DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope plate device mounted on a vehicle, such as a bus, which is mounted on an entrance of a vehicle to enable passengers to get on and off.

[0002]

2. Description of the Related Art As a slope plate device to be mounted on a vehicle of this type, the applicant has previously filed Japanese Patent Application No. 9-139438, in which a slope plate is housed in a slope plate storage section. The electric motor automatically moves in and out of the storage position and the use position where it is taken out of the slope plate storage section and held in an inclined state between the floor surface of the entrance and exit and the ground, and the position of the disabled In this way, passengers using wheelchairs can easily get on and off. In the use position where the slope plate is held in an inclined state between the floor surface of the entrance and exit and the ground, an auxiliary plate rotatably provided above the opening of the slope plate storage unit is provided with the slope plate and the entrance and exit. It closes the gap that exists between the floor and the floor of the vehicle, thereby ensuring the safety of passengers when getting on and off.

[0003]

However, in such a conventional slope plate device mounted on a vehicle, when the slope plate is taken in and out between the storage position and the use position, the tip of the auxiliary plate is formed by the slope plate. Because it is in contact with the upper surface where passengers get on and off, contact resistance occurs between the slope plate to be taken in and out and the auxiliary plate, especially when a non-slip mat is laid on the upper surface of the slope plate to prevent slipping when getting on and off. The contact resistance between the slope plate to be taken in and out and the auxiliary plate increases, requiring a large operating force to exceed the contact resistance when taking in and out of the spool plate, and preventing slippage by laying on the top surface of the spool plate by repeatedly taking in and out the spool plate. The tip of the auxiliary plate that comes into contact with the mat may be worn, or the tip of the auxiliary plate may damage the non-slip mat. The resulting difficult problem there is.

The present invention is directed to an auxiliary plate for closing a gap between a slope plate and a floor of an entrance / exit portion at a use position where the slope plate is held in an inclined state between the floor surface of the entrance / exit and the ground. However, when the slope plate is put in and out between the storage position and the use position, the tip portion does not come into contact with the upper surface of the slope plate, and a slope plate device mounted on a vehicle that can satisfactorily put in and out the slope plate. The task is to provide.

[0005]

SUMMARY OF THE INVENTION Therefore, a slope plate device provided in a vehicle according to the present invention has a slope plate storage portion provided below a floor surface of a vehicle entrance and having an opening toward the entrance. And a storage position stored in the slope plate storage portion and a use position held in an inclined state between the floor surface and the ground of the entrance / exit portion, and a slope plate storage portion is provided between the storage position and the use position. A slope plate to be put in and out through the opening, and a slope plate that is rotatably provided above the opening of the slope plate storage part. An auxiliary plate for closing a gap existing between the opening and the floor surface of the mouth, the auxiliary plate having a rotating member at a position below and facing the slope plate and not interfering with the upper surface of the slope plate, Is between the storage position and the use position. A cam member that comes into contact with the rotating member of the auxiliary plate when inserted, the rotatable member is rotatably provided in contact with the cam member, and the tip end of the auxiliary plate is provided on the upper surface of the slope plate as the cam member comes into contact with the rotating member. The auxiliary plate is formed in a rotating shape so as not to contact with.

According to the slope plate device provided in the vehicle according to the present invention, the tip of the slope plate comes into contact with the upper surface of the slope plate where the passenger gets on and off at the use position of the slope plate, and the slope plate and the floor of the entrance / exit portion are in contact with each other. The auxiliary plate, which closed the gap between them, pivots as the rotating member comes into contact with the cam member of the slope plate when the slope plate is moved in and out between the storage position and the use position. The part is disengaged from the upper surface of the slope plate, and the rotating member rotates in contact with the cam member to reduce contact resistance. Therefore, when the slope plate is moved in and out between the storage position and the use position, the tip of the auxiliary plate can be prevented from contacting the upper surface of the slope plate, and the slope plate can be moved in and out satisfactorily.

A wall 4C is not formed at one end of the tip so as not to hinder the contact of the tip of 33 with the upper surface 4B.

As shown in FIGS. 3 to 5, reference numeral 36 denotes a roller member serving as a rotating member provided on the auxiliary plate 33. The roller member 36 is located on the lower end of the auxiliary plate 33 facing the slope plate 4 and on the upper surface 4B of the slope plate 4. L-shaped holding members 37 are attached to both outer positions in the width direction that do not interfere with each other. The roller member 36 is rotatably provided in contact with cam members 38A and 38B, which will be described in detail later, provided on the slope plate 4.

As shown in FIG. 1 to FIG.

It is provided. And the cam member 3
Reference numerals 8A and 38B denote a horizontal portion 39 formed substantially parallel to the slope plate 4 and an inclined portion formed by bending the leading end portion adjacent to the roller member 36 at the use position of the slope plate 4 in a downwardly inclined shape. The auxiliary plate 33 is formed in a shape that rotates so that the tip of the auxiliary plate 33 does not come into contact with the upper surface 4B of the slope plate 4 with the contact with the roller member 36.

Next, the operation of the above configuration will be described. FIG.
3 to 3, the slide member 7 is stopped at the operating position by the roller member 11 contacting the stopper member 6A, and the slope plate 4 has one end supported by the slide member 7 and the other end grounded to the ground 5. As a result, it is located at a use position where it is held in an inclined state between the floor 3 of the entrance 2 and the ground 5, and even a passenger using a wheelchair such as a physically handicapped person can easily get on and off. Then, by the contact of the roller member 11 with the stop member 6A, FIG.
As shown in (1), the roller members 31 of the support arms 27A and 27B are stopped at the inclined portion of the cam surface 30. The opening / closing lid 32 is provided at the position where the slope plate 4 is used.
7A and 27B, the opening of the slope plate storage portion 6 is opened by being prevented from turning upward. In addition, the auxiliary plate 33
Is rotated downward by its own weight, and its tip contacts the upper surface 4B of the slope plate 4 to close the gap H existing between the slope plate 4 and the floor 3 of the entrance 2 and the auxiliary plate 33 The roller member 36 on the lower surface of the cam plate 38A is close to the tip of the inclined portion 40 of the cam members 38A and 38B on the slope plate 4.

In the state shown in FIGS. 1 to 3 in which the slope plate 4 is located at the use position, the feed screw 1 is driven by the electric motor 8.
When the slide member 7 is moved from the operating position to the original position and stopped by rotating the rotation of the sliding member 7, the supporting arm 2 is moved as shown in FIG.
7A and 27B, the action point Y moves upward about the fulcrum X as the force point Z moves upward along the inclined portion of the cam surface 30 and moves to the horizontal portion, and the slope plate 4 moves upward. As a result, the sliding member 7 is lifted about the pivotal points pivotally supported at the distal ends of the supporting portions 17A and 17B, and is moved from the inclined state to the horizontal state while being moved from the inclined state to the slope plate storing section 6 through the opening of the slope plate storing section 6. It is inserted and located in the storage position.
Then, the opening / closing lid 32 is rotated upward by the elastic force of the torsion spring of the hinge 34 to close the opening. In addition, as the slope plate 4 is inserted into the slope plate storage portion 6 while the slope plate 4 is in a horizontal state from an inclined state, the roller member 36 is connected to the cam members 38A, 38B of the slope plate 4.
By contacting with the inclined portion 40 of the slope plate 4, the distal end portion is separated from the upper surface 4 </ b> A of the slope plate 4 to be in a horizontal state on the same plane as the upper plate 3 </ b> A, thereby forming a part of the floor surface 3. Then, when the auxiliary plate 33 is in a horizontal state on the same plane as the upper plate 3A, the roller member 36 comes into contact with the horizontal portions 39 of the cam members 38A and 38B to maintain the horizontal state of the auxiliary plate 33.

When the slope plate 4 is in the storage position, the feed screw 10 is driven to rotate in the opposite direction by the electric motor 8 to move the slide member 7 from the original position to the operating position shown in FIGS. When the slide member 7 is moved from the original position to the operating position, the support arms 27A and 27B move the inclined point through the state shown in FIG. As a result, the action point Y is moved down about the fulcrum X to the state shown in FIG. 3, and the slope plate 4 pushes the opening / closing lid 32 from the storage position stored in the slope plate storage portion 6 to push the slope plate. The slide member 7 is moved out through the opening of the storage portion 6 to the outside, and is lowered from the horizontal state by being pivoted at the pivotal points pivotally supported at the tips of the support portions 17A and 17B of the slide member 7 as the action point Y is moved downward. While in the state Situated in use position shown in FIGS. Then, the opening / closing lid 32 is pushed by the slope plate 4 against the elastic force of the torsion spring of the hinge 34 when the slope plate 4 moves from the storage position to the use position, and rotates downward,
The opening shown in FIGS. 1 to 3 is opened. Further, as the auxiliary plate 33 moves from the storage position of the slope plate 4 to the use position and the slope plate 4 is located at the use position while being inclined from the horizontal state, the roller member 36 is moved by the cam members 38A and 38B. By contacting the inclined portion 40 from the horizontal portion 39, the tip portion contacts the upper surface 4B of the slope plate 4 by rotating downward by its own weight, so that the tip portion contacts the slope plate 4 and the floor 3 of the entrance / exit portion 2. Close the existing gap H. And the auxiliary plate 3
In a state where 3 closes the gap H, the roller member 36 releases the contact with the inclined portion 40 of the cam members 38A, 38B and approaches the tip of the inclined portion 40.

In the movement of the slope plate 4 from the storage position to the use position, if an obstacle such as a passenger's foot comes into contact with the tip of the slope plate 4, the slope plate 4 resists the elastic force of the spring 23. The limit switch 26 is actuated relative to the slide member 7, and the electric motor 8 is controlled by the actuation of the limit switch 26 to rotate in the opposite direction to rotate the slope plate 4.
Is returned to the storage position, or the electric motor 8 is controlled to stop driving and stop the movement of the slope plate 4. For this reason, it is possible to automatically move the slope plate 4 in and out by the electric motor 8 without lowering the safety.

A spring 23 for urging the slope plate 4 by an elastic force is provided on the slide member 7 so as to support the one end of the slope plate 4 at one end so as to be relatively movable.
The rod member 24 housed inside the 7B and having a dog member 25 for actuating a limit switch 26 attached to the tip thereof protrudes from a pivotal portion of the slope plate 4 to support the support portions 17A, 17A.
B, the spring 23 and the rod member 24 can be arranged by using the supporting portions 17A and 17B that pivotally support one end of the slope plate 4 so as to be relatively movable.
A special space for disposing the rod member 24 can be eliminated. Further, since the switch for controlling the electric motor 8 is the limit switch 26 operated by the dog member 25, the operation of the switch can be ensured.

Further, supporting arms 27A and 27B pivotally supported by the slide member 7 and abutting against the lower surface of the slope plate 4 are provided, and the supporting arms 27A and 27B have sliding contact portions which come into contact with the cam surface 30. The pivot point between the slide members 7A and 27B with respect to the slide member 7 is the fulcrum X, and the support arms 27A and 27B.
The point of contact of the support arm with the lower surface of the slope plate 4 is defined as the point of action Y, and the sliding portion of the support arms 27A and 27B is defined as the point of force Z.
7A and 27B are movements between the original position of the slide member 7 and the operation position, and as the force point Z moves up and down along the shape of the cam surface 30, the action point Y moves up and down around the fulcrum X, The plate 4 is moved up and down between the storage position and the use position while being lifted and lowered around the pivot point to the slide member 7 as the action point Y moves up and down. For this reason, the lifting and lowering operation of the slope plate 4 is performed by the cam surface 30.
Can be set according to the shape of the slope plate 4, and an optimum lifting and lowering operation can be obtained according to the length dimension (the vertical dimension in FIG. 2) of the slope plate 4.

Further, when the slope plate 4 is moved from the use position to the storage position, the slope plate 4 is rotated upward by the elastic force of the torsion spring of the hinge 34 to close the opening of the slope plate storage portion 6 and to close the slope plate 4. Since the lid 32 is pushed by the slope plate 4 against the elastic force by the movement from the storage position to the use position and pivots downward to open the opening, the electric motor 8 is provided.
The opening and closing of the opening can be automatically performed when the slope plate 4 is moved in and out by the drive of the above, and a special operation for opening and closing the opening can be unnecessary.

With this operation, the tip end portion contacts the upper surface 4A of the slope plate 4 at the use position of the slope plate 4 to close the gap H existing between the slope plate 4 and the floor surface 3 of the entrance / exit portion 2. When the slope plate 4 is moved in and out between the storage position and the use position, the auxiliary plate 33 pivots as the roller member 36 comes into contact with the cam members 38A and 38B of the slope plate 4, and the leading end portion is rotated. Is released from the upper surface 4B of the slope plate 4, and the roller member 36 rotates in contact with the cam members 38A and 38B to reduce the contact resistance. For this reason, when the slope plate 4 is moved in and out between the storage position and the use position, the tip of the auxiliary plate 33 can be prevented from contacting the upper surface 4A of the slope plate 4, and particularly, getting on and off the upper surface 4A of the slope plate 4. Even when a non-slip mat is laid to prevent slippage at the time, the contact resistance between the slope plate 4 to be taken in and out and the auxiliary plate 33 can be increased, and the slope plate 4 can be taken in and out well.

The roller member 36 is a cam member 38
The auxiliary plate 33 is brought into contact with the horizontal portion 39 of
In order to maintain the same horizontal state as that of A, the slope plate 4
In the storage position, the auxiliary plate 33 is supported by the roller members 36 provided at both outer positions in the width direction in addition to the hinge 35, so that a part of the floor surface 3 can be formed well.

In one embodiment of the present invention, the auxiliary plate 3
3, the roller member 36 is provided as a rotating member, but is not limited thereto.
Of course, a ball member may be used instead. Further, although the feed screw 10 is rotationally driven by the electric motor 8, the slide member 7 is provided so as to be movable between the original position and the operating position. However, the present invention is not limited to this. For example, it goes without saying that a ball screw or endless cable may be used. Although the limit switch 26 is provided as a switch for controlling the electric motor 8,
It goes without saying that a proximity switch or the like may be used. In addition, the point of force Z that comes into contact with the cam surface 30 formed on the cam member 29 disposed on the bottom surface of the slope plate storage section 6 is defined by the support arms 27A and 27A.
The cam member 29 forming the cam surface 30 is arranged on the lower surface of the upper plate 3A of the slope plate storage portion 6, and the support arms 27A and 27B are connected to the fulcrum X.
It is a matter of course that a force point Z which extends further and which comes into contact with the cam surface 30 may be provided at the extended end portion. Further, although two support parts 17A and 17B, two limit switches 26, and two support arms 27A and 27B are provided, it is needless to say that one each may be provided.

As described above, according to the present invention, when the slope plate is moved in and out between the storage position and the use position, the tip of the auxiliary plate can be prevented from coming into contact with the upper surface of the slope plate. Even when a non-slip mat is laid on the upper surface to prevent slippage when getting on and off, the contact resistance between the slope plate to be taken in and out and the auxiliary plate can be increased, and the slope plate can be taken in and out well.
