Abstract
Abstract A demountable partition for dividing a large room into smaller units and including a ceiling channel and a floor channel arranged in parallel and in vertical alignment. Wall panels are adapted to engage in the channels and spring means in the ceiling channel applies a downward force on the panels and floor channel. A trim strip is housed in the ceiling channel to distribute the spring load more evenly on the panel and improve the appearance of the ceiling channel when the panels are removed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
252 words
A demountable partition comprising: an upwardly-opening floor channel on a floor; a downwardly-opening ceiling channel affixed to the ceiling parallel to and above said floor channel, the depth of the ceiling channel being substantially greater than the depth of the floor channel and the ceiling channel having a pair of inwardly extending lips defining a slot; a trim strip engaged in the ceiling channel and having a width greater than the width of the slot; and spring means housed in the ceiling channel above the trim strip for biasing the trim stip into engagement with upper surfaces of the lips; and panels having a thickness slightly less than the width of the slot for sliding engagement in the ceiling channel between the lips, each of the panels having respective upper and lower ends engaged in the ceiling and floor channels, the upper ends of the panels being engaged against the underside of the trim strip whereby the trim strip is displaced upwardly of the lips and the spring means is compressed to provide a downward force on the floor channel, each of the panels being removable by displacing the panel upwardly to further compress the spring means and thereby release the lower end of the panel from the floor channel whereupon the panel is removed from the ceiling channel by first moving the lower end of the panel away from the floor channel and then lowering the panels so that the upper end of the panel is removed from the ceiling channel.

A demountable partition comprising: an upwardly-opening floor channel on a floor; a downwardly-opening ceiling channel affixed to the ceiling parallel to and above said floor channel, the depth of the ceiling channel being substantially greater than the depth of the floor channel and the ceiling channel having a pair of inwardly extending lips defining a slot; a trim strip engaged in the ceiling channel and having a width greater than the width of the slot; and spring means housed in the ceiling channel above the trim strip for biasing the trim stip into engagement with upper surfaces of the lips; and panels having a thickness slightly less than the width of the slot for sliding engagement in the ceiling channel between the lips, each of the panels having respective upper and lower ends engaged in the ceiling and floor channels, the upper ends of the panels being engaged against the underside of the trim strip whereby the trim strip is displaced upwardly of the lips and the spring means is compressed to provide a downward force on the floor channel, each of the panels being removable by displacing the panel upwardly to further compress the spring means and thereby release the lower end of the panel from the floor channel whereupon the panel is removed from the ceiling channel by first moving the lower end of the panel away from the floor channel and then lowering the panels so that the upper end of the panel is removed from the ceiling channel.
Claim 3
Dependent Claim
252 words
A demountable partition comprising: an upwardly-opening floor channel on a floor; a downwardly-opening ceiling channel affixed to the ceiling parallel to and above said floor channel, the depth of the ceiling channel being substantially greater than the depth of the floor channel and the ceiling channel having a pair of inwardly extending lips defining a slot; a trim strip engaged in the ceiling channel and having a width greater than the width of the slot; and spring means housed in the ceiling channel above the trim strip for biasing the trim stip into engagement with upper surfaces of the lips; and panels having a thickness slightly less than the width of the slot for sliding engagement in the ceiling channel between the lips, each of the panels having respective upper and lower ends engaged in the ceiling and floor channels, the upper ends of the panels being engaged against the underside of the trim strip whereby the trim strip is displaced upwardly of the lips and the spring means is compressed to provide a downward force on the floor channel, each of the panels being removable by displacing the panel upwardly to further compress the spring means and thereby release the lower end of the panel from the floor channel whereupon the panel is removed from the ceiling channel by first moving the lower end of the panel away from the floor channel and then lowering the panels so that the upper end of the panel is removed from the ceiling channel.
Claim 4
