FR2762487A1 - Metal detector system mounted detachably to shoe sole +so user is not apparent - Google Patents

Abstract

The device finds buried metal objects without user obviously looking for them, and adaptable to all types of shoe. The device comprises an enclosed electronic circuit (1), an enclosed battery (2), an emitting and receiving coil for electromagnetic waves (3) integral with a detachable sole, a visual alarm (4), an audible alarm (5), and straps (7) for attaching to a shoe. The detecting coil within the sole is connected by a wire (6) to the battery and electronic circuit held in a bag which can be attached to the belt of the wearer or hung over his shoulder. The device can be adapted to indicate whether the detected device is ferrous or non-ferrous. The detection system works by detection of a change in the received electromagnetic field, which is due to metallic object. A water-tight version is available.

Description

-1 - The present invention relates to a detection method embedded in

  a sole allowing to find metallic objects (pkièces, blJoux, etc)

  they have been lost and this without specifically looking for them.

  Metal detection is traditionally carried out by a generously bulky detector (approximately 1 m high by 15 cm in diameter) and used during outings specifically intended for the search for metals. The device according to the invention makes it possible to remedy this drawback. I will ra

  mleux understood with reference to the figures.

  l [a ure 1 r represents a sole within which is integrated or molded

  Ao- the detection system comprising an electronic bofler (1), a boler containing the plle or batteries (2), a reel emitted and re.

  however of electromagnetic waves by Induction (3), a light indicator (4), an audible alarm (5), straps or hooking system 7). this semell can be attached to or under any type of import5. footwear (city, sport, mountain, walking, beach, etc ... etc ... this list is not exhaustive).

  As soon as the walker encounters a various metallic object under his feet, the sound signal will be activated by the fact that the magnetic field will be distorted; being therefore modMlf, h sound nozzle will emit a signal.

  2- Figure 2 represents a sole in which is molded or integrated the emitting coil] ce-receptor of electromagnetic waves (3) this sole being connected by a 6) an electronic bolfer (1) located either at the waist of the pants , solt in a pocket of the garment or at all

  another part of the body, even in a bag.

  _ This electronic bolwer includes an indicator light (4) a sound alarm

  re (5) warning the walker during a meeting with a metlW- object

  whatever it is This sole being also adaptable to any cholsle shoe by the

  walker (city, sport, mountain, basketball, skiing, etc., etc.).

-2-

  Figure 3 represents a variant of Figure 2.

  It is a sole comprising a transmitting coil (3) connected to a transmitter (8) and to a boltier containing a battery or an accumulator (2>

  When the walker encounters a metallic object, the coil, by r Inter-

  5. transmitter medal, sends a radio or infra-red signal to the electronic bolt (1) located on the person's belt. r audible alarm (5)

  or the indicator light (4) located on the bolter is triggered, averIs-

  health of the presence of an object under the feet of the walker.

  Figure 4 represents the complete detection system which can be Ao. completely hidden in any bag (10) clothing

  or any object or accessory worn by the walker.

  (non-exhaustive list). The soles of Figures 1 and 2 are characterized by

  the fact that they can be waterproof.

  The fibure 5 has an elongated pocket (12), made of fabric, plstque 45. or any other mnatklau in which is integrated the entire detection system for batteries or accumulators (2), electronic shoemaker (, coils (emitters and reptrles) (3), an audible alarm (5), an indicator light (4), the assembly connected by wires (6), the pocket's interior is accessible from the top by a closure

  suitable (11), this pocket includes loops (7) with loops or self-

  - sticky which allows to wrap or fix this dltbpoche around the ankle, foot or shoe of the person concerned, the coil of deectxon being below. the shape of the pocket being of little importance. This

  pocket also exists with option of total waterproofness.

  The metal detection systems referred to in this description 15. - can be supplied with energy by any process other than batteries o

the above named batteries.

-3-

  This rocWdé has several advantages.

  - It is not bulky It allows while walking (for example, on a beach, in

  the forest, and. etc.) to find metals (jewelry, coins, etc., etc.).

  S. - The soles and the pocket fit on any type of shoes (city, sport, mountain, walking, walking, beach, swimming,

etc., etc..).

- It is not visible.

  -11 allows group games between children or adolescents (objects

voluntarily concealed).

  -A version of these soles exists with a discrimination function allowing to distinguish between ferrous and non-ferrous metals.

  -A second version of these soles is planned in waterproof version.
