This invention relates to multi-purpose tools in general, and more particularly to multi-purpose tools for illumination, self-defense and glass-breaking.
In many circumstances a person may need illumination, such as at night, or when in a dark building, etc. In this case, a flashlight or the like may be useful.
And in many circumstances a person may need self-defense capabilities, such as to fend off an assailant. In this case, a pepper spray unit may be extremely important.
And in certain circumstances, a person may need glass-breaking capabilities, such as when the person needs to quickly exit a motor vehicle. In this case, a glass-breaking tool may be critical.
And in some circumstances, a person may need some combination of one or more of illumination, self-defense capabilities and/or glass-breaking capabilities. In such a situation, the need to locate and handle two or more separate, single-purpose devices can be a severe hindrance to rapidly achieving the desired illumination, self-defense and glass-breaking capability. This is especially true in emergency situations where time is of the essence, and where fumbling with multiple, single-purpose devices can hinder rapid access to illumination, self-defense and glass-breaking capability.
Thus there is a need for a new multi-purpose illumination, self-defense and glass-breaking tool which can provide, in a single device, illumination, self-defense capability and/or glass-breaking capability.
The present invention comprises the provision and use of a new multi-purpose illumination, self-defense and glass-breaking tool which can provide, in a single device, illumination, self-defense capability and glass-breaking capability.
Significantly, the user is able to wield and operate the multi-purpose tool with one hand without the need to actively grip the multi-purpose tool with their fingers, leaving their fingers free to grab keys, open a door, hold a gun, etc.
In one form of the invention, there is provided a multi-purpose illumination, self-defense and glass-breaking tool, the tool comprising:
a tool body;
a handle projecting from the tool body;
a flashlight carried by the tool body;
a pepper spray unit carried by the tool body; and
a glass breaker carried by the handle.
In another form of the invention, there is provided a method for providing at least one of illumination, pepper spray dispensing and glass-breaking capability, the method comprising:
providing a multi-purpose illumination, self-defense and glass-breaking tool, the tool comprising:
engaging the handle of the tool with the fingers of a user; and
taking at least one of the following actions:
These and other objects and features of the present invention will be more fully disclosed or rendered obvious by the following detailed description of the preferred embodiments of the invention, which is to be considered together with the accompanying drawings wherein like numbers refer to like parts, and further wherein:
The present invention comprises the provision and use of a novel multi-purpose illumination, self-defense and glass-breaking tool 5 shown in
Looking first at
More particularly, handle 10 is formed with a “U” shape which projects from the bottom of tool body 15. The “U” shape of handle 10 is formed by a front leg 35 and a rear leg 40, both of which project downward from the bottom of tool body 15, and a closed bottom connector 45 which extends between the bottom portions of front leg 35 and rear leg 40. The “U” shape of handle 10 in turn creates an interior space 50 which is sized to receive the four fingers of a user's hand, with the heel of the hand resting against rear leg 40. In one form of the invention, interior space 50 is sized to closely receive the four fingers of a user's hand. In order to improve the fit and prevent slippage of the user's fingers within interior space 50, grooves 55 may be provided on the inward-facing surface of front leg 35 in order to closely contour-mate front leg 35 with the four fingers of the user's hand. Significantly, with such a construction, multi-purpose illumination, self-defense and glass-breaking tool 5 can be maintained on the user's hand solely by the fit of handle 10 around the user's fingers (i.e., the user does not need to actively grip rear leg 40 of handle 10 with the four fingers of his/her hand). It will be appreciated that, without the need for the user to actively grip rear leg 40 of handle 10 with the four fingers of his/her hand, the four fingers of the user's hand are free to grab keys, open a door, hold a gun, etc., while the user wields multi-purpose illumination, self-defense and glass-breaking tool 5.
On the bottom side of closed bottom connector 45, there is provided a glass breaker 20 for use in breaking glass, e.g., vehicle windows in the case of an emergency. Glass breaker 20 comprises a cone-shaped point 60 extending from a threaded body 65. Glass breaker 20 may comprise a ½-13×¾″ cone point set screw sold by McMaster Carr. Threaded body 65 is preferably completely received by closed bottom connector 45 of handle 10 such that only point 60 protrudes outward from closed bottom connector 45. Point 60 provides a small surface area onto which the force generated from a user swinging multi-purpose illumination, self-defense and glass-breaking tool 5 can be concentrated, thereby allowing the user to more readily break glass, e.g., a car window in the case of an emergency. To that end, glass breaker 20 is preferably made of a hard and strong material such as alloy steel, and handle 10 (and tool body 15) are preferably made of a durable material such as onyx nylon which can withstand the forces generated during the use of glass breaker 20 of multi-purpose illumination, self-defense and glass-breaking tool 5.
In one form of the invention, a latch 70 is provided on rear leg 40 of handle 10 so that handle 10 can act as a carabiner for clipping or hanging multi-purpose illumination, self-defense and glass-breaking tool 5 to another object (e.g., to a belt or to a loop provided on an article of clothing), or for clipping or hanging another object (e.g., a whistle on a short lanyard) to multi-purpose illumination, self-defense and glass-breaking tool 5. More specifically, rear leg 40 of handle 10 may comprise a bottom section 75 and a top section 80, with an arm 85 extending therebetween. One end of arm 85 is pivotally mounted to bottom section 75 of rear leg 40 by a spring pin 90 (e.g., a 3/16×⅞ spring pin sold by McMaster Carr) such that arm 85 is able to swing outward from top section 80, opening the “U” shape of handle 10 so that the interior space 50 of the handle can be accessed through latch 70 of rear leg 40, and then spring back into contact with top section 80 so as to restore the “U” shape of handle 10 (i.e., so that interior space 50 of the handle can no longer be accessed through latch 70 of rear leg 40). To help keep the “U” shape of handle 10 closed, a selective closure means 86 (e.g., NEO 35 (NdFeB) magnets sold by McMaster Carr) may be provided on top section 80 of rear leg 40 and the free end of arm 85.
Thus, where, for example, multi-purpose illumination, self-defense and glass-breaking tool 5 is to be clipped to the belt of a user, latch 70 is opened, handle 10 is moved so that the belt is passed through open latch 70, and then latch 70 is closed so as to securely clip multi-purpose illumination, self-defense and glass-breaking tool 5 to the belt of the user. When multi-purpose illumination, self-defense and glass-breaking tool 5 is thereafter to be used, latch 70 is opened, handle 10 is moved so that the belt is passed through open latch 70, latch 70 is closed so as to restore the normal “U” shape of handle 10, and then the fingers of the user are passed through interior space 50 so that multi-purpose illumination, self-defense and glass-breaking tool 5 is mounted to the fingers of the user. Furthermore, where, for example, multi-purpose illumination, self-defense and glass-breaking tool 5 is to have a whistle (on a short lanyard) clipped to handle 10, latch 70 is opened, the lanyard of the whistle is passed through open latch 70, and then latch 70 is closed so as to securely clip the lanyard of the whistle (and hence securely clip the whistle) to multi-purpose illumination, self-defense and glass-breaking tool 5. When the whistle is to be unclipped from multi-purpose illumination, self-defense and glass-breaking tool 5, latch 70 is opened, the lanyard of the whistle is passed through open latch 70, and latch 70 is closed, so as to restore the normal “U” shape of handle 10.
Looking next at tool body 15, tool body 15 comprises parallel, cylindrical cavities 95 and 100 sized to receive pepper spray unit 25 and flashlight 30, respectively. Cavities 95 and 100 (and therefore pepper spray unit 25 and flashlight 30) extend horizontally through tool body 15 from the front end of tool body 15 to the rear end of tool body 15. With pepper spray unit 25 and flashlight 30 in this orientation, the user is able to easily reach/operate the back ends of both pepper spray unit 25 and flashlight 30 with his/her thumb of the same hand which holds multi-purpose illumination, self-defense and glass-breaking tool 5. Hence, multi-purpose illumination, self-defense and glass-breaking tool 5 can be held and fully operated with one hand.
With respect to pepper spray unit 25, pepper spray unit 25 comprises a replaceable pepper spray canister (e.g., a pepper spray Spitfire Refill Unit sold by Sabre Red, or another pepper spray refill unit available from Sabre Red or another manufacturer) having a front end 105 from which pepper spray fluid is discharged, and a rear end 110 which the user can depress to initiate discharge of pepper spray fluid. Pepper spray unit 25 is loaded, rear end 110 first, into the front end of cavity 95 until pepper spray unit 25 reaches a narrowed opening 115 at the rear of cavity 95. Narrowed opening 115 has a smaller diameter than pepper spray unit 25, whereby to prevent pepper spray unit 25 from sliding out of the rear end of cavity 95. Pepper spray unit 25 is then secured within cavity 95 by screwing a threaded nozzle extender 120 onto the front end of cavity 95.
To initiate discharge of pepper spray fluid from pepper spray unit 25, rear end 110 of pepper spray unit 25 must be pressed toward the remainder of pepper spray unit 25, i.e., rear end 110 must be pushed forward. This is facilitated by a push button 125 extending through narrowed opening 115 of cavity 95. Pressing push button 125 forward against rear end 110 of pepper spray unit 25 causes pepper spray fluid to be discharged out the front of pepper spray unit 25. However, a safety stop 130 is preferably also provided to prevent the user from accidentally discharging pepper spray fluid with an errant press of push button 125. More particularly, safety stop 130 is slidably held within a vertical slot 135 on the rear face of tool body 15 by a pin 140 (e.g., a 4-40×⅜ BH screw sold by McMaster Carr), and is moveable between an “inactive” position (the “up” position in the frame of reference of
With respect to flashlight 30, flashlight 30 comprises a cyclindrical flashlight (e.g., a Redline tactical flashlight sold by NEBO, or another flashlight available from NEBO or another manufacturer) having a front end 145 from which light is emitted and a rear end 150 by which operation of flashlight 30 is controlled (e.g., turning the flashlight on/off, dimming, changing flash patterns, etc. by pushing on a button provided on rear end 150). Flashlight 30 is loaded, rear end 150 first, into the front end of cavity 100 until flashlight 30 is flush, or near flush, to the rear face of tool body 15. Flashlight 30 is then secured within cavity 100 of tool body 15 by two set screws 155 (e.g., two ¼-20×¼ cup point set screws sold by McMaster Carr) which are advanced through the top of tool body 15 and which pinch down on flashlight 30 so as to secure flashlight 30 against movement relative to tool body 15.
In use, when multi-purpose illumination, self-defense and glass-breaking tool 5 is to be used, it is first held by one hand of a user, with the fingers of the user extending into interior space 50 of handle 10. Then, if multi-purpose illumination, self-defense and glass-breaking tool 5 is to be used to break glass (e.g., a car window in the case of an emergency), glass breaker 20 of multi-purpose illumination, self-defense and glass-breaking tool 5 is driven against the glass. Or if multi-purpose illumination, self-defense and glass-breaking tool 5 is to be used for personal defense, safety stop 130 is slid from its “inactive” position down to its “active” position, and then rear end 110 of pepper spray unit 25 is depressed via push button 125 so as to discharge pepper spray fluid from the front end 105 of pepper spray unit 25. Or if multi-purpose illumination, self-defense and glass-breaking tool 5 is to be used for illumination, rear end 150 of flashlight 30 is used to turn the flashlight on so that light is emitted from front end 145 of flashlight 30.
