Abstract: A self-closing hinge comprises a pair of hinge leaves pivotally interconnected by an offset hinge pin. One leaf has a flanged head projecting substantially radially with respect to a sleeve of the other hinge leaf, within which the hinge pin is mounted. The external surface of the sleeve serves as a cam surface against which a follower element carried on the head of the other leaf is biased. The cam follower comprises a tubular spring-steel member oriented parallel to the hinge pin and generates a force through the head of the other leaf along an axis distally offset relative to the axis of the hinge pin. During closing of the hinge the follower is brought into registration with a pocket formed in the sleeve to effect a rocking movement of the follower about one edge of the pocket to generate a self-closing moment.

Abstract: Improvements in separable hinge mechanisms. A problem with such mechanisms is that, over a relatively long hinge axis, the hinge pins tend to bind due to misalignment. The invention provides positive alignment and minimizes off-center loads. Mechanism (8) has two opposing integral leaves (10, 20). Each leaf (10, 20) has a plurality of knuckles (12, 30, 32, 32') attached thereto. These form a plurality of axially spaced hinge stations (18). Each station (18) has a corresponding hinge pin (28). Each pin (28) is attached to one of two slide bars (22) that are mounted on leaf (20) for sliding movement parallel to axis (X). Bars (22) are mounted by a center mounting lug (42) and guide rod (46) that carries a spring abutment (26) for each bar (22). Leaves (10, 20) are separated by squeezing toward each other two adjacent finger tabs (24), one on each bar (22). This compresses two springs (48) mounted on rod (46) which bias the bars (22) and pins (28) into a position in which leaves (10, 20) are connected.

Notably, final assembly of the pivotal connection provided is effected with a suitable adhesive, thus permitting manual or hand-fitting of the various components for final assembly.

Abstract: A hinge has a pair of leaves, one of which has a spaced pair of knuckles and the other has a central knuckle disposed therebetween. Disposed in the single knuckle are a pair of tubular bushing inserts received in opposite ends of its passage and having radial flanges disposed between the adjacent knuckles. The two knuckle hinge leaf is engaged with a pair of hinge pin elements extending inwardly from the opposite end of the leaf so as to prevent relative rotation therebetween, while the hinge pin elements extend into and are freely rotatable in the inserts. In the method of assembly, the bearing inserts are placed in the single knuckle leaf, and the two knuckle leaf is then aligned therewith and the hinge pin elements are inserted and engaged with the two knuckle leaf to prevent relative rotation therebetween.

Abstract: First (12) and second (42,62) body portions are each attached to a structural member. The first body portion (12) includes trunnions (18) that are slidably received in corresponding channels in the second body portion (42,62). The second body portion (42,62) includes a base member (62) and a pivot member (42), which cooperate to form the channels. The pivot member (42) has an open position and a closed position. A spring (82) biases the pivot member (42) in its closed position. A lever (44) moves the pivot member (42) against the force of the spring (82) into its open position. When the pivot member (42) is in its closed position, it blocks portions of the channels, thereby locking the trunnions (18) into one of two lock positions in the channels. When the pivot member (42) is in its open position, the trunnions (18) may slide in the channels from one lock position to another or out of the channels to disengage the two body portions.
