Abstract
Abstract A dart for use with a target to play a game. The darts have detachable tips in the form of markers which adhere to the target on impact; the dart then separates from the marker, leaving the marker secured to the target to precisely indicate where the dart had made its hit on the target. The marker may have a strong adhesive means such as ''''Velcro'''' hooks on its front surface which will adhere to the target surface when the dart strikes the target. The surface of the target could be particularly adapted to adhere to the marker. Individual darts could also be used as play devices which would attach their markers to various cloth or fabric surfaces against which the dart was thrown.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
145 words
A dart for throwing against a target surface comprising: a body having a front end, at least two markers attached to the front end, said at least two markers being releasibly supported on said front end in overlying relation to one another, first attachment means to releasibly hold the markers to the front end, one marker being positioned most forwardly to contact the target surface first upon striking thereof by the dart, second attachment means on said markers to releasibly hold the markers to a target surface, said second attachment means providing substantially greater adhesion to said target than said first attachment means has to said front end, whereby on impact of the dart against said target surface one of said markers will adhere to the target surface and the dart will release itself from the marker, each time the dart impacts such a surface.
Claim 2
Dependent Claim
145 words
A dart for throwing against a target surface comprising: a body having a front end, at least two markers attached to the front end, said at least two markers being releasibly supported on said front end in overlying relation to one another, first attachment means to releasibly hold the markers to the front end, one marker being positioned most forwardly to contact the target surface first upon striking thereof by the dart, second attachment means on said markers to releasibly hold the markers to a target surface, said second attachment means providing substantially greater adhesion to said target than said first attachment means has to said front end, whereby on impact of the dart against said target surface one of said markers will adhere to the target surface and the dart will release itself from the marker, each time the dart impacts such a surface.
Claim 3
Dependent Claim
14 words
The dart of claim 1 wherein said second attachment means is a hooked surface.
Claim 4
Dependent Claim
20 words
The dart of claim 1 wherein said first attachment means is a frictional engagement between the markers and the body.
Claim 5
Dependent Claim
22 words
The dart of claim 3 wherein said front end includes means defining a recess for receiving the markers in a friction fit.
Claim 6
Dependent Claim
14 words
The dart of claim 3 wherein said second attachment means is a hooked surface.
Claim 7

20 words
The combination of claim 9 wherein said target means comprises a fabric sheet supported in a generally upright taut condition.
Claim 12
Dependent Claim
163 words
A dart for throwing against a target surface comprising: a body having a front end, at least two markers releasibly supported on said front end in overlying relation to one another such that one of said markers will adhere to the target surface each time the dart impacts said surface, said front end having a recess therein for receiving said markers in stacked relation, means being provided to releasibly retain said markers in said recess and means for urging said markers to the front of said recess, first attachment means to releasibly hold the markers to the front end, second attachment means on said markers to releasibly hold the marker to the target surface, said second attachment means providing substantially greater adhesion to said target surface than said first attachment means has to said front end, whereby on impact of the dart against said target surface a marker will adhere to the target surface and the dart will release itself from the marker.
Claim 13
Dependent Claim
163 words
A dart for throwing against a target surface comprising: a body having a front end, at least two markers releasibly supported on said front end in overlying relation to one another such that one of said markers will adhere to the target surface each time the dart impacts said surface, said front end having a recess therein for receiving said markers in stacked relation, means being provided to releasibly retain said markers in said recess and means for urging said markers to the front of said recess, first attachment means to releasibly hold the markers to the front end, second attachment means on said markers to releasibly hold the marker to the target surface, said second attachment means providing substantially greater adhesion to said target surface than said first attachment means has to said front end, whereby on impact of the dart against said target surface a marker will adhere to the target surface and the dart will release itself from the marker.
