Description

Ring Binder Mechanism

A first aspect of the invention relates to a ring binder mechanism ready to be secured to an object, such as a cover, and a second aspect of the invention also relates to a ring binder mechanism for securing the ring binder mechanism to the object. Fixtures.

Conventional ring binder mechanisms include a substantially rigid upper cover sheet supporting a pair of sheets. A plurality of semicircular rings are fixedly connected to each of the sheets. The pair of sheets can pivot relative to each other from a first relative position to a second relative position, and in the first relative position, the angle between the upper surfaces of the pair of sheets is less than 180°, so that each pair of halves The rings are closed to keep the loose-leaf paper; and in the second relative position, the angle between the upper surfaces of the pair of sheets is greater than 180°, so that each pair of semi-circular rings is opened so that the loose-leaf paper can be inserted Or take it out of the semicircle. Such conventional ring binder mechanisms are typically secured to the cover with a pair of rivets, each rivet adjacent one longitudinal end of the ring binder mechanism. Each such rivet generally includes a post having a head engaging the upper cover sheet of the ring binder mechanism and prongs which penetrate the cover, and thereby secure the ring binder to the cover.

In order to strengthen the joint between the rivet and the cover, various methods and arrangements have been devised. One such improvement consists in incorporating an anchor in the rivet, the anchor having an abutment face which abuts the cover when the rivet is secured to the cover. With this arrangement, the ring binder mechanism can resist a relatively large lateral (ie, transverse to the longitudinal axis of the ring binder mechanism) pulling force.

To further enhance the engagement between the rivet (and thus the ring binder mechanism) and the cover, the rivet is dimensioned such that when the rivet is properly engaged with the upper cover sheet, the lateral sides of the rivet extend beyond the lateral sides of the upper cover sheet side. Although this arrangement achieves the intended purpose of strengthening the joint between the rivet and the cover, it has been found in practice that, during assembly, accidental excessive force may be applied to the lateral sides of the rivet, thereby damaging the rivet. Or bend rivets.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a ring binder mechanism and a rivet that overcomes the above disadvantages, or at least provides the business and public with a useful alternative.

A first embodiment of a ring binder mechanism according to the present invention is shown generally at 10 in FIGS. 1 to 3 . The ring binder mechanism 10 includes an upper curved housing 12 supporting a pair of blades 14 . Three semicircular rings 16 are fixedly connected to each sheet 14 . A lever 18 is provided at each longitudinal end of the ring binder mechanism.

When the pair of sheet bodies 14 are in relative positions as shown in FIGS. Each semicircle is closed. The pair of levers 18 can be pivoted outwardly away from each other, thereby pivoting the sheet 14 in a conventional manner until the pair of sheet 14 is at the second point where the angle between the upper surfaces of the two sheets 14 is greater than 180°. The relative position is still, and each semicircular ring 16 on the sheet body 14 is opened. By pushing the pair of semi-circular rings 16 together or pivoting the pair of levers 18 towards each other, the flaps 14 can be returned to the relative positions shown in FIGS. 1 to 3 .

The ring binder mechanism 10 also includes a pair of rivets 20 each adjacent to one of the two longitudinal ends of the ring binder mechanism 20 . The rivet 20 includes a substantially flat rectangular anchor piece 22 with a central hollow cylinder 24 extending vertically thereon. The cylinder has an upper end 26 which is deformable to engage an annular groove 28 of the curved housing 12 . A plurality of claws 30 protrude from the lower surface and two sides of the anchor piece 22 . The prongs 30 can penetrate a cover 32, which can be made of cardboard or PVC (polyvinyl chloride). The anchor piece 22, the column body 24 and the claw 30 are all formed as a whole.

As shown more clearly in FIGS. 4A and 4B , the rivet 20 includes a plurality of parallel ridges/grooves 34 . In the rivet 20 shown in FIGS. 4A and 4B , the ridges/grooves 34 form protrusions (ridges) on the upper, larger surface 36 of the anchor plate 20 and recesses on the lower, larger surface 38 of the anchor plate 20. (groove). The ridges/grooves 34 may also be configured to form recesses on the upper larger surface 36 of the anchor plate 20 and protrusions on the lower larger surface 38 . The ridges/grooves 34 may also be arranged such that one or more of them form a protrusion on the upper larger surface 36 of the anchor plate 20 and one or more of them form a recess on the lower larger surface 38 . It can also be seen that the anchor plate 20 includes a pair of longer sides and a pair of shorter sides. The two outer ridges/grooves 34 are parallel to the pair of longer sides, and the length of each of the two outer ridges/grooves 34 is greater than 50% of the length of each longer side. As shown in FIGS. 1 and 2 , the ridge/groove 34 is transverse to the longitudinal axis of the curved shell 12 when the rivet 20 is properly engaged with the curved shell 12 .

A second embodiment of a ring binder mechanism according to the present invention is shown generally at 100 in FIGS. 5-7. As with the ring binder mechanism shown in FIGS. 1 to 3, the ring binder mechanism 100 includes an upper curved housing 102 that supports a pair of sheets 104 to which three pairs of semi-circular rings 106 are fixedly connected. 104 on. A pair of operating rods 108 are provided at the two longitudinal ends of the ring binder mechanism 100 to control the opening and closing of the three pairs of semicircular rings 106 . Adjacent each longitudinal end of the ring binder mechanism 100 is a rivet 110 .

As can be seen more clearly in FIGS. 8A and 8B , each rivet 110 includes an anchor plate 112 having an upper major surface 114 and a lower major surface 116 . Extending perpendicularly from the upper larger surface 114 is a central hollow cylinder 118 having an open end 120 which is deformable to engage the annular groove 122 of the upper curved housing 102 . The anchor 112 includes a pair of longer sides 124 and a pair of shorter sides 126 . Extending from the lower larger surface 114 of the anchor piece 112 along the length of the pair of shorter sides 126 are a plurality of prongs 128 that can penetrate the cover 130 to secure the ring binder mechanism 100 to the cover 130 .

On the upper major surface 114 and the lower major surface 116 of the anchor plate 112 there are a pair of ridges/grooves 132 . In the rivet 110 shown in FIGS. 8A and 8B , the pair of ridges/grooves 132 is a protrusion (ridge) formed on the upper larger surface 114 of the anchor piece 112 and a protrusion (ridge) on the lower larger surface 116 of the anchor piece 112. Recesses (grooves) are formed. The ridges/grooves 132 may also be configured to form recesses on the upper larger surface 114 of the anchor plate 112 and protrusions on the lower larger surface 116 . The ridges/grooves 132 can also be configured to either form a protrusion on the upper larger surface 114 of the anchor plate 112 or to form a recess on the lower larger surface 116 .

The two ridges/grooves 132 are parallel to each other and both are parallel to the pair of longer sides 124 . The length of each of the two ridges/grooves 132 is greater than 50% of the length of each longer side 124 . As shown in FIG. 7 , the pair of ridges/grooves 132 are transverse to the longitudinal axis of the shell 102 when the rivets 110 are properly engaged with the upper curved shell 102 .

It can be understood that the above are only examples of the implementation of the present invention, and further modifications and/or changes can be made without departing from the scope of the spirit of the present invention.
