Abstract:
In a display stand comprising a pedestal, a carrier column and a goods carrier secured to the carrier column, it is proposed that the goods carrier is fixed to the carrier column in that a wedge engagement sleeve engages from beneath in a wedge engagement tube of the goods carrier.

Description:
BACKGROUND TO THE INVENTION 
     The invention relates to a display stand comprising a pedestal, a carrier column supported by the pedestal, and at least one goods carrier secured on the carrier column. 
     STATEMENT OF THE INVENTION 
     Such display stands are used especially for the display of special ranges of goods in sales premises, such as department stores. With regard to the storage of the display stands by the users and their transport to the users, pedestal, carrier column and goods carrier are made separable from one another, so that they can be accommodated in minimum space. It is therefore of essential importance that the individual parts, namely pedestal, carrier column and goods carrier, can be connected with one another in a stable manner, so that even when loaded they hold together without danger of disengagement from one another and do not assume any askew position in relation to one another. 
     OBJECT OF THE INVENTION 
     An object of the invention is to provide a durable connection especially between the carrier column and the goods carrier, guaranteeing an unambiguous orientation of the goods carrier in relation to the carrier column. 
     SUMMARY OF THE INVENTION 
     To solve this problem it is proposed in accordance with the invention that the goods carrier is seated with a downwardly open wedge engagement tube on an upwardly converging wedge engagement sleeve which surrounds the carrier column in clamping manner. 
     In the form of embodiment according to the invention the retention and orientation of the goods carrier in relation to the carrier column become the better, the greater is the loading of the goods carrier, because the wedge engagement tube and the wedge engagement sleeve are pushed still more into one another by the loading and the wedge engagement sleeve is applied more strongly to the carrier column. 
     In principle it is conceivable for the vertical fixing of the wedge engagement sleeve on the carrier column to be effected exclusively by the clamping of the wedge engagement sleeve with the carrier column. However with regard to increased security against axial displacement it will be preferable to support the wedge engagement sleeve downwards by a support element which can be made fast on the carrier column. In principle this support element can be integrated into the wedge engagement sleeve, but according to a preferred form of embodiment it is a separate component. This support element can be formed by a ring grasping around the carrier column and a screw penetrating this ring. 
     The wedge engagement sleeve is expediently slotted so that with little application of force it can be narrowed and thus clamped fast upon the carrier column. 
     Beside round goods carriers, non-circular goods carriers are frequently used. These must be fixed in their angular position in relation to one another and in relation to the pedestal. This can take place in a manner in which the carrier column possesses at least one profile section departing from the circular cross-sectional form and the goods carrier correspondingly has a matching profile section. This profile section is preferably formed so that it is optically as inconspicuous as possible; this is most easily achieved by a flat facet extending for example over a center angle of 60° to 90°. Since the wedge engagement sleeve is preferably slotted in any case, it is possible to bring a rotation-preventing projection of the goods carrier in each case through the slot of the wedge engagement sleeve into engagement with a groove or flat facet of the carrier column. 
     It is also conceivable merely to provide a marking extending along a generatrix on the carrier column, and counter-markings on the goods carriers which are adjusted to the marking line in assembly. 
     The pedestal can be assembled from at least two storied pedestal pieces, namely a base pedestal and an upper pedestal, and at least one of the storied pedestal pieces can be formed for use without the other. In this way it is possible to obtain various forms of storied pedestal pieces with moderate tool expenditure for the production. 
     A pedestal or base pedestal can be formed with a carrier column reception pit which possesses a fixing projection at its bottom for engagement in the lower open end of the carrier column and is covered at its top by a centering washer which has a centering opening closely surrounding the carrier column and is fixed to the pedestal. In this way the carrier column can be held fast exactly vertically and immovably in the pedestal. The centering washer can here be connected with the pedestal at the upper end of the carrier column reception pit in bayonet catch manner. 
     The carrier column can be assemblable from individual carrier column sections. In this way the transport and storage problems are further simplified.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The pedestal 10 consists according to FIG. 2 of a base pedestal part 10a and a top pedestal part 10b. The two parts, base pedestal part 10a and top pedestal part 10b adjoin one another in such a way that the junction is noticeable only as a narrow line, which can also be interpreted as a decorative line, or not at all. The base pedestal part 10a comprises a base portion 10b, a sleeve portion 10i tapering upwardly from the base portion 10b, and an upper transversal wall 10k. The transversal wall 10k has a downwardly tapering carrier column reception pit 10c with a bottom wall 10l and an upwardly directed fixing projection 10d which corresponds to the internal cross-section of the carrier column 12. The top pedestal part has an upwardly extending sleeve portion 10n and an upper terminal wall 10o. The sleeve portion 10n forms a smooth upwardly tapering continuation of the sleeve portion 10i of the base pedestal part 10a. The sleeve portion 10n has a lower edge portion 10a received by an inwardly recessed fixation step 10p located adjacent the upper end of the sleeve portion 10i. If the carrier column is non-circular as represented in FIG. 2, on the upper side of the base pedestal part 10a an orientation mark 16 is provided which indicates to the user in assembly in which angular orientation the carrier column must be introduced into the carrier column reception pit 10c in order to be fitted on to the fixing projection 10d. At the upper end of the carrier column reception pit 10c there is provided a centering washer 10e which is fitted by a bayonet catch means 10r on the upper end of the carrier column reception pit 10c and closely surrounds the carrier column 12. The centering washer 10e has a central opening 10m arranged to receive the outer cross-sectional shape of the carrier column. 
     According to FIG. 4 a goods carrier 14 comprises a wedge engagement tube 14a which receives a wedge engagement sleeve 14b. As may be seen from FIG. 6, the wedge engagement sleeve 14b is slotted and encloses the carrier column 12, on which it rests through ribs 14c. After the wedge engagement sleeve 14b has been pushed into the wedge engagement tube 14a the goods carrier is firmly seated non-shiftably on the carrier column 12. In addition for protection against displacement a support element 18 can be provided which is formed by a ring 18a surrounding the carrier column and a clamp screw 18b. A projection 14d of the goods carrier 14 securing against rotation engages through a slot 14e of the wedge engagement sleeve 14b with a flat facet 12a of the carrier column 12. Thus the angle position of the goods carrier 14 in relation to the carrier column 12 is unambiguously fixed. 
     According to the alternative form of embodiment in FIGS. 8 and 9 a line 12&#39;b is scored on the carrier column 12&#39;. A marking arrow 14&#39;f is provided on the goods carrier 14&#39; and is directed with its point to the marking line 12&#39;b, so that in this way a simple angle adjustment of the goods carrier is also possible. 
     FIG. 10 shows how successive sections of the carrier column are fitted together telescopically. 
     FIGS. 11 to 17 show display stands according to the invention with various goods carriers, the goods carriers being adjusted in angle in each case in relation to one another and to the pedestal.
