Abstract

An office desk suited in particular for peripheral computer equipment consists of two side parts formed by columns provided with feet, a longitudinal beam detachably connected with the columns by connection elements establishing a form-locking connection, and of carrying arms for at least one table top mounted on the longitudinal beam. These components can be varied in many different ways and combined in the most different manners so that office desks optimally adapted in each case to the respective application can be realized with the same basic elements.

Description

The invention relates to an office table, in particular for computer peripheral devices, with a table frame consisting of two side parts and a longitudinal support connecting the side parts and a table top arranged between the side parts.

Office tables with this structure are known in many different forms. For example, such an office table is described and shown in DE-PS 32 07 177. It fulfills all requirements with regard to high stability and the possibility of adaptation to different working conditions thanks to a table top that is adjustable in height and inclination.

Modern office operations and in particular the increasing use of text and data processing with their variety of different peripheral devices, such as screens, mass storage devices and printers of different types, require a large number of office desks with different structures for their optimal use. For example, tables are often required for display devices with a keyboard, the table tops of which have sections lying at different heights, while tables for printers only have to offer small storage spaces, but should, for example, have a possibility of attaching baskets. Although there are special embodiments of tables and frames for all of these purposes, which fulfill the respective purpose, the manufacture of such special designs is uneconomical.

The invention is therefore based on the object of designing an office table of the type mentioned at the outset in such a way that it can be optimally adapted to many uses, either by modifications made by the manufacturer or by measures which the user can take himself.

This object is achieved according to the invention in that the side parts are formed by columns provided with feet, that the columns have connecting links, with which corresponding connecting members are positively engaged on the longitudinal member releasably connected to the side parts, and that support arms for the table top are attached to the longitudinal member.

The office table according to the invention therefore does not consist of a uniform frame with an adapted table top, but is constructed from several parts which are detachably connected to one another and by the exchange of which the most varied table configurations can be created. Depending on whether the side parts are provided with symmetrical or asymmetrical feet, symmetrical or asymmetrical table structures can be created. Here, symmetrical table structures are of particular importance, that is to say an office table in which the feet are arranged essentially symmetrically with respect to the columns and the longitudinal beam is provided with support arms on its two outer sides. In addition to the fact that a common, continuous table top can be arranged in a conventional manner on the support arms, this embodiment of the invention offers the possibility of providing the table on both sides with table tops of different design and / or structure in order to optimally adapt to specific applications to find. A table top can also be attached on one side, while any additional devices are attached on the other side of the side member. In particular, the support arms can be arranged at different heights, so that the table has sections of the table top at different heights, as is expedient for many computer peripheral devices. In a preferred embodiment of the invention, the longitudinal beam has hooks at its ends, which engage in corresponding recesses on the columns. This embodiment has the particular advantage that not only is the manufacture of a particular table type particularly simple, but that the customer himself also has the option of changing the table structure when restructuring his office by exchanging longitudinal members or side parts and thereby new purposes optimally adapt. Such a possibility is particularly important if, in a further embodiment of the invention, such a table has more than two columns and the longitudinal beams connecting the columns are arranged in a straight line and / or at an angle to one another. It is then very easy to change the structure of such a table, which consists of a large number of side parts and longitudinal struts, and thus to adapt well to new conditions.

In a special embodiment of the invention, the longitudinal beam is designed as a vertically arranged frame which is provided with connecting links near its upper and lower edge. The use of such a vertically arranged frame results in a structure of very high stability, because the connecting elements act on the pillars at a great distance and therefore form a large support base. As a particular advantage, the use of a frame offers the possibility of using vertical webs in the frame for attaching additional devices, in particular baskets for continuous forms. The design of such an office table can be varied in a particularly varied manner if the vertical bars of the frame and / or the webs inserted into the frame have a number of longitudinal slots which are preferably arranged at the same distance from one another for attaching supporting arms provided with corresponding hooks and additional devices.

Another particular advantage of using frames is that the connecting elements are arranged essentially on a vertical line, so that the columns do not have to have a large horizontal dimension. Thus, in a preferred embodiment of the invention, the columns have a circular cross section and have annular grooves which extend over their circumference and are open in the axial direction and into which hooks attached to the ends of the frame engage. Columns with a circular cross-section can not only be produced easily and at low cost from the corresponding tubular material, but also have the further advantage that they have no excellent directions for connecting longitudinal members. It is therefore easily possible to hang several longitudinal beams in the annular grooves, which can enclose almost any angle with one another, and in particular such columns can be used as nodes of star-shaped table arrangements.

The annular grooves can be formed in a simple manner by sleeves placed on the column, the lower of which is open at the top and the upper is open at the bottom. The vertical bars of the frames then expediently have longitudinal slots which are open towards their ends and which delimit hook-like sections of the vertical bars which engage in the sleeves.

In another embodiment of the invention, the columns are separated in the area of the annular groove, and their sections are connected to one another by an insert piece which has an annular recess. The one Column section ends flush with one flank of the annular recess, while the other column section projects beyond the other flank of the recess, but ends at a distance from the end of the one column section. The groove is thus formed by the interior of one column section and the adjacent section of the recess in the insert. This groove is accessible through the slot which is located between the two column sections arranged at a distance from one another. The particular advantage of this embodiment of the invention is that the construction of the column from a number of sections offers further variation options for the formation of the table. This applies in particular if the insert consists of two parts which are symmetrical to one another and abut one another in the central plane of the annular groove and which are fastened in the respective column sections and connected to one another by a central screw bolt. In this embodiment of the invention, the vertical spars of the frames can advantageously be formed in each case by a profile having openings on its side adjacent to the column, into which connecting pieces with a protruding, hook-shaped attachment are inserted.

In another preferred embodiment of the invention, the longitudinal beam is designed as a box-shaped hollow body which is provided with connecting members on its two vertical wall sections. The use of a side member in the form of such a box-shaped hollow body is of particular interest when an office table is required which has a cable duct extending over its length, because such a hollow body can be used very well as a cable duct. If such a cable duct is required, the side member can be advantageous be provided with a longitudinal slot arranged on its upper or lower side, optionally provided with a cover.

Since the stability of the connection between columns and side members depends to a certain extent on the spacing of the connecting links provided, it is advantageous if, when using a side member in the form of a box-shaped hollow body, the columns have an elongated cross section in a plane perpendicular to the side member and at least have on the side facing the side member two parallel rows of longitudinal slots arranged at the same distance from one another, into which hooks attached at the ends of the side member engage. This embodiment of the invention has the advantage that connecting links designed as hooks can be attached to the side member both with lateral spacing and with height spacing and can be hung in the longitudinal slots of the columns. A very high stability of the table frame can then also be achieved in this way. At the same time, the attachment of a large number of longitudinal slots in rows permits the attachment of the side member to the columns at any height. There is also the option of attaching several side rails one above the other if table frames with particularly high stability or special equipment are required.

While in the above-described particular embodiment of the invention an unwanted loosening of the connection between the longitudinal member and columns is prevented by the oppositely directed openings of the annular grooves, in the embodiment with the box-shaped longitudinal member a special protection against such unintentional loosening can be achieved in a simple manner be in the next at least one of the hooks is arranged in the longitudinal direction of the longitudinal member and preferably spring-loaded in the direction of the end of the longitudinal bar bolt which engages above the associated hook in the same longitudinal slot of the column as the hook itself and thereby prevents lifting of the hook. Nevertheless, after pulling back the latch, the connection can be released again at any time and without any damage to the components connected to one another.

In a preferred embodiment of the invention, the hooks and optionally the bolts are attached to an insert inserted into the ends of a hollow profile forming the longitudinal member. The use of special inserts, which can be inserted into the hollow profiles forming the longitudinal member, lowers the manufacturing costs by the possibility of producing large quantities of uniform components and using them for tables of different designs. This possibility is particularly important when longitudinal beams of different dimensions are provided according to a predetermined grid dimension, which enable a modular structure of an office table system.

The use of an insert inserted into the hollow profile also offers the possibility of bracing the longitudinal beam against the column by the insert being arranged displaceably in the hollow profile and being adjustable in the direction of the interior of the hollow profile by means of an eccentric. If the insert is connected to the column by its hooks, the end of the hollow profile is moved against the column by the displacement of the insert into the interior of the hollow profile and is thereby braced against the column. On in this way, a table frame with extremely high stability and resilience can be realized.

In a particularly preferred embodiment of the invention, the eccentric is formed by a rod which is rotatably mounted eccentrically in use and which engages with stops fitted in the hollow profile. Such a rod is easily accessible for twisting through slots or openings in the hollow profile and has a high stability, so that large clamping forces can be applied here. In addition, such a rod could be designed in such a way that it can be installed in the hollow profile even after the insert has been inserted into the insert, so that the stops available for interaction with the rod do not interfere with the insertion of the insert.

Columns that have an elongated cross section can be made in a particularly advantageous manner from two hollow profiles with a substantially rectangular cross section, on the mutually facing narrow sides of which open U-rails are attached, in the legs of which the elongated slots are located, and one connecting the hollow profiles to one another There is a central web, which has U-profiles encompassing the U-rails on both edges. This results in a column that is symmetrical with respect to two mutually perpendicular longitudinal center planes and is composed of very simple and at the same time very stable parts. The outer profiles with an essentially rectangular cross-section can on the one hand accommodate elements for connecting sections of the column to one another and of column sections with the foot, and can also partially serve as cable channels. The U-rails form together with the Hollow profiles have a very stable structure for making the connection to the side member. The use of a central web for connecting the outer profiles has the advantage that the outer profiles can both be of the same design and can have a smaller cross section, which is of great importance for economical production. At the same time, a particularly stable structure is achieved in connection with the middle web, which is again very simple to manufacture. In a particularly simple manner, the central web can consist of two sheet metal profiles arranged symmetrically to the connecting plane between the two hollow profiles, the edges of which are angled outwards and form the U profiles encompassing the U rails.

In the office table according to the invention, the table tops can rest on the support arms and be fastened to them in the usual manner, for example with screws penetrating the support arms from below and screwed into the table top. In this case, table tops of different embodiments can be supplied with support arms attached to them, if the side members are provided with devices for releasably fastening the support arms, for example again with slots, into which arms attached to the ends of the support arms can be hung. However, it is also possible to releasably fasten such table tops to support arms which are firmly connected to the side members, in order to enable them to be replaced if necessary. Here, too, a secure connection between table top and support arm is particularly achieved in that the table top rests on the support arms. A securing of the table top, by means of which a detachable connection is made at the same time, can then be achieved by means of bolts arranged on the underside of the table top and engaging in recesses in the support arms. Such latches can in particular be pivotally mounted on a support frame arranged on the underside of the table top, between the support arms and engage in the locking position with their ends in recesses on the mutually facing sides of the support arms such that they interact with a flank of the recess Define the position of the table top in relation to the table frame.

Further variations and adaptations to specific uses can be achieved in a simple manner in the office table according to the invention in that at least one of the side parts can be extended beyond the height of the table top by means of an adapted extension piece. Such an extension piece can in turn be provided with one or more support arms for additional table top elements and / or with fastening means for additional devices. Furthermore, at least one of the side parts on its outer side facing away from the longitudinal member can be provided with at least one support arm, preferably designed in the manner of a shortened longitudinal member, for an additional table top element and / or with fastening means for additional devices. In the preferred embodiments of the invention described above, both the annular grooves on the column, which is circular in cross section, and the parallel rows of longitudinal slots, which are also on the outside of the columns in the symmetrical structure of the column described, offer the possibility of a plurality of longitudinal beams to connect to a column and thereby create complicated table structures of all kinds.

The frame of an office table illustrated in FIG. 1 comprises three columns 1 to 3, each provided with feet 4 to 6 and connected to one another in pairs by frame-shaped longitudinal beams 8 and 9. The feet 4 to 6 are substantially perpendicular to the plane defined by the frame-shaped longitudinal beams 8, 9. The feet 4 and 6 attached to the outer columns 1 and 3 extend on both sides of this level, while the middle foot 5 is only arranged on one side of this level. The design and arrangement of the feet can depend on the load that results from the intended use of the office table. The columns 1 to 3 are formed by tubes of circular cross section, which are inserted into corresponding sleeves 10 of the feet and fastened therein.

The frame-shaped longitudinal beams 8 and 9 are detachably connected to the associated columns 1 and 2 or 2 and 3 by form-fitting interlocking connecting links. As can also be seen from FIG. 2, the vertical bars 11 are provided with a number of longitudinal slots 12 arranged at the same distance from one another. The longitudinal slots provided at the ends of the spars 11 are open towards the end of the spars, so that they each delimit a hook-like section 13 of the spar. With these hook-like sections, the vertical spars 11 engage in annular grooves 14, which are each formed by sleeves 15 and 16 placed on the column. 2, the lower sleeve 15 sits on the sleeve 10 of the foot and is open at the top. The hook-like section 13 at the lower end of the vertical spar 11 of the frame-shaped side member 8 engages in the annular groove 14 formed in this way. In a corresponding manner, one overlaps column 1 attached, downwardly open sleeve 16 the hook-shaped section 13 at the upper end of the vertical spar 11. This sleeve 16 is held by a plastic sleeve 17, which is pushed over the sleeve 16 onto the column 1 and with warts 18 in corresponding holes in the column 1 is locked. This sleeve 17 can consist of a limitedly deformable material which also exerts a pressure in the axial direction on the sleeve 16 and thereby ensures a play-free form fit between the sleeves 15, 16 and the hook-like sections 13 on the vertical spar 11 of the frame-shaped longitudinal member 8. A cap 19 placed over the cuff 17 holds the cuff 17 in place and also ensures that the column 1 is sealed off at the top.

Supporting arms are used to support table top elements and extend transversely to the longitudinal beams 8, 9. There are different ways to attach such support arms. In the embodiment shown in Fig. 1, support arms 20 are attached directly to the upper longitudinal spar of the frame-shaped longitudinal member 9, for example welded. Other support arms 21, on the other hand, are provided on their underside with support arms 121 which have hooks on their edges facing the frame-shaped longitudinal member 8, by means of which they are hooked into the longitudinal slots 12 of the vertical bars of these longitudinal members. In this way, it is possible, as shown in FIG. 1, to mount such support arms 21 on both sides of the longitudinal beam 8 at different heights. In this way, a table top that is stepped in height can be obtained, as is particularly advantageous for setting up screens with a keyboard. The frame-shaped design of the longitudinal beams 9 not only results in a high stability of the table frame because the connection between the longitudinal beams and the column takes place at widely spaced locations, but it also allows the frame-shaped longitudinal beams to be used with vertical webs 22, which are similar to the vertical bars 11 of the frame-shaped longitudinal members are provided with longitudinal slots 23, which enable the attachment of support arms and additional devices.

Fig. 3 shows a variant of the office table shown in Fig. 1, in which the columns 1 are provided with mushroom feet 24. Support arms 21 are arranged only on one side of the longitudinal beam 8 and are provided with a table top 25. The table top 25 is fastened to the support arms 21 by means of screws which penetrate the support arms 21 from below. On the side of the longitudinal beam 8 opposite the table top 25, paper baskets 26, 27 for endless forms are arranged, both of which are suspended in the longitudinal slots of vertical webs 22, which in turn are inserted into the frame-shaped longitudinal beam 8. This office table with the one-sided top and the paper baskets for continuous forms is especially suitable for the installation of a printer.

In the variant of an office table according to the invention shown in FIG. 4, the columns are composed of several sections, each of which collide in the region of an annular groove 33 which is intended for hanging a frame-shaped longitudinal member 34. To form this annular groove 33 and the connection of the column sections 31, 32 2 parts 35, 36 are inserted into these column sections, which together form an insert. Both parts 35, 36 consist of one cylindrical body, which is followed by a section 37 of reduced diameter. The parts 35, 36 are fastened in the column sections 31, 32 in such a way that the sections 37 of reduced diameter face the ends of the column sections. The part 36 is inserted into the upper column section 32 such that the end face at the transition to the section 37 of reduced diameter is flush with the end of the tubular column section 32. In contrast, the part 35 is fastened in the lower column section 31 such that the end of the tubular column section 31 is flush with the end face of the section 37 of reduced diameter. The parts can be fastened in the column sections by welding. In addition, a screw 38 is inserted into a central bore of one part 36 and has a threaded shaft 39 protruding from the section 37 of reduced diameter, with which it is screwed into a central threaded bore 40 of the other part.

In the annular groove 33, delimited on the one hand by the insert piece 35, 36 and on the other hand by the protruding edge of the lower column section 31, a hook-shaped extension 41 engages, which is located on a connecting piece 42 which is in the vertical spar of the frame-shaped longitudinal member formed by an angular profile 43 34 is used. In the exemplary embodiment shown, this connection piece 42, which is positively guided in the angular profile 43, is fixed in its position by a screw 44. This arrangement has the particular advantage that the column of the office table can be composed of sections of different lengths as required and also easily the use of frame-shaped side members of different lengths Height is possible. The connecting pieces 42 allow height adjustment of the frame and accordingly also of components attached to it. On the other hand, it would be possible to provide the vertical spar also on its side facing the column with a number of spaced-apart longitudinal slots, into which corresponding connecting pieces then engage, which are held by clamping plates arranged inside the spar. This creates a positive connection with a particularly high load capacity.

The embodiment according to FIGS. 5 to 9 corresponds to the previously discussed exemplary embodiments in that side parts, which consist of columns 52 provided with feet 51, are connected to one another by a longitudinal beam 53 to form a table frame. The connection is again made by hooks 54, which are attached to the ends of the longitudinal beam 53 and engage in a form-fitting manner in corresponding recesses on the columns 52. Support arms 55, on which table tops 56 rest, are fastened to the longitudinal beam 53. The difference from the previously discussed exemplary embodiments essentially consists in the shape of the columns 52 and the longitudinal beam 53.

As can be seen in particular from FIGS. 6 and 7, the column 52 has two hollow profiles 61 which have a substantially rectangular cross section, even if they are rounded off towards the outside. These hollow profiles 61 have, on their mutually facing narrow sides, U-rails 62 which are open to the outside and which engage with their legs in U-profiles 63 which engage on the edges of a central web 64 which connects the U-rails 62 and thus also the hollow profiles 61 to one another are located. The result is a structure which takes up little space and is very stable, which also has the advantage that it is composed of a few profiles. It is symmetrical both to a plane containing the longitudinal central planes of the two hollow profiles and to a central plane perpendicular thereto. The central web consists of two sheet metal profiles 65, 66 which are arranged symmetrically to the connecting plane between the two hollow profiles 61 and which have outwardly angled edges which form the U profiles 63 encompassing the U rails 62. To establish a connection to the longitudinal beam 53, the U-rails 62 have longitudinal slots 67 in their legs, into which the hooks 54 engage at the ends of the longitudinal beam. Furthermore, fastening means are arranged in the hollow profiles 61, such as, for example, the nuts 68 shown in FIGS. 6 and 7, which make it possible to establish a connection to adjacent components, such as to the feet 51.

As shown in FIG. 5, the longitudinal beam 53 in the exemplary embodiment shown there consists of a box-shaped hollow body which has a longitudinal slot 71 on its underside, which enables the insertion of electrical lines. Furthermore, there is a central opening 72 at the top of the side member, which can be closed by a cover if necessary. This design of the side member enables its use as a cable duct. The hooks 54 used for connection to the columns 52 are not attached directly to the side member 53, but rather to inserts 73 which are inserted into the ends of the side member 53 and fastened therein. As FIG. 8 shows in more detail, such an insert 73 consists of an essentially U-shaped one Component whose crossbar spans the longitudinal slot 71 on the underside of the longitudinal beam 53. On the inside of the two legs 74, two plates 75 and 76 are fastened, which project at one end over the lateral edges of the leg 74 and form a hook 54 there. Form between the plates 75, 76. Between the plates 75, 76, a bolt 77 is slidably mounted in the longitudinal direction of the side member. The two bolts 77 are connected to one another at their ends opposite the hooks 54 by a rod 78, on which helical tension springs 79 engage, which strive to hold the bolts in a rest position in which the pointed ends adjacent to the hooks 54 enter into the same longitudinal slots 67 of the columns engage as the adjacent hooks 54. The coil springs 79 ensure that the portion of the respective longitudinal slot 67 remaining above the hooks is completely filled by the tip of the bolt 77, so that it is impossible to remove the adjacent hooks 54 from the Dig out longitudinal slot of column 52. In this way, a very secure connection is established between the longitudinal beam 53 and the columns 52, which, however, is easily detachable after the latch 77 has been withdrawn.

As already mentioned, support arms 55 for the table top 56 are attached to the side member 53. The support arms can be welded, screwed or otherwise attached to the side member. In the embodiment shown in FIG. 5, a table top 56 is provided on both sides of the longitudinal beam 53. The table tops rest on the support arms 55 and are thus given good support. Here, the table tops 56 are releasably attached to the support arms 55, so that they are easily interchangeable with other table tops that have a different shape and / or can have a different surface. Of course, it would also be possible to replace the table tops with any additional devices.

In the illustrated embodiment, bars 81, which are pivotably mounted on a support frame 82, which in turn is fastened to the underside of the table top 56, serve for the connection between the table top 56 and the support arms 55. The support frame 82 consists essentially of a bar extending parallel to the side member 53, at the ends of which are attached cross bars 83 which fit straight between the support arms 55 attached to the side member 53. On the mutually facing inner sides of the support arms 55 there are recesses 84, in each of which a latch 81 engages with its short arm 85 when the latch assumes the latching position shown in FIG. 9. The side surface of the short arm 85 lies against the outer flank 86 of the cutout 84 in the support arm 55 and thereby presses the table top 56 against the side surface of the side member 53. By pivoting the bolt 81 in the direction of arrow 87, the bolt 81 can be locked with the Disengage support arm 55 and then detach the table top from the support arms.

Figures 10 to 13 show the essential components of a further embodiment of an office table, which is characterized by a particularly high stability. The high stability is achieved by the large width of the columns 110 and the longitudinal beam 111, which provide a large support base, and a special design of the insert 112.

The column 110 consists of two square tubes 113 arranged at a distance from one another, which in turn have a number of longitudinal slots 114 on their mutually opposite outer sides, which are arranged at a distance from one another and allow components to be hung in. The two square tubes 113 are connected to one another in the plane of one of their side faces by a plate 115, while bead-shaped profiles 116 adjoin the outer sides of the square tubes 113. These profiles 116 have a greater width than the square tubes 113 and delimit a space into which a cover plate 117 can be inserted, which has hooks 118 on its inner side facing the square tubes 113, which can be hooked into the longitudinal slots 114 of the square tubes 113, thereby to attach the cover plate 117 to the column. The cover plate 117, which is releasably connected to the square tubes 113 of the column 110 by means of the sheets 118, is accordingly easily exchangeable, so that it enables the surface structure and work of the table frame to be adapted to existing devices. If necessary, the overall impression of the table can also be influenced by specially shaped cover plates. The column 110 is closed at the top by a cover 119 th, which has ends 120 which fit into the bead-shaped profiles 116 at its ends.

he longitudinal beam 111 also in this embodiment of the invention consists of a box profile open at the bottom, the width of which is adapted to the distance between the square tubes 113 of the columns 110. In this exemplary embodiment, the insert 112 used to connect the longitudinal beam 111 to the column 110 consists of two separate parts, only connected to one another by a rod 121 are, which corresponds to the rod 78 of the insert of FIG. 8. Each of the two parts of the insert 112 is guided and slidably supported in a groove 122, which is formed by angled edge sections 123, 124 of the side member 111.

The two parts forming the insert 112 each consist of a bearing bracket 125 which fits into the channel 122 and on the inside of which a hook part 126 is fastened. The position of the hook part 126 in the bearing bracket 125 is determined by slots 127 in the bearing bracket, into which the hook parts 126 engage with lugs 128 attached to their upper and lower edges. At a section protruding from the front end of the bearing bracket 125, the hook part 126 has three hooks 129 arranged one above the other, the size and spacing of which are adapted to the longitudinal slots 114 in the square tubes 113. The use of three hooks 129, which come into engagement with three adjacent longitudinal slots 114 of the square tubes 113, results in a very high load-bearing capacity of the connection between the longitudinal beam and the columns.

Similar to the embodiment according to FIGS. 5 to 9, a bolt 130 is used to secure the hooks 129 in the longitudinal slots 114, which bolt is slidably mounted in a groove 131 formed by a bent portion of the hook part 126. The effect of this bolt is the same as in the embodiment according to FIGS. 5 to 9. Here, too, a helical tension spring 132 strives to hold the bolt 130 in its locked position. The coil springs 132 engage the rod 121 connecting the parts of the insert and are in each case with their other ends hooked a hook 133, which is pressed out of the hook part 126 in the region of the groove 131.

The bearing brackets 125 each have a tab 134 on their rear edge opposite the hooks 129. The lobes of the parts connected to one another to form an insert 112 form the bearings for an eccentric 135 which is formed by a rod which has axial but eccentrically arranged bores in its end faces. Bearing pins 136 are inserted into these bores, the inner ends of which are supported by helical compression springs 137 at the base of the bores which receive the bearing pins. In the area of its center, the eccentric 135 has two adjacent transverse bores 138 arranged at right angles to one another. The eccentric 135 is intended to interact with stops 139 arranged inside the grooves 122 of the longitudinal beam 111, which in the exemplary embodiment shown are formed by pins fastened in the edge section 123.

To connect the side member 111 to the column 110, the parts of the insert 112 are inserted into the grooves 122 of the side member 111. The eccentric 135 is not yet hooked into the tab 134 of the parts. These tabs can therefore be easily pushed past the stops 139 arranged in the channels 122. Thereafter, the eccentric 135 is suspended from below by pressing the bearing pins 136 into the tabs 134 of the insert parts, so that the eccentric 135 lies behind the stops 139 with respect to the open end 140 of the side member. The longitudinal member with the hooks 129 of the insert can then be inserted into the longitudinal slots 114 of the square tubes 113 of the column 110 be hung up. It would also be possible to first connect the insert to the column, then slide the side member onto the insert and then hang the eccentric in the tabs 134 of the insert. Then, by inserting a mandrel into the transverse bores 138, the eccentric 135 can be rotated so that its periphery comes to rest against the stops 139 and moves the stops with respect to the insert 112 in the direction of the hook thereof, as a result of which the end 140 of the longitudinal beam 111 touches the surface of the column facing him is pressed. The angle between the eccentric surface and the stops 139 is so small that very large clamping forces can be exerted and self-locking also occurs, so that an extraordinarily high stability of the connection is ensured here. The eccentric can be rotated by means of a mandrel inserted into the transverse bores 138 both from the open underside of the longitudinal beam 111 and from an opening 141 arranged in the upper side of the beam.

It is readily apparent that, due to the interaction between the eccentric and the stops, each of the two parts of the insert 112 acts independently of the other, so that a rigid cross-connection between the two parts is not necessary. Furthermore, it is readily apparent that after loosening the eccentric, the previously established connection can be easily released again, so that the components can be used again for producing other configurations.

Similar to the office table according to FIGS. 1 to 4, the office tables according to FIGS. 5 to 9 and 10 to 13 in modify in many ways and adapt to special purposes. So the table size and table height can be easily varied by using columns 52, 110 of different lengths or also longitudinal beams 53, 111 of different lengths. The column, which extends straight up to table height, can be closed by a cover 57 (FIG. 5), but can also be extended by an attachment 58. In this case, support elements 59, which are designed similarly to the longitudinal beam 53, can also be connected to the outside of a column 52. It is understood that similar support elements can also be connected to the extension 58 of the column. Table combinations can also be created in which several columns are connected in pairs by longitudinal members. 14 shows an example of such an arrangement. Between the two left columns 91, 92, a longitudinal member 93 is arranged at such a height that a table top attached to the support arms 94 is at desk height. On the outside of the left column 91 there is a support element 96, which enables the attachment of a slightly lower worktop, as is required for a typewriter, computing machine or other office equipment.

Progressing clockwise, the column 92 is followed by a column 97 which is connected to the column 92 by a longitudinal beam 98 which has angled lugs 99 at its ends, so that a corner table results here. The longitudinal beam 98 is in turn lower than the longitudinal beam 93 of the adjacent desk frame, so that this corner table is again suitable for storing office equipment. The column 97 in turn forms the frame of a desk together with the column 100 and the longitudinal member 101. The column 101 is higher than the normal desk height and extends up to standing desk height. The outer column 102, which is connected to the column 100 by a longitudinal beam 103, also has a corresponding height.

Fig. 14 is intended to illustrate that the invention offers the possibility to create office tables of different configurations and to mount the table tops at an optimal height for the respective purpose. It is also easily possible for the user of such office desks to change the compilations and to add them if necessary. Similar to the embodiment according to FIGS. 1 to 4, also in the embodiments according to FIGS. 5 to 9 and 10 to 13, several longitudinal beams can be suspended in the columns at different heights, for example to attach table tops at different heights or also by one To form a recording for additional devices of various types. In all of the exemplary embodiments, by providing components with different dimensions that fit into a grid system, furniture systems can be created that can easily be optimally adapted to all practical purposes.
