Sliding door handle system with latch for unlocking
A newly granted patent (Publication Number: US11959302B2) discloses a handle system designed for sliding door systems. The system includes a first panel and a second panel, with one panel moving parallel to the other and both panels capable of pivoting together. A handle on one panel is connected to a latch that, when moved away from the panel, transitions the latch from a locking to an unlocking position, enabling the panels to pivot. The handle pivots around a pivot pin and features a slot for a slide pin, facilitating smooth movement when the handle is operated. An actuating portion on the handle is responsible for moving a rod axially to control the latch's position, with a spring biasing the latch and handle to their default positions.
Furthermore, the patent details a method for configuring sliding door panels to pivot effectively. By providing a handle on one of the panels and designing it to operate a latch, the system allows for vertical movement of the latch between locking and unlocking positions, enabling multi-panel pivoting. The method involves utilizing a spring to compress during handle operation and a slide pin mechanism for seamless movement. Additionally, a camming portion on the handle interacts with a projection connected to the latch to facilitate smooth latch movement during handle operation, ensuring efficient and reliable functionality of the sliding door system.
