14 828 is a 2-table movable worktop made of solid wood. There is used a bar, so-called running rails, which allow adjustment of the worktop as in the horizontal direction. however, this arrangement requires a relatively large table depth. This contradicts the desire to ensure as low a table as possible, it hire office desks and desks.

In addition, the movement of the worktop adjuster takes place in several steps, that is, it must be pulled forward, folded and retracted again.

The essence of the invention

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a table with a movable worktop, preferably of solid wood, wherein the worktop is to be reliably and reliably secure at a certain incline and in a horizontal plane relative to the storage plane. on the power of easy manipulation. The possibility of a reduced working table depth should also be achieved while creating ergonomically user friendly. In addition, the construction should be as simple and economical as possible.

The object of the present invention is to provide a movable worktop according to the invention, wherein the worktop is simultaneously adjustable in a horizontal direction in a longitudinal guide arrangement and in an angular position relative to a horizontal plane about a pivot center in the forward region of the longitudinal guide arrangement. by means of a substantially wedge-shaped guide rail.

The longitudinal guide arrangement consists of a joint with a longitudinal groove and a pin which is arranged on two opposite lateral edges of the front sides of the worktop between it and the table base, the pin forming the center of rotation and the pin sliding in the longitudinal groove. On the underside of the worktop, on each of their opposite faces, there is provided one guide blade arrangement, the shape of which extends towards the rear with respect to the horizontal plane 20 of the user side. At least one cross brace is provided on the table base. which can be brought into contact with one free wedge surface of the guide rail arrangement, which performs a sliding movement on the transverse reinforcement.

According to a further advantageous embodiment, the longitudinal groove can be connected by a longitudinal groove and a pin in each case in the region of the front side of the worktop which is close to the user.

The pin guided in the longitudinal groove can be arranged on the other side of the worktop.

which is opposite to the base of the table.

The longitudinal groove is provided approximately one third of the length of the front side of the worktop.

According to a further advantageous embodiment, the longitudinal guide arrangement consists of a joint with a longitudinal groove and a pin, which in the direction of its movement is always parallel to the two opposite side edges of the worktop between it and the table base on the corresponding underside of the worktop and between the base table in the immediate vicinity of the front side edges.

In this case, each joint with the longitudinal groove and the pin consists of protruding guide elements, one water element having a longitudinal groove and the other with it.

The cooperating guide element has a pin.

According to a variant, the guiding element with the longitudinal groove can be arranged and the plate can be arranged on the table base. According to a further variant, the guide element with the longitudinal groove can be arranged on the table base and the guide element with the pin can be arranged on the worktop.

The free wedge surface of the guide rail arrangement may have a transverse groove for the positive fit of the horizontal and angular position of the transverse reinforcement in the worktop. In a particularly preferred embodiment, the bottom surface of the transverse groove is angled with respect to its side surfaces to form a sharp angle with the horizontal plane. The acute angle of the bottom surface of the transverse groove roughly corresponds to the inclination angle of the worktop in an angularly set position.

The angle of inclination of the worktop in the angularly adjusted position is 5 to 15 °, preferably 8 °.

Finally, the at least one guide rail arrangement may have a locking portion engaging and attachable to the table base, which attaches the worktop in its angularly adjusted position.

By means of this solution according to the invention, the adjustment of the worktop can be carried out in one single movement. It is immaterial whether the worktop is heavy, since the free wedge surfaces of the guide rails slide along the transverse stiffeners, as long as the transverse groove provided in the wedge surface does not fit into contact with the transverse stiffener and fits into it. . Nevertheless, the transverse groove is not necessary, as the transverse stiffener may also abut at any point in the free wedge surface of the guide rail arrangement. Pulling the worktop towards the user will automatically move it to its angular position. The angle of inclination of the wedge surface in connection with the transverse grip is at the same angle as the inclined position of the applied worktop.

By simply retracting the worktop, the worktop is retracted into its mounting plane on the table base. A longitudinal v / ribbon arranged on the table base can also be used between the legs as a cross brace

The connection with the longitudinal groove and the pin between the worktop and the pedestal, which is provided close to the user, serves for the horizontal mobility of the worktop. By adjusting the pin, a center of rotation is formed around which it is possible to adjust angularly with the horizontal movement of the worktop. The adjustability of the worktop is thus substantially determined in the longitudinal groove guided by the pin and the free wedge surface of the guide rail arrangement.

The inclination of the worktop should preferably be in the range of up to about 15 °

8 °, because experience shows that these values create the best ergonomic conditions.

It is precisely with the use of tables, in particular office tables, whose seating surface is adjustable, in the case of conventional tables, the adjustment of these elements is of no importance if the user has to assume a working position on the table.

especially on the desk, as it must also leave the back of the chair with its back to lean against the desk. By allowing the wearer to tighten and angularly adjust the worktop, the wearer can maintain the back position resting on the chair back and thus create an ergonomically favorable upper body relieving the position in which the body need not be stretched.

DETAILED DESCRIPTION OF THE INVENTION

The following exemplary embodiment relates to a table with a movable worktop 3, the actual worktop 1 being divided into three elements, of which the central element forms an adjustable worktop 3. Right and left of the worktop 3 are treated parts which also form a certain area In the exemplary embodiment, they are considered to be parts of the table stand 5. In addition to Lono, the exemplary embodiment relates to a table made of solid wood. It should be noted that, in principle, all the components described may consist of solid wood.

As already mentioned, a three-part tabletop 7 is formed, the central part of which is formed by a worktop 3. The right and left-hand tabletop parts are associated with the respective table base 5. The legs 7, the rear transverse stiffeners 9 and the front transverse stiffener 11 also belong to the table base 5 in FIG. 1 shown in dotted lines.

Fig. 2 shows a partial front view of a table in which the arrangement of the guide rails 13 and the joint 15 with the longitudinal groove and the pin are better emphasized. In the region of the joint 15 with the longitudinal groove and the pin, there is also provided a pivot center 17, which will be described later in connection with the arrangement of their guide rails and in connection with the joint with the longitudinal groove and the pin.

As shown in FIG. 2, the transverse stiffener 11 is provided in front of the rear transverse stiffener

9. The rear cross brace 9 is connected to the rear legs 7 of the table base, while the front cross brace 11 is connected to the front legs 7 of the table base. On the bottom side of the arrangement of the water strips 13 there is provided one securing part 19, which will be explained in more detail later. Fig. 2 shows, in principle, local designs in particular with respect to the strips 13. The arrangement of the guide table front area with respect to the arrangement of the first example of the arrangement of the guide rail arrangement 13 is provided in the user's side.

In FIG. 3 is a section along line A-A in FIG. 1, bearing in mind that the arrangement of FIG. 3 is provided to both the right and left of the worktop 3. FIG. 3 emphasizes, in particular, the arrangement of the rear cross braces 9 and the front cross braces 11 on the table stand 5. In addition, the position of the pivot center 7, which is formed by the pin 21 of the joint 1.5 with the longitudinal groove and the pin, is shown.

In FIG. 4 is a section along line B-B in FIG. 1 and shows a side view of the worktop even in the left side edge of the worktop 3. Solid lines show the worktop 3 in its normal position, i.e. in the stowage plane on the table stand 5, while the dotted lines show the worktop 3 in its horizontally offset and angular set position. It should be noted that a quite suitable arrangement, such as on the left side of the worktop 3, is also provided on the right side of the worktop 3.

On the underside of the worktop there is an arrangement of guide rails on its front side

13, which is substantially wedge-shaped. The free wedge surface is provided with a transverse transverse fixed bearing of the stiffener 11 in a horizontal and angularly adjusted position arranged at an angle and with a horizontal plane of the acute angle α.

A longitudinal guide arrangement 31, which is formed by a longitudinal groove 29 and a pin 21, is provided at the front edge of the worktop 3 in its front region. This longitudinal groove 29 has a length sufficient to allow the pin 21 to move so far that the transverse stiffener 11 can fit into the transverse groove 25 of the guide rails 13 when the worktop 3 is adjusted.

In the normal position, the guide rails 1.3 are arranged with respect to the seating position of the user behind the transverse stiffener 11. With its rear end, the worktop 3 abuts the rear transverse support 9 of the table stand 5.

When the worktop 3, with its front end relative to the seating position of the user, is pushed by the user in the direction of the arrows shown in FIG.

horizontally to the front if the new surface 23 along the transverse parallel vertical elevation 11 varies until it fits into the transverse groove 25. The fraction plate 3 here pivots about the center of rotation 17, the pin 21 sliding in the longitudinal groove 29 a joint 15 with a longitudinal groove and a pin or a longitudinal guide arrangement 31.

This will lower the front end of the worktop 3 while its rear end will lift. Also shown in the drawing is the displaceability of the worktop 3. The angularly adjusted position of the worktop 3 in its original position is performed at an inclination angle θ with respect to the horizontal.

advantageously, this inclination angle θ is 8 ° in order to achieve the best ergonomic conditions for the user.

By briefly lifting the front end of the worktop 3 by the user, the transverse groove 25 is disengaged from the transverse reinforcement 11, which allows the worktop 3 to be slid back over the wedge surface 23 of the guide rail arrangement 13 again to its initial position.

In the second embodiment shown in FIG. 5, the guide rail arrangement 13 is arranged on the rear end and beneath the worktop 3 when viewed from the user's side. The configuration of the guide rails 13 is entirely identical to that of FIG. 4 and also the function corresponds to the function described above, except that the arrangement of the guide rails 13, with its transverse groove, fits into the rear cross brace 9 of the table base. The acute angle [alpha] and angle 1 [deg.] Of the slope are as large as described in the embodiment of FIG. 4. By adjusting the arrangement of the guide rails 13 at the rear end of the worktop, the table forces will be more evenly distributed, as the worktop 3 supports them as on the rear cross brace

9 and at the center of rotation 17, these support points being provided with each other substantially by 10 o in the embodiment according to FIG. 4th

In the two embodiments described so far, the guiding elements, i.e. the guide elements, were e.g. pin 21 and longitudinal groove

29, arranged in the upper side of the countertop side of the worktop 3 and the table base 5. In another embodiment of FIG. 6 to FIG. 8, the longitudinal groove and pivot joint 155 may be disposed in the direction of movement parallel to the two opposite lateral side edges of the worktop 3 therebetween and between the table base 5 on the corresponding underside of the worktop 3 and the table base in close proximity to the front side edges .

for this purpose, the joint 15 comprises a longitudinal groove and a pin of opposing guide elements 31 and has one guide element 31 of the pin 21 and a guide element 33 of the longitudinal groove 29.

33;

the second, relevant to him

The guide elements 31a are therefore arranged parallel to each other and are in the vicinity of the corresponding front side edges of the worktop 3 or the table base 5 on their corresponding underside. In this case, the pin 21 engages in the longitudinal groove 29 in the guide element 33, as can be seen in particular from FIG. 8th

In the modified example, FIG.

the longitudinal groove 29 is provided in the guiding element 31 and the cap is provided in the guiding element 33, that is to say precisely inverted with respect to the exemplary embodiment shown

The bottom view of FIG. 8, which is a section along the line C-C of FIG. 7 shows an exemplary embodiment in which the guide element 31 is mounted on a base 100 and the guide element 33 is mounted on a worktop that is joined by the plates 3.

33, 16th row, the transverse groove of the guide rails engages either in the rear transverse reinforcement 11 of the table base or qo of the transverse reinforcement i of the base according to the embodiments described above.

The length of the groove is of such dimensions that the pin 2 mi -H can sufficiently follow the sliding movement of the worktop 3.

According to the invention, therefore, a table 1 with a movable worktop is formed and its control does not require any space, while being parallel and vertically adjustable relative to its bearing plane on the table base 5.
