Abstract
A glazing panel particularly usable for a greenhouse or a skylight has a glass sheet 5 and a synthetic-resin panel 1 formed by inner 3 and outer 2 synthetic-resin plates parallel to but spaced from each other by a plurality of transverse synthetic-resin webs 4 that unitarily inter-connect and space the plates and form between them a plurality of dead-air spaces 8. The inner plate 3 may be bonded to the face of the glass sheet 5 or retained by a frame 9 spaced from the sheet by spacers 12, and the dead-air spaces may be sealed at the periphery of the panel. <IMAGE>
Description
SPECIFICATION
Shatterproof insulating laminate
The present invention relates to a laminate. More particularly this invention concerns a semitransparent glass-type laminate of the shatterproof and insulating type.
The most common type of shatterproof laminate simply comprises a pair of glass sheets sandwiching a synthetic-resin layer that is bonded flatly to the sheets to both sides of it. The layer and both sheets are transparent so that the laminate has the external hardness and appearance of a sheet of solid glass.
Nonetheless if this laminate is cracked or broken any shards or splinters will remain stuck to the syntheticresin layer, thereby holding together and creating no safety hazard.
This system has the disadvantage that such a laminate is an extremely good conductor. Thus in applications such as in a greenhouse it is necessary to provide two such laminates spaced apart in order to create an insulating dead-air space. Furthermore, in the event that such a laminate is impacted with considerable force, although a great deal of small dangerous shards are not produced, nonetheless large pieces presenting dangerous jagged edges are created. What is more, as it is necessary for the two glass sheets sandwiching the synthetic-resin layer to have a certain thickness in order to give adequate strength to the finished product, the prior-art laminate is quite heavy per unit of surface area and is relatively expensive.Yet another disadvantage is that if a so-called obscure glass is desired, that is one which lets all the light pass but which multiply refracts the image to break it up, it is necessary to texture the outer surface of the safety glass, thereby creating an unsmooth surface that becomes dirty quite easily.
It is an object of the present invention to provide an improved laminate.
In this invention there is a laminate having a glass sheet to one flat face of which are secured inner and outer synthetic-resin plates which extend parallel to but are spaced from each other by a plurality of transverse synthetic-resin webs which unitarily interconnect and space the plates and form between them a plurality of dead-air spaces. The plates and sheet are sealed together at their peripheries to close the dead-air spaces off.
According to this invention the sheet and plates are transparent so that the laminate acts as an extremely effective safety glass. The transverse synthetic-resin webs unitarily interconnecting and spacing the plates serve to break up and to refract the light passing through the laminate without appreciably diminishing the overall amount of light that goes through the laminate. The dead-air spaces will obviously impart good insulating properties to the laminate. Thus the laminate according to this invention is ideally usable in applications such as skylights and greenhouses.
If the laminate is subjected to an impact severe enough to break the glass sheet it will remain stuck to the flexible synthetic-resin plates. Thus the laminate according to this invention will be almost completely hailproof. This also makes it ideal for use in a skylight or a greenhouse.
According to further features of this invention the transverse webs, which are integrally formed with the inner and outer synthetic-resin plates, are constituted as parallel web strips extending perpendiocular to the plates and defining parallel passages.
These passages are sealed at their ends to form the laminate into a so-called thermal pane.
In the drawings,
Figure 1 is a partially sectional and partially end view of laminate according to this invention;
Figure 2 is a top view of a laminate according to this invention; and
Figure 3 is a view similar to Figure 1 of another laminate according to this invention.
A laminate according to this invention basically comprises a unitary synthetic-resin panel 1 formed of an outer plate 2, an inner plate 3, and a plurality of parallel transverse web strips 4 defining parallel voids or passages 8, and a glass sheet 5. A bead 6 of silicone extends completely around the peripheries of the panel 1 and glass sheet 5 to seal them together and to close the ends of the passages 8.
The inner plate 3 is secured to the face of the sheet 5 either by a continuous film or adhesive, or spots of adhesive, or a sinusoidal bead of adhesive such as shown at 7 in Figure 2. In this manner the entire assembly is rigid and if the sheet 5 is broken its shards will remain stuck to the panel 1.
It is also possible according to this invention to space the panel 1 from the sheet 5 as shown in
Figure 3 by spacers 12. This entire assembly is then held in a frame 9, with a silicone mastic 10 sealing the periphery of the space 13 between the inner plate 3 and the sheet 5 and another bead 11 securing the panel 1 unto the top edge of the frame 9.
Normally the sheet 5 is of conventional clear glass with a pair of planar shiny faces. The panel 1 is unitarily made of a synthetic-resin such as polymethyl methacrylate, polyvi nyl ch I o ride, or polyethylene. Here a durable polycarbonate is used.
The resultant structure will be substantially lighter than safety glass of equivalent strength and similarly will be substantially lighter than thermal-pane glass of equivalent insulating properties. Light passing through the laminate, according to this invention will, admittedly, be refracted and broken up, yet nonetheless virtually all of the light will pass through the laminate, making it ideal for use in a skylight or in a greenhouse.
The spacers 12 can be either simple rods or buttons holding the panel 1 and glass 5 apart, or can be strips extending parallel to each other or even crossing one another. In any event the dead-air spaces inside the laminate according to the invention are all sealed at their edges or ends. So long as the original manufacturer takes care to ensure that clean air of very low humidity is inside these spaces 8 and 13 before they are sealed off no condensation need be expected.
