Description
WIDE ICE RESURFACING MACHINE
Field of the Invention The present invention relates to ice resurfacing machine. In particular, the present invention relates to ice resurfacing machine having the capacity to resurface a wider surface of ice than a traditional ice resurfacing machine.
Background Ice resurfacing machines, often referred to as "zambonis", are well known and are typically used to resurface hockey rinks, skating arenas and other ice surfaces. These consist generally of a vehicle on which an ice resurfacing unit is installed at the back end, so that as the operator drives the vehicle on the ice, a trail of clean ice with a thin film of water is left behind.
In the prior art, the width of the resurfacing unit is typically the width of the vehicle.
This means that an operator of an ice resurfacing machine must drive over every square inch of the ice surface, a process which can take as much as 10 minutes on a regular sized hockey rink. For larger ice surfaces, such as for example, the Rideau Canal in Ottawa, Ontario, this problem is compounded, as the cost of operating an ice resurfacing machine for the time it takes to resurface the entire ice surface can be prohibitive.
Thus, there is a need for an ice resurfacing machine which can resurface a larger amount of ice at a time.
Summary of the Invention According to at least one embodiment of the present invention, there is provided an ice resurfacing machine having a resurfacing unit with a width which is greater than the width of the machine.
According to at least another embodiment, there is provided an ice resurfacing machine having an arm extending from one side of the machine, the arm comprising a resurfacing unit.
According to at least another embodiment, there is provided an ice resurfacing machine having an arm extending from both sides of the machine, both arms comprising a resurfacing unit.
In the above described embodiments, the arms, or the wide resurfacing units can be in a deployed configuration or in a folded configuration. In the folded configuration, the arms are essentially parallel to the vehicle, thereby allowing the ice resurfacing machine to drive through narrow passageways, such as the gate of a hockey rink. In the deployed configuration, the arms are extended sideways for operation.
The ice resurfacing units are of the conventional type. In particular, in at least one embodiment, the ice resurfacing units comprise a scraper, a water delivery system, and a squeegee which spreads the water evenly over the ice surface.
According to at least one embodiment, the arms also comprise an auger which collects the ice shaved by the scraper, and transports it to a holding container, where it can be melted into water which can be used by the ice resurfacing machine.
According to at least another embodiment, advantageously designed for outdoor use, the water delivery system further includes heating elements to ensure that the water is not frozen prior to use.
Brief Description of the Drawings The present disclosure will be better understood with reference to the drawings in which:
Figure 1 is an elevated view of a vehicle in accordance with one embodiment of the present disclosure operating on an ice surface.

The grayed out portion 18 shows the ice surface already resurfaced by machine 12. As can be seen from Figure 1, arm 16 extends all the way to a dotted line 13 at the center of the ice. Therefore, if the machine 12 follows the trajectory defined by dotted line 11, the entire ice surface can be resurfaced in just one lap of the machine 12. As would be appreciated by those skilled in the art, the area 17 will be resurfaced by the conventional ice resurfacing unit 14 and the area 15 will be resurfaced by the arm 16.
Figure 2 shows an embodiment of the present invention having two arms 24 and extending sideways from the ice resurfacing machine 22. As can be seen from Figure 2, in this embodiment, both arms meet at a point behind the machine 22 so that there are no gaps in the resurfaced ice (shown by numeral 28).
In some embodiments, the present invention also includes an ice safety mechanism, to ensure that the ice is thick enough to support the weight of the vehicle.
It should be appreciated that the present invention may be practiced to achieve any width desired. In one embodiment, the operative width of the ice resurfacing machine is 150 feet, however this is not limiting and even greater widths can be achieved.
These two arms can also include a blade, a water delivery system, a squeegee, and optionally an auger to collect ice shavings. Water can be provided to the water delivery system via pipes or hoses. In at least one embodiment, heating elements are provided near the pipes to prevent the water from freezing before it is used.
Depending on their length, the arms may fold at a single point, or at multiple points. As would be appreciated by those skilled in the art, if the arms have a length which is approximately equal to or less than the length of the vehicle, they may fold at a single point near the rear of the vehicle. If however the arms are longer than the vehicle, it is preferable to fold the arms at more than one point, so that any individual segment is not substantially longer than the length of the vehicle.
