According to the slope plate device installed in the vehicle of the present invention, the operator pulls the slope plate out of the storage position to the outside through the opening of the slope plate storage portion, and rotates downward around the base portion. The tip is grounded to the use position, and the slope plate in the use position is turned upward to move the tip away from the ground to a substantially horizontal state. In this substantially horizontal state, the slope plate Push it into the storage position through the opening of the storage unit. When the slope plate at the use position is rotated upward, the elastic force of the elastic member is applied. Therefore, the force required for the upward rotation operation is downward based on the weight of the slope plate. Therefore, it is possible to reduce the operator's burden by subtracting the elastic force of the elastic member from the rotational force. Since the elastic force of the elastic member is smaller than the downward turning force based on the weight of the slope plate, the downward rotation based on the weight of the slope plate is obstructed when the slope plate is set to the use position. Can do without.

One end portions of 8A and 8B are provided to be freely engageable. The elastic members 8A and 8B resist the downward rotation force based on their own weight with the base portion of the slope plate 4 (the rotation center of the roller member 4C) as the center, with one end engaged with the engaging members 9A and 9B. Thus, an elastic force is applied to the slope plate 4, and this elastic force is made smaller than the downward turning force based on the weight of the slope plate 4. Further, as shown in FIG. 4, the elastic members 8A and 8B are provided in a shape in which one end is slightly bent downward, and when the slope plate 4 is pulled out to a substantially horizontal state, the one end is engaged with the engaging members 9A and 9B. It is easy to engage with.
[0014]
Next, the operation of this configuration will be described.
1 to 3, in the slope plate 4, each roller member 4C comes into contact with each stop member 6B, rotates downward about the rotation center of each roller member 4C, and grounds the tip side to the ground 5, and gets on and off. Between the floor surface 3 of the mouth 2 and the ground surface 5, it is located at a use position held in an inclined state. The auxiliary plate 7 pivots downward by its own weight with the base portion as the center, and the tip portion contacts the upper surface 4A on which the passenger of the slope plate 4 gets on and off, and exists between the slope plate 4 and the floor surface 3 of the entrance / exit portion 2 It is located in the 1st position which block | closes the clearance gap H. As a result, passengers using wheelchairs such as disabled persons can easily get on and off. At this time, one end of the elastic members 8A and 8B engages with the engaging members 9A and 9B, and an elastic force smaller than the rotational force against the downward rotational force based on the weight of the slope plate 4 is applied to the slope plate 4. Has been granted. Each roller member 7B on the lower surface of the auxiliary plate 7 is detached from the upper surface 4A of the slope plate, and the opening / closing lid 6C rotates downward about the hinge 6D to open the opening.
[0015]
1 to 3 in which the slope plate 4 is in the use position, when passengers get on and off, an operator such as a bus driver hangs both hands on the outside of both ends in the width direction on the tip side of the slope plate 4, and the slope The plate 4 is pivoted upward to bring it into a substantially horizontal state as shown in FIG. 5, and in this substantially horizontal state, the slope plate 4 is pushed into the inside through the opening of the slope plate housing portion 6 as shown in FIG. When the slope plate 4 is pushed inside, each roller member 4C of the slope plate 4 rotates along each rail member 6A, and each roller member 7B of the auxiliary plate 7 comes into contact with the slope plate upper surface 4A. Since the upper surface 4A of the slope plate rotates, the slope plate 4 can be pushed in smoothly. One end of the elastic members 8A and 8B comes out of the engaging members 9A and 9B as the slope plate 4 is pushed in to release the engagement with the engaging members 9A and 9B. When the slope plate 4 is pushed into the storage position, each roller member 7B comes into contact with each cam member 4D and pushes the auxiliary plate 7 upward to the second position, and the auxiliary plate 7 is flush with the upper plate 3A. Then, the opening / closing lid 6 </ b> C is rotated upward to close the opening of the slope plate storage 6.
[0016]
In order to set the slope plate 4 in the storage position to the use position, the opening / closing lid 6C is pivoted downward to open the opening of the slope plate storage unit 6, and the operator substantially opens the slope plate 4 to the outside through the opening. When pulled out horizontally, the state shown in FIG. 5 passes through the state shown in FIG. 6 contrary to the above, and in the state shown in FIG. 5, one end of the elastic members 8A and 8B enters the engaging members 9A and 9B. The auxiliary plate 7 engages with the combined members 9A and 9B, and each roller member 7B is detached from the upper surface 4A of the slope plate. Then, the operator turns the slope plate 4 downward and grounds the tip side to the ground 5 to be in a use position. At this time, the elastic force of the elastic members 8A and 8B is based on the own weight of the slope plate 4. Since it is smaller than the downward turning force, it is possible to prevent the slope plate 4 from rotating downward based on its own weight.
[0017]
With this operation, when the operator rotates the slope plate 4 in the use position upward, the elastic force of the elastic members 8A and 8B is applied, so the force required for the upward rotation operation is Further, it is possible to reduce the slope of the slope plate 4 by subtracting the elastic force of the elastic members 8A and 8B from the downward rotational force based on the weight of the slope plate 4, and the burden on the operator can be reduced. Further, the elastic members 8A and 8B are attached to the slope plate lower surface 4E, and the engaging members 9A and 9B engaged with one end portion of the elastic member 8A and 8B extending to the slope plate storage portion 6 are opposed to the slope plate lower surface 4E. Since it is provided on the bottom surface 6E of the slope plate storage portion 6, it is not necessary to add a member to the slope plate upper surface 4A side on which passengers get on and off, and it is possible to prevent getting in and out.
[0018]
7 and 8 show a modification of the elastic member. In the case of FIG. 7, two elastic members 81A and 81B formed in a substantially L shape are provided, and in the case of FIG. 8, they are formed in a substantially T shape. A single elastic member 82 is provided. These elastic members 81A, 81B, 82 are formed by bending a wire of a piano wire in the same manner as the elastic members 8A, 8B of one embodiment, or are made of spring steel materials defined in Japanese Industrial Standard G4801 (revised in 1977). The wire may be formed by bending, may be in another shape, may be flat steel instead of the wire, and can be appropriately implemented with a material having elasticity.
[0019]
In one embodiment of the present invention, the auxiliary plate 7 that cuts off a part of the upper plate 3A and closes the gap H existing between the slope plate 4 and the floor surface 3 of the entrance / exit portion 2 is provided. For example, as shown in Utility Model Registration No. 2513397, an auxiliary lamp board having a base screwed to the upper surface of one end of a lamp board (corresponding to the slope plate 4 of one embodiment) is not limited thereto. Of course, it may be provided as needed, and is of course not necessarily required.
[0020]
【The invention's effect】
As described above, in the first aspect of the present invention, the elastic member that imparts an elastic force smaller than the rotational force to the slope plate against the downward rotational force based on the weight of the slope plate is provided between the slope plate and the slope plate storage portion. When the slope plate at the use position is rotated upward, the elastic force of the elastic member is applied, and the force required for the upward rotation operation is the weight of the slope plate. Therefore, it is possible to reduce the operator's burden by subtracting the elastic force of the elastic member from the downward rotational force based on the above.
[0021]
Further, attaching a elastic member in a slope plate lower surface, because one end of the elastic member extending in the slope plate accommodating portion is provided on the bottom surface of the slope plate housing portion facing the slope plate lower surface of the engaging member to engage It is not necessary to add a member to the upper surface side of the slope plate on which passengers get on and off, and it can be done without hindering getting on and off.
