  Hereinafter, a stair lift device according to the present invention will be described with reference to the accompanying drawings.

  The whole structure of the stair lifting device 1 to which the present invention is applied is shown in FIG. The stair lifting device 1 is a traveling rail 20 installed on one side edge of the stair 3 along the stairway 2, a riding device 10 that moves up and down the stair 3 along the traveling rail 20, and drives the riding device 10. Driving means 50 and 51, and a rotating device 30 installed on the upper floor 4 of the staircase passage 2.

  The traveling rail 20 is installed on one side edge of the stairs 3 along the stairs passage 2. The staircase passage 2 has a straight portion 2a that is linear in the ascending / descending direction and a curved portion 2b that is curved in the ascending / descending direction, and the traveling rail 20 includes, for example, two L-shaped steels along the staircase passage 2. They are arranged in parallel with a predetermined interval. Further, in the curved portion 2b, the two L-shaped steels are formed for each stage, and a plate 21 is attached between the two L-shaped steels. The curved portion of the traveling rail 20 is formed by joining the two L-shaped steels.

  The riding equipment 10 moves up and down on the traveling rail 20 in a state where the passenger is boarded downward. As shown in FIG. 2, the riding equipment 10 includes a traveling wheel 11 for traveling along the traveling rail 20 and a seating surface 12 on which a passenger sits, and the seating surface 12 is level with respect to the floor during elevation. Therefore, the rear traveling wheel 11 a is attached to a position close to the seat surface 12, and the front traveling wheel 11 b is attached to a position away from the seat surface 12. As a result, the riding equipment 10 travels on the traveling rail 20 with all the traveling wheels 11 placed on the traveling rail 20. The riding equipment 10 includes a footrest 18. At this time, by attaching the front traveling wheel 11b to the rear of the footrest 18 at substantially the same height as the footrest 18, the position of the seating surface 12 can be lowered and the passenger can get on and off more easily.

  For example, a winch 51 and a wire 50 are used as driving means for the riding equipment 10. The wire hook 13 is attached to the rear center of the riding device 10, the wire 50 is hooked on the wire hook 13, and the wire 50 is wound or loosened by the winch 51, thereby raising and lowering the riding device 10. At this time, the wire fastener 22 is attached to the center of the plate 21 so that the wire 50 passes through the central portion of the traveling rail 20 in the curved portion 2 b of the staircase passage 2. The wire fastener 22 is formed so that the wire 50 can be easily detached when the riding equipment 10 passes through the bending portion 2b. Thereby, even if it is the stairway 2 which has the curved part 2b, the riding implement 10 can be raised / lowered.

  The winch 51 is installed on the upper floor 4 and is operated by a switch 60 provided on each of the upper and lower wall surfaces. The switch 60 has three buttons, up, down, and stop. When the passenger presses the up or down button after boarding the boarding device 10, the boarding device 10 starts to move up and down. On the lower floor side of the traveling rail 20 and the upper floor side of the support rail 36 to be described later, the riding equipment 10 reaches the upper floor and is mounted on the support rail 36 or when the riding equipment 10 reaches the lower floor. When the riding equipment detecting means 61 is attached to the mounting position and the riding equipment 10 is mounted on the riding equipment detecting means 61, the winch 51 is stopped by the control means, and the riding equipment 10 is stopped. Moreover, when trouble occurs, when the assistant pushes the stop button, the riding equipment 10 stops on the spot. At this time, since the staircase 3 is immediately at the feet of the passenger, it is possible to get off the boarding equipment 10 on the spot.

  In addition, the riding equipment 10 has armrests 14 attached substantially horizontally to the floor on both sides, and a safety bar 15 attached to the armrests 14. One of the safety bars 15 is rotatably attached to the armrest portion 14 using, for example, a hinge 19. For example, the L-shaped member 16 is attached to the armrest portion 14 and a hole is formed at a position where the L-shaped member 16 and the safety bar 15 are combined, and the pin 17 is inserted into or removed from the hole. In this way, it is detachably attached. When the removable side of the safety bar 15 is removed, the rotatable side rotates and the safety bar 15 moves upward or outward. The passenger gets on the riding equipment 10 in this state, and then attaches the safety bar 15 to the armrest portion 14. As a result, the safety bar 15 is fixed to the riding equipment 10 and is held by the safety bar 15 when ascending / descending, so that the occupant can use the riding equipment 10 with peace of mind, and is effective in preventing falling during the ascent / descent. The pin 17 is attached to the L-shaped member 16, and the pin is retracted by pulling the knob. When the knob is released, the index plunger returns to the original position by the force of the spring. It can be easily inserted and removed. Moreover, since it is attached to the L-shaped member, it is not lost when it is removed.

  In this embodiment, the winch 51 and the wire 50 are used as the driving means. However, the traveling rail 20 is a pair of racks, and either or both of the front and rear of the traveling wheels 11 are fitted to the rack. It is also possible to move the stairway 2 up and down by mounting a motor that drives the pinion on the riding equipment 10.
