Modular curb assembly of pre-cast pre-finished components
Kind Code:
A1


Abstract:
A modular curb assembly of pre-cast pre-finished components forming a base for supporting sidewalls of a shower stall or other enclosure attached to a floor. The curb is made from a plurality of pre-cast pre-finished components of substantially uniform shaped cross section joined in end to end relationship to each other and attached to a floor in a predetermined contour around the perimeter of the enclosure. The components may be straight, curved or in the shape of angular corners and are cast in various configurations which provide a choice of different end angles so that the contour of the curb can be varied depending upon which different combination of component configurations are used in any particular curb design. The pre-cast pre-finished components of this invention are made from a cast polymer composite material similar to or like Solid Surface or Cultured Marble, including the group of granite, onyx, alabaster or the like, as well as cement based, or concrete gypsum cement, composite materials which form a ready to use waterproof outer surface requiring no additional coating or layer added thereto. The walls may be of glass block, plate glass or other materials.

Description:

FIELD OF THE INVENTION

This invention relates to a modular curb assembly forming the base of a wall of glass block, plate glass or other material. More specifically the pre-cast components are made from cultured marble or other materials which form a finished surface when cast and support the sidewalls of shower stalls or other enclosures.

BACKGROUND OF THE INVENTION

The use of curbs is well known in the construction of water containment enclosures such as showers, bathtubs, saunas and hot tubs. Curbs may also be used as a base for supporting walls of glass block, plate glass or other materials which form enclosures or function as divider walls.

U.S. Pat. No. 5,092,002 describes a shower base having a threshold formed by long plastic members over a 2×4 lumber base.

U.S. Pat. No. 6,735,793 describes a prefabricated block for constructing a water containment curb for use with showers, bathtubs and the like.

US Patent Application Publication No. US 2003/0089059 A1 shows a lattice frame placed over horizontal 2×4s and a waterproof liner to form a curb upon which ceramic tiles are laid.

Various other patents show components for constructing water retaining curbs, however such components need to be cut on the ends to obtain the necessary angles which when the components are assembled will provide the desired contour in the curb. Furthermore many of the prior components need to be covered with tile in order to have a finished surface. In addition, none of the curbs of the above patents are designed to accept specific glass block shapes and configurations

SUMMARY OF THE INVENTION

This invention as claimed is a modular curb assembly of pre-cast pre-finished components forming a base for supporting sidewalls of an enclosure attached to a floor which is made from a plurality of pre-cast pre-finished components of substantially uniform shaped cross section joined in end to end relationship to each other and attached to a floor in a predetermined contour around the perimeter of the enclosure, the pre-cast pre-finished components cast in various configurations which provide a choice of different end angles so that the contour of the curb can be varied depending upon which different combination of component configurations are used in any particular curb design, each of the pre-cast pre-finished components being cast from a material which forms a ready to use waterproof outer surface requiring no additional coating or layer added thereto.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the details of the invention, FIG. 1 shows fragmentary perspective view of a shower stall assembly 20 having a modular curb assembly 22 mounted on a floor or base surface and has water collection tray 26 at the bottom of the shower stall with a drain as shown in FIG. 2. Glass block walls 24 are mounted on top of the curb assembly 22. The curb 22 is constructed from a series of straight intermediate components 28 and corner component 30 forming a 90° angle between two of the straight components 28. An end cap 32 is showing covering an end of a component 28.

A shower stall can be made using existing walls 34 as part of the enclosure or it can be made free standing with all the walls made from glass block mounted on the curb assembly 22.

FIG. 2 shows a fragmentary perspective view of a curb assembly 22 with straight components 28, and two 45° corner components 36. An elastomeric sheet 38 covers the floor area beneath the shower stall. The sheet 38 is sealed to a flange 40 of the components 28 and 36. A sloping concrete filler 40 is placed on top of the sheet 38 and slopes toward a drain 42. A plastic cover sheet 44 is placed on top of the filler 40 and is in sealing engagement with the drain 42 and forms a water collection tray 46.

It may also be seen that ceramic tile can also be used instead of the plastic sheet 44. Also the water collection tray 46 can be made as one piece instead of with a filler and a cover sheet.

Referring now to FIG. 3, a shower stall assembly 20a is shown having a curb assembly 22a with straight components 28, 90° corner components 30, 45° corner components, 36, and 90° corner components 30a and 30b. A single row of glass block 48 is placed on top of the curb assembly 22a. It may be secured in place by adhesive or mortar. Further similar layers can be added to make a complete series of walls for the shower stall. An end cap 32 is placed on each open end of any of the curb components.

FIGS. 4 through 15 show individual components which make up the curb assembly when combined in to form the desired contour for each enclosure.

FIG. 4 shows the straight intermediate component 28 which was previously shown on previous figures.

FIG. 5 shows a 90° angle arcuate component 29 to be used with a PC arque 90 degree component of glass block.

FIG. 6 through 8 shows 90° angle corner components 30, 30a, and 30b. These components are identical except the distance between the ends is longer on some than others.

FIGS. 9 and 10 both show a 45° angle corner component 36 except that FIG. 10 shows a curb connector bracket 50 attached to each end of the angle component 36. The connectors are attached to each pair of adjacent ends by adhesive or other suitable means.

FIG. 11 shows a curb connector bracket 50 before it is attached to an end of one of the components.

FIG. 12 shows a curb connector bracket 52 for connecting an end of a curb component 28a to a side of another curb component 28b as shown in FIG. 13.

FIG. 14 shows the back of an end cap 32 and FIG. 15 shows the front of the end cap 32 which may be used on any open ends of the curb components as previously described.

FIG. 16 is a plan view showing a shower stall 20a similar to that shown in FIG. 3 but listing the different kinds of commercially available glass block that can be accommodated by the various configurations of curb components shown in previous figures. Other corner configurations besides those shown in the drawing can also be made to accommodate other corner angles besides 90° and 45°.

For example angles such as 22½°, 62½°, 135°, 112½° or other angles can be accommodated.

In making an assembly of a shower curb, the desired combination of intermediate and corner components are selected and attached to the floor to form the desired contour. A water collection tray 26 as previously described is placed on the floor area of the shower stall and the curb is sealingly assembled around the tray. The rows of glass block are then built up to the desired height from the curb.

It should be understood that while glass block has been shown as the materiel for constructing the walls, other material such as plastic or plate glass or other materials can also be attached to the curb of this invention.

The pre-cast pre-finished components of this invention are shown as made from a cast polymer composite material similar to or like Solid Surface or Cultured Marble, including the group of granite, onyx, alabaster or the like, as well as cement based, or concrete gypsum cement, composite materials. Other materials can also be used so long as it provides components of sufficient strength to support the type of walls selected and provides a waterproof finish that is attractive and suitable for use when installed without the need for any additional surface finish.

These and other variations may be made without departing from the scope of the invention.
