Description

table

The invention relates to a table with a table top and pull-out elements and with a frame construction with table legs.

Tables are known and well known in the art in various embodiments. They are used among other things as a living room or dining tables _^ and include such items as wood and / or plastic and / or glass.

Especially for dining tables extendable tables are known, the actual table top can be enlarged by the attachment of Ausziehelementen, for example, to be able to host a larger company. For this purpose, various forms of extension tables are known. For example, the actual table top of the table can be essentially divided into two symmetrically, wherein the two halves are pulled apart by a suitable mechanism for extracting the table and an extraction element previously stored below the table or the tabletop removed by the user and inserted between the two exploded table halves.

Furthermore, extendable tables are known in which a one-piece table top moved substantially horizontally and a pull-out with the substantially same dimensions, which was previously stored below the table top, is pulled out via a suitable guide means, so that subsequently the table is substantially twice the size having.

A disadvantage here is to be considered that although the table surface can be increased by taking off the table, but thereby to

Part significant static problems occur because in particular the

Pull-out elements can no longer be adequately supported. In addition is the base of the table by the pull-out often only insufficiently enlarged.

Based on this prior art, the skilled person has the task of providing a table of the type mentioned, the table surface is considerably enlarged and in which the stability of the enlarged table surface is guaranteed.

According to the invention the object is achieved by the features of claim 1.

The essence of the invention is that below the actual table top one or more extension elements are arranged, with which the base of the table or the table top can be enlarged. Preferably, at least two substantially similar trained Ausziehelemente are arranged below the actual table top, which can be pulled out in a symmetrical manner in order to enlarge a table top on both sides can. For this purpose, the table top can be raised in order to be able to spend the pull-out elements arranged thereunder essentially without resistance from its parking position in an extended position. In this case, the extension elements are mounted slidably below guide rails along the table top, wherein the guide rails are formed such that the extension elements are displaceable from the position below the table top via a substantially obliquely oriented cam track in an extended position, and the extraction elements in the extended position Completely flush with the table top, which in turn is lowered to its original position, complete to increase the table surface transition-free.

It is understood that the extraction elements are for this purpose on guide rails, for example in the form of aluminum rails, stored. For this purpose, in particular roller .Gleit- or ball bearings are provided to the To keep frictional resistance as low as possible. As materials for the table or the table top and the pull-out elements wood and / or plastic and / or metal and / or glass can be used.

The advantage of the invention is that the table surface can be substantially enlarged by lifting and subsequently removing the pull-out elements, without having to use loose pull-out elements which are used, for example, between a centrally divided tabletop. Preferably, for this purpose, the actual table top is made in one piece, but in principle the table top can also be formed in two or more parts.

Advantageous embodiments of the invention are the subject of dependent claims.

In a simple way, the table top can be raised with a lever mechanism. For this purpose, a pivotable lever can be arranged below the table or the table top, which is dimensioned such that a user can lift the table top by simply pivoting the lever. The lever lengths can be selected by the skilled person so that this virtually no effort is required. To guide the table top is proposed that it is provided at the bottom with pins which are inserted into corresponding guide holes in the frame construction, wherein the length of the pin is designed such that sufficient guidance or alignment is ensured even in the raised state of the table top. To extend the pull-out elements, the lever mechanism or the lever is designed such that it acts on an extension element and, by pulling the lever, the pull-out element can be displaced into the extended position along the guide rails. To push the table together, the table top is raised again, the pull-out moved into position below the table top and lowered the table again. It is understood that each pull-out element on both sides of the table can be assigned its own lever mechanism or its own lever, but in principle this lever mechanism can also be designed such that by operating the lever on one side of the table, for example via cables or the like , the other pull-out on the opposite side of the table top is pulled out synchronously with.

To reduce the frictional resistance is proposed that on the lever mechanism with which the table top is raised, a roller is arranged so that when pulling the lever to pull the pull-out, this roller rolls on the underside of the table top to here as possible to obtain low resistance. With appropriate rotatable mounting of the roller thus the frictional resistance of the lever when lifting the table top is also reduced. In the same way, rollers, wheels or the like can be used.

To substantially increase the table surface of the table, it is proposed that, in addition to the first pull-out elements, further second pull-out elements are provided, which are mounted on guide rails below the first pull-out elements in a similar manner and with the aid of the same lever mechanism from their position below the first

Extractors can be moved to their extended position. If such pull-out elements are arranged in pairs, a table of, for example, 140 cm in length with first and second pull-out elements of 65 cm in length can be increased to a length of up to 400 cm. It is understood that the table can be made virtually any widths.

To increase the stability of the table in existing second pull-out is proposed that this second pull-out each one, preferably two, pivotable legs are assigned, which are folded in the non-extended position under the second pull-out. If the second pull-out elements are displaced into their extended position, the table legs or legs can be folded out and serve to support the second pull-out elements, so that heavy objects can also be placed on the second pull-out elements here.

For a simple embodiment of the unfolding of the table legs, it is proposed that this is done by means of a known scissors mechanism, with which the table legs can be pivoted into a substantially vertical position or folded back into its retracted position upon reinsertion of the second pull-out elements. This is preferably done automatically when removing and retracting.

To adapt to different circumstances, for example, when the floor is covered with a high-pile carpet, the table legs are telescopic, with an arbitrarily shaped telescopic device is preferably arranged in the foot of the table legs. This can be done for example via a screw mechanism or via any designable extract elements to allow height compensation.

To increase the comfort of use of the table, the lever mechanism is controlled by an electric motor. This means that the table top can be raised by means of an electric motor and subsequently the pull-out element or elements can be displaced to their extended position via an electric drive. In particular, this can be provided for a remote control, which transmits the commands, for example, with infrared or radio signals. Of course, the folding and unfolding of the additional table legs also takes place by electric motor.

To avoid incorrect operation of the table, a mechanical Secured to be provided on the lever mechanism, which can be configured by the skilled person in any desired manner.

The invention will be explained in more detail below with reference to an embodiment with reference to the accompanying drawings. Show it:

Fig. 1: a table from below,

Fig. 2: a table with first pull-out elements, and

Fig. 3: a table with second pull-out elements.

In the embodiment of the invention shown in Figures 1 to 3 is a table 1 with a preferably integrally formed table top 2, for example, 140cm in length. Below the table top 2, first and second pull-out elements 3a, 3b, 4a, 4b of, for example, 65 cm in length are arranged. The table top 2 is supported on a frame construction 5 with four legs 6 here. In principle, it is also possible that the frame structure 5 is completely eliminated and the table top 2 directly on the table legs 6, the number of which can also vary, is supported.

For extending the pull-out elements 3a, 3b, 4a, 4b serve guide rails 7, for example in the form of aluminum profiles, wherein the pull-out elements 3a, 3b, 4a, 4b are preferably mounted on rollers or the like to reduce the resistance. For actual extraction of the pull-out elements 3a, 3b, 4a, 4b is a lever mechanism with a lever 8 which is pivotable via a handle, as indicated by the double arrow V, and is extendable, as shown by the double arrow A. At the end, the lever 8 is provided with a roller 9, a roller, a wheel or the like made of a material suitable for this, in order to reduce the frictional resistance below the table top 2. To pull out the table 1, the lever 8 is pivoted in such a way that the table top 2 is raised via the roller 9, For example, by 26mm, ie a thickness of the table top 2 and a pull-out 3a, 3b, 4a, 4b, and subsequently the lever 8 is pulled A, so that the pull-out elements 3a, 4a along the guide rails 7, as shown in Figure 2, in their extended position will be relocated. In this case, the guide rails 7 are formed obliquely such that in the extended position, the first pull-out elements 3a, 3b, as shown in Figure 3, substantially flush with the table top 2 complete. For this purpose, the pull-out elements 3a, 3b, 4a, 4b are guided over the guide rails 7 along a curved curve.

For guiding and supporting the table top 2, this is for example mounted on pins on or in the frame structure 5, wherein the pins engage in corresponding recesses in the frame structure 5 and are formed in such a length that the table top 2 stored reliably even in the raised state is. After the pull-out elements 3a, 4a are in their extended position, the lever 8 is pivoted back again V, the table top 2 is lowered and the thus enlarged table surface can be used.

In the same way, the pull-out elements 4a, 4b can be pulled out, wherein these pull-out elements 4a, 4b each pivotable table legs 10 are assigned, which can preferably be folded down via a scissors mechanism 11 when pulling in a substantially vertical position. If the pull-out elements 4a, 4b are pushed in again, the table legs 10 automatically fold back into a substantially horizontal position via the scissors mechanism 11. In addition, the table legs 10 telescopic devices may be assigned to compensate for example, different carpet heights can.

Of course, the table 1 also with the help of an electric motor Drive, which is optionally designed remotely controlled, pulled out or inserted again.

In the foregoing, the invention has been described essentially in connection with a pull-out table 1, it is understood, however, that the invention also for table extensions, which are for example attached to a wall, or other installation elements in a kitchen, a wall unit or for office furniture, camping equipment or marine equipment can be used.
