Definitions

  • the present invention relates to a sports shoe intended for sports such as inline skating, ice skating, cross-country skiing, hiking, snowboarding, wake board, etc.
  • sports such as inline skating, ice skating, cross-country skiing, hiking, snowboarding, wake board, etc.
  • the proposed shoes combine rigid parts to provide protection and transmission functions for efforts, and softer parts for comfort, ventilation, etc.
  • a shoe that meets the specificities of the practice of “aggressive” skate can therefore advantageously present a collar covering a part of the lower leg which is connected to a rigid shell base covering, at least partially, foot. More flexible parts are generally associated to rigid parts, such as internal padding taking place inside the hull. To ensure this need for transverse laxity, the collar is connected to the shell base according to two systems of substantially transverse axes of each side of the shoe associated with tilt means transverse, such as lights facilitating movement transverse relative of the collar relative to the shell base.
  • the connecting means, proper of the collar on the basis of shell advantageously include removable means of the screw / nut type.
  • Such means have the advantage of resist the significant pullout forces imposed on the collar during bending. For this, the thread length, the diameter of the shaft rod, etc., must be dimensioned Consequently.
  • There are other ways of fixing but not entirely satisfactory such as rivets which are much less resistant to tearing.
  • Way to fixing screw / nut also has the advantage of making the interchangeable collar. Indeed, the trend is towards "Customization" of products.
  • Another problem is related to the difficulty of controlling the intensity of the tightening while retaining possibilities of relative movements between the collar and the shell. Indeed, if the tightening is too strong, there is a risk of making the shell base collar with no possibility of movement. Yes the tightening is too loose, the risk of loosening is greatly increased. It is therefore antagonistic to want to secure a tightening without risk of loosening and times allow a certain play for the sliding of the pieces to tighten.
  • the present invention therefore aims to provide a solution to the above problems.
  • Such a design of the connecting means makes it possible to prevent loosening of the screw element caused by movements repeated of the collar with respect to the shell base. On the other hand, the possibility then exists of voluntarily provoking the loosening by forcing until deformation or rupture of the lip portion by applying a couple of loosening beyond a predetermined threshold.
  • Another advantage is that it is not necessary applying too much tightening torque to secure the fixing, and therefore, the movement between the pieces continues to be favored regardless of the intensity of the tightening.
  • the invention is illustrated in the context of an inline skate 1 of the “aggressive” type illustrated in FIG. 1 to the extent where, as far as the applicant is aware, this is the method of preferred embodiment in which the invention presents the most recognized benefits.
  • the invention cannot be limit to this type of application only but can cover other types of products incorporating a technical shoe provided with rigid parts assembled together and in which the rigid parts are intended to move relatively to each other when stressed leg or foot.
  • the inline skate of FIG. 1 comprises a shoe 2 attached to a chassis 3 fitted with a series of wheels 4 oriented in a longitudinal alignment.
  • Chassis 3 comprises lateral flanges 30, 31 interconnected by bridges 32, 33 located respectively at the front and at the rear of the shoe. Bridges have portions extending laterally beyond the side flanges on either side of these, so as to provide sufficient bearing surfaces with the sole 20 of the shoe with which they come together.
  • the assembly of the chassis on the shoe can be use any suitable fixing means such as screws, rivets, gluing, welding, interlocking or any combination appropriate of these means.
  • the shoe part comprises a shell base 5, in hard plastic for example which forms a rigid part of the shoe at least partially covering the foot.
  • the region covered by the shell base 5 can be variable depending on the type of shoe use.
  • the hull base In the context of a skate of the "aggressive" type, the hull base is generally quite extended for reasons of protection and support of the foot. It extends substantially continuously from the region of toes 50 to the rear heel counter 51.
  • the base of shell can go up more or less high compared to the region malleoli as appropriate.
  • An opening 52 is generally provided on the top of the foot on the edges of which clamping means of the passers-by type 53 or other, are provided to tighten the volume of the shell base.
  • part of the shell base could be formed of a flexible material such as a textile or the like, of course without departing from the scope of the invention.
  • the hull base is extended upwards towards the leg by a collar 6, also comprising, at least, relatively rigid portions intended to ensure grips support and lower leg protection.
  • It can be a relatively rigid plastic part having a general shape tubular open towards the front including a cover adjustable to clamping by at least one clamping means 7 of the type loop, for example.
  • the collar has a support region rear 60 offering a wide and comfortable support part to the base of calf during rear support.
  • the collar 6 relates to the shell base by partial covering of a lower portion of the collar on a upper portion of the shell base approximately in the malleoli region.
  • the main anchoring of the collar on the hull base is produced by connecting means 8 located each side of the shoe.
  • the shoe also has other elements such as an internal soft padded liner 40, for example, essential for the comfort of the foot.
  • Figure 1 shows one of the connecting means on the outside. It is necessary realize that another connection means is located opposite the interior side.
  • the necklace is assembled in two lateral connection means favoring flexibility front / back of the lower leg.
  • the front / rear flexibility is controlled forwards and backwards by means of elastic return 9 consisting of a rear hoop 61 of the collar and a rear opening 62 separating the arch from the rear support part 60 of the collar.
  • the base of the roll bar 610 is able to deform elastically to favor a substantially rotational movement of the collar in a forward / backward direction.
  • a rear stop means 10 is provided in order to stop the movement of the collar, more specifically of the arch 61, relative to the hull base.
  • the arch 61 has a lower edge 611 bearing on an edge upper 510 of the heel counter.
  • the arch 61 is fixed to the shell base by means of appropriate fastening element 11.
  • screw type means preferably self-tapping screws engaged directly in the material of the hull base or in independent elements.
  • the fastening means 11 can be omitted so as to release the bending from back to front, thus promoting skating movement.
  • the roll bar plays the role of elastic return means by deformation when pressed back to a return to the rest position.
  • connection means 8 will now be described from in more detail based on the predefined construction it being understood that this building base is not the only one possible and that the connecting means can be adapted to other types of constructions such as "base of shell / collar "or others.
  • Figure 2 shows the detail of a connecting means 8 of the collar 6 on the shell base 5.
  • the shell base is provided with a circular hole 54 of axis I extending transversely.
  • the collar is, in turn, provided with an oblong lumen 63, preferably oriented substantially vertically.
  • the connecting means 8, proper comprises a screw element 80 and a complementary nut element 81 which assembles the collar on the shell base through the hole 54 and the oblong opening 63.
  • the light 63 promotes a relative movement of the collar relative to the shell base in the main direction of orientation I 1 of the light. In this configuration, it is understood that the connection promotes forward / backward movement but also transverse or lateral movement of the collar relative to the shell base.
  • the connecting means 8 is therefore a partial connecting means in the sense that it must maintain the junction of the rigid parts 5, 6 with one another while allowing a degree of freedom in one or more given preferred directions; the relative displacement operating by sliding of the contact surfaces of the parts 5, 6 between them.
  • the light is formed on the shell base while the hole 54 is formed in the necklace.
  • the screw member 80 includes a head 800 extending by a rod portion 801 comprising a threaded portion 802.
  • the head 800 is supported on the edges of the outer surface 630 of the collar.
  • Head 800 is provided with a key imprint, of the awl type, for example.
  • the nut element 81 comprises, for its part, a head 810 in press on the edges of the internal surface 540 of the base of shell. It is also provided with a tubular portion 811 comprising an internal threaded surface 812 and an external surface 815 of diameter corresponding substantially to the diameter of hole 54 in which it undertakes.
  • the external annular surface 815 is the means for guiding the axis formed by the means for connecting to the times in hole 54 and in oblong lumen 63.
  • the part of threaded rod 801 cooperates in screwing with the portion 811 threaded tubular so as to bring the shell base closer to the collar while leaving a functional play which allows a relative sliding movement of the shoe parts between them; in particular, in this case, according to the direction defined by oblong.
  • the stem portion 801 includes an opposite end portion 803 at the head 800 of the screw element. This end is formed with a portion of lip 804 which is protruding overflowing radially beyond the section of the internal threaded surface 812 to secure the screw element in the direction of the axis of engagement I of the connecting means.
  • the element nut has a well 813 opening to the outside, the section is preferably that of a key fingerprint, for example of the awl type. Inward, the well is connects to the internal threaded surface 812 by an edge 814 annular shoulder against which the lip portion is supported.
  • Figure 3 illustrates the method of assembling the collar 6 on the hull base 5.
  • the element nut 81 is pre-engaged through hole 54.
  • the element of screw 80 is then attached and screwed with the nut element 81 until an appropriate tightening level is reached which ensures both sufficient mechanical strength depending on the thread length while leaving sufficient clearance between parts 5, 6 in order to authorize their relative displacement by slip.
  • a bolting adapted to this operation including a punch 90 provided with a concave annular imprint 91.
  • the imprint must have a section smaller than the section of well 813 of the nut element in order to reach the end to be bolted.
  • the end of the screw element includes a portion straight tubular.
  • This portion is deformed by the action of punch so as to form a portion of continuous lip annular which projects radially and bears on the edge 814 from the nut element well.
  • the tool has the opposite a bearing surface 92 for supporting the head of the element of screw 80 during the operation.
  • Figure 5 shows the disassembly operation of the means of connection by two keys 93, 94 engaging the fingerprints 805, 813 formed in the heads of elements 80, 81.
  • a certain predetermined loosening torque threshold it is possible to remove the rolling or by deformation elasticity of the lip portion, either by rupture of the portion of lip under the applied torque force.
  • disassembly can be destructive in the sense that element 80 may be damaged in some cases of lip rupture.
  • the screw element is replaced by a new one.
  • element and assembly is carried out according to the method described previously.
  • the disassembly is a facilitated operation which only employs traditional keys and applying a sufficient couple of loosening.
