Background

This invention relates to the security of a watch or similar style device which is utilising GPS or other types of tracking systems such as Wi-Fi or cellular location systems designed to be worn on the wrist or other suitable place on the body.

When a Child or Person with limited capacity is given a GPS style watch or other wearable based device capable of using GPS or other means to locate there position and or location, or to notify someone of an emergency or abduction the watch or other wrist style unit can be removed by undoing the strap and disposing of the GPS watch or similar wrist warn device.

This defeats the purpose of the tracking unit in ensuring the wearer is safe.

The use of conventional watch or wrist style straps are insufficient to maintain the security features of the device to be of proper and effective use.

The Integrated Locking Mechanism locks the watch, GPS unit or other style tracking unit to the wearers wrist or other appropriate part of the body.

This ensures that the watch, GPS unit or other type of tracking unit cannot be removed without the lock key or similar style unit.

This maintains the integrity, the proper security and effective use of the watch, GPS unit or other wearable type of tracking system in an emergency or abduction scenario.

The Integrated Locking Mechanism by way of it's incorporated cable ensures that the watch, GPS unit or other type of wearable tracking unit cannot be cut off by shears or another style or type of cutting device or mechanism thus ensuring the proper security and effective use of the watch, GPS unit or other type of wearable tracking system is maintained in an emergency or abduction scenario.

The Integrated locking mechanism and cable is designed to be embedded into a Rubber or Silicone/Rubber compound or other flexible material style wrist or other type of wearable strap.

The cable section 31 runs from the receiver unit 1 to the steel plate 34 where it is held by a curved clamp in the steel plate and then the cable 31 returns back to the receiver unit 1.

The cable section 31 runs from the lock unit 15 to the steel plate 34 where it is held by a curved clamp in the steel plate and then the cable 31 returns back to the lock unit 15.

Fig: 26 illustrates a further configuration of the steel cable comprising a twin cable pin attachment system. The pin holder 35 holds the two cables 31 by way of a clamp-style pressure holder attached to the pin at two places.

The pin holder 35 has two threaded screw holders at each end to accommodate a screw attachment to the arms of a watch or similar style unit.

Fig: 27 illustrates a further configuration of the steel cable which comprises only/exactly a single cable in each strap. The Pin Holder 36 is similar to the pin holder 35 but has only a single clamp-style pressure holder to hold the cable 31 at the central point of the pin holder 36. Fig: 28 illustrates another configuration of the lock unit which is curved. A curved style lid 37 is utilised instead of the flat style lid 14 in order to give a lower profile for straps used on a watch or similar device for young children.

A small cable housing is attached to the rear of the units 1 and 15. The cable housing 9 is now situated at the rear of the units 1 and 15 allowing for either a single or dual cable attachment to accommodate the lower profile unit
