Support particularly for condensing units

Abstract: A support particularly for condensing units used in air conditioning systems. The support comprises a box-like body (2) which has, on the opposite side with respect to the side that rests on the ground, a first base (5) provided with a hole (9) at which a bolt or nut is arranged on the underside. A second base (6), provided with an axial slot (12) for slidingly locking the head (13) of a nut (14), is provided in the box-like body (2).

Description: The present invention relates to a support particularly for condensing units. Currently, the provision of an air conditioning system entails the use of an external condensing unit and of an internal unit, which are mutually connected by means of an electrical connection and by means of two thermally insulated pipes adapted to convey the refrigerant fluid between the two units. Document US-A-3 722 845 discloses a support in the form of a ground mounting base with four holes at which a fixing means is arranged. Floor-mounting of the condensing unit raises the problem of vibrations when in operation: for this purpose, it is known to use floor-mounted supports which are substantially constituted by a box-like body made of plastic material being open at its ends and shaped essentially like a parallelepiped; such box-like bodies are internally provided with a cellular structure and have, on the surface that lies opposite the surface that rests on the ground, a longitudinal slot which accommodates the head of a bolt which is slidingly associable therewith. However, this conventional solution suffers drawbacks: the installer must in fact place the condensing unit on top of a pair of supports, in which he must have placed a pair of bolts beforehand, taking care that the center distance between the two protruding threads of the two bolts of each support corresponds to suitable holes provided in mounting feet which protrude transversely of the condensing unit. This positioning operation is not easy, since it is necessary to first position the supports, then measure the center distance between the holes of the mounting feet, then position the threaded stems of the bolts, and finally lift the condensing unit and insert the threaded stems in the holes of the feet. This operation is not always easy, since a slight difference in the position of the threaded stems is sufficient to cause difficulty in installation; accordingly, it is necessary to have for example two operators, so that each operator checks from his side the arrangement of the threaded stems at the respective holes of the adjacent mounting foot of the condensing unit. Moreover, in this known type of support it is necessary to fix the condensing unit to the supports by moving the condensing unit back and forth so as to arrange it at a preset distance, for example from an adjacent wall. These known supports further have open ends; this requires subsequent closure of such ends with appropriate plugs, which are supplied separately. This, too, is a problem, since in order to contain costs some installers do not supply the plugs, consequently making the supports unsightly and allowing the nesting of insects, such as wasps, in the cellular structure. It is also known to use injection-molded supports which are shaped like parallelepipeds and are closed at their ends. This solution solves the problem of closure plugs, but entails locking the condensing unit by using self-tapping screws which do not ensure sturdy mounting. Moreover, it would be unthinkable to provide holes in such supports in order to use nuts and bolts, since besides requiring the exact measurements of the position of the holes provided in the feet at the axis of the condensing unit it would also be necessary to turn such unit upside down in order to tighten the nut. The aim of the present invention is therefore to solve the mentioned problems and eliminate the drawbacks of the cited known art by providing a support which allows quick and easy positioning of the perforated feet of a condensing unit as well as rapid and optimum locking thereof. Within this aim, an object of the invention is to provide a support for condensing units which allows, for any model of condensing unit associable therewith, a correct positioning in the sense of distance of the rear part of said condensing unit from an adjacent wall. Another object is to provide a support for condensing units which has vibration-damping properties, is resistant to high temperature, has a high load-bearing capacity, is aesthetically pleasant and cannot be used as a nest by insects such as bees or wasps. Another object is to provide a support for condensing units which is structurally simple and has low manufacturing costs. This aim and these and other objects which will become better apparent hereinafter are achieved by a support particularly for condensing units, comprising a box-like body characterized in that it has, on the opposite side with respect to the side that rests on the ground, a first base provided with a hole at which a fixing means is arranged on the underside, and a second base provided with an axial slot for slidingly locking the head of the fixing means. Further characteristics and advantages of the support according to the invention will become better apparent from the detailed description of a particular embodiment thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein: Figure 1 is an perspective side elevation view of the support according to the invention; Figure 2 is a view of the support, similar to Figure 1, but from below; Figure 3 is a top plan view of the support; Figure 4 is a sectional view, taken along the line IV-IV of Figure 3; Figure 5 is a sectional view, taken along the line V-V of Figure 4; Figure 6 is a view of a detail of Figure 5. With reference to the figures, the numeral 1 designates a support particularly for supporting a condensing unit. The support is constituted by a box-like body 2 made of plastics which is substantially shaped like a parallelepiped and has a trapezoidal cross-section; the box-like body 2 is hollow, and at a lower peripheral edge 3 thereof a flat rim 4 is provided to improve its ground resting stability. On the opposite side with respect to the lower peripheral edge 3, the box-like body 2 has, at its lateral ends, a first flat base 5 and a second flat base 6 which respectively have first fixed locking means 7 and second adjustable locking means 8 for suitable feet which protrude below a condensing unit. A hole 9 is formed at the first flat base 5, and a fixing means, for example a nut 10, is associated at the hole on the internal surface of the first flat base 5; the nut is conveniently associated by way of adapted wings 11, optionally of the flexible and/or self-locking type, which protrude below the first flat base 5 in a region being adjacent to the hole 9. Alternatively, the nut 10 can be molded directly in the plastic material during the production of the box-like body 2. An axial slot 12 is instead formed at the second flat base 6 and allows to position, so as to permit longitudinal sliding and locking at right angles to the second flat base 6, the head 13 of a bolt 14 which can be removably inserted in said slot. The slot 12 is obtained starting from the lateral edge 15 of the box-like body 2 that is adjacent to the second flat base 6. The slot 12 is connected to an adapted seat 16 formed under the second flat base 6; seat 16 has a substantially T-shaped cross-section which allows to slidingly position the head 13 and allows the stem 17 of the bolt 14 to protrude while preventing the extraction of the bolt 14 along an axis which is perpendicular to the second flat base 6. Alternatively, a nut can be arranged in the slot 12; likewise, a bolt can be arranged at the hole 9. Advantageously, the seat 16 is obtained during the molding step of the box-like body 2 and is therefore surrounded by plastic material which does not connect it to the inside of the box-like body 2. The box-like body 2 is further provided internally with adapted strengthening wings 18 arranged longitudinally to the first and second flat bases. Use of the support according to the invention is therefore as follows: the installer places a pair of supports on the ground at a suitable distance, for example, from an adjacent wall, without checking beforehand the center distance between adapted holes formed at the feet provided under the condensing unit. Advantageously, the support is arranged so that the slot 12 is directed toward said wall. The presence of the hole 9 and of the corresponding nut 10 clearly indicates a required front point for fixing the condensing unit; therefore, regardless of the thickness of any model of condensing unit, such thickness only varies the extent of the space to the rear between the condensing unit and the wall, thus considerably improving the front visual aesthetics of the condensing unit. The provision of the slot 12 allows the installer to slide the bolt 14 easily: it is sufficient to slightly tilt the condensing unit so as to make the stem 17 of the bolt 14 match up with an adapted hole provided in the feet that are located below said condensing unit. It has thus been observed that the invention has achieved the intended aim and objects, a support having been provided which allows to achieve rapid, easy and precise positioning of the perforated feet of a condensing unit, these operations being executable even by a single installer. Moreover, optimum and rapid locking of the condensing unit is achieved regardless of the model being used; simultaneously, correct positioning, in the sense of distance from an adjacent wall of the rear part of the condensing unit, is achieved. Finally, a condensing unit is obtained which is aesthetically pleasant, since it is closed perimetrically and is not usable as a nest by insects such as bees or wasps. The materials used, as well as the dimensions of the individual components of the invention, may of course be the most pertinent according to requirements.
