を占めているのである。In the case of this type of conventional blade-type saw,
As in the device described in Utility Model Publication No. 1674 in 1975 or Utility Model Publication No. 26724 in 1957, a back metal bent into a `` U '' shape is attached to the tip of the handle, and On the other hand, while the hooking portion is arranged in the form of a bridge, the hooking recess is formed at the base of the saw blade,
In most cases, the handle is engaged with the saw blade by engaging the recess of the saw blade with the retaining portion of the backing metal.

があるのである。(Problems to be Solved by the Invention) However, in the case where the engagement of the replacement blade in such a replacement blade type saw is performed by such a method, when manufacturing the back metal, the saw blade is placed at a predetermined position inside the back metal. A blade latch must be formed, which increases the cost of manufacturing the back metal, and when using a thin replacement blade, generates a slight contact noise between the saw blade and the back metal during the cutting operation. There is a problem.
この発明は、従来の構成のものにみられたこのような
問題点を解決しようとするものである。The present invention is to solve such a problem in the conventional configuration.
［構成］ （課題を解決するための手段、作用） この発明は、替え刃式鋸における鋸刃の係合方法に関

の構成のシンプル化を図ろうとするものである。[Structure] (Means for Solving the Problems, Function) The present invention relates to a method of engaging a saw blade in a replaceable saw, and an upper side portion of a back metal bent and formed so that the saw blade can be sandwiched. On the other hand, a notch is formed at the upper end of the saw blade, and a protruding protrusion and a laterally extending protrusion are formed at the upper end of the saw blade. When the saw blade is engaged, the protrusion is formed on the back metal. To be engaged with the upper edge of the backing metal by making the lower edge of the projection abut against the upper edge of the backing metal, thereby simplifying the configuration of the entire backing metal. It is.

とによって行い得る構成となっているのである。(Embodiment) A method for engaging a saw blade according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, a saw body 1 has a handle 3 having a back metal 4 attached to a tip end thereof. 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 in the upper side of the back metal 4 has a base portion of the saw blade 2. After the projection 7 formed on the upper end is inserted, the saw blade 2 can be rotated upward to rotate the entire saw blade 2 upward.

方法によって行い得る構成となっているのである。That is, as shown in FIG. 1 to FIG. 4, the saw handle 3 has a configuration in which a back metal 4 is provided at the tip thereof, and the back metal 4 forms a metal plate in an inverted “U” shape. By bending and forming, the saw blade 2 can be inserted and clamped, and the notch 5 is formed in the bent portion 9 on the upper side thereof. 2 is a thickness that can be inserted into the gap in the back metal 4;
This is achieved by a steel material having saw teeth arranged below it, and a protrusion 7 arranged in a rising shape and a laterally extending protrusion 6 are formed at the upper end of the base. When the saw blade 2 is engaged, the projection 7 is
The notch 5 is formed in the notch 5 and the lower side 8 of the protrusion 6 is brought into contact with the upper side of the spine 4.
［効果］ （発明の効果） この発明に係る替え刃式鋸の鋸刃係合方法は、上記の
ような構成であって、背金の形成が容易になるととも
に、確実な係合を行え得るという利点があるのである。[Effects] (Effects of the Invention) The method for engaging a saw blade of a replaceable blade saw according to the present invention has the above-described configuration, which facilitates formation of a backing metal and ensures reliable engagement. There is an advantage that.

In the case where is adopted, it is not necessary to form a separate latching portion on the back metal, and the manufacturing cost of the back metal can be reduced. Furthermore, as a result of the lower end of the protruding portion 6 being in contact with the upper piece 9 of the back metal, there is an advantage that generation of unpleasant contact noise can be prevented.
