DUST REMOVER FOR REMOVING DUST, HAIR OR OTHER LOOSE
PARTICLES FROM OBJECTS SUCH AS CLOTHES, TEXTILES7 FURNITURE ETC

The present invention relates to a dust remover for removing dust, hair or other loose particles from the surface of objects such as clothes, textiles, furniture etc, comprising a substantially cylindrical roller which is rotatably supported on a holder, the peripheral surface of said roller being provided with an adhesive layer for removing said dust par~icles etc by adhesion when the roller is brought into rol-ling contact with the surface of the object to be cleaned.
lS Dust removers of the kind mentioned are pre-viously known and referred to on the market as "clothe-care rollers, dust rollers" etc. Such dust removers which provide an efficient means for its in-tended purpose, include a substantially cylindrical roller mounted on a holder, said roller having wound thereon in a number of layers a strip of paper which on its outwardly facing surface is coated with a non-drying, highly adhesive substance. When brought into roll~ng contact with an object to be cleaned, e.g. an article of clothing, dust particles, hair etc on the surface of the obJect will get stuck on the adhesive layer of the roller, thus providing a most e~ficieng cleaning of the ob~ect. When not ~n use, the adhes~ve sùrface must be protected in order not to become satura~ed w~th dust particles and also to avoid unintentlonal adhesion to objects in ~he vicin-ity of the roller. In the most common dust removers of this kind available on the market, this usually is achleved by wrapping a protective glossy piece of paper or film around the roller sùrface or by passing ,:' ... . _ _.. . _ _. _ _ ... ._ . _ .. .. . . ._ ... _ .. .. .. . . .

66;2 a protective ~ubular cover over khe roller from the end thereof. A disadvantage in using a glossy piece of paper to protect the adhesive layer of the roller ~s that said piece of cnvering paper must be removed from the roller before using it for cleaning purpose, and must be stored and then rewrapped around the rol-ler when the used part of the adhesive pap~r has been torn away. When removing the protect~ve paper it runs a risk of being damaged, as is also the case during storage, particularly if it is stored in a pocket or the like. Even if the use of a separate, tubular pro-tective cover to be passed over the roller involves a more simple procedure, a remaining disadvantage is that during the use of the roller for cleaning pur-pose the tubular cover mus~ be stored in a sui~ableway and be reintroduced on the roller when the clean-ing operatfon has been finished and the used adhes~ve paper strip has been torn o~f. Still another disad-vantage of the tubular cover that it must be passe~
over the roller from one end thereof, wh~ch means that it cannot be used for such dust removers wherein the roller is mounted between the legs of a fork-like holder. A further disadvantage is that it easily ad-heres to the roller surface, which makes it more dif-ficult or even ~mposslble to remove the cover whenthe roller shall be used~
According to another previously known type of dust removers the cylindrical dust roller is enclosed within a protective casing compris~ng one tray-llke part having two end walls ~n which ~he roller ls ro-tatably supported and a cover divided into two sepa-rate pieces, each one be1ng sw1ngably connected to the tray-like member by means of a pair of links, ~or swinging said cover pieces in opposite directlons in the longitudinal direction of the rol1er between a : .

%

position above the tray-like member, thereby enclos-ing said roller, and a pos~tion undernea~h the tray--like member, protruding perpendicularly therefro~
thereby forming a handle for holding the dust remover S during use thereof.
According to another known dust remover of a similar type, the cover is made in one piece having a tray-like conf1guration, one end of said cover being swingably connected to the ~ray-like member support-ing said roller, for sw~nging movement between a po-sition in which the two tray-like members together form an enclosure for the roller, and a position ln which the cover is swung 180~ longitudinally with respect to the roller and in th~s position forming an axially protruding handle.
Being advanta~eous in tha~ the protective cover for the roller does not have to be removed and stored somewhere during use of the roller for cleaning pur-pose, the dust removers described above are of a rather complicated design including, in the first case mentioned, a tray-like holder for the roller, two separate cover-pleces, two pairs of links havlng one end plvotally connected to a cover p~ece and the opposite end plvotally connected to the holder, and in the second case a tray-like holder for the roller, a tray-like ~over, one end of which being piYo~ally connected to one end of the holder and being provided with means for keep~ng the cover fixed ei~her in a closed posit10n 0nclosing the roller or in a fully open position form~ng a h~ndle. Th~s results in d~f-ficulties as well as respect to manufacture and as-sembly of the dust remover as w~th respec~ to the use thereof for ~ts purpose.
One ob~ect of the present inYention is to pro-vide a dust remover of the kind m0nt~0ned in1tially:' 6~

and referred to above, which does not involve the disadvan~ages discussed~above although:including a cover permanently attached to the holder of ~he rol-ler, said~cover being ea's1ly adjustable into a posi-tion in which the roller may be brought into contactwlth an ob~ect to be cleaned~ and which In simple manner may be brought into a posi~ion for protecting the adhes~ve layer of the roller when the cleaning oper,a~ion~has been finished. ::
: lO -~ Another ob~iect of~:the lnvent10n i;s to proved~`a : dus~ remover having a simple design which may be ma-nufactured and assembled without difficulties and whlch is easy to use.

The dust remover illustrated in:the~drawi:ngs` ~ :
compr~is~e~s~ a~cyl~ndrical rol~ler~1;.cons.ist,~ng,of.-a,tu~
bular core 2'which by means of`radially exténding flanges 3 is connected with~a hub 4, each end of which being provided with an ax~ally protrudin3 stub shaft 5. On the peripheral surface of the tubular core 2 are wound a number~of layers 6 of a:paper strip coa~ed on its outwardly~fdc;i;ng:surface:~w~th a ~:

. 1 thus is provided with an adhesive~peripheral outer surface tG which dust part~cles9 hair etc adhere when the rol7er 1 is brought into rolling contact with an object fouled with such particles e.g. clothes, tex-tiles etc.
The roller 1 is supported by a holder compr:~s~ng a primary casing par~ 7 in the :form of a tray-like, substan~ally half cylindrica1 member 9,-:sai~d~cas~ng being provlded at iks ends w~th'~e'nd~walls'8~ The:'st~b sh~afts :5 protrud~ng axlally~,from thé~roilèr~s~l arè`:
mounted ~n grooves or slots prov~dëd;ln sa'~d''end~
walls 8, sald grooves or slots~preferably~b~e~ng~de-s~gned so that the stub shaf~s 5 w~ll sllde ~nto a locked posltlon within sald grooves or slots due to a small pressure force exerted on the roller 1 ~n khe d~rect~on towards the bottom of sa~d grooves or slots. The grooves or slots are' designed so as to provide a resllient lock~ng funct~on for block~ng ~he 76~2 falling out from the casing part 7 when the roller is used. In the embodiment shown in FIG 1 - 49 said end walls protrude in the rad~al direction beyond the outer surface of the half cyl~ndr~cal tray-like mem-S ber 99 ~he surfaces o~ safd protruding port~ons of the end walls 8 facing each other being prov~ded with half circular grooves 10 forming guide grooves for a second casing part 11 which may be slidably displaced within said grooves for rotational movement with respect to said prlmary casing part 7.
The sec~ndary casing part 11 comprises a sub-stantially half cylindr~cal shell having a width sub-stantially corresponding to the distance between the grooves 10 in said end walls 8, except for a certain clearanceO As mentioned, the secondary casing part 11 is displaceable in the guiding arrangement formed by the grooves 10 and may by turn~ng it around-.~the cy~
.lindrical shell 9 of the primary casing part 7 be brought into the position shown in FIG 3 enclosing the peripheral surface of the roller, or into the po-sition shown in FIG 4, completely displaced into the grooves 10 enabling a part of the cylindrical, peri pheral surface of the roller 1 to be brought lnto rolling contac~ wlth the surface of an objec~ e.g. an art~cles of clothe, to be cleaned from dust, hair or other loose partlcles. The perfpheral length of the secondary casing part 11 should be long enough for mak~ng 1~s edges 12 extend a certafn distance into the grooves 10 when sald secondary casing par~ or co-30 ver 11 ~s in the clos~ng positfon ~ndica~ed in FIG 3.The peripheral length should also be long enough to allow the edges 1~ of the secondary cover 11 to pro-trude a certain d~stance from the prfmary casfng part 7 when said secondary casfng part or cover 11 ~s ful-ly d~splaced into the grooves as ~ndicated in FIG 4.

1:~876G2 The longitudinal edges 12 should preferably be shar-pened for facilitating ~earing off a paper strip which has been clogged with dust particles. Al~erna-tively, it is possible to having the edges of the S prlmary cas~ng part 7 sharpened ~nstead of the edges of the secondary casing part 11, or to sharpen the edges of both casing parts 7 and 11. The primary and secondary casîng parts 7, 11 may preferably be locked with respect to each other in the open pos~tion shown in FIG 3 and ~n the closed position shown ~n FIG $ by means of locking means of the snap-action type ar-ranged between said casing parts. FIG 5 illustrates an alternative guiding arrangement for the rotational movement between the primary and secondary casing parts 7, 11. In ~his arrangement the end walls 8 ex-tend in the radial direction only to the inside sur-face of the half cylindr;cal shell 9 of the primary casing part 7. Instead said shell 9 protrudes beyond the end walls 8 forming guiding edges 13 cooperating with corresponding guide grooves 14 at the ends of the secondary casing part 11.
The primary casing part 7 is preferably rigidly connected with a handle protruding in the ax~al di-rection of the roller as indicated in FIG 1 - 7.
According to an embodlment not illustrated in ~he drawings, the handle may have ~the form of an U-shaped gable having two parallel protrud~ng branches, the free ends of wh~ h being rlgidly connected w~h the end walls 8, the opposite ends of said branches be~ng ~nterconnected by a bar etc from wh~ch the handle ex-tends perpendicularly with respect to the roller.
FIG 6 and 7 ~llustrate a further embod~ment accord~ng to the present invent~on. In th~s embodi ments also the secondary cas~ng part 11 has the form 3S of a substant~ally half cylindr~cal shell prov~ded ~ ~3766;~

w~th end walls 8' at the ends thereof. The internal dimensions o~ the secondary casing part 11 are so much larger than the outside ~imensions of the prima-ry casing part 7 that a small gap is formed, thus providing a clearance between the casing part 7 and the casing part 11 enabling relative rotational move-ment without interference. In the embodiment illust rated in FIGs 6 and 7 the relative rotàtional move-ment is not obtained by means of circular guiding grooves as in the embodiments previously described.
Instead the secondary casing part 11 is rotatably supported at one side by the stub shaft 5 protruding through end wall B of the priimary casing part 7, or by the outer surface of an angular collar surrounding sald stub shaf~ 5 on the outside end of wall 8. At the other end the secondary casing part 11 is rota-~ably supported on the handle 15 protruding axially from the corresponding end of the primary casing part 7. For this purpose the secondary casing part 11 is provided with a partly tubular attachment means act-ing as a kind of bushing having a C-like cross sec-tion with a gap slightly smaller than the outer dia-meter of the corresponding part of said handle 159 for enabling attachment there~o by pressing it over the handle in the transversal direction thereof, ~hus providlng a ro~ational suppor~ for the secondary cas-ing part 11 on said handle 15. The embodlment accord-ing to FIGs 6 and 7 correspond ~n other respects wlth the embodimen~ previously described and w~ll thus not be descr~bed in further detail with reference to FIGs 6 and 7. The dust remover illustrated in FIGs 6 and 7 is advantageous from manufacturing point of view, and due to this it represents the preferred embodiment of the invent~on.
The invent10n is not limited to the embodiments 76~2 described above but may be subiect ot variations within the scope of the appended claims.
