Definitions

  • the invention relates to improvements to stakes. support for nets and snow probes.
  • nets like, for example, nets for marking of tracks or nets for the protection of skiers or wind protection nets; these nets are supported by stakes whose main body consists of a cylindrical rod of revolution which are driven into the ground by a lower end having a point and which have at the upper end a impact head for driving in the support post nets and one or more rings to hang the nets.
  • net support posts are designed to have good rigidity to resist stress of environment linked, in particular, to the efforts supported by the nets like, for example, the impact of a skier, the effort exerted by a strong wind, or the weight of snow; they have safety points at the attachment points to limit the level of effort applied to post, in order to keep its integrity, such as collars that may slide along the stake support for broken nets or rings liable to open if the effort is too great.
  • These posts of a length of the order of one and a half to two meters are generally cylindrical with a diameter of the order of twenty millimeters, are made from extruded tubes aluminum and are fitted with an added point comprising its base a cylindrical part, of a diameter substantially equal to the inside diameter of the tube and separated from the tip by a shoulder having substantially the outside diameter of the tube; this point is designed so that the support post nets could be torn off in the event of abnormal efforts to avoid its destruction.
  • poles of sounding of which the main body of the pole is a rod made, either from a tube with a diameter of about twelve millimeters in one piece, either from segments aluminum tubes of the same diameter, the ends of which have male and female threaded parts that allow their end-to-end assembly; survey poles have a kind of half-ball at their lower end terminated by a cylindrical base, with a diameter substantially equal to the inside diameter of the aluminum tube, which enters the tube with a shoulder of a diameter equal to the outside diameter of the tube.
  • the invention consists in improving the performance of net stakes and survey poles in separating the functions at first for the intrinsically improve and then harmonize them between they.
  • the main body of the stakes and poles is made up by a cylindrical rod of revolution composed of wires of glass in one piece over the entire length of the stem, coated with polycondensable polyester resin.
  • the invention consists in replacing the main body of stake 1 (fig. 1 and 2) or the main pole body 2 (fig. 3 and 4), initially made of an aluminum tube, by a cylindrical rod of revolution obtained by pulltrusion, composed of glass threads in one piece on the entire length of the rod, which are preferably coated polycondensable polyester resin.
  • This rod is present in the form of either a thick-walled tube 3 (fig. 3) either rod 4 (fig.
  • the thick-walled tube 3 is used to preference for survey poles while rods 4 are preferably used to make the stakes net holders;
  • the cylindrical rod used has a outer diameter which is of the order of fifteen to twenty millimeters and when formed from a wall tube thick 3, the wall thickness is around fifteen to twenty percent of the outside diameter of the thick walled tube 3.
  • a tip 8 which is generally conical and which is at its base larger in diameter than the main stake body 1; it is extended by a lower cylindrical sleeve 9 of revolution of a length of the order of two to five centimeters and whose internal diameter is adjusted to outside diameter of the main stake body 1; the body main stake 1 is fixed in the cylindrical sleeve lower 9 by gluing, which can be for example of the polyurethane glue and a lock can ensure assembly; it can be made with a pin 10 crossing diametrically the entire main body of stake 1 and the lower cylindrical sleeve 9.
  • the diameter of the lower cylindrical sleeve 9 being greater than that of the main body of stake 1, it acts as a restraint in the ground at the point 8 while the main body the stake itself has in its buried part a certain degree of freedom which is favorable to his ability to elastic deformation.
  • the upper end of the stake 11 is simplified compared to that of the net support stake aluminum and in particular it is no longer essential use necklaces that could slide along the main body of the net support post as well as broken rings since it is the main body that absorbs the efforts ; as a result the upper end of stake 11 consists of a striking head 12 of a diameter greater than the diameter of the main stake body 1 connected by an intermediate cylindrical part 13 to a cylindrical upper sleeve 14 of revolution of a length of the order of two to five centimeters and whose diameter interior is adjusted to the diameter of the main stake body 1; the main stake body 1 is fixed in the sleeve upper cylindrical 14 by gluing, which can be, by example, polyurethane glue and a lock can ensure assembly; it can be made by a pin 15 crossing diametrically the entire main body of stake 1 and upper cylindrical sleeve 14; rings attachment nets are attached to ear cups 16 (fig.
  • the aluminum parts placed at lower 7 and upper 11 ends can be mainly made of cast aluminum.
  • they are preferably consisting of a main pole body 2 consisting of a thick-walled tube 3 (fig.
  • a first lower end pole 19 has a tip formed of a first face rounded 20 convex, connected to a first lateral surface 21 in the shape of a cylinder of revolution of low height and diameter slightly greater than the diameter of the main body perch 2 which can be of the order of one to two millimeters; the latter is itself connected to a second rounded surface 22 oriented in opposition by relative to the first rounded face 20; these three surfaces 20, 21 and 22 having a common axis of symmetry 23; the second rounded surface 22 has in its central part a first cylindrical rod 24 of revolution of a few centimeters long and of diameter substantially equal to inner diameter of the thick-walled tube 3; the first one cylindrical rod 24 is connected to a first shoulder annular 25 whose outside diameter is the diameter outside of the thick-walled tube 3.
  • the first rod cylindrical 24 is used to fix the first end lower pole 19 in the main body of pole 2; it is inserted into the end of the thick-walled tube 3 and it is glued to it by an adhesive which can be an adhesive polyurethane; in a variant of the invention, the first cylindrical rod 24 has at regular intervals annular grooves 26 which facilitate fixing by gluing of the first cylindrical rod 24 ensuring better glue distribution; in another variant of the invention, the assembly is locked by a pin crossing the lower end of the main body of pole 2 and the first cylindrical rod 24.
  • the shape of the first lower end of pole 19 makes it possible to produce a hole wider than the diameter of the main body of pole 2 which facilitates the sliding of the pole survey 6 on insertion and withdrawal;
  • the second surface rounded 22 has, at its junction with the body main pole 2, a ramp which allows, when removing sounding pole 6 from its hole, regular evacuation snow.
  • a second lower end of pole 27 (fig. 4) is formed of two elements similar to the one just described which are placed in series on the same axis of revolution: the second lower end of pole 27 has a third rounded surface 28 convex, similar in shape to that of the first rounded convex surface 20, limited externally as before by a second surface lateral 29 cylindrical of revolution of low height of a diameter preferably identical to the diameter of the first lateral surface 21; this lateral surface 29 limits externally a fourth convex rounded surface 30, which is in opposition to the third rounded surface 28, which is connected internally on a third surface lateral 31 cylindrical low height with a diameter substantially equal to the inside diameter of the main body of pole 2; the other end of the third side surface 31 internally limits a fifth rounded surface 32 convex externally bounded by a fourth surface lateral 33 cylindrical of revolution of low height and slightly larger in diameter than the second lateral surface 29; finally a sixth rounded surface 34 con
  • the link between the segments is made as for the aluminum survey poles with male and female end caps screwed together.
  • the main body of pole 6 has a diameter of fifteen millimeters
  • the second lateral surface 29 has a diameter of fifteen millimeters
  • the fourth lateral surface 33 has a diameter of sixteen millimeters.
  • the description relates to the use of glass fibers for the production of rods and tubes thick wall intended to make stakes and poles survey; it is obvious that glass threads can be replaced by all synthetic yarns of mineral origin or organic such as carbon fiber whose amplitude of the area of elastic deformation by stretching is substantially that of the glass strands so the levels corresponding effort.
  • glass threads can be replaced by all synthetic yarns of mineral origin or organic such as carbon fiber whose amplitude of the area of elastic deformation by stretching is substantially that of the glass strands so the levels corresponding effort.
