Definitions

  • the present invention relates to a loop / blocker for a lace or the like intended more particularly when lacing a shoe.
  • a shoe is traditionally made up of a sole and a upper provided with a opening for the passage of the foot and comprising on either side of this opening a set of loops for one or more laces intended to allow the closure of this opening when traction is exerted on them.
  • loops are generally formed by hooks, but these hooks do not retain not the lace when it is loose, or loops through which pass the laces, these passing alternately above and below the plane of each loop.
  • a major problem with all known loop systems is the high friction occurring between the lace and its loop, so that the simple pull on the ends free of the lace is not enough to obtain an effective tightening over the entire length of the lacing and that you must exert traction on each strand of lace between two loops to obtain a efficient and uniform tightening over the entire lacing area, including at the end of the foot.
  • This problem is particularly crucial for shoes made of relatively material rigid, for example thick leather mountain shoes or skating shoes, having a relatively rigid plastic shell, for which effective clamping is sought up to the end of the foot.
  • the friction or poor sliding of the lace is to a certain extent necessary because the resulting braking effect also serves as a non-return facilitating tightening, and in particular the formation of the loop or end node.
  • WO 96/24269 discloses a lace loop / blocker system consisting of a ring movable relative to a body which, depending on the position it occupies relative to the body, allows the sliding of a lace or on the contrary serves as a blocker of said lace.
  • Such a pass / blocker certainly has advantages but also disadvantages, and including an expensive multi-room and multi-material structure.
  • the yield of such a system in its operating mode as a passer-by is not optimum since the lace passes alternately on either side of the lacing plane, hence friction parasites.
  • Document US Pat. No. 4,290,173 relates to a device for blocking the tension of a lace having a sliding channel for tensioning the lace and a frustoconical space to lock the lace.
  • the canal and the space are part of plans angularly distinct; which increases the risk of yaw jamming when tension and promotes loss of yaw performance.
  • the object of the present invention is to remedy the drawbacks of the state of the art and to provide an improved pass / blocker, which is costly and bulky minimum, and which makes it possible to reconcile the two conflicting requirements to improve the tightening performance, and to offer a jamming function at the end of tightening.
  • wedging part is in continuity with the sliding part provides an immediate wedging effect after the tightening operation properly, that is to say that where a tensile force is exerted on the strands of the lace, as soon as said strands are brought back transversely to the direction of traction to form the knot.
  • the sliding part and the wedging part are substantially coplanar, and the median plane of the sliding part and the part of wedging is substantially coplanar with the lacing plane. Therefore an optimal yield of the tightening is guaranteed since the lace always remains substantially in the same lacing plane and that friction is thus reduced to the maximum.
  • Figures 1 and 2 illustrate the operation of a passer / blocker 10 according to the invention disposed at the upper end of a lacing zone 9 of a shoe 1, which zone of lacing 9 comprises a plurality of loops 8 arranged on either side of an opening 6 of the shoe, and through which a lace passes 7.
  • the passer / blocker 10 is first consisting of a lug 11 for attachment to the shoe allowing both a connection by sewing than by rivet. Of course any other method of attachment to the shoe can also be expected.
  • the functional part of the pass / blocker 10 consists essentially of two parts, namely a first part 20 of sliding and a second part 30 of jamming.
  • the sliding part 20 essentially consists of a housing essentially cylindrical, the diameter of which is slightly greater than that of the lace in front slide in the loop 10, and which defines for said lace a passage path 21 oriented in a direction "T" corresponding to the pulling direction of the lace (cf. arrows "T” on the Figures 1 and 3), and oriented substantially parallel to the general direction of the area of lacing 9.
  • This passageway 21 is defined laterally by an outer wall 22 substantially curvilinear in transverse direction, but extending substantially parallel to the direction tensile "T" in the longitudinal direction, and by an internal wall 23, that is to say located from side of the lacing area, of substantially curvilinear shape in the longitudinal direction and comprising two entry and exit radii 24, 25 respectively. It is also defined in top and bottom by two walls respectively 26, 27, rounded.
  • the path 21 thus defined allows, by its rounded parts and its orientation general, optimum sliding of the lace. Furthermore, this passage path 21 defines a path of the lace, whose median plane is always located in the same plane "P", which is that of lacing, without passage on one side and the other of this plane. This results in a further sliding improved lace, and therefore optimum tightening efficiency due to the elimination of Parasitic friction, linked to the passage of the lace on either side of the lacing plane, typical of conventional passers-by systems.
  • the wedging part 30 is located in the extension of the sliding part 20, at the outlet end of said sliding portion 20 and its median plane is coincides with the median plane "P" of said sliding part, and is oriented according to a direction "B" substantially perpendicular (ie making an angle "a” between substantially 45 ° and 90 °) to the direction of traction "T", and corresponding to the direction of blocking.
  • This wedging part 30 is defined, on the side of the lacing zone, by a wall cylindrical 31 extending from the wall 25 of the sliding part 20, and high and low by two substantially horizontal walls respectively 32, 33.
  • the part 30 is not closed, on the side opposite to the lacing zone, so as to allow the drawdown of the lace 7, from its sliding position shown in phantom according to the direction "T" in FIG. 3.
  • the two walls 32 and 33 are set back from the adjacent walls 26, 27, of the sliding part 20 and thus delimit a passage section with a height "h” significantly reduced compared to the height "H” of the passage section of road 21 (cf. figure 4).
  • the "h / H" ratio is between approximately 0.3 and 1.
  • the walls 32, 33 are also provided with teeth 34.
  • teeth are preferably inclined, at an angle "a" of about 45 ° relative to the locking direction "B" shown in figure 3.
  • teeth could also be straight and for example parallel to the direction of the wall 22.
  • Each tooth 34 comprises, in the direction of the blocking direction "B", a first part 34a in the form of an ascending ramp and a second part 34b relatively straight so as to facilitate, by the ramp effect, the jamming of the lace, and to retain, by the wall effect of their part right 34b, said lace in the wedging position.
  • each tooth 34 also comprises a profile 34c in the form of a ramp flaring from the bottom 31 of the wedging part 30 up to the free ends thereof, forming with the wall 32, 33, an angle " ⁇ ", between approximately 0 and 15 °, and preferably approximately 6 °, so as to provide a additional jamming.
  • the passer / blocker 10 according to the invention is very simple and easy to use.
  • the realization of the knot is greatly facilitated since it can be carried out on strands released from any tension, due to the blocking effect obtained.
  • this pass / blocker is particularly simple and easy to use since the movements necessary for the traction or blocking effect correspond exactly to those that are naturally effected.
  • the blocking does not impose to fold the lace in a lower plane as it is the case in the pass / blocker of WO 96/24269, (US.A.5852857) and is therefore much more practical to use.
  • Such a pass / blocker can be produced very easily since it does not include any piece movable in one piece by molding of a suitable plastic material, and is therefore inexpensive to make.
