Definitions

  • the present invention relates to a shoe comprising a front part and a back part placed on a sole, wherein the sole incorporates a hinge pivotally connecting the front part and the back part for opening and closing the shoe.
  • the shoe also comprises a locking mechanism for locking the shoe in closed position .
  • Such shoe that may be opened and closed by turning the front part of the shoe relative to the back part facili ⁇ tates stepping in and out the shoe. This is beneficial in any case but in particular for persons that for whatever reason experience difficulties in stepping in and out shoes.
  • EP 2 173 208 discloses such shoe.
  • the locking mecha- nism is integrated in the axis of the hinge.
  • the drawback of this shoe is that the locking mechanism is relatively small for the forces exercised on it and that it may show consider ⁇ able wear in time, resulting in failure. For functional reason the tolerance in the locking mechanism should be small, how- ever this results in a less reliable and smooth locking of the locking mechanism.
  • Dutch patent 1020208 discloses such shoe.
  • the locking mechanism consists of a slide in the back part of the sole that is forced by a spring in a cavity in the front part of the sole.
  • the hinge consists of two small pins and the pins together may not suffice to absorb all power exerted on it.
  • the pins are consequently vulnerable for deformation.
  • the sleeve absorbs part of the forces exerted on the shoe and may deform as well as the cavity. Such deformation may hinder a correct locking and unlocking. Moreover in time this may result in wear and larger tolerances between slide and cavity, which is unacceptable for comfort reason.
  • the presence of the guide way for the slide in the back part of the sole results in a less stiff sole.
  • the shoe is also unstable in open posi- tion and may, simply places on the ground and under gravity, turn itself in the closed and locked position.
  • the present invention intends to solve one or more of the problems of the prior art as described above, and it is in particular an objective of the invention to provide a shoe with a pivoting sole that is robust and durable.
  • a front part and a back part of the hinge are provided with first respectively second locking means with essentially two possible relative positions towards each other, a first position with the shoe unlocked and a sec ⁇ ond position with the shoe locked.
  • first respectively second locking means with essentially two possible relative positions towards each other, a first position with the shoe unlocked and a sec ⁇ ond position with the shoe locked.
  • the axis of the hinge and the locking mechanism are separate and a strong and durable shoe is obtained.
  • the locking forces will be absorbed by the first and second locking means and are directly trans ⁇ ferred to the hinge.
  • the axis of the hinge may be optimally designed for its pivot function. In particular it may be places all over the width of the shoe.
  • the first and the second locking means may comprise a cam, the cam of the first locking means and the cam of the se ⁇ cond locking means resting against each other in closed posi ⁇ tion of the shoe.
  • These cams will typically have a sufficient large contact area in order to absorb the large forces exerted on it.
  • bearing means may be provided, in particular a wheel. To prevent wear of the cams the cams may have rounded edges.
  • the hinge is provided with a torsion spring forcing the shoe in open position.
  • the shoe is then stable in open position and may be simply placed on the ground without turning itself in the closed and locked position.
  • the torsion spring will force the first and second locking means, in particular the cams, in locked position against each other compensating a possible tolerance between them and enhancing the locking and the comfort of the shoe.
  • the back part of the hinge may at its rear be provided with a bridge, when stepping in the shoe, creating leverage against the force of the torsion spring and facilitating closing of the shoe.
  • the first or second locking means may according to the invention be provided on a slider, which slider is slide ably connected to the hinge. This provides a simple and smooth way of locking and unlocking the shoe.
  • a spring may be pro- video! between the slider and the hinge, pressing the slider in its position for locking the shoe. The shoe is then always safely locked in closed position. Locking will automatically occur when closing the shoe. Only for unlocking and opening the shoe the slider should be operated.
  • the slider may for this be provided with a handle for unlocking, manually or with a foot.
  • the hinge of the shoe according to the invention re ⁇ quires sufficient stiffness, in particular the back part of the hinge, and according to the learning of the invention the hinge may therefore be provided with reinforcement ridges.
  • the heel area may be designed less stiff.
  • the hinge preferably has a front edge skewed with respect to the hinge.
  • Figure 2 a shoe according to the invention in closed posi ⁇ tion
  • FIG. 3 a hinge of a shoe according to the invention in bottom view
  • Figure 4 a schematic view of the hinge with cams and a torsion spring
  • FIG. 7 a hinge according to the invention in bottom view and provided with reinforcement ridges
  • FIG 8 a hinge according to the invention in bottom view and provided with a skewed front edge.
  • the shoe 1 is shown in open position with a foot 2 of person stepping in the open shoe.
  • the shoe comprises a front part 3 and a back part 4 and is provided with a sole 5.
  • the front part consists of upper 6 connected to stiffening means 9.
  • the back part consists of upper 7 connected to stiffening means 10.
  • a hinge 8 is incorporated in the sole 5.
  • the back part 4 of the shoe may be turned around this axis 8c of the hinge 8 towards the front part 3 of the shoe such that the shoe is closed and the edges 11 and 12 rest against each other, as is shown in Figure 2.
  • the shoe 1 is locked in closed position.
  • the bottom view of hinge 8 in Figure 3 shows that the back part of the hinge 8b is provided with second locking means in the configuration of a cam 13.
  • This cam 13 rests in closed position against a first locking means in the configu ⁇ ration of cam 16 of slider 14 on the front part of the hinge 8a.
  • the slider 14 is slide ably connected to the front part 8a of the hinge. Between the slider 14 and the front part of the hinge 8a a spring 18 is placed forcing the slide in a position in which cams 15 and 16 rest against each other and conse ⁇ quently the shoe is locked.
  • the slider 14 is provided with a handle 19. By pushing the handle 19 in the direction of hinge 8, the slide will move against the force of spring 18 from its first and locked position to its second free position.
  • the cams 16 moves relative to cam 13 to its second position in which there is no contact between cam 16 and cam 13 and the hinge 8 is consequently unlocked.
  • Front part 8a and back part 8b of the hinge may be turned around axis 8c in order to open the shoe.
  • a torsion spring 17 is provided which forces the back part 8b and the front part 8a to turn around axis 8c to an open position of the shoe. In this open position the torsion spring 17 also prevents the shoe locking itself under gravity and accordingly the shoes may be stored in open position .
  • the torsion spring 17 is placed around axis 8c with its legs placed at the top side of both hinge parts 8a and 8b.
  • On back part 8b of the hinge cam 13 is provided.
  • the front part 8a of the hinge slider 14 is provided with cam 16.
  • Cam 13 and cam 16 rest against each other and the torsion spring 17 presses them together compensating for possible tolerance between them. In this way both cams 13 and 16 make firm contact for an optimal locking. Deformation of the cams will be prevented by suitable design choices of material and dimensions of the cams.
  • the edges of the cams 13 and 16 are rounded in order to facilitate relative movement between them.
  • FIG. 5 An embodiment of the of slider 14 is shown in more detail in Figure 5,
  • the slider 14 is placed in guide ways in both lateral edges 20 an 21 of front part 8a of the hinge. Be ⁇ tween the slider 14 and lateral edge 20 the spring 18 is posi- tioned. The spring 18 itself is locked in a cavity 29 of slide 14 between a smaller extension 27 and a longer extension 28.
  • slider 14 is shown in Figure 6.
  • slider 14 is only placed in one lateral edge 20 of slider 14. It is further guided and connected to the front part 8a of the hinge by nock 22.
  • nock 22 As this embodiment requires only a guideway in one lateral edges of the hinge, more design freedom is obtained for the shoe, which shoe may be aesthetically optimized.
  • the cams may be provided with bearing means, in this embodiment of Figure 6 the bearing means consist of wheels 23.
  • the hinge according to the invention has to absorb considerable forces exerted on it by the cams.
  • the hinge 8 of Figure 7 is provided with reinforcement ridges, in particular in longitudinal di ⁇ rection. For comfort reason it may desirable to have the hinge 8 less stiff in the area of the heel for which reason a less stiff area 25 is foreseen to provide sufficient damping.
  • Unwinding of the foot requires also optimal flexibil ⁇ ity of the foot at its front part. Unwinding of the foot takes place along a skewed line. For comfort reason the hinge 8 of Figure 8 is also provided with a skewed front edge compared to the hinge axis 8c. In this way sufficient stiffness is ob ⁇ tained without losing comfort.
