Definitions

  • This invention relates to a protective device for the glass pane of an open hearth fireplace, and more particularly, to a protective device capable of screening said glass pane from the action of the fire in the fireplace.
  • open hearth fireplaces i.e. fireplaces wherein the flame is fully exposed to view and even directly under reach, serve an unreplaceable function, both from a practical and psychological standpoint, owing to the warm feeling or atmosphere that they create.
  • glass panes or clear closures have been proposed which can be placed on the hearth of the fireplace such as to hinder the flow of air from the room into the flue without impairing the view and access to the fire itself.
  • these glass panes comprise one or more plates of tempered glass, which are perfectly clear and heat resistant, connected to the masonry portion of the fireplace such as to be readily raisable, rotatable and removable whenever wood is to be added or adjusted for combustion.
  • the task of this invention is to provide a protective device for fireplace glass panes, which can obviate the shortcomings mentioned hereinabove.
  • a protective device for the glass pane of an open hearth fireplace which comprises at least one clear plate removably engaged with the fireplace aperture, also comprises means effective to convey air parallel to and in close contact with the surface of said plate facing the fireplace interior.
  • said means comprise interspaces shaped as to direct laminar airflows closely along the inner surface of said plate, the air flowing through said shaped interspaces being delivered to the space or room where the fireplace is installed owing to the draft effect of the flue.
  • the protective device according to this invention can be applied to any types of glass panes and fireplace since it is characterized in that means are provided for conveying air in close contact with, or sweeping, the clear surfaces to be protected, and it will be appreciated that such means may be variously constructed, with either natural or forced air circulation, and can be installed directly at the glass pane, or internally, or on the fireplace masonry work.
  • the preferred embodiment is that shown in the drawing figures, and contemplates that the air conveying means utilizes the flue natural draft, and that the device is incorporated to the glass pane, without involving the fireplace masonry.
  • a fireplace 1 has a glass pane 2 spanning the entire fireplace width and arranged to be movable relatively to the fireplace 1 by means of control means known per se and adapted, for example, to rotate the glass pane and lift it upwards.
  • means are provided effective to convey air in close contact with the clear plate 3 of the glass pane, made for example from tempered glass or the like, said means comprising shaped interspaces 4 which extend parallel to the edges of the plate 3 and are so configured as to direct laminar flows of air along said plate 3.
  • the plate 3 is surrounded and supported by a framework 5, whereat the interspaces 4 are formed, as shown particularly in Figures 2 and 3.
  • the framework 5 comprises, in fact, and as shown in Figure 2, a first frame 5a and second frame 5b; the first frame 5a can be engaged in substantially airtight relationship with the walls la of the fireplace 1 which border the hearth, and embraces the second frame 5b, in turn surrounding the plate 3. Between the first and second frames, 5a and 5b, there are inserted spacer elements 6 which define the width of the shaped interspaces 4.
  • the first frame 5a extends prevailingly within the fireplace, thus directing the airflow admitted into the interspace 4 parallel to the plate 3.
  • first frame 5a may have a folded . edge 7 facing the inner surface of the plate 3 to the fireplace 1. This folded edge defines in practice an air guiding region forming a nozzle-like member convergent toward the plate 3.
  • the framework 5 shown in Figure 3 is largely similar to the one shown in Figure 2, except that the second frame 5b is missing; in this case, the first frame 5a directly supports the plate 3, through the spacer elements 6.
  • the plate 3 is shown in the drawings as being a single piece construction, but it will be appreciated that several coplanar elements may also be provided to make up the plate 3, and each of these elements may also be removable separately from the adjacent ones. In this case, i.e. with a composite construction plate 3, it may be advisable, according to the invention, to provide shaped interspaces also between each plate 3 portions, such as by interposing between contiguous plates T-like elements slightly spaced apart from the plates and arranged to convey air from the surroundings toward the inner surface of each plate portion.
  • the protective device of this invention operates as follows.
  • the invention achieves its objects.
  • a protective device has been in fact provided which also lends itself for extremely simplified and economical applications, such as the ones illustrated, and may be incorporated to any types of existing fireplaces. Moreover, the protective device of this invention is highly effective in operation because its action becomes more powerful the higher grows the flame on the hearth and the stronger the draft through the flue, that is the more its protective action becomes useful.
  • the device according to the invention provides an airflow which has exactly the opposite effect to those obtainable from a turbulent airflow led into the flue through an aperture having no specific shape.
  • any draft induced in the room and directed to flow air toward the flame and flue would create in the region of the fireplace eddies which also entrain an amount of air mixed with ash particles from the hearth, which results in the formation of tarry deposits at the very areas where turbulent air is admitted, which deposits would quickly affect the plate 3 clearness and blacken it, thus interfering with the radiation of heat as well as with the viewing of the flame.
  • the streamlined airflows created by the device according to this invention flow in close contact with the plate 3 and protect it against the action of heat and tarry deposits by preventing any turbulence.
  • the shaped interspace may be provided at various locations in the fireplace, and the means for conveying the air parallel to the plate may be based upon the principle of air being drawn naturally into the flue under the draft action of the latter and/or provide for a forced draft, e.g. by means of blowers.
  • the materials used and the dimensions may be any suitable ones for a specifically selected application.
