Problems solved by technology

The disadvantage of these common extension connections is that they also do not guarantee the reliability and stability of the connection, and most importantly they do not prevent the "shear effect" of the pipes twisting against each other

Embodiment Construction

[0013] The present invention relates to a pipe joint 10 for a simple, quick and secure connection of pipes 20, 20', rods or generally elongate hollow members. Briefly, pipes, rods or generally elongated hollow members will be referred to below as pipes 20, 20'. The present invention is particularly suitable for connecting two hollow tent support tubes of larger tents, wherein multiple tubes 20, 20' are connected with several pipe joints to create a free standing structure 30 (see, for example, Figure 40). According to the invention, it concerns an integral piece (preferably a plastic or metal piece) that can be used as the pipe joint 10 .

[0014] The object of the present invention is a tubular structure 30 with at least two tubes 20, 20' and an elongated three-dimensional cylindrical member into which the coupling 10 can be inserted. The pipe joint 10 connects the two pipes 20, 20', that is, the pipe joint 10 is inserted between the two pipes 20, 20' and inserted into the i...

Abstract

Tubular structure having at least two pipes (20, 20') and a plug-in pipe connection (10) which comprises a flange (1), wherein said flange (1) serves as an axial stop surface for terminal ends (21, 21') of the two pipes (20, 20'). Each side of the flange (1) is equipped with at least one lug (3) in order to engage in a corresponding cutout (22) in the terminal end (21, 21') of the respective pipe (20, 20'), wherein the lugs (3) engaging in the cutouts (22) prevent the pipes (20, 20') from twisting relative to one another. On each side of the flange (1) is provided a cylinder portion (5, 5') which can be plugged into the inside of the respective pipe (20, 20'). In addition, each cylinder portion (5) has an axial gap (7), resulting in flexible end pieces (9A, 9B) above and below the gap. The first flexible end piece (9A) has a radial bore (11) with a screw element (13) for tightly clamping the pipe connection (10) in the pipe (20, 20').

Description

technical field [0001] The present invention relates to pipe joints for connecting different pipes to form a self-supporting tubular structure, such as a tent-like structure, a pedestal building. Background technique [0002] In the field of tent-like structures and tubular structures in stilted buildings, there are various methods of connecting the tubes of these structures. The simplest of these methods involves inserting one end of a smaller bore tube into another larger bore tube. However, this method has various limitations due to the shape of the end of the pipe, and cannot ensure a firm connection and easy assembly at the same time. Furthermore, if the tube is flexible, such a connection is also unreliable since the tube tends to become loose. [0003] Other known pipe connections are inserted between two pipes and frictionally engage the two pipes. The disadvantage of these common extension connections is that they also do not guarantee reliability and stability o...
