Furthermore, it is of advantage, if, in accordance with the present invention, the holding projection sits on a carrier disposed on the bottom side of the table top and extending bushinglike into the horizontal arm, which carrier has a passage opening for the supporting stay being extendable out from the horizontal arm.
  • the carrier has above the holding projection an opening for receiving a setting wheel of the screw.
  • the supporting stay which is swingable from its supporting position into the coaxial position to the horizontal arm, surroundingly receives in its coaxial position the horizontal arm.
  • An advantageous structure resides thereby, in accordance with the present invention, in the fact that the supporting-stay comprises a U-profile of larger clear width, then the cross section of the horizontal arm or foot-arm, and the axle pin between the supporting stay and the arm is disposed in the range of the U arms of the supporting stay. It is favorable thereby, if the front end of the supporting stay disposed on the side, of the fixing is rounded up.

  • a further advantageous feature of the present invention resides in the fact, that on the end of the supporting stay disposed on the pivot side project the U-arms beyond the U- stay, and in the supporting position the end edge of the U-stay finds an abutment at the lower edge of the horizontal arm.

  • a further advantageous variation resides, in accordance with the present invention, in the fact, that the latch-shaped, flat supporting stay pivoted tiltably to the one wide side of the foot-arm has at its free end a shoe with two entrance openings, which are perpendicular relative to each other and of which one opening serves for the supporting entrance of the horizontal arm and the other opening for the entrance of the foot-arm in the coaxial position between the foot-arm and the supporting stay.
  • the latch-shaped supporting stay comprises two stay parts guided relative to each other by way of a longitudinal slot and capable of being extended relative to each other, whereby the stay part disposed outwardly has at the transformation to the shoe a crank arrangement directed towards the foot-arm.
  • the supporting stay is extendable telescopelike and the set screw for the capability of being telescoped is disposed on the side of the supporting stay remote from the table column. Also it is favorable, in accordance with the present invention, if the supporting stay is locked in the supporting position, preferably due to upwardly angularly disposed rest recesses at the foot-arm and at the horizontalarm for the entrance of the supporting stay guide-bolts.
  • An advantageous structure is in this connection, in accordance with the present invention, realized such, that at least at the horizontal arm an upwardly directed resting recess for the entrance of the supporting stay guide-bolts is provided.
  • the supporting stay is not required for the additional support of the table plate or the table top, it can be completely taken out of view into a hiding position, either into the horizontal arm present in the form ofa box profile or laterally thereto in equal direction extension, either by rolling into the foot-arm, tilting against the foot-arm or displacing of the stay into coaxial position to the table column.
  • the supporting stay remains however always without fail at the table.
  • the supporting stay itself can be formed telescopically expandible, and is capable of fulfilling this task in each set height position of the table top.
  • the danger does not exist, that the supporting stay in case of requirement is displaced at that moment.
  • Even in supporting position the full freedom for the legs of the user is retained in most solutions in spite of the exercise of a good supporting function.
  • a favorable withdrawal extension limit for the desired impossibility of losing the stay is obtained.
  • the supporting stay in coaxial position to the foot-arm brings about a favorable displacement of the gravity center of the onecolumn table, thereby increasing the standing stability.
  • the telescopelike adjustability of the two supporting stay profile assures, that the supporting stay can always be shortened for a length, which corresponds at the most with the length of the arm.
  • corresponding resting means permits, that in case ofthe simplest solution the supporting position, as well as the tilting position can be fixed. In the supporting position not only a fixing by the resting means takes place, rather for instance also by the forced engagement on the box profile of the foot-arm.
  • the corresponding formation and arrangement of the filing member which fulfills a double function, in order to serve for the mounting of the table top, as well as for the holdable securing of the supporting stay-bearing pin, first of all is of advantage from the point of view of the manufacture.

  • the set screw for fixing the withdrawn position of the telescoping supporting stay serves simultaneously to this holding.
  • a rotary safety for the supporting stay in the rolling in position results, so that other additional means for such rotary securing can be omitted.
  • the overweight resulting from the crosswise projecting set screw is not in the position to rotate the supporting stay in the slided-in position. This assures also a great tilting position, which is particularly of advantage, if one deals with the one column rolling table.

  • the designed carrier Due to particularly the designed carrier, no structural part is required to be mounted separated, in order to realize the holding projection, and also a safe position thereof is assured by the unitary structure so that it is possible to bring about always safely again the interengaging holding after reaching the coaxial position of the supporting stay to the horizontal arm.
  • the opening provided above the holding projection in the carrier brings about first of all the advantage, that the holding projection does not have to stand forward too much, even ifa relatively large setting wheel is used.
  • the holding projection does not practically have to set out further, than the supporting stay projects in operating position in front of the horizontal arm.
  • the compact structure permits a solution, which brings about a control possibility to the point, that the interengagement holding of the supporting stay disposed in coaxial position to the horizontal arm is practically possible only when the set screw is disposed in tensioning position.

  • the set screw sitting at the outer telescope part of the supporting stay brings about also the advantage, that in coaxial position between the supporting stay and the horizontal arm the inner telescope part of the supporting stay can be extended, in order for instance to obtain a holding rod projecting over the table top, about as a towel rod. Due to an engaging holding, the outer telescope part remains thereby nondisplaceable in the insertion position.
  • the solution is of advantage, in which the supporting stay is displaceable in parallel position to the table column. It is brought into its supporting position, due to the coordination by longitudinal displacement to the horizontaland the foot-arm.

Abstract

A one-column table which comprises a table column telescopically variable as to its length, and a foot-arm projecting from said table column. A horizontal arm supports a table top and likewise projects from the table column to the horizontal arm. A supporting stay is coordinated for the support of the free end of the horizontal. The horizontal arm, the foot arm and the table column constitute table members. Means are provided for permitting movement of the supporting stay from a coaxial position relative to one of said members into a supporting position. The present invention relates to a one-column table with a footarm emerging from a preferably telescopic, length variable table column and an upper, horizontal arm carrying a table top and emerging likewise from the table column, to which horizontal arm is coordinated a supporting stay for the support of the free end of the horizontal arm. Such tables are first of all extremely practical, due to the asymmetric arrangement of the single table column, particularly since the table top and the which both extend in the same direction leave a large free space. On the other hand, the possibility of loading of the table top is limited as a matter of course due to the support being only at one end. A problem occurs, thereby, in case heavier objects are to be set or mounted on the table top. It has been proposed, therefore, to provide a rigid supporting stay. This solution more or less limits, however, the free space below the table top. Furthermore, such table loses its otherwise pleasant outer appearance. The universal use of the table is no longer available. It is one object of the present invention, to provide a onecolumn table which is simple as to its manufacture, advantageous as to its use and which has a structure which lends itself to loading, and to which structure the supporting stay is coordinated in a most favorable manner. It is another object of the present invention, to provide a onecolumn table, wherein the supporting stay can be brought from a coaxial position to the horizontal arm or foot-arm or to the table column into the supporting position. An advantageous structure resides in the fact, that the supporting stay can be brought, due to its length variable arrangement to the horizontal arm from a coaxial position relative to the latter into the supporting position. In accordance with the present invention, it is thereby of advantage, if the supporting stay is rollable into the hollow profile of the horizontal arm. An advantageous variation is realized in accordance with the present invention, if the supporting stay can be brought into a coaxial position laterally to the horizontal arm. A favorable design resides thereby, in accordance with the present invention in the fact, that the horizontal arm has a longitudinal slot for guidance of a holding pin of the supporting stay and has within the range of its forward end, a console or the like for the rolling of the supporting stay in its coaxial position to the horizontal arm. In order to provide a device which is simple as to manufacture, favorable to use, and first of all an optically slightly impressing device, which device assures, that the supporting stay, disposed in the coaxial position to the horizontal arm, is retained in this position, particularly in case of joltlike rolling movements of the table, it is advantageous, in accordance with the present invention, if at the free end of the horizontal arm is disposed a preferably fork-shaped holding projection for the engagement of counterholding means projecting crosswise on the supporting stay. An advantageous structure form comprises thereby, in accordance with the present invention, that the counterholding means of the supporting stay are formed by a set screw and its threaded bushing, respectively, which set screw serves the fixing of the pullout position of the telescopic supporting stay. It is favorable thereby, if, in accordance with the present invention, the fork arms of the holding projection is capable of being resiliently spread. Furthermore, it is of advantage, if, in accordance with the present invention, the holding projection sits on a carrier disposed on the bottom side of the table top and extending bushinglike into the horizontal arm, which carrier has a passage opening for the supporting stay being extendable out from the horizontal arm. A furthermore advantageous structure is given in accordance with the present invention by the fact, that the carrier has above the holding projection an opening for receiving a setting wheel of the screw. Finally, also an advantageous feature of the present invention resides in the fact that the fork arms are undercut on the inner side. Another likewise possible and advantageous solution is brought about, in accordance with the present invention, such, that the supporting stay, which is swingable from its supporting position into the coaxial position to the horizontal arm, surroundingly receives in its coaxial position the horizontal arm. An advantageous structure resides thereby, in accordance with the present invention, in the fact that the supporting stay comprises a U-profile of larger clear width, than the cross section of the horizontal arm or foot-arm, and the axle pin between the supporting stay and the arm is disposed in the range of the U arms of the supporting stay. It is favorable thereby, if the front end of the supporting stay disposed on the side of the fixing is rounded up. A furthermore advantageous design is given, in accordance with the present invention, by the fact, that the supporting stay comprises two telescopelike U-profiles extendable relative to each other and boxed into each other, the clear width of the inner of the U-profiles is larger than the cross section of the horizontal arm of the foot-arm. Furthermore, it is favorable, if, in accordance with the present invention, the horizontal arm as well as the foot-arm has resting means for receiving of counterresting means, which are provided at the free end of the supporting stay. It is of advantage thereby, if in accordance with the present invention the counter rest means of the supporting stay sit on the U-arms freely projecting over the U-stay, between which U-arms is arranged in supporting position the box-profile of the foot-arm. A further advantageous feature of the present invention resides in the fact, that on the end of the supporting stay disposed on the pivot side project the U-arms beyond the U-stay, and in the supporting position the end edge of the U-stay finds an abutment at the lower edge of the horizontal arm. Finally, it is in this connection also an advantageous feature of the present invention, that the bearing pin of the supporting stay sits in a filing member, which like a stopper is inserted into the free end of the hollow horizontal arm, and is tied down by the bearing pin in the horizontal arm and forms the projecting axle pin for the tilting movement of the table top. A further variation of the present invention resides in the fact that the supporting stay, pivotally coupled with the foot-arm, can be brought into the supporting position from a Position coaxial to the foot-arm. It is thereby of advantage, in accordance with the present invention, if the supporting stay is rollable into the hollow profile of the foot-arm. In the supporting stay which is rollable into the horizontal arm as well as in the supporting stay which is rollable into the foot-arm, a favorable feature resides, in accordance with the present invention, in the fact that the supporting stay is pivotally connected with a core member guiding itself in the foot-arm or in the horizontal arm, which core member finds an abutment in the pulled out end position on a stop of the arm. Thereafter, it is of advantage, in accordance with the present invention, if the supporting stay finds an abutment in its supporting position at the end face of the arm.
Furthermore it is advantageous in case of a rolling in supporting stay, in accordance with the present invention, if the supporting stay is equipped at the other end with a shoe, which steps into engagement at the opposite arm of the table. In accordance with the present invention, the inter-engaging connection between shoe and arm for example, in form of a rest or pin engagement is of advantage. A favorable structure in accordance with the present invention is also realized thereby such, that the core member is rotatably disposed in the arm. Also in case of these solutions, in accordance with the present invention it is favorable, if a telescopelike extendibility of the supporting stay is present and a set screw is coordinated to the outer supporting stay part pivoted to the core member at the end side and the shoe sits at the inner supporting stay part. Furthermore a favorable structure resides, in accordance with the present invention, in the arrangement according to which, the shoe engages in supporting position the table top-supporting angle of the horizontal arm. A further advantageous variation resides, in accordance with the present invention, in the fact, that the latch-shaped, flat supporting stay pivoted tiltably to the one wide side of the foot-arm has at its free end a shoe with two entrance openings, which are perpendicular relative to each other and of which one opening serves for the supporting entrance of the horizontal arm and the other opening for the entrance of the foot-arm in the coaxial position between the foot-arm and the supporting stay. A favorable design resides hereby, in accordance with the present invention, such, that the latch-shaped supporting stay comprises two stay parts guided relative to each other by way of a longitudinal slot and capable of being extended relative to each other, whereby the stay part disposed outwardly has at the transformation to the shoe a crank arrangement directed towards the foot-arm. Finally in accordance with the present invention, a solution also is possible, according to which the supporting stay due to a longitudinally displaceable arrangement to the foot-arm and to the horizontal-arm can be brought from its position parallel to the table column into the supporting position. In accordance with the present invention, it is thereby of advantage, to provide longitudinal guides, preferably slot guides, for the supporting stay ends at the horizontal-arm and at the foot-arm. It is also favorable thereby, in accordance with the present invention, if the supporting stay is extendable telescopelike and the set screw for the capability of being telescoped is disposed on the side of the supporting stay remote from the table column.

ONE-COLUMN TABLE The present invention relates to a one-column table with a foot-arm emerging from a preferably telescopic, length variable table column and an upper, horizontal arm carrying a table top and emerging likewise from the table column, to which horizontal arm is coordinated a supporting stay for the support of the free end of the horizontal arm.
Such tables are first of all extremely practical due to the asymmetric arrangement of the single table column, particularly since the table top and the which both extend in the same direction leave a large free space.
On the other hand, the possibility of loading of the table top is limited as a matter of course due to the support being only at one end. A problem occurs, thereby, in case heavier objects are to be set or mounted on the table top. It has been proposed, therefore, to provide a rigid supporting stay.
This solution more or less limits, however, the free space below the table top. Furthermore, such table loses its otherwise pleasant outer appearance The universal use of the table is no longer available.
It is one object of the present invention, to provide a onecolumn table which is simple as to its manufacture, advantageous as to its use and which has a structure which lends itself to loading, and to which structure the supporting stay is coordinated in a most favorable manner.
It is another object of the present invention, to provide a one-column table, wherein the supporting stay can be brought from a coaxial position to the horizontal arm or foot-arm or to the table column into the supporting position.
An advantageous structure resides in the fact, that the supporting stay can be brought, due to its length variable arrangement to the horizontal arm from a coaxial position relative to the latter into the supporting position.
In accordance with the present invention, it is thereby of ad vantage, if the supporting stay is rollable into the hollow profile of the horizontal arm.
An advantageous variation is realized in accordance with the present invention, if the supporting stay can be brought into a coaxial position laterally to the horizontal arm.
A favorable design resides thereby, in accordance with the present invention in the fact, that the horizontal arm has a longitudinal slot for guidance of a holding pin of the supporting stay and has within the range of its forward end, a console or the like for the rolling of the supporting stay in its coaxial position to the horizontal arm.
In order to provide a device which is simple as to manufacture, favorable to use, and first of all an optically slightly impressing device, which device assures, that the supporting stay, disposed in the coaxial position to the horizontal arm, is retained in this position, particularly in case ofjoltlike rolling movements of the table, it is advantageous, in accordance with the present invention, if at the free end of the horizontal arm is disposed a preferably fork-shaped holding projection for the engagement of counterholding means projecting crosswise on the supporting stay. An advantageous structure form comprises thereby, in accordance with the present invention, that the counterholding means of the supporting stay are formed by a set screw and its threaded bushing, respectively, which set screw serves the fixing of the pullout position of the telescopic supporting stay. It is favorable thereby, if, in accordance with the present invention, the fork arms of the holding projection is capable of being resiliently spread. Furthermore, it is of advantage, if, in accordance with the present invention, the holding projection sits on a carrier disposed on the bottom side of the table top and extending bushinglike into the horizontal arm, which carrier has a passage opening for the supporting stay being extendable out from the horizontal arm. A furthermoreadvantageous structure is given in accordance with the present invention by the fact, that the carrier has above the holding projection an opening for receiving a setting wheel of the screw. Finally, also an advantageous feature of the present invention resides in the fact that the fork arms are undercut on the inner side.
Another likewise possible and advantageous solution is brought about, in accordance with the present invention, such, that the supporting stay, which is swingable from its supporting position into the coaxial position to the horizontal arm, surroundingly receives in its coaxial position the horizontal arm. An advantageous structure resides thereby, in accordance with the present invention, in the fact that the supporting-stay comprises a U-profile of larger clear width, then the cross section of the horizontal arm or foot-arm, and the axle pin between the supporting stay and the arm is disposed in the range of the U arms of the supporting stay. It is favorable thereby, if the front end of the supporting stay disposed on the side, of the fixing is rounded up. A furthermore advantageous design is given, in accordance with the present invention by the fact, that the supporting stay comprises two telescopelike U-profiles extendable relative to each other and boxed into each other, the clear width of the inner of the U- profiles is larger than the cross section of the horizontal arm of the foot-arm. Furthermore, it is favorable, if, in accordance with the present invention, the horizontal arm as well as the foot-arm has resting means for receiving of counterresting means, which are provided at the free end of the supporting stay. ltis of advantage thereby, if in accordance with the presentinvention the counter rest means of the supporting stay sit on the U-arms freely projecting over the U-stay, between which U-arms is arranged in supporting position the box-profile of the foot-arm.
A further advantageous feature of the present invention resides in the fact, that on the end of the supporting stay disposed on the pivot side project the U-arms beyond the U- stay, and in the supporting position the end edge of the U-stay finds an abutment at the lower edge of the horizontal arm. Finally, it is in this connection also an advantageous feature of the present invention, that the bearing pin of the supporting stay sits in a filing member, which like a stopper is inserted into the free end of the hollow horizontal arm, and is tied down by the bearing pin in the horizontal arm and forms the projecting axle pin for the tilting movement of the table top.
A further variation of the present invention resides in the fact that the supporting stay, pivotally coupled with the footarm, can be brought into the supporting position from a position coaxial to the foot-arm. It is thereby of advantage, in accordance with the present invention, if the supporting stay is rollable into the hollow profile of the foot-arm.
In the supporting stay which is rollable into the horizontal arm as well as in the supporting stay which is rollable into the foot-arm, a favorable feature resides, in accordance with the present invention, in the fact that the supporting stay is pivotally connected with a core member guiding itself in the foot-arm or in the horizontal arm, which core member finds an abutment in the pulled out end position on a stop of the arm. Thereafter, it is of advantage, in accordance with the present invention, if the supporting stay finds an abutment in its supporting position at the end face of the arm.
Furthermore it is advantageous in case of a rolling in supporting stay, in accordance with the present invention, if the supporting stay is equipped at the other end with a shoe, which steps into engagement at the opposite arm of the table. In accordance with the present invention, the inter-engaging connection between shoe and arm for example, in form of a rest or pin engagement is of advantage.
A favorable structure in accordance with the present invention is also realized thereby such, that the core member is rotatably disposed in the arm.
Also in case of these solutions, in accordance with the present invention it is favorable, if a telescopelike extendibility of the supporting stay is present and a set screw is coordinated to the outer supporting stay part pivoted to the core member at the end side and the shoe sits at the inner supporting stay part.
Furthermore a favorable structure resides, in accordance with the present invention, in the arrangement according to which, the shoe engages in supporting position the table topsupporting angle of the horizontal arm.
A further advantageous variation resides, in accordance with the present invention, in the fact, that the latch-shaped, flat supporting stay pivoted tiltably to the one wide side of the foot-arm has at its free end a shoe with two entrance openings, which are perpendicular relative to each other and of which one opening serves for the supporting entrance of the horizontal arm and the other opening for the entrance of the foot-arm in the coaxial position between the foot-arm and the supporting stay.
A favorable design resides hereby, in accordance with the present invention, such, that the latch-shaped supporting stay comprises two stay parts guided relative to each other by way of a longitudinal slot and capable of being extended relative to each other, whereby the stay part disposed outwardly has at the transformation to the shoe a crank arrangement directed towards the foot-arm.
Finally in accordance with the present invention, a solution also is possible, according to which the supporting stay due to a longitudinally displaceable arrangement to the foot-arm and to the horizontal-arm can be brought from its position parallel to the table column into the supporting position. ln accordance with the present invention, it is thereby of advantage, to provide longitudinal guides, preferably slot guides, for the supporting stay ends at the horizontal-arm and at the foot-arm.
It is also favorable thereby, in accordance with the present invention, if the supporting stay is extendable telescopelike and the set screw for the capability of being telescoped is disposed on the side of the supporting stay remote from the table column. Also it is favorable, in accordance with the present invention, if the supporting stay is locked in the supporting position, preferably due to upwardly angularly disposed rest recesses at the foot-arm and at the horizontalarm for the entrance of the supporting stay guide-bolts. An advantageous structure is in this connection, in accordance with the present invention, realized such, that at least at the horizontal arm an upwardly directed resting recess for the entrance of the supporting stay guide-bolts is provided. Finally an advantageous feature is given in accordance with the present invention by the arrangement, according to which the supporting stay ends surround in forklike manner the horizontal arm and the foot-arm with the formation of a sliding guide shoe.
Due to such design, a one-column table of increased value as to use is produced. Its manufacture is relatively simple, and its outer appearance is not disfigured. First of all, the supporting stay can be brought into a hiding position in case of nonuse.
If the supporting stay is not required for the additional support of the table plate or the table top, it can be completely taken out of view into a hiding position, either into the horizontal arm present in the form ofa box profile or laterally thereto in equal direction extension, either by rolling into the foot-arm, tilting against the foot-arm or displacing of the stay into coaxial position to the table column. The supporting stay remains however always without fail at the table.
Due to the structural arrangement, the supporting stay itself can be formed telescopically expandible, and is capable of fulfilling this task in each set height position of the table top. The danger does not exist, that the supporting stay in case of requirement is displaced at that moment. Even in supporting position, the full freedom for the legs of the user is retained in most solutions in spite of the exercise of a good supporting function. A favorable withdrawal extension limit for the desired impossibility of losing the stay is obtained. The supporting stay in coaxial position to the foot-arm brings about a favorable displacement of the gravity center of the onecolumn table, thereby increasing the standing stability. The telescopelike adjustability of the two supporting stay profile assures, that the supporting stay can always be shortened for a length, which corresponds at the most with the length of the arm. The provision of corresponding resting means permits, that in case ofthe simplest solution the supporting position, as well as the tilting position can be fixed. In the supporting position not only a fixing by the resting means takes place, rather for instance also by the forced engagement on the box profile of the foot-arm. To make the U-stay of the supporting stay an abutment, brings about an appreciable simplification of use and increased stability of use for the supporting position. The corresponding formation and arrangement of the filing member, which fulfills a double function, in order to serve for the mounting of the table top, as well as for the holdable securing of the supporting stay-bearing pin, first of all is of advantage from the point of view of the manufacture. The particular holding of the supporting stay rolled into the horizontal arm is likewise of advantage. The set screw for fixing the withdrawn position of the telescoping supporting stay serves simultaneously to this holding. In addition also a rotary safety for the supporting stay in the rolling in position results, so that other additional means for such rotary securing can be omitted. The overweight resulting from the crosswise projecting set screw is not in the position to rotate the supporting stay in the slided-in position. This assures also a great tilting position, which is particularly of advantage, if one deals with the one column rolling table. The capability of resilient spreading of the fork arms also contributes for the tilting freedom and favorable holding. Due to particularly the designed carrier, no structural part is required to be mounted separated, in order to realize the holding projection, and also a safe position thereof is assured by the unitary structure so that it is possible to bring about always safely again the interengaging holding after reaching the coaxial position of the supporting stay to the horizontal arm. The opening provided above the holding projection in the carrier brings about first of all the advantage, that the holding projection does not have to stand forward too much, even ifa relatively large setting wheel is used. The holding projection does not practically have to set out further, than the supporting stay projects in operating position in front of the horizontal arm. In particular the advantage occurs, that the compact structure permits a solution, which brings about a control possibility to the point, that the interengagement holding of the supporting stay disposed in coaxial position to the horizontal arm is practically possible only when the set screw is disposed in tensioning position. One has achieved thereby, that the lower, telescopable part of the supporting stay is immovable and does not move out in turn in case of rattling or rolling movements of the table from the other telescope part of the supporting stay. The undercut inner sides permit in case of the small necessary spring strokes of the fork arms, the achievement of a sufficiently large holding force. The set screw sitting at the outer telescope part of the supporting stay brings about also the advantage, that in coaxial position between the supporting stay and the horizontal arm the inner telescope part of the supporting stay can be extended, in order for instance to obtain a holding rod projecting over the table top, about as a towel rod. Due to an engaging holding, the outer telescope part remains thereby nondisplaceable in the insertion position. Also the solution is of advantage, in which the supporting stay is displaceable in parallel position to the table column. It is brought into its supporting position, due to the coordination by longitudinal displacement to the horizontaland the foot-arm. In its end-side supporting position no limitationv of the free space between the footand the horizontal-arm takes place. It is, however, also possible that the supporting stay assumes any selected intermediate position between the supporting position and the parallel engaging position. In the engaging position of the supporting stay on the table column the supporting stay adjusts itself favorably into the total structure form. It is there particularly optically not too readily visible. This particular coordination of the supporting stay to slots of the horizontaland foot-arms holds also the latter again at the table without loss. Due to the structural measure, the supporting stay can be designed telescopically extendible, and particularly simple resting means for securing the supporting stay in its end-side, operative position can be chosen. The longitudinal slots of the foot-arm and of the horizontal arm form merely upwardly directed rest recesses,
into which the supporting stay guide-bolts enter. At the horizontal arm at least one upwardly directed resting recess is provided, which brings about the advantage, that loads of the table top favor the entrance of the supporting stay and can also be brought into diagonal effective position, and in particular then, for example, if no person sits at the table and the latter serves only for the support of a heavier object as for instance a television receiver. The guide shoes provided at the ends of the supporting stay surround the horizontal-arm and the foot-arm in forklike manner and increase the total stability of the one-column table. Furthermore, the guide shoes serve also for the reception of the supporting stay guide-bolts. With these and other objects in view, which will become apparent in the following detailed description, the present invention, which is shown by example only, will be clearly understood in connection with the accompanying drawings, in which:

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 formedtelescopically. 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 extensionconstituting 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-coluinn 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 I9 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 ofthe 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 ofa 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 offof 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 ofa 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 ofa console in form ofa cup 31. In order to put the supporting stay into operative position, it is merely required, to lift the supporting stay within the range ofthis 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. l4-l7 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 ofan 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. [7), 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 form view all of the seeing 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 I4 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 new 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 ann I0. This assumed tiltedposition (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 sue of a nontelescopic supporting stay directly on the mentioned sidewall of the horizontal arm 10.
