Definitions

  • This invention relates generally to outdoor heating devices and, more specifically, to a Patio Heater Side Heat Director.
  • FIG. 1 is a perspective view of a conventional (tabletop) patio heater 10.
  • the patio heater 10 has a base 12, within which the propane cylinder is contained.
  • a stern 14 extends upwardly from the base 12 to the burner 16.
  • the propane flow ⁇ passes through the stem 14 to supply the burner 16 with fuel.
  • the burner 16 is topped by a heat shield 18, and surrounded by a guard 20.
  • the heat shield 24 is defined by a circular (typically) perimeter edge 24, and is removably attached to the burner 16 by a securing nut 22 (or by some other fastening system). While the conventional patio heater 10 is very handy to increase personal comfort while entertaining or otherwise spending time outdoors, it does suffer from a problem related to its limited fuel source.
  • the patio heater side heat director attachment should be attachable to a conventional patio heater so that the dome attachment hangs down from the heater's beat shield on one side.
  • the side heat director should reflect incident heat/energy on one side of the heater towards the opposing side of the heater.
  • the side heat director should define two or more lobes that assist in focusing the energy reflected by the director.
  • the side heat director should be easily attachable to a conventional patio heater, such as by clipping or crimping the heat director to the edge of the patio heater heat shield.
  • the side heat director attachment should embody a very low thermal mass so that very little energy is retained by the side heat director attachment, such that the greatest amount of heater energy possible is reflected towards the seating area.
  • Figure 1 is a perspective view of a conventional tabletop patio heater
  • Figure 2 is a side perspective view of the heater of Figure 1 , having a preferred embodiment of the side heat director of fhe present invention attached thereto
  • Figures 3 A and 3B are partial cutaway views of the attachment section of the side heat director of Figure 2 attached to the heater heat shield of Figure 1 ;
  • Figure 4 is a front perspective view of the heater and side heat director attachment of Figure 2;
  • Figure 5 is a front view of the side heat director attachment of Figures 2 and 3 ;
  • Figure 6 is a top view of the heater of Figure 1 having the side heat director attachment of the present invention attached thereto.
  • Figure 2 is a side perspective view of the heater 10 of Figure 1, having a preferred embodiment of the side heat director 30 of the present invention attached thereto.
  • the side heat director 30 is a lightweight, easily-attachable metallic reflector that reflects infrared energy emitted from a side (presumably a backside) of the burner 16, so that that energy is directed towards a seating area.
  • Figure 4 provides additional detail regarding the attachment 30.
  • the isolation views provided in Figures 3 A and 3B depict that the attachment
  • FIG. 30 has a ridge 31 that forms either a narrow pocket 33 A or an offset pocket 33B around its upper perimeter.
  • a plurality of the pockets 33 A and 33B make up the preferred way for the side heat director 30 to attach to the heat shield (see Figure 1), as is discussed in more detail below in connection with Figure 6.
  • pleats 35 may be formed in various portions of the attachment 30. These pleats 35 (where included) are configured and located to create generally spherical "lobes" in the attachment 30, without the need for sophisticated metal forming procedures in manufacturing of the attachment 30.
  • the pleats 35 are optional where a lower-cost manufacturing process is desirable. In other versions, for aesthetic or efficiency reasons (or others), the pleats 35 could be eliminated by molding or pressing the curved shape into the attachment 30.
  • Figure 4 is a front perspective view of the heater and side heat director attachment 30 of Figure 2.
  • the attachment 30 is designed to provide the maximum heat reflection while also taking care to not damage the structure of the patio heater 10.
  • the preferred design shape, therefore, is the dual-lobed shaped shown here in Figure 3.
  • the left lobe 32 and right lobe 34 extend from the left and right side of the shield 18.
  • the lobes 32, 34 meet at a central section of the attachment 30 (behind the burner 16), that has a bottom edge that is slightly raised (approximately 15 angular degrees) so that heat will not be reflected onto the stem 14. The result is to reflect the maximum energy into and around the sides of the burner 16, towards the seating area adjacent to the heater 10. It is a simple matter of rotating the heater 10 so that the heat is directed towards the desired user location.
  • Figure 5 shows the attachment 30 detached from the heater.
  • the left lobe 32 and right lobe 34 meet in the central portion of the attachment 30 at the central ridge 38.
  • the ridge 38 functions to protect the stem (see Figure 4) from exposure to excess reflected heat, and further directs most of the reflected energy out through one of the two lobes 32, 34.
  • the upper edge 36 of the attachment 30 is configured so that it will cooperate with the perimeter edge of the patio heater heat shield (see Figure 1).
  • the attachment 30 is designed to be clipped or crimped to the heat shield (see Figure 1) so that it will be securely attached without too much added thermal mass (i.e. without large metallic devices).
  • Figure 6 depicts how the arrangement appears from another angle.
  • the lower edges (3 IA and 31B 5 respectively) of the left lobe 32 and right lobe 34 are curved in such a way as to each create a generally spherical reflective surface facing the patio burner (see Figure 1).
  • the optional seam 27 shown here is intended to depict the potential that the attachment 30 be composed of two individual halves. Making it two-piece may facilitate the packaging and shipping of the attachment 30. The two halves would be interconnected at the seam 27 and central ridge 38.
  • FIG 6 is a top view of the heater 10 of Figure 1 having the side heat director attachment 30 of the present invention attached thereto.
  • the upper edge 36 of the heat director attachment 30 actually folds up over the perimeter edge 24 of the heat shield 18 until it is atop the shield 18 as shown here.
  • Simply crimping the attachment 30 to the heat shield 18 will usually be sufficient to hold the attachment 30 in place, but simple all-metal clips (even paper clips) could be added to hold the attachment 30 in place even more securely.
  • the perimeter edge is circular in profile, a series of notches alternate with tabs that form either narrow pockets 33A or offset pockets 33B.
  • the tabs do not have to form either one or the either type of pocket 33A and 33B, as depicted above, but rather could be variations of both. That is to say that the pockets 33 A, 33B could begin at the center of the heat shield 18 (top of the page here) as strictly narrow pockets 33 A, and then proceed to transition to a more and more offset until reaching the configuration shown above in Figure 3B.
  • the purpose of the offset is to cause the attachment 30 to have more curvature at its outer edges than at its center by causing the upper edge 36 of the attachment 30 to be more "pulled up" at its outer edges.
  • the attachment 30 is made from a very thin sheet of altt ⁇ inum material (e.g. between approximately 0.006 and 0.050 inches in thickness — or heavy gauge foil).
  • the purpose of using very thin material is to minimize the thermal mass of the attachment 30. If the thermal mass is very low, then the attachment 30 will reflect radiated energy without retaining heat, thereby creating another radiant heat source and increasing the heat radiating Horn the element as well.
  • Durability or aesthetic qualities can also be enhanced by utilizing a multi- layered material for the attachment 30.
  • a multiple layered material will tend to be more rigid than a single thin layer of material, and will provide decorative options, such as the ability to emboss logos and other designs into the attachment 30. While such options are available in a limited fashion in the single-layer version of attachment 30, (here would be additional options for the multi-layered construction.

Abstract

La présente invention a trait à un dispositif latéral d’orientation de chaleur de radiateur de terrasse. Le dispositif adaptable du dispositif latéral d’orientation de chaleur de radiateur de terrasse peut être fixé à un radiateur de terrasse classique de manière à ce que le dispositif adaptable en forme de dôme soit suspendu à l’écran thermique du dispositif de chauffage sur un côté. Le dispositif latéral d’orientation de chaleur est conçu de manière à réfléchir la chaleur/l’énergie incidente sur un côté du dispositif de chauffage vers le côté opposé du dispositif de chauffage. Le dispositif latéral d’orientation de chaleur définit deux lobes ou plus qui permettent de concentrer l’énergie réfléchie par le dispositif d’orientation. Le dispositif latéral d’orientation de chaleur peut être facilement fixé à un radiateur de terrasse classique en attachant ou en pinçant le dispositif d’orientation de chaleur au bord de l’écran thermique du radiateur de terrasse. Enfin, le dispositif adaptable du dispositif d’orientation de chaleur latéral a une masse thermique très faible de manière à ce que très peu d’énergie thermique soit retenue par le dispositif adaptable du dispositif latéral d’orientation de chaleur, de sorte que le pourcentage le plus important possible de l’énergie du dispositif de chauffage soit réfléchi vers la zone de places assises.
