Definitions

  • This invention relates to an adjustable fastening device for sport shoes, which comprises a rack mechanism for pulling two shoe upper portions one over the other and including a holder, a toothed element guided in said holder for sliding movement, one-way retainer means for making said toothed element fast with the holder in one of two sliding directions, and a lever having an operating portion pivoted on the holder, said lever being adapted to engage with said toothed element and drive it in the other sliding direction.
  • the fastening device of this invention is particularly, but not exclusively, suited for application to cyclist shoes to pull an instep portion of the shoe, also referred to as the strap, over the upper to thereby secure the cyclist's foot firmly within the shoe.
  • This prior fastening device has a fairly complicated construction which is liable to become jammed especially where the rack-and-pinion mechanism is fouled with mud or dirt.
  • the last-mentioned fastening device is particularly intended for motorcyclist boot applications, wherein the mass of the fastening device constitutes no problem.
  • the toothed element of the rack mechanism must have significant strength and hardness properties because, due to the path of movement of the lever in that mechanism, the working surface presented by the teeth to the lever tends to be small. It is for this reason that the toothed element is preferably made of a metal material.
  • the problem underlying this invention is to provide a fastening device which has such construction and performance characteristics as to overcome all of the drawbacks with which the cited prior art is beset.
  • a device as indicated being characterized in that said lever has a working portion which fits slidably on said operating portion and is urged elastically away therefrom.
  • a cyclist shoe comprising an upper 51 which includes an instep portion or strap 52 and a sole 53.
  • First and second fastening devices are provided between the instep portion 52 and the upper 51 for tightening the shoe 50 on the user's foot.
  • the second fastening device 55 consists of a pull fastener, known per se, which includes a strip 56a of a material known by its registered trade name of VELCRO(TM) is passed through a slot 56b, fixedly provided on the strap 52 and then bent over on itself.
  • a pull fastener known per se, which includes a strip 56a of a material known by its registered trade name of VELCRO(TM) is passed through a slot 56b, fixedly provided on the strap 52 and then bent over on itself.
  • the first fastening device comprises a rack mechanism having first and second fastening elements, respectively denoted by the reference numerals 60, 61, with the first mounted to the instep portion or strap 52 and the second to a corresponding side of the shoe upper.
  • the first fastening element has a small strap 62 formed with a serrated surface 63 over a major section and an opposed surface which is substantially flat.
  • an enlarged head 64 which projects upwardly from the plane of the surface 63.
  • the serrated section of said surface 63 is formed with a plurality of teeth 65 cut to a so-called sawtooth profile shape, i.e. having a face 66 substantially at right angles to the plane containing the surface 63 and a ramp-like sloping flank 67.
  • a respective straight track 68 Formed on either sides of the set of teeth 65 is a respective straight track 68 which is substantially flat.
  • the first fastening device 60 further comprises an anchor element 70 for the strap 62, at an adjustable location along the strap 52.
  • the anchor element 70 consists of a strip 71 which is made fast with the strap 52 as by gluing and/or sewing, and which is designed to distribute the fastening tension over a broad strap area and to distribute the pressure applied by the strap 62 when pulled tight over the tongue strap and the upper.
  • a bridging formation 72 having one or more openings 73 through which the strap 62 (which comes out of the bridge formation through a port 74) can be passed.
  • the working length of the latter can be varied which extends from the bridge formation 72.
  • the head 64 With the strap engaged in the anchor element 70, the head 64 will be received in the corresponding opening 73 substantially flush with the outer surface of the bridge formation 72.
  • the second fastening element comprises a holder 75 through which a single slotted hole 76 is formed, for attachment to the upper 51 (either by means of a screw or rivet, not shown), such that the holder can be set in position on the upper and easily removed for replacement.
  • a one-way retainer means consisting of a pawl 80 pivoted on a pivot pin 81 between the shoulders 76a,b is provided to enable the strap 62 to slide through the second fastening element in the direction of the arrow F in Figure 2 and to prevent it from sliding in the opposite direction.
  • the pawl 80 is biased by a spring 81 to mesh with the teeth 65 on the strap 62.
  • a lever 82 having an operating portion 83 and a working portion 84, is pivoted between the shoulders 76a,b about a pin 85, thus completing the rack mechanism of this fastening device.
  • the operating portion 83 comprises a flattened and enlarged portion, for convenient grasping by the cyclist, from where two parallel prongs 83a,b extend.
  • a blind hole 86 providing a socket for a coil spring 87.
  • Each prong is formed with a first hole 88, for passing the pin 85 therethrough, and a second, slotted hole 89 for loosely passing a second pin 90 therethrough which is driven into a corresponding hole 91 in the working portion 84.
  • Said working portion 84 is received and guided slidably between the prongs 83a,b and has a tooth formation 92, opposite from the hole 91, and a slotted hole 94 in which the pin 85 is received loosely.
  • each shoulder 76a,b On one side relatively to the two prongs 83a,b, is a socket 95 overlaid by a camming portion 96. Snap fitted into the sockets 95 are the corresponding ends of the pin 90 projecting from the prongs 83a,b, with the lever in the non-working position shown in Figure 5.
  • the portions 96 act on such ends of the pin 90 to urge the working portion 84 toward the operating portion 83 of the lever 82 during the transition from the position of Figure 4 to the position of Figure 5.
  • Attached to the shoe 1, on one side of the second fastening element, is preferably fixed a tapering shape fairing 97 effective to streamline the shoe and protect the second fastening element against incidental impact.
  • the second fastening device 55 is first tensioned manually, and the first device 54 is then set for fastening by passing the strap 62 through one of the openings 73 such that its serrated section 63 comes out through the port 74.
  • the running movement of the strap 62 is guided by the grooves 77.
  • the flank 67 of the teeth 65 will urge the pawl 80 to swing against the spring 81, thereby the strap 62 is allowed to run through the second fastening element 61.
  • the lever 82 is grasped via its operating portion 83 and raised in the direction of the arrow in Figure 3.
  • the ends of the pin 90 on leaving their respective sockets 95 and engaging with the profile of the portions 96, will urge the working portion 84 of the lever rearwards into the gap between the prongs 83a,b, against the bias force of the spring 87.
  • This provides, additionally to the above-noted function of retention of the lever 82 in the non-working position thereof, for the lever to be held close against the pawl 80, because the working portion 84 would be pulled toward the operating portion during the initial phase of the lever operation, when there may be interference with said pawl, thereby the second fastening element 61 can be made significantly compact.
  • the serrated section of the strap 62 can be prevented from being lifted within the holder 75 and causing seizure of the teeth 65 on the working end of the pawl 80 liable to interfere with the fastening device releasing.
  • the fastening device of this invention has proved its practical value in adjusting the fastening tension of cyclist shoes with one hand and without raising the feet off the pedals.
  • the structure is simple and reliable, easy to operate even by inexperienced persons.
  • the particular structure of the lever 82 prevents any damaging or wearing of the serrated section of the strap 62.
  • the strap may be formed from relatively soft materials, such as conventional plastics, which have significant flexibility.
  • the device can be readily replaced if damaged, and tends to self-align along the direction of the pull exerted on the strap.
