For example, as shown in FIG. 5, a guide rail 3 is mounted along a lateral wall of a staircase, and an elevating and lowering drive body 5 is movably supported along the guide rail 3 by an internal drive source. There is a structure in which a mounting member 6 for mounting and supporting a transported object such as luggage or a physically handicapped person is attached to the upper side of 5, and the mounting surface of the mounting member 6 is
Since it is necessary to provide the guide rail 3 at a position having a predetermined height from the floor surface, the guide rails 3 are provided on both upper and lower sides of the stairs 1.
It was configured to extend and project outward.

[0003]

However, in the above conventional structure, since the guide rail is extended and protrudes from the stairs, for example, in a floor surface portion either above or below the stairs, a direction orthogonal to the stair climbing direction. When there is a corridor in the corridor, there are drawbacks such as the rail portion projecting from the extension is a hindrance to walking, and a pedestrian may get caught, which is dangerous. The present invention aims to eliminate the above-mentioned problems.

[0004]

According to a first aspect of the present invention, in the mounting and elevating apparatus described at the beginning, a supporting arm rotatable about a horizontal axis is pivotally supported on the elevating and lowering drive body. The mounting member is supported by the support arm in a state in which the support arm is maintained in a horizontal posture regardless of the turning operation of the support arm. According to a second aspect of the present invention, in the mounting and elevating device described at the beginning, the elevating drive member and the mounting member are connected via an arm that is extendable and contractible in a direction along the moving direction of the elevating drive member. There is a point.

[0005]

According to the structure of the first aspect of the present invention, even when the elevating / lowering body is stopped in the position-fixed state, the supporting arm is rotated to keep the mounting member within a predetermined range while maintaining the horizontal posture. You can swing up and down with. As a result, even if the guide rail is configured to be short at the end of the stairs so as not to project outward, the mounting member has a proper object mounting surface with respect to the floor surface outside the stairs. It will be possible to set a height for getting on and off. According to the configuration of the second invention, by extending the arm at the end of the stairs, the placing member is moved toward the outside of the end of the rail in the same horizontal posture as that during the lifting operation. Even if the rail is configured to be short so that it does not project outward from the end of the stairs, the mounting member has an appropriate height for the object mounting surface with respect to the floor outside the stairs. It will be possible to set the boarding and alighting state.

[0006]

As a result, it is possible to smoothly perform the placement work of the object to be conveyed at the elevating end portion while the elevating guide rail is provided so as not to project outward from the end portion of the stairs. Even if there is a corridor in the direction perpendicular to the stair climbing direction on the floor part on the outside of the stairs, the rails will not extend and project into this corridor part, which will obstruct walking. It has become possible to prevent the harmful effects such as being caught in the air and being caught by pedestrians.
