Definitions

  • the present invention relates generally to a composite panel, and more particularly to a bulletproof composite window panel.
  • Bulletproof window panels are already known, as is the fact that they can be made as composite panels consisting of a plurality of individual panes.
  • at least one light-transmissive that is opaque or transparent panel of synthetic plastic material such as high-molecular thermoplastic polycarbonate on the basis of aromatic dihydroxide compounds, preferably bisphenylolalkanes, having a thickness of at least 2 mm. is sandwiched between two glass panels.
  • the 1 three panels are then so connected with one another they have limited freedom of sliding movement relative to one another. It is preferred to connect the panels with a binder which remains soft, such as silicone rubber.
  • the synthetic plastic panel must be relatively thick-that is, it must have a thickness on the order of 25 mm.if the composite panel is to be bulletproof. This is evidently a disadvantage, as is the fact that even the use of binders between the panels is not always able to prevent the development of undesirable optical faults in the compmite panel, such as Newtons rings.
  • An additional object of the invention is to provide such a composite panel which is low in weight and which does not interfere with visibility therethrough and does not have optical faults.
  • one feature of my invention resides in the provision of a composite panel, particularly a bulletproof window panel, which includes a pair of coextensive first panels of a first material arranged in two spaced parallel first planes, and at least one additional second panel of a different second material coextensive with the first panels and arranged in a second plane intermediate to the first planes with spacing from both of the first panels.
  • Spacing means is interposed between juxtaposed circumferentially extending marginal portions of the respective panels for maintaining the latter out of contact, and sealing means extends along and in contact with these marginal portions for the purpose of sealing the spaces between the respective panels.
  • first or outer panels be of glass, whereas the inner or second panel be of synthetic plastic material.
  • two or more inner panels of synthetic plastic material may be used. If two inner panels of synthetic plastic material are employed, it is sufiicient if they each have a thickness of 5 mm.
  • each panel is spaced slightly from the panels located at its opposite sides makes it possible for each panel to undergo a slight deformation on impact of a missile, such as a bullet, and this in turn increases significantly the penetration resistance of the novel composite panel according to the present invention.
  • the ability to perform yielding movements in response to impact of a missile is further enhanced by the fact that the individual panels are connected together only at their circumferential marginal portions and that, in accordance with a further feature of the invention, the spacing means which is located between the circumferential marginal portions of juxtaposed panels, engages these marginal portions only with linear contact, or at least with substantially linear contact rather than area contact.
  • sealing means I use is elastic and these measures taken together avoid the development of stresses in the composite panel,.which could result from the fact'that the coefficient of expansion of the synthetic plastic material is a multiple of that of the glass, for instance on the order of eight times the coefficient of expansion of glass.
  • FIG. 1 is a plan view of a composite panel according to the present invention.
  • FIG. 2 is a fragmentary section through the panel of FIG. I, on an enlarged scale.
  • my panel is composed in the particular embodiment illustrated of two outer or first panels 1 and 2 which consist of glass, and of two inner or second panels 3 and 4 which consist of synthetic plastic material.
  • the synthetic plastic material of the panels 3 and 4 is preferably a polycarbonate.
  • each of the panels 1, 2, 3 and 4 is spaced from its neighboring panels to provide a free space 10 between adjacent ones of the panels.
  • This spacing is provided and maintained by the spacing means 5 which preferably, although not necessarily, is configurated in form of elongated tubular members 5, such as drawn aluminum tubes, which in the illustrated embodiment are of substantially semicircular cross section and are located inwardly of the outer edges of the respective panels intermediate the juxtaposed circumferentially extending marginal portions thereof.
  • the spacing means 5 constitutes a closed frame 6 located, as already pointed out, slightly inwardly'of the outer edges of the respective panels 1-4. It will be seen that the spacing means 5 engages the juxtaposed circumferentially extending marginal edge portions of the respective panels which it spaces, only with a linear or substantially linear contact.
  • sealing means of suitable type which in accordance with the present invention is preferably an elastic sealing material 8 which remains elastic at all times, such as silicon rubber.
  • the sealing means 8 provides for a tight connection between adjacent panels.
  • the spaces 10 have in known manner a dry gas circulated therethrough to remove any moisture that may be contained in the spaces 10-, and to prevent the intrusion of moisture thereinto until the spaces 10 can be sealed.
  • the semicircular cross-sectional configuration of the spacing means 5 is not the only configurabetween which it is located, and the sealing means 8 can penetrate into these wedge-shaped spaces and provide for particularly good connection between the panels.
  • the flat surface on each of the spacing means 5, facing the interior of the respective spaces 10, provides for a pleasing appearance.
  • Panels according to my present invention are not only light in weight, but are also simple in construction and therefore relatively inexpensive. Furthermore, their thickness overall is comparatively small while the panels are yet bulletproof. In addition to this, they are and remain clear, that is they are not possessed of optical faults and visibility through these panels cannot be detrimentally influenced, for instance by moisturecontaining air penetrating into the spaces 10. Panels of this type can be used in a great variety of different applications, for instances as partitions in taxicabs between the passengers and the driver to protect the latter from attack, in financial institutions between the teller and the customers, for display windows in jewelry stores, and in similar applications.
  • a composite panel particularly a bulletproof window panel, comprising a pair of coextensive first panels of transparent material arranged in two spaced parallel first planes; at least one second panel of yieldably deflectable light-transmissive polycarbonate material coextensive with said first panels and arranged in a second plane intermediate said first planes, said second panel having a thickness of at least 2 millimeters and being spaced from said first panels by a distance sufficient for each of said panels to undergo a slight deformation on receiving an impact; spacing means interposed between juxtaposed circumferentially extending marginal portions of the respective panels for maintaining the latter spaced at said distance; and sealing means extending along and in contact with said marginal portions for sealing the space between the respective panels.
  • said spacing means comprises elongated spacing members constructed so as to engage the respective juxtaposed marginal portions with at least substantial line contact.
  • a composite panel as defined in claim 7, said additional second panel also being of poly arbon ate material.
