Abstract:
A casing for a projection screen system comprising:a spine including a top wall comprising a first attachment module;a removable fascia for covering a projection screen mounting roller, said fascia comprising a second attachment module;wherein one of said first and second attachment modules comprises a locking lip;wherein the other of said first and second attachment modules comprises a surface defining a socket adapted to receive said locking lip;wherein said locking lip and said socket are structured and arranged such that said locking lip is insertable a first distance into said socket when said fascia is arranged in a first position relative to said spine, and such that said locking lip is insertable a second distance greater than said first distance into said socket when said fascia is moved relative to said spine from said first position to a second position, whereby said first and second attachment modules are locked together when said locking lip is inserted in said socket and said fascia is disposed in said second position to prevent inadvertent removal of said fascia from said spine; andat least one end cap attached to said spine at a longitudinal end of said top wall, said at least one end cap when attached to said spine being longitudinally spaced from said fascia to avoid interfering with the moving of said fascia between said first and second positions, wherein said at least one end cap includes a resilient clip adapted to engage said fascia when said fascia is disposed in said second position to prevent moving of said fascia toward said first position.
