  • At least one part of the rods in one of the rod mechanisms includes the outside of the square, the corners of which the four pivot points of the rod mechanism in question are formed, and that the driver preferably affect this part.
  • the Rod mechanism set up so that the Rectangle, the corners of which are from the four pivot points of the relevant rod mechanism are formed, a Is parallelogram.
  • At least one of the rod mechanisms additionally one separately mounted pivoted arm include its free Influenced the associated couch section.
  • a transmission mechanism coupled to a back piece available, the one with the back piece preferably rigid arm connected.
  • the couch sections a stationary Seat piece, one at one end of the seat piece articulated movable back piece, one to the other End of the thigh articulated at its end as well one articulated to the other end of the thigh piece connected movable shin piece.
  • the drivers are designed as roles, preferably on shafts attached to the drive rod are stored.
  • the lying area is a number among themselves articulated sections, namely a back piece 2, a seat piece 3, a thigh piece 4 and a shin piece 5.
  • the seat 3 is compared to a frame, not shown, for example a bed frame, fixed.
  • the Back piece 2 is on by means of a first joint 32 one end of the seat piece 3 with this pivotable connected.
  • the thigh piece 4 is pivotally connected to the seat.
  • On the other end of the thigh piece 4 is by means of of a joint 54, in turn, a shin piece 5 articulated.
  • a linear Movable actuator 1a provided to operate the bed.
  • the actuating device is in an intermediate position, so that the actuator 1a move in both directions along its length can, as indicated by a double arrow 41.
  • the actuator 1a is at one end a drive rod 17 having a first length 17a and has a second length 17b.
  • Around The drivers are to reduce friction losses preferably equipped with wheels or castors.
  • the drive rod 17 is set up in such a way that by means of a triggerable connection 16a, 16b the first length 17a and the second length 17b can be separated from each other, whereby only the second length 17b, which the actuator 1 on next lies with the actuating element 1a stays connected.
  • This separation can be electromagnetic, for example take place, optionally by means of an electromagnetic triggerable jack. This has the advantage that the separation is remotely controlled from the same unit, which is also used to operate the bed, can be done.
  • the separation can also be carried out according to the invention a jack, which is connected to a in the frame (bed frame) stored eccentric element triggered so that the separation is only in the neutral lying position takes place where there is neither tension nor pressure on the drive rod is exercised.
  • Manual operation This type can be designed in such a way that is largely secured against incorrect operation.
  • the drivers 171 and 172 are on each side a first exchange mechanism arranged, the comprises four rods 24, 25, 26 and 27, which in four Points 8, 9, 10 and 11 hinged together are so that a square is created.
  • the poles 24 and 25 are not on the rods 26 and 27 connected to their endpoints, but at one point a little further down, so that except for the corners of the Quadrilaterals formed from points 11 and 10 relevant extensions 24a and 25a of the Quadrilaterals arise. These extensions serve as Stop for the relevant drivers 171 and 172.
  • the rods 24 and 25 are articulated at their end points; in this case rods 24 and 25 (or 26 and 27) per se, i.e. the sides of the square as a stop for the relevant carriers 171 and 172 to serve.
  • the point 9 where the rods 24 and 25 are together are connected is fixed to a frame.
  • Point 8 where the rods 26 and 27 are together are articulated with a swivel arm 6 connected, which is stationary in relation to the frame Point 7 is stored.
  • the shin piece lies at the end of the arm 6 5 with the aid of a rolling element 28 on the arm 6.
  • the drivers 173 and 174 are on each side a second transmission mechanism arranged, the comprises four rods 19, 20, 21 and 22, which in four Points 12, 13, 14 and 15 among themselves are articulated so that a square is created. This corresponds to the first transmission mechanism. So are rods 19 and 20 with rods 21 and 22 are not connected at their endpoints, but at a point below, which means that the points 12 and 13 formed corners of the square relevant extensions 19a and 19b of the pages of the square arise. These extensions serve as a stop for the associated driver 173 and 174. Poles 19 and 20 could also be attached to the Endpoints would be connected, and in this case, would rods 19 and 20 (or 21 and 22), that is Sides of the square as a stop for the associated Carriers 173 and 174 serve.
  • the second transmission mechanism makes a difference differs from the first in that point 14, where the rods 21 and 22 are connected together are not attached to a swiveling arm, but directly to the thigh piece 4 on one Point that is opposite the ends of the thigh piece and is stationary between them.
  • the driver 175 is arranged such that it unilaterally affect a third replacement mechanism can, as shown in Fig. 1, in its simplest form one with the back piece 2 stiff connected arm 29 includes, whereby the back piece 2 can pivot about the joint 32.
  • a transmission mechanism according to the first or the second transmission mechanism use which is then one-sided from the driver 175 being affected.
  • Fig. 1 there is also an operating unit outlined, with the help of which the actuator is controlled can be.
  • This control unit is not part of the invention and is therefore not described in detail, and is in the rest for the same reason Figures omitted.
  • FIG. 2 shows a situation that arises when the actuator 1 the actuator 1a moved to the right in Fig. 2, as with indicated by an arrow 42.
  • the movement of the actuator 1a is on the drive rod 17th and thus transferred to the driver 171-175, so that they also move to the right.
  • the driver 171 influences the first one Transmission mechanism on the rod 25 and / or their extension 25a, so that the hinge point 10 shifted to the right and hinge point 8 upwards becomes.
  • the arm 6 stored in point 7 becomes influenced in such a way that he is one around the point 7 executes a swiveling movement.
  • the rolling element 28 pivots and moves the shin piece resting on it 5 towards the top.
  • the use of the Roller organ 28 for transmitting the movement from the arm 6 on the shin part 5 is advantageous because this is a relative movement between the end point of the Armes 6, where the roller 28 is located, and the Shin 5 allows. This can, as from the further description shows the movement of the Shin piece 5 also a translational composite include.
  • the driver 173 influences the second transmission mechanism with the rod 20 and / or their Extension 20a, so that the hinge point 12 after right and pivot point 14 shifted upwards becomes.
  • the thigh piece 4 the one end is supported at point 34, influenced in such a way that the thigh piece 4 around the point 34 makes a swinging movement.
  • the other end of the Thigh piece that at point 56 to the shin piece 55 is articulated, that influences Shin piece in the upward direction. From the two Influencing the shin piece 5 from the arm 6 or the thigh piece 4 results in a Movement of the shin piece 5, not only pivoting, but also translational.
  • the driver 175 influences that with the Back piece 2 rigidly connected arm 29 so that this a pivoting movement about the hinge point 32 executes. This pivots due to the rigid connection Back piece 2 accordingly.
  • FIG. 3 shows a situation that arises, when the actuator 1 the actuator la moved to the left, as indicated by an arrow 43. According to the situation in Fig. 2, the movement of the actuator 1a on the drive rod 17 and thus transferred to the drivers 171-175, however such that this is a movement here run to the left.
  • the driver 172 influences the first transmission mechanism on rod 24 and / or their extension, so that the hinge point 11 moved to the left and hinge point 8 upwards becomes. This movement is on the arm 6 on the Transfer shin piece 5 in the same way as in the situation shown in FIG. 2.
  • Influencing the second transmission mechanism corresponds to the situation in Fig. 2, only with the Difference that influencing from the other Side and the other way, so it here is bring-along 174, who is rod 19 and / or its extension 19a affects, while the driver 173 moves away from the transmission mechanism will without influencing this.
  • the driver 175 is the one with the back piece rigidly connected arm 29 moves away so that this and thus the back piece 2 does not affect will.
  • This movement of the back piece 2 corresponds to the situation shown in Fig. 2, where the driver 175th the arm 29 rigidly connected to the back piece 2 influenced so that the arm 29 and the back piece 2 together a pivoting about the pivot point 32 Carry out movement.
