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、従来品と同様に、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が発生するおそれが可及的に低減される。 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, as in the conventional product, 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. As a result, the load is dispersed, the concentration of stress on a specific location is eased, the load on the slope plate support mechanism 3 is reduced, and there is a possibility that problems such as damage to the members constituting these may occur. It is reduced.

また、スロープ板支持機構3がスコットラッセルリンク機構に構成されることにより、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の前端部側を上方に移動操作した際に、このスロープ板部2の前端部、すなわち上段面係止板部7が後方向(スロープ装置の基端側)に殆ど位置ずれ移動することなく略垂直方向に直線的に移動することとなり、これにより、上段面係止板部7が段差部の上段面から遠ざからず上段面係止板部7を確実に段差部の上段面に係止させることができる。 Further, since the slope plate support mechanism 3 is configured as a Scott Russell link mechanism, in order to adjust the inclination angle of the slope plate portion 2 (to align the slope plate portion 2 with the height position of the upper surface of the step portion). ), When the front end portion side of the slope plate portion 2 is moved upward, the front end portion of the slope plate portion 2, that is, the upper surface locking plate portion 7 is almost positioned in the rear direction (base end side of the slope device). The upper step surface locking plate portion 7 does not move linearly in a substantially vertical direction without shifting, so that the upper step surface locking plate portion 7 does not move away from the upper step surface of the step portion and the upper step surface locking plate portion 7 is reliably moved to the step portion. It can be locked to the upper surface.

また、本発明は、傾斜状態のスロープ板部2の前端部に設けられた上段面係止板部7が段差部の上段面に係止しこの上段面に支持されることとなり、また、この上段面係止板部7よりも内側でスロープ板支持機構3がスロープ板部2を支持しているから、スロープ板部2は、少なくともスロープ板支持機構3と段差部の上段面の二箇所で支持されることとなり、従来例に比べてスロープ板部2に対する支持力が向上し、スロープ板部2が変形しにくくなるなど優れた耐久性を発揮するスロープ装置となる。 Further, in the present invention, the upper step surface locking plate portion 7 provided at the front end portion of the inclined plate portion 2 is locked to the upper step surface of the stepped portion and is supported by the upper step surface. Since the slope plate support mechanism 3 supports the slope plate portion 2 inside the upper surface locking plate portion 7, the slope plate portion 2 is provided at least at two locations, the slope plate support mechanism 3 and the upper stage surface of the step portion. It will be supported, and the support force for the slope plate portion 2 will be improved as compared with the conventional example, and the slope plate portion 2 will be less likely to be deformed, resulting in a slope device exhibiting excellent durability.

またさらに、本発明のスロープ板部2は、裏面に補強部材8が設けられているから、この補強部材8によりスロープ板部2の耐久性が向上し、しかも、本発明は、上段面係止板部7がスロープ板部2と別体になっていて、この上段面係止板部7は、基端部に補強部材8と重合する取付け用重合部9が突設され、この取付け用重合部9を補強部材8に重合させて取り付けられる構成とされているから、補強部材8に取付け用重合部9が重合されることで補強部材8がより強固なものとなり、より一層スロープ板部2の耐久性が向上し、優れた耐久性を発揮するスロープ装置となる。 Further, since the slope plate portion 2 of the present invention is provided with the reinforcing member 8 on the back surface, the durability of the slope plate portion 2 is improved by the reinforcing member 8, and moreover, the present invention locks the upper stage surface. The plate portion 7 is a separate body from the slope plate portion 2, and the upper surface locking plate portion 7 has a mounting polymerization portion 9 projecting from the base end portion to polymerize with the reinforcing member 8, and this mounting polymerization is performed. Since the portion 9 is polymerized and attached to the reinforcing member 8, the reinforcing member 8 becomes stronger by superimposing the mounting overlapping portion 9 on the reinforcing member 8, and the slope plate portion 2 is further formed. It is a slope device that has improved durability and exhibits excellent durability.

このように、本発明は、特に大きな負荷がかかり劣化破損しやすいスロープ板部2の前側が強固に補強されているから、従来例よりも優れた耐久性を発揮する画期的なスロープ装置となる。 As described above, the present invention is an epoch-making slope device exhibiting superior durability as compared with the conventional example because the front side of the slope plate portion 2 which is easily deteriorated and damaged due to a particularly large load is strongly reinforced. Become.

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.

本実施例は、スロープ板部2(第一スロープ板部2a)を支持するスロープ板支持機構3にスコットラッセルリンク機構を採用したから、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が発生するおそれが可及的に低減される。 In this embodiment, since the Scott Russell link mechanism is adopted for the slope plate support mechanism 3 that supports the slope plate portion 2 (first slope plate portion 2a), the load acting on the slope plate portion 2 in the inclined state is applied to the slope plate. It is received by both the first link member 5 side and the second link member 6 side of the support mechanism 3, whereby the load is dispersed and the concentration of stress on a specific place is alleviated, and the slope plate support mechanism 3 is reached. The load is reduced, and the possibility of problems such as damage to the members constituting these is reduced as much as possible.

また、本実施例は、スロープ板支持機構3がスコットラッセルリンク機構に構成されることにより、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の前端部側を上方に移動操作した際に、このスロープ板部2の前端部、すなわち上段面係止板部7が後方向(スロープ装置の後端部側)に殆ど位置ずれ移動することなく略垂直方向に直線的に移動することとなり、これにより、スロープ板部2を傾斜状態にしても上段面係止板部7が段差部の上段面から遠ざからず上段面係止板部7を確実に段差部の上段面に係止させることができる。 Further, in this embodiment, the slope plate support mechanism 3 is configured by the Scott Russell link mechanism, so that the inclination angle of the slope plate portion 2 can be adjusted (the height of the upper surface of the step portion of the slope plate portion 2). When the front end side of the slope plate 2 is moved upward (to match the position), the front end of the slope plate 2, that is, the upper surface locking plate portion 7 moves in the rear direction (rear end of the slope device). The slope plate portion 2 moves linearly in a substantially vertical direction with almost no misalignment to the portion side), so that the upper surface locking plate portion 7 moves from the upper stage surface of the step portion even if the slope plate portion 2 is in an inclined state. The upper surface locking plate portion 7 can be reliably locked to the upper surface of the step portion without moving away.

また、本実施例は、傾斜状態のスロープ板部2の前端部に設けられた上段面係止板部7が段差部の上段面に係止しこの上段面に支持されることとなり、また、この上段面係止板部7よりも内側でスロープ板支持機構3がスロープ板部2を支持しているから、スロープ板部2は、少なくともスロープ板支持機構3と段差部の上段面の二箇所で支持されることとなり、従来例に比べてスロープ板部2に対する支持力が向上し、スロープ板部2が変形しにくくなるなど優れた耐久性を発揮するスロープ装置となる。 Further, in this embodiment, the upper step surface locking plate portion 7 provided at the front end portion of the inclined plate portion 2 is locked to the upper step surface of the stepped portion and is supported by the upper step surface. Since the slope plate support mechanism 3 supports the slope plate portion 2 inside the upper surface locking plate portion 7, the slope plate portion 2 has at least two locations, the slope plate support mechanism 3 and the upper stage surface of the stepped portion. This is a slope device that exhibits excellent durability such that the support force for the slope plate portion 2 is improved and the slope plate portion 2 is less likely to be deformed as compared with the conventional example.

また、本実施例のスロープ板部2(第一スロープ板部2a)は、裏面に補強部材8が設けられているから、この補強部材8によりスロープ板部2の耐久性が向上し、さらに、本実施例は、上段面係止板部7がスロープ板部2と別体になっていて、この上段面係止板部7は、補強部材8と重合する取付け用重合部9が突設され、この取付け用重合部9を補強部材8に重合させて取り付けられる構成とされているから、補強部材8に取付け用重合部9が重合されることで補強部材8が二重構造になり、より強固なものとなり、より一層スロープ板部2の耐久性が向上し、優れた耐久性を発揮するスロープ装置となる。 Further, since the slope plate portion 2 (first slope plate portion 2a) of the present embodiment is provided with the reinforcing member 8 on the back surface, the durability of the slope plate portion 2 is improved by the reinforcing member 8, and further, the durability of the slope plate portion 2 is improved. In this embodiment, the upper surface locking plate portion 7 is a separate body from the slope plate portion 2, and the upper surface locking plate portion 7 is provided with a mounting polymerization portion 9 that polymerizes with the reinforcing member 8. Since the mounting polymerized portion 9 is polymerized and mounted on the reinforcing member 8, the reinforcing member 8 has a double structure due to the polymerization of the mounting polymerized portion 9 on the reinforcing member 8. The slope device becomes stronger, the durability of the slope plate portion 2 is further improved, and the slope device exhibits excellent durability.

また、本実施例は、スロープ板部2の前端部に設けられる上段面係止板部7が着脱自在に設けられているか、この上段面係止板部7に劣化破損が生じた場合でも、この上段面係止板部7を取り外して修理したり新しいものと交換したりして、引き続き使用することができるので、長寿命化が可能な実用性に優れたスロープ装置となる。 Further, in this embodiment, even if the upper surface locking plate portion 7 provided at the front end portion of the slope plate portion 2 is detachably provided or the upper stage surface locking plate portion 7 is deteriorated and damaged. Since the upper surface locking plate portion 7 can be removed and repaired or replaced with a new one for continuous use, the slope device has excellent practicality and can extend the service life.
