Definitions

  • the present invention relates to a height-adjustable table frame according to the preamble of the independent claims.
  • Such a table frame has become known from EP-A1 130 264, in which a crank mechanism is provided, to which the legs of the table frame are connected at one end by means of a rotating chain.
  • the table frame can be raised from the minimum to the maximum position by turning the crank.
  • These two end positions can be locked, but only in the direction of the extreme positions.
  • a lock for the continuous movement of the table frame from one extreme position to the other is not provided.
  • the stepless adjustability of each position ensures a universal application, but is not always desirable and increases the manufacturing costs not insignificantly.
  • the invention is therefore based on the object of creating a table frame that can be moved between two preselectable extreme positions and can be locked in position in each of these positions.
  • the table is preferably used as a camping table in its maximum position and as an extension of a bed in its minimum position.
  • the table frame according to FIG. 1 has a table top 1, the upper side 2 of which is used for placing objects, and the actual table frame 4 is fastened to the underside 3 thereof.
  • the table frame 4 consists essentially of a drive housing 5, two legs 6 and 7 and each a traverse 8 and 9, which form the foot of the leg.
  • the legs are Y-shaped; the two legs 10 and 11 are connected to one another at the pivot point 12 and the leg 10 is mounted on the drive housing 5 via a further pivot point 13.
  • the trunk 14 forming the extension of the leg 11 carries the crossmember 8 and 9 at its lower end.
  • the free ends 15 and 16 of the legs 11 of both legs 6 and 7 are connected with an endless rope, for example, which enables the logs to run in unison 14 causes that runs in the drive housing 5 in a plane approximately parallel to the table top 1.
  • the stops 17 to 19 of this are visible in FIG. Of these, the stops 17 and 18 interact with the free end 15 of the leg 6 and define the minimum position 20.
  • the maximum position 21 is reached when the free end 15 moves against the stop 19.
  • the stops 18 and 19 are adjustably mounted on a shaft 22, they can both be adjusted in the direction of the double arrow 23. Moving the stop 19 to the left means a higher maximum position, to the right a lower one. The same applies to the stop 18 for the minimum position. When moving this stop, the associated stop 17 must also be adjusted.
  • the stops are positioned with respect to an extreme position so that the associated leg end can only be moved in the extreme position with very little play.
  • the shaft 22 is connected to a lever 24 to pivot the shaft and thus the stops 18 and 19 except Bring engagement from the free end 15.
  • the stop 17 and the fourth stop (not visible in FIG. 1) are fastened to the drive housing 5.
  • the drive housing 5 is formed from two bodies 26 which are rigidly connected to one another via two connecting profiles 27 with a C-shaped cross section.
  • the opening slots 28 of the connecting profiles face away from each other.
  • the rope 29 is guided in them, cf. Fig. 3, which is supported by two deflection rollers 30, which are located in one of the bodies.
  • the bodies 26 also support the shaft 22 or the lever 24 in bores 31.
  • the fourth stop 25 is clearly visible from this figure.
  • FIG. 3 shows a section through one of the bodies 26.
  • the fulcrums 13 for the legs 10 of the Y-shaped legs are provided on the outside of the body 26.
  • Each leg 10 is designed as a double leg 10, which unite at the pivot point 12.
  • the shaft 22 carries, via a screw connection 32, the stop 18 which interacts with a pin 33 which is assigned to the free end 15 and at the same time serves as a connection of this end to the cable 29.
  • a stop part 34 is connected to the shaft 22, the nose 35 of which forms a rotation angle limiter with the upper side 36 of the body 26.
  • Another nose 37 limits the pivoting angle of the stop member 34 with a surface of the body 26 in the other direction.
  • Stop part 34, shaft 22 and lever 24 are pretensioned by a tension spring 38 suspended between stop part 34 and a point 39 of the body 26 in such a way that the nose 35 rests on the upper side 36. So that the stop 18 is pivoted into the path of the pin 33.
  • two U-shaped brackets 40 are inserted into openings 41 of both bodies 26 of the drive housing 5, which can be fixed by means of clips 42 on the underside 3 of the table top 1 when the table is used in the maximum position. If it is moved from this into the minimum position, the brackets 40 are removed from the clamps 42 solved, whereby they fall due to the action of gravity in the position shown in FIG. 5.
  • a fork 43 is provided which is dimensioned such that it partially encompasses the outer circumference of the crossmember 8 or 9 in the minimum position. This means that the table top is also supported directly via the brackets.
  • tension springs 44 can be provided, which are hooked on the one hand, for example, to the axes of the deflection rollers 30 within the drive housing 5, and on the other hand to the free ends 15 and 16 and are tensioned when the table is in the minimum position is pressed. The table can then easily be moved to the maximum position by relieving the tension springs.
  • the stops 17 and 25 are moved in the connecting profiles 27 and fixed by tightening the screw connections of the stops so that the desired minimum position is defined downwards.
  • the stops 18 and 19 are fixed by axially displacing the shaft 22 by tightening the screw connections on the shaft 22 so that the minimum position is defined upwards and the maximum position downwards.
  • the stops 18 and 19 are designed so that the stop 19 in the direction of the maximum position, the stop 18 in the direction of the minimum position can be passed by the pin 33, since each stop is designed as an inclined plane in relation to the direction.
  • each position below the maximum position can be selected as the highest end position and that any higher position than the minimum position as the lowest position possible can be freely chosen between serving the table can be moved very quickly.
  • These freely selected end positions are secured at the top and bottom by stops. Loosening a stop is enough to move the table from one end position to the other.
  • special stoppers 45 can be provided, each connecting the two legs 10 of one leg and laying against the legs 11 in the maximum position.
  • the stop 17 for one leg 14 and possibly also for the other can be omitted if the foldability of the legs is carried out in such a way that they block in the desired minimum position, e.g. B. because the leg 10 bears against the stem 14. Another option would be ; to let the free end 15 move against the body 26 in this minimum position. One or even several separate stops can thus be dispensed with without the task of locking the frame on both sides in the minimum and maximum positions.
  • the stopper 45 can be replaced, e.g. B. by a stop on the drive housing or immediate blocking of the leg 10 on the trunk 14. Preferably, all stops act on one leg alone, the other is locked via the rope.
  • stops Since to move the table frame, the stops must be released, which block the movement into the maximum position and vice versa in the minimum position, these stops are both arranged on the shaft 22, pivotable by the lever 24 against a restoring force.
  • adjustable stops 17, 18, 19 and 25 mentioned can also be provided as non-detachable, for example welded, stops.
  • the joint unlocking of the stops in the minimum position blocking the way to the maximum position and vice versa is independent of whether one or more other stops are specially designed or are achieved by a blocking position of the frame.
  • the rope 29 is preferably guided below it in a plane parallel to the table top and moves in it.
