Definitions

  • the invention relates to a variable table with a table top consisting of composite table elements, with table legs arranged on the undersides of the table elements and with connecting members for the table top plate elements.
  • the object is achieved in that rectilinear guide channels are provided on the underside of the plate elements, that the connecting links separately as straight, in the guide channels insertable and longitudinally displaceable connecting rods are formed, and that the plate elements have locking members for locking the connecting rods in the guide channels and stabilizing the table.
  • variable table 1 shown in Fig. 1 consists of two semicircular plate elements 2 and 3, which are joined together along a circle diameter with the help of connecting links to be described.
  • Table legs 4, 5, 6, 7 are arranged on the plate elements 2, 3.
  • the guide channels 9, 11 are formed on most of their longitudinal extent as a completely closed tunnel and have a rectangular inner cross-sectional profile.
  • the connecting rods 13, 14 are designed as metal tubes and have a rectangular outer cross-sectional profile, which corresponds to the inner cross-sectional profile of the guide channels, so that the connecting rods are longitudinally displaceable in the guide channels.
  • the guide rods 13, 14 are designed as separate parts which can be inserted into the guide channels 9, 11 and can be removed from them.
  • the connecting rods 13, 14, which are inherently displaceable in the guide channels 9, 11, can be locked in certain positions by locking members.
  • This lock also serves to stabilize the table composed of several plate elements.
  • a clamping claw 15 is provided, which is fastened with a screw 16 to the plate element 2 and with its free end 17 presses against a flat side of the connecting rod 13, so that it is prevented from moving. After loosening the screws 16, the connecting rod 13 can be moved, brought into a new position and in turn can be fixed there by the claw 15.
  • a toggle 19 is pivotally mounted on a pin 18 provided on the plate element 2, which in a conventional manner has a pressing surface 21 which is arranged eccentrically to the pin 18 and with which it can be pressed against a flank of the connecting rod 14 .
  • the connecting rod 14 can thus be fixed in the guide channel 11 by correspondingly pivoting the toggle 19. After loosening the toggle 19, the rod 14 can be moved, brought into a new position and locked there again by pivoting the toggle 19. (See also Fig. 10).
  • each plate element 2 On the straight side 12 of each plate element 2, 3 projecting pins 22, 23 are formed, which fit into corresponding recesses 24 and 25 of an adjacent plate element (see also Fig. 4).
  • the table legs 4 to 7 are first screwed to the respective plate elements 2, 3. Subsequently, two connecting rods 13, 14 are inserted into the guide channels 9, 11 of one plate element 2 and locked there by means of the locking members 15 or 19 that they protrude a bit beyond the straight side 12, at least to the extent that they are separated from the Locking elements 15 or 19 of an adjacent plate element can be detected. Now the two plate elements 2, 3 by inserting the protruding pieces of the connecting rods 13, 14 in the guide channels in question are joined and firmly connected to one another by actuating the locking members, so that the circular table shown in FIG. 1 results.
  • the circular table according to FIG. 1 can be transformed into an approximately oval table according to FIG. 2 by inserting a rectangular plate element 26 between the plate elements 2 and 3.
  • 5 shows the underside of the rectangular plate element 26, on which in turn guide channels 27, 28 are provided for receiving the connecting rods 13, 14.
  • the guide channels 27, 28 are not closed in the manner of a tunnel all around, but rather are designed as channels which are open downwards over their entire longitudinal extent.
  • the rectangular plate element 26 can be easily inserted and removed between two correspondingly widely spread plate elements 2, 3 connected by the connecting rods 13, 14.
  • locking elements in the form of the claws 15 can also be provided on the underside of the plate element 26 (FIG. 5), which fix the plate element 26 relative to the rods 13, 14 lock, which in turn are determined by the locking elements 15 or 19 provided on the plate elements 2, 3.
  • the connecting rods 13, 14 advantageously have a length such that they from the 1 completely fill the guide channels 9, 11 on both plate elements 2, 3 and - as shown in Fig. 3 - extend approximately to the circular edge of these elements.
  • the connecting rods 9, 11 are long enough to be able to pull apart the two plate elements 2, 3 as shown in FIG. 2 for the purpose of inserting the rectangular plate element 26, but both connecting rods 9, 11 by the locking elements 19 on both plate elements 2 , 3 can still be locked.
  • the tunnel-like closed guide channels 9, 11 have longitudinal slots 29 on their undersides.
  • resilient locking elements 31 are provided, the construction of which can be seen in FIG. 9.
  • the internally hollow connecting rods 13 have holes 32 near their ends, in which cylindrical locking pins 33 are inserted.
  • the locking pins 33 are firmly connected on their rear side to one leg 34 of a V-shaped spring 35, the other leg 36 of which is supported on the inner wall of the connecting rod 13 opposite the bore 32.
  • the locking pin 33 is resiliently held within the bore 32 and can be pressed so far into the interior of the rod 13 that its top is flush with the outside of the connecting rod 13.
  • the connecting rod 13 When the locking pin 33 is pressed in, the connecting rod 13 can be inserted into the associated Guide channel 9 are inserted. After a correspondingly long insertion, the locking pin 33 snaps out again in the area of the longitudinal slot 29, so that the connecting rod 13 is now displaceable in the area of the longitudinal slot 29, but is prevented from being pulled out of its guide channel as long as the locking pin 33 is not pressed in again.
  • the two locking pins 31 of the guide rods 9, 11 assume the position shown in FIG. 3 at one end of the longitudinal slots 29.
  • the two locking pins 31 abut the opposite (lower in FIG. 3) ends of the longitudinal slots 29.
  • connection rods 13, 14 are normally not sufficient. These rods must therefore be extended by attaching extension elements, as shown in Fig. 11.
  • An extension element 37 in the form of a metal tube with a rectangular cross section has at its one end a likewise tubular projection 38 of rectangular cross section. The size of the cross section of the projection 38 on the extension element 37 is selected so that the projection 38 fits snugly into the connecting rod 13 to be extended.
  • a resilient locking pin 33 is provided in the projection 38, which corresponds in structure and mode of operation to the locking pin 33 according to FIG. 9.
  • the verb Extension rod 13 has at its front end a bore 39 (FIGS. 9 and 11) into which the locking pin 33 snaps into the connecting rod 13 when telescoping the projection 38. In this way, the connecting rod 13 can be extended by the extension element 37.
  • the extension element 37 is designed at its end opposite the locking pin 33 (not shown in FIG. 11) as well as the connecting rod 13 according to FIG. 11, so that it can be extended by a further extension element 37.
  • a total of connecting rods of any length can be produced, which in turn enable the design of tables in a wide variety of variations.
  • FIG. 13 schematically shows a table with an essentially rectangular cross section, which is composed of two rectangular plate elements 26 and two narrower, rectangular end pieces 41 using corresponding connecting rods, indicated by dashed lines in FIG. 13.
  • 6 shows a bottom view of the connection of an edge piece 41 to a plate element 26.
  • pins 22, 23 are again provided, which engage in corresponding recesses 24 and 25, respectively.
  • tunnel-like closed guide channels 42, 43 are provided, into which the ends of connecting rods 13, 14 can be inserted. Gags 19 allow the connecting rods 13, 14 to be locked in the guide channels 42, 43.
  • screw bushings 8 are provided for fastening table legs 4, 5.
  • the arrangement of these screw bushings is such that two bushings are provided on the plate element 26 and on the edge piece 41, respectively.
  • the screwed table leg bridges the butt joint between plate element 26 and edge piece 41 and contributes to the firm connection of these parts. Even with two abutting plate elements 26, a screwed table leg would bridge the two elements.
  • leveling screws 44 are provided, via which the table leg rests on the floor. These leveling screws allow the effective table leg length to be changed so that the table can be set up with a horizontal table top without wobbling. 7 and 8, the design and operation of a leveling screw 44 is shown.
  • the leveling screw 44 comprises a threaded shaft 45 and a screw head 46.
  • the shaft 45 is screwed into a nut 47 provided with a corresponding internal thread, which in turn is firmly connected to the lower end of the table leg 6.
  • a thread-free collar 48 provided at the free end of the shaft 45 prevents the leveling screw 44 from being unscrewed from the nut 47.
  • the screw 44 is thus captively connected to the table leg.
  • the nut 47 consists of two half-shells 49, 51 enclosing the shaft, which have locking lugs 52 at their ends facing the table leg 6.
  • a chamber is provided at the lower end of the table leg 6, which has an opening 53 adapted to the catch 52 in its bottom.
  • a slot 54 provided between the locking lugs at the end of the half-shells 49, 51 gives the locking lugs 52 a resilient character.
  • the two half shells 49, 51 are injection molded from plastic.
  • the two half-shells 49, 51 can be connected to one another by a so-called plastic film hinge.
  • the two half shells 49, 51 of the nut 47 are first placed around the shaft 45 of the screw 44.
  • the half-shells with the enclosed threaded shaft are then introduced into the chamber mentioned in such a way that the latching noses penetrate the opening 53 in the bottom of the chamber and then snap behind the bottom. This fixes the whole arrangement on the table leg.
  • An inner ring web 55 in the nut 47 interacts with the collar on the shaft 48 of the screw 44 and prevents the screw 44 from being completely unscrewed from the nut 47.
  • the semicircular plate elements 2 the rectangular plate elements 26 and the edge pieces 41 are also sector-shaped plate elements 56.
  • These sector-shaped elements 56 are each delimited by two straight sides 12 enclosing an angle of 45 ° and by two arcs 57, 58 of different radii.
  • the length of the straight sides 12 corresponds to the length of the straight sides 12 of the semicircular plate element 2 and the longer side of the plate elements 26.
  • FIG. 14 shows a multi-curved table, with two arms 59, 61 running at right angles to one another and a further, straight arm 62 which encloses an angle of 135 ° with arm 61. Between the arms 59, 61 two, between the arms 61 and 62 a sector-shaped plate element 56 are arranged.
  • 15 shows a large oval table, the rounded sides of which are each formed by four sector-shaped plate elements 56. 15 has a central recess 63.
  • the undersides of the sector-shaped plate elements 56 like the undersides of the semicircular and rectangular plate elements 2, 26 according to FIGS. 3 and 6, are formed, that is to say they are essentially provided with guide channels for connecting rods, the connecting rods in turn being held in the guide by locking members channels can be locked.
  • the course of the guide channels and the connecting rods is indicated by dashed lines in FIGS. 14 and 15.
  • the guide channels on the sector-shaped plate elements 56 each run perpendicular to the straight sides 12. They can also cut within a plate element 56 - as indicated in area D in FIG. 14 - in order to accommodate longer connecting rods in this way.
