DETAILED DESCRIPTION OF THE EMBODIMENTS
As shown in FIGS. 1-4, a height measuring device of the invention comprises a scale 1, comprising graduation and a measuring part 2, and a positioning plate 6. The graduation and the measuring part 2 are disposed on a right side 5 of the scale, and the measuring part 2 is capable of moving along the graduation and indicating height.
A measuring plate 3 is disposed on the measuring part 2, and capable of folding as being perpendicular to or parallel to the scale 1.
A top edge 14 of the scale is capable of being buckled with a bottom edge 9 of the positioning plate, and a bottom edge 15 of the scale is capable of being buckled with a top edge 8 of the positioning plate.
A fixing part 13 is disposed at the backs 12 and 16 of each of the scale and the positioning plate 6, and capable of being disposed in a vertical plane. In this embodiment, the vertical plane is wall.
A pair of buckling parts 10 is disposed on a right side of the positioning plate 7, and the back 12 of the scale, and capable of being buckled with each other.
The scale 1 is divided into multiple sections, and a folding mechanism is disposed between two adjacent sections whereby facilitating folding of the sections. Alternatively, the sections are connected to each other in a manner of inserting.
Another folding mechanism is disposed at the center of the scale 1. In this embodiment, the folding mechanism is a leaflet 4. An upper part and a lower part of the scale 1 are capable of being folded via the folding mechanism, and the back 12 of the scale is folded inwards. As shown in FIG. 1, this greatly reduces a length the scale 1, and ensures that a measurement range thereof is not to be reduced for the purpose of transportation and storage.
As shown in FIG. 2, a pair of arc-shaped concave parts 11 is disposed on both sides of the center of the positioning plate 6. During installation, a user clamps the concave part 11 via his fingers, which makes the invention easy for use.
An upper part and a lower part of the positioning plate 6 are axially symmetric to each other.
As shown in FIGS. 5-8, a first method of using the height measuring device of the invention is illustrated.
As shown in FIG. 5, firstly the positioning plate 6 is disposed at the back 12 of the scale via the buckling part 10, and the bottom of the scale 1 abuts against the ground, and tightly leans against the wall in a direction perpendicular to the ground. Then, the positioning plate 6 is fixed on the wall via the fixing part 13 at the back of the positioning plate 6, and the scale 1 is separated from the positioning plate 6. In this embodiment, the fixing parts 13 disposed at the back of the scale 1 and the positioning plate 6 use a gumming, a sucker, or a screw to fix the scale 1 or the positioning plate 6 on the wall. After that, the bottom edge 15 of the scale is buckled with the top edge 8 of the positioning plate, and the fixing part 13 at the back 12 of the scale fixes the scale 1 on the wall.
As shown in FIG. 6, after the scale 1 is fixed on the wall, it is possible to fold the measuring plate so that it is perpendicular to the scale 1, and thus height measurement of children is implemented (as shown in FIGS. 7 and 8).
As shown in FIGS. 9-12, a second method of using the height measuring device of the invention is illustrated.
As shown in FIG. 9, the bottom of the scale 1 abuts against the ground, and tightly leans against the wall in a direction perpendicular to the ground. Meanwhile, the bottom edge 9 of the positioning plate is buckled with the top edge 14 of the scale. Then the fixing part 13 at the back of the positioning plate 6 fixes the positioning plate 6 on the wall.
After that, the bottom edge 15 of the scale is buckled with the top edge 8 of the positioning plate, and the fixing part 13 at the back 12 of the scale fixes the scale 1 on the wall.
As shown in FIG. 10, after the scale 1 is fixed on the wall, it is possible to fold the measuring plate so that it is perpendicular to the scale 1, and thus height measurement of children is implemented (as shown in FIGS. 11 and 12).
After installation, a maximum measurement length and a minimum measurement height using the first method are less than those using the second method, and users can select any of the methods according to heights of children. In addition, since measurement range of the two methods are different, graduation of the scale 1 can use a sticker with graduation, and a method corresponds to a measurement range of the sticker, and only needs adhering the corresponding the sticker to the scale 1.
To summarize, the invention features simple structure, and easy transportation and installation, and takes up small indoor space during use, and measurement results are very accurate.
Industrial applicability of the invention is: since most conventional height measuring devices are integrated with devices, such as weight balances and so on, and no height measuring device featuring convenient installation and usage is used, the invention is disposed on the wall, takes less indoor space, features convenient transportation and accurate measurement results, and is suitable for mass industrial production.
While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
