Abstract
SWIMMING POOL COVER WITH
A FLOATING FORWARD EDGE
ABSTRACT OF THE INVENTION
A swimming pool cover constructed from a flexible impervious material wherein the leading or forward edge of the flexible impervious material is adapted with a floating member is disclosed. The swimming pool cover herein described is adapted with a longitudinal beaded side edge which is slid-ably held within a longitudinal, open channel or track cut into a side way member mounted to the longitudinal margins of a swimming pool and in close proximity to the surface of the water. The leading or forward edge of the cover is also beaded to be received within a track or channel fixed to an elongated floating member. Perferably the elongated floating member is an elongated hollow tube closed at both ends by an expandable stopper fitted with a means to insure a sealing arrangement and thereby prevent water from leaking therein.
A power means is also provided for extending and retracting the pool cover at will.

When pool covers are used on relatively na'rrow pools or if the track or channel strip is positioned at a height substantially close to the surface of the water, the pool cover can be extended or retracted without incident.

In addition, any dirt that may have been collected on the pool may also be wa,shed into tlle pool and t-hereby incrcase the do~-time that would be required in cleanlng the pool.

Objects of the Invention:
To remedy the above problems, it is the primary object of this invention to provide a swimming pool cover which will not dip or submerge below the water surface during extension of the pool cover. Another object of this invention is to provide a swimming pool cover having a floatable leading or forward edge which will remsin above the surface of the water and thereby prevent dipping of the covers leading edge during extension.
Still another object of this invention is to provide a floating pool cover which can be mounted to the pools side wall at or near the surface of the water.
Summary of the Invention:
In its broadest form the present invention provides an extendable and retractable floating swimming pool cover adapted for use on a swimming pool having side walls comprising a flexible impervious sheet having a beaded longitudinal side edge for engaging a longitudinal channel mounted to the side walls of a swimming pool and a beaded forward leading edge, a channel means for engaging and holding the beadet forward leadlng edge, and a floating member fixed to the channel means for holding the beaded forward leading edge, the floating member having a diameter of such size that a flow of water over the pool cover is minimized during the cover extension process.

10~6706 DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in FIG. 1 the swimming pool cover shown generally by the numeral 10 is adapted with a pool cover 12 having a floatable leading or forward edge 14. A
means for extending and retracting the pool cover is housed within a well identified generally by the numeral 16. As shown more clearly in FIG'S. 2 and 3, the pool cover includes a flexible impervious sheet 12 adapted with a longitudinal beaded side edge 18 held by a track or channeled guide way means 20 flxed to the underside 22 of a pool's overhand 24.
The leading or forward edge of the pool cover also contains a bead 30 substantially similar to the bead found on the pool cover's longitudinal side edge. The beaded side and forwar* edge is formed by sewing, gluing or otherwise securing a folded reinforcing flexible member to either the longitudinal side edge or forward edge or the pool cover. In the instant situatîon, the beaded side and forward edge is constructed~iby inserting a draw-cord 25 betwéen the folds of the pool caver and stitching same to form a bead or thickened side member.
If desired, the side and front edges of the pool cover may contain a reinforcing member sewed or otherwise attached to the edges of the pool cover. In such a sit-uation, the draw-cord would be inserted in between the folds of the relnforcing member stitched as stated above In the embodiment shown the drawcord runs the entire longitudinal length ~f the pool cover and extends out-wardly from the~front edge of the pool cover and around a pulley rotatably mounted in a plane horizontal to the pool. Rotatable attachment of the pulley may be achieved by securing the pulley to the wall of the front section of the swimming pool. In operation, the draw-cord passes around the 104~;706 pulley and into a return longintudinal open channel or track 27 cut in the side way member which, as previously indicsted was attached to the upper side of the pool's overhang 24. The end of the draw-cord is connected to a motorized spool (not shown) rotatably mounted within the well 16. When the motorized spool is energized, the spool is rotated causing the draw-cord to be collected thereon.
The forward bead 30 is held within a track or chan-nel 32 fixed to an arm 34 which in turn is mounted to a hollow elongated tubular member 36. To insure that the hollow tubular member will not take in water and thereby lose its floating charactertics, expandable plugs 38 and 40 respectively are provided for insertion into each end of the elQ~gated tube. The plugs are held in sealing contact with the inner walls of the tubular member by a bolt 42 and wing not 44. To prevent the stopper from being deformed during tightening of the wing nut, the stopper is expanded against the internal walls of the tubular member insuring a water tight seal-ing engagement and thereby prevent water from entering therein.
The tubular member can be constructed from any light weight material, such as the plastics or metals.
Non-corrosive metals such as aluminum are prefèrred.
If a plastic material is used, it should be of the type which will withstand decomposition or deterioration when exposed to chlorinated water. The end stoppers can be constructed from any readily expandable material such as rubber, neoprene or the various plastics. Wood and similar materials can also be used if desired. The limi-tations set forth above relating to the tubular member, would also be applicable in choosing a material for con-struction of the stopper.
In pools having a length of fron about 20 to 30 feet, and a width of about 12 to 20 feet, the tubular member fixed to the leading or forward edge of the pool cover will generally have a diameter of from about 2 to 4 inches. As the width of the pool increases, or if the pool's water is subjected to windy conditions wich would cause turbulance, the diameter of the hollow tubular member should preferably be increased.
Although certain preferred embodiments have been illustrated and described herein above, it should be understood that various changes may be made without de-parting fromthe spirit and scope of the disclosed inven-tive concept, which is limited only by the claim appended hereto.
