Definitions

  • This invention relates to a paper-retaining mechanism and a document file incorporating such a mechanism.
  • lever-arch type file mechanisms a one-armed lever is pivotable to pivot a pair of arches relative to a pair of fixed posts to allow pieces of hole-punched paper to be retrieved from or inserted into the file mechanism, and for closing the posts and arches to form a pair of closed rings to retain the paper therein.
  • the pair of arches are joined by an intervening crank on which a roller attached to the lever travels during pivotal movement of the lever, to effect opening or closing of the pair of rings.
  • the lever is pivoted downwardly to close the ring pairs formed by the posts and arches and is pivoted upwardly to allow a spring leaf to pivot to thereby open the rings.
  • Such a conventional file mechanism is not convenient in use, in that when the lever is pivoted upwardly to open the rings, the lever is very close to or even touches one of the arches, such that it is not possible to have paper inserted into or retrieved from the arches.
  • a paper-retaining mechanism including a base, at least two post members fixedly engaged with said base, at least two arch members engaged with said base for pivotal movement relative to said post members; and a lever member pivotable relative to said base; wherein said arch members are joined with each other via a cranked rod for simultaneous movement; wherein said arch members are i pivotable between a closed position in which said arch members are in contact with said post members to form at least two closed rings and an open position in which said arch members are out of contact with said post members whereby said rings are open; and wherein said lever member is pivotable relative to said base between a first position in which said rings are closed and a second position in which said rings are open; characterized in that said lever member includes an actuating part which, when said lever member is pivoted from said first position to said second position, pivots said cranked rod away from said base to pivot said arch members to said open position.
  • a document file including a substrate engaged with a paper-retaining mechanism including a base, at least two post members fixedly engaged with said base, at least two arch members engaged with said base for pivotal movement relative to said post members; and a lever member pivotable relative to said base; wherein said arch members are joined with each other via a cranked rod for simultaneous movement; wherein said arch members are pivotable between a closed position in which said arch members are in contact with said post members to form at least two closed rings and an open position in which said arch members are out of contact with said post members whereby said rings are open; and wherein said lever member is pivotable relative to said base between a first position in which said rings are closed and a second position in which said rings are open; characterized in that said lever member includes an actuating part which, when said lever member is pivoted from said first position to said second position, pivots said cranked rod away from said base to pivot said arch members to said open position.

  • the mechanism 100 includes a generally planar base 102 to which two posts 104 are fixedly secured.
  • a pair of arches 106 are joined with each other via a cranked rod 108, with which they are integrally formed.
  • the arches 106 and the cranked rod 108 are thus movable simultaneously.
  • the cranked rod 108 is engaged with a pair of clamps 110 on and integrally formed with the base 102, so that the cranked rod 108 is pivotable relative to the base 102 and the posts 104 about an axis Ri-Ri close to the base 102.
  • the cranked rod 108 is pivotable to pivot the arches 106 (with which it is simultaneously movable) between a ring-closed position in which free ends 1 06a of the arches 106 contact and mate with free ends 104a of the posts 104 to form two closed rings (as shown in Figs.
  • a plate 112 which is integrally formed with the base 102, extends generally perpendicularly from the base 102.
  • a lever 114 is pivotally mounted by a rivet 116 to the plate 112 at a point adjacent the base 102.
  • the lever 114 has a hole 118 and the plate 112 has a hole 120 adjacent the base 102.
  • the rivet 116 is partly received through these two holes 118, 120 for pivotally mounting the lever 114 to the plate 112.
  • the lever 114 is pivotable relative to the base 102, the plate 112 and the posts 104 about an axis Si-Si which is perpendicular to the axis Ri-Ri.
  • the lever 114 has a planar body portion 122 integrally formed at one longitudinal end thereof with a planar thumb piece 124, and at an opposite longitudinal end thereof with a planar toe portion 126.
  • the thumb piece 124 is perpendicular to the body portion 122 and the toe portion 126 is also perpendicular to the body portion 122.
  • a roller 130 is mounted onto the body portion 122 by a rivet 132 such that the roller 130 is freely rotatable about an axis Ti-Ti which is parallel to the axis Si-Si.
  • Figs. 2 to 7 show the paper-retaining mechanism 100 in a configuration (called the "ring-closed configuration") in which the lever 114 is in its ring-closed position and the free ends 106a of the arches 106 contact and mate with the free ends 104a of the posts 104 to form two closed rings.
  • the roller 130 sits on and engages with a recess 134 (see Fig. 1) on an upper part of an upwardly bent portion 136 of the cranked rod 108, to thereby press the cranked rod 108 towards the base 102, so as to keep the arches 106 in the ring-closed position.
  • the roller 130 sits on and engages with a recess 138 (see Fig. 2) of a downwardly bent portion 140 of the cranked rod 108.
  • the radius of curvature of the recess 134 is smaller than that of the recess 138.
  • the engagement between the roller 130 of the lever 114 and the recess 138 limits the extent of the upward pivotal movement of the cranked rod 108 and that of the pivotal movement of the lever 114 in the direction indicated by the arrow W 1 .
  • any further pivotal movement in the direction of the arrow W 1 (which tends to bring about a further pivotal movement of the roller 130 in the same direction about the axis S 1 -S 1 ) will bring about a corresponding upward pivotal movement of the toe portion 126, which in turn tends to pivot the cranked rod 108 further upward, directly against the further pivotal movement of the roller 130.
  • the roller 130 is also pivoted about the axis S 1 -S 1 to engage with and press the recess 134 of the cranked rod 108 towards the base 102, so as to pivot the cranked rod 108 (and thus the arches 106) back to the ring-closed position as shown in Figs. 2 to 7.
  • the thumb piece 124 is always between the two rings formed by the posts 104 and arches 106, whether the lever 114 is in its ring-closed position or ring-open position, or during its pivotal movement between these two positions.
  • the pivoting axis S 1 -S 1 of the lever 114 is between the roller 130 and the toe portion 126.
  • Fig. 13 Components of a paper-retaining mechanism according to a second embodiment of the present invention are shown in Fig. 13, with the mechanism generally designated as 200. It can be seen that the construction of the mechanism 200 is similar to but simpler than that of the mechanism 100 discussed above.
  • the mechanism 200 includes a generally planar base 202 to which two posts 204 are fixedly secured.
  • a pair of arches 206 are joined with each other via a cranked rod 208, with which they are integrally formed.
  • the arches 206 and the cranked rod 208 are thus movable simultaneously with one another.
  • the cranked rod 208 is engaged with a pair of clamps 210 on and integrally formed with the base 202, so that the cranked rod 208 is pivotable relative to the base 202 and the posts 204 about an axis R 2 -R 2 close to the base 202.
  • the cranked rod 208 is pivotable to pivot the arches 206 (with which it is simultaneously movable) between a ring-closed position in which free ends 206a of the arches 206 contact and mate with free ends 204a of the posts 204 to form two closed rings (as shown in Figs.
  • a plate 212 which is integrally formed with the base 202, extends upwardly away from the base 202.
  • a lever 214 is pivotally mounted by a rivet 216 to the plate 212 at a point adjacent the base 202.
  • the lever 214 has a hole 218 and the plate 212 has a hole 220 adjacent the base 202.
  • the rivet 216 is received through these two holes 218, 220 to pivotally mount the lever 214 to the plate 212.
  • the lever 214 is pivotable relative to the base 202, the plate 212 and the posts 204 about a common longitudinal axis of the rivet 216, the hole 220, and the hole 218, which is perpendicular to the axis R 2 -R 2 .
  • the lever 214 is made of a plasties material, and has a body portion 222 with two longitudinal ends. One longitudinal end of the body portion 222 serves as a thumb piece 224, and an opposite longitudinal end of the body portion 222 is a toe portion 226 with a wall portion 227. The toe portion 226 and the wall portion 227 are generally perpendicular to each other.
  • the lever 214, including the body portion 222, the thumb piece 224, the toe portion 226 and the wall portion 227, is integrally made in one piece of the plastics material, and all such parts are thus movable simultaneously with one another.
  • first recess 234 with a first recess 234, and a downwardly bent portion 240 of the cranked rod 208 adjacent to the upwardly bent portion 236 has a second recess 238.
  • the radius of curvature of the first recess 234 is smaller than that of the second recess 238.
  • Figs. 14 to 20 show the mechanism 200 in a configuration (called the "ring-closed configuration") in which the lever 214 is in its ring-closed position and the free ends 206a of the arches 206 contact and mate with the free ends 204a of the posts 204 to form two closed rings.
  • a curved protrusion 242 of the lever 214 sits on and engages with the first recess 234 on an upper side of the upwardly bent portion 236 of the cranked rod 208, to thereby press the cranked rod 208 towards the base 202, so as to keep the arches 206 in the ring-closed position.
  • the lever 214 When the lever 214 is pivoted (e.g. manually by a user) relative to the base 202 and the posts 204 about the longitudinal axis of the hole 220 in the direction indicated by the arrow W 2 (see Fig. 14) and away from its ring-closed position, the protrusion 242 is moved away from engagement with the recess 234 of the cranked rod 208.
  • the toe portion 226 is pivoted, again about the longitudinal axis of the hole 220 of the plate 212, and in the same direction indicated by the arrow W 2 , to engage with and act on the cranked rod 208 from below, to cause the cranked rod 208 to pivot about the axis R 2 -R 2 and away from the base 202.
  • the protrusion 242 sits on and engages with a recess 238 (see Fig. 14) of a downwardly bent portion 240 of the cranked rod 208.
  • the lever 214 is already in the ring-open position as shown in Figs.
  • any further pivotal movement in the direction of the arrow W 2 (which tends to bring about a further pivotal movement of the lever 214 the same direction about the longitudinal axis of the hole 220 of the plate 212) will bring about a corresponding upward pivotal movement of the toe portion 226, which in turn tends to pivot the cranked rod 208 further upward, directly against the further pivotal movement of the protrusion 242 of the lever 214. Therefore, there cannot be any pivotal movement of the lever 214 in the direction indicated by the arrow W 2 beyond the position shown in Figs. 21 to 26, nor can there be any further upward pivotal movement of the cranked rod 208 beyond the position shown in Figs. 21 to 26.
  • the wall portion 227 is raised from its lower position (as shown in Figs. 14 and 19) in which it is close to the base 202 to its upper position (as shown in Figs. 21 and 25) in which it is raised from the base 202, to come into contact with the upwardly pivoted cranked rod 208.
  • Figs. 21 to 25 it can be seen that when the mechanism 200 is in its ring-open configuration (in which the arches 206 are out of contact and out of engagement with the posts 204), the wall portion 227 of the lever 214 is in its upper position, and a side of the wall portion 227 facing the plate 212 contacts a side of the cranked rod 208 facing the arches 206. It is found in practice that, in the absence of the wall portion 227, it is sometimes possible to forcibly pivot the cranked rod 208 out of engagement with the toe portion 226, for example by forcibly pulling the arches 206 further away from the posts 204, thus causing damage to the mechanism 200.
  • the wall portion 227 therefore assists in limiting the extent of pivotal movement of the cranked rod 208 away from the base 202.
  • the protrusion 242 is also pivoted about the longitudinal axis of the hole 220 of the plate 212 to engage with, act on and press the recess 234 of the cranked rod 208 towards the base 202, so as to pivot the cranked rod 208 (and thus the arches 206) back to the ring-closed position as shown in Figs. 14 to 20.
  • the longitudinal end of the lever 214 opposite to the protrusion 242 and the toe portion 226 is always between the two rings formed by the posts 204 and arches 206, whether the lever 214 is in its ring-closed position or ring-open position, or during its pivotal movement between these two positions. It can also be seen that the pivoting axis of the lever 214 is between the protrusion 242 on the one hand and the toe portion 226 and the wall portion 227 on the other hand.
  • both mechanisms 100, 200 are of a spring-less structure.
  • Both the mechanisms 100, 200 may be secured, e.g. by screws or rivets or other securing means, to a substrate, e.g. a cover made of cardboard, plastics, metal or a combination thereof, to form a document file, e.g. a box file or document holder.

Abstract

Mécanisme de retenue de papier (100, 200), comprenant une base (102, 202), deux montants (104, 204) fixés à la base, deux arches (106, 206) engagées avec la base pour exécuter un mouvement pivotant par rapport aux montants, et un levier (114, 214) pouvant pivoter par rapport à la base. Les arches sont jointes l'une à l'autre par l'intermédiaire d'une manivelle (108, 208) pour exécuter un mouvement simultané, et peuvent pivoter entre une position fermée, dans laquelle les arches sont en contact avec les montants pour former deux anneaux fermés, et une position ouverte, dans laquelle les arches ne sont pas en contact avec les montants, avec comme conséquence que les anneaux sont ouverts. Le levier peut pivoter par rapport à la base entre une première position, dans laquelle les anneaux sont fermés, et une deuxième position, dans laquelle les anneaux sont ouverts, et le levier comprend une partie de patte (126, 226) qui fait pivoter la manivelle à l'écart de la base de manière à faire pivoter les arches dans la position ouverte lorsque le levier pivote de la première position vers la deuxième position.
