Definitions

  • the invention relates to an adjustment device for stepless height and Tilt adjustment of a level, especially for the stepless adjustment of the Seat of a hospital chair, with a lifting drive, a tilt drive and at least four struts.
  • Such adjustment devices have a variety of uses and are always needed where the task arises, one anyway level in terms of both height and orientation, i.e. in your Inclination to the horizontal to align. This is for example in the area of Machine tools the case where the problem often arises, too machining workpiece in a predetermined manner position or align according to the machining process.
  • Such adjustment devices are also used in Transport and lifting tools.
  • Such adjustment devices are also used in Transport and lifting tools.
  • An adjustment device of the generic type is in the German Utility model G 94 18 386.4 disclosed. With this adjustment device form four articulated struts parallelogram four-bar linkage. A limitation of Mobility of this four-bar linkage results from the fact that one of the four struts in the bearing (C) are not articulated, but rigid and immobile is stored.
  • This four-bar linkage is mounted in triplicate, with it being in one Bearing (C), which is linearly movable in a guide, is mounted and on the other hand via a fifth strut, which is connected to a strut of the Four-bar linkage attacks, is articulated to a fixed bearing (A), one on this fifth strut articulated linear drive, which itself in one another, third fixed bearing (H) is mounted, attacks.
  • C Bearing
  • A fixed bearing
  • H third fixed bearing
  • This adjustment device is due to the large number of components and due to their functional principle, relatively complex and complex. Both lead at higher manufacturing costs and greater susceptibility to failure of the Adjustment. Furthermore, one with the four-bar linkage connected level with a height adjustment due to actuation of the The inclination of the linear drive is always adjusted at the same time, i.e. when you adjust the height, you always want it or not the plane connected to the four-bar linkage in its orientation to Adjusted horizontal.
  • a Adjustment device for stepless height and incline adjustment Level especially for the continuous adjustment of the seat of a Hospital chair, the height adjustment and the Tilt adjustment are decoupled from each other in such a way that by a Height adjustment no tilt adjustment is caused.
  • the orientation of the first one changes Struts pair not and not even if the adjusting device by means of of the lifting drive acting on the second pair of struts in height is adjusted.
  • the orientation of the second changes Struts pair with deactivated linear actuator not and not even if the alignment of the first pair of struts by pressing the Tilt drive is changed, provided the lifting drive engages second strive.
  • a person in need of help whose hospital is with a Adjustment device according to the invention is equipped, for example Removing an object from the top compartments of a cupboard adjust his seat height by operating the linear actuator without the Inclination of the seat of the chair seat is changed or he a Inclination of the chair seat depending on the height adjustment would have to make or correct.
  • Embodiments of the adjustment device in which one of the two drives on a strut mounted in the fixed bearing (A) attacks, this drive itself being mounted in a stationary manner.
  • Such embodiments have increased stability because at least one strut of the four-bar linkage in two fixed bearings is fixed. This strut is thus sufficiently secured against twisting and can easily record moments. They are at least four The four-bar linkage also strives due to its articulated connection then sufficiently stable if none of the at least four struts double is stationary, but the strength of the adjustment device described embodiment has an increased rigidity.
  • the second strut of the second pair of struts becomes two stored strut and thus the adjusting device takes the shape of the advantageous embodiment described above.
  • An embodiment of the adjustment device can also be advantageous, which is characterized in that the linear actuator on the first strut attacks that of the second in the fixed bearing (A) articulated Strut opposite.
  • the linear actuator can also the linear actuator itself or him have the underlying operating principle. For example, come Pneumatic cylinders, but also electrically operated actuators or Tension elements for use.
  • Embodiments of the adjustment device in which the Tilt drive attacks on the second strut This will make the second Strut to a double fixed strut, which again Stability or rigidity of the device increased.
  • Adjustment device advantageous, in which the inclination drive on the first Strut attacks.
  • the adjusting device with regard to the question on which strut the Tilt drive is articulated this already applies to the linear actuator Highlighted.
  • Embodiments of the adjusting device are also advantageous, where the linear actuator itself is articulated and stationary.
  • the linear drive is not fixed and is supported on one of the two struts of the first pair of struts.
  • This one Struts are adjustable by operating the incline drive a non-stationary mounting of the linear actuator.
  • the linear actuator is preferred but stored stationary, which again the stability of the adjustment is increased.
  • the articulated mounting of the linear actuator enables one Height adjustment in wide areas. It can be articulated Storage of the linear actuator realize large adjustment paths, which in the Usually require a lifting drive that can move in the warehouse.
  • Adjustment device advantageous, in which the tilt drive itself articulated is stored, which is preferably mounted stationary.
  • the tilt drive can also be attached to one of the two struts support the second pair of struts. In this case, the tilt drive due to the mobility of the struts of the second pair of struts stored stationary.
  • Fixed storage and articulated storage preferred for the same reasons that of articulated and fixed storage underlying the linear actuator.
  • Embodiments of the adjustment device in which the Tilt drive is mounted on a strut of the second pair of struts This leads to a compactness of the adjustment device, even if this is under Circumstances leads to a loss in the stability of the device.
  • the adjustment device also tilts the first strut of the first pair of struts connected and to be adjusted Level when starting up backwards, which the operator of the hospital, who sits down on the seat, a feeling of security taught.
  • the order of magnitude that occurred when the level was started up Tilting movement can be due to the size of the difference in length of the two struts of the first pair of struts are influenced.
  • Embodiments of the adjusting device are also advantageous which the two struts of the first pair of struts are of equal length, where preferably the first strut of the second pair of struts is longer than the second Strut is.
  • the four struts 5 ', 5 ", 6', 6" of the two pairs of struts 5, 6 are each same length and parallel to each other.
  • the seat 7 is with the first strut 5 ' first pair of struts 5 firmly connected, the first strut 5 'part of the seat 7 and the seat 2, which represents the level 2 to be adjusted, in the Basic position is arranged horizontally.
  • the lifting drive 3 is on the first strut 6 'of the second pair of struts 6 articulated and stored in camp 8.
  • the tilt drive 4 is on the second Strut 5 "of the first pair of struts 5 articulated and stored in the bearing 9.
  • the second strut 5 "of the first pair of struts is thus mounted twice, whereby the adjusting device 1 has increased stability or rigidity having.
  • the lifting drive 3 attack for example on the second strut 6 "of the second pair of struts 6 to let or the inclination drive 4 on the first strut 5 'of the first Link pair of struts 5.
  • Fig. 2 shows the adjusting device shown in Fig. 1 in the raised position.
  • the lifting drive 3, which is mounted in the bearing 8, is extended and has the first strut 6 'of the second pair of struts 6 to which it is articulated and which is also mounted in the joint (B) of the second strut 5 "of the first pair of struts 5 to pivot this bearing (B).
  • the second strut 6 " which is connected to the first strut 6 'of the second pair of struts 6 via the two struts 5' and 5" of the first pair of struts, is always guided parallel to the first strut 6 'of the second pair of struts. This is due to the fact that the adjusting device 1 shown in FIGS.
  • struts 5 ', 5 ", 6', 6" of the two pairs of struts 5, 6 each have the same length are and thus form a special four-bar linkage, namely a parallelogram-shaped four-linkage.
  • the tilt drive 4 fixed in the bearing 9 holds the second strut 5 "of the second strut pair 5 unchanged in their height adjustment Position and thus due to the parallelogram four-bar linkage also the first strut 5 'of the first pair of struts 5, which at one parallelogram-shaped four-bar linkage always parallel to the second strut 5 "of the first pair of struts is positioned.
