Abstract:
A continuous, hinge having a longitudinally supported portion and a longitudinally free end. Supports in the supported portion prevent relative sliding between pivotable hinge members. Relative longitudinal sliding between hinge members in the free end is unrestricted. In a pinless embodiment, geared hinge members are meshed and held together by a clamp. The supports comprise thrust bearings that engage laterally extending surfaces in recesses in gear segments of the hinge members. In a pinned embodiment, a continuous pin extends through aligned knuckles. The knuckles of one hinge member in the supported portion longitudinally support adjacent knuckles of the other hinge member.
Abstract:
A gear hinge has a bearing fitted into opposed notches which open out of the meshed gear segments for the leaves. The bearing has blocks provided with knuckles which interlock to prevent the blocks, and the leaves as well, from moving longitudinally with respect to each other.
Abstract:
A thrust bearing assembly for a hinge structure having two geared hinge members and a clamp member. The geared hinge members are maintained in rotatable, intermeshing relation along their adjacent longitudinally extending edges by the clamp members to permit smooth and uniform movement of the hinge structure. The thrust bearing assembly of the present invention includes a pair of non-metallic interconnected inserts arranged in side-by-side order to extend laterally across and inhibit relative longitudinal movements between the hinge members. The interconnected inserts are configured to facilitate their insertion in and removal from the hinge structure while maintaining the hinge members in mesh.
Abstract:
A pinned hinge with articulating cover system and associated method for assembly are provided. In one embodiment, the hinge includes first and second hinge members pivotally coupled together. A plurality of geared bearing inserts are mounted to knuckles of the hinge members. A cover adapter clip is mounted on the knuckles that is configured to movably engage the geared bearing inserts. A cover is mounted on the cover adapter clip to complete the cover system. Opening and closing leaves of the hinge members displaces the cover to prevent interference with the hinge members during operation. The cover adapter clip and cover are resiliently structured in some embodiments to facilitate lateral assembly of the clip and cover to the hinge for convenience of installation. The geared bearing inserts further include an integral load bearing portion and provide vertical load-bearing support for the hinge.
Abstract:
A hinge including a stiffened leaf. The hinge may generally comprise a first longitudinally-extending leaf having a base portion and a mounting portion offset and preferably parallel to the base portion that defines a cavity. The mounting portion may contain at least one hole for attaching the leaf to a hinged object with a fastener. In one embodiment, the hole further includes an annular reinforcement disposed in the cavity proximate to the hole. The hole may be conical in shape and may extend into the reinforcement to receive and support a conically-shaped fastener head. The hinge is suitable for thin leaf construction and continuous full-length hinge applications.
Abstract:
A hinge that has a first mounting base for attachment to a first hinged object. The hinge also has first and second hinge members pivotally connected together. The first hinge member and the first base are configured and dimensioned for cooperatively positioning and aligning the first hinge member in a plurality of mounted positions along the base length. At least one first locking member is associated with the first hinge member and the first base for locking the first hinge member to the first base in one of the mounted positions. The hinge may also be segmented. A positioning tool may be connected to at least the first base with an attachment portion and configured for positioning the first base and attachment portion on a first hinged object at a predetermined distance from the second hinge member.
Abstract:
A pinned hinge comprising with first and second hinged members respectively including first and second leaves. The leaves have knuckles that define first bores that extend through the knuckles in a longitudinal direction. A pin is received within the bores of both leaves, pivotably joining the leaves. A cover, defining a longitudinal channel, surrounds the knuckles, protecting them. The leaves are operatively connected to the cover such that pivotal movement of the leaves displaces the cover with respect to the pin. Shanks connecting the knuckles to leaf bodies preferably have at least a double bend to retard interference between the cover and the leaves during pivoting. In one embodiment, the knuckles have gear sectors meshed with racks in the cover. In another embodiment, leaf springs operatively connect the cover to the leaves. Further embodiments include a seal disposed for sealing the cover to the hinged members when the hinge is closed. End caps block the ends of the cover. Preferably, one of these caps has a lubricant port for feeding lubricant into the channel. A cross guide, such as a cross pin, may be provided to guide the cover with respect to the pin. Some embodiments have a biasing member that pivotally biases the leaves in response to a relative position of the cover with respect to the pin.
Abstract:
A pinless hinge structure having two hinge members which are rotatable relative to each other through an angle greater than 180 degrees. The hinge members are rotatably joined along their adjacent longitudinal edges by mutually intermeshed gear segments which are maintained in rotatable association by a clamp member. Each hinge member is further configured with a leg segment extending outwardly from each gear segment. The leg segments and the clamp member are configured to allow the hinge members to rotatably traverse a greater than 180 degree arcuate path of travel relative to each other.
Abstract:
A pinless hinge structure having two hinge members which are rotatably joined for movement between open and closed positions. The hinge members have longitudinally extending gear segments which intermesh with an interior surface on a clamp member such that each hinge member moves about an axis of rotation which shifts as a function of the position of the hinge members. A thrust bearing assembly inhibits relative longitudinal movement between the hinge members and the clamp member.
Abstract:
A thrust bearing assembly for a pinless hinge structure having two longitudinally extending hinge members which are rotatory joined to each other and a longitudinally extending clamp member. The thrust bearing assembly includes a thrust bearing member having multiple bearing support surfaces which are longitudinally joined to each other. Each bearing surface is preferably non metallic and extends laterally across adjacent longitudinal edges of the hinge members to inhibit relative longitudinal movement between the hinge members.
