Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
141 words
A device for facilitating sexual intercourse comprising a substantially cylindrical thick-walled hollow body which is made of elastic material and whose one end is open while its other end merges with a rounded portion, the elastic material being very soft and yielding, the interior space of the hollow body being connected with the outside via the open end, and at least one valve connecting the interior space with the outside, the valve being adapted to open when an excess pressure is present in the interior of the hollow body and to close when there is a suction force in the interior of the hollow body, wherein at its closed end the hollow body is provided with an extension, whose front part has a recess which is connected with the distal end of the interior of the hollow body via a duct.
Claim 2
Independent Claim
141 words
A device for facilitating sexual intercourse comprising a substantially cylindrical thick-walled hollow body which is made of elastic material and whose one end is open while its other end merges with a rounded portion, the elastic material being very soft and yielding, the interior space of the hollow body being connected with the outside via the open end, and at least one valve connecting the interior space with the outside, the valve being adapted to open when an excess pressure is present in the interior of the hollow body and to close when there is a suction force in the interior of the hollow body, wherein at its closed end the hollow body is provided with an extension, whose front part has a recess which is connected with the distal end of the interior of the hollow body via a duct.
Claim 3
Dependent Claim
32 words
A device in accordance with claim 1 comprising a valve arranged in the duct and adapted to open when there is an excess pressure in the interior space of the hollow body.
Claim 4
Dependent Claim
34 words
A device in accordance with claim 1, in which the valve comprises a valve housing of elastic material, which is held within the material of the hollow body by means of a dovetail joint.
Claim 5
Dependent Claim
62 words
A device in accordance with claim 3, comprising, on the outside of the valve an elastic substantially cross-shaped holding means, a valve cone holding the holding means and a membrane against which the valve cone presses, the membrane, which is elastic, lying in an opening of the valve and being supported on the inlet side by a shoulder means of the valve.
Claim 6
Independent Claim
179 words
A device for faciliting sexual intercourse comprising: a substantially cylindrical, relatively thick-walled hollow body of soft, resilient, elastic material, one end of which is open, and the other end of which terminates in an externally rounded portion; said body having a channel enclosed within a portion of its cylindrical wall, said channel extending substantially lengthwise along said cylindrical body and connecting the internal hollow within said body at the rounded end and the exterior of said body near its open end, and having a valve in said channel near the exterior end thereof, said valve for opening when excess pressure develops in the hollow body and for closing when a partial vacuum develops within said body; and the inside of the body near its open end includes a constriction, and a frusto-conical surface joining the open end of the body and the smaller constriction therein, and the interior of the hollow body has a lesser diameter, which is maintained for some distance into the interior of the body from the constriction, than the internal diameter near the rounded end.
Claim 7
Independent Claim
179 words
A device for faciliting sexual intercourse comprising: a substantially cylindrical, relatively thick-walled hollow body of soft, resilient, elastic material, one end of which is open, and the other end of which terminates in an externally rounded portion; said body having a channel enclosed within a portion of its cylindrical wall, said channel extending substantially lengthwise along said cylindrical body and connecting the internal hollow within said body at the rounded end and the exterior of said body near its open end, and having a valve in said channel near the exterior end thereof, said valve for opening when excess pressure develops in the hollow body and for closing when a partial vacuum develops within said body; and the inside of the body near its open end includes a constriction, and a frusto-conical surface joining the open end of the body and the smaller constriction therein, and the interior of the hollow body has a lesser diameter, which is maintained for some distance into the interior of the body from the constriction, than the internal diameter near the rounded end.
Claim 8
Dependent Claim
66 words
A device according to claim 5, wherein the hollow body additionally comprises at the end which terminates in a rounded portion, an extension, and the front part of the extended rounded portion has a depression therein and said extension includes a duct connecting the depression with the internal hollow within said body at the end of saiD internal hollow near the rounded end of the body.
Claim 9
Dependent Claim
23 words
A device according to claim 6, additionally comprising a valve located in said duct for opening when excess pressure develops within said body.
Claim 10
Dependent Claim
34 words
A device according to claim 6, wherein at least one of said valves comprises a valve housing of elastic material which is held within the material of the hollow body by a dovetail-like connection.
Claim 11
Dependent Claim
61 words
A device according to claim 8, wherein said valve comprises an elastic cross-shaped mount on the outlet side thereof, a valve cone connected to said mount, an elastic diaphragm lying in the passage opening of the valve and supported on the inlet side by a shoulder of the valve housing with the valve cone contacting the surface of the elastic diaphragm.
Claim 12
Dependent Claim
26 words
A device according to claim 5, wherein the end of the cylindrical body terminating in an externally rounded portion is entirely closed for preventing sexual conception.
Claim 13
Dependent Claim
37 words
A device according to claim 5, wherein the externally rounded portion terminates in a bead-like projection extending substantially radially from the cylindrical body at the junction of said rounded portion and the remainder of said cylindrical body.
Claim 14
Dependent Claim
14 words
A device according to claim 5, additionally comprising means for stimulation of the clitoris.
Claim 15
Dependent Claim
48 words
A device according to claim 5, additionally comprising a tube-like sleeve surrounding the hollow body and slidably mounted thereon, the length of said sleeve being less than the length of said hollow body, and the ends of said sleeve adapted to maintain the sleeve on the hollow body.
Claim 16
Dependent Claim
19 words
A device according to claim 13, wherein the space between the hollow body and the sleeve contains a liquid.
Claim 17
Dependent Claim
19 words
A device according to claim 13, wherein the space between the hollow body and the sleeve contains a powder.
