Description
TECHNICAL FIELD
[0001] The present invention relates to a support for extractable
baking trays and/or baking grids to be arranged in an oven cavity
of a baking oven, comprising pairs of opposed longish guiding means
disposed one above the other and extending along side walls of the
oven cavity, and slide elements comprising receiving means for
receiving a baking tray and/or a baking grid and being slidingly
arranged at the guiding means. Moreover, the present invention
relates to a baking oven comprising such a support.
[0002] Supports of the above mentioned kind are already know in
prior art. DE 103 30 348 B4 for example discloses a baking oven
having a support for extractable baking trays, which comprises a
supporting structure made of a plurality of metal rods and being
fixed to the side walls of an oven cavity. Attached to the
supporting structure are pairs of opposed longish rail-shaped
guiding means, which are disposed one above the other and extend
along side walls of the oven cavity. At each of these guiding means
one longish rail-shaped slide element is slidingly received such
that the slide element is sliding along the guiding means. As
receiving means for receiving a baking tray, the slide elements
comprise upwardly projecting pins, which are insertable in
corresponding openings of a baking tray to be received.
Accordingly, the baking tray can be affixed on top of one pair of
opposed slide elements and can subsequently be pushed in or drawn
out of the baking oven by moving the slide elements along the
associated guiding means.
[0003] A further baking oven having a support of the above
mentioned kind for receiving extractable baking grids is described
in EPA-0 091 666. This support comprises pairs of opposed longish
guiding means, which are disposed one above the other and extend
along side walls of the oven cavity. Each guiding means is formed
by two parallel metal rods of a metal rod supporting structure
arranged within the oven cavity. Moreover, the support comprises
slide elements, each in the form of a L-shaped metal sheet profile,
which are slidingly arranged at the guiding means and are provided
with receiving means for receiving a baking grid. The receiving
means are made integral with the guiding means and are provided in
the form of lugs, which encompass a metal rod of the baking grid to
be received. Accordingly, a baking grid can be affixed to the slide
elements of the support and can be pushed in or drawn out of the
oven cavity by moving the opposed slide elements along the
associated guiding means.
[0004] When extracting a baking tray or a baking grid, which is
received by one of the above mentioned known supports, out of the
oven cavity, the slide elements are at least partially pulled out
along with the baking tray or baking grid, for which reason there
is a danger of getting burned when touching the slide elements, in
particular after a baking tray or a baking grid has been removed
from the slide elements. Moreover, it is difficult to position a
baking tray or baking grid on the slide elements, because the slide
elements can freely move along the guiding means and thus slip
away. This is in particular cumbersome when handling trays or
grids, which are loaded with heavy objects, such as a roasting
tin.
[0005] It is an object of the present invention to provide a
support for extractable baking trays and/or baking grids of the
above mentioned kind as well as a baking oven comprising such a
support, which are safe and easy to handle.
[0006] This object is solved by providing a support of the above
mentioned kind with stopper means in such a manner, that the
extraction sliding movement of the slide elements along the guiding
means is stopped before the slide elements project beyond the oven
cavity. Accordingly, except for the baking trays and/or the baking
grids received by the support, there are no components which can
project from the inside of the oven cavity. Therefore, there is no
danger of getting burned by projecting components of the support,
what renders the support safe and easy to handle.
[0007] Preferably, biasing means are provided, in particular in the
form of at least one spring, for biasing the slide elements towards
the opening of the oven cavity. Thus, the biasing means
automatically move the slide elements towards the opening of the
oven cavity when the oven door is opened, such that a baking tray
or a baking grid received by the slide elements is automatically
extracted. The biasing means are tensioned again when pushing in a
baking tray or grid by closing the oven door.
[0008] According to one embodiment of the present invention at
least two opposed slide elements are interconnected by means of at
least one connecting element in order to achieve a synchronic
movement of these slide elements. Moreover, when biasing means are
provided, the interconnection of the slide elements is advantageous
in that only one biasing means needs to be provided for each pair
of slide elements.
[0009] According to another embodiment, all slide elements are
interconnected by at least one connecting element, preferably a
connecting plate, in order to achieve a synchronic movement of all
slide elements. If biasing means are provided, the interconnection
of all slide elements is advantageous in that only one biasing
means is necessary for biasing all the slide elements towards the
opening of the oven cavity.
[0010] According to one embodiment of the present invention the
receiving means are at least partially punched and subsequently
bent sections of the slide elements, i.e. the receiving means are
at least partially made integral with the slide elements.
[0011] The receiving means can comprise hook elements for
encompassing an upper side of a baking tray and/or a baking grid in
order to prevent a tilting of the tray or grid.
[0012] Moreover, the receiving means can comprise upwardly
projecting receiving elements, in particular welding studs, to be
inserted into corresponding openings provided in the baking trays
and/or baking grids to be received.
[0013] The guiding elements and/or the slide elements are
preferably made of plastics and/or aluminum and/or stainless
steel.
[0014] Moreover, the present invention provides a baking oven
having an oven cavity and an oven door for closing the opening of
the oven cavity and comprising a support of the above defined
kind.
[0015] According to one embodiment at least one protector, in
particular a protector bar or rail, can be provided at the inner
side of the oven door for preventing a contact between a baking
tray and/or a baking grid and the oven door, wherein the at least
one protector is preferably releasably provided.
[0016] The foregoing and other objects of this invention are better
understood by referring to the following detailed description of a
preferred embodiment of the present invention and the appendent
drawing, in which
[0017] FIG. 1 is a sectional view of an oven cavity comprising a
support for extractable baking trays and/or baking grids according
to an embodiment of the present invention, wherein an oven door for
closing the opening of the oven cavity is opened by an opening
angle of about 25.degree.;
[0018] FIG. 2 is a sectional view of the oven cavity shown in FIG.
1, wherein the oven door is opened by an opening angle of about
55.degree.; and
[0019] FIG. 3 is a sectional view of the oven cavity shown in FIG.
1, wherein the oven door is opened by an opening angle of
90.degree..
[0020] The baking oven 10, which is illustrated throughout the
figures without its outer housing to simplify matters, comprises an
oven cavity 12 for receiving food stuff to be cooked. The oven
cavity 12 is defined by two side walls 12a, a back wall 12b, a top
wall 12c and a bottom wall 12d. In the front of the oven cavity 12
an opening 14 is provided, which can be opened and closed by means
of an oven door 16. For receiving extractable baking trays 17 or
baking grids (not shown), a support 18 is arranged within the oven
cavity 12.
[0021] The support 18 comprises a supporting structure 20, which is
made of a plurality of metal rods and is fixed to the side walls
12a of the oven cavity 12. Moreover, the support 18 comprises pairs
of opposed longish rail-shaped guiding means 24, which are disposed
one above the other, extend along the side walls 12a of the oven
cavity 12 and are fixed to the supporting structure 20.
[0022] At each of the guiding means 24 a rail-shaped slide element
26 is slidingly arranged such that it can be moved along the
associated guiding means 24. A contacting surface of each guiding
means 24 and/or of each slide element 26 may be provided with a
slide coating in order to achieve an easy relative motion between
these components. Alternatively, rolling elements, such as balls,
may be arranged between each slide element 26 and the associated
guiding means 14.
[0023] In order to limit the movement of the slide elements 26
along the associated guiding means 24 stoppers 27a, b are formed at
both end portions of each guiding means 24. The stoppers 27a, b are
provided as projections which project from the guiding means 24
towards the slide elements 26 and stop their movement at a
predetermined position. The stoppers 27a, which are arranged at the
front end of each guiding means 24 close to the opening 14 of the
oven cavity 12, are positioned in such a manner that the movement
of the slide elements 26 along the guiding means 24 is stopped
before the slide elements project beyond the oven cavity 12.
Accordingly, except for the baking trays 17 and the baking grids
received by the support 18, there are no components which can
project from the inside of the oven cavity 12. Therefore, there is
no danger of getting burned by projecting components of the support
18.
[0024] Each slide element 26 comprises two receiving means for
receiving a baking tray 17 or a baking grid, namely a hook element
28 for encompassing an upper side portion of a baking tray 17 or a
baking grid, which is formed as a punched and subsequently bent
section of the slide element 26, and an upwardly projecting
receiving element 30 in the form of a welding stud, which is to be
inserted in known fashion into a corresponding opening (not shown)
provided in the baking trays 17 and the baking grids to be
received.
[0025] All slide elements 26 are interconnected by means of
connecting plate 32, which is arranged at the end face of the slide
elements 26 facing towards the back wall 12b of the oven cavity 12.
Accordingly, the movement of the slide elements 26 along the
guiding means 24 is synchronized by means of the connecting plate
32.
[0026] Moreover, the support 18 comprises biasing means in the form
of a spring 36, which is arranged at and guided by the bottom
guiding means 24. The spring 36 biases the connecting plate 32 and
thus the slide elements 26 towards the opening 14 of the oven
cavity 12. Accordingly, the slide elements 26 are automatically
pushed towards the opening 14 of the oven cavity 12 when opening
the oven door 16, as it is shown in the sequence of FIGS. 1 to 3,
such that the baking trays 17 held by the slide elements 26 are
automatically extracted from the oven cavity 12.
[0027] In order to prevent a contact between the baking trays 17
and the oven door 16 when opening and closing the oven door 16, the
latter is provided with a protector rail 38 at its inner side.
Thus, a damage of the inner side of the oven door 16, which is
often formed by a glass plate, can be avoided. The protector rail
38 is releasably fixed to the oven door 16 by means of screws (not
shown).
