The field of the present disclosure is in the area of self-defense tools.
Numerous self-defense tools have been used to provide peace-of-mind to the user. Conventional self-defense tools include pepper spray, Tasers, and the like. These tools provide non-lethal means to allow a victim of an attack time to get away from his or her assailant. However, they can be difficult to use in practice. For example, pepper spray is compact and easy to carry, and when used properly, can prove effective at briefly debilitating an assailant. Pepper spray canisters, however, are not conducive to panicked use, as would commonly be expected in a surprise attack. Tasers share similar problems. Weapons such as knives and firearms are too easily used offensively and may be subject to additional regulation. They also present a strong risk of self-injury in a panicked situation. Thus, a need exists for a self-defense tool that is designed for protection, allows safe and effective operation in surprise and/or panicked conditions, and provides for a quick shock or debilitating injury to the assailant to allow the victim to remove themselves from danger.
Disclosed is a self-defense tool having a blade that is designed primarily for self-defense. The design is intended to eliminate intent to kill on the part of the user when used in defense of an attack. The tool cannot easily be used as an offensive weapon. Thus, when used properly, it is geared to take the intent to kill away from user. The tool is designed to hit the pressure points or places of an attacker and give time for the user to make a critical decision to run or defend. The sharpened blade portion has a reverse cut that is intended to cut more as an attacker pulls away than when the sharpened blade portion is thrust forward. The design minimizes the probability of self-injury by the tool, while maximizing the ability to defend the user from the attacker.
In an embodiment, a self-defense tool may include a grip portion that has a central longitudinal axis, and a blade portion associated to the grip portion forming a first angle between 40 and 50 degrees from a perpendicular line extending from the central longitudinal axis. The blade portion may include a blunt outer portion that curves to a tip and a blunt inner portion. The self-defense tool may also include a sharpened portion positioned between the tip and the blunt inner portion, the sharpened portion extends in a straight line that forms a second angle with a horizontal line perpendicular to the central vertical axis of the grip portion, the second angle measuring between 40 and 50 degrees. The sharpened portion may be between 1 inches and 3 inches long, preferably about 2 inches.
In other embodiments, the first angle may be between 45 and 48 degrees, and the second angle may be between 42 and 45 degrees. In other embodiments, the first angle may be between 46 and 47 degrees, and the second angle may be between 43 and 44 degrees. In some embodiments, the first and second angles may be substantially complementary.
Optionally, the grip portion may be capable of being used ambidextrously and is substantially linear and straight. The blunt inner portion may include one or more indents and, in some embodiments, the indents may be smoothly curved in shape. The indents may have a radius of curvature between 0.5 and 1 inches. In some embodiments, the blunt inner portion includes four indents. In some embodiments, three of the indents each may have a radius of curvature between 0.6 and 0.7 inches, and a fourth indent may have a radius of curvature between 0.9 and 1 inches. In some embodiments, the fourth indent is positioned proximate to the sharpened portion.
Optionally, the blade portion and the grip portion may be detachable. The blade portion may be attached to the grip portion at a first end of the grip portion and the grip portion may include a pointed end distal to the first end. The pointed end may have a pyramidal shape and in one embodiment its length may vary from as small as about 20 mm to as large as about 40 mm, more preferably about 25 mm to about 35 mm.
Optionally, the self-defense tool may also include a holster that may be shaped to accommodate the blade portion and completely covers at least the sharpened portion. The holster may include a clip that facilitates attachment to a belt and the clip may be configured to hold the self-defense tool so that the grip portion is in a substantially horizontal position. Alternatively, the clip may be configured to hold the self-defense tool so that the grip portion is held at an angle of between 6 and 10 degrees relative to the clip, and may be held at an angle around 8 degrees.
The various aspects, features and embodiments of the self-defense tool and holster as disclosed herein will be better understood when read in conjunction with the drawings provided. Embodiments are provided in the drawings for the purposes of illustrating aspects, features and/or various embodiments of the self-dense tool and holster, but the claims should not be limited to the precise arrangement, structures, subassemblies, features, embodiments, aspects, and devices shown, and the arrangements, structures, subassemblies, features, embodiments, aspects, and devices shown may be used singularly or in combination with other arrangements, structures, subassemblies, features, embodiments, aspects, and devices. The drawings are not necessarily to scale and are not in any way intended to limit the scope of the claims, but merely are presented to illustrate and describe various embodiments, aspects and features of the self-defense tool and holster to one of ordinary skill in the art.
In the following detailed description, numerous details are set forth in order to provide an understanding of the self-defense tool and holster, and their method of operation and use. However, it will be understood by those skilled in the art that the different and numerous embodiments of the self-defense tool and holster, their method of operation and use may be practiced without these specific details, and the claims and invention should not be limited to the embodiments, subassemblies, or the specified features or details specifically described and shown herein. The description provided herein is directed to one of ordinary skill in the art and in circumstances, well-known methods, procedures, manufacturing techniques, components, and assemblies have not been described in detail so as not to obscure other aspects, or features of the self-defense tool and holster.
Accordingly, it will be understood that the components, aspects, features, elements, and subassemblies of the embodiments, as generally described and illustrated in the figures herein, can be arranged and designed in a variety of different configurations in addition to the described embodiments. It is to be understood that the self-defense tool and holster may be used with many additions, substitutions, or modifications of form, structure, arrangement, proportions, materials, and components, which may be particularly adapted to specific environments and operative requirements without departing from the spirit and scope of the invention. The following descriptions are intended only by way of example, and simply illustrate certain selected embodiments of a self-defense tool and holster. For example, while the self-defense tool and holster are shown and described in examples with particular reference to its use as a self-defense tool to protect against an attack, it should be understood that the self-defense tool and holster, and aspects thereof may have other applications as well. The claims appended hereto will set forth the claimed invention and should be broadly construed to cover a self-defense tool and/or holster, unless otherwise clearly indicated to be more narrowly construed to exclude embodiments, elements and/or features of the self-defense tool and/or holster.
Throughout the present application, reference numbers are used to indicate a generic element, mechanism, assembly, or feature of the self-defense tool and/or holster. The same reference number may be used to indicate elements, mechanisms, assemblies, or features that are not identical in form, shape, structure, etc., yet which provide similar functions or benefits. Additional reference characters (such as letters, primes, or superscripts, as opposed to numbers) may be used to differentiate similar elements or features from one another. It should be understood that for ease of description the disclosure does not always refer to or list all the components of the self-defense tool, and/or holster, and that a singular reference to an element, member, or structure, e.g., a singular reference to an indentation, may be a reference to one or more such elements, unless the context indicates otherwise.
In the following description of various embodiments of the self-defense tool, and/or holster, it will be appreciated that all directional references (e.g., proximal, distal, upper, lower, upward, downward, left, right, lateral, longitudinal, front, rear, back, top, bottom, above, below, vertical, horizontal, radial, axial, interior, exterior, clockwise, and counterclockwise) are only used for identification purposes to aid the reader's understanding of the present disclosure unless indicated otherwise in the claims, and do not create limitations, particularly as to the position, orientation, or use in this disclosure. Features described with respect to one embodiment typically may be applied to another embodiment, whether or not explicitly indicated.
Connection references (e.g., attached, coupled, connected, and joined) are to be construed broadly and may include intermediate members between a collection of elements and relative movement between elements unless otherwise indicated. As such, connection references do not necessarily infer that two elements are directly connected and in fixed relation to each other. Identification references (e.g., primary, secondary, first, second, third, fourth, etc.) are not intended to connote importance or priority, but are used to distinguish one feature from another. The drawings are for purposes of illustration only and the dimensions, positions, order and relative sizes reflected in the drawings attached hereto may vary.
Embodiments of the present invention are not limited to the particular methodology, uses, and applications described herein, as these may vary. It is also to be understood that the terminology used herein is used for the purpose of describing particular embodiments only, and is not intended to limit the scope of the embodiments of the invention. It must be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include the plural reference unless the context clearly dictates otherwise. Thus, for example, a reference to “an element” is a reference to one or more elements, and includes equivalents thereof known to those skilled in the art. Similarly, for another example, a reference to “a step” or “a means” is a reference to one or more steps or means and may include sub-steps or subservient means. All conjunctions used are to be understood in the most inclusive sense possible. Thus, the word “or” should be understood as having the definition of a logical “or” rather than that of a logical “exclusive or” unless the context clearly necessitates otherwise. Structures described herein are to be understood also to refer to functional equivalents of such structures. Language that may be construed to express approximation should be so understood unless the context clearly dictates otherwise.
Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.
Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which this invention belongs. Preferred methods, techniques, devices and materials are described although any methods, techniques, devices, or materials similar or equivalent to those described may be used in the practice or testing of the present invention.
All patents and other publications discussed are incorporated herein by reference for the purpose of describing and disclosing, for example, the methodologies described in such publications that might be useful in connection with the present invention. These publications are provided solely for their disclosure prior to the filing date of the present application. Nothing in this regard should be construed as an admission that the inventors are not entitled to antedate or otherwise remove any such publication or patent as prior art for any reason.
With reference to
The curved blunt inner portion 3 may include a number of indents or notches 8. Indents 8 may be rounded, smooth and be sized for use or to be held by a user as finger grips. While four indents 8 have been shown it will be appreciated that more or less indents 8 may be used. It is further contemplated that the indents 8 on the inner blade portion 3 may be rubberized or us other constructions and materials to increase the ability to grip the blade portion 1 by the user. The blade portion 1 preferably is formed of steel although other materials of construction are contemplated. The blade portion preferably has a thickness 27 (shown in
The grip or handle portion 6 preferably is designed to be ambidextrous. The grip portion 6 preferably is substantially straight and has a longitudinal axis 13. The grip portion 6 may range in length 18 from as little as about 10 cm to as much as about 18 cm, more preferably about 12 cm to about 16 cm. In one embodiment, grip portion 6 has a length 18 of about 15 cm. Other shapes and sizes for the grip portion 6 are contemplated. Grip portion 6 may be formed of steel although other materials of construction are contemplated, including having rubberized portions or covering to increase grip, or other constructions to facilitate gripping and using the tool 10.
Grip portion 6 includes an end 5 that preferably is pointed and includes a number of edges 7. The end 5 may be, for example, pyramidal in shape and come to a sharp point 16. The end 5 may have any number of edges 7 and a corresponding number of sides 22. The edges 7 may be sharp and designed to cut into body tissue of an attacker. In one embodiment, as shown in
The handle or grip portion 6 may include grip indents 11 to facilitate gripping the handle so the tool 10 does not slip off the user's hand. In the event the user's hand slides off the grip portion 6, the pointed end 5 may have a lip portion to catch the tool, and/or a bevel to protect the user's hands from injury.
The tool 10 may be deployed in a number of ways. For example, it can be held by the blunt portion 2 to mimic a handgun in an attempt to cause the attacker to pause. It can be used as a blocker to block attacks by someone wielding a knife or some other hand weapon. The edges 7 may be sharp to provide additional defensive protection.
The tool 10 may be a single molded piece or may include two detachable/re-attachable sections, for example, the blade portion 1 and grip portion 6, and may be used as two separate weapons. The sections may comprise interchangeable parts, for example, the blade portion 1 may be replaceable, may have parts that are rubberized and/or dulled replacement metal alloy for training purposes, and the like. The pointed end 5 of the grip 6 may also be replaceable.
The tool 10 is designed for natural body movement if the user is surprised and is designed to minimize injury to user. For example, if the user is attacked by a third party when walking down the street, the general instinct is to pull back and put hands up. When holding the tool, the user will be protected from a number of attack angles.
The tool 10 also has military applications. Law enforcement, fire fighters and combatants who work in an urban environment or deployment in a war zone (close quarters and room clearing) are susceptible to losing their handgun and often get killed and/or injured by their own weapon. Tool 10 is an option for additional protection. It can be handled in a holster or in the open and it does not fall under most, if not all, legal guidelines of an edged weapon due to the small size of the sharpened blade portion 9. A different type of steel may be used for commercial applications, with military applications being made of a harder steel. The weight may be controlled by boring out some of the handle. When a soldier has been walking for miles, in a firefight, this is designed to be held easily, as a backup to protect the user.
In one embodiment, the grip and blade portion may be separable pieces and replacement training parts can be a part of the design. In another embodiment, the tool may be constructed out of one single piece of material. The disclosure is not limited in this regard.
Referring now to
The blade portion 1 as shown in
With reference to
Proportions shown in any figures accompanying this disclosure are for illustration purposes only and may also be adjusted without departing from the spirit of the invention.
The tool 10 can be used to defensively protect against attack. Should a would-be attacker move toward the user, holding the tool 10 with the pointed end 5 out allows the user to jab the attacker with the pointed end 5. The attacker would likely recoil instinctively and allow the user to run away or position for further defense. For example, the tool 10 can be held with the curved blade portion 1 out to allow the user to hook the attacker. Because of the reverse cut on the blade portion 1, the attacker would only be sliced if they attempt to pull away. The distinctive wounds left by the tool 10 also enable easy identification of the attacker for prosecution.
The claims, as originally presented and as they may be amended, encompass variations, alternatives, modifications, improvements, equivalents, and substantial equivalents of the embodiments and teachings disclosed herein, including those that are presently unforeseen or unappreciated, and that, for example, may arise from applicants/patentees and others.
The foregoing description has broad application. It should be appreciated that the concepts disclosed herein may apply to many types of self-defense tools and/or holsters, in addition to those described and depicted herein. For example, the concepts may apply equally to another holster, or blade portion or handle assembly. The discussion of any embodiment is meant only to be explanatory and is not intended to suggest that the scope of the disclosure, including the claims, is limited to these embodiments.
Those skilled in the art will recognize that the self-defense-tool and/or holster has many applications, may be implemented in various manners and, as such is not to be limited by the foregoing embodiments and examples. Any number of the features of the different embodiments described herein may be combined into a single embodiment. The locations and sizes of particular elements, for example, the indentations, the sharpened portion, the blunt portions etc., may be altered. Alternate embodiments are possible that have features in addition to those described herein or may have less than all the features described. Functionality may also be, in whole or in part, distributed among multiple components, in manners now known or to become known.
It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the invention. While fundamental features have been shown and described in exemplary embodiments, it will be understood that omissions, substitutions, and changes in the form and details of the disclosed embodiments of the self-defense tool and/or holster may be made by those skilled in the art without departing from the spirit of the invention. Moreover, the scope of the invention covers conventionally known, and future-developed variations and modifications to the components described herein as would be understood by those skilled in the art.
In the claims, the term “comprises/comprising” does not exclude the presence of other elements, features, or steps. Furthermore, although individually listed, a plurality of means, elements, or method steps may be implemented by, e.g., a single unit, element, or piece. Additionally, although individual features may be included in different claims, these may advantageously be combined, and their inclusion individually in different claims does not imply that a combination of features is not feasible and/or advantageous. In addition, singular references do not exclude a plurality. The terms “a”, “an”, “first”, “second”, etc., do not exclude a plurality. Reference signs or characters in the disclosure and/or claims are provided merely as a clarifying example and shall not be construed as limiting the scope of the claims in any way.
Accordingly, while illustrative embodiments of the disclosure have been described in detail herein, it is to be understood that the inventive concepts may be otherwise variously embodied and employed, and that the appended claims are intended to be construed to include such variations, except as limited by the prior art.
This application claims priority to U.S. Provisional Application Ser. No. 62/341,968 filed May 26, 2016, which is incorporated herein by reference as if fully disclosed herein.
