Abstract
A target for darts includes foil sheets 2, 4 separated by a cork layer 3. A dart point penetrating sheets 2, 4 completes a circuit to energize bulbs 9. <IMAGE>
Description
SPECIFICATION
Dart switch circuit
The invention I wish to describe below is made up of materials readily available from retail outlets. The invention consists of a sequence of assembly with an electrical wire attached which is to be known as a DART
SWITCH CIRCUIT. (as described in drawing reference one)
A piece of cork cut from a roll to the dimensions required for the target required for game, fete board, advertising gimmick ect asecond piece is cut the same shape as the first but slightly smaller (drawing two) a piece of alluminum cooking foil folded in two cut to the same size as cork as cut in drawing one, at this stage an insulated piece of wire is bared pushed through the foil and splayed out.
Another piece of foil is taken and worked as the first piece but cut to the size as drawing two, a piece of chipboard or ply is cut larger than the piece of cork as per drawing one, two holes are drilled diagonal in the board to accomodate the leads.
All the parts are ready for assembly as shown in close detail in drawing three. A perfectly safe low voltage current supplied from a dry cell torch type battery, 1 2 volt car battery or a 1 2 volt 5 amp transformer is placed in circuit with a bulb, motor, tape recorder as per drawing four.
Operation is activated by throwing a standard dart at the pad.The point of the dart penetrates the insulation of the already energised pad causing the mettalic point of the dart to convey electricity from one plate to the next forming a switch. To turn off the circuit the dart is withdrawn or by having a timer inserted into the circuit.(switch pads when beyond serviceable life can be exchanged with a replacement unit)
It is essential that there is no contact between the plates after assembly, the circuit will not short out only the accessory in circuit but will speadily consume the battery. This patent will also include any drawing specification mentioned on patent 8039348 dated 9.12.80
CLAIMS
Target device for automatically indicating the presence of the hit point of a dart, the point of the dart penetrates the two electrically insulated parallel sheets mounted closely one behind the other, the velocity of the projected missile wedges its self into the wood at the same time bridging the two plates thereby continuing the circuit and functioning the equipment in circuit.
