Abstract: A fire resistant frame structure for a facade or glass roof, includes a column profile, and a beam profile connectable to the column profile to form a support construction and so positioned relative to the column profile as to form spaces for receiving fire protection glasswork. The column profile and the beam rofile are each made of aluminum and comprised of a supporting core member for receiving static loads, an enclosure surrounding the core member, connecting members joining the core member to the enclosure at formation of a hollow chamber, and adsorbent material received in the hollow chamber and having heat absorbing and hydrophilic properties. The connecting members are formed by bridge members which provide a low heat conductivity to effect a low heat flux from the enclosure to the core member. Thus, crystal water can be released when the adsorbent material is subject to a certain temperature level to thereby cool the metallic framework.

Abstract: A fire resistant frame structure for windows, doors, facades or glass roofs, includes a metallic structural element for connection to at least one other metallic structural element to form a frame. Secured to the outside and/or inside of the frame are slabs of adsorbent material which retain a high water content and exhibit heat absorbing and hydrophilic properties. The slabs of adsorbent material react or are activated at a certain temperature level to release their water content in order to cool the frame.

Abstract: A T-joint comprises a rung having at least one cavity and a lower face. A frame has a first side facing the rung. The frame has a longitudinal groove disposed in the first side and the groove has a floor and a plurality of upper edges, such that there is a gap disposed between the plurality of upper edges and the floor. The frame has at least one T-joint part that extends into the at least one cavity. The at least one T-joint part is fixedly connected to the groove. The lower face of the rung faces the frame and is disposed adjacent to the upper edges of the groove. At least one sealing cushion is disposed in the gap. The at least one sealing cushion is made from an elastic material and is fixedly connected to the frame such that the gap is sealed by the sealing cushion.

Abstract: One stile of the sash in a door or window frame has an elongated channel for an elongated trough-shaped gear case rotatably receiving a first gear in mesh with the toothed rack of a reciprocable carrier in the gear case. A bifurcated end portion of the carrier mounts a second gear which meshes with a fixed rack of the gear case and with an elongated rack which is slidable along and overlies an open side of the gear case. The first gear can be rotated by a handle to move the carrier whereby the second gear rolls along the fixed rack and causes the elongated rack to perform a movement greater than the carrier. The elongated rack is coupled to motion receiving bars in the channel of the stile.

Abstract: An actuating handle arrangement for the actuation of fittings of a window casement or a door leaf includes an actuating handle which is mounted for turning about a turning axis on a housing which is secured to a window casement or door leaf frame. The actuating handle operates a pusher bar fitting which is coupled with an entraining member of a slide which is mounted in the housing for displacement in the longitudinal direction. The slide is provided with a guiding groove, in which there engages an entraining pin of an eccentric which is connected with the actuating handle. In the end positions of the actuating handle which correspond to the closing and the tilting position of the window casement, the line connecting the intersection point of the turning axis and the intersection point of a central axis of the entraining point with an imaginary plane along which the slide moves extends at right angles to the central longitudinal axis of the guiding groove.

Abstract: A corner deviating device for a locking bar brace supported in a casement frame of window or a door has a one-piece housing which is provided in a corner region with a mounting opening for a spring band having drivers at its ends, the mounting opening being closable by an angular cover. One leg of the housing is insertable into a receiving groove of one wing of the casement frame, while the other leg of the housing is fixable on an edge strip of an associated receiving groove of another wing of the frame.

Abstract: An insulating strip for a heat-insulated composite section with two metal rail sections and at least one insulating strip positioned between them and intended for windows, doors, or facades. The insulating strip has a rectangular basic cross-section with anchoring webs along the edge that are accommodated on at least one side in recesses in the metal rail sections. The anchoring webs at at least one end of the insulating strip end at a distance from the face that corresponds to the rectangular basic cross-section.

Abstract: A device for fastening together the parts of a heat-insulated composite section consisting of two metal sections and of at least one insulating rod has knurling rollers that shape exterior groove webs, forces them against the insulating rod, provides them with a knurled strip. The knurling roller has conical, toothed, circumferential surfaces. The bottom land between each pair of teeth parallels the conical circumferential surface. The knurling rollers are mounted in a tensioning mechanism that consists of two annular disks in such a way that it can be displaced along its axis. It can be displaced 0.5 to 1 mm to each side out of an intermediate position. The axial flotation make it possible to compensate for errors in alignment between the knurling roller and the composite section that occur while the groove webs are being shaped as a result of undesirable superimposition of the tolerances of the separate parts. The knurling rollers are mounted in such a way that they cannot rotate on powered shafts.

Abstract: In a glass-metal structure for a front wall or a roof of a building, comprising a metal framework and glass panels, the framework is formed of hollow elongated main frame sections and hollow elongated crossbar frame sections extending transversally of the main frame sections. Cover plates overlapping the edges of the glass panels are screwed by bolts to the frame sections. Each frame section and each cover plate is provided with anchoring grooves receiving sealing strips. Each frame section has gutters for condensed water and grooves for percolating waters. Each crossbar frame section has a main hollow chamber and an additional hollow chamber formed between the gutters of the crossbar frame section.

Abstract: A composite section that the frames of a window or a door are made out of or that are used to construct a facade consist of a plastic rail section and of a metal rail section. The metal rail sections face inward when the composite section is employed to construct a window or a door frame, whereas the plastic rail sections constitute the outer shell. The plastic rail section has anchoring webs with free edges that engage recesses in the metal rail sections. The anchoring webs are secured in the recesses because the outer recess webs and/or inner recess webs conform to the shape of the anchoring webs. The plastic rail sections are angular in cross-section and have outer flanks that in the case of a window or door constitute motion-limiting webs or glass-securing strips. The fittings that connect the casement to the window frame and the fittings that anchor the window frame are attached only to the metal rail sections.
