DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0059] FIGS. 1 and 2 show a fitting 10. In FIG. 1, the fitting 10 is shown in a closed state. In FIG. 2, the fitting 10 is in an open state.

[0060] The fitting 10 has a first fitting part 12 and a second fitting part 14. The two fitting parts 12, 14 may be connected to each other via screws not shown in more detail here. The fitting parts 12, 14 can have edge sections for contact with a table top on the upper and lower sides, respectively.

[0061] A first clamping part 16 in the form of a cover 18 is displaceably guided on the first fitting part 12. In the closed state of the fitting 10 (compare FIG. 1), the first clamping part 16 is in a clamping position; in the open state of the fitting 10 (compare FIG. 2), the first clamping part 16 is in a release position.

[0062] The fitting 10 further comprises an actuating element 20. The actuating element 20 may comprise a protrusion 22 for deflecting the actuating element 20 with fingers of a hand. By actuating the actuating element 20, the first clamping part 16 can be brought into the clamping position or release position.

[0063] Individual parts of the fitting 10 are shown below in individual figures. Here show

[0064] FIG. 3: the cover 18 forming the first clamping part 16,

[0065] FIG. 4: the actuating element 20,

[0066] FIG. 5: the first fitting part 14,

[0067] FIG. 6: a bolt 24,

[0068] FIG. 7: a second clamping part 26 in the form of a clamping ring 28,

[0069] FIG. 8: the second fitting part 14.

[0070] In FIG. 9, the fitting 10 is shown in the closed state (compare FIG. 1) in a sectional view. FIG. 10 shows a further view of the first clamping part 16 formed by the cover 18.

[0071] FIG. 11 shows a table 30. The table 30 has a table top 32. The table 30 further comprises a table frame 34. The table frame 34 is formed here with two columns 36. The two columns 36 may extend in a generally straight line. The columns 36 extend parallel to each other. In the present embodiment, the columns 36 are oriented at an angle. In the illustrated embodiment of the table 30, a support leg 38 is pivotally hinged to each of the columns 36. In the unfolded state, the support legs 38 hold the columns 36 at the predefined inclination relative to the vertical. The two support legs 38 may be connected to each other by a cross brace 40.

[0072] The table top 32 is height-adjustable at the columns 36. Two fittings 10, 10′ are inserted in openings in the tabletop 32 for this purpose. The columns 36 extend through the fittings 10, 10′. The two fittings 10, 10′ of the table 30 are mirror symmetrical to each other. The individual parts shown in FIGS. 3 to 8 can be assembled in two different configurations to obtain the mirror symmetrical fittings 10, 10′. The assembly condition of the fitting 10 is the same as that of the fitting 10 shown in FIGS. 1, 2 and 9.

[0073] For use of the table 30, the table top 32 is clamped to the columns 36. For this purpose, the first and second clamping parts 16, 26 of the fittings 10, 10′ are each brought into the clamping position by means of the actuating elements 20. To adjust the height of the table top 32, the first and second clamping parts 16, 26 are each brought into the release position by means of the actuating elements 20. The table top 32 can then be tilted and moved along the columns 36. When the table top 32 is released, it is clamped again to the columns 36 via the fittings 10, 10′. In order to secure the set height, in particular against unintentional adjustment upon contact with the table top 32, the fittings 10, 10′ are closed again by means of the actuating elements 20.

[0074] The interaction of the individual parts of the fitting 10 or 10′ with each other and with the respectively assigned column 36 is described in detail below.

[0075] The first fitting part 12 has a first abutment section 42 for abutment against the column 36. The second fitting part 14 has a second abutment section 44 for abutment against the column 36. The abutment sections 42, 44 of the two fitting parts 12, 14 are designed to abut against the column 36 from opposite directions, compare in particular FIG. 9. When the table 30 is in use, the abutment sections 42, 44 contact the column 36 from the rear and the front, respectively. To adjust the height of the table top 32, the abutment sections 42, 44 are lifted off the column 36. The abutment sections 42, 44 may each include a friction lining 46a, 46b. The friction lining 46a, 46b may each be a rubber element. The friction linings 46a, 46b increase the friction between the abutment sections 42, 44 and the column 36.

[0076] The first and second fitting parts 12, 14 each have a bearing seat 48, 50 for rotatable mounting of the bolt 24, compare FIGS. 5 and 8. In the present case, a further bearing seat 48′, 50′ is provided in each case for mirror-inverted mounting of the bolt 24. In the first fitting part 12, the bearing seats 48, 48′ are formed by recesses connected to one another. In the second fitting part 14, the bearing seats 50, 50′ are formed by recesses separate from one another. For engagement in the bearing seat 48 of the first fitting part 12, radial wall sections 52 can be provided on the bolt 24, compare FIG. 6.

[0077] The actuating element 20 is rotationally coupled to the bolt 24. In other words, actuation of the actuating element 20 causes rotation of the bolt 24 about its bolt axis 25. The actuating element 20 (compare FIG. 4) has a non-rotationally symmetrical recess 54, which may be formed with two partial recesses, for engagement or penetration of the bolt 24. The bolt 24 has a terminal bolt portion 56 and an extension 58 offset from the bolt axis 25, compare FIG. 6. The extension 58 may protrude in the axial direction beyond the terminal bolt portion 56. In the assembled state, the terminal bolt portion 56 engages in the recess 54 of the actuating element 20; the extension 58 projects through the recess 54 (compare also FIG. 9).

[0078] For the sliding guidance of the cover 18 on the first fitting part 12, guiding devices 60a, 60b corresponding to one another are formed on the first fitting part 12 and the cover 18, compare FIGS. 5 and 10. The cover 18 can have a further friction lining 46c which abuts against the column 36 in the closed state of the fitting 10, i.e. when the first clamping part 16 formed by the cover 18 is in the clamping position, compare FIG. 9.

[0079] The first clamping part 16 has an elongated recess 62 which extends transversely to the direction of displacement, compare FIGS. 9 and 10. The eccentric extension 58 of the bolt 24 engages in the elongated recess 62. Thus, rotation of the bolt 24 causes movement of the first clamping part 16 between the clamping position and the release position.

[0080] In order to secure the closed state of the fitting 10, a locking mechanism is provided between the actuating element 20 and the cover 18. The cover 18 has a detent contour 64 (compare FIG. 10), which cooperates with a nose 66 of the actuating element 20 (compare FIG. 4). In the closed state of the fitting 10, the nose 66 of the actuating element 20 presses the first clamping part 16 against the column 36.

[0081] The clamping ring 28 forming the second clamping part 16 is slidably guided on the second fitting part 14. Guiding devices 68a, 68b corresponding to one another are formed for this purpose on the second fitting part 14 under the clamping ring 28, compare FIGS. 7 and 8. The clamping ring 28 may have a friction lining 46d for contact with the column 36.

[0082] The clamping ring 28 has two elongated holes 70, 70′ through which a second bolt portion 72 can be guided for engagement with the bearing seats 50 and 50′, respectively, in the second fitting part 14.

[0083] In order to move the second clamping part 26 (the clamping ring 28) between the release position and the clamping position during a rotation of the bolt 24, the second clamping part 26 and the bolt 24 cooperate via a toothing. A first toothed portion 74 is formed on the bolt 24 in the form of a gear segment. Two second toothed portions 76, 76′ in the form of toothed racks are formed on the second clamping part 26 (symmetrically with respect to a center plane). Depending on the assembled configuration of the fitting 10 or 10′, the first toothed portion 74 of the bolt 24 interacts with the second toothed portion 76 or 76′ of the second clamping part 26.

[0084] For assembly of the fitting 10 or 10′, the bolt 24 is inserted rotated accordingly. The engagement positions for the bolt 24 in the fitting parts 12, 14 (engagement in the bearing seats 48 and 50 or 48′ and 50′) as well as the passage through the clamping ring 28 (protruding through the elongated hole 70 or 70′) change correspondingly. The actuating element 20 is also placed on the bolt 24 rotated accordingly. Otherwise, there are no differences for the assembly of the fitting 10 or 10′.

[0085] FIG. 12 shows the table 30 in a folded state. The support legs 38 are folded up against the columns 36. The table top 32 is pulled off from the columns 36. The table top 32 can be hooked to the support legs 38 with the aid of hook elements 78. The hook elements 78 are presently formed on the second fitting parts 14, here moulded thereon.

[0086] In summary, the invention relates to a fitting for adjusting the height of a table top on a column and to a table with such a fitting. For use of the table, a table top is frictionally held to the column by means of the fitting. To change the height of the table top, the frictional engagement is released by tilting the table top relative to the column. To secure the table top at the set height, at least one clamping part is provided on the fitting. By means of an actuating element, the clamping part can be brought into contact with the column so that tilting of the table top relative to the column is not possible. To allow the height adjustment, the clamping part can be removed from the column by means of the actuating element so that tilting of the table top relative to the column is possible.
