Dusenstockschutzhulle für MontageschaumpistolenNozzle protection cover for assembly foam guns
Montageschaumpistolen üblicher Bauart Fig. 3 bestehen im wesentlichen aus einem Griff mit Abzugshebel, einer Stellschraube,mit der die Schaumaustrittsmenge geregelt werden kann. Einem Adapter zur Aufnahme der Montageschaumdose und einem Düsenstock 3/1 mit Distanzrohr 3/2 an der sich vorne die Schaumaustrittsdüse 3/4 befindet.Assembly foam guns of the usual design (Fig. 3) essentially consist of a handle with a trigger, an adjusting screw with which the amount of foam that comes out can be regulated, an adapter for holding the assembly foam can and a nozzle holder 3/1 with a spacer tube 3/2 on which the foam outlet nozzle 3/4 is located at the front.
Bei Anwendung der Montageschaumpistole setzen sich Pü-Schaumreste an der Düsennase 3/3 und am Distanzrohr 3/2 fest, die sich nur mechanisch entfernen lassen.When using the assembly foam gun, PU foam residues stick to the nozzle nose 3/3 and the spacer tube 3/2 and can only be removed mechanically.
In den Betriebsanleitungen der jeweiligen Hersteller von Pü-Schaumpistolen wird bereits darauf hingewiesen, daß ausgehärtete Schaumreste mit Messer und Stahlbürste vom hochempfindlichen Düsenstock 3/1 zu entfernen sind.The operating instructions of the respective manufacturers of PU foam guns already indicate that hardened foam residues must be removed from the highly sensitive nozzle holder 3/1 using a knife and steel brush.
Düse 3/4 und Distanzrohr 3/2 werden durch die wiederholte, zeitraubende mechanische Reinigung in der Oberfläche immer mehr aufgerauht. Eine Reinigung wird nach jedem Gebrauch immer schwieriger und letztendlich der Düsenstock 3/1 dadurch beschädigt.The surface of nozzle 3/4 and spacer tube 3/2 becomes increasingly rough due to repeated, time-consuming mechanical cleaning. Cleaning becomes increasingly difficult after each use and ultimately the nozzle holder 3/1 is damaged as a result.
Nicht nur die zeitraubende Reinigung verursacht Schaden am Düsenstock 3/1, sondern durch die übliche Anwendung entstehen zusätzlich Schäden durch seitliches Berühren von Mauerwerk-Beton oder Mörtel die ein Abrieb der Düsennase 3/3 verursachen und somit die eigentliche Düse 3/4 beschädigt.Not only does the time-consuming cleaning cause damage to the nozzle holder 3/1, but the usual use also causes damage through lateral contact with masonry concrete or mortar, which causes abrasion of the nozzle nose 3/3 and thus damages the actual nozzle 3/4.
Die Folge ist, daß der hochempfindliche Düsenstock 3/1 Sauerstoff durchläßt und somit Schaum im Distanzrohr 3/2 aushärtet. Die Montagepistole ist nicht mehr einsatzfähig. Bei einigen Fabrikaten muß die Pistole ganz ersetzt werden, bei anderen, z.B. der Bauart "Pageris" mindestens der Düsenstock 3/1 im Herstellerwerk ausgetauscht werden.The result is that the highly sensitive nozzle holder 3/1 lets oxygen through and thus foam hardens in the spacer tube 3/2. The assembly gun is no longer usable. For some makes, the gun must be completely replaced, for others, e.g. the "Pageris" model, at least the nozzle holder 3/1 must be replaced at the manufacturer's factory.

Das Problem wird mit der im Schutzanspruch 1 aufgeführten Düsenschutzhülle 1/1 aus speziellem Kunststoff gelöst. Ein Stoßdämpfungsring 1/2 sichert den Düsenstock 3/1 zusätzlich vor Beschädigungen bei unbeabsichtigter Stoßoder Schlageinwirkung.The problem is solved with the nozzle protection cover 1/1 made of special plastic, as specified in claim 1. A shock absorption ring 1/2 additionally protects the nozzle holder 3/1 from damage in the event of an unintentional impact or shock.
Montageschaumreste, die an der Düsenschutzhülle 1/1 aushärten, können ohne Kraftaufwand mit der Hand abgestreift werden. Ein Verbund zwischen Montageschaum und Schutzhülle wird auf Grund der Materialzusammensetzung unterbunden .Assembly foam residues that harden on the nozzle protective cover 1/1 can be easily removed by hand. A bond between assembly foam and protective cover is prevented due to the material composition. .
Zeitaufwendige und schädigende Reinigung entfällt. Distanzrohr und Düsennase sind vor schädigendem Abrieb geschützt.Time-consuming and damaging cleaning is no longer necessary. The spacer tube and nozzle nose are protected against damaging abrasion.
Die Funktion einer Pü-Schaumpistole ist damit langfristig gesichert.The function of a PU foam gun is thus secured in the long term.
Eine verschlissene Schutzhülle ist leicht,schnell und kostengünstig zu ersetzen.A worn protective cover can be replaced easily, quickly and inexpensively.
In den folgenden Zeichnungen wird die Erfindung schematisch dargestellt.The invention is shown schematically in the following drawings.
Fig. 1 zeigt eine Düsenstockschutzhülle mit Stoßdämpfer auf Distanzrohr aufgeschoben.Fig. 1 shows a nozzle holder protective cover with shock absorber pushed onto a spacer tube.
Fig. 2 zeigt eine stirnseitige Ansicht vom Düsenstock mit aufgeschobener Düsenstockschutzhülle und Stoßdämpfungsring.Fig. 2 shows a front view of the nozzle holder with the nozzle holder protective cover and shock absorption ring pushed on.
Fig. 3 zeigt eine Montageschaumpistole üblicher Bauart.Fig. 3 shows a conventional assembly foam gun.
