BACKGROUND
[002] Background description includes information that may be useful in understanding the present subject matter. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed subject matter, or that any publication specifically or implicitly referenced is prior art.
[003] Pedestal fans are a common household appliance that are used to move around within the house. As opposed to the ceiling fans, pedestal fans are portable and can be carried around the house easily. Additionally, the pedestal fans offer an advantage over other fans in a way that they can titled in the desired direction. Also, the pedestal fans can cover large area by oscillating about its standing axis.
[004] Conventional system used to oscillate the pedestal fans use complex mechanisms and are difficult to use. Thus, there is a need to simplify the oscillation process of the pedestal fan.

[0033] Referring to FIG. 1, disclosed is an oscillating mechanism 100 for oscillating a fan portion 602 (shown in FIG. 6) of a pedestal fan 600 (shown in FIG. 6). In an embodiment, the pedestal fan is a standing fan configured to be positioned on the floor or on the table (as a table fan).
[0034] The pedestal fan 600 may comprise a base portion 604 (shown in FIG. 6) and the fan portion 602, wherein the oscillating mechanism 100 is positioned between the fan portion 602 and the base portion 604. In an embodiment, the fan portion may comprise the fan blades located within the guard so that breeze is generated upon the rotation of the fan blades. In an embodiment, the base portion is configured to position the pedestal fan 600 on the floor or any surface as required by a user.
[0035] FIG. 2 discloses an exploded view of the oscillating mechanism 100, in accordance with an embodiment. The oscillating mechanism 100 comprises a first oscillating unit 202, a second oscillating unit 204, a cam unit 206, a motor 208 and a plurality of limiting nut 210.
[0036] FIG. 3 discloses an assembled view of the cam unit 206 and the motor 208. The cam unit 206 is configured to be received by the first oscillating unit 202 and the motor 208 is configured to be provided in the base portion 604. The cam unit 206 and the motor 208 are connected to each other such that the motor 208 is configured to rotate the cam unit 206. The motor 208 may comprise a spindle 306, wherein the spindle connects that cam unit 206 to the motor 208.
[0037] The cam unit 206 comprise a cam 302 and an oscillating rod 304. The cam 302 is circular in shape or may be elliptical. The spindle 306 is connected to one face of the cam 302 and the oscillating rod 304 is connected to the other face of the cam 302. The spindle 306 and the oscillating rod 304 are offset from the centre of the cam 302 such that the cam unit 206 rotates about a cam axis 308. This rotation of the cam unit 206 about the cam axis 308 allows the oscillating rod 304 to trace a circular path around the cam axis 308 due to the rotation of the spindle 306.
[0038] Referring to FIGs. 4A-4C, the first oscillating unit 202 is configured to be fixedly attached to the base portion 604 of the pedestal fan 600. The first oscillating unit 202 comprises a cam receiving hub 402. The cam receiving hub 402 is disposed between a central axis 102 (shown in FIG. 1) of the oscillating mechanism 100 and the perimeter of the first oscillating unit 202. The central axis 102 of the oscillating mechanism is the same as the central axis of the first oscillating unit 202 and the second oscillating unit 204.
[0039] In an embodiment, the cam receiving hub 402 is circular in nature and its diameter is smaller than the diameter of the cam 302 so that the cam 302 can rotate within the cam receiving hub 402. FIG. 4C specifically describes the cam unit 206 contained within the cam receiving hub 402. In an embodiment, the cam axis 308 and centre axis of cam receiving hub 402 are along the same line. This enables the cam unit 206 to remain within the cam receiving hub 402 about the cam axis 308 so that the perimeter of the cam 302 traces the inner circumference of the cam receiving hub 402.
[0040] Referring to FIG. 5, disclosed is an isometric view of the second oscillation unit 204. The second oscillating unit 204 is in contact or motional coupled with the first oscillating unit 202 and the oscillating rod 304 of the cam unit 206. The second oscillating unit 204 is configured to oscillate about the central axis 102, thereby oscillating the fan portion 602. The second oscillating unit 204 defines at least one tracing path 502 along the periphery. The tracing path 502 defines a groove 504. The length of the groove 504 determines the degree of oscillation of the second oscillating unit 204. The limiting nut 210 (shown in FIG. 2) is configured to be disposed within the groove 504 and fixed to the first oscillating unit 202. The second oscillating unit 204 defines an oscillating groove 506 which is configured to receive the oscillating rod 304. The oscillating groove 506 is along the radial direction of the second oscillating unit 204 and is transverse to the tracing path 502.
Working of the present subject matter
[0041] Referring to FIG. 6A, the oscillating rod 304 is at the topmost position within the oscillating groove 506. In an embodiment, the topmost position is the position within the oscillating groove 506 that is closer to the tracing path 502. In this position, the limiting nut 210 is at the centre of the groove 504. This positioning of the oscillating rod 304 indicates that the fan portion 602 of the pedestal fan 600 is in a neutral position means straight without any angular movement. Referring to FIGs. 6B-6C, the fan portion 602 is in neutral position.
[0042] In an embodiment, the oscillating rod 304 may be at the bottom position within the oscillating groove 506. In an embodiment, the bottom position is the position within the oscillating groove 506 that is closer to the central axis 102. In this position, the limiting nut 210 is at the centre of the groove 504. This positioning of the oscillating rod 304 indicates that the fan portion 602 of the pedestal fan 600 is in neutral position.
[0043] Referring to FIG. 7A, the oscillating rod 304 is at the centre position within the oscillating groove 506. In this position, the limiting nut 210 is at the ends of the groove 504. This positioning of the oscillating rod 304 indicates that the fan portion 602 of the pedestal fan 600 is oscillated towards the right or the left. In the instant embodiment, the second oscillating unit 204 is rotated in clockwise direction and the clockwise rotation is restricted using the limiting nut 210, thereby oscillating the fan portion 602 towards the left. The clockwise rotation of the second oscillating unit 204 is initiated by the motor 208. The motor 208 rotates that cam unit 206 within the cam receiving hub 402. The rotation of the cam unit 206 allows the oscillating rod 304 to rotate the second oscillating unit 204 by moving within the oscillating groove 506. The oscillating rod 304 moves inside the oscillating groove 506 and pushes the second oscillating unit 204 to oscillate around the central axis. The cam unit 206 continuously rotates within the cam receiving hub 402. The continuous rotation of the cam unit 206 may continuously rotate the second oscillating unit 204. However, the limiting nut 210 along with the groove 504, restricts the continuous rotation of the second oscillating unit 204 and instead allows it to oscillate, thereby oscillating the fan portion 602 with respect to the base portion 604 of the pedestal fan 600. Referring to FIGs. 7B-7C, the fan portion 602 is in left most position.
[0044] Referring to FIG. 8A, the oscillating rod 304 is at the centre position within the oscillating groove 506. In this position, the limiting nut 210 is at the ends of the groove 504. This positioning of the oscillating rod 304 indicates that the fan portion 602 of the pedestal fan 600 is oscillated towards the right or the left. In the instant embodiment, the second oscillating unit 204 is rotated in anti-clockwise direction and the anti-clockwise rotation is restricted using the limiting nut 210, thereby oscillating the fan portion 602 towards the right. Referring to FIGs. 8B-8C, the fan portion 602 is in right most position.
[0045] Figs 6 to 8 illustrate the exemplary working of the present subject matter. With the movement of the oscillating rod 304 inside the oscillating groove 506 pushes the second oscillating unit 204 to oscillate around central axis.
