Abstract
A ring binder mechanism that retains loose-leaf pages and has ring members that readily lock together, preventing accidental loss of pages. The mechanism comprises a housing that supports two hinge plates for loose pivoting motion, bringing the ring members to either an open position or a closed position. The mechanism further comprises a control structure, which includes an actuating lever pivotally mounted on the housing. The actuating lever moves a travel bar and its locking elements for controlling the pivoting motion of the hinge plates. When the ring members are closed, the locking elements block the hinge plates from pivoting to open the ring members. In addition, a spring is attached to the travel bar for automatically biasing the travel bar and locking elements to the locked position when the ring members close.

Technical field
The present invention relates to a kind of circular ring loose-leaf binder mechanism that is used for fixing loose leaf paper, especially relate to a kind of being used to open and close annular element and make it sealed reliably improved mechanism.
Background technology
In the prior art, the annular mechanism for loose-leaf binder of standard will be fixed in a file or the notebook such as the loose leaf paper of punching paper or the like.In wherein said a plurality of annular element each comprises that two can optionally be opened with the increase and decrease paper or close with fixing paper and the semi-circular parts that allow it to move along described annular element.Described annular element is installed on two adjacent pivot axis that pass through and links together with on the articulated slab that moves pivotally in an elongated housing.The described articulated slab of support that described housing is loose is so that it can pivot with respect to described housing.When described articulated slab was in the position (180 °) of a coplane, the housing of described nothing distortion slightly was narrower than described articulated slab.Therefore when described articulated slab was switched to this position, it made described elastic shell distortion also produce an elastic force therein, and described elastic force makes described articulated slab pivot away from described co-planar locations in the mode that opens or closes described annular element.Therefore, when described annular element was closed, described elastic force hindered the motion of described articulated slab and described annular element is clamped together.Similarly, when described annular element was opened, described elastic force made it keep released state.The user needs can overcome this elastic force by manually opening or closing described annular element.In addition, in some mechanisms, the user can by move a bar being positioned at described mechanism one or both ends make described articulated slab by described co-planar locations to open or close described annular element (opening or closing described annular element) except manual.
A defective of this existing annular mechanism for loose-leaf binder is, when described annular element is closed, and the described annular element of elastic force quick-snap of described housing, a power might cause finger to be sandwiched between the described annular element simultaneously.What make that described annular element closes that required elastic force also will cause described articulated slab difficulty passes through described co-planar locations (180 °), therefore makes described annular element open and close the comparison difficulty.Another defective is that when described annular element was closed, it can not be locked together in together effectively.If therefore described mechanism gets loose, described annular element might be opened.Another defective is, through after a while, described housing might produce permanent distortion, and it reduces the ability that described annular element is fastened togather effectively, and might cause uneven moving or the gap between the annular element of described closure.
In order to overcome these defectives, some annular mechanism for loose-leaf binder comprise a control slide plate that directly links to each other in described bar.Described these control slide plates have convex inclination, that stretched out by the described opening on the described articulated slab, and when opening and closing described annular element, it can control the described pivoting action of described articulated slab rigidly.The patent No. is that 4566817,4571108 and 6276862 the United States Patent (USP) and the patent No. are that 2292343 BP shows such mechanism.In described these convexs some have a stop part, and when described annular element was closed, it can stop the pivoting action of described articulated slab and the annular element of described closure is fastened togather.The user is by handling described annular element or moving described bar, and described these mechanisms can be unlocked or close.But in order to make described mechanism sealed, the user must move described bar and described control slide plate and make it to be in the position that stops described articulated slab to pivot.
Described these mechanisms still have some defectives.When described annular element was closed, the elastic force of described housing can make that still described annular element is fastened togather.Described elastic force still has makes described annular element open and close the comparatively problem of difficulty.In addition, when described mechanism closed, it can not be sealed reliably.And the user must directly move described bar and described control slide plate so that described mechanism is sealed.In addition, the convex of control slide plate, especially its inclination in these mechanisms and stop part complex structure, manufacturing difficulty and consuming time.In addition, because the described articulated slab of the direct bias voltage of described control slide plate, so its relative broad and form to bear the power (promptly repeating to drive described articulated slab to pivot) that produces of reusing by a large-sized metal manufacturing.Therefore, be used to accept also relative wide of the opening of described these control slide plates on the described articulated slab, this just might weaken described articulated slab, so it must be formed by a large-sized metal manufacturing.This will cause manufacturing cost to increase.
Therefore, this just need be when the fixing described loose-leaf paper of described annular element, and described annular mechanism for loose-leaf binder can be sealed reliably, but the described annular element of described annular mechanism for loose-leaf binder can be opened easily and close and can not be fastened togather.The present invention promptly relates to described this annular mechanism for loose-leaf binder.

Referring to accompanying drawing of the present invention, Fig. 1 shows the circular ring loose-leaf binder mechanism according to the fixedly loose-leaf paper (not shown) of first embodiment of the invention.Described mechanism is by Reference numeral 1 expression, and is installed on one of the notebook ridge 3, and described notebook has a protecgulum 7 and a bonnet 9 hinged with described ridge 3.Described protecgulum 7 and bonnet 9 can move selectively so that the described paper that is fixed is capped or exposes.But other lip-deep circular ring loose-leaf binder mechanisms that are installed on except described notebook do not depart from the scope of the present invention equally.Described mechanism 1 generally includes 11, three annulus of a housing (each annulus is represented with Reference numeral 13) and a control structure (representing with Reference numeral 15).Described housing 11 supports described annulus 13 and described control structure 15, and described control structure 15 is used to close described mechanism 11 to be fixed in the paper (Fig. 2 A or 2B) on the described annulus 13 or to open and add paper (Fig. 3 A or 3B) on the described in the past annulus 13 of described mechanism.As will be described below, described control structure 15 can directly be closed and sealed described mechanism 1 or its can allow the elastic force of described housing 11 to open described mechanism 1.Referring to Fig. 4, described mechanism 1 comprises pair of hinge plates 17,19, and described articulated slab can pivot with the described annulus 13 of opening and closing with respect to described housing 11.Described control structure 15 comprises a drive rod 39, motion bar 21 and three locking elements 23,25,27, and described locking element and described articulated slab 17,19 interact to close and sealed described annulus 13 or make described annulus open.In addition, described mechanism 1 comprises an extension spring 29, and described spring is arranged in described housing 11, is used to make described motion bar 21 and described locking element 23,25,27 to move automatically to close and sealed described annulus 13.
Housing shown in Figure 4 11 elongated and have a symmetry, the roughly cross section of camber, and the center has the flat-top 31 of a rising.Described housing 11 is formed by the metal manufacturing, but also can be formed by other material manufacturings that is fit to, if the stable installation of the miscellaneous part of the described mechanism 1 of rigidity sufficient to guarantee of described material with and elasticity be enough to make it to play the effect of a spring.Described housing 11 has a longitudinal axis, two cutting shoulder and two longitudinal ends that laterally extend longitudinally relatively.Bottom frame 33 along the bending that two longitudinal cut limits of described housing 11 form comprises six slits 35 (having only 3 as seen at this), and described slit is arranged to accept described ring 13 (Fig. 2 A) along the length direction of described housing with three groups of laterally relative forms.Two protuberances 37 are protruded upward to connect described drive rod 39 by the end of described housing.Although another opposite end of described housing does not have a bar, should understand that the mechanism that its housing two ends respectively have a bar does not depart from the scope of the present invention.The flat-top 31 of described rising comprises two openings or eyelet 41,43, in order to accept and to connect the installation column 45,47 that described mechanism 1 can be fixed on the described notebook 5.Such as the various housings with asymmetric shape with and upper shed and the different housing of slit quantity do not depart from the scope of the present invention equally.
Described housing 11 loose grounds support described two articulated slabs 17,19 to enable at the generation pivoting action and and then to close described ring 13 (Fig. 2 A and 2B) or open described ring 13 (Fig. 3 A and 3B).Described each ring 13 comprises two annular elements 49, and described annular element 49 is installed on the adjacent articulated slab 17,19 and can moves between a closed position and an enable possition.It is circular that the cross section of described annular element 49 is generally, and formed by the material manufacturing that is suitable for such as steel.When described annular element 49 was in described closed position, it had formed " D " type annulus of a continuously basic and sealing or loop (Fig. 2 A and 2B) with fixing described loose-leaf paper and allow described these paper to move to another annular element along described ring 13 by an annular element 49.And when it was in the enable possition, described each annular element had formed a discontinuous open loop (Fig. 3 A and 3B) that is suitable for increasing and decreasing paper.Although in illustrated embodiment, described two annular elements 49 are all removable, and annular element is movable, the Immobile mechanism of another annular element does not depart from the scope of the present invention.In addition, the quantity of ring be not equal to 3 and the different mechanism of closed hoop do not depart from the scope of the present invention yet.
Referring to Fig. 4, described each articulated slab 17,19 is a thin strip, and it has inside and outside longitudinal cut limit and two longitudinal ends.The described inner longitudinal cut limit of described each articulated slab 17,19 has seven otch, and when described articulated slab 17,19 linked to each other, the corresponding otch of described each articulated slab alignd and formation opening as shown in Figure 5.First opening 51 is near having the shell end of described bar 39, and first of being used to receive by described articulated slab 17,19 installs column 45.The second and the 3rd opening 53,55 is respectively applied for accepts first and second locking element 23,25, and this point will be illustrated below.The 4th opening 61 comprises two recesses 63 that lay respectively on the articulated slab 17,19.Described two recesses 63 can be accepted one of described extension spring 29 second end 65.One the 5th opening 67 is used to hold the part of the main body 69 of described extension spring 29.One the 6th opening 71 is accepted one the 3rd locking element 27 in the mode identical with described second and third opening 53,55.One minion mouth 75 is near the shell end that does not have described bar 39 and in order to receive one second installation column 47 by described articulated slab 17,19.
Described interconnective articulated slab 17,19 has formed a center hinge with pivotal axis one another along its parallel connection in longitudinal cut limit, inside of adjoining mutually.Described housing 11 receives the plate 17,19 that links to each other, thereby makes the outside longitudinal cut limit pine loose ground of described each plate be positioned on the corresponding curved bottom frame 33 of described housing.Therefore, described articulated slab 17,19 is fixed on the described housing 11, but described cutting shoulder can move in described frame 33, thereby makes described plate 17,19 to pivot arbitrarily around described pivotal axis.When described articulated slab 17,19 pivots and when opening described ring 13, move on the described pivotal axis (promptly shown in Fig. 3 B towards as described in the flat-top 31 of rising of housing move), and pivot when closing described ring 13 when described plate 17,19, described pivotal axis moves down the flat-top 31 of the rising of described housing (promptly away from).In addition, described articulated slab 17,19 is designed to pivot in described housing 11, therefore the included angle A between surface outside the described plate face of described housing (promptly away from) is always less than 180 °, and described pivotal axis moves to or be lower than a co-planar locations (being that included angle A is 180 ° position) of described plate 17,19 never.Therefore, the described articulated slab of elastic force bias voltage of described housing and the pivot that causes described articulated slab be only in order to opening described annular element 49, and can not cause closing of described annular element 49.But should understand that in certain embodiments, the angle between the described outer surface can be greater than 180 °, so, the elastic force of housing can be towards the described articulated slab of a closed position bias voltage.In addition, the present invention's certain embodiments can be designed to described articulated slab to pass one of described articulated slab co-planar locations (180 °).
As noted earlier, described housing 11 support and control structures 15 move with respect to described housing 11 making it, thereby control the pivot of described articulated slab 17,19 and the locking annular element 49 of closing reliably.Shown in Fig. 4 and 5, the described drive rod 39 of described controlling organization is formed by the rigid material or the composite manufacturing that are suitable for such as metal or plastics or the like.It comprises that a head 79 that enlarges is so that firmly grasp described bar 39 and apply power to it.First swivel pin 81 of the protuberance 37 of a upper opening 83 that passes described bar 39 and described housing is installed on described bar 39 on the described housing 11 and makes it and pivots with respect to described housing 11.One is passed the lower openings 87 of described bar 39 and second swivel pin 81 of the opening 89 on the described intermediate connector 91 makes described bar 39 link to each other with described connector 91.Described intermediate connector 91 links to each other described bar 39 with described motion bar 21, convert the linear movement of described motion bar to the pivoting action with described bar.Although the motion of described motion bar not exclusively is linear also, sees from angle of the present invention and can think that it is linear movement.
Referring to Fig. 4, described intermediate connector 91 is generally has a flat web and the slender beam of two side flanges.It has a width first end slightly wide than one second end.More particularly, the second narrower end of described intermediate connector 91 has a protuberance 93, and described protuberance has an end 95 that enlarges, and described end is arranged in a slit 99 of one of described motion bar 21 first end.Described motion bar end is bent downwardly simultaneously and forms a shoulder 101, and described shoulder 101 can prevent that a side of described intermediate connector 91 is pushed to described motion bar 21.The end 95 of the described expansion of described protuberance 93 can combine with the opposite side of described shoulder 101, thereby pushes described motion bar 21 to described bar 39.The slit 99 that is used to admit described protuberance 93 is slim-lined construction along the length direction of described motion bar 21.Therefore, described intermediate connector 91 can pivot up and down arbitrarily with respect to described motion bar 21.So described intermediate connector 91 can transfer to described motion bar 21 by described pivot rods 39 with a linear movement.In addition, described motion bar 21 can move up and down and can not interfere described intermediate connector 91.Illustrated connector 91 also comprises an elongated opening 103, and described opening is used to receive the described first installation column 45 that passes described connector 91 and can allows described connector 91 to move with respect to described installation column 45.
Shown in Fig. 4-6, described motion bar 21 can receive the pivoting action of described bar with vertically moving along described housing.Described motion bar 21 is a straight elongated layer, is formed by a kind of metal or other material manufacturings with enough rigidity.Its longitudinal axis that is parallel to described housing is usually placed, and is positioned at the below of flat-top 31 of described rising and the top of described articulated slab 17,19.A protruding seat 105 is along the longitudinal axis placement of described motion bar and towards one second end.Described protruding seat 105 is integral with described motion bar 21 and is extended downwards by the surface of described motion bar, thereby has formed a uncinus in order to connect one of described extension spring first end 107.Should understand, difform motion bar, the motion bar that perhaps has the protruding seat of the independence that is attached thereto does not depart from the scope of the present invention equally.
Described motion bar 21 also comprises three locking elements 23,25,27, described locking element can (1) makes described articulated slab 17,19 pivot with the pivoting action of closing described annular element 49 and stoping described articulated slab with the sealed described annular element of closing 49, perhaps (2) make described articulated slab 17,19 pivot to open described annular element 49 (that is, it can align with corresponding articulated slab opening 53,55,71 and make described articulated slab 17,19 pivot and open described annular element 49 with the elastic force that allows described housing).Described each locking element 23,25,27 of illustrated embodiment comprises alternate flange 109, and described flange and described motion bar 21 are integral part and bend 90 ° (Fig. 6) downwards by one of described motion bar longitudinal cut limit.Accordingly, the flat face of described each flange is parallel with the flat face of other flanges and concordant with the longitudinal axis of described motion bar.In addition, the edge has formed a convex 113 that can combine and make its pivot with described articulated slab 17,19 at angle under described each flange.Should understand that described locking element can be single, or more than two parts, and the number of the locking element of described control structure can be not equal to three or described locking element can adopt difformity, above-mentionedly all do not depart from the scope of the present invention.
Described extension spring 29 is biased into a latched position that stops the pivoting action of described articulated slab with described motion bar 21 and described three locking elements 23,25,27.When described locking element 23,25,27 moved and do not align with the corresponding opening 53,55,71 of described articulated slab 17,19, described extension spring 29 pulled to described lock position with described motion bar 21 and locking element 23,25,27 automatically.Described extension spring 29 is usually located between described motion bar 21 and the described articulated slab 17,19, and part is arranged in the 5th opening 67 of described articulated slab.Because the axis of extension spring need not consistent with the moving direction of a motion bar so that described motion bar and described locking element move to a lock position, so wish that described extension spring has so bias effect, because it can provide multiple position to select.
Referring to Fig. 5,7 and 8, described control structure 15 can optionally make described mechanism 1 one close and a latched position and an enable possition between move (Fig. 8).Close and latched position described, described annular element 49 combines and can not be pulled away from.The orientation of described articulated slab 17,19 makes the included angle A between its outer surface reach maximum, but still vertical with the motion bar 21 of close housing one end that comprises bar 39 less than 180 ° (Fig. 2 B) and described drive rod 39.Therefore, in fact described first, second and the 3rd locking element 23,25,27 and do not align with corresponding articulated slab opening 53,55,71 between described articulated slab 17,19 and described housing 11.In this position, because the size of described locking element 23,25,27 makes the space between the flat-top 31 of its rising that occupies described articulated slab 17,19 and described housing along described motion bar 21 fully, so it can stop any power of making that described annular element 49 is opened of being intended to.Therefore when described articulated slab 17,19 upwards promotes described locking element 23,25,27 (when described articulated slab 17,19 pivots when opening described ring-type element 49), it combine with described locking element 23,25,27 immediately and also is intended to make described locking element 23,25,27 and 21 risings of described motion bar.Thereby, described locking element 23,25,27 and described housing 11 overcomes described opening movement and make described ring-type element 49 keep together.
In order to open described mechanism 1, the outwards also downward described bar 30 (Fig. 7) that pivots of user.This just makes described intermediate connector 91 and motion bar 21 away from an end of the described housing with bar 39, and makes described motion bar 21 and described locking element 23,25,27 away from described lock position.When described motion bar 21 and described locking element 23,25,27 moved, described extension spring 29 stretched and produces one and increases gradually to make it to get back to the restoring force of described lock position.But along with user's described bar 39 that continues to pivot, described motion bar 21 and and described locking element 23,25,27 continue to move until described three locking elements 23,25,27 and align with corresponding second, third and the 6th opening 53,55,71 on the described articulated slab 17,19 simultaneously.In described this middle transition position, described locking element 23,25,27 no longer stops the pivoting action of described articulated slab, and the elastic force of described housing automatically makes described articulated slab 17,19 pivot simultaneously.Three corresponding openings 53,55,71 of described articulated slab are crossed described locking element 23,25,27, and simultaneously described annular element 49 is opened (Fig. 8).At this, the included angle A between the described outer surface of described articulated slab reaches minimum (Fig. 3 B), simultaneously the EDGE CONTACT of the respective openings 53,55,71 of a vertical component effect 115 (referring to Fig. 6) of the convex of described each locking element and described articulated slab.This has just stoped described locking element 23,25,27 and can prevent to cause described motion bar 21 to move and the contraction that is back to the described extension spring 29 of described lock position.In addition, the elastic force of described housing makes the unlatching of described annular element 49 be able to, so the user can unclamp described bar 39 and increase and decrease paper to described mechanism 1.
In order to make described mechanism 1 be back to described closing and latched position, the inside and described bar 39 that upwards pivots of user pulls back described intermediate connector 91 and described motion bar 21 to the shell ends with described bar 39 mutually on the contrary with described unlatching effect.This just makes the edge junction of the respective openings on convex and the described articulated slab 17,19 of described locking element merge and overcomes the power opposite with the unlatching effect of described articulated slab (being the convex 113 of described locking element and the frictional force between the described articulated slab 17,19 and the elastic force of described housing 11).Therefore, described articulated slab 17,19 makes described each convex 113 slowly glide and little by little drives described annular element 49 and moves together.Described annular element 49 once close fully and the described outer surface of described articulated slab between included angle A when reaching maximum once more (Fig. 2 B), described convex 113 breaks away from bonding state with the edge of described opening, simultaneously described extension spring 29 shrinks, thereby automatically described motion bar 21 and described locking element 23,25,27 is returned to described lock position.Described locking element 23,25,27 returns the position of the pivoting action of its described plate of prevention that is positioned at described articulated slab 17,19 rears fully.By promoting described annular element 49, described mechanism 1 also can be back to it and close and latched position.This just makes described articulated slab 17,19 pivot and therefore makes described opening 53,55,71 move to the position below described locking element 23,25,27, thereby allows described extension spring 29 contractions and described motion bar 21 and described locking element 23,25,27 are returned to described lock position.
The present invention's circular ring loose-leaf binder mechanism can be fixed described loose-leaf paper effectively when described annular element 49 is closed, and can prevent effectively that the described annular element of closing 49 from opening unexpectedly.This is because when described ring-type element 49 closures, described extension spring 29 automatically makes described motion bar 21 and described locking element 23,25,27 be positioned at described lock position, thereby has eliminated the described bar of manual operation with the described mechanism 1 of locking.This locking characteristic and described mechanism 1 are how to close irrelevant (promptly whether directly pushed away together with described annular element 49 or whether described bar pivots irrelevant).Among this external described embodiment, when described annular element 49 is closed, because the convex of described locking element is the described articulated slab 17,19 of wedging and little by little make described annular element 49 closures controllably, so described annular element 49 can suddenly not block and be in the same place.Simultaneously, owing to described three locking elements 23,25,27 are provided with at interval along the length direction of described articulated slab 17,19 equably, so when described mechanism 1 closure, it is dispensed to power on the described annular element 49 equably.In addition, described motion bar 21 and described locking element 23,25,27 fully occupies the zone between the flat-top 31 of described articulated slab 17,19 and described rising usually, fully stoped the motion that causes the described articulated slab that described annular element 49 opens.Therefore, described annular element is locked at together reliably, and the gap between the described annular element 49 can minimize under situation about not eliminating.Since at described locking element 23,25,27 with before corresponding opening 53,55,71 on the described articulated slab 17,19 aligns, the user only needs can allow the elastic force of housing automatically to make described articulated slab 17,19 pivot to open described annular element 49, so the unlatching of described mechanism 1 is more easy than prior art the short distance of described extension spring 29 stretchings one.Similarly, because the mechanical property that had of described bar 39, therefore the pivoting action of described bar has reduced the size that makes described motion bar 21 and locking element 23,25,27 move and open the required power of (or closing) described annular element 49.Before finally opening or close described annular element, must overcome other internal friction power such as the bar that directly promotes or spur a motion bar that links to each other with existing mechanism.
Fig. 9 shows another form of motion bar, and it is represented with Reference numeral 119.Described motion bar 119 comprises three juts that are integrally formed therewith 121 (only showing in the accompanying drawing).Described each jut 121 is by 90 ° of the downward bendings in the surface of described bar and be used to receive and secure a locking element 123 that is independent of described bar 119 and forms.Described locking element 123 is generally block and can and can the described articulated slab 17,19 of wedging forms with plastics or other material manufacturings that is fit to of together moving with described annular element 49 by the pivoting action that can stop described articulated slab.The described locking element 123 of convex of locking element flange 109 that is similar to the described motion bar of described first embodiment has an angled convex 125.Therefore, each embodiment described herein can comprise this motion bar 119.
Figure 10 A-the 12nd is shown in Fig. 1-8 and second embodiment of one of described the present invention annular loose-leaf binder mechanism.Described mechanism is with Reference numeral 201 expressions, and parts corresponding to those in the first embodiment adopt identical Reference numeral in the described mechanism simultaneously, just add " 200 ".Described embodiment and described first embodiment are similar, but comprise two line structure springs 327 that link to each other with articulated slab 17,19 bottom sides that interconnect.When described locking element 223,225,227 alignd with corresponding opening 253,255,271 on the described articulated slab 217,219, described spring 327 promoted described plate 217,219 and pivots so that described annular element 249 is opened.In addition, in the present embodiment, when making that when described articulated slab 217,219 pivots described annular element 249 is closed, the pivot axis of described articulated slab moves in the below of a coplane position (180 °).Accordingly, in described position, the described angle A that is formed by the described outer surface of described articulated slab 217,219 is greater than 180 ° (Figure 10 B).
In order to receive described line structure spring 327, along described each articulated slab 217,219 vertically outside cutting shoulder have two recesses 329 and otch 331 (having only recess 329 on the described articulated slab 219 and otch 331 as seen).A jut is arranged, formed betwixt to described recess 329 in mode arranged side by side, and be positioned at one of described articulated slab end; Described otch 331 is positioned at the other end of described articulated slab.On described two articulated slabs 217,219, described jut and described otch 331 are placed with opposite order, thereby when described two articulated slabs 217,219 linked to each other, the jut of a described plate passed the otch 331 of described another plate.
Shown in Figure 10 A, 11A and 12, described line structure spring 327 is generally a circular metal line, and roughly forms the elongated octagon (described openend forms one of described octagon side) with an openend and a blind end.Described blind end upwards bends 90 °, cooperates with described jut and matches with two recesses 329 of one of described articulated slab that interconnects 217,219.The free end of described jut is positioned at the rear at one of described housing edge 233, so that the blind end of described spring 327 can be supported on the described jut.The openend of described spring 327 comprises two ends 335, and described end bends respectively twice and forms hook-type.Wherein bending for the first time is for upwards bending 90 °, and bending for the second time is 90 ° of outwards bendings.Described terminal 335 are assemblied in the otch 331 of one second the articulated slab 217,219 that links to each other separably, thus make the main body of described line spring be positioned at substantially the described articulated slab that is connected 217,219 below.At described link position, when described articulated slab 217,219 orientation of living in made that described annular element 49 is opened, described line spring 327 was in relaxed state.That the main body of described line spring 327 upwards slightly is is arc (promptly towards the articulated slab 217,219 (Figure 11 B) that interconnects), thereby makes angle A that the outer surface of the described articulated slab that interconnects 217,219 forms less than 180 ° (being the top that the pivot axis of described articulated slab is positioned at described articulated slab 217,219 co-planar locations (180 °)).When described locking element 223,225,227 make described articulated slab 217,219 move down and by described co-planar locations (180 °) when closing described ring-type element 249, the line spring 327 of described each archwise flattens and pressurized (Figure 10 B).When described locking element 223,225,227 moves and when aliging with corresponding opening 253,255,271 on the described articulated slab 217,219 backward, line spring 327 automatisms of described pressurized are on described articulated slab 217,219 and make it upwards to pivot and by described co-planar locations (180 °), and then make described annular element 249 unlatchings.Owing to the described articulated slab 217,219 of described line spring 327 bias voltages makes described annular element 249 open, therefore the elastic force of the described housing of present embodiment can be slightly less than the housing elastic force of the mechanism of prior art, this just makes that closing of described mechanism 201 is more easy.Should understand that although described in the present embodiment mechanism 201 comprises two line springs 327, the number of line spring is not equal to two and does not depart from the scope of the present invention equally.
Figure 13-15 shows the present invention's the 3rd embodiment, and with the described mechanism of Reference numeral 401 expressions.Described embodiment part corresponding to those in the first embodiment adopts identical Reference numeral, has just added prefix " 400 ".This embodiment and described first embodiment are similar.Shown in Figure 13 and 14, it comprises a drive rod 439 that is similar to described first embodiment, but its directly pivot-hinge fishplate bar 417,419 with the described annular element 449 of opening and closing.In described mechanism 401, described bar 439 comprises a closure arm 549 and an opening arm 551, and described two arms combine with described articulated slab 417,419 to make it pivot and to make described annular element 449 move.Described two arms 549,551 are perpendicular to described bar 439 extension parallel to each other.It is that a groove that is used to receive one of described each articulated slab fingers 555 (Figure 13) separates.Described each fingers 555 is extended and is narrower than slightly the remainder of described articulated slab by an end of described articulated slab.When described articulated slab 417,419 present positions pivoted it in described housing 411, described fingers 555 stretched out and is arranged in the groove of described bar by described housing 411, thereby allowed described bar 439 to drive described articulated slabs and make it to move pivotally.
Described mechanism 401 comprises that also another is the intermediate connector of wire connections structure 541.Described wire connections 541 is a thin metal wire with both ends, and described both ends bend 90 ° so that described drive rod 439 is linked to each other with a motion bar 421 along identical direction.One end of described wiring connector is arranged in an aperture 547 of the described closure arm 549 of described bar.The other end of described connector is arranged in a slit 539 on one of two side flanges of described motion bar, and wherein said side flange 537 is formed by a part 90 ° of the bendings downwards on two longitudinal cut limits of described motion bar.Therefore, the use of described two wiring connectors is feasible.But should understand that when adopting a wiring connector, the described slit that described connector is arranged in any side flange does not depart from the scope of the present invention equally.
Embodiment is described as the front, and the described drive rod 439 of described mechanism 401 links to each other with one of described housing 411 end pivot.Described housing 411 comprise two that stretch out downwards by the one shell end, in order to hold a lug boss 527 (Figure 13) that connects the swivel pin 529 of described bar 439.In addition, the flat top portion 431 that raises of one of described housing 411 comprises that two openings 531 are in order to hold and to be connected with groove rivet 533.Specifically referring to Figure 15 A, described rivet 533 (only illustrating one among the figure) is slidingly connected described motion bar 421 by lip-deep two slits 435 of described motion bar with described housing 411, allow described motion bar 421 to relatively move with respect to the length direction of described rivet along described housing 411.This just makes to pivot at described articulated slab 417,419 and lives when closing described annular element 449 to open, described motion bar 421 and vertically the moving of described locking element 423,425,427 that links to each other minimize (promptly when described mechanism 401 was in an enable possition, it can stop described locking element 423,425,427 to combine (not shown) with the ridge 403 of described notebook effectively).In addition in the present embodiment, the arrangement of the opening on the described articulated slab and described first and second embodiment are different slightly, and the be arranged so that described motion bar 421 and the described locking element 423,425,427 of extension spring 429 is biased to away from the shell end with described bar 439 in the present embodiment.Wherein one first opening 557 is close to have the shell end of described bar 439 and be used for reception and passes one of described articulated slab 417,419 first installation column 445.One second opening 559 is used to place one first locking element 423.One the 3rd opening 561 holds the main body 469 of described extension spring.One the 4th opening 563 has the notch 463 (Figure 13) in order to second end 465 that receives described extension spring.The one the 5th and the 6th opening 565,567 is used to place the described second and the 3rd locking element 425,427, one minion mouths 569 near not having the shell end of described bar 439, passes one of described articulated slab 417,419 second in order to reception column 447 is installed.
In the present embodiment, closing and latched position (Figure 15 A), the pivot axis of described articulated slab 417,419 is positioned at below, a coplane position (180 °), and described locking element 423,425,427 is relatively away from the shell end with described bar 439 (comparing with the corresponding position of described first and second embodiment) simultaneously.When described bar 439 pivots so that described mechanism 401 is when opening, described bar 439 pushes have described wiring connector 541, motion bar 421 and described locking element 423,425,427 shell end of described bar 439 to.But when described locking element 423,425,427 when corresponding the second, the 5th and the 6th opening 559,563,567 on the described articulated slab 417,419 aligns, described articulated slab 417,419 can automatically not pivot.The elastic force of described housing stops its pivot.In contrast, the opening arm 551 of described bar combines with the bottom of the described finger piece of described articulated slab, forces described articulated slab 417,419 upwards to pivot and by described co-planar locations (180 °).Described opening 559,563,567 on the described articulated slab moves through corresponding locking element 423,425,427, and described annular element 449 is opened simultaneously.When described mechanism 401 was closed, the closure arm 549 of described bar combined with the top side of the described finger piece of described articulated slab, made described articulated slab 417,419 pivots and by described co-planar locations (180 °) downwards at leisure.Described extension spring 429 shrinks and pushes have described motion bar 421 and described locking element 423,425,427 the described shell end (promptly pushing described lock position to) of described bar 439 to.In the present embodiment, described closure arm 549 makes described articulated slab 417,419 pivots only make described articulated slab 417,419 pivot to close described annular element 449 to close described annular element 44 described closure arm 549 alone.Described locking element can not resemble and promote described articulated slab 417,419 pivots among described first and second embodiment the corresponding parts.
Figure 16 and Figure 17 B show the present invention's the 4th embodiment.The described mechanism of present embodiment is usually by Reference numeral 601 expressions.Wherein adopt identical Reference numeral, just prefix " 600 " in addition with the corresponding parts of described first embodiment.But and adopt identical Reference numeral with the corresponding parts that are not included among described first embodiment of described the 3rd embodiment, prefix " 400 " in addition just.Present embodiment and described the 3rd embodiment are similar.But in the present embodiment, first end 707 of an extension spring links to each other with a motion bar 621, and a bayonet lock 735 on the flat top portion 631 of its second end 665 and the rising that is positioned at a housing links to each other.
In the present embodiment, described motion bar 621 is a rigidity groove, has a straight web and two side flanges.It comprises three locking elements, and wherein said each locking element comprises two whole locking flanges 749 that are connected of the described side flange with described motion bar.Describedly longitudinally stretch out downwards by described side flange, thereby make described three locking flanges 749 be positioned at each side of described motion bar with the locking flange 749 of identical distance setting.Wherein one first pair of locking flange is near having the described shell end of described drive rod 639 and having a slit 751 in order to receive an end of a wiring connector 941, and described wiring connector is used to connect described motion bar 621 and described drive rod 639.Also have two additional openings 731,733 on the web of described motion bar 621, described opening is in order to admit the corresponding connecting portion of described extension spring and described motion bar 621 and described housing 611.One of them first additional opening 731 locates and is used to place described first end 707 of described extension spring near the longitudinal center of described motion bar.One second additional opening 733 is used to receive the part of an extension spring main body 669 between the described first additional opening 731 and a motion bar slit 934.Because described extension spring 629 does not link to each other with described articulated slab 617,619, therefore described articulated slab 617,619 includes only four openings (Figure 17 A).Wherein one first opening 651 is near the described shell end with described bar 639 and pass one of described articulated slab 617,619 first in order to reception and column 645, second, third and the 4th opening 653,655,671 are installed are respectively applied for and receive corresponding locking element 747.
In addition, in the present embodiment, described drive rod 639 is identical with the described drive rod of described the 3rd embodiment, but is installed on one independently on the rod installation part 741.Described rod installation part 741 comprises two protuberances that stretch out 743 downwards, and described protuberance receives one and is used for described bar 639 is mounted to swivel pin 745 on the described housing 611.Described rod installation part 741 links to each other with described housing 611 by a rivet that passes the rising flat top portion 631 of described housing.Other aspects of described mechanism 601 are identical with the corresponding part of described the 3rd embodiment.
Figure 18-22 shows the 5th embodiment (by Reference numeral 1001 expressions) of the present invention's annular loose-leaf binder mechanism.Specifically, described mechanism is in fact identical with the described mechanism 601 of the 4th embodiment shown in Figure 16-17B, but has done following improvement.Wherein adopt identical Reference numeral, just prefix " 400 " in addition with the described mechanism of described the 4th embodiment corresponding parts.Referring to Figure 18 and Figure 19, described mechanism 1001 comprises the described bar 639 similar drive rods 1039 in the described mechanism 601 with the 4th embodiment.It is installed on one of the vertical end that is positioned at a housing independently on the rod installation part 1141, and comprise a closure arm 1349 and an opening arm 1351, described two arms in order to the described fingers 1355 of described articulated slab in conjunction with to open and close described annular element 1049.But in described mechanism 1001, described bar 1039 is a T-shape, has the elongated and head 1079 that enlarges, and the length direction of described head is roughly parallel to the longitudinal axis of described housing.Described head 1079 and described bar 1039 are in aggregates, and its end slightly upwards is arc so that clamp described bar 1039 and apply power to it simultaneously.Yet should understand that housing 1011 (referring to Figure 22) did not depart from the scope of the present invention equally as described in described drive rod 1039 directly was installed on shown in mechanism 401 as described in the 3rd embodiment of Figure 13-15.
As described drive rod 1039, the described motion bar 621 of the described mechanism of one of present embodiment motion bar 1021 and the 4th embodiment is similar.But shown in Figure 18-21, in this mechanism 1001, described motion bar 1021 comprises that three roughly are block locking element 1147, and described locking element stretches out downwards with the whole connection of one of described motion bar web and with identical longitudinal separation.But should understand that the described locking element of described mechanism links to each other with described motion bar independently and do not break away from the present invention's claimed scope equally.Described locking element 1147 comprises flat relatively side and a bottom surface, and described bottom surface tilts to a narrower central area.The locking element of described other structures does not break away from the present invention's claimed scope equally.One first locking element 747 is near described housing one end with bar 1039, and have a slit 1151 in order to receiving an one of wiring connector 1341 hook end, and described motion bar 1021 is linked to each other with described drive rod 1039 in the mode identical with the described wiring connector 941 of the described mechanism of described the 4th embodiment.
Shown in Figure 18,20 and 21, the described articulated slab 1017,1019 of the described mechanism described articulated slab with the described mechanism of described the 4th embodiment basically is identical, but has a curved lug boss 1163 on each otch.In fact described lug boss 1163 can prevent along the distortion of the burr of the edge of described otch (when making described otch on described articulated slab 1017,1019, described burr usually are formed at the edge of described otch).When described articulated slab 1017,1019 interconnects, the described lug boss of described respective cut 1163 next-door neighbours and be positioned at described second and third and four openings, 1053,1055,1071 places of described articulated slab.Specifically, described boss is in the edge of described each opening, corresponding block locking element 1147 and the position of described register and the position that do not line up between when mobile by described lug boss.Therefore, described lug boss 1163 help moving of described block locking element 1147 so that and described second, third and 1053,1055,1071 alignment of the 4th opening of described articulated slab and do not line up, prevent the inordinate wear of described locking element 1147 when repeating to slip over corresponding edge of opening place simultaneously.Should understand that described these lug bosses 1163 can be used for the articulated slab of said each mechanism, be not restricted to the articulated slab 1017,1019 of the described mechanism of present embodiment simultaneously.
