Abstract

The aim of the invention is to prevent users of sofas or beds comprising pivotable parts and a motor-actuated adjusting drive unit from getting injured due to an improper adjustment. Said aim is achieved by the fact that the adjusting device is disposed in a compact manner underneath the sofa or bed while the distance remains unchanged when the sofa or bed is adjusted such that the contour of the adjusting device is essentially the same as that of the support area of the sofa or bed following an adjustment.

Description

Die Erfindung betrifft eine verstellbare Liege oder Bett. Im weiteren wird nur von Liege gesprochen. Das schließt nach der Erfindung das Bett ein.
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.
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. Dabei muß mehrmals aufgestanden werden, eine Verstellung erfolgen und wieder die Liegendstellung eingenommen werden.
Bei motorischer Verstellung erübrigt sich das. Der Komfort einer motorischen Verstellung wird als beträchtlich angesehen.
Die bekannten Liegen besitzen schwenkbewegliche Teile für die Oberkörperverstellung und für die Beinverstellung. Zum teil sind auch Liegen bekannt mit schwenkbeweglichen Teilen für die Kopfverstellung und für die Fußverstellung.
Bekannt ist auch die Verwendung von separaten Verstelleinrichtungen für jedes schwenkbewegliche Teil bzw. von Versstellmotoren als Verstelleinrichtungen. Die unabhängigen Verstelleinrichtungen erlauben dem Benutzer eine individuelle Einstellung der Liege.The invention relates to an adjustable bed or bed. In the following we only talk about Liege. This includes the bed according to the invention.
Such couches are well known. To adjust the beds, the beds are preferably divided into several sections which are pivotally connected to each other. Furthermore, at least one lock for the moving parts in the respective pivot position belongs to the adjustment.
In addition, couches are known, which are provided at different parts at the same time with a motorized adjustment. The motorized adjustment allows adjustment while lying down to any desired position. Without motor adjustment, most people are forced to approach the optimal position in multiple trials. It must be gotten up several times, carried out an adjustment and again the prone position be taken.
With motorized adjustment, this is unnecessary. The comfort of a motorized adjustment is regarded as considerable.
The known couches have pivoting parts for the upper body adjustment and leg adjustment. For some are also known couches with pivoting parts for the head adjustment and for the foot adjustment.
Also known is the use of separate adjustment for each pivoting part or of adjusting motors as adjusting. The independent adjustment allow the user an individual adjustment of the bed.

Eine Liege mit motorischer Verstellung ist aus der DE 19903112 A1 bekannt. Dort ist eine Oberkörperverstellung und eine Beinverstellung mit jeweils einem Verstellmotor vorgesehen. Die beiden Motore wirken allerdings über eine umfangreiche Hebelmechanik aus die schwenkbeweglichen Teile der Liege. Die zugehörigen Hebel sind seitlich in der Liege bzw. unter der Liege angeordnet.A couch with motorized adjustment is known from DE 19903112 A1. There, an upper body adjustment and a leg adjustment, each with an adjusting motor is provided. However, the two motors act on a comprehensive lever mechanism of the pivoting parts of the deck. The associated levers are arranged laterally in the couch or under the bed.

Auch die DE 4305939 A1 zeigt eine Liege mit einer motorischen Verstellung. Unabhängige Verstellmotore sollen die schwenkbeweglichen Teile der Liege bewegen. Wie bei vorstehend beschriebenen Liege wirken die Motore allerdings wiederum über eine Hebelmechanik auf die schwenkbeweglichen Teile, wobei die Hebel seitlich in der Liege angeordnet sind.The DE 4305939 A1 also shows a couch with a motorized adjustment. Independent Verstellmotore to move the pivoting parts of the lounger. However, as with the deck described above, the motors in turn act via a lever mechanism on the pivoting parts, the levers being arranged laterally in the deck.

Eine Liege mit motorischer Verstellung ist auch aus der US-A-6343392 bekannt. Dort ist wie bei der DE19903112 A1 eine Oberkörperverstellung und eine Beinverstellung mit jeweils einem Verstellmotor vorgesehen. Darüber hinaus ist auch eine Kopfverstellung und eine Fußverstellung vorgesehen, jedoch werden die Kopfverstellung und die Beinverstellung über eine Hebelmechanik von der Schwenkstellung der schwenkbeweglichen Teile für die Oberkörperverstellung und die Beinverstellung abgeleitet.A recliner with motorized adjustment is also known from US-A-6343392. There, as in DE19903112 A1, an upper body adjustment and a leg adjustment, each with an adjusting motor, are provided. In addition, a head adjustment and a foot adjustment is provided, however, the head adjustment and the leg adjustment are derived via a lever mechanism of the pivotal position of the pivoting parts for the upper body adjustment and the leg adjustment.

Eine Liege mit motorischer Verstellung ist ferner aus der US-A-4258445 bekannt. Dort sind verschiedene Möglichkeiten aufgezeigt, wie mit einer Mechanik unterschiedliche Liegestellungen und Sitzstellungen erreichbar sind. Darüber hinaus sind einige Ausführungsbeispiele mit schwenkbeweglichen Teilen wie bei der US-A-6343392 gezeigt. Diese Liege zeigt eine extreme Hebelmechanik.A recliner with motorized adjustment is also known from US-A-4258445. There, various possibilities are shown, as with a mechanism different reclining positions and seating positions can be achieved. In addition, some embodiments are shown with pivoting parts as in US-A-6343392. This lounger shows an extreme lever mechanism.

Eine Liege mit motorischer Versstellung ist aus der US-A-4407030 bekannt. Die bekannte Liege besitzt mehrere schwenkbewegliche Teile, die durch Verstellmotore bewegt werden. Diese Druckschrift weißt ausdrücklich auf die Verletzungsgefahr für den Benutzer hin. Zwischen den Motoren und den schwenkbeweglichen Teilen der Liege ist eine umfangreiche Hebelmechanik vorgesehen. Die zugehörigen Hebel sind im Seitenbereich der Liege angeordnet. Dies dient erkennbar der Stabilität, hat aber eine erhebliche Verletzungsgefahr zur Folge. Die verletzungsgefahr soll durch Sensoren verhindert werden, welche reagieren, wenn ein Benutzer mit seinen Händen oder Füßen aus Versehen in die Mechanik greift. Die Sensoren beinhalten allerdings das Problem, dass sie in ihrem Reaktionskreis auch auf andere Teile als Hände und Füße des Liegenbenutzers reagieren. Jedes herunterhängende Laken oder Decke kann die Sensoren zum reagieren bringen. Desgleichen jede hinzutretende Person und alle Gegenstände, welche sich zu dicht an der Liege befinden. Deshalb ist verständlich, dass die Sensorenlösung sich in der Praxis nicht durchsetzen konnte.A couch with motorized adjustment is known from US-A-4407030. The well-known lounger has several pivoting parts that are moved by adjusting motors. This document explicitly states the risk of injury to the user. Between the engines and the pivoting parts of the couch a comprehensive lever mechanism is provided. The associated levers are arranged in the side area of the bed. This clearly serves the stability, but has a significant risk of injury. The risk of injury should be prevented by sensors that react when a user accidentally grabs the mechanics with his hands or feet. The sensors, however, involve the problem that they also react to parts other than hands and feet of the couch user in their reaction circle. Any hanging sheet or blanket can make the sensors react. Likewise every person to be admitted and all objects which are too close to the couch. Therefore, it is understandable that the sensor solution could not prevail in practice.

Auch die Erfindung hat sich die Aufgabe gestellt, die Verletzungsgefahr zu beseitigen. Dabei geht die Erfindung einen anderen Weg und von der Erkenntnis aus, dass die Verletzungsgefahr besonders groß ist, wenn die Verstelleinrichtung großvolumig unter der Liege angeordnet ist.
Die Erfindung hat sich die Aufgabe gestellt, die Verletzungsgefahr zu beseitigen. Nach der Erfindung wird das dadurch erreicht, daß die Verstelleinrichtung mit geringern baulichen Volumen unter der Liege angeordnet ist und indem die Verstelleinrichtung auch bei wesentlicher Änderung der Liegenstellung zumindest annähernd die Kontur der Liegenauflagefläche einnimmt.The invention has also taken on the task of eliminating the risk of injury. The invention takes a different approach and from the knowledge that the Danger of injury is particularly great when the adjustment is arranged large volume under the bed.
The object of the invention has been found to eliminate the risk of injury. According to the invention this is achieved in that the adjusting device is arranged with a smaller structural volume under the bed and by the adjustment takes at least approximately the contour of the bed support surface even with significant change in the position of the bed.

Nach der Erfindung wird die Aufgabe mit Verstellmotoren gelöst, die in geringem Abstand in einer Linie unter der Liege angeordnet sind und deren Abstand beim Bewegen der schwenkbeweglichen Teilen im wesentlichen unverändert bleibt.According to the invention, the object is achieved with adjusting motors, which are arranged at a small distance in a line under the bed and whose distance when moving the pivoting parts remains substantially unchanged.

Ein geringer Abstand ist im Sinne der Erfindung ein Abstand von höchstens 30 cm, vorzugsweise von höchstens 20 cm und noch weitere bevorzugt von höchstens 15 cm.A small distance is within the meaning of the invention a distance of at most 30 cm, preferably of at most 20 cm and even more preferably of at most 15 cm.

Ein geringer Abstand wird auch dadurch gewahrt, dass die Verstellmotore in einer Linie hintereinander angeordnet sind und dass die Linie zumindest annähernd der Kontur der Liege oder Bett bei dessen Versstellung folgt.
Das annähernde Folgen schließt im Sinne der Erfindung ein, dass die Längsachse eines Verstellmotors von der Auflagefläche des nächstliegenden schwenkbeweglichen Teiles höchstens 20 Grad abweicht.A small distance is also ensured that the adjusting motors are arranged in a line one behind the other and that the line follows at least approximately the contour of the bed or bed in its adjustment.
The approximate consequences include in the sense of the invention that the longitudinal axis of an adjustment motor deviates from the support surface of the nearest pivotable part by at most 20 degrees.

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.
Anstelle der Selbsthemmung oder zusätzlich kann auch eine mechanische und/oder elektronische bzw. elektrische Arretierung vorgesehen sein. Vorzugsweise ist eine motorische Arretierung vorgesehen.Preferably, adjustable motors are provided with self-locking and / or with locking. The self-locking arises, for example, by using a gear with a spindle or a threaded rod. In this case, for example, a mother can sit on the spindle or threaded rod. It may be arranged drehbewbewlich the spindle or the threaded rod and / or the nut. With the spindle can also interact a gear. In the case of using a gear, at least the spindle or the threaded rod is provided with a drive motor. The self-locking of the spindle or threaded rod is the stronger, the lower the pitch of the spindle or the pitch of the thread on the threaded rod.
Instead of self-locking or in addition, a mechanical and / or electronic or electrical locking can be provided. Preferably, a motor locking is provided.

Wahlweise sind die Spindel bzw. die Gewindestange und/oder die Mutter mit einem Antriebsmotor versehen. Die Antriebsmotore können zugleich eine Arretierung besitzen. Günstig Kind Schrittmotore. Schrittmotore sind im Handel mit Arretierung in der jeweiligen Schrittstellung verfügbar.Optionally, the spindle or the threaded rod and / or the nut are provided with a drive motor. The drive motors can also have a lock at the same time. Cheap child stepping motors. Stepper motors are available in the trade with locking in the respective step position.

Günstig ist auch eine mittige Anordnung der Verstelleinrichtungen unter der Liege oder Bett.Also favorable is a central arrangement of the adjustment under the couch or bed.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawing, an embodiment of the invention is shown.

Fig. 1 bis 4 zeigen eine Liege mit einem Sitzteil 1, einem Beinteil 4, einem Fußteil 5, einem Oberkörperteil 2 und einem Kopfteil 2. Die verschiedenen Teile sind gelenkig miteinander verbunden. Die Gelenke sind im Ausführungsbeispiel herkömmliche Scharniere mit ineinandergreifenden beweglichen Teilen vorgesehen, die durch einen Scharnierbolzen miteinander verbunden sind. In anderen Ausführungsbeispielen sind wahlweise flexible Teile aus Kunststoff oder Federblech als Scharniere vorgesehen.Fig. 1 to 4 show a couch with a seat part 1, a leg part 4, a foot part 5, a upper body part 2 and a head part 2. The various parts are hinged together. The joints are provided in the embodiment conventional hinges with interlocking movable parts which are interconnected by a hinge pin. In other embodiments, optional flexible parts made of plastic or spring steel sheets are provided as hinges.

Das Sitzteil 1 ist zugleich fest mit einer festen Unterkonstruktion verbunden. Die feste Unterkonstruktion besitzt ausschweifende Füße 6 aus Aluminiumprofil. Zur Verringerung des Gewichts ist ein Lochprofil vorgesehen. Im Ausführungsbeispiel sind zwei im Abstand voneinander angeordnete Profile mit einer bogenförmigen Wölbung vorgesehen. Der Bogen hat sein größte Auswölbung im Berührungsbercich mit dem Sitzteil 1. Zu den Enden der Liege hin schwingt der Bogen ab, bis die Profile mit dem Untergrund Berührung finden, Zugleich ist zu den Enden hin eine Verjüngung der Profile vorgesehen.The seat part 1 is also firmly connected to a fixed substructure. The fixed substructure has salient feet 6 made of aluminum profile. To reduce the weight of a hole profile is provided. In the embodiment, two spaced-apart profiles are provided with an arcuate curvature. The arch has its greatest bulge in Berührungsbercich with the seat part 1. To the ends of the lounger, the bow swings off until the profiles find contact with the ground, at the same time a tapering of the profiles is provided to the ends.

An den Teilen 1,2 und 3 sind Teile 10 und 11 vorgesehen. Diese Teile bilden Versteifungen und Lagerkonsolen zur gelenkigen Anbindung von elektrischen Hubmotoren 9.
An dem Fußteil 5 und dem Kopfteil 3 sind gleichfalls Lagerkonsolen vorgesehen, die aber im Ausführungsbeispiel nicht dargestellt sind.
Die Hubmotoren besitzen ein Spindel 12, die durch Drehung aus dem Gehäuse ausgefahren und wieder eingefahren werden kann.
Die Spindeln 12 sind am Kopf gelenkig mit der gegenüberliegenden Teil 10 verbunden, das eine Lagerkonsole bildet. Am anderen Ende der Hubmotore 8 und 9 ist eine gelenkige Verbindung mit den Teilen 10 und 11 vorgesehen.Parts 1, 2 and 3 are provided with parts 10 and 11. These parts form stiffeners and bearing brackets for articulated connection of electric lifting motors 9.
On the foot part 5 and the head part 3 bearing brackets are also provided, which are not shown in the embodiment.
The lifting motors have a spindle 12, which can be extended by rotation out of the housing and retracted.
The spindles 12 are hinged at the head to the opposite part 10, which forms a bearing bracket. At the other end of the Hubmotore 8 and 9, a hinged connection with the parts 10 and 11 is provided.

Alle Hubmotoren sind elektrische Schrittmotore, die in der jeweiligen Sclirittstellung arretiert werden.
Die Hubmotore sind mit einer Schwenkbegrenzung vorgesehen. Die Schwenkbegrenzung erfolgt im Ausführungsbeispiel mittels eines Rechners, wobei die Schrittstellung aufgenommen wird und aus der jeweiligen Schrittstellung die Schwenkstellung ermittelt wird. Das kann empirisch oder anhand der vorhandenen Geometrie der Teile erfolgen, die an der Schwenkbewegung beteiligt sind. Bei der empirischen Ermittlung wird die Schwenkstellung gemessen, welche zu jeder Schrittstellung gehört. Durch Vergleich der zu jeder Schwenkstellung gehörigen Daten kann das weitere Ausfahren eines Hubmotors bzw. das weitere Einfahren eines Hubmotors und eine übermäßige Annäherung der bewegten Teile bzw. ein übermäßiges Auseinanderfahren der bewegten Teile verhindert werden. Dabei wirkt der Rechner im Ausführungsbeispiel auf die Steuerung für die Hubmotore, so daß die Hubmotore nur noch in unschädlicher Richtung bewegt werden können, als in unschädlicher Richtung eingefahren bzw. ausgefahren werden können.All lifting motors are electric stepper motors, which are locked in the respective clamping position.
The Hubmotore are provided with a swivel limitation. The swivel limitation is carried out in the embodiment by means of a computer, wherein the step position is recorded and the pivot position is determined from the respective step position. This can be done empirically or based on the existing geometry of the parts that are involved in the pivoting movement. In the empirical determination, the pivot position is measured, which belongs to each step position. By comparing the data associated with each pivot position, the further extension of a lifting motor or the further retraction of a lifting motor and an excessive approach of the moving parts or an excessive moving apart of the moving parts can be prevented. In this case, the computer acts in the exemplary embodiment of the control for the Hubmotore so that the Hubmotore can only be moved in innocuous direction, as can be retracted or extended in harmless direction.

Die Hubmotore sind im Ausführungsbeispiel so ausgelegt, daß sie in jeder Position der Teile 1 bis 5 eine Verstellung gegen eine Punktbelastung am jeweils entfernten Ende der Teile möglich ist. Dadurch können auch absolut schwergewichtige Personen an beliebiger Stelle der Liege sitzen oder liegen und gleichwohl eine motorische Verstellung der Liege erfolgen.
In einem weiteren Ausführungsbeispiel ist eine Auslegung auf 200 kg vorgesehen, in weiteren Ausführungsbeispielen eine Auslegung auf nur 100 kg vorgesehen.
Unabhängig von der Frage der Verstellkraft sind die Teile 1 bis 5 und die Verstellmechanik so ausgelegt, daß vorkommenden Belastung Stand gehalten wird. Das schließt auch die Auslegung der Unterkonstruktion ein, sowohl hinsichtlich der Festigkeit als auch hinsichtlich der Kippsicherheit.
Die Hubmotore 8 und 9 sind in geringem Abstand von den Teilen 1 bis 5 angeordnet so, daß die Hubmotore in der Seitenansicht der Liege im wesentlichen in einer Linie hintereinander liegen, wobei die Linie in Fig. 4 etwa parallel zur Kontur der Liegenauflagefläche verläuft und wobei die Linie in den Liegenstellungen nach Fig. 1 bis 3 der Kontur der Liegenauflagefläche angepaßt verläuft, d.h. im wesentlichen die gleiche Kontur hat.
Der Begriff "im wesentlichen gleich" umfaßt Abweichungen einer Hubmotorenlängsachse bis zu 20 Grad von der Parallelen zum nächstliegenden Liegenteil bzw. zur Auflagenfläche des nächstliegenden Liegenteils.The Hubmotore are designed in the exemplary embodiment so that it is possible in any position of the parts 1 to 5 an adjustment against a point load at the respective remote end of the parts. As a result, even extremely heavy people can sit or lie anywhere on the bed and still carried out a motorized adjustment of the bed.
In a further embodiment, a design is provided to 200 kg, provided in other embodiments, a design to only 100 kg.
Regardless of the question of adjusting the parts 1 to 5 and the adjustment mechanism are designed so that existing load is maintained. This also includes the design of the substructure, both in terms of strength and in terms of tipping safety.
The Hubmotore 8 and 9 are arranged at a small distance from the parts 1 to 5 so that the Hubmotore lie in a side view of the couch substantially in a line one behind the other, wherein the line in Fig. 4 is approximately parallel to the contour of the couch support surface and wherein the line in the backrest positions according to FIG. 1 to 3 of the contour of the couch support surface is adapted, that is, has substantially the same contour.
The term "substantially equal" includes deviations of a Hubmotorlängsachse up to 20 degrees from the parallels to the nearest lying part or the support surface of the nearest lying part.

Der Abstand der Hubmotoren 8 und 9 beträgt im Ausführungsbeispiel 15 cm, in anderen Ausführungsbeispielen bis 20 cm oder bis 30 cm.
Die beschriebene Bauweise gibt der Verstellmechanik eine vorteilhafte Bodenfreiheit und verringert die Verletzungsgefahr. Dadurch wird verhindert, daß ein Benutzer mit den Füßen in die Verstellmechanik gerät.
Im Ausführungsbeispiel ist die Verstellmechanik außerdem mittig unter der Liege angeordnet, so daß die Verstellmechanik auch für die Hände des Benutzers unzugänglich ist und eine Verletzung der Benutzer an den Händen verhindert wird.The distance of the lifting motors 8 and 9 is in the exemplary embodiment 15 cm, in other embodiments to 20 cm or 30 cm.
The described construction gives the adjustment mechanism a favorable ground clearance and reduces the risk of injury. This prevents a user from getting into the adjustment mechanism with his feet.
In the exemplary embodiment, the adjustment mechanism is also centrally located under the couch, so that the adjustment mechanism is inaccessible to the user's hands and injury to the user is prevented on the hands.

Im Ausführungsbeispiel liegt ein nicht dargestelltes, matrazenförmiges Polster auf den Teilen 1 bis 5 auf und werden das Polster und die Mechanik der Liege (Teile 1 bis 5 und deren Verteilung) mit einem nicht dargestellten Polsterbezug überspannt. Auch das trägt zur Sicherheit bei.
In anderen Ausführungsbeispielen umschließt das Polster die Teile 1 bis 5 und deren Verstellung.In the exemplary embodiment, a mattress-shaped cushion, not shown, rests on the parts 1 to 5 and the upholstery and the mechanism of the couch (parts 1 to 5 and their distribution) are covered with a cushion cover (not shown). That also contributes to safety.
In other embodiments, the pad encloses the parts 1 to 5 and their adjustment.

Bei einer Verstellung wird im Ausführungsbeispiel die weitere Schwenkbewegung der Teile 2 und 4 blockiert, wenn die Teile einen Schwenkwinkel von weniger als 70 Grad zwischen sich einschließen. Die Stellung ist in Fig. 1 und 2 dargestellt. In anderen Ausführungsbeispielen ist ein kleinerer oder größerer eingeschlossener Winkel als Grenzwert gewählt. Durch Änderung der Rechnervorgaben kann der Grenzwert verändert werden.In an adjustment, the further pivotal movement of the parts 2 and 4 is blocked in the embodiment, when the parts include a pivot angle of less than 70 degrees between them. The position is shown in FIGS. 1 and 2. In other embodiments, a smaller or greater included angle is selected as the threshold. By changing the computer default, the limit can be changed.

In Fig. 1 und 2 steht das Fußteil 5 horizontal.In Fig. 1 and 2, the foot part 5 is horizontal.

Der Rechner und die Steuerung verhindern in gleicher Weise wie oben beschrieben auch, daß das Fußteil 5 mit dem Untergrund in Berührung kommt. In anderen Ausführungsbeispielen ist noch ein Sicherheitsabstand zwischen dem Ende des Fußteiles 5 und dem Untergrund vorgesehen, so daß ein versehentlich unter das Fußteil 5 geratener Fuß nicht verletzt wird.The computer and the controller prevent in the same way as described above, that the foot part 5 comes into contact with the ground. In other embodiments, a safety distance between the end of the foot part 5 and the ground is still provided, so that accidentally under the foot part 5 advised foot is not injured.

Fig. 3 zeigt eine Liegenstellung, in der beide Teile 4 und 5 horizontal stehen.Fig. 3 shows a position in which both parts 4 and 5 are horizontal.

Fig. 4 zeigt eine Liegenstellung in der alle Teile 1 bis 5 horizontal stehen.Fig. 4 shows a position in which all parts 1 to 5 are horizontal.
