Description
- The present invention relates to a support bracket for apparatuses, in particular air-conditioning installation units, having the features set out in the preamble of the
main claim 1. - The invention particularly, though in a non-exclusive manner, involves the field of bracket-like fixing devices for supporting the exchange groups for air-conditioning installations.
- In this context, it is known that the heat exchanger groups, which are used in the air-conditioning installations and which supply the diffusors which are provided in the surrounding areas of the buildings to be air-conditioned, have to be arranged and supported outside the buildings or in any case relocated to such a position as to communicate with the exterior.
- Furthermore, it is typical that the formation of the buildings requires that these exchangers be suspended on the external walls of the buildings or on walls near balconies and windows which are directed towards the exterior of a building so as to allow the heat exchange between hot air and cold air in the exchanger. In order to fix these exchangers to the walls, the widespread use of L-shaped brackets which have such dimensions as to have suitable robustness is well-known, a pair of these brackets normally being sufficient, which brackets are fixed either directly to the walls or to guides which in turn are fixed to the walls, for example, with plug type fixing systems.
- These brackets are further provided with seats for inserting fixing screws with which the apparatus is secured to the brackets themselves.
- A first known type provides for the brackets to be constructed with a final preformed L-shaped formation, but this formation is not particularly convenient for the spatial requirements which are involved in the transport and storage operations.
- Furthermore, there are known brackets, in which the portions or wings which compose the L-shaped bracket are constructed to be separate so as to reduce transport and storage spatial requirements, but they require that the installer carry out the relevant assembly before the installation.
- According to another known type, there is provision, if the bracket is prepared in two separate pieces, for them to be assembled in a mutually articulated manner, thereby reducing the transport and storage spatial requirements but nevertheless requiring the installer to carry out the assembly thereof before the operation of fixing to the wall.
- With regard to the materials, conventionally these brackets have been mainly configured using metal material, which material, on the one hand, ensures lightness and adequate mechanical resistance to loads being applied, on the other hand, it exposes the bracket to the action of the atmospheric agents with inevitable damage to the bracket over time, for example, as a result of corrosion phenomena.
- Technical solutions have further been developed for support brackets which are made from plastics material, in particular configured with the pieces of the bracket (horizontal arm and vertical upright) being separate and able to be secured to each other in a fixed or articulated manner.
- The invention is directed towards these types of brackets and the main object is to provide a support bracket for apparatuses, in particular air-conditioning installation units, which is structurally and functionally configured to produce a relative fixing system between the pieces of the bracket which are provided in a state separate from each other, which is easy and rapid to assemble by the installer so as to obtain a bracket which is very lightweight but which at the same time ensures reliability for ensuring adequate mechanical resistance to the loads applied.
- These objects and other objects which will be clearly appreciated below are achieved by the invention by means of a support bracket of the above-mentioned type, which is constructed according to the appended claims. According to an aspect of the invention, the bracket comprises a first and a second bracket portion which are provided for anchoring the bracket to the wall and for supporting and fixing the apparatus to the bracket, respectively, and securing means between the first and second bracket portions in order to mutually secure the portions in an operative condition, in which they take up an L-shaped configuration which is suitable for supporting the apparatus. Preferably, the securing means comprise, at an axial end of the second bracket portion, a tubular through-cavity having a cross-section with a closed, polygonal peripheral profile, which is configured to be engaged, with a substantially positive-locking connection, by a corresponding end portion of the first bracket portion, the relative coupling movement being carried out in the longitudinal development direction of the first bracket portion.
- Preferably, the at least one frame element projects from the end portion of the first bracket portion, transversely relative to the longitudinal direction, against which the axial end of the second bracket portion is intended to abut in the operative condition.
- Preferably, the securing means further comprise, in the second bracket portion, a surface abutment which projects towards the interior of the cavity and which is configured to abut, with mutual surface superimposition, against a corresponding surface portion of the first bracket portion, once the operative condition has been reached.
- Additional features and advantages of the invention will be better appreciated from the following detailed description of a preferred embodiment thereof which is illustrated by way of non-limiting example with reference to the appended drawings, in which:
-
Figure 1 is a perspective view of a support bracket which is constructed according to the invention, -
Figures 2 and3 are additional perspective views of the support bracket of the invention which is shown with detached pieces in respective and different assembly steps, -
Figure 4 is an additional perspective view of the bracket of the preceding Figures in a state shown in an assembled condition, -
Figure 5 is a plan view of the bracket of the preceding Figures, -
Figure 6 is a cross-section along the line VI-VI ofFigure 5 , -
Figure 7 is a side view of a detail of the bracket of the preceding Figures, -
Figure 8 is a cross-section along the line VIII-VIII ofFigure 7 . - With reference to the cited Figures, there is generally designated 1 a support bracket for apparatuses, typically air-conditioning installation units (not illustrated), which is constructed according to the present invention. Normally, there is provision for a pair of
brackets 1 to be provided in a parallel and spaced-apart relationship with suitable relative spacing in order to define the surface support and fixing portions of the apparatus. - The
bracket 1 comprises a first and a second bracket portion which are designated 2 and 3, respectively, and which are configured to be secured to each other at converging ends thereof in order to assume a square configuration which substantially extends in an L-like manner and which is suitable for performing the support function for the apparatus. - In other words, the
first bracket portion 2 forms the vertical upright of the bracket which is provided for anchoring the bracket to the wall while thesecond bracket portion 3 forms the horizontal arm of the bracket which is provided for supporting and fixing the apparatus to the bracket. - Each of the
bracket portions bracket portion 2 and X for thebracket portion 3, thebracket portion 2 extending between oppositelongitudinal ends bracket portion 3 extending between oppositelongitudinal ends - The
bracket 1 comprises securing means between thebracket portions bracket portions ends - The
first bracket portion 2 is provided with asurface 6 which is intended to support and anchor the bracket to the wall or which is intended, in another embodiment, to be engaged with fixing guides (not shown) which are secured to the wall, thesecond bracket portion 3 having asurface 7 for supporting and fixing the apparatus, for example, by means of screws or similar fastening means. To this end, there are provided on thesurface 7 through-holes 8 for engaging with the fixing screws. - It will be observed how the condition with the
bracket portions Figure 2 ) is distinguished by a reduced overall transverse spatial requirement for the benefit of the transportability and the storage of the bracket, the extended L-shaped configuration taken up in the assembled condition (Figure 1 ) instead representing the operative condition capable of performing the support function. - There is further provision for the first and
second bracket portions - The
bracket portions - The securing means 5 comprise at the
axial end 3b of thebracket portion 3 a tubular through-cavity 9 having a main axis Z which is directed perpendicularly to the direction X and which has a cross-section with a closed, polygonal profile, in one embodiment this profile having a quadrilateral and preferably square profile. - The
cavity 9 is configured to be engaged, with a substantially positive-locking connection, by acorresponding portion 10 of thefirst bracket portion 2, theportion 10 extending near theend 2b of thebracket portion 2, the relative coupling movement being carried out in the longitudinal development direction Y of thefirst bracket portion 2. - The
portion 10 advantageously has a box-shaped formation which is defined by side walls which are connected to a base wall, the walls delimiting a hollow internal space, as clearly shown, for example, inFigure 2 . - The securing means 5 further comprise a
frame element 11 which extends from theend portion 10 of thefirst bracket portion 2 in a transverse direction to the longitudinal direction Y and against which theend 3b of thesecond bracket portion 3 is intended to abut in the operative condition suitable for the support function. - The securing means further comprise, in the
second bracket portion 3, asurface abutment 12 which projects with a predetermined inclination towards the interior of thecavity 9 in the region of the upper opening of the cavity and which is configured to abut, with mutual surface superimposition, against arespective surface portion 13 which is provided in the first bracket portion, in a corresponding position, once the operative interconnection condition of the bracket portions has been reached. - With particular reference to
Figures 2 and3 , the mutual securing condition of the bracket portions is achieved from a position (Figure 2 ), in which thetubular cavity 9 is facing, in a spaced-apart condition, theend 2a of thebracket portion 2, and which is followed by a coupling movement, in the direction Y, in which thebracket portion 2 extends through the cavity (Figure 3 ) over the entire longitudinal extent of theportion 2 until reaching the operative condition in which theportion 10 is engaged in a positive-locking manner with the cavity, theportion 3 abutting in the lower region against thelower frame element 11, and in the upper region abutting against thesurface portion 13 with theabutment 12. The sectional view ofFigure 6 clearly shows the positive-locking connection condition of the walls of theportion 10 against the internal walls of thecavity 9 and the condition of moving into abutment against theframe 11 and thesurface portion 13. - In this configuration, the relative blocking between the
bracket portions lower frame 11 and in the region of theupper abutment 12. - In this regard, the
frame element 11 extends over a main portion of the peripheral profile of the section, in a preferred manner it extends along three sides of the square section of theend portion 10 of thevertical bracket portion 2 and thesurface portion 13, for moving into abutment with theabutment 12, extends in the region of the fourth side of the section (the section not affected by theframe 11 in the lower region). This formation together with the box-shaped form of theportion 10 which is intended to engage, with positive-locking connection, with thetubular cavity 9, confers suitable robustness and rigidity on the interconnection zone of the bracket portions, but the securing action between the interconnected portions not requiring the use of any additional fixing means, such as screws or similar fastening elements. - The
bracket 1 is further provided with anti-uncoupling means for thesecond bracket portion 3 from thefirst bracket portion 2, which means are active between thebracket portions flexible extension pieces 15 which are provided in thefirst bracket portion 2, eachextension piece 15 having at a free end thereof arespective locking latch 16 which is intended to engage with acorresponding hole 17 which is formed in thesecond bracket portion 3, when thebracket portions - In greater detail, the
extension pieces 15 are provided with respective opposite walls of theend portion 10 of thebracket portion 2 and thelatches 16 are configured to project externally from the surface profile of the walls. As a result of the effect of this projection, following the coupling of theportion 10 in thecavity 9, eachlatch 16 is moved into a retracted position as a result of the interference with thehorizontal portion 3 of the bracket, this movement resiliently deforming theextension piece 15 so as to generate a resilient return action which moves thelatch 16 to engage with thecorresponding hole 17 when the hole, during the coupling movement, is brought into the region of the latch. In this position, thelatch 16 remains retained in thecorresponding hole 17, performing the locking function for the relative unscrewing movement of the bracket portions. - The disengagement of each
latch 16 from thecorresponding hole 17 can be brought about only by means of a deliberate action with which the latch is pressed (for example, using a tool, such as the tip of a screwdriver), counter to the resilient return applied by the extension piece in order to disengage the corresponding hole. - Therefore, only by simultaneously disengaging both the latches in the manner described above can the uncoupling movement of the second bracket portion from the first bracket portion be released again, which leads to the bracket portions being disassembled.
- Through-holes which are formed in the
bracket portion 2 and which are configured for fixing the bracket to the wall by means of screw type blocking elements are designated 20. - The
hole 20 nearest theportion 10 of thebracket portion 2 is further arranged to be coaxial with ahole 21 which is formed in thebracket portion 3, the coaxiality between the holes occurring when thebracket portions hole 21 and thehole 20 which are coaxial with each other ensures further relative fastening between thebracket portions - The invention thereby achieves the objects set out, affording the advantages mentioned.
- A main advantage involves the fact that, with the bracket of the invention, there are obtained, in conjunction with each other, an extreme lightness of the structure (all the components are made of plastics material) together with a suitable robustness thereof for the resistance to the stresses resulting from the loads being supported, an improved ease of use, both during the transport and storage steps (with separate bracket portions) and in the operative support condition (bracket with interconnected square portions), as well as an improved ease and speed of assembly of the bracket in the extended, square operative configuration, without requiring the installer to use screw type fixing means or similar other fastening elements for interconnecting the bracket portions.
