Frame assembly for sheet material

A frame assembly according to any preceding claim, wherein there are a plurality of recesses in each inner frame section, in particular two or three recesses.

A frame assembly according to any preceding claim, wherein corner pieces are provided between the inner frame sections, the cross-sectional shape of the corner pieces corresponding to that of the inner frame sections.

A frame assembly according to any preceding claim, wherein a mounting insert is arranged within each recess of the inner frame sections, for assisting the correct location of the sheet material in the recess, said mounting insert optionally including internal ribs.

A frame assembly according to any preceding claim, further comprising a spacer element to increase the space between the first and second outer frame or to increase the length of the outer frames, whereby different sizes of inner frame sections can be fitted subsequently.

A frame assembly according to any preceding claim, wherein the first and second outer frames are provided with at least one respective projection and groove, so that their distance apart can be adjusted.

A frame assembly according to any preceding claim, comprising tightening means such as bolts for tightening and fitting the second outer frame to the first outer frame.

A frame assembly according to any preceding claim, comprising bolts for bolting the first outer frame to a surround which is part of the structure in which the frame assembly is to be mounted, the bolts being fitted transversely of the sheet material, preferably substantially parallel to the plane of the sheet material.

A frame assembly according to any preceding claim, wherein the cross-sectional shape of the space between the inner and outer frames corresponds to that of the inner frame sections.

A frame assembly according to any preceding claim, wherein a sealing and/or bonding material is provided in the recesses of the inner frame sections, for example a silicone bonding material.

A frame assembly according to any preceding claim, wherein the frame assembly is a window or door frame assembly and the sheet material is glass, clear, opaque, translucent or otherwise.

A frame assembly according to any preceding claim, wherein the inner frame sections and the outer frames are made of aluminium, steel, UPVC or other plastics or polymer material.

A frame assembly according to any preceding claim, wherein the first and/or second outer frames include a lip which in use engages over the inner frame section.

A frame assembly according to any preceding claim, wherein the sides of the inner frame sections are flexible, so that on holding of the inner frame sections between the outer frames, the sides of the inner frame sections can be compressed towards the sheet material.
