Abstract:
A direction switchable ratchet device for a door operator is provided. The door operator includes an electric motor, an electromagnetic brake and the direction switchable ratchet device. The direction switchable ratchet device comprises a first and second direction restricting devices and a manually operable mechanism. A drive shaft of the electric motor is braked by a brake baffle disk when the electric motor is electrically de-energized and is released when the electric motor is electrically energized. The first and second direction restricting devices are provided to prevent the drive shaft from being rotated clockwise and counter-clockwise respectively by holding the brake baffle disk. In the event of power failure, the manually operable mechanism is effective to open the door once a pawl of the direction restricting device at the free side is retracted. The manually operable mechanism of the door operator is prevented from being incorrectly mounted in a cost-effective manner.
Abstract:
A home appliance having a door which may be opened and closed, and more particularly, a home appliance to assist a user in easily opening or closing a door is disclosed. The home appliance includes a cabinet having a chamber in which an object is received or retrieved, a door to open or close the chamber, and a handle assembly to be rotated relative to the door during opening or closing of the door, wherein rotation of the handle assembly causes the door to be rotated about a door rotating axis.
Abstract:
Certain embodiments provide systems and methods for unlocking, opening, closing and locking a vent sash. The system may include a push arm configured to extend to open the vent sash and retract to close the vent sash. The system may include a guide arm configured to extend to unlock the vent sash and retract to lock the vent sash. The system may include a handle extension configured to radially rotate substantially one hundred eighty degrees in a first direction on a single plane to extend the push arm and the guide arm. The handle extension may be configured to radially rotate substantially one hundred eighty degrees in a second direction on the single plane to retract the push arm and the guide arm.
Abstract:
Disclosed is a refrigerator capable of adjusting a step difference of a refrigerator door. The refrigerator includes a body, a door opening/closing the body, a hinge member having a hinge shaft to be coupled with the door, a mounting member fixed to the body to receive the hinge member, and an adjusting unit coupled with the hinge member to adjust a step difference of the door by moving the hinge member.
Abstract:
A system for controlling vehicle opening/closing element has a radiation block for irradiating near-infrared light to a peripheral region of an opening/closing element; a photographing block that photographs an image irradiated with the near-infrared light; a hand region extraction block that extracts a user's hand region from brightness of an image photographed by the photographing block; a motion detection block that detects motions of the user's hand from the extracted hand region; and a control block that determines whether or not the detected motions coincide with previously-set predetermined motions and that commands operation of the opening/closing element in accordance with the determined motions.
Abstract:
The present disclosure discloses a door closer stopper, comprising a housing mounted around a door closer, a finger press block assembly and a stop assembly disposed in the housing. The housing is provided with a slot and an opening; The finger press block assembly comprises a press block and a rotary press block hinged to the slot of the housing, and a positioning mechanism limiting the rotary press block at a position propping a catch plate; The stop assembly comprises the catch plate with a central through hole to allow the pull rod of the door closer to extend therethrough, the catch plate is perpendicular to the pull rod and has a top end in a scope of movement of the rotary press block, the rotary press block can abut against the top end of the catch plate to make the catch plate incline when the rotary press block rotates to a certain position. The present disclosure is overly compact and reasonable in structure, simple and easy to operate, and practical, safe and reliable. The user does not need to replace the original door closer and only needs to additionally install the present disclosure to perform an easy switch between several working states. The door can be positioned and remain an open state at any opening angle, and can quickly resume an auto door closing function. The present disclosure is adapted for various ordinary tubular door closers and has a broad application prospect.
Abstract:
A multi-function camera system comprises a camera fixed to a vehicle component on a side of a vehicle for photographing a side area of the vehicle; a condition determination unit for determining execution conditions of a plurality of function units; an obstacle detection unit to function based on a determination result from the condition determination unit for detecting, through image recognition, an obstacle present in the vicinity of the vehicle or approaching the vehicle based on a captured image of the camera; and an individual authentication unit to function based on the determination result from the condition determination unit for ascertaining, through the image recognition, whether or not a person having reached the vehicle matches with a user who has been registered at the vehicle beforehand based on the captured image of the camera.
Abstract:
An access control system for a passageway having a passageway barrier including an active infrared sensor device and a locking mechanism for selectively locking and unlocking the passageway barrier. The active infrared sensor device includes an infrared emitter, an infrared receiver having one or more position-sensing photodetectors operative for receiving infrared light and generating a signal corresponding to a position and/or intensity of the reflected infrared light, and a processing unit operative for detecting a change between a first signal generated by one or more position-sensing photodetectors after receiving reflected infrared light at a first location on one or more position-sensing photodetectors and a second signal generated by one or more position-sensing photodetectors after receiving infrared light reflected in response to the object moving into the surveillance area and for controlling an operation of a locking mechanism based on the change.
Abstract:
In a four-seat coupe, it is inconvenient for a rear-seat occupant to get in/out of the vehicle while a front-seat occupant is seated. In the present invention, the length of each door of the four-seat coupe is set, so that the rear-seat occupant can get off/on the vehicle while the front-seat occupant is seated. The door is provided with detachable first opening/closing means at its front and rear end portions. The first opening/closing means at the front end portion of the door is adapted to be released when the front-seat occupant gets off/on the vehicle to allow the first opening/closing means at the rear end portion of the door to support the door so that opening/closing motion can be performed. Also, the first opening/closing means at the rear end portion of the door is adapted to be released when the rear-seat occupant gets off/on the vehicle to allow the first opening/closing means at the front end portion of the door to support the door so that opening/closing motion can be performed.
