Description

Elektrogerätewerk Suhl Backraumleu da te, especially for gas and electric stoves

The invention relates to an oven light, in particular for gas and electric stoves with a support for fastening d the incandescent lamp protruding through an opening into the baking chamber on the baking chamber wall and one of the opening on the baking chamber side tightly covering dome, which is attached to the baking chamber wall by twisting the dome socket in a wedge-shaped recess «

There are baking chamber lights are known in which the bulb socket-shaped U-by a Xragbügel is worn, the side webs engage the Sragwandloch superior with mutual m open-edged cuts resiliently wall hole in cutouts of Hrag-, while for fixing the Kalottenfassung, NaOH kind of bayonet catch, in the the (Eragwandloeh protruding free bathing of the side webs inclined slits "are incorporated into which corresponding inclined webs, which are connected to the dome bevel, engage."

the dome mount on the free find of the side bars of the mounting bracket · With these, the reflector disc has a slightly conically tapered collar, the circumference of which is two carries diametrically opposed inclined ribs. These ribs protrude beyond the diameter of the wall hole and are inserted in the recesses of the support wall hole in which the web ends are fixed under the baking tray » By turning the dome socket, the higher located file of the two inclined ribs grips under the Edge area of the supporting wall hole, whereby the spherical socket is tightened «

These known oven lights have the disadvantage that, due to the chosen design principles, for attachment there are very short clamping wedges on the free find of the side bars or on the collar Manufacturing and Saaillier tolerances can only be imperfect be compensated · Only with a relatively large slope of the clamping wedge is sufficient tightening allows · Furthermore, the unintentional loosening the Kai ott enfusion and thus the lifting of the seal to the oven very easily possible

When the spherical cap is removed, the U-shaped mounting brackets are Very easy to push out of its springy holder due to carelessness and fall between the oven and the rear wall. SJLn appropriate service effort is necessary in order to repair this damage · In addition, diametrically arranged ones tend to be Clamping wedges for tilting, which means that there is no more tight and tight

Seat of the spherical socket is guaranteed

There are therefore the baking chamber lighting become known in which the two _a m periphery of the collar diametrically opposite ribs have been long carried out as previously · Here, the two recesses were kept in Xragwandloch verhältnismäBig flat so that when inserted! Teagbügel, d ie bending edges of its middle webs in Xragwmdlooh protrude · The collar is dimensioned here so that it fits between the bending edges of the central webs and, when turning the dome mount, grips with its ribs under the bending edges of the central webs To be so big This eliminates the disadvantages of these oven lights caused by the steep incline of the ribs to the Xragwandloch can disengage towards the middle Finally, the production of a collar with long locking ribs is material and time-consuming and therefore relatively expensive

The invention aims to create a baking light with transport, vibration-proof and tight seat in the supporting wall yoke of the baking chamber, which occurred to a reasonable extent Compensates for manufacturing tolerances, which ultimately ensures a secure fit of the U-shaped mounting bracket in the fastening points of the baking wall when the cap holder is removed

guaranteed The invention is based on the tasks to design the asur attachment of the oven light on the oven wall required connecting elements so that for Attachment of the spherical socket a sufficient angle of rotation and to fix the Eragbügel on the Baokrauawand a suitable siding is available

According to the invention, the support plane of the spherical mount is on the baking chamber wall protruding radially obliquely outwardly angled holding hooks guided in counter to the direction of rotation of the fastening of the Kalottenfaesung spirally rising recesses, these recesses in one of the Fastening relative to each other rerdrehbaren parts are arranged, while the retaining hook on the other of these Ropes are attached

In one embodiment according to the invention, retaining hooks are angled in a trigonal arrangement at the same distance from one another from the circular opening of the calotte mount, which protrude obliquely through the opening of the baking chamber wall and are arranged in the manner of a three-flight Archimedean spiral in the opening of the baking chamber wall, against the direction of rotation of the mounting of the Kar lottenfaesung spirally rising tension leads sindtr

Finally, it is "a feature of the invention that the

Incandescent lamp protruding through an opening in the baking chamber is attached to a U-shaped bracket that is known to ßioh, one leg with two oppositely angled narrow webs and one leg with one behind has wider web angled on the outside, the webs trigonal recesses arranged around the opening of the baking chamber wall reach through in the baking chamber wall, in such a way that the two narrow webs of one leg in the corresponding Recesses in the baking chamber wall rest on contact surfaces that are parallel to the contact surface of the opposite one Recess on which the wider web of the other leg comes to rest due to its pretension, after he has reached through a recess in the sideways over-arched state, which serves with his definition Recess and is offset inward from it ''

The particular advantage of the invention is that a simple connection between the dome mount and the baking chamber wall has been created, which enables self-healing and sealing that meet all requirements with a large angle of rotation guaranteed

The invention is to be explained in more detail below using two exemplary embodiments "n" In the accompanying drawing "own"
