Document Type and Number:
WIPO Patent Application WO/2023/122941
Kind Code:
A1
Abstract:
A push-down and pull-up door handle having an easily-replaceable lever handle. A second lever handle (8) is disposed on a side of a first lever handle (7), and an eccentric square strip (6) is mounted between the first lever handle (7) and the second lever handle (8). A rosette (5) is mounted at an end of the first lever handle (7), a base (1) is mounted in the rosette (5), a rotary block (2) is mounted in the base (1), and bidirectional torsion spring (4) is mounted in the rotary block (2) by means of engagement and pressing. A set screw (9) is mounted at a bottom end of each of the first lever handle (7) and the second lever handle (8), a hexagonal recess (19) is provided at a bottom end of a set screw (9), and a position-limiting post (17) is mounted at a top end of a set screw (9). Eccentric holes (18) are provided at two ends of the eccentric square strip (6), and the position-limiting post (17) can extend into the eccentric square strip (6), so as to reliably mount and fix the first lever handle (7) and the second lever handle (8). Interaction between the base (1), the bidirectional torsion spring (4), and the rotary block (2) enables the door handle to rotate not only upwards but also downwards when in use. In addition, in use, the door handle can be easily removed and replaced by unscrewing the set screws (9) and pulling same outwards.
