Aluminum h~s been deemod to be a logical choice for a sliding door sill application. Aluminum has been thought to have the mo~t significant strength Çor thia application.
Stronger materials would, of course, be more desirable.
Even aside from the strength issue, however, aluminum does have certain drawbacks. ~ecause of its inherent metallic properties, aluminum has a relatively high coefficient of thermal conductivity. When used in a sliding door sill application, aluminum can conduct heat within the building in which the door is installed to the outside. Thi8 i8 a particularly acute problem in geographic locations where Winters are very cold. In extreme temperature condition~, the temperature gradient between the lnside and outside of a building is quite extreme.
The 301ution proposed when aluminum is used has been to provide a thermal break in order to inhibit thermal conduction. Doing this, however, has translated to high manufacturing costs.
It is to these dictates of the prior art and the problems discussed above that the present invention is directed. It is a composition for a sliding door sill which overcomes the problem~ of the prior art, taking into account the desirable dictates for such a product. J
Summary of the Invention The present invention is a door sill having a particular CompOsitiOn, The sill includes a core which defines a form.
The form i8 maae from spun glass fibers which are treated with a polyester resin. The form thus formed is, in turn, coated with an ultraviolet stable cladding.
In one embodiment of the invention, the core form includes a plurality of vertically-oriented spun gla~s fiber panel~.
The vertically-oriented panels are, in turn, integrated by a plurality of interconnecting panels.
In certain embodiments of the invention, the form can include an unsupported cantilevered portion. Such a portlon, it -~ ' ~ ' , 20~9~04 would be intonded, would exte~d outwardly from a building in which thc 5ill is installed. Becauso of the strength properties afforded to the sill, the cantilevered portion could, in fact, be unsupported.
ln the preferred embodiment, the core form would include glass fibers oriented both in lineal rows and random mats. The form thus constructed would provide flexing strength during vertical load over the length of the sill. The random mat would contribute strength against bending in the vertical plane. As a result, the need for a sill nose support would be eliminated.
The preferred embodiment al90 envisionB employment of an ultraviolet stable sheathing. It is felt that an L~XAN
sheathing would be optimum 9ince such a material i8 not only ultraviolet stable, but it i8 also resistent to impact and abrasion.
Other claddings are, however, contemplated. Other appropriate claddings would, further, include the characteristics of a polycarbonate.
The present invention is thus an improved sill composition and construction. More specific features and advantages obtained in view of those features will become apparent wlth reference to the DETAILED DESCRIPTION OF THE INVENTION, appended claims, and accompanying drawing figures.
Brief Description of the Drawinq The figure is an end perspective view of a door sill constructed in accordance with the present invention.
2059~0~
Detailed DeHcription of the Invention ~ eferring now ~ the drawing wherein like reference numerals denote likè elements throughout the several views, the figure illustrate~ a door sill 10 composed in accordance with the pre3ent inventio~. While the overall qill 10 will be described in order to provide the general background and environment in which the present invention functions, it will be understood that t~e specific focUs of the invention 18 the sill structure itself.~
The figure illustrates a 3ill 10 in pogition on a block 12 of a building in which a sliding door a~Yembly, of which the sill is a part, i9 installed. The sill assembly 14 is seated on the block 12 with a cantilevered portion 16 of the 8111 10 extending outwardly from the block 12. A baseboard 18 i9 ln engagement with a generally vertically-extendlng inner panel 20 of the 9ill 10.
The overall sill 10 supports an extruslon 22 which mounts a flxed door panel 24. The door panel 24 is secured to the extruslon 22 by means of a block 26 which is received wlthin a channel 28 for~ed within the lower edge 20 of the fixed door panel 24.
A sliding door panel 32 is mounted to a track 34 for longitudinal movement therealong between open and closed dispositions. A pile seal is 26 engaged by the botto~ edge 38 of the sliding door panel 32 to in~ulate, when the door panel 32 is in a clo3ed disposition, the inside of the building in which the door 14 is mounted, from the exterior. Additionally, a weather seal strip 40 is mounted to the track 34 along which the sliding door panel 32 moves to 3eal along the bottom edge 38 of the sliding door panel 32 when that panel 32 i9 in its closed di 5pO9 i tion.
The flgure al~o illustrates a ~liding screen door 42 mounted to a track 44 extending upwardly from a cantilevered portion 16 of the sill structure 10. In fact, the screen door 2059~0~
42 i~, typically, suspended by an upper rail thereof ~not shown) from an upper track (not shown). The lower rail 46 of the screen door panel 42 interface3 with the lower track 34 merely for alignment purposes and to inhibit the passage of mud, snow, ice, etc.
As seen in the figure, the sill structure 10 comprises two components, a core 48 and a cladding 50. The core 48 primarily functions to provide structural integrity, rigidity, and strength to the sill 10. The cladding 50 functions primarily to present a surface 52 exposed to the elements and which is protective against those elements. Typically, the cladding 50 is impact and abrasion resistant. Further, it is ultra-violet stable in view of the fact that the sill 10 is usUally exposed to solar radiation.
The core 48 in accordance with the present invention is formed from spun glAss fibers, Those fiber~ are treated with a resin binder. Shape is given to the core 48 by manufacturing it through a proces known a~ "pulltrusion". The process is similar to extrUsion, but the thrust of the force is applied to draw the item through the die from a side of the die after the item has been formed. This i9 a corollary to a standard extrusion proce~s.
i The core 48 comprises a form which includes a plurality of generally vertically-oriented panels 54 which provide support in a vertical plane. The generally vertically-oriented panels 54 are interconnected by a series of transverse panels 56, the core 48 thereby being provided with form and shape.
The core 48 includes a generally horizontalIy-disposed cantilever portion 58. The core 48 cantilever portion 58 serves as a foundation for the overall cantilver portion 16 of the sill 10.
In the preferred embodiment of the invention, the core 48 includes glass fibers which are oriented both in lineal rows and random mats. A core 80 constructed provides flexing strength during vertical load over the length of the sill 10.
The fibers formed into a random mat function to contribute strength again~t bending in the vertical plane. That i8, they provide strength against torqua forcos applied, for example, to the cantilever portion 16 of the 8ill 10. secause of the random fiber matting, the cantilever portion 16 of the sill 10 need not be 9upported.
The sill further includes a cladding 50 which coat3 the core 48. It is important that the cladding 50 provide ultraviolet 5tability 80 that chemical breaXdown does not occur. Further, the cladding S0 should be resistant to both impact and abrasion. Typically, any material having characteristics of a polycarbonate could appropriately function as the material for the cladding 50. It has been found, however, that LEXAN i8 particularly appropriate to function for thi9 purpose. It wili b0 understood, however, that other metals can, additionally, be appropriately used as the cladding material.
As seen in the figure, the inner surface 60 of the cladding 50 generally conforms to a shape defined by various panels 56 of the core 48. The cladding 50 can, thereby, be fitted closely over the core ~8 and be made 3ubstantially an integral structure.
Numerous characteristics and advantages of the invention have been set forth in the foregoing description. It will be understood, of course, that this disclosure is, in many respects, only illustrative. Changes can be made in details, particularly in matters of shape, size, and arrangement of parts without exceeding the scope of the invention. The invention's scope is defined in the language in which the appended claims are expres~ed.
Stronger materials would, of course, be more desirable.
