Description

  The present invention relates to a slope device that is mounted on a vehicle and that can form a slope surface toward the ground or the like when a wheelchair or the like moves up and down.

There is a type in which the slope device is accommodated in a state where the slope is tilted to the floor side in the vehicle cabin when not in use.
In this way, when the slope is accommodated so as to lie on the vehicle interior side, the floor of the vehicle interior can be widely used as a luggage compartment or the like.

For example, Patent Document 1 discloses an N-stage slide slope, and when a striker is provided on a sliding slope and a catcher is provided on the floor of the vehicle body, when the slide slope moves forward, the striker hits the catch. Disclosed is a lock structure that contacts.
Thereby, it is possible to prevent the slide slope from jumping out unintentionally.
However, in the structure in which the catcher or the like is attached to the floor of the vehicle in this way, it is necessary to adjust the attachment between the mounted slope device and the vehicle side.
In addition, as described in the publication, when a load that deforms the floor of the vehicle is received, the striker of the slope interferes with the catch of the floor of the vehicle body, and the shock absorption due to the deformation of the floor is sufficiently effective. In this case, there is a technical problem that requires a special structure for escaping the striker from the catcher.

Japanese Patent No. 4000548

  An object of the present invention is to provide a slope device that can be mounted on a vehicle and that can prevent a slide slope from popping out with a simple structure when inverted and housed inside a vehicle interior.

  The slope device according to the present invention rotates to the outside of the vehicle compartment of the vehicle and forms a slope surface toward the ground, and the accommodation state that is reversed to the vehicle interior side of the vehicle and accommodated in the vehicle compartment. The slope device includes a base slope that is rotatably connected to a vehicle, and a slide slope that slides and expands from the base slope, and is provided between the base slope and the slide slope. And a locking means for restricting the movement of the slide slope.

Here, the base slope is a slope in which one end side is rotatably connected to the vehicle side, and there is no limitation on the structure as long as the base slope is connected to the vehicle side so that the vehicle can be mounted. There are no restrictions on the mounting of the rear and sides.
As long as the slide slope expands and contracts from the base slope, not only one slide slope but also a plurality of slide slopes may be provided in a multistage manner.

  In the slope device according to the present invention, since the mutual lock means for locking the movement of the slide slope is provided between the base slope and the slide slope, it is not necessary to provide a movement restriction means for the slide slope such as a catcher on the vehicle side. Therefore, the degree of design freedom is increased accordingly.

In the present invention, the lock means may be in a lock-on state in the housed state, and switch to a lock-off state when the base slope rotates in an inverted direction.
Furthermore, the lock means may include a lock member, and the lock member may be switched between an on state and an off state by its own weight.
Here, the structure of the lock member is not limited as long as the lock member is switched between the lock-on state and the lock-off state with the rotation of the slope due to its own weight.
For example, a structure that slides in the protruding direction and the immersion direction by its own weight, and a structure that rotates (rotates) in the lock-on direction and the lock-off direction by its own weight are given as examples.
In the present invention, the lock means may adopt a mode comprising a lock pin biased in a protruding direction provided on the base slope and an insertion hole into which the lock pin provided on the slide slope is inserted. .
If it does in this way, in the accommodation state, since the lock pin is urged | biased toward the insertion hole, the movement of a slide slope is controlled.
At this time, if the front end side of the lock pin is urged so as to come into contact with the peripheral portion of the insertion hole, the slide slope is prevented from rattling during the traveling of the vehicle.
When the slope is rotated out of the passenger compartment and the slide slope is extended and developed, an inclined surface is formed at the tip of the lock pin, and the lock pin can be immersed by a force for pulling out the slide slope.
In addition, the lock pin can be removed from the insertion hole against an urging force by pulling a knob or the like provided on the lock pin by the operator.

  The slope device according to the present invention has a locking means between the slide slope and the base slope so that the slide slope does not jump out when the slope is housed in an inverted state on the vehicle interior side. There is no need to provide a means for restricting the movement of.

In the slope device according to the present invention, the lock means is turned on when the slope is housed inside the vehicle interior, and the lock device is turned off when the slope is rotated in the inverted direction to deploy the slope to the outside of the vehicle interior. In this state, the slide slope can extend from the base slope to form a slope surface.
In this case, if it is possible to switch on and off by the weight of the lock member, it is not necessary for the person who expands and houses the slope to switch the lock means on and off. Yes, the problem of forgetting to switch is solved.
Moreover, in the aspect which inserts a lock pin in the insertion hole by the side of a slide slope with urging | biasing force, it can expand | deploy only by once immersing a lock pin against urging | biasing force.
