SK140495A3 - Measuring tape and tape meter with display representation of measured value - Google Patents

Abstract

Measuring band and band meter with display measured value and electronically recorded by varying the length gauge ejection circular cross-section. The value of length measures that is shown on the display corresponds to the sequence indicated a bar code that is the sum of the lengths on a moving carrier.

Description

MEASURING BAND AND METER WITH DISPLAY.

Technical field.

The invention relates to a measuring band and a tape measure with electronically recorded changes in the display of length measures.

BACKGROUND OF THE INVENTION.

The existing measuring bands and tape measures do not use the current possibilities of miniaturization and electronization. Usually, measuring bands and tape measures are used with steel, canvas or other length measures, which are recorded on the support with a numerical designation. Their drawback is the overall robustness and weight, which is determined by the capacity of the maximum lengths measured and the carrier material used.

Another drawback is their unreliability, resulting from their frequent use, which deletes the marking of length measures on the carrier, readability and, in particular, their total non-functioning in mechanical damage.

The requirement for electronically recorded changes in length measurements during measurement and their display on the light display is especially important for better orientation during measurement, higher accuracy, visibility, simplicity, diversity of use and environment, multiplication of maximum capacities of measured lengths, longer service life and overall x

climate comfort.

2. Summary of the Invention

SUMMARY OF THE INVENTION The present invention provides a measuring tape and a tape measure with a display of the measured quantity and electronically recorded changes in the display of length measures with a length measuring carrier of circular cross-section, characterized in that the length measures are indicated by a bar code. Functionality is conditioned by switching on the control integrated electronic circuit, microswitch.

Example

As an example of the realization of the invention of the measuring band and tape measure with display of the measured quantity, I present its implementation on a classical tape measure with a retractable carrier of length measures.

The values of the length measures are indicated by a bar code corresponding to the numerical sequence of the sum of the length measures on a movable circular cross-section carrier 10, the values indicated on which are measured by a bar code sensor 3 positioned at the outlet opening 12 of the measuring tape or tape measure 8 switching on the control integrated electronic circuit 7 with the microswitch 2.

Industrial usability

From the point of view of the manufacturers, the invention relates to the measuring, engineering, chemical and electrotechnical industry.

From the user's point of view, the invention can be used wherever conventional measuring bands and tape measures are used - generally. In a suitable embodiment, the invention can also be used on a crane rope, especially in those works where the crane does not see e.g. in mining, geological exploration and various wells.

When using the effect tkzv. Adrian's thread can be used in caves, mountaineering, diving and various other sports.

By adding the weight to the end stop of the measuring or tape measure, perpendicular, oblique or kinked profiles and hard to reach places can be measured effectively.

In case of possible mechanical damage (breakage of the length gauge carrier) it is possible to use the measuring band or tape measure further on, even in a smaller measuring range of the maximum length specified by the manufacturer.
