Description

20 25 ïEÉBÉ EEE 2 styvheten. Överdelen 2 är böjd i en vinkel i storleksordningen 90° till l00°. Den av ett sammanhängande stycke bestående rörhållaren 1 är förstärkt med ett forstyvningselement 4, som samverkar med över- och underdelarna 2, 3 och vid det i figuren visade utforingsex- emplet likaså består av massivt PP-material, dvs. ett material utan till exempel forstyv- ningribbor. 20 25 ïEÉBÉ EEE 2 stiffness. The upper part 2 is bent at an angle of the order of 90 ° to 100 °. The tube holder 1 consisting of a continuous piece is reinforced with a stiffening element 4, which cooperates with the upper and lower parts 2, 3 and in the embodiment shown in the figure also consists of solid PP material, ie. a material without, for example, stiffening ribs.

Förstyvningselementet 4 har företrädesvis till uppgift att ta upp belastningen på över- och underdelarna 2, 3 från det mot en återställningskraft böj da och i ﬁg 1 icke visade plaströret. Plaströret kan for övrigt även vara sammansatt av flera skikt.The task of the stiffening element 4 is preferably to take up the load on the upper and lower parts 2, 3 from the plastic pipe not bent towards a restoring force and not shown in Fig. 1. The plastic pipe can also be composed of several layers.

Den på underdelen 3 anordnade svängbara ﬁxeringsanordningen 5 omger i insvängt läge ungefär halva Omkretsen for röret och har i den fria änden minst en spärr- eller lås- anordning 6, som samverkar med rörhållarens underdel 3 på sådant sätt att plaströret hålls fast.The pivotable mounting device 5 arranged on the lower part 3 surrounds in a pivoted position approximately half the circumference of the pipe and has at the free end at least one locking or locking device 6, which cooperates with the lower part 3 of the pipe holder in such a way that the plastic pipe is held.

Fixeringsanordningens 5 spärr- eller låsanordningar 6 är enligt en foredragen utfo- ringsfonn utförda med spärrhakar eller spärrklackar 6a, 6b, som till exempel fors in i motstående öppningar 7a, 7b på utsidan A av rörhållarens 1 underdel 3.According to a preferred embodiment, the locking or locking devices 6 of the fixing device 5 are made with locking hooks or locking lugs 6a, 6b, which are for instance inserted into opposite openings 7a, 7b on the outside A of the lower part 3 of the pipe holder 1.

Fixeringsanordningen 5 är företrädesvis svängbart förbunden med rörhållarens l underdel 3 med hjälp av en gånärnsstruktur 8.The fixing device 5 is preferably pivotally connected to the lower part 3 of the pipe holder 1 by means of a hinge structure 8.

När det i förväg böj da plaströret har förts in och ﬁxerats i underdelen 3 med hjälp av fixeringsanordningen 5 kan det foras eller skjutas in i rörhållarens 1 överdel 2 i det i förväg böjda tillståndet, så att det därefter hålls fast i det vinkelböjda tillståndet i den ringforrniga/cylindriska innerdelen 10 av överdelen 2. Innerdelen 10 har därvid något större innerdiam eter d än plaströrets ytterdiameter.When the plastic pipe has been pre-bent and inserted into the lower part 3 by means of the fixing device 5, it can be lined or pushed into the upper part 2 of the pipe holder 1 in the pre-bent state, so that it is then held in the angularly bent state in the annular / cylindrical inner part 10 of the upper part 2. The inner part 10 then has a slightly larger inner diameter ether than the outer diameter of the plastic pipe.

Rörhållarens l överdel 2 har på utsidan A' minst två motstående anordnade låsele- ment 9a, 9b, med vilka rörhållaren kan fästas lägesstabilt i en på ritningen icke visad öpp- ning i en väggmonteringsplatta. När röret har fästs och ﬁxerats i sitt vinkelböjda tillstånd och rörhållarens 1 överdel 2 har låsts fast i en monteringsplatta genomförs ett tryckprov for kontroll av den monterade enhetens täthet.The upper part 2 of the pipe holder 1 has at least two oppositely arranged locking elements 9a, 9b on the outside A ', with which the pipe holder can be fixed in a position-stable manner in an opening in a wall mounting plate not shown in the drawing. When the pipe has been fastened and axed in its angled condition and the upper part 2 of the pipe holder 1 has been locked in a mounting plate, a pressure test is performed to check the tightness of the mounted unit.

Claims

10 15 20 25 30 35 40 5 3 'ä 9 8 3 3 Patent claims

Pipe holder (1) for holding and fixing bent plastic pipes in a mounting plate, preferably a wall mounting plate, characterized by the following combination of features: - a) the pipe holder (1) is formed in one piece by an upper part (2) and a lower part (3), the upper part (2) being arranged for fixing in the mounting plate and for inserting the end of the pipe and the lower part (3) is half-cup-shaped for loading the pipe, - b) the upper part (2) is bent at an angle towards the mounting plate , the angle preferably being in a range from 90 to 120 degrees, - c) the lower part (3) has a pivotable fixing device (5), which surrounds about half the circumference of the tube and on its one side is pivotally connected to the lower part (3) and on its other side has a free end, - d) the fixing device (5) has at its free end at least one locking or locking device (6), which in the pivoted-in position of the fixing device cooperates locking with the lower part (3) and thereby ﬁ axes the tube between fixers the fixing device (5) and the lower part (3), - e) the fixing device (5) is pivotally connected to the lower part (3) of the pipe holder (1) by means of a hinge structure (8).

Pipe holder according to Claim 1, characterized in that the pipe holder consisting in one piece of the upper part (2), the lower part (3) and the fixing device (5) is made of polypropylene.
