Abstract

A ball for target games has interengaging material for detachable adherence to an interengaging fabric surface of a target. A strip of the material has at least one curved portion. The ball has spaced openings along the extent of the strip or strips, and a strip portion extends through each opening. The strip may comprise a plurality of segments. The strip material and the target interengaging fabric surface each comprises a multiplicity of interengaging elements. The strips are adhesively secured to the ball surface. The openings may comprise spaced-apart pairs of openings, each separated by a wall portion, with the strip extending through each of the openings and retained by the wall portion. In another form, end portions of adjacent strip segments extend into a single opening and are secured to the edge walls of the opening and to the adjacent interior wall surface. A groove may be defined in the ball surface of such configuration and size as to receive the strip with the interengaging surface elements thereof extending above the ball surface adjacent to the groove. The groove may be deeper on the outside of the curved portion of the strip than on the inside to reduce the circumferential extent of the strip outside edge. A plurality of spaced-apart notches or slits may be defined in the inside of the strip curved portion to reduce the effective length of the inward edge portion for improved securement of the strip.

Claims

a plurality of openings are spaced along the extent of the strip on the spherical ball surface, and

a strip portion extends through each of the openings.

3. A ball according to claim 2, wherein:

each of the first and second interengaging fabric surfaces comprises a multiplicity of interengaging elements.

4. A ball according to claim 2, wherein:

the strip material is adhesively secured to the spherical surface of the ball.

5. A ball according to claim 2, wherein:

the ball is formed of thermoplastic material by molding.

6. A ball according to claim 2, wherein:

said openings comprise spaced-apart pairs of openings, the openings of each pair being separated by a portion of the wall, and

the strip extends through each of the openings and is retained by the wall portion.

7. A ball according to claim 6, and further including:

a groove defined in the spherical surface of the ball, the groove having such configuration, width and depth as to receive the strip with the interengaging surface thereof extending above the ball outer surface adjacent to the groove.

8. A ball according to claim 7, wherein:

the groove is deeper at its edge wall on the outside edge of the curved portion of the strip than on the inside edge,

whereby the distance the outer edge portion of the strip must extend circumferentially of the ball between two points on the strip is reduced in relation to the distance the inner edge portion of the strip must extend between the same two points, whereby the effective length of the outer edge portion is reduced.

9. A ball according to claim 2, wherein:

said strip comprises strip segments in end-to-end relation on the ball surface, and

end portions of adjacent strip segments extend into the openings and are secured about respective ones of the edge walls of the openings and on the adjacent interior wall surface areas.

10. A ball according to claim 9 wherein:

the strip end portions are adhesively secured to said edge walls and to said interior wall areas.

11. A ball according to claim 9, and further including:

a groove defined in the spherical surface of the ball, the groove having such configuration, width and depth as to receive the strip with the interengaging surface thereof extending above the ball outer surface adjacent to the groove.

12. A ball according to claim 11, wherein:

the groove is deeper at its edge wall on the outside edge of the curved portion of the strip than on the inside edge,

whereby the distance the outer edge portion of the strip must extend circumferentially of the ball between two points on the strip is reduced in relation to the distance the inner edge portion of the strip must extend between the same two points, whereby the effective length of the outer edge portion is reduced.

13. A ball according to claim 2, and further including:

a groove defined in the spherical surface of the ball, the groove having such configuration, width and depth as to receive the strip with the interengaging surface thereof extending above the ball outer surface adjacent to the groove.

14. A ball according to claim 13 wherein:

the groove is deeper at its edge wall on the outside edge of the curved portion of the strip than on the inside edge,

whereby the distance the outer edge portion of the strip must extend circumferentially of the ball between two points on the strip is reduced in relation to the distance the inner edge portion of the strip must extend between the same two points, whereby the effective length of the outer edge portion is reduced.

15. A ball according to claim 2, wherein:

the curved portion of the strip has a plurality of spaced-apart notches defined in its edge portion on the inward side of the curve, said notche'"'"'s being closed to an appropriate degree, whereby the effective length of the inward edge portion is reduced in relation to the outward edge portion for improved securement of the inward edge portion of the ball surface.

16. A ball according to claim 2, wherein:

the curved portion of the strip has a plurality of spaced-apart slits defined in its edge portion on the inward side of the curve, said notches have their respective edges overlapped to an appropriate degree, whereby the effective length of the inward edge portion is reduced in relation to the outward edge portion for improved securement of the inward edge portion of the ball surface.

17. A ball according to claim 1, wherein:

the strip comprises a plurality of strip segments.

18. A ball according to claim 1, wherein:

each of the first and second interengaging fabric surfaces comprises a multiplicity of interengaging elements.

19. A ball according to claim 18 wherein:
