Abstract

693,564. Magnet fastenings. PAGE, H. E. Nov. 16, 1951 [Aug. 16, 1950], No. 3978/50. Class 44 A door or the like fastening comprises two ferro magnetic members mounted to be relatively movable and adapted to move by mutual attraction when the door is closed so as to hold the door closed In the form of Fig. 1 the magnet 1 is pivoted at 2 to a bracket 3 on the top edge of the door. When the door is closed the magnet swings from the dottedline position to the full-line position where it cooperates with an armature or keeper 5 to retain the door. When the door is pulled open the magnet drops back to the original position. A similar fastener applied to the vertical edge of the door has a spring to retain it in the releasing position when the door is open. Alternatively the magnet may be pivoted in a recess in the edge of the door and adapted to be attacted by the keeper into a recess in the door jamb. In another form a horse shoe magnet may be arranged to slide axially and co-operate with a bracket serving as a keeper. The coacting surfaces of the magnet and keeper may be corrugated to increase the retaining force. In a modification a sliding keeper on the door edge is attracted to retaining position by a fixed magnet on the door jamb. In the form of Fig. 9 the magnet 1 is mounted on the edge of one part while in the edge of the other part is a movable ball 14 captive in a tubular or trapezoidal housing and adapted to be attracted when the door closes to enter a recess in the magnet. When the door is opened the ball drops back to its rest position. In the form of Fig. 13 the magnet is formed as a bolt 17 spring loaded to the release position but attracted to engage in a socket 5 as the door is shut. When the door is pulled open the chamfered nose of the bolt returns it to the retracted position. In a modification the bolt is square nosed and is retracted for opening the door by a handle operated follower. In the form of Fig. 15 the magnet 1 is in the form of a notched abutment adapted to attract a pivoted armature so as to engage an arm 5 thereof in the notch to retain the door closed.
