Abstract

A hand grip for use in controlling machinery. The grip includes a grip body and a hand rest connected to the grip body. The hand rest adjustably slides and rotates with respect the grip body grip. The hand rest includes a first locking part that is configured to engage the grip body to lock the hand rest in a locked position with respect to the grip body such that the hand rest does not slide with respect to the grip body and configured to disengage from the grip body such that the hand rest slidably moves with respect to the grip body. The hand rest includes a second locking part that, when unlocked, allows the hand rest to rotate with respect to the grip body, and that, when locked, prevents the hand rest from rotating with respect to the grip body.
