Description

本発明は、透過部と不透過部を備えたスクリーンを有するロールスクリーンに関する。 The present invention relates to a roll screen having a screen having a transmission part and a non-transmission part.

このような構成のロールスクリーンとしては、特許文献１に示されるものが知られている。これに示されるものは、天井又は壁面に取付けられるバー本体に回転可能に巻取パイプ（巻取パイプ）を取付け、巻取パイプにスクリーンの一端を固定し、スクリーンの他端を巻取パイプから垂下し錘本体で折り返して、バー本体の一方の側部から突出させたスクリーン固定部材に固定している。 As a roll screen having such a configuration, one disclosed in Patent Document 1 is known. As shown in this figure, a winding pipe (winding pipe) is rotatably attached to a bar body attached to a ceiling or a wall, one end of a screen is fixed to the winding pipe, and the other end of the screen is connected to the winding pipe. It is folded down by the hanging weight main body and fixed to a screen fixing member protruding from one side of the bar main body.

巻取パイプを回転させて、スクリーンを巻取パイプに巻取っていくと、スクリーンの上下方向に交互に形成される透過部と不透過部とが順番に巻取られていく。 When the take-up pipe is rotated and the screen is taken up on the take-up pipe, transmissive portions and non-permeable portions that are alternately formed in the vertical direction of the screen are taken up in order.

この巻取パイプにスクリーンの一端を固定するために、巻取パイプの外周の一部にはその長手方向に断面Ｃ字状の座溝が全長に亘って形成され、また、スクリーンの一端に、この座溝に挿入可能であるけれども座溝の開口部から引き抜き不能な平板部材が逢着されている。スクリーンの一端とともにその平板部材を巻取パイプの長手方向の端縁からその座溝に挿入して、スクリーンを座溝における開口部から引き出すことにより巻取パイプの周囲にスクリーンの端部を固定している。 In order to fix one end of the screen to the take-up pipe, a part of the outer periphery of the take-up pipe is formed with a seat groove having a C-shaped cross section in the longitudinal direction, and at one end of the screen, A flat plate member that can be inserted into the seat groove but cannot be pulled out from the opening of the seat groove is attached. The end of the screen is fixed around the take-up pipe by inserting the flat plate member together with one end of the screen into the seat groove from the longitudinal edge of the take-up pipe and pulling the screen out of the opening in the seat groove. ing.

このような従来の構成のロールスクリーンにおいては、巻取パイプからスクリーンを巻解いていき、巻取パイプに巻き取られているスクリーンの巻数が少なくなっていくと、巻取られているスクリーンの透過部を通して巻取パイプの表面が外部に透けて見えてしまう、という問題がある。スクリーンを下限位置まで下降させると、巻取パイプに巻取られているスクリーンは一巻程度になるため、巻取パイプの表面がより目立つことになり、巻取パイプ部分の意匠性が悪いという問題がある。また、巻取パイプと、透過部と不透過部とのピッチとの関係によっては、最初に巻き取られた透過部の上に次の透過部が重なるため、巻取パイプにスクリーンが数巻程度巻き取られていても、巻取パイプの表面が外部に透けてしまう。 In such a conventional roll screen, when the screen is unwound from the take-up pipe and the number of turns of the screen taken up by the take-up pipe decreases, the permeation of the screen being taken up is reduced. There is a problem that the surface of the take-up pipe can be seen through through the part. When the screen is lowered to the lower limit position, the screen wound on the take-up pipe becomes about one turn, so the surface of the take-up pipe becomes more conspicuous and the design of the take-up pipe part is poor. There is. Also, depending on the relationship between the winding pipe and the pitch between the transmission part and the non-transmission part, the next transmission part overlaps the transmission part that was wound first, so the screen has several turns on the winding pipe. Even if it is wound, the surface of the winding pipe is seen through to the outside.

特に、巻取パイプの多くは無着色のアルミ材で構成されることが多く、スクリーンの透過部を介して巻取パイプの表面の金属面が見えると、ロールスクリーン全体のイメージを損ない、意匠性を悪化させるという問題がある。 In particular, many of the winding pipes are often made of non-colored aluminum material, and if the metal surface of the winding pipe surface is visible through the transmission part of the screen, the image of the entire roll screen is damaged, and the design properties There is a problem of worsening.

本発明は、巻取パイプに巻き取られているスクリーンの巻数が少なくなった状態においても、巻取パイプの表面が透けて見えることが防止されたロールスクリーンを提供することをその目的とする。 An object of the present invention is to provide a roll screen in which the surface of the winding pipe is prevented from being seen through even when the number of turns of the screen wound around the winding pipe is reduced.

前述した目的を達成するために、本発明の一態様は、サイドブラケットに巻取パイプを回転可能に支持し、透過部と不透過部とが上下方向に交互に連続して形成されたスクリーンを巻取パイプに巻取り及び巻解き可能に取付けたロールスクリーンにおいて、
巻取パイプに、不透過部を有する捨て巻き部が設けられ、スクリーンが巻取パイプに巻取られるときに、一巻目の透過部全体が、捨て巻き部の不透過部に重複するように巻取られるようにしたことを特徴とする。 In order to achieve the above-described object, according to one aspect of the present invention , there is provided a screen in which a winding pipe is rotatably supported by a side bracket, and a transmissive portion and a non-transmissive portion are alternately and continuously formed in the vertical direction. In the roll screen attached to the winding pipe so that it can be wound and unwound,
When the winding pipe is provided with a discard winding portion having an impermeable portion and the screen is wound around the winding pipe, the entire transmission portion of the first volume overlaps with the opaque portion of the discard winding portion. It is characterized by being wound up.

また、スクリーンはスクリーン連結部材によって巻取パイプに取付けられ、スクリーン連結部材を境にスクリーンが捨て巻き部と遮蔽部とになり、スクリーンが巻取パイプに巻取られるときに、遮蔽部の一巻目の透過部全体が、捨て巻き部の不透過部に重複するように巻取られるようにしたことを特徴とする。 The screen is attached to the take-up pipe by the screen connecting member, and the screen becomes a winding portion and a shielding portion with the screen connecting member as a boundary, and when the screen is taken up by the take-up pipe, one turn of the shielding portion. The entire transmission part of the eye is wound so as to overlap the non-transmission part of the discarded winding part.

また、スクリーン連結部材は、スクリーンの透過部と不透過部との境目に設けられるようにしたことを特徴とする。 Further , the screen connecting member is provided at the boundary between the transmissive portion and the non-transmissive portion of the screen.

また、捨て巻き部と遮蔽部とは別体であることを特徴とする。 Further , the discarded winding part and the shielding part are separate bodies.

また、捨て巻き部と遮蔽部の巻始めとが、スクリーンの巻取パイプ取付点から重なり合って、同じ方向に巻き取られることを特徴とする。 Further , the discard winding part and the winding start of the shielding part overlap each other from the winding pipe attachment point of the screen and are wound in the same direction.

また、捨て巻き部の不透過部は、少なくとも一巻目の透過部全体が巻き取られる巻取パイプの表面部分に固定されていることを特徴とする。 Further , the non-permeation portion of the discarded winding portion is fixed to a surface portion of a winding pipe where at least the entire transmission portion of the first roll is wound.

また、捨て巻き部の不透過部は巻取パイプの表面全周にわたって固定されていることを特徴とする。 Further , the non-permeable portion of the discarded winding portion is fixed over the entire circumference of the surface of the winding pipe.

本発明によれば、スクリーンが巻取パイプに巻取られるときに、一巻目の透過部全体が、捨て巻き部の不透過部に重複するように巻取られるようになっているため、巻取パイプにスクリーンが僅かしか巻取られていない状態であってもスクリーンの透過部から巻取パイプの表面が透けて見えることがなく、スクリーンを下限位置まで下降させても巻取パイプ部分の意匠性を良好にすることができる。 According to the present invention, when the screen is wound around the winding pipe, the entire transmission portion of the first volume is wound so as to overlap with the non-permeable portion of the discarded winding portion. Even if the screen is only slightly wound on the take-up pipe, the surface of the take-up pipe is not seen through the screen transmission part. Even if the screen is lowered to the lower limit position, the design of the take-up pipe portion Property can be improved.

スクリーン連結部材をスクリーンの透過部と不透過部との境目に設けることにより、スクリーン連結部材を境として捨て巻き部と遮蔽部とを構成したときに、遮蔽部の透過部が捨て巻き部の不透過部に必ず重複するように巻取ることができる。また、捨て巻き部と遮蔽部とを一体に設けることができるため、簡単に構成することができる。 By providing the screen connecting member at the boundary between the transmission part and the non-transmission part of the screen, when the discard winding part and the shielding part are configured with the screen connection member as a boundary, the transmission part of the shielding part is not covered with the discard winding part. It can wind up so that it may overlap with a permeation | transmission part. Moreover, since the throwing-off part and the shielding part can be provided integrally, it can be configured easily.

また、捨て巻き部と遮蔽部とを別体にすることで、捨て巻き部の長さを自由に設定することができるようになる。 Moreover, the length of the discarded winding part can be freely set by separating the discarded winding part and the shielding part.

また、捨て巻き部と遮蔽部の巻始めとが、スクリーンの巻取パイプ取付点から重なり合って、同じ方向に巻き取られるようにしたことで、スクリーンを巻き取ったときに、捨て巻き部が、必ず遮蔽部の巻始めとスクリーンとの間に配置されるようにすることができる。 In addition, since the winding part of the discarding part and the winding start of the shielding part overlap from the winding pipe attachment point of the screen and are wound in the same direction, when the screen is wound up, It can always be arranged between the winding start of the shielding part and the screen.

少なくとも一巻目の透過部全体が巻き取られる巻取パイプの表面部分に、あるいは巻取パイプの表面全周にわたって、不透過部を固定することにより、透過部と不透過部のピッチに関係なく一巻目の透過部全体が捨て巻き部の不透過部に重複するので、巻取パイプの表面がスクリーンを介して透けて見えることを防止することができる。 Regardless of the pitch of the transmission part and the non-transmission part by fixing the non-transmission part to the surface part of the winding pipe where the entire transmission part of the first roll is wound up or over the entire surface of the winding pipe Since the entire transmission part of the first roll overlaps with the non-transmission part of the discarded winding part, it is possible to prevent the surface of the winding pipe from being seen through the screen.

以下、図面を用いて本発明の実施の形態を説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１に示したように、第１の実施形態にかかるロールスクリーンは、図示していない窓枠や天井等に固定されるセットフレーム１０の両端に設けられたサイドブラケット１２に巻取パイプ１４の両端が回転可能に支持されており、巻取パイプ１４にスクリーン１６が巻取り及び巻解き可能に連結されている。スクリーン１６は巻取パイプ１４から垂下するとともに下部レール１８に巻回されて折り返されて上昇し、図示していない支持部材によってセットフレーム１０及び／又はサイドブラケット１２間に支持される。スクリーン１６は、下部レール１８の自重によりその折り返し部が下方に引っ張られることにより、展張状態を維持している。巻取パイプ１４の回転操作は、サイドブラケット１２の一端に設けられた操作チェーン２０を操作することにより行われ、また、操作チェーン２０の操作を停止すれば、公知のストッパにより巻取パイプ１４はその停止位置を維持可能となる。 As shown in FIG. 1, the roll screen according to the first embodiment has a winding pipe 14 attached to side brackets 12 provided at both ends of a set frame 10 that is fixed to a window frame, a ceiling, etc. (not shown). Both ends are rotatably supported, and a screen 16 is connected to the winding pipe 14 so as to be capable of winding and unwinding. The screen 16 hangs down from the take-up pipe 14, is wound around the lower rail 18, is turned up, and is supported between the set frame 10 and / or the side bracket 12 by a support member (not shown). The screen 16 is maintained in a stretched state by pulling the folded portion downward due to the weight of the lower rail 18. The winding pipe 14 is rotated by operating an operation chain 20 provided at one end of the side bracket 12, and when the operation chain 20 is stopped, the winding pipe 14 is moved by a known stopper. The stop position can be maintained.

スクリーン１６は、光をある程度透過する透過部１６ａと、透過部１６ａに比較して光の透過率が低い不透過部１６ｂとが上下方向に交互に連続して一定周期で形成される。好ましくは、透過部１６ａは透明または半透明の生地からなっており、不透過部１６ｂは遮光生地からなっている。また、好ましくは、透過部１６ａの高さ寸法は、不透過部１６ｂの高さ寸法以下、さらに好ましくは、不透過部１６ｂの高さ寸法よりも小さくなるように設定される。これによって、操作チェーン２０を操作して巻取パイプ１４から垂下するスクリーン１６の長さを前記一定周期の間で変化させて、下部レール１８を折り返されて前後に配置されるスクリーン１６の一方側の不透過部１６ｂが他方側の透過部１６ａに対して覆い重なるようにすると、スクリーン１６全体が不透過状態となり、または、一方側の透過部１６ａと他方側の透過部１６ａとが少なくとも一部重なるようにすると、スクリーン１６の一部を透過状態にすることができる。また、操作チェーン２０を操作して巻取パイプ１４からスクリーン１６を巻取り及び巻解くと、下部レール１８が上下動して、スクリーン１６が全体的に昇降する。 The screen 16 is formed with a transmission portion 16a that transmits light to some extent and a non-transmission portion 16b having a light transmittance lower than that of the transmission portion 16a. Preferably, the transmission portion 16a is made of a transparent or translucent fabric, and the non-transmission portion 16b is made of a light shielding fabric. Preferably, the height dimension of the transmission part 16a is set to be equal to or less than the height dimension of the non-transmission part 16b, more preferably smaller than the height dimension of the non-transmission part 16b. As a result, the length of the screen 16 hanging from the winding pipe 14 by operating the operation chain 20 is changed during the predetermined period, and the lower rail 18 is folded back and one side of the screen 16 arranged at the front and back. If the non-transparent portion 16b covers the other side of the transparent portion 16a, the entire screen 16 becomes non-transparent, or at least part of the one-side transparent portion 16a and the other-side transparent portion 16a is provided. If they overlap, a part of the screen 16 can be made transparent. When the operation chain 20 is operated to wind and unwind the screen 16 from the winding pipe 14, the lower rail 18 moves up and down, and the screen 16 moves up and down as a whole.

図２及び図３に示すように、スクリーン１６の巻取パイプ１４への取付けは、巻取パイプ１４の連結溝１４ａにスクリーン１６に連結されたスクリーン連結部材２２を挿入することにより行われる。 As shown in FIGS. 2 and 3, the screen 16 is attached to the winding pipe 14 by inserting a screen connecting member 22 connected to the screen 16 into the connecting groove 14 a of the winding pipe 14.

巻取パイプ１４の連結溝１４ａは、巻取パイプ１４の円周方向の一部に長手方向全長にわたって形成される開口部１４ａ−１と、巻取パイプ１４の内部に開口部１４ａ−１と連通して開口部１４ａ−１よりも円周方向に広がり長手方向全長にわたって形成される凹部１４ａ−２と、から構成される。 The connection groove 14 a of the winding pipe 14 is communicated with the opening 14 a-1 formed in a part of the winding pipe 14 in the circumferential direction over the entire length in the longitudinal direction and the opening 14 a-1 inside the winding pipe 14. The recess 14a-2 extends in the circumferential direction from the opening 14a-1 and is formed over the entire length in the longitudinal direction.

スクリーン連結部材２２は、スクリーン１６が固着される平板状の固着部２２ａと、固着部２２ａの一端部に形成される横断面凸状の係止部２２ｂとを有する。スクリーン連結部２２全体は凹部１４ａ−２の円周方向の大きさよりも小さく、開口部１４ａ−１の円周方向の大きさよりも大きく形成されている。また、係止部２２ｂは凹部１４ａ−２の径方向寸法よりも若干大きく構成されて開口部１４ａ−１の一方の端部に係止可能となっている。そして、一旦、スクリーン連結部材２２が連結溝１４ａ内に挿入されると、簡単には取り外されないようになっている。 The screen connecting member 22 has a flat plate-like fixing portion 22a to which the screen 16 is fixed, and a locking portion 22b having a convex cross section formed at one end of the fixing portion 22a. The entire screen connecting portion 22 is formed to be smaller than the size in the circumferential direction of the recess 14a-2 and larger than the size in the circumferential direction of the opening 14a-1. Moreover, the latching | locking part 22b is comprised a little larger than the radial direction dimension of the recessed part 14a-2, and can be latched to one edge part of opening part 14a-1. Once the screen connecting member 22 is inserted into the connecting groove 14a, it is not easily removed.

スクリーン１６にスクリーン連結部材２２を連結するのは次のように行われる。すなわち、スクリーン１６を最上端部の不透過部１６ｂとこれに隣り合う透過部１６ａとの境目で折り返し、透過部１６ａと不透過部１６ｂとが重なり合うような状態にする。この場合、折り返し部１６ｅよりも最上端部側が、スクリーンの本来の機能である遮蔽機能とは無関係に巻取パイプ１４に巻き付けられまたは固定される捨て巻き部１６ｃとなり、折り返し部１６ｅよりも反最上端部側がスクリーンの本来の機能である遮蔽機能を果たす遮蔽部１６ｄとなる。捨て巻き部１６ｃは、折り返し部１６ｅよりも最上端部側の不透過部１６ｂを有し、遮蔽部１６ｄは、折り返し部１６ｅより反最上端部側の透過部１６ａ及びこれに連続する不透過部１６ｂ、透過部１６ａ・・・を有する。そして、捨て巻き部１６ｃがスクリーン連結部材２２の固着部２２ａの一方の面に直接当接するとともに、折り返し部１６ｅが係止部２２ｂに近接するように配置して、重なり合った捨て巻き部１６ｃの一部と遮蔽部１６ｄの一部とをステープルや縫製等により固着部２２ａに固着する。 The screen connecting member 22 is connected to the screen 16 as follows. That is, the screen 16 is folded at the boundary between the uppermost opaque portion 16b and the adjacent transparent portion 16a so that the transparent portion 16a and the opaque portion 16b overlap each other. In this case, the uppermost end side from the folded-back portion 16e becomes a discarded winding portion 16c that is wound or fixed around the winding pipe 14 regardless of the shielding function that is the original function of the screen, and is more anti-reverse than the folded-back portion 16e. The upper end side is the shielding portion 16d that performs the shielding function that is the original function of the screen. The discarded winding portion 16c has an opaque portion 16b on the uppermost end side than the folded portion 16e, and the shielding portion 16d has a transparent portion 16a on the side opposite to the uppermost end from the folded portion 16e and an impermeable portion continuous therewith. 16b, transmissive portions 16a... The discarded winding portion 16c directly contacts one surface of the fixing portion 22a of the screen connecting member 22, and the folded portion 16e is disposed so as to be close to the locking portion 22b. The part and a part of the shielding part 16d are fixed to the fixing part 22a by stapling or sewing.

このようにスクリーン１６が連結されたスクリーン連結部材２２を巻取パイプ１４に取付けるには、図２（ａ）及び図３（ａ）に示すように、捨て巻き部１６ｃと遮蔽部１６ｄとが重なり合った状態で、スクリーン連結部材２２の固着部２２ａの自由端部に沿って回り込んで固着部２２ａの他方の面上及び係止部２２ｂ上を通過させた状態とする。その後、図３（ａ）中矢印Ａで示すように、固着部２２ａの自由端部側から連結溝１４ａ内にスクリーン連結部材２２を挿入する。スクリーン連結部材２２を連結溝１４ａに完全に挿入すると、図２（ｂ）及び図３（ｂ）に示すように、固着部２２ａの自由端部が連結溝１４ａ内で巻取パイプ１４の内周面に当接して外径方向への移動が規制され、係止部２２ｂが開口部１４ａ−１の一方の端縁に係止して円周方向への移動が規制される。スクリーン１６の捨て巻き部１６ｃと遮蔽部１６ｄは互いに重なり合った状態で開口部１４ａ−１から外部に同方向に導出され、つまり、捨て巻き部１６ｃの自由端部が遮蔽部１６ｄの巻始めと同じ側に配置され、遮蔽部１６ｄと巻取パイプ１４の間に位置する構成となる。 In order to attach the screen connecting member 22 to which the screen 16 is connected in this way to the take-up pipe 14, as shown in FIGS. 2 (a) and 3 (a), the discarded winding portion 16c and the shielding portion 16d overlap each other. In this state, the screen connecting member 22 is turned around along the free end portion of the fixing portion 22a so as to pass through the other surface of the fixing portion 22a and the locking portion 22b. Thereafter, as shown by an arrow A in FIG. 3A, the screen connecting member 22 is inserted into the connecting groove 14a from the free end side of the fixing portion 22a. When the screen connecting member 22 is completely inserted into the connecting groove 14a, as shown in FIGS. 2 (b) and 3 (b), the free end portion of the adhering portion 22a is within the connecting groove 14a. The movement in the outer diameter direction is restricted by coming into contact with the surface, and the locking portion 22b is locked to one end edge of the opening portion 14a-1 to restrict the movement in the circumferential direction. The discarded winding portion 16c and the shielding portion 16d of the screen 16 are led out in the same direction from the opening 14a-1 in a state where they overlap each other, that is, the free end portion of the discarded winding portion 16c is the same as the winding start of the shielding portion 16d. It becomes a structure arrange | positioned between the shielding part 16d and the winding pipe 14 at the side.

次に、スクリーン１６の巻取り及び巻解きの動作を図４及び図５を参照して説明する。 Next, the operation of winding and unwinding the screen 16 will be described with reference to FIGS.

前後に垂下する操作チェーン２０のうちの一方を引き下げて、巻取パイプ１４が図５中反時計方向に回転するようにすると、図４に示すように巻取パイプ１４にスクリーン１６が巻取られる。この際、捨て巻き部１６ｃの自由端部は遮蔽部１６ｄの巻始めと同じ側に配置されているため、遮蔽部１６ｄの一巻目の最初の透過部１６ａが捨て巻き部１６ｃの不透過部１６ｂに重なり合って同じ方向で巻取パイプ１４に巻取られる。上述のように不透過部１６ｂの高さ寸法は、透過部１６ａの高さ寸法以上となっているため、遮蔽部１６ｄの一巻目の最初の透過部１６ａは、捨て巻き部１６ｃの不透過部１６ｂに完全に重複することとなる。従って、この最初の透過部１６ａを介して巻取パイプ１４の表面が透けて見えることはない。この後、遮蔽部１６ｄをさらに巻取っていくと、巻取られたスクリーン分だけ巻径が少しずつ大きくなる。二巻目以降の透過部１６ａは、捨て巻き部１６ｃの不透過部１６ｂまたはそれ以前の巻目の不透過部１６ｂに重複するために、同様に、巻取パイプ１４の表面が透けて見えることはない。 When one of the operation chains 20 that hangs back and forth is pulled down so that the winding pipe 14 rotates counterclockwise in FIG. 5, the screen 16 is wound around the winding pipe 14 as shown in FIG. . At this time, since the free end portion of the discard winding portion 16c is disposed on the same side as the winding start of the shielding portion 16d, the first transmission portion 16a of the first winding of the shielding portion 16d is the non-transmission portion of the discard winding portion 16c. It is wound around the winding pipe 14 in the same direction so as to overlap with 16b. As described above, since the height of the opaque portion 16b is equal to or greater than the height of the transparent portion 16a, the first transparent portion 16a of the first turn of the shielding portion 16d is not transparent to the discarded winding portion 16c. It will completely overlap the part 16b. Therefore, the surface of the take-up pipe 14 is not seen through the first transmission part 16a. Thereafter, when the shielding portion 16d is further wound, the winding diameter gradually increases by the amount of the wound screen. Since the second and subsequent transmission parts 16a overlap the non-transmission part 16b of the discarded winding part 16c or the previous transmission part 16b, the surface of the take-up pipe 14 can be seen through similarly. There is no.

一方、前後に垂下する操作チェーン２０のうちの他方を引き下げて、巻取パイプ１４が図４中時計方向に回転するようにすると、巻取パイプ１４からスクリーン１６が巻解かれていく。そして、図５に示すように、スクリーン１６が下限位置に達して、遮蔽部１６ｄの巻取パイプ１４への巻付きが数巻、または一巻になった場合でも、遮蔽部１６ｄの透過部１６ａ全体が捨て巻き部１６ｃの不透過部１６ｂに重複しているために、透過部１６ａを介して巻取パイプ１４の表面が透けて見えることはなく、巻取パイプ部分の意匠性を良好にすることができる。 On the other hand, when the other of the operation chains 20 hanging back and forth is pulled down so that the winding pipe 14 rotates in the clockwise direction in FIG. 4, the screen 16 is unwound from the winding pipe 14. As shown in FIG. 5, even when the screen 16 reaches the lower limit position, and the winding of the shielding part 16d around the winding pipe 14 is several turns or one turn, the transmission part 16a of the shielding part 16d. Since the whole overlaps with the impermeable portion 16b of the discarded winding portion 16c, the surface of the winding pipe 14 is not seen through the transmitting portion 16a, and the design of the winding pipe portion is improved. be able to.

巻取パイプは一般に無着色のアルミ材で構成されることが多く、巻取パイプの表面がスクリーンから透けて見える場合、意匠性を向上させるためには金属色が露出しないように着色しなければならないが、この実施形態によれば、そのような着色を不要にすることができる。こうして、ロールスクリーン全体の意匠性を向上させることができる。 In general, the winding pipe is often made of an uncolored aluminum material, and when the surface of the winding pipe can be seen through the screen, it must be colored so that the metal color is not exposed in order to improve the design. However, according to this embodiment, such coloring can be made unnecessary. Thus, the design of the entire roll screen can be improved.

また、遮蔽部１６ｄにおいて、透過部１６ａの上に丁度、不透過部１６ｂが重なるように配慮する必要がないために、透過部１６ａと不透過部１６ｂのピッチと、巻取パイプ１４の径との間の自由度を増加させることができる。 Further, in the shielding portion 16d, it is not necessary to consider that the non-transmissive portion 16b just overlaps the transmissive portion 16a. Therefore, the pitch between the transmissive portion 16a and the non-transmissive portion 16b, the diameter of the winding pipe 14 and the like. The degree of freedom between can be increased.

捨て巻き部１６ｃを遮蔽部１６ｄと一体に構成するために、簡単に構成することができる。不透過部１６ｂが透過部１６ａの高さ寸法以上となるスクリーン１６の本来持つ構成を、捨て巻き部１６ｃの不透過部１６ｂでも、そのまま活かすことができ、捨て巻き部１６ｃの不透過部１６ｂによって、遮蔽部１６ｄの一巻目の透過部１６ａ全体を完全に重複させることができる。遮蔽部１６ｄの一巻目の透過部１６ａが２個以上ある場合であっても、捨て巻き部１６ｃの２個以上の不透過部１６ｂによって、遮蔽部１６ｄの一巻目の透過部１６ａ全体を完全に重複させることができる。 Since the discard winding part 16c is configured integrally with the shielding part 16d, it can be configured simply. The original configuration of the screen 16 in which the non-transmissive portion 16b is equal to or larger than the height of the transmissive portion 16a can be utilized as it is in the non-transmissive portion 16b of the discarded winding portion 16c. The entire first transparent portion 16a of the shielding portion 16d can be completely overlapped. Even when there are two or more transmissive portions 16a of the first turn of the shielding portion 16d, the entire transmissive portion 16a of the first turn of the shielding portion 16d is covered by the two or more non-transmissive portions 16b of the winding portion 16c. Can be completely duplicated.

図６に第２の実施形態を示す。なお、以下において説明する構成以外は第１の実施形態と同様なので、説明を省略する。 FIG. 6 shows a second embodiment. In addition, since it is the same as that of 1st Embodiment except the structure demonstrated below, description is abbreviate | omitted.

この実施形態では、捨て巻き部１６ｃと遮蔽部１６ｄとがそれぞれ別体に構成されており、捨て巻き部１６ｃは例えば遮蔽部１６ｄの不透過部１６ｂの共布で構成されている。また、捨て巻き部１６ｃは巻取パイプ１４の表面全周を覆うことが可能な大きさを有している。 In this embodiment, the discarded winding portion 16c and the shielding portion 16d are configured separately, and the discarded winding portion 16c is configured by, for example, a co-fabrication of the non-transmissive portion 16b of the shielding portion 16d. The discarded winding portion 16 c has a size that can cover the entire surface of the winding pipe 14.

捨て巻き部１６ｃと遮蔽部１６ｄは第１の実施形態と同様のスクリーン連結部材２２によって巻取パイプ１４に取付けられる。捨て巻き部１６ｃと遮蔽部１６ｄは、第１の実施形態と同様の方法でスクリーン連結部材２２の固着部２２ａに固着してもよいが、この例では、遮蔽部１６ｄがスクリーン連結部材２２の固着部２２ａの一方の面に直接当接するように遮蔽部１６ｄと捨て巻き部１６ｃとを重ね合わせるとともに、遮蔽部１６ｄと捨て巻き部１６ｃの端部を係止部２２ｂに近接させて配置して、重なり合った捨て巻き部１６ｃの一部と遮蔽部１６ｄの一部とをステープルや縫製等により固着している。 The discarded winding portion 16c and the shielding portion 16d are attached to the winding pipe 14 by the screen connecting member 22 similar to that of the first embodiment. The discarded winding portion 16c and the shielding portion 16d may be fixed to the fixing portion 22a of the screen connecting member 22 in the same manner as in the first embodiment, but in this example, the shielding portion 16d is fixed to the screen connecting member 22. The shielding portion 16d and the discarded winding portion 16c are overlapped so as to directly contact one surface of the portion 22a, and the end portions of the shielding portion 16d and the discarding winding portion 16c are arranged close to the locking portion 22b, A part of the overlapped winding part 16c and a part of the shielding part 16d are fixed by staple, sewing or the like.

そして、このように連結した遮蔽部１６ｄが、スクリーン連結部材２２の固着部２２ａの自由端部に沿って回り込んで固着部２２ａの他方の面上及び係止部２２ｂ上を通過させた状態にする。捨て巻き部１６ｃは、この例では、固着部２２ａの自由端部で回り込ませずに、そのまま同方向に導出させた状態としている。 Then, the shield part 16d connected in this way wraps around the free end of the fixing part 22a of the screen connecting member 22 and passes through the other surface of the fixing part 22a and the locking part 22b. To do. In this example, the discarded winding portion 16c is not led around at the free end portion of the fixing portion 22a but is led out in the same direction as it is.

図６（ａ）に示すように、上記状態を保ちつつ、固着部２２ａの自由端部側から連結溝１４ａ内にスクリーン連結部材２２を挿入し、図６（ｂ）に示すように、捨て巻き部１６ｃと遮蔽部１６ｄを巻取パイプの円周方向に対して互いに逆方向に開口部１４ａ−１から導出する。そして、捨て巻き部１６ｃは巻取パイプ１４の円周方向ほぼ全周に巻付けて巻取パイプ１４に貼り付ける等の方法で固定する。遮蔽部１６ｄは捨て巻き部１６ｃの巻付け方向とは反対方向から巻取パイプ１４に巻取られることになるが、捨て巻き部１６ｃの不透過部１６ｂが巻取パイプ１４ｂ全周に既に巻付けられているため、一巻目の透過部１６ａは必ず捨て巻き部１６ｃの不透過部１６ｂに重複する。よって、透過部１６ａを介して巻取パイプ１４の表面が透けて見えることはない。 As shown in FIG. 6 (a), the screen connecting member 22 is inserted into the connecting groove 14a from the free end side of the fixing portion 22a while maintaining the above-mentioned state. The part 16c and the shielding part 16d are led out from the opening part 14a-1 in directions opposite to each other with respect to the circumferential direction of the winding pipe. The discarded winding portion 16 c is fixed by a method such as winding around the entire circumference of the winding pipe 14 in the circumferential direction and attaching it to the winding pipe 14. The shielding portion 16d is wound around the winding pipe 14 from the direction opposite to the winding direction of the discard winding portion 16c, but the non-permeable portion 16b of the discard winding portion 16c is already wound around the entire circumference of the winding pipe 14b. Therefore, the transmission part 16a of the first roll always overlaps with the non-transmission part 16b of the discard winding part 16c. Therefore, the surface of the take-up pipe 14 is not seen through the transmission part 16a.

なお、捨て巻き部１６ｃと遮蔽部１６ｄの構成は、上記実施の形態のものに限定されることはなく、一巻目の透過部１６ａ全体が捨て巻き部１６ｃの不透過部１６ｂに重複するように巻取パイプ１４に巻取られるように構成されていればよい。よって、捨て巻き部１６ｃを巻取パイプ１４の一巻目の透過部１６ａと重複する部分のみに固定する構成としてもよい。また、捨て巻き部１６ｃをスクリーン連結部材２２に直接連結する代わりに、巻取パイプ１４に直接貼り付けて固定する構成としてもよい。 The configuration of the discard winding part 16c and the shielding part 16d is not limited to that of the above-described embodiment, and the entire transmission part 16a of the first volume overlaps with the non-transmission part 16b of the discard winding part 16c. What is necessary is just to be comprised so that it may be wound by the winding pipe 14. Therefore, it is good also as a structure which fixes the discard winding part 16c only to the part which overlaps with the permeation | transmission part 16a of the 1st volume of the winding pipe 14. Moreover, it is good also as a structure which affixes and fixes directly to the winding pipe 14, instead of connecting the discard winding part 16c directly to the screen connection member 22. FIG.
