Description
11 LIF"PING CURTAIN IJ00R
The presemt invention relates to doors for industrial buildings and premises, hangars and warehouses, in which the door is constituted by a flexible, secn3.-rigid, or rigid, curtain which is foldable or rollable and wtxich opens a doorway by being .raised, and whl.ct~ closes it by be~.ng lowexed; w.itai t:he~
curtain being stored at the top of the door when raised, eitPaer by being rolled up or by being folded.
I3ACfCGROUNf) OF TffE INVENTION
a0 Some doors of this type are exposed to the actioru of the wind. Various means are known for preventing cna;jor deformation which could damage 'the door or dam it. The vertical edges of the curtain may have a portion of greater thickness or skids fixed thereon for sliding in a channel (li)Ge sails on a boat):
l.5 Vertically spaced-apart horizontal reinforcing bars are also used with their ends sliding in slideways. The invewtion relaters, in particular, to a lifting curtain door comprising a frame constituted by two vertical side uprigyts interconnected at the top by a cross-member, each of the said side uprights 2.0 comprising or including a slideway with each slideway having a guide wall on either side of 'the plane of the curtain with the curtain being gathored together at the top by rolling up or by folding, the curtain being reinforced by horizowtal bars whose ends slide in the said slideways.
25 These various systems scoffer from the drawback that during various kinds of traffic accident, when a vehicle stri)ces the door before the door is fully opened, the door is damaged.
Indeed the door is often ~arrnned and it is necessary to dismount the door. Traffic is interrupted and repairs may be expensive, 30 the cuxtain may be torn; a twisted bar may need extracsting; etc.
The Applicant has already proposed a reinforcing bar device in which the ends sliding in the slideways include a section of weakness. As a .result, when there is a shock against tree bar, it breaks at the end and -the door can still be :35 operated. 'I'taere is merely 'the end of one of 'the bars that is no longer guide~;d and this is easily repaired by replacing -the broken part.
Although the above system is advantageous in many applications, it is not suitable for all applications, and a certain amount of time must nevertheless be allowed for performing repairs.
The object of the present invention is to avoid the door being damaged when a vehicle strikes against the curtain beforE: it is fully opened, or when excessive wind force is applied thereto, so that under the effect of such a shock, the door, or at least one of the door components, i:~ subjected to non-permanent deformation, thereby enabling the door to return to its proper position merely by being operated and without any other action being taken.
SUMMARY OF THE INVENTION
Therefore, in accordance with the present invention there is provided a lifting curtain door comprising a frame constituted by two vertical side uprights interconnected at their top ends by a cross member, said side uprights each constituting or including a slideway, each slideway having a guide wall on either side of the plane of the curtain, which curtain may be gathered together at th.e top of the door by being rolled up or folded, the curtain being reinforced by horizontal bars whose ends slide in the said slideways, wherein at least one of the bar's has sufficient flexibility at at least one portion of its Length to enable it to escape from at least one of the sli.deways in the event of an abnormal transverse force being applied to the bar, without the bar being deformed permanently which could impede subsequent operation of the curtain.
In one embodiment, at least one bar is flexible overall.
2a ' In a varuant, at least one bar is flexible in the middle.
In another embodiment, at least one bar has deformable ends.
The above dispositions thus enable the door to withstand a shock or abnormal thrust without being damaged. However, iii is still necessary, after a bar has escaped from its sl:ideways, to put the bar back into place. The invention also provides means for facilitating returning a bar into slideways from which it has escaped.
Advantageously, the invention provides for a bar to be returned into its slideways automatically without requiring special ar_tion to be taken, either while the door is being raised, or else while the door is being lowered again after it has been opened.
'fo this end, in one embodiment of the inventian 'the outside walls of thre slideways or of walls fixed to the slideways define vertical plaa~es tkrat sa.ope re lattve to the plane of the door, with the -two walls of each sl.ideway extending towards each other -towards 'the center of 'the door.
Advantageously, tk~e slideway is lirnited vertical7.y at a level situated beneath -the bottonunost bar when the curtain is raised, and has an upwardly flared opening beneath said bar when in its raised position such that the bottommost bar and :LO subsequently all the other bars engage in the slideway while the cur-tain is being lowered.
In an advantageous form of the invention, tk~e wall of the slideway or the wall of the upright including 'the slideway includes at least one moving wall elemewt capable of deforming elastically so as to form a patki enabling an end of the bar to pass from the outside of the slideway to the inside, bu-t not in the opposite direction.
In another particularly advantageous embodiment, in which neither the uprigk~ts nor tha slideways include any moving ?.0 parts, at least one of the ot.rtside walls of 'the uprights including the slideways is provided with a guide pro~ecttrrg from said wall and directed generally upwards 'towards the opening of the slideway, said guide extending over at least a portion of the wj.dth of the said wall to the edge of the slideway opening so as to return any bar end 'that pray have escaped to the slideway as f.t is pulled upwards, with -the bar being deformed so as -to be shortened by bending or by contraction (e. g, by telescopic shortening).

:~.c~ r~Ef~zL~n nssc~Ip~rION
Figure 1 is a perspective view of one embodiment of a door frame for a curtain type door of the invention. The frame comprises two vertical side uprights 1 and 2 :intercomrrected at -their top ends by a cross bar 3 constituting a lintel.
.15 The cross section of each upright is in the form of a pentagon whicYr is open at one of :t-ts vertices, having a base _a, two sides b extending perpendicularly to the base, and 'two sides c extending -towards eac2r other and leaving a gap d between their ad,~acen-t ends, thereby forming -the opening to a 20 slideway 2.1 in each o.f the uprights and suitabae for receiving a corresponding edge of the curtain 4,togettrer with the ends of curtain :reinforcing bars 5. Corresponding sides may be equal in sizes or otherwise. In order to make the drawings easier to understand, the curta3.n is assumed to be made of transparent 2.5 material (which is possible in practice and is indeed lane in same cases).
Figure 2 is a horizontal section view through an upright and through one end of a curtain reinforcing bar, showing how the bar is disposed in the slideway.
7lccord~.ng to the invention, the reinforcing bars are made sufficiently flexible that when subjected to thrust they are capable of leaving the guide groove prior to being subjected to permanewt deformation or to sub;jectirrg the guide groove itself to pexmanerrt deformation. This may be obtained by tire .bar.
:35 ass~:mbly being f:lescible. Flexibility may be provided by means of a glass fiber reinforced plastic 'tube capable of absorbing considerable non-permanent defo.nnation so that one or both of ~~- ~'' ~'k. ~~' .~1.'~.~ 'J
its ealds may leave the groove withowt permanent deforanation ar.
breakage. Flexibility may be limited to a portion of the bar, e.g. its middle, or to its ends. The middle of the bar may be cons tittzted by a snore flex.i.ble portion, e.g, a resi.l.ierrt sleeve 5 or a coil spring, thereby enabling the bar to fold. The bar 5 array also be provided with endpieces 6 made of flexible material, e.g. rubber, which are engaged in 'the two ends of the bar which tray then be a 'tube made of metal or any othex material. The endpiece may be semirigid so as to withstand LU normal ~ttnrusts ( wind ) or thrus is sligxntly higher than normal, and may inolude a zone 6a of narrowing enabling it to bend in the evet~t of a sudden thrust or a thntst which is very strong.
Figure 3 is a section through another etnbodimerrt of the end of a bar. The tiorizowtal reinforcing bar lU is constituted by a tube 1Z with a mandrel 13 received in the end ti~ereof, aIld with a spring 1~ engaged on tire mandrel. The d~.mens3.ons of the mandrel arid of the spring are selected so thtat these paris era capable of holding 'together withotat additional means merely by being pushed 'together as shown. It is preferable, although ?,U clearly net essential, to avoid any need for .riveting, welding, eta. ... operations. In a variant, the spring could be engaged inside the tube 12. Similarly, an endpiece 15 is fisted 'to 'the other end of the spring. Because of. material wear and because of the need to reduce noise ixi operation, it is preferable to ensure that tYte spring does not rub directly against the slide-way 21. It will :readily be understood that if strffi.a.ierttly large force is applied to the bar, then its end, i.e, the endpiece 15, may leave the slideway because the end of tt'te bar deforms, i.e. because 'the spring 14 folds without being damaged. Conversely, after it has escaped from the slideway, the end of the bar l.s easily returned into the slideway, e.g.
by applying adequate thrust or by manually folding over 'the er~dpiece 15 to cause it to penetrate back into 'the slideway.
Under such conditions, in the event of e~ccessive f.-orce ~5 being applied to a door, t'he bars escape .from 'the slideways because of'~tt~e fa.erci'bility of the bard 5, :t0.
w~c. I~ ;:~
1.t j.s advantageous to rrvo:id gray rneed for manual intervention to put tt~e system back into place. The d:Lrections in wtaich the faces c of the upri.gtnts constituting the slideways extend facilitate reinserting ttae bars in the slideways while the curtain is being raised under ttie effect of upwards traction exerted on -ttie bans by the otartain. Tt is a3.so advantageous to provide complementary di,sposittons for. forcing the ends of the bars to go basic into the slideways. To this end, in an embodiment of the invention shown in Figure ~ ( cahich l.U is a section view on a vertical plane perpendicular to the curtain ~ and ta)cen irz the middle thereof ), -the slideways 21 may come to an end a little below the volurrle in which the curtain is stored, e.g. by being rolled up as shown in section in the figure. The slideway ends may have upwardly flared ends 21a so that when the curtain is lowered again, the acids of -the bar naturally engage in the slideways 21.
In order to facilitate returning ttre bar ends to ttre:ir proper planes while the curtain is being raised, reinsertion ramps or recentering surfaces as are provided above the flare 2U of -the slideway and beneatta tire curtain storage zone sucta that;
when the curtain is raised, the ends of the bars a.re returroecl to the axis of the curtain-storage zone.
'fhe spice between the flard 21a and tt~e reinsertion ramp 7 forms a reinsertion window. ,~ plurality of them may be 5 provided up the tieigtrt of the curtain.
The apparatus desoribed above with reference to Figure ~1 tras a gap in the slideway at each reinsertion ramp. While the curtain is being lowered and going past a gap, the wind flay move it off axis so that it continues to go down outside the UU slideways. Such apparatus is therefore not sui~tab7.e for. being placed in locations that m~,y be exposed to the wind or to large drafts. Figures 5 'to f3 show variant enrbodimerrts of the invention that avoid this limitation.
'These variants all inc:luc7e a slideway 21 as described above.
U ~ The slideway 21 ~.s essewt~.ally defined by two parallel plane walls 22 and 23 cm either side of the curtain plane, and delim-9.-ting an interst.ic:ial space in which 'the ends of the horizontal.

The bottam of the slideway groove may be closed by a wall 24, 'thereby improving stiffness and protPCting the :lrzsi.dc~ of t:he sli.deway :fram dust: arid othwr foreign bodies. According to a characteristic of 'the irmention, the slideways are coated o« tt~e outsides o:~ their, sloping faces 25 and 26 ( protective walls ) , thereby facil3.~ta ting reinsertion of escaped bar ends back into 'the slideways. A slideway generally includes ac7ditiazaal side walls 27 and 2f3 arid a bottom :L0 wall 29 so as to constitwte a rigid assembly.
Tn -the eanbodimezot shown in part and in diagranunati.c perspective in Figu:ce 5, -the slideway 21 does nit include any gaps. However a reinsertion ramp 35 is provided, preferably near the top of 'the char. When a bar has escaped from ~t;He t.'S slideway 21, ttyen tl~e end of ttie bar will rub against the surface 25 or 27 of the section member surrounding the slideway. On reaching the ramp 35, the end of the bar is engaged thereon by ~tractian due to the curtain beirxg ra:Lsed, and also by the effect of the inclined guide 33. ~i~he end of 2.() the bar moves up the ramp 35 which causes the bar ~to shor. tem.
This may be achieved by the bar' bending, or if it is made as shown in Figure 3 or 9, by a spring deforming or contracting.
The end of the bar is guided to the end 35A of the ramp, after which it expands sa as to return inta the slideway 21 > since 25 the slideway has no gaps, vthe bars are prevented from escaping from the slideway wtxile the curtain is being lowered even if the curtain is sub;Jected to strong wind.
In order to facilitate shortening 'the bar, so as to'allow it to slide easily along 'the guide 33A, and so as 'to facilitate :30 reinsertion 3.nto ttie slideway, the ends of 'the bars may be telescopic, as shown in Figure 9 for the ba.r 20.

need Trot be flexa.ble. :Ln order to enable taw bar to escape from its slideways under the e:Efect of an abnormal force, tare bar. must be fheactbl.e overall. or.~ else l.t must include a zone, e.g. a cant:ral zone, wtrarh it parti.aul.ar.ty f:lex:i.ble. ttcrwc:ver, OIICe SUCK a bar has escaped from the slideway, it can clearly be seen -that it can be returned thereto by pushing the piston 2!1 into the sleeve 17, e.g. by hand or else whale the curtain is being raised by virtue of. a suitable guide ramp onto which the piston is directed during curtain raising. while tare bar 1() is being raised, the piston X31 is thrust by 'the rapp into the tube 12 and is guided to the edge of 'the slideway. alt ttris moment, the spring 19 is free 'to expand and the piston is re-engaged in tire slideway. It is 'then no longer capable of escaping therefrom merely by being lowered agair>> >
In Figure 5, the guide ramp is shown as being a small hollow relative to the sloping surface 25. This is not essential..
7.'he ramp may be constituted solely by the pro~eoting rim 33A of 'the reinsertion guide. In ttris case, the guide rnay be fixed or displaceable or removable. Irr this case, 'the surface 2,5 may ~ also be parallel -to the bottam 29 of the slideway.
In a variant embodimerut, in order to facilitate reinsertion of bars that are simpler in struatuz-e, tire ramp 35 may be displaceable so as to 'temporarily open a window in the wall 23 of 'the slideway. For example, the ramp may be hinged about tare bottom edge 36, and a section 38 of the wall 23 may be displaceable in the direction of arrow 37. Figure 6 is a section on line VI-VI of Figure 5, and shows 'the ramp in its nornval position at reference 35, and irx its pushed down position at reference 35' . The extent 'to which ~t:he sl:ideway W can be pustred down may be defined as a function o.f tare nature of the bars and of the ease with which ttrey bend or of tareir ability to shorten. In practice, this local mobility may be obtained by forming a cut--out ~.n the wall of the upright.
In another ~~nY~odiment of floe inverrtian, irr order to 3 5 prevent bars from escaping from the slideway while the curtain is being lowered, the reinsertion window 32 (riglrthand portion of Figure 7 ) may be closed by a defoxmable or Cringed shr.rtter 40 s r 1 r~ -~ 1 r., ~ ~ ~.,. n ( lef thand side of Figure '7 ) which is urged when 3.n its rest positton to remain in a plane parallel ~to the curtain but which is capable of occupying a position 40' by deforming into the sl.ic9eway under thrust front the end o~ a bar ag pu:ll.ed by tine curtain being raised.

The presemt invention relates to doors for industrial buildings and premises, hangars and warehouses, in which the door is constituted by a flexible, secn3.-rigid, or rigid, curtain which is foldable or rollable and wtxich opens a doorway by being .raised, and whl.ct~ closes it by be~.ng lowexed; w.itai t:he~
curtain being stored at the top of the door when raised, eitPaer by being rolled up or by being folded.
I3ACfCGROUNf) OF TffE INVENTION
a0 Some doors of this type are exposed to the actioru of the wind. Various means are known for preventing cna;jor deformation which could damage 'the door or dam it. The vertical edges of the curtain may have a portion of greater thickness or skids fixed thereon for sliding in a channel (li)Ge sails on a boat):
l.5 Vertically spaced-apart horizontal reinforcing bars are also used with their ends sliding in slideways. The invewtion relaters, in particular, to a lifting curtain door comprising a frame constituted by two vertical side uprigyts interconnected at the top by a cross-member, each of the said side uprights 2.0 comprising or including a slideway with each slideway having a guide wall on either side of 'the plane of the curtain with the curtain being gathored together at the top by rolling up or by folding, the curtain being reinforced by horizowtal bars whose ends slide in the said slideways.
25 These various systems scoffer from the drawback that during various kinds of traffic accident, when a vehicle stri)ces the door before the door is fully opened, the door is damaged.
Indeed the door is often ~arrnned and it is necessary to dismount the door. Traffic is interrupted and repairs may be expensive, 30 the cuxtain may be torn; a twisted bar may need extracsting; etc.
The Applicant has already proposed a reinforcing bar device in which the ends sliding in the slideways include a section of weakness. As a .result, when there is a shock against tree bar, it breaks at the end and -the door can still be :35 operated. 'I'taere is merely 'the end of one of 'the bars that is no longer guide~;d and this is easily repaired by replacing -the broken part.
Although the above system is advantageous in many applications, it is not suitable for all applications, and a certain amount of time must nevertheless be allowed for performing repairs.
The object of the present invention is to avoid the door being damaged when a vehicle strikes against the curtain beforE: it is fully opened, or when excessive wind force is applied thereto, so that under the effect of such a shock, the door, or at least one of the door components, i:~ subjected to non-permanent deformation, thereby enabling the door to return to its proper position merely by being operated and without any other action being taken.
SUMMARY OF THE INVENTION
Therefore, in accordance with the present invention there is provided a lifting curtain door comprising a frame constituted by two vertical side uprights interconnected at their top ends by a cross member, said side uprights each constituting or including a slideway, each slideway having a guide wall on either side of the plane of the curtain, which curtain may be gathered together at th.e top of the door by being rolled up or folded, the curtain being reinforced by horizontal bars whose ends slide in the said slideways, wherein at least one of the bar's has sufficient flexibility at at least one portion of its Length to enable it to escape from at least one of the sli.deways in the event of an abnormal transverse force being applied to the bar, without the bar being deformed permanently which could impede subsequent operation of the curtain.
In one embodiment, at least one bar is flexible overall.
2a ' In a varuant, at least one bar is flexible in the middle.
In another embodiment, at least one bar has deformable ends.
The above dispositions thus enable the door to withstand a shock or abnormal thrust without being damaged. However, iii is still necessary, after a bar has escaped from its sl:ideways, to put the bar back into place. The invention also provides means for facilitating returning a bar into slideways from which it has escaped.
Advantageously, the invention provides for a bar to be returned into its slideways automatically without requiring special ar_tion to be taken, either while the door is being raised, or else while the door is being lowered again after it has been opened.
'fo this end, in one embodiment of the inventian 'the outside walls of thre slideways or of walls fixed to the slideways define vertical plaa~es tkrat sa.ope re lattve to the plane of the door, with the -two walls of each sl.ideway extending towards each other -towards 'the center of 'the door.

:~.c~ r~Ef~zL~n nssc~Ip~rION
Figure 1 is a perspective view of one embodiment of a door frame for a curtain type door of the invention. The frame comprises two vertical side uprights 1 and 2 :intercomrrected at -their top ends by a cross bar 3 constituting a lintel.
.15 The cross section of each upright is in the form of a pentagon whicYr is open at one of :t-ts vertices, having a base _a, two sides b extending perpendicularly to the base, and 'two sides c extending -towards eac2r other and leaving a gap d between their ad,~acen-t ends, thereby forming -the opening to a 20 slideway 2.1 in each o.f the uprights and suitabae for receiving a corresponding edge of the curtain 4,togettrer with the ends of curtain :reinforcing bars 5. Corresponding sides may be equal in sizes or otherwise. In order to make the drawings easier to understand, the curta3.n is assumed to be made of transparent 2.5 material (which is possible in practice and is indeed lane in same cases).
Figure 2 is a horizontal section view through an upright and through one end of a curtain reinforcing bar, showing how the bar is disposed in the slideway.
7lccord~.ng to the invention, the reinforcing bars are made sufficiently flexible that when subjected to thrust they are capable of leaving the guide groove prior to being subjected to permanewt deformation or to sub;jectirrg the guide groove itself to pexmanerrt deformation. This may be obtained by tire .bar.
:35 ass~:mbly being f:lescible. Flexibility may be provided by means of a glass fiber reinforced plastic 'tube capable of absorbing considerable non-permanent defo.nnation so that one or both of ~~- ~'' ~'k. ~~' .~1.'~.~ 'J
its ealds may leave the groove withowt permanent deforanation ar.
breakage. Flexibility may be limited to a portion of the bar, e.g. its middle, or to its ends. The middle of the bar may be cons tittzted by a snore flex.i.ble portion, e.g, a resi.l.ierrt sleeve 5 or a coil spring, thereby enabling the bar to fold. The bar 5 array also be provided with endpieces 6 made of flexible material, e.g. rubber, which are engaged in 'the two ends of the bar which tray then be a 'tube made of metal or any othex material. The endpiece may be semirigid so as to withstand LU normal ~ttnrusts ( wind ) or thrus is sligxntly higher than normal, and may inolude a zone 6a of narrowing enabling it to bend in the evet~t of a sudden thrust or a thntst which is very strong.
Figure 3 is a section through another etnbodimerrt of the end of a bar. The tiorizowtal reinforcing bar lU is constituted by a tube 1Z with a mandrel 13 received in the end ti~ereof, aIld with a spring 1~ engaged on tire mandrel. The d~.mens3.ons of the mandrel arid of the spring are selected so thtat these paris era capable of holding 'together withotat additional means merely by being pushed 'together as shown. It is preferable, although ?,U clearly net essential, to avoid any need for .riveting, welding, eta. ... operations. In a variant, the spring could be engaged inside the tube 12. Similarly, an endpiece 15 is fisted 'to 'the other end of the spring. Because of. material wear and because of the need to reduce noise ixi operation, it is preferable to ensure that tYte spring does not rub directly against the slide-way 21. It will :readily be understood that if strffi.a.ierttly large force is applied to the bar, then its end, i.e, the endpiece 15, may leave the slideway because the end of tt'te bar deforms, i.e. because 'the spring 14 folds without being damaged. Conversely, after it has escaped from the slideway, the end of the bar l.s easily returned into the slideway, e.g.
by applying adequate thrust or by manually folding over 'the er~dpiece 15 to cause it to penetrate back into 'the slideway.
Under such conditions, in the event of e~ccessive f.-orce ~5 being applied to a door, t'he bars escape .from 'the slideways because of'~tt~e fa.erci'bility of the bard 5, :t0.
w~c. I~ ;:~
1.t j.s advantageous to rrvo:id gray rneed for manual intervention to put tt~e system back into place. The d:Lrections in wtaich the faces c of the upri.gtnts constituting the slideways extend facilitate reinserting ttae bars in the slideways while the curtain is being raised under ttie effect of upwards traction exerted on -ttie bans by the otartain. Tt is a3.so advantageous to provide complementary di,sposittons for. forcing the ends of the bars to go basic into the slideways. To this end, in an embodiment of the invention shown in Figure ~ ( cahich l.U is a section view on a vertical plane perpendicular to the curtain ~ and ta)cen irz the middle thereof ), -the slideways 21 may come to an end a little below the volurrle in which the curtain is stored, e.g. by being rolled up as shown in section in the figure. The slideway ends may have upwardly flared ends 21a so that when the curtain is lowered again, the acids of -the bar naturally engage in the slideways 21.
In order to facilitate returning ttre bar ends to ttre:ir proper planes while the curtain is being raised, reinsertion ramps or recentering surfaces as are provided above the flare 2U of -the slideway and beneatta tire curtain storage zone sucta that;
when the curtain is raised, the ends of the bars a.re returroecl to the axis of the curtain-storage zone.
'fhe spice between the flard 21a and tt~e reinsertion ramp 7 forms a reinsertion window. ,~ plurality of them may be 5 provided up the tieigtrt of the curtain.
The apparatus desoribed above with reference to Figure ~1 tras a gap in the slideway at each reinsertion ramp. While the curtain is being lowered and going past a gap, the wind flay move it off axis so that it continues to go down outside the UU slideways. Such apparatus is therefore not sui~tab7.e for. being placed in locations that m~,y be exposed to the wind or to large drafts. Figures 5 'to f3 show variant enrbodimerrts of the invention that avoid this limitation.
'These variants all inc:luc7e a slideway 21 as described above.
U ~ The slideway 21 ~.s essewt~.ally defined by two parallel plane walls 22 and 23 cm either side of the curtain plane, and delim-9.-ting an interst.ic:ial space in which 'the ends of the horizontal.

re:lzzforcing bars of t:he curtain door nave, saj.d ends being guided by the walls 22 and 23. The bottam of the slideway groove may be closed by a wall 24, 'thereby improving stiffness and protPCting the :lrzsi.dc~ of t:he sli.deway :fram dust: arid othwr foreign bodies. According to a characteristic of 'the irmention, the slideways are coated o« tt~e outsides o:~ their, sloping faces 25 and 26 ( protective walls ) , thereby facil3.~ta ting reinsertion of escaped bar ends back into 'the slideways. A slideway generally includes ac7ditiazaal side walls 27 and 2f3 arid a bottom :L0 wall 29 so as to constitwte a rigid assembly.
Tn -the eanbodimezot shown in part and in diagranunati.c perspective in Figu:ce 5, -the slideway 21 does nit include any gaps. However a reinsertion ramp 35 is provided, preferably near the top of 'the char. When a bar has escaped from ~t;He t.'S slideway 21, ttyen tl~e end of ttie bar will rub against the surface 25 or 27 of the section member surrounding the slideway. On reaching the ramp 35, the end of the bar is engaged thereon by ~tractian due to the curtain beirxg ra:Lsed, and also by the effect of the inclined guide 33. ~i~he end of 2.() the bar moves up the ramp 35 which causes the bar ~to shor. tem.
This may be achieved by the bar' bending, or if it is made as shown in Figure 3 or 9, by a spring deforming or contracting.
The end of the bar is guided to the end 35A of the ramp, after which it expands sa as to return inta the slideway 21 > since 25 the slideway has no gaps, vthe bars are prevented from escaping from the slideway wtxile the curtain is being lowered even if the curtain is sub;Jected to strong wind.
In order to facilitate shortening 'the bar, so as to'allow it to slide easily along 'the guide 33A, and so as 'to facilitate :30 reinsertion 3.nto ttie slideway, the ends of 'the bars may be telescopic, as shown in Figure 9 for the ba.r 20.

need Trot be flexa.ble. :Ln order to enable taw bar to escape from its slideways under the e:Efect of an abnormal force, tare bar. must be fheactbl.e overall. or.~ else l.t must include a zone, e.g. a cant:ral zone, wtrarh it parti.aul.ar.ty f:lex:i.ble. ttcrwc:ver, OIICe SUCK a bar has escaped from the slideway, it can clearly be seen -that it can be returned thereto by pushing the piston 2!1 into the sleeve 17, e.g. by hand or else whale the curtain is being raised by virtue of. a suitable guide ramp onto which the piston is directed during curtain raising. while tare bar 1() is being raised, the piston X31 is thrust by 'the rapp into the tube 12 and is guided to the edge of 'the slideway. alt ttris moment, the spring 19 is free 'to expand and the piston is re-engaged in tire slideway. It is 'then no longer capable of escaping therefrom merely by being lowered agair>> >
In Figure 5, the guide ramp is shown as being a small hollow relative to the sloping surface 25. This is not essential..
7.'he ramp may be constituted solely by the pro~eoting rim 33A of 'the reinsertion guide. In ttris case, the guide rnay be fixed or displaceable or removable. Irr this case, 'the surface 2,5 may ~ also be parallel -to the bottam 29 of the slideway.
In a variant embodimerut, in order to facilitate reinsertion of bars that are simpler in struatuz-e, tire ramp 35 may be displaceable so as to 'temporarily open a window in the wall 23 of 'the slideway. For example, the ramp may be hinged about tare bottom edge 36, and a section 38 of the wall 23 may be displaceable in the direction of arrow 37. Figure 6 is a section on line VI-VI of Figure 5, and shows 'the ramp in its nornval position at reference 35, and irx its pushed down position at reference 35' . The extent 'to which ~t:he sl:ideway W can be pustred down may be defined as a function o.f tare nature of the bars and of the ease with which ttrey bend or of tareir ability to shorten. In practice, this local mobility may be obtained by forming a cut--out ~.n the wall of the upright.
In another ~~nY~odiment of floe inverrtian, irr order to 3 5 prevent bars from escaping from the slideway while the curtain is being lowered, the reinsertion window 32 (riglrthand portion of Figure 7 ) may be closed by a defoxmable or Cringed shr.rtter 40 s r 1 r~ -~ 1 r., ~ ~ ~.,. n ( lef thand side of Figure '7 ) which is urged when 3.n its rest positton to remain in a plane parallel ~to the curtain but which is capable of occupying a position 40' by deforming into the sl.ic9eway under thrust front the end o~ a bar ag pu:ll.ed by tine curtain being raised. Once tli~ curtain has been gatlaared togetkter at the top of the door, the stxwt-ter ~0 returns to i is position lying flush with 'the wall 22 of the sl.ideway and the curtain may be lowered again without running any ris)c of it escaping from the sll.deway.
1C> Tkte shutter 40 may be a flexible metal blada fixed at one end by means of r.i.ve is . 111 t;er. ua tavely it may be formed mere l.y by forming a cut-out in the wall of the slideway, depending on the resilient nature of the material from which 'the sli.deway is made .
x.11 of the bars may be made in 'the same way. However it is also possible to provide only one bar in accordar~ae with 'the invention, e.g. tits bar which is in greatest danger, or the bottom bar.
