[0098] FIGS. 1 to 4 show a securing device 10 comprising a securing pin 11. In at least one embodiment described herein, the securing device 10 comprises an erosion control securing pin for securing an article in the form of geotextile matting 100 (see FIGS. 3 and 4) to the ground 101 to reduce erosion of the ground 101. However, it will be appreciated by the skilled person that the securing device 10 could be used to secure other products to the ground, for example, fences, other geotextile materials or geotextile articles, or indicating devices

[0099] The securing device 10 is formed as one piece and comprises an elongate member 12 comprising a main shaft portion 14 having distal and proximal ends 16, 18. The securing device 10 further includes a securing portion 20 formed at the distal end 16 of the main shaft portion 14. An engaging portion 22 and a mounting member 24 are formed at the proximal end 18 of the main shaft portion 14.

[0100] The securing portion 20 is substantially helical to allow the securing device 10 to be screwed into the ground. The securing portion 20 defines a central space 20A (see FIG. 7) around which the securing portion 20 extends. The securing portion 20 extends radially outwardly from the main shaft portion 14. The securing portion 20 and the main shaft portion 14 are coaxial with each other.

[0101] The securing portion 20 extends a minor proportion of the length of the elongate member 12. In the embodiment shown, the length of the securing portion 20 along the elongate member 12 is about 20% of the length of the elongate member 12. This provides an advantage in the embodiment described herein that any attempt to remove the securing device 10, by simply pulling it out of the ground, will create an upward force from the securing portion 20 against a frustum of soil above the securing portion 20, thereby requiring a greater force to remove the securing device 10 than prior art pins.

[0102] Referring to FIGS. 3 and 4, the securing device 10 is shown in use with a region of the matting 100. It will be appreciated by those skilled in the art that the region of the matting 100 shown in FIGS. 3 and 4 is only a small part of the matting 100, and that it extends over a much larger area of the ground 101. The ground 101 is represented by a broken line in FIG. 4, so that the elongate member 12 can be seen.

[0103] The engaging portion 22 at the proximal end 18 of the elongate member 12 engages the matting 100 when the securing device 10 has been driven a sufficient distance into the ground 101. As the securing device 10 is driven into the ground 101, the engaging portion 22 urges the matting 100 against the ground 101, thereby securing the matting 100 to the ground 101.

[0104] As indicated above, the matting 100 extends over a much larger area than shown in FIGS. 3 and 4. In view of this, the use of a plurality of the securing pins 10 may be required.

[0105] Referring again to FIG. 2, a top view of the securing device 10 is shown, depicting the engaging portion 22 and the mounting member 24. The engaging portion 22 comprises a circular member 26 defining a further central space 26A. The mounting member 24 comprises a substantially straight attaching member 28 attaching the engaging portion 22 to the main shaft portion 14.

[0106] Referring to FIGS. 5 to 8, the mounting member 24 is provided to mount the securing device 10 on a drive arrangement comprising a drive transmission device 102 and a driving tool (not shown). The driving tool can be any suitable known hand operated drill.

[0107] The drive transmission device 102 comprises a receiving portion 104 for receiving the mounting member 24 of the securing device 10. The receiving portion 104 defines a rectangular recess 106, in which the mounting member 24 can be received. When the mounting member 24 is received in the recess 106, the receiving portion 104 is received by the engaging portion 22, as shown in FIGS. 7 and 8. This has the advantage, in the embodiments described herein, of stabilising the securing device 10 on the drive transmission device 102.

[0108] The drive transmission device 102 also includes a connecting member 108 for connecting the drive transmission device 102 to the driving tool. The connecting member 108 is substantially cylindrical and can be received by a standard chuck of a hand operated drill.

[0109] A frustoconical portion 110 extends between the connecting member 108 and the receiving portion 104.

[0110] In use, the drive transmission device 102 is connected to the hand operated drill in a manner that would be understood by those skilled in the art. The securing device 10 is mounted thereon by inserting the mounting member 24 into the recess 106 of the receiving portion 104, so that the receiving portion is received by, and extends through, the engaging portion 22.

[0111] While so mounted on the drive transmission device 102, the securing portion 20 is disposed against the matting to be secured to the ground. The user then operates the drill, thereby rotating the securing device 10 about the main shaft portion 14. By pressing down on the drill, the securing device 10 is screwed into the ground until the engaging portion 22 engages the matting 100. The driving tool can then further drive the securing device 10 to urge the matting 100 into tighter engagement with the ground 101, thereby securing the matting 100 to the ground 101.

[0112] FIGS. 9 to 20 show a further embodiment of a drive transmission device generally designated 202. The drive transmission device 202 comprises a receiving portion 204 for receiving the mounting member 24 of the securing device 10. The receiving portion 204 defines a generally ‘L’ shaped recess 206, in which the mounting member 24 can be received.

[0113] The recess 206 has a main region 206A, which is defined by a force transmission wall 208 and a second wall 210 opposite the force transmission wall 208. The main region 206A extends axially from an end opening 211A in an end face 212 of the receiving portion 204. The main region 206A of the recess 206 and the end opening 211 extend radially outwardly from a central region 214 of the receiving portion 204. The main region 206A also has an axially extending side opening 211B.

[0114] The recess 206 also has a support region 206B, which extends laterally from the main region 206A in a side of the receiving portion 204. The support region 206B of the recess 206 has a support formation in the form of a support surface 218 which extends from the second wall 210 transverse thereto. The support region 206B of the recess 206 extends radially inwardly from a laterally extending side opening 211C. The laterally extending side opening 211C extends laterally relative to the axially extending opening 211B.

[0115] FIGS. 13 to 15 show the mounting of the securing device 10 on the drive transmission device 202. The mounting member 24 is received in the support region 206B of the recess 206. When so received, the mounting member 24 engages the support surface 218 to be supported by the support surface 218. Thus, the securing device 10 can be carried by the drive transmission device 202 when the mounting member 24 is supported by the support surface 218.

[0116] When the mounting member 24 is received in the recess 206, the receiving portion 104 is received by the engaging portion 22, as shown in FIGS. 14 and 15. this provides the advantage, in the embodiments described herein, of stabilising the securing device 10 on the drive transmission device 202.

[0117] FIGS. 16A to 16B show the arrangement of the securing device 10 on the drive transmission device 202 and the driving of the securing device 10. In FIG. 16A, the drive transmission device 202 and the securing device 10 are shown separate from each other. FIG. 16B shows the drive transmission device 202 in engagement with the securing device 10 after the mounting member 24 has been received in the recess 206. In this position, the force transmission wall 208 is in engagement with the mounting member 24 and can thereby rotatably drive the securing device 10. FIG. 16C shows the rotation of the drive transmission device 202 in the direction indicated by the arrow A to drive the securing device 10 into the ground in the direction indicated by the arrow B.

[0118] The drive transmission device 202 also includes a connecting member 220 for connecting the drive transmission device 202 to the driving tool. The connecting member 220 is in the form of an elongate member which may be substantially cylindrical or have a hexagonal profile. The connecting member can be received by a chuck of a standard hand operated drill.

[0119] FIGS. 17 and 18 show a sleeve 219 provided around the receiving portion 204. The sleeve 219 defines an open end 221A through which the engaging portion 22 of the securing device 10 can be received. The sleeve has an opposite end 221B having a cover 223 extending across the receiving portion 204. The cover defines an aperture 225 through which the connecting member 220 extends.

[0120] Where the ground is hard, the rotational force applied by the drive transmission device 202 tends to uncoil the engaging portion 22, which has the effect of making it difficult to drive the securing device 10 into the ground. The sleeve 219 has the effect of holding the engaging portion 22 to prevent the engaging portion 22 from uncoiling.

[0121] FIGS. 19 and 20 show a modified version of the second embodiment of the drive transmission arrangement 202, in which the connecting member 220 is replaced by a long connecting member 220A to allow the user drive the to reach inaccessible places and to avoid continually bending down, and thereby providing health benefits to the user. FIG. 19 shows the drive transmission device 202 without the sleeve 219. FIG. 20 shows the drive transmission device 202 having the sleeve 219. In use, the drive transmission device 202 is connected by means of the connecting member 220 to a drill in a manner that would be understood by those skilled in the art. The securing device 10 is mounted thereon by inserting the mounting member 24 into the recess 206 of the receiving portion 204, so that the receiving portion is received by, and extends through, the engaging portion 22.

[0122] The mounting member 24 is positioned in the support region 206B of the recess 206 to be supported by the support surface 218. This allows the user to position the securing device 10 in the desired location simply by moving the drill tool as appropriate, and without any need for the securing 10 to be held in the user's hand.

[0123] While so mounted on the drive transmission device 202, the securing portion 20 is disposed against the matting to be secured to the ground. The user then operates the drill, thereby rotating the force transmission device 202 so that force transmission device 202 is in a driving position relative to the securing pin. In this position, the force applying wall 208 is moved into engagement with the mounting member 24.

[0124] Continued rotation of the force transmission device 202 rotates the securing device 10 about the main shaft portion 14. By pressing down on the drill, the user moves the drill towards the ground as the securing device 10 is screwed into the ground.

[0125] When the end face 212 of the drive transmission device 202 engages the matting, the continued rotation of the securing device 10 by the drill screws the securing device 10 further into the ground, which causes the mounting member 24 to move along the main region 206A and the engaging portion 22 to move along the receiving portion 204.

[0126] Continued rotation of the drive transmission device 202 by the drill moves the mounting member out of the recess 206 via the end opening 210. Thus, the embodiment shown in FIGS. 9 to 20 provides the advantage that the securing device 10 is driven into the ground until it tightly engages the matting and is released automatically form the drive transmission arrangement when such tight engagement occurs.

[0127] There is thus described a securing device 10 that can be used to secure geotextile matting 100 to ground 101 susceptible to erosion. The embodiment of the securing device 10 described herein provides the advantage that it is not easily removed from the ground 101, requiring a greater force than prior art securing pins to do so. In addition, the use of the embodiments of the drive transmission arrangements described above provide the advantage that the securing device 10 is driven into the ground until the engaging portion 22 is flush with the surface of the ground.

[0128] Various modifications can be made without departing from the scope of the invention.

[0129] FIG. 21 shows a securing device 250, which has all the features of the securing device 10 described above. A holding member, in the form of an axially extending member 252, is provided on the securing device 250. The axially extending member 252 is provided on the engaging portion 22 and extends alongside the shaft portion 14, substantially parallel therewith. The axially extending member 252 is formed integrally with the engaging portion 22 and thereby integrally with the securing device 250.

[0130] FIG. 22 shows the securing device 250 in use to secure a lower region 226 of fencing 228. The fencing 228 is supported by posts 220. The lower region 226 extends substantially flat along the ground. The fencing 228 is formed of wires 222 which extend in a grid formation.

[0131] In FIGS. 21 and 22, the securing devices 250 are driven into the ground so that some of the wires 222 are held between the axially extending member 252 and the shaft portion 14. In FIG. 21, one of the wires 222 is shown in broken lines.

[0132] FIGS. 23, 24 and 25 show the securing device 10 in use with a holding device, generally designated 312. The holding device 312 comprises a first portion in the form of a substantially circular cover portion 314 and a downwardly extending substantially cylindrical skirt portion 316 attached to the outer edge of the cover portion 314. The skirt portion 316 has a lower edge 318 defining a plurality of recesses 320. The cover portion 314 defines a central aperture 322 through which the shaft portion 14 of the securing device 10 extends in use.

[0133] As shown in FIG. 25, the holding device 312 can be arranged at a junction of two of the wires 222 forming part of the lower region 226 of the fencing 228, or along one of the wires 222. In each case, the holding device 312 is arranged so that the recesses 320 are disposed over the wires to avoid damaging them.

[0134] In order to install the securing device 10, the holding device 312 is first arranged over the respective wire or wires 222, as described above. The securing device 10 is then inserted through the aperture 322 by screwing the securing portion 20 through the aperture 322 and then into the ground beneath. The securing device 10 is then screwed into the ground until the engaging portion 22 engages the cover portion 314. The engagement of the engaging portion 22 with the cover portion 314 secures the holding device 312 onto the ground, thereby securing to the ground the wire or wires 222 received through the recesses 320.

[0135] FIGS. 26 and 27 show an indicating arrangement 330 comprising a securing device 10 and an indicating device 332 in the form of a boundary marker or a surveying marker. The securing device 10 secures the indicating device 332 to the ground.

[0136] The indicating device 332 is in the form of a cup having a base portion 334 defining an aperture 336 through which the shaft portion 14 extends. A substantially cylindrical projecting portion 338 is attached to the base portion 334. The securing device 10 can be screwed through the aperture 336 into the ground in the same way in which the securing device 10 is screwed through the aperture 322 as described above. The engaging portion 22 engages the base portion 334 and thereby secures the indicating device 332 to the ground.

[0137] When so secured, the projecting portion 338 projects from the ground to provide a suitable indicator for the user. The projection portion may be of a suitably high visibility colour.

[0138] FIGS. 28 to 33 show a securing device 10 and a holding device 340. FIGS. 28 to 30 show the holding device 340 in use in a first orientation. FIGS. 31 to 33 show the holding device 340 in use in a second orientation.

[0139] The holding device 340 is shown more clearly in FIG. 34 and comprises a substantially flat first portion 342. A pair of second portions 344 extend from the first portion 342. The second portions 344 extend from the first portion 342 in the same direction as each other, and are disposed at right angles to the first portion 342.

[0140] The first portion 342 is substantially flat and has a first formation in the form of a substantially ‘L’ shaped first slot 346 defined by the first portion 342. The first slot 346 extends inwardly of the first portion 342 from an edge 348 thereof. As explained below, the first slot 346 receives the shaft portion 14 of the securing device 10, so that the securing device 10 can extend through the first portion 342 to clamp the first portion 342 and, therefore the holding device 340, to the ground in either the first orientation or the second orientation.

[0141] Each second portion 344 is also substantially flat has a second formation in the form of a second slot 349 defined by the second portion 344. The second slot 349 extends inwardly of the second portion 344 from an edge 350 thereof. Each second slot 349 extends upwardly (as viewed when the holding device 340 is in the first orientation) from the edge 350 and has a dogleg shape.

[0142] Each second slot 349 can receive therethrough an elongate article 352 in the form of a fence wire when the holding device 340 is in the first orientation shown in FIGS. 28 to 30. Each second slot 349 is defined in the respective second portion 344 a predetermined distance from the first portion 342. Therefore, when the holding device 340 is clamped to the ground in the first orientation shown in FIGS. 28 to 30, the elongate article 352 is held a predetermined distance above the ground.

[0143] Each second portion 344 has a ground piercing formation in the form of an inwardly tapered free end 354. Each tapered free end provides a point to facilitate inserting the second portions 344 into the ground when the holding device is in the second orientation shown in FIGS. 31 to 33, as also explained below.

[0144] In FIGS. 28 to 30, the holding device 340 is shown in a first orientation. The securing device 10 is arranged to extend through the first portion 342 by passing the shaft portion 14 into the first slot 346 via the edge 348. The securing device 10 is then screwed into the ground 101 as described above.

[0145] When the holding device 340 is in the first orientation, the second portions 344 project upwardly from the ground 101, as shown in FIG. 28, and the engaging portion 22 of the securing device 10 is disposed between the second portions 344. The elongate article 352 can then be received in the second slots 349, thereby ensuring that the elongate article 352 is held the predetermined distance above the ground.

[0146] Referring to FIGS. 31 to 33, the holding device 340 is shown in the second orientation. The securing device 10 is arranged to extend through the first portion 342 by passing the shaft portion 14 into the first slot 346 via the edge 348, but the engaging portion 22 is disposed on the opposite side of the first portion 342 compared to the position of the engaging portion 22 when the holding device 340 is in the first orientation.

[0147] When the holding device 340 is in the second orientation, the second portions 344 are driven into the ground 101 when the securing device 10 is screwed into the ground 101. Thus, the holding device 340 can be arranged so that one of the wires 222 can be clamped between the first portion 342 and the ground 101 (see FIG. 31), thereby securing the wire 222 in place.

[0148] FIGS. 35 and 36 show another embodiment of the holding device, generally designated 360, which is formed of an elongate article, such as a wire. The holding device 360 can be used in first or second orientations, similar to the holding device 340 described above.

[0149] The holding device 360 shown in FIGS. 35 and 36 comprises a first portion 362. A pair of second portions 364 extend from the first portion 362. The second portions 364 extend from the first portion 362 in the same direction as each other, and are disposed at right angles to the first portion 362.

[0150] The first portion 362 includes a first formation in the form of a spiral region 366 through which the shaft portion 14 of the securing device 10 can be received. Each second portion 364 has a hook portion 368 at its free end for holding an elongate article, which may be a fence wire 352 (shown in broken lines in FIG. 38). The hook formations 368 extend from the second portions in opposite directions, as shown in FIG. 37, to help prevent the elongate article from being dislodged from the hook formations 368.

[0151] When the holding device 360 is in the first orientation, shown in FIG. 38, the securing device 10 is arranged so that the shaft 14 extends through the spiral region 366. When the securing portion 20 is screwed into the ground, the engaging portion 22 clamps the spiral region 366 to the ground, thereby clamping the holding device 260 to the ground. The second portions 364 extending upwardly from the engaging portion 22. The fence wire 352 can then be received in the hook formations 368. The fence wire 352 is thus held at a predetermined distance above the ground.

[0152] When the holding device 360 is in the second orientation, shown in FIG. 39, it can be used to clamp the lower region of a fence to the ground, such as a fence wire 222 of the lower region 226 of the fence 228 shown in FIG. 22. The fence wire 222 is shown schematically in FIG. 39 in broken lines. The second portions 364 are inserted into the ground in a position so that one of the wires 222 is received between the second portions 364.

[0153] The securing device 10 is arranged through the spiral region 366 and screwed into the ground as described above. The engaging portion 22 clamps the spiral region 366 to the ground with the second portions 364 driven into the ground by the securing device 10. The first portion 362 is clamped onto the wire 222 to secure the lower region 226 of the fence 228 to the ground.
