Description

BRACKET FOR SUPPORTING AIR-CONDITIONING UNITS
DESCRIPTION
Field of application of the invention [001] The present invention is related to the technical field of supports for operating units for civil and/or industrial use and the subject of the same is a supporting bracket for air conditioning units.
State of the art
[002] As is known, air conditioning systems (air conditioning, heating) generally comprise one or more operating units equipped with a compressor, an electric motor and a circuit constituted by pipes or coils, within which a carrier fluid circulates.
[003] This unit is often installed outside the place for which air conditioning is required. [004] In general, the units are fixed to a masonry wall of a building by means of a special supporting bracket made of a metallic material.
[005] As a rule, this type of bracket comprises a pair of substantially L-shaped supports, one of which is intended to be anchored to the wall.
[006] The other support projects horizontally from the wall in such a way that the feet of the air conditioning unit can be rested thereon and retained.
[007] The air conditioning unit is generally equipped with two pairs of feet positioned at the bottom, which are then firmly fixed to the horizontal supports of the bracket.
[008] T o strengthen the bracket, there is also a crosspiece whose ends are firmly joined to the horizontal supports.
[009] This type of supporting brackets was specifically designed to be used when the air conditioning unit needs to be positioned in proximity to the load-bearing wall.
[0010] In other words, the supports of these brackets must be directly anchored to the load-bearing wall, avoiding the interposition of cladding elements that are not suited to support the weight of the air conditioning unit between the wall and the bracket.
[0011] The main problem with this type of supporting brackets, therefore, lies in that they cannot be used if the load-bearing wall is covered with a cladding material that is structurally fragile.
[0012] This situation often occurs because the cladding material can be constituted by overcladding material placed on the outside of a building, or a heat or sound insulating layer placed on an interior wall, or even a decorative element superimposed on a fagade of a building.
[0013] Furthermore, any adaptation of the current supporting brackets for applications requiring fixing to walls covered with layers of various types has a rather strong impact from an aesthetic point of view.
[0014] These brackets, in fact, have a relatively complex structure, characterized by the presence of many components; such a configuration heavily impacts the aesthetic style of the wall intended to support the air conditioning unit.
Documents KR 2015 0136342, WO2019/175741 and KR 200 181 147 describe supporting brackets intended to support one or more air conditioning units. However, even this type of supporting brackets is affected by the drawbacks described above. Presentation of the invention
[0015] The present invention intends to overcome the technical drawbacks illustrated above by providing a supporting bracket for air conditioning units which is particularly efficient and high performing.
[0016] In particular, the main object of the present invention is to provide a supporting bracket for air conditioning units that is particularly suitable for installation on walls covered with external cladding layers.
[0017] Another object of the present invention is to provide a supporting bracket for air conditioning units that is suited to facilitate the installation of the unit itself; in particular, said bracket is made up of elements that can be assembled at different times, in such a way as to facilitate the installation of the air conditioning unit even when the latter is put into operation after the load-bearing wall has been built.
[0018] A further object of the present invention is to provide a supporting bracket for air conditioning units that is particularly sturdy and durable.
[0019] Another object of the present invention is to provide a supporting bracket for air conditioning units that has a limited number of components and is therefore easy to assemble.
[0020] A further object of the present invention is to provide a supporting bracket for air conditioning units that is easy to manufacture and particularly economical.
[0021] Still, it is not the least object of the present invention to provide a supporting bracket for air conditioning units that is suited to minimize the aesthetic impact of the unit on the wall where it is installed.
[0022] These objects, together with others that will be better illustrated below, are achieved by a supporting bracket for air conditioning units of the type according to claim 1.
[0023] Other objects, which will be better described below, are achieved by a supporting bracket for air conditioning units according to the dependent claims.
Brief description of the drawings [0024] The advantages and characteristics of the present invention are clearly illustrated in the following detailed description of some preferred but not limiting embodiments of a supporting bracket for air conditioning units, which refers in particular to the following drawings:
- Figure 1 and Figure 2 show two perspective views of a supporting bracket for air conditioning units anchored to a load-bearing wall;

[0025] The present invention concerns a supporting bracket for air conditioning units U, which here below is indicated by the reference number 1.
[0026] This bracket is suited to be anchored to a load-bearing wall P or to a supporting structure, which is also a load-bearing structure.
[0027] In the context of the present invention, the term "air conditioning unit" is intended to refer to all pieces of equipment suited to promote the cooling and/or heating of a room, which must be installed in the vicinity of the room itself (for example, outside a building). [0028] More specifically, the air conditioning unit U supported by the bracket 1 that is the subject of the invention is provided with a plurality of supports A (generally, feet) arranged at a predetermined distance di.
[0029] Generally, the air conditioning unit U is provided with two or several pairs of supports (or feet) A and the feet of each pair are spaced from each other by the distance di
[0030] The bracket 1 that is the subject of the present invention comprises at least one pair of supports 2 having an upper surface 3 intended to come into contact with the supports A of the air conditioning unit U.
[0031] In the embodiment of the invention illustrated in the Figures, there is a single pair of supports 2 which are spaced by a distance då essentially equal to the distance di that separates the feet A of the air conditioning unit U.
[0032] Said supports 2, therefore, are suited to come into contact with the feet A of the air conditioning unit U in order to promote the support and the lift thereof to a predetermined height from the ground.
[0033] Conveniently, the supports 2 can have a rectilinear and substantially elongated shape.
[0034] More specifically, each support 2 can extend along a respective longitudinal extension direction indicated by the reference letter X in the drawings.
[0035] Furthermore, the extension directions X of the supports 2 can be substantially parallel to each other.
[0036] As better illustrated in Figure 1 and Figure 2, each support 2 can have a substantially U-shaped cross section.
[0037] In particular, each support 2 is shaped in such a way that the U-shaped cross section is constituted by three distinct, substantially rectilinear and flat sections: two of said sections 29 define the sides of the “U” while the central section 30, which is also flat and rectilinear, defines the base of the “U” and has its ends joined to the sections 29 that define the sides.
[0038] This special shape of the support 2 makes it possible to define a substantially flat upper surface 3 (corresponding to the external surface of the section 30 that defines the base of the “U”), whose function is to come into contact with the supports A (or feet) of the air conditioning unit U.
[0039] Furthermore, the supports 2 can have a variable thickness Si : minimum thickness Si_min at the ends 4, 5 and maximum thickness Si_max at the center line of the support 2. In the figures, the symbol p indicates the middle plane of the supports 2.
[0040] In the case of the bracket 1 shown in the Figures, each support 2 can be obtained from sheet metal, with the following processing steps: i) shearing, ii) bending to form a “U”.
[0041] The support 2, therefore, can have an upper surface 3 (substantially flat) and one pair of substantially parallel side walls 6.
[0042] The width wi of the side walls 6 defines the thickness Si of the support 2 and, according to what has been explained above, said width wi varies between a minimum value and a maximum value, in such a way as to define a support 2 whose thickness also varies between the two values, minimum Si_mm and maximum Si_max. [0043] In this case, the support 2 can have a thickness s^ that increases progressively between the minimum value Si_mm (associated with the ends 4, 5) and a maximum value Si_max (associated with its middle portion).
[0044] In the context of the present invention, the expression "middle portion" or "center line" is intended to refer, for an element having a predetermined length I, to the part of the same element located around the half said length (I/2).
[0045] By way of indication, the minimum value Si_mm of the thickness of the support 2 can be included between 25mm and 45mm while the maximum value Si_max of the thickness of the support 2 can be included between 50mm and 70mm.
[0046] The realization of a support 2 having the following geometric characteristics:
- substantially U-shaped cross section (that is, constituted by rectilinear and flat sections 29, 30 defining the sides and the base of the “U”);
- variable thickness Si (minimum thickness Si_mm at the ends and maximum thickness Si_max at the center line), makes it possible to obtain some particular advantages. Firstly, the U-shaped cross section provides high structural rigidity to each support 2, so that it is able to withstand the weight of the air conditioning unit U without deforming or bending over time. Furthermore, the variation of the thickness Si of the support according to the configuration described above (greater at the center line and minimal at the ends) makes it possible to significantly reduce the overall weight of the bracket 1 (while at the same time reducing the costs related to the raw material) and, in any case, to maintain the high structural rigidity of the support itself. In other words, the combination of the two features i) U-shaped cross section and ii) variation of the thickness allows to obtain a bracket 2 that is light, strong, and substantially non-deformable, suited to support the weight of the air conditioning unit over time with no need for maintenance or replacement operations. [0047] Furthermore, each support 2 can have an overall length included between 300mm and 700mm and preferably close to 500mm.
[0048] Conveniently, the bracket 1 comprises at least one crosspiece 7 suited to connect all the supports 2 with one another.
[0049] In the configuration of the bracket shown in the Figures, there is a single rectilinear and elongated crosspiece 7.
[0050] The expression "single crosspiece" used in this description is intended to refer to a component (crosspiece 7) present in the bracket 1 that is the subject of the invention as just one unit or specimen (that is, in a number equal to one).
[0051] By way of example, the length lå of the crosspiece 7 can be included between 700mm and 1000mm.
[0052] Furthermore, the crosspiece 7 can extend along a substantially transverse extension axis Y (and orthogonal to the extension axis X of each support 2) so as to lie in a substantially orthogonal position with respect to the supports 2.
[0053] The crosspiece 7 can have substantially U-shaped cross section, too, so as to define a substantially flat upper surface 8.
[0054] In particular, the crosspiece 7 is shaped in such a way that the “U” cross section is constituted by three distinct, substantially rectilinear and flat sections: two of said sections 31 define the sides of the “U” while the central section 32, which is also flat and rectilinear, defines the base of the “U” and has its ends joined to the sections 31 that define the sides.
[0055] Also the crosspiece 7 can be obtained from flat sheet metal on which the following processing steps have been performed: i) shearing, ii) bending so as to form a “U”. [0056] The crosspiece 7, therefore, can have a flat upper surface 8 (corresponding to the external surface of the section 32 that defines the base of the “U”) and one pair of substantially parallel side walls 9.
[0057] The width wå of the side walls 9 defines the thickness så of the crosspiece 7. [0058] In particular, the width wå of the side walls 9 can vary between a minimum value and a maximum value, so as to define a crosspiece 7 whose thickness så also varies between the minimum value S2_min and the maximum value S2_max.
[0059] In this case, as can be better observed in Figure 3, the crosspiece 7 may have a thickness så that increases progressively between a minimum value S2_min (associated with its ends 10, 11) and a maximum value S2_max (associated with its middle portion). In the figures, the symbol tt' indicates the middle plane of the crosspiece 7.
[0060] The realization of a crosspiece 7 with the following geometric characteristics:
- substantially U-shaped cross section (that is, constituted by rectilinear and flat sections 31, 32 defining the sides and the base of the “U”);
- variable thickness så (minimum thickness S2_min at the ends and maximum thickness S2_max at the center line), makes it possible to obtain some particular advantages. Firstly, the U-shaped cross section provides high structural rigidity to each crosspiece 7, so that it is able to withstand the weight of the supports 2 of the air conditioning unit U without deforming or bending over time. Furthermore, the variation of the thickness så of the crosspiece 7 according to the configuration described above (greater at the center line and minimal at the ends) allows to significantly reduce the overall weight of the bracket 1 (while at the same time reducing the costs related to the raw material) and, in any case, to maintain the high structural rigidity of the crosspiece itself. Analogously to what has already been described with reference to the support 2, the combination of the two features i) U- shaped cross section and ii) variation of the thickness allows to obtain a crosspiece 7 that is light, strong, and substantially non-deformable, suited to support the weight of the supports 2 and of the air conditioning unit over time with no need for maintenance or replacement operations.
[0061] As can be seen in Figure 2, each support 2 can be provided with a first seat 12 suited to allow the (partial or total) insertion of the crosspiece 7 therein.
[0062] Typically, the first seat 12 is obtained by means of one pair of notches or recesses made in the side walls 6 of the support 2.
[0063] The shape of the first seat 12 can be substantially complementary to the cross- sectional shape of the crosspiece 7 so as to allow the partial or total insertion of the latter. [0064] For example, the first seats 12 can be substantially U-shaped and have the same or slightly larger dimensions than the crosspiece 7 (also U-shaped).
[0065] The first U-shaped seat 12 obtained in the support 2 is an opening which is shaped so as to match the U-shaped cross section of the crosspiece 7 and delimited by three edges created on the side wall 6 of the support 2: two edges 33 are substantially vertical and rectilinear, parallel to each other, and the other edge 34 is substantially horizontal and rectilinear, with its ends joined to the two vertical edges 33.
[0066] Furthermore, the first seats 12 can be open at the bottom so that the crosspiece 7 can be inserted therein from below.
[0067] In this way, it is possible to promote the mutual engagement between the support 2 and the crosspiece 7 due to the fixing action resulting from the insertion of the latter into the first seat 12.
[0068] Conveniently, the assembly of the crosspiece with the pair of supports produces a first single element 35, substantially H-shaped, whose function is to support the air conditioning unit U.
[0069] First fixing means 14 may also be provided to promote the fixing of the supports 2 to the crosspiece 7 with a distance då that can be selectively varied between a predetermined minimum value d2_min and a predetermined maximum value d2_max.
[0070] By way of indication, the first fixing means 14 can be configured to vary the position of the pair of supports 2 on the crosspiece 7 in such a way as to define a distance då between them, said distance då being between a minimum value d2_min close to 400mm and a maximum value d2_max close to 950mm.
[0071] The presence of fixing means 14 suited to fix the pair of supports 2 so that they are separated by the distance då makes the bracket 1 that is the subject of the present invention particularly flexible, as it will be possible to use it for a wide range of air conditioning units, the size of which can vary considerably depending on the type of system installed in the building.
[0072] Conveniently, the first fixing means 14 can include one or more slots 15 obtained in the upper surface 8 of the crosspiece 7.
[0073] This configuration is illustrated in Figure 2. In this case, the crosspiece 7 is provided with one pair of slots 15 that are substantially symmetrical with respect to the middle plane tt' of the crosspiece.
[0074] The length U of the slot 7 can vary depending on the value of the minimum distance d2_min to be achieved between the supports 2.
[0075] Thanks to the presence of the slot 15, it is possible to continuously adjust the distance då that separates the supports 2 between the respective minimum value d2_min and maximum value d2_max.
[0076] In the case where said minimum distance d2_min is substantially close to 400mm and the crosspiece 7 has a length of approximately 10000mm, the length U of each slot 15 will be approximately 250mm.
[0077] An alternative configuration of the first fixing means 14 is illustrated in Figure 1. [0078] In this case, there is a series of holes 16 made in the upper surface 8 of said crosspiece 7 and distributed along its extension.
[0079] It is possible to group the holes 16 of the series in pairs, wherein each hole 16 of said pair is arranged symmetrically with respect to the center line of the crosspiece 7 and the overall distance that separates the holes 16 of each pair defines a predetermined distance då between the supports 2.
[0080] In other words, the series of holes 16 makes it possible to define determined and fixed values for the distance då that separates the supports 2, wherein said distance då can therefore be discretely adjusted by selecting intermediate values included between the minimum value d2_min and the maximum value d2_max.
[0081] However, in both configurations of the first fixing means 14 described above a through hole 17 is made on the respective support 2 and at the center line of the latter. [0082] Said hole 17 is suited to be aligned with the slot 15 or with the holes of the series 16 made on the crosspiece 7; the bracket 2 can be locked onto the crosspiece 7 by inserting a threaded screw through the holes 16, 17 or the slots 15 and then screwing a tightening nut thereon.
[0083] Obviously, the screw and the nut can be replaced by any equivalent type of tightening element capable of promoting the selective locking of the bracket 2 onto the crosspiece 7.
[0084] The supporting bracket 1 comprises also a fixing plate 18 intended to be selectively anchored to the load-bearing wall P of a building.
[0085] Furthermore, the fixing plate 18 is smaller than the shape defined in plan view by the first single element 35 having substantially the shape of an “H” and defined by the pair of supports 2 joined together by the crosspiece 7.
[0086] As better illustrated in the Figures, the dimensions and the overall size of the plate 18 are substantially smaller than those of the H-shaped single element 35 intended to support the air conditioning unit U.
[0087] Also in this case, the dimensions of the plate 18 are selected in such a way as to reduce the overall dimensions of the bracket 1 but at the same time still allowing it to support the full weight of the bracket itself and of the air conditioning unit connected to it.
[0088] More specifically, said plate 18 can comprise an external surface 19 intended to come into contact with the load-bearing wall P by means of appropriate bolts and/or anchors (not illustrated in the figures).
[0089] Advantageously, the bracket 1 comprises a single, substantially elongated connection element 20 having one end 21 anchored to the fixing plate 18.
[0090] The expression "single connection element" used in this description is intended as referring to a component (the connection element 20) present in the bracket that is the subject of the present invention as just one unit or specimen (that is, in a number equal to one).
[0091] The use of a single connection element 20 as specified above allows to obtain a bracket 1 which is particularly simple to install and has a limited number of pieces to be assembled together. Consequently, the use of a single connection element 20 makes it possible to define a bracket 1 that is particularly flexible and light, even if suited to support the weight of an air conditioning unit U.
[0092] In a first embodiment of the bracket 1 , the connection element 20 can be obtained from a piece of metal tube whose diameter is included between 40mm and 80mm and whose cross section is between 6mm and 15mm.
[0093] The cross section, thickness, and dimensions of the single connection element 20 are selected in such a way that it can support the weight respectively associated with the first single element 35, constituted by the supports 2 and the crosspiece 7, and with the air conditioning unit U without bending or breaking.
[0094] The outer surface 22 of the single connection element 20 is also intended to interact with the crosspiece 7 in such a way as to promote selective anchorage thereof in a predetermined position.
[0095] The use of a single connection element 20 makes the bracket 1 particularly easy to make; furthermore, the fact that there is just one connection element 20 makes it possible to fulfill certain technical functions that are described below.
[0096] The connection element 20 is substantially rectilinear and extends along a longitudinal extension direction Z substantially parallel to the extension direction of each support X (and substantially orthogonal to the extension direction of the crosspiece Y). [0097] In this way, the anchorage of the connection element 20 to the crosspiece 7 defines a substantially cross-shaped structure in which each element among these is substantially orthogonal to the other.
[0098] Conveniently, the connection element 20 and the fixing plate 18 form a second single element 36 which is distinct from the first single element 35 constituted by the crosspiece 7 and the supports 2.
[0099] The second single element 36 serves as a spacer component for the first single element 35 (that is, it serves to separate the latter element 35 from the load-bearing wall or the supporting structure).
[00100] The advantage of dividing the bracket 1 into two separate single elements 35, 36 lies in that the latter can be assembled at different times.
[00101] More specifically, the second single element 36 that serves the function of a spacer can be anchored to the load-bearing wall or to the supporting structure during the construction of the latter (or during renovation or maintenance works such as, for example, the application of heat insulation cladding to the outside of the wall).
[00102] The first single element, H-shaped and suited to support the air conditioning unit U, can be permanently anchored to the second single element 36 that serves as a spacer even after the latter has been installed, for example even months or years later.
[00103] Furthermore, the length U of the connection element 20 can be selected so that it is the same as or greater than the length of each individual support 2.
[00104] In the configuration of the bracket 1 shown in the Figures, the connection element 20 has a length U that exceeds 500mm.
[00105] In this way, the distance d3 that separates the fixing plate 18 and the end 4 of the support 2 that is closest to said plate is substantially equal to or greater than half or 50% of the length U of the support 2 itself (U > li 12).
[00106] In this way, the bracket 1 that is the subject of the present invention makes it possible to support the air conditioning unit U while keeping it separated from the wall P, at a distance equal to or greater than half the length of the support 2.
[00107] This special configuration is particularly advantageous when the load-bearing wall P is covered with a relatively fragile cladding layer R and that therefore cannot serve as an anchorage surface for the plate 18 of the bracket 1.
[00108] In this condition, therefore, it will be necessary to make a passage K on the cladding layer R to allow the connection element 20 to be inserted therethrough.
[00109] This situation is schematically illustrated in a clear manner in Figure 5.
[00110] In this case, therefore, it is possible to anchor the fixing plate 18 to the load- bearing wall P even when the latter is covered with a layer of relatively fragile material R (for example, thermal cladding placed on the outside of a building).
[00111] Furthermore, the presence of a single connection element 20 suited to mechanically connect the crosspiece 7 to the plate 18 makes it possible to obtain a bracket 1 that can minimize the adjustments to be made to the insulation layer R. [00112] In fact, the configuration of the supporting bracket 1 described above makes it possible to preserve the original structure of the cladding layer R as much as possible, as for its installation it is necessary to provide only one passage (in the cladding layer R) through which the connection element 20 is inserted.
[00113] Conveniently, the cross section of the connection element 20 can have a circular or polygonal shape. [00114] In a further configuration of the bracket 1 , the connection element 20 can be obtained from a piece of drawn metal having a given cross section (for example, circular, square, rectangular, etc.) with a thickness included between 6mm and 15mm.
[00115] In the configuration of the bracket 1 illustrated in the Figures, the connection element 20 is obtained from a piece of circular tube with a predetermined length U (selected so that it is not less than the length of the supports 2).
[00116] It is also possible to make a second seat 23 in the crosspiece 7.
[00117] Typically, the second seat 23 can be obtained on the side walls 9 of the crosspiece 7 through a pair of notches or recesses.
[00118] The shape of the second seat 23 can be substantially complementary to the cross-sectional shape of the connection element 20 in such a way as to permit the partial or total insertion of the latter into the seat itself.
[00119] For example, in the case where the connection element 20 has circular cross- section (as in the bracket shown in the Figures), the second seat 23 can have a substantially circular or semicircular shape with diameter equal to or slightly greater than the diameter of the tube that defines the connection element 20.
[00120] The second seat 23 can be open at the bottom so that the connection element 20 can be inserted therein from below.
[00121] In this way, it is possible to promote the mutual engagement between the connection element 20 and the crosspiece 7 essentially by fixing the former in the second seat 23.
[00122] Advantageously, second fixing means 24 can be provided which are suited to fix the crosspiece 7 to the connection element 20 in a selectively variable longitudinal position.
[00123] The second fixing means 24 thus allow to selectively move the crosspiece 7 towards/away from the fixing plate 18.
[00124] This adjustment makes it possible to vary the distance d3 that separates the end 4 of the supports 2 from the fixing plate 18 according to the needs or the overall dimensions of the air conditioning unit U.
[00125] The second fixing means 24 can comprise a slot with predetermined length, made on the outer surface 22 of the connection element 20.
[00126] Alternatively, as better illustrated in the Figures, the slot can be replaced by a series of holes 25 arranged with constant or variable pitch along the extension direction Z of the connection element 20.
[00127] The second fixing means 24 can also comprise a further hole 26 made on the center line of the crosspiece 7, said hole 26 being intended to be aligned with the slot or with a hole 25 of the series formed on the connection element 20.
[00128] The stable locking of the crosspiece 7 onto the connection element 20 can be achieved by means of a screw inserted through the slot or through the holes 25, 26 (firmly secured with a locking nut) or by means of any other equivalent locking element known per se.
[00129] The bracket 1 that is the subject of the present invention has some special characteristics that are highlighted below:
- there is at least one pair of supports 2 (generally, a single pair);
- there is at least one crosspiece 7 (generally, a single crosspiece);
- there is a single connection element 20;
- there is a single bracket 18.
[00130] Advantageously, the crosspiece 7 is connected exclusively to the following components: the supports 2 and the single connection element 20.
[00131] The crosspiece 7, therefore, is not directly connected to the supporting bracket 18, that is, these two components are physically separate from each other (there are no contact areas or points). However, when the bracket 1 is assembled, the crosspiece 7 and the bracket 18 are operationally connected through the single connection element 20.
[00132] Furthermore, the fixing plate 18 is connected exclusively to the single connection element 20; in other words, said plate 18 does not have any areas or points in contact with other components of the bracket (the crosspiece 7 and the supports 1). [00133] As a matter of fact, the plate 18 is physically separate from the supports 2 and the crosspiece 7 (and is therefore also separate from the first single element 35 having the shape of an "H" and configured to support the weight of the air conditioning unit U). [00134] However, when the plate 18 is assembled, the plate 18 and the first single element 35 are operationally connected through the single connection element 20. [00135] The exclusive connections described above (crosspiece 7 with supports 2 and single connection element 20; plate 18 with single connection element 20) allow to define a particularly flexible and easy-to-assemble plate, as already exhaustively described above. [00136] In particular, said exclusive connections make it possible to define:
- a first single element 35 substantially in the shape of an “H”;
- a second single element 36 serving as a spacer;
- a bracket 1 having a substantially cross-shaped configuration when the two single elements 35, 36 are connected to each other.
[00137] Conveniently, a bracket 1 made as described above can be suited to support a weight associated with the air conditioning unit ranging between 90 kg and 160 kg. [00138] Moreover, the type of exclusive connections described above makes it possible to easily position the air conditioning unit U above the supports 2 (that is, above the first single H-shaped element 35) even when the entire bracket 1 is arranged on the floor and the plate 18 has not yet been anchored to the wall P.
[00139] Alternatively, the air conditioning unit U can be placed above the first single H- shaped element 35 when the latter has not yet been anchored to the second single element 36 (the latter being made up of the plate 18 and the single connection element 20).
[00140] In this case, the second single element 36 can be anchored to a load-bearing wall P at a different time than when the air conditioning unit U is fixed to the first single element 35.
[00141] For example, the second single element 36 can be anchored to the wall P before the air conditioning unit U is positioned on the first single element 35.
[00142] In this case, the air conditioning unit U (already previously fixed to the first single H-shaped element 35) must be lifted in order to operationally connect it with the respective second single element 36 already anchored to the wall P.
[00143] As already underlined several times above, the flexibility in the installation, respectively, of the bracket 1, which is the subject of the present invention, and of the air conditioning unit U on the wall P is due to the special configuration of the exclusive connections provided for the components of the bracket.
[00144] The present invention can be carried out in other variants, all falling within the scope of the inventive features claimed and described herein; these technical features can be replaced by different technically equivalent elements and materials; the shapes and dimensions of the invention can be any, provided that they are compatible with its use.
[00145] The numbers and reference signs included in the claims and in the description are only intended to increase the clarity of the text and must not be considered as elements limiting the technical interpretation of the objects or processes identified by them.
