  However, the above-described conventional slope forming apparatus has the following problems. In other words, since the slope plate remains integrally attached to the lower door, it is necessary to increase the length of the slope plate in order to loosen the slope angle without changing the installation height position where the lower door is installed. There is. However, when the length of the slope plate is increased, there is a problem that the height of the slope plate gives a feeling of pressure to the occupant when the slope plate stands up together with the lower door in the vehicle interior. In addition, it has been pointed out that it is difficult to take in and out the luggage from the opening when the slope plate is standing in the vehicle.

The present invention has been made in view of the above-described problems, and the problem to be solved by the present invention is to ensure the length of the slope as long as possible in the use state and to reduce the height of the slope plate in the stored state. It is to be.
Furthermore, in addition to the above-mentioned problems, it is to facilitate the loading and unloading of luggage from the opening in the stored state.

In order to solve the above-mentioned problems, the present invention takes the following means.
First, according to the first aspect of the present invention, when the upper and lower doors are arranged so as to be pivotable in the vertical direction with the upper and lower ends as pivotal fulcrums with respect to the opening formed in the vehicle, and the lower door is closed. A slope plate that is pivotably coupled to the lower door so as to stand up in the vehicle and to be inclined between the lower edge of the opening and the road surface when the lower door is opened. A slope forming device for a vehicle, wherein the slope plate overlaps with the inner side surface of the lower door with respect to the lower door, and the lower door is positioned closer to the leading end of the lower door than the retracted position. It is connected so that it can move between the vehicle inner side surface and the advance position which forms the continuous slope surface.

In the first aspect of the present invention, the slope plate is located at the front end side of the lower door at the advance position where the slope surface is formed, and forms a slope surface continuous with the vehicle interior side surface of the lower door. That is, since the inner side surface of the vehicle is used as the slope surface, the length of the slope can be secured longer.
Note that the slope plate overlaps the inner side surface of the lower door at the retracted position of the slope plate. For this reason, even when the length of the slope is set to the required predetermined length, the length of the slope plate can be shortened by the length of the side surface of the vehicle, and the height of the slope plate in the retracted state can be reduced. it can.

  Next, a second invention is characterized in that in the vehicle slope forming apparatus according to the first invention described above, the lower door and the slope plate are connected via a parallel link mechanism.

  In the second invention, the slope plate is connected to the lower door by the parallel link mechanism. Thereby, the movement of the slope plate with respect to the lower door between the retracted position and the advanced position is mechanically performed more reliably.

  Next, the third invention is such that one link of the parallel link mechanism is separable from the lower door or the slope plate, and the one link is separated when the lower door is closed. The slope plate can fall on the passenger compartment floor.

  In this 3rd invention, it is set as the structure which one link of a parallel link mechanism can isolate | separate from a lower door or a slope board, and when it isolate | separates, a slope board can be laid down on a vehicle interior floor. When the slope plate is laid down on the passenger compartment floor when the lower door is in the closed state, luggage from the opening in the retracted state can be easily carried out.

The present invention can obtain the following effects by taking the above-described means.
First, according to 1st invention, a slope board stands up in a vehicle by making a lower door into a closed state. At this time, by moving the slope plate to the retracted position, the slope plate is disposed at a position overlapping the inner side surface of the lower door, so that the height of the slope plate from the vehicle floor can be reduced, thereby The occupant's feeling of pressure can be reduced. In addition, when the lower door is opened, the slope plate is slanted between the opening and the road surface. At this time, by moving the slope plate to the advanced position, the slope plate can form a slope surface that is continuous with the vehicle interior side surface of the lower door, whereby the slope of the slope surface can be moderated.
Next, according to the second invention, the slope plate can be moved between the retracted position and the advanced position with a simple structure.
Next, according to the third invention, when the lower door is in a closed state, the slope plate can be laid down on the passenger compartment floor by separating one link of the parallel link mechanism from the lower door or the slope plate. Thus, it is possible to easily take in and out the luggage from the opening.

Embodiments of the present invention will be described below.
FIG. 1 is a side view in which the slope forming device 10 of the present embodiment is applied to the rear part of the automobile M. FIG. FIG. 2 is a side view showing a use state and a storage state of the slope forming apparatus 10 of the present embodiment. FIG. 3 is a perspective view showing an exploded state of the slope forming apparatus 10 of the present embodiment. FIG. 4 is a side view for explaining a use state of the slope forming apparatus 10 of the present embodiment. As shown in FIG. 1, the automobile M applied to the slope forming apparatus 10 of the present embodiment is a so-called hatchback automobile in which an opening K is formed in the rear part thereof. The slope forming apparatus 10 includes an upper door 4 and a lower door 2, and a slope plate 3 that forms the slope 1 in a state of being inclined between the lower edge of the opening K and the road surface G. . The opening K of the automobile M is opened and closed by the upper door 4 and the lower door 2. The upper door 4 opens and closes about 2/3 above the opening K by rotation of an upper hinge (not shown) provided at the upper edge of the opening K. As shown in FIG. 2, the lower door 2 opens and closes about 1/3 below the opening K by the rotation of the lower hinge 6 provided on the vehicle width direction frame 7 attached to the floor F. In order to open the rear part of the automobile M, the upper door 4 is opened while being lifted upward, and then the lower door 2 is pulled while being inclined in the direction of the road surface G. Thus, the opening K is largely opened, so that a disabled person can get on and off from the rear of the vehicle while riding on a wheelchair. In addition, it is possible to carry in or carry out while keeping a luggage or the like on a cart or a cart.

  As shown in FIG. 3, the lower door 2 has a substantially rectangular parallelepiped shape that is horizontally long in the vehicle width direction. Support shafts 53 and 53 for connecting the links 51 constituting the parallel link mechanism 5 (see FIG. 2) are provided above both side surfaces of the lower door 2. Screw holes 22 and 22 for fixing the rear bumper 8 with bolts are provided at positions slightly below from here. In addition, a latch mechanism (not shown) of the upper door 4 when the opening K is closed is provided on the side surface on the near side of the lower door 2 as viewed in FIG. ) And a striker 23 for locking the upper door 4 is provided. Moreover, when the slope 1 is formed, the vehicle interior side surface 1a (the upper surface in FIG. 3) of the lower door 2 constitutes a part of the slope surface. The lower door 2 is provided with a locking device (not shown) for locking to the automobile M, and the lower door 2 can be fixed in a closed state by this locking device.

  The rear bumper 8 is formed larger than the lower side surface of the lower door 2 as viewed in FIG. 3 (the side surface of the vehicle outer side in the retracted state where the lower door 2 stands in the vehicle interior). On both side surfaces of the rear bumper 8 in the vehicle width direction, mounting holes 81 and 81 for fixing the lower door 2 with bolts using the screw holes 22 are provided. The rear bumper 8 is fixed in a state of being fitted into the lower door 2 so as to cover the lower side surface of the lower door 2. Thereby, the lower periphery of the motor vehicle M can be protected when the lower door 2 is closed.

  The slope plate 3 includes a main body slope plate 31 and an extended slope plate 30. The main body slope plate 31 is provided with slide rails 32 on both sides of the main body slope plate 31 so that an extended slope plate 30 described later can slide. Both slide rails 32, 32 are formed in a U-shaped cross section. Support shafts 33, 33 for connecting to the link 51 are provided on the outer side surface of the slide rail 32. Moreover, when the slope 1 is formed, the upper surface 1b of the main body slope plate 31 constitutes a part of the slope surface.

  The length of the extension slope plate 30 in the vehicle width direction (in the upper right oblique direction as viewed in FIG. 3) is formed slightly shorter than the length of the main body slope plate 31. Sliders 30 a and 30 a are provided on both sides of the extension slope plate 30, and the slider 30 a is inserted inside the slide rail 3 so that the extension slope plate 30 can slide with respect to the main body slope plate 31. As a result, when the extended slope plate 30 is slid in a direction overlapping the main body slope plate 31, the slope plate 3 can be reduced to a reduced state. On the other hand, when the extended slope plate 30 is slid in the direction in which the extended slope plate 30 is pulled out from the main body slope plate 31, the slope plate 3 can be in an extended state having a long length. The sliding movement in each direction can be easily performed by holding the handle 30b provided at the distal end portion of the extension slope plate 30. Further, when the slope 1 is formed, the upper surface 1c of the extension slope 30 constitutes a part of the slope surface.

  Further, when a protrusion (not shown) is provided on the inside of the side surface in the vehicle width direction of the main body slope plate 31 and the extension slope plate 30, and when the extension slope plate 30 is slid in the pulling direction, it is pulled out to a predetermined location. A slide stop mechanism (not shown) for stopping the slide is provided. Thereby, the extension slope board 30 does not come off from the main body slope board 31.

  The lower door 2 and the slope plate 3 are connected by a parallel link mechanism 5. The parallel link mechanism 5 includes a pair of links 51 arranged in parallel. Each link 51 has one end rotatably connected to the support shaft 53 of the lower door 2 and the other end connected to the support shaft 33 of the main body slope plate 31 so as to be rotatable. Then, the slope plate 3 is maintained in a state parallel to the lower door 2 by the rotation of each link 51, and the retracted position overlaps with the vehicle interior side surface 1a of the lower door 2, and the tip of the lower door 2 more than the retracted position. The upper surfaces 1b and 1c of the lower door 2 are located between the advancing positions where they form a slope surface continuous with the vehicle interior side surface 1a.

Next, the operation of the slope forming device 10 will be described.
In FIG. 2, the slope forming device 10 in the retracted state is indicated by a two-dot chain line, and the slope forming device 10 in the used state is indicated by a solid line. When the slope forming device 10 is in the retracted state, the lower door 2 and the upper door 4 are in the closed position, the slope plate 3 is in the retracted position in the contracted state, and stands up in the vehicle along the inner side surface 1a of the lower door 2. is doing. In order to put the slope forming device 10 into a use state, the upper door 4 is opened while being pulled upward from this state. Next, the lower door 2 fixed to the lower hinge 6 is rotated in the road surface G direction with the rotation shaft 61 as a rotation fulcrum. Accordingly, the slope plate 3 connected to the lower door 2 by the parallel link mechanism 5 is inclined in the road surface G direction. A stopper 9 is provided on the lower side of the lower hinge 6 and abuts against the lower door 2 to take a load applied thereto (see FIG. 4). The stopper 9 is preferably a rubber member that easily absorbs an impact load when the lower door 2 rotates. Next, the slope plate 3 is moved to the rearward (rightward) advance position as seen in FIG. The slope plate 3 has a lower end portion of the main body slope plate 31 (lower end portion of the left corner of the slope plate 3 as viewed in FIG. 2) and an upper end portion of the lower door 2 (lower end portion of the right corner of the lower door 2 as viewed in FIG. 2). By abutting, it is held at the advanced position. Next, the extended slope plate 30 is pulled out from the main body slope plate 31, and the extended slope plate 30 is brought into contact with the road surface G. As a result, the slope forming device 10 is put into use and the slope 1 is formed. In this state, the vehicle interior side surface 1a of the lower door 2, the upper surface 1b of the main body slope plate 31, and the upper surface 1c of the extension slope plate 30 are arranged obliquely in order toward the rear of the vehicle, forming a connected slope surface. is doing. Thereby, a disabled person can get on and off smoothly from the rear of the automobile while riding in a wheelchair. Note that the position of contact with the road surface G can be finely adjusted by inserting and removing the extended slope plate 30 from the main body slope plate 31. In addition, what is necessary is just to perform operation contrary to the above in order to make the slope formation apparatus 10 into a retracted state.

  As described above, according to the slope forming apparatus 10 in the present embodiment, when in the retracted state, the slope plate 3 stands up in the vehicle, but the slope plate 3 overlaps the vehicle interior side surface 1a of the lower door 2. Since the slope plate 3 is in the retracted position and the main body slope plate 31 and the extended slope plate 30 overlap each other, the height from the vehicle floor F to the upper end of the slope plate 3 is low. . As a result, the occupant's feeling of pressure can be reduced. On the other hand, when in use, the slope plate 3 is in an extended state in which the extended slope plate 30 is pulled out from the main body slope plate 31, and the slope plate 3 is in the advanced position moved to the tip side of the lower door 2. Since it is positioned, a long slope 1 is formed. Thereby, the slope of the slope surface can be made gentle.

FIG. 5 shows another embodiment. A slope forming device in a normal retracted state is indicated by a solid line, and a state where the slope plate 3 is laid down toward the vehicle interior is indicated by a two-dot chain line.
This embodiment is different from the above-described embodiment only in the connection structure between one link of the parallel link mechanism 5 and the lower door 2. The parallel link mechanism 5 is provided on both the left and right sides of the lower door 2. Each parallel link mechanism 5, 5 includes an upper link arm 51a and a lower link arm 51b. One end of each of the link arms 51a and 51b is supported so as to be rotatable about pivots 53a and 53b provided on the sides of the lower door 2, respectively. A cutout portion 54 is formed in a portion where the link arm 51a is connected to the lower door 2, and the link arm 51a is detachably attached to the support shaft 53a through the cutout portion 54. The other ends of the link arms 51a and 51b are supported so as to be rotatable about pivots 53c and 53d provided on the side portions of the lower door 2, respectively.

  In a state in which the link arm 51a is attached to the support shaft 53a, the link arm 51a can rotate about the support shaft 53a as a rotation fulcrum. On the other hand, when the operation lever 52 formed to extend outward from the cutout portion 54 of the link arm 51a is lifted from this state in the arrow direction A1, the link arm 51a is detached from the support shaft 53a. Then, when the slope plate 3 rotates through the support shaft 53d and is tilted in the arrow direction A2, the slope plate 3 is in a state of being laid down toward the vehicle inner side indicated by a two-dot chain line. This facilitates loading and unloading of luggage from the opening K. Further, when the slope plate 3 is laid down on the vehicle inner side, the driver's rear view is improved.

The present invention is not limited to the configuration of the above embodiment, and can be implemented in various other forms.
In the said embodiment, although the example connected with the lower door 2, the slope board 2, and the parallel link mechanism 5 was shown, it does not restrict to this. For example, the slope plate 3 may be slidably connected to the lower door 2.
In the present embodiment, an example in which the extension slope 30 is provided in order to ensure a longer length of the slope 1 has been described. However, if the length of the slope 1 can be sufficiently secured, the extension slope 30 may not be provided. .
Furthermore, although the example applied to the rear part of the automobile has been described in the present embodiment, it may be applied to the side part of the automobile as long as it can be installed. Moreover, although this embodiment demonstrated the example applied to the motor vehicle, you may apply not only to a motor vehicle but to the opening part of a rail vehicle.
