Description

  This invention belongs to a stationery. It is a ruler that allows cutting to be performed safely and easily on a ruler that draws lines. Provided is an invention characterized by ease of use, in which a number of ways including right-handed and left-handed correspondence, line drawing, cutting, and storage form are made possible and made into a single structure.

According to Patent Document 1 (cutting ruler), there is a technique for preventing a similar injury by inserting a magnet into a prismatic tube and cutting it by attracting a cutter. Protrusions are installed, and the shape such as the magnet structure is slightly costly, and the present invention further seeks a shape that can be easily handled by schoolchildren by making the cutting ruler simple and reducing the manufacturing cost. did. The present invention eliminates protrusions and makes it easy to carry like a normal ruler by making it a rectangular parallelepiped as a whole, and it is easy to accurately draw lines by the graduations on the front and rear surfaces that are thick side surfaces. By doing so, it was designed to be close to the familiar experience.
Although there is also a ruler with a protective plate (see Patent Document 2), it is excellent in that it can be cut safely, but the shape of the protective plate (2), which is a protrusion, appears on the surface, unlike the present invention. Therefore, since the possibility of being caught by an object is also visible, the present invention exerts a characteristic effect in that the paper can be easily cut easily by a simple operation with a shape close to a normal ruler.
Although patent document 3 reference (ruler with a guard plate) can also protect a hand from a knife, there is a projection such as a guard plate (4) provided for the ruler (1), and the guard plate end is chamfered. Although it does not get caught somewhat, like the patent document 2, the protrusion is a form that is difficult to adapt as a normal ruler sensation. As described above, the present invention has a rectangular shape as a whole, so that it can be easily carried like a normal ruler in terms of design and handling.
As the shape of Patent Document 4 (ruled ruler), a scale is written around a substantially prismatic shape to increase the thickness (24). There is a difference in effect. Since the shape is invented exclusively for scribing, and if it is used for cutting, the top surface (22) corresponding to the width of the scoring ruler is insufficient as a shape width that can be pressed by a hand, a finger, etc. Since the ruler also serves as a means of exerting an injury prevention effect, it has a shape that is easy to hold safely with hands and fingers, and it is difficult to fall down stably by providing a large width, so that it has a single rectangular parallelepiped Was provided with a thickness. In addition, the integrated shape with a scale on the whole is a single type, it has a normal ruler's feeling of use, and also serves as a line drawing cutter. Yes.
With reference to Patent Document 5, there is a ruler for a sleeve (29) (FIG. 7) that is a hollow shape that wraps an eraser, which is convenient, but this is mainly a paper tube shape, and the eraser is united. Therefore, in the present invention, a hollow metal is mainly used, and the minimum use of a writing instrument is provided for cutting that is extremely strong against water and impact. Thereby, it has differentiation from patent document 5, and can provide a convenient point of portable use.
There is also a shape of storing one writing tool (7) in the linear groove portion (4) by the sandwiching portion (5), which is referred to as actual reference 6 (writing tool storage ruler). The holding portion has a limit in the amount of storage, and it takes time and effort to pinch one pen. Quantitatively, according to the present invention, several pens or several cutters can be accommodated depending on the width and length of the ruler, and there is no trouble of pinching. Even if compared with the present invention, the scale (3) corresponding to the side surface of the actual document 6 has a curve toward the upper part in the shape as the cutting, so that there is a possibility that the blade may run on the cutting.
There is also a reference to actual document 7 (cutting ruler), which is tubular, but is not for storage purposes and does not come with a lid. In addition, it is possible to avoid the rise of the blade, but compared with the present invention, the ruler has the scale as a whole, but it is not written on the side part, and the feeling of use is cut with a normal ruler. Because it is not a sense, it is insufficient as a ruler. In order to improve this point, it is possible to provide a normal ruler shape as a feature such as storage and carrying surface with the lid of the present invention attached, and accurate line drawing with scales as a whole.

Detailed Description of the Invention

  The present invention solves the problem that the cutting blade rides on the ruler, can handle right-handed and left-handed with a single ruler, and can be easily accommodated by anyone who can store pens, cutters, etc. in the ruler Is related to the ruler.

Means for solving the problem

  A ruler body that is hollow inside and has a rectangular parallelepiped, an opening formed on the end surface of the ruler body, and a concave and convex groove provided on the upper and lower surfaces of the rubber provided in the opening to provide a frictional action, and an insertion portion A lid provided with a core rod (G) or a groove-free lid made of a material that causes a frictional action, and a scale provided on the upper surface, the lower surface, the front surface, and the rear surface of the ruler body. A cutting ruler.

  This ruler mainly uses, for example, aluminum or stainless steel that uses a material that is difficult to lose against the blade. A cuboid tube is cut and adjusted to an appropriate length to enable storage and portability, and a scale is added to the ruler. The shape is a single rectangular parallelepiped so that everyone can use it in a normal manner. In this respect, the invention is differentiated from the inventions 1 to 7 referred to in the background art, and has a practical structure in which the advantages of the background art are combined and applied.

Effect of the invention

  Conventionally, a relatively thin ruler of 5 mm or less is often used as a tool for cutting with a knife such as a cutter knife, and there has been a drawback in that an example of a blade on the ruler or a risk of injury. In addition, there is the trouble of drawing with a normal thin ruler, placing it on a thick board and cutting again. Overcoming that, adding thickness to the side of the cutting ruler. This avoided the danger of the blade riding on the ruler. As described above, it is a ruler in which a thickness is added to the front rear surface serving as a side surface portion. The action of acting as a shield on the side can prevent the blade from climbing up. By marking a scale on the front rear surface of the side surface portion, it becomes a mark for accurate line cutting. The cutting ruler can be applied in the form of a circle, etc. The ruler body is hollow. Mainly, the rectangular parallelepiped is convenient to store and carry a set of pens and cutter knives. Moreover, there is a lid (F) for this cutting ruler, and rubber (J) is used. On the rubber surface, there are an object in which concave and convex grooves run vertically or horizontally, and a flat object using a material having a frictional action. Due to the frictional action of the rubber, the ruler is slightly prevented from being displaced by holding the ruler by hand. Further, in the type in which two lids (F) are inserted into a ruler having both ends of the tail (a, i) open, the action of preventing the cutting ruler from shifting is more effective. Since this cutting ruler is intended to be a single structure and to avoid the blade climbing, it can be inferred that it is necessary for schoolchildren to use it easily and safely. A cutting ruler with a short ruler of 20 cm to 30 cm is optimal for carrying. In addition, the cutting ruler of the present invention can be easily applied and used by increasing the width and length of the cutting ruler.

  Since the inch method (C) and the centimeter method (C1) on the (A1) and (A2) planes are written so as to be connected to the front rear surfaces (B1, B2) of the side surface portions (B), it is precisely Drawing and cutting are possible. Since the scale is marked on the top and bottom surfaces, it supports right-handed and left-handed. 4 is used when drawing a centimeter with right-handedness, and (A2) in FIG. 5 is used when drawing a centimeter with left-handedness. When using in inches, the right-handed is (A2) in FIG. To use inches on the left, use (A1) in FIG. Provides a ruler that can be cut safely and simply used, including storage.

  The ruler body (A) has a hollow (E) inside and a rectangular parallelepiped, and has openings (U) formed at both ends of the ruler body (A) or tail (A). The cutting ruler (A) is divided into an inch and a centimeter scale (C, C1) from the upper surface (A1) to the front rear surface (B1, B2) and the lower surface (A2) of the side surface (B). It is written so as to be sandwiched between the upper surface and the lower surface. The width of the ruler is a width that can be easily pressed by a hand such as a supporting finger, but it is not necessary to determine it strictly, but it is 3 cm or more. As a guideline for the thickness of the ruler side surface (B), the ruler is usually 5mm or more because there are many rulers up to 5mm, and it is 5mm or more in order to avoid blade riding. The cutting ruler has an inner diameter of 9 mm, and the average diameter of the pencil is about 8 mm. Therefore, it is a guideline considering the minimum thickness for storage. The thickness of the cavity (E) of 9 mm is about 1 cm of the outside thickness, and the thickness of the periphery is safe and the cutting feeling is good, so that it is possible to substantially avoid the ride of the cutter.

  Since this ruler is provided with a cavity (E) which is a rectangular tube serving as a storage space, about 2.5 cm or less is desirable as the limit of the cutting ruler and portable thickness for storing a normal simple cutter knife. Moreover, it is possible to insert a partition (H) serving as a rectangular cushion material for adjusting and cutting the cutting ruler (A) cavity (E) added to the longer length to a desired length so as to match the stored item. it can. The material (H) is urethane or rubber, but may be a cushioning material.

As an attached lid, the insertion piece of the lid (F) in which the outer surface of the rubber (J) is trapezoidal or rectangular parallelepiped, and the opening (c) of the cutting ruler (A) and the connecting surface of the lid are flattened, is opened (A) The core rod (G) that has a reduced rectangular parallelepiped angle is integrated so as to be inserted into the section (c). On the outer surface of the lid (F), there are an object in which a groove (G2) is provided to prevent displacement and an object without a groove. By type, (A) Covering the main body and the opening (c), which is a commonly used type, and a lid with a clamping part (I2) made of plastic or the like in a rectangular parallelepiped cylinder (I) may be used. Further, the closing portion (d) is a method of closing by welding.

  The cutting ruler described above was performed on commonly used paper. Thin paper can be cut without problems and can be safely implemented. Although it is necessary to add the strength of the hand that supports both hands and the cutting force to the cardboard, it was normally possible to cut safely and accurately. Of course, it is a manual purpose unlike a machine, so it requires careful attention to the person who cuts it, but the feeling of security for cutting is significantly higher than that of a normal several millimeter ruler. The ease of handling is drawing and cutting, and there is no difference from a normal ruler because it is simple without protrusions, and there is a stable feeling of use. In addition, the lid (F) with the groove (G2) is provided with concave and convex grooves on the rubber surface and above and below, and has a frictional action, so it is possible to prevent a slight deviation by pressing the ruler by hand. Install and use. The lid (I) is used after being removed.

  This cutting ruler is intended for the simple structure described above, and the scale is written only on one side and the side, and as a non-storage type, even in a rectangular parallelepiped that does not use a lid, the manufacturing cost and the processing effort Production can be reduced. It can be applied with or without storage function. A wide range of usage can be envisaged due to the advantage of being portable and safe to cut.
