Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、左官用こての改良に関するものである。[Detailed description of the invention] (Industrial application field) The present invention relates to an improvement in a plastering trowel.
（従来の技術）
従来の左官用こては、セメント等を平らに仕上げるため
の平らな表面部が金属で形成されていた。(Prior Art) A conventional plastering trowel has a flat surface portion made of metal for flattening cement or the like.
ところが、最近の建築物では耐水性や強度増加の観点か
ら、セメントに種々の化学物質を混入するためセメント
の粘性が増し、そのためにこての滑りが悪くしたがって
こてのセメント離れも悪いという不都合が生じていた。However, in recent constructions, various chemicals are mixed into cement in order to improve its water resistance and strength, which increases the viscosity of the cement, which makes it difficult for the trowel to slide, making it difficult for the trowel to separate from the cement. was occurring.
（本発明が解決しようとする問題点）
従来のこては上述のような欠点を有しており、そのため
、こての表面に種々の滑り材を塗付する方法も考えられ
たのであるが、セメントが粒状で硬度が大きいために短
期間で滑り材が剥がれ落ちてしまうこととなり、実用で
きなかった。(Problems to be Solved by the Present Invention) Conventional trowels have the above-mentioned drawbacks, and for this reason, methods of applying various slipping materials to the surface of the trowel have been considered. However, because the cement was granular and hard, the sliding material would peel off in a short period of time, making it impractical.
本発明は、セメントに対する滑りを良くシ、かつ滑り具
合を長期間にわたり保つことのできるこてを堤供するこ
とを目的とするものである。The object of the present invention is to provide a trowel that can slip well against cement and maintain that slippage over a long period of time.
（問題を解決するための手段）
本発明の構成を実施例として示す図面に従って説明する
。(Means for Solving the Problems) The configuration of the present invention will be explained with reference to the drawings showing examples.

できるので、この実施例のこてが製造できる。1 and 2 show a first embodiment, in which a main body 1 has an ultra-high molecular weight polyethylene plate 4 adhered to the surface of a metal plate 2 via a synthetic rubber portion 3. Ultra-high molecular weight polyethylene has extremely strong non-stick properties and is difficult to adhere to metals. For this reason, the trowel of this embodiment can be manufactured because synthetic rubber, which is manufactured by laminating and integrating synthetic rubber during the manufacture of ultra-high molecular weight polyethylene plates, can be bonded to metal.

A dovetail groove 5 is provided in the upper surface of the main body l in the longitudinal direction. The front part of the dovetail groove 5 is covered with an outer wall 6 and becomes a dead end, and the rear part is an open lower part. A locking protrusion 8 is formed on the lower surface of this open lower. And these main bodies 1. The dovetail grooves 5 and protrusions 8 provided thereon are all integrally molded from ultra-high molecular weight polyethylene.

板部１１があり溝５から抜け出ることを防止できる。An insertion plate portion 11 is attached to the separate grip member 9 via one leg portion 10 on the lower side. This insertion plate portion 11 has an elongated rectangular shape, and its length is equal to the length of the dovetail groove 5 minus the width of the protrusion 8. Therefore, insert the insertion plate part 1] from the open lower part of the dovetail groove 5, and
．． When the grip member 9 completely passes over the protrusion 8, the main body 1 and the grip member 9 are in a connected state. Further, due to the action of the protrusion 8, the insertion plate portion 11 can be prevented from slipping out of the groove 5.

とができる。(Operations and Effects) The present invention has the above configuration, and the flat surface portion for flattening cement and the like is formed of ultra-high molecular weight polyethylene. Since ultra-high molecular weight polyethylene has high non-adhesive properties and self-lubricating properties (surface sliding properties), it can reduce the resistance between cement and a trowel when cutting cement, etc. mixed with chemical substances. As a result, one worker can work easily with the iron without requiring much force.

おいて産業上利用できる優れた発明である。Ultra-high molecular weight polyethylene is a new material that has recently appeared, and the present invention is an invention for its use. New materials have the potential to be used for a variety of purposes, but it is difficult to say that they have been sufficiently developed for applications that can take full advantage of their properties, and their self-lubricating properties are extremely poor. The present invention has the disadvantage of being difficult to handle due to its large size, and cannot be used as is for any purpose.The present invention is an excellent product that can be used industrially in that it can realize one such use of ultra-high molecular weight polyethylene. It is an invention.
