Abstract:
Apparatus for opening aligned sliding leaves of furniture, wherein the or each sliding leaf comprises, at its upper part, an upper track for receiving a first roller having a vertical axis and connected to a movable part of a slide guide fixedly secured to or integral with the furniture. The movable part is movable in a direction substantially perpendicular to the plane of the leaf and is provided with an engagement member, such as a pin, coupled with a first pulley connected, by means of an inextensible, flexible element, to a second pulley in a lower part of the furniture. The second pulley is supported by a horizontal shaft extending across the width of the door leaf and is provided at its ends with a pair of arms, acting upon lateral trolleys supported by pairs of rollers sliding in guides rigidly secured to the furniture. The trolleys carry a U-section member in which run horizontal-axis second rollers and vertical-axis third rollers, rigidly connected to the door leaf by means of a lower support member. On the lower member are also mounted fourth rollers arranged, when the leaf is moved perpendicular to the plane and in a direction away from the furniture, to cooperate with a horizontal lower track mounted parallel to the front surface of the furniture.
Abstract:
A door coordinator for pairs of swinging doors comprising a pair of arms on a common hub pivotally mounted in a bracket on the door frame, a longer arm adapted to move vertically into and out of the path of an active door and a shorter arm provided with a cam surface supplemented or constituted by a roller so located that the inactive door engages the cam surface and/or the roller for controlling the vertical movement of the shorter arm relative to the inactive door and the simultaneous vertical movement of the longer arm into and out of the path of the active door.

Abstract:
Mechanism for unfolding series-connected, accordionlike folded structural elements, particularly for use in supporting large surface solar cells. The several sections to be folded and unfolded are connected by hinge structure including a torsion-bar tensioned when said parts are in a selected on of folded or unfolded conditions. In addition, force transmission means are arranged between panels which rotate in the same direction during movement in response to the urging of said tensioned torsion bars. These force transmission devices ensure that said arm sections will unfold (or fold) at predetermined ratios with respect to each other, regardless of the effectiveness of successive individual torsion bars and will further ensure predeterminable response by said arm sections, even if certain of said torsion bars are out of action. If desired, a power means can be applied to operate through said force transmission means for restoring the arm sections against the force of said torsion bars to said selected condition.
Abstract:
A vehicle includes at least one tailgate defining a door plane, wherein the tailgate is attached to the vehicle chassis in a jointed fashion by at least one multiple hinge having at least three pivot axes offset from one another and at least two pairs of pivotally connected hinge arms, of which a first hinge arm is pivotally connected to the vehicle chassis and a second hinge arm is pivotally connected to the tailgate. The multiple hinge is associated with a drivetrain controlling the motion of the hinge arms in the pivot axes. The door plane is moved along a predetermined motion path when the tailgate travels from a closed position, in which the tailgate spans a closed plane, to an open position, in which the tailgate spans an opening plane. The motion path of the door plane includes rotary and translational components, and the closed plane forms an angle to the opening plane in the range from 70° to 110°, preferably about 90°.
Abstract:
A sliding device (13), guided on the ceiling (3) or under the floor (7) of a cabinet (1) with a rail element (19), which allows a sliding door (15) to be synchronously pulled away from the closet (1) in a parallel manner and then slid. In order to also guide the lower edge of the sliding door (15), the motion of the sliding door can be transmitted from the upper edge of the sliding door to the lower edge by a transmission shaft. No cavities or guide grooves have to be formed on the cabinet (1) or the floor (7), ceiling (9), side walls (3), or partition wall (5) thereof.
