BACKGROUND
Field
[0001] Embodiments of the present disclosure generally relate to a ceiling fan mounting
arrangement, and more particularly, to a support assembly with a boot attached to the ceiling for
frictionally engaging a vertical support frame of a ceiling fan.
Description of the Related Art
[0002] The background description includes information that may be useful in understanding
the present invention. It is not an admission that any of the information provided herein is prior
art or relevant to the presently claimed invention, or that any publication specifically or
implicitly referenced is prior art.
[0003] Ceiling fans have become increasingly popular in today's homes and businesses,
such as manufacturing areas, nursing homes, shops and restaurants. Ceiling fans in various forms
have been known for over a hundred years. These fans are desired, both, for their ability to move
air at low speed, and for their decorative effects. Ceiling fans are typically decorative because of
the slow motion of the fan blades, and because of the aesthetics of the fan itself. In the past,
ceiling boxes for supporting the fans were tested under static loads only. With the increasing
popularity of ceiling fans came the concern that dynamic loads of an unbalanced ceiling fan, jerk
due to start of motor, among other allied issues could cause mounting flanges of ceiling boxes to
flex and eventually break off.
[0004] Ceiling fan-mounting box is typically a hex shaped box with punch through holes
for electrical wire conduit pipe fitment. Internal to the box and projected out of the box on two
sides is a 10 to 12mm iron rod with a bent hook shape made in the rod for mounting the ceiling
fan, using attachments. Ceiling fans are mounted by means of components such as rubber boot,
mounting plate(s), down rod as shown in Figure 1A, 1B, and 1C respectively. Rubber boot, as
shown in Figure 1A, is a soft media interface between ceiling hook and down rod of the fan. A
metal plate or disk member, also commonly referred to as mounting plate, is adapted for
supporting and mounting a ceiling fan positioned over the open end of the box. Mounting plate is
a support element with openings as shown in Fig. 1B connected to a hanger bracket assembly
whereby a bolt adjacent their upper end passes through one set of openings. Down-rod is used
- 3 -
for attaching a ceiling fan motor shaft to mounting plate while providing a plurality of
connecting mechanisms for attaching electrical ground wiring to the down-rod. Ceiling fan
down-rod is typically an elongated tube of metal and provides a detachable connection between a
ceiling fan mounting assembly (mounting plate) and the motor shaft of a ceiling fan assembly.
Lower end of the mounting plates is adapted to the down-rod and is attached to it through the
lower set of holes in the mounting plate and the down-rod.
[0005] In terms of functionality, down rod is typically used for extending fan shaft of the
fan motor to reach the fan box along with holding the fan shaft by means of a bolt and nut
assembly as shown in Figure 2. Down rod is suspended from a hook or a fan box either within
the ceiling or mounted just below it. The down rod is free to swing so that the rod remains
vertical, even when hung from a sloped ceiling, allowing the fan motor and blades to maintain
the necessary horizontal orientation. Although the rod is free to swing, it is not free to rotate, so
that the fan does not rotate in place as a reaction to the torque generated by the motor. Down rod
is connected to the support assembly with various bolts such as bolt 250 that connects the
mounting plate 220 to rubber boot 210, bolt 260 that connects the mounting plate 220 to down
rod 230, and bolt 270 that connects down rod 230 to fan shaft 240, and as an extension shaft that
connects it to motor housing.
[0006] Fan boxes used in ceiling and installed during building construction also have
variations in hook diameter, generally noticed to be in the range of 10 to 12mm. As an example,
in old houses and rural areas, it is common to bend steel used in ceiling re-enforced concrete to
form the hook. In such cases, depending on the building/room span, the steel bar diameter may
vary. Generally it has been observed to be in the range of 8 to 12mm in diameter. Prior art rubber
boots supplied with fan are not capable of covering such wide variation in the hook and are
loosely mounted while accommodating smaller hook diameters. Such mounting is especially
inadequate to meet the demand of brushless motors.
[0007] With new upcoming technologies relating to brushless motors and high efficiency
motors, starting torque (Ts) is much higher than what is currently used by induction motors, Ts2 >
Ts1, as is demonstrated in the shape of graph for induction motor and PMDC/BLDC motor
shown in Figure 3. Therefore, at fan start-up, the motor has a tendency to give a jerk to the entire
mounting assembly, causing fan down-rod to experience a jerk, which is visible to user and, in
- 4 -
some cases, can also generate some noise at the time of fan start. Even during fan stop for
existing BLDC/ DC motors, permanent magnet in the motor also imposes jerks, wherein if there
is play in the fan mounting assembly, irritating noise can be produced when the fan is turned off.
[0008] There is therefore a need for a modified and accurate design of a rubber boot that
can engage hook properly with definite angle and can prevent jerks imposed by the motor.
Furthermore, there is also a need for a rubber boot, which can prevent down rod from
experiencing jerks and avoid generation of noise at the time of fan start.

DETAILED DESCRIPTION
[0035] In the following description, numerous specific details are set forth in order to
provide a thorough understanding of embodiments of the present disclosure. It will be apparent,
however, to one skilled in the art that embodiments of the present disclosure may be practiced
without some of these specific details. In other instances, well-known structures and devices are
shown in block diagram form.
[0036] Those of ordinary skilled in the art will realize that the following detailed
description of the exemplary embodiment(s) is illustrative only and is not intended to be in any
way limiting. Other embodiments will readily suggest themselves to such skilled persons having
the benefit of this disclosure. Reference will now be made in detail to implementations of the
exemplary embodiment(s) as illustrated in the accompanying drawings. The same reference
indicators will be used throughout the drawings and the following detailed description to refer to
the same or like parts.
[0037] The following discussion provides many example embodiments of the inventive
subject matter. Although each embodiment represents a single combination of inventive
elements, the inventive subject matter is considered to include all possible combinations of the
disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second
embodiment comprises elements B and D, then the inventive subject matter is also considered to
include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.
[0038] Figure 4 illustrates a fixture in the form of a ceiling fan assembly 400 in accordance
with an embodiment of the present disclosure. Assembly 400 can include a housing 410
containing motor (not shown) operatively connected with a ceiling of a building by means of a
down rod 440, wherein the rod 440 can be mounted to the ceiling in any known manner. It is
understood that electrical conductors extend from an electrical box (not shown) in the ceiling,
- 9 -
through the rod 440, and into the interior of the housing 410 where they are connected to a
conventional electrical motor. It is also understood that the motor contained in the housing 410 is
conventional, and, as such, can include a stator and a rotor assembly that includes an end casing,
a portion of which is exposed through an opening in the lower portion of the housing 410.
[0039] In an aspect, one or more elongated blades 430 can be mounted respectively to the
end portions of one or more corresponding mounting arms, wherein the mounting arms, in turn,
can be mounted onto the housing 410. The down rod 440 can be mounted with metal plates 450,
which can further house a rubber boot 460. Rubber boot housing can include one or more hooks
and slots used to mount the fan onto a ceiling. In an aspect, in order to mount the ceiling fan 400
to a ceiling, the down rod 440 can be configured/mounted with the ceiling in any known manner.
The installer can mount each blade 430 to its corresponding arm in a known or new manner, all
of which is within the scope of the present invention.
[0040] In an aspect, down rod 440 may be a rod instead of a hollow tub. Moreover, tubular
supporting components may be channeled and/or U-shaped in order to engage with one another
and to complete the holding arrangement. Although many other embodiments of the preferred
embodiment of the support can be envisioned, each is understood to be encompassed within the
spirit of the present invention and therefore, the present invention is not to be limited to the
description of the preferred embodiment.
[0041] Representation 450 shows how a hook rod passes through the fan box. It would be
appreciated that the proposed representation 450 is completely exemplary in nature and any other
construction can also be incorporated.
[0042] It is understood that variations may be made in the foregoing without departing
from the scope of the invention, and examples of some variations can include 1) change in the
number of blades 430, and therefore the number of arms and associated components discussed
above can vary within the scope of the invention; 2) change in the number of openings formed in
the flange and therefore the number of fasteners associated with each flange can be varied; 3)
change in that the blades 430 can be mounted to the arms in a manner different from that
described above; 4) change in that the arm portion, the flange, and guide pins known in the prior
art can be molded integrally or one or more of these components; 5) change in the material being
used to form the boot; 6) change in the configuration of the mounting flanges in the manner they
- 10 -
are connected to any part of the ceiling fan, other than the end casing, among other like changes.
Above mentioned embodiments are not limited to ceiling fans but are equally applicable to any
installation in which it would be advantageous to utilize the boot in the manner discussed above.
[0043] Figures 5A and 5B illustrate rubber boot design architecture 500 in accordance
with an embodiment of the present invention. Rubber boot architecture 500 can include a pair of
generally parallel, elongated support arms 502 and 504 having a fixed component 506 that can
join the parallel arms 502/504 with each other. In one aspect, the rubber boot 500 can have an
engaging portion 508 that can engage and/or wrap around the hooks of any size, such as ranging
from 10mm to 12mm in diameter. In another aspect, one or more projections 520 can be
incorporated on one or more outer sides of the proposed rubber boot/adapter design in order to
apply pressure onto the rubber boot to take shape around the hook. Such pressure can be applied
onto the projections by means of a bolt assembly that tightens the down rod (shown in Figure 6),
in effect of which projection(s) 520 on outer sides of the rubber boot are compressed, which can
enable in tightening the grip over the hook. In an implementation, the projections 520 can of any
desired shape such as curvilinear that best suits application of pressure by the bolt assembly with
respect to the hook.
[0044] In an aspect of the present disclosure, rubber boot 500 can include a slot 510 to
enable better gripping over the hook when compared with the gripping that takes place without
the slot. In yet another embodiment, inner projections 522 can also be incorporated into the
proposed rubber boot 500 to assist in clamping the hook within the rubber boot 500. Inner and
outer projection(s) can also provide adequate friction against the holding, thereby imparting
better grip to the holding assembly. In an alternative arrangement, rubber boot 500 may be
attached to a wall-engaging end in order to provide frictional resistance against a vertical surface
when the support arm of the fan is in a compressed state.
[0045] According to one embodiment, rubber boot 500 can be made up of rubber or any
other suitable resilient material. Figure 5B illustrates an arrangement showing the rubber boot
500 having compressed parallel arms so as to engage the hook. Design of rubber boot 500 can be
configured such that it accommodates all sizes of hooks ranging from 10mm to 12 mm diameter.
Such mounting slots can have a larger initial opening and a smaller sliding opening that can
extend in the same circumferential direction.

[0046] Figures 6A and 6B illustrate exemplary gripping of rubber boot assembly 600
around ceiling hook in compressed state, wherein the hooks rods of both 6A and 6B have
different dimensions/diameters. Assembly 600 can include a rubber boot 610, a metal plate
assembly 620, one or more bolts 630, rubber sleeve(s) 640, down rod 650, a slot 660, and hook
680. Representation of Figure 6A shows gripping of hook 680 being performed by the rubber
boot 610 by means of arms of the boot 610, which are inclined at an angle of β with respect to
the support structure. Figure 6B illustrates an even smaller angle β for tightening the grip over
the hook 680 having relatively smaller dimension, which in one exemplary implementation, can
be done based on diameter of the hook. In an implementation, tightening of bolts and nuts 630
enables metal plate assembly 620 to be tightened as well, thereby pushing the boot 610 inwards
by means of outer projections 670 on the boot 610. In an aspect, slot 660 can allow rubber boot
610 to compress the hook more than the rubber boot would have done without such a slot, as the
gap provided in the slot allows the resilient material to compress in the direction of applied
pressure. Due to such applied pressure, there is no change on the hardness of the resilient
material used for the rubber boot making when the pressure is applied to the rubber boot for
compression, the flexibility allows effective gripping around the hook according to the
embodiment of the present invention. The compression state of rubber boot can be brought about
by tightening the down rod bolt 630, which makes the metal plate to come closer pushing the
rubber boot inwards and thus making the angle “β” between the metal plate 620 and rubber boot
610 and encompassing the hook by >180 degree, depending on the hook diameter. The
compressed state of rubber boot can be kept permanent till the whole assembly is disengaged,
thereby not allowing the down rod 650 to jerk.
[0047] In another embodiment, mounting metal plate 620 can cover the parallel walls of
the rubber boot and can be compressed or adhered or pressurized towards each other using the
bolts 630, which can be screwed in the openings of the metal plate 620 at one end. The other end
of the metal plate 620 can include a different opening, which can be fed with another bolt 630 to
hold down rod 650 in a holding arrangement. In an aspect, the ceiling metal plate 620 can have a
large circumferential area at its first end, and a small circumferential area at the second end.
Ceiling metal plate 620 can be of any shape and size depending on the requirement, and can
include at least two plates either attached with spring suspension or with bolts etc.
- 12 -
[0048] In an embodiment, down rod 650 can be extended from ceiling to housing
containing motor and other hardware parts. Down rod 650 can be a hollow tube or solid rod,
which can connect the one end holding arrangement to the other end holding arrangement. The
down rod 650 can provide a detachable connection between a ceiling fan mounting assembly and
the motor housing of a ceiling fan assembly, wherein the mounting assembly can include
connectors such as screw or bolts, at least one ground wire (not shown) for attachment to the
down rod 650 for electrical grounding of the down rod 650, and ceiling fan mechanisms attached
to the down rod 650. Length of the down rod 650 may vary in accordance with the size of the
ceiling fan to be installed, and further in accordance with length of any additional support fan
shaft required for installation of the ceiling fan. Internal diameter of interior void of the down rod
may vary in case if the down rod 650 is hollow in nature. The down rod 650 of the present
invention can provide versatility for attachment of electrical ground wires, which is important for
the present invention to provide a standardized down rod 650 that may be utilized for connecting
a high percentage of the various designs of ceiling mounting assemblies and other elements
distributed by the ceiling fan industry.
[0049] In an embodiment, ceiling fan can have a motor having a housing therearound, and
can have an upwardly extending fan shaft designed to attach to a hanging down rod 650 from the
ceiling of a room in a building. The fan can be attached to the motor so that the blades are rotated
by the motor around the center portion of the fan motor to allow a fan shaft to extend below the
motor housing. This fan shaft can be non-rotating and can be provided to pass electrical wires
there through for attaching a lighting fixture or the like. Electrical lines for connecting to the fan
motor can pass through the vertically extending shaft through the passageway (not shown) in the
adapter, where they can then connect the switches that are switched from cord to drive the
electric motor.
[0050] Figures 7A and 7B illustrate positions of rubber boot assembly 700 before
tightening the boot with respect to the down rod in accordance with an embodiment of the
present application. As can be seen, metal plate 720 is not mounted or fastened with down rod
730 and the plate 720 merely rests on the external projections 740 of the rubber boot 710. The
resting position of the metal plate 720 makes the angle “α” with the walls of rubber boot 710
before the fastening of the plate 720 with the down rod 730.
- 13 -
[0051] One should appreciate that although the present disclosure has described coupling
of different components by means of a nut and bolt assembly, any other suitable coupling
arrangement can be incorporated in the proposed adapter architecture. For instance, instead of
bolt/nut assembly, split pin architecture can also be incorporated. Other known arrangements
such as pins, rivets, lock nuts, among others can also be incorporated.
[0052] It is understood that the specific order or hierarchy of steps in the methodology
disclosed is an illustration of exemplary approaches. Based upon design preferences, it is
understood that the specific order or hierarchy of steps in the processes may be rearranged. Some
of the steps may be performed simultaneously. The accompanying method claims present
elements of various steps in a sample order, and are not meant to be limited to the specific order
or hierarchy presented.
[0053] There may be many other ways to implement the invention. Various functions and
elements described herein may be portioned differently from those shown without departing
from the spirit and scope of the invention. Various modifications of these embodiments will
readily apparent to those skilled in the art in view of present disclosure, and generic method
defined herein may be applied to other embodiments.
[0054] All structural and functional equivalents to the elements of the various
embodiments of the invention described throughout the disclosure that are known or later come
to be known to those ordinary skilled in the art are expressly incorporated herein by reference
and intended to be encompassed by the invention.
[0055] The above description and drawings are only illustrative of preferred embodiments,
which achieve the objects, features and advantages of the present invention, and it is not intended
that present invention be limited thereto. Any modification of the present invention, which
comes within the spirit and scope of following claims, is considered part of the present invention.
Furthermore, to extent that the term “include”, “have” or like is used in the description or the
claims, such term is intended to be inclusive in manner similar to the term “comprise” is
interpreted when employed as a transitional word in claim.
[0056] As used herein, and unless the context dictates otherwise, the term "coupled to" is
intended to include both direct coupling (in which two elements that are coupled to each other
- 14 -
contact each other) and indirect coupling (in which at least one additional element is located
between the two elements). Therefore, the terms "coupled to" and "coupled with" are used
synonymously. Within the context of this document terms "coupled to" and "coupled with" are
also used euphemistically to mean “communicatively coupled with” over a network, where two
or more devices are able to exchange data with each other over the network, possibly via one or
more intermediary device.
[0057] It should be apparent to those skilled in the art that many more modifications
besides those already described are possible without departing from the inventive concepts
herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the
appended claims. Moreover, in interpreting both the specification and the claims, all terms
should be interpreted in the broadest possible manner consistent with the context. In particular,
the terms “comprises” and “comprising” should be interpreted as referring to elements,
components, or steps in a non-exclusive manner, indicating that the referenced elements,
components, or steps may be present, or utilized, or combined with other elements, components,
or steps that are not expressly referenced. Where the specification claims refers to at least one of
something selected from the group consisting of A, B, C …. and N, the text should be interpreted
as requiring only one element from the group, not A plus N, or B plus N, etc.
