Definitions

  • a third problem facing the skier is that of determining the best boot buckling pattern.
  • Modern ski boots provide multiple, adjustable buckles to permit the wearer to optimize the boot's support against the different skiing forces.
  • individuals spend a major amount of their actual skiing time trying to find, through trial and error, the optimal setting for each buckle in order to stabilize their feet and ankles, without cutting off circulation. These settings are especially difficult to establish while the boots are still in the breaking-in-period.
  • Another major problem is that of preconditioning the feet, ankle and leg muscles which are used uniquely in skiing. Even with properly fitted ski boots, many muscles in the feet and ankles are called on to contract strongly and frequently so as to stabilize against edging and other weight-shifting forces which are encountered while skiing. When, as is typical at the start of the ski season, the particular muscles have not been used actively for several months or more, they invariably will have lost any previously developed degree of endurance. Accordingly, the muscles will begin to ache and cramp after an initial ski run or two, and directly interfere with the skier's ability to enjoy, or even to continue the skiing.
  • This is achieved by the individuals working against the inherent flex resistances presented by their boots, and/or against selected degrees of their own body weight, effectively to exert and repetitiously practice many of the basic, side-to-side edging, or front-to-back, or up and down weight-transferring and balancing actions all of which are inherent in skiing.
  • the invention provides a convenient and practical means for performing both preparatory tests and exercises, so that individuals may achieve better initial boot selection, boot break-in, boot adjustment proficiency, as well as more specific and effective pre-ski muscle conditioning and the reacquisition of certain basic skiing skills.
  • Another objective of the invention is to provide such an exercise apparatus which is capable of accepting various common sizes of skis, or simulated skis; which can be quickly set up or dismantled; and which, when dismantled, can be conveniently packaged and hand carried.
  • Another objective of the invention is to provide such apparatus which is inexpensive to produce, and which can be sold at a relatively low price.
  • the invention provides an apparatus for pre-ski testing and exercising by a person wearing ski boots, the apparatus including first means for fixing said ski boots in a spaced and parallel relationship to one another, such that they cannot be moved freely independently of one another in either a vertical or horizontal plane; and second means for allowing the person forcibly to rock said first means from side-to-side, and rock said first means forwards and backwards, and to lift said first means up and down against the corresponding flex resistances of the boots and against the body weight of the person.
  • two simulated skis 10 are clamped in spaced and parallel relationship to two transverse bars or tubular members 14.
  • the simulated skis may take the form of elongated aluminum channels of the illustrated configuration.
  • the bars 14 respectively extend across the simulated skis 10 just in front of and just behind the bindings which are designated 12.
  • Each of the bars 14 is supported on first and second triangular-shaped rocker blocks 16 respectively positioned near its ends.
  • Each bar may be supported by rocker blocks 16 at a selected height above the supporting surface, by inserting it in one of a number of holes 17 in each rocker block 16.
  • the rear bar 14 is supported in the central holes in its rocker blocks, and the forward bar is supported in lower holes, so that the simulated skis 10 are tilted slightly in the forward direction.
  • the bars 14 are held in the corresponding rocker blocks 16 by appropriate sleeves, such as sleeves 18.
  • the simulated skis 10 of FIGURES 1 and 2 are held on bars 14 by clamping plates 20a shown in FIGURE 3.
  • Each clamping plate 20a is adapted to be received under the corresponding simulated ski, and a U-shaped adjustable clamp 20d is provided for attaching the plate 20a to the corresponding bar 14.
  • a total of four clamping plates 20a are used to attach the simulated skis 10 to the two transverse bars 14.
  • One of the clamping plates 20a is shown inverted in FIGURE 3 to reveal clamp 20d.
  • the clamp is attached to plate 20a by two screws, one of the screws being provided with a wing nut 20b which is manually turned to tighten the plate 20a down on the flange of the simulated ski 10, and to tighten the flange against bar 14.
  • FIGURE 4 A different type of clamping assembly is shown in FIGURE 4 which is designated 22.
  • This latter clamping assembly may be used to clamp either actual skis, or the simulated skis of FIGURES 1 and 2 to the transverse bars 12.
  • FIGURE 5 shows a pair of actual skis 24 attached to the apparatus of FIGURE 4 by means of the clamping assemblies 22.
  • FIGURES 1-5 essentially prevents the skis, or simulated skis, from rotating about their longitudinal axes, or from moving freely independently of one another, in either a vertical or horizontal plane, while at the same time, permitting users to stand on the skis, or simulated skis, with their ski boots secured to bindings, and with their weight shifted slightly forward onto the balls of their feet, similar to the prevailing conditions for downhill skiing. Then, by working variously against the flex resistance of the boots, and/or against their own body weight, the users can simulate various skiing actions, and can experience corresponding and representative skiing forces upon their feet, ankles and legs.
  • the various maneuvers that can be caried out by the users include, for example, (1) forceably to angulate their feet and legs, and to shift their body weight from side-to-side, as in edging, against the corresponding side-flex resistance of their boots. As test, this action reveals any free play that might be present in this plane in the boots. As an exercise, this action works the many lateral stabilizing muscles in the feet, ankles and legs. (2) To rock forward and backward against the corresponding flex resistance of the boots, as well as the individual's partial body weight, to test for any free boot/ankle movement permitted by the boots in this plane, and/or to exercise the various anterior and posterior flexor muscles of the feet, ankles and legs. (3) Alternately to lift one leg and then the other against the resistance created by the individual's partial body weight, transmitted through the non-lifted leg to the clamping/supported devices, so as to exercise the leg-lifting muscles in the legs, pelvis and trunk.
  • a user may perform a one-side weight balance and opposite-side lift action, similar to skiing through bumps.
  • the cross bars of the clamping devices rock and pivot around the attached rocker blocks.
  • This exercise strongly works leg lifting and trunk side flexion muscles, with the degree of resistance encountered being determined by the distance the rocker blocks are spaced from the bindings of the skis, or simulated skis.
  • the subject may perform a forward lean exercise, thereby strongly contracting plantar flexion muscles of the ankles, plus corresponding stabilizing muscles in the feet.
  • the rear clamping device and corresponding rocker blocks are pulled off the ground, with the degree of resistance encountered being determined by the forward flex resistance of the ski boots and the distance the front cross bar is positioned in front of the ski boots.
  • the resistance encountered while performing a backward rocking-front lifting'exercise may also be varied.
  • the position of the cross bars is readily adjustable, by loosening the clamping devices of FIGURES 3 or 4, and sliding the assemblies shown in FIGURES 3 or 4 either forwardly or rearwardly with respect to the supported skis, or simulated skis, and by then tightening the clamping assemblies.
  • FIGURE 8 the subject is shown performing a quad-dip exercise, with the arms fully forward as in a race start position. This exercise works the quadriceps (knee extensor) muscles in substantially the same way as in skiing.
  • a number of other exercises may also be performed by the apparatus of the invention, as will become readily apparent to anyone having basic skiing experience, using the apparatus. Accordingly, while the foregoing examples are illustrative of some of the basic types of skiing tests and/or exercises which may be performed by use of the apparatus of the invention, many other tests and/or exercise movement-variations may be readily performed, to exercise different muscle groups in different ways, and to allow individuals to select pre-ski tests and exercises so as to suit their own particular needs and objectives.
  • FIGURE 9 is a top view of one of the bindings mounted on one of the simulted skis 10
  • FIGURE 10 is a side view
  • FIGURES 11-13 are end and sectional views taken along the lines 11-11, 12-12, and 13-13 of FIGURE 10.
  • the binding 12 includes a forward bracket 12A which is intended to receive the toe of the ski boot. Bracket"12A may be moved back and forth along simulates ski 10, and may be clamped at any selected position on the ski by tightening a set screw 12B against the top of the simulated ski, as shown in FIGURE 11.
  • the binding 12 also includes a rear bracket 12C for supporting the heel of the ski boot. Bracket 12C may likewise be moved back and forth along the simulated ski 10 when in its released position.
  • the usual procedure is to locate the bracket 12A at a desired position on the simulated ski, and clamp that bracket in place. Then, the toe of the ski boot is brought adjacent to the rear end of the bracket 12A to protrude under the rear end.
  • the rear bracket 12C is then moved along the ski until it contacts the heel of the ski boot, at which time a lever bar 12D is pulled upwardly to turn a pair of levers 12E about pins 12F, so as to bring a cross bar 12G down against the upper surface of the simulated ski 10 with levers 12E in an upright position.
  • a resilient bushing 12M is provided on bar 12G which engages the top of the simulated ski 10 when the rear bracket 12c is in its clamping position.
  • a bracket 12J For that position of the lever arms, the forward edge of a bracket 12J is brought down over the upper edge of the heel of the ski boot with a pair of pins 12H being held firmly against the rim of the simulated ski 10, as shown in FIGURE 13. This enables that the bracket 12J to be firmly clamped down against the edge of the heel of the ski boot, holding the ski boot firmly in place.
  • levers 12D When levers 12D are in their upright clamping position, one of the levers 12D engages a limit stop 12K.
  • the rear bracket 16 may be released merely by pulling back bar 12 D , to turn the lever arms 12E in a counterclockwise direction in FIGURE 10, which releases the bracket.
  • a further bar 12L is provided which extends across the top of the simulated ski 10, and which holds the bracket in position when it is in its released condition, to enable the bracket easily to be moved back and forth along the ski 10.
