Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、フエルト針に関するものである。[Detailed explanation of the idea] [Industrial application field] The present invention relates to felt needles.
従来、フエルト針としては第４図に示すように
バーブ１３を、ブレード１２の長手方向全体に亘
つて一様に形成したものが知られている。
Conventionally, felt needles are known in which barbs 13 are formed uniformly over the entire length of the blade 12, as shown in FIG.
ところが、フエルト針はフエルトパンチ時にブ
レードに座屈力が作用するものであり、特にブレ
ードの中間部に最も座屈力がかかり、中間部で折
損する事故が生じ易いという問題点があつた。
However, the felt needle has a problem in that buckling force is applied to the blade during felt punching, and in particular, the buckling force is most applied to the middle part of the blade, making it easy to break the needle in the middle part.
本考案は、このような問題点を排除したフエル
ト針を提供することを目的とするものである。 The object of the present invention is to provide a felt needle that eliminates such problems.
本考案は、一端に針先を他端に柄部を備えたブ
レードにバーブを複数間隔を置いて形成したフエ
ルト針において、バーブをブレードの中間部分を
除いた針先側部分と柄部側部分とに形成したこと
を特徴とするフエルト針である。
The present invention is a felt needle in which a blade has a needle tip at one end and a handle at the other end, and a plurality of barbs are formed at intervals. This is a felt needle characterized by being formed with.
本考案のフエルト針では、ブレードの長手方向
中間部にバーブが形成されていないので、中間部
にはバーブ形成による断面縮少部が存在せず、中
間部の強度は他部に比べ向上する。
In the felt needle of the present invention, since no barb is formed in the longitudinally intermediate portion of the blade, there is no cross-section reduced portion due to barb formation in the intermediate portion, and the strength of the intermediate portion is improved compared to other portions.
本考案の実施例を図面により説明すると、第１

点がある。
The first embodiment of the present invention will be described with reference to the drawings.
The needle tip 6 is attached to one end and the handle 5 is attached to the other end as shown in FIGS.
In the felt needle 1 equipped with this, barbs 3 are formed on the needle tip 6 side and the handle 5 side of the triangular prism-shaped blade 2, excluding the longitudinally intermediate portion. 4 in the diagram
is a crank, and the cutting edges 7 are formed in three rows in the longitudinal direction of each corner edge of the blade 2, but the barbs 3 are formed in only one of the rows. Therefore,
There is no barb 3 in the middle part of the blade 2, which has a high incidence of breakage accidents, and this middle part has no reduced section, so its strength is improved compared to other parts. This has the advantage that blade breakage accidents are greatly reduced compared to a case where the blade edges are formed uniformly on all three rows of cutting edges over the entire area.
なお、３列の刃先のすべてにバーブを形成する
場合には、針先６側部分及び柄部５側部分のブレ
ードの任意横断面においてバーブが一つ以上現わ
れない形状のものとすることが、ブレードの強度
保持にとつて好ましい。また、ブレードを四角柱
以上の多角柱状や、円柱状に形成することもでき
る。 In addition, when barbs are formed on all three rows of blade edges, the shape should be such that one or more barbs do not appear in any cross section of the blade on the needle tip 6 side and the handle 5 side. This is preferable for maintaining the strength of the blade. Further, the blade can also be formed into a polygonal prism shape larger than a quadrangular prism, or a cylindrical shape.
以上述べたように本考案は、一端に針先を他端
に柄部を備えたブレードにバーブを複数間隔を置
いて形成したフエルト針において、バーブをブレ
ードの中間部分を除いた針先側部分と柄部側部分
とに形成したものであるから、ブレードの中間部
分にはバーブ形成による断面縮少部がなく、該部
の強度が向上し、使用中の折損事故が著しく減少
し、製作も容易である等の効果を奏する。
As described above, the present invention is a felt needle in which a blade is provided with a needle tip at one end and a handle at the other end, and a plurality of barbs are formed at intervals. Since the blade is formed on the side of the handle, there is no section reduction due to barb formation in the middle part of the blade, which improves the strength of this part, significantly reduces breakage accidents during use, and makes manufacturing easier. It has advantages such as ease of use.
