Abstract

(57) [Summary] [Object] An object of the present invention is to provide a saw which can quickly and smoothly cut wood vertically, horizontally or diagonally without changing the blade. In a saw in which a large number of blades are arranged side by side on at least one side of a blade plate, the blade is a groove 2 having a width of about one blade from the base direction of the blade plate toward the front end direction. 1
A set of reference blade rows, in which the individual vertical saw blades 3 and the 4 to 10 horizontal saw blades 4 are arranged in this order, are repeatedly provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a saw used by a carpenter or a general household.

[0002]

[Prior art]

 The saw blade has vertical and horizontal saw blades, and the conventional saw had a vertical saw blade formed on one side of the blade body and a horizontal saw blade on one side.

[0003]

[Problems to be solved by the device]

 As described above, there are two types of conventional saw blades, one for vertical grinding and the other for horizontal grinding, each of which is formed to be suitable for vertical or horizontal grinding. That is, the horizontal saw blade cuts the timber at a slow speed while cutting the wood streak with a sharp blade, and the vertical saw blade cuts the soft part of the wood at a fast speed without cutting the streak of the wood. . As described above, since the vertical saw blade and the horizontal saw blade are formed so as to be suitable for the intended use, the use of the horizontal saw blade at the time of obliquely cutting wood has a disadvantage that it takes more time than necessary. Moreover, the use of the vertical saw blade has a drawback that the blade is caught in the streaks of wood. An object of the present invention is to provide a saw that can quickly and smoothly cut wood when it is cut diagonally.

[0004]

[Means for Solving the Problems]

 According to the configuration of the present invention, in a saw in which a large number of blades are arranged side by side on at least one side of the blade plate 1, the blades have a width of about one blade from the base direction of the blade plate toward the front end direction. It is characterized in that a set of standard blade rows in which the groove 2, one vertical grinding blade 3, and 4 to 10 horizontal grinding blades 4 are arranged in this order are repeatedly arranged.

[0005]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. This saw is provided with a blade only on one side. The blade is a groove 2 for one blade from the base direction of the blade plate 1 to the front end direction, and one longitudinal groove adjacent to the front of the groove 2. A reference blade row in which the grinding blade 3 and eight horizontal grinding blades 4 are arranged adjacent to each other in front of the grinding blade 3 are repeatedly arranged. The number of horizontal grinding blades 4 included in one set of reference blade rows is not limited to eight as in the embodiment, and may be any number in the range of 4 to 10 as described above.

[0006] The blades are not aligned with the reference blade row over the entire length thereof, and only the horizontal cutting blades are aligned near the base portion. The base horizontal grinding blade has a length of about a quarter of the total length of the blade. The present invention is not limited to the one in which only the horizontal grinding blade is provided in the vicinity of the base portion and the reference blade row is provided in other portions as in this embodiment, and the reference blade is provided over the entire length of the blade. It does not matter if there are rows.

[0007]

[Effect of device]

 The configuration of the present invention is as described above, and the blade extends from the base portion direction of the blade plate 1 toward the front end direction, and has one groove 2 having a width of about one blade, one vertical cutting blade 3, and A reference blade row in which 4 to 10 horizontal grinding blades 4 are arranged in order is repeatedly provided. Therefore, since four to ten horizontal saw blades 4 are arranged side by side, it is possible to smoothly cut wood with the horizontal saw blades 4 when cutting the wood in the lateral direction. Further, when the wood is cut in the vertical direction, it is possible to quickly cut the wood due to the presence of the vertical cutting blade 3. When cutting wood diagonally, the horizontal saw blade 4 cuts the line while the vertical saw blade 3 efficiently scoops the slightly soft part between the lines. Compared to, the wood can be cut smoothly and quickly. Further, in the present invention, the groove 2 is provided adjacent to the blade plate base of the vertical grinding blade 3 so that the groove 2 becomes a space. Therefore, during cutting of wood, there is a space for the groove 2 in front of the vertical saw blade 3, so that the vertical saw blade 3 has a better bite on the wood, and more wood can be scooped compared to the case where there is no groove. Therefore, it can be done quickly when cutting wood in the longitudinal direction. Moreover, the sawdust can be smoothly ground because the cutting dust generated during the cutting of the wood accumulates in the groove 2. As shown in the drawing, when all the blades are not used as the standard blade row and only the horizontal saw blades are arranged without providing the reference blade row on the blade near the base of the blade plate, When the blade is applied to the wood and first ground, the blade bites into the wood so smoothly that it can proceed smoothly.
