Applicant(s): Actual Inventor(s): Address for Service: HUNTER FAN COMPANY RICHARD A PEARCE PATENT ATTORNEY SERVICES 26 Ellingworth Parade Box Hill Victoria 3128 Australia Title: MOUNTING SYSTEM FOR SUPPORTING A CEILING FAN ASSEMBLY The following statement is a full description of this invention, including the best method of performing it known to me/us:- 00 1A 00 MOUNTING SYSTEM FOR SUPPORTING A CEILING FAN ASSEMBLY TECHNICAL FIELD This invention relates to a mounting system for supporting a ceiling fan assembly.
BACKGROUND OF THE INVENTION Ceiling fans have become an increasingly popular supplementary means of creating an airflow within both commercial and residential buildings. Notwithstanding the widespread use of ceiling fans, the installation and subsequent stabilization of ceiling fans during use remains problematic.
m'
I
^1- ^1problematic.
00 OC -2- With conventional mounting systems, the weight of the ceiling fan assembly, which includes the ceiling fan motor, motor housing, downrod, blades and blade irons, is supported by either a mounting bracket or a canopy. These mounting brackets or canopies typically include slotted C1 openings extending from their outer edges to their centers, 00 Swhich are adapted to accept and retain the top end of the downrod which commonly ends in a ball joint.
When a bracket mounting system is used, the slotted mounting bracket is mounted either directly or indirectly to the ceiling at the mounting location of the anticipated connection of the ceiling fan assembly to the electrical current supply. The downrod is positioned within the slotted opening with the ball joint positioned above the slotted opening so that the downrod may be slid along the slotted opening to the mounting bracket's center and then lowered so that the ball nests upon the mounting bracket.
Thus, the weight of the ceiling fan assembly is supported by the mounting bracket through the ball joint. The ceiling fan assembly is then wired to the electrical power supply wires within the ceiling. Throughout installation and wiring of the ceiling fan assembly, the canopy rests on or above the ceiling fan motor housing with the downrod extending through the center opening of the canopy. After wiring is completed, the canopy is manually raised along the downrod and is mounted to the mounting bracket to hide the mounting bracket and electrical wires from view.
When a canopy mounting system is used, the canopy is mounted either directly or indirectly to the ceiling at the mounting location of the ceiling fan assembly to the electrical current supply in much the same manner as previously described in reference to the mounting bracket.
The downrod is then placed within the slotted opening of the canopy and is slid to the center of the canopy which is 00 S-3adapted to accept and retain the downrod ball joint. Thus, s the weight of the ceiling fan assembly is supported by the mr canopy through the ball joint. Working through the slotted opening in the- canopy, the installer wires the ceiling fan assembly to the electrical wires within the ceiling. A cover is then mounted to cover the opening and form a Scomplete canopy.
0 C These conventional mounting systems, however, may 0 include a gap between the ball joint and mounting bracket C 10 that may cause the ceiling fan to wobble. These gaps may be created through slight differences between the shape or size of the ball joint and the mounting bracket or canopy.
It thus is seen that a need remains for a mounting system that enables the ball joint and mounting bracket or canopy to fit together in a better manner. Accordingly, it is to the provision of such that the present invention is primarily directed.
The above references to and descriptions of prior proposals or products are not intended to be, and are not to be construed as, statements or admissions of common general knowledge in the art in Australia.
SUMMARY OF THE INVENTION In a preferred form of the invention a mounting system for supporting a ceiling fan assembly of the type having a motor, motor housing, a plurality of blades and a downrod to a support surface. The mounting system comprises a mounting plate configured to be mounted to a support surface, a hanger coupled to the mounting plate and having a receiving flange, and a ball joint coupled to an end of the downrod. The ball joint is configured to be received within the hanger receiving flange. The ball joint has an exterior surface with a .plurality of deformable ridges configured to contact the hanger receiving flange. With this construction, the deformation of the ridges creates a greater fit between the ball joint and the hanger receiving flange.

DETAILED DESCRIPTION With reference n30 bracket 21 coupled to the mounting plate 14. Ths, there is shown in21 hasFig. 1 atwo mounting yarms 22 and0 and conventional ceilholding flange, cradle, or nest 23 spanning the bottom ends a preferred form of the invention, shown arms 22. The ball holding flsystem 0 in an ge 23 h as a bevele for clarity of explanation. The mounting system i0 includes an pre-mounted upper assembly 12 and a lower hanging assembly 13. The upper pre-mounted assembly 12 includes a mounting plate 14 with an annular array of mounting slots 15 therein and a peripheral rim or flange 16 having threaded mounting holes 17 therein. The upper assembly 12 also includes moun t ing screws 18 which are sized and shaped to pass through the mounting slots 15 and into the ceiling C.
The upper assembly 12 also includes a hanger or hanger bracket 21 coupled to the mounting plate 14. The hanger 21 has two mounting arms 22 and a stepped ball holding flange, cradle, or nest 23 spanning the bottom ends of the mounting a rms 22. The ball holding flange 23 has a beveled 00 ct interior facing surface 24. The ball holding flange 23 also includes an opening 26 therein which allows the passage of the downrod therethrough during mounting, as described more hereinafter.
The lower hanging assembly 13 includes a downrod 29 0 coupled to a ball joint 31 and a canopy 32 journalled upon 00 the downrod 29. The term ball joint is intended to represent the enlarged portion atop the end of the downrod represented in the illustrations and is not intended to be limited to a sphere, as the ball joint may also include partial spheres, oblong or oval shapes, or symmetrical or asymmetrical structures such as the trilobular ball structure shown in U.S. Patent No. 6,872,054. The downrod 29 has the ball joint 31 fixed to its upper end and the ceiling fan assembly 11 coupled to its lower end. The ball joint 31 is configured to be received within the hanger ball holding flange 23. The ball joint has a series of Vshaped vertical ridges 33 that extend from the lower edge to the upper edge of the ball joint.. In the preferred embodiment, the ridge height is approximately 0.02 inches with the apex or bight of the V-shaped ridge being directly outwardly. The ball joint is made of nylon, such as catalog no. 101L rated 94V-2 made by E.I. DuPont de Nemours and Company, which enables a portion of the ridges 33 to be worn or deformed easily.
The canopy 32 includes a central, stepped flange adapted to receive and nest flushly against the exterior of the hanger ball holding flange 23. The lower hanging assembly 13 also includes mounting screws 37 adapted to extend through corresponding slotted mounting holes 38 in the canopy 32 and be threadably received within the corresponding threaded mounting holes 17 in the mounting plate flange 16. A canopy ring 39 is adapted to be coupled to the top end of the canopy 32 to obscure the mounting 00 F1 -6- M screws 37 from view.
The ceiling fan assembly 11 has an unshown motor, a motor housing 46, fan blades 47, and blade irons 48. The ceiling fan motor extends through an opening at the lower O 5 end of the motor housing 46. The ceiling fan blades 47 are 0 coupled to blade irons 48 which are in turn coupled to the 00 motor at predetermined locations depending on the desired number of fan blades 47. Although the ceiling fan assembly 11 is shown in the preferred embodiment with five blades 47, any number of fan blades 47 may be used as dictated by convention. Thus, rotational motion produced by the motor will produce air circulation through rotational movement of the fan blades 47. In order to control the speed of rotation of the fan blades 47, the motor has an unshown control switch which can be controlled conventionally through actuation of a pull string or electrical controller.
In use, the upper pre-mounted assembly 12 is installed by mounting the mounting plate 14 to the ceiling C. The mounting plate is mounted to the ceiling by extending the mounting screws 18 through the screw slots 15 in the mounting plate 14 and threading the screws 18 into the ceiling, ceiling joists or electrical box mounted to a ceiling structure or the like.
As shown in Fig. 3, the lower hanging assembly 13 is then suspended from the upper pre-mounted assembly 12 by positioning the ball joint 31 within the hanger ball holding flange 23. The ceiling fan assembly 11, specifically the unshown electric wires associated with the electric motor, is then wired to the electrical wires in the ceiling. It should be noted that the installer may couple the wires without lifting the ceiling fan assembly 11 or maintaining the relative position of the ceiling fan assembly 11.
00 F1 S-7- O Next, the canopy 32 is raised along the downrod 29 to a position generally below and adjacent the mounting plate 14. With the threaded screws 37 mounted within the threaded screw holes 17 of the mounting plate flange 16 the canopy is raised so that the heads of the screw 37 pass through the large portion of the slotted mounting holes 38.
00 0The canopy is then rotated clockwise so that the heads of Sthe screw 37 are positioned in the narrow portion of the mounting holes 38 and tightened to prevent the canopy from falling. The canopy and mounting plate may also include a circular mounting hole 49 and corresponding screw 50 which further prevents the canopy from rotating counterclockwise and thereby releasing from the mounting plate.
During operation of the ceiling fan slight vibrations and other movements cause the ball joint 31 to move relative to the hanger ball holding flange 23. This movement and the weight of the fan itself cause the Vshaped ridges 33 of the ball joint to be worn down or deformed. The term deformable used herein is intended to mean the wearing away of, compression, or physical deflection of the ridges. This deformation of the ridges 33 causes the ball joint 31 to fit tight within the holding flange 23, even correcting some tolerance discrepancies between such. The ridges of the preferred embodiment are intended to be worn approximately 0.01 inches wherein the ridge becomes wider resulting in a reduction of its wearing. As such, the ball joint ridges 33 allows for a better fit between the ball joint and the holding flange, an improvement over the prior art wherein variations therebetween may cause fit related problems between the smooth surfaces of the ball joint and their receiving member.
With reference next to Fig. 4, there is shown a mounting system having a ball joint 60 in another preferred 00 Cq -8form of the invention. Here, the ball joint 60 has ridges 61 oriented in a generally horizontal direction, as opposed to the vertical orientation previously described. The horizontal ridges deform as previously described. The terms vertical and horizontal are intended to refer to a general direction of orientation.
With reference next to Fig. 5, there is shown a 00 mounting system having' a ball joint 70 in another preferred form of the invention. Here, the ball joint 70 has ridges C' 10 that form a field of protrusions or pads 71, as opposed to the vertically orientated elongated previously described.
The pads deform as previously described. The ridges here are also truncated rather than having a sharp ridge line or apex.
It should be understood that the hanger may be configured to be mounted directly to a support surface without the need for a separate mounting plate.
It should also be understood that the concept of deformable ridges may also be incorporated into a mounting system 80 wherein the ball joint 81 resides within the beveled flange or ball receiver 82 of a canopy 83, a system wherein the ball joint is coupled to the canopy rather than the hanger, as shown in Fig. 6. As such, the canopy may be referenced as the hanger.
It thus is seen that a mounting system for supporting a ceiling fan assembly is now provided which compensates for tolerance differences between the ball joint and the ball joint holding flange. It should be understood that many modifications may be made to the specific preferred embodiment described herein without departure from the spirit and scope of the invention as described by the following claims.
When used in this specification and claims, the terms "comprises" and "comprising" and variations thereof mean that the specified features, steps or integers are included. The terms are not to be interpreted to exclude the presence of other features, steps or components.
