Description

LIGHTED DIVE BUOY

FIELD OF INVENTION

A dive buoy with a lighted display to indicate the presence of a diver in the area. The buoy includes a floatation device with a lighted display that can be selectively illuminated. A flag may also be carried by the floatation device.

BACKGROUND OF THE INVENTION

Buoys are well known in the art. They are of particular importance to scuba divers to mark their location below to boaters and the like to reduce the risk of accidents. The diver's flag is well known, is attached to a floatation device, and may be anchored in place or tethered to a diver for movement with the diver. The flag and float may also be tethered to a boat. While effective, the use of a flag on a float does present problems, particularly in low light and choppy water. In addition, some boaters do not understand the significance of a diver's flag or are aware that they should look for one.

Another problem with a diver's flag is that it pitches with waves in the water. This occurs because there is no ballast associated with the float to which the flag is attached. The float will retain the flag in a generally upright orientation when there is ballast associated with the float.

The ballast may be internal or external of the float. Even with ballast, the flag will pitch with the float when the float is in choppy water and not be readily visible to all boaters.

Thus, theie is a need for an improved diver's flag or indicator which is readily visible regardless of the conditions under which it is displayed.

SUMMARY

The present invention involves the provision of a dive buoy for scuba divers. The buoy includes a floatation device. The buoy is provided with means to maintain the floatation device in a generally upright orientation. A light transmissive panel is associated with the floatation device and includes indicia to indicate the presence of a diver in the area. A power source is associated with the floatation device and is connected to a light source. The light source cooperates with the panel for selectively illuminating the panel to highlight the indicia. A tether device is associated with the floatation device.

Accordingly, it is an objective of the present invention to provide a diver flag or indicator which is highly visible. It is a further objective of the present invention to provide an indicator for use with divers which is also visible from beneath the surface of the water.

It is yet another objective of the present invention to provide an indicator for use with divers that may be used in conjunction with a life ring.

It is still a further objective of the present invention to provide an indicator for use with divers which employs reflective surfaces for greater visibility. It is still yet another objective^^" the present invention4α provider indicator for use with divers which employs lights for greater visibility in low light conditions.

It is still yet a further objective of the present invention to provide an indicator for use with divers which may be readily assembled and disassembled for storage when it is not in use.

DETAILED DESCRIPTION OF THE INVENTION

While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described presently preferred embodiments with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.

The reference numeral 1 designates a dive buoy attached to a boat 2 by a tether 4. The buoy 1 includes a display panel 6 that can be selectively illuminated and preferably also includes a diver's flag 8 as well. Diver's flags are well known in the art and have a diagonal white stripe 10 and a red background 11. The flag 8 may be rigid to stay fully exposed. The buoy 1 includes a floatation device 14. The flag 8 may be mounted on a rod or mast 12, that in turn is mounted to the floatation device 14.

Figures 2, 3, 6 illustrate one form of floatation device 14. As shown, the floatation device 14 is generally spherical and has a bore 16 adapted to receive the rod 12 therein for mounting. The rod 12 may be removably secured to the floatation device 14 as by threaded engagement at 18. In use, the floatation device 14 has a top portion 19 and a bottom portion 20 with the rod 12 extending outwardly from the top portion 19. (As used herein, orientation terms are used to indicate positions when the buoy is in its normal orientation for use.) Ballast 22 can be provided and can be positioned in the interior of the floatation device 14 or positioned outside of the floatation device. As seen in Figures 3, 4, the ballast 22 is suspended from the floatation device as with a hanger assembly 24. The ballast 22 is an orientation device which maintains the floatation device 14 in a generally upright position. A plurality of ballasts 22 can be utilized if desired. The hanger assembly 24 may be removably mounted to the floatation device 14 as by extending into the bore 16 from the bottom portion and be threadably coupled to the floatation device, or may be suspended from one or more attachment devices 26 secured to an outer wall 28 of the floatation device. The attachment devices 26 can also be used to attach a tether or anchor line to the floatation device 14 from a vessel or land.

The floatation device 14 of Figure 2 is shown as being generally spherical. It is to

and the like. It should also be noted that the floatation device can be constructed from a luminescent, e.g. glow in the dark, or otherwise illuminating material. Preferably the outer wall 28 of the floatation device is constructed from a translucent material. This permits the passage of light from the interior of the device to the exterior so that the device may be seen from a distance. It should further be noted that the floatation device can be used by itself for use as a channel or crab trap indicator or the floatation device may be used with pre-existing dive flag components to add functionality thereto. The floatation device may also include reflectors or mirrors positioned on its outer diameter to further reflect light. The outer wall 28 can also be made from a mirror like or reflective material. The illustrated floatation device 14 is constructed to provide access to the interior 30 for the mounting of a power source 32 and a light source 34. In the illustrated embodiment, the floatation device can have portions releasably connected together as at 36 as by threaded engagement, bayonet mount and the like. The power source 32 is coupled to the light source 34 and is operable to selectively power the lamps 35 of the light source. Preferably, the lamps 35 are of a high efficiency type such as LED's. A switch, not shown, can be connected between the power source 32 and the light source 34 for selective illumination of the light source 34. The switch may include an emergency mode that causes the lights to blink and may additionally cause a siren to sound. A preferred power source 32 includes a battery pack 38 using rechargeable batteries. Also preferred as part of the power source 32 is one or more solar cells 37 coupled to the battery pack 38 to provide electrical energy to the battery pack 38 to effect recharging by converting light energy to electrical energy. The solar cells 37 can be mounted to the wall 28 for exposure to light, such as sunlight. In a preferred embodiment, the wall 28 can be light transmissive by being transparent or translucent at least in selected areas. The solar cells 37 can then be mounted in the interior 30. In a preferred embodiment, the rod 12 is also constructed to be light transmissive and hollow, contain light members that may be illuminated with the floatation device 14 and/or the display panel 6. Lamps can also be placed on the exterior of the floatation device 14 to enhance its visibility. The lamps on the exterior of the floatation device and the translucent material of the outer wall 28 enable lights to be directed downwardly so that an ascending diver or someone under the water can observe the floatation device. This feature enables the device to be utilized as a reference point for divers to return to their boat or platform.

of floatation device 14. The GPS device 39 can communicate with satellites in orbit to determine the exact location of the floatation device. The GPS device may be provided with its own antenna or it may employ rod 12 as an antenna. The GPS device can display the location of the floatation device 14 on the exterior of the floatation device so that the location may be readily observed by anyone in the vicinity of the floatation device. A digital wireless communications device 41 can also be positioned within the interior of the floatation device. The digital wireless communications device can be placed in communications with other communication devices on land or other vessels. The digital wireless communications device 41 can transmit the location of the floatation device to other communication devices on land or on other vessels by utilizing the GPS device 39. The digital communications device 41 can function similar to On Star® devices used in automobiles. Alternatively, the digital communications device can operate one way only, i.e. transmit only when activated. The device 41 can be manually actuated or be programmed to be actuated whenever the diver or other person utilizing the floatation device is in danger. For example, if the device 41 is moved violently, if the device 41 comes in contact with water, if the device 41 is not actuated for a period of time (which would indicate that the diver cannot retrieve the floatation device and may be in danger), etc. The display panel 6 can be configured for exposure and visibility in several configurations as seen in the various Figures. As seen in Figure 2, the display panel 6 is mounted in the interior 30 and is associated with the light source 34 for illumination of the display panel. As shown, the light source 34 is positioned interiorly of the display panel 6 to backlight the display panel. This allows for the light source 34 to simultaneously illuminate more than one display panel 6. The display panel 6 may be provided with indicia 40 for illumination and communication to a viewer that a diver may be in the area and to proceed with caution. The indicia 40 on the display panel can be a diver's flag similar to flag 8 secured atop rod 12, in Fig. 1. While the display panel 6 is shown as having indicia applied thereto for illumination, it is to be understood that the panel could also be an LCD or plasma screen that can be illuminated and display an image stored in a memory transmitting light through portions thereof. The display panel 6 can be mounted to the outer wall 28 which can be light transmissive for illumination by backlighting. The display panel 6 may also be positioned on an outer surface

with each panel facing a different direction. Each panel can be illuminated by a light source 34.
