Hit-scoring apparatus and target panel for shooting practice

1. A hit-scoring apparatus for shooting practice, comprising:

a target holder having a body constituting a fixed first jaw and a movable second jaw of a clamping device, said first jaw and said second jaw being electrically insulated from one another, a closure mechanism for imparting to said second jaw a substantially linear movement relative to the first jaw; and

a target panel clampable between said first and second jaws, said target panel having a plurality of layers including an electrically conductive first layer and an electrically conductive second layer separated and spaced apart from said first layer by at least one electrically non-conductive layer, wherein when said target panel is clamped between the first and second jaws of said target holder, separate electrical contacts are established between predefined areas of said first and second layers and said first jaw, said electrical contacts being further connectable to a hit-scoring unit;

characterized in that:

a. the first jaw supports on a rear surface thereof a plurality of first and second electrical contacts, at least one of which first electrical contacts is adapted make contact with at least one respective area of the electrically conductive first layer and at least two of which second electrical contacts are adapted make contact with respective areas of the electrically conductive second layer through one or more respective apertures or gaps formed in the first layer;

b. each of the first electrical contacts is connectable to a source of first polarity DC voltage, each of the second electrical contacts is connectable to a source of opposite second polarity DC voltage via a respective normally open switch that is adapted to close in response to a bullet penetrating between the first layer and the second layer thereby applying said first polarity DC voltage to the respective switch coupled to the second electrical contact;

c. a respective first indicator is coupled to each of the first electrical contacts and is responsive to the switch closing for producing a first signal indicative of an area in the first layer hit by the bullet;

d. a respective second indicator is coupled to each switch and is responsive to the switch closing for producing a second signal indicative of an area in the second layer hit by the bullet; and

e. said hit-scoring unit is adapted for coupling to each of the first indicators and to each of the second indicators and is responsive to the respective first and second signals for determining an area of the target that is commonly connected to the respective first and second contacts.

2. The apparatus according to claim 1 , wherein the fixed jaw further comprises elongated lugs projecting from and fixedly attached to opposite sides of the jaw, said lugs registering with and engaging complementarily shaped, apertures in the lower part of said target panel.

3. The apparatus according to claim 2 , wherein the movable jaw includes apertures registering with and accommodating the lugs in the fixed jaw.

4. The apparatus according to claim 1 , wherein each of the jaws comprises a central section and two lateral sections inclined with respect to the central section at an obtuse angle and the target panel is provided with two longitudinally extending creases, imparting to the target panel a cross-sectional shape conforming to a gap between the fixed jaw and the movable jaw.

5. The apparatus of claim 1 , wherein the closure mechanism includes a self-locking toggle clamp mechanism.

6. The apparatus according to claim 1 , wherein the first indicator includes a timer for producing the first signal of sufficient duration to allow the hit-scoring unit to scan all of the first and second indicators in order to determine which are active.

7. The apparatus according to claim 1 , wherein the second indicator includes a timer coupled to the respective contact pad in the second layer via said normally open switch, said time being configured to produce the second signal of sufficient duration to allow the hit-scoring unit to scan all of the second indicators in order to determine which is active.

8. The apparatus according to claim 7 , wherein the normally open switch is an opto-coupler or a transistor.

9. The apparatus according to claim 1 , further including a processor operatively coupled to each first indicator and to each second indicator and being configured to access a memory storing data that maps discrete contact areas to respective contact pads in the two layers.
