CZ2001812A3 - Circular section column shelf stand - Google Patents

Abstract

Shelf support comprises a column (30) formed from a round tube and a crossbeam (31) formed from a round tube and running perpendicularly to the column. The column is connected to the crossbeam by two bolts (36) whose upper parts are connected to the inner wall of the column at two diametrically opposite positions and pass through two holes (37) in the middle of the crossbeam.

Description

Shelf stand with round post

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a shelf stand with a round column in the form of a pipe and a beam extending to this round column, also comprising a pipe.

BACKGROUND OF THE INVENTION

There are known racks for metal racks, especially exhibition and sales racks, whose columns and heel brackets are made of round hollow profile elements. Round, especially round hollow profiles are particularly advantageous for their high stability at low material costs. The posts are usually provided with slots for hanging brackets or other racking elements, and the foot booms are provided with plate or other foot bases.

In freestanding rack stands, the boom brackets are often welded to the post. However, in the case of round posts, welding entails increased labor costs.

A further disadvantage of rigidly welding the column to the heel is that the result is rack racks that are L- or T-shaped as a whole, and which are therefore bulky, which is a disadvantage in transportation, packaging and handling.

WO 96/10936 discloses a construction in which a column made of a round profile with a U-shaped molding attached thereto is anchored to a three-spoke round section. There is nothing else mentioned about anchoring except welding.

• · · · · · ·

DE-A-4 417 339 relates to the attachment of a round post to a square pedestal in which a special support cone is formed. The round post is attached to this support cone exclusively by force, in particular by means of a conical clamping sleeve, which is screwed to the support cone of the boom by means of three pins, clamping the lower end of the post. This type of connection assumes a special profile for the boom and relatively tailored attachments and is unsuitable for higher loads.

The object of the invention in general is therefore to at least partially eliminate the drawbacks of the known rack racks. It is a further object of the invention to provide a base member construction for easy-to-produce rack racks, in particular round column rack racks, which will also be easy to handle.

SUMMARY OF THE INVENTION

This object is solved and the drawbacks of the known solutions of this kind are largely eliminated by the shelf stand with a round column in the form of a pipe and a beam which extends to this round column, also consisting of a tube according to the invention. a pair of pins, the upper parts of which are mutually opposite sides connected to the inner wall of the round post and pass through two holes formed in the vertical median plane of the boom.

The round post-boom connection made in this way allows the racking to be assembled in just a few operations at the rack mounting location. The pins of the invention provide high strength of this joint, which can withstand high loads.

The lower end of the round post is preferably cut in the cutting 4444 4444 4444 4444 4444 4444 4444 4444 4444 4444 4444 4444 4444 4444 4444 4444 4444 a cylindrical shell surface corresponding to the outer boom profile.

Preferably, the pins extend substantially over the entire height of the boom and are attached at their lower ends to the boom.

It is preferred that the bolts are fastened to the boom by bolts that extend through the lower side of the boom through additional holes and engage internal threads at the lower ends of the bolts.

The upper portions of the pins are preferably welded to the inner wall of the round post.

The described measures bring an increase in the strength of the connection of the round post with the bracket and also its resistance to refutation.

Furthermore, it is advantageous if the bracket is provided in the area between the pins with a threaded sleeve for receiving the disc foot. The plate foot can thus be arranged exactly in the axis of the round column.

DETAILED DESCRIPTION OF THE INVENTION

The shelf stand shown in FIG. 1 consists of a round post 30 and a boom 31, both of which are made of hollow sections of circular cross-section. It is preferred that the round post 30 and the boom 31 have identical cross sections. The round post 30 is provided with rows of double cut-outs 32 for suspending hooks of racking brackets, rear walls or other racking elements along its entire height, along four axially extending lines 90 ° to each other.

The boom 31 is closed at both ends by locking elements 33. Near these locking elements 33, disc heels 34 with an adjustable height are arranged on the underside of the boom 31.

Referring to FIG. 2, the round post 30 is cut at its lower end into a cylindrical surface to form a cutting surface 35 having a radius corresponding to the outer radius of the boom tube.

31.

As can be seen from FIG. 3, cylindrical pins 36 are provided on two axially extending sides of the boom 31 opposite to each other of the round column 30, which are at their upper ends.

The two studs extend from the lower end of the round post 30 to a distance that corresponds to the diameter of the boom 31.

The two pins 36 extend through two holes 37, which are formed at the highest point of its periphery in the vertical median plane of the boom. The pins 36 extend substantially over the entire cross-sectional height of the boom 31 so that they terminate at the lowest point of the boom periphery 31. At this point, two additional holes 38 are formed in the boom 31 and are aligned vertically with the holes 37. Through these additional holes 38 they pass through bolts 39 which engage the female threads 40 in the lower portions of the pins 36.

The holes 37 are only slightly larger in diameter than the pins 36 and the other holes 38 are similarly only slightly larger in diameter than the screw shafts

39. Further, the pins 36 terminate just above the inside of the boom 31 to achieve tightening when the screws 39 are tightened. All these measures, in conjunction with the cylindrical cutting surface 35 of the round post 30, result in a rigid and non-refractory connection of the round post 30 to the boom 31.

While the shelf stand of FIG. 1 is a two-sided shelf stand, FIG. 4 shows a boom 31 ¹ for a one-sided shelf stand. In this case, the holes a 38 for the studs not shown here 36 of the round pillar 30, not shown here, are formed near the right end of the boom 31 '. Between the other holes 38 in the underside of the boom 31 * is provided a threaded sleeve 41 for receiving a height-adjustable plate foot 42. The sleeve is provided with a threaded sleeve. Since the pins 36 are arranged on mutually opposite sides of the inner wall of the round post 30, a space between the other holes 38 is sufficient to accommodate said plate foot 42, which is thus located on the axis of the round post

30.

A similar plate foot 42 can be used with the double-sided shelf stand of Figure 1, where it then serves as the central plate foot disposed between the outer plate feet 34.
