Invention title: MODULAR EXTRUDED COUNTERTOPS The following statement is a full description of this invention, including the best method of performing it known to us: dxbm M01 105091500 000000 21.09.1999 MODULAR EXTRUDED COUNTERTOPS BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to countertops and methods for manufacturing the countertops. More particularly, the invention relates to extruded modular countertops and methods for manufacturing the extruded countertops.

2. Description of the Prior Art Decorative countertops are found in household kitchens and bathrooms throughout the world and play a major role in the appearance of the kitchen or S 10 bathroom. Countertops are commonly made from decorative laminates, solid surface materials, granite and marble.

It is often desirable, however, to mix materials and decorative patterns when preparing a countertop. This is sometimes accomplished by utilizing different S-materials on opposite sides of an appliance, or on opposite sides of the kitchen or bathroom. Similarly, individuals may employ differing back splashes and top surfaces or front edges and top surfaces to achieve a desired aesthetic effect.

Unfortunately, however, individuals wishing to mix countertop components in this manner must choose among a variety of countertop materials which are not specifically designed for use together or they must special order custom made countertops designed to meet their specific needs. Neither of these options are appealing to most individuals desiring to update their kitchen or bathroom with a new countertop. These options are also not appealing to builders wishing to meet the specific needs of consumers, while also maintaining a reasonable overhead in the construction of new homes.

Specifically, special order countertops are expensive and beyond the budgets of many homeowners. As to using disparate countertop components to achieve a desired result, since the countertop components are often not designed for use together, the individual installing the countertop must often make time consuming changes in the countertop components before they will fit together.

Neither option is acceptable, and an alternative is required providing consumers with the choices they desire and deserve. The present invention provides such an alternative.

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a modular countertop permitting individuals to mix countertop components and achieve a desired aesthetic effect. The modular countertop includes at least a first longitudinal 10 extending countertop component and a second longitudinally extending countertop S. component. The first countertop component includes a first connecting member and S°the second countertop component includes a second connecting member, wherein the first connecting member and the second meting member selectively and securely couple the first and second countertop components together when the first and 15 second connecting members are properly joined.

It is also an object of the present invention to provide a modular countertop wherein the countertop components may be a top surface, a back splash and/or a front edge.

S• It is another object of the present invention to provide a modular countertop wherein the countertop components are extruded.

It is a further object of the present invention to provide a modular countertop wherein the connecting members are respectively integrally formed with the first and second countertop components.

It is also an object of the present invention to provide a modular countertop wherein the connecting members snap fit to selectively and securely couple the countertop components together.

It is another object of the present invention to provide a modular countertop 3 wherein the first connecting member is a tongue and second connecting member is a groove, and the tongue fits within the groove to selectively and securely couple the first and second countertop components together.

It is a further object of the present invention to provide a modular countertop including a pin which securely couples the tongue and groove together.

It is also an object of the present invention to provide a modular countertop wherein the first connecting member includes an elongated shaft with a bulbous end and the second connecting member includes a cam lock which locks the first connecting member and the first countertop component in position.

10 It is another object of the present invention to provide a method for assembling a countertop. The method is achieved by manufacturing at least two countertop components chosen from the group consisting of a top surface, a back splash and a front edge, wherein each of the at least two countertop components include selectively connecting members securely coupling the countertop components S 15 together when the connecting members are properly joined. The connecting members are then joined to securely couple the countertop components and the countertop components are installed a predetermined location.
