Description

The invention relates to a table according to the preamble of claim 1.

In the case of corresponding tables, the tables generally consist of two table parts which can be moved relative to one another. Usually a telescopic guide is used. Extending the table has the effect that the usable table surface can be extended by, for example, extending a table top supplement part from the extended part and adding it to the fixed table part located on the other table part.

Each table section usually has table legs or other stands that are moved away from each other when the table is pulled out. The stands thus move away from the point at which the table top supplement part is then attached to the fixed plate, that is to say from the joint area of the table top supplement part and the fixed table top.

This joint area is therefore more or less in the middle between the stands when the table is extended. Especially with long tables and especially with heavy table tops, which are often solid wood tops, this area causes the table top to sag. This can make a difference of several cm in the vertical compared to the table edge. This is optically disadvantageous.

The object of the present invention is therefore to improve a table of the type mentioned at the outset in such a way that this sagging of the table in the extended state is avoided or at least significantly reduced.

This object is achieved by a table with the features of claim 1. Advantageous embodiments can be found in the subclaims.

The object according to the invention is a table with an extendable table frame, a first table part being coupled to a second table part via a pull-out mechanism.

The table frame comprises a first table frame part belonging to the first table part and a second table frame part belonging to the second table part, the first table frame part being designed to carry at least one table top supplement part which can be moved from a stowed position and the second table frame part carrying a table top which in an extended position is supported by the Tabletop supplement is added.

Furthermore, each table part is connected to at least one set-up element. In addition, the first table frame part comprises a first guide and a first guide element, the second table frame part comprising a second guide and at least a second guide element.

In the table according to the invention, the first guide element is guided in or on the second guide and the at least one second guide element is guided in or on the first guide, the second guide being designed such that the first guide element guided thereon or therein when the table frame is pushed together, in particular in the direction of a base, lowered and raised when the table frame is pulled out, in particular away from the base.

Through the use of one guide in each table part - a first guide element being arranged in the first table part and at least one second guide element being arranged in the second table part and the guide elements being guided in the guide of the other table part in each case - reliable guidance of the table parts relative to one another is ensured ,

It has proven to be advantageous if the first and / or the second guide comprises a guide groove. A guide groove has the advantage that it holds the guided guide elements in the guide groove with a certain, quite minimal, play in such a way that they are held in the guide groove even when an undesired, undirected force is exerted. The better holding effect is also achieved if another guide means, in particular a guide spring, is used instead of a guide groove. In the case of a guide spring, the guide element engages around the guide means and is guided in this way, the configuration of the guide element always having to be matched to the guide means.

According to a further advantageous embodiment of the present invention, it can be provided that the first guide element and / or at least one second guide element comprises / comprise a roller and / or a sliding element. The friction of the guide elements in the guide, in particular the guide groove, is significantly reduced with a sliding element. In particular, by using rollers, the friction is largely reduced, so that pulling out and / or pushing together the table frame parts is made easier.

According to a further advantageous embodiment, at least two horizontally spaced apart, interacting with the first guide are on the second table frame part Guide elements arranged. The connections between the two table frame parts, which then act at three points in the pull-out direction, increase the stability, especially in the extended state of the table, in the position at which the table top and the table top supplement part meet. In addition to the direct arrangement of the two spaced-apart guide elements on the second table frame part, the two guide elements can also be connected via a rocker, the rocker being arranged in the middle or close to the center of the second table frame. Such an embodiment of the fastening has the advantage that the risk of tilting when pulling out or pushing together is reduced.

Provision can also be made for the second guide to have a first guide section on its end region facing the first table part in the extended state and a second guide section lying lower on the opposite end section in the direction of the base of the table and a transition section connecting the two guide sections. When pulling apart or pushing together, the raising or lowering of the table top supplement part is specifically controlled so that there is no collision of the table top and table top supplement part when pulling out and / or pushing together.

According to a particularly advantageous embodiment, the curve described by the, in particular S-like, shape of the second guide has a turning point in the region of the transition section. With such a design of the guide, the raising / lowering of the table top supplementary part takes place rapidly when it is pulled out / pushed together at a predetermined point. However, it is also possible to distribute the lifting over almost the entire extension distance.

It can also be advantageously provided that the first guide has a first guide section which is distant from the second table part when the table is in the extended position and a second guide section at the opposite end and a transition section connecting the two guide sections. The curve described by the shape of the first guide has a vertex in the region of the transition section, in particular at the top relative to the bar. When the table top supplement is pulled out, it is tilted in such a way that the side facing the table top is raised slightly and the bending of the table in the middle can be counteracted even more.

According to a very particularly advantageous embodiment, when the table is pushed together, the first and the second guide lie in the direction parallel to the installation floor in such a way that the apex of the first guide coincides with the turning point of the second guide. When the vertex coincides with the inflection point, the table top supplement is tilted the moment it is lifted. It is advantageous if the curvature is matched to the turning point in such a way that the second guide elements are not jammed by the lifting of the first guide element and thus do not form an obstacle when the table frame parts are pulled out or pushed together.

According to a further embodiment of the present invention, the first guide is formed in or on a wooden strip. This means that, particularly in the case of a wooden table in which the table top and the table top supplement are made of wood, no material mix is introduced which could disturb the character of the wooden table.

It can also be provided that the second guide is formed in or on a wooden strip. This also emphasizes the character of a wooden table.

• 2 a side view of a second table frame part;
• 3 shows the two in the 1 and 2 shown table frame parts in the pushed together state;
• 4 shows the two in the 1 and 2 shown table frame parts in the extended state;
• 5 shows the side view of a table according to the invention in the extended state.

5 shows the side view of a table 1 in the extended state, the first table frame part 10 and the second table frame part 20 are so far apart that the table top 4 and the tabletop supplement 5 come to lie next to each other. A force P1 , which acts in the middle of this table arrangement, is from the set-up elements 2 . 3 that are on the outer edge of the table 1 are intercepted. Due to the large horizontal distance between the installation elements 2 . 3 from the action of the force P1 what alone the weight of the table top 4 and the tabletop supplement 5 the table can match 1 bend what should be avoided by the construction described below.

The support part (in the following non-restricting bar 11 called) of the first table frame part 10 who in 1 is shown, has a first guide 12 on, which is designed as a guide groove. At the right end of the figure, the bar points 11 a first guide element 13 on that from the leadership 22 the in 2 shown second bar 20 to be led. The guide points to the left 12 a first guide section 12a that rises to the right. The guide points to the right 12 a second guide section 12b that drops to the right. The two guide sections are connected 12a . 12b through a transition section 12c , Because in the transition section 12c the rising leading section 12a with the sloping guide section 12b come together, forms the transition section 12c one, especially upper, turning point of the leadership.

2 shows the carrier part (in the following not restrictive bar 21 called) of the second table frame part 20 , On the left side of the bar 21 are two second management elements 23 . 24 horizontally spaced and to the right of it the second guide 22 , The leadership 22 is in three sections 22a . 22b . 22c divided up. The focus on the management elements 23 . 24 subsequent first guide section 22a is arranged higher than the second guide section arranged at the opposite end region 22b , The two guide sections are connected 22a . 22b through a transition section 22c , The second has leadership 22 an S-like course, with the turning point in the transition section 22c located. In the second tour 22 becomes the first guide element 13 of the first part of the table frame 10 guided while the second guide elements 23 . 24 in the first tour 12 be performed.

The 3 and 4 show the interaction of the two table frame parts 10 . 20 or their two carrier parts 11 . 21 , In 3 are the two bars 11 . 21 pushed together what the inserted state of the table 1 equivalent. The two second guide elements 23 . 24 of the second table frame part 20 are in the lead 12 in the first management section 12a arranged while the first guide member 13 of the first part of the table frame 10 in the leadership 22 in the second, lower guide section 22b to be led. Will the table 1 now pulled out, the first guide element slides 13 along the second guide section 22b towards the transition section 22c while the two second guide elements 23 . 24 along the first guide section 12a towards the transition section 12c slide. In the area of the transition section 22c becomes the first guide element 13 raised and to the first guide section 22a directed.

The lifting of the first guide element 13 also causes lifting of the tabletop supplement 5 bearing ledge 11 so that the tabletop supplement 5 when it is put in the use position, level with the table top 4 comes to rest. It can be the table top supplement 5 a folding insert or a shelf stowed between the strips. At the same time, the second guide elements 23 . 24 through the transition area 12c led and so the bar 11 tilted so that it is slightly lowered towards the left end in the figure. There on the bar 11 on the left side the stand 2 arranged, this means that when moving the center of the table 1 is raised slightly. The bending of the table due to weight 1 now causes the table surface, formed by table top 4 and tabletop supplement 5 , is level again. In the remaining movement of the pull-out, the two second guide elements 23 . 24 in the second management section 12b the leadership 12 guided and the guide element 13 in the first guide section 22a , Because by going through the transition sections 12c . 22c the specified position of the table top supplement 5 In terms of inclination and height, the two guide sections can be as good as possible 12b . 22a quite short compared to the other sections 12a . 12c . 22b . 22c fail.

Because of the shaped slats 11 . 21 would the table 1 be slightly raised in the middle in an unloaded state. Due to the burden P1 due to the weight of the panels 4 . 5 and possibly other objects that are on the plates, the table bends 1 in the middle so far that the table top 4 and the tabletop supplement 5 form a level.

When describing the pulling out of sliding the guide elements 13 . 23 . 24 spoken, which implies that these are sliding elements. It is with a table according to the invention 1 just as possible that the guide elements 13 . 23 . 24 Roles are so that when you undress in the respective guide 12 . 22 roll.

Pushing the two table frame parts together 10 . 20 takes place in the reverse order of pulling out.

For stability reasons, the strips can be made of steel or aluminum. Is it a table according to the invention 1 around a wooden table, so it is beneficial if the moldings 11 . 21 are also designed as wooden strips, so that there is no mix of materials and the character of the wooden table is emphasized.
