Abstract
Abstract A unit for inclusion in a balustrade comprising a pair of rails each having a pair of opposed flanges, and a plurality of balusters each having adjacent each end a pair of transverse shoulders which are engaged behind the flanges of one or other of rails by inserting the end of the baluster between the flanges and rotating the baluster through a predetermined angle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
194 words
A balustrade unit comprising a pair of spaced apart channel section members, the open faces of the members being directed towards one another, the free edges of each of the members being turned inwardly to form a pair of opposed longitudinally extending flanges and a pair of longitudinally extending divergent resilient wings provided in the base of the channel section members and formed integrally therewith; a plurality of balusters extending between the channel section members, each baluster being provided adjacent each end with a pair of transverse shoulder, the balusters each having one crosssectional dimension adjacent each end smaller than the distance between the opposed longitudinally extending flanges such that the end can be inserted into the space between the flanges of one of the said channel section members and can then be rotated through a predetermined angle to engage the shoulders of the baluster adjacent the said end with the inner surfaces of said flanges and bring the end face into resilient engagement with said engagement means of the associated channel section member; and a spacing member extending between adjacent balusters, in juxtaposition with at least one of the said channel section members.
Claim 2
Dependent Claim
194 words
A balustrade unit comprising a pair of spaced apart channel section members, the open faces of the members being directed towards one another, the free edges of each of the members being turned inwardly to form a pair of opposed longitudinally extending flanges and a pair of longitudinally extending divergent resilient wings provided in the base of the channel section members and formed integrally therewith; a plurality of balusters extending between the channel section members, each baluster being provided adjacent each end with a pair of transverse shoulder, the balusters each having one crosssectional dimension adjacent each end smaller than the distance between the opposed longitudinally extending flanges such that the end can be inserted into the space between the flanges of one of the said channel section members and can then be rotated through a predetermined angle to engage the shoulders of the baluster adjacent the said end with the inner surfaces of said flanges and bring the end face into resilient engagement with said engagement means of the associated channel section member; and a spacing member extending between adjacent balusters, in juxtaposition with at least one of the said channel section members.
Claim 3
Dependent Claim
26 words
A balustrade unit as claimed in claim 1 including at least a pair of newel posts connected to the ends and/or sides of the balustrade unit.
Claim 4
Dependent Claim
17 words
A balustrade unit as claimed in claim 1 in which the balusters are of H-shaped cross section.
Claim 5
Dependent Claim
40 words
A balustrade unit as claimed in claim 1 in which each spacing member is of channel shape and fits resiliently between the flanges of one of the channel section members to cover the open face thereof between two adjacent balusters.
Claim 6
Dependent Claim
34 words
A balustrade unit as claimed in claim 1 in which the spacing member comprises a panel of a sheet material extending between adjacent balusters and being in juxtaposition with both of the channel members.
Claim 7
Dependent Claim
49 words
A balustrade unit as claimed in claim 1 in which the balusters are each provided adjacent each end with a pair of transverse slots defining the said shoulders and a further pair of shoulders opposed thereto, the further pair of shoulders engaging the outer surfaces of the said flanges.
Claim 8
Dependent Claim
37 words
A balustrade unit as claimed in claim 2 in which the channel members are provided adjacent each end with a pair of transverse slots which engage with a pair of opposed flanges formed on the newel post.
