本発明にかかる車両用昇降装置は、車椅子を載置する平板状の載置体を地面上又はその近くの下降位置と車両の床面と同高さ又は略同高さの上昇位置とに平行又は略平行姿勢で昇降操作する昇降操作手段を支持する基枠が、前記昇降操作手段が車両内外方向に出退する車両開口部に臨む床部の上面に載置される状態で、前記床部に取り付けられたものであって、その第１特徴構成は、
前記床部が、板状の床形成部材とその床形成部材の下面に溶接されるフランジ部を備えた長尺状の補強部材とを備えて構成され、前記基枠が、その基枠、前記床形成部材、及び、前記補強部材のフランジ部を共締めするボルトにて前記床部に締め付け固定される状態で、前記床部に取り付けられ、前記フランジ部の下面及びそのフランジ部の側方に位置する前記床形成部材の下面に当て付ける補助部材が、前記ボルトにて、共締め固定されている点にある。 The vehicle lifting apparatus according to the present invention is configured such that a flat plate-like mounting body on which a wheelchair is mounted is parallel to a descending position on or near the ground and an ascending position that is the same height as or substantially the same as the floor surface of the vehicle. Or a base frame that supports a lifting operation means that lifts and lowers in a substantially parallel posture is placed on the upper surface of the floor facing the vehicle opening where the lifting operation means moves in and out of the vehicle. The first characteristic configuration is attached to
The floor portion includes a plate-like floor forming member and a long reinforcing member having a flange portion welded to the lower surface of the floor forming member, and the base frame includes the base frame, the base frame, A floor forming member and a bolt that fastens the flange portion of the reinforcing member are fastened and fixed to the floor portion, and are attached to the floor portion, on the lower surface of the flange portion and to the side of the flange portion. The auxiliary member applied to the lower surface of the floor forming member positioned is fixed together with the bolt .

すなわち、床部が、板状の床形成部材とその床形成部材の下面に溶接されるフランジ部を備えた長尺状の補強部材とを備えて構成され、基枠が、その基枠、床形成部材、及び、補強部材のフランジ部を共締めするボルトにて床部に締め付け固定される状態で、床部に取り付けられているから、基枠を、板状の床形成部材に加えて、補強部材のフランジ部に締め付け固定することができるため、基枠を強固に床部に取り付けることができる。
つまり、車両の床形成部材の下面には、補強のための長尺状の補強部材が溶接されることに着目して、その補強部材のフランジ部をも利用して基枠を床部に締め付け固定するようにすることにより、基枠を床部に強固に取り付けることが可能となるのである。
従って、基枠を強固に床部に取り付けることができる車両用昇降装置を提供することができるに至った。 That is, the floor portion is configured to include a plate-like floor forming member and a long reinforcing member having a flange portion welded to the lower surface of the floor forming member, and the base frame is configured to include the base frame, the floor Since it is attached to the floor portion in a state where it is fastened to the floor portion with bolts that tighten the flange portion of the forming member and the reinforcing member together, the base frame is added to the plate-like floor forming member, Since it can be fastened and fixed to the flange portion of the reinforcing member, the base frame can be firmly attached to the floor portion.
In other words, paying attention to the fact that a long reinforcing member for reinforcement is welded to the lower surface of the floor forming member of the vehicle, the base frame is fastened to the floor portion also using the flange portion of the reinforcing member. By fixing, the base frame can be firmly attached to the floor.
Therefore, it has come to be able to provide a vehicle lifting device that can firmly attach the base frame to the floor.

また、前記フランジ部の下面及びそのフランジ部の側方に位置する前記床形成部材の下面に当て付ける補助部材が、前記ボルトにて、共締め固定されているから、補助部材がフランジ部の下面及びそのフランジ部の側方に位置する床形成部材の下面に当て付けられており、載置部を昇降移動させたときに床形成部材にかかる力を、補強部材のフランジ部のみならずそのフランジ部の側方に位置する床形成部材にても分散して受けることができるため、基枠をより強固に床部に取り付けることができる。
従って、基枠をより強固に床部に取り付けることができる車両用昇降装置を提供することができるに至った。 Further , since the auxiliary member applied to the lower surface of the flange portion and the lower surface of the floor forming member located on the side of the flange portion is fastened together with the bolt, the auxiliary member is the lower surface of the flange portion. And a force applied to the floor forming member when the mounting portion is moved up and down, as well as the flange portion of the reinforcing member. Since the floor forming member located on the side of the part can be dispersed and received, the base frame can be more firmly attached to the floor part.

従って、ボルトの装着が行い易く、又、基枠を床部に対して緩み難い状態で締め付け固定することができる車両用昇降装置を提供することができるに至った。 That is, since the bolt is screwed into the female screw member attached to the lower surface of the auxiliary member, it is easy to mount the bolt, and a double nut is formed by this female screw member and a nut screwed into the bolt later. Therefore, the base frame can be fastened and fixed in a state where it is difficult to loosen with respect to the floor.
Therefore, it has become possible to provide an elevating device for a vehicle that can be easily mounted with bolts and can be fastened and fixed in a state in which the base frame is hardly loosened against the floor.

本発明にかかる車両用昇降装置の第３特徴構成は、第１又は第２特徴構成において、前記補助部材が、前記ボルトにて共締めする箇所に、前記床形成部材に螺合するビスにて保持されている点にある。 According to a third characteristic configuration of the vehicle lifting and lowering apparatus according to the present invention, in the first or second characteristic configuration, the auxiliary member is screwed into the floor forming member at a position where the auxiliary member is fastened with the bolt. It is in a held point.

すなわち、補助部材を、ボルトにて共締めする箇所に、床形成部材に螺合するビスにて保持することができるから、床形成部材の上方箇所からボルトを装着する際に、ビスによる保持によって補助部材が保持されているから、一人作業が行い易くなる等、基枠の床部に対する締め付け固定が行い易いものとなる。
従って、基枠の床部に対する締め付け固定が行い易い車両用昇降装置を提供することができるに至った。 That is, since the auxiliary member can be held by a screw screwed to the floor forming member at a location to be fastened with a bolt, when the bolt is mounted from above the floor forming member, Since the auxiliary member is held, it becomes easy to fasten and fix the base frame to the floor, for example, it is easy to work alone.
Therefore, it has come to be able to provide a vehicle elevating device that can be easily fixed to the floor of the base frame.

本発明にかかる車両用昇降装置の第４特徴構成は、第１〜第３特徴構成のいずれか１つにおいて、前記基枠が、前記車両開口部の横幅方向に伸びる横長状に形成されて、その両横端部が前記ボルトにて前記床部に締め付け固定されている点にある。 According to a fourth characteristic configuration of the vehicle lifting apparatus according to the present invention, in any one of the first to third characteristic configurations, the base frame is formed in a horizontally long shape extending in a horizontal width direction of the vehicle opening, The both lateral ends are fastened and fixed to the floor by the bolts.

すなわち、基枠を、車両開口部の横幅方向に伸びる横長状に形成し、その両横端部をボルトにて床部に締め付け固定されているから、基枠は車両横幅方向に間隔を隔てた複数箇所で床部に締め付け固定することができるため、基枠を安定した状態で床部に取り付けることができる。
従って、基枠を安定した状態で床部に取り付けることができる車両用昇降装置を提供することができるに至った。 That is, the base frame is formed in a horizontally long shape extending in the lateral width direction of the vehicle opening, and both lateral ends thereof are fastened and fixed to the floor by bolts, so that the base frame is spaced apart in the vehicle lateral width direction. Since it can be fastened and fixed to the floor portion at a plurality of locations, the base frame can be attached to the floor portion in a stable state.
Therefore, the vehicle elevating device that can be attached to the floor portion in a stable state can be provided.

A plurality of positions are formed by shifting the position in the lateral width direction of the vehicle opening.

すなわち、前記ボルトを挿通する挿通孔が、取り付け位置調整用として、前記車両開口部の横幅方向に位置をずらして複数形成されているから、その複数形成された挿通孔を選択して基枠を床部に取り付けることにより、床部におけるボルトを締め付ける箇所を補強部材のフランジ部から変更することなく、例えば、基枠を車両開口部にその横幅方向の中央部に取り付ける、又は、車両開口部にその横幅方向の右寄りに取り付ける等、基枠を床部に取り付ける際に車両開口部の横幅方向に位置調節することができるため、車両用昇降装置の使い勝手がよいものとなる。
従って、使い勝手のよい車両用昇降装置を提供することができるに至った。 That is, a plurality of insertion holes through which the bolts are inserted are formed by shifting the position in the lateral width direction of the vehicle opening for adjusting the mounting position. By attaching to the floor part, for example, the base frame is attached to the vehicle opening part at the center part in the lateral width direction without changing the location where the bolt in the floor part is tightened from the flange part of the reinforcing member, or to the vehicle opening part. When the base frame is attached to the floor, such as being attached to the right side in the lateral width direction, the position of the vehicle opening can be adjusted in the lateral width direction, which makes the vehicle lifting device easier to use.
