A handle is pivotally mounted to the base and has a latch projection at one end thereof. A hook is coupled to the other end of the handle and the latch projection is arranged to enter the latch recess and be lockingly retained therein as the handle is rotated to a position whereat the door is drawn firmly against the support frame for locking the door and the handle.

Abstract: There is disclosed a hinge structure for a bifold door assembly or the like, which includes first and second leaf members, the first leaf member comprising a generally flat mounting or leaf portion and a knuckle portion. The knuckle portion includes one or more and preferably a pair of coaxial spaced, knuckle portions which are of a generally semi-circular or U-shaped configuration in cross section, thus defining generally open knuckles. The second leaf member includes a generally flat mounting or leaf portion and a knuckle portion comprising a generally cylindrical closed knuckle with a pair of rod-like pins extending coaxially therefrom. The axial length of the closed knuckle is such that it may be disposed between the open knuckles of the first leaf member and the outwardly extending pins received in the open, U-shaped knuckle portions.

Abstract: A corner connector arrangement is disclosed for use in joining like vertical and horizontal frame sections for use in framing panels in the assembly of sliding doors. The connector, comprised of two clamp sections and having protrusions bearing against the frame sections, is easily attached to any corner thereof, securing said frame section with a clamping engagement.

Abstract: There is disclosed a releasable door stop assembly for a bidirectionally swinging door including a retractable stop member which normally permits opening of the door in one direction, thus acting as a stop against opening of said door in the opposite direction. The stop member is free floating and is spring biased, such that it can be retracted manually to permit opening of the door in the opposite direction. The biasing of the free floating stop member is effected by use of a leaf spring which localizes the applied force limiting same generally to the forward portions of the stop member. As such, upon manual depression, the rearward portion of the free floating stop member moves inwardly easily until a segment thereof bottoms, with the forward portion of said stop member then being rocked forward to retract the stop member entirely.

Abstract: There is disclosed a door frame construction, preferably of metal, which comprises cross channel members assembled perpendicularly with a pair of parallel upright channel members to form a rectangular frame. The respective channel members are held in assembled squared relation by a novel type of joint construction, which joint includes a pair of elongate slots formed in ones of the channel members which slots cooperating receive first detent members formed on the other of the channel members. The first detent members prevent disassembly of the joined channel member in a generally lateral direction. In addition, said slot also cooperates with second detent members received therein, which preclude relative pivotal movement between the assembled channel members and thereby serve to maintain the channel members in squared relation.

Abstract: A security hinge construction includes a pair of hinge leaves each having at least one knuckle. An electric switch is fixedly mounted within one of the knuckles and a switch operating means is disposed within the other knuckle. The switch or electrical component is sealed within its associated knuckle and an O-ring seal is disposed between the two knuckles to effectively seal the switch or electrical component from the intrusion of moisture or the like which negates the monitoring effect of the assembly if such sealing means were not present.

Through the knuckles, a bi-ended torsion spring mechanism is inserted. A first plug is affixed within one hinge knuckle and engages one end of the torsion spring mechanism. At the opposite knuckle and second spring end, the novel second plug is affixed. This second plug includes a spring-engaging finger and a capstan body adapted to fit snugly within the knuckle. Atop the capstan body is a removable head which can be grasped by a wrench or like torsioning device. After this second plug is inserted in the hinge, the spring end is grasped and torqued by rotating the plug.

Abstract: A security hinge is disclosed which includes a pair of leaves, having respectively, at least a pair of spaced end knuckles and at least one immediate knuckle disposed therebetween. Each knuckle includes a central axial bore, the bores being aligned co-axially. A pair of pins are provided, each pin having a head portion disposed in an end knuckle bore for rotation in unison therewith and a body portion thereof disposed within an intermediate knuckle bore to maintain the leaves in assembly and permit relative rotation therebetween the pin and intermediate knuckle. Stop means, are provided interiorly of the bores, against which the heads of the respective pins abut, thus preventing the pins from being driven completely through the end knuckle bores in the axially inward direction. Since the pins are recessed within the bores, and one prevents the other from being forced out of the bores in the axially outward direction, unauthorized disassembly of the hinge is precluded.

Abstract: There is disclosed a pivot and support mounting arrangement for a pivotal door arrangement which permits the door to be adjusted quite easily with respect to the door frame. The arrangement includes a pintle assembly carried by the door and a support arrangement mounted proximate to a lower corner of the door frame, and receiving a projecting portion of the pintle assembly. The support arrangement includes a bracket having an elongate channel-like opening in which is mounted a pintle support block, and selective engageable means to prevent relative movement. A recess is formed in the pintle support block to receive the pintle end portion, and spring means is associated with the support block tending to bias it upwardly. In the assembled condition the weight of the door will overcome the biasing force provided by the spring and the engageable means will be inter-engaged to preclude movement of the support block relative to the bracket.
