The invention relates to a vertical sliding element including an element frame and a sash which can be moved in the vertical direction relative to the element frame. In the closed position of the sash, one fitting chamber each is formed in the intermediate spaces which are laterally limited by mutually facing side faces of the sash and the element frame. Each fitting chamber is provided with a guide rail and guide elements guided in the guide rail. The sash is connected to the guide elements via a scissors' arrangement having a plurality of parking scissors. The scissors arrangement is designed for parallel parking of the sash in a partially open position, in which the sash is positioned in front of an opening in the element frame, seen in the horizontal direction, and wherein the guide elements are designed to move the sash parked in parallel in the vertical direction by moving the guide elements in the guide rails.

A first portion and a second portion cooperate to define an opening. Guide structures are in engagement with bracket assemblies so that the bracket assemblies are movable with respect to the guide structures to allow movement of a panel between a closed position and an open position. A stabilizer engages the panel in the open position. In some implementations, the panel may be flush relative to the first portion and/or the second portion in the closed position.

A flat-type ventilation door-window structure includes a frame (1), a first movable sash (2) and a second movable sash (3). The first movable sash (2) and/or the second movable sash (3) can slide up and down in an opening (11) of the frame (1). A first guide device (300) and a second guide device (400) being respectively provided between the first movable sash (2) or the second movable sash (3) and the frame (1). The first guide device (300) and the second guide device (400) can guide the first movable sash (2) or the second movable sash (3) to change the sliding path. The flat-type ventilation door-window structure can block outdoor sound, rain and air, and improve sound insulation, water tightness and air tightness.

In example implementations, a vertically stacking panel door system is provided. The vertically stacking panel door system includes a horizontal door guide, a panel interface zone, a vertical door guide, a plurality of panels to move from a horizontally stacked position in the horizontal door guide to a vertically stacked position in the vertical door guide, a counterbalance system comprising a motor to move the plurality of panels, and a sensor to detect a gap between two adjacent panels of the plurality of panels as the plurality of panels are moved from the horizontally stacked position to the vertically stacked position, wherein the sensor is to transmit a signal to the motor when the gap is detected.

A garage door roller assembly includes at least one track and a first panel and a second panel that are movable along the at least one track. The first panel and the second panel are connected by a hinge. The first panel and the second panel each have a first end portion including a planar surface, a recess defined in the planar surface, and a rail extending from a trough of the recess, the rail having a height that is less than a depth of the recess. A channel member is secured to the rail of the first panel. The channel member extends beyond the planar surface of the first panel and is configured to receive the rail of the second panel.

A means for opening tailgates of vehicles having a split tailgate with a lower door section and an upper door section. The upper door section would essential comprise the rear glass and mounting means of the upper door section to the vehicle. Further, it includes a pair of side guide tracks in the outer frame about the rear glass or panel. The lower door section includes at least four rollers for moving in the guide tracks. A locking and lifting handle in the lower door section releases the lower door to move vertically into the guide tracts. An upper detent or similar device would hold the lower door section on the outside of the upper door section when pushed to the upper extent. When the handle is release, the lower section would be locked to the upper door section.
