Description

The present invention relates to a vehicle slope lock device and a vehicle slope lock system.

Patent Documents 1 and 2 disclose a conventional slope lock device for a vehicle. These vehicle slope lock devices are provided between a substrate provided on the vehicle body and a slope displaceably supported by the substrate. The slope can be displaced in the first direction and passed through the holding position, and can be displaced in the second direction opposite to the first direction and passed through the holding position. The vehicle slope lock device is for holding the slope in the holding position.

More specifically, the slope can be displaced between an upright holding position, a laterally projecting deployment position from the vehicle body, and a laterally extending accommodation position that overlaps the vehicle body.

In the vehicle slope lock device disclosed in Patent Document 1, the pin provided on the slope moves linearly and is inserted into the insertion hole of the lock portion provided on the substrate like a cannuki to hold the slope in the holding position. It is designed to hold.

Hereinafter, examples embodying the present invention will be described with reference to the drawings.

(Example)
As shown in FIGS. 1 and 2, the vehicle slope lock device 1 of the embodiment (hereinafter, simply referred to as “lock device 1”) is an example of a specific embodiment of the vehicle slope lock device of the present invention. The lock device 1 is provided in the vehicle slope lock system 9 (hereinafter, simply referred to as “lock system 9”) together with the base 8, the slope 5, and the release operation unit 6. The lock system 9 is an example of a specific embodiment of the vehicle slope lock system of the present invention.

In this embodiment, the lock system 9 is applied to a welfare vehicle C1 capable of carrying in and out a wheelchair or the like. The welfare vehicle C1 is an example of the "vehicle" of the present invention. As shown in FIG. 1, the base 8 constitutes a part of the vehicle body C2 of the welfare vehicle C1 on the rear opening C3 side, and has an upper surface 8A and a rear end surface 8B. The upper surface 8A is a flat surface that gently slopes downward toward the rear opening C3. The rear end surface 8B is a flat surface extending substantially vertically downward from the edge of the upper surface 8A on the rear opening C3 side.

In the following description, the rear opening C3 side of the welfare vehicle C1, that is, the left side of the paper surface of FIG. 1 is defined as the rear, and the left side surface side of the welfare vehicle C1, that is, the back side of the paper surface of FIG. 1 is defined as the left side. Then, the front-back, left-right, and up-down directions shown in each of the drawings after FIG. 2 are all displayed corresponding to FIG.

<Overall configuration of lock system>
As shown in FIGS. 1 and 2, in the locking system 9, the substrate 8 has a first wall 81 and a second wall 82 facing each other in the left-right direction. The first wall 81 and the second wall 82 project upward from a position adjacent to the rear end edge of the upper surface 8A of the substrate 8 and extend in the front-rear direction.

In this embodiment, the wheelchair or the like is carried into the upper surface 8A of the base 8 via the rear opening C3 of the welfare vehicle C1, and the wheelchair or the like in the welfare vehicle C1 is carried into the welfare vehicle C1 via the rear opening C3. A case where the vehicle is carried out to the outside will be described. The first wall 81 and the second wall 82 partition a gate 8G for carrying in and out a wheelchair or the like.

The slope 5 is a substantially rectangular flat plate member. A pair of swinging shafts 5S and 5S centered on the axis X5 are provided on the left and right side surfaces of the slope 5. The axial center X5 extends in the left-right direction at a position slightly offset forward and upward from the rear end edge of the upper surface 8A of the substrate 8. Both swing shafts 5S and 5S are cylindrical shafts that project so as to be separated from each other in the left-right direction. The left swing shaft 5S is swingably supported by the lower end of the first wall 81. The swing shaft 5S on the right side is swingably supported by the lower end portion of the second wall 82. In this way, the slope 5 is swingably supported around the axis X5 by the first wall 81 and the second wall 82 of the substrate 8.

The position P1 of the slope 5 shown by the solid line in FIG. 1 is the holding position. While the slope 5 is in the holding position P1, it stands up substantially perpendicular to the axis X5 and closes the gate 8G. The position of the slope 5 shown in FIG. 2 and the position of the slope 5 shown in FIG. 3 are also holding positions P1.

The position P2 of the slope 5 shown by the alternate long and short dash line in FIG. 1 is the unfolded position. The slope 5 extends backward from the axis X5 while being at the deployment position P2. In this state, the slope 5 opens the gate 8G and projects like a cantilever behind the rear end surface 8B of the substrate 8. Then, by pulling out the drawer portion 5P built in the slope 5 backward, the rear end of the drawer portion 5P touches the ground. As a result, when the wheelchair or the like is carried in or out via the gate 8G, the wheelchair or the like can be suitably transferred by using the slope 5 at the deployment position P2.

The position P3 of the slope 5 shown by the alternate long and short dash line in FIG. 1 is the accommodation position. The slope 5 extends forward from the axis X5 while in the accommodation position P3. In this state, the slope 5 opens the gate 8G and overlaps the upper surface 8A of the substrate 8. As a result, when the baggage or the like is carried in and out via the gate 8G, the slope 5 at the accommodation position P3 is unlikely to interfere with the loading and unloading of the baggage and the like.

The slope 5 swings forward from the deployment position P2, passes through the holding position P1, and can reach the accommodation position P3. Further, the slope 5 swings backward from the accommodation position P3, passes through the holding position P1, and can reach the deployment position P2.

As shown in FIGS. 1 and 2, the locking device 1 is provided between the upper end of the first wall 81 of the base 8 and the end of the left side surface of the slope 5 far from the axis X5, and the second of the base 8. One is provided between the upper end of the wall 82 and the end far from the axis X5 on the right side surface of the slope 5.

The release operation unit 6 is arranged on the rear end surface 8B of the substrate 8 and is located below the first wall 81. The release operation unit 6 has an operation lever 6A that projects rearwardly from the rear end surface 8B of the base 8. The release operation unit 6 is connected to the left and right lock devices 1 and 1 via a transmission cable 6C.

While the release operation unit 6 is not operated, the left and right lock devices 1 and 1 hold the slope 5 that swings forward from the deployment position P2 and reaches the holding position P1 at the holding position P1 and also holds the accommodation position. The slope 5 that swings backward from P3 and reaches the holding position P1 is held at the holding position P1. The specific configuration of the lock device 1 will be described later.

When the operation lever 6A of the release operation unit 6 is operated by an operator who carries in and out a wheelchair or the like, the operation is transmitted to the left and right lock devices 1 and 1 via the transmission cable 6C. As a result, the left and right locking devices 1 and 1 do not hold the slope 5 at the holding position P1, so that the slope 5 can swing from the holding position P1 to the deployment position P2 or the accommodation position P3.

In this way, in the lock system 9 of the embodiment, the operator appropriately operates the release operation unit 6 to swing the slope 5 to the deployment position P2, the holding position P1, or the accommodation position P3, so that the wheelchair or the like can be carried in and out. It is preferably feasible.

<Specific configuration of locking device>

When the lock device 1 on the left side is used as a reference, the forward direction in which the slope 5 swings from the deployment position P2 and passes through the holding position P1 is an example of the "first direction" of the present invention, and the slope 5 is accommodated. The backward direction that swings from the position P3 and passes through the holding position P1 is an example of the "second direction" of the present invention.

When the locking device 1 on the right side is used as a reference, the opposite is true, and the forward direction in which the slope 5 swings from the deployment position P2 and passes through the holding position P1 is the "second direction" of the present invention. As an example, the backward direction in which the slope 5 swings from the accommodation position P3 and passes through the holding position P1 is an example of the "first direction" of the present invention.
