Door positioning system

An apparatus comprises a baseplate configured to be coupled to a door movable between an open position and a closed position. A motor with circuitry electrically coupled to the motor, and configured to be in communication with a remote computing device. At least one proximity sensor is electrically coupled to the circuitry and configured to determine the door position with respect to a door frame. A drive wheel is coupled to the motor and the circuitry. The drive wheel has an external surface, and the external surface of the drive wheel is configured to rotatably contact a ground surface. The motor is configured to be remotely activated by the remote computing device to actuate the drive wheel to rotatably contact the ground surface to reposition the door responsive to receipt of a signal.

DOOR OPENER WITH EXPOSED CONTROL PANEL
20230127272 · 2023-04-27 ·

A door opener includes a first side cover fixed to a mounting seat. A mode switching device is disposed on the first side cover and includes an anti-theft control module. A driving device is operatively connected to a door for moving the door. A control device is electrically connected to the mode switching device and the driving device. The control device includes a control panel for operating the driving device. The mode switching device is switchable to a wake-up mode only when the anti-theft control module is unlocked. The driving device is operable by the control panel only when the mode switching device is in the wake-up mode. An outer cover is coupled to the first side cover and covers an outer side of the driving device and an outer side of the control device. The control panel is exposed via a window of the outer cover to permit operation.

DOOR OPENING SPEED CONTROLLER AND AUTOMATIC OPENING STRUCTURE FOR AN APPLIANCE

An appliance includes a hinge module between a main body and a pull-down door. The hinge module includes a housing, a rotational axis member disposed in the housing serving as a center of rotation between the pull-down door and the main body, an inner link housing movably disposed in the housing that moves with the opening of the pull-down door in a direction of the rotational axis member, and a damper installed in the inner link housing, the damper including a piston and a cylinder and providing damping force according to a relative movement of the piston and the cylinder. Any one of the piston and the cylinder of the damper moves with the inner link housing and the other of the piston and the cylinder of the damper moves by a predetermined distance as the inner link housing moves and then is interfered by the housing so as not to move further, and the piston and the cylinder of the damper starts damping, wherein the predetermined distance corresponds to an opening angle of the pull-down door in which the damping is started.

Fire protection fastening device for fastening a door actuator

A fire protection fastening device for fastening a door actuator, includes a frame with a back side, which is to be oriented to a mounting surface, in particular to a door, casing or wall, wherein a mounting axis is defined vertically to the back side. The frame is formed for arrangement between a door actuator and the mounting surface or is an integral component of the door actuator (102), at least one reaction chamber formed in the frame, wherein the frame delimits the reaction chamber on the entire circumference. The reaction chamber is open on the back side and/or on a front side of the frame opposite the back side. The device further includes a drive element made from thermally intumescent material disposed in the reaction chamber and, when activated, is formed for pushing away the door actuator from the mounting surface.

Hinge system for touchless commercial appliances

A contactless laundry treating apparatus may include a cabinet having a front panel defining an access opening configured to receive laundry items, door attached to the front panel via a hinge assembly, where the hinge assembly may include a hydraulic system arranged on an interior of the front panel within the cabinet configured to engage with a connecting hook arranged within the door to selectively apply an outward force on the connecting hook to open the door and an inward force on the connecting hook to close the door.

Door closer with power close

A door closer may utilize a door closing device (e.g., spring) and a force adjustment device (e.g., a motor) in order to allow for manual door opening and assisted door closing. During operation, as a door is manually opened, the spring is loaded (e.g., compressed or tensioned) above its pre-loaded closed position state. Once manual opening is completed, the spring that is loaded during opening begins returning to the pre-loaded closed position state, and thus, moves the door automatically towards the closed position. Depending on the pre-loaded spring setting, the closing force of the door may not be enough to close the door, or to close the door with the preferred force. As such, during closing a controller may engage a motor not to drive the door directly, but to increase the pre-load of spring to increase the closing force in order to allow the door to close as preferred.

Modular add-on devices for door closers

An exemplary modular hold-open device is configured for use with a door closer comprising a body, a pinion rotatably mounted to the body, and an armature connected with the pinion. The modular hold-open device is configured to be mounted to the door closer, to selectively prevent rotation of the pinion by exerting on the pinion a resistive torque in a door-opening direction, and to cease exerting the resistive torque in response to a door-closing torque on the pinion exceeding a threshold torque to thereby permit rotation of the pinion in the door-closing direction.
