4. The hinge according to claim 3 , wherein the dampener has a substantially cylindrical body having a protrusion extending orthogonally therefrom relative to the longitudinal axis of the dampener, wherein at least a portion of the cavity resiliently deforms to receive the protrusion of the dampener within the cavity to at least partially house the dampener.
5. The hinge according to claim 4 , wherein the cavity comprises one or more cavity walls including a pair of curved walls, wherein edges of the walls are define a gap varying in width along a longitudinal axis of the cavity, wherein the protrusion has a width that is greater that a narrowed section of the gap, wherein a sufficient force applied to the dampener causes the walls to deform in order for at least a portion of the dampener to be housed and retained within the cavity.
6. The hinge according to claim 5 , wherein the gap includes a first section adjacent to the narrowed section which the protrusion is able to be received therein when progressively being inserted into the cavity, and a second section opposingly adjacent to the narrowed section which the protrusion is able to be received therein after the sufficient force is applied to the dampener to cause the resilient deformation of the walls.
7. The hinge according to claim 5 , wherein the protrusion is tapered and elongated along a longitudinal axis of the dampener.
8. The hinge according to claim 3 , wherein the dampener housing has an upper and lower support surface which are receivable between upper and lower ribs extending from an inner surface of the first front leaf component.
9. The hinge according to claim 8 , wherein the upper and lower ribs have a threaded stem which threadably engage the first set of fasteners, wherein the upper and lower support surfaces of the dampener housing include a recess to tight fittingly accommodate a portion of the respective threaded stems.
10. The hinge according to claim 3 , wherein the dampener housing has a pair of arms extending from a housing body, the pair of arms including a pair of holes for receiving therethrough the first set of fasteners.
11. The hinge according to claim 10 , wherein the dampener housing includes a plurality of pairs of holes, wherein during installation of the hinge the first set of fasteners are selectively threaded through one of the pairs of holes which align with the pair of holes in the portion of the first panel.
12. The hinge according to claim 1 , wherein the first and second leaf assemblies include a plurality of knuckles defining a barrel housing the spring, wherein a longitudinal axis of the spring being coaxial with the hinge axis, wherein the hinge further includes:
a barrel cap having an inner and outer neck, wherein the outer neck has a first engaging surface, the barrel cap being received within one end of the barrel; and
a spring tensioning component located within a void defined by the inner neck, the spring tensioning component being coupled to a first end of the spring, the spring tensioning component having a second engaging surface which engages with the first engaging surface to restrict rotational movement of the spring tensioning component relative to the barrel cap whilst under bias of the spring;
wherein a sufficient rotational force applied to the spring tensioning component causes the rotational movement of the spring tensioning component relative to the barrel cap to increase the tension of the spring.
13. The hinge according to claim 12 , wherein the first and second engaging surfaces have corresponding sawtooth profiles.
14. The hinge according to claim 12 , wherein the spring includes a diametrically extending tail defining a first and second cavity with at least some of the coils of the spring, wherein the spring tensioning component includes a pair of protrusions which are received within the respective first and second cavities to enable rotational force applied to the spring tensioning component to be transferred to the spring to adjust the tension of the spring.
15. The hinge according to claim 14 , wherein the spring includes a further diametrically extending tail receivable within an aperture located in a wall of the first front leaf component, the wall having protrusions extending therefrom which are receivable within cavities defined by at least some of the coils of the spring and the further diametrically extending tail to couple the spring to the first front leaf component.
