The step filling device 18 is provided on the lowermost plate 5 whose front edge in the downward direction (front) shown by the arrow A protrudes, and on the second to fifth plates 4, 3, 2, the front edge of which is sequentially receded by L _1. , 1
Are overlapped and integrated by means such as bonding, bolting, or the like. In this embodiment, the bottom surface of the lowermost plate member 5 is bonded to the floor surface 15. Each of the plate materials 1 to 5 has a thickness of, for example, 7 m.
It is made of m plywood or wooden board, and five of them are filled with 35 mm steps.
α is the angle of the slope, L ₂ is the length of the step filling member 18 (the width of the slope), these values, for example, the extent to climb wheelchair wheels ride and manually, for example, 30 degrees or less and 7
It is set to 00 mm or more.

The corner step filling device 19 has a substantially fan shape when viewed from above, is similarly formed of the plate members 1a to 5a, and is adhered to the floor surface 15. This adds a function that enables the rider to climb from the direction of arrow B or descend in the opposite direction.

As means for integrating the plate members 1 to 5 constituting the step filling device 18, in addition to the above-mentioned bonding, for example, two through bolts 22 at the rear end can be adopted. FIG.
In the example, a bottomed counterbore 23 is provided on the upper surface of the uppermost plate 1 and the lower surface of the lowermost plate 5, and a bolt 22 is passed through the hole 24 coaxial with the counterbore 23 from above and the lower end thereof. A thin nut 25 is screwed. Reference numeral 26 denotes a washer, which is provided at the upper end of the bolt 22 with, for example, a plus groove in which a plus driver is engaged. The bolt 22 corresponds in advance to the total thickness of the five plate materials 1 to 5 (a length that does not project downward).
However, when changing the number of plate materials to be used to correspond to different steps, in order to save the labor of preparing bolts of dimensions corresponding to each number, a slightly longer 1 It is effective to employ a method of appropriately cutting the downward protruding portion by using various kinds of bolts. Hole 2
4 is provided in advance in all the plate materials 1 to 5, and the plate materials 2 and 3 which may be adopted in the uppermost stage have counterbore holes 23 on the upper surface.
It is also effective to provide counterbore holes 23 on the lower surface of the plate material 4 which may be employed at the lowermost stage in advance. In place of the bolt 22, a bolt having a predetermined length with a small-diameter male thread at the lower end is prepared, and a short refill having a female thread at the upper end with which the small-diameter male thread is screwed and having a small-diameter male thread at the lower end. A large number of bolts may be prepared, and the total length of the bolts may be adjusted according to the increase in the number of used plate members. In addition to the bolts 22 in FIG. 1, for example, bolts 22a for further fixing the lower two plates 4 and 5 can be similarly provided, and when the total number of plates is further increased, the bolts 22a are tightened. This is effective for increasing the number of plate materials. A non-slip tape 27 is stuck to the front end of the upper surface of each plate member of FIG. The provision of a coating is beneficial for safety. In addition, the front end of the upper surface of the plate material can be formed at a right angle, in which case an anti-slip effect can be expected.

As another means for integrating the respective plate members 1 to 5 in FIG. 1, opposing pin holes are provided at a plurality of locations on the joint surfaces of the respective plate members and are connected by, for example, wooden pins, or the respective plate members are double-sided tape. Can be joined. As another means for fixing the integrated step filling device 18 to the floor surface 15, similar pins and double-sided tape can be used.
Can be fixed to the vertical front surface of the sill 16 without or with the floor fixed to the floor 15,
If the step filling device 18 has an appropriate weight, or has a non-slip surface, a rubber film, a sheet or the like having a non-slip effect on the bottom surface, the wheelchair can be raised and lowered simply by simply placing it on the floor surface 15. May be possible. When the floor surface 15 is formed of a fluffy carpet, downward pins (posts ... not shown) provided at a plurality of locations on the bottom surface to prevent sinking when the wheelchair gets on or stepped on by a person. ) Can be supported on a carpet or a floor made of wood or the like beneath the carpet. The same applies to the method of integrating the corner stepping implement 19 and the method of fixing it to the floor surface 15 and the stepping implement 18.

Behind a protrusion, such as threshold 16 in FIG.
(The left side of the floor) is the same level as the floor surface 15 (when there is no tatami surface 17),
The same step-filling device (not shown) as in FIG. 8 can be arranged upside down to form a downward slope.

FIG. 3 shows, as a countermeasure for the case where the step is increased, for example, behind a block made of plate members 2, 3, and 4, three rectangular cross-section plates 11 and a block made of plate member 1 thereon are disposed as auxiliary tools. doing. When a plurality of plate members are additionally arranged below the plate member 4 to form a slope on the front surface, the same number of cross-section rectangular plates 11 as the additional plate members can be added, and when the width L _{3 of the} rectangular cross-section plate 11 is large, The plate members 2, 1 and the like may be sequentially stacked on the upper surface from below.

FIG. 4 is an end view of a plate material that can be employed.
1 to 5 correspond to the plate materials 1 to 5 in FIG. 1, but instead of providing a chamfered portion at the front edge, a step-down portion 30 inclined forward and downward is used.
(Corner drop portions) are formed. The plate materials 1 to 11 may be made of resin or rubber, or may be made of metal. For example, it is possible to use a thin iron plate formed by sheet metal molding into a generally U-shape having a U-shaped portion facing the front and rear, or an aluminum shape, in which case a plug made of wood or the like is fitted into the opening at both ends. The risk of tripping can be prevented, and the weather resistance and durability are improved. The thickness of these plate members can be, for example, 3 to 21 mm, and preferably about 7 mm. It is not necessary that all plate materials have the same thickness, but it is preferable.

FIGS. 6 (a) and 6 (b) show plate members 3, 4, 5, 6, 7 so that a wide area can be secured in the place where the vehicle has been completely climbed.
And step filling devices 18a and 19a employing the plate members 3a, 4a, 5a, 6a and 7a. Of course, it is free to add one or a plurality of plate members below these in relation to the step.

FIG. 7 is an end view showing an embodiment of the second invention, in which a front-rear width L ₆ (for example, 37 mm) of a front edge in the down direction A is shown.
The narrow band-shaped plate member 32 (having a thickness of, for example, 14 mm) has a narrow flat surface 33 at the rear portion of the upper surface, a slope 34 that decreases in front of the flat surface 33, and a slope 3 that further decreases in front of the flat surface 33.
4 has a steep slope 35 and a front end R portion 36,
Are integrated to form a block 38 by its bottom on a thin longitudinal width L _7, for example of 55 mm (e.g., 5mm) plate material 37 is wood screw 38.

The block 40 behind the block 38 is constructed by sequentially overlapping a rectangular cross-section plate 41 and a plate member 42 under the band-shaped plate member 32 and integrating them with wood screws 43. The blocks 38 and 40 are integrated by press-fitting the pins 46 into the pin holes 44 and 45 provided on the front surface of the block 40.

The block 48 behind the block 40 is formed by sequentially stacking two rectangular cross-section plates 41 and one plate member 42 below the band-shaped plate member 32 and integrating them with wood screws 39 and 43 and pins 49. The two blocks 40 and 48 are integrated by press-fitting a pin 46 into pin holes 44 and 45 provided on the back surface of the block 40 and the front surface of the block 48.

[0017] In FIG. 7, the shape before and after the width of the strip-like plate material 32 may also L ₆ or and the entire upper surface smaller than that things flat, or may be those with a gently inclined descending towards the leading edge. The plate members 37 and 42 at the bottom of each block can be omitted, and bonding, double-sided tape or other means can be used for connecting the constituent members of each block and connecting the blocks together. Further, between the blocks 38 and 40, at least one block (not shown) obtained by removing the upper band-shaped plate 32 from the block 40 is interposed, and the block 48 at the upper end from the block 48 is provided behind the block 48.
It is also possible to sequentially arrange at least one block (not shown) from which the number of intervening blocks has been reduced. When one intervening block is provided, the slope of the slope is reduced to half, and as the number of intervening blocks increases. The slope of the slope decreases.

[0018]

According to the first aspect of the present invention, the height adjustment can be optimally performed according to the step by making a slope that eliminates the step by stacking a plurality of thin plate materials in layers, and the slope angle can be adjusted. Can be freely selected by selecting a plate material with a wide front and rear width. Also, since the parts have a simple shape, anyone can easily assemble them. By changing the thickness of the plate material, it is possible to cope with any steps. The addition of the rectangular cross-section plate 11 (a rectangular parallelepiped member) has an advantage that the extension of the plane portion and the height adjustment can be easily performed. Furthermore, it is possible to cope with various heights by combining plate materials having different thicknesses. In this way, a slope (slope) can be installed at an optimum height at a step, that is, depending on age, conditions (diameter of wheelchair wheels, etc.), and conditions (bare feet, socks, shoes, etc.). Can be set. The step is linear (Fig. 1
Since a fan-shaped portion (corner step filling tool 19 in FIG. 1) can be selected instead of the step filling tool 18), there is an advantage that the vehicle can enter diagonally without entering straight. Although it is of an assembling type, any number of people can easily assemble it with bolts and nuts, screws, nails, tabs, a combination of irregularities, double-sided tape or an adhesive. As the surface non-slip processing, painting or spraying may be applied to the entire surface, a sheet or rubber may be applied, or cut lines or projections may be formed on the surface to prevent slippage.
When a horizontal surface is formed on the upper surface, the surface itself becomes non-slip. Slip on the bottom and back is rubber sheet or double-sided tape,
It is also possible to attach a cloth fastener, lay it underneath, take out a protrusion (a dowel, a pin, etc.), make a cut, and the like. For installation, it may be fixed with screws, nails, bolts and nuts.

According to the second aspect of the present invention, each block can be formed by using only a simple-shaped member such as the band-shaped plate member 32 having a narrow front-rear width and the rectangular plate 41, so that the cost can be reduced and all steps can be handled. There are advantages that can be done.
