Description

The invention relates to a screw-on hinge for profile rails, consisting of two hinged together NEN hinge lobe, each at least one Have fasteners to the hinge tab with the with an opening and a longitudinal groove rail to connect. Screw-on hinges of the above Are kind already known.

The catalog of the company EMKA Beschlagteile GmbH & Co. shows KG, 42551 Velbert, page C 191, 1991, a screw-on hinge of the specified type, this screw-on hinge either with grub screws is provided in order to be connected to a profile rail or the like or has a breakthrough into which a sink screw can be inserted to the hinge part z. B. to attach to the profile.

The known screw-on hinge has two setscrews or two openings per hinge flap, and so on an anti-rotation lock between the hinge flap and the profile slide ne to get cabinet frame, door leaf or the like. So that it is required the component on which This hinge cloth is to be attached with two corrections to provide aligned breakthroughs through which the Insert the grub screw and then using Screw nuts can be attached or through the ent talking cap screws that can be passed then also be fixed with screw nuts.  

The need to double-lock such to provide existing set screws or cap screws, increased the workload, for example in the profile rail at least two openings for each hinge flap must be attached.

EP 0 283 984 A1 describes a coupling system for profiles elements of housings, door and window frames or the like described, in which the coupling element with a Has foot and a head provided pin, the Head penetrates into the groove of the profile rail and the share flap against the profile rail. However, there is no ne sinking, but a breakthrough to take the foot present in the hinge lobe and a second loading is missing Fixing possibility, since the contact surface is not flat, son which is designed as a corner.

Another problem arises when the distance between the profile rail to be connected by means of a hinge depending on the application. To it was previously necessary to adapt each differently to provide shaped hinges, each with different Chen distances of the openings from the hinge axis. Depending on the setting accuracy, it was previously necessary to use a larger number of different hinges in stock to keep what is extremely costly.

The object of the invention is therefore the known hinge to improve it so that it is mon can be tiert. Furthermore, one should be as fine as possible Adaptation of the distance of the hinge axis from the fastening points on the profile rail be made possible without a large number of un Different sized hinges is required.

The screw-on hinge should be particularly suitable, aluminum minimum profiles used for partitions, machine cladding u. Ä. are used to connect to each other in an articulated manner, if necessary also profile rails with different grooves broad should be interconnectable.

The task is solved by the fact that in the profile rail adjacent contact surface of the hinge flap one Depression to accommodate the foot, one foot and one  Head having pin or block is provided, the kind of that with his head in the groove of the profile rail penetrating pegs on the one hand and either a second peg or a fastening screw or a grub screw on the other hand, the hinge tab with respect to the profile rails fix the axis. These measures make it possible to second fastening screw or on a second thread and the necessary second breakthrough in the To omit profile rail or the like, so that despite use only a single hole with the appropriate fastening cover screw or grub screw of the hinge tab Lich the profile rail axis is fixed, so not in can twist unintentionally.

The fact that according to a development of the invention Head of the pin on a rectangular cross section points, d. H. with a longitudinal extension and a (shorter) Lateral extension, it becomes possible with a single head the fixation of profile rails with two different ones To be able to make groove widths, namely with a first Groove width, that of the smaller rectangle width of the cross section corresponds, and a second groove width that the larger Rectangular width of the tenon head corresponds.  

For this purpose, only the head needs to be turned by about 90 ° to be rotated, or inserted rotated by this angle to become.

By using different head sizes, each with different dimensions (e.g. cross-sectional size of the head 8 × 10 mm or 7 × 9 mm), further profile rail groove widths can be used without the need for a different screw-in hinge, just a pin with a different head is to be used.

To the pin with his foot in the hinge tab To be able to place this could be a circle in cross section shaped foot, which then in a corresponding circle shaped depression inside the hinge flap could be brought.

However, it has proven to be cheaper to use one of the Circular shape deviating cross-sectional shape for the foot of the To use pin, especially one in the cross cut cross-shaped foot, the cross profile of the for the The intended cross-section of two intersecting There are rectangles whose length is greater than their width.

This measure results in one The pin is secured against rotation within the rag brought, corresponding profile having depression, what but also with other, non-circular cross would be possible. The cross-shaped cross section has but another advantage in that he did it possible to provide several indentations for the pin, and so close together that these depressions partially overlap without, with a suitable arrangement, the anti-rotation and fixation is lost. You educate then the one for the grub screw or the screw bolt in the Rag provided breakthrough so that it is a  (preferably aligned perpendicular to the joint axis) Elongated hole, it succeeds, by means of these multiple ones different distances of the attachment point to realize the hinge axis without this Different screw-on hinges are used for this purpose would. It is then only necessary to insert the spigot into one insert the appropriate recess, remove the hinge and then the second fixation point cause z. B. the mounting screw or Provide grub screw with a fastening nut and in Elongated hole is clamped (alternatively, a second would come Cones into consideration).

The stability is increased when both sides of the breakthrough Depressions are provided or on both sides of the elongated hole Groups of depressions. Cheap is a symme trical arrangement, such that, for example, symmetry with respect to the center bisector of the hinge, the center bisector perpendicular to the hinge axis runs.

Another axis of symmetry can be the hinge axis.

It has already been said that to achieve one if possible narrow grading of the distance setting it may be convenient if the depressions partially overlap. It is cheap if the depressions overlap in such a way and overlap that two are diametrically opposed overlying recesses formed by the cross profile are formed, in which the corresponding, from the foot of the Spigot formed surfaces or projections of the cross profile of the trunnion foot or intervene.  

One has proven to be a particularly favorable construction Proven arrangement, in which several depressions each around such a grid dimension (or a multiple thereof) in axial direction (of the elongated hole) and / or perpendicular to it are arranged so that there are different distances between the sink centers and the hinge axis result. The grid dimension can be defined in that the twice the grid dimension is the dimension by which the rectangle, the the cross shape is longer than it is wide.

The depressions can be essentially in a line lie diagonally in the direction of one of the outer Point corners of the respective hinge tab to the grid like, in z. B. constant removal steps Displacement of the pin from a first, next to the Position hinge axis up to an nth (e.g. 5th), furthest from the axis Position.

The cruciform depressions can essentially also lie on lines that are perpendicular to the hinge joint axis run. It has been shown that it is beneficial if several, e.g. B. three cruciform depressions on one line near the outer hinge edge arranged mutually and / or partially overlapping are and if again several, e.g. B. two more cross shaped depressions on a second line at a distance the former depressions are arranged, namely slightly offset against this, for example by one half a grid dimension or a multiple of a half grid measure.

Sometimes it is useful to have the finer desired Gradation, between the two rows of depressions still to provide a third series of depressions between these two aforementioned rows is arranged.  

The arrangement with several rows of depressions is especially suitable for larger hinge tabs, the more Space for the arrangement of such depressions Make available and also have greater stability.

It has also proven to be beneficial to use the rags in same width but different length the linkage area of these flaps being kept identical can be, so that a short rag with one long rag, two long rags or two short rags Rag can be combined with each other. On short lobes can be a single-line, diagonally arranged Have arrangement of depressions during a longer one Rags several rows, e.g. B. perpendicular to the hinge axis aligned, could carry from depressions.

Through this different combination options he possible the hinge designed according to the invention extraordinary variability in the choice of Ab between the attachment point of the profile bar and the hinge axis, while maintaining it the advantage that only a single mounting hole for every hinge tab in the profile rail is necessary.

So it is possible, for example, to shill with them derenden embodiments in increments of 1 mm intervals between the fastening points of two rails realize that between, for example, 33 and 62 mm lie.

The depressions preferably have a depth that approximately equal to the narrower width of the cross shape forming rectangle is, for example, 3 mm.

As a material for the hinge as well as for the pin plastic or die-cast zinc has proven itself.

The invention is explained below with reference to exemplary embodiments play explained in more detail, which are shown in the drawings are.

Fig. 9 two perspective walls shown in perspective, which are delimited by two interconnected by means of hinges according to the invention.

In Fig. 1, a profile rail 10 made of z. B. Aluminum profile can be seen, which is shown again in Fig. 2 in a cross-sectional view and which has the wesent union rectangular profile, with double-sided longitudinal grooves 12 , which are usually provided to save material in example. Such rails, which are usually made of aluminum, serve, for example, to build partitions 11 or machine panels, see Fig. 9, wherein the rails 10 form the borders of such walls 11 , but at least their side edges. It has proven to be advantageous to articulate such partition walls at their side edges in order to achieve greater flexibility and adaptability to the machines to be surrounded, but also to allow the various partition walls to support one another. Fig. 9 shows a perspective view of two such movable walls 11 which are each provided at its one longitudinal edge with profile rails 10, the rails 10 are connected via two of the present invention formed Anschraubscharniere 14 to each other pivotable.

Fig. 2 shows an approximately scale view of a cross-sectional view of such a hinge 14 according to a first embodiment, consisting of two hinge flaps 18 , 20 which are articulated via a hinge pin 16 and each carry at least one grub screw, or alternatively, as shown here, a break through 22 for receiving a fastening screw 24 , which in turn is passed through a bore 26 in the fastening rail 10 , see also FIG. 1, to, for example by screwing a nut 28 onto the free end of the fastening bolt 24 , the to connect a side surface 30 of the profile rail 10 to a support surface 32 of the hinge flap 18 (or 20) by clamping.

The bore 26 is expediently arranged so that it lies centrally to the longitudinal groove 12 , so that the nut 28 can be accommodated in this longitudinal groove if necessary. Of course, larger nuts are also conceivable, which are supported on the side surface 30 opposite the side surface 31 of the profile rail. Furthermore, it is also conceivable to provide the bore 26 with an internal thread into which a screw bolt 24 can be screwed.

The screw-on hinge 14 shown in FIG. 2 can be seen again in a similar representation in FIG. 4A, while FIG. 4B shows a view from below of this hinge (seen according to FIG. 4A), while FIG. 4C shows a view from 4A is the top of the hinge of FIG..

Can be seen in particular FIGS. 4B and 4C that the opening 22 in the tab 18 (respectively corresponding to the tabs 20) has the form of a slot, wherein only one of the like breakthrough per hinge leaf is present.

Accordingly, only one opening 26 will be required for the associated profile rail for this tab.

In order to prevent rotation of the flap 18 or 20 with respect to the profile rail 10 around the bore 22 , the pin or block 36 shown in FIGS . 3A, 3B and 3C is used in different views, consisting of a foot 38 and one Head 40 exists and can be seen in FIGS. 3A to 3C in an approximately double enlarged representation. This pin or block can be used with its foot, which has a cross profile 42 , in correspondingly shaped depressions 44 of the hinge flap 18 or 20 , so that the pin then with its head 40 , see also FIG. 2, over the contact surface 32 of the Hinge tab 18 or 20 protrudes and is accordingly able to engage in the groove 12 of the associated profile rail 10 and thereby fix the hinge tab at a second location (next to the first location, formed by the fastening bolt 24 ) and thus a rotation about the bolt 24 to prevent.

In order to achieve additional security when arranging an elongated hole instead of a round hole, as shown in FIG. 6, it is expedient if two such pins or blocks are arranged in corresponding depressions 44 , which are preferably symmetrical to the central axis 46 of the hinge flap 18 or 20 lie and thereby, irrespective of the presence of the fastening bolt 24 , cause a rotation lock by penetrating and being guided within the groove 12 .

As is apparent from FIGS. 3A to 3C, the head 40 has the pin or stud rectangular shape with a longer side of the rectangle 48 and a shorter side of the rectangle 50, with the actual dimensions can be, for example 10 or 8 mm, as shown in Fig. 3C specified. Due to these different dimensions, the. Head adaptable to two different groove widths 52 of the profile rail 10 , in which either the head with its longer rectangle side 48 is arranged transversely to the longitudinal axis 54 of the profile rail 10 , or with its shorter rectangle side 50 , as is also shown in FIG. 1.

The axial extent 56 or height of the head is preferably adapted to the depth of the groove 12 and can be, for example, 2 mm, in adaptation to conventional rails.

The foot 38 of the pin 36 , which is shown in Fig. 3A, consists of two perpendicular corners arranged, the longitudinal extent 58 of the two rectangles is larger than the transverse extent 60 , so that the recognizable cross profile shape results with inward jumping corner areas 62 , the dimensions of which result from half the difference between the longitudinal and transverse dimensions and are referred to as the grid dimension. This means that this grid dimension is half the difference between the longitudinal extension and the transverse extension. In the embodiment shown, the longitudinal extent of the foot profile is a little less than 5 mm, the transverse extent a little less than 3 mm, so that the difference is a little less than 2 mm, so that the grid dimension here is a little less than 1 mm. This means that the longitudinal extent makes up about five grid dimensions, the transverse extent measures about three grids.

The axial extent of the foot 38 , which can be seen in FIG. 3B, preferably corresponds approximately to the size of the transverse extent 60 , in this case approximately three grid dimensions or also approximately 3 mm.

In order to be able to introduce this foot into the corresponding depression 44 without great problems, it makes sense to design these depressions to be slightly larger, that is to say, for example in accordance with the illustration in FIG. 5D, to construct them from intersecting rectangles which have a longitudinal extension 158 of approximately 5 mm, have a transverse extension 160 of approximately 3 mm, that is to say slightly larger than the corresponding dimensions for the foot. Here, the grid dimension 162 is approximately 1 mm.

Of course, other absolute dimensions are also conceivable, but the grid dimension of 1 mm was chosen because this results in a grid distance that is often desired. This grid distance is formed by the grid dimension insofar as, see for example Fig. 6, several such cuts 44 mutually overlapping obliquely in the corner of the rag can be arranged such that grid-like increasing distances between one used in a respective depression Pin or block and the, hinge axis 64 result. These depressions close z. B. to each other so that they have a different distance of just 1 mm to the axis 64 , see the depressions "20" and "19" in Fig. 4D. In contrast, the subsequent depression (see here the number "18.5" within this depression) is such that only a 0.5 mm reduction in distance from the axis 64 is achieved. The subsequent depression "17.5" is again offset by a full mm millimeter, as is the last depression "16.5".

Due to the cross shape of the foot of the pin or block it is possible, despite the overlapping depressions, to anchor this foot non-rotatably in one of the five depressions shown in FIG. 4D, because this foot always succeeds within two opposite corners, see the reference numbers 66 , 68 in Fig. 4D with corresponding foot edges 166 , 168 (see Fig. 3C) to secure against rotation.

In this way, it is possible to use the foot in the five different depressions 44 , each of which is formed on both sides of the elongated hole 22 on each tab 18 and 20 , respectively, and to achieve a different distance for the front head from the hinge axis 64 , The double distance to the axis 64 is indicated in FIG. 4D in each case and is, for example, 33 mm, 35 mm, 37 mm, 38 mm and 40 mm. This can be clearly seen that the distances each increase by 2 mm, except for the one step at which only a distance increase of 1 mm (0.5 mm calculated on the half hinge) is brought about. This is the difference between the two depressions which have the inscribed numbers "19" and "18.5" in FIG. 4D.

By appropriate different choice of use for the flap 18 and the flap 20 can thus be realized under different total distances, while the distances shown in FIGS . 4, 5, 6 and 7 are only applicable with a symmetrical arrangement. Thus, a distance of 20 mm for the flap 18 can be combined with a distance of 19 mm for the flap 20 , which results in a total distance of 39 mm. For this purpose, one would have to insert the pin on the rag 18 in the depression with the number "20", on the rag 20, however, in the depression with the number "19".

By using the depressions "16.5" in conjunction with, for example, "19", a grid dimension 35 , 5 can also be realized, correspondingly grid dimensions 36 , 5 , 37 , 5 , 38 , 5 are possible by a corresponding combination of the existing depressions.

To adapt to these different distances, the opening 22 has an elongated elongated hole shape, so that a fastening bolt inserted through this elongated hole can follow the displacements.

In order to enable a secure attachment using a head screw, a corresponding depression area 96 (inclined surface) or 196 (circumferential shoulder) is provided, on which a corresponding head of a mounting screw can rest without the displaceability along the elongated hole would be disabled.

In FIGS. 5A to 5D, a similar construction as can be seen in FIGS. 4A to 4D, except that the flock nierlappen 118, 120 elongated holes 122 have a greater length, so that a greater variability is given here.

In order to nevertheless obtain a narrow grid dimension again, another form of attachment of the depressions has proven to be expedient, see in particular FIG. 5D. As can be seen, three depressions "21.5", "26", "31" are initially provided, these digits each indicating the distance to the axis 64 in mm, the depressions "26" and "31 "touch directly, but do not overlap, while the depressions" 21.5 "and" 26 "overlap slightly. These three indentations lie on a line 70 parallel to the outer edge 68 , in contrast to the embodiment according to FIGS . 4A to 4D, where the indentation points were each arranged on an oblique line, directed into the hinge tab corner.

In the embodiment according to FIGS. 5A to 5D, two further depressions are arranged on a line 72 , two further distances “21” and “27.5” being realized here. To do this, the line "22.5" is offset on line 74 , and the line "23.5" is located on yet another line 76 .

With a symmetrical arrangement of pins or blocks 36 in corresponding depressions, the distances indicated in FIG. 5B between these blocks and thus between rails connected by the hinge result, namely 42, 43, 45, 47, 52, 55 and 62 mm. But here, too, intermediate values can be achieved by different selection of depressions on the flap 118 or 120 , similar to what has already been described with regard to the embodiment according to FIGS. 4A to 4D. So you could combine "21" with "21.5" and reach the distance of 42.5. The combination of "22.5" with "21.5" results in a distance of 44 mm.

The arrangement shown thus allows at least in the smaller distances very fine gradations of Ent distance, while the larger distances are coarser Gradations can be realized.

However, it is not only possible to combine flaps of the same size with one another, for example flaps 18 , 20 according to FIG. 6, or flaps 118 , 120 according to FIG. 7, but also a longer flap 120 with a shorter flap 18 can be combined, as can be seen in FIG. 8. This again results in different removal options, which are between 37.5 and 51 mm here, partly in steps of 0.5 mm, partly in steps of 1 mm, sometimes in even larger steps.

If such a fine-tuned variability is not necessary can be worked with fewer depressions, for example in the form that each depression for itself is arranged and with no other depression overlaps. As a result, the foot anchoring of the pins or the blocks even stronger and they tolerate even bigger ones Leverage.
