Definitions

  • This invention relates to a fastening device for sport shoes, in particular for cross-country motorcycling boots, being of a type which comprises first and second fastening members releasably engageable with each other to hold corresponding parts of the shoe upper clasped together.
  • the fastening arrangement of this invention is specially designed for application to cross-country motorcycling boots, the term also encompassing motorcycling boots for off-road use.
  • a first type fastening device is lever operated, it including a toothed lever pivoted on a small base which is in turn attached to one of the upper portions to be clasped together and cooperating with a ring attached to the other portion of the upper. By engaging the ring with selected teeth and turning down the lever, the fastening tension can be adjusted.
  • the second type includes pull-away fastening arrangements, as implemented by a material known in the trade under the trademark of "VELCRO".
  • a typical drawback of the lever-operated fastening arrangements is that, in order to vary the fastening tension after closing the boot, the fastening arrangement must be fully relaxed to allow the ring to be moved into engagement with a different lever tooth.
  • Pull-away fastening arrangements are instead easier to adjust, although they have difficulty to allow of relatively high fastening tension forces.
  • this second fastening arrangement type holding power is apt to deteriorate when the material from which it is formed (VELCRO) becomes fouled with dirt or mud.
  • the problem that underlies this invention is to provide a fastening device having such construction and performance features as to solve all of the problems with which the cited prior art is beset.
  • a device as indicated being characterized in that the first fastening member comprises a guide and the second fastening member comprises a slider arranged to be slidable along said guide and being held in releasable engagement therewith, between the guide and the slider a one-way stop means being provided to releasably lock the slider to the guide in either sliding direction.
  • the reference numeral 1 generally denotes a cross-country motorcycling boot according to this invention.
  • the boot 1 comprises an upper 2 and a sole 3. A portion of the upper defines a bootleg 4 which is not fully closed to itself. To close the bootleg 4, three fastening devices, each indicated at 10, are provided.
  • a guard 5 Adjacent to that fastening device 10 which lies closest to the sole 3 is a guard 5 attached to the upper 2 as by means of rivets 6.
  • Each fastening device 10 comprises first and second fastening members, respectively indicated at 11 and 12.
  • the first member 11 comprises a guide 13 which extends mainly along the longitudinal direction and has a substantially T-like section profile with a web 14 and a flange 15.
  • the web 14 is formed with a longitudinal groove 19.
  • the guide 13 is removably mounted in an adjustable manner to a small base 18 by means of screws 17 passed through holes 20.
  • the base 18 has a bead formation 19 which fits in the groove 16.
  • Said base 18 is provided with a plurality of holes 21 set at pitch distances apart (two pairs of such holes are shown in Figure 2) and adapted to receive the screws 17 to thereby enable the guide 13 to be adjusted in position on the base.
  • the second fastening member comprises a slider 25 having a longitudinal groove 26 for receiving the guide 13.
  • a bracket 28 is connected to one end of the slider 25 in a swinging fashion for securing the slider 25 on a corresponding portion of the boot 1 upper.
  • the bracket 28 has two holes 29 into each of which a plastics button 30 fits removably by snap action, thereby by pulling the buttons 30 out of their respective holes 29, the second fastening member can be removed from the boot and, for instance, replaced if damaged.
  • a housing 32 for a corresponding pawl 33 is formed at the remote end of the slider 25 from the bracket 28, on either sides of said slider.
  • each housing 32 is apertured to let an end 34 of the corresponding pawl 33 project into the groove 26.
  • a spring 35 is arranged between the slider 25 and each pawl 33 to urge the latter into a working condition with the end 34 projected into the groove 26.
  • An operation lug 37 is formed at the opposite end of each pawl 33 to move it manually to a rest position against the bias of the spring 35.
  • the end 34 of the pawls 33 is tooth-shaped with a flank 38 arranged to engage the teeth 22 on the corresponding toothed surface of the web 14, thereby to provide a one-way stop means effective to prevent the slider 25 from sliding along the guide 13 in either of the two longitudinal directions, and having an inclined apical surface 39.
  • the surface 39 forms a ramp adapted to cooperate with the corresponding longitudinal edges of the flange 15, with the slider 25 forcibly abutting the guide 13, thereby the pawls 33 are spread apart to the rest position and enabled to move over the flange 25 and engage in the corresponding toothed surface of the web 14.
  • a flat top surface of the tooth-shaped end 34 defines a shoe-like retainer 40 slidable over the bottom surface of the flange 15, which functions thus as a slideway 41, to hold the slider 25 in engagement with the guide 33 once the fastening members 11, 12 have been coupled together.
  • a lever 43 is supported pivotally on the slider 25 by a pivot pin 44, at a seat 46 in which the lever 43 can be tucked away.
  • a spring 47 acts on the lever 43 to urge it into the the seat 46.
  • the lever 43 has a free end 48 adapted to cooperate with the notches 23 to provide a rack mechanism for shifting the slider 25 along the guide 13 in the direction allowed by the one-way stop means.
  • each fastening device 10 To fasten the boot 1 on, after it has been put on, the slider 25 of each fastening device 10 is pushed against its respective guide 13 so as to engage the pawls 33 with the web 14 as previously described.
  • the user is to raise the lever 43 and bring its end 48 to engage in one of the notches 23.
  • the engaged notch 23 will act as a pivot for the lever 43, thereby the slider 25 is driven forward by a short distance with an amplified force by the arm of said lever.
  • the operation may be repeated until the required fastening tension is achieved.
  • the pawls 33 are caused to swing by reason of the inclination of the teeth 22 on the toothed surface. A backward movement of the slider 25 along the guide 13 would be inhibited by the flank 38 of each pawl becoming engaged with the teeth 22.
  • Figures 7 to 11 show a modified embodiment of the device described so far, which affects the second fastening member, generally indicated at 100.
  • the fastening member 100 also comprises a slide 25 whose surface facing the first member 11, in use, is formed with a longitudinal groove 26 for accommodating the guide 13 therein, as in the previous embodiment.
  • the lever configuration which is generally designated by the reference numeral 101 in this variation.
  • the lever 101 comprises an operation portion 102 and a working portion 103 which is guided slidably on the operation portion and retractable thereinto against the bias force of a spring 104.
  • the operation portion 101 is journalled at one of its ends on the slider 25 about a pin 105 passed with some radial clearance through holes 106 and is tucked away, in a non-operational position shown in Figure 10, into the seat 46 on the slider 25.
  • the working portion 103 is slidable within a recess 107 provided on the operation portion at the end attached to the slider 25.
  • the recess 107 causes two parallel prongs 108 to be formed on the lever portion 102, each of which prongs has, besides the corresponding hole 106 for the pin 105, a slotted hole 110 extending along the sliding direction (arrow A in Figure 9) of the working portion 103.
  • a peg 111 is captive across the working portion 103 so as to project sideways thereform and loosely engage in corresponding slotted holes 110; in a corresponding way, a slotted hole 112 is provided transversely through the working portion 103 wherein the pin 105 is loosely received to hold the working portion 103 guided on the operation portion 102.
  • a tooth 115 which has a ramp-like back surface 116 and is arranged to cooperate with a lip 118 formed in the seat 46 on the slider 25 so as to hold releasably by snap action the lever 101 in the non-operational position shown in Figure 10.
  • the tooth 115 will cause, by interfering with the lip 118, the working portion 103 to move backwards against the bias from the spring 104 past the lip 118.
  • the tooth 115 will engage in a corresponding notch 23 on the guide 13. Accordingly, in turning the lever 101, as the distance of the pivot axis provided by the pin 105 from the bottom of the notch 23 engaged by the tooth 115 decreases (due to the slider 25 being moved forward on the guide 13), a backward movement of the working portion 103 into the recess 107 is brought about which is resisted elastically by the action of the spring 104.
  • This feature enables the length of the lever 101 to be adapted continuously to the distance of the pin 105 from the engaged notch 23, thereby the tooth 115 can be fully and effectively engaged with its corresponding notch at any stage of the lever pivotal movement without simultaneously causing the tooth to interfere with the notch bottom as the distance between said bottom and the pin 105 decreases.
  • both the lever 101 and the guide 13 may be formed from plastics with no loss in strength and reliability of the fastening device.
  • the lever 101 will be moved back toward the non-operational position shown in Figure 10.
  • the working portion 103 will be moved with the tooth 115 past the lip 118, being initially moved backwards on the operation portion on account of the ramp-like configuration of the back 116, thereby the lever 101 can be tucked away into the seat 46 and held stably therein.
  • a major advantage afforded by the fastening device of this invention is that the effectiveness of the device is unimpaired by the presence of mud, water, or dirt, which makes this device particularly suitable for off-road motorcycling footwear.
  • the fastening device just described allows a significantly accurate adjustment of the fastening tension without requiring disengagement of the first and second members from each other. Thanks to the latter feature, the fastening tension may be adjusted while running with one hand.
  • the provision of a guard over the closest binder to the boot sole effectively reduces the likelihood of damaging the corresponding slider, especially when the foot is brought to contact the ground while the vehicle is running.
  • any damaged fastening devices can be readily replaced by virtue of the arrangement provided for connecting the second fastening member to the boot upper.
