Abstract
The M.P. Measuring Tape (MPMT) is the tool for measuring of the inside and the outside dimension. The MPMT is particularly useful instrument for measuring of the distances located between the surfaces. This tool is provided with the special arrangement, which allows to read the internal distance without using of any additional facilities or calculations. In addition the MPMT is facilitated with the arrangement for adjustment of the spring tension. This feature allows to recondition the spring, when the last one is getting weak.
Description
2.0 BACKGROUND OF THE INVENTION
2.1 Field of the invention This invention relates to the measuring tools used for measurement of any parts, bodies or spaces. The device is particularly useful, when the internal measurement is required.
The invention creates mufti purpose tool for measuring of the inside and outside dimensions based on the visual display of the measured distance.
2.2 Prior Art The existing devices for measurement, which are known as a Measuring Tapes (MT) comprise following components:
a) housing b) tape (steel blade) with printed scale c) spiral spring Majority of the MTs are provided with additional device like:
d) blade stopper (locking device) or blade release (unlocking device) e) belt clip The tape for measurement is mostly built from steel strip (blade). This blade is wrapped on the spool located inside of the MT Housing. Short tapes (up to 30 feet ) are provided with the spring, which retracts the blade.
_7_ The MT is used for measurement of any parts or spaces between the parts. The measured dimensions can be of two types:
a) outside dimension - O.D.
b) inside dimension - LD.
The O.D. is measured mainly as it shown on the Fig. I .
The LD. measurement required to use method shown on the Fig. 2. According to the sketch the final inside dimension (from 'A' to 'B') is actually buildup of two parameters. One is the distance covered by the tape and another by the MT Housing. Finally the LD. is the sum of the both of them (Housing size plus the Tape Length).
This method of LD. measurement required to know the size of the MT's housing.
For to make the task of the measurement convenient, almost every manufacturer provides on the MT's Housing the information about the housing's width. In most cases this dimension is written on the surface of the Housing in both systems (metric and imperial).
The described process of the LD. measurement can be simplified by using the attached invention.

3.2 Aim of the invention The aim of the invention is to create the tool for measuring of the inside dimensions by using most reliable and the simplest procedure.
3.3 The components of the M.P. Measuring Tape The M.P. Measuring Tape (MPMT) comprises the following components:
I ) Housing 2) Tilted Arm 3) Tape {with printed scale)
4) Spring
5) Spool
6) Stopper {locking device)
7) Gear-pin (spring adjuster)
8) Belt Clip
9) Insert-A
10) lnsert-B
The description of the MPMT's components is supported by the sketches No 3 to 3.4 The process of the 1.D. measuring The process of the measurement of an LD. dimensions based on the following procedure.
The MPMT device has to be located inside of the measured space (see Fig. 2).
The rear surface of the housing is attached to the point 'B' and the tape (the blade) is extended to reach point 'A'. At this stage the tape has to be locked at his extended position by turning the locking arm of the stopper to position 'LOCK'. The final measurement can be read in the barrel surface by tilting the Arm (part No 2) to his end position (see Fig. 8).
3.5 Description of the components 3.5.1 The Housing The Housing (part No 1 ) of the MPMT is designed to allow installation of all the parts and to maintain their proper functioning. The housing himself is built from two parts (top and bottom).
The Top Half is provided with the gear uses one way coupling to allow additional spring spiraling.
The Second Half is provided with the arrangement for location of the Gear-pin (part No 7) and fixing of the Belt Clip (see Fig. 6 Detail 'A').
3.5.2 The Tilting Arm The Tilting Arm (part No 2) is pivotally connected to the Housing (see sketch 3,4 and 5). The purpose of the Tilting Arm is to allow reading of the internal measurement.
3.5.3 The Tape The Tape (part No 3) is conventionally designed part with two types of the scale provided on the inner side of the blade.
a) metric scale (mm) b) imperial scale (inch) 3.5.4 The Spring The Spring (part No 4) uses as an accumulator of the energy, which is created during the pulling of the blade out. This energy is used to retract the Tape back into the Housing. The Spring is connected to the Housing through the Gear-pin (part No 7) and other end to the Tape.
3.5.5 Spool The Spool (part No 5) is provided with two spaces. Internal space uses as a room for spring.
Outside space is sized for the Tape. In order to prevent wrong spiraling of the spring, the spool is provided with the cover, which closing and locking the internal spring's room 3.5.6 Stopper The stopper (part No 6) is provided in order to catch the Tape in the required position (see Fig. 3 detail A~_ The Stopper is located at the head of the Tilting Arm. The locatian of the Stopper is such that during the process of locking the Tape's print is prevented from damage. The direction of turning the stopper to position of 'LOCK' helps to tight the Tape. This arrangement is necessary, when the reading of the internal measurement is required.
3.5.7 GEar-pin The Ger-pin (part No 7) uses spring holder and spiraling readjustment. The necessity for using of this device becomes important, when the spring's tension getting weak. The design of the pring tension adjustment based on the method of the non-return coupling (see Fig.
6). The non-symmetrical teeth of the coupling creating condition that the Gear-pin can rotate just one direction (the direction of increasing of the spring tension).
3.5.8 felt Clip The Belt Clip (part No 8) is a spring plate. The Belt Clip is bolted at the area of the Gear-pin extension (see Fig. 6 Detail A).
3.5.9 Insert A
The Insert A (part No 9) aimed to support the Tape at the printed surface (see Fig. 3). This is required during locking of the Tape by Stopper. The design of the Insert 'A' allows to maintain rigidity of the Tilting Arm (part No 2) under pressure of the stopper's tabs.
3.6.19 Insert B
The Insert B (part No 10) has two important functions a) To locate the Stopper into the Tilting Arm.
The Stopper is assembled into the Tilting Arm through the longitudinal opening. Finally after assembly of the Insert B this opening is blocked by the tab of the Insert. As result of that the shaft of the stopper can rotate in his final position without to drop out.
b~ To support the sha$ of the Stopper during locking the Tape.
During locking of the Tape, both tabs of the Stopper are under high pressure and they are intend to bend the Stopper's shaft. In order to prevent deflection of the Stopper's shaft the Insert is provided with two tabs, which are supporting the Stopper's shaft at his weak points.
