The inner surface of the door 10 is formed as a platform 20 and constitutes a surface on which a wheelchair is loaded. The lifting / lowering operating section 40 has a lifting / lowering mechanism for the door 10.

First, the door 10 has a substantially square shape on one side, and is formed in a substantially planar shape as a grounding surface when the platform 20 is grounded. Also, since the back surface is used as the platform 20, it has an area and strength suitable for loading a wheelchair. The door 10 is provided with a door lock portion 30 for locking the door 10 to the vehicle body 70. Door lock 3
Reference numeral 0 denotes a lock means and an operation lever, which are configured so as not to protrude from the surface of the door 10. Note that the door 10 is
Is preferably formed of the same material as the vehicle body 70.

Next, since the platform 20 formed on the inner surface of the door 10 is a portion for loading a wheelchair, the platform 20 is formed in a flat shape and can withstand the load even when the wheelchair or a wheelchair and an attendant are loaded. Has strength. or,
The platform 20 forms an inner surface of the vehicle body 70 when the door 10 is in a substantially vertical state, and forms a surface on which a wheelchair is mounted on the upper surface when the door 10 is in a substantially horizontal state.

Further, the thickness of the door 10 is formed so as to decrease toward the front end in the opening and closing direction. Thereby, when the door 10 is in contact with the ground, a step with respect to the ground at the tip end is eliminated, and the entry of the wheelchair is facilitated. The other end of the door 10 is
Is formed to have a predetermined thickness in order to connect to the substrate. still,
The door 10 may be formed in a plate shape with a predetermined thickness, but in this case, it is necessary to provide a slope at the tip of the door 10 in order to facilitate entry of the wheelchair.

Next, the lifting / lowering operating section 40 is mounted on the main body frame 7.

The lifting / lowering operating section 40 has lifting / lowering means for lowering or raising the platform 20 while maintaining the horizontal state. An opening / closing operation unit 50 that rotates the door 10 from a substantially vertical state to a horizontal state is provided inside the door 10 and is connected to the lifting / lowering operation unit 40 by an opening / closing arm 51.

A control box section 72 for controlling the lifting / lowering operation section 40 and the opening / closing operation section 50 is provided on the vehicle body 70 around the door 10 at a position where the door 10 can be easily operated. The control box section 72 is installed on the outer surface of the vehicle body 70 in order to avoid a malfunction during traveling. However, the control box section 72 may be installed inside the vehicle body 70 to enable operation from inside the vehicle. Here, a cushion material can be provided on the outer surface of the door 10 in order to avoid damage and appearance damage when grounded. For example, a cushion material of an appropriate size made of rubber or synthetic resin may be provided at the four corners or two opposing sides of the door 10. This allows
In addition to avoiding damage to the door 10, when the wheelchair is loaded on the platform 20 and the door 10 is lowered, it is possible to reduce the impact at the time of touchdown. In order to improve the confidentiality of the vehicle, a packing material may be provided on the outer edge of the door 10 on the inside of the vehicle, and a packing material may be provided on the door opening of the vehicle body 60 in the same manner.

The platform 20 may be provided with a wheelchair wheel stopper 60 at the wheelchair entry portion. Further, a bar-shaped edge 21 rising from the surface of the platform 20 may be provided on the side. This edge 21
When the door 10 is closed, it also serves as a handle for the occupant.
The edge 21 may be a plate-like edge 21 rising from the surface of the platform 20. Further, it is also possible to mount a slip-preventing means between the vehicle body floor 71 and the platform 20, for example, a protective roller curtain or the like from the opening end of the door 10 of the vehicle body floor 71 to the upper surface of the platform 20 on the opening side. Thus, no matter how the wheelchair is loaded on the platform 20, the wheelchair can be prevented from sliding down in all directions. The platform 20 may be provided with a number of small projections or grooves on the surface thereof or an anti-slip sheet may be attached to the surface of the platform 20 in order to prevent the wheelchair from accidentally sliding.

Next, as shown in FIG. 4, the lifting / lowering operating section 40 mainly includes a main shaft 41, a main plate 42, a main arm 43, a sub arm 44, an adjustment bolt 4
5, the link unit 47 and the cylinder 49. The main shaft 41 includes the door 10 and the vehicle body floor 7.
1 and is rotatably locked to the main body frame 73 to form a fulcrum (a). Further, the main shaft 41 is connected to a cylinder 49 to perform a rotating operation.

The main plate 42 includes a main shaft 4
Fixed by welding on both sides each of 1 to rotate about the fulcrum (A) by the main shaft 41. Main plate 42
Is provided with a shaft support portion of the main arm 43 and a locking portion of the adjustment bolt 45 on a circumferential portion thereof. Main arm 4
3 is pivotally supported by a main plate 42 and a link portion 47 serving as a connection portion to the door 10. That is, the main arm 4
One end of 3 is rotatably locked to a circumferential portion of the main plate 42 on the door 10 side to form a fulcrum (f). Further, the other end of the main arm 43 is rotatably locked to a lower portion of the link portion 47 and forms a fulcrum (d).

The adjustment bolt 45 is pivotally supported by the main plate 42 and the main arm 43, and regulates the rotation of the main arm 43 with respect to the main plate 42. One end of the adjustment bolt 45 is rotatably locked to a circumferential portion of the main plate 42 above the fulcrum (f), and forms a fulcrum (e). The other end of the adjustment bolt 45 is rotatably locked at substantially the center in the length direction of the main arm 43. Further, the adjusting bolt 45 is provided with a contact portion 46 which contracts from a predetermined length by a piston cylinder mechanism.
Having. Accordingly, the main arm 43 is restricted from rotating downward about the fulcrum (F) by the support of the fulcrum (F) and the adjustment bolt 45, and the contact portion 4
6 is configured to rotate only upward by contraction.

The sub arm 44 is pivotally supported by the main body frame 73 and the link portion 47. That is, the sub arm 44
Is rotatably locked to the main body frame 73 to form a fulcrum (b). The fulcrum (b) is formed so as to be vertically above the fulcrum (a). Also, sub arm 4
The other end of 4 is rotatably locked at a vertical position above the fulcrum (d) of the link portion 47 to form a fulcrum (c). Therefore, the fulcrums (a), (b), (c), and (d) are configured so as to be located at the vertices of a parallelogram as a whole, and constitute a link mechanism when performing the elevating operation. In addition, these fulcrums (a)
Of (b), (c) and (d), (b) and (b) are located in the vertical direction, so (c) and (d) also move while always maintaining the vertical state. The movement is supported by the main arm 43.

The link portion 47 is supported by fulcrums (d) and (c), and rotatably locks the door 10 coaxially with the fulcrum (c). The door 10 is locked to the link portion 47 so as to be flush with the vehicle body floor 71 in a horizontal state. When the door 10 is in a horizontal state, the link portion 47 is provided with a fulcrum (c).
(D) abuts on the door 10 on the door 10 side of the line connecting the
Has a door contact portion 48 for maintaining the horizontal state.

In the lifting / lowering operating section 40 having the above configuration,
The load on the platform 20 applies a compressive force to the main arm 43 via the fulcrum (c) and (d) of the link portion 47,
Each of the sub-arms 44 generates a tensile force, and
7 is kept constant. Therefore, the entire load on the platform 20 at the time of lifting and lowering is applied to the fulcrum (d), and this load is caused by the pulling of the fulcrum (e) and the fulcrum (f).
The compression is received.

Next, the opening / closing operation section 50 is provided inside the door 10, and includes an opening / closing arm 51 and a cylinder that slides the arm 51 in the longitudinal direction. One end of the opening / closing arm 51 protrudes from the door 10 and is rotatably supported near the door contact portion 48, and the other end is connected to a cylinder at the opening / closing operation portion 50. Hereinafter, the operating states of the lifting / lowering operating unit 40 and the opening / closing operating unit 50 will be described.

Until the door 10 rotates from the closed state and the platform 20 comes to a substantially horizontal position, the opening / closing operation section 50 is
It works as follows. When the door 10 is closed, the opening / closing arm 51 projects from the door 10 and extends, and stands up the door 10 that rotates about a fulcrum (c). In this state, when the cylinder pressure decreases, the opening / closing arm 51 moves to the opening / closing operation section 50 side due to the weight of the door 10 and the door 1
The protrusion from zero is reduced. Therefore, the distance between the opening / closing operation part 50 and the door contact part 48 is shortened, and the door 10 is supported by the fulcrum (c).
And rotate to the open state. Further, when the door 10 rotates until it is flush with the vehicle body floor 71, the door 10 comes into contact with the door contact portion 48, and further downward rotation is regulated, and the horizontal state is maintained.

When the door 10 is closed, the operation is the reverse of the above, and the opening / closing arm 51 protrudes and the link 4
The door 10 is returned to the closed state by pushing up the door 10 from 7.
Next, the lifting / lowering operating section 40 operates as follows. First, the lifting / lowering operating section 40 operates as follows until the platform 20 is in contact with the vehicle body floor 71 from a horizontal state to a ground contact.

The door 10 and the platform 20 are moved up and down by a fulcrum (a) (b) (c) (d) link mechanism. When the pressure of the cylinder 49 is gradually released, the main shaft 41 rotates downward around the fulcrum (a) by the weight of the door 10. At the same time, the main plate 42, the main arm 43 and the adjustment bolt 45 also rotate downward at the same rotation angle. With the rotation of the main arm 43, the parallelogram link formed by the fulcrums (a), (b), (c), and (d) loses support, and the sub-arm which is one of the arms forming the parallelogram. 44 also rotates downward. Accordingly, the main arm 43 and the sub-arm 44 rotate and move their respective turning radii at the same angle, and the fulcrum (a) (b)
With the link mechanism of (c) and (d), the fulcrum (c) and (d) of the link portion 47 vertically move up and down.

Next, after the platform 20 is in contact with the ground and then descends toward the contact surface, the lifting / lowering operating section 4 is moved.
0 operates as follows. While the platform 20 is descending, the fulcrum (c) and the fulcrum (d) are always in the vertical position, and always hold the link 47 in a fixed direction. However, even when the link portion 47 is grounded, the pressure of the cylinder 49 continues to be released.
2 still rotates downward. Thereby, the piston cylinder mechanism of the contact portion 46 of the adjustment bolt 45 contracts, and the main arm 43 rotates toward the adjustment bolt 45 around the fulcrum (f). Therefore, the rotation of the main plate 42 causes the main arm 43 to retreat in the direction opposite to the position of the link portion 47, and the radius of rotation of the main arm 43 is reduced. Then, the fulcrum (d) is slightly shifted from the vertical position below the fulcrum (c) to the main shaft 41 side, and the link portion 47 is slightly inclined downward from the state during the elevating operation. Therefore, the platform 20 held horizontally by the door contact portion 48 of the link portion 47 is in a state in which the tip portion is inclined downward from the horizontal state toward the ground contact surface due to its weight.

On the other hand, when the platform 20 is raised, the lifting / lowering operating section 40 performs the reverse operation. First, the platform 20 returns to the horizontal state from the state inclined toward the ground contact surface. In this state, the contact portion 46
The main arm 43 returns to a state where the main arm 43 restricts the rotation about the fulcrum (f) from the downward direction.
The horizontal state of 0 is maintained. Therefore, Platform 2
As long as 0 does not return to the horizontal state, the door 10 will not rise. On the contrary, the platform 20 is
As long as it does not touch the ground, it will remain horizontal.

The opening / closing section 50 is formed, for example, so that the main arm 43 or the sub arm 44 can be extended and contracted.
It can be omitted by integrally configuring with the lifting / lowering operation unit 40. When the main arm 43 expands and contracts, the fulcrum (d) rotates around the fulcrum (c), and when the sub arm 44 expands and contracts, the fulcrum (c) rotates about the fulcrum (d). It will move and open and close the door 10.

Next, the wheelchair stopping means 60 of the wheelchair is shown in FIG.
As shown in FIG. 6, the wheel stopper 61 and the stopper 62, the spring shaft 63 and the spring 64 are provided. The wheel stopper 61 is formed of a substantially U-shaped cross section having a length, width, thickness, and strength capable of preventing the wheel from slipping. The wheel stopper 61 is rotatably locked in a groove provided at the distal end of the platform 20 with the open portion downward, with a pivot point at the distal end side of the platform 20. In addition, the wheel stopper 61 is configured to be flush with the platform 20 when positioned in the groove. Further, one end of a spring shaft 63 is rotatably locked to a lower portion of the wheel stopper 61, and the other end of the spring shaft 63 is inserted into a groove lower portion of the wheel stopper 61 on the open side, and the wheel stopper 61 stands up. In such a state, the nut is screwed so as not to come out of the insertion hole and formed. A spring 64 is interposed between the wheel stopper 61 and the groove of the platform 20 through the spring shaft 63 to urge the wheel stopper 61 to stand.

Next, on the surface of the platform 20 on the open side of the wheel stopper 61, the wheel stopper 61 is opened when the wheel stopper 61 is positioned in the longitudinal direction, and when the wheel stopper 61 is rotated at a right angle, the wheel stopper 61 is connected to the platform 20. A substantially rectangular stopper 62 is rotatably locked by a bolt or the like at a position where the stopper 62 is pressed flush. Therefore, the wheel stopper 61
In a state where the stopper 62 is unlocked, the stopper 62 is erected by the spring 64 to prevent the wheelchair from slipping. When a wheelchair is placed on the platform 20, the platform 20
If the wheelchair is pushed in as it is, the wheel stopper 61 is pushed by the wheel of the wheelchair and becomes flush with the platform 20, so that the wheelchair can be moved smoothly. After the movement is completed, the wheel stopper 61 is
4 to return to the standing position. Conversely, when the wheelchair is lowered from the platform 20,
When the wheel stop 61 is unnecessary, the wheel stop 61 can be pressed with a foot or the like, and the stopper 62 can be turned at a right angle to lock the wheel stop 61, thereby keeping the wheel stop 61 flush with the platform 20.

The wheel stopper means 60 can be raised and closed by a hydraulic cylinder or the like instead of the spring shaft 63 and the spring 64. Regarding the mounting position of the door 10 and the lifting / lowering operation unit 40 to the vehicle body 70,
Although it is possible to change the normal entrance, it is possible to attach it, but in order to improve the getting on and off conditions for the physically injured or ordinary passenger, separately from the normal entrance, the range that does not affect the running function of the vehicle Can be installed with For example, in a bus having a front entrance, it can be added between wheelbases. Also, depending on the size of the bus and the position of the normal entrance, it can be installed on the side of the front part of the front wheel or on the side of the rear part of the rear wheel. In the case of a medium-sized or small bus, it can be installed on the rear surface of the vehicle body 70.
