Description

The invention relates to a space-saving collapsible table for the Indoor and outdoor use under the influence of weather, which at Not used or stowed away to save space for transport. The is planned Mechanism for example for tables, chairs, stools or stands.

With such foldable furniture, it is necessary to the substructure with which the Usable space should stand securely, saving space as easily as possible to be able to fold and leave in connection with the usable area. in the installed condition, it is necessary to have the greatest possible stability and To ensure stability and at the same time an unintentional folding to prevent.

Such folding furniture is general and z. B. also from AT 221248 and FR 821314 known. The stability and appearance of these furniture bases is not optimal.

The invention is therefore based on the object arranged around a vertical axis Furniture bases are stable and foldable with due consideration of the design to execute.

This object is achieved by the features of claim 1.

On a piece of furniture with such a folding mechanism, the table surface is in one attached by several support legs, and lies on top of others during use, whereby stability is achieved, since hereby the pivoting movement around the Pivot axis of the table surface is blocked. To lift the table surface from the To prevent contact points on the support legs when lifting the furniture Lifting safeguards are provided on the underside of the table surface, in which the support legs swing in when setting up. The support legs are in the described embodiment executed so that they have an adjacent support leg over a driver in the end position swing along, and have a stop to which the other side Support leg strikes in its end position, the relative position of the stops and Driver on the support legs to each other is arbitrary. In the end position, the Support legs secured by a locking mechanism that prevents accidental Preventing the support legs from swiveling together.

An embodiment of the invention is shown in the drawing and is in following described in more detail.  

Fig. 1 shows a view of a round, three-legged, rotationally symmetrical folding table with the most important components for the mechanism described with a view of the underside of the table surface ( 3 ). In this example, the table surface ( 3 ) is articulated on a support leg ( 4 ) in two bearing points ( 5 ) and, if the support legs ( 4 ) are folded together, can be folded into a plane parallel to the latter. The collapsed state is reached. In other versions, this state can also be secured by a locking mechanism. In the unfolded state shown, the support legs ( 4 ) are secured in their end positions by lifting safeguards ( 7 ) in order to avoid lifting them off the support legs ( 6 ) when the table surface ( 3 ) is raised. The support leg ( 4 ) which swivels the furthest is protected in its end position by a locking mechanism ( 9 ) against unintentional swinging back. Driver and stops (8) are mounted on the support legs (4), which position the existing support legs (4) when setting up in its angular position to one another and fix. The line passing through the pivot point of the support legs (4) axis (6) is such offset parallel to the central plane of the supporting legs (4), that the support legs (4) abut in the folded state parallel to each other, and that in the use state, the axis through the intersection of the median planes the support legs ( 4 ) run through the center of the table surface ( 3 ).

Fig. 2 shows a view of a round, three-legged, rotationally symmetrical folding table with the most important components for the mechanism described in a side view, wherein all support legs ( 4 ) are pivoted about their vertical pivot axis ( 2 ) in the plane of the drawing, in which the pivot axis ( 1 ) the table surface ( 3 ) runs. The table surface ( 3 ) is visible in its usage position as a partial representation. The vertical pivot axis of the support legs ( 2 ) maintains the curved shape of the support legs ( 4 ) of the rotationally symmetrical table design. The support legs ( 4 ) are articulated with one another in their pivot axis ( 2 ) in bearing points ( 6 ). When swiveling around the pivot axis ( 2 ), the drivers ( 8 ) take their neighboring support legs ( 4 ) with them until they strike the stop ( 8 ) on the support leg ( 4 ) that is adjacent on the other side, whereby their angular position is fixed to one another in the set-up state. In the example shown, the pivot axis of the support legs ( 2 ) runs through the center of the usable area, as a result of which the furniture appears asymmetrical when it is set up.

The advantages achieved by the invention are in particular that rotation symmetrically shaped furniture bases with the mechanism described fold bar can be carried out, while the design is largely preserved. In particular special furniture with rotationally symmetrical three-legged base, which, because static does not match, do not tilt on uneven ground, can with the described Mechanism foldable.

Handling when folding is simplified compared to the described level scissors mechanism, as the possibly heavy usable area is no longer available must be raised, but when swiveling the legs together in the same Remaining level, then advantageously around an axis of symmetry in its End position is pivoted.

Claims (4)

1. Collapsible table with an odd number of support legs, for use indoors and outdoors under the influence of the weather, by means of a pivoting movement of part of the articulated table base around a vertical axis and a further pivoting movement of the table surface articulated on a support leg relative to Furniture substructure can be collapsed about a perpendicular to this vertical axis, horizontal axis, characterized in that there are carriers and stops ( 8 ) with which the position of the support legs ( 4 ) is fixed in the folded state and in the state of use, that when swiveling the table in the state of use by pivoting a support leg provided ( 4 ), the other arranged on the pivot axis th pivotable support legs ( 4 ) are pivoted into their intended position for use ge. 2. Collapsible table according to claim 1, characterized in that two or more support legs have drivers and stops ( 8 ) with which the Winkelpositi on the support legs ( 4 ) to each other is defined. 3.
