  • Patent number: 4655323
    Abstract: An elevator, especially an oblique elevator, has a plurality of telescopic sections, along which a load container is movable. The telescoping of the sections takes place in such a manner that all the telescopic sections move simultaneously in relation to one another, or in such a manner that, as a given telescopic section extends, it takes with it all those arranged after it, as a "pack". For the purpose of locking in any desired position of extension a locking/unlocking device is provided between each pair of adjacent telescopic sections. This locking is effected by the actuation of a draw cable attached to the lowermost telescopic section, the draw cable acting upon an actuating cable which effects the locking or unlocking. The actuating cable runs in tackle block manner around two cable guides, and is shortened or lengthened by the variation of spacing of two cable guides.

  • Patent number: 4640387
    Abstract: The invention relates to a locking device between two relatively movable telescopic sections of an elevator such as a scaffolding or load hoist. The individual telescopic sections are locked together by a locking dog. The locking system can be arranged to snap in automatically, and to be released by cable actuation, or vice versa. The locking dog is actuated by a draw cable which controls a locking/release cable. The cable stretch of the draw cable is compensated by a tackle block reversal thereof, that is to say a substantially greater shortening takes place (with reduced force application) in the draw cable compared with the locking/release cable. Thus, a mechanical advantage is obtained not only within the draw cable itself, but also between the draw cable and the locking/release cable.

  • Patent number: 4550806
    Abstract: An elevating apparatus comprises an inclined elevator and a load-carrying carriage. The inclined elevator comprises a pair of guide rails, and the carriage is movable along the guide rails by means of a cable. The carriage is movable along the guide rails on rollers provided on rocker arms pivotally mounted on the carriage. The upper portion of each guide rail is angled away from the remaining portion of that guide rail, the upper portions of the guide rails defining a horizontal section of the elevator which constitutes a discharge position for the carriage.

  • Patent number: 4546854
    Abstract: The invention relates to a load-carrying platform, particularly for moving furniture or the like along an inclined elevator. The load-carrying platform is supported by a carriage which is movable along guide rails of the elevator. Telescopic guides are provided between the carriage and the base of the platform, so that the platform is displaceable in relation to the carriage. Thus, when the unloading position is reached, the platform can be moved, at least partially, through a window opening and into the interior of a house.

  • Patent number: 4498263
    Abstract: A telescopic beam comprises a plurality of telescopically-interconnected members which define rails along which a load-carrying tub can move. Means are provided for locking the telescopic members together. The beam is provided with a pair of tensioning cables which bridge several of the telescopic members. The cables are guided by means of spacers attached to the telescopic members.

  • Patent number: 4491196
    Abstract: A telescopic beam for use in an inclined hoist has five telescopic members. An actuator comprising a motorized winch and a block and tackle arrangement is provided for extending the telescopic members relative to one another. The block and tackle arrangement includes a cable which passes several times around sets of rollers positioned at the adjacent ends of first and second of the telescopic members. A lock is provided for fixing the positions of the first and second telescopic members. To relieve the operator of the need for controlling several actuators, the single actuator is used to control the extension of all the telescopic members, and to control the angle of inclination of the last telescopic member relative to the penultimate telescopic member. For this purpose, the cable is passed from the second telescopic member to the far end of the penultimate telescopic member, and then to the adjacent end of the last telescopic member where it is secured.
