Barrier connection system and method thereof

1. A barrier assembled from parts, the parts comprising:

first and second spaced posts; and

a rail interconnecting said first and second posts, wherein the rail is not inserted within the posts;

wherein

the first post, the second post, and the rail are hollow in at least a hollow region of the intended interconnection and each post includes an aperture and is connected to the rail by a coupling, wherein the coupling includes a connector;

the connector is arranged to extend through the aperture so that a first portion of the connector is arranged inside the hollow region of the post and a second portion of the connector is arranged inside the hollow region of the rail, the first portion and the second portion being a single piece;

a width of the first portion is smaller than a width of the second portion such that the second portion is configured to abut the post and cannot extend through the aperture into the hollow region of the post; and

the connector includes an abutment that is able to be arranged to prevent movement of the connector through the aperture in use while the second portion abuts the post and includes a second abutment arranged to act through an aperture within the rail;

wherein the connector comprises a main body and a moveable first fixing,

the first fixing is removable from the main body; and

the first fixing is arranged from an abutment position to a free position, and in the abutment position, the moveable first fixing forms the abutment; and

the connector is moveable relative to the rail so that, when the abutment is removed from the main body of the connector, the connector is able to move through the aperture in a direction to withdraw the first portion into only the hollow region of the rail while being fixed by the hollow region of the rail in all directions perpendicular to the direction so that the rail can subsequently be disassembled from the posts without increasing the distance between the two spaced posts, and when the abutment is in the abutment position and the second abutment is fixed to the rail, the connector is moveable relative to the hollow region of the rail to extend from the rail.

2. The barrier as claimed in claim 1 , wherein the abutment of the connector is arranged within the post.

3. The barrier as claimed in claim 2 , wherein the abutment is arranged to contact the inside of the post.

4. The barrier as claimed in claim 2 , wherein the abutment is in removable contact with the inside of the post.

5. The barrier as claimed in claim 4 , wherein the abutment is arranged to restrict in size in order to pass through the aperture.

6. The barrier as claimed in claim 1 , wherein the first fixing is an elongate pin.

7. The barrier as claimed in claim 1 , wherein the second portion of the coupling has a length great enough that the second portion of the coupling is configured to remain retained within the rail upon impact of an object with the barrier.

8. The barrier as claimed in claim 1 , wherein the aperture through the post is smaller than an inner dimension in the rail, the inner dimension being arranged to enclose the second portion of the coupling.

9. The barrier as claimed in claim 1 , wherein the second abutment is removable.

10. The barrier as claimed in claim 1 , further comprising a collar arranged to fit against the rail to one side and the post to the other.

11. The barrier as claimed in claim 1 , the first fixing is within the hollow region of the post when the first fixing is in the abutment position.

12. The barrier as claimed in claim 1 , the connector comprises a slot through which the second abutment extends when fixed to the rail, the slot allowing the connector to move relative to the second abutment and the hollow region of the rail.

13. A method of assembling and disassembling a barrier from parts, the method of assembly comprising:

providing a connector having a first portion and a second portion, the first portion and the second portion being a single piece, and a width of the first portion being smaller than a width of the second portion;

interconnecting a rail to a first post and a second post, wherein the rail is not inserted within the posts, wherein the first post, the second post, and the rail are hollow in at least a hollow region of the intended interconnection and each post includes an aperture;

the method of interconnection comprising:

coupling each post to the rail by the connector;

arranging the connector through the aperture so that the first portion of the connector is arranged inside the hollow region of the post and the second portion of the connector is arranged inside the hollow region of the rail, such that the second portion is configured to abut the post and cannot extend through the aperture into the hollow region of the post;

preventing movement of the connector through the aperture by an abutment arranged on the connector while the second portion abuts the post and simultaneously allowing the connector to move relative to the hollow region of the rail to extend from the rail; and

wherein the connector comprises a main body and a moveable first fixing,

the first fixing is removable from the main body;

the first fixing is arranged from an abutment position to a free position, and in the abutment position, the moveable first fixing forms the abutment; and

a second fixing extends through the connector and the rail and is fixed to the rail to form a second abutment for the connector;

the method of disassembly comprising:

disassembling the rail from each post by removing the abutment from the main body of the connector and allowing movement of the connector through the aperture in a direction to withdraw the first portion into only the hollow region of the rail while being fixed by the hollow region of the rail in all directions perpendicular to the direction such that the rail can be disassembled from the posts without increasing a distance between the two posts.

14. The method as claimed in claim 13 , the first fixing is within the hollow region of the post when the first fixing is in the abutment position.

15. The method as claimed in claim 13 , the connector comprises a slot through which the second fixing extends, wherein the slot allows the connector to move relative to the second fixing and the hollow region of the rail.
