Disclosed is a bottom bracket assembly for a sectional door. Roller wheels engage with tracks along the sides of the doorway to support the door and guide it to move up and down or open and close the doorway. A lift cable connected with lift engagements may be provided to provide an upward bias to the motion of the door to offset the weight of the door. The roller wheels are supported by the bottom bracket assemblies connected at bottom portions of the edge stiles of the door. Each bottom bracket assembly has a bottom bracket fastened to the edge stile and a roller carrier that supports roller wheel. The connection between the roller carrier and the bottom bracket is adjustable to allow the wheel of the roller to be adjusted to a position outward of the edge of the door so that portions of the door, such as a lift bracket connected with the lift cable, do not interfere with the track.

A threshold system with an insulated thermal break device configured to provide a thermal break for insulating a door opening and related methods is provided.

A frame for an overhead door has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar. The splice assemblies connect the upright columns to the header. Hinges pivotally mount the overhead door to the header to allow hydraulic cylinders to selectively move the overhead door between an open position and a closed position.

A replacement weather seal for use with a garage door having an existing two-part weather seal previously installed on the garage door. The existing weather seal has a rigid base fastened to a support frame surrounding the garage door, and a flexible combination cover and flap portion integral with the rigid base. The replacement weather seal replaces the flap portion of the existing seal but leaves the rigid base that is fastened to the support frame. The replacement weather seal comprises a main body which attaches to the rigid of the existing weather seal. Two sealing flaps are integrally molded to opposite edges of the main body, which flaps deflect and form a weather-tight seal with both the garage door and the existing rigid base. An L-shaped curb structure connects with the main body and positions the replacement weather seal on the existing weather seal rigid base.

A bi-fold overhead door system that includes a frame, a bi-fold overhead door and a hydraulic cylinder. The bi-fold overhead door has an upper door leaf and a lower door leaf. The upper door leaf is pivotally mounted to the frame. The lower door leaf is pivotally mounted to the upper door leaf. The hydraulic cylinder has a first cylinder end and a second cylinder end. The first cylinder end is operably attached to the frame. The second cylinder end is operably attached to the upper door leaf. The hydraulic cylinder is capable of moving the bi-fold overhead door between a closed configuration and an open configuration. At least one of the frame and the upper door leaf has a slot formed therein. When the bi-fold overhead door is in the closed configuration, the hydraulic cylinder is substantially recessed in the slot.

Provided is an opening/closing device that includes a structure for inhibiting a brake engage part or a lock engage part from touching an object or the like and that prevent the perimeter of a guide rail from becoming thick due to the structure. In an opening/closing device in which a brake engage part is caused to engage with a first engaged part by a close prevention device to put a brake on the closing operation of an opening/closing body, a space adjacent to the horizontal width direction end face of the opening/closing body and continuous in the opening/closing body opening/closing direction is ensured, the space is encompassed in the opening/closing body opening/closing direction by the horizontal width direction end face of the opening/closing body, the guide rail, and the support member, and a detach spot for the first engaged part and the brake engage part is arranged within the space.

An overhead door and frame has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar. The splice assemblies connect the upright columns to the header. Hinges pivotally mount an overhead door to the header to allow hydraulic cylinders to selectively move the overhead door to an open position and a closed position.

A barricade used to obstruct the gap between a garage door, weather stripping, a threshold surface and a door frame. The barricade successfully prevents pests from breaching the barricade. The barricade uses a spring assist with low displacement force in order to conform to the changing downward or upward angle when a garage door is being operated. It also includes smooth ceramic or rubber that is magnetized to prevent chaffing to the garage door surface. This barrier stays in-place or rotates relative to the garage door face when encountering foreign objects in the path of the moving garage door. Alternatively, the barriers may be constructed of overlapping and/or abutting material configured to obstruct gaps at door frames and/or at threshold surfaces where a weather stripping and/or weather-stripping bulb provide inadequate obstruction.

A system provides a garage door that has panels pivotally interconnected and spanning horizontally across a door opening defined by a door frame. The panels have rollers that are movably engaged with tracks extending along lateral sides of the door frame. A motorized opener is coupled with the garage door and is configured to move the garage door along the tracks between an open position and a closed position in the garage door opening. The motorized opener has a controller for controlling movement of the garage door. A magnet is disposed at opposing lateral sides of the door frame. The magnets are configured to magnetically engage the garage door in the closed position and to release magnetic engagement with the garage door in response to a signal from the controller for the garage door to move to the open position.

A tilt-up door for a building having a relatively wide door opening having a door panel including top and bottom horizontal members and vertical side members connected to the top and bottom horizontal members. The vertical side members each include a pivot point, affixed to pivot translation points which move upward or downward when an actuator is activated, such that first and second cams, each connected to one of the at least two vertical side members of said tilt-up door, each affixed at its lower aspect to each side member at a position at or slightly above the center point of the door frame, and each cam extending upwardly and arcuately toward the interior of the building, to a point in space where said cam contacts a cam follower extended inwardly at approximately a right angle with respect to both the adjacent top horizontal members of the door frame, and to the Support Structure or stile to which it is fixed at its proximate end, thereby guiding the door as it is moved between its substantially open substantially horizontal position, and to be lowered into its substantially vertical substantially closed position. Each pivot translation point is lifted or lowered by means of an actuator, such as a screw, chain or hydraulic system, depending upon the needs of the user or environment, which causes the door to open or close. The door panel contains an integral track or cam which is substantially elliptical having a radius such that each integral track rides on a stationary roller which allows the panel to tilt into position. The actuation system is mounted on or in columns on either side of the door to allow the door to move into the various open and closed positions.
