Abstract
A ski sharpening arrangement includes a portable powered grinder adapted to be manipulated by one hand of a user. The arrangement includes a motor assembly spaced from a ski having a top surface, a base, a side edge and a bottom edge coplanar with the base. The motor assembly drives an endless belt having an abrasive surface about an axis of rotation transverse to a plane of the base. The endless belt is entrained about a mounting framework extending from the motor assembly, and engaged against the side edge of the ski to provide sharpening thereof. A support structure is suspended from the mounting framework of the belt and is adapted to be manipulated by another hand of the user for guiding, stabilizing and changing the angle of the abrasive surface relative to the side edge of the ski.
Claims17
A side edge ski sharpening arrangement for sharpening a ski having a top surface, a base, a pair of side edges and a bottom edge coplanar with the base, comprising:
- a portable, powered grinder adapted to be manipulated by one hand of the user and including a motor assembly for driving an endless belt having an abrasive surface defining a substantially flat plane of abrasion, the endless belt being entrained about a mounting framework extending from the motor assembly and rotatable about an axis generally perpendicular to the base of the ski, wherein the abrasive surface is engageable against the side edge of the ski to provide sharpening thereof;
- and
- a support structure suspended from the powered grinder and alignably positioned with the plane of abrasion to continuously contact the base of the ski along an entire length thereof to guide the abrasive surface relative to the side edge of the ski, wherein the support structure is adjustable to control the angle of the plane of abrasion relative to the base of the ski.
A ski side edge sharpening arrangement for sharpening a ski having a top surface, a base, a pair of side edges and a bottom edge coplanar with the base, comprising:
- a portable, powered grinder adapted to be manipulated by one hand of a user and including a motor assembly for driving an abrasive surface having a substantially flat plane of abrasion, wherein the abrasive surface is rotatable about an axis generally perpendicular to the base of the ski and is constantly engageable with the side edge of the ski to provide sharpening thereof;
- and
- a support structure suspended from the powered grinder and adapted to be manipulated by another hand of the user for constantly guiding the abrasive surface along the side edge of the ski along an entire length thereof, the support structure comprising:
- a roller assembly having a guide roller engageable against the base of the ski and a fixed support shaft about which the guide roller rotates, and
- an adjustment device fixed to the powered grinder, the adjustment device being tiltably mounted relative to the support shaft such that the adjustment device is adjustable to control the angle of the plane of abrasion relative to the base of the ski.
