In the manufacturing method, since the urethane foam cured product is reinforced by the first and second reinforcing materials, a load of a predetermined weight of a wheelchair on which a person is placed is applied to the urethane foam cured product, and a force for bending the urethane foam cured product is applied. However, careless deformation and buckling of the urethane foam cured product can be prevented by these reinforcing materials, and a transfer plate capable of maintaining the form of the urethane foam cured product can be made. In the manufacturing method, the frame structure prevents inadvertent deformation and buckling of the plate-like member when a wheelchair with a predetermined weight on the person passes over the transfer board, and the wheelchair passes over the transfer board. Inadvertent deformation and buckling of the cured urethane foam when it is done is prevented by these reinforcements, so the roadway is flat across a stepped part or a grooved part where it is difficult for the wheelchair to pass. It is possible to form a wheelchair, to ensure safe traveling of the wheelchair, and to safely move the wheelchair from one location to the other. It is possible to make a transfer board that can be moved safely to any location. In the manufacturing method, after making the hollow plate-shaped member, urethane foam may be filled in the entire space between the reinforcing plates from the filling holes formed in either of the first and second reinforcing plates. The manufacturing cost of the plate can be greatly reduced.

  In the first step, the front end plate is fixed to the upper surface of the front end portion of the first reinforcing plate, the rear end plate is fixed to the upper surface of the rear end portion of the first reinforcing plate, and the upper surfaces of both side portions of the first reinforcing plate are fixed. The first side plate is fixed, the second side plate is fixed to the lower surface of both side portions of the second reinforcing plate, and the side opening that opens between the first and second reinforcing plates is covered by one of the first and second side plates. The manufacturing method of the connecting plate is formed of a front end plate, a rear end plate, and a first and second side plate that form a frame structure that extends to the periphery of the plate-like member, and is formed from the front and rear end plates and the first and second side plates. Since the strength of the plate-like member is improved by the frame structure and the urethane foam cured product is reinforced by the first and second reinforcing members, the wheelchair with a predetermined weight on which a person is placed passes over the transfer plate. Inadvertent deformation and buckling of the member In addition, the reinforcing material prevents inadvertent deformation and buckling of the urethane foam cured product when the wheelchair passes over the transfer plate, and places or grooves with steps that make it difficult for the wheelchair to pass. It is possible to form a flat passageway over the place where the wheelchair is made, to ensure safe driving of the wheelchair, and to move the wheelchair safely from one place to the other It is possible to make a transfer board that can safely move the wheelchair from one location to the other.

  In the first step, the first side plate, the front end plate, the first reinforcing plate, the second reinforcing plate, and the second side plate are arranged in the order of the first side plate, the front end plate, the first reinforcing plate, and the second side plate from the upper side in the vertical direction. Those that are firmly connected through the means and arranged in the third and fourth corners in the order of the first side plate, the rear end plate, the first reinforcing plate, the second reinforcing plate, and the second side plate from the top to the bottom in the vertical direction The manufacturing method of the transfer board which connects a board firmly through a predetermined connection means forms the strong frame structure extended to the periphery of a plate-shaped member by a front end plate, a rear end plate, and a 1st and 2nd side plate. Since the strength of the plate-like member is improved by the frame structure formed by the front and rear end plates and the first and second side plates, a wheelchair with a predetermined weight on which a person is placed passes over the plate-like member. The frame structure prevents inadvertent deformation and buckling of the plate-like member. Its flat shape can be maintained for a long period of time and can be produced passing plate does not lose the function as traffic channels. The manufacturing method is such that a frame structure prevents inadvertent deformation and buckling of a plate-like member when a wheelchair with a predetermined weight passing a person passes over the transfer plate, and has a step where it is difficult for the wheelchair to pass.

The manufacturing method of the connecting plate is formed of a front end plate, a rear end plate, and a first and second side plate that form a frame structure that extends to the periphery of the plate-like member, and is formed from the front and rear end plates and the first and second side plates. Since the strength of the plate-like member is improved by the frame structure and the urethane foam cured product is reinforced by the first and second reinforcing members, the wheelchair with a predetermined weight on which a person is placed passes over the transfer plate. Inadvertent deformation and buckling of the member In addition, the reinforcing material prevents inadvertent deformation and buckling of the urethane foam cured product when the wheelchair passes over the transfer plate, and places or grooves with steps that make it difficult for the wheelchair to pass. It is possible to form a flat passageway over the place where the wheelchair is made, to ensure safe driving of the wheelchair, and to move the wheelchair safely from one place to the other It is possible to make a transfer board that can safely move the wheelchair from one location to the other.

The manufacturing method of the transfer board which connects a board firmly through a predetermined connection means forms the strong frame structure extended to the periphery of a plate-shaped member by a front end plate, a rear end plate, and a 1st and 2nd side plate. Since the strength of the plate-like member is improved by the frame structure formed by the front and rear end plates and the first and second side plates, a wheelchair with a predetermined weight on which a person is placed passes over the plate-like member. The frame structure prevents inadvertent deformation and buckling of the plate-like member. Its flat shape can be maintained for a long period of time and can be produced passing plate does not lose the function as traffic channels. The manufacturing method is such that a frame structure prevents inadvertent deformation and buckling of a plate-like member when a wheelchair with a predetermined weight passing a person passes over the transfer plate, and has a step where it is difficult for the wheelchair to pass. It is possible to build a flat passageway over the part where the groove is made, and it is possible to secure the safe driving of the wheelchair and to safely move the wheelchair from one place to the other place. It is possible to make a transfer plate that can be moved and can safely move the wheelchair from one location to the other.

  In the first step, the manufacturing method of the transfer plate for fixing the non-slip sheet to the upper surface of the first reinforcing plate is a wheelchair for the plate-like member when a wheelchair with a predetermined weight passing on the plate-like member passes over the plate-like member. An inadvertent slip is prevented by the non-slip sheet, and it is possible to ensure a safe driving of the wheelchair, and it is possible to safely move the wheelchair from one place to the other, A transfer board that can be safely moved from one point to the other can be made.

  In the first step, the front end portions of the first and second reinforcing plates are tapered toward the front end edge, and the rear end portions of the first and second reinforcing plates are tapered toward the rear end edge. However, in the manufacturing method of the transfer plate that is formed in a downward slope at a predetermined inclination angle, the front end portions of the first and second reinforcing plates are tapered toward the front end edges, and the first and second reinforcing plates are formed. Since the thickness of the rear end portion of the plate-like member is tapered toward the rear end edge, the front end edge of the front end portion of the plate-like member is grounded to one place, and the rear end edge of the rear end portion of the plate-like member is When the other part is grounded, there is no step between the front and rear ends of the plate-like member and those parts, and it is possible to stably install them at those parts. It is possible to move smoothly from one location to the other Both can make passing plate capable of smoothly moving to one location a wheelchair from the other locations. In the manufacturing method, since the rear end portions of the first and second reinforcing plates are formed in a downward slope at a predetermined angle toward the rear end edge, an obstacle is provided at the other location where the rear end portion of the plate-like member is grounded. Even if there is, the rear end of the plate-like member gets over it and the rear edge is stably grounded to the other location, and the rear end of the plate-like member does not ride on the obstacle, The wheelchair can be stably installed, the wheelchair can be stabilized, and the wheelchair can be safely moved from one place to the other. It is possible to make a transfer board that can be moved safely to any location.

When the wheelchair passes through the intermediate region 17, the guard plate 39 prevents the wheel from being removed even if the wheel of the wheelchair is likely to be removed from the second side portion 16 of the plate-like members 11 </ b> A and 11 </ b> B. The After the wheelchair is moved into the train 63, the transfer board 10 is folded in the above-described procedure, and the transfer board 10 is carried to the storage location.

  When moving the wheelchair from the inside of the train 63 to the platform 62, the transfer board 10 is bridged between the platform 62 and the inside of the train 63, as in the case of getting the wheelchair into the train 63. Push the wheelchair located at the transfer plate 10, place the wheelchair wheel on the second end 14, and move the wheelchair from the second end 14 side against the ascending slope of the upper surface 33 of the second end 14. It is moved in the front-rear direction 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 to the home 62 beyond the first end portion 13. To do.

  Although the case where the transfer board 10 is used for getting on and off the train 63 has been described as an example, the transfer board 10 is not only used for getting on and off the train 63 but also a step between a roadway and a sidewalk that is difficult to pass by a wheelchair alone, and between the entrance and the dirt. It can be used in various places such as a level difference between the vehicle and the floor, a level difference between the inside and outside of the vehicle, and a crossing of a side ditch on the road.

  In the manufacturing method of the transfer plate 10, the foamed urethane 58 is filled in the entire space 27 between the first and second reinforcing plates 25 and 26, and the foamed urethane is filled in the space 27 between the first and second reinforcing plates 25 and 26. Since the cured urethane foam 28 having the cured 58 is interposed, the weight of the transfer plate 10 can be reduced compared with the case where the plate-like member is made only of reinforced plastic, and can be easily carried. Thus, it is possible to make the transfer plate 10 that can be easily and quickly installed at a necessary place (a boarding position of the train 63).

  In the manufacturing method, a first to fourth aluminum plates 29, 35, 36, and 37 form a frame structure that extends to the periphery of the plate-like members 11A and 11B. Since the strength of the plate-like members 11A, 11B is improved by the frame structure formed from the end plate, the first side plate, and the second side plate, a wheelchair with a predetermined weight passing a person passes over the plate-like members 11A, 11B. Inadvertent deformation and buckling of the plate-like members 11A and 11B during the operation are prevented by the frame structure, the flat shape can be maintained for a long time, and the function of the passageway is not lost. Can be manufactured.

  In the manufacturing method, since the urethane foam cured product 28 is reinforced by the first and second reinforcing members 25 and 26, a load of a predetermined weight wheelchair on which a person is placed is applied to the urethane foam cured product 28. Even if the bending force is applied, the reinforcing members 25 and 26 prevent the urethane foam cured product 28 from being inadvertently deformed or buckled, and the urethane foam cured product 28 can maintain its form. Can be made.

  In the manufacturing method, the frame structure prevents inadvertent deformation and buckling of the plate-like members 11A and 11B when a wheelchair of a predetermined weight carrying a person passes over the transfer plate 10, and the wheelchair is used as the transfer plate. Since the reinforcing members 25 and 26 prevent inadvertent deformation and buckling of the urethane foam cured product 28 when passing over the top 10, a portion or groove having a step that makes it difficult for the wheelchair to pass through was created. It is possible to form a flat passageway over the place, to ensure the safe driving of the wheelchair, and to move the wheelchair from one place to the other safely Yes, it is possible to make a transfer plate that can safely move the wheelchair from one location to the other location. In the manufacturing method, after forming the hollow plate-like members 11A and 11B, the urethane foam 58 is filled in the entire space 27 between the reinforcing plates 25 and 26 from the filling holes 59 formed in the second reinforcing plate 26. Well, the manufacturing cost of the transfer plate 10 can be greatly reduced.

  The manufacturing method is such that the front end portions of the first and second reinforcing plates 25 and 26 are tapered toward the front end edge, and the rear end portions of the first and second reinforcing plates 25 and 26 are rear end edges. Since the thickness of the plate-shaped members 11A and 11B is tapered toward the front, the front edge of the front ends of the plate-like members 11A and 11B is grounded to one place, and the rear edge of the rear ends of the plate-like members 11A and 11B There is no step between the front and rear ends of the plate-like members 11A and 11B and those places when grounded at the places, and the transfer plate 10 that can be stably installed at these places can be made.

  In the manufacturing method, since the rear end portions of the first and second reinforcing plates 25 and 26 are formed in a downward slope at a predetermined angle toward the rear end edges, the rear end portions of the plate-like members 11A and 11B are grounded. Even if there is an obstacle at the other location, the rear ends of the plate-like members 11A and 11B get over it, and the rear edge is stably grounded to the other location, and the rear ends of the plate-like members 11A and 11B It is possible to make the transfer plate 10 that can be stably installed at a predetermined location without the part climbing over an obstacle.
