Abstract: A split lockable hinge for a baby bed containing a first hinge wing, a second hinge wing and a lock. An outer and inner legs respectively extend downward from the first and second hinge wings. The lock comprises a plurality of receiving holes on the first hinge wing, a plurality of hooking slots on the second hinge wing which can engage the engaging pin which can be inserted through the receiving holes and the hooking slots, and a plurality of elastic members. The first hinge wing is locked to the second hinge wing by the engagement of the engaging pin to the hooking slots of the second hinge wing by the elastic force of the elastic members. The operation of the split lockable hinge is easier and more stable. The structure of it is easily made. It is easier to arrange the cloth of the baby bed and the volume of the collapsed bed is reduced after collapsing because the rod members can rotate about their long axes. With the split lockable hinge, the jumping dismantling action will not occur.

Abstract: A hinge for supporting a heavy door on a support. The hinge has a main block mounted on the support and a pair of parallel plates mounted on the door. An extender link and a rotation control link are each pivotally mounted to the main block and between the parallel plates. When the door is in the fully closed position, the main block supports the upper parallel plate. When the door is in the fully opened position, the extender link is interlocked with the rotation control link and supports the door. A compressible seal is formed between the door and the support by a sealant disposed about the perimeter of the door. The compressible seal is not exposed to shear forces.

Abstract: A non-mortised door hinge is formed of a large and a small hinge leaf pivotally interconnected about a pivot pin, the smaller leaf being of substantially the same size and shape as a central cut-out in the larger leaf for nesting within the cut-out area of the larger leaf to form a hinge of single leaf thickness. At least one of the upper and lower peripheral edges of the smaller leaf taper away from the corresponding upper and lower margins of the cut out area for increasing the clearance therebetween with increasing distance from the pivot pin. The hinge has horizontally slotted screw holes on one leaf and vertically slotted screw holes on the other leaf. The slotted holes are used to attach the hinge to a door and frame using screws, while permitting subsequent alignment of the door in its frame. At least one round (non-slotted) hole is also provided on each leaf to accept a setting screw.

Abstract: An easel hinge for supporting picture frames and the like comprises two hinge plate members each including a tubular wall. The tubular wall of one hinge plate member is inserted in the tubular wall of another hinge plate member with at least some non-congruent portions whereby the inner tubular wall can be rotated within the outer tubular wall. The outer tubular wall is open and has at its open edge a substantially straight lower end wall portion. When the inner hinge plate member strikes against the substantially straight lower end wall portion of the outer hinge plate member the plates are retained in the end angular position, and further angular displacement of the hinge plate members relative to each other is prevented.

Abstract: An appliance hinge having internal stop mechanisms. The hinge has a first member which provides a thin bearing surface on both sides of a formed cylindrical segment on the back lip of the door. The second hinge member is a molded block which mounts on the floor of the door recess on the appliance cabinet top, and has a cylindrical shaped guide slot for receiving the first member in sliding engagement. The first and second hinge members are snapped together to prevent disengagement during assembly. When the door is rotated about the hinge axis, the bearing surfaces of the cylindrical segment slilde along the guide slot until the door contacts the back lip of the slot and the edge of the cylindrical segment contacts the terminating surface of the guide slot. Cooperatively, these two stop mechanisms distribute the strain of a relatively strong opening force.

Abstract: A hinged support bracket for a drain trough is disclosed having a harness member which nests above a bracket member. Both harness and bracket members are joined by a hinge mechanism at their forward extremities, thereby permitting the harness member, containing the drain trough, to be forwardly rotated at least 180 degrees of circular arc, causing inversion of the trough and the discharge of any debris contained therein.

Abstract: A hinge having a pair of hinge plates which are reasonably connectable to each other for limited relative rotation. Each plate includes a generally flat base portion and a connecting portion disposed at an end of the base portion. The connecting portion of one of the hinge plates comprises a socket extending generally transverse of the base portion. The socket is defined in part by the flat base portion and in part by a socket wall connected at one end thereof to the base portion. The other end of the socket wall is a free end that faces generally towards and is spaced slightly from the base portion. The connecting portion of the other hinge plate is generally flat and includes a first portion that extends generally side to side of the hinge plate and is sized and adapted to fit within the socket, and a second portion intermediate the first portion and the base portion that defines a cut-out for receiving the free end of the socket wall of the one hinge plate.

Abstract: This invention is directed toward improvements in closure hinges of the type employing curved hinge sections which rotatably interconnect. A rigid link is employed at the ends of the hinge to help retain the hinge sections interconnected. Existing hinge elements are used to connect the links to the hinge. Fasteners means are employed to prevent the hinge sections from moving longitudinally with respect to each other. Spacer elements are provided to prevent the fasteners from binding on the hinge sections.

Abstract: A pair of male and female hinge halves fabricated of extruded metal sections having complemental cross-sectional shapes so as to slidingly interfit and interhookingly engage with one another define a longitudinally extending through opening at one transverse side for the reception of a hinge pin, and interhooking means at the opposite side for interhooking engagement with the complementary shape of an extruded metal frame member of a solar collector frame or the like to be adjustably supported. The interhooking engagement between the hinge halves provides a limited movement fulcrum between the two transverse sides serving to clamp the opposite side interhooking means in secure frictional abutment with the extruded metal frame member when the hinge pin is force-fitted into its through opening.

Abstract: A profiled hinge joint having joint wings designed in the form of profiled frame members, one joint wing being provided with a bead member extending longitudinally with the frame member, the other joint wing having a partially open, cap-shaped flange engaging the bead member and likewise extending longitudinally with the frame member.

Abstract: Three piece separable hinge assembly wherein, when closed or nested, a smaller flat leaf is received loosely, coplanar, within a central cut-out area of a larger flat leaf so that the composite hinge occupies the thickness of only one leaf. When this thickness corresponds to the shallow recess or seating niche of an attached structure (e.g. either door or door jamb) to which the leaf is secured, such door can be completely closed without leaving an appreciable gap between it and the adjacent wall. Each leaf, along a common edge, is formed with a jointly aligned bearing tube, which tubes house a cylindrical hinge pin having a tapered, distally converging, engagement neck and flared head. Such pin is removably insertable from either end of the tube. Longitudinally spaced along the bearing tube of the smaller leaf are a pair of tangentially projecting abutment lugs which serve to locate one connected structure (e.g. door) for automatic alignment with the other (e.g.
