Abstract:
A magnetic gate latch has a multiplicity of permanent magnets arranged on a pair of disks with half of the magnets in mutual attraction and half of the magnets in mutual repulsion. These magnetic forces are used to brake and close a gate or door. One of the disks is made axially movable with respect to the other so as to assume mutual repulsion in one position and mutual attraction in a second position. The movable disk is attached to a gate or door closing member and the other disk is attached to the closing structure post or jamb. Magnetic forces in the repulsion position are used in the invention to reverse the movable disk from a mutual repulsion position to a mutual attraction position.
Abstract:
Door assemblies having magnetized bumpers for use with vehicles are disclosed. The door assemblies comprise a bumper assembly for use in a vehicle having a door that when fully opens contacts an adjacent body panel. The bumper assembly includes a bumper having a base and a distal end opposite the base. The base is configured for fixed attachment to the first exterior surface of a vehicle. The bumper is made of an elastomer and/or plastic and is configured for removable engagement with a second exterior surface. A magnet is provided with at least a portion of the magnet embedded in the body between the distal end and the base. The magnet is located within the bumper sufficiently close to the distal end to exert an attractive magnetic force sufficient to retain a door in contact with the bumper but without the magnet directly touching the door.
Abstract:
A buffer which can achieve a buffering effect corresponding to the speed of a sliding door is provided. Corresponding to the abutment force of an engagement pin 3 which is on a sliding door 2 with respect to a retaining recessed portion 67 of a hook body 61 which is slidably provided in a case body, an engagement stepped portion 71 of the hook body 61 presses a pressing member 44, and a brake pad 47 of the pressing member 44 and a brake pad 39 of a slider 31 come into sliding contact with a brake plate 28.
Abstract:
A closing and opening device for a furniture element which is mounted movably on an item of furniture comprising a lockable ejection device for moving the movable furniture element out of a closed end position into an open position and further comprising a magnetic retaining device for the movably mounted furniture element, said magnetic retaining device comprising at least two parts of which a first part is or can be arranged on the furniture body and the other part is or can be arranged on the movable furniture element and which exert a magnetic attraction force on each other at least in the closed position of the movable furniture element, wherein said first part of the retaining device, that is arranged on the furniture body, is mounted movably in the direction of the movable furniture element and is acted upon by a force storage means acting in the closing direction of the movable furniture element.
Abstract:
An elevator door assembly (20) includes a positioner (30) for controlling an orientation of an elevator door panel (22) during movement between open and closed positions. The positioner (30) biases the door in a direction generally perpendicular to the desired direction of door movement. The disclosed example includes a first positioner member (32) that remains in a fixed position. A second positioner member (34) is supported for movement with the elevator door (22). In disclosed examples, at least one of the positioner members (32, 34) provides a magnetic field that results in the biasing force. In a disclosed example, opposing polarities on permanent magnets are arranged to provide a repulsive force between the positioner members (32, 34), which provides the biasing force on the elevator door.
Abstract:
The present invention relates to a damping apparatus for moving furniture parts, for example doors, flaps or drawers. Such a damping apparatus of a compact construction which avoids a possible springing back movement of the furniture parts is provided in accordance with the invention in that the damping apparatus has at least two damping stages each having a cylinder having a piston longitudinally displaceable therein which exert a damping action of different strengths.
Abstract:
A self-restoration hinge structure is disclosed. The hinge comprises a self-restoration hinge having a linking plate, an internal linking plate, a peg nut and a magnet, characterized in that the linking plate is in combination with the L-shaped linking plate and an axle peg is used to mount the two linking plates at the axle mount thereof, the peg nut secures the axle peg within the axle mount of the two linking plates, the two linking plates are provided with a securing plate A and securing plate B and an extension plate A and extension plate B, the securing plates and the extension plates are mounted with a magnet and are installed on a door panel such that the door can be opened in a 90 degree position, the magnets having the same pole will repel each other and the magnets having different pole will attract each other, thereby when the door is pulled or pushed, the door shall be self-restored to its close position.
Abstract:
The present invention relates to a hold-open apparatus for controlling the position of a door, preferably a screen door or storm door. The apparatus is used in conjunction with a piston assembly and can maintain a door in a predetermined open position, such as about 45° to about 100° in relation to a closed position. In a preferred embodiment, the apparatus can automatically lock and/or unlock when the door reaches predetermined positions. The apparatus advantageously can be retrofitted to existing door assemblies.
Abstract:
A drive assembly in a motorized door opener includes a motor that is mounted on a mounting structure. At least one vibration isolator is provided between the motor and the mounting structure. The vibration isolator includes a first mounting fastener configured to be mounted to a mounting fastener on the motor, a second mounting fastener configured to be mounted to the mounting structure to mount the motor on the mounting structure, and an elastomeric material between the first and second mounting fasteners. The elastomeric material lies between the first and second mounting fasteners so that the isolator's two mounting fasteners are not in physical contact.
Abstract:
A magnetic type floor hinge installed on a door, comprising an installing bracket, a moving plate, a compressing spring, a longitudinal hole in the moving plate, a main shaft cam in contact with the longitudinal hole. The main shaft cam is rotatably connected to a hinge shaft of the door and rotates with the hinge shaft. The magnetic type floor hinge further comprises at least one roller attached to the moving plate, a disk rotatably attached to the installing bracket, a yoke attached to the installing bracket and arranged around a magnetic operating part, and a gear-box comprising a plurality of gears that are connected between a rotating shaft of the main shaft cam and a rotating shaft of the disk. During operation of this magnetic type floor hinge, the rotating movement of the door hinge is converted to a rotating movement of the disk.
