[0012]
【Example】
Hereinafter, the present invention will be described with reference to the drawings which are embodiments. The rail frame 2 is attached to the outside of the side support plate 1a provided on both sides of the lifting platform 1, and the rollers 3, 4 guided by the rail frame 2 are moved forward and backward. The arranged sliders 5 are arranged on both sides, and the sliders 5 are pivotally attached to the distal ends of swing arms 7 and 8 arranged on the vehicle 6 with support shafts 9 and 10, and the whole is supported so as to be movable up and down. The other end of the proportional link 12 whose one end is connected to the lifting platform 1 with the support shaft 11 is connected to one swing arm 7 with the support shaft 13, and the slider 5 is proportional to the swing angle of the swing arms 7, 8. It moves back and forth, and is connected so that the raising and lowering of the raising and lowering platform 1 is vertical.
[0013]
A shaft mounting frame 14 is provided inside the slider 5, a rear end of the undulating rod 16 is inserted into a mounting hole 15 of the shaft mounting frame 14, and an expansion type is provided between the rear end of the undulating rod 16 and the shaft mounting frame 14. An adjustment coil spring 17 is interposed, and when the slider 5 moves forward, the hoisting rod 16 is pulled in that direction.
[0014]
At the distal end portions of the side support plates 1a on both sides of the lifting platform 1, support plates 18a and 18b are arranged in parallel with a predetermined interval on the front outer surface side of the side support plate 1a, and the support plates 18a, A support shaft 21 is used to support the intermediate portion between the base portion 22a and the front end portion 22b of the flapper 22 with the support shaft 21 supported by the support shaft 19 supported by the support shaft 18b. The front end of the operating rod 24 supported by the support plates 18a and 18b with the support shaft 23 reaches the flapper 22 from the upper side of the support shaft 19, and the support shaft 25 is pivotally connected to the base portion 22a. Equipped with flapper 22 up and down freely.
[0015]
The relay link 26 supports the lower half portion of the support plates 18a and 18b with the support shaft 27 behind the operation rod 24 and the support shaft 28 provided at the front end of the upper half to the rear of the operation rod 24. The upper connecting hole 30 and the lower connecting hole 31 are provided at the rear end of the upper half, and the connecting rod 33 a is connected to the upper connecting hole 30 by the support shaft 32 a . The connecting rod 33 is connected to the tip of the undulating rod 16 via a support shaft 34. The support shaft 32 b fitted into the lower connection hole 31 connects the tip of the return rod 36 around which the return spring 35 is wound. The proximal end of the return rod 36 is passed through and supported by a support shaft 37 that is loosely supported by the support plates 18 a and 18 b, and the pressure of the return spring 35 is applied to the leading flange portion 36 a that is connected to the support shaft 32.
[0016]
A support shaft 34 for connecting the connecting rod 33 and the undulating rod 16 is loosely fitted in a guide hole 38 provided in the support plates 18a and 18b and guided back and forth. Reference numeral 39 denotes a spring receiving lock screw.
[0017]
Since the present invention is configured as described above, the lifting platform 1 that moves up and down by the action of the swing arms 7 and 8 is moved up and down substantially vertically by moving the slider 5 with the proportional link 12 to correct the lifting locus. It is. When the swing arms 7 and 8 are lowered, the slider 5 moves to the tip side, so the shaft mounting frame 14 on the slider 5 similarly moves to the tip side and pulls the hoisting rod 16 that has been free until then. Therefore, the relay link 26 is compressed through the linkage 33 around the support shaft 27 and the return spring 35 is compressed and rotated rearward, and the rear end of the operation rod 24 is pushed up around the support shaft 23 to Is rotated downward and pushed down, the flapper 22 supported by the armband 20 is brought down and set in the boarding state. Considering the fact that the road surface is uneven, the flapper 22 is made to fall quickly, and even if the undulating rod 16 cannot be pulled by grounding, the adjustment coil spring 17 is compressed and the slider 5 moves, and the lifting platform 1 is moved. It comes to be grounded.
[0018]
Next, when the elevating platform 1 is raised by the action of the swing arms 7 and 8, the flapper 22 is automatically raised and raised by the reverse operation described above, and the final standing state is a retractable state. become.
[0019]
The flapper 22 may be raised and lowered by operating according to a hydraulic power mechanism that is operated by a switch that opens and closes the hoisting rod 16 according to the swing angle of the swing arm 7 or a switch that is manually opened and closed.
[0020]
【The invention's effect】
Since the present invention is as described above, the flapper of the lifting platform is automatically brought down to the boarding state or automatically standing in relation to the lifting platform manually or in connection with the operation of the swing arm. This will cause the vehicle to stop getting off.
