Referring now to the drawings and in particular to FIGS. 1-6, in all shown one-column tables, the latter have a U-shaped supporting frame. The stay of this U-shaped supporting frame forms the table column 1, which table column and is formed telescopically. The lower outer telescope part 2 of the table column receives an upper inner telescope part 3. Both telescope parts comprise tubes having a square cross section and lead flushly into each other.

From the lower end of the telescope part 2 extend the horizontally provided foot-arm 4. The latter is angled at its free end and carries thereat the running roller 5. The foot-arm 4 has connected thereto a crossbeam 6 within the range of the table column 1. The crossbeam 6 is pivotally connected over the pin 7 with an arrangement of intermediate slide plates 8. The crossbeam 6 can thereby be turned in the longitudinal direction of the foot-arm 4. By this arrangement a saving can be obtained in known manner with the least space requirement and in particular in connection with the table plate 9 which is likewise tiltable.

The free ends of the crossbeam 6 are equipped with running and directing rollers 5, respectively.

The inner telescope part 3 extends into a right angular extension constituting the horizontal arm 10 disposed parallel to the foot-arm 4.

This horizontal arm 10 carries the table top 9. Two bearing members in form of supporting angles 11 and 11' are secured at corresponding points of the bottom side of the table top. An adjusting handle 12 permits the variation of the inclination of the table top and the inclination of the table top 9 into the table frame plane, respectively, in order to realize the desired space saving collapse.

The handle 13 is provided for the height adjustment of the table top. Concerning this adjusting possibility, one deals with the conventional clamping screw, which is equipped with an adjusting wheel, and which under certain circumstances is effective with its end edge by interposition of a pressure member against the inside disposed telescope part.

A supporting stay is coordinated to the one column table. This supporting stay can be brought into a position for the support of the table top, if the latter is exposed to greater load.

In accordance with the first embodiment, shown in FIGS. 1 to 6, this supporting stay 14 is provided and received by the horizontal arm 10. The latter is formed of a hollow profile, preferably a box profile. In order to effect the supporting position, the supporting stay is rolled out from the free end of the horizontal arm 10 and is brought into the position shown in FIG. 2.

A limit for pulling out of the supporting stay is provided, in order to secure the supporting stay in the one-column table without possible loss thereof. For this purpose a core member 15 is provided. The latter has a guide section 16 extending beyond the diameter of the core member. This guide section 16 has a round cross section. Its shoulder 16' points in the direction of the horizontal arm end and projects towards a stop 17 in the horizontal arm 10 forming an abutment limit.

The core member 15 and a supporting stay 14 are pivotally connected together. The corresponding pivot pin 18 is there disclosed in the drawing (FIGS. 3 and 4). A filler member 19 is inserted in the supporting tube end pointing inwardly, which forms the bearing members 20 by a fork arrangement.

As can be ascertained from FIG. 4, the supporting stay 14 finds an abutment in its supporting position at the end edge of the horizontal member 10 and at the supporting angle 11 preset to the latter, respectively. Since the core member 15 in the horizontal arm is disposed rotatably in the horizontal arm 10, it is not required, to tilt the supporting stay 14 exactly into the plane of the table frame; rather the user of the table 10 can choose the angular position appearing most convenient for him. It is recommended to extend the supporting stay, only after the hanging position of the latter is assumed, which is given by the ability of telescoping the supporting stay.

The supporting stay part 14' which can roll out from the outer supporting stay part 14", is equipped with a shoe 21. The latter is adapted to grip over the foot-arm 4. Seen in cross section, this shoe assumes the shape of a U-profile. The rolled out position of the supporting stay is securable by means of a set screw 22 with a hand wheel.

In order to exclude an undesirable striping off of the shoe 21 from the foot-arm 4, a considerably different holding means are provided. In accordance with FIG. 5 rest springs 23 are applied. The latter sit on inner walls of U-arms. They are secured at one end. The bump-shaped projections of the springs cooperate with recesses 24 at the corresponding outer walls of the foot-arms 4. In accordance with FIG. 8 it is proposed, to equip the U-stay with an elastic plate having teething 25. Finally, in accordance with FIGS. 9 and 10 it is proposed, to equip the free end of the supporting stay 24 with a center pin 26 rounded at its front end, which pin 26 enters a corresponding opening 27 at the upper side of the foot-arm 4.

The inserting movement of the supporting stay 14 is finally limited by a ring 28 being shrunk thereon (see FIG. 3).

Referring now to the variations disclosed in FIGS. 11 to 13, the supporting stay 14'", in case of nonuse, can be brought into a coaxial position laterally of the horizontal arm 10. The design is made such, that the horizontal arm 10 has a longitudinal slot 29. The latter serves a guiding of a holding pin 30 of the supporting stay 14'". The holding pin 30 enters with a stop behind the inner slot edge zone. The support of the supporting stay within the range of the free end of the horizontal arm takes place by means of a console in form of a cup 31. In order to put the supporting stay into operative position, it is merely required, to lift the supporting stay within the range of this cup 31 and to swing the latter upwardly. In addition this supporting stay is comparable with the previously described supporting stay and in particular in connection the shoe formation as well as the possibility of telescoping. In supporting position the supporting stay 14'" moves, limited by a stop, against the angular sheet metal 11. By this arrangement the pin 30 enters into the angular slot 29'.

Referring now again to the drawings and in particular to the embodiment disclosed in FIGS. 14-17 the shoulder 16' of the guide section points in the direction of the free end of the horizontal arm against the end edge of the carrier 17' and constitutes an abutment limit and is connected integrally with the bearing member 11.

In the supporting position the supporting stay 14 finds an abutment limit at the edge end of the horizontal arm of the carrier 17' designed in form of an angular bearing member.

The outer part 14" of the supporting stay has at its free outer end a corresponding threaded bushing 33 for the set screw 22 which with its front end 22' effects the jacket of the supporting stay inner part 14', by projecting through a bore 34 of the outer supporting stay part 14".

The insert position of the supporting stay into the horizontal arm is securable. For this purpose a holding projection 35 is formed on the carrier 17' extending bushinglike in the horizontal arm and disposed on the under side of the table top 9. The carrier 17' has a passing opening 36 for the supporting stay 14 extendable from the horizontal arm 10.

The holding projection 35 is disposed directly above this passing opening 36 and is of fork-shape. Forked arms 37 are provided (see FIG. 17), which are undercut. They surround the greatest part of the periphery of the threaded bushing 33 for the set screw 22, which is disposed crosswise at the outer free end of the outer supporting stay part 14". Preferably, the entrance opening 38 for the threaded bushing defined by the forked arms 37 is fitted substantially to the contour of this bushing. Upon insertion of the bushing the forked arms 37 yield resiliently for the required length, in order to assume again the original position upon entering of the bushing into the opening 38, in which position they fix the supporting stay in the assumed position.

The carrier 17' has in the horizontal arm 10 above the holding projection 35 a windowlike opening 39 for entering of the setting wheel 33 of the set screw 22. This design serves the object to remove substantially from view all of the setting means. The height x of the setting wheel corresponds with the open height y of the windowlike opening 39. The setting wheel 32 can thus enter first into the window 39 in the desired manner, if before the inner support stay part 14' has been secured relative to the outer supporting stay part 14", either in the completely moved in position shown in FIG. 14 or a pulled out position, in which the supporting stay part 14' can be used for overhanging of any objects.

Referring now again to the drawings and in particular to FIGS. 18 to 24, still another embodiment is disclosed in which the supporting stay 14 can be brought out of its coaxial position to the horizontal arm 10 gripping the horizontal arm 10, into the supporting position in accordance with FIG. 19. The swingability is given by a pivotal connection. For this purpose the outer free end of the horizontal arm has a bearing pin 41. The latter passes a filler member 42 inserted stopperlike into the free front end of the horizontal arm formed hollow at least at this point. The bearing pin 41 secures simultaneously this filling member 42 on the horizontal arm 10. The filling member 42 has furthermore a stop 43, which engages the mentioned front end.

Outwardly the filling member 42 is transformed into an axle pin 44 making possible the tilting movement of the table top 9. The axle pin 44 enters a bearing eye 45 of the carrying angle.

The supporting stay 40 is formed of a U-profile. The latter has a greater clear width than the cross section of the horizontal arm 10 (see FIG. 24). In the example the supporting stay 40 is formed of two telescopelike extendible and boxed into each other U-profiles. The supporting stay part 40' on the pivot side is inserted and guided, respectively, in the extendible supporting stay part 40". Also in the telescope formation of the supporting stay, the clear width of the inner U-profiles is greater than the cross section of the horizontal arm 10.

For the pivotal connection of the supporting stay 40 and of the supporting stay part 40', respectively, at the horizontal arm 10 are the U-arms 46 of the U-profile forming the supporting stay part 40'. The stay 47 of this U-profile is backwardly relative to the rounded end edge of the U-arm 46. The thus created forklike bearing laps are equipped with a bore 46' for the bearing pin 41.

The U-stay 47 is backwardly disposed in addition so far relative to the end edges of the U-arms, that a front face 47' is obtained which limits in the supporting position a buckling of the supporting stay, which front face 47' finds its abutment at the horizontal arm 10 and its filling member 42, respectively.

The front end of the supporting stay 40 is in addition rounded up, as shown in the drawing.

In tilted position the supporting stay grips, due to the U-profile, the horizontal arm 10. This assumed tilted position (see FIG. 18) is secured by a resting means. The formation of the resting means takes place here as shown such that the horizontal arm 10 has at its wide sides a rest recess 48'. If the supporting stay 40 is made of two telescopically extendible part members, the rest recess can be provided advantageously in a material lap mounted thereon while in case of use of a nontelescopic supporting stay directly on the mentioned sidewall of the horizontal arm 10.

The corresponding counterresting means is disposed in form of nipples 49' at the free end of the supporting stay 40. These nipples 49' sit on the freely projecting U-arms 49 of the U-shaped supporting stay part 40".

In supporting position the nipples 49' enter a rest recess 48 of the foot-arm 4. Here also the U-stay 50 of the U-profile is removed backwardly relative to the downwardly freely projecting U-arms, so that on the one hand the resilient characteristic of the parts having the nipples is available, on the other hand, however, an end edge 51 is realized, which supports itself directly on the upper side of the foot-arm 4.

For telescoping of the supporting stay parts 40' and 40" the U-arms 46 have a longitudinal slot 52, in which, on the one hand, a slot pin 53 projecting from the arm of the supporting stay part 40" enters and, on the other hand, a set screw with a hand wheel 54 for the fixing of the position of the extended position. The corresponding longitudinal slot is worked in the form of a groove.

Referring now again to the drawings and in particular to FIGS. 25 to 27, still another embodiment is disclosed, in which a supporting stay 55 is arranged in the foot-arm 4, which comprises a tube of square cross section. In order to bring about the supporting position the supporting stay 55 is pulled out from the free end of the foot-arm 4 and is brought into the position disclosed in FIG. 26.

As can be ascertained from FIG. 26, the supporting stay 55 finds in its supporting position an abutment at the front face 56 of the foot-arm 4.

The inner supporting stay part 35' carries at its outer end the U-profiled shoe 21, which surrounds engagingly the horizontal arm 10. For a better arresting the shoe 21 has at its arms 21' the pushing-in nipples 57. The latter enter into engagement with the corresponding cavities 58 of the horizontal arm 10. In this rest position the shoe 21 forms with its stay 21" the support for the horizontal arm 10. Only upon resting of the shoe it is advantageous to secure relative to each other the supporting stay part 55' and 55" by means of the set screw 22.

The table top-carrying angle 11 mounting at the free end the horizontal arm 10, serves a securing of the vertical position of the stay 55 in its operative position, so that the latter cannot be brought out undesirably from its resting position, as of for instance by an inadvertently performed jolt.

The inserting movement of the supporting stay 55 is also in this embodiment limited by a ring 28 preferably of synthetic material. The latter sits at the outer end of the supporting stay part 55" and enters with abutment limitation against the front face 56 of the foot-arm 4.

Referring now still further to the drawings and in particular to FIGS. 28 to 32, this embodiment shows likewise a coordination of the supporting stay on the foot-arm. In this embodiment the supporting stay 60 comprises two telescopelike extendible and boxed into each other U-profiles, in the inner space of which the foot-arm 4 is arranged. The supporting stay part 60' is mounted by means of the bearing pin 61 at the forward end of the foot-arm 4. For this purpose serve the sections 63 formed by the U-arms and projecting beyond the U-stay 62. The U-stay end edge 64 finds thereby an abutment on the foot-arm 4 in the supporting position of the supporting stay 60.

The clear width between the U-arms of the supporting stay part 60' is provided slightly larger, than the cross section of the foot-arm 4. On this U-profiled supporting stay part 60' the supporting stay part 62' guides itself on the pivot side thereof. This supporting stay part 60" has likewise the sections 66 formed by the U-arms and projecting beyond the U-stay 65. The sections 66 have pushed-in nipples 67, which in the operative position of the supporting stay enter a rest with corresponding cavities 68 of the horizontal arm 10. The front edge 69 of the U-stay of the supporting stay part 60" forms the operative position of the stay 60, the support.

In tilted position due to the U-profile of the supporting stay 60, the latter grips the foot-arm 4. This tilted position is likewise secured by a rest. The pushed-in nipples 67 of the section 66 enter thereby in cavities 70 of the foot-arm 4.

The cavities 68 and 70 are disposed preferably in correspondingly thick material laps 71 disposed at the foot-arm and at the horizontal arm 10, respectively.

It is, however, also possible to extend the sections 66 of the supporting stay part 60" up into the range of the table column 1 and to provide there the corresponding cavities 70 for the pushed-in nipples 67.

In order to make possible a telescoping of the supporting stay parts 60' and 60", the U-arms of the supporting stay part 60' have a longitudinal slot 72, into which enters on the one hand, a slide pin 73 projecting from the arm of the supporting stay part 60" and, on the other hand, a set screw with a hand wheel 74 for fixing of the position in the pulled-out position. This particular longitudinal slot 72 is likewise worked in only in the form of a groove.

Referring now still again to the drawings and in particular to FIGS. 33 to 35, the supporting stay 75 is formed by two flat raillike stay parts 75' and 75", which are extendible relative to each other. This stay part 75' is disposed at the front side on the one wide side of the foot-arm 4 at the pivot pin 76.

The extendible stay part 75" has a longitudinal slot 77. A pin 78 is disposed on the supporting stay part 75' and projects through the longitudinal slot 77 and serves the guidance of this stay part. Furthermore, the longitudinal slot 77 is passed through by a setting screw 79, which enters a threaded bore 79' of the supporting stay part 75' and serves the position fixing in the extended position.

The outwardly arranged stay part 75" has at the transfer to the shoe 80 a crank 81 pointing towards the foot-arm 4. This shoe disposed at the free end of the supporting stay 75 has two entrance openings 82 and 83 arranged perpendicularly relative to each other. The one opening 82 serves as a supporting entrance of the horizontal arm 10, while the other opening 83 serves the entrance of the foot-arm 4 in coaxial position between the foot-arm 4 and the supporting stay 75. The width U of the entrance opening 82 corresponds with the cross section of the horizontal arm 10, while the clear width V of the entrance opening 83 corresponds with the cross section of the foot-arm 4.

The table top-carrying angle 11 forms in an advantageous manner an abutment of the shoe 80 of the supporting stay 75.

In this arrangement it is also possible to secure the supporting position and the tilted coaxial position of the supporting stay 75 additionally by corresponding rest devices.

Referring now still again to the drawings, and in particular to FIGS. 36 to 39, the supporting stay 84 can be brought into coaxial engagement to the table column. The supporting stay 84 comprises in this embodiment two stay parts 84' and 84" telescopically extendible relative to each other. At the end side, the outer stay part 84' carries a set screw 85 with a hand wheel for position fixing of the stay parts 84' and 84" in the extended position. The set screw 85 is arranged on the stay part 84' such, that it is disposed on the side remote from the table column 1 of the supporting stay 84, so that the latter in case of nonuse engages in parallel arrangement the column 1 (see point-dotted showing of the supporting stay in FIG. 36).

At the end side the supporting stay 84 has the guide shoes 86 and 87. The guide shoe 86 is formed of freely cut sections 88 of the inner stay part 84". The latter are outwardly cranked and surround forklike the horizontal arm 10.

The guide shoe 87 of the outer stay part 84' has likewise freely cut sections 89, which surround forklike the horizontal arm 10.

The sections 88 of the inner stay part 84" are passed by a supporting stay guide bolt 90. The latter is guided in a longitudinal slot 91 of the horizontal arm 10. At the free end of the horizontal arm 10 the longitudinal slot 90 is transformed to an upwardly directed resting recess 92.

The sections 89 of the outer stay part 84' have likewise a supporting stay guide pin 93 which guides itself in the longitudinal slot 94 of the foot-arm 4. This longitudinal slot 94 has at its end side the upwardly directed resting recess 95 (see FIGS. 35-38).

In operative position of the supporting stay 84, the supporting stay guide bolts 90 and 93 enter into the upwardly directed resting recesses 92 and 95, so that the supporting stay is secured against lateral displacement. It is, however, also possible that the supporting stay 84 assumes an intermediate position (see FIG. 36).

In case of such deviating design, shown in FIG. 39, at least one upwardly directed resting recess 96 is provided in the horizontal arm 10. This design permits in favorable manner a parallel displacement of the supporting stay 84 until its vertical supporting position is reached, in which the supporting stay guide bolts 90 and 93 enter the rest recesses 95 and 96.

The loads of the table top favor the entrance of the supporting stay guide bolt into the resting recess 96 of the longitudinal slot of the horizontal arm 10. In particular in this design, the supporting stay 84 can assume a diagonal position during its operative position, in which the supporting stay guide board 90 is arranged in the resting recess 96 of the horizontal arm 10 and the bolt 93 supports itself at the end 97 of the longitudinal slot 96 of the foot-arm 4 (see point-dotted line showing the supporting stay in FIG. 39).

This position is suitably chosen when no person sits at this one column table, rather the table serves only the support of a heavier object, as for instance a television receiver set.

While we have disclosed several embodiments of the present invention, it is to be understood that these embodiments are given by example only and not in the limiting sense.
