Title:
FURNITURE LEGS ADAPTIVE TO GROUND ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2022/257126
Kind Code:
A1
Abstract:
Furniture legs adaptive to a ground environment, relating to the technical field of furniture. Vertical sleeves (16) or engagement sleeves (26) and sliding grooves (25) or guide rails (23) and guide sleeves (24) of a vertical retainer are employed to enable the legs to be always vertically perpendicular to a horizontal plane on an inclined ground and an uneven ground. A telescopic sleeve joint (15) of the vertical retainer is used for adapting to a change in the distance between height adjustable telescopic cylinders (3) when the angle between each movable rotating assembly (2) and each movable rotating connecting rod (12) is changed. The telescopic length of each height adjustable telescopic cylinder is adjusted by exerting forces on the use surface of furniture by lying or sitting thereon or pressing same with hands, so that the lower ends of the legs can be in contact with an inclined ground and an uneven ground, and the furniture can be stably placed and adjusted to an inclination angle and a use posture position of the use surface matched with a use posture in which a user feels the most comfortable. The length of each height adjustable telescopic cylinder (3) is locked to be unchanged by means of an interception multi-way valve (7) or interception valves (20) after the furniture is located at the most comfortable position of the user.
