(Structure of a tape measure according to an embodiment of the present invention)
Hereinafter, the tape measure according to the embodiment of the present invention will be described with reference to FIGS. 1 to 7.

The tape measure 1 according to the present embodiment has a long member 21 housed in a wound state in the case 11. The case 11 has a plate-shaped vinyl chloride lid 12 and a heavy box-shaped or container-shaped vinyl chloride container 13, and the lid 12 covers the container 13 to form the case 11. .. The lid 12 has screw holes (not shown). Then, a screw (not shown) is screwed into the screw holes 14a and 14b of the container 13 shown in FIGS. 2 and 3 to fix the lid 12 and the container 13. The screw (not shown above) passes through the screw hole of the lid body 12, but the head does not pass through the screw hole of the lid body 12. Therefore, from the appearance of the case 11, the head of the screw (not shown) can be seen.

The long member 21 is a polypropylene strip-shaped member having a width dimension of 10 mm and a thickness of 0.1 mm. The long member 21 is urged in the case 11 in the winding direction M by the mainspring 22. The long member 21 enters and exits the case 11 through an elongated hole which is an entrance / exit 15 from the case 11. The mainspring 22 is a strip-shaped springy metal member having a front end 22a and a rear end 22b.

The mainspring 22 is fixed to the center of the bottom surface of the heavy box in the container 13 so as to be intertwined with the winding central shaft 16 formed so as to be integrated with the container 13. The central axis 16 has a shape in which two substantially circular end faces having a cylindrical shape are cut into two equally and the cut faces are slightly separated from each other. The tip 22a of the mainspring 22 is inserted and engaged in a gap slightly separated from the cut surface of the central shaft 16, and then wound around a cylindrical peripheral surface and entangled, and the mainspring 22 is placed on the central shaft 16, that is, a container. It is fixed to 13.

Then, the rear end 22b of the mainspring is fixed to the rear end 21a of the long member 21 with an adhesive. The front end 22a to the rear end 22b of the mainspring 22 are housed in a cylindrical container 31 made of polypropylene resin. The cylindrical container 31 has a hole 32 at the bottom through which the central shaft 16 passes. Further, the cylindrical container 31 has a notch 33a on the peripheral surface having a cylindrical shape, which is a boundary between the rear end 22b of the mainspring and the rear end 21a of the long member 21. In addition to the notch 33a, there is also a notch 33b, but in the tape measure 1 according to the present embodiment, the boundary between the rear end 22b of the mainspring and the rear end 21a of the long member 21 is arranged in the notch 33a. .. Then, the long member 21 is wound around the outer peripheral surface of the cylindrical container 31.

The long member 21 wound around the outer peripheral surface of the cylindrical container 31 has a cylindrical shape having a shape in which a part of the peripheral surface is cut off, centered on the central axis 16, which is formed so as to be integrated with the container 13. It is wound around the inner peripheral surface 17a of the portion 17 and the outer peripheral surface of the cylindrical container 31. In the state of FIGS. 2 and 3 in which most of the long members 21 are housed in the container 13, a plurality of long members 21 are provided on the inner peripheral surface 17a of the cylindrical portion 17 and the outer peripheral surface of the cylindrical container 31. It is wrapped around the circumference. The outermost and final circumference of the winding of the long member 21 is wound along the outer peripheral surface 17b of the cylindrical portion 17.

Then, the long member 21 is pulled out in the pulling direction N. At this time, in the cylindrical container 31, the outer bottom surface of the cylindrical container 31 slides with the inner surface of the container 13 along the hole 32 along the central axis 16 and rotates clockwise (FIGS. 2 and 3). ). Then, the tip 22a of the mainspring 22 engaged with the central shaft 16 is fixed, and when the entire mainspring 22 is tightened inside the cylindrical container 31, the mainspring 22 is tightened, and the winding direction of the mainspring 22 The force on M is strengthened.

When the pulling force is removed from the state in which the long member 21 is pulled out in the pulling direction N, the tightening force of the springy spring 22 is weakened, and the long member 21 is wound into the case 11 while being wound up. It is stored.

Further, the front end 21b of the long member 21 protrudes from the doorway 15 to the outside of the case 11 and is fixed to the polypropylene handle 23. Since the handle 23 has a size that does not allow it to pass through the doorway 15, the front end 21b of the long member 21 does not enter the inside of the case 11 even if it is urged in the winding direction M.

As described above, since the handle 23 has a size that does not allow it to pass through the doorway 15, even if the pulling force is lost from the state where the long member 21 is pulled out in the pulling direction N, the front end of the long member 21 The 21b does not enter the inside of the case 11.

The surface 24a of the long member 21 has a front scale 25 of the long member 21 for directly displaying the drawer length. The case 11 has a window portion 18 provided therein for displaying the information 26 described on the back surface 24b of the long member 21. The window portion 18 is formed by fitting a translucent acrylic resin plate into a rectangular hole formed on the side surface of the case 11.

Here, the information 26 is information related to the withdrawal length of the long member 21. And the information 26 has an illustration.

(Main effects obtained by the embodiment of the present invention)
As described above, the tape measure 1 according to the present embodiment is a simple configuration in which anyone can understand the configuration. Moreover, the information 26 displayed on the window portion 18 is information related to the pull-out length of the long member 21. For example, if the pull-out length of the long member 21 is such that the front side scale 25 is "3 cm", the illustration and description of "one dimension master" shown in FIG. 5 are used as information 26 on the window portion 18. Can be displayed. If the drawer length of the long member 21 is such that the front side scale 25 is "33 cm", the illustration and description of the "panda baby" shown in FIG. 6 are displayed on the window portion 18 as information 26. can do. Further, if the pull-out length of the long member 21 is such that the front side scale 25 is "20 cm", the illustration and explanation of the "African snail" shown in FIG. 7 are used as information 26, and the window portion 18 is used. Can be displayed on. In this way, the tape measure 1 can be used as a learning educational toy that replaces the length of an object with the length or height of another object to imagine other objects.

Further, in the tape measure 1 according to the present embodiment, the outermost and last circumference of the winding of the long member 21 is wound along the outer peripheral surface 17b of the cylindrical portion 17. Therefore, even if the amount of the long member 21 stored in the case 11 changes, the distance between the window portion 18 and the long member 21 is always kept constant, and the appearance of the illustration or the like from the window portion 18 is the same. Become.

(Other forms)
The tape measure 1 according to the embodiment of the present invention described above is an example of a preferred embodiment of the present invention, but is not limited to this, and various modifications can be carried out without changing the gist of the present invention. is there.

For example, the lid 12 is screwed into the screw holes 14a and 14b of the container 13 shown in FIGS. 2 and 3 using screws (not shown) that pass through the screw holes of the lid 12 (not shown). The lid 12 and the container 13 are fixed. Here, the lid body 12 and the container 13 are fixed at two places with screws, but for example, four places may be fixed. Further, the lid 12 and the container 13 may be fixed by assembling without using screws or by fixing with screws.

Further, the tape measure 1 has a lid 12 made of vinyl chloride and a container 13 made of vinyl chloride as well. The long member 21 is a polypropylene strip-shaped member having a width dimension of 10 mm and a thickness of 0.1 mm. The cylindrical container 31 is made of polypropylene resin. The handle 23 is also made of polypropylene resin. Further, the window portion 18 is made of acrylic resin. However, the material of each member is not limited to these, and the optimum material can be selected to play the role of each member. For example, the window portion 18 is preferably made of a translucent material. The case 11 can also be made of a translucent material so that the structure and movement inside the case 11 can be understood. Further, each dimension of the long member 21 can be changed as appropriate. Further, the material of the long member 21 may be glass fiber, cloth, or the like. By using cloth as the material of the long member 21, color printing of the long member 21 becomes easy. Further, the material of the long member 21 can generally be a material that breaks when pulled in the pulling direction N beyond the pulling force of a child. Here, in general, the force exceeding the pulling force by the child's force can be set to, for example, 10 kg, 15 kg, 20 kg, 25 kg, 30 kg, 35 kg, 40 kg and the like. Further, as a method of breaking the long member 21, the material of the long member 21 itself is generally selected to be broken by a force exceeding the pulling force of a child, or in a direction intersecting the pulling direction N. , The long member 21 may be provided with a thin groove or the like, or a cut may be provided.

Further, the mainspring 22 is fixed so as to engage and entangle with the central shaft 16. However, an adhesive, an adhesive tape, or the like may be used as a means for fixing the mainspring 22 to the central shaft 16. Further, the mainspring 22 may be fixed to the central shaft 16 by using an adhesive, an adhesive tape or the like after engaging and entwining with the central shaft 16.

Further, the central axis 16 has a shape in which two substantially circular end faces having a cylindrical shape are cut into two equally and the cut faces are slightly separated from each other. However, as the shape of the central shaft 16, other shapes may be adopted, such as arranging two rectangular parallelepiped columns slightly apart from each other.

Further, the cylindrical container 31 has a cylindrical notch 33a on the peripheral surface which is a boundary between the rear end 22b of the mainspring and the rear end 21a of the long member 21. However, the notch 33a is not an essential component of the tape measure 1, and can be omitted. Further, instead of the notch 33a, the boundary between the rear end 22b of the mainspring and the rear end 21a of the long member 21 may be arranged in the notch 33b. Further, instead of the notch 33a, a notch position may be provided, and a boundary between the rear end 22b of the mainspring and the rear end 21a of the long member 21 may be arranged there.

Further, the rear end 22b of the mainspring is fixed to the rear end 21a of the long member 21 with an adhesive. However, the rear end 22b of the mainspring and the rear end 21a of the long member 21 may be fixed by using an adhesive tape, a stapler, or the like instead of the adhesive.
The tape measure 1 has a configuration in which the long member 21 is stored in the case 11 in a wound state and the long member 21 is pulled out of the case 11 against the urging force urged in the winding direction M. Is. However, the urging force urged in the winding direction M is not always necessary. For example, the long member 21 once pulled out can be wound in the winding direction M by a hand tool or the like even if there is no urging force urged in the winding direction M. Further, the mainspring 22 is not essential to apply the urging force urged in the winding direction M, and a spring or the like can be used.

Further, in the tape measure 1 according to the present embodiment, the outermost and last circumference of the winding of the long member 21 is wound along the outer peripheral surface 17b of the cylindrical portion 17. That is, when the long member 21 is pulled out, it has a cylindrical portion 17 (member to be along) that allows the long member 21 to follow the surface facing the window portion 18 without changing the distance from the window portion 18. ing. However, since the cylindrical portion 17 is not an essential component of the tape measure 1, it can be omitted.

Further, instead of the cylindrical portion 17, a portion having the same function as the cylindrical portion 17 in which the portion facing the window portion 18 is parallel to the window portion 18 may be used. By making the portion facing the window portion 18 parallel to the window portion 18, the information 26 seen from the window portion 18 is made flat rather than curved as shown in FIGS. 5, 6, and 7. can do. By making the information 26 visible from the window portion 18 flat, it is easy to read when the reader hits the information 26 when the information 26 is a barcode or a QR code. Further, the cylindrical portion 17 does not have to be integrated with the case 11.

Further, the front end 21b of the long member 21 protrudes from the doorway 15 to the outside of the case 11 and is fixed to the handle 23. However, since the handle 23 is not an essential component, it can be omitted. For example, even if the front end 21b of the long member 21 that protrudes from the doorway 15 to the outside of the case 11 is double-folded or triple-folded to increase the thickness, the doorway 15 cannot be passed. good.

Further, for example, if the pull-out length of the long member 21 is a length in which the front side scale 25 is "3 cm", the illustration and explanation of "one dimension master" shown in FIG. 5 are used as information 26 for the window portion. Displayed at 18. If the pull-out length of the long member 21 is such that the front side scale 25 is "33 cm", the illustration and description of the "panda baby" shown in FIG. 6 are used as information 26, and the window portion 18 is used. To display. Further, if the pull-out length of the long member 21 is such that the front side scale 25 is "20 cm", the illustration and explanation of the "African snail" shown in FIG. 7 are used as information 26, and the window portion 18 is used. Display in.

However, these pieces of information 26 are merely examples. The information 26 displayed on the window portion 18 may be any information related to the pull-out length of the long member 21. For example, the information 26 is not limited to the illustration and the description, and may be one or more selected from illustrations, images, characters, symbols, codes, colors, barcodes, and QR (Quick Response) codes. Further, the information 26 is an information storage medium such as an RFID (radio frequency identifier) tag, and is fixed at the position of the long member 21 facing the window portion 18 according to the withdrawal length of the long member 21. It may be a thing. As a result, more information can be included in the information 26.

Here, instead of the above-mentioned illustration of the information 26, or together with the above-mentioned illustration, a QR code of a website URL (uniform resource locator) capable of displaying a large number of items having a front side scale 25 of "33 cm" is displayed. It may be a thing. If you read the QR code with a mobile terminal or the like and browse the website, you can imagine other things by replacing the length of "33 cm" with the length of more other things. Also, because the website is easy to update, it is easy to delete things that children are not interested in and add things that children are likely to be interested in.

For example, when purchasing clothing such as a shirt, the size of the clothing may be determined simply by measuring the size of the collar of the wearer. For example, if the size of the collar is 36 to 37 cm, the size of the shirt is "S", and if the size of the collar is 38 to 39 cm, the size of the shirt is "M" and the size of the collar is 40. If the size is ~ 41 cm, the size of the shirt will be "L", if the size of the collar is 42 to 43 cm, the size of the shirt will be "LL", and if the size of the collar is 44 to 45 cm, the size of the shirt will be "LL". The size will be "3L".

Thus, the correlation between the size of the collar and the size of the shirt is stronger for short-sleeved or seven-part length shirts. Employees of stores that handle such products are less likely to make mistakes if they only measure the size of the collar with a tape measure 1 and have the shirt size displayed directly on the window 18. Other examples of such clothing are socks, shoes and the like. In the case of socks, shoes, etc., measure the length from the end of the heel of the foot to the longest toe, that is, the length of the foot with a tape measure 1. Then, the size of socks, shoes, etc. can be displayed on the window portion 18.

In this way, measure the size of your collar with a tape measure 1 and display a list of shirts that can be purchased on the window 18 and shirts that are not currently in the store but can be purchased after waiting a few days. The QR code of the URL of the website may be displayed. The QR code can be read by a mobile terminal such as a smartphone of the customer or the store, the website can be browsed, and shopping can be made more convenient.

In addition, there are an extremely large number of types of mechanical parts, electrical parts, or control parts. The catalog of these parts has more than 1000 pages. Therefore, even when handling one type of part, it is often impossible to specify the correct part number without a catalog. Moreover, the product number is often different due to the difference in component dimensions. Therefore, the size of a specific part of the part is measured with a tape measure 1. Then, the product number of the part or the like can be displayed on the window portion 18.

In addition, some courier companies determine the delivery charge based on the sum of the three sides of the vertical dimension, the horizontal dimension, and the height dimension when the package is a rectangular parallelepiped. Therefore, the sum of the dimensions of the three sides is measured with a tape measure 1. Then, the shipping fee can be displayed on the window portion 18. At this time, instead of displaying the shipping fee on the window portion 18, if the barcode or the like of the shipping fee is displayed on the window portion 18 and the barcode or the like is read by the barcode reader of the register, the cashier can be omitted. , Typing mistakes can be prevented.

Further, the long member 21 may be composed of a so-called "bending display". As a result, the information 26 displayed on the window portion 18 can be converted into a moving image or the like. In addition, the unit of the scale of the tape measure 1 (feet display, metric display, etc.) can be easily changed.

Further, the tape measure 1 may be provided with a communication means such as Bluetooth (registered trademark) or Wi-Fi. As a result, the tape measure 1 can send information on the length of the long member 21 pulled out to a mobile terminal device such as a smartphone, a personal computer, or the like for display or the like.

Further, the tape measure 1 may be provided with a display of an electronic device in place of or in addition to the window portion 18. As a result, the tape measure 1 can display more detailed information of the information 26 on the display.

Further, the tape measure 1 acquires not the length of pulling out the long member 21 but the speed of pulling out by the sensor included in the tape measure 1, and the expression of what is displayed can be changed according to the speed. For example, the pull-out speed acquired by this sensor makes it possible to change the display effect of an electronic device.
