Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 259 words
A bathroom space expander for adaption to a conventional toilet tank having a cover, comprising; a first member defining a generally rectangular surface sized and shaped to fit compatibly with the toilet tank cover, the first member having a main generally rectangular surface with top and bottom surfaces and front, side and rear edges, a second member swingable in relation to the first member, defining a generally rectangular surface approximately equal to but slightly greater than first member's main surface, the second member having a top and bottom surfaces with a front edge and overhanging side and rear edges defining overhanging side and rear walls, means for swingably connecting the members to a first closed stored position and a second operational position, means for supporting the second member in the operational position, means for securely but removably connecting the first member to the toilet tank cover; said side edges each comprising an expandable side having a predetermined length and including a pair of inwardly extending elongated longitudinal members having a first portion within the second member main surface and including an upwardly extending top means, and a second exposed portion outside the main surface having a second end fixed connected to the side edge and, the second member having a pair of longitudinally extending recesses adapted for slidable connection with the side elongated members and the recess having an upper open space sized and adapted for limiting slidable connection with the stop means to allow for limited slidable movement of the expandable side with respect to the second member.
Claim 2
Dependent Claim 259 words
A bathroom space expander for adaption to a conventional toilet tank having a cover, comprising; a first member defining a generally rectangular surface sized and shaped to fit compatibly with the toilet tank cover, the first member having a main generally rectangular surface with top and bottom surfaces and front, side and rear edges, a second member swingable in relation to the first member, defining a generally rectangular surface approximately equal to but slightly greater than first member's main surface, the second member having a top and bottom surfaces with a front edge and overhanging side and rear edges defining overhanging side and rear walls, means for swingably connecting the members to a first closed stored position and a second operational position, means for supporting the second member in the operational position, means for securely but removably connecting the first member to the toilet tank cover; said side edges each comprising an expandable side having a predetermined length and including a pair of inwardly extending elongated longitudinal members having a first portion within the second member main surface and including an upwardly extending top means, and a second exposed portion outside the main surface having a second end fixed connected to the side edge and, the second member having a pair of longitudinally extending recesses adapted for slidable connection with the side elongated members and the recess having an upper open space sized and adapted for limiting slidable connection with the stop means to allow for limited slidable movement of the expandable side with respect to the second member.
Claim 3
Dependent Claim 41 words
The device as set forth in claim 1 wherein at least one of the side edges of the second member comprises an expandable side, and wherein the second member main surface includes stop means for limiting extention of the side edge.
Claim 4
Dependent Claim 61 words
The device as set forth in claim 1 wherein the means for securely fastening the first member to the toilet tank comprises the first member top surface having a recess centrally located between the front and rear edges, and a strap means with locking means extending the length of the recess and wrapped around the toilet tank in a vertical plane.
Claim 5
Dependent Claim 111 words
The device as set forth in claim 3 wherein the means for supporting the second member in the second operational position comprises: a second member bottom surface with a recess centrally formed therethrough, a first tubular member having a predetermined length including a first end for reception in said recess and including a single diametric through hole between said first end and a second end; a second tubular member having a plurality of spaced apart through holes along a main central length thereof, and keeper means for selective engagement through any one of said plurality of holes in said second tubular member and said single hole in said first tubular member.
Claim 6
Dependent Claim 35 words
The device as set forth in claim 4 wherein the toilet includes a closed seat cover and said second tubular member includes a terminal end defining an enlarged foot resting upon the toilet seat cover.
Claim 7
Dependent Claim 26 words
