  • Patent number: 6332586
    Abstract: A winding device for fire hoses (40, 42), loading straps, etc., comprises a freely rotatably mounted, sleeve-shaped coil (12) having a longitudinal cavity (36) which, circumferentially, is defined between two clamp faces (14a, 14b). Within the cavity (36) is disposed a clamp means (34) firmly connected to a crank device (26′, 26, 24, 32) and pivotal from a first position, resting against a first clamp face (14a), to a second position, resting against a second clamp face (14b). The clamp means (34) is a straight, rod-shaped element connected to the crank shaft (24) through a lateral crank arm (32) outside the inner cavity (12′) of the coil (12). A starting portion of a fire hose, e.g. a loop-shaped portion (42) at the center of a double-laid fire hose (40), can be placed around such a clamp means (34), whereupon the hose is wound up.

  • Patent number: 6068210
    Abstract: A spooling device for load straps comprising a spool, which at one end portion is freely rotatably supported and is formed as a projection and has a centrally passing axial bore for receiving an axle, at the end opposite the free outer end of the spool, the axle is drivingly connected to a manual crank, the spool formed with a V-shaped notch tapering radially towards the bore, and the axle provided with a radially directed, strip-shaped clamping jaw, whose free edge extends parallel to the axis of rotation of the axle/spool and forms the carrier of the axle, for affecting and rotating the spool, the surface of the clamping jaw of the axle, facing the direction of the rotation, and the opposite clamping jaw surface defining the spool notch, form a co-operating clamping surface pair by which the strap end is clamped and kept clamped during the entire spooling operating as long as the cranking is kept up.
