Definitions

  • the present invention relates to a folding device which makes it possible to place a buttock, the ipsilateral thigh, the contralateral gluteal fold and to improve the balance when using the lowered posture with a knee placed on the floor.
  • the existing devices do not allow the user to vary and choose the position of the ground support points of the device regardless of the orientation of the buttock and thigh in support for the center of gravity of the individual projects itself into the support polygon of the device.
  • the device according to the invention overcomes these disadvantages.
  • the device according to the invention can be folded by folding over the parts that compose it to reduce its volume for transport and storage. It also improves the balance by allowing to orient the support polygon of the device whose rectangular shape is related to the assembly configuration and the inclined positions of the elongated rigid parts that constitute this support. Free to rotate in a horizontal plane, the user can orientate the support consisting of the articulated assembly of three parts relative to a fourth part, to position it so that its center of gravity is always projected inside the polygon levitation of the device, regardless of the position of the bust of the user. It reduces the pressure on the knee in the lowered position with one knee on the ground.
  • the device consists of four parts (1), (2), (3) and (9), three of which have a substantially identical shape and dimensions (1), (2), (3) articulated to a fourth portion (9) which is a truncated pyramid-shaped solid.
  • Parts (1), (2) and (3) have an elongated shape with a straight end and a symmetrically enlarged base in the same plane.
  • the part (9) which supports the part (1) is itself supported by the other two parts (2) and (3) with which it is secured at their ends by articulations (5) and (6) constituting and a support whose ground supports consisting of the bases (7) and (8) are wide and spaced to provide a rectangular shape to the support polygon.
  • the portion (1) is articulated at its base with the upper face of the portion (9) to receive at this level a buttock and contralateral crease under the flange at the level of enlargement.
  • the portions (2) and (3) arranged in support are hinged with the part (9) respectively with a side face (10) and its underside (11).
  • the part (1) pivots on the part (9) along an axis (4) perpendicular to the upper face thereof, thus providing the possibility of positioning the ground supports that are the bases of the parts (2) and (3) support consisting of parts (2), (3) and (9) as desired by the user to ensure depending on the orientation of the bust a projection of the center of gravity of the individual closer to the center of the polygon of lift.
  • the device is unfolded by removing the bases of the parts (2) and (3), its height is maintained by any means avoiding a separation of the parts (2) and (3) and passing through the holes (12) and (13) .
  • the two parts (2) and (3) fold vertically by gravity during the lifting of the device.
  • the user then tilts the part (9) by 90 ° to bring down its lateral face (10) articulated with the part (2), and thus laterally bring the articulated lower face (11) with the part (3), the part (1) is then in a plane substantially parallel to the plane of the part (2).
  • the axis of rotation perpendicular to the upper face of the portion (9) rotates the portion (1) to be superimposed on the portion (2).
  • Parts (1), (2) and (3) are thus superimposed, thereby reducing the volume of the device for its transport and storage.
  • a solid segment of trapezoidal section (15) can be added near the end of the part (1) on its underside can thus be used to support the calf of the front leg of the user.
  • the constituent parts of the device (1), (2), (3), (9) and (15) can be made of light and hard materials.
  • the articulation between the portion (9) and the portion (2) is a hinge fixed on the side face of the portion (9) and on the inner face of the portion (2) near its end.
  • the articulation between the portion (9) and the portion (3) is a hinge fixed on the underside of the portion (9) and on the inner face of the portion (3) near its end.
  • a closed strap through the holes (12) and (13) can fight against a larger gap that causes the weight of the user.
  • the lower edges of the bases of the parts (2) and (3) may have a concave shape downwards, and the upper edges of the bases may have convex shapes upwards.
  • the parts (1), (2) and (3) will have a length of 40 cm, widths of 12 cm for the end and 28 cm for the base.
  • the device according to the invention is particularly intended for ground activities, it brings greater comfort to the user.
