ABSTRACT:
A ring binder to be fixed to an article includes a support for mounting a plurality of rings thereon. The ring binder has an exposed upper surface to which the rings are mounted, the surface being defined by an upper surface of the support. A control member opens and closes the binder. A securement member which holds the support and secures the support to an article is situated below the support in regions of limited longitudinal extent adjacent opposite ends of the binder. The control member acts at a first location, on an undersurface of the support, to open the binder, and at a second location, situated at an end region of the binder, to close the binder, the first and second locations being at different locations along the length of the binder. In another embodiment, inner edges of the support members are arranged to engage each other on closing of the binder and to disengage on opening of the binder.
