Description

  In the present invention, a slope surface is formed by deploying between an upper stage and a lower stage having a step such as an entrance, or a slope surface is formed by deploying between a floor portion of a vehicle and the ground surface. The present invention relates to a slope device that facilitates getting on and off of a wheelchair and the like, and enables a multipurpose use by holding a slope surface in a horizontal state.

As a slope device that forms a slope surface on a stepped part of a building or a vehicle floor surface and a stepped part such as the ground, a plurality of slope members are folded and stored, and when used, a folding type that is deployed in a straight line, There is a slide type in which the slope member slides and expands.
In any of the above types, conventionally, the storing and unfolding operations are difficult and the purpose is to form a slope surface, and other methods of use have not been studied.

Patent Document 1 discloses a lifter that raises a proper position on the front end side of a slide slope unit to a predetermined height, although it is intended to facilitate fixing of a wheelchair or the like.
Although it is possible to hold the slide slope unit approximately horizontally with this lifter, not only is it troublesome to deploy and store the lifter, but the lifter is provided on the tip side of the slope, which increases the weight of the slope. In addition to the problem, there is a problem that the center of gravity of the slope has to move to the tip side.
Furthermore, when the road surface is not flat, both feet of the lifter become unstable on landing.

  The present invention provides a slope device that is excellent in deployment and storage operability of the slope device and that can hold the slope surface horizontally not only in the slope state in which the slope surface is inclined but also in a state in which the slope device is slid down. Objective.

A slope device according to the present invention includes a base slope member having one end rotatably attached to a base for attaching the slope device by a rotary shaft, and a slide slope connected to the other end of the base slope member so as to be slidable and extendable. The base slope member has a locking means for holding the slide slope member in a horizontal state in a state where the slide slope member is slid and stored in the base slope member, and the slide slope member is slid and extended from the base slope member. unlocks means is rotatable to the tip of the slide slope member is grounded to the ground, locking means for holding the base slope member in a horizontal state, of the rotation axis of the base slope member was at the distal end A sliding member that is slidable by a predetermined distance between the tip direction and the rotation axis direction, and Means lifting supports lifting the id member, together with the having a stopper member for restricting the sliding movement of the slide member, the stopper member is provided rotatably about the shaft portion on the base slope member, the sliding slope member Is moved to the base slope member side, the slide member moves in the distal direction, one end of the stopper member comes into contact with a restriction pin provided on the slide slope, and the other end of the stopper member is rotated by the slide member. It restricts the movement in the direction of the moving shaft, and as the slide slope is extended in the distal direction, the regulating pin moves in the distal direction, and the stopper member can be turned. It is characterized by allowing movement in the direction .

Here, the base part for attaching the slope device refers to an attachment part on the upper stage side that is attached to form a slope surface, such as a vehicle floor part, an entrance upper part part of the entrance, and the attachment form is not limited.
Further, the locking means for holding in a horizontal state means, for example, a means for storing in a standing state in a vehicle, allowing the slope device to turn to the horizontal state toward the outside of the vehicle, and locking to prevent further rotation. In addition, it is intended to include a locking means for holding the building in a horizontal state in advance on the upper stage side of the building.

In the present invention, the locking means for holding the base slope member in a horizontal state is a distal end side with respect to the rotation axis of the base slope member, and a slide member that is slidable by a predetermined distance between the distal direction and the rotation axis direction; The slide member has a lifting means for lifting and supporting the slide member, and a stopper member for restricting the sliding movement of the slide member. When the slide slope member is housed in the base slope member, the slide member is positioned on the distal direction side. In addition, the base slope member maintains a horizontal state by restricting movement by the stopper member, and the slide slope member has unlocking means for rotating or retracting the stopper member when sliding and extending from the base slope member. The sliding member may be allowed to move in the rotational axis direction.
Further, the locking means for holding the base slope member in a horizontal state includes a rotation restricting member for restricting the base slope member from rotating more than the horizontal state,
The slide slope may have a lock releasing means for rotating or retracting the rotation restricting member when extending from the base slope.

In the slope device according to the present invention, the slide slope member is slidably accommodated with respect to the base slope member, and in this accommodated state, the horizontal state is maintained or locked so as to rotate only to the horizontal state. As a result, the slope surface is kept horizontal.
In this horizontal state, it can be temporarily placed on the baggage, so it is convenient for taking in and out of the baggage indoors or in the car, and can be used for other purposes.
When the slide slope member is pulled out from this horizontal state, the locking means is released in conjunction with the operation, and the slide slope member can be developed into a slope state.
Therefore, the operation of expanding to the slope state is easy.

An example of a combination of a slide member and a lifting wire is shown as a horizontal holding lock means. (A) shows a stowed storage state, (b) shows a horizontal state, and (c) shows a slope state. The enlarged view of a slide part is shown. An example in which a link mechanism is used as means for lifting the slide member will be described. An example of a combination of a rotation restriction member and a rotation restriction release cable as a horizontal holding lock means will be shown. An example of a combination of a rotation restricting member and a stopper as a horizontal holding lock means is shown.

  As an example of the structure of the slope device according to the present invention, an example in which the slope device is attached to the floor of a vehicle will be described below, but the attachment location is not limited to the present embodiment.

In the present embodiment, the slope device 100 is stored in a standing state in the vehicle compartment of the vehicle 1 as shown in FIG. 1, for example, the back door 2 is opened, and is in a horizontal state outside the vehicle as shown in FIG. Is rotated so that it is held in a horizontal state as it is.
The slope device has a structure example in which the slide slope member 20 is slid and housed on the base slope member 10, and when the slide slope member 20 is pulled out, the locking means for holding the horizontal state is released, as shown in FIG. Thus, the slope surface is formed by extending the slide slope member 20 and grounding its tip to the ground surface.

Specific examples of the structure will be sequentially described below.
In the first embodiment shown in FIGS. 1 and 2, one end of the base slope member 10 on the vehicle side is rotatably connected to the base portion of the floor portion 3 of the vehicle 1 by a rotation shaft 4.
A slide member 32 is attached to the side surface portions on both sides of the base slope member so as to be slidable along the slide hole 11 having a long hole provided in the rotation axis direction and the distal direction, with respect to the rotation shaft 4. It has been.
In a state where the slide member 32 is positioned on the distal end side of the slide hole 11, one end of the stopper 12 having a generally heft shape when viewed from the side is pressed by the restriction pin 21 provided on the slide slope member 20 side, and the slide member 32 rotates. The movement in the direction of the axis 4 is restricted.
The stopper 12 can be rotated around the shaft portion 13 on both sides of the base slope member 10, and the slide slope member 20 is accommodated in the base slope member 10 in the state shown by the solid line in FIG. 2. In this state, the upper portion 12a of the stopper 12 comes into contact with a restriction pin 21 provided on the slide slope member 20, and the lower end side 12b of the stopper 12 restricts the movement of the slide member 32.
When the slide slope member 20 is pulled out as shown by a dotted line in FIG. 2, the regulating pin 21 is separated from the upper portion 12a of the stopper 12, and thereby the stopper 12 can be rotated clockwise in FIG. Becomes movable in the direction of the rotation shaft 4.
The slide member 32 is connected to a lower end 31 b of the wire 31 as an example of the horizontal holding means 30, and the upper end 31 a of the wire 31 is fixed on the vehicle side and above the rotating shaft 4.
As shown in FIG. 1B, the length of the wire 31 is positioned on the tip side of the slide hole 11, and the base slope member 10 is held horizontally when the movement is restricted by the stopper 12. It is such a length.
In the present embodiment, both ends of a wire having a predetermined length are fixed, but the maximum length may be regulated by using a vehicle side winding method.
When the slide slope member 20 is pulled out from this state, the restriction of the stopper 12 is released, and the slide member 32 can be moved in the direction of the rotation shaft 4. Only the base slope member 10 rotates to the ground side.
Thereby, a slope surface is formed.
Conversely, when the slope device is stored, the tip end side of the slide slope member 20 is lifted and pushed into the vehicle side while being in a substantially horizontal state.
Due to the force in the pushing direction, the slide member 32 moves to the tip side along the slide hole 11, and the lower end side 12 b abuts against the slide member 32 at the stopper 12.
As a result, the horizontal state can be maintained only by providing simple storage maintaining means such as hook claws and lock claws for maintaining the state in which the slide slope member 20 is stored in the base slope member 10.
Thereafter, it is only necessary to perform an operation of stowing and storing the slope device 100. Since there is no need to provide a lift on the tip side as in the prior art, the center of gravity is located closer to the rotating shaft than in the prior art, so the operation is easy.

FIG. 3 shows a second embodiment in which a link mechanism is used instead of the wire as a means for lifting the slide member.
The first link 41 on the vehicle side and the second link 42 on the slope device side are articulated, and the base slope member is held in a horizontal state by the link.
As a link structure, the first link 41 and the second link 42 can be rotated by a shaft 41b, one end 41a of the first link is attached to the vehicle side, and the end 42a of the second link 42 on the slope device side. 3 is not limited to the example of FIG. 3 as long as the slide member 32 is rotatably connected to the slide member 32.
In the present embodiment, the shortening direction elastic member 43 is provided between the first link and the second link so that the slope device can be easily raised.
The second embodiment is the same as the first embodiment except that the end portion 42a of the second link 42 is fixed to the slide member 32.

FIG. 4 shows a third embodiment in which the rotation of the base slope member 10 is limited by a rotation restricting member 50. The rotation restricting member 50 is elastically biased by an elastic material 52 in the standing direction, and the protruding tip side 50a. Is held in a horizontal state in a state where it contacts the seat portion 5 provided on the vehicle side.
The other end 22a of the cable 22 having one end fixed to the connecting portion 21 provided on the slide slope member 20 side is connected to the connecting portion 53 from the tip of the bracket 50, and pulling out the slide slope member 20 causes the cable tension to be increased. Thus, the bracket 50 is rotated to the tip side with the shaft portion 51 as the center of rotation, and the cable becomes longer along the extension of the slide slope member.
Thereby, it becomes a slope shape as shown in FIG.

FIG. 5 shows a fourth embodiment in which a rotation restricting member 60 including a top 60 is used.
In FIG. 4, the top 60 has a long shape protruding toward the base slope member, is pivotally supported by the shaft portion 61, and the top 60 is biased by the elastic member 63 in the clockwise direction. .
When the slide slope member 20 is housed in the base slope member, it is restricted by the stopper 112, the top 60 is in the standing state, and the protrusion 62 of the top 60 abuts against the seat 5 as shown in FIG. When the slope device is held in a horizontal state and the slide slope member 20 is pulled out, the top 60 rotates and becomes sloped by the stopper 112 being separated.
