Abstract

Provided herein is a personal security device in the form of a wrist band, which is intended to be worn about a limb of a wearer, such as a wrist. A device according to the invention is adapted to be secured in locked fashion about its wearer, and includes an alarm means which may be activated by the user at any desired time, to emit a high intensity audible alarm for a pre-determined amount of time to attract attention of other persons in the immediate vicinity for cases where the wearer perceives they are being approached by a would-be offender or attacker. According to a preferred embodiment, a radio frequency transmission is commenced simultaneously with the sounding of the audible alarm, in order to enable a second person who is possessed of a unit capable of receiving the transmitted signal to track and locate the person wearing the device of the invention.

Claims

1. ) A personal security wrist band that is designed to fit about a limb of the user which comprises:

a) a band portion having an outer surface and a hollow interior space adapted to house electrical and mechanical components;

b) a push-button switch disposed on said outer surface;

c) a battery compartment adapted to receive electrical storage batteries disposed within said hollow interior space;

d) a sound transducer disposed within said hollow interior space sufficiently to enable sonic energy emitted by said transducer to be broadcast into the area about said wrist band;

e) a circuit means in sufficient electrical contact with said switch, at least one battery disposed within said battery storage compartment, and said transducer for enabling a sound to be emitted when said switch is depressed.

2. ) A personal security wrist band according to claim 1 wherein said band portion is comprised of a first semi-circular half portion having a first end portion and a second end portion;

and a second semi-circular half portion, having a first end portion and a second end portion, wherein said first end portion of said first semi-circular half portion and said first end portion of said second semi-circular half portion are pivotally connected to one another by a hinge means.

3. ) A wrist band according to claim 2 wherein said second end portion of said first semi-circular half portion includes a notched tang portion.

4. ) A wrist band according to claim 3 wherein said second end portion of said second semi-circular half portion includes a notched tang receiver, which receiver is adapted to receive said notched tang portion.

5. ) A wrist band according to claim 4 further comprising a locking means disposed within said hollow interior space of said second semi-circular half portion that is located in sufficient proximity to said notched tang receiver to provide selective locking of said notched tang portion within said notched tang receiver.

6. ) A wrist band according to claim 5 and further comprising a keyhole disposed on the outer surface portion of said second semi-circular half portion that is adapted to receive a key for actuating said locking means.

7. ) A wrist band according to claim 1 wherein said circuit means includes a delay sufficient to cause a sound to be emitted from said transducer for any time period in the range of between about 1 and 20 minutes and subsequently causes said sound to cease until said switch is again depressed.

8. ) A wrist band according to claim 1 further having a protective means disposed on said surface portion which protective means comprises a wire mesh, wherein said wire mesh is disposed about the portion of said transducer which emits sound, so as to protect said transducer from damage from impacts, droppage, and normal wear and tear.

9. ) A wrist band according to claim 1 wherein said circuit means includes a transmitting means for transmitting a radio-frequency signal.

10. ) A wrist band according to claim 9 wherein said transmitting means transmits a radio frequency signal after said switch is depressed.

11. ) A system for locating a person comprising:

a) a wrist band according to claim 10;

b) a signal-receiving means,

wherein said signal-receiving means includes at least one indicator means selected from the group consisting of;

a light emitting means and a sound emitting means, and wherein said indicator means increases in its intensity as the distance between said wrist band and said signal-receiving means decreases.

12. ) A personal security wrist band that is designed to fit about a limb of the user which comprises:

a) a band portion made from a flexible material having a first end portion and a second end portion, and surface portion;

b) a push-button switch disposed on said outer surface;

c) a battery compartment adapted to receive electrical storage batteries, disposed between said first end portion and said second end portion;

d) a sound transducer disposed between said first end portion and said second end portion;

e) a circuit means in sufficient electrical contact with said switch, at least one battery disposed within said battery storage compartment, and said transducer for enabling a sound to be emitted when said switch is depressed.

13. ) A wrist band according to claim 12 wherein said first end portion of said band includes a locking tang portion.

14. ) A wrist band according to claim 13 wherein said second end portion of said band includes a locking tang receiver, which receiver is adapted to receive said locking tang portion.

15. ) A wrist band according to claim 14 wherein said receiver includes a locking means for locking said locking tang in a fixed position inside said receiver, wherein said locking means includes a keyhole.

16. ) A wrist band according to claim 12 wherein said circuit means includes a delay sufficient to cause a sound to be emitted from said transducer for any time period in the range of between about 1 and 20 minutes and subsequently causes said sound to cease until said switch is again depressed.

17. ) A wrist band according to claim 12 further having a a wire mesh disposed about the portion of said transducer which emits sound, so as to protect said transducer from damage from impacts, droppage, and normal wear and tear.

18. ) A wrist band according to claim 12 wherein said circuit means includes a transmitting means.

19. ) A wrist band according to claim 18 wherein said transmitting means transmits a radio frequency signal after said switch is depressed.

20. ) A system for locating a person comprising:

a) a wrist band according to claim 19;

b) a signal-receiving means,

wherein said signal-receiving means includes at least one indicator means selected from the group consisting of;

a light emitting means and a sound emitting means, and wherein said indicator means increases in its intensity as the distance between said wrist band and said signal-receiving means decreases.
