In addition, core supporting member 9 is accommodated in cramp bar 21 in the cramp bar incorporating section 51 in little space, and makes cramp bar 21 contact and directly support with following portion 46, so can prevent rocking of core 7, carries out the on-off action of curtain plate 2 swimmingly.And, because the cramp bar 21 of core supporting member 9 is bearing in side portion 2b on the certain position via following portion 46, so, improve the tightness of curtain plate type roller-blind door 1 even curtain plate 2 is subjected to high wind also can be prevented the big deflection of side portion 2b or curl.
And then, cramp bar 21 external diameters with roller 22 are littler than the external diameter of core 7, and be a lateral deviation heart setting of mind-set guiding groove 26 from core 7, so can make cramp bar 21 and side portion 2b near and when restriction moves forward and backward, roller 22 is contacted reliably with a side roll of guiding groove 26.
The curtain plate type roller-blind door 1 that below constitutes like that, utilize the rotating of coiler drum 5, can be by the smooth and easy on-off action that the unwinding action realizes that batches that carries out by curtain plate 2 of advance and retreat action structure, and, by the formation of grounding parts 11 and airtight holding member 32 etc., the tightness in the time of can improving curtain plate 2 and close.And, when curtain plate 2 opens and closes, curtain plate 2 descend and make grounding parts 11 from above during with the powerful butt of butt thing, grounding parts 11 at first bears the butt load by buffer unit 17 via rack earth 16, bear by flexible core 13 then, under the big situation of load, the elastic deflection shock absorbing thereby flexible core 13 makes progress.
And under the situation of continuation effect butt load, flexible core 13 surpasses the curtain plate deflection of butt buffer space L along with the decline of curtain plate 2, with counterweight core 7a butt, makes upwards action of this counterweight core 7a with lifting.Thus, abutting part 11 is kept out of the way action via the top that butt buffer space L upwards dodges the counterweight core 7a that is made of rigid element, so can prevent damage of butt thing and butt thing etc.
And, continue more strongly and make under the situation of flexible core 13 and the counterweight core 7a big core butt tilting action that descends at a slant about core 7 carries out at butt load, at first, the undermost core supporting member 9a of flexible core 13 deviates from from guide rail 3a, then, core 7 also can be deviate from from guide rail 3a via core supporting member 9, avoids excessive butt fault so can utilize this core to deviate from action.And when producing such butt fault, same with prior art, motor 6 reverses by fault detect mechanism, thereby curtain plate 2 is ended to descend and reversed (keeping out of the way) rising.
When having the flexible path A of carrying out above-mentioned effect, also be formed with rigidity path B, described rigidity path B is made of the counterweight core 7a that descends core supporting member 9a most and be bearing in directly over the flexible core 13 with short-range butt buffer space L that is bearing in flexible core 13 both sides, thus, can guarantee the stretching of the lower portion of curtain plate 2, the load of the fore-and-aft direction that causes with respect to high wind etc. can prevent that curtain plate breaks away from and carries out on-off action swimmingly.In addition, owing to make the action of advancing and retreat of core 7 and flexible core 13 by descend most core supporting member 9a, the core supporting member 9 that possess roller 22, so the frictional resistance in the time of alleviating on-off action, and can suppress the slip of curtain plate 2 and realize batching the high speed of unwinding.
In addition, even if counterweight core 7a itself bears big fore-and-aft direction load, this counterweight core 7a does not possess core supporting member class yet but is bearing in the guiding groove 26 via side portion 2b, therefore, counterweight core 7a can not be out of shape, but moves forward and backward via the core supporting width S of side portion 2b and butt buffer space L and cushion load, and, can prevent the big deflection (bulging) of 2 times quadrate parts of curtain plate direction generation forwards, backwards, so can tolerate high wind.
In addition, when curtain plate 2 as described above moves, make grounding parts 11 butt butt things if curtain plate descends, then curtain plate 2 descends under the state that is restricted with butt thing butt, thus the core of adjacency 7 butt and become the oblique state of a certain to the left and right confusedly inclination mutually successively.At this moment, because core supporting member 9 is inserted in the cramp bar incorporating section 51 in little space cramp bar 21 and following portion 46 contiguously, so cramp bar 21 contacts with following portion 46 and makes that the supporting of the 2b of opposite side portion is reliable.Therefore, cramp bar 21 can not produce big dislocation with side portion 2b or separate, so the smooth and easy homing action that carries out curtain plate 2 of energy can also prevent the damage of curtain plate 2.
In addition, core installation portion 2a example as shown is such, utilize a banded sheet material to form core incorporating section 50 of taking in core 7 and the cramp bar incorporating section 51 of taking in core supporting member 9, thus can be efficiently and carry out the operation that base end part 47 and terminal part 49 engage with respect to curtain plate 2 at low cost.
But the formation method of following portion 45 and cramp bar incorporating section 51 is not limited to above-mentioned situation.That is, can be with dividing other sheet material that core incorporating section 50 and cramp bar incorporating section 51 are formed split, between needn't carry out cutting processing can form joint-cutting 52.In addition, can form cramp bar incorporating section 51 with the high sheet material of durability.
Below, with reference to Fig. 8 another embodiment of core supporting construction is described.Omit explanation for structure identical and effect with aforementioned embodiments.The core installation portion 2a of the curtain plate 2 of present embodiment forms core incorporating section 50 and cramp bar incorporating section 51 with a sheet material.
That is, following portion 45, the sheet material that equates with the whole width of curtain plate 2 for length, after afore-mentioned similarly engages base end part 47, engagement end portion 49, and constitute core incorporating section 50 continuously.Thus, can in core incorporating section 50, take in core 7 and core supporting member 9.
Under this state, shown in the dotted line 53 of Fig. 8, like that, following portion 46 parts of the cramp bar 21 residing cramp bar incorporating sections 51 of core supporting member 9 are pushed, utilize heat-sealing or bonding agent etc. to join to integratedly on the side portion 2b.Thus, the following portion 46 of cramp bar incorporating section 51 forms and aforementioned same ladders with respect to the following portion 45 of core incorporating section 50, supports under the state that can move in the inside of restriction core supporting member 9.In addition, with above-mentioned dotted line 53 similarly, terminal part 49 sides also shown in dotted line 54 like that by after cramp bar 21 places join on the curtain plate 2, can further narrow cramp bar incorporating section 51 and make core supporting member 9 more reliable with respect to the supporting of side portion 2b.
In addition, the joint-cutting 52 that forms between core incorporating section 50 and the cramp bar incorporating section 51 makes and carries out as the pushing easily of part of following portion 46, can form simply and can not produce fold in bag portion.And then, can also carry out the plug of core 7 and core supporting member 9 and can not damage a bag portion via joint-cutting 52.
Therefore, for distortion or damaged core supporting member 9, as long as remove the fixing of mounting screw 27 by the operation opposite with assembling sequence, can extract and dismantle via joint-cutting 52, core 7 etc. needn't be pulled down, upkeep operations such as the repairing of core supporting member class or replacing can be carried out simply.
