Definitions

  • the invention relates to a shoe with retractable wheels, as well as a shoe sole comprising retractable wheels.
  • Document GB-334,782 describes a roller skate, in which the wheels are mounted on a hollow body in the form of a cradle.
  • the cradle-shaped hollow body is mounted to oscillate by means of a linkage between two extreme positions in one of which the wheels carry the cradle-shaped body while in the other extreme position, the cradle-shaped body rests On the ground.
  • This roller skate device requires the use of a complex mechanical linkage and mechanical locking means which significantly raise the feet of the user in an uncomfortable position.
  • Document US Pat. No. 3,884,485 relates to a retractable roller skate comprising a body adapted to be attached to a shoe, a plurality of rollers carried in rotation on retraction means and housed in said body.
  • the retraction means serve to move said rollers in one of two distinct positions: in a separate position, the rollers are completely housed inside the body and, in the other separate position, they protrude at least partially from said body .
  • the retraction means comprise pivoting levers lockable by means of a manual control button with spring return.
  • This device is similar to the previous one in that it provides pivoting levers around fixed axes carrying rollers housed in a relatively rigid sole of great thickness.
  • Document US-4 333 249 describes a transformable device for the use of sports.
  • This device is a roller skate lockable between two positions by means of pivoting levers capable of being locked between a retracting position and a rolling position.
  • This device is adaptable to a shoe, but does not itself constitute a shoe adapted to the foot of a user.
  • the object of the invention is to provide a shoe comprising rollers retractable between two positions, not requiring the use of lever mechanisms of the prior art and allowing continuous practice of roller skating and walking in an ergonomic position. not tiring the user.
  • the subject of the invention is a shoe with wheels, of the type comprising at least one wheel front and at least one rear caster; the front and rear rollers being movable between a first position of contact with the ground and a second raised position, characterized in that the front and rear rollers are interconnected by at least one flexible link passing inside the sole, so as to move the front and rear rollers simultaneously using traction means connected to said flexible link.
  • the invention also relates to an adaptable shoe sole or integral with a shoe of known type, provided with front and rear rollers movable between a position of contact with the ground and a raised position, characterized in that the sole comprises cavities capable of accommodating at least two flexible links, the first of which connects the front and rear casters and of which at least a second is capable of being pulled to move the front casters and back from one of said two positions to the other of said two positions.
  • a shoe with wheels according to the invention comprises an upper part 1 shown in dotted lines intended for receive the foot of the user and a sole 2 adapted to the upper part 1, preferably integral with the latter.
  • Two front rollers 3a and 3b and two rear rollers 4a and 4b can be moved between a first position of contact with the ground shown in solid lines and a second raised position shown in dotted lines.
  • the running surface 5 of the rollers 3a, 3b 4a, 4b is preferably made of an anti-slip material of the rubber gum, polyurethane or polyvinyl chloride (PVC) type.
  • Each roller 3a, 3b, 4a, 4b is mounted for free rotation on an axis 6 secured to a support 7 itself secured to a plate made of flexible material 8.
  • flexible material mention may be made of plastics of the such as polyethylene, polypropylene, polyvinyl chloride or other resilient materials capable of undergoing slight elastic deformation.
  • the sole 2 has in its thickness two cavities 9 and 10 adapted to the contour of the support plates 8 so as to constitute means for guiding the plates 8 during a displacement in translation under the action of traction means connected to said plates support 8.
  • the support plates 8 carrying the front and rear rollers are connected to each other by a flexible link 11 passing inside the sole 2, so as to simultaneously move the front rollers 3a, 3b and rear 4a, 4b using traction means.
  • the traction means comprise two flexible links 12 and 13 having a projecting end 12a and 13a comprising a gripping means 14.
  • gripping means 14 there may be mentioned a lever, a zipper, a ring, a loop, a hook or the like.
  • All the flexible links 11 to 13 pass inside the sole 2 in a corridor of low height and width adapted to the width of the flexible link.
  • the flexible links 12 and 13 can be locked in position using blocking means cooperating with the gripping means 14; for this purpose, the upper part 1 of the shoe may comprise locking members 15 of the hook type, arranged at a spacing greater than the width of a flexible link 12 and 13 and less than the width of a gripping means 14
  • the blocking means cooperating with the gripping means can constitute the male part of the cooperating female part, or vice versa; one can also use for blocking a button cooperating with a hook, a fastening loop cooperating with a ring or hook, a quick coupler of the "velcro" type (registered trademark), a snap button or any other similar means preventing the return to flexible link 12 or 13.
  • the operation of the invention is as follows: after having detached the rear gripping means 14 from its locking means 15 (FIG. 1) and after having pulled on the front gripping means 14 in a translation passing all of the members coupled to the front lever 14 from the position shown in solid lines to the position shown in dotted lines, an overall displacement of the plates 8 is brought forward and backward from the position shown in solid lines to the position shown in dotted lines.
  • This movement of the plates 8 connected together by the flexible link 11 causes the front rollers 3a, 3b and rear 4a, 4b to pass from the first position of contact with the ground shown in solid lines to the second raised position represented in dotted lines.
  • the invention thus allows, in the position of contact with the ground shown in solid lines, movement on casters; while in the position shown in dotted lines, the invention allows normal walking.
  • a particular advantage of the invention lies in the fact that due to the small size of the passages of the flexible links 11, 12 and 13, the sole 2 is perfectly flexible and allows normal walking without fatigue.
  • the sliding cavities 9 and 10 are formed directly in the thickness of the sole or are coated at least partially at the places of friction with a material more resistant than the composition of the surface of the sole in contact with the ground.
  • the cavities 9 and 10 are slightly offset from one another in the horizontal plane in an arrangement substantially parallel to the sole of the foot following a slight upward slope from back to front. It is then necessary that the passage of the flexible link 11 is carried out descending from the rear towards the front, so as not to excessively increase the thickness of the sole 2 so that the thickness of the sole 2 is comparable to the thickness of a walking or sports shoe sole of a type known per se.
  • This reversal of slope also provides a natural anti-return blocking effect ensuring by itself locking plates and axles in a predetermined position.
  • the front rollers 3a, 3b and rear 4a, 4b are preferably mounted removable to allow their replacement in the event of excessive wear.
  • the axis 6 is removable relative to the support 7: this axis 6 can be constituted by a screwed assembly or by an axis retained in place by elastic rings or the like.
  • the traction means do not include flexible links 12 and 13 described with reference to Figures 1 and 2; these traction means comprise rings 16 fixed on tabs projecting laterally from the sole 2, capable of cooperating with blocking means 17 of the hook, reinforced rivet or similar type to block all of the support plates 8 and of the flexible link 11 in the position shown in solid lines of contact with the ground or in the position shown in dotted lines, raised and without contact with the ground.
  • the rings 16 are pivotally mounted on lateral lugs 18 so as to pivot around a horizontal axis in the direction of the arrows P.
  • the gripping means 16 serve simultaneously as locking means locking the front rollers 3a and rear 4a in one or the other of said positions of contact with the ground or raised.
  • another embodiment according to the invention comprises an upper part 20 intended to receive the foot of a user and a lower part 21 forming a sole.
  • the sole 21 has two through recesses 22 and 23 in which are mounted prisoners a front axle 24 and a rear axle 25.
  • the front and rear axles 24, 25 are connected to each other by a flexible link 26 passing through the interior of the sole 21.
  • a flexible link 27 passing inside the sole 21 is connected to the front axle and a flexible link 28 passing inside the sole 21 is connected to the rear axle.
  • the flexible front links 27 and rear 28 form with traction rings 29 and 30 traction means able to move the axles between a first position of contact with the ground not shown and a second raised position shown in solid lines.
  • the rings 29 and 30 are fixed to the straps 27 and 28 by snaps 31 and 32 able to cooperate with the rivets of corresponding snaps 33a, 33b cooperating with the button 31 and 34a, 34b cooperating with the button 32.
  • the through cavities 22 and 23 in which the axles 24 and 25 are trapped constitute guide conformations for the movement of the axles between a position of contact with the ground and a raised position.
  • the front sliding corridor 23 integral with the sole 21 has a shape of a ramp rising in the direction of the front with a first horizontal part, an inclined part with change of direction corresponding to an inflection point and a second horizontal part: the corresponding movement of the axles is thus imposed by the sliding corridors 22 and 23 to follow a trajectory similar to the profile of a slide.
  • the sole 21 can have a very low height imposed only by the need to house the front guide passage 23; in addition, the diameter of the rollers 34a, 34b, 35a, 35b is independent of the thickness of the sole and can be arbitrarily chosen by having a diameter significantly greater than the thickness of the sole 21, as shown in FIG. 5 with regard to the front part of the sole 21.
  • the sole 21 has a thickness comparable to the thickness of the soles of sports shoes of known type and has great flexibility. This characteristic allows the sole to be folded during walking, thus providing ergonomic walking conditions which do not tire the user of the shoe according to the invention.
  • the sliding corridors 22 or 23 are advantageously made of a material resistant to abrasion and having a hardness greater than that of the material of the sole in contact with the ground.
  • the front ends 22a and 23a of the sliding corridors constitute stops for the axles 25 and 24 in the raised position, while the rear ends 22b and 23b constitute stops for the axles 25 and 24 in the lowered rolling position in contact with the ground.
  • rollers 34a, 34b, 35a, 35b are formed by overmolding of an elastomeric material or a polyurethane on ball bearings 36 or roller bearings of a type known per se retained on the axles by nuts 37.
  • the overmolding of the tread on mechanical bearings of known type thus ensures perfect resistance to lateral impacts and prevents the tread of the rollers 34a, 34b, 35a, 35b from coming off.
  • the flexible links 26 to 28 are formed from a single continuous strap, belt or strip on which the axles 24 and 25 are fixed, being parallel to each other.
  • the abutment surfaces 22a, 22b and 23a, 23b are also parallel to each other and orthogonal to the longitudinal axis of the shoe, so that the axles movable in the direction of the arrows D in FIG. 4 remain constantly parallel to each other during their displacement.
