The invention will be better understood on reading the description which follows, with reference to the appended drawings, in which:

- Figures 1 and 3 are schematic top views of the measuring tool according to an embodiment of the invention in different positions of its movable spout,

FIG. 2 is a schematic view of an example of a plan on which the measurement tool according to the invention can be used,

FIG. 4 is a modular block diagram of the measurement tool according to an embodiment of the invention,

FIGS. 5 to 8 are schematic top views of the measurement tool according to an embodiment of the invention during different possible stages of its use,

FIG. 9 is a diagram of an example of a sensor that can be used in the measurement tool according to an embodiment of the invention,

- Figures 10 to 12 are schematic top views of an odds measurement machine on a virtual document, according to an embodiment of the invention during different possible stages of its use.

In FIGS. 1, 3 and 5 to 8, the measuring tool 1 comprises a first spout 3 fixed to a support 2 and a second spout 4 which can be moved manually on the support 2. The first spout 3 has a first end 31 for application against a plane P, while the second spout 4 has a second end 41 of application against the plane P. The displacement of the spout 4 on the support 2 makes it possible to vary the actual distance between the first end 31 of application and the second end 41 of application. For example, the spout 4 is guided on the support 2 along a guide direction 21, to vary the distance between the ends 31 and 41 along this guide direction 21. Of course, the invention is applicable to any other type of movement of the spout 4 relative to the spout 3.

The ends 31 and 41 can be applied against a document, physical or virtual, such as for example a plane P, which can in particular be a plan of a construction, as indicated above, and which can include drawings DES of a building or the like, as shown by way of example in FIG. 2. The plane P is dimensioned, that is to say that it has dimensions indicating lengths present between marks, for example the marks R1, R2, R3, R4, forming part of the plane P in the DES drawing. The document or plan P can also be virtual, in that it is displayed on a screen E of a machine T, as shown in FIGS. 10 to 12. In the following, the term plan can be replaced by document generally.

In FIGS. 1, 3 and 5 to 8, the support 2 may or may not include a graduated rule 22 on which the second spout 4 is movable so as to be able to read visually opposite which graduations 23 of the rule 22 is the second end 41 of the second spout 4. The first end 31 and the first spout 3 may for example be located opposite a zero scale of the rule 22.

The nozzles 3 and 4 can be of the internal nozzle type as shown in the figures, that is to say that the two ends 31 and 41 of application of these are opposite one another and delimit between them a free space. However, the spouts 3 and 4 could also be of the exterior spout type, that is to say that the ends 31 and 41 are turned towards the outside by the distance separating them. Alternatively, one of the spouts 3 and 4 can be of the inner spout type and the other of the spouts 3 and 4 can be of the outer spout type. The application end 31 and / or 41 may be in the form of a point.

In the embodiment of FIGS. 10 to 12, the spouts 3 and 4 and ends 31, 41 can be replaced by a first virtual point 31 and a second virtual point 41, which can be displayed and moved on the screen E on the document P. The spouts 3, 4, ends 31, 41 and virtual points 31, 41 are generally designated by first point 31 and second point 41, which can be physical or virtual.

ίο

The measurement tool 1 is first described below with reference to FIGS. 1 to 9. Of course, what is described below for the measurement tool 1 is also valid for the machine T of FIGS. 10 to 12.

The measurement tool 1 also comprises at least one sensor 5 or 56 capable of providing a quantity D for measuring the real distance between the first application end 31 or first point 31 and the second application end 41 or second point 41. The measurement tool 1 also comprises at least one display unit 6 making it possible to display at least one dimension L of plan and which can be formed for example by a display with digital segments (as shown in FIGS. 1 , 3, 5 to 8) or a display screen. The dimension L of the plane displayed by the unit 6 varies, for example in a monotonic manner, as a function at least of the measurement variable D supplied by the sensor 5. For example, in the position represented in FIG. 1 of the spout 4, the display unit 6 displays a plane dimension L0 of 60 mm, for a plane scale of 1: 1.

In the example of Figure 3, the spout 4 is against the spout 3 and the ends 31 and 41 are against each other, so that the distance between them is zero and that the plan dimension displayed by the display unit 6 is 0.0 mm for a plane scale equal to 1: 1.

Of course, the spout 4 and its end 41 can for example take any position between a minimum spacing and a maximum spacing, in a continuous or discreet manner, on the support 2, as indicated by the two arrows shown in the figure. 1.

According to the invention, the measurement tool 1 or the machine T comprises a man-machine interface 7 comprising a numeric keypad 71. This numeric keypad 71 comprises keys or buttons, for example ten keys for the numbers 0, 1, 2 , 3, 4, 5, 6, 7, 8 and 9, a key 71a for a numeric comma and a key 71b for deleting the entry. The numeric keypad 71 allows numeric values to be entered. The keypad 71 allows the user to enter at least a first corrective dimension L1 and / or at least a second scale value SC.

In addition, the man-machine interface 7 comprises at least one key (72 or 73 described below) making it possible to cause the recording in a memory 9 of a multiplicative factor FCL for correction of the dimensions.

According to a first embodiment of the measuring tool 1 and of the measuring method according to the invention, the man-machine interface 7 comprises a first key 72 or the like (as indicated below) making it possible to record in memory 9 a first corrective dimension L1, which has been entered by the user on the numeric keypad 71. Pressing the first key 72 makes it possible to store in memory 9, with this first corrective dimension L1 the magnitude of distance measurement D1 (called first distance D1 of spouts) supplied by the sensor 5 and corresponding to a position of the second spout 41 on the support 2, having been chosen by the user.

Thus, for example, to carry out a measurement process using the measurement tool 1, the user, during a first calibration step, moves the second spout 4 to this first position chosen relative to to the first nozzle 3 and applies their first and second ends 31, 41 of application being in this first position against the first marks of the plane P, for example the first marks R1 and R2 of the plane P as shown in FIG. 5.

Then, in FIG. 6, the user enters on the numeric keypad 71 the first corrective dimension L1 (as represented by the arrow F1) and actuates the first key 72 (as represented by the arrow F2).

The measurement tool 1 also includes a computer 8 programmed to calculate and store in memory 9 the multiplicative factor FCL for the dimensions. The computer 8 calculates the multiplicative factor FCL of correction equal to the first corrective dimension L1, having been recorded in memory 9, divided by the first distance D1 of beaks, having been recorded in memory 9 in association with the first corrective dimension L1 having been recorded in memory 9, that is to say that FCL = L1 / D1.

Indeed, even having been able to enter before the step of FIG. 6 the nominal scale indicated on the plane P (for example 1:20 in FIG. 2) by the second key 73, the dimension displayed by the unit 6 in FIG. 5 (for example 6000 mm) may differ from the dimension C1 (for example 590 cm in FIG. 2) indicated on the plane P and separating the marks R1 and R2 from the plane P, due to uncontrolled dimensional deformations of the plan, due to its photocopying by a printer or its printing on a printer or its digitization by a scanner. The first key 72 makes it possible to correct this dimension L0 in the first corrective dimension L1, which will be equal in the example of FIGS. 2 and 6 to 5900 mm to be equal to the dimension C1 of 590 cm indicated on the plan P. The first key 72 therefore makes it possible to return to FIG. 6 a corrected scale value equal to this multiplicative factor FCL of correction in the memory 9, to take account of the dimensional deformations of the plane P relative to the scale which it indicates.

When the user wishes to measure any dimension L2 delimited by marks on the plane, such as for example another dimension C2 delimited by marks R1 and R3 and the value of which is indicated on the plane P, and / or another dimension C3 delimited by the marks R3 and R4 and whose nominal value is not indicated on the plane P, the user moves the second spout 5 on the support 2 to a second chosen position, different from the first position or identical to the first position , relative to the first nozzle 3, and applies the first and second ends 31, 41 of application being in this second position against the second pins of the plane delimiting this second dimension (R1, R3 or R3, R4 in the examples below) above).

The computer 8 is programmed to calculate the second dimension L2 of the plane corresponding to the second position chosen. The second dimension L2 of the calculated plane is corrected by the measurement quantity D supplied by the sensor 5, multiplied by the multiplicative factor FCL of correction. Thus, the second dimension L2 of the calculated plane is equal to a constant near B to the measurement quantity D supplied by the sensor 5, multiplied by the multiplicative factor FCL of correction, that is to say that L2 = D. FCL + B, the constant B being determined and being able to be null or not null and being able to be the opposite of a reference dimension compared to which the other dimensions are measured.

According to one embodiment, the second dimension L2 of the calculated plane is equal to the measurement quantity D supplied by the sensor 5, multiplied by the multiplicative factor FCL of correction, that is to say that L2 = D. FCL, which corresponds to the constant B equal to zero in the above.

The computer 8 then controls the display unit 6 to send it the second plane dimension L2 and cause it to display this second plane dimension L2 corresponding to the second position chosen.

The first key 72 thus makes it possible to calculate the real scale SC of the plan (for example 1: 19.67 in FIG. 6), which is different from the nominal scale indicated on the plan (for example 1:20 in FIG. 2) due to the dimensional deformations of the plane. This corrected real scale (or multiplication factor FCL of correction) is memorized and is used to display all the dimensions of the plane P by displacement of the second nozzle 4.

In a second embodiment of the measurement tool 1 and of the measurement method according to the invention, the man-machine interface 7 comprises a second key 73, the actuation of which by the user causes the recording in the memory 9 of a second scale value SC, which has been entered by the user on the numeric keypad 71 during a first calibration step. For example, the user can enter the nominal scale of plane P as the second scale value SC.

Even having previously entered the nominal scale indicated on the plane P (for example 1:20 in FIG. 2) by the second key 73 and when the user positions the nozzles 3 and 4 against the marks R1 and R2 of the plan, the dimension L0 displayed by the unit 6 (for example 6000 mm in figure 5) can differ from the nominal dimension C1 (for example 590 cm in figure 2) indicated on the plan P and separating the marks R1 and R2 of plane P, due to uncontrolled dimensional deformations of the plane, due to its photocopying by a printer or its printing on a printer or its digitization by a scanner.

This second embodiment may provide that the user enters, during the first calibration step, on the numeric keypad 71 as the second scale value SC, not the nominal scale indicated on the plane P (for example 1:20 in figure 2), but a corrected scale value SC (for example 19.67 in figure 8). The user may have previously calculated this second scale value SC different from the nominal scale indicated on the plane P, by himself calculating this second scale value SC (for example 19.67) as being equal to a dimension indicated on the plane P (for example the dimension C1 equal to 590 cm between the marks R1 and R2) divided by the real distance D1 (300 mm in figure 5) on the plane P between the two marks R1 and R2, which can be measured for example in FIG. 7 using the measurement tool 1 in which an initial SCO scale value equal to one has been recorded by the second key 73 (the second scale value SC being set by default at value one). The second scale value SC, having been entered by the user on the numeric keypad 71, is recorded by the computer 8 in the memory 9.

The computer 8 and the measurement tool 1 are programmed to calculate the multiplication factor FCL of correction equal to the second scale value SC recorded in memory 9, that is to say FCL = SC. The computer 8 stores the multiplication factor FCL of correction in the memory 9.

Then, during a second step of measuring any dimension L3 of any plane, the user moves the second spout 4 on the support 2 to a position which is chosen relative to the first spout and applies the ends 31 and 41 of application being in this position chosen against marks of the plane P, whose dimension L3 separating these marks is to be measured (for example the dimension L3 delimited by the marks R3 and R4 on the plane P in Figure 2, whose nominal value is not indicated on the plan P).

The computer 8 is programmed to calculate the dimension L3 of the plane corresponding to this chosen position. The calculated plane dimension L3 is corrected by the measurement quantity D supplied by the sensor 5 in the chosen position, multiplied by the correction factor FCL recorded in the memory 9.

Thus, the dimension L3 of the calculated plane is equal to a constant near B to the measurement quantity D supplied by the sensor 5, multiplied by the multiplicative factor FCL of correction, that is to say that L3 = D. FCL + B or L3 = D. SC + B, the constant B being determined and being able to be null or not null and being able to be the opposite of a reference dimension compared to which the other dimensions are measured.

According to one embodiment, the dimension L3 of the calculated plane is equal to the measurement quantity D supplied by the sensor 5, multiplied by the multiplicative factor FCL of correction, that is to say that L3 = D. FCL or L3 = D. SC, which corresponds to the constant B equal to zero in the above.

The computer 8 then controls the display unit 6 to send it the calculated plan dimension L3 and make it display this plan dimension L3 corresponding to the second position chosen.

The second key 73 thus makes it possible to correct the scale of the plane P into a real scale SC making it possible to go directly from the distance measurement D1 of the sensor to the real dimension delimited by markers of the plane. The second key 73 therefore makes it possible to enter a corrected scale value equal to the multiplicative factor FCL of correction in the memory 9, to take account of the dimensional deformations of the plane P relative to the nominal scale which it indicates.

The display unit 6 may comprise a first display area 61 displaying the dimension L0, L1, L3 of the plane, having been calculated by the computer 8, and a second display area 62 displaying the multiplication factor FCL of correction , having been saved in memory 9.

In the embodiments shown in the figures, the display unit 6 is fixed to the first spout 3 or to the support 2. However, in other embodiments not shown, the display unit 6 can be fixed to the second movable spout 4. Similarly, in the embodiments shown in the figures, the man-machine interface 7 is fixed to the first spout 3 or to the support 2. In other embodiments not shown, the man-machine interface 7 and / or the display unit 6 and / or the computer 8 is deported to a remote telecommunications terminal. This telecommunications terminal can be for example a mobile phone, a watch, a tablet or a laptop or the like.

For example, the man-machine interface 7 is included in the communication terminal, which is itself remote from a distance measurement unit in which the support 2, the first spout 3, the second spout 4, the sensor 5, the display unit 6 and the computer 8 are located.

In another example, the display unit 6 is included in the communication terminal, which is itself distant from a distance measurement unit in which the support 2, the first spout 3, the second spout 4, the sensor 5, the man-machine interface 7 and the computer 8 are located.

In another example, the computer 8 is included in the communication terminal, which is itself remote from a distance measurement unit in which the support 2, the first spout 3, the second spout 4, the sensor 5, the display unit 6 and the man-machine interface 7 are located.

The distance measurement unit and the communication terminal are provided with communication means enabling them to communicate with each other by a wireless telecommunication link.

The sensor 5 can be resistive or other.

According to one embodiment, in the case of a resistive sensor, the magnitude D of measurement supplied by the sensor 5 can be for example an electrical voltage or an electrical resistance, which varies monotonically as a function of the real distance D between ends 31 and 41.

For example, in the case of a resistive sensor 5, in FIG. 9, this sensor 5 comprises:

a first conductor 51 extending from its first end 511 situated on the side of the first fixed spout 3 along the direction 21 of guide on the support 2 to its second free end 512,

- a second conductor 52, extending from its third end 521 situated on the side of the first fixed spout 3 along the direction 21 of guide on the support 2 to its fourth free end 522,

- A third transverse conductor 53 extending in a second direction 24 intersecting with respect to the first guide direction 21 and for example perpendicular to this direction 21 of guide.

The third transverse conductor is fixed to the second movable spout 4 below this so as to be in contact with the two first and second conductors extending on the support 2. The electrical resistance seen by the first end 511 of the first conductor 51 and the third end 521 of the second conductor 52, varies as a function of the position of the second nozzle 4 movable along the guide direction 21, because the third transverse conductor 53 short-circuits the first and second conductors 51, 52 of the support 2 in this position. This resistive type sensor 5 may include a constant current source 54 connecting the first end 511 of the first conductor 51 to the third end 521 of the second conductor 52 and to a device 55 for measuring voltage or electrical resistance between these two ends 511 and 521 of the conductors 51, 52, the displacement of the second spout 4 on the support 2 in the direction of guidance 21 in this case varying the electric voltage or the electrical resistance between these two ends 511 and 521 of the conductors 51, 52.

According to one embodiment, in FIG. 4, the human machine interface 7 may further comprise a third key 74 to cause the reset of the dimension L of the plane for a certain other position of the second spout 4 on the support 2, having been chosen by the user. This other position for resetting the plane dimension L to zero can correspond, for example, to a measurement quantity D of a real zero distance between the first end 31 of application and the second end 41 of application of the nozzles 3 and 4. , as shown in FIG. 3, or at another position where the measurement quantity D corresponds to a non-zero real distance between these ends 31 and 41. The calculation of the plan dimensions L by the computer 8 will then be done by subtracting of the measurement quantity D of distance supplied by the sensor 5, multiplied by the multiplication factor FCL of correction, the reference LREF dimension calculated in said other reset position of the second nozzle 4, when the user has pressed the third reset key 74 (which can be in the above the constant B = - LREF).

The man-machine interface 7 can comprise a fourth key 75 causing the conversion of the dimension L of the plane into a length measurement unit which can be selected from several measurement units of different lengths prerecorded in the memory 9, for example in millimeters, centimeters, meters or inches, feet, or others.

The man-machine interface 7 may include a fifth key 76 causing the second scale value SC (SC = 1) to be set to value one, as for example in FIG. 5. By default, that is to say saying in the absence of actuation of the second key 73 by the user and in the absence of actuation of the first key 72 by the user, the second scale value SC remains at the value one. For example, any entry on the numeric keypad 71, which is not stored in memory 9 within a certain time (for example five seconds or other) by pressing the button 72 or 73, is replaced by the actual value of the quantity D distance measurement before entry, i.e. by a dimension L displayed equal to a value calculated for the second scale value SC equal to one (in this case L = D).

The measuring tool 1 may include a device for retaining the spout 4 movable on the support 2 in each position chosen by the user, in order to maintain the movable spout 4 in this position on the support 2 below a certain threshold. displacement force exerted on the movable spout 4. This makes it possible to apply the nozzles 3 and 4 to markers of the plane P without these nozzles moving relative to one another. Thus, the user must exert a displacement force greater than this retaining force threshold, to again move the spout 4 relative to the first spout 3.

The measuring tool 1 for example can for example have a real distance measuring range D between the ends 31 and 41 of 0-150 mm, or 0-300 mm, or 0-500 mm or other.

The measurement tool 1 may include a hooking point. The support 2 can for example be flat.

The support 2 may include an end of travel stop 100 for the movable spout 4, distant from the first spout 3.

The measurement tool 1 can comprise an autonomous energy supply, such as for example an electric battery or an electric battery, which can be removable and rechargeable with energy or non-rechargeable with energy. The cell or battery can be recharged for example by a photovoltaic cell provided on the measurement tool 1, for example on the top of the support 2 or on the top of another element of the tool 1.

The display unit 6 may include a backlight which can be switched on by pressing a sixth backlight button 77. In addition, the measurement tool 1 may comprise an outward lighting device, for example oriented towards the bottom of the support 2 to illuminate the plane P, being able to be actuated by the backlight button 77 or by another touch.

The backlight can be activated for a limited time, for example, possibly one minute or other. The display unit 6 can switch to a standby mode after a prescribed display time without modification of measurement or entry, which can be for example three minutes or other.

The measurement tool 1 may further include a seventh key 78 for starting and stopping the measurement tool 1.

The measurement tool 1 may also include a device 7 for lighting the man-machine interface. The man-machine interface 7 and / or the numeric keypad 71 and / or the aforementioned key (s) may be formed of buttons or be formed of touch keys displayed on a screen, or more generally of control ( s) manual.

In the machine T, the man-machine interface 7 is able to move the first and second virtual points 31 and 41 on the document P on the screen E respectively into the first and second positions R1, R2 or R3, R4, or others chosen and distinct from each other, so that the sensor 56 measures the distance D1 or D2 each time. During the first step, the distance sensor 56 of the machine T measures a first non-zero distance D1 on the virtual document P between the first and second positions R1, R2 where the first and second points 31, 41 are located. distance sensor 56 is configured to measure the distance existing on the virtual document P between the first virtual point 31 and the second virtual point 41, with reference for example to a reference of prescribed size of the document, which can be for example its width or length or others. This distance sensor 56 can be produced by any known computer program or function.
