Abstract:
The invention relates to an emergency opening device for a preferably automatic two-panel sliding door having an energy storage element embodied by a rubber belt (6). Said rubber belt (6) is on one side irremovably fixed in a support (9) and on the other side removably fixed to a holding device (7) by means of a slide (8). During normal operation of the sliding door the pretensed rubber belt (6) has no effect. The holding device (7) releases the slide (8) with the rubber belt only in an emergency, such as a fire or power failure. The slide (8) interacts with the pulley carriages (5b) of the sliding door and by means of the energy stored in the rubber belt (6) moves the sliding panels (1a, 1b) into the fully opened position. To prevent a sudden, severe impact of the slide (8) against the pulley carriage (5b) the slide (8) comprises a friction brake (82, 83, 84). This brake (82, 83, 84) is released by a control device (56) only after the slide has contacted the pulley carriage (5b) so that the entire energy stored in the rubber belt (6) is then able to act upon the pulley carriage (5b). When the emergency is over the rubber belt (6) is tensed during the first closure of the sliding door by the movement of the pulley carriage (5b) and again fixed to the holding device (7).
Abstract:
A clutch, comprising drivingly rotating bodies (11; 52; 83; 202; 302) connected to a drive source (2) such as a motor and drivenly rotating bodies (12; 53; 85; 204; 303) engaged directly with the drivingly rotating bodies, wherein both rotating bodies are stored in housings (13; 51; 82; 201; 301), lock members (14; 54; 86; 119; 205; 304) comprising rollers and balls are disposed between the drivenly rotating bodies and the housings, when the drivenly rotating bodies themselves are rotated, the lock members are held between the drivenly rotating bodies and housings so that a rotation of the drivenly rotating bodies relative to the housings is prevented, when the drive source rotates the drivingly rotating bodies, the lock members reset the holding condition so as to allow the drivingly rotating bodies to rotate the drivenly rotating bodies relative to the housings, whereby the clutch can prevent securely a transmission of rotation from the drivenly rotating bodies to the drivingly rotating bodies and, in addition, strengths required for both rotating bodies can be reduced.
Abstract:
A reducing motor including a rotor with an armature shaft, a reducer housing (2) containing a gear wheel (3) engaging a worm on the shaft, and a shock absorber (5) housed in the gear wheel and rotationally integral therewith. The unitary shock absorber has circumferential notches (8) engageable both by radial flanges 87) on the gear wheel and by elements (10) for driving an output member (11), and chamfers (90) are provided on the edges of the notches to ensure gradual torque-dependent angular deflection of the shock absorber and make it easier to mount the same automatically on the hub of the gear wheel.
Abstract:
The invention relates to a Bowden tube window winder with compensation for cable length, which also compensates using simple means for a comparatively high level of cable elongation without excessive twisting of the cable loop. Said Bowden tube window winder is characterised in that a common locking member (10) is associated with the cable sockets and links the force of the two cable sockets (110) with the result that a movement to compensate for play of at least one cable socket can only occur when both cable sockets are substantially unloaded.
Abstract:
A safety device, particularly intended to be used in roll-up doors to cause reversal of the door closing movements in case an obstacle obstructs the path of movement of the door. The device (6) comprises at least a couple of photoelectric cells (7) which are arranged at a certain distance from the closing edge of the door leaf (1) in alignment with the door leaf (1) by means of a support arm (9) which is displaceable in the direction of closing of the door.
Abstract:
An overhead door operator system (1) for opening and closing an opening (2), comprising a door frame (3) comprising a first frame section (4) at a first side (7) of the opening (2) and a second frame section (6) at a second side (5) of the opening (2). The operator system further comprises a door (8) arranged to be moved between an open and closed (C) position, the door (8) being movably connected to the door frame (3) and a drive unit (10) mounted on the door (8), the drive unit (10) comprising at least one motor (11) arranged to move the door (8) from the closed position (C) to the open position (O). An elongated transmission member (19) extends along the first side (7) of the opening (2) and the first frame section (4). The drive unit (10) further comprises a driven transmission member (18) in driving connection with the motor (11).
Abstract:
An example door stop mechanism is provided. The door stop mechanism includes a body, a connection member, a spring, and a brake. The spring is coupled to the body and the connection member. The brake is positioned adjacent to the body. The brake moves between an engaged position via a spring force of the spring that causes the body to interact with the brake such that the brake contacts a track of an overhead door and an disengaged position via a force that acts against the spring force to pull the body away from the brake such that the brake moves away from the track to allow the overhead door to move
Abstract:
A door assembly may include a first sidelite configured to be operably coupled to a first door jamb, a second sidelite configured to be operably coupled to a second door jamb where the first and second sidelites are disposed in a common plane and defining a door opening between the first and second sidelites, a first sliding panel, a second sliding panel where the first and second sliding panels are movable from a closed position disposing the first and second sliding panels to block access through the door opening and an open position in which the first sliding panel is proximate the first sidelite and the second sliding panel is proximate the second sidelite, and are disposed in a second plane parallel to the common plane in both the open and closed position, a first partial door panel disposed in a third plane opposite the second plate relative to the common plane, and a second partial door panel disposed in the third plane, the first and second partial door panel being movable from being a closed state in which the first and second partial door panels at least partially block access through the door opening and an open state in which the first partial door panel is proximate the first sidelite and the second partial door panel is proximate the second sidelite. The first and second partial door panels are each operably coupled to a biasing assembly that biases the first and second partial door panels toward the open state, and the first and second partial door panels are configured to be transitioned to the closed state by manual operation against a force of the biasing assembly.
Abstract:
An electronic lock device according to one embodiment includes a first magnetometer, a second magnetometer, a dynamic ferromagnetic component positioned between the first magnetometer and the second magnetometer, a processor, and a memory comprising a plurality of instructions stored thereon that, in response to execution by the processor, causes the electronic lock device to read sensor data from the first magnetometer and the second magnetometer, modify the sensor data to generate compensated sensor data that compensates for magnetic noise generated by the dynamic ferromagnetic component, and determine whether the door is in a closed state or an open state based on the compensated sensor data.
