A ski having vents for venting snow from beneath the ski to a location above the ski and a modified keel that provides for greater and easier directional control over the ski relative to a conventional ski.
Claims20
1:
- A vent adapted for use in venting snow through a ski, the vent comprising:
- a top surface and a bottom surface that are connected to one another by an inner sidewall and an outer sidewall, a front end and a back end that is at least partially open, the bottom surface having an opening that allows snow to enter the vent and an exhaust opening that allows snow to exit the vent;
- and
- wherein the vent is insertable in or attachable to the ski.
1 more element
2:
- The vent of claim 1, further comprising a blade that extends beneath a bottom surface of the ski and provides greater directional control over the ski.
3:
- The vent of claim 1, wherein the exhaust vent is an opening in the back end of the vent and the front end is closed.
4:
- The vent of claim 1, wherein the exhaust vent is an opening in the inner side wall.
5:
- The vent of claim 1, wherein the exhaust vent is an opening in the outer side wall.
6:
- The vent of claim 1, further comprising a directional guide member affixed to either the inner sidewall or the outer sidewall.
7:
- A vented ski for a ski-mounted vehicle that vents snow from a ground surface as the ski-mounted vehicle travels along the ground surface, the vented ski comprising:
- a ski body having a leading end, a trailing end, a top ski surface and a bottom ski surface that is a glide surface;
- one or more vents, each vent having a top surface and a bottom surface that are connected to one another by an inner sidewall and an outer sidewall, a front end and a back end that is at least partially open, the bottom surface having an opening that allows snow to enter the vent and an exhaust opening that allows snow to exit the vent;
- and
- wherein each of the one or more vents is inserted into or attached to the ski.
2 more elements
8:
- The vented ski of claim 7, wherein at least one of the one or more vents is affixed to the outside of the ski body.
9:
- The vented ski of claim 7, further comprising the ski body having one or more openings, and wherein each of the one or more vents is positioned within each of the one or more openings.
10:
- The vented ski of claim 9, wherein at least a portion of the exhaust opening is in the outer sidewall so as to cause snow to exits the vented ski to exit in a direction away from the ski-mounted vehicle.
11:
- The vented ski of claim 9, wherein at least a portion of the exhaust opening is in the inner sidewall so as to cause snow that exits the vented ski to exit in a direction towards a track on the ski-mounted vehicle.
12:
- The vented ski of claim 9, further including a keel that has a length that is less than approximately 30% of the length of the ski body.
13:
- The vented ski of claim 9, further including a keel that has a length that is less than approximately 20% of the length of the ski body.
14:
- The vented ski of claim 9, further including a keel that has a length that is between approximately 6 inches and approximately 14 inches in length and that has a depth of between approximately 2 inches and approximately 4 inches.
15:
- The vented ski of claim 9, wherein each of the one or more vents has a blade that extends beneath a bottom surface of the ski body.
16:
- A ski having a modified keel, the ski comprising:
- a ski body having a leading end and a trailing end, and a bottom surface that is the ski glide surface;
- and
- a keel affixed to the bottom surface, the keel having a length that is less than approximately 30% of the length of the ski.
1 more element
17:
- The ski of claim 16, wherein the keel has a length that is less than approximately 20% of the length of the ski.
18:
- The ski of claim 16, wherein the keel has a length between approximately 6 inches and approximately 14 inches and having front and back ends that are tapered, and having an approximately flat section between the front and back ends that is between approximately 6 inches and approximately 10 inches in length, the keel further having depth that is between approximately 2 inches and approximately 4 inches.
19:
- The ski of claim 18, wherein the keel has a length between approximately 10 inches and approximately 12 inches in length and wherein the flat section between the tapered section is between approximately 5 and 7 inches in length.
20:
- The ski of claim 16, further including two sides on the flat section of the keel that form a channel.
