Abstract

PURPOSE:To enable a saw blade to be surely attached to the back metal by forming a notched part on the upper edge part of the back metal, and forming a rising- protrusion on the base upper end part of the saw blade and a projection extended in the lateral direction for allowing them to come there into, and then permitting the lower edge part of the projection to come into contact with the upper edge part of the back metal. CONSTITUTION:A saw main body 1 comprises a handle 3 attached with a back metal 4 in its tip end part and a saw blade 2 to be attached to the tip end part of the handle 3. The saw handle 3 has the back metal 4 in its tip end part and, by curve-forming a metal plate into a converted U-shape, the back metal 4 can insertion-hold the saw blade 2 there between and, on the folded part 9 of the upper edge part thereof, a notched part 5 is formed. On the other hand, the saw blade 2 is formed, at the thickness capable of being inserted into the cavity in the back metal 4, with a protrusion 7 disposed in a rising manner on the base upper end part thereof and a projection 6 extended in the lateral direction and, in the case of engaging the saw blade 2, the protrusion 7 is brought into the notched part 5 formed on the back metal 4 and then the lower edge part 8 of the projection 6 is put into contact with the upper edge part of the back metal 4.

Conventional saws with replaceable blades of this type were manufactured in 1930.
As described in Utility Model Publication No. 1674 of 2003 or Utility Model Publication No. 26724 of 1957, a back metal bent in a "U" shape is attached to the tip of the handle, and the inside of the back metal is attached to the tip of the handle. The hook part has a structure in which the stop part is arranged across the part, while the hook part forms a matching concave part at the base of the saw blade, and the engagement between the handle and the saw blade is achieved by placing the catch part in the stop part of the saw blade. The majority of blades are constructed in such a way that the recesses of the blades are aligned.

[Configuration (Means for Solving the Problems, Effects) The present invention relates to a method for engaging a saw blade in a replaceable blade saw, and the upper side of the back metal is bent so as to be able to sandwich the saw blade. At the same time, a notch is formed on the upper end of the base of the saw blade, and a raised protrusion and a protrusion extending laterally are formed on the back metal when the saw blade is engaged. In addition, the lower side of the protrusion can be brought into contact with the upper side of the back metal, thereby simplifying the overall configuration of the back metal. It is.

(Example) The method of engaging the saw blade according to the present invention will be explained based on the drawings. As shown in FIGS. and a saw blade 2 attached to the tip of the handle 3. When the saw blade is engaged with the handle, a notch 5 formed on the upper side of the back metal 4 is used.
This can be done by inserting the protrusion 7 formed at the upper end of the base of the saw blade 2 and then rotating the entire saw blade 2 upward.

That is, the saw handle 3 is as shown in FIGS. 1 to 4.
It has a back metal plate 4 at its tip, and the metal plate is bent into a reverse rTJJ shape so that the saw blade 2 can be inserted and held therein. In addition, a notch 5 is formed in the bent part 9 at the upper side, and the saw blade 2 has a thickness that allows it to be inserted into the gap in the back metal 4, and a cutout 5 is formed in the lower part of the saw blade 2. The saw blade 2 is made of a steel material in which saw teeth are arranged, and has a protrusion 7 arranged in an upright manner and a protrusion 6 extending laterally at the upper end of the base. This can be done by inserting the protrusion 7 into the notch 5 formed in the back metal 4 and bringing the lower side 8 of the protrusion 6 into contact with the upper side of the back metal 4. This is the result.

In other words, when the saw blade hook is configured to form a stop inside the back plate as seen in the conventional structure, a separate process is required to attach the stop.
The production cost of the back plate is high, and if a thin replacement blade is used, a slight contact sound will be generated between the saw blade and the back plate during the cutting operation. If this method is adopted, there is no need to form a separate latching part on the back plate, and the manufacturing cost of the back plate can be reduced. As a result of the lower end portion of the protruding portion 6 coming into contact with the upper piece portion 9 of the back metal in the front and rear portions, there is an advantage that generation of unpleasant contact sounds can be prevented.
