Description

  The present invention relates to a ruler, and in particular, a pair of incisions parallel to a single material plate is made, and an arch portion bulging upward by heating or chemical treatment is integrally formed, and the arch portion is formed. The present invention relates to improvement of a ruler having a structure in which a material plate is closely fixed to an object surface by pressing from above.

  The ruler having the above configuration has already been filed by the applicant of the present application, has obtained a patent right as Japanese Patent No. 5137328, and is further applying for an improved invention.

  However, this conventional ruler slips more effectively as the overall length increases, and the tight fixing force due to pressing is effectively transmitted to the place where the ruler is used, i.e., the edge below the side edge in the length direction. It was also difficult because the stop was only applied to the lower surface of the arch. If the close fixing force due to this pressure is not sufficiently transmitted to the edge, especially when cutting the object with a cutter, it may cause blurring or bending, and when the object becomes cloth, plastic film, leather, The object may be twisted.

  Further, in the conventional ruler structure, when the cutter is used, the cutter may come off from the guide and injure the hand.

  The problem to be solved by the present invention is that a ruler that integrally forms an arch portion on a conventional material plate and presses the arch portion from above to fix it closely to an object is particularly long. The pressing force is not sufficiently transmitted to the edge over the entire length of the ruler fixing, causing blurring and misalignment during the work, and the writing line and cutting line used along the ruler bend. Sometimes the object is twisted, and cutting cannot be performed precisely on a single line.

  In addition, when a cutter is used with a conventional ruler, there are insufficient measures for preventing accidents caused by slipping of the cutter or disengagement from the guide.

In order to solve the above-described problems, the ruler according to the present invention includes a pair of cuts parallel to a single material plate, and both ends of the pair of parallel cuts are larger than the width of the pair of parallel cuts. Narrow the width to form a fulcrum part, then form a small piece part following the fulcrum part, and make a notch refracted in a substantially U shape to surround the fulcrum part and the small piece part to form a strain relief piece In addition, the part sandwiched between the pair of parallel cuts is formed by heating or chemical processing means, and the arch part bulging upward is formed integrally with the material plate. Anti-slip is applied to the entire back surface or partially , and the bottom surface is flat on both edges of the material plate in the direction along the pair of parallel cuts, and the arch portion is pressed with a fingertip from above. Pressing force In a ruler in which a support edge for cutting is formed through a step at a predetermined angle with the bottom surface of the material plate, the arch portion is pressed with a fingertip along the outer edge of each of the parallel pair of cuts. In this case, a pair of parallel ridges for receiving a pressing force from the fingertip and transmitting the pressing force to the support edge is formed .

Further, the ruler according to the present invention is formed on the upper surface on one side along the notch of the material plate by forming an arc-concave groove along the longitudinal direction on the surface on the arch portion side, It is characterized in that a parallel standing wall is provided, and a gap opened downward in cross section is formed below the above-mentioned ridge, and among the above-mentioned pair of ridges, It is characterized in that the side surface is a concave arc surface, and a groove (14) is formed at the boundary between the ridge and the standing wall, and the support edge is formed of a material different from the material plate and attached. It is characterized by being.

Furthermore, the ruler according to the present invention is provided with a stainless steel cutter guide at the side edge on the vertical wall side along the parallel cuts of the material plate, and a guide groove for drawing is provided between the cutter guide and the vertical wall. It is characterized in that it is formed, and the side of the material plate that does not have the standing wall has a trapezoidal shape whose cross section gradually becomes thinner toward the tip.

  The ruler according to the present invention is configured as described above. By providing parallel ridges that receive the pressing force of the fingertips along the outer edges of a pair of parallel cuts, and support edges for receiving the pressing force on both edges along the cuts on the lower surface of the material plate, In addition to the force that presses the arch from above, a pressing force is applied to the ridge, which is transmitted from the ridge to the support edge via the material plate, increasing the tight fixing force to the target surface of the ruler, and strengthening the edge part To fix. Since the action of this force acts in the direction of lifting the support edge outward, the biting force becomes stronger.

  In addition, a standing wall is provided on one side along the notch of the material plate, and an arc-concave groove is formed on the arch portion side of the standing wall, so that a part of the finger pressing the arch portion from above is the standing wall. In particular, a part of the finger is in close contact with the concave groove, and this standing wall is pressed outward, so that the pressing force is applied to the entire length of the material plate, particularly the edge on the side with the cutter guide. In addition, the tighter fixing force of the ruler becomes even stronger.

  In addition, since the standing wall has a concave groove, it also serves as a knob when lifting the ruler, loosens the pressing force on the arch, and puts the fingertip in the pocket formed between the standing wall and the adjacent ridge The ruler can be easily slid in the left-right or diagonal direction by operating the pocket part, and the standing wall is provided on the side where the cutter guide is provided. It is also possible to prevent damage accidents when using.

  This was realized by configuring as illustrated in the drawings and described in the examples.

  Next, preferred embodiments of the present invention will be described. In the figure, reference numeral 1 denotes a ruler body embodying the present invention. The ruler body 1 is formed by processing a single material plate 2 made of a material having a necessary weight and rigidity, such as metal such as aluminum, hard plastic, wood, bamboo and the like. In this embodiment, aluminum is used, and the overall shape is rectangular.

  A pair of parallel cuts are made in the material plate 2 along the longitudinal direction, and both ends along the longitudinal direction of the pair of cuts 3 and 3 are narrowed to be narrower than the width of the cuts 3 and 3. The fulcrum parts 4 and 4 are formed. Subsequent to this fulcrum part 4, 4, a small piece part 5, 5 is formed, and a substantially U-shaped refracted notch 6, 6 is inserted so as to surround the fulcrum part 4, 4 and the small piece part 5, 5. The part surrounded by 6 and 6 is used as a strain relief piece. And the part pinched | interposed into a pair of parallel cut | notch 3 and 3 is made into the arch part 7 bulging upwards by heating and a chemical process. Further, the back surface of the arch portion 7 is provided with a non-slip 8 made of rubber or the like that comes into contact with the object when the arch portion 7 is pressed from above.

  On the surface side of the ruler body 1, parallel ridges 9 and 9 a are integrally formed along the outer edges of the pair of parallel cuts 3 and 3. The protrusions 9 and 9a can press the arch portion 7 with a fingertip and receive a pressing force from the fingertip when the arch portion 7 is in close contact with the object, and can be transmitted below the full length side edge of the ruler body 1.

  Further, on the lower surface side of the ruler body 1, support edges 10 and 10 a for receiving a pressing force by a fingertip are integrally formed on both edges (both edges along the longitudinal direction) along the pair of parallel cuts 3 and 3. It is molded into. That is, when the ruler body 1 presses the arch portion 7 and comes into close contact with the object, not only the back surface of the arch portion 7 but also the support edges 10 and 10a exerts a dense pressure. The angle formed inside the support edges 10 and 10a acts in the direction of warping due to the pressing force from above, thereby increasing the dense pressure.

  A stainless steel cutter guide 11 is integrally provided on the outer surface of the ruler body 1 along the above-described protrusion 9. The reason why the cutter guide 11 is made of stainless steel is to prevent the ruler body 1 from being damaged by the blade of the cutter.

  Further, a standing wall 12 is integrally provided in parallel with the ridge 9 between the side surface provided with the cutter guide 11 and the one ridge 9, and a cross section is provided on the inner surface side of the standing wall 12. A groove 12a having an arc concave shape is formed. A guide groove 13 for drawing is provided on the surface between the standing wall 12 and the side surface on which the cutter guide 11 is provided.

  Further, the side surface of the one ridge 9 on the side of the standing wall 12 is formed as a concave arc surface 9b, and a groove portion 14 is formed in a boundary portion with the standing wall 12, thereby forming a pocket portion into which a fingertip fits. In the figure, reference numeral 15 denotes a through-hole for hanging the ruler main body 1.

  The ruler body 1 according to the present embodiment is configured as described above. The form of the ruler body 1 can be modified as shown in FIGS. In the case of FIG. 13, the support edges 10 and 10 a are molded and attached using a material different from the material plate 2. In this case, if the material is stainless steel, it can be mounted as a right angle bar integral with the cutter guide 11.

  In the example shown in FIG. 14, gaps 16 and 16 a are formed below each protrusion 9 and 9 a so that one layer of elasticity can be given, and the protrusion 9 and 9 a is pressed. The pressing force is transmitted to the support edges 10 and 10a by the elastic force generated by the gaps 16 and 16a. In addition, the cutter guide 11 is attached by forming a dovetail groove 17 on the side surface of the material plate 2 and slidingly attaching a guide on the back surface of the cutter guide 11 to the dovetail groove 17.

  Further, the example shown in FIG. 15 is obtained by further changing the structure of the gaps 16 and 16a shown in FIG. 14 and has a U-shape with the gaps 16 and 16a opened downward in the cross section. The shapes of the strips 9 and 9a are also U-shaped in cross section, and the pressing force transmitted to the inner corners of the support edges 10 and 10a is increased.

  Further, the example shown in FIG. 16 is a further modification of the example shown in FIG. 15, in which the presence of the concave arc surface 9 b of the ridge 9 is eliminated, and the groove 14 is deepened accordingly. Since the groove 14 is deepened, the presence of the groove 12a of the standing wall 12 is unnecessary. The cutter guide 11 is attached via a dovetail groove 17 as in the example shown in FIG.

  When the ruler body 1 configured in this manner is pressed against the arch portion 7 with a fingertip from above, the anti-slip 8 on the back surface of the arch portion 7 is in close pressure contact with the object, and at the same time, the protrusions 9 and 9a are pressed. At the same time, the standing wall 12 is pushed from the inside, and the pressing force is transmitted to the support edge 10, 10a through the material plate 2, and the edge of the ruler body 1 is floated when using the cutter or drawing with a writing instrument, It is possible to carry out elaborate and accurate work without shifting. The higher the height of the standing wall 12, the greater the transmission force. Further, the standing wall 12 is useful as a knob or when the ruler body 1 is slid to the left and right and obliquely.

  The present embodiment is configured as described above. In this embodiment, the ruler body 1 is assumed to be long, so that when the ruler body is short, the presence of the standing wall 12 is not necessary for transmitting the pressing force to the support edge. In addition, the presence of the protrusions 9 and 9a can be formed on the lower side of the cuts 3 and 3, that is, on the back surface of the ruler body. In addition, the ruler body 1 is not limited to a straight one, and can be applied to a curved one.
