FIGS. 7 to 10 show the fixing of the railing struts 4 in the rear end area on the vertical supports already mentioned 6.

It is clear that the railing struts 4 in the rear end region are provided with a mounting head 14, which advantageously opposite the respective rail strut 4 via a Threaded section 15 is screwed.

In this regard, FIG. 7 shows a construction in which the railing strut 4 in the relevant end area with a complete Internal thread is provided, while Figure 9 shows that the rail strut 4 also by two embossed beads 16, the parts form a thread, screwing or unscrewing the fastening head 14 can enable.

Due to the possibility of the rail strut 4 opposite the fastening head 14 to be able to turn via the threaded area 15, a length adjustment of the railing struts 4 and, if appropriate Design of the front panel suspension, also one Adjustment of the front panel 5 enables.

The mounting head 14, according to the embodiments Figures 7 to 10 is identical, bayonet type placed on the respective vertical support 6 and opposite this attached.

The support 6 is, as is clearly shown in FIGS. 7 and 8 attached to a support member 17, which at the same time for support the already mentioned insert 7 of the furniture pull-out part 1 serves. The vertical supports 6 can be fixed or detachable with be connected to this supporting part 17.

As particularly shown in FIGS. 9 and 10, the provide the respective fastening head 14 with a stepped bore 18, with an inwardly projecting in the larger diameter range Nose 19 is provided. The head 20 of each support 6 is provided with sector-like free cuts 21 in order to certain section on the attachment of the mounting head 14 to enable the head 20 of the respective support 6. By subsequent Twist around the longitudinal axis of the respective support 6 engages behind the nose 19 of the fastening head 14 the projecting Areas 22 of the head 20 of the support 6, so that a vertical fixing of the mounting head 14 and thus also the railing strut 4 is rated in relation to the support 6.

The sector-shaped free cuts 21 are chosen so that the rail struts 4 in the solid lines marked in FIG. 2 Position placed on the supports 6 or removed from them can be in the dash-dot position in Figure 2 shown position their vertical fixation relative to the Support 6 but still retained.

FIG. 11 shows a railing strut 4 which, in addition to its horizontally running area a one-piece, has vertical support 6a. Their lower head 20a is in the formed in the same way as the head 20 of the support 6 the exemplary embodiments according to FIG. 9 and FIG. 10.

The supporting part 17a is in the exemplary embodiment according to FIG. 11 analogous to the fastening head 14 with a stepped bore 18 and one in the larger diameter range, towards the inside projecting nose 19 equipped. In other words in the embodiment of Figure 11, the connection between the support 6a and the support member 17a with that in Figures 9 and 10 shown embodiment identical with the difference that the downward-facing support 6a of the railing strut 4 in the fastening area of the support member 17a inserted and twisted is secured vertically.

The support parts 17 and 17a are in the exemplary embodiments 7 and 11 designed as plastic moldings.

Figure 12 shows an embodiment in which a support member 17b is formed as a sheet metal part. The not shown Rail strut is analogous to the embodiment Figure 11 with a downward vertical support 6b made in one piece. This support 6b has at its lowest End a pin 23 whose diameter is smaller than the diameter of the support 6b otherwise. On this pin 23 a radially projecting locking lug 24 is provided through a corresponding recess 25 within a lower one Bore 26 of the support member 17b can be inserted. The hole 26 has the diameter of the pin 23 and an upper one Bore 27 of the support member 17b is in terms of its diameter identical to the diameter of the support 6b.

The radially projecting and largely in terms of shape with the locking lug 24 is identical recess 25 of the lower bore 26 with regard to their radial course with respect to the longitudinal axis a guide rail 28 to which the supporting part 17b is connected is offset by a certain angular amount. This angular amount is again chosen so that the insertion of the above described support 6b in the support member 17b only in the position a railing strut 4 can take place, as can be seen in FIG Solid lines are shown. Now the respective rail strut 4 pivoted to its normal position relative to this position, the railing strut 4 is secured vertically with respect to the supporting part 17b, since the latch 24 now the tab 29 in which is the lower bore 26, engages under.

The connection between the support 6b and the corresponding one Railing strut can only be canceled as far as previously matched the position of the locking lug 24 with the Position of the recess 25 is brought about.

The main advantages of the different embodiment the invention is that convenient setting the railing struts can be brought about in relation to the vertical can that the railing struts 4 if necessary from the useful area the hatchet can be swung out without the to have to abolish vertical definition so that any existing Inserts 7 conveniently removed and after cleaning can also be used again.
