US Patent 7886632 Handle grip

A handle (10) for controlling a machine, has a largely vertical shaft (12) forming a grip part (11) and has an upper end forming a receptacle (14) that holds switch units (15-17) and a lower end forming a hand rest (20). The hand rest can be adjusted along the shaft (12) and can be detachably clamped to the shaft. The hand rest (20) comprises front and rear rest part (26, 27) that are pivotally, or swivelably, connected to one another. To prevent unintentional opening of the hand rest (20) by axial pressure on the latter, the two rest parts (26, 27) can be moved relative to one another in the axial direction to effect a locking and unlocking of their relative pivotabilities.
