OBJECT OF THE INVENTION
[0001] The following invention, according to the above mentioned heading, is an improvement
in the support plate of the cooking ceramic glass, being that support plate a decorative
element at the same time and made of stainless or enameled steel, its configuration
being obtained by hammering from the base plate.
[0002] The improvements are based on a punching in the corners of the support frame of the
ceramic glass, without causing a total release of material, thus avoiding the so expensive
ceramic glass can be broken during the operation previous to this installation, which
would make it useless and not viable from the economic point of view.
BACKGROUND OF THE INVENTION
[0003] The ceramic glass to be used in cooking is leant on a frame obtained by hammering
from a base plate, being a decorative element at the same time, in such a way that
if the configuration of the support base of the ceramic glass is made with prominent
angles there can be accumulations of stress in specific points that which cause the
breaking of the base plate, making it useless, so it must be made with slightly prominent
angles.
[0004] This disadvantage worsens in the corners of the support plate, in such a way that
the ceramic glass is made with its rounded the corners in order to avoid its contact
with the support plate, which would cause its breaking. Therefore, it is necessary
to manufacture the ceramic glass with its rounded corners, and this increases its
cost highly in the manufacturing process.
[0005] In case of breaking of the ceramic glass, so minimum though, makes it useless with
minimum reliabilty guarranties, since its performance is completely unforeseeable.
DESCRIPTION OF THE INVENTION
[0006] In this memory, we describe some improvements performed in the support plate of the
ceramic glass to be used in cooking, based on a punch in each corner of the perimeter
support frame of the ceramic glass, with no material release.
[0007] Therefore, the punching is made in the corners of the perimeter support frame of
the ceramic glass, causing the partial release of the area of the corner whose internal
side is under the support level of the ceramic glass, thus avoiding its contact with
the support plate and, at the same time, the drop of material that could accumulate
in inconvenient locations.
[0008] In this way, we can avoid the breakings of the ceramic glass caused during the operation
previous to its installation, as a consequence of the stress produced, which reduces
the economic losses given the high cost of the ceramic glass.
[0009] The support plate, made of stainless or enameled steel, can be obtained by hammering,
with no prominent angles which could cause its breaking, due to the accumulation of
stress in specific points if it is made with very prominent angles.
[0010] To complement the following description and help to a better understanding of its
features, this memory has a set of charts which show graphically and limitless the
most important details of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1. Shows a general view of the support plate of the ceramic glass that, at
a time, is a decorative element, noticing in its corners the punching made with no
total release of material.
[0012] Figure 2. Shows a detailed view of a section made by an corner of the support plate,
according to the support frame of the ceramic glass, prior to its punching.
[0013] Figure 3. Shows a detailed view of a section made by an angular point of the support
plate, according to the support base of the ceramic glass, after the punching that
causes the partial release of material of the angular point.
[0014] Figure 4. Shows a detailed view of a section made by an corner of the support plate,
according to the support base of the ceramic glass which leans on it.
DESCRIPTION OF A PREFERRED EMBODIMENT
[0015] After seeing the above figures and according to the numbering adopted, we can notice
how the support plate (1) is formed by hammering from a base body that, at a time,
forms a perimeter support frame (2) of the ceramic glass (3).
In the corners of that frame (2) formed by hammering, on which the ceramic glass (3)
leans, a punching has been done to cause the release of material, with a partial breaking,
forming a particle (4) that lies beneath the support level of the ceramic glass, so
its corner does not find the support.
[0016] In this way, the support plate can be formed by slightly prominent angles, thus avoding
breakings, and by causing the partial release of material (4) corresponding to the
same corner of the support frame (2) of the ceramic glass, its contact with the corner
of the support plate is avoided, as well as the breakings of the ceramic glass. All
this means a considerable economic saving given the high cost of ceramic glasses.
[0017] Besides, it is not necessary to round the corners of the ceramig glass (3) and that
reduces its manufacturing cost significantly.
