A lighted roll up door assembly may include a roll up door including interconnected slats movable along tracks, and a lighting element configured to be attached to an exterior side of the roll up door. The lighting element can be mounted so as to direct a substantial portion of the light output toward the roll up door and below a horizontal direction so as to light a portion of the door and an adjacent area below the door at least partially by reflection when the door is in a closed position and so as to light an area on an interior side of the roll up door when the door is in a opened position. The lighting element may be mounted to a fixed or movable member attached to a slat of the roll up door.

The invention relates to a door comprising a door leaf (10) which can be moved between an open position and a closed position and a guide arrangement for guiding the movement of the door leaf along a predefined path between the open position in the closed position, wherein the guide arrangement has at least one guide web (100) which is arranged fixedly with respect to a wall opening, extends at least along a portion of the predetermined path, and has two outer boundary surfaces (102, 104) and at least two guide devices (32, 34) which are fastened to the door leaf (10), wherein a first outer boundary surface (102) of the guide web (100) forms a surface for a first guide device (32) and the second outer boundary surface (104) of the guide web (100) forms a second guide surface (104) for a second guide device (34). Magnetic devices (1000, 1010, 1100) can be arranged on the door leaf and on the guide bar for guiding in a contactless manner.

A barrier system includes a roll-up barrier comprising a plurality of slats hingedly connected, a guide system, and a drive system. Each slat of the plurality of slats includes a central portion having a first thickness, a top portion, and a bottom portion. At least one of the top portion or the bottom portion having a second thickness less than the first thickness. The top portion of each slat overlaps the bottom portion of an adjacent slat forming an overlapping region having the first thickness when the barrier is in a closed configuration. The guide system is configured to guide movement of the roll-up barrier. The drive system configured to transition the roll-up barrier between open and closed configurations along the guide system.

This disclosure presents a safe high speed roll-up door with spiral brackets. To enable a high speed operation, robust spiral brackets having efficient spacing are provided to guide the plurality of sectional slats. Durable and low noise signature rollers are used. A unique assembly configuration of the slats and the tracks guiding the rollers enable quick replacement of each individual roller without disassembling the door. A double-belt counter weight mechanism balances the door and incorporates safety sensors that prevent loosening the belts when the door is jammed. The belts are further adjustable using ratchets such that adjustment for the horizontal balance as well as weight position is made effortless. In all, the high speed roll-up door using sectional slats performs faster and quieter, withstands greater loads, and lasts longer than other existing roll-up doors with spiral brackets.

The present invention relates to a door (10), in particular a spiral door or roller door, having a flexible curtain or having a plurality of profiles articulated with one another. The door comprises: a door leaf (20) movable starting from a closed position in the course of an opening movement into a multilayered wound position, a guide assembly (30) having a spiral-shaped guide path section (32) for guiding the opening movement in the region of the lateral edge (22) of the door leaf (20), and a flexible traction element (40) attached to a section (24) of the door leaf that leads in the course of the opening movement for pulling the door leaf into the multilayered wound position.

The present invention discloses a roller shutter for an automobile, comprising guide slots, a roller shutter, a lock catch assembly locked with the guide slots, a rolling and unrolling assembly, a plurality of groups of pre-positioning installation assemblies and locking assemblies. Compared with the prior art, the roller shutter for an automobile enables the two guide slots to keep parallel through the pre-positioning installation assemblies and the positioning and locking assemblies during the assembling of the roller shutter. Because the switching process of the roller shutter is smoother at the connection between the roller shutter and the guide slots, more labor is saved. A guide turntable enables the roller shutter to slide through frictional force with the slots of the roller shutter, rolling and unrolling become smooth. The lock catch assembly can lock and position the roller shutter at any time, flexibility is strong and freedom is high.

A high-speed stroke-type moving device for an elongate flexible body having at least one supply line. The device has a guideway for guided displacement of the body, having a spiral portion, in which at least part of the body is compactly accommodatable in a plurality of spaced tracks which are not in mutual contact and extend substantially spirally inwards. The invention provides that the body has a line guideway for the at least one supply line. According to the invention, the line guideway here has a first sub-portion which is guided in the spiral portion and an unguided second sub-portion having a first end which is connected at the end to the first sub-portion and a second end which is connected at the end to a rotary feedthrough for the at least one supply line. A corresponding device having an energy chain is furthermore disclosed.
