The radius of gyration R1 of the upper link mechanism 24 is set shorter than the radius of gyration R2 of the lower link 25, and the elevating member 21 is inclined backward from the vertical attitude in association with the ascent. The bar 30 is thereby inclined up toward the front from the horizontal attitude.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stand for a motorcycle used to lift the entire vehicle body or one of the front and rear sides of the vehicle body and to maintain the lifted state when the tires of a motorcycle are replaced during a race. Regarding

There is an actuator driving method using a pneumatic cylinder or the like as described in Japanese Patent No. 3 publication.

The basic structure of any of the stands is a base, a fixed support fixed to the base in an upright posture, an elevating member supported by the fixed support so as to be vertically movable, and a cantilever on the elevating member. The bar is supported and extends horizontally. This bar can be inserted into a hollow pipe portion formed in the axle of the motorcycle or a hollow pipe portion formed in the engine portion.

When carrying out the lifting work of the motorcycle, first, the bar at the lowered position is inserted into the hollow pipe portion of the motorcycle in the grounded state, and the lifting member is raised manually or by the operation of the actuator. Lift the entire motorcycle or one of the front and rear.

The cantilevered bar is inserted into the hollow tube portion of the motorcycle in a horizontal posture, and is maintained in a horizontal posture even in a raised position.

In the latter actuator drive system, the pneumatic cylinders are arranged in a biased manner at the rear end of the base, and are arranged in an upright posture so as to extend substantially along the fixed columns. .

[0007]

As described above, in the structure in which the cantilevered bar is maintained in the horizontal posture even in the ascended position as in the lowered position, the weight of the motorcycle is heavy because the motorcycle is a heavy object. Therefore, when the bar tip side is bent so as to be lowered, the motorcycle is displaced during the work, and it cannot be said that the motorcycle is sufficiently supported.

In the actuator drive system,
If the pneumatic cylinders and the like are arranged so as to be biased toward the fixed column and in the standing posture, the position of the center of gravity of the stand becomes higher as it moves closer to the rear of the stand, and the stability especially during movement is not very good.

The object of the present invention is to improve the stability of the stand itself and the stability of the motorcycle when it is lifted.
It is also possible to secure a wide storage space for the motorcycle.

In order to solve the above-mentioned problems, the invention according to claim 1 of the present application is such that a base, a fixed support fixed to the base in an upright posture, and a movable up and down on the fixed support. A motorcycle provided with a supported lifting member, a bar that is cantilevered by the lifting member, extends substantially parallel to the base and can be inserted into the hollow tube portion of the motorcycle, and an actuator for lifting the lifting member. In addition, when the bar is in the raised position, a tilt control mechanism is provided to control the bar so that the tip side is above the fixed side.

According to a second aspect of the present invention, a base, a fixed pillar fixed to the base in an upright posture, an elevating member supported by the fixed pillar so as to be vertically movable, and cantilevered by the elevating member. In a motorcycle equipped with a bar that extends substantially parallel to the base and can be inserted into the hollow tube portion of the motorcycle, and an actuator for moving the lifting member up and down, an actuator having a telescopic drive member is provided along the base. It is characterized in that it is arranged in a laid-down posture, and an elevating member is connected to the telescopic drive member via a bell crank.

According to a third aspect of the present invention, in the motorcycle stand according to the first aspect, the elevating member is movably supported by the fixed column via the upper and lower link mechanisms, and the length of the upper link mechanism is set to the lower side. The tilt control mechanism is characterized by being adjustable so as to be shorter than the length of the link mechanism.

According to a fourth aspect of the present invention, in the motorcycle stand according to the first aspect, a damper mechanism, which is reduced by a load equal to or more than a predetermined load, is provided as an inclination control mechanism at an end of the base on which the fixed column is arranged. The feature is that it is provided.

According to a fifth aspect of the present invention, in the motorcycle stand according to the second aspect, an elevating member is disposed between the fixed columns, and an up-and-down link mechanism that swings up and down in a vertical plane substantially the same as the fixed columns. Thus, the lifting member is supported so as to be able to move up and down.

[0015]

By moving the entire stand in the protruding direction of the bar, that is, in the forward direction, the horizontal bar in the lowered position is inserted into the horizontal horizontal hollow tube portion of the motorcycle. When the telescopic drive member such as the telescopic rod is extended rearward by driving the actuator, the drive force is converted into the upward drive force via the bell crank and applied to the elevating member. As a result, the bar ascends together with the elevating member and lifts the entire motorcycle or one of the front and rear sides.

When the bar is moved to the raised position, the inclination control mechanism controls the attitude of the bar so that the tip of the bar is in the upward direction. Therefore, even if the bar bends due to the weight of the motorcycle, the motorcycle does not shift to the tip side of the bar.

Since it has a tilt control mechanism that controls the tilt posture so that the side is higher than the fixed side, when lifting the motorcycle,
Even if the bar bends due to its weight, the motorcycle can be supported in a stable state.

According to the second aspect of the present invention, in order to drive the elevating / lowering member to which the bar is attached, the actuator having the expansion / contraction drive member is arranged on the base in a lying posture, and the expansion / contraction drive member is provided with a bell crank. Since the lifting members are connected with each other, the position of the center of gravity of the entire stand is lower and the front, rear, left, and right widths of the stand are smaller than in the conventional structure in which a vertically oriented actuator is arranged near the fixed column. It can be configured so as to come to the center portion, and like the invention according to claim 1, the motorcycle can be supported in a stable state and the stability during movement is also improved.

Useful for saving the number of parts and simplifying the structure.

Since the tilt control mechanism is constructed by making the length of the upper link mechanism shorter than the length of the lower link, the structure is simple and the difference in the turning radii of the upper and lower link mechanisms results. It is possible to gradually incline in proportion to the elevation of the elevating member, and there is no impact due to a sudden inclination.

According to the fourth aspect of the present invention, as the tilt control mechanism, a damper which is reduced by a load equal to or more than a predetermined load is provided at the end portion on the fixed column arrangement side, and the weight of the motorcycle is used to make a stand. The structure is simple if the bar is tilted together.

According to a fifth aspect of the present invention, the elevating member is arranged between the fixed columns, and the elevating member is movably supported by an up-and-down link mechanism that vertically swings in substantially the same vertical plane as the fixed columns. By doing so, a large space on the front side of the fixed column, that is, a space for disposing the motorcycle can be secured, and tire replacement work and the like can be facilitated.
