Abstract
A magnetic clip comprising a combined magnetic member/second firm plate unit (34) lever, and a second flexible film (27) which is wrapped around and attached to said combined magnetic member/second firm plate unit lever, and an opposing ferric armature member (22) lever, and a folded flexible attachment means (26) to which said opposing levers are adhered under said fold. The lower proximal edge of said magnetic member serves as a fulcrum (44) about which said two levers can be pivoted by the operator's fingers of only one hand which can raise or lower portions (52), (56), (54), and (58) thereby causing the leading edges of said clip to open or close as needed to secure or release said clip to or from a sheet (30). Closed life size view (84).
Claims4
A magnetic bookmark releasably securable to a selected position on a page, comprising:
- a planar magnetic member (20);
- a planar ferric armature member (22) randomly juxtaposed with respect to longitudinal orientation and magnetically attached to said magnetic member;
- means for allowing said juxtaposed members to pivotably separate at one side in response to application of a squeezing force at the opposite side of said members;
- attachment means (26) hingedly connecting said magnetic member and said armature member;
- said means for allowing said juxtaposed members to pivotably sepatare including
- a firm plate (24) secured to said magnetic member (20) on the side opposite from said armature member (22), said armature member and said firm plate each being of a like dimension and greater than the dimension of said magnetic member, to overlap and provide a fulcrum (44) between said armature member and said firm plate, and
- a flexible film paper-guide (29) covering an inner side of said magnetic member (20), and wrapped over and covering at least a portion of an outer side of said firm plate (24).
