DETAILED DESCRIPTION

(8) Referring initially to FIGS. 1-3, depicted therein are various views of a signaling apparatus 110 for providing a submerged visible and audible signal for a swimming event or other activity. As illustrated the apparatus consists of several components including a handle 210, the handle including at least one electrical switch 220 at the top end of the handle. The electrical switch 220 may be a push-button type switch so that it is easily activated by pressing down on a flexible covering 224 at the upper end of handle 210. The handle 210 houses (stores) a telescoping extension pole 212 that both slides into the handle when collapsed for storage (collapsed position) and extends outward from the handle to reach an overall length of approximately 4-6 feet (expended position). The position of the extension pole may be held or locked into place by any releasable locking mechanism 216 (e.g., push-pin, twist-lock, lever, etc.), and may be stored within the handle. The extension pole is extendible from the collapsed position (e.g., FIGS. 1-2, 6A) to the extended position (e.g., FIG. 3, 6B). Moreover, with a twist-type locking mechanism the length of the pole during use may be adjusted to any desirable length between the collapsed and extended lengths.

(9) At the distal end of the extension pole 212 a water-tight signaling housing 240 is attached. Included in the signaling housing is a transparent portion 244 for the transmission of light 234 from a light source 246 located within the transparent portion. The use of the transparent portion allows for viewing of the light source, when activated (see e.g., FIGS. 5A-6B), by a swimmer or other competitor within the pool. The signaling housing 240 also includes an audible signaling device such as a transducer (e.g., speaker, buzzer, piezo-buzzer, horn, sounder) at location 248 that is used to produce an output sound, note or alarm.

(10) Apparatus 110 further includes a self-contained power source (e.g., a 9V battery) 310 at the bottom of the signaling housing as depicted in FIG. 4, connected to the electrical switch. It will be appreciated that the battery may be rechargeable, and that a wireless (e.g., inductive) charger may be employed, or a charging connection may be wired near the switch on the other end of the apparatus so as to avoid its submersion. Once the pole has been extended or adjusted to a desired length by a user, the user (e.g., meet official) activates the switch (ON) and the light source and the audible signaling device are both energized and produce light and sound, respectively. The apparatus 110 may be moved at the end of the lane in front of an approaching swimmer as illustrated by the series of illustrations set forth in FIGS. 5A-5C.

(11) As further depicted in FIG. 6A, for example, the light source 246 may include a plurality of light-emitting diodes (LEDs) that are energized in response to the switch being activated. For the audible signaling device at location 248, while a number of water-proof sound generation devices or techniques may be employed, the embodiments depicted include a piezo-electric sound generating chip at location 248 that, like the LEDs 352, is energized and outputs a tone when the switch 220 is activated. Thus, the swimmer that is approaching a final lap is alerted to that fact by the light and tone emanating from the submerged signaling housing.

(12) As will be appreciated by those familiar with electronic components such as LEDs and piezo-electric chips, the apparatus may further include control circuitry connected to the battery power source, wherein the light source and audible signaling device, in response to the electrical switch, cause the flow of electrical current to the light source and the audible signaling device, and both then generate, respectively, visual and audible signals. Furthermore, the construction of the LED light array may be similar to that disclosed in co-pending U.S. application Ser. No. 14/924,312 previously incorporated by reference in its entirety, and as more specifically described relative to FIG. 7 below.

(13) As depicted in FIG. 4, in one embodiment of apparatus 110, signaling housing 240 includes a self-contained power source (battery) therein. The signaling housing is intentionally constructed in a watertight manner, and a threaded cap 250 includes a gasket or O-ring 252 therein to assure a watertight seal when fastened to the bottom of the fitting or cap 366 on signaling housing 240.

(14) Further considering the detailed illustration of FIG. 7, depicted therein are additional components in the signaling housing 240 used as part of the signaling apparatus. In particular, within portion 244, which is generally tubular in shape, is included a cylindrical transparent or translucent tube 316. A tape or ribbon 352 of single- or multi-colored light-emitting diodes (LEDs) is spirally wrapped about a cylindrical core 354 and the wrapped core is inserted within the translucent outer tube 316 after electrical connections are made to wires 326. The tube has, at one or both ends, a sealable fitting or cap 366 applied to the ends thereof to hold the LEDs inside and to prevent the LEDS from environmental exposure (e.g., water-tight to prevent leakage when submerged).

(15) Depending upon the configuration, one of the fittings or caps may include a hole or aperture to allow wires 326 to pass through and up to switch 220 (e.g., FIG. 1) located at the opposite end of the apparatus, at or near the top of the extendible pole. Moreover, the wiring is connected to the electronic circuitry in the housing 240 and provides power/signals to the LED tape 352 as well as the transducer at 248, in order to control the on/off state (and possibly color, flashing pattern, etc.) of the LEDs and the transducer. It will be appreciated that while a push-button switch 220 may be employed to simply control the LED light source as on or off, the push-button switch, in conjunction with control circuitry, may also be used to select a color of the light and/or a flashing pattern for the LEDs 352.

(16) It should be understood that various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present disclosure and without diminishing its intended advantages. It is therefore anticipated that all such changes and modifications be covered by the instant application.
