Description

Technical Field

[0001] The present application relates to the field of seats, and in particular to a lifting footrest. Background Art

[0002] Because traditional desks are designed for adults, they are relatively high, so children often need to use adult chairs or raise the chairs, so it is difficult for their feet to touch the ground. To make it easier for children to use, some learning chairs have footrests on the legs of the seats, which are convenient for children to step on; however, most existing learning chairs cannot adjust the height of the footrests and cannot adapt to children of different school ages and heights; as children grow older and taller, the footrests become just for show and are not very practical.

[0003] The utility model patent CN201620460166.6 provides "a chair leg with an adjustable height footrest and a study chair using the chair leg", the chair leg comprises a chair leg body and a plurality of legs; the legs are arranged divergently around the chair leg body; a footrest is provided on each of the two connected legs for the user to rest his feet; each footrest comprises a pedal, a connecting rod, at least one pad and a handwheel; the pedal is located above the leg and connected to the connecting rod; the pad is passed through the connecting rod; the connecting rod passes through the leg from top to bottom; the handwheel is located below the leg and connected to the connecting rod. The study chair with a chair leg with an adjustable height footrest can adjust the height of the footrest simply and conveniently, which can meet the needs of children of different school ages and heights to study and use in a traditional non-lifting traditional desk environment, protecting the health of the children. Although the study chair can adjust the height of the footrest, the adjustment steps are cumbersome, and the footrests on the two legs need to be disassembled in turn, and then the pads need to be added or reduced, and then the footrests need to be locked in turn; the operation is undoubtedly very troublesome and inconvenient, and the sense of technology is not strong.
