  • DETAILED DESCRIPTION
  • The present invention is generally directed to an apparatus and method for providing a single-size register grill system which can service multiple sizes of register boxes. The present invention is essentially a one-size-fits-all register. It provides a variable opening into the register box which can be configured at installation. Additionally, it may provide for adjustable flow via a series of moveable vanes or shutters which are external to the register box. By placing all these components external to the register box, the size of the register box becomes of less significance. Various terms as used herein are defined below. To the extent a term used in a claim is not defined below, it should be given the broadest definition persons in the pertinent art have given that term, as reflected in printed publications and issued patents. In the description that follows, like parts are marked throughout the specification and drawings with the same number indicator. The drawings may be, but are not necessarily to scale, and the proportions of certain parts have been exaggerated to better illustrate details and features of the invention. One of ordinary skill in the art of a heating, ventilating, and air-conditioning system will appreciate that the embodiments of the invention can and may be used in various types of flow systems. To better understand the novelty of the present invention and the methods of use thereof, reference is hereafter made to the accompanying drawings.
  • FIG. 2 shows a grill funnel 10 which forms a back portion of a grill system 50. Generally, the grill system 50 includes a grill funnel 10 and a grill assembly 20 (see FIG. 5). The grill funnel 10 includes an airflow pathway that is adjustable. The grill funnel 10 is configured to attach a register box (not shown). The grill funnel 10 includes a primary opening 14 (e.g., airflow opening) that is configured to be the airflow pathway through the grill funnel 10. The primary opening 14 is generally sized for a minimum register box dimension for which the grill system 50 may be used. The grill funnel 10 further includes a plurality of secondary openings 15. The secondary 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 the grill funnel 10 to accommodate larger register boxes than the primary 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 mounting holes 16 present around the periphery of the primary 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, the grill funnel 10 may be used with conventional grills which have a user adjustable closure system.
  • FIG. 3 shows the grill 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 the grill funnel 10 to the register box (not shown). For example, if the primary opening 14 was 6×10 inches, then with the inner bypass plugs 12 removed such that the secondary openings 15 are opened, the grill funnel 10 would have an airflow pathway that would be suitable for a larger size such as 6×12 inches.
  • FIG. 4 shows the grill 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 each secondary openings 15. The holes 19 are drilled at specific intervals to allow the connection of grill funnel 10 to the ceiling or wall register box during installation. This allows this example 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 the grill 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 the grill assembly 20 of the grill system 50. The grill assembly 20 is configured to be attached to the grill funnel 10 (see FIG. 1). The grill assembly 20 includes a housing with a series of vertical and horizontal vanes 21, 22 to deflect the airflow uniformly into the room served. In other words, the vanes 21, 22 are configured to direct air flowing through the airflow pathway. Also visible in FIG. 5 is an adjustment knob 25 which may be used to control the airflow through the grill system 50.
  • FIG. 6 a shows the inside of the grill assembly 20. For clarity, the grill funnel is not shown. Mounted on the grill assembly 20 are corresponding airflow adjustment members 23, 24 such as vertical and horizontal shutters which may be used to vary the airflow through the grill assembly 20. The adjustment members 23, 24 are activated by means of the adjustment knob 25 which is operatively connected to the adjustment members 23, 24.
  • FIG. 6 b shows a cross-section view of the grill assembly 20. As shown in FIG. 6 b, the vertical vanes 21 line up with vertical adjustment members 23 to form a means to regulate airflow through the grill assembly 20.
  • FIG. 7 illustrates an enlarged view of the adjustment knob 25. In one embodiment, the adjustment knob 25 is connected to the adjustment members 23, 24 by connection members 27, such as rods, linkages or cable arrangement. One portion of the connection member 27 is attached to the adjustment knob 25, and another portion of the connection member 27 is attached to the adjustment members 23, 24. Rotating the adjustment knob 25 between a first position and a second position causes the connection members 27 to move, and hence each adjustment member 23, 24 to pivot around an end of the adjustment member 23, 24 to open or close off the airflow through the grill assembly 20.
  • FIG. 8 shows an embodiment of the grill system 50 used in conjunction with an optional flow control device 30. An example of a flow control device is described in U.S. Pat. No. 7,347,774. The flow control device 30 is attached to the back of the grill 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 a seal assembly 18 which is attached to the wall or ceiling contacting face of grill 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 the grill funnel 10. Again, in this view the mounting holes 19 are visible. Operationally, the installer selects the holes 19 to match the register box size to which the grill assembly is affixed (not shown). In one embodiment, the grill system 50 extends from an end of the register box.
  • FIG. 9 illustrates a grill system 60 in accordance with one embodiment of the invention. For convenience, the components in the grill system 60 that are similar to the components in the grill system 50 will be labeled with the same number indicator. The grill system 60 includes the grill assembly 20 and the grill funnel 10. The grill system 60 optionally may include the flow control device 30. In this embodiment, the vanes 21 are separated by a divider 31. As shown in FIG. 9, the divider 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 in FIG. 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 in FIG. 9, the face of the grill is divided into three airflow directions, and the angle of the separation 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.
