invention, or that any publication specifically or implicitly referenced is prior art.
[003] Ceiling fans are extensively used in homes and offices for air circulation.
Especially, in tropical countries like India ceiling fans are widely used by people
as they are cheap and affordable. Further, regulators are provided in the ceiling
fan to control speed of the fan in accordance with the temperature of the
atmosphere. User can change the speed of the fan by rotating the knob of the
regulator. The speed option of the regulators depends upon the circuitry used in
the regulator. For ex- maximum speed option in a regulator follow relation:
N= 2n +1 wherein n = number of capacitors used in the assembly.
[004] A typical regulator comprises a circuitry to optimize voltage given to the
fan motor, a regulator housing to accommodate the circuitry and a knob to provide
an input to the circuitry, to set the fan at desired speed. All the regulators available
in the market today have the knob protruded outside the regulator housing.
25 [005] There is always a possibility of the knob of the ceiling fan regulator
getting damaged/tempered by small kids in house while operating in wrong ways.
Further, the knob gets damaged during constructional work or white wash going
on in the houses or offices.

[0051] Referring to Figure 1a and 1b illustrating isometric view and sectional
view, respectively, of the dual functioning fan regulator 100 according to one of
the embodiments of present subject matter. The present subject matter describes a
dual functioning fan regulator 100 having a knob 102 which can be rotated to vary
20 the speed of the fan as well as pushed in and pushed out of a regulator housing
101. The dual functioning fan regulator 100 comprises a fan regulator housing 101
having a circuitry 103 to optimize voltage given to fan motor to control speed of
the fan and a knob 102 to provide input to the circuitry. The knob 102 is
connected to the circuitry 103 through a translational-rotary mechanism 200. The
25 knob 102 performs, rotary operation to provide input to the circuitry 103 which
subsequently change the speed of the fan in accordance with the input, and
translational motion to get inside and outside of the ribs housing 101.
[0052] Referring to Figure 2 illustrating exploded view of the dual functioning
fan regulator 100 according to one of the embodiments of present subject matter.
30 The translational-rotary mechanism 200 which is provided to connect the knob
9
102 with the circuitry 103 inside the regulator housing 101 includes a fixed clamp
201 which is provided in connection with the circuitry 103, a ribs housing 202, a
cam 203 and a plunger 204. The ribs housing 202 has two types of guides
provided on the inner side of the ribs housing 202. The bottom side of the cam
5 203 faces the fixed clamp 201 and has teeth pointing upwards. The cam is
provided in the bottom of the ribs housing 202. The plunger 204 has downward
pointing teeth on its bottom and its top is connected to the knob 102. The plunger
204 is provided in the top side of the ribs housing 202, in a way, that when the
knob 102 is pressed teeth of the plunger 204 gets engaged with the teeth of the
10 cam 203.
[0053] Referring to Figure 3a, 3b and 3c illustrating isometric view, sectional
view and inside view, respectively, of ribs housing 202 used in the dual
functioning fan regulator 100 according to one of the embodiment of present
subject matter. The ribs housing 202 is a component of the translational-rotary
15 mechanism which accommodates the cam 203 in the lower portion and the
plunger 204 in the upper portion. Protrusions 301 are provided on the outer lower
surface of the ribs housing 202 to fix the ribs housing 202 with the fixed clamp
201 connected to the circuitry 103. The inner surface of the ribs housing 202 has
guides 302, 303 to guide the motion of the cam 203 and the plunger 204 inside the
20 ribs housing 202. There are two types of guides 302, 303 provided inside the ribs
housing, namely, through guides 303 and locking guides 302. The through guides
303 restrict the rotary motion of the cam 203 and the plunger 204 inside the ribs
housing 202 and the locking guides 302 locks the cam 203 on the lower portion of
the ribs housing 202.
25 [0054] Referring to Figure 4a and 4b illustrating isometric view and sectional
view, respectively, of cam 203 used in the dual functioning fan regulator 100
according to one of the embodiment of present subject matter. The cam 203 is
provided inside the bottom side of the ribs housing 202 wherein the bottom side of
the cam 203 is always in contact with a spring 601 having its other end connected
30 to the provision provided in the fixed clamp 201. The upward pointed teeth of the
10
cam 401 are provided on the outer bottom side of the cam 203. The teeth 401
make a sliding angle with the horizontal in the range of 30o to 35o. Further,
projections 402 are provided on the upward teeth 401 which engages with the
guides 302, 303 inside the ribs housing 202. The engagement of projections 402
5 with the through guides 303 ensures that cam 203 does not rotate inside the ribs
housing 202. Further, the projections 402 also engage with the locking guides 302
to lock the knob 102 inside the regulator housing 101.
[0055] Referring to Figure 5a and 5b illustrating isometric view and sectional
view, respectively, of plunger 204 used in the dual functioning fan regulator 100
10 according to one of the embodiment of present subject matter. The plunger 204 is
provided in the top side of the ribs housing 202 with its one end connected to the
knob 102. The downward pointed teeth 501 are provided at the bottom of the
plunger 204 to engage with the upward pointing teeth 401 of the cam 203 (shown
in figure 7). The teeth 501 of the plunger 204 also make a sliding angle with the
15 horizontal in the range of 30o to 35o. Further, projections 502 are provided on the
plunger 204 to engage the plunger 204 with the guides 303 inside the ribs housing
202. The projections 502 of the plunger 204 only engage with the through guides
303 inside the ribs housing 202. The engagement of the projections 502 with the
through guides 303 restrict the rotary motion of the plunger 204 inside the ribs
20 housing 202.
[0056] The dual functioning fan regulator 100 of the present subject matter
provides two toggling positions to the knob 102, namely, Pushed-in and Pushedout.
[0057] Referring to Figure 6 illustrating components of translational-rotary
25 mechanism 200 in outermost position (Pushed-out position). After setting the
speed of the fan in Pushed-out position of the knob 102, the knob 102 is pressed
to set the knob 102 in Pushed-in position. The knob 102 subsequently pushes the
plunger 204 inside the ribs housing 202 and the teeth 501 of the plunger 204 gets
engage with the teeth 401 of the cam 203. Due to the engagement of projections
30 402, 502 of the cam 203 and the plunger 204 with the through guides 303 the cam
11
203 starts to move downwards (translation motion only) towards the fixed clamp
201 without rotating. As soon as the bottom portion of the cam 203 comes out of
the ribs housing 202 the cam 203 starts to rotate and gets locked in the locking
guides 302. This locking of the teeth 401 of the cam 203 with the locking guides
5 302 of the ribs housing 202 sets the Pushed-in position of the knob 102.
[0058] Referring to Figure 8 illustrating components of the translational-rotary
mechanism 200 during locking state of the cam 203 with the ribs housing 202. To
change the speed of the fan again, the knob 102, which is in the Pushed-in
Position, is pressed. Due to pressing of the knob 102, the cam 203 disengages
10 with the locking guides 302 of the ribs housing 202 and gets unlocked. The spring
601 which is always in contact with the bottom side of the cam 203 pushes the
cam 203 in upward direction. The cam 203 subsequently pushes the plunger 204
in upward direction which in turn pushes the knob 102 outside the regulator
housing 101.
15 [0059] The speed of the fan is adjusted by rotating the knob 102. The knob 102
gives the input to the circuitry 103 through the translation-rotary mechanism 200
described above. The knob 102 is rotated which subsequently rotate the
translation-rotary mechanism 200 connected to the circuitry 103 through the fixed
clamp 201.
20 [0060] The dual functioning fan regulator 100 of the present subject matter
provides two toggling positions to the knob 102, namely, Pushed-in and Pushedout.
This gives more safety to the knob 102 of the fan regulator 100, as when not
in use the knob 102 can be pushed inside the fan regulator housing 101. Further,
the possibility of damaging the knob 102 due to wrongful handling by the kids is
25 evaded.
