HLOCK Temporary Construction Door Latch

Abstract

A Temporary Construction door latch/lock is disclosed which is both rugged and economical. The latch includes a half circle flanged housing which acts as a bushing for a journal portion of an operator. The operator includes 2 slots (For 2″¾ and 2″⅜ size doors) to accommodate the latching and the locking pin that serves also as the handle portion to move the latch back to open the door. At the inner end of the operator, a generally cylindrical latch is placed to the interior of the housing through the face of the door to interact with the frame. The latch moves back and force with respect to the housing and is limited in movement by a spring goes inside the housing. The latch is secured to the operator by a latching and a locking pin, which means to prevent the whole latch to come apart. The housing is fixed to the door by securement means which draws the flange of the housing against the exterior of the door.
