Abstract
A toy is provided which simulates a marine creature. The toy comprises a body portion and a tail portion with a tail fin pivotally mounted thereto; a battery operated motor housed in a water-tight compartment in the body portion to move the tail and the tail fin relative to the body portion to propel the toy through the water; a drive to drive the tail portion comprising a pair of parallel cranks mounted opposite one another on a single spindle and driven through gearing by the motor; and a drive member extending down within the top portion of the tail, the drive member being provided with a pair of slots, each slot receiving a pin connected to one of the cranks. Buoyancy may be achieved using floats located in the body and tail portions.
Claims6
A toy simulating a marine creature which comprises a body portion and a tail portion with a tail fin pivotally mounted thereto;
- a battery operated motor housed in said body portion and arranged to move said tail and said tail fin relative to said body portion to propel said toy through the water;
- a drive means to drive said tail portion comprising a pair of cranks mounted parallely and directly opposite one another on a single spindle and driven through gearing by said motor;
- and a drive member extending down within the top portion of said tail, said drive member being provided with a pair of slots, each slot receiving a pin connected to one of said cranks.
A toy simulating a marine creature having a fish-like body comprising a front body portion, a tail body portion pivotally attached to the front body portion and a tail fin pivotally mounted to the tail body portion, the tail body portion and the tail fin being pivotable about substantially parallel axes;
- a battery operated motor housed in the front body portion;
- drive means operatively coupled with the motor for pivoting the tail body portion relative to the body portion and comprising a pair of parallel cranks terminating in eccentric drive pins, and mounted opposite one another on a single spindle and driven through gearing of the drive means by said motor;
- and a drive member extending into the tail, pivotable relative to the front and tail body portions and provided with a pair of slots, each slot receiving one of the pins of said cranks, whereby activation of the motor with the toy in water pivots the body portion relative to each other in a first direction and causes relative pivotal movement between the tail body portion and the tail fin in a second, opposite direction.
