APPARATUS FOR SHARPENING OF SKVSNOWBOARD
METAL EDGES
BACKGROUND OF THE INVENTION
This invention relates to an improved apparatus for holding a file or the like (such as polishing/cutting devices) in a selected fixed position and angle relative to a ski or snowboard metal edge thus allowing the user to perform the 10 operation of sharpening either the ski/snowboard side edge or base edge at a given bevel angle accurately and consistently.
Until recently, ski designs have had a conventional side-cut (a turning radius of between 30 and 40 metres). With the recent increase in popularity of "shaped" or "super side-cut" skis, side cut has become more pronounced 15 whereby a ski is more narrow in the waist than it is in the shovel and the tail, making it easier to carve a turn (a turning radius of between 10.5 and 30 metres). This is relevant as up until recently it has been possible to sharpen and bevel a ski with conventional side-cut by positioning a file lengthwise on a guide to sharpen and bevel the side edge. This is not the best position to place20 the file however, as with even a small amount of side-cut, the teeth of the file only contact the edge at two places along the length of the file (front and back).
This is even more pronounced with shaped skis, making the sharpening/bevelling job difficult and inefficient at best. U.S. Patent 4,030,382 to Nilsson et al shows an attempt to compensate for this by using a clamping 25 screw to bend a file blade between two support ribs.
A further factor is that the inherent angle of the teeth on a file when positioned lengthwise on the metal edge does not produce the best cut when the file is pulled along the length of the edge. It is when the file is rotated somewhat that a better and more efficient cut is achieved (the file teeth are ' CA 02202723 1997-04-1~
better oriented in relation to the direction of the cut along the edge).
SUMMARY OF THE INVENTION
It is the main object of this invention to provide a ski/snowboard edge treating system that is inexpensive, portable and easy to use while minimi7ing 5 the fatigue and effort required to perform an accurate and consistent edge sharpening/bevelling job especially on "shaped" or "super side-cut" equipment as described above.
Accordingly, the invention in one aspect provides a file holder for holding a file or the like in a selected position and angle relative to a ski or10 snowboard metal edge to enable sharpening/bevelling of either the ski or snowboard metal side edge or base edge at a selected bevel angle, said holder including a guide adapted to be held by the hand and moved lengthwise along a ski or snowboard in contact with a surface thereof, and means for securing a file or the like to said guide at any one of a plurality of angular positions such 15 that in use a desired portion of the file length may make contact with the metal edge portion of the ski or snowboard thus assisting in producing a consistent file cut and efficient edge sharpening/bevelling regardless of the degree of shaping or side cut of the ski or snowboard.
Because the file/polishing/cutting device can be positioned at an angle to 20 the guide enabling only a relatively small portion of the file length to makecontact with the metal edge portion of the ski or snowboard, the life of the file is greatly extended, as many different portions of the file can be utilized. This is not the case with conventional file guides that hold the file lengthwise in apredetermined position where a maximum of four small surface areas are 25 usable (assuming both sides of commercially available files or other polishing or cutting devices are used).
In order to enable the file to be positioned at an angle so that only a relatively small portion of the file length makes contact with the metal edge atone end of the guide, one embodiment provides a metal washer which is ' CA 02202723 1997-04-1~
interchangeably mounted at either end of one side of a height-adjustable clamp plate to prevent the guide from falling off the edge when filing/polishing/cutting. The other side of the clamp plate does not have provision for such a washer in order to allow for the file to be placed in the guide length-wise.
Because the file/polishing/cutting device is clamped in position between the underside of a top portion of the guide body and the height-adjustable clamp plate, the file remains flat through its length. As a result the edge bevel angle achieved is more precise than can be achieved by bending the file (see Nilsson et al) as a clamping screw distorts the underlying file teeth.
A substantial number of commercially available files/polishing/cutting devices can be employed by the file guide. In other words, the same guide can be used for honing, deburring, polishing as well as rough and smooth filing.
Two or more segments of files/polishing/cutting devices are able to be clamped in the file guide at one time in order to perform more than one operation in a single pass down the length of the ski/snowboard metal edge (i.e.a segment of file cuts the edge while a segment of whetstone polishes the edge simultaneously). This includes the ability to place a module combining two or more segments into the guide as a single unit.
The file guide is designed so that the file is not placed on the upper surface of an angular member as in U.S. Patent 4,721,020 to Stumpf. Rather it is clamped to the underside of a top portion of the guide body by means of the height-adjustable clamp plate, as noted above. By clamping the file in this way,a special 'chip receiving recess or slot' is not necessary as there is a void under the plate where metal filings can escape from the file without the possibility of building-up between the file guide surface which engages the ski/snowboard base and the ski/snowboard base during a sharpening operation. As a result, no filings have the possibility to become embedded in the plastic base of the ski/snowboard as is often the case when using a file on a prior art angular CA 02202723 1997-04-1~
member with or without a 'chip receiving recess'.
Another feature of the invention employs the use of interchangeable dowels or pegs to achieve a desired edge bevel angle. By selecting the lengths of dowels or pegs which project outwardly from the guide and engage the 5 ski/snowboard base, a more precise bevel angle can be achieved as compared with the eccentric disc system employed by Leitinger (DE 3233683 A1) to achieve a selected edge bevel angle, which system out of necessity, comprises moving parts, and general wear and tear can cause the angle to vary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring first to Fig. 1 which illustrates a file being used, there is shown the file guide main body 1 which clamps a file or other implement 2 in a fixed position relative to the main body 1 and, during use, to the edge of the ski/snowboard edge to be tuned. A wide variety of sizes and types of ' CA 02202723 1997-04-1~
cutting/polishing implements 2 can be clamped in the guide including rough (panzer) files, smooth (mill) files, x-course, course, fine, and extra fine diamond whetstones, deburring stones etc. as well as combination of cutting and/or polishing implements (i.e. a segment of file cuts the edge while a 5 segment of whetstone polishes the edge simultaneously). This allows the file guide to be used for a variety of operations including honing, deburring, polishing as well as rough and smooth filing. Further, the cutting/polishing implement 2 when extending through a slot lC just below top portion lA of the main body can be rotated and clamped at any angle such that only a small 10 portion of the implement 2 makes contact with the metal edge.
A washer 3, preferably made of stainless steel, is fastened to an end portion of a top plate of a height-adjustable 'T' clamp 4 and acts as a wear plate and guide directly above the ski/snowboard edge in order to stabilize the guide and prevent the end of the guide from falling down under the edge.
15 Countersunk on the corners ofthe 'T' clamp top plate are smaller stainless steel washers 12 that act as wear plates when the guide is run along the length of theski/snowboard, thus preventing the side surface of the 'T' clamp 4 from wearing down as a result of contact with the ski/snowboard edge. Both washer 3 and washers 12 are fastened to the 'T' clamp top plate 4 by nut 13 and bolt 20 14. The washer 3 can be interchangeably mounted on either end of the height-adjustable T-clamp 4 so that both right and left-handed users can use the guide comfortably. The wide underside of the top portion lA of the main body 1 acts as a horizontal plate against which the cutting/polishing implement 2 is clamped by the action ofthe 'T' clamp 4. A thumb screw 10 threaded into a 25 square nut 11 (captivated in the wall between the main body 1 and cover 8) isturned in order to adjust the height of the 'T' clamp 4 relative to main body 1 thereby allowing cutting/polishing implements 2 of varying thicknesses to be clamped between the underside of the top portion lA of the main body 1 and the top plate of 'T' clamp 4.
~ . CA 02202723 1997-04-1~
With reference to Fig. 2, it is seen that the guide has the ability to clamp a cutting/polishing implement 2 lengthwise on either side of the main body 1 between the 'T' clamp 4 and the underside of top portion lA, if the user preferssuch an orientation, as well as in a number of angular positions as shown in Fig.
5 3 . Pairs of cylindrical holes 5 in the top portion lA of the main body 1 serve to store a number of sets of pegs 6, with two identical pegs constituting a set. Inaddition, fixed pegs 7 are moulded as one piece onto the face of cover plate 8 which is secured by screws to the lower portion lB of the main body 1. These fixed pegs 7 serve to angularly orient the guide when, in use, it is run along the 10 base ofthe ski/snowboard and to set the side edge geometry (angle) at 90 degrees.
The height-adjustable 'T'clamp 4 is secured in place by cover 8 in the lower portion lB between cover 8 and a rear wall portion 8A integrally formed with lower portion lB ofthe main body. 'T' claim 4 has integrally attached as 15 one piece a spaced pair of lower hollow cylinders 9 to receive the sets of pegs 6 so that the pegs 6 move in concert with the 'T' clamp 4. Cylinders 9 project through slots 9A in the cover 8. The sets of pegs 6 are preferably made of a plastic material with good memory and wear characteristics (nylon, Teflon etc.) and can be easily snapped into place and removed from the cylindrical holes 5 20 in the top portion lA of the main body 1 and also snapped into or removed from the lower cylinders 9 of 'T' clamp 4. All sets of pegs 6 are longer than the fixed pegs 7 when placed in the lower cylinders 9. Each set of pegs 6, like the fixed pegs 7, serves to angularly orient the guide when placed against the base of a ski/snowboard as shown in Fig. 5 and to provide an accurate and 25 specific bevel angle (the bevel angle is dependent on the length of each set of pegs 6) while also providing a void or gap where debris such as metal filmgs and side edge material can fall away from the ski/snowboard. Further, the sets of pegs 6 can be placed in the lower cylinders 9 on either side of the guide depending on preference.
~ . CA 02202723 1997-04-1~
As seen in Fig. 3, the cutting/polishing implement 2 when extending through slot lC can be oriented and clamped in any number of angular positions relative to the guide main body 1 and, in use, to the metal edge of the ski/snowboard.
Fig. 4 illustrates how the lengths of pegs 6 can vary in order to establish a variety of different bevel angles. Fig. 5 illustrates how either the fixed pegs 7 or a selected set of pegs 6 determine the edge bevel angle based on the length of pegs. The longer the pegs of each set that are used, the greater the bevel angle.
The lengths of the sets of pegs 6 are chosen to provide desired angular increments, e.g. 1.0 degree over a desired range, e.g. 91.0 to 96.0 degrees.
A preferred embodiment of the invention has been described by way of example. Those skilled in this art will realize that numerous modifications and adjustments may be made while still remaining within the spirit and scope of the invention as set out more particularly in the appended claims.
