Definitions

  • the present invention relates generally to the field of footwear and in particular relates to a retractable antislip device for footwear.
  • US 3717238 discloses a retractable antislip device for skiboots and similar articles of footwear comprising a casing embedded in the sole or heel of the shoe and a longitudinal rotatable camming member mounted therein over a longitudinal plate provided with depending spurs accessible through openings in the bottom wall of the casing and extensible downwardly from the bottom plane of the sole or heel.
  • the plate member is biased upwardly by springs to retract the spurs.
  • the rotatable camming member has a radial handle element at its end which is accessible by the user for manually operating the cam.
  • this device is so structured as to be unfeasible its embedding within a sole or heel of limited thickness such as the every day shoes.
  • the invention consists in an universal retractable device, with an anti-slip function, placed in the thickness of the sole and more specifically in the heel's portion and/or the front portion of the sole.
  • the device comprises a toothed bar housed in a corresponding groove formed in the sole and movable through the groove from a first position in which it is completely retracted in the sole to a second position in which it protrudes therefrom, and actuating means for moving the toothed bar from the first to the second position and vice versa, manually operable by an user.
  • the actuating means comprise a sliding member integral to the toothed bar movable within the sole in a direction substantially perpendicular to the lying plane of the sole and a shaft pivotally housed in the sole perpendicularly to the sliding member.
  • the shaft has an outer end formed with means for rotating the shaft around its axis and is connected to the sliding member in such a way that a rotation of the shaft in either direction corresponds to a movement of the sliding member and the toothed bar integral therewith from the first to the second position and vice versa.
  • the device is preferably placed in the heel and in the front portion of the sole of the footwear through seats shaped on purpose to receive it with the sides perfectly sticking to the mechanism.
  • the device is simple and structured to be put in all thicknesses of the sole with all kinds of materials both with a smooth profile and/or wrinkled on the sole's surface in contact with the ground.
  • the device is embedded in the sole at the sole manufacturing step, on the inner part, irremovably integral with it.
  • the device used gives the footwear the possibility to be used in two ways:
  • the anti-slip function is started by protruding a toothed bar from the heel and/or from the front portion of the sole which, forced by a movement perpendicular to the sole/heel surface and preferably guided by its sides, allows the teeth distributed on the whole surface of the bar, to get a grip on the ground.
  • the device is particularly light (reduced number of parts); its dimensions do not modify the shape and design of the footwear and do not make the shoe heavy with the use of thicker soles.
  • 1 schematically denotes a sole portion, namely the heel portion, of a shoe in a bottom plan view.
  • An arc-shaped groove 2 extending substantially perpendicularly to the longitudinal axis of the shoe indicated at Y-Y in figure 1 is formed on the bottom surface of the heel 1.
  • a correspondingly shaped bar 3 is placed in groove 2 and is slidable in a substantially perpendicular direction to the lying plane of the sole or to the heel surface.
  • Bar 3 is integrally connected to a piston 4 slidingly engaged in a seat 5 formed at an intermediate point of groove 2 in the heel portion and perpendicular thereto.
  • a perimetrical slot 6 is formed on the lateral surface of piston 4 and a pin 7 is engaged in slot 6 and is slidable circumferentially along it.
  • Pin 7 extends eccentrically from an inner end of a shaft 8 pivotally housed in a seat 9 extending perpendicularly to piston 4 and radially from an edge 1a of heel 1. In this way the outer end of shaft 8 is accessible to the user to angularly displace shaft 8 around its longitudinal axis.
  • a portion 8a of reduced diameter is formed at an intermediate point thereof and a pin 10 is forcibly engaged therewith perpendicularly to the surface of the heel.
  • the outer end of shaft 8 is provided with a manually operable diametrical rib 11 through which the shaft can be rotated angularly in either direction by 180°.
  • the rotation of shaft 8 causes pin 7 to move according to a circular trajectory coaxial to the longitudinal axis of shaft 8 and, consequently, piston 4 to move in the seat 6 in the axial direction thereof.
  • toothed projections 12 extend from the face of the bar 3 opposite to piston 4.
  • toothed projections 12 consist of nine teeth.
  • the movement of piston 4 in a first axial direction causes the toothed projections 12 to protrude from the bottom surface of the heel to provide a grasping action on a slippery ground, while the movement of piston 4 in a second, opposite axial direction causes the toothed projections 12 to retract within groove 2 to avoid any unnecessary hindrance to the user movements.
  • the end-stroke positions of pin 7 lie on an axial plane with respect to piston 4, whereby an axial force acting perpendicularly on pin 7 when the toothed projections 12 are in their protruded position does not cause a rotation of shaft 8 that would result in an unwanted retraction of the toothed projections.
  • An O-ring 13 is placed in a circumferential groove 14 formed on the shaft 8 to ensure a proper sealing.
  • the arc-shaped form of toothed bar 3 has proven to be the most effective for the heel portion of a shoe sole because the user weight is better distributed evenly on the heel's surface and help walking with less effort. Thanks to the arc-shaped form, back swing problems occurring when grasp points are placed on a straight line perpendicular to the sole longitudinal axis are prevented.
  • a diametrical notch can be (not shown) formed to rotate the shaft by engaging a metallic coin therein.
  • Toothed bar 3' is slidably arranged in a linear groove 2' as shown in figures 5 to 8. More than one toothed bar 3' and 3" , placed in corresponding linear grooves 2' and 2", can be also provided as shown in figures 9 to 11.
  • the single or double toothed bar 3' and 3" are moved in a direction perpendicular to the sole surface by piston 4, to which they are integral, and piston 4 is moved axially by rotation of shaft 4 exactly in the same way as described above for the arc-shaped toothed bar.
  • a shoe sole is preferably provided with both types of retractable toothed bar, i.e. the arc-shaped toothed bar in the heel portion and at least one linear toothed bar in the front portion of the sole.
  • the means for moving piston 4 axially i.e. shaft 8 with eccentric pin 7 and actuating rib or notch 11, can be arranged in any radial position with respect to piston 4 as shown in dotted lines in figures 1, 5 and 8 according to functional and design needs.
