A three-dimensional adjustable door mounting system and method for aligning and installing a hinged door within a frame. In one embodiment, the mounting system includes one or more captive nuts mounted to the door. The captive nut includes a movable adjusting plate retained by a stationary holding bracket mounted to the door. A threaded fastener inserted through a hinge door leaf and into the adjusting plate allows an installer to move and adjust the position of the hinge relative to the door in a first plane. In other embodiments, captive nuts may further be affixed to the door frame. A threaded fastener inserted through a hinge frame leaf and into the adjusting plate allows an installer to move and adjust the position of the hinge and door relative to the frame in a second plane different than the first plane.

Adjustable door mounting system

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.

Hinge with articulating cover system

A hinge including leaves configured to facilitate adjusting the mounting position between hinged objects. In one embodiment, the hinge may generally include first and second leaves pivotally connected together. The leaves define mounting holes that receive fasteners to mount the leaves to the hinged objects. The mounting holes are preferably configured to provide adjustment of the leaves and hinged objects in at least two directions, which may be horizontal and vertical. In one embodiment, the hole shapes preferably may include horizontal slots, vertical slots, round holes, and combinations thereof. Other shapes may be used. When a fastener is partially inserted into a hinged object through a slotted-type mounting hole, for example, the hinged object is slideable relative to the leaf and the other hinged object. By employing a preferred sequence of installation steps, the installer may readily optimize the alignment between and mounting of the hinged objects. In one embodiment, the hinged objects may be a door and a door frame. A method of installation using the specially-configured leaves is also provided.

Hinge attachment system and method

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.

Hinge with stiffened leaf

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.

Hinge mounting system

A slim profile covered pinned hinge is provided which comprises a first hinge member, a second hinge member, and a mechanically articulated cover. The first and second hinge members are pivotally connected by a pin. The first and second hinge members may each further comprise a leaf for attachment to a hinged object, a door or door jamb for example, and at least one knuckle through which the pin may be received. The cover may be elongated and has an internal cavity, thereby allowing the cover to be slipped over the hinge concealing the knuckles and joints therebetween of the hinge members. The cover has two ends and may be mechanically coupled to the pin at one or both ends. In one embodiment, at least one end of the pin may have at least two gears comprising a gear segment. The ends of the cover may have at least one gear rack to engage the gears on the end of the pin. Angularly opening and closing the first and second hinge members moves the cover with respect to the pin, providing additional clearance to allow for the leaves of the hinge members to swing as the hinge is operated.

Covered pinned hinge

Two hinge members are pivotally mounted about edges of a clamp. Thrust bearings are disposed in recesses in both hinge members for preventing relative movement between the hinge members along the clamp length. Antirotation portions of the bearings resist rotation of the bearings caused by torque produced by the hinge members on the bearings. In one embodiment, the clamp has a longitudinal key that is engaged within a keyway in the bearings that prevents bearing rotation. In another embodiment, the bearings have a longitudinal free extension on at least one side of a bearing body. The extensions increase the effective length of the bearings, limiting rotation. The extensions are preferably meshable with other bearings for transferring torque between adjacent bearings, or bearings may overlap the extensions. More preferably, the extensions are lockable to other bearings. The clamp may have notches extending between its walls and a clamp base such that the clamp base remains unaltered upon bending of the walls. Additionally, the thrust bearings may have lateral free extensions that increase the width of the bearing and that have a smaller width once mounted within the clamp to reduce gaps therebetween.

Torque resistant hinge bearing

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.

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.

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.

Gear hinge with knuckle-type bearing

A pinless hinge structure including a pair of longitudinally extending hinge members which are rotatably joined to each other and a longitudinally extending clamp member for maintaining said hinge member in rotatable association relative to each other. A torsion spring engages each hinge member and provides a self-operating feature to the hinge structure.

Pinless hinge structure with self-operating features

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.

Pinless hinge structure rotatable through an extended arc of travel

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.
