ADJUSTABLE GLASS WINDSCREEN SYSTEM

Abstract

An adjustable glass windscreen system including an elongate shoe secured atop a supporting surface with inner and outer vertical shoe walls journaled into a baseplate to define a track. A glass adjustment block is seated within the track of the shoe, likewise a three-walled open-top framing member defining a track. A glass panel is seated in the glass adjustment block. The width of the adjustment block is less than the track of the shoe to allow lateral adjustment. Buffer pads line the inside top edges of the opposing inner and outer shoe walls. Adjustment bolts are threaded through the inner and outer shoe walls and penetrate the bottom base of the glass adjustment block for back-and-forth adjustment thereof, and hence the glass panel seated therein. This cantilevers the glass panel about the buffer pads and amplifies the adjustment upward to the upper edge of the glass panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] Reference will now be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0017] The present invention generally is an adjustable frameless glass windscreen system capable of supporting very heavy glass panels side-by-side in an elongate shoe, and which simplifies installation and allows adjustment of the glass panels for proper alignment. With combined reference to FIGS. 1-2, the adjustable frameless glass windscreen system 2 generally comprises a windscreen glass panel 10, fixedly anchored in an adjustable shoe 20. The dimensions of the glass panel 10 may vary as a matter of design choice and may be single or double pane glass panels of clear safety glass, preferably double-tempered-safety glass.

[0018] The adjustable shoe 20 comprises inner and outer parallel-spaced shoe walls 22 journaled into grooves 29 in baseplate 24, preferably by tongue-and-groove fit as shown to define a elongate shoe with interior track for seating a glass adjustment block 26. The inner and outer shoe walls 22 and baseplate 24 may be, for example, 1 ¼” stainless steel panels of dimensions shown in FIG. 2. The glass adjustment block 26 is carried within the interior track of the adjustable shoe 20 between inner and outer shoe walls 22 and atop baseplate 24. The glass adjustment block 26 is a unitary framing member that likewise comprises inner and outer parallel-spaced walls that define a elongate shoe with interior track for seating glass panel 10, all within the larger track of adjustable shoe 20. The glass adjustment block 26 may be formed of aluminum, for example, with spaced vertical walls for cradling the glass panel 10 and a reinforced bottom base to support the weight. The bottom base may be hollow as seen in FIG. 1 to conserve weight. The glass adjustment block 26 preferably rides atop a nylon strip 28 for material separation and to reduce friction, preferably a 1/16″ thick nylon strip. Similarly, the windscreen glass panel 10 rides atop a nylon strip 25 for material separation, preferably a 1/16″ thick nylon strip, and the strip 25 is seated inside a framing buffer 27, preferably formed of Delrin™ plastic or the like. Framing buffer 27 comprises a sock inserted endwise onto glass panel 10 with opposing foldover flaps that fold together about the end of glass panel 10. Alternatively, the framing buffer 27 may be a single U-shaped strip or two opposing L-shaped strips seated into and conforming to the interior track of the adjustable shoe 20. The windscreen glass panel 10 is centered within the adjustable shoe 20 and upwardly supported by a pair of buffer pads 23, preferably deformable silicon strips running along the inside top edges of the opposing inner and outer shoe walls 22. Importantly the width of the adjustable shoe 20 is slightly less than the spacing between opposing inner and outer shoe walls 22 leaving a lateral adjustment clearance.

[0019] As seen in FIGS. 1-4 a series of laterally-spaced adjustment bolts 30 penetrate both inner and outer shoe walls 22 of adjustable shoe 20 as well as the bottom base of glass adjustment block 26. The adjustment bolts 30 are installed into the opposing inner and outer shoe walls 22 and carry the glass adjustment block 26 there between, such that clockwise and counterclockwise turning of adjustment bolts 30, respectively, shifts the glass adjustment block 26 laterally back and forth between opposing inner and outer shoe walls, allowing a small degree of back-and-forth adjustment capability of glass panel 10 within inner and outer shoe walls 22.

[0020] As seen in FIGS. 1-2 the adjustment can be accomplished from the inside of the inner shoe wall 22, e.g., from the inside of the windscreen assembly 2, with the securement bolts 32 safely anchoring the glass panel 10 inside shoe 2 to prevent falling out. This fine adjustment causes the panels 10 to cantilever about buffer pads 23, so that the degree of adjustment is amplified at the top of the glass panels 10 to account for more substantial misalignments along the top edges. When the top edges are aligned the glass adjustment block 26 is locked in place by a double-nut outside the outer shoe wall 22. In addition to adjustment bolts 30, a series of laterally-spaced glass securement bolts 32 penetrate both inner and outer shoe walls 22 as well as the glass panels 10 approximately midway between adjustment bolts 30 and buffer pads 23. The heads of securement bolts 32 may be countersunk as shown in FIG. 2, and securement bolts 32 safely anchor the glass panel 10 inside shoe 20 and prevent falling out.

[0021] The base plate(s) 24 is/are secured to a supporting structure such as a floor. For example, the FIG. 2 shows a plurality of separate base plates 24 each clamped within screw-clamps 21 secured to an underlying floor, albeit the manner of attaching each shoe 20 to the underlying platform, flooring or surface may vary as a matter of design choice.

[0022] In practice, installation or assembly of a glass windscreen system 2 according to the present invention starts by securing a baseplate 24 with pre-machined grooves 29 to an underlying platform, flooring or other supporting surface. The inner and outer shoe walls 22 are inserted onto baseplate 24 with tongue-and-groove fit and are welded thereto at three points marked ‘weld” in FIG. 2. Nylon strip 28 is inserted for material separation and to reduce friction, and glass adjustment block 26 is inserted in the track of the adjustable shoe 20 between inner and outer shoe walls 22 bearing atop strip 28 which in turn sits atop baseplate 24. The three-walled open-top framing buffer 27 is inserted into shoe 20. Nylon strip 25 is adhered along the end of glass panel 10, and framing buffer 27 is inserted endwise onto glass panel 10 and opposing foldover flaps are folded overtop strip 25 about the end of glass panel 10.

[0023] As seen in FIG. 5 the windscreen glass panel 10 is brought to bear by a forklift of the like and is inserted into framing buffer 27. Buffer pads 23 are inserted, and the windscreen glass panel 10 is centered within the adjustable shoe 20 by buffer pads 23. The laterally-spaced adjustment bolts 30 are inserted loosely through both inner and outer shoe walls 22 as well as the bottom base of glass adjustment block 26, and securement bolts 32 are likewise loosely installed through both inner and outer shoe walls 22 as well as the glass panels 10 approximately midway between adjustment bolts 30 and buffer pads 23. Finally, the adjustment bolts 30 are adjusted to position the glass adjustment block 26 such that the upper edges of the glass panels 10 are perfectly aligned. Again, all the foregoing work including the adjustment can be accomplished from the inside of the windscreen assembly 2, with the securement bolts 32 safely anchoring the glass panel 10 inside shoe 20 to prevent falling out. Given proper alignment the double-nut adjustment bolts 30 and the adjustment bolts 30 are locked in place.

[0024] It should now be apparent that the above-described system differentiates itself from the industry as a mechanically installed glass windscreen system. It is easier, quicker and safer to install, uses no volatile or combustible epoxies or grout, and is easier to replace in the event of breakage.

[0025] The foregoing disclosure of embodiments of the present invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many variations and modifications of the embodiments described herein will be obvious to one of ordinary skill in the art in light of the above disclosure. The scope of the invention is to be defined only by the claims, and by their equivalents.
