Technical Field

The present invention relates to a handle attachment structure for attaching a slope device by turning it over.

Background

Patent document 1 and the like propose a slope device that can be deployed from a vehicle floor to the vehicle outside to form a slope surface so that a wheelchair and the like can get on and off a car, a bus, and the like.

Although not described in patent document 1, the ramp device is provided with a handle so that the ramp device can be easily unfolded toward the outside of the vehicle when in use and can be easily turned over and stored inside the vehicle interior when not in use.

However, in the conventional mounting structure of the handle, a shaft-shaped mounting shaft portion is formed in the handle, and a mounting hole to which the mounting shaft portion is rotatably connected is provided.

Therefore, when the slope device is turned over and stored in the vehicle interior side, the mounting shaft portion of the handle does not rotate along the circular hole, and thus the slope surface may be in a floating state by the handle in a state where a load is applied to the slope device.

Disclosure of Invention

The invention aims to provide a handle structure of a slope device, which is used for smoothly storing a handle when the slope device is stored.

The handle mounting structure of a slope device according to the present invention is a handle mounting structure for a slope device, which is used for performing a deployment operation of a slope device, and is characterized in that the slope device has a handle for performing a deployment operation and a mounting portion to which the handle is rotatably mounted, the mounting portion having a mounting hole, the handle having a mounting shaft portion rotatably coupled to the mounting hole, and the mounting hole having a long hole shape.

Here, it is preferable that a connection angle (θ) between the long axis center line of the long axis direction of the long hole shape and the slope surface is an acute angle.

The reason why the mounting hole is formed in the shape of the elongated hole is that the handle is easily tilted toward the slope device side by the movement of the mounting shaft portion along the elongated hole.

Therefore, the following manner may be adopted.

For example, the following are enumerated: the ramp device has a handle that performs a deployment operation and a mounting portion to which the handle is rotatably mounted, the handle having a first link coupled to a mounting shaft portion that is rotatably coupled to the mounting portion and a second link connected to the first link; and the slope device has a handle for performing an unfolding operation and a mounting portion to which the handle is rotatably mounted, the mounting portion having a mounting hole, the handle having a mounting shaft portion rotatably coupled to the mounting hole, and a grip portion provided on a front end side of the handle, the grip portion being rotatable with a predetermined gap.

In the present invention, the slope device is not limited in its structure as long as it is deployed to the vehicle outside when a wheelchair or the like is up and down, can bridge between a road surface and a vehicle floor to form a slope surface, and can be inverted and stored on the floor side of the vehicle when not in use.

In the present invention, the handle is mounted on the lower surface side of the slope surface that is turned over to the vehicle compartment side, and is folded to fall to the slope device side by the self weight of the slope device.

In the mounting structure of the handle according to the present invention, the mounting hole that rotatably supports the mounting shaft portion of the handle has a long hole shape in cross section, and when the weight in the tilting direction of the slope device is applied to the handle, the mounting shaft portion moves along the long axis direction of the long hole, so that the front end side of the handle is easily tilted toward the slope device.

In addition, similar effects can be obtained by using a link structure for the handle or providing a rotatable gap in the grip portion instead of using a long hole.

Detailed Description

Hereinafter, an example of a mounting structure of a handle of a slope device according to the present invention will be described with reference to the drawings.

Fig. 4 partially shows the deployed front end side of the ramp device 10.

Fig. 4 partially shows a state in which the slope device is deployed toward the vehicle outside and a slope surface is formed between the road surface and the vehicle floor.

On the slope surface, an annular handle 12 is rotatably coupled to a mounting portion 11 provided on the slope device 10 side.

The ramp device 10 is turned inside the vehicle compartment so that the state in which the ramp device 10 is stowed (stored) on the floor 1 of the vehicle is shown in fig. 1 to 3.

The ring handle 12 has a shaft-like attachment shaft portion 12a on one side and a grip portion 12b on the other side, which can be grasped by a hand, and to which a collar is attached.

The mounting portion 11 fixed to the ramp device 10 side has a mounting hole 11a of a long hole, and a mounting shaft portion 12a of a handle is inserted and coupled to the mounting hole 11a in a rotatable manner.

The mounting shaft portion 12a has a circular cross section, the mounting hole 11a has a long hole shape having a short diameter and a long diameter, and a connection angle (mounting angle) θ between the long axis center line 13 on the long diameter side and the slope surface of the slope device 10 is an acute angle smaller than 90 °.

The operation of the handle 12 will be described with reference to fig. 1 to 3.

As shown in fig. 1, the slope surface of the slope device 10 is inclined toward the inside of the vehicle compartment so that the slope device 10 is stowed inside the vehicle compartment.

In a state where the handle 12 is suspended directly downward, the grip portion 12b on the grip portion side abuts on the upper surface of the floor panel 1.

This load is transmitted to the mounting shaft portion 12a, but since the mounting hole 11a has an acute coupling angle θ, the mounting shaft portion 12a is offset along the long diameter of the long hole.

As a result, as shown in fig. 2 and 3, the grip portion side of the handle 12 is directly tilted, and the slope device 10 is smoothly stored in the vehicle interior.

Next, an example of a handle of a link structure will be described as another embodiment.

Fig. 5 shows a state where the handle 12b is lifted from the mounting portion 11 and set upright, and fig. 6 shows the movement of the handle 12 when the slope device 10 is turned toward the vehicle floor 1 side.

When the ramp device 10 is deployed toward the vehicle outside, as shown in fig. 4, the mounting portion 11 is located near the front end of the upper surface of the ramp device.

The mounting portion 11 has a mounting hole 11b, and a mounting shaft portion 12a on the side of the handle 12 is rotatably connected thereto.

A pair of first links 13 are connected to both ends of the mounting shaft portion 12 a.

The second link 14 is connected to a front end portion of the first link 13 via a connecting portion 13 a.

Both end portions of the pair of second links are connected by a shaft portion 15, and the grip portion 12b is rotatably attached to the shaft portion 15.

Thus, as shown in fig. 6, when the slope device 10 is turned inside the vehicle and the grip portion 12b abuts against the floor 1, the grip portion 12b is tilted toward the slope device so as to be folded at the connecting portion 13a between the first link 13 and the second link 14, and therefore, the slope device is stored on the floor 1 by its own weight.

The embodiment shown in fig. 7 is an example in which the front end side of the handle 12 is formed on the shaft portion 12d, and the grip portion 12b is attached to the shaft portion 12d with a gap 12c of 0.2mm to 1 mm.

By setting a predetermined gap (clearance) between the grip portion 12b and the shaft portion 12d receiving the grip portion 12b in this manner, the grip portion 12b is allowed to rotate freely like a drum, and therefore, as shown in fig. 8, the handle 12 is easily tilted toward the sloping device side.
