The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF INVENTION
The present invention relates to the field of fan assembly. In particular, the present invention relates to a height-adjustable mounting configuration for adjusting height of positioning of a fan.
BACKGROUND OF THE INVENTION
Fans, such as pedestal fans or standing fans are very well known in the prior art.
Pedestal fans are useful in situations where portable fans are required with
adjustable air flow direction. Conventional pedestal fans include a height
adjustment mechanism mounted on a pipe of the pedestal fan. The fan switch
assembly and the upper assembly of the pedestal fan is usually mounted on this
pipe.
In addition, the fan switch assembly and/or the upper assembly is generally
fastened to the pipe by a collet with threads (can also be referred to as knob).
The knob is rotated to be loosened, allowing the pipe to slide up or slide down,
which in turn adjusts the height of the fan. After reaching the desired height, the
knob is again rotated in the opposite direction to lock the pipe, thereby locking
the fan in the desired height.
However, the knob needs to be loosened and tightened to adjust height.
Therefore, the conventional height adjustment mechanism is not hassle free. In
addition, there can be a limitation that the amount of adjustable height is limited.
The design of the height adjustment mechanism is also expensive.
In light of the above discussion, there is a need in the art for a height adjustment
mechanism that can overcome the limitations known in the art.

The height-adjustable mounting configuration 100 comprising a vertical member P. In addition, the height-adjustable mounting configuration 100 comprising an elongated bracket B including a first end portion and a second end portion. The first end portion fixedly carries the fan 3.
Further, the height-adjustable mounting configuration 100 comprising a bent-pipe unit R. The bent-pipe unit R includes parallelly extending first and second ends, and a bent portion therebetween, such that the first and second ends are fixed to the second end portion of the elongated bracket B, while the bent portion is at least partially engaged to the vertical member P.
Furthermore, a configuration of the fan 3, the elongated bracket B, and the bent-pipe unit R, is locked relative to the vertical member P, in a normally engaged configuration, whereas the configuration of the fan 3, the elongated bracket B, and the bent-pipe unit R, is capable of sliding relative to the vertical member P in a sliding configuration, upon at least partially tilting the configuration. The bent portion of the bent-pipe unit R comprises sequentially extending a first Z-shaped side section including a first end, a back section, and a second Z-shaped side section including a second end, such that the back section is raised relative to the first and second ends. Notably, the bent portion of the bent-pipe unit R is an integrated pipe unit, suitably bent to define the first Z-shaped side section, the back section, and the second Z-shaped side section.
The configuration of the fan 3, the elongated bracket B, and the bent-pipe unit R, can slide in the sliding configuration, for enabling adjustment of a height of

positioning of the fan 3.
The height-adjustable mounting configuration 100 further comprises a lock unit L
adapted to limit the adjustment of the height of positioning of the fan 3, in an
engaged configuration of the lock unit L, and allow the adjustment of the height
of positioning of the fan 3, in a released configuration of the lock unit L.
The lock unit L is adjusted to the released configuration, for enabling sliding of
the configuration relative to the vertical member P, and thus allowing adjustment
of the height of positioning of the fan 3.
The lock unit L is adjusted to the engaged configuration, for limiting sliding of the
configuration relative to the vertical member P, and thus limiting adjustment of
the height of positioning of the fan 3.
The lock unit L is a scissor-shaped unit comprising a first rod F and a second rod S
pivotally affixed to the first rod F with a pin P1. The lock unit L also comprising a
compressed spring S1 positioned between the first rod F and the second rod S. A
second end of the first rod F and a second end of the second rod S are released or
engaged relative to the vertical member P in the released configuration and the
engaged configuration, respectively. The compressed spring S1 maintains a
clamping force between the second end of the first rod F and the second end of
the second rod S around the vertical member P, in the engaged configuration
thereof.
The elongated bracket B is positioned perpendicular to the vertical member P.
In an embodiment, the second end portion of the elongated bracket B is slidably
engaged to the vertical member P, such that the elongated bracket B can slide
over body of the vertical member P. In one preferred embodiment, the fan 3 is
carried on top surface of the first end portion 1.
The lock unit L can be pressed or released manually by a user (not shown in
figures). When manually pressed, the lock unit L is in a released configuration,
thereby allowing the user to manually adjust the height of positioning of the fan
3. When released, the lock unit L is in the normally engaged position, thereby

limiting the sliding movement between the elongated bracket B and the vertical member P. In a preferred embodiment, the lock unit L is disposed below the elongated bracket B towards the base E (as shown in FIG. 2).
In an example, the user can manually apply force on the outer surface of a first end of the first rod F and the outer surface of a first end of the second rod S to enable the sliding mechanism of the elongated bracket B.
In a preferred embodiment, the parallelly extending first and second ends of the bent pipe unit R are welded to the elongated bracket B. In a first preferred embodiment, the parallelly extending first and second ends are disposed above the elongated bracket B. In a second preferred embodiment, the parallelly extending first and second ends are fixed at the sides of the elongated bracket B. In an embodiment, the elongated bracket B is a square pipe.
In an embodiment, the bent-pipe unit R is bent at an angle with the vertical member P, such that wobbling of the fan 3 is nullified during oscillation of the fan 3. In one example, the angle between the bent-pipe unit R and the vertical member P enables the elongated bracket B to take a support from the vertical member P.
The height-adjustable mounting configuration 100 enables the sliding mechanism to adjust the height of positioning of the fan 3. The height-adjustable mounting configuration 100 enables the sliding mechanism without the need of tighten or loosen anything, with facilitation of the lock unit L. The lock unit L ensures that the fan 3 is locked properly and does not slide down the vertical member P in the normally engaged configuration. In an example, the lock unit L acts as a child safety mechanism. In addition, the child safety mechanism ensures that the fan 3 is locked properly and does not fall even if the pedestal fan 200 is tilted. In a preferred embodiment, to adjust the height of positioning of the fan 3, the lock unit L is manually pressed by the user. Further, the user partially tilts (or slightly lifts) the elongated bracket B. The user may then slide the elongated bracket B over the vertical member P to reach the desired height. In particular,

the bent portion of the bent-pipe unit R slides over the vertical member P. The user may then release the lock unit L to lock the sliding mechanism between the elongated bracket B and the vertical member P. The user may then release the elongated bracket B to bring it back to its original position.
In an embodiment, a gasket is inserted between the bent-pipe unit R and the vertical member P. In an embodiment, another gasket is inserted between the lock unit L and the vertical member P. In an embodiment, yet another gasket is inserted between the elongated bracket B and the vertical member P. ADVANTAGES OF THE PRESENT INVENTION
