According to the invention, the door hinge is designed as a snap hinge, the housing (1) having an upper hinge pin (11) and a lower hinge pin (12) and the door correspondingly having an upper hinge bore (21) and a lower hinge bore (22) with a lateral opening (23) in the wall of the bore. The upper hinge pin (11) has a circular cross-section (13), the upper hinge bore being designed as a blind hole. The lower hinge pin (12) has a wedge-shaped cross-section, the lateral opening of the lower hinge bore being designed in the form of a wedge. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Handgefahrenmelder mit einem Gehäuse sowie einer Tür gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a manual hazard detector with a housing and a door according to the preamble of claim 1.

Handgefahrenmelder, im allgemeinen als Druckknopfmelder bezeichnet, werden seit langem aus Kunststoff gefertigt und insbesondere als Handfeuermelder verwendet. Dabei werden die Türscharniere am Kunststoffgehäuse je nach Einsatzfall auf vielfältige Art ausgeführt. Die Größe des Gehäuses und der verwendete Kunststoff spielen hierbei eine entscheidende Rolle. Bisher war die Tür des Handfeuermelder-Gehäuses durch zwei Metallscharnierstifte mit dem Gehäuse verbunden. Diese bisherige Ausführungsform hat jedoch den Nachteil, daß für jeden Handfeuermelder zwei zusätzliche Metallscharnierstifte erforderlich sind, und daß die Montage der Türe am Gehäuse umständlich und zeitaufwendig ist.Manual hazard detectors, generally as push button detectors have long been made of plastic and especially used as a manual call point. Here the door hinges on the plastic housing depending on Use case carried out in a variety of ways. The size of the Housing and the plastic used play here a crucial role. So far, the door of the manual call point housing was through two metal hinge pins connected to the housing. This previous embodiment has the disadvantage, however, that for every manual call point two additional metal hinge pins are required and that the assembly of the door on the housing cumbersome and is time consuming.

Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden und das Türscharnier für Handgefahrenmelder weiterzubilden und in besonderer Weise auszugestalten.The object of the invention is to avoid these disadvantages and to further develop the door hinge for manual hazard detectors and to design it in a special way.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of Claim 1 solved.

Das erfindungsgemäße Türscharnier ist als Schnappscharnier ausgebildet, so daß es ohne Scharnierstift auskommt. Das bedeutet, die Tür kann verhältnismäßig einfach im Gehäuse eingesetzt werden. Dazu weist das Gehäuse einen oberen und einen unteren Scharnierbolzen auf und die Tür dazu entsprechend angeordnete obere und untere Scharnierbohrungen, wobei nur die untere Scharnierbohrung eine seitliche Öffnung in der Wandung der Bohrung aufweist. Das hat den Vorteil, daß durch Wegfall der zwei Metallscharnierstifte die Teilekosten vermindert werden und darüberhinaus, daß sich die Montagezeiten verkürzen.The door hinge according to the invention is a snap hinge trained so that it does not require a hinge pin. The means the door can be relatively simple in the housing be used. For this purpose, the housing has an upper and a lower hinge pin and the door accordingly arranged upper and lower hinge holes, only the lower hinge hole has a side opening has in the wall of the bore. That has the advantage, that by eliminating the two metal hinge pins Parts costs are reduced and beyond that shorten assembly times.

In einer besonderen Ausgestaltung der Erfindung weist der obere Scharnierbolzen einen kreisförmigen Querschnitt auf und die obere Scharnierbohrung ist als Sackloch ausgebildet. Der untere Scharnierbolzen weist einen keilförmigen Querschnitt auf und die seitliche Öffnung der Scharnierbohrung ist keilförmig ausgebildet. Beim Einsetzen der Tür im Gehäuse des Handfeuermelders wird die obere Scharnierbohrung an der Tür in den oberen Scharnierbolzen am Gehäuse eingeführt und in Endstellung gebracht. Die untere Scharnierbohrung mit der seitlichen keilförmigen Öffnung wird unter kurzzeitiger Überdehnung der Wandung in den keilförmig verdickten Bolzen eingeschnappt. Die Tür und das Gehäuse sind dann miteinander untrennbar verbunden.In a special embodiment of the invention, the upper hinge pin has a circular cross section and the upper hinge hole is designed as a blind hole. The lower hinge pin has a wedge-shaped Cross section on and the side opening of the hinge hole is wedge-shaped. When inserting the door The upper hinge hole is in the housing of the manual call point on the door in the upper hinge bolts on the housing introduced and brought into the final position. The lower one Hinge hole with the side wedge-shaped opening is under brief stretching of the wall in the Wedge-shaped bolt snapped into place. The door and the housing is then inseparable.

Seitlich einschnappende Scharniere sind aus der US-A-5 146 650 bekannt, Hierbei gibt es keine separate Bohrungen von denen nur eine eine seitliche Öffnung aufweist.Hinges that snap into the side are known from US Pat. No. 5,146,650. There are no separate bores, of which only one has a side opening.

Zweckmäßigerweise kann der obere und der untere Scharnierbolzen an der Stirnseite unter einem bestimmten Winkel, z.B. 45°, angefast sein, was in vorteilhafter Weise ein leichteren Einsetzen gewährleistet.The upper and lower hinge bolts can expediently on the face at a certain angle, e.g. 45 °, beveled, which is advantageous ensures easier insertion.

In vorteilhafter Weise sind die Scharnierbolzen am Gehäuse angespritzt.The hinge bolts are advantageously on the housing molded.

Die Erfindung wird im folgenden anhand der Zeichnung kurz erläutert. The invention is briefly described below with reference to the drawing explained.
