## Background
FIELD OF THE INVENTION
The present invention relates to a motion responsible swimming pool safety device for use in connection with swimming pool safety devices. The motion responsive swimming pool safety device has particular utility in connection with automatic rescue devices for swimming pools utilizing safety grids.
DESCRIPTION OF THE PRIOR ART
Motion responsive swimming pool safety devices are desirable for protecting young children from accidentally drowning in swimming pools. Many individuals do not own swimming pools for fear that their children will wander into the pool unnoticed. A need has been felt for a warning and rescue system that sounds an alarm when a pool is approached while the alarm is in place, sounding progressively more acute alarms as the water's edge is approached. Also, a safety grid rises when the water's surface is breached, thus preventing a drowning.
The use of swimming pool safety devices is known in the prior art. For example, U.S. Pat. No. 5,832,547 to Burroughs discloses a swimming pool automatic rescue device that is comprised of a safety net coextensive with the perimeter of the pool. The device is submerged in the water when inactive having metal arms fastened to corners thereof, hollow cylinders running from the pool bottom to just above the top of water surface standing at corners of the pool that house collapsible rods. In certain modes, minimal action by a human, namely operation of a remote activator, is necessary. When the swimming pool is not in use, an infra red signaling system is activated causing an electrical signal to travel through wires to activate motors at the bottom of each cylinder. However, the Burroughs '547 patent does not disclose a series of alarm perimeters that are set by laser beam, and does not have a laser beam sweep the water's surface to insure that there are no unsecured dead spots in the security grid, and does not have the capability of placing an emergency services phone call.
Similarly, U.S. Pat. No. 6,127,930 to Steffanus discloses a motion responsive swimming pool safety mat that is an automatically inflatable mattress adapted to rest on a bottom of a swimming pool in its deflated position. The device inflates using compressed air pumped through air inflation lines that are coiled around spring loaded hose reels. A microprocessor actuates a compressed air pump as a person interrupts a signal pattern produced by microwave sensors disposed around the perimeter of the swimming pool. The mattress uniformly rises up to the surface of the swimming pool to catch a distressed individual whose motion is detected after falling into the water. However, the Steffanus '930 patent does not disclose a series of alarm perimeters that are set by laser beam, does not have a laser beam sweep the water's surface and does not have the capability of placing an emergency services phone call.
Lastly, U.S. Pat. No. 4,129,905 to Niemirow discloses a swimming pool rescue net that can immediately rise to water's surface by means of inflatable bladder associated therewith to prevent drowning of endangered victims. However, the Niemirow '905 patent does not disclose a series of alarm perimeters that are set by laser beam, does not have a laser beam sweep the water's and does not have the capability of placing an emergency services phone call.
While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a motion responsive swimming pool safety device that allows automatic rescue devices for swimming pools utilizing safety grids. The Burroughs '547, Steffanus '930 and Niemirow '905 patents make no provision for a series of alarm perimeters that are set by laser beam, do not have a laser beam sweep the water's surface and does not have the capability of placing an emergency services phone call.
Therefore, a need exists for a new and improved motion responsive swimming pool safety device that can be used for automatic rescue devices for swimming pools utilizing safety grids. In this regard, the present invention substantially fulfills this need. In this respect, the motion responsive swimming pool safety device according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of automatic rescue devices for swimming pools utilizing safety grids.
