[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a landing device for a carrier in a stair lift.

[0002]

2. Description of the Related Art When a stair lift arrives at an upper floor or a lower floor, a user such as a wheelchair gets on and off unless there is a gap between the bottom of the carrier and the floor. Sometimes it is both difficult and dangerous.

Therefore, as a conventional technique for eliminating the gap, the facing distance between the floor of the arrival floor and the rail is gradually reduced toward the stop position of the carrier, and the traveling speed of the carrier is decelerated immediately before the stop. Then, there is a device in which the gap between the bottom of the carrier and the floor of the arrival floor is eliminated as much as possible when the carrier is stopped.

In this case, considering the fact that the floor of the arrival floor has a slope and the floor of the carrier flexes due to the load, a certain gap is required with respect to the floor of the arrival floor when the carrier stops. Become.

Therefore, there is a problem that the gap cannot be extremely reduced and the device becomes complicated due to the increase and decrease in traveling speed.

[0006] Further, by providing a long wobbling plate which can be raised and lowered freely at the boarding edge of the floor of the carrier, the inclination of the floor surface of the arrival floor and the flexure of the floor of the carrier can be absorbed by the upper and lower parts of the wagon.

However, since the dimension when the bridge plate is opened (when it is grounded) becomes long, various inconveniences occur in the layout of the stair lift in a building.

Further, there is a method in which the bottom of the carrier is lowered after stopping the carrier on the arrival floor. In this case, the structure becomes complicated and the cost increases significantly.

Therefore, the present invention eliminates the gap with an extremely simple structure.

[0010]

In order to solve the above problems, the present invention engages a plurality of support rollers of a carrier with a guide rail provided along a stair so that the support rollers can travel freely.
In a stair lift that allows the carrier to travel by an appropriate drive means, a movable unit that allows tilting of the carrier in the landing direction at a portion that comes into contact with one roller of the carrier stopped at the getting on / off position of the guide rail. Provide a rail part,
Further, a configuration is provided in which a moving action device for the movable rail portion is provided.

[0011]

When the carrier is running, the movable rail is returned to its original position by the action of the action device. That is, the guide rail and the movable rail portion should be on the same line.

When the carrier arrives at the upper floor or the lower floor, the movable rail portion is moved by the action of the operating device, and the bottom edge of the carrier is landed on the floor of the arrival floor.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, a guide rail 4 along the stairs 1 is provided between the upper floor 2 and the lower floor 3 of the stairs 1.

A plurality of rollers 6 supported by the carrier 5 are movably engaged with the guide rail 4 so that the carrier 5 can be moved by an appropriate driving means.

In the illustrated case, the roller 6 is located slightly above the upper floor 2 side and further above the upper floor 2 side from the bisector position between the entrances and exits of the carrier 5 facing the upper floor 2 and the lower floor 3. Bearings at two positions, the upper peripheral surface of the roller 6 on the upper floor 2 side is provided on the lower surface of the upper rail plate portion parallel to the upper and lower sides of the channel steel guide rail 4, and the lower rail plate portion of the guide rail 4 is provided. The lower peripheral surface of the roller 6 on the lower floor 3 side is brought into contact with the upper surface.

The driving means for running the carrying device 5 is a roller 6
In addition to the method of driving the friction wheel by a reduction gear motor (not shown) installed on the carrier 5 and the method of using a pinion and a rack, a chain wheel (not shown)
Carry out according to the driving method.

Further, a portion of the carrier 5 stopped at the getting on / off position of the guide rail 4 in contact with the roller 6 on the upper floor 2 side,
A movable rail portion 7, which allows the carrier 5 to tilt in the landing direction,
7'is provided.

As shown in FIG. 4, the movable rail portions 7 and 7'separate the upper rail plate portion of the guide rail 4 from the guide rail 4, and the separated one end is undulated on the guide rail 4 via a hinge 8. It is rotatably attached.

Further, the movable rail portions 7, 7'are adapted to rotate in the undulating direction by the action of the action device 9.

In the illustrated case, the operating device 9 uses a cylinder whose end is rotatably supported at a fixed position and whose tip is rotatably connected to the movable rail portions 7 and 7 '. Instead, for example, a method of bringing the outer peripheral surface of the cam into contact with the upper surface of the movable rail portion may be adopted.

With the above construction, as shown in FIG. 1, when the carrier 5 stops on the lower floor 3, the movable rail portion 7'is pulled up by the action of the action device 9.

Then, the carrier 5 tilts due to its weight,
As shown in FIG. 2, the bottom of the transporter 5 gets on and off the floor of the lower floor 3.

Further, when the carrier 5 stops on the upper floor 2, the movable rail portion 7 is pushed down by the action of the action device 9.

Then, while the roller 6 is being pushed down, the weight is struck by the weight and the carrier 5 tilts, and the bottom side of the carrier 5 gets on and off the floor of the upper floor 2, as shown in FIG.

When the carrier 5 travels, the movable rail portions 7 and 7'are returned to their original positions so that the guide rail 4 and the movable rail portions 7 and 7'are on the same line before traveling. deep.

In the figure, reference numeral 10 denotes a bridge plate which is provided on the bottom edge of the bottom of the carrier 5 so as to be capable of undulating and rotating.

[0028]

[Effects] Since the carrier landing device according to the present invention is configured as described above, the movable rail portion provided on the guide rail is rotated to land the carrier floor on the upper floor or lower floor. can do.

Therefore, in the layout of the stair climber on the building, it is possible to eliminate the inconvenience that the bridge plate becomes an obstacle and the problem that the cost is remarkably increased by raising and lowering the bottom of the carrier.
