Abstract:
A laminated strength-reinforced window assembly comprises a sheet of strength-reinforced transparent material, first and second transparent windowpane sheets. The strength-reinforced sheet has a tensile strength value, an impact resistance value, an environmental resistance value, an upper sealing surface and a lower sealing surface. Each windowpane sheet has a respective tensile strength value, impact resistance value and environmental resistance value. The first sheet is disposed over at least a part of the upper sealing surface and the second sheet is disposed under at least a part of the lower sealing surface. At least one of the tensile strength value, the impact resistance value and the environmental resistance value of the strength-reinforced material is significantly greater than the corresponding value of one of the first and second windowpanes. The windowpane sheets are hermetically bonded to the sheet of strength-reinforced material without non-hermetic adhesives to form a continuous hermetic joint therebetween.
Abstract:
A bullet-proof and/or shatter-proof toughened, laminated glass plate includes a stack of glass sheets. A central ballistic system (BC) of the glass plate has, at its peripheral region corresponding to a reinforcing element (C) of the peripheral ballistic system (BP), one or more reinforcing cladding portions made from a high-strength ballistic material, and integrated in the stack. At least one of the reinforcing cladding portions is integral with the element (C) (i.e., a one-piece construction).
Abstract:
The invention concerns an armoured laminated bullet-proof and/or splinter-proof glazing, comprising on at least part of its periphery, one or several rigid protuberances (3), each of which belonging substantially to a plane parallel to that of the window or its extension, and having a thickness for its being inserted at least partially, temporarily or permanently, in the window aperture rabbet.
Abstract:
A modular vehicle window assembly is provided which has attached thereto interior vehicle accessories. In a preferred embodiment, the window panel assembly includes a window panel disposed within or covering a window opening formed in the vehicle. The window panel may optionally contain a conventional gasket or sealing structure to provide a weather-tight seal in the window opening. Supported on and interconnecting to the interior surface of the window panel are any one of a number of different accessory configurations, including centerline, island, and peninsular overhead consoles providing storage space, overhead lighting, and air conditioning vents for use by the occupants. Other accessories which may be used include an instrument display assembly, a control assembly, a window shade assembly, and a hand-hold assembly. The interior accessories may be interconnected to the window panel by a variety of fasteners which provide the ability to quickly interchange an interior component and/or provide sufficient tensional strength characteristics to suspend the interior accessory from the interior surface of the window panel. Also provided are a perimeter storage and concealment system for providing a finished interior and storage capability about the interior of the window opening. Preferably, the assembly is used in the roof area of the vehicle such that the accessories are supported overhead of the passenger compartment.
Abstract:
The glazing element in accordance with the invention comprises in its simplest form a pane and a textile spacer fabric arranged at the covering surface of the pane. The spacer fabric comprises at least two covering layers, which are connected together by rib fibers extending approximately transversely in relation to the panes. The glazing element in accordance with the invention possesses thermal insulating properties and may be utilized as safety glass, more particularly for roofs or overhead glazing arrangements.
Abstract:
In a transparent laminated window or canopy for aircraft and the like, flexible fabric tape impregnated with a silicone elastomeric adhesive applied against a surface of one of the plies or reinforcements of the window is used to bond at least one of the plies or reinforcements to another element of the laminated window or to a reinforcing frame of an aircraft panel which comprises the laminated window. Such tape is easier to apply during the assembly operation than previously used silicone pastes, thereby reducing the cost of fabricating aircraft panels incorporating said window or canopy without paying any unduly large penalty in adhesion between the elements of the panel.
Abstract:
A laminated glass-plastic glazing unit suitable for aircraft is disclosed. The unit comprises a pair of sheets of rigid transparent material such as glass and an interlayer of thermoplastic material that is susceptible to crack at low temperatures and that has a higher coefficient of thermal expansion than the sheets of rigid transparent material. Electrical resistance material preferably in the form of thin metal wire, is embedded within the interlayer and disposed locally in areas along a pair of opposite marginal edges of the interlayer and electrically energized to heat the interlayer portion adjacent thereto sufficiently to overcome the tendency of the interlayer to pull chips from the marginal portion of one or both of the rigid sheets when the unit is subjected to extremely low temperature conditions in a high-flying aircraft. The electroconductive material is embedded within the interlayer in spaced relation to a transparent electroconductive coating on one of the glass sheets for heating the glazing unit to dissipate mist or frost and is located relative to the thickness of the interlayer in a plane that is closer to the rigid sheet more likely to become damaged when the unit is exposed to the aforesaid low temperature conditions. The interlayer may also include a metal reinforcement frame in heat exchanging relation to the electroconductive material that extends to the edge of the interlayer to conduct heat received from the electroconductive material to the edge of the interlayer, thereby retarding the cooling of the edge of the interlayer to a temperature at which it cracks.
Abstract:
A laminated transparent assembly suitable for use as a windscreen for a high speed vehicle, e.g. an aircraft or railway locomotive, comprises a load bearing sheet of toughened glass having a second sheet of glass laminated thereto by means of an impact resistant interlayer of plastics material, e.g. polyvinylbutyral, and an insert of high tensile strength flexible material which extends around the periphery of the interlayer and which has an inner part embedded in the outer marginal portion of the interlayer in a plane parallel to the surfaces of the interlayer, and an outer part extending outwardly beyond the edges of the interlayer to provide for attachment of the assembly to the structure of the vehicle. The insert is preferably a sheet of fabric material, e.g. a fabric woven from rubber-impregnated glass fibre cords and nylon, with the glass fibre cords substantially perpendicular to the adjacent edges of the assembly, embedded between layers of soft polyvinylbutyral. The outer part of the insert may have a flexible portion adjacent to the edges of the interlayer and an outer marginal portion which is reinforced, e.g. with metal, to render it rigid to provide means for attachment of the assembly to the vehicle structure.
Abstract:
Window panels that have edge portions which are out of desired contour have straps of molded fiber glass reinforced thermosetting resinous material adhered to and overlapping both sides of the panels in marginal areas outside the viewing area and extending outwardly from the edges of the panels providing structural supporting members which are molded to conform to the desired panel edge contour for precise fit with frame members of the supporting structures.
