Abstract: A modular chair assembly includes a seat member and at least three support leg units. The seat unit includes a seat member which has a lower surface and an upper surface opposite to the lower surface. Each of the three support leg units is detachably mounted to the lower surface of the seat member, and includes an inner axle and a hollow tube sleeved on the inner axle. The inner axle and the hollow tube are made of different materials to permit the inner axle to have a larger anti-bending strength than the hollow tube. The inner axle includes a bottom end surface for being supported on the ground.

Abstract: A hinge includes a leaf unit, first and second action units and an axle unit. The leaf unit includes first and second leaves that are rotatable relative to each other. The first leaf has a first barrel. The second leaf has a second barrel. The first and second action units are co-rotatable with the first leaf. The axle unit includes a fixing member mounted in the second barrel and co-rotatable with the second leaf, and first and second axle constituents respectively associated with the first and second action units and co-rotatable with the fixing member.

Abstract: A hinge includes a leaf unit, two action units and an axle unit. The leaf unit includes first and second leaves that are rotatable relative to each other. The first leaf has a first barrel. The second leaf has a second barrel. The action units are co-rotatable with the first leaf. The axle unit includes a fixing member mounted in the second barrel and co-rotatable with the second leaf, and two axles respectively associated with the action units and co-rotatable with the fixing member.

Abstract: A hinge device includes a hinge and a clamping unit. The hinge includes a first leaf mounted on a first object, and a second leaf pivotably connected to the first leaf. The clamping unit includes bracing and pressure plates spaced apart from each other by a clamping space for accommodating a second object. The bracing plate is removably attached to the second leaf such that the second leaf can be shifted in two mounting positions, one where the bracing plate is removed from the second leaf and the second leaf is connected to the second object, and one where the bracing plate is attached to the second leaf and the second object is clamped by the bracing and pressure plates.

Abstract: A hinge assemblage includes a leaf mechanism, an actuating unit and a damping unit. The leaf mechanism includes a first leaf, and a second leaf pivotable relative to the first leaf such that the hinge assemblage is convertible between first and second states. The actuating unit is mounted to the leaf mechanism, and generates an actuating force during the conversion of the hinge assemblage. The damping unit is mounted to the leaf mechanism for generating a damping force. The damping force generated by the damping unit during the conversion of the hinge assemblage toward the first state is different from the damping force generated by the damping unit during the conversion of the hinge assemblage toward the second state.

Abstract: An adjustable torque hinge includes a set hinge, a torque providing unit and a torque adjusting unit. The set hinge unit couples a first and second wing plate with a pivot pin. The first and second wing plates forms a pin joint with a first sleeve and second sleeve. The torque providing unit includes a torque spring to provide turn back recovery. A torque adjusting unit has a torque adjustment member. The first sleeve includes a first cam, and the torque adjustment member includes a second cam which couples with the first cam to drive the torque adjustment member to the torque spring. Conversion between the first and second sleeves enables the bearing hinge to be used in both directions, accumulating force both in normal and reverse directions to adjust the torque force for opening and closing operations.

Abstract: A door lock assembly includes: a first engaging member secured in a socket in the door frame; and a latch mechanism including a hollow mounting body mounted on the door panel, and a latch unit including a latch bolt that is retractable into the hollow mounting body, and that is operable to move relative to the hollow mounting body from a first retracted position to an extended position, in which the latch bolt extends into the socket. The latch unit further includes a second engaging member that is mounted movably on the latch bolt and that is actuated to move relative to the latch bolt from a disengaging position to an engaging position, in which the second engaging member engages releasably the first engaging member.

Abstract: A box formed from a foldable blank sheet includes a bottom panel, left and right panels, front and rear panels, and a top panel. A left reinforcing panel is hinged to the left panel and lies against a left portion of the bottom panel. A right reinforcing panel is hinged to the right panel and lies against a right portion of the bottom panel.

Abstract: A lock core unit of a weather-resistant lock apparatus includes an inner shell received in and rotatable relative to a lock shell, a plurality of locking plates received in and rotatable relative to the inner shell and cooperating to form a keyhole of the lock core unit, a locking unit operably associated with the locking plates for locking the inner shell against rotation relative to the lock shell in a locking state of the locking plates, and for unlocking the inner shell for rotation relative to the lock shell in an unlocking state of the locking plates, a latch actuator coupled to the inner shell, and a plurality of spacer plates, each of which is disposed between an adjacent pair of the locking plates. The spacer plates are made of a material with a hardness less than that of the locking plates.
