the handle to a certain extent or more. ,
It is possible to stop the handle after rotating the handle more than half a turn.

〔Example〕

In FIGS. 1 to 6, a handle shaft 20 of a handle 2 is inserted from one side (front wall 1a) into a box-shaped frame 1 having a built-in driving mechanism.
0 is rotatably supported by bearings 21 and 22 provided on the front wall 1a and the support plate 11 in the frame 1. A pinion 25 is formed at the tip of the handle shaft 20, and locking arms 23 projecting to both sides of the handle shaft 20 are attached to an intermediate portion of the handle shaft 20. A contact surface 23a for contacting a stopper member described later,
23b is formed.

Between the both side walls 1c of the frame 1, a pair of parallel guide rods 13 and 14 are arranged in a direction orthogonal to the handle shaft 20, and the guide rods 13 and 14 are provided with a pair of stopper members 3 respectively. It is movably penetrated through 34. A contact portion 33 made of a shock absorbing material such as rubber is formed at one end of the stopper member 3,
Further, the mounting members 55 are respectively provided on the stopper members 3.
Is attached, and both ends of the rack 5 are attached to the attachment member 55, whereby the rack 5 is arranged between the pair of stopper members 3. The pinion 25 at the tip of the handle shaft 20 meshes with the rack 5, and the rotation of the pinion 25 causes the rack 5 to reciprocate in the direction orthogonal to the handle shaft 20.

A shaft 6 parallel to the guide rods 13 and 14 is provided between them.
0 is arranged and the holder 6 is attached to the bottom wall 1d of the frame 1.
Both ends of the shaft 60 are held by 1. A spring 6 is attached around the shaft 60, and both ends of the spring 6 are supported by spring receivers 66.
The spring receivers 66 are respectively the guide rods 13,
14 is movably penetrated.

In the normal state, the spring receiver 66 is pressed against the holding body 61 by the extension force of the spring 6, and the stopper member 3
The spring 6 is configured to move when it is pushed in the central direction by being compressed.

Further, a holding frame 12 is attached between both side walls 1c of the frame 1,
A tachometer 40 is held by the holding frame 12, a pinion 4 is attached to the shaft of the tachometer 40, and the pinion 4 meshes with the rack 5.

In the above structure, when the handle 2 is operated, the pinion 2
The rotation of 5 moves the rack 5 meshing with it in the lengthwise direction, and the movement of the rack 5 rotates the pinion 4 meshing with it, and the rotation amount 40 measures the amount of rotation of the handle 2. An output (40) provides a driving (steering) operation of a car or the like displayed on a cathode ray tube (not shown).

In the neutral state of the handle 2, as shown by the solid lines in FIGS. 3 and 6, the stopper member contact portion 33 is not located in the rotation locus 100 of the locking arm 23. Therefore, within a certain range from the neutral state. During the rotation, the locking arm 23 does not contact the contact portion 33, and therefore the force for stopping the rotation of the handle 2 does not act. When the handle 2 is rotated to the left or right from the neutral state, the pinion 25 at the tip of the handle shaft 20 rotates and the rack 5 meshing with the pinion 25 moves in the longitudinal direction. For example, when the handle 2 is rotated counterclockwise (arrow direction) in FIG. 6, the rack 5 moves to the right, and the stopper members 3 connected to both ends of the rack 5 are moved.
Also move in the same way. As a result, the right spring receiver 66 is pressed against the holding body 61 and does not move, but the left spring receiver 6 is pressed by the stopper member 3 and moves to the right while compressing the spring 6. After the operation of the handle 2, the force of the spring 6 causes the stopper member 3 and the rack 5 to move through the spring receiver 66.
The force that always returns the to the neutral position will act.

When the handle 2 is rotated once, the locking arm 23 draws the rotation locus 100 shown in FIG. 6 and is in the state shown by the solid line (original state).
However, during this time, the contact portion 33 of the stopper member does not enter the rotation locus 100 of the locking arm 23, and the contact portion 33 rotates after the left end of the locking arm 25 passes the lower left side. Trail 1
It is configured to enter during 00. Therefore, when the rotation of the handle 2 reaches one and a half rotations, the contact surface 23a of the locking arm 26 contacts the contact portion 33 of the stopper member as shown by the phantom line in FIG. 6, and the rotation of the handle 2 is stopped. When the handle 2 is rotated in the opposite direction, the operation is exactly the same as the above case except that the left and right sides are reversed.

In the above-mentioned embodiment, the portion of the stopper member 3 which comes into contact with the contact portion 33 is symmetrical with respect to the locking arm 23 at two positions (the contact surface 23).
a, 23b), and an example in which the handle 2 is stopped when the handle 2 is rotated one and a half rotations is shown, but the rotation angle up to the stop can be variously set. For example, as shown by the phantom line in FIG. 6, instead of the locking arm 23, a locking arm 29 protruding only to one side (upward) is attached to the handle shaft 20, and while the locking arm 29 rotates 90 °, Instead of abutting against the stopper member, the rotation may be stopped by abutting against the abutting portion 33 of the stopper member when rotating once and 90 degrees. Alternatively, the locking arm 29 shown in FIG. 6 may be projected downward so as to contact the contact portion 33 of the stopper member when the handle 2 is rotated by 270 °.

〔The invention's effect〕

As described above, according to the present invention, the stopper member moves via the pinion and the rack by the operation of the handle, and the stopper member comes into contact with the locking arm provided on the handle shaft by rotating the handle to a certain extent or more. In order to move to the position, the handle can be rotated more than half a turn and then stopped. Therefore, with a relatively simple structure, it is possible to provide a realistic sensation that is close to the actual driving state of the vehicle.
