Definitions

  • the present invention relates to an adapter device for connecting a radiator element to a plumbing system.
  • the heating radiators employed for the heating of buildings consisting usually of a battery of side-by-side radiator elements, are supplied with a hot fluid (typically water) circulating in a plumbing system formed by a network of pipes.
  • a hot fluid typically water
  • Each radiator has an inlet opening and an outlet opening, typically arranged on a lateral side of an end radiator element .
  • the plumbing system comprises a delivery pipe and a return pipe, to which the radiator is connected through suitable connectors.
  • the pipes of the plumbing system protrude from a wall of the room wherein the radiator must be installed and the radiator is designed with side inlet and outlet openings, so as to easily connect to said pipes.
  • the pipes intended to be connected to the radiator protrude from the floor.
  • the radiator to be used must be especially designed, or at least be modified, in order to be connected to the pipes from below; therefore radiators equipped with downwardly facing attachments are needed; however, additional components and pipelines are commonly required for connecting the pipes of the plumbing system to the inlet and outlet openings of the 5 radiator.
  • Adapting devices are also known that allow using a radiator with side attachments even in the presence of delivery and return pipes protruding from the floor; known adaptation 10 devices do not seem, however, fully satisfactory, especially in terms of construction simplicity, effectiveness, dimensions and ease of assembly.
  • the present invention therefore relates to an adapter device for connecting a radiator element to a plumbing system as defined in essential terms in the appended claim 1 and, in its additional features, in the dependent claims.
  • the device of the invention allows adapting a radiator element, designed and made to form a side connecting radiator enabling it to form a radiator to be connected from below.
  • the device of the invention allows to adapt the radiator, especially in the case of an aluminum radiator, to plumbing systems with delivery and return pipes with predetermined fixed pitch, which in the most common applications is typically 50 mm, without requiring an increase of the pitch and allowing to cross delivery and return flow 5 (in the standard common application, the delivery pipe is the inner one with respect to the radiator, while the aluminum radiator necessarily requires a delivery flow from the outer pipe) .
  • the device of the invention is also simple to make and mount on the radiator element.
  • FIG. 1 is a partial schematic exploded perspective view of a radiator element provided with an adapter device according
  • FIG. 2 is a longitudinal sectional view of the radiator element of figure 1;
  • FIGS. 3 and 4 are respectively a plan view from below and a side elevation view on an enlarged scale and with parts
