Definitions

  • a ski boot having a shell comprising two complementary parts whioh are assembled together and include a means whereby a skier can vary the flexure of the ski boot.
  • ski boots presently available comprise a substantially rigid outer shell generally made of a plastic material.
  • a liner member is normally disposed within the shell and serves as a cushion between the shell and the foot of a skier. When a skier is in a forward lean position at which time the knees of the skier generally are instance, the skis act as an extension of the skiers feet.
  • skiers with less experience do not desire ski boots without flex as this affects the comfort of the skier.
  • these skiers are desirous of having some means of controlling the responsiveness of the skis.
  • ski boots do not have a means for readily adjusting the flex in a boot. Rather, because of the relatively stiff plastic materials utilized in ski boot shells, the shell of the boot is substantially rigid.
  • the sole means for providing any flexure in the boot are the adjustments provided with the buckle closure system of a particular boot. In this respect the buckle closure systems do not serve to satisfy entirely the flexure requirements for various skiers. Accordingly, it is desired to provide some other means of providing the desired flexure in the shell of a ski boot. Additionally, it is desired to accomplish the provision of an adjustable flexure means while at the same time providing a boot which affords relative ease of manufacture and assembly.
  • mentary shell portions which, upon assembly of the shell, are joined together-by suitable fastening means such as screws.
  • the two portions which form the vamp of the shell are complementary parts that are joined togcther at their respective parting lines.
  • the parting lines of the shell portions lie substantially in a vertical plane that transverses a center line which extends from the front or toe to the rear of the boot.
  • the outer shell is completed by a rear tongue assembly which is adapted to be connected to the assembled shell portions.
  • An adjustable clamping means is adapted to slide along a flanged track located on the front of the assembled shell.
  • the clamping means can be positioned in any one of a number of positions at which position the clamping means is securely fastened with the corresponding effect that the shell will permit only a certain amount of flexure when the boot is in use.
  • the boot of the present invention is adapted to be provided with a suitable liner and wax fitting system such as the liner and fitting system of the type described in our pending application. Ser. No. 216.080 filed Jan. 7, 1972. Moreover the present boot is 7 adapted to be provided with interchangeable backs of the type described in our pending application Ser. No. 231,967 filed Mar. 6, 1972. It isappreciated, however, that other liners could be employed with the boot of the present invention and that other boots aside from the rear entry type disclosed herein could utilize the new and unobvious invention disclosed and claimed herein.
  • FIG. 1 shows a side view of the ski boot of the present invention with the rear portion of the boot cut away to expose the bottom ribbed section of one shell portion:
  • FIG. 2 shows a tongue with an attaching tab. the tongue, upon assembly, being disposed between the inner wall of the shell and the outer wall of the liner as shown in FIGS. 1 and 3;
  • FIG. 3 shows an enlarged section of the shell portions of the ski boot of the present invention with the shell portions forced opened in an operative skiing position whereby portions of the flanged ribs on the shell portion are forced outwardly from each other so that the boot can flex the desired amount;
  • FIG. 4 shows an enlarged section taken along lines 44 of FIG. 1.
  • FIG. 1 there is shown a ski boot 10 which includes stiff sole 12 having front section 14 and rear section 16 adapted to engage ski bindings.
  • the shell 5 of the boot is preferably molded in two complementary shell portions l7, 18 which are mated together in a vertical plane 9 which passes through a center line which extends from the front or toe to the rear of the boot.
  • Shell portions l7, 18 are fastened together along the length of the sole by suitable fastening means such as screws 8 which are inserted into recessed holes 7 in portion I8 and screwed into holes 6 located in portion 17.
  • Each shell portion is preferably molded so that sole 12 is integral and that floor 22 of the shell. upon assembly of the boot, serves to support inner liner 24. Liner 24 is disposed within shell 5 and is located between the assembled shell and the foot of a skier.
  • Sole 12 is connected to floor 22 by means of spaced ribs 25. Air spaces 26 are located between spaced ribs and serve to reduce the weight of the boot by eliminat'ing material from the sole of the boot.
  • the ribs are of sufficient strength to withstand the weight of the skier and the forces that will act upon the boot when the boot is worn. If it is desired to vary the weight of the boot for a particular skier on application, these spaces could befllled with material to achieve the desired boot weight.
  • shell portion 18 has tabs 27 located at the front and rear of the shell portion. These tabs, upon assembly, are inserted in corresponding grooves 28 located at the front and rear of shell portion 17.
  • a groove 29a is also located along a substantial portion of the length of portion 17.
  • a corresponding tab 29, adapted to fit in groove 29a, is located along a substantial portion of portion 18 and is adapted
  • the front of portions 17 and 18 serve, when the portions are joined, to form the vamp of the boot.
  • Each portion has a rib 30, 31 extending outwardly from the rounded contoured section of the shell portion. Rib has a flange 32 and rib 31 has flange 33.
  • the flanges project outwardly from each other and are substantially perpendicular to the ribs.
  • Slide clip 34 is positioned to slide along at least a portion of track 35 which is composed of flanged ribs 30, 31. That portion of track 35 which is located nearest the toe area of the boot, utilizes rivets 36 or other suitable fastening means to securely fasten ribs 30, 31.
  • a number of holes 37 are located at selected positions along the length of the track which is unriv- Legs 61, 62 each have an inwardly extending flange 63 at their outboard end.
  • Leg 61 is threaded to receive fastening screw 38 whereas the leg 62 has a hole 64 which is at least slightly larger in diameter than the head diameter of screw 38. Hole 64 is aligned with the threaded hole in leg 61.
  • the desired flex properties in the boot can be achieved by positioning clip 34 at a particular hole location 37.
  • screw 38 When a skier desires to change the flex in the ski boot, screw 38 is unscrewed and removed from hole 37. Clip 34 is then moved along track 35 to one of the other holes 37. Screw 38 is then reinserted in the hole and threaded into threaded hole in Ieg61 until the head of the screw is disposed within the hole 64 of leg 62. It will be appreciated that when clip 34 is positioned near the top portion of track 35, the least amount of flexure will be permitted whereas the flexure in the boot will increase as clip 34 is moved along track 35 toward the toe of the boot.
  • shell portions 17, 18 are adapted to separate at the location of ribs 30, 31 along the length of the track 35 to the point where the ribs are fastened securely together by clip 34.
  • clip 34 is slide clip 34 downward along track 35 to a particular adjusting hole 37 where the screw 38 is threaded in position to securely fasten the clip in position.
  • Tongue 40 is disposed between the outer wall of liner 24 and the inner wall of shell 5 to preclude snow from contacting the liner 24 upon separation of ribs 30, 31. Tongue 40 is preferably molded and can be made of the same or different materials than the shell material. Tab 41 is integral with and projects outwardly from the bottom of tongue 40, tab 41 being contiguous to the bottom edge 43 of the tongue. The tongue is contoured to follow substantially the contour of the shell and liner at the area where the tongue is inserted in the boot.
  • tongue 40 is located behind ribs 30, 31 and in front of liner 24, which includes a foam liner and wax filled bladder.
  • the tongue extends along a portion of the length of track 35 and projects slightly beyond the top of the shell at 44.
  • Ribs 30 and 31 are each recessed at for at least one half the thickness of tab 41 and are formed to the shape of the tab. Upon assembly of shell portions 17, 18, tab 41 is positioned in recesses 50in ribs 30, 31 and hole 49 is aligned with rivet hole 36 in each shell portion after which a rivet or other fastening means secures the tab and shell portions together.
  • tongue 40 serves to keep snow from entering between the shell and liner 24 at the area exposed by the opened ribs. Moreover the shell portions, upon flexure of the boot. will not rub against the liner at the location of ribs 30, 31, but rather will contact the front surface 51 of tongue 40.
  • the boot of the present invention provides a means for adjusting the flex in the boot to that desired by a skier.
  • the shell of the boot is split for a portion commencing from the top of the boot and extending toward the bottom of the boot.
  • Means such as clip 34 are provided for connecting the split shell at any of a number of selected positions along the length of the split portion so that when pressure is exerted on the shell. the shell will separate along the length of the split to the location where the connecting means securely fastens the split portions together.
