FIELD OF THE INVENTION

This invention relates to a lining for an element of a barbecue and to a process for realizing a lining.

The invention also concerns a process for engaging a lining to an element of a barbecue.

This invention also relates to the use of a lining.

The invention refers also to a kit, an assembly and a barbecue assembly, each of which includes at least one lining.

The invention finds advantageous application in the technical field of barbecues and in particular barbecue accessories.

STATE OF THE ART

Barbecues allowing you to cook, and in particular to grill, food are known. Known barbecues have a cooking chamber inferiorly delimited by a bottom defining the combustion chamber and superiorly delimited by a lid. In charcoal barbecues, the bottom usually houses two grills arranged on different levels; one grill is arranged at a lower level and is used to support charcoal, while the other grill is arranged at a higher level and is used to support food.

Some known barbecues have a hollow component in the shape of a truncated cone, which is arranged inside the cooking chamber and allows two ways of cooking food. The truncated cone has a base with a diameter greater than the diameter of the top of the truncated cone; this component can operate between a standard operating condition and a tilted operating condition. In the standard operating condition, the base of the truncated cone is arranged at the top, while the top of the truncated cone is arranged at a lower height than the base ("funnel" arrangement); in this condition, the hollow component allows the indirect cooking of food. In the tilted operating condition, the hollow component is tilted 180° with respect to the standard operating condition and the base of the truncated cone is at the bottom, while the top of the truncated cone is at a higher height than the base ("volcano" arrangement); in this condition, the hollow component allows direct cooking of food.

In general, during the use of barbecues, food undergoing cooking releases cooking oils and fats, which drip onto the bottom and affect the cleaning of the lid. Basically, when using the barbecue, both the bottom and, where applicable, the lid are subject to getting dirty. In barbecues equipped with the hollow component in the shape of a truncated cone placed inside the cooking chamber, the component itself is subject to getting dirty when using the barbecue.

In addition, in charcoal barbecues the bottom has a hole through which ashes from the combustion of charcoal can pass; these ashes, passing through the hole, are collected by a container placed under the bottom of the barbecue. Because of the ashes, this container is also subject to getting dirty. A known solution to prevent cooking residues, oils and fats from dripping into the ash collection container (in charcoal barbecues) or from sedimenting on a barbecue surface below the grill where the food is placed (for gas barbecues) is to place a tray under an opening through which the above substances can pass.

As far as the bottom and the lid are concerned, to guarantee the cleaning of the barbecue and for hygienic reasons, after each use of the barbecue it is necessary to manually clean the bottom and, where necessary, the lid; in particular, it is necessary to clean at least the bottom, where most of the residues, oils and cooking fats are sedimented. Sometimes, for example after multiple uses of the barbecue, if you do not use the above mentioned tray, it is necessary to clean the ash collection container as well.

However, cleaning these components is not easy and is time-consuming.

The need to manually clean these barbecue components is sometimes one of the reasons why the barbecue is rarely used. In essence, having to clean these components manually is not an incentive for more frequent use of the barbecue and can adversely affect the choice to purchase a barbecue.

PURPOSES OF THE INVENTION

The purpose of this invention is therefore to solve at least one of the disadvantages and/or limitations of the previous solutions.

A first purpose of the present invention is to provide a lining for a hollow element of a barbecue that allows to exempt the user from the need to clean this hollow component of the barbecue after its use.

DETAILED DESCRIPTION

Lining

In the attached figures, with the numerical reference 1 , 1 ', 1 " a lining has been indicated overall. The lining 1 , 1 ', 1 " is of the removable type and is removably couplable to a respective hollow element 21 , 21 ', 21 " of a barbecue 50. The lining T, T, 1 " is basically an inner lining configured to be removably couplable at an inner surface of the respective hollow element 21 ', 21 ', 21 ". As you will see in more detail below, the hollow element of the barbecue 50 can be a bottom element 21 (bottom) configured to delimit a cooking chamber of the barbecue 50, a covering element 2T (lid) configured to superiorly delimit the cooking chamber or a ash collection container 21 ". In this regard, note that bottom elements 21 are shown in Figures 9A, 9B and 1 1 , covering elements 2T are shown in Figures 8A, 8B, 9A, 9B and 1 1 and an ash collection container 21 " is shown in Figures 9A, 9B and 12. As shown in the attached figures, the hollow element 21 ', 21 ', 21 " has a concavity 21 a and a perimeter edge 21 b delimiting perimetrically an access opening to the concavity 21 a. In the following, unless otherwise indicated, the hollow element will be referred to as concave element 21 , 21 ', 21 ".

The lining 1 , T, 1 " includes a body 2 having a plurality of sectors 3. Each sector 3 essentially defines a portion of body 2, such as a segment of body 2 (see Figures 1 A-1C, 2A-2B, 4A-4B, 6A-6B, 7, 8a-8B, 9A-9B and 12) or a circular crown of body 2 (see Figures 3A-3B and 5A-5C) or walls of body 2 (see Figures 10 and 1 1 ). Sectors 3 can be delimited by corrugation lines 3' or by bending or weakening lines 3”. Body 2 is configured to assume at least one rest and one coupling configuration. In the rest configuration, sectors 3 may be coupled with each other (see for example the embodiments of Figures 1 B, 4A and 7) or decoupled from each other (see for example the two exploded sectors in the embodiment of Figure 2A). In the coupling configuration, body 2 has a conformation obtained by orientation of sectors 3 such that the lining 1 , T, 1 " has a concavity and can be coupled to the respective concave element 21 , 21 ', 21 "; in this regard, see the embodiments in figures 1C, 2B, 3B, 5C, 6B, 9A-9B, 1 1 and 12. In the coupling configuration, body 2 has a concave shape defining a concavity 2a bounded by a perimeter edge 4 of body 2, which defines an access port 2c to concavity 2a. In order to allow an optimal coupling between lining 1 , T, 1 " and the respective concave element 21 , 21 ", 21 ", body 2 of lining 1 , T, 1 " in the coupling configuration may be countershaped or complementary to the conformation of the respective concave element 21 , 21 ', 21 " to which the lining 1 , T, 1 " is intended to be coupled and may have dimensions corresponding to the respective concave element 21 , 21 ', 21 ". Following the taking on of the coupling configuration, the body 2 can take on a gathered configuration, which will be detailed below and which allows easy transport and a small volume. Further details of the body and the orientation of the sectors in the rest and coupling configurations are described below with reference to the embodiments of the lining illustrated in the attached figures and their possible variants.

The body 2 of the lining 1 , 1 ', 1 " may be monolithic; embodiments in which the body 2 is monolithic are shown in Figures 1A-1 C, 3A-3B, 4A-4B, 5A-5C, 6A-6B, 7, 8A-8B, 9A-9B and 12. The monolithic body 2 has sectors 3 coupled together in both the rest and coupling configuration, which are distinguished by the reciprocal orientation assumed by sectors 3; in essence, sectors 3 of the monolithic body 2 develop seamlessly. The monolithic body 2 has a side wall 2b and at least one perimeter edge 4 delimiting, in the coupling configuration, the concavity (see, for example, figure 1 C). In the embodiments of the lining 1 , 1 ', 1 " that provide for a monolithic body 2, the rest configuration of body 2 can be a gathered configuration, in which body 2 has a volume which is smaller than its volume in the coupling configuration. For example, in the gathered configuration the body 2 may have sectors bent one on top of the other and at least partially overlapping each other; in this respect see, for example, figure 4A. Providing a body 2 that can take on a gathered configuration is particularly advantageous as it makes it possible to minimize the volume of body 2; in this way, i.e. by creating a compact format of the lining 1 , T, 1 ", it is possible to store the lining 1 , T, 1 " in a reduced volume format, consequently optimizing the transport of the lining and its supply and stacking the linings 1 , T, 1 " in gathered configuration on top of each other. In order to assume a configuration with an even smaller volume, body 2 of cover 1 of Figure 4A may be further bent at least once, e.g. along its longitudinal centreline or parallel to it. Providing a monolithic body 2 is particularly advantageous for a 1 , T, 1 " disposable lining which, after its use, is thrown away.

As an alternative to the monolithic body 2, the body 2 of the lining 1 , T, 1 " can have a plurality of sectors 3 couplable to each other. A body 2 presenting sectors 3 couplable to each other is of a modular type; embodiments of the linings 1 , T presenting a body 2 of modular type are illustrated in figures 2A-2B, 10 and 1 1. The coupling between sectors 3 of body 2 defines the side wall 2b of body 2. Sectors 3 of body 2 of the modular type can be decoupled from each other. Providing a modular type 2 body is particularly advantageous for a reusable type lining 1 , T, 1 ", whose sectors 3 can be decoupled from each other after use of the lining 1 , T, 1 " and can be stored, for example after washing them, in a limited space.

Embodiments of a lining 1 configured for lining a bottom element 21 of a barbecue 50 or a component arranged within a bottom element 21 of a barbecue 50 are now described.

In the embodiment of the lining 1 illustrated in Figures 1 B and 1C, the monolithic body 2 defines a concave shape with an access opening 2c and a passage 2d opposite the access opening 2c. The access opening 2c is delimited by the perimeter edge 4 and allows access to the concavity 2a. Passage 2d has a smaller passage section than a passage section of access port 2c and is configured, under conditions of use of lining 1 , to allow the passage of ash and air through it. The lining 1 shown in figure 1 C is configured to be removably coupled to a bottom element 21 of a barbecue 50. For this purpose, body 2 has a first series of through openings 2e arranged at a height and a second series of through openings 2f arranged at a higher height. In conditions of use of lining 1 , the first and second series of through openings 2e, 2f are configured to allow the positioning of a respective grill at the respective height at the concavity 2a defined by the side wall 2b of the body. In particular, each opening through 2e, 2f is configured to be crossed by a respective bracket for grill support configured to support a grill (see the cross-section in Figure 9B). The lining 1 is configured to pass between the rest configuration and the coupling configuration for unfolding these sectors 3. For example, the lining 1 can be supplied in the collection configuration (compact format); from this collection configuration, the user can unfold sectors 3 at least partially folded to obtain the concave conformation shown in Figure 1 C.

Figure 3B illustrates an additional embodiment of a lining 1 having a monolithic body 2. The lining in figure 3B is in coupling configuration and has a concavity 2a with a truncated cone shape; this lining 1 is configured to be coupled to a truncated cone component of a barbecue 50 placed inside the concavity 21 a of a bottom element 21 of the barbecue 50. The lining 1 in figure 3B is particularly suitable for use with 50 gas barbecues equipped with the truncated cone shaped component (concave barbecue element) described above with reference to known barbecues. In particular, in order to allow an optimal coupling between the truncated cone component and body 2 of lining 1 , body 2 in coupling configuration can be at least partially countershaped to the conformation of the truncated cone component of the barbecue 50 to which the lining is intended to be coupled. The body 2 may also have dimensions corresponding to the truncated cone component of the barbecue 50 to which the lining is intended to be coupled.

A further embodiment illustrating a lining 1 having monolithic body 2 for a bottom element 21 is shown in figure 4A, in which the body 2 is represented in a possible gathered configuration. In the gathered configuration, the sectors 3 are folded to form a series of overlapping zones 5, each of which has portions of adjacent sectors 3 overlapping or facing each other; in this regard, see the detail in Figure 4A illustrating portions of sectors 3 facing each other at overlapping zones 5. Body 2 with a series of overlapping zones 5 can be folded, in the gathered configuration, substantially like an accordion or a fan; in this respect, figure 4A shows a body folded like an accordion. This body 2 can pass from the gathered configuration to the coupling configuration by unfolding portions of the body 2. In this regard, see figure 4B illustrating a body 2 placed inside the concavity of the bottom element 21 of a barbecue 50, in which the arrows A1 indicate possible directions along which body 2 can be moved to unfold sectors 3 around an axis of revolution and allow it to assume the coupling configuration. Subsequently, as will be seen below with regard to the process for engaging a lining 1 , T, 1 " to the respective concave element 21 , 21 ', 21 ", in order to couple lining 1 to the bottom element 21 , the perimeter edge 4 of body 2 may be folded over to the perimeter edge 21 b of the bottom element 21.

Figures 2A and 2B show an embodiment of the lining 1 , for a bottom elements 21 , equipped with a modular body 2. In the rest configuration, sectors 3 of the modular body 2 are separated from each other, while in the coupling configuration, sectors 3 of the modular body 2 are coupled together. The modular body 2 is configured to pass from the rest configuration to the coupling configuration for sector 3 coupling. As illustrated in Figures 2A and 2B, each sector 3 is concave and has an elongated conformation developing between a first end 3a and a second end 3b mutually opposed. Each sector 3 can be tapered and narrowed from the first end 3a to the second end 3b. For example, Figures 2A and 2B show tapered sectors 3 with a substantially "sliced" shape; Flowever, further conformations of sectors 3 are possible, such as an annular conformation according to which the sectors have different diameters and can be superimposed on each other, starting from the sector with a smaller diameter, which can be placed around and near a passage of the bottom element 21 for the passage of air and ash, until the sector with a larger diameter overlaps, which can be placed at or near the perimeter edge of the bottom element. Each sector 3 has a portion of the perimeter edge at the first end. Each sector also has longitudinal edges 3c, 3d developing between the first end 3a and the second end 3b. The longitudinal edges 3c, 3d of adjacent sectors 3 are configured to couple each other to form the coupling configuration of body 2; in this respect see the detail of figure 2B illustrating longitudinal edges 3c, 3d of adjacent sectors overlapped and coupled together. The detail in Figure 2B shows, by way of example, a sector 3 whose longitudinal edge 3c is fitted with a recess and an adjacent sector 3 whose longitudinal edge 3d is fitted with a protrusion arranged within the recess in such a way as to permit coupling between these adjacent sectors 3; however, further ways of coupling between adjacent sectors 3 and in particular between their respective edges 3c, 3d adjacent may be provided, such as snap coupling, interlocking or by means of dedicated fasteners. The transition of the body 2 from the rest configuration to the coupling configuration is made by coupling sectors 3; vice versa, the transition of the body 2 from the coupling configuration to the rest configuration is carried out by decoupling the sectors 3. As previously described with reference to the embodiment of figures 1A-1 C, in order to be removably coupled to the bottom element 21 of a barbecue 50, body 2 of lining 1 of the embodiment illustrated in figures 2A-2B is equipped with a first series of through openings 2e arranged at a height and a second series of through openings 2f arranged at a higher height. Optionally, the second end 3b of sectors 3 can be configured to co-operate with an abutment (not shown in the attached figures), which can be provided by the bottom element 21 , to allow for the correct positioning of the body 2 of the lining 1 with respect to the bottom element 21. Body 2 of the modular type can take on the gathered configuration, which can be achieved by superimposing sectors 3 in such a way that the respective concavities of superimposed sectors 3 are facing each other; in this way, it is possible to optimally stack the sectors so as to minimize the volume of the body 2. A further embodiment of a lining 1 , for a bottom element 21 , equipped with a modular body 2 is shown in figure 10. The body 2 of the modular type illustrated therein is equipped with sectors 3 defining the respective walls of the lining 1 couplable to each other. The lining 1 shown in figure 10 is configured to be coupled to a parallelepiped shaped bottom element 21 ; such a bottom element 21 can be a gas barbecue. Figure 1 1 shows another lining 1 , for a bottom element 21 , equipped with a modular body 2; body 2 is illustrated in the coupling configuration in which sectors 3 are coupled together.

Embodiments of a lining T configured for lining a covering element 2T of a barbecue 50 are now described.

In the embodiment of the lining T in Figure 5A, the body 2 is monolithic and has a plurality of folding lines 3"; in a variant, these lines may be weakening lines 3". The folding or weakening lines 3" are concentric and delimit between them 3 concentric annular sectors. In the embodiment shown in figure 5C, the folding or weakening lines 3" are configured to allow the body to move from the rest configuration (see figure 5A) to the coupling configuration by plastic deformation of the body 2 as part of the process for realizing the lining T described below. Basically, the folding or weakening lines 3” are configured to allow the transition from the T rest configuration shown in Figures 5A and 5B to the coupling configuration shown in Figure 5C by applying a force transverse to the sheet material element in Figure 5A, for example, by applying a force along at least one of the directions shown by the A2 arrows in Figure 5C. This force allows the body 2 to be plastically deformed. The plastic deformation of the body allows the formation of concavity 2a and determines the formation of 3' corrugation lines; in this regard, see figure 5C, illustrating concentric 3' corrugation lines. Body 2 may optionally provide at least one through opening, which may be designed to allow at least one functional element of the covering element 21 ' or air to pass through (through opening not shown in Figures 5A-5C); in this respect, see the embodiments in Figures 6A-6B and 7.

The body 2 of the lining T illustrated in Figures 6A-6B, which is of monolithic type, has a plurality of through openings 6', 6", 6"' located at a top 2g (defined with reference to the conditions of use of the lining T, in which it is reversed with respect to the orientation illustrated in Figures 6B and 7) of the lining T opposite the access opening 2c; this top, with the exception of these through openings 6', 6", 6"', is a substantially closed top. This body 2 has a first through opening 6' intended to be crossed, under conditions of use of the lining T, by an extreme portion of a barbecue thermometer, second through opening 6” intended to allow air to pass through it, in conditions of use of the lining T where they face the respective air passage openings of an air flow regulation device 22, and third through openings 6'” designed to allow the passage of one end, e.g. a head end, of respective threaded elements 25 configured to constrain a handle 24 of the covering element 2T. The embodiment of figures 6A-6B provides one first through opening 6', four second through openings 6" and two third through openings 6'”; in alternative embodiments, these through openings 6', 6', 6"' can be in different numbers, according to the specific characteristics and functional needs (for example related to the passage of air or the housing of specific functional elements) of the covering element 2T. Furthermore, the through openings 6', 6", 6"' have been represented as having a substantially circular shape; it is understood that the shape of the through openings 6', 6", 6"' may vary according to the shape of the respective air passage openings and the respective functional elements of the covering element 2T with which these through openings are configured to cooperate. In other embodiments, one or more recesses may be provided instead of at least one or each of the third through openings 6"': the recesses allow to house the end of the respective threaded element 25 without being crossed by it. In possible embodiments, instead of at least one through opening 6', 6", 6"' or each through opening 6', 6", 6"' of the type just described, body 2 can provide a respective weakened portion, e.g. of removable type, configured to define at least one through opening 6', 6", 6"'; each weakened portion can be operated, e.g. removed, by a user of the lining T prior to use of the lining T itself to form the respective through opening 6', 6", 6"'. In possible embodiments, through openings 6"' or recesses for ends of threaded elements 25 can be omitted. The body 2 of the lining T shown in figures 6A-6B allows the body to pass from the rest configuration to the coupling configuration by plastic deformation of the body 2; in this regard, figure 6A illustrates the rest configuration of the body (planar conformation sheet material element), and Figure 6B illustrates the coupling configuration, obtained by plastic deformation of the body 2 (concave conformation sheet material element). The plastic deformation of body 2, which determines the transition of body 2 from a planar to a concave conformation, determines the formation of the corrugation lines 3' delimiting sectors 3. Figure 7 illustrates an embodiment of the lining 1 ' for a covering element 21 ' whose body 2 is monolithic and is made from a monolithic element in sheet 8 material with an elongated conformation, which can be of the type shown in figure 1 A, but without through-holes. Figure 7 illustrates the transition of body 2 between the rest and coupling configuration, which involves approaching opposing ends of the sheet material element to form concavity 2a.

An embodiment of the lining 1' for a covering element 21 ' of a barbecue 50 equipped with a modular body is shown in figure 10. The body 2 of the modular type illustrated here is equipped with sectors 3 defining the respective walls of the lining T couplable to each other. Figure 1 1 shows another lining T for a covering element 2T with a modular body 2, wherein the body 2 is shown in the coupling configuration in which sectors 3 are assembled together.

Embodiments of a lining 1” configured for covering an ash collection container 21 " of a barbecue 50 are now described. A lining 1” for a ash collection container 21 " is shown, in coupling configuration, in figure 12, in exploded view of the ash collection container 21” to which it is configured to be coupled; the arrow A3 shown therein indicates the direction along which body 2 of the lining 1” can be moved to allow its engagement to the ash collection container 21”. The body 2 of the lining 1” shown in figure 12 is of monolithic type and, therefore, has coupled sectors 3 both in the rest and in the coupling configuration. The monolithic body 2 is configured to pass through plastic deformation between the rest configuration and the coupling configuration. As shown in Figure 12, the sectors can then be delimited by 3' corrugation lines. In a possible embodiment, the body 2 of the lining 1 " can be configured to pass between the rest configuration and the coupling configuration by unfolding the sectors 3. In another possible embodiment, the body 2 of the lining 1 " can be of modular type and can have sectors couplable to and decouplable from each other in order to pass from the rest configuration to the coupling configuration and from the coupling configuration to the rest configuration respectively by coupling and decoupling the sectors according to what previously described.

The following is a description of the possible constraint elements for the coupling and relative ways of coupling the lining to the respective concave element 21 , 21 ', 21 ", which can be used for each lining 1 , T, 1 " previously described. In order to allow a stable coupling to the respective concave element 21 , 21 ', 21 ", the lining 1 , T, 1 " includes at least one constraint element. The constraint element may include the perimeter edge 4 of body 2, which acts as the constraint edge 4' (see Figures 8B and 9B). This 4' binding edge is configured to assume at least a first configuration in which it does not bind the lining 1 , T, 1 " to the respective hollow element 21 , 21 ', 21 " of a barbecue 50 and a second configuration in which it binds the lining 1 , T, 1 " to the respective hollow element 21 , 21 ', 21 ". The transition between the first configuration and the second configuration can be made by folding the constraint edge 4', as shown in Figure 9B, where the dashed constraint edge represents the constraint edge 4' in the first configuration and the continuous stroke constraint edge represents the constraint edge 4' in the second configuration.

In addition to or as an alternative to the constraining edge 4', the lining 1 , T, 1 " may also include, as a constraint element, at least a clip 7; see Figures 8A and 8B. The clip 7 can be removably couplable to the body 2 of the lining 1 , T, 1 " at the perimeter edge 4 and is configured to assume at least one disengagement configuration and one engagement configuration. In the disengagement configuration, the clip 7 is disengaged from the perimeter edge 4, while in the engagement configuration the clip 7 is engaged at the perimeter edge. Under the conditions of use of the lining, clip 7 binds the body 2 to the respective concave element 21 , 21 ', 21 " in the binding configuration; see in particular the detail in Figure 8B, illustrating a binding clip 7 the lining to the respective covering element 21 '. Clip 7 is configured to pass elastically between the disengagement configuration and the engagement configuration. For this purpose, the clip 7 can be made of elastically deformable material. Optionally, clip 7 is made of metal material. The clip 7 defines an inner constraint space configured to accommodate at least a portion of the perimeter edge 4. From a structural point of view, the clip 7 comprises a first flap 7a, a second flap 7b and a connecting portion 7c. The connecting portion 7c is placed between, and connects, the first flap 7a and the second flap 7b, which are facing each other and define, in interposition with each other, the inner constraint space of the clip 7 in which a portion of the perimeter edge 4 is intended to be placed in the engagement configuration of the clip 7. As illustrated in detail in Figure 8B, the first flap 7a and the second flap 7b emerge from the same part of the connecting portion 7c. As illustrated in detail in Figure 8B, in the engagement configuration the first flap 7a can be placed at concavity 2a, while the second flap 7b can be placed outside concavity 2a, near an external surface of the concave element 21 , 21 ', 21 ". In the engagement configuration, both the first and second flap 7a, 7b may be in contact with a respective portion of the perimeter edge 4a. The first flap 7a and the second flap 7b may be at least partially countershaped or shaped to correspond to at least a portion of a 21 b perimeter edge of the concave element 21 , 21 ', 21 ". As illustrated in detail in figure 8B, body 2 of lining 1 , and in particular its bound perimeter edge, can be bound and interposed between the first flap 7a and the perimeter edge 21 b of the concave element 21 , 21 ', 21 ". As shown in Figure 8A and Figure 8B, the lining T may include a plurality of 7 clips.

As shown in figure 8B with reference to a lining T for a covering element 21 ', in the embodiment of the lining 1 , T, 1 " that provides for both the constraint edge 4' and at least one clip 7 as constraint elements, the clip 7 is configured to constrain the constraint edge 4' previously folded on the perimeter 21 b of the concave element 21 , 21 ', 21 " to the respective concave element 21 , 21 ', 21 ".

In terms of materials, the body 2 of each lining 1 , 1 ', 1 " of the type described above is preferably made of metallic material. Providing metal material allows the body to resist without damage to the temperatures that can develop inside the concave element to which the lining 1 , T, 1 " can be coupled and in particular inside the cooking chamber or in the ash collection container 21”. In possible variants, the body 2 can be made of an alternative material to the metal material and suitable to resist without damage to the above mentioned temperatures. In the attached figures, the body 2 is made of metal sheet.

By way of example, it should be noted that, in the embodiments wherein the body 2 of the lining 1 , T, 1 " is monolithic, the body 2 may have a thickness between 0.06 mm and 0.4 mm, in particular between 0.08 mm and 0.2 mm. This body 2 can be made of aluminium. Providing a body 2 thickness within this range or similar ranges allows body 2 to have the rigidity (to allow a stable coupling configuration) and at the same time the necessary flexibility (to take on the gathered configuration) for its disposable use; in essence, a body 2 of this thickness is configured to pass easily from the gathered configuration to the coupling configuration and to be folded or crumpled, after using the lining 1 , 1 ', 1 ", in order to throw away the lining 1 , 1 ', 1 " itself. This thickness ensures that the lining 1 , 1 1 " retains its shape and dimensions when no mechanical force is applied.

The material of body 2 is preferably impermeable, e.g. impermeable to oils, cooking grease and/or cooking residues. The body 2 may be made of fireproof material and, in addition or alternatively, non-flammable material. With regard to the embodiments in which the body 2 of the lining 1 , 1 ', 1 " is of the modular type, it is reported by way of example that body 2 (and in particular each sector 3 of body 2) can have a thickness between 0.08 mm and 1.5 mm, in particular between 0.1 mm and 1 mm. This body 2 can be made of stainless steel or carbon steel (unalloyed steel); the steel can be galvanized and enamelled. Providing a thickness of body 2 within this range or similar intervals allows body 2 to have the rigidity necessary for its use and, optionally, for its washing. In particular, providing for such materials allows the lining 1 , T, 1 " to be washed, for example in a dishwasher, after use without damage. In alternative embodiments, the lining 1 , T, 1 " of reusable type may be in alternative materials to those described above, which allow at the same time to wash the body 2 of the lining 1 , T, 1 ", for example in dishwashers, without damaging it and to resist the high temperatures that exist, under conditions of use of the lining 1 , T, 1 ", inside the concave element 21 , 21 ', 21 " to which the lining 1 , T, 1 " is coupled.

As regards the lining 1” for an ash collection container 21”, it may have a diameter such that the lining can be coupled to an ash collection container 21” with a circular cross-section; this diameter may, for example, be between 5 cm and 30 cm. The dimensions of body 2 of the lining 1 , T, 1 " may vary according to the characteristic dimensions of the concave elements 21 , 21 ', 21 " of commercially available barbecues 50.

The lining 1 , T, 1 " according to this invention can be of a dedicated type (ad hoc lining), i.e. it can be designed and sized according to the characteristic dimensions of the respective concave elements 21 , 21 ', 21 " of a specific commercially available model of barbecue 50.

Alternatively, the lining 1 , T, 1 " according to this invention can be of generic type (standard lining), i.e. it can be designed and sized in such a way as to present a body 2 adaptable to the characteristic dimensions of the respective concave elements 21 , 21 ', 21 " of a plurality of commercially available barbecue 50 models. With regard to the monolithic body 2, the adaptability of body 2 can be achieved, for example, by providing for removable portions or sectors 3, such as tear portions or sectors 3, which can be removed or torn to dimensionally adapt body 2 of the lining 1 , 1 ', 1 " to the respective concave elements 21 , 21 ', 21 " of the model of barbecue 50 with which the lining 1 , 1 ', 1 " is used. With regard to the modular body 2, the adaptability of body 2 can be achieved, for example, by providing for a number of sectors 3 of different sizes, which can be selected and coupled to dimensionally adapt body 2 of the lining 1 , 1 ', 1 " to the respective concave elements 21 , 21 ', 21 " of the model of barbecue 50 with which the lining 1 , 1 ', 1 " is used .

The covering element 2T can be equipped with an air flow regulation device 22 configured to regulate an air flow through one or more air passages 22a. The covering element 2T can also be equipped with a thermometer 23' configured to detect a temperature inside the cooking chamber of the barbecue 50 when in use. The covering element 2T may also be fitted with a handle 24 which is secured by at least one threaded element 25, which may protrude from the inner surface of the covering element 2T.

The barbecue assembly 100 includes at least a lining 1 , T, 1 " of the type previously described configured to be removably coupled to one of the above mentioned concave elements 21 , 21 ', 21 ". The lining 1 , T, 1 " is basically an accessory of the barbecue 50. In particular, the barbecue assembly 100 may include a lining 1 for the bottom element 21 and a lining T for the covering element 2T (a kit 10); see Figures 9A, 9B and 1 1. In an embodiment, the bottom element 21 and the covering element 2T may have a substantially hemispherical shape and the respective coverings have a substantially hemispherical shape at least partially countershaped to the shape of the respective concave element 21 , 21 ', 21 " to be covered (see Figures 9A and 9B).

In this embodiment, the barbecue 50 can be gas-fired (see figure 11 ).

Process for realizing the lining The present invention concerns also a process for realizing the previously described lining 1 1 1 The process involves providing a sheet material element 8, such as a metal sheet. The process may, optionally, provide to define, on the sheet material element 8, a plurality of sectors 3 of the type previously described. The sheet material element 8 is preferably monolithic and has a substantially planar shape. The sheet material element 8 is configured to form the body 2 of the lining 1 ; in some embodiments, particularly those with a monolithic body, the sheet material element 8 may, if suitably shaped, substantially coincide with the body 2 of the lining 1. In this regard, see the attached figures 1A, 3A, 5A and 6A illustrating respective shaped sheet material elements 8. In the case of monolithic sheet material element 8 intended to form the body 2 of a lining 1 for a bottom element 21 (see figure 1A), the sheet material element 8 may have one or more sets of through openings 2e, 2f configured to allow, in accordance with what has been described above, the passage of brackets 54, 55 for grill support. In the case of a monolithic sheet material element 8 intended to form a lining T for a covering element 2T (see figure 6A), the sheet material element 8 may have 6', 6", 6"' through-holes of the type previously described configured to allow the passage of functional elements or air.

The following is a description of embodiments of the process that envisages the realization of a lining 1 , T, 1 " with a monolithic body 2. The process involves the preparation of a monolithic element in sheet 8 material. In such embodiments, the definition of sectors can be achieved by plastic deformation of the monolithic element in sheet 8 material. The sheet material element 8 may include, at one end of the element, an edge configured to define the perimeter edge 4 which, in the coupling configuration, delimits the access port 2c of body 2 (see Figures 1A-1 C). Similarly, the sheet material element 8 may include, at the opposite end, an edge configured to define the perimeter edge 4 which, in the coupling configuration, delimits the passage 2d of the lining body (see Figures 1A-1 C).

In some embodiments, the monolithic element in sheet 8 material may have an elongated conformation defined along a substantially straight or curvilinear path and develop between opposing ends 8a, 8b. The path along which the sheet material element develops can be arched (see Figure 1 A) or circular (see Figure 3A). In these embodiments, the process involves approaching the opposite ends 8a, 8b; this step is illustrated in Figures 1 B and 7. The process provides, after approaching the opposite ends 8a, 8b, to engage the opposite ends 8a, 8b to form the concavity 2a of body 2 of the lining 1 , T, 1 examples of linings 1 obtained in this way are shown in figure 1 C and 3B. The realization of the lining 1 , T can therefore provide to reach the coupling configuration of the sectors 3 presenting the opposite ends 8a, 8b (see figure 1 B). The coupling between sectors 3 makes it possible to form at least the access opening 2c (both for lining 1 , T for bottom elements 21 and covering elements 2T respectively) or both the access opening 2c and the passage 2d opposite it (for lining 1 for bottom elements 21 ; see figure 1 B).

In another embodiment, the monolithic element in sheet 8 material may have a circular shape; see figure 5A. The process involves making folding or weakening lines 3” on the sheet material element 8; the folding or weakening lines 3” delimit sectors 3. In the embodiment shown in Figure 5A, the bending or weakening lines 3" realized are concentric weakening lines delimiting 3 concentric sectors. The folding or weakening lines 3" can be made by plastic deformation of the sheet material element 8, e.g. by impression of the sheet material element 8. After making the folding or weakening lines 3", the process also involves forming the concavity 2a of the body 2 by moving at least one central portion of the sheet material element 8 orthogonally to a storage plane of the sheet material element 8. The formation of the concavity 2a of the body 2 is made by plastic deformation of the sheet material element 8. As schematically illustrated in figure 5C, this plastic deformation can be achieved by drawing or calendering the element in sheet 8 material, which is preferably made of metal sheet. Drawing can be carried out by interposing the sheet material element 8 between a die or mould with a cavity of the shape corresponding to the final conformation to be obtained (e.g. hemispherical or parallelepiped conformation) and a punch; subsequently, the punch forces the sheet material element 8 into the cavity of the die or mould in such a way that it takes on the desired conformation of the body of the lining 1 , 1 ', 1

Once sectors 3 have been defined, the process may involve bending at least one between body 2 and sectors 3 in such a way that body 2 is set up in a gathered configuration. The step of bending body 2 may involve overlapping sectors 3, so as to minimize the volume of the body 2. The step of bending sectors 3 can involve forming a series of overlapping zones 5 between adjacent sectors 3 and can be achieved by bending the body

2 like an accordion (see figure 4A).

The following is a description of embodiments of the process that envisages the realization of a lining 1 , 1 ', 1 " equipped with a modular body 2. In such embodiments, the definition of sectors 3 can be achieved by providing at least one monolithic element in sheet 8 material and dissecting it in such a way as to obtain a plurality of sectors 3. Alternatively, the definition of sectors 3 may provide for the direct provision of a body 2 equipped with separate and couplable sectors 3. The first end 3a of each sector 3 may include an edge configured to define a portion of the perimeter edge 4 that, in the coupling configuration, delimits the access port 2c of body 2 (see Figures 2A and 2B). Similarly, the second end 3b of each sector 3 may include an edge configured to define a portion of the perimeter edge that, in the coupling configuration, delimits the passage 2d of the lining body (see Figures 2A and 2B).

The process may involve making, on some sectors of the body, one or more through openings configured to allow, in accordance with what previously described, the passage of the brackets 54, 55 for grill support. In the configuration where sectors 3 are decoupled from each other, body 2 is in the rest configuration. Once sectors

3 have been defined, the process may provide for the sectors to be superimposed in such a way that body 2 is arranged in a gathered configuration.

Process for engaging the lining to a hollow element of a barbecue

The invention relates also to a process to bind a lining 1 , 1 ', 1 " of the type previously described to a hollow element 21 , 21’, 21” of a barbecue 50, which will be referred to below as a concave element 21 , 21 ', 21 ". This process can be carried out by a user of lining 1 , T, 1 ", e.g. on the basis of instructions associated with lining 1 , T, 1 ", which can be indicated on, or inside, a package or packaging containing the lining 1 or the kit 10. The process includes providing at least a lining 1 , T, 1 " of the type previously described and coupling the lining 1 , T, 1 " to a respective concave element 21 , 21 ', 21 ". The lining 1 , T, 1 " can be provided or supplied with body 2 in the rest configuration. In particular, the lining 1 , T, 1 " can be provided or supplied in the gathered configuration, from which the user can unfold the body 2 to reach the coupling configuration. For example, the body 2 can be provided or supplied in the gathered configuration of figure 4A, or in a further folded configuration, and can be unfolded by the user for coupling to the concave element 21 , 21 ", 21 ", as shown schematically in figure 4B using the arrows A1 .

In the embodiments that provide a lining 1 , 1 ', 1 " equipped with a modular body 2, in order to provide the lining 1 , 1 ', 1 " in the coupling configuration the process may provide coupling the sectors 3 to define the coupling configuration of the body 2 of the lining 1 , 1 ', 1 ". The coupling can be realized by placing side by side and engaging the sectors 3 to define a concavity 2a of the body 2, for example a concavity 2a shaped like a hemisphere or a truncated cone or parallelepiped. The step of engaging adjacent sectors 3 includes at least partially overlapping longitudinal edges 3c, 3d of at least two adjacent sectors 3; see detail in Figure 2B. The step of engaging adjacent sectors 3 may provide for a protrusion of a longitudinal edge 3d within a recess of a longitudinal edge 3c of adjacent sector 3.

If the lining 1 , T, 1 " is of standard type, the process may provide to adapt the body 2 to the respective concave element 21 , 21 ', 21 " to which it is intended to be engaged in accordance with what previously described.

After the preparation of body 2 in the coupling configuration, in order to engage the lining 1 , T, 1 " to the respective concave element 21 , 21 ', 21 ", the process may provide to fold at least a portion of the perimeter edge 4 of body 2 on the perimeter edge 21 b of the concave element 21 , 21 ', 21 "; in this regard, see figure 9B, in which the perimeter edge 4 of body 2 acts as the constraining edge 4'.

As an alternative to or in addition to the engagement of the lining 1 , T, 1 " to the concave element 21 , 21 ', 21 " by means of the binding edge 4', the process may provide to constrain the lining 1 , T, 1 " to the concave element 21 , 21 ', 21 " of a barbecue 50 by the application of at least one clip 7. The clip 7 can be applied astride the perimeter edge 4 of body 2. In particular, the process may provide to bind the lining 1 , T, 1 " to the concave element 21 , 21 ', 21 " by the application of a plurality of clips 7, which may be engaged, at a certain distance from each other, to respective portions of the perimeter edge 4 of the body 2. For example, clips 7 can be applied in such a way that they are angularly offset from each other.

If the barbecue 50 has one or more grilles 52, 53, prior to coupling the lining 1 to the respective bottom element 21 of the barbecue 50, the process may involve removing one or more grilles 52, 53 from the bottom element 21 (see figure 9A and figure 1 1 where the grilles 52, 53 are illustrated in exploded for a charcoal-burning barbecue 50 and a gas-burning barbecue 50 respectively), to engage lining 1 to the bottom element 21 and, after the engagement of the lining 1 , to engage grill 52 or grills 52, 53 to the bottom element 21 of barbecue 50. The engagement of the lining 1 to the bottom element 21 is carried out in such a way that one or more series of through openings 2e, 2f of body 2 of lining 1 are crossed by the respective brackets 54, 55 for grill support; in this way, each grill 52, 53 can be engaged, under conditions of use of the lining 1 , to the respective brackets 54, 55 for grill support. Figures 9A and 9B show an embodiment of a charcoal barbecue 50 equipped with two grills 52, 53, for which it is necessary to implement this process for the engagement of the lining 1 which involves the removal of the grills 52, 53. Figure 1 1 shows an embodiment of a gas barbecue 50 equipped with a 52 grill, for which it is necessary to implement this process for the engagement of the lining 1 that provides for the removal of the grill 52. As an alternative to through openings 2e, 2f, respective recesses can be provided configured to house these brackets 54, 55 for grill support and to provide a stop to allow the support of grilles 52, 53.

As regards the engagement of the lining 1 ' to a covering element 21 ', the process may provide for the engagement of the lining 1 ' to the covering element 21 ' in such a way that the through openings 6', 6", 6'" are crossed by the respective functional elements (end of thermometer 23, threaded elements 25) or facing the respective air passage openings 22a of the air flow regulation device 22 in accordance with what has been previously described.

Use of the lining

The invention also concerns the use of at least one lining 1 , T, 1 " of the type described above. After the engagement of the lining 1 , T, 1 " to the respective concave element 21 , 21 ', 21 ", the use of the lining 1 , T, 1 " may take place. The use of the lining 1 , T, 1 " is intended to preserve the condition of a concave element 21 , 21 ', 21 " of a barbecue 50. In particular, the use of the lining 1 , T, 1 " is aimed at preserving a cleanliness condition of an internal surface, delimiting the cavity 21 a, of a concave element 21 , 21 ', 21 " of a barbecue 50. When the lining 1 , T, 1 " is used, the lining 1 , T, 1 " is removably coupled to the respective concave element 21 , 21 ', 21 ". With regard to the lining 1 for the bottom element 21 , at the end of the use of the lining 1 , one or more grills 52, 53 may be disengaged from the bottom element 21 and the lining 1 may be disengaged from the bottom element 21.

In the embodiments with a disposable lining 1 , T, 1 ", at the end of use, after having disengaged the lining 1 , T, 1 " from the respective concave element 21 , 21 ', 21 " the lining 1 , T, 1 " can be thrown away.

In the embodiments with a 1 , T, 1 " reusable lining, at the end of use, after having removed the lining 1 , T, 1 " from the respective concave element 21 , 21 ', 21 ", the lining 1 , T, 1 " can be washed or cleaned in another way and can be stored for possible subsequent use.

ADVANTAGES OF THE INVENTION

The invention advantageously provides a lining 1 , T, 1 " on which oils, fats and/or other cooking residues or ashes are deposited under the conditions of use of the barbecue 50, preventing them from dirtying the concave element 21 , 21 ', 21 " lined by the lining 1 , T, 1 " and from encrusting on its internal surface.

The present invention therefore makes it possible to preserve the cleanliness of a concave element 21 , 21 ', 21 " of a barbecue 50 to which the lining 1 , T, 1 " is coupled.

The invention, by exempting the user of the barbecue 50 from the need to clean the bottom element 21 and/or the covering element 2T and/or the ash collection container 21”, allows for a more pleasant and less burdensome (compared to using the barbecue without covering) experience in terms of managing the barbecue 50 after it has been used. A further advantage of the invention, consequent to the one just described, is to encourage the use of the barbecue 50. A further advantage of the invention is that it considerably reduces the cleaning time of the concave element 21, 21', 21" of the barbecue 50; in essence, the cleaning time of the barbecue 50, thanks to the invention, consists of the time required to remove the lining 1, 1', 1" from the respective concave element 21, 21', 21".

In addition, the invention provides a lining 1, 1', 1" that can be removably couplable to the respective concave element 21, 21', 21" in a simple and effective way.

The present invention also provides a process for making the lining 1, T, 1" in such a way as to minimize or eliminate material waste.

The advantages described above are shared by the lining 1, T, 1", by the kit 10, by the assembly 30, by the barbecue assembly 100, by the process for realizing the lining 1, T, 1", by the process for engaging the lining 1, T, 1" to a hollow element 21, 21" of a barbecue 50 and the use of the lining 1, T, 1" in accordance with this invention.
