【考案の詳細な説明】
作業の安全性及び取り扱いの簡便さから、ナイ

たりする不都合が生じ易い。[Detailed description of the invention] Nylon cords are sometimes used as mowing blades for brush cutters etc. due to work safety and ease of handling. Repeated contact or repeated contact between cords tends to cause the cords to break or weld together in a short period of time.
この対策としてコードの表面に潤滑剤を塗布せ
しめることが米国特許第4035912号で提案されて
いるが、ナイロンコードの表面は平滑であるので
保持性が悪く、折角塗布せしめた潤滑剤が簡単に
剥離してしまい、実用上ほとんど効果がない。 As a countermeasure to this problem, applying a lubricant to the surface of the cord is proposed in US Pat. No. 4,035,912, but since the surface of the nylon cord is smooth, it has poor retention, and the lubricant that has been applied to it easily peels off. This has almost no practical effect.
また、コードの表面を凹凸状の粗面として潤滑
剤の保持性を向上せしめることも考えられるが、
この場合も手が汚れたりする不都合がある。 It is also possible to improve lubricant retention by making the surface of the cord uneven.
In this case, too, there is an inconvenience that the hands become dirty.
本考案は、コードの材料に潤滑材を混入せしめ
ることにより、これらの不都合を取り除かんとす
るものである。 The present invention attempts to eliminate these disadvantages by incorporating a lubricant into the material of the cord.
次に図に示す実施例に基づき本考案を詳細に説
明する。 Next, the present invention will be explained in detail based on the embodiment shown in the figures.
本考案による草刈り用ナイロンコード６は、刈

引き出されて、草刈り刃として作用するものであ
る。 The nylon cord 6 for mowing according to the present invention is a shaft end 3 of a power transmission shaft 2 inserted into an operating rod 1 of a brush cutter.
The reel 5 is wound on a reel 5 housed in a casing 4 which is fixedly fixed to the casing 4 and rotates as a unit, and its free end 7 is pulled out outwardly through a through hole 8 provided in the peripheral wall of the casing 4. , which acts as a mowing blade.
構成に於いて、リール５に巻かれたコード６の
巻き解け部９及び自由端７の通孔８との接触部が
作業中に反復接触し、摩擦熱によりコードが溶け
て互いに溶着したり、切れたりするが、本考案で
はコードの材料に潤滑剤１１を混入せしめたの
で、潤滑剤の保持性が高く、コードの切断等に至
る迄の耐久時間が大巾に伸び、取り扱い上で手が
汚れることがなく、潤滑剤の無駄な消費も防止で
きる。 In this structure, the unwound portion 9 of the cord 6 wound on the reel 5 and the contact portion of the free end 7 with the through hole 8 come into contact repeatedly during operation, and the cords may melt due to frictional heat and weld to each other. However, in the present invention, the lubricant 11 is mixed into the cord material, so the lubricant retention is high, the durability time until the cord is cut is greatly extended, and it is easier to handle. It does not get dirty and prevents unnecessary consumption of lubricant.
混入する潤滑剤としては、粒径20〜50ミクロン
程度の二硫化モリブデン、グラフアイト等が適し
ており、ナイロンの総量に対して３〜20％程度の
範囲で均一に混入せしめれば目的が達せられる。
なお、コードの表面から0.2〜0.5mm程度の範囲に
潤滑剤が混入されていれば、実用上は十分効果を
発揮できる。 Molybdenum disulfide, graphite, etc. with a particle size of about 20 to 50 microns are suitable as lubricants to be mixed, and the purpose can be achieved if mixed uniformly in a range of about 3 to 20% of the total amount of nylon. It will be done.
Note that if the lubricant is mixed within a range of about 0.2 to 0.5 mm from the surface of the cord, it can be sufficiently effective in practice.
