The front end portions of the left and right second hinge pieces 5b are connected to the left and right first hinge pieces 5a and 5a so as to be rotatable in the vertical direction. Here, when the first slope member 1 and the second slope member 2 are in parallel, the tips of the left and right hinge attachment portions 1b and 1b butt the tips of the left and right hinge attachment portions 2b and 2b. It becomes a state. Therefore, the range in which the first slope member 1 and the second slope member 2 can rotate relative to each other is limited to about 180 °. The second slope member 2 is substantially perpendicular to the floor of the vehicle compartment when in the stored state. As shown in FIGS. 1 and 5, the tip 2 a of the second slope member 2 is formed with an inclined surface 2 g which is inclined toward the back surface 2 f.
In the stored state, the distal end 2 a of the second slope member 2 is disposed at a position higher than the proximal end 1 a of the first slope member 1. The height of the tip 2a is set to be lower than the height of the handwheel of the wheelchair housed in front of the vehicle slope device.

  The base end 2 e of the second slope member 2 is vertically rotatably supported by the tip end 7 a of the slope support member 7 via the plurality of forward hinges 6. The slope support member 7 is provided substantially perpendicularly to the floor in the vehicle compartment. The second slope member 2 is pivoted approximately 90 ° between the stored state and the forwardly folded state (see FIG. 6) laid on the floor in the vehicle compartment by the forwardly folded hinge 6. In addition, when in the forward tilt state, the surface 1c of the first slope member 1 is substantially parallel to the road surface. The slope support member 7 has its base end 7 b rotatably attached to the opening edge 9 of the rear opening of the vehicle via a plurality of deployment hinges 8 in the vertical direction. The slope support member 7 can be pivoted between the storage state and the use state by the deployment hinge 8. In the rear opening, as shown in FIG. 2, the tailgate 10 is vertically pivotable below the back door. The rear opening is closed by engagement of the lower end of the back door and the upper end of the tailgate 10. In the vicinity of the rear opening, an unlocking lever 10a for unlocking the tailgate 10 is attached. The tailgate 10 is connected to the slope support member 7 via a link bar 11. Therefore, the tailgate 10 and the slope support member 7 rotate in the same direction in conjunction with one of the rotation operations.

  A first lock mechanism 12 is provided on the first slope member 1 and the second slope member 2. The first lock mechanism 12 has a striker 12 a provided on the right flange 2 d of the second slope member 2 and a lock 12 b provided on the right flange 1 d of the first slope member 1. When the first lock mechanism 12 is in the stored state, the engagement claws housed inside the lock portion 12b engage with the striker 12a, and the relative rotation of the first slope member 1 and the second slope member 2 in the deployment direction Regulate. The engagement claws are biased in a direction to engage the striker 12a. The user can unlock the first lock mechanism 12 by pulling the strap provided on the lock portion 12b against the biasing force of the engagement claw. In addition, since the engagement claw is interlocked with the lock release lever 10a of the tailgate 10, the user operates the strap or the lock release lever 10a to lock the first lock mechanism 12 and the tailgate 10 simultaneously. It can be released.

  The slope support member 7 and the second slope member 2 are provided with left and right second lock mechanisms 13.

When the second lock mechanism 13 is in the stored state, the engagement claws accommodated inside the left and right lock portions 13b, 13b engage with the strikers 13a, 13a, and the second slope member 2 is moved forward with respect to the slope support member 7. Regulate the rotation of the The engagement claws are biased in a direction to engage the striker 13a. The user can release the lock of the left and right second lock mechanisms 13 by pulling the straps provided on the left and right lock portions 13 b and 13 b against the urging force of the engagement claws.

  The third slope member 3 is formed on a substantially rectangular flat plate. The length of the third slope member 3 is set longer than the length of the gap formed between the base end 1a of the first slope member 1 and the tip 2a of the second slope member 2 in the use state . Further, the width of the third slope member 3 is set smaller than the width of the first slope member 1. The base end 3 a of the third slope member 3 is rotatably supported in the vertical direction in the vicinity of the base end 1 a of the back surface 1 f of the first slope member 1. The tip 3 b of the third slope member 3 is slidably supported on the back surface 2 f of the second slope member 2. Left and right slide rails 14, 14 are attached to the left and right ends of the back surface 2 f of the second slope member 2.

  As shown in FIGS. 3 and 5, left and right rollers 3c, 3c (see FIGS. 3 and 5) rotating on the left and right slide rails 14, 14 are attached to the tip 3b of the third slope member 3. On the back surface 2 f of the second slope member 2, left and right stoppers 15, 15, 16, 16 made of an elastic body are provided at both ends in the sliding direction of the left and right slide rails 14, 14. The right and left stoppers 15, 15 are in contact with the left and right rollers 3c, 3c immediately before being used at the time of deployment, and elastically contact with the left and right rollers 3c, 3c in the used state. The right and left stoppers 16, 16 are in contact with the left and right rollers 3c, 3c immediately before being in the stored state at the time of folding, and elastically contact with the left and right rollers 3c, 3c in the stored state. Each of the stoppers 15, 15, 16 and 16 is in contact with the back surface 1f of the first slope member 1 immediately before being in the stored state at the time of folding, and is in elastic contact with the back surface 1f in the stored state.

Next, the operation of the vehicle slope device according to the first embodiment will be described.
(while using it)
When the user pulls the strap of the first lock mechanism 12 with a predetermined force or more or operates the lock release lever 10a from the stored state shown in FIG. 2, the lock of the tailgate 10 and the first lock mechanism 12 is simultaneously released, The first slope member 1 is rotated by a predetermined angle in the deployment direction by the resilient force of each stopper 15, 15, 16, 16. Subsequently, when the user grips the steering wheel 4 and pulls the first slope member 1 toward the near side (rear side of the vehicle), the first slope member 1 and the second slope member 2 (including the slope support member 7) are deployed. Each is rotated in the direction to be deployed. The tailgate 10 connected to the slope support member 7 via the link bar 11 also rotates in the same direction as the second slope member 2. At this time, as the third slope member 3 slides the left and right slide rails 14, 14 in the direction in which the tip 3b approaches the tip 2a of the second slope member 2, the tip 3b is around the rotation center on the base end 3a side. It turns in the direction to move upward.

  When the first slope member 1 and the second slope member 2 are developed so as to be parallel to each other, the tip end portions of the first slope member 1 and the second slope member 2 are in abutment with each other, thereby further rotating Is regulated, and the use state shown in FIG. 1 is maintained. At this time, as shown in FIG. 7, the right and left rollers 3c, 3c of the third slope member 3 come into contact with the left and right stoppers 15, 15 immediately before being in use. Therefore, even when the deployment speed of the user is high, it is possible to suppress the occurrence of impact and collision noise when the first slope member 1 and the second slope member 2 butt. In the state of use, the third slope member 3 is substantially parallel to the first slope member 1 and the second slope member 2 on the back surfaces 1 f and 2 f of the first slope member 1 and the second slope member 2. The clearance between the third slope member 3 and the back surfaces 1 f and 2 f is very small, and the third slope member 3 is formed between the base end 1 a of the first slope member 1 and the tip 2 a of the second slope member 2. The gap is closed. That is, in the use state, the first slope member 1, the second slope member 2 and the third slope member 3 form an inclined surface on which the wheelchair can get on and off between the vehicle interior and the road surface. At this time, since the inclined surface 2 g is provided at the tip 2 a of the second slope member 2, it is possible to relieve the step between the second slope member 2 and the third slope member 3.

(When stored)
When the user holds the handle 4 and lifts the first slope member 1 from the unfolded state, the first slope member 1 and the second slope member 2 are respectively rotated and folded in the folding direction. At this time, as the third slope member 3 slides the left and right slide rails 14 and 14 in the direction in which the tip 3b approaches the base end 2e of the second slope member 2, the tip 3b around the rotation center on the base end 3a side. Rotates in the direction to move downward. The tailgate 10 connected to the slope support member 7 via the link bar 11 also rotates in the same direction as the second slope member 2. When the first slope member 1 and the second slope member 2 are folded so as to be substantially perpendicular to the floor in the vehicle compartment, the striker 12a of the first lock mechanism 12 is engaged with the lock portion 12b. The second slope member 2 is locked, and relative rotation is restricted. At the same time, since the tailgate 10 is fixed (locked) to the opening edge 9 of the rear opening, the rotation of the slope support member 7 is restricted, and the stored state is maintained.

  In the stored state, since the left and right rollers 3c, 3c are in elastic contact with the left and right stoppers 16, 16, rattling can be prevented. Thereby, it is possible to suppress the generation of the unpleasant rattling noise as the third slope member 3 repeats the minute swing due to the vibration of the vehicle. In the stored state, the stoppers 15, 15, 16, 16 are interposed between the back surface 1f of the first slope member 1 and the back surface 2f of the second slope member 2, so that the vehicle vibrates. As the first slope member 1 and the second slope member 2 repeat contact, it is possible to suppress the generation of unpleasant fluttering noise. Here, in the stored state, the base end 1a of the first slope member 1 and the tip 2a of the second slope member 2 are lower than the left and right hinges 5, 5 and the left and right hinge attachment portions 1b, 1b, 2b, 2b Become. Further, the left and right hinges 5, 5 and the left and right hinge attachment portions 1b, 1b, 2b, 2b are located on the left and right outer sides of the wheelchair. Therefore, even when the storage case is narrow in the front-rear direction when the wheelchair is accommodated when the steering wheel overhangs rearward of the tire of the wheelchair, the first slope member 1 and the second slope member 2 and the steering wheel and Interference can be suppressed.

(When moving ahead)
When the user pulls the straps of the left and right second lock mechanisms 13 and 13 with a predetermined force or more from the stored state, the locks of the left and right second lock mechanisms 13 and 13 are both released, and the first slope member 1 and the second slope member 2 Can be turned forward by the forward-folding hinge 6. Therefore, the user pushes down the first slope member 1 from the rear side or pulls down the second slope member 2 from the front side from the state in which the left and right third sheets 17, 17 as shown in FIG. Thus, as shown in FIG. 9, the first slope member 1 and the second slope member 2 can be advanced forward on the floor. This facilitates loading and unloading of the rear opening. Moreover, since the surface 1c of the 1st slope member 1 can be utilized as a loading platform, when the wheelchair is not mounted on a vehicle, the luggage space of the vehicle rear part can be ensured widely. Although four strikers 18 for fixing the feet of the left and right third sheets 17, 17 are provided on the floor, the base end 1a and the tip 2a of the first slope member 1 and the second slope member 2 are Each striker 18 is set to an exposed length without being covered by the first slope member 1 and the second slope member 2. Therefore, when the left and right third seats 17, 17 are returned to the use state, the passenger can be placed on the left and right third seats 17, 17 and the rear can be used as a luggage space.

[Both work simplification and interference suppression with a wheelchair]
Heretofore, as a deployment / storage structure of a vehicle slope device that enables getting on / off by a passenger's wheelchair, a double folding type, a multi-fold folding type of three or more folds, and a slide type (two stages, three stages or more multistage) are known is there. Among them, the two-fold type and the two-stage slide type are easy to deploy and store, but have the disadvantage that the height when stored in an upright state increases. When the height in the stored state is increased, there is a possibility that the wheelchair may interfere with the wheelchair when the handle is accommodated behind the tire of the wheelchair. In the case of a small car, in particular, it is difficult to secure a sufficient space for accommodating the wheelchair in the front-rear direction, so there is a possibility that the wheelchair can not be accommodated. On the other hand, in the case of the three-fold type and the multistage slide type, the height when stored in the upright state is low, but the development and storage work becomes complicated. In addition, since the multistage slide type has a tapered structure, there is a possibility that a sufficient width for getting on and off the wheelchair can not be secured particularly in the case of a small car.

On the other hand, in the slope apparatus for a vehicle according to the first embodiment, the lengths of the first slope member 1 and the second slope member 2 by the amount of the third slope member 3 are required when used. It can be shorter than the length required to form a wheelchair accessible ramp between the room and the road surface. Therefore, since the height in the storage state can be lowered, interference with a wheelchair can be suppressed. Also, since the third slope member 3 operates in conjunction with the deployment and folding operations of the first slope member 1 and the second slope member 2, the third slope member 3 is deployed and stored (folded) in the same manner as the conventional two fold type. Work can be simplified. That is, in the slope apparatus for a vehicle according to the first embodiment, based on a two-fold type consisting of the first slope member 1 and the second slope member 2, the gap between both slope members 1 and 2 is closed when used, At that time, by providing the third slope member 3 that retracts downward from the top (base end 1a, tip 2a) of both slope members 1 and 2, simplification of deployment and storage work and interference suppression with a wheelchair are achieved. It is possible to achieve both.
Further, as shown in FIG. 9, assuming the use in the front-turning state, the width of the vehicle slope device is limited by the space between the two side seats 17 and 17, so a wheelchair with multi-stage slide type is available The width of the aisle narrows, limiting the wheelchairs that can be mounted. On the other hand, in the first embodiment, by adopting the double-folding type, it is possible to secure the passage width of the wheelchair while enabling the use in the front-down state, and various wheelchairs can be mounted.

The following effects are achieved in the first embodiment.
(1) A state of use in which an inclined surface is formed between the vehicle interior and the road surface by expanding the first slope member 1 and the second slope member 2 provided rotatably at the entrance of the vehicle and mutually connected. The vehicle slope apparatus is in a storage state in which the slope members 1 and 2 are folded in a mountain fold to be stored upright in a vehicle compartment, and both slope members 1 and 2 are used when they are in use. Connecting portions for connecting both slope members 1 and 2 (left and right hinges attached to each other) at the left and right ends of the connection side end edges (the base end 1a and the tip 2a) separated from each other in the length direction Parts 1b, 1b, 2b, 2b and left and right hinges 5, 5) are provided and supported by both slope members 1, 2 and close the gap between both slope members 1, 2 in use condition and in storage condition A third slope member 3 is provided which retracts below the two connection side edges.
Therefore, the total length of the first slope member 1 and the second slope member 2 can be made shorter than the length necessary in the use state by the length of the third slope member 3. As a result, since the height in the stored state can be lowered, interference with a wheelchair can be suppressed.

(2) The third slope member 3 is rotatably supported at its base end 3 a by the first slope member 1 and is slidably supported at its tip 3 b by the second slope member 2.
Therefore, since the operation of the third slope member 3 is interlocked with the expansion and folding operations of the first slope member 1 and the second slope member 2, the development and the folding operation can be simplified to reduce the time and effort of the operation.

(3) The second slope member 2 is provided with left and right slide rails 14 and 14 for slidably supporting the tip 3b of the third slope member 3, and both end edges of the left and right slide rails 14 and 14 in the sliding direction Left and right stoppers 15, 15, 16 and 16 made of an elastic body are provided.
Therefore, the generation of unpleasant collision noise can be suppressed during deployment and folding. In addition, rattling in the stored state can be suppressed, and the generation of unpleasant fluttering noise can be suppressed.

(4) The first lock mechanism 12 is provided to restrict relative rotation of the first slope member 1 and the second slope member 2 in the direction of deployment when in the stored state.
Therefore, it is possible to suppress rattling in the stored state and to suppress the generation of unpleasant fluttering noise. Moreover, it can prevent that the 1st slope member 1 and the 2nd slope member 2 unfold.

(5) The first lock mechanism 12 is unlocked in conjunction with the unlocking of the tailgate 10 provided at the entrance.
Therefore, since it is not necessary to individually perform unlocking of the tailgate 10 and unlocking of the first locking mechanism 12 at the time of deployment, it is possible to reduce the effort of the deployment work.

(6) The first slope member 1 and the second slope member 2 can be pivoted from the stored state to the forward tilt state on the floor in the vehicle compartment.
Therefore, when the wheelchair is not placed on the vehicle, putting the first slope member 1 and the second slope member 2 in the forward-turned state facilitates loading and unloading of luggage from the rear opening, and the luggage space at the rear of the vehicle Can be secured widely.

(7) In the stored state, the left and right second lock mechanisms 13 are provided to restrict the pivoting of the first slope member 1 and the second slope member 2 in the forward tilting direction.
Therefore, when the wheelchair is accommodated, the stored state can be maintained. In addition, it is possible to prevent an unexpected advance.

Example 2
A second embodiment will now be described. Since the basic configuration is the same as that of the first embodiment, only different points will be described. FIG. 10 is a side view showing the stored state of the vehicle slope device of Example 2, and FIG. 11 is a cross-sectional view of S11-S11 in FIG.
In the second embodiment, left and right connection is made such that the first slope member 1 and the second slope member 2 are relatively rotatably connected to the left and right ends of the base end 1 a of the first slope member 1 and the tip 2 a of the second slope member 2. The parts 19, 19 are provided. The left and right connecting parts 19, 19 have the functions of the left and right hinge attachment parts 1b, 1b, 2b, 2b and the left and right hinges 5, 5 of the first embodiment, and are separately from the first slope member 1 and the second slope member 2. It is provided. In the first slope member 1 and the second slope member 2, two slot holes 20a and 20b and a hole 20c for a plunger are respectively formed. Both slot holes 20a and 20b are long holes, and are arranged in the left and right flanges 1d, 1d, 2d and 2d at predetermined intervals in the length direction. The plunger holes 20c are respectively disposed between the slot holes 20a and 20b of the left and right flanges 1d, 1d, 2d and 2d.

  The left and right connecting portions 19 and 19 respectively have two slide pins 21a and 21b, and two plunger holes 21c and 21d are respectively formed. Both slide pins 21a and 21b are provided slidably in the corresponding slot holes 20a and 20b. In the stored state, both slide pins 21a and 21b are extended from the both slot holes 20a and 20b when extending the connecting portion in which the left and right connecting portions 19 and 19 are drawn to the top (FIGS. 10A and 11A). Abuts the top edge. The overall shape at the time of extension of the connecting portion substantially matches the overall shape of the vehicle slope device of the first embodiment. On the other hand, in the stored state, both slide pins 21a and 21b are both slot holes 20a and 20b when the connecting portions are stored with the left and right connecting portions 19, 19 pulled down (FIGS. 10 (b) and 11 (b)). Abuts the lower end of the Both plunger holes 21c and 21d are disposed between the slide pins 21a and 21b. The left and right plunger holes 21c and 21c overlap the left and right plunger holes 20c and 20c in the vertical and front-back direction when extending the connecting portion, and the left and right plunger holes 21d and 21d connect the left and right plunger holes 20c and 20c when storing the connecting portion. Overlap in the direction. The left and right plungers 22, 22 are inserted into the left and right plunger holes 20c, 20c. The left and right plungers 22, 22 are inserted into the left and right plunger holes 21c, 21c at the time of extension of the connection portion, so that the state of extension of the connection portion is maintained. On the other hand, since the left and right plungers 22, 22 are inserted into the left and right plunger holes 21d, 21d when the connection portion is stored, the connection portion stored state is maintained.

The following effects are achieved in the second embodiment.
(8) The left and right connecting portions 19, 19 can slide downward in the stored state.
Thus, the overall height in the stored state can be reduced.

[Example 3]
A third embodiment will now be described. Since the basic configuration is the same as that of the first embodiment, only different points will be described. FIG. 12 is a perspective view showing a vehicle slope device according to a third embodiment.
The third embodiment is an example in which the third slope member 3 is slid parallel to the second slope member 2 as in the case of a cat-like shoji. The third slope member 3 is provided on the back surface 2 f of the second slope member 2 and is supported slidably in parallel to the second slope member 2.

  The third slope member 3 is located below the tip 2 a of the second slope member 2 by its own weight in the stored state. When the first slope member 1 and the second slope member 2 are respectively rotated in the deployment direction from the stored state, when the tip 2a of the second slope member 2 falls below the base end 2e, the third slope member 3 is under its own weight. Slide toward the first slope member 1 side. Thereby, the gap formed between the base end 1 a of the first slope member 1 and the tip end 2 a of the second slope member 2 can be closed by the third slope member 3 in the use state. Therefore, as in the first embodiment, the operation of the third slope member 3 is interlocked with the expansion and folding operations of the first slope member 1 and the second slope member 2, so the development and folding operations are simplified to save time and effort. It can be reduced.
