Abstract

A joint (2) for members (3, 14) defining a suction passage (15) of a vacuum cleaner has one member (14) with pivot pins (4) projecting from opposite sides and another member (3) assembled from two parts (5, 6) around them. The pivot pins have spring elements (10) projecting radially, and parts (9) of these cooperate with detents (13) in an annular cavity (12) formed by the other member (3) so that, as the joint is tilted, the spring element (10) snaps in and out of the detents (13). The joint can thus be adjustably set at any of a number of positions, without any externally operated catch. A swivel joint may also be provided in passage (15). <IMAGE>

Description

       

  
 



  Die Erfindung bezieht sich auf einen Gelenkstutzen an einer Staubsaugerdüse. 



  Bei Staubsaugerdüsen und Zusatzgeräten sind neben dem starren Anschlussstutzen zum Anschluss des Saugrohres noch der Kippgelenkstutzen, der Drehgelenkstutzen und der Drehkippgelenkstutzen, bestehend aus einem Kippgelenk, verbunden mit einem Drehgelenkstutzen, bekannt. 



  Für verschiedene Handhabungsbereiche ist es erforderlich, das Gelenk bzw. den Stutzen in einer bestimmten Winkelstellung einzurasten oder festzustellen. In der Ruhestellung und zum Transport von Einsatzort zu Einsatzort wird bei Hand- und Stielstaubsaugern vorzugsweise die Einrastung des Kippgelenkes senkrecht zur Arbeitsfläche gewählt. 



  Rastelemente für Gelenke sind als Stand der Technik in vielen Variationen bekannt. Die meist unter Federdruck stehenden Sperrklinken, Bolzen, Nocken oder Zähne werden mittels Hand- oder Fussbetätigung ein- und ausgerastet. Der Raumbedarf ist bei diesen Bauarten jedoch relativ gross;  auch bestehen derartige Rastelemente aus mehreren Einzelteilen und sind durch den zusätzlichen Montageaufwand nicht kostengünstig zu fertigen. 



  Der Erfindung liegt die Aufgabe zugrunde, einen Gelenkstutzen an einer Staubsaugerdüse zu schaffen, dessen Aufbau und Montage einfach ist, so dass er kostengünstig zu fertigen und ausserdem auch leicht zu handhaben ist. 



  Die Lösung dieser Aufgabe erfolgt gemäss dem Kennzeichnungsteil des Anspruchs 1 in Verbindung mit dessen Oberbegriff. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Merkmalen der Ansprüche 2 und 3. 



  Nachstehend ist eine bevorzugte Ausführungsform der Erfindung mit Bezug auf die schematischen Zeichnungen beispielsweise näher beschrieben; es zeigen: 
 
   Fig. 1 eine Drehkippgelenkdüse im Schnitt; 
   Fig. 2 eine Kippgelenkdüse im Schnitt an einem Staubsaugerzusatzgerät; 
   Fig. 3 einen Schnitt durch das erfindungsgemässe Rastelement in vergrösserter Darstellung; 
   Fig. 4 einen Kippgelenkstutzen und 
   Fig. 5 einen Schnitt durch den Kippgelenkstutzen. 
 



  In den Fig. 1 und 2 ist jeweils ein Drehkippgelenk 1 bzw. ein Kippgelenk 2 an einer Staubsaugerdüse 3 im Schnitt dargestellt. Beide sind mit ihren Lagerzapfen 4, die beidseitig, also links und rechts an einem Gelenkkopf 14 angeformt sind, in der Staubsaugerdüse 3 gelagert. Dabei besteht die Düse zweckmässigerweise aus einem Oberteil 5 und einem Unterteil 6, wobei die Trennebene 7 mittig durch diesen Lagerzapfen 4 verläuft. 



  An den beiden, aussen rechts und links vom Saugdurchlass (15) angeordneten Lagerzapfen (4) des aus hochwertigem Kunststoff bestehenden Gelenks sind Einrastnasen (9) an einem Federelement (10) vorgesehen, wobei Einrastnase (9), Federelement (10) und Lagerzapfen (4) einstückig ausgebildet sind, so dass das Federelement (10) in radialer Richtung aus- und einfedern kann. 



  Das Gehäuse weist zentrisch um die Lagerzapfenaufnahmen (11) eine ringförmige Ausnehmung (12) auf, in der das Federelement (10) gleiten kann. Im Umfang der Ausnehmung (12) sind eine oder mehrere Einrastnuten (13) angeordnet, in welche die Einrastnase (9) einschnappt. Die Lagerzapfenaufnahmen (11) und die ringförmige Ausnehmung (12) sind ebenfalls entlang der Trennebene (7) geteilt und dem Oberteil (5) sowie dem Unterteil (6) zugeordnet. 



  Der Lage der Einrastnase (9) am Gelenkkopf (14) entsprechen vorbestimmte Lagen der Einrastnuten (13) in der ringförmigen Ausnehmung (12), so dass sich, wie in den Fig. 1 und 2 gezeigt, drei Raststellungen des Gelenkkopfes (14) - waagrecht, 45 DEG und senkrecht - ergeben. 



  Um für das Ein- und Ausrasten von Nasen (9) und Nuten (13) in beiden Drehrichtungen den gleichen Kraftaufwand sowie Funktionssicherheit zu gewährleisten, ist die Einrastnase (9) beidseitig an dem Federelement (10) angebunden, wodurch dieses ein etwa U-förmiges Aussehen erhält. Das Federelement (10) besteht aus zwei vom Lagerzapfen (4) ausgehenden speichenartigen Armen (16), die an ihrem Ende mit einem Bogen (17) einstückig sind, in dessen Mitte die Einrastnase (9) sitzt; dabei entspricht der Aussenradius des Bogens (17) dem Innenradius der Ausnehmung (12). Die Arme (16) sind etwa im Winkel von 90 DEG  zueinander angeordnet. Beim Einrasten wird, wie Fig. 5 zeigt, der Bogen (17) zum Zentrum und die Arme (16) werden nach aussen gedrückt. Die  Raststellung ist strichpunktiert dargestellt.

   Der Kraftaufwand zum Ein- und Ausrasten kann durch entsprechendes Auslegen des Federelementes (10), d.h. die Stärke der Arme (16) und des Bogens (17) gewählt werden. 



  Gemäss Fig. 1 ist der Drehgelenkstutzen (18) im Kippgelenk drehbar und unlösbar angebracht und dient zur Aufnahme des Saugrohrs (19). 



  Nach Fig. 2 ist das Saugrohr (19) direkt in das Kippgelenk (2) einsteckbar. 



  Durch diese Lösung der Rastung kann auf alle zusätzlichen, von aussen zu bedienenden Rast- oder Entrastelemente verzichtet werden. Ausserdem ist durch die Einstückigkeit von Kippgelenk und Rastung eine einfache, kostengünstige Fertigung möglich, wodurch auch die Montage vereinfacht ist. 



  
 



  The invention relates to a joint socket on a vacuum cleaner nozzle.



  In the case of vacuum cleaner nozzles and additional devices, in addition to the rigid connecting piece for connecting the suction pipe, the tilting joint piece, the rotating joint piece and the rotating and tilting piece piece, consisting of a tilting piece connected to a rotating piece piece, are known.



  For different handling areas, it is necessary to lock or fix the joint or the socket in a certain angular position. In the rest position and for transport from place of use to place of use, the snap-in joint of the tilt joint perpendicular to the work surface is preferably selected for hand and stick vacuum cleaners.



  Locking elements for joints are known in many variations as prior art. The pawls, bolts, cams or teeth, which are usually under spring pressure, are engaged and disengaged by hand or foot operation. The space required for these types is relatively large; Such locking elements also consist of several individual parts and are not inexpensive to manufacture due to the additional assembly effort.



  The invention has for its object to provide a hinge connector on a vacuum cleaner nozzle, the construction and assembly is simple, so that it is inexpensive to manufacture and also easy to use.



  This object is achieved in accordance with the characterizing part of claim 1 in conjunction with its preamble. Advantageous developments of the invention result from the features of claims 2 and 3.



  A preferred embodiment of the invention is described in more detail below with reference to the schematic drawings, for example; show it:
 
   Figure 1 shows a rotary tilt joint nozzle in section.
   2 shows a tilting joint nozzle in section on a vacuum cleaner attachment;
   3 shows a section through the locking element according to the invention in an enlarged representation;
   Fig. 4 a tilt joint and
   Fig. 5 shows a section through the tilt joint.
 



  1 and 2 each show a rotary tilt joint 1 or a tilt joint 2 on a vacuum cleaner nozzle 3 in section. Both are mounted with their journals 4, which are formed on both sides, that is to say on the left and right on a joint head 14, in the vacuum cleaner nozzle 3. The nozzle expediently consists of an upper part 5 and a lower part 6, the parting plane 7 running centrally through this journal 4.



  On the two bearing pins (4) of the joint made of high-quality plastic and arranged on the outside right and left of the suction passage (15), snap-in lugs (9) are provided on a spring element (10), with snap-in lug (9), spring element (10) and bearing pin ( 4) are formed in one piece, so that the spring element (10) can rebound and compress in the radial direction.



  The housing has an annular recess (12) centrally around the bearing journal receptacles (11) in which the spring element (10) can slide. One or more latching grooves (13) are arranged in the periphery of the recess (12), into which the latching lug (9) snaps. The bearing journals (11) and the annular recess (12) are also divided along the parting plane (7) and assigned to the upper part (5) and the lower part (6).



  The position of the latching lug (9) on the joint head (14) corresponds to predetermined positions of the latching grooves (13) in the annular recess (12), so that, as shown in FIGS. 1 and 2, three latching positions of the joint head (14) horizontal, 45 ° and vertical - result.



  In order to ensure the same amount of force as well as functional reliability for the engagement and disengagement of lugs (9) and grooves (13) in both directions of rotation, the engagement lug (9) is connected to the spring element (10) on both sides, whereby this is approximately U-shaped Appearance. The spring element (10) consists of two spoke-like arms (16) extending from the bearing journal (4), which at the end are integral with an arc (17), in the middle of which the latching lug (9) sits; the outer radius of the arc (17) corresponds to the inner radius of the recess (12). The arms (16) are arranged at an angle of approximately 90 ° to one another. When latching, as shown in FIG. 5, the arch (17) is pushed towards the center and the arms (16) are pressed outwards. The locking position is shown in dash-dot lines.

   The effort required to engage and disengage can be adjusted by appropriately laying out the spring element (10), i.e. the strength of the arms (16) and the bow (17) can be selected.



  According to Fig. 1, the swivel joint (18) is rotatably and non-detachably attached in the tilt joint and serves to receive the suction pipe (19).



  2, the suction pipe (19) can be inserted directly into the tilt joint (2).



  With this solution of the latching, all additional latching or unlatching elements to be operated from the outside can be dispensed with. In addition, the one-piece articulation of the tilt joint and detent enables simple, cost-effective production, which also simplifies assembly.
