Description
Die Erfindung betrifft einen Staubsauger mit Handgriff und Adapter, der an seinem einen Ende den Endbereich eines Staubsaugersaugrohres und an seinem anderen Ende einen Rohrstutzen des Handgriffes aufnimmt und mit letzterem über eine lösbare Verriegelungseinrichtung gekuppelt ist, wobei über elektrische Kupplungen eine elektrisch leitende Verbindung von einer Düse am freien Ende des Staubsaugersaugrohres, über das Staubsaugersaugrohr, den Adapter, den Handgriff und einem flexiblen Saugschlauch zur Stromversorgung des Staubsaugers besteht.The invention relates to a vacuum cleaner with handle and adapter which receives at one end the end of a vacuum cleaner and at its other end a pipe socket of the handle and the latter is coupled via a releasable locking device, wherein via electrical couplings an electrically conductive connection from a nozzle at the free end of the vacuum cleaner suction pipe, over the vacuum cleaner suction pipe, the adapter, the handle and a flexible suction hose for the power supply of the vacuum cleaner.
Ein derartiger Staubsauger ist seit langem in den Vereinigten Staaten in Gebrauch und daher offenkundig benutzt, kann jedoch druckschriftlich derzeit nicht belegt werden. Bei diesem Staubsauger gemäß dem Stand der Technik besteht der Adapter aus einer den unteren Teil des Endbereiches des Staubsaugersaugrohres formschlüssig untergreifenden Kunststoffleiste, die mit einer im Querschnitt U-förmigen Verlängerung über das Ende des Staubsaugersaugrohres hinausragt und im Stegbereich des U-förmigen Querschnittes mit einem Stecker zur Kupplung mit dem Buchsenteil am Handgriff versehen ist. Der Stecker ist mit einer gewendelten, elektrischen Leitung verbunden, die sich entlang dem Staubsaugersaugrohr erstreckt. Der Adapter ist mit mehreren Nieten unlösbar am Endbereich des Staubsaugersaugrohres befestigt. Wird dieser Adapter Biege- oder Stoßkräften ausgesetzt, z. B. bei einem schlagartigen Aufsetzen auf dem Boden oder bei unsachgemäßer Kupplung oder Lagerung des Staubsaugersaugrohres, kann der Adapter abbrechen, mit der Folge, daß dann nicht nur der Adapter, sondern das komplette Staubsaugersaugrohr gegen ein neues ausgetauscht werden mussSuch a vacuum cleaner has been in use in the United States for a long time and is therefore obviously used but can not currently be documented in printed form. In this vacuum cleaner according to the prior art, the adapter consists of a lower part of the end portion of the vacuum cleaner suction undercut plastic strip which protrudes with a cross-sectionally U-shaped extension over the end of the vacuum cleaner suction and in the web portion of the U-shaped cross-section with a plug is provided for coupling with the socket part on the handle. The plug is connected to a coiled electrical line extending along the vacuum cleaner suction tube. The adapter is permanently attached to the end of the vacuum cleaner with several rivets. If this adapter exposed to bending or impact forces, z. B. at a abrupt placement on the floor or inappropriate coupling or storage of the vacuum cleaner suction tube, the adapter can break off, with the result that then not only the adapter, but the entire vacuum cleaner suction pipe has to be replaced with a new one

Hier setzt nun die Erfindung ein. Dieser liegt die Aufgabe zugrunde, einen Staubsauger der eingangs genannten Gattung zu schaffen, der nicht nur einen robusten Adapter aufweist, sondern auch bei dessen Zerstörung kein neues Staubsaugersaugrohr erfordert.This is where the invention begins. This is the object of the invention to provide a vacuum cleaner of the type mentioned, which not only has a robust adapter, but also in its destruction does not require a new vacuum cleaner.
Diese Aufgabe wird in Verbindung mit dem eingangs genannten Gattungsbegriff erfindungsgemäß dadurch gelöst, daß der Adapter von mindestens zwei Schalen gebildet ist, die über ein zur Längsachse des Staubsaugersaugrohres parallel verlaufendes Filmscharnier schwenkbeweglich verbunden sind und an ihren freien Endbereichen über eine Schraubverbindung in ihrer Montageendlage lösbar gegen den zugekehrten Endbereich des Staubsaugersaugrohres verspannt sind. Mit diesem Staubsauger wird erstmalig ein vom Staubsaugersaugrohr lösbarer Adapter geschaffen, der bei Beschädigungen rasch gegen einen neuen ausgetauscht werden kann.This object is achieved in conjunction with the generic term mentioned in the present invention that the adapter is formed by at least two shells, which are pivotally connected via a longitudinal axis of the vacuum cleaner suction parallel film hinge and at their free end portions via a screw in its final assembly position against the facing end of the Vacuum cleaner suction tube are braced. With this vacuum cleaner for the first time a detachable from the vacuum cleaner suction adapter is created, which can be quickly replaced in case of damage to a new one.
Darüber hinaus umgreift er mit seinem einen Ende den ihm zugekehrten Bereich des Staubsaugersaugrohres vollständig und nicht wie beim Stand der Technik nur an einem geringen Umfangsbereich und wird bei der Endmontage verwackelungsfrei mit diesem Endbereich des Staubsaugersaugrohres über eine Schraubverbindung verspannt und damit kraft- und formschlüssig mit dem Staubsaugersaugrohr verbunden. Durch seine vollständige und damit schützende Umschlingung des Endbereiches des Staubsaugersaugrohres erhält der gesamte Staubsauger nicht nur eine robuste, sondern auch eine optisch gefällige Form.In addition, it surrounds with its one end to him facing the area of the vacuum cleaner suction completely and not as in the prior art only at a small peripheral area and is braked during final assembly shake-free with this end of the vacuum cleaner via a screw and thus positively and positively with the Vacuum cleaner suction pipe connected. Due to its complete and therefore protective looping around the end region of the vacuum cleaner suction tube, the entire vacuum cleaner not only has a robust but also a visually pleasing shape.
Um ein Verdrehen des Staubsaugersaugrohres relativ zum Handgriff zu unterbinden, ist der Adapter außer mit seiner Verspannung gegen das Rohrende des Staubsaugersaugrohres mit einem Verdrehungsschutz versehen. Dieser Verdrehungsschutz besteht vorteilhaft aus einer Ausnehmung am Ende des dem Adapter zugewandten Staubsaugersaugrohres und aus einem darin eingreifenden Nocken des Adapters.In order to prevent twisting of the vacuum cleaner suction relative to the handle, the adapter is provided except with its tension against the pipe end of the vacuum cleaner with a rotation protection. This twist protection advantageously consists of a recess at the end of the vacuum cleaner suction pipe facing the adapter and a cam of the adapter engaging therein.
Ein Abziehen des Adapters vom Endbereich des Staubsaugersaugrohres wird sowohl durch diesen Nocken als auch durch die kraftschlüssige Verspannung und ein Abziehen des Adapters vom Rohrstutzen des Handgriffes durch die Verriegelungseinrichtung unterbunden.A removal of the adapter from the end of the vacuum cleaner suction tube is prevented both by this cam and by the non-positive tension and a removal of the adapter from the pipe socket of the handle by the locking device.
Nach einer besonders vorteilhaften Weiterbildung der Erfindung besteht der Adapter insgesamt aus drei Schalen, die über zwei zur Längsachse des Staubsaugersaugrohres parallel verlaufende Filmscharniere miteinander verbunden sind. Davon sind die beiden äußeren Schalen etwa gleich und die mittlere Schale streifenförmig ausgebildet. Sämtliche Schalen weisen an ihren Innenseiten die Form von Teilkreissegmenten auf, die in ihrer Montageendlage den von ihnen aufgenommenen Endbereich des Staubsaugersaugrohres sowie den Rohrstutzen des Handgriffes kreisförmig umgreifen. Dadurch wird auch dieser Endbereich des Staubsaugersaugrohres vom Adapter gegen Verformungen oder sonstige Deformationen geschützt.According to a particularly advantageous embodiment of the invention, the adapter consists of a total of three shells, which are connected to each other via two parallel to the longitudinal axis of the vacuum cleaner suction film hinges. Of these, the two outer shells are about the same and the middle shell is strip-shaped. All shells have on their inner sides the shape of pitch circle segments, which surround in their Montageendlage received by them end portion of the vacuum cleaner suction pipe and the pipe socket of the handle circular. As a result, this end region of the vacuum cleaner suction pipe is protected by the adapter against deformation or other deformations.
Ferner schmiegt sich der Adapter durch den kreisförmigen Umgriff des Endbereiches sowohl der Form des Staubsaugersaugrohres als auch der des Handgriffes an mit der Folge, daß nicht nur eine robuste, lösbare Kopplung, sondern auch eine optisch ansprechende Verbindung zwischen Handgriff und Staubsaugersaugrohr geschaffen wird.Further, the adapter nestles by the circular wrap of the end portion of both the shape of the vacuum cleaner suction pipe and the handle with the result that not only a robust, releasable coupling, but also a visually appealing connection between the handle and vacuum cleaner suction tube is created.
Vorteilhaft sind bei der dreiteiligen Schalenform des Adapters die beiden äußeren Schalen an ihrem dem Handgriff zugekehrten Ende mit je einer vorspringenden, im Querschnitt L-förmigen Leiste versehen, die in ihrer Montageendlage eine im Querschnitt U-förmige Aufnahme für den im Querschnitt ebenfalls U-förmigen sowie geometrisch ähnlich ausgebildeten Teil des Handgriffes an seiner Unterseite bilden und diesen untergreifen. Dabei dient die U-förmige Aufnahme nicht nur einer Erleichterung der Kopplung zwischen Adapter und Rohrstutzen mittels der Verriegelungseinrichtung, sondern auch zur exakten und verdrehungsfreien Führung von dem Steckerteil in das Buchsenteil einer elektrisch leitenden Verbindung, auf die noch nachfolgend eingegangen werden wird.Advantageously, in the three-part shell shape of the adapter, the two outer shells are provided at their end facing the handle with a projecting, in cross-section L-shaped bar in their Montageendlage a cross-sectionally U-shaped receptacle for the cross-section also U-shaped and form geometrically similar part of the handle on its underside and engage under this. The U-shaped receptacle serves not only to facilitate the coupling between the adapter and pipe socket by means of the locking device, but also for the exact and torsion-free guidance of the Plug part in the socket part of an electrically conductive connection, which will be discussed below.
Der mittlere Teil der Schale ist vorteilhaft in seinem Mittenbereich mit einer blattfederartig angeformten Taste zum Niederdrücken der Verriegelungseinrichtung am Rohrstutzen versehen. Beim Stand der Technik war diese Taste dem Adapter gegenüberliegend am Außenumfang des Staubsaugersaugrohres angeordnet und erforderte somit eine zusätzliche Befestigung. Dadurch bleibt das Staubsaugersaugrohr ohne Nietverbindung glatt und paßt sich strömungstechnisch und optisch günstig dem Gesamteindruck an.The middle part of the shell is advantageously provided in its central region with a leaf spring-like molded button for depressing the locking device on the pipe socket. In the prior art, this button was located opposite the adapter on the outer circumference of the vacuum cleaner suction tube and thus required additional attachment. As a result, the vacuum cleaner suction remains smooth without riveting and fits fluidly and optically favorable to the overall impression.
Zur Erzielung einer großen Steifigkeit und Schlagfestigkeit, trotz Materialersparnis bei der Gestaltung der Wanddicken, sind die Schalen an ihrer Innenseite mit Versteifungsrippen versehen. Diese Versteifungsrippen sind an ihren freien Enden teilkreisförmig ausgebildet, um sich dem Außendurchmesser des Endbereiches des Staubsaugersaugrohres durch Verspannung entsprechend federnd günstig anpassen zu können.To achieve a high stiffness and impact resistance, despite material savings in the design of the wall thicknesses, the shells are provided on their inside with stiffening ribs. These stiffening ribs are part-circular in shape at their free ends, in order to be able to adapt to the outer diameter of the end region of the vacuum cleaner suction tube in a correspondingly resilient manner by means of bracing.
Vorteilhaft ist an beiden Endbereichen einer Schale je eine Durchgrifföffnung für eine Spannschraube und auf der Innenseite der gegenüberliegenden Schale dazu korrespondierende Sackbohrungen zur Aufnahme der Spannschrauben angeordnet. Bei einer dreiteiligen Schale sind die Durchgrifföffnungen für die Spannschrauben und die Aufnahmen der Spannschrauben an den Außenschalen angeordnet, nicht jedoch an der mittleren Schale.It is advantageous at both end regions of a shell depending on a through opening for a clamping screw and arranged on the inside of the opposite shell corresponding blind holes for receiving the clamping screws. In a three-piece shell, the through-openings for the clamping screws and the recordings of the clamping screws are arranged on the outer shells, but not on the middle shell.
Für einen gattungsgemäßen Staubsauger, der an seinem Düsenteil mit einer Bürste oder einer Walze versehen ist, erfordert deren elektrischer Antrieb eine elektrische Verbindungsleitung zur Stromzuführung. Diese Verbindungsleitung wird von der Düse über das Staubsaugersaugrohr, den Handgriff, an dem sich regelmäßig ein entsprechender elektrischer Schalter befindet und über den anschließenden flexiblen Schlauch zur Stromversorgung des Motors zum Antrieb des saugenden Radiallüfters geführt. Zur Schaffung dieser elektrischen Verbindung weisen die Schalen an ihrem dem Handgriff zugekehrten Endbereich eine Ausnehmung zum Einsatz eines elektrischen Steckers für diese elektrisch leitende Verbindung entlang dem Staubsaugersaugrohr auf. Dieser Stecker wird beim Aufschieben des Adapters auf den Rohrstutzen des Handgriffes mit einem am Stirnende des Handgriffes angeordneten elektrischen Buchsenteil gekuppelt. Diese elektrisch leitende Verbindung wird sodann durch den Handgriff und den anschließenden Saugschlauch bis zur vorbeschriebenen Stromversorgung geführt.For a generic vacuum cleaner, which is provided at its nozzle part with a brush or a roller, whose electric drive requires an electrical connection line to the power supply. This connecting line is led from the nozzle via the vacuum cleaner suction tube, the handle, which is regularly a corresponding electrical switch and the subsequent flexible hose to power the motor to drive the sucking radial fan. To create this electrical connection, the shells have at their end facing the handle a recess for the use of an electrical connector for this electrically conductive connection along the vacuum cleaner suction pipe. This plug is coupled when pushing the adapter on the pipe socket of the handle with a arranged at the front end of the handle electrical socket part. This electrically conductive connection is then guided by the handle and the subsequent suction hose to the above-described power supply.
Zur einfachen sowie preiswerten Herstellung sind die Schalen aus Kunststoff, insbesondere aus Polyamid (PA) oder aus Polypropylen (PP) hergestellt. Das Staubsaugersaugrohr kann in an sich bekannter Weise als Teleskoprohr ausgebildet sein.For simple and inexpensive production, the shells are made of plastic, in particular polyamide (PA) or polypropylene (PP). The vacuum cleaner suction can be formed in a conventional manner as a telescopic tube.
