## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to metal detectors and more particularly pertains to a new metal detection system with a magnetometer head coupleable to conventional footware and method of use for facilitating hands-free detection of metals below a surface of the ground adjacent to a user.
2. Description of the Prior Art
The use of metal detectors and shoe-mounted electronics is known in the prior art. Illustrative examples include U.S. Pat. No. 3,947,756; U.S. Pat. No. 6,286,235; and U.S. Pat. No. 6,408,545.
While these devices fulfill their respective, particular objectives and requirements, the need remains for a system that allows hands-free operation of the magnetometer assembly and provides greater flexibility of operation for the user.
SUMMARY OF THE INVENTION
An advantage of the present invention is its operational capability of scanning an area behind the user for treasure hunting, or an area ahead of the user for either treasure hunting, line detection or mine detection.
Another advantage of the present invention is audio signaling corresponding with the detection of metal below the surface allowing the user to look at the surrounding environment rather that at a control panel or indicator meter.
Yet another advantage of the present invention is the capability of using a single system coupled to one piece of conventional footware, or using two systems, each coupled to an associated piece of conventional footware thereby doubling the effective area covered.
To this end, the present invention generally comprises a magnetometer assembly, a control assembly, and a coupling assembly. The magnetometer assembly is designed for passing over a surface and detecting metal below the surface. The control assembly is operationally coupled to the magnetometer assembly, and facilitates operational control of the magnetometer assembly. The coupling assembly operationally couples the magnetometer assembly to a piece of conventional footware.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new metal detection system with a magnetometer head coupleable to conventional footware and method of use embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 4, the metal detection system with a magnetometer head coupleable to conventional footware and method of use 10 generally comprises a magnetometer assembly 20, a control assembly 30, and a coupling means 40.
The magnetometer assembly 20 is designed for passing over a surface and detecting metal below the surface. The control assembly 30 is operationally coupled to the magnetometer assembly 20, and facilitates operational control of the magnetometer assembly 20. The coupling means 40 operationally couples the magnetometer assembly 20 to a piece of conventional footware 2.
Preferably the control assembly 30 further comprises a housing 32, which may be coupled (coupleable) to an article of clothing of a user facilitating hands-free operation. Suitable articles of clothing include, but certainly are not limited to belts, vests, shirts, pants, hats, headbands, or any other article of clothing which may conveniently retain the housing 32.
The coupling means 40 may be any number of devices or mechanisms to either selectively or permanently coupled the magnetometer assembly to the conventional footware 2. These might include, but at not limited to straps, belts, screws, buttons, snaps, adhesives, zippers, rivets, or other suitable devices. Preferably, the coupling means 40 includes a strap assembly 41 designed for is secured around a heal portion of the conventional footware 2. The strap assembly 41 includes a first end 42 positionable adjacent to a first side of the conventional footware 2. The strap assembly 41 also includes a second end 43 positionable along a second side of the conventional footware 2 and over a top of the conventional footware 2. The second end 43 is selectively securable to the first end 42. Thus, the strap assembly 41 is selectively secured to the conventional footware 2.
While any number of methods may be used to selectively secure the first end of the strap assembly 41 to the second end of the strap assembly 41, such as buttons, snaps, buckles, zippers and the like, the preferred method is hook and loop fastener. Preferably, the strap assembly 41 further comprises a first portion of hook and loop fastener 44 operationally coupled to the first end 42 of the strap assembly 41 and a second portion of hook and loop fastener 45 operationally coupled to the second end 43 of the strap assembly 41. The first portion of hook and loop fastener 44 is complementary to the second portion of hook and loop fastener 45.
The magnetometer assembly 20 may be in communication with the control assembly 30 either through a wired connection or a wireless connection.
In at least one embodiment the control assembly 30 further comprises an aural alert generator 34. The aural alert generator 34 emits an aural alert when the magnetometer assembly 20 detects metal. The aural alert generator 34 facilitates signaling the user of a presence of metal below the magnetometer assembly 20.
In a further embodiment, an extension means 50 is operationally coupled between the strap assembly 41 and the magnetometer assembly 20. The extension means 50 facilitates placement of the magnetometer assembly 20 away from a foot of a user. Preferably, the extension means 50 further comprises a horizontal extent 52 and a vertical extent 54. The horizontal extent 52 includes a first end operationally coupled to the strap assembly 41. The horizontal extent 52 facilitates holding the magnetometer assembly 20 at a predetermined lateral distance from the foot of the user. The vertical extent 54 may be operationally coupled between a second end of the horizontal extent 52 and the magnetometer assembly 20. The vertical extent 54 facilitates a vertical placement of the magnetometer assembly 20 above a surface.
In still a further embodiment the extension means 50 is designed for positioning the magnetometer assembly 20 in front of the user.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
