Definitions

  • the present invention relates to telescopic tubular assemblies, such as, for example but not limited to, the poles used for ski touring or mountaineering, comprising several successive tubular sections and sliding in each other between a retracted position and a position deployed.
  • These telescopic poles are used to adjust the length of the pole according to the slope of the terrain on which the user is moving.
  • the stick is intended to support an axial force. Consequently, selective locking means must allow the sections to be axially blocked in relation to the others, either in the deployed position, in the retracted position, or in all intermediate positions.
  • an axial end piece is fixed as an extension of a first tubular section of small diameter.
  • the nozzle generally has a conical bearing and a threaded part.
  • An expandable locking ring is mounted to slide axially in the tubular section of large diameter, and has a generally conical inner bearing bearing against the conical bearing of the axial end piece.
  • An actuator means such as a nut is adapted to slide axially in the tubular section of large diameter and be locked in rotation in this tubular section, the actuator means screwing onto the threaded part of the axial end piece to axially tighten and loosen the ring by relative rotation of the tubular sections.
  • the actuator means is constituted by the locking ring itself, which rubs against the inner wall of the large diameter tube.
  • the blocking in rotation of the ring turns out to be random.
  • the actuator means also consists of the ring itself, which is locked in rotation in the large diameter tube by a longitudinal rib projecting from the inside of the tube and coming lodge in a longitudinal groove in the ring.
  • the inner rib of the large-diameter tube constitutes a hindrance in guiding and sliding the small diameter tube inside the large diameter tube. There is then poor guidance between the two tubes, which are not concentric. During bending efforts on the stick, the inner rib deforms the tube of small diameter and deteriorates it.
  • the actuating means is also the locking ring itself, which can slide in the large diameter tube and is locked in rotation in this tube by two diametrically opposed ribs in the ring and fitting into two grooves in the inside of the large diameter tube.
  • Outer ribs protrude from the outer surface of the large diameter tube, in correspondence with the inner grooves.
  • Such an arrangement may be suitable for a stick having only two sections.
  • the outer ribs of the large diameter tube would prevent the adaptation and correct maintenance of a third tube over this large diameter tube.
  • Document US-A-4 238 164 describes a two-tube structure, in which the actuating means is the locking ring, which can slide in the large-diameter tube and is locked in rotation in this tube by three convex internal ribs of the large diameter tube engaged in three concave longitudinal grooves of the ring.
  • the small diameter tube is a smooth cylinder of revolution.
  • the problem proposed by the present invention is to design a new locking structure which ensures both good guidance of the tubes relative to each other, without subjecting the locking ring to undue mechanical stress, the structure being further compatible with the presence of three or more of three successive tubes.
  • the inner ribs of the larger diameter tube, forming grooves therefore constitute both means for blocking the rotation of the first actuator element, and suitable means for guiding and holding the smaller diameter tube during sliding in the larger diameter tube.
  • the fluted tubular structure thus obtained is particularly rigid, without any increase in weight.
  • the telescopic tubular assembly according to the present invention is a stick comprising three successive sections, namely a first tubular section 1 of larger diameter, a second tubular section 2 of smaller diameter, and a third tubular section 3 of even smaller diameter.
  • the second section 2 is slidably mounted in the first section 1.
  • the third section 3 is slidably mounted in the second section 2.
  • a portion of the second section 2 remains permanently inside the first section 1, and it includes a inner end 4.
  • the first tubular section 1 of larger diameter has a cylindrical inner surface 5 of generally circular section, comprising at least three longitudinal ribs 6, 13 and 14 occupying all or most of its length, and of low height.
  • the second tubular section 2 of smaller diameter has a cylindrical outer surface 60, of generally circular section, shaped to slide axially in the interior space limited by the interior surface 5 and the longitudinal ribs 6, 13 and 14 of the first section tubular 1 of large diameter.
  • the inner surface 5 of the first tubular section 1 has three longitudinal ribs 6, 13 and 14 regularly distributed around the periphery of the section.
  • the three longitudinal ribs 6, 13 and 14 engage in three respective corresponding grooves 15, 16 and 17 of the locking ring 10.
  • the ribs 6, 13 and 14 are formed by driving in the wall of the tube forming the first tubular section 1, the depression simultaneously producing the longitudinal external grooves 18, 19 and 20.
  • the longitudinal external grooves 18, 19 and 20 have a width slightly smaller than the corresponding internal ribs 6, 13 and 14.
  • the ribs 6, 13 and 14 must form the bearing surface on which the inner tubular section slides or pivots 2. This bearing surface must be able to withstand the mechanical stresses bending that you want to apply between two successive sections of a telescopic stick. For this, as shown in the figures, the ribs 6, 13 and 14 have a wide and rounded ridge surface, to match a significant part of the periphery of the outer surface of the second tubular section. The ribs 6, 13 and 14 are shaped to come into abutment with little play and simultaneously against the external surface of the second tubular section 2.
  • the second tubular section 2 also includes ribs and grooves similar to those of the first tubular section.
  • its outer grooves 21, 22 and 23 are narrower than the inner ribs 6, 13 and 14 of the first tubular section 1.
  • the inner ribs 6 , 13 and 14 of the first tubular section cannot engage in the corresponding external grooves 21, 22 and 23 of the second tubular section, which can thus freely pivot axially in the first tubular section 1.
  • the second tubular section 2 carries, as an extension of its internal end 4, an axial end piece 7 having a generally conical surface 8 extended by a threaded part 9, for example of smaller diameter .
  • a threaded locking ring 10 is screwed onto the threaded part 9 of the axial end piece 7, and it comprises a generally cylindrical outer surface 11 shaped to slide axially with little play in the first tubular section 1 and to be locked in rotation by the inner ribs 6, 13 and 14 of the first tubular section 1.
  • the locking ring 10 comprises an end zone 12 which is elastically deformable in the radial direction, and oriented axially so as to bear on the conical bearing 8.
  • the locking ring 10 comprises a central bore 37 threaded, to cooperate with the threading of the threaded part 9, and a first generally conical bearing 39 to cooperate with the conical bearing 8.
  • the length of the locking ring 10 is slightly less than the length of the threaded part 9.
  • the free end 24 of the threaded part 9 comprises an enlarged part, of diameter greater than the diameter inside of the locking ring 10 to form a stop limiting the stroke of the ring away from the conical bearing 8.
  • the locking ring 10 comprises, in its end region 12, longitudinal slots such as the slot 25, to increase the flexibility of this end region. Radial deformations of the end zone 12 are thus favored by the effect of the conical bearing 8 at the end of the screwing of the locking ring 10 on the threaded part 9.
  • the ring 10 constitutes the expandable element and the first actuator element, while the end piece 7 constitutes the second actuator element.
  • the endpiece 7 is an attached endpiece, forcibly engaged in the interior end 4 of the second tubular section 2.
  • a sealing ring 26 is fitted on the covering end 27 of the first tubular section 1, to which it is secured axially.
  • the sealing ring 26 comprises an inner rim 28 which engages in an external annular groove 29 of the first tubular section 1.
  • the end face 30 of the sealing ring 26 comprises an opening 31, the opening of which section corresponds to the outside section of the second tubular section 2, so as to slide with little play on the outside surface of the second tubular section 2.
  • a stop limits the movement of the locking ring 10 to the deployed position of the stick.
  • the stop is produced by a groove 32 or a punching on the surface of the first tubular section 1, producing a lug protruding from the interior face of the first tubular section 1 and against which the end region 12 of the ring comes to bear. lock 10.
  • FIGS. 1 and 2 Another embodiment of abutment is shown in FIGS. 1 and 2, in the form of one or more tongues 33, integral with the sealing ring 26, and coming to be housed in the space formed by the outer groove 22 of the second tubular section 2.
  • the tongue 33 comes to bear, at the end of its travel, against the end region 12 of the locking ring 10.
  • a similar locking structure is provided, as shown in FIG. 2, between the second tubular section 2 and the third tubular section 3.
  • the operation of the device is as follows: in the position shown in FIG. 1, the locking ring 10 is away from the conical bearing 8. In this position, the locking ring 10 slides freely, without significant friction, in the first tubular section 1. As a result, the second tubular section 2, which is axially integral with the locking ring 10 and the end piece 7, slides freely in the first tubular section 1. To obtain the locking of the successive sections the relative to each other, when the desired length of the stick has been obtained by axial sliding, the user causes a relative rotation of the second tubular section 2 in the first tubular section 1. During the rotation of the second tubular section 2, the ring locking 10 remains integral in rotation with the first tubular section 1, and is therefore screwed onto the threaded part 9, when the rotation is in the direction of screwing.
  • the locking ring 10 comes to bear against the conical bearing 8, which causes the flaring of the end zone 12.
  • This end zone 12 comes to bear against the internal surface 5 of the first tubular section 1 , ensuring high friction preventing any subsequent axial sliding of the tubular sections into one another.
  • a similar locking is obtained by relative rotation of the third tubular section 3 in the second tubular section 2.
  • the sliding of the successive sections into one another is limited, in the direction of the separation of the sections from one another, by the stops such as the groove 32 or the tongue 33 coming to bear against the end zone 12 of the locking ring 10.
  • the expandable member is a locking ring 10.
  • the actuator member comprises a first actuator element consisting of a nut 35 which is screwed onto the threaded part 9 of the axial end piece 7 forming the second actuator element.
  • the nut 35 is shaped to slide axially in an axial passage 36 of the ring 10 while being locked in rotation relative to said ring 10.

  • the conical surfaces 39 and 40 of the ring 10 are arranged substantially at one third and two thirds of the length of the ring. This results in a significant increase in the area of friction of the ring on the internal face of the first tubular section 1.
  • Figures 13 to 18 illustrate six embodiments, shown schematically in longitudinal section, only the elements involved in the locking being shown.
  • the expandable element is a locking ring 10, generally cylindrical, provided with an axial bore.
