Swimming pool cover assembly
Abstract
The present invention is directed to a swimming pool cover
assembly useful to facilitate the installation of a cover having
the tendency to sink when placed on the surface of the pool. The
cover assembly comprises a plastic sheet and a flotation device.
The sheet has a size and configuration generally adapted to cover
the water surface of the pool, a top side, and a bottom side
provided with one or more fasteners. The flotation device has one
or more complimentary fasteners to permit assembly to and
disassembly from the bottom side of the sheet. The floatation
device also has sufficient buoyancy to maintain the sheet at or
near the water surface when the sheet and attached floatation
device are placed on the water during installation of the cover
over the pool.

Claims
1. A cover assembly for a water filled swimming pool comprising: a
plastic sheet having a size and configuration generally adapted to
cover the water surface of the pool; the sheet also having a top
side and a bottom side provided with one or more fasteners; a
floatation device having one or more complimentary fasteners to
permit assembly and disassembly of the floatation device to the
bottom of the sheet; the floatation device having sufficient

comprises an elongated tube having the complimentary fasteners
arranged along the length of the tube.
5. The pool cover of claim 1 wherein when the sheet and floatation
device are disassembled both are capable of being folded into a
relatively compact form to facilitate storage.
6. The pool cover of claim 1 wherein the floatation device
comprises a plurality of buoyant members each having at least one
complimentary fastener.
7. The pool cover of claim 1 wherein the plastic sheet is comprised
of a plastic material having a specific gravity greater than 1.
8. The pool cover of claim 1 wherein the plastic sheet is a
polyvinyl chloride file.
9. The pool cover of claim 4 wherein a plurality of elongated tubes
comprise the floatation device.
Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates, generally, to covers for use
on outdoor swimming pools and, more particularly, to a cover
assembly useful for covering a swimming pool with a relatively
heavy material that tends to make the cover sink when placed on the
water.
[0002] It is well known in the swimming pool trade that covers can
be very useful in protecting the pool and reducing the amount of
debris that otherwise would find its way into the pool water
without the cover. This is particularly true when the pool will be
out of service for extended periods of time, such as over the
winter months. One category of pool cover that has been found
advantageous is the PVC cover which is relatively opaque and
reduces pool water contamination by reason of photosynthesis. While
PVC pool covers have enjoyed significant success in the market,
they nonetheless suffer from the disadvantage associated with the
high density of the PVC. When first placed on the pool surface
during installation they tend to sink below the water surface,
making the remaining installation process more difficult.
[0003] It would be desirable if a PVC pool cover assembly were
devised that would retain the advantages of PVC covers and yet
facilitate the installation of these PVC covers.
SUMMARY OF THE INVENTION
[0004] The present invention is directed to a swimming pool cover
assembly useful to facilitate the installation of a cover having
the tendency to sink when placed on the surface of the pool. The
cover assembly comprises a plastic sheet and a flotation device.
The sheet has a size and configuration generally adapted to cover
the water surface of the pool, a top side, and a bottom side
provided with one or more fasteners. The flotation device has one
or more complimentary fasteners to permit assembly to and
disassembly from the bottom side of the sheet. The floatation
device also has sufficient buoyancy to maintain the sheet at or
near the water surface when the sheet and attached floatation
device are placed on the water during installation of the cover
over the pool.
[0005] In accordance with one embodiment of the invention the
floatation device takes the form of an elongated tube having a foam
core and is fastened to the bottom side of the sheet by means of
Velcro fasteners. The tube and core are most preferably pliable
with little shape memory so that the tube may be easily folded or
rolled up for storage.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] The novel features which are characteristic of the present
invention are set forth in the appended claims. However, the
invention's preferred embodiments, together with further objects
and attendant advantages, will be best understood by reference to
the following detailed description taken in connection with the
accompanying drawings in which:
[0007] FIG. 1 is a perspective view illustrating one preferred
embodiment of the present invention as placed over a typical
swimming pool during installation;
[0008] FIG. 2 is a cross sectional view taken along line 2-2 of
FIG. 1; and
[0009] FIG. 3 is a perspective view showing the disassembled
components of the cover assembly, with the sheet and floatation
device folded for convenient storage.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] With reference to FIG. 1, one preferred embodiment of the
pool cover assembly of the present invention is shown positioned
over a typical in-ground swimming pool. The cover assembly includes
a sheet of plastic material 10 and a floatation device 12.
[0011] The plastic sheet 10 may be made from a polyvinylchloride
film and has a size and configuration adapted to fit over and fully
cover the pool. A typical weight for sheet 10 is about 8 to 12
ounces per square yard or a film thickness in the range of 15-16
mils. While illustrated as rectangular in FIG. 1, sheet 10 can have
any shape as necessary to completely cover the pool. Plastic sheet
10 has a top side 14 and a bottom side 16, with one or more
fasteners 18 appropriately attached to the bottom side.
[0012] The floatation device is depicted here to comprise an
elongated tube having a tube wall 20, with one or more
complimentary fasteners 22 fixed to the tube wall and adapted to
cooperate with fasteners 18, thereby permitting assembly of the
tube to the underside of the sheet. The illustrated fasteners are
Velcro patches, but any of a number of other fasteners such as
snaps, buttons, hooks and so forth may also be used. The fasteners
18 and 22 permit the assembly and disassembly of the floatation
device 12 to sheet 10. The elongated tube acts as a housing for a
core 24 having a relatively low density so that the floatation
device 12 has sufficient buoyancy to maintain the cover assembly at
or near the surface of the pool when the cover assembly is first
placed on the water during the initial steps of cover installation.
A variety of materials may be used to form the core 24, including
various foams, cork, or pellets. It is particularly preferred that
the core 24 be made of a material that has little or no resilient
or shape memory, such as loosely packed Styrofoam pellets, so that
upon disassembly of the cover both the sheet 10 and the floatation
device 12 may be compactly folded for storage, as illustrated in
FIG. 3.
[0013] In FIG. 1, the floatation device 12 includes two tubes
running down the longitudinal length of the sheet 10. However, a
single tube placed along the centerline of the sheet 10 may be
employed. The present invention also contemplates other floatation
device configurations, such as square, rectangular, triangular or
circular pillow shapes.
[0014] It will be appreciated by those skilled in the art that
other changes and modifications can be made to the illustrated
embodiments without departing from the spirit of the present
invention. All such modifications and changes are intended to be
covered by the appended claims.
