Definitions

  • This invention relates to ski boot fastening means, primarily for ski boots having hinged doors.
  • Prior art Rigid shell ski boots such as those shown in U.S. Pats. Nos. 3,313,046 and 3,405,463 have been found to be extremely useful, practical, and give extremely good skiing results.
  • the boot must be made to withstand very severe loads on the foot, particularly in professional skiing where the forces exerted by the skier become very large.
  • the door In utilizing a two cable closure means for the ski boots, it has been found where the door extends toward the forward part of the foot there can be some slight springing of the door. The springing may permit the foot to move slightly which reduces the control that is obtainable with the ski boots when the door is tightly closed, and also the springing may cause leakage.
  • the present invention presents a type of clamping mechanism for use with ski boots having a hinged door for maintaining the door in: a fully secured position.
  • the clamping device exerts force in two directions to seal opposite edges of the door against water leaks.
  • An object of the invention is to present a ski boot door clamp which is substantially hidden from view and operates quickly and satisfactorily to close the boot with a minimum of effort.
  • a still further object of the present invention is to present an over center clamp means which can be easily fastened, and has a spring for maintaining the latching lever in a proper position.
  • FIG. 1 is a side elevational view of a ski boot having a closure device made according to the present invention installed thereon;
  • FIG. 2 is a fragmentary top plan view of the device of FIG. 1 showing the forward portion of the boot, with parts in section and parts broken away;
  • FIG. 3 is a sectional view taken as on line 3-3 in FIG. 2;
  • FIG. 4 is a front sectional view taken on substantially the same line as FIG. 3 showing a door partially open;
  • FIG. 5 is an exploded sectional view showing portions of the fastening device and door.
  • FIG. 6 is a fragmentary view taken as on line 6-6 of FIG. 5.
  • a ski boot illustrated generally at 10 comprises a rigid outer shell member 11.
  • the shell member is divided into a lower portion .12 and a cuff portion 13, and the cuff portion 13 is pivotally mounted about an axis 14 to the lower portion of the boot.
  • a cable 16 is mounted on the upper edge of the cover member and a cable 17 is mounted on the lower edge, and these two cables encircle the boot and suitable over center clamps are provided for clamping the cables shut.
  • the cables hold a foot access door 19 in a closed position.
  • the door 19 comprises a portion of the cuff and a portion of the lower part of the boot, and a hinge 18 extending in an upright direction is positioned between the door and the main part of the boot adjacent the rear thereof.
  • the door 19 swings outwardly for foot access to the boot, as shown in U.S. Pat. No. 3,405,463.
  • the cable assemblies 16 and 17 together with the cover 15, which are shown in Pat. No. 3,313,046, hold the door closed satisfactorily
  • the front portions of the door, which are remote from the hinge 18, can spring slightly because there is some give even in a very rigid fiberglass reinforced epoxy shell, and leakage may occur along the lower edge of the door.
  • the hinge 18 for the door is adjacent the rear part of the boot and extends in upright direction.
  • a closure device illustrated generally at 22 has been advanced. This closure device mounts onto the door itself, and fastens to the main part of the boot which is designated 21.
  • the main part of the boot comprises a portion of the lower section 12 and a portion of the cuff section 13 and is the part of the boot to which the door is attached.
  • the closure device 22 comprises a strap member 23 which slides over the main part of the door 19 and underneath a scuff plate or protection plate 20 which is provided on the outside of the door itself for protection.
  • the protection plate 20 is a metal plate that fits over the door and is fastened with suitable devices to the door itself. It also fits over the cover section as shown in FIG. 1.
  • the door 19 has a provided relief groove or channel in which strap 23 is mounted so that it can slide easily.
  • the lower portion of the strap is formed into a I-hook section 24, and this in turn fits within an opening 25 with clip or latch plate 26 fastened to an upright edge portion 27 forming part of the sole 28 of the boot.
  • the J-hook will fit within a receptacle or opening 25 and then, by clamping an over center clamp assembly 29, the lip of the I will be pulled tight against an edge forming the upper side of the opening 25 and the strap under tension will pull the door inwardly closed so that it will abut against the main part of the boot along the junction line 31 and also pull the door downwardly so that it will abut against the upper edge of the section 27 of the sole along its junction line 32.
  • the curved section of the door tends to straighten out under this force, thus forcing the door edges toward the edges of the opening, and the latch plate and clamp assembly tend to pull the edges of the opening together.
  • the strap is a flexible metal strap that will curve around the door surface.
  • the clamp assembly 29 is shown in greater detail in FIGS. and 6.
  • FIG. 5 the channel or groove in the door 19 in which the strap rides is also shown.
  • a stud 33 is provided in the door, and this projects into an elongated slot or opening 34 in the strap for a guide means for the strap.
  • the strap is held from coming out of place by the scuff plate 20.
  • the clamp assembly 29 comprises a main mounting bolt 37 which has an eye portion that is attached rotatably to a cross pin 38 that in turn is mounted in a provided end loop 39 on the upper end of the strap 23. This end is near the top part of the instep of the boot.
  • An over center lever or buckle member 40 is provided with a cross ferrule 41 that is rotatably mounted on opposite side plates 42 of the buckle member.
  • the ferrule has a threaded cross hole therethrough.
  • the bolt 37 is threadably mounted through the hole in the ferrule so that the effective length of the bolt can be changed by turning the buckle member 40.
  • the buckle member has a slot 43 in which the bolt member can pass so that the buckle member can be pivoted about the axis of the ferrule and a lip 44 can be inserted into a mating buckle retainer 45 that is mounted onto the main portion 21 of the boot at the top of the instep, as shown in FIG. 4.
  • the member 45 has side walls 46 and a base member 47.
  • the lever or buckle member 40 can be raised up so that the lip 44 fits inside the buckle latch member 45 and then the outer end can be pushed down to make the point between the lip 44, the axis of the ferrule 41, and the axis of pin 38 go over center to lock the strap in place. This places tension in strap 23.
  • the J-hook section or portion 24 is in the latch plate 26 and the door 19 is pulled downwardly and tightly closed against the main part of the boot.
  • a torsion spring 50 is provided around the bolt 37 and pin 38 so that when the latch or buckle 40 is released, the bolt 37 will be moved about the pin 38 in direction as indicated by arrow 51 so that the latch will be lifted up out of the way, and will be ready to be inserted and wont fall in between the door and the main part of the boot as the door is being closed.
  • the clamp assembly 29 is latched first after the door is shut, and then the cover and cables 16 and 17 are closed. The cables 16 and 17 are secured with over center clamps.
  • the clamping assembly 29 is completely covered by the forward portions of the cover member, and the cables 16 and 17 then close the door tightly at the top and bottom portions.
  • the J-hook part of the strap 23 holds the mating surfaces along junction 32 tightly closed, and this edge can be gasketed with resilient gaskets if desired in order to insure that there is no water leakage.
  • the strap is carried with the door as it opens, and does not interfere when the door is open, and provides clamping force to secure opposite edges of a door.
  • the adjustment rod 37 permits the tightness of the boot door to be adjusted slightly during fitting of the boots. Conformable padding is used, and the fitting is accomplished by inserting pillows of additional padding behind the padding shown in the drawings. This method of fitting i discussed in US. Pat. No. 3,407,406.
  • the adjustable rod permits insertion of extra padding and loosening the clamp slightly so that the padding material can be worked around with the boot closed and then the clamp fully tightened. Also, the clamp can be adjusted for slight changes in foot size that may occur or for different thicknesses of socks that may be worn.
