Abstract

The invention relates to a sliding or roller shutter or door which consists of a plurality of generally similar laths or planks hinged together by elastomeric members attached to adjacent edges of the laths or planks. Preferably, the edges of the laths or planks are formed with longitudinally extending keyhole shaped shots, and the elastomeric hinge members are formed with opposite enlarged portions received in the slots in the laths or planks.

Claims

1. A sliding shutter comprising:

a plurality of abutting laths having opposite substantially planar faces and abutting longitudinal edges, each said lath having a slot of generally keyhole shape cross-section extending along each said longitudinal edge, and each keyhole slot opening from the lath at a junction between the longitudinal edge and a face of the lath; and

an elongate flexible elastomeric hinge member of constant cross-section having an opposite pair of enlarged portions and a central flexible web portion connecting the opposite enlarged portions, one said enlarged portion being housed in the said keyhole slot in the edge of one said lath and the other said enlarged portion being housed in the said keyhole slot in the edge of an abutting lath for hingedly connecting the laths in an abutting relationship,

the elastomeric hinge members being tensioned when the faces of the laths are co-planar by folding of the central web portion about the respective edges of the laths to pull said abutting edges of the laths together.

2. A shutter according to claim 1 wherein the elastomeric members are of constant cross-section and the opposite enlarged portions are joined by a web.

3. A shutter according to claim 2 wherein the elastomeric members are dumb-bell shaped in cross-section.

4. A shutter according to claim 1 wherein the laths have a predetermined length along their longitudinal edges and the elastomeric members extend along the entire edge length of the laths.

5. A shutter according to claim 1 wherein the laths are formed from a high impact plastic.

6. A shutter according to claim 1 wherein the laths have hollow interiors.

7. A shutter according to claim 6 wherein the hollow interior of the laths is filled with a thermally insulating material.
