Mechanical surf board

Claim 2

A mechanical surfing apparatus comprising an elongated surf board, means for supporting and moving said board in such a manner as to simulate movement under actual surfing conditions, said supporting and moving means comprising an elongated support beneath said surf board, means mounting said board on said support for transverse pivotal movement about a longitudinal axis, power means connected to said support adjacent one end thereof for moving the same in a circular path about a first transverse axis extending crosswise of said board, a generally upright rod pivoted at its upper end to said support adjacent the other end of said support on an axis parallel to said first transverse axis, said rod being pivoted at its lower end to a base on an axis parallel to said first transverse axis, and means for locking said board in adjusted position about said longitudinal axis.

Claim 3

A mechanical surfing apparatus comprising an elongated surf board, means for supporting and moving said board in such a manner as to simulate movement under actual surfing conditions, said supporting and moving means comprising an elongated bar extending beneath said surf board lengthwise thereof, means mounting said board on said bar for transverse pivotal movement about a longitudinal axis, a bracket rigid with and depending from said bar adjacent one end of said board, power means for moving said bracket in a circular path about a first transverse axis extending crosswise of said board, a generally upright rod pivoted at its upper end to said bar adjacent the other and of said bar on an axis parallel to said first transverse axis, said rod being pivoted at its lower end to a base on an axis parallel to said first transverse axis, and means for locking said board in adjusted position about said longitudinal axis.

Claim 4

A mechanical surfing apparatus comprising an elongated surf board, means for supporting and moving said board in such a manner as to simulate movement under actual surfing conditions, said supporting and moving means comprising an elongated bar extending beneath said surf board lengthwise thereof, means mounting said board on said bar for transverse pivotal movement about a longitudinal axis, a bracket rigid with and depending from said bar adjacent one end of said board, power means for moving said bracket in a circular path about a first transverse axis extending crosswise of said board, a generally upright rod pivoted at its upper end to said bar adjacent the other and of said bar on an axis parallel to said first transverse axis, said rod being pivoted at its lower end to a base on an axis parallel to said first transverse axis, and means for locking said board in adjusted position about said longitudinal axis.

Claim 5

A mechanical surfing apparatus as defined in claim 2, wherein said locking means comprises a strut having its upper end connected to said board and its other end connected to said rod.

Claim 6

A mechanical surfing apparatus as defined in claim 3, including means for adjusting the length of said strut.

Claim 7

A Mechanical surfing apparatus as defined in claim 3, including means for connecting said other end of said strut to said rod at selected points along the length of the latter.

Claim 8

A mechanical surfing apparatus as defined in claim 3, wherein the upper end of said strut is connected to said board for pivotal movement about two axes at right angles to said strut and at right angles to each other, and the other end of said strut is connected to said rod for pivotal movement about two axes at right angles to said strut and at right angles to each other.

Claim 9

A mechanical surfing apparatus as defined in claim 6, wherein said strut is made of two overlapping sections of the strut to be varied, and a collar connecting said other end of said strut to said rod at selected points along the length of the latter.
