Abstract

The invention relates to a pipe connector with a base body designed as a ball, which is designed such that six bores (16) offset by 90 ° for receiving the pipes to be clamped branch off, which meet in the center of the ball to form a double cross and are each longer than the sum of the clamping cylinder length and the center hole length (16).

Description

By means of this pipe connector, pipes can be screwed together with a certain diameter can be assembled into scaffolds such. B. in shopfitting, shelf construction, when setting up exhibition stands, when setting up of guardrails in mechanical engineering, etc., which are often dismantled have to. Such pipe connectors are said to be very compact on the one hand be det, but on the other hand the necessary for a safe pipe connection have stability. The pipes to be attached must be slightly mon be animal and disassembled, but with a secure hold Pipes in the pipe connector must not be omitted.

Tube connectors for receiving and connecting are already commercially available Licher pipes known (DE-GM 76 01 290), which consists of a quadratwür panel with all-round penetration openings with internal thread and there to be screwed hollow bracing nuts, which ih on the one hand, take the pipes inside and hold them by pressing. A sleeve for assembling several pipes is also known (FR 11 89 024), in which the pipes are provided on the pipe connector NEN hollow pin pushed on and by spreading the hollow pin with by means of clamping bolts and clamping wedges. This well-known pipe connectors require threaded connections to clamp the pipes with the pipe connector. Another pipe connector (DE 36 00 542) be stands out of a cuboid body, from which two, three, four, branch off five or six sockets with the pipe mounting holes;  in turn, actuating cylinders with two are rotatable on the receptacles coaxially offset bores are provided, which are twisted by a ver connect the pipe with the pipe connector. This system he calls for production to cover all connection options of up to eight different pipe connectors and therefore causes ne ben a very large expense in tool and manufacturing costs also a considerable storage capacity. In addition, twisting the Given tube when tightening an actuating cylinder and thus also twisting a pipe already mounted on the same pipe connector.

The invention relates to a device according to the preamble of Claim 1. Two different clamping variants are claimed. Variant 1 refers to a solution with a clamp that the ver Clamp pipe / pipe connector. In variant 2, two concentrically arranged cylinders rotated against each other so that a Clamping effect is achieved.

The object of the invention is to provide a pipe connector gangs mentioned to create the type that is easy to manufacture and compact construction a safe but nevertheless easily detachable connection easily without screws between pipes and pipe connectors Way to manufacture safely allowed, assembly and disassembly should be easy to perform even by inexperienced people as well as with a tube connector to cover all eight connection options are.  

To solve this problem, the characteristics of the characteristic part of claim 1 provided. Advantageous further training ent takes claims 2 to 25.

According to the invention are thus preferably formed as a ball Basic body initially six holes offset by 90 ° in all directions introduced in which the fixed mechanical clamping device tion elements and the holes for receiving the ver binding pipes, the holes for receiving the clamping cylinder or Sealing plug, the clamping cylinder against axial pipes pull out of the basic body until the clamp is secured Twisting the clamping cylinder is canceled. In addition, the Holes for receiving a sealing plug used when not Allocation of a bore with a pipe. When the clamp is released the pipes can be easily inserted through the clamping cylinder Base insertable while twisting after insertion of the clamping cylinder as well as the radial clamping of the pipes on the pipe connector can be achieved. Furthermore, the construction of the Boh stakes in the base body ball in connection with the clamp cylinder or plug so designed that both parts in the in clamped state cannot fall out and therefore cannot be lost are, however, easily pulled out or replaced when wanted can be replaced. Clamping cylinder and plug ha ben at least two or more holes on their actuating sides to hold a so-called face wrench for tightening (only to the right) or loosen the clamping cylinder (only to the left) and to change the two components. The operating pages of the Clamping cylinder or the sealing plug can be used as a flat surface  che as well as the spherical shape of the pipe connector can be adapted concave. Due to the training of the invention, the clamping cylinder must Achievement of a perfect clamping of the pipe in the pipe connector be rotated by at least 90 ° to achieve the required clamping to provide. The length of a path section, which is more, is preferred half a turn of the clamping cylinder is equal to 180 °, which leads to one is the one required to achieve a certain clamping force the required torque is reduced to the lowest possible value as well as an independent solution of the clamp connection optimally ver avoids. To twist the tube when tightening or loosening the Avoiding clamping cylinders in a pipe connector is in the clamp cylinders a plastic tube both rotatable and slidable on the mounting pipe, but only rotatable in the clamping cylinder bar built in, the wall thickness, strength and flexibility of the Plastic tube was chosen so that a safe and reliable Clamping between pipe and pipe connector is always guaranteed and there is no permanent deformation of the plastic pipe. With These systems use the greatest possible surface pressure between Clamping cylinder reached with the pipe to be clamped.

A practical and economical implementation of the invention is there characterized in that when one or more of the six connection options by exchanging the Klemmzy linders can be closed with a stopper and so with a change of the complete when changing the system geometry th pipe connector or change of the entire system unnecessary chen.  

Another object of the invention is to provide a pipe connector to write the written type in such a way that it is already extensive assembled system the easy replacement of a single pipe without influencing other pipe connections.

To achieve this object, the invention further provides that all six holes with at least the same diameter as the ver binding pipes in the center of the pipe connector ball into a double cross meet, preferably the bar length of this double cross is longer than the sum of a clamping cylinder and a pipe guide hole in the ball.

Thus, a pipe that is guided past a pipe connector can be closed next into the pipe connector provided at the other end so far be pushed that the pipe to the end of the parallel Bal cross hole comes to lie within the ball. Here is the other end of the pipe in front of the clamping cylinder of the other pipe connection placed so that now this end by moving the tube in the opposite direction in the clamping cylinder of the assigned Inserted pipe connector and thus the pipe firmly on both sides can be clamped. Conversely, moving one can be solved most pipe within the pipe connector also a specific pipe a complex assembled system can be removed without the other pipe connections must be loosened or otherwise changed sen. The only condition for a casual import and export of raw ren in a pre-assembled system is that the pipes are so long and elastic are that they take advantage of their elasticity and the drilling and Pipe tolerances can be offset laterally to such an extent that after  Slide out of the clamping cylinder next to the pipe connector to lie can come.

A preferred development of the invention is characterized in that that the diameter of the insertion bore of the clamping cylinder, which in the inner diameter of the plastic sleeve as well as the holes in the center of the clamping ball Double crosses are all the same and aligned in the respective levels and thus a complete push-through per connector in one case and Allowing a pipe to be clamped without the advantages of the other ver to influence binding possibilities in this pipe connector.

According to the invention, the ball diameter of the base body is so dim siones that both six clamps with six tubes each can be accommodated offset by 90 ° to each other, but the Fe rigidity and rigidity of the pipe connector is guaranteed.

The invention will be described below, for example with reference to the drawing wrote; in this shows:

The required clamping force is achieved in variant 1 according to FIGS. 1 to 9 by the arrangement of two surfaces running in a circle against one another by 90 ° to a maximum of 180 °, which in the developed state form inclined planes, one of which is in the respective bores of the Ball firmly, the other is spring-mounted on the guide cylinder of the clamping cylinder or sealing plug, each with an incline of approximately one degree and thus self-locking. The practical implementation of this embodiment is characterized in that the clamping offset is between 0.4 and 0.6 mm.

A practical dimensioning of this version is fiction, ge moderately chosen so that the contact surface of the clamping cylinder in the ball bore is approximately the same size as the contact surface of the resilient clamp device of the clamping cylinder.

Of FIG. 2 includes a spherical body, the z. B. can be made of aluminum, at six in all directions by 90 ° offset holes, which are designed so that they both the clamping cylinder of Fig. 5 to Fig. 8 with the tube 24 to be clamped and the United circuit plug can record of FIG. 9. The ball diameter of the version shown is approximately 8 cm, the surface distance between two opposing clamping cylinders is approximately 7.4 cm.

According to the invention, the bores according to FIG. 2 have the following functional details:
( 16 ) the inner centering for the pipe to be received, which is continuous in all levels, so that pipes to be assembled can be pushed through the center of the connector ball, which is essential for the assembly of a complex system, because here pipes can be used or be expanded, oh ne that the other pipe connections immediately following are impaired,
( 14 to 15 ) the centering hole for receiving and radially guiding the clamping cylinder or the sealing plug,
( 12 ) in Fig. 2 and ( 26 ) in Fig. 3, the guide groove, circumferentially between 180 ° and a maximum of 270 ° for receiving the resilient clamping tab Fig. 8 ( 43 ) or Fig. 5 ( 34 ), Fig. 6 ( 36 ), Fig. 4 ( 30 ), and thus for axial guidance and securing the Klemmzy cylinder or sealing plug. Continuously with the guide groove, the semicircular inclined plane begins in FIG. 3 ( 27 ) and ends continuously in the radius, becoming smaller by 0.4 to 0.6 mm in FIG. 3 ( 28 ), shown here only rotating 90 °, but preferably extending up to 180 °, on the one hand to achieve a greater clamping force, and on the other hand to achieve a secure jamming of an inserted tube with less use of torque on the clamping cylinder,

( 47 ) the center hole for a pipe to be received in a top view,

Fig. 4 of the clamping cylinder in the section AB with the outer Füh approximately cylindrical (32), the semi-circular, here shown with 90 ° resilient clamping bracket with the inclined plane starting at (29), ascending mm in radius around 0.4 to 0.6, ending at ( 30 ). The clamping cylinder is radially slotted in the area of the clamping tab at least 90 ° twice at a distance of 8 mm, starting at ( 29 ) and ending at ( 30 ), in the view it can be seen in Fig. 5 ( 33 ) and ( 35 ) and axially slit Fig. 7 ( 37 ) after the highest point of the clamping tab Fig. 4 ( 30 ), beginning and ending at the ends of the radial slots ( 33 ) and ( 35 ). This construction allows the spring clip to spring freely in the direction of the central axis of the clamping cylinder with pivot point ( 29 ) in FIG. 4, provided that the clamping cylinder is rotated clockwise in the direction of the inclined plane between FIGS . 3 ( 27 ) and ( 28 ) and from this inclined plane Pressure is exerted on the inclined plane of the clamping tab. In the unclamped state, the clamping lug of the clamping cylinder runs with slight axial play in the groove ( 12 ) Fig. 2 of the clamping ball and thus prevents loss of the clamping cylinder in the unclamped state. In addition, this con construction allows a problem-free replacement of the clamping cylinder against a sealing plug in that the pulling out of a clamping cylinder or sealing plug by turning these components clockwise until the highest point of the clamping tab of the clamping cylinder, Fig. 4 ( 30 ) or sealing plug with the highest point of the inclined plane of the clamping ball Fig. 3 ( 28 ) opposite, is possible; conversely, the insertion of a Klemmzy cylinder or sealing plug is made possible by attaching the guide cylinder of one of the aforementioned components Fig. 8 ( 42 ) or Fig. 9 ( 47 ) into the centering hole Fig. 2 ( 15 ), then push further into this hole until Stop of the clamping tab ( 43 ) Fig. 8 against the bevel Fig. 2 ( 17 ), which easily overcomes the resistance of the clamping tab spring and presses inwards, then push it further until the stop or until the clamping tab Fig. 8 ( 43 ) into the groove Fig. 2 ( 12 ) of the clamping ball engages.

A plastic tube Fig. 8 ( 40 ) and in section AB in Fig. 4 ( 31 ) is rotatably fitted in the clamping cylinder Fig. 8, captive in the installed state, with an inner diameter equal to that of the inner diameter Fig. 8 ( 48 ) of the clamping cylinder or the centering diameter Fig. 2 ( 16 ) of the clamping ball, with all these inner diameters being dimensioned such that a pinching of the tube can be inserted easily rotating with a slight play. The plastic tube has a wall thickness of z. B. 1 mm and largely prevents rotation of the pipe to be clamped when turning the clamping cylinder or jamming a pipe with the pipe connector. In order to achieve a clamping tube / pipe connector, a clamping cylinder Fig. 2 (21) is mounted with a plastic socket Fig. 2 (22) in a bore of the pipe joint ball rotatably, that only by the clockwise rotation of the jaw cylinder Fig. 2 (21), the Running against each other on the inclined plane Fig. 4 ( 29 ) to ( 30 ) against the inclined plane Fig. 3 ( 27 ) to ( 28 ) brings about the radial pushing in of the clamping tab Fig. 2 ( 21 ) and thus via the plastic sleeve Fig. 2 ( 22 ) Clamping the tube Fig. 2 ( 24 ) allows. Turning the clamping cylinder to the left within the clamping connector is only possible until it is blocked with the clamping tab Fig. 4 ( 30 ) by Fig. 3 ( 28 ), but does not cause any clamping.

In contrast to variant 1 described above, in the case of variant 2 according to FIGS . 1 and 10 to 17, the radial clamping of an inserted tube ( 40 ) is carried out by a radial clamping cylinder ( 45 ) which is in the cylinder bore ( 13 ) of the spherical base body ( Fig. 10) is rotatably mounted.

The central axis of the bore Fig. 10 ( 12 ) is eccentrically offset, for example, 0.5 mm (X) to the central axis of the bore Fig. 10 ( 13 ), as is the central axis of the bore of the clamping cylinder Fig. 15 ( 16 ) and the central axis of the receiving bore Fig. 15 (23) of the plastic cylinder Fig. 15 (22) opposite the central axis of the circular cylindrical outer diameter of Figs. 15 (18) of the clamping cylinder.

When the clamping cylinder pin Fig. 15 ( 20 ) or Fig. 13 ( 35 ) turns to the left in the groove Fig. 11 ( 25 ) to ( 26 ), the hole Fig. 15 ( 17 ) is aligned with the hole Fig. 10 ( 12 ), so that a tube can be inserted up to the transverse bore Fig. 10 ( 21 ), as shown in Fig. 10 ( 40 ). The clamping cylinders FIG. 15 by the guide pin Fig. 15 (20), which in the guide groove Fig. 10 (15) or FIG. 11 (25) is led to (26) a maximum of 180 ° rotation.

The clamping ball bore diameter Fig. 10 ( 12 ) and the plastic cylinder diameter Fig. 15 ( 17 ) are cylindrical and correspond to that of the tube diameter so that pipes to be clamped fit into these holes with little play. The bore of the clamping cylinder Fig. 15 ( 16 ) is a few tenths of a millimeter larger than the plastic cylinder bore Fig. 15 ( 17 ), so that only the plastic cylinder comes into play during the clamping process.

The plastic cylinder Fig. 15 ( 22 ) is rotatably mounted in the clamping cylinder bore Fig. 15 ( 23 ), but in the inserted state of the clamping cylinder in the clamping ball axially not displaceable and cannot be lost and prevents when turning the clamping cylinder or when clamping a pipe in the pipe connector turns the pipe to be clamped. The material of the plastic cylinder is selected so that permanent deformation cannot occur. The plastic cylinder has a wall thickness of z. B. 1 mm.

So that the clamping cylinder Fig. 10 ( 45 ) or sealing plug Fig. 10 ( 24 ) in the spherical body Fig. 10 cannot come out unintentionally, a pressure piece Fig. 15 ( 19 ) is provided in the clamping cylinders or sealing plug, the resilient ball in the Groove Fig. 10 ( 14 ) is performed and allows only a deliberate removal of these components.
