  "abstract": "A ground-fixing system for a tire characteristics sensor housing (10) comprises: a fixing plate (1) comprising a plurality of recesses (2) of a given profile distributed over the surface of the fixing plate; and a plurality of fixing pins (3) of substantially corresponding profile, similarly distributed on a fixing face of said sensor housing (10), the shapes and dimensions of the recesses (2) and of the pins (3) for fixing being provided so as to allow, on the one hand, in a position of insertion of the pins, engagement of the latter in said recesses and, on the other hand, in a locking position of the pins, fixing of the sensor housing (10) on the fixing plate (1).",
  "claims": [
    "1. A ground-fixing system for a tire characteristics sensor housing, the system being designed to withstand severe stresses associated with vehicles driving over the sensor housing, and the system comprising: (i) a fixing plate comprising a plurality of recesses of a given profile distributed over a surface of the fixing plate; (ii) a plurality of fastening pins suitable for cooperating with the profiles of the recesses of the fixing plate, similarly distributed on a fixing face of the sensor housing with a degree of freedom in rotation so as to allow the fastening pins to be inserted and immobilized by simple rotation in the corresponding recesses, wherein shapes and dimensions of the recesses and of the fastening pins being provided so as to allow, in an insertion position of the fastening pins, engagement of the fastening pins in the recesses and, in a locking position of the fastening pins resulting from a rotation of the fastening pins, fixing of the sensor housing on the fixing plate, wherein the length of the fixing plate is greater than that of the measurement housing that is to be fixed, and the number of recesses is greater than the number of pins to be received in order to allow the housing to be positioned at a plurality of locations along the longitudinal axis L-L of the fixing plate, and wherein the fixing plate is fixed to the ground.",
    "2. The system according to claim 1, wherein an angular difference between the insertion position and the locking position is less than 300 degrees.",
    "3. The system according to claim 1, wherein the given profile is oblong, star-shaped, cross-shaped, or T-shaped.",
    "4. The system according to claim 1, wherein the given profile is oblong, and wherein each fastening pin comprises two edges that are substantially straight and mutually parallel and two substantially opposite curved edges with concave faces.",
    "5. The system according to claim 1, wherein the shapes and dimensions of the recesses of the fixing plate are suitable for the insertion of a fastening pin and for locking the fastening pin by rotation of substantially a quarter turn.",
    "6. The system according to claim 1, wherein the recesses have an oblong profile with two curved edges with convex faces, profiles and dimensions substantially complementary to the curved edges with concave faces of the fastening pins, to allow a fastening pin to cooperate, in the locking position, with a recess.",
    "7. The system according to claim 1, wherein each fastening pin comprises at least one immobilizing means limiting or preventing rotation.",
    "8. The system according to claim 7, wherein the at least one immobilizing means consists of a plurality of studs disposed on a face opposite the sensor housing.",
    "9. The system according to claim 7, wherein the at least one immobilizing means consists of at least one flexible immobilizing strip.",
    "10. The system according to claim 7, wherein the at least one immobilizing means consists of at least one friction bar.",
    "11. The system according to claim 1, wherein the fixing plate has a width greater than a width of the sensor housing, the plurality of recesses being distributed over substantially the entire width of the fixing plate."

  "description_excerpt": "The present invention relates to a ground-fixing system for a tyre characteristics sensor housing.\n\nDocument WO 2014202747 describes a system for measuring the thickness of a layer of rubbery material of a tyre. It takes the form of a housing that is to be fixed to the ground. In use, this type of housing is subject to high stresses owing to numerous vehicles of all types, including trucks, driving over it. Despite these high stresses, the housing must not move or lift. The housings are therefore often fixed to the ground by means of significant infrastructure in the ground. This infrastructure involves major work, which is both time-consuming and costly. Moreover, if a housing proves to be badly positioned, any repositioning also requires major work, involving heavy equipment. There is therefore a need to make it possible to easily fix and reposition the measurement housings, with simplified implementation.\n\nThe invention provides various technical means for alleviating these various drawbacks.\n\nFirst of all, a first object of the invention is to provide a fixing system for a housing, for the simple and rapid measurement of tyre characteristics, to be installed in the ground.\n\nAnother object of the invention is to provide a fixing system for a housing for measuring tyre characteristics, the installation of which can be performed using standard tools.\n\nAnother object of the invention is to provide an economical and easily industrializable fixing system.\n\nAnother object of the invention is to provide a fixing system which does not disturb the operation of the measurement housing.",
