Claims
1. An electric fan comprising: an annular frame; a blade assembly
disposed in the annular frame; an electric motor mounted in a
central portion of the blade assembly for rotating the blade
assembly; a plurality of sections releasably secured to an outer
edge of the annular frame; a louvered device rotatably mounted on
the motor; a front grill secured to the louvered device; and a rear
grill secured to a rear surface of the annular frame.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to mechanical fans and more
particularly to a wheel shaped novelty fan.
[0003] 2. Description of Related Art
[0004] A conventional novelty fan comprises a housing adapted to be
held by a user; a fan unit provided adjacent to an upper end of the
housing and being powered by a motor in the housing; a coupling
member attached to the housing at a lower end thereof such that the
user holds the housing between the fan unit and the coupling
member; and a switch positioned on an exterior surface of the
housing between the fan unit and the coupling member, thereby
allowing the user to selectively energize the motor and rotate the
fan unit while holding the housing.
[0005] Notwithstanding the novelty fan, the invention is neither
taught nor rendered obvious thereby.
SUMMARY OF THE INVENTION
[0006] It is therefore one object of the invention to provide an
electric fan comprising an annular frame; a blade assembly disposed
in the annular frame; an electric motor mounted in a central
portion of the blade assembly for rotating the blade assembly; a
plurality of sections secured to an outer edge of the annular
frame; a louvered device rotatably mounted on the motor; a front
grill secured to the louvered device; and a rear grill secured to a
rear surface of the annular frame.
[0007] The above and other objects, features and advantages of the
invention will become apparent from the following detailed
description taken with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] FIG. 1 is an exploded view of a first preferred embodiment
of a wheel shaped fan according to the invention;
[0009] FIG. 2 is a front view of the front grill;
[0010] FIG. 3 is a perspective view of the assembled wheel shaped
fan;
[0011] FIG. 4 is another perspective view of the assembled wheel
shaped fan;
[0012] FIG. 5 is an exploded view of a second preferred embodiment
of a wheel shaped fan according to the invention incorporating a
second configuration of the front grill;
[0013] FIG. 6 is a front view of a third configuration of the front
grill; and
[0014] FIG. 7 is a front view of a fourth configuration of the
front grill.
DETAILED DESCRIPTION OF THE INVENTION
[0015] Referring to FIGS. 1 to 4, a wheel shaped fan in accordance
with the invention comprises the following components as discussed
in detail below.
[0016] An annular frame 2 is provided with a blade assembly 1
therein. A motor 6 is mounted in a central portion of the blade
assembly 1 for rotating the blade assembly 1. Four resilient,
arcuate sections 4 each include a plurality of parallel groove 31
on an outer surface. The sections 4 are secured to an outer edge of
the frame 2 by fasteners (not numbered) to form a tire. A disc
shaped louvered device 5 is rotatably mounted on the shaft of the
motor 6. A front grill 7 is secured to the louvered device 5. A
rear grill 4 is mounted to a rear surface of the frame 2.
[0017] Referring to FIG. 5, a wheel shaped fan in accordance with a
second preferred embodiment of the invention is shown. The
characteristics of the second preferred embodiment are
substantially the same as that of the first preferred embodiment
except the following: The disc shaped louvered device 5 is
eliminated. The front grill 7 is replaced by its second
configuration of different shape.
[0018] Referring to FIG. 6, a third configuration of the front
grill 7, having a shape different that shown in the first and
section embodiments, is shown and referring to FIG. 7, a fourth
configuration of the front grill 7 having a shape different that
shown in the first and section embodiments is shown
respectively.
[0019] While the invention has been described in terms of preferred
embodiments, those skilled in the art will recognize that the
invention can be practiced with modifications within the spirit and
scope of the appended claims.
