This invention relates to navigation lights for boats and more particularly to a retractable navigation light for boats.
Retractable cleats and other similar devices are widely used within boats for securing mooring lines and the like thereto. These retractable cleats typically include a base member, and a retractable cleat member that is telescopingly received within the interior of the base.
Navigation lights are an important safety feature for all boats, especially when the boat is used during the evening hours or in inclement weather, where visibility by other boats is reduced. Navigation lights are required for all recreational boats. Required lights include a red light visible from the port side of the boat, a green light visible the starboard side of the boat and a white light such as a stern light. For safety reasons, the red (port) and green (starboard) must be visible from dead ahead to 112.5 degrees aft on each side and the white all-around light must be visible for a full 360 degrees.
For many boats, such as flats boats, a trolling motor is often mounted on the bow. This trolling motor, as well as other obstructions, often blocks visibility of most gunnel mounted navigation lights. One solution to this problem is to raise the navigation lights to a height greater than the trolling motor. This is often done with a pole or other extension, raising the navigation lights around 12-18 inches above the deck or surface of the boat to clear the obstruction.
A fixed pole can also raise a light above obstructions, but most fishing happens during daylight hours and the fixed pole will get in the way and cause a tripping/safety hazard. A removable pole is one solution to this problem, but this solution has several limitations. First, the removable pole is easy to misplace, lose, or drop overboard. Second, the pole must include electrical contacts to complete a circuit when the pole is installed. The electrical contacts often corrode, causing failure or sporadic operation, especially after exposure to salt-water.
Another solution is a motorized retracting/extending light that uses a motor to extend a telescoping pole with navigation lights at the end. This solution reduces issues related to losing the pole and contacts, but introduces several other problems including reliability of the motor that performs the extending, excess cost, added weight of the extension mechanism, etc. One would not want to be out on a boat at night when the motor failed and the navigation light does not extend.
What is needed is a manually extendable/retractable navigation light that is installed into the deck or gunnels of a boat.
A retractable navigation light mounts through a surface of a boat. The retractable navigation light, in the retracted position, is substantially flush with the surface/deck to which it is mounted, thereby reducing clutter and tripping issues. The an illumination section of the retractable navigation light, in the extended position, is elevated sufficiently as to position signal light above any obstruction such as a trolling motor, etc. The illumination section locks in the extended position so as to not retract as the boat pounds against waves and unlocks with the push of a button when it is desired to retract illumination section. In some embodiments, the extension shaft on which the light(s) are mounted is sufficiently sturdy as to provide a safety handle should one slip on the deck of the boat.
In one embodiment, a retractable/extendable boat light is disclosed including a stationary portion and a manually extendable/retractable portion. The stationary portion has at least one screw hole for accepting a fastener to mount the stationary portion in a hole of a surface of an aquatic vehicle. The stationary portion is stationary with respect to the aquatic vehicle (e.g. it moves as the aquatic vehicle/boat moves) and the stationary portion has a holder cavity and a shaft retaining section that are positioned such that, when mounted in the hole, the holder cavity and the shaft retaining section are below the surface of the aquatic vehicle.
The manually extendable/retractable portion includes an extension shaft and an indicator portion. The extension shaft passes through and fits snuggly within the holder cavity of the stationary portion. The indicator portion is fixedly attached to a first end of the extension shaft and includes at least one lamp and at least one lens. The at least one lens allows light from the at least one lamp to exit the indicator portion. The indicator portion sized and shaped to fit within the holder cavity.
The extension shaft includes a stop situated on an outer surface of an end of the extension shaft that is distal from the indicator portion.
The extension shaft also includes a locking device that locks the extension shaft in an extended position wherein the indicator portion is positioned outside of the holder cavity and above the surface of the aquatic vehicle.
In another embodiment, a retractable/extendable boat light for mounting in a hole of a surface of an aquatic vehicle is disclosed. The retractable/extendable boat light includes a stationary portion and an manually extendable/retractable portion. The stationary portion has a fastener surface with at least one screw hole. The stationary portion is mounted to and stationary with respect to the aquatic vehicle. The stationary portion has a holder cavity and a shaft retaining section that are positioned such that, when mounted in the hole, the holder cavity and the shaft retaining section are below the surface of the aquatic vehicle. A bottom surface of the holder cavity includes a ramp.
An extension shaft passes through and fits snuggly within the holder cavity of the stationary portion and an indicator portion is fixedly attached to a first end of the extension shaft. The indicator portion has at least one lamp and at least one lens, the at least one lens allowing light from the at least one lamp to exit the indicator portion. The indicator portion sized and shaped to fit within the holder cavity.
A stop (e.g. a fixed peg) protrudes outwardly from the distal surface of the extension shaft and the stop contacts a lower surface of the shaft retaining section, thereby preventing the extension shaft from exiting the shaft retaining section.
A locking peg and a release button are affixed to a first leg of a u-shaped spring and the u-shaped spring which is situated within the extension shaft such that the locking peg and the release button are urged outwardly through holes in a first side of the extension shaft by a force of the u-shaped spring wherein a second leg of the u-shaped spring pushes against a distal side of the extension shaft. As the indicator portion is pulled towards an extended position, the ramp engages with the release button, thereby deforming the u-shaped spring and moving both the release button and the locking pin inwardly with respect to the extension shaft until the release button and locking pin slide smoothly within the holder cavity. The release button and locking pin restore to their extended position after clearing a top surface of the holder cavity in which position the locking pin abuts the top surface of the holder cavity, thereby locking the extension shaft in the extended position until the release button is manually depressed for moving the extension shaft towards a retracted position.
In another embodiment, a retractable/extendable boat light for mounting in a hole of a surface of an aquatic vehicle is disclosed. The retractable/extendable boat light includes a stationary portion and an manually extendable/retractable portion. The stationary portion has a fastener surface with at least one screw hole and is mounted to and stationary with respect to the aquatic vehicle. The stationary portion has a holder cavity and a shaft retaining section that are positioned such that, when mounted in the hole, the holder cavity and the shaft retaining section are below the surface of the aquatic vehicle. A bottom surface of the holder cavity includes a ramp.
The manually extendable/retractable portion includes an extension shaft and an indicator portion. The extension shaft passes through and fits snuggly within the holder cavity of the stationary portion. The indicator portion is fixedly attached to a first end of the extension shaft and has at least one lamp and at least one lens, the at least one lens allowing light from the at least one lamp to exit the indicator portion. The indicator portion sized and shaped to fit within the holder cavity.
There is a stop which is a fixed peg that protrudes outwardly from the distal surface of the extension shaft. The stop contacts a lower surface of the shaft retaining section, thereby preventing the extension shaft from exiting the shaft retaining section.
A locking peg and a release button are affixed to a first leg of a u-shaped spring and the u-shaped spring is situated within the extension shaft such that the locking peg and the release button are urged outwardly through holes in a first side of the extension shaft by a force of the u-shaped spring. A second leg of the u-shaped spring pushes against a distal side of the extension shaft. The ramp engages with the release button as the indicator portion is pulled towards an extended position, thereby deforming the u-shaped spring and moving both the release button and the locking pin inwardly with respect to the extension shaft until the release button and locking pin slide smoothly within the holder cavity. After clearing a top surface of the holder cavity, the release button and locking pin restore to their extended position the locking pin abuts a top surface of the holder cavity, thereby locking the extension shaft in the extended position until the release button is manually depressed for moving the extension shaft towards a retracted position.
The invention can be best understood by those having ordinary skill in the art by reference to the following detailed description when considered in conjunction with the accompanying drawings in which:
Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures. Throughout this description, the term “boat” refers to any aquatic vehicle of any size or type including, but not limited to, boats, yachts, jet skis, kayaks, canoes, a dingy, rafts, pontoon boats, etc.
Referring to
As shown in the example of
The stationary portion 31 is affixed to the boat 5. It is preferred that the stationary portion 31 is fitted within a hole (not shown) made in a surface of the boat 5, the hole preferably being just slightly larger than the outer dimensions of the holder cavity 34 and smaller than the outer perimeter dimensions of the fastener surface 38. After the stationary portion 31 is placed in the hole, one or more fasteners (e.g. screws) are used to hold the stationary portion 31 to the surface of the boat 5. For example, the screws pass through holes 32 in the fastener surface 38 and into/through the surface of the boat 5 as known in the industry.
The stationary portion 31 has a shaft retaining section 36, through which the extension shaft 20 passes. It is preferred that the shape and size of the cross section of the inner surface of the shaft retaining section 36 substantially matches the shape and size of the cross section of the extension shaft 20. In such, the extension shaft 20 fits snuggly within the shaft retaining section 36 and is allowed to move in and out of the shaft retaining section 36 as the indicator portion 12/14/16/18/40 is extended or retracted. In one embodiment, the cross sectional shape of both the extension shaft 20 and the shaft retaining section 36 is oval or oval with flattened sides. This oval cross sectional shape prevents the extension shaft 20 from being rotated within the retaining section 36 and provides a move comfortable hand grip as opposed to a cross-sectional shape that has pointed edges (e.g. rectangular, triangular, etc.). For navigation lights, it is preferred that the extension shaft 20 not be rotatable with respect to the retaining section 36 to maintain the relationship of the red lamp/lens 16 to the port side and the green lamp/lens 16 to the starboard side.
In a preferred embodiment, a flexible wire 17 connects the lamp(s) 16 with a source of power when illumination is desired. In some embodiments, there is no flexible wire 17 and the lamp(s) 16 is/are powered by a power source within the indicator portion 12/14/16/18/40 such as batteries (not shown). In such, it is also anticipated that a solar cell be located on the top surface of the indicator cover 12 for recharging of the power source.
To facilitate lifting the indicator portion 12/14/16/18/40 out of the holder cavity 34, finger grips 40 are provided on an upper surface of the indicator portion 12/14/16/18 while finger spaces 42 are provided on the fastener surface 38, allowing a user to position fingers beneath the finger grips 40 to lift the indicator portion 12/14/16/18/40 out of the holder cavity 34.

As the extension shaft 20 continues in the upward direction, the release button 24 is wedged inwardly by the ramp 39 and is held in an inward position by the inside surface 37 of the shaft retaining section 36 at least until the locking peg 26 engages with the ramp 39, at which time the ramp 39 wedges the locking peg 26 inwardly into the extension shaft 20 until the extension shaft 20 completes the upward movement, at which both the release button 24 and the locking peg 26 clear the shaft retaining section 36 and both extend outwardly under spring tension of an internal spring 28 (see
Referring to
To pull the indicator portion 12/14/16/18/40 upward from the stationary portion 31, one places a finger in one recess 42 and a thumb in the other recess 42, squeezes to hold the indicator portion 12/14/16/18 by the tabs 40, and then pulls the indicator portion 12/14/16/18/40 upwardly out of the holder cavity 34 until the locking peg 26 engages as described above, holding the indicator portion 12/14/16/18/40 in the extended position.

For certain boats 5, especially fishing boats 5 (e.g. flats boats 5), fishermen often walk in all portions of the deck. In such, even if there are no obstructions to visibility of the retractable boat light 10, it is advantageous to retract retractable boat light 10 during daylight hours to reduce the possibility of tripping, etc.
In some embodiments, the retractable boat light 10 is made of a sturdy material such as steel or stainless steel such that, the extension shaft 20 doubles as a handle which is useful in, for example, emergency situations.
Although the retractable boat light 10 has been described with red and green navigation indicator lamps 16, any color lamp is anticipated for any other application, including a white lamp 16 for mounting on the stern of a boat 5.
Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.
