Summary of the Invention
Problems to be Solved by the Invention
[0005] The conventional depression processing with a round plane requires skillful work because of the thin plate thickness and is difficult to perform easily. Further, in the manufacturing method of Patent Document 1, various mechanical facilities for feeding a planing board into a wire brush roll are required, and the installation thereof is extremely troublesome.
[0006] Therefore, the present invention was created in view of the above-mentioned conventional circumstances, and aims to provide a decorative sawn board having a textured surface, a processing method for the same, and a processing tool, which does not require the installation of troublesome mechanical equipment and allows for the formation of recessed grooves on the surface of the sawn board using simple handheld processing tools, and moreover, produces a sawn board with an aesthetically pleasing finish. [Means for solving the problem]
[0007] To solve the above-mentioned problems, the present invention provides a decorative sawn board having an uneven pattern, which is formed by cutting the surface of the sawn board T by moving a processing tool 1 equipped with a cutting part 4 in a pressure-contact state, thereby creating a shallow recessed pattern that forms recessed grooves T1. The processing tool 1 is characterized in that a sub-handle part 3 is connected perpendicularly to the main handle part 2 at the tip of the main handle part 2 for operating the processing tool 1 itself, and a flat circular cutting part 4 is provided located directly below the sub-handle part 3, with its lower end formed into a sharp cutting blade 5. Furthermore, the present invention relates to a method for processing decorative sawn boards having an uneven pattern, wherein a shallow recessed uneven pattern, which forms a recessed groove T1, is processed and formed by cutting by moving a processing tool 1 equipped with a cutting portion 4 in a pressed state against the surface of the sawn board T, and the processing tool 1 is characterized in that a sub-handle portion 3 is connected perpendicularly to the main handle portion 2 at the tip of a main handle portion 2 for operating the processing tool 1 itself, and a flat circular cutting portion 4 is provided located directly below the sub-handle portion 3, with its lower end formed into a sharp cutting blade 5. Furthermore, the processing tool used in the processing method for a decorative sawn board having an uneven pattern according to the present invention is characterized by comprising: a main handle portion 2 that is gripped with the fingers and used to set the processing posture of the processing tool 1 itself; a sub-handle portion 3 connected perpendicularly to the main handle portion 2 at the tip of the main handle portion 2; and a cutting portion 4 located directly below the sub-handle portion 3, which is formed in a planar circular shape with a groove cross-section and whose lower edge is a sharp cutting blade 5.
[0008] In the decorative sawn board having an uneven pattern, a processing method therefor, and a processing tool according to the present invention, the cutting blade 5 of the cutting section 4 is moved in a press-fit state while being gripped by the main handle section 2 and the sub-handle section 3, thereby forming shallow recessed grooves T1 on the surface of the sawn board T. The cutting blade 5 is circular when viewed from a plane, and when in contact with the surface of the sawn board T at a predetermined angle, it processes recessed grooves T1 that exhibit different depths and lengths in an arc shape. By setting the start and end positions, various recessed grooves T1 can be formed at arbitrary positions on the surface of the sawn board T, resulting in a variety of uneven patterns. The processing method, performed by gripping the main handle 2 and the sub-handle 3 respectively, allows for the adjustment of any predetermined angle when pressing against the sawn plate T. This, combined with the fact that it is gripped by the fingers of both hands, makes it possible to form various types of recessed grooves T1 with different depths and lengths in a simple operation, without requiring any special skills. [Effects of the Invention]
[0009] As described above, the present invention is configured such that by gripping the main handle portion 2 and the sub-handle portion 3 of the processing tool 1 with the fingers and pressing the cutting portion 4 against the surface of the sawn board T at a predetermined angle and moving it, recessed grooves can be processed and formed on the surface of the sawn board T. Moreover, since the processing tool 1 is handheld, it is possible to apply a textured pattern to the surface of the sawn board T with simple work without requiring any special skills.
[0010] In other words, this is because the processing tool 1 in the present invention has a main handle portion 2 to which a sub-handle portion 3 is connected, and a flat circular cutting portion 4 with a sharp cutting blade 5 at its lower end is provided directly below the sub-handle portion 3. As a result, the formation of recessed grooves T1 on the surface of the sawn plate T can be efficiently carried out using the easy-to-handle processing tool 1.
[0011] Furthermore, the reference numerals appended in the sections on the means for solving the above problems and the effects of the invention are provided to facilitate reference with the parts of the components shown in the drawings. The present invention is not limited to the structure, shape, etc., indicated by these descriptions or the reference numerals in the drawings. [Brief explanation of the drawing]
[0012] [Figure 1] This is a perspective view of a workpiece illustrating one embodiment for carrying out the present invention. [Figure 2] This is also a cross-section of the same object. [Figure 3] This is also a perspective view of the usage state. [Figure 4] This is also a cross-sectional view of a decorative veneer. [Figure 5] These are product photos of two examples of decorative veneer. [Modes for carrying out the invention]
[0013] Hereinafter, with reference to the drawings, one embodiment for carrying out the present invention will be described. Reference numeral 1 in the drawings indicates a work tool, and by cutting the surface of the sawn plate T with this work tool 1, a recess exhibiting an arc shape in cross-section is formed.
[0014] As shown in the figure, the tool 1 itself comprises a main handle portion 2 that is held with the fingers and used to set the overall position of the tool 1 during machining, a sub-handle portion 3 connected perpendicularly to the main handle portion 2 at the tip of the main handle portion 2, and a cutting portion 4 located directly below the sub-handle portion 3, which has a planar circular shape with a grooved cross-section and a sharp cutting edge 5 at its lower end.
[0015] As shown in Figure 2, the main handle section 2 and the sub-handle section 3 are formed from, for example, pipe-shaped members to achieve both robustness and lightness. The operator holds the main handle section 2 with one hand and the sub-handle section 3 with the other hand to perform the work, and the length of the main handle section 2 is set to, for example, 250 to 350 mm so that it can be used with both hands.
[0016] The auxiliary handle portion 3 is designed to be firmly gripped by the fingers so that it can be pressed against the sawn board T with a predetermined cutting pressure against the cutting portion 4, and its length is formed to be approximately 80 to 120 mm.
[0017] In the illustration, the cutting portion 4 is supported and connected directly below the sub-handle portion 3 by a connecting portion 6 formed in an L-shape when viewed from the side, and the cutting portion 4 itself is positioned in front of the sub-handle portion 3 when viewed from the side or the plane. The cutting portion 4 is fixed to the bottom surface portion of this L-shaped connecting portion 6, for example, by screwing.
[0018] The cutting portion 4 itself is formed in a groove shape with a cross-section of, for example, about 50 mm in diameter and has a height of, for example, about 10 to 15 mm. And at the peripheral edge which is the lower end, it is formed on a cutting edge 5 that is sharply machined in cross-section, and by moving it in a pressure contact state at a predetermined angle with respect to the surface of the lathe plate T, a shallow-bottomed recessed groove T1 corresponding to the arc shape of the cutting edge 5 can be processed and formed.
[0019] The pressure contact angle, pressure contact strength, etc. of the cutting portion 4 with respect to the lathe plate T, together with the undulation and direction change of the main handle portion 2 held by one finger, etc., and the adjustment of the magnitude of the pressing force on the sub-handle portion 3 held by the other finger, that is, by appropriately setting and operating the posture modes with respect to the main handle portion 2 and the sub-handle portion 3, various uneven recessed grooves T1 with different lengths, depths, widths, directions, arrangement forms, etc. of the recessed groove T1 can be processed and formed.
[0020] Next, the procedure for processing and forming a recessed groove T1 that becomes a recessed unevenness on the lathe plate T by this cutting tool 1 will be described. As shown in FIG. 3, with respect to the surface of the lathe plate T fixed and maintained by a predetermined method, hold the main handle portion 2 with one finger and the sub-handle portion 3 with the other finger, and press the cutting portion 4 against the surface of the lathe plate T at a predetermined angle. Then, while in the pressed state, the cutting tool 1 can be moved, for example, along the grain, and a shallow-bottomed recessed groove T1 is processed and formed on the surface of the lathe plate T as it moves.
[0021] By repeating such cutting operations, recessed grooves T1 with different lengths, depths, widths, directions, arrangement forms, etc. are processed and formed at appropriate intervals on the surface of the lathe plate T, and an uneven and natural-looking decorative pattern is applied (see FIG. 4).
