Description
BACKGROUND OF INVENTION
[0001] This invention relates generally to mops and more
specifically to wet mops for housework. The mop comprise of a flat
rectangular mop head that can accommodate a replaceable mop sheet.
The mop sheet can use any washable fabric sheet or cloth as mop
sheet thus eliminate the dependence from using manufacture
specified mop sheet when current mop sheet wear out.
[0002] Mops with rectangular mop head, which utilize a mop sheet
for cleaning, are known in the art. Many structures have been
proposed in prior arts to secure the sheet to a rectangular mop
head. For example, U.S. Pat. No. 6,484,346 to Kingry et al and U.S.
Pat. No. 5,815,878 to Mrakami et al. show two different way to
secure the sheet to a rectangular mop head. However, these similar
mop arts invent their own structures to secure sheet instead of
utilizing most popular spring operated clip structures of well know
arts.
[0003] In addition, the above prior art need specially designed
cleaning sheet to fit in the claimed structures, thus provide more
cost and purchase hassle when replace worn cleaning sheet.
[0004] While U.S. Pat. No. 4,962,563 to Bacar claims a structure to
hold any type of rag, it is installed on an elongated mop head
instead of a rectangular mop head described in this invention.
SUMMARY OF INVENTION
[0005] Therefore, it is an object of this invention to provide a
mop that can use any easily acquired washable fabric sheet or cloth
as mop sheet, and easily to attach said mop sheet to said flat
rectangular mop head with the help of at least two spring operated
clips disposed on the top surface of said mop head.
[0006] It is another object of the invention to provide a mop which
can be used without worrying the hassle associated with shopping
for new manufacture specific refillable mop sheet after the current
one wear out.
[0007] It is also the object of the invention, as an option, for
manufactures to provide an universally acceptable cleaning sheet in
a simple rectangular shape, the sheet can be made of varieties of
material for customers of different needs.
[0008] Accordingly, a wet mop for use with fabric sheet of easily
obtainable as mop sheet is provided, comprising a flat rectangular
plate, an elongated handle pivotally connected to the plate, a
layer of foam attached to the bottom surface of the plate and at
least two saw teeth clips attached to the top surface of said plate
to secure the washable fabric sheet.
BRIEF DESCRIPTION OF DRAWINGS
[0009] FIG. 1 is a perspective view showing a floor mop according
to the present invention.
[0010] FIG. 2 is a view showing the manner of usage of the
demonstrated spring biased clip 6 of well known art. Many types of
spring operated clips can be used in this invention other than the
one demonstrated in FIG. 1.
[0011] FIG. 3 is a perspective view of the floor mop of FIG. 1,
wherein a sheet is attached to the mop head.
[0012] FIG. 4 is a perspective view of another preferred mop head
made in accordance with present invention.
[0013] FIG. 5 is an enlarged partial top view of the mop head of
FIG. 4, wherein the manner of usage of the spring operated clip 11
is shown.
DETAILED DESCRIPTION
[0014] A floor mop 1 shown by FIG. 1 in a perspective view
comprises a flat rectangular or plate-like head 2 and a stick 4
connected by a universal joint 3 of well known art to the head
2.
[0015] The head 2 comprises a upper part of body 5 made of hard
plastic material and an elastic plate layer 7 made of soft elastic
material such as foam or rubber covering the bottom of head 2. The
upper surface of the main body 5 comprises a centrally located pair
of transversely adjacent projections 8 for mounting of the
universal joint 3 and four spring biased clips 6 of well know art
preferably disposed at the corners. The spring biased clip 6 has a
saw teeth gripping jaw which are adapted to provide a rough
gripping surface so that a washable fabric sheet held between the
jaws of the clip is firmly secured in position, and said spring
operated clips is integral part of upper part of body 5. The
inherent spring force of each clip 6 causes the front portion of
the clips in close position. The marginal portion of the sheet used
as mop pad can be inserted into the clip 6 while clip jaw is opened
by pressing rear portion of the clip 6 so that the clip 6 can be
brought into engagement to hold the inserted marginal portion of
the mop sheet as the clip members are closed.
[0016] According to the embodiment of the invention exemplified in
FIG. 4 and FIG. 5, two elongated spring operated clips 11 are
disposed adjacent the longitudinal axis X of the mop head 2. The
clip 11 is a rectangular frame made from strong material such as
steel. The clip frames 11 are pivotally mounted along the
longitudinal axis X thereof on the top surface of mop head 2 so
that marginal portion of the mop sheet can be inserted between the
clip frame and the rough surface 9 of the mop head 2 after the clip
frame have been pivotally pulled to open upward and the clip frame
can be brought into engagement to hold the inserted marginal
portion of the mop as the clip members are closed. The spring
elements 10 shown in FIG. 4 and FIG. 5 are the source of the force
to keep the mop sheet in place. The rough surface 9, which is part
of the upper surface of the mop head 2, is used to help holding the
inserted marginal portion of the mop sheet tighter.
