Definitions

  • the present invention relates to a safety device for opening the door of a domestic cooking appliance, in particular an oven, built-in or not, or even a stove.
  • the systems known at present are installed on the handle of the oven door. This has the obvious advantage of allowing the user to open the door with one hand. On the other hand, however, a given security system integrated into the door handle cannot be transposed as such to another range of cooking appliances for which, for reasons notably of aesthetics, the handle will have a different shape.
  • the known safety means consist in lateral actuation of a device, generally from the left towards the right.
  • This type of device is very well suited to users who are right-handed, while it turns out to be a nuisance for left-handers.
  • the present invention aims to provide a safety device operating on the principle of double manipulation, but which does not have the drawbacks mentioned above.
  • the invention relates to a safety device for opening the door of a cooking appliance, said door comprising a handle, the safety device being characterized in that it comprises a lever accessible at the front of the cooking appliance and capable of being rotated about an axis substantially parallel to the axis of rotation of the door and mounted on the chassis of the apparatus, and a stop extending from the axis towards the interior of the apparatus and having a free end, said stop being integral with the lever rotating about the axis , the safety device being capable of being in a first so-called activated position, in which the free end of the stopper obstructs the passage of a keeper situated on the contour of the door when the latter is opened , and in a second so-called deactivated position, obtained by manual movement of the lever towards the handle, driving the stop in rotation about the axis so as to move the free end of the stop away from the door, and free the passage of spoils.
  • the same device can be used for several ranges cooking appliances, regardless of the aesthetics that you want to give to the front of the appliance.
  • the movement of the lever can be done easily, whether the user is right-handed or left-handed.
  • the safety device can be neutralized by voluntary action by the user.
  • the device according to the invention may further comprise means capable of placing the safety device in a so-called neutralized state, in which the stop is, relative to the lever, in an angular position such that the passage of the keeper is always released, regardless of the position of the lever.
  • FIGs 1a and 1b there is shown partially, in side section, the front face of a cooking appliance with a flap door 1, equipped with a safety device according to the invention.
  • the handle 2 In the case of a drop-down door, the handle 2 is horizontal.
  • the safety device comprises on the one hand a lever 3 accessible to the user at the front of the device, and a stop 5.
  • the lever 3 and the stop 5 are integral in rotation around a fixed axis 4 to frame C of the cooking appliance, and extending parallel to the door handle and to the axis of rotation of the door.
  • the safety device In the activated position shown in FIG. 1a, the safety device is such that the free end 5a of the stop rests on the upper part of the door. According to the invention, this free end comes in this position to obstruct the passage of a keeper 6 located on the upper part of the door. It is therefore not possible for a user to open the door as long as the safety device is activated.
  • a return spring 7 allows the safety device to automatically return to its activated position as soon as the user no longer presses the lever.
  • the movement, automatic or not, of the lever 3 in the opposite direction to the arrow F 1 is preferably limited, for example by a flange 8 fixed to the chassis C of the device, on which the lever 3 abuts.
  • a particularly advantageous embodiment of the safety device consists in providing the lever 3 and the stop 5 in the form of two separate parts mounted free in rotation around the axis, and secured in rotation by particular shapes given to these two parts. More precisely, the lever 3 has a first shoulder 30 on which an extension 50 of the abutment extending along the axis 4 rests. The way in which this extension comes to bear allows the two parts to be secured in rotation and to have a relative angular positioning making it possible, when the lever 3 is actuated in the direction of the arrow F 1 (FIGS. 1b and 2a), to drive the stop in rotation over an angular path sufficient to release the strike plate 6.
  • the safety device furthermore comprises means which make it possible to neutralize the safety device voluntarily and simply, that is to say to position the stop angularly relative to the lever so that 'It never obstructs the passage of the striker, and this, whatever the position of the lever, and in particular when the latter is not actuated by the user.
  • the lever 3 comprises a second shoulder 31 on which the extension 50 of the stop 5 is capable of coming to bear ( Figures 2b and 3b).
  • the user who wishes to neutralize the safety device manually moves the stop 5 in rotation about the axis 4, as indicated by the arrow F 2 in FIG. 2b.
  • This action frees the extension 50 from the first shoulder 30.
  • the lever is also capable of being manually translated along the axis 4. By this translation, the extension 50 is brought to bear on the second shoulder 31. The way in which comes to bear this extension again allows the two parts to be secured in rotation.
  • the angular positioning of the stop and the lever is such that the end 5a of the stop can never obstruct the passage of the strike, even when the device is supposed to be in an activated position.
  • the present invention has been described in the context of a cooking appliance with a drop-down door. Of course, the system can easily be transposed to doors with lateral opening.
