DETAILED DESCRIPTION

As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.

Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.

Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.

Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.

Regarding applicability of 35 U.S.C. §112, ¶6, no claim element is intended to be read in accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to apply in the interpretation of such claim element.

Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”

When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers,” “a picnic basket having crackers without cheese,” and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”

Referring now to the drawings, in which like numerals represent like components throughout the several views, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses.

For personal self-protection, the user attaches the invention onto their wrist using the wrist band 14. It is orientated with spray nozzle on the bottom side of user's wrist and the vessel tab 16 and cartridge tab 18 at the top side of the wrist.

When the user squeezes the vessel tab 16 and the cartridge tab 18 together the contents vessel 10 slides within slide cartridge 12 causing the spray nozzle 20 to press against the nozzle stop 22, releasing the pepper spray or similar contents that is contained in the contents vessel 10.

In at least some embodiments, but not necessarily all, instead of a mechanical means, an electronic ignition can be used to start the self-defense spray.

In at least some embodiments, but not necessarily all, other shapes are used for the vessel for the chemical and propellant. These could include a round, tube-like design that might use multiple, side-by-side tubes connected.

In at least some embodiments, but not necessarily all, a valve is used that punctures the vessel, releasing its contents.

In at least some embodiments, but not necessarily all, instead of being worn on the wrist, the invention can be worn in places including, but not limited to around the neck, attached to top, on belt, on hat or as part of other products like water bottles, and purse.

In at least some embodiments, but not necessarily all, the vessel can be designed to be refillable or prefilled vessels can be purchased to replace spent one.

In at least some embodiments, but not necessarily all, electronics can be integrated into the invention, providing common features currently found on existing wearables.

In at least some embodiments, but not necessarily all, a feature that contacts the 911 emergency network, sending GPS coordinates when self-defense feature is activated.

FIG. 9 is a perspective, partially schematic view of a wearable spray canister with trigger and safety mechanism in accordance with one or more preferred embodiments of the present invention, and FIG. 10 is an exploded view of the wearable spray canister with trigger and safety mechanism of FIG. 9.

Positioned on the exterior, a top vessel 110, is the valve housing 112, which together form a single interior cavity. Inserted into the valve mechanism contained in the valve housing 112 is an actuator 116 that when pressed allows the release of the contents trough the spray insert 118. This is shown in some detail in FIGS. 9 and 10.

In FIG. 9 a cover 114 is shown connected to the vessel 110 via a cover connection groove 120. Positioned on the plane surface is the spray opening 124. The spray opening 124 is located at the spot on the cover 114 directly a top the position of the spray insert 118 when the actuator 116 is triggered. Adjacent to the cover connection groove 120 is a housing connection groove 122, which may be a means to add a peripheral like a clip, wrist band, necklace, adhesive or other housing for functional and/or aesthetic purposes. Also, shown on cover 114 is a safety tab opening 126 and a trigger tab opening 128 which, when cover 114 is seated, allows a trigger tab 130 and a safety tab 132 to partially protrude beyond the circumference defined by the vessel 110. This embodiment describes an indentation around the exterior of vessel 110, but other attachment methods are possible.

Attached to actuator 116 is the trigger tab 130 which slides parallel to the top plane of the vessel 110 toward the valve housing 112. Similarly the safety tab 132, also moves along the top plane of vessel 110 towards the opposite side of the valve housing. Positioned on the safety tab 132 are indentations identified as obstruction relief 138. Positioned adjacent and independent moving is a safety obstruction 136. Spring 134 are secured in the longitudinal centers providing resistance at one end against the trigger tab 130 and at the other end the safety tab 132. FIG. 11 shows the assembly in its stand-by mode at the ready with the springs 134 relaxed.

FIG. 12 illustrates the assembly in its active mode with the springs 134 compressed and the safety obstruction 136 seated in the obstruction relief 138 allowing the actuator 116 to be pressed towards the valve housing 112.

To activate this invention for personal protection, the user squeezes the trigger tab 130 and safety tab 132 towards each other. The spring 134 keeps the tabs in stand-by mode until activated by the user.

To prevent accidental activation, the trigger tab 130 is blocked from movement by the safety obstruction 136. Movement is preferably only permitted when the trigger tab 130 and the safety tab 132 are pressed simultaneously. When this happens the safety tab 132 moves the obstruction relief 138 cutout directly adjacent to the safety obstruction 136. The movement of the trigger tab 130 towards the valve housing 112 forces the actuator 116 to pushes away the safety obstruction 136 into the obstruction relief 138 allowing the actuator 116 to open the value in the valve housing 112, releasing the contents, which is under pressure, from the interior of the vessel 110 through the spray insert 118. Based on the content's properties, the spray insert 118 is designed to maximize the shape and characteristics of the spray.

Contents may include, but are not limited to, one or more chemical irritants such as pepper spray, mace, tear gas, chloroacetophenone, CNB, CR, red gel, and criminal identifying gel.

In at least some embodiments, but not necessarily all, instead of a mechanical means, an electronic ignition can be used to start the self-defense spray.

In at least some embodiments, but not necessarily all, a trigger mechanism is included that operates by the pulling of a cord-like component using fingers or teeth.

In at least some embodiments, but not necessarily all, other shapes are used for the vessel for the chemical and propellant. These could include a round, tube-like design that might use multiple, side-by-side tubes connected.

In at least some embodiments, but not necessarily all, a valve is used that punctures the vessel, releasing its contents.

In at least some embodiments, but not necessarily all, the vessel is designed so it can be refillable.

In at least some embodiments, but not necessarily all, electronics are integrated into the invention, providing common features currently found on existing wearable sensor products.

In at least some embodiments, but not necessarily all, a feature is added that contacts to the 911 emergency network, sending GPS coordinates when self-defense feature is activated.

In at least some embodiments, but not necessarily all, a loud, audible alarm feature is added that can be activated in conjunction with the invention's primary use or as a separate feature.

In at least some embodiments, but not necessarily all, a feature is included that allows the invention to be electronically tethered to a smart phone.

In at least some embodiments, but not necessarily all, an advantage is the non-cylindrical shape, diminutive size allows it to be discreetly worn by the user.

In at least some embodiments, but not necessarily all, an advantage is how the invention's trigger mechanism enables easy, controlled use, but with a safety feature that prevents accidental discharge.

In at least some embodiments, but not necessarily all, an advantage is that the invention can be used in conjunction with a variety of housings, including, but not limited to wrist band, bracelet, necklace, finger ring, adhesive-backed and clip.

In at least some embodiments, but not necessarily all, an advantage is the cover can be in different colors, shapes, designs, and materials.

In at least some embodiments, but not necessarily all, an advantage is that the releasing valve is of a commonly used design. This prevents time-consuming and expensive testing that would be typical with a new, unproven design.

In at least some embodiments, but not necessarily all, an advantage is that the vessel, trigger mechanism, cover and housings are separate and interchangeable.
