Description

[Detailed description of the invention] (Industrial application field) This invention is a height meter that measures the height of the human body.It displays the measured value digitally, and its overall length can be shortened and disassembled, making it convenient for transportation and storage. This invention relates to a digital display height meter with a unique structure.

(Prior Art) A height meter that measures height and digitally displays the measured value is known, for example, as disclosed in Japanese Patent Laid-Open No. 75217/1983.

This known height meter has a rod-shaped height measuring part that is sufficiently longer than the height of a normal person, a groove is formed parallel to the vertical direction in the height measuring part, and a height measuring part is arranged in the groove. The position of the upper part of a person's head is measured and detected by scanning the light emitting element, and the obtained detection value is digitally displayed on a digital display section.

Height meters that display measured values digitally have the advantage of being easy to read, allowing quick reading of measured values, and reducing the risk of misreading the values. There is.

(Problem to be solved by the invention) However, in the case of such a known height meter, the height measuring part is configured to be sufficiently longer than the height of a normal person, and the step part is fixed to the lower part of the height measuring part. Because it has a structure that cannot be separated, it is very inconvenient to transport and store. Additionally, since the position of the top of the subject's head is detected by scanning the light emitted by the light emitting element, depending on the amount and shape of the hair, the position of the top of the head may not be accurately detected, resulting in errors in the measured values. There was a fear that he might come.

(Means for solving the problem) This invention is an attempt to solve the problems seen in conventional height gauges, and is to sequentially insert and remove a plurality of length measuring rods 3 and 4 from the base length measuring rod 2. A cursor 1 is brought into contact with the head of the person to be measured on the tip fitting 12 fixed to the upper end of the length measuring section 1, which can be freely expanded and contracted over its entire length.
A heel fitting 1 having a claw 16 fixed to the heel 3 and a claw 16 provided below.
5 and provided with a socket for the AC adapter, insert the claw 16 into the hole 18 made in the step part 17, and attach the mounting bracket 14 to the step part 17 with a screw.
with the base point setting switch 9, hold button 10, and display window 6 facing upward, which are activated when the lower surface of the tip metal fitting 12 comes into contact with them, and the power switch 7.
It is characterized in that a display/operation unit 5 with an AC/DC changeover switch 8 and the like provided on the side is fixed to the tip of the base measuring rod 2.

(Function) The length measuring section is expanded and contracted by moving each length measuring rod in and out, and the cursor at the tip is brought into contact with the upper end of the head to detect the amount of expansion and contraction of the length measuring section and digitally display it on the display section. The length measuring section can be shortened by sequentially storing each length measuring rod, and can be easily separated from the step section by simply removing screws. Furthermore, since the engaging pawl formed at the bottom of the heel fitting is engaged with the lower surface of the step, the connection with the step is strong and there is no fear that the length measuring part will wobble.

Furthermore, when a chair or a weight scale is placed on the step stool, the correction associated with the height can be easily corrected by the length of the correction member.

(Effects of the invention) According to the digital display height meter of this invention, the length measuring section is composed of a plurality of length measuring rods that can be moved in and out, and the overall length is shortened when stored and can be separated from the step section. It can be made into a compact form, making it extremely convenient to transport and store, and since the cursor is placed in contact with the top of the subject's head to take measurements, it can be used depending on the amount and shape of the hair. There is no fear of measurement errors, and height can always be measured accurately.

Furthermore, height measurement becomes more convenient because corrections that occur when using a chair or scale can be easily made.

(Example) A preferred example of this invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a length measuring section, which includes a plurality of length measuring rods 2, 3, which can be freely moved in and out.
4, and can be shortened by sequentially storing other measuring rods 3 and 4 in the measuring rod 2 serving as the base, and can also be pulled out and extended to a desired length.

A display operation section 5 is disposed at the upper end of the base measuring rod 2. The display operation unit 5 has a display window 6 that digitally displays measured values, and further includes a power switch 7,
AC/DC changeover switch 8, reference point adjustment switch 9
A hold switch 10 is also provided. Further, a battery 11 is housed in the display/operation section 5 in a replaceable manner.

A tip fitting 12 is fixed to the upper end of the measuring rod 4 at the top end, and a plate-shaped cursor 13 is fixed to the tip fitting 12, and the height is measured by touching the cursor 13 to the upper end of the head of the person to be measured. do.

A mounting bracket 14 having a heel abutment plate 15 is attached to the lower part of the base length measuring rod 2, and a claw 16 formed at the lower end of the heel abutment plate 15 is inserted and locked into a hole 18 of a plate-shaped step part 17. The length measuring part 1 and the step part 17 are connected by screwing the mounting bracket 14 to the step part 17 with screws 19. The engagement between the claws 16 and the holes 18 allows accurate positioning during assembly and prevents the length measuring section 1 from falling. Further, since they are connected by screws 19, the length measuring section 1 and the step stool section 17 can be easily separated by unscrewing the screws 19, and the whole can be made compact for storage.

Reference numeral 20 is an AC adapter, which converts commercial AC power into DC and inputs it.

As mentioned above, the length measuring section 1 is composed of a plurality of length measuring rods 2, 3, and 4 that can be freely moved in and out.When each length measuring rod is paid out in sequence, the built-in length measuring tape is pulled out and the length measuring tape is By optically or electronically detecting and counting the length measuring points provided, the length of the length measuring rod being pulled out is measured, and the measured value is digitally displayed on the display window 6. For such a length measuring mechanism, for example, the mechanism disclosed in Japanese Utility Model Application Laid-open No. 62-73209 can be used.

Figure 5 shows the height with the measuring rod at its maximum length.
On the other hand, Figure 6 shows the shortest shortened state,
The maximum extended dimension is configured to be sufficiently longer than the height of a normal person, and the length measuring section can be made compact in the shortened state. In the illustrated embodiment, the shortest length is the dimension between the cursor 13 and the step part 17.
It is set at 0.883m and has a length of less than 1mg.

7 to 9 show the case where the sitting height is measured, and the chair 21 is placed on the step stool 17. In this case,
Since the distance from the top surface of the chair 21 to the cursor 13 is the standard dimension 0.883, a correction member 22 corresponding to the height H of the chair 21 is fixed to the bottom surface of the tip fitting 12, and the base point adjustment switch 9 is set at the bottom end of the correction member 22.
