An overhead door operator system (1) for opening and closing an opening (2), comprising a door frame (3) comprising a first frame section (4) at a first side (7) of the opening (2) and a second frame section (6) at a second side (5) of the opening (2). The operator system further comprises a door (8) arranged to be moved between an open and closed (C) position, the door (8) being movably connected to the door frame (3) and a drive unit (10) mounted on the door (8), the drive unit (10) comprising at least one motor (11) arranged to move the door (8) from the closed position (C) to the open position (O). An elongated transmission member (19) extends along the first side (7) of the opening (2) and the first frame section (4). The drive unit (10) further comprises a driven transmission member (18) in driving connection with the motor (11).

A driving device for a door opener includes a motor driving a first transmission member to rotate. Rotation of the first transmission member causes lateral displacement of a sliding member which moves jointly with a connecting rod. A return spring is mounted around the connecting rod. An adjusting ring is in threading connection with the connecting rod and abuts against the return spring. When the first transmission member does not rotate, rotation of the adjusting ring causes displacement of the adjusting ring in the lateral direction to change an extent of pre-compression of the return spring. When the first transmission member rotates in a direction, the connecting rod and the adjusting ring together move in the lateral direction towards the first transmission member, and the return spring is compressed. When the first transmission member rotates in a reverse direction, and the return spring restores its length.

A fastening device for a vehicle window lifter includes at least one guide rail for guiding a driver for a window glass or pane. A joint piece has two joint pins integrally formed axially opposite one another thereon along an axis of rotation, a fastening bolt, and a connection portion connected to the guide rail. The connection portion has a connection leg, with a through-opening for the fastening bolt, between two lateral legs having mutually aligned joint grooves for receiving the joint pins of the joint piece, which pivots between the lateral legs and is pivotably mounted in the connection portion. A vehicle window lifter for adjusting a window glass of a motor vehicle is also provided.

A safety cabinet includes an enclosure having a double-walled construction and a pair of doors to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a sequential door-closing system that sequentially closes the doors of the safety cabinet in a predetermined order.

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.

An arrangement includes a rail profile and a running carriage movably mounted relative to the rail profile in the longitudinal direction and to which a sliding door can be fastened. The running carriage has a rolling body, and the rail profile has a running surface extending in the longitudinal direction of the rail profile and supporting the rolling body. The rolling body is displaceable on the running surface transversely to the longitudinal direction of the rail profile. Therefore, the running carriage can be pivoted about a pivot axis extending substantially parallel to the longitudinal direction of the rail profile. The rail profile has a vertical web extending in the longitudinal direction and oriented substantially perpendicularly to the running surface. The running carriage can be pivoted about the pivot axis such that a distance from the vertical web increases under loading by the sliding door.

A guide system for guiding a door wing, in particular a folding-sliding-door, movably supported relative to a furniture carcass. The guide system includes a guide rail having a longitudinal direction, the longitudinal direction of the guide rail extending substantially parallel to a depth direction of the furniture carcass in a mounted condition on the furniture carcass. A carrier is provided for movably supporting the door wing, and the carrier is displaceably supported at least over a region along the guide rail. An abutment is provided for determining an end position of the carrier in the longitudinal direction of the guide rail, and an adjustment device can adjust a position of the abutment. The abutment can be adjusted by the adjustment device in the longitudinal direction relative to the guide rail.

Disclosed embodiments include a mounting apparatus for a sliding security barrier that includes unique security features that ensure the sliding security barrier is secure and does not suffer problems that exist with conventional security doors and windows. The sliding security barrier is configured to be implemented using tracks that are common to conventional sliding patio screen door or windows. Additional security features include a unique striker plate, a lift protector at a corner, adjustable top and/or bottom channel caps, an interlock, and a uniquely shaped lock. These features provide greater security at a lower cost because they use an existing sliding door or window sash and channels but provide a secure attachment that inhibits tampering and removal of the sliding screen barrier.

A rail adjuster for mounting a rail of a window regulator assembly to an adjacent fixed surface of a closure panel of a vehicle, the rail adjuster comprising: a mount body for mounting to the rail, the mount body defining an adjustment axis; an adjustment body coupled to the mount body and also for mounting to the adjacent fixed surface; and an adjuster portion positioned between the adjacent fixed surface and the adjustment body, the adjuster portion providing said coupled by passing through an aperture of the adjustment body in order to engage with the mount body; wherein operation of the adjuster portion causes a change in an initial length of the rail adjuster to an adjusted length by moving the mount body relative to the adjustment body along the adjustment axis.
