With reference, to the accompanying drawings, the present design includes an inner surface portion and an outer surface portion. The inner surface portion has a forward opening, a floor portion, side wall portions, a back wall portion, and a ceiling portion. The upper portion of the back wall portion has a vertically and longitudinally orientated middle portion which is forwardly concave. A surface at the top of this middle portion slopes upward and forward from the concave surface to the vertically planer surfaces located to either side of the middle portion. Below the middle portion a forwardly convex surface extends upward, forward, an inward form the planer of the vertically planer surfaces to the horizontal bottom edge at the bottom of the middle portion which partially defines a horizontal planer surface extending rearward to the concave surface of the middle portion. Laterals back wall surface extend laterally and forward from the middle portion to the side wall portion. The upper portions of the side wall portions each have a vertical planer surface. The ceiling portion has a horizontal planer surface. The upper portions of the back wall portion and the side wall portions, and the ceiling portion, merge with each other at inwardly concave surfaces.The lower portion of the back wall portion has a vertical planer surface from which an forwardly convex surface extends upward and forward towards the center and having a forwardly convex upper edge, from which a horizontal planer surface extends rearward. Form this horizontal planer surface a shallow ledge extends inward around the inner periphery of the inner surface portion.The floor portion has a forward horizontal surface which extends rearward to a laterally extending edge from which a surface extends downward to a horizontal surface which slopes slightly downward to a circular opening near the center of the floor portion. This slightly sloping horizontal surface merges with the surrounding vertical surfaces at an inwardly concave surface.From the forward opening an inner surface extends downward to the floor portion, upward and rearward to the ceiling portion, and rearward and laterally outward to the side wall portions.The outer surface portion includes a forward vertical planer surface defined by the forward opening and an outer rectangular edge. The rest of the outer surface portion generally takes on the same shape as the inner surface portion.Drawings of the design are included wherein:Fig. 1 is a left, top front perspective view of a plumbing enclosure embodying our new design;Fig. 2 is a front elevational view thereof;Fig. 3 is a right side elevational view, the left side elevational view being a mirror image of the right side shown;Fig. 4 is a top plan view thereof;Fig. 5 is a cross-sectional view thereof taken along line 23-23 of Fig. 2; andFig. 6 is a cross-sectional view thereof taken along 24-24 of Fig. 2. |
