Description
- The present invention relates to a support device for equipment, in particular air-conditioning installation units, having the features set out in the preamble of main claim 1.
- The invention particularly relates to the field of devices for supporting the external units of the exchange groups for conditioning installations on the floor or ground.
- A support device having the features outlined above is known from
CN 206073297 . - In this field, it is known that the heat exchange groups which are used in air-conditioning installations and which supply the internal units of the diffusers which are provided in the environments of the buildings which are intended to be air-conditioned have to be arranged and supported outside the buildings or in any case positioned in such a position as to communicate with the exterior. The support devices of the external exchange units are typically of two types, that is to say, ones supported in a bracket-like manner in order to hold the units in a projecting manner, for example, coupled to walls, and ones supported on the floor, which are configured to be supported on a surface, such as, for example, the plane of a balcony or a terrace or the ground itself, and to support the exchange units in a stable manner.
- If the external exchange units are arranged in order also to perform the function of heating the environments, the discharge water or condensate water produced during use is typically collected in condensate collection tanks which are arranged under the external exchange units.
- In order to receive and support the tank in a position raised off the ground in the region under the exchange unit, there are known, for example, support devices which are formed by a pair of portal-like frames which are connected to each other with a predetermined spacing by means of transversely extending profiles, in which the support and the fixing of the equipment are brought about on the horizontal cross-members of the portal-like frames and in which the tank is supported under the equipment by means of additional separate coupling elements which can be secured to the frames.
- However, such a solution requires the interconnection of the pair of portal-like frames in order to also make the support device stable and self-carrying as a result of the vertical dimension of the frames necessary to ensure the receiving space of the condensate collection tank and further requires the arrangement and assembly of separate and different coupling elements for supporting the tank.
- A limitation of this solution can be appreciated from the number of components of the support which have to be arranged for supporting the external unit and the tank located below which inevitably increases times and costs not only for production and storage but also for assembly by the same installers.
- Another limitation is that the portal-like frames mentioned above are constructed from metal and are therefore subjected to corrosion phenomena.
- A main object of the invention is to provide a support device for equipment, in particular air-conditioning installation units, which is structurally and functionally configured as defined in claim 1 to overcome the limitations set out with reference to the cited prior art.
- Another object is to provide a support device which is readily and rapidly able to be configured in the operating condition for supporting the external unit and the condensate collection tank underneath in order to assist the installer during the assembly operations.
- These objects and other objects which will be set out clearly below are achieved by the invention by means of a support device of the above-mentioned type, which is constructed according to the appended claims. According to a main aspect of the invention, the device comprises a support leg which extends in an axial direction between a first end which is provided for support on the ground and a second axially opposite end, the leg having a self-carrying structure and comprising a bracket-like portion which is formed so as to be integral with the leg and which projects therefrom transversely relative to the axial direction, in a position between the ends, the bracket-like portion defining a surface which is suitable for supporting in a supporting manner a condensate collection tank, wherein the support leg comprises, at the second end, connection means which are capable of cooperating with respective connection counter-means which are provided on a cross-member which is capable of removably connecting a pair of the legs, and wherein the connection means are also provided at the first end of the leg with a symmetrical and specular configuration with respect to a centre plane of the leg which extends perpendicularly to the axial direction.
- According to another aspect of the invention, the connection means comprise a seat and a beam which is provided internally with respect to the seat, the seat extending in a transverse direction relative to the axial direction and having such dimensions as to receive an end portion of the cross-member with connection by means of coupling in the transverse direction, the beam engaging, during the coupling movement, with a respective slot of the connection counter-means, which slot is formed in the cross-member, the beam and the slot having respective cross-sections which are formed to construct an interlocking retention of the cross-member in the leg, transversely relative to the coupling direction, as a result of the insertion of the cross-member in the seat.

Figure 22 is a partially sectioned perspective view of an assembly which is constructed with the support device according to the invention, for supporting an equipment item. - With reference to the cited Figures, there is generally designated 1 a support device for equipment, typically air-conditioning installation units, which is constructed according to the present invention.
- The device 1 comprises a
support leg 2 in the axial extent direction X of which there are defined a pair ofopposite ends - The
end 2a of the leg is arranged for support on the ground and is axially opposite theend 2b, at which the support of the equipment item is brought about, as will be appreciated in detail from the remaining description. It will be understood that the direction X corresponds under the conditions of use of the support to the vertical direction of gravitational force, that is to say, perpendicular to a hypothetical horizontal plane P of support on the ground. The leg 1 advantageously has a substantially parallelepipedal formation which produces a self-carrying structure which is suitable for locally supporting the equipment item, in accordance with a support system which provides for the use of a plurality of legs. - As will be clearly appreciated from
Figure 12 , for example, the support system of the equipment item provides for using two pairs oflegs 2, the legs of each pair being connected by across-member 3, at therespective ends 2b, so as to form two respective portal-like structures. The equipment item, for example, the external unit of an air-conditioning installation (shown inFigure 14 ) is therefore supported by and fixed to thecross-members 3, by means of suitable positioning of the portal-like structures constructed with thelegs 2. According to a feature of the invention, theleg 2 comprises a bracket-like portion 4, which is formed so as to be integral with the leg and which projects from the leg transversely to the axial direction X, in a position between theends surface 4a which extends perpendicularly to the axial direction X and which has an extent suitable for supporting a local zone of the peripheral edge of acondensate collection tank 5. Therefore, this tank remains supported by thelegs 2 in a position raised off the ground, by being supported on thesurfaces 4a, in the space under the equipment item, which space is defined vertically by the height dimension of the leg (in the direction X). Thesupport leg 2 further comprises, at theend 2b, connection means which are generally designated 6 and which are capable of cooperating withrespective connection counter-means 7 which are provided on thecross-member 3 which is capable of removably connecting each pair oflegs 2, as described above. - The connection means 6 are also provided at the
end 2a of the leg with a specularly symmetrical configuration with respect to a centre plane of the leg which extends perpendicularly to the direction X, which is designated M in the view of the leg ofFigure 4 . At theend 2a, the connection means 6 cooperate with therespective counter-means 7 which are formed on abase 8 for supporting the leg on the ground. - As a result of their structural identity, there will be described below only the connection means 6 which are provided at the
end 2b of the leg. - The connection means comprise a
seat 9 and abeam 10 which is provided internally with respect to the seat. The seat is delimited by a pair of opposing side walls which are both designated 12 and which project from thebase surface 11 of the seat, anadditional end wall 13 which is contiguous with thewalls 12 and opposite anopening 14 of the seat. - The seat 9 (and the beam 10) extends in a transverse direction Y, which is preferably perpendicular, relative to the direction X, with the
beam 10 extending parallel with thewalls 12 and being equidistant therefrom. Theseat 10 has such a dimension as to receive, with form-fitting connection and with reduced connection play or with slight interference, by means of coupling in the direction Y through theopening 14, an end portion of thecross-member 3. During the coupling movement, thebeam 10 engages with arespective slot 15 which is formed in the cross-member. Thebeam 10 and theslot 15 have respective cross-sections which are formed to bring about, with mutual form-fitting connection, an interlocking retention action of the cross-member in the leg, as a result of the engaging insertion of the cross-member in theseat 10. It will be evident that theslot 15 with the cross-section of thecross-member 3 produce theconnection counter-means 7 which are suitable for cooperating with the connection means 6. - In an embodiment, the
beam 10 has a main longitudinal extent (parallel with the Y direction) and is fixedly joined to theseat 9 at the individual oppositelongitudinal ends beam 10 has an H-shaped cross-section relative to the longitudinal extent direction Y, wherein the H-shaped cross-section comprises a core 10c which is connected to a pair ofopposite wings 10d, eachwing 10d having arespective relief 10e, at the opposite side to the core, which extends parallel with the core 10c in the longitudinal direction Y. The H-shaped cross-section is engaged in theslot 15 with a connection which preferably has slight interference, as a result of the contact of the free ends of the pair ofwings 10d and the free ends of the pair ofreliefs 10e with corresponding surfaces of the cross-member which define theslot 15. - In an embodiment, the
beam 10 extends at theends 10a thereof from theend wall 13 of the seat and is connected at theopposite end 10b thereof to anattachment element 10f which projects from thebase surface 11 of theseat 9. In an embodiment, theattachment element 10f has a T-shaped formation, thecore 10g of which projects from thebase 11 of theseat 9 and thewing 10h of which is configured for connection to the H-shaped cross-section of the end of thebeam 10. - There are designated 16 a pair of extension pieces which project from the
wall 13 and from opposite sides of thebeam 10, having a main longitudinal extent which is directed parallel with the direction Y. Theextension pieces 16 are capable of engaging, with reduced coupling play or with slight interference, with respective tubular cavities 3a which are provided longitudinally in thecross-member 3, during the coupling movement thereof with respect to the leg. - The
extension pieces 16 serve to improve the relative connection action between the cross-member and the leg following the relative coupling movement. - In an embodiment, the
extension pieces 16 have a cross-section which corresponds to the cross-section of thebeam 10 which is described above. There is designated 17 a resilient locking tongue which is provided on thebeam 10 near thewall 13. In an embodiment, the tongue extends in continuation of the core 10c, remaining spaced apart from thewings 10d, so as to be resiliently deformable. - The tongue has, at the free end thereof, a tooth-
like formation 17a which projects externally from the surface profile of thebeam 10. As a result of the effect of this projection, following the coupling of the beam in the slot of the cross-member, the tongue is resiliently deformed and consequently thetooth 17a is pressed against the corresponding surface of the cross-member with relevant contact. In this manner, thecross-member 3 remains held inside theseat 9 with the function of acting counter to unscrewing from the seat as a result of the pressing action applied by the tooth which is pressed against the cross-member. - There is designated 8b in the
base 8 a recess which is intended to receive and retain thecorresponding tooth 17a which is provided on the leg in a corresponding position when it is connected to the base. The recess performs the function of a retention means of the tooth so as to prevent the base from moving under the effect of vibrations. - The
cross-member 3 has a tubular formation and is characterized by a cross-section which is repeated in a constant manner in the main longitudinal extent direction thereof. In an embodiment, the section of the cross-member has a rectangular formation. - The cross-member is advantageously provided with a pair of
slots 15 which extend in respective opposing faces of the cross-member, in a specular symmetrical arrangement of the slots themselves, with respect to a centre plane of symmetry of the cross-member which extends parallel with the longitudinal extent direction. With such a formation, one of theslots 15 is intended to be engaged by the pair ofbeams 10 of the respective opposing legs, to which the cross-member is connected, the other opposingslot 15 being capable of being engaged by fixing elements which are conventional per se in order to fixedly join the cross-member to the equipment item in supporting contact therewith. - The fixing elements comprise, for example, screws with respective heads which are slidingly received and retained in the slot, and on the threaded leg of which a respective locking nut is screwed, the leg engaging with a hole which is provided in an attachment edge of the equipment item which is brought into support on the cross-member and which is locked by means of the locking nut.
- In order to improve the mechanical strength characteristics, the hollow section of the tubular profile of the
cross-member 3 has a cellular configuration, that is to say, one which is formed by a plurality of tubular cavities (identical, for example, to the cavities 3a) which are contiguous with each other and which are delimited by internal walls or dividing walls, as clearly shown, for example, inFigure 8 . - The
cross-member 3 can advantageously be constructed as a profile from plastics material, which can readily be cut to size in order to obtain the preselected length required to produce the suitable portal-like support structures of the equipment item, by connecting the cross-member to a pair of opposing legs which are arranged with a specific relative spacing which is selected in accordance with the dimensions and the spatial requirement of the equipment item and the dimensions of the condensate collection tank supported by the legs. - In order to close the ends of the cross-member, there is provided a
cap 3c which is shown in two different configurations inFigures 10 and20 , respectively. It is configured to partially or completely close the tubular cavities which are defined by the cross-section of the cross-member. - The plate-
like base 8 is configured to form the foot for supporting thesupport leg 2 on the ground. There are provided on thebase 8 the connection counter-means 7, that is to say, theslot 15 which is formed in aprojection 21 of the base, which cooperate with the connection means 6 which are provided at theend 2a of the leg. In greater detail, theprojection 21 is intended to be coupled (through the opening 14) in theseat 9 of theend 2a of the leg, substantially with form-fitting connection and with reduced coupling play, with concurrent engagement of thebeam 10 in theslot 15 and engagement of theextension pieces 16 in corresponding cavities (which cannot be seen inFigure 15 ) which are provided in the projection and which have similar structures to that of the cavities 3a. - There is designated 8c a wall which projects from the
base 8 and which is intended to act as an element for closing theopening 14 of the leg when the leg is connected to the base (Figure 16 ). - There are designated 22 a pair of fixing clamps for the
base 8 which are structurally independent of the base and which can be associated therewith in order to lock the base to the ground, for example, with screw type fixing mean which cooperate with the clamps. In greater detail, eachclamp 22 has afirst portion 22a which is provided with a fixinghole 23 and which extends into asecond portion 22b which is intended to be received in a respective loweredsurface portion 24 of the base. Thesecond portion 22b of the clamp is further provided to be inserted and retained between theprojection 21 and thebase 8, by means of an opening which is generated where applicable in aregion 25 for pre-breaking which is defined between the projection and the lowered portion, as shown inFigure 14 . - By means of the connection of the
clamps 22 to thebase 8, which are arranged in relative alignment at opposite sides of the base, the base remains effectively locked in the support plane following the fixing of theclamps 22, for example, by way of screw type means which are engaged in theholes 23. Thebase 8 may have on theindividual face 8a directed towards the support plane aframe 8d which comprises elastomer material and which has antivibration properties, for example, obtained with a co-moulding technique of such a material on a peripheral profile of the base. - The
base 8 may further be constructed in two portions (Figure 17 ) as a result of moulding requirements, which are intended to be connected to each other in an irreversible manner. - In a generally similar manner, the
support leg 2 may also be advantageously constructed in two portions (Figure 3 ) which are configured to be connected to each other with locking of the irreversible type. - As shown in
Figure 3 , one of the portions in which the support leg is constructed has the bracket-like portion 4 and the pair of T-shapedattachment elements 10f, the other of the portions has theseat 9 with thecorresponding beam 10. - In the relative locking step of the portions, each
attachment element 10f of one of the leg portions is connected to the free end of thecorresponding beam 10 which is provided in the other leg portion. Eachbeam 10 is constructed therein as a projecting structure which extends from theend wall 13 in order then to be secured at the opposite end with thecorresponding attachment element 10f. - With reference to
Figure 20 , aportion 3b of thecross-member 3 with a suitable reduced length may be able to be configured as a joint element between a pair oflegs 2 which are arranged in a configuration in which a leg is arranged vertically on the other leg, in the direction X. In this application, theportion 3b of the cross-member is connected to the connection means 6 provided at theend 2b of the leg underneath and to the connection means provided at theend 2a of the leg above. Such a configuration is suitable for constructing, if needed for installation-related requirements, a height of the support which is doubled with respect to the height of a single leg. - In another application variant (
Figure 21 ), there may be provision for an accessory 27 which has the formation of theleg 2 but which does not have the bracket-like portion 4, the height of which in the axial direction X is equal to half of the height of the leg. This accessory may be connected to a leg by means of the joint element which is formed by theportion 3b of the cross-member in order to bring about an overall height of the support which is equal to approximately one and a half times the height of thesingle leg 2 if installation-related requirements require such a configuration. - It will be evident that the
support leg 2 may therefore be configured as a type of base element for a modular system, with which, as a result of the connection interfaces which are provided in the leg, various connection combinations can be obtained between the above-described components (such as the leg, the cross-member, the joint element, the base, the accessory mentioned), the combinations allowing the configuration of the support device which is most suitable for the various installation requirements which may occur to be produced. Particular reference may be made here to the height dimensions of the support leg and length of the cross-member and the spatial requirement of the support which is connected with the dimension of the condensate collection tank which is intended to be supported in the space under the equipment item. - The invention thereby achieves the objectives set out, achieving the advantages set out with respect to the known solutions.
- A first advantage involves the fact that, as a result of the support device of the invention, it is possible to configure a support structure simply by shaping or cutting to size the cross-members with the length suitable for connecting the legs in order to support the condensate collection tank having the most suitable dimensions.
- Another advantage is that it is unnecessary to provide specific coupling or support elements for the condensate collection tanks to be applied to the supports.
- Another advantage is that no screw type fixing means or the like is required to connect the cross-member to the corresponding pair of legs, in order to provide the portal-like frame for supporting the equipment item, nor is any interconnection element required between the portals, as a result of the self-carrying structure of the support legs according to the invention.
- Another advantage is that the support device of the invention is configured to bring about, in a modular manner, a variety of configurations which are suitable for meeting different installation-related requirements (for example, for dimensions, heights of the support, for dimensions of the condensate collection tank, etcetera).
