- Fig.1-12 show a ring binder mechanism 100 according to a first embodiment of the invention.
- the ring binder mechanism 100 generally comprises a housing 101, two rings 103, two hinge plates 105 and a control means 107.
- the control means 107 is supported by the housing 101, and the rings 103 are mounted to the hinge plates 105. As described hereafter, the control means 107 may rotate relative to the housing to close and lock the ring binder mechanism 100 for retaining loose-leaf pages, or to open the ring binder mechanism 100 for adding or removing loose-leaf pages from the ring 103.
- the housing 101 is elongated with a symmetrically, roughly arch-shaped cross section.
- a flat top portion 109 is formed at the center of the housing top.

- the other longitudinal edge portion 111 of the housing 101 and two longitudinal ends 113 form respectively with the flat extensions 111b, 113a, 113b extending in the same plane.
- the other longitudinal edge portion 111 with the flat extensions 111b is provided along the longitudinal direction with a plurality of protrusions 115 projecting towards the inside of the housing.
- the flat extensions extending in the same plane may be formed only at the two longitudinal ends 113 of the housing respectively.
- the other longitudinal edge portion 111 is also slightly bent downwards to form the bend under rim.
- the ring binder mechanism 100 may be fixed to the cover of a file or notebook by such fasteners as rivets through a hole in the housing.
- fasteners as rivets through a hole in the housing.
- the housing 101 may be made from metal or other suitable material as long as the material has enough rigidity to ensure the stably mounting of the components of the ring binder mechanism 100, and has enough resilience to allow it to function as a spring.
- An opening 117 for receiving the control means 107 is formed on the flat top portion 109 of the housing 101, and projections 119 with aligned holes are formed at both sides of the opening 117.
- the control means 107 may be pivotally mounted to the housing 101 by a pivot shaft 121 extending through the holes in the control means 107 and the projections 119.
- the opening 107 and projections 119 are formed at the same time by punching and cutting the housing 101.
- a plurality of reinforcing ribs across the housing 101 may be formed on the housing 101, and preferably the reinforcing ribs may be formed integrally on the housing 101 by punching.
- pairs of cutouts 123 opposite to each other are provided between the two longitudinal edge portions 111 and the two longitudinal ends 113 of the housing 101 respectively for receiving the rings 103. It should be understood that the housing with various shapes such as an asymmetric housing and the housing with various reference numerals and shapes of opening or cutouts fall within the scope of the invention.
- Each of the rings 103 comprises ring members 103a and 103b mounted respectively at two hinge plates 105. With the bend under rim 111a and the plurality of protrusions 115, the two hinge plates 105 are supported by the housing 101 to pivot to move the ring members 103a and 103b between a closed position and an open position.
- the ring members 103a and 103b have a cross section of circular shape, and may be made from suitable metals such as steel.
- the ring member 103a and 103b may form a substantially continuous, closed, "D"-shaped loop ring or loop for retaining loose-leaf pages and for allowing loose-leaf pages to move along the ring 103 from one ring member to the other.
- the ring members form a discontinuous, open loop suitable for adding or removing pages.
- both of the ring members may move, a mechanism having one movable ring member and one fixed ring member also falls within the scope of the invention.
- a mechanism with more than two rings and with the rings that form other shapes e.g., both of the ring members have a semicircular shape) when closed also falls within the scope of the invention.
- Each of the hinge plates 105 is a thin and elongate sheet with a length slightly shorter than the housing 101, and has an inner longitudinal edge 125, an outer longitudinal edge 127 and two longitudinal ends.
- the two hinge plates 105 interconnect with each other along their inner longitudinal edges in parallel arrangement to form a central hinge with a pivot axis. This may be achieved in a well-known manner.
- the interconnected hinge plates 105 are disposed within the housing 101 such that the outer longitudinal edge 127 of each of the hinge plates fits loosely between the top of the housing 101 and the corresponding bend under rim 111a and a plurality of protrusions 115 respectively. In this structure, although the hinge plates 105 are disposed within the housing 101, the hinge plates 105 may pivot about the pivot axis.
- the pivot axis moves upwards (i.e., moves towards the flat top portion 109 of the housing 101), as shown in Fig.12.
- the pivot axis moves downwards (i.e., moves away from the flat top portion 109 of the housing 101), as shown in Fig.8.
- the hinge plates 105 are designed such that the angle between the outer surfaces of two hinge plates 105 (i.e., the surfaces facing away from the flat top portion 109 of the housing 101) is always less than 180° when the hinge plates 105 pivot within the housing 101, and the pivot axis never moves to a position lower than the coplanar position of the two hinge plates 105 (i.e., the position that the angle between the outer surfaces of the two hinge plates 105 is equal to 180°). Therefore, the resilience of the housing 101 always moves the pivot axis of the hinge plates 105 upwards and pivots the hinge plates 105 to open the ring members 103a and 103b instead of closing the ring members 103a and 103b.
- the angle between the outer surfaces of the two hinge plates may be more than 180° when the ring binder mechanism closes.
- the resilience of the housing moves the pivot axis of the hinge plates 105 downwards and pivots the hinge plates 105 to close the ring members 103a and 103b instead of opening the ring members 103a and 103b.
- the hinge plates may be designed such that they pivot upwards and downwards to allow the pivot axis to pass through the coplanar position (180°) of the hinge plates.
- the housing 101 supports the control means 107 to allow it to rotate relative to the housing 101.
- the control means 107 of this embodiment comprises a control lever and a cam portion 131.
- the control lever 129 and the cam portion 131 are formed integrally with each other by bending a metal sheet. However, they may be formed separately and then assembled together.
- the cam portion 131 is defined by two separated cam sheets 133.
- a correspondingly shaped pad block 135 is fitted between the two separated cam sheets 133.
- the pad block 135 is fixed in the space between the two separated cam sheets 133 by two pins 137.
- the pad block 135 is preferably made from plastics.
- the control means 107 is pivotally mounted to the housing 101 by the pivot shaft 121 passing through the cam portion 131 of the control means 107 and the holes of the projections 119 of the housing 101.
- the control means 107 may have other shapes.
- the control means may be any suitable known structures that apply force to the hinge plates from the bottom side of the hinge plates (i.e., from outer surface of the hinge plates), such as the control means disclosed in the Chinese Patent Application No.200510055025.2 .
- each of the ring members 103a and 103b of the ring binder mechanism 100 according to the invention does not locate on the same plane.
- Each of the ring members 103a and 103b of the ring binder mechanism 100 according to the invention comprises respectively ring sections 103a' and 103b' for retaining loose-leaf pages, and ring sections 103a" and 103b" for mounting to the hinge plates 105.

- the ring sections 103a" and 103b" for mounting to the hinge plates 105 are generally straight, and form an inside angle of less than 90° with respect to the plane on which the ring sections 103a' and 103b'for retaining loose-leaf pages locate.
- the ring sections 103a" and 103b" for mounting to the hinge plates 105 are generally "L" shape, and form an inside angle of about 90° with respect to the plane on which the ring sections 103a' and 103b' for retaining loose-leaf pages locate.
- the ring binder mechanism 100 has more than two rings 103, two sections of each of ring members 103a and 103b of the rings 103 only near two longitudinal ends of the housing do not locate on the same plane. It should be noted that the ring binder mechanism with one of two ring members of one ring movably mounted to the hinge plate, and the other fixedly mounted to the housing also falls within the scope of the invention.
- the control means 107 may move selectively the ring binder mechanism 100 to the closed and locked position (as shown in Fig.1-8) and the open position (as shown in Fig.10-12).
- the control lever 129 of the control means of the ring binder mechanism as shown in Fig.10 is rotated down towards the housing such that the acting end of the cam portion 131 of the control means press down against two hinge plates 105.
- the pivot axis of the hinge plates 105 moves downwards away from the flat top portion 109 of the housing such that the ring members 103a and 103b mounted to the hinge plates 105 join together with the pivoting motion of the hinge plates to form a closed loop for retaining loose-leaf pages.
- the cam portion 131 of the control means 107 still keeps pressing against the hinge plates 105, the ring members 103a and 103b join together and can not separate with each other.
- the hinge plates 105 is positioned such that the angle between their outer surfaces is at the maximum value but less than 180° (i.e., the pivot axis of the hinge plates locates above the coplanar position (180°)), as shown in Fig.8.
- the control lever 129 of the control means of the ring binder mechanism as shown in Fig.6 is rotated upwards away from the housing such that the cam portion 131 of the control means separates from the two hinge plates 105.
- the pivot axis of the hinge plates 105 moves up towards the flat top portion 109 of the housing such that the ring members 103a and 103b mounted to the hinge plates 105 separate with each other with the pivoting motion of the hinge plates.
- the resilience of the housing 101 keeps the ring members 103a and 103b in the open state for adding or removing loose-leaf pages.
- the hinge plates 105 are positioned such that the angle between their outer surfaces is at the minimum value, as shown in Fig.12.
- each of the ring members 103a and 103b comprises the ring sections 103a' and 103b' for retaining loose-leaf pages and the ring sections 103a" and 103b" for mounting to the hinge plates 105 respectively, and the ring section 103a" and 103b" are mounted to the hinge plates 105 with an inside angle of no more than 90° with respect to the plane on which the ring sections 103a' and 103b'for retaining loose-leaf pages locate, the length of the hinge plates 105 and thus the length of the elongate housing 101 may be remarkably decreased by properly increasing the length of the ring sections 103a" and 103b" for mounting to the hinge plates 105 when the length between the rings 103 at two longitudinal ends of the housing is constant. As a result, the materials used for producing the hinge plates and the elongate housing may be decreased greatly such that the costs for production, package and shipment of the ring binder mechanism will be lowered remarkably.

- the spring 239 is fitted onto the bottom of two hinge plates 205 for driving the hinge plates 205 to pivot so as to open the ring members 203a and 203b.
- the spring 239 is made from a metal wire with a circular cross-section, and formed as a polygonal shape with an open end 243 and a closed end 245.

- the open end 243 of the spring 239 comprises two free distal ends which are formed by bending twice respectively, in which the first bending is to bend the metal wire upwards at about 90° and the second bending is to bend the bent distal ends outwards at about 90°.
- Two free distal ends may be detachably fitted into the notches 241 on the other one of the interconnected hinge plates 205.
- the main portions 247 in the middle of the spring 239 protrude upwards in a generally arcuate shape. When the spring 239 is fitted into the two hinge plates 205, the main portions 247 in the middle of the spring 239 locate substantially below and against the interconnected hinge plates 205.
- the spring 239 is relatively slack when the hinge plates 205 are positioned such that the ring member 203a and 203b open.
- the main portions 247 in the middle of the spring 239 which protrude upwards in a generally arcuate shape abut against the hinge plates 205 such that the angle between the outer surfaces of the hinge plates 205 is less than 180° (i.e., the pivot axis of the hinge plates locates above the coplanar position (180°) of the hinge plates 205).
- the control lever 229 of the control means of the ring binder mechanism as shown in Fig.17 is rotated down towards the housing such that the acting end of the cam portion 231 of the control means 207 presses down against two hinge plates 205.
- the pivot axis of the hinge plates 205 moves down away from the flat top portion 209 of the housing and pass through the coplanar position (180°) of the hinge plates 205, such that the ring members 203a and 203b mounted to the hinge plates 205 join together with the pivoting motion of the hinge plates to form a closed loop for retaining loose-leaf pages.
- the spring 239 is biased properly to flatten the arcuate main portions 247.
- the control lever 229 of the control means 207 of the ring binder mechanism 200 as shown in Fig.14 is rotated upwards away from the housing such that the cam portion 231 of the control means separates from the two hinge plates 205.
- the biased spring 239 restores to its original shape and drives automatically the hinge plates 205 to pivot upwards through the coplanar position (180°) to open the ring members 203a and 203b.
- the spring 239 drives the hinge plates 205 to pivot so as to open the ring member 203a and 203b and to keep the opened ring members 203a and 203b at the separated state. Therefore, the spring 239 has the same function as the resilience of the housing.
- An advantageous effect of the mechanism 200 is that it is possible to decrease or eliminate the resilience of the housing and to apply force to the hinge plates 205 only by the spring 239. This allows the pivoting downwards of the hinge plates 205 and passing through the coplanar position (180°) more easily, thereby facilitating the closing of the ring binder mechanism 200. Furthermore, it is possible to open the ring binder mechanism without any manually operating the ring members.
- Fig.19-23 show the ring binder mechanism 300 according to a third embodiment of the invention.
- Components of the ring binder mechanism 300 of the third embodiment corresponding to components of the ring binder mechanism 100 of the first embodiment are represented by the same reference numerals, plus "200". The detailed description of the same structures in the third embodiment as those in the first embodiment will be omitted.
- the ring binder mechanism 300 according to the third embodiment is substantially similar to the ring binder mechanism 100 according to the first embodiment except that the structure of the ring members has a little difference between them.
- the free end of the ring member 103a prevents the control lever 129 of the control means 107 from rotating from one end of housing to the other end due to its overlength, i.e., the rotation position of the control lever 129 is limited so that it is inconvenient to add or remove loose-leaf pages.
- the shape and size of the free ends of the ring member 303a and 303b are designed to allow the control lever 329 of the control means 307 to rotate from one end of the housing 301 to the other end of the housing 301, thereby facilitating adding or removing loose-leaf pages.
- Fig.24-38 show the ring binder mechanism 400 according to a fourth embodiment of the invention.

- the ring binder mechanism 400 according to the fourth embodiment is substantially similar to the ring binder mechanism 100 according to the first embodiment except that the structure of the hinge plates has a little difference between them. As shown in Fig.9, the widths of two hinge plates 105 of the ring binder mechanism 100 according to the first embodiment are equal to each other, as shown in Fig.8 and Fig.12.
- the hinge plates 105 with equal width move in a relatively small range, which limits the opening distance between the free ends of the ring member 103a and 103b.
- the widths of the two hinge plates 405 are designed such that one hinge plate is wide and the other hinge plate is narrow.
- the angle range ⁇ A of movement of the narrow hinge plate 405 is lager than the angle range ⁇ B of movement of the wide hinge plate 405.
- the ring members attached to the narrow hinge plate 405 may open at a larger range with moving of the narrow hinge plate such that the opening distance between the free ends of the ring members becomes larger at the open position for adding or removing easily loose-leaf pages.
- the long ring member 403a is attached to the narrow hinge plate 405 while the short ring member 403b is attached to the wide hinge plate 405.
- the housing 401 may have a symmetric shape, or an asymmetric shape as shown in Fig.38.
- a ring binder mechanism in which the ring members 403a' and 403b' for retaining loose-leaf pages and the ring members 403a" and 403b" for mounting to the hinge plates 405 locate on the same plane and mount to the hinge plates perpendicularly to the longitudinal direction of the hinge plates also falls within the scope of the invention.
