Definitions

  • the invention relates to a frame for tables, mobile office trolleys and the like with several steep, preferably substantially vertically arranged frame legs.
  • Tables are already known which have a height adjustment arranged on a table leg, it being possible, by rotating movements, to extend or shorten the table leg as required and thus to adapt the frame of the table to the unevenness of the floor. In order to get a firm footing, the height must be precisely adjusted by hand and readjusted when the table is moved.
  • the invention has set itself the task of providing a device that is simple and inexpensive to manufacture, in which the length of the frame legs without such a rather cumbersome adjustment is achieved by the weight of the frame or table or by spring pressure changes and is thus quickly and conveniently adapted to unevenness in the floor.
  • a frame of the type mentioned according to the invention in that at least one of these legs is divided and consists of at least two telescopically displaceable parts and one of these two parts is displaceable relative to the other part against the force of a counter-pressure-supplying pressure element .
  • the telescopically displaceable parts of two adjacent frame legs are coupled by coupling members such that when the telescopically displaceable part of one frame leg is shifted upward, the telescopically displaceable part of the other adjacent frame leg is inevitably displaced in the opposite direction becomes.
  • a locking device is provided in a preferred embodiment, the actuation of which fixes the respective position of the telescopically displaceable parts and prevents further displacement.
  • Figures 1 to 4 show a garden table designed according to the invention and its structural details.
  • the table has a table top 2, which is supported by a frame 3, which has four structurally connected frame legs 4A, 4B, 4C and 4D.
  • the frame legs consist of tubes, namely that two adjacent frame legs 4A and 4B or 4C and 4D form a structural unit which is formed from a tube bent twice.
  • the tubular bolt 7 and the balls 9 serve as coupling links and have the purpose of coupling the telescopically displaceable parts 5A and 5B to one another in such a way that if the telescopically displaceable part 5A is pressed upward into the frame leg 4A, for example due to a particular weight load, 5B is correspondingly pushed out of the frame leg 4B.
  • a helical spring 10 between the intermediate piece 6 and the upper end face of the telescopically displaceable part 5A.
  • This helical spring is shown schematically simplified in FIG.
  • the coil spring is designed in such a way that the adjacent coil turns touch or almost touch.
  • tubular bolt 7 it is also possible to omit the tubular bolt 7 and to fill the entire cavity between the mutually facing upper end faces of the telescopically displaceable parts 5A and 5B with balls 9 acting as coupling elements or with helical spring 10 acting as coupling elements.
  • the locking device can consist of a clamping lever 14 which can be pivoted about the axis 13 and which is brought into such a position by means of the actuating lever 15 that its end, which has an eccentric limiting surface 17, is firmly against a flattened point 19 of the in the intermediate piece 6 slidably mounted pin 7 is pressed. In this position, the intermediate piece 6 is then locked against longitudinal displacement, and the coupling elements, for example the balls 9, are then no longer displaceable in the longitudinal direction of the tube surrounding them.
  • Figure 5 shows another embodiment of an adjustable frame leg.
  • the telescopically displaceable in the longitudinal direction part 5'A carries on its inside a pipe 2i, for example fastened by means of a weld seam, which can be pushed into the inside of the pipe 22 forming the upper part of the frame leg.
  • the outer diameter of the part 5A and the tube 22 are the same.
  • the tube 22 carries on its outside at point 23 a fastened sleeve 24 T.
  • Figures 6, 7 and 8 show another embodiment of a table designed according to the invention, in which the telescopically displaceable parts 5A and 5B are coupled to one another by means of a Bowden cable 26 such that when one of the two parts 5A and 5B is pushed in, the other part is pressed out .
  • the movement of the Bowden cable can be blocked by means of a locking device 12A.
  • Figures 6 and 7 show construction details of this blocking device.
  • the core 26 1 of the Bowden cable 26 is blocked in the normal state by the force of the spring 27 by means of a fitting 29 against longitudinal displacement.
  • the lock is released against the force of the spring 27, and when the lock is released, the frame legs or their telescopically mounted parts can be adapted to the unevenness of the floor.
  • FIG. 9 shows an embodiment of a table designed according to the invention with four frame legs, which differs from the embodiment shown in FIG. 1 by the other embodiment of the locking device.
  • the locking device 12B essentially consists of two projecting pins 31, which prevent movement of these coupling members in the longitudinal direction of the tube through an opening in each of the tubes enclosing the coupling members 9.
  • the coupling links are shown as balls 9, but other coupling links can also be used, for example the helical spring 10 shown on the left in FIG. 2.
  • the table top 2 is against the frame by a central piece 32 against the force by a small angular amount of pressure springs, not shown in the figure, pivotally mounted. If the table top is in the above one of the Pin 31 lying area loaded, then it is pivoted somewhat about the center piece 32 and the relevant pin 31 thereby pressed onto the coupling links or between the coupling links and thereby reliably prevents a longitudinal displacement of the coupling links.
  • FIG. 10 shows such an embodiment of a frame 3, specifically with four telescopically displaceable parts 5A, 5B, 5C, 5D. These parts are connected to one another via hydraulic lines 34, if appropriate with the interposition of corresponding cylinders, such that when a telescopically displaceable part is pushed in due to greater weight loading, the other telescopically displaceable parts ip are pushed out to such an extent that the parts 5A, 5B , 5C and 5D is the same pressure applied to the pad.
  • the locking device is designed as a valve 35. If the hydraulic lines 34 leading to the individual parts 5A, 5B, 5C, 5D are closed or the connection of two hydraulic lines leading to the individual telescopically displaceable parts 5A, 5B, 5C, 5D is interrupted by actuation of this locking device, the frame also remains eccentric Weight load unchanged at its location.
  • FIG. 11 shows an embodiment of a frame leg, which is applicable to both three-legged and multi-legged Racks is applicable.
  • the part 5A which is mounted telescopically in the frame leg 4A can be pushed into the frame leg 4A against the pressure element 36 which is designed as a compression spring.
  • the position of the telescopically displaceable part 5A can be fixed in the frame leg 4A by means of the locking device 12.
  • the locking device has an eccentric 37 which, in the locking position, presses directly on the displaceable part 5A directly or via a part of the frame leg 4A designed as a movable tongue.
  • a spring 39 is provided which holds the locking device in the locked state; however, the pressure can be released at any time by pressing the actuating lever 40, in particular for adjusting the position of the table.
  • a frame leg 4A is shown in FIG. 12 as a further constructive possibility, the telescopically mounted part 5A of which can be pushed in against the force of a pressure element 36 designed as a spring and contains a locking device which can be released optionally by means of a Bowden cable 41.
  • a pressure element 36 designed as a spring and contains a locking device which can be released optionally by means of a Bowden cable 41.
  • the force of the spring 42 presses an expansion piece 43 against the beveled surfaces of an expandable member 44 connected to the part 5A, and this member is thereby pressed against the inner wall of the frame leg 4A. This fixes the position of the telescopically displaceable part 5A in the frame leg 4A.
  • FIG 13 shows schematically, greatly simplified, another embodiment of the frame, in which the telescopically displaceable lower parts of the frame legs are coupled by means of a coupling member that is subjected to tension such that when a lower part is pushed in by pressure, the other lower part on the associated tube in Is pulled out downwards.
  • the two frame legs 4A and 4B each have a lower part 5A and 5B which can be telescopically pushed in and which have slot-like openings 50 running in the longitudinal direction of the legs.
  • a horizontal bolt 51 the ends of which are fastened to the frame legs 4A and 4B, projects through these openings.
  • a flexible coupling member 52 is guided around these two bolts 41 in the manner shown in the figure, both ends of which are fastened to the hooks 51 which are arranged in the interior of the frame legs 4A and 4B.
  • the flexible coupling link is expediently designed as a wire rope, but it can also be designed as a chain or as a plastic rope.
  • the twice bent pipe shown in FIGS. 1, 2 and 9 can be replaced by two once bent pipes.
  • the coupling members for example balls, located in the interior of the two tubes, in particular in the interior of the curved parts of these two tubes, are coupled by an axially displaceable bolt 7 which is not covered on the outside.
