Definitions
- the invention relates to an assembly with a male threaded threaded spigot and with a screw which can be screwed onto the threaded pin and a comprehensive assembly this fastening device for fastening a fitting to a hollow profile.
- Such an assembly for mounting a fitting part on a provided with a superior profile part hollow profile is known for example from DE 35 21 783 C1.
- the screw element has a threaded bore into which a fastening screw passing through the fitting part in a bore can be screwed, so that when the fastening screw is tightened, the fitting part is pulled against the screw element.
- this screw comprises a circumferential knurling whose tips are slightly above the otherwise lindrischen and in its diameter to the diameter of a bore provided in the profile corresponding circumference of the screw member protrude.
- the invention is therefore based on the object to provide an assembly, in particular for the attachment of a fitting to a hollow profile, in which the desired rotational inhibition of the screw is achieved, without the interaction with a further component or the attack of a rotation inhibiting tool is required.
- the screw according to the invention has a bore whose diameter is smaller than the outer diameter of the external thread. Furthermore, according to the invention, the ratio between the diameter of the external thread and the diameter of the bore and / or the materials selected for the threaded pin and the screw element and / or the thread geometry selected such that for unscrewing the screw on the threaded pin or for screwing the threaded pin in the bore of the screw a predetermined torque is required.
- the invention is based on the surprising finding that, by adapting one or more of the above parameters, the screwing element is screwed onto the threaded pin or, if the element comprising the bore is stationary and the threaded pin is rotatably arranged, the screw threading element the bore of the screw torque required within wide limits can be predetermined.
- the torque required for screwing in or out can be selected such that it is greater than the maximum torque acting on the later use of the assembly between the threaded pin and the screw element, which - finds the module for fastening a fitting part use - usually acts when tightening or loosening a fitting passing through the fastening screw on the screw.
- the invention is further based on the particularly surprising finding that even the loosening torque required for releasing the screw element from the threaded pin corresponds approximately to the value previously required for screwing the threaded pin and screw element together, so that the assembly according to the invention provides a rotational lock between the threaded pin and provides the screw in both directions of rotation.
- the bore has a threaded area with an internal thread complementary to the external thread, which is shorter than the length over which the threaded pin is in the bore in the screwed-in state.
- the length of the threaded portion in the screw is about 5 mm, on the one hand a simple assembly of threaded pin and screw is ensured, on the other hand a load capacity of the threaded connection is effected, which ensures in most cases that further rotation of the threaded pin penetrates into the unthreaded area of the bore and does not tear the outer and / or inner thread.
- the threaded pin means for Dreharret ist and the screw on means for the approach of a turning tool. It is understood that, in the event that the screw element fixed and the threaded pin are rotatable, the means for rotational locking on the screw and the means for attachment of the rotary tool are formed on the threaded pin.
- the means for Dreharret ist may - particularly preferably - include a bearing plate, the form-fitting with a contact surface, which on another component or on another assembly, such as a hollow profile, on which the threaded pin or the screw is to be determined, engageable are.
- these means can be formed by providing at least two threaded pins or screw elements on a contact plate, which engage in separate, provided in the component, spaced-apart holes.
- the means for the attachment of a turning tool preferably comprise a hexagon socket, since in this way the screw element or the threaded pin can be provided with a rotationally symmetrical, in particular cylindrical outer contour, whereby the manufacture and assembly of the assembly according to the invention are facilitated.
- the assembly according to the invention is particularly suitable if the screw fasteners for this device or this module , very particularly preferably in the form of a threaded bore, in which then a fastening screw can be screwed.
- the screw at the end facing the fitting a radially projecting beyond the outer circumference of the screw collar whose outer diameter is greater than the inner diameter of a provided in the fitting part facing hole for passage of the screw is.
- the end position of the screw element to be screwed onto the threaded pin can be defined as a position in which the lower edge of the collar bears against the outer surface of the wall comprising the perforation.
- the free end face of the collar can then form a contact surface for the fitting part, so that the risk of bending the wall when tightening the fitting in a hole passing through the fastening screw does not exist.
- this fastening device in which the outer diameter and the height of the contact collar on the inner diameter and the depth of the first stage is adapted to a extending from the mounting side of the mounting part stepped bore in the fitting part, such that in the assembled fitting part of the lower edge of the collar lies with the mounting side in a plane. Due to this measure, it is ensured that there is no gap between the outer surface of the wall and the side of the fitting part facing the latter, which on the one hand would have a negative effect on the optical appearance, on the other hand would promote the setting of impurities.
- the direct contact of the fitting part on the wall achieved on the basis of this development means that the holding forces achieved with the fastening device are increased.
- Fig. 1 is a side perspective view of this embodiment with not screwed on the threaded pin screw elements
- Figure 2 shows the same embodiment in a partially sectioned view of Figure 1 from above, also with untwisted on the threaded studs screw elements ..; such as

- Fig. 5 shows the same use in a partially sectioned view of FIG. 4 from above, with not screwed on the threaded pin screw elements, as well as Fig. 6 shows the same use in a Fig. 5 corresponding view, but with screwed on the threaded pin screw elements and with dashed lines, mounted fitting part.
- the assembly 100 shown in the drawing comprises three threaded pins 1, which are perpendicular to the longitudinal axes S spaced rotatably on a bearing plate 2, in particular by welding, are attached.
- the threaded pins have external threads 3, which are formed in the exemplary embodiment described here as an M8 control thread.
- Both the threaded pin 1, and the contact plate 2 are made of the stainless steel material 1 .4567 or 1.43.01.
- the assembly 100 has three screw elements 4, wherein each of these screw elements - as is apparent from Fig. 1 - one of the threaded pin 1 is assigned.
- the screw elements 4 are made in the embodiment described here from the aluminum material EN-AW-6082-T6. They have a substantially cylindrical outer shape. At the end facing the respective threaded pin 1, a chamfer 5 is provided in each case in order to facilitate the insertion of the screw elements 4 into a perforation of a component not shown in the drawing. The end of each screw element 4 opposite the chamfer is formed by an abutment collar 6 protruding radially beyond the cylindrical part of the screw element 4.
- the screw element 4 has, in its region facing the threaded pin 1, a bore 7, which is designed as a blind bore.
- the diameter of the bore 7 is about 7.3 mm.
- a hexagon socket 10 To the bottom of the hole 9 through a hexagon socket 10 is provided for attacking a rotary tool, not shown in the drawing. Further, the bore 9 has an internal thread 1 1, which extends from the open end to close to the hexagon socket 10.
- Fig. 3 which shows the assembly 100 in the assembled state
- the screw 4 is turned on the length L on the threaded pin 1, so that the external thread 3 had to train the extension of the internal thread 8 in the bore 7 itself
- a torque of about 15Nm is required for this purpose.
- a loosening torque is required about a value of the same order of magnitude, where with untmosenden moment the torque is required, which is required to release the screw 4 from the end position generated during tightening.
- To turn down the threaded pin 1 then only a smaller torque is required.
- the assembly according to the invention is characterized inter alia by the fact that for fastening and loosening a not shown in the drawing, engaging in the bore 9 fastening screw for fastening further, not shown in the drawing components or Assemblies required rotational inhibition is achieved without this additional measures or components are required.
- the assembly 100 is used to mount a fitting B, indicated only by dashed lines in Fig. 6, on a hollow profile 12, the edge of a fixed frame or hingedly mounted on the frame Can form wing.
- the hollow profile 12 has a mounting wall 13 shown on the right in Fig. 4, on which the fitting B is to be mounted.
- the mounting wall 13 is formed in the embodiment shown in the drawing of a plastic web, which is firmly connected to adjacent profile parts of an aluminum material.
- the inner diameter of the outer diameter of each of a screw element 4 described below is adapted such that the latter is substantially free of play in the respective bore 14 can be inserted.
- profile wall 15 are also aligned in the drawing three holes aligned in the drawing incorporated into the drawing, which serve the passage of a e- b boss further described below threaded pin 1.
