Referring to the drawings, the reference numeral 10 generally designates the cleaning device of the present invention and is provided with a substantially flat rectangular plate member 12 having its opposite longitudinal sides 14 bent upwardly and inwardly so that the upper in-turned rims 16 face each other, as best seen in FIG. 2. It will be noted that the longitudinal sides 14 are of the same configuration, but disposed in opposite directions, or facing each other.
One of the longtiudinal sides 14 is provided with a slot 18 in the central portion thereof, as best seen in FIG. 1.
The central midportion of the plate member 12 is provided with a sleeve or cylindrical open end tube 20 for receiving a handle 22 therein.
The handle means 22 is provided with a short cylin drical or bar section 24 that is disposed at right angles with the main portion of the handle and this short portion 24 is the portion that extends into the sleeve or tube 20.
The in-turned rims 16 are provided with a plurality of serrations or teeth 26, as best seen in FIG. 5, for gripping a pad or disposable sheet of cleansing or wiping material 28.
The plate member 12 is further provided with a pair of spaced semi-circular wing members 30, which wing members are spaced in alignment with the sleeve 20 and spaced apart therefrom, as best seen in FIG. 1.
The cleaning device is further provided with a biasing member in the form of a spring 32. The wire spring 32 has a in-turned section 34 comprising two legs 36 which converge toward each other and which have a semi-circular ring or loop 38 connecting the inner ends of the legs. The legs 36 have their outer ends bent back so as to form two elongated parallel legs 40. The spring wire member 32, as best seen in FIG. 1, is adapted to have its loop portion 38 disposed over the sleeve 20 and its legs 40 adapted to be disposed within the confines of the sides 14 of the plate member 12 and below the rims 16, as best illustrated in FIG. 2, in order to properly secure a sheet 28 of material to the plate for use in waxing a floor or cleaning a window or for whatever use may be desired in connection with the cleaning device of the present invention. In operation, the handle 22 is first attached to the plate member 12 by pushing the short section 24 between the semi-circular wing members 30, best shown in dotted lines in FIG. 5, so as to spread the wing portions 30 apart. Thereafter the section 24 is inserted all the way through the sleeve 20 and the wing members 30 prevent the handle 22 from becoming inadvertently detached from the plate member 12. Thereafter, the sheet of material, which may be used for a waxing pad or a cleansing pad, and which sheet of material may be made of any desired material, such as a cloth, or a paper material, is then detachably connected to the plate member 12 by inserting its opposite ends under the rims 16 so they are gripped by the teeth 26.
It will be noted that the sheet of material 28 is provided with slits 42 therein which has one of the slits 42 in alignment with the slot 18 when the sheet of material has been attached to the plate member so that the slit 3 42 will coincide with the slot 18 and permit the handle to be easily passed through the slot 18.
After the sheet of material 28 has been disposed in a position with itsopposite edges tucked under the rim 16, the spring member 32 is then positioned over the plate member 12 so that its loop 38 will rest on the outer surface of the sleeve 20 and its resilient legs 40 will be clamped against the opposite edges of the sheet of material 28. and securely hold the sheet of material 28 in its proper position on the plate member 12,as best illustratedinFIG. 2.
Referring to the embodiment. of the invention illustrated in'FIGS. 6 to 10, this modification is substantially the same as that described in connection with the embodiment of the invention illustrated in FIGS. 1 to except that the cleaning device is provided with a different type of holding member 46, instead of thespring biasing holding member 32 in the other embodiment.
In this embodiment of the invention, the holding member '46 comprises a substantially flat resilient plate member with a central semi-circular groove or detent 48 extending the full length of the rectangular plate 46 and the handle sleeve holding member 50 is secured in this groove 48.
In securing a sheet of material 28 to the plate member 12 forming the pad means of this embodiment of the invention, the holding'member 46, after the sheet 28 has been placed or wrapped around the plate member 12, as described in connection with FIG. 1, is pressed against the upper surface of the plate member 12. The plate member 46 is provided with a catch 52 which will go under one of the rims 16 and sides 14 of the plate member 12. To release the plate holding member 46 from the plate member 12, it is only necessary to press the i holding member 46 at the portion 54 which is adjacent the slotted 'portion'56 in the plate 46,'as best seen in FIG. 8.
It will also be noted that this embodiment of the invention 'may be provided with an upstanding squeegee 58,'if desired, which may be suitably secured to the holde ing plate member 46 by any suitable and well known with a large transverse slot 66 which is adjacent a longi- I tudinal narrow slot 68.
This squeegee is attached 'to the plate 12 by sliding the squeegee 60 onto the plate,12 so that the sleeve is positioned within the narrow slot 68.
Thus, this embodiment of the invention provides a W detachable squeegee '60 and the positioning of the squeegee 60 over the sleeve 50 prevents the handle 22 from inadvertently becoming detached. from its'plate member 12 which forms the pad means for attachment of the sheet of material thereto.
Referring to the embodiment of the invention shown 7 in FIGS. ,11 and 12, this is' substantially as that described in connection with FIGS. 1 to 5, except that the plate member 12 has the wing members 30 spacedmuch closer to the sleeve or tube 24. The sleeve or tube 24is provided at its'end adjacent the wings-30 with a slot 72 cut out of the 'end of the sleeve or tube 20. The slot 72 is formed between two upstanding portions 74 of the sleeve 20 l asbest seen in FIG; 12.
It will be noted that this embodiment of the invention is provided with a substantially deep sponge layer of material 76 for cleaning purposes or the like.
When the deep or heavy sponge is utilized on the device, or a deep broom section is used for pushing dirt on streets or the like, this type ofconstruction would pivot or roll unless the structure set forth in FIGS. 11 and 12 is utilized to prevent the handle from pivoting. The structure of the sleeve with the cut-out therein will hold the handle in the correct angle for this type of a heavy padding member under the plate member 12.
Thus, from the foregoing description of the present invention, it is apparent that the cleaning device of the present invention provides a compact and simple structure which has biasing means in the form of a wire spring or a plate means for securely connecting a disposable or removable pad member to the head or the pad means .of a cleaning device.
Inasmuch as various changes may be made in the relative arrangement and location of the parts of the invention, it is not meant to limit the scope of the invention, except by the appended claims.
