Description

本発明は、上下方向に段差がある上段部と下段部との間、あるいは車両の床部と地上面との間等に斜めに架け渡してスロープ面を形成し、車椅子等が走行できるようにするスロープ装置に関する。   The present invention allows a wheelchair or the like to run by forming a slope surface between the upper step and the lower step having a step in the vertical direction or between the vehicle floor and the ground surface to form a slope surface. Relates to a slope device.

車両の乗降用にスロープ面を形成することは公知であり、例えば特許文献１には複数の短冊状板を蝶番にて連結したスロープ装置を開示する。
このように複数の短冊状板を蝶番で連結したものは、蝶番で屈曲可能なので収納しやすい利点があるものの、車椅子等が走行する際の荷重がこの蝶番での連結部に集中し、スロープ面に撓みや小さな段差が生じやすい。 It is known to form a slope surface for getting on and off a vehicle. For example, Patent Document 1 discloses a slope device in which a plurality of strip-like plates are connected by a hinge.
In this way, connecting a plurality of strip-shaped plates with a hinge has the advantage of being easy to store because it can be bent with a hinge, but the load when a wheelchair etc. travels concentrates on the connecting part at this hinge, and the slope surface Tends to cause bending and small steps.

そこで本出願人はスロープ面を複数のフロア部材で形成するとともに、隣接するフロア部材間の係合部に相互に対向する対向面を形成し、対向面同士を重なり合せることで車椅子等の走行時に加わる荷重を複数のフロア部材で一体的に受ける構造を提案している（特許文献２）。
本発明は特許文献２に記載の発明をさらに発展させ、車椅子等の走行時に発生する集中荷重をスロープ面全体に、より確実に、分散させようとしたものである。 Therefore, the present applicant forms a slope surface with a plurality of floor members, forms opposing surfaces opposite to each other between the engaging portions between adjacent floor members, and overlaps the opposing surfaces when traveling a wheelchair or the like. The structure which receives the applied load integrally with a plurality of floor members is proposed (patent document 2).
The present invention is a further development of the invention described in Patent Document 2, and is intended to more surely distribute the concentrated load generated during traveling of a wheelchair or the like over the entire slope surface.

特開平１１−１３９２１０号公報JP-A-11-139210 特許第３９０９７３９号公報Japanese Patent No. 39099739

本発明は斜めに架け渡して形成するスロープ面を複数のフロア部材にて構築する場合にスロープ面に加わる荷重の分散性に優れ、軽量化を図るのに効果的なスロープ装置の提供を目的とする。   An object of the present invention is to provide a slope device that is excellent in dispersibility of a load applied to a slope surface when a slope surface that is formed obliquely across a plurality of floor members is constructed, and is effective for reducing weight. To do.

本発明に係るスロープ装置は、上下方向に段差がある上段部から下段部にかけて傾斜したスロープ面を形成するためのスロープ装置であって、前記スロープ装置はスロープ面の傾斜方向に沿ってスロープの左右の端縁部を形成する左及び右サイドレールと、当該左右のサイドレール間を連結し、面一のスロープ面を形成するフロアパネルとを有し、前記フロアパネルは左右のサイドレールと直交する方向に複数分割したフロア部材で構成されるとともに、相互に隣接するフロア部材間にスロープ面に直交する方向に透視した際に相互に重なり合い、スロープ面に沿ってｄ＞０からなる重なり代（ｄ）を有するように重なり部を有し、前記重なり部はフロア部材の左右方向概ね全長にわたって形成されているとともに重なり代全長にわたって、接着剤を除いた弾性材を挟持させたことを特徴とする。 A slope device according to the present invention is a slope device for forming a slope surface that is inclined from an upper step portion having a step in the vertical direction to a lower step portion, wherein the slope device is provided along the slope direction of the slope surface. Left and right side rails forming end edges of the left and right side rails, and a floor panel connecting the left and right side rails to form a flush slope surface, the floor panel being orthogonal to the left and right side rails together are constituted by a floor member which is divided into a plurality directions, mutually have if overlapping each other when seen through in a direction perpendicular to the slope surface between floor members adjacent consists d> 0 along the slope surface overlapping margin have overlapping portions so as to have a (d), over the cash entire length overlap with the overlapping portion is formed over a lateral direction substantially the entire length of the floor members, Characterized in that by sandwiching the elastic member except for Chakuzai.

本明細書おいては、斜めに形成されたスロープ面に向かって、左右と表現する。
また、スロープ面と上下に直交する方向に相互に重なり合うとは、相互に隣接するフロア部材において、相方のフロア部材の隣接側のそれぞれの側縁端部をスロープ面と直交する方向に透視した透視図を描くと、相互の側縁端部に重なり部分が生じることをいい、特に本発明にあってはこの重なり部分の間に弾性材を介在させた点にある。
ここで、前記重なり部分の間に弾性材を介在させるとは、スロープ面に直交する方向に透視した際に、相互に重なる部分に少なくとも弾性材を有すればよく、必ずしも隣接するフロア部材間の端面の対向面全体にわたって弾性材を介在させる必要はない。
なお、弾性材の一部がスロープ面に露出又は突出するように介在させると弾性材による滑り止め効果も作用する。
また、弾性材は軟質の樹脂でもよいが、ゴム弾性を有するものが好ましく、シート状、ランチャンネル状等形状に制限はない。 In this specification, it expresses as right and left toward the slope surface formed diagonally.
In addition, overlapping with each other in the direction perpendicular to the slope surface in the vertical direction means that, in the floor members adjacent to each other, the respective side edge ends on the adjacent side of the opposite floor member are seen through in the direction perpendicular to the slope surface. When drawing a figure, it says that an overlapping part arises in a mutual edge part, and in this invention, it exists in the point which interposed the elastic material between this overlapping part especially.
Here, interposing an elastic material between the overlapping portions means that at least the elastic material is provided in the overlapping portions when seen through in a direction orthogonal to the slope surface, and is not necessarily between adjacent floor members. It is not necessary to interpose an elastic material over the entire opposing surface of the end surface.
In addition, if it interposes so that a part of elastic material may be exposed or protrudes on a slope surface, the anti-slip effect by an elastic material will also act.
Further, the elastic material may be a soft resin is preferably a material having a rubber elasticity, the sheet-like, the run channel shaped like shape restrictions have greens.

本発明において、前記サイドレールは複数のフロア部材のスロープ面が面一になるように当該フロア部材の端部を表面と裏面とから挟持固定してあると弾性材による荷重分散効果がさらに向上する。
また、前記フロア部材はスロープ面を形成する本体部と前記重なり部とがアルミニウム合金の押出材で製作してあり、前記本体部は中空断面形状にするとフロア部材の剛性を維持しつつ軽量化を図るのに有効である。 In the present invention, the load distribution effect by the elastic material is further improved when the end portion of the floor member is sandwiched and fixed from the front surface and the back surface so that the slope surfaces of the plurality of floor members are flush with each other. .
Further, the floor member is made of an extruded material of an aluminum alloy in which the main body part forming the slope surface and the overlapping part are made, and when the main body part is formed in a hollow cross-sectional shape, the floor member is kept light in weight while maintaining the rigidity. It is effective to plan.

また、本発明に係るスロープ装置は車両用スロープ装置として採用することもでき、その場合に前記請求項１〜４のいずれかに記載のスロープ装置であって、車両の床部から地上面にかけて傾斜したスロープ面を形成するものであり、前記左右のサイドレールとフロアパネルとからなるスロープ部材を複数有し、当該複数のスロープ部材が折りたたみ収納及び展開又はスライド収納及び展開するものであってもよい。
車両の床部と地上面との間にスロープ面を形成する場合に地上面は必ずしも平坦ではなく、スロープ装置全体を完全に固定するのが難しく、スロープ面に撓みや複数のフロア部材間に段差が生じると車椅子等の走行性に不安が生まれるが、本発明に係るスロープ装置にあっては、スロープ面に加わる荷重をスロープ面全体に分散させるので、そのような不安が解消する。 Further, the slope device according to the present invention can also be adopted as a vehicle slope device, in which case the slope device according to any one of claims 1 to 4, wherein the slope device is inclined from the floor of the vehicle to the ground surface. A plurality of slope members composed of the left and right side rails and a floor panel, and the plurality of slope members may be folded and stowed or unfolded or slides stowed and unfolded. .
When the slope surface is formed between the floor of the vehicle and the ground surface, the ground surface is not always flat, it is difficult to completely fix the entire slope device, and the slope surface is bent or a step between multiple floor members. However, in the slope device according to the present invention, since the load applied to the slope surface is distributed over the entire slope surface, such anxiety is resolved.

本発明に係るスロープ装置にあっては、複数のフロア部材に相互に重なり合う重なり部を形成し、この重なり部間に弾性材を介在させながら、傾斜したスロープ面を形成したので、この斜面を車椅子等が走行する際の荷重によるフロア部材の局部変形をこの弾性材が吸収し、隣接するフロア部材が重なり部において平面的に重なるように作用するので、荷重の分散性に優れる。
これにより、フロアパネル全体の剛性を維持しつつ軽量化を図ることができる。
また、一般的にゴム等の弾性材は比重が約０．９前後であり、アルミニウム合金の比重約２．７よりも軽く、アルミニウム合金からなる重なり部にてこの弾性材を介在させて、面当たりさせながら、スロープ面が面一になるようにすると、弾性材の厚みに相当する分のアルミニウム合金との比重差だけ軽量化されることになる。 In the slope device according to the present invention, an overlapping portion is formed on a plurality of floor members, and an inclined slope surface is formed while an elastic material is interposed between the overlapping portions. This elastic material absorbs the local deformation of the floor member due to the load when the vehicle travels, and the adjacent floor members act so as to overlap in a plane in the overlapping portion, so that the load dispersibility is excellent.
Thereby, weight reduction can be achieved, maintaining the rigidity of the whole floor panel.
In general, an elastic material such as rubber has a specific gravity of about 0.9, which is lighter than an aluminum alloy specific gravity of about 2.7. If the slope surface is flush with the contact, the weight is reduced by the specific gravity difference from the aluminum alloy corresponding to the thickness of the elastic material.
