The devices may also resist the unauthorised removal of items of commercial, retail or industrial equipment.

BACKGROUND TO THE INVENTION There is a need to provide security barriers intended to prevent or restrict unauthorised entry, passage, movement or use of an area enclosed by the barriers by light vehicle traffic. traffic.

971001,cmsdat.111stewartap,1 2- In some cases there is also a need to provide anti-ramming protection to showroom windows or factory roller doors.

It would be advantageous if the barriers could be securely locked in place to serve their intended function but could also be removed when required to allow authorised access to protected areas.

It would be an additional advantage if the locking function of the barriers could also serve the purpose of locking in place doors, gates or items of equipment.

The present invention seeks to provide a removable security bollard which is able to meet these needs.

SUMMARY OF THE INVENTION The present invention provides:a removable security bollard comprising an above-ground post member; and an in-ground mounted or on-ground mounted mating fundament; in which the mating fundament has a transversely mounted solid rod and the post member has two opposed inverted Lshaped slots each having a vertical arm and a horizontal arm, said slots located one on either side of a bottom edge of the post member; wherein, in use, when the post member is inserted into the mating fundament the slots slide over the rod and when the post member is then rotated about its vertical axis, the rod engages the horizontal arms of the slots thus locking the post member into the mating fundament.

971001pnsdat111stwartnap,2 -3 In another aspect the invention provides:- A method for locking an item to the ground or for preventing the removal of a piece of equipment from its desired location comprising the use of a removable security bollard according to the invention.

PREFERRED ASPECTS OF THE INVENTION It is preferred that the above ground post member is provided with at least one locking rod which is adapted to move longitudinally along the vertical axis of the post member from a first, retracted, position to a second, extended, position wherein, in use, when the locking rod is in its extended position, the locking rod engages the rod 15 in the mating fundament such that the post member is o prevented from rotating.

Any locking mechanism as is known in the art may be provided to lock the locking rod in its first and/or second position. Suitable locks include camlocks, padlocks or restricted or security locks.

It is preferred that the locking rod is located within an interior portion of the post member.

It is most preferred that the post member is adapted with at least one guiding eye located above and/or below the horizontal arms of the slots through which eye the locking rod may pass to provide strength and rigidity to the locking rod.

The L-shaped slots may be oriented so that the post member can rotate in either a clockwise or anti-clockwise direction.

A circumferential collar may be provided around the post member and located at a point where it bears against the 971001 nsdt.11 1,steartcap,3 4 upper edge of the mating fundament to evenly distribute the weight of the post member and provide additional strength to the bollard because of its load spreading effect.

The collar may be further adapted to form a flange in which case it is able to deflect rain water from running into the mating fundament.

The circumferential collar may also serve the purpose of a locking or retaining collar to lock an item such as a plate between the collar and the mating fundament. In this case the collar is located at a selected distance above the upper edge of the mating fundament to allow for the thickness of the item to be locked into place.

e It is preferred that the locking collar is located about above the upper edge of the mating fundament.

It is preferred that the mating fundament is mounted inground.

i: If a mating fundament is to be inserted in an existing ground surface, the outer surface of the mating fundament may be provided with one or more triangular wing members protruding radially and mounted at or near the upper edge of the mating fundament. This type of in-ground mating fundament is known as a "winged in-ground unit". The wing members are of suitable size and rigidity to resist the rotation of the mating fundament within the ground.

Generally, the ground surface will be core drilled and the mating fundament will be fixed into the resulting hole by means of an adhesive such as epoxy glue.

If a mating fundament is to be inserted in a newly formed ground surface such as newly poured concrete, it is preferred that the outer surface of the mating fundament is provided with one or more radially projecting fins and/or 97 1001,cmsdat.1 1.stewrtxcap,4 5 rods which are oriented along the longitudinal axis of the mating fundament. This type of in-ground mating fundament is known as a "star in-ground unit". The fins and rods are of suitable size and rigidity to bed into the newly formed surface and to resist the rotation of the mating fundament within the ground.

It may be advantageous to provide a series of blisters on the surface of the post member which is inserted into the mating fundament. The blisters serve the purpose of taking up any slackness of fit of the post member into the mating fundament. It is preferred that the blisters are circumferentially arranged at four equidistant points at or near the base of the post member and/or at four equidistant points at or near a region of the post member which corresponds to the upper edge of the mating fundament.

The top of the post member may be provided with a handle as is known in the art so that the post member can be more readily manipulated.

Moisture may seep out of the ground, evaporate and rise to the top of the post member at which point it may condense and induce rust in the post member and/or the mating fundament. To reduce this likelihood, it is preferred to provide a breather vent in the form of an open nipple at the top of the post member.

The bollard may be constructed of any material and to any design and length which is able to achieve the promise of the invention. It is preferred that the post member and mating fundament are tubular in form. In particular circumstances the tube may be square or oblong in cross section but it is preferred that the bollard is substantially in the form of a cylindrical tube. It is preferred that the bollard is constructed in steel and more preferred that it is constructed from high tensile steam 971001 xmsdat.11 stzcwaiap.S -6 pipe. The steam pipe may be of 3.5-7.0mm wall thickness but is preferred to be of 5.6mm wall thickness.

Removable security bollard Post member Mating fundament Slot Rod Locking rod Eye Collar Wing Blister Handle Breather vent Cam lock Tamper shield Anti-rotation rod Roller door locking plate Braced support Automatic teller machine restrainer Trailer locking bracket Perforation C-cut out Impact load spreader base Brace 971001xmsdat.111,sewartap,7 8 DETAILED DESCRIPTION WITH RESPECT TO THE DRAWINGS In Figures 1, 2 and 3 is shown a removable security bollard 1 according to the invention.

The removable security bollard 1 comprises a post member 2 and a mating fundament 3. The mating fundament 3 comprises a solid transversely mounted rod 5 and the post member 2 is provided with two inverted L-shaped slots 4 at either side of the bottom edge.

When the post member 2 is inserted into the mating fundament 3, the vertical arms of the slots 4 pass over the rod 5 and the collar 8 rests against the upper edge of the mating fundament 3. By rotating the post member, the rod 5 engages the horizontal arms of the slots 4 and the post member 2 is thus locked into the mating fundament 3 in such e a manner that the post member 2 cannot be lifted directly out of the mating fundament 3.

To prevent the post member 2 from being rotated and then lifted out of the mating fundament 3, a locking rod 6 is employed. The locking rod 5 is passed through two eyes 7, one on either side of the horizontal arms of the slot 4.

i When the locking rod 6 is extended beyond the line of the slot 4, it prevents the rotation of the post member 2 by bearing against the rod The arrangement of the locking rod 6 and cam lock 13 within the post member 2 is illustrated in Figure 6.

Illustrated in Figure 12 is the use of a removable security bollard according to the invention for the purpose of locking various devices to the ground.

For this use the collar 8 is located about 5mm above the 9710o 1.nsdaL111,xtewArtap,8 9 upper edge of the mating fundament 3. When the post member 2 is passed through a perforation 20 in a device (16, 17, 18 or 19) and engaged in the mating fundament 3 the collar 8 resists the upwards movement of the device (16, 17, 18 or 19).

A roller door locking plate 16 is an approximately 150mm wide zinc coated steel right-angled plate of 4mm thickness and is blind bolted to the lower edge of a roller door.

When the door is lowered to the ground a post member 2 is passed through the perforation 20 in the roller door locking plate 16 and locked into a mating fundament 3.

A similar principle is applied to an automatic teller 15 machine restrainer 18. One or more restrainers 18 are located around an automatic teller machine and locked into the ground as described above.

To secure a trailer to a removable security bollard 1 a Ushaped trailer locking bracket 19 is employed. The bracket 19 is passed around a suitable part of the trailer chassis and then, in turn, a post member 2 is passed through the two perforations 20 and locked as described above.

When additional ramming or impact resistance is required a braced support 17 is employed. The braced support 17 comprises a tubular steel brace 23 mounted on an impact load spreader base 22. A C-cut out 21 at the upper end of the brace 23 is adapted to engage a post member 2. The post member 2 is passed through a perforation 20 in the braced support 17 and locked as previously described. Not shown in Figure 12 is a half round support collar mounted on the post member 2 at a point where it engages the Ccutout 21 which thus forms the remaining half of the collar. This arrangement prevents rotation of the braced support around the post member 2.
