Definitions
- the invention relates to a bed element which has a pivotable back part, a head part articulated thereto and optionally a foot part, and that these pivotable components can be moved by an electromotive adjusting device which has at least one drive motor and a threaded element which can be driven thereby and at least one placed thereon , Has adjustable adjustment element in the longitudinal direction of the threaded spindle.
- the couch element in question can be a slatted frame, a couch, a bed or the like.
- the back part and the head part can be pivoted by a so-called double drive.
- This double drive is equipped with one or two drive motors that drive the spindle at reduced speed via worm drives. It is controlled by a control unit and a hand switch.
- Each spindle nut acts on a link lever, which is firmly placed on the pivot axis of the back and / or the foot part.
- a standard bedding element is divided into the functional groups a) wooden frame and bedding construction, b) fitting components for the bedding construction including the swivel joints, fitting components for stiffening the entire construction and for generating the movement sequences and in the drive.
- the invention is based on the object, possibly also by modifying the aforementioned functional groups, to design a lying element of the type described at the outset in such a way that it is possible to dispense with the articulation levers which are perceived as disruptive, and in that the forces required for adjustment are provided by a suitable Kinematic system can be transmitted from the drive motor or from the drive motors to the foot and / or the back part.
- an articulated lever acting in the manner of a toggle lever is connected to raise the backrest.
- the principle of a toggle is well known.
- the two levers are one-armed levers and are connected to each other via the knee or the joint.
- One free end of the lever is connected to a fixed bearing, while the free end of the second Lever performs a linear movement when a force acts on the knee or joint.
- the articulated lever also consists of the two one-armed levers and the knee.
- the peculiarity is that a free end of one lever is connected to the backrest so that it moves when the free end of the other lever is moved by the adjusting element moving on the spindle.
- the force that is applied to the joint is therefore derived in the special design from the movement of the adjusting element.
- one lever of the articulated lever is articulated on the adjusting element and the other lever on the back part and that when the
- the joint performs a guided linear movement and a rotary movement leading to blocking the articulated lever in a certain angular position.
- the joint follows the movement of the adjusting element synchronously.
- the joint is actuated by the lever articulated on the adjusting element
- the arrangement is designed such that from the time the adjustment element is moved out of the end position until the articulated lever is blocked, the backrest is pivoted into such a position that, despite the relatively low forces, it is pivoted out of the unfavorably stretched position into an angular position becomes. Blocking the articulated lever in a predetermined angular position of the two one-armed levers results in a more favorable position in terms of force in order to raise the back part. After blocking the articulated lever, it acts like a rigid angle lever.
- a fixed guide pin to be attached to it, which is supported on a stationary guide track during the movement of the joint in such a way that the backrest can be pivoted into the more favorable position.
- the moment necessary for the rotation of the joint can be easily achieved if the guide pin is offset in relation to the joint point in the direction of the backrest.
- the resulting lever arm is relatively small due to the structural conditions, but is sufficient to first raise the backrest by a small acute angle.
- the lever connected to the backrest is mounted on a crossbar connecting the side parts. The movement of this crossbar which results when the backrest is raised can be used to drive a linkage for pivoting the headrest. This linkage is advantageously a crank mechanism.
- the articulated lever in connection with the
- each crank mechanism is designed in such a way that the headrest is swiveled ahead of the backrest. When the headrest is in the end position, more favorable to optimal conditions have resulted for the articulated lever which adjusts the backrest. This reduces the force required to adjust the backrest.
- each crank mechanism consists of a crank mounted on the associated side part of the backrest and a crank rod articulated on the headrest and connected to the crank.
- the crank could also be referred to as a double crank, since it is advantageously designed as a two-armed lever, the crank rod articulated on the headrest on one lever arm and the crossbar connecting the two other lever arms to which the articulated lever is articulated ,
- the rotational movement of both cranks is derived in the simplest way from one element.
- the lever arms of the crank are of equal length.
- the crank rods are advantageously articulated on cantilevers which are firmly attached to the side parts of the headrest. As a result, the articulation points of the two crank rods can be offset in height from one another, so that a sufficient force is available at the start of the pivoting movement of the headrest.
- the lying element is also equipped with a foot part which is advantageously formed from two foot part elements which are connected to one another in an articulated manner and which are in the extended position in angular positions relative to one another.
- guide links are mounted on the foot part element facing away from the backrest, the other ends of which are articulated on the longitudinal spars of the lying element.
- a threaded spindle is also assigned to the foot part, on which an adjusting element is placed, which can be moved in the longitudinal direction.
- an upright lever To the- This adjusting element is articulated an upright lever which pivots the foot part elements from the end position when the adjusting element is moved.
- FIG. 1 shows a lying element according to the invention with a flat backrest and a flat headrest
- FIG. 2 the lying element according to FIG. 1 with the headrest extended
- Figure 3 is a partial view of the lying element with the backrest raised
- FIGS. 1 to 3 shows the lying element according to FIGS. 1 to 3 with the backrest extended even further.
- the lying element 10 shown in the figures is designed as a slatted frame which is equipped with a backrest 11 and a headrest 12 articulated to it.
- the lying element 10 is one of two
- the two levers are connected to one another in an articulated manner by a bolt 21 in a manner not explained in detail.
- the lying element 10 is also provided with a stationary th slide guide 22 equipped, which is arranged parallel to the threaded spindles 16, 17.
- a guide pin 23 is also provided, the mode of operation of which will be explained in more detail.
- the pivot axis of the backrest 11 is identified by the reference symbol 24.
- the lever 20b is connected to a crossbar 25, which with their
- cranks 26 are mounted on the side parts of the backrest 11, which are connected to the backrest 11 via crank rods 27.
- the ends of the crank rods 27 facing away from the transverse rod 25 are articulated on arms 28.
- a raising lever 29 is mounted on the adjusting element 19 for the foot part 15, the other end of which is articulated on the hinge axis of the two foot part elements 13, 14.
- two guide links 30 are articulated laterally, the other ends of which are articulated on the side parts of the lying element 10.
- the foot part elements 13, 14 are at an angle to one another.
- the foot part is shown in a partially extended position in the figures.
- a stop 31 is provided on the lever 20a articulated on the adjusting element 18, against which the the adjustment element 18 facing surface of the lever 20 strikes.
- the extended position of the headrest 12 is shown in FIG. 2. Due to the slightly raised backrest 11, it is at a small acute angle to the horizontal. This would then create optimal leverage for the further uprighting of the backrest 11. If the adjusting element 18 is now moved further in the direction of the pivot axis 24 of the backrest 11, this is pivoted into the end position shown in FIG. 4, the position of the headrest 12 remaining unchanged. The backrest 11 is retracted in the reverse manner.
- a motor is provided for operating the threaded spindles 16, 17.
- the gearbox reducing the engine speed then contains coupling elements which make it possible to connect only one of the two threaded spindles 16, 17 or both together to the engine in terms of gearbox technology.
- the guide pin 22 and the joint 21 could lie concentrically one above the other.
- the invention is not restricted to the exemplary embodiment shown. It is essential that the articulated lever 20 connected to the adjusting element 18 is blocked from a certain position of the adjusting element 18 or the backrest 11 and acts like a rigid lever. It is also important that the backrest 11 is pivoted during or after the leading pivoting movement of the headrest 12, so that the required force is reduced when the backrest 11 is subsequently fully extended. Overall, the arrangement of the components used to adjust the backrest 11 and the headrest 12 should be such that the arrangement does not protrude from the upper and lower surfaces of the lying element 10 when the backrest 11 and the headrest 12 are laid flat.
