Covering comprising cover plates clamped to profiles

Abstract

Covering that has a structure formed by multiple covering plates fixed by means of fasteners to longitudinal profiles each of which has a groove, the fasteners being located in the areas between the plates and the profiles of the guides, being simultaneously located within the cavities of the guide of the profiles and in a corresponding lodging of the plate, formed by a groove located in the side or lateral portion of the plate, fixing each fastener two contiguous plates and a profile, the fastener having dimensions that allow it to be turned in two positions when it is introduced in said guide, the fastener having at the same time an asymmetrical arrangement, in such a way that one of the rotation positions, that corresponds with the assembly position, the fastener enters in dimensional interference with the mentioned guide.

1 . A covering comprising:
 covering plates,   fasteners and   longitudinal profiles,   wherein: each profile is provided with a guide which is configured to cooperate with respective fasteners,   the guide comprises a groove that gives access to a cavity of greater dimensions, in cross section, than the groove,   a lateral edge of each plate is provided with a second groove,   each fastener is configured to cooperate with the second groove to clamp the plate to the profile, characterized in   each fastener has dimensions which permit a rotation between a first position and a second position when the fastener is lodged within said guide, and   each fastener comprises a first shape in a first crosscut and a second shape in a second crosscut, while the second shape of the fastener enters in dimensional interference with said guide in the second position and the first shape of the fastener is in the first position displaceable along the profile.   
     
     
         2 . The covering, according to  claim 1 , wherein the first crosscut is essentially perpendicular to the second crosscut. 
     
     
         3 . The covering according to  claim 1 , wherein the fastener is made of an injection moulded polymer of PA (nylon), POM, PC, PP, PET or PE. 
     
     
         4 . The covering, according to  claim 1 , wherein:
 each fastener comprises a head, a first neck adjacent to the head former, and a second neck adjacent to the first neck and a base adjacent to the second neck, and   the second neck and the base being aimed at being introduced, are disposed within the groove and the cavity, respectively, of said guide.   
     
     
         5 . The covering, according to  claim 4 , wherein a maximum width of the base in the first crosscut is essentially the same or smaller than a width of the groove, allowing the base to be introduced into the cavity through the groove. 
     
     
         6 . The covering, according to  claim 4 , wherein a width of the second neck in the first crosscut is essentially the same as a width of the groove, and each fastener is configured to be guided by cooperating guiding surfaces of the second neck and the groove, respectively. 
     
     
         7 . The covering, according to  claim 6 , wherein the width of the second neck in the first crosscut is in the range of about 90% to about 100% of the width of the groove. 
     
     
         8 . The covering, according to  claim 4 , wherein said dimensional interference comprises cooperating between a first surface of the cavity and a second surface of the base. 
     
     
         9 . The covering, according to  claim 8 , wherein said first surface of the cavity is adjacent to the groove. 
     
     
         10 . The covering, according to  claim 4 , wherein said dimensional interference comprises cooperating between a third surface of the groove and a fourth surface of the second neck. 
     
     
         11 . The covering, according to  claim 10 , wherein said third surface of the groove is adjacent to the cavity. 
     
     
         12 . The covering, according to  claim 4 , wherein a thickness of material of the profile at the groove is greater than the distance between the first neck and the base in order to obtain said dimensional interference. 
     
     
         13 . The covering, according to  claim 1 , wherein said dimensional interference is obtained between the fastener and opposite lateral walls of the guide. 
     
     
         14 . The covering, according to  claim 1 , wherein adjacent plates present an arrangement of protrusions and recesses conjugated to each other. 
     
     
         15 . The covering, according to  claim 1 , wherein a gap is provided between two adjacent plates in an assembled position. 
     
     
         16 . The covering according to  claim 3 , wherein the fastener is reinforced by glass fibre, Kevlar fibre, carbon fibre, talk or chalk.
