JPH062103U - Tape measure rule - Google Patents

Abstract

(57) [Abstract] [Purpose] It is possible to make a mark on the rule surface and erase the mark, and still obtain a rule of a tape measure without reflection of light from the rule surface. [Structure] The ruled surface was made into a finely rough surface by a finishing coating agent containing inorganic ultrafine particles that do not impair transparency.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a tape measure, and in particular to the rule of a tape measure.

[0002]

[Prior art]

 Conventionally, the rule of the tape measure is that, as shown in FIGS. 3 and 4, the surface of the core material 2 coated with the white coating 1 is provided with the measuring scale 3 and the measuring unit number (not shown), so that the whole finish is transparent. The rule is that the surface is smoothed with a buff coating 4.

However, even if such a rule tries to make a mark on the surface of the rule with a writing instrument such as a pencil, the surface is too smooth to make a mark, and it is possible to make a mark. However, there was a problem in that it was easily erased by lightly touching another object.

Further, it has been pointed out that there is a problem in that the scale is difficult to read due to the reflection of light in a specific direction on the smooth rule surface.

[0005]

[Problems to be solved by the device]

 The purpose of this invention is to obtain a rule of a tape measure which can mark a rule surface with a pencil or the like and can erase the marked mark, and yet does not reflect light from the rule surface.

[0006]

[Means for Solving the Problems]

 The surface of the rule was made into a fine, rough surface with a finishing coating agent containing inorganic ultrafine particles that did not impair transparency.

[0007]

[Action]

 By mixing ultrafine particles that do not impair the transparency of silica, glass, etc. into the finish coating agent, the rule surface is made a fine rough surface, so make a note of the actual measurement value etc. on the rule surface with a writing instrument It becomes possible to mark it, and not only can it be easily erased by wiping it strongly, but it also reduces the reflection of light and makes it easier to read the scale and numbers.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The rule of the tape measure of the present invention shown in FIGS. 1 and 2 is that after the measuring scale 7 and the measuring unit number (not shown) are attached to the surface of the core material 6 to which the white coating 5 is applied, The entire surface is coated with a transparent finishing coating agent 9 containing 5 to 15% by weight of inorganic ultrafine particles 8 that do not damage the surface, for example, ultrafine particles such as silica and glass. It was possible to obtain the tape measure rule of the present invention having a fine rough surface.

[0010]

[Effect of device]

 As described in detail above, the rule of the tape measure of the present invention is that the rule surface is made into a fine rough surface by the finish coating agent containing the ultrafine inorganic particles that does not impair the transparency. It is possible to make a mark by entering the actual measured value using, and it will not be erased by touching another object lightly, and the rule surface will be extremely fine due to the ultrafine inorganic particles. Since irregularities are formed and the surface becomes rough and diffusely reflects light, it has a matte appearance and is easy to read scales and numbers.
