DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope device for a vehicle for facilitating getting on and off with a wheelchair by, for example, hanging a slope plate between a floor surface and a road surface of a bus.

[0002]

2. Description of the Related Art Conventionally, there has been a vehicle such as a bus equipped with a slope device capable of hanging a slope plate between a floor surface and a road surface in order to facilitate getting on and off a wheelchair and the like. The slope device is usually stored under the floor and can be pulled out and used when needed.

[0003] Fig. 3 is a perspective view schematically showing a structure around the entrance of a bus equipped with a conventionally known slope device, and Fig. 4 is a schematic sectional view of the structure. 3 shows a state where the slope device is used, and FIG. 4 shows a state where the slope device is not used.

[0004] In FIGS. 3 and 4, this bus has a slope device 61 mounted below the floor surface 51 at the entrance. The slope device 61 is provided with an opening closed by an opening / closing cover 62 on an upright wall surface 53 between the floor surface 51 and the step 52, and is disposed so as to lie below the floor surface 51. The slope device 61 includes a housing 63 fixedly mounted on the vehicle frame 54 below the floor surface 51, and a bogie 64 moved in the front-rear direction in the housing 63. It is composed of a slope plate 65 that can be put in and taken out of the housing 63, a bridge plate 66 that connects the slope plate 65 and the floor surface 51, and the like.

More specifically, the bogie 64 has a pulley 67
The pulley 67 is configured so that the bogie 64 can smoothly move in the front-rear direction in the housing 63 by the rolling of the pulley 67. Further, a roller 68 is provided at the tip (drawer side) of the carriage 64 so as to protrude from the left and right directions.

The slope plate 65 has a coupling guide member 69 on the lower surface on the rear end (on the side of the carriage 64), and a roller 68 is hinged to the coupling guide member 69. The hinge connection between the connection guide member 69 and the roller 68 is performed by the carriage 64.
, And allows the slope plate 65 to move in the front-rear direction with respect to the carriage 64.

[0007] The transfer plate 66 is attached to the rear end of the slope plate 65 so as to be rotatable up and down via a hinge 70. And this passing plate 66 is a slope plate 65
A position (storage position) that is substantially in close contact with the top (storage position), and a position that is rotated by approximately 180 degrees from this storage position (pull-out position)
In addition, the structure is such that the rotation can be switched with the hinge 70 as a fulcrum.

Next, an operation using the slope device 61 configured as described above will be described. First, when the slope plate 65 is not used, as shown by a solid line in FIG. 4, the slope plate 65 is entirely pushed into the housing 63 together with the carriage 64, and the opening is closed by the opening / closing cover 62. It is in a state. And handover board 6
Numeral 6 is placed substantially in close contact on the slope plate 65 with the rotation tip side outside (opening portion side), and a part of the slope plate 65 overlaps the carriage 64 in the vertical direction.

On the other hand, when the slope plate 65 is used, the opening / closing cover 62 is first opened. Then, immediately inside the opening, the crew or the like pulls the tip of the slope plate 65 exposed in the opening outward (in the direction of the arrow 71 in FIG. 4) by hand. Then, the slope plate 65 is pulled out together with the carriage 64 to the outside. When the carriage 64 is pulled out to the position where the drawer is restricted, the carriage 6 is pulled out.
4 stops at that position, and only the slope plate 65
The amount that is overlapped with is further drawn. Then, when the slope plate 65 is pulled out to the final position indicated by the two-dot chain line in FIG. 4, the leading end of the slope plate 65 on the drawing side is displaced downward. Then, the entire slope plate 65 is rotated downward about the roller 68 as a fulcrum, and the slope plate 6
The turning tip of 5 is grounded on the road surface 72, and is in a state of being connected by the slope plate 65 inclined from the floor surface 51 to the road surface 72.

Next, the transfer plate 66 lying on the slope plate 65 is rotated rearward with the hinge 70 as a fulcrum, and the turning end of the transfer plate 66 is hooked on the floor surface 51. As a result, the handover plate 66 is bridged between the slope plate 65 and the floor surface 51, and a gap between the slope plate 65 and the floor surface 51 is eliminated, so that getting on and off a wheelchair or the like can be facilitated. The carriage 64, the slope plate 65, and the crossover plate 66, which are indicated by alternate long and short dash lines in FIGS. 3 and 4, show this use state. Next, when the slope plate 65 is stored, it can be stored in the storage position indicated by the solid line in FIG.

[0011]

However, in the above-described slope device having the conventional structure, when rotating the handover plate 66, a crew member or the like operates by hand. For this reason, the operation takes time, and the operation time of a bus or the like is lost.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a vehicle for which a transfer plate can be automatically moved to a use position and a non-use position in conjunction with insertion and removal of a slope plate. To provide a slope device.
Further, other objects will be clarified sequentially in the contents described below.

Means for Solving the Problems The present invention is characterized by taking the following technical means in order to achieve the above object.
That is, a slope plate that draws out from the underfloor storage part of the entrance and exit, grounds the tip thereof to the road surface, connects the floor surface of the entrance and exit with the road surface, and a bridge that closes a gap between the slope plate and the floor surface. A slope plate for a vehicle including a plate and a crossover plate rotatably attached to the other end side of the slope plate via a hinge, and a rotation tip side faces the drawing tip side of the slope plate on the slope plate. The slope plate is housed while being movably provided at a storage position where the slope plate is substantially in close contact with the storage position, and a drawer position where the hinge can be rotated to the opposite side so that the rotating tip side can be hooked on the floor surface. Between the housing and the handover plate,
The handover plate is moved from the storage position to the drawout position in conjunction with the pullout operation of the slope plate, and the handover plate is rotated from the drawout position to the storage position in conjunction with the pushing operation of the slope plate. And a movement control means that can perform the movement.

According to this, when the slope plate is pulled out,
In conjunction with this withdrawal operation, the handover plate is automatically rotated and moved from the storage position to the withdrawal position. Conversely, when the slope plate is stored, when the slope plate is pushed in, the handover plate is automatically rotated and moved from the pull-out position to the storage position in conjunction with the pushing operation. Therefore, the position of the handover plate is automatically switched in conjunction with the insertion / removal of the slope plate,
The crew need only perform the work of taking in and out the slope plate. As a result, the operation can be speeded up.

This makes it easy to get on and off a wheelchair or the like. Therefore, in this structure, the handover plate 6 is automatically rotated in conjunction with the operation of pulling out the slope plate 5, whereby the handover plate 6 is passed between the floor surface 51 and the slope plate 5 without using a hand. be able to.

Next, when the slope plate 5 is to be stored again, the slope plate 5 grounded on the road surface 72 is lifted to a substantially horizontal position, and is pushed inward of the housing 4. Then, the slope plate 5 is pushed together with the carriage 3, and as the pushing is carried out, the crossing plate 6 contacts the step edge material 55 with an arrow 34.
And rotates back to a position where it is superimposed on the slope plate 5 in close contact. Then, when the slope plate 5 is pushed together with the carriage 3 as it is, it can be pushed back to the initial position and stored in the housing 4,
When the cover 2 is closed thereafter, the storing operation ends. Therefore, in this structure, even when the slope plate 5 is pushed in and stored, the passing plate 6 is automatically rotated in the opposite direction in conjunction with the pushing operation, and the passing plate 6 can be stored without using a hand. it can.

In the above-described embodiment, the case where the present invention is applied to the entrance of a route bus has been described. However, the present invention is not limited to the route bus, but may be applied to general vehicles such as sightseeing buses and general one-box type wagon vehicles. It can be widely applied.

[0029]

As described above, according to the present invention,
When the slope plate is pulled out, the handover plate is automatically rotated and moved from the storage position to the drawout position in conjunction with this pull-out operation, and conversely, when the slope plate is pushed in, the handover plate moves from the drawout position in conjunction with this push-in operation. Since it is automatically rotated and moved to the stowed position, the crew and the like need only perform the work of taking in and out the slope plate. As a result, the operation can be speeded up, and when applied to a route bus or the like, effects such as easy management of operation time can be expected.
