Abstract:
A device for manually maneuvering a handling unit, comprising:a mounting structure configured for attachment to a handling unit; a control mechanism connected to the mounting structure and including keys, actuated from outside, for activating a movement of the handling unit; and a handle frame connectable to the mounting structure and configured to allow an operator to actuate at least one of the keys with a thumb, wherein the handle frame includes a cross member having opposite axial ends, a pair of elongate grip elements, one of the grip elements extending transversely to the cross member and having one end detachably connected to one of the axial ends, and the other of the grip elements extending transversely to the cross member and having one end detachably connected to other one of the axial ends, and fastening means for releasably attaching the cross member to the mounting structure, wherein the cross member and the grip elements are selected from a plurality of cross members and grip elements of varying lengths to thereby establish a construction kit to allow construction of the handle frame with a desired configuration, wherein the fastening means includes a fastener configured to allow displacement of the cross member in axial direction and thereby effect a positional adjustment of the grip elements with respect to the keys, before securely fixing the cross member to the mounting structure.
