The length of the proximal end flat plate portion 22 is set to be larger than that of the distal end flat plate portion 21.
The base end portion of the base end side flat plate portion 22 is supported by a support base 15 (see FIG. 2 and the like), and the support base 15 is hinged to the body panel 12 constituting the lower side of the door opening H of the vehicle C. 17 is connected in a state of being vertically rotatable.
Here, the support base 15 is covered with a decoration plate 15e, and the decoration is in a state in which the slope plate main body portion 20 stands up to a storage position (see FIG. 3) where the slope plate main body portion 20 tilts forward and is stored in the vehicle interior. As shown in FIG. 1, the plate 15 e is continuous with the design surface of the rear bumper 13.

<About the slope plate deployment mechanism 30>
The slope plate main body 20 is configured to be developed by a slope plate deployment mechanism 30.
The slope plate unfolding mechanism 30 moves the distal side flat plate portion 21 in the process in which the proximal side flat plate portion 22 of the slope plate main body portion 20 rotates downward from an upright position (not shown) to a backward lying position (see FIG. 4). This is a mechanism for developing the base end side flat plate portion 22. As shown in FIG. 3 and the like, the slope plate unfolding mechanism 30 includes a wire 32 passed through the base end side flat plate portion 22 and the tip end side flat plate portion 21 of the slope plate main body portion 20, the base end side flat plate portion 22 and the tip end.

Further, the other end side of the wire 32 is connected to a second retaining metal fitting 38 provided in the middle of the distal end side flat plate portion 21.

As shown in FIG. 3, the first retaining bracket 36 is located in the immediate vicinity of the base end side flat plate portion 22 of the slope plate main body portion 20 held in the retracted storage position on the extension line of the base end side flat plate portion 22. Is positioned. Then, the position of the first retaining bracket 36 is shifted forward from the position of the hinge mechanism 17 that is the rotation center of the slope plate body 20.
For this reason, while the base end side flat plate portion 22 of the slope plate main body portion 20 rotates backward from the forward tilted storage position to the upright position (not shown) around the hinge mechanism 17, The proximal end flat plate portion 22 is hardly separated and the distal end flat plate portion 21 is not pulled by the wire 32. Therefore, the distal end side flat plate portion 21 of the slope plate main body portion 20 is held in a state of being folded with respect to the proximal end side flat plate portion 22.
However, when the proximal side flat plate portion 22 of the slope plate main body portion 20 is rotated downward from the upright position toward the backward lying position, the proximal end flat plate portion 22 is gradually moved from the first retaining bracket 36 as shown in FIG. To come back backwards. Thereby, the distal end side flat plate portion 21 of the slope plate main body portion 20 is gradually pulled by the wire 32 and rotated upward with respect to the proximal end side flat plate portion 22 so as to be unfolded.
Further, when the base end side flat plate portion 22 of the slope plate main body portion 20 gradually turns upward from the state shown in FIG. 4, the first retaining metal fitting 38 and the base end side flat plate portion 22 gradually approach each other, and the wire 32. Is loosened, and the distal end side flat plate portion 21 rotates by its own weight in a direction in which it is folded with respect to the proximal end side flat plate portion 22.

<About the slope plate rotation mechanism 40>
The slope plate rotating mechanism 40 is a mechanism for rotating the proximal end side flat plate portion 22 of the slope plate main body portion 20 between the storage position and the lying down position. As shown in FIGS. 3 and 4, the slope plate rotation mechanism 40 is a link that connects the armed gear 42, the arm portion 42 a of the armed gear 42, and the base end side flat plate portion 22 of the slope plate main body portion 20. 43, a motor gear 45 that rotates the gear 42 with arm, and a motor 46 that rotates the motor gear 45.
The arm-equipped gear 42 includes a disk-shaped gear portion 42w and an arm portion 42a projecting radially outward from the gear portion 42w, and a rotating mechanism with the central shaft 42j of the gear portion 42w being horizontal. It is rotatably supported by a bearing of a gantry (not shown). Here, the rotation mechanism mount is fixed inside the door opening H of the vehicle C.
Further, a motor 46 is fixed to the rotation mechanism base, and a motor gear 45 of the motor 46 is engaged with a gear portion 42 w of the gear 42 with arm. The distal end portion of the arm portion 42 a of the gear 42 with the arm and the position near the rotation center of the base plate portion 22 of the slope plate main body portion 20 are connected by a link 43.

With the above configuration, as shown in FIG. 3, when the motor 46 rotates in the forward rotation direction and the arm-equipped gear 42 rotates to the right from the state in which the slope plate body 20 is in the retracted position, the tip of the arm portion 42a becomes the gear portion. The base plate side portion 22 of the slope plate main body 20 and the tip side flat plate portion 21 folded over the base end side flat plate portion 22 are moved backward to an upright position (not shown). To turn. When the arm-equipped gear 42 continues to rotate rightward from this state, the distal end of the arm portion 42a moves rearward along the outer periphery of the gear portion 42w, so that the link 43 moves the proximal end side flat plate portion 22 of the slope plate main body portion 20. Push to gradually fall from the upright position to the backward position. Thereby, the front end side flat plate portion 21 of the slope plate main body portion 20 expands with respect to the base end side flat plate portion 22 as described above, and the front end side flat plate portion 21 and the base end of the slope plate main body portion 20 in the lying down position. As shown in FIG. 4, the side flat plate portion 22 is spanned between the door opening H of the one-box vehicle C and the ground.
As shown in FIG. 4, when the motor 46 rotates in the reverse direction from the state in which the slope plate main body portion 20 is deployed and the arm gear 42 rotates counterclockwise, the tip of the arm portion 42a is the outer periphery of the gear portion 42w. , The link 43 gradually pulls and erects the proximal side flat plate portion 22 of the slope plate main body portion 20.

<About the storage and holding mechanism 50>
The storage and holding mechanism 50 is configured so that the distal-side flat plate portion 21 that is folded over the proximal-side flat plate portion 22 does not rattle in a state where the proximal-side flat plate portion 22 of the slope plate main body portion 20 stands up to the retracted storage position. This is a mechanism that is held by the base end side flat plate portion 22.
As shown in FIGS. 3 and 4, the storage and holding mechanism 50 is provided on the back side of the proximal side flat plate part 22 and the engaged part 52 provided on the back side of the distal end side flat plate part 21. It is comprised from the engaging part 55 which can be engaged with the joint part 52. FIG.
As shown in FIG. 5, the engaged portion 52 of the storage and holding mechanism 50 is a thick plate formed in a substantially bowl shape, and includes a bracket portion 53 that is fixed to the proximal side flat plate portion 22, and a bracket portion 53. And a protruding main body 54. The heel body 54 is formed in a substantially rhombus shape by upper and lower chevron portions 54m formed symmetrically with respect to the center line L. A hook inclined surface 54k on which a hook portion 56 (described later) of the engaging portion 55 is hung is provided on the slope of the mountain portion 54m located on the bracket portion 53 side. In addition, a guide inclined surface 54e that is continuous with the hanging inclined surface 54k through the top is provided on the inclined surface located on the tip side of the mountain-shaped portion 54m.
Here, the inclination angle θ1 with respect to the center line L of the guide inclined surface 54e is set to a value sufficiently smaller than the inclination angle θ2 with respect to the center line L of the hanging inclined surface 54k.

As shown in FIG. 5, the engaging portion 55 of the storage and holding mechanism 50 is a leaf spring housed in a rectangular recess 21 h on the back side of the distal end side flat plate portion 21, and is formed in a substantially lateral U shape on the side surface. A hook portion 56 configured to be able to engage with the chevron portion 54m of the engaged portion 52 is provided at both upper and lower end portions of the engaging portion 55. Further, the portion excluding the hook portion 56 of the engaging portion 55 is a U-shaped fixing portion 57 that is fixed to the rectangular concave portion 21 h of the distal end side flat plate portion 21.
Here, the interval between the upper and lower hook portions 56 in the engaging portion 55 is set to a value sufficiently smaller than the width dimension (vertical dimension) of the flange main body portion 54 of the engaged portion 52. Further, as shown in FIG. 6, the depth dimension of the engaging portion 55 is set to a value sufficiently larger than the protruding dimension of the flange main body portion 54 of the engaged portion 52.

With the above configuration, when the base end side flat plate portion 22 of the slope plate main body portion 20 is pivoted upward to an upright position (not shown), as shown in FIG. The leading end portions of the upper and lower hook portions 56 in the engaging portion 55 come into contact with the guide inclined surface 54e. And if the base end side flat plate part 22 of the slope board main-body part 20 rotates to the storage position of the forward inclination from this state, the collar main-body part 54 of the to-be-engaged part 52 will be relative by the load by the weight of the front end side flat plate part 21. Thus, the hook portion 56 is pushed between the hook portions 56 of the engaging portion 55, and the hook portion 56 is elastically deformed in the expanding direction, and moves in the direction of the inclined surface 54k along the guide inclined surface 54e. And before the base end side flat plate part 22 of the slope plate main-body part 20 arrives at a storing position, the hook part 56 of the engaging part 55 of the front end side flat plate part 21 is the top part of the mountain-shaped part 54m of the to-be-engaged part 52. It gets over and is hung on the inclined surface 54k by a spring force (see FIG. 6).
Here, the inclination angle θ1 of the guide inclined surface 54e of the engaged portion 52 and the spring force of the hook portion 56 of the engaging portion 55 receive a load due to the weight of the distal end flat plate portion 21, and the hook portion 56 is covered. It is set to such a value that it can move from the guide inclined surface 54e of the engaging portion 52 to the position of the hanging inclined surface 54k.

Further, when the proximal end side flat plate portion 22 of the slope plate main body portion 20 rotates rearward from the upright position and the distal end side flat plate portion 21 expands with respect to the proximal end side flat plate portion 22, the unfolding force of the distal end side flat plate portion 21. Thus, the upper and lower hook portions 56 of the engaging portion 55 are elastically deformed in the expanding direction with respect to the upper and lower hanging inclined surfaces 54k of the engaged portion 52, and come off along the hanging inclined surfaces 54k. Here, the inclination angle θ2 of the hanging inclined surface 54k of the engaged portion 52 and the spring force of the hook portion 56 of the engaging portion 55 are related even when a load due to the weight of the distal end side flat plate portion 21 is applied in the releasing direction. The hook portion 56 of the joint portion 55 is set to a value that does not come off the hanging inclined surface 54k of the engaged portion 52. However, the inclination angle θ2 of the hanging inclined surface 54k of the engaged portion 52 and the spring force of the hook portion 56 of the engaging portion 55 are related when the unfolding force of the distal end side plate portion 21 is applied in the disengagement direction. The value is set such that the hook portion 56 of the joint portion 55 is disengaged from the hanging inclined surface 54k of the engaged portion 52.
The unfolding force of the tip side flat plate portion 21 is set to a value sufficiently larger than the load due to the weight of the tip side flat plate portion 21.

<About the operation of the vehicle slope device 10 according to the present embodiment>
In a state in which the slope device 10 is stored in the one-box vehicle C, that is, in a state in which the slope plate main body 20 is in the forward tilted storage position, the distal end side with respect to the base side flat plate portion 22 of the slope plate main body 20. The flat plate portion 21 is folded. The hook portion 56 of the engaging portion 55 is hung on the hanging inclined surface 54 k of the engaged portion 52 of the storage and holding mechanism 50. That is, the engaged portion 52 and the engaging portion 55 of the storage and holding mechanism 50 are engaged.
As described above, the inclination angle θ2 of the hanging inclined surface 54k of the engaged portion 52 and the spring force of the hook portion 56 of the engaging portion 55 are applied when the load due to the weight of the tip side flat plate portion 21 is applied in the direction of release. However, the value is set so that the hook portion 56 of the engaging portion 55 does not come off the hanging inclined surface 54k of the engaged portion 52. For this reason, for example, even when vibration is applied to the slope plate main body 20 during traveling of the vehicle, the distal end side flat plate portion 21 of the slope plate main body portion 20 does not rattle with respect to the base end side flat plate portion 22. .
Next, when the motor 46 of the slope plate rotating mechanism 40 is driven and the arm-equipped gear 42 rotates rightward in FIG. 3, it is pushed by the link 43, and the proximal side flat plate portion 22 and the distal end side of the slope plate main body portion 20. In a state in which the flat plate portion 21 is folded, the plate 21 is rotated backward from a forward tilted storage position to an upright position (not shown). Further, when the arm-equipped gear 42 continues to rotate clockwise from this state, the link 43 causes the proximal end side flat plate portion 22 of the slope plate main body portion 20 to gradually rotate downward from the upright position. As a result, the wire 32 of the slope plate unfolding mechanism 30 gradually pulls the tip side flat plate portion 21 of the slope plate main body portion 20, and a developing force is applied to the tip side flat plate portion 21.

  Here, the inclination angle θ2 of the hooking inclined surface 54k of the engaged portion 52 in the storage and holding mechanism 50 and the spring force of the hook portion 56 of the engaging portion 55 are applied in the disengagement direction by the unfolding force of the distal end side flat plate portion 21. In such a case, the hook portion 56 of the engaging portion 55 is set to such a value as to be disengaged from the hanging inclined surface 54k of the engaged portion 52. For this reason, the engagement between the engaging portion 55 of the storage holding mechanism 50 and the engaged portion 52 is released by the deployment force, and the distal-side flat plate portion 21 with respect to the proximal-side flat plate portion 22 of the slope plate main body portion 20. Will begin to expand. Then, as shown in FIG. 4, the base end side flat plate portion 22 of the slope plate main body portion 20 rotates downward to the lying down position, so that the tip end side flat plate portion 21 is about 180 with respect to the base end side flat plate portion 22. The slope plate body 20 is spread between the door opening H of the one-box vehicle C and the ground.

  When the armed gear 42 rotates counterclockwise by driving the motor 46 of the slope plate rotation mechanism 40, the base plate 22 on the base end side of the slope plate main body 20 is rotated upward from the lying position by being pulled by the link 43. . As a result, the first retaining member 38 of the slope plate unfolding mechanism 30 and the proximal end side flat plate portion 22 of the slope plate main body portion 20 gradually approach each other, the wire 32 is loosened, and the distal end side flat plate portion 21 is based on its own weight. It rotates in the direction folded with respect to the end side flat plate part 22. In this manner, the distal-side flat plate portion 21 is folded over the proximal-side flat plate portion 22 in a state where the proximal-side flat plate portion 22 of the slope plate main body portion 20 stands up to the upright position. Then, in the process in which the base end side flat plate portion 22 of the slope plate main body portion 20 is tilted forward from the upright position to the retracted position, the flange main body portion 54 of the engaged portion 52 is relatively moved by the load due to the weight of the front end side flat plate portion 21. The engagement portion 55 and the engaged portion 52 are engaged with each other by being pushed between the hook portions 56 of the engagement portion 55.

<Advantages of the vehicle slope device 10 according to the present embodiment>
According to the vehicle slope device 10 according to the present embodiment, the engaging portion 55 depends on the weight of the distal flat plate portion 21 when the distal flat plate portion 21 of the slope plate main body portion 20 is folded on the proximal flat plate portion 22. It is configured to engage with the engaged portion 52 with a load. For this reason, by standing the base end side flat plate portion 22 and storing it in the vehicle interior, the front end side flat plate portion 21 folded over the base end side flat plate portion 22 can be held in the storage position. Therefore, it is not necessary to operate the lock mechanism or the like after the front end side flat plate portion 21 is stored in the storage position.
Further, the engaging portion 55 is engaged by the unfolding force of the distal end side flat plate portion 21 that is larger than the load due to the weight of the distal end side flat plate portion 21 when the distal end side flat plate portion 21 expands with respect to the proximal end side flat plate portion 22. It is comprised so that it may remove | deviate from the joint part 52. FIG. For this reason, in the state where the base end side flat plate portion 22 and the distal end side flat plate portion 21 are stored in the vehicle interior, the engagement between the engaging portion 55 and the engaged portion 52 is released due to vibration or the like during vehicle travel. Therefore, the distal end side flat plate portion 21 does not rattle with respect to the proximal end side flat plate portion 22. Furthermore, it is not necessary to release the lock by operating a lock mechanism or the like when the front end side flat plate portion 21 is expanded with respect to the base end side flat plate portion 22.
For this reason, the operation of the slope device 10 is not complicated.

Moreover, the engaging part 55 and the to-be-engaged part 52 engage by changing the inclination angle of the guide inclined surface 54e in the mountain-shaped part 54m of the hook main body part 54 of the to-be-engaged part 52, and the hanging inclined surface 54k. Since the force at the time and the force when the engaging portion 55 is disengaged from the engaged portion 52 can be changed, the configuration is simplified.
Further, since the slope plate unfolding mechanism 30 is composed of the wire 32 and the reel portion 34 on which the wire 32 is hung, the structure for unfolding the distal end side flat plate portion 21 with respect to the proximal end side flat plate portion 22 is simple. become.
