Stern running lighting apparatus

Abstract

A stern running light is pivotally attached to the mast of a shallow water anchor system thereby avoiding the need for a separate stern running light. The top end of the mast holds both a pivotable cluster of LED lights that emit light in a 360 degree horizontal plane and, below it, a flood light in a clear plastic housing for task lighting within the fishing boat to which the mast is attached. A power cord for the stern runs to the battery for the mast from the stern running light and flood light. The mast of the shallow water anchor is at a height suitable to meet stern running light height requirements and the use of white LEDs meets light visibility requirements.

DETAILED DESCRIPTION

(10) Referring now to FIGS. 1 and 2, a watercraft is shown as a motorized, propeller-driven fishing boat 10 that includes an outboard motor 12 mounted to a stern 14 and two shallow water boat anchors 16 mounted to the stern 14 lateral to outboard motor 12. The shallow water boat anchor 16 comprises at least one mast 18 with a spike 20 affixed to a telescoping cylindrical tube 22 that can extend a total of 2.4-3.0 meters (10 or 12 feet) into the bottom surface 24 of the body of water 26 to hold fishing boat 10 in position and prevent drift.

(11) Fishing boat 10 has a light system 28 at the top of mast 18 that includes a stern running light 32 and a flood light 36. Light system 28 is connected to a battery 40 that is also used to start outboard motor 12 and to provide power to a motor 44 for mast 18.

(12) Stern running light 32 directs light in a 360 horizontal plane, parallel to the surface 48 of the water 52 and elevated to a height of at least one meter as indicated by line 56 above deck 60. Stern running light 32 may comprise a cluster of white, ultra-bright, light-emitting diodes (LEDs) which can be seen up to two miles away, and thus meeting US Coast Guard requirements. LEDs are also long-lived, compact, cooler, and use less energy than incandescent lights.

(13) Flood light 36 directs a beam of light from stern 14 of boat 10 toward bow 64 that is wide enough to illuminate the interior 68 of fishing boat 10 with task lighting. Task lighting is intended for illuminating tasks performed by the user 72, such as rigging a fishing line, cutting bait, and so on. Flood light 36 may be provided by LEDs, with the number and brightness of the LEDs being selected to provide the appropriate amount of task lighting.

(14) As shown in FIGS. 3-5, to modify a typical shallow water boat anchor 16, a cap 76 on top of the mast 18 is removed and replaced by light system 28. FIG. 3 shows cap 76 being unfastened after the removal of four screws 80 that secured it to mast 18. Light system 28 is then mounted to mast 18 in place of cap 76 by affixing it to the top of the mast 18 with screws 84, as seen in FIG. 4, which screws 84 may be a different length than that of screws 80 to accommodate light system 28 compared to cap 76. As an alternative, light system 28 may be affixed to mast 18 by the use of adhesives.

(15) A power cord 88 running from stern running light 32 and flood light 36 may be threaded between mast 18 and motor 44 when run to battery 40 particularly if mast 18 has an axial channel 92. Power cord 88 may fit conveniently into channel 92. FIGS. 4 and 5 show a power cord 88 running from the bottom of light system 28, threading down along mast 18 and terminating at battery 40, which powers light system 28 and shallow water boat anchor 16. Clips 96 may be used to secure the power wire 38 to axial channel 92 of mast 18. Battery 40 may be a 12 volt, direct-current battery.

(16) Comparison of FIG. 1 and FIG. 5 will show stern running light 32 in two different positions. Stern running light 32 pivots between a horizontal, stored position as seen in FIG. 5, and a vertical, deployed position, as seen in FIG. 1. Stern running light 32 is pivoted between the stored and deployed positions by first pressing button 100 to unlock stern running light 32 from light system 28 and then moving stern running light 32. Releasing button 100 allows stern running light 32 to lock again when in either the stored or deployed position.

(17) FIG. 6 shows an exploded view of the light system 28. Light system 28 comprises a top cover 104, a lamp lid plate 108, a LED lamp housing 112, and a lamp lower plate 116. Top cover 104, lamp lid plate 108 and lamp lower plate 116 may be made of metal, such as aluminum. The components of the light system 28 are fastened together with screws 84 through corresponding holes 124 in the top of mast 18.

(18) LED lamp housing 112 holds the LEDs that provide illumination for flood light 36. LED lamp assembly includes a top 128 and a bottom 132 with a frame 136 between them that has a recess 140 dimensioned to receive first LED set 144 that provides illumination for flood light 36. Top 128, bottom 132 and frame 136 may be made of clear acrylic and, when secured together, provide a water-tight housing for first LED set 144.

(19) Top cover 104 grips lamp lid plate 108 and lamp lower plate 116, with LED lamp housing 112 between them. Top cover 104 also includes a stop 106, the function of which will be described below. A second bracket 152 has a U-shape for receiving a lamp arm 156, which holds a second LED set 160. The U-shape of second bracket 152 arises by forming upstanding flanges 154 that oppose each other. Lamp arm 156 is pivotally attached to second bracket 152 using a pivot latch mechanism 164. Lamp arm 156 is limited in its pivot from the stored position to the deployed position by stop 106.

(20) As best seen in FIG. 7, pivot latch mechanism 164 includes a two-part shaft with a first part 172 being hollow and a second part 176 being solid. A compression spring (not shown) is inside the first part 172 and is pressed on the by second part 176 when it is inserted into the first part 172 First part 172 and second part 176 can be squeezed together against the compression spring.

(21) At the end of second part 176, a square nut 180 is attached. A ring 184 with an outer diameter larger than square nut 180 is attached to the square nut 180 by a screw 188 that threads to the interior of the square nut 180 through the center of ring 184.

(22) Upstanding flanges 154 of second bracket 152 and lamp arm 156 have opposing square holes 192, 196, respectively, that correspond with each other and with square nut 180 in size and relative alignment, so that square nut 180 can fit through square holes 192, 196, and to thereby lock second bracket 152 and lamp arm 156 together when square nut 180 is seated in square holes 192, 196. By pressing on the ring 184, square nut 180 can be moved axially, out of square holes 192, 196 of upstanding flange 154 of second bracket 152 and of lamp arm 156 so lamp arm 156 can pivot with respect to second bracket 152. Releasing ring 184 allows square nut 180 to again seat in square holes 192, 196 so that second bracket 152 and lamp arm 156 are again locked together, either in the stored position (FIG. 5) or the deployed position (FIG. 1). Movement of lamp arm 156 from the stored to the deployed position acts as a stern running light switch to turn on second LED set 160.

(23) In FIG. 8, there is illustrated a simple wiring diagram for the present lighting system 28 showing stern running light 32 and flood light 36 connected to battery 40 and to a switch 200 which may be located with the instrumentation of boat 10 or other convenient place on boat 10, and an additional switch 204 that may be located on light system 28 and is closed by the pivoting of stern running light 32 to the deployed position from the stored position. It will be clear that the two circuits are shown as separate circuits and are separately activated.
