Description

  The present invention applies the attractiveness of a ferromagnetic steel saw and the magnetic force of a magnet to cut the accuracy of the cutting angle, which is the most bottleneck when cutting materials such as wood, without requiring skill. The present invention relates to an angle holding method and configuration for sawing that can be easily and accurately cut.

  Conventionally, when cutting materials such as wood using an artificial manual saw, the cutting accuracy is determined by the skill and skill of the person, and when using a simple angle ruler, etc. However, it was just a guideline and did not assist in copying the angle by a strong action.

  In other words, in manual saw cutting by human beings, the person's cutting skill and dexterity were conventional basic techniques.

Problems to be solved by the invention

If we describe the conventional issues,
(B) Maintaining the cutting angle accuracy is the most difficult task for amateurs to perform manual sawing, and there are many cases in which sharp or obtuse angles are obtained even when aiming at right-angle cutting when cutting materials such as wood. This was a problem because there was a lot of inaccurate cutting work, such as do-it-yourself carpenters, especially today.
(B) In some cases, a simple angle ruler based on a cutting material may be used, but it is only an indication of the cutting angle and does not assist the copying of the saw angle, and is not an effective means of compensating for the lack of skill.

Means for solving the problem

Now, if you explain the method and configuration to solve the problem,
(A) In claim 1, the scanning angle mechanism of the ferromagnetic steel saw 1 is constituted by the surface plate 4 and the magnet 2, and the cutting force of the cutting material 5 is cut by the ferromagnetic material by the attractive force of the magnet 2. A manual cutting method in which the cutting material 5 is cut by a back-and-forth sliding operation with a small frictional force while the side surface of a steel saw 1 is attracted by the suction plane 3 of the magnet 2 to maintain the angle.
(B) Claim 2 has a lubricating protective cover 6 which is a thin wear-resistant material for protecting the saw 1 on the attracting plane 3 of the magnet 2 to minimize the friction caused by the cutting action and minimizing the magnetization of the saw 1. Configuration.
(C) The third aspect of the present invention is a basic structure in which the base plate 4 of the base abutting portion set on the cutting material 5 has the magnet 2 as the cutting angle copying portion of the saw 1 and the contact surface of the magnet 2 with the side surface of the saw 1 Is a structure having a smooth suction plane 3 structure.

Action

Next, the operation of the present invention will be described.
With respect to the first aspect, a highly accurate angle is maintained while maintaining a stable scanning angle by reciprocating back and forth while attracting the side surface of the ferromagnetic steel saw 1 to the attraction plane 3 of the magnet 2 set to a necessary cutting angle. It is the effect | action cut | disconnected by.

  According to the second aspect of the present invention, the lubrication protection cover 6 is provided on the attraction plane 3 of the magnet 2 to reduce the frictional resistance, wear, breakage, and magnetization due to the friction of the saw 1 as much as possible.

  According to the third aspect of the present invention, in the cutting angle copying mechanism comprising the surface plate 4 set on the cutting material 5 and the attraction plane 3 of the magnet 2, the cutting angle of the saw 1 is stably maintained and the reciprocating operation is performed with little friction. is there.

As a specific example,
(A) A bottom stopper 7 for fixing to the cutting material 5 is provided on the lower side of the front portion of the surface plate 4, and an angle adjusting unit 8 for maintaining and adjusting the angle between the magnet 2 and the surface plate 4 is provided between the surface plate 4 and the magnet 2. Provide at the joint.
(B) The back surface of the surface plate 4 has a shift preventing portion with the cutting material 5.
(C) A concave right angle holding frame 9 for fitting the magnet 2 to both ends of the surface plate 4 and maintaining it at a right angle and a concave 45 degree holding frame 10 for maintaining it at 45 degrees are included. Is detachable by magnetic force.
(D) A moving roller 11 for copying the cutting material 5 is provided at the front of the surface plate 4.
(E) Apply a lubricant to the attraction plane 3 of the magnet 2.
(F) A gap is provided so that the lower side of the magnet 2 is slightly raised from the surface plate 4 so that the blade portion of the saw 1 does not contact the magnet 2.

effect

  The angle holding method and configuration of the saw cutting using the magnet of the present invention does not require skill in saw cutting skills, and even a dexterous person or woman can easily cut with high accuracy. The loss of correction and material costs due to poor cutting accuracy can be saved, and many amateur carpenters are born through the promotion of skill removal, and the work of the family such as Sunday carpenters is promoted, making it bright, fun, healthy and creative. It greatly contributes to the creation of a prosperous society.
