ABSTRACT:
A pivotal hinge for an arm of an awning, wherein a supporting block is tightly clamped on a rectangular supporting tube and carries a pivotal bracket swingable and lockable about an axle disposed in parallel with the supporting tube. The pivotal hinge is adjustable in a simple manner by a readily available tool and has high stability, particularly rigidity against torsion. The supporting block is defined by a yoke including two legs joined by a central web, one leg being defined by two parallel webs and a cross web connecting same. A supporting trunnion is carried within a pair of eyes formed in spaced projections extending beyond the central web for pivotally supporting the pivotal bracket. A threaded sleeve is rotatably supported in a guide passage provided in the cross web, with a threaded bolt being engaged through the threaded sleeve and having one end pivotally connected to the pivotal bracket.
