Durch ein Fixier-Element 31 ist die Position eines Stütz-Rohrs 7 gegenüber einem Seitenteil 3 festlegbar. Durch die Anlenkung des Rohr-Körpers 15 im hinteren Bereich der Auflage-Abschnitte an den Stütz-Rohren 7 sind der Rohr-Körper 15 mit den Aufnahmen 19, der Sitz 4 und die Rückenlehne 24 aus der in Fig. 1 dargestellten Stellung nach hinten verschwenkbar. Die entsprechende Schwenk-Achse verläuft unter dem Sitz 4. An jedem Auflage-Abschnitt und einem unteren End-Abschnitt des benachbarten Stütz-Rohrs 7 ist jeweils eine Gasdruck-Feder 32 zur Unterstützung der Schwenk-Bewegung angelenkt. Ausgehend von der Verbindung zwischen dem Rohr-Körper 15 und den Stütz-Rohren 7 ist die Gasdruck-Feder 32 weiter vorne an den Auflage-Abschnitten angelenkt. Die beiden Gasdruck-Federn 32 sind über einen Bedien-Hebel betätigbar, der an dem Griff-Abschnitt 28 befestigt ist und über Bowdenzüge mit den Gasdruck-Federn 32 in Verbindung steht.The tube body 15 is articulated in the region of its support sections on the support tubes 7, which in corresponding recesses of the Side parts 3 are guided displaceably. By displacing the support tubes 7, the tube body 15 with the receptacles 19, the seat 4 and the backrest 24 can be adjusted together in height. By a fixing element 31, the position of a support tube 7 relative to a side part 3 can be fixed. By the articulation of the tube body 15 in the rear region of the support sections on the support tubes 7 of the tube body 15 with the receptacles 19, the seat 4 and the backrest 24 of the in Fig. 1 shown position pivoted backwards. The respective pivot axis extends under the seat 4. At each support portion and a lower end portion of the adjacent support tube 7 is in each case a gas pressure spring 32 articulated to support the pivoting movement. Based on the connection between the tube body 15 and the support tubes 7, the gas pressure spring 32 is articulated further forward of the support sections. The two gas pressure springs 32 are actuated via an operating lever, which is attached to the handle portion 28 and is connected via Bowden cables with the gas pressure springs 32 in connection.

Die mit dem Rohr-Körper 15 in Verbindung stehenden Aufnahmen 19 sind für die Lagerung einer linken und einer rechten Fußstütze 34 vorgesehen. Die Fußstützen 34 sind identisch ausgebildet. Auf eine Fußstütze 34 und deren Einzelteile wird nachfolgend auch unter Bezugnahme auf die beigefügten Fig. 2 bis 10 näher eingegangen.The associated with the pipe body 15 receptacles 19 are provided for the storage of a left and a right foot rest 34. The footrests 34 are identical. On a footrest 34 and its items is below with reference to the accompanying Fig. 2 to 10 discussed in more detail.

Die Fußstütze 34 umfasst ein einstückiges Trag-Rohr 35 aus Edelstahl, mit welchem über einen einstückigen Kunststoff-Lager-Körper 36 eine KunstStoff-Fußplatte 37 in Verbindung steht. Die Fußplatte 37 ist ebenfalls einstückig ausgebildet. Sie ist für den Fuß eines Rollstuhl-Patienten vorgesehen.The footrest 34 comprises a one-piece support tube 35 made of stainless steel, with which an artificial material base plate 37 is connected via an integral plastic bearing body 36. The foot plate 37 is also integrally formed. It is intended for the foot of a wheelchair patient.

Das im Querschnitt kreisringförmig ausgebildete Trag-Rohr 35 umfasst einen geraden Einführ-Abschnitt 38, dessen Außen-Durchmesser in etwa dem Durchmesser der Aufnahme-Ausnehmung der Aufnahme 19 entspricht. Die Länge des Einführ-Abschnitts 38 stimmt in etwa mit der Tiefe der Aufnahme-Ausnehmung überein. In dem dem freien Ende 39 des Einführ-Abschnitts 38 benachbarten Bereich befindet sich eine Ausrichtungs-Ausnehmung 40, die U-förmig ist und nach unten offen ist. Der Einführ-Abschnitt 38 dient zur Einführung in die Aufnahme-Ausnehmung der Auf nahme 19. Er bzw. die Fußstütze 34 ist in der Aufnahme-Ausnehmung um eine im Wesentlichen vertikale Schwenk-Achse verschwenkbar. In der Vorderseite der Aufnahme 19 sind mehrere übereinander angeordnete Positionierungs-Öffnungen 44 vorgesehen, in welche der Schaft eines Stahl-Bolzens 45 einsteckbar ist. Der Durchmesser des Schafts des Stahl-Bolzens 45 entspricht in etwa der Öffnungs-Breite einer Ausrichtungs-Ausnehmung 40, so dass im montierten Zustand einer Fußstütze 34 an dem Rollstuhl 1 der Schaft des Stahl-Bolzens 45 zumindest teilweise in der Ausrichtungs-Ausnehmung 40 sitzen kann. Durch diesen Eingriff wird ein unerwünschtes Verschwenken der Fußstütze 34 aus der in Fig. 1 gezeigten Transport-Stellung verhindert. Zum Verschwenken der Fußstütze 34 ist der Einführ-Abschnitt 38 etwas anzuheben, so dass der Stahl-Bolzen 45 und die Ausrichtungs-Ausnehmung 40 außer Eingriff gelangen. Der Stahl-Bolzen 45 ist in eine Kunststoff-Klammer 46 eingebettet, die den Stahl-Bolzen 45 an der Aufnahme 19 in der entsprechenden Positionierungs-Öffnung 44 hält. Die Höhe der Fußplatte 37 ist durch die Wahl der Positionierungs-Öffnung 44 wählbar.The circular cross-section formed in the support tube 35 comprises a straight insertion section 38 whose outer diameter corresponds approximately to the diameter of the receiving recess of the receptacle 19. The length of the insertion portion 38 is approximately equal to the depth of the receiving recess. In the region adjacent the free end 39 of the insertion section 38, there is an alignment recess 40 which is U-shaped and open at the bottom. He or the footrest 34 is pivotable about a substantially vertical pivot axis in the receiving recess. In the front of the receptacle 19 a plurality of superimposed positioning openings 44 are provided, in which the shank of a steel bolt 45 can be inserted. The diameter of the shaft of the steel bolt 45 corresponds approximately to the opening width of an alignment recess 40, so that in the mounted state of a footrest 34 on the wheelchair 1, the shank of the steel bolt 45 at least partially seated in the alignment recess 40 can. By this intervention, an undesirable pivoting of the footrest 34 from the in Fig. 1 shown transport position prevented. For pivoting the footrest 34, the insertion portion 38 is slightly raised, so that the steel bolt 45 and the alignment recess 40 are disengaged. The steel bolt 45 is embedded in a plastic clip 46 which holds the steel bolt 45 to the receptacle 19 in the corresponding positioning aperture 44. The height of the foot plate 37 can be selected by the choice of the positioning hole 44.

Außerdem ist die Längs-Ausnehmung 61 auf die äußere Stirnfläche 52 des Außenteils 51 hin offen. Sie wird durch zwei, einander gegenüberliegende, zueinander parallele, gerade Begrenzungs-Wände 62 und eine die Begrenzungs-Wände 62 miteinander verbindende Verbindungs-Wand 63 begrenzt. Die Verbindungs-Wand 63 ist zu dem Innenteil 50 hin gekrümmt.In the outer part 51 extends centrally, based on the width of the outer part 51, a continuous longitudinal recess 61 whose width and depth corresponds approximately to the outer diameter of the bearing portion 43 of the support tube 35. The longitudinal recess 61 passes through the upper portion 56 and the lower portion 57, that is, it is open at the top and bottom. In addition, the longitudinal recess 61 is open to the outer end face 52 of the outer part 51. It is bounded by two, mutually parallel, straight boundary walls 62 and a connecting wall 63 interconnecting the boundary walls 62. The connecting wall 63 is curved toward the inner part 50.

Das Außenteil 51 wird außerdem von einer Lager-Ausnehmung 64 durchsetzt, die sich oberhalb der Wendelinien 60 in den Lager-Abschnitten 58 befindet. Die Lager-Ausnehmung 64 verläuft senkrecht zu der Längs-Ausnehmung 61 und weist über einen ersten Abschnitt, der sich von der Mantelfläche 54 bis zu der einen Begrenzungs-Wand 62 der Längs-Ausnehmung 61 erstreckt, einen kreisförmigen Querschnitt auf (siehe Fig. 4 rechts). Im Bereich der Mantelfläche 54 entspricht der Durchmesser dieses ersten Abschnitts in etwa dem Durchmesser des Kopfs des Gewinde-Bolzens 47, während im Bereich der Begrenzungs-Wand 62 der Durchmesser dieses ersten Abschnitts ungefähr mit dem Durchmesser des Schafts des Gewinde-Bolzens 47 übereinstimmt. Der der Mantelfläche 54 benachbarte Bereich dieses ersten Abschnitts ist zur Aufnahme des Kopfs des Gewinde-Bolzens 47 vorgesehen, während der der Begrenzungs-Wand 62 benachbarte Abschnitt für den Schaft des Gewinde-Bolzens 47 ausgebildet ist. Über einen zweiten Abschnitt weist die Lager-Ausnehmung 64 einen sechseckigen Querschnitt auf (siehe Fig. 4 links). Dieser zweite Abschnitt erstreckt sich von der anderen Begrenzungs-Wand 62 bis zu der Mantelfläche 54. Der Querschnitt des zweiten Abschnitts der Lager-Ausnehmung 64 entspricht in etwa der Außenform der Mutter 49. Die Mutter 49 kann in dem zweiten Abschnitt der Lager-Ausnehmung 64 formschlüssig aufgenommen werden. Unterhalb der Lager-Ausnehmung 64 befinden sich zwei einander gegenüberliegende, längliche Aussparungen 66, die lediglich zu der Mantelfläche 54 hin offen sind. Jede Aussparung 66 erstreckt sich von einem Lager-Abschnitt 58 bis in einen Anlage-Abschnitt 59 hinein.The outer part 51 is also penetrated by a bearing recess 64 which is located above the turning lines 60 in the bearing sections 58. The bearing recess 64 extends perpendicular to the longitudinal recess 61 and has a circular cross-section over a first portion which extends from the lateral surface 54 to the one boundary wall 62 of the longitudinal recess 61 (see Fig. 4 right). In the region of the lateral surface 54, the diameter of this first section corresponds approximately to the diameter of the head of the threaded bolt 47, while in the region of the boundary wall 62, the diameter of this first section approximately matches the diameter of the shaft of the threaded bolt 47. The area of this first section adjacent to the lateral surface 54 is provided for receiving the head of the threaded bolt 47, while the boundary wall 62 adjacent section is formed for the shaft of the threaded bolt 47. Over a second portion, the bearing recess 64 has a hexagonal cross-section (see Fig. 4 Left). This second section extends from the other boundary wall 62 to the lateral surface 54. The cross section of the second portion of the bearing recess 64th corresponds approximately to the outer shape of the nut 49. The nut 49 can be positively received in the second portion of the bearing recess 64. Below the bearing recess 64 are two opposing, elongated recesses 66, which are open only to the lateral surface 54 out. Each recess 66 extends from a bearing portion 58 into an abutment portion 59.

Das Innenteil 50 ist über ein Hals-Teil 67 mit dem Außenteil 51 verbunden und springt gegenüber dem Hals-Teil 67 über eine Anlage-Schulter 68 vor, die im Wesentlichen parallel zu den Stirnflächen 52, 53 verläuft. Das Hals-Teil 67 ist gegenüber den Lager-Abschnitten 58, den Anlage-Abschnitten 59 und dem oberen Abschnitt 56 des Außenteils 51 nach innen versetzt. Die Grundform des Innenteils 50 entspricht in etwa der Grundform des Außenteils 51. Die Breite, Dicke und Höhe des Innenteils 50 ist jedoch kleiner als die Breite, Dicke und Höhe des Außenteils 51. Das Innenteil 50 weist eine Mantelfläche 69 mit einem unteren, geraden Abschnitt 70 auf, an welchen sich beidseitig jeweils ein gerader Anlage-Abschnitt 71 anschließt. Die Anlage-Abschnitte 71 gehen in gekrümmte Lager-Abschnitte 72 über. Die Lager-Abschnitte 72 sind nach außen gekrümmt. Zwischen den beiden Lager-Abschnitten 72 befindet sich ein nach oben offener, nach innen gekrümmter Bogen-Abschnitt 73, dessen Krümmungs-Radius in etwa dem Radius des Lager-Abschnitts 43 des Trag-Rohrs 35 bzw. der Breite der Längs-Ausnehmung 61 entspricht. Das Innenteil 50 erweitert sich, ausgehend von dem unteren Abschnitt 70, im Bereich der Anlage-Abschnitte 71 konstant bis zu den Lager-Abschnitten 72. Im Bereich der Lager-Abschnitte 72 erweitert sich dann das Innenteil 50 bis zu entsprechenden Wendelinien 74; anschließend verjüngt sich das Innenteil 50 bis zu dem Bogen-Abschnitt 73. Ein Anlage-Abschnitt 71 des Innenteils 50 verläuft in etwa parallel zu dem entsprechenden Anlage-Abschnitt 59 des Außenteils 51. Die Krümmung der Lager-Abschnitte 72 des Innenteils 50 entspricht ungefähr der Krümmung der Lager-Abschnitte 58 des Außenteils 51.The inner part 50 is connected via a neck part 67 to the outer part 51 and projects relative to the neck part 67 via a contact shoulder 68, which extends substantially parallel to the end faces 52, 53. The neck portion 67 is offset inwardly from the bearing portions 58, abutment portions 59, and upper portion 56 of the outer portion 51. However, the width, thickness and height of the inner part 50 are smaller than the width, thickness and height of the outer part 51. The inner part 50 has a lateral surface 69 with a lower, straight section 70, which is followed on both sides in each case by a straight contact section 71. The plant sections 71 merge into curved bearing sections 72. The bearing portions 72 are curved outwardly. There is an upwardly open, inwardly curved arc section 73, whose radius of curvature corresponds approximately to the radius of the bearing portion 43 of the support tube 35 and the width of the longitudinal recess 61 between the two bearing sections 72 , The inner part 50 expands, starting from the lower section 70, in the area of the abutment sections 71, constantly up to the bearing sections 72. In the area of the bearing sections 72, the inner section 50 then widens to corresponding turning lines 74; Subsequently, the inner part 50 tapers to the arc section 73. An abutment portion 71 of the inner part 50 extends approximately parallel to the corresponding abutment portion 59 of the outer part 51. The curvature of the bearing sections 72 of the inner part 50 corresponds approximately to the curvature of the bearing sections 58 of the outer part 51.

Das Innenteil 50 weist außerdem mittig - bezogen auf die Breite des Lager-Körpers 36 - eine durchgängige Lager-Ausnehmung 75 auf, die senkrecht zu der Längs-Ausnehmung 61 und der Lager-Ausnehmung 64 verläuft. Die Lager-Ausnehmung 75 erstreckt sich unterhalb der Lager-Ausnehmung 64. Sie ist endseitig jeweils offen und mündet in der Längs-Ausnehmung 61. Im Bereich des Innenteils 50 ist die Lager-Ausnehmung 75 kreisförmig. Im Bereich des Hals-Teils 67 weist die Lager-Ausnehmung 75 dagegen eine Sechseckform auf.The inner part 50 also has centrally - based on the width of the bearing body 36 - a continuous bearing recess 75 which extends perpendicular to the longitudinal recess 61 and the bearing recess 64. The bearing recess 75 extends below the bearing recess 64. It is each end open and opens into the longitudinal recess 61. In the region of the inner part 50, the bearing recess 75 is circular. In contrast, in the region of the neck portion 67, the bearing recess 75 has a hexagonal shape.

Der Lager-Körper 36 weist zu einer das Innenteil 50 und Außenteil 51 halbierenden Ebene eine symmetrische Grundform auf. Diese Ebene erstreckt sich mittig durch die Längs-Ausnehmung 61 sowie die Lager-Ausnehmung 75 und ist senkrecht zu der Lager-Ausnehmung 64. In Figur 5 verläuft sie im Wesentlichen vertikal.The bearing body 36 has a symmetrical basic shape to a plane bisecting the inner part 50 and the outer part 51. This plane extends centrally through the longitudinal recess 61 and the bearing recess 75 and is perpendicular to the bearing recess 64. In FIG. 5 it is essentially vertical.

Die Fußplatte 37 ist mit dem Lager-Körper 36 verschraubt. Hierzu ist ein Gewinde-Bolzen 76 und eine entsprechende Mutter 77 vorgesehen. Der kreisförmige Bereich der Lager-Ausnehmung 75 weist einen Durchmesser auf, der in etwa dem Durchmesser des Schafts des Gewinde-Bolzens 76 entspricht. Dieser Bereich der Lager-Ausnehmung 75 ist zur Aufnahme des Schafts des Gewinde-Bolzens 76 vorgesehen. Die Gestalt und Abmessung des sechseckigen Bereichs der Lager-Ausnehmung 75 ist dagegen an die Mutter 77 angepasst, die dort formschlüssig aufgenommen werden kann.The foot plate 37 is bolted to the bearing body 36. For this purpose, a threaded bolt 76 and a corresponding nut 77 is provided. The circular region of the bearing recess 75 has a diameter which corresponds approximately to the diameter of the shaft of the threaded bolt 76. This region of the bearing recess 75 is provided for receiving the shank of the threaded bolt 76. The shape and dimension of the hexagonal portion of the bearing recess 75, however, adapted to the nut 77, which can be accommodated there form-fitting manner.

Die Fußplatte 37 umfasst einen Fuß-Auflage-Teil 78 für den Fuß eines Rollstuhl-Patienten und einen Lager-Teil 79, der sich seitlich an dem Fuß-Auflage-Teil 78 anschließt. Der Fuß-Auflage-Teil 78 weist eine ebene Fuß-Auflage-Platte 80 auf, um welche entlang deren beiden Längs-Ränder 81 und ihres freien Quer-Randes 82 ein Rahmen 83 verläuft. Der Rahmen 83 erstreckt sich von der Fuß-Auflage-Platte 80 nach unten. Von der Fuß-Auflage-Platte 80 springen außerdem vier Versteifungs-Streben 84 nach unten vor. Auf der Oberseite der Fuß-Auflage-Platte 80 befindet sich eine Vielzahl von runden Anti-Rutsch-Vorsprüngen 85, die von der Fuß-Auf lage-Platte 80 vorstehen. In den durch die Längs-Ränder 81 und den freien Quer-Rand 82 gebildeten Eck-Bereichen der Fuß-Auflage-Platte 80 befinden sich zwei Befestigungs-Ausnehmungen 86, die die Fuß-Auflage-Platte 80 von oben nach unten durchdringen. In jeweils eine Befestigungs-Ausnehmung 86 einer Fußplatte 37 ist ein End-Abschnitt eines Gewinde-Bolzens zur Anbringung einer Rückwand einzuführen. Die Rückwand ist außerdem noch an dem Lager-Abschnitt 43 befestigt und verhindert, dass der Fuß des Rollstuhl-Patienten von der Fuß-Auflage-Platte 80 nach hinten abrutscht.The foot plate 37 includes a footrest portion 78 for the foot of a wheelchair patient and a bearing portion 79 which adjoins the footrest portion 78 laterally. The foot rest portion 78 has a flat foot rest plate 80 about which a frame 83 extends along the two longitudinal edges 81 and its free transverse edge 82. The frame 83 extends downwardly from the footrest plate 80. In addition, four stiffener struts 84 project downwardly from the footrest plate 80. On the top of the foot rest plate 80 is a plurality of round anti-skid projections 85 projecting from the foot-on-plate 80. In the corner areas formed by the longitudinal edges 81 and the free transverse edge 82 of the foot rest plate 80 are two mounting recesses 86 which penetrate the foot rest plate 80 from top to bottom. In each case a fastening recess 86 of a foot plate 37 is to introduce an end portion of a threaded bolt for attachment of a rear wall. The rear wall is also still attached to the bearing portion 43 and prevents the foot of the wheelchair patient from slipping off the footrest plate 80 to the rear.

Der Lager-Teil 79 der Fußplatte 37 ist gegenüber dem Fuß-Auflage-Teil 78 erhöht. Er weist eine dem Fuß-Auflage-Teil 78 zugewandte Seitenfläche 87, eine der Seitenfläche 87 gegenüberliegende Seitenfläche 88 und zwei die Seitenflächen 87, 88 verbindende Seitenflächen 89 auf. In dem Lager-Teil 79 ist eine Lager-Aussparung 90 ausgebildet, die nach oben und unten sowie nach außen hin offen ist. Die Lager-Aussparung 90 umfasst einen inneren Lager-Bereich 91 für das Innenteil 50 und einen äußeren Lager-Bereich 92 für das Außenteil 51. Der innere Lager-Bereich 91 befindet sich näher an dem Fuß-Auflage-Teil 78 als der äußere Lager-Bereich 92. Der innere Lager-Bereich 91 ist durch eine Seitenwand 93, zwei von dieser senkrecht verlaufende Seitenwände 94 und zwei Halte-Vorsprünge 95, die von den Seitenwänden 94 nach innen vorspringen und parallel zu der Seitenwand 93 verlaufen, gebildet. Die Seitenwand 93 ist eben ausgebildet und verläuft in etwa senkrecht zu der Fuß-Auflage-Platte 80. Die Seitenwände 94 weisen jeweils einen unteren, geraden Anlage-Abschnitt 96 auf, die parallel zueinander verlaufen. An jeden Anlage-Abschnitt 96 schließt sich ein nach außen gekrümmter Lager-Abschnitt 97 an. Die Krümmung eines Lager-Abschnitts 97 ist im Wesentlichen an die Krümmung eines Lager-Abschnitts 72 des Innenteils 50 des Lager-Körpers 36 angepasst. Der innere Abstand der Seitenwände 94 des inneren Lager-Bereichs 91 zueinander entspricht in etwa der Breite des Innenteils 50 des Lager-Körpers 36 im Bereich der Wendelinien 74, das heißt, der Abstand der Seitenwände 94 zueinander entspricht ungefähr der größten Breiten-Abmessung des Innenteils 50. Die Halte-Vorsprünge 95 sind entsprechend an das Hals-Teil 67 des Lager-Körpers 36 angepasst. Der Verlauf eines Halte-Vorsprungs 95 entspricht in etwa dem Verlauf der Seitenwand 94, das heißt, auch er weist einen geraden unteren Abschnitt 98 und einen gekrümmten Abschnitt 99 auf.The bearing part 79 of the foot plate 37 is raised relative to the foot rest part 78. It has a side surface 87 facing the foot support part 78, a side surface 88 opposite the side surface 87, and two side surfaces 89 connecting the side surfaces 87, 88. In the bearing part 79, a bearing recess 90 is formed, which is open at the top and bottom and to the outside. The bearing recess 90 comprises an inner bearing region 91 for the inner part 50 and an outer bearing region 92 for the outer part 51. The inner bearing region 91 is located closer to the foot rest part 78 than the outer bearing part 91. Area 92. The inner bearing area 91 is defined by a side wall 93, two of these vertically extending side walls 94 and two retaining projections 95 which project inwardly from the side walls 94 and extend parallel to the side wall 93 formed. The side wall 93 is planar and extends approximately perpendicular to the foot rest plate 80. The side walls 94 each have a lower, straight abutment portion 96, which are parallel to each other. Each plant section 96 is followed by an outwardly curved bearing section 97. The curvature of a bearing portion 97 is substantially matched to the curvature of a bearing portion 72 of the inner portion 50 of the bearing body 36. The inner distance of the side walls 94 of the inner bearing portion 91 to each other corresponds approximately to the width of the inner part 50 of the bearing body 36 in the region of the turning lines 74, that is, the distance of the side walls 94 to each other approximately corresponds to the largest width dimension of the inner part 50. The retaining projections 95 are adapted to the neck portion 67 of the bearing body 36 accordingly. The course of a holding projection 95 corresponds approximately to the course of the side wall 94, that is, it also has a straight bottom portion 98 and a curved portion 99. Der Winkelabschnitt 99 ist in Fig. 1 dargestellt.

Der innere Lager-Bereich 91 ist unten vollständig offen. Außerdem weist der innere Lager-Bereich 91 oben eine Öffnung auf, die zwischen den Lager-Abschnitten 97 verläuft. Die untere Öffnung des inneren Lager-Bereichs 91 weist eine größere Öffnungs-Breite als die obere Öffnung auf. Im Bereich der oberen Öffnung weist die Seitenwand 93 eine gleichmäßig nach innen gekrümmte Aussparung 100 auf, deren Krümmungs-Radius in etwa dem Radius des Lager-Abschnitts 43 des Trag-Rohrs 35 entspricht. An jeden Halte-Vorsprung 95 schließt sich eine Anlagewand 101 an, die parallel zu der Seitenwand 93 verläuft und eine in etwa konstante Breite aufweist. Die Aussparung 100 trennt jeweils die Lager-Abschnitte 97, die gekrümmten Abschnitte 99 der Halte-Vorsprünge 95 und die oberen, direkt benachbarten Abschnitte der Anlagewände 101 voneinander. An jede Anlagewand 101 grenzt eine Seitenwand 102 an, die senkrecht auf der Anlagewand 101 steht und in die Seitenfläche 88 übergeht. Jede Seitenwand 102 weist ebenfalls einen unteren, geraden Anlage-Abschnitt 103 und einen oberen, gekrümmten Lager-Abschnitt 104 auf. Die Anlage-Abschnitte 103 der Seitenwände 102 verlaufen parallel zueinander. Die Seitenwände 102 und die Anlagewände 101 mit den Halte-Vorsprüngen 95 sind im Wesentlichen an die Grundform des Außenteils 51 des Lager-Körpers 36 angepasst. Die Krümmung eines Lager-Abschnitts 104 entspricht in etwa der Krümmung eines Lager-Abschnitts 58 des Außenteils 51 des Lager-Körpers 36. Die Breite einer Seitenwand 102 entspricht in etwa der Breite der Mantelfläche 54 des Außenteils 51.The inner bearing portion 91 is fully open at the bottom. In addition, the inner bearing portion 91 at the top has an opening extending between the bearing portions 97. The lower opening of the inner bearing portion 91 has a larger opening width than the upper opening. In the region of the upper opening, the side wall 93 has a uniformly inwardly curved recess 100 whose radius of curvature corresponds approximately to the radius of the bearing portion 43 of the support tube 35. Each support projection 95 is followed by a contact wall 101, which runs parallel to the side wall 93 and has an approximately constant width. The recess 100 separates the bearing sections 97, the curved portions 99 of the retaining projections 95 and the upper, directly adjacent portions of the abutment walls 101 from each other. Adjacent to each abutment wall 101 is a side wall 102, which is perpendicular to the abutment wall 101 and merges into the side surface 88. Each sidewall 102 also has a lower, straight abutment portion 103 and an upper, curved bearing portion 104. The abutment portions 103 of the side walls 102 are parallel to each other. The side walls 102 and the abutment walls 101 with the retaining projections 95 are substantially adapted to the basic shape of the outer part 51 of the bearing body 36. The curvature of a bearing portion 104 corresponds approximately to the curvature of a bearing portion 58 of the outer part 51 of the bearing body 36. The width of a side wall 102 corresponds approximately to the width of the lateral surface 54 of the outer part 51st

Die Seitenwand 93 und die Seitenfläche 87 der Fußplatte 37 sind von einer Lager-Ausnehmung 105 durchdrungen, die parallel zu der Fuß-Auflage-Platte 80 verläuft und kreisförmig ausgebildet ist. Die Lager-Ausnehmung 105 ist mittig, bezogen auf die Breite der Seitenwand 93, angeordnet. Der Durchmesser der Lager-Ausnehmung 105 entspricht in etwa dem Durchmesser des Schafts des Gewinde-Bolzens 76.The side wall 93 and the side surface 87 of the foot plate 37 are penetrated by a bearing recess 105 which is parallel to the foot rest plate 80 and is circular in shape. The bearing recess 105 is centrally, based on the width of the side wall 93, arranged. The diameter of the bearing recess 105 corresponds approximately to the diameter of the shaft of the threaded bolt 76.

Die Fußplatte 37 ist bezüglich einer Ebene symmetrisch, die mittig durch die Lager-Aussparung 90 und die Lager-Ausnehmung 105 verläuft und senkrecht auf der Fuß-Auflage-Platte 80 steht.The foot plate 37 is symmetrical with respect to a plane which passes centrally through the bearing recess 90 and the bearing recess 105 and is perpendicular to the foot rest plate 80.

Wie bereits erwähnt, ist das Trag-Rohr 35 mit dem Lager-Körper 36 verschraubt. Hierzu durchdringt der Schaft des Gewinde-Bolzens 47 die Lager-Ausnehmung 64 in dem Lager-Körper 36 und die Ausnehmung 48 in dem Trag-Rohr 35. Der Schaft des Gewinde-Bolzens 47 steht dabei mit der Mutter 49 in Gewinde-Eingriff, die in dem entsprechend ausgebildeten Abschnitt der Lager-Ausnehmung 64 sitzt. In diesem Abschnitt ist eine Drehung der Mutter 49 gegenüber dem Lager-Körper 36 nicht möglich. Der Lager-Körper 36 ist an dem Trag-Rohr 35 um den Schaft des Gewinde-Bolzens 47 verschwenkbar. Der Gewinde-Bolzen 47 bildet also ein Lager-Element zur verschwenkbaren Lagerung des Lager-Körpers 36 bzw. der Fußplatte 37 an dem Trag-Rohr 35. Die Verschwenkung erfolgt um die Längs-Mittel-Achse des Gewinde-Bolzens 47, die gemäß Fig. 1 im Wesentlichen horizontal verläuft.As already mentioned, the support tube 35 is bolted to the bearing body 36. For this purpose, the shaft of the threaded bolt 47 penetrates the bearing recess 64 in the bearing body 36 and the recess 48 in the support tube 35. The shaft of the threaded bolt 47 stands with the Nut 49 in threaded engagement, which sits in the correspondingly formed portion of the bearing recess 64. In this section, a rotation of the nut 49 relative to the bearing body 36 is not possible. The bearing body 36 is pivotable on the support tube 35 about the shank of the threaded bolt 47. The threaded bolt 47 thus forms a bearing element for the pivotable mounting of the bearing body 36 and the foot plate 37 on the support tube 35. The pivoting takes place about the longitudinal center axis of the threaded bolt 47, according to Fig. 1 essentially horizontally.

Der Lager-Körper 36 ist in der Lager-Aussparung 90 der Fußplatte 37 angeordnet. Die äußere Stirnfläche 52 des Lager-Körpers 36 fluchtet in der horizontalen Stellung der Fußplatte 37 mit der Seitenfläche 88 der Fußplatte 37. Das Innenteil 50 des Lager-Körpers 36 befindet sich in dem inneren Lager-Bereich 91 der Fußplatte 37, während das Außenteil 51 in dem äußeren Lager-Bereich 92 angeordnet ist. Die Abschnitte 58, 59 des Lager-Körpers 36 sind den Seitenwänden 102 der Fußplatte 37 zugewandt und berühren diese teilweise, während die Abschnitte 71, 72 des Lager-Körpers 36 den Seitenwänden 94 zugewandt sind und an diesen teilweise anliegen. Die Vorsprünge 95 greifen im Bereich des Hals-Teils 67 in den Lager-Körper 36 ein und verhindern, dass sich der Lager-Körper 36 in der Lager-Aussparung 90 nach innen oder außen bewegt. Die Anlagewände 101 berühren die Stirnfläche 53.The bearing body 36 is disposed in the bearing recess 90 of the foot plate 37. The outer end surface 52 of the bearing body 36 is aligned in the horizontal position of the foot plate 37 with the side surface 88 of the foot plate 37. The inner part 50 of the bearing body 36 is located in the inner bearing portion 91 of the base plate 37, while the outer part 51st is disposed in the outer bearing portion 92. The portions 58, 59 of the bearing body 36 are the side walls 102 of the base plate 37 facing and partially touching, while the portions 71, 72 of the bearing body 36, the side walls 94 facing and partially abut against these. The projections 95 engage the bearing body 36 in the region of the neck portion 67 and prevent the bearing body 36 from moving inwardly or outwardly in the bearing recess 90. The abutment walls 101 touch the end face 53.

Der Schaft des Gewinde-Bolzens 76 durchsetzt die Lager-Ausnehmung 105 der Fußplatte 37 und die Lager-Ausnehmung 75 des Lager-Körpers 36. Der Gewinde-Bolzen 76 steht dabei mit der Mutter 77 in Gewinde-Eingriff, die in dem entsprechend ausgebildeten Abschnitt der Lager-Ausnehmung 75 sitzt. Eine Drehung der Mutter 77 gegenüber dem Lager-Körper 36 ist dabei nicht möglich. Der Gewinde-Bolzen 76 bildet ein Lager-Element zur verschwenkbaren Lagerung der Fußplatte 37 an dem Lager-Körper 36. Die Verschwenkung erfolgt um die Längs-Mittel-Achse des Gewinde-Bolzens 76, die im Wesentlichen horizontal verläuft.The shaft of the threaded bolt 76 passes through the bearing recess 105 of the base plate 37 and the bearing recess 75 of the bearing body 36. The threaded pin 76 is in threaded engagement with the nut 77 in the correspondingly formed section the bearing recess 75 is seated. A rotation of the nut 77 relative to the bearing body 36 is not possible. The threaded bolt 76 forms a bearing element for pivotally supporting the foot plate 37 on the bearing body 36. The pivoting takes place about the longitudinal center axis of the threaded bolt 76, which extends substantially horizontally.

Im Folgenden wird die Funktion der Fußstütze 34 bzw. das Zusammenspiel der einzelnen Teile der Fußstütze 34 näher beschrieben. Die Fußplatte 37 ist zum einen zwischen einer in Fig. 1 bzw. Fig. 6 dargestellten, herabgeklappten, horizontalen Stellung und einer in Fig. 9 dargestellten, hochgeklappten, vertikalen Stellung verschwenkbar. Diese Verschwenkung nach oben bzw. unten erfolgt um den Schaft des Gewinde-Bolzens 47, der gemäß Fig. 1 in einer im Wesentlichen horizontalen Ebene verläuft. Das zum Verschwenken erforderliche Moment ist durch das Anzugsmoment des Gewinde-Bolzens 47 einstellbar. Durch ein entsprechendes Festziehen des Gewinde-Bolzens 47 kann der Lager-Körper 36 und damit auch die Fußplatte 37 in jeder beliebigen Schwenk-Stellung festgelegt werden. Im festgezogenen Zustand drückt die Mutter 49 gegen das Trag-Rohr 35. Der Lager-Körper 36 wird dabei an dem Trag-Rohr 35 festgeklemmt. Da die Mutter 49 in der Lager-Ausnehmung 64 nicht verdrehbar ist, muss die Mutter 49 beim Anziehen des Gewinde-Bolzens 47 nicht extra gehalten werden. Es wird bevorzugt, dass die Fußplatte 37 so festgelegt wird, dass sie durch Aufbringen eines entsprechenden Bedien-Moments auf die Fußplatte 37 beweglich bleibt. Dieses Bedien-Moment ist durch Anziehen des Gewinde-Bolzens 47 einstellbar.The function of the footrest 34 or the interaction of the individual parts of the footrest 34 will be described in more detail below. The foot plate 37 is on the one hand between an in Fig. 1 respectively. Fig. 6 shown, folded down, horizontal position and one in Fig. 9 shown, folded, vertical position pivoted. This pivoting upwards or downwards takes place about the shank of the threaded bolt 47, which according to FIG Fig. 1 in a substantially horizontal plane. The moment required for pivoting is adjustable by the tightening torque of the threaded bolt 47. By a corresponding tightening of the threaded bolt 47 of the bearing body 36 and thus also the base plate 37 can be set in any pivot position. In the tightened state, the nut 49 presses against the support tube 35. The bearing body 36 is thereby clamped to the support tube 35. Since the nut 49 is not rotatable in the bearing recess 64, the nut 49 when tightening the threaded bolt 47 need not be kept extra. It is preferred that the foot plate 37 be fixed so as to remain movable by applying a corresponding operating torque to the foot plate 37. This operating torque is adjustable by tightening the threaded bolt 47.

In der herabgeklappten Schwenk-Position der Fußplatte 37 verläuft ein End-Abschnitt des Lager-Abschnitts 43 in der Längs-Ausnehmung 61 des Lager-Körpers 36. Der End-Abschnitt erstreckt sich über die gesamte Länge der Längs-Ausnehmung 61. Es liegt hier also ein großflächiger Kontakt zwischen den Begrenzungs-Wänden 62 und dem End-Abschnitt des Lager-Abschnitts 43 vor. Der Durchmesser des Lager-Abschnitts 43 des Trag-Rohrs 35 bzw. die Tiefe der Längs-Ausnehmung 61 des Lager-Körpers 36 ist - wie bereits erwähnt - so gewählt, dass der Lager-Abschnitt 43 nicht seitlich aus dem Lager-Körper 36 vorsteht. In der heraufgeschwenkten Stellung der Fußplatte 37 liegt ein Bereich des Lager-Abschnitts 43 in dem entsprechend ausgebildeten Bogen-Abschnitt 73 des Lager-Körpers 36.
Der Bogen-Abschnitt 73 ermöglicht, dass die Fußplatte 37 nahezu vertikal hochgeklappt werden kann und bildet einen die Verschwenkung begrenzenden Anschlag.In the folded down pivot position of the base plate 37, an end portion of the bearing portion 43 extends in the longitudinal recess 61 of the bearing body 36. The end portion extends over the entire length of the longitudinal recess 61. It lies here So a large-scale contact between the restricting walls 62 and the end portion of the bearing portion 43. The diameter of the bearing portion 43 of the support tube 35 and the depth of the longitudinal recess 61 of the bearing body 36 is - as already mentioned - chosen so that the bearing portion 43 does not protrude laterally from the bearing body 36 , In the raised position of the base plate 37 is a portion of the bearing portion 43 in the correspondingly formed arc portion 73 of the bearing body 36th
The bow portion 73 allows the foot plate 37 to be folded up almost vertically and forms a pivot limiting abutment.

Die Fußplatte 37 ist außerdem um eine weitere Schwenk-Achse verschwenkbar, die durch den Schaft des Gewinde-Bolzens 76 gebildet ist. Diese Verschwenkbarkeit ist am besten in den Fig. 7 und 8 dargestellt. Bezogen auf Fig. 1 ist ein Verschwenken der Fußplatten 37 nach vorne bzw. nach hinten möglich. Die Lager-Abschnitte 58 und 72 des Lager-Körpers 36 führen dabei die Fußplatte 37 über ihre entsprechend angepaßten Lager-Abschnitte 97, 104. In Fig. 8 ist eine End-Stellung der Fußplatte 37 dargestellt. In einer End-Stellung der Fußplatte 37 liegen die entsprechenden Anlage-Abschnitte 59, 71 des Lager-Körpers 36 an den entsprechenden Anlage-Abschnitten 96, 103 der Fußplatte 37 flächig an. Das Betätigungs-Moment zur Verschwenkung der Fußplatte 37 kann auch hier durch das Anzugsmoment des Gewinde-Bolzens 76 eingestellt werden. Eine Arretierung in einer beliebigen Schwenk-Position ist ebenfalls durch entsprechendes Anziehen des Gewinde-Bolzens 76 möglich. In der arretierten Stellung werden der Lager-Körper 36 und die Fußplatte 37 durch den Kopf des Gewinde-Bolzens 76 und die Mutter 77 zusammengedrückt. Die Fußplatte 37 wird also an dem Lager-Körper 36 festgeklemmt. Durch die entsprechende Ausgestaltung der Lager-Ausnehmung 75 muss die Mutter 77 beim Anziehen des Gewinde-Bolzens 76 nicht gehalten werden.The foot plate 37 is also pivotable about a further pivot axis which is formed by the shank of the threaded bolt 76. This pivotability is best in the FIGS. 7 and 8 shown. Related to Fig. 1 is a pivoting of the foot plates 37 forward or backward possible. The bearing sections 58 and 72 of the bearing body 36 thereby guide the base plate 37 via their correspondingly adapted bearing portions 97, 104. In Fig. 8 an end position of the foot plate 37 is shown. In an end position of the foot plate 37 are the corresponding abutment portions 59, 71 of the bearing body 36 to the corresponding abutment portions 96, 103 of the base plate 37 to surface. The actuation torque for pivoting the foot plate 37 can also be adjusted by the tightening torque of the threaded bolt 76 here. A lock in any pivot position is also possible by tightening the threaded bolt 76 accordingly. In the locked position, the bearing body 36 and the foot plate 37 are compressed by the head of the threaded bolt 76 and the nut 77. The foot plate 37 is thus clamped to the bearing body 36. By the corresponding configuration of the bearing recess 75, the nut 77 must not be held when tightening the threaded bolt 76.

Die Lager-Aussparung 90 weist oben eine Einlaufschräge 106 auf, so dass ein Hochklappen der Fußplatte 37 in allen nach vorne bzw. nach hinten geschwenkten Stellungen möglich ist.The bearing recess 90 has at the top an inlet bevel 106, so that a folding up of the foot plate 37 in all forward or backward pivoted positions is possible.

Die Fußplatte 37 ist also durch die Lager-Einheit um zwei SchwenkAchsen verschwenkbar, die senkrecht zueinander und horizontal verlaufen. Hierdurch kann die Fußplatte 37 optimal an einen Rollstuhl-Patienten eingestellt werden.The base plate 37 is thus pivotable about two pivot axes by the bearing unit, which are perpendicular to each other and horizontal. As a result, the foot plate 37 can be optimally adjusted to a wheelchair patient.

Anstelle der verwendeten Muttern 49, 77 ist es auch möglich, entsprechende Gewinde direkt in dem Lager-Körper 36 auszubilden.Instead of the nuts 49, 77 used, it is also possible to form corresponding threads directly in the bearing body 36.
