An embodiment of a slat connection system for a roller shutter includes a plurality of slats pivotably hinged together, where each slat of the plurality of slats includes a slat body having a first edge and a second edge opposing each other, the inner hinge provided at the first edge, and an outer hinge provided at the second edge, where the inner hinge of a first slat of the plurality of slats is pivotably received in a hinge groove of an outer hinge of a second slat of the plurality of slats with a sealing member interposed between the first and second slats, and where the inner hinge and the sealing member are each positioned in parallel to a flat outer slat surface.

In example a panel for an overhead sectional door is provided. The panel includes a laminate core, a laminate skin, and a universal fabric hinge. The laminate skin is coupled to two opposing sides of the laminate core. The universal fabric hinge is coupled to the laminate skin to connect the panel to an adjacent panel of the overhead sectional door.

The invention comprises a double roller garage door panel hinge and method for same. The hinge comprises a first hinge half and a second hinge half that are removably and pivotally connected to each other by a clasp formed by the second hinge half; the first hinge half further comprises a first half hinge base that supports a first roller support tube up and away from a first half hinge base, the first roller support tube rotatably supports a first garage door roller; the second hinge half further comprises a second half hinge base that supports a second roller support tube up and over the second half hinge base, the second roller support tube rotatably supports a second garage door roller; wherein the first hinge half is attached to first garage door panel and the second half hinge is attached to an adjacent garage door panel.

A hinge assembly utilizes first and second hinge members. Each hinge member has an attachment body and a pair of laterally spaced apart opposite arms. Each arm has an aperture for receiving a cylindrical member for rotatably coupling the hinge members together so that the hinge members are rotatable about the cylindrical member. The arms of each of the first and second hinge members are spaced apart the same distance, with each arm of having an outer face that faces away from the opposite arm and an inner face that faces the opposite arm. The hinge members are configured so that each arm of each hinge member interfaces with one arm of the other hinge member with the arms of the hinge members being in an offset arrangement wherein the outer face of only one arm of each hinge member interfaces the inner face of only one arm of the other hinge member.

A sectional and side sectional garage door hinge and a method of using thereof is disclosed. The sectional and side sectional hinges may be attached to two garage door panels that are above each other and allow such garage door panels to latch and unlatch from each other. Each of the sectional and side sectional hinges may have an upper base attached to the upper garage door panel and a lower base attached to the lower garage door panel. The upper base and the lower base may have engagement members that latch and unlatch from each other. When the sectional and side sectional hinges are in the unlatched orientation, the two garage door panels may be separated from each other vertically to create an elevated opening between the garage door panels of the garage door.

Methods and systems (e.g. as kits, installations, or other protocols) are described in relation to lockable hinges for use in panelized enclosures. A system includes a plurality of purpose-built lockable hinges each configured to connect two adjacent panels. When the hinges are in a locked state the adjacent panels may move along a track together. In an unlocked state the panels may move toward or away from each other along the track. The method may include kit installation or otherwise controlling the selective movement of door panels, such as for turning a fenced and ventilated enclosure into a structure with a retractable door that (externally and superficially) seems conventional.

A stabilization roller bracket is positioned adjacent to a hinge and supplements a hinge in coupling a roller to a movable barrier. The stabilization roller bracket includes a base configured to be coupled to an inner surface of the movable barrier. The base includes a main body and a frangible portion. The stabilization roller bracket also includes at least one wall extending from the base and including a plurality of stem-receiving holes, each of the plurality of stem-receiving holes spaced a different distance from the base and configured to receive a portion of a stem of a roller for the movable barrier and space the roller from the inner surface of the movable barrier.
