A threshold strip for a transition between a pair of adjacent floor surfaces comprises a base <B>9</B> having a floor plate and a projection, a hinge shaft <B>30</B> having an opening which adjustably engages the projection and a cap <B>20</B> having a socket which pivotally receives the hinge shaft. The hinge joint between the hinge shaft and the socket may have teeth and recesses which engage with each other to provide a series of indexed positions. The base projection and the hinge shaft may have teeth and recesses which engage with each other to provide an expansion joint having a series of indexed positions. The floor plate may extend on both of two opposing sides of the projection and may comprise a pair of flanges. The opening in the hinge shaft may extend into the interior of the hinge shaft and may extend through the centre of the hinge shaft. The hinge shaft may comprise a body and a pair of supports <B>31, 32</B> which extend from the body and have a gap between them to define the opening. The hinge shaft supports may be formed with weakening notches to allow the ends of the supports to be broken off. A hinge shaft for such a threshold trim strip and a kit for assembling such a trim strip are also claimed. |
