Metal detector

Metal detector search coil

A ground search metal detector with a pivotally mounted search coil that locates a stem connector at either of a storage position or an operational position. The operational position locates the connector adjacent to the central portion of the search coil to facilitate useful operational characteristics, and the storage position locates the connector adjacent to the perimeter edge to facilitate compact storage of the metal detector by pivoting the stem to overlap the search coil.

A hermetically sealed metal detector includes a plastic housing with an integrally formed diaphragm having a predetermined area and a thickness that enables vibration thereof by an internal acoustic transducer. An alert signal audibly drives the transducer in response to a metal detector circuit. The acoustic transducer is positioned to align the transducer output port adjacent to the interior surface of the diaphragm, which enables coupling of the acoustic signal through an air gap to vibrate the diaphragm. A cover is disposed about the diaphragm on the exterior of the housing. The cover has a vent formed therethrough for enabling passage of the acoustic energy to the exterior of the housing. Light and battery hermetic sealing are also presented.

A metal detector has multiple transmit and receive coils for producing multiple detection fields. In one embodiment, a transmit coil is combined with two receive coils in a configuration that enables the detector to generate two detection fields, one being substantially narrower than the other. The transmit coil is inductively balanced with the receive coils such that the transmit coil induces minimum signals in each of the two receive coils. A metal target lying within a detection field changes the coupling between transit and receive coils and produces signals in the receive coils. The received signals are utilized to identify the target's presence within one or both of the detection fields. The use of two detection fields, substantially different in size, enables the metal detector to search over a broad area for object detection and then narrow the search to more precisely locate the detected object. A further embodiment has two transit coils and one receive coil and likewise produces a broad and a narrow detection field.

An adapter is provided for attaching decorative articles to shoelace tips. The adapter is small and inconspicuous with an outer cylindrical shape only about one inch in length and one quarter of an inch in outer diameter. The adapter has at one end a fitting for releasable securement to a decorative article, such as a light stick. At its opposite end the adapter is hollow and defines therewithin a plurality of coaxial sockets of decreasing diameter proceeding from the shoelace attachment end toward the decorative article receiving end. Each of the sockets preferably has a plurality of radially inwardly directed ribs that aids in frictionally engaging the stiffened tip of a shoelace within a socket of corresponding size. The adapter may be attached to the stiffened plastic tips of shoelaces to fasten decorative articles, such as light sticks to the shoes of a wearer.
