Abstract:
The invention relates to a gate or door drive housing with a basic carrier body for preference in the shape of a bowl or shell, to which various different drive components can be secured, and a cover hood which can be connected to the basic carrier body. According to the invention, a housing extension for accommodating additional and/or larger drive components can be connected in a releasable manner in an exact fit to the basic carrying body.
Abstract:
A door supporting device for supporting a door in a door frame is disclosed. The device includes an upper unit, which further includes a frame attachment member to be fixed to a door frame header; a frame-side connector member rotatably connected to the frame attachment member and having an adjuster aperture; a door-side connector member connected to a rotation shaft extending from the door and detachably connected to the frame-side connector member; and an eccentric bolt connected to the frame attachment member through the adjuster aperture. The eccentric bolt is exposed from the adjuster aperture with a portion of the eccentric bolt being in contact with periphery of the adjuster aperture. Rotation of the eccentric bolt makes the frame-side connector member to rotate to adjust alignment of the door with respect to the door frame in a direction of depth of the door.
Abstract:
The invention is in a device for monitoring the position of a swinging door that is mounted on a stationary frame, the device essentially comprises a magnet and magnetic proximity sensor which are mounted in coaxially aligned relation on a pair of opposing leafs of a hinge. Means are provided for moving the magnet to and from the sensor to correspondingly vary the gap or spacing between them.
Abstract:
A door holder and stop which utilizes an elongated arm and track to retain the door in a closed position. The arm, through the use of a plate, is attached to a door frame. Pivotally and slidably connected to the arm is the track, having a return end and a closure end. The track is fixably attached to a door. At one end, the track has a locking mechanism for retaining the door in a closed position.
Abstract:
A magnetic coupling system for securing a temple to an eyeglass hinge includes a pivotal flange on the rear end of the eyeglass hinge and one clipping structure formed on the front end of the temple. One coupling magnet is provided in the pivotal flange of the eyeglass hinge. The clipping structure includes a pair of opposed pivotal flanges spaced one from the other to capture the pivotal flange of the eyeglass hinge therebetween and two magnets respectively secured in the pair of opposed pivotal flanges for respective magnetic coupling to the coupling magnet in the pivotal flange of the eyeglass hinge. Therefore, the temple is pivotally coupled to the eyeglass hinge in a magnetically reinforced manner.
Abstract:
A control mechanism includes a set of permanent magnets located within a cylindrical housing, the magnets being carried on a shaft which extends within the housing and is movable axially relative to the housing. The magnets are arranged in repulsion configuration and are coupled to the shaft and moved together as the shaft is moved relative to the housing manually from a stationary or retracted position to an extended position. Upon release of the shaft, repulsion forces produced by the magnets cause the magnets to move apart, moving the shaft relative to the housing from the extended position to the retracted position. In one embodiment, the control mechanism is coupled between a door and a door frame and operates as a door closer. In other embodiments, the control mechanism operates as an opening mechanism for opening the cover of a container, the opening mechanism also acting as a closer as the cover is being closed, to assist in closing the cover.
Abstract:
This device comprises mechanical link including a pawl (25) establishing a rigid drive link between a driving input member (2) and an output member (22), interacting with a prestressed element (31) which tends to hold the pawl in connection with the driving input member or with the driven output member, for so long as the force transmitted by the pawl remains below a predetermined value; this system automatically interrupts the kinematic drive chain of the movable member in the case of a force exceeding a predetermined value. This arrangement makes the device practically insensitive to friction and eliminates the uncertainty on the threshold of the triggering force.
Abstract:
A device for pivoting a structural member about the axle of a hinge, and hinge being fitted to the structural member and to an object so as to permit pivoting of the member relative to the object, the member having at least one edge portion which is magnetic and which swings along a planar path when the member pivots about the hinge axle relative to the object, the device including: an arm pivoted for rotation about an axis which is parallel to the hinge axle; at least one magnet carried by the arm, the arrangement being such that, upon pivoting of the arm, the magnet moves in a path parallel to the path of the magnetic edge portion of the member and spaced a small distance from the path of the magnetic edge portion to provide an air gap between the magnet edge portion and the magnet, whereby the magnet and the magnetic edge portion are out of contact with each other but can be magnetically coupled so as to move simultaneously in their respective paths upon pivoting of the member relative to the body; and a mechanical for swinging said arm about its pivot axis.
