Definitions

  • the invention consists of a device which enables control of the tap of a burner, equipped with a safety valve, belonging to a built-in multi-purpose gas cooking surface.
  • the shaft of the knob which controls the tap that regulates gas flow to one of the burners of the cooking surface is connected to the shaft of the tap by a variable-length rod comprising adjustable means which enable the minimum length of the rod to be set, the rod thus being able to transmit to the shaft of the tap the axial force required to disable a safety valve built into the bumer.
  • Multi-purpose built-in cooking surfaces and ovens are known and available on the market, which, when installed in association with one another, make up an assembly in which also the controls of the burners of the cooking surface are located on the front of the oven.
  • This arrangement is advantageous for the user in that it makes it possible to increase the space available for arranging the burners and grills, but involves the problem of connecting mechanically each knob located on the front of the oven with the tap that regulates gas flow to the corresponding bumer.
  • the said tap is located in the bottom part of the cooking surface at a distance from the corresponding knob which is different for each tap and depends upon a number of factors, such as, for example, the position of the cooking surface with respect to the kitchen working surface, the thickness of the kitchen working surface, the height at which the oven is installed, etc.
  • variable-length rod comprising two or more parts which are free to slide with respect to one another
  • particular universal joints one of which is fixed to the tap shaft, and the other to the knob shaft.
  • variable-length rod Normally one end of the variable-length rod is fixed to the tap shaft before the cooking surface is inserted into the cabinet, whilst the other end of the variable-length rod (preferably, but not necessarily, completely extended to enable easier access to the rear part of the oven front) is fixed to the knob shaft before the oven front is inserted into the cabinet.
  • each variable-length rod When the front of the oven is inserted into the cabinet, the mutual sliding of the parts that make up each variable-length rod automatically adjusts the length of the rod to the distance existing between the shaft of the knob and the shaft of the tap to which it is fixed.
  • Each variable-length rod is designed to transmit to the tap shaft a rotation exerted by the user on the knob to regulate the intensity of the flame, but is not able to transmit to the tap shaft an axial force.
  • EP A 412 041 discloses a control mechanism for connecting a control button to a cook comprising a double articulation and an axis comprising two elements able to reciprocally slide. Said axis can transmit rotation, but not a longitudinal movement.
  • GB 827,650 discloses a control device wherein two shafts, for transmitting rotation from a knob to a control mechanism of an oven, are free to slide reciprocally. The device does not allow any other movement than rotation.
  • the shaft of a knob is connected to the shaft of the tap by means of a variable-length rod which is not able to transmit to the tap shaft the pressure exerted by the user on the knob. It is not therefore possible to equip a multipurpose cooking surface with burners each comprising a safety valve.
  • the control device which is the subject of the present invention makes it possible to overcome the serious problems referred to above in that it is able to transmit to the shaft of the tap not only a rotation exerted by the user on the knob to regulate the intensity of the flame, but also a pressure exerted by the user on the knob.
  • the subject of the present invention is a device for controlling a tap equipped with a safety valve belonging to a multipurpose gas cooking surface, the said tap comprising a variable-length rod consisting of a first rod telescopically inserted into a second rod in which it is free to slide.
  • the free ends of the first rod and of the second rod carry fastening means (comprising a universal joint) for coupling them mechanically to the shaft of the control knob and to the tap shaft, respectively.
  • the device further comprises a friction slide inserted on the first rod, said friction slide further comprising means designed to fix it in a reversible way to the first rod and a leaf spring inserted between one inner wall of the slide and the adjacent outer wall of the first rod.
  • FIG 1 is a schematic representation of an assembly comprising a multipurpose oven 5 and a multipurpose cooking surface 1, built into the same cabinet, in which the knob 4 located on the front of the oven 5 is connected to the tap 2 of one of the burners of the cooking surface 1 by the control device 3 (which will be better described in the exploded view of Figure 3), which comprises a variable-length rod consisting of one first rod 31 telescopically inserted into one second rod 32, inside which it is free to slide.
  • the free ends of the two rods (31, 32) are mechanically coupled to the shaft of the knob 4 and to the shaft of the tap 2, respectively.
  • blocking means 33 (consisting, in the preferred embodiment described herein, of a friction slide, which will be better described with reference to Figure 3) which can be adjusted to set the minimum length of the variable-length rod.
  • FIG 2 is an enlarged partial schematic view of the assembly of Figure 1 and has the purpose of better illustrating the knob 4 connected to the tap 2 of the burner of the control device 3 consisting of the first rod 31 telescopically inserted into the second rod 32 (in which it is free to slide) and of the friction slide, inserted on the first rod 31, which constitutes the blocking means 33.
  • the free ends of the two rods (31, 32) are mechanically coupled to the shaft of the knob 4 and to the shaft of the tap 2, respectively.
  • Figure 3 is an exploded view of a control device 3 made according to the invention.
  • the first rod 31, the second rod 32, the friction slide that constitutes the blocking means 33, and the fixing means 34 located at the free ends of the two rods (31, 32) and designed to couple them mechanically to the shaft of the knob 4 and to the shaft of the tap 2, respectively.
  • the friction means of the slide consist of a leaf spring 35 inserted between one inside wall of the slide and the adjacent outer wall of the first rod 31.
  • the leaf spring 35 it is possible to replace the leaf spring 35 with another, functionally equivalent, elastic element, not described herein in that it is in itself known.
  • the leaf spring 35 may be seen both by itself and inserted into the friction slide.
  • the friction slide moreover comprises fixing means 36 (consisting, in the example of embodiment illustrated herein, of a screw inserted into a threaded hole made in one wall of the friction slide) that are designed to fix the slide in a reversible way to the first rod 31.
  • each variable-length rod is fixed (by means of the fixing means 34) to the shaft of the tap 2 of one of the burners of the cooking surface 1; each variable-length rod is extended, and the other end of the rod is fixed (using the fixing means 34) to the shaft of the, corresponding knob 4 located on the front of the oven 5 before the oven 5 is inserted into the cabinet.
  • the oven 5 is set into the cabinet but not fastened in its housing.
  • Each variable-length rod automatically adapts its length to the distance between the shaft of the knob 4 and the shaft of the tap 2 to which each one is fixed.
  • the mutual displacement of the second rod 32 with respect to the first rod 31 causes the slide to run along the first rod 31. Since the slide is a friction slide, it remains in the position that it reaches when the oven 5 is completely inserted into the cabinet, even when the oven 5 is taken out again.
  • the oven 5 is inserted into the cabinet and fastened in its housing.
  • the second rod 32 comes to bear upon the slide which is fixed to the first rod 31, thus limiting the minimum length of the variable-length rod to the effective distance between the shaft of the knob 4 and the shaft of the tap 2.
  • the rod is able to transmit to the shaft of the tap 2 also the axial force exerted by the user on the knob 4 to disable the safety valve when he lights the bumer.
