A binding mechanism assembly 18 is configured to be installed onto a support structure 14. The binding mechanism assembly includes a binding mechanism 34 having at least one securing structure 42 configured to be coupled to a sheet for securing the sheet to the binding mechanism, and a base 38 configured to be coupled to the binding mechanism and movable between a first configuration (figure 4), in which a portion of the base defines a first dimension, and a second configuration (figure 5), in which the portion of the base defines a second dimension larger than the first dimension. The base can be moved from the first configuration to the second configuration to install the base onto the support structure. The binding mechanism is preferably a lever arch binding mechanism and may be releasably coupled to the base. |
