CLEANING DEVICE Filed May l2, 1955 Y MMM INVENTOR. Fokkfsr M HARRIS United States Patent lll ICLEANING DEVICE Forrest `-W.I1Iari'is, Los-Angeles, Calif.
Application May 12, 1953,` Serial No. .354,505
'-9-Claims. (Cl. 15-210) This invention relates to a cleaning device which may be utilizedfor various types of cleaning operations,the cleaning device 'being composed'of two independent sections which whenused as ran assembly are particularly suitable for cleaning slats, such as Venetian .blind slats, and when used independently, arey particularly suitable for cleaning flat surface areas, .such as Windows, windshields and thelike.
The independent sections may be readily -assembled together for Slat cleaning purposes and may bejrust ,as easily disassembled foruse as independent cleaning devices.
An important object ,of .thevinventionis vto provide a cleaning device with a hinge structure `of a type which makes it possible to form each `of thesections of a molded synthetic resin. t
A further object of-the invention is toyprovide a cleaning device comprised of two independent sections which when used as an assembly are suitablefor certain types of `cleaning operations, .said sections being readily separable-for useindependentlyin other types ,of cleaning operations.
A further object of the invention .is to provide-'one .of
`the sections Witha replaceable squeegee whichlisanchored in a novelmanner, to one facethereof.
A further ,object of vtheinvention is toprovidea novel hinge structuresuitable for use witha pairlofarms wherein itis desired to separate said armson frequent occasions.
A further object of :thednventionsto providea cleaningdevice whichis relatively inexpensive to'v manufacture.
Other objects andadvantages `will be apparent .upon-ei@ .amination-of the following specification and appended Aoppositefaces of. the Vhan'clleportions andthe .oppositeend o'f thehinge structure exposed.
The invention contemplates theuse of .twoindependent `sections generally .designated .by the .lettersAand B. The sectionA includes `a `handleportion 2 `a head ,3.-and a ,socket 4` formed .at thefree .end ofthe yhandle portionall of which are-moldedintegrally .froma material such-as a syntheticresin. The socket portion is 4bifurcated thereby .providingopposed recessed bearing plates 5and.6. `Each bearing 4plate .is bordered .on three .of .its edges with an inwardly projecting continuons hange, the flange portions 7 andS being slightly divergentrelativeto each other commencing from the base'flange 9, thereby forming an enlarged entrance mouth to facilitate initial entry of the "free end .of'section B during theassembly operation. The 'sideanges'fl and "8 servegpr'imarily to ,guide the-pintle portions 110,!forme'd on'thetongue `11 during the descent l'ofvsarneltowardsthe:bottom of thewsocket 4, thelower Aregions'of said side I"flanges, however, additionally function ltolirnit `the lfore and aftfmovement-of'the pintle por- Aice 'tions 10 after the tongue is fully inserted intothe 'socket `(asbest viewed in Fig. l),v it being apparent'that the leading edges 12 ofthe pintle'portions 10 will engage walls 8 Iand Vthetrailing Vedges 13 will engage walls 7 whenever on'eattempts to move section B rectilinearly relative to' section A after said sections are fully assembled together as viewed in Figs. l and 2. The function of the base flanges 9 will be set forth hereinafter.
The section B includes a handle portion 14, a head 15 andthe tongue portion 11, previously mentioned,'all of Which'are molded integrally from a material such as a synthetic resin. The longitudinal edges 'on 'the opposite sides of the handle portion 11 are notched at 16-and 17, said notches being equidistant from the free end 18'0f the tongue and each notch deninga gapbetween` the leading edges 12 and the terminal portions 19 of the handle which gap is ample to accommodate the Wall thickness of the 'flanges 7, 8 and 9 (as best Viewed in Fig. l) during the assembly operation. It will be noted that there will be a slight amount of longitudinal play between the two sections due 'to the size of these notches, however, this clearance factor is instrumental in assuring rapid assembly and disassembly of the two sections and the resultant longitudinal play is of no consequence when the assembled sections are in use as a cleaning device. The
`pintle portions 10 are formed integral with ,the tongue and include one on each side thereof. Each pintle portion resembles asegment of a cylindric with the upper surlfaces 20 vhaving the curved contour andthe underneath surfaces being flat. lt `will'be noted that the'pintle portions lll overhang 'the fianges 7,8 and 9 and can only be 'Withdrawnfrom socket 4 Via the mouth 21 thereof.
ln theassembly of the twosections the'handle .portions 2 and `14 are first positioned in aligned end to end fashion (as viewed in Figs. 4 and 5) with the pintle portions of thetongue manipulated directly over themouth of socket '4. Thenrthe tongue 11 is lowered into the socket, notches v1'6 .and 17 accommodating "flanges 7. When the curved ,Surfaces 20 of the;pintle portions engage their respective baseilanges y), then the`handle14 is swung, approximately when the two sections are hinged together in fully closed position. The free end of the rubberflike peg has a tapered 'nose'portion 26 which in conjunction with the V-groove 24- .aiords a centering conditionto maintain the opposed arms in a common longitudinal alignment as well as lending support and stahilityto the over-all assembly which is additional to that afforded by thehinge connection. The
pegisanchored within thebore 27 in .boss 28 formed in- `tegral with section A, said boss also functioning as the bridging portion for the bifurcated socket 4.
it will be ,noted in viewing Fig. l that when the nose 26 of ,the peg is fully inserted within the groove 24 and is in engagement with thesides of the groove, the cleanin g pads 29 and 3ft, which4 are anchored to the-respective inner faces of the head portions ofthe sections A and B, ,are maintained in spaced relation, the 4spacing being -suicient to assure that the opposed cleaning pads may be readily manipulated to embrace'between them the article to he cleaned, such as a Venetian blind slat 31. The resistanceoffered by theppeg 25 is 4easily overcome when the handle portions `of the assembleddevice yare manually 'grasped in one hand and squeezed toward each other,
lby application of `manual pressure, the rubber-like peg `beingcompressed slightly and possibly deflected slightly due-to itslfexible characteristics. The cleaning pad 29 thus engages one face of slat 31 and pad 30 the opposite face of the slat, the cleaning operation then being consummated by simply drawing the closed pads along the length of the slat. When one slat is cleaned, the manual squeezing pressure is released and the rubberlike peg functions in the manner of a spring to automatically separate the cleaning pads to the condition indicated in Fig. l and the device is ready for transfer to a second slat. When the manual pressure on the handles is released and the cleaning pads are separated slightly, the leading edges 12 of the pintle portions are resting on the flanges 9 with the trailing edges 13 slightly raised from the flanges. When the handles are squeezed together, the iat under surfaces of the pintles approach a condition of full face to face engagement with the ilanges 9.
The cleaning pads may be of sponge rubber, lambs wool, felt, fabric or other suitable material, Fig. l disclosing a sponge rubber type of material.
Section B may be readily separated from section A by simply swinging the two arms approximately 180 degrees about the axis of the hinge pintles in the reverse direction from that hereinbefore described relative to the assembly of the device until the sections are in end to end alignment as viewed in Figs. 4 and 5 after which the tongue of section B is simply withdrawn out of socket 4 in an upwardly direction when viewing Fig. 5. Either of said sections may then be utilized to clean at objects such as windows, the cleaning pads, of course being applied directly to the window surface. ln this type of cleaning operation section B is provided with a rubberlike squeegee 34 for scraping the excess water or cleaning uid from the window. The outer face of head portion is provided with a shallow groove 35 which traverses the entire width of the head. A binder strip 36, preferably molded from a synthetic resin, has a groove 37 extending throughout its entire length. The binder strip may be anchored to the head portion 15 by rivets 38 so that the groove 37 is disposed opposite the groove 35 thereby providing an elongated pocket within which the base portion of the squeegee is removably anchored, said base portion being inserted at either end of the pocket and then pushed throughout the length of the pocket until fully inserted as shown in Fig. 2. The base portion of the squeegee is provided with a full length bead 39 which is rather readily compressible being of comparatively thin section and thus assists in aiiording frictional contact with the wall of groove 37 to help prevent lengthwise dislodgment of the squeegee. The scraping blade 40 of the squeegee projects through the elongated mouth formed between the longitudinal marginal edges 41 and 42 of grooves 35 and 37. The front wall 43 of the binder strip merges with the base 44 and the longitudinal juncture of these two walls provides a full length scraping edge 46 which may be used for scraping purposes (preferably but not necessarily with the squeegee removed).
