Two-part Selielle for the articulated connection of pipes

The innovation "refers to a two-part clamp for articulated Connection of pipes.

For rigid connection of pipes, e.g. in scaffolding, clamps are used known, in which the associated files provided with half shells are connected to one another via visual shafts. The half-shells encompass the pipes, while the connecting screws provide sufficient frictional connection between the Guarantee half-shells and the pipes. "

In addition to these rigid pipe connections, there are those in which the pipes must be hinged to one another.

It is known, for example, for clip-on frames for wooden pallets, two to articulately connect side frames assigned to one another, so that the frames collapsed during use can be. For this purpose, hinges are provided in the area of the vertical boundary tubes of the single frame, which are known in a variety of constructions «

.- 2

The innovation is initially based on the task of developing a hinge that is simple and light in construction can be mounted «

Ba the lame pipes a surface protection, ζ · Β · a lacquer or If they have a plastic layer, the hinge parts must not interfere with the surface coating of the ears.

Another task of the innovation is the creation of a hinge that, after the surface finishing of the Eohre can be mounted

A two-part hinge clamp is used to solve these tasks proposed after the innovation, in which the eye parts are formed the same, on one side your Einsteoknut and on the other side have a corresponding plug-in strip, and rotated by 180 ° against each other in a form-fitting manner are connectable

Because the same clamp halves are used, the ! production and storage particularly easy

The form-fitting connection is on one side of the Clamp part is provided with an insertion groove that is flanged of an end lobe results. This groove becomes the plug-in strip of the associated clamp part rotated by 100 ° inserted · The final connection of the clamp parts is made in the middle section by means of a plug, rivet or screw connection.

The half-shells of the clamp parts are dimensioned so that after the final assembly of the clamp between the

Half-shells enclosed tubes and the half-shells a minor one Hardly remains so that an articulated connection between the sound of a clamp is given

live a joint connection in which a relative movement is possible between the two pipes and the clamp, an articulated connection can also be of interest, in which a pipe is torsion-proof attached to the clamp.

According to the innovation, the clamp on a Pipe splinted or non-rotatably on one with a pin Pipe attached.

The same purpose can be achieved by having four opposite half-shells two opposite half-shells do not have an arcuate contour, smaller in radius and tightly enclose one pipe.

Further features of the fire can be found in the subclaims and the following description of an advantageous, exemplary embodiment

Show it:

1 shows a wooden pallet with a collet frame in perspective Opinion,

FIG. 2 is a perspective view of a Sehelle, one of which «Half of the clamp shown in solid lines and the associated half of the clamp in dash-dotted lines Lines is indicated,

3 shows a half of the clamp in plan,

Pig. 4 two half-shells placed one on top of the other for assembly, partially cut vertically.

The new hinge clip can be used for all kinds of articulated pipe connections. In Fig. 1 is an application example shown. The side frames 1 and 2 of the towing frame are articulated to one another via hinges 5 »4. To the frames 1, 2 collapsed by pivoting in the hinges 3j 4 will"

These hinges can have the three-dimensional shape shown in the 2 to 4 is shown.

A middle piece is located between the half-shells 7 and 8 9, which has a protruding nose 10, and a plug-in opening * - · tion 11 is equipped. In the exemplary embodiment, the nose 10 is punched out of the center piece 9.

There is an insertion groove on one side of the armpit half 12, which is formed by flanging a rectangular tab 13. This manufacturing process is shown in FIG. 2 indicated in dash-dotted lines. The dash-dotted lines show an intermediate position. The final molding takes place sighting arrow 14 "

On the other side of the armchair half is a push-in strip 15 arranged, at the upper and lower end of this plug-in strip beveled edges 16, 17. After inserting the

Insert strip 15 in the groove 12 of the associated clamp half k ^ nn at the top and bottom of the groove the material of the boundary walls are deformed and fix the inclined edges 16, 17 against vertical displacement

Bas center piece 9 can opposite the plug-in strip 15 and the Groove boundary wall 18 be offset to the outside »The offset is so strong that the nose 10 when the armor halves are folded together does not penetrate into the opposite insertion opening 11 * Only when there is sufficient pressure on the middle section 9, the noses 10 pass through the associated insertion openings 11 * The part of the noses protruding from these insertion openings is turned upwards or downwards so that a

A perfect connection between the halves of the armor is created. In

Modification of this construction is also possible to AiLkJc »on

to dispense with the displacement of the middle piece

In the pig. 4 the clamp halves are set to each other. One Deformation of the center pieces 9 has not yet taken place.

This representation also shows that the half-shells 8 and 8 have an arcuate contour, so that the distance between the half-shell and the ear 19 in the middle of the clamp is less than at the upper and lower edge of the clamp. Through this The measure is the surface layer of the pipe when the pipe is tilted largely spared.
