DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a barrier structure.
In accordance with the present invention there is provided a barrier structure comprising: engaging parts, respectively; and upper engaging parts to their respective engaging portions.
Preferably said support members are inserted into a base so as to secure said lower engaging pans to their respective engaging portions.
Preferably said engaging portions comprise slots.
Preferably said slots include upper slots adjacent a first end of said members to receive said upper engaging parts, and lower slots adjacent a second end of said members to receive said lower engaging parts.
Preferably said engaging pans are protrusions disposed on the sides of said barrier means.
Alternatively the engaging pans may comprise slots and the engaging portions may comprise protrusions.
The present invention also provides a method of erecting said structure, comprising: portions; portions; and
Preferably said upper parts are caused to engage their respective engaging portions by pivoting said barrier means after the lower parts have been caused to engage their respective engaging portions.
Preferably said method further comprises causing said support members to be received in said base before said barrier means is pivoted.
Preferred embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings wherein:
FIG. 1 is a front view of a first preferred embodiment of a barrier structure;
FIG. 2 is a perspective view of the barrier structure illustrating how it is erected;
FIG. 3 is a side view of a rail of the structure;
FIG. 4 is a side cross-sectional view of the base of a post of the structure with the rail attached thereto;
FIG. 5 is a side cross-sectional view of the top end of a post;
FIG. 6 is a side view of the top end of the post with a cap fitted thereto;
FIG. 7 is a front partial cross-sectional view of the top end of a post;
FIG. 8 is a perspective view of a nylon ferrule of the structure; and
FIG. 9 is a cross-sectional view of the ferrule attached to a bar of the structure;
FIG. 10 is a partial perspective view of a second preferred embodiment of a barrier structure;
FIG. 11 is a partial perspective view of a third preferred embodiment of a barrier structure; and
FIG. 12 is a partial perspective view of a fourth preferred embodiment of a barrier structure.
A barrier structure 2, as shown in FIG. 1, includes a number of rails 4 which are supported by a series of posts 6. The posts have caps 8 fitted over the top ends thereof and stand in respective bases 10. The bases 10 sit on a floor structure 12, which may comprise a verandah, balcony or merely the ground. The rails 4 include a plurality of vertical bars 14 and two upper horizontal bars 16 and 18 and two lower horizontal bars 20 and 22.
The second upper and lower bars 18 and 22 are slightly longer and protrude past the ends of the first upper and lower bars 16 and 20, as shown in FIG. 2, and include disc-shaped knobs, 24 and 26 respectively disposed on the ends thereof. The knobs 24 and 26 are adapted to be received by respective slots 30 and 32 disposed in the sides of the posts 6 at each end thereof.
The posts 6 are elongate hollow tubes having a rectangular cross-section. The slots 30 disposed at the upper end 34 of the posts 6, as best illustrated in FIGS. 2, 5 and 7, include a horizontal slot portion 36 which is provided in the respective side 38 of the post 6 and a vertical slot portion 40 which is provided in the front of the post 6. The vertical slot portion 40 is configured to enable a knob 24 of the upper bar 18 to be passed therethrough so that the knob 24 is then disposed in the post 6 and part of the upper bar 18 rests in the vertical slot portion 36 at the end thereof, as shown in FIG. 5. The knobs 24 prevent the upper bars 18 from being removed longitudinally from the post 6 in the direction of the axes of the bars 18.
To secure the ends of the bars 18 fully and prevent them being removed via the vertical slot portion 40 a cap 8, as shown
