When used as a crutch, the upper joint, the middle joint and the lower joint are respectively locked into straight rods by locking devices, and the handle is installed on the top of the upper joint. When used as a stool, the left and right curved rods of the upper joint and the lower joint can rotate around the pin to form a certain angle, which is used as the supporting part of the stool; the left and right semicircular rods of the middle joint follow the left and right curved rods of the upper joint and the lower joint The parts are unfolded and separated in parallel, and at the same time are fixed by the locking device, causing the cloth strips located inside the middle joint to be fully tensioned and serve as the sitting surface of the stool. The invention is simple in structure, reasonable in design, novel and unique, can be used as a crutch when walking, and can be used as a stool after simple deformation when resting. At the same time, the electronic equipment integrated in the handle can also facilitate the daily life of the elderly.

Description

New multifunctional crutches

technical field

The invention discloses a novel multifunctional crutch which integrates stool and entertainment functions, and relates to the technical field of daily necessities for the elderly.

Background technique

At present, most of the crutches on the market have a single function. Many elderly people need to prepare corresponding daily necessities before going out, such as stools, electronic entertainment equipment and compass, if they want to take a temporary rest, listen to entertainment programs at any time, and determine their real-time position when they use crutches to assist them in walking. Therefore existing crutch has increased its additional burden for the elderly with poor memory and inconvenient carrying, and has influenced the use of the elderly in terms of convenience.

Contents of the invention

In order to solve the inconvenience caused by the single function of the existing crutches, the present invention provides a new type of multifunctional crutches, whose overall shape is no different from that of ordinary crutches. When the elderly need to walk, they can be used as ordinary crutches; When resting, it can be transformed into a stool for resting by simple folding. In addition, the electronic products integrated on the handle of the crutches also provide convenience for leisure and entertainment for the elderly.

The technical solution adopted by the present invention to solve the technical problem is: the present invention relates to a multifunctional crutch, including a handle, an upper joint (the first joint of the crutch body), a middle joint (the second joint of the crutch body) and a lower joint ( The third joint of the cane body). Its characteristics are: the upper joint and the lower joint are composed of left and right curved rods with semicircular cross-section; the middle joint is composed of left and right semicircular rods with hollow inside, and cloth strips, handwheels, bearings and rotating shafts are installed inside. When the present invention is used as a crutch, turn the hand wheel fixed on the rotating shaft, put away the cloth strips in the middle joint, fix the upper joint, the middle joint and the lower joint as straight rods respectively through locking devices, and put the handle It can be installed on the top of the upper joint. When the present invention is used as a stool, the left and right curved rods of the upper joint and the lower joint can be rotated around the pins to form a certain angle as the supporting part of the stool; The curved rods are unfolded and separated in parallel, and at the same time are fixed by the locking device, causing the cloth strips located inside the middle joint to be fully tensioned, serving as the seating surface of the stool. In addition, lighting, radio, GPS positioning system, MP3 player and compass are integrated in the crutch handle, which can meet the life and entertainment needs of the elderly when traveling.

The beneficial effect of the invention is that the crutch can be easily folded and deformed into a stool for the elderly to rest, and the electronic equipment integrated in the handle of the crutch also improves the practicability of the crutch.
