Abstract

The device has a retaining unit connected to a plate and a supporting rod, where the retaining unit has a holding retainer that is limited by two retaining side pieces (4, 5) and is axially parallel to the supporting rod. The holding retainer is provided for partially enveloping the supporting rod. The retaining side pieces for mounting and/or demounting the plate on and/or from a supporting frame are designed in an adjustable manner.

Description

The invention relates to a connecting device for attaching a plate to a parallel to it extending support strut of a piece of furniture, in particular a table top on a support frame, according to the preamble of patent claim 1.

A connecting device of the type mentioned is according to the DE 299 06 833 U1 known. This consists of a one hand on the plate and on the other hand attachable to the support strut retaining element, wherein the holding element has an axially parallel to the support strut, two holding legs and an intermediate web portion limited holding receptacle for partially embracing the support strut.

To attach the retaining piece on the support strut is after the DE 299 06 833 U1 provided (see page 6, last paragraph), that the two holding legs are formed in its end region of the holding receptacle starting outward widening. The holding receptacle in this case comprises the support strut by more than 180 °, wherein the retaining legs have sufficient inherent elasticity, so that they can diverge resiliently when pressing the retaining piece on the support strut and then move back against each other, so that the retaining piece is fixed to the support strut.

In other words, the retaining element is after the DE 299 06 833 U1 In a manner similar to an elastic retaining clip which can be snapped onto the support strut. Depending on the embodiment, the clipping on the support strut takes place from above or from the side, wherein the holding element itself is screwed to the plate.

The invention has the object to improve a connection device of the type mentioned in terms of their handling and variability.

This object is achieved with a connecting device of the type mentioned by the features listed in the characterizing part of patent claim 1.

According to the invention, it is thus provided that the holding legs for mounting or dismounting of the plate on or from the support strut are mutually adjustable. Particularly preferably, it is provided that the holding legs in a plane parallel to the plate are mutually displaceably adjustable.

In other words, the inventive solution differs from the prior art in particular in that the connection device is no longer snapped onto the support strut, but the attachment to the support strut by adjusting the support legs to each other. There are therefore according to the invention in particular two positions of the holding leg, namely first, the position in which the connecting device can be attached to the support strut, but only partially encompassed by a holding leg, and second, the position in which by moving the other holding leg the desired enclosure ( about 180 °) of the support strut takes place.

In the adjustment according to the invention, the holding legs are not practically (elastically) deformed; they are thus virtually intrinsic deformation free. The mounting or dismounting possibility results from the adjustability of the holding leg to each other.

Other advantageous developments of the connecting device according to the invention will become apparent from the dependent claims.

The connecting device according to the invention including its advantageous developments according to the dependent claims will be explained in more detail with reference to the drawing of a preferred embodiment.

The connecting device shown in FIGS. 1 to 19 for attaching a plate 1 to a support strut 2 of a piece of furniture, in particular a table top on a support frame, which runs parallel to it and typically has a rectangular cross section, comprises on the one hand Here, the typically (but not necessarily) made of plastic holding member 3 has a support strut 2 axially parallel, two holding legs 4, 5 limited holding receptacle for at least partially embracing the support strut 2 on.

It is essential for the connection device according to the invention that the holding legs 4, 5 are designed to be mutually adjustable for mounting or dismounting the plate 1 on or from the support strut 2. As shown, there is a preferred embodiment in that the holding legs 4, 5 in a plane parallel to the plate 1 are mutually displaceably adjustable.

To form the retaining legs 4, 5 it is provided that the holding element 3 consists of two mutually releasable components 6, 7, wherein the one component 6 (see in particular FIGS. 14 to 19) for attachment to the plate 1 through holes 17 for fastening means such Has screws and one of the two retaining legs 4, wherein the other component 7 (see in particular figures 8 to 13) the other holding leg 5 and wherein between the two components 4, 5 a parallel to the plate 1 extending sliding guide 8 (see Figure 5 and 6) is provided.

In order to easily operate the sliding guide 8, which is provided on both components 6, 7, mutually positive webs 13 and grooves 14, a gripping element 9 is arranged on the component 7, which is operatively connected to a built-in sliding guide 8 latching mechanism , This locking mechanism is formed on a component 6 from a arranged on an elastic, leaf spring-like cross member 12 projection 10 and the other component 7 of two positive recesses 11 thereto. As can easily be imagined, one recess defines the opening position and the other defines the closing position of the connecting device. With the handle element 9 thus the component 7 can latching between two end positions are adjusted with respect to the component 6.

In order to ensure a certain elasticity between the connection of plate 1 and support strut 2, at least one of the holding legs 4, 5 support struts side, an elastic element 15. In this case, the holding legs 4, 5 and the elastic element 15 are preferably integrally formed, wherein the elastic element 15 leaf-spring-like in front of a recess 16 on the holding leg 4, 5 extends from one to the other side of the holding leg 4, 5.
