Definitions
- the invention refers to footwear, in particular a sports boot, and more particularly a boot adapted to be retained on a sport apparatus such as a snowboard or other gliding board.
- Boots of the aforementioned type can be used in fields such as snowboarding, skiing, snowshoeing, roller skating, but also walking and hiking, and the like.
- a flexible boot makes it easier to walk, execute acrobatic maneuvers, and to apply and receive forces to and from the board while being supported by and operating the board.
- FIGS. 1 and 2 are part of an annexed drawing shown in detail hereinafter.
- the boot 1 includes a sole assembly 2 and an upper 3 .
- the upper 3 includes a first envelope 4 , or outer envelope, which extends along a lower portion 5 and an upper portion 6 of the boot.
- the lower portion 5 is adapted to cover the foot of a user, whereas the upper portion 6 is adapted to cover the ankle and a portion of the lower leg.
- the boot 1 also includes an inner envelope 7 , or slipper. The use of the slipper is not systematic, or mandatory, as it is not included in certain footwear.
- one of straps typically encloses the wearer's instep and the instep area of the boot.
- the strap extends along the midpoint 8 .
- the strap covers the bulges 9 , 10 .
- the strap although flexible, is inextensible. Consequently, the bulges 9 , 10 are compressed on the wearer's foot through the thickness of the upper 3 .
- the bulges partially tend to project inward of the boot 1 .
- rigid areas of the upper, defined by the bulges press against the foot.
- This phenomenon creates sources of pain and can cause injuries, which generally occur in cases of extreme use, i.e., involving an acrobatic or an at least a demanding sports activity.
- the rigid areas, or hard spots, on the upper can hamper the operation of the board, because the forward bending of the upper is hindered. This results, for example, in unnecessary fatigue, inaccurate transmission of steering forces and the receipt of sensory information to the wearer, or waste of time in executing the movements, in particular for the forward bending.
- the transverse cross section of the boot increases in the area of the midpoint 8 , thereby resulting in insufficient transverse foot support, which also hinders the steering of the board.
- the invention seeks in particular to improve a flexible boot that includes a lower portion and an upper portion.
- the invention reduces, and can even completely eliminate, hindrance to the operation of a gliding or rolling board, for example, that results from difficulty in bending the upper.
- the invention facilitates the bending of the upper, in particular the forward bending, without modifying the general properties of the boot, with respect to foot support forces, for example, related to operating the board.
- the invention completely eliminates, or at least to substantially reduces the risk of injuries, such as those that can occur during extreme use.
- the invention expands the range of applications for the boot.
- the invention improves the transverse support of the foot in the boot, in particular in the area of the midpoint between the lower portion and the upper portion.
- the invention provides a boot including a sole assembly and an upper, the boot extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and heightwise from the sole assembly up to an upper end, the boot including a first envelope that extends along a lower portion and an upper portion.
- the first envelope includes a front lower flap, a rear lower flap, as well as a rear upper flap, the front lower flap partially extending along the rear lower flap, and the rear upper flap partially extending along the rear lower flap, the front lower flap and rear upper flap extending along the same surface of the rear lower flap.
- the juxtaposing of the rear lower flap and the front lower flap demarcates a front juxtaposition zone.
- the juxtaposing of the rear lower flap and the rear upper flap demarcates a rear juxtaposition zone.
- the rear lower flap is either closer to or further spaced from the inside of the boot than the front lower and rear upper flaps.
- the front lower flap and rear upper flap can be said to be offset with respect to the rear lower flap, while being further outside or further inside of the first envelope. Therefore, a flexional deformation of the boot moves the front lower flap and rear upper flap along the same surface of the rear lower flap.
- the rear lower flap is then not biased, or is only slightly biased, in the direction in which it is not compressed along a longitudinal direction of the boot. Consequently, the transverse cross section of the boot, in the area of the midpoint between the lower and upper portions, remains substantially constant. Practically, this means that no bulge is formed at the midpoint of the zones. If a linkage or strap encloses this midpoint, then the tightening of the boot remains constant in this area in spite of a bending of the boot.
- the boot also provides for the elimination, or at least a substantial reduction, in the risk of injury.
- the boot according to the invention is an improvement to the prior art, with a broader field of application.
- FIG. 1 is a perspective front view of a boot according to the prior art
- FIG. 2 is a cross section along the line II-II of FIG. 1 ;
- FIG. 3 is a perspective front view of a boot according to a first embodiment of the invention.
- FIG. 4 is a lateral side view of the boot of FIG. 3 according to its natural, i.e., unbiased, configuration
- FIG. 5 is a medial side view of the boot of FIG. 3 according to its natural configuration
- FIG. 6 is a view similar to FIG. 4 , in a case in which the boot is biased in forward bending;
- FIG. 7 is a cross section along the line VII-VII of FIG. 6 ;
- FIG. 8 is similar to FIG. 4 , for a second embodiment proposed for the invention.
- the first embodiment described hereinafter relates more specifically to snowboard boots.
- the invention applies to other fields, such as those mentioned hereinabove.
- the first embodiment is described below with reference to the illustrations in FIGS. 3 to 7 .
- a snowboard boot 21 is adapted to receive the foot of the wearer, i.e., the foot of the rider.
- the boot 21 includes an outer sole assembly 22 and an upper 23 .
- the boot 21 extends lengthwise from a rear end, or heel 24 , to a front end, or tip 25 .
- the boot 21 also extends widthwise, between a lateral side 26 and a medial side 27 .
- the boot 21 extends heightwise, from the sole assembly 22 up to an upper end 28 .
- the boot 21 includes a first envelope 31 , which demarcates the outer portion of the upper 23 .
- the first envelope 31 includes a lower portion 32 , adapted to cover the foot, as well as an upper portion 33 , adapted to surround the ankle and a portion of the lower leg of the user.
- the envelope 31 is part of the upper 23 and, as such, demarcates the upper end 28 .
- the envelope 31 is affixed to the sole assembly 22 by any means, such as an adhesive, i.e., glue or welding, or stitching, for example.
- the first envelope 31 includes a front lower flap 41 , 51 , a rear lower flap 42 , 52 , as well as a rear upper flap 43 , 53 .
- Each of the front lower flap and the rear lower flap comprises at least part of the lower portion 32 of the envelope, and the rear upper flap comprises at least part of the upper portion of the envelope.
- the front lower flap 41 , 51 partially extends the rear lower flap 42 , 52
- the rear upper flap 43 , 53 partially extends the rear lower flap 42 , 52 .
- the front lower flap 41 , 51 and rear upper flap 43 , 53 extend along the same surface 45 , 55 of the rear lower flap 42 , 52 .
- the front lower flap and the rear upper flap extend along the same surface level along the rear lower flap, i.e., thickness-wise of the upper. That is, regardless of the construction of the rear lower flap, i.e., whether it is made in one or plural pieces, i.e., whether constituting a single continuous surface or comprising one or more joined surfaces, the rear upper flap and the front lower flap are both situated against, and partially cover, the same surface level of the rear lower flap.
- the same surface level is that of the outer side of the rear lower flap, whereby the rear upper flap and the front lower flap overlap the rear lower flap.
- the front lower flap 41 , 51 and rear upper flap 43 , 53 are opposite the same surface 45 , 55 of the rear lower flap 42 , 52 , respectively.
- the surface 45 , 55 is only partially traversed by the flaps; that is, a free zone 46 , 56 remains between the front lower flap 41 , 51 and rear upper flap 43 , 53 , respectively. Consequently, a flexional deformation of the boot 21 moves the front lower flap 41 , 51 and rear upper flap 43 , 53 along the same surface 45 , 55 of the rear lower flap 42 , 52 , respectively.
- the front bending therefore causes the front lower flap 41 , 51 and rear upper flap 43 , 53 to come closer together.
- the bending temporarily increases the surface areas of the front and rear juxtaposition zones.
- each rear lower flap 42 , 52 is not subject to compressive stresses along a longitudinal direction of the boot. Therefore, the transverse cross section of the boot remains substantially constant in the area of the rear lower flap(s) 42 , 52 . Consequently, the tightening of the boot, via an outer linkage, or strap (not shown), and acting in the area of the flexion crease, or of the instep, therefore in the area of the rear lower flap(s) 42 , 52 , allows the upper 3 to have great bending freedom.
- the front lower flap 41 , 51 is adapted here to partially cover the rear lower flap 42 , 52
- the rear upper flap 43 , 53 is adapted to partially cover the rear lower flap 42 , 52 .
- the surface 45 , 55 of the rear lower flap, in the area of which the front lower flap 41 , 51 and rear upper flap 43 , 53 engage is an outer surface 45 , 55 . Consequently, the rear lower flap, in the front and rear juxtaposition zones, is closer to the inside of the boot than the front lower and rear upper flaps.
- the first envelope 31 is adapted to include three flaps 41 , 42 , 43 and 51 , 52 , 53 , respectively, for each of the sides 26 , 27 . More precisely, as it appears in FIG. 4 for the lateral side 26 , the first envelope 31 includes a lateral front lower flap 41 , a lateral rear lower flap 42 , as well as a lateral rear upper flap 43 , the lateral front lower flap 41 partially covering the lateral rear lower flap 42 , and the lateral rear upper flap 43 partially covering the lateral rear lower flap 42 . In the same manner, according to FIG.
- the first envelope 31 includes a medial front lower flap 51 , a medial rear lower flap 52 , as well as a medial rear upper flap 53 , the medial front lower flap 51 partially covering the medial rear lower flap 52 , and the medial rear upper flap 53 partially covering the medial rear lower flap 52 .
- This arrangement provides the boot 21 with the same bending ability for each of the lateral 26 and medial 27 sides. Consequently, front bending is facilitated.
- the arrangement of the various flaps 41 to 43 and 51 to 53 is selected with the purpose of obtaining two combined effects, first, easier bending of the upper 23 , as mentioned hereinabove, and, second, precise and comfortable foot support.
- the front lower flap 41 has a fastening edge 61 opposite a free edge 62 , the edges 61 , 62 being connected by a rear edge 63 and by a front edge 64 .
- the fastening edge 61 is affixed to the sole assembly 22 , for example by means of an adhesive, such as glue or weld, and/or stitching.
- the free edge 62 as described further hereinafter, can be biased to reversibly tighten the upper 23 , i.e., to selectively tighten or loosen the upper with respect to the wearer's foot.
- the position of the connecting edges 63 , 64 is referenced with respect to a transverse plane J of the boot 21 , which is level with the frontal surface 59 of the upper portion 33 .
- the plane J is tangent to the frontal surface 59 , considered when the boot 21 has its natural shape, i.e., its non-biased shape.
- the frontal surface 59 is the subdivision of the portion 33 that is the closest to the tip 25 .
- the rear edge 63 of the lateral front lower flap 41 extends rearward of the transverse plane J, while remaining spaced apart from the heel 24 .
- the rear edge is rearward by an amount ranging between 1 and 50 millimeters (mm) with respect to the transverse plane J.
- the front edge 64 extends forward of the transverse plane J, while remaining spaced apart from the tip 25 .
- the front edge is forward by an amount ranging between 30 and 120 mm with respect to the transverse plane J.

- the front edge 75 is in the area of, or proximate, the transverse plane J, mentioned above, and can intersect the transverse plane J.
- the edge 75 can also be provided to be rearward or forward of the transverse plane J, insofar as it remains forward of the rear edge 63 of the flap 41 .

Description
- The instant application is based upon the French priority Patent Application No. 09.06051, filed Dec. 15, 2009, the disclosure of which is hereby incorporated by reference thereto, and the priority of which is hereby claimed under 35 U.S.C. §119.
- 1. Field of the Invention
- The invention refers to footwear, in particular a sports boot, and more particularly a boot adapted to be retained on a sport apparatus such as a snowboard or other gliding board.
- 2. Background Information
- Boots of the aforementioned type can be used in fields such as snowboarding, skiing, snowshoeing, roller skating, but also walking and hiking, and the like.
- For certain disciplines, it is advantageous to have a flexible boot. In snowboarding, for example, a flexible boot makes it easier to walk, execute acrobatic maneuvers, and to apply and receive forces to and from the board while being supported by and operating the board.
- A snowboard boot according to the prior art is illustrated with reference to
FIGS. 1 and 2 , which are part of an annexed drawing shown in detail hereinafter. - According to
FIG. 1 , theboot 1 includes asole assembly 2 and an upper 3. The upper 3 includes afirst envelope 4, or outer envelope, which extends along alower portion 5 and anupper portion 6 of the boot. Thelower portion 5 is adapted to cover the foot of a user, whereas theupper portion 6 is adapted to cover the ankle and a portion of the lower leg. As shown more clearly in the cross-sectional view ofFIG. 2 , theboot 1 also includes aninner envelope 7, or slipper. The use of the slipper is not systematic, or mandatory, as it is not included in certain footwear. - During use, i.e., when operating the board, the user frequently bends and then extends his/her legs. During bending, the
upper portion 6 is inclined forward towards thelower portion 5. Consequently, theouter envelope 4 deforms transversely at themidpoint 8 between the lower and upper portions. The deformation temporarily createstransverse deformations 9, 10, or bulges, which disappear when theboot 1 reassumes its natural, non-biased, shape. These bulges 9, 10 cause certain problems. - Indeed, in the situation of the
boot 1 being retained on a sports apparatus, such as a snowboard or other gliding board, by means of the straps of a strap-in binding, one of straps typically encloses the wearer's instep and the instep area of the boot. In such a case, the strap extends along themidpoint 8. The strap, then, covers thebulges 9, 10. However, the strap, although flexible, is inextensible. Consequently, thebulges 9, 10 are compressed on the wearer's foot through the thickness of the upper 3. The bulges partially tend to project inward of theboot 1. As a consequence, rigid areas of the upper, defined by the bulges, press against the foot. This phenomenon creates sources of pain and can cause injuries, which generally occur in cases of extreme use, i.e., involving an acrobatic or an at least a demanding sports activity. Also, the rigid areas, or hard spots, on the upper can hamper the operation of the board, because the forward bending of the upper is hindered. This results, for example, in unnecessary fatigue, inaccurate transmission of steering forces and the receipt of sensory information to the wearer, or waste of time in executing the movements, in particular for the forward bending. - When no strap encloses the instep, or when the strap is not tightened, the transverse cross section of the boot increases in the area of the
midpoint 8, thereby resulting in insufficient transverse foot support, which also hinders the steering of the board. - In view of the preceding, the invention seeks in particular to improve a flexible boot that includes a lower portion and an upper portion.
- More specifically, the invention reduces, and can even completely eliminate, hindrance to the operation of a gliding or rolling board, for example, that results from difficulty in bending the upper. Thus, the invention facilitates the bending of the upper, in particular the forward bending, without modifying the general properties of the boot, with respect to foot support forces, for example, related to operating the board.
- Further, the invention completely eliminates, or at least to substantially reduces the risk of injuries, such as those that can occur during extreme use. In other words, the invention expands the range of applications for the boot.
- Still further, the invention improves the transverse support of the foot in the boot, in particular in the area of the midpoint between the lower portion and the upper portion.
- To this end, the invention provides a boot including a sole assembly and an upper, the boot extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and heightwise from the sole assembly up to an upper end, the boot including a first envelope that extends along a lower portion and an upper portion.
- At at least one of the lateral and medial sides of the boot of the invention, the first envelope includes a front lower flap, a rear lower flap, as well as a rear upper flap, the front lower flap partially extending along the rear lower flap, and the rear upper flap partially extending along the rear lower flap, the front lower flap and rear upper flap extending along the same surface of the rear lower flap.
- The juxtaposing of the rear lower flap and the front lower flap demarcates a front juxtaposition zone. Similarly, the juxtaposing of the rear lower flap and the rear upper flap demarcates a rear juxtaposition zone. In these two zones, the rear lower flap is either closer to or further spaced from the inside of the boot than the front lower and rear upper flaps.
- Because the inside of the boot receives the foot, the front lower flap and rear upper flap can be said to be offset with respect to the rear lower flap, while being further outside or further inside of the first envelope. Therefore, a flexional deformation of the boot moves the front lower flap and rear upper flap along the same surface of the rear lower flap. A forward bending, which brings the upper end of the boot towards its front end, therefore results in bringing the front lower flap and rear upper flap relatively closer to one another. The rear lower flap is then not biased, or is only slightly biased, in the direction in which it is not compressed along a longitudinal direction of the boot. Consequently, the transverse cross section of the boot, in the area of the midpoint between the lower and upper portions, remains substantially constant. Practically, this means that no bulge is formed at the midpoint of the zones. If a linkage or strap encloses this midpoint, then the tightening of the boot remains constant in this area in spite of a bending of the boot.
- Among the resulting advantages is a great bending freedom for the upper, whereby the operation of the board is slightly hindered, or is not hindered at all.
- The boot also provides for the elimination, or at least a substantial reduction, in the risk of injury.
- Generally speaking, the boot according to the invention is an improvement to the prior art, with a broader field of application.
- Other characteristics and advantages of the invention will be better understood from the description that follows, with reference to the annexed drawings partially illustrating the prior art, as well as two non-limiting embodiments of the invention, and in which:

- The first embodiment is described below with reference to the illustrations in
FIGS. 3 to 7 . - As shown in
FIG. 3 , asnowboard boot 21 is adapted to receive the foot of the wearer, i.e., the foot of the rider. - In a known fashion, the
boot 21 includes an outersole assembly 22 and an upper 23. Theboot 21 extends lengthwise from a rear end, orheel 24, to a front end, ortip 25. Theboot 21 also extends widthwise, between alateral side 26 and amedial side 27. Finally, theboot 21 extends heightwise, from thesole assembly 22 up to anupper end 28. - The
boot 21 includes afirst envelope 31, which demarcates the outer portion of the upper 23. Thefirst envelope 31 includes alower portion 32, adapted to cover the foot, as well as anupper portion 33, adapted to surround the ankle and a portion of the lower leg of the user. Theenvelope 31 is part of the upper 23 and, as such, demarcates theupper end 28. Theenvelope 31 is affixed to thesole assembly 22 by any means, such as an adhesive, i.e., glue or welding, or stitching, for example. - According to the invention, for at least one of the lateral 26 and medial 27 sides, the
first envelope 31 includes a frontlower flap lower flap upper flap lower portion 32 of the envelope, and the rear upper flap comprises at least part of the upper portion of the envelope. The frontlower flap lower flap upper flap lower flap lower flap upper flap same surface lower flap FIGS. 3-7 , the same surface level is that of the outer side of the rear lower flap, whereby the rear upper flap and the front lower flap overlap the rear lower flap. - In other words, the front

Nos. 6,679,516 and 6,773,020, the disclosures of which are hereby incorporated by reference thereto in their entireties.
- The front
lower flap lower flap upper flap lower flap surface lower flap upper flap outer surface - According to the first illustrated embodiment, the
first envelope 31 is adapted to include threeflaps sides FIG. 4 for thelateral side 26, thefirst envelope 31 includes a lateral frontlower flap 41, a lateral rearlower flap 42, as well as a lateral rearupper flap 43, the lateral frontlower flap 41 partially covering the lateral rearlower flap 42, and the lateral rearupper flap 43 partially covering the lateral rearlower flap 42. In the same manner, according toFIG. 5 for themedial side 27, thefirst envelope 31 includes a medial frontlower flap 51, a medial rearlower flap 52, as well as a medial rearupper flap 53, the medial frontlower flap 51 partially covering the medial rearlower flap 52, and the medial rearupper flap 53 partially covering the medial rearlower flap 52. This arrangement provides theboot 21 with the same bending ability for each of the lateral 26 and medial 27 sides. Consequently, front bending is facilitated. - The arrangement of the
various flaps 41 to 43 and 51 to 53 is selected with the purpose of obtaining two combined effects, first, easier bending of the upper 23, as mentioned hereinabove, and, second, precise and comfortable foot support. - With initial reference to the lateral side, according to
FIG. 4 , the frontlower flap 41 has afastening edge 61 opposite afree edge 62, theedges rear edge 63 and by afront edge 64. Thefastening edge 61 is affixed to thesole assembly 22, for example by means of an adhesive, such as glue or weld, and/or stitching. Thefree edge 62, as described further hereinafter, can be biased to reversibly tighten the upper 23, i.e., to selectively tighten or loosen the upper with respect to the wearer's foot. - The position of the connecting
edges boot 21, which is level with thefrontal surface 59 of theupper portion 33. The plane J is tangent to thefrontal surface 59, considered when theboot 21 has its natural shape, i.e., its non-biased shape. Thefrontal surface 59 is the subdivision of theportion 33 that is the closest to thetip 25. - According to the first embodiment proposed, the
rear edge 63 of the lateral frontlower flap 41 extends rearward of the transverse plane J, while remaining spaced apart from theheel 24. For example, the rear edge is rearward by an amount ranging between 1 and 50 millimeters (mm) with respect to the transverse plane J. In the same manner, thefront edge 64 extends forward of the transverse plane J, while remaining spaced apart from thetip 25. For example, the front edge is forward by an amount ranging between 30 and 120 mm with respect to the transverse plane J. However, the distance between thefront edge 64 and thetip 25 is equal to or greater than 40 mm. Consequently, thefastening edge 61 measures between 30 and 140 mm, a value between 60 and 110 mm yielding good results. - The rear
lower flap 42 has afastening edge 71 opposite afree edge 72, theedges heel zone 73 and anupper edge 74 on the side of theheel 24, and by afront edge 75 on the side of the frontlower flap 41. Here again, thefastening edge 71 is affixed to thesole assembly 22 in a manner described above with reference to fastening edge of the frontlower flap 41. Thefree edge 72 can be biased to reversibly tighten the upper 23. - The position of the
upper edge 74 is referenced with respect to thelimit 78 between thelower portion 32 and theupper portion 33. Thislimit 78 is located in the area of the flexion crease of the foot. Thus, essentially, the distance that separates thesole assembly 22 from theupper edge 74, of the lateral rear lower flap, is substantially the same as the distance between thesole assembly 22 and thelimit 78. - The
heel zone 73 extends in the area of theheel 24. The lateral rearlower flap 42 and medial rearlower flap 52 are co-extensive, i.e., continuous, in the area of thezone 73. This provides continuity to the upper 23 in the area of the heel. - Finally, the
front edge 75 of the lateral rearlower flap 42 extends to be located ahead of therear edge 63 of the frontlower flap 41. Thefront edge 75 is in the area of, or proximate, the transverse plane J, mentioned above, and can intersect the transverse planeJ. The edge 75 can also be provided to be rearward or forward of the transverse plane J, insofar as it remains forward of therear edge 63 of theflap 41. - The rear
upper flap 43 has arear zone 81 opposite afree edge 82, such rear zone and free edge being connected by alower edge 83 and anupper edge 84. Therear zone 81 extends within the area of the back of the lower leg of the user. The lateral rearupper flap 43 and medial rearupper flap 53 are co-extensive, i.e., continuous, in the area of thezone 81. Thefree edge 82 can be biased to tighten the upper 23. - The
lower edge 83 is closer to thesole assembly 22 than theupper edge 74 of the rearlower flap 42. For example, essentially, the distance that separates thesole assembly 22 from thelower edge 83 of the lateral rear upper flap is less than the distance between thesole assembly 22 and thelimit 78. - The
upper edge 84 is in the vicinity or in the area of theupper end 28 of theboot 21. - The arrangement of the lateral flaps 41, 42, 43 shown hereinabove provides the upper 23 with great bending freedom on the
lateral side 26. The same is true for themedial side 27, as will be understood hereinafter with reference toFIG. 5 . - Thus, by considering the
medial side 27, the frontlower flap 51 is shown to have afastening edge 91 opposite afree edge 92, theseedges rear edge 93 and afront edge 94. Thefastening edge 91 is affixed to thesole assembly 22 in a manner described above with reference to the lateral side. Thefree edge 62 can be biased to tighten the upper 23. - According to the first embodiment, the
rear edge 93 of the medial front lower flap is rearward of the transverse plane J, while remaining spaced apart from theheel 24. For example, the rear edge extends to be rearward by a value ranging between 1 and 50 mm with respect to the transverse plane J. In the same manner, thefront edge 94 is forward of the transverse plane J, while remaining spaced apart from thetip 25. For example, the front edge extends to be forward by a value ranging between 30 and 120 mm with respect to the transverse plane J. However, the distance between thefront edge 94 and thetip 25 is equal to or greater than 40 mm. Consequently, thefastening edge 91 measures between 30 and 140 mm, a value between 60 and 110 mm yielding good results. - The rear
lower flap 52 has afastening edge 101 opposite afree edge 102, theedges heel zone 103 and anupper edge 104 on the side of theheel 24, and by afront edge 105 on the side of the frontlower flap 51. Here again, thefastening edge 101 is affixed to thesole assembly 22. Thefree edge 102 can be biased to reversibly tighten the upper 23. - Essentially, the distance that separates the
sole assembly 22 from theupper edge 104 of the medial rearlower flap 52 is the same as the distance between thesole assembly 22 and thelimit 78. - The
heel zone 103 extends in the area of theheel 24. The lateral rearlower flap 42 and medial rearlower flap 52 are co-extensive, i.e., continuous, in the area of thiszone 103. In fact, theheel zones heel 24 with unity. - Finally, the
front edge 105 of the medial rear lower flap is located forward of therear edge 93 of the frontlower flap 51. Thefront edge 105 is in the area of, or proximate, the transverse plane J and can intersect the transverse plane J. Theedge 105 can also be rearward of or forward of the transverse plane J, insofar as it remains forward of therear edge 93 of theflap 51. - The rear
upper flap 53 has arear zone 111 opposite afree edge 112, such rear zone and free edge being connected by alower edge 113 and anupper edge 114. Therear zone 111 extends in the area of the back of the lower leg of the wearer. The lateral rearupper flap 43 and medial rearupper flap 53 are co-extensive, i.e., continuous, in the area of thiszone 111. In fact, therear zones heel 24. Thefree edge 112 can be biased to tighten the upper 23. - The
lower edge 113 is closer to thesole assembly 22 than theupper edge 104 of the rearlower flap 52. For example, essentially, the distance that separates thesole assembly 22 from thelower edge 113, of the medial rearupper flap 53, is less than the distance between thesole assembly 22 and thelimit 78. - The
upper edge 114 is in the vicinity or in the area of theupper end 28 of theboot 21. - The arrangement of the
medial flaps medial side 27. Overall, theboot 21 is flexionally free on the twosides - The bending ability can be appreciated by comparing
FIGS. 6 and 7 withFIGS. 4 and 2 , respectively. InFIG. 6 , theboot 21 is bent, or flexed, toward the front 25. The bending has caused the frontlower flaps lower flaps upper flaps lower flaps lower flaps upper flaps lateral side 26 ormedial side 27, respectively, without ever touching one another. As shown inFIG. 7 , the transverse cross section of theboot 21 is not modified, or is only very slightly modified by the bending in the area of the flexion crease. This means that in a transverse plane F that extends through the flexion crease, i.e., also through thelimit 78, and which forms, with thesole assembly 22, an angle α ranging between 30° and 60°, the transverse cross section of theboot 21 is stable. Consequently, no bulge is formed transversely as was the case for the prior art inFIG. 2 . - The transverse cross section, shown in
FIG. 7 , also corresponds to the boot in its natural non-biased state, as is the case inFIGS. 3 , 4, and 5. - Whether the
boot 21 is flexed or not, the rearlower flaps envelope 31. This improves comfort, as has been disclosed, but also facilitates the cooperation with theother flaps - To complete its structure, the
first envelope 31 includes aninner lining 121. The inner lining extends through the area of all of theflaps lower flaps front end 25. The flaps can be partially affixed to theenvelope 121, for example by means of an adhesive or stitching. Theinner lining 121 improves the cohesion of theenvelope 31 in the area of theflaps 41 to 43 and 51 to 53, and also forms the vamp of theboot 21, i.e., the front portion of the upper 23. The lining is structured so that the flaps remain free to move. Thus, the lining 121 is flexible. - Further regarding the completion of its structure, the
first envelope 31 includes atongue 122, which is positioned between thelateral flaps 41 to 43 andmedial flaps 51 to 53. - Thus, the
first envelope 31 includes sixflaps 41 to 43, 51 to 53, aninner lining 121, and atongue 122. - The
boot 21 also includes amechanism 125 for reversibly tightening thefirst envelope 31, which acts on the flaps as mentioned above. In a non-limiting manner thetightening mechanism 125 includes afront keeper 130,lateral keepers 131 to 136,medial keepers 141 to 146, alace 147 that runs through the keepers, and adevice 148 for reversibly blocking the lace. - More precisely, the
front keeper 130 is located on thelining 121, close to thetongue 122. Then, on thelateral side 26, the frontlower flap 41 has twokeepers lower flap 42 has onekeeper 133, and the rearupper flap 43 has threekeepers 134 to 136. In the same manner, on themedial side 27, the frontlower flap 51 has twokeepers lower flap 52 has onekeeper 143, and the rearupper flap 53 has threekeepers 144 to 146. - The distribution of the keepers is identical on the two
sides - The
blocking device 148 is not described in detail here, as it is well-known to those having ordinary skill in the art. Examples of a lace blocking device that can be used in a boot according to the invention are disclosed in U.S. Patent Application Publication Nos. 2006/01745516 and 2007/0169380, the disclosures of which are hereby incorporated by reference thereto in their entireties. Alternatively, it is possible to use a knot instead of thedevice 148. - In addition to the foregoing, as shown in
FIG. 7 , theboot 21 includes asecond envelope 151, structured and arranged to be inserted within thefirst envelope 31. In fact, theenvelope 151 is a slipper that improves comfort in the use of theboot 21. The use of a slipper is however not mandatory. - A second embodiment of a boot according to the invention is summarily shown hereinafter with reference to
FIG. 8 . Substantially the same reference numerals are used inFIG. 8 as used for the first embodiment, as the two embodiments differ only in terms of particular details of arrangement. - Thus, the second embodiment includes a
boot 21, having asole assembly 22 and upper 23. Thefirst envelope 31 includes, for thelateral side 26 andmedial side 27, respectively, a frontlower flap lower flap upper flap lower flap lower flap upper flap - The second embodiment is specific in that the front
lower flaps upper flaps inner surface 155 of the rearlower flap lower flap lower flap upper flap - In any case, the invention is embodied from materials and according to implementation techniques known to those of ordinary skill in the art.
- The invention is not limited to the particular embodiments described hereinabove and illustrated in the drawing, and it includes all of the technical equivalents that are within the scope of the claims that follow.
- In particular, although the
first envelope 31 includes exactly six flaps in the embodiments shown, it is possible, on one side, to reduce the number of flaps down to two, or to increase the number of flaps up to four, for example. - In addition, the invention illustratively disclosed herein suitably may be practiced in the absence of any element which is not specifically disclosed herein.
