Abstract
Abstract A splash guard for the open upper end of a toilet bowl to prevent water or similar liquid material from splashing out of the toilet bowl when unclogging the toilet by the use of a plunger, generally known as a "plumber's helper". The splash guard includes a generally flat plate sufficiently large to cover the open upper end of the toilet bowl and includes a flexible central diaphragm provided with an opening to receive and allow movement of a plunger handle whereby vertical movement of the plunger will not result in water splashing out of the open upper end of the toilet bowl.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
A plunger splash guard for a toilet bowl comprising a generally flexible diaphragm constructed of relatively thin, resilient flexible material, frame means connected with said diaphragm and seal means connected with the diaphragm for sealing engagement with the top surface of the rim of a toilet bowl for forming a closure for the open upper end of the toilet bowl, said diaphragm including a hole formed therein for closely receiving the handle of a plunger when used in unclogging the drain of the toilet bowl to prevent splashing of liquid or similar material from the toilet bowl upwardly and outwardly of the open upper end thereof when the plunger handle is being reciprocated when unclogging the drain.
Claim 2
Dependent Claim
117 words
A plunger splash guard for a toilet bowl comprising a generally flexible diaphragm constructed of relatively thin, resilient flexible material, frame means connected with said diaphragm and seal means connected with the diaphragm for sealing engagement with the top surface of the rim of a toilet bowl for forming a closure for the open upper end of the toilet bowl, said diaphragm including a hole formed therein for closely receiving the handle of a plunger when used in unclogging the drain of the toilet bowl to prevent splashing of liquid or similar material from the toilet bowl upwardly and outwardly of the open upper end thereof when the plunger handle is being reciprocated when unclogging the drain.
Claim 3
Dependent Claim
54 words
The structure as defined in claim 1 wherein said frame means is substantially rigid as compared to the diaphragm with the frame means generally conforming to the dimensional characteristics of the periphery of the rim of the toilet bowl for retaining the diaphragm in overlying relation to the drain area of the toilet bowl.
Claim 4
Dependent Claim
47 words
The structure as defined in claim 2 wherein said hole in the diaphragm is substantially centrally located with respect to the diaphragm and generally in alignment with the drain area of the toilet bowl for positioning the plunger in alignment with the drain from the toilet bowl.
Claim 5
Dependent Claim
71 words
The structure as defined in claim 3 wherein said diaphragm has a periphery extending beyond the inner periphery of the frame means, said inner periphery of the frame means being defined by an enlarged central opening providing a flexure area for the diaphragm with the periphery of the diaphragm extending beyond the periphery of the opening in the frame means and terminating inwardly from the outer periphery of the frame means.
Claim 6
Dependent Claim
103 words
The structure as defined in claim 4 wherein the seal means includes a sealant member extending peripherally along the bottom surface of the frame means with the outer periphery of the sealant member being coincidental to the periphery of the frame means, said sealant member including an inner periphery defining an opening around the periphery of the diaphragm and disposed radially outwardly of the inner periphery of the frame thereby forming an annular area of frame means overlying the diaphragm with that portion of the diaphragm radially outwardly of the inner periphery of the frame means being fixedly secured to the frame means.
Claim 7
Dependent Claim
92 words
In combination with a plunger having a handle by which the plunger can be manipulated when unclogging a toilet bowl drain by reciprocating the handle, a splash guard engaging the rim at the open upper end of a toilet bowl in sealed relation, said splash guard including a flexible diaphragm having a hole closely receiving said handle to enable movement of the handle, said diaphragm including a peripheral frame of more rigid construction than the diaphragm, said frame including resilient seal means on the lower surface for sealing engagement with said rim.
Claim 8
Dependent Claim
92 words
In combination with a plunger having a handle by which the plunger can be manipulated when unclogging a toilet bowl drain by reciprocating the handle, a splash guard engaging the rim at the open upper end of a toilet bowl in sealed relation, said splash guard including a flexible diaphragm having a hole closely receiving said handle to enable movement of the handle, said diaphragm including a peripheral frame of more rigid construction than the diaphragm, said frame including resilient seal means on the lower surface for sealing engagement with said rim.
