【発明の属する技術分野】
本発明は、壁面貼着用の化粧シート繰り出し装置に関するものである。
【０００２】
【従来の技術】
従来、室内の壁面に壁紙等の化粧シートを貼着する場合、作業者がまず貼着箇所の壁面の採寸を行ない、化粧シートを原反ロールから繰り出して糊付けし、採寸した壁面に応じて所定の長さに裁断した後に、壁面に貼着する方法をとっている。また予め糊が塗布されている化粧シートを用いる場合にも、同様に壁面の採寸を行なった後、化粧シートを裁断して貼着する方法を採っている。
【０００３】
【発明が解決しようとする課題】
従来の化粧シートの貼着作業には、次のような問題点がある。即ち、貼着作業前に予め壁面を採寸し、その寸法に応じて化粧シートを裁断しておく必要があるため、実際に化粧シートを壁面に貼着するまでに多くの時間と手間を要し、作業能率が著しく損なわれるという問題点がある。しかも化粧シートは皺が生じやすい上に、壁面の貼着箇所の面積が広い場合には裁断後の化粧シートも大きくなるため、壁面の貼着箇所までの持ち運び、その他に熟練を要し、一人での作業が非常に困難である。
【０００４】
本発明は、このような従来の問題点に鑑み、予め壁面を採寸して化粧シートを裁断しておく必要がなく、原反ロールから化粧シートを引き出して壁面に直接貼着できる壁面貼着用の化粧シート繰り出し装置を提供することを目的とする。
【０００５】
【課題を解決するための手段】
本発明の化粧シート繰り出し装置は、支持枠１１に、化粧シート５の原反ロール９を着脱自在に支持する繰り出し手段１３を備え、該繰り出し手段１３は、前記原反ロール９の巻き芯８にその軸心方向に貫通状に挿通される回転軸２５を備え、前記支持枠１１に、前記回転軸２５の軸心方向の両端側に対応して、該回転軸２５が上側から着脱自在に嵌合する嵌合凹部２６と、その嵌合状態で前記回転軸２５を下側から回転自在に支持するローラー２７とを設けたものである。
【０００６】
また、支持枠１１に、化粧シート５の原反ロール９を着脱自在に支持する繰り出し手段１３と、前記原反ロール９から繰り出された前記化粧シート５の裏面側の糊６用の保護シート７を巻き芯１５に巻き取る巻き取り手段１６と、前記繰り出し手段１３と前記巻き取り手段１６とを連動させる連動手段１７とを備え、前記繰り出し手段１３及び巻き取り手段１６は、前記原反ロール９及び前記保護シート７用の巻き芯８，１５にその軸心方向に貫通状に挿通され且つ前記支持枠１１に着脱及び回転自在に装着される回転軸２５，２８を備え、該回転軸２５，２８に、該回転軸２５，２８と前記巻き芯８，１５との相対回転を防止する回転防止手段３１を設けたものである。
【０００７】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて詳述する。図１〜図１１は本発明の第１の実施形態を例示している。図１において、１は床面、２は天井、３は壁面、４は幅木である。５は糊６付きの壁紙等の化粧シートで、この化粧シート５は図２に示すように、裏面側にその略全面に塗布された生糊等の糊６を保護する保護シート７を有し、貼着前は紙管等の巻き芯８に巻き取った原反ロール９の状態にあり、壁面３への貼着に際して原反ロール９から引き出し、保護シート７を剥がして壁面３に糊６等により貼着するようになっている。
【０００８】
１０は化粧シート繰り出し装置（以下、繰り出し装置という）で、原反ロール９から化粧シート５を引き出して壁面３に貼着する際に、貼着箇所の壁面３の下方近傍で床面１上に置いて使用するためのものであり、図３〜図１１に示すように構成されている。
【０００９】
即ち、繰り出し装置１０は、図３〜図９に示すように、支持枠１１と、この支持枠１１を床面１上で任意の方向に移動自在に支持する複数個のキャスター車輪１２とを備え、支持枠１１に、原反ロール９を着脱自在に支持する繰り出し手段１３と、原反ロール９から繰り出された化粧シート５を壁面３側へと案内する案内手段１４と、繰り出し手段１３に対して案内手段１４と反対側に配置され且つ原反ロール９から繰り出された化粧シート５の糊６用の保護シート７を巻き芯１５に巻き取る巻き取り手段１６と、繰り出し手段１３と巻き取り手段１６とを連動させる連動手段１７とを備えている。
【００１０】
支持枠１１は、左右一対の側板１８と、この一対の側板１８を左右に連結する連結部材１９とを備え、横長状に構成されている。各側板１８は後側に段部２０が形成され、巻き取り手段１６側の高さが低くなっている。また各側板１８には、前後両側に左右方向の内側に屈折する屈折部２１が一体に形成されており、その下端部に連結部材１９がねじ等により固定されている。なお、屈折部２１は、図９に示すように連結部材１９の固定箇所に対応して下端部が左右方向の内側に延出されており、夫々２カ所で連結部材１９がねじ止めされている。連結部材１９は、各側板１８の前後に一対あり、断面Ｌ字状に構成されている。
【００１１】
なお、実施形態では支持枠１１をアルミニウム、ステンレス等、耐食性の金属により構成しているが、例えば合成樹脂等により構成しても良い。また支持枠１１は所定の剛性を有し、原反ロール９、化粧シート５等と干渉しない構造であれば十分である。
【００１２】
キャスター車輪１２は、各連結部材１９の左右両端側で、その下側にねじ、ロックナット等により構成された上下調整手段２２を介して装着されている。なお、図１に仮想線で示すように支持枠１１の左右方向の一端側等の適宜箇所に操作杆２３を取り付けて、作業者が脚立２４等の作業足場上に乗って化粧シート５の貼着作業を行なう場合に、その操作杆２３を操作することにより、作業者が作業足場に乗ったままで繰り出し装置１０を任意の方向に移動させ得るようにしても良い。
【００１３】
繰り出し手段１３は、原反ロール９の巻き芯８に、その軸心方向に着脱自在に挿通された一本の繰り出し回転軸（回転軸）２５と、この繰り出し回転軸２５をその軸心方向の両端側で回転自在に支持するローラー２７とを備えている。繰り出し回転軸２５は、巻き芯８に貫通状に挿通され、その軸心方向の両端側が、支持枠１１の各側板１８に形成された嵌合凹部２６に上側から着脱自在に嵌合されている。嵌合凹部２６は、各側板１８の上縁側に開放する略Ｕ字状に切り欠き形成されている。ローラー２７は、各嵌合凹部２６の下側の前後に一対あり、左右方向の軸心廻りに回転自在に各側板１８の左右方向の内側に固定されており、繰り出し回転軸２５を下側から側板１８と接触しないように支持するようになっている。なお、繰り出し回転軸２５には、原反ロール９を巻き芯８に挿通する際にその挿入方向を間違えないように、例えば化粧シート５の繰り出し方向を示す矢印等の目印がシール等により付されている。
【００１４】
巻き取り手段１６は、繰り出し手段１３の後下方の近傍にあり、保護シート７用の巻き芯１５にその軸心方向に着脱自在に貫通状に挿通された一本の巻き取り回転軸（回転軸）２８と、ローラー３０とを備え、繰り出し手段１３と略同様に、巻き取り回転軸２８が嵌合凹部２９に嵌合され、ローラー３０により支持されている。巻き取り回転軸２８用の嵌合凹部２９及びローラー３０は、図７等に示すように各側板１８の段部２０側に設けられており、巻き取り回転軸２８を繰り出し回転軸２５よりも下側で支持するようになっている。なお、各回転軸２５，２８は全体が中空円筒状に構成されているが、必要部分のみを中空状又は円筒状に構成しても良い。
【００１５】
繰り出し回転軸２５及び巻き取り回転軸２８には、図１０及び図１１に示すように、原反ロール９及び保護シート７用の巻き芯８，１５との相対回転を防止するための回転防止手段３１が設けられている。回転防止手段３１は、長手方向の一端が各回転軸２５，２８の外周に固定された弾性帯状片３２により構成され、この弾性帯状片３２を回転軸２５，２８に巻き付けた状態で巻き芯８，１５に挿入した際に、弾性帯状片３２がその弾性により巻き芯８，１５の内面に圧接して、回転軸２５，２８と巻き芯８，１５との一方側への相対回転を防止するようになっている。
【００１６】
即ち、回転軸２５，２８又は巻き芯８，１５に回転動力が伝わった際に、その回転により弾性帯状片３２が外側に拡がる方向（図１０（ｂ）における回転軸２５，２８のａ矢示方向又は巻き芯８，１５のｂ矢示方向）であれば回転軸２５，２８と巻き芯８，１５との相対回転が防止され、その逆方向であれば相対回転が許容されるようになっている。従って、弾性帯状片３２は、図４に夫々矢示した原反ロール９の巻き芯８及び巻き取り回転軸２８の回転により、外側に拡がるような方向、即ち図４における反時計廻りに各回転軸２５，２８に巻き付けられている。
【００１７】
逆に、回転軸２５，２８及び又は巻き芯８，１５を、弾性帯状片３２が回転軸２５，２８側に巻き付く方向に回転させた場合には、回転軸２５，２８と巻き芯８，１５とが相対回転してその挿脱が容易にできるようになっている。
【００１８】
なお、回転防止手段３１をこのように構成した場合には、回転軸２５，２８と巻き芯８，１５との軸心方向の相対移動も防止することができる。
【００１９】
弾性帯状片３２は、例えば平行四辺形の帯状に形成されたゴム等の弾性体で、巻き芯８，１５に回転軸２５，２８を挿通した際に巻き芯８，１５の軸心方向の略中央に位置するように、短辺の一方側が回転軸２５，２８の外周にねじ６９により固定されている。なお、弾性帯状片３２の外側には、回転軸２５，２８への固定部に対応してゴム等の補強材７０が設けられており、弾性帯状片３２と補強材７０とがねじ６９により共締め状に回転軸２５，２８に固定されている。
【００２０】
また弾性帯状片３２は、回転軸２５，２８を巻き芯８，１５へ挿通する際の入り側の長辺が、固定部から先端側に向かって巻き芯８，１５への挿入方向と反対向きに傾斜する傾斜縁部３３ａとなっており、この傾斜縁部３３ａが螺旋縁となって巻き芯８，１５へと挿入され易くなっている。なお、実施形態では出側の長辺も同様に傾斜縁部３３ｂとしているが、傾斜していなくても良いし、逆向きに傾斜していても良い。また弾性帯状片３２は、回転軸２５，２８に巻き付けたときに、回転軸２５，２８を周方向に一周する長さよりも若干短い程度の長さとなっている。
【００２１】
なお、弾性帯状片３２は、巻き芯８，１５に挿入される部分であれば巻き芯８，１５の軸心方向の中央から偏った位置となるように回転軸２５，２８に設けても良いし、回転軸２５，２８の軸心方向に１又は複数設けても良い。また弾性帯状片３２の巻き芯８，１５の内面に接触する面は、粗面状等、巻き芯８，１５の内面に対する摩擦係数が大きくなるようにしても良い。
【００２２】
連動手段１７は、図３〜図６及び図９に示すように、支持枠１１の側板１８に外側板３４を介して支持されたギヤ伝動機構、ベルト伝動機構等の連動機構１７ａを備え、この連動機構１７ａを介して繰り出し手段１３の繰り出し回転軸２５と巻き取り手段１６の巻き取り回転軸２８とが連動回転するようになっている。
【００２３】
外側板３４は、側板１８と同様に耐食性の金属等により構成され、側板１８の上部側に対応する形状になっている。また外側板３４は、前後両側に左右方向の内側へと屈折する固定部３５を一体に備え、この固定部３５を介して側板１８の屈折部２１にねじ等により着脱自在に固定されており、側板１８との間に左右方向の適宜な隙間が形成されている。なお、側板１８と外側板３４とを一体に形成しても良いし、側板１８で直接連動機構１７ａを支持するようにしても良い。
【００２４】
外側板３４には、繰り出し回転軸２５が同心状且つ着脱自在に連結された繰り出し連動軸（連動軸）３６と、巻き取り回転軸２８が同心状且つ着脱自在に連結された巻き取り連動軸（連動軸）３７と、繰り出し連動軸３６の下側、例えば略真下側で且つ巻き取り連動軸３７の横側、例えば略真横側に配置された中間軸３８とが軸受け等を介して左右方向の軸心廻りに回転自在に支持されている。
【００２５】
各連動軸３６，３７には、図５及び図９に示すように、各回転軸２５，２８側の先端に、径方向の外側に突出する係合突起（係合部）３９が周方向に１又は複数、例えば等間隔に２個形成されている。一方、各回転軸２５，２８には、係合突起３９に対応して先端から切り欠き状に係合凹部（被係合部）４０が形成されており、各回転軸２５，２８を各連動軸３６，３７の先端に遊嵌状に套嵌して連結した際に、回転軸２５，２８と連動軸３６，３７とを連動回転させるべく係合突起３９と係合凹部４０とが係脱自在に係合するようになっている。
【００２６】
繰り出し連動軸３６及び中間軸３８には、外側板３４の内側に大径ギヤ４１及び小径ギヤ４２が設けられており、このギヤ伝動機構により繰り出し連動軸３６と中間軸３８とが連動回転するようになっている。また中間軸３８及び巻き取り連動軸３７には、外側板３４の外側に駆動プーリ４３及び従動プーリ４４が設けられると共に、両プーリ４３，４４に跨って伝動ベルト４５が巻き掛けられており、このベルト伝動機構により中間軸３８と巻き取り連動軸３７とが連動回転するようになっている。
【００２７】
大径ギヤ４１と小径ギヤ４２とのギヤ比は例えば６：１程度、また駆動プーリ４３と従動プーリ４４は略同径になっており、繰り出し回転軸２５側に対して巻き取り回転軸２８側が増速されるように設定されている。駆動プーリ４３及び／又は従動プーリ４４と伝動ベルト４５との間には適宜滑りが発生するようになっており、この滑りにより繰り出し手段１３側の化粧シート５の繰り出し速度と、巻き取り手段１６側の保護シート７の巻き取り速度とが略同一となるようになっている。また駆動プーリ４３と従動プーリ４４との中間には、長孔４６を介して上下調整自在に張力プーリ４７が外側板３４に固定されており、この張力プーリ４７により伝動ベルト４５の張力を調節して駆動プーリ４３及び／又は従動プーリ４４と伝動ベルト４５との滑りの程度を調節できるようになっている。
【００２８】
支持枠１１の連動手段１７と反対側の側板１８には、図３及び図５〜図８に示すように、回転軸２５，２８と連動軸３６，３７との連結を保持するための連結保持手段４８が設けられている。連結保持手段４８は、回転軸２５，２８の上側に近接してその上側への移動を規制するための第１規制部材４９と、回転軸２５，２８の連動軸３６，３７と反対側の端部に近接して回転軸２５，２８の左右方向の外側への移動を規制するための第２規制部材５０とを備えている。なお、各規制部材４９，５０は、回転軸２５，２８に当接して滑るように構成しても良い。
【００２９】
第１規制部材４９は、嵌合凹部２６，２９の上部側近傍で側板１８の左右方向の外側にねじ等の左右方向の枢軸５１により一端が枢支された帯板状の部材で、嵌合凹部２６，２９の上側の開口を前後方向に塞いだ状態で他端がねじ５２等により側板１８に固定されるようになっている。第２規制部材５０は、正面視倒立Ｌ字状の部材で、左右方向の一端が、第１規制部材４９の上端に溶接等により接続され、他端が、第１規制部材４９が嵌合凹部２６，２９の開口を塞いだときに回転軸２５，２８の端部の左右方向の外側に近接するようになっている。なお、第１規制部材４９と第２規制部材５０は一体に形成しても良い。
【００３０】
従って、連結保持手段４８は、第１規制部材４９を枢支する枢軸５１廻りに、回転軸２５，２８の上側及び左右方向の外側への移動を規制する規制位置と、それらを許容する許容位置との間で位置変更自在に構成されており、第１規制部材４９の他端をねじ５２により側板１８に固定することにより規制位置に保持できるようになっている。
【００３１】
案内手段１４は、図４〜図７に示すように、支持枠１１の前部側から前側、即ち壁面３側へと突出する左右一対の支持アーム５４と、この支持アーム５４の先端部に原反ロール９と略平行に且つ軸心廻りに回転自在に支持された案内軸５５とを備えている。支持アーム５４は、その基部側が支持枠１１の側板１８の下端部に外側から当接されると共に蝶ねじ５６等により外側から角度調整自在に固定されている。
【００３２】
支持アーム５４には、基部側から先端側にかけて案内軸５５用の長孔５７が形成されると共に、この長孔５７に案内軸５５を上側から容易に着脱できるように上向きの開口５８が形成されている。開口５８は、一方（連動手段１７側）の支持アーム５４では先端側に、他方の支持アーム５４では基部側に夫々形成されており、化粧シート５の繰り出し等により案内軸５５の両側が両支持アーム５４から同時に外れることがないようになっている。
【００３３】
また外側板３４には、図６に示すように固定部３５の支持アーム５４に対応する位置に上下方向のスリット３５ａが形成されており、支持アーム５４は、図５に仮想線で示すように、このスリット３５ａに嵌合して起立状に折り畳み可能になっている。なお、案内軸５５を取り外したときには、支持アーム５４を支持枠１１から前側に突出しないように折り畳むことも可能である。
【００３４】
案内軸５５は、その両端側が両支持アーム５４の長孔５７に着脱自在に嵌合されると共に、長孔５７から軸心方向に抜けないように両端部にボルト、ナット等の抜け止め部材５５ａが固定されており、長孔５７の方向にその範囲内で移動可能になっている。また案内軸５５は、原反ロール９から繰り出された化粧シート５を壁面３側へと案内する機能の他に、化粧シート５を切断する際に、カッター等の裁断手段を案内するための案内部材としての機能も有している。
【００３５】
上記構成の繰り出し装置１０により壁面３に化粧シート５を貼着する際には、先ず原反ロール９の巻き芯８に繰り出し回転軸２５を、保護シート７用の巻き芯１５に巻き取り回転軸２８を夫々挿通する。このとき、各回転軸２５，２８に弾性帯状片３２を巻き付け、その巻き付け方向と反対廻りに回転軸２５，２８を回転させながら、弾性帯状片３２の傾斜縁部３３ａの固定部から先端側への傾斜方向と、巻き芯８，１５への回転軸２５，２８の挿入方向とが反対になるように挿入していけば、巻き芯８，１５に回転軸２５，２８を容易に挿通することができる。すると、弾性帯状片３２がその弾性により巻き芯８，１５の内部で外側に広がろうとして巻き芯８，１５の内面に圧接するので、回転軸２５，２８と巻き芯８，１５との相対回転を防止することができる。
【００３６】
次に各回転軸２５，２８を支持枠１１に装着する。このとき連結保持手段４８を枢軸５１廻りに許容位置にし、回転軸２５，２８の係合凹部４０側の端部を連動軸３６，３７の先端側に套嵌すると共に、回転軸２５，２８を支持枠１１の側板１８の嵌合凹部２６，２９に上側から嵌合する。すると、連動軸３６，３７の係合突起３９が回転軸２５，２８の係合凹部４０に係合すると共に、側板１８に固定されたローラー２７，３０が回転軸２５，２８を下側から回転自在に支持し、回転軸２５，２８と連動軸３６，３７とが連動回転するようになる。
【００３７】
また回転軸２５，２８を連動軸３６，３７に遊嵌状に套嵌して連結し、回転軸２５，２８側の荷重をローラー２７，３０で受けると共に、回転軸２５，２８の移動をローラー２７，３０及び側板１８で規制するようになっているので、回転軸２５，２８側の加重等が連動軸３６，３７にかかることがなく、連動軸３６，３７、連動機構１７ａ等の破損を防止できる。
【００３８】
各回転軸２５，２８を支持枠１１に装着したら、連結保持手段４８を枢軸５１廻りに規制位置にして、第１規制部材４９の他端をねじ５２により固定する。これにより、回転軸２５，２８と連動軸３６，３７との連結が化粧シート５の繰り出し等によって不用意に外れることがなくなる。
【００３９】
回転軸２５，２８の支持枠１１への装着と前後して、案内手段１４の支持アーム５４の上下方向の角度を蝶ねじ５６の操作により調整し、化粧シート５の切断位置に応じて案内軸５５の上下位置を調整する。壁面３の下端部に幅木４がある場合には、案内軸５５を幅木４の上端側の高さに合わせる。因みに幅木４の幅は、一般的に５ｃｍ、７．５ｃｍ、１０ｃｍである。また幅木４がない場合には、壁面３の下端近傍で案内軸５５が床面１に接触しない程度に調整する。なお、幅木４は化粧シート５の貼着後にその前側から重ねて貼着しても良い。
【００４０】
化粧シート５の実際の貼着に際しては、先ず原反ロール９から化粧シート５の端部を案内軸５５側に引き出し、その化粧シート５から剥がした保護シート７の端部を巻き取り手段１６の巻き芯１５に止める。そして、原反ロール９から案内軸５５の下側を経て化粧シート５を壁面３側に繰り出して行く。
【００４１】
すると原反ロール９と繰り出し回転軸２５とが回転防止手段３１の弾性帯状片３２の作用により連動回転し、その回転動力が連動手段１７を介して巻き取り回転軸２８へと伝達され、巻き取り回転軸２８に套嵌された巻き芯１５が回転防止手段３１の弾性帯状片３２の作用により巻き取り方向に回転する。このため化粧シート５を繰り出していけば、原反ロール９からの化粧シート５の繰り出しに同調して、巻き芯１５に保護シート７を巻き取ることができる。
【００４２】
大径ギヤ４１と小径ギヤ４２とのギヤ比により繰り出し回転軸２５側に対して巻き取り回転軸２８側が増速されるようにし、さらに伝動ベルト４５と駆動プーリ４３及び／又は従動プーリ４４との間に滑りが発生するようにしているので、原反ロール９の径及び巻き取られた保護シート７の径の大小が変化するにもかかわらず、繰り出し手段１３側の化粧シート５の繰り出し速度と、巻き取り手段１６側の保護シート７の巻き取り速度とを略同一に保つことができ、保護シート７を所定の張力状態で巻き取ることができる。従って、化粧シート５の繰り出しに異常な抵抗が加わったり、保護シート７が張力の増加によって破れたりするようなこともなく、化粧シート５の繰り出し及び保護シート７の巻き取りを円滑に行なうことができる。
【００４３】
また化粧シート５の引き上げに伴って案内手段１４の案内軸５５が回転するので、案内軸５５による抵抗も少なく、案内軸５５を壁面３と略平行にしておけば、貼着箇所の壁面３の下側近傍から壁面３に沿って化粧シート５を円滑に案内できる。
【００４４】
化粧シート５の上端が貼着箇所の上端に達すれば、化粧シート５の上端部を貼着箇所の上端に合わせた状態で壁面３に貼着して止める。これで化粧シート５が壁面３に沿って垂れ下がった状態になるので、案内軸５５にカッターをあてがい、案内軸５５に沿ってカッターを移動させながら化粧シート５を幅方向に略一直線状に切断する。そして、裏面側の糊６により化粧シート５を壁面３の貼着部位の全体に貼着する。
【００４５】
この実施形態の繰り出し装置１０は、繰り出し手段１３及び巻き取り手段１６の各回転軸２５，２８と、この各回転軸２５，２８が挿通される各巻き芯８，１５との相対回転を防止する回転防止手段３１を設けているので、化粧シート５の繰り出しによる原反ロール９の回転動力を、連動手段１７を介して巻き取り手段１６側の巻き芯１５に確実に伝達することができ、保護シート７を巻き芯１５に確実に巻き取ることができる。しかも、回転防止手段３１を回転軸２５，２８の外周に固定された弾性帯状片３２により構成しているので、簡単な構成で安価に製造でき、また巻き芯８，１５への回転軸２５，２８の挿通も簡単に行なうことができる。更に回転軸２５，２８と巻き芯８，１５との軸心方向の相対移動も防止することができる。
【００４６】
支持枠１１に、回転軸２５，２８の軸心方向の両端側に対応して、回転軸２５，２８が上側から着脱自在に嵌合する嵌合凹部２６，２９と、その嵌合状態で回転軸２５，２８を下側から回転自在に支持するローラー２７，３０とを設けているので、支持枠１１への回転軸２５，２８の着脱を簡単に行なうことができ、また軸心方向の両端側で回転軸２５，２８を確実に支持することができる。
【００４７】
連動手段１７の各連動軸３６，３７に係合突起３９を設け、各回転軸２５，２８に、連動軸３６，３７と連結した際にその係合突起３９と係脱自在に係合する係合凹部４０を形成し、その係合により回転軸２５，２８と連動軸３６，３７とが連動するように構成しているので、回転軸２５，２８と連動軸３６，３７との連結構造を簡単にでき、容易に着脱することができる。
【００４８】
支持枠１１に、回転軸２５，２８と連動軸３６，３７との連結を保持するための連結保持手段４８を設けているので、回転軸２５，２８と連動軸３６，３７とが簡単に着脱できる連結構造であるにもかかわらず、その連結が化粧シート５の繰り出し等により不用意に外れることがない。しかも、連結保持手段４８を第１規制部材４９及び第２規制部材５０により構成し、回転軸２５，２８の上側及び左右方向の外側への移動を規制するようにしているので、簡単な構成で確実に回転軸２５，２８と連動軸３６，３７との連結を保持することができる。
【００４９】
また案内手段１４を上下調整可能に構成しているので、種々の幅の幅木４に対応できる。更に、外側板３４にスリット３４ａを形成し、案内手段１４の支持アーム５４を起立状に折り畳み可能に構成しているので、繰り出し装置１０の保管、運搬等に際して便利である。
【００５０】
図１２〜図１５は本発明の第２の実施形態を例示する。この実施形態の繰り出し装置１０は、支持枠１１と、この支持枠１１を床面１上で任意の方向に移動自在に支持する複数個のキャスター車輪１２とを備え、支持枠１１に、原反ロール９を着脱自在に支持する繰り出し手段１３と、原反ロール９から繰り出された化粧シート５の糊６用の保護シート７を巻き芯８に巻き取る巻き取り手段１６と、繰り出し手段１３と巻き取り手段１６とを連動させる連動手段１７と、繰り出し手段１３から繰り出された化粧シート５の裁断に際して刃物等の裁断手段を化粧シート５の幅方向に案内する裁断案内手段７２と、壁面３の裁断案内手段７２の上端に対応する高さｘから化粧シート５の貼着部分の下端ｙまでの距離ａに応じて裁断案内手段７２と壁面３とを所定間隔に保持する間隔保持手段７３と、原反ロール９から繰り出された化粧シート５を検尺するための検尺手段７４とを備えている。
【００５１】
なお、この実施形態の繰り出し装置１０は、裁断案内手段７２、間隔保持手段７３、検尺手段７４を設けた点及び案内手段１４を設けていない点を除いて、第１の実施形態と略同様に構成されている。
【００５２】
裁断案内手段７２は、支持枠１１の左右両側板１８間に跨って、その前側の屈折部２１の前後にねじ９０等により共締め状に固定された一対の案内部材７５を備え、この一対の案内部材７５間の隙間によりカッター等の裁断手段を化粧シート５の幅方向に案内するための案内溝７６が構成されている。各案内部材７５は、両側板１８間に対応する長さの断面倒立Ｌ字状の耐食性を有する金属材等であって、側板１８の屈折部２１の圧み分だけの隙間をもって、両者が略同じ高さに略Ｔ字状となるように配置されている。なお、前後の案内部材７５の何れか一方のみにより裁断案内手段７２を構成しても良い。
【００５３】
裁断案内手段７２の各案内部材７５は、化粧シート５が繰り出しに際して干渉しないように、側板１８の上端よりも若干下側に取り付けられている。また側板１８の一方又は両方には、その屈折部２１の裁断案内手段７２の上端から下側に１ｃｍ間隔等の目盛り８９がシール等により設けられており、壁面３の裁断案内手段７２の上端に対応する高さｘから化粧シート５の貼着部分の下端ｙ（例えば幅木４の上端）までの距離ａを計測できるようになっている。
【００５４】
間隔保持手段７３は、支持枠１１に出退自在に取り付けられ且つ先端側が壁面３に当接される一対の当接アーム７７により構成されている。当接アーム７７は、耐食性を有する金属製等の帯板状で、その基部側に形成された取り付け孔７８ａ〜７８ｃに外側から挿通された蝶ねじ７９等により、支持枠１１の側板１８に外側から着脱自在に取り付けられている。なお、連動手段１７側の当接アーム７７は側板１８の外側板３４に取り付けられている。
【００５５】
また取り付け孔７８ａ〜７８ｃ及び蝶ねじ７９は、当接アーム７７の支持枠１１からの突出量、即ち裁断案内手段７２の案内溝７６と壁面３との間隔ｂを調整する間隔調整手段８０を構成している。取り付け孔７８ａ〜７８ｃは、当接アーム７７の長手方向に所定間隔をおいて複数、例えば３個形成されており、それらの中から択一的に選択した取り付け孔７８ａ〜７８ｃに蝶ねじ７９を挿通して当接アーム７７を略水平に支持枠１１に取り付けることにより、その突出量を調整できるようになっている。
【００５６】
壁面３の裁断案内手段７２の上端に対応する位置ｘから化粧シート５の貼着箇所の下端ｙまでの距離ａの応じて間隔調整手段８０の各取り付け孔７８ａ〜７８ｃの何れかを選択するに際して、幅木４の５ｃｍ、７．５ｃｍ、１０ｃｍ等の既定の幅に対応して選択できるように各取り付け孔７８ａ〜７８ｃを形成しておいても良いし、前記距離ａを目盛り８９により計測してその計測値により選択できるように、例えば１ｃｍ間隔等の等間隔に各取り付け孔７８ａ〜７８ｃを形成しておいても良い。後者の場合には当接アーム７７側にも目盛りを設けておくと良い。
【００５７】
なお、間隔調整手段８０は、複数の取り付け孔７８ａ〜７８ｃにより構成する以外にも、段階的又は連続的に異なる突出量で当接アーム７７を支持枠１１に取り付けることができる構造であれば、その構成を適宜変更可能である。例えば取り付け孔７８ａ〜７８ｃに替えて長孔を形成すれば、当接アーム７７の突出量を連続的に変化させることができる。
【００５８】
当接アーム７７は、図１３に実線で示すように支持枠１１から略水平に突出する突出位置と、二点鎖線で示すように側板１８に沿って収納する等、支持枠１１から突出しない退避位置との間で、蝶ねじ７９廻りに出退自在に構成されており、不要なときには退避位置にすることにより邪魔にならないようになっている。
【００５９】
なお、当接アーム７７は、図１３に一点鎖線で示すように、突出位置から退避位置へと水平方向に退避するようにしても良い。この場合、例えば当接アーム７７を水平方向に摺動自在に支持するガイド部材等を設ければ良いし、当接アーム７７をその支持枠１１からの突出量が段階的又は連続的に異なる複数箇所で固定する固定手段を設け、この固定手段とガイド部材とにより間隔調整手段８０を構成しても良い。このように構成する際には、連動手段１７の構成、当接アーム７７の取り付け高さ等を適宜変更してそれらが干渉しないようにすれば良い。なお、当接アーム７７は、退避位置のときに支持枠１１から若干突出していても良いし、起立状、水平状、その他の姿勢に退避するようにしても良い
検尺手段７４は、連動手段１７と反対側の側板１８に設けられており、基部側が左右方向の枢軸８１廻りに回転自在に側板１８に取り付けられた支持アーム８２と、この支持アーム８２の先端側に取り付けられた検尺器８３と、この検尺器８３を原反ロール９側に付勢する付勢手段８４とを備えている。
【００６０】
検尺器８３は、原反ロール９から繰り出された化粧シート５の長さを検尺して表示するためのもので、例えば、原反ロール９の繰り出される前の化粧シート５に当接され且つ化粧シート５の繰り出しに応じて回転する検尺ローラー８５と、この検尺ローラー８５と支持アーム８２との間に配置され且つ検尺ローラー８５の回転数に基づいて化粧シート５の繰り出し量を計測し表示するカウンター８６とを備えている。なお、支持アーム８２は繰り出し手段１３よりも後方で側板１８に枢支されており、検尺ローラー８５が原反ロール９に後上方から当接するようになっている。
【００６１】
付勢手段８４は、支持アーム８２の先端側と側板１８の繰り出し回転軸２５用の嵌合凹部２６の近傍との間に取り付けられた引っ張りばね８７により構成され、適当な力で検尺ローラー８５を原反ロール９側に付勢して、化粧シート５の繰り出しに伴って検尺ローラー８５を確実に回転させると共に、化粧シート５の繰り出しに伴って原反ロール９の径が小さくなっても、図１５に一点鎖線で示すように検尺ローラー８５を原反ロール９に当接させるようになっている。
【００６２】
なお、検尺手段７４の構成、取り付け位置等は、原反ロール９から繰り出した化粧シート５を検尺可能であれば、適宜変更しても良い。検尺ローラー８５は原反ロール９に当接する以外にも、原反ロール９から繰り出された後の化粧シート５に当接するようにしても良い。付勢手段８４も検尺ローラー８５等を原反ロール９側に付勢できれば、板ばね、圧縮ばね等のばね、ゴム、その他のものを使用しても良い。
【００６３】
また検尺手段７４は、使用しないとき、原反ロール９を支持枠１１から着脱するときなどには、図１５に二点鎖線で示すように検尺ローラー８５が原反ロール９から離間する退避位置に退避できるようになっている。因みに、支持アーム８２が二点鎖線で示す位置にある場合には、引っ張りバネ８７が支持アーム８２を原反ロール９と逆向きに付勢するので、ストッパー９１に当接して支持アーム８２を退避位置に保持できるようになっている。
【００６４】
次に、この実施形態の繰り出し装置１０により壁面３に化粧シート５を貼着する際の説明をするが、回転軸２５，２８への巻き芯８，１５の取り付け、連動軸３６，３７への回転軸２５，２８の連結等、第１の実施形態と同様の手順は省略する。
【００６５】
この実施形態では、先ず、壁面３の裁断案内手段７２の上端に対応する高さｘから化粧シート５の貼着部分の下端ｙまでの距離ａに応じて、当接アーム７７の先端を壁面３に当接したときに裁断案内手段７２の案内溝７６と壁面３との間隔ｂが所定間隔になるように、当接アーム７７の支持枠１１からの突出量を調整する。この調整に際しては、間隔調整手段８０の複数の取り付け孔７８ａ〜７８ｃの内の１個を幅木４の幅等に応じて選択し、蝶ねじ７９により当接アーム７７を支持枠１１の側板１８に略水平となるように固定すれば良い。
【００６６】
なお、壁面３の裁断案内手段７２の上端に対応する高さｘから化粧シート５の貼着部分の下端ｙまでの距離ａと、裁断案内手段７２の案内溝７６と壁面３との間隔ｂとが略等しくなるように調整しても良いし、所要の余分をもって化粧シート５を裁断する場合には、後者の間隔ｂが前者の距離ａに対して大きくなるように調整しても良い。
【００６７】
次に、図１２に示すように、間隔保持手段７３の当接アーム７７の先端が壁面３に当接した状態で、化粧シート５を壁面３側へと繰り出していく。このとき第１の実施形態と異なり案内手段１４を介さずに直接上方へと化粧シート５を繰り出していくので、より抵抗が少なく、円滑に化粧シート５を繰り出すことができる。
【００６８】
化粧シート５の上端が壁面３の貼着箇所の上端に達すれば、化粧シート５の上端部を貼着箇所の上端に合わせた状態で壁面３に貼着して仮止めする。これで化粧シート５が壁面３に沿って垂れ下がった状態になるので、裁断案内手段７２の案内溝７６に沿ってカッター等により化粧シート５を裁断する。このときには、壁面３と裁断案内手段７２との間で化粧シート５を略水平にし、裁断案内手段７２の案内溝７６に沿って化粧シート５を裁断すれば、間隔保持手段７３により裁断案内手段７２の案内溝７６と壁面３との間隔ｂが所定間隔に保持されているので、壁面３の貼着箇所に対応して、又は所要の余分をもって化粧シート５を裁断することができる。なお、化粧シート５の糊６面が裁断案内手段７２側になっているので、その糊６により化粧シート５が裁断案内手段７２に軽く接着しその動きが規制されるので、簡単且つ正確に裁断することができる。
【００６９】
このようにして壁面３の貼着箇所に応じて化粧シート５を所定の長さに裁断できる。なお、化粧シート５の長さに余分を持たせるように間隔保持手段７３を設定した場合には、幅木４の上端に合わせて再度化粧シート５を裁断するようにしても良いし、化粧シート５の貼着後にその上から重ねて幅木４を貼着するようにしても良い。
【００７０】
また階段の壁面３、天井２等に化粧シート５を貼着するとき、又は十分な作業スペースが確保できないときなど、図１２に例示するように使用できない場合には、キャスター車輪１２を取り外し、繰り出し装置１０を適当な台上に載置して使用しても良い。この場合には、壁面３の貼着箇所の寸法を予め採寸しておき、原反ロール９から繰り出した化粧シート５を検尺手段７４により検尺して裁断し、その裁断済みの化粧シート５を貼着箇所まで運搬して貼着すれば良い。なお、このように使用した場合にも、巻き取り手段を１６を設けているので、化粧シート５の繰り出しと同時により保護シート７を巻き芯１５に巻き取ることができる。
【００７１】
検尺手段７４を使用する際は、検尺ローラー８５が原反ロール９に当接した状態で化粧シート５を繰り出していけば、その繰り出し量がカウンター８６に表示されるので、所定の量を繰り出したところで裁断案内手段７２の案内により裁断すれば良い。また付勢手段８４により検尺ローラー８５が原反ロール９側に付勢されているので、原反ロール９の径が大きいときは勿論のこと、化粧シート５の繰り出しに伴って原反ロール９の径が小さくなったときにも、検尺ローラー８５を原反ロール９に確実に当接させることができ、繰り出された化粧シート５を正確に検尺することができる。
【００７２】
図１６及び図１７は本発明の第３の実施形態を例示する。この実施形態の回転防止手段３１は、回転軸２５，２８の内部に配置され且つ巻き芯８，１５の内面に圧接すべく回転軸２５，２８から出入する一対の圧接片５９と、この圧接片５９を回転軸２５，２８から出入させ且つその出入状態を保持するための操作手段６０とを備えている。
【００７３】
各圧接片５９は略円形の板状で、その一部が重なり合うように略平行に配置され、その重なり部分で共通の枢軸６１により偏心状に枢支されている。枢軸６１は回転軸２５，２８を径方向に貫通して固定されている。そして各圧接片５９はこの枢軸６１廻りに回転したときに、回転軸２５，２８にスリット状に形成された出入口６２から出入するようになっている。なお、回転軸２５，２８は、全体を中空筒状に構成しても良いし、必要部分のみを中空にしても良い。
【００７４】
また圧接片５９は、第１の実施形態の弾性帯状片３２と同様に、巻き芯８，１５に回転軸２５，２８を挿通した際に、巻き芯８，１５の軸心方向の略中央に位置するように配置されているが、巻き芯８，１５に挿入される部分であれば巻き芯８，１５の中央から偏った位置となるように配置しても良いし、回転軸２５，２８の軸心方向に一対又は複数組設けても良い。
【００７５】
操作手段６０は、回転軸２５，２８の係合凹部４０と反対側に設けられた操作つまみ６３と、回転軸２５，２８内に軸心方向に配置され且つ一端が操作つまみ６３に一体回転可能に連結されたねじ軸６４と、回転軸２５，２８内に軸心方向に移動自在に設けられ且つ軸心方向の往復移動により各圧接片５９を枢軸６１廻りに逆方向に出入回転させる誘導部材６５とを備え、ねじ軸６４の他端のねじ部６４ａが誘導部材６５の雌ねじ部６５ｃに螺合されている。なお、ねじ軸６４に雌ねじ部を、誘導部材６５にねじ部を夫々設けても良い。
【００７６】
誘導部材６５は、回転軸２５，２８の内部に回転不能に配置され、枢軸６１の軸心方向の両側から圧接片５９を挟む挟持部６５ａと、回転軸２５，２８の軸心方向の両側で圧接片５９に接触して枢軸６１廻りに正逆回転させる誘導部６５ｂとにより圧接片５９を取り囲む矩形枠状に構成されている。また誘導部材６５は、その両挟持部６５ａに枢軸６１を挿通するための長孔６６が形成されており、この長孔６６の範囲内で回転軸２５，２８の軸心方向に往復移動可能になっている。
【００７７】
誘導部材６５の雌ねじ部６５ｃは、操作つまみ６３側の誘導部６５ｂの外側のボス部６７に形成されており、この雌ねじ部６５ｃにねじ部６４ａが螺合されたねじ軸６４を操作つまみ６３により正逆回転した際に、誘導部材６５が回転軸２５，２８の軸心方向に往復移動するようになっている。
【００７８】
誘導部材６５は、その進退に際して、図１６（ａ）に実線で示すように巻き芯８，１５の内面に対する圧接位置と仮想線で示す退避位置との間で、その誘導部６５ｂにより圧接片５９を枢軸６１廻りに出入回転させると共に、操作つまみ６３が操作されないときには、圧接片５９の回転を誘導部６５ｂで規制し、圧接片５９を圧接位置又は退避位置に保持するようになっている。
【００７９】
また回転軸２５，２８の操作つまみ６３側の端部には、ねじ軸６４の一端側を回転自在に支持する支持部材７１が嵌合されてねじ等により固定されている。支持部材７１は、回転軸２５，２８の端部から操作つまみ６３側へと突出し且つ回転軸２５，２８よりも小径に形成された突出部７１ａを備えており、図１７に示すように、連結保持手段４８の第２規制部材５０に、規制位置のときに突出部７１ａが嵌合する切り欠き６８が形成されている。
【００８０】
なお、支持部材７１に雌ねじ部を設け、この雌ねじ部にねじ軸６４を軸心方向に往復移動自在に螺合し、ねじ軸６４の他端を誘導部材６５に単に回転自在に連結した構成にしても良い。
【００８１】
回転防止手段３１はこの実施形態のように構成しても良い。この場合、操作つまみ６３を回転操作したときに、ねじ軸６４、誘導部材６５を介して圧接片５９が回転軸２５，２８から出入し、圧接位置で巻き芯８，１５の内面にねじ力により強固に圧接するので、回転軸２５，２８と巻き芯８，１５との相対回転を確実に防止することができる。また巻き芯８，１５に回転軸２５，２８を挿通する際には、操作つまみ６３を操作して圧接片５９を退避位置にしておけば、巻き芯８，１５に回転軸２５，２８を円滑に挿通することができる。
【００８２】
なお、この実施形態でも、回転防止手段３１により回転軸２５，２８と巻き芯８，１５との軸心方向の相対移動を防止することが可能である。さらに、回転軸２５，２８と巻き芯８，１５とを回転防止手段３１により略同心状に固定できるので、それらの回転時の重心移動を少なくでき、化粧シート５の繰り出し、保護シート７の巻き取りを円滑に行なうことができる。
【００８３】
図１８は本発明の第４の実施形態を例示する。この実施形態は、第３の実施形態の圧接片５９を長円形の板状に形成すると共に、誘導部材６５のねじ軸６４側の誘導部６５ｂを誘導ピン８８により構成したものである。その他の構成は第３の実施形態と略同様である。
【００８４】
一対の圧接片５９は、長円形の長手方向の一端側が重なり合うように略平行に配置され、その重なり部分で枢軸６１により枢支されており、この枢軸６１廻りに回転したときに、回転軸２５，２８の出入口６２から出入するようになっている。
【００８５】
誘導部材６５は、ねじ軸６４と反対側の誘導部６５ｂが第３の実施形態と略同様に構成されると共に、ねじ軸６４側の誘導部６５ｂが長孔６６の両出入口６２側に配置された一対の誘導ピン８８により構成されている。各誘導ピン８８は、圧接片５９よりもねじ軸６４側で両挟持部６５ａ間に固定されており、仮想線で示すように誘導部材６５がねじ軸６４と反対側に移動するときに、各圧接片５９を入方向に誘導するようになっている。
【００８６】
圧接片５９及び誘導部材６５はこのように構成しても良い。この実施形態の構成では、第３の実施形態と略同様の効果を得ることができる上に、圧接片５９の回転軸２５，２８からの突出量を大きくできるので、巻き芯８，１５と回転軸２５，２８との回転防止作用をさらに大きくすることができる。
【００８７】
以上、本発明の各実施形態について詳述したが、本発明は各実施形態に限定されるものではなく、趣旨を逸脱しない範囲で種々の変更が可能である。例えば、回転防止手段３１は、回転軸２５，２８と巻き芯８，１５との相対回転を防止できれば十分であり、各実施形態に例示した構成でなくても良い。しかし、巻き芯８，１５に回転軸２５，２８を挿通する際の操作性、また生産コスト等を考慮して、各実施形態に例示したような簡単で且つ十分な効果を得ることができる構成にすることが望ましい。
【００８８】
回転軸２５，２８と連動軸３６，３７との連結構造も適宜変更可能である。実施形態では連動軸３６，３７に係合突起３９を、回転軸２５，２８に係合凹部４０を夫々形成しているが、夫々逆に形成しても良い。また、連動軸３６，３７を中空筒状とし、その径方向の内側に突出する係合突起３９を設け、連動軸３６，３７の中空内に先端が嵌合する回転軸２５，２８に係合凹部４０を設けても良い。なお、係合部及び被係合部を回転軸２５，２８と連動軸３６，３７との一方及び他方に設け、その係合により回転軸２５，２８と連動軸３６，３７とが連動する構成であれば十分である。
【００８９】
連結保持手段４８の構成も適宜変更しても良い。実施形態では、連動手段１７と反対側の側板１８に固定した第１規制部材４９及び第２規制部材５０により連結保持手段４８を構成しているが、連結保持手段４８は連動手段１７側の側板１８、連結部材１９等、支持枠１１の適宜箇所に設けても良いし、その構成も適宜変更可能である。例えば、回転軸２５，２８にフランジを設け、このフランジと、その左右方向及び上側への移動を規制する規制部材とにより連結保持手段４８を構成しても良い。
【００９０】
また実施形態では、回転軸２５，２８の両端側が嵌合する嵌合凹部２６，２９を支持枠１１の側板１８に上側から切り欠き状に形成しているが、嵌合凹部２６，２９は、回転軸２５，２８が上側から着脱自在に嵌合する構成であれば十分であり、例えば、側板１８から上方に突出する前後一対の突起間に形成しても良い。
【００９１】
実施形態では、作業者が人為的に化粧シート５を引き出す場合を例示しているが、繰り出し手段１３及び／又は巻き取り手段１６を同一又は別のモータで駆動するようにしても良い。繰り出し手段１３及び巻き取り手段１６を別のモータにより駆動する場合には、各モータの速度制御により化粧シート５の繰り出し速度と保護シート７の巻き取り速度とを一致させることも可能であり、その制御手段により連動手段１７を構成すればよい。更に支持枠１１のキャスター車輪１２をモータで駆動することも可能である。また繰り出し手段１３、巻き取り手段１６、キャスター車輪１２等をモータで駆動する場合には、無線又は有線方式で遠隔操作可能に構成しても良い。
【００９２】
実施形態では、裏面に糊６を塗布して保護シート７で保護した化粧シート５を使用する場合を例示しているが、再湿式の再湿糊を使用した化粧シート５、糊６を塗布していない化粧シート５を使用することも可能である。但し、再湿糊を使用した化粧シート５の場合には、原反ロール９から化粧シート５を繰り出した後に、その糊６面に水を塗布する水塗布手段を設け、また糊６を塗布していない化粧シート５の場合には、原反ロール９から化粧シート５を繰り出した後に、裏面に糊６を塗布する糊塗布手段を設ければ、実施形態と同様の手順で壁面３に化粧シート５を貼着することが可能である。なお、糊６は生糊等が適当であるが、その他の接着剤を糊６として使用しても良い。
【００９３】
なお、本発明の繰り出し装置１０は、支持枠１１に、化粧シート５の原反ロール９を着脱自在に支持する繰り出し手段１３と、原反ロール９から繰り出された化粧シート５を壁面３側へと案内する案内手段１４とを備え、繰り出し手段１３は、原反ロール９の巻き芯８にその軸心方向に貫通状に挿通される回転軸２５を備え、支持枠１１に、回転軸２５の軸心方向の両端側に対応して、回転軸２５が上側から着脱自在に嵌合する嵌合凹部２６と、その嵌合状態で前記回転軸２５を下側から回転自在に支持するローラー２７とを設けた構成とし、巻き取り手段１６、連動手段１７等を設けなくても良い。この場合には、再湿糊を使用した化粧シート５又は糊６を塗布していない化粧シート５など、保護シート７を有しない化粧シート５の使用に適しているが、保護シート７を有する化粧シート５を使用しても良い。
【００９４】
支持枠１１の高さを高く（例えば１ｍ程度）して、その上部に繰り出し手段１３、案内手段１４等を設けて、作業者が脚立２４等の作業足場から降りずに支持枠１１を移動させながら作業を行えるようにしても良い。またその場合、案内手段１４の案内軸５５をモータ等により昇降可能に設けると共に、案内軸５５に沿って化粧シート５を切断する自動切断手段を設け、案内手段１４を下降させた後、自動切断手段で化粧シート５を幅方向に切断するようにしても良い。
【００９５】
各構成部材に使用すべき材料は、金属、合成樹脂の何れであっても良い。但し、剛性、強度等が要求される構成部材、耐摩耗性、摩擦力等が要求される構成部材にはその剛性、強度、耐摩耗性、摩擦力等を満たす材料を使用することはいうまでもない。
【００９６】
【発明の効果】

【００９７】
また支持枠１１に、化粧シート５の原反ロール９を着脱自在に支持する繰り出し手段１３と、前記原反ロール９から繰り出された前記化粧シート５を壁面３側へと案内する案内手段１４と、前記原反ロール９から繰り出された化粧シート５の裏面側の糊６用の保護シート７を巻き芯１５に巻き取る巻き取り手段１６と、前記繰り出し手段１３と前記巻き取り手段１６とを連動させる連動手段１７とを備え、前記繰り出し手段１３及び巻き取り手段１６は、前記原反ロール９及び前記保護シート７用の巻き芯８，１５にその軸心方向に貫通状に挿通され且つ前記支持枠１１に着脱及び回転自在に装着される回転軸２５，２８を備え、該回転軸２５，２８に、該回転軸２５，２８と前記巻き芯８，１５との相対回転を防止する回転防止手段３１を設けているので、予め壁面３を採寸して化粧シート５を裁断しておく必要がなく、原反ロール９から化粧シート５を引き出して壁面３に直接貼着できる。しかも、化粧シート５の繰り出しによる原反ロール９の回転動力を、巻き取り手段１６側の巻き芯１５に確実に伝達することができ、保護シート７を巻き芯１５に確実に巻き取ることができる。

It also has a function as a member.
[0035]
When the decorative sheet 5 is adhered to the wall surface 3 by the feeding device 10 having the above configuration, first, the feeding rotary shaft 25 is wound on the winding core 8 of the material roll 9, and the winding shaft 15 is wound on the winding core 15 for the protection sheet 7. 28 respectively. At this time, the elastic strip 32 is wound around each of the rotating shafts 25 and 28, and while rotating the rotating shafts 25 and 28 in a direction opposite to the winding direction, from the fixed portion of the inclined edge 33a of the elastic strip 32 to the tip side. If the insertion directions of the rotating shafts 25 and 28 into the winding cores 8 and 15 are opposite to each other, the rotating shafts 25 and 28 can be easily inserted through the winding cores 8 and 15. Can be. Then, the elastic strips 32 are pressed against the inner surfaces of the winding cores 8 and 15 due to their elasticity while trying to expand inside the winding cores 8 and 15, so that the relative positions of the rotating shafts 25 and 28 and the winding cores 8 and 15 are increased. Rotation can be prevented.
[0036]
Next, the rotating shafts 25 and 28 are mounted on the support frame 11. At this time, the connecting and holding means 48 is set at the permissible position around the pivot 51, the ends of the rotating shafts 25 and 28 on the side of the engagement recess 40 are fitted over the distal ends of the interlocking shafts 36 and 37, and the rotating shafts 25 and 28 are connected. The support frame 11 is fitted into the fitting recesses 26 and 29 of the side plate 18 from above. Then, the engaging projections 39 of the interlocking shafts 36 and 37 engage with the engaging recesses 40 of the rotating shafts 25 and 28, and the rollers 27 and 30 fixed to the side plate 18 rotate the rotating shafts 25 and 28 from below. The rotating shafts 25 and 28 and the interlocking shafts 36 and 37 are interlockingly rotated.
[0037]
Further, the rotating shafts 25 and 28 are loosely fitted and connected to the interlocking shafts 36 and 37 to receive the load on the rotating shafts 25 and 28 by the rollers 27 and 30 and to move the rotating shafts 25 and 28 by the rollers. 27, 30 and the side plate 18, the load on the rotating shafts 25, 28 is not applied to the interlocking shafts 36, 37, and damage to the interlocking shafts 36, 37, the interlocking mechanism 17a, etc. is prevented. Can be prevented.
[0038]
When each of the rotating shafts 25 and 28 is mounted on the support frame 11, the connecting and holding means 48 is set to the restricting position around the pivot 51, and the other end of the first restricting member 49 is fixed by the screw 52. This prevents the connection between the rotating shafts 25 and 28 and the interlocking shafts 36 and 37 from being accidentally disconnected due to the feeding of the decorative sheet 5 or the like.
[0039]
Before and after the rotation shafts 25 and 28 are mounted on the support frame 11, the vertical angle of the support arm 54 of the guide means 14 is adjusted by operating the thumb screw 56, and the guide shaft is adjusted according to the cutting position of the decorative sheet 5. Adjust the vertical position of 55. When the baseboard 4 is located at the lower end of the wall 3, the guide shaft 55 is adjusted to the height of the upper end of the baseboard 4. Incidentally, the width of the baseboard 4 is generally 5 cm, 7.5 cm, and 10 cm. If the baseboard 4 is not provided, the guide shaft 55 is adjusted so that the guide shaft 55 does not contact the floor 1 near the lower end of the wall 3. In addition, the baseboard 4 may be laminated and attached from the front side after the decorative sheet 5 is attached.
[0040]
In actual application of the decorative sheet 5, first, the end of the decorative sheet 5 is pulled out from the material roll 9 toward the guide shaft 55, and the end of the protective sheet 7 peeled from the decorative sheet 5 is taken up by the winding means 16. Stop on the core 15. Then, the decorative sheet 5 is fed out from the material roll 9 through the lower side of the guide shaft 55 to the wall surface 3 side.
[0041]
Then, the web roll 9 and the feeding rotary shaft 25 rotate in conjunction with each other by the action of the elastic strip 32 of the rotation preventing means 31, and the rotation power is transmitted to the winding rotary shaft 28 via the linking means 17, and the winding is performed. The winding core 15 fitted on the rotating shaft 28 rotates in the winding direction by the action of the elastic strip 32 of the rotation preventing means 31. Therefore, if the decorative sheet 5 is unwound, the protective sheet 7 can be wound around the core 15 in synchronization with the unwinding of the decorative sheet 5 from the raw roll 9.
[0042]
The take-up rotary shaft 28 is increased in speed relative to the feed rotary shaft 25 by the gear ratio between the large-diameter gear 41 and the small-diameter gear 42, and the transmission belt 45 and the driving pulley 43 and / or the driven pulley 44 Since the slippage occurs between the rolls, the feeding speed of the decorative sheet 5 on the feeding means 13 side and the feeding speed of the decorative sheet 5 on the feeding means 13 side are changed despite the change in the diameter of the raw roll 9 and the diameter of the wound protective sheet 7. The winding speed of the protective sheet 7 on the winding means 16 side can be kept substantially the same, and the protective sheet 7 can be wound in a predetermined tension state. Therefore, the unwinding of the decorative sheet 5 and the winding of the protective sheet 7 can be performed smoothly without any abnormal resistance being applied to the unwinding of the decorative sheet 5 or the protective sheet 7 being broken due to an increase in tension. it can.
[0043]
In addition, since the guide shaft 55 of the guide means 14 rotates with the lifting of the decorative sheet 5, the resistance of the guide shaft 55 is small. The decorative sheet 5 can be smoothly guided along the wall surface 3 from near the lower side.
[0044]
When the upper end of the decorative sheet 5 reaches the upper end of the sticking position, the decorative sheet 5 is stuck to the wall surface 3 with the upper end thereof aligned with the upper end of the sticking position and stopped. As a result, the decorative sheet 5 hangs down along the wall surface 3, so a cutter is applied to the guide shaft 55, and the decorative sheet 5 is cut substantially linearly in the width direction while moving the cutter along the guide shaft 55. . Then, the decorative sheet 5 is stuck on the entire sticking portion of the wall surface 3 with the glue 6 on the back side.
