Description

本発明は、車輌の板金塗装の作業時に起こる不要物の、車内への侵入を防ぐ養生シートに関する。 TECHNICAL FIELD The present invention relates to a curing sheet that prevents intrusion of unnecessary materials that occur during sheet metal painting work of a vehicle.

従来、車輌等におけるドア・トランク等を開いた状態、又外した状態での板金塗装作業時に、車内へ不要物(塵・ホコリ・塗料・鉄粉・パテ粉等)が飛散して車内の開閉口部から侵入し付着するのを防ぐ為に、車内への開閉口部を、養生シートで密閉し覆う養生作業が行なわれていた。その際に使用される様々な養生シート、新聞紙・フィルムシート等をマスキングテープや粘着テープで貼り合わせ、一枚の養生シートの様に加工し、その養生シートの外周縁部に車輌の開閉口部に合わせ、マスキング・粘着テープ等で接着し密閉していくように養生していくという作業方法が行なわれていた。しかし、新聞紙等を用いる方法では、作業の手間を要し効率も悪かった。そこで、その際に使用される様々な養生シートが、これまで近年開発されてきた。従来の車輌用養生シートは、片側端縁部に粘着テープの粘着面を付けながら、ロール状に巻き取っているものがある。(例えば、特許文献１参照。)(特許文献２参照。)(特許文献３参照。)(特許文献４参照。) Conventionally, when metal sheets are painted with the doors and trunks open or removed from the vehicle, unnecessary objects (dust, dust, paint, iron powder, putty powder, etc.) are scattered inside the vehicle and opened and closed. In order to prevent intrusion and adhesion from the mouth portion, a curing operation was performed in which the opening and closing port portion into the vehicle was sealed and covered with a curing sheet. Various curing sheets, newspapers, film sheets, etc. used at that time are bonded together with masking tape or adhesive tape, processed like a single curing sheet, and the opening and closing part of the vehicle at the outer peripheral edge of the curing sheet In line with this, a work method was adopted in which the film was cured by being adhered and sealed with masking / adhesive tape or the like. However, the method using newspaper or the like requires work and is inefficient. Therefore, various curing sheets used at that time have been developed in recent years. Some conventional vehicle curing sheets are wound in a roll shape with an adhesive surface of an adhesive tape attached to one side edge. (See, for example, Patent Document 1.) (See Patent Document 2.) (See Patent Document 3.) (See Patent Document 4.)

背景技術で述べた車輌の板金塗装に使用される養生シートには次のような問題点があった。車輌における車内への開閉口部は、フロントドア・リアドア・トランクが、車種によって様々なタイプが存在し、形状も異なる為に、上記に述べた公報物件の様々な養生シート、新聞紙、フィルムシート等をその開閉口部の寸法に合わせる為、折り曲げたり切り破り張り合わせるなど加工した上で、マスキング・粘着テープ等で車輌に貼り合わせ密閉させていくなど、大変に手間のかかるものであった。 The curing sheet used for vehicle sheet metal painting described in the background art has the following problems. There are various types of front doors, rear doors, and trunks in the vehicle according to the type of vehicle, and the shape of the doors is different, so various curing sheets, newspapers, film sheets, etc. of the publications mentioned above In order to match the size of the opening and closing part, it was very time-consuming, such as bending and cutting and pasting together, and then sticking it to the vehicle with masking / adhesive tape and sealing it.

又、養生シートをマスキング・粘着テープで車輌に貼り合わせる作業中には、初期の段階では車輌内側からも手を入れる事が出来、車外・車内の両側から養生作業が簡単に行なえるが、作業が進むにつれ、養生シートで開閉口部を密閉させる作業工程上、車内側から手を入れるなどの作業が困難になり、車輌外側からしか養生作業が出来なくなる為に、経験不足の作業者には、難しく熟練された高度な技術を有するものである。 In addition, during the work of bonding the curing sheet to the vehicle with masking / adhesive tape, it is possible to insert the hand from the inside of the vehicle at the initial stage, and the curing work can be easily performed from both inside and outside the vehicle. As the work progresses, it becomes difficult to put a hand from the inside of the vehicle on the process of sealing the opening and closing part with a curing sheet, and the curing work can only be done from the outside of the vehicle, so for inexperienced workers Have advanced skills that are difficult and skilled.

又、マスキング・粘着テープを貼る際に接着面に油分・塵・ほこり等の不純物が付着していると、粘着率が低下し剥がれるなど、従来のマスキング・粘着テープとして正常に機能しなくなる為、一度接着面をウエスにシンナー・シリコンオフ等を含ませ、よく拭き取り余分な不純物を取り除いた後に貼り合わせていくという、大幅に作業時間を要するものであった。 In addition, if an adhesive such as oil, dust, or dust adheres to the adhesive surface when applying masking / adhesive tape, it will not function properly as a conventional masking / adhesive tape. The adhesive surface was once wiped with a thinner, silicon-off, etc., then wiped off to remove excess impurities, and then bonded together, which required a lot of work time.

上記の様々な養生シート・フィルムシート・新聞紙・マスキングテープ・粘着テープ等が、すべての板金塗装作業が終了すると同時に、一度養生シートにマスキングテープ・粘着テープ等を貼ったものを、再度剥がして使用しようとすれば、養生シートが破れたり、マスキングテープを剥がす途中で、マスキングテープが、従来養生シートにマスキング・粘着テープが貼っていなかった箇所に貼りついたりと煩わしく、再利用が困難であるために使い捨てになり、更に、廃棄処分されるために起こる処理コストは膨大なものであった。 The above-mentioned various curing sheets, film sheets, newspapers, masking tapes, adhesive tapes, etc., once all the sheet metal painting work has been completed, once the masking tapes, adhesive tapes, etc. are applied to the curing sheets, they are peeled off again. If you try to do so, the curing sheet will be torn or the masking tape will be stuck on the part where the masking / adhesive tape has not been applied to the curing sheet in the middle of peeling the masking tape. In addition, the processing costs caused by being disposable and disposed of were enormous.

車内に不要物の侵入を防ぐ養生シートであって、ポリエチレンフィルムやポリプロピレンフィルム等のポリオレフィン系フィルム、ポリエステルフィルム、ナイロン系フィルム等の各種プラスチックフィルム、布、紙などから形成されるシートの外周縁部に、一方に挿し込み口を有するポリプロピレン、ポリエチレン等のプラスチック樹脂で形成された伸縮可能な仮止め部が、前記挿し込み口が前記シートの外側に向く様に設けられた、板金塗装用の養生シートである。 Curing sheet that prevents the intrusion of unwanted materials inside the vehicle, and the outer periphery of the sheet formed from polyolefin film such as polyethylene film and polypropylene film, various plastic films such as polyester film and nylon film, cloth, paper, etc. In addition, a temporary fastening portion that is formed of a plastic resin such as polypropylene or polyethylene having an insertion port on one side is provided such that the insertion port faces the outside of the sheet, and is used for curing sheet metal. It is a sheet.

上記した本発明の構成により、次に記す顕著な効果を得ることができる。従来、養生シートなどの外周縁部に、車輌に貼り合わせるために使用していたマスキング・粘着テープ等を使用せず、本発明の伸縮可能な挿し込み口を有する仮止め部にすることにより、今まで車輌における養生作業工程も大幅に変更されてくる。従来、車輌に装着してあるウェザストリップを外し、その外した箇所にマスキング・粘着テープを養生シートと共に貼り合わせて養生作業していた作業内容は、一切行なう事は無くなる。本発明の養生シートに接着してある伸縮可能な挿し込み口を、ウェザストリップを外した箇所に車輌の開閉口部に合わせて伸縮部を調整し挿し込むだけで、簡単に開閉口部の寸法が確保できるようになる。 With the configuration of the present invention described above, the following remarkable effects can be obtained. Conventionally, on the outer peripheral edge of the curing sheet, etc., without using the masking / adhesive tape etc. used for bonding to the vehicle, by making the temporary fixing part having the stretchable insertion port of the present invention, Until now, the curing work process in vehicles has also changed significantly. Conventionally, the contents of the work that has been carried out by removing the weather strip attached to the vehicle and pasting the masking / adhesive tape together with the curing sheet to the removed part will not be performed at all. The size of the opening / closing port can be easily adjusted by simply inserting the expansion / contraction insertion port bonded to the curing sheet of the present invention into the location where the weather strip is removed and adjusting the expansion / contraction part according to the vehicle's opening / closing port. Can be secured.

また従来のマスキング・粘着テープでの接着という貼り合わせ方ではなく、ポリプロピレン等のプラスチック樹脂からなる挿し込み式にしたため、何度でも脱着が可能になり、今迄のように養生シートへのマスキング・粘着テープの貼り間違えなど起こすこともない。 Also, instead of using conventional masking / adhesive tape bonding, it is made of an insertion type made of plastic resin such as polypropylene, so it can be attached and detached any number of times. There will be no mistakes in attaching the adhesive tape.

さらに、車輌外側・車輌室内側の両側から、従来のマスキング・粘着テープの接着してある養生シートを開閉口部に合わせて貼り合わせるなどの作業も一切必要無くなり、車輌外側からの養生作業だけで済むため、これまでの養生作業が未熟な作業者においても簡単に装着ができ、熟練された高度な技術は全く必要としないという、これまでの養生シートとは全く異なる養生シートである。 Furthermore, there is no need to perform any conventional work such as pasting the curing sheet with the masking / adhesive tape attached to the opening / closing port from both the outside and inside of the vehicle. Therefore, it is a curing sheet that is completely different from conventional curing sheets that can be easily mounted even by an unskilled worker and does not require any skilled advanced technique.

マスキング・粘着テープ等を一切使用しないために、粘着力を必要としなくなるため、余分な不純物を取り除く作業も無くなり、大幅な作業時間の短縮が約束される。また、伸縮可能な仮止め部自体に最初から養生シートが接着されてあるために、車輌の開閉口部に合わせる際に、養生シート・フィルムシート・新聞紙等を、切り破ったり折り曲げたりと加工する手間の掛かる作業自体も必要としなくなり、作業の効率化が図れる。 Since no masking / adhesive tape is used, no adhesive force is required, so there is no need to remove excess impurities, and a significant reduction in work time is promised. In addition, since the curing sheet is bonded to the retractable temporary fixing part itself, the curing sheet, film sheet, newspaper, etc. are processed to be cut or bent when fitting with the opening and closing part of the vehicle. The time-consuming work itself is not necessary, and the work efficiency can be improved.

本発明の養生シートは、今まで当然のように使用されてきた、マスキング・粘着テープを一切使用していないため、マスキング・粘着テープを剥がす際に養生シートが破れる等のトラブルが一切無くなり、板金塗装作業終了時に本発明の養生シートをエアーブローなど清掃することにより、何度でも再利用が可能になるため、養生シートにおいてその使用済後の廃棄量の増大を抑制し、更に減少化へと導くエコロジー社会を推し進めるための一つの道を示す最大の効果であると考える。 Since the curing sheet of the present invention does not use any masking / adhesive tape, which has been used as a matter of course, there is no trouble such as tearing of the curing sheet when peeling the masking / adhesive tape. By cleaning the curing sheet of the present invention at the end of the painting work, such as air blow, it can be reused as many times as possible. I think that it is the greatest effect that shows one way to promote a leading ecological society.

以下、本発明の実施するための最良の形態について図面を参照しながら説明するが、本発明の養生シートの大きさ、形、伸縮可能な仮止め部の長さはこれらに限定されるものではない。まず、本発明に用いる養生シート３はポリエチレンフィルムやポリプロピレンフィルム等のポリオレフィン系フィルム、ポリエステルフィルム、ナイロン系フィルム等の各種プラスチックフィルム、布、紙などから形成される。図３に示すフロントドアに使用する場合は、紙の養生シート３の上側ａの長さを４００ｍｍ〜５５０ｍｍとし、これと平行に位置する下側ｂの長さを７００ｍｍ〜９５０ｍｍとする。下側ｂの端から上側ａに向かって垂直に伸びる左右の側部ｃ、ｄの向かって右側部ｃの長さを９００ｍｍ〜１１００ｍｍ、もう一方の向かって左側部ｄの長さを４５０ｍｍ〜６５０ｍｍとする。左側部ｄの長さの短い側の端より、上側ａの端に向かって伸びる辺ｅの長さを６００ｍｍ〜７５０ｍｍとし、このように養生シート３を五角形に裁断する。次にその養生シート３の外周縁部に、図１−Ａ、図１−Ｂ、図４で示すような厚みを０.５〜２mm、長さを３０５０mm〜４０００mmとした、一方に挿し込み口１を有するポリプロピレン、ポリエチレン等のプラスチック樹脂で形成れた伸縮可能な仮止め部４の挿し込み口１が、養生シート３より外側に向くように設置し、伸縮可能な仮止め部４の側面を養生シート３に接着剤を用いて接着する。また、電熱ヒーターにより接合密着させる方法もある。また、図１−Ｂに示す様に仮止め部４を伸縮可能にするための谷折り箇所ｆの幅の長さは７ｍｍ〜１３ｍｍとし、縦の長さｇを１２ｍｍ〜１５ｍｍとする。また、図１−Ａで示した挿し込み口１の長さは８ｍｍ程度が好ましい。 Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
