Abstract: A swing closure element (1), comprising: —a fixed structure (10) rigidly constrainable to an opening (11) of a door or window or the like, —a first movable wing (20) constrained to said fixed structure (10) by a first hinge constraint (21) so as to be pivotable about a first rotation axis (Z1), according to a predetermined opening rotation direction (W1), —a second movable wing (30) constrained to said first wing by said second hinge constraint (31) so as to be pivotable with respect to the first wing (20) about a second rotation axis (Z2), the first and the second wing (20, 30) being movable between a first closed configuration wherein they are coplanarly arranged to close the opening (11) and a second open configuration, —an articulated, quadrilateral mechanism (50, 50?) connected to the fixed structure (10) and to the second wing (30) comprising at least one stiffening member (61, 61?, 62, 62?) pivotably constrained to said first wing (20) and to a movable member (53, 53?) of said mechanism (50, 50?) conne

Abstract: A multi-panel, folding closure for a closet or recess has one panel suppod on an upright by a mechanism which permits that panel to move horizontally with respect to the upright for practically its entire width, thus permitting the closure to be stowed entirely within the recess when the closure is open.

Abstract: The boot closure described herein includes a case housing a rotatable shaft pon which are wound straps for drawing front and rear halves of the boot upper together. The closure includes a lever connected through a pair of ratchets to the shaft, so that the straps may be tightened by moving the lever back and forth. The ratchet system may be disengaged by lifting the lever, when removal of the boots is desired.

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.
