Definitions
- the present invention relates to a connecting and deflecting element for tension belts in a pneumatic component according to the preamble of patent claim 1.
- the tensile loads which occur are transmitted from a node element to the pneumatic component by means of tension bands.
- At least two drawstrings are to be provided, which, starting from the two node elements of the pneumatic component, are placed around the pneumatic component in opposite screwing directions and tightened. If there are two drawstrings, they cross each other at one point; however, if there are four drawstrings, depending on the design of the loop angle and the number of nodes provided, at least three crossing points are already possible.
- the positions of the crossing points mentioned are easy to determine mathematically. However, technical compliance with the prediction depends not least on the craftsmanship that is used in the construction and set-up of such a pneumatic component.
- the crossing points are the cause of faults in the shape of the outer skin of the pneumatic component, in particular if the drawstrings are designed as steel cables.
- the object of the present invention is to provide a connecting and deflecting element of the type mentioned, which allows the disadvantages listed to be overcome and which, moreover, can be produced inexpensively as a series product.
- FIG. 2 shows a first exemplary embodiment of a connecting and deflecting element
- FIG. 3 shows the first exemplary embodiment of a connecting and deflecting element in an isometric illustration
- FIG. 5 shows a second exemplary embodiment of a connecting and deflecting element in an isometric illustration
- 10 is a first variant of the second embodiment in an isometric view
- 11 shows a variant of the first exemplary embodiment in an isometric illustration
- FIG. 13 shows a cross section of the second variant of the second exemplary embodiment.
- FIGS is an isometric view of a pneumatic component according to the prior art. It is constructed from an essentially cylindrical, gas-tight hollow body 1 with two caps 5. A compression rod 2 is clamped between two node elements 3. On this also two drawstrings 4 are attached, which are guided in the opposite direction of the screw around the hollow body 1 and bear tightly against this. The drawstrings 4 cross each other on a surface line ⁇ , which runs opposite the pressure rod 2, on half the length of the cylindrical hollow body 1 at a crossing point 7.
- FIGS A first exemplary embodiment of a connecting and deflecting element according to the invention is shown in FIGS ; FIG. 2 shows a top view, FIG. 3 shows an isometric view.
- a plate 8 which is bent as a basic shape so that it lies flat against a hollow body 1 with a certain diameter, has a cutout 9.
- Two drawstrings 4 in the form of cables 11 are inserted into the cutout 9 and lie there tangentially without kinking.
- Two dash-dotted lines 10 denote the lines of action of the cables 11.
- the lines of action 10 intersect at the intersection 7, and denote the course of the tensile forces passing through the cables 11.
- the cables 11 themselves no longer have an intersection.
- Four threads 13 are provided for a cover, not shown, which can be screwed onto the connecting and deflecting element as a variant.
- FIG. 4 In cross-section AA according to FIG. 4 there are four cables 11, two adjacent ones form a drawstring 4.
- a cover 14 is provided in order to guide the cables 11 side by side.
- the cover 14 can be designed in such a way that it clamps the cables 11 at the same time, or it is the carrier of a - known, but not shown - clamping device.
- the fully formed plate 8 - including the shaped element referred to as milling 9 - can be produced by stamping, drop forging, extrusion or the like, that is to say generally by a non-cutting molding process, which can reduce the unit costs considerably.
- FIG. 5 are illustrations of a second exemplary embodiment of the connecting and deflecting element; Fig. 5 in isometry, Fig. 6 as section BB.
- This is designed as a hollow body 15 with a bend suitable for the pneumatic component of the selected size.
- the clear height of the hollow body 15 provided transversely to the cables 11 is dimensioned such that it corresponds to the diameter of the cables 11 in such a way that they can be pulled in without clamping. Subsequent clamping of the cables 11 can be brought about by deforming the flat hollow body 15 or by wedging.
- a variant of the second exemplary embodiment according to FIG. 7, shown in section analogously to FIG. 6, is provided for receiving four or more cables 11.
- FIG. 8 A third exemplary embodiment of a connecting and deflecting element according to the invention is shown in FIG. 8.
- a connecting and deflecting element 24 constructed from two essentially identical parts 22, 23 is held together by a schematically illustrated screw connection 25. The entire axial projection of the tensile forces therefore runs through the screw connection, which is designed to be correspondingly tensile, for which means and materials are known per se.
- the cables 11 are fastened in anchors 26 with a spherical cap-shaped outer contour. These lie in pans 27 of a corresponding shape, so that no bending moments act on the fastening points of the cables 11. Versions 28 for the cables 11 are designed conically. This allows slight deviations from the nominal geometry of the pneumatic component to be absorbed.
- the connecting and deflecting element 24 can be designed analogously to that according to FIG. 4 as a curved plate, or analogously to that of FIG. 10 as part of the pressure rod 2. In the latter case, the screw connection 25 has only adjustment tasks or can also be omitted entirely.
- the connecting and deflecting element 24 can also be designed for more than four cables 11, regardless of whether the cables are then to be arranged in one or more levels.
- the connecting and deflecting element 24 is used in particular where numerous tension bands are provided for a pneumatic component, for example in the case of a pneumatic component used as a column and loaded axially.
- a pneumatic component used as a column and loaded axially.
- a pneumatic component has two or more pressure rods 2 and, as shown in FIG. 1, two tension bands 4 are assigned to each pressure rod 2, intersection points 7 result on or under the pressure rods.
- connecting and deflecting elements 8, 15, 24. 9a, b show schematically how a deflection element 8, 15, 24 is divided parallel to the pressure rod along its center line 31, so that two functional halves 18, 30 are created. These functional halves 18, 30 can now be joined together in different ways to form further variants of deflection elements which avoid crossing points 7 on a pressure rod 2.
- the functional halves 18, 30 are fastened to a base plate 32 in such a way that an intermediate space is created for the pressure rod 2.
- a cover 14 can also be attached, with which the pressure rod is enclosed by the deflecting element. It is also according to the invention to attach the two functional halves 18, 30 only to the cover 14 and not to use a base plate 32.
- a second variant (FIG. 9d) is based on inserting between the two functional halves 18, 30 a middle part 21 which can be subjected to pressure and which is attached between pieces 20 of the pressure rod 2 and thus becomes part of the pressure rod.
- the functional halves 18, 30 are provided with comb-like protuberances 17 and the pressure rod 2 with grooves 16 that match these protuberances 17.
- the functional halves 18, 30 can now be inserted and positioned in the grooves 16.
- the protuberance 17 on the pressure rod 2 and the groove 16 on the functional halves 18, 30 is also according to the invention.
- 10 to 12 show connecting and deflecting elements, which correspond to the three variants in FIG. 9, in an isometric representation.
- the connecting and deflecting element shown in FIG. 10 is placed over the pressure rod 2, so that one hollow body 18 rests laterally on the pressure rod 2.
- the hollow bodies 18 can be set up to accommodate one or more cables 11 each.
- the connecting and deflecting element in FIG. 11 is designed to receive one or more cables 11 on each side of the pressure rod 2. It is also designed so that it can be inserted between two pieces 20 of the pressure rod 2; .a.W., Its middle part 21 is itself part of the pressure rod.
- the alignment of the parts 20, 21 of the pressure rod 2 can be forced using known mechanical means.
- the compression rod 2 in FIG. 12 laterally carries a groove 16, which are used to receive protuberances 17, which are formed on flat hollow bodies 18.
- the hollow bodies 18 can be designed such that they are suitable for one or more cables 11.
- FIG. 13 is a sectional view DD of FIG. 12.
- the hollow body 18 with its protuberance 17 was formed by reshaping a pipe section and inserted into the groove 16 of the pressure rod 2.
