Description

Verstellbare Liege oder BettAdjustable couch or bed
Die Erfindung betrifft eine verstellbare Liege oder Bett. Im weiteren wird nur von Liege gesprochen. Das schließt nach der Erfindung das Bett ein .The invention relates to an adjustable bed or bed. In the following, we will only speak of a couch. This includes the bed according to the invention.
Solche Liegen sind hinlänglich bekannt. Zur Verstellung der Liegen sind die Liegen vorzugsweise in mehrere Abschnitte unterteilt, die schwenkbeweglich miteinander verbunden sind. Ferner gehört zur Verstellung zumindest eine Arretierung für die beweglichen Teile in der jeweiligen Schwenkstellung.Such couches are well known. To adjust the couches, the couches are preferably divided into several sections which are pivotally connected to one another. The adjustment also includes at least one locking device for the moving parts in the respective swivel position.
Darüber hinaus sind Liegen bekannt, die an verschiedenen Teilen zugleich mit einer motorischen Verstellung versehen sind. Die motorische Verstellung erlaubt eine Verstellung während des Liegens bis in jede gewünschte Position. Ohne motorische Verstellung sind die meisten Personen gezwungen, sich der optimalen Position in mehreren Versuchen zu nähern.In addition, couches are known, which are provided on different parts with a motorized adjustment. The motorized adjustment allows adjustment to any desired position while lying down. Without motor adjustment, most people are forced to approach the optimal position in several attempts.
Dabei muß mehrmals aufgestanden werden, eine Verstellung erfolgen und wieder dieIt must be stood up several times, an adjustment must be made and again
Liegendstellung eingenommen werden.Lie in a prone position.
Bei motorischer Verstellung erübrigt sich das. Der Komfort einer motorischen Verstellung wird als beträchtlich angesehen.This is not necessary with motorized adjustment. The comfort of a motorized adjustment is considered to be considerable.
Die motorische Verstellung beinhaltet zugleich eine Verletzungsgefahr. Das gilt besonders, wenn die Liege aus einem Sitzteil und daran verstellbar befestigten Oberkörperteilen und Beinteilen besteht. Wenn beide Teile von einer aufliegenden Person gegeneinander verstellt werden, kann die aufliegende Person zwischen beiden Teilen geklemmt werden. An anderen Liegen besteht eine Verletzungsgefahr für die Füße, weil die Füße unter dem Fußteil geklemmt werden können.The motorized adjustment also contains a risk of injury. This is especially true if the bed consists of a seat part and upper body parts and leg parts that are adjustably attached to it. If both parts are adjusted against each other by an overlying person, the overlying person can be clamped between the two parts. There is a risk of injury to the feet on other loungers because the feet can be clamped under the foot section.
Die Erfindung hat sich die Aufgabe gestellt, die Verletzungsgefahr zu beseitigen. Nach der Erfindung wird das dadurch erreicht, daß zumindest zu jedem schwenkbeweglich Teil, von dem eine Verletzungsgefahr ausgeht, ein separater Versteilmotor vorgesehen ist und daß zu jedem Versteilmotor eine Wegbegrenzung gegenüber dem benachbarten Liegenteil vorgesehen ist. Damit wird sichergestellt, daß sich benachbarte Liegenteile einander nicht übermäßig annähern und dadurch eine Verletzungsgefahr verursachen. Die Vorteile sind besonders für Liegen mit einem Oberkörperteil und einem separaten Beinteil wichtig. Zusätzlich ist vorzugsweise eine Wegbegrenzung für das Beinteil und das Fußteil vorgesehen, so daß ein Klemmen der Füße zwischen dem Fußteil und dem Untergrund verhindert wird.The object of the invention is to eliminate the risk of injury. According to the invention, this is achieved in that a separate adjusting motor is provided for at least each pivotable part from which there is a risk of injury, and in that for each adjusting motor there is a path limitation with respect to the adjacent lying part. This ensures that adjacent parts of the bed do not come excessively close to one another and thus cause a risk of injury. The advantages are particularly important for couches with an upper body part and a separate leg part. In addition, a path limitation for the leg part and the foot part is preferably provided, so that a jamming of the feet between the foot part and the ground is prevented.
Vorzugweise sind Verstellmotore mit Selbsthemmung und/oder mit Arretierung vorgesehen. Die Selbsthemmung entsteht z.B. durch Verwendung eines Getriebes mit einer Spindel oder einer Gewindestange. Dabei kann auf der Spindel oder Gewindestange z.B. eine Mutter sitzen. Es können die Spindel bzw. die Gewindestange und/oder die Mutter drehbeweblich angeordnet sein. Mit der Spindel kann auch ein Zahnrad zusammenwirken. Im Falle der Verwendung eines Zahnrades ist zumindest die Spindel bzw. die Gewindestange mit einem Antriebsmotor versehen. Die Selbsthemmung der Spindel bzw. Gewindestange ist um so stärker, je geringer die Steigung der Spindel bzw. die Steigung des Gewindes auf der Gewindestange ist.Adjustment motors with self-locking and / or locking are preferably provided. Self-locking occurs e.g. by using a gearbox with a spindle or a threaded rod. Here, e.g. on the spindle or threaded rod a mother sit. The spindle or the threaded rod and / or the nut can be arranged such that they can rotate. A gearwheel can also interact with the spindle. If a gearwheel is used, at least the spindle or the threaded rod is provided with a drive motor. The self-locking of the spindle or threaded rod is stronger, the lower the pitch of the spindle or the pitch of the thread on the threaded rod.
Anstelle der Selbsthemmung oder zusätzlich kann auch eine mechanische und/oder elektronische bzw. elektrische Arretierung vorgesehen sein. Vorzugsweise ist eine motorische Arretierung vorgesehen.Instead of self-locking or additionally, mechanical and / or electronic or electrical locking can also be provided. A motorized lock is preferably provided.
Wahlweise sind die Spindel bzw. die Gewindestange und/oder die Mutter mit einem Antriebsmotor versehen. Die Antriebsmotore können zugleich eine Arretierung besitzen. Günstig sind Schrittmotore. Schrittmotore sind im Handel mit Arretierung in der jeweiligen Schrittstellung verfügbar.The spindle or the threaded rod and / or the nut are optionally provided with a drive motor. The drive motors can also have a lock. Stepper motors are cheap. Stepper motors are available in the locking position in the respective step position.
