Description

  The present invention relates to a variable slope structure for a vehicle, for example, for getting on and off a vehicle such as a wheelchair on which a cared person is seated.

  2. Description of the Related Art In recent years, there are vehicles such as hybrid vehicles and electric vehicles that have a high opening ground height of a tailgate at the rear of a vehicle body by placing a battery under the floor of the vehicle. When a slope for a wheelchair is adopted for a vehicle having a high opening ground clearance, it is conceivable that an inclination angle of the slope increases when the slope is grounded.

  As a countermeasure against this, a variable slope is known in which the slope is divided into three main plates, a vehicle body side plate, and a ground side plate. Specifically, in the variable slope, the main plate body and the vehicle body side plate body are rotatably connected, and the main plate body and the ground side plate body are rotatably connected. Further, the vehicle body side plate body is rotatably connected to the vehicle body side. Further, the ground side plate is grounded to the road surface when the variable slope is used. (For example, refer to Patent Document 1).

  According to the variable slope of Patent Document 1, it is possible to rotate and bend the main plate body and the vehicle body side plate body or to rotate and bend the vehicle body side plate body and the ground side plate body when the variable slope is in use. . Therefore, the height of the main plate can be adjusted in a state where the inclination angle of the main plate is kept small. Thereby, the burden at the time of getting on and off a wheelchair using a variable slope can be reduced.

Here, the variable slope of Patent Document 1 is configured to bend the main plate body and the vehicle body side plate body, bend the main plate body and the ground side plate body, and adjust the height of the main plate body. Thus, for example, when a cared person seated in a wheelchair gets on the vehicle, the main plate and the ground-side plate are bent into a convex shape in a state where the wheelchair has moved from the ground-side plate to the main plate. That is, the inclination angle of the ground side plate body with respect to the main plate body is increased.
For this reason, the practical use of the structure which the wheelchair which moved to the main plate body does not reverse | retreat to the ground side plate body side is calculated | required.

The second inclined portion 44 extends downward from one end 43a of the flat portion 43 toward the main plate body 26 in a state where the main plate body 26 is disposed at the low position P1.
In other words, in a state where the main plate body 26 is disposed at the low position P1, the second inclined portion 44 is inclined and inclined upward from the main plate body 26 to the one end 43a of the flat portion 43 toward the ground side plate body 27. In this state, the second inclined portion 44 is disposed on the main plate body 26 side.

  A resin portion 45 is provided at one end 44 a of the second inclined portion 44. In a state where the main plate body 26 is disposed at the low position P1, the resin portion 45 contacts the main plate body 26. Here, the left reverse prevention means 28 is formed in a substantially trapezoidal shape in a side view by the attachment portion 41, the first inclined portion 42, the flat portion 43, the second inclined portion 44, and the resin portion 45.

Therefore, in the state where the wheelchair 21 rides on the flat portion 43, the cared person 23 (see FIG. 7) and the weight F <b> 1 of the wheelchair 21 are supported by the first inclined portion 42 and the second inclined portion 44.
As a result, when the wheelchair 21 is moved from the ground side plate 27 to the main plate 26, the left wheel (specifically, tire) 36 of the wheelchair 21 can be moved on the left retreat prevention means 28 and moved. A wheel (specifically, a tire) 37 can ride on the right reverse prevention means 29 and move.

  Further, in the state where the end 44 of the left backward prevention means 28 is formed in the second inclined portion 44 and the main plate body 26 is disposed at the low position P1, the second inclined portion 44 is changed from the main plate body 26 to the ground side plate body 27. It is inclined to the upward slope. In other words, the second inclined portion 44 is inclined downwardly from the main plate body 26 toward the ground side plate body 27.

Therefore, when the left wheel 36 of the wheelchair 21 rides on the left reverse prevention means 28 from the ground side plate 27, the left wheel 36 is caught on the end portion (that is, the second inclined portion) 44 of the left reverse prevention means 28. Can be prevented. As a result, it is possible to prevent the left wheel 36 from being obstructed at the end 44 of the left reverse prevention means 28.
Accordingly, the left wheel 36 can be smoothly moved along the left retreat prevention unit 28 after the wheelchair 21 is mounted on the left retreat prevention unit 28 from the ground side plate 27.

  Further, since the end 44 of the left backward prevention means 28 is formed in the second inclined portion 44, when the left wheel 36 of the wheelchair 21 rides on the left backward prevention means 28 from the main plate body 26, the second inclined portion 44. It is possible to smoothly ride on the left backward prevention means 28 via the above. Thereby, the left wheel 36 can be smoothly moved along the left reverse prevention means 28.

As shown in FIGS. 5 and 6, in the state where the main plate 26 is disposed at the high position P <b> 2, the inclination angle θ <b> 2 of the ground side plate 27 is larger than the inclination angle θ <b> 1 of the main plate 26. Therefore, the main plate 26 and the ground side plate 27 are arranged in a bent state so as to protrude upward.
A mounting portion 41 of the left reverse prevention means 28 is attached to the base end portion 27 a of the ground side plate body 27.

When the main plate 26 and the ground side plate 27 protrude upward, the flat portion 43 of the left retreat prevention means 28 protrudes upward along the ground side plate 27 from the main plate 26 in an inclined manner. In this state, the second inclined portion 44 and the resin portion 45 protrude from the one end 43a of the flat portion 43 toward the front side of the vehicle body.
Accordingly, the second inclined portion 44 and the resin portion 45 are arranged at a position protruding upward from the main plate body 26 together with the flat portion 43.

In this way, by using the bending of the main plate body 26 and the ground side plate body 27, the flat portion 43, the second inclined portion 44, and the resin portion 45 of the left receding prevention means 28 can be protruded upward from the main plate body 26. it can.
