Description

Staircase auxiliary lifting assembly structure

The invention discloses a lifting platform mechanism, in particular to convert a platform state into a platform state, and the platform carries the auxiliary equipment up and down the stairs, and the mechanism can be modularized to increase the installation convenience, and the narrow stair space is effectively utilized. Especially for home care.

In general building-type dwellings, stairs are the biggest obstacle to space movement for those who rely on auxiliary vehicles, especially for the elderly, the disabled, the injured and other types of accessories. In order to move between the upper and lower floors, it is usually necessary. The special person first carries and transports to the designated floor and then carries the auxiliary equipment, which is quite inconvenient for moving between floors. At present, it is common to provide upper and lower floor facilities such as “elevator”. In addition to the planned installation space of the building at the design stage, the general building type house cannot provide sufficient space for installation, and the elevator installation must be changed in addition to the structure of the building. The cost of installation and subsequent maintenance can be affordable to the general public.

At present, the various mobile auxiliary devices of the upper and lower floors have the functions of assisting the user to go up and down the floor, but the speciality is extremely high and the equipment is expensive, and it is not widely available. Among them, stair-type auxiliary equipment can also be used as a slab step in normal times, and it has less influence on the walking space after the setting, and is more suitable for promotion. At present, the Republic of China patent M372709 discloses a lifting platform structure, but the lifting platform structure disclosed therein requires a large space. The power unit is configured, and the higher the lift height, the more space is required, so it is only suitable for low-rise steps on the required space and safety considerations. In addition, the structure of the lifting platform disclosed in the Republic of China patent M372709 cannot be installed in the existing stair structure, that is, the user must destroy the stairs in the home to install the lifting platform structure, so the feasibility of using at home is not high.

Furthermore, for building space restrictions, it is not possible to plan elevators, handicapped ramps, or to install stair lifts, the stairway is narrow and prone to collision hazard, and for users who cannot walk independently, U.S. Patent Nos. 7,225,899 and 7,708,117 disclose The use of the exclusive power stair lift chair gently rises along the track, but for the use of the stair lift chair still needs to be handled by a person, and is easy to cause accidents during the handling process, by the invention to create a ladder plate conversion method and device, the ladder plate conversion It is a platform for carrying auxiliary equipment, which can directly carry auxiliary equipment and users up and down to designated floors.

As described above, the creator of the present invention contemplates and designs a stair-assisted lifting assembly structure, and after years of painstaking research, it is improved by the lack of the prior art, thereby enhancing the implementation and utilization of the industry.
