Description

本発明は、通路に形成される段差部の下段面に配置してこの段差部を解消し通行し易い傾斜路を形成するためのスロープ装置に関するものである。 The present invention relates to a slope device for arranging on the lower surface of a step portion formed in a passage to eliminate the step portion and form a ramp that is easy to pass.

従来、この種のスロープ装置としては、例えば特許文献１に示すような、上段面に対して低い段差の下段面に配置され、この下段面と上段面との間にスロープを形成するスロープ装置（段差通路）が知られている。 Conventionally, as this type of slope device, for example, as shown in Patent Document 1, a slope device (as shown in Patent Document 1) which is arranged on a lower step surface having a lower step with respect to an upper step surface and forms a slope between the lower step surface and the upper step surface. Stepped passage) is known.

このスロープ装置は、下段面に配置される台座と、この台座の一端部に基端部で回動自在に装着される本体部を備える布板と、本体部に回動自在に装着される第１の伸縮部材、台座に回動自在に装着されると共に第１の伸縮部材に対して軸方向に移動自在の第２の伸縮部材、および一方の伸縮部材にネジ結合され第１の伸縮部材と第２の伸縮部材からなる軸方向長さを変化させるネジ部材を有する伸縮機構を有し、段差に応じて布板の傾斜角度を変化させることができるものである。 This slope device includes a pedestal arranged on a lower surface, a cloth plate having a main body portion rotatably mounted at one end of the pedestal at a base end portion, and a rotatably mounted main body portion. 1 elastic member, a second elastic member rotatably mounted on a pedestal and movable in the axial direction with respect to the first elastic member, and a first elastic member screwed to one elastic member. It has an expansion / contraction mechanism having a screw member that changes the axial length of the second expansion / contraction member, and can change the inclination angle of the cloth plate according to the step.

特許第４０９４５６１号公報Japanese Patent No. 4094561

ところで、上述した従来のスロープ装置の伸縮機構は、第２の伸縮部材が雄ネジ（ボルト）であり、第１の伸縮部材はこのボルトが摺動自在に挿入される収容部材であり、また、ネジ部材は第２の伸縮部材であるボルトにネジ結合するナットであり、ボルトに対するナットの締結位置を変化させることにより収容部材に対するボルトの挿入量を変化させることができ、収容部材の一端部がナットに当接することにより、布板の傾斜角度を保持することができるように構成されている。 By the way, in the expansion / contraction mechanism of the conventional slope device described above, the second expansion / contraction member is a male screw (bolt), and the first expansion / contraction member is an accommodating member into which this bolt is slidably inserted. The screw member is a nut that is screw-coupled to a bolt that is a second telescopic member, and the amount of bolt inserted into the accommodating member can be changed by changing the fastening position of the nut with respect to the bolt. It is configured so that the inclination angle of the cloth plate can be maintained by contacting with the nut.

しかしながら、上述のような伸縮機構を用いた従来のスロープ装置では、布板にかかる荷重が全て収容部材の一端部とナットとの当接部に集中し、その反作用でボルトのネジ山にナットからの大きな荷重がかかってしまうため、ボルトのネジ山が破損したりボルト自体が破損してしまう懸念がある。 However, in the conventional slope device using the expansion / contraction mechanism as described above, all the load applied to the cloth plate is concentrated on the contact portion between one end of the accommodating member and the nut, and the reaction is caused from the nut to the screw thread of the bolt. Since a large load is applied to the bolt, there is a concern that the screw thread of the bolt may be damaged or the bolt itself may be damaged.

また、従来のスロープ装置の構造では、布板と台座の長さを同等にした場合、布板の傾斜角度を調整するために布板を上方回動操作するほど、布板の先端部分は後方に移動してしまう。そのため、布板が上段面に届かず布板先端部と上段面との間に隙間が生じてしまうことから、従来のスロープ装置は、布板の先端部に前方に突出する延長板部（特許文献１では積層部と称す）が設けられている。 Further, in the structure of the conventional slope device, when the lengths of the cloth plate and the pedestal are made the same, the tip portion of the cloth plate is moved backward enough to rotate the cloth plate upward in order to adjust the inclination angle of the cloth plate. Will move to. Therefore, the cloth plate does not reach the upper surface and a gap is created between the tip of the cloth plate and the upper surface. Therefore, the conventional slope device has an extension plate portion (patented) that projects forward to the tip of the cloth plate. In Document 1, it is referred to as a laminated portion).

しかしながら、このような延長板部（積層部）があることで、この延長板部が突起物となり運搬・設置作業時にこの延長板部に作業者が引っ掛かったりぶつかったりするおそれがある等の安全性の面で懸念があり、更に、スロープ装置を段差部に設置する、布板と台座が重なり合う収納状態では、この延長板部が段差部の段差面（垂直面）に干渉してしまい台座先端部を段差部の段差面に突き当てる状態で設置できないため、設置する前に一々布板を一端上方回動操作して段差面と干渉しない上段面よりも高い位置に移動させなければならず、設置時の作業性が悪いものであった。 However, due to the presence of such an extension plate portion (laminated portion), the extension plate portion becomes a protrusion, and there is a risk that the operator may be caught or hit by the extension plate portion during transportation and installation work. In addition, when the slope device is installed on the stepped portion and the cloth plate and the pedestal overlap each other, this extension plate portion interferes with the stepped surface (vertical surface) of the stepped portion and the tip of the pedestal. Since it cannot be installed in a state where it is in contact with the stepped surface of the stepped portion, the cloth plate must be rotated upward at one end to move it to a position higher than the upper stepped surface that does not interfere with the stepped surface. The workability at the time was bad.

本発明は、このような従来のスロープ装置の問題に鑑みなされたものであり、容易に設置が可能であると共に、荷重が特定の箇所に集中することが無く、荷重集中による部材の破損等のおそれがない実用性に優れたスロープ装置を提供することを目的とする。 The present invention has been made in view of the problem of such a conventional slope device, and the present invention can be easily installed, the load is not concentrated on a specific place, and the member is damaged due to the load concentration. It is an object of the present invention to provide a highly practical slope device without fear.

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。 Embodiments of the present invention which are considered to be suitable will be briefly described by showing the operation of the present invention based on the drawings.

本発明は、一端部がスロープ板部２に回動自在に連結され他端部が本体部１に沿って前後方向に水平移動する第一リンク部材５と、一端部が本体部１に回動自在に連結され他端部が第一リンク部材５の長手方向途中に回動自在に連結される第二リンク部材６とからなるスコットラッセルリンク機構に構成されるスロープ板支持機構３で支持されているから、傾斜状態のスロープ板部２に作用する荷重を、スロープ板支持機構３の第一リンク部材５側と第二リンク部材６側との双方で受けることとなり、これにより、荷重が分散されて特定箇所への応力の集中が緩和され、スロープ板支持機構３及びスロープ板傾斜保持機構４への負荷が軽減されることとなり、これらを構成する部材が破損する等の不具合の発生が低減することとなる。 In the present invention, one end is rotatably connected to the slope plate 2, the other end of the first link member 5 moves horizontally along the main body 1 in the front-rear direction, and one end is rotated to the main body 1. It is supported by a slope plate support mechanism 3 configured by a Scott Russell link mechanism including a second link member 6 which is freely connected and whose other end is rotatably connected in the middle of the longitudinal direction of the first link member 5. Therefore, the load acting on the inclined plate portion 2 is received by both the first link member 5 side and the second link member 6 side of the slope plate support mechanism 3, whereby the load is distributed. The concentration of stress on a specific location is alleviated, the load on the slope plate support mechanism 3 and the slope plate inclination holding mechanism 4 is reduced, and the occurrence of problems such as damage to the members constituting these is reduced. It will be.

即ち、特許文献１に示す従来例は、本発明のスロープ板部２に相当する布板にかかる荷重が全て本発明のスロープ板傾斜保持機構４に相当する収容部材の一端部とナットとの当接部に集中する構成となっているので、ボルトのネジ山にナットからの大きな荷重がかかり、ネジ山が破損する懸念があるが、本発明は、スロープ板部２に作用する荷重は、このスロープ板部２を支持するスロープ板支持機構３に作用することとなり、このスロープ板支持機構３に作用する荷重は、第一リンク部材５を介して、この第一リンク部材５の移動端部５Ａの移動を阻止するスロープ板傾斜保持機構４と、第二リンク部材６の本体部１との回動連結部６Ａ（本体部１と、この本体部１に回動自在に設けられる端部との係合部）に分かれて作用するので、このスロープ板傾斜保持機構４及び第二リンク部材６の回動連結部６Ａには従来例のような大きな荷重が作用せず、これにより、部材の破損が生じる可能性が可及的に低減されることとなる。 That is, in the conventional example shown in Patent Document 1, the load applied to the cloth plate corresponding to the slope plate portion 2 of the present invention is all the contact between one end of the accommodating member corresponding to the slope plate tilt holding mechanism 4 of the present invention and the nut. Since the structure is concentrated on the contact portion, a large load from the nut is applied to the screw thread of the bolt, and there is a concern that the screw thread may be damaged. However, in the present invention, the load acting on the slope plate portion 2 is this. It acts on the slope plate support mechanism 3 that supports the slope plate portion 2, and the load acting on the slope plate support mechanism 3 passes through the first link member 5 and the moving end portion 5A of the first link member 5. A rotation connecting portion 6A (main body portion 1 and an end portion rotatably provided on the main body portion 1) between the slope plate tilt holding mechanism 4 for preventing the movement of the main body portion 6 and the main body portion 1 of the second link member 6 Since it acts separately on the engaging portion), a large load as in the conventional example does not act on the rotary connecting portion 6A of the slope plate tilt holding mechanism 4 and the second link member 6, thereby damaging the member. Will be reduced as much as possible.

また、本発明は、上述したように、スロープ板部２を傾斜角度調整自在に支持するスロープ板支持機構３がスコットラッセルリンク機構であるから、スロープ板部２の傾斜角度を調整するために（スロープ板部２を段差部の上段面の高さ位置に合わせるために）スロープ板部２の先端部側を上下方向に移動操作した際に、このスロープ板部２の先端部が前後方向に位置ずれ移動することなく垂直方向に直線的に移動することとなる。 Further, as described above, in the present invention, since the slope plate support mechanism 3 that supports the slope plate portion 2 so as to be able to adjust the inclination angle is the Scott Russell link mechanism, in order to adjust the inclination angle of the slope plate portion 2 ( When the tip side of the slope plate 2 is moved in the vertical direction (to align the slope plate 2 with the height position of the upper surface of the step), the tip of the slope plate 2 is positioned in the front-rear direction. It will move linearly in the vertical direction without shifting.

したがって、本発明を段差部に設置する際は、段差部の下段面に本体部１を載置し、この本体部１及びスロープ板部２の先端部を段差部の垂直面に突き当てて位置決め状態にした後に、スロープ板部２の先端部を持ち上げ操作して段差部の高さに対応する傾斜状態に調整しても、スロープ板部２の先端部が段差部の垂直面に干渉して上下方向に移動操作することができないといったことがなく、また、スロープ板部２の先端部と段差部の上段面の先端部との間に隙間が生ずることもないので、スロープ板部２の傾斜角度調整した後、再度、設置位置を調整する必要がなく、ゆえに、容易に設置することができる。 Therefore, when the present invention is installed in the stepped portion, the main body portion 1 is placed on the lower surface of the stepped portion, and the tip portions of the main body portion 1 and the slope plate portion 2 are abutted against the vertical surface of the stepped portion for positioning. Even if the tip of the slope plate 2 is lifted and adjusted to an inclined state corresponding to the height of the step after the state is set, the tip of the slope plate 2 interferes with the vertical surface of the step. Since there is no possibility that the slope plate portion 2 cannot be moved in the vertical direction and there is no gap between the tip portion of the slope plate portion 2 and the tip portion of the upper step surface of the step portion, the slope plate portion 2 is tilted. After adjusting the angle, it is not necessary to adjust the installation position again, and therefore the installation can be easily performed.

即ち、特許文献１に示す従来例は、本発明のスロープ板部２に相当する布板の基端部が本発明の本体部１に相当する台座に枢着され、布板が台座に対して回動動作する構成となっているので、布板の先端部は円弧を描くように移動することとなり、これにより、布板の先端部を上方に持ち上げ操作した場合、この布板の先端部は上方に移動するに連れ後方にも移動することとなり、持ち上げ操作前に比べて布板の先端部は後方側に位置することとなり、これにより、例えば、布板の先端部を段差部の垂直面に突き当てて位置決めした状態から、布板の傾斜角度を段差部に合わせて調整すると、布板の先端部と段差部の上段面先端部との間に隙間が生じてしまうので、この隙間を埋めるべく延長板部（積層部）が必要となり、この延長板部（積層部）を設けることで、この延長板部が突起物となり運搬・設置作業時にこの延長板部に作業者が引っ掛かったりぶつかったりするおそれがある等の安全性の面で懸念が生じたり、スロープ装置を段差部に設置する際に、布板と台座が重なり合う収納状態では、この延長板部が段差部の段差面（垂直面）に干渉してしまい台座先端部を段差部の段差面に突き当てる状態で設置できないため、設置する前に一々布板を一端上方回動操作して段差面と干渉しない上段面よりも高い位置に移動させなければならず、作業効率を低下させていたが、本発明は、前述のとおり、スロープ板部２の先端部を段差部の垂直面に突き当てて位置決め状態にした後に、スロープ板部２の先端部を持ち上げ操作して段差部の高さに対応する傾斜状態に調整しても、スロープ板部２の先端部と段差部の上段面の先端部との間に隙間が生じないので、スロープ板部２の先端部に従来例のような延長板部（積層部）を設ける必要がなく、ゆえに、従来例のように、運搬・設置作業時にこの延長板部が作業者に引っ掛かったりぶつかったりするおそれがなく、また、前述のとおり、スロープ板部２の傾斜角度調整した後、再度、設置位置を調整する必要がないので、設置作業が容易となる。 That is, in the conventional example shown in Patent Document 1, the base end portion of the cloth plate corresponding to the slope plate portion 2 of the present invention is pivotally attached to the pedestal corresponding to the main body portion 1 of the present invention, and the cloth plate is attached to the pedestal. Since it is configured to rotate, the tip of the cloth plate moves in an arc, so that when the tip of the cloth plate is lifted upward, the tip of the cloth plate will move. As it moves upward, it also moves to the rear, and the tip of the cloth plate is located on the rear side compared to before the lifting operation. If the tilt angle of the cloth plate is adjusted according to the stepped portion from the state where it is positioned against the cloth plate, a gap will be created between the tip of the cloth plate and the tip of the upper surface of the stepped portion. An extension plate part (laminated part) is required to fill it, and by providing this extension plate part (laminated part), this extension plate part becomes a protrusion and the worker gets caught or bumps into this extension plate part during transportation and installation work. In the stored state where the cloth plate and the pedestal overlap when the slope device is installed on the stepped portion, this extension plate portion is the stepped surface (vertical) of the stepped portion. Since it interferes with the surface) and cannot be installed with the tip of the pedestal abutting against the step surface of the step, it is higher than the upper surface that does not interfere with the step surface by rotating the cloth plate one by one before installation. It had to be moved to a position, which reduced the work efficiency. However, as described above, in the present invention, after the tip of the slope plate 2 is abutted against the vertical surface of the stepped portion to be positioned, the slope is placed. Even if the tip of the plate 2 is lifted and adjusted to an inclined state corresponding to the height of the step, a gap is created between the tip of the slope plate 2 and the tip of the upper surface of the step. Therefore, it is not necessary to provide an extension plate portion (laminated portion) at the tip of the slope plate portion 2 as in the conventional example. Therefore, as in the conventional example, this extension plate portion is used by the operator during transportation and installation work. There is no risk of being caught or bumped, and as described above, it is not necessary to adjust the installation position again after adjusting the inclination angle of the slope plate portion 2, so that the installation work becomes easy.

A portion 8 is provided, and the stopper locking portion 8 abuts and engages with the stopper portion 7 to prevent the first link member 5 from moving due to the downward movement of the slope plate portion 2 of the moving end portion 5A. It is configured to maintain the inclined state of the slope plate portion 2.

より具体的には、本実施例のストッパー部７は、前後方向に延設される貫通孔を有する箱状に形成され、前述したように本体部１の立壁部12に設けられている。 More specifically, the stopper portion 7 of the present embodiment is formed in a box shape having a through hole extending in the front-rear direction, and is provided on the vertical wall portion 12 of the main body portion 1 as described above.

The position adjustment guide unit 15 that moves horizontally in the front-rear direction is provided so that the position can be adjusted and moved.

The bolt tip end side is inserted into the through hole of the stopper portion 7 described above, and is guided by this through hole to horizontally move in the front-rear direction together with the moving end portion 5A.

尚、本実施例では、ボルト・ナットを用いてストッパー係止部８を移動可能とする構成とされているが、ストッパー係止部８を移動させず、ストッパー部７が前後方向に移動する構成とし、このストッパー部７の位置を変更することでストッパー係止部８のストッパー部７に当接係止するタイミングを変更しスロープ板部２の傾斜角度を変更する構成としても良い。 In this embodiment, the stopper locking portion 8 can be moved by using bolts and nuts, but the stopper locking portion 8 is not moved and the stopper portion 7 moves in the front-rear direction. By changing the position of the stopper portion 7, the timing of contact and locking with the stopper portion 7 of the stopper locking portion 8 may be changed, and the inclination angle of the slope plate portion 2 may be changed.

また、本実施例は、上述のように構成されるスロープ板支持機構３の第一リンク部材５の移動端部５Ａの移動をガイドすると共にこの移動端部５Ａの移動範囲を規制し、スロープ板部２の傾斜角度調整範囲を規制する傾斜角度調整範囲規制機構11が備えられており、本実施例の傾斜角度調整範囲規制機構11は、スロープ板支持機構３の第一リンク部材５の移動端部５Ａと共に移動する移動部材11Ａと、この移動部材11Ａの移動範囲を規制する移動範囲規制部11Ｂとからなる構成とされている。 Further, in this embodiment, the movement of the moving end portion 5A of the first link member 5 of the slope plate supporting mechanism 3 configured as described above is guided, and the moving range of the moving end portion 5A is restricted, and the slope plate is regulated. The tilt angle adjustment range regulation mechanism 11 for regulating the tilt angle adjustment range of the portion 2 is provided, and the tilt angle adjustment range regulation mechanism 11 of the present embodiment is a moving end of the first link member 5 of the slope plate support mechanism 3. It is composed of a moving member 11A that moves together with the portion 5A and a moving range regulating portion 11B that regulates the moving range of the moving member 11A.

具体的には、本実施例は、前述した第一リンク部材５の移動端部５Ａに位置調整ガイド部15としてのボルト15（このボルト15が設けられる回動部材16）を回動自在に設けるための第二回動軸を移動部材11Ａとする構成とされ、この第二回動軸11Ａは、図示するように、左右のスロープ板支持機構３間に架設状態に設けられる構成とされ、また、移動範囲規制部11Ｂは、本体部１の立壁部12の長手方向に沿った横長孔に形成されていて、移動部材11Ａとなる第二回動軸11Ａが挿通配設され、この第二回動軸11Ａの移動を案内すると共に、この第二回動軸11Ａの移動範囲を規制する構成とされている。 Specifically, in this embodiment, a bolt 15 (rotating member 16 to which the bolt 15 is provided) as a position adjusting guide portion 15 is rotatably provided at the moving end portion 5A of the first link member 5 described above. The second rotating shaft for this purpose is configured to be a moving member 11A, and the second rotating shaft 11A is configured to be provided in an erected state between the left and right slope plate support mechanisms 3 as shown in the figure. The movement range restricting portion 11B is formed in a horizontally long hole along the longitudinal direction of the vertical wall portion 12 of the main body portion 1, and the second rotation shaft 11A serving as the moving member 11A is inserted and arranged. It is configured to guide the movement of the moving shaft 11A and regulate the moving range of the second rotating shaft 11A.

即ち、本実施例の傾斜角度調整範囲規制機構11は、スロープ板支持機構３の第一リンク部材５の移動端部５Ａに設けられる第二回動軸11Ａと、本体部１に設けられる横長ガイド孔11Ｂとからなる構成とされ、スロープ板部２の傾斜角度調整時にスロープ板支持機構３の第一リンク部材５の移動端部５Ａの移動に伴って第二回動軸11Ａが横長ガイド孔11Ｂ内を移動する構成とされているが、この第二回動軸11Ａは、スロープ板部２の傾斜角度調整に伴う移動において、横長ガイド孔11Ｂの長さ分しか移動できず、この第二回動軸11Ａが横長ガイド孔11Ｂによって移動範囲を制限されることで、この第二回動軸11Ａが設けられる第一リンク部材５の移動端部５Ａの移動範囲が制限（規制）され、この第一リンク部材５の移動端部５Ａの移動範囲が制限（規制）されることで、スロープ板部２の傾斜角度調整範囲を規制する構成とされている。 That is, the tilt angle adjustment range regulating mechanism 11 of this embodiment has a second rotating shaft 11A provided at the moving end portion 5A of the first link member 5 of the slope plate support mechanism 3 and a horizontally long guide provided at the main body portion 1.

Although it is configured to move inside, this second rotation shaft 11A can move only by the length of the horizontally long guide hole 11B in the movement accompanying the adjustment of the inclination angle of the slope plate portion 2, and this second rotation. Since the moving shaft 11A is limited in the moving range by the horizontally long guide hole 11B, the moving range of the moving end portion 5A of the first link member 5 provided with the second rotating shaft 11A is limited (regulated). By limiting (regulating) the moving range of the moving end portion 5A of the one-link member 5, the tilt angle adjusting range of the slope plate portion 2 is regulated.

以上のように構成される本実施例の作用効果について以下に説明する。 The action and effect of this example configured as described above will be described below.

本実施例のスロープ装置を用いて、通路に形成される段差部を解消し通行し易い傾斜路を形成する場合、まず、本実施例を段差部の下段面に設置し、先端部を段差部の垂直面に突き当てて位置決め状態し、この位置決めした状態からスロープ板部２の先端部側を持ち上げ段差部の上段面の高さに合う傾斜状態にする。 When using the slope device of this embodiment to eliminate the stepped portion formed in the passage and form a ramp that is easy to pass through, first, this embodiment is installed on the lower step surface of the stepped portion, and the tip portion is set on the stepped portion. The position is set by abutting against the vertical surface of the above, and the tip side of the slope plate portion 2 is lifted from this positioned state so as to be in an inclined state that matches the height of the upper surface of the step portion.

次いで、スロープ板傾斜保持機構４のストッパー係止部８となるナット８がストッパー部７に当接するようにこのナット８を螺動（移動）させる。 Next, the nut 8 to be the stopper locking portion 8 of the slope plate tilt holding mechanism 4 is screwed (moved) so as to come into contact with the stopper portion 7.

このナット８がストッパー部７に当接係止することで、スロープ板支持機構３の第一リンク部材５の移動端部５Ａの移動が抑制されて、スロープ板支持機構３のスロープ板部２を下方に移動させる動作が抑制され、これによりスロープ板部２の下がり動作が抑制されて、段差部の上段面の高さに合わせた傾斜角度（傾斜状態）が保持され、段差部に傾斜路が形成される。 By abutting and locking the nut 8 to the stopper portion 7, the movement of the moving end portion 5A of the first link member 5 of the slope plate supporting mechanism 3 is suppressed, and the slope plate portion 2 of the slope plate supporting mechanism 3 is suppressed. The operation of moving downward is suppressed, thereby suppressing the downward operation of the slope plate portion 2, the inclination angle (inclined state) according to the height of the upper surface of the step portion is maintained, and the inclined path is formed in the step portion. It is formed.

この設置作業において、本実施例は、スロープ板部２がスコットラッセルリンク機構に構成されるスロープ板支持機構３で支持されているから、スロープ板部２を段差部の上段面の高さ位置に合わせるためにスロープ板部２の先端部側を上方向に移動操作する際に、図示するように、このスロープ板部２の先端部が前後方向に位置ずれ移動することなく垂直方向に直線的に移動するので、スロープ板部２の先端部が段差部の垂直面に干渉して上下方向に移動操作することができないといったことがなく、また、スロープ板部２の先端部と段差部の上段面の先端部との間に隙間が生ずることもないので、スロープ板部２の傾斜角度調整した後、再度、設置位置を調整する必要がなく、ゆえに、容易に設置することができることとなる。 In this installation work, in this embodiment, since the slope plate portion 2 is supported by the slope plate support mechanism 3 configured by the Scott Russell link mechanism, the slope plate portion 2 is placed at the height position of the upper surface of the step portion. When the tip end side of the slope plate portion 2 is moved upward for alignment, as shown in the figure, the tip portion of the slope plate portion 2 is linearly linear in the vertical direction without being displaced in the front-rear direction. Since it moves, the tip of the slope plate 2 does not interfere with the vertical surface of the step and cannot be moved in the vertical direction, and the tip of the slope plate 2 and the upper surface of the step do not occur. Since there is no gap between the slope plate portion 2 and the tip portion of the slope plate portion 2, it is not necessary to adjust the installation position again after adjusting the inclination angle of the slope plate portion 2, and therefore the installation can be easily performed.

また更に、このスロープ板部２がスコットラッセルリンク機構に構成されるスロープ板支持機構３で支持されることで、傾斜状態のスロープ板部２に作用する荷重を、スロープ板支持機構３の第一リンク部材５側に設けられるストッパー部７とこのストッパー部７に当接係止するストッパー係止部８（ナット８）と、第二リンク部材６の本体部１と連結される回動連結部６Ａとの双方で受けることとなり、これにより、荷重が分散されて従来のように応力が一点に集中することが緩和され、スロープ板支持機構３及びスロープ板傾斜保持機構４への負荷が軽減されることとなり、これらを構成する部材が破損する等の不具合の発生が低減することとなる。 Furthermore, since the slope plate portion 2 is supported by the slope plate support mechanism 3 configured by the Scott Russell link mechanism, the load acting on the slope plate portion 2 in the inclined state is applied to the first slope plate support mechanism 3. A stopper portion 7 provided on the link member 5 side, a stopper locking portion 8 (nut 8) that abuts and engages with the stopper portion 7, and a rotary connecting portion 6A connected to the main body portion 1 of the second link member 6. As a result, the load is distributed and the stress is alleviated from being concentrated at one point as in the conventional case, and the load on the slope plate support mechanism 3 and the slope plate inclination holding mechanism 4 is reduced. As a result, the occurrence of problems such as damage to the members constituting these is reduced.

このように、本実施例は、容易に設置が可能であると共に、荷重が特定の箇所に集中することが無く、荷重集中による部材の破損等のおそれがない実用性に優れたスロープ装置となる。 As described above, this embodiment is a highly practical slope device that can be easily installed, the load is not concentrated on a specific place, and there is no risk of damage to members due to the load concentration. ..

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。 The present invention is not limited to the present embodiment, and the specific configuration of each constituent requirement can be appropriately designed.
