There are two types of glass cutters: hand-held ones that have a rod-shaped handle, and glass cutters that move one or more cutting blades horizontally using a motor or the like. In either case, a disc-shaped cutting blade is rotatably attached to the holder via a shaft. Therefore, the cutting blade must have a hole in its center for the shaft to pass through, and when installing it in a holder, the shaft must be inserted into the hole in the cutting blade and then installed in the holder. However, since the cutting blade has a small diameter of about 3 mm,
These tasks are quite troublesome. Additionally, due to the difference in diameter between the shaft and the shaft hole of the cutting blade, and the difference in the diameter between the shaft and the hole in the holder, problems such as the cutting blade being slightly inclined during use occur, and such inclined cutting When a cut line is made with a blade, the cut line is meandering. If the cut line is meandering, the glass may not be broken along the cut line when the glass is broken, and the edge of the broken glass may become sloped, reducing the accuracy of the cut. .

The figure shows another example of a holder, in which shaft holes 6, 6 are provided at both ends of a plate or rod that can be elastically deformed, such as a plate spring, as shown in Figs. Alternatively, the rod is bent into a U-shape or V-shape, and the distance between the opposing parts is the slit part 5 of the holder 4.
It has a bearing material 7 whose width is larger than that of the bearing material 7. Then, as shown in FIG. 7, the bearing material 7 with the shaft parts 3, 3 of the cutting blade 1 inserted into the shaft holes 6, 6 is pushed into the slit part 5, and the cutting blade 1 is inserted through the bearing material 7. is holder 4
It was installed on the Furthermore, the slit portion 5
Providing an adjusting screw 8 that passes through one side wall and applying pressure to the bearing material 7 is suitable for preventing the bearing material 7 from slipping off, and also prevents the contact between the shaft hole 6 and the shaft portion 3. The state can be adjusted arbitrarily, and it is suitable for making the rotation of the cutting blade 1 smoother and eliminating the inclination of the cutting blade 1.

Also when attaching the cutting blade 1 to the holder 4,
Since the cutting blade 1 itself has the shaft portion 3, the installation work is easy. Since the shaft portion 3 has a conical shape, it can be stably attached to the holder 4.
For example, when the tip of the shaft portion 3 is sharpened as in the examples shown in FIGS. 1 to 4, the shaft hole 6 provided in the holder 4 is made into a conical recess, and If the inclination angle of the surface is made larger than the inclination angle of the shaft part 3, only the tip of the shaft part 3 is supported in a dotted manner in the inner part of the shaft hole 6, so that when the cutting blade 1 rotates, It is easy to reduce friction and eliminate its slope.

As shown in FIG. 7, if the shaft hole 6 is made to have the same diameter over its entire length, its mouth edge will be linear and only contact the shaft portion 3, which will reduce friction when the cutting blade 1 rotates. Can be made smaller. Further, as shown in FIG. 11, the shaft hole 6 of the holder 4 is formed into a conical shape, and a hole whose entire length in the longitudinal direction is approximately circular in diameter is provided continuously at the inner part thereof. If the angle of the circumferential surface of the conical part of the shaft hole 6 is made larger than the inclination angle of the shaft part 3, the ring-shaped contact point between the conical part of the shaft hole 6 and the hole continuous thereto, A part of the is supported linearly. Therefore, in this example as well, the contact between the shaft portion 3 and the holder 4 is linear, and the cutting blade 1 can be rotated smoothly and stably.

第7〜9図と第11図の例では、軸孔6は凹部

すべてのものが取付け可能である。
In the examples shown in FIGS. 7-9 and 11, the shaft hole 6 may be a recess or a through hole, and the cutting blade 1 can be attached to all of the examples shown in FIGS. 1-5.

第6図のように、軸孔6の内周面のほぼ全体に

The holder 4 may be any holder as long as it can support the shaft parts 3, 3 of the cutting blade 1, but as in the examples shown in Figs. Alternatively, in the example shown in FIG. 6, one part of the shaft hole 6 of the holder 4 is separated, and it is attached with an adjusting screw 10 with a spring 9 such as a plate interposed therebetween, so that the opposite part of the slit part 5 is separated. By making it possible to change the spacing between the surfaces, the contact state of the cutting blade 1 with the bearing material 7 or the holder 4 can be easily adjusted, and when the part of the holder 4 in contact with the shaft 3 becomes worn, , by tightening the adjustment screws 8 and 10,
It is possible to improve the stability of the cutting edge 1 and is more suitable.

As mentioned above, in the cutting blade of the present invention, the conical or truncated conical shaft portions 3 formed on both sides of the ring-shaped cutting edge 2 are directly inserted into the shaft hole 6 of the holder 4, etc. The attachment of the cutting blade 1 to the holder 4 can be facilitated, and the contact area between the shaft portion 3 and the shaft hole 6 of the holder 4 or the like can be reduced, so that the rotation of the cutting blade 1 can be made smooth. In addition, since the inclination of the cutting blade 1 itself can be almost eliminated, when a cut line is made in the glass, the cut line always becomes a straight line, and the problem caused by meandering of the cut line can be solved.

In addition, since the conical or truncated conical shaft portion 3 is integrally provided on both sides of the ring-shaped cutting edge 2, the shaft hole of the cutting blade 1 is not required, and the shaft portion 3 has a well-known hole for shaft insertion, and supports it. It is possible to make the outer diameter of the cutting edge 2 smaller than that of the cutting blade through which the shaft is inserted. Therefore, when the cutting edge 2 is pressed against the glass in order to make a score in the glass, the length of the cutting edge 2 that comes into contact with the glass is shortened. That is, when the cutting edge 2 is pressed against the glass, the force can be applied intensively to the glass. Therefore, when making a cut of the same depth, the cut can be made with a lower load than a known cutting blade, so the rotation of the cutting blade 1 can be made smoother, and the cut on the glass can be made more easily. It is possible to make cuts with high precision, and it is also possible to make cuts without straining even thin glass sheets.
