[0017]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The ruler includes a contact plate 2 that slides a workpiece W such as a gypsum board or wood by bringing a flat contact surface 1 into contact with the workpiece W, and a sliding plate perpendicular to the contact surface 1. A linear sliding rod 3 provided so as to be able to move and appear, a blade 4 provided to project downward from the distal end of the sliding rod 3, and the blade 4 is attached to the sliding rod 3. And fixing means 5 for fixing. The sliding rod 3 is provided so as to be slidable by being fitted into a through hole 6 formed substantially at the center of the contact surface 1. It is inserted and attached to the hole 7. The vertical hole 7 has a slit shape, and its longitudinal direction is provided slightly inclined with respect to the abutting surface 1 from parallel. That is, the starting end 13B, which is the side that comes into contact with the workpiece W at the beginning of the blade edge 13A of the blade body 4, is brought into contact with the end side 13C, which is the side away from the workpiece W at the end of the blade edge 13A. The blade body 4 is provided to be slightly inclined from the contact surface 1 so as to be separated from the surface 1. The fixing means 5 of the blade body 4 is provided by screwing the screw shaft 8 from the front end face of the sliding rod 3 through the female screwed plate 9 and pressing the front end 8A against one side of the blade body 4. Can be fixed. Similarly, a screw shaft 10 is screwed into an end surface of the contact plate 2 orthogonal to the contact surface 1 via a female threaded plate 11, and the tip of the screw shaft 10 is pressed against the sliding rod 3 via a metal plate 12. The sliding rod 3 can be fixed.

Further, the blade body 4 is a part of a continuous blade body 4A (trade name: OLFA, trade name: Campus, trade name: NT Cutter, etc.) in which a plurality of blade bodies 4 are continuously formed through a separating groove 13. The cutting groove 13 is provided obliquely with respect to the blade edge 13A formed on the edge of the continuous blade body 4A in the longitudinal direction X, and the intersection of the groove 13 and the blade edge 13A is sharpened. Is formed. In the embodiment, the two blades 4 are integrally mounted. A safety cover 14 is provided along the blade body 4. The safety cover 14 has a shape slightly larger in the vertical direction than the blade body 4, and the screw shaft 8 can press and fix the blade body 4 indirectly by directly pressing the safety cover 14. Has become.

A metal plate 15 such as a stainless steel plate is provided on the contact surface 1 side of the contact plate 2 to protect the surface from damage. Further, the vertical hole 7 is formed such that the width A at both ends thereof is larger than the width B at the center, and the tip 8A of the screw shaft 8 is disposed at the center.

Next, the operation of the above configuration will be described. The blade body 4 formed by cutting off a part of the continuous blade body 4A through the cutting groove 13 in advance is inserted into the vertical hole 7 together with the safety cover 14, and the screw shaft 8 is tightened to secure the blade body 4 and the safety cover 14 together. When pressed and fixed, the center of the blade body 4 is pressed against the narrow center portion of the width B at one point, and both sides of the blade body 4 are positioned on both sides of the wide width A, thereby fixing the blade body 4 without shaking. it can. At this time, the lower blade edge 13A of the blade body 4 projects slightly below the safety cover 14.

In order to form a scored line (cutting groove) in the workpiece W with a blade flaw, a predetermined dimension is set in advance by the distance between the contact surface 1 and the blade body 4 and the screw shaft is formed. Tighten 10 to fix both. Next, the contact surface 1 is brought into contact with the workpiece W, and the contact surface 1 is slid, whereby a score line (cutting groove) L can be formed by the blade edge 13A. At this time, the starting end 13B, which is the side that comes into contact with the workpiece W at the beginning of the blade edge 13A of the blade body 4, is separated from the end side 13C, which is the side away from the workpiece W at the end of the blade edge 13A. Since the blade body 4 is provided so as to be slightly inclined from the contact surface 1 so as to be separated from the contact surface 1, the blade body 4 always moves away from the contact surface 1 and is ruled. Since the writing line L is formed, the contact surface 1 can always be used in close contact with the workpiece W.

When the blade body 4 is damaged after use in this manner, first, the screw shaft 8 is loosened, the blade body 4 is taken out and discarded, and a new blade body 4, that is, a part of the continuous blade body 4A is further removed. After attaching the blade body 4 formed separately, the screw shaft 8 is tightened and a new blade body 4 is mounted. If the blade body 4 is sequentially damaged in this way, a new blade body 4 is replaced and used.

After use, the blade body 4 is hidden by the safety cover 14 for safety. In this case, once the screw shaft 8 is loosened and the safety cover 14 or the blade body 4 is moved in the vertical hole 7 so that the blade edge 13A is hidden by the safety cover 14, then the screw shaft 8 is tightened and fixed again.

As described above, according to the first embodiment, the contact plate 2 that slides the contact surface 1 against the workpiece W such as a gypsum board, wood, etc. A sliding rod 3 slidably perpendicular to the contact surface 1 of the contact plate 2 so as to be able to protrude and retract, and a blade body 4 provided to protrude downward at the distal end side of the sliding rod 3; Fixing means 5 for fixing the blade body 4 to the sliding rod 3, wherein the blade body 4 is formed by cutting off a part of a continuous blade body 4 </ b> A formed continuously through a cutting groove 13. If the used blade body 4 is damaged, it can be easily replaced by replacing it with a new blade body 4A of the continuous blade body 4A that has been cut off via the separation groove 13. .

Further, in the embodiment, the blade body 4 is moved so that the starting end 13B of the blade edge 13A is separated from the contact surface 1 from the end 13C side of the blade edge 13A. Since the workpiece is slightly inclined from the parallel to the contact surface 1, the workpiece can be in close contact with the contact surface 1 to be ruled. In addition, since the contact surface 1 is formed of a metal plate, even if the contact surface 1 of the metal plate is brought into contact with the workpiece W and slid, the contact surface 1 serving as a reference surface is hard. Therefore, it is hard to be damaged, and it is possible to measure the dimensions accurately for a long period of time, and to draw it.

Further, in the above embodiment, the separating groove 13 is formed obliquely on a blade edge 13A formed on a longitudinal edge of the continuous blade body 4A. Since the intersection of the blade edge 13A and the blade edge 13A is sharply formed, the blade edge 13A of the blade body 4 separated from the continuous blade body 4A is also formed obliquely and sharply formed. W can be favorably ruled.

Further, in the embodiment, a safety cover 14 that slides along the blade body 4 is provided according to claim 4, and the blade body 4 is hidden by the safety cover 14 when not in use. This prevents injuries when not in use.

Moreover, in the above embodiment, a vertical hole 7 is formed at the tip end of the sliding rod 3 according to claim 5, and the blade body 4 and the safety cover 14 are inserted into the vertical hole 7, Further, the vertical hole 7 is formed such that the width A at both ends thereof is larger than the width B at the central portion, and the tip 8A of the screw shaft 8 constituting the fixing means 5 is provided at the central portion of the vertical hole 7, By fixing the central portion of each of the safety cover 4 and the safety cover 14 at one point between the central portion of the vertical hole 7 and the front end 8A, the fixing can be surely performed.

It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention.
