An Oscillator Mechanism Of A Wall Mounted Fan

Abstract: An oscillator mechanism (1) of a wall mounted fan comprising a fan motor mounted in a fan housing and having its shaft extending inwardly and disposed for rotation about a horizontal axis and a plurality of fan blades mounted on the fan shaft in radially spaced apart relationship- The oscillator mechanism comprises a helix gear (2) mounted for rotation about a vertical axis outside the fan housing (3) at the back thereof in mesh with a worm gear (4) mounted on a shaft extension (5) outwardly co- axially extending from the fan shaft. A spindle (6) is disposed within the hub (7) of the helix gear for rotation about a vertical axis and having a locking head (8) at the top thereof. The locking head is spring (9) biased towards the upper end of the hub of the helix gear. The locking head and the hub of the helix gear are adapted (10,11) to interlock each other. The spindle has a pinion (12) mounted at the lower end thereof in mesh with a spur gear (13) mounted for rotation about a vertical axis at the back of the fan housing. A horizontally disposed rocker lever (16) has its one end pivoted to the fan housing and the other end eccentrically pivoted on the spur gear. A tripping lever (19) is horizontally disposed in the proximity of the locking head of the spindle and pivoted at the centre thereof with its one end engaged against the locking head adapted to lift the locking head against the spring tension and allow the locking head to move down under expansion of the spring and a linear actuator assembly (22A) is connected to the other end of the tripping4ever.

PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the nature of this invention

FIELD OF INVENTION
The invention particularly relates to pull cord mechanism for controlling oscillation of fan.
BACKGROUND OF INVENTION
Conventionally an oscillation mechanism in wall mounted fans with integral gear box is controlled by an oscillation control lever. The user controls the oscillation mechanism through a lever which is to be moved from left to right to activate the oscillation of motor. Since wall mounted fans are mounted at a height it is little inconvenient for the user to activate/ deactivate the mechanism. Also the lever gets bend during activation process.
In the proposed invention lever Mechanism is eliminated by novel pull cord mechanism to overcome the drawbacks identified in prior art.
OBJECTS OF INVENTION
An object of the invention is to provide a pull cord mechanism to control an oscillation mechanism in wall mounted fans.
Another object of the invention is to provide a pull cord mechanism for a user to operate conveniently by sitting on the floor


Another object of the invention is to provide a pull cord mechanism which is simple in construction also cost effective
Another object of the invention is to provide a pull cord mechanism which is compact and take less space.
Another object of the invention is to provide a pull cord mechanism having flexibility to adjust the height of cord to control from various requirements.
DETAILED DESCRIPTION OF THE INVENTION
This invention relates to a pull cord mechanism which will activate the oscillation. Once string is pulled, oscillation will be ON. Again pulling of cord will deactivate the oscillation mechanism. The pull cord mechanism consists of a pair of worm gear and pinion gear arrangement for effecting the pullover. A wire use to connect one end of the motor to other send of the pinion shaft, while the other end of the pinion shaft is connected with the pull cord. When the pull cord mechanism is activated / deactivated, the pinion portion of the shaft which in meshing with worm gear .
In accordance to the present invention is to provide, a pull cord mechanism consists of handle with pull cord


In accordance to the present invention is to provide a pull cord mechanism consists pair of worm gear and pinion gear arrangement for effecting the pullover.
In accordance to the present invention is to provide, a pull cord mechanism consists wire use to connect one end of the motor to other send of the pinion shaft, while the other end of the pinion shaft is connected with the pull cord.
In accordance to the present invention is to provide, a pull cord mechanism consists of pinion shaft which in meshing with worm gear to activated / deactivated the oscillation
