## Background
FIELD OF THE INVENTION
The present invention relates to shelves for walls, in particular, shelves installed in wall corners.
BACKGROUND OF THE INVENTION
When installing a shelf in a corner location, such as a shower or bath stall, an installer would typically have to prop up the corner shelf while the corner shelf sets in place, as well as tile around the shelf edges. This process of installing a corner shelf is cumbersome and time-consuming. Moreover, the corner shelf may fall out of place while it is being propped-up. Hence, there is a need for a corner shelf that is more convenient for installing.
The system of the present invention provides an easy and fast means of installing a corner shelf, and an installer does not have to tile around the edges of the corner shelf once it is installed.
Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims.

The present invention would provide for a narrower shelf and biscuit assembly.
In some embodiments, the first anterior edge portion (137) and the second anterior edge portion (147) are convexed. In other embodiments, the first recessed edge portion (136) and the first anterior edge portion (137) form a general bell-shaped curve, and the second recessed edge portion (146) and the second anterior edge portion (147) form a general bell-shaped curve.
In some embodiments, the unit is about 1 inch, 1.5 inches, or 2 inches. In other embodiments, the unit is at least 1 inch, 1.5 inches, or 2 inches. In still other embodiments, the unit is between about 1 to 2.5 inches.
In some embodiments, the shelf base may be rectangular or triangular in shape. In other embodiments, the shelf base may be square in shape. In still other embodiments, the shelf base may be arc shaped. For example, the angle of the arc shape may be 90 degrees. In further embodiments, the shelf base may be in the shape of a quarter-circle. The shape of the shelf base is not limited to the aforementioned shapes, and may be of any desired shape for a corner wall.
In other embodiments, the shelf base may have a linear row of biscuit slots disposed in the first side surface or the second side surface. A distance between each biscuit slot may be 1 unit. The corner location would then have a linear row of biscuit slots disposed on the first wall or second wall. The distance between each biscuit slot may be 1 unit. For example, a row having at least two biscuit slots may be disposed in the first side surface or the second side surface. Therefore, a row having at least two biscuit slots may be disposed in the first wall or second wall. The number of biscuits slots of a row would depend on the size of the shelf that is being mounted. For example, a larger shelf may require at least two biscuit slots per row, or at least three biscuit slots per row, whereas a smaller shelf may require at least one biscuit per row.
In another embodiment, the present invention also features a method of installing a shelf system in a corner location. Any embodiment of the aforementioned corner shelf system may be used for installation. The method comprises providing the a shelf of the present invention. Next, a grinder is used to make biscuit cuts into the corner location where the shelf is to be installed, e.g., the shower wall. Then, the inner portions of the first and second biscuits are inserted into the first and second side surfaces of the shelf base, respectively. The first and second biscuits are inserted in the shelf base such that the recessed edges of the biscuits are proximal to the base corner edge. The outer portions of the biscuits that extend outwardly from the side surfaces of the shelf base can be inserted into the biscuit cuts in the wall. Finally, the biscuits can be sealed with an adhesives to secure the shelf base in place. Non-limiting examples of adhesives include epoxy or silicon.
