Definitions

  • the present invention has relation to boots for skis or skates and more particularly to a boot which will hold the foot firmly and exactly so as to permit positive foot control of the wearer.
  • the boots used for skiing are made with heavy leather uppers and heavy leather soles which are originally relatively stifi.
  • the boots are fixed firmly to the skis with any of a variety of bindings.
  • the boots are designed so that they will lace up to fit the foot closely and hold the foot firmly against padding usually present between the foot and the boot either in the form of heavy socks or foam pads sewed within the inner surface of the boot.
  • the boots presently on the market provide a firm support when new but after they have been used and are wet they become soft and stretch.

  • FIGS. 1 through 3 a simplified structure of a ski boot is illustrated.
  • a boot 35 has an upper portion 36 attached to a sole 37.
  • the upper portion includes a main boot member 38 and a side flap or door 39.
  • the side flap 39 is attached to the sole 37 with a hinge 40.
  • the side flap 39 will swing outwardly from the main boot 38 to permit a foot to be inserted into the boot.
  • the sole and upper portion as well as the side flap or door are made of a very rigid material, for example, fiberglass or formed metal which will not stretch nor be affected by water, heat or other environmental factors.
  • the boot will retain its original shape under all conditions of normal usage.
  • the flap meets the main boot member along a parting line 41 and will swing away from the main member as shown by arrow 42. With the flap in its open position, pivoted away from the main boot member, the foot can be inserted in the boot and the flap re-closed to hold the foot in place.
  • the side flap 39 is held in contact with the main portion 33 through the use of a strap 43 wrapped around the upper portions of the boot and held in place with a suitable clamp or ordinary friction type strap buckle 43a. If desired an ordinary skate strap can be used for this purpose.
  • FIG. 3 illustrates a foot 44 inside the boot with the flap closed
  • the interior of the boot is lined with material or padding to hold it firmly with respect to the outer shell.
  • the padding in the fiap moves with the flap and other padding remains with the main portion of the boot when the flap is opened.
  • a very thin layer of material 45 which will stretch and generally conform to the foot shape is bonded with suitable adhesives all around the edges of the flap, at the top, as shown at 46, at the bottom 47 and front 48, and also along the portions of the flap adjacent the parting line 41.
  • a separate piece of material 45A is similarly bonded to the main portion of the boot. Two separate compartments are formed, one inside the flap and one inside the main portion of the boot. This is shown fragmentarily in FIG. 2.
  • a compartment 49 is formed between the outer wall of the flap and the ma terial 45 and this chamber is then filled with suitable material or potting compound illustrated at 50 which will flow when put into the boot in order to completely fill chamber 49, and is poured in through an opening 51 using a funnel 52.
  • Other openings can be suitably located in the outer shell of the boot, for example, at 53, which, after use, is closed with a threaded plug.
  • the material used is hardenable or expandable (a plastic foam for ex ample) after it has been placed within the compartment 49,. The material conforms to the shape of the portion of the foot in contact therewith and a very close snug fit is obtained. After the material has hardened it retains the shape of the foot and acts as a thermal insulator while the boot exactly fits the foot of the wearer.
  • Filler material will also be poured into the lower compartment on the main boot portion so that the foot is held from both sides.
  • the hardened compound in the flap compartment will move with the flap and separate along the parting line of the boot so that the foot can be removed and inserted with ease.
  • the skier need merely remove strap 43, open the boot flap 39 and insert his foot; close the boot and then replace the strap to hold the flap in place.
  • the boot is thus put on very rapidly without time consuming lacing or delay.
  • the rigid outer shell of the boot does not stretch so the boot will remain usable for years.
  • a variation of the structure shown in FIG. 3 is to prefill the compartment 49 (and also the compartment on the main boot portion) with a suitable material.
  • the material used in the compartment 49 could be an expanded polystyrene or similar foam, which can be obtained in various degrees of hardness.
  • the material could be initially shaped in general foot configuration. The wearer then inserts his foot, determines the fit, and can peen or compress the lining material in the areas where there is interference between his foot and the material. By shaping the material, for example expanded polystyrene, in the areas of interference the wearer can get an exact fit for his foot.
  • patches 53 of foam padding material that can be inserted to provide support for the foot.
  • the patches 53 are loose and can be moved to any location in the boot. Also the patches can be placed within any type of boot, even conventional boots to obtain very close fits. If desired, the patches 53 can be filled with hardenable fluid that is injected into the boot between an inner liner and the normal lining material. This gives a very close custom fit. Other padding that may be used is more fully described later.
  • FIGS. 4 through 8 there is shown a boot 60 that has a sole 61, and an upper 62.
  • the upper is split longitudinally along a parting line 63 and the sole is hinged with a longitudinal continuous hinge 64 at the bottom of the sole.
  • the boot will split open into two boot sections along parting line 63 about the axis of the hinge 64.
  • the boot sections are substantially symmetrical.
  • the boot is normally held closed with over center clamps 64- of any usual or preferred design (for example luggage clamps) adjacent top edges of the boot. The two sections of the boot fit together snugly.
  • the clamps 65 can include a lug 66 fixedly attached to one boot section, with suitable fasteners and a latch member 67 attached to the other boot section.
  • the latch member includes a pair of brackets 68 fixed to the other boot section in any usual or preferred manner.
  • a lever 69 is pivoted to the brackets and has a loop of wire 70 pivoted thereon and which extends to engage the lug 66. The lever will go over center when in position shown in dotted lines in FIG. 7 to hold the two boot sections together. As many clamps as desired can be used.
  • the boot in this form of the invention is also made of a rigid material, such as fiberglass or metal.
  • the boot is easily placed on the foot by splitting the boot open along the hinge, placing the foot inside and then reclamping it into place.
  • a sheet of liner material 72 is bonded to the boot section along the parting line 63, at the sole, as shown at 73, and along the top as shown at 74.
  • the liner material 72 on each boot section forms separate compartments that can be filled with suitable material 75 so that the liner engages the foot and holds it snugly when the sections are clamped closed.

  • the material within the pads must be able to conform to the shape of the foot and the ankle, particularly an irreguarity, such as a bunion or bone, and still retain its shape when the foot is removed so that the pads do not have to be custom fit each time the boot is put on.'The material must be firm and provide a support against sudden movement of the foot. The material must not take a set or assume a permanent shape as the foot shape changes slightly from day to day.
  • a material consisting of discrete particles surrounded with a binder of a special liquid coating, such as a wax, grease or liquid, has the desired properties of firm support, conformability, retention of shape and no leakage.
  • the material for filling the pads illustrated generally at 162 which consists of a mixture of small discrete hollow spheres of material each particle of which has its own structural strength, surrounded by a special liquid coating comprising lubricating grease (silicone base grease is best) has been found to be suitable.
  • the special liquid coating is defined for the purpose of this specification as a material which will coat the hollow balloons or particles and will not harden (it will yield under shear) at the temperatures encountered when skiing nor will it evaporate.
  • the special liquid coating material should be non-evaporating, non-toxic, non-allergenic and should not have any odor.
  • the particular ratio of grease or special liquid coating to particles is, of course, dependent on the size of the particles and the amount of rigidity desired in the pads.
  • the particles must be coated with a suflicient amount of the special liquid coating or grease to cause the particles to tend to stick together so that the pad retains the shape of the foot after the foot has been removed. This cannot be done with bags or pads filled only with liquid or air.
  • the amount of binder is preferably equal to or less than the void volume (volume of the interstitial spaces in a quantity of the particles) of the particles. If the volume of binder exceeds the void volume of the particles the bag will have substantially the flow properties of the binder (the special liquid coating) and not the desired properties.
  • the small hollow spheres of material that are utilized resemble fine flour before the special liquid coating is added to the particles.
  • the particles have a bulk density of from 3-5 pounds per cubic foot. The particles can blow away and will shift easily from external forces without the coating.
  • the special liquid coating grease binder Once the special liquid coating grease binder has been added the particles will no longer be lost through the pad seams (if the pads are sewed) by dusting nor will the resultant pad filler material voluntarily lose its configuration when the feet are removed from the boot.
  • the function of the special liquid coating is primarily to form a tacky binder that will hold the particles in place when the foot is removed and to keep the light hollow sphere particles from floating off like dust in the air during the filling process.
  • the material mixture particles having a special liquid coating
  • the material mixture has the characteristics of transmitting axial force and moving under shear. This means that sudden forces on the pads and material while skiing will not cause any changes in the pads but the material can be worked to position to fit the foot.
  • the special liquid coating is a material that does not harden at temperatures encountered while skiing.
  • the envelopes for the filler material can be made of a suitable suede leather material or other leather sewed or adhesively sealed to form the envelope shape.
  • the pads will be able to breathe slightly to permit absorption of some perspiration and transfer of air.
  • the suede leather can be coated with a product known as leather stiffener to cause the envelope to also retain its shape and prevent shifting of the material.
  • leather stiffener can be purchased from Prime Leather Finishes Co., Milwaukee 4, Wis.
  • the clamp assembly 126 located at the heel and the instep are identically constructed.
  • the length of the clamp assembly is different so as to fit the particular position in which they are located.
  • the clamp 170 at the instep extends from the toe cap indicated 171 up to a shoulder 172 adjacent the upper portions of the lower member of the boot.
  • the heel clamp 173 extends from the upper portion of the sole up to the same shoulder 172, which runs around the lower section of the boot, as will be explained later.
  • FIGS. 24-29 A typical clamp assembly is shown in FIGS. 24-29.
  • the clamp includes a latch member 17 4 which is designed to be appealing to the eye when latched in place on the boot.
  • the latch member 174 in turn is pivotally mounted to a leaf spring member 175 with a suitable rod 176. It can be seen that the latch member 174 has a plurality of lugs 177 raised therefrom which interlock with projections 178 on the leaf spring member so that the rod passes alternately through the lugs 177 on the latch member and the projections 178 on the leaf spring.
  • the projections 178 are formed so that they encircle the rod 176.
  • the opposite side edge portion of the leaf spring 175 is also formed into spaced projections 181 the edges of which are rolled around a rod 182 so that they are pivotally mounted on the rod.
  • Rod 182 also passes through lugs 183 projecting upwardly from a first mounting member 184 which is attached with suitable rivets or screws to the main portion of the boot 102.
  • the main mounting member 184 extends along the underside of the boot 102 and projects upwardly along the parting line of the boot.
  • the edge portion of the boot may be notched to receive the member 184.
  • Lugs 183 extend upwardly above the top surface of the main boot member 102 along the parting line of the boot.
  • a catch member 185 is mounted in any usual or preferred manner, for example with rivets 186 into the lower portion 103A of the flap, along the edge thereof where it mates with the main portion of the boot when in closed position.
  • the latch or the catch member 185 has lugs 187 at the outer edge thereof which are complemental to the lugs 183 on the main mounting member 184.
  • the lugs .187 interlock with the lugs 183 when the flap is in its closed position and movement in direction along the longitudinal axis of the pin 182 is prevented.
  • a main mounting member 184 has an edge surface 190 which is indented in a shallow V-shape. This edge surface 190 is facing the catch member 187.
  • the catch member 185 has an edge surface 191 that is the complement of the surface 190 and these surfaces 190 and 191 nest together with the flap assembly 103 in its closed position.
  • boot can also be filled with 1 2 that the V-shape of the surface 191 is provided by trimming away the edge portions thereof between the lugs 187 on the catch member so that these V-shape surfaces on the catch member meet with the edge surface on the lugs 183 of the main member.
  • FIG. 17 there is shown the configuration of the surfaces of members 184 and 185 that mate in the areas between lugs 133 of the main member.
  • the mating portions of these surfaces seal to prevent snow from getting into the boot.
  • the V-shaped surfaces prevent movement of the flap and main mounting member relative to each other in directions as indicated by arrow 192 in FIG. 16. This insures that the flap and boot are held solidly when the catch is closed.
  • the two members are moved as shown in FIG. 16.
  • the flap is then in closed position.
  • the latch member 174 is raised up as shown so that a hook portion, 193 thereof fits into a provided groove 194 formed on the catch member.
  • An outer end portion 195 of the latch member 174 is then pushed downwardly so that it rests against the main part of the boot 102.
  • the pivot points of rods 176 and 182 go over center and the latch member will snap into place. Then the flap is held in closed position and cannot be moved until the latch. is released.
  • the leaf spring member 175, as shown perhaps best in FIGS. 15 and 17, is slightly bowed in transverse direction. In order to permit the rods 176 and 182 to go over center, the spring will flatten out or yield until the rods go over center and then the spring will snap the catch into place with the lugs 177 resting on the top surface of the main portion of the boot.
  • hook member 193 and the groove 194 extend along the entire length of the clamps.
  • the outer end portion 195 is raised in direction as indicated by arrow 196 until the pins again go over center in the opposite way and the hook 193 can be released from the groove 194.
  • pads 125 are partially filled with material 162 and are placed within the boot.
  • the flap member 103 is closed, and the clamps 170 and 173 at the instep and heel, respectively, are latched closed, as previously described. Also, the clamp assembly 128 for the nylon strap around the cuff member is latched closed.
  • each of the pads is then displaced so as to conform to the foot in the boot. If additional material is necessary, the respective spouts 163 for each of the pads can be removed, as previously described, and additional material 162 forced into these spouts and pads. By replacing the foot into the boot several times and adding material as needed, the proper fit on the pads against the foot is obtained. The pad material will not shift unless it is subjected to external forces and the boot can be then used repeatedly without changing the filling or having to rearrange the material in the pads.
  • the pad material can be rearranged to meet this new irreguarity.
  • the foot can be placed on a suitable insole 197.
  • the insole can be of any desired or preferred construction.
  • the lower edge of the legging 198 has a hem and the hem has an elastic band or otherresilient member therein which will permit the legging to be stretched outwardly over the shoulder 172 (see FIG. 13) and snap into place in a provided groove 200.
  • the groove 200 extends around the boot completely when the flap is closed and the legging thus can be snapped into the groove to permit snow from coming in around the top portions of the lower member of the boot.
  • the upper edge portions 201 of the legging also contain a hem which has a band of elastic material therein, and constructed in a known way so that the upper edge will resiliently grip the outer surface of the ski pants of the wearer to prevent snow from entering from the top cutf.
  • Other suitable flexible covers can be placed between the upper cuff and the lower member of the boot in any usual manner. However, it has been found that the legging will work well and is quickly put into place.
  • the material in the pads will retain its shape after the foot has been removed and will always fit the foot exactly. This will give perfect control to the skier and greatly increase thewskiers skill.
  • the side location of the access flap permits solid heel clamping with the heel pads 155 and 158.
  • the human heel tapers upwardly above the sole of the foot and the pads can bulge to clamp onto the heel securely. The heel then cannot be lifted from the sole of the boot. With the side flap there is no tendency to displace the bulge of material in each pad that fits into the heel depressions at a persons heel when the foot is inserted and the flap closed.
  • a strap 167 of substantially non-stretchable material is attached to the inner wall 166 of the main boot heel pad 155 as at 167A and extends downwardly and is attached to the sole of the boot as at 167B.
  • 167 is attached to pad 155 at its bulge point.
  • a substantially non-stretchable (for example leather) strap 168 is attached to the inner wall 169 of the flap heel pad 158 as at 168A and extends downwardly and is fastened to the very bottom portion portion of the flap as at 168B.
  • the straps 167 and 168 retain the respective inner walls of the pads to which they are attached and prevent the pad bulge from rolling upwardly. This holds the heel firmly onto the sole of the boot.
  • the straps can be attached to the pads and the boot portion with suitable adhesives or mechanical fasteners.
  • heel pads terminate a distance above the sole of the boot so that pad material will not work down and cause the pad to work underneath the foot.
  • a sole plate 205 is mounted inside the outer shell of the boot.
  • the sole plate 205 is provided with suitable guide members to retain it within the boot and yet permit it to slide in a vertical direction, as shown by arrow 206.
  • the sole plate 205 is not fixedly attached with respect to the inside of the boot.
  • the sole plate has a pair of blocks 207, 207 mounted on the bottom thereof.
  • the blocks have inclined lower ramplike surfaces 208, 208 which mate with inclined upper surfaces 209, 209 of blocks 210 which form, the upper portions of a sole jacking plate 211.
  • the sole jacking plate is mounted within the hollow portion of a modified sole member 212. It can be seen that the sole member 212 has a very thin bottom panel 213 (as opposed to the sole and the panel 213 supports the sole jacking plate 211 thereon.
  • the sole jacking plate is slidably mounted along the bottom panel 213 of the hollow boot sole 212.
  • a set screw 214 is threadably mounted at the front end of the boot shell at the lower sole portion and can be threadably adjusted with a screw driver or wrench to move the boot jack in direction as indicated by arrow 215.
  • the screw will move the sole plate 205 upwardly in direction as indicated by arrow 206.
  • the end of set screw 214 engages the forward edge of the sole jacking plate and bears against this edge to force the jacking plate in direction as indicated by arrow 215.
  • the weight of the foot on the sole plate tends to move the jacking plate forwardly.
  • the foot By turning the screw 214 the foot can be tightened against the pads 125 inside the foot and the boot will be fitted more snugly to the wearers foot. This adjustment is made mainly for minor adjustments that are necessary during skiing when it is inconvenient to refill the pads, if a tighter fit is necessary. Any amount of pressure can be exerted with the set screw and thus the desired fit between the boot and the foot can be obtained.
  • the set screw can be loosened slightly to permit the sole jack to move forwardly and thereby lower the sole plate to slightly release the pressure on the foot and insure a proper, comfortable fit.
  • FIGS. 31, 32 and 33 a modified form of attaching the struts for the ankle member to the lower portion of the boot is shown. While only one side portion of the boot is shown, it is to be understood that both struts (on either side of the boot) will be attached in the same manner.
  • the main boot section 102 has its pad 156 filled with material 162 attached to the interior surface thereof, as in the previous forms of the invention.
  • a bracket is fixed to the side of the boot, as in the previous form of the invention as well.
  • the ankle cutf member 107 is mounted above the lower portion of the boot 102.
  • the culf member 107 in this form of the invention, is connected to the lower portion through an offset strut 217.
  • the strut 217 has its lower end portion positioned outside of the bracket 110.
  • the strut 217 is attached to the bracket 110 (the strut on the other side will be attached to the bracket with a disc-like rubber torsional washer 218.
  • the rubber washer can be adhesively secured to the bracket 110 and to the strut 217, if desired, or can be vulcanized to the bracket and to the strut, if desired.
  • the rubber washer as shown, is relatively thick and will permit a torsional pivotal movement about an axis substantially aligned with the ankle bone of the foot of the wearer. The torsional movement is as indicated by arrow 219.
  • the ankle assembly is therefore not freely pivotally mounted to the lower boot section in this form of the invention.
  • the torsional washer 218 will always cause the ankle culf member to tend to return to its upright or normal position no matter what direction it is pivoted during use. This fact will limit the freedom of ankle pivoting and additional rigidity in fore and aft direction can be added to the boot by proper selection of the hardness of the washer.
  • FIG. 33 illustrates three types of flexible disc washers and one type of spiral spring that can be used to attach the modified strut 217 to the bracket 110 in order to obtain the effect of having a resistance to .pivotal movement of the ankle member.
  • a solid washer 220 which is made of rubber material throughout can be used and adhesively secured in place on the strut and bracket or vulcanized in place as desired.
  • a slotted washer 221 made of suitable rubber material can also be adhesively secured in place to the strut and to the bracket. The slots 221A in the washer will make the torsional twisting of the ankle somewhat easier than the solid washer but Will still cause the cuff member to return to its normal upright position when not under pivotal stress or force.
  • a hollow washer 222 which has a pair of disc-like end members 223, 223 joined together with radially extending ribs 224 can also be used for attaching the strut 217 to the bracket 110 as shown in FIGS. 31 and 32.
  • the end members 223, 223 will be secured to the strut and bracket, respectively.
  • the struts 217 can be attached to the bracket 110 with a suitable torsion or spiral spring 225.
  • the spring will always tend to return the cult with normal position in a manner similar to the rubber torsional washers previously described.
  • the spring 225 can be attached to its outer end 226 with a suitable bolt or rivet 227 to the strut 217.
  • the inner end 228 of the spring can be attached with a suitable bolt or rivet 229 to the bracket 110. In this manner a resistance to pivotal movement of the ankle piece is accomplished.
  • the cuff member gives a very rigid holding of the ankle of a wearer in resistance to lateral bending, which is the heart of controlling the edging of skis and therefore the performance on the skis. If the boot is rigid and prevents lateral bending of the ankle absolute control of the skis can always be effected.
  • the fore and aft bending about a pivotal axis aids the skier in assuming a more relaxed position on the skis. It is thought by many persons that some type of fore and aft bending of the ski boot is necessary for proper ski control.
  • the rigid outer construction boot also is usable for skates or other athletic boots where precise control is important.
