"Slope body 2"
The slope main body 2 is constructed by arranging two long rectangular plate members 2A and 2B in parallel in the lateral direction, and connecting long sides facing each other by a flexible hinge 10 so as to be bendable and spreadable. Be done. Further, a reinforcing side edge member 9 which also functions as a wheel stopper is attached to the outer edge portion of each of the plate members 2A and 2B.

  Further, as shown in FIG. 7, each of the plate members 2A and 2B is configured by sticking reinforcing sheets 26 on both the front and back sides of a core 25 made of a resin plate having a predetermined thickness, and metal at both ends. An end member 8 made of steel is mounted horizontally.

  The end member 8 functions as a connecting member for connecting the high side end slope 3 and the low side end slope 4 described below, and as shown in the enlarged view of FIG. A fitting recess 21 and a protrusion 23 are formed on the lower end side of the frame, and an abutting portion 22 is formed on the upper end side of the outer end edge over the entire length of the end member 8 in the longitudinal direction.

  Further, as shown in FIGS. 1 to 3, a support 7 is provided at a position corresponding to the end member 8 on the lower surface of the slope main body 2. The support 7 supports the high end portion 2 a and the low end portion 2 b of the slope body 2 on the low installation surface Gb.

  In this embodiment, as shown in FIG. 1 and FIG. 2, on the high potential side end 2a side of the slope main body 2, the high potential side end 2a is located in the immediate vicinity of the high potential side installation surface Ga and is high. It is supported so as to be substantially parallel to the side installation surface Ga. On the other hand, on the lower end 2b side of the slope main body 2, the high end is positioned such that the end closer to the high position Gb1 of the high installation surface Ga is positioned at a predetermined height from the lower installation surface Gb. It supports the end close to Gb1 and the end close to lower part Gb2.

  Therefore, the required length of each support 7 provided in the slope main body 2 differs depending on the distance between the slope main body 2 and the lower installation surface Gb in the height direction, and this corresponds to this. In the embodiment, the support 7 has a connection structure of a plurality of pieces 7a, and adjustment can be performed with a length by increasing or decreasing the number of pieces 7a connected according to the arrangement position of the support 7. By adjusting the length of the support 7 as described above, the slope main body 2 has the posture in which the surface direction in the slope width direction of the upper surface (i.e., tread surface) matches the surface direction of the high-level installation surface Ga. It will be supported and fixed on the installation surface Gb.

  However, in this state, the height between the high end 2a of the slope body 2 and the high installation surface Ga, and between the low end 2b of the slope body 2 and the low installation surface Gb A relatively large step is produced in the direction, and the step is the largest at the lower portion Gb2 side of the lower end 2b in particular, from the high end 2a of the slope body 2 to the higher installation surface Ga. It is difficult to get on / off and to get on / off from the lower end 2b of the slope body 2 to the lower installation surface Gb. Therefore, in order to eliminate the difference in level at the both ends of the slope main body 2, the high end 2 a and the low end 2 b of the slope main body 2 respectively have a high end slope 3 and a low end slope 4 described below. Are linked.

"High side end slope 3"
As shown in FIGS. 1 and 2, the high end slop 3 includes a pair of left and right integrated slopes X connected to the high end 2 a of the slope main body 2. This integrated slope X has a connection structure similar to that of the lower end slope 4 described later shown in FIG. 7, and in FIG. 7 (with regard to the higher end slope 3, reference numerals in parentheses are attached thereto. And a wide rectangular plate 5 having a bowl-like cross-sectional shape. At the lower position of the base end of the rectangular plate 5, the fitting ridges 61 fitted to the fitting concaves 21 provided on the end member 8 on the side of the slope main body 2 and the ridges 23 correspond to A recessed groove 63 is provided, and an abutting portion 62 corresponding to the abutting portion 22 on the end member 8 side is provided at a position close to the upper portion of the base end.

  The rectangular plate 5 is configured to be rotatable in the vertical direction centering on the fitting portions by fitting and inserting the fitting ridges 61 into the fitting concaves 21. The upward movement of the rectangular plate 5 is restricted by the contact between the contact portion 22 on the slope main body 2 and the contact portion 62 on the rectangular plate 5. Further, the downward movement of the rectangular plate 5 is performed by the engagement of the ridge 23 on the slope main body 2 side and the concave groove 63 on the rectangular plate 5 side.

  The high-end end slope 3 consisting of the pair of integral slopes X is fitted with the fitting concave 21 because the high-end end 2a of the slope main body 2 is supported by the support column 7. It moves downward centering on the fitting part with the strip 61, and the tip end side is held in contact with the high side end 2a so that the posture is maintained, and the high side end 2a and the slope main body 2 are continuously joined. . Therefore, traveling of the wheelchair between the high end portion 2 a and the slope main body 2 is facilitated by the high end end slope 3, and the safety thereof is secured.

"Low end side slope 4"
The lower end slope 4 has a pair of left and right divided slopes Y connected to the lower end 2b of each slope main body 2 as shown in FIGS. 1 to 4 and 6 to 7 Configured The divided slope Y has a connection structure similar to that of the high-order end slope 3 as shown in FIG. 7, and has a plurality of (in this embodiment, a plurality of (five in this embodiment) single rectangular rectangles having a wedge-shaped cross section. The plates 6 are arranged in a row in the width direction along the lower end 2b of the slope body 2 and connected so as to be relatively rotatable around the row axis L.

  That is, at the lower end position of the base end of the single plate 6, the fitting ridges 61 fitted to the fitting concaves 21 provided on the end member 8 on the slope main body 2 side and the ridges 23 A corresponding recessed groove 63 is provided, and a contact portion 62 corresponding to the contact portion 22 on the end member 8 side is provided at a position closer to the upper portion of the base end. And this single plate 6 is comprised so that it can be vertically rotated centering | focusing on these fitting parts by fitting-inserting the said fitting protrusion 61 in the said fitting recess 21. As shown in FIG. The upward movement of the single plate 6 is restricted by the contact engagement between the contact portion 22 of the slope main body 2 and the contact portion 62 of the rectangular plate 5. Further, the downward movement of the single plate 6 is performed by the engagement of the protrusion 23 on the side of the slope main body 2 and the recessed groove 63 on the side of the rectangular plate 5.

  The lower end slope 4 composed of the pair of split slopes Y is fitted with the fitting concave 21 because the lower end 2b of the slope body 2 is supported by the support column 7. The posture is maintained by moving downward around the fitting portion with the bar 61 and bringing its tip end side into contact with the high end portion 2a.

  In this case, since the surface direction in the width direction of the slope main body 2 is different from the surface direction of the low end portion 2b, each single plate 6 of each divided type slope Y has a downward moving angle in order The slope surface increases while changing as it moves from the high-level portion Gb1 side to the low-level portion Gb2 side of the low-level installation surface Gb, and forms a slope surface that extends while twisting in the width direction of the slope main body 2 as a whole. As a result, the lower installation surface Gb and the slope main body 2 are continuously joined, and the step between the two is eliminated. Therefore, traveling of the wheelchair between the lower end 2 b and the slope body 2 is facilitated by the lower end slope 4, and the safety thereof is secured.

  As described above, each veneer 6 of the low end slope 4 is changed by changing the downward movement angle of the low installation surface Gb with respect to the surface direction of the slope main body 2. Although the step between the lower installation surface Gb and the slope main body 2 is eliminated and the both are continuously connected, the lower installation surface Gb has unevenness, for example. Even irregular surfaces or curved surfaces with undulations can be exhibited. That is, as shown in FIG. 5, even if the lower side installation surface Gb is a curved surface having an undulation, the respective veneers 6 move downward corresponding to the curved shape to lower the tip end portion to the lower side. By contacting the installation surface Gb, the difference in level between the lower installation surface Gb and the slope main body 2 is eliminated, and both are connected continuously. Therefore, traveling of the wheelchair between the lower end 2 b and the slope body 2 is facilitated by the lower end slope 4, and the safety thereof is secured.

  As described above, according to the slope device 1 of this embodiment, the low-order end slope 4 connected to the end of the slope main body 2 is configured by the split slope Y, whereby the high-level installation surface of the stepped portion The low end portion 2b of the slope body 2 and the low setting surface Gb of the stepped portion are continuously connected by the divided slope Y regardless of the surface shape of Ga and the low setting surface Gb or the relative relationship between them. Slopes are connected to each other and safe travel of the wheelchair is ensured by passing through the slopes. As a result, the slopes are excellent in safety, flexible in installation and versatile. The device 1 can be provided.

  In this embodiment, among the high-level installation surface Ga and the low-level installation surface Gb, the high-level installation surface Ga is a horizontal plane, and the low-level installation surface Gb is inclined with respect to the high-level installation surface Ga. On the contrary, in the case where the lower installation surface Gb is a horizontal plane and the high installation surface Ga is inclined with respect to the lower installation surface Gb. The slope device 1 may be used upside down so that the lower end slope 4 side corresponds to the higher installation surface Ga and the higher end slope 3 corresponds to the lower installation surface Gb.

  Further, in this embodiment, the high end portion 2a of the slope main body 2 is supported by the support column 7, but instead, the tip end portion of the high end end slope 3 is the high position installation surface If it installs in Ga directly, the support | pillar 7 which supports the high side end 2a part of the said slope main body 2 can be made unnecessary.

The slope device 1 is regarded as a modification of the slope device 1 according to the first embodiment. In the slope device 1 according to the first embodiment, the high-order end slope 3 is integrated. While the low side end slope 4 is constituted by the split type slope Y while being constituted by the slope X, both the high side end slope 3 and the low side end slope 4 are constituted by the divided type slope Y .

  According to the configuration, it goes without saying that when the lower installation surface Gb is inclined with respect to the horizontal plane as in the first embodiment, both the high installation surface Ga and the lower installation surface Gb are horizontal planes. It can also be applied to the case where it is inclined with respect to the surface, or both the high-level installation surface Ga and the low-level installation surface Gb are irregular surfaces with asperities or curved surfaces with undulation, and the installation freedom Can provide a highly versatile slope device 1.
