Description

  The present invention relates to a ruler such as a line drawing or a ruler or a protractor, and more particularly to a ruler with a non-slip mechanism for preventing the position of the ruler from shifting when a line is drawn according to the ruler.

  Conventionally, when drawing a line by aligning a ruler on a paper such as a drawing, a hand is generally held by a dominant hand, and the line is drawn by pressing the ruler with the opposite hand (non-dominant hand). When handling a ruler with a non-dominant hand, the ruler may slip and slip because it is not as dexterous as the dominant hand.

  A ruler with a non-slip mechanism that copes with the ruler slipping has been proposed. For example, Patent Document 1 discloses a ruler having a non-slip member. According to this ruler, the friction body assembled to the ruler body is provided, and the curved ruler body is pressed toward the sheet side to be compressed and deformed, and the friction body comes into contact with the sheet. As a result, the ruler can be made difficult to slide against the paper.

  Patent Document 2 discloses a ruler with a non-slip mechanism. According to this ruler with an anti-slip mechanism, a concave portion is provided in the ruler body to form a thin portion having elasticity, and an adhesive film is formed on the bottom surface side of the thin portion. Thus, the thin portion can be pressed to bring the adhesive film into contact with the paper so that the ruler can hardly slide.

  Next, embodiments of the present invention will be described with reference to the drawings.

  With reference to FIG.1 and FIG.2, the structural example of the ruler 100 with a non-slip | skid mechanism as 1st Embodiment is demonstrated. The ruler 100 with a non-slip mechanism includes a ruler body 1, cut grooves 2a and 2b, a pressing plate 3, a scale portion 4 and a non-slip portion 5 (see FIG. 2B). The ruler body 1 is formed from a material such as resin, metal, bamboo, or the like. A scale portion 4 is provided at one end of the ruler body 1 in the longitudinal direction. As an example, the scale part 4 has a scale of 15 cm in units of 1 mm. Of course, the scale part 4 is not limited to a 15-cm format in 1 mm units, and scales may be engraved in 2 mm units or 5 mm units. Furthermore, the scale part 4 may have a length of 15 cm or more, or may have a length of 15 cm or less.

  A pressing plate 3 is provided at the center of the ruler body 1. The pressing plate 3 is formed by cutting a predetermined portion of the flat ruler main body 1, and the surface is pressed and bent. For example, the pressing plate 3 is surrounded by a cut groove 2a formed by cutting the ruler body 1 in the longitudinal direction, and cut grooves 2b and 2b formed by cutting in the short direction from both ends of the cut groove 2a. This area In this example, the cut groove 2a is formed by cutting in a substantially straight line along the scale portion 4, and the cut grooves 2b and 2b are formed on the short side of the ruler body 1 substantially vertically from both ends of the cut groove 2a. It is cut and extended in the direction. The width of the cut groove 2a is about 0.5 mm to 1.0 mm. The pressing plate 3 bends around a connecting portion 2c that connects the respective leading ends of the cut grooves 2b and 2b. In this example, substantially circular relief portions 2d and 2d having a diameter larger than the width of the cut groove 2b are formed at the respective ends of the cut grooves 2b and 2b. The relief portions 2d and 2d relieve stress generated when the surface P of the pressing plate 3 is pressed and bent.

  The anti-slip portion 5 shown in FIG. 2B is provided on the back surface Q side of the pressing plate 3 and is formed of a material having a high frictional force due to an adhesive material such as rubber. For example, the anti-slip portion 5 is formed by silk-screen printing liquid silicon rubber on the back surface Q side of the pressing plate 3. In this example, the silicon rubber 5a is printed in a dot shape (bar shape) so that the anti-slip portion 5 forms an uneven surface. Thereby, since the anti-slip mechanism of the ruler can be simply configured, the manufacturing cost can be reduced. Of course, a sheet-like silicon rubber may be affixed to the back surface Q side of the pressing plate 3, or the silicon rubber may be printed in a solid form on one side. The thickness of the non-slip portion 5 is about 0.05 mm to 0.2 mm.

  Next, an operation example of the ruler 100 with the anti-slip mechanism will be described with reference to FIGS. 3A and 3B. The pressing plate 3 shown in FIG. 3A is formed to warp upward with respect to the horizontal position M of the ruler body 1. For example, the pressing plate 3 is formed to warp upward so as to protrude about 0.1 mm to 0.3 mm with respect to the horizontal position M. Thereby, there is a gap S between the anti-slip portion 5 provided on the back surface Q side of the pressing plate 3 and the placement surface N on which the ruler body 1 is placed. Accordingly, since the anti-slip portion 5 does not come into contact with the placement surface N, the ruler body 1 can smoothly slide on the placement surface N.

  The pressing plate 3 shown in FIG. 3B is pressed in the direction of arrow R, bends downward about the connecting portion 2c, and is substantially horizontal with respect to the horizontal position M. At this time, the anti-slip portion 5 provided on the back surface Q side of the pressing plate 3 is pressed against the placement surface N to generate a frictional force, so that the ruler body 1 can be fixed to the placement surface N. Therefore, a line can be accurately drawn by applying a writing instrument or the like to the scale portion 4.

  When the pressing force in the direction of arrow R applied to the pressing plate 3 is released after drawing the line, the pressing plate 3 rises around the connecting portion 2c due to the effect of the leaf spring, and reaches a horizontal position M shown in FIG. 3A. On the other hand, it returns to a position that is warped upward.

  Thus, according to the ruler 100 with the anti-slip mechanism according to the present invention, the anti-slip portion 5 having a high frictional force is provided on the back surface Q side of the pressing plate 3 that is bent by pressing the front surface P. With this configuration, when the pressing plate 3 is pressed, the anti-slip portion 5 is pressed against the placement surface N on which the ruler body 1 is placed, and a frictional force is generated, thereby fixing the ruler body 1 to the placement surface N. become able to. Further, by providing the anti-slip part 5 on the back surface Q side of the pressing plate 3, the ruler anti-slip mechanism can be simply configured, and thus the manufacturing cost can be reduced.

In this example, a case where the paper is cut linearly by the cutter 6 will be described. In this case, the ruler 100 with a non-slip mechanism shown in FIG. 4 is slid on the paper and moved to a position where the cut groove 2a is cut. After the movement, the pressing plate 3 is pressed in the direction of arrow R, and the anti-slip portion 5 provided on the back surface Q side of the pressing plate 3 is pressed against the sheet. As a result, a frictional force is generated between the anti-slip portion 5 and the paper, and the ruler body 1 can be fixed to the paper. After fixing the ruler body 1 to the paper, the blade 6a of the cutter 6 is inserted into the cut groove 2a, and the blade 6a of the cutter 6 runs along the cut groove 2a. In this way, the cut groove 2 a may be used for cutting paper with the cutter 6.

  Next, a ruler 100A with a non-slip mechanism as a second embodiment will be described with reference to FIGS. 5A and 5B.

In this example, a stepped portion 7 is provided on the back surface Q side of the pressing plate 30 at a position one step higher than the placement surface N. An anti-slip portion 50 is provided on the stepped portion 7. Thereby, there is a gap S between the anti-slip portion 50 provided on the back surface Q side of the pressing plate 30 and the placement surface N on which the ruler body 1A is placed. Accordingly, since the anti-slip portion 50 does not contact the placement surface N, the ruler body 1A can smoothly slide on the placement surface N.

  The pressing plate 30 shown in FIG. 5B is pressed in the direction of the arrow R, bent around the connecting portion 2c, and bent downward with respect to the horizontal position M. At this time, the anti-slip portion 50 provided on the back surface Q side of the pressing plate 30 is pressed against the placement surface N to generate a frictional force, so that the ruler body 1A can be fixed to the placement surface N. Therefore, a line can be accurately drawn by applying a writing instrument or the like to the scale portion 4.

  When the pressing force in the direction of arrow R applied to the pressing plate 30 is released after drawing the line, the pressing plate 30 rises around the connecting portion 2c due to the effect of the leaf spring, and reaches a horizontal position M shown in FIG. 5A. Return. In this way, the anti-slip portion 50 may be provided in the step portion 7 that is one step higher than the placement surface N.

  Next, a ruler 100B with a non-slip mechanism as a third embodiment will be described with reference to FIGS. 6A and 6B. The main configuration of the ruler with anti-slip mechanism 100B from the ruler with anti-slip mechanism 100 shown in FIG. 2A and the like is the position of the cut grooves 20a, 20b, and 20b that form the pressing plate 31. In this example, the cut groove 20a is formed by cutting in a substantially straight line along the side end 8 of the ruler body 1B, and the cut grooves 20b and 20b are formed substantially vertically from both ends of the cut groove 20a. It is cut and extended toward the scale part 4. The pressing plate 31 is a region surrounded by the cut groove 20a and the cut grooves 20b and 20b, and bends around a connecting portion 20c that connects the respective ends of the cut grooves 20b and 20b. The pressing plate 31 shown in FIG. 6A is formed so that the cut groove 20a side is warped upward with respect to the horizontal position of the ruler main body 1B.
