Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tape measure, and more particularly to a tape measure capable of sufficiently reading the scale of a measuring tape even by the eyes of an elderly person.

[0002]

[Prior art and problems]

 As people grow older, their abilities and functions gradually deteriorate, and they lack the agility of the movements of their hands and feet, and become unable to move as they would like. In addition, not only the hands and feet, but also the eyes and other parts of the eye deteriorate, which reduces vision and makes it difficult for people to see things. Is appearing. In addition to this, hearing and thinking ability deteriorate, making it difficult to work with tools and increasing the probability of making mistakes. And, the above-mentioned deterioration in ability and function is a problem that cannot be avoided by human beings, and it will be experienced by anyone who becomes an elderly person.

A tape measure is no exception as a tool that is difficult for the elderly to use, and it is very difficult for a person whose function of feeling the brightness is deteriorated to read the scale of the measuring tape. Since the minimum width of the scale of the measuring tape is 1 mm, the elderly person who sees darker than usual looks like a row of scales, for example, each minimum scale is black. When displayed with, it means that each row of scales looks like a black strip. For this reason, when an elderly person measures the dimensions using a tape measure, there were many dimensional measurement errors due to the difficulty of reading the scale on the measuring tape.

For this reason, it was conceivable to use a tape measure with an illuminator for use in a dark place, but the illumination of this tape measure simply illuminates the surface of the measuring tape so that the scale can be read. In the daytime, the scale could not be illuminated clearly, and the light from the illuminator was reflected on the surface of the measuring tape, and the reflected light returned it, making it difficult to see the scale.

[0005]

【Purpose】

 The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a tape measure capable of easily identifying each graduation of the minimum width of the measuring tape.

[0006]

[Means for solving the problem]

 The gist of the present invention is to provide a measuring tape, an urging means for urging the graduated measuring tape in the winding direction, a winding drum for winding the measuring tape, and a tape measure having a case for accommodating them. In this case, the surface of the measuring tape is coated with fluorescent paint and the scale is marked, and an illuminator that illuminates the surface on the scale side of the tape is installed near the measuring tape entrance and exit of the case. It is what

As the fluorescent paint for coating the surface of the measuring tape, a commercially available one may be used, and the paint color is not particularly limited as long as it can enhance the distinctiveness of the scale. . Then, not only the surface of the measuring tape, but also the scale or the numbers indicating the dimensions may be colored with fluorescent paint instead of ordinary paint. Further, the outer circumference of the entire measuring tape manufactured by the above method may be covered with a transparent resin or the like.

The light source of the illuminator that illuminates the scale-side surface of the measuring tape may be a miniature bulb or a general light emitting diode, but it is preferable to use a high brightness type light emitting diode. In that case, the shape, number, and emission color of the light emitting diodes are not particularly limited.

[0009] An illuminator including a miniature light bulb or a light emitting diode as a light source can be formed integrally with a tape measure case, or an illuminator formed as a separate body can be pivotally attached to the tape measure case to be freely retractable. Any structure may be used.

As a power source for causing the light source to emit light, a battery which is generally commercially available may be used, but it is preferable to use a button type battery. Then, the battery accommodating portion may be provided in the illuminator or the tape measure case.

The power switch of the illumination may be provided on the illuminator or the tape measure case, and the installation site is not particularly limited. However, depending on whether the measurement tape is taken in or out, the illumination power switch is turned on and off. A switch for turning the device on and off may be provided. In this case, a small switch that serves as a power switch or a switch that uses a conductive leaf spring is installed at the measuring tape inlet / outlet inside the tape measure case, and the shock absorbing damper of the hook at the end of the measuring tape or the hook when the measuring tape is wound. Is used as a power switch for turning on and off the power switch, the switch turns on when the measuring tape is pulled out from the tape measure case, and turns off when the tape is stored in the tape measure case. It may be a structure that can be performed.

The hook at the end of the measuring tape is for preventing the entire measuring tape from being wound into the case by the biasing means, and the hook is necessarily elastically attached to the inlet / outlet of the measuring tape of the case. It engages. In the present invention, by utilizing this, when the measuring tape is stored, the hook at the end of the measuring tape comes into contact with it, and when the measuring tape is pulled out, the hook separates from the measuring tape. Set up.

[0013]

[Action]

 The tape measure of the present invention is configured as described above.When the measuring tape is pulled out, the illuminator switch is turned on to illuminate the measuring tape. The tape surface emits light as it is illuminated by light. Therefore, the measuring tape surface looks brighter, and even the visually impaired can easily perform the measurement. Then, the scale marked with ordinary paint on the measuring tape appears darker as if the color had more depth, which makes the boundary between the color of the measuring tape and the color of the scale clearer.
