Definitions

  • the present invention relates to a blade attachment system for mount side by side of the blades so as to create a perforated structure.
  • the blades are parallel to each other at an angle to the wall on which they are installed.
  • Such blades are used in particular to form ventilation grilles closing a bay in a wall or for making siding walls of buildings.
  • the blades are maintained at interior of a frame mounted in the bay while in the case of a wall facing, the blades are placed on the fastening system and placed end to end to cover the Wall.
  • stiffening profiles often made of aluminum, have been used until now. support elements to be mounted on the stiffening profiles.
  • a known technique is to use stiffening profiles in which fixing notches are machined for the fixing the support elements. Therefore, each support element has a location well determined on the stiffener profile.
  • GB-2,300,473 discloses a system comprising a stiffening profile with a rail, support members slidably engaged in the rail of the profile stiffener and blades attached to the support members.
  • Sliding support in the rail of the profile is provided by a skate portion which is engaged in the rail. This part therefore serves as retaining means for the support element in the rail of the profile.
  • the preamble of claim 1 is also based on this document.
  • the skate part is directly part of integral part of the support element. Indeed, the skate part forms a kind of sole of trapezoidal section from which extend the other flanges of the element of support. It is therefore quite impossible to separate the skate part from the rest of the support element.
  • EP-0 770 832 describes a completely different type of grid, since the blades are inserted in the rail formed by the profile. However, as in the previous document, the part of the blade support means which are inserted into the rail are an integral part of the support means.
  • the present invention aims to overcome the aforementioned drawbacks of the art prior art by defining a more flexible fastening system with which the elements of Support can be easily and quickly set up in the stiffener profile.
  • the present invention provides a blade attachment system comprising the features set forth in claim 1.
  • the characterizing portion of claim 1 stipulates that the support elements are provided with means of receiving adapted to receive the retaining members. This directly implies that retainers are not an integral part of the support elements but, on the contrary, they constitute separate elements reported in the reception means formed by the support elements. In other words, the retainers are mounted on the elements support at the level of adequate reception means.
  • This feature allows the embodiment defined in a dependent claim, namely that the elements can be inserted into the rail without the retainers that can be subsequently mounted on the support elements already engaged in the rail. This allows to insert the support elements into the rail directly through the longitudinal opening and not from one end of the rail. This possibility of mounting elements in the rail is made possible by the fact that the retaining members are parts separated from the support elements.
  • the support members are slidably mounted in the rail. This confers on fixing system a very great flexibility that facilitates and accelerates the installation such blades.
  • the base of the wall is not perfectly level, that is to say horizontal, just fix the stiffening elements against this wall with the lower end of the stiffeners in contact from the ground that is not level, then adjust the first row of support elements to level.
  • This first row of support elements at the level will serve as a basis for other support elements that will be engaged in contact with this first row. We see therefore it is not necessary to adjust the position of the stiffeners as that the support elements can be fixed at any point of their length.
  • the longitudinal rail forms two grooves longitudinal sides open towards each other.
  • the organs of restraint consist of rods whose ends are respectively engaged in the lateral grooves.
  • the support elements comprise several housing adapted to receive a rod as mentioned above.
  • At least one dwelling is designed to allow the reception of a rod by lateral introduction on the length of the housing, thus allowing the establishment of the rod while the element of support is already engaged in the longitudinal rail of the stiffening element.
  • least one housing is designed to allow the reception of a rod by sliding introduction from an open end of the housing, so that the element of support can be engaged in the longitudinal rail of the stiffening element only by a end of it.
  • the present invention also relates to a grid and a wall cladding implementing such a blade attachment system.
  • the blade attachment system comprises, in addition to two types of component parts, namely a stiffener element 1 and elements 2. All the support elements 2 can be identical and cooperate with the stiffening element 1 in the same way. Support elements 2 include fastening means for blades 3. Each support element 2 receives a blade 3. In summary, the support elements 2 are integral with the stiffening element 1 and support the blades 3.
  • the stiffening elements 1 may be in the form of a profile in aluminum.
  • the aluminum profile has a longitudinal configuration such as a closed off.
  • the stiffener profile 1 comprises a base 11 intended to bear against a surface, for example a wall when it is a question of facade cladding. In the case of a grid, this base 11 does not come into contact with any ventilation.
  • the stiffener profile 1 forms two branches 12 and 13 defining a longitudinal rail or channel between them.
  • the support elements 2 are engaged inside this longitudinal rail 14 in which they can freely slide.
  • the branches 12 and 13 form flanges 15 and 16 defining two longitudinal lateral grooves 17 and 18 whose openings face each other. These lateral grooves 17 and 18 are intended to receive retainers 27 secured to the support members 2.
  • the support members 2 can no longer be disengaged from the rail 14 by a simple pull on the support element 2 out of channel 14.
  • the support elements 2 comprise a base 21 intended to rest inside the rail 14. From this base 21 extend several appendages upwards, including fixation appendages 22, 23 and 24 which cooperate with a blade 3 so as to hold it firmly on the support element, as can be seen in Figure 2.
  • the support member forms a hook 22, a fulcrum 24 and a leg 23 which together define three points sufficient support to hold the blade securely.
  • the blades have substantially the shape of an S with a base portion 31 which cooperates with both the hook 22 and the fulcrum 24, a median inclined portion 32 and a curved end portion 33.
  • the blade forms a snap lug 34 intended to cooperate with the leg 23 of the support element 2.
  • the support elements 2 also form one or more housings for receiving retaining members 27 made in the form of rods, as can be seen more precisely in Figure 1. These rods extend across the housings 25 or 26 and penetrate with their respective ends 271 inside the lateral grooves 17 and 18 formed by the receiver profile 1 as can be seen in FIG. Thus, the support elements 2 are integral with the stiffener profile 1 while slidable inside the rail 14. It can be seen more precisely in FIG. each support member 2 is provided with a plurality of housings 25 and 26 for receiving a rod 27. There are two types of housing, namely dwellings 25 in which the rod 27 must be engaged by one end and the housing 26 in which the rod can be introduced along the length of the housing without being introduced by one end.
  • An engaged rod in a housing 25 does not allow to engage the support member 2 in the rail 14 being since the ends 271 of the rod prevent insertion into the grooves 17 and 18. In this case, it is necessary to engage the support element in the rail 14 by one of the stiffening profile ends 1. It is quite different with dwellings 26 which are open on their length, which allows a subsequent introduction of the rod. Indeed, he it is then possible to engage a support element inside the rail 14 and then to house a rod inside one of the two housing or the two housing 26 by introducing the bias rod and engaging its ends in the grooves 17 and 18 to finally come the to lodge inside one of the accommodations 26 by a translational movement in the direction longitudinal profile stiffener.
  • the stiffener profile 1 does not require subsequent machining and can therefore be used as is. Just cut it to the desired length.
  • the various elements of support 2 can be positioned anywhere on the profile length receiver 1, which gives great flexibility of use.
