Description

Seat and arm rest drives of the lift system

The present invention is a wheelchair for a disabled person, an elderly person, a patient, a pregnant woman, or a lift system for carrying a relatively heavy load, and a seat for the passenger to sit and a arm rest for the passenger to hang the arm ( More specifically, the present invention relates to a device for interlocking an arm rest, and more particularly, a seat and arm of a lift system that doubles the convenience of use by allowing the seat and arm rest to automatically fold simultaneously by folding the boarding base of the lift car. It relates to a rest drive device.

Conventionally, various types of lift systems for transporting wheelchairs or relatively heavy cargoes for the handicapped, the elderly, the sick, the pregnant, and the like are known. The typical embodiments of the present invention will be described below with reference to the accompanying drawings. .

As shown in FIG. 1, posts 2 are erected at corners of each staircase 1, and upper and lower guide rails 3 and 4 are fixed to the posts 2. A cable (not shown) is inserted into the lower guide rails 3 and 4, and the cable is connected to the driving device 5, and the lift car 6 is installed at a predetermined portion of the cable. Is connected.

According to the conventional lift system as described above, when the lift car 6 operates a separate driving button in a state where a disabled person, an elderly person, a patient, a pregnant woman, or a wheelchair, or a relatively heavy load is mounted, As the cable is moved by the driving device 5, the lift car 6 is raised or lowered with the guidance of the upper and lower guide rails 3 and 4.

On the other hand, the lift car 6 according to the prior art as shown in Figure 2, the lift body 11 is connected to the cable and moved along the upper and lower guide rails (3) (4), and A seat 12 rotatably installed at an intermediate portion of the lift body 11 and a passenger seated on the seat 12 are rotatably installed at both upper sides of the lift body 11 to support an arm. Arm rests (also referred to as 'foldable armrests') 13 and a boarding base 14 that are rotatably coupled to the lower portion of the lift body 11 and rotated on both sides of the boarding base 14, respectively. It includes a safety landing board 15 that is coupled to be possible.

Therefore, when a disabled person, an elderly person, a patient, a pregnant woman, or the like does not mount a wheelchair, the seat 12 is laid in a horizontal state, and the arm rest 13 is laid in a horizontal state.

However, according to the conventional lift system as described above, when the lift car 6 is not used, the seat 12 and the arm rest 13 have to be manually stored. This is not an easy task for people with disabilities, elderly people, patients, pregnant women, such as the disabled, in some cases there is a problem that can not rule out the occurrence of a safety accident.

Accordingly, an object of the present invention is to provide a seat and arm rest driving device of the lift system to double the convenience of use by automatically folding the seat and the arm rest at the same time by the folding base of the lift car.
