Specific embodiment

A kind of exemplary door curtain with recoverable disengaging situation is described herein, it is included in normal operating During guide the first device of lateral edges of curtain and for guiding curtain edge during single repacking operation second only Vertical device.In some instances, first device includes the track of a vertical rows button of the guiding on curtain.In some examples In, second device includes being located at the roller near track upper end and the elongated pearl on the lateral edges of curtain.In some instances, In normal operating, button slides along the track, and pearl moves through roller and without substantial exposure between pearl and roller. In some examples, during disengaging, " bullet " out from track for button.In some instances, after disengaging, curtain raise and under Curtain is directed upwardly to upper winding drum and then return downwards, button is re-fitted in track by drop, roller engagement pearl first.In addition, Exemplary rolling screen door disclosed herein and door method are included for straighteing the door curtain for being moved out of and being turned down to help curtain certainly Dynamic refitting returns to the device in its guide rail.In some instances, the device for straighteing curtain includes the expansion of roller form Device.After curtain disengaging accident, a part for curtain is not only pulled out from its guide rail but also turned down onto itself, power Driver element makes the curtain being moved out of raise upwardly toward its open position.When curtain is raised, turnover part is pulled against on roller. Roller engagement turns down part and launches the turnover part, so as to the curtain being straightened can easily be installed onto its guide rail In road.

Specifically, Fig. 1-2 0 is shown for optionally stopping and getting out of the way the He of 12 example door of doorway 10 on wall 17 Illustrative methods.During normal door operation, curtain 14 is along track 16 (for example, the first track 16a and the second track 16b) To open and close door 10, wherein Fig. 1,12 and 16 are displayed in completely unlimited corresponding to get out of the way the moment on doorway 12 with door 10 for movement Open position when curtain 14 preceding limb 18, Fig. 2 is displayed in and completely closes and stop that the moment on doorway 12 is corresponding with door 10 Closed position when curtain preceding limb 18.Fig. 1,2 and 13 illustrates the example of the curtain 14 in normal condition.

The beneficial aspects of some examples of door 10 are included for guiding and keeping along track 16 in course of normal operation The device of the lateral edges 19 of curtain 14 and for single repacking operation (if lateral edges 19 from track 16 disengaging if) process The separation of both devices of middle guide edge 19 or independent feature.It is this during normal operating and repacking operation The separation of curtain-guide allows each in the two guides to be individually exclusively used in a purpose, without mutually damage Evil.

Under normal operation, for the lateral holding of curtain and the mobile guiding of curtain, the door 10 of some examples includes one The elevated hold button of row or protuberance 40, they are spaced apart far away and are attached generally along the lateral edges 19 of curtain. In some instances, button 40 faces out projection and with approximately spherical profiled surface from curtain 14 each.In some examples In son, the row hold button 40 is moved in and passage 46 in guide rail 16 spaced inward from edge bead 48.Normal Under operational scenario, at two inner surfaces adjacent with each face of curtain 14 of track 16, maintaining item or main retainer 34 will Button 40 is maintained in passage 46, so that curtain keeps in a lateral direction tensioning.In some instances, main retainer 34 is rubbed by low Wipe material to make, such as ultra-high molecular weight polyethylene (UHMW).If blast or barrier provide sufficiently large power on curtain 14, Button 40 will depart from (for example, removed from track 16) to prevent from damaging door 10 from passage 46.In some instances, track At least one of 16 two legs or wall (for example, facing to the opposed walls in contrary two faces of curtain 14) are designed to bent outward Bent (for example, being bent away from curtain 14 by deflection 118), to allow button 40 to depart from from passage 46.

In some instances, edge bead 48 is used in the case where the hold button 40 of curtain is removed from track 16 It is pulled outwardly the lateral edges 19 of curtain.In some instances, edge bead 48 substantially extends the whole length of curtain 14.In some examples In, edge bead 48 has the continuous cross section profile thicker than curtain 14.The example of the continuous cross section profile of pearl includes circular, oval Shape, rectangle or other shape of cross sections.In some instances, after departing from (for example, button 40 is removed from track 16), when When curtain 14 is rolled-up, one group of guide rolls 53 above track 16 are arranged at by the lateral edges 19 of curtain (by engagement edge pearl 48 And abut against edge bead 48 and roll) retract its normal position.When next door is closed and circulated, the unwinding of curtain 14 and button 40 It is properly aligned and reenters in the passage 46 of track 16.

In some instances, in the course of normal operation of door 10 (when button 40 is located in passage 46), edge Pearl 48 (relative to the middle section 76 on doorway 12) be arranged on the outer surface of guide rolls (diameter 50) outside or outside and not Ride on roller 53.Therefore, in some such examples, in course of normal operation, edge bead 48 through roller 53, but The edge 19 of curtain 14 is not guided, any holding function is not provided yet.This reduce and worn and torn and reduced (for example, eliminate) to pearl 48 lubrication needs.And, in some instances, if external force causes hold button 40 to pull out from passage 46, guide rolls 53 will not force the edge bead 48 of curtain to return in passage 46 by retainer 34.However, when curtain 14 is rolls-up onto curtain supporting construction When on 30, guide rolls 53 interact to reset the lateral edges 19 of curtain 14 with pearl 48 so that, close in next door and be circulated throughout Cheng Zhong, button 40 is properly aligned to drop to behind retainer 34 (for example, in the passage 46 of track 16).In some examples In, the passage 46 of guide rail is designed to the enough spaces of offer makes edge bead 48 fresh few, even if not being eternal, with track 16 have substantial exposure.

In some instances, another key character of door 10 is the abnormal door operation of detection and takes the necessary measures to protect The ability that door is not destroyed.In some instances, when the hold button 40 of door is pulled away from track 16, sensor 120 (the Two sensors) this event can be detected, controller 24 reduces the speed of curtain driver element 26 automatically.For example, by reducing curtain 14 The speed rolled, increase is pulled outwardly the edge 19 (for example, engaging with pearl 48 by guide rolls 53) of curtain and into normal position The possibility put, and reduce the possibility of curtain damage.In some instances, sensor 120 is arranged at the lower section of roller 53 24 At inch.

In some instances, if edge bead 48 is pulled through (for example, depart from) guide rolls towards the center of curtain 14 53, another sensor 64 (first sensor) can detect this event, and controller 24 will be automatically stopped will driver element 26 To prevent from damaging curtain 14.In some instances, sensor 64 is located near guide rolls 53.The exemplary position bag of sensor 64 Include but be not limited only to directly over roller 53, immediately below roller 53, and with roller 53 at sustained height.In some instances, If pearl 48 departs from from guide rolls 53 and driver element 26 is stopped, controller 24 sends maintenance alarm signal.

Some examples of door 10 include one or more in following benefits.In some instances, curtain 14 is included for just Often guiding and holding (for example, button 40) and two different elements for resetting process (for example, pearl 48).In some examples In, the two are different and individually elements allow pearls 48 seldom to contact or discontiguous having with main retainer 34 or roller 53 In the case of play passive effect, so as to reduce or eliminate lubrication, reduce and rub, and greatly reduce abrasion.In some instances, originally Design allows the quantity of the hold button 40 for reducing used, because refitting (refeed) operation is complete by pearl 48 and roller 53 Into.For example, in some known doors of door are reset using button or other protuberances, button is typically spaced very near (for example, being spaced maximum 2 inches) and possibly even contact.By contrast, according to teaching disclosed herein, refitting is using single Only edge bead 48 realizes that in some instances, button 40 is spaced very remote (for example, 4 inches, 12 inches, 2 feet etc.). Rephrase the statement, in some examples disclosed herein, such as 40 approximate 0.5 inches of button is wide, then the distance between button 40 Four times (for example, interval is more than 2 inches) of button width can be more than and at least 48 times of the width of button 40 (for example, are spaced 2 Foot).Used as the result that the space between button 40 is larger, in some instances, curtain 14 has when being rolls-up onto on winding drum Less thickness accumulation and less fold.In addition, the quantity of hold button is reduced also reduces the He of button 40 when door 10 is operated Friction between retainer 34.In some instances, rivet 54 (or similar holding protuberance securing member) is designed to shear pin, For rupturing before tear or other damages are caused to relatively expensive curtain.In some instances, hold button 40 is by with can The mode of replacement is attached to door 10, can realize the replacement of button 40 after door 10 is initially installed.In some instances, guarantor is worked as Hold button 40 reduces automatically from curtain speed after the disengaging of guide rail 16.In some instances, when edge bead 48 is from guide rolls Driver element 26 is automatically stopped to reduce damaging the possibility of curtain 14 during 53 disengaging.In some instances, in turn-up process Guide rolls 53 are pulled outwardly edge bead 48 makes it enter correctly into when next door closes circulation beginning to position hold button 40 In the passage 46 of track.

Sometimes fork truck 20 or other materials haulage equipment may strike curtain 14, or when curtain 14 is accidental switched off in its path Barrier on when may clash into.In order to prevent this shock from damaging curtain 14, door 10 includes to recover by allowing curtain 14 Ground departs to respond exemplary disengaging (breakaway) feature 22 of the shock from track 16.As the reaction to clashing into, depart from Curtain 14 is discharged into disengaged position by feature 22, and wherein curtain 14 at least partly departs from from track 16.The exemplary of disengaged position is being schemed Show in 3,4 and 14.According to the seriousness clashed into, in disengaged position, curtain 14 can be at that situation, such as Fig. 3 and 14 can be recovered It is shown, or curtain 14 can be at irrecoverable situation, as shown in Figure 4.Therefore, in some instances, depart from feature 22 to provide The disengaging of two levels.

For the disengaging of the first level after gentle and moderate shock, such as Fig. 3 shown in 7,8 and 14, passes through Simply door 10 is driven into Fig. 1, the open position in 12,15 and 16, departing from feature 22 allows the auto-returned of curtain 14 normally to grasp Make (return normal condition from the disengaged position that can recover situation).For the second level after hard impacts departs from, than As what is illustrated in Fig. 4,9 and 10, made normal door operation fail to avoid the jam of door by controller 24, until the energy of door 10 It is enough to be keeped in repair manually and/or with a certain particular form electric operating.In some instances, manual AD 10 is included curtain 14 Be moved out of it is partially manual be moved back to track 16a, in 16b, so as to curtain 14 is returned into normal shape from the disengaged position of irrecoverable situation State.

In illustrative example, driver element 26 (for example, electro-motor, air motor, Rodless cylinder etc.) is in controller 24 Order under between the opening and closing position of curtain 14 drive curtain 14, while the weight of curtain be suspended on doorway 12 help make curtain 14 Keep tensioning.When door 10 is opened, curtain 14 is stored in the top area 28 including the curtain supporting construction 30 of a certain type.Curtain The example of support structure 30 includes but is not limited only to electronic rotatable drum, helical orbit, the hanger rail that curtain 14 winds around it Road, vertical rail, horizontal rail, warp rail, inclined plane and their various combination.

Track 16 helps that curtain 14 is supported and guided across doorway 12.In addition, track 16 provides the disengaging with the combination of curtain 14 Feature 22.Depart from feature 22 to provide, in some instances, curtain 14 includes main protuberance 32, for the disengaging of first level For main protuberance 32 engage (Fig. 5-12) with main retainer 34.(Fig. 4 and 9) and/or it is for the disengaging of the second level Curtain 14 (Figure 14-16) is guided during repacking operation, the second protuberance 36 is by the second retainer or the side of alignment guide 38 To being limited in track 16.In some instances, main protuberance 32 include along track 16 main retainer 34 slide described in Multiple buttons 40 spaced apart.In illustrative example, main retainer 34 is included by two separate elongated pearls 42 of gap 44.When In normal operating process button 40 along main retainer 34 move when, main retainer 34 helps for button 40 to be maintained at track 16 inner passage 46 is interior and helps guide the movement of curtain.

In some instances, the second protuberance 36 of curtain is the elongated pearl of the alignment guide 38 for moving through track 16 48.In illustrative example, alignment guide 38 is installed to support 49 and including two rollers 53, and each roller 53 has works as Door 10 is slightly rolled or adjacent to the external diameter 50 of the second protuberance 36 when opening and closing against the second protuberance 36.In some examples In, roller 53 has the inclined axle in face relative to curtain 14, as shown in Figure 5.In other examples, the axle of roller is perpendicular to curtain 14.In some instances, the second protuberance 36 is that edge part 52 is ultrasonically welded, combines or is otherwise connected to curtain 14 The integral part of piece part 55.In illustrative example, main protuberance 32 is the form of button, and rivet 54 is by two button halfbodies 40a is connected together with 40b, while edge part 52 and piece part are sandwiched between button halfbody 40a and 40b.In some examples In, rivet 54 or alternative securing member have limited intensity, for use as before other more expensive door parts may be damaged Shear pin rupturing, can easily replacing or " most Weak link portion ".Some examples of button 40 include but are not limited only to 24/ Nylon Cap w/Burr, Matte Black, YKK Part No. Y88B119A01Y；With 24/Nylon Cap, Mattre Black, YKK Part No. M77B119A01Y；Both of which is provided by the YKK Inc. of Georgia's Marietta.

Gentle and moderate shock, such as Fig. 3, shown in 7 and 8, can manufacture and be enough to for main protuberance 32 to be forced through seam The curtain tension force that gap 44 is pulled out from passage 46.Even if main protuberance 32 is more than gap 44, but it is flexible due to some door parts Property, such as the side wall (please noting the track deflection 118 in Fig. 7) of main retainer 34, main protuberance 32, and/or track 16 applies The curtain tension force of the first power 56 still is able to pull main protuberance 32 to pass through gap 44.In some instances, once main protuberance 32 pass through gap 44, curtain tension force to apply the second power 58 (being equal to or more than zero) for reducing, pull the second protuberance 36 to lead to it Gap 44 is crossed, as shown in Figure 8.

In the case where be enough to the gentle and moderate shock that main protuberance 32 is removed into the first length range, in such as Fig. 3,8 and 14 Shown, due to the presence of alignment guide 38, the second protuberance 36 is kept by the laterally limiting track 16 near door, is such as schemed Shown in 5,7 and 14.In some instances, in order to reduce (for example, eliminate) abrasion and rub, in course of normal operation, second Protuberance 36 is slightly separated with alignment guide 38, as shown in Fig. 5 and 13.Track 16 is restricted in the second protuberance 36 In the case of interior, door 10 can return normal operating using repacking operation.In some instances, repacking operation includes opening door 10, alignment guide 38 is led back to curtain 14 in curtain supporting construction 30 using the second protuberance 36, the main protuberance 32 being moved out of Realign with track 16.Driver element 26 continues to open door 10, until preceding limb 18 is increased to the upper end 60 of main retainer Top, as shown in Figure 12 and 15.When on the here height of curtain 14, the refitting opening 62 directly over main retainer 34 is allowed The preceding limb 18 of curtain is easy to slide back into its correct position in passage 46.Subsequently reduce curtain 14 make main protuberance 32 to It is attached to next time in passage 46, so as to main protuberance 32 is returned in the restriction of main retainer 34.

Figure 13-16 schematically illustrates exemplary repacking operation.Figure 13 is displayed in the door 10 in course of normal operation, wherein Curtain 14 is in normal condition.In course of normal operation, main protuberance 32 is kept and is guided by main retainer 34, the second protuberance 36 and alignment guide 38 substantially play passive effect.In course of normal operation, the preceding limb 18 of curtain it is maximum (for example, Normally) move in the restriction of acceleration and speed (First Speed).

Figure 14 shows that curtain 14 is moved to the disengaged position that can recover situation.In illustrative example, disengaged position refer to Few some buttons 40 are forced out from track 16, can be recovered situation and be referred to that roller 53 still makes pearl 48 by laterally limiting in track (guiding piece for example, is aligned in 16 laterally limiting).By errant 16 of being forced, force to the wrong side of main retainer 34 by The curtain stress of the manufacture of button 40 forces pearl 48 to lean against on roller 53, as shown in Figure 14.De-orbit the pressing of 16 (Figure 12) through 44 Button 40 helps protect curtain 14 not damage.In some instances, in order to further avoid damaging, curtain/edge part sensor 120 (second sensor) is installed in the lower section of upper end 60 of main retainer for detecting that curtain 14 is moved to disengaged position, even being in During gentle disengaging.In some instances, sensor 120 is mounted at about 24 inches of the lower section of roller 53.In response to from Sensor 120, represent depart from signal 122 (Fig. 1), controller 24 limit or deceleration curtain preceding limb 18 to reduce Speed (second speed), the speed of the reduction is far smaller than the normal speed of normal operating (First Speed).In some instances, When there is gentle the disengaging, being only arranged at the preceding limb 18 (for example, towards the bottom of door 10) of door 10 button 40 nearby can Can have been removed from.In the present case, it is arranged at the sensor 120 at (towards the top on doorway 12) near alignment guide 38 Door 10 is enabled during the major part that door is moved with normal speed closing, until door 10, have been removed from that Part is detected by a sensor, and at this moment speed is lowered.By this way, door 10 is damaged danger but still with relative to reduce The speed that fast speed is opened is repositioned.

After the position illustrated from Figure 14 removes, exemplary repacking operation starts, wherein the quilt of preceding limb 18 of curtain The position illustrated in Figure 15 is moved upward to the speed for reducing.When the position that the preceding limb 18 of curtain is illustrated from Figure 14 raises During the position illustrated in Figure 15, roller 53 engage with pearl 48 by curtain 14 lead back in curtain supporting construction 30 or in (as shown in Fig. 1 Shown in meaning property).

Once curtain 14 reaches the height illustrated in Figure 15, the refitting opening 62 positioned at the top of main retainer 34 is allowed before curtain Guide margin edge 18 is easy to slip back to its correct position in passage 46, as shown in Figure 16.Subsequently reducing curtain 14 makes main protuberance 32 move back downwards by passage 46, and so as to main protuberance 32 is returned in the restriction of main retainer 34, it is normal that curtain 14 returns its State.In some instances, as curtain 14 returns to its normal condition, pearl 48 slightly is spaced apart to reduce abrasion from roller 53 again And friction.Therefore, in some instances, the protuberance 36 of alignment guide 38 and second rises during repacking operation and actively makees With, but they do not play active role in course of normal operation.

Main protuberance 32 may be removed serious shock the second length more than the first length range from main retainer 34 Scope, this also makes the second protuberance 36 remove from alignment guide 38, shown in such as Fig. 4,9 and 10.In these cases, pass through Electromechanically driving gate 10 is opened or closed and attempted the preceding limb 18 of curtain by refitting opening 62 to make driver element 26 Auto-returned may make the serious jam of curtain 14 in track 16 and/or in curtain supporting construction 30.This jam be difficult release and May permanent damages door 10.Therefore, some examples of controller 24 constrain or forbid normal door operation, until the second protrusion Portion 36 manually or is otherwise repositioned to be correctly aligned with alignment guide 38.

In order to detect whether hard impacts curtain 14 is placed in the disengaged position of irrecoverable situation, some example bags of door 10 Curtain/edge part sensor 64 (first sensor) is included, it is close to sensing curtain in track 16, especially right with the sensing of curtain 14 Position in the region of quasi- guiding piece 38.Although the sensor 64 of illustrative example is shown as the center closer to curtain 14, In some examples, sensor 64 be located in the center approximately the same distance away from curtain 14 (for example, alignment guide 38 just under Side).In some instances, exist when sensor 64 detects the edge part 52 that is correctly positioned near alignment guide 38 When, sensor 64 is in first state (for example, the pent signal 66 of one group of electrical contact of expression), when sensor 64 is not detected To edge part 52 during presence near alignment guide 38, sensor 64 (for example, represents that electrical contact is opened in the second state Signal 66).Some examples of sensor 120,64 include but are not limited only to, photoelectric eye and electro-mechanical limit switches.Pass The more specific example of sensor 120,64 includes the Schneider Electric of Illinois Palatine (Telemecanique) the Part No. XUVR0303PANL2 V shape photoelectric sensors for providing, and Ohio Twinsburg OBT15-R2-E2 types, the background of Part No. 225916 suppression sensor that Pepperl and Fuchs are provided.In some examples In, second sensor 120 is arranged on first sensor 64 and causes sensor 120,64 to distinguish recoverable disengaging, no below Recoverable disengaging and normal condition.

In response to representing signal 66 of the sensor 64 in first state, controller 24 allows normal door operation.Sensor 64 in first state when, curtain 14 is likely to be at normal condition or is likely to be at the disengaged position that can recover situation.No matter which Mode, controller 24 all allows door 10 to open.Therefore, in some instances, sensor 64 is ignored, ignores curtain 14 from normal shape State moves to the disengaged position that can recover situation or it is not responded.

In response to representing signal 66 of the sensor 64 in the second state, controller 24 determines that curtain 14 is in irrecoverable feelings The disengaged position of shape.In this case, the operation of door 10 is forbidden or constrained to controller 24.For example, in some instances, control Device 24 failure door 10 it is Electromechanically operated until curtain 14 is returned manually its normal condition or can extremely recover the disengaged position of situation.

Although the design of curtain 14, edge part 52, protuberance 32,36 and retainer 34,38 and material behavior may change, But some examples of curtain 14 include the compliance sheet material of vinyl or polyurethane.Term " curtain " refers to any component, material sheet material And sheet material, its pliability be enough to can be extensive in the case where the component, material sheet material and sheet material do not suffer from huge permanent damage Depart from its guide rail again.Some examples of curtain 14 include the component of multiple sheet materials.In some instances, it is hard due to nylon Degree and durability, main protuberance 32 is made up of nylon.In some instances, main protuberance 32 than main retainer 34 more firmly more resistant to With so as to the main retainer 34 damaged easily is replaced than a series of main protuberances 32 damaged.In some instances, main holding Device 34 is made up of UHMW (ultra-high molecular weight polyethylene), due to the material it is low with the coefficient of friction of nylon and other materials.One In a little examples, the second protuberance 36 is made up of urethanes, due to its durability and pliability at low temperature.At some In example, the main protuberance of protuberance 32 to the second 36 causes the second protuberance 36 when door 10 is opened to be easy to winding firmly, and And relatively hard main protuberance 32 has minimum dimensional distortion, to keep the constant pullout forces by gap 44.

In the example that main protuberance 32 includes multiple protuberances (for example, button 40) spaced apart, between protuberance Interval allows curtain 14 to be more compactly wound on itself.And, including many of the slip of main retainer 34 along substantial linear The main protuberance 32 of individual protuberance spaced apart forms contact point on the main protuberance 32 for operating and being moved with door 10 68 (Fig. 6 and 11), and approximately fixed contact line 70 (Figure 11) is formed on main retainer 34.Along straight on main retainer 34 Broadly and the abrasion that has been uniformly dispersed on relatively soft main retainer 34, and contact point 68 is concentrated in linear contact lay On relatively hard, durable main protuberance 32.

The second protuberance 36 be have it is adjacent with roller 53 and when and be in contact with it move closer to line 72 (Figure 11) Elongated pearl (for example, pearl 48) example in, the abrasion along relatively soft pearl 48 is divided broadly and equably by along the line 72 Dissipate, for example, the contact point 74 on roller 53 is concentrated in relatively hard, durable alignment guide 38.Therefore, the second protuberance 36 abrasions strategically balanced between them longer than alignment guide 38.Equally, main retainer 34 is longer than main protuberance 32 There is provided similar benefit.

Although the physical orientation of each door part may be different with relative position, in some instances, alignment guide 38 Positioned at the top of main retainer 34, and the middle section 76 on doorway 12 away from main protuberance 32 than away from the second protuberance 36 closer to.This Main protuberance 32 is allowed to depart from and the second protuberance 36 is necessarily as main protuberance 32 departs from together.In some instances, exist When (Fig. 1) in an open position than it is in the closed position when (Fig. 2) sensor 64 closer to preceding limb 18, to allow part to beat The curtain 14 opened is disengaged to that situation can be recovered, without stumbling on sensor 64.The separation of protuberance 32,36 and retainer 34,38 Open and relative positioning is helped distinguish between and can recover situation and irrecoverable situation.More specifically, in some instances, alignment guidance Part 38 is not only vertically biased and Horizontal offset relative to main retainer 34, and alignment guide 38 is higher than main retainer 34.At some In example, as shown in Figure 12, when the preceding limb 18 of curtain is in an open position, main protuberance 32 is spaced with main retainer 34 Open, so as in the passage 46 for allowing curtain 14 itself return trajectory 16.

Figure 17 is to illustrate the feedback signal 66 based on from sensor 64,120, the exemplary status of curtain determined by 122 Truth table 1700.As shown in the example of Figure 17, when signal 66 is in (tripped) state of shock (for example, signal 66=is true) When, and when sensor 64 is not detected by presence of the edge part 52 near alignment guide 38, curtain 14 can be confirmed as place In the disengaged position related to irrecoverable situation, regardless of whether the state of secondary signal 122 is any, and (for example, secondary signal may It is true or false).However, in some instances, (untripped) state (for example, signal 66=is not clashed into when signal 66 is in It is false) when, the state of curtain 14 is determined based on signal 122.Specifically, as illustrated, when signal 122 is in correct with edge part 52 During non-crash situation (for example, signal 122=is false) of the existence correlation being positioned in track 16, curtain 14 is determined being in just Normal state.In some instances, when signal 122 is in crash situation (for example, signal 122=is true), curtain 14 is identified just In the disengaged position (it is assumed that signal 66 be false) related to situation can be recovered.According to truth table 1700, in some instances, often Signal 122 is all knocked when the preceding limb 18 of curtain 14 rises to 120 top of second sensor, even if in edge part 52 just When really being located in track 16, this causes the incorrect instruction of disengaged position.Therefore, in some such examples, controller The position (for example, the rotation by additional sensor or by counting driver element 26) of 24 monitoring preceding limbs 18, and work as Preceding limb ignores signal 122 when being located at 120 top of sensor.In some instances, speed of the door 10 when opening is configured It is to slow down when door 10 reaches fully open position, no matter whether curtain 14 is in disengaged position.Therefore, in some instances, curtain Preceding limb 18 nearby rise to second sensor 120 and be used as the almost full opening of instruction of door 10.In some instances, Controller 24 independently analyzes the signal 66,122 from every side of door 10, for recognizing curtain 14 when in disengaged position Which side is moved out of (or the both sides of curtain 14 are all moved out of).In some instances, additional sensor be used to monitor curtain 14 State.For example, in some instances, multiple sensors 120 are disposed along at the differing heights of track 16 for detecting curtain 14 The height that removed from track of edge.

As elucidated before, in some instances, the protuberance 36 of edge bead 48 or second has thicker than curtain 14 continuous Cross section profile.In some instances, when curtain 14 is wrapped in winding drum above opens door 10, curtain 14 is walked about or is moved in front and back on drum It is dynamic, to avoid forming localized accumulated in the winding process of curtain 14 due to the thickness of edge bead 48.In some this examples, This curtain 14 is likely to result in challenge along moving for winding drum when door 10 is opened and closed.For example, if curtain 14 is along winding drum What is shifted is too remote, then may have excessive load to be applied to curtain 14 from alignment guide 38 or guide rolls 53, and potentially makes Into failure and/or excessive wear in edge bead 48.To the exemplary solution of this problem with regard to Figure 18-22 illustrate and describing .

Figure 18 illustrates be used together with the example door 10 of Fig. 1, the exemplary curtain 14 with reinforcing device 1802.Figure 19 is That a part of enlarged drawing of exemplary curtain 14 in the round A of Figure 18.In illustrative example, multiple reinforcing devices 1802 are along curtain It is attached to curtain 14 at 14 differing heights to extend substantially across curtain 14 between contrary lateral edges 19.In some examples In, extend to edge part 52 in the either side reinforcing device 1802 of curtain 14.In illustrative example, reinforcing device 1802 can be by than curtain 14 The firm any suitable material (for example, glass fibre) of material make, to make curtain 14 when curtain 14 is wrapped on winding drum Edge 19 keeps forcing outside, to reduce the danger that edge bead 48 is pinched in alignment guide 38.However, in some examples In son, the material (for example, glass fibre) of reinforcing device 1802 also has some pliabilities, so as to curtain 14 still can be absorbed from track 16 remove the shock of main protuberance 32 or button 40 without permanent destruction door 10.On the one hand there is this pliability the opposing party's mask There is its rigidity to be possible, in part because when the door is open curtain 14 is wound on itself around winding drum, which has limited The ability that reinforcing device 1802 bends or bends, and expected outward force is provided on the edge 19 of curtain 14.

As shown in Figure 19, it is illustrated that the quilt via the holder 1804 formed by fabric strip 1806 of the reinforcing device 1802 in example It is attached to curtain 14.Particularly, holder 1804 is by following formation：Via any appropriate technology (for example, suture, ultra-sonic welded, With reference to etc.) the upper and lower of each fabric strip 1806 be attached partially into curtain, while reserve may be inserted into the reinforcing device 1802 Gap.In some instances, after reinforcing device 1802 is inserted into holder 1804, every one end of fabric strip 1806 is also coupled to Curtain 14, reinforcing device 1802 is surrounded and fastened in place.

Figure 20-22 is cuing open for the exemplary floating type alignment guidance rack system 2000 of the example door 10 for Fig. 1-4 View.In illustrative example, rack system 2000 includes stationary bracket 2002 (similar to the support 49 of Fig. 5) and can be relative to Sliding support frame 2004 of the stationary bracket 2002 in the plane translation of curtain 14.In addition, in some instances, mounting system 2000 Also comprising by sliding support 2004 relative to stationary bracket 2002 be biased into acquiescence or normal position (Figure 20) one or more Spring 2006.In some instances, rack system 2000 is arranged to make sliding support 2004 relative to stationary bracket 2002 Move inward (Figure 21) towards the middle section 76 on doorway 12.Additionally or alternatively, in some instances, rack system 2000 It is arranged to make sliding support 2004 be displaced outwardly (figure away from the middle section 76 on doorway 12 relative to stationary bracket 2002 22)。

In the illustrative example of Figure 20-22, alignment guide 38 is attached to sliding support 2004 and causes, it is contemplated that second The thickness of protuberance 36 or edge bead 48, when curtain 14 is mobile along winding drum, alignment guide 38 can float or follow curtain 14 Edge 19 motion.In some instances, as shown in Figure 20, when curtain 14 is just in normal operating and/or curtain 14 is centered Be arranged on winding drum on when, the default location of sliding support 2004 causes edge bead 48 to draw through alignment in discontiguous form Guiding element 38, so as to reduce the wear extent in edge bead 48.However, in some such examples, rousing if over curtain 14 Upper winding or unwinding, the edge 19 of curtain starts inwardly to vacillate, then spring 2006 can be shunk so that sliding support 2004 is also inwardly moved It is dynamic, so as to alignment guide 38 can follow the load of edge 19 and reduction from alignment guide 38 in edge bead 48, such as Shown in Figure 21.By contrast, in some instances, when the edge 19 of curtain 14 is displaced outwardly, spring 2006 is expansible so that Sliding support 2004 is also displaced outwardly so as to make alignment guide 38 follow edge bead 48 again, as shown in Figure 22.

Specifically, Figure 24 is shown using the illustrative methods 2400 of example door 10.The method frame illustrated in Figure 24 Figure is necessarily carried out by arbitrary particular order order.In some instances, one or more actions for illustrating in Figure 24 can be saved Slightly, implement simultaneously with other square steps, and/or implement in different order.The illustrative methods originate in step 2402, at this In step, illustrative sensors interface 2304 receives the signal of the disengaged position of the curtain 14 for representing door 10 (for example, via sensor 64,120).In step 2404, exemplary analysis device 2306 determines whether curtain 14 is moved into disengaged position.In some examples In, curtain 14 can be moved to the disengaged position related to recovering situation or irrecoverable situation.In some instances, can recover Situation expelled from main retainer 34 corresponding to main protuberance 32 or remove and the second protuberance 36 keep be aligned guiding piece 38 Limit.For example, the arrow 84 of Fig. 3 and the arrow 132 of Figure 14 represent curtain 14 and are just being moved to the disengaging related to recovering situation State (for example, by putting on the shock of power on curtain 14, causing to be enough to pull out main protuberance 32 from main retainer 34). In some instances, irrecoverable situation is corresponded to, in addition to main protuberance 32 is removed from main retainer 34, the second protuberance 36 are expelled in laterally limiting from alignment guide 38 or are removed.For example, Fig. 4 arrow 88 represent curtain 14 be just moved to The related disengaged position of irrecoverable situation (for example, by put on it is on curtain 14, cause to be enough to main protuberance 32 from main guarantor The shock of the power that holder 34 is pulled out and pulls out the second protuberance 36 from alignment guide 38).The base of exemplary analysis device 2306 Determine whether curtain 14 has been shifted to recover or not in the signal from first sensor 64 and/or second sensor 120 The disengaged position of situation can be recovered.If analyzer 2306 determines that (in step 2404) curtain 14 has not moved into disengaged position (that is, curtain is held in normal condition), then illustrative methods return to step 2402, continue to monitor the disengaged position that represents curtain 14 Signal 66,122.If exemplary analysis device 2306 determines that curtain 14 is moved into disengaged position, illustrative methods continue into Row step 2406.

In step 2406, exemplary analysis device 2306 determine curtain 14 whether in it is related to situation can be recovered (or with can not Recover situation related) disengaged position.In some instances, exemplary analysis device 2306, based on from first sensor 64 , detect the second protuberance 36 by signal (for example, the signal of Fig. 1 of the laterally limiting middle removal from alignment guide 38 66), determine that curtain 14 in the disengaged position related to irrecoverable situation (for example, examine by the representative sensor 64 of arrow 112 of Fig. 9 Measure the disengaged position that curtain 14 moves to irrecoverable situation).In some instances, exemplary analysis device 2306, based on from Second sensor 120, the edge 19 that detects curtain 14 be displaced to the outside of track 16 (for example, when main protuberance 32 is by from main guarantor Holder 34 remove when) signal (for example, the signal 122 of Fig. 1), be simultaneously from first sensor 64 signal 66 represent second dash forward Go out portion 36 to be still positioned at behind alignment guide 38 to determine that curtain 14 is in the disengaged position related to recovering situation.

If exemplary analysis device 2306 determines that curtain is moved into that the disengaged position (step 2406) of situation can be recovered, Method continues executing with step 2408, and in this step, example controller 24 performs repacking operation.The repacking operation of step 2408 Illustrative embodiments will illustrate with reference to Figure 20 and describe.If exemplary analysis device 2306 determines (in step 2406) curtain 14 It is not moved to that the disengaged position (that is, curtain 14 is moved into the disengaged position of irrecoverable situation) of situation can be recovered, then side Method continues executing with step 2410, and in this step, example controller 24 implements expendable curtain operation.Step 2410 is not The illustrative embodiments of recoverable curtain operation will be illustrated with reference to Figure 21 and described.In step 2412, exemplary analysis device 2306 determine whether to continue to monitor curtain 14.If exemplary analysis device 2306 determines to continue to monitor curtain 14, method return to step 2402.If exemplary analysis device 2306 determines do not continue monitoring curtain 14, the illustrative methods of Figure 24 terminate.

Figure 25 show for perform repacking operation, corresponding to Figure 24 illustrative methods 2400 the step of 240 show Example property method.The method and step illustrated in Figure 25 is necessarily carried out with arbitrary specific sequential order.In some instances, Figure 25 In one or more in the method and step that illustrates can be omitted and other square steps are performed, and/or in different order simultaneously Perform.The illustrative methods originate in step 2502, and in this step, exemplary driver cell controller 2302 reduces curtain 14 Speed.For example, when curtain 14 is in normal condition, in course of normal operation, curtain 14 is by with normal (complete) speed driving (example Such as, represented by the arrow 160 of Figure 13).By contrast, (for example, in the feelings recovered for detecting curtain 14 during repacking operation After shape, curtain 14 is driven (for example, to represent that the arrow is than Figure 13's by the arrow 164 of Figure 14 with (slowing down) speed for reducing Arrow 160 is short).In these examples, the speed of curtain 14 being reduced causes the mistake in the main protuberance 32 of refitting as described below Preferably control can be realized in journey.In step 2504, exemplary driver cell controller 2302 is increased on curtain 14 substantially complete Full open position.For example, exemplary driver cell controller 230 electromechanically raises curtain 14 (for example, such as the arrow 104 of Fig. 3 Represent with the arrow 136 of Figure 14), until the preceding limb 18 of curtain 14 reaches the top of upper end 60 of main retainer 34.In step 2506, rise with curtain 14 to realign main protuberance, alignment guide 38 (for example, projects curtain 14 by engagement second Portion 36) it is directed in curtain supporting construction 30.In the present case, by being increased on curtain above the upper end 60 of main retainer 34 (step 2504), while curtain 14 is directed in curtain supporting construction 30, the main protuberance 32 on curtain 14 can leave main retainer 34 Upper end 60, and be brought back into behind main retainer 34 alignment (for example, subsequently when curtain 14 is reduced, as passed through Figure 15 and 16 What arrow 138,140 was represented, the alignment in track 16).In step 2508, exemplary driver cell controller 2302 is extensive by curtain 14 Normal operating state (for example, including with normal speed operation) is answered, now the illustrative methods of Figure 25 terminate.

The illustrative methods of the step of Figure 26 illustrates illustrative methods 2400 for performing Figure 24 2410.The side illustrated in Figure 26 Method step is necessarily carried out with arbitrary specific sequential order.In some instances, in the method and step for illustrating in Figure 26 It is individual or multiple omit and other square steps are performed, and/or performed in different order simultaneously.This illustrative methods originates in Step 2602, in this step exemplary driver cell controller 2302 stop door 10 operation (for example, forbid curtain 14 to move, Such as represented by the mark 168 of Fig. 4).Stop movement by making curtain 14 by this way, can avoid and/or mitigate to curtain 14 And/or the huge damage of door 10.Yet with serious situation of the curtain 14 in the disengaged position of irrecoverable situation, repacking operation It is (as described above with reference to Figure 20) possible unhelpful, it may be necessary to which that curtain 14 is returned into manually normal condition.Therefore, in step 2604, exemplary operator interface 2308 produces maintenance alarm signal.By this way, attendant can learn the disengaging of curtain 14 The irrecoverable situation of state, so as to, the response for performing appropriate (for example keeps in repair manually or reposition the curtain 14 of door 10, such as Fig. 4 What arrow 108 was represented).

In step 2606, exemplary driver cell controller 2302 determines whether to wait curtain to be repositioned onto normal shape State.If exemplary driver cell controller 2302 determines do not wait that curtain is repositioned, the illustrative methods of Figure 26 terminate. If to wait curtain to be repositioned onto normal condition however, exemplary driver cell controller 2302 determines, method is proceeded to Step 2608, in this step exemplary operator interface 2308 determine curtain 14 whether be repositioned onto normal condition. In some instances, exemplary operator interface 2308, the feedback that the attendant based on manual AD 10 provides is determining When curtain 14 has been relocated, and this represents that normal operating can continue.If exemplary operator interface 2308 determines curtain 14 are not also repositioned onto normal condition, then method return to step 2606.If exemplary operator interface 2308 determines curtain 14 have been repositioned to normal condition, then method proceeds to step 2610, in this step exemplary driver cell controller 2302 make curtain return to normal operating state, and at this moment the illustrative methods of Figure 26 terminate.
