Description

(1) The invention will be explained in more detail with reference to embodiments shown schematically in the drawing. Therein,

(2) FIG. 1 shows a perspective view of an embodiment of the mounting aid according to the invention in a mounting position,

(3) FIG. 2 shows a perspective view of the embodiment shown in FIG. 1 in the storage position,

(4) FIG. 3 shows a perspective detail view of a first embodiment of the angled fastening element,

(5) FIG. 4 is a top view of the first embodiment of the angled fastening element shown in FIG. 3,

(6) FIG. 5 is a detailed perspective view of a second embodiment of the angled fastening element, and

(7) FIG. 6 is a top view of the second embodiment of the angled fastening element shown in FIG. 5.

(8) In FIG. 1, a mounting aid is designated with 1. The mounting aid 1 comprises two relatively pivotable legs 2, which are connected directly to each other by a hinge 3 exhibiting by a pivot axis A. At their free ends the legs 2 comprise a fastening element 4 that is angled relative to the leg 2, wherein the legs 2 are fixed to sheet metal angles 5 of the frame, said sheet metal angles 5 being directed to each other, projecting inwardly and being provided with a row of holes.

(9) FIG. 1 shows the mounting aid 1 in the mounting position being folded apart about the pivot axis A of the hinge 3 to assume a V-shape. In this position, the upper edge 6 of the legs 2 forms a bearing surface for a rack mount to be installed (not shown in FIG. 1). Furthermore, the legs 2 have longitudinally extending reinforcing ribs 7 in order to increase the flexural rigidity of the legs 2.

(10) For fastening the mounting aid 1 to the sheet metal angles 5 of the frame, the sheet metal angles 5 are each received in an outwardly open gap 8 of the fastening elements 4.

(11) As can be seen from FIG. 1, the sheet metal angle 5 of the frame is provided with a row of holes.

(12) In the state not fastened to the sheet metal angles 5 of the frame, the mounting aid 1 can be folded or unfolded about the pivot axis A in accordance with arrow 9.

(13) FIG. 2 shows a perspective view of the mounting element 1 shown in FIG. 1 in the folded storage position. The legs 2 are abutting flat against each other and are not folded apart. Only the angled fastening element 4 at the end of the legs 2 are protruding.

(14) In FIG. 3 it is shown that the gap 8 formed in the fastening element 4 is formed by two parallel plates 10, 11. The plates 10, 11 are held at an adjustable distance B from each other and are capable of being clamped together or adjusted with the aid of a clamping means 12 under clamping of the sheet metal angle 5 not shown in FIG. 3.

(15) The fastening element 4 engages the sheet metal angle 5 of the frame, wherein the gap 8 receives the sheet metal angle 5. In order to fix the mounting element 1 in the correct position, the gap 8 is placed so as to enclose the sheet metal angle 5, such that the holes located in the plates 10, 11 each cover the holes located in the perforated row of the sheet metal angle 5. In order to reduce the distance between the plates 10, 11 and thereby clamp the sheet metal angle 5 between the plates 10, 11, the clamping means 12 is inserted through the hole 13 of the plate 11 and then screwed into a threaded hole 13 formed on the first plate 10 (FIG. 4).

(16) FIG. 4 shows a top view of the first embodiment of the angled fastening element 4 illustrated in FIG. 3.

(17) FIG. 5 shows a second embodiment of the angled fastening element 4. The first plate 14 delimiting the gap 8 is rigidly connected to the leg 2 and comprises four bolts 16 and 19. Two bolts 16 are guided in longitudinal holes 17 of the second plate 15 so that the second plate 15 is slidably guided relative to the first plate. The bolts 16 have thickened ends 18, which define the maximum distance between the two plates 14, 15 and the thickness of the gap 8, respectively. Two further bolts 19 also have thickened ends 18, which, in the displacement position of the second plate 15 shown in FIG. 5, engage edges of open slots 20 from behind. In order to fix the fastening element 4 to a sheet metal angle 5, the bolts 18 having been exposed by pushing away the second plate 15 are inserted through corresponding holes of the sheet metal angle 5, so that the thickened ends 18 of the bolts 19 project on the other side of the sheet metal angle 5. Thereafter, the second plate 15 is displaced relative to the first plate 14 until the slots 20 open towards the edge engage around the bolts 19, wherein the thickened ends 18 of the bolts 19 engage behind the edge of the respective slot 20, whereby the bolts 19 are secured against falling out of the holes of the sheet metal angles 5 and the fastening element 4 is fixed to the sheet metal angle 5.

(18) FIG. 6 shows a top view of the second embodiment of the angled fastening element 4 shown in FIG. 5.
