Definitions

  • the present invention relates in general to a device for protecting access to a cooking top, and to the cooking top comprising the device.
  • the present invention relates to a protection device applicable to a cooking top for kitchens for instance provided with electric stoves or gas cookers, in order to protect persons at risk, for instance children and elderly people, from approaching the cooking top and, particularly, containers laying on the cookers and/or stoves of the cooking top while food is being cooked.
  • Safety devices are known in the art, for protecting the access to a cooking top.
  • a protection device is known from patent application AU-A-59355/86 arranged so as to protect access to the cookers and/or stoves of a cooking top.
  • the known device is hinged to a base and is suitable for reaching a "rest" position, in which the device is in a substantially vertical position, and an "operating" position in which the device is in a substantially horizontal position and protects, by means of its own structure, the cooking top and the cookers and/or stoves from being reached by persons at risk.
  • the known device as well as other similar devices such as the one described in the patent publication FR_2610704 , have the common problem that the front obstructing surface suitable for protecting access to the cookers and/or stoves in the "operating" position, becomes, in the "resting" position, an obstructing surface that prevents or renders difficult suction of cooking-smokes or -vapors and the lighting of the cooking top.
  • the poor suction can imply, for instance, that the vapors cause accumulation of dirt on the safety device, bad smells or similar effects.
  • the poor lighting of the cooking top can involve the need of keeping the device permanently in the "operating" position.
  • a further problem of known devices is that they require that in the "resting" position blocking elements are provided suitable for stabilizing the substantially vertical position of the safety device; of course the blocking elements in the "resting" position can also consist of a wall facing the cooking top.
  • An object of the present invention is a device for protecting access to a cooking top which, even though providing a large protecting surface in the "operating" position, provides a minimum obstructing surface with respect to the smoke flow and to the lighting of the cooking top in the "resting" position.
  • Another object is a device that in the "resting" position does not need blocking elements suitable for stabilizing the device itself.
  • the invention also relates to a cooking top comprising the device according to the invention.
  • the device according to the invention comprises a frame having an articulated quadrilateral structure, so that shifting from the "operating" position to the "resting" position is made so that the front obstructing surface, suitable for protecting the cookers and/or stoves to be reached, does not become an obstacle to smoke suction and/or to lighting.
  • the frame of the device comprises at least a pair of bars that in the "operating" position are substantially parallels to the cooking top and spaced from each other and that in the "resting" position are substantially orthogonal to the cooking top, for instance arranged at about 5° sexagesimal degrees beyond the vertical, and in contact eith each other so as to keep the device in stable and vertical position with no need of blocking elements.
  • a device 10 for protecting access to a cooking top 12 comprises, in the preferred embodiment, one pair of supporting elements 14a and 14b respectively, and a frame 15 releasably connected, by a fitting, to the pair of supporting elements 14a and 14b.
  • the supporting elements 14a and 14b are fixed to the cooking top 12 that is preferably fitted in a known way in a base (TOP) 21 (Figure 1, Figure 2) of a kitchen and comprises a plurality of cookers and/or stoves 23 of known type, such as gas cookers or electrical stoves, and respective knobs 25 (Figure 2, Figure 3), known per se, suitable for controlling the operation of the cookers and/or stoves 23.
  • TOP base
  • Figure 1 a base
  • knobs 25 Figure 2, Figure 3
  • each supporting element 14a, 14b comprises respective fastening elements 41a, 41b ( Figure 1, Figure 2), suitable for allowing the supporting element 14a or 14b to be fixed to the cooking top 12, for instance with screws, and respective fitting elements 43a and 43b suitable for allowing the frame 15 to be releasably fixed by fitting to the supporting elements 14a and 14b.
  • the fitting elements 43a and 43b can be made for instance with a "U" female shape, and can exdend orthogonally to the cooking top 12 for a length sufficient for housing, as it will be hereafter described in further detail, a bearing element 51 of the frame 15 and for coupling said frame 15 to the cooking top 12.
  • the supporting elements 14a and 14b are arranged at opposite ends of a side of the cooking top 12 and arranged with the fitting elements, 43a and 43b respectively, facing one another so as to be able to perfectly house the bearing element 51 of frame 15.
  • the supporting elements 14a and 14b can be made up of supporting elements already existing in the cooking top 12 in order to support a possible cover of the cooking top 12.
  • the supporting elements can be integral with the bearing elements and fixed either to the cooking top 12 or, for instance in the case of cooking tops already installed, to the TOP 21, even by maintaining the function of putting in positioning relation the cooking top 12 with the device 10 or with the frame 15.
  • the frame 15 comprises the bearing element 51, a screen (shield) 53 and two pairs of bars, a first pair of bars 155a, 255a, and a second pair of bars 155b, 255b respectively, having their end hinged, as it will be described later on in detail, to the support 51 and to the shield 53 respectively so as to form an articulated quadrilateral structure.
  • an articulated quadrilateral structure comprises structures provided with four bars connected with one another by means of hinges so as to form a quadrilateral.
  • the bars can have different lenghts, or they can also be equal and opposite in pairs.
  • the frame is made of aluminum material but, as a technician skilled in the field can easily understand, also other materials can be used such as light metal alloys, for instance for the bars, or glass, for instance for the shield.
  • the bearing element 51 comprises a bar 61, a pair of brackets 64a and 64b respectively, and a pair of embedding frame elements 63a and 63b respectively, arranged so that they can be embedded, in a known way, in the fitting elements 43a and 43b of the supporting elements 14a, 14b.
  • brackets 64a and 64b and the embedding frame elements 63a and 63b are respectively fixed to or formed on the opposite ends of the bar 61 that has a length substantially equivalent to the width of the cooking top 12.
  • each bracket 64a, 64b comprises two hinges 164a, 264a and 164b, 264b respectively, arranged according to a configuration determined by distances D1 and D2 respectively parallel (in a horizontal direction) and orthogonal (in a vertical direction) to the cooking top 12 and suitable for forming a articulated quadrilateral structure, through the bars 155a, 255a and 155b, 255b, hinged to respective hinges 164a, 264a and 164b, 264b.
  • the distances D1 and D2 between the hinges can be, for instance, of about 25 millimeter in horizontal and 40 millimeter in vertical, respectively.
  • the shield 53 comprises or is shaped so as to to form a front wall 71, for instance not permeable, and two side walls, 74a and 74b respectively, for instance not permeable they too and, as it will be illustrated in further detail hereafter, when the device 10 is in operating position is suitable for protecting the cookers and/or stoves 23 from being accessed, for instance, by persons at risk such as children or elderly people.
  • the shield 71 ( Figure 3, Figure 4) can comprise through holes 71a, having for instance circular or rectangular cross-section, suitable for making flow of air or comburent easier for feeding, in particular, the cookers and/or stoves 23 near the shield 71.
  • the through holes 71a are arranged preferably at a height corresponding to or a little lower than the height of cookers and/or stoves 23.
  • the front wall 71 of the shield 53 preferably comprises a handle 73 ( Figure 2, Figure 3) made for instance by bending the front wall 71, and pointing preferably towards the cooking top 12 (inside of the device or the shield) when the device 10 is in operating position, so as not to be reachable by people at risk, such as children.
  • a handle 73 Figure 2, Figure 3
  • each side wall comprises two hinges, 174a, 274a and 174b, 274b respectively, arranged with a configuration substantially identical or equivalent to the one already described for the hinges 164a, 264a and 164b, 264b comprised in the brackets 64a and 64b.
  • the shield 53 can comprise a seal 75, for instance made of a rubber material, suitable for resting on the TOP 21 of the kitchen, when the device 10 is in operating position, and for slowing down a possible liquid flow, for instance boiling liquids, overflown from pots in the zone of cookers and/or stoves 23.
  • a seal 75 for instance made of a rubber material, suitable for resting on the TOP 21 of the kitchen, when the device 10 is in operating position, and for slowing down a possible liquid flow, for instance boiling liquids, overflown from pots in the zone of cookers and/or stoves 23.
  • the shield 53 can also comprise two recesses 76a and 76b respectively, ( Figure 1, Figure 3) at the base of the side walls 74a and 74b, the recesses too being provided for instance with rubber material seals, shaped so as to provide a light pressure sealing on the side walls of the cooking top 12.
  • the shield 53 can have quite variable height dimensions, according to space- and use needs.
  • the Applicant thinks that optimal height dimensions can range between 135 and 175 milimeter, but other dimensions bigger or smaller than the quoted values can be used.
  • the bars 155a, 255a and 155b, 255b have first ends, not numbered, hinged in a known way to the brackets 64a and 64b by the hinges 164a, 264a and 164b, 264b, and second ends, not numbered, hinged in a known way to the side walls 74a and 74b, of shield 53, preferably to the inner walls to device 10, by the hinges 174a, 274a and 174b, 274b respectively, so as to form an articulated quadrilateral.
  • the bars 155a, 255a and 155b, 255b are suitable for rotating with fulcrum on the hinges 164a, 264a and 164b, 264b of the brackets 64a and 64b, around the supporting element 51, from a position in which the bars are substantially parallels to the cooking top and spaced one from another to a position in which they are substantially orthogonal to the cooking top and in contact.
  • a position of the device 10 ( Figure 1, Figure 2, Figure 3) hereafter referred to as, conventionally, "operating position", is taken as reference, for describing the operation.
  • the device 10 with its frame 15 is arranged so that the shield 53 rests on the TOP 21 of the kitchen.
  • the frame 15 has, for instance, its bars 155a, 255a and 155b, 255b, arranged substantially parallel to the cooking top 12, and the shield 53 is arranged in a position substantially orthogonal to the cooking top 12.
  • the shield 53 protects, by means of the front wall 71, that people at risk such as children or elderly people touch pots exposed to high temperatures or knock them over. Moreover the shield 53, since it rests on the TOP 21 of the kitchen, does not offer grips for lifting and only an adult can reach the handle 73 advantageously arranged inside the shield 53.
  • the shield 53 also protects peaple at risk from reaching the knobs 25 that control the operation of cookers and/or stoves 23, while, at the same time, does not impede an adult from reaching said knobs 25.
  • the presence, preferably, of the sockets 76a and 76b suitable for providing pressure sealing on the side walls of the cooking top 12, can be helpful in order to ensure that the shield 53 is not movable across the direction of the bars (laterally) and therefore ensures a high stability of the device 10 in the operating position.
  • the bars 155a, 255a and 155b, 255b shift from a position in which they are substantially parallel to the cooking top 12, to a position in which they are substantially orthogonal to the cooking top 12, whereas the shield 53, thanks to the articulated quadrilateral structure of the frame 15, stays arranged in a substantially constant (orthogonal) position relative to the cooking top 12 during the whole rotation.
  • substantially orthogonal and parallel in the present description is used for referring to positions substantially equivalent, with a certain degree of approximation, for instance some sexgesimal degrees, to conditions of parallelism and orthogonality.
  • the shield 53 thanks to the substantially orthogonal position, provides, as a technician skilled in the field can easily understand, minimum resistance to a possible smoke- or vapor flow and does not prevents lighting from the top of the cooking top 12.
  • the device 10 advantageously is in a stable position since the bars 155a, 255a and 155b, 255b, come to contact self-supporting themselves and the shield 53.
  • the reached resting position in the preferred embodiment is both a condition limiting the rotation of the device and a no-spontaneous-return condition to the operating position.
  • the quadrilateral can be articulated also by means of a single pair of bars hinged to a flange arranged, for instance, centrally with respect to both the support element and the shield.
  • the pins to which the bars are hinged can comprise clutch discs of known type, suitable for allowing controlling the effort needed for shifting from the operating position to the resting position and viceversa.
  • the described device can be applied to any kind of cooking top, with knobs arranged both in a front- and side zone.
  • the device moreover, thanks to the presence of suitable embedding frame elements, can be easily fixed to or removed from the cooking top.
