6 Summary of the Invention 8 The novel construction of the present invention provides 9 several advantages over the prior crevice tool constructions.
10 Applicant'~ multi-purpose tool is adapted for use both as a 11 crevice tool in the conventional manner, and as a tool for 12 cleaning between relatively inaccessible surfaces, such as between :
the slats of a venetian blind. Conversion of the tool from one 14 use to the other is accomplished merely by advancing or retracting 15 a sliding panel forming part of the device. No addition or 16 removal of brushes is required while effecting such conversion~
17 Thus, the tool of the present invention is self contained and 18 re~uires no separate parts or pieces.
19 ~hen operating to clean venetian blinds and the like, 20 withdrawal of the slidin~ panel uncovers an elongated opening~
21 Because the opening i9 of larger area than the end opening of the 22 tool, and because of the tapering shape of the tool becoming more 23 and more flattened toward the end port, thus reducing the 24 effective cross sectional area of the duct, air will be drawn in 25 through the elongated opening~
26 Strip brushes of low height are arrayed along both sides 27 of the elongated opening and serve to disloage dust, etc. from 28 venetian blind slats and the like. These brushes are particularly 29 suited for cleaning venetian blinds and are composed of a mixture 30 of nylon and boar's hair bristles. The described arrangement of 31 the strip brushes on both sides of elongated opening increases ~ 9~5~
1 surface cleaning space over existing devices, resulting in a much 2 more effective cleaning action. Instant conversion back to 3 crevice cleaning mode is readily accomplished by merely sliding 4 the panel to its covering position.
It is therefor~ an object of the present invention to 6 provide an attachment tool for a vacuum cleaner hose which 7 provides the advantages of both a crevice cleaniny tool and a 8 greatly improved tool for cleaning between venetian blind slats ir 9 a single unitary device.
Another object of the present invention is to provide a 11 attachment tool of the character described which is readily and 12 instantly convertible from crevice tool mode to venetian blind 13 mode without requiring attachment or detachment of parts.
14 A further object of the present invention is to provide an attachment tool of the character set forth which may be 16 operated with facility in either mode, which is simple and sturdy 17 in construction, and which provides for ready replacement of the 18 strip brushes, when worn.
19 A still further object of the present invention is to provide a multi-purpose attachment tool of the character describe~
21 which is useful for accomplishing easier and more efficient dust 22 removal from the tops of books in bookshelves and similar areas o 23 limited insertion space.
24 For a fuller understanding of the nature, and further objects and features of advantage of the present invention, 26 reference should be had to the following detailed description, 27 taking in connection with the accompanying drawings and the 2 appended claims.

17 ¦ Description of the Preferred Embodiments 1~ l 19 ¦ Referring now to the drawings in detail, it will be seen 20 ¦that the attachment tool for a vacuum cleaner hose o~ the present 21 ¦invention basically includes an elongated flattened tubular 22 Ihousing 11 having an end 12 adapted for connection to a vacuum 23 ¦cleaner hose 13 and an opposite end 14 providing a flattened air 24 intake opening 16, one flattened face 17 of said housing being 2~ formed to provide a single elon~ated opening 18 therethrough 26 extending centrally of the face 17 adjacent to the end 14, 27 together with means 19 on the housing 11 formed for selectively 28 overing opening 18 for admitting air therethrough to the interior 2q 21 o~ the hou~ing, and a pair of elongated strip brushes 22 and 23 30 carried on the flattened face 17 of the housing 11 and extending 31 along opposite side of the elongated opening 18.
~iLt~3~5~
1 ¦ As may best be seen in Figure 3 of the drawings, the 21 housing 11 tapers as it flattens out to become thinner approaching 3¦ end 14 whereby the cross-sectional area of the interior 21 of the 41 housing diminishes along its lenyth toward end 14. The tapering 51 f the housing 11, as illustrated in the drawings, provides the 6¦ flattened face 17 in which the opening 18 is formed. The means 19 71 for selectively covering the opening 18 here consists of a 81 ~lattened, elongated rectangular panel mounted on the housing 11 for endwise movement between a closed position fully covering ~he la¦ elongated opening 18 and an open position uncovering the elongatea 11 opening, the sliding panel 19 being shown in an intermediate, 12 ¦partially opened position in the drawings~
13 ¦ As here shown, the housing 11 is formed with confronting 14¦ grooves 24 and 26 running along the longer opposite sides 27 and 15 ¦28 of opening 18, the longer side edges of the panel 19 being 16 ¦slidably mounted in the grooves 24 and 26. An upwardly extending ~71 tab 29 is farmed on the upper side of panel 19 for manual 18 engagement to facilitate sliding of the panel between its open and 19 closed positions.
201 Preferably, as here shown, the housing 11 and sliding 21¦ panel 19 are of molded plastic and the elongated strip brushes 22 22 and 23 are mounted in slots 31 and 32 formed in housing 11 along 23 ¦ the opposite longer sides ~7 and 28 of the opening la, outboard of 24 ¦the grooves 24 and 26, see Figure 4. The strip brushes extend 2~ ¦ slightly beyond the ends of the elongated opening 18 and 26¦ perferably are curved inwardly toward each other at the ends of 27 ¦ the brushes adjacent to housing end 14, see Figure 2.
28 The described configuration markedly facilitates the 29 ¦ cleaning action of the tool when used between closely set surfaces 30 ¦ such as slats of venetian blinds, between the tops of books and 31¦ the shelf above, between and behind air conditioning and 11'79"L~8 1 ¦ refrigeration units along side walls, between the slats of window 2 ¦ shutters, louvers and between the glass strips of jalousie 3 ¦ windows, etc. The multi-purpose tool of the present invention is 4 ¦ extremely versatile with regard to the places which may be cleane 51 and the adaptability of the tool to various modes of cleaning.
6 I The tool may be readily converted to crevice cleaning mode merely 7 I by sliding panel 19 to close opening 18, and may be readily 81 converted to its mode for cleaning between closely spaced surface 91 by merely sliding panel 19 to open position.
10 ¦ In accordance with the present invention, the strip 11 ¦ brushes 23 have short, fixed bristles provided in a combination o 12 ¦ mixture of natural boar's hair and nylon. The combination ~f 13 ¦ boar's hair and nylon increases both the flexability and 14 ¦ durability of the brushes. The flexability of the boar's hair 15 ¦ bristles allows and for relatively delicate cleaning and the 16 ¦ stiffness of the nylon bristles, together with the low height of 17 ¦ the bristles, provides sturdiness in cleaning calced-on dlrt. ~he 18 ¦ location of the bristles closer to the end 14 of the tool provide 19 ¦ an increase in the cleaning area for more effective dis~urbing anc 20 ¦ removal of dust particles. The location of the brush bristles 21 ¦ alon~ the sides of the opening 18 directs the air flow in an 22 ¦ efficient manner not found in prior crevice tools.
23 ¦ As here shown, the strip brushes 22 and 23 have rows o 24 ¦ bristles of the type described held in brush form by metal backinc 25 I strips or clips 33 and 34, with these clips bein~ insertable into 26 ¦ the grooves 31 and 32. Perferably, the grooves 31 and 32 are 27 formed to retain the clips 33 and 34 in place by the spring 28 I pressure afforded by the metal of the clips, thus permitting easy 29 ¦ removal and replacement of the brushes when worn. For the best 30 ¦ accomplishment of the purposes of the tool the bristles should 31 I project about one ~uarter inch from the housing~ and the housing i79'~5~3 ~
1 should be about one and three sixteen inches wide by about three 2 eighths ;nch thick at the end 14.
3 From the foregoing, it will be seen that the attachment 4 tool of the present invention provides a novel and readily convertible multi-purpose tool capable of use both as a crevice 6 tool and as a tool ~or the cleaning between closèly positioned 1 s rfaces su as the slat of venetian blinds, etc.
