Definitions

• the invention relates to anchoring in the ground, more particularly, but not exclusively, of fence posts or stakes.
• an ankle In the first addition to French patent n ° 79 09679 filed on April 10, 1979 by the Applicant for: Anchor intended for the fixing in the ground of posts or stakes and devices serving for the insertion of this ankle ", an ankle has been described constituted by two portions of profiled metal plates, preferably in a zig-zag, each forming a shaped fin to facilitate its vertical penetration into the ground and offer, once pressed, a transverse resistance, said fin having a folded edge so as to constitute a prismatic sheath open along an edge, these two sheaths being fitted one into the other to form a central prismatic sheath prevailing over the entire height of the ankle.
• Such an anchor provides effective anchoring of a pole which is simply inserted into the sheath, without needing to be sealed. It is easy to install and sufficiently rigid, even when made of thin sheet metal.
• the subject of the present invention is a method of manufacturing dowels of the aforementioned kind, capable of reducing machining operations and metal scrap, of authorizing continuous manufacture from a strip and of authorizing the production of shapes. varied adapted to all needs.
• the method according to the invention is mainly characterized in that the aforementioned sheath is obtained by profiling the two edges of a strip intended for the formation of several dowels, while each of the fins is obtained by cutting, on the one hand perpendicular to the generating sleeves to form sections of profiled strip each having a length corresponding to the height of the ankle and on the other hand, for each section, along a diagonal plane.
• each section provides two fins, optionally folded or centered during the edge profiling operation, the sheaths of which advantageously have only a slot intended to allow the interlocking of the two sheaths of two fins.
• which will preferably be assembled together by sliding one into the other of their respective sleeves, will be cut at a bevel at one end and, without additional machining, shaped into a point suitable for penetration, the scrap of metal corresponding being very small and falling by itself during diagonal cutting.
• FIG. 1 is a diagram of the sections of profiled and cut strip intended to illustrate the method of the invention
• FIG. 2 represents the assembly of half-sections of strip to form a dowel
• Figure 3 is a side view of an ankle sheath obtained by interlocking the two sleeves of the respective half-sections.
• Figures 4 and 5 show in end view two different assemblies of the same half-sections asymmetrical folding.
• the method of the invention in a first embodiment, consists in establishing, from a very long strip, for example of sheet metal, a continuous profile, by means of a press, by folding the edges of the strip to form sheaths 1 and 2 and, optionally, by folding or bending the portion of intermediate strip 3, and to proceed, also continuously, to cutting said profile into sections A 1 B 1 , A 2 B 2 , and by means of cutouts which will be successively perpendicular to the generatrices of the sleeves and diagonals, that is to say going from a section angle such as A 1 B 1 to the opposite corner of this section.
• each anchor to assemble two half-struts by presenting, as shown in FIG. 2 , the half-section A 1 behind the half-section B 1 , the latter having retained the portion illustrated in FIG. 1, while A 1 has been turned over so that the tip 22 of its sheath comes to engage in the slot of the sheath B 1 , at the straight-cut end of the latter sheath: we see that thus two of the faces of the sheath A, engage inside the sheath B 1 , while the third face of the sheath of A 1 , which is extended by the fin, remains outside the sheath of B 1 .
• the position is shown in dotted lines in FIG. 2. final of A 1 in the finished ankle.
• the two oblique points of the sheaths of A 1 and B 1 obviously facilitate the penetration of the ankle into the ground. No welding is necessary to make the dowel.
• the central sheath obtained by interlocking the two sleeves has a double thickness of metal on its three faces, which improves its rigidity.
• a wide variety of shapes can be obtained, as required.
• the profiled strip could, instead of being metallic, be made of plastic, certain known forming techniques include for example both the exercise of a traction and a push on the profile during forming, allowing to produce semi-closed profiled edges on such a strip.
