Description

[0001] The invention relates to a table frame for holding a tabletop.

[0002] Table frames are known in many different designs and in all conceivable sizes and heights, whereby those with corner legs, DE 20 2006 006 793 U1, can be equipped with profile-like table frame components and cross and transverse connectors for this purpose, and those without corner legs have central bases which are equipped with support feet extending from them to increase stability.

[0003] Such support feet are often either not very stable or so massive that the table frames equipped with them look rather flimsy.

[0004] A table frame is known – Artek, Helsinki, Finland: Artek. Website archived 12.05.2015 (according to the Internet Archive, San Francisco, CA, USA) URL: https: / / web.archive.org / web / 20150512074351 / https: / / www.artek.fi (accessed 05.12.2019) - with a one-piece, strip-shaped metal support leg, the upper ends of which terminate parallel under a tabletop and are fixed there, making this support leg disproportionately large and therefore very uneconomical and bulky.

[0005] Another well-known table frame – Leuwico GmbH, Wiesenfeld: iMOVE-F: This office furniture combines sophisticated design with perfect ergonomics. Website archived May 3, 2015 (according to the Internet Archive, San Francisco, CA, USA), URL: https: / / web.archive.org / web / 20150503111158 / http: / / www.leuwico.com / bueromoebel / buero_moebel / bueromoebel_ausstellung / imove_bueromoebel / imove_f_buero_moebel / bueromoebel_einrichtungsbeispiele / index.html (accessed December 5, 2019) – also features a one-piece support leg, which, however, is widely spaced and surrounds a plinth, matching the height of the table frame and thus being considerably larger than the plinth itself.

[0006] The object of the invention is to provide a table frame that is visually appealing, not large or bulky, and ensures maximum stability despite small external dimensions.

[0007] This problem is solved by a table frame having the features of independent claims 1, 2 and 3. Advantageous embodiments are the subject of the dependent claims.

[0008] The solution to this problem is achieved in particular by the fact that the table frame for receiving a tabletop has at least one one-piece or multi-piece base and at least one support foot for this base, wherein this support foot consists of at least one separate upper beam and at least one separate lower beam, and both beams are connected to each other and together they partially or completely encircle a lower part of the base of a table frame.

[0009] The support foot or lower beam and parts of the upper beam extend straight, at an angle, or curved perpendicular to the vertical plane of the base. Both the upper and lower beams have end foot sections arranged parallel to one another, and the upper beam has support sections that rest against the base on both sides, thus ensuring stable support for the support foot. If the support sections consist of multiple parts, they can be connected by force-fit, form-fit, and / or material-fit connections, or, in particular, they can be designed with detents at their upper edges so that they can be positively locked into corresponding detent grooves on the base.

[0010] This wrapping of a lower part of a table frame base, as well as the connection with the support beam, results in a mechanically very resilient construction that can safely support even tall, solid tables without the risk of being destroyed under excessive load.

[0011] According to the invention, a one-piece top beam can be designed as an inverted U-shaped profile, from the free lower ends of which lateral foot sections extend. These foot sections can be connected to corresponding foot sections of the bottom beam to form a closed linear structure. They are screwed together, in particular, from below through the foot section of the bottom beam to remain invisible from above. The foot sections can be arranged straight or at an angle to the free ends of the U-profile, or they can run in an arc. Alternatively, the foot sections could be bent or folded vertically upwards in the middle if this is visually desired.

[0012] According to another solution according to the invention, with a multi-part upper beam made of two L-profiles with their backs facing each other towards the base, the lower legs of the upper beam form the foot sections, which are connected to the foot sections of the lower beam, and the vertical legs of the upper beam form support sections, which are connected to each other through the base via a mechanical coupling element, so that here too a virtually closed linear structure of the support foot is created and forces from one side of the support foot can be reliably transferred to the other side of the support foot, with the foot sections of the upper beam being screwed to those of the lower beam.

[0013] In a further solution according to the invention with a multi-part upper beam made of two L-profiles facing each other with their backs towards the base, these are equipped at their upper ends with engagements directed towards each other and which are formed downwards again shortly before mutual contact, just as the base is equipped with central recesses in this area, so that the engagements can engage in the central recesses, whereby here too, when the foot sections of the lower beam and the upper beams are connected to each other and the upper ends of the support sections of the two L-profiles of the upper beam are locked in a quasi-positive locking manner, a mutual force transfer takes place.

[0014] In the case of a column-shaped base, it is advantageous to provide an additional support beam at an angle to the foot section of a support leg, which together with the support leg forms a support cross, so that the stability of tall column-shaped table frames can also be ensured.

[0015] The support feet according to the invention also serve to enable the equipping of several table frames so that they can be arranged under a common tabletop, thereby further increasing the variability of the inventive table frame.

[0016] According to a particularly preferred embodiment of the subject matter of the invention, the support foot can also be arranged on both free sides of the T-crossbeam in the case of a base lower part of a base which consists of a T-shaped plate in a side view, wherein any base upper part can be placed on the upright T-beam, which can also be T-shaped in a side view, wherein its crossbeam can form part of the bearing surface of the table top.

[0017] To increase the possibilities for visual variation, the crossbeam of the base can be covered with panels / decorative panels on both sides, just as the top of the base can be provided with further decorative panels on both sides, and decorative inlays can also be provided on the visible end faces of the crossbeam between the decorative panels.

[0018] Some embodiments of the invention are described in more detail below with reference to the drawings. They show: Fig. 1 a first support leg in a side view, Fig. 2 a second support leg in a side view, Fig. 3 a third support leg in a side view, Fig. 4. A first table frame in a front view, Fig. 5 a second table frame in a front view, Fig. 6 a third table frame in a front view, Fig. 7 a fourth table frame in a front view, Fig. 8 a fifth table frame in an exploded view, Fig. 9 a decorative panel for a fifth table frame, and Fig. 10 a fifth table frame in a top view.

[0019] The table frame 1-6 for receiving a tabletop 7-10 has a multi-part base 11-17, which is equipped with at least one support leg 18-22. The bases 11-17 are each assembled from several components, but could also be formed in one piece and then be provided with the corresponding longitudinal recesses from above for attaching the support legs 18-22.

[0020] The depicted plinths 11-15, as they are in the Fig. 4, Fig. 5, Fig. 6 to Fig. The table bases shown in Figure 7 are each composed of plate-shaped or solid components extending from the floor to the underside of the tabletop 7-10, with plate pieces inserted between them, under the support legs 18-21. The individual components are joined together using wood glue. The base 16, 17, on the other hand, consists of a plate with an inverted T-shaped cross-section, such as a plywood panel as the lower part of the base 16, and an upper part of the base 17, which is box-shaped and can be placed over the vertical T-beam of the lower part of the base. The lower part of the base 16 and the upper part of the base 17 can each be fitted with decorative panels 40, allowing the visual design of the table frame to be changed quickly and easily.The decorative panels 40 do not necessarily have to be rectangular, but can also be triangular, pentagonal or polygonal, as well as round, oval or have any other contour, just as the decorative panels of the upper part of the base 17 can also have an additional three-dimensional design. Fig. Figure 10 shows a top view of a lower part of the base 16 without the upper part of the base 17 attached, but with two support feet 22 arranged on the lower part of the base 16.

[0021] A support leg 18, as used in Fig. Figure 1 shows a lower beam 26 and an upper beam 23, which is approximately inverted in the shape of a U-profile and has horizontally extending foot sections 27 at the ends of the legs, which are screwed to the foot sections 28 of the lower beam 26 from below, via connecting means 32 designed as screws, so that the part of the base 11 enclosed inside the U-profile is surrounded on all sides without play.

[0022] With a support leg 19, as in the Fig. As shown in Figure 2, the upper beam 24 is formed in two parts and consists of two L-shaped components, the lower sections of which form the foot sections 27, which in turn are screwed to the foot sections 28 of the lower beam 26. In the upper areas of the vertical sections of the upper beam, it is formed with two horizontal sections that are shaped downwards approximately parallel to the central axis through the base 11, so that they form engagements 35 that can engage in a central recess 36 in the base 11.

[0023] A support foot 20, as shown in Fig. 3, also has such L-profile-shaped components of the upper beam 25, which, however, are connected to each other via a coupling element 34, so that all acting forces can be transferred to the other components via the coupling element 34, as well as via the positive locking of the engagements 35 in the central recess 36 or the one-piece upper beam 23.

[0024] As in the Fig. 4 and Fig. As shown in Figure 5, table frames 1-3 can be produced in different heights, as well as in Fig. 6 shown, in different widths or, as in Fig. Figure 7 shows how to assemble several table frames 4.5 under a large tabletop 10 to form a large table.
