0005This object is achieved by the fact that the Connecting the elements by means of a plug-in element is carried and the positive engagement of the connection by foreign and corresponding Internal teeth is formed.

0006Advantageous developments of the invention are in the Dependent claims.

0007The clamping device according to the invention comprises a male member on which to connect all components of the device to one another is used. This plug-in element connects the individual elements to one another positively and releasably. It is preferably provided with external teeth, which is a can be multi-tooth profile or a notched profile or the like. The elements to be connected have in each case at the joints continuous recesses, which with an inner toothing provided that the profile of the external teeth of the male element corresponds.

0008The tooth profile of the male element and of the connecting elements the apparatus preferably includes an angular pitch of 15 °. This is on manufacturing processes, through a corresponding production methods may of course smaller or larger angular pitches can be realized. The plug is preferably rod material in simple advantageous manner for the corresponding Connections can be diverted. It is also conceivable that the Male member to manufacture than a sintered part. The plug and the connecting members of the device consist of a Metal is preferably an aluminum alloy.

0009The introduction of an internal toothing in the connecting elements the device is advantageous simply because it around Through holes are. Thus, the design is the Fasteners advantageously not restricted.

0010The multi-tooth profile or notched profile of the compounds ensuring a positive connection. The Fasteners are with the plug-in elements on different locking elements fixed. The locking elements are preferred embodiments known example as Grub screws. It is also known clamping elements of the End side of the male element to be mounted, which the Plug-in element and the connecting member respectively to each other fasten. It is also conceivable that the plug element and the a connection element via a pin connection are fixed to each other.

0011In another embodiment of the invention, it is provided with a Noniuselement advantageously possible smaller angular steps to receive. This Noniuselement has, for example in a Design an interior through opening with a to Male member corresponding to internal teeth, which is simultaneously has an external toothing, which for a Internal gear different angular pitch having. These External teeth of the Noniuselementes is then reacted with a corresponding internal teeth of a connecting element mated with different by the given angular pitches additional settings.

0012The assembly of the device according to the invention advantageously simple. This requires that the provided fasteners each with a plug-in element be and each other in the corresponding angle are plugged together. Thereafter, they are by means of suitable Arresting fixed. In a further embodiment , the plug-in elements a guide pin on which a Outer diameter which is slightly smaller than the Inner diameter of the corresponding internal toothing. Thus, it is simplest possible that upon release of the compounds of Fasteners or before the positive mating the fasteners they are already plugged into one another may, where they advantageously easily aligned with each other be and mated form fit after alignment will.

0013It is also possible, in addition to the guide pin and in place of the guide pin, the internal toothing of the respective to provide the connecting element with a recess, which these qualities of leadership allows. It is this Recess provided with a diameter that is slightly larger than the outer diameter of the outer teeth of the male element. The terms used in outer diameter and Inside diameter for external toothing and internal toothing equivalent to those tip diameter for ID or External teeth.

0014With the device according to the invention, it is further advantageously possible more than two connecting elements by means an interconnection sew together. On Plug member can be made in its length so that it on both sides of a through hole of a connecting element protrudes, with more on the projecting ends applied fasteners at desired angle intervals can be.

0015Thus, a tensioning device for elements is to be mounted created on devices which front in advantageously adapted to mating, mated positively and can be fixed. This is advantageous with a low Number of connecting elements possible. It is of course conceivable that the profiling of the plug-in elements and the associated through holes of the connecting members also be made of other profiles than those described can. The profiling of the plug elements and the through holes of the connecting elements takes place in the longitudinal direction of the The male element or of the passage opening in a Connecting element.

0021In Figure 1 it is shown that the joint to the carrier 8 The base element 2, a supporting head 12 to be pivoted about a Longitudinal axis of the knuckle 8 standing transverse axis and means Locking screws 11 mounted fixable. The support head 12 has in its upper region a continuous recess, in which a male member 14 is introduced, which is based on one side is extended. The plug 14 and the have corresponding through hole of the supporting head 12 a profile on which a positive connection between the Supporting head 12 and the plug member 14 is prepared. On the protruding end of the male element 14 is a connection element 13 applied. This connecting element is in this Embodiment of straight elongated shape and comprises on both Ends a profiled through hole on whose Profile correspondingly also formed of the male element 14 is.

0022At the upper end of the connecting element 13 is a further Connecting element 13 'by means of the male element already described 14 attached. At the upper end of this connecting element 13 is also an introduced Plug-in element 14, on which a mounting member 16 with is postponed fixing holes 17th

0023The connections between the head support and the connecting element 13 as well as between the latter and the connecting element 13 ' as well as between the latter and the mounting member 17 each form an axis 21, about which the elements that these respective Connection form to solution of the respective profiled be male member 14 is pivoted and put together again can.

0024The plug 14 and the corresponding receiving openings in the individual connecting members 13, 13 'as well as in Mounting member 16 and the support head 12 as well as in other no fasteners shown are each about the Axis 21 form-fitting releasably in angular steps each connected. In a preferred embodiment, the plug-in element 14 multi-tooth profile on an external gear, which parallel to the longitudinal axis of the male element 14 Gradient is trained. This multi-tooth profile can also be a standardized its notched profile. The respective receiving openings of Fasteners 13, 13 ', of the support head 12 and the Mounting element 16 have a corresponding Internal gear on for this profile.

0025The division is this Vielzahn- or notch Profiles preferably 15 ° and this is from the manufacturing process Profiles dependent. It is conceivable that smaller angular pitches produced by other manufacturing processes such. B. Sintering can be.

0026In the figure 1 the connecting elements 13 and 13 ' with each other and to the supporting head 12 toward a certain Distance shown. This is in this case only for Clarification of the respective plug-in element. In practice these parts all together tightly. A locking of the Fasteners 13, 13 ', of the mounting member 16 and the Supporting head 12 with each plug-in element 14 is in preferred embodiments by means of a first locking member 18, for example, clamping screw or grub screw run. There are additional facility for locking conceivable such. As a second locking element 19, which in the form of a clamping element may be disposed on the end face of the plug element fourteenth

0027Furthermore, it is possible, the second locking element in the form of a locking hole with pinning or screwing on the end face of the plug element between this and the corresponding member of the respective compound perform.

0028To Erziehlung a finer angular division of the elements with each other is in a further embodiment of a Noniuselement 22 between the male member 14 and a Connecting element disposed. This arrangement, Figure 4 shows in a schematic plan view. The Noniuselement 22 may in be formed shapes. Its principle is that for example different angular pitches between its internal gearing and its external toothing are provided. For this it is required that the Connecting element with the internal toothing to the angular pitch the external toothing of Noniuselementes adapted 22nd

0029Other variations of the different angular pitch are of course conceivable.

0030In an embodiment not shown, the Plug member 14 has a guide pin, whose outer diameter the tip diameter of the internal teeth of the having associated connecting element. The length of this Guide pin extending in the longitudinal direction of the longitudinal axis of the The male element 14 and may different depending on the system have lengths. The guide pin has the task about the male member 14 associated with the connecting elements pull apart or before together to perform so that an advantageous slight pivoting the fasteners against each other is possible, without this for the adaptation process must be kept for each other without guidance. It is also conceivable that the connecting element with the internal toothing in the direction of the axis of the internal teeth a recess , whose inner diameter the tip diameter of External teeth of the male element 14 corresponds to. It is advantageous if the outer diameter of the guide pin and the inner diameter of this Führungsausdrehung in their Dimensions are chosen so that the corresponding part can be easily inserted and pivoted.
