The transfer plate 10 is made of a core member 25, first and second reinforcing members 26, 30, first to third aluminum plates 27, 34, 35, a sheet member 28, and anti-slip rubbers 29A, 29B. Since these members are lightweight, the weight of the transfer plate 10 itself is light and can be easily carried.

  The procedure for using the transfer plate 10 will be described as follows, taking as an example a case where a person in a wheelchair gets on the rear loading platform 55 (in the vehicle) of the vehicle 53 from the road 52. Although not shown, the rear loading platform 55 of the car 53 has been modified to a specification that allows a wheelchair to enter. The assistant pushes the wheelchair to move the wheelchair to the vicinity of the back door 54 (back door) of the car 53, and the assistant carries the folded transfer board 10 and carries the transfer board 10 to the boarding position of the car 53. . The assistant turns the second side portion 16 of the plate members 11A, 11B downward and vertically so that the first side portions 15 of the plate members 11A, 11B face down, and is folded and folded. To prepare for use (use state in FIG. 1).

  Next, the assistant opens the rear door 54 of the car 53. Since the rear loading platform 55 of the car 53 is located above the road 52 and a large step is formed between the road 52 and the rear loading platform 55, the wheelchair cannot enter the rear loading platform 55 as it is. It is extremely difficult to move the wheelchair to the rear cargo bed 55 without using the plate 10.

  After the rear door 54 of the car 53 is opened, the edge 22 of the first end 13 of the plates 11A and 11B of the transfer plate 10 is grounded to the road 52 (one location), and the second ends of the plates 11A and 11B. 15 end edges 31 are grounded to the rear cargo bed 55 (the other part) in the vicinity of the rear door 54. By connecting the edges 22 and 31 of the first and second end portions 13 and 14 to the road 52 and the rear loading platform 55 of the car 53, the transfer plate 10 can be installed between the road 52 and the car 53, The transfer board 10 can be bridged between the road 52 and the car 53.

The first and second side portions 15 and 16 of the plate members 11 </ b> A and 11 </ b> B are located between the road 52 and the rear cargo bed 55 of the car 53, and straddle the step formed between the road 52 and the rear cargo bed 55.

  When the transfer plate 10 is bridged, a passage across the step between the road 52 and the rear cargo bed 55 is created. The edge 22 of the first end 13 of the plates 1A and 11B is grounded to the road 52, and the edge 31 of the second end 14 of the plates 11A and 11B is grounded to the rear loading platform 55 in the vicinity of the door 54 of the car 53. In this state, a predetermined space is defined between the lower surfaces 39 and 41 of the intermediate region 17 of the plate members 11A and 11B and the road 52 (the upper surfaces of those portions), and the upper surfaces 38 and 40 of the intermediate region 17 are A substantially flat passage is formed between the first end 13 and the second end 14.

  After bridging the transfer plate 10, the wheelchair located on the road 52 is pushed toward the transfer plate 10, and the wheelchair wheel is placed on the first end 13, against the upward slope of the upper surface 23 of the first end 13. The wheelchair is moved in the front-rear direction from the first end 13 side toward the second end portion 14 side. When the wheelchair is moved from the first end portion 13 toward the second end portion 14, the wheelchair passes from the first end portion 13 through the intermediate region 17 and beyond the second end portion 14 to the rear portion of the vehicle 53. Move to loading platform 55. When the wheelchair passes through the intermediate region 17, even if the wheelchair wheel is about to be derailed from the second side portions 16 of the plate members 11 </ b> A and 11 </ b> B by mistake in directionality, the derailment is prevented by the guard plate 36. After the wheelchair is moved to the rear loading platform 55 (inside the vehicle) of the electric vehicle 53, the transfer plate 10 is folded in the above-described procedure.

  When the wheelchair is moved from the rear loading platform 55 of the car 53 to the road 52, the transfer plate 10 is bridged between the road 52 and the rear loading platform 55 of the vehicle 53 in the same manner as when the wheelchair is put on the rear loading platform 55. The wheelchair located on the loading platform 55 is pushed toward the transfer plate 10, the wheelchair wheel is placed on the second end portion 14, and the wheelchair is moved against the upward slope of the upper surface 32 of the second end portion 14. It is moved in the front-rear direction from the side toward the first end 13 side. When the wheelchair is moved from the second end portion 14 toward the first end portion 13, the wheelchair moves from the second end portion 14 through the intermediate region 17 and beyond the first end portion 13 to the road 52. To do.

  Although the case where the transfer board 10 is used for getting on and off the car 53 has been described as an example, the transfer board 10 is not only used for getting on and off the car 53, but also a step between a roadway and a sidewalk that is difficult to pass by a wheelchair alone, between the entrance and the soil It can be used in various places such as a step between the floor and the floor, a step between the train platform and the inside of the train, and a crossing of a gutter on the road.

  In the transfer plate 10, the first end portions 13 of the plate materials 11 </ b> A and 11 </ b> B are tapered from the intermediate region 17 toward the edge 22 of the first end portion 13, and the second end portions 14 of the plate materials 11 </ b> A and 11 </ b> B are formed. Since the thickness thereof is tapered from the intermediate region 17 toward the edge 31 of the second end 14, the edge 22 of the first end 13 is grounded to the road 52 (one location), and When the edge 31 of the two end portions 14 is grounded to the rear loading platform 55 (the other location) of the vehicle 53, there is no step between the end portions 13 and 14 and the road 52 or loading platform 55. The wheelchair can be stably installed on the rear loading platform 55 of the vehicle 53, and the wheelchair can be smoothly moved from the road 52 to the rear loading platform 55 (inside the vehicle) of the vehicle 53 without trouble. To move smoothly from road to road 52 It can be. Since the transfer plate 10 can be stably installed and the wheelchair can be stably driven on the transfer plate 10, the wheelchair can be moved from the road 52 (one location) to the rear loading platform 55 (the other location). ) And the wheelchair can be safely moved from the rear cargo bed 55 to the road 52.

  Since the board | plate materials 11A and 11B are connected via the hinge 12, and the board | plate materials 11A and 11B can be folded so that the surface of these board | plate materials 11A and 11B may face each other, the delivery board 10 is necessary for carrying around. It can be easily carried to a place (a boarding / alighting position of the car 53) and can be used at the right place in a timely manner, and it can be flat over a place having a step or a groove where a wheelchair is difficult to pass. By forming a simple traffic path, it is possible to ensure smooth and safe movement of the wheelchair at those locations.

  In the transfer plate 10, the first and second end portions 13 and 14 include a first aluminum plate 27 in addition to the core material 25, and the first and second side portions 15 and 16 have second and third in addition to the core material 25. Since the first to fourth corner portions 18 to 21 include the first to third aluminum plates 27, 34, and 35 in addition to the core material 25, the four sides of the transfer plate 10 are provided with the aluminum plates 34 and 35. Unintentional deformation and buckling of the transfer plate 10 when a wheelchair with a predetermined weight, which is reinforced by the first to third aluminum plates 27, 34, and 35, passes over the transfer plate 10, is the aluminum plate. 27, 34, and 35, the safe travel of the wheelchair on the transfer plate 10 can be ensured. Further, the transfer plate 10 defines a frame structure in which the first to third aluminum plates 27, 34, and 35 extend to the peripheral edges of the plate materials 11 </ b> A and 11 </ b> B, and the frame structure defined by the aluminum plates 27, 34, and 35. Since the strength of the plate members 11A and 11B is improved, the frame structure prevents inadvertent deformation and buckling of the transfer plate 10 when a wheelchair with a predetermined weight on the person passes over the transfer plate 10. Safe traveling of the wheelchair on the transfer plate 10 can be ensured.
