BACKGROUND OF THE INVENTION
[0001] The present invention relates to a control device for controlling faucets for cooking
implements or planes.
[0002] In conventional cooking implements and gas ovens, the control panel for controlling
the burners is arranged on the front of the implement, and the burner faucets are
arranged at a remote position with respect to the control knobs.
[0003] The latter, in particular, are arranged on the front panel of the cabinet supporting
the cooking plane or surface and, at the bottom, the oven.
[0004] Accordingly, it is necessary to properly connect the control knobs to the faucets.
[0005] A prior solution for performing this connection is that of using control or driving
rods including two cardanic couplings.
[0006] At present, some regulations, for example the CEE Regulations, provide that, for
safety reasons, the opening of the faucet by a rotary movement of their control knobs
be possible exclusively upon exerting an axially directed pressing force on the control
knob.
[0007] Thus, it is necessary to use control rods having an adjustable length, thereby to
fit said control rods to the different size of the kitchen cabinets and to allow to
provide an axial pushing or pressing force from the control knob to the faucet.
[0008] Said control rods have a conventional telescopic construction and must be provided
with locking elements comprising ring nuts or clamps.
[0009] The locking elements used in control devices of the prior art, however, require very
complex assembling operations, since they are usually arranged at an inaccessible
region of the implement cabinet, which is delimited, at the top, by the cooking plane
and, at the bottom, by the oven.
SUMMARY OF THE INVENTION
[0010] The aim of the present invention is to provide a control device for controlling faucets,
for cooking implements, which overcomes the above mentioned drawbacks of the disclosed
prior art.
[0011] Within the scope of the above mentioned aim, a main object of the present invention
is to provide such a control device which can be quickly and easily installed, without
the need of using specifically designed tools or means.
[0012] Another object is to provide such a control device which is very advantageous from
a mere economic construction standpoint.
[0013] Another object of the present invention is to provide such a control device which
is very flexible in operation and can be used in several types of cooking implements.
[0014] According to one aspect of the present invention, the above mentioned aim and objects,
as well as yet other objects, which will become more apparent hereinafter, are achieved
by a control device for controlling faucets for cooking implements, characterized
in that said control device comprises a telescopic rod, including at least a first
bar and a second bar sliding within the first bar, and coupling a control knob to
a faucet, said second bar including locking means for locking said second bar with
respect to said first bar, said locking means comprising a sliding block which can
slide on the second bar in a direction only.

not exclusive, embodiment of the invention which is illustrated, by way of an indicative,
but not limitative, example, in the accompanying drawings, where:

Figure 6 is a view, similar to the preceding view, but showing the subject control

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] With reference to the number references of the above mentioned figures, the control
device, according to the present invention, which is generally indicated by the reference
number 1, comprises a telescopic rod, including a first bar 2 and a second sliding
bar 3 which can slide, at least partially, in said first bar 2.
[0017] The free end portions of the bars comprise each a cardanic coupling, 4 and 5, being
respectively coupled to a faucet 6 and a control assembly 7, operated or driven by
a control knob 8.
[0018] The control assembly 7 and knob 8 are associated with a front panel 9 of a cabinet
10 comprising, at the top, a cooking plane or surface 11 supporting burners 12, including
respective burner faucets 6, of which, for clearness, only one has been shown in the
drawings.
[0019] Under the cooking plane 11 an oven 13 is arranged, in a per se known manner, thereby,
for assembling the cabinet, the first bar is usually coupled to the first faucet 6,
before assembling the cooking plane 11, whereas the second bar 3 is fixed to the control
assembly 7 including said control knob, 8 before clamping the front panel 9 to the
cabinet frame.
[0020] Thus, as said bars are mutually slidably driven, the length of the telescopic rod
is automatically adjusted, based on the distance existing between the control assembly
7, on the front panel 9 and the faucet 6.
[0021] However, since, for driving the faucet 6 by the control knob 8 is necessary to apply
an axially directed pressing force, before performing the rotary movement of the knob,
the mutual sliding of the two bars 2 and 3 must be prevented or locked.
[0022] To that end, according to the present invention, is provided a means for locking
the second bar with respect to the first, said means comprising a small block 14 which
can slide unidirectionally on the second bar.
[0023] The block 14 comprises, to that end, an interference means, including a spring 15,
having opposite fins 16, for interfering against the bar 3 to allow said bar 3 to
slide unidirectionally, and, more precisely, in the extension direction of the telescopic
rod, but not in the opposite direction.
[0024] More specifically, the small block 14 comprises a longitudinally extending recess
17 in which said bar 3 slides, and an annular recess 18, in which said spring 15 is
engaged.
[0025] The latter can comprise two opposite fins or wings 16, as in the shown embodiment,
or a different number of wings, depending on requirements, provided that said wings
allow, owing to their slanting, the bar 3 to slide in the telescopic rod extension
direction.
[0026] Thus, the small block 14 allows to lock the telescopic rod, constituted by the bars
2 and 3, at the desired length thereof, after having automatically adjusted the length
of telescopic rod by mutually causing the bars to slide with respect to one another,
based on the distance or spacing existing between the control knob assembly 7, on
the front panel 9, and the faucet 6.
[0027] The locking of the telescopic rod can be performed through an opening on the front
panel by operating, by a screwdriver or other elongated tool, on the block 14 which
can be pushed, by causing it to slide along the bar 3, so as to abut against the end
portion of the bar 2.
[0028] In this position, the wings 16 will prevent, by abutting, any further rightward sliding
of the block 14, as shown in the figures.
[0029] Accordingly, as the bar 3 is axially pressed, leftward with respect to the figures,
then this pressing force will be transferred, through the block 14, to the bar 2 and
accordingly to the faucet 6.
[0030] It has been found that the invention fully achieves the intended aim and objects.
[0031] In fact, the invention provides a control device for controlling faucets for cooking
implements or planes, which can be installed in a much more quick and easy manner
than in prior devices, and without using specifically designed tools or instruments.
[0032] In practicing the invention, the used materials, as well as the contingent size and
shapes, can be any, depending on requirements and the status of the art.
