BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device, and more particularly to a technique for effectively utilizing a spiral space at the back of a spiral staircase to move people and objects up and down.

0002

2. Description of the Related Art Elevators have conventionally been used to move people and objects up and down, but they require a dedicated space. In some cases, the space of the stairs is used to attach a handrail along the stairs and use this as a guide rail to attach an elevating capsule, and to carry people or objects up and down the elevating capsule.

0003

[Problem to be solved by the invention] However, with such a structure, a part of the space for the stairs is used as a space for going up and down, which greatly reduces the space for the stairs and hinders the ability to go up and down the stairs. There was a problem that sometimes. The present invention was made in view of these problems, and its purpose is to effectively utilize a spiral staircase so that climbing and descending of the spiral staircase is not obstructed, but the back part of the spiral staircase is not obstructed. It is possible to use empty space to move people and objects up and down, and in particular, by using the spiral staircase configuration, equipment costs are kept down, and the height of the elevator capsule can be easily adjusted when ascending from the floor below. To provide a lifting device that makes it convenient to get on and off the stairs.

0004

[Means for Solving the Problems] In the lifting device of the present invention, a guide rail 3 is laid in a spiral along the spiral cavity 2 at the back of the spiral staircase 1, and the lifting capsule 4 can be freely guided by the guide rail 3. The device is characterized in that it is equipped with a drive means 5 which is attached to the guide rail 3 and drives the elevating capsule 4 up and down along the guide rail 3.

[0005]

[Function] In this way, the guide rail 3 is laid in a spiral along the spiral cavity 2 at the back of the spiral staircase 1, the elevating capsule 4 is attached to the guide rail 3 so as to be able to freely guide the elevating capsule 4, and the elevating capsule 4 is attached to the guide rail. 3, the driving means 5 drives the elevator capsule 4 up and down along the guide rail 3 to move people and objects in the spiral space 2 at the back of the spiral staircase 1. In this way, the spiral space 2 at the back of the spiral staircase 1 is transported up and down.
By effectively utilizing the spiral space 2 at the back of the spiral staircase 1 without reducing the staircase space in the spiral staircase 1, space saving is achieved by effectively utilizing the structure of the spiral staircase 1. Equipment costs are kept down, and people and objects can be easily loaded onto the elevating capsule 4 by adjusting the height of the elevating capsule 4 downstairs, making it easy to use.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described in detail below with reference to the drawings. The spiral staircase 1 is constructed with steps 7 spirally climbing around a central support 6, but the design of the spiral staircase 1 can be modified in various ways. A guide rail 3 is laid spirally along the spiral cavity 2 at the back of the spiral staircase 1. Specifically, a pair of rail bodies 3a are attached to the back of the step 7 by welding or the like, and the guide rail 3 is provided in a spiral shape. One rail body 3 of this guide rail 3
A rack gear 8 is formed in the full length of each of a, a stay 9 is extended from the gondola-shaped lifting capsule 4 side, a pinion gear 10 formed with a helical gear is rotatably held on this stay 9, and this pinion gear 10 A motor 11 is used to freely rotate the drive in forward and reverse directions. and guide rail 3
A runner (not shown) attached to the elevating capsule 4 side engages with the other rail body 3a to prevent the elevating capsule 4 from shaking. The configuration of the driving means 5 for the elevating capsule 4 can be modified in various ways.

[0007] Thus, the motor 11 rotates in forward and reverse directions.
The pinion gear 10 is rotationally driven, and the elevating capsule 4 can be driven up and down via the rack gear 8 with which the pinion gear 10 is meshed. in this way,
A guide rail 3 is laid in a spiral along the spiral cavity 2 at the back of the spiral staircase 1, an elevating capsule 4 is attached to the guide rail 3 so as to be freely guided, and the elevating capsule 4 is driven up and down along the guide rail 3. By providing the drive means 5, the elevator capsule 4 is driven up and down along the guide rail 3 by the drive means 5, and people and objects are transported up and down in the spiral space 2 at the back of the spiral staircase 1. In this way, the spiral space 2 at the back of the spiral staircase 1 is effectively used, and the spiral staircase 1
To save space by effectively utilizing the spiral void 2 at the back of the spiral staircase 1 without reducing the space for the stairs, and by utilizing the configuration of the spiral staircase 1, the equipment cost can be reduced.
Moreover, in the downstairs area, people and objects can be easily loaded into the elevating capsule 4 by adjusting the height of the elevating capsule 4.
It also improves usability.

[0008]

Effects of the Invention As described above, the present invention includes a guide rail that is laid in a spiral along the spiral cavity at the back of a spiral staircase, and an ascending and descending capsule is attached to the guide rail so that it can be guided freely.
Since the device is equipped with a driving means for driving the elevating capsule up and down along the guide rail, the elevating capsule is driven up and down along the guide rail by the driving means to transport people and objects up and down in the spiral cavity at the back of the spiral staircase. In this way, the spiral void at the back of the spiral staircase is effectively used to save space without reducing the stair space in the spiral staircase. By using the spiral staircase structure, equipment costs can be reduced, and by adjusting the height of the ascending/descending capsule downstairs, people and objects can be easily loaded into the ascending/descending capsule, making it easy to use. There is an advantage.
