Abstract: A ring binder to be fixed to an article has a support for mounting a plurality of ring members thereon and a control member for opening and closing the ring binder. The support has a pair of support members pivotally supported by a holder joining the outer edges of the support members together, whereby the inner edges of the support members move away from each other on pivoting. The holder cooperates with the control member in order to support the support members. The ring binder may also include one or more securing elements for holding the support members by extending across from the outer edges of the support members and cooperating with the control member, and fixing elements below and connected to the support members.

Abstract: A ring binder to be fixed to an article includes a support for mounting a plurality of ring members thereon, with a control member to open and close the ring binder. The support is cooperable solely with the control member to lock the ring members in closed position, the support being provided with a hooked portion to lock the ring members in closed position. In another embodiment, the support has a pair of support members disengageable during opening of the ring binder, one support member having at least one engagement member directly cooperable with the other support member during closing of the ring binder. The ring binder further includes a control member movable along a sloped portion of the under surface of the support to cause the support to pivot and thereby open the ring members, the sloped portion being provided on the underneath of at least one of the support members, approximately along the centerline.

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.

Abstract: A ring binder to be fixed to an article includes supports for mounting a plurality of ring members thereon, and a control member movable to open and lock and to close and lock the ring members, each in one operation, the controlling member including a crossbar member extending to outer edge regions of the support means. In another embodiment, the control members are slidably movable to lock the ring members in open position and in closed position, and the support comprises a pair of support members supported by holding elements joining outer edges of the pair of support members together, the holding elements cooperating with the control member means in order to support the supports.
