BACKGROUND OF THE INVENTION
(a) Technical Field of the Invention
The present invention relates to dusters, and in particular a
curved cleaning duster made of a plurality of non-weave cloth
layers and fiber yarn layers, a handle, a plate and a tenon. The
cloth has a curved shape. Thereby the duster can wipe objects
from different orientations.
(b) Description of the Prior Art
In the prior art duster, a cleaning cloth is engaged into a handle.
The handle has a hook for fixing the cloth. However, the
engagement of the cloth and handle by using the hook is not
sufficient to form a firm structure. Thereby in operation, the cloth
will loose from the handle. Moreover the cleaning cloth has only
one surface which has cleaning function. It makes an
inconvenient in cleaning. For a longer time, the user's waist will
feel ache.

spaced with a distance of 10 centimeter. The tenon has a bending
CA 02490769 2004-12-20
12
portion by inserting the post into the via hole so that the handle is
rotatable through 0 degrees to 360 degrees with respect to the plate.
The handle is connected to the plate so that the duster is a two-stage
device. The plate is a two stage device so that duster is a three-stage
device. The non-weave cloth is a general used weave cloth. The
curved plate is twisted through an angle between 90 degrees to 270
degrees.
The process of Fig. 2 will be described herein. The electric
static non-weave cloth layers (812) and smooth non-weave cloth
layers (812) are combined by a thermal process (803) to have net
like non-weave cloth (804). Then by cutting to form a texture net
non-weave cloth (806) of four layers. Then by combining (807)
two layers of layers (806) and by a process (509) of adding meltable
fiber yarns layers (808) to the cloth (806), a texture net non-weave
cloth (811) of six layers is formed. Then the cloth (811) is added
with electric static non-weave cloth layers (815). The layer (815)
is formed with nets (816) to have not form non-weave cloth layers
(817). Then the layers (817) are cut (818) to have strips (819) so
as to get a 8 layer structure (820). Then The 8 Iayer structure is
combined (830) with a handle and then is shaped (829) and then is
CA 02490769 2004-12-20
13
cut (827) and thermally processed (828) so as to get a product (826)
of the present invention.
It will be understood that each of the elements described above, or two or
more together may also find a useful application in other types of methods
differing from the type described above.
While certain novel features of this invention have been shown and
described and are pointed out in the annexed claim, it is not intended to be
limited to the details above, since it will be understood that various
omissions,
modifications, substitutions and changes in the forms and details of the
device
illustrated and in its operation can be made by those skilled in the art
without
departing in any way from the spirit of the present invention.
