Abstract

The expandable plate, in particular, for items of furniture such as tables, seats and shelves comprises lamellas or rods which are joined to one another at least within one end zone, and are elastically constituted so that the plate area is steplessly increasable by applying a pull to the plate ends.

Description

The state of the art includes resizable surfaces such as extendable panels, e.g. for furniture such as tables, chairs, benches, walls, compartments or the like, to enlarge the panel surface.

In the case of extendable tables, for example, where both sliding table tops move apart in opposite directions, special and complicated handling is required to enlarge them. In addition, there is the problem that the extension is always predetermined and cannot be achieved depending on the situation (number of people using the table).

The corresponding panel elements must either be stored separately, inserted if necessary, or removed. It is also known that panel elements can be pulled up or swung up from a storage drawer located in the lower part of the table and then folded out to fill the free space.

For all known plates, it is cumbersome to enlarge their surface area.
For example, in the case of the table with a convertible table top according to DE 3743788C2, it is not possible to vary the enlargement of the changeable top and, on the other hand, several manual steps are required to enlarge the surface.

In the folding table for vehicles according to DE 19516011C1, the surface consists of slats that can move against each other and are tensioned with a belt, the entire arrangement of which does not allow a change in size.

With the extendable table according to DE3438551C2, the ability to change the surface is limited in that either only a non-enlarged surface is possible or the surface must be pulled out completely. Intermediate steps are not possible.

The present invention is therefore based on the object of creating a furniture panel which can be enlarged by simple handling without inserting or unfolding separate panels and which can be easily brought into its enlarged position and vice versa into the original position.

This object is achieved according to the invention in a plate according to the preamble of patent claim 1 by the characterizing features of patent claim 1.

This allows a continuous enlargement of the plate surface by spreading the non-connected areas (7).

The enlarged surface is created solely by a simple pulling or pushing movement at one of the plate ends without any further handling.

The surface is flat and/or curved depending on the design of the bracket and/or guide and has sufficient rigidity depending on the design.

Advantageous embodiments of the plate according to claim 1 are reproduced in the subclaims.

Bendable slats are a prerequisite for the adjustable panel. The panel guide is particularly suitable for flat surfaces. A curved guide or bracket is particularly suitable for a panel that is used as a room divider or similar.

The design according to patent claim 2 enables the production of wider furniture panels.

Thin bars with a square cross-section allow the panel to be designed as a screen or as a curved structure.

Bonded and/or glued areas of the furniture panel are particularly advantageous when using wood

When using other materials, other types of connections can also be advantageous, such as wedges, rivets or screw connections.

However, guides with sliding connections are also conceivable.

A guide as a rail on a frame is particularly advantageous for tables.

With the design according to claim 9, lifting of the plate can be prevented.

Description:

Examples of embodiments are described in the drawing using the figures.

This shows:

Figure 1 a plate with slats in spread state, Figure 2 the detail A from Figure 1,

Figure 4 shows the front and rear view of half a slat, Figure 5 shows three slat arrangements schematically,

Figure a lower plate guide with four dash-dotted slats on a non-enlarged table,

In Figure 1 the slats are shown in the spread state.

The end strip or end slat (1) is connected to the second slat (2) in two areas

(6) and are not connected in three areas (7).

The second slat (2) is connected to the third slat (3) in three areas (6) and is not connected in two areas (7).

The third slat (3) is connected to the fourth slat (4) in two areas (6) and is not connected in three areas (7).

The fourth lamella (4) is connected to the &eegr;-th lamella (5) in three areas (6) and is not connected in two areas (7).

The other slat connections are analogous to this.

In Figure 2, detail A shows a panel corner from Figure 1

Figure 3 shows the arrangement of the slats (1,2,3,4,...,5) of half a table top.

The adjustable furniture panel essentially consists of slats (1,2,3,4,...,5) which are connected to one another in areas (6,6') when standing upright and are not connected to one another in other areas (7). In the top view of the extendible furniture panel, different distances (9) are formed when it is moved (8). They enable the panel length to be changed continuously.

The area of the gluing/bonding (6,6') is selected in such a way that a certain tension ensures the even extension of the slats.

The resulting variable distances (9) are selected when the table top is extended to its maximum so that a secure stand of various objects placed on the table is guaranteed at all times.

Figure 4 shows the front and rear view of a half slat, with its indicated connection points (6,6'), and with the non-connected areas (7).

Figure 5 shows three schematically illustrated lamella arrangements in the spread state.

Figure 6 shows the arrangement of a bracket and slat guide as a base for a table top.

It consists of three frames (10,11,12) on which the adjustable plate rests.

The frame (11) and the frame (12) are connected to a shelf extension (13) which can be continuously extended and which gives the frame the necessary rigidity due to its upright installation position.

In order to enable horizontal movement of a table, for example, and to prevent the extendible plate from being lifted and moved sideways when it is extended as far as it can be, a rail (15) is grooved into the frames at a certain angle (14) to the frame surface and is firmly connected to the frames (10, 11, 12).

The angled groove (16) in the slats is with a tolerance (17) at the same angle

(14) worked like the grooved rail to prevent the slats from jamming when being pushed in or out.

Furthermore, the frame (10) can be connected to the frame (12) by a thin strip

(18) made of a stable material by means of a firm screw connection from below in order to ensure a parallel position of the frames in any condition.
