Definitions

  • the present disclosure relates to an anti-slip unit for providing an anti-slip function for shoes, and functional shoes including the anti-slip unit.
  • Shoes are originally aimed at protecting feet from external impacts or foreign matter, but special functions are added to shoes. Alternatively, in many cases, shoes have special functions from the manufacturing stage. For example, climbers attach crampons to their shoes to prevent slipping.
  • Crampons may be integrated with shoes or may be provided so as to be detachable from shoes.
  • crampon integrated shoes have a problem in that the comfort that a user experiences when walking on a flat land is significantly deteriorated
  • detachable crampons have a problem in that a user has the inconvenience of attaching the crampons to shoes and then detaching the crampons from the shoes when slippery sections alternate with flat lands
  • EP 1 621 093 A2 discloses an anti-slip unit included in soles.
  • the present invention relates to an anti-slip unit as disclosed in independent claim 1 and to functional shoes as disclosed in independent claim 11. Preferred embodiments are disclosed in the dependent claims.
  • An aspect of the present disclosure provides functional shoes or an anti-slip unit for functional shoes that enables a user to conveniently switch between a crampon function and a normal shoe function without taking off the shoes.
  • Another aspect of the present disclosure provides a structure for improving the durability of an anti-slip unit of functional shoes that is capable of switching between a crampon function and a normal shoe function.
  • An anti-slip unit included in soles of shoes to provide an anti-slip function for the shoes includes a main body including an inner space and a spike through-hole that connects the inner space and the outside, a spike provided in the inner space so as to be movable along the spike through-hole, and a movable member that is provided in the inner space so as to be movable and that moves to allow the spike to be moved.
  • the movable member moves between a first position in which at least part of the spike is concealed in the inner space and a second position in which the spike is exposed outside the main body and an exposed state of the spike is maintained.
  • the anti-slip unit may further include a manipulation member that moves the movable member from the first position to the second position or from the second position to the first position.
  • Functional shoes for preventing slipping include a sole having a space inside, a spike provided in the interior of the sole so as to be movable in a vertical direction along a spike through-hole that is formed in the sole to connect the interior of the sole and the outside, and a movable member that is provided in the interior of the sole so as to be movable and that moves to allow the spike to be moved in the vertical direction.
  • the movable member moves between a first position in which at least part of the spike is concealed in the interior of the sole and a second position in which the spike is exposed outside the sole and an exposed state of the spike is maintained.
  • FIG. 1 is a side view illustrating functional shoes according to an embodiment of the present disclosure
  • FIG. 2 is a bottom view illustrating the functional shoes of FIG. 1 .
  • the functional shoes according to this embodiment include a sole 1 and an anti-slip unit 10 coupled to the sole 1 so as to be detachable.
  • the anti-slip unit 10 includes a plurality of spikes 100 movable therein.
  • the sole 1 may have a predetermined thickness and may include an inner space in which the anti-slip unit 10 is received.
  • the sole 1 may include an anti-slip unit receiving recess in which the anti-slip unit 10 is received, and the anti-slip unit receiving recess may be concavely formed toward the interior of the sole 1 from the bottom of the sole 1.
  • the sole 1 is provided at the lower parts of the shoes that contact the ground.
  • the sole 1 when contacting the ground, alleviates impacts (impacts experienced by a user) and increases frictional force with the ground to prevent slipping.
  • the anti-slip unit 10 may be installed at the front and the rear of the sole 1.
  • the spikes 100 movably installed in the anti-slip unit 10 may be concealed in the interior of the anti-slip unit 10 or may be exposed outside the anti-slip unit 10.
  • shoes include spikes to prevent slipping, but have a problem in that, when a user walks on a flat land, the spikes contact the flat land so that the user experiences discomfort.
  • crampons that are able to be attached to and detached from shoes also exist in the related art, but have a problem in that a user has the inconvenience of attaching the crampons to the shoes and then detaching the crampons from the shoes every time.
  • the functional shoes according to this embodiment are characterized in that the spikes for preventing slipping protrude from the sole or are concealed in the sole. More specifically, to enable a user to conveniently expose or conceal the spikes, the functional shoes according to this embodiment include a movable member installed in the sole so as to be rotatable and the spikes vertically moved by rotation of the movable member. Accordingly, the user may conveniently expose or conceal the spikes by rotating the movable member using a manipulation member, and thus user convenience may be improved.
  • FIG. 3 is a side sectional view illustrating the anti-slip unit of the functional shoes of FIG. 1 .
  • FIG. 4 is an exploded view illustrating the anti-slip unit of FIG. 3 .
  • FIG. 5 is a bottom view illustrating the movable member of the anti-slip unit of FIG. 4 .
  • FIG. 6 is a top view illustrating the movable member of the anti-slip unit of FIG. 4 .
  • the anti-slip unit 10 may include the spikes 100, a main body 200, the movable member 300, elastic members 400, the manipulation member 500, and a fastening screw 600.
  • the spikes 100 may each include a pointed protrusion at a lower end thereof and may provide an anti-slip function for the shoes.
  • the spikes 100 may be vertically movable, and may be concealed in the main body 200 or may protrude outside the main body 200.
  • the plurality of spikes 100 may be provided. Referring to FIG. 5 , the plurality of spikes 100 may be arranged at predetermined angular intervals with respect to the center of rotation of the movable member 300.
  • some of the plurality of spikes 100 may be disposed on a concentric circle far away from the center of the anti-slip unit 10, and the other spikes 100 may be disposed on a concentric circle close to the center of the anti-slip unit 10.
  • the plurality of spikes 100 may be disposed on the concentric circles with the axis of rotation of the movable member 300 as the center.
  • the plurality of spikes 100 may improve an anti-slip effect.
  • Each of the spikes 100 may include a spike body 110 and a spike head 120.
  • the spike body 110 may have a cylindrical shape with a predetermined diameter and may include a conical protrusion at a lower end thereof. Accordingly, when the user with the shoes on walks in the state in which the spikes 100 protrude outside the main body 200, the pointed protrusions may contact the ground to increase frictional force with the ground, thereby preventing slipping.
  • the spike head 120 may be connected to an upper end of the spike body 110 and may have a larger diameter than the spike body 110. That is, a step may be formed between the spike head 120 and the spike body 110 due to the diameter difference.
  • the spike head 120 may have a larger diameter than spike through-holes 230 of the main body 200, which will be described below. Thus, the spike head 120 may prevent the corresponding spike 100 from escaping from the anti-slip unit 10 and may restrict the length by which the spike 100 protrudes.
  • the edge of the spike head 120 that is adjacent to the movable member 300 may be rounded. Accordingly, the spike head 120 may be prevented from being worn or damaged by contact with the movable member 300 and may smoothly move when the spike 100 moves while being pressed by rotation of the movable member 300.
  • the edge of the spike head 120 may be chamfered at an angle corresponding to the slope of an inclined surface, which will be described below, and thus a movement of the spike 100 may be smoothly guided when the movable member 300 rotates.
  • the spikes 100 may be formed of a wear-resistant material and may be machined to have a smooth surface. Accordingly, a frictional force that may be generated when the spikes 100 make contact with the movable member 300 or the main body 200 may be reduced, and the spikes 100 may be prevented from being damaged.
  • the main body 200 may have an inner space S in which the movable member 300 is received.

  • the spike through-holes 230 may be formed in the main body base 210 to correspond to the positions where the plurality of spikes 100 are disposed.
  • the plurality of spike through-holes 230 may be formed at predetermined angular intervals. Some of the plurality of spike through-holes 230 may be provided on a concentric circle far away from the center of the main body 200, and the other spike through-holes 230 may be provided on a concentric circle close to the center of the main body 200. The plurality of spike through-holes 230 may be located on the concentric circles with the axis of rotation of the movable member 300 as the center.
  • Elastic-member receiving recesses 240 may be concavely formed on an inner surface facing a concealment direction (the upper direction) among the inner surfaces of the main body 200 that define the inner space S, along the peripheries of the spike through-holes 230.
  • the elastic-member receiving recesses 240 may be concavely formed on the upper surface of the main body base 210 along the peripheries of the spike through-holes 230. Steps may be formed between the elastic-member receiving recesses 240 and the spike through-holes 230 due to the diameter difference between the elastic-member receiving recesses 240 and the spike through-holes 230.
  • the elastic members 400 may be received in the elastic-member receiving recesses 240.
  • the elastic members 400 may be inserted into and fixed in the elastic-member receiving recesses 240 and may apply elastic forces to the spikes 100 to move the spikes 100 in the concealment direction (the upper direction).

  • the elastic members 400 may be disposed in the plurality of elastic-member receiving recesses 240, respectively.
  • the elastic members 400 may be springs.
  • a manipulation member through-hole 250 through which the manipulation member 500 passes may be vertically formed through the main body 200. That is, the manipulation member through-hole 250 may be vertically formed through the main body base 210 and may connect the inner space S and the outside of the main body 200.
  • the manipulation member through-hole 250 may have a diameter corresponding to the diameter of a manipulation member body 510, which will be described below, such that the manipulation member body 510 is rotatable in the state of being inserted into the manipulation member through-hole 250.
  • a thread for coupling the main body 200 to the sole 1 may be formed on the side surface of the main body 200.
  • An external thread may be formed on the outer circumferential surface of the main body 200, and an internal thread may be formed on the inner circumferential surface of the anti-slip unit receiving recess of the sole 1. The external thread may be fastened to the internal thread.
  • an external thread 260 may be formed on the side surface of the main body 200, and an internally threaded recess (not illustrated) may be formed on the inner circumferential surface of the anti-slip unit receiving recess of the sole 1.

  • the fastening screw 600 may be threaded into the manipulation member head 520 in the opposite direction to the direction in which the manipulation member head 520 is screwed into the movable member 300, and thus the manipulation member 500 may be effectively prevented from being released from the movable member 300.
  • the manipulation member body 510 may have a wrench recess formed therein, into which a wrench is inserted.
  • the wrench recess may be open in the exposure direction (the lower direction in the drawing).
  • the wrench recess may be implemented with a hexagonal recess 511.
  • the spikes 100 of the above-configured anti-slip unit 10 may be pushed by the movable member 300 to protrude outside the main body 200 and may be concealed in the main body 200 by the elastic members 400 when the force exerted on the spikes 100 by the movable member 300 is released.
  • a user may insert an Allen wrench into the hexagonal recess 511 and may rotate the manipulation member 500 in one direction to rotate the movable member 300 in the one direction, thereby allowing the spikes 100 to protrude outside the main body 200.
  • the user may rotate the manipulation member 500 in the opposite direction with the Allen wrench inserted into the hexagonal recess 511 to rotate the movable member 300 in the opposite direction, thereby allowing the spikes 100 to be concealed in the main body 200.
  • the user may expose or conceal the spikes 100 through the simple and convenient manipulation, and thus user convenience may be improved.
  • the manipulation member 500 and the movable member 300 are doubly coupled with each other by the fastening screw 600, and thus the coupling force between the manipulation member 500 and the movable member 300 may be enhanced. Accordingly, the anti-slip unit 10 may have high durability to prevent the manipulation member 500 and the movable member 300 from being separated from each other even though the user uses the anti-slip unit 10 while repeatedly rotating the movable member 300 in the one direction and the opposite direction.
  • the spikes are moved by a movement of the movable member that is provided in the inner space of the main body so as to be movable, and the movable member is moved by using the manipulation member without separating the anti-slip unit from the shoes.
  • the above-configured anti-slip unit of the present disclosure enables a user to conveniently switch between a crampon function and a normal shoe function without taking off the shoes.
  • the movable member is provided in the inner space of the main body so as to be movable, and the spikes are provided in the inner space so as to be movable along the spike through-hole. Accordingly, the anti-slip unit may be protected from the outside of the shoes and may be structurally stable, and thus the durability of the anti-slip unit may be improved.
