Description

[Detailed explanation of the invention] This invention is suitable for machining, woodworking, satsushi, architecture,
In the work process of civil engineering work, etc., requests for increases or decreases in numerical values for certain standard dimensions of parts, shapes, etc. can be easily made at the production or work site without going through the time and effort of making trial calculations using calculators and formulas. By devising the scale on the tape measure, etc.,
It is intended to be easily appropriated.

That is, in the past, for example, the horizontal dimensions of product part numbers A, B, C, and D shown in the production process chart were
Centering on a certain standard dimension W (for example, 230, the unit is mm, the same applies hereafter), A is +12 and B is +
35, C is -3 and D is -27, then the horizontal dimension of A is 262 by formulating 250 + 12, and similarly D is 223 of 250 - 27, and after each calculation, He was getting started on his work. however,
In a work process involving a large number of products, this calculation was extremely troublesome, and was not considered to be good in terms of work efficiency.

This invention solves the above-mentioned difficulties with an extremely simple device.

To explain this with the drawings, 1 is a tape measure and 2 is a slide finger measure. On the upper scale 3 and lower scale 4 of one side of the tape measure, scales are sequentially carved in mm units so that divisions such as 5 mm, 1 cm, 10 cm, etc. can be recognized. On the opposing upper and lower scales, the "0" indicating the beginning of the numerical value on the upper scale 3 is marked 10 cm from the tip of the tape measure 1, and the "0" point on the lower scale 4 is marked on the tip of the tape measure 1. It is 5.

The slide finger measure 2 is designed to sandwich the upper and lower scales 3 and 4 of the tape measure 1 and to be able to move smoothly in the lateral direction, and the upper surface 6 that covers the tape measure 1 is transparent or partially cut out. It is convenient for reading the numbers on the upper and lower scales 3 and 4 on the tape measure 1. Furthermore, the contact surface between one side (tip 5 side) of the upper surface 6 and the side surface is defined as a finger line 7, and in the lower surface 8 which is a flat surface,
The locking protrusion 9 is made to protrude downward at right angles at the end in contact with the side surface, and the line connecting the inner wall surface 10 of the locking protrusion 9 and the finger lines 7, 7 are made to coincide in cross section.

Now, if you attach the slide finger measure 2 to the tape measure 1 and take a dimension of +21 to W (150), then the tape measure 1
21 to the left (arrow) direction from the "0" point on the upper scale 3
, align the finger lines 7, 7 of the slide finger scale 2 with this scale, turn the set screw 11 that is the fastener,
Fix the slide finger measure 2 to the tape measure 1. Lock the locking protrusion 9 of the slide finger measure 2 to the tip of the member to be measured, read 150 on the upper scale 3 of the tape measure 1, mark the member, etc., and complete the measurement.

Also, for example, when taking a dimension of -37 for W (150), read 37 on the lower scale 4 of the tape measure 1, match the finger lines 7, 7 of the slide finger measure 2 there, and fix it with the set screw 11. . Next, the locking protrusion 9 of the slide finger measure 2 is locked to the tip of the member to be measured, the lower scale 4 of the tape measure 1 is read at 150, and at that point a mark is placed on the member, etc., and the process is completed. The locking protrusion 9 of the slide finger lever 2 catches the tip of the measuring member,
The scale on the tape measure 1 indicates the other end of the required dimension.

The fourth example shows how the tape measure 1 is housed in the case.
If the locking protrusion 9 is locked to the outer tip of the case as shown in the figure, it is convenient to draw it out, but the housing may be accommodated by any known means.

The present invention is particularly useful not only in mechanical work, but also in work sites such as sash, woodworking, architecture, and civil engineering.

Claims (1)

[Claims for Utility Model Registration] The upper scale 3 of the tape measure 1 is marked with a value starting from -100 mm, and the lower scale 4 is marked with a value starting from 0 mm, and the slide finger measure is attached to sandwich the tape measure 1. The upper surface 6 of the tape measure 1 is transparent or partially perforated, and the finger lines 7, 7 formed by the side surface near the tip 5 of the tape measure 1 are perpendicular to the horizontally long side line of the tape measure 1, and the flat surface is On the lower surface 8 of the sliding finger lever 2, a locking projection 9 is projected downward at a right angle from the side end in contact with the side surface, and the line on the inner wall surface 10 and the finger lines 7, 7 coincide in cross section. A sizing scale in which a slide finger measure 2, which is slidable on the surface of the tape measure 1, is attached to a fastener for fixing the slide finger measure 2 at a desired position on the tape measure 1.
