Technical Field

The invention relates to a tape measure having a housing and a pullout tape, wherein the pullout tape protrudes from a housing slot.

Background

In order to measure the size of an industrially manufactured product, for example, in quality control, it is necessary to individually measure the size automatically or manually. For quality control or for sample control, each individual product is subjected to precise, non-destructive measurements, and conclusions can be drawn from the characteristics of the measured values with respect to factors influencing the production by means of a large number of measured products. In the textile industry where hand-made is relatively large, it is important to check the exact dimensions of the textile produced, since a large number of manufacturing factors, which are not necessarily stable, can change the actual dimensions of mass-produced garments.

Disclosure of Invention

The object of the present invention is to propose a rolling ruler for use in quality control and/or sample control, by means of which a large number of measurements can be carried out reliably and simply for the user.

The object is achieved according to the invention by a tensioning and measuring device which can be removed from the housing, which in the removed state is arranged in front of the housing slot and serves as a tensioning and measuring device for the precise reading of the measuring graduation on the measuring tape. Further advantageous embodiments are given in the dependent claims of claim 1.

It is therefore provided according to the invention that the measuring tape has a tensioning and measuring device, for example in the form of a hook, wherein the tensioning and measuring device is part of the measuring tape and is not an additional element which can be separated from the measuring tape. The hook serves on the one hand as an auxiliary element for precisely placing the measuring tape against the measuring object. On the other hand, the hook may be used for tensioning a textile garment to be measured, such as a waist of a trousers, but may also be used for tensioning an opening of any other shape in a garment in order to ensure uniform measurement conditions when measuring a plurality of similar or identical garments, whereby the hook is used as an additional finger of a user.

In a first embodiment of the measuring tape, it is provided that the tensioning and measuring device is designed in the form of a hook and preferably has a straight reading edge. By means of a straight reading edge, a purely visual reading of the measured values by the human eye is facilitated.

For industrial use in quality control and in order to detect as many measured values as possible in a short time, it is advantageous if an electronic reading device for electronically reading the measuring graduation is present in the housing of the measuring tape, which electronic reading device transmits the measurement result to a remote receiver via a radio protocol by means of a request signal in the form of a button of a push switch.

In order to take into account the different states of the measuring tape, it can be provided that an electronic switch arranged in the housing detects the removal state of the removable tensioning and measuring device and forwards this removal state to an electronic reading device, which in this state subtracts a predetermined value from the measurement result in order to take into account the position of the removable tensioning and measuring device in the measurement result.

An electronic display device displaying the measurement results may also be present in the surface of the housing in order to check the measurements sent to the remote receiver.

In order to achieve sufficient stability for industrial applications, the tensioning and measuring device configured as a hook should be designed to be stable such that it can withstand tensile forces of up to 5kg (about 50N), in particular embodiments even 10kg (about 100N) and even more. This results in that the tensioning and measuring device cannot be torn apart.

In order to achieve a particularly ergonomic design of the measuring tape, it is provided that a thumb-operable button is provided for fastening the measuring tape in the measuring tape.

In a tape measure, the tape may have an optical code for electronic reading, wherein the optical code has an absolute dimension, i.e. the code at each position of the tape is configured such that the code at the respective position can read the absolute dimension of the tape, wherein, for example, the code may be selected from the group consisting of: optical metronome, measuring tool in vernier method by two measuring tools arranged side by side with different frequencies, bar code and incremental code, which can deduce the correct size by accompanying counting at the time of removal. Other optically machine-readable codes with absolute size codes are also conceivable. Therefore, the measuring standard cannot be configured to absolute dimensions. In this case, the detector counts the passes of the optical mark and counts the forward or backward passes of the optical mark, and thereby calculates the current size position. With an absolute code, it is easy for the user to calibrate the tape. For this reason, the user only needs one type of scale, which the user uses to measure. This can be done accordingly in order to pass the certification to this qualified official.

For uncomplicated use, it can be provided that the measuring tape has a contactless charging device in the form of an inductively coupled current transmission for the electronic reading device.

In order to control the execution of the measuring process, it is provided in a further embodiment of the invention that the electronic measuring tape has an electronic level.

Depending on the type of use, it can be advantageous if the tensioning and measuring device can be permanently locked in the extended state. In this case, the tensioning and measuring device can either be pulled out at the first use and then no longer be moved in by locking, or it can be permanently locked already at the time of manufacture. This locking is significant when the various measuring functions are to be reduced to one measuring function to simplify training work on the electronic tape.

Detailed Description

A tape measure 1 according to the present invention is shown in figure 1 in two adjacent views of the tape measure 1. The tape measure 1 has a housing 20 and a removable blade 30, wherein the removable blade 30 extends from a housing slot 40. According to the concept of the invention, it is provided that the tensioning and measuring device 50, which can be removed from the housing 20, changes from a removal position (left drawing) as indicated on the left by the first arrow to a removal position (right drawing) as indicated by the right arrow. The tensioning and measuring device 50 which can be removed from the housing 20 is arranged in the removed state (right drawing) in front of the housing slot 40 and serves here in a first mode of use as a tensioning and measuring device 50 for precise contact with a measuring point on the product to be measured. The tensioning and measuring device 50, which can be removed from the housing 20, by its shape helps to accurately abut and read the tape 30. In order to avoid the tensioning and measuring device 50 becoming jammed when not in use, when it is carried in a trouser pocket or when it is used in the textile sector, and possibly even damaging the material to be processed by the pulled-out thread, it can be provided that the tensioning and measuring device 50, which can be removed from the housing 20, can be moved in and out again.

In the embodiment shown here, the tape measure is implemented as an electronic tape measure. In addition to the already mentioned components, the electronic measuring tape 1 also has a display device 100 (display) on which the current measured value set on the tape 30 by the tensioning and measuring device 50 which can be removed from the housing 20 can be read. For electronic reading, an optical code 31 is printed on the back side of the tape 30, which is read by an optical sensor 33 within the tape measure 1 and forwarded to an electronic measuring device 34. The electronic measuring device interprets the optical coding 31, calculates a measured value therefrom and forwards the measured value to the display device 100 for displaying the measured value.

The measurement scale 60 on the front of the tape 30 is drawn on the left side of fig. 2, wherein it is also possible that no scale is desired and therefore not present that can be read by a person. Correspondingly, the measuring standard 35 or the bar code 36 present on the rear side of the measuring tape 30 is shown in the middle and on the right in fig. 2. The optical coding of the measuring tape 30 can be in the form of an optical metronome (Taktschrift), as a measuring standard 35 in the vernier method with two measuring standards arranged side by side at different frequencies (fig. 2, middle) or as a bar code 36 (fig. 2, right). Finally, the coding can also be designed sequentially, wherein the detector counts the passage of the coding and thus determines the dimensional position of the blade 30 by calculation.

In fig. 3, the tape measure 1 of fig. 1 is shown from below and has a housing 20 which is open on one half side. It can be seen from the half-side open housing how the tensioning and measuring device 50 which can be removed from the housing 20 is moved from the first position a into the second position b, wherein the two positions of the tensioning and measuring device 50 which can be removed from the housing 20 are shown in this diagram and thus overlap spatially. In the half-open housing 20 there is a thumb rocker 55 which is part of a thumb-operable tape brake 53 which secures the tape 30 being pulled from the housing 20 and locks the tape against the return force of a coil spring used to pull in the tape 30. However, the thumb stick 55 may also perform other, cumulative or alternative functions here, for example as an operating element for electronic navigation by means of a graphical operating system of the electronic reading device 80.

Fig. 4 shows a profile view of the housing 20 of the tape measure 1, into which the tensioning and measuring device 50, which can be removed from the housing 20, is inserted together with the tension spring 70. The tensioning and measuring device 50 which can be removed from the housing 20 can be moved from a first position a (in-moved state) into a second position b (out-moved state) and can be locked in these positions, but is at least fixed by a latching device. In the retracted state (fig. 4 top) of the tensioning and measuring device 50 which can be retracted out of the housing 20, the tension spring 70 is extended and tensioned, and in the extended state of the tensioning and measuring device 50 which can be retracted out of the housing 20, the tension spring 70 is less tensioned and shorter. The stroke of the tensioning and measuring device 50 which can be removed from the housing 20 is illustrated by the double arrow between the first position a and the second position b in the two figures, in the upper part of fig. 4 and in the lower part of fig. 4, wherein the tension spring 70 relaxes when the tensioning and measuring device 50 is removed. Different positions a and b result in different contact positions and contact edges, which are advantageous depending on the type of application. In the retracted state a, the reading edge 52 at the front edge of the tensioning and measuring device 50 can be used, wherein, for example, an automatic or manual switch (such as the operating buttons 81, 82 and 83) causes the electronic reading device 80 together with the display device 100 to be configured to display the size at the reading edge 52 in the retracted state a. It is also possible to use the reading edge 52 on the front edge of the tensioning and measuring device 50 in the extended state b, wherein an automatic or manual switch (e.g. operating buttons 81, 82 and 83) causes the electronic reading device 80 together with the display device 100 to be configured to display the size at the reading edge 52 in the extended state b. By means of manual switches, for example, operating buttons 81, 82 and 83, it is also possible to set the dimension of the trailing edge 52b on the trailing edge of tensioning and measuring device 50 in extended state b. By these same operation keys 81, 82 and 83 or by other switches, the electronic reading device 80 together with the display device 100 can also be configured to a size displayed at the rear portion 85 of the housing 20.

A rear perspective view of the tape measure 1 of figure 1 in a first typical application type is shown in figure 5. The back side view of the tape measure 1 shows a view of the keys operable with the fingers of the right hand. However, these keys can also be operated very well with the thumb of the left hand. These operating keys 81, 82, 83 for the electronic reading device 80 in the housing interior are freely configurable and can each be assigned 2 functions. In this first typical type of application, a tensioning and measuring device 50 removable from the housing 20 is used to apply the unwound tape 30 to the surface to be measured (the tape itself should not be tensioned with a hook). The dimensions of the tensioned tape 30 can be conveniently read using the tensioning and measuring device 50 which is removable from the housing 20. In this perspective view, it can also be seen how, in the extended state b, the dimension at the leading edge 52b on the trailing edge of the tensioning and measuring device 50 can be read.

Fig. 6 shows a view of an internal detail of a tape measure 1 according to the invention in which the front housing wall of the housing 20 is removed and the tension spring 70 is removed from the diagram of fig. 6. As shown in the upper sketch of fig. 6, inside the measuring tape 1 there is a reel 32 for the measuring tape 30, wherein the measuring tape 30 is guided between the reel 32 and the housing slot 40 through an optical sensor 33 which reads an optical code 31 printed on the back side of the measuring tape 30 and transmits it to an electronic reading device 80 which interprets the detected optical code and calculates the measured values therefrom. The electronic reading device 80 transmits the calculated measured value as a display value to the display device 100 (display), where it can be read by the user. By pressing a button, the calculated measured value can also be passed through the radio protocol (for example by) Is transmitted to a remote receiver where the determined and transmitted measurement values are included in statistics, e.g. for quality control. Provision is made for an electronic switch present in the housing 20 to detect the removable tensioning and measuring device50 and forwards it to the electronic reading device 80, which in this state subtracts a predetermined value from the measurement result in order to take into account the tension that can be removed and the position of the measuring device 50 in the measurement result. Depending on the application, the predetermined value can relate to the inner edge or the outer edge of the hook (inner and outer measurement). This can be selected and set in a menu. In the upper sketch of fig. 6, a thumb rocker 55 can be seen, which can be used on the one hand as a mechanical operating element of the tape brake 53 that can be actuated by the thumb, but also as a rocker for navigating in a graphical operating system that is output on a display device 100 (display). In the lower sketch of fig. 6, the reel 32 and the thumb rocker 55 are removed, so that a backside view of the interior of the operating buttons 81, 82, 83 can be seen.

Finally, a second typical type of application for the tape measure 1 is shown in figure 7. The waist of the trousers is tensioned by means of a tensioning and measuring device 50 configured as a hook, which can be removed from the housing 20. In measuring, the user holds the left portion of the waist of the pants with the left hand and the tape measure with the right hand, for example, so as to operate the tape measure by pressing the buttons. In this case, the measuring edge 52b is used as a reading edge. Since the right hand is now no longer free, the user can tighten the right portion of the waist with the hook as a substitute for another finger and thus measure the size of the waist for quality control or sample control. The left hand performs the measurements in correspondingly different ways. In this manner, a large number of waist measurements can be conveniently made, which are common to quality controllers in textile manufacturing. A common amount that a quality controller must measure per working day may be between 500 and 2000 textiles. For this type of application, it is provided that the tensioning and measuring device 50, which is designed as a hook 51, is designed in a stable manner such that it can withstand a tensile force of up to 5kg (approximately 50N) in order not to be damaged during a measurement of the hasty with possible rough handling under time pressure.

The embodiment of the tape measure shown has a "handedness". This is a right-handed design. The tape measure may also be configured in a left-handed design, mirror-inverted. This means that the tape measure shown here is optimised for use with the right hand, as shown in figure 7. According to a further concept of the invention, it is provided that the thumb-actuable button, the thumb rocker 55, the tape brake 53 and the further finger-actuable button 101 are arranged on the surface 21 of the housing 20 in an arrangement that is optimized for the right hand or alternatively for the left hand, in an ergonomic manner for determining the tape and/or for reading the measured values by the electronic reading device 80. For industrial use, in a further embodiment of the measuring tape, it is provided that the measuring tape has a contactless charging device 110 in the form of an inductively coupled current transmission for the electronic reading device 80.
