FIG. 2 is a side elevational view thereof.
FIG. 3 is an end view looking in the direction of arrow 3 of FIG. 2 illustrating details of the concealed hinge.

DESCRIPTION OF THE PREFERRED EMBODIMENT For the purposes of promoting, an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood! that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
Referring now to FIGS. 1 and 2, there is shown a toilet seat ring 21 and a toilet seat lid 20 pivotally mounted atop flange 22 of a conventional toilet. A pair of mounting brackets 23 and 24 are securable toflange 22 and pivotally receive the toilet seat ring and toilet seat lid. Lid 20 is fragmented in area 25 illustrating the ring shaped configuration of the toilet seat. Ring 21 has a main body seat portion 26 which extends generally horizontally having a front end 27 and a rear end 28. End 28 includes an upwardly extending wall 29 (FIG. 6) which forms a cavity30 for concealing mounting brackets 23 and 24. A pair of spaced apart flanges 31 and 32 (FIG. 3) are integrally connected to the toilet seat ring and extend downwardly from wall 29 thereby cooperatively defining cavity 30 with wall 29.
The toilet seat lid 20 includes a main body wall 36 (FIG. 2) which is testable atop ring 21 thereby covering the ring. Wall 36 has a front end 37 and a rear end 38. A pair of walls 39 and 40 (FIG. 3) are connected to end 38 and depend therefrom. Walls 39 and 40 are provided with sockets which bearingly receive respectively hinge pins 33 and 34 thereby allowing the toilet seat lid to be pivotable on the hinge pins. Walls 39 and 40 have mutually facing surfaces with the sockets opening only through the mutually facing surfaces. For example, socket 41 is provided in wall 40 and opens only through surface 42 (FIG. 4) of the wall. The mutually facing surfaces of walls 39 and 40 are parallel and adjacent to the outwardly facing surfaces of flanges 32 and 31. For example, surface 43 (FIG. 3) of flange 31 is immediately adjacent to surface 42 of wall 40. Flanges 31 and 32 have mutually facing surfaces which are parallel and adjacent to brackets 24 and 23. The holes in flanges 31 and 32 open only through the mutually facing surfaces and the outwardly facing surfaces of the flanges. For example, hole 35 (FIG. 6) of flange 31 opens only through surface 43 and surface 44 (FIG. 3). Flanges 31 and 32 which are positioned immediately inward of walls 40 and 39 and immediately outward of brackets 24 and 23 are integrally connected to the toilet seat ring. Pins 33 and 34 project outwardly from the mounting brackets through the flanges and into the sockets of walls 39 and 40. The pins are in coaxial relationship as are the holes in flanges 31 and 32- and the sockets in walls 39 and 40. Both the sockets and the holes are defined by continuous cylindrical surfaces. Both pins have cylindrical cross sections.
It will be obvious from the above description that cavity 46 which is cooperatively formed by portion 45, wall 47 and walls 39 and 40 conceal wall 29 when the lid rests atop the ring. Likewise, recess 30 formed by wall 29 in end 28 of seat 21 conceals the brackets secured to the toilet including the hinge posts.
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention and the scope of the claims are also desired to be protected.
