Abstract
The present invention provides an ice shaver with a power control drive system to rotate the ice block and blade with respect to one another and to press the ice block and the blade together. The power drive system comprises an in-line, over-center, linear throw column extending through an opening in an enclosure and carrying a spike plate. A motor is carried by and contained within the column and movable with the column toward a shave deck with a blade. A perimeter size and shape of the column matches a perimeter size and shape of the opening. The column substantially closes the opening in the enclosure.
Claims20
An ice shaver configured to shave ice, the ice shaver comprising:
- a substantial enclosure configured to receive an ice block;
- a shave deck with a blade at one end of the enclosure;
- a spike plate in the enclosure opposite the shave deck and movable towards the shave deck and rotatable with respect to the shave deck;
- an opening in the enclosure opposite the shave deck;
- a column extending through the opening in the enclosure and carrying the spike plate, the column and the spike plate movable linearly towards the shave deck;
- a motor carried by and contained within the column and movable with the column toward the shave deck, the motor coupled to the spike plate to rotate the spike plate with respect to the shave deck;
- a perimeter size and shape of the column matching a perimeter size and shape of the opening;
- and
- the column substantially closing the opening in the enclosure.
An ice shaver configured to shave ice, the ice shaver comprising:
- a shave deck with a blade;
- a top deck opposite the shave deck and fixed with respect to the shave deck;
- an opening formed in the top deck;
- a guard substantially circumscribing a gap between the top deck and the shave deck;
- a column extending through the opening in the enclosure and movable linearly towards the shave deck;
- a perimeter size and shape of the column matching a perimeter size and shape of the opening;
- the column substantially closing the opening;
- the shave deck, the guard, the top deck and the column defining a substantial enclosure configured to receive an ice block;
- a spike plate in the enclosure opposite the shave deck and carried by the column, the spike plate being movable with the column towards the shave deck, and the spike plate being rotatable with respect to the shave deck and configured to rotate the ice block with respect to the blade;
- and
- a motor carried by and contained within the column and coupled to the spike plate to rotate the spike plate.

- a shave deck with a blade;
- a top deck opposite the shave deck and fixed with respect to the shave deck;
- an opening formed in the top deck;
- a guard substantially circumscribing a gap between the top deck and the shave deck;
- a column extending through the opening in the enclosure and movable linearly towards the shave deck;
- a perimeter size and shape of the column matching a perimeter size and shape of the opening;
- the column substantially closing the opening;
- the shave deck, the guard, the top deck and the column defining a substantial enclosure configured to receive an ice block;
- a spike plate in the enclosure opposite the shave deck and carried by the column, the spike plate being movable with the column towards the shave deck, and the spike plate being rotatable with respect to the shave deck and configured to rotate the ice block with respect to the blade;
- a motor carried by and contained within the column and coupled to the spike plate to rotate the spike plate;
- a power supply carried by the column and comprising an electrical transformer configured to be coupled to an external power source;
- a motor control switch carried by the column and electrically coupled to the power supply, the power control switch being operable to activate the motor, and the power control switch movable with the column;
- a gear box carried by and contained within the column and coupled between an output shaft of the motor and the spike plate;
- and
- a combined weight of the column, the motor, the gearbox, the power supply, and the spike plate configured to press the ice block against the blade of the shave deck.
