摘要:
A guiding device for an elevator door leaf that includes a body within which at least a first cavity open outwards of said body. The guiding device also includes a first spherical element rotatably inserted in the first cavity and arranged so as to protrude from the first cavity outwards and anti-friction means interposed between the first spherical element and at least one wall delimiting the first cavity to limit the movement of the first spherical element within the first cavity.

A device for preventing excess speed, which is caused by an energy store, of a door leaf, includes a door leaf displaceable between an open position and a closed position, an energy store coupled with the door leaf, which energy store provides energy for the closing movement of the door leaf in the event of failure of the electrical energy supply, a door drive coupled with the door leaf, wherein electrical energy can be induced in the door drive when closing movement of the door leaf takes place, and a door control, which activates the door drive and which is suitable for regulation of the speed of movement of the door leaf, wherein the door control is operable by the induced electrical energy when the electrical energy supply fails, and a method of operating an elevator door.
摘要:
Door arrangement, more particularly a sliding door arrangement of an automatic door of an elevator or of a building, which comprises a door panel, and a guide arrangement for controlling the path of movement of the door panel, which guide arrangement comprises at least one guide connected to the aforementioned door panel, and a guide rail, closely along which the aforementioned guide is arranged to move, and from which guide rail the guide takes lateral support force with respect to the longitudinal direction of the guide rail. The guide comprises a first guide roll for taking the support force from the guide surface of the guide rail on the side of a first side of the guide, and a second guide roll for taking support force from the guide surface of the guide rail on the side of a second side of the guide.
摘要:
The position of a moveable component which is coupled to an electric machine is ascertained, where the electric machine serves, in the event of manual movement of the component, as a generator for generating electric energy for a position ascertainment arrangement. The coupling of the electric machine with the component is configured such that a magnetic attraction reaction and/or repelling reaction between magnetic and/or magnetized parts of a rotor and of a stator of the electric machine results in a short-term acceleration of the rotor, which is unhindered by the coupling, and in a resulting short-term increase of the electric energy generated.

An elevator door system includes an elevator car having a front face defining a door opening. At least one elevator door is coupled to the front face of the elevator car for movement between an open position exposing the door opening and a closed position covering the door opening. At least one drive motor is mounted on the front face of the elevator car and is disposed between a lower edge and an upper edge of the elevator car. The drive motor is drivingly coupled to the elevator door for moving the elevator door between the open and the closed positions.

摘要:
An assembly (20) for controlling movement of an automatically moveable door panel (22) includes sensors (30, 50) such as microswitches positioned on at least one of a door panel (22) or a door frame member (26). The sensors provide an indication of different levels of relative movement between the door panel and the door frame member at an interface (28) between them. Such relative movement includes an increase in a gap between them that corresponds to a situation when an object is at the interface (28) and may be caught. The sensors (30, 50) respectively provide an indication of when an object may become caught and when one has. Automated movement of a door is controlled responsive to an indication of the presence of an object in a location where the object may become caught during automatic movement of the door.

摘要:
A safety device for lift doors and sliding doors or shutters in general, electrically powered, specially suited to avoid the danger of having one's fingers being caught in between the lift doors (12-14) and the respective jambs (10) or between the two doors while the latter are opening, of telescopic or central opening type, with glass or crystal (16) with a frame (18) or of a different type, includes at least one electrosensitive strip (20) with middle edge (26) orthogonally developed from the base, vertically extended on at least one of the jambs (10) and/or doors (12) and/or (14) and electrically wired to the cage door control board or to the lift system control board or indirectly connected to e.g. an infrared transmission system.
摘要:
A method and apparatus for facilitating closure of an elevator hoistway door generally comprises the steps of affixing a door closer device to the hoistway door and securing a cable, extended from the door closer device, to a terminal off the hoistway door. The door closer device comprises a sheave repeatedly circumscribed by an elongate channel for receiving the cable therein and a spring adapted to oppose extension of the cable from said door closer device. The channel, which generally prevents overlap of the cable during retraction into the door closer device, preferably forms a conical helix during the final retraction of the cable, thereby increasing the force exerted upon the door by the cable as the door approaches the door closed position.
