The invention described herein relates to the fields of self-defense and personal protection tools. The present invention is compact, concealable, and easy to use. The present invention allows a user to strike quickly, repeatedly, and from a distance to repel would be attackers. The tensioning mechanism of the present invention allows the user to increase or decrease the flexibility of the striking portion of the tool based on the user's preferences. The present invention can be carried in a multitude of discreet locations, and is a non-lethal defensive option. This tool can be customized in length per user size and preference. The tool can also utilize various clips for additional attachments, and options for attachments to a multitude of locations, on or off the body. The present invention could be utilized in other fields such as law enforcement, or military, where carrying hand-held, non-lethal, self-defense tools are necessary.
Various examples of hand held self-defense tools exist in the prior art. For example, batons are often carried by law enforcement personnel. Generally, a baton is constructed in one piece, of a rigid material such as wood, or a metal alloy. A baton can be unwieldy to use, and require specific training for use. The weight of a baton can be prohibitive for smaller users who lack the strength to effectively use the baton. A one-piece baton is not a practical means for personal self-defense since such tools cannot be carried easily and discreetly.
Telescoping batons can be carried more discreetly; however, the telescoping feature of such batons can be prone to malfunction, and material fatigue. Furthermore, deploying a telescoping baton requires the user to wield the baton, and deploy the telescoping portion of the baton before it can be used effectively. Lastly, telescoping batons, in their deployed state are not adjustable as to their rigidity.
Spring whips utilize interconnected lengths of springs to form the striking portion of the tool. Such a design provides for some flexibility in the striking portion of the tool. However, like a baton, no means to adjust the rigidity of the tool exists. Furthermore, spring whips and telescoping varieties of spring whips have the same problems generally associated with batons, which have been described above.
Due to the issues discussed above, there is a need for an improved, customizable, more discreet, and easy to use self-defense tool. One object of the present invention is to provide a self-defense tool that is light-weight and easy to utilize. Another object of the present invention is to provide a self-defense tool with a tensioning mechanism that can increase or decrease the stiffness of the striking portion of the tool. Another object of the present invention is to provide a self-defense tool that can be discreetly carried in a variety of positions on the body. Yet another object of the present invention is to provide a self-defense tool that can be quickly deployed without reliance on telescoping mechanisms. Another object of the present invention is to provide a self-defense tool that has interchangeable striking ends. Yet another object of the present invention is to provide a self-defense tool, with customizable attachment means and additional utility modifications available.
The subject invention solves the problems outlined above. The subject invention is a composite whip with adjustable tensioning, which can be utilized by anyone for self-defense. The simple and lightweight design of the subject invention allows anyone to deliver a defensive strike to a would-be attacker simply by swinging their arm or wrist while grasping the handle of the subject invention.
One novel feature of the subject invention is the tensioning mechanism, which can be utilized to make the striking portion of the composite whip more, or less flexible based upon the user's preference and method of carry. The design of the subject invention allows it to be carried discreetly on various parts of the body and drawn extremely quickly to fend off would be attackers. For example, the subject invention can be slid inside of clothing and clipped to the waistline of a pair of pants. Or, tension of the subject invention can be decreased, and it can be threaded through belt loops to conform to the user's waist contour, and clipped onto a belt loop. When carried in this manner, the user only needs to grasp the handle and draw the tool for immediate use. No retrieval from a handbag, telescoping, or special skills are required for the tool to be utilized for self-defense.
The tensioning mechanism will also affect the reactiveness and striking force of the composite whip. As more tension is applied, the striking portion of the composite whip becomes stiffer. A stiffer striking portion will have a faster reaction speed and deliver more force to the object being struck. Conversely, a more flexible striking portion will be less reactive, and deliver less force to the object being struck.
The subject invention is comprised of a proximal handle, which can be constructed of a multitude of materials. The handle of the embodiment described herein is constructed of high impact nylon. The handle is gripped by the user to swing the composite whip. An outer support tube extends distally from the interior of the handle casing, which provides support to the proximal portion of the whip outer sleeve. Both the outer support tube and whip outer sleeve can be constructed of any flexible material. The outer support tube and whip outer sleeve of the embodiment described herein are constructed of flexible vinyl.
At the distal striking end of the whip outer sleeve is a distal tensioning sleeve. The distal tensioning sleeve can be constructed with interior threads, or other features which can accept interchangeable striking tips. The standard distal tensioning sleeve does not contain interior threading. The distal tensioning sleeve is generally constructed of stainless steel; however, any multitude of materials could be used to construct the distal tensioning feature of the present invention. The distal tensioning sleeve of the present invention provides a distal tensioning anchor by holding the distal weld ball of the inner cable. The inner cable can be any material suitable to withstand significant bending forces while under tension. The inner cable of the embodiment described herein, is a stainless-steel cable.
During assembly, the inner cable is inserted into the distal tensioning sleeve and whip outer sleeve, which have been pre-inserted into the outer support tube. The distal weld ball is then seated within the distal tensioning sleeve. Once the distal weld ball is seated within the distal tensioning sleeve, the tensioning mechanism is then assembled. The tensioning mechanism provides the proximal tensioning anchor, and means to adjust the stiffness of the striking portion of the present invention. The tensioning mechanism can be made of any material capable of withstanding significant tensile force without deformation. The means of providing the proximal and distal tensioning anchors can be accomplished in a multitude of ways including but not limited to crimping, gluing, pinning, staking, or spot welding. The means of providing the tensioning mechanism can also be accomplished in a multitude of ways including but not limited to utilization of springs, levers, binding devices, or notches.
The tensioning mechanism described in one of the embodiments herein is constructed of stainless-steel. To assemble the tensioning mechanism, a threaded inner sleeve is slid onto the proximal end of the inner cable. The distal end of the threaded inner sleeve butts up against the proximal end of the whip outer sleeve. The threaded inner sleeve then accepts a threaded outer sleeve which is used to increase or decrease tension of the inner cable.
Once the threaded outer sleeve is fully rotated on to the threaded inner sleeve, a proximal weld ball is created by TIG welding the proximal end of the inner cable. The embodiment described herein utilizes TIG welding of the stainless-steel inner cable to create the proximal and distal weld balls which create the anchors necessary to allow tensioning of the inner cable.
In this embodiment, tension of the inner cable is created by rotating the outer threaded sleeve on the threaded inner sleeve as shown in
It should be noted that the preferred embodiments include the tensioning mechanism described herein; however, the tensioning mechanism could be excluded in other embodiments. In such embodiments, the tensioning mechanism could be replaced by a proximal tensioning sleeve, in which the proximal weld ball of the inner cable would be seated. Such an embodiment would exhibit all the features discussed above, except for the ability to adjust the tension of the inner cable, and thus the stiffness of the striking portion of the composite whip.
In another preferred embodiment, the tensioning mechanism is comprised of a stainless-steel spring, which automatically tensions the whip portion of the invention when the whip is bent, thus increasing the reaction force and speed of the whip when the whip returns back to its straight position. Tensioning provided by said stainless-steel spring, also allows increased flexibility of the inner cable. Providing for increased flexibility and automatic tensioning of the inner cable allows the invention to be configured for discreet storage, yet maintain the invention's fast deployment characteristics.
The proximal end of the outer sleeve and tensioning mechanism seat within a molded groove of each half of the handle. The halves of the handle are secured together by a plurality of screws and corresponding nuts, which hold the proximal end and tensioning mechanism securely in place. The handle, also features a striking end at the proximal end of the handle. Accessory holes and/or clips can be utilized on the handle for various attachment means of the subject invention to essentially any conceivable attachment point. The handle portion of the subject invention could also be modified to contain other utility features such as knives, sprays, lights or electric shock mechanisms.
In another preferred embodiment, the handle is further comprised of a quick release mechanism, which allows the whip/tensioning mechanism to be disengaged and removed from the handle. Quick release capability of the whip/tensioning mechanism allows the user to quickly adjust the tension of the inner cable without taking the handle apart. Said quick release mechanism also allows the user to quickly switch implements for use with the handle. For example, the user could remove the composite whip, and install a ridged club implement, or knife, hatchet, etc. depending on situational need.
Regarding the embodiments explained in detail, the figures and specifications should be understood as illustrations only, and are not intended to limit the invention in its scope. Also, in describing the embodiments, specific terminology may be used, but it should be understood that specific terms include all technical equivalents that operate in similar manners to accomplish similar purposes.
With reference to the drawings, a preferred embodiment of the composite whip is illustrated in the attached drawings. A preferred embodiment of the composite whip is depicted in
At the distal striking end of the whip outer sleeve 3 is a distal tensioning sleeve 4, which can be threaded to accept interchangeable striking tips 5. The standard distal tensioning sleeve 4 is unthreaded. The distal tensioning sleeve 4 holds the distal weld ball 6 of the inner cable 7. During assembly, the inner cable 7 is inserted into the distal tensioning sleeve 4 and whip outer sleeve, which have been pre-inserted into the outer support tube 2. The distal weld ball 6 is then seated within the distal tensioning sleeve 4. Once the distal weld ball 6 is seated within the distal tensioning sleeve 4, the tensioning mechanism 16 is then assembled. To assemble the tensioning mechanism 16, a threaded inner sleeve 8 is slid onto the proximal end of the inner cable 7. The distal end of the threaded inner sleeve 9 butts up against the proximal end of the whip outer sleeve 10. The threaded inner sleeve 8 then accepts a threaded outer sleeve 11 which is used to increase or decrease tension of the inner cable 7.
Once the threaded outer sleeve 11 is fully rotated on to the threaded inner sleeve 8, a proximal weld ball 12 is created by TIG welding the proximal end of the inner cable 7. Tension of the inner cable 7 is created by counter-rotating the outer threaded sleeve 11 on the threaded inner sleeve 8 as shown in
The proximal end 15 and tensioning mechanism 16 of the composite whip 14 seat within a molded groove 17 of each half of the handle 1. The halves of the handle 1 are secured together by a plurality of screws 18 and corresponding nuts 19, which hold the proximal end 15 and tensioning mechanism 16 securely in place. The handle 1, also features a striking end 20 at the proximal end of the handle 1.
In another preferred embodiment, the tensioning mechanism is comprised of a stainless-steel spring 22, which automatically tensions the whip portion of the invention when the whip is bent, thus increasing the reaction force and speed of the whip when the whip returns back to its straight position. Once the distal weld ball 6 is seated within the distal tensioning sleeve 4, the stainless-steel spring 22 tensioning mechanism is then assembled. To assemble the stainless-steel spring 22 tensioning mechanism, a stainless-steel washer 23 is slid onto the proximal end of the inner cable 7. Said stainless-steel spring 22 is then slid onto the proximal end of the inner cable 7, and compressed slightly against the stainless-steel washer 23, which butts up against the proximal end of the whip outer sleeve 10. A proximal stainless-steel washer 24 is then slid onto the proximal end of the inner cable 7. A proximal weld ball 12 is then created by TIG welding the proximal end of the inner cable 7. Tension of the inner cable 7 is automatically created by the stainless-steel spring simultaneously pushing against the proximal end of the whip outer sleeve 10, and the proximal weld ball 12, which results in a stretching force applied to the length of the inner cable 7 as already described above.
A novel feature of this embodiment is the automatic tensioning provided by said stainless-steel spring 22, which allows increased flexibility of the inner cable 7. Providing for increased flexibility and automatic tensioning of the inner cable 7 allows the invention to be configured for discreet storage as shown in
In another preferred embodiment, the invention is comprised of quick release means. This embodiment is comprised of a quick release slide 25, which allows the whip and tensioning mechanism 16 to be disengaged and removed from the handle 1. Quick release capability of the whip/tensioning mechanism 16 allows the user to quickly adjust the tension of the inner cable 7 without taking the handle 1 apart. To disengage the whip/tensioning mechanism 16 from the handle 1, the user slides the quick release slide 25 back towards the proximal end of the handle 1. Said quick release slide 25 is further comprised of a molded quick release ramp 26, which slides back when the user slides the quick release slide 25 back. When slid back, the quick release ramp 26 elevates a quick release spring 27. When the quick release spring 27 is in the elevated position, the user can pull the whip/tensioning mechanism 16 from the handle 1.
Once the whip/tensioning mechanism 16 is disengaged from the handle 1, the tension of the inner cable 7 can be easily adjusted to user preference by rotating the outer threaded sleeve 11 until the desired amount of stiffness of the composite whip 14 is achieved. The user then simply slides back the quick release slide 25, re-inserts the whip/tensioning mechanism 16 into the handle, and releases the quick release slide 25, which drops the quick release spring 27 into the engaged position as shown in
Said quick release means also allows the user to quickly switch interchangeable implements for use with the handle 1. For example, the user could remove the composite whip 14, and install a ridged club implement, knife, hatchet, etc. depending on situational need. Such interchangeable implements would be comprised of a universal shaft with a corresponding recess to be engaged and disengaged by the quick release spring 25.
In yet another embodiment of the current invention, a combination of features herein described can be utilized to achieve external adjustable tensioning means of the composite whip 14, and allow for discreet storage. For example, a slide button similar to the quick release slide 25 could be configured to further comprise a catch, which engages the tensioning means of the device, which would allow the user to increase and decrease tension of the composite whip 14 by positioning the slide at predetermined tensioning positions. Specifically, the slide catch would engage the distal end of the stainless-steel spring 22. When the user slides the slide button back, the stain-less spring will be compressed and will increase the longitudinal tension on the inner cable 7, thus increasing the overall stiffness of the composite whip 14. Said slide button could then be locked in predetermined tensioning positions comprised of grooves or other means to lock the slide and catch mechanism in the desired tensioned position. To de-tension the device, the user would simply release the slide button from the locked position. In the de-tensioned state, the user would then be able to discreetly store the device as already described herein, and shown in
