A chain support mechanism for use with an openable frame component and a method of using such a chain support is provided, where a chain actuator is provided in a housing, the chain actuator including a push-pull chain which chain can bend in one direction only, the housing mounted with its longitudinal extent along one frame component with the chain attached to the openable frame component where the chain actuator may be manipulated to extend or withdraw the chain from the housing, thereby moving the openable frame component, and where the chain support mechanism includes a first arm pivotably fastened to the housing and a second arm pivotably fastened to the openable frame component, where the distal end of the first arm and the distal end of the second arm are pivotably connected by a sliding member, against which sliding member the chain may slide.

The present invention is applicable to the field of door and window technologies, and provides a top-hung casement window, including a window frame, a casement sash, and a hinge assembly. The hinge assembly includes a first hinge, a second hinge, a pivot, a connecting piece, a swing part, and a vertical limiting part. During the turning of the casement sash, the swing part swings only around the vertical limiting part, with a limited motion space. Therefore, the swing part and the casement do not shake easily. When the casement sash is open, the position of the vertical limiting part and casement sash does not change. Because all force of gravity of the casement sash is transferred to the window frame through the vertical limiting part, the bottom of the casement sash does not rub the window frame, avoiding generation of noise and abrasion of components of the hung window.

In accordance with an embodiment, a hinge system for a door of vehicle includes a hinge arm configured to be mounted between a vehicle door enclosing a vehicle compartment and a vehicle body frame surround a wall structure that defines the vehicle compartment; and a hinge shaft configured to provide an axis of rotation of the hinge arm, and configured to be located outside the wall structure.

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier. The mounting bracket may include a first mounting surface disposed at a non-perpendicular angle relative to an exterior surface of carrier when the window balance assembly is in an uninstalled configuration. The first mounting surface may be substantially parallel to the exterior surface of the carrier when the window balance assembly is in an installed configuration and the mounting bracket is disengaged from the carrier.

A sliding closure assembly includes a frame assembly, at least one sliding closure panel, a second panel, and a powered actuator. The frame assembly has a first track portion, a second track portion, and a catch portion. The sliding closure panel slides within the first track portion of the frame assembly. The second closure panel is adjacent to the at least one sliding closure panel and is positioned within the second track portion of the frame assembly. The powered actuator assembly is positioned adjacent to the second panel and entirely within the second track portion. The sliding closure panel slides within the first track portion of the frame such that an opening is formed through the sliding closure assembly when the sliding closure panel is in the opened position and the opening is closed when the sliding closure panel is in the closed position.

A frame assembly supporting an overhead door has a horizontal header connected to upright columns or posts with splice assemblies. Fasteners mounted on the columns cooperate with retainers on the splice assemblies to position and connect the columns to the header. Hinge assemblies pivotally mount the door on the header for movement between open and closed positions.

An example door closer includes a casing and a pinion rotatably mounted to the casing. The pinion is operable to rotate through a plurality of movement zones, and the door closer is configured to exert forces on the pinion as the pinion moves through the plurality of movement zones. The door closer further includes a plurality of adjustment mechanisms, each operable to adjust the force exerted on the pinion as the pinion travels through a corresponding movement zone. The casing is provided with indicia that correlate each of the adjustment mechanisms to the corresponding movement zone.

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element is coupled to the carrier and, in an uninstalled, assembled configuration of the window balance assembly, the mounting bracket is retained with the carrier.

An overhead door safety support for overhead garage doors. The overhead door safety support includes a metal frame arm, a limit switch, a mounting assembly, a junction box, a spring-loaded garage door receiving piece, a plurality of hinges, a hand lock, and a stabilizing foot. The overhead door safety support is configured to prevent a garage door from unintentionally closing and provides a visual indication of a safe condition of the garage door.
