Abstract

PURPOSE: To temporarily fix a ruler by notching appropriate parts of a top face of a ruler into the appropriate number of grooves, embedding substrates having elasticity and non-slip members fixed to their bottom faces in the notched grooves, and pressing the upper parts of the substrates lightly. CONSTITUTION: Nearly at a central part and right and left end parts on a top face of a ruler 1, elliptic notched grooves 2 are formed and elliptic housing holes 4 for housing non-slip members 5 are formed nearly at the central parts in the notched grooves 2. In each notched groove 2, a substrate 3 formed of an elastic synthetic resin and formed into almost the same shape as that of the notched groove 2 is embedded, stuck, and fixed. To the bottom face of the substrate 3, the non-slip member 5 formed of a rubber material and a magnet and formed into almost the same shape as that of the housing hole 4 is stuck and fixed by an adhesive. When the ruler 1 is in use and non-slip function is necessary, the upper part of the substrate 3 is pressed lightly so as to bring the non-slip member 5 into contact with a paper, so that the ruler 1 is temporarily fixed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruler used for drawing a line on a paper surface or for breaking a paper material with a cutter knife or the like for drawing.

[0002]

2. Description of the Related Art Conventionally, a ruler used for drawing or the like is not usually provided with an anti-slip member. However, the actual exploitation Sho-62-90188 and the actual exploitation 3-68494
As shown in Japanese Patent Publication No. JP-A-2003-115, a rubber material is attached to the underside or inside of the ruler, or as in JP-B-63-25193, a substrate having an adhesive layer that can be repeatedly attached is fixed to the underside of the ruler. In some cases, the ruler is temporarily fixed on the paper surface with an adhesive layer.

[0003]

Conventionally, a ruler that has been generally used has not been devised to prevent slipping. Therefore, when drawing a line such as drawing, the ruler slips to form a correct line. It was difficult to pull. Also, in the case of a ruler in which a rubber material is attached to the underside or inside of the ruler, only one type of anti-slip member is provided, so it is optimal for the desk or drafting table on which paper is placed, for example. It was not possible to select and use the anti-slip member properly. In addition, the ruler, which has an adhesive layer with repeatable adhesiveness on the lower surface of the ruler, will stain the paper when the adhesive force of the adhesive layer used is too strong or too weak for the paper quality. However, there is a problem in that the adhesive property of the adhesive layer is deteriorated when it is repeatedly used. The present invention is a ruler which solves these drawbacks of the prior art, exerts an anti-slip effect when anti-slip is required, and can slide when anti-slip is not required. It is intended to provide a ruler that can be formed of two kinds of materials and can be used properly according to the usage state.

[0004]

According to the present invention, an appropriate number of notched grooves are engraved at appropriate places on the upper surface of a ruler, and a storage hole for accommodating an anti-slip member is formed in the lower surface of the notched groove. The ruler is a penetrating ruler, and a non-slip member formed in a shape slightly smaller than the internal shape of the storage hole is fixed to the lower surface of a separately provided elastic substrate to fix the substrate. The anti-slip member is embedded in the cutout groove so that the anti-slip member can be operated in the storage hole, and the anti-slip member is composed of a rubber material and a magnet.

[0005]

[Function] When the ruler is temporarily fixed and used, the ruler is placed on the surface of the paper with the surface where the storage hole storing the anti-slip member is open facing down, and slipped through the elastic substrate. When the stopper member is lightly pressed, the anti-slip member comes into contact with the paper surface, so that the ruler can be temporarily fixed at that position. When the ruler needs to be slid and used, the ruler may be used as it is without performing the above operation, or the ruler may be turned upside down and used with the magnet provided on the upper surface.

[0006]

An embodiment of the present invention will be described with reference to the drawings.
The ruler 1 is made of a slender synthetic resin having a scale on one edge, and the upper surface of the ruler 1 is located near the center and the left and right end portions of the blank portion where the scale is not formed. Elliptical notched grooves 2 are engraved at three locations, and an elliptical accommodation hole 4 for accommodating an anti-slip member, which will be described later, is provided at a substantially central portion of the notched groove 2 with a ruler 1. Is formed so as to penetrate through the inside and be opened. The substrate 3 provided as a separate body is made of a synthetic resin having elasticity, and its shape is substantially the same as that of the cutout groove 2 so that it can be attached and embedded in the cutout groove 2. The same shape is formed, and after the substrate 3 is adhered and embedded in the notch groove 2, the upper surfaces of both are formed to be the same. Further, the anti-slip member 5 formed of a separate rubber material and magnet is formed to have substantially the same shape as the storage hole 4 and to have a shape slightly smaller than the internal shape of the storage hole 4. The upper surface of the stopper member 5 and the lower surface of the substrate 3 are bonded and fixed with an adhesive or the like. The board 3 and the anti-slip member 5 formed as described above are inserted into the cutout groove 2 and the storage hole 4, respectively, and the board 3 and the cutout groove 2 are fixed to each other with an adhesive or the like to prevent slippage of the present invention. A ruler provided with a stop member is formed.

Three anti-slip members 5 used in this embodiment
There are two materials made of rubber and one made of magnet. For these anti-slip members, for example, when a desk or a drawing board used for drafting is made of wood, one made of a rubber material is used as the anti-slip member, and the desk or the drawing board is In the case of metal such as steel, if a member formed of a magnet is used as the anti-slip member, it is possible to effectively fix the ruler temporarily. The three anti-slip members may all be made of a rubber material, or all of them may be made of a magnet, and the two rulers may be provided with anti-slip members made of a rubber material and a magnet, respectively, depending on the purpose of use. You may use properly.

In the anti-slip member thus formed, the anti-slip rubber material and the magnet are formed in a shape slightly smaller than the storage hole 4, so that the lower surface thereof is smaller than the opening surface of the storage hole 4. It will be provided slightly inside, and if you are using a ruler and need to prevent slipping, if you press lightly from above the substrate 3, the slip preventing member will contact the paper in conjunction with it, The anti-slip effect can be exerted to temporarily fix the ruler. Also, if you need to slide the ruler, if the anti-slip member you are using is a rubber material, you can use it as it is without performing the above operation,
When a magnet is used, the ruler can be moved smoothly by turning the ruler upside down and using it with the magnet provided on the upper surface.

Next, another embodiment of the present invention will be described. In this embodiment, the structure in which the above-mentioned non-slip member is provided on the ruler is
Instead of forming it on only one side of the ruler, a similar structure is provided on both sides of the ruler. That is, the anti-slip member is formed on the surface of the ruler with the above-mentioned configuration,
If the non-slip member is provided in the same manner as the one formed on the front surface in the blank area on the back surface of the ruler, the same effect can be obtained by using either side of the ruler up. In this case, it is preferable that all the anti-slip members on one surface are made of a rubber material and all the anti-slip members on the other surface are magnets.

The number and shape of the notch groove, the storage hole, the anti-slip member, etc. are not limited to those of the present invention. For example, those shapes may be formed into other shapes such as quadrangle and circle. The number may be one each. Further, as long as the material of the substrate has elasticity, it may be formed by using other material such as bamboo or a thin plate of steel.

[0011]

The ruler provided with the anti-slip member of the present invention is
If the bottom surface of the non-slip member is formed slightly inside the opening surface of the storage hole formed on the bottom surface of the ruler, and if slip prevention is required during the use of the ruler, The ruler can be temporarily fixed with a simple operation by simply pressing lightly from above, and when slip prevention is not required, you can use it as it is without performing the above operation, or use it by turning the ruler upside down. Not only is it easy to operate and it is very convenient, but since one ruler is provided with two types of anti-slip members, it is possible to use different anti-slip members according to the conditions of use. It has major features.
