Description

[Detailed description of the invention] (Industrial application field) The present invention arranges a large number of rectangular plates in series, and connects each end of each plate so as to be rotatable. This relates to a folding scale with scales attached to the long sides.

(Prior Art) As a conventional art, there is a structure shown in FIG.

That is, a large number of rectangular plates 1, 2, 3, . , P2, P3... are rotatably connected, and the long sides of each plate material 1, 2, 3... are marked with a scale in mm or scale to indicate the length. Ta.

(Problems to be solved by the invention) In the above-mentioned conventional method, when each plate material 1, 2, 3... is folded, each plate material 1, 2, 3... is folded, as shown in FIG.
3... are overlapped in the thickness direction, and the folded shape is prismatic.

For this reason, the folding scale cannot be accommodated in a container with a small depth, such as a notebook or a pocket, and the storage area is restricted, resulting in a drawback that the scope of use is limited.

Furthermore, since the connecting parts of each plate material 1, 2, 3... were offset in the thickness direction, when measuring the flat part of the object to be measured, one of the connecting parts was connected to the flat part of the object to be measured. There was a drawback that the measurement of this part would be inaccurate as it would rise from the surface.

The object of the present invention is to obtain a novel folding scale that eliminates the above-mentioned drawbacks.

(Means for Solving the Problems) In order to achieve the above object, the present invention is constructed as follows.

That is, in a folding scale in which a large number of rectangular plates are arranged in series, their ends are rotatably connected to each other, and a scale is attached to the long side of each plate, Each plate has its wide side arranged in the same plane, and is connected at each end so as to be rotatable about the axis in the thickness direction.
The length of each plate is the length at which the outer circumferential edge of the center plate and the inner circumferential edge of the corresponding outer plate contact each other when the plate is wound spirally around one end of the plate. The configuration is set to .

(Function) Since the present invention has the above-mentioned configuration, the wide side of each plate member rotates on the same plane.

Then, when each plate is spirally wound around the plate at one end, the inner circumferential edge of the corresponding outer plate comes into contact with the outer circumferential edge of the center plate. The shape after the above winding becomes a rectangular shape.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In the drawings, Fig. 1 is a plan view of the embodiment of the present invention in an extended state, Fig. 2 is a sectional view thereof, Fig. 3 is a plan view of the folded state, and Fig. 4 is a sectional view of Fig. 3. It is a diagram.

In FIG. 1, 10 is a folding scale.

The folding scale 10 has rectangular shaped 9
It is formed by connecting plates 11 to 19 in series and rotatably.

The above-mentioned respective plate materials 11 to 19 have the same width W and thickness.

The lengths of every other plate material 13, 15, 17, 19 extending from the right end plate material 11 to the left are formed long and are set as follows.

That is, the length L ₃ of the plate 13 is the length L ₁ of the plate 11.
The value obtained by adding the width W of the plate material to the length L of the plate material 15 ₅
The length L ₇ of the plate 17 is the length L 1 of the plate 11 plus three times the width W, and the length L ₇ of the plate 17 is the length L ₁ of the plate 11 plus three times the width W. The length of each plate 19 is set to the same value as that of the plate 17.

In addition, the lengths of the plates 12, 14, 16, 18 located between the plates 13, 15, 17, 19 are as follows:
It is formed into a short length and set as follows.

That is, the length of the plate 12 is set to twice the width W, the length of the plate 14 is set to three times the width W, and the length of the plate 16 is set to four times the width W. Board material 18
The lengths of are set to five times the width W above.

The plates 11 to 19 are arranged as shown in FIG. 1 and rotatably connected to each other by pins P.

That is, the opposite short sides of the plates 11 and 13 are brought into contact with each other, and the plate 1 is placed in the abutting portion between the two.
2 and pins P and P at both ends of this plate material 12.
Connect by. In addition, the opposite short sides of the plates 13 and 15 are made to face each other with an interval of the width W of the plates, and each end of the plate 14 is overlapped with the facing portion of the plates 13 and 15. , P. In addition, the opposite short sides of the plates 15 and 17 are made to face each other with an interval twice the width W of the plates, and each end of the plate 16 is overlapped with the facing portion of the two, and both ends of the plate 16 are overlapped. and connect with pins P and P. In addition, the opposite short sides of the plates 17 and 19 are made to face each other with an interval of three times the width W of the plates, and each end of the plate 18 is overlapped with the facing portion of the two, and both ends of the plate 18 are overlapped. Pin P, P
Connect by. As a result, in this example, the total length is 1
m.

The structure of each of the above-mentioned connecting parts is shown in FIG.

That is, as shown in FIG.
The joint parts 11a, 1 are cut out in the lower half of the facing part.
3a, and the thickness of the plate material 12 is adjusted to the above-mentioned joint portions 1.
Both joint parts 11 are made equal to the thickness of 1a and 13a.
a, 13a, and these overlapping parts are connected by pins P, P.

In addition, each of the remaining connecting parts is formed by cutting out the lower half of one adjacent end and the upper half of the other end in a stepped manner to form joint parts 21 and 22, and each of these joints 2
1 and 22 are overlapped in the thickness direction on the notch side,
Connected by pin P.

In addition, the joining side end portions of each of the plate materials 11 to 19 are connected to the first
As shown in the figure, one half in the width direction is cut out in an arc shape to form relief parts 23, 23, etc., so that each of the plates 11 to 19 is aligned in one direction as shown in FIG. Make it bendable.

Then, on the long side of each of the plate materials 11 to 19, a scale in mm is written to indicate the length.

In addition, grooves 13b and 15a are formed on the long sides of the plates 13 and 15 on the opposite bending sides, and protrusions that can fit into the grooves 13b and 15a are formed on the long sides of the plates 17 and 19 on the bent sides. 17a and 19a are formed.

Next, the operation mode of the above embodiment will be explained.

Each of the plate materials 11 to 19 is formed to have the same thickness, and each joint part is formed thin and overlapped, and the overlapped part is connected by a pin P extending in the thickness direction, so that
Each of the plates 11 to 19 is on the same plane, and the direction of rotation thereof is on the same plane.

Therefore, when measuring the flat surface of the object to be measured, each of the plates 11 to 19 comes into close contact with the plan view of the object to be measured, allowing accurate measurement.

When each of the plates 11 to 19 is spirally wound around the plate 11 at one end, as shown in FIG.
The long sides of the plates 11, 13, 15, 17, and 19 are brought into contact with the short sides of the plates 11, 13, 15, 17, and 19 in order, and the long sides of the plates 12, 14, 16, and 18 on the short side are brought into contact with each other in order, and the winding is completed. After supination, the shape becomes thin and rectangular.

As shown in FIG. 4, the structure of the connecting portion of each of the plate materials 11 to 19 is such that the upper and lower surfaces of one end are cut out in steps to form a male joint portion 24, and the thick center portion of the other end is cut out in steps. The female joint part 25 may be formed by cutting out a groove shape, and the two may be rotatably connected by a pin P.

(Effects of the invention) As is clear from the above explanation, according to the invention, it is possible to easily store the object in a container having a small depth and a predetermined area, such as a notebook or pocket, and This has advantages such as being able to accurately measure the area.
