Abstract: A restraining device for a loose leaf binder comprises restraining members each having a substantially rigid spacing portion with cover mounting and coupling portions at respective opposite ends. The cover mounting portions extend perpendicularly from respective spacing portions and comprise respective clips for gripping respective free edge portions of respective cover members releasably to mount the restraining members thereon with the respective spacing portions extending perpendicularly from their respective cover members across the binder towards each other. The coupling portions have complementary latching means inter-engageable with a snap action by closing movement of the cover members so that the restraining members bridge the free edges of the cover members maintaining them spaced apart in parallel relation irrespective of the height of papers stacked therebetween and are releasable by application of finger pressure.

Abstract: A file cover restraining device includes a strut-like restraining member for bridging the inside surfaces of the file cover members and constructed from first and second elongate strut members interconnected for relative longitudinal sliding movement thereby to adjust a length of the restraining member to match the separation of the cover members and retained in a selected position by manually operable latches. The first strut member has a hook on an end thereof remote from the second strut member, a first cover mounting portion being pivotally connected to an end of the second strut member remote from the first strut member and having adhesive for attachment to an inside surface of one cover member and, a second cover mounting portion has adhesive for attachment to an inside surface of the other cover member and is formed with an eye. The hook and eye are releasably engaged by pivotal movement of the restraining member toward the spine.

Abstract: A binder cover restraining member comprises a central, one piece, restraining strut portion and cover mounting portions formed by inner and outer retention shoulders held spaced apart in opposed relation by a narrow neck portion, at respective opposite ends thereof. The cover members are formed with pairs of aligned keyhole mounting slots extending adjacent free edges thereof remote from the spine. Endmost retention shoulders can be pushed from inside the cover members through the wide slot portions and along the slots into the narrow retention portions so that inner and endmost retention shoulders engage respective opposite surfaces of the cover members retaining respective neck portions extending therethrough so that the strut extends between the inside surfaces of respect cover members to retain them in closed condition spaced apart in parallel relation.
