Abstract
Abstract A floating pool cover structure for use in protecting swimming pools including a plurality of at least three angularly spaced legs having height adjusting means provided therein, a plurality of flotation blocks each of which adjustably receives a leg therein, a cable connected to each leg above its associated flotation block, said cable serving the dual purpose of maintaining the height adjustment of each leg and also in maintaining the spacing between the plurality of flotation blocks and a top assembly having sockets in which to receive the top of the spaced legs. A plurality of support lines extend from the top assembly to the pool edge and sufficient cover support lines are employed to fully support a top cover which extends from the top assembly and over the pool edge to prevent the entrance of water or debris into the pool during all periods of use.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
169 words
In a floating pool cover structure for protecting a swimming pool having enclosing sidewalls and water retained within the sidewalls, the combination of A. a plurality of flotation members of buoyant material, 1. said flotation members floating upon the surface of the water, 2. said flotation members each having a top surface; B. a support leg associated with each said flotation member, 1. said support legs each being of elongate, rigid construction and having a top and a bottom; C. support means to support the tops of the support legs above the surface of the water; D. top assembly means receiving and securing the tops of the support legs; E. a plurality of cover support lines extending from the top assembly means to the sidewalls of the pool; and F. a waterproof cover carried by the assembly means and the cover support lines, 1. said cover extending over the top assembly means and the sidewalls of the pool to prevent the entrance of foreign material into the said water.
Claim 2
Dependent Claim

In a floating pool cover structure for protecting a swimming pool having enclosing sidewalls and water retained within the sidewalls, the combination of A. a plurality of flotation members of buoyant material, 1. said flotation members floating upon the surface of the water, 2. said flotation members each having a top surface; B. a support leg associated with each said flotation member, 1. said support legs each being of elongate, rigid construction and having a top and a bottom; C. support means to support the tops of the support legs above the surface of the water; D. top assembly means receiving and securing the tops of the support legs; E. a plurality of cover support lines extending from the top assembly means to the sidewalls of the pool; and F. a waterproof cover carried by the assembly means and the cover support lines, 1. said cover extending over the top assembly means and the sidewalls of the pool to prevent the entrance of foreign material into the said water.
Claim 3
Dependent Claim
29 words
The invention of claim 1 wherein each support leg is provided with longitudinal adjustment means to permit longitudinal position adjustment of each leg relative to its associated flotation member.
Claim 4
Dependent Claim
18 words
said flotation members each having a top surface; B. a support leg associated with each said flotation member,
Claim 5
Dependent Claim
18 words
said flotation members each having a top surface; B. a support leg associated with each said flotation member,
Claim 6
Dependent Claim
27 words
The invention of claim 2 wherein each flotation member is provided with an opening and wherein the associated support leg is adjustably positioned in the said opening.
Claim 7
Dependent Claim
27 words
The invention of claim 3 wherein the opening is cylindrical in configuration and has a central axis, the said central axis being angularly inclined from the vertical.
Claim 8
Dependent Claim
19 words
The invention of claim 4 wherein the support means include an elongate cable which interconnects the said support legs.
Claim 9
Dependent Claim
30 words
The invention of claim 5 wherein the support leg longitudinal position adjustment means include a plurality of longitudinally spaced holes and wherein the cable inserts into one of the holes.
Claim 10
Dependent Claim
47 words
The invention of claim 6 wherein the cable inserts into the holes above the top surface of the flotation member, the said cable preventing relative downward movement of each support leg relative to its associated flotation member by resting upon the top surface of the flotation member.
Claim 11
Dependent Claim
52 words
The invention of claim 7 and a washer resting upon the top surface of the flotation member beneath the cable, said washer surrounding the flotation member opening, whereby cable forces resulting from the weight of the support legs and the cover may be distributed about the top surface of the flotation member.
Claim 12
Dependent Claim
20 words
The invention of claim 5 wherein means are included to prevent movement of the support legs relative to the cable.
Claim 13
Dependent Claim
22 words
The invention of claim 9 wherein the cable also serves to equidistantly position the flotation members about the periphery of the pool.
