SKI

Filed Nov. 29, 1959 Patented Apr. 8, 1941 SKI Willi Ncuhauser, St. Gall, Switzerland Application November 29, 1939, Serial No. 306,734 In Switzerland December 1'7, 1938 5 Claimsr (01. 280-1135) The skier when moving strives to maintain his body in a position that is inclined from the vertical rearwardly rather than forwardly, but he advantageously would sooner maintain his body inclined forwardly which the experts consider to be required. To assist in this, ski boots fitted with a wedge have come into use in order to set the foot at an angle forwardly inclined with respect to the ski. This device is useful while moving forward, but on the other hand it induces tiredness very rapidly even without skis on the march or when climbing, as the foot is held in a sloping position to which men. particularly are unaccustomed.

The same objection would arise by the use of a covering on the boot firmly secured to the ski, which covering would force the foot to take up a permanently sloping position. This disadvantage is avoided according to the present invention according to which a movable intermediate block or layer is placed between the heel of the boot and the ski for the purpose of giving to the foot a position inclined forwardly with respect to the ski only when the need arises. The intermediate block or layer may for example be so providedthat it is secured to the ski as a sliding member and can be fixed beneath and to the rear of the heel, whereby the change can be made at any time instantaneously and without loosening the ski from the foot.

The accompanying drawing illustrates by way of example one construction of the device according to the invention.

Figure 1 shows a ski of known construction having a boot buckled to it.

Figure 2 is a ski with a buckled-n boot provided with an intermediate block or layer.

Figure 3 is a ski with a buckled-on boot showing the intermediate block or layer retracted.

Figures 4 and 5 show details.

Referring to the drawing the boot 2 is secured by means of a known fastening to the ski I (Figure l). The dotted line 3 shows how in the boot a sloping position for the foot is produced by means of a Wedge.

Figure 2 shows the same ski and an ordinary ski boot with an intermediate block or layer 4 between the heel of the boot and the ski.

Figure 3 shows the boot in normal position. The intermediate block or layer 4 is located to the rear of the heel.

Figures 4 and 5 show by way of example one construction of the intermediate block or layer.

A plate 5 is securely screwed to the ski 'l. The lateral recesses B at the underside of the plate 5 serve as guides for the intermediate block or layer 4, enabling the latter to make a longitudinal movement on the plate 5. Secured to the intermediate block or layer 4 is a. spring I, which is provided with one pin 3, that corresponds to the holes III or II in the plate 5. The pin 8 is employed for determining the position of the intermediate block or layer 4 in both locations. The projecting stop l2 in the form of a screw prevents the intermediate block or layer 4 from being lost. In order that the intermediate block or layer 4 shall not substantially add to the weight of the ski, it is advantageously made hollow and of alight metal. The intermediate block or layer between the heel and the ski increases the distance between them, so that the spring I3 of the fastening becomes operative at a more favourable angle. Women accustomed to high heels will when wearing the skis use the intermediate block or layer on the march and when climbing, as this position of the foot is more comfortable to them.

Many forms of the device are possible Without departing from the invention.

I claim:

1. In a ski having a heel supporting zone on its upper surface, a substantially wedge-shaped block carried on the upper surface of said ski, and a guideway on said ski, said block being slidable on said guideway from an inoperative position rearwardly of said heel supporting zone to an operative heel supporting position in said zone.-

2. In a ski having a heel supporting zone on its upper surface, a substantially wedge-shaped block carried on the upper surface of said ski, a guideway on said ski, said block being slidable on said guideway from an inoperative position rearwardly of said heel supporting zone to an operative heel supporting position in said zone, and means for releasably locking said block in both positions.

3. In a ski having a heel supporting zone on its upper surface, a substantially wedge-shaped block carried on the upper surface of said ski, a. plate fixed on the upper surface of said ski, longitudinally extending guide grooves formed in the side edges of said plate, and means on said block engaging said grooves to guide said block sliding movement from an inoperative position rearwardly of said zone to an heel supporting position in said zone.

4. The structure of claim 3, longitudinally spaced apertures in said plate, a spring pin carried by said block and adapted to be selectively extending guideway, means slidably connecting said block to said guideway for sliding movement from an inoperative position rearwardly of said heel supporting zone to an operative heel supporting position in said zone.
