Description

Extending table Field of the Invention The present invention pertains to tables with expandable surface. Background of the invention Tables are known with a tabletop formed by two parts, which can be separated to create a space between

them where to lodge a supplementary board that allows to extend the useful surface of the table. There are several mechanisms to carry out this extension: with fixed or extensible reinforcement; with boards

extendable by sliding, extraction, folding or folding; with recessed, swing or supplementary boards sliders, etc. All the aforementioned tables have in common that they have one or more supplementary boards that

they allow to extend the surface and that only allow this surface to be extended thanks to the modification of only one of the dimensions of the table, either the width or the length.

DESCRIPTION OF THE INVENTION The object of the present invention is a table whose surface is expandable both in length and width in a selectable way. With this functionality the proposed table allows versatile use adapting to a greater number of situations.

In particular, it is possible to expand both dimensions or to only expand one dimension allowing in both cases that the table is operative.

BRIEF DESCRIPTION OF THE DRAWINGS A series of drawings that help to better understand the invention and that expressly relate to an embodiment of said invention that is presented as a non-limiting example thereof is described very briefly below.

Figure 1A - 1C shows a square table in its three possible positions. Figure 2A - 2C shows a rectangular table in its three possible positions. Figure 3A - 3C shows the table of Figure 1 without the boards for a better appreciation of its structure. Figure 4 shows an exploded view of the table structure (without boards). Detailed description of the invention The conversion of the table to one of its possible extensions is done through simple maneuvers as will be explained

then.

The following example describes as an optional step the width extension but could alternatively be the long the optionally expandable. Without loss of generality, it must be understood that they are interchangeable. The extension mechanism can be used for both square and rectangular tables. In the first case, the

first extension would turn the table into rectangular and in the second step it would be square again.

In a first step you can increase the length of the table (1) and in a second step, which is optional, you can Increase the width of the table. This establishes three different modes for the table. For this purpose, the table has two pairs of frames (5, 6) formed by independent segments (5a, 5b, 6a,

6b). These segments are longitudinally extensible. Preferably, a rail system is used to extend the length of the segments. These are guides formed by a profile (10), usually made of aluminum. Other mechanisms can serve this purpose, for example ball guides, telescopes, etc. Equally with other materials.

The table can be assembled in three different ways:

-

 Mode A of smaller surface.

-

 Mode B of intermediate surface.

-

 C mode of larger area.

Transition between modes A - B (length extension)

In its A mode, the table (1) has two supplementary boards (3, 4) housed under the main board (2). To reach mode B, the first frames (5) that form the table beams must be extended longitudinally. With this action the extended frames establish an empty space that the main board (2) does not cover. This empty space coincides approximately with the surface of the first supplementary board (3). Said first supplementary board (3) is removable under the main board (2), is placed next to it and is kept at the same height by coupling between the second non-extended frame (6) and the main board (2). In the example described here, this first supplementary board is responsible for extending the length (it could alternatively be the width in other embodiments).

Transition between modes B - C (width extension)

From mode B, mode C can be reached if even more useful area is desired. For this, the second transverse frames (6) extend longitudinally in a similar manner to the previous case. Thus another empty space is formed that does not cover either the main board (2) or the supplementary board (3). This empty space must coincide approximately with the total area of the second supplementary board (4). Before extending the second transverse frames (6) said second supplementary board (4) was housed under the main board (2). Once extended, this second supplementary board (4) is housed in the empty space generated, to cover it a deployment maneuver is carried out. During deployment, the second supplementary board has to be turned 180 ° to reverse the exposed face around the axis (9). This turn must be followed by the actual deployment of the supplementary board (4) so that its length coincides with the total length of the extended table of mode B. It must also be raised in height to the same level as the rest of the boards ( 2. 3. 4). The previous turn is used to carry out this necessary elevation for the correct coupling of the second supplementary board (4) with the first supplementary board (3) and the main board (2). (In other possible embodiments, mode C may correspond to widening the width). Since the second supplementary board must be housed under the table in both mode A and mode B, it turns out to be foldable. In the exemplary embodiment, this folding is achieved thanks to a second supplementary board constructed in two parts joined by hinges.

As can be seen in the drawings, the second supplementary board must have a folded length less than or equal to the length of the table in mode A and an unfolded length approximately equal to the length of the table in mode B.
