Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brake mechanism attached to a handle portion of a simulated operation game machine such as a motorcycle.

[0002]

2. Description of the Related Art As a brake lever simulation mechanism of a conventional motorcycle simulation control game machine, there is Japanese Patent Application No. 2-139930.
In the above technique, the brake lever has a mechanism in which a screw is rotatably supported at the base of the brake lever with a fulcrum, and is returned by a spring mounted between the brake lever and the base.

[0003]

In the above mechanism, the resistance when the brake lever is gripped is always maintained by the tension spring, so that the resistance is always constant, which is different from the actual motorcycle brake lever mechanism. Like the brake lever, I did not feel the pressure to repel as I gripped the lever deeply. Therefore, the present invention is to provide a mechanism for expressing a more actual brake lever feeling.

[0004]

In order to achieve the above object, in the present invention, the substantially L-shaped long side portion of the substantially L-shaped brake lever is made parallel to the accelerator grip, and the substantially L-shaped short side portion is formed. The substantially L-shaped corner portion is rotatably attached to the shaft erected on the mounting base toward the accelerator grip side, and the rubber stopper is opposed to the short side portion in the rotation direction of the short side portion of the brake lever. Is provided. A bracket facing the short side portion in the direction of rotation of the short side portion is provided on the mounting base near the axis of the short side portion of the brake lever, and the limit switch detects the limit switch on the short side portion on the mounting base. It was provided with one piece facing.

[0005]

The operation of the above means will be described. When the brake lever is first pulled, the rubber stopper comes into contact with the short side of the brake lever to elastically deform the rubber stopper, and further to grasp the brake lever. When going, the abutting part of the rubber stopper and the short side part gradually bites into the rubber stopper and both sides of the rubber stopper bulge and deform, and the restoring force of the rubber stopper increases according to the degree of this deformation, and the brake lever's restoring force increases. Gives a grip on the grip.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The braking mechanism of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing an internal mechanism of a handle portion of a motorcycle, in which the center of an inverted trapezoidal base 1 having an upper side slightly longer than a lower side. A mounting hole 2 for a handle is provided in the portion, and bearings are provided at symmetrical positions on both side surfaces. A grip 4 is axially fixed to the bearing 3 on the left side. The bearing 5 on the right side has the rotating shaft 6a of the accelerator grip 6 inserted therein and is rotatably attached. The spiral spring 7 is wound around the rotating shaft 6a and the rotating angle is about 30 degrees. When 6 is rotated by hand, it rotates against the spiral spring 7, and when released, it returns to its original position. A gear 8 is attached to the end of the axle 6b of the accelerator grip, a bracket 9 is attached to the base 1, a volume 10 is attached to the bracket 9, and a gear 11 is attached to a rotary shaft 10a of the volume 10. Then, the rotation of the accelerator grip 6 can be detected by the volume 10 by engaging with the gear 8.

At the upper right corner of the base 1, a mounting base 12 having a flat surface whose inclination increases from the front side toward the accelerator grip is provided on the base 1, and a brake lever mechanism is mounted on the mounting base 12. is there. The left side piece 12a of the mount 12 is bent upward. The brake lever 13 has a substantially L-shape, and the substantially L-shaped long side portion 13a is parallel to the accelerator grip 6 and the substantially L-shaped short side portion 13b is directed toward the accelerator grip side. Shaft 14 with the part standing upright on the mounting base
It is rotatably attached to the shaft 14, and a helical spring 15 is wound around the shaft 14 to urge the brake lever 13 counterclockwise.
A round mountain-shaped rubber stopper 16 close to a cone is screwed to the left side piece 12a of the mounting base toward the short side portion 13a of the brake lever. The rubber stopper 16 faces the short side portion 13a with a slight gap.

When the brake lever 13 is gripped, the short side portion 13b of the brake lever comes into contact with the rubber stopper 16. Near the shaft 14 of the short side portion 13a of the brake lever, a bracket 17 is provided on the left side piece 12a parallel to the surface of the mounting base.
Limit switch 18 is attached to the brake lever
When 13 is gripped, the short side portion 13b comes into contact with the detection piece 18a of the limit switch 18 and pushes the detection piece 18a to push the brake lever 13b.
The operation of is detected. FIG. 2 is a plan view of the brake mechanism for explaining the brake operation. When the operator pulls the brake lever 13, the brake lever 13 causes the spiral spring 15
Counterclockwise around the shaft 14, the long side 13a of the long side approaches the accelerator grip 6, the short side 13b abuts the rubber stopper 16, and when the brake lever 13 is further pulled, the short side 13b is reached. Is to elastically deform the rubber stopper 16.

When the brake lever 13 is further pulled, the short side portion 13b of the brake lever comes into contact with the detection piece 18a of the limit switch and the limit switch 18 is turned on. By further pulling the brake lever 13 deep, the short side 13b
Further elastically deform the rubber stopper 16. Due to the elastic deformation of the rubber stopper 16, only a small force is required at first, but a large force is required to further elastically deform the rubber stopper 16 by pulling the brake lever 13, and the force for elastic deformation gradually increases. It is becoming.

When the brake lever 13 is first pulled, the restoring force of the spiral spring 15 acts as a drag force on the brake lever 13, which represents the play of the actual brake lever. Then, the short side portion 13a of the brake lever comes into contact with the crest of the rounded mountain of the rubber stopper 16 to start elastic deformation of the rubber stopper, and when the brake lever 13 is further grasped, the contact portion between the rubber stopper 16 and the short side portion 13b Then, the rubber stopper 16 gradually bites into the rubber stopper 16 and both sides of the rubber stopper 16 expand and deform, and the restoring force of the rubber stopper 16 increases according to the degree of deformation.

In the above embodiment, the rubber stopper 16 has a round mountain shape, but it may have a cubic shape, a rectangular parallelepiped shape or a cylindrical shape, and the shape is not particularly limited. This is because the elastic deformation of the rubber stopper 16 is mainly used for the repulsive force. Further, in the embodiment, the limit switch is used to detect the grip of the brake lever in two stages of OFF and ON, but the movement of the brake lever may be detected in analog by volume detection.

[0012]

By a series of operations of pulling the brake lever, the short side portion of the brake lever is elastically deformed against the rubber stopper, and the repulsive pressure becomes stronger as the brake lever is deeply gripped like a real brake lever. The feeling comes out.
