And, it is provided with the grounding parts 12 thin plate 2 being loaded downward as heavy hammer part, this grounding parts in the lower end of thin plate 2 12 drop under the closed mode of lowest part in thin plate 2, keep airtight along flat ground or floor etc. (hereinafter referred to as floor) Property ground be grounded.This grounding parts 12 is as shown in Fig. 2 by bag-shaped the connecing the weight 12a of transversely built-in iron pipe etc. The both ends of turning back of ground thin plate 12b, and carry out pasting before and after the lower end of thin plate 2 constituting in the state of overlapping.And, connecing In ground thin plate 12b, clamp sponge, the buffer unit 12c of elastomeric material composition and weight 12a between, and, weight 12a's Form spatial portion between bottom and ground connection thin plate 12b.Thus, as shown in the chain-dotted line of Fig. 2, when grounding parts 12 drop to During lower, can prevent weight 12a from directly abutting with floor, and ground connection thin plate 12b can be made closely to be grounded along floor To keep air-tightness.

Thin plate guide part 11, as shown in Fig. 2～Fig. 5, forms groove 13, along the vertical direction at this on the face inwardly of pillar 3 The embedded outer guide 14 being formed U-shaped section in groove 13, the end inwardly of paired side wall 14a before and after fixing.And And, in outer guide 14 inner orbit 16 with the top inner orbit 17 that the top of this inner orbit 16 is connected in the way of assembling and disassembling It is fitted together to and installed.In addition, outer guide 14, inner orbit 16 and top inner orbit 17 are by the flexibility with wearability and regulation Synthetic resin material formed.

As shown in Figure 4, Figure 5, inner orbit 16, in top view, the separation that arranges along the vertical direction in rail part The left and right sides of wall 19, is provided with engaging guide 21 inwardly, this engaging guide 21 and the guide protrusions 10 being attached on thin plate 2 Engaged in the way of carrying out lifting carriage.And, outer guide 14 forms in thin plate direction of extension tool The resilient integral support portion 22 for being installed.

Engaging guide 21 is paired from the both sides of partition wall 19 hook-shaped end head projecting inwardly by having Guide wall 23 is formed.Guide wall 23,23 is formed with and between the hook portion being formed at end head, the lifting of thin plate 2 is guided Sheet groove 23a, and, it is formed between root side and partition wall 19 and connect with sheet groove 23a and so that lifting carriage can be carried out Mode house projecting slot 23b of guide protrusions 10.

Projecting slot 23b of diagram, is formed parallel to hook portion groove width and the guide protrusions 10 of sheet groove 23a.Shown in Fig. 4 Being commonly installed under attitude of inner orbit 16, thin plate 2 is located at the left and right of projecting slot 23b of engaging guide 21 in guide protrusions 10 In the state of centre, lifting carriage is carried out with the state being restricted of extracting inward.

And, contact with people when thin plate 2 is in lifting, high wind etc. and when causing the load by fore-and-aft direction, thin plate 2 Two ends are stretched inwardly, and guide protrusions 10 tend to extracting from sheet groove 23a.Now, because guide protrusions 10 pass through a pair in front and back The hook-type of guide wall 23 and make to extract and be restricted, accordingly it is possible to prevent thin plate gets loose and can carry out the lifting guiding of thin plate 2.

Integral support portion 22 is formed by both sides perisporium projecting outwardly 24,24 before and after partition wall 19 and its.Here week The outer end of wall 24,24 formed opposite to each other before and after the end head of hook cross section between be formed with insertion mounting pin 26 cotter way 27.

According to this structure, in the state mounting pin 26 being set with spiral helicine spring 28 being housed in integral support portion 22 Under, the end head of mounting pin 26 can be made to project from cotter way 27.End head insertion the mounting pin 26 projecting from this cotter way 27 In the installing hole 29 of the diapire 14c being located in outer guide 14, the detachable retainer 30 of latch etc. is installed with this, right Excessive slip inwards is any limitation as.

It has been set with the mounting pin 26 of above-mentioned spring 28, according to the clipping room of the spaced up regulation of upper and lower in outer guide 14 It is housed in integral support portion 22 every the quantity of the multiple installing holes 29 wearing, each mounting pin 26 is inserted corresponding outer guide 14 Each installing hole 29.

According to this structure, as shown in figure 4, inner orbit 16 is installed in the state of being inserted in outer guide 14, by each bullet The elastic force outwardly of spring 28 is resiliently urged on the diapire 14c of outer guide 14, and engaging guide 21 passes through guide protrusions 10 Thin plate 2 is flexibly stretched along thin plate direction of extension outwardly makes it be supported.

The thin plate guide part 11 constituting as described above, when thin plate 2 is subject to the direction (fore-and-aft direction) orthogonal with thin plate face Load when, as shown in figure 5, inner orbit 16 passes through the pulling capacity that thin plate 2 and guide protrusions 10 are subject to direction inwardly.Now interior Track 16 can be resisted spring 28 and flexibly slide along direction inwardly in outer guide 14, therefore can be to drawing direction Power enters row buffering.And, the guide wall 23,23 of now deflection deformation and partition wall 19 flexibly return, accordingly it is possible to prevent The breakage of thin plate guide part 11.

Then, with reference to Fig. 2, Fig. 3, top inner orbit 17 is illustrated.This top inner orbit 17 is assembled and disassembled in outer guide 14 It is connected with the top of inner orbit 16 freely.And, the top of top inner orbit 17 integratedly projecting inwardly be in The plate retainer 31 that horn shape extends.This thin plate retainer 31 can be with 32 points of the retainer of the top both sides being arranged on grounding parts 12 Do not abut.By screwing up nut on the bolt of insertion before and after the lap of the lower end of above-mentioned thin plate 2 and ground connection thin plate 12b, Thus each retainer 32 is arranged on the top both sides of grounding parts 12.

In said structure, thin plate rolling screen door 1, wind Spin Control being carried out to motor 7 in usual opening and closing pattern Thin plate 2 makes the upper limit position that grounding parts 12 rise to highest point be set to, in fig. 2 above-mentioned retainer 32 indicated by the solid line from Thin plate retainer 31 leaves downward and at the position at retainer interval of 20 millimeter stops vertical motion.On the other hand, When producing the surface that the attachment such as misoperation or frost described later is thickly attached to thin plate 2 when thin plate 2 winds, thin plate 2 meeting Exceedingly it is wound up on sheet reeling 5 or makes winding diameter to become big, cross above-mentioned upper limit position sometimes and carry out vertical motion.? In the case of this, the situation that thin plate retainer 31 abuts and thin plate is risen to more than abutted position with retainer 32 is any limitation as, Therefore, it can be any limitation as preventing grounding parts 12 to be exceedingly wound up in sheet cassette 4 by abutting rising to this.

And, the thin plate rolling screen door 1 of embodiment is provided with controlling organization, for carrying out abutting in above-mentioned such thin plate 2 When rising being limited and stopping, eliminating the overload of motor 7 and the on-off action problem of thin plate 2 and keep interim upper limit Put.This keeps the controlling organization of interim upper limit position, so that thin plate 2 is abutted when above-mentioned retainer 32 is abutted with thin plate retainer 31 During stopping, controlling organization is detected or based on load motor load being detected with abutting by the rotation based on pulse detection Lotus detection controlling organization etc., to detect the rotation of motor 7.According to detection signal now, control unit makes motor 7 stop, thereafter Inverted and so that thin plate 2 is extracted out and decline, so that the retainer 32 being in abutting state is stopped and held at from thin plate retainer 31 Leave the interim upper limit position of the above-mentioned thin plate 2 of 20 millimeter downward.

Thus, thin plate rolling screen door 1 can lenitively rolled sheet 2 slightly so that thin plate 2 will not be with inadequate stopping appearance State is fixed on abutting stop position, in this case, can be stopped and held at the next period smoothly decline possess interim Upper limit position, maintains the holding state that ensuing decline possesses.

And then, keep above-mentioned interim upper limit position controlling organization, when in the lower end of grounding parts 12 from thin plate retainer 31 Or the bottom of sheet cassette 4 is downward in the range of the renewal of interim upper limit position of substantially 300 millimeter, on thin plate 2 winding When overload in motor 7 when rising, its overload can be avoided to keep the holding state declining.

That is, when thin plate rolling screen door 1 is opened and closed at low temperature for a long time, in the frost of the Surface Creation of thin plate 2, thickness from Top sequentially increases ground downward and is adhered to, and, thin plate guide part 11 similarly generates and adheres to frost.In this shape Under state, when making thin plate 2 vertical motion, sheet reeling 5 is increased because of frost due to the thickness of thin plate 2, therefore in winding diameter sequentially It is wound in the state of becoming greatly.For this reason, being not up to the setting rotation number (example of the sheet reeling 5 being set by lifting travel amount As 4,5 turn left the right side), even if rotation number ratio its few (for example, about 4 rotations), thin plate 2 can also be crossed upper limit position and make rising Action retainer 32 is abutted with thin plate retainer 31.

And, by this rise restriction grounding parts 12 can be prevented to be involved in sheet cassette 4, on the other hand, motor 7 due to Positive rotation is hindered thus motor load increases, and becomes rotation halted state.

Therefore, when such state of affairs produces in the range of the renewal of interim upper limit position, thin plate rolling screen door 1 is passed through above-mentioned The renewal of interim upper limit position controls makes motor 7 invert, and so that thin plate 2 is extracted out and declines, so that the lower end of grounding parts 12 is for example being existed Stop after declining substantially 20 millimeter, so that load is released, can swimmingly enter next period down maneuver.

In addition, when thin plate rolling screen door 1 makes thin plate 2 in decline in the more new range position below of interim upper limit position During stopping, detecting that controlling organization etc. is switched to rotating forward the rotation of sheet reeling 5 from reversion by load, so that thin plate 2 is risen to Upper limit position.And, when thin plate 2 stops in rising, it is judged as abutting with people or thing, so that thin plate 2 is stopped simultaneously in its position Report to the police.

And then, because thin plate rolling screen door 1 possesses usual opening and closing pattern and possesses defrosting action pattern following detailed description of, Therefore, when thin plate 2 is when being opened and closed action the period of setting time, it is switched to defrosting action pattern from usual opening and closing pattern, Enter to exercise the automatic defrosting operation that the frost being attached on thin plate 2 automatically falls.

Then, with reference to Fig. 6～Fig. 8 to the usual opening and closing pattern of thin plate rolling screen door 1, defrosting action pattern and its action appearance State illustrates.First, shown in thin plate rolling screen door 1 chart as shown in Figure 6, in usual opening and closing pattern, referred to by above-mentioned rising (opening instruction) is made so that motor 7 is rotated forward, thus, sheet reeling 5 makes thin plate 2 wind vertical motion, in the thin plate of top inner orbit 17 Retainer 31 will abut with retainer 32 before upper limit position, control sheet reeling 5 rotation so that it is stopped the rotation, make ground connection Portion 12 stops and becomes the standby attitude of decline.Then, motor 7 is made to invert by decline instruction (closing instruction), thus, sheet reeling 5 make thin plate 2 extract decline out from upper limit position and become closed mode.

Now, thin plate 2 is subject to the weight of grounding parts 12 to decline, when grounding parts 12 reach suitable ground connection position with respect to floor When putting, sheet reeling 5 is made to be automatically stopped.And, the guide protrusions 10 at the two ends of thin plate 2 are formed on the pillar 3 of left and right The inner orbit 16 of thin plate guide part 11 guides, and (horizontal) for thin plate 2 width stretching is slided in the state of preventing from relaxing Decline, will come in and go out atretostomia and reach the standby attitude of rising.In above-mentioned usual opening and closing pattern, thin plate rolling screen door 1 by with Identical motor rotation control mechanism in prior art, started gradually to increase from low speed at the rising initial stage of thin plate 2 and decline initial stage Speed, reaches the translational speed of regulation.On the contrary, in the prescribed limit rising end of a period phase and decline end of a period phase, carry out from above-mentioned rule The slow stopping determined translational speed to start little by little to make motor 7 low speed rotation and stop controls, and thus, makes thin plate 2 in upper limit Put or lower position slowly stops.

And, carry out defrost action pattern occasion, by the mode selector switch 9e being arranged on panel 9 from Above-mentioned usual opening and closing pattern switches over, thus, as shown in Figure 6 to 8, automatically defrosted by defrosting action pattern Run.In addition, in the various figures, illustrate a thin plate 2 on carrying out once after on-off action to making defrosting action pattern connect Till time as t1(minute), the setting of this defrosting action pattern stand-by time, for example can be single with 30 minutes to 1 hour The interval of position, in the time range of 24 hours about, unrestricted choice is set.

And, the number of times that oscilaltion action is repeated in the defrosting action pattern in 1 cycle is represented with n, This set point can be set with the number of times of unrestricted choice 1～10 time about.

That is, defrost action pattern, becomes from the manually or automatically pattern of the usual opening and closing pattern as shown in Fig. 6 and Fig. 7 (a) Defrosting action pattern holding state shown in same Fig. 7 (b).Here, the buzzer 9c being used for informing defrosting action pattern is connected, Carry out the first time defrosting action such as Fig. 7 (c) of the action of action pattern that defrosts after the time (3 seconds about) through setting To carry out as the 1st defrosting mode as shown in～Fig. 7 (f).Then, a series of defrostings shown in Fig. 7 (c)～Fig. 7 (f) are moved Make to be set as the 2nd defrosting mode, sequentially carry out 2～n-1 time action.And then, shown in Fig. 8 (k)～Fig. 8 (o) A series of defrosting actions are set as the 3rd defrosting mode, carry out n-th action.

And, when the automatic defrosting of each action pattern based on defrosting action pattern runs and is over, buzzer 9c is broken Open, revert to usual opening and closing pattern.After the standby setting time of the defrosting action pattern through setting, start again at same Defrosting action pattern, a series of automatic defrostings are repeated and run.And, the panel 9 of thin plate rolling screen door 1, to above-mentioned logical Normally opened close pattern and each setting of defrosting action pattern and defrosting action pattern, except the control unit by built-in (not shown) Outside carrying out, msy be also constructed to be set by the PC being connected with panel 9.Thus, in thin plate rolling screen door 1 In the case of being arranged in the refrigerating equipment of the refrigerator etc. running for example in -20 DEG C about of low temperature, can simply and High efficient and reliable ground is the frost removing being attached on thin plate 2.

Then, with reference to Fig. 7, the 1st defrosting mode of defrosting action pattern is illustrated.From the defrosting shown in this Fig. 7 (b) The thin plate 2 that action pattern holding state is begun to ramp up by the first time action of Fig. 7 (c), with the rate of climb of regulation (2.5m/s about) rise 0.5 second afterwards, the defrosting height as shown in Fig. 7 (d), in the lifting travel way of thin plate 2 At h1, vertical motion is stopped.Then, after stopping the time of 0.3 second, start and carry out shown in 0.5 second Fig. 7 (e) Down maneuver.Now when raising and lowering action is carried out with identical speed, same time, by inertia force make down maneuver away from From ratio vertical motion distance, thus, make the extraction quantitative change of thin plate 2 many, such as shown in Fig. 7 (f), so that grounding parts 12 is strongly grounded And the above-mentioned lower position crossing usual opening and closing pattern is collided with floor, down maneuver is made to stop.

In here the 1st defrosting mode, the thin plate 2 turning off state rises to defrosting height h1 and hastily on the way stops Only, waving, bending etc. and produce by the inertia force of the ascent direction of thin plate 2 and the tensioning of above-below direction and lax and fore-and-aft direction Raw vibration, carries out the 1st defrosting to the surface of thin plate 2.And, thin plate 2 with from defrosting height hl drastically decline and again Vibrated carry out the 2nd time defrosting.And then, thin plate 2 abuts (collision) and carries out the 3rd defrosting with grounding parts 12 floor strength.

Above-mentioned 3rd defrosting, the weight 12a of the grounding parts 12 of thin plate 2 passes through to be grounded thin plate 12b and floor collision.Thus, Grounding parts 12 and the bottom of thin plate 2, the ground connection by being vibrated based on strength and big flexure changes is vibrated, can be to firmly attached The frost the thickness of here part is reliably defrosted.

Then, with reference to Fig. 7, Fig. 8, the 2nd defrosting mode of defrosting action pattern is illustrated.From shown in above-mentioned Fig. 7 (f) Grounding parts 12 and floor collision ground connection after state start, in Fig. 7 (g), in the rate of climb with regulation, (2.5m/s is left Right) carry out at the position after the vertical motion of 0.8 second, as Fig. 7 (h) as shown in, thin plate 2 rise to lifting travel on the way in Defrosting height h2 stops.Then, after stopping 0.3 seconds, start the (i) shown down maneuver of Fig. 8 and decline 0.5 second Clock.Thus, as shown in Fig. 8 (j), thin plate 2 jerk, make grounding parts 12 not be maintained at height h3 with ground plate earthing.

In here the 2nd defrosting mode, vertical motion is made to be configured to removing of the position more second highest than the 1st in lifting travel The thin plate 2 of frost level degree h2 jerk, due to being subject to vibrate from above-mentioned 1st time different the 4th of vibration, so, can make to thin plate 2 The frost that surface carries out not falling during last defrosting falls on a large scale.And then, when making thin plate 2 since then as shown in Fig. 8 (j) Drastically decline and jerk so that grounding parts 12 are maintained at height h3 and not with during ground plate earthing, and thin plate 2 is because under grounding parts 12 The inertia of fall action and moment are stretched the 5th that tightening tension given and are vibrated.Thus, thin plate 2 can make attachment Frost is peeled off to front-rear direction, so that it is come off downward, is defrosted with other effect.And, based on this 2nd defrosting mode A series of defrosting actions, arbitrary number of times (2～n-1 time action) can also be carried out from PC side as needed.

Then, with reference to Fig. 8, the 3rd defrosting mode is illustrated.In this Fig. 8 (k), make connecing shown in above-mentioned Fig. 8 (j) The thin plate 2 that ground portion 12 is in the ungrounded state with defrosting height h3 is risen with the rate of climb (2.5m/s about) specifying 0.8 second afterwards, as shown in Fig. 8 (1), stops vertical motion at the defrosting height h4 in the lifting travel way of thin plate 2 Only.In addition, defrosting height h4 in the case is configured to than defrosting height h2 low clearance.Then, 0.3 seconds are stopped Afterwards, start the down maneuver shown in Fig. 8 (m) and carry out 0.5 second, thus, enter to exercise grounding parts 12 and floor low speed ground connection Control (slow stop control), as shown in Fig. 8 (n), make thin plate 2 stop at lower position, make thin plate 2 become closing shape State, action 3 pattern is over.

And, as shown in Fig. 8 (o), buzzer 9c is disconnected, revert to usual opening and closing pattern.Arbitrarily set following After the fixed time, start again at and carry out same defrosting action pattern, carry out a series of automatic defrosting operations.The above-mentioned 3rd In defrosting mode, can be controlled by above-mentioned slow stopping, to thin plate 2 in the way of making sheet reeling 5 not carry out high speed reverse rotation The down maneuver starting from defrosting height h4 carries out Spin Control, so that thin plate 2 is lentamente declined with low speed and stops at Lower position.

Therefore, when sheet reeling 5 being rotated inertia and from great grounding parts 12 decline when inertia force suppressed Thin plate 2 can correctly stop, and make grounding parts 12 will not from lower position downward side produce dislocation.Be additionally, since thin plate 2 because The low speed of sheet reeling 5 moves, downward thus it is possible to become in the state of extracting the deadweight with grounding parts 12 out and stretching stretching, extension The closed mode that lax, the fold of the thin plate 2 producing in above-mentioned defrosting mode are stretched, furthermore, it is possible to by being grounded The contact with floor for the portion 12 is maintained at lower position in the state of holding is airtight, is swimmingly transformed into usual opening and closing pattern.

Then, the use state of the thin plate rolling screen door 1 constituting as described above is illustrated.First, in above-mentioned low temperature Under the thin plate rolling screen door 1 run with usual opening and closing pattern, when on-off action is frequently carried out, the attachment of frost is also few, so, Can be identical with the usual environment of room temperature swimmingly carry out the opening and closing of thin plate 2.On the other hand, when at low ambient temperatures not Using defrosting action pattern in the state of carry out for a long time thin plate 2 opening and closing when, can adhere in the frost of the Surface Creation of thin plate 2 Frost layer afterwards.

Carry out the thin plate 2 of opening operation in the case, in the state of the sheet reeling 5 being rotated forward is attached to frost Wound and make winding diameter become big, can prevent the retainer 32 crossing upper limit position from abutting with thin plate retainer 31 and will connect Ground portion 12 is involved in.And, now, make sheet reeling 5 invert stopping by the load now producing is carried out with detection temporarily, make to stop Moving part 31 leaves from thin plate retainer 32 and thin plate is stopped and held at interim upper limit position, towards the standby appearance of decline of next period State is changed.

It is additionally, since thin plate rolling screen door 1 and there is the automatic defrosting operation function automatically coming off as the frost making to be attached to Defrosting action pattern, thus it is possible to be defrosted according to corresponding with the use state of the low temperature safedeposit of cold preservation, refrigerating chamber etc. The setting of action pattern, automatically switches towards defrosting action pattern from usual opening and closing pattern and carries out defrosting action.Thus, it is possible to save Power energy-conservation, and contribute to the quality management of the keeping thing interior in low temperature safedeposit to keeping.It is additionally, since defrosting dynamic Make possess various defrosting action patterns, so, when thin plate rolling screen door 1 is arranged on refrigerating chamber being run under above-mentioned low temperature etc. Safedeposit in when, so that the frost being attached on thin plate 2 is come off.

I.e., in the case, the above-mentioned defrosting action pattern in embodiment, no matter the 1st defrosting mode, the 2nd defrosting mould Thin plate 2 need not all be opened by formula or the 3rd defrosting mode, by make grounding parts 12 not from floor leave too high Near the top of lower position, every time lifting action is repeated with the short time, thus effectively give vibration being removed Frost.For this reason, the situation that cold air can be flowed out to outside is suppressed, even and if the thin plate rolling screen door 1 of existing pattern Big structural change need not be carried out it is possible to efficiently realize defrosting by succinct and cheap structure.

It is additionally, since each defrosting action pattern except giving vibration moreover it is possible to combine removing as feature in each pattern White action carries out a series of defrosting action, inadequate action will not in each portion of action, furthermore, it is possible to attached to thin plate 2 The part frost is effectively to be defrosted on a large scale.

That is, in the 1st defrosting mode, so that thin plate 2 is declined, make grounding parts 12 and floor collision, to grounding parts 12 and thin plate 2 Bottom give strong vibration, reliably the frost of this part attachment is defrosted.

In the 2nd defrosting mode, keep height h3 due to jerk so that grounding parts 12 not with ground plate earthing, so, lead to Cross grounding parts 12 big down maneuver when inertia, the stretching, extension tightening tension of moment or resilience can be given to thin plate 2 so as to court Up and down and fore-and-aft direction drastically vibrates, therefore, it can to promote the stripping of the frost being attached to and coming off to be defrosted.

In the 3rd defrosting mode, due to making thin plate 2 carry out down maneuver from defrosting height h4, stop controlling by slow Stop at lower position in the same manner as usual opening and closing pattern, therefore, it can make grounding parts 12 be gently grounded (soft landing) And become suitable closed mode.Therefore, even if thin plate rolling screen door 1 is being arranged on operation in a low temperature of such as -20 DEG C about Freezing equipment in the case of it is also possible to be stiffly attached on thin plate 2 generation bulk frost reliably remove.And, Thus, it is possible to swimmingly based on the vertical motion carrying out thin plate 2 by usual opening and closing pattern.

In addition, the defrosting side based on each defrosting action pattern, order and combinations thereof of the defrosting action pattern of embodiment Method, it is achieved that not making thin plate 2, each action equipment in the thin plate rolling screen door 1 shown in the thin plate rolling screen door 1 of illustrated example and Fig. 9 Defrosted in the case of producing inadequate action, but the rolling screen door for the different equipment of white build environment, different modes Device, had better set the defrosting action pattern of adaptation and action pattern respectively and be defrosted.

And, above-mentioned Defrost method in addition to can be using the thin plate rolling screen door 1 of the thin plate 2 that possesses illustrated example, for tool The thin plate rolling screen door 1 having the further embodiments of thin plate 2 with core components shown in Fig. 9 similarly can use.

Then, the thin plate rolling screen door 1 for above-mentioned further embodiments illustrates with reference to Fig. 9, Figure 10.In addition, it is laborsaving Explanation with identical structure and effect in above-mentioned embodiment.This thin plate rolling screen door 1 is from the thin plate roller shutter of above-mentioned embodiment The outer guide 14 of door 1 has pulled down inner orbit 16 and top inner orbit 17.And, by band core components same as the prior art The two ends insertion left and right of multiple cores 33 of having of thin plate 2a outer guide 14, such that it is able to lifting carriage is carried out to core 33 Guiding, carries out the on-off action of thin plate 2a.

Thus, the thin plate rolling screen door 1 of Fig. 9 is under becoming thin plate 2a wound on the above-mentioned upper limit position on sheet reeling 5 Standby attitude drops.And, when making sheet reeling 5 carry out extracting out rotation, thin plate 2a is extracted out, makes the core 33a that lowermost position is put And next core 33 ... sequentially carries out declining in rail groove 14b and slides, become full-shut position.And, by sheet reeling 5 Winding rotation make each core 33 carry out up-slip in outer guide 14, make thin plate 2a wind rise.The core 33 of illustrated example, 33a, with prior art be identically formed as pipe, by being inserted into the core of the core installation site being formed on thin plate 2 Installed in material installation bag 34 and supported.And, at the two ends of core 33,33a, detachably insert and be mounted with handle Roller 36 is rotatably supported on the shaft on the roller shaft 37 of axle head.

Roller 36 is made up of the synthetic resin material with tolerance to cold and wearability, during roller periphery bloats and is formed Between high flexure plane.And then, form the annular groove 36a of groove-like in the central part of roller 36, in this annular groove 36a detachably Insertion has resilient ring 38, so that the outer peripheral face of ring is projected from above-mentioned flexure plane.And, rotatably insert rolling in roller 36 In the state of wheel shaft 37, detachably installed by being arranged on the installed part 39 of the end of this roller shaft 37.Thus, roll The roller periphery of wheel 36 with outer guide 14 directly contact, but will not make ring 38 carry out contact and rotated, so, Ke Yibao Shield roller periphery makes it not contact with the frost being attached in orbital plane.It is additionally, since ring 38 flexibly to abut with attachment frost, because This, can make thin plate 2 on-off action smooth carry out, and, there is the spy that simply can be changed when ring is worn away Levy.
