Definitions
- the invention relates to a mattress frame with the features of the preamble of claim 1.
- Such a mattress frame is from the publication DE 10 2009 034 016 B4 known.
- the mattress frame rests on a support frame and can be brought out of the care bed for a caregiver by turning it 90 ° perpendicular to the lying surface into a standing position.
- the mattress which is preferably in one piece on the mattress frame, can be provided with a separate part at the foot end and the thigh part and the lower leg part of the leg part must be lifted out of the lying surface.
- the thigh part and the lower leg part are connected to one another via preferably two articulated locking joints.
- the mechanics of the articulated locking joints are designed so that e.g. motorized lifting of the thigh part relative to the fixed support frame, the lower leg part is automatically aligned in a position parallel to the lying surface.
- the mechanics of the articulated locking joints are designed so that when the thigh part is lowered after rotation to the standing position, the lower leg part is automatically aligned in a position perpendicular to the side surface of the nursing bed.
- the invention was therefore based on the object of reducing the mechanical complexity of the articulation of the lower leg part to the upper leg part and, moreover, of producing an increased stability of the positions of the lower leg part.
- FIG. 1a The schematic longitudinal section shown shows a mattress frame 1 parallel to a support frame 2
- Mattress frame 1 consists of a central part 3, which is rotatably mounted on the support frame 2 in a plane perpendicular to the plane of the drawing.
- a back part 4 is pivotally articulated and, on the other hand, a leg part consisting of a thigh part 5 and a lower leg part 6.
- the thigh part 5 and the lower leg part 6 are connected to one another via an articulated locking joint 7.
- the thigh part 5 can be raised via a device 8 relative to the fixed support frame 2.
- FIG. 1b A raised position of the thigh part 5 is in Fig. 1b schematically shown, wherein the mechanics of the articulated locking joint 7 brings the lower leg part 6 into an orientation essentially parallel to the support frame 2.
- the resilience of the lower leg part 6, for example by a pressure symbolically represented as arrow 9, is low.
- FIG. 1c The arrangement shown is intended to clarify the position of the lower leg part 6 reached in front of the side surface 10 as the bed edge of a nursing bed after the middle part 3 has been rotated, after the lower leg part 6 has been lowered.
- a mattress not shown, generates a tensile stress on the lower leg part 6 due to its angling on the articulated locking joint 7 and its attachment to the lower leg part 6, which is represented by a further symbolic arrow 11.
- the housing of the electric motor 13 is articulated to a tab 15 which is fastened vertically downward to a cross strut of the thigh part 5 directed towards the foot end.
- An axis of rotation fastened to the tab 15 is therefore at a distance from the underside of the thigh part 5, while the axis of rotation is arranged at the head of the drive rod 14 as close as possible to a cross strut arranged at the foot end of the lower leg part 6.
- both the housing of the electric motor 13 and the head end of the drive rod 14 are to be rotatably supported, the axes of rotation being parallel to the transverse direction of the thigh part 5 and the lower leg part 6.
- FIG. 3 The illustrated embodiment shows in a bottom view a raised lower leg part 6 on an inclined thigh part 5. Both parts are connected to one another via a simple swivel joint 12.
- the housing of the electric motor 13 is rotatably articulated on a tab 15 which is fastened vertically to a cross strut at the end of the thigh part 5.
- the drive rod 14 is on the lower leg part 6 attached.
- the arrangement of the motor 13 and the drive rod 14 are arranged almost centrally to the transverse direction of the mattress frame 1, so that a single drive device is sufficient.
- the coupling between motor 13 and drive rod 14 is so strong that the pressure and tensile loads described above are effectively overcome.
- FIG. 4 The exemplary embodiment shown shows the lower leg part 6 with the thigh part 5 attached to it via a swivel joint 12.
- the thigh part 5 is lowered in front of the side surface 10 after the middle part 3, not shown, has been rotated.

Abstract
Ein Matratzenrahmen (1) mit in einer Ebene drehbar angeordnetem Mittelteil (3), daran schwenkbar angelenktem Rückenteil (4) und Beinteil mit knickbarem Oberschenkelteil (5) und Unterschenkelteil (6), zeichnet sich dadurch aus, dass zum Knicken des Unterschenkelteiles (6) gegenüber dem Oberschenkelteil (5) ein unterhalb des Matratzenrahmens (1) angeordneter elektromotorischer Antrieb (13, 14) vorgesehen ist.A mattress frame (1) with a central part (3) rotatably arranged in one plane, a pivoting articulated back part (4) and a leg part with a foldable thigh part (5) and lower leg part (6), is characterized by the fact that for bending the lower leg part (6) an electric motor drive (13, 14) arranged below the mattress frame (1) is provided opposite the thigh part (5).
Description
Die Erfindung betrifft einen Matratzenrahmen mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a mattress frame with the features of the preamble of
Ein solcher Matratzenrahmen ist aus der Druckschrift
Die Mechanik der Knick-Rast-Gelenke ist dabei so ausgelegt, dass bei einem z.B. motorisch ausgeübten Anheben des Oberschenkelteiles gegenüber dem feststehenden Auflagerahmen das Unterschenkelteil automatisch in eine Position parallel zur Liegefläche ausgerichtet wird.The mechanics of the articulated locking joints are designed so that e.g. motorized lifting of the thigh part relative to the fixed support frame, the lower leg part is automatically aligned in a position parallel to the lying surface.
Außerdem ist die Mechanik der Knick-Rast-Gelenke so ausgelegt, dass bei einem Absenken des Oberschenkelteiles nach Drehung in die Aufstehposition das Unterschenkelteil automatisch in eine Position senkrecht zur Seitenfläche des Pflegebettes ausgerichtet wird.In addition, the mechanics of the articulated locking joints are designed so that when the thigh part is lowered after rotation to the standing position, the lower leg part is automatically aligned in a position perpendicular to the side surface of the nursing bed.
Die Konstruktion und Fertigung der Knick-Rast-Gelenke sind sehr aufwändig. Außerdem ist die Belastbarkeit des angehobenen Unterschenkelteiles an dem Knick-Rast-Gelenk eingeschränkt. Die senkrechte Ausrichtung des Unterschenkelteiles in der Aufstehposition ist labil gegenüber einer gebogen aufgelegten Matratze. Dadurch wird die Matratze gegenüber dem Bettrahmen immer etwas vorstehen, so dass eine Pflegeperson beim Einsetzen in das Pflegebett gegenüber der Sitzfläche beabstandet ist.The design and manufacture of the articulated locking joints are very complex. In addition, the load capacity of the raised lower leg part on the articulated locking joint is restricted. The vertical alignment of the lower leg part in the standing position is unstable compared to a curved mattress. As a result, the mattress will always protrude slightly from the bed frame, so that a caregiver is spaced from the seat when inserted into the care bed.
Der Erfindung lag daher die Aufgabe zugrunde, den mechanischen Aufwand der Anlenkung des Unterschenkelteiles an den Oberschenkelteil zu vermindern und außerdem eine erhöhte Stabilität der Positionen des Unterschenkelteiles herzustellen.The invention was therefore based on the object of reducing the mechanical complexity of the articulation of the lower leg part to the upper leg part and, moreover, of producing an increased stability of the positions of the lower leg part.
Diese Aufgabe wird bei einer Matratzenauflage der eingangs genannten Art durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausbildungen der Erfindung ergeben sich aus den Merkmalen der Unteransprüche.This object is achieved in a mattress topper of the type mentioned by the characterizing features of

Zum Einsetzen in das Pflegebett wird eine Pflegeperson rückwärtsgehend an das Pflegebett herangeführt bis ihr Unterschenkel die Matratze berührt. Da die Pflegeperson in dieser Stellung von der Bettkante 10 entfernt steht, wird das Einsetzen erschwert und erfordert einen erhöhten Stützaufwand.To insert them into the nursing bed, a caregiver is guided backwards to the nursing bed until their lower legs touch the mattress. Since the caregiver is in this position from the
