Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a new plane which is an improvement of the conventional two-blade plane and is substantially configured as a one-blade plane.

[0002]

[Prior Art]

 As shown in FIG. 5, a plane that has been widely and conventionally used is provided with a plane blade 1, a plane blade 2 that specially cuts wood, and a back metal blade 3 that prevents inversion, separately from the plane 1. While a push-in groove 5 for pushing the plane blade 2 into the instep hole 4 of No. 1 is obliquely provided, a metal shaft member 6 is horizontally provided in the instep hole 4 and a hook is provided between the shaft member 6 and the indentation groove 5. The blade 2 and the back metal blade 3 are mounted in a superposed state.

[0003]

[Problems to be solved by the device]

 Therefore, the conventional plane requires not only two large plane blades 2 and back metal blades 3 which are independent of each other, but also a metal shaft member 6 for fixing the two blades 2 and 3 in the instep hole 4. Therefore, it is necessary to form a hole 7 for laterally arranging the shaft member 6 in the hoisting base 1 and then to close the hole 7 later. Needless to say, the processing is troublesome, but in particular, the use thereof has the following remarkable problems.

That is, as a condition for successfully using a plane, it has long been mentioned that the plane edges of the plane blade 2 and the back metal blade 3 are shifted by about 0.3 to 0.5 mm and are aligned back and forth. There is. The reason for this is that if it is more or less than this, the barrage cannot be effectively stopped. However, in the conventional two-blade plane described above, when the two blades 2 and 3 are to be aligned, generally, the head of the back metal blade 3 is looked into while looking into the instep 4 of the plane base 1. Needless to say, it must be done by striking it, which makes the work complicated, but there was no way to make adjustments except by relying on the intuition of the user. For this reason, if you are an expert with a high degree of skill, it is extremely difficult for an amateur who does not have such a skill to make a fine blade alignment between the plane blade 2 and the back metal blade 3, which is very difficult. It is a major obstacle to use.

In addition, in actual use, in addition to the above-mentioned blade alignment, it is also important how much the blade edge of the plane blade 2 is projected from the blade opening of the plane base 1, but the conventional two-blade plane In this case, simply looking at the blade edge of the plane blade 2 from the base side of the plane base 1 and relying on the amount of protrusion to confirm and adjust it, even in this case, It is very difficult for an expert who has a skilled technique to accurately check and adjust the amount of protrusion of the blade tip protruding from the blade, even for an amateur who does not have such skill.

[0006]

[Means for Solving the Problems]

 Thus, the present invention was developed in order to effectively solve the problem of the conventional two-blade plane, and is composed of a plane and one plane, and the plane has the above-mentioned 1 A push-in groove for pushing in a piece of plane is obliquely provided, and the plane has a blade portion integrally formed at the tip edge of one side surface, while a concave step portion is provided at the tip portion of the other side surface in the concave step portion. A separately molded blade having a blade is fixed, and the blade of the blade on the other side and the blade on the one side are used as a plane blade and a back metal blade. The blade and the back metal blade are aligned with each other by the dimension difference between the concave step portion and the blade body, and the blade portion used as a plane blade is provided with a protrusion amount confirmation mark.

[0007]

[Action]

 Therefore, according to the present invention, compared with the conventional two-blade plane, two independent blades and a shaft material for superposing and fixing the blades are not required, so that the structure is simplified. Of course, there is an advantage that it can be done, but in particular, a structure in which a concave step portion is provided at the tip of the other side surface of the hook and a separately molded blade body having a blade portion is fixed in the concave step portion. Therefore, when the blade of the blade is used as a plane blade, or conversely as a back metal blade, it is necessary for the dimensions of the recessed step and blade when manufacturing. It is possible to automatically adjust the blade with the blade formed on the one side of the plane, just by making a dimensional difference. It is possible to reliably obtain the ideal blade alignment between the plane blade and the back metal blade. Also, since the blade used as a plane blade has a protrusion amount confirmation mark, when confirming the protrusion amount of the plane blade edge from the plane base, the blade edge should be projected and retracted from the blade edge. By using this confirmation mark during the work, it is possible to rationally check the protruding amount of the blade and always adjust the blade to the ideal protruding amount.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail with reference to an illustrated embodiment. The plane according to this example is different from the conventional two-blade plane described above, as shown in FIGS. Specifically, the plane itself is composed of a plane 11 formed of oak and the like, and one metal plane 12 and the former plane 11 has the above-mentioned one plane in the hole 13 for the former plane 11. Pushing the body 12 The push groove 14 is obliquely provided, and the blade 12 of the latter is integrally formed with the blade portion 12a at the tip edge of one side surface thereof, while the plurality of magnets 16 are provided at the tip portion of the other side surface thereof. By positively providing the recessed step portion 15 in which is embedded, the separately formed metal blade body 17 having the blade portion 17a is fixed in the recessed step portion 15 through the magnet 16 so that As shown in, the blade portions 12a and 17a which are in back-to-back state are provided at the front end edges on both sides of this one body 12 together. It is obtained without the structure to be present in.

Therefore, under such a configuration, at the time of manufacturing, a dimensional difference required for blade alignment is provided with respect to the height dimension L1 of the concave step portion 15 and the height dimension L2 of the blade body 17. Only by doing so, the blades 12a and 17a existing on both sides of one plane 12 can be automatically and accurately aligned with each other. To explain this in detail, in the present embodiment, the blade portion 17a of the blade body 17 is used as a plane blade, and the blade portion 12a integrally formed on the plane body 12 side is used as a back metal blade. Based on the premise that the height dimension L1 of the concave step portion 15 is set to be about 0.3 to 0.5 mm shorter than the height dimension L2 of the blade body 17, By simply fixing the body 17 in the concave step portion 15, as shown in the drawing, the blade edge of the blade body 17 can be shifted to outside of the above-mentioned 0.3 to 0.5 mm to obtain an ideal blade alignment state. And On the contrary, when the blade portion 17a of the blade body 17 is used as a back metal blade, the height dimension L1 of the recessed step portion 15 is about 0.3 to 0 smaller than the height dimension L2 of the blade body 17. If it is set to be 0.5 mm long, the blade edge of the blade portion 12a used as a plane blade is ideally in a state where the blade edge is displaced from 0.3 to 0.5 mm as in the above case. Will be obtained.

In addition, in this embodiment, as shown in FIG. 2, in particular, a configuration is adopted in which a protrusion amount confirmation mark 18 is provided on the surface of the blade portion 17a of the blade body 17 used as a plane blade. However, when applying this mark 18, a paint such as red that is easily noticeable is directly applied to the surface in the vicinity of the cutting edge, or specifically, although not shown, the surface of the cutting edge 17a. It is assumed that a continuous dent portion is defined and the paint is applied in the dent portion. On the contrary, when the integrally formed blade portion 12a of the hook body 12 is used as a plane blade, the protrusion amount confirmation mark 18 is formed on the surface of the blade portion 12a by the above method.

Therefore, in the plane of this embodiment, if the blade body 17 is fixed to the concave step portion 15 of the plane body 12 and the plane body 12 is pushed into the pushing groove 14, As shown in FIG. 4, one plane 12 having a plane blade and a back metal blade at the same time can be securely attached to the plane base 11 without using a metal shaft material such as the above. Moreover, in this mounted state, by fixing the blade body 17 in the concave step portion 15 of the hook body 12 through the magnet 16, the dimensional difference between the both 15 and 17 is used as a plane blade. The blade portion 17a of the blade body 17 and the blade portion 12a on the side of the hook 12 used as the back metal blade are placed in an ideal blade alignment state that is offset by 0.3 to 0.5 mm. Therefore, when using it, there is no need to rely on delicate adjustment as in the past, and the biggest obstacle in the use of the conventional two-blade plane can be solved.

Therefore, after that, the amount of protrusion of the blade tip from the blade opening 13a of the plane base 11 may be adjusted. Since the protruding amount confirmation mark 18 is provided, if the protruding amount of the blade tip is checked using this confirmation mark 18 during the work of retracting the blade tip from the blade opening 13a, the ideal protrusion of the blade tip will always be obtained. It is possible to adjust the amount very reasonably. In particular, when using the confirmation mark 18, if the front edge of the mark 18 comes out of the blade opening 13a, it is not a standard for cutting wood, and if the rear edge of the mark 18 is completely outside, the cutting edge is too far out. If the intermediate area between the rear edge and the front edge is used as a guide for the cutting thickness of the wood, even an amateur can properly cut the wood according to the purpose.

Further, when adjusting the amount of protrusion of the blade edge of the plane blade, even if the plane body 12 is moved up and down in the pushing groove 14, the blade body 17 itself has the same width as the other side surface of the plane body 12. First of all, since it is securely fixed in the concave step portion 15 by the magnetic attraction force of the magnet 16, there is no fear that the blade body 17 is inadvertently moved or dropped in the concave step portion 15. .. Further, in the present embodiment, even if the blade body 17 is separately required, the blade body 17 is absorbed by the side of the plane body 12 and substantially constitutes a plane blade plane. Therefore, as compared with the conventional two-blade plane, as shown in the drawing, the blade opening 13a of the plane base 11 can be made as small as possible. It will be further promoted.

In the above embodiment, the blade body 17 is fixed to the concave step portion 15 via the magnet 16 in consideration of workability of assembling, but the present invention is not limited to this. The blade body 17 is not limited to this, and may be integrally fixed in the recessed step portion 15 using an adhesive or other known means, depending on the implementation.

[0015]

[Effect of the device]

 As described above, the present invention can be structurally simplified by adopting the above-mentioned structure as compared with the conventional two-blade plane, but in particular, the concave step is formed on the tip of the other side surface of the plane. By adopting a structure in which a separately formed blade body having a blade portion is provided in the concave step portion is adopted, even when the blade portion of the blade body is used as a plane blade, on the contrary, the back metal blade Even if it is used as a blade, it is necessary to make a necessary dimensional difference between the dimensions of the concave step and the dimensions of the blade at the time of manufacture, and the blade alignment with the blade formed on one side of the plane Since it can be automatically performed, the ideal blade alignment state of the plane blade and the back metal blade can always be immediately obtained regardless of who uses it, without relying on intuition. Also, because the blade used as a plane blade has a protrusion amount confirmation mark, this confirmation mark can also be used when adjusting the protrusion amount of the blade tip from the blade of the plane. By reasonably checking the protruding amount of the blade edge, it is possible to always set the blade edge to the ideal protruding amount. In any case, the present invention is suitable for use in the conventional two-blade plane. By eliminating the problem of, it became possible to guarantee that even an amateur could cut wood as much as an expert.
