JP 2000-166971 A

  In the above-described conventional configuration, it is assumed that the fall preventing walls are erected on both sides of the slope plate to prevent the wheelchair from falling. In this case, the floor surface is formed with a wall receiving groove into which the fall preventing wall is inserted when the slope plate is stored. However, it is conceivable that foreign matter such as pebbles intrude into the wall receiving groove on the floor surface, in which case the anti-falling wall can not be inserted into the wall receiving groove. Therefore, the slope plate can not be stored reliably.

  Therefore, an object of the present invention is to provide a slope structure capable of reliably storing the slope plate even when the slope plate is provided with a fall prevention wall.

  In order to achieve the above object, the slope structure of the first aspect of the present invention is a slope structure that assists getting in and out of a wheelchair with respect to the entrance of a vehicle, and includes a floor surface of the vehicle, a slope plate and a hinge. The slope plate has a boarding surface. The hinge rotatably connects the floor surface and the slope plate about a rotation axis extending in the opening width direction of the entrance on the vehicle cabin side of the entrance.

  The slope plate extends from the entrance to the outside of the passenger compartment and is bridged to the road surface, and is accommodated at the deployed position where the entry / exit surface is exposed upwards and inverted from the deployed position around the rotation axis The storage surface can be set to the storage position facing the floor surface facing downward and the falling edge of the landing surface of the slope plate is a fall for preventing the wheelchair from falling from the slope plate in the deployed position. A prevention wall is provided in a protruding manner. The floor surface is provided with a bottomed wall receiving groove into which the anti-falling wall of the slope plate which opens upward and tilts to the storage position is inserted from above. The lower portion of the wall receiving groove has an end-spreading shape in which the groove width widens downward.

  The slope structure of the second aspect of the present invention is the slope structure of the first aspect, wherein the tip of the fall preventing wall is tapered such that the wall width becomes thinner toward the tip.

  In the above configuration, when the slope plate is stored, the tip end portion of the fall prevention wall abuts against a foreign object such as a pebble entering the wall receiving groove on the floor when the slope plate is stored. The tip of the fall preventing wall in contact with the foreign matter repels the foreign matter without sandwiching the foreign matter with the bottom of the wall accommodation groove.

  Since the wall receiving groove on the floor surface has a diverging shape in which the groove width widens downward, the foreign matter that is bounced off the tip of the fall preventing wall is retracted to the corner of the bottom of the wall receiving groove. Therefore, even if foreign matter such as pebbles intrude into the wall receiving groove on the floor, the fall preventing wall of the slope plate can be reliably inserted into the wall receiving groove on the floor. This allows the floor to be stacked on the floor without staggering during storage.

  According to the slope structure of the present invention, it is possible to reliably store the slope plate even in the case where the fall prevention wall is provided on the slope plate.

The middle frame 8 has a middle inclined surface 8 a that inclines downward from the inside to the outside of the vehicle. The rear frame 9 has a rear inclined surface 9 a that inclines downward from the rear to the front. Each slope 7 a, 8 a, 9 a constitutes a slope between the floor plate 2 and the receiving plate 4.

  The receiving plate 4 is formed of a plurality of elongated plates extending in the front-rear direction arranged in the left-right direction, and has a rectangular shape surrounded by the frame 3. The receiving plate 4 is set 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 (developing), and faces the landing surface 5 a 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, there are a pair of front and rear wall receiving grooves 41 extending linearly in the left-right direction. It is formed. The front and rear wall accommodation groove 41 is a bottomed groove which is opened upward and into which a fall preventing wall 5c described later of the slope plate 5 which tilts to the storage position is inserted from above. Each wall accommodation groove 41 has a U-shaped cross section including a pair of left and right wall portions 41a and a flat bottom portion 41b continuous to the lower ends of the left and right wall portions 41a. That is, each wall accommodation groove 41 is a U-shaped cross section in which the pair of wall portions 41a extend upward from both end edges of the bottom portion 41b. The lower part of each wall accommodation groove 41 has an end-spreading shape in which the distance between the pair of left and right wall parts 41a spreads toward the bottom part 41b. That is, the lower portion of each wall accommodation groove 41 has an end-spreading shape in which the distance between the left and right wall portions 41a, which is the groove width, widens downward. A fall prevention wall 5 c is inserted into each wall accommodation groove 41 when the slope plate 5 is stored.

  The slope plate 5 can be set at a deployed position (the position shown in FIG. 2) and a stored position (the position shown in FIG. 1). The slope plate 5 in the deployed position extends from the entrance 30 to the outside of the passenger compartment and is bridged to the road surface 32, and the entry / exit surface 5a is exposed upward. The slope plate 5 in the storage position is inverted from the unfolded position centering on the rotation axis (not shown) of the hinge 6 and is accommodated inside the passenger compartment of the entrance 30 with the landing surface 5a facing downward and the upper surface of the receiving plate 4 Face 4b. The slope plate 5 is formed of a plurality of elongated plates extending in the front-rear direction arranged in the left-right direction, and has a rectangular shape overlapping the receiving plate 4 at the storage position and surrounded by the frame 3. One surface (upper surface in the developed position) of the slope plate 5 constitutes a landing surface 5a, and the other surface (lower surface in the deployed position) 5b is continuous on the same plane as the upper surface 2a of the floor plate 2 at the storage position. Do.

  The slope plate 5 has a pair of front and rear anti-fall walls 5c that extend in the left-right direction from the front and rear sides of the landing surface 5a. That is, at the end edge portion of the landing surface 5 a of the slope plate 5, a pair of front and rear anti-fall walls 5 c are provided in a protruding manner. The front and rear anti-falling walls 5c have a plate shape extending linearly in a direction intersecting the rotation axis (not shown) of the hinge 6 and rising from the end edge portion of the landing surface 5a. Prevent wheelchair falls. The tip end portion of each falling prevention wall 5c has a tapered shape in which the wall width which is the thickness thereof becomes thinner toward the tip end (the lower end when the slope plate 5 is stored). The slope plate 5 is rotatably connected to the vehicle 1 by the hinge 6 and is deployed when in use, bridged from the floor surface 31 to the road surface 32, folded up during storage and overlapped with the receiving plate 4 from above. An embedded handle 5 d is provided substantially at the center of the other surface 5 b of the slope plate 5. The handle 5 d is used when the slope plate 5 is deployed.
