Bower, characterized in that the truss is provided with a roof frame ( 6 ) over part of its width, under which are provided two rollers ( 10 A and 10 B) extending in the longitudinal direction of the bower, and on which is wound a cloth which can be laterally unwound over the remaining part of the truss and which can be further guided downward over a return pulley ( 14 A, 14 B) at the top far end of the posts ( 3 A- 3 B) up to the foot of the posts ( 3 A- 3 B).

1 - 10 . (canceled) 
   
   
       11 . A bower comprising a frame having at least four posts having top ends and bottom ends, said posts connected lengthwise in pairs by means of longitudinal joists extending in the longitudinal direction, and which joists are connected in pairs by means of two transverse trusses which are each formed of slanting joists which are connected at their proximal ends so as to form an angle with each other, wherein each truss extends over a part of the width of a roof frame under which are provided two rollers extending in a longitudinal direction and on each of which is wound an upper cloth which is extendible by unwinding the cloth over a remaining width of the truss and downwardly over a return pulley extending between the top ends of a pair of lengthwise spaced posts down to the bottom ends of the pair of posts. 
   
   
       12 . The bower according to  claim 11 , comprising a housing having an upwardly opening longitudinal slot and extending in a transverse direction at one far end of the bower, said housing connecting a pair of transversely spaced posts at a far end of the bower, said housing containing a roller extending in the longitudinal direction of the housing on which is wound a lower cloth which is accessible via the slot between the pair of posts up to a bottom side of the roof frame. 
   
   
       13 . The bower according to claim  1 , wherein the rollers are provided with a return spring which is tensioned by unwinding the respective cloth so as to cause said cloth to be rewound under the influence of the built-up spring tension when the cloth is released while in an unwound condition. 
   
   
       14 . The bower according to  claim 11 , including a lock securing each cloth in an unwound condition. 
   
   
       15 . The bower according to  claim 14 , wherein the lock is formed of hooks around which an unwound cloth can be hooked, or of a reel system. 
   
   
       16 . The bower according to  claim 11 , wherein the roof frame is provided with a bottom extending up to a distance from the roof frame so as to form a slot through which a cloth can extend and be unwound. 
   
   
       17 . The bower according to  claim 16 , wherein the cloth is provided with a lath on its free end whose cross section is larger than the opening formed by the slot. 
   
   
       18 . The bower according to  claim 11 , wherein the cloth has side edges, and wherein the posts and the joists are formed of L-shaped struts whose legs are directed outward so as to cover the side edges of the unrolled cloth. 
   
   
       19 . The bower according to  claim 11 , wherein the free end of the lower cloth which is extendible upwardly has the shape of the lower side of the respective truss as a whole, and in that the roof frame is trapezoidal. 
   
   
       20 . The bower according to  claim 11 , wherein support elements are provided in the roof frame to support or mount lamps, decorations, or acoustic devices.
