Curtain plate

The application is the U.S. Patent application of entitled " Shutter Slat (curtain plate) " submitted on 2 20th, 2013 Numbers 13/772, the 154 continuous case in part, U.S. Patent Application No. 13/772,154 is claimed to be submitted on 2 20th, 2012 U.S. Provisional Patent Application the 61/600th, 909 equity, the two is all incorporated into herein in entirety by reference.

Technical field

The present invention relates to curtain plate and particularly roll curtain plate, with an improved the tolerances to storm and illegally entered Property.The invention further relates to the curtain plates with compact withdrawal ability.

Background technique

Conventional roller shutter is designed to provide for the safety illegally entered or storm protection.Because it is this protection and Safety may and it is not always required or desired, such as during daytime, when retail shop's enabling is made business or the same day When the good homeowners of gas wish to open the window or appreciate seascape, roller shutter is designed to may be withdrawn into shell, they are stored In shell.In some examples, for the ease of compactly storing, it is designed to resist hurricane and the rigid curtain plate of burglar is necessary Spool can be conformed to.

It is a kind of routine curtain plate be manufactured to by provided between lath loosening it is hinged and conform to spool.Lath can be slided It is engaged at the upper edge of lath and the lower edge of another lath dynamicly.Top edge includes the vertical protrusion for terminating in hook-shaped outline Portion.Lower edge includes first part and second part, and first part and second part cooperation are to limit vertical accommodating member.Top edge Hook-shaped outline allow top edge engage lower edge first part, it may have hook-shaped outline.By the second part of lower edge Lai Top edge is prevented undesirably to be detached from lower edge, the second part of lower edge includes protector, and protector extends downwardly into down The hook-shaped outline at edge slightly lower section, the horizontal orifice being limited between the first part of lower edge and second part.By lower edge First part and second part limit vertical accommodating member depth be similar to top edge vertical protuberance height.Due to The vertical portion of top edge pivots in horizontal orifice and realizes this curtain configuration flexibility.

One result of this configuration is that top edge has significant vertical gap in vertical accommodating member.It is known according to this The curtain of kind configuration has up to each lath quarter inch or even greater gap.With 48 laths and each lath The curtain in quarter inch gap has 12 inches of total void between fully open position and fully closed position.In order to Increase it is this have curtain of the torsionspring as balance element, before curtain must start withdrawal, user must use hand or machinery Ground lifts bottom lath to correct gap total amount.In this curtain, user must promote about 150 pounds 12 inches to connect Close curtain retraction mechanism.The curtain of this configuration does not obtain all benefits such as torsionspring or this balance element of other devices offer Place.

The other result of this configuration is that the hinged lath of known loosening generates noise.During extension and withdrawal, Lath issues squish against each other.In addition, the normal force of winding is enough to cause lath sending audible when disposing roller shutter Squish.

Conventional curtain plate is generally designed to hang from spool or mandrel, and spool or mandrel are contained in shell.When withdrawal curtain When, lath is wrapped around a mandrel.Since lath is not assembled together compactly around spool, it is formed by curtain component shape when retracted At larger-diameter volume and accordingly, there is a need for the larger shell of this volume.This may be it is unbecoming, especially in house In the curtain application used on building.Therefore, it is necessary to a kind of curtain components that can compactly store.

A scheme for compact storage problem includes the articulated section between the concentric boss of collection and adjacent lath, such as In the U.S. of entitled " Shutter Slat with Integrated Boss (curtain plate with integrated boss) " of Miller Described in patent the 6,095,225th.With the lath of this configuration be also slidably engaged to a lath top edge and At the lower edge of another lath.Top edge includes the short vertical protuberance terminated in c shape spiral boss, and lower edge includes C shape channel, c shape channel have the diameter for being sufficient to accommodate top edge.The flexibility of this curtain configuration is the rounding by c shape channel What the cooperation of the rounding outer surface of inner surface and c shape spiral boss was realized.The diameter of top edge is less than the diameter in c shape channel, but It is greater than the width in the aperture limited by c shape channel, prevents top edge from simply dropping out from the c shape channel that lower edge provides.

One of this configuration is the result is that if the expose portion in the c shape channel of lower edge is when applying pressure to articulated section Surrender, lath may be separated undesirably.Because being poor based on relatively small size by c shape channel fixing top edge It is different, roller shutter may result in the damage of any edge and destroy.Such as, if it is assumed that effractor hits curtain, and c shape channel may quilt Positive opening.Even if channel is only slight curving, once gap is formed between top edge and lower edge, it may undesirable land productivity Two laths can be pried open with small effort.

A kind of curtain plate is needed, curtain plate minimizes the roller shutter sky needed for being closed completely configuration winding being made of lath completely Between.A kind of curtain plate is also needed, water is not retained, water may freeze and damage lath.

Fig. 6 shows the partial cross-sectional view intercepted along the line A-A of Fig. 5.Curtain plate 1 is shown and guiding piece 13 and holding Screw 29 combines.Screw 29 is kept to be preferably inserted into the holder 23 of curtain plate 1 for guiding piece 13.Keep the head of screw 29 It is slided from 23 projection of holder and in the vertical guiding piece 13 for being set to 9 end of roller shutter in portion 44.In this illustrated embodiment In, it keeps screw 29 to be not intended to limit hook track 7 and is receiving rotation or pivot in track 8.As shown, in order to make roller shutter most Smallization keeps the diameter on the head 44 of screw 29 to be not larger than the exterior contour for receiving track 8.Because 29 head 44 of screw with The receiving track 8 in the space between the first end 15 of lath 1, a lath 1 can be relative to the hook track 7 of another lath 1 Horizontally slide.Horizontal slippage can partly by between 29 head 44 of screw and the first end 15 of lath 1 space or By the configuration limits of guiding piece 13 and 14.Extension screw (not shown) with extended element can replace the use of screw 29.Prolong Stretch screw extended element it is longer than 29 head 44 of screw and be better adapted for attempt illegally enter during or extreme wind Roller shutter 9 is kept under the conditions of power in guiding piece 13 and 14.The example for extending screw is disclosed in U.S. Patent No. 7,784,522 In.

Fig. 7 is the side view for showing two lath 1a according to the present invention and cooperating with 1b, and Fig. 8 is the receiving of lath 1a The detail view that the hook track 7 of track 8 and lath 1b are cooperated.Fig. 7 and Fig. 8 all shows the engagement when curtain plate is in an open position Lath 1a and 1b.As shown in fig. 7, bottom lath 1b is in a vertical position, that is, the position in curtain such as is being opened, lath 1b's Vertical axis 59 is substantially or entirely aligned with the vertical axis 60 of lath 1b.Very little void space is set between lath.And And bottom lath 1b can be hinged in the clockwise direction.

As shown in figure 8, the receiving track 8 of the hook track 7 of lath 1b and lath 1a are slidably engaged in lath 1a Hinge is formed between 1b.The outer surface 31 of the hook 30 of lath 1b is the hinged antelabium for protruding and resting on lip member 10 On the hinged protection coating 18 of the guard member 11 of surface 16 and lath 1a.The top 33 of the hook 30 of lath 1b also rests on lath In the hinged lip surface 16 of the lip member 10 of 1a.The hook 30 of lath 1b is maintained at hinged sky by the lip member 10 of lath 1a Between in 20.In the space that the hook 30 that the top 25 of the lip member 10 of lath 1a extend into lath 1b limits.The antelabium of lath 1a The top 25 of component 10 is also crimped onto hinged space 20, hook track 7 from the formation of receiving track 8 to lath 1b and lath 1a Hinge provide extra safety.

Guard member 11 protects the interconnecting piece of the hook track 7 of lath 1b and the lip member 10 of lath 1a, prevents lath The hook track 7 of 1b is detached from the receiving track 8 of lath 1a.Guard member 11 also protects the hook track 7 and lath 1a of lath 1b Lip member 10 prevent from being exposed to the power on the side 2 being applied to outside the direction of lath 1a and 1b.In open position, rail is received The supporting part in road 8 is lip member 10.Since the hook track 7 of lath 1b is not carried on the guard member of lath 1a directly On 11, compared with the prior art curtain of the expose portion load-bearing of wherein lower railway, to lath 1a direction outside side 2 and lath The damage of the guard member 11 of 1a is less likely to make the hinged disengaging between lath 1a and 2b.

One design advantage of lip member 10 and guard member 11 is lath 1a and 1b not in the hook of lath 1b Water is retained in the hinge that the receiving track 8 of track 7 and lath 1a are formed.The lip member 10 of lath 1a is at its minimum point from master The intersection horizontal shift of the hook track 7 of body portion 4 and lath 1b.The intersection of the hook track 7 of main part 4 and lath 1b Place is smooth transition.This design allows water neatly to flow from the lip member 10 of lath 1a, without being discharged to lath 1a In the hinge formed with the intersection of 1b.

It is excessively hinged to prevent that lath 1 does not need protrusion.Using lath 1, the plate compared with the prior art of guard member 11 Item thickeies.It is excessively hinged that the thickness of guard member 11 and the shape of lip member 10 prevent lath 1, and does not need in hook Protrusion on component 7.There is no protrusion, there is no the channel for retaining water, water is dripped from lip member 10.Water is such as retained, water may It freezes and damages hinge.

Fig. 9 is the side view for showing the two lath 1c engaged when lath is in the close position and cooperating with 1d.As schemed Show, lath is worked as flush against on the inner surface 32 of the hook 30 of lath 1d in the top 25 of the lip member 10 of lath 1c When in the fully closed position, the main part 4 of lath 1c and 1d form substantially circular arc.Lath in the fully closed position When, this circular arc allows the initial sub-component of the lath 1 of roller shutter 9 to be resisted against with being substantially flush in mandrel 19 and then allow for 1 sub-component of lath is formed around initial sub-component and around the similar circular arc of other sub-components.It will be appreciated by persons skilled in the art that can Advantageously to be closed completely to change lath radian to minimize roller shutter 9 and be in it as the distance between lath and mandrel increase Required gross space when coincidence is set.

When curtain is in the close position, the shape of guard member 11 also makes the total radius of the roller shutter of lath 1 minimum.Such as institute above Statement, guard member 11 is more shorter than prior art lath and thicker, and when lath 1 is in a vertical position, guard member 11 minimum point is higher than the minimum point of lip member 10.As shown in figure 9, as lath 1c and 1d in the close position, lath 1c Guard member 11 distance at 19 center 65 of centrifugal shaft and lath 1d at its 19 center of centrifugal shaft, 65 farthest point hook track 7 The distance at 19 center 65 of centrifugal shaft is approximately uniform at its 19 center of centrifugal shaft, 65 farthest point.This configuration is in closure position in curtain Total radius occupied by each sub-component when setting by minimum around the lath of mandrel 19 makes the total of the roller shutter 9 of lath 1 Radius is minimum.Moreover, the outer surface of protector 11 is formed to be arranged essentially parallel to the curvature of main body, curtain is rolled to reduce Total radius of plate.

In a preferred embodiment, lath is equipped with turn of bilge or recess between hook track and Plank body.Such as in Fig. 3 It is best shown, lath 1 has turn of bilge between main body 4 and hook track 7 at first edge 5.Turn of bilge allows in adjacent panels Hinge between item forms smooth transition.For example, Fig. 7 and Fig. 8 show the hinge in vertical position between lath 1a and 1b. When the hook track 7 of lath 1b is engaged in the receiving track 8 of lath 1a, turn of bilge allows in the outer surface of hook 30 31 and protection Smooth transition is formed between the outer protection coating 17 of component 11.Think that this smooth transition allows water neatly to flow through hinge, and It will not collect and be discharged in hinge.It has also been found that the angle of turn of bilge is more sharp, the effect for reducing water penetration to hinge is better.

In certain strip shaped tectonics, may interfere between main body and hook track there are turn of bilge has been recovered to roller shutter The smallest ability in space needed for full-application position.For example, Figure 10 shows with hook track 7 and receives the lath of track 8 1, hook track 7 and receiving track 8 protrude from the convex curvature top of the main body 4 of lath, that is, prominent from the side 2 outside.Hook The engagement of type track 7 and receiving track 8 forms hinge 62, and hinge 62 protrudes from above the common convex curvature of lath 1, and in phase After formation gap 64 between the main body 4 of the adjacent slat in winding.When curtain is rolled onto withdrawal or fully closed position, these gaps Interfere tight fit.

It was found that prominent (that is, prominent from the side in below Plank body concave curvature by being formed to have lath Receiving track out), the space needed for the roller shutter of retrieving position can be minimum, without damaging between main body and hook track Turn of bilge.With reference to Figure 11 and Figure 12, the alternate embodiment of lath is shown with the receiving track with lip member, lip member Below the concave curvature for protruding from the side in the direction of main body.The guard member of track is received to extend along main body curvature.

As shown in figure 11, lath 100 has main body 104, and main body 104 has first edge 105 and opposite with first edge Second edge 106.Main body 104 includes the curvature 151 with radius of curvature, the side 102 outside convex direction and recessed direction Interior side 103.Hook track 107 is connected to main body 104 at first edge 105 and receives track 108 in second edge Main body is connected at 106.
