JP3061758U - File tool for circular saw - Google Patents

Abstract

(57) [Summary] The angle when using a file with a file tool for circular saws is fixed at 45 ° to 50 °, and the tool alone can also serve as a setter and can be correctly polished. The configuration is such that a horizontally long V-shaped concave portion is formed in the center of a horizontally long plate-shaped metal plate, a metal plate band portion is provided at both ends thereof, a mountain-shaped convex portion is provided above the band portion, and an annular passage is formed. The cylindrical file and the rectangular file can be inserted into and removed from the annular passage, and one end of the metal plate is used as a set-out part. When using the file, the end of the set-out part is on the side of the circular saw. Because it touches, the angle of the file can be fixed at 45 to 50 degrees,
In this configuration, the space between the V-shaped concave portion and the edge is curved to make contact with the blade portion at two points.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a convenient circular saw file that can be used both as a file and as a set-out part, can maintain a constant angle when the file is used, and can be polished correctly. It is.

[0002]

[Prior art]

 Conventionally, the circular saw file and the set-out part were separate instruments. In addition, since there was no file device to keep the angle constant when used, I applied for a utility model under the name of "file tool for circular saws" on January 17, 1995 and was registered (No. 3013698). ).

[0003]

[Problems to be solved by the invention]

 The file for the circular saw and the set-out part were inconvenient with separate tools, and the file could not be kept at an appropriate angle (45 ° to 50 °) when used. In order to make this inconvenience a convenient tool, a utility model was filed and registered on January 17, 1995 as described above. Later, I discovered that there is still a point to improve this. This was an issue.

[0004]

[Means for Solving the Problems]

 A horizontally long V-shaped concave portion is formed in the center of the horizontally long plate-shaped metal plate described in the claims, and a metal plate band portion is attached to both ends of the metal plate to insert and remove a file. One end of the plate was used as a set-out part. The file uses a round file and a square file. A round file sharpens the circular saw blade and is suitable for cutting grass, and a square file sharpens the circular saw blade and is suitable for cutting bushes. The above is the description of the device I applied for and registered. What has recently been improved is that the structure between the V-shaped recess and the edge is curved so that the blade can be properly polished by contacting the blade at two points.

[0005]

[Embodiment of the invention]

 Insert a round file or square file into the file tool of the present invention, and use it so that the circular saw is sandwiched between both legs of the set-out part.Therefore, one of the set-out parts is stably in contact with the side of the circular saw. And the angle of the file can be maintained at a certain appropriate angle (45 ° to 50 °). Even when the space between the V-shaped concave portion and the edge was curved and brought into contact with the blade portion at two points, the polishing was correctly performed.

[0006]

【Example】

 This will be described with reference to the drawings. (1) is a horizontally long plate-shaped metal plate, (2) is a horizontally long V-shaped concave portion, (3) is a metal plate band portion, (4) is a mountain-shaped convex portion, (5) is a cylindrical file, and (6) is a corner. A cylindrical file, (7) is a set-out portion, (8) is a blade portion, (9) is a circular saw, (10) is an annular passage, (11) is an angle between the file and the circular saw, and (12) is The edges, (13) and (14) are contact points.

[0007]

[Effect of the invention]

 As detailed above, it is essential that a very convenient file tool for circular saws greatly contributes to industrial development.
