Another outdoor kitchen system is disclosed in U.S. Pat. No. 8,147,009, filed Dec. 1, 2009, and issued Apr. 3, 2012, to H. Joe Rider. It discloses a component system for constructing the framework for cabinets used for building an outdoor kitchen. The components system consists of specially designed brackets used in conjunction with lightweight concrete side end panels to construct the forms for the cabinets. The brackets have channels that attach to the corner edges of the concrete side end panels and hold the side end panels in place so that the top edges of the panels are accessible for attachment of back splashes and back bars. Brackets with more than one channel have support rods connecting their channels and holding them in spaced apart arrangement. Once the forms are constructed, their exterior surfaces can be finished in a variety of ways. The counter tops, wiring, plumbing, appliances and doors for the cabinets can then be installed to complete the cabinets and kitchen.

Another outdoor kitchen is by Walt tools, www.walttools.com, using a modular precast panel system. It makes panels from concrete that are secured together to form interlocking panels that are 32″ tall and 4″ deep and made using a poly-concrete hybrid design and weigh a fraction of solid concrete. Panels interlock both in linear and perpendicular fashion. Panels include interlocking tabs on each side with holes extending through the tabs for receiving locking pin or bars. The manufacturing of the panel is disclosed in the video at https://www.walttools.com/resources/diy-outdoor-kitchen-class-with-concrete-countertop-solutions/.

Stone Age Manufacturing, https://stoneagemanufacturing.com/, markets an outdoor kitchen and claims its “lightweight, glass fiber reinforced concrete panel and galvanized steel bracket system creates infinitely configurable kitchen island layouts that assemble in minutes, yet deliver strength and durability far superior to other construction methods, providing a strong, stable foundation for appliances and kitchen equipment, that may be covered with any masonry-compatible finish.” The panels can be adhered to each other end to end and rely on metal brackets. “Kits consist of 2” thick lightweight concrete panels of varying width, that are glued together using landscape block adhesive and galvanized steel brackets that further bond the panels for additional security. Upper brackets assist in easily maintaining a uniform depth and keeping the cabinets square during assembly.” “Adhesive beads” are used to secure panels and the metal brackets to each other.

Concrete Components, https://concretecomponents.com/index.html, markets Stone Kitchen Modular Outdoor kitchens. The kitchens are made of precast concrete interlocking components including vertical posts that have vertical longitudinal notches that hold panel components in place. The components are made of solid reinforced concrete blended with certain admixtures and reprocessed Styrofoam for weight reduction. The outer surface of the panels may be embossed to simulate stone. The vertical posts and panels are bonded together with TypeN mortar.

BRIEF SUMMARY OF THE INVENTION

The invention comprises an outdoor cabinet of varying sizes and configurations made from only combinations of two light weight thin cement based composite panels, cross beams and backsplash units and thin set or other similar adhesive. The panels have interlocking edges and interlock and fit together and are held together by thin set or other similar adhesive. The cross beams can be added to the upper edge to support a kitchen countertop and lower edges of the panels where needed. Back splash units may be added to the upper edges of the rear panel to support a countertop. Holes are cut into the panels and countertops to accommodate metal outdoor cabinet inserts, drawer inserts, refrigerators, cooking grills and the like. A decorative finish such as plaster, tile, brick or other weather resistance decorative finish is typically provided for the outside of the cabinets. The use of only four prefabricated components allow various size and configured cabinets to be quickly assembled on site with substantial saving in time and labor.

The advantages of the invention include speed of construction, impervious to weather, full masonry construction, customizable to different standard sizes and shapes.

An advantage of having a different side end panel is that is does not leave notches at the top or bottom and at mid top which are used by the cross beams. Also it makes it easier for panels to fit better at sides. The configuration of the front and rear panels make its section 30 inches wide.

The cross beams that interlock with the panels allow the panels to be thinner so they weigh less for transport and are easier to handle and move during installation. The countertops that are concrete or stone are heavy and the wide crossbeams support the countertops and give them a solid feel. The cross beams maintain the 30 inch width when they are in place and panels are abutted together end to end. The cross beams keep the structure in line and true vertical during construction until the thin set fully hardens.

The configuration of the panels and cross beams allow one to construct an outdoor kitchen in a matter of an hour with thin set. The kitchen can be customized to many shapes and configurations.

The cabinets are a full masonry product that be quickly constructed, does not rust, and is usable near bodies of salt water.

Polymer enriched thin set or other adhesive fillers are used to adhere the parts together and make the cabinet rigid. The thin set or adhesive could also fill any cracks where the components are joined together. At this point the joints are at least partial visit without any finish on the outer surfaces of the panel. The panels 10 on the back run the opposite direction as the panels on the front. The different edge configurations 31 and 32 on side end panels 30 allows it to be places at either side by flipping its side edges. The tabs or teeth 23 and 23 are cut off with a masonry saw. Cross beams 50 are shown in all of the notches formed on the upper edges of the front and rear panels. However, upper cross beams may be left off in areas where a kitchen component such as a grill is installed where the cross beams would be. Similarly a lower cross beam may be left out when a kitchen component such as a refrigerator is installed. Any notches not filled with a cross beam would be filled in with thin set or similar filler. Openings may be cut out in the front panels 10 to accommodate cabinet components such as metal cabinet inserts, metal drawer inserts, metal door inserts, cooking grills, refrigerators, wine coolers and icemakers. Components such as sinks, and faucets can me mounted in countertops that are added to the finished cabinets. Suitable electrical wiring and plumbing can be positioned inside the cabinet. Each of the backsplash panels 50 includes a rectangular electrical box cut out 73. Any unused cut outs 73 would be filled with thin set during assembly of the panels.

FIG. 8 shows the rear of a base cabinet during construction. This illustrates the flipping of the panel sides for the rear cabinet assembly during installation. FIG. 9 shows an installer placing the components in position during assembly of an “L” shaped kitchen. This is two separate cabinets that are abutted against each other.

Polymer enriched thin set or other adhesive filler is placed in all joints to adhere the components together and form a rigid cabinet. The thin set would fill any empty notches and gaps in the interconnected tabs or teeth and notches and would be troweled smooth with the outer surfaces of the panels.

FIG. 10 shows a finished cabinet without any countertop and kitchen components installed or any backsplash. A decorative finish such as plaster, tile, brick or other weather resistant decorative finish is typically provided for the outside of the cabinets. The cabinets include openings 80 and 81 cut into the front panels 10 with a masonry saw for receiving metal kitchen components. The connection lines are no longer visible with an outer surface finish such as plaster or stucco that is troweled onto the outer surface to give it a finished look.

FIG. 11 shows a finished cabinet with a decorative finish and with a countertop 84 and kitchen components 82 and 83 installed without any backsplash. The cabinets openings 80 and 81 in the front panels 10 have metal kitchen components such as drawer unit 82 mounted in opening 80 and door cabinet unit 83 mounted in opening 81. The connection lines are hidden by an outer surface finish such as plaster or stucco that is troweled onto the outer surface to give it a finished look.

FIG. 12 shows a finished cabinet with a decorative finish with a countertop 84 and kitchen components 82 and 83 installed without any backsplash. The cabinet openings 86 and 88 in the front panels 10 have metal kitchen components such as refrigerator 85 mounted in opening 86 and drawer and door cabinet combination unit 87 mounted in opening 88. A cooking grill 89 is mounted cutouts in the countertop 84 and front panel. A natural gas line and electric connection for the grill may be mounted inside the cabinet. An access door may be mounted in the end or rear of the cabinet for placing an LP gas tank inside the cabinet to power the cooking grill 89. The connection lines are hidden by an outer surface finish such as Stucco Stone, or Tile, that is troweled onto the outer surface to give it a finished look.

The panels, backsplash, and cross beams are made of a lightweight, fiber reinforced, thin cement-based composite. Materials used include Portland cement, sand, and fired clay gravel. Shredded fiberglass or other suitable lightweight reinforcement is added to the mix to act as a strengthener and helps prevent cracking from shrinkage, and transport. Dry polymer is also added to the mix to improve adhesion, flexural strength, tensile strength, and freeze/thaw durability. It also reduces permeability, the intrusion of chlorides, salts, and carbon dioxide. Cement hardener is included to increase compression strength. An example is Nyad G which reacts with the crystalline structure of cement to make it hard. Fly ash is added to decrease curing time and increase heat tolerance. Calcium Sulfate Aluminate or CSA may be added primarily for high heat refractory applications, moderate acid-resistance, high-early-strength and quick-setting mixtures, and as part of the expansive component in shrinkage-compensating cements. Cement hardener increases compression strength of panels. Fired clay gravel is lighter, harder, and thermally stable. The added curing agent decreases curing time and increases heat tolerance.

The panels are cast in molds. Each mold has a rigid outer mold of plastic material and an inner flexible mold. The rigid outer mold keeps the shape of the panels flat without bowing or sagging and the inner mold allows the mold to flex and release from the panel after curing. The notches for the beam are about three inches square in cross section. You may fill in unused beam notches with a block and thin set Each panel is thirty inches wide and thirty-five inches high and one and one-half inches thick. The height with an added countertop is designed to approximate the standard kitchen cabinet height. When a “L” or other shaped cabinet is desired one simply builds two cabinets and abuts them against each other as shown in FIG. 9.
