Abstract
A holder for the shaft or pole of a signal pole used in boats to indicate that an occupant of the craft, or a water skier being towed by the craft, is in the water. The holder is comprised of a pair of relatively rotatable disk-like members, the first of which is attached to the boat, and the other of which is rotatably secured thereto. The second member receives a flag pole or shaft and as the member rotates the shaft is moved between a vertical operative position and a horizontal inoperative position. Automatic stop means control the rotation so as to readily position the shaft in said two positions.
Claims5
A holder for a signal flag, including:
- a first generally planar member;
- means for attaching said first member to a supporting structure;
- a second generally planar member;
- means securing said second member to said first member for rotation about an axis generally normal to the plane of said members;
- said second member having means for holding therein a signal flag shaft so that the shaft is moveable in a plane generally normal to the rotational axis between a raised first signal position and a lowered second storage position as said second member is rotated about said axis with respect to said first member;
- said second member is rotated about said axis with respect to said first member;
- said second member having a rib extending outwardly from the face of said second member opposite from said first member, extending diametrically with respect to and perpendicular to said axis to constitute handle means for manually rotating said second member with respect to said first member;
- said rib further having a blind bore perpendicular with respect to said axis and longitudinally with respect to said rib, and constituting said means for holding a signal flag shaft;
- said means adapted for attaching said first member including at least two bores parallel to and spaced from said axis extending through said first member for receiving therein threaded means to engage the supporting structure;
- and said second member having through bores aligned with respective ones of said first member through bores in one rotated position of said second member with respect to said first member and being of a diameter substantially larger than the diameter of said first member bores for completely passing therethrough said threaded members and a driver tool for rotating said threaded members.

A holder for a signal flag, including:
- a first generally planar member;
- means for attaching said first member to a supporting structure;
- a second generally planar member;
- means securing said second member to said first member for rotation about an axis generally normal to the plane of said members;
- said second member having means for holding therein a signal flag shaft and moving the shaft in a plane generally normal to the rotational axis between a raised first signal position and a lowered second storage position as said second member is rotated about said axis with respect to said first member;
- one of said members having an arcuate through slot concentric with respect to said axis;
- a headed member extending through said arcuate slot and being rigidly received within the other of said members at one end and having its head at its opposite end on the opposite side of said slot from said other member;
- a plurality of enlarged recesses along said slot and opening axially away from said other member and of a size for receiving therein said head, to constitute means for positively preventing relative rotation of said first and second members about said axis when said head is received within one of said recesses and permitting free relative rotation of said first and second members about said axis when said head is axially spaced from said recesses;
- said securing means mounting said first and second members for limited axial movement with respect to each other for at least a distance sufficient to permit engagement of said head within one of said recesses in one position and to provide axial spacing between said head and said recesses in an other position;
- spring means biasing said first and second members away from each other and into said one position, and elastically yielding upon movement of said first and second members axially from said one position to said another position.

- said securing means mounting said first and second members together for limited axial movement with respect to each other between a first position and a second position;
- axially interengaging means between said first and second members for preventing relative rotation in said first position and freely permitting relative rotation in said second position;
- spring means biasing said first and second members into said first position, and comprising a plurality of axially extending blind bores in one of said members opening towards the other of said members, a compressed coil spring receiving within each of said blind bores;
- a bearing material plunger partially received within each of said blind bores for engaging at one axial end the respective coil spring and engaging at its other axial end the adjacent face of the other of said members.
