摘要:
A retractable flush-mounted apparatus which is mounted in a floor or other flat mounting surface. The apparatus includes a housing with a flange plate which is mounted in an opening in the mounting surface. A retractable member is provided within the housing which alternates between a raise position and a lower position. By pressing downwardly on the top of the retractable member, a latching mechanism is released, allowing the spring biased retractable member to move to the raised position. The retractable member is lowered by applying a force sufficient to counteract the action of the spring and move the member into the housing, whereupon the latch mechanism re-engages the retractable member to retain it in the lower position. The apparatus can be adapted for use as a security door stop or as a pop-up utility outlet. When used as a security door stop, the risk of accidental lock-out is reduced through the use of a ratchet plate and camming surface.
