Modular frame for paintings

Abstract

Modular frame for painting for displaying original paintings or photographic replicas from digital or plastic arts! Such paintings are usually marketed at museum stores, galleries and in stores related with art and decoration. The modular frame is composed of identical pieces, which form the frame once they are coupled. The pieces are fit in together in order to provide the shape of the frame and the paints or replicas are fixed by means of connecting means. The modular frame comprises mainly two types of pieces: tongue and groove connecting elements ( 1 a, 1 b ) and extension elements ( 2 ). The objective is to provide a frame which is easy to assemble and which accepts a canvas made to fit therein in an equally simplified manner.

1 . Modular structural mountable and demountable picture for displaying reproductions of digital images printed on canvas, comprising two parts: modular structural frame ( 1 , 2 , 3 ) and attachable canvas;
 wherein the modular structural frame comprises two types of components: connecting elements with dual variable fitting ( 1   a ,  1   b ) and extension elements ( 2 );   wherein the extension elements ( 2 ) create different sizes for the structural frame according to the number of extension elements ( 2 ) used;   wherein the extension elements ( 2 ) are provided with movable connecting means to fix the canvas ( 2 ).   wherein the connecting elements ( 1   a ,  1   b ) with dual variable fitting will connect the extension elements ( 2 ) with a 180° or a 90° angle, to widen the structure or to make a corner according to the chosen fitting option   wherein the connecting elements ( 1   a ,  1   b ) are linked by means of fitting in a groove connecting element ( 1   a ) into a tongue connecting element ( 1   b );   and the canvas is placed on the modular structural frame by movable connecting means.   
   
   
       2 . Modular structural according to  claim 1 , characterized in that the connecting elements, which join the canvas to the extension elements ( 2 ), consist of fixing two velcro faces, one being placed at the canvas' and surface and the other being placed on the extension elements ( 2 ). 
   
   
       3 . Modular structural according to  claim 1 , characterized in that the connecting elements, which join the canvas to the extension elements ( 2 ), consist of small pins placed in the extension elements ( 2 ) which fit in eyelets placed at the canvas' end. 
   
   
       4 . Modular structural according to  claim 1 , characterized in that the connecting elements, which join the canvas to the extension elements ( 2 ), consist of magnets placed at the canvas' end surface and a metallic surface placed on the extension elements ( 2 ). 
   
   
       5 . Modular structural according to  claim 2 , characterized in that the connecting elements, which join the canvas to the extension elements ( 2 ), are placed in an inner surface of the frame. 
   
   
       6 . Modular structural according to  claim 1 , characterized in that the extension elements ( 2 ) have a square profile and in that the connecting elements ( 1   a ,  1   b ) are separated from the extension elements to provide two types of connections (extension or corner), and have a part presenting a smaller square profile so that a tight fit with the extension elements ( 2 ) occurs even being demountable, and a part comprising a tongue and groove element. 
   
   
       7 . Modular structural according to  claim 6 , characterized in that the part of the connecting elements ( 1   a ,  1   b ) that comprises the tongue and groove elements, when fit in the extension elements ( 2 ), has a fitting face at a ±45° angle to the inner face of the extension element ( 2 ) in order to allow using the said connecting elements ( 1   a ,  1   b ) as corners or extensions of the frame's side element according to the chosen fitting option to the extension element. 
   
   
       8 . Modular structural according to  claim 1 , characterized in that the connecting elements ( 1   a ,  1   b ) consist of a groove element ( 1   a ) and a tongue element ( 1   b ) wherein the blob has a circular shape. 
   
   
       9 . Modular structural according to  claim 3 , characterized in that the connecting elements, which join the canvas to the extension elements ( 2 ), are placed in an inner surface of the frame. 
   
   
       10 . Modular structural according to  claim 4 , characterized in that the connecting elements, which join the canvas to the extension elements ( 2 ), are placed in an inner surface of the frame.
