DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0045] FIG. 1 shows a table frame 10. The table frame 10 has a longitudinal beam 12. A transverse beam 14 of the table frame 10 is arranged at both ends of the longitudinal beam 12. Further, a table leg 16 of the table frame 10 is arranged at each end of the longitudinal beam 12. The table legs 16 each have a housing part 18. Further, the table legs 16 may each have a column portion 20 and a leg portion 22. The table leg 16 on the left in FIG. 1 is shown during its installation. The table leg 16 on the right in FIG. 1 and the associated transverse beam 14 are shown in an assembled state. In the assembled state, the longitudinal beam 12 and the two transverse beams 16 form a contact surface 24 for a tabletop 26 of a table 28, compare FIG. 2.

[0046] FIGS. 3, 4 and 5 show detailed views of the assembled table frame 10 or table 28 in the area where the longitudinal beam 12 is connected to one of the transverse beams 14 and one of the table legs 16. FIGS. 6 and 7 show detailed views of the table frame 10 during installation of one of the transverse beams 14 and one of the table legs 16 to the longitudinal beam 12.

[0047] The present longitudinal beam 12 has two side walls 30. In particular, the longitudinal beam 12 can be U-shaped in cross-section, see FIG. 7. The longitudinal beam 12 has two longitudinal beam protrusions 32. The longitudinal beam protrusions 32 each project from one of the side walls 30, compare in particular FIGS. 3 and 6. Transverse to a longitudinal direction of the longitudinal beam 12, the longitudinal beam protrusions 32 are spaced apart, compare FIG. 4. The longitudinal beam protrusions 32 may be formed integrally with the respective side walls 30. In particular, the longitudinal beam 12 can be formed in one piece as a whole.

[0048] The housing part 18 has two housing protrusions 34. The housing part 18 may be box-shaped with two longitudinal walls 36, compare in particular FIGS. 6 and 7. The housing protrusions 34 may be disposed in extension of the longitudinal walls 36 (in other words, flush with the longitudinal walls 36) on the housing part 18. The housing protrusions 34 and the associated longitudinal wall 36 may each be integrally formed with one another.

[0049] The housing parts 18 can each contain a motor, not shown in more detail, with electrical connections 37 (compare FIG. 7) for adjusting the length of the respective table leg 16. The table legs 16 can be telescopic for this purpose.

[0050] The transverse beam 14 may have an end wall 38 and a top wall 40. The end wall 38 and the top wall 40 may extend at right angles to one another. The top wall 40 can contribute to form the contact surface 24 for the tabletop 26.

[0051] The top wall 40 of the transverse beam 14 may have two retaining recesses 42, compare FIGS. 3 and 6. Two retaining projections 44 of the longitudinal beam 12 can engage the retaining recesses 42. The retaining projections 44 may extend from the longitudinal beam 12, particularly its side walls 30, toward the contact surface 24 for the tabletop 26 (i.e., upward in the use position).

[0052] The end wall 38 of the transverse beam 14 has two recesses 46, see in particular FIG. 4. The recesses 46 may be formed as through-going recesses and may, for example, be punched or cut out of the transverse beam 14. Alternatively, the recesses 46 in the transverse beam 14 could be covered in some areas or completely and could, for example, be formed as indentations (not shown).

[0053] The recesses 46 are each bounded by two opposing edge portions 48a, 48b. The edge portions 48a, 48b are each formed in a straight line here. The edge portions 48a, 48b may bound the recesses 46 upwardly and downwardly (toward and away from the contact surface 24 for the tabletop 26, respectively). The two edge portions 48a, 48b of one of the recesses 46 are each arranged here one above the other in the vertical direction.

[0054] In an embodiment not shown in greater detail, the edge portions 48a, 48b could be laterally offset from one another (transverse to the longitudinal direction of the longitudinal beam 12). It is also conceivable that the edge portions each define separate recesses. The two edge portions could delimit a web portion of the transverse beam and, in particular, could be formed on free edges of the transverse beam (not shown in more detail).

[0055] To install the transverse beam 14 on the longitudinal beam 12, the longitudinal beam protrusions 32 can first be inserted into the recesses 46. For this purpose, the transverse beam 14 can be tilted about its axis relative to the longitudinal beam 12. Next, the transverse beam 14 can be rotated relative to the longitudinal beam 12 to its position shown in the figures, with the retaining projections 44 engaging the retaining recesses 42.

[0056] To fix the transverse beam 14 to the longitudinal beam 12, the housing protrusions 34 of the housing part 18 are inserted into the recesses 46 of the transverse beam 14 (compare in particular FIG. 6) and the table leg 16 with the housing part 18 is brought into its final position relative to the longitudinal beam 12 (compare in particular FIG. 3). In this final position or a mounted state, the longitudinal beam protrusions 32 and the housing protrusions 34 rest under preload against the opposing edge portions 48a, 48b of the transverse beam 14. Upon installation of the table leg 16 the housing protrusions 34 can be pressed against the lower edge portions 48b. The longitudinal beam protrusions 32 can be pressed against the upper edge portions 48a upon installation of the table leg 16. The housing protrusions 34 and the longitudinal beam protrusions 32 are therefore supported on the transverse beam 14 in opposite directions. This allows the transverse beam 14 to be held frictionally against the longitudinal beam 12 and the housing part 18.

[0057] For the installation of the table leg 16, it can be swiveled in relation to the longitudinal beam 12. Two pins 50 are arranged here on the housing part 18 (compare FIGS. 3, 6 and 7). The side walls 30 of the longitudinal beam 12 each have a curved slot 52. During installation of the table leg 16, the pins 50 are first inserted into open ends 54 of the slots 52. Hereto, the table leg 16 is held at an angle. The table leg 16, which is held at an angle, is then advanced along the slots 52 until the pins 50 rest against a respective end section 56 of the slots 52 and the housing protrusions 34 engage in the recesses 46 of the transverse beam 14. Now the table leg 16 is rotated around a pivot axis running through the two pins 50 while the pins 50 are in contact with the end sections 56 of the slots 52 until it reaches its final position.

[0058] The final position of the table leg 16 relative to the longitudinal beam 12 may be defined by a stop 58. Preferably, the stop 58 is established between the housing part 18 and the longitudinal beam 12. The stop 58 may be formed with a projection 60 and a return recess 62, compare FIGS. 3, 6 and 7. The projection 60 may be disposed on the housing part 18. The return recess 62 may be formed in the side wall 30 of the longitudinal beam 12. Here, the return recess 62 extends transversely to a longitudinal direction of the longitudinal beam 12. Due to the engagement of the projection 60 in the return recess 62, the table leg 16 is therefore also positively secured to the longitudinal beam 12 against displacement in the longitudinal direction of the latter, compare FIG. 3.

[0059] To hold the table leg 16 in the final position defined by the stop 58, the table leg 16 can be latched to the longitudinal beam 12. A latching element 64 can be rotatable relative to the longitudinal beam 12, compare FIG. 7. The latching element 64 can be a bracket. Alternatively, two separate and independently operable latching elements can be provided, which can be mounted opposite one another on the side walls 30 of the longitudinal beam 12 (not shown in more detail). Here, the latching element 64 is supported on the longitudinal beam 12 by a spring element 66, for example a spring wire. The housing part 18 of the table leg 16 may have setbacks 68. Latching tabs 70 of the latching element 64 are brought into rear engagement behind the setbacks 68 by the spring element 66 when the table leg 16 is in the final position. The latching element 64 with the latching tabs 70 then prevents the table leg 16 from being swiveled back.

[0060] To be able to swivel the table leg 16 back for disassembly, the latching can be released manually. For this purpose, a release lever 72 can cooperate with the latching element 64. By actuating the release lever 72, the latching element is rotated against the action of the spring element 66 in such a manner that the latching tabs 70 are guided out of the setbacks 68. The table leg 16 can then be rotated about the pivot axis (compare pin 50) while releasing the tension between the edge portions 48a, 48b and the longitudinal beam protrusions 32 and the housing protrusions 34 and guided out of the slots 52.
