Definitions

  • the invention relates to the anchoring, in the ground, of poles or stakes, by means of a dowel having a rigid part, advantageously composed of metal plates shaped into fins, said rigid part forming a sheath intended to receive, once the dowel is sunk into the ground, the base of the post or stake.
  • this tool allows you to push the dowel well into the ground, without deforming it and without letting the earth penetrate its sheath.
  • the invention relates to a tool of the aforementioned type, which offers a particularly high impact resistance and also allows easy replacement of the most fragile elements in the event of wear or breakage.
  • the central part of said elongated body comprises: an upper portion of larger section capped by a bell-shaped part provided with a central passage for the upper part of the elongated body and whose upper surface forms said striking surface; and a lower portion whose section has a dimension equal to the circle inscribed in the horizontal section of the ankle sleeve, said lower portion being surrounded by a flat piece whose lower surface constitutes said bearing surface and whose upper surface is connected to the base of said bell.
  • the lower part or pin of said elongated body comprises a lower end portion whose section has a dimension substantially equal to that of the ankle sheath and having a pointed end and an upper portion connected to said lower portion of the central part and of reduced section.
  • the whole of said elongated body including its upper part or handle, its central part with its two different sections corresponding to two distinct cylindrical portions or to a single frustoconical portion, and its lower part, provided a portion of reduced section and a pointed end portion or "plug", consists of a single piece, advantageously by foundry or forging, while the striking bell and the flat support piece are patches.
  • the handles of the ram have a lower end secured to the body of the sleeve, preferably by a long longitudinal weld, while their upper curved end freely penetrates into a longitudinal channel which opens to the surface d the upper end of the sleeve and has a depth greater than the length of the handle portion which penetrates therein.
  • the elongated body of the tool constituted, in the preferred embodiment described, in a single piece of foundry, a process which allows a body to be produced inexpensively in which the longitudinal fibers metal (steel for example) are preserved and thus offer a great resistance to tearing, includes: a cylindrical handle 1, having for example 30 mm in diameter and 900 mm long; a central part 2, composed of a cylindrical upper portion 20 having for example 50 mm in diameter and a cylindrical lower portion 21 having 50 mm in height and for example 35 mm in diameter, which corresponds substantially to the dimension of the circle most commonly used ankle scabbard entry; and a spindle 3, composed of a pointed bottom plug 32 having a height of 190 mm and a section of the same section as the ankle sheaths and of an upper portion 31, 260 mm in height and of reduced diameter equal to 28 mm in the example considered.
  • the upper portion 20 of the central part is capped with a bell 4 having for example an outer diameter of 80 mm and a height of 65 mm and fitting exactly on said upper portion 20, a central passage 41 allowing the crossing of its upper striking surface 42 by the handle 1.
  • the bell rests at its base on the upper surface of a flat piece 5, 30 mm thick provided with a central circular preservation recess 51 having for example 60 mm diameter, and through which the portion 21 passes coaxially.
  • the lower surface 52 of the flat part 5 serves as a bearing surface and its largest dimension is for example equal to 250 mm.
  • this bearing surface is not circular, but comprises for example one of the forms lightened by recesses 57, 58 illustrated by FIGS. 4 and 5, where it can also be seen that the bearing part 5 is provided with reinforcing fins, such as 53 to 56, integral with the striking bell 4, while the bearing surface is provided with one or more longitudinal notches, such as 59, which facilitate the positioning on the ankle fins.
  • the shape of the bearing surface will be adapted to the geometric configuration of the set of fins.
  • the central protruding part 2 has significant mechanical strength and makes it possible to constitute, on the one hand a fitting element 20 for the striking bell 4, on the other hand, a portion 21 which cooperates with the plug 32 for ensure the relative guiding of the dowel and the false stake.
  • the use of the striking bell makes it possible to increase the section of the striking surface with which the base of the ram cooperates, without thereby excessively increasing the section of the body of the tool, which must be as light as possible.
  • the plug 32 has, over its entire height, with the exception of the pointed part, a section such that it conforms perfectly to that of the ankle sheath, to within a few tenths of a mm, and lubrication is recommended to facilitate removal of the tool at the end of the driving operation.
  • the very small thickness of the clearance prevents the penetration of the earth during sinking.
  • the intermediate reduced section 31 reduces the risk of the false stake sticking to the sheath.
  • the support piece 5, the bell 4 and even the central guide portion 21 and the plug 32 can be removably mounted (by screwing, or fitting) so as to be changed in the event of wear or breakage, or again, as regards the plug and the central guide portion, with a view to using the same tool for dowels having sheaths of different sections.
  • the central part 2 it is possible to give the central part 2 the shape of a truncated cone whose upper base will have a diameter of 50 mm for example and the lower base, a diameter of 35 mm.
  • the section of this central part will then have no discontinuity and its lower base will also be connected without section discontinuity with a frustoconical upper part of the spindle 3.
  • the flat part 5 will not, in this variant, have a central recess such as 51 figure 1, but will be directly fitted on the central part 2.
  • the frustoconical central part 2 by engaging at the start in the sheath of the ankle, will wedge the latter and, from the first shocks of the ram, the ankle will be flared by going up along the frustoconical central part 2, which will facilitate the introduction of the post at the end of the operation. No risk of crimping the ankle sheath exists.
  • the ram has a cylindrical sleeve 6 having for example 600 mm long, an outside diameter of 80 mm (equal to that of the striking surface 42) and an inside diameter of 31 mm (therefore , slightly higher than that of handle 1 on which it slides).
  • the relatively large height and the relatively small section of the ram give better sliding guidance with a greater stroke, and a very centered impact on the striking surface.
  • four handles 7, 8, 9, 10 are provided, arranged with a uniform distribution at the periphery of the sleeve 6 and secured to the latter at only one of their ends. Indeed, it was found that the joining of the handle at its two ends would cause rigidity such that shock waves would break the junctions after a certain operating time.
  • the attachment of the handle is made at its lower part, by a longitudinal weld 71, which offers a very high resistance to tearing by the shock wave which arises nearby.
  • the upper part of the handles is left free, which allows the dissipation of the shock wave; to avoid, however, secondary parasitic vibrations and deformations, this upper part is curved at a level higher than that of the upper end of the sleeve and its end descends to penetrate with a very small clearance in a channel 72 formed in the body of the sleeve annular and opening to the transverse outer surface thereof.
  • a gap 73 is provided between the end surface of the handle and the bottom of the channel.
  • the tool of the invention cannot be used exclusively with the dowel described in the above-mentioned certificate of addition and patent, although it has been more particularly designed to adapt to it.
