Definitions

  • the invention relates to a bed with a height-adjustable mattress frame and a base frame, on the head side and foot side in each case pivotally connected by a pivot axis paired lever, on the load arms upward pairs of supports are articulated, one of which is firmly connected to the mattress frame and the other is pivotably articulated to the latter, and with the force arms of which a motor-driven spindle drive connected to the base frame is coupled in terms of drive, the force arms of which are always directed downward from their pivot axis in their pivoting regions.
  • the second angle lever can be pivoted independently of the first angle lever by means of a second motor-driven spindle drive, so that the mattress frame rises towards the head or foot on the side depending on the pivoting position of the angle lever is inclined, and can also be pivoted together with the second angle lever, as a result of which the mattress frame, approximately maintaining its respective horizontal or inclined position, is vertically adjustable.
  • the further spindle motor is arranged in a coupling rod between the angular gears. If this is actuated, it also lifts one side of the mattress. A lowering of this side under the other end of the mattress is achieved, on the other hand, in that manually operable locking stops form a limit for lowering one side when these locking stops have been brought into a locking position.
  • This locking device is easily accessible on the load arms of the angle lever, where they can interact with counter bearings on the frame and form a stable support.
  • the two pairs of angle levers are arranged on the base frame, each with an associated spindle drive, preferably in mirror image of the central transverse plane.
  • Their coupling is provided by an electrical control which, by pressing different buttons of a contact arrangement, either lifts on both sides, lifts on both sides, or lifts or lowers on one side on the head or foot side.
  • the load arms are the Angle lever arranged within the mobile base frame, which results in a support base on the mattress frame that is shorter by at least one load arm length, with a relatively large base frame length, whereby the mattress frame projects at least one end region relatively far beyond the pair of supports and therefore high support and bending moments on the load-bearing parts, Joints and motors are exercised, which requires a correspondingly massive execution of these parts.
  • An advantageous further development provides a high stability with a lighter design and a small base frame in that the two pivot axes of the angle levers are mounted so close to the ends of the base frame, the power arms still have sufficient freedom of pivoting and that at least one of the pairs of load arms angled so as to project over the base frame in its lower pivot position is designed.
  • the two pairs of angle levers are each arranged on the base frame, each with an associated spindle drive, preferably in mirror image of the central transverse plane.
  • the coupling of the drives for parallel lifting and lowering is provided by an electrical control system, which, by pressing different buttons on a contact arrangement, provides either lifting on both sides, lowering on both sides, or lifting or lowering on one side at the top or bottom of the mattress frame.
  • the two pairs of angle levers are arranged in the same direction at the ends of the base frame, only one pair of angle levers protruding beyond the base frame and the other lying inside. This arrangement provides a parallel movement of the angle lever and supports when lifting and lowering the Mattress frame.
  • Fig. 1 shows a side view of a bed with an i. a. mobile base frame (1) and a height-adjustable mattress frame (2).
  • On this corner pairs of downward supports (20, 21) are fastened, one of which is pivotable.
  • Load arms (30L, 31L) of pairs of angle levers (30, 31) are articulated on the supports (20, 21) and are mounted on transverse pivot axes (30S, 31S) on the base frame (1).
  • the power arms (30K '', 31K '') of the angle lever are offset by approximately 90 ° to the associated load arms (30L '', 31L ''), always pointing downwards.
  • the force arms (30K '', 31K '') are shown in the associated positions.
  • Fig. 2 shows a plan view of the first embodiment of the bed with the mattress frame removed.
  • the pivot axes (30S, 31S) of the angle levers are mounted in the base frame (1).
  • the load arm pairs (30L, 31L) on which the mattress frame supports (20, 21) are articulated are attached to these on the outside.
  • the first spindle drive (50, 51) is articulated on the inside on the base frame (1) on the one hand and on the one power arm (30K).
  • the connecting rod (4 ') of the power arms (30K, 31K) contains a second spindle drive (55, 56). Stops (71) are shown on the base frame (1), which cooperate with detent stops (72) on the load arms (31L), which can be adjusted with an actuating button (70).
  • This arrangement according to FIGS. 1 and 2 has the advantage that the coupling rod (4 ') can be easily replaced by one without a spindle drive if only one-sided inclination adjustment of the mattress frame (2) is required.
  • Fig. 3 shows schematically a further embodiment in which the angle levers (30, 31) and the associated drives (50, 51; 57, 58) are arranged mechanically independently of one another. These spindle drives are articulated on the base frame (1).
  • the motors (50, 57) of the spindle drives are each connected via a button (T3, T4) to a normally closed contact (R3, R4), so that when one of them is actuated, only one of the drives is to be controlled and thus the inclination the mattress frame (2) can be adjusted.
  • buttons (T1, T2) are provided, each containing a pair of changeover contacts (U1, U1 '; U2, U2') with which the drives can be actuated forwards or backwards, with the changeover switches (U1, U1 '; U2, U2 ') via break contacts prevents a short circuit when the pushbuttons (T1, T2) are actuated in error at the same time.
  • buttons can also be located on a correspondingly controlled relay.
  • the control device (ST) can also be configured in an equivalent manner in other contact arrangements, as shown, for example, in FIG. 4.
  • the use of work contacts (A2, A2 ') on the second button (T2) provides the same function, but less security against Malfunction when the contacts bounce while pressing the buttons (T1, T2) that serve the opposite function.
  • the angle levers (30, 31) and the motors (50, 57) are arranged symmetrically to the central transverse plane.
  • the angle levers (30, 31) are directed so that the spindle drives (50, 51; 57, 58) are always under tension.
  • the angle levers are arranged in reverse.
  • Figure 5 shows a top view of the first embodiment of the bed with the mattress frame removed.
  • pairs of downward supports (20, 21) are fastened in the corner areas, one of which is pivotally attached to the mattress frame.
  • Load arms (30L *, 31L) of pairs of angle levers (30, 31) are articulated on the supports (20, 21) and are mounted on transverse pivot axes (30S, 31S) on the base frame (1).
  • the power arms (30K *, 31K) of the angle levers are offset by approximately 90 ° to the associated load arms (30L *, 31L), always pointing downwards.
  • the pivot axes (30S, 31S) of the angle levers (30 *, 31) are mounted in the base frame (1).
  • the load arm pairs (30L *, 31L) on which the mattress frame supports (20, 21) are articulated are attached to these laterally.
  • the first spindle drive (50, 51) is articulated on the one hand on the base frame (1) and on one power arm (30K *), and on the other power arm (31K) is articulated on the second spindle drive (57, 56), which is connected to the base frame ( 1) is articulated on the other hand.
  • the innovation is that the load arms (30L *) of the a pair of load arms (30L *) extend over the end cross member (10) of the mobile base frame (1).
  • Fig. 6 shows schematically a longitudinal section of the first embodiment.
  • the angle levers and the associated drives (50, 51; 57, 56) are arranged mechanically independently of one another. These spindle drives are articulated on the base frame (1). To compensate for the differences in the distances between the load arm ends when the mattress frame (2) is inclined, the pair of supports (21) is articulated on the mattress frame (2).
  • the motors (50, 57) of the spindle drives are each connected via a button (T3, T4) to a normally closed contact (R3, R4), so that when one of them is actuated, only one of the drives is to be controlled and thus the inclination the mattress frame (2) can be adjusted.
  • buttons (T1, T2) are provided, each containing a pair of changeover contacts (U1, U1 *; U2, U2 *), with which the drives can be actuated forwards or backwards, with the changeover switches (U1, U1 *; U2, U2 *) via break contacts prevents a short circuit when the pushbuttons (T1, T2) are actuated by mistake.
  • these locking contacts can also be located on a correspondingly controlled relay or in an electronic logic circuit, which is technically equivalent.
  • the pair of load levers (30L *) protrudes in an angled shape from the end cross member (10) of the base frame (1).
  • the load arm legs (L1, L2) are placed horizontally or vertically.
  • the articulation of the supports (20) is lower in the lower position than the cross strut (10).
  • the control device (ST) can also be configured in other contact arrangements, as shown for example in FIG. 7.
  • the use of working contacts (A2, A2 *) on the second button (T2) in conjunction with the diode pairs (D) provides the function of lifting or lowering by simultaneously energizing both spindle motors (50, 57).
  • the limit switch arrangements and tilt limit switches of the mattress frame that are usually connected in series with the spindle motors (50, 57) are not shown.
  • the control device (ST) is equipped with an accumulator (B), which is to be fed from the mains via a charging power supply (NT).
  • a mains supply is advantageously possible for several hours of engine running time, which is particularly advantageous in the case of sick beds that are frequently moved to treat the patient and are on standby.
  • buttons (T31, T41) can be actuated individually or jointly to control one or the other lifting drive (50, 57), independently of the lifting and lowering buttons (T1, T2), which are locked against one another via a normally closed contact chain.
  • the angle lever (30 *, 31 *) and the motors (50, 57) are arranged symmetrically to the diagonal plane of the base frame (1).
  • the angle levers (30 *, 31 *) are directed so that the spindle drives (50, 51; 57, 56) are always under pressure. With such a spindle arrangement, the spindles are designed for this printing operation.
  • the load levers (30L *, 31L *) mounted there are angled so that they protrude at the end over the cross bars (10, 11) and, in the lower mattress frame position shown, are lower than the cross bars (10, 11) of the base frame (1) with the articulations of the supports (20 *, 21 *).
  • the pivotably articulated mattress frame support (21 *) in the lower mattress frame position, which is shown, is inclined towards the end of the frame (2), so that when the drive (57) of the other frame end is actuated, a lateral evasive movement of the frame is possible is, and the support (21 *) does not strike the cross bar (11).
  • circuit arrangement described can also be used advantageously with the beds according to the main application.
