Figures 1 to 4 show a securing device 10 comprising a securing pin 11. In at least
one embodiment described herein, the ng device 10 comprises an erosion
control securing pin for securing an article in the form of geotextile matting 100 (see
Figures 3 and 4) to the ground 101 to reduce erosion of the ground 101. However,
it will be appreciated by the d 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
The ng 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.
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
Figure 7) around which the securing portion 20 s. The securing portion 20
extends radially dly from the main shaft portion 14. The securing portion 20
and the main shaft portion 14 are coaxial with each other.
The securing n 20 s 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
than prior art pins.
Referring to Figures 3 and 4, the ng device 10 is shown in use with a region
of the g 100. It will be appreciated by those skilled in the art that the region
of the matting 100 shown in Figures 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 Figure 4, so that the elongate member 12 can be
seen.
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.
As indicated above, the g 100 extends over a much larger area than shown
in Figures 3 and 4. In view of this, the use of a plurality of the ng pins 10 may
be required.
Referring again to Figure 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.
Referring to Figures 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.
The drive transmission device 102 comprises a receiving n 104 for receiving
the mounting member 24 of the ng device 10. The receiving n 104
defines a rectangular recess 106, in which the mounting member 24 can be
ed. When the mounting member 24 is received in the recess 106, the
receiving portion 104 is ed by the engaging portion 22, as shown in Figure 7
and 8. This has the advantage, in the embodiments bed herein, of stabilising
the securing device 10 on the drive transmission device 102.
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 rical and can be received by a standard chuck of
a hand operated drill.
A frustoconical portion 110 extends between the connecting member 108 and the
ing portion 104.
In use, the drive transmission device 102 is connected to the hand operated drill in
a manner that would be tood by those skilled in the art. The securing device
is mounted n 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.
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 g 100. The driving tool can then
further drive the securing device 10 to urge the g 100 into tighter engagement
with the ground 101, thereby securing the matting 100 to the ground 101.
Figures 9 to 20 show a further embodiment of a drive transmission device lly
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.
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 dly from a central region 214 of the receiving
portion 204. The main region 206A also has an axially extending side opening
211 B.
The recess 206 also has a support region 2068, which extends laterally from the
main region 206A in a side of the ing portion 204. The support region 2068
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
2063 of the recess 206 extends radially ly from a laterally extending side
opening 211C. The laterally extending side opening 211C extends laterally relative
to the y extending opening 21 1 B.
Figures 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 2063 of the recess 206. When so received, the mounting member 24
s 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 suppoted by the support surface 218.
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 Figures 14 and 15. this
provides the advantage, in the ments described herein, of stabilising the
ng device 10 on the drive transmission device 202.
Figures 16A to 168 show the arrangement of the securing device 10 on the drive
transmission device 202 and the driving of the ng device 10. In Figure 16A,
the drive transmission device 202 and the securing device 10 are shown separate
from each other. Figure 163 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. Figure 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.
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 te member which may be substantially
cylindrical or have a hexagonal profile. The connecting member can be ed
by a chuck of a standard hand operated drill.
Figures 17 and 18 show a sleeve 219 provided around the ing portion 204.
The sleeve 219 s an open end 221A through which the engaging portion 22
of the securing device 10 can be received. The sleeve has an opposite end 2218
having a cover 223 extending across the ing portion 204. The cover defines
an aperture 225 through which the connecting member 220 extends.
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.
Figures 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. Figure 19 shows the drive transmission device 202 without the
sleeve 219. Figure 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 n is ed by, and s through, the ng portion 22.
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.
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 es

transmission device 202 is in a driving position relative to the ng pin. In this
position, the force applying wall 208 is moved into engagement with the mounting
member 24.
Continued rotation of the force transmission device 202 rotates the ng device
about the main shaft n 14. By pressing down on the drill, the user moves
the drill towards the ground as the securing device 10 is d into the ground.
When the end face 212 of the drive transmission device 202 engages the matting,
the continued on 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.
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 Figures 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.
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 ments of the drive ission arrangements
described above provide the advantage that the ng device 10 is driven into
the ground until the engaging portion 22 is flush with the surface of the ground.
