The present disclosure relates to an illuminating assembly, projectile and projectile tail, and more particularly to an illuminating assembly, projectile and projectile tail which illuminates upon impact.
Darts are projectiles that are thrown or shot at targets either recreationally or in veterinary practice. The target can be a moving or stationary object, or the target can be an animal. In sport, darts are used primarily to test and hone a person's accuracy. In veterinary practice, darts are used to deliver drugs, e.g., via Remote Drug Delivery (RDD), scare off unwanted animals, to remove a small amount of tissue from an animal (e.g., for DNA analysis), to acquire a tissue sample for analysis (i.e., a biopsy), to implant a small solid device, such as an electric transmitter or transponder, in an animal, and for other purposes.
In particular, RDD is a popular method for delivering drugs to animals on a global scale. The following are examples of audiences whom use RDD:
Typically, administration is performed by a trained specialist who attempts to locate an animal within a safe darting distance and deliver a dosage of the desired drug via shooting a dart into the soft tissue area of the target animal.
There are many variables that determine the success of drug administration, including the anxiety of the target animal. As an example, an injured whitetail deer will have an elevated level of excitement thereby slowing the administration of a tranquilizer. In this instance, it might take a longer duration of time for the drugs to take effect, thereby allowing the deer to run a long distance and possibly into heavy coverage (e.g., thick woods, brush, etc.). Once this takes place, it can be extremely difficult to recover the tranquilized animal as there is no easy way to find it.
In many cases, the drug administered is an opiate-based drug. Recovery of a dart is crucial and, in the event the dart misses the animal, finding the dart could be difficult. This is especially crucial in urban-related delivery (i.e., removal of stray dogs, cats, etc.).
Darts are also often used to collect biopsies or small samples of tissue for analysis. For example, a small amount of dermis and hypodermis material becomes lodged in the dart tip, and a technician can then remove the dart and assay the tissue for DNA or another desired biometric.
In today's current market, there are base-level darts that have no tracking mechanism and rely on the ability to visually watch the animal until the drugs take effect and the animal can be approached. The obvious limitation of this is that one cannot see the animal when clear land is minimal and/or there is heavy cover. Additionally, in the market exists a very expensive GPS tracker that is attached to the dart but requires both a transponder and a receiver to track the animal/dart. In many applications, this is cost-prohibitive and thereby typically used for a small percentage of overall RDD scenarios.
Typically, lighted nocks for arrows leverage a pre-existing LED/Battery combination called a “bobber light”. This is a common product that has been on the market for a number of years originally designed for fishing. The novel aspect related to the lighted nocks is the design of the polycarbonate nock housing surrounding the “bobber light”. This housing and related technology is specifically designed for arrows and not necessarily applicable for RDD.
Lighted nocks for arrows are turned on at the “release” of the arrow. This design is based on the desired ability to “watch the arrow” in flight (e.g., like a tracer device). This is counterproductive to darting as the slow travel of the dart, if activated on “release” would be quickly visually identified by the target animal and avoided by moving out of the way of the traveling dart.
The art lacks a RDD device and a dart in general that is activated upon impact and can be visually tracked in a wide range of environments.
In accordance with one aspect of the present invention, there is provided an illuminating RDD dart, including: a drug delivery substrate and an illuminator tail assembly including a housing having a central bore battery compartment, an adjacent central bore light compartment with an (optionally detachable) stabilizer tail component, and attachment element which attaches the illuminator tail assembly to the drug delivery substrate, a battery having an actuator terminal and being slideably disposed within the battery compartment, and a light having a pair of electrical contacts and being disposed within the light compartment, wherein the illuminator tail illuminates upon impact of the dart with a target.

In accordance with another aspect of the present invention, there is provided an illuminator tail assembly, including a housing having a central bore battery compartment, an adjacent central bore light compartment, a tail component and attachment element capable of attachment to a projectile; a light having a pair of electrical contacts, disposed within and visible through the transparent light compartment; a battery having an actuator terminal and being slideably disposed within the battery compartment; and an actuator in communication with the light, wherein impact of the assembly with a target causes the battery to slide into an activated position, in which the actuator terminal is in electrical contact with one of the pair of electrical contacts and the battery casing is in electrical contact with the other one of the pair of electrical contacts causing the illuminator tail assembly to illuminate upon impact with a target.
These and other aspects of the present disclosure will become apparent upon a review of the following detailed description and the claims appended thereto.
The present disclosure relates to a projectile such as an illuminating dart. The present disclosure further relates to an illuminator dart tail, for use with, for example a RDD dart. One embodiment of the illuminating dart tail is designed to be retrofit to a RDD polycarbonate tube dart, although this design may be expanded to be adaptable to other projectiles.
The illuminated dart tail provides the user with significant benefits, such as visual location of the deployed dart upon impact, visual location of a darted animal in areas with heavy coverage; and the ability to dart during dawn, dusk, and even nighttime when low sunlight limits the ability to locate darts and darted animals. In one embodiment, the dart tail emits a flashing, color changing LED light that can be seen from a distance.
Typically, darting of animals close to dusk is not advisable as once dark, the animal is difficult to identify and recover. The advantage of darting near dusk is that it is typically cooler, which is important to the health of the target animal being tranquilized because the body temperature rises when the tranquilizer is administered; if the animal is darted in a hot environment the animal could be at risk of overheating. By darting close to dusk, the probability of recovery with the illuminated dart is significantly improved compared to traditional darting methodologies.
Another embodiment of an illuminating dart is an illuminating dart for collecting biopsies or small amounts of tissue for DNA or other types of analysis. The dart is designed to simply fall out of the animal and there is no barb or barb-type of fixture on the outside of the needle (smooth shaft needle). In an embodiment, the dart includes a farrel “cutter” on the outside protecting three barbs on the inside of the cylinder. Upon hitting the target animal, tissue enters the farrel and can be removed by a technician.
An embodiment of an illuminating remote drug delivery dart includes a drug delivery substrate and an optionally detachable illuminator tail assembly. The drug delivery substrate for the remote drug delivery dart, is designed for injecting a liquid medication (can be tranquilizing agent or other medication, such as antibiotic). The dart in an embodiment is composed of a cylindrical chamber with a tapered forward end provided with a pointed hollow needle. A conical valve bears against an annular seat in the chamber and leverages a triggering system and a plunger behind the chamber which can be activated with compressed air, combustion from a small powder charger or electronically. Upon impact, the trigger activates the release of the plunger forward causing the liquid medication to disburse from the needle into the animal.
An embodiment of an illuminator tail assembly includes a housing, battery, light, an actuator and tail component (optionally, stabilizer tail). The illuminator tail assembly can be attachable to the substrate of a non-illuminating dart and can be retrofitted by replacing the original tail with the illuminator tail. Alternately, a dart can be fabricated that includes the body of the dart and the illuminator tail. For example, a dart can be manufactured containing a drug delivery substrate and an illuminator tail.
The housing can be any projectile compatible shape, such as, for example, a cylinder or shaft. The housing can include a central bore battery compartment and an adjacent central bore light compartment. The housing around the light compartment can be made of a transparent, translucent, or other light transmitting material; the housing around the battery can be made of the same material as that around the tail or another material. The housing around the light compartment and the battery compartment can be one or more pieces. An embodiment includes a taper design of the tail housing. In an embodiment, the housing includes an attachment element that allows the illuminating dart tail to be securely attached to the body of the dart, and the dart could be either manufactured originally as a non-illuminating dart or newly with the illuminating tail. The attachment element can be threaded so that the tail is screwed on, include elements so that the tail and body can be pushed together, include clips or other types of hardware, or other configurations that allow a secure attachment of the tail to the dart body, such as by gluing.
The battery contains stored chemical energy that, upon activation, is converted into electricity and used as a source of power. In one embodiment, the battery has an actuator terminal and can slide within the battery compartment. The battery casing can be metal or another electrically conductive material, whereby the housing can be the negative source with a positive terminal extending from one end, or the opposite configuration. The battery can be of nominal capacity, for example: 25 mAh, nominal voltage: 3.0 v, maximal constant current: 3 mAh, and peak pulse current 15 mA. A suitable working temperature is approximately 40-85° C. and suitable storage temperature is approximately 10-30° C.
The light can be a light-emitting diode (LED), fluorescent light, halogen light, incandescent light, or anything that produces light. In one embodiment, an LED light has a pair of electrical contacts, e.g., a negative lead (electrode and a positive lead) and is disposed within a light compartment within the housing. When activated, the negative lead and positive lead of the light makes electrical contact with the positive terminal end of the battery and the negative casing of the battery to complete the circuit. The light color can be any color, combination of colors, or series of colors. In one embodiment, the light cycles between red, green, and blue and contains a small circuit to induce a fast/slow strobe effect and a color change effect.
The actuator includes means for “turning on” the light when the dart impacts the target. The activator can include electronic activation, chemical activation, or mechanical activation. In one embodiment that includes mechanical activation, as illustrated in
The illuminating tail can optionally include a stabilizer tail or a smooth tail. The stabilizer tail component can be polypropylene material and pantone 1645C in color. The purpose is to stabilize the dart in flight, reduce dart drift and wobble, and improve accuracy.
The dart can be of a reusable or disposable design and is activated (turned on upon impact. Upon impact, the force of impact drives the battery forward into the tapered end of the housing, thereby completing the circuit and activating the light. The force of impact is great enough to drive the battery tightly into the taper such that the reversal of battery movement would take a force substantially greater than normal course of activity would allow and thereby preventing loss of connection/deactivating the light. In another embodiment, there is a means of holding the battery in position upon activation, thereby preventing premature deactivation. In the case of one embodiment of an RDD dart with illuminating tail, the activation is designed to operate at or below the ranges of force that discharge the drug delivery upon impact. For example, a 40 g dart traveling an average of 100 feet per second (fps), has sufficient impact force to discharge the drug payload. The desired impact for the dart discharge is sufficient to activate the light. The activation is designed to prevent activation by the relatively smaller forces of acceleration when the dart is being handled before use and also when the dart is initially shot at the target, but the illuminating tail should be activated upon impact with the target. In an embodiment with a slide-activation mechanism, the battery would not complete the circuit/make contact with the LED light during assembly, shipping, or general handling.
The dart can be thrown by hand or shot by a blowgun, dart gun, dart projector, or the like.
In an embodiment, an original equipment manufacturer (OEM) dart can be retrofitted with the illuminator tail such that the illuminator tail illuminates upon impact with a target. Operation of the illuminator tail involves first, removal of the existing OEM tail on the dart, and replacing it with the illuminator dart tail. This can be done by pulling off the existing stabilizer tail by hand and installing the illuminator tail by pressing the attachment element on by hand. Once the illuminator dart tail is installed on the dart, the desired drug is inserted into the dart when the dart is an RDD. The dart is then loaded into the Dart Projector, for example, a cartridge fired dart gun. The target animal is then shot into the prescribed soft-tissue area and, upon impact of the dart, the battery slides forward and becomes jammed into the tapered end of the illuminator dart tail housing thereby completing the positive/negative connection and turning on the LED component.
Another embodiment of the illuminated dart tail is compatible with darts designed to inject drugs via the capture of spent gas through the barrel of the projector, e.g., dart gun, into the dart via a one-way valve. This version of the illuminated dart tail accommodates the flow and directing of spent gas (compressed air, charge gas, carbon dioxide, etc.) through small vents surrounding the lower portion of the dart tail housing. The spent gas then enters into an air chamber within the RDD dart thereby “charging” the dart while being shot through the projector/dart gun for discharge of the drug upon impact.
Operation of this embodiment of the illuminator tail involves insertion of the illuminator tail onto the RDD gas capture vent. This may be done by placing a single drop of permanent glue onto the inside of the vented end of the illuminator tail and pressing the illuminator tail on by hand. Once the illuminator dart tail is installed on the RDD, the desired drug is inserted into the RDD. The RDD is then loaded into the dart projector (e.g., a cartridge-fired dart gun).
