Description

  The present invention mainly relates to a ruler called a straight scale, such as a bamboo scale.

  One of the first scales used by elementary school first graders is the bamboo ruler, which generally has a total length of 30 cm. Further, as a straight scale, for example, in Patent Document 1, there is one that makes it easy to visually register a center point by coloring a predetermined area on the left and right sides of a straight scale surface.

JP-A-8-145601

  The first time elementary school children draw a straight line with a pencil, etc., using a straight scale (bamboo measure) for the first time, the hand of the child is smaller than the size of the bamboo measure. While holding down the pencil, it does not support the bamboo ruler when pulling while pushing against the edge of the bamboo ruler, and the bamboo ruler may move by being pushed by the pencil, making it impossible to draw a straight line There is a problem.

  Here, as in the example shown in the above-mentioned Patent Document 1, there are things that have been taken into consideration in the straight scale, but there are no things that have taken into consideration the handling characteristics at the time of use to prevent the displacement movement when drawing a straight line. .

  In view of such circumstances, an object of the present invention is to provide a ruler that hardly moves during use.

  The present invention is characterized in that a non-slip member is provided on the lower surface of the main body.

  In this configuration, if the ruler is placed on the paper on the desk and pressed from above with one hand, the anti-slip member will not slip on the paper, so one of the two long sides of the ruler will be When drawing with a pencil or the like, there is no risk that the ruler will be moved by being pushed by the pencil.

  In other words, it is not necessary to press the ruler with a strong hand, so even if it is used by elementary school children whose elementary hands are still small, the ruler is difficult to move.

  Preferably, the anti-slip member is provided continuously or discontinuously over the entire length in the longitudinal direction of the main body in a region near one of the two long sides on the lower surface of the main body. be able to.

  In this configuration, since the anti-slip member is provided continuously or discontinuously over the entire length in the longitudinal direction near one of the two long sides on the lower surface of the main body, when the ruler is placed on the paper, It can be stabilized on paper without rattling. In addition, most of the area of the lower surface of the main body of the ruler is exposed. Therefore, the lower surface of the main body can be effectively used, for example, a tape that describes user information such as grade, group, name, etc. can be arbitrarily attached to the exposed area.

  Further, the anti-slip member may be provided at two locations near the two short sides on the lower surface of the main body.

  Even in this configuration, the ruler is not rattled when placed on the paper, and can be stabilized on the paper. In addition, most of the area of the lower surface of the main body of the ruler is exposed. Therefore, the lower surface of the main body can be effectively used, for example, a tape that describes user information such as grade, group, name, etc. can be arbitrarily attached to the exposed area.

  Preferably, the anti-slip member may be a tape made of a material that is difficult to slip against a desk or paper and is affixed to the lower surface.

  In this configuration, the anti-slip member can be provided in the ruler relatively easily, so that the productivity is excellent.

  The ruler according to the present invention is very easy to use because it is difficult to move when a line is drawn on paper.

It is a perspective view which shows the state looked up from diagonally downward in other embodiment of the ruler which concerns on this invention.

  BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings.

  1 to 3 show an embodiment of the present invention. In the figure, reference numeral 1 denotes the entire ruler.

  The ruler 1 is a straight scale made of a belt-like plate. The material of the ruler 1 is bamboo, wood, synthetic resin, metal or the like.

  The upper surface of the main body 2 of the ruler 1 is a curved surface that rises so as to bend in the lateral direction. On the upper surface of the main body 2, a scale indicating the length is engraved in a region near one of the two long sides.

  An anti-slip member 3 is provided on the lower surface of the main body 2 of the ruler 1. The anti-slip member 3 is made of a single thin tape, and is attached to the lower surface of the main body 2 in a region near one of the two long sides over the entire length in the longitudinal direction.

  The anti-slip member 3 made of this tape is formed of a material (for example, rubber or synthetic resin) having a predetermined frictional resistance against a desk or paper, and on the surface facing the lower surface of the main body 2 Adhesive is attached.

  As shown in FIG. 2, the surface of the anti-slip member 3, that is, the exposed surface, is provided so as to intersect with the linear protrusions 4 or in the form of a dot matrix, thereby providing a desk or paper. It is possible to further increase the frictional resistance against.

  With the ruler 1 provided with such an anti-slip member 3, the anti-slip member 3 is less likely to slip on the paper by simply pressing it with one hand while the measure 1 is placed on the paper on the desk. Therefore, when drawing with a pencil or the like along one of the two long sides of the ruler 1, there is no possibility that the ruler 1 will be displaced by being pushed by the pencil. Accordingly, for example, even if a child of an elementary school lower grade who has a small hand still uses the ruler 1, it is difficult for the ruler 1 to move.

  Further, as in this embodiment, when the anti-slip member 3 is attached as a long and narrow tape to the lower surface of the main body 2 over the entire length in the longitudinal direction near one of the two long sides, When the ruler 1 is placed on the paper, it does not rattle and can be stabilized on the paper. Further, since most of the area on the lower surface of the main body 2 of the ruler 1 is exposed, for example, as shown in FIG. 3, a tape 5 on which user information such as grade, group, and name is written in the exposed area is shown. The lower surface of the main body 2 can be effectively used, for example, it can be arbitrarily attached.

  Furthermore, in this embodiment, since the anti-slip member 3 is affixed to the lower surface of the main body 2 as a tape made of a material that is difficult to slip against a desk or paper, the anti-slip member 3 is relatively easily attached to the ruler 1. It becomes possible to provide it, and it is excellent in productivity.

  The present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the utility model registration request and within the scope equivalent to the scope.

  (1) In the above embodiment, the anti-slip member 3 is a tape or the like. However, it is possible to use a coating agent obtained by coating rubber or synthetic resin.

  (2) In the above embodiment, an example in which the anti-slip member 3 made of tape is simply pasted on the lower surface of the main body 2 of the ruler 1 is described, but the present invention is not limited to this.

  For example, as shown in FIG. 4, the installation region of the anti-slip member 3 may be recessed on the lower surface of the main body 2, and the anti-slip member 3 may be installed in the recess 6. However, at that time, it is preferable that the anti-slip member 3 protrudes from the lower surface of the main body 2 rather than the opening of the recess 6.

  (3) In the above embodiment, an example in which the non-slip member 3 is attached as a single elongated tape to the lower surface of the main body 2 over one of the two long sides and over the entire length in the longitudinal direction. However, the present invention is not limited to this.

  For example, as shown in FIG. 5, the anti-slip member 3 is formed as three elongated tapes, and these are provided discontinuously over the entire length in the longitudinal direction near one of the two long sides on the lower surface of the main body 2. It is possible. The number of installation positions of the anti-slip member 3 is arbitrary.

  Further, for example, as shown in FIG. 6, the anti-slip member 3 can be installed at two locations near the two short sides on the lower surface of the main body 2. Also in this case, when the ruler 1 is placed on the paper, it is not rattled and can be stabilized on the paper. Further, the anti-slip member 3 has an elongated strip shape, but may be a wide rectangle, a square, an arbitrary shape such as a circle or an ellipse.

  The present invention can be suitably used as a ruler such as a straight scale including a bamboo scale.
