## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is related to and claims benefit to provisional application Ser. No. 60/621,136, filed Oct. 22, 2004, which is hereby incorporated by reference in its entirety.


BACKGROUND OF THE INVENTION
Technical Field
The present invention relates to a searchlight, and more particularly to a searchlight for a watercraft or other suitable vehicle or vessel.
SUMMARY OF THE INVENTION
The present invention provides a new and unique searchlight featuring a controller having a 2-speed joystick and a center home position, a bayonet/security locking and mounting system, or some combination of one or more of these features.
The controller having the 2-speed joystick allows a searchlight selection of slow and fast rotational options to be chosen separately from spot/flood beam options. For example, the two-speed joystick allows for the searchlight selection of the slow and fast rotational options, while a first separate button or key allows for providing the searchlight selection of a spot beam option, and a second separate button or key allows for providing the searchlight selection of a flood beam option. Embodiments are also envisioned in which one button controls both the spot/flood beam options.
The “center home” position feature provides a one-touch controller pad that returns the searchlight to its customary forward pointing/on centerline position after use.
The bayonet mounting/security locking system features a base, a mounting plate and at least one locking bolting. The base is coupled to the light and has at least one mounting member. The mounting plate is for coupling the base to the device such as a boat and has at least one aperture for receiving the at least one mounting member. Each of the at least one locking bolt is coupled to a respective one of the at least one mounting member, the at least one locking bolt requiring a special matching locking wrench to tighten and loosen the same making theft of the light from the device substantially more difficult.

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1: The Searchlight
FIG. 1 shows a searchlight generally indicated as 10 according to the present invention, having a search controller 12 (also known herein as a searchlight controller pad), a searchlight controller module 14 and a searchlight assembly 16.
In operation, the search controller 12, which is described in greater detail in FIG. 2, responds to manual user inputs for controlling the basic operation of the searchlight according to the present invention, including turning the searchlight on/off, moving the searchlight up/down and left/right, moving the searchlight fast/slow, providing SOS signaling and/or one-touch center control, providing spotlight or floodlight functionality, etc., consistent with that shown and described herein, and provides a searchlight controller signal along the line 12a to the searchlight controller module 14 containing information about the manual user inputs for controlling the basic operation of the searchlight.
The searchlight controller module 14 which is described in greater detail in FIG. 3, responds the searchlight controller signal along the line 12a, processes this signal, and provides a searchlight controller module signal along the line 14a to the searchlight assembly 16 containing information about commands for electromechanically controlling the basic operation of the searchlight consistent with that shown and described herein.
The searchlight assembly 16 which is described in greater detail in FIGS. 4-5, responds to the searchlight controller module signal along the line 14a and turns the searchlight on/off, moves the searchlight up/down and left/right, fast/slow, provides SOS signaling, provides the one-touch centerline, provides spotlight or floodlight functionality, etc., consistent with that shown and described herein.
FIG. 2: The Searchlight Controller Pad 12
FIG. 2 shows the searchlight controller pad 12 in FIG. 1 in greater detail, including a keypad 18 having a 2-speed joystick 20, an SOS key 22, a sweep key 24, a spot mode key 26, a flood mode key 28 and an on/off key 30 for providing for the functionality including turning the searchlight on/off, moving the searchlight up/down and left/right, moving the searchlight fast/slow, providing SOS signaling and centerline, providing spotlight or floodlight functionality, etc.
2-Speed Joystick 20
In operation, the 2-speed joystick 20 moves the searchlight up, down, left, right, and at 45 degrees angle, i.e. 45 degrees to the upper right, upper left, lower right, and lower left. In addition, the 2-speed joystick 20 provides the searchlight with a two-speed operation, including a slow speed when held for the first 3-5 seconds, a fast speed after 3-5 seconds, and a control resets operation back to slow speed when released by the user or operator. In operation, the 2-speed joystick 20 allows a searchlight selection of slow and fast speed rotational options to be chosen separately from the spot/flood beam options. In the prior art, the “slow speed/spot beam” and “fast speed/flood beam” have historically been linked in function. According to the present invention, now the user or operator of the controller 12 can choose speed and beam pattern separately via the 2-speed joystick 20 and the “spot” and “flood” touch pad buttons or keys 26 or 28. The functionality of the 2-speed joystick 20 may be implemented in the 2-speed joystick module 54 in FIG. 3, consistent with that discussed below.
The aforementioned description of the 2-speed joystick 20 is provided by way of example only. The scope of the invention is not intended to be limited to any particular length of time or range of time that the user holds the 2-speed joystick to achieve the desired functionality; and embodiments are envisioned in which the 2-speed joystick is held for a different time, such as 1-3 second, 1-4 seconds, 2-4 seconds, etc. to achieve the desired functionality.
Moreover, 2-speed joysticks are known in the art and the scope of the invention is not intended to be limited to any particular type or kind thereof either now known or later developed in the future. In addition, a person skilled in the art would be able to adapt a known 2-speed joystick to implement and perform the functionality shown and described herein.
The SOS Key 22
In operation, when pressed by the user the SOS key 22 activates SOS signaling in the current lamp head position after a 2 second hold; a second press activates a 30 degrees incremental rotation and signaling function; and a third press cancels signaling and rotation and the searchlight stays on. The functionality of the SOS key 22 may be implemented in the SOS signaling module 56 in FIG. 3, consistent with that discussed below.
The aforementioned description of the SOS key 22 is provided by way of example only. The scope of the invention is not intended to be limited to any particular ordering of the functionality of the SOS key 22 when pressed, the length of time pressed or the number of degrees of the rotation. For example, embodiment are envisioned having a different ordering of the functionality of the SOS key 22 when pressed, a different length of time pressed, a different number of degrees of the rotation, or some combination thereof.
The Sweep Key 24
In operation, when pressed by the user the sweep key 24 activates a 20 degrees left/right sweep feature in spot/slow mode and activates motors and lamps/lights if not already on; while a second press deactivates the sweep function and the lamp stays on.
The aforementioned description of the sweep key 24 is provided by way of example only. The scope of the invention is not intended to be limited to any particular ordering of the functionality of the SOS key 24 when pressed, the length of time pressed or the number of degrees of the sweep. For example, embodiment are envisioned having a different ordering of the functionality of the sweep key 24 when pressed, a different length of time pressed, a different number of degrees of the sweep, or some combination thereof.
The Spot, Flood and On/Off mode Keys 26, 28, 30
The spot mode key 26, the flood mode key 28 and the on/off key 30 respectively switch the searchlight to a spot mode, a floodlight mode or power the lamps and motors on/off. In addition, the on/off key 30 also kills power to lamps and motors. Back lighting may be green when the power is “off” (same as other key or button); and amber with the power “on.” This functionality may be implemented in the modules 60, 62, 64, consistent with that discussed below.
Moreover, the on/off key 30 may be pressed and held for 1 second to return the searchlight head to centerline. In this embodiment, if the lamp is “on”, it will remain on after the light centers; if the light is off, the lamp head will center without activating the lamps; power to the motors will then turn off at the end of the movement. In effect, the “center home” feature that provides a user or boat owner with a one-touch controller pad function that returns the searchlight 10 to a customary forward pointing/on boat centerline searchlight position after use. This “center home” feature eliminates the need to attempt adjustment to the preferred centerline positioning using a joystick or 8-way touchpad when often the searchlight body cannot be seen by the operator. The functionality of the sweep key 24 may be implemented in the module 56 in FIG. 3, consistent with that discussed below. However, the scope of the invention is not intended to be limited to implementing the “center home” feature in the “on/off” key 30; embodiments are envisioned in which this feature is implemented in another key, such as the sweep key 24 or some other suitable key.
