Abstract:
A partition assembly comprising:a housing; and a partition cassette capable of being inserted into and removed from said housing, said partition cassette comprising: a pair of mounting plates; a partition support member rotatably mounted between said mounting plates; a partition member coupled to said partition support member, said partition member and partition support member adapted to roll said partition member from a rolled up position in which said partition member is rolled up on said partition support member to an unrolled position in which the partition member is no longer rolled up on said partition support member; a rod disposed within and coaxial with said partition support member; a torsion spring disposed between said rod and said partition support member, said torsion spring having a first end coupled to said rod and a second end coupled to said partition support member; a tension adjustment mechanism having a housing and an internal mechanism coupled to said rod, said tension adjustment mechanism being adapted to rotate said rod with respect to said partition support member; and a locking member demountably attached to the housing of said tension adjustment mechanism, said locking member adapted to engage said rod when said locking member is attached to said housing to prevent rotation of said rod and to disengage said rod when said locking member is detached from said housing, said locking member engaging said rod to transmit torque from said torsion spring to said housing and to prevent transmission of torque from said torsion spring to said internal mechanism.
