Abstract

Quadrangular connector for connecting mutually perpendicular surfaces, indicated by the fact that it includes four identical square rings (2,3,4,5) with a hole (11) on one of its sides, which are connected to each other in two horizontal and two vertical directions of one plane with four identical forks (1) in the shape of a stretched letter "u" and with a hole (10) on the right arm of the fork (1), in such a way that each of the four square rings (2,3,4,5) is wedged in the groove by its width ( 8), whose length corresponds to the width of the square ring (2,3,4,5), and which is located on the upper surface of the right arm of the fork (1), so that when pinching, the hole (10) of the fork (1) and the hole ( 11) of the clamped square hoop (2,3,4,5), while in the groove (9) located on the upper surface of the left arm of the same fork (1), the length of which also corresponds to the width of the square hoops (2,3,4 ,5), the clamped wall of the adjacent square hoop (2,3,4,5), so that in the clamping position the left arm of the fork (1) is always parallel to the axis of the corner (11) of the adjacent square hoop (2,3,4,5), where the adjacent square hoops (2,3,4,5) and the adjacent forks (1) are positioned so that the axes of the holes (11) of the adjacent hoops or axes the holes (10) of the adjacent forks make a right angle with each other.
