Claim 13

The combination as claimed in claim 10 wherein said connector piece includes a portion extending through at least one of said slots of said rails.

Claim 14

The combination as claimed in claim 9 wherein adjacent ends of said rails are mitred and said sections of said connector piece are angled to fit within said channels.

Claim 15

The combination as claimed in claim 9 wherein said connector element includes a portion extending through said slot.

Claim 16

An extruded rail comprising a body having a longitudinally extending flat side surface, an L-sectioned channel extending longitudinally through the rail and having one limb parallel to said side surface and another limb extending from a junction with an end region of said one limb, at an angle to said side surface and to that side of said one limb remote from said side surface, an end region of said one limb remote from said junction being closed and a longitudinal slot opening from said side surface to said one limb at a region intermediate said closed end region and said junction.

Claim 17

An extruded rail comprising a body having a longitudinally extending flat side surface, an L-sectioned channel extending longitudinally through the rail and having one limb parallel to said side surface and another limb extending from a junction with an end region of said one limb, at an angle to said side surface and to that side of said one limb remote from said side surface, an end region of said one limb remote from said junction being closed and a longitudinal slot opening from said side surface to said one limb at a region intermediate said closed end region and said junction.

Claim 18

An extruded rail comprising a body having a longitudinally extending flat side surface, an L-sectioned channel extending longitudinally through the rail and having one limb parallel to said side surface and another limb extending from a junction with an end region of said one limb, at an angle to said side surface and to that side of said one limb remote from said side surface and a longitudinal slot opening from said side surface to said one limb at a region spaced from said junction of said limbs, said slot and said one limb defining a generally T-shaped channel.

Claim 19

An extruded rail comprising a body having a longitudinally extending flat side surface, an L-sectioned channel extending longitudinally through the rail and having one limb parallel to said side surface and another limb extending from a junction with an end region of said one limb, at an angle to said side surface and to that side of said one limb remote from said side surface and a longitudinal slot opening from said side surface to said one limb at a region spaced from said junction of said limbs, said slot and said one limb defining a generally T-shaped channel.

Claim 20

In combination, an extruded rail comprising a body having a longitudinally extending flat side surface, an L-sectioned channel extending longitudinally through said rail and having one limb parallel to said side surface and another limb extending from a junction with an end region of said one limb at an angle to said surface and to that side of said one limb remote from said side surface and a longitudinal slot opening from said side surface to said one limb at a region spaced from said junction of said limbs, said side surface extending to both sides of said slot and said one limb and said slot defining a generally T-shaped channel, and a connector piece comprising a longitudinally extending portion of similar cross section to said channel said longitudinally extending portion being received within said channel.
