  In the conventional configuration described above, it is necessary for the wheel to get over the rotating shaft portion of the hinge when the wheelchair is put on, and the wheelchair cannot be put on smoothly.

  In view of the above, an object of the present invention is to provide a slope structure that can smoothly ride a wheelchair.

  In order to achieve the above object, the present invention is a slope structure that assists a wheelchair to get on and off a vehicle entrance and exit, and includes a vehicle floor, a slope plate, and a hinge. The slope plate has a landing surface. The hinge has a rotation shaft portion extending in the opening width direction of the entrance / exit on the passenger compartment side of the entrance / exit, and connects the floor surface and one end portion of the slope plate so as to be rotatable about the rotation axis of the rotation shaft portion. The slope plate extends from the entrance / exit to the outside of the passenger compartment and is bridged on the road surface. The development position is such that the entrance / exit surface is exposed upward, and is reversed from the deployment position around the rotation axis and accommodated inside the entrance / exit. The storage position can be set at the storage position where the boarding / alighting surface faces downward and faces the floor surface.

  The rotating shaft portion protrudes upward with respect to the landing surface of the slope plate at the deployed position. At one end of the hinge or slope plate, it extends in the opening width direction between the rotation shaft portion and the boarding / exiting surface, protrudes lower than the rotation shaft portion with respect to the boarding / exiting surface, and has a step with respect to the boarding / exiting surface more than the rotation shaft portion. Reduced hook-shaped ridges are formed.

  In the above configuration, when the wheelchair is on the wheel, the wheel of the wheelchair rides on the protrusion of the hinge or slope plate before riding on the rotation shaft of the hinge, and rides on the rotation shaft of the hinge while maintaining the state of riding on the protrusion. . In this way, since the wheel of the wheelchair rides on the hinge or slope plate protrusion and the rotation shaft portion of the hinge step by step, there is no protrusion on the hinge or slope plate, and compared with the aspect of riding the rotation shaft portion of the hinge at once. Thus, the wheel of the wheelchair can gently get over the rotating shaft of the hinge. For this reason, the wheelchair can be smoothly boarded.

  According to the slope structure of the present invention, it is possible to smoothly ride a wheelchair.

As shown in FIGS. 1 to 4, the vehicle 1 is a route bus that employs a slope structure that assists the getting on and off of a wheelchair with respect to the entrance 30 in the vicinity of the entrance 30 at the approximate center in the front-rear direction. The vehicle 1 includes a frame 3 that is fitted and fixed to a floor plate 2 that is notched in a channel shape toward the outside of the vehicle, a receiving plate 4 that is fixed to the frame 3, and a bridge surface 4 that extends from the receiving plate 4. A slope plate 5 having a boarding / alighting surface 5a to be transferred, a hinge 6 for rotatably connecting the receiving plate 4 and one end of the slope plate 5 are provided. The upper surface 4b of the receiving plate 4 and the upper surface 2a of the floor plate 2 constitute the floor surface 31 of the vehicle 1. The frame body 3 is made of metal or the like, and extends to the left and right on the front side of the entrance 30 and the front frame 7 A middle frame 8 that bends from the inner end of the vehicle and extends rearward, and a rear frame 9 that bends from the rear end of the middle frame 8 to the outer side of the vehicle and extends parallel to the front frame 7 are integrally formed. The front frame 7 has a front inclined surface 7a that is inclined downward from the front toward the rear. The middle frame 8 has a middle inclined surface 8a that slopes downward from the vehicle inner side toward the vehicle outer side. The rear frame 9 has a rear inclined surface 9a that is inclined downward from the rear toward the front. Each inclined surface 7 a, 8 a, 9 a constitutes a slope between the floor plate 2 and the receiving plate 4.

  The receiving plate 4 is composed of a plurality of long plates extending in the front-rear direction arranged in the left-right direction, and has a rectangular shape surrounded by the frame body 3. The plurality of elongated plates constituting the receiving plate 4 are between a channel-type main frame 10 extending in the front-rear direction and a square tube 11 extending in the front-rear direction at the left end of the vehicle 1, and are spaced apart in the front-rear direction. It arrange | positions on the several L-shaped angle 12 extended in the left-right direction at intervals. The receiving plate 4 is set to be lower than the floor plate 2 by the thickness of the slope plate 5 in consideration of storing the slope plate 5. Such a receiving plate 4 constitutes a floor surface 31 when the slope plate 5 is used (when deployed), and faces the entrance / exit surface 5a of the slope plate 5 when the slope plate 5 is stored.

  Between the front end portion of the receiving plate 4 and the front frame 7 and between the rear end portion of the receiving plate 4 and the rear frame 9, a pair of front and rear grooves 4a each extending linearly in the left-right direction is formed. ing. When the slope plate 5 is stored, a fall prevention wall 5c, which will be described later, of the slope plate 5 is inserted into the front and rear grooves 4a.

  The slope plate 5 can be set at a deployment position (position shown in FIG. 1) and a storage position (position shown in FIG. 3). The slope plate 5 in the unfolded position extends from the entrance / exit 30 to the outside of the passenger compartment and is bridged on the road surface 32, so that the entrance / exit surface 5a is exposed upward. The slope plate 5 in the retracted position is inverted from the deployed position around the rotation shaft 13a of the hinge 6 and is accommodated on the vehicle interior side of the entrance / exit 30 and faces the upper surface 4b of the receiving plate 4 with the entrance / exit surface 5a facing downward. To do. The slope plate 5 is composed of a plurality of elongated plates arranged in the left-right direction and extending in the front-rear direction, and has a rectangular shape that overlaps the receiving plate 4 and is surrounded by the frame 3 at the storage position. One surface (upper surface at the unfolded position) of the slope plate 5 constitutes a boarding / alighting surface 5a, and the other surface (lower surface at the unfolded position) 5b is continuous in substantially the same plane as the upper surface 2a of the floor plate 2 at the retracted position. To do. Further, the slope plate 5 has a pair of front and rear fall prevention walls 5c that stand up from both sides of the front and rear surfaces 5a and extend in the left-right direction. The front and rear fall prevention walls 5 c prevent the wheelchair from falling from the slope plate 5. The slope plate 5 is rotatably connected to the vehicle 1 by a hinge 6, is unfolded when used, is bridged from the floor surface 31 to the road surface 32, is folded when stored, and overlaps the receiving plate 4 from above.

  The hinge 6 is a floor surface coupling portion that is fixed to substantially the entire region of the rotating shaft portion 13 extending in the opening width direction of the entrance / exit 30 on the vehicle interior side of the entrance / exit 30 and the outer edge portion of the receiving plate 4 in the vehicle width direction. 14 and a slope plate connecting portion 15 fixed to substantially the entire region of one end edge of the slope plate 5.

  The rotating shaft portion 13 is a cylindrical body in which a shaft insertion hole (reference numeral omitted) is formed, and the rotating shaft 13a serving as the rotation center is inserted through the rotating shaft portion 13. The floor surface connecting portion 14 and the slope plate connecting portion 15 are integrally formed with the rotating shaft portion 13 at equal intervals, and the rotating shaft portion 13 integrally formed with the floor surface connecting portion 14 and the slope plate connecting portion 15 are integrated. The formed rotating shaft portions 13 are arranged alternately in the opening width direction. The floor surface connection portion 14 and the slope plate connection portion 15 are rotatably connected by the rotation shaft 13 a being inserted through the shaft insertion hole of the rotation shaft portion 13. As a result, the hinge 6 connects the receiving plate 4 and one end of the slope plate 5 so as to be rotatable about the rotation shaft 13 a of the rotation shaft portion 13.

  The rotation shaft portion 13 is provided between the boarding / alighting surface 5a of the slope plate 5 and the upper surface 4b of the receiving plate 4, and protrudes upward with respect to the boarding / alighting surface 5a of the slope plate 5 at the unfolded position. The upper end of the rotating shaft portion 13 is set at substantially the same height as the upper surface 4 b of the receiving plate 4.

  The slope plate connecting portion 15 extends from the rotary shaft portion 13 toward the slope plate 5, and a tip portion thereof is fixed to the slope plate 5. The upper surface of the slope plate connecting portion 15 and the upper surface of the floor surface connecting portion 14 cause the boarding surface 5a of the slope plate 5 and the upper surface 4b of the receiving plate 4 at the development position to be continuous via the rotary shaft portion 13.

  On the upper surface of the slope plate connecting portion 15, two left and right ridges 15a and 15b are formed so that the wheel WH of the wheelchair rides on and off the wheelchair. The two ridges 15a and 15b are arranged over substantially the entire area in the front-rear direction of the slope plate connecting portion 15, and are separated in the left-right direction and extend linearly in the front-rear direction. That is, in the slope unfolded state in which the slope plate 5 is set at the unfolded position, the boarding / alighting surface 5a, the ridge (first ridge) 15a, the ridge (second ridge) 15b, and the rotary shaft portion 13 are in this order. Line up from the outside in the vehicle width direction (outside the vehicle) to the inside in the vehicle width direction (inside the vehicle). The protrusion height Hp1 of the first protrusion 15a, the protrusion height Hp2 of the second protrusion 15b, and the protrusion height Hh of the rotary shaft portion 13 are set so that Hp1 <Hp2 <Hh. .

  In this way, the protrusions 15a and 15b extend in the opening width direction (front-rear direction) between the rotating shaft portion 13 and the getting-on / off surface 5a, protrude below the rotating shaft portion 13 with respect to the getting-on / off surface 5a, and get on / off The level difference with respect to the surface 5 a is reduced as compared with the rotation shaft portion 13.

  The ridges 15a and 15b are formed at positions where the wheelchair wheels WH can ride on the rotary shaft portion 13 while maintaining the state in which the wheel WH of the wheelchair rides on the ridges 15a and 15b when the wheelchair gets on and off the vehicle.

  On the upper surface of the floor surface connecting portion 14, recesses 14a and 14b are formed in which the ridges 15a and 15b of the slope plate connecting portion 15 are accommodated when the slope plate 5 is stored. 4 is set lower than the upper surface 4b of 4 and the upper end of the rotating shaft portion 13.

  Next, the case where the wheelchair on the road surface 32 gets into the vehicle 1 from the entrance 30 will be described. Before the wheelchair gets on, the slope plate 5 (see FIG. 3) in the storage position in the frame 3 is rotated to the unfolded position, and the boarding / alighting surface 5a is bridged from the floor surface 31 to the road surface 32 (see FIG. 1).

  The wheel WH of the wheelchair that has started boarding proceeds from the road surface 32 to the boarding / alighting surface 5a of the slope plate 5 and goes up the boarding / alighting surface 5a. The wheel WH that has reached the upper surface of the slope plate connecting portion 15 sequentially rides on the ridges 15a and 15b. The wheel WH riding on the ridges 15a and 15b rides on the rotating shaft 13 while maintaining the state. The wheel WH riding on the rotating shaft portion 13 gets over the ridges 15a and 15b, further gets over the rotating shaft portion 13, reaches the upper surface 4b (floor surface 31) of the receiving plate 4, and the middle inclined surface of the middle frame 8 Go up 8 a and reach the upper surface 2 a of the floor board 2.

  When the boarding of the wheelchair is completed, the slope plate 5 (see FIG. 1) in the unfolded position is rotated to return to the storage position in the frame 3 (see FIG. 3).

  As described above, in this embodiment, the wheel WH of the wheelchair when riding gets on the ridges 15a and 15b of the slope plate connecting portion 15 before getting on the rotating shaft portion 13, and gets on the ridges 15a and 15b. Riding on the rotating shaft portion 13 of the hinge 6 while maintaining the state. Thus, since the wheel WH climbs stepwise from the ridges 15a, 15b to the rotating shaft portion 13, the wheels WH are compared with the mode in which the ridges 15a, 15b do not exist and ride on the rotating shaft portion 13 at once. The rotating shaft 13 can be gently climbed over. For this reason, the wheelchair can be smoothly boarded.

  Moreover, since the two protrusions 15a and 15b whose height with respect to the entrance / exit surface 5a sequentially increases toward the rotating shaft portion 13 are provided, it is possible to more smoothly carry the wheel WH on the rotating shaft portion 13. it can.

  In the above-described embodiment, the case where the ridges 15 a and 15 b are formed on the slope plate connecting portion 15 constituting the hinge 6 has been described as an example. However, the step with respect to the landing surface 5 a can be reduced more than the rotating shaft portion 13. If possible, a protrusion may be formed at one end of the entrance / exit surface 5a on the hinge 6 side.

  Further, the number of protrusions is not limited to two, and may be one or three or more.

  As mentioned above, although the embodiment to which the invention made by the present inventor is applied has been described, the present invention is not limited by the discussion and the drawings that form part of the disclosure of the present invention according to this embodiment. That is, it should be added that other embodiments, examples, operation techniques, and the like made by those skilled in the art based on this embodiment are all included in the scope of the present invention.

  The slope structure according to the present invention can be used for a route bus and other vehicles.
