  • Patent number: 5307597
    Abstract: An improved WATER DEFLECTOR is fitted into a glazing pocket of the vertical frame member so as to fully extend between the opposed marginal faces and be coplanar with the opposed marginal faces of the vertical frame member. When a horizontal frame member is assembled with the vertical frame member, the water deflector and the opposed marginal faces of the vertical frame member fully seal off the hollow horizontal frame member, the water deflector never interfering with the assembling operation.

  • Patent number: 5235790
    Abstract: An arrangement for attaching a window board to a transom which comprises a transom having at least one groove formed in the inner end face thereof so as to open towards the indoor side; a horizontally extending cover attachment to which the window board is attached, the cover attachment extending in parallel to the transom; and a plurality of connecting members adapted to be engaged within said groove so as to fixedly secure the cover attachment to the inner end face of the transom. Between the inner end face of the transom and the cover attachment, a heat insulation material is interposed.

  • Patent number: 5095672
    Abstract: In a windowsill, when a sill attachment is pushed downwardly by the weight of a window pane, a pair of vertical plates of a sill member are pulled inwardly by engagement of downward hooks of a horizontal plate with upward hooks of vertical plates, thereby keeping the vertical plates from being deformed outwardly. Therefore, no gap would be formed between the vertical plates and side muntins, keeping rain water from penetrating into the windowsill.

  • Patent number: 4715152
    Abstract: A fixed sash window assembly has a generally rectangular frame holding a pane or panel of glass or other material and installed in an opening in an enclosing wall of a building. The frame includes a sill of extruded metal or rigid plastic material interally comprising a substantially horizontal web having legs depending therefrom to be mounted directly on a window base on the foundation of the building, and exterior and interior flanges extending upwardly from the exterior and interior ends of the web. The exterior flange has its top end portion held against the panel via an exterior sealing strip. A series of drain holes are formed in the web, just interiorly of the exterior flange, for draining the water that may flow through the exterior sealing strip. One of the depending legs of the web, disposed most exteriorly, has a horizontal ledge extending exteriorly therefrom beyond the window base into underlying relation to the drain holes in the web.

  • Patent number: 4662136
    Abstract: A curtain wall assembly composed of horizontal rows of prefabricated spandrel units mounted to respective floor systems of a building, and horizontal rows of prefabricated window units arranged alternately with and connected to the rows of spandrel units so as to enclose the open spaces between the floor systems. Each of the spandrel units and window units comprises a panel or panels and a generally rectangular frame supporting the panel or panels. Each spandrel unit further has an interior reinforcing frame through which it is coupled to the floor system. For firmly holding the window units against forces normal to the plane of the curtain wall assembly, a reinforcing stud is arranged vertically between any two adjoining window units and rigidly coupled to their opposed side frame members.

  • Patent number: 4662135
    Abstract: A device is disclosed for use in mounting an array of standardized curtain wall units to the floor structure of a building. A clevis to be affixed to each curtain wall unit rigidly carries a crosspiece of circular cross section extending parallel to the plane of the curtain wall unit. The crosspiece is to be slidably engaged in an upwardly open notch in a bracket secured to the floor structure, for both longitudinal and angular displacement relative to the bracket. Preferably, each curtain wall unit is to be coupled to the floor structure by two vertically spaced pairs of such mounting devices, with each pair of devices horizontally spaced from each other. The mounting devices allow the horizontal displacement of the curtain wall units relative to the floor structure and can absorb forces acting on the curtain wall units in a direction normal to their plane.

  • Patent number: 4662145
    Abstract: A curtain wall assembly composed of horizontal rows of standardized spandrel units mounted to respective floor systems of a building, and horizontal rows of standardized window units arranged alternately with and connected to the rows of spandrel units so as to enclose the spaces between the floor systems. No direct connection of the window units to the floor systems is required. Preferably, for firmly holding the window units against forces normal to the plane of the curtain wall assembly, a reinforcing stud is arranged vertically between any two adjoining window units and rigidly coupled to their opposed side frame members. Each reinforcing stud has its opposite ends anchored respectively to the reinforcing frames of the spandrel units underlying, and to those of the spandrel units overlying, the two window units between which the reinforcing stud lies.

  • Patent number: 4614069
    Abstract: A curtain wall assembly in the form of an array of standardized curtain wall units. In its simplest form, each curtain wall unit comprises a panel or pane of glass or like material, and a generally rectangular frame supporting the panel. The panel has its top and bottom edge portions engaged respectively in gaps in the top and bottom members of the frame, whereas the opposite lateral edge portions of the panel are arranged exteriorly of the side frame members and secured thereto by a relatively rigid adhesive. The panels of the horizontally adjoining curtain wall units are secured edgewise to each other by a relatively elastic adhesive. Thus, viewed from the exterior side of the curtain wall assembly, the side frame members are concealed behind the panels for the enhancement of an aesthetic appeal of the complete curtain wall assembly. In the embodiment disclosed herein, the array of curtain wall units takes the form of vertically alternating rows of spandrel units and window units.
