Description

[Detailed explanation of the idea] This invention relates to a stair lift device.

First, a conventional stair climbing device will be explained with reference to FIGS. 1 and 2.

In the figure, 1 is a staircase, 2 is a passage perpendicular to the end of the staircase, and 3 is a staircase.
4 is a rail provided corresponding to the length of the staircase 1 and part of the width of the passage 2; 4 is a lifting body movably engaged with the rail 3; and 5 is a rail provided along the movement path of the lifting body 4. This is a handrail placed on the side opposite to the rail 3.

That is, the elevating body 4 is guided by the rails 3 and driven by a driver (not shown) to move between the passage 2 and the upper end of the stairs 1.

Further, in order to make the floor surface of the elevating body 40 substantially coincident with the surface of the passageway 2, it is necessary to provide the rail 3 also in the passageway 2 section.

For this reason, there was a problem that the portion corresponding to the passage 2 at the end of the rail 3 became an obstacle to the passage 2.

This invention solves the above-mentioned drawbacks, and aims to provide a stair lifting device in which the rails that guide the elevator moving on the aisle and stairs do not obstruct the aisle when not in operation.

An embodiment of this invention will be described below with reference to FIGS. 3 to 5.

In the figure, the same reference numerals as in Figures 1 and 2 indicate corresponding parts, 3 is a fixed rail provided at a location corresponding to the length of the staircase 1, 3 is a fixed rail provided at a location corresponding to the passage 2, and one end is the fixed rail 3 end. A movable rail whose longitudinal end is rotated by manual operation and held in a position along the extension line of the fixed rail 3, or along the length of the passage 2; 6a is a normally closed contact,
7 is a controller for the driving machine of the elevating body 4, and (→←) is a power source.

That is, when the elevating body 4 is operated, the movable rail 3' is in the third position.
, as shown in FIG. 4, the elevating body 4 is held on the extension line of the fixed rail 3 and guided at the position shown by the chain line, that is, on the passage 2 surface 1.

Further, at this time, the detection device 6 is not pressed, the contact 6a is closed, and the controller is energized by the circuit (g)-6a-7-(f), and the elevating body 4 becomes ready for operation.

When the movable rail 3 is bent or not in operation, the elevating body 4 is stopped at the upper end position of the stairs 1 as shown by solid lines in FIGS. 3 and 4.
is held at the position shown by the solid line, that is, along the length of the passage 2.

As a result, passage through the passage 4 is not obstructed by the movable rail 3 when the elevating body 4 is not in operation.

Note that when the movable rail 3 is located along the length of the passage 2, the detection device is pressed and the contact point 6a is opened, so that the elevating body 4 is not operated carelessly.

As explained above, this invention provides fixed rails in locations corresponding to stairs and movable rails in locations corresponding to aisles, so that when the elevator is in operation, the elevator can be guided on the aisle surface 1, and when not in operation, the movable rail is installed in the aisle. Since it is disposed at a position facing a longitudinal wall surface, a stair elevating device is realized in which passage through the passage is not obstructed by the rail when the elevating body is not in operation.
