Abstract
Abstract A water blocking device mainly for the use on the interior of buildings and the like, but also usable outside thereof comprises a triangular-shaped structure in two shapes which may be interlocked to form small dam-like barriers. The primary structure is straight and formed with tongue and groove ends with one tongue being interlockable with the groove of the adjacent section. The second shape being that of a 45° curve again with the tongue and groove interlocking end portions. On the bottom surface of both type sections, recessed disc portions are provided to form in effect a plurality of miniature suction cups. Thus, when two or more of these structures are interlocked together and appropriately fastened to a smooth surface such as provided by a floor of a building, a quickly removable and interchangeable semi-permanent dam structure will be formed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
97 words
A surface water blocking device comprising; a self-supporting longitudinally extending section member having, first means for connection to another such section member in interlocking fashion to present a continuous barrier to the flow of surface water, second means for removably fastening each member to the surface on which they rest in a water-tight semi-permanent fashion, the first means for connecting one section member to another section member includes a tongue and groove type joint, and the second means for removably fastening each section member to the surface includes suction cut type recesses provided in each section member.
Claim 2
Dependent Claim
97 words
A surface water blocking device comprising; a self-supporting longitudinally extending section member having, first means for connection to another such section member in interlocking fashion to present a continuous barrier to the flow of surface water, second means for removably fastening each member to the surface on which they rest in a water-tight semi-permanent fashion, the first means for connecting one section member to another section member includes a tongue and groove type joint, and the second means for removably fastening each section member to the surface includes suction cut type recesses provided in each section member.
Claim 3
Dependent Claim
34 words
The structure as set forth in claim 1, wherein at least one side of the section member is provided with a special shape to increase the holding action of the suction cup type recesses.
Claim 4
Dependent Claim
28 words
The structure as set forth in claim 2, wherein a plurality of section members are provided and connected to form a long continuous surface water blocking dam structure.
Claim 5
Dependent Claim
29 words
The structure as set forth in claim 3, wherein some of the plurality of sections are of curved configuration and others of the section members are of straight configuration.
Claim 6
Dependent Claim
45 words
The structure as set forth in claim 4, wherein some of the curved sections have the tongue and groove interlocking portions reversed with the respective ends thereof in order to form reverse curved blocking sections and at least one part of the over-all blocking dam.
Claim 7
Dependent Claim
140 words
A water blocking device comprising: section means of basic triangular cross-section configuration having tapered sides and a flat bottom and of relatively long length in relationship to the flat bottom of the triangular cross-section, interlocking means at each end of the section means to form a watertight connection with another similar section means in order to complete a water blocking dam structure, and additional fastening and attaching means along the bottom portion of the triangular configured section means for semi-permanently securing each of the section means to the surface upon which they are being used, said section means are straight and other of the section means are of curved configuration, and the additional fastening and attachment means along the bottom surface of the section means include suction cup type devices for positively attaching the section means to the surface structure.
Claim 8
Dependent Claim
140 words
A water blocking device comprising: section means of basic triangular cross-section configuration having tapered sides and a flat bottom and of relatively long length in relationship to the flat bottom of the triangular cross-section, interlocking means at each end of the section means to form a watertight connection with another similar section means in order to complete a water blocking dam structure, and additional fastening and attaching means along the bottom portion of the triangular configured section means for semi-permanently securing each of the section means to the surface upon which they are being used, said section means are straight and other of the section means are of curved configuration, and the additional fastening and attachment means along the bottom surface of the section means include suction cup type devices for positively attaching the section means to the surface structure.
Claim 9
Dependent Claim
56 words
The structure as set forth in claim 6, wherein the interlocking means at each end of the section means includes a tongue and groove type configuration with the tongue portion being provided at one end of a section means and the grooved recess to complement same being provided at the opposite end of the same section.
Claim 10
Dependent Claim
40 words
The structure as set forth in claim 7, wherein the tapered sides of the sections provide means for increasing the holding action of the suction cup type devices on the bottom as the height of the water being blocked increases.
