Definitions

  • the present invention relates to a ski binding for connecting the skis with the boot.
  • This tension connection comprises a rotatable pressure spring which is fixed between the holder, according to one embodiment of the present invention being a rocker, and the bent-lever pivoted at the bearing block of the ski; the rotatable pressure spring becomes a flexible tension member when the binding is released.
  • FIGURE 1 is a side elevation of a first embodiment of the ski binding
  • FIG. 2 is a top plan view thereof
  • FIG. 3 is a section along the. lines 3--3 of FIG. 4;
  • FIG. 4 is a fragmentary longitudinal section of the rear portion of the ski binding.
  • FIG. 5 is a side elevation of the first embodiment of FIG. 1 including an additional device.
  • a rocker 1 is used for a holder which disengage at the occurrence of an overstrain.
  • the rocker 1 turns about the balls 2 which form abutments biased by springs 3 and which engage the seats 4 of the rocker 1.
  • the rocker 1 On the shaft 5 the rocker 1 carries the rollers 6 and 7 which grip over the rear edge of the boot.
  • the rollers 6 and 7 can be adjusted as to their height by the rocker 1 which is formed as a two-part adjustable angular member.
  • the fork part 8 of the angular member can be adjusted and Patented June 1, 1965 "ice locked by means of screws 9 and a star-shaped boss 11 pressed in on the friction surfaces 10.
  • the rollers 6 and 7 press down the heel of the boot and at the same time push the boot against the front swivel jaw 13 which is pivoted on the threaded pin 14 and constitutes the holding down device.
  • the balls 2 are embedded in threaded sleeves 15 of the base plate 16 which is screwed to the ski 17.
  • a bentlever 19 is pivoted to a bearing block 18 of the base plate 16, to which lever 19 a spring abutment'20 is hinged.
  • a screw cap 21, to which a pressure spring 22 is clamped, is screwed into the abutment 20.
  • the pressure spring 22 abuts a ball portion of hemispherical shape 23 and biases the ball portion 23 against the seat 24 of the rocker 1. If the spring 22- is rotated with the screw cap 21 its length is varied; thereby the pressure exerted on the boot by the bent-lever 19 through the pressure spring 22, the rocker 1 and the rollers 6 and 7 is likewise varied.
  • a lateral movement of the spring 22 perpendicularly to its longitudinal axis is prevented by a guiding pin 25, which is'universally coupled to thescrew cap 21, passes through the ball portion of hemispherical shape 23 and is secured to the rocker 1 by means of'a washer 26 and a pin 27.
  • the rocker 1 If overloaded, either by tension or by torsion, the rocker 1 either is drawn out upwardly, the balls 2 giving away or it is turned around the axis 33 due to the component force acting on the rollers 6 and 7', thereby, the rocker 1 springs out also of the balls 2 and releases the boot.
  • an ankle catch strap 32 In a slot 28 of the fork 8 is suspended an ankle catch strap 32.
  • the strap 32 connects the boot with the rocker 1, which in turn is connected With the ski 17 by means of the spring 22 and the guiding pin 25.
  • Pre-stressing of the springs 3 is effected by means of screw caps 29; the latter have index marks 30 which permit a predetermined maximum adjustment.
  • the rocker 1 can be taken off the spring abutment 20 by completely unscrewing the spring 22.
  • stop studs 31 are arranged which prevent an unintentional lateral swinging of the front swivel jaw 13'.
  • the cones 12 center the boot in the swivel jaw 13.
  • the rocker 1 as described above is taken ofif and a long-run-strap (not shown) is hooked into the stop studs 31 and is put under stress around the edge of the heel by means of a heel tightener or heel clamp.
  • the sliding rest 70, 71 and 72 which can be inserted, renders a lateral guidance.
  • the catch strap 32 is bent in the form of an S and two loops 34 are put around the layers 33, the loops 34 compressi'ngthe layers 33. If the boot, as described, disengages itself from the ski in case of a sudden fall, the layers 33 contract and the catch strap 32 elongates like the rope of -a tackle, the loops 34 approaching each other. By pulling on the rollers 36 of the loops 34 the ankle catch strap 32 can be shortened again after the fall.
  • the layers 33 provide a' restraining friction brake, when thecatch strap 32 is drawn out; thus they prevent the strap 32 from being ruptured, as wellv as the trailing ski fiom hitting.
  • V i f A swivel plate 35 is arranged beneath the sole of the boot; the fulcrum of the plate 35 is underthe ball of the foot and the' plate 35 is directed backwards; the plate 35 facilitates the heel to be turned out of the binding in case of a fall.
  • FIG. 5 of the drawings a simple additional device is shown by means of which the binding, according to the first embodiment, can be modified for touring.
  • Two pins 566 are fed into two tubular rivets 565 which are inserted in the heel from below.
  • the pins 566 are parts of a slide bar 567, which is additionally secured at its top to the boot by means of straps 568.
  • the rollers ledge 569' of theslide bar 567 preventsithe'rollers 506 and 507 from disengaging fromthe'bar.
  • A, ski binding comprising a holder adapted to grip a ski boot, means for securing said holderto a'ski, said securing means. including spring-biased supports yieldable turnably about the front portion of the ski boot in response to an adjustable overstrain in the upward direction of the heel of-the boot and in both lateral directions thereof, said'holder comprising a rocker, base plate means adapted to be secured to'a ski, spring biased pressure balls cooperatively associated with said base plate means for releasably securing said rocker to said base plate means by abutment with said rocker, so thatsaid'rocker disengages from said base plate means ata vertical as well as at a horizontal overstrain, and
  • an adjustable pressure spring disposed longitudinally.
  • the ski binding as set forth in claim 1, which includes a plurality of rollers, one of said rollers being disposed at the center and being double conic and two of, said rollers being conic tapering toward said center roller, said rollers being rotatably mounted at the front end of said rocker and adapted to grip over the rear heel edge, and said center roller, pressing itself into-the boot leather.
  • ski binding as set forth in claim 1, which includes a bent-lever, a bearing block securing saidbent-lever to theski, and said bent-lever having a spring abutment for tightening said rocker againsttheboot by means of said adjustable pressure spring.
  • a 4 The ski binding, as set forth in claim. 3, which includes I a guiding pin resting in said pressure spring,
  • ski binding as set forth in claim 3, which'iucludes a screw cap
  • said screw caps have engraved indication marks to set said screw-caps in accordance with predetermined pressure of said pressure balls.
  • a ski binding comprising a holder adapted to grip a ski boot
  • said securing means including spring-biased supports which are yieldable turnably about the front portion of the ski boot in response to an adjustable overstrain inthe upward direction of the heel of the ski boot and in both lateral directions thereof.
  • said holder comprising rocker means
  • the ski binding as set forth in claim 8, which includes an arch rail adapted to be strapped on behind the heel, said arch rail engaging in cylindrical recesses under the heel by means of two tapered pins and adapted to be strapped at its top by straps to the ankle, said holder comprising arear tightener having pressing rollers,
  • said arch rail having a profile for frictionless movement of the pressing rollers of said rear tightener
  • said arch rail carrying at its lower enda transversal ledge in order to prevent the rollers from riding off completely from said arch rail.
