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
,:'

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. ::

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

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

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.

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.
