Description

[Detailed description of the invention] (Industrial application field) This invention applies a hand to a hand tool having a handle such as a scraper for painting, a hand-held knife, etc.
The present invention relates to a device provided with a hitting portion that receives a hit with a hammer or the like.

(Problems to be Solved by Conventional Techniques and Inventions) Paint scrapers and hand-held knives generally have a wooden handle, and perform various operations such as cutting and scraping by gripping the handle, and in particular, The handle base is used by hitting other objects with the handle base, or by hitting the base of the handle with a hammer or the like in order to perform an original operation such as cutting or scraping. For this reason, a hitting portion is formed at the base of the handle in the hand-held tool. The structure of the hitting part is to attach a ring-shaped wig to a wooden handle as seen in general chisels, or to attach a thick metal as seen in knives (especially electric knives). This is related to a hand-held tool to be mounted as a hitting part.The conventional thick-metal hitting part is integrated with the tool body by directly welding thick metal to the base of the tool body or fastening it with screws. ing.
In addition, among the above-mentioned fastening means, those which are performed by welding, for example, when trying to form a wooden pattern so as to have the same thickness as the thickness of the thick metal, welding cannot be performed at the paragraph portion of the main body and the thick metal. Welding was performed on the outer peripheral surface of the thick metal. For this reason, finish grinding and polishing work is required at the welding location, and the strength of the welding location may be reduced depending on the degree of finishing, and the finishing work becomes extremely troublesome. Furthermore, fastening means such as screwing and tacking are locations where they are always strongly hit, and therefore have a problem in strength.

Therefore, the present invention proposes a hand-held tool having a mounting structure in which the impact portion can be easily and firmly mounted.

(Means for Solving the Problems) A hand-held tool according to the present invention includes a tool body having a handle portion formed in a flat plate shape, a striking member attached to a handle portion base end, and a wooden handle attached to the front and back of the handle portion. In a hand-held tool comprising a member, a base portion of a handle portion can be fitted to a striking member so that a concave portion is formed and fitted, and a boundary with the striking member is welded to the front and back surfaces of the handle portion, and the wooden handle member A gouge is formed at a position corresponding to the welded portion, and a wooden handle member is attached to the handle.

(Operation) Since the main body is fitted into the concave portion of the striking member, even if a strong impact is applied to the striking portion, the striking force does not act in a direction in which the two are separated from each other. Since it is stored in the gouge of the wooden handle member and cannot be visually recognized from the outside, the finishing step of the bonding portion is not required.

(Example) Next, an example of the present invention will be described.

The examples show a scraper for painting. The coating scraper is composed of a thin metal plate main body 1, a handle member 2, and a striking member 3. The tool main body 1 includes a spatula-shaped blade edge portion 11, and a handle portion 12 on which the handle member 2 is mounted. Is provided with a tack hole 13. The handle member 2 is a wooden handle which is attached to the handle 12 with a stud 21 and has a gouge 22 formed on the inner surface on the base end side. Striking member 3
Is provided with a concave portion 31 in a thick gold shape to which the tail end of the handle portion 12 can be fitted.

Thus, the tail end of the handle 12 is fitted into the recess 31 of the striking member 3, and the surface of the handle 12 and the boundary between the striking member 3 are welded.
After the two are integrated, the handle part member 2 is gripped with the stud 21
It is to be mounted on the front and back of the twelve.

Therefore, the tool body 1 and the striking member 3 are integrated, and can sufficiently withstand the striking at the striking portion and the striking portion, and the welded portion a is concealed by the gouge 22. is there.

Note that the present invention is not limited to the above-described embodiment, but is also applicable to knives and other hand tools.

(Effects of the Invention) The present invention is directed to a hand-held tool having a hitting member at a base end of a grip portion as described above, in which a concave portion in which the base end portion is fitted is formed in the hitting member. Welding both at the boundary with the part to provide sufficient strength against impact, as well as providing a gouge on the handle member to conceal the welded part, eliminating the finishing step of the welded part Thus, the manufacturing process can be simplified.
