Definitions

• the invention is based on a device for fastening components according to the preamble of claim 1.
• a fastening plate is already known which can be connected to additional fastening plates by means of coupling devices.
• the coupling devices have the shape of a double T and are anchored in mutually opposite T-grooves, which are formed on the long sides of the fastening plates.
• the mounting plates are made using the aluminum extrusion process.
• the warpings caused by the manufacture can lead to gaps forming between the fastening plates arranged in a row.
• the individual mounting plates are not very stiff, which can cause them to bend when the components are attached.
• the T-grooves on the long sides lying opposite one another must be completely filled with coupling elements. Especially when using tion of coupling elements that have a press fit in the T-slots, this leads to a complex assembly, since each individual coupling element must be inserted with the required force into the mounting plates. If the opposite T-slots of the mounting plates are not completely filled with coupling elements and these have a sliding fit, the coupling elements can slip in the T-slots. Since the coupling elements have a relatively large volume, the weight is also correspondingly high.
• EP 0 645 215 B1 provides for the mounting of the mounting plates on support structures using mounting screws and mounting brackets. To do this, the mounting brackets must first be attached to the mounting plates with screws. The legs of the mounting brackets to be attached to the support structure must be aligned so that they all lie in one plane. Then the mounting brackets can be attached to the support structures with additional screws. This type of assembly is relatively complex.
• the device according to the invention with the characterizing features of claim 1 has the advantage over the fact that the device is very rigid and yet easy to assemble.
• the mounting plates can be easily strung together because their front faces are attached directly to connecting elements of any length.
• the surface of the device can be changed as desired, and only a few parts are required for this.
• Another advantage is that the coupling elements in the recesses without effort can be inserted and are still fixed by extensions in the indentations.
• slot nuts have an even lower weight due to the division into sections which have two different widths, without the device losing rigidity.
• bores can be formed in the long sides of the fastening plates or can even be retrofitted. Pins are inserted into these holes. The rigidity of the device can thus also be influenced subsequently.

• a wrench suitable for the hexagon socket 36 can be passed through the transverse bores 26.
• undercut grooves 24 are formed both on the front 19 and on the rear 40 of the clamping plate 12.
• the axis of symmetry 39 of a groove 24 on the rear side 40 lies in the middle between the axes of symmetry 41 of two grooves 24 on the front side 19.
• the mounting plate 12 consists of three fastening plates 42, 44, 46 of the same width and of the same length.
• the fastening plates 42, 44, 46 each have three cavities 48, 50, 52 inside, which are separated from one another by webs 54, 56.
• the webs 54, 56 run from the edge of the groove base 58 of a groove 24 on the front side 19 to the edge of the groove basically 60 of a groove 24 on the rear side 40.
• a screw channel 62 or 64 is integrated in the respective corner formed by the web 54 or 56 and the groove base 58 or 60.
• the screw channels 62 and 64 are open to the cavities 48 and 52.
• the end face of each screw channel 62, 64 is the threaded bolt 38 of a screw 18.
• a further undercut groove 24 is formed on each of the two outer fastening plates 42, 46 on the longitudinal sides facing away from the middle fastening plate 44 and can be used for fastening purposes.
• a long side 66 of the fastening plate 42 faces a long side 68 of the fastening plate 44 and a long side 70 of the fastening plate 44 faces a long side 72 of the fastening plate 46.
• a continuous groove 74 is formed in each longitudinal side 66, 68, 70, 72 in the longitudinal direction of the longitudinal sides 66, 68, 70, 72.
• the individual grooves 74 on the long sides 66, 68, 70, 72 are aligned with one another.
• Sliding blocks 76, 86 are arranged in them.
• FIG. 4 shows the arrangement of a sliding block 76 in two mutually opposite grooves 74.
• the grooves 74 the width of which is greater than the depth, have side walls 75 which taper towards the groove base, and rounded inner edges.
• Each outer edge 78 of the two grooves 74 has an indentation 80 which has the shape of a quarter circle.
• the sliding block 76 has a cross section that corresponds to the shape of two opposite grooves 74. This means that the sliding block 76 Because of the two grooves 74 tapering towards the groove base, it has approximately a hexagonal shape, as can also be seen from FIG.
• FIG. 5 shows that the two extensions 84 extend over the entire length of the sliding block 76.
• the two projections 84 are encompassed by the indentations 80 in the assembled state of the device 10.
• the cross section of the sliding block 84 is constant over its entire length.
• a modified slot nut 86 is shown in FIGS. 7 and 8. It consists of several first sections 88, some of which have the cross section of the sliding block 76, and second sections 90, which connect the first sections 88.
• the extensions 84 also extend over the entire length of the sliding block 86.
• the second sections 90 are approximately twice as long as the first sections 88.
• the second sections 90 are narrower than the first sections 88, such that they do not extend as far into the groove bottom of the grooves 74 as the first sections 88.
• the first sections 88 also have flanks 82 which extend towards the groove bottom of the grooves 74 rejuvenate.
• recesses 92 are formed on the edges of the flanks 82, which would be in contact with the side walls 75 of the grooves 74, which run perpendicular to the groove base of the grooves 74.
• only thin webs 94 which are 0.8 mm to 1 mm wide are left of the flanks 82.
• the area of the sliding blocks 86 which is in contact with the side walls 75 of the grooves 74, is very small. This has following meaning: If the fastening plates 44 and 46 are assembled, a certain force is exerted on them when they are strung together so that they lie flush. This force is in turn transmitted from the side walls 75 of the grooves 74 to the webs 94 of the sliding blocks 86. Since the webs 94 are very thin, they can be plastically deformed in the case of strongly distorted fastening plates 44, 46. This enables a certain tolerance compensation.
• the sliding blocks 76, 86 are arranged in the grooves 74. Due to the shape of the grooves 74, the sliding blocks 76, 86 can be inserted in a simple manner, for example first in the longitudinal side 72 of the fastening plate 46.
• the slot nuts 76, 86 are oriented by the indentations 80 and extensions 84.
• the flank 82 of the sliding blocks 76, 86 are fixed by the side walls 75 of the grooves 74.
• the slot nuts 76, 86 can be positioned in any number, at any point in the groove 74. This enables adaptation to different situations. If the fastening plates 42, 44, 46 are, for example, very thin, strongly warped and have gaps between the individual fastening plates 42, 44, 46, the entire length of the grooves 74 is filled with sliding blocks 76, 86. As a result, no gaps are visible on the one hand, and since the individual fastening plates 42, 44, 46 are mutually supported by the sliding blocks 76, 86, on the other hand the rigidity of the device is increased. Are the mounting plates 42, 44, 46 thicker and less distorted, a sliding block 76, 86 may be sufficient.
• the mounting plates 42, 44, 46 can be manufactured inexpensively and in any length in the aluminum extrusion process.
• the sliding block 76 can be produced in a process similar to the aluminum extrusion process from plastic processing - extrusion. This allows parts of any length to be produced.
• the slot nut 86 is manufactured by injection molding because of the non-constant cross-sectional shape. It can also be designed as an aluminum die-cast part. In this case, the non-constant cross section saves weight.
• grooves 74 it is also possible to form bores with countersinks in the long sides of the fastening plates. Pins are used as coupling elements which have a circumferential collar in the middle.
