Description

本発明は、手持ち電動切断機体に装着され、絨毯切断用に使用される刃体に関するものである。 The present invention relates to a blade body mounted on a hand-held electric cutting machine body and used for carpet cutting.

手持ちの電動切断機体は、電動機を内装して、電動機の回転動作を往復動作に変換し、往復動作として出力される個所に刃体の装着部を設けて刃体を連結し、刃体の往復駆動で各種対象物の切断を行っている。 A hand-held electric cutting machine is equipped with an electric motor, converts the rotational movement of the electric motor into a reciprocating operation, and connects the blade body by connecting the blade body at the location where it is output as the reciprocating operation. Various objects are cut by driving.

切断刃の形状は特許文献１（特開平８−２２９２４８号公報）記載のような包丁様の直刃や、特許文献２（実開平６−３１６５４号公報）に開示されている鋸歯状押切刃や、特許文献３（特開２０１１−７３１７５号公報）に開示されている鋸歯状引切刃などが知られている。 The shape of the cutting blade is a knife-like straight blade as described in Patent Document 1 (Japanese Patent Application Laid-Open No. 8-229248), a saw-toothed pressing blade disclosed in Patent Document 2 (Japanese Utility Model Publication No. 6-31654), A saw-toothed cutting blade disclosed in Patent Document 3 (Japanese Patent Laid-Open No. 2011-73175) is known.

絨毯用駆動切断装置は、手持ちの電動切断機体に前記した直刃を装着して使用しているもので、丸めて束ねた絨毯に対して、直刃を往復動作させて切断していたものであるが、絨毯に丈夫な繊維が使用されていた場合には、切断作業に時間を要してしまう。また鋸歯状の刃体を使用すると切断屑が発生してしまう問題がある。 The carpet driving cutting device is used by attaching the above-mentioned straight blade to a hand-held electric cutting machine body, and cutting the straight blade with a reciprocating motion with respect to the rolled up and bundled carpet. However, when a strong fiber is used for the carpet, it takes time for the cutting work. Moreover, there is a problem in that cutting waste is generated when a sawtooth blade is used.

そこで本発明は絨毯に対して効率的に切断することのできる新規な切断刃体を提案したものである。 Therefore, the present invention proposes a novel cutting blade that can efficiently cut a carpet.

本発明（請求項１）に係る絨毯用切断刃体は、長尺薄金属板製本体における基部に、手持ち電動切断機体に装着する装着部を設け、長尺下縁に、直線刃部及び適宜間隔毎に設けたＶ状の切り込み部を備えた刃部を設けてなることを特徴とするものである。 The carpet cutting blade body according to the present invention (Claim 1) is provided with a mounting portion to be attached to a hand-held electric cutting machine body at the base portion of the long thin metal plate body, and a straight blade portion and an appropriate portion at the long lower edge. A blade portion provided with a V-shaped cut portion provided at each interval is provided.

而して従前どおり手持ち電動切断機体に装着して絨毯用駆動切断装置として使用され、刃体を往復駆動させて絨毯の切断を行うもので、直線刃部での切断と共に、Ｖ状の切り込み部の刃先端面が絨毯繊維を引っかけるように切断するので、絨毯を効率的に切断できる。 Thus, it is used as a carpet driving cutting device by attaching it to a hand-held electric cutting machine body as before, and cutting the carpet by reciprocating the blade body. In addition to cutting with a straight blade portion, a V-shaped cutting portion Since the cutting edge surface of the blade is cut so as to catch the carpet fiber, the carpet can be cut efficiently.

また本発明（請求項２）に係る絨毯用切断刃体は、切り込み部を、本体の表裏に対して非直交角度で形成してなるもので、Ｖ状の切り込み部の刃先端面による切断機能が高められるものである。 Further, the carpet cutting blade body according to the present invention (Claim 2) is formed by forming the cut portion at a non-orthogonal angle with respect to the front and back of the main body, and has a cutting function by the blade tip surface of the V-shaped cut portion. It can be enhanced.

本発明の構成は上記のとおりで、直線刃部に適宜間隔でＶ状の切り込みを入れ、直線刃の切断機能に、更に鋸歯様の切断機能をも付加して、効率的な絨毯切断を可能としたものである。 The configuration of the present invention is as described above, and V-shaped cuts are made at appropriate intervals in the straight blade portion, and a saw blade-like cutting function is further added to the cutting function of the straight blade, enabling efficient carpet cutting. It is what.

次に本発明の実施形態について説明する。実施形態に示した絨毯用切断刃体は、基本的に従前のものと同様に長尺薄金属板製の全長１８５ｍｍの本体１において、下縁に刃渡り１４５ｍｍの刃部２、基部側に装着部３を設けたものである。 Next, an embodiment of the present invention will be described. The carpet cutting blade body shown in the embodiment is basically the same as the conventional one, in a main body 1 made of a long thin metal plate having a total length of 185 mm, a blade portion 2 having a blade span of 145 mm on the lower edge, and a mounting portion on the base side. 3 is provided.

刃部２は、直線刃部２１と、前記直線刃部２１に適宜間隔（４〜５ｍｍ）で、Ｖ状の切り込み部２２で構成されているものである。特に前記切り込み部２２は、図３に示すように本体１の表裏に対して直交せずに、角度αだけ斜めにしたＶ状の谷が形成されるように設けたものである。 The blade portion 2 is configured by a V-shaped cut portion 22 at an appropriate interval (4 to 5 mm) between the straight blade portion 21 and the straight blade portion 21. In particular, as shown in FIG. 3, the cut portion 22 is provided so as to form a V-shaped valley that is not perpendicular to the front and back of the main body 1 and is inclined by the angle α.

装着部３は、装着対象の手持ち電動切断機体Ａの装着部Ｂに対応する形状に形成したもので、装着部Ｂの背金Ｃの掛止軸Ｄに対応する鉤部３１と、背金Ｃに軸支した係止レバーＥに対応する係止溝３２を備えたものである。 The mounting portion 3 is formed in a shape corresponding to the mounting portion B of the hand-held electric cutting machine body A to be mounted. The mounting portion 3 corresponds to the hook shaft 31 of the back metal C of the mounting portion B and the back metal C. It is provided with a locking groove 32 corresponding to the locking lever E pivotally supported.

而して前記絨毯用切断刃体は、手持ち電動切断機体Ａの装着部Ｂに装着して使用されるもので、切断対象である絨毯Ｆに対して刃体を当て、刃体の往復運動で切断するもので、特に直線刃部２１の刃先ａで絨毯Ｆの切断を行うと共に、Ｖ状の切り込み部２２の刃先端面ｂにおいても切断するもので、特に刃先端面ｂにおいては、絨毯繊維を引っかけて強く引くことになり、多少硬い繊維であっても容易に切断することができ、絨毯の切断作業の効率を高めることができたものである。 Thus, the carpet cutting blade body is used by being mounted on the mounting portion B of the hand-held electric cutting machine body A. The blade body is applied to the carpet F to be cut, and the blade body is reciprocated. In particular, it cuts the carpet F with the cutting edge a of the straight blade portion 21 and also cuts the blade tip surface b of the V-shaped cut portion 22. In particular, the blade tip surface b hooks carpet fibers. Therefore, even a somewhat hard fiber can be easily cut, and the efficiency of the carpet cutting operation can be improved.
