Description

  The present invention relates to a ruler used for writing a line or cutting with a cutter, and in particular, it can be brought into close contact with the surface of an object such as paper or cloth. It is related with the improvement of the ruler which aimed at not producing.

  Traditionally, the ruler is generally used to draw straight lines, as well as a triangle ruler, a circle ruler, an ellipse ruler, a cloud ruler, a T ruler, a parallel ruler on a drafting table, and a letter. There are various things such as templates for drawing and symbols.

  This conventional ruler is usually formed of a flat plate such as plastic, wood, bamboo, metal, etc., and is supposed to be in plane contact with the surface of the object to be drawn. When a line is drawn using this ruler, the ruler is pressed from above with the fingertip of one hand, the writing instrument is held with the other hand, and the tip of the writing instrument is moved along the edge of the ruler.

  Here, the fingertip that presses the ruler is difficult to extend over the entire ruler, and since it becomes a point, this presser part becomes a fulcrum, and pressing with a writing instrument at a part away from this fulcrum becomes an action point, There is also a situation where the ruler is rotated, and in order to prevent this, increasing the pressing force makes the work feel tired.

Therefore, the inventor arranges an arch member having a spring property on the surface of the ruler, and interlocks with the pressing of the arch member to project the anti-slip member downward, thereby smoothly positioning the ruler and moving the position of the ruler. Proposed a ruler that could be done.

In these drawings, reference numeral 1 denotes a ruler body. The ruler body 1 is mainly formed of a rectangular material plate made of plastic, but this material can be formed of metal, bamboo, wood, paper, etc. in addition to plastic. Of course, the ruler body 1 can also be used as a ruler by placing a scale on the side edge along the longitudinal direction.

  The ruler body 1 is integrally formed with an arch portion 2 having a central portion bulging upward in a substantially central interior along the longitudinal direction. This arch portion 2 is formed with a pair of parallel cuts 3 and 3 along the longitudinal direction of the material plate, and the part sandwiched between the parallel cuts 3 and 3 is heated, rubbed, injection molded, chemically treated, etc. It is formed by being deformed by the processing means.

  Further, the notches 3 and 3 are narrowed at both ends to form fulcrum portions 4 and 4, and the tip portions of the fulcrum portions 4 and 4 are small pieces 3a and 3a. That is, in this embodiment, the portion sandwiched between the chain lines in FIG. 1 is the portion where the arch is actually formed. Further, a substantially U-shaped cut 5 is formed so as to surround the fulcrum portions 4 and 4 and the subsequent small pieces 3a and 3a, and the strain relief pieces 6 and 6 are formed by the cut 5.

  Further, a slip stopper 7 is provided on the back surface of the arch portion 2 described above. The anti-slip 7 can be implemented by a means for printing a coating material that is soft and non-slip, in addition to sticking a sheet having a large friction coefficient such as a rubber sheet with an adhesive or a double-sided tape. In this case, it is possible to draw a character, a pattern, or the like with this paint to make it a novelty, and the character or the pattern can be expressed by engraving on a rubber sheet.

  The ruler main body 1 according to the present embodiment is configured as described above. When the ruler main body 1 is placed on a target paper surface and the like when used, and the arch portion 2 is pressed, the arch portion 2 is cut 3. 3, the anti-slip 7 comes into contact with the paper surface and the like and is positioned. At this time, the excess volume due to the arch portion 2 entering the opening is transmitted as stress to the strain relief pieces 6 and 6, and the strain relief pieces 6 and 6 are lifted upward as shown in FIG. The working part of the ruler main body 1 is not affected at all.

  If the material plate is molded of plastic and it is long, the thickness will be thin. Therefore, the thickness is about 5 mm, and the back surface from the arch part 2 and the fulcrum part 4 to the strain relief piece 6 is formed. The spring property of the arch part 2 can be adjusted to a thickness of about 3 mm by cutting 8. In the case of this long object, the arch part 2 can be formed intermittently continuously in the longitudinal direction, and the distortion relief piece 6a at the extreme end of the ruler body 1 is not U-shaped but is formed as a parallel cut 5a. The cut may be formed up to the end of the ruler body 1. In addition, even if it is a thick material plate and is long, if it is wide and the arch part is long, it is not necessary to add a special cutting process.

In the case of FIGS. 12 and 13, the ends of the work rods 11 and 11 extending in a bow shape from the handle 9 are fixed between the top surfaces of the two arch portions 2 and 2 described above. As the relief, the strain relief pieces 6 and 6 continuously lifted on the arch portions 2 and 2 act.

  FIG. 14 to FIG. 16 are examples of the cut for strain relief described above, and FIG. 14A is as described above. In the case of FIG. 14B, the notches 3 and 3 are extended and the tip thereof is turned inward by 180 degrees, and the core is formed in a direction opposite to A so as to surround the narrow small piece 3a formed there. A character-shaped notch 5b is inserted and the strain relief piece 6 is formed between the parallel small pieces, and the force applied to the arch portion 2 acts in the lateral direction.

  The case of FIG. 15 is an example of distortion relief in which the force applied by the shape and combination of arch portions described later becomes horizontal and vertical. A narrows the notches 3 and 3 to form a small piece portion 3a. The notches 3 and 3 are formed by bending the tips of the notches 3 and 3 outwardly and partially opening the periphery of the small piece portion 3a. A square notch 5c is inserted to form a strain relief piece 6. B has a configuration corresponding to B in FIG. 14, and a notch 5 c in FIG. 15A is made in the reverse direction, and a strain relief piece 6 is formed inside the arch portion 2. In the case of C, both ends of the incisions 3 and 3 are bent inward at substantially right angles, and a T-shaped portion having a hem extending outwardly in the end portion of the arch portion 2 is formed by an incision 5d between them. 6.

  In addition, the case of FIG. 16 is an example of strain relief in which the applied force is horizontal, vertical, and horizontal. In the case of A, the tips of the notches 3 and 3 are narrowed to form a narrow small piece portion 3a, and the tip is bent so as to go outward. And the circumference | surroundings of the bending part are made into substantially U shape, and the notch 5e bent so that the front-end | tip turns around inside may be put, and the strain relief piece 6 may be formed. In the case of B, the notch 5e described above is put in the end of the arch part 2 in the opposite direction, and the notches 5f and 5f whose ends are turned outwardly toward the inside are symmetrically put, and the strain relief piece 6 Is forming. In the case of C, the tips of the notches 3 and 3 are narrowed to form a small piece portion 3a, and the tip is bent outward at a substantially right angle. Then, a notch 5g having a substantially inverted C-shape is doubled in a single-stroke shape around the periphery, and the notch 5g is discontinuous at the inner central portion, thereby forming a strain relief piece 6.

  Further, FIG. 17 shows ruler bodies 1, 1... In which the above-described strain relief structure is applied, and in particular, the type of FIG. In the case of A, it is the same type as that shown in FIGS. 1 to 5 described above, but in the case of B, the arch portion 2 is formed along the short direction of the ruler body 1, that is, in the vertical direction. In the case of C, those shown in A and B are combined, and the arch portion 2 is formed in a cross shape. Further, the case shown in D is of the type in which the arch portion 2 is configured as the one shown in FIG. In the case of E, the central portion along the longitudinal direction of the material plate is cut to form an integral strip, and the strip is folded back toward the ruler body 1 to form the arch portion 2. This folded portion has a stepped portion 2b at the base end, and also has a stepped portion 2b at the tip, and is welded inward in the vertical direction. That is, when the arch portion 2 is pressed with this configuration, the stepped portion 2b functions as a strain relief portion that escapes upward. In addition, in order to form this arch part 2, the width | variety with the ruler main body 1 may not be sufficient.

  Further, the ruler body 1 shown in FIG. 18 is provided with a pair of slits 12 and 12 having a gap slightly larger than the notches 3 and 3 in parallel, and the part between the slits 12 and 12 is formed in the arch portion 2 by the method described above.

The ruler body 1 shown in FIG. 36 has an arch portion 2 formed by slits 12 and 12, and the slits 12 and 12 are further extended continuously. For example, as shown in FIG. The mountain-shaped through-hole portions 12a, 12a,... Are alternately formed, and the through-hole portions 12a, 12a,. When a pressing force is applied to the arch portion 2 from this configuration, the pressing force contracts the through holes 12a, 12a, etc., and lifts the end portion 2d of the arch portion 2 to release the distortion. FIG. 37 is a modification of the above-described example. In addition to the through-hole 12a continuous to the slit 12, a diamond-type through-hole 12a is separately drilled in the central portion of the end 2d of the arch portion 2. Similarly, the tip 2d portion of the arch portion 2 surrounded by the through holes 12a, 12a,...

It is made small to assist the sliding of the contact surface 1b. On one side, since the bending angle and the width of the notch 21b are narrow, the resistance is increased and the step is stretched against the pressing force. The notches 21a and 21b can be replaced by punching holes 23 or the like.

  The above-described configuration is more effective by gradually reducing the thickness on the side having the contact surface 1b toward the edge thereof, and has the contact surface 1b as shown in FIG.

  65 to 69 show a ruler body 1 of a type in which various straight slits 12 are combined in a material plate to form an arch portion or a spring holding portion. A ruler main body 1 shown in FIG. 65 has a slit 12 parallel to a substantially central portion along the longitudinal direction of a flat material plate, and the end of the slit 12 is continued in a perpendicular direction, and one of the slits 12 is extended. , It is refracted at right angles and opened at the longitudinal edge of the material plate. And the part pinched by the chain line of the part pinched | interposed by the slit 12 is made into the arch part 2 where the center site | part expanded. When this arch portion 2 is pressed, a relief stress is generated in the direction of the arrow in the figure from the form of the slit 12, and the bottom surface of the ruler body 1 is in close contact with the target surface. The back surface of the arch part 2 is provided with a non-slip. In this example, length scales having different units are put on the respective edges formed by the slits 12, bent and held using the wrist or fingertip, and can be used as a ruler in each unit. .

  The ruler body 1 shown in FIG. 66 has a structure in which the slit 12 is further extended and opened at the edge in the short direction as compared with the case of the ruler body 1 of FIG. That is, the slit 12 is a triple, and a pair of arch portions 2 and 2 are formed in parallel with the slit 12 at the center. In this case, a slip stopper is provided on the back surface of each of the arch portions 2 and 2. 67 and 68 are modified versions of FIGS. 65 and 66, respectively.

In this case, a slip stopper is provided on the back surface of each spring piece 29.

  The ruler body 1 shown in FIG. 69 is formed by bending the end of the slit 12 along the longitudinal direction of the material plate at a right angle and making the slit 12 substantially U-shaped, and the portion surrounded by the slit 12 is elongated. In the example shown in A, the slit 12 is further extended and opened at the edge along the longitudinal direction of the material plate. In the case of B, the opening is not opened, and the edge of the material plate opposite to the lifting edge of the spring piece 29 is lifted by the pressing of the spring piece 29, and the force is transmitted to the other edge (edge) by the lifting. ing. In order to make this more effective, a convex portion that prevents the lifting is formed on the outside of the slit 12 that is bent at a right angle, so that all the force required for the lifting is applied to the other edge. I can tell you.

  The ruler body 1 shown in FIGS. 70 to 72 is a type in which the principle of the lever is applied by the pressing force of the arch portion 2 and the bottom surface of the ruler body 1 is brought into close contact with the target surface. The ruler body 1 shown in FIG. 70 is folded at one side to form an arch portion 2, which has a slip stopper 7 on the back surface thereof, and a window hole 16 through which the slip stopper 7 enters and exits. Further, the distal end of the arch portion 2 is bent upward to form an engaging portion 2e, and the engaging portion 2e is folded and welded to engage the inner surface of the receiving portion 30 having an arc shape at the distal end. When the arch portion 2 of the ruler main body 1 is pressed, the anti-slip 7 enters the window hole 16, and the engaging portion 2e applies a force for pushing the receiving portion 30 obliquely upward. In this case, a force to be pressed downward is generated.

  In the case shown in FIG. 71, the arch portion 2 is provided by using another member, and the engaging portions 2e and 2e are integrally formed at both ends thereof. The receiving portions 30, 30 are formed by folding back both sides of the material plate, and the force of the lever principle due to the pressing of the arch portion 2 is transmitted to both ends of the ruler body 1. Further, the ruler main body 1 shown in FIG. 72 is formed of four parts in addition to the arch part 2 as well as the members of the receiving parts 30 and 30, and its action is the same as that of the ruler main body 1 of FIG.

Straight slip stoppers 7c and 7c as described above are provided on the upper side edge of the window hole 16. The slip stoppers 7 c and 7 c may be formed on the back surface of the arch portion 2. When the arch portion 2 is pressed here, the anti-slip 7c, 7c prevents the rattling and the anti-slip 7 enters the window hole 16 and is in close contact with the target surface. However, if the notches 21, 21,. As shown in FIG. 78B, both edges of the arch portion 2 can be bent outward, and the non-slip 7 can be more closely contacted.

  The example described above can be applied not only to the straight ruler but also to various rulers as described above. As an example, FIG. 79 shows an example applied to the isosceles triangle ruler body 1. In this case, the notches 3 and 3 form a three-way arch portion 2 as parallel radial shapes, and distortion relief pieces 6 and 6 are formed by the notches 5 and 5 at each end portion thereof. Further, the ruler main body 1 shown in FIG. 80 is of a right-angled curved type.

In addition, D shows an example in which two anti-skids 7 are stacked, and E shows an example in which convex portions are formed on the top and bottom. F indicates a case where a pressing convex portion is formed on the lower surface of the arch portion 2, and G indicates a case where an additional non-slip 7 is provided in place of the pressing convex portion. Further, H and I indicate the anti-slip 7 disposed on the lower surface side of the window hole 16 of the ruler body 1. When this type is a two-sheet ruler, it can be implemented with or without a gap between the anti-slip sheet 7 and the window hole 16.

  The ruler body 1 shown in FIG. 85 is a modification of the technique described in the patent literature. The arch spring member 2 is covered on the base plate of the ruler body 1 and the rounded operation part 2g at the end thereof is covered with the presser fitting 37. A pressing protrusion 2h is integrally formed on the back surface of the arch spring member 2 with a constant interval. The base plate is provided with a window hole 16, and the window hole 16 is formed with an anti-slip 7 having a convex step portion in the vertical direction, and the convex portion 2 h of the arch spring member 2 is guided on the upper surface of the opening edge of the window hole 16. The rib 1i to be fixed is fixed with a screw or the like, and the rib 1i and the slip stopper 7 are not integrated, and a cut is formed in the middle. Further, the anti-slip 7 can be formed by forming a convex portion only on the lower surface by the part of the ruler body 1, and the anti-slip 7 in this embodiment has a function of floating both ends of the arch spring member from the lower surface in addition to the anti-slip function. It also serves as an anti-catalytic function. Further, when the ruler body 1 is long and the arch spring member 2 is heavy, and it is difficult to support the arch spring member 2 with only the anti-slip tensions at both ends, the reinforcing leaf spring 52 is prevented from slipping as shown in the figure. 7 may be sandwiched between the upper surface positions. In this case, the reinforcing plate spring 52 is held in a bending or descending motion by, for example, making a continuous crank-like cut.

  As shown in FIG. 86, when the gate part 38 for preventing lateral rubbing is interposed between the two arch parts 2, 2 or one arch part 2, the side edge of the arch part 2 is pushed down to the slip stopper 7. Therefore, it is possible to prevent the occurrence of lateral rubbing at the same time as the presence of a ratchet.

  87 to 88, when the ruler main body 1 is long, when it is lifted by an arch portion or a handle, the whole may be damaged, and a reinforcing rib is attached to prevent this. However, in this case, the whole may be warped due to a temperature change or the like, and a type for preventing this will be shown. A ruler body 1 shown in FIG. 87 has a configuration in which reinforcing ribs 1i and 1i are provided along both side edges of the arch portion 2, and the ribs 1i and 1i are cut at a predetermined pitch. Here, the reinforcing ribs 1i and 1i may be formed by fixing a square member or the like different from the material plate.
