OF THE INVENTION

1. Field of the Invention

The present invention relates to weapons of self defense and particularly to a cane or staff for protecting a user, including a cane or staff body, a stinger operatively connected to the cane or staff body and selectively extending from the cane or staff body, circuitry operatively connected to the stinger, and a trigger operatively connected to the cane or staff body, the circuitry, and the stinger, and selectively extending and operating the stinger.

2. Description of Related Art including Information Disclosed under 37 CFR 1.97 and 1.98

Personal safety is becoming an increasing problem with high crime rates and many streets unsafe. With elderly people the problem is even more severe, since they are viewed as easy prey to criminals because of their lack of dexterity and strength. In remote areas people hiking face dangers from wild animals. The prior art teaches various electric shock self-defense devices, but none which adequately address these problems.

U.S. Pat. No. 4,242,715, issued Dec. 12, 1980 to Laird, is for a self-defense apparatus including a battery-powered source of high voltage arranged in an insulated housing and a finger probe device which is strapped to one finger of one hand of the user and is electrically connected to the source of high voltage. The finger probe device includes a layer of electrical insulation disposed between the finger and two metal prongs which protrude outwardly adjacent the distal end of the finger. One prong couples to the hot side of the source of high voltage and the other prong couples to the ground side of the source of high voltage. A two conductor cable connects the two prongs to the source of high voltage and when both prongs are placed in contact with an electrically conductive surface, they deliver in excess of 1,200 volts.

U.S. Pat. No. 5,839,461, issued Nov. 24, 1998 to Lambeth, Jr., puts forth a protective apparatus for walkers, hikers, and others incorporating a section containing a switchable combination alarm and incapacitating defensive fluid and incorporating a socket for attachment of a camera or lanyard, a storage section, a battery and electrical alarm section incorporating a socket for attachment of an optional walking stick and in a second variation a handle for use as part of a walking cane and in a third variation, an electrical prodding device in place of the storage section and contact points for the electrical prodding device extending from the battery and alarm section.

U.S. Pat. No. 5,986,872, issued Nov. 16, 1999 to Chaput, describes a personal accessory comprising a multi-component electric stunning umbrella which can be carried as a personal accessory without attracting attention, which can be used as a conventional umbrella, and which can also be used for self defense. The stunning umbrella proves a stunning but non-lethal electrical shock when used for self defense and can also be used as a baton or striking implement.

U.S. Pat. No. 6,091,597, issued Jul. 18, 2000 to Lin, is for an improved structure of an electric shock device including a handle, and a plurality of retractable rod portions. The handle has an interior accommodating therein a high voltage generator and a battery unit. The handle further has a control switch at a lower rim thereof. The retractable rod portions are arranged and assembled in order of size, and equipped with a retractable function by utilizing springs and retaining rods disposed therein. The rod portions are made of insulating materials and respectively provided with parallel positive and negative electrode plates on both sides thereof. The electrode plates nearest to the handle are connected to positive and negative terminals of the high voltage generator so as to supply the rod portions with the required high voltages. The permittivity of dielectrics on the rod portions that have different diameters is caused to be equivalent so that the conductance conditions of the rod portions are the same, and the rod portions can all generate electric arcs.

U.S. Pat. No. 6,643,114, issued Nov. 4, 2003 to Stethem, discloses a personal defense device including an electrical stun circuit and electrodes with a structure adapted for use as an impact weapon as well, and further including a radially disposed flashlight or signal light therewith. The electrical circuitry for the stun apparatus is formed of flexible circuit material with dual circuit paths between each component, for reliability and resistance to damage due to impact forces incurred when the device is used as an impact weapon. A second, normally closed interrupter switch is provided for the stun circuit, with the user of the present device being required to hold the interrupter switch in order to keep the stun circuitry from operating when the master switch is turned on. The end opposite the handle includes a series of impact ribs with cutting blades removably installable thereon, to produce shallow (non-life threatening) cuts in an assailant during an attack.

U.S. Pat. No. 6,745,786, issued Jun. 8, 2004 to Davis, provides a walking aid with supplementary features that are communicatively coupled to an integrated timepiece. The combination of the timepiece's intelligent circuitry and memory storage can increase the functionality of the supplementary features integrated therein. The timepiece can also record the use of the supplementary features for later use by the user.

U.S. Pat. No. 6,963,480, issued Nov. 8, 2005 to Eccles, shows a high voltage stun device, unique in the sword-like configuration of its fully retractable, yet non-injurious, “blade,” and its ability to deliver the pulse along the length of the “blade” as well as at the tip to a target at a distance far beyond arm's length. Stun batons, even retractable ones, have none of the preferred properties satisfied by the invention, including superior length of shocking surface, superior weighting and flexibility of the shocking surface, and simplicity of maintenance and repair. The “blade” of the invention is capable of expanding to a superior length that can keep a subject at a good defensive distance, yet be effective and retracted if he manages to get in close. With a moderation of the centrifugal force applied during blade deployment, the invention can be made to emulate a shorter sword, a long sword, and all lengths between. Further, the balance and dimensions of the device allow for fencing techniques to be utilized, while being portable and concealable unlike a traditional, fixed blade sword.

What is needed is a cane or staff for protecting a user, including a cane or staff body, a stinger operatively connected to the cane or staff body and selectively extending from the cane or staff body, circuitry operatively connected to the stinger, and a trigger operatively connected to the cane or staff body, the circuitry, and the stinger, and selectively extending and operating the stinger so that an elderly person normally carrying a cane has a ready weapon of self defense against criminals involved in street crimes and hikers normally carrying walking sticks or staffs have a ready means to defend themselves against wild animals.
