2. Description of Prior Art Skiing has fast become one of the worlds most popular sports. In almost every country the popularity of this sport gains substantially each year. In the United States, its fast growth has given rise to an important in dustry which has become highly competitive. Manufacturers of ski related equipment are continuously seeking innovations which will enable them to gain a favorable edge over competitors in the market. Improvements in skis, boots, bindings, poles and other equipment have been the focal point of the manufacturers attention. As a result, skiing equipment and the sport itself have reached a new level of success.
There is, however, still a need for further improvement in some of the ski equipment now used. For example, it is essential that the skier clean the sole of his boot prior to stepping into his binding so that the boot will not be snow locked to the ski. A clean boot sole facilitates easy locking and" unlocking of the boot in step in bindings. A clean boot sole is essential if the boot is to properly release from the binding under emergency conditions. Despite this important need, little commercial success has been attained with an appropriate boot scraper. Part of the difficulty is that a portable boot scraper, which is manually applied to the boot just prior to placing the boot in a binding is cumbersome and awkward to use and so is unacceptable to the average skier. Connecting a boot scraper to the ski itself has also not been successful for several reasons. On the one hand, an appropriate construction which will not interfere with the performance of the ski is required and this presents major problems to the manufacturer. Sophisticated boot scrapers requiring intricate machining operations during their assembly are too uneconomical to manufacture. Furthermore, the boot scraper must be structured and positioned so that a skier can easily clean one boot while the other boot is in its binding. This requirement also presents a difficult problem since the boot scraper must be effective to receive the sole of the boot from almost any direction. In addition, the entire cleaning operation must be comfortable to the skier and therefore control of the ski must be maintained during the cleaning. Thus far, none of the prior art devices have been successful in solving all of these problems.
BRIEF DESCRIPTION OF THE DRAWING It is the primary object of this invention to provide a boot scraper in combination with a ski which is adapted to receive and clean the lower surface of a ski boot when the boot is moved across the scraper in substantially any direction.
It is another object of this invention to provide control means for use in conjunction with a boot scraper and ski to enable the skier to control the movement of the ski when cleaning a ski boot.
It is still another object of this invention to provide a boot scraper in combination with a ski which is economical to manufacture and assemble.
These and other objects will become apparent from the following description of the invention taken in conjunction with the following drawings, in which:
FIG. 1 is a perspective view of a combination of a ski and boot scraper with a ski pole positioned in the crown section of the boot scraper;
FIG. 2 is a partial top view of the combination of FIG. 1, and specifically of the boot scraper; and
FIG. 3 is a side elevational view of the boot scraper taken on line 33 of FIG. 2 and includes a ski pole and a ski boot in operative position relative to the boot scraper.
DETAILED DESCRIPTION OF THE DRAWING Broadly described the invention comprises in combination with a ski, a boot scraping means which itself comprises a member operatively connected to the upper surface of the ski, and a plurality of rigid parts projecting upwardly from the member. The parts are oriented on the member so as to extend across the member in several directions relative to the longitudinal axis of the ski and are structured to receive and clean the lower surface of a ski boot. With this construction, a ski boot may be scraped against the parts from substantially any direction thus allowing the skier a high degree of mobility while cleaning his boots.
In the preferred form of the invention, the boot scraper comprises an elongated member attached to the upper surface of the ski and extending along the longitudinal axis of the ski. The upwardly projecting parts may be composed of the same material as the member and integrally formed therewith and extend across the member in several of randomly oriented sections but preferably are V-shaped sections extending across the entire width of the member. When a plurality of aligned closely spaced V-sections are positioned on the member the lower surface of a boot is easily brought in contact with any section from any direction and the friction created by passing the boot over the projecting section is sufficient to clean the snow from the boot.
Inorder to assist the skier while the boot cleaning is being carried out, a control means for controlling the movement of the ski during the cleaning operation is also provided. Preferably, the control means comprises a crown piece extending upwardly from the ski and defining a receptacle which is adapted to receive a ski pole in snug engagement with the crown piece. The snug engagement is such as to provide resistance to lateral movement of the ski pole. Movement of the ski is thereby controlled since the crown piece is securely connected to the ski and in the preferred embodiment, it forms a part of the boot scraper itself.
Referring now to the drawing and specifically FIG. 1, there is shown the combination of the invention generally designated by the numberal 10 of a ski l2 and a boot scraping means 14. The ski 12 may be any conventional ski of uniform length and width. As with most skis, the ski 12 is equipped with a boot binding connected to the upper surface 16 and comprising a toereceiving element 18, a heel receiving element 20, a heel encircling spring element 22 and straps 24 and 26 for extension around the ski boot, the straps being secured to the plate 20 by means of ears 28 and 30. It will be understood that the showing of the boot-receiving means is illustrative only and forms no part of this invention. Any boot-receiving means would be satisfactory and the illustration is intended primarily to show the position of the boot scraping means 14.
As illustrated best in FIGS. 1-3, the boot scraping means 14 comprises an elongated member 32 which is secured to the upper surface 16 of ski 12 by means of a suitable bonding material 34 (FIG. 3). Any suitable pressure sensitive adhesive may be used for the bonding material 34 and it may be in the form of a pad cut to size with an exposed adhesive layer on its upper and lower faces similar to the pad illustrated and described in US. Pat. No. 3,284,091. Alternatively, the member 32 may be secured to the ski 12 by means of bolts (not shown) or other typical securing means.
The member 32 includes a plurality of upwardly projecting parts designated by the numeral 36. The parts 36 are rigid and are preferably formed as an integral portion of member 32. These parts 36 receive the lower surface 37 of a boot 38 to dislodge any snow on the underside of the boot. To assist in dislodging the snow, the parts 36 are typically provided with tapered sides 40 which form an easily accessible vertex junction 42 over which the sole 37 of boot 38 may readily be moved in frictional engagement. As illustrated, the parts 36 are positioned crosswise of the member 32 but extend thereacross in several directions relative to the direction of the longitudinal axis of the ski 12 (illustrated by the arrow 44 in FIG. 1). With this construction, the boot 38 may be passed across the junctions 42in any direction and dislodging of the snow will be easily effected.'This enables a skier to readily clean one boot while the other boot is in the binding of the other ski.
A preferred structure of the invention is shown best in FIG. 2. There the parts 36 extend across the entire width of the member 32 which is shown extending across substantially the entire width of ski l2 and each part 36 includes a first section 46 and a second section 48. These sections intersect at a position 50 at about the midpoint of the ski 12. As such, the parts 36 are V- shaped, and'the sections 46 and 48 extend across the member 32 in different directions relative to the direction of the longitudinal axis of the ski. A plurality of such V-shaped parts 36 are aligned and evenly spaced along the length of the ski 12 in sufficient quantity to provide a number of boot scraping surfaces thus permitting the boot scraping means to be used conveniently by the skier.
To assist the skier in controlling the movement of the ski during the boot scraping operation, a control means 52 is provided. The control means 52 is preferably formed as a part of boot scraping means 14 but may be separated therefrom. As shown best in FIGS. 2 and 3, the control means 52 comprises an upwardly projecting crown piece 54 which defines a receptacle 56 adapted to receive the tapered lower section 58 of a ski pole 60 in a snug engagement. The engagement of section 58 in receptacle 56 is one in which substantially no lateral movement of the pole 60 is permitted, thus allowing the skier to control the movement of the ski when scraping his boot by holding the ski firmly in place with the ski pole. With this structure, the skier does not have to bend over during the use of the scraping means and may easily clean one shoe while the other is bound to another ski.
While the dimensions of the boot scraping means may vary, best results are achieved if a large snow removing area is included. Thus, it is highly preferable to extend the member 32 across substantially the entire width of the ski and to elongate the member so that the entire length of the boot can be clean with one action. In one typical example, a width of 2 A inches and a length of 13 inches has been found to be operationally quite successful. An additional 5 inches in length is included for the crown piece 52. The parts 36 project upwardly from the /2 inch thick base portion of the member approximately 3/4 inch while the crown piece rises 3 inches above the base portion. With these dimensions, at least six V-shaped sections may be aligned along the member to provide a large surface area for snow removal.
The member 32 and particularly the projecting parts 36'may be composed of any suitable material which is strong and yet slightly flexible. The flexibility is desirable in order that the boot scraping means may accommodate the flexing of the ski during use conditions. For this purpose, the scraping means is molded from any suitable plastic such as acrylonitrile butadiene styrene. Other suitable comparable materials such as a hard neoprene are also satisfactory.
Although the illustrated and described embodiment of the invention is preferred for best results, many modifications may be made without departing from the scope of the invention. For example, the parts 36 may be randomly positioned on the member 32. In addition, the crown piece 52 may be separately positioned on the 'ski, even at a' different location than the scraping means. The scraping means itself may be located at any convenient location on the ski either before or after the toe and heel binding mechanism. Other departures are also apparent and may readily be made to enhance the operational value of the boot scraper.
From the foregoing, it will be appreciated that the boot scraping means of the invention is economical to manufacture and assemble, easy to use by the skier, provides control of the ski during use, and enables a skier to clean his boot from any direction relative to the scraping means. As such, it provides a highly attractive combination of advantageous characteristics and solves many of the problems still outstanding in this art.
