DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1-13, the manual clothes washing apparatus of the present invention is shown generally at 100. As will be more fully described below, the clothes washing apparatus 100 includes a housing 102 and plunge basket 126. The housing 102 has a sidewall 103, a closed lower end 104 and an open upper end 106, defining an internal cavity 108 connected to the open upper end 106. The housing 102 further has a surface defining a mating forming, such as a plunge channel 116, on the sidewall 103. The plunge basket 126 is received through the open upper end 106 and within the cavity 108, and includes a sidewall 1128, a lower perforated surface 130 and an open upper end 132, defining a compartment 134 to receive clothing 162 therein, a perforated lid 136 removably connected to the open upper end 132, and a handle 148 having a gripping portion 152 and a rod 154 extending therefrom, connected to the sidewall 128, and a reciprocal mating formation, such as a channel guide 146, for example, configured and arranged to cooperate with the meting formation on the housing 102 to guide the plunge basket 126 within the internal cavity 108 of the housing 102.
Referring now to FIGS. 1 and 2, the housing 102 includes a sidewall, a closed lower end 104 and an open upper end 106 defining an internal cavity 108 connected to the open upper end 106. Although the housing 102 as shown generally has a cylindrical shape, any tubular configuration may be used. The open upper end 106 includes a rim 110 with a depending skirt 112. The skirt 110 and rim 112 may be reinforced with a number of ribs 114, best seen in FIGS. 2 and 3, connected to the housing 102 to strengthen and provide rigidity to the rim 110 and skirt 112 and open upper end 106, generally. The sidewall 103 includes a mating formation such as a pair of elongate, plunge channels 116, depending through the rim 110 and forming a pair of keyways in the internal cavity 108 of housing 102. The plunge channels 116 may be opposed from one another. The plunge channels 116 may extend about midway a length of the housing 102.
A number of bottom projections 118 may extend from the closed bottom end 104 to stabilize and support the housing 102. The bottom projections 118 may include rubberized or otherwise no-slip pads 120 to prevent the housing 102 from sliding or slipping on a surface.
A drain 122 may be located near or on the closed bottom end 104 of the housing 102, as desired, and connected to the cavity 108. A drain valve 124 for selectively sealing the drain 122 is connected to the drain 122. The drain valve 124 may be closed, as shown in FIG. 2, or open, as shown in FIG. 3.
Referring to FIGS. 4-6, the plunge basket 126 includes a sidewall 128, a lower perforated surface 130 and an open upper end 132, defining a compartment 134 to receive clothing 162 therein. The plunge basket 126 is sized and dimensioned to be received within the cavity 108 of the housing 102. A removable perforated lid 136 is configured to secure to the open upper end 132 of the plunge basket 126. The open upper end 132 includes an annular lip 138 extending partially around the open upper end 132. The annular lip 138 includes a surface forming a recess 140 in the annular lip 138. The perforated lid 136 includes resilient members 142 depending from a bottom surface of the perforated lid 136, configured and arranged to cooperate with the recess 140 in annular lip 136, best seen in FIG. 6, to removably secure the perforated lid 136 thereto. Although there are a pair of recesses 136 and resilient members 142 shown in the exemplary embodiment, the number may be selected as desired. The perforated lid 136 further includes a number of fins 144 extending therefrom, providing a gripping surface for a user to lock and unlock the perforated lid 136 to the open upper end 132 of the plunge basket 126.
On the sidewall 128 of the plunge basket 126 are reciprocal mating formations configured to engage the mating formations on the housing 102, such as channel guides 146 extending outwardly from the sidewall 126. In this exemplary embodiment, the channel guides 146 are sized and dimensioned to freely slide within the plunge channels 116 of the housing 102. In this exemplary embodiment, the channel guides 146 also serve as a mounting point for a handle 148, as shown in FIGS. 7-9. More specifically, each channel guide 146 includes a surface defining an aperture 150 therethrough. The handle 148 includes a gripping portion 152 for a user to hold and two elongate rods 154 depending from opposing ends of the gripping portion 152. Each rod 154 includes a distal end 156 with a pair of resilient locking members 158 thereon, best seen in FIG. 7. The distal ends 156 are inserted into the apertures 150 on the channel guides 146, deflecting the resilient locking members 158 until the resilient locking members 158 snap into a locking position when the distal ends 156 of rods 154 are fully seated in each aperture 150 of the channel guides 146, best seen in FIG. 9.
It is important to note that the exemplary mating formation and reciprocal mating formation discussed in this embodiment of the washing apparatus 100, namely the plunge channels 116 and channel guides 146, may be inverted, reversed, or swapped. Regardless of form, the essential feature of the mating formation and reciprocal mating formation is that the two structure cooperate together to guide the plunge basket 126 within the housing 102 of the washing apparatus 100.
In use, as shown in FIGS. 10-13, the housing 102 is filled with water 160 at a desired temperature to a desired height within the housing 102 with the drain valve 124 closed. The appropriate amount of detergent 164 and any other additives is added, as desired. Clothes 162 are placed inside the clothing plunge basket 126, as best seen in FIG. 10, and the perforated lid 136 secured thereto, best seen in FIG. 11. The plunge basket 126 and clothes therein are immersed in the water of the housing 102 and the plunge basket 126 is pulled and pushed up and down thereby agitating the clothing and detergent as illustrated in FIGS. 12 and 13. The clothing is cleaned by the significant water pressure and flow, which is generated inside the housing 102. Superior washing results are achieved with the washing apparatus 100.
After washing is complete, the clothes are preferably wrung out. For example, a roller or lever mechanism (not shown) can be incorporated into the basket 126 to compress the clothes to remove excess water. Such a construction can be similar, for example, to a commercial style mop bucket. Wringing can be carried out over a sink or over or in the housing before or after the dirty water therein in emptied therefrom.
When washing and wringing is complete, the drain valve 124, as best seen in FIGS. 2 and 3, is opened and the dirty water is permitted to exit through the drain 122 in a bathtub or shower stall, for example. Further manual cycles, such as for rinsing, may be carried out, if desired.
The washing apparatus 100 can be made out of any suitable material. For example, plastic is preferably used but any other materials, such as metals, can be used.
It would be appreciated by those skilled in the art that various changes and modifications can be made to the illustrated embodiments without departing from the spirit of the present invention. All such modifications and changes are intended to be covered by the appended claims.
