Definitions

  • the present invention relates to the field of devices for covering a surface.
  • the object of the invention finds particular application in all areas where a surface, defining a space, must be covered by a protective element such as a tarpaulin, a curtain or a leaf shutter.
  • the invention is adapted to cover the surface of a pool with a tarpaulin.
  • the patent EP 0 634 981 discloses a device for covering and uncovering a surface using a roll-up cover element such as a tarpaulin.
  • This device is made in the form of a gantry provided with means for moving the sheet above the surface such as a rigid chain pushing moving on either side of the surface. These chains are controlled in translation so as to push a head beam on which is mounted the cover.
  • the device is provided with a series of trolleys providing a temporary connection between the cover and the chains. These carts are intended to be distributed along the cover, when the latter covers the surface.
  • the device further comprises a system for separating the sheet from the chain at a store in the unclogging direction, for storage by retraction of the sheet relative to the chain.
  • Such a device offers the particular advantage of ensuring the sheeting and uncovering of the surface and allows to be completely retracted in unclogging position, prohibiting any deterioration in the open position.
  • the chains are completely retracted, which is a particularly advantageous advantage in the field of pools since the device does not require the presence of rails that are particularly unsightly and a source of danger for users.
  • such a device may have certain drawbacks, in the position of covering the surface, when particularly exceptional climatic conditions occur and in particular, strong wind squalls. Under these conditions, it may happen that some carts come off the chains, thus preventing the tarp from fully playing its role of covering. In addition to the fact that the tarpaulin does not cover properly the dedicated space, the replacement of trolleys on the chains is a relatively difficult operation to carry out. Moreover, as the chains do not have rails to guide them, the surfaces receiving them are not perfectly flat, so, it is possible that the covering of the swimming pool is unsatisfactory.
  • the present invention therefore aims to remedy these drawbacks by proposing a device for covering and unclamping a surface retracting in the unclogging position by completely releasing the surface and able to cover the surface by providing improved stability of the tarpaulin compared to the Prior Art.
  • the device according to the invention thus makes it possible to ensure the uncovering of the surface while being completely retracted, and by completely releasing the surface while improving the stability of the tarpaulin by preventing the wagons from being unhooked by the wind when the surface is covered.
  • the present invention proposes a new installation 1 for covering and removing a surface such as the surface of a swimming pool.
  • This new installation offers the aesthetic advantage of loosening the surface by retracting completely so as to disappear from the view of users.
  • Another advantage offered by the invention is to improve the stability, during the sheeting of the surface or when sheeted, compared to the already known installations.
  • the Fig. 1 illustrates in part an installation 1 according to the present invention, in that the installation as a whole is symmetrical to the illustration of the Fig. 1 .
  • the installation 1 comprises a head beam 2 on which is mounted or fixed a tarpaulin 3.
  • tarpaulin means any flexible or rigid means of occultation of the surface.
  • the cover 3 may be a flexible membrane or a juxtaposition of rigid panels, of materials commonly used by those skilled in the art.
  • the installation 1 comprises a chain 4, which is composed of a series of links 5 and which has the characteristic of being rigid in thrust, with one end connected to the beam of head to move the cover 3 between a magazine M receiving the cover 3 in the open position of the surface and a full covering position of the surface.
  • the chain 4 is controlled in displacement by a pinion 6.
  • the links 5 which will be more precisely described in the following description are arranged to firstly allow a relative pivoting between the links 5 in a given direction, for the return chains 4 in the magazine M and, on the other hand, prohibit such relative pivoting in the opposite direction so that the links 5 rest on each other so that the chains 4 become rigid in thrust when the sheeting operation.
  • the installation 1 thus comprises two chains 4, each positioned on either side of the sheet 3 so as to extend on two opposite sides of the surface to be covered. Consequently, the installation also comprises two pinions 6 each adapted to move one of the chains 4. Also, the two pinions 6 are connected in rotation by a connecting shaft (not shown).
  • a rotation of the pinions 6 is controlled by a motor 7 which is activated using an electrical control such as a push button, a remote control or a programmable cell.
  • the rotation of the pinions 6 causes the translation of the chains 4 is in a first direction said sheeting to cover the surface, or in a second direction opposite to the first sense of said débâchage to unclog the surface.
  • the installation 1 comprises, in addition, a series of supports or carriages 8 which provide a link between the cover 3 and the chains 4.
  • the carriages 8 are carried by sleepers 10 and, more precisely, by brackets 11 mounted at each end of the crosspieces 10.
  • the crosspieces 10 advantageously extend parallel to the head beam 2.
  • the crosspieces 10 consist of profiles hollow which will be described in the following description.
  • the brackets 11 are typically threaded into the hollow profiles of the 10.
  • the carriages 8 are carried two by two by a cross member 10 and two brackets 11, thus ensuring, during the translation of the carriages 4, the translation of the crosspieces 10 and 11 of the gallows parallel to the head beam 2.
  • the installation 1 comprises a system 9 of uncoupling the sheet 3 relative to the chains 4 acting at the input of the magazine M and at least in the direction of débâchage.
  • the uncoupling system 9 comprises a rail A centered on each direction of movement of the chains 4 to ensure the separation of the carriages 8 with respect to the chains 4 during the uncovering of the surface.
  • the system 9 ensures the fastening of the sheet 3 relative to the chains 4 in the direction of sheeting, as will be described in the following description.
  • the carriages 8 provide a temporary and relative connection between the carriages 4 and the cover 3.
  • each carriage 8 comprises, as illustrated in FIG. Fig. 2 , at least one clamp 12 adapted for the temporary gripping of a roll 13 of a link 5 of the chain 4 and a locking unit 14 of said gripping.
  • the roller 13 advantageously extends in a direction d perpendicular to the direction of the chain.
  • Each carriage 8 thus makes it possible to improve the stability of the installation 1 , in particular when the surface is covered. Indeed, the gripping of the roller 13 by the clamp 12 makes it possible to block the cover 3 vis-à-vis the chains 4 especially when it is subjected to gusts of wind.
