FIELD

The present invention relates to a device comprising two flanges between which a beam or another component can be fixed. Examples of such devices are so-called support shoes and yoke mounts as used in construction engineering and in frame technology. It can be of use if such a device or the component arranged therein is height adjustable.

BACKGROUND

DE 88 01 513 U1 describes a support shoe for receiving and retaining beam ends. The U-shaped reception area of the support shoe is height adjustable and comprises two flanges between which the end of a support or of a beam can be fixed.
DE 20 2008 005 020 U1 describes a mounting system for photovoltaic systems. The mounting system comprises a yoke mount for adjustably fixing a beam onto a support. The beam is received between two flanges of the yoke mount and is fixed in a height and inclination adjustable manner by means of a screwable pivot bolt. The pivot bolt is guided within vertical bolt slots inside the flanges and is moreover supported in two supplemental elements that are clamped against the outer sides of the flanges by means of the pivot bolt. In order to avoid an unintended downward slipping of the pivot bolt within the bolt slots, both at the outer sides of the flanges and at the opposed sides of the supplemental elements, horizontally extending V-shaped toothing are provided to engage with each other in the desired height when screwing the pivot bolt. The V-shaped toothing is thereby co-extruded with the yoke mount produced by means of an extrusion process.

SUMMARY

An aspect of the present invention is to provide a device of the aforementioned type offering improved characteristics with regard to stability and assembly.
In an embodiment, the present invention provides a device for fixing a component with a fixedly arrangeable extrusion part which includes a first flange and a second flange arranged opposite to each other. Each of the first and second flange comprises a slot, and an outer side comprising a first detent toothing. The first detent toothing comprises a plurality of detent teeth directed transversely to the slots. The plurality of detent teeth each comprise an upper flank with an undercut. A bolt is configured to slide into the slot of the first and second flange so as to affix the component in a height-adjustable manner. A first extruded bearing element is arranged at the outer side of the first flange and a second extruded bearing element is arranged at the outer side of the second flange. The first and second extruded bearing elements each comprise a second detent toothing at a side facing the respective first and second flange. The second detent toothing comprises at least one detent tooth comprising a lower flank with an undercut. The second detent toothing is configured to hang with the first detent toothing in at least one indexing position of different heights. The second detent toothing of the first and second extruded bearing elements is configured to connect onto the first detent toothing of the first and second flange via the undercuts.

DETAILED DESCRIPTION

In an embodiment of the present invention, for securing the position of the bearing elements, each flange at its outer side can, for example, comprise a detent toothing comprising a plurality of detent teeth directed transversely to the slots, and that each bearing piece comprises a detent toothing comprising at least one detent tooth at the side facing the respective flange, wherein the detent toothings of the bearing elements engage into the detent toothings of the flanges in one of several indexing positions of different heights. The detent toothings can, for example, be co-extruded with the extrusion part or with the bearing elements, respectively, such that the detent teeth thereof are embodied as straight strands. Other manufacturing methods for the detent toothing and the supports thereof are also possible, such as milling or erosion techniques. For an advantageous height adjustability where the extrusion part is firmly arranged, the detent teeth can, for example, run horizontally and thereafter perpendicularly to the slots. As with detent toothings, the detent teeth may thereby be arranged to be identically and equally spaced within a detent toothing. The regular distance between the detent teeth at the flanges correspond, for example, to exactly one displacement step.
A significant innovation and improvement of the device according to the present invention is that the bearing elements are suspended or hooked into the detent toothing of the flanges by means of their detent toothing, wherefore the upper flanks of the detent teeth of the detent toothings of the flanges and the lower flanks of the detent teeth of the detent toothings of the bearing elements are designed with an undercut. In a perpendicular view onto the front of the respective detent toothing, these flanks or parts thereof are not visible because they are covered by the head of the respective detent tooth or by a projection resulting from the undercut's shape towards the head. For hooking-in, the projections formed by the undercuts of the lower flanks can engage with the undercuts of the upper flanks, i.e., engage behind the projections thereof. It is thereby possible that the undercut and the projection of a flank merge smoothly and are designed very flat. The projections at the lower flanks, in a broad sense, operate as hooks engaging into the undercut of the upper flanks by means of hooking-in, thus forming a hook connection that is stable without further action solely by means of the bearing elements' gravity. Independently thereof, the bearing elements may additionally be secured axially or clamped against the flanges.
The present invention has numerous advantages. In contrast to the V-shaped toothing known from the prior art, a downward slipping of the bearing elements at the flanges is eliminated, even when not clamped or with highly loaded bearing elements. A loosening of the hook connection is not possible without contemporaneously lifting the component by a small amount. The contact areas of the detent toothings can, for example, be larger than the contact areas of the bolt such that the transferrable forces only depend from the material cross-section of the bolt. A further advantage is that the bearing elements are self-suspending at the flanges during the assembly procedure. Even a light nudging of the extrusion part does not result in a loosening of the bearing elements off from the flanges. For stepwise approximation of the desired indexing position, the bearing elements do not have to be pre-tightened against the flanges as with the prior art. In fact, it is now sufficient to arrange the bearing elements in another indexing position by repeated hooking-off and hooking-in procedures. All advantages are particularly beneficial if several of the devices according to the present invention are used for a system of components, for example, for several supports of a frame. All components can thus be adjusted first for height and then finally be assembled together.
In an embodiment of the present invention, the bearing elements and the bolt can be axially secured against each other, for example, by means of cotter-pins, such that neither the bolt nor the bearing elements can become loose from the extrusion part. The bearing elements can not only be secured axially but can, for example, be clamped against the flanges by using clamping means provided at the bolt. The bolt can thus, for example, be a threaded bolt with nuts thereupon clamping the bearing elements against the flanges. A simple head screw with a nut is, however, particularly advantageous therefor.
In an embodiment of the present invention, the extrusion part can comprise a co-extruded mounting base with which it can be fixed on a mounting site, for example, on a horizontal base or on the head of a support. For adjusting the height of the bolt, the slots in the flanges can, for example, be provided perpendicular to the mounting base. The flanges can furthermore form a U-profile shape together with the mounting base or with a part thereof. In case both the detent teeth at the flanges and the mounting base are co-extruded with the extrusion part, the manufacturing process will cause the detent teeth to run parallel to the mounting base.
In an embodiment of the present invention relating to the detent toothings, the shape of the upper flanks of the detent teeth at the flanges and the shape of the lower flanks of the detent teeth of the bearing elements can be fitted counter-shaped, such that the detent toothings there engage with each other there with large load bearing areas and small play or, for example, free of play. The detent teeth of the one detent toothing may further each comprise front surfaces and the free spaces between the detent teeth of the other detent toothing may each comprise back surfaces that form counterforms matching with each other and abutting each other in the respective indexing position with large contact areas. The front surfaces and the back surfaces can thereby, for example, be designed planar and in parallel to the front plane of the detent toothings or to the flanges, respectively. If both the said flanks and the front and back surfaces comprise matching counterforms, the tooth pairings under engagement each advantageously create a form closure positive-negative-unit, wherein the detent teeth are designed narrower than the free spaces between the detent teeth so that the detent toothings can be engaged into each other.
In an embodiment of the present invention, the upper flanks of the detent teeth at the flanges are embodied as lead-in slants declining towards the flange for the detent teeth at the bearing elements. The detent toothings of the bearing elements can thereby run in with a combined side and downwards movement into the detent toothings of the flanges in a sliding manner. It is thereby advantageous if the bearing elements can themselves tend automatically against the flanges into a final indexing position under sufficiently high load of the component or solely by their own weight of gravity. In order to keep friction as low as possible, both the upper and the lower flanks can, for example, comprise planar sections at which the flanks can slide onto each other in parallel until reaching the final indexing position. For the function of lead-in slant, it can be advantageous when the upper flanks or their planar sections are undercut or inclined in an angle within a range of between 1° and 5°. The lower flank can then be inclined under the same angle. Contrary to gear toothings, the undercut of the flanks can moreover already begin at or in the near to the, optionally rounded, edges of the front surfaces of the detent teeth. It is thus possible that the flanks are undercut over their entire cross-sectional length or over the mainly part thereof which has proven to be advantageous with the lead-in slant described above. If the detent teeth are undercut at the flanges on both sides and in the described way, they can comprise a trapezoidal cross-section in which the broadest site is at or near to the front surface. Examples include, for example, cross-sections of symmetrical trapezoids. The detent teeth at the bearing elements are advantageously also shaped this way. The edges or cross-sectional corners of trapezoidal detent teeth may of course be rounded in a suitable manner. Accordingly, in case of the afore-described matching counterforms, a Z- or S-shaped cross-section of the contact areas can be determined.
Though it is principally sufficient to embody the detent toothings at the bearing elements each with only one detent tooth, said detent toothings can, for example, also consist of several detent teeth. However, a higher number of detent teeth can, for example, be provided at the flanges than is provided at the bearing elements. For the bearing elements, it can be of additional advantage if not only the lower but also the upper flanks of the detent teeth are undercut. The bearing elements can thereby be alternately used in two positions rotated by 180° which facilitates assembling. It is of particular advantage if the flanks of the detent teeth are thereby undercut at the bearing elements in symmetrically, in particular in the aforementioned trapezoidal shape.
The device according to the present invention can, for example, be used as a support shoe or yoke mount for use in construction engineering or frame technology. The device can accordingly be fixed on a base, the head of a support or other mounting frames. The component fixed within the device is not only height adjustable, but tiltable as well, because the bolt may additionally operate as a joint axis.
The arrangement shown in various perspectives in FIG. 1 to FIG. 3 comprises a device according to the present invention, the device comprising a support shoe 1 comprising two plate- like flanges 2 and 3 facing each other. Between the two flanges 2 and 3, according to the principle of a yoke, the end of a vertical support 4 is fixed by means of the screw 5 of a screw connection. The screw 5 is hereby guided in a height variable manner within two aligned longitudinal holes 6 and 7 in the flanges 2 and 3 and is furthermore supported within two extruded bearing elements 8 and 9 that are clamped between the outer side of the flange 2 and a nut 23 on the screw 5 or between the outer side of the flange 3 and the head 24 of the screw 5, respectively, in a height adjustable manner. The screw 5 acts as a joint axis and penetrates the end of the vertical support 4 such that the vertical support 4 can also be fixed in other angles of inclination or positions of rotation between the flanges 2 and 3.
The support shoe 1 is cut off from an extruded profile strand and has been further processed. In addition to the flanges 2 and 3, it comprises a plate-like mounting base 20 at which the support shoe 1 is arranged on a horizontal base not shown here by means of a dowel anchor 21. Hereby, an elastic mat 22 serves for corrosion protection as well as for compensating small unevenness on the base. As can particularly further be seen from FIG. 3, the flanges 2 and 3 are arranged at a distanced from and in parallel to each other and are formed upright standing on the mounting base 20. Accordingly, the flanges 2 and 3 form a U-profile shape together with the relating section of the mounting base 20 that is arranged between the flanges 2 and 3 and at which the dowel anchor 21 is attached. The mounting base 20 is continued laterally beside the U-profile shape in order to enhance the contact area. The longitudinal holes 6 and 7 contained within the flanges 2 and 3 are also arranged upright standing to the mounting base 20, and are thus arranged vertically within the arrangement. Alternatively, the screw 5 could also be guided in a height variable manner within longitudinal holes having a small inclination.
Like the support shoe 1, the bearing elements 8 and 9 are manufactured in an extrusion process and have then been further processed. Other manufacturing methods, such as milling or erosion techniques, are also possible for bearing elements 8 and 9 as well as for the support shoe 1. In order to avoid unintended downward slipping of the bearing elements 8 and 9 at the flanges 2 and 3, it is provided that each flange 2 and 3 comprises at its outer side a detent toothing 10 or 11, respectively, each having a plurality of detent teeth 12 arranged transversely to the longitudinal holes 6 and 7, and each bearing element 8 or 9, respectively, comprises at the side facing to the flange 2 or 3, respectively, a detent toothing 13 or 14, respectively, each having a plurality of detent teeth 15, wherein the detent toothings 13 or 14, respectively, of the bearing elements 8 and 9 engage in one of several indexing positions of different heights into the detent toothings 10 or 11, respectively, of the flanges 2 and 3 after having been set on or in laterally.
The detent toothings 10 and 11 at the flanges 2 and 3 have been co-extruded with the support shoe 1 such as the detent toothing 13 and 14 has been co-extruded with the bearing elements 8 and 9. Accordingly, the detent teeth 12 or 15, respectively, are formed as straight strands that runs in parallel to the mounting base 20 and thus horizontally within the arrangement. As is common for toothings, the detent teeth 12 of the detent toothing 10 or 11, respectively, are all identical and equally distanced from each other. This also applies for the detent teeth 15 of the detent toothing 13 or 14, respectively, wherein the detent toothings 13 and 14 are interrupted at the bearing elements 8 and 9 in the penetration area of the screw 5. Furthermore, the toothings 10 and 11 are continued at the flanges 2 and 3 above and below the longitudinal holes 6 and 7, such that the entire height of the longitudinal holes 6 and 7 can be used for adjusting the screw 5. The distance of the detent teeth 12 at the flanges 2 and 3 thereby corresponds to one indexing step and, in this exemplary embodiment, is a little bit larger than one millimeter. At both flanges 2 and 3 there are about 15 corresponding possible indexing positions.
To further illustrate the height adjustability, FIG. 4 and FIG. 5 show the arrangement during an assembling procedure, wherein the bearing element 8 has not been clamped against the flange 2 by means of the screw 5 and the nut 23. The position shown in FIG. 4 thereby corresponds to a middle indexing position in which the screw 5 is arranged in approximately the center space between the upper and the lower boundaries of the longitudinal holes 6 and 7. Opposite thereto, FIG. 5 shows the position of the uppermost indexing position. For final assembling, these two arrangements, the nut 23 is screwed such that also the toothing 13 of the bearing element 8 engages with the toothing 10 of the flange. This mutual engagement of the detent teeth can be seen in more detail in detail D1 according to FIG. 6. In order that the detent toothings 13 or 14, respectively, of the bearing elements can engage with the detent toothings 10 or 11, respectively, at the flanges 2 and 3 when having been set on or in laterally, the detent teeth 12 and 15 are designed less wide than the free spaces therebetween.
An innovation and improvement of the present invention is that the bearing elements 8 and 9 are suspended or hooked into the detent toothing 10 or 12, respectively, of the flanges 2 and 3 by means of their detent toothing 13 or 14, respectively. Therefore, the detent toothings 10, 11, 13 and 14 are formed correspondingly in a particular manner which is further shown in the details D1 to D3 according to FIG. 6 to FIG. 8. Thus, one of the detent tooth 12 at the flange 2 is shown in detail D2 according to FIG. 7. Together with details D1 and D3 it can be seen that the detent teeth 15 at the bearing element 8 are identically formed and are arranged there only in a mirror inverted manner. The specific feature of the detent toothings 10, 11, 13 and 14 can be seen from that the upper flanks 16 of the detent teeth 15 at the bearing elements 8 and 9 are designed with a small undercut. This means that, in a perpendicular view onto the front of the respective detent toothing as shown in FIG. 2, these flanks 16 and 17 are covered at least partly by the head or the broadest site of the detent teeth 12 or 15, respectively. It is therefore possible that the bearing elements 8 and 9 are arranged hanging in the relating indexing position at the flanges 2 and 3. In addition thereto, the relating opposite flanks 30 and 34 are also undercut in the same way.
As can particularly be seen in detail in FIG. 7 and FIG. 8, the detent teeth 12 and 15 comprise a trapezoidal cross-section with rounded corners. The shape of this symmetrical trapezoid is encircled by the dash-dotted lines in FIG. 7, wherein the front surface 31 of the detent tooth 12 lies in parallel in the front plane of the detent toothing 10 and the flanks 16 and 27 are undercut with an angle of 1.5°, i.e. having an angle α of 89.5° with the front surface 31. By means of the undercuts 36 of the lower flanks 17 and of the upper flanks 16, correspondingly positively formed projections are formed towards the respective tooth head, the projections engaging with each when suspended or hooked in. Though the undercuts 36 and the projections of the respective flank 16 and 17 smoothly merge into each other and are designed very flat, the projections of the lower flanks 17 operates, in a broad sense, as hooks engaging with the undercut 36 of the upper flanks 16 such that a hook connection is formed which is stable without further action solely by the gravity of the bearing elements 8 and 9. As the flanks 16 and 17 of the detent teeth 15 are undercut at the top and at the bottom of the bearing elements 8 and 9 symmetrically, the detent teeth 15 can be alternately used in two positions rotated by 180°.
In a position shortly before reaching the final indexing position as is shown in detail D3 according to FIG. 8, the upper flank 16, the front surface 31 and a back surface 32 limiting the teeth interspace on the side of the detent teeth 12 facing towards the corresponding surfaces on the side of the detent teeth 15, that is the lower flank 17, a back surface 37 limiting the teeth interspace and the head surface 33. All these surfaces are embodied as matching counterforms, whereby a connection free of play is achieved, the connection comprising a sufficiently large load bearing and contact surface. The detent toothings 10 and 13 or 11 and 14, respectively, thus compose a form closure positive-negative-unit per tooth pairing wherein only the free spaces between the detent teeth 12 and 15 are wider than the detent teeth 15 and 12.
As can be further seen in FIG. 8, the upper flank 16 of the detent tooth 12 operates as a lead-in slant declining towards the flange 2 for the detent tooth 15. The lead-in slant thereby coincides with the upper leg of the aforementioned trapezoid and is thus inclined with the angle of 1.5° relative to a horizontal 38. As a result thereof, the detent toothing 13 of the bearing element 8 can slide with a combined lateral and downwards movement illustrated by means of the path arrow 35 along the flank 16 into the detent toothing 10 of the flange 2. As the lower flank 17 at the detent tooth 15 comprises a matching counterform, i.e, it is planar as well and inclined at the same angle, only minimal friction exists between the flanks 16 and 17 such that the bearing elements 8 and 9 themselves automatically tend towards the flanges 2 and 3 solely by their weight gravity or at least by a sufficiently high load of the support 4, and into the final indexing position, i.e., they perform the movement along the path arrow 35. The flank 16 operates as the lead-in slant and thus has in a kind of self-tightening function for the bearing elements 8 and 9 whereby even in case of a loosening of the screw connection, the bearing elements 8 and 9 are further pressed against the flanges 2 and 3.
At the inner surfaces of the flanges 2 and 3 there is provided a further toothing 26, each of which has again been co-extruded with the support shoe 1. One of these toothings 26 and its waveform is shown in detail in FIG. 6. By means of the toothings 26, the rotational friction between the support 4 and the flanges 2 and 3 can be increased if tightening the screw 5 and the nut 23 is done to such an extent that the inner surfaces of the flanges 2 and 3 are pressed against the adjacent outer surfaces of the support 4. The gap seen in FIG. 6 between the toothing 26 and the outer surface of the support 4 hereby disappears. In this way, the support shoe 1 can clamp the support 4 additionally rotatorily, i.e., it can load torques. The rotational friction between the support 4 and the support shoe 1 can be further increased by providing a similar toothings at the support 4, the toothings extending transversely to the toothings 26 or crossing them. If the strain of the screw connection is then increased in such a way that the toothings impress each other under plastic deformation, a torsionally rigid compound is obtained. Such a clamping of the support may alternatively also be very low or be avoided at all, whereby the device acts like a tilting bearing in which the support 4 is supported at the screw 5 in a rotationally free manner. The height adjustability of the screw 5 by means of the bearing elements 8 and 9 is not affected thereby, as the afore-described hook connection between the detent toothings 10 and 13 or 11 and 14, respectively, is stable without further action, i.e., without any lateral tightening. A disengaging of the hook connection is not possible without contemporaneously lifting the support 4 by the amount of the undercut 36. Instead of a screw connection, a bolt at which the bearing elements 8 and 9 may be secured only axially, for example, by means of cotter pins, may also be provided.
The present invention is not limited to embodiments described herein; reference should be had to the appended claims.
