Portable carriage-table set

Abstract

A portable carriage-table set having a table including an upper surface, a lower surface, and a perimetric edge is provided. The lower surface of the table includes a stop and at least one hinge. The assembly can adopt a folded, transport carriage, transport carriage support, or table configuration. The portable carriage-table set further includes a first pair of bars which are, at one of their ends, respectively and pivotally coupled to the at least one hinge, and at the other end thereof they are joined together by means of an axis on which two wheels are respectively mounted in a rotary manner. A second pair of bars is housed within the space delimited by the first pair of bars, and a third pair of bars is positioned above the first pair of bars. A fourth pair of bars is positioned under the second pair of bars.

1 . A portable carriage-table set, comprising:

       2 . The set according to  claim 1 , wherein said first pair of bars is parallel to said table when said set adopts the folded configuration, the transport carriage configuration o the transport carriage support one, or forms an angle a with respect to said table when said set adopts the table configuration. 
   
   
       3 . The set according to  claim 1 , wherein said second pair of bars is parallel to said table when said set adopts the folded configuration, the transport carriage configuration o the transport carriage support one, or forms an angle a with respect to said table when said set adopts the table configuration. 
   
   
       4 . The set according to  claim 3 , wherein said angle a is substantially acute. 
   
   
       5 . The set according to  claim 1 , wherein said cross-piece is telescopically displaced outwards from said one of the ends of said second pair of bars when said set adopts the transport carriage configuration or the transport carriage support configuration, said first cross-piece being provided with first locking means for height adjustment thereof. 
   
   
       6 . The set according to  claim 1 , wherein said first transverse bar is positioned above said axis when said set adopts the folded configuration, the transport carriage configuration, or the transport carriage support one; or rests on said stop of said table when said set adopts the table configuration. 
   
   
       7 . The set according to  claim 1 , wherein said third pair of bars is parallel to said first pair of bars when said set adopts the folded or table configuration or forms an angle b with respect to said first pair of bars when said set adopts the transport carriage configuration, or that of transport carriage support. 
   
   
       8 . The set according to  claim 1 , wherein said fourth pair of bars is parallel to said second pair of bars when said set adopts the folded configuration, or forms an angle g with respect to said second pair of bars when said set adopts the transport carriage configuration, the transport carriage support configuration or the table configuration. 
   
   
       9 . The set according to  claim 7 , wherein angles b and g formed by said third and fourth pair of bars with said first and second pair of bars respectively, measure substantially 90°. 
   
   
       10 . The set according to  claim 1 , wherein said third transverse bar is positioned under said axis when said set adopts the folded, table or transport carriage configuration, or rests on the floor when said set adopts the transport carriage support configuration. 
   
   
       11 . The set according to  claim 1 , wherein bars of said first, second, third and fourth pairs of bars are substantially parallel among them. 
   
   
       12 . The set according to  claim 1 , wherein said second transverse bar is attached to said other of the ends thereof. 
   
   
       13 . The set according to  claim 1 , wherein said second transverse bar adopts the form of a second cross-piece telescopically coupled to said third pair of bars, said second cross-piece being provided with second locking means for the adjustment of the height thereof. 
   
   
       14 . The set according to  claim 1 , wherein said third transverse bar is attached to said other of the ends thereof. 
   
   
       15 . The set according to  claim 1 , wherein said third transverse bar adopts the form of a third cross-piece telescopically coupled to said fourth pair of bars, said third cross-piece being provided with third locking means for the adjustment of the height thereof. 
   
   
       16 . The set according to  claim 1 , wherein said table has a central opening for the insertion of a solar protection member, for example a sunshade.
