摘要:
An overhead door apparatus (10) utilizing a torsion spring counterbalancing mechanism (30). The counterbalancing mechanism (30) includes a worm drive ring-shaped gear winding mechanism (38) for setting the appropriate torque or number of winds in the spring (32). A counting mechanism (140) is provided to indicate to the installer the number of winds being given to the spring (32). Means are also provided for accommodating spring growth and contraction during winding and unwinding using the winding mechanism (38) and during normal raising and lowering of the door (12). A spring clip gear retainer (82) is disclosed for preventing rotation or creep of the worm drive gear (70) and spur gear (56) during normal raising and lowering of the door (12). A second embodiment is disclosed allowing more universal interchangeability of components between the left and right sides of the door system (200), easy snap-in assembly, and including a telescoping spring cover (252). Each embodiment includes a spring winding counter (140).

A hydraulic operating device for gate movement comprises a gate pintleing unit (10) comprising a box (11) with rotating support body (37) for a shaft (12) having a first gear (20) integral therewith projecting into the box. The shaft (12) faces at the top a box (11) with one of its axial fixing ends (15) integral with the gate rotation axis. The device also comprises a hydraulic operating unit made up of a drive element (25) consisting of a central body (32) from which project opposed hydraulic cylinders (26,27) in which run respective pistons (28,29). Between the pistons is connected a rack (30) traversing the central body (32) to project laterally therefrom with its teeth. It is thus possible to prepare a gate for future automation by mounting only the box and subsequently inserting therein the operating unit.
摘要:
Beschrieben wird ein Haltegriff mit einem U-förmigen Griffkörper (1), der mittels Lagerachsen (6) in Lagerböckchen (5) schwenkbar gelagert ist. Durch eine Rückstellfeder (7) ist der Griffkörper (1) nach Gebrauch in eine Nichtgebrauchslage überführbar. Damit es bei der Rückstellbewegung nicht zu harten Anschlaggeräuschen kommt ist eine Reibungsbremse vorgesehen, die aus einem Formkörper (8) aus verschleißfestem, zähelastischen Kunststoffmaterial besteht, welcher eine Bohrung (9) zur Aufnahme eines axialen Bereichs einer der Lagerachsen (6) aufweist, die enger als der Durchmesser der Lagerachse (6) ausgeführt ist, jedoch eine Relativbewegung zwischen Formkörper (8) und Lagerachse (6) zuläßt.

摘要:
A door open position fixing device (8) including a presser member (16) adapted to abut against a vehicle door openable up to a predetermined angle defined for every vehicle of different kinds, and a driving mechanism (18) for swingably driving the presser member (16) to make the same press the door in an opening direction thereof and maintain an open condition of the door. The door open position fixing device (8) is provided with a detecting device for detecting a swing degree of the presser member (16) and a control device for controlling the driving mechanism so that the swing degree of the presser member (16) detected by the detecting device becomes equal to a predetermined value preliminarily set for the door of the every vehicle of different kinds.
