Benefits of technology

[0014] It is therefore an object of the present invention to provide a pool cover system that is relatively easy to operate.
[0015] It is also an object of the present invention, in accordance with one aspect thereof, to provide a pool cover system that provides a safety cover that may be operated by a single user.
[0016] It is a further object of the present invention, in accordance with one aspect thereof, to provide a pool cover system that provides a safety cover, but does not require major modification of the pool deck.

Problems solved by technology

While many pool cover devices have been developed, most are awkward and difficult to install and remove, thereby discouraging their use and inhibiting their benefits.
Such devices require a high-torsion power source, or a manually-operable crank arm, and are therefore cumbersome and laborious to operate.
As a result, such devices can be expensive to manufacture and install.
Installation of such a device is often too complex for a pool owner to attempt alone.
Additionally, should the electricity go out, the pool cover may not be able to be opened or closed, until power is restored.
Since the cover is not fixedly attached to the pool deck, the Graham device fails to provide a cover having a high degree of safety.
Similarly, Sartain fails to provide a safety cover and allows the pool to be unsafe even when covered.

Abstract

An apparatus for retracting a pool cover from over a pool, or extending a pool cover over a pool, includes a pool cover collecting drum supported for rotation on its ends, and a drive gear connected to the drum. A power gear for engaging the drive gear is operably connected to a portable, battery operated electric drill by a power shaft. When the drill is activated, the drive gear rotates the pool cover collecting drum to collect and retract the pool cover from over the pool. The pool cover is placed back over the pool by operation of a complementary apparatus on the opposite side of the pool, such as a rope spool collecting apparatus having an engageable drive gear. The gear-driven spool pulls on a rope attached to a rigid end or carrier of the pool cover. As the pool cover is extended and retracted it slides in a track, allowing the cover to serve as a safety cover. The gears may be located in a sealed housing filled with lubricant. The drive shaft may include a universal joint, and the drill may be designed to engage the power shaft with a flexible socket adapter.
