Pipe coupling

Technical field

The invention of circular and spatial relates to a pipe connector intended to connect other pipes in three basic directions of a rectangular system.

BACKGROUND OF THE INVENTION

The known coupling for joining the pipes of which the modular furniture is assembled is designed as a simple plastic connecting piece with tubular end pieces on which the ends of the connected pipes made of paper are pressed. These couplings are manufactured in many designs as two to six times depending on the number of pipes to be connected to each other.

SUMMARY OF THE INVENTION

The above-mentioned disadvantages are overcome by the pipe coupling according to the invention, which consists of a spherical element as a central connecting element, which is provided on both opposite sides of all three basic mutually perpendicular directions with six cylindrical projections, centered with continuous square holes connecting opposing cylindrical protrusions, and a flange-shaped end having a cylindrical recess corresponding to cylindrical protrusions, wherein the spherical element and the end are connected to each other by a quadrilateral prism provided with flexible protrusions at their ends on the other hand, into the square hole at the end of the flange of the terminal when connected together.

The advantage of the pipe coupling according to the invention is that it can be used universally even for a plurality of pipes to be joined, since it ensures the connection of the pipes in all directions, and the formation of a secure and firm connection of the pipes to be joined.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a pipe connector assembly of a spherical element, a square prism end and a pipe end to be joined; and FIG. of a spherical element, a rectangular connecting prism and a terminal.

DETAILED DESCRIPTION OF THE INVENTION

The pipe coupling consists of a spherical element 1, as the main part, which is a central connecting element to which one to six pipe ends 2 can be mechanically connected. The spherical element 1 is on both opposite sides of all three basic mutually perpendicular directions provided, for example, with six cylindrical protrusions 5, in the center of which are continuous square holes 6 connecting the opposing cylindrical protrusions 5. To the circular faces 2 of cylindrical

Even the protrusions 5 can be attached with Velcro.

The end piece 2 has the shape of a cylinder with a flange 8 and is inserted into the end of the pipe 4 to be connected. From the outer face on the side with the flange 8 the end piece 2 has a cylindrical recess 9 corresponding to the cylindrical projections 5 on the spherical element 1 and a square bore. a rectangular prism 3 corresponding to the square openings 6 in the spherical element 1 extends from the square opening 12 of the terminal 2 in the axis 2, corresponding to the square holes 6 in the spherical element 1. The transverse notch 10 and resilient protrusions 11 at the end A velcro can be affixed to the end face 2.

The Velcro fasteners provided on the circular ends 7 and the end face 2 serve to strengthen the joint. The hook-and-loop fastener provided on the circular face 7, which remains free, serves to attach various aids.
