Abstract

The face shield has a transparent visor (8) enclosed by an inner frame part (7). The frame (2) and inner frame part are injection-moulded in one piece. The frame, inner frame part and grille are injection moulded in one piece from plastic. The visor is replaceably fixed. The inside of the visor has an anti-condensation coating. <IMAGE>

Description

Die Erfindung richtet sich auf eine Schutzeinrichtung für Waldarbeiter od.dgl. umfassend einen vor dem Gesicht des Benutzers anbringbaren Rahmen, wobei die Rahmeninnenseite wenigstens teilweise von einem einen Durchblick ermöglichenden Gitter abgedeckt ist.The invention is directed to a protective device for forest workers or the like. comprising a frame which can be attached in front of the face of the user, the inside of the frame being at least partially covered by a grille which enables a view through.

Derartige Schutzeinrichtungen sollen verhindern, daß das Gesicht des Arbeiters verletzt wird, wenn im Gesichtsbereich neben kleineren Partikeln auch größere bzw. großflächigere Gegenstände auftreffen, wie z.B. Zweige und Äste, Sägespäne und dgl.Such protective devices are intended to prevent the face of the worker from being injured if, in addition to smaller particles, larger or larger objects such as e.g. Twigs and branches, sawdust and the like

Ein Nachteil bekannter derartiger Schutzeinrichtungen besteht darin, daß bei der Auswahl der Maschenweite des Gitters Kompromisse insoweit eingegangen werden müssen, als ein relativ weitmaschiges Gitter zwar eine relativ ungehinderte Sicht ermöglicht, dafür aber den Durchtritt kleinerer Partikel ermöglicht, wohingegen ein engmaschiges Gitter zwar weitgehenden Schutz gegen auftreffende Teilchen ermöglicht, jedoch die Sicht deutlich beeinträchtigt.A disadvantage of known protective devices of this type is that compromises have to be made in the selection of the mesh size of the grating insofar as a relatively wide-meshed grille does allow a relatively unobstructed view, but allows small particles to pass through, whereas a close-meshed grille does provide extensive protection against Impinging particles allows, but the visibility is significantly impaired.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Schutzeinrichtung der eingangs genannten Art so auszugestalten, daß unter Beibehaltung einer optimalen Schutzwirkung die Sicht deutlich verbessert wird.Proceeding from this, the object of the invention is to design a protective device of the type mentioned at the outset in such a way that the visibility is significantly improved while maintaining an optimal protective effect.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in dem Bereich vor den Augen das Gitter durch eine transparente Sichtscheibe ersetzt ist.This object is achieved in that the grid is replaced by a transparent lens in the area in front of the eyes.

Dementsprechend wird eine stabile und an sich bewährte Konstruktion beibehalten, wobei die für die Sicht nicht relevanten Außenbereiche in herkömmlicher Weise durch ein Gitter abgedeckt sind, wohingegen andererseits durch die transparente Sichtscheibe eine optimale Sicht ermöglicht wird, so daß Ermüdungserscheinungen auch bei längerem Arbeiten mit heruntergelassenem Visier vermieden werden, weil der Arbeiter in gewohnter Weise mit den Augen fokussieren kann, ohne daß er, wie dies bei Gittern erforderlich ist, bewußt eine "Ferneinstellung" vornehmen muß, um eine Sehbeeinträchtigung zu vermeiden.Accordingly, a stable and proven construction is retained, with the outside areas not relevant for the view being covered in a conventional manner by a grille, whereas on the other hand the transparent lens enables an optimal view, so that fatigue even when working with the visor down for a longer period of time can be avoided because the worker can focus with the eyes in the usual way, without having to consciously make a "remote adjustment", as is required with grids, in order to avoid visual impairment.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, daß die Sichtscheibe von einem inneren Rahmenteil umgeben ist. Dementsprechend ist eine zuverlässige Positionierung und Formgebung der Sichtscheibe gewährleistet, wobei insoweit auf Techniken zurückgegriffen werden kann, wie sie von der Konstruktion von Schutzbrillen her bekannt sind.In a further embodiment of the invention it can be provided that the viewing window is surrounded by an inner frame part. Accordingly, a reliable positioning and shaping of the lens is ensured, whereby techniques can be used that are known from the construction of safety glasses.

Günstigerweise ist vorgesehen, daß der Rahmen und das innere Rahmenteil einstückig gespritzt sind, dabei bietet es sich insbesondere mit Vorteil an, daß man sowohl Rahmen, inneres Rahmenteil als auch das Gitter einstückig aus Kunststoff spritzt.It is advantageously provided that the frame and the inner frame part are injection-molded in one piece, and it is particularly advantageous that both the frame, the inner frame part and the grid are injection-molded in one piece from plastic.

Die Sichtscheibe kann austauschbar an dem inneren Rahmenteil befestigt sein, so daß sie nach längerem Gebrauch, d.h. wenn die Transparenz durch Kratzer od.dgl. beeinträchtigt ist, erneuert werden kann.The lens can be interchangeably attached to the inner frame member so that after prolonged use, i.e. if the transparency due to scratches or the like. is impaired, can be renewed.

Da Arbeiter bei der Arbeit naturgemäß schwitzen, ist mit Vorteil weiterhin vorgesehen, daß die Innenseite der Sichtscheibe mit einer Antibeschlagbeschichtung versehen ist.Since workers sweat naturally at work, it is also advantageously provided that the inside of the lens is provided with an anti-fog coating.

Nachfolgend wird die Erfindung anhand einer bevorzugten Ausführungsform in Verbindung mit der Zeichnung näher erläutert. Dabei zeigen

Fig. 1
eine schematische perspektivische Ansicht einer Schutzvorrichtung der in Betracht stehenden Art bei Befestigung an einem Schutzhelm und
Fig. 2
eine Aufsicht auf die Vorderseite des Rahmens im nicht-gewölbten Zustand.
The invention is explained in more detail below on the basis of a preferred embodiment in conjunction with the drawing. Show
Fig. 1
is a schematic perspective view of a protective device of the type in question when attached to a hard hat and
Fig. 2
a top view of the front of the frame in the non-curved state.

In Fig. 1 ist ein Schutzhelm 1 dargestellt, an welchem eine erfindungsgemäße Schutzeinrichtung 2 über eine Schwenk- und Arretiereinrichtung 3 schwenkbar befestigt ist.In Fig. 1, a protective helmet 1 is shown, on which a protective device 2 according to the invention is pivotally attached via a pivoting and locking device 3.

Die Schutzeinrichtung 2 weist einen äußeren Rahmen 4 mit seitlich nach hinten gerichteten Ansätzen 5 auf, welche mit der Schwenk- und Arretiereinrichtung 3 verbunden sind.The protective device 2 has an outer frame 4 with laterally rearwardly directed lugs 5, which are connected to the pivoting and locking device 3.

Die Innenseite des Rahmens ist mit einem Netz 6 versehen.The inside of the frame is provided with a net 6.

Aus Fig. 2 ist erkennbar, daß in den äußeren Rahmen 2 ein inneres Rahmenteil 7 eingesetzt ist, welches seinerseits eine Sichtscheibe 8 umgibt, so daß im Bereich der Augen und unterhalb derselben aufgrund der Sichtscheibe 8 eine freie Sicht für den Benutzer gewährleistet ist.From Fig. 2 it can be seen that in the outer frame 2, an inner frame part 7 is inserted, which in turn surrounds a lens 8, so that a clear view for the user is guaranteed in the area of the eyes and below it due to the lens 8.
