Abstract:
This invention relates to an operating unit for one or more gate, window, door or roller shutter drives. In accordance with the invention, one basic element is provided for each driven gate, window, door or roller shutter. The basic elements each accommodate the operating elements required for operating a gate, window, door or roller shutter drive, and can be joined together.
Abstract:
A device (1) for use with a cable-operated door (3), such as garage doors (3) and the like, and a door assembly including the same. The device (1) is intended to reduce the risk of the door (3) falling, or at the very least slow down its descent, in the event of a failure in the counterbalancing mechanism of the door (3), which is generally represented by a loss of tension in a given tensioned cable (5) operating the door (3). The brake device (1) includes a support bracket (9), and a guiding assembly 15 and a braking assembly 17 mounted onto the support bracket (9). The braking assembly includes a swivel component (18) having opposite braking arm (19) and lever portion (20), the lever portion cooperating with the tensioned cable (3) so that in the event of a loss of tension in the cable (5), the braking arm (19) is urged onto an adjacent rail (7) via biasing means (21) for anchoring a knife (45) of the braking arm (19) into the rail (7) and stopping, or at the very least, slowing down the descent of the door (3), with respect to the rail (7).
Abstract:
A door closer includes a closer casing, a pivot unit, and a length-variable damping cylinder. The pivot unit includes a pivot axle, a cam member, and a cam follower member. The pivot axle has a drive end portion that extends into and that is retained rotatably in the closer casing, and a coupling end portion that extends out of the closer casing. The cam member is mounted co-rotatably on the drive end portion of the pivot axle. The cam follower member is disposed in the closer casing, and is acted upon by the cam member. The damping cylinder is disposed in the closer casing, and has one end coupled to the cam follower member and an opposite end anchored to the closer casing.
Abstract:
A device for the synchronized actuation of sliding doors, provided for two sliding doors moving indistinctly in the same plane or in two planes forming any angle, consisting of two pairs of cogwheels (8-8′) and (9-9′) between which there is arranged, inside of each pair, an also cog belt (10-10′), a connection part (13-13′) fixed to the corresponding suspension grip (6-6′) of the respective sliding door being joined to each one of these belts. Joined to the two neighboring cogwheels (9-9′) there are respective cogwheels (18-18′) of a larger diameter, directly meshing with one another, to synchronously transmit motion from one cog belt (10-10′) to the other, cogwheels (18-18′) which are kept joined by means of parts (20) bridging their shafts (19-19′) and maintaining the drive transmission both when the doors are coplanar and when they form any angle.
Abstract:
An industrial sliding door has one or more panel assemblies, each panel assembly having a track panel secured to a header and a swinging panel hinged at the inner edge of the track panel to pivot in either direction about a vertical axis if the swinging panel is impacted by a vehicle such as a fork lift. Both panels can also pivot in at least one direction about a horizontal axis. A rail mounted stationary relative to the doorway at the lower edge of the door holds the lower edge of the door in proximity to the doorway and is disengagable if the door is hit from the opposite side, to permit the door panel assembly to swing about the horizontal axis away from the doorway. The swinging panel is held by a detent in the plane of the track panel in a normal position.
Abstract:
The present invention relates to a rail hidden type window and door system, including a lower window (or door) frame having a rail cover attached on a main window (or door) frame, a rail hidden by the rail cover and formed on a concave portion of a window (or door) of the main window (or door) frame of an inside of an inlet, and inlet gaskets mounted on a surface member and the rail cover; and a lower window (or door) member having a lower portion enhanced by a supporting portion, an extending portion having a roller supporting member on which a roller groove is formed, and a roller device mounted in the roller groove. Accordingly, the window (or door) is not removed from the rail and is stably opened and closed, while keeping the sealing state to minimize heat loss and preventing water from infiltrating into the interior.
Abstract:
The door reinforcement assembly includes a reinforcement plate secured to the interior surface of one of the door jambs in an overlying relationship with a projection of the door hardware. A portion of the reinforcement plate is visible when it has been secured to the door jamb, and a decorative cover is retained on the plate to conceal the visible portion thereof. The decorative cover and reinforcement plate are preferably configured so that the cover is retained without the use of fasteners (e.g., the cover snaps onto the reinforcement plate). The door hardware associated with the reinforcement plate may comprise a strike plate or an inventive high security door hinge. The high security door hinge includes a door plate fastened to the door, a jamb plate fastened to the corresponding jamb and pivotally interconnected with the door plate, and a reinforcement projection projecting transversely from each of the plates to engage and extend along the interior surface of the door or jamb.
Abstract:
A system for raising and lowering a sectional overhead door between an open position and a closed position including, a counterbalance system adapted to be connected to the door, an operator motor assembly mounted proximate to the sectional overhead door in the closed position of the sectional overhead door, at least a portion of the operator motor assembly movable between a door operating position and a door locking position, and a locking assembly (370) having an engaged position to hold the motor assembly in the operating position and a disengaged position to release the motor assembly allowing it to move to the door locking position. The system may be provided with a remote light assembly having a switchable light source in sensing communication with the operator motor such that operation of the motor activates the light source. The system is further provided with a handle assembly (515) operatively engaging the motor assembly (40) and counterbalance system (30) to selectively disconnect the motor assembly (40) from the counterbalance system (30), whereby urging of a rotatable handle (516) to a disconnect position (516′) allows the door (D) to be manually freely moveable with the aid of the counterbalance system (30).
Abstract:
An operator (10,210) for moving in upward and downward directions a sectional door (D) having a counterbalancing system (30) including a drive tube (31) interconnected with the door comprising, a reversible motor (41), a drive gear (52) selectively driven in two directions by the motor, a driven gear (54) freely rotatably mounted on the drive tube and engaging the drive gear, a slide guide (56) non-rotatably mounted on the drive tube, a disconnect (70) mounted on the slide guide and selectively movable between a first position rotatably connecting the driven gear and the slide guide and a second position disconnecting the drive gear and the slide guide, and an actuator (80) for selectively moving the disconnect between the first position and the second position.
Abstract:
A housing for an automatic door operator comprising a header section, a closing section and a terminal section. The header section includes two legs and a connecting leg which connects the two legs to one another. One of the two legs includes an end portion having a projection with a circular cross-section and an undercut. The closing section includes another projection with a circular cross-section and an indentation at one end and the terminal section at the other end. The closing section is removably attached to the header section through the engagement of the projection of the closing section with the undercut and the engagement of the projection of the one of the two legs and the indentation. The housing serves to house mechanical and electrotechnical components for the automatic the door operator.
