10 Claims, 9 Drawing Figures PKTENTEDMAY 16 m2 SHEET 2 [IF 2 PRIOR ART ATTORNEYS BEZEL INNER GUIDE FRAME BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to bezel structures such as are employed in fluid distribution systems like automotive air conditioning systems.
2. Description of the Prior Art A wide variety of discharge louvers and control panels are currently in use in automotive air conditioning systems. Each type has heretofore required a custom bezel structure. For example, different bezels were required for the dual louver outlets, for the triple louver outlets, and for the quadruple louver outlets. It has, ordinarily, not been necessary to employ more than four louvers in any given outlet to effect the desired distribution of air toward the sides as well as toward the central passengers.
In addition, one set of different bezels were required if a control panel was mounted on the left of the bezel structure, a different set of bezels were required if a control panel was mounted on the right hand side of the bezel, and still a different set of bezels were required if the control panel was mounted in the center. Thus, a large and objectionable inventory of bezels was required to allow the necessary flexibility in effecting the various designs of discharge louvers and control panels required for the difierent automobiles.
Additionally, the prior art type bezel structures had structural recesses that induced eddy currents and turbulence that adversely affected the flow pattern of the discharged fluid such as cold air.
Furthermore, the prior art type bezel structures required a multiplicity of fasteners for supporting each of the louvers and the control panel; requiring additional inventory, as well as additional time and expense in assemblying the louvers and the control panel within the bezel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS It is an object of this invention to provide a universal bezel structure that allows wide flexibility in effecting any final design and obviates the disadvantages of the prior art structures requiring a different and respective bezel for each design.
It also is an object of this invention to provide a bezel structure that eliminates eddy currents and turbulence that adversely afiected the flow patterns of the discharged fluid from the prior art type bezel structures and, instead, provides an internal flow profile that is streamlined and effects a better flow of the fluid being distributed with less power requirements.
It is an object of this invention to provide a bezel structure accomplishing the foregoing objects and employing readily assemblable structures that may be snapped into place without requiring additional fastening means.
Referring to FIGS. 1-5, various embodiments of final designs of bezel 11, discharge louvers 13, and control panel 15 are illustrated. FIG. 1 illustrates four discharge louvers 13 and a control panel 15 mounted at the left within the louver structure 11. FIG. 2 illustrates three discharge louvers 13a with the control panel 15 mounted at the left. FIG. 3 illustrated two discharge louvers 13b with the control panel 15 mounted at the left. FIG. 4 illustrates an embodiment in which the louvers 13 are evenly spaced on both sides of a centrally mounted control panel 15 within bezel 11. A single louver like louvers 13b may be employed on each side instead of the dual louvers 13 in the embodiment of FIG. 4 if desired. FIG. 5 illustrates the embodiment of FIG. 1 in which the control panel 15 is mounted on the right hand side of the louvers l3 and bezel l l. The embodiment of FIG. 5 may be effected simply by rotating the embodiment of FIG. 1 through 180 to move the control panel from the left hand side to the right hand side. Each of the embodiment of FIGS. 1-3 may be converted to have the control panel 15 mounted on the right hand side by similarly rotating through I". Suitable controls, typified by control knobs 17, are installed in a conventional way for all embodiments.
The improved bezel structure of this invention makes possible all of the foregoing discharge louver designs, both explicit and implicit. It is illustrated in exploded form in FIG. 6. Therein, bezel 11 comprises an outer frame 19 and an inner guide frame 21. The outer frame 19 is adapted for connection with a plenum in the fluid distribution system, as by apertures 23 for receiving a suitable fastener means such as a sheet metal screw.
The inner guide frame 21 is adapted to fit within the outer frame 19. The inner guide frame 21 has a plurality of stations, or mounting positions, for mounting a plurality of louvers within the outer frame. The stations are illustrated by matched receptacle means such as respective pairs of matched apertures 25. The plurality of stations comprise a plurality of sets of stations, each set of stations, in turn, comprising at least a pair of stations so spaced as to mount a louver within the outer guide frame. The plurality of stations also comprise a pair of stations for mounting a control panel within the outer frame. The oppositely disposed sides of the inner guide frame 21 are identical so that the inner guide frame may be rotated to place the left hand side, or end, on the right hand side, or vice versa.
Referring to the inner guide frame 21, there are 10 stations that are so arranged that eight combinations of design are possible with only three difierent louver sizes, enabling having either two, three, or four louvers per bezel. At each station a support web 27 is provided. Support web 27 has a means for mounting it to both the top and bottom inner guide frame. As illustrated, the means for mounting comprises snap-in appendage means such as protrusions 29 for engaging the respective pair of matched apertures 25. Preferably, each protrusion 29 conformingly engages its correlative apertures 25 on at least two sides. The snap-in protrusions 29 may be snapped manually and readily into the pair of matched apertures 25 to affix the support web 27 to inner guide frame 21 at each station desired.
As can be seen, if support webs 27 are respectively snapped into the matched pair of apertures 25b and the bezel assembled, a structure like the one illustrated in FIG. 3 is effected in which the control panel 15 is on the left hand side and a pair of louvers 13b are disposed on the right hand side. As indicated, if the control panel is desired on the right hand side, the entire assembly is merely rotated 180 to place it on the right hand side before mounting the inner guide frame 21 within the outer frame 19.
Similarly, if three louvers are desired, as illustrated in FIG. 2, the respective support webs are snapped into place in the matched pairs of apertures 25a. The inner guide frame may then be positioned to place the control panel on either the right or the left.
On the other hand, if the control panel is to be emplaced in the center, the support webs will be snapped into apertures 25c. In addition, if dual louvers are to be employed on both sides of the control panel, support webs 27 are snapped into apertures 25d, also.
It is preferred that a simple structure be provided for supporting the respective louvers in their respective support webs. Accordingly, each support web 27 has a snap-in receiving means adjacent its center for receiving a compatible snapin structure supporting the louvers to be mounted therein. Specifically, each of the louvers 13 has a stub shaft 33, FIG. 7, protruding from their ends that are'to be adjacent the support webs 27. The snap-in receiving means comprises a slot means 35 having its entry at the rear of the support web 27, traversing forwardly to a turning location, or knee portion, 37 and then backwardly to a terminal portion 39 adjacent the center of the support web 27. The terminal portion 39 is adapted to conformably and pivotally retain the stub shaft 33 in place. A protrusion 41 is provided intermediate the terminal portion 39 and the knee portion 37 for retaining the stub shaft 33 in place. The distance separation between protrusion 41 and the opposite wall or similar matching protrusion 41 is large enough; or the protrusions are small enough; that the stub shaft 33 can be snapped therepast and into the terminal portion 39. On the other hand, the distance separation between the protrusions 41 is small enough; or the protrusions 41 are large enough; to prevent inadvertant release of the stub shaft 33 from the terminal portion 39. It is noteworthy-that the louvers may be rotated with whatever pressure is necessary from the front and, yet, the stub shaft will be retained within the terminal portion, since pressure from the front will not displace the stub shaft rearwardly out of the slot means because of the knee portion 37. The control panel is similarly retained in place against rearward movement by a pair of support webs 27 snapped into respective pairs of apertures 25 behind each end, as illustrated in dashed lines, FIG. 6. As illustrated therein, the control panel 15 has four protrusions, or tabs, 16 adjacent each comer that restrict its forward movement by engaging respectively the inner guid frame 21 and the inner edge 45 of the outer frame 19 and restrict its lateral movement by engaging the support webs 27 at each end. As indicated hereinbefore, the inner guide frame is conformingly fitted within the outer frame 19; the conforming fit being illustrated in FIG. 9 and described in connection therewith hereinafter; and the entire bezel structure assembly is then connected with the plenum of the fluid distribution system via fastener means and apertures 23. It is particularly noteworthy that no tools or other accessories are required in effecting assembly of this bezel structure or the louvers mounted therewithin.
As can be seen in FIG. 7, the outer frame 19 has a curved front that terminates in an inner edge 45. The inner guide frame 21 is adapted to fit within the outer frame 19 and to conforminly abut the inner edge 45 with a shoulder 47. To facilitate retaining abutment, the edge 45 and shoulder 47 may have conforming, stairstep construction 49. In any event, the inner surface 51 of the inner guide frame 21 defines a relatively streamlined flow boundary between the internal wall of the outer frame and the inner edge for eliminating turbulence. As can be seen in the prior art illustration of FIG. 8, the prior art bezels had a curved internal front portion 53 that induced eddy currents 55 that created turbulence and wasted energy, in addition to adversely afiecting the flow pattern of the discharged air.
FIG. 9 illustrates the assembled outer frame and inner guide frame, with the end cut away. to show more graphically the relatively streamlined flow boundary thereby effected. Specifically, the inner guide frame 21 is emplaced within the outer frame 19. The inner guide frame 21 has the respective support webs 27 snapped into place therein so as to receive four louvers. Ordinarily, the stub shafts of the respective louvers are snapped into the respective slot means 35 before the inner guide frame assembly is inserted. in this way the extra length of the terminal stub shafts may slide forwardly via a niche 57 in each end of the inner guide frame. Niche 57 extends forward to define a front portion 59 that can receive any excess length of stub shaft 33. This prevents the necessity of having to have two different length stub shafts, a shorter one for the terminal louvers and a longer one to interconnect between adjacent louvers on the remainder of the support webs 27.
The elements described hereinbefore are preferably formed of a material that will resist corrosion in the fluid being circulated. For example, it is preferred that the elements be formed of a plastic material so as to prevent corrosion due to the moisture of condensation from the cold air being circulated in an automotive air conditioning system. The plastics may either be thermosetting or thermoplastic plastics as long as they have the requisite rigidity and resistance to deformation under conditions of use. Well known thermosetting plastics like the phenol-formaldehyde copolymers may be employed. The thermosetting copolymers like the acrylonitrile-butadienestyrene copolymers also are satisfactory and may be employed. The thermoplastic plastics such as nylon may be employed for the stub shafts and the like.
This invention provides a bezel structure that satisfies the foregoing objects and obviates the disadvantages of the prior art structures in that it:
1 allows wide flexibility in effecting any final design;
2. provides a streamlined internal flow profile that eliminates eddy currents and minimizes turbulence; thereby improving flow patterns and fluid distribution;
3. employs readily assemblable snap-in structure that may be readily and manually snapped into place without requiring warehousing of additional parts and tools and costly and time consuming assembly of the parts; and
4. forms a snap-in structure that may be manipulated from the front without being inadvertently disassembled, because of its unique construction.
Once the advantageous features of employing multiple sets of stations within a given bezel structure are known, one skilled in the art may come up with other structures employing the principles of this invention without employing the exact structure delineated hereinbefore. The exact structure delineated hereinbefore is to be considered in an illustrative sense and not in a limiting sense. Numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
