Abstract

A scraper includes a blade body having a rear end and an opposite front end. The blade body has an end surface at the front end, with a lower surface and an opposite upper surface connected on each side of the end surface. The upper surface is provided with a plurality of grooves, and one end of each groove is connected to the end surface, and the other end extends towards the rear end. A distance from the junction between the upper surface and the end surface to the lower surface forms a first thickness, and a distance from the junction between the grooves and the end surface to the lower surface forms a second thickness. The second thickness is smaller than the first thickness. Thus, the scraper can provide efficient scraping performance while maintaining good structural strength.

刮刀scraper

本發明主要係揭示一種刮刀，尤指兼具良好刮除效率與結構強度的刮刀。The present invention mainly discloses a scraper, in particular a scraper with good scraping efficiency and structural strength.

請參閱我國專利第M253457號之「多功能工具」專利案，其為一種多功能工具，其包括有一握柄，以及一插設結合於握柄一端之刀身，該刀身係具有不規則形狀之操作部，該操作部主要在刀身前端位置設有一平刮刀部，且於中段處設有拔釘孔及後端設有開瓶孔，該操作部更包括有第一側及第二側，且該第一側依序設有扳部、凹弧刮刀部、切刀部，該第二側則依序設有尖刀部、漆布刀部、凸弧刮刀部。Please refer to the "Multi-function Tool" patent case of Taiwan's patent No. M253457, which is a multi-function tool, which includes a handle and a blade inserted and combined at one end of the handle. The blade has an irregularly shaped operating portion. The operating portion is mainly provided with a flat scraper portion at the front end of the blade, and a nail extraction hole is provided in the middle section and a bottle opening hole is provided at the rear end. The operating portion further includes a first side and a second side, and the first side is provided with a lever portion, a concave arc scraper portion, and a cutting knife portion in sequence, and the second side is provided with a sharp knife portion, a varnished cloth knife portion, and a convex arc scraper portion in sequence.

使用上述工具在平面區域作業，如刮除或塗佈漆料時，所使用的部位是平刮刀部，然而，上述工具的平刮刀部僅呈將金屬板件直邊磨利的鋒刃狀，容易磨損或變形，而改善其缺陷最直觀的做法是增加平刮刀部的厚度，但若增加平刮刀部的厚度將導致其不夠鋒利而影響操作手感，也降低刮除效率。When the above-mentioned tool is used to operate on a flat area, such as scraping or applying paint, the part used is the flat scraper portion. However, the flat scraper portion of the above-mentioned tool is only in the shape of a sharp blade sharpened from the straight edge of a metal plate, and is easily worn or deformed. The most intuitive way to improve its defects is to increase the thickness of the flat scraper portion. However, if the thickness of the flat scraper portion is increased, it will not be sharp enough, which will affect the operating feel and reduce the scraping efficiency.

有鑑於上述習知結構之缺失，本發明人乃設計出一種刮刀，其係可克服上述習知結構之所有缺點。In view of the defects of the above-mentioned conventional structures, the inventors have designed a scraper which can overcome all the defects of the above-mentioned conventional structures.
