## Abstract

The invention is concerned with a marker for the anchoring device of a captive ball and cord in a game comprising a spiral mounted on a stand and a ball on a cord, the other end of which is associated with the spiral for relative movement therewith according to the direction in which the ball is hit, the marker providing a prominent visual indication to the players of the game of the location of the anchoring device relative to the spiral; the marker optionally serving to hold the cord to the spiral.

## Claims

### Claim 1

An anchoring device for a captive ball and cord in a game comprising a stand supporting a spiral and a ball on one end of a cord, means interconnecting the other end of the cord and the spiral for vertical movement of said spiral and said other end of the cord relative to each other upon rotation of the ball around the stand, and an enlarged member on said other end of said cord adjacent but outside said spiral, said enlarged member having a diameter greater than the distance apart of the coils of the spiral so as to prevent the cord from becoming snagged in the coils of the spiral and to provide a prominent visual indication to the players of the game of the relative position of the cord and the spiral.

### Claim 2 (depends on 1)

An anchoring device as claimed in claim 1, in which said enlarged member comprises a hollow conical ferrule adapted to receive a knot of the doubled-back end of the cord in wedging relationship.
