Shoulder pitch and arm adjustment for power box awning

Abstract

An awning mounted on a wall surface includes a rack, a canopy, a plurality of arms and a shoulder. The shoulder is configured to connect at least one proximal end of the arms to the rack and includes a bracket portion and a junction portion. The bracket portion includes a first curved surface. The junction portion includes a second curved surface shaped to correspond to the first curved surface. The first curved surface includes one of an elongate bead or a set of grooves. The second curved surface includes the other of the elongate bead or the set of grooves. The elongate bead is configured to fit within at least two of the grooves thereby allowing the junction portion to assume at least two orientations with respect to the bracket portion the junction portion is movably adjustable around a first axis.

 a rack;   a canopy;   a plurality of arms configured to support the canopy, each of the arms including a proximal end and a distal end, the distal end of each of the arms configured to move to and from the rack so as to retract and extend the canopy; and   a shoulder configured to connect at least one of the proximal ends of the arms to the rack, the shoulder including a bracket portion and a junction portion, the bracket portion including a first curved surface, the junction portion including a second curved surface shaped to correspond to the first curved surface, the first curved surface including one of an elongate bead or a set of grooves, the second curved surface including the other of the elongate bead or the set of grooves, the elongate bead configured to fit within at least two of the grooves thereby allowing the junction portion to assume at least two orientations with respect to the bracket portion such that the junction portion is movably adjustable around a first axis.   
     
     
         2 . The awning of  claim 1 , wherein the first curved surface is a cylindrical concave surface and the second curved surface is a cylindrical convex surface. 
     
     
         3 . The awning of  claim 1 , the shoulder further including a fastening component configured to secure the junction portion against the bracket portion so as to maintain the junction portion in the at least two orientations. 
     
     
         4 . The awning of  claim 3 , the junction portion including a recess opposite the second curved surface, the fastening component perimetrically dimensioned so to be at least partially insertable inside the recess. 
     
     
         5 . The awning of  claim 4 , the recess being substantially semi-cylindrical in shape, the fastening component being perimetrically rectangular. 
     
     
         6 . The awning of  claim 3 , a set of first holes extending through the fastening component, a set of second holes extending through the junction portion, a set of first screws configured to extend through the first holes and the second holes and into the bracket portion. 
     
     
         7 . The awning of  claim 6 , the set of second holes having an elongate cross-section and oriented to extend transversely with respect to the elongate bead, the first screws being insertable along any part of the second holes. 
     
     
         8 . The awning of  claim 6 , the junction portion capable of changing orientation around the first axis upon loosening of the first screws. 
     
     
         9 . The awning of  claim 1 , the shoulder configured such that the bracket portion is rotatably adjustable about a second axis that is perpendicular to the first axis. 
     
     
         10 . The awning of  claim 9 , the shoulder further including a base portion on which the bracket portion is movably mounted, the base portion configured to support the bracket portion from underneath. 
     
     
         11 . The awning of  claim 10 , the bracket portion including a third hole with a circular cross-section and a fourth hole with an elongate cross-section extending through the bracket portion, a set of second screws configured to be inserted through the third hole and the fourth hole and into the base portion thereby securing the bracket portion about the base portion, the second axis extending through a center of the third hole. 
     
     
         12 . The awning of  claim 10 , the base portion including an adjustment hole threaded to accommodate an adjustment screw, the adjustment screw configured to control a degree to which the bracket portion is rotatably adjusted around the second axis. 
     
     
         13 . The awning of  claim 11 , the junction portion including a hinge at a longitudinal end located opposite the third hole, the arm being rotatable around a third axis that is perpendicular to the first axis. 
     
     
         14 . The awning of  claim 1 , the rack including a channel in which the arm corresponding to the shoulder can be stowed, the arm extending substantially parallel to the first axis in a stowed position of the awning. 
     
     
         15 . The awning of  claim 14 , the arm being bendable at an intermediate portion so as to bring the awning to the stowed position. 
     
     
         16 . The awning of  claim 1 , the shoulder configured to be affixed at various positions along the rack. 
     
     
         17 . An awning mounted on a wall surface, the awning including:
 a rack;   a canopy;   a plurality of arms configured to support the canopy, each of the arms including a proximal end and a distal end, the distal end of each of the arms configured to move to and from the rack so as to retract and extend the canopy; and   a shoulder configured to connect at least one of the proximal ends of the arms to the rack, the shoulder including a base portion and a bracket portion supported from underneath by the base portion, the bracket portion being rotatably adjustable with respect to the base portion about a second axis extending perpendicularly about a plane of interface of the bracket portion and the base portion.   
     
     
         18 . The awning of  claim 17 , the base portion including an adjustment hole threaded to accommodate an adjustment screw, the adjustment screw configured to control a degree to which the bracket portion is rotatably adjusted around the second axis. 
     
     
         19 . The awning of  claim 17 , the bracket portion including a third hole with a circular cross-section and a fourth hole with an elongate cross-section extending through the bracket portion, a set of second screws configured to be inserted through the third hole and the fourth hole and into the base portion thereby securing the bracket portion about the base portion, the second axis extending through a center of the third hole, the bracket portion being rotatably adjustable about the base portion upon loosening of the second screws.
