Description

TECHNICAL AREA

The present invention relates to a table according to the preamble of claim 1. In particular, the invention relates to a bar table.

STATE OF THE ART

A bar table with three legs and hinged table top, which table is still on his three legs even with folded table top and where the legs converge towards the table top in a lower area is known, the three legs, however, do not reach the table top, but on Walk together foot of a center column. The table top is supported by the center pillar and is connected by a hinge in its center to the head of the center pillar. The table top is round and has a radius corresponding to the height of the center column, so that the three legs do not hinder the folding of the table top.

With folded table top, the table can be put together with other similar tables to save space.

Critical to the known table, as generally with all tables with center column, is their stability, which is why the center column also relatively thick and clunky and that it is connected to the table top joint with a large pressure distribution plate.

A table of the type mentioned is out FR 2 598 301 known. In this case, two legs form a connection node, through which the third straight leg extends, wherein the upper and lower part of the third leg is respectively attached to a hinge at the connection node. After folding up the table top, the two parts of the third leg can be rotated about the hinges so that they lie in a plane formed by the first and second leg. The axis of rotation is orthogonal to the longitudinal extent of the third leg. Such a mechanism can not be realized with three identical legs and therefore does not look aesthetically pleasing.

PRESENTATION OF THE INVENTION

The object of the invention is to provide a table of the type mentioned, which requires at least the same stability with simpler, less chunky components and is thus suitable to an improved aesthetic impression convey. The folding function should also be easy to use and intuitive to understand. With the table top folded down, the table should be able to put together with other similar tables to save space.

This object is achieved by a table with the features of claim 1. The inventive table is therefore characterized in that the upper part of the third leg relative to the lower part about the longitudinal axis of the lower part is rotatable.

Preferred embodiments of the inventive table are characterized in the dependent claims. Particularly preferred is the design of the table as a bar table. It is further preferred that the upper part of the third leg is fixed by sliding friction against twisting under its own weight.

WAYS FOR CARRYING OUT THE INVENTION

The standing table shown in the figures has three legs 10, 20 and 30 and a round table top 40. The three legs are under one with a matching shape Relative angle of 120 ° each and extending from the bottom up against the table top 40 in a lower portion I at an angle initially star-shaped together and in an upper portion II star-shaped apart again so that they individually and with mutual distance to the table top 40th end up. They are only bent in a transition area III from the lower I to the upper area II, but otherwise straight. Just below the bent transition area III, they are connected to each other in the lower area I by a connection node 50.

The two legs 10 and 20 are connected to the table top 40 via tilting joints whose parts are denoted by the legs 13 and 23 and on the table top with 41 and 42 respectively. The axes of the tilting joints are aligned.

The third table leg 30 is composed of a lower 31 and an upper part 32 in the lower region I, so that the upper part 32 comprises the upper region II, the transition region and also a small part of the lower region I. The upper part 32 is detachably connected to the table top 40 and rotatable relative to the lower part 31.

Due to its rotatability, the upper part 32 can be turned away below the table top 40 in such a way that it can then be folded down around the tilting joints on the other two legs 10 and 20, as shown in FIG Fig. 3 is shown. In this position, the upper part 32 of the third leg 30 is in contact with the upper region of the second table leg 20 and the table top 40 rests on the third leg 30. The table is still standing on all three legs.

For detachable connection of the upper part 32 with the table top 40, a head piece 33 is provided with a flat, plate-like holding plate at the end of the upper part 32, and as a counterpart to the table top 40, an approximately horseshoe-shaped receptacle 43, with an undercut for the protruding Edge of the holding plate is provided. Together with the twisting of the upper part 32 to Aboder the table top 40, the holding plate of the head piece 33 in the undercut of the receptacle 43 on or moved out of this, so that no additional handles required for the manufacture or release of the connection 32 are. Preferably, the retaining plate of the head piece 33 engages in the receptacle 43 even slightly.

Further preferably, the angles at which the three legs 10, 20 and 30 are inclined in their lower I and upper portion II against the vertical, are selected so that the folded table top 40, as in Fig. 3 Also shown, is aligned parallel to the lower part 31 of the third leg. This is the case, for example, when the angle with respect to the vertical in the lower region I is 21 ° and in the upper region II is 36 °. The length of the straight section in the lower area I may be eg 814.4 mm and in the upper area II 247.9 mm with a radius of 50 mm in the transition area III.

When folded table top 40 several similar tables can be put together to save space, as this Fig. 4 using the example of two tables shows.

Regarding Fig. 5 Now, the rotatable connection of the lower 31 and the upper part 32 of the third leg 30 will be described.

Both parts 31 and 32 are tubular and have a round cross-section, which preferably also applies to the other two other legs 10 and 20. All three legs can be made of metal tube. In the upper part 32 is a welding rake 35 rotationally fixed, for example, by welding, used, in which a bolt 36 is also anchored rotatably, which projects down into the lower part 31. There is a bolt 36 receiving insert 37 is present, which has a recess under an elastic deformation on the bolt 36 fitting friction element 38. Upon rotation of the upper part 32, the bolt 36 rotates in the insert 37 and rubs against the friction member 38, so that the movement of the upper part 32 relative to the lower part 31 is damped by sliding friction. Preferably, the damping is such that the upper part 32 is fixed against twisting under its own weight in each rotational position, but still can be easily moved. The upper part 32 is thereby secured against uncontrolled rotation. A sufficiently large friction can be achieved by using a material such as polyurethane for the friction element 38. In addition, as in Fig. 5 also shown, the bolt 36 may be provided with circumferential grooves, in which the elastic material of the friction element 38 expands while further increasing the friction.

With the connection node 50, the three legs 10, 20 and 30 are screwed. Two screws 51 used for the third leg are in Fig. 5 to recognize, which is determined by these screws at the same time the insert 37 in the lower part 31 of the third leg 30. Against the screws 51 towards the clamping piece 37 is flattened so that it rests flat against the inner wall of the lower part 31.

The lower ends of the three legs provided with so-called gliders 14, 24 and 34.
