BAC~GRO~D cr Ir~ ~ ON
The pre~ent invention relates ~o a rollin~ shutter ~or a cover part of a wall or roof opening, especi~lly for a roof window, provided with a ~urnable blade. More par~icu-larly, it relates to such a rolling shutter which has a rolli~g shutter we~ co~posed of rolling shutter bars or the - like, a rolling ~hutter sha$t for windin~ an un~indin~ the rolling shutter web, two lateral s~ppor~s in whiah ~he rolling ~hu~t~r ~ha~ is ro~atably s~pported, two parallel side bars provided wit~ guides for guiding the rolling shutter web, and 3~pported turnably about an a~is parallel to the rolling ~hutter sh~ft, an upper blind or aovering the rolling ~h~ter web from above, and a rolling ~h~tter actuating deviae.
Rolling shutte~s of the above ment~oned type are known in the art and used in two variants. Th~y serve mainly fo~ ~losing of roo windowx moun~ed in inclined roo~ surfaces and havin~ blind frame~ fixedly mounted in the roof and a windo~ ~lad~ turnable or tilta~le at least ~bout a hori~ontal axis. Such roo~ wind~ws are ~ometimes identi~ied as roof ~esidenae window, roof sura~e window or ~he like.

Moreover, pivot ~ins 1~ of side parts 14 are turnabl~ ~upported in ~he supports 6. They are arranged parallel to one ano~her at a di~ance corre~ponding to the ~istance between the lateral ~rame part~ of the bllnd rame, and aonne~ted at their ~ront end~ by a ~oot part 15 extending perpendicula~ly to them.
The foot par~ 15 i8 formed for example a~ a hollow body p~oj~tin~ o~er the ~ssociated end of the blind frame 3. The ~id2 parts 14 are provided at their rear ends with :, ~. el ~ ,-1, T 1~1~ 1 1=; ~ ~ ~:1 .~ T ~ 1 T ,~ C: ~:; T ~ I rl l~ ~ T --fT 3 ~

The ~ide parts 14 and ~he exten~ions 16 are pre~erably simulta~eously formed ~s side blinds, 60 that together with the foot part lS
they form a ~rame which outwardly surrounds the blind xame 3.
The extension~ 1~ at their lower sldes are preferably provided with ~ece~ses or rounded corne~s 17 to allow the turning movement~ abou~ the pi~ot pin 12 a~ shown in FIG. 4.
Each o the side parts 14 i~ provided at its innar side with an upper guide 18 whiah extend~ parallel to i~
longi~udinal direction and ormed as ~ groove or t~e like.
The lateral ends of a conventional shutter web 20 formed for e~ample of shutter bar~ lY, lamellas and the like are slidingly guided in ~he guide~ 18 as ~hown in FIG. 1. It~

The ~pring ~haft can be rota~ably supported in the later~l limiting wal ls o the foot part 15 and fo~med a~ ~ pulling device with a pring ~orce aimed to pull the rolling sh~tter 20 in the direction of the closin~ po~ition, or in o~her wor~, in the direation of the fo~ part 15. The oper~tlon of ~he spring sha~t is analogous to the operatio~ of conventi4nal ~pring shaft~ u~e~ in inside blind~, howeve~, the conventional ratchet device ia not provided, 50 tha~ the x~lling shut~r 20 in ea~h po~ition is undar the ~ction of a ~pring i~orae. The spring ~orce i5 preferably s~lec~ed so to provide substan~ially u~iform spring properties over the whole movement of the rollin~ ~hutter web 20.
A~ lea~t one pro~ection 22 with A guiding pin 23 is pro~ided at the front end o~ the wlndow blade 5 which turns away during opening of the roof window ~ out~ardly. The ~; guiding pin 23 extends in a guidin~ groove 24 formed in the side part 14 and extending p~rallel to the longitudinal airection. Preferably, such guiding plns 2~ are provided at ~- 20 both lateral r~me parts of the win~ow blade 5,and corre-spondlng guiding groo~es 24 ar~ provid~d on ~oth slde parts 14. Th~ ~mblnation of the guiding pin 23 and th~ ~uidin~

$he opening and the clo~ing movemen~s of the xolling ~h~tter we~ ~O can be controlled by a known rollin~ shutter a~tuating device which i~ fixedly connected with ~he rolling S shutter shaft 11. Since the rolling shutter ~haft 11 1~
supported in the fixedly mounted support~ 6 and there~ore does not influence the turning movement o~ t.he side parts ~1, the actuating de~ice can be desi~ned in any des~rable manner.
actua~ing element o the ac~uating devic~ can be guidol ~or ~x~ple eithe~ neaX the rolling shu~ter shaft in the space provided with ~he roof window 2, or placed with ~he aid of the de~iating elements guid~d along the lateral fr~me parts of the bllnd r~me 3, ~t the oppo~ite end of the roof window 2. This i~ schematically ~hown in FI~:S. 2 - 4 by bars 25, lS 26, 27 which are rotatably supported in the blind fxame 3 and lead rom a toothed gear t~nsmission 28 engagin~ the rolling ~hutter shaft 11 in FIG. 3 to an ac~uating elemen~, for example a crank 2~ ~FIGS. 2, ~), a pulling cable and the like.

The op~ration of the inventive rolling ~hutter can be ale~rly reco~nized from FIGS. 2 - 4. In the clo~ed ~5 condi~ion of the window blade 5, ~he side p~rt~ 14 are held ' .: .
2(~09884 1 in their lower turning position by the guiding pins 23. The rollin~ shutter w~b 20 aan be arbitrarily wound or unwound by the rolling shu~ter sha~t 11. The rolling sh~tter web 20 descri~s a convex aurve 21 relati~e to ~he rotary axis 30 of the rolling shutter shaft 11, in the ~p~ce located between the initlal portion of the quides 18 and the rollin~ shut~er sha~t 11. The sa~a is true with ~he open window blade S.
It is ~herefore posslble to arbitrarily turn ~he windo~ blade 5 wlth ths alos~d, partlally open and completely open rolling shut~er web 20, The condition tha~ during openlng a window blade 5 the distance of the axi~ 30 of the rolling shutter sha~t 11 ~rom those ends of the ~uides 18 whiah f~ce toward the rolli~g shutter ~haft 11 i8 always somewhat greatex, posse~ses no disadvantag~ ~ince the piece of the rolling shutter 20 required ox this ~an be w~und with completely cl~ssd xolling ~hut~er web 20 from a remaining reserve located on ~h~ rolling shutter sha~ 11. More~ver~ many rolling shutter web~ 20 are supported in the region of a rollin~
shutter shaft ll by ao called spiral spring, whereby an available rollin~ ~hutter web reserve i~ provided~ Regardless of thi~, t~e diff~rence in the length o~ the rolling shutter web 20 proauced in the open and in the olosod con~itlon o~
th~ window blade S in ~he above describ~ con~tru~tion is maintain~d ~o low that i~ amounts only to sever~al ç~ntimeters.

1 prov$ded ~urning positions of the window blade 5 or the side parts 14, the side par~s 14 are supported by ~he pivot pins 12 ~o that the above mentioned re~r extension~ 18a of the guid~
18 shown in FIGS. 2 and 4 in all these turning po~ition~ have a ~uhs~antially distance h frc~ the axis 30 which at least corre~ponds $ubstantially to the maxi~um ~oil radius o~ the rolling shutter s~aft 11 with completely wound rollin~ ~hutter web 20. In thi~ aase the rolling ~hut~er web 20 aan ~e unwousld independently tangential ly oi~ the xol ling shutter ~haft ll and supplied to the ~uide~ 11 in a ~onvex curve 31 who~e instantaneous coil diameter is equal to the rolling ~hut~er sha t 11, or ln othe~ words, independently of whether the rolling ~hutter 20 is located in its ~ully wound, fully unwound o~ an intermediate wl~ding condition. Since the aonvex curve 31 mo~eover is subætantially maintained in ~11 turnin~ positions of the wide parts 14, the xolllng shu~ter w~b 20 aannot bend upw~rdly also in the aon~entional righ~
running deviae.
The above mentioned di~tan~e h can be for example ~aintaned when the pivot pins 12 ara arxanged in the manner ~hown in FIGS. 2, 4 in ~he ri~ht upper corner o~ th~ support 6, ~nd ~imultaneou~ly the axi~ 30 o~ ~h~ xolllng shutt~r sha~t 11 lle~ sub~tantially in the center, or in oth~r wor~s, b~or~

the side parts 14 or the extensions 16, a plurAlity o~ further . . .
X0(~9884 locations are provided at which ~he pivot pins 12 can b~
~rranged for per~orming ~he de~ired task. Moreover, ~he expre~sions ~substantially" and "somewhat" with respec~ to value h means that ~his value, depending on ~he re~pe~tive cons~ruction, can be somewhat ~maller ~han the maxi~um radiuR
of the rolling shutter ~oil. As ~n be olearly seen fro~n FIGS. 2 and 4, the devioe m~st be advant~geously selected ~o that the respective portion of the rolling shutter web 20 Arranged ~e~ween the rolling shut~er ~haft 11 and t~e initial part of the guide~ 18 is ~uided either in a plane identified b~ the extension~ l~a and extending t~ngentially to the rolling shutter coil ~t the m~ximum coil radius, or describes the convex curve 31 shown in FIGS. ~ and 4.
Fo~ tightly covering ~he ~olling shutter shaft 20 and the rolling shutter coil located on it a~ least with the closed window plate S, the both side parts 14 are connected by ~n upper blind 33 extending over ~he width of the roof window 22, It can ~xtend forwardly at least to the star~ing portion of the guides 18 ~ubstantlally parallel to the blind fr~me 3 ~0 in an unturned condition o~ the side pax~s 14, and provided with sealing lips ex~ending in direction o$ the rolling ~hutter web ~0. ~he rear end 33 o~ the upper ~l~nd 33 i~
prefera~ly angled downwardly so that it cover~ the upp~r end of the lower bl ind 7, and a~ tho ~an~e time does no~ prevent 2~ the turning o~ the ~ide ~rt~ 14 ~hown in FIG. 4. For the :
same reason, the upper edges of the support 6 extend along the curve 10. Alternatingly the lower blind 7 can be shaped correspondingly and provided for example with an impression.
Further blinds can be mounted on the stationary support 6 when desired.
With the aid of the upper blind 33 mounted on the side part 14 and the remaining blinds mounted on the supports 6, the space receiving the rolling shutter shaft 11 is substantially closed in a rain-proof and snow-proof manner, at least when the side parts are located in the non turned condition. Thereby in all turning positions the side parts 14 provide a free space 35 between the guides 18 and the rolling shutter shaft 11 as shown in FIG. 4, which allows the above described guidance of the rolling shutter web 20 along the curve 31 in all turning positions.
The present invention has the advantage that due to the immovable support 6 there are no mounting problems for the actuating device, especially when it must have a hand crank as an actuating element, the rolling shutter web 20 can be mounted in the conventional right running device, no undesirable bending of the rolling shutter web 20 during opening of the window blade 5 occurs, and the part of the total device to be turned has a relatively low weight. More-over, the supports 6 can be fixed above the roof window rigidly on the roof or on the blind frame 3 and therefore zoosas~
forme~ ~o flat ~;at it doe~ not project ~pwardly ~eyond the side parts 14.
The invention is not limited to the above described etnbodinlent and can be rnodified in many diffexent ways. This S is especially true for the rolling shutter actua~ing device u~ilized in each individual case, some auxiliary ~e~ices or the above described spring shaft which can al~o be dispensed with dnd replaced with other means to secure a ~omplete closing of th~ rolling shutter at such angles of inclination o~ th~ ~ide parts 14 at whi~h the rolling shutter web 20 aan not r~n due to i~s gravity force to ths closing posi~ion.
Furthermore, the invention is not limited to the turnable positioning of the structural unit compo~ed of the ~ide ~all~
14, the foot part 15, the upper blind 33, on the same supports 6 which carry the rolling ~hu~te~ shaft 11. As can be ~een partlcularl~ from FIG. 4, the extensions 16 of ~he ~ide wall~
14 c~n be turnably mounted on other ~upport~, ~specially mounted behind the ~upports 6. Further, in deviation from FIGS. ~ - 4 i~ is not neces~ary to mount the upper blind 33 exclu~ively on the side parts 14. Depending on the positi on and arrangement o~ the pivot pin 12, it is further possible ~o mount at least a rear portion o~ the upp~r blind 33 ~ixedly on the support~ 6 or the li~e, and to turn a front ` por~ion with the side walls 14. Finally, the invention aan 2S be used after a ras~eotive adaptation al~o for vertical wall ': ` ' . ` :.

The pre~ent invention relates ~o a rollin~ shutter ~or a cover part of a wall or roof opening, especi~lly for a roof window, provided with a ~urnable blade. More par~icu-larly, it relates to such a rolling shutter which has a rolli~g shutter we~ co~posed of rolling shutter bars or the - like, a rolling ~hutter sha$t for windin~ an un~indin~ the rolling shutter web, two lateral s~ppor~s in whiah ~he rolling ~hu~t~r ~ha~ is ro~atably s~pported, two parallel side bars provided wit~ guides for guiding the rolling shutter web, and 3~pported turnably about an a~is parallel to the rolling ~hutter sh~ft, an upper blind or aovering the rolling ~h~ter web from above, and a rolling ~h~tter actuating deviae.
Rolling shutte~s of the above ment~oned type are known in the art and used in two variants. Th~y serve mainly fo~ ~losing of roo windowx moun~ed in inclined roo~ surfaces and havin~ blind frame~ fixedly mounted in the roof and a windo~ ~lad~ turnable or tilta~le at least ~bout a hori~ontal axis. Such roo~ wind~ws are ~ometimes identi~ied as roof ~esidenae window, roof sura~e window or ~he like.

$he opening and the clo~ing movemen~s of the xolling ~h~tter we~ ~O can be controlled by a known rollin~ shutter a~tuating device which i~ fixedly connected with ~he rolling S shutter shaft 11. Since the rolling shutter ~haft 11 1~
supported in the fixedly mounted support~ 6 and there~ore does not influence the turning movement o~ t.he side parts ~1, the actuating de~ice can be desi~ned in any des~rable manner.
actua~ing element o the ac~uating devic~ can be guidol ~or ~x~ple eithe~ neaX the rolling shu~ter shaft in the space provided with ~he roof window 2, or placed with ~he aid of the de~iating elements guid~d along the lateral fr~me parts of the bllnd r~me 3, ~t the oppo~ite end of the roof window 2. This i~ schematically ~hown in FI~:S. 2 - 4 by bars 25, lS 26, 27 which are rotatably supported in the blind fxame 3 and lead rom a toothed gear t~nsmission 28 engagin~ the rolling ~hutter shaft 11 in FIG. 3 to an ac~uating elemen~, for example a crank 2~ ~FIGS. 2, ~), a pulling cable and the like.

The rolling sh~tter web 20 descri~s a convex aurve 21 relati~e to ~he rotary axis 30 of the rolling shutter shaft 11, in the ~p~ce located between the initlal portion of the quides 18 and the rollin~ shut~er sha~t 11. The sa~a is true with ~he open window blade S.
It is ~herefore posslble to arbitrarily turn ~he windo~ blade 5 wlth ths alos~d, partlally open and completely open rolling shut~er web 20, The condition tha~ during openlng a window blade 5 the distance of the axi~ 30 of the rolling shutter sha~t 11 ~rom those ends of the ~uides 18 whiah f~ce toward the rolli~g shutter ~haft 11 i8 always somewhat greatex, posse~ses no disadvantag~ ~ince the piece of the rolling shutter 20 required ox this ~an be w~und with completely cl~ssd xolling ~hut~er web 20 from a remaining reserve located on ~h~ rolling shutter sha~ 11.

1 prov$ded ~urning positions of the window blade 5 or the side parts 14, the side par~s 14 are supported by ~he pivot pins 12 ~o that the above mentioned re~r extension~ 18a of the guid~
18 shown in FIGS. 2 and 4 in all these turning po~ition~ have a ~uhs~antially distance h frc~ the axis 30 which at least corre~ponds $ubstantially to the maxi~um ~oil radius o~ the rolling shutter s~aft 11 with completely wound rollin~ ~hutter web 20. In thi~ aase the rolling ~hut~er web 20 aan ~e unwousld independently tangential ly oi~ the xol ling shutter ~haft ll and supplied to the ~uide~ 11 in a ~onvex curve 31 who~e instantaneous coil diameter is equal to the rolling ~hut~er sha t 11, or ln othe~ words, independently of whether the rolling ~hutter 20 is located in its ~ully wound, fully unwound o~ an intermediate wl~ding condition. Since the aonvex curve 31 mo~eover is subætantially maintained in ~11 turnin~ positions of the wide parts 14, the xolllng shu~ter w~b 20 aannot bend upw~rdly also in the aon~entional righ~

the side parts 14 or the extensions 16, a plurAlity o~ further . . .
X0(~9884 locations are provided at which ~he pivot pins 12 can b~
~rranged for per~orming ~he de~ired task. Moreover, ~he expre~sions ~substantially" and "somewhat" with respec~ to value h means that ~his value, depending on ~he re~pe~tive cons~ruction, can be somewhat ~maller ~han the maxi~um radiuR
of the rolling shutter ~oil. As ~n be olearly seen fro~n FIGS. 2 and 4, the devioe m~st be advant~geously selected ~o that the respective portion of the rolling shutter web 20 Arranged ~e~ween the rolling shut~er ~haft 11 and t~e initial part of the guide~ 18 is ~uided either in a plane identified b~ the extension~ l~a and extending t~ngentially to the rolling shutter coil ~t the m~ximum coil radius, or describes the convex curve 31 shown in FIGS. ~ and 4.
Fo~ tightly covering ~he ~olling shutter shaft 20 and the rolling shutter coil located on it a~ least with the closed window plate S, the both side parts 14 are connected by ~n upper blind 33 extending over ~he width of the roof window 22, It can ~xtend forwardly at least to the star~ing portion of the guides 18 ~ubstantlally parallel to the blind fr~me 3 ~0 in an unturned condition o~ the side pax~s 14, and provided with sealing lips ex~ending in direction o$ the rolling ~hutter web ~0. ~he rear end 33 o~ the upper ~l~nd 33 i~
prefera~ly angled downwardly so that it cover~ the upp~r end of the lower bl ind 7, and a~ tho ~an~e time does no~ prevent 2~ the turning o~ the ~ide ~rt~ 14 ~hown in FIG. 4. For the :
same reason, the upper edges of the support 6 extend along the curve 10. Alternatingly the lower blind 7 can be shaped correspondingly and provided for example with an impression.
Further blinds can be mounted on the stationary support 6 when desired.
With the aid of the upper blind 33 mounted on the side part 14 and the remaining blinds mounted on the supports 6, the space receiving the rolling shutter shaft 11 is substantially closed in a rain-proof and snow-proof manner, at least when the side parts are located in the non turned condition. Thereby in all turning positions the side parts 14 provide a free space 35 between the guides 18 and the rolling shutter shaft 11 as shown in FIG. 4, which allows the above described guidance of the rolling shutter web 20 along the curve 31 in all turning positions.
The present invention has the advantage that due to the immovable support 6 there are no mounting problems for the actuating device, especially when it must have a hand crank as an actuating element, the rolling shutter web 20 can be mounted in the conventional right running device, no undesirable bending of the rolling shutter web 20 during opening of the window blade 5 occurs, and the part of the total device to be turned has a relatively low weight. More-over, the supports 6 can be fixed above the roof window rigidly on the roof or on the blind frame 3 and therefore zoosas~
forme~ ~o flat ~;at it doe~ not project ~pwardly ~eyond the side parts 14.
The invention is not limited to the above described etnbodinlent and can be rnodified in many diffexent ways. This S is especially true for the rolling shutter actua~ing device u~ilized in each individual case, some auxiliary ~e~ices or the above described spring shaft which can al~o be dispensed with dnd replaced with other means to secure a ~omplete closing of th~ rolling shutter at such angles of inclination o~ th~ ~ide parts 14 at whi~h the rolling shutter web 20 aan not r~n due to i~s gravity force to ths closing posi~ion.
Furthermore, the invention is not limited to the turnable positioning of the structural unit compo~ed of the ~ide ~all~
14, the foot part 15, the upper blind 33, on the same supports 6 which carry the rolling ~hu~te~ shaft 11. As can be ~een partlcularl~ from FIG. 4, the extensions 16 of ~he ~ide wall~
14 c~n be turnably mounted on other ~upport~, ~specially mounted behind the ~upports 6. Further, in deviation from FIGS. ~ - 4 i~ is not neces~ary to mount the upper blind 33 exclu~ively on the side parts 14. Depending on the positi on and arrangement o~ the pivot pin 12, it is further possible ~o mount at least a rear portion o~ the upp~r blind 33 ~ixedly on the support~ 6 or the li~e, and to turn a front ` por~ion with the side walls 14. Finally, the invention aan 2S be used after a ras~eotive adaptation al~o for vertical wall ': ` ' . ` :.
