     2. Description of the Prior Art 
     The search for means for anchoring objects to the ground, such as for the firm holding of temporary transportable shelters, is a constant preoccupation. A review of the prior art has revealed the following patents: 
     U.S. Pat. No. 425,385 McKay, W. W. April 1890. This patent describes an anchoring device comprising a ring forming a large circumferential band, pierced by two holes at 30° from a vertical diametral axis; the holes making a V with a third hole placed opposite to the other two. Rods are inserted in these two holes, to make two angular poles. The ring is used to secure a rope, the tension of which putting pressure onto the rods, thus preventing their removal. 
     GB 0,022,461 Gartland et al, October 1909. This patent shows an anchoring device comprising a ring that has two holes at 30°, diametrically opposed to two other holes pierced in the ring wall and forming an X with the first two holes. Rods are diagonally inserted in these holes to form angular poles. A third vertical rod fixes the ring into the ground. This invention has an application where one of the rods has a bulge that keeps it inside the ring and makes the third rod useless because the captive rod can be driven into the ground. This device is not easily padlocked. 
     U.S. Pat. No. 4,063,567 Martin et al, 20 Dec. 1977. This patent illustrates a ground anchoring device that prevent tents exposed to strong winds to collapse. It is made of an elongated rod, with a curved section FIG. 4a, on which a hook can be attached on the superior part, and that is diagonally driven into the ground and held in place by a nail driven into the ground perpendicularly to the rod. This device cannot be easily dismantled and cannot be padlocked.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The preferred embodiment of the invention is illustrated in FIG. 1 where the same characterizing elements are identified by the same numbers. 
     The device illustrated in FIG. 1 comprises two metallic rods, a first rod 20 angularly oriented from left to right, from top to bottom, and a second rod 22 oriented from right to left, from top to bottom. The first rod 20 is covered with asperities and comprises a flat part 26, at a superior end 28, and a point 30 at an inferior end 32. The second rod 22 is similar to the first rod 20, but for a safety catch 34 (FIG. 4) placed above the point 30 1  of the inferior end 32 1  of the second rod 22. The superior end 28 of both rods is obstructed by a weld 36 of a metallic disc 38 slightly sunken, to which is welded a first metallic eyelet 40 of the first rod 20, the first metallic eyelet 40 resulting from the twisting of a metallic bow 39 originally placed in the same direction as the metallic disc 38. For the first rod 20, the first metallic eyelet 40 results from the twisting of the bow counterclockwise, while for the second rod 22, a second metallic eyelet 41 results from the twisting of the bow clockwise. Two tubes, of a diameter superior to the one of the rods, a First tube 42, positioned from left to right and facing the user and a second tube 44, positioned from right to left, welded together in a cross-shaped form 45 (FIG. 5) are used as a restraining sleeve 48 for the two rods. The first rod 20, inserted in the first tube 42, remains detachable while the second rod 22, inserted in the second tube 44 is blocked by the safety catch 34. 
     FIG. 2 illustrates the restraining sleeve 48 of the superior end 28 of the first and second rods 20 and 22, the first and second metallic eyelets 40 and 41, positioned in an opposed and parallel direction, so the first metallic eyelet 40 of the rod 20 superposed itself on the second metallic eyelet 41 of the second rod 22 to create a single eyelet 47 (FIG. 3) that can be tied with a padlock 49 (FIG. 3), tying the first rod 20 to the second rod 22 at their superior ends 28 and 28&#39;. 
     A variant of this embodiment comprises an adapter 52 illustrated in FIG. 6. This adapter 52 shown in perspective (FIG. 7) is an L-shaped angle iron of which a perforated left side 54 comprises two holes 56 placed equidistantly on a median line and of which a right side 58 has an assembly tube 60 fixed by a sleeve weld 61 on its centre and positioned diagonally from left to right, from top to bottom. Another embodiment has the tubes located within a monolithic block 62 comprising two diagonal apertures, placed perpendicularly and in superimposed planes. This monolithic block 62 may comprise means for tying to a structure to fix in position. Two curved rods 64 with formed eyelets 66 a their extremities, comprise a percussion disk 68 and a collar closed at the junction between the rod and the eyelet. 
     METHOD OF UTILIZATION 
     This portable anchoring device may be used with or without the adapter 52. Without it (FIG. 1) the method for using the device comprises these steps: 
     place the restraining sleeve 48 with the first tube 42 free, facing the user; 
     slide the restraining sleeve 48 until achieving an X-shaped position, the inferior end 32 1  of the second rod 22 positioned below and to the left of the user; 
     retract the second rod 22 inserted in the second tube 44 until the safety catch 34 is in contact with the tube 44; 
     press the inferior end 32 1  of the second rod 22 against the ground, at this time the second rod 22 will have a 45° axis with the ground. 
     drive the second rod 22 into the; ground, according to the angle defined by the second tube 44 of the restraining sleeve 48, with the assistance of a hammering tool acting upon the flat disk 26&#39;, 
     insert the first removable rod 20 into the first tube 42 free and drive it into the ground, as for the second rod 22, according to the angle defined by the first tube 42 of the restraining sleeve 48, hammering onto the flat disk 26; 
     press the rods into the ground, until the superior ends 28 and 28 1  are at the level of the restraining sleeve 48; 
     turn the first and second metallic eyelets 40 and 41 of the first and second rods 20 and 22 and place them so the first eyelet 40 of the first rod 20, facing the user, covers the second eyelet 41 of the second rod 22 (FIGS. 2-3), 
     padlock the first and second metallic eyelets 40 and 41. 
     In case where the material is likely to offer resistance when turning the rods 20 and 22 when totally driven into the ground, the user should see that the eyelets 40 and 41 are in an appropriate position before driving in the rod completely into the ground. 
     When using the adapter 52 (FIG. 6), the method varies according to the orientation of the adapter 52; for instance when in superior horizontal position (FIG. 8A) and when in inferior horizontal position (FIG. 8B), the second tube 44 of the restraining sleeve 48 will be sled in the assembly tube 60 from right to left, consequently the first rod 20 will slide in the first tube 42 from left to right. On the other hand, in left position (FIG. 8C) and in vertical right position (FIG. 8D), the second tube 44 of the restraining sleeve 48 will be inserted into the assembly tube 60 from left to right and consequently the first rod 20 will be inserted in the first tube 42 from right to left 
     So when the adapter 52 (FIG. 1) is used, the utilization mode comprises the following steps: 
     put the adapter 52 onto a tridimensional object, in a plane either horizontally superior FIG. 8A, horizontally inferior FIG. 8B, vertically left FIG. 8C or vertically right FIG. 8D and secure it with bolts in the holes 56. When in horizontally superior position the assembly tube is in position at 225° anticlockwise to the junction line of the two parts of the angle iron, in horizontally inferior position the angle being 45°, in vertical left position, the angle being -45° and in a vertically right position the angle being of 135°; 
     place the first tube 42 facing the user to direct the first rod at the required angle to circumvent obstacles; 
     retract the second rod 22 inserted in the second tube 44 until the safety catch 34 is in contact with the tube 44; 
     press the inferior end 32 1  of the second rod 22 against the ground, at this time the second rod 22 will have its longitudinal axis at 45° with the ground; 
     drive the second rod 22 into the ground, according to the angle defined by the second tube 44 of the restraining sleeve 48, with the assistance of a hammering tool against the flat disk 26 1  ; 
     insert the first removable rod 20 into the other tube 42 and drive it into the ground, as for the second rod 22, according to the angle defined by the first tube 42 of the restraining sleeve 48, while hammering onto the flat disk 26; 
     press the rods into the ground, until the superior ends 28 and 28 1  are at the level of the restraining sleeve 48; 
     turn the first and second metallic eyelets 40 and 41 of the first and second rods 20 and 22 and place them so the first eyelet 40 of the first rod 20 facing the user, covers the second eyelet 41 of the second rod 22; 
     padlock the first and second metallic eyelets 40 and 41.
