  • Patent number: 9827843
    Abstract: A wheel of a roller includes a roller axis, the wheel being driven by an electric motor, wherein the electric motor is a hub motor which drives a hub body, which extends with circumferential spacing and surrounds the wheel axle, relative to the fixed wheel axle, wherein furthermore the wheel has a running surface. The running surface is formed on a running surface carrier and the running surface carrier is supported flush on the hub body at the back of the running surface. Further, a manually movable load truck includes one or more rollers, of which at least one roller has a driven wheel. Further, an operating device, in particular for a manually movable load truck, is formed having a substantially annular cross-section having a central through opening.

  • Patent number: 9481206
    Abstract: The invention relates to a roller (1) having a wheel (2), which is accommodated in a housing, and a locking device (10, 17), the locking device (10, 17) being actuated by foot actuation of an actuating element (5) which is arranged so that it extends radially outwardly with respect to a vertical (V) that passes through a securing portion of the roller (1). To provide a roller which is advantageously formed with regard to locking by foot operation, it is proposed that an actuating portion of the actuating element (5) extends circumferentially at least far enough that a second foot actuation in the circumferential direction with respect to the vertical (V) may be carried out next to an area of the actuating portion by way of which a first foot actuation has been carried out.

  • Patent number: 8978795
    Abstract: An additional roller has a rigid frame, with a drivable wheel which is mounted in the frame and has an axle. The wheel together with the frame can be raised or lowered by pivoting relative to a chassis, on which the additional roller is to be mounted. A compression spring is coupled rotatably at one end to the chassis, in order, in the lowered position, to load the wheel in respect of ground contact. A transverse connection connects two frame parts in the direction of an axle of the wheel. The compression spring is coupled at the other end to the transverse connection. The compression spring together with the frame pivots about the chassis-mounted pivot point during raising and lowering of the wheel.

  • Patent number: 8051533
    Abstract: The invention relates to a double roller (1) with two running wheels (2) and one carrier housing (3), wherein an assembly journal (6) is arranged on the carrier housing (3). An actuating tappet (15) can be displaced in the assembly journal against a spring force, interacting with a counter locking part (65) for directional and/or complete fixation. Furthermore, a running wheel braking part (25) with engaging parts (37, 38) is provided for blocking the rotation of the running wheels (2). The running wheel braking part (25) is likewise actuated by the actuating tappet (15) and furthermore the housing section (4) accommodating the actuating tappet (15) includes a ball bearing (8) on the upper side and surrounds the actuating tappet (15) at least partially toward the bottom. In order to enhance a double roller of this type, it is proposed to have the counter locking part (65) inserted underneath the ball bearing (9) in the part of the housing section (4) that opens only in regard to the inner opening.
