Description:
FIELD OF THE INVENTION 
       [0001]    This invention relates to ceiling fans. 
         [0002]    More particularly, the present invention relates to hanger assemblies for depending a ceiling fan from an overhead support device. In a further and more specific aspect, the instant invention concerns an aesthetically enhanced hanger bracket of the above type. 
       BACKGROUND OF THE INVENTION 
       [0003]    Ceiling fans are conventionally suspended from a ceiling by means of a hanger assembly. A known hanger assembly includes a hanger bracket securable to an overhead support member such as an electrical junction box. The hanger bracket includes slots which receive screws there through for engagement with the flanges of the junction box. 
         [0004]    A ball socket is formed into the top of the hanger bracket. A ball, supported in the ball socket for swivel motion, supports a depending down rod. Attachment means, integral with the lower end of the down rod, are secured to the fan. A canopy, generally in the shape of an inverted dome, includes a central opening through which the down rod passes and an upper rim which encircles the peripheral sidewall of the hanger bracket. 
         [0005]    The rim of the canopy is secured to the hanger bracket by means of a plurality of screws which extend through openings in the rim of the canopy and threadedly engage within the hanger bracket. The heads of the screws reside external of the canopy. 
         [0006]    It is recognized that the exposed screw heads detract from the aesthetics of the hanger assembly. Accordingly, the prior art has provided a rim cover which encapsulates the screw heads. In accordance with one embodiment, the prior art has provided a rim cover having a plurality of J-shaped recesses formed into the inside surface which receive the heads of the screws. In accordance with another embodiment, the rim cover is fabricated of a resilient material. An annular groove formed in the inner surface of the resilient cover receives the screw heads in snap engagement. 
         [0007]    While encasing the screw heads, the rim covers provided by the prior art have not proven to be entirely satisfactory. Forming a J-shaped groove into the inner surface of the rim cover requires that the rim cover be extraordinarily thick. Also forming such grooves requires extraneous and relatively expensive manufacturing. Fabricating the rim cover of a resilient material detracts from the desired aesthetics. It is also noted that the screw heads tend to be relatively small with rounded exposed surfaces which do not adequately engage the prior art rim covers. 
         [0008]    It would be highly advantageous, therefore, to remedy the foregoing and other deficiencies inherent in the prior art. 
       SUMMARY OF THE INVENTION 
       [0009]    According to the principle of the invention, a hanger assembly for depending a fan from an overhead support includes a mounting bracket securable to the overhead support, a down rod to be suspended from the mounting bracket and having a lower end engagable with the fan, a canopy having a central opening for receiving the down rod there through and having an upper rim, mounting screws each extending through the rim of the canopy and engaged to the hanger bracket and having a head residing external of the rim of the canopy, and a rim cover for encapsulating the heads of the screws and securable with respect to the rim of the canopy. The rim cover has opposed fingers each having a lower end affixed to the rim cover and an opposing upper end, a notch between the opposed upper and lower ends, and opposed front and rear faces. There is a first gap between the opposed fingers extending from and between the upper ends of the fingers and the lower ends of the fingers, and a second gap between the rear faces of the fingers and the rim cover. The fingers are flexurally resilient in reciprocal directions relative to each other to admit the head of one of the screws into the first gap and into the notches formed in the fingers to embrace and secure the head of the screw. The fingers are also flexurally resilient in reciprocal directions relative to the rim cover. The rim cover includes an upper edge receivable in juxtaposition with the ceiling. The rim cover also includes an in turned lower edge receivable in juxtaposition with the canopy.

     DETAILED DESCRIPTION 
       [0066]    Turning now to the drawings, in which like reference characters indicate corresponding elements throughout the several views, attention is first directed to  FIG. 1  in which is seen a ceiling fan hanger assembly, incorporating the teachings of the instant invention and generally designated by reference character  20 . Hanger assembly  20  includes hanger bracket  21 , down rod  22 , canopy  23 , and rim cover  24 . 
         [0067]    Hanger bracket  21  includes base  30 , upper surface  31  and peripheral sidewall  32 . Spherical ball socket  35  is formed into bracket  21  at a generally central location. Slots  36  extending through base  30  accommodate mounting screws which pass through slots  36  and threadedly engage an overhead support member. Although the overhead support member is not specifically illustrated, those skilled in the art will readily appreciate that conventional overhead support members include electrical junction boxes, especially devised struts and beams, all of which are considered to be integral with a ceiling. Further, when hanger bracket  21  is secured to the overhead support member, upper surface  31  abuts the ceiling. 
         [0068]    Down rod  22  includes ball  40  which is to be matingly received within socket  35  in a conventional manner. Shaft  41 , having lower end  42 , depends from ball  40 . It will be readily understood by those skilled in the art that the lower terminal portion of shaft  41  adjacent lower end  42  can be threaded or otherwise configured for securement to a conventional ceiling fan. Bore  43  extending longitudinally through ball  40  and shaft  41  accommodate the electrical wires which extend from a junction box to the fan. 
         [0069]    Canopy  23  is generally in the shape of an inverted dome as illustrated in  FIG. 1  and  FIG. 2 . Referencing  FIG. 1 , canopy  23  includes a generally central opening  50  for receiving shaft  41  there through. Canopy  23  also includes an upper rim  51  sized and shaped to receive peripheral sidewall  32  of hanger bracket  21  therein. 
         [0070]    A plurality of openings extend through upper rim  51  of canopy  23 , which are spaced to align with threaded bores in hanger bracket  21 . A screw  55  extends through each of the openings through upper rim  51  and threadedly engaged with a respective threaded bore in peripheral sidewall  32  of hanger bracket  21 . As illustrated in  FIG. 1  and  FIG. 3 , a head  56  of each respective screw  55  resides externally of upper rim  51  of canopy  23 . 
         [0071]    Rim cover  24 , illustrated in further detail in  FIG. 2 ,  FIG. 3 , and  FIG. 4 , includes sidewall  60  having upper edge  61  and lower edge  62  (lower edge  62  not illustrated in  FIG. 3 ). Rim cover  34  is sized to extend about and encapsulate heads  56  of screws  55 . A plurality of clamps  70  are formed inwardly with respect to sidewall  60 . 
         [0072]    Clamps  70  are fabricated of a resilient material. Clamps  70  are identical to each other and each include, as shown in  FIG. 6  and  FIG. 7 , opposed and confronting upstanding fingers  71  and  71 ′ integrally formed with sidewall  60 . Fingers  71  and  71 ′ are the minor image of one another and are substantially coextensive. Fingers  71  have upper ends  72  and  72 ′ and opposed lower ends  73  and  73 ′, respectively, affixed to sidewall  60  of rim cover  24  just inboard of lower edge  62 . Fingers  71  and  71 ′ project upwardly from lower edge  62  and terminate with upper ends  72  and  72 ′, respectively, which upper ends  72  and  72 ′ are directed toward upper edge  61 . 
         [0073]    Fingers  71  and  71 ′ are spaced apart from each other, in which there is a gap  80  therebetween extending from and between upper ends  72  and  72 ′ of fingers  71  and  71 ′ to lower ends  73  and  73 ′ of fingers  71  and  71 ′. Notches  74  and  74 ′ are formed in fingers  71  and  71 ′, respectively. Notch  74  is formed between upper and lower ends  72  and  73  of finger  71 , and notch  74 ′ is formed between upper and lower ends  72 ′ and  73 ′ of finger  71 ′. Notches  74  and  74 ′ oppose and face inwardly toward one other and are substantially equal in size. Finger  71  has opposed front and rear faces  75  and  76 , and finger  71 ′ has opposed front and rear faces  75 ′ and  76 ′. Rear faces  76  and  76 ′ face sidewall  60 , in which there is a gap  81  therebetween rear face  76  and sidewall  60  and a gap  81 ′ therebetween rear face  76 ′ and sidewall  60 . 
         [0074]    Upper ends  72  and  72 ′ of fingers  71  and  71 ′ are formed with out turned portions  72 A and  72 A′, and are directed inwardly with respect to each other or are otherwise in turned with respect to each other, in which the width of gap  80  between upper ends  72  and  72 ′ of fingers  71  and  71 ′ is narrowed with respect to the width of gap  80  between notches  74  and  74 ′. Out turned portions  72 A and  72 A′ are out turned with respect to notches  74  and  74 ′, respectively. Fingers  71  and  71 ′ are flexurally resilient in reciprocal directions relative to sidewall  60  of rim cover  24  as indicated by the double arrowed line A in  FIG. 1 ,  FIG. 3 ,  FIG. 4 ,  FIG. 5 , and  FIG. 6 , and are flexurally resilient in reciprocal directions relative to each other as indicated by the double arrowed line B in  FIG. 1 ,  FIG. 3 ,  FIG. 4 ,  FIG. 6 , and  FIG. 7 . 
         [0075]    Referencing  FIG. 3 , heads  56  of screws  55  reside within the gaps  80  between fingers  71  and  71 ′ of the respective clamps  70 , and reside within and are held within the notches  74  and  74 ′ in fingers  71  and  71 ′ of the respective clamps  70  when hanger assembly  20  is assembled and secured to an overhead support member. Accordingly, rim cover  24  is received is clamp engagement with heads  56  of screws  55  to secure rim cover  24  with respect to canopy  23 . Clamps  70  are spaced apart with respect to each other, and are positioned to correspond to the positioning of the heads  56  of the respective screws  55  securing canopy  23  to hanger bracket  21 , and are aligned with the heads  56  of the respective screws  55  when fitting rim cover  24  about the upper rim  51  of canopy  23 . The integral formation of sidewall  60  with lower ends  73  and  73 ′ of fingers  71  and  71 ′ supporting notches  74  and  74 ′ is preferred, but it will be understood that lower ends  73  and  73 ′ of fingers  71  and  71 ′ can be welded to sidewall  60 , adhesively affixed to sidewall  60 , or rigidly affixed to sidewall  60  in other ways. 
         [0076]      FIG. 5  and  FIG. 7  illustrate head  56  of screw  55  as it would appear positioned in gap  80  between fingers  71  and  71 ′, positioned in notches  74  and  74 ′, and notches  74  and  74 ′ of fingers  71  and  71 ′ engaging and embracing head  56 . The flexural nature of fingers  71  and  71 ′ is thus provided in such a way that fingers  71  and  71 ′ bias toward head  56  biasing notches  74  and  74 ′ toward and against head  56  of screw  55  when installed therewith for providing a clamping engagement or embracement of head  56  by and between fingers  71  and  71 ′, according to the principle of the invention. When rim cover  24  is clamp engaged with respect to upper rim  51  of canopy  23  such that clamps  70  are clamp engaged to the heads  56  of the respective screws  55 , fingers  71  and  71 ′ of the respective clamps  70  are received in juxtaposition with respect to upper rim  51  of canopy  23  as shown in  FIG. 3 . This aspect is also illustrated in  FIG. 5 , which shows clamp  100  clamp engaged to head  56  of screw  55 , and finger  71  of clamp  70  received in juxtaposition with respect to upper rim  51  of canopy  23 . 
         [0077]    Fingers  71  and  71 ′ of each clamp  70  are flexurally resilient in reciprocal directions relative to each other to admit head  56  of screw  55  into gap  80  and into notches  74  and  74 ′ formed in fingers  71  and  71 ′ to embrace and secure head  56  of screw  55 . The flexural character of fingers  71  and  71 ′ allow them to flex outwardly and away from each other as needed for installing rim cover  24  to canopy  23  and removing rim cover  24  from canopy  24 . Rim cover  24  is brought upwardly toward upper rim  51  of canopy  23  and is maneuvered to register clamps  70  with the respective heads  56  of screws  55 . With respect to each clamp  70 , head  56  of screw  55  is initially received against out turned portions  72 A and  72 A′ of fingers  71  and  71 ′. Through the application of an upward force, head  56  acts on out turned portions  72 A and  72 A′ of fingers  71  and  71 ′ spreading fingers  71  apart widening gap  80  between upper ends  72  and  72 ′ permitting head  56  to pass into gap  80  the notches  74  and  74 ′, in which fingers  71  and  71 ′ then flex inwardly with respect to each other toward the head  56  engaging notches  74  and  74 ′ of fingers  71  against head  56  clamping and embracing head  56  thereby clamping and securing head  56  and clamp securing rim cover  24  with respect to upper rim  51  of canopy  23 . 
         [0078]    As further seen in  FIG. 2 , when hanger assembly  20  is assembled and installed, upper edge  61  of rim cover  24  resides in juxtaposition with ceiling  90 . Lower edge  62  of rim cover  24  is in turned to reside in juxtaposition with canopy  24  as illustrated in  FIG. 2  and  FIG. 5 . 
         [0079]    Hanger assembly  20  includes four screws  55  and four corresponding clamps  70  in the present embodiment. Those of ordinary skill will readily appreciate that hanger assembly  20  may incorporate any number of screws  55  to secure canopy  23  to hanger bracket  21 , and that rim cover  24  may be constructed with the appropriate number of clamps  70  to correspond with whatever number of screws  55  hanger assembly  20  utilizes. 
         [0080]    In hanger assembly  20 , clamps  70  formed in rim cover  24  each relate to the head  56  of one of the respective screws  56  securing canopy  23  to hanger bracket  21 . In the ensuing two alternate embodiments, the first of which is presented in  FIGS. 8-13  and the second of which is presented in  FIGS. 14-19 , the clamps formed in the rim covers each relate to two screw heads. 
         [0081]    Reference is now made to  FIGS. 8 and 9 , in which is seen an alternate embodiment of a ceiling fan hanger assembly, incorporating the teachings of the instant invention and generally designated by reference character  100 . In common with hanger assembly  20 , hanger assembly  100  shares hanger bracket  21 , down rod  22 , canopy  23 , and screws  55  formed with heads  56 , and also includes an alternate embodiment of a rim cover denoted at  101 . The details with respect to bracket  21 , down rod  22 , and canopy  23  and the assembly thereof are as in the embodiment of hanger assembly designated  20 , the details of which apply equally with respect to hanger assembly  100  and will not again be discussed. 
         [0082]    Rim cover  101 , illustrated in detail in  FIG. 8 ,  FIG. 9 , and  FIG. 10 , is common to rim cover  24  in that rim cover  100  shares upper edge  61  and lower edge  62  (lower edge  62  not illustrated in  FIG. 9 ) and which is sized to extend about and encapsulate heads  56  of screws  55  as in hanger assembly  20 . A plurality of clamps, denoted generally at  110 , are formed inwardly with respect to sidewall  60  that, unlike clamps  70  in hanger bracket  20 , are each configured to clamp the heads  56  of two screws  55 . 
         [0083]    Clamps  110  are fabricated of a resilient material and are identical to each other. Referencing  FIG. 13 , clamps  110  each include opposed and confronting upstanding fingers  111  and  111 ′ integrally formed with sidewall  60 . Fingers  111  and  111 ′ are the minor image of one another and are substantially coextensive. Fingers  101  have upper ends  112  and  112 ′ and opposed lower ends  113  and  113 ′, respectively, affixed to sidewall  60  of rim cover  101  just inboard of lower edge  62 . Fingers  111  and  111 ′ project upwardly from lower edge  62  and terminate with upper ends  112  and  112 ′, respectively, which upper ends  112  and  112 ′ are directed toward upper edge  61 . 
         [0084]    Rim cover  100  is generally circular in shape, and fingers  111  and  111 ′ are circumferentially spaced apart from each other and are further positioned to relate to the heads  56  of a pair of respective screws  55  securing canopy  23  to hanger bracket  21 . Notches  114  and  114 ′ are formed in fingers  111  and  111 ′, respectively. Notch  114  is formed between upper and lower ends  112  and  113  of finger  111 , and notch  114 ′ is formed between upper and lower ends  112 ′ and  113 ′ of finger  111 ′. Notches  114  and  114 ′ oppose and substantially face inwardly toward one another and are substantially equal in size. Finger  111  has opposed front and rear faces  115  and  116  denoted in  FIG. 9 ,  FIG. 11 , and  FIG. 12 , and finger  111 ′ has opposed front and rear faces  115 ′ and  116 ′ denoted in  FIG. 9 . Rear faces  116  and  116 ′ face sidewall  60 , in which there is a gap  120  therebetween rear face  116  and sidewall  60  illustrated in  FIG. 9 ,  FIG. 10 ,  FIG. 11 , and  FIG. 12 , and a gap  120 ′ therebetween rear face  116 ′ and sidewall  60  illustrated in  FIG. 9  and  FIG. 10 . 
         [0085]    Upper ends  112  and  112 ′ of fingers  111  and  111 ′ are formed with out turned portions  112 A and  112 A′. Out turned portions  112 A and  112 A′ are out turned with respect to notches  114  and  114 ′, respectively. Fingers  111  and  111 ′ are flexurally resilient in reciprocal directions relative to sidewall  60  of rim cover  101 , each as indicated by a double arrowed line C in  FIG. 8 ,  FIG. 9 ,  FIG. 10 ,  FIG. 11 , and  FIG. 12 , and are flexurally resilient in reciprocal directions substantially relative to each other, each as indicated by a double arrowed line D in  FIG. 8 ,  FIG. 9 ,  FIG. 10 ,  FIG. 12 , and  FIG. 13 . 
         [0086]    Referencing  FIG. 13 , heads  56  of screws  55  reside between fingers  111  and  111 ′ of clamp  110 , and reside within and are held within the notches  114  and  114 ′ in fingers  111  and  111 ′ of clamp  110  when hanger assembly  20  is assembled and secured to an overhead support member, in which notches  114  and  114 ′ are applied against outer sides  56 A of the heads  56  of the respective screws  55 . Accordingly, rim cover  101  is received is clamp engagement with heads  56  of screws  55  to secure rim cover  101  with respect to canopy  23 . Fingers  111  and  111 ′ are spaced apart with respect to each other, and are positioned to correspond to the positioning of the heads  56  of the respective two screws  55  securing canopy  23  to hanger bracket  21 , and are aligned with the heads  56  of the respective two screws  55  when fitting rim cover  101  about the upper rim  51  of canopy  23 . The integral formation of sidewall  60  with lower ends  113  and  113 ′ of fingers  111  and  111 ′ supporting notches  114  and  114 ′ is preferred, but it will be understood that lower ends  113  and  113 ′ of fingers  111  and  111 ′ can be welded to sidewall  60 , adhesively affixed to sidewall  60 , or rigidly affixed to sidewall  60  in other ways. 
         [0087]      FIG. 13  illustrate the heads  56  of the two screws  55  positioned between fingers  111  and  111 ′, and the outer sides  56 A of the heads  56  of the respective two screws positioned in or otherwise received by notches  114  and  114 ′ formed in the respective fingers  111  and  111 ′ engaging and embracing heads  56 .  FIG. 12  is an enlarged view illustrating head  56  of screw  55  located in notch  114  formed in finger  111 . The flexural nature of fingers  111  and  111 ′ is thus provided in such a way that fingers  111  and  111 ′ bias toward the outer sides  56 A of the respective heads  56  biasing notches  114  and  114 ′ toward and against the outer sides  56 A of the respective heads  56  when installed therewith for providing a clamping engagement or embracement of heads  56  by and between fingers  111  and  111 ′, according to the principle of the invention. When rim cover  24  is clamp engaged with respect to upper rim  51  of canopy  23  such that clamps  110  are clamp engaged to the heads  56  of two screws  55 , fingers  111  and  111 ′ of the clamp  110  are received in juxtaposition with respect to upper rim  51  of canopy  23  as illustrated in  FIG. 9 . This aspect is also illustrated in  FIG. 5 , which shows finger  111  of clamp  110  clamp engaged to head  56  of screw  55 , and finger  111  of clamp  110  received in juxtaposition with respect to upper rim  51  of canopy  23 . 
         [0088]    Fingers  111  and  111 ′ of each clamp  110  are flexurally resilient in reciprocal directions to concurrently admit heads  56  of screws  55  between fingers  111  and  111 ′ and into notches  114  and  114 ′ formed in fingers  111  and  111 ′, respectively, to embrace and secure heads  56  of screws  55 . The flexural character of fingers  111  and  111 ′ allow them to flex outwardly and away from each other as needed for installing rim cover  101  to canopy  23  and removing rim cover  101  from canopy  101 . Rim cover  101  is brought upwardly toward upper rim  51  of canopy  23  and is maneuvered to register fingers  111  and  111 ′ with the respective heads  56  of screws  55 . The heads  56  of the respective screws  55  are initially received against out turned portions  112 A and  112 A′ of the respective fingers  111  and  111 ′. Through the application of an upward force, heads  56  of the respective screws  55  act on out turned portions  112 A and  112 A′ of fingers  111  and  111 ′, respectively, spreading fingers  111  and  111 ′ apart from each other permitting the heads  56  of the respective screws  55  to pass between fingers  111  and  111 ′ to notches  114  and  114 ′, in which fingers  111  and  111 ′ then flex inwardly with respect to each other toward the outer sides  56 A of the heads  56  of the respective screws  55  engaging notches  114  and  114 ′ of fingers  101  against the outer sides  56 A of the heads  56  of the respective screws  55  clamping and embracing heads  56  between fingers  111  and  111 ′ thereby clamping and securing heads  56  and clamp securing rim cover  101  with respect to upper rim  51  of canopy  23 .

Rim cover  141  is brought upwardly toward upper rim  51  of canopy  23  and is maneuvered to register fingers  151  and  151 ′ with the respective heads  56  of screws  55 . The heads  56  of the respective screws  55  are initially received against out turned portions  152 A and  152 A′ of the respective fingers  151  and  151 ′ . Through the application of an upward force, heads  56  of the respective screws  55  act on out turned portions  152 A and  152 A′ of fingers  151  and  151 ′, respectively, spreading fingers  151  and  151 ′ inwardly toward each other permitting the heads  56  of the respective screws  55  to pass between fingers  151  and  151 ′ to notches  154  and  154 ′, in which fingers  151  and  151 ′ then flex outwardly with respect to each other toward the inner sides  56 B of the heads  56  of the respective screws  55  engaging notches  154  and  154 ′ of fingers  141  against the inner sides  56 B of the heads  56  of the respective screws  55  clamping and embracing heads  56  on either side of fingers  151  and  151 ′ thereby clamping and securing heads  56  and clamp securing rim cover  141  with respect to upper rim  51  of canopy  23 . 
         [0099]    Like hanger assembly  20  illustrated in  FIG. 2 , when hanger assembly  140  is assembled and installed, upper edge  61  of rim cover  141  resides in juxtaposition with the ceiling. Further, lower edge  62  of rim cover  141  is in turned to reside in juxtaposition with canopy  141  as illustrated in  FIG. 17 . 
         [0100]    Those of ordinary skill will readily appreciate that hanger assembly  140  may incorporate any number of screws  55  to secure canopy  23  to hanger bracket  21 , and that rim cover  141  may be constructed with the appropriate number of clamps  150  to correspond the number of screws  55  hanger assembly  100  utilizes, with the understanding that each clamp  150  relates to two heads of two screws. 
         [0101]    Reference is now directed to  FIG. 20 , in which there is seen a ceiling fan hanger assembly, incorporating the teachings of the instant invention and generally designated by reference character  200 . Hanger assembly  200  includes hanger bracket  201 , down rod  202 , canopy  203 , and rim cover  204 . 
         [0102]    Hanger bracket  201  includes base  210 , upper surface  211  and peripheral sidewall  212 . Spherical ball socket  214  is formed into bracket  201  at a generally central location. Slots  215  extending through base  210  accommodate mounting screws which pass through slots  215  and threadedly engage an overhead support member. Although the overhead support member is not specifically illustrated in connection with hanger assembly  200 , those skilled in the art will readily appreciate that conventional overhead support members include electrical junction boxes, especially devised struts and beams, all of which are considered to be integral with a ceiling. Further, when hanger bracket  201  is secured to the overhead support member, upper surface  211  abuts the ceiling. 
         [0103]    Down rod  202  includes ball  220  which is to be matingly received within socket  214  in a conventional manner. Shaft  221 , having lower end  222 , depends from ball  220 . It will be readily understood by those skilled in the art that the lower terminal portion of shaft  221  adjacent to lower end  222  can be threaded or otherwise configured for securement to a conventional ceiling fan. Bore  223  extending longitudinally through ball  220  and shaft  221  accommodate the electrical wires which extend from a junction box to the fan. Canopy  203  is generally in the shape of an inverted dome as illustrated in  FIG. 20  and  FIG. 21 . Referencing  FIG. 20 , canopy  203  includes a generally central opening  230  for receiving shaft  221  there through. Canopy  203  also includes an upper rim  231 , having an upper marginal edge  232 , sized and shaped to receive peripheral sidewall  212  of hanger bracket  201  therein. 
         [0104]    A plurality of openings extend through upper rim  231  of canopy  203 , which are spaced to align with threaded bores in hanger bracket  221 . A screw  235  extends through each of the openings through upper rim  231  and threadedly engages a respective threaded bore in peripheral sidewall  212  of hanger bracket  221 . As illustrated in  FIG. 20  and  FIG. 22 , a head  236  of each respective screw  235  resides externally of upper rim  231  of canopy  203 . A plurality of circumferentially spaced apart protrusions  238  are formed into upper rim  231  of canopy  203 . 
         [0105]    Rim cover  204 , illustrated in further detail in  FIG. 21  and  FIG. 22 , is generally circular in shape and includes sidewall  240  having upper edge  241  and lower edge  242  and which is sized to extend about and encapsulate heads  236  of screws  235 . A plurality of circumferentially spaced apart indentations  244  projects inwardly with respect to sidewall  240 , and are positioned to relate to the respective protrusions  238 . Preferably, the indentations  244  each have a base  245  which is integrally formed with sidewall  240 . The integral formation of sidewall  240  with bases  245  supporting indentations  244  is preferred, but it will be understood that bases  245  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. Furthermore, indentations  244  are each preferably integrally formed with its respective base  245 . 
         [0106]    A plurality of circumferentially spaced apart spacers  247  project inwardly from sidewall  240  and each terminate with an inwardly directed edge  248 . Spacers  247  are substantially equal in size and shape, and are spaced apart with respect to indentations  244 . Preferably, spacers  247  are integrally formed with sidewall  240 . The integral formation of sidewall  240  with spacers  247  is preferred, but it will be understood that spacers  247  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. Furthermore, indentations  244  are each preferably integrally formed with its respective base  245 . 
         [0107]    Looking to  FIG. 24 , each indentation  244  relates to and matingly receives therein or otherwise accepts a respective protrusion  238  when hanger assembly  200  is assembled and secured to an overhead support member. Each protrusion  245  and corresponding indentation  244  pair form an engagement pair, in which one is an element of the engagement pair and the other is the corresponding or complemental element of the engagement pair. Accordingly, rim cover  204  is received in snap engagement with canopy  203 . As further seen in  FIG. 23 , when the hanger assembly  200  is assembled and installed, the upper edge  241  of rim cover  204  resides in juxtaposition with ceiling  250 , and lower edge  242  of rim cover  204  is in turned to reside in juxtaposition with canopy  203 , which is also shown in  FIG. 24 . Spacers  247  carried by rim cover  204  are positioned between rim cover  204  of upper rim  231  of canopy  203  and edges  248  of spacers  247  are received in juxtaposition with respect to upper rim  231  of canopy  203 , whereby spacers  247  interact between upper rim  231  of canopy  203  and rim cover  204  to set rim cover  204  at a substantially fixed circumferential spacing relative to upper rim  231  of canopy  203  as shown in  FIG. 22 . 
         [0108]    Referencing  FIG. 25  and  FIG. 27 , each base  245  consists of an upstanding finger  260 . Finger  260  has an upper end  261  and an opposing lower end  262  affixed to sidewall  240  of rim cover  204  at lower edge  242 . Finger  260  projects upwardly from lower edge  242  and terminates with upper end  261 , which is directed toward upper edge  241 . Finger  260  has a front face  270  into which indentation  244  is formed, and an opposing rear face  271  facing sidewall  240 , and there is a gap  272  therebetween. A beveled surface  274  is formed in front face  270  of finger  260  proximate to upper end  261  of finger  260 . Indentation  244  is formed in front face  270  of finger  260 , and is located between beveled surface  274  and lower end  262 . Finger  260  is flexible, and flexes in reciprocal directions relative to sidewall  240  as indicated by the double arrowed line G in  FIG. 24 . The flexural character of finger  260  allows it to flex as needed for installing rim cover  204  to canopy  203  and removing rim cover  204  from canopy  203 .  FIG. 24  illustrates protrusion  238  as it would appear received by and engaging indentation  244  formed in front face  270  of finger  260 . The flexural nature of finger  260  is also provided in such a way that finger  260  biases indentation  244  toward and against protrusion  238  when installed therewith for providing a rugged and forcible engagement of protrusion  238  in and against indentation  244 . Preferably, lower end  262  of finger  260  is integrally formed with sidewall  240 . The integral formation of lower end  262  of finger  260  with sidewall  240  is preferred, but it will be understood that lower end  262  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. 
         [0109]    To install rim cover  204 , rim cover  204  is brought upwardly toward upper rim  231  of canopy  203  and is maneuvered to register fingers  260  with the respective protrusions  238 . With respect to each finger  260 , beveled surface  274  is initially received against a corresponding protrusion  238  of canopy  203 . Through the application of an upward force, protrusion  238  acts on beveled surface  274  deflecting finger  260  outwardly toward sidewall  240  permitting protrusion  238  to encounter indentation  244  and finger  260  then deflects away from sidewall  240  toward protrusion  238  snap receiving protrusion  238  within indentation  244  securing rim cover  204  with respect to upper rim  231  of canopy  203 . 
         [0110]    Indentation  244  is bound on either side by opposed, substantially parallel sidewalls  280  and  281  shown in  FIG. 25  and in  FIG. 26 , and is bound on either end by opposed, substantially parallel top and bottom walls  284  and  285  shown in  FIG. 24  and in  FIG. 25 , which extend between sidewalls  280  and  281 . Indentation  244  is sized to receive a protrusion  238 , opposed sidewalls  280  and  281  interact with the protrusion  238  on either side of protrusion  238  as shown in  FIG. 26  to constrain or otherwise prevent rim cover  204  from horizontally displacing with respect to canopy  203 , and top and bottom walls  284  and  285  interact with the protrusion  238  along the top and bottom of protrusion  238  as shown in  FIG. 24  to constrain or otherwise prevent rim cover  204  from vertically displacing with respect to canopy  203 . 
         [0111]    In the preferred embodiment of hanger assembly  200 , indentation  244  of each engagement pair is carried by finger  260  and the corresponding protrusion  238  is carried by canopy  203 . If desired, this arrangement can be reversed. 
         [0112]    Reference is now directed to  FIG. 28 , in which there is seen a ceiling fan hanger assembly, incorporating the teachings of the instant invention and generally designated by reference character  300 .

         [0115]    A plurality of openings extend through upper rim  311  of canopy  301 , which are spaced to align with threaded bores in hanger bracket  221 . Screw  235  extends through each of the openings through upper rim  311  and threadedly engages a respective threaded bore in peripheral sidewall  212  of hanger bracket  221 . As illustrated in  FIG. 28  and  FIG. 30 , head  236  of each respective screw  235  resides externally of upper rim  311  of canopy  301 . According to the principle of the invention, a circumferential continuous groove  314  is formed into upper rim  311  of canopy  301 , as illustrated in  FIG. 28  and  FIG. 32 . Heads  236  of screws  235  each reside external of the upper rim  311  of canopy  301  within continuous groove  314 , and rim cover  302  is for encapsulating heads  236  of screws  235  located in continuous groove  314  and is securable with respect to upper rim  311  of canopy  301 . A continuous, parametric rim or abutment  315  is formed in canopy  301  proximate to upper rim  311 , projects outward with respect to canopy  301 , and is positioned underneath groove  314 . 
         [0116]    Rim cover  302 , illustrated in further detail in  FIG. 29  and  FIG. 30 , is generally circular in shape and includes sidewall  240  having upper edge  241  and lower edge  242  and which is sized to extend about and encapsulate heads  236  of screws  235  residing in continuous groove  314 . A plurality of circumferentially spaced apart protrusions  316  projects inwardly from sidewall  240 , and are positioned to relate to continuous groove  314 . Preferably, the protrusions  316  each have base  245  which is integrally formed with sidewall  240 . The integral formation of sidewall  240  with bases  245  supporting protrusions  316  is preferred, but it will be understood that bases  245  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. Furthermore, protrusions  316  are each preferably integrally formed with its respective base  245 . 
         [0117]    Spacers  247  project inwardly from sidewall  240  and each terminate with inwardly directed edge  248 . Spacers  247  are substantially equal in size and shape, and are preferably integrally formed with sidewall  240 . The integral formation of sidewall  240  with spacers  247  is preferred, but it will be understood that spacers  247  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. Furthermore, protrusions  316  are each preferably integrally formed with its respective base  245 . 
         [0118]    Referencing  FIG. 33 , each protrusion  316  is received by and into continuous groove  314  when hanger assembly  300  is assembled and secured to an overhead support member securing and suspending rim cover  302  with respect to canopy  301 . Groove  314  and each protrusion  316  form an engagement pair, in which one is an element of the engagement pair and the other is the corresponding or complemental element of the engagement pair. 
         [0119]    The continuous groove  314  and each protrusion  316  are an engagement pair. Accordingly, rim cover  302  is received in snap engagement with canopy  301 . As further seen in  FIG. 31 , when the hanger assembly  300  is assembled and installed, the upper edge  241  of rim cover  302  resides in juxtaposition with ceiling  250 , and lower edge  242  of rim cover  302  is in turned to reside in juxtaposition with canopy  301 , which is also shown in  FIG. 33 . Spacers  247  carried by rim cover  302  are positioned between rim cover  302  of upper rim  311  of canopy  301  and edges  248  of spacers  247  are received in juxtaposition with respect to upper rim  311  of canopy  301 , whereby spacers  247  interact between upper rim  311  of canopy  301  and rim cover  302  to set rim cover  302  at a substantially fixed circumferential spacing relative to upper rim  311  of canopy  301  as shown in  FIG. 30 . 
         [0120]    Referencing  FIG. 34 , each base  245  consists of upstanding finger  260 . Finger  260  has upper end  261  and opposing lower end  262  affixed to sidewall  240  of rim cover  302  at lower edge  242 . Finger  260  projects upwardly from lower edge  242  and terminates with upper end  261 , which is directed toward upper edge  241 . Finger  260  has front face  270  formed with protrusion  316 , and opposing rear face  271  facing sidewall  240 , and there is a gap  272  therebetween. Beveled surface  274  is formed in front face  270  of finger  260  proximate to upper end  261  of finger  260 . Protrusion  316  is formed in front face  270  of finger  260 , and is located between beveled surface  274  and lower end  262 . Finger  260  is flexible, and flexes in reciprocal directions relative to sidewall  240  as indicated by the double arrowed line H in  FIG. 33 . The flexural character of finger  260  allows it to flex as needed for installing rim cover  302  to canopy  301  and removing rim cover  302  from canopy  301 .  FIG. 33  illustrates protrusion  316  as it would appear received by and engaging groove  314  formed in upper rim  311  of canopy  30 . The flexural nature of finger  260  is also provided in such a way that finger  260  biases protrusion  316  toward and against continuous groove  314  when installed therewith for providing a rugged and forcible engagement of protrusion  316  in and against groove  314 . Preferably, lower end  262  of finger  260  is integrally formed with sidewall  240 . The integral formation of lower end  262  of finger  260  with sidewall  240  is preferred, but it will be understood that lower end  262  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. 
         [0121]    To install rim cover  302  in the present embodiment, rim cover  302  is brought upwardly toward upper rim  311  of canopy  301  and is maneuvered to register fingers  260  with groove  314 . With respect to each finger  260 , beveled surface  274  is initially received against abutment  315  of canopy  301 . Through the application of an upward force, abutment  315  acts on beveled surface  274  deflecting finger  260  away from canopy  301  toward sidewall  240  permitting protrusion  316  to encounter groove  314  and finger  260  then deflects away from sidewall  240  toward groove  314  snap receiving protrusion  316  within groove  314  engaging protrusion  316  with groove  314  suspending and securing rim cover  302  with respect to upper rim  311  of canopy  301 . 
         [0122]    Reference is now directed to  FIG. 35 , in which there is seen a ceiling fan hanger assembly, incorporating the teachings of the instant invention and generally designated by reference character  320 . In common with hanger assembly  300 , hanger assembly  320  shares hanger bracket  201 , down rod  202 , and rim cover  302 , and incorporates an alternate embodiment of a canopy denoted at  321 .

Down rod  202  includes ball  220  which is to be matingly received within socket  214 . Shaft  221 , having lower end  222 , depends from ball  220 , and the lower terminal portion of shaft  221  adjacent to lower end  222  can be threaded or otherwise configured for securement to a conventional ceiling fan. Bore  223  extends longitudinally through ball  220  and shaft  221  and accommodates the electrical wires which extend from a junction box to the fan. 
         [0124]    Canopy  321  is generally in the shape of an inverted dome as illustrated in  FIG. 35  and  FIG. 36 . Referencing  FIG. 35 , canopy  321  includes a generally central opening  330  for receiving shaft  221  there through. Canopy  321  also includes an upper rim  331 , having an upper marginal edge  332 , sized and shaped to receive peripheral sidewall  212  of hanger bracket  201  therein. 
         [0125]    A plurality of openings extend through upper rim  331  of canopy  321 , which are spaced to align with threaded bores in hanger bracket  221 . Screw  235  extends through each of the openings through upper rim  331  and threadedly engages a respective threaded bore in peripheral sidewall  212  of hanger bracket  221 . As illustrated in  FIG. 35  and  FIG. 37 , head  236  of each respective screw  235  resides externally of upper rim  331  of canopy  321 . A plurality of circumferentially spaced apart slots  334  is formed into upper rim  331  of canopy  321 . Slots  334  in canopy  331 , which are also shown in  FIG. 39 , extend through upper rim  331  of canopy  321 , and are each circumferentially elongate. A continuous, parametric rim or abutment  335  is formed in canopy  321  proximate to upper rim  331 , projects outward with respect to canopy  321 , and is positioned underneath slots  334 . 
         [0126]    Rim cover  302 , illustrated in further detail in  FIG. 36  and  FIG. 37 , is generally circular in shape and includes sidewall  240  having upper edge  241  and lower edge  242  and which is sized to extend about and encapsulate heads  236  of screws  235 . The plurality of circumferentially spaced apart protrusions  316  project inwardly from sidewall  240 , and are each positioned to relate to a slot  334 . Preferably, the protrusions  316  each have base  245  which is integrally formed with sidewall  240 . The integral formation of sidewall  240  with bases  245  supporting protrusions  316  is preferred, but it will be understood that bases  245  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. Furthermore, protrusions  316  are each preferably integrally formed with its respective base  245 . 
         [0127]    Spacers  247  project inwardly from sidewall  240  and each terminate with inwardly directed edge  248 . Spacers  247  are substantially equal in size and shape, and are preferably integrally formed with sidewall  240 . The integral formation of sidewall  240  with spacers  247  is preferred, but it will be understood that spacers  247  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. Furthermore, protrusions  316  are each preferably integrally formed with its respective base  245 . 
         [0128]    Looking to  FIG. 40 , each protrusion  316  is received by and within a corresponding slot  334  when hanger assembly  320  is assembled and secured to an overhead support member. Each protrusion  316  and corresponding slot  334  pair form an engagement pair, in which one is an element of the engagement pair and the other is the corresponding or complemental element of the engagement pair. Accordingly, rim cover  302  is received in snap engagement with canopy  321 . Preferably, each slot  334  is circumferentially elongate thereby eliminating the necessity of precise alignment when fitting rim cover  302  about upper rim  331  of canopy  321 . 
         [0129]    As further seen in  FIG. 38 , when the hanger assembly  320  is assembled and installed, the upper edge  241  of rim cover  302  resides in juxtaposition with ceiling  250 , and lower edge  242  of rim cover  302  is in turned to reside in juxtaposition with canopy  321 , which is also shown in  FIG. 40 . Spacers  247  carried by rim cover  302  are positioned between rim cover  302  of upper rim  331  of canopy  321  and edges  248  of spacers  247  are received in juxtaposition with respect to upper rim  331  of canopy  321 , whereby spacers  247  interact between upper rim  331  of canopy  321  and rim cover  302  to set rim cover  302  at a substantially fixed circumferential spacing relative to upper rim  331  of canopy  321  as shown in  FIG. 37 . 
         [0130]    Referencing  FIG. 41 , each base  245  consists of upstanding finger  260 . Finger  260  has upper end  261  and opposing lower end  262  affixed to sidewall  240  of rim cover  302  at lower edge  242 . Finger  260  projects upwardly from lower edge  242  and terminates with upper end  261 , which is directed toward upper edge  241 . Finger  260  has front face  270  formed with protrusion  316 , and an opposing rear face  271  facing sidewall  240 , and there is a gap  272  therebetween. Beveled surface  274  is formed in front face  270  of finger  260  proximate to upper end  261  of finger  260 . Protrusion  316  is formed in front face  270  of finger  260 , and is located between beveled surface  274  and lower end  262 . Finger  260  is flexible, and flexes in reciprocal directions relative to sidewall  240  as indicated by the double arrowed line I in  FIG. 40 . The flexural character of finger  260  allows it to flex as needed for installing rim cover  302  to canopy  321  and removing rim cover  302  from canopy  321 .  FIG. 40  illustrates protrusion  316  as it would appear received by, extending through, and engaging slot  334  formed in upper rim  331  of canopy  30 . The flexural nature of finger  260  is also provided in such a way that finger  260  biases protrusion  316  toward and into and through slot  334  when installed therewith for providing a rugged and forcible engagement of protrusion  316  in, to, and through slot  334 . Preferably, lower end  262  of finger  260  is integrally formed with sidewall  240 . The integral formation of lower end  262  of finger  260  with sidewall  240  is preferred, but it will be understood that lower end  262  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. 
         [0131]    To install rim cover  302  in the present embodiment, rim cover  302  is brought upwardly toward upper rim  331  of canopy  321  and is maneuvered to register fingers  260  with slots  334 . With respect to each finger  260 , beveled surface  274  is initially received against abutment  335  of canopy  321 . Through the application of an upward force, abutment  335  acts on beveled surface  274  deflecting finger  260  outwardly away from canopy  321  toward sidewall  240  permitting protrusion  316  to encounter a corresponding slot  334 , at which point finger  260  then deflects away from sidewall  240  toward slot  334  in canopy  321  snap receiving protrusion  316  within and into and through slot  334  suspending and securing rim cover  302  with respect to upper rim  331  of canopy  321 . 
         [0132]    In the preferred embodiment of hanger assembly  320 , protrusion  316  of each engagement pair is carried by finger  260  and the corresponding slot  334  is carried by canopy  321 . If desired, this arrangement can be reversed. 
         [0133]    Reference is now directed to  FIG. 42 , in which there is seen a ceiling fan hanger assembly, incorporating the teachings of the instant invention and generally designated by reference character  340 . In common with hanger assembly  300 , hanger assembly  340  shares hanger bracket  201 , down rod  202 , and rim cover  302 , and incorporates an alternate embodiment of a canopy denoted at  341 . 
         [0134]    Hanger bracket  201  includes base  210 , upper surface  211  and peripheral sidewall  212 , spherical ball socket  214 , and slots  215  extending through base  210  accommodate mounting screws which pass through slots  215  and threadedly engage an overhead support member. Down rod  202  includes ball  220  which is to be matingly received within socket  214 . Shaft  221 , having lower end  222 , depends from ball  220 , and the lower terminal portion of shaft  221  adjacent to lower end  222  can be threaded or otherwise configured for securement to a conventional ceiling fan. Bore  223  extends longitudinally through ball  220  and shaft  221  and accommodates the electrical wires which extend from a junction box to the fan. 
         [0135]    Canopy  341  is generally in the shape of an inverted dome as illustrated in  FIG. 35  and  FIG. 36 . Referencing  FIG. 35 , canopy  341  includes a generally central opening  350  for receiving shaft  221  there through. Canopy  341  also includes an upper rim  351 , having an upper marginal edge  352 , sized and shaped to receive peripheral sidewall  212  of hanger bracket  201  therein. 
         [0136]    A plurality of openings extend through upper rim  351  of canopy  341 , which are spaced to align with threaded bores in hanger bracket  221 . Screw  235  extends through each of the openings through upper rim  351  and threadedly engages a respective threaded bore in peripheral sidewall  212  of hanger bracket  221 . As illustrated in  FIG. 42  and  FIG. 44 , head  236  of each respective screw  235  resides externally of upper rim  351  of canopy  341 . A plurality of circumferentially spaced apart notches  334  is formed into upper rim  351  of canopy  341 . Notches  354  in canopy  351 , which are also shown in  FIG. 46 , extend through upper rim  351  of canopy  341 , and are each circumferentially elongate. A continuous, parametric rim or abutment  335  is formed in canopy  341  proximate to upper rim  351 , projects outward with respect to canopy  341 , and is positioned underneath notches  354 . Each notch  354  extends downwardly into upper rim  351  of canopy  341  from upper marginal edge  352  and terminates with a horizontal lower edge  360  extending between opposed vertical side edges  361  and  362  formed in canopy  341  and which cooperate to form and bound notch  354 . ; 
         [0137]    Rim cover  302 , illustrated in further detail in  FIG. 43  and  FIG. 44 , is generally circular in shape and includes sidewall  240  having upper edge  241  and lower edge  242  and which is sized to extend about and encapsulate heads  236  of screws  235 . The plurality of circumferentially spaced apart protrusions  316  projects inwardly from sidewall  240 , and are each positioned to relate to a notch  354 . Preferably, the protrusions  316  each have base  245  which is integrally formed with sidewall  240 . The integral formation of sidewall  240  with bases  245  supporting protrusions  316  is preferred, but it will be understood that bases  245  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. Furthermore, protrusions  316  are each preferably integrally formed with its respective base  245 . 
         [0138]    Spacers  247  project inwardly from sidewall  240  and each terminate with inwardly directed edge  248 . Spacers  247  are substantially equal in size and shape, and are preferably integrally formed with sidewall  240 . The integral formation of sidewall  240  with spacers  247  is preferred, but it will be understood that spacers  247  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. Furthermore, protrusions  316  are each preferably integrally formed with its respective base  245 . 
         [0139]    Looking to  FIG. 47 , each protrusion  316  is received by and a corresponding notch  354  when hanger assembly  340  is assembled and secured to an overhead support member. Each protrusion  316  and corresponding notch  354  pair form an engagement pair, in which one is an element of the engagement pair and the other is the corresponding or complemental element of the engagement pair. Accordingly, rim cover  302  is received in snap engagement with canopy  341 . Preferably, each notch  354  is circumferentially elongate thereby eliminating the necessity of precise alignment when fitting rim cover  302  about upper rim  351  of canopy  341 . 
         [0140]    As further seen in  FIG. 45 , when the hanger assembly  340  is assembled and installed, the upper edge  241  of rim cover  302  resides in juxtaposition with ceiling  250 , and lower edge  242  of rim cover  302  is in turned to reside in juxtaposition with canopy  341 , which is also shown in  FIG. 40 . Spacers  247  carried by rim cover  302  are positioned between rim cover  302  of upper rim  351  of canopy  341  and edges  248  of spacers  247  are received in juxtaposition with respect to upper rim  351  of canopy  341 , whereby spacers  247  interact between upper rim  351  of canopy  341  and rim cover  302  to set rim cover  302  at a substantially fixed circumferential spacing relative to upper rim  351  of canopy  341  as shown in  FIG. 44 . 
         [0141]    Referencing  FIG. 48 , each base  245  consists of upstanding finger  260 . Finger  260  has upper end  261  and opposing lower end  262  affixed to sidewall  240  of rim cover  302  at lower edge  242 . Finger  260  projects upwardly from lower edge  242  and terminates with upper end  261 , which is directed toward upper edge  241 . Finger  260  has front face  270  formed with protrusion  316 , and an opposing rear face  271  facing sidewall  240 , and there is a gap  272  therebetween. Beveled surface  274  is formed in front face  270  of finger  260  proximate to upper end  261  of finger  260 . Protrusion  316  is formed in front face  270  of finger  260 , and is located between beveled surface  274  and lower end  262 . Finger  260  is flexible, and flexes in reciprocal directions relative to sidewall  240  as indicated by the double arrowed line J in  FIG. 47 . The flexural character of finger  260  allows it to flex as needed for installing rim cover  302  to canopy  341  and removing rim cover  302  from canopy  341 .  FIG. 47  illustrates protrusion  316  as it would appear received by, extending through, and engaging notch  354  formed in upper rim  351  of canopy  30 . The flexural nature of finger  260  is also provided in such a way that finger  260  biases protrusion  316  toward and into and through notch  354  when installed therewith for providing a rugged and forcible engagement of protrusion  316  in and against groove  314 . Preferably, lower end  262  of finger  260  is integrally formed with sidewall  240 . The integral formation of lower end  262  of finger  260  with sidewall  240  is preferred, but it will be understood that lower end  262  can be welded to sidewall  240 , adhesively affixed to sidewall  240 , or rigidly affixed to sidewall  240  in other ways. 
         [0142]    To install rim cover  302 , rim cover  302  is brought upwardly toward upper rim  351  of canopy  341  and is maneuvered to register fingers  260  with notches  354 . With respect to each finger  260 , abutment  335  is initially received against beveled surface  274 . Through the application of an upward force, abutment  335  acts on beveled surface  274  deflecting finger  260  away from canopy  341  toward sidewall  240  permitting protrusion  316  to encounter a corresponding notch  354 , at which point finger  260  then deflects away from sidewall  240  toward notch  354  in canopy  341  snap receiving protrusion  316  into and through notch  354  suspending and securing rim cover  302  with respect to upper rim  351  of canopy  341 . Protrusion  316  is matingly receivable in notch  354  and is detachably receivable against and upon lower edge  360  of notch  354  between opposed side edges  361  and  361  to suspend rim cover  302  from canopy  341 .
