  When performing scribing with a ruler or cutting with a cutter knife, the pressed part becomes the point of action, making it easier to rotate and resisting the force applied by a writing instrument or cutter knife applied to the ruler. It was considered to be effective for preventing the ruler from shifting without breaking and preventing the fingertip from being damaged by the cutting edge. However, riding accidents caused by cutting edges such as cutter knives on a ruler have not been resolved and remain as problems.

  In this remaining problem, for example, when cutting a piece of paper as a non-cutting object in a cutting operation, apply a ruler to the ruler and apply it to the blade edge guide part of this ruler. A method has been adopted in which the cutting edge is slid in contact with the cutting edge, the cutting edge is brought into contact with paper, and the cutter knife is moved while being tilted at an acute angle in the traveling direction. For this reason, when performing the cutting work, be careful not to make a mistake so that the hands with the cutter knife work too hard and the slight hand shake of the hand holding the cutter knife occurs. Therefore, the cutting edge moving while falling at an acute angle bites into the upper end portion of the cutting edge guide as it is at an acute angle, and runs over the ruler with excessive force. Often in the above situation, the accident leading to the ruler by the tip was caused.

Next, when it is necessary to more accurately measure and confirm the scoring position in the ruled line drawing and scoring work with a conventional ruler with a scale, in order to reduce visual errors due to the effect of light refraction, use a ruler. Check the measurement while raising the ruler with both hands around the corner of the scale at the side end along the longitudinal direction of, and hold the ruler with your hands so that it does not shake, and draw a ruled line with a writing tool etc. I was working, but the work was very nervous and not easy.

  Conventionally, a ruled line cutting and ruled cutting work while moving parallel to a three-dimensional workpiece, or a three-dimensional extended ruled line drawing and ruled line cutting by shifting to an adjacent surface such as a square or a flat plate, etc. There was no ruler that allowed work alone.

In addition, there is no ruler that can easily perform ruled line drawing and ruled line cutting on a brushed material or a sponge sheet.

  In view of the above-mentioned conventional drawbacks, the present invention can prevent deviation of a ruler in ruled line drawing and scoring work, and can perform ruled line work and creased work while moving in parallel, and to the adjacent surface of square material. The transition extension ruled line drawing and the transition extension ruled work can be performed, the ruled line cutting and the ruled line cutting work can be easily performed on a brushed material, a sponge sheet, and the like, and the measurement position can be easily visually checked. In addition, a shield wall with a simple structure has been provided that eliminates the accident of climbing onto the ruler due to the cutting edge of the cutter knife that occurs during the cutting work of paper and workpieces, and enables light, safe and efficient work. It aims to provide a variety of rulers.

  In order to achieve the above object, according to the present invention, a shield wall is integrally provided at one side edge along the longitudinal direction of the ruler main body, and both the bending prevention, the guide surface, and the protection surface are provided via the shield wall. It constitutes a variety of rulers with shields in the structure.

  According to the present invention, the following effects can be obtained.

(1) Since a shield wall is integrally provided at one side edge along the longitudinal direction of the ruler body to prevent deflection and to have both a guide surface and a protection surface via the shield wall, paper When a force is applied to a point at the center of the upper surface of the ruler across the ruler or the workpiece, the force is transmitted to the entire ruler and the paper and the workpiece can be suppressed evenly, thereby solving the problem of the rotation of the ruler. Can do things. Therefore, rotation of the ruler can be eliminated, and failure due to deviation of the ruled line drawing operation and the score cutting operation caused by the rotation can be eliminated, and the operation efficiency can be improved.

(2) According to the above (1), even if the hand for pulling a knife such as a cutter knife in operation is slightly blurred, a shield wall is provided integrally on one side edge, and the shield wall is bent. Since it has both the prevention, the blade guide surface and the fingertip protection surface, the turning phenomenon of the ruler can be greatly improved, and the accident of climbing on the ruler due to the cutting edge of the blade such as a cutter knife can be prevented. Can be prevented. Therefore, it is possible to eliminate the damage to the ruler due to the cutting edge of the blade such as a cutter knife, and it is also possible to eliminate the injury to the fingertip due to the cutting edge of the blade during the cutting operation, so that the cutting operation can be performed with confidence. .

(3) Due to the above (1), even if the hand that presses the ruler is excessively stressed, the force is evenly transmitted to the entire ruler and acts on the ruler more stably. Therefore, even a person who is unfamiliar with the work does not need to worry about the displacement due to the rotation of the ruler, it is possible to draw a beautiful ruled line, and the cutting and cutting work can be done safely, quickly and with a beautiful finished work.

(4) By the above (1), a three-dimensional outgoing and incoming angle of a square member, a workpiece or the like can be slid and moved through two surfaces of the ruler body and the shield wall. Therefore, parallel ruled line drawing and parallel scoring work using the end side of the ruler, and three-dimensional extended ruled line drawing and scoring operation by transitioning to an adjacent surface such as a square or flat material can be easily performed.

(5) According to the above (1), since the ruler has a shape that can be easily gripped, the ruler can be smoothly moved on the paper surface or the workpiece surface, which is convenient. Therefore, work can be performed efficiently.

(6) According to (1), since the structure is simple, it can be implemented easily at low cost. In addition, it is light and convenient to carry.

(7) According to the above (1), it is easy to use and anyone can use it safely and conveniently.

(7) A shield wall is integrally provided at one side edge along the longitudinal direction of the ruler main body, and the ruler body is configured to have both a bending prevention, a guide surface, and a protection surface via the shield wall. When the ruler is used face down, i.e., in opposition to normal use, it is possible to replace the pressing with a flat surface with a pressing with a partially acting line. Therefore, it is possible to easily perform ruled line drawing, scoring work, and cutting / cutting work on a material such as a raised material or a sponge.

(8) The first example of the specific embodiment also provides the same effects as the above (1) to (8) and uses a ruler with a transparent synthetic resin scale attached to the bottom surface of the ruler body. The ruler guide surface of the ruler can be used as a bottom surface, and the scaled surface can be held up on a shield, so that it can stand on paper or a work surface. Can be. Therefore, it is possible to visually check the scale while performing another operation, thereby improving the operation efficiency.

(9) In the second example of the specific embodiment, the same effects as those of (1) to (8) can be obtained, and the bottom surface of the other edge of the ruler with respect to the shield wall is not cut. In addition, it is possible to easily provide a gap. Therefore, the dragging phenomenon of the wet ink immediately after printing by the ruler can be eliminated, and the operation can be performed without worrying about contamination of the screen.
The effects of the invention enumerated above can be obtained.

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.

  In the best mode for carrying out the present invention shown in FIGS. 1 and 3, reference numeral 1 denotes a ruler body. The ruler body 1 is an elongated straight ruler. Reference numeral 2 denotes a shield wall. The height of the shield wall 2 is a size sufficient to prevent the bending of the ruler body 1 and protect the fingertips, and is substantially perpendicular to the edge 1d along the longitudinal direction of the ruler body 1. The end face is formed in an L-shape by being integrally provided so as to be bent. 1a is the upper surface of the ruler body 1. 1b is a bottom surface of the ruler body 1. Reference numeral 1c denotes an inclined portion provided on the other ruler edge 1f opposite to the shield wall 2, but the presence or absence of the inclined portion 1c is not limited. 1d is a ruler edge. The ruler edge 1 d is an edge that integrates the ruler body 1 and the shield wall 2. 1e is a main body end face of the ruler main body 1, and the main body end face 1e is described by attaching the same symbols to both end faces. Reference numeral 2a denotes a fingertip protection surface shared by the shield wall 2. Reference numeral 2b denotes a blade edge guide surface of a blade such as a cutter knife which is also provided for the shield wall 2. 2e is the shield wall end face of the shield wall 2. The end face 2e of the shield wall is described with the same reference numerals on both end faces. 2f is a shield wall edge.

  For the production of a multi-purpose ruler provided with a shield wall configured as described above, a member manufactured by continuous extrusion molding of an aluminum material into a so-called L-shape in a sectional shape shown in FIG. It has been obtained.

  In the best mode for carrying out the present invention, the ruler body 1 and the shield wall 2 are made of light metal aluminum, but if the material is sufficient to guide the cutting edge and protect the fingertip. There is no particular concern.

  The description of the use of the multi-ruler provided with the shield wall of the present invention having the above-described configuration will be described with reference to FIG. Reference numeral 7 denotes a cutter knife, and 7b denotes the side of the blade edge of the replacement blade portion of the cutter knife. The display of the side of the blade edge 7b is described using the same reference numeral 7b on the side in contact with the blade side guide surface 2b in the figure. . Reference numeral 7a denotes a cutting edge of the replacement blade of the cutter knife 7. Reference numeral 7c denotes a cutting edge of the cutter knife 7. Now, for example, when cutting the paper 8, the cutting position of the paper 8 to be cut is determined, and the lower edge of the blade guide surface 2 b of the ruler is set in accordance with the cutting position of the paper 8, and the upper surface 1 a of the ruler body 1 is cut. With one finger, the cutting edge 7a of the other cutter knife 7 held in the hand is pushed up to the paper 8 while the cutting edge 7a is directed to the cutting edge guide surface 2b, and the cutting edge is tilted in the traveling direction. The side 7b is moved so as to slide on the blade guide surface 2b. At this time, the cutting edge 7a smoothly cuts the paper 8 along the cutting edge guide surface 2b indicated by the various rulers provided with the shield wall of the present invention.

  The operation during the work is described below. The ruler provided with the shield wall of the present invention has a structure in which the shield wall 2 is integrally provided substantially at right angles along the edge 1d along the longitudinal direction of the ruler body 1. As a matter of course, the shield wall 2 acts as a vertical rib of the ruler body 1. Therefore, the bending caused by the force applied to the upper surface 1 a of the ruler body 1 is prevented via the shield wall 2. For example, the force of one fingertip applied to the central portion of the upper surface portion 1a of the ruler is transmitted to the side wall 2, the force is dispersed and transmitted to the entire ruler body 1, and the force acts on the entire bottom surface portion 1b. become. Therefore, the concern that the pressed portion becomes the point of action and the rotation is eliminated is eliminated, and the paper or the workpiece can be pressed almost evenly.

  The one-handed fingertip holding down the upper surface portion 1a is protected by the shield wall 2, which is configured to be higher, having a structure combining the cutting edge guide surface 2b and the fingertip protection surface 2a. Even if the hand holding the cutter knife 7 slightly fluctuates due to the shield wall 2 having the blade edge guide surface 2b which is set higher, even if the hand holding the cutter knife 7 slightly shifts, the edge guide edge 2f of the blade edge guide surface 2b extends to the edge 2f of the upper shield wall. It is possible to prevent a run-in biting accident caused by the cutting edge 7c. Accordingly, a fingertip damage accident caused by the cutting edge 7a beyond the shield wall 2 cannot occur. Incidentally, during the operation, the one-handed fingertip holding down the upper surface 1a is always protected by the fingertip protection surface 2a integrally provided on the front and back sides with the shield wall 2.

  Next, when performing ruled line drawing or scoring work with a writing instrument, the inclined portion 1c provided on the other edge of the ruler body 1 with respect to the shield wall 2 side is placed in front, and the upper part of the shield wall 2 is placed with a fingertip. This allows the user to move to the plane while holding it, and to smoothly perform ruled line drawing and scoring work at the measurement point position.

  Then, for example, a description will be given of a ruled line drawing and a scribing operation on a three-dimensional surface adjacent to a corner of a bar 9 as a workpiece with reference to FIG. 9 is a square lumber. The square lumber 9 is a general lumber. 10 is a writing instrument. The writing implement 10 is a pencil. Reference numeral 11 denotes a ruled line or a mark after a ruled book. Now, two surfaces having an angle formed by the upper surface portion 1a and the fingertip protection surface 2a of the ruler body 1 and the shield wall 2 and the bottom surface portion 1b and the cutting edge guide surface 2b are addressed to the corners of the bar 9 The ruler is moved to an arbitrary position, and a work of writing a ruled line or a mark of a ruled mark is performed while the writing implement 10 is along the sides of the end side 1e and the end side 2e. In addition, a three-dimensional extended ruled line can be drawn to an adjacent surface such as a rectangular timber or a flat plate, or a transition of a scribing operation can be similarly performed.

  Next, the operation of drawing a ruled line on a raised material or a sponge sheet or cutting a ruled line will be described with reference to FIGS. 15 and 16 using a sponge sheet as an example. 12 is a sponge sheet. The sponge sheet 12 is generally made of a commercially available elastic urethane foam product, but the operation and effect are not changed even if other materials are used. Now, when the various ruler provided with the shield wall is provided at a predetermined position of the sponge sheet 12 with the bottom surface 1b and the blade guide surface 2b facing upward in the various ruler provided with the shield wall of the present invention, The sponge sheet 12 is held down by two lines of the edge 2f and the straight edge 1f. Naturally, the applied force is intensively applied to these two lines, and the resilient and elusive sponge sheet 12 is secured with the two lines of the shield wall edge 2f and the straight edge 1f. It is possible to determine the cutting position of the scored line because it can be suppressed.

  Next, a first example of the specific embodiment of the present invention shown in FIGS. 4 and 10 will be described. In describing a first example of a specific embodiment of the present invention, the same components as those in the best mode for carrying out the present invention will be denoted by the same reference numerals, and redundant description will be omitted. .

  In the first example of the specific embodiment of the present invention shown in FIG. 4 to FIG. 6, the main difference from the best mode for carrying out the present invention is that the best mode for carrying out the present invention is different. The point is that a ruler 3 with a transparent scale made of synthetic resin is adhered to the bottom surface 1b of the ruler body 1 in a multi-ruler provided with a shield wall. Reference numeral 3 denotes a scale ruler made of synthetic resin. 3a is a resin upper surface part. 3b is a resin bottom portion. The size of the ruler 3 with scale is the same as the length of the ruler body 1, and the width is large enough to see through the characters and ruled lines under the parts that do not overlap after pasting. The scale 4 is applied to both edges of the resin bottom surface 3b, and a square cut 3c is provided on the upper surface of the scale 4 at one edge. In addition, the scaled ruler 3 and the ruler main body 1 are cut down from the resin upper surface 3a by the thickness and width of the ruler 1 so that the upper surface of the ruler body 1 is flush with the upper surface of the ruler 1 after the sticking, thereby forming a sticking surface 3s. It has a structure. The sticking method is based on an existing technique, for example, a synthetic adhesive, and is not particularly limited. Reference numeral 3d denotes a resin edge surface in the ruler 3 with a scale. The resin edge surface 3d is on the same plane as the cutting edge guide surface 2b. 3e is a resin end face in the ruler 3 with a scale. The resin end face 3e is on the same plane as the main body end face 1e and the shield wall end face 2e. Reference numeral 3f denotes another resin edge end surface with respect to the resin edge end surface 3d, which is a side provided with the square cut 3c.

  In the above embodiment, the resin upper surface 3a of the ruler 3 made of synthetic resin is cut down by the thickness and width of the elongated plate-shaped ruler main body 1, but the cut-down is performed. Even if it is carried out without performing, the operation and effect do not change.

  Next, a description will be given of the use of the first example of the specific embodiment of the above configuration. The same components as those in the best mode for carrying out the present invention will not be described. Normally, the measurement of the scored position and the ruled line drawing with the writing tool can be performed using the other resin edge 3f as a guide. Now, the characteristic usage of the first example of the concrete embodiment will be described with reference to FIG. When the cutting edge guide surface 2b of the shield wall 2 is set as the bottom surface, the transparent ruler 3 made of synthetic resin is raised, that is, the resin bottom portion 3b is made to stand on the measurement surface 6 independently. Then, the measurement surface 6 is partitioned with the lower edge of the resin bottom portion 3b standing upright as a boundary line, and the measurement surface 6 on the opposite side is left behind the partitioned measurement surface 6 while the aluminum measurement shield is left. Shielded by wall 2. Therefore, the printing portion provided at the side end of the scale 4 provided on the scale ruler 3 made of a transparent synthetic resin acts so as to directly catch the point 6a to be measured on the measurement surface 6 at a so-called pinpoint. Therefore, it is difficult to see due to the overlap of the other lines written on the measuring surface 6 with the printed lines of the scale 4, and it is easy to visually check without being affected by the refractive index of the transparent synthetic resin product. Since the resin bottom portion 3b and the upper surface portion 1a can be pressed while being held, the ruler can be securely fixed and the scoring work can be easily performed. When performing ruled line drawing and ruled line cutting work, efficient work can be performed while visually checking the ruled line, the ruled position, and the cutting position under the ruler 3 with the scale.

  As described above, the present invention can be applied to a multi-purpose ruler provided with a shield wall having a configuration in which a transparent synthetic resin scale ruler 3 is attached to the bottom surface of the ruler body 1. The same operation and effect as those of the best mode of the present invention can be obtained, and the above-mentioned operation and effect which have not been provided in the past can be obtained.

  Next, a second example of the specific embodiment will be described with reference to FIGS. 11 and 13. The difference from the first example of the specific embodiment of the present invention is that the upper surface 1a of the ruler body 1 is transparent. The point is that the resin bottom portion 3b of the graduated ruler 3 made of synthetic resin is attached and used. In describing a second example of the specific embodiment of the present invention, the same components as those of the best mode for carrying out the present invention and the first example of the specific embodiment are denoted by the same reference numerals. And duplicate descriptions are omitted.

  The transparent ruler 3 with a scale in the second example of this specific embodiment is larger than the width of the scale on the upper surface 1a of the ruler body 1 provided with the shield wall. It has been set. Reference numeral 3f designates 3d of the ruler 3 made of synthetic resin. The resin edge 3d is brought into contact with the fingertip protection surface of the ruler body 1 provided with the shield wall, and the resin bottom surface 3b is overlapped with the upper surface 1a. When pasted, the portion that does not overlap in the above-described state forms a space D with a margin, so that characters, lines, and the like below can be confirmed through the portion. As described above, even if the hand D is slightly shaken due to the space D having a margin, there is no fear of causing drag stain by wet ink immediately after printing with the resin edge 3f as a guide. I can work with my heart.
