Description

Die Erfindung betrifft einen Saugkopf an einem Staubsauger, welcher Saugkopf einen zum zu reinigenden Boden hin offenen, quer zur Bewegungsrichtung des Saugkopfes verlaufenden kanalförmigen Saugmund mit Saugöffnung sowie in Bewegungsrichtung vor und hinter dem Saugmund eine Borstenleiste aufweist, die mit einer Trägerplatte verbunden ist. Ein Saugkopf des beschriebenen Aufbaus ist z.B. aus DE-A 27 53 798 bekannt.The invention relates to a suction head on a vacuum cleaner, which suction head is towards the floor to be cleaned open, transverse to the direction of movement of the suction head channel - shaped suction mouth with suction opening and in Direction of movement in front of and behind the suction mouth Bristle strip, which is connected to a carrier plate is. A suction head of the construction described is e.g. known from DE-A 27 53 798.

Die Borstenleisten unterstützen bei arbeitendem Staubsauger als staublösende Bürsten die Reinigungsarbeit. Sie haben bei der hin- und hergehenden Arbeitsbewegung des Saugkopfes, aber auch aus Kräften, die den Saugkopf auf den zu reinigenden Boden drücken und die von einer Bedienungsperson ausgeübt werden, nicht unbeachtliche Beanspruchung aufzunehmen. Die Borstenleisten können im übrigen als Stützelemente dienen, mit denen der Saugkopf auf dem zu reinigenden Boden abgestützt ist. Als Stützelemente können aber auch Rollen, Gleitelemente und ähnliche Bauteile, zusätzlich zu den Borstenleisten angeordnet sein. Die Borstenleisten sind an der Unterseite des Saugkopfgehäuses unbeweglich angeordnet oder über zusätzliche Bauteile heb- und senkbar. Bei der Ausführungsform mit heb- und senkbaren Borstenleisten werden die Borstenleisten eingefahren, wenn sie die Reinigungsarbeit behindern, was z.B. auf hochflorigen Teppichböden der Fall sein kann. The bristle strips support when the vacuum cleaner is working cleaning work as dust-removing brushes. They have during the back and forth working movement of the suction head, but also from forces that move the suction head towards the Press cleaning floor and that of an operator are exercised, not insignificant stress to record. The bristle strips can also be used as Support elements are used with which the suction head on the cleaning floor is supported. Can be used as support elements but also rollers, sliding elements and similar components, in addition be arranged to the bristle strips. The Bristle strips are on the underside of the suction head housing arranged immovably or lifting and using additional components lowerable. In the embodiment with lifting and lowering Bristle strips, the bristle strips are retracted when they hinder the cleaning work, e.g. on deep-pile Carpets may be the case.

Die Borstenleisten weisen in der Praxis häufig eine U-förmig geformte Blechleiste als Borstenleistenrücken auf, in welche die Borsten eingeführt und in der sie festgeklemmt sind. Das ist fertigungsmäßig aufwendig. In einem kontinuierlichen Prozeß werden die Borsten auf ein Blechband, welches beispielsweise 15 mm breit ist, mit einer Länge, die gut der doppelten Höhe der Borsten in der fertigen Borstenleiste entspricht, quer zur Bandrichtung in definierter, gleichmäßiger Schichtdicke aufgelegt. Darüber wird ein Stahldraht, mittig zum Stahlband gelegt. Das Blechband mit den aufgelegten Borsten wird U-förmig um den Stahldraht mit den unterlegten Borsten herumgebogen und zusammengepreßt. Der Stahldraht als Seele verhindert das Herausfallen der U-förmig gebogenen und vom Blechband eingeklemmten Borsten. Anschließend werden die überstehenden Borsten auf Fertighöhe geschoren. Gegebenenfalls werden Aussparungen eingestanzt und der Borstenstreifen wird auf Fertigungslängen abgelängt. Die beschriebene Ausführungsform hält man aus Festigkeitsgründen und Gründen der Gestaltfestigkeit für erforderlich, da beim Arbeiten mit dem Staubsauger erhebliche Beanspruchungen aufzunehmen sind.The bristle strips often have one in practice U-shaped sheet metal strip as bristle strip back, into which the bristles are inserted and in which they are clamped are. This is complex in terms of production. In one continuous process, the bristles are placed on a metal strip, which is, for example, 15 mm wide, with a Length well twice the height of the bristles in the finished Corresponds to bristle strip, transverse to the band direction in defined, uniform layer thickness. About that a steel wire is placed in the middle of the steel strip. The Sheet metal tape with the bristles placed on it is U-shaped around the Steel wire bent over with the bristles underneath and compressed. The steel wire as a soul prevents that Fall out of the U-shaped bent and clamped by the metal strip Bristles. Then the protruding ones Bristles sheared to finished height. If necessary Cutouts are punched in and the bristle strip is opened Production lengths cut to length. The described embodiment one keeps for reasons of strength and reasons of Dimensional stability required for when working with the vacuum cleaner to absorb significant stress are.

Grundsätzlich ist es auch bekannt, Borstenrücken von Bürsten aus thermoplastischem Kunststoff zu fertigen, in den Borstenbüschel eingesetzt sind. Insoweit wird z.B. auf übliche Zahnbürsten verwiesen.Basically, it is also known to have bristle backs Manufacture brushes from thermoplastic, in the tufts of bristles are inserted. In this respect, e.g. on usual toothbrushes referenced.

Aus US-A-2 411 488 ist ein Saugkopf mit einer rotierenden Bürstenwalze bekannt. Die Bürstenwalze ist mit Borstenelementen bestückt, die aus einer flexiblen Gummileiste und in die Gummileiste eingesetzten Borstenbüscheln bestehen. Die Gummileisten sind in spiralförmige Nuten der Bürstenwalze einsetzbar. Zur Entwicklung von mit Borstenleisten bestückten Trägerplatten des eingangs beschriebenen Aufbaus und der eingangs beschriebenen Zweckbestimmung haben diese Maßnahmen nichts beigetragen.From US-A-2 411 488 is a suction head with a rotating one Brush roller known. The brush roller is with bristle elements equipped with a flexible rubber strip and tufts of bristles inserted into the rubber strip. The rubber strips are in spiral grooves of the brush roller applicable. For the development of with bristle strips equipped carrier plates of the construction described above and the intended purpose described at the beginning have this Measures contributed nothing.

Der Erfindung liegt das technische Problem zugrunde, einen Saugkopf des eingangs beschriebenen Aufbaus mit Borstenleisten auszurüsten, die einfach und wohlgeformt in einer industriellen Serienfertigung hergestellt werden können, leicht montiert werden können und alle aufzunehmenden Beanspruchungen unschwer und mit hoher Standzeit und Gestaltfestigkeit aufnehmen.The invention is based on the technical problem, one Suction head of the construction described at the beginning with bristle strips equip that simple and shapely in one industrial mass production can be produced can be easily assembled and all loads to be absorbed easy and with a long service life and shape stability record, tape.

Die Aufgabe wird bei einem Saugkopf des eingangs beschriebenen Aufbaus erfindungsgemäß dadurch gelöst,

  • daß die Borsten der Borstenleisten in einen aus thermoplastischem Kunststoff geformten Borstenleistenrücken eingebettet sind,
  • daß die Borstenleistenrücken als Versteifungsrandelemente für die aus thermoplastischem Kunststoff geformte Trägerplatte ausgebildet sowie mit dieser verbunden sind und
  • daß die Höhe der Borstenleistenrücken in Richtung der Borsten groß ist im Verhältnis zur Dicke der Trägerplatte,
    • wobei die Borstenleistenrücken die Trägerplatte gegen beanspruchungsbedingte Verformungen aus der Plattenebene heraus und die Trägerplatte die Borstenrücken gegen beanspruchungsbedingte Verformungen in Bewegungsrichtung des Saugkopfes aussteifen. Die Borstenleisten bestehen aus einer durchgehenden Reihe aus dicht an dicht angeordneten Borsten aus thermoplastischem Kunststoff, deren rückwärtiges Ende in einen ebenfalls aus thermoplastischem Kunststoff bestehenden Strang, welcher den Borstenleistenrücken bildet, eingebettet ist. Die Borstenleisten sind im Wege der kontinuierlichen Extrusion herstellbar, wobei der Borstenleistenrücken aus aufgeschmolzenem Borstenmaterial bestehen kann oder aus Material, z.B. Recyclat, besteht, welches während der Extrusion beigefüttert wird. Die Verbindung der Borstenleistenrücken mit der Trägerplatte kann auf verschiedene Weise erfolgen, solange die im folgenden erläuterten Effekte und Wechselwirkungen gewährleistet sind. Vorzugsweise ist die Verbindung eine stoffschlüssige Verbindung. Die Gestaltung der Borstenleistenrücken ist weitgehend beliebig; sie kann der Art der Verbindung angepaßt sein.The object is achieved according to the invention in a suction head of the construction described at the outset by
  • that the bristles of the bristle strips are embedded in a bristle strip back molded from thermoplastic,
  • that the bristle backs are formed as stiffening edge elements for the carrier plate molded from thermoplastic and are connected to it and
  • that the height of the bristle bar back in the direction of the bristles is large in relation to the thickness of the carrier plate,
    • wherein the bristle bar backs brace the carrier plate against stress-related deformations from the plane of the plate and the carrier plate stiffen the bristle backs against stress-related deformations in the direction of movement of the suction head. The bristle strips consist of a continuous row of thermoplastic bristles arranged close together, the rear end of which is embedded in a strand which is also made of thermoplastic and forms the back of the bristle strip. The bristle strips can be produced by continuous extrusion, the back of the bristle strip being made from melted bristle material or from material, for example recycled material, which is fed in during the extrusion. The bristle bar backs can be connected to the carrier plate in various ways, as long as the effects and interactions explained below are ensured. The connection is preferably a material connection. The design of the bristle bar back is largely arbitrary; it can be adapted to the type of connection.

    Die Erfindung geht von der Erkenntnis aus, daß bei den Borstenleisten eines Saugkopfes der Borstenleistenrücken gleichsam als aussteifendes Rückgrad an einer Trägerplatte dienen kann und diese Funktion voll erfüllen kann, wenn die Trägerplatte wie angegeben gestaltet ist und die Borstenleistenrücken stoffschlüssig mit der Trägerplatte verbunden sind, und zwar derart, daß die Borstenleistenrücken die Trägerplatte gegen beanspruchungsbedingte Verformungen aus der Plattenebene heraus und die Trägerplatte die Borstenleistenrücken gegen beanspruchungsbedingte Verformungen in Bewegungsrichtung des Saugkopfes aussteifen. Insoweit arbeitet die Erfindung mit einer besonderen Gestaltung und Vereinigung der Borstenleistenrücken und der Trägerplatte, die darüber hinaus leicht montierbar ist und in der die Borstenleistenrücken einerseits und die Trägerplatte andererseits vorteilhaft wechselwirken. Die Borstenleistenrücken bilden bei beanspruchungsbedingten Verformungen aus der Plattenebene heraus gleichsam aussteifende Randglieder, wie sie im Baugewerbe bei der sogenannten Schalenstatik eingesetzt werden, während andererseits das Flächenträgheitsmoment der Trägerplatte aussteifend auf die Borstenleisten wirkt, die in Bewegungsrichtung des Saugkopfes Beanspruchungen aufzunehmen haben. Im Ergebnis behalten die Borsten der beschriebenen Borstenleisten beim arbeitenden und bewegten Saugkopf ihre Orientierung, die besonders reinigungswirksam eingerichtet werden kann, gleichzeitig werden die Borsten im Borstenleistenrücken sicher und mit langer Standzeit gehalten. In Bewegungsrichtung des Saugkopfes sind an der Trägerplatte abschließende oder aussteifende Leisten und sonstige Ausformungen nicht erforderlich, was die Herstellung im Wege des Strangpressens ermöglicht. Nach bevorzugter Ausführungsform der Erfindung bestehen die Borstenleistenrücken und die Trägerplatten aus dem gleichen thermoplastischen Kunststoff.The invention is based on the knowledge that the Bristle strips of a suction head of the bristle strip back as a stiffening backbone on a support plate can serve and can fully fulfill this function if the Carrier plate is designed as indicated and the bristle strip back cohesively connected to the carrier plate are, such that the bristle backs the Support plate against deformations caused by stress the plate level and the backing plate the bristle back against stress-related deformations in Stiffen the direction of movement of the suction head. So far the invention works with a special design and Union of the bristle bar back and the carrier plate, which is also easy to assemble and in which the Bristle strip back on the one hand and the carrier plate on the other hand interact favorably. The bristle backs train in the case of deformations caused by stress out of the plate level, stiffening as it were, as in the construction industry with the so-called shell statics are used, while on the other hand the area moment of inertia the support plate stiffening on the bristle strips acts in the direction of movement of the suction head Have to absorb stresses. As a result, they keep Bristles of the bristle strips described when working and moved the suction head its orientation, the special cleaning can be set up at the same time the bristles in the back of the bristle strip become safe and with held for a long time. In the direction of movement of the suction head are final or stiffening on the carrier plate Moldings and other shapes are not required, which enables production by extrusion. According to a preferred embodiment of the invention Bristle back and the backing plates from the same thermoplastic.

    Im einzelnen bestehen im Rahmen der Erfindung mehrere Möglichkeiten der weiteren Ausbildung und Gestaltung. So können die Borstenleistenrücken in ausgeformte Randnuten der Trägerplatte eingesetzt und mit dem Werkstoff der Randnuten stoffschlüssig verbunden sein. Man kann aber auch die Borstenleistenrücken an die Trägerplatte anformen und gleichzeitig auch die Borsten in den Borstenleistenrücken durch Einspritzen befestigen. Bei den beschriebenen Maßnahmen kann im Wege des Spritzgießens, aber auch des Strangpressens, gearbeitet werden. Die Trägerplatten mit den angeformten Borstenleisten können als langgestreckte Produkte durch Extrudieren hergestellt werden. Beim Extrudieren können zugleich auch die Borsten in das thermoplastifizierte Material der Trägerplatte eingebracht werden. Nach bevorzugter Ausführungsform der Erfindung sind die Borstenleistenrücken und die Trägerplatte winkelsteif miteinander verbunden, wozu auch im Bereich der Winkel das Flächenträgheitsmoment erhöhende Ausformungen vorgesehen sein können.There are several in the scope of the invention Opportunities for further training and design. So the back of the bristle strip can be formed into shaped edge grooves the carrier plate and with the material of the edge grooves be cohesively connected. But you can also do that Shape the bristle strip back onto the carrier plate and at the same time the bristles in the back of the bristle strip fasten by injection. With the measures described can by injection molding, but also of Extrusion. The carrier plates with The molded bristle strips can be elongated Products are made by extrusion. When extruding can also the bristles in the thermoplastic Material of the support plate are introduced. According to a preferred embodiment of the invention Back of the bristle strip and the carrier plate are angularly rigid with one another connected, which also in the area of angles Formations increasing the moment of inertia are provided could be.
