Definitions

  • the invention relates to a shoe intended for the practice of sliding sports, like the skate; such as inline skating or ice skating.
  • the invention relates to also a skate fitted with such a shoe.
  • the invention relates to the method assembly of a skate comprising such a shoe.
  • the inline skate typically comprises a plurality of aligned wheels held between a rigid frame connected to a more or less rising shoe.
  • shoe constructions There are many types of shoe constructions.
  • Traditional shoes derived from shoes Alpine ski, have a rigid plastic shell, possibly perforated, which grips the foot and the lower leg of the skater.
  • the inside of the shell is lined with a slipper padded for comfort.
  • This structure is not ideal because it tends to provide little flexibility, especially in the longitudinal direction; which hinders skating.
  • the structure is also considered too ⁇ hot ⁇ , bulky and relatively uncomfortable.
  • the shell is low and the liner partially fits into this as in document EP-A1-780,062.
  • the shoe consists of a relatively flexible, light and breathable upper part partially reinforced with a minimal heel and ankle support frame.
  • the frame is external and attached against a flexible rod forming part of traditional shoe. This is the case in particular in the US patent 5,437,466.
  • the framework is hidden by the rod; usually it is inserted between an external rod and a internal padding.
  • the shoe comes from traditional methods of shoe making using montage shape ⁇ mounting, as opposed to shoes made of an injected plastic shell.
  • One of the disadvantages of traditional shoes mounted on ⁇ form ⁇ is related to the forming the upper and mounting the upper with the sole.
  • stem parts to reinforce, in particular the heel and the toe of the shoe are inserted sheets thermoformable plastic hot deformed to give special curved shapes obtained in heel and toe.
  • ⁇ to bend ⁇ consist in shaping the stem with a hot punch and then a punch cooling which freezes a preform. Then place the preform of the rod in a template foot called ⁇ shape ⁇ for mounting the upper with an insole called sole ⁇ first assembly ⁇ .
  • the next steps are to assemble the sole to the upper; that is to say, to hot reactivate the preform, paste the edges of the rod, pull the edges of the upper using pliers, press the glued edges onto the insole and secure the mounting by staples or nails.
  • Such an assembly process is of course complicated and expensive and it requires significant know-how and investments in manpower qualified and in machines.
  • thermoformable plastic sheets can be replaced by rigid preformed inserts inserted between an external rod and padding. It's the case in particular in documents WO 95/15094 and WO 97/48458.
  • maintaining the rigid frame with the flexible rod part still requires the use of means of bonding of contact surfaces with each other. Bonding brings disadvantages when is to adhere flexible parts against rigid parts on surfaces important. It requires the use of materials compatible with the bonding between them. The bonding must withstand weather and external conditions such as humidity, temperature, the stresses of the relative flexion movements of the flexible parts by relation to rigid parts, and other constraints. The application of the flexible part must be done with great care to avoid the appearance of folds, air bubbles, unglued areas and other faults.
  • Bonding is generally a messy operation, most of the time harmful, for the manipulator and for his environment.
  • the applicant has proposed a solution through French patent application No. 9702139, not yet pre-published, which relates to a sports shoe, in particular intended for the practice of sliding sports teis that the roller skate.
  • the shoe has the structure of a flexible upper reinforced with a internal framework threaded, at least partially, in a part in the form of a cover.
  • the cover serves as a means of tensioning the frame part.
  • One such solution is simple, inexpensive and overcomes the problems of linking a flexible part on a part rigid.
  • the complex assembly problems of traditional shoes are also remedied and the use of special machines with high investment.
  • the flexible upper is extended by legs which are folded and fixed under the sole rigid outer of the shoe.
  • This can have drawbacks because this portion flexible lower part is at least partially visible on the outside. Indeed, this portion is more easily subject to abrasion, shocks, cuts and other aggressions than the other parts of the stem.
  • the edges of the skate serve as a sliding zone on various supports abrasives such as ramps, sidewalks or other urban obstacles.
  • a trend also consists to provide the detachable shoe relative to the chassis to meet a need wider use of skates in everyday life.
  • the use of shoe proposed in the aforementioned application is difficult to envisage in the cases of use cited for these reasons of durability, aesthetics, safety, etc.
  • the present invention relates to an improvement of the solution proposed in the French application No. 9702139, the entire content of which is incorporated herein by reference.
  • one of the objects of the invention is to provide a conciliatory shoe structure the advantages of a shoe structure as described in the above request referenced while providing more protection of the flexible rod part thus allowing a wider use of this type of shoe for the practice of sliding sports.
  • Another object of the invention is to propose the assembly of a shoe comprising a rod and an attached framework which is both solid, simple to produce and economic.
  • the solution therefore consists in providing a shoe intended for the practice of sports. glide which comprises a flexible rod provided with an outer covering portion and a cover-shaped portion.
  • the flexible rod is extended by at least a rim portion lower participating in the binding of the rod.
  • the shoe also includes a framework rigid internal having at least one part slid into the cover portion.
  • the frame is substantially complementary in shape to the cover-shaped portion so to serve as a support for tensioning the outer covering portion of the rod.
  • the shoe includes a sole base.
  • the shoe also includes in addition a portion of the insole, said first mounting sole, separated from said base sole and fastening elements connecting said lower rim portion of the upper and the framework against said portion of the insole.
  • the sole base covers, in at least part, said lower rim portion of the rod so as to protect the the lower part of the rod and in particular of the rim portion.
  • the invention achieves both the benefits of wrapping the rod under tension around the framework which serves as a support, while preserving good protection of part of the upper by an outer sole base.
  • the invention also relates to a skate which comprises a chassis connected to the shoe by removable fasteners; said fixing means connecting respectively, between them, the insole, the sole base and the chassis.
  • a skate which comprises a chassis connected to the shoe by removable fasteners; said fixing means connecting respectively, between them, the insole, the sole base and the chassis.
  • Such a method is particularly simple and economical. It does not require the use of sophisticated machine resources such as those previously indicated for the mounting on ⁇ form ⁇ of traditional shoes.
  • the sub-assembly thus assembled can be produced independently of the other elements making up the skate. It can thus be subcontracted or made separately.
  • Skate in line includes a shoe 2 attached to a chassis 3 on which is mounted a series of wheels 4 arranged in an aligned longitudinal configuration.
  • a braking device 5 can equip such a skate; in this case, it can be fixed on the rear part of the chassis, by example.
  • the shoe consists of a upper 20, a hidden internal framework 21 appearing in dotted line forming a support for holding the upper and an outer sole base 22.
  • the rod is mainly formed of outer covering portions made of flexible materials, foldable and partly at least breathable of the type used in sports shoes such as hiking. These materials can be chosen from textile materials natural or synthetic, leather, flexible plastics and others. However, the materials can be adapted according to the use of the shoe. In the case of the practice of snowboard, for example, the materials used will retain their flexibility but will chosen from warmer and relatively waterproof materials.
  • the stem is formed of lower portion of forefoot 23 which is extended upwards by a covering portion flexible riser 24 covering the ankle and part of the lower leg. The purpose of the rod to achieve wrap and comfort.
  • the rod has a longitudinal opening covered by a tongue 25.
  • Clamping means 26 formed, for example, of a lace and return elements, are provided to tighten the rod around the foot, the ankle and the bottom of leg. Other tightening means such as buckles, straps or other equivalent means can be adapted, as necessary, to different locations on the rod.
  • An element of reinforcement in point 27 is advantageously provided at the front of the rod. The element is formed relatively stiffer than the rest of the stem but thin enough to be connected to the rod by sewing or equivalent means. The purpose of this element is to provide lateral toe support and reinforcement of the toe in the event of compression or violent shock.
  • FIG. 2 illustrates in detail the internal construction of the shoe.
  • Frame 21 includes a heel support portion 28 which laterally and rearwardly wraps the heel of the foot to the level of the malleoli.
  • the framework extends towards the top of the rod by a collar portion 29 ensuring the lateral support of the ankle.
  • the collar portion has a substantially U-shaped open to the front to maintain the ankle laterally while preserving a certain freedom of bending in the forward direction. Necklace can go up more or less high above the ankle joint depending on the specific requirements of the disciplines practiced; some requiring less maintenance of the ankle to promote freedom of movement as for speed skating.
  • the collar portion is connected to the heel support portion integrally. The benefits are both technical and economical. Indeed, an integral framework brings more stiffness and support.
  • the framework 21 comprises reduction means section 30 connecting the heel support portion to the collar portion to allow the heel support portion to flex in at least one preferred direction relative to the ankle support portion.
  • reduction means section 30 connecting the heel support portion to the collar portion to allow the heel support portion to flex in at least one preferred direction relative to the ankle support portion.
  • the freedom of movement is directed in a substantially lateral direction due to the transverse arrangement of the foot relative to the gliding apparatus.
  • These means of reducing section are, for example, made of slots in the frame.
  • the invention could also provide a frame in several parts with a part of the collar articulated around a heel counter according to one or more articulations favoring a kinematics determined according to the destination of the shoe.
  • part of the framework 21 is threaded in a portion in the form of cover 31 of the rod.
  • This cover-shaped portion is delimited by the portion of external covering of the rod and by an internal flap 32 connected to the rod by means of connection such as a seam 33.
  • the flap is also formed of relatively flexible material.
  • a internal padding 34 such as open cell comfort foam completes the upper.
  • a padding envelope 35 is also connected to the upper by sewing, for example on the flap 34.
  • One of the advantages of the construction of the invention is also to provide a separation between at least part of the frame 21 and the padding 34 in order to preserve the integrity of the padding against abrasion caused by the framework, in particular, by the part superior of the framework, which is subjected to repeated relative movements in flexion of large amplitude.
  • the cover portion is interrupted approximately at the height of the limit between the heel counter portion and the collar portion while as shown Figure 3, the padding 34 and its envelope 35 extend to the level of the sole.
  • the flap therefore constitutes a separation from the part of the frame subjected to large flexion amplitudes. However, nothing also prevents the flap from extending all the way down sole level.
  • the cover portion 31 has a shape substantially complementary to the part of the framework in which it is threaded.
  • the upper edge of the frame must be in contact with the bottom of the cover portion for proper tensioning of the rod against the frame.
  • the cover portion keeps the collar in place and pre-positions it in its final configuration relative to the rod. It is therefore preferable that the portion of cover fits as closely as possible to the covered frame part.
  • the use of a cover portion has the advantage of facilitating the mounting of the frame on the rod without it is necessary to use means of connection between all the contact surfaces of the rod and the framework, such as glue or seams for example.
  • the rod extends downward by a portion of lower rim 36, just as the internal framework includes a portion of rigid rim 37. These two edges are sandwiched between the outer sole base 22 and a sole internal 38 known as ⁇ first assembly ⁇ .
  • Figure 3 also shows that a portion of padding 34 and its envelope 35 are interposed between the insert and the insole to ensure their connection.
  • fastening elements 39 preferably, mechanical anchors. These mechanical anchoring elements are chosen from among the nails, screws, seeds and staples.
  • the use of glue is in principle not necessary in the measure that the rod takes its shape by tension on the frame. Anchoring elements mechanical enough to keep the rod under tension giving it an aesthetic appearance smooth and clean and without appearance defects which may be due to the use of glue.
  • FIG. 4 shows the operation of mounting the frame 21 with the rod 20.
  • the cover-shaped portion 31 is threaded onto a preformed insert constituting the framework until the upper edge 40 of the insert reaches the bottom 41 of the cover portion.
  • the preformed reinforcing element 27 made of plastic is previously assembled and fixed, as by sewing, to the rest of the rod.
  • the next step is to assemble the upper on the inner sole 38 to form a sub-assembly 50.
  • the internal sole 38 is introduced, then a ⁇ shape ⁇ in the rod (not shown).
  • the ⁇ form ⁇ consists, as known in the clothing industry shoe, in a template having the general shape of the foot which takes place in the upper and serves anvil for fixing anchoring means called ists seeds ⁇ .
  • Figure 5 illustrates the upper comprising the inner sole 38 and the anchoring means 39 intended to be punched on the rim portion 36 of the rod.
  • the rim portion 36 of the rod forms a edge of continuous peripheral surface 40 which delimits a central opening 41.
  • This opening 41 is closed by the insole 38.
  • the outline of the sole protrudes the opening so as to form an overlap area serving as a support for the connection of the edge portion.
  • the rigid rim portion 37 is, for its part, interrupted in the frame shape limits. Additional anchoring means 42 connect the portion rim 36 to the insole on the side and forefoot.
  • the reinforcing element 27 forms a peripheral edge part so that it is rendered secured to the insole 38.
  • a sole base 22 is attached to the sub-assembly 50 thus formed.
  • the sole 22 covers the peripheral edge 40 of the upper so as to protect the connection of the upper with the insole.
  • the sole base can go up more or less high along the flexible covering portion of the rod.
  • the sole base advantageously comprises a side wall 48 forming an arch support extending at the rear by a rear wall 49 for protecting the heel.
  • fastening means 43, of the rivet or screw type ensures a connection of the periphery of the base sole, in particular at the forefoot, on the peripheral edge of the upper so as to prevent any detachment from the sole of the sole relative to the rest of the shoe.
  • the chassis 3 is then assembled to the shoe by removable fastening elements 50; preferably screw / nut systems, arranged substantially along a median longitudinal plane P of the shoe.
  • the elements are preferably the number of two longitudinally spaced so as to achieve a connection of the front and rear of the shoe on the chassis.
  • Fasteners respectively connect the inner sole 38, the outer sole base 22 and the chassis 3.
  • the fastening elements pass through holes 44, 45 of the insole and holes 46, 47 of the sole base.
  • at least one of the holes of each part consists of an oblong slot 45, 47; in this case the hole front, oriented longitudinally.
  • These holes 45, 47 cooperate with an oblong hole (not shown) oriented transversely to the median plane P allowing fine adjustment of the angular position of the shoe relative to the chassis around a fixed point formed by the other holes 44, 46; in this case the rear holes in the example shown.
  • the holes rear could also have an oblong light shape in order to increase the freedom of adjustment of the shoe relative to the chassis.
  • the connection of the chassis by fastening elements in direct engagement with the insole 38 has many advantages. Among them, that of ensuring securing the connection of the upper and the insert on the insole; these parts being compressed during tightening on the chassis. Likewise, that of being able to keep a base of independent sole on which the edges of the upper are not directly stretched and connected gives more freedom of construction of the sole base.
  • the sole base can be manufactured in a wide range of hardnesses and based on very diverse materials. Through example, for ⁇ aggressive ⁇ skating, the sole base can be chosen by very rigid and abrasion resistant materials. For a removable shoe skate, the base of sole can be made of softer rubber suitable for walking. For skating recreational, the sole of the sole can be a compromise between these two extremes.
