[0030] FIG. 10 shows the fastening of the metal base on the jacket tube in exploded representation.

[0031] In the drawing, the jacket tube of a hole-in-the-ground beverage cooler according to the invention, inserted into a hole in the ground and manufactured from a suitable plastic, is denoted by the reference symbol 1. A carrying device 2, which is equipped with several disk-shaped beverage holders 3 disposed at axial distance from one another and carried by a carrying bar 4 that can be extended upward out of the jacket tube 1, can be inserted from above into the interior space of this jacket tube 1. The jacket tube 1 is screwed at its lower end together with a tightly sealing metal base 5 (see FIG. 10) and can be closed at its upper end by means of a removable cover 6 (see FIGS. 1a, 1b and 1c) when the carrying device 2 is inserted.

[0032] The beverage holders 3 illustrated in detail in FIGS. 2-5 are respectively equipped with several hanger openings 7a, 7b, 7c and 7d, which are disposed in distributed manner on their circumference, are accessible from the periphery and are respectively used for hanging of the bottle necks of beverage containers 8 (for example, beer bottles or champagne bottles 8a). Above these hanger openings 7a, 7b, 7c and 7d, the beverage holders 3 are further equipped with cylindrically curved bracing walls 9a, 9b, 9c and 9d, which are open toward the periphery of the beverage holder 3 for bracing any desired beverage containers 8 (e.g. 8b or 8c) of different diameters, which containers are respectively inserted from above into the beverage holder 3. These bracing walls 9a, 9b, 9c and 9d respectively have a radius of curvature increasing stepwise with increasing axial distance from the hanger openings 7a, 7b, 7c and 7d and are accordingly well adapted to beverage containers 8 of different diameters.

[0033] For fastening on the beverage holder 3 on the carrying bar 4, the beverage holders 3 are respectively provided centrally with a passage opening 10 for the carrying bar 4. Furthermore, clamping springs 11, which can be clamped securely at any desired height position on the outer circumference of the carrying bar 4 and fix the beverage holder 3 disposed above it, serve for fixation of the beverage holder 3 on the carrying bar 4.

[0034] For this purpose, the clamping springs 11 are designed as leg springs having several spring coils 11a bearing axially against one another and surrounding the carrying bar 4, and their inside diameter is smaller than the outside diameter of the carrying bar 4 when the clamping spring 11 is relaxed, wherein the upper spring leg 11b of this clamping spring 11 is braced in twist-proof manner on the underside of the beverage holder 3 and the lower spring leg 11c of this clamping spring 11 is designed as a handle, which serves to transmit a torque that tensions the clamping spring 11.

[0035] For fixation of the upper spring leg 11b of the clamping spring 11 on the underside of the beverage container 3, receiving openings 12 for the accommodation and fixation of this spring leg to 11b are provided respectively on the underside of the beverage holder 3, wherein these receiving openings 12 respectively have at least one undercut 13, in which the upper spring leg 11b of the clamping spring 11 can be elastically latched (see FIGS. 8 and 9).

[0036] For displacement and fixation of a beverage container 3 at the respectively desired height position on the carrying bar 4, it is sufficient with one hand to hold the beverage holder 3 securely and with the other hand to transmit, to the clamping spring 11, by means of the lower spring leg 11c of the clamping spring 11, which is designed as a handle, a torque that tensions the clamping spring 11. Hereby the threads 11a of the clamping spring 11 bearing on the outer circumference of the carrying bar 4 are raised away from the outer circumference of the carrying bar 4, so that the clamping spring 11 can be moved directly in axial direction of the carrying bar 4. For fixation in the changed position, it is sufficient to release the lower spring leg 11c of the clamping spring 11, which is designed as a handle, whereby the threads 11a of the clamping spring 11 are again secured with high contact force on the outer circumference of the carrying bar 4, so that the beverage container 3 braced on the clamping spring 11 becomes fixed in the new position.

[0037] For lifting of the entire carrying device 2 together with the beverage holders 3 fastened on it, its carrying bar 4 is equipped at the upper end with a handle (see FIG. 1a).

[0038] In order to facilitate and at least partly automate the process of extraction of the support device 2, its carrying bar 4 is connected to the cover 6 of the jacket tube 1 and equipped with a pneumatic spring 15, which is braced on the base 5 of the jacket tube 1 (see FIG. 1b). During actuation of this pneumatic spring 15, a movable overall unit, consisting of the carrying bar 4, the beverage holders 3 loaded with beverage containers 8 and the cover 6, is lifted out of the jacket tube 1 buried in the ground in such a way that all of the beverages held in stock in the beverage cooler become accessible for consumption.

[0039] For initiation and termination of these movement processes, the pneumatic spring is equipped with a depressible switching element 16, whichin the manner of a ballpoint pen mechanismalternately and successively locks and releases the pneumatic spring 15.

[0040] An alternative to the semi-automatically assisted movement of the carrying device 2 explained above provides that the complete carrying device 2 is extracted and inserted with the aid of an electromotive rotary spindle drive 17 braced on the base 5 of the jacket tube 1 (see FIG. 1c). Moreover, during the use of such a rotary spindle drive 17, the carrying device 2 is guided in a twist-proof manner on the wall of the jacket tube 1 by corresponding guide rails 19.
