1. Field of the Invention
The present invention relates to equipment for servicing skis, and more particularly, to a ski holder for tuning skis.
2. Related Art
In the sport of skiing, it is often necessary to adjust and maintain (“tune”) ski equipment. In large part, such maintenance is required as a result of mechanical stress and wear to skis which occurs over time. For example, ski edges become dull over time and require sharpening to maintain optimal performance. Similarly, ski bottoms can become scraped and gauged, and it is desirable to periodically restore them to smooth surfaces.
To adjust and maintain skis, it is necessary to properly support a ski while work is being performed. Specifically, it is important for a ski to be easily engaged by the support and held firmly in place when maintenance work is being performed, particularly when a ski is being sharpened. Unfortunately, existing ski support systems do not adequately accommodate a wide variety of ski shapes, sizes, and designs, while firmly supporting skis and while allowing for easy engagement by the support.
Accordingly, what would be desirable, but has not yet been provided, is a ski holder which addresses the foregoing limitations of existing ski support systems.
The present invention relates to a ski holder for tuning skis. The device allows a ski to be held in a variety of orientations so that adjustments and maintenance work can be performed on a ski. The device includes a track assembly, a plurality of ski support assemblies slideably engageable with the track assembly, and a plurality of binding support assemblies slideably engageable with the track assembly. The support assemblies allow skis of different shapes, sizes, and designs to be held and supported. The ski support assemblies allow a ski to be held in vertical, horizontal, and angled positions, and can be locked in desired positions along the track assembly. The binding support assemblies contact bindings of a ski to assist with retaining the ski on the ski holder, and can also be locked in desired positions along the track assembly. The device can be disassembled to allow for storage and/or transportation of the device.
The foregoing features of the invention will be apparent from the following Detailed Description of the Invention, taken in connection with the accompanying drawings, in which:
The present invention relates to a ski holder which allows a ski to be held in a variety of orientations so that adjustments and maintenance work can be performed on a ski. The device includes a track assembly, a plurality of ski support assemblies slidably engageable with the track assembly, and a plurality of binding support assemblies slidably engageable with the track assembly. The ski support assemblies allow a ski to be held in vertical, horizontal, and angled positions, and can be locked in desired positions along the track assembly. The binding support assemblies contact bindings of a ski to assist with retaining the ski on the ski holder, and can also be locked in desired positions along the track assembly.
A depending track engagement projection 28 and a depending track guide tab 30 are provided on the bottom wall 25 to facilitate slideable engagement between the ski support assembly 14 and the track assembly 12, as will be discussed. The tab 30 includes an aperture 33 which receives a set screw 32 that extends into a channel along an edge of the track assembly 12 for selectively locking the support assembly 14 in a desired position along the track assembly 12. A nut 34 positioned within the channel threadably engages the set screw 32 and bears against the track assembly 12 to hold the support assembly 14 in a fixed position when the set screw 32 is tightened by a user. The depending track engagement projection 28 could be angled with respect to the bottom wall 25, as shown, slides along a corresponding channel formed in the track assembly 12, and is shaped so as to prevent the support assembly 14 from detaching from the track assembly 12 when slideably engaged therewith. These features work together to limit the relative movement of the support assembly 14 with respect to the track assembly 12 during use.
The transverse upper wall 36 of the support assembly 14 provides a surface against which a ski can be placed in a horizontal position. Additionally, the angled wall 38 provides a surface against which a ski can be placed in an angled position. A support finger 40 is provided at the lower end of the angled wall 38 and includes a bearing surface and retaining surfaces at right angles to each other for receiving a side of a ski to support a ski against the angled wall 38. An angled cushion 42, which includes an upright portion 44, a transverse portion 46, an angled portion 48, and a finger portion 50, is attached to the support assembly 14 for contacting a ski and to prevent damage to the ski when the ski is being held by the present invention. The cushion 42 need not be provided in one piece, e.g., a plurality of separate cushions could be provided for covering the surfaces shown in
The support assembly 14 includes a clamp assembly 52 for holding a ski in a generally vertical position. The clamp assembly 52 includes a rounded bottom projection 54, an upright wall 56, a set screw 62, and a biasing spring 60 disposed coaxially about the set screw 62. The set screw 62 threadably engages threaded aperture 66 in upright wall 26b. When the set screw 62 is tightened by a user, the clamp assembly 52 is drawn toward the upright wall 26b of the support assembly 14 to provide a clamping action for holding a ski in a vertical orientation. A transverse projection 67 on upright wall 26b ensures proper alignment of the clamp assembly 52. The bottom rounded projection 54 contacts a rounded recess 65 so as to provide a smooth, rolling motion of the clamp assembly 52 toward the upright wall 26b when the set screw 62 is tightened. Additionally, when the set screw 62 is tightened, a cushion 64 on the upright wall 56 is angled toward upright wall 26b to contact and securely hold a ski in position. A second transverse projection 69 on the upright wall 26b supports a ski as it is inserted in the clamp assembly 52.
As shown in
The lower transverse wall 85 includes a depending track engagement projection 96 and a depending track guide tab 98 which facilitate slideable engagement between the binding support assembly 16 and the track assembly 12. The track engagement projection 96 could be angled with respect to the wall 85, as shown, slides along a corresponding channel formed in the track assembly 12, and is shaped so as to prevent the binding support assembly 16 from detaching from the track assembly 12 when slideably engaged therewith. The tab 98 includes an aperture 102 which receives a set screw 100 that extends into a channel along an edge of the track assembly 12 for selectively locking the binding support assembly 16 in a fixed position along the track assembly 12. A nut 104 positioned within the channel threadably engages the screw 100 and bears against the track assembly 12 when the screw 100 is tightened, so as to retain the binding support assembly 16 in a fixed position. These features work together to limit the relative movement of the binding support assembly 16 with respect to the track assembly 12 during use. As shown, the adjustable contact pad 92 could be concave in shape to accommodate the end of a binding to inhibit lateral movement of a ski. The pad 92 could include a cushioning 93 formed of rubber, plastic, foam, etc., to prevent damage to a ski binding and to inhibit movement of the ski.
As shown in
It is also noted that a stabilization assembly can be provided for each of the support assemblies 14 and 16 to assist with movement and alignment of the assemblies 14 and 16 along the track assembly 12 and to prevent excessive “chattering” of the assemblies 14 and 16 as they slide along the track assembly 12. Such a stabilization assembly could include a pair of washers formed from an anti-friction material (including, but not limited to, ultra-high molecular weight (UHMW) polyethylene or acetyl resin engineered plastic (e.g., DELRIN brand plastic manufactured by DuPont, Inc.)) and a spring or other bias positioned between the washers to urge them against the channel formed in the track assembly 12 when the set screws 32 and 100 are untightened. The spring and washers can be disposed coaxially about the set screws 32 and 100, and one of the washers positioned on one side of the spring. The opposite side of the spring can contact the nut 34 or 104, and the remaining washer can be positioned between the nut 34 or 104 and the side wall 128 of the channel. As the set screws 32 and 100 are untightened, the spring urges the washers against the sides of the channel so as to allow the support assemblies 14 and 16 to slide along the track assembly 12 while reducing chattering. Of course, different components and/or materials could be implemented without departing from the spirit or scope of the present invention.
Although use of the present invention was discussed herein in connection with Nordic skis, it is noted that the present invention could also be used (as is, or with minor modifications) to tune cross-country skis and snow boards.
Having thus described the invention in detail, it is to be understood that the foregoing description is not intended to limit the spirit or scope thereof. What is desired to be protected is set forth in the following claims.
