Abstract
An arresting arrangement is mountable on the lower edge of a door adjacent to the floor and is movable between an inoperative and an operative position. A biasing spring permanently biases the arrangement to the inoperative position, and a latching arrangement serves to releasably latch the arresting arrangement in the operative position. An electromagnet controls the operation of the latching arresting arrangement.
Claims17
A device for arresting a door, particularly in an open position, comprising arresting means mounted at a lower portion of a door adjacent to a floor for movement between an inoperative position in which said arresting means is disengaged from, and an operative position in which said arresting means engages, the floor;
- biasing means for permanently biasing said arresting means toward said inoperative position thereof;
- latching means mounted at the lower portion of the door for displacement between a first position in which said latching means engages said arresting means to thereby prevent movement of the latter toward said inoperative position thereof, and a second position in which said latching means releases said arresting means for movement toward said inoperative position, and including a magnetically attractable portion;
- and electromagnetic means at the lower portion of the door and operative for magnetically attracting said magnetically attractable portion of said latching means to thereby hold said latching means in said first position thereof.
A device for arresting a door, particularly in an open position, comprising arresting means including a component formed with a plurality of teeth and mounted at the door adjacent a floor for movement between an inoperative position in which said arresting means is disengaged from, and an operative position in which said arresting means engages, the floor;
- first biasing means for permanently urging said component toward said inoperative position thereof;
- latching means including a latching member mounted at the door for displacement between an engaging and a disengaging position, a slide member mounted in said latching member for displacement between an extended and a retracted position, and second biasing means for urging said slide member toward said extended position thereof;
- third biasing means for urging said latching member toward said engaging position thereof so that said slide member engages one of said teeth of said component when in said extended position thereof;
- and electromagnetic means including at least one electromagnet operative for holding said latching member in said engaging position thereof when energized.
