Abstract

A dismantleable standing table with a table top plate, a supporting construction on which the table top plate rests, and with a base support. The standing table has three parts, which are screwed to each other via screw connections which are detachable by hand without tools. There is a first top part comprising the table top plate, and a second center part comprising the supporting construction for the table top plate, this part includes a supporting inner tube which is concentrically received within an outer standing tube surrounding the inner tube. Furthermore, the standing table has a third bottom part including the base plate and possibly a step ring, this bottom part being connectable with the bottom end of the second part. For the screw connection among the three parts, it is possible to arrange, for example, top and bottom centering rings in the outer standing tube, such top and bottom rings each receive a threaded ring which is screwed to an outside thread of the inner tube.

Claims

1. Dismountable standing table comprising:

a first top part comprising a table top plate,

said table top plate having in a center means defining a through-extending circular hole, a top threaded ring fittingly received in said circular hole from the underside, a top part of said threaded ring having an inside thread, whereby said threaded ring is screwed to a screw cap with an outside thread, a head of said screw cap serving as an abutment for the threaded ring on the top side of the table top plate, and a top centering ring having on the top side a circular receptacle for fittingly receiving a lower part of the threaded ring;

a second center part comprising a supporting construction for the table top plate,

said construction comprising a supporting inner tube concentrically within a standing outer tube surrounding said inner tube;

and said top centering ring having an inside thread screwable to an outside thread of the inner tube concentrically within the standing outer tube;

a third lower part comprising a base plate, said base plate being connectable with a lower end of said second center part, said outer standing tube of said second part fittingly receives at the top said top centering ring, and the standing outer tube receives in the lower end a bottom centering ring;

said bottom centering ring in the lower end of the standing outer tube having a receptacle pointing downwardly and adapted for fittingly receiving a bottom threaded ring;

a bottom threaded ring being rigidly joined with the base plate, and said threaded ring having an inside thread and being screwable to a matching outside thread of a lower segment of the inner tube;

whereby the standing table has three parts screwable to each other via screw connections detachable by hand without tools.

2. Dismantleable standing table according to claim 1, wherein the screw cap is mushroom-shaped.

3. Dismantleable standing table according to claim 1, further comprising:

a bottom part comprising the base plate having a step ring extending concentrically all around the outer standing tube and being a spaced distance above the base plate.

4. Dismantleable standing table according to claim 1, wherein the screw cap has a concentric bore extending through in the center for receiving a shaft of a sun umbrella.

5. Dismantleable standing table according to claim 1, wherein the head of the screw cap has a groove on the underside for receiving a sealing ring.

6. Dismantleable standing table according to claim 1, wherein the threaded ring has a wider bottom part serving as an abutment on the underside of the table top plate and having a shoulder upper part of the threaded ring having a smaller outer cross section, such that the shoulder is received in the circular hole of the table top plate.
