  Patent Document 1 describes a technique related to this vehicle attachment device. The vehicle attachment device described in Patent Document 1 is a slope device that allows an occupant or the like who uses a wheelchair to get on / off the vehicle. The slope device is composed of a body side member (tail gate portion) connected to the lower side position of the rear side opening portion of the vehicle body so as to be vertically pivotable, and a slope plate supported by the tail gate portion There is. Then, the tailgate portion and the slope plate are rotated rearward, so that the slope plate is bridged between the rear opening of the vehicle and the ground, and it becomes possible to get on and off a wheelchair or the like.

JP, 2015-3714, A

  In the slope device 100 described above, the spring force of the coil spring 105 is configured to be applied in the upper rotation direction when the slope plate 103 is rotated downward to the collapsed position. Therefore, when the slope plate 103 is in the upright position, no spring force of the coil spring 105 is generated, and a gap is generally formed between the end of the coil spring 105 and the spring receiving portion such as the slope plate 103. ing. However, if the gap size varies due to the manufacturing accuracy of the coil spring 105, no spring force is generated at the same timing when the slope plate 103 pivots downward.

  For example, when the coil spring 105 having a large gap size is used, the timing at which a spring force is generated is delayed when the slope plate 103 pivots downward. For this reason, the rotation speed at the time of the downward rotation of the slope plate 103 becomes fast, and the specification can not be satisfied. Therefore, the coil spring 105 whose gap size is larger than the reference can not be used. That is, in the slope device 100 described above, only the coil spring 105 whose clearance dimension falls within the appropriate range can be used, so the yield of the coil spring 105 is deteriorated.

  The present invention has been made to solve the above problems, and the problem to be solved by the present invention is to reduce the number of spring materials that can not be used by providing a structure in which the timing at which the spring force works does not vary.

The tip end portion of the cylindrical body 373 of the slope plate mounting bracket 37 is rotatably supported by a bearing portion 344 fixed to the cross beam portion 34 of the tail gate portion 30. As a result, the slope plate mounting bracket 37 (the slope plate main body portion 20) can be pivoted up and down around the hinge shaft (support shaft 321) of the forward hinge mechanism 35 with respect to the tail gate portion 30.

<About the lock mechanism 50 for front overturn control>
The forward fall regulating lock mechanism 50 is a mechanism that regulates (prohibits) rotation of the slope plate main body 20 in the upright position with respect to the tailgate 30 in the upright position. As shown in FIGS. 7 and 8, the lock mechanism 50 for forward fall restriction is provided on the outer periphery of the lever member 52 connected to the slope plate mounting bracket 37 of the slope plate main body 20 and the cam plate 32 of the tail gate portion 30. And a formed cam surface 54. A central portion of the lever member 52 is connected to the slope plate mounting bracket 37 so as to be rotatable by the connection pin 51. A lock pin 521 configured to be slidable along the cam surface 54 of the cam plate 32 of the tail gate portion 30 is provided at the lower portion of the lever member 52. Further, a lock spring 57 biased to press the lock pin 521 of the lever member 52 against the cam surface 54 of the cam plate 32 is connected to the upper portion of the lever member 52.

  In the cam surface 54 of the cam plate 32 of the tail gate portion 30, an upper lock groove 541 is formed in which the lock pin 521 of the lever member 52 is fitted at the upper end position of the cam surface 54. The lock pin 521 of the lever member 52 has a spring force of the lock spring 57 as the slope plate body portion 20 is rotated upward (upright) from the collapsed position on the front to the erected position with respect to the tailgate 30 in the erected position. And engage with the upper lock groove 541 of the cam surface 54. As a result, the front overturn restriction lock mechanism 50 is locked, and the slope plate main body 20 is held at the upright position. When the lever member 52 is turned right against the spring force of the lock spring 57, the lock pin 521 of the lever member 52 is disengaged from the upper lock groove 541 of the cam surface 54, and the lock mechanism 50 is locked. The state is released. As a result, the slope plate main body portion 20 can be turned downward (forwardly inclined) forward with respect to the tail gate portion 30. That is, the slope plate main body 20 corresponds to the vertical rotation member of the present invention.

<About the spring mechanism 60 for front overturning buffer>
Between the slope plate body portion 20 and the tail gate portion 30, as shown in FIG. 9 to FIG. 13, the slope plate body portion with respect to the tail gate portion 30 with the lock state of the lock mechanism 50 for forward fall restriction released. A forwardly collapsible buffer spring mechanism 60 is provided which allows the frontward rotation of the vehicle 20 to be performed gently. 9 and the like, a coil spring 63 provided between the slope plate main body 20 and the tail gate 30, an end 63 f of the coil spring 63, and a tail gate 30 (a cross beam It is comprised from the insertion member 65 inserted in the clearance gap S between the spring receiving parts 34b of part 34).

  The coil spring 63 is provided so as to surround the cylindrical body 373 of the slope plate mounting bracket 37 of the slope plate main body 20, and one end portion 63e of the coil spring 63 is, as shown in FIG. Is inserted into the spring receiving hole 37a. Therefore, as shown in FIGS. 12 and 13, one end 63e of the coil spring 63 rotates left with the slope plate main body 20 when the slope plate main body 20 rotates downward (left rotation) forward. It will be. Further, the other end 63 f of the coil spring 63 is configured to be received by a spring receiving portion 34 b provided in the cross beam portion 34 of the tail gate portion 30. Further, as shown in FIG. 9 and the like, the other end 63 f of the coil spring 63 is pressed from the opposite side of the spring receiving portion 34 b by a pressing member 344 p provided on the bearing portion 344 of the forward tilting hinge mechanism 35.

  When the slope plate main body portion 20 rotates downward (left rotation) forward from the standing position, the coil spring 63 rotates around the axis by rotating one end 63e of the coil spring 63 left with the slope plate main body portion 20. Twisting generates a spring force in the upper rotation direction (right rotation direction). For this reason, in the state where the slope plate main body portion 20 is in the upright position, the coil spring 63 is not twisted around the axial center, and a spring force is not generated. Therefore, as shown in FIG. 12, generally between the other end 63f of the coil spring 63 and the spring receiving portion 34b of the tail gate portion 30 (lateral beam portion 34) when the slope plate main body portion 20 is in the upright position. Thus, the gap S is formed.

  The dimension of the gap S changes due to the variation in the manufacturing accuracy of the coil spring 63. For example, when the coil spring 63 having a large gap size is used, when the slope plate main body portion 20 is rotated downward (leftward rotation) forward, the timing at which a spring force is generated is delayed. For this reason, the rotation speed at the time of the slope plate main body portion 20 rotating downward (left rotation) forward becomes faster. In order to prevent this, in the forward-folding buffer spring mechanism 60, the insertion member 65 is inserted into the gap S between the other end 63f of the coil spring 63 and the spring receiving portion 34b of the tail gate 30 (lateral beam 34), The gap S is filled.

  The said insertion member 65 is formed in a substantially fan-shaped plate shape, as shown to FIGS. 9-11, and the tailgate part 30 (horizontal beam part) in the state which the principal part of a fan can rotate by the connection bolt 65p. 34) is connected to the spring receiving portion 34b. Then, as the insertion member 65 rotates around the connection bolt 65p, the substantially arc-shaped end edge portion of the insertion member 65 receives the other end portion 63f of the coil spring 63 and the spring support of the tail gate portion 30 (lateral beam portion 34). It will be inserted in the gap S between the parts 34b. At the substantially arc-shaped end edge portion of the insertion member 65, a first insertion portion 65a equal to the plate thickness, a low-projection second insertion portion 65b, and a relatively high-projection third insertion portion 65c Are formed side by side in the circumferential direction.

  Therefore, according to the dimension of the gap S between the other end 63 f of the coil spring 63 and the spring receiving portion 34 b of the tail gate portion 30 (lateral beam portion 34), as shown in FIG. The first insertion portion 65a, the second insertion portion 65b, or the third insertion portion 65c can be inserted into the gap S. Then, after the insertion member 65 is inserted into the gap S, the insertion member 65 is fixed to the spring receiving portion 34b of the tail gate portion 30 (lateral beam portion 34) by a rivet 65w or the like. Further, when the dimension of the gap S is smaller than the plate thickness dimension of the insertion member 65, the connection bolt 65p is removed and the insertion member 65 is removed from the spring receiving portion 34b of the tail gate portion 30 (lateral beam portion 34). Can.

<Handling of slope device 10>
In the state where the slope device 10 is stored in the vehicle C, as shown in FIG. 6, FIG. 7, etc., the slope plate main body portion 20 and the tailgate portion 30 are both in the standing position and The lock mechanism 50 is held in the locked state. When the passenger is put on the wheelchair in this state, the lock state of the backrest regulation lock device 40 is released, and the slope plate main body portion 20 and the tailgate portion 30 are integrated as shown in FIG. It is pivoted back to the deployed position around the pivoting center of the tilting hinge mechanism 31. Then, as shown in FIG. 2, the first flat plate portion 21 is pulled out from the second accommodation plate portion 22 of the slope plate main body portion 20, and the slope plate main body portion 20 is between the rear opening H of the vehicle C and the ground. It is possible to get on the passenger of the wheelchair from the rear opening H by using the slope plate body 20 by bridging.

  Further, as shown in FIG. 6, when loading a load onto the vehicle C from the state where the slope plate body portion 20 and the tailgate portion 30 are in the upright position, the left and right lever members 52 are operated to turn left and right. The lock state of the regulating lock mechanism 50 is released. As a result, the slope plate main body portion 20 can be pivoted downward to the front with respect to the tailgate portion 30 in the standing position. At this time, since the slope plate main body portion 20 is pivoted forward and downward against the spring force of the coil spring 63 of the forward-folding buffer spring mechanism 60, the slope plate main body portion 20 is gently advanced forward.

  Further, since the gap S between the other end 63f of the coil spring 63 and the spring receiving portion 34b of the tail gate 30 (the horizontal beam 34) is filled with the insertion member 65, the slope plate body 20 rotates downward forward. Spring force will be generated at the same timing. For this reason, the rotational speed at the time of tilting the slope plate main body 20 forward can always be made constant. The load can be loaded on the slope plate main body 20 in a state where the slope plate main body 20 is laid down on the floor surface. Further, when the slope plate main body portion 20 is pivoted upward in the upright position direction, the spring force of the coil spring 63 can be used, so that the slope plate main body portion 20 can be pivoted upward by a relatively small force.

Regarding Advantages of Slope Device 10 According to the Present Embodiment
According to the slope device 10 of the present embodiment, the insertion member 65 is the end portion of the coil spring 63 in a state where the slope plate main body 20 (vertical rotation member) is at the standing position and the coil spring 63 does not generate a spring force. 63f and the spring receiving portion 34b are inserted into the gap S. That is, the gap S between the end 63 f of the coil spring 63 and the spring receiving portion 34 b is filled with the insertion member 65. For this reason, when the slope plate body portion 20 pivots downward from the upright position to the fall position direction, the spring force of the coil spring 63 is generated at the same timing, and the slope plate body portion 20 pivots downward to the fall position at the same speed. become. As described above, by using the insertion member 65, the gap S does not occur between the end 63f of the coil spring 63 and the spring receiving portion 34b, so the coil spring 63 which becomes unusable due to the size of the gap disappears. Yield is improved.

  In addition, since the first insertion portion 65a, the second insertion portion 65b, and the third insertion portion 65c, which are a plurality of protrusions having different height dimensions, are formed in the insertion member 65, the number of insertion members 65 is large. The coil spring 63 can be accommodated. Furthermore, the insertion member 65 is attached to the spring receiving portion 34b in a rotatable state, and a plurality of protrusions (a first insertion portion 65a and a second insertion portion 65b) are formed on the arc-shaped end of the insertion member 65. , And the third insertion portions 65c) are formed side by side in the circumferential direction. For this reason, the insertion member 65 provided with a plurality of projections can be compactly formed. Furthermore, any of the first insertion portion 65a, the second insertion portion 65b, and the third insertion portion 65c can be inserted into the gap S in a state where the insertion member 65 is connected to the spring receiving portion 34b. Further, since the insertion member 65 is attached to the spring receiving portion 34b in a removable state, when the dimension of the gap between the end portion 63f of the coil spring 63 and the spring receiving portion 34b is small, the insertion member 65 may be removed. it can. Furthermore, since the insertion member 65 can be fixed to the spring receiving portion 34b in a state where the insertion member 65 is inserted into the gap S, the insertion member 65 does not come out of the gap S.

<Modification example>
Here, the present invention is not limited to the above embodiment, and changes can be made without departing from the scope of the present invention. For example, in the present embodiment, an example in which the coil spring 63 is used as a spring material of the forward-folding buffer spring mechanism 60 has been shown, but it is also possible to use, for example, a leaf spring instead of the coil spring 63. Further, in the present embodiment, the first insertion portion 65a, the second insertion portion 65b, and the third insertion portion 65c in the form of protrusions are formed along the circumferential direction at the arc-shaped end of the insertion member 65, and the insertion member 65 is formed. Has been shown to be coupled to the spring receiving portion 34b in a rotatable state. However, it is also possible to form the insertion member 65 in a band plate shape, and to form the first insertion portion 65a, the second insertion portion 65b, the third insertion portion 65c, etc. in a state of being aligned in the longitudinal direction of the insertion member 65 is there. Moreover, it is also possible to form the insertion member 65 in a bowl shape.
