Abstract: An espagnolette-lock for use on a leaf within a sash-frame having a casing, an operating rod movable between a locked position and an unlocked position, a controller for actuating the operating rod, a springy element for automatically restoring the operating rod to the locked position, a manual controller for moving the operating rod to the unlocked position and for restoring the springy element to a compressed condition, a locking mechanism for maintaining the operating rod in the unlocked position during an opening of the leaf from the sash-frame, and an unlocking mechanism for releasing the locking mechanism when the leaf is closed into the sash-frame so as to return the operating rod to the locked position. The locking mechanism includes a toggle joint having a first rod and a second rod connected together by a fulcrum. The first rod is connected through a hinged joint to the operating rod. The second rod is connected through a hinged joint to the casing.

Abstract: A hinging fitting for joining a sash-frame to a leaf in which the hinging fitting has a fixed support adapted to be attached to the sash-frame, a movable support adapted to be attached to the leaf, a spindle pivotally affixed on the fixed support and a bushing affixed to the movable support. The spindle is subdivided into at least two spindle lengths. At least one of the spindle lengths is offset from a longitudinal axis of another spindle length. The bushing has a bore formed by at least two elongated holes arranged substantially in an extension of each other. The elongated holes receive respectively the spindle lengths.

Abstract: An apparatus having a sliding leaf, a slide member, at least two rail wheels mounted on respective spindles, a mounting mechanism affixed to the slide member and extending in a direction perpendicular to a plane of the sliding leaf, and fixing lugs affixed to and extending outwardly from a lower edge of the slide member at respective ends of the slide member. The slide member is a casing having two sets of recesses. The recesses in each set of recesses increase in height from a center of the casing to a respective end of the casing. The recesses in each set extend from the lower edge of the casing towards an upper wall of casing. The spindles have ends received by respective recesses of the two sets of recesses. The recesses have a narrowing so as to lock onto a respective end of the spindles. The casing is secured in a slot formed in a lower edge of the sliding leaf. The mounting mechanism enables the casing to rock within the slot.

Abstract: A hanging fitting for a door, window or the like having a fixed support inserted on the sash-frame and on which is installed a spindle for inserting a movable support fixed on the leaf of the door, window or the like into a bushing. The spindle is pivotally installed, by an eccenter, on the fixed support. The bushing corresponding with the movable support is covering a sleeve. This sleeve has an eccentered bore for receiving the spindle of the fixed support.
