Definitions

  • the present invention relates to an apparatus for returning balloons, in particular medacine balls, and it relates to an apparatus intended both for individual training, without a partner, and for exercises and group games bringing together several users, which allows throws that differ from those made directly between partners, in that each participant moves continuously, either to jump towards the device to throw the ball with increased force by momentum that he can take, either to place himself quickly in the return axis and catch up after his rebound, the ball previously thrown by another player.
  • This device which is currently on the market .
  • under the brand "PUNCH-BACK” includes a rectangular metal frame, each of the four sides of which comprises, around its own longitudinal axis, at least one longitudinal articulation, that is to say an articulation whose axis of rotation coincides with the longitudinal axis of said side and the effect of which, combined with the simultaneous effects of each of the other three longitudinal joints on the other three sides, gives said frame a capacity for warping in both directions, on either side of its intermediate plane position .
  • An elastic surface intended for return of balloons is constituted by an inextensible central net stretched elastically between the sides of the frame by means of bungee cords. This frame provided with its elastic surface will be referred to hereinafter as a reference frame.
  • a lateral element in the opening of which is engaged, along their common longitudinal axis, an extension whose penetration is limited, when the device is deployed in its position of use, by an internal stop constituted by a removable stop pin traversing transversely., from side to side, said lateral tubular element through two opposite orifices provided in its wall, each of the two extensions constituting in this position, a straight coaxial extension of the lateral tubular element in which it is engaged.
  • the two extensions are respectively mounted for rotation on a rear transverse element by means of two cylindrical sleeves respectively located near the ends and around the longitudinal axis of said rear transverse element, around which each of said sleeves forms a longitudinal articulation and to which said extensions are respectively welded perpendicularly.
  • Each of the extensions is retained in the lateral tubular element inside which it is engaged, by means of a bungee cord stretched between an outer end of said stop pin and the rear transverse element.
  • the removable assembly thus formed keeps the end of the extension pressed against said stop pin and forms a removable longitudinal articulation allowing said extension and said lateral tubular element to move. of rotation relative to each other about their common longitudinal axis.

  • a stop 35 intended to prevent the angular displacement of the element 26 relative to the element 23 beyond 180 ° from the folded position.
  • the stop 35 is constituted in the example of Fig. 1 to 4 by a metal tab welded to the element 23 and the free end of which protrudes towards the element 26 and thus ensures the rotation blocking of the extension 29 relative to the element 23 in the deployed position of the support frame.
  • An elastic return tensioner 36 in the middle of which is attached a fixing chain 37 which can be fixed to the ground by a stake 38, is stretched between the stops 35 of the elements 23.
  • On the sides 5 and 13 of the support frame 12 are mounted with thick rubber rings 39 forming supports for supporting the device on the ground.
  • the device When the device is placed on the ground for its use, it must be leaned, via the side 13 of its support frame 12, against an irreplaceable obstacle such as the bottom of a wall, a step or some other similar elevation of the ground and the tensions of the elastic tensioner 36 stretched between the stops 35 of the elements 23 and of the fixing chain 37, attached to the elastic tensioner 36 and fixed to the stake 38, which is preferably placed forward and near the side 13, help keep the device firmly wedged against the obstacle against which it is leaning.
