Anti-toppling chair

Abstract

The invention discloses an anti-toppling chair, which comprises a seat plate, front legs, transverse connecting rods, rear legs and an anti-toppling mechanism, wherein two front legs are arranged, and one end of each front leg is rotationally connected with the seat plate; two rear legs are arranged, and one end of each rear leg is rotationally connected with the seat plate; the transverse connecting rods are rotationally connected with the middle of the front legs and the rear legs; the seat plate, the front legs, the transverse connecting rods and the rear legs form a rotatable chair; and the anti-toppling mechanism is provided with a supporting assembly located on the rear side of the rear leg and a detection assembly located in the front leg. When the chair is tilted, a telescopic rod in the front leg can extend along with the backward inclination angle, so that a front leg lock catch is separated from an arc-shaped groove, the whole chair is deformed into a parallelogram, meanwhile, the telescopic rod extends to drive a transmission steel wire to pull the lock catch, a lower swing elastic belt drives a rear swing rod to rotate downwards along a ratchet wheel seat, an auxiliary supporting effect is played, and the whole seat is in a parallelogram shape to form a stable structure, so that the situation that a person falls down due to the fact that the gravity center is out of control when the person tilts the seat is prevented.

Description

technical field [0001] The invention relates to a chair, more precisely, an anti-tipping chair. Background technique [0002] In real life, a chair is a tool for us to sit down and rest, but because a large number of people develop bad habits when sitting on a chair, they like to tilt the chair when sitting on the chair, but once the chair is tilted backward, the center of gravity of the person is out of control, There is a high probability that it will cause a fall, and even cause the back of the head to land, causing major injury, and even death. Contents of the invention [0003] In view of the above problems, the present invention provides an anti-dumping chair. When the chair is tilted, the telescopic rod inside the front leg will elongate with the angle of inclination backward, so that the front leg lock will break away from the arc groove and the entire seat will be deformed. It is a parallelogram. At the same time, with the extension of the telescopic rod, the tra...
