[0005] Still another conventional flap raising / lowering device (not shown) for a step-eliminating lift is one which manually raises and lowers a flap by operating a wire or link mechanism.

[0006] A vehicle elevator mounted on a vehicle includes:
The vehicle is provided with a lifting platform that moves up and down in order to get a vehicle wheelchair on and off and load and unload luggage. A vehicle elevator generally mounted on a vehicle is provided with a flap raising and lowering device. The flap raising and lowering device has a flap attached to an end of the lifting platform so as to be capable of lifting and lowering. When a wheelchair, luggage, or the like is moved on the elevator, the flap is folded down. When the elevator is raised, the flap is raised to prevent the wheelchair, luggage, or the like from falling.

A flap raising and lowering device for a vehicle elevator mounted on a vehicle is disclosed in Japanese Patent Application Laid-Open No. 7-300043. FIG. 13 shows a flap raising and lowering device of a vehicle elevator mounted on a vehicle disclosed in Japanese Patent Application Laid-Open No. 7-300043, and shows a state where the ends of left and right grounding operation lever plates of the flap raising and lowering device are in contact with the ground. It is a part side view.
FIG. 14 is a side view of a main part showing a flap raising and lowering device of a vehicle elevator mounted on the vehicle shown in FIG. 13 and showing a state in which an elevator is lowered.

A flap raising and lowering device for a vehicle elevator mounted on a vehicle shown in FIGS. 13 and 14 is provided with a support shaft 6 which projects in parallel at a required interval before and after a riding portion 1a of an elevator 1. A left and right grounding operation lever plate 8 provided with a grounding portion 8a at the front end thereof is mounted on the front supporting shaft 6 on the rear supporting shaft 7 so as to be rotatable.
Is pivotally disposed inside or outside the flap left and right levers 2a, and a tip 2b extending from the shaft support of the flap left and right levers 2a and a tip 8b of the left and right grounding operation lever plate 8 intersect at a required width. An engaging shaft 9 is provided at a distal end 2b extending from the pivotal support of the flap left and right lever 2a, and the distal end 8b of the left and right ground operation lever plate 8 is provided.
And a torsion bar (not shown) having one end fixed to the riding portion 1a of the lifting platform 1 and the other end to the right and left grounding operation lever plate 8. The right and left grounding operation lever plate 8 is urged in a clockwise direction by contacting the upper surface.

The flap raising and lowering device of the vehicle elevator mounted on the vehicle shown in FIGS. 13 and 14 operates as follows.
As shown in FIG. 13, when the elevator 1 descends, the elevator 1
Before the grounding, the tip of the grounding portion 8a of the left and right grounding operation lever plate 8 is grounded to the ground G. Subsequently, when the elevating platform 1 is further lowered, the right and left grounding operation lever plates 8 are pushed up by the ground G and countered about the support shaft 6 against the urging force of the torsion bar (not shown) as shown in FIG. The flap left and right levers 2a connected to the left and right grounding operation lever plates 8 via the engagement shafts 9 and the engagement holes 10 in conjunction with the rotation of the left and right grounding operation lever plates 8 rotate in the clockwise direction. The flap 2 is turned down around the center 7 in a clockwise direction. As a result, a step between the riding portion 1a and the ground G in the elevator 1 is reduced, and a wheelchair or the like can easily move between the riding portion 1a and the ground G. When the elevator 1 on which a wheelchair or the like is loaded is raised, as shown in FIG. 13, the left and right grounding operation lever plates 8 are moved by the urging force of a torsion bar (not shown).
The left and right flaps 2 connected to the left and right grounding operation lever plate 8 via the engagement shaft 9 and the engagement hole 10 in conjunction with the rotation of the left and right grounding operation lever plate 8
a rotates counterclockwise about the support shaft 7 to raise the flap 2. In addition, the engagement hole 1 of the left and right ground operation lever plate 8 is provided.
When the engaging shaft 9 of the flap left / right lever 2a abuts on one end of the flap left / right lever 2a, the flap left / right lever 2
Each rotation of a stops, and the flap 2 is maintained in the upright state. Thus, it is possible to prevent a wheelchair or the like from dropping from the elevator 1 while the elevator 1 is rising (or descending).

[0010]

However, FIG.
The flap raising and lowering device of the step-eliminating lift shown in (1) uses the actuator 3, and thus has a problem of a large increase in cost.

The flap raising and lowering device of the step-eliminating lift shown in FIGS. 11 and 12 is designed such that the bell crank 4 is rotated clockwise by a biasing means such as a spring (not shown) to raise the flap 2 via the link 5. Therefore, there is a limit to the force against the force of the wheelchair pushing down the flap 2 from above the elevator 1 (that is, the urging force of a spring or the like), and the wheelchair falls down from the elevator 1 by pushing down the flap 2. There was a problem that there was a possibility.

In the above-described flap hoisting device (not shown) of a conventional lift for lifting a flap by manually operating a wire or a link mechanism, it is difficult for a person in a wheelchair to hoist the flap. There was a problem that it is.

In the flapper hoisting / lowering device for a vehicle elevator shown in FIGS. 13 and 14, the engaging shaft 9 and the engaging hole 10 slide when the flapper 2 moves up and down. There is a problem that the left and right grounding operation lever plates 8 slide on the ground G and damage the ground G.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and to provide a flap raising / lowering apparatus for a step eliminator in which the structure is simple and the flap raising / lowering operation is automatically and reliably performed. It is.

[0015]

According to the present invention, there is provided a flap raising / lowering apparatus for a step-eliminating machine having a flap which is attached to one end of a lift table so as to be capable of raising and lowering, wherein the flap is integrally protruded from one side thereof. A pressing member is attached to one side of one end of the lift table so as to be vertically movable or swingable in a vertical plane, and the pressing member has a first end surface and a first end surface. And a second end surface substantially perpendicular to the first end surface and a ground contact portion, wherein the arm abuts on the first end surface when the flap stands up, and the arm contacts the second end surface when the flap falls down. This is configured so as to abut or oppose.

[0016]

When the elevator is moving up or down, the grounding portion of the pressing member is separated from the floor or the ground, so that the pressing member is lowered by the urging force of the urging means or the weight of the pressing member and is positioned below. The tip of the arm abuts on the first end face of the pressing member, whereby the flap is held upright. Therefore, a wheelchair or the like on the elevator is prevented from falling from the elevator. Also, in this state, even if a force in the falling direction acts on the flap by a wheelchair or the like,
Since the contact surface between the first end surface of the pressing member and the arm of the flap is substantially parallel to the movable direction of the pressing member, the upright state of the flap is reliably ensured. Further, in this state, since the position of the center of gravity of the flap including the arm is located outside the center of rotation of the flap, a clockwise rotation moment around the center of rotation of the flap due to the weight of the flap including the arm is applied to the flap. The flap does not fall down to the elevator side.

When the lifting platform is lowered, the pressing member is pushed up by the floor or the ground against the urging force of the urging means or the weight of the pressing member, and the distal end of the arm and the first end surface of the pressing member come into contact with each other. Is released, and the flap is rotated clockwise by its own weight to be in a falling state substantially parallel to the floor or the ground. In this state, the distal end of the arm abuts or faces the second end surface of the pressing member. Therefore, in this state, a wheelchair or the like can be moved from the elevator to the floor or the ground, or from the floor or ground to the elevator.
