Definitions

  • the present invention is in the field of urban mobility, and relates to an individual means of transport allowing walking at a higher speed than that of normal walking, without any skating movement, without running backswing, and without modifying the rhythm, amplitude or longitudinal stability of natural walking.
  • This means of motorized transport constitutes a new solution for individual mobility, in a rather urban environment, which achieves an advantageous combination of walking and the moving sidewalk, and which could be defined as a kind of "on-board and progressive treadmill". which takes place under the walker's shoes.
  • the invention thus combines more advantages than all currently existing means of individual urban transport, including in particular speed, safety, comfort of use, very small personal size and immediate control without learning.
  • each shoe houses a relatively rigid plate connected to caterpillars in the toe and heel parts, respectively, which are connected by a relatively flexible part. The whole is designed to neutralize forces disrupting its functioning while walking while the soft part helps the shoe bend naturally to maintain natural balance and walking motion. Also, the soft part can be fitted with ribs or hinges for easier bending than twisting.
  • the relatively stiff front and back plates can be made of materials that can be twisted and bent, but to a lesser extent than the soft part.
  • the patent application WO1995035136A1 relates not to motorized equipment, but to a track roller skate unique “roller” type.
  • the problem is not the same as that of a motorized skate.
  • the purpose of this non-motorized single-track skate is to improve the power transmitted by the supporting foot during a “skate” movement.
  • FIG. 1 represents a very schematic view of the mobility equipment formed by a pair of motorized skates (1, 2) seen from below, the soles of the feet being represented to facilitate understanding of the operation and not forming part of the invention.
  • Each shoe is formed by a rigid plate (30) having the general shape of a sole supporting a front mobile train (10) and a rear mobile train (20).
  • This plate is formed of two parts articulated along a transverse axis (39), the front part (37) corresponding substantially to the toes, and the rear part (38) corresponding to the sole and the heel.
  • the front (10) and rear (20) axles are motorized by a common motor (50) inside the roller common to the front and rear axles, for example an electric motor with an external rotor, driving the tracks.
  • This motor can be equipped with a reduction gear, for example in the form of an epicyclic gear train, and with a step-by-step actuator controlled according to commands transmitted by the user.
  • the rear axle (20) also has a housing for receiving electric batteries (51 to 54).
  • the longitudinal axis (16) of the nose gear (10) forms an angle of approximately 15° with the longitudinal axis (35) of the plate (30).
  • the longitudinal axis (26) of the rear axle (20) forms an angle of approximately 15° with the longitudinal axis (35) of the plate (30).
  • angles can be adjustable to adapt to the valgus of the user, for example between 10 and 20°.
  • the locomotion equipment consists of a pair of skates comprising rolling or sliding trains (10, 20) connected to a sole (30) which is fixed to the feet either in the form of special shoes, or as additional skates attached under the shoes .
  • Each pad (1, 2) is made up of a frame (22) equipped with moving trains (10,11; 20,21), that is to say rolling (12, 13, 22, 23) or sliding on the ground, each moving train being an integral assembly of wheels, tracks, or sliding segments, all these moving trains having the same direction of movement, that is to say rolling or sliding, and a plate , specific in the case of a sole (30) fixed under the shoes, or constituted by the sole (30) in the case of a special shoe.
  • the plate (30) is mounted with an orientation, in its own plane, obliquely relative to the direction of movement of the mobile trains (10, 20).
  • the plate (30) can be mounted at a point of the frame on a means of rotation (40), pivot or ball-and-socket system, making it possible to preset this orientation.
  • the oblique orientation of the frame can create overhangs of the foot in relation to the support points of the rolling or sliding gears, which can induce lateral instability of the pads if the width of the support polygon defined by the position rolling or sliding trains is insufficient.
  • the present invention is based on the lateral offset relative to each other of the rolling or sliding gears. This shift makes it possible to position said rolling or sliding trains along the longitudinal axis of the plate (30) to support the support points of the foot, while letting them roll or slide in the direction of movement, that is that is to say obliquely relative to said longitudinal axis. Consequently, the width of the plate can be reduced to that of said support polygon.
  • the pivot can advantageously be made of elastic material of suitable stiffness, allowing the plate which tilts with the foot along its roll axis to deform the pivot such that the chassis and its mobile trains remain flat parallel to the ground.
  • This configurable orientation of the plate relative to the direction of movement of the moving gears can be obtained by means of rotation (40) or swiveling, making it possible to preset the orientation of the plate relative to the chassis, and which can be coupled to a locking device (7) making it possible to obtain the blocking of the rolling direction during use of the skates.
  • an articulated mechanism can advantageously be produced which provides a coupling between a point of the plate (30) and each lateral positioning mechanism.
  • This mechanism can be an articulated parallelogram, maintaining the parallelism of the rolling or sliding gears, and coupled by a pivot at a point of the plate.
  • spacer-tightening cams actuated by the rotation of the plate on its pivot, with, if necessary, transmission rods to the rolling or sliding gears to be shifted.
  • slides can advantageously be used, which hold the moving gears on the chassis while allowing them to slide laterally, each being coupled to an articulated attachment point (5) of the plate.
  • each shiftable mobile train can then be obtained thanks to this coupling if the orientation of the plate is itself locked.
  • the common roller can advantageously be composed of an inner support cylinder, around which are mounted the outer cylinders acting as pulleys, at least one of them being free to slide laterally along the inner cylinder during adjustment.
  • a first particular embodiment of the invention is an in-line roller skate consisting of a sole (30) equipped with two mobile running gears (10, 20), each comprising two in-line wheels (12, 13; 22, 23) , and a plate mounted on the chassis by a pivot (40) making it possible to preset its orientation obliquely with respect to the direction of travel of the running gear ( FIG. 2 ).
  • the pivot (40) is made of elastic material of the polymer type, its stiffness sufficient to keep the plate stable in the normal position (excluding pushing force), but letting it tilt in roll with the foot when pushing on the skate, so that the four wheels remain flat on the ground when pushing the foot if the two running gears are offset.
  • the shift mechanism is a slide rail (6), integral with the front running gear, and sliding laterally along a rail fixed to the chassis.
  • the coupling of the plate to the lateral offset mechanism (6) of the front running gear is obtained by a fork (5) secured to the front of the plate, and acting laterally on the offset slider (6).
  • the rail secured to the frame incorporates a spring pressing it against the slide (6), the two facing surfaces being notched (7) so as to obtain locking in all conditions (free skate or shod).
  • the offset is preset manually, by temporarily moving the front running gear away from the plate, which neutralizes the compression force of the spring, and adjusting the lateral offset. Locking occurs as soon as the spreading force is released, and is reinforced by the weight of the skater when he places his foot on the ground.
  • a second particular embodiment of the invention is a skate with two tracks ( FIG. 1 ), consisting of a frame equipped with two moving trains (10, 20), each consisting of a caterpillar with two rollers at the ends, said caterpillars rolling in the same direction.
  • the plate (30) supporting the shoe is mounted on a pivot making it possible to preset its orientation, in its own plane, obliquely with respect to the direction of travel of the running gear (16, 26).
  • the mechanism for shifting and locking the front running gear, as well as its coupling means to the plate, are identical to those of the roller constituting the first particular embodiment.
  • a variant of this second particular embodiment consists in pooling the rear roller of the front track and the front roller of the rear track (39) .
  • the pair of rolling or sliding skates attached to the feet can be made in the form of special shoes, or as additional skates attached under the shoes, each skate being composed of a frame equipped with several mobile trains, all rolling or sliding according to the same direction, and a plate, specific in the case of an additional skate, or constituted by the sole in the case of a special shoe, characterized in that the said plate is mounted obliquely with respect to the direction of movement of the mobile trains, and that at least one of the mobile trains is offset laterally with respect to the others so that all the mobile trains support the support points of the foot while making it possible to maintain the width of the pad close to that of the foot.
  • At least one wheeled train At least one wheeled train
  • the pair of runners comprises, for at least one of its mobile trains (10, 20), a fixed assembly of wheels rolling in the same direction, at least one of which, for each train, is driven by the engine (50).
  • each train (10, 20) includes a motor wheel.
  • At least one crawler train At least one crawler train
  • the pair of pads comprises, for at least one of the moving gears (10, 20), a caterpillar.
  • At least one of the mobile trains (10, 20) is composed of segments which can slide on the ground.
  • the means for connecting the plate (30) with the moving gears (10, 20) are made of elastic material allowing the plate (30) to be tilted in roll without taking off all or part of the moving gears from the ground.
  • the plate (30) is mounted on the chassis by means of rotation making it possible to preset the orientation of the plate with respect to the direction of movement of the moving gears (10, 20), said rotation means being coupled to a locking device making it possible to obtain the blocking of the rolling direction during use of the skates.
  • a device for locking the orientation of the plate is obtained by notching the faces of the elements facing each other, held by an elastic system when the pad is not on the ground, said elastic system allowing the preset to be modified by hand, and being arranged in such a way that the weight of the user on the skate reinforces the effect.
  • each mobile train (10, 20) is shiftable and comprises a means of coupling with the orientation of the plate (30) so that the shift mobile trains optimizes the support polygon in relation to the support points of the foot on the plate.
  • the means for coupling the plate (30) to the lateral shift mechanism of a moving train (10, 20) is an articulated mechanical connection between the plate and the shift mechanism.
  • the lateral shift mechanism of an undercarriage (10, 20) is a slide (6), which holds the undercarriage on the frame while allowing it to slide laterally under the action of the articulated link.
  • each of the skates is completely integrated into a shoe.
