FIG. 2 shows agrill funnel 10 which forms a back portion of agrill system 50. Generally, thegrill system 50 includes agrill funnel 10 and a grill assembly 20 (seeFIG. 5 ). Thegrill funnel 10 includes an airflow pathway that is adjustable. Thegrill funnel 10 is configured to attach a register box (not shown). Thegrill funnel 10 includes a primary opening 14 (e.g., airflow opening) that is configured to be the airflow pathway through thegrill funnel 10. Theprimary opening 14 is generally sized for a minimum register box dimension for which thegrill system 50 may be used. Thegrill funnel 10 further includes a plurality ofsecondary openings 15. Thesecondary openings 15 are closed by inner and outer bypass plugs 11, 12 which may be removed to increase the size of the airflow pathway through thegrill funnel 10 to accommodate larger register boxes than theprimary opening 14. The bypass plugs 11, 12 may be made from an elastomeric material or a composite material. - The
grill funnel 10 includes a series of mountingholes 16 present around the periphery of theprimary opening 14 which may be used to mount an optional automated flow control units as described in U.S. Pat. No. 7,347,774, which is incorporated herein by reference. In another embodiment, thegrill funnel 10 may be used with conventional grills which have a user adjustable closure system. -
FIG. 3 shows thegrill funnel 10 with several inner bypass plugs 12 removed. The removal of the inner bypass plugs 12 effectively increases the size of the airflow pathway (e.g., opening) between thegrill funnel 10 to the register box (not shown). For example, if theprimary opening 14 was 6×10 inches, then with the inner bypass plugs 12 removed such that thesecondary openings 15 are opened, thegrill funnel 10 would have an airflow pathway that would be suitable for a larger size such as 6×12 inches. -
FIG. 4 shows thegrill funnel 10 with the bypass plugs 11, 12 removed. As a result, the effective opening (e.g., airflow pathway) to the register box is enlarged by exposing eachsecondary openings 15. Theholes 19 are drilled at specific intervals to allow the connection ofgrill funnel 10 to the ceiling or wall register box during installation. This allows thisexample grill funnel 10 to service register boxes from 6×10 through 6×14. The example of removable bypass plugs is only one way in which to vary the effective opening of thegrill funnel 10. Alternate embodiments include but are not limited to sliding doors, roll up gates, folding gates (accordion style), pre-molded punch out plugs, etc. -
FIG. 5 shows the front view of thegrill assembly 20 of thegrill system 50. Thegrill assembly 20 is configured to be attached to the grill funnel 10 (seeFIG. 1 ). Thegrill assembly 20 includes a housing with a series of vertical andhorizontal vanes vanes FIG. 5 is anadjustment knob 25 which may be used to control the airflow through thegrill system 50. -
FIG. 6 a shows the inside of thegrill assembly 20. For clarity, the grill funnel is not shown. Mounted on thegrill assembly 20 are correspondingairflow adjustment members grill assembly 20. Theadjustment members adjustment knob 25 which is operatively connected to theadjustment members -
FIG. 6 b shows a cross-section view of thegrill assembly 20. As shown inFIG. 6 b, thevertical vanes 21 line up withvertical adjustment members 23 to form a means to regulate airflow through thegrill assembly 20. -
FIG. 7 illustrates an enlarged view of theadjustment knob 25. In one embodiment, theadjustment knob 25 is connected to theadjustment members connection members 27, such as rods, linkages or cable arrangement. One portion of theconnection member 27 is attached to theadjustment knob 25, and another portion of theconnection member 27 is attached to theadjustment members adjustment knob 25 between a first position and a second position causes theconnection members 27 to move, and hence eachadjustment member adjustment member grill assembly 20. -
FIG. 8 shows an embodiment of thegrill system 50 used in conjunction with an optionalflow control device 30. An example of a flow control device is described in U.S. Pat. No. 7,347,774. Theflow control device 30 is attached to the back of thegrill funnel 10 by attachment members (not shown), such as screws. The removable bypass plugs have been removed in this view. In operation, one might remove these to reduce the amount of airflow through the flow control unit should excessive airflow be present and the airflow control unit is smaller than the register box to which it is to be inserted. In this manner it is possible to service a wide range of register boxes and airflow rates with a limited number of sizes of grill assemblies and airflow control units. Also shown in this view is aseal assembly 18 which is attached to the wall or ceiling contacting face ofgrill funnel 10. This serves to seal the airflow and prevent flow-out from the edges of the grill assembly which can discolor a wall or ceiling over time. Alternately, the seal assembly may be held in a groove formed into thegrill funnel 10. Again, in this view the mounting holes 19 are visible. Operationally, the installer selects theholes 19 to match the register box size to which the grill assembly is affixed (not shown). In one embodiment, thegrill system 50 extends from an end of the register box. -
FIG. 9 illustrates agrill system 60 in accordance with one embodiment of the invention. For convenience, the components in thegrill system 60 that are similar to the components in thegrill system 50 will be labeled with the same number indicator. Thegrill system 60 includes thegrill assembly 20 and thegrill funnel 10. Thegrill system 60 optionally may include theflow control device 30. In this embodiment, thevanes 21 are separated by adivider 31. As shown inFIG. 9 , thedivider 31 is positioned at an angle relative to the sides of the grill assembly. In the case of a smaller register box, the horizontal and vertical grill vane structure, as shown inFIG. 5 , may not be as effective in distributing air into the room because the lateral vanes may not be in the main airflow. In the embodiment shown inFIG. 9 , the face of the grill is divided into three airflow directions, and the angle of theseparation divider 31 is designed to give a more uniform flow in all three directions without regard to the register box size or the number of bypass plugs removed. - Although the descriptions above contain many specifications, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the embodiments of this present invention. Persons skilled in the art will understand that the method and apparatus described herein may be practiced, including but not limited to, the embodiments described. Further, it should be understood that the invention is not to be unduly limited to the foregoing, which has been set forth for illustrative purposes. Various modifications and alternatives will be apparent to those skilled in the art without departing from the true scope of the invention, as defined in the following claims. While there have been illustrated and described particular embodiments of the present invention, it will be appreciated that numerous changes and modifications will occur to those skilled in the art, and it is intended in the appended claims to cover those changes and modifications which fall within the true spirit and scope of the present invention.
- While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
