         2 . Structure and automatic blocking mechanism for awnings according to  claim 1 , characterized in that the automatic blocking mechanism employs a catch ( 60 ) with a simple longitudinal sliding slot ( 60   f ), wherein magnets ( 60   p,    60   n ) are furnished at the two and regions of the longitudinal sliding slot ( 60   f ), wherein the magnets ( 60   p,    60   n ) operate on the iron containing bearing bolt ( 6   e ) and wherein the same magnetic retaining effect can be obtained by magnetic bearing bolt ( 6   e ), wherein the bearing bolt operates on iron elements provided at the two end regions of the sliding slot ( 60   f ).  
     
     
         3 . Structure and automatic blocking mechanism for awnings, according to  claim 1 , characterized in that the profile tube of the carriage ( 2 ) carries on the front side in each case the bearing plate ( 4 ), wherein the bearing bolts ( 5   a ) for the track rollers project from the bearing plate ( 4 ) on the inside into the profile tube ( 2 ), while the bearing bolt ( 6   e ) for the catch ( 6 ) is possibly adjustable attached at the oppositely disposed side of the bearing plate, wherein the same bearing plate ( 4 ) exhibits at the upper side a flange ( 4   b ) for the supporting of the side edge of the awning material ( 3 ), wherein the lower face of the flange ( 4   b ) operates simultaneously as a limit stop for the catch ( 6 ) in locking position, wherein a vertical projection ( 4   c ) projects from the flange ( 4   b ) and wherein the bearing plate is continued downwardly in the lower area with an edge projecting out of the outer line of the cross section of the profile tube ( 2 ) of the carriage.  
     
     
         4 . Structure and automatic blocking mechanism for awnings according to claims  1  and  2 , characterized in that a possibly adjustable limit stop element for the catch ( 6 ) is attached in locking position below the flange ( 4   b ) or at the bearing plate ( 4 ).  
     
     
         5 . Structure and automatic blocking mechanism for awnings, according to  claim 1  characterized in that the track rollers are supported immediately at the profile tube ( 2 ) of the carriage.  
     
     
         6 . Structure and automatic blocking mechanism for awnings according to  claim 1  characterized in that the catch ( 6 ) is furnished with projections or notches at one or at two cross sides ( 6   k,    6   m ), in order to favor the engagement at one of the limit stop elements ( 7 ,  8 ,  4   b ) during the individual functional phases.  
     
     
         7 . Structure and automatic blocking mechanism for awnings according to  claim 1  characterized in that the track rollers ( 5 ) all or in part are adjustably supported.  
     
     
         8 . Structure and automatic blocking mechanism for awnings according to the preceding claims characterized in that also movable supports are running along the same running flanges ( 1   c ) for the carriage, which movable supports comprise substantially a tube ( 10 ) with bearing element ( 11 ) fixedly connected at the front side of the tube ( 10 ), wherein coaxial bearing bolts for rotatable track rollers ( 13 ) and support disks ( 14 ) project from the bearing elements ( 11 ), wherein the support disks are furnished with cylindrical coaxial projections ( 15 ) on the front face with progressively decreasing diameters ( 15   a,    15   b,    15   c,  and the like) and wherein adjustable limit stops ( 16   a,    16   b,  and the like) directed against the projections ( 15 ) during the moving out ( 2   a ) of the carriage ( 2 ) operates at the coaxial projections ( 15 ).
