A plastic part has a broad surface area for solvent bonding to another plastic part; the bonding surface has a groove, recess, or non-dissolvable portion for restricting the solvent to a narrow marginal edge area for uniform distribution. In one embodiment, a plastic hinge (FIG. 2) and two hinged members (64,66) are pivotally interconnected by the leaves. Grooves (52, 54) are formed on the mating surface of hinge halves. These grooves define and isolate marginal portions (56, 58) on the faces of the leaves from inner portions (60, 62). The grooves act as barriers to prevent penetration of a solvent, used for bonding the hinge leaves to the two hinged members, from the inner support portions of the leaves. When the solvent is injected into the area of contact between the mating plastic parts from the outer edge of each hinge element, e.g., by a syringe, it wets and dissolves the marginal portions and the underlying areas of the two hinged members but is restricted to the marginal areas by the grooves. Thus a plastic hinge can be bonded without mechanical fasteners and provides aesthetic consistency with the hinged members. The marginal bonding area can also be isolated by means of a recessed inner portion (84) and the principle of the invention can be used for other solvent bonded elements with broad faces, such as drawer pulls (FIG. 7) and latches (FIG. 8).

The cabinet hinge mounting plate can be fastened to a cabinet wall by means of screws passing through openings provided in it in the form of slots. The slots are configured such that the screws associated with each of them, which are threaded only on a portion of their length but have an unthreaded section adjacent the screw head, will be held temporarily by their threaded portion in a central position in the length of the slot, but when they are driven all the way in they will be displaceable lengthwise of the slot. The slots have in the area of their central portion projections protruding each toward the opposite slot edge for the purpose of holding the crests of the threads of the associated fastening screws. At their upper side facing the head of the screws the slots are provided with a rebate which is engaged by a centering section of the screw, which is formed in the transition between the head and the shaft of the screw. The diameter of the centering section corresponds substantially to the full width of the rebate.

A case assembly is provided including a pair of closely juxtaposed open-sided case halves opening toward each other and defining remote pairs of opposing marginal edge portions. Hinge structure pivotally interconnects one pair of the edge portions for relative angular displacement of the case halves about an axis extending along the one pair of edge portions and swinging of the other pair of marginal edge portions away and toward each other. The hinge structure includes adjustment structure operative to adjustably laterally displace the axis of relative angular displacement of the case halves outwardly from and back toward the open side of one of the case halves while maintaining the axis stationary relative to the other case half. In this manner, the case assembly may be disposed in horizontal position upon a horizontal table to be used as a podium, with the marginal edge portions of the case halves swingable toward and away from each other facing a person disposed adjacent the table and the top surface of the horizontally disposed case, when the case is closed, facing rearwardly and upwardly toward the aforementioned person while still enabling that person to gain access to the interior of the case from the adjacent side thereof merely by upwardly swinging the adjacent edge of the upper case half away from the corresponding edge of the lower case half.

The invention relates to hinge preparation assembly for mounting in each of the hinge mortises formed in the hinge edge of a steel door. The hinge preparation assembly includes a hinge reinforcement member having a plurality of spaced apart openings including threaded openings for mounting a leaf of a standard weight hinge set thereto. A hinge conversion member is removably mounted to the hinge reinforcement member so that upon its removal, the hinge preparation assembly is converted from a standard weight hinge preparation to a heavy weight hinge preparation, which is capable of mounting a leaf of a heavy weight hinge set thereto without requiring changing the door, modifying the hinge mortises thereof or the hinge preparation assembly.

The disclosed invention is a detachable hinge assembly, which, in one embodiment, can be employed on a cooler to provide a cooler with a removable lid. The hinge assembly includes a first attachment bar and second attachment bar coupled to the cooler body and lid, respectively, and are connected through a releasable hinge assembly which pivotably couples to both the first and second attachment bars. The releasable hinges each have an end flange constructed to pivotably couple to the first and second attachment bars and a projection having both a clip and a receiving portion. The clip from each projection is adapted to releasably couple to the receiving portion of the corresponding projection.

A hinge has a hinge-integrated stop. The hinge includes a first hinge leaf having a substantially-planar portion with a pivot edge and a top edge. The first hinge leaf includes a first knuckle extending from the pivot edge of the substantially-planar portion near the top edge. The first knuckle of the first leaf includes an inner splined surface. The hinge also includes a second hinge leaf having a substantially-planar portion having a pivot edge. A first knuckle extends from the pivot edge of the substantially-planar portion of the second hinge leaf, where the first knuckle has an inner surface and a first knuckle stop element on the inner surface. A hinge pin has a shaft having a shaft diameter and an upper splined portion having fingers extending beyond the shaft diameter and a hinge pin stop element located on the shaft below the upper splined portion.

A torque assembly includes a spindle, a cap mounted on the spindle for rotation about the spindle, and a work-hardened, plastic sleeve inserted between the cap and the spindle for constant rotation of the sleeve and cap with respect to the spindle. The torque assembly may be installed onto a hinged object and fixed object with movement along a single axis. The torque assembly may be formed by: (a) providing a spindle having a base and a rod extending from the base; (b) providing a cap member with an annular section defining an inner diameter; (c) providing an annular plastic sleeve having an inner diameter and an outer diameter; and (d) work-hardening the sleeve for a predetermined time period by compressing the sleeve between the cap and the spindle.
