Safety device for cooking hobs to prevent vessels from overturning when cooking

Description

[0001] The present invention relates to a safety device, to be applied to cooking hobs provided with gas-­burners or electric hot-plates, and being either of the built-in type to be recessed in a piece of furniture or formed of a household cooker top, which is capable of preventing vessels placed on the hob itself from overturning, in particular when cooking foods.

[0002] It is known that the vessels used for cooking, and especially pots having a considerable height in comparison with their diameter, are susceptible to overturning when accidentally struck and of fall­ing from the cooking hob, thus pouring the liquid therein, often boiling. This leads to a dangerous situation for people standing near by, especially when children are present who, besides causing this type of accidents more frequently, due to their restlessness and less care taken, may be burnt more seriously by the poured liquid, owing to their height which ap­proximately corresponds to the hob level.

[0003] It is true that sometimes attempts have been made to anchor vessels onto the support top surface, such as by means of snap fastening devices, which however have proved to be complex and/or cumbersome, with the additional drawback of easily heating while cooking, so as to be difficult to handle when these devices have to be released for leaving free the associate vessel as soon as the cooking is over.

[0004] Other anti-tilting devices are known, for the above-mentioned purpose, being formed of a protective metal section which, at a front position, restrains onto the hob the vessels placed over the burners. However these known devices show various disadvan­tages, such as the fact that at rest, in the backward position they are situated over the rear burners or anyway due to their overall dimensions are of hin­drance to the complete lowering of the cover onto the cooking top. In addition sometimes these devices comprise a plurality of members and thereby con­structional complications are required to keep, during operation, a higher position with respect to the cooking top surface that is more efficient against the tilting of the adjacent vessels.

[0005] From DE-C-859 060 a device is known to prevent vessels placed on a cooking hob, from being acciden­tally overturned, comprising a number of metal bars substantially parallel to each other and to the front edge of the hob, which are connected on each side to respective arms being hinged at the back side of the cooking hob. Such a device however can­not be used with a hob having a tiltable cover which is also hinged at the back side of the hob.

[0006] An object of the present invention is therefore that of providing an anti-tilting device for pots and the like, which is easily applicable onto cook­ing surfaces, of simple construction in a single piece and of good functional capacity and handiness, without the need of a releasing operation for leaving free vessels, while being at the same time perfectly reliable and capable of allowing, at a rest condition, the hob cover to be lowered without interference therewith.

[0007] Such an object of the invention is obtained with a device according to the characterizing features of the claim.

[0008] US-A-4 583 518 shows a device of a similar confi­guration to that described in the present claim as to the approximately middle position of hinges and the profile of the lateral shaped arms, but such a device is applied by hinging to the lower extremity of a space heating appliance in the vertical plane for the purpose, completely different from the tech­nical problem of this invention, of maintaining a minimum gap between the heater and combustible ob­jects such as furniture.

[0009] For a better understanding of the present in­vention through a preferred embodiment thereof, by way of example, reference will be made to the fol­lowing description and drawing, the single figure of which shows a perspective view of a hob provided with a device of the invention.

[0010] With reference to the figure, a device 2 accord­ing to the invention is mounted to a cooking hob 1 which may be either of the built-in type to be recessed in a piece of furniture there­under, or such as to form the top plane of a self­-contained cooker, being here represented with gas­-burners, whereas it could also comprise at least one electric hot plate. The device comprises shaped metal bar, hinged at its end portions 3, 3ʹ to the elevated side edges 4, 4ʹ of the hob at approximately the middle zone along the direction of depth of the hob itself. Preferably the bar form­ing the device 2 has a round cross-section, so that its end portions 3, 3ʹ can rotate freely in associate holes formed in the side edges 4, 4ʹ without the necessity of separate hinges.

[0011] At position A the device 2 has been shown by continuous lines as in use, i.e. turned to the front side of the hob, whereas at position B it is turned rearwards, in a rest situation. The device 2 sub­stantially comprises a metal bar 6, substantially rectilinear and parallel to the front edge or width side of the hob, being joined at each side to the associate end portion 3, 3ʹ, useful as a hinger through a shaped arm, respectively 8, 8ʹ.

[0012] The protection against possible tilting or over-­turning of vessels on the front burners of the cook­ing hob 1 is mainly provided by the elongated bar 6 which, thanks to a particularly angled shape of the side shaped arms 8, 8ʹ, with parts 5, 5ʹ results to be raised with respect to the hob, thus forming an actual hindrance to a forward tilting of the vessels on the front burners. At the same time also the shaped arms 8, 8ʹ give a protection, even if partial, against a possible tilting in a lateral direction.

[0013] Furthermore the particular configuration of the shaped arms 8 is useful to a lateral grasping of the device to cause it to rotate from position A to B and vice versa.

[0014] The shaped arms 8 are upwardly bent at A, starting from parts 5, 5ʹ which are slightly recessed to the inside with respect to the end portion 3, 3ʹ and pa­rallel to the side edges 4, 4ʹ of hob 1. Such a configu­ration, when the device 2 is rotated backward by 180° to the position B, causes the elongated bar 6 to completely rest on the rear side of the hob, while the shaped arms 8, 8ʹ remain partially raised therefrom. A designer will then be able to dimension the various parts so that the height by which arms 8, 8ʹ are raised at the position B will be within the tolerance range allowed between hob and cover 10 without hindering the complete lowering of the lat­ter.

[0015] It is clear that a safety device as described and illustrated can be easily applied to whichever cooking hob having upraised lateral edges of suf­ficient height, and affords an extremely good handi­ness and ease of utilization without showing the known drawbacks due to an excessive heating, when it is also considered that the vessels thereby pro­tected from overturning can be removed from the burners, upon cooking, without the necessity of touching by hands the device itself. In fact the same does not prevent pots and the like from lifting from the rest surface, but only from tilting, espe­cially towards the front side.
