CLEANING DEVICE WITH INTERCHANGEABLE HEAD BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to cleaning devices of the type having interchangeable heads.

SUMMARY OF THE INVENTION The present invention is directed to an interchangeable head cleaning device in which the handle and the interchangeable pad are secured by the same resilient member.

The primary object of the invention is to provide a cleaning device having an interchangeable head in which the head is secured to the handle by the same member which secures the pad to the head.

Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the invention;

FIG. 2 is an enlarged fragmentary transverse cross section taken along the line 22 of FIG. 1, looking in the direction of the arrows;

FIG. 3 is an end elevation of the plate removed from the handle with no pad attached;

FIG. 4 is a perspective view of the resilient pad and handle securing member;

FIG. 5 is a perspective view of the pad detached from the plate; and

FIG. 6 is a perspective view of a resilient pad used with a modified form of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures the reference numeral 10 indicates generally a cleaning device constructed in accordance with the invention.

The cleaning device 10 includes an elongate handle 11 having a shank 12 extending axially of the lower end thereof and including a generally cylindrical right-angularly extending integral bar 13 on its lower end.

A generally rectangular flat plate 14 is provided with semicylindrical integral rims 15 on opposite side edges thereof. The rims 15 open toward each other forming semicylindrical recesses 16 completely along the opposite side edges of the plate 14. A cylindrical sleeve 17 is positioned intermediate the rims 15 with its axis parallel to the rims 15. The sleeve 17 is rigidly secured to the plate 14 by welding 18 or the like.

A retainer wire 19 includes a pair of oppositely disposed spaced apart parallel legs 20 connected by a generally V- shaped central portion 21. The V-shaped central portion 21 has an upstanding semicylindrical bight 22 formed at its apex. The wire retainer 19 is formed of resilient spring wire so that the legs 20 are normally urged outwardly away from each other with the retainer positioned against the plate 14 with the legs 20 engaging in the recesses 16 ofthe rims l5.

A generally rectangular cloth cleaning pad 23 is adapted for use with the plate 14 with the side edges 24 thereof engaged in the recesses 16. The legs 20 engage the side edges 24 to retain the pad 23 in contact with the plate 14.

The bar 13 engages in the sleeve 17 to mount the plate 14 to the handle 1 l for pivotal movement about the bar 13. The bight 22 of the retainer wire 19 is positioned adjacent one end of the sleeve 17 to hold the shank 12 to thus prevent the bar 13 from being slid out of the sleeve 17 until the retainer wire 19 is removed.

In FIG. 6 a modification of the invention of FIG. I is illustrated as an attachment for the FIG. 1 device. A generally rectangular resilient block 25 has a flat upper surface 26 and a flat lower surface 27. The lower surface 27 has upwardly and outwardly tapering side portions 28. In the use of the cleaning device 10 for certain types of cleaning and polishing it is desirable that the pad 23 be replaced with the pad 25. The pad 25 is resilient and can be used for scrubbing or polishing directly or may have a sanding sheet, polishing sheet or other material secured to its lower face.

The tapered side portions 28 of the pad 25, when attaching to the plate 14, engage in the recesses 16 and are held therein by the legs 20 of the retainer wire 19.

Having thus described the preferred embodiments of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.

What is claimed is:

1. A cleaning device comprising a flat plate with opposite side edges upturned inwardly as rims extending toward each other and forming longitudinal recesses facing each other, said plate having a sleeve secured to its upper surface, a flat flexible piece of material mounted on said flat plate and having its side edges extending into said recesses, resilient holding means engaging the material in said recesses releasably securing said flexible piece of material to said plate, handle means including a shank with a right angle cylindrical bar extending into said sleeve pivotally connecting said handle means to said flat plate, resilient means in alignment with said sleeve and spaced therefrom to prevent said bar of said handle means from inadvertently coming out of said sleeve, said resilient holding means including a spring wire having a pair of oppositely disposed spaced parallel legs integrally connected by a V-shaped member, with said resilient means comprising a semicylindrical upstanding bight integrally formed at the apex of said V-shaped member.

2. A device as claimed in claim 1 wherein said oppositely disposed legs engage against the opposite side edges of said material in said recesses securing said material in said recesses.

3. A device as claimed in claim 2 wherein said sleeve has its axis extending parallel to said rims and is positioned substantially midway between said rims.

4. A device as claimed in claim 1, wherein said rims on said flat plate are semicylindrical in form.

5. A device as claimed in claim 1, wherein said sleeve has its axis extending parallel to said rims and is positioned substantially midway between said rims.
