[1-5. Mounting structure]
Next, the mounting structure of the inversion slope 1 will be described.
The reversing slope 1 is disposed and fixed above the pedestal 30 with the slope plate 20 deployed relative to the base member 10. Positioning of the base member 10 with respect to the pedestal portion 30 in the left-right direction can be performed by bringing the protrusions 17a into contact with the pedestal portion 30 from the inside of the vehicle. And if the base member 10 is arrange | positioned in the suitable position above the base part 30, the base member 10 is fixed with respect to the base part 30 by screwing the fastening bolt 52 to the nut 51 welded to the horizontal stiffener 33. Fix it. Thus, in a state where the base member 10 is fixed to the pedestal portion 30, the elastic body 70 contacts the lower surface of the base member 10 and the upper surface of the pedestal portion 30.

The fastening bolt 52 is inserted from above the base member 10 into the base-side bolt hole 19 of the base member 10 disposed above the pedestal portion 30 and the pedestal-side bolt hole 35 provided at a location corresponding thereto. The The fastening bolt 52 is fastened with a nut 51 provided corresponding to the pedestal side bolt hole 35.
As shown in FIG. 1, a cap 40 made of a thermoplastic resin is attached above the fastening bolt 52 and the nut 51 fastened as described above so as to cover the exposed upper surface of the fastening bolt 52. The cap 40 is inserted into the upper bolt holes 19b from above and locked to the base member 10. Thereby, each upper bolt hole 19b opened in the main body upper portion 15 is closed.

The cap 40 is formed with a flange 41 having a diameter larger than the diameter of the upper bolt hole 19b, and the cap 40 is secured to the edge of the upper bolt hole 19b. It is attached to the upper surface of the base member 10.
The cap 40 is provided with an upper surface portion 42 projecting upward from the upper surface of the base member 10. The amount of protrusion of the upper surface portion 42 of the cap 40 is the height dimension of the gap S formed between the base member 10 and the slope plate 20 in the retracted state (that is, the upper surface of the base body 13 and the surface of the slope portion 22). The distance is set so as to be approximately the same.

For this reason, the upper surface part 42 of the cap 40 contacts the slope part 22 of the slope plate 20 in the retracted state. As a result, the slope plate 20 in the retracted state is supported at both ends by the hinge portion 25 and the tip slope portion 26, and is also supported by the base member 10 through the cap 40. That is, in the present embodiment, the slope plate 20 in the retracted state is supported by the base member 10 via the seven caps 40.
The cap 40 attached to the base-side bolt hole 19 corresponding to the pedestal-side bolt hole 35 provided in the longitudinal central portion of the lateral stiffener 33B is connected to the hinge portion 25 and the tip slope portion 26 of the slope plate 20 in the retracted state. It contacts the center position of the middle part. As a result, the center position of the slope plate 20 is supported by the base member 10 via the cap 40.

[2. effect]
(1) According to the mounting structure of the reversing slope 1 described above, since the upper surface portion 42 of the cap 40 abuts against the slope plate 20 in the retracted state, even if an occupant gets on the slope plate 20 in the retracted state, the base In the gap S between the member 10 and the slope plate 20, the cap 40 functions as a tension member, and receives a passenger load from the slope plate 20. Thus, the slope plate 20 is supported by the base member 10 and the pedestal portion 30 not only through the one end portion (hinge portion) 25 and the other end portion (tip inclined surface portion) 26 but also through the cap 40.

Therefore, even if a load acts on the slope plate 20 in the stored state from above, the load is transmitted to the base member 10 and the pedestal 30 via the cap 40 in addition to the one end 25 and the other end 26. The slope plate 20 can be reliably supported and the deformation of the slope plate 20 can be prevented. Therefore, it is not necessary to increase the rigidity so that the slope plate 20 is not deformed, or to increase the size of the pedestal portion 30 in order to hold the slope plate, and the cost can be reduced.
Moreover, since the base member 10 and the base part 30 are fastened by the fastening bolt 52 and the nut 51, the reversible slope 1 can be easily attached to and detached from the base part 30, and the attachment / detachment time can be shortened. it can.

(2) Since the slope plate 20 has the hollow part 21, the slope plate 20 can be reduced in weight, and the weight reduction of the reversing slope 1 can be achieved by this. Further, since the slope plate 20 is an aluminum extrusion-molded body, the manufacture is easy.

  In the above-described embodiment, a bus (non-step bus) is exemplified as a vehicle. However, the present structure is not limited to this, and can be applied to a reversing slope attached to various vehicles such as a one-step bus, a train, and a passenger car. . In the above description, the reversing slope 1 attached to the boarding opening 6 provided on the side surface of the vehicle body has been described. However, the reversing slope to which the present structure is applied is, for example, a boarding opening (rear door) provided on the rear surface of the vehicle body. May be attached).

  In the above description, the fastening bolt 52 is fastened from above to the nut 51 welded to the lateral stiffener 33. For example, the fastening bolt 52 is welded to the lateral stiffener 33, and The nut 51 may be fastened from above. In this case, the cap 40 attached to the first bolt hole 19 is provided so as to cover the exposed upper surface of the nut 51.

  The cap 40 only needs to have a shape in which the upper surface portion 42 projects upward from the upper surface of the base member 10 and contacts the slope plate 20 in the retracted state with the cap 40 attached to at least the first bolt hole 19. The specific shape is arbitrary. However, if the cap 40 includes the flange portion 41 as described above, the cap 40 can be easily and reliably locked to the first bolt hole 19. Moreover, the load from the slope board 20 can be efficiently transmitted to the base member 10 via the collar part 41, and the slope board 20 can be supported more stably.

  The base body 13, the vertical frame member 11, and the slope plate 20 may be all or selectively formed solid with the hollow portions 18, 11 c, 21 omitted. For example, when the base body 13 is formed solid with the hollow portion 18 omitted, the upper hole diameter of the first bolt hole 19 is formed larger than the lower hole diameter, and the fastening bolt 52 is locked by these stepped portions. If comprised so, the fastening bolt 52 can be inserted into the 1st bolt hole 19 from upper direction, and can be fastened with the nut 51 similarly to the above-mentioned embodiment.

Further, the materials such as the base member 10, the slope plate 20, and the cap 40 described above are examples, and the base member 10 and the slope plate 20 may be formed of a material other than aluminum such as a thermoplastic resin. The cap 40 may be made of a material other than a thermoplastic resin such as a hard rubber material.
Furthermore, the pedestal portion 30 may not be attached to the portion cut out from the floor surface portion 2 as described above, and may be recessed in the floor surface portion 2, for example.

Either or either of the stiffeners 33 and 34 may be omitted, and the number and arrangement thereof are arbitrary. Normally, the wheelchair wheel that passes over the reversing slope 1 is located on the upper surface of the base member 10 between the region corresponding to the space between the lateral stiffeners 33A and 33B shown in FIG. Pass through the area corresponding to. For this reason, if the three horizontal stiffeners 33 are provided at the front end portion, the rear end portion, and the intermediate portion of the bottom surface portion 31a as described above, the cap 40 is disposed in the region through which the wheelchair wheel passes. This can avoid the risk of failure.
On the other hand, if the horizontal stiffener 33 is disposed in the two regions through which the wheelchair passes, the load that the base member 10 receives when the wheelchair passes can be effectively supported by the horizontal stiffener 33.

The specific shape of the protrusion 17a is arbitrary. For example, when the base member 10 is not an extrusion molded body, the protrusion 17a is formed at both ends in the longitudinal direction of the hinge portion 17 (here, the vehicle longitudinal direction). May be.
