DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair-type inclined lifting device used by a physically handicapped person having difficulty in walking or an elderly person to move upstairs or downstairs.

[0002]

2. Description of the Related Art A chair-type tilting type elevating device is already on the market as an assisting means for a physically handicapped person or an elderly person who has difficulty walking or moving upstairs or downstairs. In these devices, as a driving method, a pinion attached to a motor shaft meshes with a rack attached to a guide rail, and the motor moves up and down as the motor rotates. As described above, the elevating device travels by being guided by the guide rails attached to the floor or the stairs via the mounting columns. FIG. 1 shows an embodiment of a conventional lifting device. As shown in the drawing, the conventional device has a problem that the guide rail occupies a large space in the room, which is a great obstacle to the movement of general pedestrians or luggage. In particular, in a corner portion of a room, a predetermined radius is required so that the elevating device can be rotated, and the indoor space is further narrowed, which becomes an obstacle for the pedestrian and the like.
In addition, since the guide rail is formed of an extruded material, the guide rail becomes expensive, and at the same time, the inclination gradient and the size of the corner R are defined, and the problem that free and effective installation design cannot be performed is included.

[0003]

The object of the present invention is to solve the above-mentioned problems, to maximize the use of the indoor space, not to hinder the movement of ordinary pedestrians or luggage, and to make the guide rails without embossing materials. It is an object of the present invention to provide a chair-type tilting type elevating device which is inexpensive and whose tilt angle and corner turning angle can be selected relatively arbitrarily.

[0004]

The present invention employs an endless track in which a large number of permanent magnets are arranged on a guide rail installation surface in a drive method, instead of a conventional rack and pinion method, as a drive method of a chair type tilting type elevating device. Uses an iron plate. When the lifting device moves, a plurality of permanent magnets attached to the grounding surface travel while sequentially attracting to the iron rail.

[0005]

Therefore, according to the present invention, a column or the like for mounting the guide rail is unnecessary, and the indoor space can be utilized to the maximum.
It does not hinder the movement of ordinary pedestrians or luggage, and enables the whole family, including people with mobility impairments and ordinary people, to be able to spend a comfortable day. Further, the angle of the stairs and the like and the corner angle can be freely selected at the time of construction, and the maximum utilization effect can be obtained at the time of architectural design.

[0006]

Next, examples of the present invention will be described. FIG. 2 shows an embodiment of the chair type tilting type elevating device of the present invention. The chair-type inclined lifting device is roughly divided into a chair part and a drive mechanism part.
It consists of 5 ▼. The chair is provided with a structure in which a disabled person or an elderly person who intends to move upstairs or downstairs using the present device can sit safely and perform a driving operation. Driving operation can be performed by operating switches, such as a sleeve of a chair, which are arranged at an easy-to-operate position. The drive mechanism (15) has a tilt adjustment unit,
It is composed of a drive unit and a control unit. The inclination adjustment unit has a function of adjusting the inclination angle of the seat so that the occupant always keeps the vertical position when the elevating device moves from the flat portion to the inclined portion. The drive unit has a function of running the lifting device. In traveling, permanent magnets attached to the entire outer periphery of the endless track driven by the drive motor are sequentially attracted and driven by guide rails made of a magnetic material such as an iron plate. The control unit is responsible for controls such as an inclination adjustment unit, a drive unit, and operation control. The electric power required for the operation of the lifting device is supplied by an external power supply or a battery. FIG. 4 shows an embodiment for ensuring linearity when the lifting device travels.
Attach the grooved guide ring (21) to the end of the drive shaft,
An example is shown in which the guide rail end is bent and the guide ring (21) runs while sandwiching the bent portion. The guide for the rail may be provided not only at the end of the rail but also at the center of the rail. FIG. 5 shows an embodiment in which a non-slip is provided on a rail surface as a non-slip when the elevating device moves up and down a steep slope. Since the permanent magnet block on the outer circumference of the endless track that drives the lifting device engages with the non-slip arranged in the step shape, the vehicle travels reliably without slipping on the inclined surface. The non-slip method is not limited to this method, and a method may be used in which holes are provided at equal intervals in the guide rail, and the outer periphery of the endless track runs while meshing with the holes. FIG. 7 shows an example of a method in which the elevating device changes the direction. A turntable (11) is provided at the corner of the building, and when the lifting / lowering device comes to the corner, it is moved onto the turntable (11), and then the rotary table is rotated with the lifting / lowering device mounted thereon, so that The direction of travel can be determined. In this manner, the rotation angle can be selected even if the angle of the corner is an arbitrary value.
