Description

DISPOSITIF DE MESURE AMOVIBLE  REMOVABLE MEASURING DEVICE
Arrière-plan de l'invention Background of the invention
La présente invention a trait au domaine des dispositifs de mesure associés à un équipement de sports tel qu'une raquette et en particulier une raquette de tennis munie d'un manche, d'un tamis, de deux branches reliant le manche de la raquette au tamis de la raquette.  The present invention relates to the field of measuring devices associated with sports equipment such as a racket and in particular a tennis racket equipped with a handle, a sieve, two branches connecting the handle of the racket to sieve of the racket.
Les dispositifs de mesure pour raquettes de tennis sont connus et se présentent sous différentes formes. Ces dispositifs de mesure sont destinés à mesurer des paramètres physiques, comme par exemple la vitesse la rotation ou bien encore l'accélération de la raquette.  Measuring devices for tennis rackets are known and come in different forms. These measuring devices are intended to measure physical parameters, such as, for example, the speed of rotation or even the acceleration of the racket.
Ces dispositifs de mesure sont intégrés à la structure de la raquette afin d'améliorer les prises de mesures. Pour autant, cela implique le fait que l'utilisateur utilise uniquement la raquette, incorporant ce dispositif, à l'entraînement. En effet, les raquettes équipées de matériels permettant de réaliser des mesures sont interdites durant les tournois. On comprend dès lors que l'utilisateur ne pourra pas s'entrainer et participer à des tournois avec la même raquette. En outre, l'utilisateur de la raquette incorporant le dispositif de mesure peut être mal à l'aise avec la raquette qui sera forcément différente de la raquette utilisée lors des tournois. On comprend bien les inconvénients de ce type de dispositif qui manque de flexibilité et d'adaptabilité pour l'utilisateur.  These measuring devices are integrated into the structure of the racket to improve measurements. However, this implies that the user only uses the racket, incorporating this device, the drive. Indeed, rackets equipped with equipment to perform measurements are prohibited during tournaments. We therefore understand that the user will not be able to train and participate in tournaments with the same racket. In addition, the user of the racket incorporating the measuring device may be uncomfortable with the racket which will necessarily be different from the racket used in tournaments. We understand the disadvantages of this type of device that lacks flexibility and adaptability for the user.
Il est également connu des dispositifs de mesure amovibles par rapport à la raquette.  It is also known removable measuring devices in relation to the racket.
La présente invention concerne plus particulièrement un dispositif de mesure qui comporte un boîtier qui comprenant :  The present invention more particularly relates to a measuring device which comprises a housing which comprises:
• une première portion ayant une face avant, ainsi qu'une face arrière présentant une surface plane configurée pour venir en appui contre au moins les bords latéraux des branches, et  A first portion having a front face and a rear face having a flat surface configured to abut against at least the lateral edges of the branches, and
• une seconde portion faisant saillie depuis la face arrière, ladite seconde portion étant configurée pour venir se loger entre les deux branches tout en prenant appui contre les bords intérieurs lorsque ledit dispositif de mesure est monté sur ladite raquette,  A second portion protruding from the rear face, said second portion being configured to be housed between the two branches while bearing against the inner edges when said measuring device is mounted on said racket,
le boîtier présentant une direction longitudinale qui est parallèle au manche lorsque ledit dispositif est monté sur ladite raquette, ledit boîtier comportant une batterie et un circuit électronique relié électriquement à la batterie. the housing having a longitudinal direction which is parallel to the handle when said device is mounted on said racket, said housing comprising a battery and an electronic circuit electrically connected to the battery.
Un tel dispositif est notamment décrit dans le document FR 2829700. Il décrit l'utilisation d'un boîtier venant se loger entre les deux branches. Le boîtier comporte sur sa face arrière un plot solidaire d'un bloc de mousse. Le bloc de mousse est disposé entre les branches et présente des propriétés de déformation. Ce dispositif présente plusieurs inconvénients. En effet, tout d'abord le bloc de mousse présentant des propriétés de déformation aura comme inconvénient de s'user au cours de son utilisation. En outre, le boîtier est relié au bloc de mousse au moyen d'un plot situé sur la face arrière. Ainsi, on comprend que le boîtier est susceptible d'entrer en rotation lors de l'utilisation du dispositif de mesure. En conséquence, la prise de mesure par le dispositif est perturbée. L'efficacité du dispositif de mesure est donc très fortement diminuée dès lors qu'il ne permet pas d'obtenir des mesures précises et fiables.  Such a device is described in particular in document FR 2829700. It describes the use of a housing that is housed between the two branches. The housing comprises on its rear face a pad integral with a block of foam. The foam block is disposed between the branches and has deformation properties. This device has several disadvantages. Indeed, first of all the foam block having deformation properties will have the drawback of being worn during its use. In addition, the housing is connected to the foam block by means of a stud located on the rear face. Thus, it is understood that the housing is likely to rotate when using the measuring device. As a result, measurement by the device is disturbed. The effectiveness of the measuring device is therefore greatly reduced since it does not provide accurate and reliable measurements.

L'invention a notamment pour objet d'améliorer la prise des mesures du dispositif de mesure.  The object of the invention is in particular to improve the measurement of the measuring device.
Ce but est atteint par le fait que, considérée selon la direction longitudinale du boîtier, la seconde portion présente une extrémité supérieure, une extrémité inférieure et des faces latérales opposées conformées pour prendre appui contre les bords intérieurs des branches, la largeur de la seconde portion étant décroissante vers l'extrémité inférieure, et la surface plane présente deux zones planes disposées de part et d'autre des faces latérales de la seconde portion, lesdites zones planes étant conformées pour venir en appui contre les bords latéraux des branches lorsque le dispositif de mesure est monté sur la raquette.  This object is achieved by the fact that, considered in the longitudinal direction of the housing, the second portion has an upper end, a lower end and opposite lateral faces shaped to bear against the inner edges of the branches, the width of the second portion. being decreasing towards the lower end, and the plane surface has two plane zones arranged on either side of the lateral faces of the second portion, said flat zones being shaped to bear against the lateral edges of the branches when the measure is mounted on the racket.
On comprend donc que les faces latérales de la seconde portion, selon l'invention, se positionnent contre les bords intérieurs des branches de la raquette lorsque le dispositif est monté sur la raquette.  It is therefore understood that the side faces of the second portion, according to the invention, are positioned against the inner edges of the branches of the racket when the device is mounted on the racket.
Ainsi, l'appui réalisé par chacune des faces latérales opposées de la seconde portion contre les bords intérieurs des branches et l'appui réalisé par chacune des zones planes de la surface plane contre les bords latéraux des branches offrent une stabilité accrue du boîtier par rapport à la raquette. Autrement dit grâce à l'invention, le boîtier est bloqué en rotation par rapport à la raquette selon un axe perpendiculaire à la direction longitudinale. Thus, the support provided by each of the opposite side faces of the second portion against the inner edges of the branches and the support provided by each of the flat areas of the flat surface against the edges Lateral branches provide increased stability of the case relative to the racket. In other words, thanks to the invention, the casing is locked in rotation relative to the racket along an axis perpendicular to the longitudinal direction.
Un autre avantage est que les faces latérales et les zones planes permettent de positionner rapidement et de manière fiable le boîtier. Encore un autre intérêt du dispositif selon l'invention est qu'il peut se monter sur différents modèles de raquette.  Another advantage is that the side faces and the flat areas allow the housing to be positioned quickly and reliably. Yet another advantage of the device according to the invention is that it can be mounted on different models of racket.
Ainsi grâce à l'invention, le boîtier est facilement positionné, correctement calé de sorte que la qualité des mesures prises par le dispositif de mesure est améliorée.  Thus, thanks to the invention, the housing is easily positioned, properly wedged so that the quality of the measurements taken by the measuring device is improved.
En outre, selon un aspect avantageux, les deux zones planes s'étendent selon la longueur de la seconde portion. Dit autrement, les deux zones planes bordent les faces latérales de la seconde portion, ce qui améliore encore la tenue du boîtier.  In addition, according to an advantageous aspect, the two planar zones extend along the length of the second portion. In other words, the two planar zones border the lateral faces of the second portion, which further improves the behavior of the housing.
Avantageusement, les deux zones planes sont perpendiculaires aux faces latérales opposées de la seconde portion. L'intérêt est d'obtenir deux zones planes qui vont réaliser un appui maximum avec les bords latéraux des branches de la raquette. Ainsi, on obtient une plus grande stabilité du boîtier lorsque le dispositif est monté sur la raquette. Selon un mode préférentiel, considérée selon la direction longitudinale, la première portion présente une partie supérieure et une partie inférieure, et la seconde portion fait saillie depuis la partie supérieure de la première portion.  Advantageously, the two planar zones are perpendicular to the opposite side faces of the second portion. The interest is to obtain two flat areas that will achieve maximum support with the side edges of the branches of the racket. Thus, greater stability of the housing is obtained when the device is mounted on the racket. According to a preferred embodiment, considered in the longitudinal direction, the first portion has an upper portion and a lower portion, and the second portion projects from the upper portion of the first portion.
Avantageusement, la partie inférieure présente une face plane destinée à venir en appui contre le bord supérieur du manche de la raquette.  Advantageously, the lower portion has a flat face intended to bear against the upper edge of the handle of the racket.
On comprend que la seconde portion, faisant saillie depuis la partie supérieure de la première portion, permet de positionner et caler le boîtier entre les deux branches de la raquette, tandis que la partie inférieure, venant en appui contre la raquette offre une surface d'appui supplémentaire pour améliorer encore la stabilité du dispositif.  It is understood that the second portion, projecting from the upper portion of the first portion, makes it possible to position and wedge the housing between the two branches of the racket, while the lower part, resting against the racket, offers a surface of additional support to further improve the stability of the device.
De manière particulièrement avantageuse, la partie inférieure de la première portion présente une épaisseur inférieure à l'épaisseur de la partie supérieure de la première portion grâce à quoi, lorsque l'utilisateur place sa main sur la partie supérieure du manche et sur la partie inférieure du boîtier, celui-ci est peu gêné par la présence du boîtier. Particularly advantageously, the lower portion of the first portion has a thickness less than the thickness of the upper portion of the first portion, whereby when the user place his hand on the upper part of the handle and on the lower part of the case, it is not bothered by the presence of the case.
De manière préférentielle, la longueur de la seconde portion, considérée selon la direction longitudinale du boîtier est au plus égale à la moitié de la longueur du boîtier. On comprend ainsi qu'une surface de la face arrière de la partie inférieure est disponible pour venir, notamment, en appui contre les bords latéraux des branches de la raquette. Avantageusement, la partie supérieure présente une largeur supérieure à la largeur de la partie inférieure, de sorte que les bords latéraux du boîtier sont inclinés par rapport à la direction longitudinale.  Preferably, the length of the second portion, considered in the longitudinal direction of the housing is at most equal to half the length of the housing. It is thus understood that a surface of the rear face of the lower part is available to come, in particular, bearing against the side edges of the branches of the racket. Advantageously, the upper portion has a width greater than the width of the lower portion, so that the lateral edges of the housing are inclined relative to the longitudinal direction.
On comprend que, les bords latéraux inclinés peuvent être réalisé, par exemple, pour se conformer à la forme des branches de la raquette. Ainsi, l'espace occupé par le boîtier ne génère pas de gêne dans le mouvement de la raquette. Le boîtier perturbe peu la pénétration de la raquette dans l'air. Il en est de même pour les sensations de l'utilisateur par rapport à une raquette non équipée du dispositif de mesure.  It is understood that the inclined lateral edges can be made, for example, to conform to the shape of the branches of the racket. Thus, the space occupied by the housing does not cause discomfort in the movement of the racket. The case disturbs little the penetration of the racket in the air. It is the same for the sensations of the user compared to a racket not equipped with the measuring device.
Selon un mode préférentiel, la surface plane présente une zone inférieure plane située au niveau de la partie inférieure de la première portion. En outre, la zone inférieure est conformée pour venir en appui contre au moins les bords latéraux des branches. On comprend que la zone inférieure plane est distincte des deux zones planes précitées, ces dernières se trouvant en partie supérieure de la première portion, de part et d'autre de la seconde portion.  In a preferred embodiment, the flat surface has a flat lower zone located at the lower portion of the first portion. In addition, the lower zone is shaped to abut against at least the lateral edges of the branches. It will be understood that the flat lower zone is distinct from the two aforementioned flat zones, the latter being in the upper part of the first portion, on either side of the second portion.
Comme mentionné ci-dessus, la zone inférieure plane de la surface plane permet d'obtenir une plus grande surface d'appui contre les bords latéraux des branches.  As mentioned above, the flat lower zone of the flat surface provides a greater bearing surface against the lateral edges of the branches.
Selon un mode préférentiel, le boîtier comporte en outre au moins une bande de fixation prenant appui sur au moins l'une des parties supérieure ou inférieure de la première portion, et destinée à être fixée à au moins l'une des branches ou au manche de la raquette lorsque le dispositif est monté sur la raquette.  According to a preferred embodiment, the housing further comprises at least one fastening strip bearing on at least one of the upper or lower portions of the first portion, and intended to be fixed to at least one of the branches or the handle racket when the device is mounted on the racket.
En outre, les bandes de fixation peuvent être de type Velcro, en matériau élastique ou encore une bande de fixation peut comporter un système à cran.  In addition, the fastening strips may be Velcro type, elastic material or a fastening strip may comprise a notch system.
On comprend que la bande de fixation vient renforcer la stabilisation du boîtier vis-à-vis de la raquette. En d'autres termes, la bande de fixation vient améliorer le maintien du boîtier monté sur la raquette et ainsi la précision des mesures du dispositif de mesure en est améliorée. It is understood that the fastening strip reinforces the stabilization of the case vis-à-vis the racket. In other words, the fastening strip improves the maintenance of the box mounted on the racket and thus the measurement accuracy of the measuring device is improved.
Avantageusement, la première portion comporte en outre au moins un passant disposé sur la face avant du boîtier afin de recevoir la bande de fixation. La coopération de la bande avec le passant permet encore d'améliorer le maintien du boitier à la raquette. De préférence, le boîtier est pourvu d'au moins une paire de passants disposés sur la partie supérieure.  Advantageously, the first portion further comprises at least one passer disposed on the front face of the housing to receive the fastening strip. The cooperation of the band with the passer still allows to improve the maintenance of the racket box. Preferably, the housing is provided with at least one pair of loops disposed on the upper part.
Ainsi, lorsque la bande de fixation n'entoure plus au moins une branche de la raquette, ladite bande de fixation reste relié au boîtier de sorte que la bande de fixation ne puisse pas être égaré. De plus les passants permettent de faciliter le montage du dispositif sur la raquette.  Thus, when the fastening strip no longer surrounds at least one branch of the racket, said fastening strip remains connected to the case so that the fastening strip can not be lost. Moreover passers-by make it easier to mount the device on the racket.
Selon un autre mode de réalisation, la bande de fixation peut être solidarisée au moyen d'un adhésif au boîtier.  According to another embodiment, the fastening strip may be secured by means of an adhesive to the housing.
De manière préférentielle, le circuit électronique comporte au moins un accéléromètre, qui est de préférence disposé dans la partie inférieure de la première portion.  Preferably, the electronic circuit comprises at least one accelerometer, which is preferably arranged in the lower part of the first portion.
On comprend que l'accéléromètre disposé ainsi a comme avantage d'être positionné de manière stable. L'intérêt est d'obtenir un minimum de variations de mouvement de l'accéléromètre par rapport à son référentiel et ainsi obtenir une prise de mesure efficace par le dispositif de mesure.  It is understood that the accelerometer thus disposed has the advantage of being positioned stably. The interest is to obtain a minimum of variations of movement of the accelerometer with respect to its reference system and thus obtain effective measurement by the measuring device.
De manière préférentielle, considérée dans le plan de la face arrière de la première portion, l'aire de la seconde portion est inférieure à l'aire de la surface plane, grâce à quoi le dispositif dispose sur la face arrière d'une surface relativement importante pour venir en appui contre les bords latéraux des branches et également sur la partie supérieure du manche.  Preferably, considered in the plane of the rear face of the first portion, the area of the second portion is less than the area of the flat surface, whereby the device has on the rear surface a relatively important to bear against the side edges of the branches and also on the upper part of the handle.
Selon un aspect particulièrement avantageux de la présente invention, la seconde portion présente la forme d'un bloc et les deux faces latérales opposées sont inclinées par rapport à la direction longitudinale du boîtier.  According to a particularly advantageous aspect of the present invention, the second portion has the shape of a block and the two opposite side faces are inclined relative to the longitudinal direction of the housing.
On comprend que l'intérêt est de se conformer aux bords intérieurs des branches pour obtenir un blocage en rotation du boîtier lorsque ce dernier est monté sur la raquette. En outre, de préférence mais non exclusivement, chacune des faces latérales opposées de la seconde portion forme un angle avec la direction longitudinale du boîtier, cet angle étant compris entre 10° et 30°. It is understood that the interest is to comply with the inner edges of the branches to obtain a locking rotation of the housing when the latter is mounted on the racket. In addition, preferably but not exclusively, each of the opposite side faces of the second portion forms an angle with the longitudinal direction of the housing, this angle being between 10 ° and 30 °.
Ainsi, les faces latérales opposées sont susceptibles d'être compatibles avec de nombreuses raquettes munies d'un manche, d'un tamis, de deux branches reliant le manche de la raquette au tamis de la raquette.  Thus, the opposite side faces are likely to be compatible with many rackets equipped with a handle, a sieve, two branches connecting the handle of the racket sieve of the racket.
Avantageusement, le bloc présente en outre une face inférieure, orientée transversalement par rapport à la surface plane, ladite face inférieure étant bombée. L'intérêt de la face inférieure bombée est de venir se conformer avec la partie supérieure du manche de la raquette comportant la jointure des branches de la raquette. Ainsi on comprend que la forme bombée vient en appui contre la jointure des branches. Ainsi un tel appui de la face inférieure améliore encore la stabilité du dispositif de sorte à améliorer la prise des mesures par le dispositif.  Advantageously, the block further has a lower face, oriented transversely to the flat surface, said lower face being curved. The interest of the convex underside is to come to comply with the upper part of the handle of the racket having the join of the branches of the racket. Thus we understand that the convex shape bears against the join branches. Thus such support of the underside further improves the stability of the device so as to improve the measurement by the device.
Avantageusement, le bloc est réalisé dans un matériau rigide, par exemple plastique. De préférence, mais pas exclusivement, le bloc est réalisé dans le même matériau que la première portion.  Advantageously, the block is made of a rigid material, for example plastic. Preferably, but not exclusively, the block is made of the same material as the first portion.
De manière préférentielle, au moins l'une des faces du bloc comprend en outre un revêtement antidérapant. On comprend que l'intérêt de disposer un revêtement sur l'une des faces du bloc est d'obtenir une augmentation des forces de frottement. En conséquence on obtient une meilleure adhérence de la face avec l'un des bords intérieurs des branches de la raquette, en conséquence de quoi on améliore encore le maintien.  Preferably, at least one of the faces of the block further comprises a non-slip coating. It is understood that the advantage of having a coating on one of the faces of the block is to obtain an increase in frictional forces. As a result we obtain a better adhesion of the face with one of the inner edges of the branches of the racket, as a result of which we further improves the maintenance.
En outre, de préférence, chacune des faces latérales opposées comporte un revêtement antidérapant grâce à quoi on obtient un très bon maintien du boîtier vis-à-vis de la raquette.  In addition, preferably, each of the opposite side faces has a non-slip coating whereby a very good retention of the case vis-à-vis the racket is obtained.
Préférentiellement, au moins l'une des zones planes est pourvue d'un élément antidérapant. Grâce à l'utilisation d'un élément antidérapant sur au moins l'une des zones planes, le boîtier obtient une meilleure adhérence sur la zone d'appui.  Preferably, at least one of the flat areas is provided with a non-slip element. Through the use of a non-slip element on at least one of the flat areas, the housing gets a better grip on the support zone.
De manière avantageuse, la hauteur de la seconde portion, considérée selon une direction perpendiculaire à ladite surface plane, est au moins égale à la moitié de la longueur du boîtier. L'intérêt est que la seconde portion comporte une hauteur suffisamment grande pour offrir une plus grande surface d'appui contre les bords intérieurs des branches de la raquette. Ainsi on comprend que la transmission des forces est mieux répartie sur l'ensemble de la surface des faces latérales opposées de la seconde portion. Advantageously, the height of the second portion, considered in a direction perpendicular to said planar surface, is at least equal to half the length of the housing. The interest is that the second portion has a height large enough to provide a greater support surface against the inner edges of the branches of the racket. Thus it is understood that the transmission of forces is better distributed over the entire surface of the opposite side faces of the second portion.
En outre, selon un aspect avantageux de l'invention, la seconde portion comporte un évidement formé à l'intérieur de ladite seconde portion. En d'autres termes, le bloc est creux. Avantageusement, le circuit électronique et/ou la batterie sont logés dans l'évidement. Préférentiellement, le circuit électronique est logé dans la première portion, tandis que la batterie est logée dans la seconde portion. Dans cette variante préférentielle, mais pas exclusive, la batterie est ainsi logée dans l'évidement de la seconde portion.  In addition, according to an advantageous aspect of the invention, the second portion comprises a recess formed inside said second portion. In other words, the block is hollow. Advantageously, the electronic circuit and / or the battery are housed in the recess. Preferably, the electronic circuit is housed in the first portion, while the battery is housed in the second portion. In this preferred embodiment, but not exclusive, the battery is thus housed in the recess of the second portion.
Un intérêt est d'obtenir une répartition des masses équilibrées sur l'ensemble du dispositif. Ainsi, le boîtier selon l'invention présente l'avantage de ne pas créer un déséquilibre de la raquette lors de son utilisation. De préférence mais non exclusivement, la seconde portion est formée en une seule pièce avec la première portion.  An interest is to obtain a distribution of balanced masses over the entire device. Thus, the housing according to the invention has the advantage of not creating an imbalance of the racket during use. Preferably, but not exclusively, the second portion is formed in one piece with the first portion.
Ainsi, on comprend que l'ensemble du boîtier offre une rigidité accrue et contribue au maintien en position du boîtier lors de son utilisation lorsqu'il est monté entre les branches de la raquette.  Thus, it is understood that the entire housing provides increased rigidity and helps maintain the position of the housing when used when mounted between the branches of the racket.
L'invention porte également sur une raquette munie d'un manche, d'un tamis, de deux branches ayant des bords intérieurs et latéraux, lesdites branches reliant le manche au tamis, et comportant un dispositif de mesure conforme à l'invention, dans laquelle les zones planes viennent en appui contre les bords latéraux des branches, et dans laquelle la seconde portion est logée entre les deux branches de sorte que les faces latérales de la seconde portion prennent appui contre les bords intérieurs des branches.  The invention also relates to a racket equipped with a handle, a sieve, two branches having internal and lateral edges, said branches connecting the handle to the sieve, and comprising a measuring device according to the invention, in which flat areas bear against the lateral edges of the branches, and wherein the second portion is housed between the two branches so that the lateral faces of the second portion bear against the inner edges of the branches.

Sur les figures 1 à 10, on a représenté un exemple d'un dispositif de mesure 10 selon l'invention monté sur une raquette 12 munie d'un manche 14, d'un tamis 16 et de deux branches 18 comprenant des bords intérieurs 20 et des bords latéraux 22. Les branches 18 permettent de relier le manche 14 de la raquette au tamis 16 de la raquette. Dans cet exemple non limitatif, il s'agit d'une raquette de tennis.  FIGS. 1 to 10 show an example of a measuring device 10 according to the invention mounted on a racket 12 provided with a handle 14, a sieve 16 and two branches 18 comprising inner edges 20 and side edges 22. The branches 18 are used to connect the handle 14 of the racket sieve 16 of the racket. In this non-limiting example, it is a tennis racket.
Dans cet exemple, le dispositif de mesure 10 est configuré pour mesurer au moins l'accélération de la raquette. A cet effet, il comprend au moins un accéléromètre. L'accéléromètre fait partie d'un circuit électronique qui sera décrit ci-dessous.  In this example, the measuring device 10 is configured to measure at least the acceleration of the racket. For this purpose, it comprises at least one accelerometer. The accelerometer is part of an electronic circuit that will be described below.
Généralement, les raquettes présentent une grande partie évidée situé entre le tamis 16, les bords intérieurs 20 des branches 18 et la partie supérieure 14a du manche où se rejoignent les branches 18 de la raquette 12.  Generally, snowshoes have a large hollow portion located between the sieve 16, the inner edges 20 of the branches 18 and the upper portion 14a of the handle where the branches 18 of the racket 12 meet.
En outre, en se référant aux figures 4 à 10, on constate que le dispositif de mesure 10 comporte un boîtier 24 qui comprend tout d'abord une première portion 26 ayant une face avant 28, une face arrière 30 qui présente une surface plane 32. Le boîtier 24 comporte un capot 29.  Furthermore, referring to FIGS. 4 to 10, it can be seen that the measuring device 10 comprises a housing 24 which firstly comprises a first portion 26 having a front face 28, a rear face 30 which has a flat surface 32 The housing 24 comprises a cover 29.
On comprend que la surface plane 32 de la surface arrière 30 est configurée pour venir en appui contre les bords latéraux 22 des branches 18, et dans cet exemple contre le bord supérieur du manche 14a. Le boîtier 24 s'étend selon une direction longitudinale D qui est parallèle au manche lorsque le boîtier 24 est monté sur la raquette 12. It is understood that the flat surface 32 of the rear surface 30 is configured to bear against the side edges 22 of the legs 18, and in this example against the upper edge of the handle 14a. The housing 24 extends in a longitudinal direction D which is parallel to the handle when the housing 24 is mounted on the racket 12.
Par ailleurs, on constate que le boîtier 24 comporte une seconde portion 34 faisant saillie depuis la face arrière 30 de la première portion 26. Dans cet exemple, la seconde portion 34 est rigide. Les première et seconde portions 26, 34 sont réalisées, dans cet exemple, dans un matériau rigide tel du plastique.  Furthermore, it is found that the housing 24 has a second portion 34 projecting from the rear face 30 of the first portion 26. In this example, the second portion 34 is rigid. The first and second portions 26, 34 are made, in this example, in a rigid material such as plastic.
On observe, sur les figures 4 et 5, que la seconde portion 34 est constituée d'une extrémité supérieure 40 et d'une extrémité inférieure 42. On s'aperçoit que la largeur de la seconde portion diminue lorsqu'on se dirige vers l'extrémité inférieure de la seconde portion 34. Par largeur de la seconde portion 34 on entend la dimension qui est perpendiculaire à la direction longitudinale D.  It can be seen in FIGS. 4 and 5 that the second portion 34 consists of an upper end 40 and a lower end 42. It can be seen that the width of the second portion decreases when moving towards the lower end of the second portion 34. By width of the second portion 34 is meant the dimension which is perpendicular to the longitudinal direction D.
En outre, la seconde portion 34 comporte deux faces latérales opposées 44 qui viennent prendre appui sur les bords intérieurs 20 des branches 18.  In addition, the second portion 34 has two opposite lateral faces 44 which bear on the inner edges 20 of the branches 18.
Dans cet exemple, les faces latérales opposées 44 sont inclinées par rapport à la direction longitudinale D du boîtier 24 en suivant la décroissance de la largeur de la seconde portion 34. L'utilisateur vient positionner la seconde portion 34 du boîtier en le faisant glisser le long des bords intérieurs des branches de la raquette jusqu'au moment où le déplacement selon la direction longitudinale vers la partie supérieure 14a du manche 14 n'est plus possible.  In this example, the opposite lateral faces 44 are inclined with respect to the longitudinal direction D of the housing 24 following the decrease of the width of the second portion 34. The user positions the second portion 34 of the housing by sliding the along the inner edges of the branches of the racket until the displacement in the longitudinal direction to the upper portion 14a of the handle 14 is no longer possible.
Sur la figure 7, on observe que les faces latérales 44 opposées forme chacune un angle a par rapport à la direction longitudinale D du boîtier 24 qui est compris entre 10° à 30°.  In FIG. 7, it can be seen that the opposite lateral faces 44 each form an angle α with respect to the longitudinal direction D of the housing 24 which is between 10 ° and 30 °.
Ainsi, les faces latérales 44 opposées viennent en appui contre les bords intérieurs 20 des branches 18. Dès lors, la seconde portion 34 sera dans l'impossibilité de pivoter autour d'un axe X perpendiculaire au plan P de la raquette 12 et situé sensiblement au centre de la seconde portion 34. Ainsi, le reste du boîtier est également dans l'impossibilité de pivoter dans le plan parallèle au plan P de la raquette 12.  Thus, the opposite lateral faces 44 bear against the inner edges 20 of the branches 18. Consequently, the second portion 34 will be unable to pivot about an axis X perpendicular to the plane P of the racket 12 and located substantially in the center of the second portion 34. Thus, the rest of the housing is also unable to pivot in the plane parallel to the plane P of the racket 12.
En outre, on constate que de part et d'autre de chacune des faces latérales opposées 44 sont disposées des zones planes 32a. On comprend que les zones planes 32a vont venir prendre appui contre les bords latéraux 22 des branches 18. En conséquence, on constate que les zones planes 32a vont permettre de diminuer la possibilité de la seconde portion 34 et de la première portion 26 de pivoter autour d'un axe Y parallèle au plan P et perpendiculaire à l'axe X situé sensiblement au centre de la seconde portion. In addition, it is found that on each side of each of the opposite side faces 44 are arranged planar areas 32a. It is understood that the flat areas 32a will bear against the lateral edges 22 of the branches 18. Consequently, it can be seen that the planar zones 32a will make it possible to reduce the possibility of the second portion 34 and the first portion 26 of pivoting about an axis Y parallel to the plane P and perpendicular to the axis X located substantially in the center of the second portion.
En outre, afin d'améliorer l'appui contre les bords latéraux 22 des branches 18, on remarque que les zones planes 32a sont perpendiculaires aux faces latérales 44 opposées de la seconde portion 28.  In addition, in order to improve the support against the lateral edges 22 of the branches 18, it is noted that the planar zones 32a are perpendicular to the opposite side faces 44 of the second portion 28.
On constate, sur la figure 9, que la première portion 26 est constituée d'une partie supérieure 26a et d'une partie inférieure 26b. Considérée selon la direction longitudinale D du boîtier 24, la partie supérieur 26a s'étend entre l'extrémité supérieur du boîtier et l'extrémité inférieure de la seconde portion, tandis que la partie inférieure 26b s'étend sous la partie supérieure 26a jusqu'à l'extrémité inférieure du boîtier 24.  It can be seen in FIG. 9 that the first portion 26 consists of an upper portion 26a and a lower portion 26b. Considered in the longitudinal direction D of the housing 24, the upper portion 26a extends between the upper end of the housing and the lower end of the second portion, while the lower portion 26b extends below the upper portion 26a until at the lower end of the housing 24.
Par ailleurs, on constate sur la figure 6 que la partie supérieure 26a présente une épaisseur el plus importante que l'épaisseur e2 de la partie inférieure 26b. Ainsi, comme on peut l'observer lorsque le dispositif est installé sur la raquette, la partie inférieure 26b du boîtier 24 offre un décroché qui gêne le moins possible l'utilisateur qui positionne sa main sur la partie supérieure du manche et sur la partie inférieure 26b du boîtier 24.  Furthermore, it can be seen in FIG. 6 that the upper portion 26a has a thickness e1 greater than the thickness e2 of the lower portion 26b. Thus, as can be seen when the device is installed on the racket, the lower portion 26b of the housing 24 offers a stall which hinders the least possible user who positions his hand on the upper part of the handle and on the lower part 26b of the housing 24.
On remarque sur la figure 6 que la seconde portion 34 a une longueur Ll, considérée selon la direction longitudinale D du boîtier, qui est inférieure à la moitié de la longueur L2 du boîtier.  Note in Figure 6 that the second portion 34 has a length L1, considered in the longitudinal direction D of the housing, which is less than half the length L2 of the housing.
On constate également que les deux zones planes 32a s'étendent selon la longueur Ll de la seconde portion 34. Dit autrement, les zones planes 32a bordent les faces latérales 44 de la seconde portion 34.  It can also be seen that the two planar zones 32a extend along the length L1 of the second portion 34. In other words, the plane zones 32a line the lateral faces 44 of the second portion 34.
On observe sur la figure 7 que la partie supérieure 26a de la première portion a une largeur 11 supérieure à la largeur 12 de la partie inférieure de la première portion.  It can be observed in FIG. 7 that the upper portion 26a of the first portion has a width 11 greater than the width 12 of the lower portion of the first portion.
On remarque également que les bords latéraux 46 du boîtier 24 sont inclinés. Dans l'exemple illustré, les bords latéraux 46 s'adaptent à la forme convergente des branches 18 de la raquette 12 afin d'apporter un aspect esthétique agréable à l'utilisateur. Sur les figures 1 à 3, le boîtier 24 est monté sur la raquette. It is also noted that the lateral edges 46 of the housing 24 are inclined. In the illustrated example, the lateral edges 46 adapt to the convergent shape of the branches 18 of the racket 12 in order to bring a pleasant aesthetic appearance to the user. In Figures 1 to 3, the housing 24 is mounted on the racket.
La surface plane 32 de la face arrière 30 comporte dans la partie supérieure 26a deux zones planes 32a venant en appui contre les bords latéraux 22 des branches 18 de la raquette 12. La seconde portion 34 faisant saillie entre les deux branches 18. La surface plane 32 présente en outre une zone inférieure plane 32b qui se situe au niveau de la partie inférieure 26b de la première portion 26. Sur les figues 1 à 3, on constate que la zone inférieure plane 32b vient en appui contre la partie supérieure du manche 14a, afin de permettre le blocage en rotation du boîtier autour de l'axe Y.  The flat surface 32 of the rear face 30 comprises in the upper part 26a two flat areas 32a bearing against the lateral edges 22 of the branches 18 of the racket 12. The second portion 34 projecting between the two branches 18. The flat surface 32 furthermore has a flat lower zone 32b which is located at the lower part 26b of the first portion 26. In FIGS. 1 to 3, it can be seen that the flat lower zone 32b bears against the upper part of the handle 14a. , in order to allow the locking in rotation of the housing around the axis Y.
En se référant aux figures 1 à 8, on observe que le dispositif comporte une bande de fixation 48 qui prend appui sur la partie supérieure de la face avant de la première portion du boîtier et entoure également les branches de la raquette.  Referring to Figures 1 to 8, it is observed that the device comprises a fastening strip 48 which bears on the upper part of the front face of the first portion of the housing and also surrounds the branches of the racket.
On remarque également que la face avant 28 de la première portion 24 du boîtier comporte deux paires de passants 50a, 50b. Une première paire 50a est située sur la partie supérieure 26a de la face avant 28 et une seconde paire 50b de passants est située dans la partie inférieure 26b de la face avant 28 de la première portion 26.  We also note that the front face 28 of the first portion 24 of the housing has two pairs of loops 50a, 50b. A first pair 50a is located on the upper portion 26a of the front face 28 and a second pair 50b of loops is located in the lower portion 26b of the front face 28 of the first portion 26.
Les deux passants 50a situés dans la partie supérieure 26a de la face avant 28 sont disposés face à face sur des bords latéraux 46 opposés du capot 29 du boîtier 24. La bande de fixation 48 traverse les deux passants 50a de la partie supérieure 26a de la face avant 28. Ensuite la bande de fixation vient entourer les branches 18 de la raquette 12.  The two loops 50a located in the upper part 26a of the front face 28 are arranged face to face on opposite side edges 46 of the cover 29 of the housing 24. The fastening strip 48 passes through the two loops 50a of the upper portion 26a of the 28. Then the fastening strip surrounds the branches 18 of the racket 12.
Lorsqu'une force F s'exerce selon la direction longitudinale D orientée vers le tamis de la raquette, la bande de fixation 48 s'appuie contre les branches 18 de la raquette 12, en sorte que le boîtier 24 subissant la force F est sensiblement maintenu en positon au moyen de la bande de fixation 48 qui contre la force F. Le boîtier 24 et la bande de fixation 48 sont reliés l'un à l'autre, ainsi, grâce aux appuis réalisés par la bande de fixation 48 contre les branches 18, le boîtier 24 restera sensiblement dans son logement situé dans la partie supérieure 14a du manche 14 de la raquette 12.  When a force F is exerted in the longitudinal direction D facing the sieve of the racket, the fastening strip 48 rests against the branches 18 of the racket 12, so that the casing 24 undergoing the force F is substantially maintained in position by means of the fastening strip 48 which against the force F. The housing 24 and the fastening strip 48 are connected to one another, thus, thanks to the supports made by the fastening strip 48 against the branches 18, the housing 24 will remain substantially in its housing located in the upper portion 14a of the handle 14 of the racket 12.
Les passants 50b situés dans la partie inférieure 26b sont susceptible de recevoir une autre bande de fixation similaire à la bande de fixation 48 situé dans la partie supérieure 26a de la première portion 26. Une telle bande de fixation selon un mode réalisation, passe au travers des deux passants 50b situés dans la partie inférieure et entoure la partie supérieure 14a du manche. The loops 50b located in the lower portion 26b are capable of receiving another fastening strip similar to the strip of fixation 48 located in the upper portion 26a of the first portion 26. Such fastening strip in one embodiment, passes through the two loops 50b located in the lower part and surrounds the upper portion 14a of the handle.
Sur la figure 9, on constate que le circuit électronique 38 comporte un accéléromètre 52. L'accéléromètre 52 est disposé dans la partie inférieure 26b de la première portion 26. Ainsi l'accéléromètre 52 est apte à réaliser des mesures précises dès lors qu'il est situé dans une partie très stable du dispositif 10.  In FIG. 9, it can be seen that the electronic circuit 38 comprises an accelerometer 52. The accelerometer 52 is disposed in the lower part 26b of the first portion 26. Thus, the accelerometer 52 is able to perform precise measurements as soon as it is located in a very stable part of the device 10.
Selon un mode de réalisation, non limitatif et non représentée, le circuit comporte une centrale inertielle comportant au moins l'accéléromètre précité et d'autres moyens de mesure. La centrale inertielle est disposée dans la partie inférieure de la première portion. Ainsi lorsque le boîtier est monté sur la raquette, la centrale inertielle prend les différentes mesures du mouvement. Les mesures sont ensuite transmises à un espace de stockage local ou distant.  According to one embodiment, not limiting and not shown, the circuit comprises an inertial unit comprising at least the aforementioned accelerometer and other measuring means. The inertial unit is disposed in the lower part of the first portion. So when the case is mounted on the racket, the inertial unit takes the various measures of movement. The measurements are then passed to a local or remote storage space.
Sur la figure 6, on constate dans cet exemple que la hauteur définie selon une direction perpendiculaire à la surface plane 32 est d'une longueur égale environ à la moitié de la longueur L2 du boîtier 24.  In FIG. 6, it can be seen in this example that the height defined in a direction perpendicular to the plane surface 32 is of a length equal to about half the length L2 of the housing 24.
Selon un mode de réalisation, non limitatif, on observe sur la figure According to one embodiment, which is not limiting, it is observed in the figure
7, que la seconde portion 34 se présente sous la forme d'un bloc présentant une face inférieure bombée 54. 7, that the second portion 34 is in the form of a block having a convex lower face 54.
En se référant aux figures 3 et 7, on remarque que lorsque le boîtier 24 est en position sur la raquette 12 dont la partie supérieure 14a du manche comporte la jointure entre les branches 18 et dont la forme de la jointure est une forme complémentaire de la face inférieure bombée 54, la face inférieure bombée 54 prend appui contre la surface 55 de la forme complémentaire.  Referring to Figures 3 and 7, it is noted that when the housing 24 is in position on the racket 12, the upper portion 14a of the handle comprises the joint between the branches 18 and whose shape of the joint is a complementary shape of the convex lower face 54, the convex lower face 54 bears against the surface 55 of the complementary shape.
En outre, on constate, toujours sur la figure 7, que si vue dans le plan de la face arrière de la première portion, l'aire de la seconde portion est inférieure à l'aire de la première portion. Un intérêt est de maximiser l'aire de la surface plane destinée à venir en contact avec le manche 14 ou les bords latéraux 22 des branches 18 de la raquette 12, afin de stabiliser le dispositif.  In addition, it can be seen, again in FIG. 7, that if viewed in the plane of the rear face of the first portion, the area of the second portion is smaller than the area of the first portion. An interest is to maximize the area of the flat surface intended to come into contact with the handle 14 or the lateral edges 22 of the branches 18 of the racket 12, in order to stabilize the device.
Selon un mode de réalisation, non limitatif, des revêtements antidérapants 56 sont disposés sur les faces latérales opposés 44 de manière à venir empêcher les glissements des faces latérales opposées par rapport aux bords intérieurs 20 des branches 18 de la raquette. According to a non-limiting embodiment, anti-slip coatings 56 are arranged on the opposite lateral faces 44 of in order to prevent slippage of the opposite lateral faces with respect to the inner edges 20 of the branches 18 of the racket.
En outre, on constate également que la surface plane comporte des éléments antidérapants 58. En particulier, mais de manière non limitative, des éléments antidérapants 58 sont disposés au moins dans les zones planes 32a situés de part et d'autres des faces latérales 44 de la seconde portion 34. On constate également que des éléments antidérapants 58 sont disposés sur la surface plane 32b située dans la partie inférieure de la première portion.  In addition, it can also be seen that the flat surface comprises non-slip elements 58. In particular, but in a nonlimiting manner, non-slip elements 58 are arranged at least in the plane zones 32a located on either side of the lateral faces 44 of the second portion 34. It is also noted that anti-slip elements 58 are disposed on the flat surface 32b located in the lower part of the first portion.
Selon la figure 2, les éléments antidérapants situés sur la surface plane 32 viennent en appui avec les bords latéraux 22 des branches 18 de la raquette 12 de manière à augmenter les frottements et ainsi les éléments antidérapants 58 participent à l'amélioration du maintien du boîtier par rapport aux branches de la raquette.  According to Figure 2, the non-slip elements located on the flat surface 32 abut with the side edges 22 of the arms 18 of the racket 12 so as to increase the friction and thus the non-slip elements 58 participate in improving the maintenance of the housing compared to the branches of the racket.
Sur la figure 10, on distingue que la première portion 26 et la seconde portion 34 comportent des évidements situés à l'intérieur du boîtier 24.  In FIG. 10, it can be seen that the first portion 26 and the second portion 34 have recesses located inside the housing 24.
On constate, avec les figures 9 et 10, que la batterie 36 est située dans l'évidement 34a de la seconde portion 34, tandis que la première portion est apte à recevoir le circuit électronique. Un intérêt de cette configuration, non limitative, est de répartir les masses du dispositif afin que son centre de gravité soit situé au plus proche de l'axe longitudinal de la raquette 12.  It can be seen, with FIGS. 9 and 10, that the battery 36 is located in the recess 34a of the second portion 34, while the first portion is able to receive the electronic circuit. An interest of this configuration, not limiting, is to distribute the masses of the device so that its center of gravity is located closest to the longitudinal axis of the racket 12.
En se référant aux différentes figures, on constate, en outre, que la première portion 26 et la seconde portion 34 forment une seule pièce, le capot 29 constituant une pièce rapportée.  Referring to the various figures, it is found, in addition, that the first portion 26 and the second portion 34 form a single piece, the cover 29 constituting an insert.
Selon un autre mode de réalisation non limitatif, non représenté, le dispositif 10 comporte la première portion, la seconde portion faisant saillie depuis la face arrière de la première portion et comporte une troisième portion symétrique à la première portion selon le plan P de la raquette. La troisième portion est également attachée à la seconde portion par une face arrière.  According to another non-limiting embodiment, not shown, the device 10 comprises the first portion, the second portion projecting from the rear face of the first portion and comprises a third portion symmetrical to the first portion along the plane P of the racket . The third portion is also attached to the second portion by a back face.
