Abstract

Pipe joint comprising a pipe clamp (1) and a pipe counterpart (2) partially inserted into and surrounded by the clamp (1), characterized in that the counterpart (2) has at least one annular locking projection (3) which is arranged in the immediate vicinity of the pipe end on the lateral surface thereof, wherein the clamp (1) has at least one suitable securing hook (4) which engages over the upper edge of the locking projection (3) and the clamp (1) against the counterpart (2) holds that the clamp (1) and the counterpart (2) can rotate freely against each other in a connection situation, wherein the pipe connection is part of an air conditioner and wherein the pipe connection connects an air exhaust pipe with a diffuser.

Description

The The invention relates to a pipe joint, a pipe clamp and a pipe counterpart that partially inserted into the clamp of the pipe and can be surrounded by the clamp.

pipe Fittings There are known to be in various embodiments. For example sleeves in the area of the connection piece arranged around the pipe, their ends by means of a thread be tightened. On the other hand, parentheses are known whose scope is reduced by means of pliers. In general, the manufacturing costs for the Pipe joints, which represent a mass production product, very high, such as in the case of screw terminals, or the holding force is limited or proves to be unreliable.

The patent AT 385,336 represents a pipe joint, the connecting piece, which is located below a groove, projecting in the case of a fixing process from the inner diameter of the sleeve and presses the pipe against a fitting.

In In this case, the fact means that a mechanical force is exerted must be to the connector to push down against a resistance, a disadvantage. In the event of of screw caps Again, the fact means that as soon as the pipe piece bolted to the counterpart and the thread is tightened, the tube is not in the thread can turn more, a disadvantage.

Therefore the present invention has the object, a pipe joint provide that is easy to close and at the same time the turning ability ensured the tube.

These Task is according to the invention for one Pipe connection, among other things, solved by the fact that the pipe connection comprises a pipe clamp and a counterpart, partially inserted into the clamp and surrounded by this can be, wherein the pipe counterpart at least one annular locking projection in the immediate vicinity of the pipe end on the lateral surface the same is arranged. Furthermore the pipe clamp has at least one suitable safety hook up, over the upper edge of the locking projection attacks and the clamp so on the pipe counterpart fixed that the pipe clamp and the pipe counterpart themselves in a connection situation can rotate freely against each other.

The solution according to the invention leads to a pipe joint compared to the current state the technique is improved. Since the locking projection is annular is and in its entirety the attachment of the pipe counterpart parallel At the end of the pipe, the clamp and the counterpart are given the opportunity upright, to turn against each other even if the safety hook on the upper edge of the locking projection attacks and the clamp against the counterpart holds. The counterpart of the safety hook that over the upper edge of the locking projection attacks freely over the pushed the upper edge of the locking projection. If desired, to solve the pipe connection, can be the counterpart pulled out of the clamp by pulling. The safety hook, at least one, may be designed such that the counterpart easily can be pulled out, but it can also be carried out in such a way that's the counterpart is firmly fixed and only when exerting pressure against the bottom of the safety hook are solved can.

According to the invention Pipe connection of the invention designed as part of an air conditioner. this means a special advantage, since the air conditioners often a Modification of the position of a pipe is necessary. This embodiment guaranteed that the pipe joint then a hermetic seal maintains, when the pipe turns or changes position.

In a preferred embodiment is the pipe joint as part of an inner module of a mobile Air conditioning running.

Connects according to the invention the pipe joint of the invention, an air exhaust pipe with a diffuser an air conditioner. This proves to be particularly advantageous because the position of the air exhaust pipe usually in dependence modified by the conditions of the habitable space. In this case has to be ensured that the pipe connection is permanent despite the position change and the rotation and closes safely.

In a preferred embodiment the tube is made of plastic.

Further Features and advantages of the invention are as follows Description of an embodiment with reference to the accompanying drawings.

2 shows a view of a pipe joint according to the invention from above in diagonal position schematic diagram.

1 shows a side view of a closed pipe connection. This is the tube counterpart 2 in the appropriate clamp 1 introduced. Around the neck of the counterpart 2 becomes an annular locking projection parallel to the plane of the tube end 3 arranged. If the counterpart 2 in the clamp 1 is inserted, presses the annular locking projection 3 against the sides of a chamfered safety hook 4 , If subsequently the counterpart 2 continue towards the clamp 1 is moved, the safety catch engages 4 above the upper edge of the annular locking projection 3 at. In this way, the counterpart 2 and the clamp 1 firmly connected, so that the counterpart 2 not accidentally out of the clamp 1 can slide. Due to the annular design of the locking projection 3 becomes the safety hook 4 in any angular position through the locking projection 3 fixed. This will ensure that the clamp 1 and the counterpart 2 can rotate freely against each other.

2 shows the pipe connection according to 1 in a view from above in inclination. Specifically, a pipe joint is shown in which the diffuser of an air conditioner is connected to the pipe section of the air conditioner.
