Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a lifting device used when a wheelchair, a cart, etc. passes through a stepped portion. [Knowledge Technology] The known lift device has the technology shown in FIG. 4. This lifting device supports the lifting plate 5 3 on the chassis 5 1 through the X link mechanism 5 2, and an oil pressure cylinder 5 4 is inclined between the chassis 5 1 and the X link mechanism 5 2 to form an oil The pressure cylinder 54 drives the lift plate 53 between the low ground LF and the high ground UF. [Problems to be Solved by the Invention] However, according to this type of lifting device, since the X link mechanism 5 2 and the hydraulic cylinder 54 are stored in the lower side of the lifting plate 5 3 during the lowering, the lifting plate 5 3 cannot be lowered. Go to the position closest to the low ground LF. Therefore, in the past, it is necessary to attach a slope 55 on the front side of the chassis 5 1 or excavate low-level LF construction (not shown) and other auxiliary equipment. Wheelchairs and other inconveniences when climbing up and down the slope 5 5 and excavation construction equipment The high cost is also limited by the venue. Therefore, the problem to be solved by the present invention is to provide a lifting device which can use the mechanism of the lifting body so that the lifting plate can be lowered to the lowest ground. [Means for Solving the Problem] In order to solve the above problems, the lifting device of the present invention is a device used when passing through a stepped portion such as a wheelchair, a cart, and the like, and has a bottom frame installed on a low ground; The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 x 297 public love) Please read it first, read the back-notes rm it II Order printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs -4-526163 A7 __B7 _ V.

The base frame 1 is a thin-shell-shaped quadrangular frame formed by two side rails 6 provided on its left and right side edges and three flat bars 7 connecting the front and rear side rails 6. The lifting plate 2 is formed of a thin plate substantially the same as the base frame 1 with a non-slip sheet 8 affixed thereon, and protrusions 9 with side openings formed on the left and right side edges. The link mechanism 3 is composed of four pieces. The connection plate 11 is configured by connecting a pair of left and right X-shaped links 10. Then, the fulcrum shaft 12 of the upper and lower links 10 is provided at the end of the step portion 9 and the side rail 6 of the stepped portion, that is, the front end of the lifting device. The rollers 13 of the upper and lower links 10 are the protruding portions 9 and Guided by side rails 6. Two hydraulic cylinders 4 are vertically arranged between the chassis 1 and the lifting plate 2 in an inverted posture at the front end of the lifting device. The cylinder tube 1 5 is mounted on the fulcrum shaft 1 2 of the protrusion 9 through the bracket 1 6 Office. The piston rod 17 is formed in a hollow shape in order to supply hydraulic oil to the cylinder tube 15. The lower end of the piston rod 17 is connected to the chassis 1 through a flow regulating valve 18. Next, the left and right flow regulating valves 18 (only one side shown) are connected to the hydraulic components via piping 19. The two hydraulic cylinders 4 are expanded and contracted in the same stroke with the same amount of hydraulic oil. The lift plate 2 is arranged. The upper limit position (the solid line position in FIG. 2) and the lower limit position (the two dotted line positions in FIG. 2) near the low ground are formed at the lower limit position to store the link 10 of the X link mechanism 3 in the lower limit position. Inside the protrusion 9 (see FIG. 3). The flat rod 7 of the chassis 1 and the connecting plate 1 1 of the X-link mechanism 3 are assembled without overlapping each other. This paper applies the Chinese National Standard (CNS) A4 specification (210 X 297).

Description of the invention (4) The lower limit position, while the lift plate 2 is Overlaid on these components 7, 1 1 〇 There are 2 left and right handrails 2 2 which can be gripped by wheelchair users or pedestrians on the lifting board 2; cross plates 2 3 used when getting on and off wheelchairs on high ground; as undulations The levers 2 4 of the operating members of the cross-plate 23 are prevented from falling down, and the chain 25 is prevented. Each armrest 22 is bridged between the middle portion of the cylinder tube 15 and the rear end portion of the protruding portion 9 (on the fulcrum axis side), and the lever 24 is supported on one side of the armrest 22. The spanner plate 2 3 is rotatably mounted on the front edge end (side edge of the step portion) of the lifting plate 2 and is connected to the rod 24 by a thin rod material 2 6. In the above-mentioned lifting device, when the user moves the wheelchair to the step S, the lifting plate 2 is first placed at the lower limit position, and then the wheelchair is moved to the lifting plate 2 after the chain 25 is released. At this time, since the X-link mechanism 3 is housed inside the protruding portion 9, the lifting plate 2 is located very close to the low ground LF, which is equivalent to the minimum thickness of the lifting plate 2 and the flat rod 7 (less than 10 mm). In this position, the user can easily move the wheelchair from the low-level LF to the lifting plate 2 even without using a ramp. Next, the hydraulic cylinder 4 is extended to raise the lifting plate 2 to the upper limit position at the same height as the high ground U F in a horizontal state to stop, and the swing lever 24 rotates the span plate 2 3 to cross the high ground U F. In this way, there is no need to worry about the distance between the lifting plate 2 and the high ground U F hindering the movement of the wheelchair, and the user can easily lower the wheelchair to the high ground U F. When moving down to the step S, the lifting plate 2 is arranged at the upper limit position, so that the wheelchair is moved from the high floor U F to the lifting plate 2 by the cross plate 23, and the handrail 2 2 is tightly secured to ensure safety. Because the armrest 2 2 is installed by using the cylinder tube 1 5 This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (please read the precautions for xenon first to write this page) Printed by the Consumer Cooperatives of the Bureau 526163 A7 B7______ 5. The invention description (5) is produced, so it has the advantage of reducing the number of parts. Then, the hydraulic cylinder 4 is retracted, and the lifting plate 2 is lowered to a lower limit position in a horizontal state to stop, so that the wheel chair can be moved from the lifting plate 2 to a low floor L F. At this time, since the lifting plate 2 is disposed very close to the low floor LF, the user can smoothly move down from the lifting plate 2 to the low floor LF. In addition, the present invention is not limited to the above-mentioned embodiments. For example, instead of a hydraulic cylinder, a ball screw, a rack, a pinion, or a chain may be used. The present invention may be appropriately used without departing from the scope of the present invention. It is implemented by changing the shape and structure of each part. [Effect of the Invention] As described above, according to the lifting device of the present invention, the lifting plate can be lowered to the lowest level by the mechanism of the lifting body. Therefore, there is no need for a ramp, wheels, chairs, or carts can be easily moved up and down, which has the effect of reducing the installation space of the lifting device printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In addition, because excavation is not required, the equipment cost can be cheaper, and the installation site of the lifting device is not limited, so it is easy to move. Furthermore, because the driving means is installed vertically, it can efficiently transmit power. While the use of small diameter hydraulic cylinders can reduce costs, it also has the effect of eliminating speed changes during lifting and improving seat comfort.
