The home appliance holding device comprises a holding element housing with a plurality of recesses positioned vertically on top of each other, into which a holding element that supports the cooking product support unit is introduced.

The task of the invention is, in particular, to make available a generic household appliance holding device with advantageously high convenience of use. According to the invention, the task is solved by the characterizing features of claim 1, while advantageous embodiments and improvements of the invention can be extracted from the secondary claims.

The invention is based on a home appliance clamping device for a height adjustment of a support unit in a usable space with at least one clamping element and at least one clamping element housing.

It is proposed that the clamping element housing comprises at least one guide which, for height adjustment, conducts, at least partially, vertically the clamping element in at least one assembled state. By "height adjustment" of the support unit, a process of at least essential modification of an installation height of the support unit in the usable space in at least one space must be understood in particular. operational status and / or at least one operating status. By "at least essential" modification of the installation height, it is necessary to understand, in particular, a relative modification of the installation height in the usable space by at least 10%, especially at least the 20%, preferably at least 30% and, especially advantageously, of at least 40%. By "assembled state", in this context it is to be understood, in particular, a state of a domestic appliance presenting the domestic appliance holding device in which

there is a coupling of the clamping element with the clamping element housing. By "operational status",

it is to be understood, in particular, an assembled state of the domestic appliance in which the domestic appliance is ready for proper operation, especially a cooling operation or a cleaning operation and / or, preferably, a heating operation. With the presence of the operating state, the clamping element is specially held in a clamping point of the guide. By "operating state", it is to be understood, in particular, a correct operation, especially a cooling operation or a cleaning operation and / or, preferably, a heating operation, of the domestic appliance.

By "support unit", in this context it is to be understood, in particular, a unit that, in at least one state

mounted, is intended to hold a product, especially a refrigeration product or a cleaning product or, preferably, a cooking product, and / or to support a support element for a product, especially a shelf , preferably a shelf of a refrigeration and / or freezer apparatus, or a tableware holder, preferably, a tableware holder of a dishwasher, or a cooking product holder, in particular a cooking rack, a baking tray cooking, or a fat collection tray, within the usable space. By "intended", here, and hereafter, it is to be understood, in particular, configured and / or provided specifically. The support unit may in particular comprise at least one support and / or guide rail for the support element, preferably a support and / or guide rail for a cooking product support, in particular a grill cooking, a cooking pan, or a fat collection tray. However, the support unit preferably comprises at least one telescopic slide for the support element, preferably a telescopic slide for a cooking product holder, in particular a cooking grill, a cooking tray, or a tray of fat collection. Likewise, the support unit can be made especially as a shelf, preferably shelf of a refrigeration and / or freezer apparatus, as a tableware support, in particular, tableware support of a dishwasher, or as a cooking product holder , especially, cooking grill, cooking pan, or grease collection tray. Preferably, the support unit is composed of a metal, at least essentially stainless, in particular, of fine steel or chromed steel, at least partially and, especially advantageously, in large

part. By "large part", in this context it is to be understood, in particular, in a percentage by weight of at least the

70%, in particular, of at least 80%, preferably, of at least 90% and, especially advantageously, of at least 95%. Alternatively or additionally, the support unit may be especially enameled.

By "usable space", here, and hereafter, it is to be understood, in particular, a space that is intended for, in at least one state of operation of the domestic appliance, to house a product, in particular, a refrigeration product, a cleaning product or, preferably, a cooking product. The usable space can be specially configured as a cooling and / or freezing space, as a cleaning space or, of

preferred way, as cooking space. By "clamping element", it must be understood, in particular, an element

that, in at least one operating state of the domestic appliance, it is intended to hold the support unit in the usable space, especially also in interaction with other construction elements, preferably other fasteners. In the operating state, the clamping element especially absorbs at least an essential part of a force of the weight of the support unit. By "at least essential part" of the strength of the weight of the support unit, it is to be understood, in particular, at least 25%, so

preferably at least 40% and, especially advantageously, at least 50% of the strength of the weight of the support unit. In particular, the clamping element can be fixedly connected to the support unit, especially through a joint by direct or indirect welding, by riveting and / or by gluing or, preferably, in one piece, or in a manner separable again, especially through a threaded joint, by plug and / or by socket. By "in one piece", in this context it is to be understood, in particular, formed together, such as by manufacturing from a cast piece and / or by manufacturing in an injection procedure of one or more components.

By "holding of a clamping element", in this context it is especially necessary to understand a construction unit configured differently from the clamping element, which houses the clamping element and, preferably, supports it, in at least one state of operation of the domestic appliance. In the operating state, the clamping element housing especially absorbs at least a large part of a force of the weight of the clamping element. By "at least a large part" of the force of the weight of the fastener, it is to be understood, in particular, at least 80% and, preferably, at least 90% of the force of the weight of the element clamping and, especially advantageously, the strength of the total weight of the clamping element. Preferably, the clamping element housing is configured in one piece, and is composed of metal, especially at least partially and, preferably, at least in large part. For the fact that the accommodation

of fastening element is composed of "metal, at least in large part", it is understood, in particular, that the

Clamping element housing is composed of metal with a weight percentage of at least 60%, in particular of at least 70%, preferably of at least 80% and, especially advantageous of at least 90%.

By "guide", it is to be understood, in particular, a constructive element that drives the clamping element, at least, during height adjustment. The guide comprises at least one contact surface for a restriction of a freedom of movement of the clamping element, especially during height adjustment, where the contact surface and the clamping element are preferably directly adjacent to, at less, a mounted state. Preferably, the guide has at least two contact surfaces preferably opposite each other and, especially advantageously, at least essentially parallel to each other, which restrict both freedom of movement of the fastener on both sides, regardless of a clearance of the fastener in the guide, especially during height adjustment. Preferably, a distance of the contact surfaces parallel to each other corresponds, at least, essentially, with at least one dimension of the fastener, especially with a thickness of the fastener. Due to the fact that the distance of the surfaces

of parallel contact with each other corresponds "at least essentially" with the dimension of the clamping element,

it should be understood, in particular, that a relative deviation of the distance from the clamping element dimension amounts to a maximum of 10%, especially a maximum of 5% and, preferably, a maximum of 1 %. Without taking into account a play of the clamping element in the guide, a movement of the clamping element relative to the guide is preferably limited in at least a partial area of the guide, only in a direction parallel to the surfaces of Contact. Preferably, the guide is configured as emptying in the holding element housing, especially as elongated emptying and, preferably, at least partially curved.

By the fact that the guide "conducts, at least partially, vertically" the clamping element in at least one mounted state, for height adjustment, it should be understood, in particular, that the clamping element housed by the clamping element housing is driven, at least partially, vertically by the guide during height adjustment, and a movement of the clamping element takes place during height adjustment, especially relative to the guide . In particular, a normal vector of at least one contact surface of the guide has at least one horizontal component that does not zero. The term "horizontal component" means, in particular, a component of the vector in a direction parallel to a level plane of the domestic appliance in at least one operating state of the domestic appliance. Preferably, an orientation of the clamping element relative to the housing of the clamping element is maintained, when

less, to a large extent, during height adjustment. By "orientation" of the clamping element relative to the

housing of the clamping element, in particular, an angular orientation of the clamping element is to be understood relative to the clamping element housing, which is especially independent of a position of the clamping element with respect to the clamping element housing . Because of the fact that the

orientation is maintained, "at least, to a large extent", during height adjustment, it should be understood, in particular,

that a maximum modification of an angle between a vector of the normal of any partial surface of the clamping element and a vector of the normal of any partial surface of the clamping element housing during height adjustment ascends, at most, to 30º, especially, at most, at 20º, preferably, at most, at 10º and, especially advantageously, at most, at 5º. Preferably, the guide also conducts the clamping element at least partially horizontally for height adjustment. By "horizontally", it is to be understood, in particular, a direction parallel to the level plane of the domestic appliance in at least one state of operation of the domestic appliance.

By such an embodiment, advantageously high wearing comfort can be achieved. In particular, an adjustable height of the support unit can be achieved advantageously simple and safe, as well as simple for the user. During height adjustment, erroneous handling can be especially avoided. Likewise, an advantageously stable clamping of the clamping element can be provided by means of the clamping element housing, which also presents a need for advantageously small construction space.

In a preferred embodiment of the invention, it is proposed that the guide has, at least, a first fastening point in which the fastening element is maintained through a force of the weight so that at least essentially stationary in at least An operational state. By "clamping point", here it is to be understood, in particular, an area of the guide. In particular, the area of movement of the guide is followed by the clamping point, where the clamping element is moved during the height adjustment conducted along the area of movement. The fact that the clamping element “is maintained, at least essentially stationary,” has to be understood, in particular, that an absolute modification of the position of the clamping element in the operating state ascends, at most, to 3 mm., Especially at most 1 mm., Preferably at most

0.5 mm. and, especially advantageously, at most, at 0'1 mm. Through it, you can get a

advantageously secure clamping of the clamping element in the operational state. Likewise, a convenience of use can be increased, and a plurality of parts can be reduced, as well as, in particular, the production costs linked to it, since additional blocking elements can be dispensed with.

Advantageously, the guide has, at least, a second clamping point in which the clamping element is maintained through a force of the weight so that it is at least essentially stationary in at least one operating state. In particular, the first clamping point and the second clamping point are separated through the displacement area. Thus, a second installation height within the usable space can be advantageously provided for the support unit.

In a particularly preferred embodiment of the invention, it is proposed that the guide present between the first clamping point and the second clamping point, at least, a first reversal point of the movement in which a vertical movement of the clamping element is reversed in a transfer from the first fastening point to the second fastening point. By "point of inversion of the movement", in this context it is to be understood, in particular, a place in the guide in which a component of the horizontal and / or vertical movement of the clamping element changes a direction during height adjustment. In this way, a convenience of use can be increased especially advantageously, since a transition from the first fastening point to the second fastening point is clearly recognizable to a user. Likewise, a secure and reliable fastening of the fastener at the fastening points can be achieved.

Likewise, it is proposed that the guide present between the first clamping point and the second clamping point, at least a second reversal point of the movement in which a horizontal movement of the clamping element is reversed in a transfer of the first point of clamping to the second clamping point. In this way, it can be ensured that the clamping element is arranged in each case next to the first clamping point and next to the second clamping point at the same depth of the usable space.

If the guide has at least one extraction area that is intended for removal of the guide support element, the support element, preferably together with the support unit, can be removed from the usable space, especially for cleaning the Usable space and / or support unit. In the event that the domestic appliance is configured as a cooking appliance with a pyrolytic self-cleaning function of a cooking space, a possibility of extracting the support unit from the useable space advantageously simple and without tools can be achieved, especially before a pyrolytic self-cleaning. In particular, deterioration and / or disadvantageous discoloration of the support unit during pyrolytic self-cleaning can be avoided, especially in the case that the support unit is not enameled. By "extraction area", in particular, a partial area of the guide in which an extraction of the guide holding element is possible is to be understood. Preferably, as a result of a conformation of the guide and / or of the clamping element, an extraction of the guide clamping element in all partial areas of the guide other than the extraction area is excluded. Additionally, the extraction area is intended to introduce the fastener into the guide. In this way, comfort of use can be increased to a greater extent and, in particular, at least to a large extent, involuntary removal of the guide from the fastener can be avoided.

Advantageously, the clamping element housing is arranged next to a side wall that delimits the usable space. By "side wall", it is to be understood, in particular, a wall that delimits the usable space, which runs, at least, essentially, vertically, in at least one operating state of the domestic appliance. The term "vertical" means, in particular, a direction perpendicular to the level plane of the domestic appliance in at least one state of operation of the domestic appliance. A wall that runs, "at least essentially" vertically, has to be understood, in particular, a wall whose surface directed towards the usable space present at each point of the surface a normal vector that differs from a horizontal direction, at most, 30º, especially, at most, 20º, preferably, at most, 10º and, especially advantageously, at most, 5º. The clamping element housing can be fixedly fixed to the side wall preferably through a direct or indirect weld joint, by rivet and / or glue, or detachably again, especially through a threaded joint. , by plug and / or by socket. Also, the clamping element housing can be formed in one piece on the side wall. In the side wall it is preferably a side wall adjacent to a loading opening of the usable space. Through this, advantageous accessibility of the holding element housing can be achieved. Likewise, a complexity of cleaning the clamping element housing can be reduced, especially if the clamping element housing is fixed to the side wall being removable again.

Likewise, a clamping element and a clamping element housing of a home appliance holding device according to the invention are proposed, as well as a home appliance with a home appliance holding device according to the invention. In the domestic appliance it may be especially a refrigeration and / or freezer apparatus, especially a refrigerator and / or freezer, or a freezer chest, a cleaning apparatus, especially a dishwasher or, preferably, a household appliance. cooking, especially a cooking oven.

Other advantages are taken from the following description of the drawing. An exemplary embodiment of the invention is shown in the drawing. The drawing, descriptions and claims contain numerous features in combination. The person skilled in the art will consider the characteristics advantageously also separately, and will gather them in other reasonable combinations.

Figure 1 shows a domestic appliance 38 configured as a cooking oven 40 with a usable space 12 configured as a cooking space 42. The cooking space 42 is delimited by a cooking flask 44, which especially comprises two opposite side walls 36 between yes, a rear wall (not shown), a base 45, and a cover (not shown). A loading opening 46 of the cooking space 42, opposite the rear wall, is locks in a known manner by a door (not shown). The cooking oven 40 comprises a home appliance holding device for adjusting the height of support units 10, 50 within the cooking space 42 with holding elements 14 and holding elements 16, where, in the figure 1, of the clamping elements 14 and the clamping element housings 16, only one is indicated. The support unit 10 comprises a pair of telescopic support rails 48 of which only one is visible in Figure 1. The telescopic support rails 48 are arranged in parallel to the side walls 36 of the cooking flask 44. The telescopic support rail 48 not visible is correspondingly configured, specifically symmetrically to the telescopic support rail 48 visible, where a mirror plane runs centrally through the cooking space 42 and parallel to the side walls 36. The telescopic clamping rails 48 are provided to accommodate a support of cooking product, in particular a cooking pan or a cooking grill ( not represented). Through the telescopic support rails 48, the cooking product support is removable from the cooking space 42 for easy accessibility (not shown). The support unit 50 is configured identically to the support unit 10. The support units 10, 50 are part of the home appliance holding device.

According to the invention, each of the clamping element housings 16 comprises two guides 18, 51, which conduct at least partially partially the clamping elements 14 in at least one mounted state, for the adjustment of the height of the support units 10, 50. The clamping element housings 16 are fixed to the side walls 36 of the cooking flask 44. In the present case, the clamping element housings 16 are screwed to the side walls 36 (not shown). However, alternatively or additionally, any other fixation that is appropriate to a person skilled in the art is also conceivable. Thus, clamping element housings can also be specially formed in a piece in side walls of a cooking flask. Each two clamping element housings 16 identical to each other are arranged next to a side wall 36, one of the clamping element housings 16, on one side of the side wall 36 directed towards the loading opening 46 and, one of the holding element housings 16, on one side of the side wall 36 opposite the loading opening 46. The holding element housings 16 next to the side walls 36 opposite each other are in pairs opposite each other, and they are configured in pairs in a symmetrically specular manner, in which also here the specular plane runs centrally through the cooking space 42 and parallel to the side walls 36.

Figure 2 shows a part of the home appliance holding device extracted from the cooking flask 44, in a rear view. The clamping element housings 16 are formed from sheet profiles, and are in each case formed in one piece. Each housing of fastening element 16 comprises two fixing elements 52, 54 as a plate, which are supported in a state mounted on the side wall 36, and are especially screwed with it (only the fixing elements 52 indicated , 54 of one of the clamping element housings 16). Between the fixing elements 52, 54, each holding element housing 16 has a lifting area 56, which is also configured as a plate and, in particular, parallel to the fixing elements 52, 54. In a When mounted, the lifting area 56 is elevated with respect to the fixing elements 52, 54 in the direction of an interior space of the cooking space 42. In the lifting area 56 of each holding element housing 16 the two are formed guides 18, 51, which are made as emptyings 58, 60 in the sheet profiles. The guides 18, 51 of a holding element housing 16 are arranged one above the other and, in particular, spaced apart from each other vertically. Each guide 18, 51 has two contact surfaces 61, 62 opposite each other and curved, between which the fasteners 14 are driven in an assembled state. A perpendicular distance from the contact surfaces 61, 62 is set at 0.5 mm. greater than a thickness 63 of the fasteners 14 (see Figure 3).

In an orientation corresponding to an orientation in an operational state, the guide 18 has an extraction area 34 at an upper end. The extraction area 34 is characterized by a horizontal orientation of the guide 18. Following the extraction area 34, the guide 18 bends obliquely downwards, in the direction of the loading opening 46, before bending again, forming a first fastening point 26, obliquely upwardly away from the loading opening 46. Next, the guide 18 forms a first curvature 70, which ends in a first fragment of the path 72 straight and directed obliquely downward, towards the opening of load

46. At the end of the first fragment of the path 72, the guide 18 has a second fastening point 30. The second fastening point 30 is formed by the first fragment of the path 72 and a second curvature 74 corresponding to the first curvature 70, adjacent to the first fragment of the path 72. This second curvature 74 ends in a second fragment of the path 76 corresponding to the first fragment of the path 72, at which end a third attachment point 64 is formed. Thus, the guide 18 presents between the first point of clamping 26 and the second clamping point 30, at least, a first reversal point of the movement 32, in which a vertical movement of the clamping element 14 is reversed in a transfer of the first clamping point 26 to the second clamping point 30 (see also figure 7). Also, consequently, the guide 18 comprises between the first holding point 26 and the second holding point 30, at least a second reversing point of the movement 33 in which a horizontal movement of the holding element 14 is reversed in a transfer of the first clamping point 26 to the second clamping point 30. In addition, there are also corresponding movement reversal points between the second clamping point 30 and the third clamping point 64, not indicated in more detail. The guide 51 only differs from the guide 18 in that, in the guide 51, there is no second curvature or a second fragment of the path nor, therefore, a third attachment point.

Figure 3 shows one of the fasteners 14 in an individual isometric view. In a mounted state, on each guide 18, 51 of the clamping element housings 16 each time exactly one clamping element 14 is driven. Each clamping element 14 is made of stainless steel. The fasteners 14 are made in one piece, and essentially have the shape of a twisted cylinder whose thickness 63 is constant, without taking into account bending points 78, 80, 82, and amounts to 7 mm. Starting from a first end 84, the fastener elements 14 first run in a straight line along a first direction 86 to the first bending point 78. At the first bending point 78, the fastener elements 14 are angled angled straight in a second direction 88. Between the first bending point 78 and the second bending point 80, the fastening elements 14 run in a straight line along a second direction 88. In the second bending point 80, the elements of clamping 14 are angled at right angles in a third direction 90. Between the second bending point 80 and the third bending point 82, the clamping elements 14 run straight along the third direction 90. In the third bending point 82, the fasteners 14 are angled at a right angle in a direction opposite to the second direction 88. Between the third bending point 82 and a second end 92, the elements of s Position 14 run in a straight line. The first address 86, the second address 88 and the third address 90 run in parallel to coordinate axes of a Cartesian dextrogiro coordinate system.

The fasteners 14 are configured at the first end 84 as rear grip elements 94, which hold the fasteners 14 in a state mounted by a rear grip behind the fastener element housings 16 in the guides 18, 51 (see figure 2). The fasteners 14 are configured at the second end 92 as support elements 96, which are supported in a state mounted on the fastener element housings 16 (see Figures 1 and 2). Therefore, in an assembled state, the first direction 86 and the third direction 90 are oriented in parallel and, the second direction 88, is perpendicular to the lifting areas 56 of the clamping element housings 16. The clamping elements 14 form between the second flexion point 80 and the third flexion point 82 a fixing area 98, in which the holding elements 14 are fixed in a state mounted to one of the support units 10, 50. As fixing of the fasteners 14 to the support units 10, 50, here any solution that is appropriate to a person skilled in the art is considered. Thus, the fasteners can be specially joined by screwing, riveting, bonding and / or indirect welding to support units. In particular, fasteners can also be formed in one piece together with support units. In the present case, the fasteners 14 are connected to the support units 10, 50 by direct welding.

As shown in Figure 2, in an operational state, the fasteners 14 fixed to the support unit 10 are stationary in the second fastening point 30 of the guide 18 by a force of the weight 28 of the support unit 10 and the fasteners 14. Similarly, in an operational state, the support unit 10 can be stationary in the first fastening point 26 of the guide 18 after a height adjustment . Also, in an operational state, the support unit 10 can also be stationary in the third fastening point 64 of the guide 18 after a height adjustment. Without taking into account a third clamping point, the same applies correspondingly to the clamping elements 14 fixed to the support unit 50 that are supported in the guide 51, and about which therefore it is not entered into detail below.

Figures 4 and 5 show one of the clamping element housings 16 and one of the clamping elements 14 during an extraction of the clamping element 14 of the guide 18 of the clamping element housings

16. Removal of the clamping element 14 of the guide 18 is made possible in the extraction area 34. In the extraction area 34, the guide 18 and the rear gripping element 94 of the clamping element 14 run parallel to each other ( see figure 4). Removal of the rear gripping element 94 takes place by a movement 100 of the clamping element 14 perpendicular to the lifting area 56 of the clamping element housing 16 in the direction of the interior space of the cooking space 42 (see Figure 5) . When this happens, in each case the other fastener 14 fixed to the support unit 10, not shown in Figures 4 and 5, is moved correspondingly, so that the entire support unit 10 can be removed from the space of cooking 42. For the extraction of the fasteners 14 held in the guides 51, the same applies accordingly. An extraction of the support units 10, 50 from the cooking space 42 may be suitable, for example, in a cooking oven 40 with a pyrolytic self-cleaning function, for the care of the support units 10, 50. Also By cleaning the support units 10, 50, cleaning of the support units 10, 50 can be simplified.

Figures 6 and 7 show one of the holding element housings 16 and one of the holding elements 14 during a height adjustment of the corresponding support unit 10. In Figure 6, the clamping element 14 rests stationary on the first clamping point 26. Figure 7 shows how the clamping element 14 is moved from the first clamping point 26 to the second clamping point 30 through of a movement 66 guided along a displacement area 68. When this happens, the clamping element 14 crosses the first curvature 70 and the first fragment of the path 72 of the guide 18. During movement 66, the clamping element 14 reverses as a consequence of the guide 18 a vertical movement at the first reversal point of the movement 32. Also, during the movement 66, the clamping element 14 reverses as a consequence of the guide 18 a horizontal movement at the second inversion point of the movement 33. When this happens, in each case the other fastening element 14 fixed to the support unit 10, not shown in figures 6 and 7, is moved correspondingly, so that The installation height of the entire support unit 10 within the cooking space 42 can be modified. For the adjustment of the height of the fasteners 14 held in the guides 51, the same applies accordingly.

In an alternative embodiment, a rear gripping element of a clamping element can also be configured, by way of example, in the form of a plate. In this case, a guide comprises in an extraction area a preferably circular widening, through which the rear plate-shaped gripping element can be conducted for an extraction of the clamping element. It is also conceivable any other conformation of a rear gripping element of a clamping element, which is appropriate to a person skilled in the art, which differs from a plate shape. Only the fact that the rear gripping element is removable from a guide in an extraction area and that outside the extraction area is fixed in the guide in the direction of an interior space of a usable space is decisive.

 2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The invention of the application presents a clamping device for a height adjustment of a support unit, with at least one clamping element and a housing with a guide that leads, at least partially, vertically to the clamping element. Dependently it is indicated that it has at least one clamping point where the clamping element is maintained by the force of the weight and at least a second clamping point in which the clamping element would also be maintained by the force of the weight , with an inversion point between the two fasteners, another inversion point but which, as claimed, does not depend on the first investment point, and an extraction area. Also dependently it is claimed that this housing element is arranged next to a side wall and a domestic appliance incorporating this fastening device. The claims are formulated very generally. Document D01 discloses a clamping device for a height adjustment of a support unit, in this case a telescopic rail of an oven. In one of its possible embodiments, it has a clamping element and a housing with a guide that leads, at least partially, vertically to the clamping element that is maintained by the force of the weight. In fig 8. a vertical slat (5) is shown, a rail that can occupy two stable positions in height (32,33), being maintained by the force of the weight and moving in the guide (30), which has two points investment and a busty (31) as described in [para. 47]. An extraction area is presented in fig. 6. Figures 1 and 2 show the housing arranged next to a side wall and a domestic appliance, in this case an oven, in which the clamping device is located. In view of this document, claims 1-10 would lack novelty (Article 6.1 of the LP), Document D02 refers to a removable shelf which, given the general nature of the claims, would also affect the novelty of the invention of the application. The intermediate shelves are adjustable in height, there are two fasteners and the shelves are held by the force of the weight. It has an extraction area and is arranged laterally and in a domestic appliance, in this case a shelf. This document also affects the novelty of claims 1-10, as they have been written (Article 6.1 of the LP). Document D03 presents a tray carriage for an oven, with guides to regulate one or more trays in height, maintaining its weight and where the guide elements have fasteners and inversion points and extraction area. In contrast to the invention of the application, it is not arranged alongside a side wall. This document affects the novelty of claims 1-6, as they have been written (Article 6.1 of the LP). Document D04 presents another structure for placing trays in an oven, with guides to regulate in height one or several trays, being maintained by their weight and with two fasteners. This document affects the novelty of claims 1-3, as they have been written (Article 6.1 of the LP). In view of the above documents, the invention of the application would not comply with the patentability requirements established in Article 4.1 of the Patent Law. State of the Art Report Page 4/4
