Abstract
An air register is described in which top and bottom panels are disposed to opposed sides of a central grid. The grid includes at least one open ended cell formed by wall members that extending between the top and bottom panels. The top panel includes a top opening in open communication with the cell and adjacent one wall member of the grid. The bottom panel includes a bottom opening in open communication with the cell adjacent another wall member of the grid.
Description
- This application is an originally filed U.S. Patent application and bears no relation to any previously filed domestic or foreign application, patent, registration, utility model, provisional application, or publication.
- The present invention relates to direction of airflow through an air register.
- Hot and cold air registers are used to disperse flowing air into rooms or adjacent environments. Some are made to direct a substantially laminar flow in one direction, others are designed to disperse the airflow in multiple directions. Most, however, release streams of air that create drafts in the adjacent areas. Drafts develop when the register includes louvers or other air guiding devices that allow substantially laminar flow from the pressure side of the associated register.
- Some registers include multiple directional louvers or guides that are intended to produce multiple airflow columns in desired directions. However the louvers themselves typically remain fairly consistently shaped. One common louver shape is simply flat, planar blades that are parallel to one another and spaced apart to allow airflow, with direction imparted by the louver angular orientation.
- Other forms of registers may include arcuate louvers that produce a similarly arcuate airflow. Depending upon the degree of bend formed in the louvers, a certain amount of turbulence is created after the air leaves the register. Such turbulence results in mixing of the forced air with ambient air. This is desirable when even warm or cool air distribution is desirable. However, arcuate louvers are costly to form.
- A need therefore has remained for an air distribution register that will effectively discharge air in desired directions, and that will initiate turbulence without requiring arcuate louvers.
- Preferred embodiments of the invention are described below with reference to the following accompanying drawings.
- FIG. 1 is a perspective view of a preferred form of air register;
- FIG. 2 is an exploded perspective view of the exemplary register;
- FIG. 3 is an enlarged sectional view taken substantially along line3-3 in FIG. 1;
- FIG. 4 is an enlarged fragmented view of the area enclosed within the dashed circle identified by the
numeral 4 in FIG. 3, only showing exemplary exit airflow; - FIG. 5 is a top plan view; and
- FIG. 6 is a bottom plan view.
- This disclosure of the invention is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws “to promote the progress of science and useful arts” (Article 1, Section 8).
- Before describing exemplary elements of the preferred embodiments in detail, general aspects of the invention will first be discussed.
- In one aspect of the invention, the
air register 10 includes atop panel 12 having atop surface 13 and anopposed bottom surface 14.Top openings 15 in thepanel 12 extend between the top andbottom surfaces air transmission grid 18 with top andbottom grid surfaces individual cells 19 formed bycell walls grid 18 is joined to thebottom surface 14 of thetop panel 12 such that at least some of thecells 19 open into thetop openings 15. Abottom panel 24 has anupper surface 25 and an opposedlower surface 26 andbottom openings 27 that extend between the upper andlower surfaces bottom panel 24 is joined to thegrid 18 along thebottom grid surface 21. The bottom and top openings are offset to opposed sides of associated cells. - In another aspect, the
register 10 is comprised of a laminated body including top andbottom panels central grid 18. The grid includeswall members bottom panels ended cell 19. Thetop panel 12 includes a top opening 15 in open communication with thecell 19 adjacent onewall member 22 of thegrid 18 and thebottom panel 24 includes a bottom opening 27 in open communication with thecell 19 adjacent anotherwall member 22 of thegrid 18. - In the above aspects, the described structures are arranged to be placed in a forced air stream, such that the moving air will pass from the top panel, through the
top openings 15, into the associatedcells 19, and finally out through thebottom openings 27. Due to the offset nature of the top andbottom openings cell walls openings - It should also be noted that the
preferred register 10 may be constructed in numerous sizes to accommodate various air flow situations. For example, preferred forms of theregister 10 may be used as an air discharge or return, in heating and ventilating construction or other areas where it is desirable to mix and distribute forced air with surrounding ambient air. - The registers may be used in horizontal orientations such as within ceiling mounted fixtures, in vertical orientations such as in wall mounted fixtures, or in other angular orientations. Thus, the terms “top, bottom, upper and lower” should be understood broadly to include such other orientations.
- The preferred top and
bottom panels respective openings grid cell 19 therebetween. The panels and grid may be formed of a metal such as aluminum, or may be other materials such as an appropriate plastic, according to the needs of the user. - It may also be noted that the
openings 15 may be oriented in various angular pattern arrangements. This may be done to facilitate dispersion of the airstream in several directions. In most cases, the desired air discharge will be in a direction away from theregister 10. On the other hand, aregister 10 with one or more sets ofopenings 15, 27 (such as illustrated) may be used to provide discharge in more multiple directions. - In preferred forms, the
openings individual cells 19 along thegrid 18. The width and length dimensions of thevarious openings adjacent cells 19 in thegrid 18. The exemplary arrangement illustrated in the sectional views of FIGS. 3 and 4 may be accomplished uniformly across the register. Such spacing is desired to be such that thetop openings 15 will be situated adjacent one set of associatedwalls 22 of the adjacent cells, while the bottom opening 27 will be situated adjacent to an opposite set of the grid walls. Thus, the openings are staggered as may be understood by viewing FIG. 4. -
Walls 23 of the grid divide the areas between theopenings walls 23 confine air passed through individual cells to aid in creation of turbulence. - Also from an examination of FIG. 4, it may be understood that the cells are substantially rectangular. In the illustrated example, the cells are substantially square with a common side dimension. Whether the cells are rectangular, including square, or other rectilinear shape, a dimension across the opening on
opposed surfaces 20, 21 (FIG. 2) thereof are preferred to be greater than the corresponding width dimensions than theopenings openings - The
grid 18 is preferably comprised of a plurality of intermeshed or interleaved sheets that, together, form a matrix of substantially identical individual open-endedcells 19. The grid may be formed by conventional means and be sized according to need, but is preferred to remain in the above described relation to theopenings - One preferred connection for securing the two
panels grid 18 together is afforded by a mechanical appliance such as provided by the exemplified joiningbrackets 30. Thebrackets 30 are shown merely as an example of a configuration that will secure the top andbottom panels tabs 31 may be provided on thetop plate 12 and substantiallyidentical tabs 32 may be provided on thebottom plate 24. Thebrackets 30 may includeappropriate slots respective tabs - It is pointed out that other bracket or mounting arrangements may be made, including a frame-type perimeter that could be made simply by providing the brackets of length dimensions substantially equal to the corresponding dimensions of the register. Other mounting arrangements including spot-welding, fasteners or other arrangements may also be used for effectively securing the top and bottom panels over the
central grid 18. However, the preferred connection is mechanical to enable dismantling the register for cleaning. - It is preferred that the
walls plates panels - The orientation and relationship of the
openings walls - In compliance with the statute, the invention has been described in language more or less specific as to structural and methodical features. It is to be understood, however, that the invention is not limited to the specific features shown and described, since the means herein disclosed comprise preferred forms of putting the invention into effect. The invention is, therefore, claimed in any of its forms or modifications within the proper scope of the appended claims appropriately interpreted in accordance with the doctrine of equivalents.
