- usually threaded sleeves are used with external thread, which are screwed into an undercut longitudinal groove of a profiled bar and usually serve as an abutment for a screw head of a connecting screw, the connecting screw passes through a through hole of the threaded sleeve and with a screw thread with a counter bearing , in particular a groove block is screwed, which is usually in the profile of a groove orthogonal profile bar.
- a generic profile connection is known from EP 1 574 725 B1, which comprises a threaded sleeve with external thread, wherein the threaded sleeve is provided with a female thread in a special embodiment for producing a butt joint, in which two profile bars abut one another, wherein a connecting screw , as shown in FIG. 7 of the publication, is supported with a screw head on a threaded sleeve which cooperates with the aforementioned threaded sleeve, the connecting screw being connected with its external thread to the internal thread of a threaded sleeve. is screwed and braced in this way, the profile bars against each other.
- the known profile connection several things are perceived as disadvantageous.
- the threaded sleeve is operable or rotatable only from one side.
- the external thread of the threaded sleeve is formed as a forming thread with which a Spanabhub to be avoided when screwing the threaded sleeve in the profile.
- the threaded sleeve is relatively difficult to rotate.
- An alternative threaded connection is known from EP 0 458 069 B1, inner threaded sleeves with a self-tapping external thread being used here, which are more easily rotatable.
- the known threaded sleeve has drive means extending on both axial ends, wherein the two end drive sections are spaced apart by a section of a passage opening which is free of internal threads.
- the external thread of the threaded sleeve ends at a clear distance from the axial ends of the threaded sleeve.
- the scope of the known threaded sleeve is limited - in particular no screwing with the recorded in a profile groove threaded sleeve is possible.
- EP 0 915 262 B1 does not deal with profile connections but with the different technical field of thread inserts.
- the European patent protects a threaded insert with axial continuous hexagonal drive which are formed in an internal thread of the threaded sleeve.
- the threaded insert has an external thread in order to be screwed into a receiving bore, in particular a blind bore, and to provide an internal thread therein, namely the internal thread of the threaded sleeve.
- the present invention seeks to provide an improved profile connection, which is on the one hand easy to manufacture, and on the other hand offers the greatest possible variability in the application. Furthermore, the object is to provide a suitable method for producing the profile connection and a correspondingly suitable threaded sleeve available.
- the invention is based first of all on the idea of providing a threaded sleeve for producing a profile connection which, in addition to a drive means which can be actuated from both sides and an external thread designed as a self-tapping thread, has an internal thread. shows, with which a connecting screw, which can be screwed fixed to each other in a finished profile connection two profile bars, in particular at impact or at right angles to each other.
- the invention provides for the thread pitch of the external thread and the thread pitch of the internal thread to be designed differently from one another in order not to be able to clamp the profile rods as previously by twisting the connecting screw, but instead by twisting the threaded sleeve relative to the then preferably fixed connecting screw , wherein for this purpose the connecting screw is screwed not only with the threaded sleeve, but also with a counter-bearing piece in the second professional bar.
- the threaded sleeve Due to the different thread pitches of external thread and internal thread of the threaded sleeve, the threaded sleeve is thereby adjusted axially within the first profile of the first profile bar relative to the connecting screw and the second, in particular perpendicular to the first profile bar extending second profile bar, which due to the different thread pitches leads to the connecting screw is further displaced axially into the first profiled groove and the second profiled bar is adjusted due to the coupling with the counter bearing piece, in particular against an end face of the first profiled bar, and is thus clamped.
- the threaded sleeve With regard to the specific configuration of the external thread of the threaded sleeve according to the invention, there are different possibilities.
- This should be self-tapping according to the invention that is to say it is such that it has the associated mating thread or internal thread in which preferably formed from a light metal alloy, in particular aluminum alloy formed profile itself by the threaded sleeve is turned down into a first profile of this profile bar profile.
- the threaded sleeve is preferably made of a harder material, in particular steel, designed as the associated profiled bar.
- this can be designed as a cutting and self-tapping thread, whereby the thread is preferably equipped with a corresponding cutting edge, which can be realized by the provision of an interruption or recess in the external thread.
- the external thread it is conceivable to design the external thread as exclusively reshaping and thus not machined thread.
- headless screws i. Grub screws are used, since the clamping principle in a trained according to the concept of the invention threaded sleeve, as explained above, is different from known principles, in which a screw head of a connecting screw is supported on the front side on a female threaded threaded sleeve and with a counter bearing, in particular a sliding block , is bolted in the second profile bar.
- the difference in thread pitches between external thread and internal thread of the connecting screw must be chosen so that by turning the threaded sleeve relative to the preferably not circumferentially moving connecting screw this axially further into the threaded sleeve or in this is adjustable to a second profile bar to brace against the first profile bar via an abutment element. It has been particularly preferred issued when the slope difference is at least 0.05, more preferably at least 0.1, even more preferably at least 0.25, even more preferably at least 0.5. Very particularly preferred is an embodiment in which the external thread is designed as a standard thread, in particular metric thread or inch thread and the internal thread as a fine thread.
- external thread and internal thread of the threaded sleeve there are different possibilities. Particularly preferred is an embodiment in which external thread and internal thread are the same orientation, i. both are designed either as a right-hand thread or as a left-hand thread. In particular, in this case, it is particularly advantageous if, in order to achieve a tension between the first and second profile bar, the external thread has a greater pitch than the internal thread.
- an alternative embodiment is possible in which the external thread and the internal thread are oriented in opposite directions, that is, one of the two threads is designed as a right-hand thread and the other thread as a left-hand thread.
- the thread pitch of the external thread is smaller than that of the internal thread.
- the drive means are formed axially continuous, so that a corresponding tool can be inserted arbitrarily deep into the threaded sleeve in order to rotate it.
- the drive means have two from each other, in particular via an inner Winding section of the passage opening spaced drive ends, which serve for the respective (alternative) interaction with the tool.
- the design of the drive means there are different possibilities.
- the internal thread with a contour deviating from a circular shape, in particular a polygonal contour, very particularly preferably with a hexagonal cross section or a polygonal contour, in particular a torx contour (which only has to be partially realized), the position of the edges ( Corners of the polygonal contour) or the ends of the straight line can end at different radial positions.
- the radially outer inflection points of the multi-round contour can end at different radial positions.
- edges extending axially or, in the case of multi-round geometries, the points of inflection are arranged on the thread root of the internal thread.
- the edges or points of inflection end radially within the internal thread base with radial distance to the thread root or are arranged with radial clearance outside the thread root.
- at least one, preferably a plurality of circumferentially spaced through the longitudinal extension of the threaded sleeve extending, preferably analogous to a Torxkontur rounded grooves, the groove bottom, in particular the above-mentioned inflection point at the level of the internal thread root or with radial distance inside or outside of the internal thread base could be.
- the aforementioned contours need not necessarily be axially continuous, which is advantageous, however, but may also extend inwardly from the axial ends and then be axially spaced apart. It is also possible and preferably provided at both axial ends radially continuous, axially outwardly open recesses watch, in particular a plurality of evenly spaced circumferentially recesses, in particular four, whereby the recesses are formed essentially lying between the recesses crenellations and the tool can axially engage in the recesses.
- Such a design has the advantage, inter alia, that the recesses can be used at the same time for the formation of cutting edges of the threads, in which case it is preferable to dispense with an additional bore for forming the cutting edges, which is not necessary.
- the aforementioned crenellations preferably carry on their inner circumference the internal thread or an internally threaded portion of the threaded sleeve, wherein the internal thread, as already mentioned, preferably extends axially over the entire length of the sleeve.
- the threaded sleeve has a cylindrical envelope contour extending to the axial end.
- the ends have centering, whereby it is basically possible to provide the external thread end with a conical envelope contour. It is also possible, especially in the case of a cylindrically tapering thread, to free a thread on the outside Provide cone section or centering, where, for example, a grading of the end portions is possible, especially in an externally threaded section.
- the internal thread and / or the external thread of the threaded sleeve extends / extend axially in one area of the drive means and / or are provided there, in particular to possibly the majority of the axial extent of the threaded sleeve for the corresponding thread to use, with the aim of minimizing the length and the improvement of the threaded connection.
- threaded sleeve particularly preferred is a variant of the threaded sleeve, wherein the amount of the angle of the thread contour of the external thread of the threaded sleeve forming thread flanks is the same.
- the thread contours are symmetrical in a longitudinal sectional view, preferably in relation to a radial plane, in order to allow trouble-free screwing of the threaded sleeve from both sides.
- the threaded sleeve wherein in addition to the provision of both axial sides operable drive means, the internal thread extends axially continuously between the axial ends.
- the drive means and internal thread, at least in sections, are preferably axially continuous at the same axial height, which depending on the configuration of the drive means causes the internal thread in the circumferential direction is interrupted in sections and / or that the internal thread deviates from a circular shape contour having.
- the invention also leads to a profile connection, comprising at least one first profile bar with a extending in the direction of the longitudinal extent of the profile bar, in particular undercut on both sides first profile groove into which a threaded sleeve according to the invention is screwed, which is characterized on the one hand by the fact that they are from both sides can be screwed by means of a corresponding tool in the profile, wherein the threaded sleeve is simultaneously equipped with an internal thread to (if necessary) with the, preferably at least one end having a drive connecting screw in a screwing interaction.
- the invention provides that the external thread is a self-tapping thread.
- a substantial functionality which can be achieved by the threaded sleeve according to the invention is to screw the connecting screw, which is preferably designed as a grub screw, both with the internal thread of the threaded sleeve and with the internal thread of a counter-bearing piece received in a second profiled bar, in particular a sliding block or a further internally threaded sleeve then by turning the threaded sleeve, in particular in the circumferential direction fixed, that is not twistable rer connecting bolt to achieve a tension of the two profile bars of the profile connection.
