"A BOLLARD" INVENTION TITLE: DETAILS OF ASSOCIATED PROVISIONAL APPLICATION NO'S: APPLICATION NO:

LODGED:

PP0351 November 13th, 1997 The following Statement is a full description of this invention including the best method of performing it known to me/us: 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 security devices 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 doorways 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 is also submersible, thus allowing full access to an area during the day.

3. According to one aspect of the present invention there is provided a bollard comprising; a base section; a body including a pivotable latch means adjacent a lower end thereof, the body being slidable between a lowered position in which it is substantially fully contained within the base section and the latch means is retracted into the body, and a raised position in 20 which the body extends substantially above the base section and a portion of the latch means extends through an opening in the body into a recess in the base section, to prevent movement of the body relative to the base section; a locking means adjacent an upper end of the body, the locking means being moveable between a first position and a second, locked position; and 3 an elongate member interconnecting the locking means with the latch means, whereby moving the locking means to the second position causes longitudinal movement of the elongate member, the longitudinal movement of the elongate member causing the latch member to pivot between the position in which the latch means is retracted within the body and the position in which a portion of the latch means extends through the opening in the body.

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

I Referring to the drawings, there is shown a bollard 10 which includes a body 12, a 15 base section 14, a cap 16, and a latch means 18.

The body 12 of the bollard 10 is a hollow tube which is open at both ends. The body 12 includes a first securing plate 22 fixed between opposing interior walls of the body 12 at an upper end thereof The first securing plate 22 is provided with an aperture which is arranged to be aligned with an aperture in a wall of the body 12. A rotatable cam lock 20 is arranged to be received through the apertures in the body 12 and the first securing plate 22. The rotatable cam 20 lock may be key operated.

Also provided are two parallel flanges 24, mounted at a lower end of an interior wall of the body 12. Between the parallel flanges 24 is mounted a pivot pin 26. The latch means 18 is arranged to pivot about the pivot pin 26. Further, an opening 40 is provided in the body 12 between the flanges 24.

4 The latch means 18 is provided with a first arm 28 and a second arm 30 disposed at an angle between 450 or 900 to one another. The first arm 28 is provided with a first aperture 32 and a second aperture 34 at an end remote from the pivot pin 26. An elongate member 37 is secured at a lower end to the first aperture 32 and is secured at an upper end to the rotatable cam lock 20. A tension spring 36 is connected between the second aperture 34 and an interior wall of the body 12 at a point adjacent the lower end of the body 12.

The second arm 30 of the latch means 18 is provided with an outwardly extending lug member 38. Further the lug member 38 includes an upwardly extending portion 39 at an end remote from the second arm 30. The latch means 18 is arranged to be pivoted by the raising of the elongate member 37 from a first position in which the lug member 38 on the second arm 30 extends through the opening 40 in the body 12 as :'lshown in Figure 3 to a second position in which the lug member 38 on the second arm 30 is retracted inside the body 12 as shown in Figure 2. In the second position, a the tension spring 36 is expanded as shown in Figure 2 such that on release of the :C elongate member 37, the tension spring 36 causes the latch means 18 to pivot back to S-the first position.

The cap 16 is provided with a handle 44. Further, a second securing plate 50 is provided between interior walls of the body 12 at an upper end thereof The cap 16 is 20 arranged to be placed over the open upper end of the body 12 and secured by security bolts 48 fixed through corresponding apertures in the cap 16 and the second securing plate 50. Also provided is a first sealing means 46. The first sealing means 46 is a flexible flap arranged to extend outwardly from around the cap 16.

A plurality of spacers 42 are welded to external walls of the body 12 at a lower end thereof Further, a second sealing means 43 is provided adjacent the spacers 43 between the body 12 and the base section 14. The first and second sealing means 46 and 43 are arranged to prevent the ingress of water or debris to the base section 14.

The base section 14 is formed of a hollow tube which is open at both ends. The body 12 is able to longitudinally slide within the base section 14. At a lower end of the base section 14, two lugs 52 are welded to opposing interior walls. Further, the base section 14 is provided with a recess 54 at an upper end thereof The recess 54 includes a downwardly protruding portion 55 on an upper surface. The base section 14 is provided with a flange 56 at an upper end and securing means 58 attached at a lower end.

A security plate 60 is provided to be fastened to the flange 56 at the upper end of the base section 14 by security bolts 62. The security plate 60 has an opening arranged to align with the opening in the upper end of the base section 14.

In use, the base section 14 is concreted into the ground such that the upper end.of the base section 14 is level with the ground. The rotatable cam lock 20 is rotated so that 15 the elongate member 37 is raised. The latch means 18 is thereby pivoted from the first o• position in which the lug member 38 is extended through the opening 40 to the second position in which the lug member 38 is retracted inside the body 12. The body 12 is then lowered into the base section 14 until it rests on the lugs 52. The upper end of the i body 12 will now be level with the ground.

20 The security plate 60 is secured to the flange 56 of the base section 14 by security •bolts 62. The aperture in the security plate 60 is arranged so that the body 12 can be raised through the aperture in the security plate 60 until the spacers 42 come up against the security plate 60. This prevents the body 12 being removed from the base section 14 after the security plate 60 is installed.

6 The bollard 10 is used as follows. The body 12 is raised by pulling on the handle 11 until the opening 40 in the body 12 is in alignment with the recess 54 in the base section 14. The force of the tension spring 36 will then rotate the latch means 18 to the first position in which the lug member 38 is extended through the opening 40 in the body 12 and into the recess 54 of the base section 14. The extension of the lug member 38 into recess 54 prevents the body 12 from sliding back down into the base 12. If the security plate 60 were to be removed, the upwardly extending portion 39 of the lug member 38 would come up against the downwardly protruding portion 55 of the recess 54 and still prevent removal of the body 12 from the base section 14.

To lower the body 12 into the base section 14, the cam lock 20 is rotated causing elongate member 37 to be raised. The latch means 18 will then pivot back to the second position in which the lug member 38 is retracted into the body 12, through opening 40. The body 12 is then free to slide under its own weight down into the base section 14 until it comes to rest on the lugs 52.

Modifications and variation such as would be apparent to a skilled addressee are considered within the scope of the present invention.
