A rail system comprises: a guide rail; a plurality of stationary electromagnets mounted in the guide rail; and a carriage having a plurality of wheels configured to travel along the guide rail. The wheels are magnets. Movement of the carriage along the guide rail is brought about by a fluctuating magnetic field generated by the stationary electromagnets acting on the wheels.

A door apparatus for closing an access opening and to a parking apparatus equipped therewith. The door apparatus has two vertically aligned guide rails and an inner and an outer door element which are each movably mounted in/on a vertically aligned inner or outer guide of the guide rails. In a closed position, the inner door element is arranged in a first region of the access opening which is situated lower than a second region in which the outer door element is arranged. In an open position, the inner and the outer door element are arranged in a third region of the access opening which is situated higher than the first and the second region. Furthermore, the door apparatus has a locking element and a coupling element.

A window regulator includes a carrier plate, a guide rail, an ascending-side wire and a descending-side wire, a driving portion, and a turnaround portion. The driving portion includes a rotating drum, a reducer, and a driving motor including a yoke portion that is arranged to be adjacent to one side of the reducer in an orthogonal direction orthogonal to the ascending/descending direction. The guide rail is arranged so as to in the orthogonal direction overlap only the ascending-side wire fed out from a first wire feeding-out position at the one side of the rotating drum in the orthogonal direction toward the turnaround portion between the ascending-side wire and the descending-side wire fed out from a second wire feeding-out position at an other side of the rotating drum in the orthogonal direction toward the carrier plate.

A pivoting cursor for a frameless window. A pivoting cursor for a frameless window of a vehicle door, including: a main body portion; a pivoting plate pivotally secured to the main body portion for pivotal movement about an axis; a clamping plate; a seal; and a threaded adjuster for pivoting the pivoting plate with respect to the main body portion.

In an example an overhead door track is provided. The overhead door track includes a vertical track section having an opening to receive a roller of a panel of an overhead door and to guide movement of the roller within the opening and a single solid polymer based vibration isolator coupled to the vertical track section to reduce vibration of the vertical track section caused by movement of the roller within the opening.

A window regulator assembly in a vehicle includes a glass lift plate assembly for moving a window glass up and down along the guide rail. The glass lift plate assembly includes a slider base, a glass holder configured to receive and hold the window glass, and an attachment bracket placed on the glass holder to securely hold the window glass. The glass holder includes an inboard part and an outboard part, and is connected to the slider base by an adjustment member, which is configured to adjust a top edge of the window glass. Further, the window glass is placed between the inboard part and the outboard part of the glass holder and also fixedly held by an attachment fastener. The inboard part of the glass holder slidably moves relative to the outboard part of the glass holder by the rotational movement of the adjustment member.

An example cable tension device is provided. The cable tension device includes a bracket, an arm, and a spring. The arm is rotatably coupled to the bracket and comprises a roller bar to receive a cable of an overhead door. The spring is coupled to the arm. The spring is under a load to cause the arm to rotate away from the bracket to maintain a tension on the cable.

The invention relates to a safety device for a lifting gate (1), in particular for a fast-running lifting gate (1) having a gate leaf (3) movable up and down and guided along both lateral gate opening edges in frames (10), a free leading edge (12) of the gate leaf (3) being assigned, at a distance (D) below the leading edge (12), to a photoelectric barrier (LS) which travels with the movement of the gate leaf (3), wherein the distance (D) can be reduced in a lower end region of a travel path of the gate leaf (3), and wherein at least a transmitting and/or a receiving unit and/or an opposite reflector unit of the photoelectric barrier (LS) is guided and/or arranged within a frame body (11) of the frames (10).

Disclosed is a bottom bracket assembly for a sectional door. Roller wheels engage with tracks along the sides of the doorway to support the door and guide it to move up and down or open and close the doorway. A lift cable connected with lift engagements may be provided to provide an upward bias to the motion of the door to offset the weight of the door. The roller wheels are supported by the bottom bracket assemblies connected at bottom portions of the edge stiles of the door. Each bottom bracket assembly has a bottom bracket fastened to the edge stile and a roller carrier that supports roller wheel. The connection between the roller carrier and the bottom bracket is adjustable to allow the wheel of the roller to be adjusted to a position outward of the edge of the door so that portions of the door, such as a lift bracket connected with the lift cable, do not interfere with the track.

In example implementations, an end cap for a panel of a vertically stacking panel door is provided. The end cap includes a body to be coupled to an end of a panel of a vertically stacking panel door, a first track wheel coupled to the body, a second track wheel coupled to the body, and a vertical stability roller coupled to the body, wherein the first track wheel, the second track wheel, and the vertical stability roller are arranged along a vertical line, wherein the first track wheel is located vertically above the second track wheel and the vertical stability roller is located between the first track wheel and the second track wheel.
