JP2013-162818A

  By the way, when a wheelchair or a caregiver rides on a vehicle slope such as that disclosed in Patent Document 1 spanned between the ground and the rear portion of the vehicle, a large force acts downward on the vehicle slope. As a result, the shock absorbing damper of the vehicle contracts and the vehicle side of the vehicle slope sinks greatly downward, and accordingly, a large force acting in the vehicle longitudinal direction acts on the vehicle slope. Therefore, when the wheelchair is repeatedly taken into and out of the vehicle accommodating portion, the force acting in the downward direction and the vehicle front-rear direction with respect to the vehicle slope is repeated, so that the protective cover is repeatedly deformed. A large force acts on the contact surface of the protective cover with the passage portion at one end edge of the passage in the passage direction on the back surface side, and there is a possibility that the protective cover may be cracked or torn starting from that portion. .

  This invention is made | formed in view of such a point, The place made into the objective is to provide the slope for vehicles which a protection cover does not break down easily even if it uses it repeatedly.

  In order to achieve the above object, the present invention is characterized in that the shape of the contact surface of the protective cover with the passage portion is devised.

  Specifically, it has a rectangular plate-like passage portion serving as a passage for a wheelchair, and the ground and the vehicle rear end in a posture in which one end side in the passage advancing direction of the passage portion faces the ground side and the other end side faces the vehicle side. The following solutions were taken for the slope of the vehicle that was installed in a straight line between the two to enable the wheelchair to get on and off.

  That is, in the first invention, a protective cover is provided that extends in the width direction of the passage and has a flexibility to cover one edge of the passage portion in the passage direction, and the contact surface of the protective cover with the passage portion includes: A groove is formed extending in the passage width direction and recessed toward the opposite passage portion side so as to avoid contact with a corner portion at one end edge in the passage traveling direction on the rear surface side of the passage portion.

  According to a second invention, in the first invention, the inner surface of the groove is located in the middle of the edge of the passage in the passage advancing direction of the passage in the cross section intersecting the passage width direction, and extends in the passage advancing direction. A first curved surface extending downward while curving so as to bulge to one side, and one end continuous to the other end of the first curved surface, and extending to the other side in the passage advancing direction while curving so as to bulge downward. The other end is constituted by a second curved surface connected to a position closer to one end of the passage portion rear surface in the passage advancing direction.

  In a third invention, in the first or second invention, the protective cover gradually has a dimension in the thickness direction of the passage portion as it goes from the position corresponding to one edge of the passage portion in the passage direction to the opposite passage portion side. In use, an inclined surface forming portion is provided that forms an inclined surface by eliminating a step between one edge of the passage portion in the passage advancing direction and the ground during use.

  According to a fourth aspect, in the third aspect, the tip of the inclined surface forming portion is provided with a flexible lip portion protruding toward the opposite passage portion side.

  According to a fifth invention, in the third or fourth invention, the protective cover gradually has a dimension in the thickness direction of the passage portion as it goes from the back surface side of the inclined surface forming portion to the other end side in the passage traveling direction. A long reinforcing support portion is provided, and the reinforcing support portion fills a space between the back surface of the passage portion and the ground in use and continuously contacts the ground together with the inclined surface forming portion.

  In the first aspect of the invention, even if a wheelchair or a caregiver gets on the vehicle slope, a large force acts on the protective cover downward and in the vehicle front-rear direction to deform the protective cover. The corner portion at one edge of the passage in the passage direction does not contact the protective cover by the groove. Therefore, it can prevent that the corner | angular part in the passage advancing direction one end edge of a channel | path part back side damages a protective cover, and a crack and a tear generate | occur | produce.

  In the second invention, even if a large force acts on the vehicle slope in the vehicle front-rear direction, the corner portion at one edge of the passage advancing direction on the rear surface side of the passage portion serves as the protective cover by the space formed by the first curved surface. Do not touch. On the other hand, even if a large force is applied downward to the vehicle slope, the corner portion at one edge of the passage traveling direction on the rear surface side of the passage portion does not contact the protective cover due to the space formed by the second curved surface. In this way, the protective cover is not damaged even if a large force is applied in any direction below or behind the vehicle, and it is possible to reliably prevent the protective cover from being cracked or torn.

  In the third aspect of the invention, when the vehicle slope is used, the wheelchair can smoothly ride on the vehicle slope due to the inclined surface, so that the burden on the caregiver when getting on and off the vehicle can be reduced.

  In the fourth aspect of the invention, when the vehicle slope is bridged between the ground and the rear end of the vehicle, the lip portion eliminates a step along the ground even when the ground is uneven. This can be done without choosing where to get on and off the wheelchair.

  In 5th invention, when using the slope for vehicles, not only the lower surface of the inclined surface formation part located in an anti-passage part side rather than the position corresponding to the passage advancing direction one end edge of the passage part in a protection cover, but a passage part Since the lower surface of the reinforcing support portion located on the side of the passage portion from the position corresponding to one edge of the passage in the passage direction also contacts the ground, a wide contact area with the ground of the protective cover is secured, and the wheelchair rides on the vehicle slope. When this happens, the load applied to the protective cover is dispersed. Therefore, even if the corner portion at one edge of the passage traveling direction on the back surface side of the passage portion comes into contact with the protective cover, the force transmitted from the corner portion to the protective cover is reduced, and it is possible to reliably prevent the occurrence of cracks and tears. it can.

It is a perspective view of the vehicle rear part which shows the state which spanned the vehicle slope which concerns on embodiment of this invention between the vehicle rear end and the ground. It is sectional drawing in the AA of FIG. FIG. 3 is a view corresponding to FIG. 2 in a state where the wheelchair and the caregiver are in the middle of the vehicle slope spanned between the ground and the rear end of the vehicle.

  FIG. 1 shows a wheelchair-accessible vehicle 10 in a state where a vehicle slope 1 according to an embodiment of the present invention is bridged between a vehicle rear end and a ground G. In the vehicle interior on the rear side of the wheelchair-accommodating vehicle 10, an accommodating portion 10 a capable of accommodating the wheelchair 5 on which a cared person or the like (not shown) is seated is provided, at the rear end of the roof R of the wheelchair-accommodating vehicle 10. The back door 10b is attached so that it can be opened and closed up and down. A tail gate 10c and the vehicle slope 1 are respectively attached to the rear end of the floor F forming the floor of the housing portion 10a so as to be rotatable up and down.

  The vehicle slope 1 has a rectangular plate shape obtained by extrusion molding, and includes a single-plate aluminum alloy plate member 2 (passage portion) serving as a passage for the wheelchair 5 and both side edge portions of the plate member 2. And a pair of resin-made anti-wheel removal prevention plates 3 attached along the longitudinal direction thereof, and when not in use, are stored inside the vehicle 10 so as to rotate upward and extend vertically. In use, the back door 10b is opened upward, and the tailgate 10c and the vehicle slope 1 are rotated downward so that one end side in the passage advancing direction of the plate member 2 is on the ground G side, and The wheelchair 5 is allowed to get on and off in a straight line between the rear end of the vehicle 10 and the ground G with the other end side facing the vehicle 10 side.

  A rubber protective cover 4 having flexibility is attached to one end edge of the plate member 2 in the passage traveling direction, and the protective cover 4 has a substantially U-shaped cross section extending in the passage width direction as shown in FIGS. It has a letter shape and covers one edge of the plate member 2 in the passage direction.

  The protective cover 4 includes an inclined surface forming portion 4a located on the side opposite to the plate member 2 from a position corresponding to one edge of the plate member 2 in the passage direction, and a passage from the back surface side of the plate member 2 of the inclined surface forming portion 4a. Reinforcing support portion 4b extending to the other edge side in the traveling direction and positioned on the back surface side of the plate member 2, and extending from the surface side of the plate member 2 of the inclined surface forming portion 4a to the other end side in the passage traveling direction. The surface side extension part 4c located in the surface side of this, and the back surface side extension part 4d extended from the said reinforcement support part 4b to a path | route advancing direction other end side are provided.

  The inclined surface forming portion 4a has a substantially triangular cross-section in which the dimension in the thickness direction of the plate member 2 gradually decreases toward the opposite plate member 2 side. The inclined surface 4f is formed without a step with the ground G.

  At the tip of the inclined surface forming portion 4a, a flexible lip portion 42 is provided on the side opposite to the plate member 2 and obliquely below the back side of the plate member 2 (see the phantom line in FIG. 2). When using the slope 1 for vehicles, it deform | transforms into the surface side of the said plate member 2, and follows the ground G.

  The reinforcing support portion 4b has a shape in which the dimension in the thickness direction of the plate member 2 gradually increases from the back surface side of the plate member 2 of the inclined surface forming portion 4a toward the other end side in the passage traveling direction. The space between the back surface of the plate member 2 and the ground G is filled. That is, the reinforcing support portion 4b comes into continuous contact with the ground G together with the inclined surface forming portion 4a when the vehicle slope 1 is bridged between the ground G and the rear end of the vehicle 10. Yes.

  The surface-side extending portion 4c has a thin plate shape and is located on the opposite side of the reinforcing support portion 4b with the plate member 2 interposed therebetween. As it goes to the other end side in the traveling direction, it is gradually curved so as to be positioned on the plate member 2 side.

  Moreover, the said back surface side extension part 4d is following the passage advancing direction other end side of the said reinforcement support part 4b, and the dimension of the thickness direction of the plate member 2 becomes short gradually as it goes to the other end side of a passage advancing direction. It has a shape.

  The contact surface 4e of the protective cover 4 with the plate member 2 is substantially in cross section formed by the inclined surface forming portion 4a, the reinforcing support portion 4b, the front surface side extending portion 4c, and the back surface side extending portion 4d. The U-shaped portion of the contact surface 4e corresponding to the corner portion 2b at the edge of the passage in the passage direction on the back surface side of the plate member 2 extends in the passage width direction and is recessed toward the opposite plate member 2 side. A concave groove 41 that avoids contact with the corner 2b is formed.

  The inner surface of the concave groove 41 is in a cross section intersecting with the passage width direction, and is bent while curving so that one end is located in the middle of the edge of the passage direction of the plate member 2 and bulges to one side of the passage direction. A first curved surface 41a extending to the other side, one end of which is continuous with the other end of the first curved surface 41a, and is curved so as to swell downward while extending to the other side in the passage advancing direction and the other end is the back surface of the plate member 2 It is comprised with the 2nd curved surface 41b connected to the position near one end of the passage advancing direction. That is, the cross-sectional shape of the concave groove 41 has a fan shape with a central angle of about 270 degrees. The cross-sectional shape of the concave groove 41 may be a fan shape having a central angle other than 270 degrees.

  Next, a description will be given of a case where a vehicle slope is bridged between the ground G and the rear end of the vehicle 10 to ride the wheelchair 5 on the vehicle 10.

  First, a caregiver (not shown) rotates the back door 10b of the vehicle 10 upward and the tailgate 10c downward to open the accommodating portion 10a to the rear of the vehicle.

  Next, the vehicle slope 1 stored inside the vehicle 10 is rotated downward, and the vehicle slope 1 is bridged between the ground G and the rear end of the vehicle 10 as shown in FIG. Then, as shown in FIG. 2, the lower surface of the inclined surface forming portion 4 a of the protective cover 4 and the lower surface of the reinforcing support portion 4 b are continuously in contact with the ground G, and the lip portion 42 is deformed upward along the ground G. .

  Next, the caregiver pushes the wheelchair 5 on which the cared person rides and places the wheelchair 5 on the vehicle slope 1. Then, as shown in FIG. 3, a large force acts downward (X1 direction) on the vehicle slope 1, and the vehicle 10 greatly sinks downward by the shock absorbing damper, and accordingly, the vehicle slope 1. The other end side in the passage advancing direction greatly sinks downward, and the plate member 2 tends to move to one side (X2 direction) in the passage advancing direction. Then, the protective cover 4 is pushed by the plate member 2 to one side in the passage advancing direction, and the inclined surface forming portion 4a in the protective cover 4 is slanted around the corner 2a at one end edge in the passage advancing direction on the surface side of the plate member 2. It is deformed while rotating upward (Y1 direction) so that the surface corresponding to one end edge of the plate member 2 in the passage direction of the plate member 2 on the contact surface 4e of the groove 41 is separated from one end edge of the plate member 2 in the passage direction. Deform. At this time, the plate member 2 moves downward and in the front-rear direction of the vehicle 10, but the corner portion 2 b at one edge of the passage direction of the plate member 2 on the back surface side is formed on the contact surface 4 e of the protective cover 4 by the concave groove 41. Do not touch.

  Thereafter, the caregiver accommodates the wheelchair 5 in the accommodating portion 10a, rotates the tailgate 10c of the vehicle 10 upward and the back door 10b downward, and the boarding of the wheelchair 5 is completed.

  Note that the state of the protective cover 4 when the wheelchair 5 is dismounted with the vehicle slope 1 is substantially the same as the state of the protective cover 4 when the wheelchair 5 is loaded with the vehicle slope 1 described above. The detailed explanation is omitted.

  As described above, when the wheelchair 5 is repeatedly put on and off the vehicle 10 using the vehicle slope 1, the deformation of the protective cover 4 is repeated, but in the case of the vehicle slope 1 according to the embodiment of the present invention. When the wheelchair 5 or a caregiver (not shown) rides on the vehicle slope 1, a large force acts on the protective cover 4 from the plate member 2 downward and in the front-rear direction of the vehicle 10 to deform the protective cover 4. In addition, the corner portion 2 b at one end edge of the plate member 2 on the back surface side in the passage traveling direction does not contact the protective cover 4 by the concave groove 41. Therefore, it can prevent that the corner | angular part 2b in the path | route advancing direction one end edge of the back surface side of the plate member 2 damages the protective cover 4, and causes a crack and a tear.

  Further, even if a large force acts on the vehicle slope 1 in the longitudinal direction of the vehicle 10, the corner portion 2b at the one end edge in the passage traveling direction on the rear surface side of the plate member 2 is protected by the space formed by the first curved surface 41a. 4 is not touched. On the other hand, even if a large force is applied downward to the vehicle slope 1, the corner 2 b at the one end edge in the passage traveling direction on the back surface side of the plate member 2 contacts the protective cover 4 due to the space formed by the second curved surface 41 b. do not do. In this way, the protective cover 4 is not damaged even if a large force acts in the downward direction or the vehicle rear direction, and it is possible to reliably prevent the protective cover 4 from being cracked or torn.

  Further, the inclined surface 4f of the inclined surface forming portion 4a allows the wheelchair 5 to smoothly ride on the vehicle slope 1 when the vehicle slope 1 is used. Can be reduced.

  In addition, when the vehicle slope 1 is bridged between the ground G and the rear end of the vehicle 10, the lip portion 42 eliminates the step along the ground G even if the ground is rough, so that the vehicle of the wheelchair 5 10 can be carried out without choosing the place of getting on and off of the wheelchair 5.

  And when using the slope 1 for vehicles, not only the lower surface of the inclined surface formation part 4a located in the anti-plate member 2 side rather than the position corresponding to the passage advancing direction one end edge of the plate member 2 in the protective cover 4, but plate Since the lower surface of the reinforcing support part 4b located on the plate member 2 side also contacts the ground G rather than the position corresponding to one edge of the passage direction of the member 2, the contact area of the protective cover 4 with the ground G is widely secured. The load applied to the protective cover 4 when the wheelchair 5 is on the vehicle slope 1 is dispersed. Therefore, even if the corner portion 2b at one edge of the passage direction of the plate member 2 on the back surface side contacts the protective cover 4, the force transmitted from the corner portion 2b to the protective cover 4 is reduced, and cracks and tears are generated. It can be surely prevented.

  The vehicle slope 1 according to the embodiment of the present invention can be switched between a storage state in the vehicle 10 and a state in which the vehicle slope 1 is bridged between the rear end of the vehicle 10 and the ground G by rotating. For example, it may be a detachable vehicle slope 1 that is not connected to the vehicle 10 and is bridged between the rear end of the vehicle 10 and the ground G when the wheelchair 5 is moved on and off.

  In the embodiment of the present invention, the material of the protective cover 4 is a rubber material. However, other materials may be used as long as they have flexibility, for example, a resin material may be used. .

  Furthermore, in the embodiment of the present invention, the cross-sectional shape of the groove 41 is a fan shape, but is not limited thereto, and any cross-sectional shape that can avoid contact with the corner 2b may be used.

  In addition, in the embodiment of the present invention, the vehicle slope 1 is composed of a single plate. However, the present invention is not limited to this, and for example, the vehicle slope 1 can be compacted by folding or sliding. Is also applicable.

  And although the said plate member 2 applies what was obtained by extrusion molding, you may apply not only this but the thing obtained by cut | disconnecting a board | plate material to a predetermined magnitude | size.

  The present invention is suitable for a vehicle slope used when a wheelchair is accommodated inside a vehicle.
