Abstract

Ο πρόβολος (1) που μπορεί να στρέφεται γύρω από ένα οριζόντιο άξονα (3) έχει ένα κεντρικό διατεταγμένο υποστήριγμα (2). Οι εκτινόμενες παράλληλα προς τον άξονα στροφής (3) εγκάρσιες δοκοί (11...16) είναι διατεταγμένες αρθρωτά στο υποστήριγμα (2) και κάθε μία είναι συνδεδεμένη τόσο με ένα σημείο (21...26) του υποστηρίγματος (2) που βλέπει προς τα έξω από τον άξονα στροφής (3) μέσω ενός λοξώς διατεταγμένου σχοινίου με προκαθορισμένο μήκος (31,32,35,36,39,40), όπως επίσης με μια διάταξη τάνυσης (45,46) που μπορεί να στρέφεται γύρω από τον άξονα στροφής (3) μέσω ενός άλλου συνεχούς σχοινίου (33,34,37,38,41,42) που εκτείνεται παράλληλα προς το υποστήριγμα (2). ωThe cantilever (1) which can be turned about a horizontal axis (3) has a centrally arranged support (2). The transverse beams (11...16) projecting parallel to the turning axis (3) are hingedly arranged on the support (2) and each is connected to a point (21...26) of the support (2) facing outwardly from the turning axis (3) by means of an obliquely arranged rope of a predetermined length (31,32,35,36,39,40), as well as a tensioning device (45,46) which can be rotated about the pivot axis (3) by means of another continuous rope (33,34,37,38,41,42) extending parallel to the support (2). oh
