BACKGROUND 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.

BRIEF SUMMARY OF THE INVENTION

In FIGS. 1-12, a combination ambulatory assistance and electrical shock defensive device comprises a cane embodiment of the device 10A in FIGS. 1 and 2, a walking staff embodiment of the device 10B in FIG. 3 with the stinger 30B extended, and a hand stick embodiment of the device 10C in FIG. 4.

In FIGS. 1-3, an elongated ambulatory assist shaft 10A and 10B comprises a rigid body 20A and 20B having a top hand grip 12A and 12B, a hollow interior space along at least a portion of the length thereof, a bottom ground contacting portion 29, and a lower exterior opening communicating with the hollow interior space 22.

In FIGS. 1-4, a stinger 30A, 30B, and 30C is operatively connected to the rigid body 20A, 20B, and 20C of the cane 10A, walking staff 10B, and hand stick 10C respectively, within the hollow interior space of the tubular shaft 20A, 20B and 20C and selectively extending from the rigid body through the lower exterior opening 22, as shown in FIG. 2.

In FIGS. 9 and 10, the stinger 30 comprises a highly conductive carbon composite material rod 30 with an end rim 32, which may be the head of a bolt for engaging with the retaining hooks 12 which cooperate with the retainer collar 14 and engage release hooks 9 attached to the spring sleeve 8 so that when the retaining hooks 12 are disengaged the springs 11 and 14 launch the stinger 30 out of the main tubular shaft 20A, 20B or 20C of the cane 10A, walking staff 10B, and hand held stick 10C, respectively, of FIGS. 1-4, so that the electrically charged stinger 30 can contact an assailant and disable the assailant with an electric shock 31.

In FIGS. 1, 5, and 6, circuitry 4, 5, and 6 operatively connected to the stinger 30 comprises batteries 6 and voltage amplifiers 4 and 5 for boosting the electrical charge to produce a desired level of electrical shock 31 produced by the stinger 30, as shown in FIG. 2.

In FIGS. 9-12, a trigger mechanism operatively connected to the rigid body 20A, 20B, and 20C (as shown in FIGS. 1-4), the circuitry 4, 5, and 6, and the stinger 30, causes the stinger to be selectively extended (as shown in FIG. 2) and operates the stinger, the circuitry providing an electrical charge to the stinger 30 to create an electrical shock 31 to a would be aggressor to disable the aggressor and defend the user. In FIGS. 11 and 12, the trigger mechanism comprises a push button 23 or a button to be otherwise manipulated positioned in close proximity to or on the hand grip 21A to enable a user to manipulate the button 23 attached by springs 22A and 22B to the hand grip area to move a tapered control rod 24 or other mechanisms to open and close a stinger holding device, such as the stinger holding plate 25. The stinger holding plate 25 pivots 15 open to release the stinger 30 when the button 23 is pressed and pivots closed to secure the neck 33 of the stinger 30 in the split hole 26 with the stinger rim 32 held above the plate 25. Alternately in FIGS. 1, 9, and 10, the button 23 manipulates hooks 9 engaging pivoting spring latches 12 around a retainer ring 16 to alternately release and retain the stinger rim 32 normally held within the latches 12 until it is desired to release the stinger 30. The springs 11 and 14 send the stinger 30 partially out of the shaft 20A guided by stinger guides 27 and 27A which include a stinger guide and stop 27A which prevents the stinger from completely leaving the shaft 20A, allowing it to extend out of the shaft at least two feet for the cane 10A and the staff 10B.

FIGS. 5 and 11 show the threaded portion 2 of the hand grip 21 enabling the tubular shaft 20 to tighten securing onto the hand grip. A collar 7 sits between the two fitted devices when secured together.

In FIGS. 1 and 5-6, the power source comprises at least one electrically amplified rechargeable battery 6. A series of rechargeable batteries 6 may also provide a power source attached to the rigid body for providing the power to the circuitry and the stinger.

FIG. 5 shows the circuitry including voltage amplifiers 4, 5, and 6 is adjustable by using the charge intensity control knob 33 to create a desired level of electrical charge 31 in the stinger 30 so that the stinger can provide an electrical shock to produce a result ranging from causing a slight jolt to causing temporary paralysis and unconsciousness.

IN FIGS. 9 and 10, the device further comprises at least one and preferably two springs 11 and 14 between the stinger 30 and the rigid body 20A for forcing the stinger out of the rigid body, the circuitry releasing a stop so that the spring springs the stinger 30 out of the rigid body.

FIG. 2 shows the stinger 30A extended at least two feet out of the rigid body.

In FIG. 2, a wrist strap 28 is attached adjacent to the hand grasping portion of the hand grip 21A to cinch up tight around a wrist of a user to keep people from pulling the device from a hand of the user and keep it in the possession of the person holding it and using it. The strap 28 comprises an inner core sufficiently strong that it could only be cut with wire cutters and an outer covering of pliable leather like material.

In FIGS. 5 and 6, a location finding chip 13 is attached within the interior of the hand grip 21 to find the device if it is forgotten, lost, or stolen.

In FIGS. 2, 5, and 10, a warning light 35 indicates when the battery needs to be charged up and when there is a full charge in the battery.

In use, when a user is assaulted by a person or animal, the user can instantly point the electrical shock walking stick device 10 at the assailant and press the button 23 to extend the stinger 30 and shock the assailant to temporarily disable the assailant so that the user can escape or disarm or further disable the assailant.

When the electrical shock walking stick device of the present invention is misplaced or lost or stolen, a user could go to a computer or a location finding device and see the exact location of the device via the location finding chip 13 and go and get it or have the authorities retrieve it. The device could also have an owner's license number stamped on it.
