Description

本発明は、スロープを反転操作するために取り付けられている取手の取付構造に関する。 TECHNICAL FIELD The present invention relates to a mounting structure for a handle mounted for reversing a slope.

自動車やバス等に車椅子等が乗降できるように車両のフロアから車外側に反転し、スロープ面を形成できるスロープ装置が特許文献１等に提案されている。
スロープには、特許文献１には記載がないが、使用時に車外に向けて展開操作し、使用しない時には車室内側に反転収納しやすいように取手が取り付けられている。
しかし、従来の取手の取付構造は、取手にシャフト状の取付軸部を形成し、この取付軸部を回動可能に連結した取付孔を有しているが、この取付孔の断面形状が円孔になっていた。
そのために、スロープを車室内側に反転収納する際に取手の取付軸部が円孔に沿って回動することなく、そのままスロープ荷重を受けたまま、スロープ面が取手により浮き上がった状態になる場合があった。 Japanese Laid-Open Patent Application Publication No. 2002-100000 proposes a slope device that can be turned from the floor of a vehicle to the outside of the vehicle to form a slope surface so that a wheelchair or the like can get in and out of an automobile or bus.
Although not described in Patent Document 1, a handle is attached to the slope so that it can be deployed toward the outside of the vehicle when in use, and can be easily reversed and stored inside the vehicle when not in use.
However, in the conventional handle mounting structure, a shaft-shaped mounting shaft portion is formed in the handle and has a mounting hole to which the mounting shaft portion is rotatably connected. It had become a hole.
For this reason, when the slope is reversed and stored inside the passenger compartment, the mounting shaft of the handle does not rotate along the circular hole, and the slope surface is lifted by the handle while receiving the slope load. was there.

本発明は、スロープを収納する際に取手がスムーズに格納されるスロープの取手構造の提供を目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a handle structure for a slope that allows the handle to be smoothly stored when the slope is stored.

本発明に係るスロープの取手取付構造は、スロープを展開操作するための取手の取付構造であって、前記スロープは展開操作する取手と、前記取手を回動可能に取り付けるための取付部とを有し、前記取付部は取付孔を有し、前記取手は前記取付孔に挿通連結した取付軸部を有し、前記取付孔は長孔形状になっていることを特徴とする。
ここで、前記長孔形状の長軸方向の長軸中心線とスロープ面との連結角（θ）は鋭角であるのが好ましい。 A handle mounting structure for a slope according to the present invention is a structure for mounting a handle for deploying a slope, wherein the slope has a handle for the deploying operation and a mounting portion for rotatably mounting the handle. The mounting portion has a mounting hole, the handle has a mounting shaft portion inserted into and connected to the mounting hole, and the mounting hole is elongated.
Here, it is preferable that the connection angle (.theta.) between the long axis center line in the long axis direction of the long hole shape and the slope surface is an acute angle.

本発明において、スロープは車椅子等の乗降時には車外側に展開し、路面と車両フロアとの間に架け渡され、スロープ面を形成でき、使用しない時には車両のフロア側に反転収納できるスロープであれば、その構造に制限がなく、複数のスロープ部材をスライド式に伸縮するものや複数のスロープ部材を折り畳み収納するものが例として挙げられる。
本発明において、取手は車室側に反転したスロープ面の下面側に取り付けられていて、スロープの自重により、取手がスロープ側に倒れるように折り畳まれる。 In the present invention, the slope can be deployed outside the vehicle when a wheelchair or the like is getting on and off, can be bridged between the road surface and the vehicle floor, can form a slope surface, and can be reversed and stored on the floor side of the vehicle when not in use. There are no restrictions on the structure, and examples include those in which a plurality of slope members are slidably extended and retracted, and those in which a plurality of slope members are folded and stored.
In the present invention, the handle is attached to the underside of the slope surface that is reversed toward the passenger compartment, and is folded by the weight of the slope so that the handle falls down on the slope side.

本発明に係る取手の取付構造にあっては、取手の取付軸部を回動支持した取付孔の断面形状を長孔形状にしたことにより、取手にスロープの倒れ込み方向の自重が加わる際に取付軸部が長孔の長軸方向に沿って移動するので、取手の先端側がスロープ側に倒れ込みやすくなる。 In the handle mounting structure according to the present invention, the cross-sectional shape of the mounting hole that pivotally supports the mounting shaft of the handle is elongated. Since the shaft portion moves along the longitudinal direction of the long hole, the tip side of the handle tends to fall toward the slope side.

（ａ）～（ｃ）は取手が倒れる流れを示す。(a) to (c) show the flow in which the handle falls down. スロープの先端側に設けた取手の構造例を示す。An example of the structure of a handle provided on the tip side of the slope is shown.

本発明に係るスロープの取手の取付構造例を以下、図に基づいて説明するが、本発明はこれに限定されない。 An example of the attachment structure of the handle of the slope according to the present invention will be described below with reference to the drawings, but the present invention is not limited to this.

図２に、スロープ１０の展開先端側を部分的に示す。
図２（ａ）は、スロープを車外側に展開し、路面と車両のフロアとの間にスロープ面を形成した状態を部分的に示す。
スロープ面にリング形状の取手１２が、スロープ１０側に設けた取付部１１に回動自在に連結されている。
このスロープ１０を車室内側に反転し、スロープ１０が車両のフロア１に格納（収納）される状態を図１に示す。 FIG. 2 partially shows the deployment tip side of the slope 10 .
FIG. 2(a) partially shows a state in which the slope is developed outside the vehicle to form a slope surface between the road surface and the floor of the vehicle.
A ring-shaped handle 12 is rotatably connected to a mounting portion 11 provided on the slope 10 side on the slope surface.
FIG. 1 shows a state in which the slope 10 is reversed to the inside of the vehicle compartment and the slope 10 is stored (stored) in the floor 1 of the vehicle.

リング状の取手１２は、一方がシャフト状の取付軸部１２ａになっていて、他方が手でのつかみ部となりカラー１２ｂが取り付けられている。
スロープ１０側に固定した取付部１１は、長孔の取付孔１１ａを有し、この取付孔１１ａに取手の取付軸部１２ａが挿通連結されている。
取付軸部１２ａは断面円形状になっていて、取付孔１１ａは短径と長径との長孔形状になっていて、長径側の長軸中心線１３とスロープ１０のスロープ面との間の連結角（取付角）θが９０°以下の鋭角になっている。 One side of the ring-shaped handle 12 is a shaft-shaped attachment shaft portion 12a, and the other side is a grip portion with a hand and a collar 12b is attached.
The mounting portion 11 fixed to the side of the slope 10 has an elongated mounting hole 11a, and the mounting shaft portion 12a of the handle is inserted and connected to the mounting hole 11a.
The mounting shaft portion 12a has a circular cross section, and the mounting hole 11a has an elongated hole shape with a short diameter and a long diameter, and a connection between the long axis center line 13 on the long diameter side and the slope surface of the slope 10 is provided. The angle (mounting angle) θ is an acute angle of 90° or less.

図１に基づいて取手１２の動きを説明する。
スロープ１０を車室内側に格納するのに、図１（ａ）に示すようにスロープ１０のスロープ面が車室内側に倒れ込む。
取手１２は真下に垂下した状態で、つかみ部側のカラー１２ｂがフロア１の上面に当たる。
その荷重が取付軸部１２ａに伝わるが、取付孔１１ａが鋭角の連結角θからなるので、取付軸部１２ａが長孔の長径方向に沿ってズレる。
これにより、取手１２のつかみ側が図１（ｂ），（ｃ）に示すように、そのまま倒れ込むので、スロープ１０がスムーズに車室内側に格納される。 The movement of the handle 12 will be described with reference to FIG.
In order to store the slope 10 inside the passenger compartment, the slope surface of the slope 10 collapses inside the passenger compartment as shown in FIG. 1(a).
The collar 12b on the side of the handle contacts the upper surface of the floor 1 while the handle 12 hangs down.
The load is transmitted to the mounting shaft portion 12a, but since the mounting hole 11a has an acute connecting angle θ, the mounting shaft portion 12a is displaced along the major axis direction of the elongated hole.
1(b) and 1(c), the slope 10 is smoothly retracted inside the passenger compartment.
