Definitions

  • the aim of the present invention is a device capable of carrying out a stepping movement, approximately like the movement a person makes when walking.
  • a toy consisting of a transparent sphere containing a doll pivoted on a diameter of the sphere; the sphere moves by rolling and/or oscillating and the doll always stays in the upright position.
  • FR-A-1 002 057 discloses a stepping movement toy as said in the preamble of claim 1.
  • Said toy as taught can be embodied only as a string-pulled toy, which is pulled by a user; no disclosure has ever been made of a stepping device whereon a user can ride, or seat or stand, making the device walk step by step.
  • walking devices which substantially comprise a frame for supporting the patient, to the bottom of whose support base two feet are integral, the lower surface of which slopes to form a dihedral angle, with its point towards the inside and its opening towards the side of the base plate.
  • the user proceeds by imparting to the apparatus a movement which combines an oscillation around a horizontal, longitudinal axis and a rotation around the vertical axis of his trunk.
  • the aim of the present invention is to obtain movements similar to those of a person walking, by means of a simple versatile device.
  • the device comprises two leg elements, linked together at an upper location in an oscillating way round a substantially horizontal axis; this linkage or connection can consist of a single pin around which the legs can rotate, or of two coaxial pins fastened in turn by a rigid structure or linked by an interposed mechanism.
  • Each leg ends at the bottom with a foot integral with it, which has a support surface at the bottom, which is usually relatively wide and is arched in the longitudinal direction (that is in the moving forward direction) and in the transverse direction.
  • the centre of gravity of the whole toy or, in the case of a therapeutic aid, by the aid plus the patient, is located below the pivoting axis.
  • the device is moved by imparting to it an oscillating movement in a transverse direction, substantially an oscillation around a longitudinal axis, in such a way as to disengage first one foot and then the other alternatively from the support surface; and a traction or thrust movement substantially in the direction for moving where it is desired to go.
  • the new device realizes in a simple way a walking movement relatively similar to that of a human being moving forward. It can be realized as an aid for paraplegics, as a piece of sports equipment, as a toy, as a gadget or as a robot for use in industry or for transport.
  • a first exemplary embodiment of the device is shown as a whole with 10 and comprises a pair of leg elements, respectively 12 and 14, linked together in an upper position, in the example by means of a single pin 16 with horizontal axis a , around which they can rotate.
  • Each leg is rigidly integral at its lower end with a foot part, respectively 18, 20.
  • Each foot part has a relatively wide bottom surface 18', 20', which serves as a support, and has an arched shape both on a longitudinal plane (that is on a plane extending in the direction of movement - arrow F - that is on the plane shown in figure 2) and on planes transverse to the said longitudinal plane (that is on the plane shown in figure 1 and parallel to it).
  • the word "arched” is used to indicate a curve which is not necessarily a circumference arc (respectively, not necessarily like a spherical cap), but any curve whatsoever. It should also be noted that the curve of the support surface of the feet can have a different radius in longitudinal section and in transverse section. It is appropriate, however, that the two lower surfaces 18', 20' should be symmetrical mirror images and it is preferable that, at least near the symmetry plane, the longitudinal curve should have a circular profile with its centre on the axis a .
  • an arm 25 is mounted in a rotating way on the pin 16, said arm carrying a weight 26 at its end.
  • the arm 25 can be rigid with an articulated joint on the axis a which allows only rotation, or of the spherical type with the possibility of transverse oscillation, possibly limited by an elastic device.
  • the arm 25 can also be of the flexible type, consisting of an elastic rod or a wire, and it is used to arrange the weight 26 in an appropriate position so that the centre of gravity of the assembly is at a desired level below the axis a .
  • FIG 1 a roughly anthropomorphic shell 28 is drawn with a broken line, such as could be used to realize the device in toy form.
  • the arm 25 may be omitted, the weight consisting of or being carried by the shell 28.
  • the device can move in various ways, for example: it can be placed on a surface sloping downwards and a slight transverse oscillation can be imparted to it, which is sufficient to release one foot after the other alternatively.
  • traction can be applied to the device, on a surface sloping upwards or downwards or horizontal, for example by means of a wire applied to the rod 25 or to the weight 26, and a transverse oscillation will be imparted to the device itself as for the previous case. It can also be moved with an internal source of energy, for example with the user's hands.
  • an additional bond for the legs consists in the fact that they have slots 30, 32 through which a transverse rod 34 is positioned in a loose way, said rod integral with the weight 36 to be carried, by means of an arm 35.
  • the arm 35 is idle on the pin 16, as the arm 25 is in the previous embodiment.
  • FIG 6 a further embodiment is shown with 200 and it is similar to the one illustrated in the figures 4 and 5, with a weight 36 to be carried in a position above the axis a , except that the additional bond between the leg elements 12, 14 consists of a crown wheel 40 which meshes with two pinions 42, 44, each one integral with a respective leg 12, 14, and idle on the pin 16.
  • Figure 7 illustrates an embodiment of the device as an aid for paraplegics or as a sports implement.
  • the device is indicated as a whole with reference number 300 and essentially comprises a support framework 302, in the shape of a box for example, carried on two substantially vertical leg elements 312 and 314, both of which are pivoted with pins 326 and 328 outside on the walls 303 and 304 of the box framework 302 around one and the same axis a .
  • each leg ends at the bottom in a foot, respectively 318, 320, whose lower support surface is curved both in a backwards and forwards direction and in a transverse direction.
  • Each leg 312, 314 is also provided with a means for determining and controlling the movement which, merely for the sake of example, has been illustrated as a hand grip 322, 324 respectively, but can consist of hand grips 322', 324' or some other.
  • the frame 302 has, in addition, a support base 306 for the user's feet and possibly a resting or abutment surface 308 to avoid bending of the knees.
  • the user suitably fastened to the device 300 by means not shown, by moving his head and/or shoulder imparts a transverse oscillation (makes the axis a oscillate around a longitudinal axis) in such a way as to weight and release one foot after the other alternatively, and he acts manually on the moving means relating to the momentarily released foot and, usually, also on the one supported.
  • box framework 302 can be suspended on the axis a by means of the interposition of elastic suspensions; the alignment of the pins 326, 328 must be ensured in such a case with a rigid additional structure.
  • the further embodiment in figures 9 and 10 is shown with 500.
  • the feet 518 and 520 are rigidly integral with the legs 512 and 514 respectively, and each of these carries, on each side, three wheels positioned offset 515, 516, 517; in all, each leg is provided with three wheels on each side, the homologous wheels being coaxial and preferably pivoted on the same pin, that is to say, preferably 516 is coaxial with 516', 516'' and 516'' etc.
  • the three wheels 515, 516, 517 are engaged in a sliding way on a semicircular track 521, integral with a side wall 522 of a body 524.
  • the wheels 515', 516', 517' of the leg 514 and the wheels 515'', 516'', 517'' of leg 512 are engaged with and run on opposite edges of a track 526 which is integral with the intermediate wall 528 of the body 525.
  • the wheels 515'', 516'', 517'' are engaged with and run on the edges of the track 536 shaped as part of a circle which is integral with the side wall 532, fixed in its turn to the plate 525 of the body.
  • the body 524 obviously can be of any shape whatsoever.
  • brackets 534, 536 a structure can be fixed with a seat, of the rocking-horse type or the like, for its use as a toy; or a so-called support 'cage' (figure 11) can be fixed to the body 524 for its use as an aid for paraplegics or as a piece of sports equipment.
  • the feet 518, 520 are curved in the forwards and backwards directions (a vertical longitudinal section shows a curve having the shape of part of a circle) and in the transverse direction (a transverse section shows a curve with the shape of an arc of a circle).
  • the device 500 works in the same way as the above devices; that is to say, by imparting to it thrust or traction in a longitudinal direction, as is illustrated with the arrow in figure 10, and a transverse oscillation in the said direction, the foot which is in the raised position slides along the track in the direction of the thrust, then it is subsequently rested and the other foot is lifted, which proceeds in the same way, and so on.
  • the rotation axis a for the feet in this case, is the axis of the cylinder defined by the tracks 520, 526, 530.
  • figure 10 offers the advantage of particularly small vertical dimensions.
  • the embodiment in figure 10 can be used as the base for an aid for paraplegics or as a piece of sports equipment. With respect to the embodiment in figure 7, it would offer the following advantages:

  • Electrotherapy Devices (AREA)
  • Measuring Pulse, Heart Rate, Blood Pressure Or Blood Flow (AREA)
  • Rehabilitation Tools (AREA)
  • Portable Nailing Machines And Staplers (AREA)
