A panel carriage hanger slidable along a track and having a body, rollers attached to the body to allow the body to travel along the track and a cylindrical bore in the body. The cylindrical bore has a lip including a plurality of castellations. The panel carriage hanger includes an anti-rotating sleeve inserted into the cylindrical bore, the castellations of the anti-rotating sleeve are mateable with the castellations of the cylindrical bore. The anti-rotating sleeve is movable from a first position in the bore where the anti-rotating sleeve can rotate in the bore and a second position in the bore where the castellations of the anti-rotating sleeve and the castellations of the cylindrical bore mate such that the anti-rotating sleeve cannot rotate. The panel carriage hanger includes a biasing mechanism providing a force to the anti-rotating sleeve to mate the castellations of the anti-rotating sleeve with the castellations of the cylindrical bore, a panel attachment mechanism and a rod passing through the anti-rotating sleeve, the second end of the rod supported at the second end of the cylindrical bore by a rod support member. The rod has a keyed portion mating with the keyed portion of the anti-rotating sleeve wherein rotating the rod adjusts the distance between the rod support and the panel attachment mechanism.

An adjustable guide device, which serves for guiding a sliding element, such as a sliding door, with a mounting body that is mountable on the floor, a guide member that is pivotally connected to the mounting part and is designed for interacting with the lower side of the sliding element, and a locking element, with which the connection between the mounting part and the guide member is fixable or releasable. The guide member comprises a guide body and a guide foot, which are connected with one another, which guide body comprises a guide column that is aligned along a guide axis (y) and which guide foot is seated on an upper side of the mounting body and is pivotally connected by a joint element to the mounting body so that the guide foot can be turned around a pivot axis (x), which is distant from the guide axis (y).

The present invention relates to the field of hinges and carriage mechanisms, such as a hinge and carriage mechanism adapted to hang a door, gate, panel, window or the like. The present invention is suitable for use with a means of providing height adjustment for a door and can reduce undesirable tampering and improve the security of the hinges and door assemblies by controlling the orientation of specific part of a hinge to limit access to the fastener.

The present disclosure relates to a bump stop assembly that includes a housing, a stopper, and a biasing device. The stopper is moveable relative to the housing and includes a head, a shaft extending from the head, and a plurality of recesses distributed along the shaft. The biasing device is disposed within the housing, and is operable to engage and disengage with at least one recess based on a load exerted on the stopper.

A spacer assembly includes a housing that is configured to couple to a component. The housing includes a central bore. A bumper is coupled to the housing. The bumper includes a bumper support including a shaft that extends within the central bore, and a bumper head coupled to the bumper support.

An exemplary door control assembly includes a door control and an armature assembly. The door control includes a body and a pinion rotatably mounted to the body for rotation about a rotational axis. The pinion has a radially-outer periphery and a recess is formed in the radially-outer periphery. The armature assembly comprises an armature and a coupler. The armature is rotationally coupled with the pinion, and includes an opening in which the pinion is received. The coupler is movably mounted to the armature for movement between a coupling position and a decoupling position. With the coupler in the coupling position, the coupler projects into the recess and axially couples the armature and the pinion to prevent removal of the armature from the pinion. With the coupler in the decoupling position, the coupler axially decouples the armature and the pinion to permit removal of the armature from the pinion.

A spiral balance device for sash windows has a pipe inside of which extends a spiral rod having a screw section. A lower end of the spiral rod extends through a slot in a coupling rotatably disposed inside the lower end of the pipe and projects from the lower end of the pipe. A torsion spring has an upper end fixed near the upper end of the pipe and a lower end fixed to the coupling. A fixing member is fixed within the upper end of the pipe, and an adjustment member rotatably disposed below the fixing member engages with the upper end of the spiral rod. A ratchet mechanism disposed between the fixing member and adjustment member allows rotation of the adjustment member in a direction of winding the torsion spring and prevents rotation of the adjustment member in a direction of unwinding the torsion spring.

A hinge includes a hinge arm, a hinge cup, at least one resilient member, and a retaining member. The hinge cup is pivotally connected with respect to the hinge arm and includes a receiving room. The resilient member is mounted in the receiving room of the hinge cup. The retaining member is mounted at the resilient member.

A hanger hinge for a folding door, window or similar closure having one or more panels, the hanger hinge comprising: A hanger bolt having a receiving portion in a lower end thereof adapted to receive at least a portion of an adjusting tool; A sleeve adapted to be supported on the lower end of the hanger bolt; At least one hinge leaf pivotally mounted on the hanger bolt and adapted to be fixed to a respective panel; and A locking mechanism comprising a locking member movable axially between a locked condition in which the locking member is engaged with the sleeve in a manner to substantially preclude rotation of the hanger bolt relative to the sleeve, and an unlocked condition in which the locking member is disengaged from the sleeve by axial insertion of the adjusting tool into the receiving portion, thereby freeing the hanger bolt for rotation relative to the sleeve.

An adjustable guide device, which serves for guiding a sliding element, such as a sliding door, with a mounting body that is mountable on the floor, a guide member that is pivotally connected to the mounting part and is designed for interacting with the lower side of the sliding element, and a locking element, with which the connection between the mounting part and the guide member is fixable or releasable. The guide member comprises a guide body and a guide foot, which are connected with one another, which guide body comprises a guide column that is aligned along a guide axis (y) and which guide foot is seated on an upper side of the mounting body and is pivotally connected by a joint element to the mounting body so that the guide foot can be turned around a pivot axis (x), which is distant from the guide axis (y).
