ABSTRACT:

This invention relates to a ring binder and, in particular, a ring binder adapted to be secured by at least one rivet to a base member.
Conventionally, a ring binder is securable to a cover by rivets having a head portion engageable with the cover and a tail portion which is deformable, e.g. by punching, to engage a barrel secured to an upper plate of the ring binder.
A disadvantage associated with such a conventional ring binder is that the assembling process is both laborious and prone to error. In the first place, it is necessary to provide the assemblers with rivets properly sized and shaped to fit both the barrels and the corresponding holes in the cover. The assemblers have to secure the ring binder to the cover by first inserting the rivet through the cover, then through the barrel in the ring binder and then to deform the tail of the rivet, e.g. by punching, to engage the upper plate of the ring binder.
It is therefore an object of the present invention to provide a ring binder in which the aforesaid shortcomings are mitigated. It is also a further object of the present invention to provide a rivet to mitigate the aforesaid problems.
According to a first aspect of the present invention, there is provided a ring binder adapted to be secured to a base member the ring binder including a substantially rigid integral upper structure with a longitudinal axis; a pivotable lower structure supported by said upper structure; a plurality of ring members mounted to said lower structure; and at least one integral securing means for securing said ring binder to said base member, said at least one securing means including an engagement portion in direct engagement with the upper structure for attaching said securing means to said upper structure; an abutment portion adapted to abut said base member when said ring binder is secured to said base member; and a plurality of securing elements for securing the ring binder to the base member; said abutment portion including at least one major surface; and said abutment portion including at least one side edge from which a ridge member extends away from said major surface.
According to a second aspect of the present invention, there is provided a rivet for securing a ring binder to a base member, said rivet including an engagement portion adapted to be in direct engagement with said ring binder; an abutment portion for abutting said base member when said ring binder is secured to said base member; and a plurality of securing elements for securing the ring binder to the base member; said abutment portion including at least one major surface; and said abutment portion including at least one side edge from which a ridge member extends away from said major surface.
