Abstract: A hook-bolt lock assembly is improved in strength by hook-bolt plates (5, 6) and can be locked without inserting a key into a lock unit (22) when the assembly is locked, so as to be improved in operability. In the assembly: a movable plate (2) is biased by a spring (3) toward its projecting direction; the hook-bolt plates (5, 6) are pivoted to a casing (1); oblique cam surfaces (16, 17) of front-end hooks (9, 10), which abut on socket members (14, 15) of a stationary frame (13) when a door (12) is closed, are oriented outward in arrangement; a leaf spring (18) interposed between the plates biases them (5, 6) swingably outward; the movable plate (2) has cam projections (19, 20) abutting on outer edges (5a, 6a) of the plates. A rear end of a rotor (23) of the lock unit (22) fixed to the casing (1) is fixed to a base end of an operating-arm plate (24); and a front-end driving projection (25) of the plate (24) is inserted in a slot (26) of the movable plate (2).

Abstract: A door locking handle assembly in which: a pivot 13 through which a button 7 is pivoted to a casing 1 is prevented from deflecting to ensure a smooth swinging action of the button 7; a leg 8 of the button 7 extends from a rear surface of the button 7 and has a hole 9 through which the pivot 13 passes; the pivot 13 also passes a hole 12 of a bearing portion 11 of a base plate 10 of a button unit 6, so that the button 7 is pivoted to the base plate 10 through the pivot 13 and biased forward by a spring 14; and, the unit 6 is received in a lower space 15 of the casing 1, and has the base plate 10 fixed to a bottom wall 4 of the casing 1 and has opposite ends of the pivot 13 abut on inner surfaces of side wall portions 5 of the casing 1 to prevent the pivot 13 from dropping from the unit 6.

Abstract: A flush handle assembly itself and a stationary frame 36 can be prevented from being damaged even when a door 35 is opened and closed in a condition in which a front end of a latch 30 is projected from the door 35. In the assembly: a handle 9 has its base end pivoted to side walls 3 of a casing 1 through a pivot 18; a leaf spring 19 keeps the handle 9 in position and urges the same to be projected from or retracted in the casing 1; the latch 30 is received in a latch casing 24 and is urged by a spring 33 to move forward; a control projection 17 of a rear surface of the handle 19 is abutted on an oblique-plate portion 32 of a side surface of the latch element 30; the projection 17 of the handle 19 is moved back and forth as the handle 19 is projected or retracted, so that the latch 30 is slidably moved horizontally along guide portions 28, 29 of the latch casing 24.

Abstract: There is provided a biaxial hinge assembly, which is mounted on a box and a door so as to be flush with a front surface of the box and that of the door. The hinge assembly prevents the door from extending outward in its closed position, and improves the door in its sealing properties to a fixed frame element. In the assembly: each of stopper hinges 5a, 5b has its one end portion inserted between bearing sleeve portions 9a and 9b of a stationary wing plate 3, and the other end portion thereof inserted between bearing sleeve portions 10a and 10b of a rotatable wing plate 4; a first pintle 13 is inserted into bearing sleeve portions 11a, 11b of the stopper hinges 5a, 5b and the bearing sleeve portions 9a, 9b; a second pintle 14 is inserted into the other bearing sleeve portions 12a, 12b of the stopper hinges 5a, 5b and the bearing sleeve portions 10a, 10b; and, stopper projections 7, 8 are formed in base-end portions of the wing plates 3, 4.

Abstract: There is provided a door locking handle assembly in which a bearing (6) is provided in a base member (3); a shaft (7) mounted in the bearing (6) is fixed to a handle (4); a lock lever (5) is fixed to the handle (4); a latch casing (18) is fixed to a front of the handle (4); a lock unit (23) is mounted in a lock-receiving portion of the handle (4); a receiving portion (32) engaged with and disengaged from a dead bolt (46) of a latch (27) in the casing (18) is formed in a front of the lever (5); and, stoppers 14 and 15 of opposite ends of the lever (5) are engaged with grooves 16 and 17, respectively; whereby a fear of overlooking an unlocked condition of the handle (4) is eliminated; and, since torque from the shaft (7) is dispersed and received through the stopper mechanism (14, 15, 16, 17), a fear of deforming the unit (23) is eliminated even if the assembly is subjected to such torque in its locked condition.
