Description

Shelf stand pipe for height-adjustable shelves _t

The innovation relates to Reg.al standpipes for height-adjustable shelves: to set up shelves with any storage compartments for warehouses, shops and the like

So far, shelf standpipes are known on which the shelves via fasteners such. B. screws or Hanging brackets, which engage in threads or bores on the pipe rod. This type of attachment has the disadvantage that a height adjustment of the shelves can only be carried out in stages. On other known shelf standpipes, the ad positions are loaded using clamps or sleeves.

that are pushed over the upright tube and are clamped to this with the help of screws or the like . With this type of fastening, the shelf height can be adjusted steplessly, but the clamps or sleeves are difficult to fasten and also form annoying protrusions and corners.

The task of the innovation is to create a shelf upright tube to which shelves can be attached continuously adjustable in height and which has no protrusions or outwardly protruding edges.

The task is solved by a shelf upright tube that has a longitudinal slot for receiving screw heads as well as one in the interior of the tube spanning the slot approximately at the distance of the screw head height and integral with the tube Has bridge.

With a shelf upright tube designed in this way, a shelf can be placed in any desired by moving the screws Height can easily be set by screwing on a nut. There are no protrusions or outwardly protruding edges. Will be at this Shelf standpipe in a further development, the width of the slot chosen so that it has the square shaft of a standard tube can lead, then there is no need to hold onto the

W would take the usual truss-head bolts with square shank (DlN

It can also be advantageous to turn the edges of the slot inward to form a to reinforce the flat contact surface for the screw head.

The standpipe is preferably shaped as a round tube because there are naturally no disturbing edges. For example, however, as part of the innovation, it is possible to make the pipe square, with one corner of the square being shaped into a slot over which a bridge is attached parallel to the corresponding diagonal of the square to accommodate a countersunk screw.

For shelves that need to be kept particularly clean, for example For storing food and the like., It is advantageous to open the slot between the screws by means of a Undercut of the slot engaging, resiliently fitted

Profile made of rubber or plastic to close flush. This creates a possibility of preventing contamination eliminated and cleaning made easier.

The innovation is explained in more detail below using an exemplary embodiment with reference to the drawing.

Fig. 1 shows an embodiment of the shelf standpipe according to the innovation in a cross-section at the level of a shelf fastening screw.

Fig. 2 shows the same shelf stand pipe in a partial section at the level of a closure profile represent.

In Fig. 1, a round shelf stand pipe 1 with a longitudinal slot 2 and one with the jÄegal stand pipe is in one piece formed, the longitudinal slot spanning bridge 3 provided. In the one from the longitudinal slot 2 and the bridge 3 formed undercut mushroom-shaped opening sits a Normgeroäß truss head screw 4. Bin square shank 5 of the

"Truss-head screw 4 is guided by the longitudinal slot 2 and

secured against twisting. A flat, round screw head 6 rests on a flat support surface 7, which is reinforced by reinforcement of the longitudinal slot edges towards the inside of the pipe:. On the screw 4 is a nut 8 by means of a

Shelf 9 consolidated. Between the mother 8 and the ab- | position 9 is a washer 10, for example a '( spring washer inserted. The Ali position 9 is at its edges ^

bevelled to increase its stiffness and at its corner to the s Shelf standpipe 1 adapted in a form-fitting manner. The washer I washer or spring washer 10 is used to secure animal mother;

8 against twisting. §

In Fig. 2, the longitudinal slot 2 with a closure | profile 11 closed. The closure profile 11 consists of J resilient material, for example made of rubber or corresponding |

ϊ the plastic and has an essentially U-shaped | Cross-section, the free ends of the U-legs with ü

Projections 12 are provided which engage the undercut support surface 7. The outer edges of the
Longitudinal slot 2 are chamfered and take the outward
towards the widened outer part of the locking profile 11,
so that this does not continue in the cavity from the longitudinal slot
2 and bridge 3 can penetrate and its outer surface with
the shelf stand pipe 1 is flush.

In the illustrated shelf stand pipe 1 can through
simply loosening the nut 8 the support 9 together with

By its spring action it is with the help of the Projections 12 held in place · Its outer surface completely closes off the slot and forms the shelf support tube 1 a smooth surface «that is easy to clean. Through this any3 inaccessible corner windows are avoided.
