Description

Longitudinal slit casing tubes for light rails

The invention relates to a device for connecting a longitudinal slot Cladding tubes for busbars, fluorescent tubes or the like, with the facing each other Ends of the casing pipes connected by means of a connecting piece with approximately the same outer contour are, which are rotatably supported from each other about their respective central longitudinal axis There are sections whose end faces facing away from one another in a transverse to the longitudinal axis Lie level and their facing end faces with the other end face include an oblique angle with each other.

In technology, the connector consists of two equal parts that have a beveled face have so that the parts are aligned coaxially to one another in one orientation and include an angle of, for example, 135 ° in the position rotated by 180 °. Just in these two angular positions there is an arrangement of busbar casing tubes possible in one level. At other angular positions of the parts of the connecting piece is the arrangement in one plane is no longer possible, but the corresponding casing pipes run at a spatial angle to each other. The known connectors consist of tubular metallic molded parts, the end faces of which are each supported by a plate or the like are closed, each end face a passage opening for a large diameter Has flange screw, by means of which the connection of the abutting "valve pieces" is possible

this further section being designed symmetrically with respect to its center plane.

By arranging a third section between the previously common sections achieved in the appropriate training according to claim that different angular positions two casing pipes brought together at the connecting piece possible in one plane are. In addition, the variety of adjustments is significantly expanded by this training.

It is particularly preferred that the oblique angle be 22.5 ° with respect to the angle transverse to the central longitudinal axis running center plane.

Due to this design, the smallest angle between two converging on the connecting piece is 90 ° casing pipes. while the largest angle is 270 °. Any in between

Angular position can be aligned in this way. ; that the casing pipes to be connected in

run on one level. Of course it is

also possible spatial angles with the connector to manufacture.

A preferred development is seen in the fact that the middle section is on the front on both sides has a collar, the other parts made of half-shells of the same shape with the collar can be grasped from behind Flanged edges are formed and these half-cups are held together by fasteners extending transversely to the parting plane. In this way, the production is considerably simplified, since the entire device in principle consists of only two parts. One part is the middle connector, which can and should be designed in one piece. Pas

For further simplification, it is proposed that the Half-shells have pockets which are formed on the inside and are open towards the parting plane, in the holding projections engage a diametrically through the formed full shell extending holder, which Bracket has in the middle an adjustable and lockable pivot bearing for casing pipe holding means.

The assembly is facilitated by the fact that the casing pipe holding means are formed by a U-shaped bracket, the legs of the stirm surface of the section protrude axially outward and clamping parts spreadable from the legs wear.

Finally, it is also advantageous if the pivot bearing is between the sections and the center piece can be blocked by means of a screw passing through the section near the connection point is.

The invention is explained in the drawing using an exemplary embodiment. It shows:

4. The mutually facing ends of two cladding tubes 1 running at an angle to each other are by means of the connector consisting of parts 2 to 4, which has approximately the same outer contour as the casing pipes 1, join together. The connectors 2,3 are um their central longitudinal axis is rotatably supported on the connecting piece 4. Their faces facing away from each other run in a plane running transversely to the longitudinal axis, while the end faces facing each other Include an angle of 22.5 ° with the transverse plane. Close the end faces of the connecting piece 4 an angle of 45 ° with each other. This arrangement ensures that any angular position is adjustable between 90 ° and 270 °, although the connected casing pipes in can lie on one level.

In order to achieve the corresponding angular position, both sections must be relative to 2.3 Connector 4 rotated by equal amounts and in the same direction, thereby achieved is that the arrangement can be done in one plane. If spatial angular designs are required are, in each case the section 2 in the other direction or leading or lagging to Part 3 be adjusted.

In order to enable the rotary movement and to hold the parts together, the middle one has Part on the front side on both sides of the collar 5, while the other parts 2, 3 are each made of z ** ei Half-shells of the same shape are formed with flange edges 6 engaging behind the collar 5. The HaIb »Shells are particularly clear from FIG. 2. The half-shells are through a cross to the Fastening means extending along the dividing plane, for example a screw 7, are held together. at

If the half-shells are of identical design, only one half-shell is used during manufacture provided with threaded part 8 and the other with a continuous stepped hole 9 so that in the Bore 9 a head screw can be used, which is screwed into the threaded hole 8. That The initial pressed part is identical for both half-shells.

The half-shells of parts 2 and 3 have pockets 10 which are integrally formed on the inside and are open towards the parting plane on. In these pockets there are holding projections 11 diametrically through the full shell formed extending bracket 12 used, namely when pushing together the two half-shells. Through this the bracket 12 is securely set. The holder 12 has an adjustable and lockable one in the middle Pivot bearing 13 for casing pipe holding means 14.
