PN2115 March 30, 1995 The following Statement is a full description of this invention including the best method of performing it known to me/us: II i~~uuu. 2 The present invention relates to a bollard. Bollards are used in towns and cities as a means of preventing access to areas by vehicles. Bollards are also increasingly being used as a security devise against vandalism and the like in front of fragile areas such as large glass windows or doors.

The placement of a bollard in front of a window prevents vehicles being driven into the window causing damage. It would also be beneficial if other areas such as roller doors could also be protected in this way. However, in the case of roller doors or other doonrways it is important that the full area in front of the doorway remains clear during the daytime, or as required, to allow delivery vehicle full access. Thus traditional bollards are not satisfactory as they restrict access to the doorway.

The present invention provides a bollard which may be securely placed in position to protect the structures, but also removable, thus allowing full access to an area during the day.

According to the present invention there is provided, a bollard including a body and base 00 section in which the body is arranged to be releasably engaged with the base section wherein 15 the base section has a transversely extending pin, the body has a latch means mounted therein, 0: the latch means being pivotable about a transverse axis and including an open ended slot, the 0*0o latch means being arranged to be pivotable between a first position in which the slot in the latch means is engaged with the pin and extends substantially horizontally with the open end **:thereof facing laterally such that the body cannot be removed from the base section and a S 20 second position at which the slot in the latch means is extended substantially vertically with the open end thereof facing downwardly such that the body can be removed from the base 040000 section.

The present invention will now be described, by way of example, with reference to the accompanying representations in which:- Figure 1 represents a side view of a bollard in accordance with the present invention; Figure 2 represents a perspective view of a lower section of the body of the bollard of Figure 1; Li Figure 3 represents a perspective view of bollard base and a base cap.

3 Referring to the drawings, there is shown a bollard 100 which includes a body 1, a base 2, a cap 4, and a latch means 3.

The body 1 of the bollard 100 is formed by a hollow tube which is open at the bottom end.

At the bottom of the body 1 there are two, vertical slots 7 extending upwardly into the body 1. The slots 7 are located in the tube wall on opposed sides of the body 1. Two pin guides 10 are welded within the bottom of the body 1. The pin guides 10 are in the form of a parallel flanges extending inwardly from an inside wall of the body 1.

Between the pin guides 10 is located the latch means 3. The latch means 3 pivots about a pivot pin 11. The pivot pin 11 extends horizontally between the two pin guides 10. At a lower end of the latch means 3 is a hole. A cam rod 6 is secured to the latch means 3 at the hole. Another end of the cam rod 6 is secured to a cam lock 5. The cam lock 5 may be key operated. At the top of the bollard is placed the cap 4.

The cap 4 has a threaded rod 14 which passes through a hole 13 in the top of the body 15 1 of the bollard 100. The threaded rod 14 is secured by a nylox nut 9.

The base 2 is formed of a hollow tube which is open at both ends. The interior of the base 2 is slightly larger than the exterior of the body 1. The body 1 is able to longitudinally slide within the base 2.

At the bottom of the base 2, two flat bars 12 are welded in a horizontal position.

At the upper end of the bollard base 2 is welded a pin 8. The pin 8 is positioned to extend horizontally from one side of tbe interior of the base 2 to an opposite interior side.

The method of operation and use of the bollard will now be described tt :0..etn oiotlyfo n ieo h itro ftebs oa poieitro sie ii 4 The bollard 100 is installed at a desired location as follows. The base 2 is concreted into the ground such that the upper end of the base 2 finishes level with the ground.

The bollard 100 is used as follows. The.lower end of the body 1 slides down into the base 2. When the body 1 is in position the pin 8 is located within the slots 7. The slots 7 assist the body 1 in being correctly located within the base 5. The body 1 now rests on the base pin 8. A key is rotated in the cam lock 5 which pushes down the cam rod 6, thereby pivoting the latch means 3 to latch on to the pin 8. In this position the body 1 cannot be removed as it is secured to the pin 8 (and thus also to the concreted base 2) by the latch means 3.

To remove the body 1, the cam lock 5 is rotated by the key, in the opposite direction, thereby causing the cam rod 6 lift up and thereby pivoting the latch means 3 to unlatch the pin 6, thus allowing the body 1 to move upwards free from the pin 8. A base cap 15 may then be positioned in the upper opening of the base 2 to prevent any •debris from entering the upper opening.
