Abstract
The present disclosure provides an armrest device (2) for an operator chair (1), comprising an armrest plate (2a), an upper arm (6a, 6b), a lower arm (5a, 5b), and a clamp (12) for attachment to a support structure. The device includes multiple joints (3, 3a, 4, 13, 14, 15, 16) connecting components, at least one gas cylinder (7, 8) for enabling or disabling movements, and a lock/release system (21) to control the gas cylinder's mode. A first control mechanism (9) on the armrest plate (2a) allows user operation without hand removal, controlling the lock/release system (21) to set the gas cylinders (7, 8) in released or locked mode.
Claims9
An armrest device for an operator chair, which armrest device comprises:
- an armrest plate;
- an upper arm;
- a lower arm;
- a clamp for attaching the armrest device to a support structure of the operator chair;
- a plurality of joints joining the armrest plate, the upper arm, the lower arm, and the clamp with each other;
- a first gas cylinder configured to enable movements of the inclination of the lower arm when set in a released mode, and to disable said movements when set in a locked mode;
- and
- a second gas cylinder configured to enable movements of the inclination of the upper arm when set in the released mode, and to disable said movements when set in a locked mode;
- a lock/release system configured to simultaneously set the first gas cylinder and the second gas cylinder in either released mode, or locked mode;
- a first control mechanism connected to the lock/release system, wherein the first control mechanism is located at the armrest plate for user operation without removing a hand of the user from the armrest plate;
- and wherein the first control mechanism is configured to via the lock/release system simultaneously set the first gas cylinder and the second gas cylinder in either released mode, or locked mode.
