- This coating E is a paste which is applied using a spreading tool, this coating can be a tile adhesive, a mortar for facades, a plaster or a smoothing coating or an adhesive.
- This coating E is used in the field of construction or that of the exterior or interior finishes of a building.
- This instrument 1 is in the form of a display tool 10.
- This instrument in the form of a display tool 10 comprises a plate 11 and gripping means 12. The gripping means are attached to the plate 11 or are made of material with said tray.
- the plate 11 is in the form of a blade 110 made of a metallic or plastic material of the polymer or rubber type.
- This blade 110 has a shape that can vary, that is to say that it can be or be inscribed in a square or rectangular or triangular shape or have any shape suitable for use.
- the plate 11 extends along a first direction and a second direction.
- the length along the first direction is greater than the length along the second direction.
- Blade 110 has a flat profile or may have a more complex profile with an inclined or curved portion.
- the blade 110 optionally comprises a toothing 111 arranged at least partially on the periphery of the blade 110.
- the gripping means 12 comprise at least one handle 120.
- This handle 120 comprises at least one pillar 121 and one handle 122, as in the case of a trowel or a trowel.
- the handle 120 comprises a handle and two pillars 121 as shown in Figure 2.
- the pillar(s) 121 extend from the blade 110 forming the plate 11. This pillar(s) extend orthogonally or at an angle to the plane of the plate 12.
- the handle 120 extends along the first direction of the plate 11 .
- the gripping means 12 can take on different configurations.
- a first configuration consists in having two handles 120. These handles 120 comprise one or two pillars 121 . The positioning of these handles 120 is made so that they extend parallel to each other.
- the gripping means comprise a single handle.
- This single 120 handle extends transversely to the length of the tray.
- the instrument 1 comprises gripping means 12 comprising at least one handle 120 from which a blade 110 extends.
- the handle can extend in the continuity of the plane of the blade 110 as in the case of a putty knife or a smoothing rule, or form a continuous or discontinuous projection in a direction transverse to the blade 110 as in the case of a trowel
- the instrument 1 for determining the ability or the ease of a coating to be spread further comprises a measuring module 13.
- This measuring module 13 is arranged to allow a measurement of the capacity of a coating E to be spread.
- a coating E is intended to be applied on a surface, the coating extends to apply so as to be the most evenly distributed, the coating is therefore spread.
- the force sensor 130 is arranged to measure the force exerted by the user when spreading the coating. Indeed, the principle is that the easier it is to spread the coating E, the greater the force exerted for the spreading operation.
- the force sensor 130 is a sensor of the strain gauge or deformation gauge 131 type. This deformation gauge 131 comprises turns whose resistance varies according to the deformation. This strain gauge 131 can be in the form of a box comprising the various elements of the strain gauge or else in the form of a sheet carrying the metal wires and a measurement circuit connected to said sheet. This strain gauge 131 is connected to a control unit. In a first embodiment visible in Figure 3, the force sensor
- the pillar(s) 121 undergo a stress which tends to deform it(ies). This stress is an addition of a tangential and a normal force.
- the strain gauge 131 is then placed on at least one pillar 121 so as to be able to detect the force resulting from the tangential force and the normal force exerted on said pillar.
- the amplitude of this resulting force is representative of the force exerted by the user so that the higher this amplitude, the less the coating is easy to spread.
- Figures 10a and 10b show the instrument 1 according to the invention placed in the spreading position while Figure 10b shows this same instrument subjected to the constraint of the user.
- Figure 10a shows the axis X of the pillar 121.
- Figure 10b shows that, under the effect of the stress exerted by the user, the axis X of the pillar becomes the axis X' offset angularly. This shift comes from the stress which tends to twist the pillar 121.
- the strain gauge 131 is then placed on at least one pillar 121 so as to be able to detect the force resulting from the tangential force and the normal force exerted on said
- each pillar has a strain gauge 131.
- These two pillars are used for large tools thus allowing better gripping. Having one strain gauge 131 per pillar allows, firstly, to have a reliability effect since if a gauge 131 were to malfunction, it would be possible to detect it. Secondly, it allows to analyze the movement of the user. Indeed, with two strain gauges 131 placed at a distance from each other, it is possible to know the distribution of the force of the user.
- the force sensor or sensors 130 are arranged in the pillar or pillars 121.
- the pillar or pillars can be hollow to allow a force sensor to be inserted into a pillar.
- each pillar can comprise at least two strain gauges 131 to have access to the tangential force and the normal force and not only the resultant force.
- the strain gauge 131 is arranged at the level of the base of at least pillar 121. Indeed, in this interface zone between the plate 11 and at least one pillar 121 ways to gripping, constraints are present during the operation of spreading a coating.
- strain gauge 131 is arranged at the interface between the plate 11 and at least one pillar 121 of the gripping means.
- This strain gauge 131 is then placed at the interface between the plate 11 and at least one pillar 121 of the gripping means.
- This strain gauge 131 is preferably encapsulated in a material, for example of the plastic type, allowing the transmission of strains to said strain gauge 131 .
- Said pillar 121 can be dug and include a housing in which the strain gauge 131 is placed so that said strain gauge 131 is both at the interface between the pillar and the plate and in said pillar as shown in Figure 17
- the plate can itself also comprise a housing.
- FIGS. 11a and 11b show the operation of the force sensor 130 of this second embodiment.
- Figure 11a shows the instrument 1 according to the invention placed in the spreading position while Figure 11b shows this same instrument subjected to the constraint of the user.
- Figure 11a shows the Y axis of the pillar 121.
- Figure 11b shows that, under the effect of the stress exerted by the user, the Y axis of the pillar becomes the Y' axis shifted angularly. This offset comes from the stress which tends to crush the pillar 121 .
- two strain gauges 131 are used. These two strain gauges 131 are arranged to allow, during the movement consisting in spreading a coating E, to better characterize the strain exerted. Indeed, it is possible to have the two strain gauges 131 stretched or crushed in the same way or to have a strain gauge 131 undergoing a crushing while the other strain gauge undergoes a stretching.
- the strain gauge 131 is arranged at the plate. Indeed, during the coating spreading step, a deformation of the plate appears. This deformation comes from the fact that the user, to spread the coating, tends to scrape the plate of the trowel on the surface to be coated. This scraping leads to the appearance of stresses at the level of the plate 11 between the movement of use and the friction of the scraping which tend to oppose this movement. The deformation thus takes place along an axis perpendicular to the direction of the spreading movement.
- a strain gauge 131 used in this third embodiment comprises presented in the form of a wire 132 arranged in a multitude of parallel portions. These parallel portions are connected to each other by curved portions.
- the wire 132 is connected to a control unit 133 of the measurement module 13.
- the strain gauge 131 is arranged on the plate so that the parallel portions are parallel to the second direction of the plate 11 . This second direction is also the direction in which the trowel is set in motion to operate the spreading of the coating.
- FIGS. 12a and 12b The operation of the force sensor of this third embodiment can be seen in FIGS. 12a and 12b.
- Figure 12a shows the instrument 1 according to the invention placed in the spreading position while Figure 12b shows this same instrument subjected to the constraint of the user.
- Figure 12a shows the z axis of the pillar 121.
- Figure 12b shows that, under the effect of the constraint exerted by the user, the Z axis of the pillar becomes the angularly offset Z* axis. This offset comes from the stress which tends to crush the pillar 121 .
- wire 132 is arranged in plate 11 .
- the plate is likely to be made of a material of the plastic or rubber type. Such a material makes it possible to overmold the wire 132 of the strain gauge 131 .
- the measurement module 13 thus provides data making it possible to compare the spread of different coatings.
- the test of the different coatings consists in spreading, on a reference surface, an identical quantity of coating. This test allows, for each coating, to recover data.
- This data is, in particular, data relating to the force exerted on the trowel by the user. These data relating to the constraint are carried out temporally. It is understood by this that the measurements taken by the strain gauges 131 are taken at regular intervals. This allows to have the evolution of the stress applied by the user on the trowel during the spreading step of the coating. Curves of forces as a function of time are obtained like those illustrated in FIG. 13. These curves C are thus studied to determine which coating is the easiest to spread.
- the number of peaks corresponds to the number of gestures necessary to spread said coating. It is assumed that a large number of gestures means that the coating is more difficult to spread because it requires more gestures.
- the number of strokes per minute is significant of a capacity, of an ease of the coating E to be spread. Indeed, a coating E which is difficult to spread requires, at equal force, a duration to be spread which is greater. Consequently, if the measurement module 13 detects a greater number of movements then this means that the user spreads the coating more easily.
- This data relating to the number of gestures per minute should be compared to the data relating to the duration of the peaks. Indeed, if the duration of the peaks is large then this may mean that the number of peaks per minute will decrease, which means that the coating E is more difficult to spread. It can also mean that the movements of the user are ample so that a larger surface is coated with the same gesture. But it can also mean that the movement is slow and therefore the operation of spreading the coating is more difficult.
- the association with speed or acceleration information can provide a better understanding.
- this value also makes it possible to assess the ability of said coating to be spread. Effectively, it is assumed that the lower the spreadability of a coating E, the lower the slope will be. This is due to the viscosity of the coating E which will be lower and which therefore has a greater resistance to spreading.
- This data can be analyzed by the user or by computer to compare the data for each coating and determine which coating seems to have the easiest spread.
- Figure 14a shows curves of force versus time for four plasters A, B, C (standard plaster) and D.
- Figure 14b illustrates the average forces calculated for each plaster. This shows that the standard plaster C is the one with the highest average strength, so it requires more force to spread. Furthermore, it can be seen that render C requires a longer spreading step (80 seconds against 70 seconds or less for renders A, B and D).
- a second possible application is the use of these data of maximum force, average force, number of strokes per minute to compare the surfaces to be coated. Indeed, if these data can be used for the comparison of different coatings on a reference surface, the opposite consisting in comparing different surfaces to be coated with a reference coating E is possible. This possibility comes from the fact that each material used as substrate on which a coating E is spread has its own surface characteristics, in particular the surface state characteristics.
- Figure 16 thus shows the energy expended by an operator for different mortars for different surfaces.
- the mortar M3, for each of the surfaces S1, S2, S3, requires more energy for its spreading than the mortar M2, the latter itself requiring more energy than the mortar M1.
- looking at the M2 mortar it is possible to see that the S3 surface requires more energy than the S2 surface which, itself, requires more energy than the S1 surface.
- Another application consists in using the instrument 1 according to the invention to monitor the well-being of the user.
- This need for well-being comes from the fact that handling a tool for spreading such as a trowel can be difficult for the user if the coating or the surface causes difficulty in spreading said coating.
- This difficulty entails, for the user, the need to force the movement of his wrist or to spend more time for the operation of spreading said coating. Consequently, the user may experience discomfort.
- the data relating to the stress applied for the spreading of a coating E can be used to provide an indication of comfort.
- the data relating to the force, maximum or average applied by the user to carry out the said spreading of the coating if the maximum force and/or the average force exceed a predefined threshold then the display operation is said to be uncomfortable and an indication of this discomfort is transmitted.
- This indication can be an audible or vibratory or luminous signal.
- the instrument according to the invention comprises a luminous or vibratory or sound device to allow this indication.
- said instrument may further comprise other sensors.
- the instrument 1 further comprises an inclination sensor.
- This inclination sensor is, for example, a gyroscope installed at the level of a pillar 121 .
- This inclination sensor is thus able to measure the angle between the plane of the ground and the pillar in order to see the inclination of the latter.
- the inclination sensor measures the amplitude of the inclination taken by the instrument during the spreading operation.
- This amplitude is representative of the movement of the wrist of the user.
- a large measured amplitude means that the user's wrist is under strong stress.
- the repetition of such a solicitation can lead to the appearance of discomfort or even musculoskeletal disorders.
- having an angular amplitude greater than 90 degrees can lead to the appearance of a warning signal.
- the association of an amplitude of movement and a duration makes it possible to detect an uncomfortable or comfortable movement.
- This amplitude can also be associated with the force values (maximum, average). It is thus assumed that the more the coating E is difficult to spread (force required to spread said high coating) the more the operator will tend to force his movement and therefore the amplitude will increase.
- another characteristic representative of comfort is the weight of the coating E used. Indeed, the user who coats a surface sometimes uses the plate 11 of the tool used to spread like the trowel as an extra surface to place the coating E there before spreading it. However, if the mass is too large, the feeling of heaviness may appear at the level of the user's wrist, which can lead to muscle fatigue and therefore less efficiency in the operation of spreading said coating.
- the plate 11 then serves as a scale since the mass of plaster can be measured using the force sensor 130 arranged on at least one of the pillars.
- the notion of comfort is linked to the ease of a coating to be spread also depends on the quantity of coating to be spread. Indeed, the spreading comfort of a coating varies according to the quantity of coating that the user deposits on the surface to be coated, the more this quantity is important and the more the comfort is degraded but if the quantity is too low then the spreading efficiency will be low. This is because an X amount of plaster requires more force from the user to spread than an X/2 amount.
- the present invention is thus capable of determining whether the amount of coating E taken by the user is optimal.
- the force sensor 130 is used to measure the force applied by the user on the trowel to carry out the spreading of the coating. This measured force is thus compared with a reference value.
- This reference value can be known manufacturer data or can be a value determined by the trowel itself.
- This self-determination of the reference value by the trowel consists of a continuous analysis of the applied force. Indeed, it is conceivable that, for a given coating, the force applied to the trowel to spread said coating E may vary according to the user and his morphology.
- the control unit 133 of the measurement module 13 is able, via an algorithm, to measure the force continuously or at regular intervals. This measurement continuously or at regular intervals is analyzed by said control unit 133 to extract therefrom the optimum quantity of coating E.
- the control unit 133 is also capable of extracting a user profile P and saving it.
- This user profile P is representative of the way of spreading of the user.
- This profile includes in particular an indication of the average value of the force and a maximum value, C curves, i.e. the force as a function of time, or even data on the inclination.
- This profile P can be completed or refined using the second example.
- said instrument is capable of measuring the quantity of plaster by measuring the weight of said plaster when the latter is placed on the plate of the trowel. This weight measurement can thus be correlated with the force measured during the coating spreading step.
- the algorithm of the control unit 133 is capable of associating the measurement of the weight of the coating with that of the force necessary to spread this weight to precisely determine the behavior of the user, in particular the value of the average force which can, for a given coating, vary according to the user.
- This profile P can then be used as a reference.
- the control unit 133 can compare the force values subsequently measured with the reference profile P.
- the algorithm of the control unit 133 is then able to detect variations in the force values. These variations can be analyzed so that excessive variations are considered to be a sign that the quantity of coating to be spread is too great.
- the user profile P is such that it evolves, that is to say that it is fed during the user of the tool with the measured data to be refined.
- the control unit 133 is then able to generate an alert signal in light or sound form.
- the control unit 133 can include a communication module sending the alert signal to a mobile terminal or a communication module. signaling generating an audible and/or luminous signal.
- This theoretical ideal profile includes on the average value of the force and a maximum value, C curves, see data on the inclination.
- This profile P can be completed or refined using the second example
- the measuring means 13 can include other types of sensors. These other types of sensors are speed or acceleration sensors. These sensors then make it possible to obtain data relating to the speed, the acceleration of the instrument during the stage of display. These data are useful because they are representative of the movement operated by the user to spread said coating. Thus, it is assumed that the greater the acceleration and/or speed measured, the easier the coating is to spread because the consistency of the coating does not slow down the movement of the user.
- the data from the measuring means are used to extract, from a force and a speed as a function of time, a work, that is to say the energy expended by the 'user.
- measuring means 13 having several sensors, it is possible to have a sensor arranged on the pillar and another in the pillar or a sensor on the plate and another on the pillar, the different sensors being able to be installed differently.
