Zipper type upper cross beam lifting device of door frame type walking aid

Abstract

The invention relates to a lifting device of a walking aid, in particular to a zipper type upper cross beam lifting device of a door frame type walking aid. The purpose of the invention is realized in the way that: the zipper type upper cross beam lifting device comprises an annular long zipper, a slow-down self-locking mechanism, a winch, upper cross lintel shafts, supports and the like. A left support and a right support of the lifting device are provided with a rotary upper cross lintel shaft respectively; the shaft body of the other end of the upper cross lintel shaft is also inserted into holes at the left end and the right end of the winch; when the length of the part of an adjusting shaft extended into the winch is adjusted, the width of the zipper type upper cross beam lifting device can be changed; a gear is also fixed on the upper cross lintel shaft at one end and is also engaged with an output gear of the slow-down self-locking mechanism on the support at the same end; an input shaft end of the slow-down self-locking mechanism is provided with a chain wheel; the annular long zipper is sleeved on the chain wheel; and the combined zipper type upper cross beam lifting device becomes a relatively independent component and can be inserted into stand columns on the two sides of the walking aid.

Description

Technical field: [0001] The invention relates to a lifting device for a walker, in particular to a zipper type upper beam lifting device for a door frame type walker. Background technique: [0002] The hoisting device of the door frame type walker seen now is just that after the rope goes around the upper cross beam of the door frame type walker, one end of the rope is wound on the winch device installed in the middle of the walker column, and the winch device is rotated to wind the rope , so that the other end of the rope moves up and down, and the moving rope passes through the safety belt tied to the user at this end of the rope to pull the user up or down, so as to help the user stand and walk safely. Although the lifting device of this kind of door frame type walking aid is simple, because the rope it lifts is to go around the upper beam and then connect to the two winch devices installed in the middle of the two columns, this makes the lifting device different from the...

Problems solved by technology

Although the lifting device of this kind of door frame type walking aid is simple, because the rope it lifts is to go around the upper beam and then connect to the two winch devices installed in the middle of the two columns, this makes the lifting device different from the walking aid. The other parts of the walker should be integrated into a whole system. When it needs to be disassembled, especially when the height of the users is different from fat or thin, it becomes very difficult to adjust the height of the column of the door frame walker in time, especially when the width needs to be adjusted. Moreover, the winch device also occupies a certain use width, which makes the walker very wide, and it is inconvenient to use both hands at the same time.
