FIELDThe present disclosure generally relates to shooting accessories and more particularly to shooting target accessories.
BACKGROUNDShooters and hunters practice shooting skills by shooting at targets. When shooting at targets over long distances, confirming whether the target has been hit can be challenging. For example, a shooter may fire a firearm at a steel target. Impact of a bullet against the target can cause the target to move (e.g., swing), and impact of the bullet against the target causes a sound, both of which enable the shooter to confirm the steel target was hit. When shooting the steel target over a long distance, the energy of the bullet at impact can be low such that the target does not move significantly upon bullet impact and such that the impact does not create a loud noise. Confirmation that the target has been hit is further complicated by sound attenuation across the distance between the shooter and the target and the difficulty in seeing the target over that distance. Impact confirmation can be enhanced by using specialized equipment to overcome the challenges, such as: (1) spotting scopes, binoculars, or other optics; (2) long range target cameras; and/or (3) visual target hit indicators.
Existing visual target hit indicators are complicated and expensive. For example, existing target hit indicators include unnecessarily complex sensors and microcontrollers required to operate the sensors. The components are expensive. Some target hit indicators include complex reflectors or prisms to direct light toward the shooter, and such components add cost and complexity.
SUMMARYIn one aspect, a target hit indicator is for use with a target to indicate hits of the target to a shooter. The target hit indicator comprises a housing and a target connector supported by the housing and configured to connect to the target. An impact detector supported by the housing is configured to detect hits of the target. A plurality of light sources are supported by the housing and operatively coupled to the impact detector to cause activation of the plurality of light sources to indicate the hits of the target. The plurality of light sources are arranged with respect to the target connector to be outboard of the target to be visible by the shooter when the target connector is connected to the target.
In another aspect, a target hit indicator is for use with a target to indicate hits of the target to a shooter. The target hit indicator comprises a housing including an impact detector housing portion and a light source housing portion. At least one light source is supported by the light source housing portion. An impact detector is supported by the impact detector housing portion. A target connector is configured to connect the housing to the target such that the impact detector housing portion is located behind the target and the light source housing portion is located outboard of the target to locate the at least one light source for view by the shooter.
In another aspect, a target hit indicator circuit comprises a rail configured to be energized by a power supply coupled thereto. A normally open impact detection switch is configured to close in response to a projectile striking a target. A first transistor is electrically connected in the rail. The first transistor is configured to be in an initial OFF state when the power supply energizes the rail. The first transistor is configured to switch to change to an ON state responsive to closing of the impact detection switch. At least one light source is configured to be energized by the power supply via the rail responsive to the ON state of the first transistor.

DETAILED DESCRIPTIONReferring to
Although the present disclosure discusses use of the target hit indicator 10 with respect to a steel target and firearms, it will be appreciated that the target hit indicator could be used in other target contexts and with other types of equipment without departing from the scope of the present disclosure.
The target hit indicator 10 has a front shown facing out of the page in
The front of the target hit indicator 10 includes a target mount 30 configured to mount the target hit indicator on a target. In the illustrated embodiment, the mount 30 includes a target connector 32 comprising loop material secured (e.g., adhered) to the front of the main body. As shown in

As shown in
With reference to
In the illustrated embodiment, the oscillator U1 comprises a 555 timer integrated circuit known to those skilled in the art configured in an astable multivibrator mode. In the astable mode, oscillator U1 generates a pulsed digital output whose output frequency can be adjusted by means of an externally connected RC tank circuit. As shown in
The transistor Q1, which supplies VOSC to power oscillator U1, is held on by the charge voltage of capacitor C1. Current flowing through a resistor R21 in parallel with capacitor C1, and the current IVOSC flowing to the rail and thus the LEDs, discharges capacitor C1. Once the charge on capacitor C1 is depleted, transistor Q1 turns OFF and the circuit 70 returns to standby mode with limited leakage current. Using the analog circuitry of circuit 70 to tether the vibration switch S1 to capacitor C1, which activates the transistor Q1 and, in turn, activates the LED lamps, provides a robust, reliable, and cost-effective solution that eliminates the need for computing chips (e.g., microcontrollers, processors, etc.).
As a result of the impact detector detecting an impact via the vibration switch S1, the target hit indicator circuit activates the one or more light sources (e.g., LED lamps D1 to D10) to visually indicate that the projectile hit the target. Other types of impact detectors (e.g., inertia switch, other types of vibration switches, etc.) can be used without departing from the scope of the present disclosure. In one example, as shown in
In view of the above, it will be appreciated that the target hit indicator 10 has the flash duration, flash rate, and duty cycle of the light sources controlled by analog timing circuits rather than a processor, thus reducing complexity and expense. The target hit indicator 10 is self-contained within the housing in a compact arrangement. Because the LEDs are arranged to be directly visible by the shooter, no reflector or prism is required to reflect light from the LEDs to be seen by the shooter. A small portion of the target hit indicator, namely the arm 20B with the LEDs D1-D10, is exposed and at risk of being shot, while the majority of the target hit indicator is protected by the target. In the event that the target hit indicator is shot, the circuit board is designed to that the LEDs are independently routed and will continue to operate despite others being shot or damaged. In the event all of the LEDs are destroyed, replacement of the target hit indicator is inexpensive.
In use, a user switches ON the target hit indicator 10 and mounts it to the back of a steel target 12 such that the arm 20B carrying the LEDs is exposed but the main body portion is shielded by the target. The housing 14 and housed printed circuit board extend outboard of an edge of the target to locate the LEDs to be seen by the shooter. The housing supports the power supply, hit detector, ON/OFF switch, and other electronic components to be shielded by the target.
It will be apparent that modifications and variations are possible without departing from the scope of the invention defined in the appended claims.
As various changes could be made in the above constructions and methods without departing from the scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
