Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to the field of washing devices for clothes and the like and, in particular, to a manually operated washing device.
2. Description of Related Art
The automatic washing machine is universally accepted as the most practical home clothes cleaning device. However they are expensive and require electrical power. This rules out their use in areas where there is no readily available electrical power, which is particularly the case in the poorer third world countries. What makes these powered washing machines effective is the cleaning action of the agitation system. In the top loading machines, the back and forth rotation of a finned central column or its up and down motion circulates the soapy water through the soiled clothes removing the dirt and/or stains. In the front loading machines, it is the tumbling action caused by the fins mounted within the drum.
Many manually operated devices for washing clothes and the like are also effective, for example, the corrugated washing board. However, its use requires a great deal effort. An individual must remove the wet clothes from the tub and “rub” the clothes across the corrugated washing surface. Some what less effective are the numerous manually operated rotating drum type devices where the clothes, soap and water are added to the drum and a hand crank is used to rotate it. Both vertical and horizontal rotating drums are available. However, these are generally limited in size for use on tabletops. If they become much larger in size, it becomes difficult to crank the drum. In addition, they also become difficult to empty of water unless placed in a sink. Finally, they have not proved popular because they are prone to leaking.
Thus, it is a primary object of the invention to provide a manually operated device for washing clothes and the like.
It is another primary object of the invention to provide a manually operated device for washing clothes and the like that provides agitation action.
It is a further object of the invention to provide a manually operated device for washing clothes and the like that is simple to manufacture.
It is a still further object of the invention to provide a manually operated device for washing clothes and the like that is simple to operate.
SUMMARY OF THE INVENTION
The invention is a manually operated device for washing clothes and the like. In detail, the invention includes a rod shaped handle having first and second ends. A first hollow cone shaped member has a truncated top end attached to the first end of the rod and an open bottom end. This first cone shaped member includes a plurality of holes about its periphery in proximity to the top end thereof, with the plurality of holes having a first total cross-sectional area. An inverted cup shaped member is provided having a closed top end and an open bottom end mounted within the hollow cone shaped member such that the top end is in contact with the interior wall of the hollow cone shaped member forming a first interior chamber. The closed top end includes at least one hole therethrough with a total second cross-sectional area greater than the first cross-sectional area of the plurality of holes in the first hollow cone shaped member.
A second hollow cone shaped member is provided having a truncated first end with a hole therethrough and a second end in contact with and joined to the closed top end of the inverted cup shaped member thus forming a second chamber therebetween. The second hollow cone shaped member has a corrugated surface between the top and bottom ends thereof. The second hollow cone shaped member preferably includes flow passages between the corrugations on the second end thereof in communication with the second chamber. Preferably, a third cone shaped member having a truncated top end is attached to the truncated first end of the first cone shaped member and an open bottom end extending beyond the holes in the first cone shaped member in a spaced relationship thereto.
With a large pot, tub or sink filled with water and dirty washables such as clothes and the like, the device is used in the following manner. The device is grabbed by the second end of the rod and inserted into the water until the first cone shaped member is partially immersed, preferably over a washable item. By pushing the rod down in this manner, water is forced downward through the washables. Simultaneously, water is pushed up through the second hollow cone shaped member and into the second chamber, through the at least one second holes into the first chamber and out the holes in the first cone shaped member. When the rod is pulled upward, a vacuum/suction effect is created, which again sends a rush of water up through the washables. Repeated strokes soon clean the washables.
The novel features which are believed to be characteristic of the invention, both as to its organization and method of operation, together with further objects and advantages thereof, will be better understood from the following description in connection with the accompanying drawings in which the presently preferred embodiment of the invention is illustrated by way of example. It is to be expressly understood, however, that the drawings are for purposes of illustration and description only and are not intended as a definition of the limits of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 1-3
, the device, generally indicated by numeral
10
, includes a first hollow cone shaped member
12
having a flat truncated top end
14
with a short shaft
16
protruding therefrom and an open bottom end
18
. A wall
20
partitions off the interior of the cone shaped member
12
at the top end
14
. Just below the wall
20
are a plurality of holes
22
spaced from each other about the periphery thereof, having a combined first total cross-sectional area. A round rod
23
having first and second ends
24
and
26
, respectively, includes a recess
28
in the first end, which engages the short shaft
16
and is held thereto by friction. The length of the rod
23
should be between 18 to 24 inches in length to insure that the device
10
can be properly griped when in use (to be subsequently discussed).
Mounted within the first cone shaped member
12
is an inverted cup shaped member
30
having a center portion
32
and a side wall
34
. The center portion
32
is joined to the inner wall
35
of the cone shaped member
12
forming a chamber
37
between the side center portion
32
of the cup shaped member
30
and the cone shaped member
12
. The side wall
34
of the cup shaped member
30
extends downward but remains within the interior of the cone shaped member
12
. The center portion
32
of the inverted cup shaped member
30
includes a hole
38
that has a second cross-sectional area greater than the combined first cross-sectional area of holes
22
in the cone shaped member
12
.
Mounted within the inverted cup shaped member
30
is second cone shaped member
40
having a first truncated end
42
with a hole
44
therein and an open second end
46
, and a corrugated type outer surface
48
therebetween. The second cone shaped member
40
is joined to the inverted cup shaped member
30
at the junction of the center portion
32
and side wall
34
thereof forming a second chamber
49
. As illustrated, the corrugated surface
48
produces flow channels
50
between the open end
46
and center portion
32
of the inverted cup shaped member
30
. Of course, the second cone shaped member
40
could be non-corrugated and have notches at the second end
46
to provide flow channels (not illustrated).
A third cone shaped member
52
includes a truncated first end
54
with a hole
56
fitted over the shaft
16
. This is accomplished prior to the rod
23
being frictionally attached to the shaft
16
. The open second
58
extends downward over the first cone shaped member
12
spaced therefrom and terminates beyond the holes
22
.
Referring particularly to
FIGS. 4 and 5
, the device
10
is grabbed by the rod
23
and inserted into the water
64
until the first cone shaped member
12
is partially immersed, preferably over a washable
62
. By pushing the rod
23
down, water is forced downward through the washables. Simultaneously, water is pushed up through the second cone shaped member
40
and into the chamber
49
, through the hole
38
into the chamber
37
and out the holes
22
in the first cone shaped member
12
. The third cone shaped member
52
directs the water downward back into the container
60
. When the rod
23
is pulled upward, a suction effect is created within the chamber
37
pulling air through holes
22
and the water exits the device
10
through the hole
44
again flowing through the washable
62
in an upward direction. Repeated strokes soon clean the washables. The improved performance is due in part because of the flow area of the holes
22
in the first cone shaped member
12
being less than the flow area of hole
38
in the center portion
32
. Because of the constant exposure to water, it is best that the device be completely made of a plastic material.
While the invention has been described with reference to a particular embodiment, it should be understood that the embodiment is merely illustrative as there are numerous variations and modifications, which may be made by those skilled in the art. Thus, the invention is to be construed as being limited only by the spirit and scope of the appended claims.
INDUSTRIAL APPLICABILITY
The invention has applicability to laundry appliance industry.
