Patent ID: 8616934

Claim:
An alternative dart tip device ( 100 ) consisting of: (a) a first impact plate ( 110 ) and a second impact plate ( 120 ), the impact plates ( 110 , 120 ) being positioned parallel to each other, wherein a bottom surface of the second impact plate ( 120 ) is attached to a tip end of a dart ( 101 ), the dart ( 101 ) being a cylindrical body with a uniform diameter ( 170 ) along a whole length ( 190 ) of the body, wherein the body is free of any projection from an exterior surface; (b) a connecting means for connecting the first impact plate ( 110 ) to the second impact plate ( 120 ), the connecting means allows the first impact plate ( 110 ) and the second impact plate ( 120 ) to be moved between a contact position where the first impact plate ( 110 ) and second impact plate ( 120 ) are moved towards each other to be nearly contacting each other and a non-contact position where the first impact plate ( 110 ) and second impact plate ( 120 ) are moved away from each other to be apart a certain distance, the certain distance being between about 4/64 to 5/64 inches; wherein the connecting means consists of (i) a first aperture ( 145 a ) and a second aperture ( 145 b ) disposed on a first rim of the first impact plate ( 110 ); (ii) a third aperture ( 145 c ) and a fourth aperture ( 145 d ) disposed on a second rim of the second impact plate ( 120 ), the third aperture ( 145 c ) being aligned with the first aperture ( 145 a ) on the first impact plate ( 110 ) and the fourth aperture ( 145 d ) being aligned with the second aperture ( 145 b ) on the first impact plate ( 110 ); (iii) a first wire ( 140 a ) looping through the first aperture ( 145 a ) of the first impact plate ( 110 ) and the third aperture ( 145 c ) of the second impact plate ( 120 ) to tie the first impact plate ( 110 ) and second impact plate ( 120 ) together; (iv) a second wire ( 140 b ) looping through the second aperture ( 145 b ) of the first impact plate ( 110 ) and fourth aperture ( 145 d ) of the second impact plate ( 120 ) to tie the first impact plate ( 110 ) and the second impact plate ( 120 ) together; (c) a cap ( 160 ) disposed on a top surface of the second impact plate ( 120 ); and (d) a shaft ( 180 ) having a first end attached to a bottom surface of the first impact plate ( 110 ) and a second end extending downwardly toward the cap ( 160 ), the shaft ( 180 ) functions to penetrate the cap ( 160 ) when the impact plates ( 110 , 120 ) move to the contact position; wherein when the dart tip device ( 100 ) is thrown and the first impact plate ( 110 ) impacts an object, the impact plates ( 110 , 120 ) move to the contact position, and the shaft penetrates the cap ( 160 ) which causes the cap ( 160 ) to explode.
