A holding and opening mechanism for a pivoting element which is mounted to be pivotable relative to a supporting element about a first axle via a joint, with a pivoting arm acting between the pivoting element and the supporting element is provided. The pivoting arm is pivotally mounted about a second axle wherein the free end of the pivoting arm acts on a control surface of a guide element. A torsion spring is provided which acts on the pivoting arm in the direction around the second axle, a fixed part and a part pivotable relative thereto likewise provided, with the one part including the guide element and the other part including the pivoting arm. The pivotable part is adapted to be pivotable relative to the fixed part about the joint and the first axle, the pivotable part is connected to the pivoting arm and the pivoting element and the fixed part is connected to the supporting element, the control surface in cooperation with the torsion spring and the pivoting arm determines the holding and opening force via the pivot angle of the pivoting element.

A system is described and includes a rack for carrying payload disposed in payload bay; a rack extension assembly for affecting linear displacement of the rack between a first position in which the rack is stowed within the payload bay and a second position in which the rack is supported outside the payload bay; a payload actuator system for selectively causing the rack extension assembly to move the rack between the first and second positions; a payload bay door; and a door actuator system for selectively opening and closing the payload bay door.

A sectional folding overhead door assembly that includes a pair of opposite, vertically disposed side supports and guides defining a door opening between them, each of the supports and guides including a first channel and a second channel disposed side-by-side, a door component having a first, second, third and fourth rectangular panel adapted for folding vertical movement along the supports and guides, a folding movement controlling member, each folding movement controlling member having a folding movement controlling member upper end hingeably connected to a respective side edge of the first and third panels, respectively, and a folding movement controlling member lower end hingeably connected to the respective guide plate lower end around a folding movement controlling member hinge axis, and a folding movement guiding channel into which a respective side plate guiding pin of a side plate attached to the second panel extends.

A furniture component and method of manufacturing the same, the furniture component having a wall with at least two opposite side faces and a multitude of front faces. On the wall between the side faces, a takeup space is configured which accommodates a set of fittings for guiding a movable furniture element. The set of fittings includes a multitude of fitting components and can be transferred to at least two positions. The takeup space includes aperture sections in at least two front faces of the wall, where the takeup space is outwardly open. The set of fittings is configured and set up such that during transfer of the set of fittings from the first position to the second position, the set of fittings moves at least in the aperture sections in the at least two front faces.

The invention relates to a holding and opening mechanism for a pivoting element, such as a lid, a cover, a door or the like, which is mounted to be pivotable relative to a supporting element such as a housing, a frame or the like about a first axle via a joint, with a pivoting arm acting between the pivoting element and the supporting element, which arm is pivotally mounted about a second axle that is not the same as the first axle, wherein the free end of the pivoting arm acts, preferably via a roller, on a control surface of a guide element, wherein a torsion spring is provided which acts on the pivoting arm in the direction around the second axle, in order to generate a holding and opening force on the pivoting arm and the control surface, comprising a fixed part and a part pivotable relative thereto, with the one part including the guide element and the other part including the pivoting arm, wherein the pivotable part is adapted to be pivotable relative to the fixed part about the joint and the first axle, the pivotable part is connected to the pivoting arm and the pivoting element and the fixed part is connected to the supporting element, wherein the control surface in cooperation with the torsion spring and the pivoting arm determines the holding and opening force via the pivot angle of the pivoting element. The invention is characterized in that a plurality of pivoting arms, guide elements, joints and fixed and pivotable parts are provided, with the pivoting arms being coupled together by a common torsion spring Spin the second axle.

A sectional folding overhead door assembly comprising a pair of opposite, vertically disposed side support and guide means defining a door opening between them, each guide means including a first channel and a second channel disposed side-by-side, a door component comprising a first, second, third and fourth rectangular panel adapted for folding vertical movement along said support and guide means, the door component further comprises at each side of the first and second panel a folding movement controlling member, each folding movement controlling member having an folding movement controlling member upper end hingeably connected to a respective side edge of the first and third panel, respectively, and a folding movement controlling member lower end hingeably connected to the respective guide plate lower end around a folding movement controlling member hinge axis, each folding movement controlling member further including a folding movement guiding channel into which folding movement guiding channel a respective side plate guiding pin of a side plate attached to the second panel extends.

A single hung window has a window frame, an upper fixed lite of glass secured to the window frame and a movable lower sash secured to the window frame with the lower sash being generally coplanar with the upper fixed lite of glass. Lower sash retention elements secured to opposed jamb portions are operatively associated with the lower sash to facilitate securement of the lower sash in a plurality of positions. A balance system is secured within each jamb and is operatively associated with said lower sash. The lower sash may be structured to receive a screen. The sash may be employed alone without the upper fixed lite of glass.
