Abstract: A carriage is described, in particular for transporting medical devices in hospitals, comprising a carrier (2) for bearing a load to be transported, at least three, preferably four casters (5) arranged in a roller plane having caster swivels (6), on which the carrier (2) rests, at least two of the caster swivels (6) being adapted for pivoting around a geometric rotational axis (7) which runs perpendicular to the roller plane, and a fixing mechanism (15), by which the carriage (1) can be secured against rolling away. According to the present invention, the fixing mechanism (15) has locking devices (17) coupled to an actuating element (16), by which the at least two of the rotatable caster swivels (6) are lockable, by actuating the actuating element (16), in different rotational angle positions in such a manner that the casters (5) fastened thereto are oriented differently.

Abstract: The present invention relates to a retroaction-protected transmission module for a motor for driving a retroaction-endangered load, in particular of a gate, having a transmission (11) having a drive side and an output side and a blocking clutch (1) having a clutch state and a blocking state, the blocking clutch including a driveshaft (12), which has driver parts (2) on one end, between which clamping bodies (3) are movably located, which surround a head (4) of an output shaft (13), the head (4) of the output shaft (13) having coupling faces (5), which are in contact with the clamping bodies (3) in the clutch state and via which, in the clutch state, the clamping bodies (3) carried by the driver parts (2) in the event of a rotation of the driveshaft (12) transmit a torque from the driveshaft (12) to the output shaft (13), and a braking ring (6) having a clamping face (7) being located around the clamping body (3), against which the clamping bodies (3) are pressed by the coupling faces (5) in the blocking state

Abstract: A transmission adapted for use with a motor comprises a basic transmission, which comprises a basic transmission input shaft, borne in a housing via rolling bearings, at least one subsequent transmission stage arranged in the housing, and a variance gear designed for meshing with a drive pinion of the motor and pressed onto the basic transmission input shaft from the input side of the transmission. A support is arranged in the housing, in fixed position relative to the housing, in such a manner that the basic transmission input shaft contacts the support, under the effect of the pressure force necessary for pressing the variance gear onto the basic transmission input shaft, so that the support essentially bears the pressure force and distributes it over the housing.
