  • the shank of the support bolt and the socket in which he sits are connected by means of shrinking, wherein the upper end of the sleeve rests on the head portion of the support bolt.
  • this known connection device there is the disadvantage that the absolutely firm connection between the shank of the support bolt and the sleeve causes any triggering of the supporting bolt inevitably leads to a rotation of the socket. For this reason, when tightening the screw (when screwing the load) rotates the sleeve and thus also attached to the bottom of the socket, resting on the top of the load flange with the rotation of the screw.
  • connection device from the US 5 248 176 A are used instead of a support pin holding sleeve two axially successively connected sleeves, each of which is provided at its axially outer end with a radially projecting annular flange.
  • the support pin is freely movable within these formed by the two holders holder relative to these and not attached to them, which fixes the disadvantages when screwing the load to be attached, in the above-described known connection device by the solid connection between these parts used there occurred.
  • connection device has a total of a relatively complicated structure with a plurality of individual elements.
  • connection device from the US 4 641 986 A Only a central sleeve is used, in which the support pin is rotatably mounted, wherein the support pin at its upper side via an intermediate ring at the upper end of the bushing supporting bolts at the lower end of the socket in an enlarged recess mounted there by means in the region of its Anschraubgewindes for fixing load is inserted snap ring secured against pulling upwards.
  • a connecting device in which a support pin rotatably seated in a socket which is cylindrical in its adjoining his bolt head area and in its lower portion has a threaded portion whose outer diameter corresponds to the outer diameter of the cylindrical shaft portion.
  • a cylindrical sleeve on its outer circumference is screwed, which in turn projects into a radially enlarged recess in the through hole of the bush and slidably abuts with its outer periphery on the inner walls of the recess.
  • the sleeve Since the sleeve is screwed onto the threaded portion of the support bolt, it also follows its rotational movements when a load is to be screwed on the axially projecting end of the supporting bolt. In this case, a friction then occurs between the outer circumference of the sleeve and the inner surface of the bush, which leads to the occurrence of frictional forces.
  • the rotating sleeve then transmits the frictional forces to the bush, from which they, in particular in the final phase of the Anschraubvorgangs, transmitted at the bottom of the surface of the load to be screwed and at the opposite top of the lower end flange of the socket on the underside of the housing of the connecting device become.
  • a certain proportion of the prescribed tightening torque must be applied again for overcoming these frictional forces in this connection device.
  • this known connection device is relatively complicated in their cultivation as well as in their assembly.
  • the invention proposes a terminal device which has a simple structure and in which almost no share of the prescribed tightening torque for the additional overcoming of frictional forces between the bolt to be screwed and other elements of the device must be spent in a screwing a load.
  • connection device of the type mentioned above in that the shaft of the support bolt at an axial distance from the upper end of the bush as an engaging part integrally forms a shaft portion with a radially enlarged shaft diameter in the region of the recess, under radial and axial play in the recess protrudes, where: d 1 > d 2 > d 4 , where d 1 denotes the inner diameter of the recess, d 2 the radially enlarged shaft diameter of the enlarged shaft region and d 4 the first diameter of the through hole.
  • the shaft portion with increased shaft diameter consists of an external thread whose threads form the radial enlargement, and the bushing portion with the first diameter of an internal thread corresponding to the thread on the shaft portion enlarged shaft diameter.
  • the support bolt is initially screwed with its the shaft portion enlarged shaft diameter forming external thread through the internal thread of the bushing portion with the first diameter when mounted in the device until the external thread has passed completely through the internal thread. Subsequently, the support pin in the through hole of the socket without further rotation can still be moved axially until the head part of the support bolt rests on top of the socket or on an intermediate shim.
  • a particularly simple and therefore cost-effective embodiment of the invention is that the external thread, which represents the shaft portion with increased shaft diameter, is formed directly from the thread, which is provided on the load-facing end portion of the support bolt for screwing the load, wherein the diameter of the remaining portion of the shank of the supporting bolt is smaller than the core diameter of this external thread.

  • the support pin in the assembled state remains slightly rotatable relative to the socket, but can no longer be removed from the socket without additional effort and is therefore always held in this.
  • the support pin is first inserted so far into the through hole when inserted into this until its cylindrical shaft portion sits with enlarged diameter at the beginning of the through hole, the latter, according to a further preferred embodiment of the invention, at its upper end with a rounding or a chamfer is provided, whereby a shrinkage of the shank portion of the supporting bolt is facilitated with a larger diameter.
  • the shaft area of enlarged diameter is cylindrical, then it is then, for. B. by means of a suitable plastic hammer, through the narrowed part of the passage opening with force, until it has entered into the recess of the annular groove with an enlarged inner diameter. It is advantageous to keep the axial length of the shaft region with an increased diameter as small as possible in order to lower the force required when driving through the upper input region of the passage opening. However, it must be ensured that in the assembled state of the shaft portion accommodated in the enlarged diameter of the support bolt in the annular groove also sits with the required axial clearance, which may possibly be relatively small, but a slight and unimpeded twisting of the support bolt in the Passage opening must be ensured.
  • the support bolt is formed with its shaft of a material having a greater strength than that of the bushing, which facilitates the drive through the narrower opening area of the passage opening.
  • the enlarged diameter of the shaft portion of the supporting bolt is only radially so far protruding chosen that a driving of the support bolt with a moderate force through the narrower range of the passage opening is readily possible, it was found to be advantageous if the other nominal diameter of the through hole from the outer diameter of the cylindrical shaft portion with an enlarged diameter radially to 0 , 1 to 0.075 mm is covered. It can be seen that even small differences in diameter lead to a sufficiently good axial fit of the area of the support bolt of increased diameter relative to the bushing portion with the first diameter and ensure sufficient axial support against unwanted running out of the support bolt from the through hole.
  • a further advantageous embodiment of the invention is also the fact that the support flange is mounted in the housing so that it is self-locking supported in each of its possible pivoting positions.
