A window stay, comprising: a frame plate; at least one arm coupled to the frame plate by a frame plate pivot; and a bearing plate engaged with the frame plate, the bearing plate and the frame plate together configured to be mounted to a window frame; wherein the bearing plate comprises a reinforcing insert for spreading a load applied through at least part of the at least one arm to the bearing plate; wherein the reinforcing insert is made of a material with more strength and/or rigidity than the material of the bearing plate. A window stay comprising: a frame plate; at least one arm coupled to the frame plate by a frame plate pivot; and a bearing plate engaged with the frame plate, the bearing plate and the frame plate together configured to be mounted to a window frame having a frame channel; wherein the bearing plate comprises a support member for supporting the bearing plate above the frame channel; wherein the support member is a projection that extends from beneath the bearing plate.

A guide system for guiding a movably mounted furniture part, in particular a folding or folding-sliding door, includes a longitudinal guide rail, at least one guide device via which the furniture part is movable in a longitudinal direction along the longitudinal guide rail, and at least one support on which the furniture part is mounted in an articulated manner. The at least one support is movable in a direction extending transversely to the longitudinal direction of the longitudinal guide rail, and the at least one support has a receiver for receiving the guide device and the support is movable in the mounted position into a transfer position in which the receiver is arranged adjacent to the longitudinal guide rail. A compensation device compensates for a height difference between the receiving device and the longitudinal guide rail is provided.

A patch fitting cover or cap for a patch fitting creates a substantially continuous surface toward a glass door pane using an inclined wall of the cover/cap. The patch fitting cover may be attached to a patch fitting to improve the accessibility of an associated glass door. The cover may be constructed as a retrofit cover to replace an existing patch fitting cover. The cap may be constructed to cooperate with an existing patch fitting cover such that the cap is installed on the existing patch fitting cover.

An arrangement includes a first guide system and a second guide system at a vertical distance from the first guide system. The two guide systems each has a guide and a guide body mounted to be displaceable on the guide, a carrier on which a door is to be fastened and which can be connected to the two guide bodies of the guide systems, and a compensation device by which a tilt moment of the carrier, or of the door arranged thereon, about a tilt axis is compensated for by a restoring moment. The compensation device includes a cable pull device and a pivot lever mechanism. The pivot lever mechanism comprises at least two pivot levers connected to one another in an articulated manner and pivotable relative to one another during a movement of the carrier by the two guide systems along the furniture wall.

A latch assembly connected to the drive unit of a bi-fold door retains the bi-fold door in engagement with upright columns of a building with elongated straps attached to the upright columns and rotatable latch drums mounted on a drive shaft of a drive unit. Lift devices powered by the drive unit raise and lower the bi-fold door. Latch assemblies include springs that maintain tension on the straps during the opening and closing of the bi-fold door.

A hinge mechanism is provided, including a rotary member, a first member, a second member, a first shaft, and a first slider. The first member has a first guiding channel. The second member pivotally connects to the first member and has a first recess. The first shaft pivotally connects the rotary member and the first member, wherein the first shaft has a first cavity. The first slider is movable between the first recess and the first cavity. When the first slider is located in the first recess, the first member is prohibited from rotating relative to the second member by the first slider. When the first slider slides from the first recess along the first guiding channel to the first cavity, the rotary member is prohibited from rotating relative to the first member by the first slider.

A kit for use in realigning a door connected to a jamb includes a plurality of replacement hinges having different sized gaps formed between the leaves thereof when pivoted to extend in parallel, juxtaposed alignment, including gaps that are narrower and wider than a standard gap of the conventional hinges currently used to hang the door, prior to installation. A zero gap replacement hinge may have no gap between the leaves when in the closed position. The kit may include multiple reduced gap replacement hinges with varying sized gaps and multiple enlarged gap replacement hinges with varying sized gaps. To rehang a sagging door, the top conventional hinge may be replaced with a reduced gap replacement hinge and the bottom conventional hinge may be replaced with an enlarged gap replacement hinge. The reduced gaps and the enlarged gaps of the replacement hinges may be formed using a swaging technique.

A roller system includes a body forming a first housing, the first housing includes a cavity formed between a first sidewall and a second sidewall, the first sidewall extending parallel to the second sidewall; an opening configured to receive a bearing; a first abrasive protrusion secured to a first inner surface of the first sidewall; a second abrasive protrusion secured to a second inner surface of the second sidewall; and a shaft secured to and extending perpendicular to a wheel, the shaft is secured to the bearing.

The description relates to hinged devices, such as hinged computing devices. One example can include first and second portions and a hinge assembly secured to the first and second portions. The hinge assembly can define first, second, and third hinge axes. The hinge assembly can include a first timing cord that synchronizes rotation around the first and second hinge axes and a second timing cord that synchronizes rotation around the second and third hinge axes.
