Description

DESCRIPTION

  The present invention relates to the field of closure devices,

  in particular play areas and is intended to be a noise and anti-noise

  shock. The fence of play areas, in particular ball games or ball games, is generally made by means of fences stretched between support posts or hung on support posts, these screens having a

  mesh tight enough to prevent the passage of a ball.

  These screens are used simultaneously to prevent any

  unauthorized penetration into playgrounds.

  In addition, toasting boards are used on relatively large heights and widths behind the areas most in demand by a ball, namely football goals, basketball boards, handball goals, etc., in order to avoid the loss of balloons following the crossing of the fence

  or accidents caused by balloons crossing the fence.

  Existing grids, stretched on posts or hung in the form of panels on the posts, however, have the drawbacks of rapid degradation and / or a significant release of annoying noise both for

only for the neighborhood.

  Indeed, especially in the case of use of tight mesh, they deform rather quickly under the repeated impacts of bullets or balloons and undergo significant fatigue leading to degradation

requiring replacement.

  In the case of use of mesh panels, these are generally constituted by a grid welded in a frame and the repeated impact of bales has the consequence, on the one hand, a deformation of the mesh causing its tearing at the welds and, on the other hand, an important training of

noise due to shocks.

  Apart from nuisances inflicted in the vicinity, these existing fence elements also have the disadvantage of requiring

  continuous maintenance, which considerably increases the use.

  The present invention aims to overcome these disadvantages.

  Its purpose is indeed a noise-proof and anti-shock grill panel, comprising a frame for receiving a grill welded to said frame, characterized in that the frame for receiving the grill is mounted by means of a connection device -2- elastic in a fixing cage on vertical and / or horizontal support elements.

  The invention will be better understood, thanks to the following description, which

  relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the appended diagrammatic drawings, in which: FIG. 1 is an elevational view of a frame according to the invention, and FIG. FIG. 2 is a view on a larger scale of the detail A of the

figure 1.

  According to the invention and as shown more particularly, by way of example, Figure 1 of the accompanying drawings, the anti-noise and anti-shock mesh panel, which comprises a frame 1 for receiving a grid 2 welded to said frame 1, is characterized in that the frame 1 for receiving the mesh 2 is mounted by means of an elastic connection device 3 in a

  cage 4 for fixing on vertical and / or horizontal support elements.

  According to one characteristic of the invention, the elastic connection device 3 is constituted by a set of elastic studs secured at regular intervals with the frame 1 for receiving the mesh 2 and with the cage 4 for fixing on

  vertical and / or horizontal support elements.

  The elastic studs constituting the device 3 are, in known manner, pads of natural or synthetic rubber or of another material having the properties of rubber and are provided, on two opposite faces,

  a fastening element with a support or the like, such as a threaded rod.

  Thus, the connection between the frame 1 and the cage 4 is made with a possibility of deformation allowing a displacement of the frame 1 relative to the

cage 4.

  In order to allow a particularly easy assembly of the elastic studs forming the device 3, respectively on the frame 1 and on the cage 4, the frame 1 and the cage 4 are provided, at the level of the connections by said elastic studs, with parallel attachment surfaces. 1 'and 4', provided directly on the

  frame 1 or attached to the cage 4.

  According to another characteristic of the invention, the attachment surfaces 1 'or 4' of the frame 1 or the cage 4 are advantageously provided with a means 5 for protecting each elastic stud forming the elastic connection device 3, this means 5 extending entirely around each pad and being

  secured by welding or other with the corresponding surface 1 'or 4'.

  By way of example, this means 5 can simply be constituted by a tubular protection sleeve. Thus, it is possible to protect the elastic portion of each pad against deliberate shear in the context of acts of vandalism, said elastic portion becoming inaccessible to any cutting tool or other likely to degrade. The frame 1 for receiving the mesh 2 may be constituted by flat welded sections or by any other type of folded profiles, on

  which the mesh 2 is welded internally.

  Similarly, the cage 4 for fixing on vertical and / or horizontal support elements may also be constituted by a heat-welded assembly of flat sections, the fixing surface 4 'of the elastic connection device 3 being then an integral part of said cage 4, or in the form of a folded section, the fixing surfaces 4 'of the elastic connection device 3 then being provided at the level of

  each elastic stud forming said device 3.

  It follows from the foregoing that the grid panel according to the invention is of an extremely simple constitution allowing rapid assembly of the assembly while protecting the elastic connection against acts of vandalism. In the case of a shock due to the impact of a ball or a ball on the mesh 2, it reflects the shock wave on the frame 1 which tends to

  move in the direction followed by the ball or ball.

  It follows a transmission of a shear force through the anchoring of the pads forming the device 3 on the frame 1, this force being totally absorbed by the elastic portion of said pads fixed at their other end on the cage 4. The absorption of this shear effect has the consequence of avoiding a transmission of vibrations on the vertical supports

  and / or horizontal and, thereby, to allow a significant reduction of noise.

  In addition, because of the absorption of the shock wave in the form of a displacement of the entire frame 1 relative to the cage 4, the wires of the mesh 2 are subjected to a lower stress favoring better resistance against damage. any deformations. Indeed, the assembly according to the invention allows a

  shock absorption of the ball or other on the fence.

  Thanks to the invention, it is possible to produce a simple and easy-to-assemble anti-shock and anti-noise mesh panel,

returns relatively low.

  In addition, such a panel has a significantly increased longevity

  compared to existing grids.

  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention. -5-
