Description

IMPROVED DEVICE FOR FIXING A HANDLE TO A CONTAINER FOR COOKING FOOD
The present invention relates to an improved device for fixing a handle to a container for cooking food, in particular, but not exclusively, a frying pan.
As is known, most common containers for cooking food, for instance frying pans, saucepans and pots, are equipped with handles or grips which enable easy handling, even when the container is full and hot. In particular, frying pans are usually equipped with a single elongated cantilever handle, preferably made of a polymeric material, which extends radially from the side wall of the frying pan. The handle is usually fastened, using screws or rivets, to a bridge-shaped fixing device, which in turn is joined to the side wall of the pan by means of screws, rivets or welding.
However, there are disadvantages to using screws or rivets to attach the handle to the respective fixing device. Firstly, screws and rivets can loosen or even break following prolonged use of the cooking container and its handle. In the event of screws becoming loose, only a simple re-tightening operation may be required, however this can still turn out to be bothersome. In the event of rivets loosening or breaking it may instead be necessary to replace the entire pot or pan.
In addition, as a result of the frequent washing that pots and pans are normally subjected to, screws and rivets may be subject to oxidisation if they are not appropriately manufactured in good quality stainless steel, or other rust-proof metallic material. Oxidisation of screws or rivets can not only lead to an unsightly appearance, but can also compromise the cooking process of the food in the pan or pot.
Using screws or rivets to constrain the handle to the respective fixing device requires assembly of numerous components, as well as the use of appropriate equipment for achieving this assembly.
Document US 2 494 159 A illustrates a device for fixing a handle to a container for cooking food wherein such fixing, which is moreover detachable, is made through the mutual movement of a plurality of hooking elements. Such a fixing device is therefore particularly delicate and complex both to produce and use. Additional devices for fixing a handle to a container for cooking food are illustrated, for example, in documents US 4 761 851 A and
US 2005/145637 Al .
The overall objective of the present invention is to provide an improved device for fixing a handle to a container for cooking food, in particular, but not exclusively, a frying pan, which is able to resolve the disadvantages stated in the prior art above in a simple, economical and particularly functional way.
In detail, an objective of the present invention is to provide an improved device for fixing a handle to a container for cooking food which does not require the use of screws, rivets or other similar fixing means to permanently constrain the handle to the respective fixing device.
Another objective of the present invention is to provide an improved device for fixing a handle to a container for cooking food which is able to keep the handle firmly constrained to the respective fixing device .
A further objective of the present invention is to provide an improved device for fixing a handle to a container for cooking food which does not give rise to unwanted phenomena of deterioration of the handle's fixing means, inasmuch as such fixing means are completely absent.
A further objective of the present invention is to provide an improved device for fixing a handle to a container for cooking food which limits the number of components required to constrain the handle to the respective fixing device, thereby simplifying the production process .
These objectives according to the present invention are achieved by providing an improved device for fixing a handle to a container for cooking food, in particular, but not exclusively, a frying pan, as presented in claim 1.
Further characteristics of the invention are highlighted by the dependent claims, which form an integral part of this description.
The characteristics and benefits of an improved device for fixing a handle to a container for cooking food according to the present invention will become apparent in the following description, as a non- exhaustive example, with reference to the accompanying drawings in which:
figure 1 is a perspective view of an improved device for fixing a handle to a container for cooking food according to the invention, applied to a generic pan and on which will be mounted a generic elongated handle ; figures 2, 3 and 4 are sectional views displaying the various methods of interaction between the fixing device according to the invention and the handle, once installed;
figure 5 is a perspective view of just the fixing device according to the invention;
figure 6 is a side elevation view of the fixing device in figure 5;
figure 7 is a bottom view of the fixing device in figure 5;
figure 8 is a front view of the fixing device in figure 5;
figure 9 is a view from the rear side of the fixing device in figure 5;
The figures show an improved device for fixing a handle to a container for cooking food according to the invention, designated by the number 10. The device 10 is configured for permanently fixing a handle 12, for example a handle made of a polymeric material, to the side wall 14 of a generic container 16 for cooking food, for example a frying pan. In other words, the fixing device 10 is not detachable.
The fixing device 10 is integrally manufactured in metallic material, preferably steel. As shown in the various drawings, such fixing device 10 is substantially parallelepiped- shaped and is suitable for inserting, at least partially, into a dead hole 18, which is also substantially parallelepiped-shaped, obtained at the base of the handle 12. When provided in the form of an elongated handle for pans, the handle 12 can be equipped, in a known manner, with a fireproof ferrule or collar 50. The fixing device 10 comprises a first front end 20 formed integrally with a first pair of side walls 22 and 24. Each of these side walls 22, 24 ends with a respective rear end 26, 28 configured so as to be fixed to the side wall 14 of the container 16 with fixing means of a known type .
According to the invention, at least one flap 30 is obtained on each of the side walls 22, 24, protruding outwardly of the fixing device 10 and oriented towards the rear ends 26, 28 of the fixing device 10. These flaps 30 frictionally engage with the internal walls of the dead hole 18 of the handle 12 in order to keep such a handle 12 firmly constrained to the fixing device 10 and to prevent its accidental sliding out under any operative conditions. As shown in figure 2, once the handle 12 has been engaged with the fixing device 10, the particular shape of the flaps 30 makes it possible to oppose a predefined resistance to axial forces which would tend to obtain the sliding out of the handle 12 with respect to the fixing device 10 and, therefore, with respect to the container 16.
The fixing device 10 also comprises a second pair of upper 32 and lower 34 walls, formed integrally with the first front end 20. Each of these upper 32 and lower 34 walls ends with a respective inclined portion 36, 38 which forms a tooth protruding outwardly of the fixing device 10 and oriented towards the rear ends 26, 28 of the fixing device 10. As a consequence, similarly to and in cooperation with the flaps 30, even the inclined portions or teeth 36, 38 frictionally engage with the internal walls of the dead hole 18 of the handle 12 in order to keep such a handle 12 firmly constrained to the fixing device 10 and to prevent its accidental sliding out under any operative conditions, as shown in figure 4.
Each upper 32 and lower 34 wall of the fixing device 10 is provided with an intermediate corner 40, 42 which abuts against a pair of projections 44, 46 obtained respectively on the side walls 22 and 24. The contact of these intermediate corners 40, 42 with the projections 44, 46 allows to obtain a determined elastic deformation of the inclined portions or teeth 36, 38 in order to improve its friction conditions due to interference inside the dead hole 18 of the handle 12.
On at least one of the edges of the side walls 22 and 24, preferably the lower edge, are also obtained one or more protruding teeth 48 which also frictionally engage with the internal walls of the dead hole 18 of the handle 12 in order to keep such a handle 12 firmly constrained to the fixing device 10 and to prevent its accidental sliding out under any operative conditions, as shown in figure 3.
During assembly, once the handle 12 has been press- fitted to the fixing device 10, the combined action of the hooking elements of such a fixing device 10 which frictionally engage with the internal walls of the dead hole 18 of the handle 12, that is to say the flaps 30, formed integrally with the side walls 22 and 24, the inclined portions or teeth 36 and 38, formed integrally with the upper 32 and lower 34 walls, and the protruding teeth 48, formed integrally with one or both of the edges of the side walls 22 and 24, ensure the handle 12 is securely and firmly attached to the fixing device 10. It is therefore not necessary to use any fixing means (screws, rivets or other) , with all the economic and production advantages that this affords. The ability to manufacture the fixing device 10 in a single unit in moulded metal ensures strength and resistance in the use of such fixing device 10 and also contributes to reductions in assembly times and costs.
It is therefore understood that the improved device for fixing a handle to a container for cooking food according to the present invention achieves the objectives previously set out.
The improved device for fixing a handle to a container for cooking food of the present invention is subject to various modifications and variations, all falling within the same inventive concept; furthermore, all details can be replaced with technically equivalent elements. In practice the materials used, as well as the shapes and dimensions, may be adjusted in accordance with technical requirements.
The scope of protection of the invention is therefore defined by the attached claims.
