Description

UNDERWATERFLOTATION SAFETYDEVICE
Background and Summary of the Invention
This invention relates generally to a water safety device. In particular, the present invention relates to a flotation safety device housed underwater.
In the United States alone, approximately 350 children under five years old drown in pools each year. Among unintentional injuries, drowning is the second leading cause of death for this age group, and another 2,600 children are treated in hospital emergency rooms each year for near-drowning incidents. Furthermore, adults also drown and become injured annually in pools.
In response to this, many different water safety (flotation) devices are found in the art, such as in U.S. Pat. Nos. 913,617, 4,549,871, 4,560,356, 5,030,152, and 5,823,840, and various monitoring and tracking systems have been devised, such as those disclosed in U.S. Pat. No. 6,064,309, U.S. Pat.
App. Pub. No. 2004/0121782, and U.S. Pat. App. Pub. No. 2004/0113836.
While assumably effective for their intended purposes, the existing devices do not provide a flotation, device that is housed underwater to assist a struggling person and that automatically alerts an emergency contact and activates a remote alarm. It would be desirable to have a safety device having these features in order to prevent or minimize injuries and to save lives.
Summary of the Invention
A safety device according to the present invention includes a base that may be positioned under the water surface of a swimming pool or other body of water by utilizing ballast, a hook for fastening the base to a pool floor, or other similar fastening mechanism. The safety device further includes a buoyant member selectively and releasably attached to the base and adapted to also be positioned below the water surface. The safety device further includes a transmitter in communication with a sensor that is able to detect when the buoyant member is released from the base. Accordingly, the transmitter transmits a signal through the air when actuated by the sensor. An alarm unit remote from the base and transmitter includes a receiver for receiving the signal. Further, the alarm unit includes another transmitter capable of transmitting an emergency signal upon receiving a signal from the base transmitter. .
The buoyant member is releasably attached to the base with a coupling that may be manipulated by a person. More particularly, the coupling includes a pair of attachment members and a compression collar. A release strap is connected to the compression collar for selectively causing the collar to bear against the compression arms and to thereby release the buoyant member from the base.
Accordingly, a swimmer who is in distress in the pool may dive to the safety device and pull the release strap. This action causes the buoyant member to be released so as to pull the swimmer quickly to the water surface.
Simultaneously, the sensor detects the separation between the buoyant member and base and actuates the transmitter so as to signal the remote alarm unit to summon aid.
Therefore, a general object of this invention is to provide a safety device that is housed underwater when not in use.
Another object of this invention is to provide a safety device, as aforesaid, that is easy to use.
Still another object of this invention is to provide a safety device, as aforesaid, that has a buoyant member releasably attached to a base in a manner that allows the buoyant member to be quickly and easily detached from the base.
Yet another object of this invention is to provide a safety device, as aforesaid, that automatically alerts an emergency contact and activates a remote alarm. A further object of this invention is to provide a safety device, as aforesaid, that is reliable and requires minimal maintenance. Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.

A water safety device according to the present invention will now be described in detail with reference to Figs. 1 through 7 of the accompanying drawings. More particularly, a safety device 100 for use in a body of water 10 having a water surface 12 and a floor surface 14 includes a buoyant member
110 releasably coupled to a base 120. The body of water 10 is preferably contained in a pool 2, and the floor surface 14 is preferably a floor surface of the pool 2.
Means 130 are included for positioning the base 120 beneath the water surface 12 and preferably adjacent the floor surface 14. The means 130 preferably includes a ballast 130a (Fig. 2B) or a hook 130b (Fig. 2B) attached to the base 120 although a suction cup, bolts or other anchors, an adhesive, or any combination of the aforementioned means would also be suitable. The buoyant member 110 is coupled to the base 120 such that the buoyant member 110 is also located beneath the water surface 12 when the buoyant member 110 is coupled to the base 120.
The buoyant member 110 preferably defines a substantially vertical channel 112 having a channel surface 112a, and a coupling 140 is positioned adjacent a lower end of the channel 112 for releasably attaching the buoyant member 110 to the base 120. The coupling 140 preferably includes a pair of opposed attachment members 142 and a compression collar 146.
As best shown in Figs. 4A to 4D, each attachment member 142 has a first end 142a attached to the buoyant member 110 and a second end 142b releasably coupled to the base 120, and each attachment member 142 has a compression arm 144 extending downwardly therefrom. The first ends 142a are preferably attached to the channel surface 112a to make the coupling 140 accessible from the channel 112. The compression collar 146 is adjacent the compression arms 144 for movement between a first configuration 146a surrounding the compression arms 144 and a second configuration 146b bearing against the compression arms 144. A release member 150 (Fig. 3A) is accessible inside the channel 112 and is attached to the coupling 140 for manipulating the coupling 140 to selectively release the buoyant member 110 from the base 120 (Fig. 4D). The release member 150 is preferably a release strap 150a (Figs. 3A and 4B) attached to the compression collar 146 for moving the compression collar 146 from the first configuration 146a to the second configuration 146b when the release strap 150a is pulled by a user.
A wrist strap 160 has an end 160a attachable to the buoyant member 110, and the wrist strap 160 forms a loop 160b for attachment to a user's wrist (Fig. 3A). The loop 160b is positionable adjacent the channel surface 112a and may be selectively retained adjacent the channel surface 112a by a retaining member 164 (Fig.4B). The retaining member 164 extends from the base 120 along the channel surface 112a for retaining the loop 160b adjacent the channel surface 112a when the buoyant member 110 is coupled to the base 120 and for releasing the loop 160b from adjacent the channel surface 112a when the buoyant member 110 is released from the base 120.
A first transmitter 170 is connected to the buoyant member 110 for selectively transmitting a signal (Fig. 3 A, and an alarm unit 180 having a receiver 182 and an alarm 184 is remote from the first transmitter 170 (Fig. 5). Although not essential, the first transmitter 170 may be secured within a transmitter case 171 with lid 171a. A sensor 172 is in communication with the first transmitter 170 for detecting a release of the buoyant member 110 from the base 120 and actuating the first transmitter 170 when the buoyant member 110 is released from the base 120 (Fig. 3A). The alarm unit 180 preferably also includes means 186 for activating the alarm 184 when the receiver 182 receives a signal from the first transmitter 170, means 187 for automatically alerting an emergency contact when the alarm unit receiver 182 receives the signal, a button 181, means 188 for alerting the emergency contact when the button 181 is activated, and a speaker 185 and a microphone 183 for allowing communication with the emergency contact after the emergency contact has been alerted (Fig. 5). The means 186 for activating the alarm 184 preferably includes circuitry or a CPU with programming electrically connected to the receiver 182 and the alarm 184 (Fig. 5).
As more particularly shown in Fig. 6a, the means 187 for automatically alerting the emergency contact preferably includes circuitry or a
CPU 187a with programming electrically connected to the receiver 182 and a second transmitter 187b. The circuitry or the CPU 187a with programming causes the second transmitter 187b to transmit a signal (such as a cellular signal, a signal through a telephone line, a signal over the internet, etc.) when the alarm unit receiver 182 receives the signal from the first transmitter 170.
As more particularly shown in Fig. 6b, the means 188 for alerting the emergency contact preferably includes circuitry or a CPU 188a with programming electrically connected to the button 181 and the second transmitter 187b. The circuitry or the CPU 188a with programming causes the second transmitter 187b to transmit a signal (such as a cellular signal, a signal through a telephone line, a signal over the internet, etc.) when the button 181 is activated.
In use, the base 120 is positioned beneath the water surface 12 by the means 130. The buoyant member 110 is then coupled to the base 120 such that the buoyant member 110 is also located beneath the water surface 12. This is preferably done by moving the compression collar 146 to the first configuration 146a and positioning the second ends 142b of the attachment members 142 to engage the base 110.
To use the safety device 100, a user dives to the buoyant member 110, reaches inside the vertical channel 112, and pulls the release strap 150a.
Pulling the release strap 150a moves the compression collar 146 from the first configuration 146a to the second configuration 146b, causing the second ends
142b of the attachment members to release the base 120.
The buoyancy of the buoyant member 110 causes the buoyant member 110 to rise away from the base 120 and to reach the water surface 12.
The sensor 172 detects the release of the buoyant member 110 from the base 120 and actuates the first transmitter 17O5 causing the first transmitter 170 to send a signal. As the buoyant member 110 separates from the base 120, the wrist strap 160 is separated from the retaining member 164. Depending on the type of loop 160b, the wrist strap 160 may then tighten around the user's wrist, ensuring that he gets carried to the water surface 12 along with the buoyant member 110.
When the alarm unit receiver 182 receives the signal from the first transmitter 170, the means 186 (preferably the attached circuitry or CPU with programming) activate the alarm 184. The means 187 (preferably the appropriate circuitry or programming in the CPU and the second transmitter) automatically alert the predetermined emergency contact. More particularly, the circuitry or programming in the CPU preferably cause the second transmitter to transmit a signal to the emergency contact when the alarm unit receiver 182 receives the signal from the first transmitter 170. Once the emergency contact has been alerted, the microphone 183 and the speaker 185 allow communication with the emergency contact.
The means 188 for alerting the emergency contact when the button 181 is activated may be used independently of the release of the buoyant member 110 from the base 120. In other words, someone may activate the button 181, and the circuitry or programming in the CPU then causes the second transmitter 187b to transmit a signal to the emergency contact. This allows someone standing near the alarm unit 180 to quickly alert the emergency contact.
It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
