Description

table construction

Field of application of the invention

The present invention relates to a table construction with a frame, at least one table top sitting thereon and feet detachably mounted on the frame, the frame and the feet being made of a square hollow profile. The subject matter is the expandability of the table surface, the foot attachment and the additional equipment of the table.

PRIOR ART A modular support frame system for a table is known from DE 102 02 194 A1. Longitudinal and transverse frames are connected to one another in a non-positive and positive manner by means of a fastening means. The applicant's German utility model 202 16 254 U1 discloses a table construction with a frame, a table top seated thereon and feet detachably attached to the frame, the frame and the feet at least partially consisting of a square hollow profile. The frame has a rectangular layout and has a front strut, a rear strut opposite this and two side struts. In each case one foot is arranged in each inner corner area formed by the frame and here lies with two adjacent surfaces on the inner surfaces of the struts which converge towards one another. There is a recess in the table top that allows access to a socket insert mounted under the table top. The frame can be enlarged by identical extension of the two opposite side struts so that the area covered by the frame expands to a multiple. Here, the area outlined by the frame is doubled when it is doubled, by inserting a first central strut into the horizontal plane spanned by the frame. When tripling, by additionally inserting a second central strut in the horizontal plane spanned by the frame, the second central strut attaches to the first central strut in a T-shape. OBJECT OF THE INVENTION The object of the invention is to propose a further developed table construction which can be expanded modularly as a modular system. It is important to limit the number of different parts required and to create efficient conditions for assembly. Even large combinations of tables must be characterized by high stability and resilience. According to modern requirements, the table should be equipped with superstructures and substructures, have electrification and make office work easier.

Overview of the invention

The table construction comprises a frame with at least four base struts, which form at least one table field and meet in pairs in the corner regions of the frame and are connected to one another by means of connectors. The feet are detachably attached to the frame. At least one table top is placed on the frame. The connectors are formed by corner angles, which consist of two side legs arranged at right angles to one another, which receive the pushed-on ends of the base struts. At the corner angles, the upper ends of the feet supporting the frame are also attached.

The following features relate to special embodiments of the invention: To extend the frame, bridge pieces are provided, by means of which the base struts can be connected to one another in pairs and arranged on a line. Furthermore, inner struts are provided which are attached to the base struts or on the one hand to a further inner strut by means of docking parts within the frame formed by the base struts.

In addition to the one table field, the following table combinations in particular can be set up: a) two table fields lined up on the narrow side, resulting in an oblong rectangular work surface; b) two table fields lined up alongside one another, from which a square table worktop results; c) two table fields lined up alongside one another and a narrow extension field attached to it on the narrow side, quasi T-shaped, resulting in a square work surface; d) two table fields lined up alongside one another and a table field attached to it on the narrow side, quasi T-shaped, resulting in a rectangular work surface; e) two table fields lined up alongside one another and two further table fields in turn attached to one another on the longitudinal side, resulting in a rectangular work surface; f) two table fields lined up alongside one another and two further table fields in turn attached to one another on the longitudinal side, and in each case on the outside a narrow approach field, quasi T-shaped, which results in a rectangular work surface; g) two table fields lined up alongside one another and two further table fields in turn attached to one another on the longitudinal side, and in each case one table field attached on the narrow side, quasi T-shaped, resulting in a rectangular work surface; h) two L-shaped table fields or a table field and an L-shaped attachment field attached to it; or i) three Z-shaped table fields or a table field, an L-shaped intermediate field attached to it and an L-shaped table field attached to it, which also results in a Z-shaped table combination.

A base strut can be designed as a short longitudinal strut, cross strut, long longitudinal strut or short strut. It is preferably: a) the length of the short longitudinal strut is twice the length of the cross strut; b) the length of the long strut, the length of the short strut plus the length of the cross strut; and c) the length of the short strut is half the length of the cross strut; and d) the length of the table top approximately the length of the short longitudinal strut and the width of the table top corresponds approximately to the length of the cross strut. A plate segment is provided to be placed on the table frame as a covering of an intermediate field or an attachment field, the width of the plate segment corresponding approximately to the length of the short strut and the length of the plate segment approximately corresponding to the length of the short longitudinal strut.

An inner strut can be designed as a long inner strut or a short inner strut, wherein: a) the length of the long inner strut corresponds to the length of the short longitudinal strut; b) the length of the short inner strut corresponds to half the length of the cross strut; and c) the base struts consist of a square hollow profile with a rectangular cross section, while the inner struts have a square cross section.

Box attachments are provided for installation on the work surface, which can preferably be detachably attached by means of adapter plates fastened under the box attachment and on the work surface and holding plates complementary thereto. Desk containers and base cabinets are designed to support the frame. There is a cutout in the table top for cable routing, and a cable network can be arranged under the work surface, which is advantageously detachably attached at least on one side. A socket unit, which is installed in a socket holder or a combination holder, is accessible via the cutout in the table top, the latter also serving to hold a screen rising vertically from the work surface.

The bridge piece comprises a central part, on each of which a flank part is attached, which is intended for pushing on the ends of the base struts. The docking part consists of a base and a shaft attached to it, wherein the docking part can be fastened with the base directly to the frame or to the middle part of the bridge piece.

The ends of the inner struts are for attachment to the docking part on it Shaft pushed on. The ends of the base struts and the inner struts are mitered. A support leg connected to the docking part can be mounted below a docking part built into the frame. The base of the docking part is screwed onto the middle part of the bridge piece. The end of the inner strut on the shaft of the docking part is attached by means of a wedge screw connection. The upper end of the foot is screwed to the corner bracket through the pushed-on ends of the base struts. There is a corner nose on the corner bracket, which positively engages in a locking slot at the upper end of the attached foot.

embodiment

The detailed description of an exemplary embodiment with variants for the table construction according to the invention is given below with the aid of the accompanying drawings.

The following definition applies to the entire further description. If reference numerals are included in a figure for the sake of clarity in the drawing, but are not explained in the directly associated description text, reference is made to their mention in the previous description of the figures. In the interest of clarity, the repeated designation of construction parts in the following figures mostly omitted, provided that it can be clearly seen in the drawing that these are "recurring" components.

Figures 1A to 1E Due to its modular structure, the table construction allows the creation of extended and variedly configured table combinations within a modular system with a correspondingly varied overall work surface. In the simplest embodiment (see FIG. 1A), the table with a table top 1 comprises a table field T1, the table top 1 resting on a frame 2 which is supported by four feet 3 arranged at the corners. In the table top 1, a recess 10 is provided for the supply of cables. An elongated work surface is created with a table combination with two table fields T1, T2 assembled on the narrow sides (see FIG. 1B). If two table fields T1, T2 are joined together on the long sides, a more square work surface results, the cutouts 10 abutting against one another (see FIG. 1C). A larger rectangular work surface results from the combination with two table fields T1, T2 put together on the long sides and a third table field T3 attached transversely thereto (see FIG. 1D). Since the dimensions of the table tops 1 are chosen so that the length is twice the width, the narrow sides of the field T3 are flush with the long sides of the fields T1.T2. A further enlarged rectangular work surface is created by combining two table tops T1-T4 put together (see Figure 1E).

Figures 1 F and 1 G

This pair of figures shows a box attachment 4 which is intended to be placed on the work surface formed by the table (see FIGS. 1K to 1P). The box top 4 has a partition 40, e.g. two adjacent open compartments, and is clad from behind with a rear wall 42.

Figure 1H

A desk container 45 with a drawer partition 46 can also be provided as a supporting substructure under the frame 2, so that on this table side then the arrangement of supporting feet 3 is superfluous (see Figures 1 K and 10).

Figure U Instead of the desk container 45, a base cabinet 48, which consists of a body 480 and various subdivisions 49 for accommodating trays 481 or pull-outs 483, can be considered as the substructure under a table combination with at least two table fields T1, T2. The base cabinet 48 is preferably open to the user side or provided with sliding doors 482 on the front. The use of the base cabinet 48 is illustrated in FIGS. 1K and 10.

Figures 1K to 1P

A typical equipment for a table with a table field T1 is a permanently mounted desk container 45 as a supporting substructure and a box attachment 4 is to be provided above the table top 1 and the desk container 45 (see FIG. 1K). Two box attachments 4 placed next to one another can be placed on an attachment area A1 opposite the user (see FIG. 1L) or on an attachment area A1 to the side of two table areas T1, T2 (see FIG. 1M). Another typical configuration is the arrangement of two supporting base cabinets 48 below two and the simultaneous installation of two box attachments 4 above the base cabinets 48 (see FIG. 1N). With a work surface consisting of four table fields T1-T4 put together in a rectangle, it is advisable to install desk containers 45 placed on both outer flanks and box attachments 4 arranged above them (see FIG. 10). In the case of a table combination in a Z-shaped offset arrangement with two table fields T1.T2, central base cabinets 48 and box attachments 4 in above can be installed (see FIG. 1P).

Figures 2A to 3

This sequence of figures illustrates the equipment of differently configured work surfaces with a screen 5 for the user. Such a screen 5 represents a delimitation of the work surface, thus preventing this Falling things and at the same time serves to attach notes or to hold small items in suitable holders. In the case of a table with a table field T1, the screen 5 is attached to the user on the long side of the table (see FIG. 2A). In the case of two table fields T1, T2 arranged quasi-square, the common screen 5 is provided in the area of the adjacent table fields T1.T2 (see FIG. 2B). In the three-way combination with the table fields T1-T3 there are two screens 5, which are each mounted on the adjoining table fields T1, T2; T3, T1 / T2 (see FIG. 2C). In the Z-shaped offset table combination with two table fields T1.T2 and an inserted intermediate field Z1, a separate screen 5 belongs to each table field T1, T2, the intermediate field Z1 being covered with a plate segment 100 (see FIG. 3).

Figures 4A to 5H This sequence of figures shows floor plans of the simplest table with only one table field T1 up to combinations of six with six table fields T1-T6 and Z-shaped configurations.

The base frame of a table with only one table field T1 (see FIG. 4A) has a frame 2, which is formed from two short longitudinal struts 20 arranged parallel to one another at a distance and two cross struts 21 closing the frame 2. In the corner regions of the frame 2, the short longitudinal struts 20 and the cross struts 21 are connected to one another and, at the same time, the feet 3 are arranged. The short longitudinal struts 20 have a length of 1800 mm, for example, and the cross struts 21 have a length of 900 mm. In the case of the table combination with two table fields T1, T2 put together on the narrow sides, that is to say in the longitudinal direction adjacent to one another, the frame 2 consists of two short longitudinal struts 20 which are connected in alignment with one another, two transverse struts 21 closing the frame 2 on the side flanks and a short inner strut 24 of, for example, 900 mm in length, as a transition between the two table fields T1.T2 (see FIG. 4B). Between two table fields T1, T2 that complement each other to form a square, there is a long inner strut 23 of, for example, 1800 mm in length in the transition (see FIG. 4C). In the basically T-shaped table combination with the Table fields T1-73 use long longitudinal struts 22 with, for example, 2700 mm, short longitudinal struts 20 and two long inner struts 23 inserted in a T-shape within frame 2 (see FIG. 4D).

The frame 2 of the four-person table combination formed in the rectangle with the table fields T1-74 is formed on the outside by six short longitudinal struts 20, two pairs of two longitudinal struts 20 being assembled, while three long inner struts 23 are arranged in a cross (see FIG. 4E ). The table combination with two table fields T1.72 set up in a square and a common attachment field A1 has a frame made up of two short and long longitudinal struts 20, 22 and two long inner struts 23 which are arranged in the T-profile (see FIG. 4F). The frames 2 of more complex table combinations are composed on the outside of corresponding struts 20, 22, 23, it also being possible to connect short longitudinal struts 20 and parts otherwise used as cross struts 21 to form elongated longitudinal frame parts (see FIGS. 4G and 4H).

With the L- or Z-shaped table combinations with the table fields T1, 72 (see Figures 5A and 5B), or the fields 71.A1 (see Figures 5C and 5D), or the fields 71.Z1.72 (see Figures 5E and 5F), or the table fields T1-73 (see Figures 5G and 5H), come for the construction of the respective frame 2 short and long longitudinal struts 20, 22, cross struts 21 and for the narrow sides of the free ends of the attachment fields A1 Short struts 25 for use. Short longitudinal struts 20 are located next to cross struts 21 in the transitions between the fields.

Figures 6A and 6B

The frame 2 for the table field T1 (see FIG. 6A) is composed of two short longitudinal struts 20 arranged parallel to one another at a distance and two cross struts 21 closing the frame 2. The ends of the struts formed from a square hollow profile are in principle provided with a miter cut. To cover the table field T1 there is a correspondingly cut table top 1 with the recess 10 in the middle on a longitudinal edge. To the Covering the edge of the recess 10, an edge cover 11, for example a rubber profile, is provided. For the attachment of the table top 1 serve plate holder 29, which are used distributed on the inside of the struts 20,21. By means of screws 290 inserted from below through the plate holder 29, which engage into the table top 1 from the underside, the table top 1, which otherwise rests on the assembled frame 2, is held. In the case of the attachment field A1 (see FIG. 6B), two short struts are used instead of the cross struts 21

25 used for the frame 2, and an undamaged plate segment 100 is provided as a cover.

Figures 7A and 7B

To form a frame 2 with a table field T1 and an attachment field A1, two long longitudinal struts 22 are used, which are parallel to each other. The boundary between the fields 71.A1 forms an H-shaped long inner strut 23 inserted between the longitudinal struts 22, which is fastened at its two ends with a docking part 26 to the inner flanks of the two longitudinal struts 22. The inner strut 23 is preferably a hollow profile of square cross-section, in the ends of which the shaft of the respective docking part

26 is pushed in. The bases of the docking parts 26 are screwed onto the inner flanks of the longitudinal struts 22. The table top 1 and the plate segment 100 are intended to cover the table field T1 and the approach field A1. If you want to install box attachments 4 above the attachment area A1, adapter plates 41 are attached to the attachment area A1, while complementary holding plates 410 are fastened under the case attachments 4, so that the box attachments 4 can be detachably snapped onto the adapter plates 41 (see FIG. 7B).

FIG. 8A The ends of the short longitudinal struts 20 and cross struts 21 which converge in the corners are connected to one another by means of corner angles 27. At the corner angles 27, the feet 3 are fastened with their top

Head plates 32 mounted. At the bottom the feet 3 are provided with a slider part 30 and a sleeve part 31 which is inserted in the foot end and which swellable slider part 30 receives. The feet 3 are preferably made of a hollow section with a square cross section. For the corner bracket 27 there is a bracket-shaped flank cover 278 created for aesthetic purposes, which can be snapped onto the corner bracket 27 from the outside.

Figure 8B

For a table combination with two table fields T1.72 formed in a square, four short longitudinal struts 20 are used to create the frame 2, in the middle of which a long inner strut 23 is inserted, which is again fastened with docking parts 26 installed on both sides. Corresponding to the doubled work surface, two table tops 1 serve for covering, the recesses 10 of which are directed towards one another.

FIG. 8C For a table combination with three table fields T1-73 formed in a square, two short longitudinal struts 20 and two long longitudinal struts 22 are required to create the frame 2. Within the frame 2 stretched in this way, a first long inner strut 23 and T-shaped is centered in the longitudinal direction a second long inner strut 23 is used for this. The inner strut 23 is fastened to the outer frame and the two inner struts 23 are fastened to one another by means of docking parts 26. To cover the expanded work surface, three table tops 1 are now used, which are in principle joined to one another in a T-shape.

Figures 9A to 9E

To fasten the foot 3 in the corners of the frame 2, in a first variant, a head plate 32 is firmly attached to the upper foot end, for example welded on. The top plate 32 has at the top a surface formed as a right-angled triangle, which initially runs from the outside in a horizontal section to the right angle in order to pass into a section with a slight downward slope in the region of the depressions 332. The surface has a cutout 321 in the right-angled corner region. At the outer ends of the sides of the triangle, which enclose the right angle between them, there are bends 320 provided, which are angled vertically downward and provided with a screw hole 323 and extend inwards to the vicinity of the depressions 322. The head plate 32 is placed on the open upper end face of the foot 3 and projects with the downwardly inclined section of the upper surface into the cavity of the foot 3. The outer edges of the downwardly inclined section come to rest on the inner surfaces of the foot 3, so that the head plate 32 is secured against horizontal displacements. In the welded-in state, the cutout 321 in the head plate 32 faces a locking slot 34 at the upper end of the foot 3.

For leveling the foot 3 is provided with a slider 30 which is received by a sleeve part 31 which is inserted in the lower end of the foot 3. Slider 30 and sleeve part 31 have mutually complementary threads, so that the slider 30 can be adjusted by turning.

Figures 9F to 11E

In a second variant for the attachment of the foot 3, the head plate 32 is replaced by an angle 35 which protrude through through slots 33 in the upper end of the foot 3 into the interior thereof. The angle 35 is partially movable, has a screw hole and an inner bend 230, which stabilizes the position of the angle 35 in the screwed position.

A corner bracket 27 comprises two side legs 270 arranged at right angles to one another, of flat rectangular cross section. At the free ends of the side legs 270, the outer surfaces are chamfered, so that tapered ends result. A corner projection 271 protrudes inwards from the corner area where the two side legs 270 meet. The side legs 270 have an internally threaded bore 272 arranged near their free ends. The ends of the longitudinal struts 20, 22 and the cross struts 21 are each cut to a 45 ° miter. If, for example, two struts 20, 21 are to be connected to one another by a corner bracket 27, the short longitudinal strut 20 and the cross strut 21 are pushed onto the respective side legs 270 until the mitres meet one another, each with an internal thread bore 272 in the side legs 270 with one of the screw holes 201 in the struts 20,21 to cover.

A rectangular end cut 200 is provided on the vertically arranged inward-facing surfaces of the cross strut 21 and the short longitudinal strut 20, which together when the struts 20, 21 are pushed on form an opening in which the corner nose 271 is accommodated and through which the corner nose 271 of the corner bracket 27 protrudes outwards. In the first variant of the foot fastening (see FIGS. 11B to 11E), screws 39 are screwed through the bends 320 of the head plate 32 and the screw holes 201 in the struts 20, 21 into the internally threaded bores 272 at the corner bracket 27. In the second variant of the foot fastening (see FIGS. 9F to 9H), the screws 39 are screwed through the angles 35 and the screw holes 201 in the struts 20, 21 into the internally threaded holes 272 in the corner angle 27. In both cases, the corner nose 271 of the corner bracket 27 also engages in a form-locking manner in the locking slot 34 present at the upper end of the foot 3. The flank covers 278 are designed to cover the gap that remains between the outwardly facing surfaces of the struts 20, 21 pushed onto the corner bracket 27. The bracket-like flank cover 278 consists of an outer bar 2780, from each end of which a locking arm 2782, which is arranged perpendicular to the outer bar 278, projects. In the direction of the locking arms 2782, the outer bar 2780 merges into a narrower and shorter inner bar 2781. The locking arms 2782 and the inner bar 2781 are concealed at the corner bracket 27.

The bridge piece 28 is made in one piece from a central part 280 and on both sides of the flank parts 285 which are attached to it. A cylindrical spigot, which is provided with a threaded bore 286, rises vertically from the bottom of each flank part 285. From the bottom of the central part 280 protrude pins arranged in a square, which also each have a threaded bore 282. On the inside, the middle part 280 has an angular molded connection 281 directed towards the two flank parts 285. The bridge piece 28 is also advantageously a die-cast part.

Figure 12E

To connect the bridge piece 28 to the docking part 26, the screw holes 261 in the base 260 of the docking part 26 are brought into alignment with the threaded bores 282 in the middle part of the bridge piece 280 on the side of the molded connection 281 and the screws 262 can now be inserted. In principle, a T-piece is created when connected.

Figures 13A and 13B

The bridge piece 28 serves to connect, for example, two short longitudinal struts 20 (for an example, see the table combination according to FIG. 4E), which are pushed onto the flank parts 285 of the bridge piece 28 and then screwed together. The form connection 281 on the central part 280 of the bridge piece 28 has a contour which is complementary to the end cut 200 in the short longitudinal strut 20, so that the longitudinal strut 20 is pushed onto the flank part 285 in a form-fitting manner, a screw hole 201 in the longitudinal strut 20 with the threaded bore 286 of the flank part 285 comes to cover. One through the screw hole 201 guided screw 289, which engages in the threaded bore 286 on the flank part 285, secures the longitudinal strut 20 pushed onto the bridge piece 28. A strut 20 can be fixed in the same way on the remaining flank part 285. The struts 20 pushed between the miter cuts on both of the bridge piece 28 are covered with a complementarily contoured clip 288 to be snapped on.

Figures 14A to 15B

This sequence of figures illustrates the fastening of an inner strut 23 and a support foot 3 'to the docking part 26. The inner strut 23 has a wedge hole 231 on the two vertical surfaces, which are aligned with one another, and is pushed onto the docking part 26 in such a way that the wedge holes 231 come to rest in the inner strut 23 in front of the wedge passage 266 in the docking part 26. Now the wedge 267 is inserted from the outside through the wedge hole 231 on the one vertical surface of the inner strut 23 into the wedge passage 266 in the docking part 26. From the other vertical surface of the inner strut 23, the washer 2690 and the wedge screw 269 are inserted through the wedge hole 231 on this side and screwed together with the wedge 267.

The support foot 3 'has a U-shaped cutout 37 and a vertically running threaded hole 38 accessible from above at the upper end on two opposite sides. In its cutout 37, the vertical support leg 3 ″ accommodates the horizontal inner strut 23. A vertically continuous screw hole 230 is present in the horizontal surfaces of the inner strut 23. For mounting the support leg 3 ′, the inner strut 23 is placed in such a way that the screw holes 230 and the threaded hole 38 of the foot 3 come to lie one on top of the other 3. A screw 389 supplied from above through the screw hole 230 engages in the threaded hole 38 of the supporting foot 3 'and thus secures it. Depending on the constellation 28 different struts 20-25 can be on the bridge piece meet. FIGS. 16A and 16B.
