Definitions

  • the present invention relates to a shoe having wheels incorporated in the sole and laterally unfoldable by means of a mechanism.
  • This shoe can be used alternately for walking and driving.
  • the present invention relates more particularly to shoes which comprise one to four wheels, placed for walking horizontally in housing of the sole, and which for rolling, can be pivotally rotated about a longitudinal axis and locked in substantially vertical position projecting downward on each side of the sole and thus transforming the shoe roller skate.
  • the soleplate is relatively rigid because of the metal plate and can not deform freely during walking.
  • the mechanism under the soleplate can become dirty and the overall weight is relatively high.
  • the object of the invention is to provide transformable shoes, light but robust, with a thin and flexible sole that can deform freely during walking, with large diameter wheels and a single and simple control device.
  • the invention can adapt to any type of shoes, with or without ankle support.
  • the roller shoes according to the invention make it possible to move very quickly and easily from walking to rolling, and vice versa and they are ideal for both uses.
  • the soleplate equipped with the rollers presents to the ground only closed surfaces coated with rubber offering only a low risk of fouling.
  • the mechanism according to the invention used to attach the casters to the boot, allows effective and safe locking of the casters in the rolling position and in the running position, without play or vibration, and a quick passage, without effort and without tools. one position to another.
  • the invention teaches a versatile shoe intended alternately for walking or driving, comprising a sole in which are provided housing; casters, which for walking are retracted in a horizontal position in the housing of the sole and for rolling are deployed under the sole in vertical position; and a mechanism for actuating the rollers for moving the rollers alternately from one position to the other by lateral pivoting.
  • the rollers are disposed on either side of the sole in the manner of a roller skate.
  • a versatile shoe 1 according to the invention will now be described in detail with reference to the figures.
  • the shoe 1 comprises a sole 2 in the outer edge of which are formed housing 3, 4, 5 and 6, each for receiving a wheel 7, 8, 9 or 10.

  • the figure 3 shows that according to a preferred embodiment of the invention the front rollers 7 and 10 are located at least partially at the rear of the line 40 which is the bending line of the sole 2.
  • the sole When walking, the sole remains substantially flat at the rear of this line, while the part of the sole located at the front of this line 40 undergoes significant bending.
  • the rollers 7 and 10 located under the front part of the sole 2 will be slightly spaced from each other, to be able to leave in the sole 2 an intact central zone 32, between the housings 3, 5 intended for the front rollers 7, 10, which connects the deformable zone of the sole 2 located at the front of the bending line 40 of the shoe 1 to the rear zone of the sole 2, which may be more rigid, located at the rear of this flexion line 40.
  • This zone 32 is intended to give the sole 2 a homogeneous bending behavior, and to compensate for the weakening caused by the housings 3 and 5 of the rollers 7 and 10.
  • This central zone 32 will also support a portion of the weight of the user, when walking.
  • the figure 5 represents a section through the wheel 7 in the horizontal position.
  • the rollers 7, 8, 9, 10 preferably have a hollow rim 22.
  • a sole member 39 integral with the sole 2 and preferably substantially cylindrical, may advantageously pass through the rim 22 of the wheel 7 and bear on the ground 41 when the wheels are in position horizontal walk.
  • Each wheel preferably comprises a tread 42 and a cheek 38 directed towards the ground and intended to protect the wheel.
  • These elements 42 and 38 are for example made of an elastic material of the rubber or polyurethane type.
  • Each rim 22 is secured to the hub 21, 23, 25 or 26 of the wheel concerned. On the figure 5 , the rim 22 is integrally connected to the hub 21.
  • the cheek 38 of each wheel is elevated relative to the ground when the rollers are in a horizontal position.
  • the casters and the mechanism that supports them do not undergo efforts during normal walking but only occasional efforts for example on sandy soil.
  • the figure 6 shows a second variant of the angular locking device of the rotating elements 30, 31.
  • the latch 33 is pushed towards the flange 27 of the plate 60 by the spring 36.
  • the latch 33 comprises a spring blade 24 who is in solidarity with him.
  • This leaf spring 24 has a free position 24 'shown in dashed lines.
  • the spring blade 24 is compressed and its end 37 pushes the rotating member 30 in a vertical position.
  • the position of the end 37 of the leaf spring 24 is defined so that the wheel 7 is pressed against the bottom 59 of the housing of the sole 2.
  • the games are eliminated and the casters 7, 8, 9, 10 are elastically pressed against the bottom of their respective housing in a horizontal position, which avoids noises and clicks during walking or running.
  • a flexible envelope (not shown) can cover the angular locking device comprising in this case the lock 33 as well as its hinge 53 and hub 54 and its spring 36. It can also cover one or more other elements such as the plate 60 , the rotating elements 30, 31, the longitudinal axes 15, 16 and / or the bearings 17, 18, 19, 20.
  • This envelope allows movement of the movable elements and the lock 33, but protects the assembly against dirt and grease. shocks.
  • the figure 5 shows that the center of gravity of the wheel 7 is offset with respect to the longitudinal axis 15.
  • the longitudinal axes 15 and 16 are rotated by the off-axis weight of the rollers 7, 8, 9, 10.
  • Such a pivoting could also be caused by an elastic element acting on the rotating elements, the longitudinal axes or the wheels. Casters 7, 8, 9 and 10 are then found, by gravity or elastic effect, in an intermediate position. The angle of inclination of the rollers in this intermediate position is between the vertical and the horizontal.

  • the device blocking the rollers 9, 10 in the horizontal position.
  • the device locks the casters 7, 8 in the vertical position.
  • Each rotating element 45 has substantially the shape of a quarter disc centered on the longitudinal axis 15 or 16 corresponding and integral thereof.
  • a spring 47 preferably double and symmetrical, integral with the flange 27 of the plate 60 abuts radial surfaces of the rotating member 45 to block the rotation.
  • the rotating element 45 is limited in rotation in the other direction by a pin 46 secured to the flange 27. Thus it is sufficient to press down on the spring 47, more precisely on its two symmetrical branches, to release the rotation of the rotating assemblies and rotate the rollers 7, 8, 9 and 10 in the intermediate position.
  • This support can be performed by means of several rods or cables such as 48, preferably actuated by a common button to act simultaneously on each of the springs 47.
  • the multipurpose shoe according to the invention preferably comprises a lever or a single actuating button which allows to unlock the angular locking device.
  • This lever or this actuation button can be operated manually, by typing for example against a sidewalk or preferably by pressing a specially equipped area of the other shoe.
  • the double and symmetrical spring 47 can be replaced by levers articulated in the center of the wing 27 and pushed against the rotating elements 45 by springs.
  • each rotary assembly By sliding the right and left blocking elements 50 horizontally towards the middle of the wing 27, the rotation of each rotary assembly is released.
  • the rotating elements 49 each have a lug 57 which limits the rotation of the rotating assemblies as soon as the vertical position of the rollers 7, 8, 9, 10 is reached, bearing against the corresponding blocking element 50.
  • the longitudinal axes 15 and 16 are shown straight. According to a variant of the invention, the central portion of these axes, located between the bearings 17, 19 and the hubs 23, 26, can follow the curvature of the sole. In this way the axes 15 and 16 are close to the sole 2 and can be supported under it.
  • This locking can consist of locks, actuated simultaneously by the lock 33 or by a separate lever, and which act for example directly on the rims 22.
  • the figures 10 and 11 illustrate a variant with rotating castors in pairs when turning.
  • the aim is to obtain oblique geometric axle lines and if possible at least for one of them and in particular the geometric axle before being radiating or approximately radiating, that is to say say in the extension or approximately in the extension of a radius of the turn circle or the average circle of turn.
  • the wheels are thus oriented correctly during the turn. In this way wear is limited and the balance of the wearer is improved in the curves.
  • the inclination of the sole 2 causes the correct orientation of the two pairs of pairs of casters torque and any variation in inclination corresponds to a variation of orientation pairs of casters or at least a pair of casters.
  • the curving becomes more comfortable and safer.
  • the inclined axes 61 and 62 each carry at the end a bearing member 65 and 66 acting by rotating on itself and being in contact with the corresponding pivoting plate to rotate in the desired direction that is to say that determined by the inclination of the sole 2, resulting for each inclined axis simultaneous pivoting of the two wheels of the same pair of wheels.
  • each plate is driven in motion for example by pivoting about its own axis by the effect of the piece of land of the corresponding inclined axis.
  • turntables 28 and 60 are then no longer parallel to each other but their front and rear edges are directed towards the center of the turn and the shoe inclined to the right or left will automatically describe a turn in the same direction.
  • the ends of the axes 15 and 16 are articulated, preferably by a multidirectional hinge.
  • FIG. 10 An example of extensible axes is illustrated by the figure 10 on which can be seen 15 and 16 telescopic shafts made in two parts 67, 68 and 69, 70 and at their ends articulated joints of the cardan type 71, 72 at the rear and 73, 74 at the front.
  • angular deflections may be limited, it is possible to envisage, from a technological point of view, a gimbal equivalent by elastic deformation of two parts or by deformation of intermediates or inserts providing a flexible connection.
