The present disclosure generally pertains to key holders, and is more particularly directed towards a key holder that facilitates a user to use a key as a weapon.
Personal defense comes in many forms and may be needed in many places. One may find himself in a dangerous situation where there is no one around and must improvise using items that are readily at hand. Frequently, persons carry a set keys on their person when out of the home. Keys are typically made of metal and can make for an improvised weapon when needed. In addition, keys can be a self-defense aid that can be carried where others cannot (e.g., were designation weapons are banned). However, when one fears that their personal safety is at risk, and holds a key between their own fingers as a makeshift self-defense aid, one is often at risk of cutting their own hand in the event they do encounter an attacker and are forced to use the key between their fingers in this way to defend themselves.
U.S Pat. App. Pub. No. 20120088587 to Zaccari, et al. and published on Apr. 12, 2012, shows a security device and security system. The disclosed security device and system includes a substantially flat body with an opening formed therein. The opening has a predetermined length and a predetermined height such that an elongated end of a key passes through the opening and a head end of the key does not pass through the opening. A user gripping the security device may then use the elongated end of the key extending outward therefrom as a weapon or tool for self-defense. In the heat of the moment, it may be difficult to fiddle this system and may require the user to focus on its assembly rather than the urgency at hand.
The present disclosure is directed toward overcoming known problems and problems discovered by the inventor. Further, the present disclosure addresses these problem while providing a discrete form of self-defense.
Aspects of the present disclosure generally pertain to an apparatus and method for holding a key for self-defense. Aspects of the present disclosure more specifically are directed toward a self-defense key holder or an apparatus that rapidly converts a key (e.g., house key) into a fighting weapon, for example, for self-defense. The defense key holder may utilize an existing key (e.g., home/office/auto) to replace bulky and often prohibited self-defense aids. This disclosure may be useful for giving a user additional control and force in a variety of motions with a key or other object.
An apparatus for holding a key while striking a person with the key is disclosed herein, where the key is characterized by a finger gripping plane and an axis of rotation within said finger gripping plane, a front tip, and a back opposite the front tip relative to the axis of rotation. The apparatus for holding a key includes a key mount, a user grip, and a pivot couple. The key mount is configured to rigidly mount to and envelope at least a portion of the key while leaving the front tip of the key exposed, the key mount is further configured to remain rigidly mounted to the key while striking the person with the tip of the key. The user grip includes a first finger grip and a second finger grip, with the first finger grip is configured to be gripped by and between at least a first finger and a palm of a hand of a user while striking the person with the tip of the key, and the second finger grip is configured to be gripped by and between at least a second finger and the palm of the hand of the user while striking the person with the tip of the key. The pivot couple is fixed to the key mount and is fixed to the user grip between the first finger grip and the second finger grip. The pivot couple is configured to position the key mount forward of the user grip. The pivot couple is further configured to rotatably couple the key mount to the user grip, where the key mount and the user grip can rotate between a stowed state and a deployed state. Here, the stowed state is where the user grip is substantially parallel to the finger gripping plane and the key mount, and the deployed state is where the user grip is substantially perpendicular to the finger gripping plane and the key mount.
According to one embodiment, an apparatus for gripping a key while striking a person with the key is disclosed herein, where the key is substantially planar and has an operational axis of rotation, a front tip, and a back, the back being opposite the tip relative to the axis of rotation. The apparatus for gripping a key includes a key mount, a user grip, and a pivot couple fixed to the key mount and to the user grip. The key mount is configured to fixedly attach to the key while leaving the front tip of the key exposed, and to remain fixedly attached to the key while striking a person with the tip of the key. The user grip includes a first finger grip, a second finger grip, and a thrust butt rigidly fixed together. The user grip is configured to be gripped by the first finger grip, the second finger grip, and the thrust butt between at least two fingers and a palm of a user while striking the person with the tip of the key. The pivot couple is fixed to the user grip between the first finger grip and the second finger grip. Further, the pivot couple is configured to rotatably couple the key mount to the user grip such that the key mount and the user grip are conversely rotatable about a single axis between a stowed state and a deployed state. Here, the stowed state is where the key mount and the user grip are substantially parallel to each other, and the deployed state being where the key mount and the user grip are substantially perpendicular to each other.
According to another embodiment, an apparatus for holding a key while striking a person with the key is disclosed herein, where the key is key characterized by a finger gripping plane and an axis of rotation within the finger gripping plane, a front tip, and a back opposite the front tip relative to the axis of rotation. The self-defense key holder includes a key mount configured to rigidly mount to and envelope at least a portion of the key while leaving the front tip of the key exposed, a user grip including a first finger grip, a second finger grip, and a thrust butt rigidly fixed together, and a pivot couple fixed to the key mount and to the user grip. The key mount is further configured to remain rigidly mounted to the key while striking the person with the tip of the key. The user grip is configured to be gripped by the first finger grip, the second finger grip, and the thrust butt between at least two fingers and a palm of a user while striking the person with the tip of the key. The pivot couple is fixed to the user grip between the first finger grip and the second finger grip, and is configured to position the key mount forward of the user grip. The pivot couple is further configured to rotatably couple the key mount to the user grip such that the key mount and the user grip are conversely rotatable about a single axis between a stowed state and a deployed state. Here, the stowed state is where the key mount and the user grip are substantially parallel to each other, and the deployed state is where the key mount and the user grip are substantially perpendicular to each other.
Aspects of the present disclosure generally pertain to a self-defense key holder. Generally, the self-defense key holder is a device or apparatus that rapidly converts a key (e.g., house key) into a fighting weapon, for example, for self-defense. The defense key holder utilizes an existing key (e.g., home/office/auto) as an option to bulky and often prohibited self-defense aids.
The key mount 110 is configured to fixedly attach to the key 10 and withstand thrusts at a person, for example, using the tip 11 of the key 10. In other words, the key 10 will remain secured to the key mount 110 despite stabbing or otherwise striking an attacker the tip 11 via the apparatus 100. The key mount 110 may conveniently define a finger split axis 119 that is within the finger gripping plane 98 and normal to the axis of rotation 99 of the key 10 when the key mount 110 is fixedly attached to the key 10.
The user grip 120 may include a thrust butt 122, a first finger grip 123, and a second finger grip 124. The user grip 120 may conveniently define a knuckle axis 129 extending between the first finger grip 123 and the second finger grip 124. Further, the knuckle axis 129 may be normal to the axis of rotation 99 of the key 10 when the key mount 110 is fixedly attached to the key 10. For convenience of illustration, the finger split axis 119 and the knuckle axis 129 are shown here slightly separated, however it should be understood that their exact position along the axis of rotation 99 is not material.
The pivot couple 130 may be fixed to the key mount 110, and further fixed to the user grip 120. In particular, the pivot couple 130 may be fixed to the user grip 120 between the first finger grip 123 and the second finger grip 124. The pivot couple 130 is configured to rotatably couple the key mount 110 and the user grip 120 between a stowed state and a deployed state of the apparatus 100. The stowed state may be defined by the finger split axis 119 being oriented parallel with the knuckle axis 129, as shown. The deployed state may be defined by the key mount 110 and the user grip 120 being then rotated between 45 degrees and 135 degrees, but preferably a quarter turn about the axis of rotation 99 of the key 10.
As discussed above, the key mount 110 is configured to fixedly attach to the key 10 and withstand thrusts as a weapon. According to one embodiment, portions of or all of the key mount 110 and the user grip 120 may be made of metal, hardened plastic, or materials of sufficient strength to support a desired strike force. As shown, portions of the key mount 110 and the user grip 120 may include bearing surfaces in contact with each other or otherwise configured to transfer impact loads directly between the key mount 110 and the user grip 120 (e.g., axial compression along the axis of rotation 99 of the key 10 between the tip 11 of the key 10 the thrust butt 122 of user grip 120). Beneficially, this may distribute or otherwise share loading transferred between the key mount 110 and the user grip 120 via the pivot couple 130 alone.
In use, a user may acquire a firm grip of the apparatus 100 by placing the thrust butt 122 against the palm of the hand and at least one finger on each of the first finger grip 123 and the second finger grip 124. Further, the apparatus 100 may be held with key mount 110 positioned between two of the user's fingers (e.g., index and middle fingers, middle and ring finger, etc.).
As shown, the user grip 120 may include ergonomic features configured for improved gripping. For example, the thrust butt 122 may include a convex profile or otherwise be shaped to conform to the user's hand, at the back end of the user grip 120. Also for example the first finger grip 123 and the second finger grip 124 may each include concave profiles or otherwise be shaped to conform to the user's fingers, at the tip end of the user grip 120. Further, while the illustrated embodiment only includes two finger depressions, additional depressions are contemplated, in particular for the user's thumb.
According to one embodiment, one or both of the key mount 110 and the user grip 120 may have a tapered thickness. In particular, the key mount 110 and the user grip 120 may have a maximum thickness proximate the axis of rotation 99 (
As shown, the key mount 110 may taper forward in plan view of the finger gripping plane 98. In particular, at least a portion of the key mount 110 may have a narrower width (i.e., measured in plane in the finger gripping plane 98 and perpendicular to the axis of rotation 99) proximate its tip end than towards its back end. The taper may extend the entire length (i.e., measured along the axis of rotation 99) or just a portion thereof. For example, here the taper extends from the tip end of the key mount 110 backwards to approximately the back 19 (
According to one embodiment, the apparatus 100 may include an attachment junction 160. The attachment junction 160 is an attachment point and attachment means to couple the apparatus 100 to another item, for example a key chain. The attachment junction 160 may be permanently or removably fixed to the apparatus 100. For example the attachment junction 160 may include a closed loop integrated with a portion of the key mount 110, the user grip 120, and/or the pivot couple 130. Also for example, the attachment junction 160 may alternately include a removable (e.g., screw or clip in) eyelet that is coupleable to at least one of the key mount 110, the user grip 120, and the pivot couple 130.
According to one preferred embodiment, the attachment junction 160 may be fixed to the key mount 110 or otherwise adapted to isolate loads from other components of the apparatus 100, such as the pivot couple 130. Advantageously, this may provide for hanging a weighted key ring (e.g., holding many keys) from the apparatus 100 while the key is in a keyhole (e.g., a car ignition) without accelerating wear of the pivot couple 130, as it the hanging weight is isolated from the pivot couple 130.
According to one embodiment, the apparatus 100 may include a branding pad 170. The branding pad 170 may include a designated or otherwise predefined flat area configured to be printed on, to receive a label, to be etched, or to otherwise have an indicia placed on it. Preferably the branding pad 170 will be positioned on the key mount 110, and further in a centered or symmetric location (e.g., centered on the axis of rotation 99). According to one embodiment the branding pad 170 may be at least 150 square millimeters. In one preferred embodiment, the branding pad 170 may be at least 300 square millimeters. According to another embodiment, the branding pad 170 may be molded with, etched into, embossed on, or otherwise integrated into the apparatus 100. According to yet another embodiment, the branding pad 170 may be positioned on an access door of the apparatus 100. In each, the branding pad 170 may positioned on one or both of the front and back of the apparatus 100
According to one embodiment, the apparatus 100 may be arranged and configured to have a low profile. In particular, the pivot couple 130 may be at least partially imbedded in the key mount 110 and the user grip 120. Further, the key mount 110 and the user grip 120 may be shaped, sized, and dimensioned to come substantially flush with each other on all sides while in the stowed state, as shown. Further, the key mount 110 and the user grip 120 may have a maximum thickness (i.e., measured normal to the finger gripping plane 98) of 12 to 18 millimeters. Beneficially, in this configuration, the apparatus 100, having minimal sharp edges, may facilitate carrying in pockets and bags, for example.
Further, the apparatus 100 may be arranged and configured to have a discreet, subtle perimeter. In particular, and as shown the key mount 110 and the user grip 120 may have an outer perimeter (i.e., about an axis normal to the finger gripping plane 98) having a general appearance of a key bow (e.g., tapered tip toward tip end, wider toward back end, etc.). In this way, the apparatus 100 may discreetly have an outward appearance of an oversized key, rather than as a weapon. In addition, the perimeter may have substantially smooth, gentle transitions.
According to one embodiment, the key mount 110 may be molded onto, integrated with, or otherwise permanently fixed to with the key 10. As shown, the key mount 110 may be made of a hardened plastic or other durable material that has the key 10 at partially embedded. According to another embodiment, the key mount 110 may be integrated with the key 10. For example, both the key 10 and the key mount 110 may begin as a single blank including a locking interface for the pivot couple 130, which can be subsequently keyed for a particular lock.
According to one embodiment, the key mount 110 may include a fingertip grip 113. For example and as shown, the fingertip grip 113 may be embodied as a depression or indentation in the front or back of the key mount 110.
According to one embodiment, the key mount 110 and the user grip 120 may be configured to mate or otherwise seat within each other when in the stowed state. Features on one face (i.e., front or back) may not extend to the opposite face. For example and as shown, the first finger grip 123 (not shown) and the second finger grip 124 of the user grip 120 may only have a portion or fraction of the thickness of the rest of the user grip 120 (e.g., measured at the thrust butt 122 of the user grip 120) and the key mount 110 may have mating landing pads 114. In this way the landing pads 114 of the key mount 110 may serve to prevent the user grip 120 from freely spinning (e.g., about the axis of rotation 99) in a first direction. Advantageously, the apparatus 100 may have fewer interstices or gaps when positioned in the stowed state.
According to one embodiment the key mount 110 may include one or more reverse landing pads or deployment stops 115 configured to prevent the user grip 120 from freely spinning in an opposite direction of the stow direction. In particular, the key mount 110 may include one or more deployment stops 115 configured to prevent the user grip 120 from rotating more than ninety degrees. Here, the “opposite” or “deployment” direction is generally defined as a clockwise direction about the axis of rotation 99 of the key 10, for convenience. It should be understood that the directions of deployment and stowage may be reversed in other embodiments without departing from the spirit of the disclosure.
As illustrated, the deployment stop 115 may be embodied or otherwise include a portion of a face (i.e., front or back) of the key mount 110. Alternately, the deployment stop 115 may be embodied or otherwise include an interior portion of the key mount 110 a face (i.e., a non-face, non-edge portion), such as a lip or ledge generally set perpendicular to one face or the finger gripping plane 98 (
According to one embodiment, the key mount 110 may further include a key cavity 117 sized and dimensioned to receive the key 10 and an access door 116 configured to enclose and provide access to the key 10 when in the key cavity 117. According to another embodiment, the key cavity 117 may be sized and dimensioned to receive many different shapes and sizes of the key 10. Preferably, the key cavity 117 will be sized and dimensioned for the largest of an assortment of keys 10, for example, sizes may include common home, office, and car key sizes.
According to one embodiment, the key mount 110 may further include a key bow mount 112 configured to couple the key 10 to the key mount 110. As shown, the key bow mount 112 may be embodied as a pin (i.e., an extrusion of any shape configured to restrict axial movement of the key 10) extending from one inner side of the key mount 110 toward the access door 116. Further, the bow mount 112 may be coupleable with the access door 116, as shown in
The key mount 110 may include additional or alternate mating interfaces with the key 10, such as rails, lips, recesses, and/or other positive or negative features that secure at least a portion of a circumference of the key 10 to the key mount 110 (e.g., about the bow 12 of the key 10). Advantageously, these interfaces provide for mounting solid or unperforated keys to the key mount 110. Further, these interfaces may be configured to provide lateral support, for example, against lateral movements such as a key tip slicing movement/attack.
Further, the key mount 110 may include additional or alternate mating interfaces with the key 10 such as bow pads, an undersized key cavity 117, or other features configured to hold the opposing planar surfaces of the key 10 in compression. These interfaces may be configured to secure the key 10 to the key mount 110, for example, against forces normal to the finger gripping plane 98. Advantageously, these interfaces may provide support against bending or twisting the key 10.
As shown in this embodiment, generally, the key mount 110 connects to a spring operated pin, which is connected to the user grip 120. The pin is secured in place by a notch that is released by a button. When the button is pushed the pin is released therefore rotating the user grip 120 at a 90 degree angle, locking it in place until button is pushed in and disengages the lock.
More particularly, the deployment mechanism 140 may include a trigger such as catch 142 and catch spring 144, and an energizer such as torsion spring 146. The deployment mechanism 140 may be embedded or otherwise affixed to at least one of the key mount 110, the user grip 120, and the pivot couple 130. For example, the catch 142 may be slidably coupled to the user grip 120 and retractable therein when placed under release pressure sufficient to resist the catch spring 144, thus activating/releasing the torsion spring 146 of the deployment mechanism 140 (e.g., here, opposite the tip direction). It should be understood that many other triggers and energizers are contemplated, including but not limited to electronic means. Further, the deployment mechanism 140 may include features to rapidly and/or easily deploy the apparatus 100 to its deployed state. Similarly, the deployment mechanism 140 may include features to inhibit and/or make it harder to inadvertently stow the apparatus 100 to its stowed state.
As above, the pivot couple 130 may be fixed to the key mount 110 and the user grip 120 between the first finger grip 123 and the second finger grip 124. Likewise, the pivot couple 130 may be configured to rotatably couple the key mount 110 and the user grip 120 between a stowed state and a deployed state of the apparatus 100. According to one embodiment, the pivot couple 130 may be embedded (fully or partially) in at least of one of the key mount 110 and the user grip 120, and alternately may be external (fully or partially) to at least of one of the key mount 110 and the user grip 120 or otherwise accessible to a user.
According to one embodiment, the pivot couple 130 may be configured as a spring-loaded pin. In particular, the pivot couple 130 may include a shaft 132, a head 134 fixed to one end of the shaft 132, and a retainer 136 affixable to the other end of the shaft 132. In this way, the pivot couple 130 may be conveniently and efficiently inserted into one of the key mount 110 and the user grip 120 (here, the user grip 120), into the other, and secured via the retainer 136 (here a retention ring). Further, the shaft 132 may be coaxial with the torsion spring 146 such that both share a common void or cavity, and where the torsion spring 146 is landed against both the key mount 110 and the user grip 120 the shaft 132 may be configured to support the torsion spring 146. In this embodiment, the torsion spring 146 may be arranged as either a deployment energizer, a stowage energizer, or both (e.g., selectably). According to one embodiment, the shaft 132 and the head 134 may be formed of a single material, such as steel, hard/strong polymer, composite, etc.
The light assembly 150 may be configured to light a key hole, light a walkway, and/or light a face of an attacker (potentially in a blinding manner). The light assembly 150 may include a light 152 and associated electronics and energy storage (not shown) and may be adapted to couple to the key mount 110 of the apparatus 100, for example, with one or more fasteners 154. The one or more fasteners 154 may be configured to provide a persistent couple (e.g., screws, clips, etc.) or may be readily separable (e.g., magnets, detents, etc.). For example, the one or more fasteners 154 may provide for the light assembly 150 to be separable from the apparatus 100 and independently usable.
According to one embodiment, the light assembly 150 may include a user interface configured to manually operate the light 152. For example, user interface may be integrated with the fingertip grip 113 (
According to another embodiment, the light 152 may be automatically operated, for example, by deploying the apparatus 100 from its stowed state to its deployed state, or by decoupling the light assembly 150 the light assembly 150 from its base (e.g., from the key mount 110).
Benefits of the present disclosure may include providing an ergonomic grip that protects users hand from potential injury over typical method of holding a key. Generally, a protective case that securely fits over a commonly used key, and utilizes a spring operated grip is provided, which when released, provides a user with a safe method to hold a key by the use of a comfortable grip therefore preventing them cutting their own hand. Further, the disclosure provides a compact design to easily carry with other keys. In addition, a user may advantageously have the practical use of flashlight for finding keyhole plus shining in attacker's eyes.
The above description of the various embodiments is provided to enable a person of ordinary skill in the art to make or use the subject matter of the disclosure. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other variations without departing from the spirit or the scope of this disclosure. Thus, it is to be understood that the disclosure is not intended to be limited to the examples and designs described herein, which merely represent a presently preferred implementation of the disclosure, but that the disclosure is to be accorded the widest scope consistent with the principles and novel features disclosed herein. It is to be further understood that the scope of the present disclosure fully encompasses other embodiments that may become obvious to those skilled in the art. For example, the principles of the present disclosure may be applied to other high cost items that are not vehicles but are powered, such as air conditioners for structures, or to more mobile items such as entertainment systems, solar power systems, and the like.
