Description
本発明は、壁面クロス若しくはシート状床材を壁面若しくは床面から浮かせて連続的に切断する壁面クロス若しくはシート状床材剥離用のスクレーパー用刃に関するものである。 The present invention relates to a scraper blade for peeling wall cloth or sheet-like flooring material that continuously cuts the wall cloth or sheet-like flooring material while floating the wall surface cloth or sheet-like flooring material from the wall or floor surface.
壁面クロスやシート状床材の張替え作業に際にしては、先ず壁面や床面等の被貼着面に貼着された旧壁面クロスや旧シート状床材を剥離する必要がある。壁面クロスやシート状床材は、表面側から裏面側にかけて表面に装飾が施された装飾シート、不織布層、糊料層の３層よりなる。新しく張る壁面クロスやシート状床材の表面を平坦な美的なものにするには、旧壁面クロス若しくは旧シート状床材の表面層のみを剥離し、全ての不織布層を残存させ、この残存した旧壁面クロス若しくは旧シート状床材の不織布層の表面に、新しい壁面クロスやシート状床材の不織布層を新壁面クロス若しくは新シート状床材の糊料層を介して重合して貼着する。 When re-covering wall cloth or sheet-like flooring, it is first necessary to peel off the old wall cloth or sheet-like flooring that has been adhered to the surface to be adhered, such as the wall or floor. Wall cloths and sheet-like flooring materials consist of three layers: a decorative sheet whose surface is decorated from the front side to the back side, a nonwoven fabric layer, and an adhesive layer. In order to make the surface of a new wall cloth or sheet flooring material flat and aesthetically pleasing, only the surface layer of the old wall cloth or sheet flooring material is peeled off, leaving all the nonwoven fabric layers. Polymerize and adhere the nonwoven fabric layer of the new wall cloth or sheet flooring material to the surface of the nonwoven fabric layer of the old wall cloth or sheet flooring material via the adhesive layer of the new wall cloth or sheet flooring material. .
従来、壁面クロスの剥離作業にはカッターとスクレーパーの２つの道具を用いることが一般的に行われている。壁面クロスの剥離方法の一例として、クロスの繋ぎ面角部をカッターで引っ掛けて壁面から壁面クロスを捲り、この捲れた部分からスクレーパーのヘラ部を刃先側から壁面と壁面クロスとの境界部分に差し込み、この差し込み作業で捲れた壁面クロスを掴んで手前に引き剥がしていた。このような旧クロスの剥離作業に使用されるスクレーパーとしては、柄部と柄部に取り付けられる平板状のヘラ部を具備したもの（例えば、非特許文献１又は特許文献１～２参照）や、電動工具に平板状のヘラ部を着脱自在に取り付けたもの（例えば、非特許文献２参照）が知られている。 Conventionally, two tools, a cutter and a scraper, have been generally used to remove wall cloth. As an example of how to peel off wall cloth, hook the connecting corner of the cloth with a cutter, roll up the wall cloth from the wall surface, and insert the scraper part of the scraper from this rolled up part into the boundary between the wall surface and the wall cloth from the cutting edge side. , I grabbed the wall cloth that had been rolled up during this insertion process and pulled it off towards me. Examples of scrapers used for such old cloth stripping work include those equipped with a handle and a flat spatula attached to the handle (for example, see Non-Patent Document 1 or Patent Documents 1 and 2); BACKGROUND ART A power tool in which a flat plate-shaped spatula is detachably attached is known (for example, see Non-Patent Document 2).
しかしながら、上記従来のスクレーパーであると、スクレーパー自体に壁面クロスを切断する機能が備わっていない為、柄部の先端部が壁面から剥離された壁面クロス手前側の切縁に引っ掛かり、ヘラ部の進行が停止される。ヘラ部の進行が停止される都度、ヘラ部を壁面と壁面クロスとの間から抜き取り、捲れた壁面クロスを手前に引き剥がす作業を繰り返し行う必要があり、作業性が悪いという問題点があった。
又、ヘラ部で壁面クロスを浮かせることが可能な距離は、ヘラ部先端縁から柄部の基部までの直線距離が限界である。それ以上の距離は、捲れた壁面クロスを手前に引くことで剥離するため、剥離後の壁面には不織布層が剥離された部分と残存する部分が混在し、次の新しい壁面クロスが均一な面に仕上がらない場合があるという問題点があった。
However, with the above-mentioned conventional scraper, since the scraper itself does not have the function of cutting the wall cloth, the tip of the handle gets caught on the front incisal edge of the wall cloth that has been peeled off from the wall, and the scraper progresses. will be stopped. Each time the progress of the spatula part is stopped, it is necessary to repeatedly pull out the spatula part from between the wall surface and the wall cloth and peel off the rolled-up wall cloth toward the front, which poses a problem of poor work efficiency. .
Further, the distance over which the wall cloth can be floated by the spatula is limited to the straight distance from the tip of the spatula to the base of the handle. If the distance is longer than that, the rolled up wall cloth will be peeled off by pulling it toward you, so the wall surface after peeling will have a mixture of parts where the nonwoven fabric layer has been peeled off and parts where it remains, and the next new wall cloth will have a uniform surface. There was a problem that the finished product may not be finished.
シート状床材、例えばＣＦシート（クッションフロアシート）やリノリウムシート等の軟質性シートを床面から連続的に剥離する場合のスクレーパー刃としては、特許文献３の図面中の符号２８で示されるものが提案されている。特許文献３に開示のスクレーパー刃は、鋼板の先端部下面に研磨加工を施すことで傾斜面に形成され、尖鋭な先端を有する刃部に形成されている。 A scraper blade used to continuously peel off a sheet-like flooring material, such as a CF sheet (cushioned floor sheet) or a soft sheet such as a linoleum sheet, from a floor surface is the one shown by reference numeral 28 in the drawings of Patent Document 3. is proposed. The scraper blade disclosed in Patent Document 3 is formed into an inclined surface by polishing the lower surface of the tip of a steel plate, and is formed into a blade portion having a sharp tip.
特許文献３に開示のシート状床材剥離用のスクレーパー刃であると連続して剥離する機能はあるものの、剥離したシート状床材を切断する機能がなく、作業が非効率的であるという問題点があった。 Although the scraper blade for peeling sheet-like flooring disclosed in Patent Document 3 has the function of continuously peeling, it does not have the function of cutting the peeled sheet-like flooring, making the work inefficient. There was a point.
本発明はヘラ部上面に進行方向に刃先が向くカッターブレードを立設することで、ヘラ部で壁面クロス若しくはシート状床材を壁面若しくは床面から剥離しながら、剥離され浮き上がった壁面クロス若しくはシート状床材に進行方向に沿って切り目を形成することで、スクレーパーが進行を中断することがなく、旧クロスの剥離作業の短時間化及び剥離後の壁面や床面への残存する不織布の厚みの均一化を図るスクレーパー用刃を提供することを目的とする。 In the present invention, a cutter blade with a cutting edge facing in the advancing direction is installed on the top surface of the spatula part, and while the spatula part peels off the wall cloth or sheet-like flooring material from the wall or floor surface, the wall cloth or sheet that is peeled off and raised is removed. By forming cuts along the direction of movement in the flooring material, the scraper does not interrupt its progress, reducing the time it takes to remove old cloth and reducing the thickness of the nonwoven fabric remaining on walls and floors after peeling. The purpose of the present invention is to provide a scraper blade that achieves uniformity.
上記目的を達成するために本願発明のうち請求項１に記載の発明は、先端に剥離刃が備えられ平坦な下面を有するヘラ部と、取付部は、応力軽減可能な傾斜部を介在させて略並行な位置関係になるように一方向に沿って連設され、

The above numerical values are merely examples, and the characteristics of the present invention are not limited by these dimensions. As long as each can fulfill a predetermined role, each dimension may be larger or smaller, or may have a different size relationship or ratio.
次に作用及び効果について説明する。スクレーパー用刃１は、図６に示すように取付溝７に締着具を差し込んで柄１１を固定的に取り付けてスクレーパーとして使用するものである。１２は締着用ナットである。先ず、剥離する壁面クロスの装飾用シート９のうち壁面等から浮き上った部分若しくは繋ぎ面角部をカッターで引っ掛けて穴を形成し、この穴からヘラ部２の刃部６を差し込み、ヘラ部２の下面を壁面１３に残存する壁面クロスの装飾用シート９の下側の不織布層（図示省略）に当接する。この当接状態を保持しつつ、へラ部２を進行方向に移動させて使用するものである。 Next, the action and effect will be explained. The scraper blade 1 is used as a scraper by inserting a fastener into a mounting groove 7 and fixedly attaching a handle 11, as shown in FIG. 12 is a tightening nut. First, use a cutter to hook the part of the decorative sheet 9 of the wall cloth that is to be peeled off, or the corner of the connecting surface, with a cutter to form a hole, insert the blade part 6 of the spatula part 2 through this hole, and cut the The lower surface of the portion 2 is brought into contact with the lower nonwoven fabric layer (not shown) of the wall cloth decorative sheet 9 remaining on the wall surface 13. It is used by moving the spatula part 2 in the advancing direction while maintaining this abutting state.
へラ部２の先端が、左右横幅中心位置が最も突出した円弧状の刃部６に形成されているので、刃部６の最突出部に作用力が働き、壁面クロスの装飾用シート９は刃部６の最突出部を中心として少なくともヘラ部２の左右横幅分は剥離される。剥離された壁面クロスの装飾用シート９は、スクレーパ―用刃１の進行により受け部１０に案内され乗り上げられる。受け部１０に送り込まれた剥離された壁面クロスの装飾用シート９は、スクレーパー用刃１の進行により刃先８の反作用力で切断される。この切断部位をカッターブレード５は通過し、連続して壁面クロスの装飾用シート９は切断される。スクレーパーは、柄１１の存在を理由に進行を中断されることがない。へラ部２の通過した部分は、剥離した壁面クロスの装飾用シート９の不織布（図示省略）が壁面１３に貼着されている。ヘラ部２と取付部４は略平行な位置関係を有しているので、柄１１を把持した手が壁面等に接触することがなく使用できる。 Since the tip of the spatula part 2 is formed into an arc-shaped blade part 6 with the most protruding center position of the left and right width, the acting force acts on the most protruding part of the blade part 6, and the decorative sheet 9 of the wall cloth At least the left and right width of the spatula part 2 is peeled off with the most protruding part of the blade part 6 as the center. The peeled wall cloth decorative sheet 9 is guided to the receiving part 10 by the advance of the scraper blade 1 and rides on it. The peeled wall cloth decorative sheet 9 fed into the receiving part 10 is cut by the reaction force of the cutting edge 8 as the scraper blade 1 advances. The cutter blade 5 passes through this cutting portion, and the decorative sheet 9 of the wall cloth is continuously cut. The progress of the scraper is not interrupted due to the presence of the handle 11. A nonwoven fabric (not shown) of the peeled wall cloth decorative sheet 9 is adhered to the wall surface 13 through the portion through which the spatula portion 2 passes. Since the spatula part 2 and the attachment part 4 have a substantially parallel positional relationship, the handle 11 can be used without the hand grasping it coming into contact with a wall surface or the like.
尚、実施例１ではスクレーパー用刃１を柄１１に固定的に取り付けた手動式スクレーパーを例に説明したが、使用方法はこれに限定しない。上下方向に振動する駆動軸を有する電動工具（ 例えば、「電動スクレーパーコゲラ」株式会社三木技研の商品名）の駆動軸に
取付部４を一体的に連結させることで、受け部１０に送り込まれた剥離された壁面クロスの装飾用シート９を裏面側から表面側へと刃先８を上下動させて自動的に切断していくことも含まれる。
In the first embodiment, a manual scraper in which the scraper blade 1 is fixedly attached to the handle 11 is explained as an example, but the method of use is not limited to this. By integrally connecting the mounting part 4 to the drive shaft of a power tool (for example, "Electric Scraper Kogera", a product name of Miki Giken Co., Ltd.) having a drive shaft that vibrates in the vertical direction, This also includes automatically cutting the peeled wall cloth decorative sheet 9 by vertically moving the cutting edge 8 from the back side to the front side.
図８～図１２に示される実施例２について説明する。実施例２で示されるスクレーパー用刃１４は、主としてシート状床材剥離用のものである。
スクレーパー用刃１４は鋼板よりなり、同幅のヘラ部１５の後端を後方に延ばして連設し、床材剥離機１６に取り付け可能な取付部２２を設けている。ヘラ部１５の左右横幅を２分する中心位置を除く位置にカッターブレード１７を左右方向に所定距離を有して離隔した位置に設けている。ヘラ部１５の先端下面は後方に傾斜した傾斜面を有する刃部１８に形成されている。ヘラ部１５の先端縁形状は、左右横幅中心位置が最も進行方向に突出する平視円弧状を呈している。カッターブレード１７の先端は、ヘラ部１５の先端よりも後方に位置せしめて、ヘラ部１５の先端からカッターブレード１７の先端に亘る範囲を剥離したシート状床材の装飾用シート１９が送り込まれる受け部２０としている。取付溝２１は後端方を開口し、床材剥離機１６にヘラ部１５の露出長さを調整可能に取り付けられるようにしている。
Example 2 shown in FIGS. 8 to 12 will be described. The scraper blade 14 shown in Example 2 is mainly used for stripping sheet-like flooring materials.
The scraper blade 14 is made of a steel plate, the rear end of a spatula part 15 having the same width is extended rearward, and is provided with a mounting part 22 that can be attached to the flooring stripping machine 16. A cutter blade 17 is provided at a position apart from a center position dividing the left and right width of the spatula part 15 into two, and is spaced apart by a predetermined distance in the left and right direction. The lower surface of the distal end of the spatula portion 15 is formed into a blade portion 18 having a rearwardly inclined surface. The tip edge shape of the spatula part 15 is an arcuate shape in plan view, with the center position of the left and right widths protruding most in the traveling direction. The tip of the cutter blade 17 is positioned behind the tip of the spatula section 15, and serves as a receiver into which the decorative sheet 19 of the sheet-like flooring material that has been peeled off from the tip of the spatula section 15 to the tip of the cutter blade 17 is sent. Section 20. The attachment groove 21 is open at the rear end so that the spatula part 15 can be attached to the flooring peeling machine 16 so that the exposed length of the spatula part 15 can be adjusted.
次に、作用について説明する。スクレーパー用刃１４は床材剥離機２２、例えばペッカー（極東産機株式会社の商品名）のブラケット２３に取り付けられて使用する。一般的に床面はコンクリート躯体上に石膏ボード２４を配設し、隣り合う石膏ボード２４、２４間にパテ２５を埋め込んでおり、石膏ボード２４とパテ２５の上面にシート状床材の糊料層１９１を重合貼着している。シート状床材の装飾用シート１９を剥離する際に、並設された石膏ボード２４とパテ２５との位置関係を確認し、隣り合うカッターブレード１７、１７間にパテ２５が位置するようにして、パテ２５を損傷しないようにする必要性がある。そのため、図１０に示すように、先ずは並設された石膏ボード２４とパテ２５の延伸方向に直交する方向にスクレーパー用刃１４を進行させて、シート状床材の装飾シート１９を剥離する。次に、剥離された部分から確認されるパテ２５の配設位置がカッターブレード１７、１７間に位置するように、シート状床材の切縁１９２から刃部１８を差し込み、ヘラ部１５の下面をシート状床材の不織布１９３に当接状態を保持しながらスクレーパー用刃１４を進める。刃部１８で剥離されたシート状床材の装飾用シート１９は、受け部２０に送り込まれ、カッターブレード１７の刃先で切断される。切断されたシート状床材の装飾用シート１９は、四角形片になり廃棄処理が簡便化する。 Next, the effect will be explained. The scraper blade 14 is used by being attached to a bracket 23 of a flooring stripping machine 22, for example, Pecker (trade name of Kyokuto Sanki Co., Ltd.).
