Abstract

PURPOSE:To obtain a measuring pole, which has a simple internal structure and is easy to handle, by constituting a plurality of pipes so that they can be freely expanded and contracted like a telescope, and providing a position, at which a height is read, at the top end of the outside pipe. CONSTITUTION:The measuring pole M is constituted by a plurality of pipes I 1, II1...n so that they can be freely expanded and contracted like a telescope. In this pole M, a position, at which the height from a reference surface N is read, is provided at an upper end (a) of an outside pipe (n). The numerical value of a scale at an uppermost end of the pipe I 1, which is extended to become the highest stage, is made to be the length of the pipe (n) having the reading upper end (a). Namely, the scale of the highest end (b) is made to be 12, which shows 12 decameters of the length of the pipe (n) having the upper end (a) (the height of the eye of an observer having an average stature is made to be 120cm and the numerical value of the scale is made simple). The numerical values are sequentially increased from 12 to 13, 14... in the downward directions as the length increased on the scale. Free stop devices (d), (e) and (f) are provided at the ends of the pipes I 1, II1..., other than the pipe (n) having the reading end (a).

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a foury stop type major ball.

It is used as a tape measure to measure the roughness of a high object (1) You cannot measure the height of the object unless you climb to the top of the object (2). If you use k (ψ), in order to align one end of the tape measure with the top, you have to go up to the flat point. Even if you use the foot measurement method, where you first place one end of the tape measure at the bottom of the object to be measured, you have to lower your head down to the bottom of the object to read it. I have to go up.

Therefore, we made multiple tubes telescopically telescopic and retractable, hooked the extended tips to the top of the object to be measured, and read the height by looking at the scale on the built-in tape through the perforation of the tube at hand. Telescoping free-stop measuring balls are also available, but they have a complicated internal structure and are therefore heavy.
It had the disadvantage of being difficult to handle due to its sieve value. Is this invention a free-stop type mayor pole that can eliminate the drawbacks of soft soil?
Its purpose is to provide.

To explain the concept of the free-stop type major ball according to the present invention in terms of the main aspects shown in No./A and B, the concept of the free stop type major ball according to the present invention can be explained by using a plurality of 1, for example, 3. A measuring ball M is made of tubes 1 and 1.1 of the same length, for example, 5 pieces (6I11, used temporarily to express the eye position 11i of the foot in a simple numerical value), which can be expanded and contracted like a telescope. Thinking about f#3, the position of the object to be measured from the reference plane N, which is the position of the proboscis A, is the position V where H can be read.
Outer tube - Set the upper edge (A) as 7, and mark the length of the tube ■ on the outer periphery, and mark the numbers O and 12 on the scale of the upper edge (A), for example /,
23, for example, jlll12 on the scale, and the number on the scale on the uppermost edge (b) of the tube I, which is the topmost stage by extending the measuring ball M, is the number of the long J [of the tube.

That is, enter scale numbers such as j, (7, 7, 7, f---/3°/φ, /j so that the length increases from tube 1 to tube I. Note that the upper end of tube I A provisional measuring object hook is provided at one of the temporary measurement object hooks.

So, to explain how to use this measuring ball M to measure the sum H/ (this object is translated into 73) of the object A' shown in the /] bacterium (ha), first, Extend I and U to the maximum PJi, place the hook part of tube I on the top of object A, and immerse the lower end of tube 1 into the inside of the back.
Stand the bottom of the tube layer on the reference plane N, and read the number on the scale of the tube ■ that is bored at the upper edge (A) of the tube ■, which is the daytime reading position. 73 clothes are obtained.

The principle of this is as shown in Figure 2 (a).
As a circle, the higher H is the container a and b.

If cf is the fully expanded height, the height is /J-IN as shown in the second clause (i). Even if the arrangement of the pipes is changed and connected to pipes b, c, and a from above as shown in Figure 2 (b), this drawing /j suction will not have a long /lff
is small (not only does 7 not change, but in the 2nd M(i), the reading of /j suction cannot be determined unless the eye position is lowered at the reference plane N!, rm, 2m < ro) If you make a scale like this, the pot size /3R can be read on the line where the upper edge (a) of tube a, which is now at the bottom, is located. This means that the length of the canal a in Figure 2 (b) is the average inner eye daylight of the person standing, rl
For example, if it is kept hidden, the person who defines it can stand upright (in a comfortable position) and look at the cylindrical shape of the object to be measured.

However, in the case of the container pipe arrangement as shown in Fig. 2 (RO), it is inappropriate to have a configuration in which the container pipe is expanded and contracted. ) Nifu・Ke−
As shown in Figure 7 (Ro), the tube A below the incense is the largest diameter tube.
The tube layer entering the tube in FIG. 7 (ro) is
! If the top tube in the figure (ro) is the tube 1 that goes into the back volume, then the measure ball M shown in m/l1Q (ro)
Therefore,

However, with the structure shown in Figure 7 (b), when the major ball M is held upright, pipe 1 is relegated to the pipe exchanger, and official U is relegated to the pipe E7. , the container must be secured at any extended position with a free-stop device, as shown in Figure 31. In the tube l
There is no other choice but to install it in the part where the 11 is immersed in the kanden and the 11 is immersed in the 7. As shown in Figure 3 (b), the free stop device between the brass pipe 1 and the g-ho is (2), and the free stop device between the planting and the pipe (2) is (the river). As shown in Figure 1, there is a part of the container tube 1.1 that must be recessed into another tube, and that part does not fit into the scale when it is extended, so the container tubes are said to be of the same length. If the hook part e→ of the tube is brought into contact with the upper edge (a) of 'tQI (7) to make the whole container easier to carry, the length of the container can be reduced as shown in Figure 3 (a). There is no other way than a rock.

Therefore, the present invention is concerned. The structure of one embodiment of the free stop type measuring ball M will be explained based on the tI-th 1. In the measuring ball M which is configured to be telescopically telescopic and retractable with a plurality of tubes 11111--n, The position to read the height of the reference plane N. , the upper edge for front reading (A) is the length of the tube n to be sealed, that is, the scale of the uppermost edge (B), and the length of the tube n with the upper edge (A) is 7.2 mm. Power meter (eye position # of the person measuring the average height /20t7r
, and (7, to simplify the numbers on the scale) 7.2 and [
2. Starting from this 72, move 111 times downward to 73. /G,
/j --- The numbers are scaled in the direction of increasing length, and the tubes other than tube n which have the upper edge (a) for reading the MiT layout 1. ．． ), (e), and (e) are provided at each end of jl, --- on a free stop surface.

The free stop device can be thought of as something divine, but in this example, as shown in Figure 5 (b), it is
For example, at the upper end of the tube (■) for tube 1, there is a constricted part (g) that matches the outer diameter of the front blue (for example, the tube for tube 1).
, and a step (A) is formed near the upper end of the back.
As shown in 1iJld, there is a gap Q→ with respect to the inner wall (nu) of the tube, and the disc-shaped body (1i is partially cut out). At the notch part (force ti, the notch part second), there is a part plate (7 at the tip of the lake) with a beak piece (wa) that can be used by one person protruding from the disk-shaped body (su). There are 9 pieces, each consisting of a group (ArIIp) placed in a slotted hole.

Therefore, when tube O is rotated in the direction of arrow X relative to tW A, the spring plate (the effect is also
Although the beak 7 does not move, it fits into the beak (the tip of the ■ is in the gap), and the drafting action shields the inside of the tube and the tube A. This anchoring action causes the blue color to appear inside the tube. It can be inserted at any depth.

Since this embodiment has the configuration as shown in the paper, the tubes t, , a, ---1 other than the outer side tube n are completely extended, and the hook part (c) of the uppermost tube I is attached to the top of all the objects to be measured. The height of the object to be measured can be read by hooking the dovetail tube n to the reference surface NK and standing it upright with the tube n at the lower end touching the reference surface NK.

In addition, in this embodiment, the length ζ of the tube n can be read at the upper edge (A) of the average eyelid of the measurer in a standing position. Make the small stem shorter than the width of the average eye, and lengthen it by 7 steps so that the first stem becomes the average eye width (if it is 7 steps, the length of the two bottom stems) Of course, this is the number on the top scale of the top tube.

This invention has the structure and function as shown on paper7, and the measuring ball can be reduced in size, making it convenient to carry, and the measuring ball can be measured at the position Yt of the platform on which the measurer stands. Part of this is that the measurement posture is extremely comfortable, and when the tube is contracted, there is a scale starting from 0 on the tube n on the outside.
You can freely measure the height of the object to be measured, which is one step lower than a normal straight scale.
