Description
133~33 Thls inventlon relates to a skl and, more particularly, to a ski whlch may ~e used ln a variety of snow condltlons and, more partlcularly, soft snow.
Skiing has become an extremely popular sport for people of all ages. A vast majorlty of the SKilng and particularly downhill skilng is performed on skl areas in whlch the snow conditions are controlled by means of packlng and grooming equipment. As a result, skl manufacturers deslgn and cons-truct skls whlch are optimized to accommodate skiing on these groomed hllls.
There are, however, SKier3 who would prefer to ski on ungroomed and unpacked hllls or in the country where trails have not been set. Conventlonal downhill and cross country ski~ are not well suited to these soft snow conditions as they tend to slnk in and there~y drastlcally reduce maneuver-ablllty .
The present lnventlon provldes a ski which has the -~
characterlstic of facllitatlng maneuvers in the sport of skilng lncluding the turns of skiing downhill, and the ~tepplng movements required when walking on the flat and the stepplng movements requlred when climbing uphill. The ski of the present lnvention is designed to remain close to the surface of the soft snow such that it wlll float, plane or allow foot steering. The tip of the ski will remain out of the soft snow when either wal~ing on the flat or when; -climblng uphill or when skilng downhill. The ski of the present design facllitates turning and stepplng movements by decreaslng the ski length, increasing the ski width and by varying the locatlon of the skier's center of gravity. The theory behind the invention is that in soft snow, in order to be maneuverable, a ski must be short. Yet it stlll must stay near the surface wlth the ski tips out of the snow. It, therefore, must not only be short but must also have a large area for floatatlon, and a center of gravity which is adjustable slightly bacK of a constantly changing medlum . ~: .

j1 ~:
l332~3 polnt. This concept is, oL course, belng popularlzed in the sport of wlnd surfing wherein planing and foot steering is used.
There lS dlsclosed ln the prior art very short skis but they tend to be so short as to slnk so deeply into soft snow as to make climbing lmpossible. The prior art does not dlsclose the necesslty of increaslng the ski width while decreasing the ski length ln order to improve maneuverability and maintain surface area for floatation. The prior art also does not mentio~ the necessity of balance, or the center of gravity in order to keep the SKi tip out of the snow at all tlmes. The prior art does disclose devices which propose to move the skier's center of gravity in an antero posterior dlrection but none of these relate to the aforementioned concept of flotation, planing or foot steering. Most previous devices which teach such adjustment relate primarily to different boot slzes for rental shops. It is also noted that the previous devices of this type are much too heavy to be considered for back country hiking type skiing in un-tracked snow Previous devices are also bulky and they raisethe ski boot a conslderable distance above the ski surface thereby detracting from the ski performance. The prior art relating to adjustment contemplates a smaller range of adjustment, i.e. in the range of three inches compared to the present invention in which the tip of the boot may be moved from one inch forward of the ski midline to flve inches back ' of the midllne for a total range of up to six inches. This requlrement of an increased range of adjustment also means the most serious drawback of all previous devices is that they fall to take lnto account the flexing of the ski when a larger range of adjustment is required. Previous devices, therefore, all make the ski much too stiff or alternatively the fixation screws pull out. Also these devices are much too heavy for skl tourlng whereas the ski of the present device utilizes the metal top of the SKi ltself as the ~3 ':
slidlng rall ln order to make the devlce llghter, to locate the boot flat on the ski and to make the devlce neater and more cosmetlcally acceptable. ~nother aspect of the present invention as compared to the prior art is that the adjustment is accomplished extremely rapidly and reliably with no tendency to freeze up.
Therefore, the pre~ent invention seeks to provide a soft snow s~i whlch satisfies a long standing need for a multi purpose (tourlng) Skl whlch can be used for cross country skllng and yet will stlll allow the enjoyment of skiing downhill without resorting to the unnatural, uncomfortable and dangerous maneuvers referred to as telemarking.
Therefore, ln accordance with a first aspect of the present invention, there is provided a snow ski for use in a range of snow conditions, the ski having a length in the range of 120 to 180 cms, and a width in the range of 7 cms to 15 cms, the length and width being selected as a functlon of the weight of a skier using the ski such that the surface area of the ski is approximately 11.2 cms per pound of the -20 skier's weight. :
Accordlng to a second aspect of the inventlon, there is provlded a binding plate for a snow ski, the binding plate having attachment means to receive a ski boot binding and means to attach the binding plate to a ski such that the ;
plate is longitudinally adjustable therealong and locking means to af f lx the plate to the ski.
In accordance with a third aspect, there is provided a snow s~i or use in a range of snow conditions, the ski having a length and width selected as a function of the weight of a skier using the ski following the formula L x W = 11.2 + 1.1 Wt wherein L = length of ski in cms W = width of ski in cms Wt = welght of skier in pounds; and, 13324~3 a ~indlng plate adapted to recelve a ski boot binding, the blnding plate having means to attach the plate to a ski so -that the plate lS adjustable longitudinally of the ski and locklng means to aff lX the plate to the ski.
The invention will now be described in greater detail Wl th reference to the attached drawings wherein:
Figure 1 is a graph of the length verses width of a ski for a 160 pound skier;
Figure 2 shows an acceptable range of length verses width of the ski for skiers of different weights;
Figure 3 shows optimum ski length and width for skiers of differing weights;
Figure 4 is a perspective view of the binding plate of the present invention;
Figure 5 is a top view of the binding plate attached to a ski;
Figure 6 is a side view of the binding plate of Figure 5;
Figure 7 is an end view of the plate of Figure 5;
Figure 8 shows an embodiment to prevent delamination;
Figure 9 is a top view of an alternative embodiment of the binding plate;
Figure 10 is a side view of the plate shown in Figure 9; -Figure 11 is an end view of the binding plate of Figure 9; and, Figure 12 is an end view of an alternate attachment.
Referring to Figure 1, there is shown a graph of the width verses length of a ski for a skier of 160 pounds. It will be noted that the relationship indicated by the graph shows a surface area of 11.2 cms2 per pound of the skier's weight. Included on the graph are other factors which are effected by the length and width relationship. These factors are weight conservation, floatation, stability and maneuver-ability.
The composite graph of Figure 2 shows the acceptable ' ' 1332~33 range of length to width as a function of the weight of the skler. The area with ~he cross hatching indlcates -the acceptable range and the solld llne indlcates the optimum conditions. ~ ~
Figure 3 lS a composlte graph showing optlmum ski length ~ -and wldth for skiers within the weight range of 80 to 200 pounds. For opti-num results, ski length and width should not vary more than 10% (more or less) from the values indicated in the graph.
As previously indicated, the planing or floatation principle is dependent on the aforementioned relatlonship between length and width of the ski. The positioning of the skier's weight with respect to the length of the ski is also of lmportance. For example, if the skier's weight is centered too far to the rearj the heel of the ski will sink `~ ;
too far into the soft snow whereas if the skier's weight is too far forward, the front end or tip of the ski will sink making skiing impossible. Accordingly, in association with optimizing the surface area of the ski, the present invention 20 includes means to adjust the ski boot longitudinally on the -ski. The adjustment is sufficiently simple that it can be performed by the skier in order to accommodate the snow conditions of the area being skied. ~-;
Figure 4 is a perspective view or the preferred embodi- -ment of the binding plate of the present invention. The binding plate shown generally at 10 comprises a forward and rearward, laterally extending member 12 and integrally formed center member 14. The outer end 16 of each cross member 12 is bent around the edge of the ski 20 so as to enter groove 3d 22 formed in the edge 24 of ski 20O Groove 22 is formed by grouting or other means whlch will produce a channel along either side of the ski. Upper metal face 26 of the ski provides a rall 28 for each bent portion 16 to slide along.
Center member 14 o~ binding plate 10 has a longitudinal slot ;
30 through which locking means generally shown at 32 passes '.
1332~3 through. Openlngs 34 in the binding plate provides a means for attaching a normal ski binding as best shown in Figures 6 and 7. Flat head screws 36 go through the upper plate 26 to provide extra s~pport for the upper metal surface of the ski and to prevent delamlnation. Slot 38 is cut in the upper metal surface 26 to permlt removal of blnding plate lO from skl 20. The plate is moved longitudinally of the ski until rear edge 16 of the binding plate is in alignment with slot 38 permitting the binding plate to be removed from the ski.
The portion of the ski immediately beneath channel 30 is provided with regularly spaced openings 40 as best seen in Figures 5 and 6. Locking means 32 as shown in Figures 5 and 6 comprises a hexagonal headed screw having a threaded portion 35 which mates with a helicoil in opening 40. By loosening locking means 32, binding plate 12 is free to slide lengthwise of the ski and may be tightened in a new position such that the binding plate and ski bindings attached thereto are located in the optimum position along the length of the ski depending on the snow conditions. Slot 30 may have in a preferred embodiment countersunk holes 37 which allow hex 33 to be seated therein so as to secure the plate in the correct position. The binding shown in cross hatch in Figures 6 and 7 may be conventional downhill ski bindings or cross country ski bindings.
The binding plate illustrated in Figure 8 is a variation on the embodiment shown in Figure 7. This embodiment has curved portion 16 and slot 22 routed in the side of the ski.
The embodiment of Flgure 8, however, is for use in cases in which delamination is a problem. In this case, normal upper 1: 1 .
metal plate 26 is covered with plastic sheet 50 which is positioned between the metal plate and the binding plate.
; Additional screws 52 provide additional strength to the structure.
In some cases, the ski will not have an upper metal plate 26. The embodiments shown in Figures 9, lO and ll is 1332433 :
deslgned to accomlnodate thls type of ski. In this embodi-ment, bindlng plate 72 is seen to be of a similar shape to binding plate 12 shown in the previous embodiment. In this :
case, however, the outer edges of the plate do not curl around the side of the ski inas,nuch as the upper surface of the ski does not provide a rail which will keep the binding - ~
plate ln position. In this embodiment, angle members 74 are r attached to the side of the ski by attachment means 76 which in a preferred embodiment will be threaded screws. The upper -edge of angle 7~ is bent inwardly to lie parallel to the upper face of the ski and spaced therefrom. The binding -~
plate 72 terminates close to the edge of the ski but extends into the gap created by lip 78. Thus, the binding plate is free to slide longitudinally of the ski and is prevented from twisting sideways by the angle plate 74. Locking means similar to that previously described with reference to Figure 4 is located in a slot along member 79 of binding plate 72.
Figure 11 is an end view of the ski showing the binding plate under angle iron 78.
Figure 12 is an illustration of an alternate embodiment for attachment means 32 previously described. In thls instance, drill hole 40 has a threaded insert glued into the hole so as to retain threaded portion 35 of locking means 33 within the hole.
While there has been shown and described a preEerred embodiment of the invention, it will be appreciated that various modificatlons and adaptations of the invention will become readily apparent to those skilled in the art and it is intended that such obvious modifications and adaptationslbe encompassed within the claims appended hereto.
