Zunächst sei auf Fig. 1 sowie 1a bis 1g Bezug genommen, in denen der grundsätzliche Aufbau eines Ausführungsbeispiels des erfindungsgemäßen Kinderhochstuhls erläutert ist. Der im Ganzen mit 1 bezeichnete Kinderhochstuhl weist ein Fußteil 2 und ein Sitzelement 4 auf, die durch eine dazwischen angeordnete Gasdruckfeder 6 drehbar und höhenverstellbar miteinander verbunden sind.First be up Fig. 1 and 1a to 1g, in which the basic structure of an embodiment of the high chair according to the invention is explained. The high chair designated as a whole by 1 has a foot part 2 and a seat element 4, which are connected to one another in a rotatable and height-adjustable manner by a gas pressure spring 6 arranged between them.

Das Fußteil 2 ist in der dargestellten Ausführungsform im wesentlichen aus einem Ring 8 aus gebogenem Metallrohr und einem damit fest verbundenen Querelement 10 aus Kunststoff aufgebaut, auf dem mittig ein Halteteil 12 mit einer zylindrischen Aufnahmeöffnung 14 zur Aufnahme eines unteren Endabschnitts der Gasdruckfeder 6 angeordnet ist.In the embodiment shown, the foot part 2 is essentially composed of a ring 8 made of bent metal tube and a transverse element 10 made of plastic firmly connected to it, on which a holding part 12 with a cylindrical receiving opening 14 for receiving a lower end portion of the gas pressure spring 6 is arranged in the center.

Das Sitzelement 4 ist in der dargestellten Ausführungsform im wesentlichen aus einer Sitzschale 20 mit darin aufgenommener Sitzauflage 22 aufgebaut, wobei die Sitzschale 20 seitlich an zwei näherungsweise viertelkreisförmig gebogenen Tragarmen 24 gehalten ist. Die Tragarme 24 sind an einem Anschlussteil 26 miteinander verbunden, welches gleichzeitig der Verbindung mit einem oberen Endabschnitt der Gasdruckfeder 6 dient. Eine Fußstütze 30 ist an der Sitzschale 20 lösbar gehalten.In the embodiment shown, the seat element 4 is essentially composed of a seat shell 20 with a seat support 22 received therein, the seat shell 20 being held laterally on two support arms 24 bent approximately in the shape of a quarter circle. The support arms 24 are connected to one another at a connection part 26 which at the same time serves to connect to an upper end section of the gas pressure spring 6. A footrest 30 is detachably held on the seat shell 20.

An oberen Endabschnitten der Tragarme 24 ist weiterhin ein Tisch 32 lösbar angebracht, von dem aus sich eine Sicherheitsstütze 34 abwärts bis zu einem vorderen Rand der Sitzschale 20 erstreckt und lösbar mit dieser verbunden ist.A table 32 is also detachably attached to the upper end portions of the support arms 24, from which a safety support 34 extends down to a front edge of the seat shell 20 and is detachably connected to it.

Fig. 2 und 3 erläutern die Höhenverstellbarkeit des Kinderhochstuhls 1 mehr im einzelnen. Aus der Gasdruckfeder 6 steht an deren oberem Endabschnitt ein Betätigungsvorsprung 40 vor (Fig. 2a), der in niedergedrücktem Zustand (Fig. 3a) eine Höhen -bzw. Längenverstellung der Gasdruckfeder 6 ermöglicht. Hierfür ist ein auf den Betätigungsvorsprung 40 wirkendes abgewinkeltes Druckelement 42 vorgesehen, welches mit einem horizontalen mittleren Abschnitt 44 auf dem Betätigungsvorsprung 40 aufliegt und zwei schräg nach unten abgewinkelte Endabschnitte 46 aufweist. Auf jedem Tragarm 24 ist ein Bedienelement 48 verschieblich angeordnet und mit einem Ende eines Seil- oder Drahtzugs 50 verbunden, der an seinem anderen Ende im Bereich des Druckelements 42 jeweils mit einem keilförmigen Gleitelement 52 verbunden ist. Figs. 2 and 3 explain the height adjustability of the high chair 1 in more detail. An actuating projection 40 protrudes from the gas pressure spring 6 at its upper end section ( Fig. 2a ), which when depressed ( Fig. 3a ) a height or Adjustment of the length of the gas pressure spring 6 allows. For this purpose, an angled pressure element 42 acting on the actuating projection 40 is provided, which rests with a horizontal central section 44 on the actuating projection 40 and has two end sections 46 angled downwards at an angle. An operating element 48 is arranged displaceably on each support arm 24 and is connected to one end of a cable or wire pull 50, which is at its other end Each end in the area of the pressure element 42 is connected to a wedge-shaped sliding element 52.

Wenn beide Bedienelemente 48 gleichzeitig nach oben gezogen werden, wie in Fig. 3 mit Pfeilen 54 angedeutet ist, werden die Gleitelemente 52 durch die Drahtzüge 50 in Richtung auf den mittleren Abschnitt 44 des Druckelements 42 zu einander gezogen und drücken dadurch, weil sie im Bereich ihrer Oberseite an einer ebenen Führungsfläche 56 abgestützt sind, das Druckelement 42 nach unten (Pfeil 58).If both controls 48 are pulled up at the same time, as in Fig. 3 is indicated by arrows 54, the sliding elements 52 are pulled towards each other by the wire pulls 50 in the direction of the central section 44 of the pressure element 42 and thereby press the pressure element 42 downwards because they are supported in the area of their upper side on a flat guide surface 56 (Arrow 58).

Durch die Verwendung von zwei separat wirkenden Drahtzügen 50 und eines abgewinkelten Druckelements 42 ist eine Zweihand-Sicherheitsbedienung gebildet, die verhindert, dass die Höhenverstellung in unerwünschter Weise durch ein in dem Kindersitz befindliches Kleinkind betätigt wird (Betätigung nur eines Drahtzugs genügt nicht).By using two separately acting wire pulls 50 and an angled pressure element 42, a two-hand safety control is formed which prevents the height adjustment from being actuated in an undesired manner by a small child in the child seat (actuation of only one wire pull is not sufficient).

Fig. 2 und 3 zeigen ferner die Halterung des oberen Endabschnitts der Gasdruckfeder 6 in dem Verbindungsteil 26 des Sitzelements 4. In dem Verbindungsteil 26 sind zwei mit gegenseitigem Abstand angeordnete buchsenartige Aufnahmeelemente 60 angeordnet, deren Innendurchmesser dem Aussendurchmesser der Gasdruckfeder 6 entspricht, und eine mit einem Handgriff versehene Befestigungsschraube 62 kann seitlich gegen die Gasdruckfeder 6 angezogen werden, um eine Verspannung und Fixierung herzustellen. Figs. 2 and 3 also show the mounting of the upper end portion of the gas pressure spring 6 in the connecting part 26 of the seat element 4. In the connecting part 26, two spaced-apart socket-like receiving elements 60 are arranged, the inner diameter of which corresponds to the outer diameter of the gas pressure spring 6, and a fastening screw 62 provided with a handle can be tightened sideways against the gas pressure spring 6 in order to produce tension and fixation.

Fig. 4 und 5 erläutern grundsätzlich die Möglichkeit, das Sitzelement 4 bzw. die Sitzschale 20 um eine horizontale Querachse 70 zu verschwenken und auf diese Weise die Neigung der Sitzschale einzustellen. Hierfür ist ein von Hand bedienbares Betätigungselement 72 rückseitig an der Sitzschale angeordnet. Figures 4 and 5 basically explain the possibility of pivoting the seat element 4 or the seat shell 20 about a horizontal transverse axis 70 and in this way adjusting the inclination of the seat shell. For this purpose, an actuating element 72 which can be operated by hand is arranged on the rear of the seat shell.

Fig. 6 und Einzelheiten nach Fig. 6a bis 6d erläutern die Verriegelung der Sitzschale in einer gewünschten Neigung. Die Sitzschale 20 ist mit zwei seitlichen, die Querachse 70 festlegenden Achszapfen 74 versehen, in denen Längsnuten 76 ausgebildet sind. Auf jedem Achszapfen 74 ist ein Drehverriegelungselement 78 axial verschieblich angeordnet und greift mit radial nach innen gerichteten Vorsprüngen in die Längsnuten 74, so dass es drehfest mit dem Achszapfen 74 verbunden ist. Das Drehverriegelungselement 78 ist weiterhin mit Verriegelungszähnen 80 versehen, mit denen es formschlüssig mit komplementären Verriegelungsvorsprüngen oder -zähnen in Eingriff treten kann, die innenseitig in einer Lagerhülse 82 ausgebildet sind, die ihrerseits fest mit dem jeweiligen Tragarm 24 verbunden ist. Zwischen dem Drehverriegelungselement 78 und der Lagerhülse 82 ist auf der einen Seite eine schraubenförmige Rückstellfeder 84 und auf der anderen Seite ein Drehnockenelement 86 angeordnet, welches mit drei keilförmig ansteigenden Nocken oder Führungsflächen 88 versehen ist, die über seinen Umfang verteilt angeordnet sind. Das Drehverriegelungselement 78 ist in nicht dargestellter Weise mit Gegenflächen versehen, die mit den Nocken 88 zusammenwirken. Fig. 6 and details after Figures 6a to 6d explain the locking of the seat shell in a desired inclination. The seat shell 20 is provided with two lateral axle journals 74 which fix the transverse axis 70 and in which longitudinal grooves 76 are formed. A rotary locking element 78 is arranged axially displaceably on each axle journal 74 and engages with radially inwardly directed projections in the longitudinal grooves 74, so that it is connected to the axle journal 74 in a rotationally fixed manner. The twist lock member 78 continues to have locking teeth 80, with which it can engage with complementary locking projections or teeth in a form-fitting manner, which are formed on the inside in a bearing sleeve 82, which in turn is firmly connected to the respective support arm 24. Between the rotary locking element 78 and the bearing sleeve 82 a helical return spring 84 is arranged on one side and a rotary cam element 86 on the other side, which is provided with three wedge-shaped rising cams or guide surfaces 88 which are arranged distributed over its circumference. The rotary locking element 78 is provided, in a manner not shown, with opposing surfaces which interact with the cams 88.

Das Drehnockenelement 86 ist drehbar auf dem Achszapfen 74 angeordnet und mit dem Bedienelement 72 durch ein geeignetes Betätigungsmittel verbunden, in diesem Beispiel durch einen Drahtzug 90. Zweckmäßigerweise ist die in Fig. 6a bis 6d gezeigte Drehverriegelungsanordnung in gleicher Weise auf beiden Seiten der Sitzschale 20 vorhanden.The rotary cam element 86 is rotatably arranged on the axle journal 74 and is connected to the operating element 72 by a suitable actuating means, in this example by a wire pull 90 Figures 6a to 6d The rotary locking arrangement shown is provided in the same way on both sides of the seat shell 20.

Bei einer Betätigung des Bedienelements 72 in Richtung des Pfeils 92 wird das Drehnockenelement 86 um einen vorgegebenen Winkelbetrag verdreht und verschiebt dadurch das drehfest auf dem Achszapfen 74 geführte Drehverriegelungselement 78 entgegen der Kraft der Rückstellfeder 84 nach aussen in Richtung des Pfeils 94. Die Verriegelungszähne 80 des Drehverriegelungselements 78 treten dadurch ausser Eingriff mit den Verriegelungszähnen der Lagerhülse 82, so dass die Sitzschale 20 frei um die Querachse 70 verschwenkt werden kann. Bei Erreichen einer gewünschten Neigung wird das Bedienelement 72 losgelassen, und die Rückstellfeder 84 bringt das Drehverriegelungselement 78 erneut in Verriegelungseingriff mit der Lagerhülse 82, so dass auch der Achszapfen 74 und damit die Sitzschale 20 unverdrehbar gegenüber den Tragarmen 24 gehalten ist.When the operating element 72 is actuated in the direction of arrow 92, the rotary cam element 86 is rotated by a predetermined angular amount and thereby displaces the rotary locking element 78, which is non-rotatably guided on the journal 74, outwardly in the direction of arrow 94 against the force of the return spring 84 Rotary locking elements 78 thereby disengage from the locking teeth of the bearing sleeve 82, so that the seat shell 20 can be pivoted freely about the transverse axis 70. When a desired inclination is reached, the operating element 72 is released, and the return spring 84 brings the rotary locking element 78 again into locking engagement with the bearing sleeve 82, so that the axle pin 74 and thus the seat shell 20 are held non-rotatably with respect to the support arms 24.

Fig. 7 und 7a bis 7f erläutern, in welcher Weise das Sitzelement des Kinderhochstuhls gegenüber dem Fußteil um eine vertikale Achse 96 drehbar und feststellbar gehalten ist. Zu diesem Zwecke ist in bzw. an dem Halteteil 12 des Fußteils 2 ein C-förmiger Klemmring 100 vorgesehen, dessen einander gegenüberliegende Enden mittels einer Kniehebel- oder Übertodpunkthebelanordnung in Richtung zueinander verspannt werden können. Die Kniehebelanordnung ist in der dargestellten Ausführungsform aus einem Spannhebel 102 und einem Betätigungshebel 104 aufgebaut, die mit dem Klemmring 100 sowie miteinander schwenkbar verbunden sind. Figures 7 and 7a to 7f explain the way in which the seat element of the high chair is held rotatable and lockable about a vertical axis 96 relative to the foot part. For this purpose, a C-shaped clamping ring 100 is provided in or on the holding part 12 of the foot part 2, the opposite ends of which can be clamped in the direction of one another by means of a toggle lever or over-dead-point lever arrangement. In the embodiment shown, the toggle lever arrangement is constructed from a tensioning lever 102 and an actuating lever 104, which are pivotably connected to the clamping ring 100 and to one another.

In der in Fig. 7a, 7b, 7d, 7e dargestellten Stellung ist der Klemmring 100 fest auf dem unteren Endabschnitt der Gasdruckfeder 6 verspannt, so dass sich diese und das Sitzelement 4 nicht relativ zu dem Fußteil 2 verdrehen kann. Wird der Betätigungshebel 104 gelöst (Fig. 7c, 7f) gibt der Klemmring 100 die Gasdruckfeder 6 frei, und das Sitzelement 4 kann verdreht werden.In the in Figures 7a, 7b, 7d, 7e In the position shown, the clamping ring 100 is firmly clamped on the lower end section of the gas pressure spring 6, so that the latter and the seat element 4 cannot rotate relative to the foot part 2. If the operating lever 104 is released ( Figures 7c, 7f ) the clamping ring 100 releases the gas pressure spring 6 and the seat element 4 can be rotated.

Ein in Umfangsrichtung verschieblicher Sicherheitsschieber 106 nimmt federbelastet seine in Fig. 7a, 7d dargestellte Ausgangsstellung ein, in der der Betätigungshebel 104 nicht hintergriffen werden kann, so dass eine unbeabsichtigte Betätigung durch Kinder verhindert wird. Erst eine Zurückbewegung des Sicherheitsschiebers 106 in Richtung des Pfeils 108 (Fig. 7b,7e) ermöglicht ein Öffnen des Betätigungshebels 104.A safety slide 106 displaceable in the circumferential direction takes its spring-loaded into Figures 7a, 7d A starting position shown, in which the actuating lever 104 cannot be grasped from behind, so that unintentional actuation by children is prevented. Only a return movement of the safety slide 106 in the direction of the arrow 108 ( Figures 7b, 7e ) enables the actuation lever 104 to be opened.

Fig. 8 und 8a bis 8d erläutern die Befestigung des Tischs 32 an den Tragarmen 24. Wie Fig. 8c zeigt, weist der Tisch 32 zwei hakenförmige Befestigungsansätze 120 auf, die innenseitig mit zwei Arretierungsvorsprüngen 122 und, diesen gegenüberliegend, mit einer nicht näher dargestellten Arretierungsvertiefung, deren Lage mit 124 angedeutet ist, versehen sind. Die an den oberen Enden der Tragarme 24 gehaltenen Lagerhülsen 82 sind aussenseitig mit nutartigen Vertiefungen 126 versehen, in die die Befestigungsansätze 120 einzusetzen sind. Figures 8 and 8a to 8d explain the attachment of the table 32 to the support arms 24. How Figure 8c shows, the table 32 has two hook-shaped fastening lugs 120 which are provided on the inside with two locking projections 122 and, opposite these, with a locking recess, not shown in detail, the position of which is indicated by 124. The bearing sleeves 82 held at the upper ends of the support arms 24 are provided on the outside with groove-like depressions 126 into which the fastening lugs 120 are to be inserted.

In jeder Lagerhülse 82 ist ein federbelastetes Rastelement 130 (Fig. 8b) verschieblich gelagert, das einen Rastvorsprung 132 trägt und mit einem Druckknopf 134 von aussen betätigbar ist, so dass der Rastvorsprung in die Lagerhülse 82 zurückbewegbar ist.In each bearing sleeve 82 there is a spring-loaded locking element 130 ( Figure 8b ) mounted displaceably, which carries a latching projection 132 and can be actuated from the outside with a push button 134, so that the latching projection can be moved back into the bearing sleeve 82.

Beim Aufsetzen der Befestigungsansätze 120 auf die Lagerhülsen 82 bzw. in die Vertiefungen 126 greifen die Arretierungsvorsprünge 122 in entsprechende Vertiefungen (nicht dargestellt) in der Lagerhülse 82 ein, und die Rastvorsprünge 132 rasten in die Arretierungsvertiefungen 124 ein, so dass der Tisch fest an den Tragarmen 24 gehalten ist. Zum Lösen werden die Druckknöpfe 134 betätigt, so dass sich die Rastvorsprünge 132 zurückziehen und die Befestigungsansätze 120 gelöst werden können.When the fastening lugs 120 are placed on the bearing sleeves 82 or in the recesses 126, the locking projections 122 engage in corresponding recesses (not shown) in the bearing sleeve 82, and the locking projections 132 snap into the locking recesses 124, so that the table is firmly attached to the Support arms 24 is held. To release the pushbuttons 134 are actuated so that the latching projections 132 retract and the fastening lugs 120 can be released.

Fig. 9 und 9a bis 9d erläutern die Befestigung der Sicherheitsstütze 34, die mit einem Rastfuß 140 in einer Rastaufnahme 142 der Sitzschale fixiert werden kann. Wie Fig. 9d zeigt, ist ein in die dargestellte verriegelte Ausgangsposition federvorgespanntes Druckknopfelement 144 vorgesehen, welches mit zwei seitlichen Endabschnitten 146 aus dem Rastfuß 140 vorsteht. Eine in der Rastaufnahme 142 ausgebildete Einlaufschräge 148 mit einer dahinter angeordneten Einrastvertiefung 150 ermöglicht ein selbsttätiges Verriegeln des Rastfußes beim Einschieben in die Rastaufnahme 142. Durch Niederdrücken des Druckknopfelements 144 werden die Endabschnitte 146 aus den Einrastvertiefungen 150 gelöst, und der Rastfuß 140 kann aus der Rastaufnahme 142 herausgezogen werden. Figures 9 and 9a to 9d explain the fastening of the safety support 34, which can be fixed with a locking foot 140 in a locking receptacle 142 of the seat shell. How Figure 9d shows is a spring-biased push-button element 144 is provided in the locked starting position shown, which protrudes with two lateral end sections 146 from the locking foot 140. An inlet bevel 148 formed in the latching receptacle 142 with a latching recess 150 arranged behind it enables the latching foot to be automatically locked when it is pushed into the latching receptacle 142. By pressing down the push-button element 144, the end sections 146 are released from the latching recesses 150, and the latching foot 140 can be removed from the latching receptacle 142 can be pulled out.

Da der Tisch 32 unabhängig von dem jeweils eingestellten Neigungswinkel der Sitzschale horizontal bleibt, wird die Sicherheitsstütze 34 zweckmäßigerweise längenveränderbar ausgebildet, was vorliegend durch eine teleskopierbare Bauform erreicht wird. Alternativ könnte ein elastisches Material vorgesehen sein.Since the table 32 remains horizontal regardless of the respectively set angle of inclination of the seat shell, the safety support 34 is expediently designed to be variable in length, which is achieved in the present case by means of a telescopic design. Alternatively, an elastic material could be provided.

Die Fußstütze 30 ist ebenfalls längenveränderbar ausgebildet, zweckmäßigerweise durch zwei ineinandergreifende, teleskopartig verlagerbare Teile. Auch hier kann ein Klemm- oder Rastmittel zur Fixierung einer gewählten Länge zweckmäßig sein.
