This invention relates to improvements in ski boots and more particularly to a ski boot construction which can be manufactured with maximum efficiency while still providing highly satisfactory performance characteristics.
Ski boot constructions are commonly produced as heavy, relatively awkward, and highly expensive structures. The weight, complexity and expense results because the boots are subjected to high stress conditions during use and, therefore, must be extremely durable to provide satisfactory use and protection for the skier.
Because of the nature of ski boots, it has been difficult to provide boots which are useful for a wide range of skiing ability; For example, beginning skiers find it extremely difficult to wear a boot which is rigid whereas experts desire a boot which provides very little freedom for pivoting about the ankle joint. Manufacturers, therefore, find it necessary to provide ski boots designed for particular classes of skiers, or skiers simply use boots which are not best suited for their skills.
In order to provide some economy in manufacturing ski boots, boots have been made without taking the best fitting contours into consideration. Latch mechanisms which have been used for the boots have also been unsatisfactory from the standpoint of providing a desirable degree of adjustment to provide the best fit.
It is a general object of this invention to provide a ski boot construction which combines certain unique features resulting in a ski boot which is substantially improved over prior constructions from the standpoint of ease of manufacture and use, and from the standpoint of versatility in that the boot can be adjusted for use by beginners as well as more experienced skiers.
It is a further object of this invention to provide a ski boot which can be efficiently manufactured while still having the most desirable contours for proper fit and which can be provided with latch means having a high degree of adjustability to also improve fitting characteristics.
These and other objects of this invention will appear hereinafter and for purposes of illustration, but not of limitation, specific embodiments of the invention are shown in the accompanying drawings in which:

The invention generally relates to a latching arrangement which can be used in conjunction with various ski boot constructions. The latching construction generally involves the use of a band which is strong and flexible and having its ends secured to ski boot portions. The band preferably comprises a coil spring fit around a flexible cable or wire. The coil spring provides threads so that the band can be adjusted to provide the correct amount of holding force.
The constructions illustrated in FIGS. 1-14 in the drawings comprise a ski'boot 10 defining a sole portion 12 and a heel portion 14. The upper portion of the shoe is divided into a main body 16 and an ankle section 18.
The ankle section is pivotally connected to the body 16 by means of rivets 20. The body section 16 includes flaps 22 and 24 which overlap to provide a closure. The ankle section includes an inner flap 26 and an outer flap 28 which is divided into two sections 29 and 31. It will be noted that the lower end of the flap 26 extends over the upper end of the flap 24 so that a seal is provided all along the front of the boot.
The ankle section 18 is provided with a downwardly extending tongue 30 which is received in a slot 32 defined by the back wall 34 of the body section 16. In the embodiment of FIGS. 1 and 2, the tongue 30 defines an elongated opening 36, and this opening is positioned opposite holes 38 defined in the wall section 40 of the back wall 34. These holes are adapted to receive the end 42 of pin 44. The pin is mounted in a bracket 46 which is attached to the body 16. A spring 48 extends between the bracket and a shoulder 50 on the pin to normally urge the end 42 into the opening 36 defined by the tongue. The handle 52 of the pin is provided so that the pin can be pulled outwardly to release the pin from the opening 38 in which it is received.
As best shown in FIG. 4, the back wall 34 of the body section 16 defines a substantially V-shaped cut-out portion 37. This cut-out portion is provided to accommodate the tendency of this section of the back wall to squeeze together in response to forward motion of the tibia-fibula shin.
The bracket 46 is attached to the body 16 by means of opposed arms 54 which extend around the sides of the body. The arms may be riveted to the body at 56 to provide a pivotal connection whereby the pin 44 can be moved into engagement with a different hole 38. The position of the pin 44 determines the degree of allowable movement of the ankle section. Thus, the location of the pin in the lower hole 38 would substantially lock the tongue 30, and thereby restrict movement of the ankle section. The upper hole 38 will provide a degree of freedom corresponding with the length of the opening 36 in the tongue. An intermediate position is provided for the pin 44, and it will be appreciated that the number of positions for adjustment as well as the size of the opening 36 can be varied.
In the embodiment shown in FIG. 6, the holes 38 are threaded, and a threaded pin 58 is provided. The extent of allowable movement is then controlled depending upon which of the threaded holes 38 is employed.
A preferred arrangement for a limiting device is shown in FIGS. through 14. This limiting device includes a mounting bracket 110 having a central portion 112 dimensioned to fit snugly against the enlarged portion 114 defined by the back wall 34 of the boot. Openings 118 are defined by the flanges 120 provided on the legs 122 of the bracket. These openings provide means for securing the bracket to the boot.
The central portion 112 of the bracket defines outwardly extending shoulders 124 which are received in the grooves defined by the arms 126 of sliding bracket 128. The bracket 128 carries a spring 130 having an inturned portion 132 which rests in the seat 134 defined by the bracket. A downwardly extending leg 136 of the spring extends through a slot 138. The end of the leg 136, therefore, extends into contact with the upper surface of the central portion 112 defined by the stationary bracket 110.
A locking handle 140 is pivotally connected to the upstanding arms 142 of the movable bracket 128 by means of a pin 144. As best shown in FIG. 11, the handle defines a cam surface in the area of the spring 130 and in the position shown, the leg 136 is being forced downwardly. By raising the handle in the direction of the arrow 146, the pressure on the spring will be gradually relieved. The central portion 112 of the bracket 110 defines a plurality of V-shaped grooves 148 which receive the end of the leg 136 for locking the sliding bracket in position relative to the stationary bracket.
The movable bracket 128 carries a pin 150 which is adapted to extend into the opening 36 defined by the tongue 30. In this embodiment, the tongue 30 extends into the opening 152 defined by the enlarged portion 114 in the back wall of the boot.
In the preferred form of the invention, the body 16 comprises a single molded piece of polyurethane. The molding operation can be efficiently carried out, particularly since the flaps 22 and 24 can be integrally molded. The ankle section 18 including the flaps 26 and 28 and tongue 30 can also be molded as a single piece with material such as polyurethane. The assembly operation for these two pieces merely involves the attachment of the latch hardware, the rivets for achieving pivoting, and the pin mechanism.
The interior contours of the molded pieces 16 and 18 can be determined by considering the matural foot contours. Thus, the design of these pieces permits efficient production without sacrificing the natural interior contours. The entire interior may be lined with a cushion having a tongue portion 62 attached at 64. This cushion is also designed so that the natural shape of the foot will be accommodated.
The boot design also takes into consideration the malleolus or ankle bone position since the pivot axis for the ankle section 18 substantially corresponds with this bone position. This is particularly apparent when considering FIGS. 5 and 6. It will be noted in this connection that the pivot axis is different on the opposite sides of the boot. The rivet 20 on the outside of the boot is positioned in accordance with the position of the lateral malleolus while the rivet 20 on the inside is positioned in accordance with the position of the medial malleolus. These positions can be calculated for a given boot size in accordance with known anatomical standards.
Although the material employed for the boot is relatively stiff, it is desirable to provide additional stiffening means 65 in the sole of the boot. This stiffening means may consist of a piece of wood, metal or plastic molded integrally with the boot and dimensioned to extend adjacent the exterior surfaces on the molded part.
Because of the thickness of the sole 12 and the rela tive stiffness of polyurethane, particularly if the stiffener 65 is utilized, bending of the boot in the top or vamp area 66 cannot be easily achieved. In a modified form of the invention, the sole 12 defines a radius bottom as shown at 68. This provides a rocker affect which is desirable particularly because of the stiffness of the shoe and to provide proper functioning of the safety bindings. Thus, if the shoe sole were flat, pivoting movement relative to the ski would take place at the front edge and, this fulcrum point is not satisfactory for achieving release of the bindings at a proper stress level.
FIGS. 7 through 9 illustrate an improved latch construction employed for securing the flaps 24 and 28 relative to the shoe body when these flaps are in overlapping relationship with the underlying flaps 22 and 26. The latching mechanisms are particularly useful with the boot construction of this invention; however, these mechanisms have definite utility with respect to boot constructions of other designs.
The latch arrangement comprises a plate 70 which is riveted to a shoe section 72 comprising a portion of one of the flaps 24 or 28. The rivet 74 includes a reduced diameter portion 76 which permits pivotal movement of the plate 70.
Holding brackets are formed by means of U-shaped members 78 secured by the rivets 80 to plates 70. Corresponding Ushaped members 82 are adapted to be received within the walls of the members 78. Openings 84 are defined by the walls of the member 78 for receiving the ends 86 of securing bands 88. The bifurcated side walls 90 of the U-shaped member 82 provide openings permitting location of this member within the member 78. A weld or other suitable securing arrangement may be provided for holding the members 78 and 82 together.
The bracket arrangement provides open side walls whereby nuts 92 fitted around the ends 86 of the bands may be rotated with the fingers. In the embodiment illustrated, the bands are formed by means of a centrally located wire 94 and a coil 96 extending along the length of the wire. The outer periphery of the cable provides a thread for interfitting with the internal threads of the nuts 92.
The loop provided by the bands 88 is adapted to be held by means of a lever 98. The lever defines teeth 100 which are engaged by the loop in the band. After engagement with the loop, the lever is pivoted about the mounting 102 thereby locking the loop in position. The nuts 92 can be rotated for fine adjustment of the band prior to pivoting of the lever to the locked position. This provides a highly suitable arrangement for achieving a snug and comfortable attachment of the flaps on each boot. Thereafter, the wearer adjusts the limiting device with the position usually depending upon skiing experience. Thus, a beginner usually requires a larger degree of freedom, and this can be accomplished by inserting the pin 44 or 58 in the upper hole or by eliminating use of the pin altogether whereby the tongue will be free to move in the slot 32. In the case of a more experienced skier, an intermediate to lower hole would be utilized.
Irrespective of the amount of pivoting allowable, the pivoting action will take place about the axis of the rivet which provides a natural pivot position from the standpoint of the ankle joint of the wearer. In addition to the control provided for pivotal movement, the construction provides a high degree of lateral stability. The use of molded polyurethane and the design of the overlapping portions of the body 16 and ankle section 18 are important in this regard.
FIG. 15 illustrates a ski boot construction 210 comprising an alternative form of the invention. This boot includes a sole portion 212, a heel 214 and an upper divided into a main body portion 216 and an ankle section 218. The ankle section is pivotally connected at 220 in the manner previously described. I
A limiting arrangement for determining the extent of allowable pivotal movement is illustrated in FIGS. 17 and 18. As in the previously described arrangement, this limiting arrangement includes a tongue 222 attached to the ankle section which is received within a pocket 224 formed in the main body of the boot. A plurality of openings 226 are formed in the main body and are aligned on either side of the pocket to permit the insertion of the arms 228 and 229 of clip 230. As in the previously described embodiments, the position of the clip will determine the extent of allowable pivotal movement. A slot 232 is formed in the tongue to receive the arms of the pin. The arm 229 is provided with a pivoting end portion 231 whereby the clip can be locked in place after it is properly positioned.
The clip 230 is designed to accomplished all of the advantages previously described with reference to the limiting means. Thus, by inserting the arm 229 sothat only this arm extends through slot 232 with the arm 228 being exposed outside the rear wall of the boot (as shown in dotted lines in FIG. 18), a limiting arrangement as previously described is achieved. When the clip is inserted as shown in solid line in FIG. 18, a distinct limiting arrangement is achieved since pivoting movement is allowed but to a lesser extent. Thus, in this position the arm 229 limits downward movement of the tongue while the arm 228 limits upward movement.
Additional versatility is achieved when the clip is positioned as shown in FIG. 19. In this instance, the arms 228 and 229 confine the end portion 233 of the tongue. Accordingly, the tongue is restricted against movement in either direction. The position at which the tongue is held and, accordingly, the position of the ankle section with respect to the body section can be varied depending upon the location of the clip.
As best illustrated in FIGS. 20 and 21, the ski boot structure includes a tongue 234 which is attached at the toe section of the boot by means of fasteners 236. This tongue spans a gap defined between the opposing edges 238 and 240 of the ski boot body section 216. The ankle section 218 includes a similar gap defined between the opposing edges 242 and 244. A cushioned liner 246 is situated within the boot, and this liner preferably completely encloses the wearers foot. A sponge backing 247 may be applied to the tongue to complement the liner.
The ski boot body preferably comprises a single molded piece of relatively stiff material, for example, a stiff polyurethane. The ankle section may be formed of the same material, however, a different material, which may be either a softer or stiffer plastic, could be used in this area. The tongue 234 comprises a molded plastic piece having a foot section 248 and an ankle section 250. The foot section of the tongue is located over the top of the foot and it includes a central raised portion 251 which tits in the gap between the edges 238 and 240. The ankle section 250 of the tongue is situated adjacent the front of the ankle and it includes a raised portion 253 situated between the edges 242 and 244. The area of the tongue between the stiffeners is preferably relatively flexible and grooves 252 and darts 255 may be employed to increase the flexibility.
It will be noted when considering FIGS. 15 and 20 that the portions 251 and 253 of the tongue 234 define sides 254 and edges 257 which provide a sealing arrangement in combination with the opposing portions of the main body and ankle sections of the boot. As will be explained, this overlapping relationship cooperates with the securing means for the boot to create a closure which will prevent any moisture from entering from outside the boot.
The securing means of the invention are preferably associated with both the main body portion 216 and ankle section 218. It will be appreciated that the number of these members will depend on the size of the boot, cost factors, etc. The particular design illustrated can thus be varied considerably depending upon requirements.
The securing means include latch portions provided by the bifurcated members 256. These latch members are adapted to removably receive the balls 258 secured to the bands 260 which extend over the boot. The opposite ends of the bands 260 are attached to assemblies 262.
Each of the assemblies comprises a lever arm 264 pivotally connected at 266 to a bracket 267. These arms are each provided with an intermediate bore for receiving pivot pins 268. These pivot pins are attached to internally threaded members 270 whereby the members 270 are adapted to pivot relative to the lever arms.
The bands 260 should be flexible in nature and'capable of resisting tensile forces whereby the bands can be held taut between the members 256 and 262. These characteristics, plus the provision of external threads are best achieved with the design illustrated in FIG. 7
wherein an internal cable or wire is surrounded by a coil spring. This arrangement provides the necessary tensile strength and flexibility with the turns of the coil providing the threaded exterior. The opposite ends of the coil spring are fastened to the internal cable to maintain the desired relationship.
In the use of the structure illustrated, the lever arms 264 are located in the open position shown at the top of FIG. 16 whereby the balls 258 are released from engagement with the latch member 256. In this condition, the user can readily pull the ski boot onto his foot. It will be noted that the tongue 234 can be pivoted outwardly from between the opposing boot and ankle portions to increase the size of the access opening for insertion of the foot.
Once the foot is in place, the balls 258 are located on the seats provided by the latch members 256 with the bands 260 extending between the arms 272 of the latch members. The levers 264 are then pivoted to the closed position shown at the bottom of FIG. 16. It will be noted that this pivoting movement moves the axis of the pins 268 from one side of the lever axis to the other. Depending upon the position of the band 260 relative to its associated threaded member 270, the movement of the lever from the open to the closed position will draw a latch member 256 toward the bracket 262. This will, of course, bring the edges 238 and 240 closer together in the main body portion 216 while the edges 242 and 244 will be drawn closer together in the ankle section 218 when latching occurs in the respective areas. A V-shaped cut-out portion 261 is provided in the foot section to prevent buckling when closing occurs.
In the initial use of a ski boot, the position of the bands 260 relative to the members 270 will have to be adjusted. This can be accomplished by simply releasing the lever arm which will loosen an associated band whereby the band can be easily rotated to either shorten or lengthen the portion of the band between the members 256 and 262. Even after the boot has been worn for a period of time, the securing means can be very simply adjusted by releasing the various lever arms and, in this connection, all of the bands are adjustable independent of each other which permits selective and fast adjustment.
The rotation of a band within a member 270 readily moves the band inwardly and outwardly as desired. It will be appreciated that additional adjustment could be accomplished by rotating the balls 258 to move the balls along the band; however, this arrangement is not a necessary feature. The fact that the bands are flexible causes them to conform to the curvature of the foot whereby the bands do not cut" into the foot during use.
The tongue and boot design, coupled with the design of the securing means provides an ideal arrangement for providing a completely comfortable fit while completely sealing the interior of the shoe. In the locked position, the opposing boot and ankle sections are maintained in tight engagement with the tongue portions 254. It will be noted that the portions 254 have a substantial width to allow for various positions of the boot edges without disturbing the sealing relationship.
It will be understood that various changes and modifications may be made in the above described construction which provide the characteristics of this invention without departing from the spirit thereof particularly as defined in the following claims.
