A sliding door or window system includes a track. The track includes an outer housing; an inner housing within the outer housing; a guide body provided with the inner housing and configured to guide a sliding movement of a door or a window; and at least one adjustable body that is provided on the outer housing, at least partially within the inner housing, and fixed with respect to the inner housing in a vertical direction, the at least one adjustable body configured to change a height of the inner housing with respect to the outer housing by rotating, such as to change a height of the guide body.

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.

A frame for supporting a 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 are fastened to the upright columns.

A door opener includes a driving device having a first transmission member driven by a motor. A push rod is connected to the first transmission member to move therewith. A pressing rod unit is pivotably coupled to the push rod and includes a coupling sleeve, first and second end pieces coupled to the coupling sleeve, and an adjusting screw rod in threading connection with the second end piece. The first end piece is coupled with a first pivotal member coupled with a door. An end of the adjusting screw rod is located outside of the coupling sleeve and is coupled with a second pivotal member pivotably connected to the push rod. When the adjusting screw rod rotates, the adjusting screw rod moves in an axial direction of the coupling sleeve to change a length of a portion of the adjusting screw rod outside of the coupling sleeve.

A gate hinge apparatus and method adapted to be fastened to a vertical gate and to a post, comprising: a L-bolt having an elongated horizontal portion formed with thread and a transition into a vertical male member; a first bracket having a female mounting flange mounted to either the gate or the post disposed adjacent to the gate as elected by said user; a second bracket having a plate having one or more threaded means for holding and retaining said L-bolt, which is mounted to the gate or the post disposed adjacent to the gate; said L-bolt uses its vertical male member to connect to said female mounting flange; and said L-bolt has one or more nuts that are positioned on said thread on said elongated horizontal portion of said L-bolt to adjust said hinge. The method comprising: rotating the nut in a first angular direction to increase the gap width; and rotating the bolt in a second angular direction, to decrease the gap width.

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.

A hinge for door leaves of furniture which comprises a fixed part which is connectable to a side wall of the item of furniture and a movable part which is connectable to a door leaf, which are mutually connected so as to oscillate by at least one articulation axis; and a movement control device for controlling a closing/opening movement of the hinge, in the form of a damping device for damping the closing movement of the hinge or of an elastic opening device for opening the hinge. The fixed part of the hinge has a flat housing body that extends along a plane parallel to or passing through the articulation axis, the body of the fixed part being shaped so as to be insertable and fixable in a flat seat which is provided in a thickness of the side wall of the item of furniture.

The present invention relates to a device capable of guiding a stable rotational actuation between a first support bracket fixedly connected to a supporting frame side of a door frame and a second support bracket fixedly connected to the door side in a gear hinge unit constituting a rotating door, specifically, in a door hinge in which a gear hinge unit is provided between the first support bracket fixedly connected to the support frame side of the door frame and the second support bracket fixedly connected to the door side, by minimizing the compressive stress generated in the lower gear hinge unit under a neutral axis of the door and the tensile stress generated in the upper gear hinge unit above the neutral axis of the door by the rotational moment applied to the gear hinge unit due to the load of the door, it is possible not only to secure and maintain the correct opening/closing performance of the door, but also to minimize damage to parts caused by friction or friction noise in the door hinge.

A sensor unit includes a garage door sensor with a housing and a sensor. A frame is connected to the garage door sensor and is configured to be secured at one side of an opening for a garage door. A cover is configured to be secured to the garage door sensor in a removable fashion. The cover extends about at least a portion of the housing of garage door sensor in a manner which permits transmission and reception of signals at the sensor when installed.

A door mechanism for a compartment on an aircraft that includes a door with a first lower guide, a second lower guide, a first upper guide, and a second upper guide. The door mechanism includes a first lower track, a second lower track, a first upper track, and a second upper track, each having a guide track. The first lower guide, second guide, first upper guide, and second upper guide being configured to travel along the corresponding guide track to enable the door to move between open and closed positions. The door in the open position may be positioned within a portion the compartment or may be positioned above the compartment. The first and second lower tracks may include a first a second gap that enables the door to be selectively uncoupled from the first and second lower track guides permitting the door to swing away from the compartment.
