Bender, RU. Een SZ, Bakersfield, Calif. Filed .lune I3, liteit, Ser. No. 35,513 S Qlairns. (El. 4-I72) rIhis invention relates to a cover for swimming pools, and in particular to a flexible cover which may be quickly and easily applied and removed. A pool with no cover protection during periods of non-use presents several difficulties of maintenance, for instance, pollution by such foreign matter as dust, pollen, leaves, insects, and even small animals. A cover may also be saving of life in the case of small children. In another aspect it will tend to inhibit heat transfer and thus retain overnight a reasonable amount of the heat stored in the water by day. Conversely the heat content may be kept down during the day if so desired.
It is an object of the invention to provide a pool cover which is flexible, easily applied, and occupies small space when not in use.
Another object is to provide a pool cover which is selfpropelled in the pool-covering operation.
More particularly it is an object to provide a cover of sheet form which is stored in a roll when not in use.
Other objects are to provide a pool cover which is low in cost, easy of manufacture, facile in manipulation, low in weight yet with high strength, small in bulk, easily installed and removed, and readily portable.
Briefly described, the invention in a preferred embodiment will comprise an elongate spool on which is wound a flexible sheet whose outer end is anchored aiongione side of the pool, the flanges of the spool acting as rollers for carrying the sheet to pool-covering position in an unwinding operation, as well as in the wind-up process, and being powered by a motor carried on a dolly journalled on the axis of the spool.
For a more detailed description of the invention reference is made to the following specification, as illustrated in the drawings, in which:
FIGURE l is a plan view from above, showing the device in covering relation to a swimming pool;
FlGURE 2 is a sectional View along the line 2 2 of FIGURE l, on enlarged scale and broken away for the purpose of fore-shortening;
FIGURE 3 is a fragmentary view, in top plan, of the end of the spool carrying the drive means, on enlarged scale, with the cover in rolled-up condition;
FIGURE 4 is an end elevational View of the elements shown in FIGURE 3;
FIGURE 5 is a sectional View, enlarged, showing dctails along the line 5 5 of FIGURE 3;
FIGURE 6 is a sectional view, enlarged, along the line 6 6 of FIGURE l;
FIGURE 7 is a sectional view, enlarged, along the line '7--7 of FIGURE l; and
FIGURE 8 is a plan view from above, similar to FIGURE l, showing a modified cover and spool, adapted to a pool of odd shape.
Referring to the drawings by characters of reference, there is shown, in ElGURE l, a pool of rectangular outline having side walls, the top surfaces of which are indicated by the numerals it?, ll., l2 and i3 respectively. Offset a short distance from one of the longer walls, Il, of the pool is an anchoring block 14 running the length of the pool, and which may be secured in position by ground-engagirn7 spikes or other suitable means. The flexible sheet lo, which serves to cover the pool, is secured at one end to the block 14 as by upholstering tacks l or other means, such as staples. The other end of sheet i6 is secured to a tubular roller Ztl having end flanges 22, 24 and constituting a spool for storage of the sheet in a winding operation, as will appear hereinafter, and the spool being of a length such that the flanges are positioned to roll along the top of end edges It) and l2, respectively, of the pool. Thus, when the spool is rolled away from the anchor block 14, the sheet lo is progressively laid down over the pool in covering relation, and movement in the opposite direction progressively uncovers the pool while winding the sheet on the spool for compact storage. As seen at 26 in FIGURE 2, recesses 26 may be provided in the masonry of the pool to receive the end llanges of the spool, and thus inhibit movement of the spool in the extended position of the sheet. Such recesses may also-be provided on the sheet-storage side of the pool, adjacent the block 14.
Since there is no applied tension transversely of the sheet, stiffening means are provided in a series of'spaced, parallel ribs 23 (FIG. 6) extending across the sheet, and which may conveniently be contained in pockets 30. As shown the sheet consists of separate segments overlapped to form the pockets, being stitched as at 32 along each side of the pocket, but a similar result may be achieved by providing a single-piece sheet and sewing on extra, narrow Strips to provide the pockets. The sheet may consist of vinyl coated canvas or other suitable material, `and the -rib inserts may be of wood, for instance. These will preferably be spaced about 30 to 36 inches apart: The ribs are important, not only in giving rigidity to the cover when spread, but also to keep the cover from wriukling or bundling up when being rolled onto the spool.
As seen in FIGURE 7, the ribs 2S may be of a length to terminate at 34 near the pool edge or coping 36, with separate, terminal segments of rib 38 inserted in the ends of the pockets, so that the ends will lie down on the pool edge rather than to extend upwardly at an angle in continuation of the.y curve of the cover resulting from sag. Instead of using separate rib segments, the rib may be hinged at the pool edge, at point 34.
v The self-propulsion means for spreading and retrieving the cover is provided in a dolly indicated as a whole by the numeral di). In the form shown the dolly, or drive platform comprises a main frame i2 of angle stock which may be of steel, structural aluminum, or the like. Near one end, the horizontal member of the frame l2 carries an upright block 4d to the top of which is fixed a bushing sleeve 45 in which is journalled a shaft or spindle 48 fixed in spool flange 2d on the line of its axis and protruding outwardly. rlhe other end of the frame 42 is supported on a castor 5h which is secured to the underside of the bottom plate 52 of a battery box whose three sides S3, 54', 55 cooperate with the vertical member of the frame 42 to form an enclosure for a storage battery 56A which furnishes the motive power.
Driving is accomplished by a direct-current motor 58 mounted on the frame 42 and having an output shaft 66 with a spur gear 62 meshing with a larger gear 64 which is keyed to spool shaft 48, or which may be fixed to spool flange 24, the important point being that it revolve with the spool as one unit.
The operation of the device, in its main aspects, should now be apparent. Assuming the cover to be in stored condition, that is, rolled up on the spool, a reversing switch 66 on the carriage il@ is actuated to move the spool away from the anchor block 3.4i. In traversing the pool, the diameter of the roll of cloth will at any instant be less than the diameter of the ground-engaging spool flanges which provide the traction. As a result the payout of the cover lags the normal rate of advance or the flange rollers. I-lowever, this is readily compensated by slippage between the ange rollers and the traction surface. Rolling up of the cover, however, does not involve such inherent compensation, and in this operation the cover lags behind, as shown by the looped portion 68 in FIGURES 4 and 5. Therefore, means are provided for taking up this slack after the spool has reached the anchor block 14. Thus, each end face of the block 14 has secured thereto an upwardly opening section of channel 70, the upright walls 71, 72 of which have a pair or" aligned bores freely journalling the protruding, axial, end pins i4 of a roller 76. As seen in FIGURES 3, 4 and 5 the traction rol er langes Z4 of the spool enter the channels 76 at the end of the roll-up journey and move into contact with the free rollers 76, respectively. Any elort toward further movement of translation of the spool will tend to carry tbe flanges onto the rollers and thus lift them out or tractive engagement with the ground. As a result, the spool ilanges are free to rotate without advancing and the slack is consequently taken up.
In the case of pools of irregular shape, such as shown in FIGURE 8 and indicated by the numeral 78, the area of the cover may be minimized by providing a spool ange 80 on one end of the spool which is smaller in diameter than the flange 82 on the other end. The effective rolling surface is thus frusto-conical, and in the covering operation the sheet develops in a fan-like pattern providing an economy of surface. In this form, the rib pockets 30 are divergently disposed to comport with the over-all pattern and to be received on the spool, in each case, properly aligned in the length direction thereof.
While certain preferred embodiments of the invention have been shown and described, it will be understood that the same is not limited thereby, since various modications and substitutions will be apparent to those skilled in the art, in the light of this disclosure, and no limita tion should therefore apply except as shall be properly inferred from the spirit and scope of the appended claims.
