Description
Technical Field
The present invention relates to devices used for self protection and, more particularly, to devices used for self protection that are mountable to the arm of a user and which have a receiving structure for holding a liquid repellant canister.
Background Art
Joggers and other persons participating in solitary physical activities outdoors often find themselves the victims of violent crimes such as rape. In an effort to protect themselves, joggers often carry liquid repellant canisters containing a liquid repellant, such as mace, which, when sprayed in an attacker's face, will disable the attacker. Although carrying a liquid repellant can be a safe, effective form of self protection, attackers often attack with little or no warning and the victim is unable to retrieve the repellant canister, direct the nozzle of the repellant canister in the direction of the attacker, and discharge the repellant in time to defend themselves. It would be a benefit, therefore, to have a device, which automatically directed the nozzle of the repellant canister in the direction of the attacker through the normal defensive reflex of putting one's hands up toward one's face. It would be a further benefit if the device allowed the user to discharge the repellant with the use of one hand.
General Summary Discussion of Invention
It is thus an object of the invention to provide a safety device that holds a canister of liquid repellant in a manner such that a quantity of the repellant may be discharged from the canister while supported by the safety device.
It is a further object of the invention to provide a safety device that directs the nozzle of a liquid repellant canister in the direction of an attacker when a user reflexively puts his/her hands up towards his/her face.
It is a still further object of the invention to provide a safety device that has storage space for carrying personal items such as money and identification.
Accordingly, a safety device for holding a canister of the type containing a supply of liquid repellant and having a nozzle including an orifice through which the liquid repellant is discharged in a predetermined direction with respect to the nozzle orifice, is provided.
