Abstract
A ring binder mechanism includes a housing that supports two hinge plat es for loose pivoting motion, moving the ring members apart or together. The mechanism also includes an actuating lever pivotally mounted on the housing. The lever moves a travel bar and its locking elements for controllably pivoting the hinge plates and the ring members mounted thereon between closed and open position s. In particular, the locking elements cam the hinge plates to softly close the ring members. When the ring members are apart, the locking elements register with openings in at least one of the hinge plates. When the ring members are together, the locking elements are substantially out of registration with the openings , blocking the hinge plates from pivoting to separate the ring members. The travel bar is formed with reinforcing structure to resist deforming the travel bar upon repeated operation.
Description
Technical field
The present invention relates to be used to keep the circular clip mechanism of loose leaf paper, relate in particular to the improvement mechanism that jerks and the ring component of closure is locked together securely that when ring component is closed, alleviates ring component.
Background technology
As known in the art, typical circular clip mechanism will remain in file or the notebook such as the loose leaf paper of perforated paper.It is characterized in that comprising a plurality of rings, each ring comprises two semi-ring parts, and the semi-ring parts can be opened selectively to increase or taking-up page or closed selectively to keep page and page is moved along ring.Ring component is installed on two adjacent articulated slabs, and articulated slab combines around pivot axis, so that move pivotally in thin-long casing.Housing keeps articulated slab loosely, so that articulated slab can pivot with respect to housing.When articulated slab when co-planar locations (180 °), deformation-free housing is narrower slightly than the articulated slab of combination.When articulated slab pivoted by this position, they made the elastic shell distortion and produce elastic force in housings, impelled articulated slab to pivot and left co-planar locations to open or the closed hoop parts.Like this, when ring component was closed, elastic force hindered articulated slab and moves and ring component is clipped together.Similarly, when ring component was opened, elastic force made them keep separating.The operator can overcome elastic force by manually drawing back ring component or they being pushed away together.In addition, in some mechanism, the operator can move the control handle that is positioned at these mechanism one or both ends, makes articulated slab move through co-planar locations, to open or closed hoop parts (except manually drawing back ring component or they being pushed away together).
A shortcoming of these typical circular clip mechanisms is that when ring component was closed, the elastic force of housing was interlocked them fast, and generation may make the power that is sandwiched between the ring component of pointing.The required big elastic force of retaining ring members close also makes articulated slab pivot and becomes difficult by co-planar locations, thereby is difficult to open or the closed hoop parts.Another shortcoming is that when ring component was closed, they can not lock together reliably.If this mechanism unexpectedly drops, ring component may by mistake be opened.Also have a shortcoming to be, as time passes, housing may begin permanent deformation, has reduced its ability that ring component is clipped together equably, and may cause causing between the ring component of closure inhomogeneous moving or the gap.
In order to address these problems, some circular clip mechanisms comprise the control slide block that is directly installed on the control handle.The control slide block has the cam face of inclination, and cam face passes the opening on the articulated slab, so that control the pivoting action of articulated slab rigidly when the open and close ring component.Such mechanism example is presented in United States Patent(USP) Nos. 4566817,4571108 and 6276862, and among the BP No.2292343.Some cam faces comprise retainer, are used for stoping when ring component is closed the pivoting action of articulated slab, and the ring component of closure is locked together.
But these mechanisms still have shortcoming, and when ring component was closed, the elastic force of housing can they be interlocked.Elastic force also makes the open and close ring component become difficult.And, the control slide block in these mechanisms, especially cam face of Qing Xieing and retainer are complex-shaped, and are difficult to manufacturing and very time-consuming.In addition, because control slide block direct bias voltage articulated slab, their are broad relatively usually, and may be made by big specification metal, to stand and to use (that is, bias voltage articulated slab to pivot) repeatedly relevant power repeatedly.Therefore, receive the also relative broad of possibility of these openings of controlling slide blocks on the articulated slab, thereby weakened the intensity of articulated slab, make them also must make by big specification metal.The cost costliness of using big specification metal to make that batch is made.In addition, the engagement repeatedly of controlling slide block and articulated slab in operation may make the malformation of control slide block, makes slide block that articulated slab is fully pivoted to open or the closed hoop parts.The slide block of distortion is closed hoop parts or the ring component of closure locked together fully, produce the gap between the ring component of closure.These problems all make circular clip mechanism not easy to operate.
Other circular clip mechanism is being attempted solving and is being avoided ring component to jerk and reliably ring component is locked in the problem of closing position.For example, some arrangement of mechanism articulated slabs make them never pass through co-planar locations when pivot is mobile.Avoid the result of articulated slab by co-planar locations, ring component can not effectively be interlocked when closure.But, be applied on the ring component closing force relatively a little less than, need provide independent locking device with the retaining ring members close.The example of such circular clip mechanism is presented in the U.S. Patent No. 5660490.Another program is to arrange articulated slab and housing, makes articulated slab only more weakly by the housing bias voltage.This can be by realizing like this, increases independent metal filate spring in the bottom side of articulated slab so that bias voltage to be provided, thereby make articulated slab be pivoted to the position that ring component is opened.The topology example of this circular clip mechanism is presented among people's such as Koike the U.S. Patent application No.2003/0123923.In the mechanism of these types, the end of ring component is formed with hook, meshes when being hooked in the closed hoop parts, is in the close position with the retaining ring parts.It needs some skills to operate ring component to mesh or to separate them.If ring component is equipped with loose leaf paper, it is difficult more that operation becomes.And hook more is subject to be not intended to open the influence of the power of marmon clamp.In addition, the feasible clumsiness and difficult more of operating of circular clip mechanism that has a plurality of ring components that need mesh or open hook simultaneously.
As a result, need a kind of like this circular clip mechanism, it can be locked securely keeping loose leaf paper, and its ring component open and close reliably when assembling page, and can not be interlocked suddenly when ring component is closed.The present invention is directed to this circular clip mechanism.
Summary of the invention
The present invention relates to be used to keep the circular clip mechanism of loose leaf paper.This mechanism comprises: the housing with longitudinal end; With articulated slab, has at least one opening by housings support on the articulated slab with respect to described housing pivoting action.Loose leaf paper is held in a plurality of environmental protection.Each ring comprise be installed on first articulated slab, and first ring component that can move with respect to second articulated slab along with the pivoting action of first articulated slab.In closing position, two ring components form continuous substantially closed hoop, move to another ring component along ring from a ring component with the loose leaf paper that allows to be held by environmental protection.At open position, two ring components form the discontinuous ring of opening, to increase or to take out loose leaf paper from ring.This structure also comprises the carriage release lever that can move with respect to housing and articulated slab translation, and carriage release lever has two longitudinal edges; With the locking element that can move with carriage release lever.When locking element from described articulated slab on the position of described register when moving to the position that does not line up substantially with described opening, locking element and the engagement of at least one articulated slab also produce the pivoting action of articulated slab.Carriage release lever comprises the reinforcement structure, strengthens structure fabrication and is arranged to stop around the axis bending of carriage release lever longitudinal extension and stops axis bending around the carriage release lever width, to strengthen carriage release lever.
Aspect other, a kind of method that forms the reinforcement carriage release lever of circular clip mechanism is included in the step that forms at least one indent on the material piece substantially.Subsequently along axis cutting material sheet, so that indent is divided into two part indents.Material piece is bent at part indent place to form strengthens structure, overcomes axial bending to strengthen carriage release lever.
Further feature of the present invention partly is significantly, partly points out following.

With reference to Fig. 4, housing 11 is elongated, and have a symmetry, the cross section of camber substantially, the center has a rising flat top portion 23.Housing 11 is made of metal, but also can be made by other material that is fit to, the stable installation of other parts of the rigidity sufficient to guarantee mechanism 1 of described material with and elasticity be enough to make it to play the effect of a spring.Housing 11 has a longitudinal axis, two edge and two longitudinal end 11a that laterally extend longitudinally relatively, 11b.Each longitudinal edge formation that bends base 25 along housing, two bending bases 25 have six slits 27 (having only 3 as seen at this), and slit is arranged to accept ring 13 (with reference to Fig. 2 A and 3A) along the length direction of housing 11 with three pairs of horizontal relative forms.In an end of housing, two protuberances 29 protrude upward, and are used to install the actuation control handle 31 of control structure.Another opposite end of housing does not have control handle, but should be understood that, has the mechanism that two actuation control handles or actuation control handle be installed between the end and does not depart from the scope of the present invention equally.The rising flat top portion 23 of housing has two openings 33,35, and opening is used to receive and install the erection column 37,39 that mechanism 1 can be fixed on the notebook 5.Should be understood that difform housing comprises the housing of asymmetric shape and has the opening of varying number or the housing of slit does not depart from the scope of the present invention.
With reference to Figure 4 and 5, each articulated slab 19,21 is a thin strip, and it has inside and outside longitudinal edge and two longitudinal ends.Each articulated slab 19, longitudinal edge has five otch in 21 along its, when articulated slab 19,21 interconnects, and the respective cut alignment on each articulated slab and form five openings.First opening 43 is near having the shell end of control handle 31, and is used to receive first erection column 37 by articulated slab 19,21.Second, third and the 4th opening 45,47,49 are respectively applied for accepts first, second and the 3rd locking element 51,53,55, and this point will be illustrated below.The 5th opening 57 is used to receive second erection column 39 by articulated slab 19,21 near not having the shell end of control handle 31.Each articulated slab 19,21 also comprises two notches 59 and the otch 61 along the outer longitudinal edge of articulated slab.Notch 59 is set up in parallel and forms near one of each articulated slab 19, the 21 vertical protuberance 63 of end.Otch 61 is positioned at relatively vertically end.Protuberance 63 and otch 61 on two articulated slabs 19,21 with the reverse order setting, thereby when articulated slab 19,21 interconnected, the protuberance 63 of one of them plate was passed through by the otch 61 of second plate.This just helps metal filate spring 17 is installed to the bottom side of interconnective articulated slab 19,21, and this will be described in detail below.
Interconnective articulated slab 19,21 has formed a center hinge with pivotal axis one another along its parallel connection of interior longitudinal edge of adjoining mutually.Housing 11 receives interconnective articulated slab 19,21, thereby makes the outer longitudinal edge of each plate be arranged in the respective curved bottom frame 25 (with reference to Fig. 2 B and 3B) of housing loosely.Therefore, articulated slab 19,21 is fixed on the housing 11, but the edge can move freely in frame 25, thereby makes articulated slab 19,21 freely to pivot with respect to housing around pivotal axis.When articulated slab 19,21 pivots and when opening ring component 41, the pivotal axis upwards rising flat top portion 23 of housing (promptly towards) moves, and when plate 19,21 pivots with closed hoop parts 14, and the pivotal axis rising flat top portion 23 of housing (promptly away from) downwards is mobile.
The control structure 15 of this embodiment generally includes actuation control handle 31, carriage release lever 65 and three locking elements 51,53,55.Actuation control handle 31 is by making such as the suitable rigid material or the composite of metal or plastics etc.It comprises that the head 67 of an expansion is so that grasping control handle 31 and to its application of force.First swivel pin 69 passes the upper opening 71 that is positioned on the actuation control handle and is positioned at jut 29 on the housing 11, and control handle 31 is installed on the housing 11 to pivot with respect to housing 11.Second swivel pin 73 passes the lower openings 75 that is positioned on the actuation control handle 31 and is positioned at opening 77 on the intermediate connector 79, thereby converts the pivoting action of control handle to linear substantially carriage release lever motion.Although the motion of carriage release lever not exclusively is linear, consider that by purpose of the present invention it should be regarded as linear movement.
Referring now to Fig. 4-6, carriage release lever 65 receives the pivoting action of control handles and with respect to housing 11 and articulated slab 19,21 translations along the longitudinal direction.Carriage release lever 65 is flat strip, is made by metal or other material with enough rigidity.It is parallel to the longitudinal axis setting of housing usually, is positioned at the below of housing rising flat top portion 23 and is positioned at the top of articulated slab 19,21.Carriage release lever 65 also comprises the locking element 51 of three one, 53,55, locking element can be with carriage release lever 65 translational motions, and the position according to carriage release lever can (1) make articulated slab 19,21 pivot, with closed hoop parts 41, and the pivoting action of prevention articulated slab is with the ring component 41 of locked closed, perhaps (2) allow metal filate spring 17 to make articulated slab 19,21 pivot, to open ring component 41 (promptly, locking element 51,53,55 can with articulated slab 19,21 upper sheds 45,47,49 alignment, to allow metal filate spring 17 freely to act on articulated slab 19,21 and their are pivoted, this will be described below).
Specifically with reference to Fig. 6, in this embodiment, each locking element 51,53,55 comprises two isolated flanges 95, and flange and carriage release lever 65 are integrally formed and bend 90 ° downwards from a longitudinal edge of carriage release lever (each edge is by label 66 expressions).Correspondingly, each side of carriage release lever 65 has three flanges 95, and the flat face of each flange is parallel with the flat face of other flange and parallel with the longitudinal axis of carriage release lever 65 simultaneously.In addition, the lower limb of each flange forms with articulated slab 19,21 and combines and make the cam face 99 of their pivots with closed hoop parts 41 at angle.This angle makes that in case ring component 41 closures, locking element 51,53,55 slips into the position that ring component 41 is locked together.In addition, locking element 51,53,55 length along carriage release lever 65 are provided with at interval, and are when opening with convenient ring component 41, corresponding with second, third and the 4th opening 45,47,49 on the articulated slab 19,21.Should be understood that locking element can form single or more than two parts, and adopt control structure also not depart from the scope of the present invention greater or less than three locking elements or difform locking element.
Shown in Fig. 7-9, the metal filate spring 17 of this embodiment is circular metal lines, and its formation has the octagon (open end forms one of octagon side) of open end and closing end 17A.Closing end 17A upwards bends 90 °, so that be assemblied in the notch 59 on one of interconnective articulated slab 19,21 and be positioned at protuberance 63 tops.The free end of protuberance 63 is positioned at the rear on the bending base 25 of housing, so the closing end 17A of spring is positioned on the protuberance 63.The open end of each spring comprises two ends 101, and terminal 101 bend respectively twice and form hook-type.Wherein bending for the first time is for upwards bending 90 °, and bending for the second time is 90 ° of outwards bendings.Terminal 101 are assemblied in the otch 61 of the second interconnective articulated slab 19,21 separably, make the main body of metal filate spring 17 in fact be positioned at the below of interconnective articulated slab 19,21.When mounted, be in relaxed state, make ring component 41 open when articulated slab 19,21 is positioned to metal filate spring 17.(promptly to interconnective articulated slab 19,21 (with reference to Fig. 3 B)) bending that makes progress slightly of the main body of spring 17 makes to form angle A less than 180 ° (being the co-planar locations top that the pivot axis of articulated slab is positioned at articulated slab 19,21) between the outer surface of interconnective articulated slab 19,21.When locking element 51,53,55 moves down articulated slab 19,21 and by co-planar locations during with closed hoop parts 41 (with reference to Fig. 2 B), each crooked metal filate spring 17 becomes direct join pressurizeds.On the contrary, when locking element 51,53,55 moves to when aliging with the respective openings 45,47,49 on the articulated slab 19,21, the metal filate spring 17 of pressurized automatically acts on articulated slab 19,21 and they are upwards pivoted and by co-planar locations, opens ring component 41.Should be understood that though illustrated mechanism 1 has two metal filate springs 17, the mechanism that has greater or less than two metal filate springs does not depart from the scope of the present invention yet.
Referring now to Fig. 2 A-3B, 5 and 8-11, control structure 15 optionally controlling organization moves between closed and locked position and open position.In closed and locked position (Fig. 2 A, 2B, 5 and 8), ring component 41 combines and can not be pulled away from.In this position, the orientation of articulated slab 19,21 makes their pivotal axis be lower than co-planar locations slightly, and the angle A between outer surface 103 is in maximum.In addition, actuation control handle 31 is vertical relatively, and carriage release lever 65 positions are near housing one end with control handle 31.Like this, first, second and the 3rd locking element 51,53,55 and do not align with the respective openings 45,47,49 on the articulated slab 19,21 between articulated slab 19,21 and housing 11.At the carriage release lever locked position, because locking element is dimensioned to carriage release lever 65 and occupies zone between the rising flat top portion 23 of articulated slab 19,21 and housing fully, so locking element 51,53,55 has stoped any power that is intended to open ring component 41 securely.Therefore, when articulated slab 19,21 upwards promotes locking element 51,53,55 (when articulated slab 19,21 pivots when opening ring component 41), articulated slab 19,21 meshes with locking element 43,45,47 immediately, makes locking element 51,53,55 and carriage release lever 65 have uptrending.But the rising flat top portion of housing 23 stops these motions, thus the pivoting action of obstacle articulated slab and prevent that ring component 41 from opening.
For opening mechanism 1, the outwards also downward pivot actuation control handle 31 (Fig. 9) of operator's (not shown).This just promotes intermediate connector 79 and carriage release lever 65 away from the shell end 11a with control handle 31, and makes carriage release lever 65 translations and move apart locked position.Corresponding second, third and the 4th opening 45,47,49 that carriage release lever 65 moves on each locking element 51,53,55 and articulated slab 19,21 align.In the middle transition position, locking element 51,53,55 no longer stops the pivoting action of articulated slab.This just makes metal filate spring 17 automatically act on the articulated slab 19,21, articulated slab 19,21 is upwards pivoted and by co-planar locations (and thereby overcome any elastic force that the prevention articulated slab moves through the housing 11 of co-planar locations), make respective openings 45,47,49 pass locking element 51,53,55, and ring component 41 is opened.In open position (Fig. 3 A, 3B, 10 and 11), the cam face 99 of each locking element 51,53,55 stretches out from the respective openings 45,47,49 of articulated slab fully, and the angle A between the outer surface 103 of articulated slab is in minimum.The elastic force of metal filate spring 17 and housing makes ring component 41 stay open, and the operator can let go control handle 31 and increase for mechanism 1 or the taking-up page.
In order to make mechanism 1 get back to closed and locked position, the operator inwardly and the actuation control handle 31 (Fig. 2 A, 5 and 8) that upwards pivots.This just pulls back intermediate connector 79 and carriage release lever 65 to the shell end that control handle 31 is housed, and causes the cam face 99 and the edge engagement of articulated slab 19,21 in respective openings 45,47,49 of locking element.When the operator continues to pivot control handle 31 and mobile carriage release lever 65, locking element 51,53,55 begins to make articulated slab 19,21 to pivot, and therefore overcome the power that stops articulated slab 19,21 motions (be locking element cam face 99 and the force of sliding friction between the articulated slab 19,21, metal filate spring prevention its become the housing elastic force that straight power and prevention articulated slab move through co-planar locations).Thereby articulated slab 19,21 is at leisure to each cam face 99 of lower slider, and makes ring component 41 move together lightly.In case ring component 41 is closed fully, carriage release lever 65 is got back to locked position, and locking element 51,53,55 is got back to the position that stops the articulated slab pivoting action fully.As mentioned above, in mechanism 1, locking element 51,53,55 bias voltage articulated slabs 19,21, they are pivoted only is for closure and locking ring parts 41. Locking element 51,53,55 can not mobile hinge fishplate bar 19,21 to open ring component 41.This is realized by metal filate spring 17.
When ring component 41 closures, circular clip mechanism of the present invention keeps loose leaf paper reliably.In this position, locking element 51,53,55 and carriage release lever 65 have occupied the zone between the rising flat top portion 23 of articulated slab 19,21 and housing substantially fully, and locking element 51,53,55 be positioned at substantially with articulated slab 19,21 on the position that do not line up of respective openings 45,47,49.In addition, housing 11 surrounds locking element 51,53,55, thereby has formed a barrier, in case external force makes locking element 51,53,55 unexpected moving and aligns with opening 45,47,49.Therefore, carriage release lever 65 and locking element 51,53,55 can stop any hinge plate motion that is intended to open ring component 41 fully, and can make that ring component locks together reliably, thereby have reduced the chance that mechanism's accident is opened.In addition, when ring component 41 was full of page, mechanism 1 was easy to control.Directly lock together differently with the ring component self of prior art, control handle 31 can make locking element 51,53,55 move to open ring component 41.And because locking element 51,53,55 equably along the length direction of articulated slab 19,21 at interval, so the locking element 51,53,55 of this mechanism is uniformly distributed to ring component 41 substantially with latching force and makes gap minimum between the closed hoop parts 41.
Because the pivoting action of the cam face 99 control articulated slabs 19,21 of locking element, so mechanism 1 can also alleviate undesirable unexpected snap-action when ring component 41 closures.When the operator pivots actuation control handle 31 during with closed hoop parts 41, locking element 51,53,55 is mobile hinge fishplate bar 19,21 at leisure, thereby gently with ring component 41 bands together.Metal filate spring 17 articulated slab 19,21 is upwards pivoted and by co-planar locations to open ring component 41.In this case, metal filate spring 17 has been carried out and housing elastic force identical functions effectively.Therefore, the elastic force of housing can reduce or eliminate, thereby makes to have only metal filate spring 17 to act on the articulated slab 19,21.When this just made ring component 41 closures, articulated slab 19,21 can more be easy to move down and pass through co-planar locations.
In addition, mechanism 1 open more easy than prior art.At locking element 51,53,55 with before the respective openings 45,47,49 on the articulated slab 19,21 is alignd, the operator only need make that carriage release lever 65 moves than short distance, metal filate spring 17 automatically acts on articulated slab 19,21, and they are pivoted to open ring component 41.Similarly, because the mechanical property that control handle 31 is had, the pivoting action of its control handle has reduced the size that makes carriage release lever move required power.
Referring now to Figure 12, show another form with the carriage release lever of label 105 expressions.Carriage release lever 105 comprises three juts that are integrally formed therewith 107 (only showing among the figure).Each jut 107 is from 90 ° of the downward bendings in the surface of bar and can receive locking element 111, and locking element 111 forms dividually and is fixed on the jut 107 with carriage release lever 105 in this embodiment.Locking element 111 is generally block and can and can wedges articulated slab 19,21 to make with the plastics that ring component 41 is moved together or other material that is fit to by the pivoting action that can stop articulated slab.Be similar to the cam face 99 of the carriage release lever of first embodiment, locking element 111 has an angled cam face 113.Therefore, each embodiment described herein can comprise the carriage release lever 105 of this a kind of version.
Figure 13 A-14B shows second embodiment of circular clip mechanism of the present invention.The mechanism of this embodiment is with label 201 expressions.Parts corresponding to those in the first embodiment adopt identical label to add " 200 " expression in the mechanism of second embodiment.This embodiment and first embodiment are similar, but do not have metal filate spring below articulated slab.In this embodiment, the elastic force of housing 211 pivots to open ring component 241 articulated slab 219,221.Articulated slab 219,221 pivots in housing 211, therefore when ring component 241 is mobile between closure and open position, pivot axis never can move (that is, the angle A between the outer surface of articulated slab (Figure 13 B and 14B) is always less than 180 °) below co-planar locations.Therefore, the elastic force of housing only plays the effect of opening ring component 241 and will never the closed hoop parts.In addition in this embodiment, owing to do not use metal filate spring, articulated slab 219,221 does not comprise the notch or the otch of longitudinal edge outside them.But in others, the articulated slab 219,221 of this embodiment is identical with the articulated slab 19,21 of first embodiment.
Figure 15-17 shows third embodiment of the invention.Mechanism of the present invention represents with label 401.This embodiment part corresponding to those in the first embodiment adopts identical label to add " 400 " expression.The something in common of this embodiment and second embodiment is, housing 411 bloster hinge fishplate bars 419,421 move pivotally, make that the pivot axis of articulated slab 419,421 can not move to or be lower than co-planar locations when ring component 441 is mobile between closing position and open position.But opening 516 places of the control handle 431 of control structure 415 on the housing flat top portion 423 between the end of two symmetries of housing 411 in this embodiment.For this reason, housing 411 comprises from rising flat top portion 423 upwardly extending two juts 515.Jut 515 can receive swivel pin 517, so that control handle 431 is installed on the housing 411 pivotally.In this embodiment, control handle 431 is elongated bow beam, and it comprises web and two side flanges that bend downwards.At one end, side flange is apered to web, forms plane surface 523 so that the grasping and the control handle 431 that pivots.At the other end, cam face 525 stretches out downwards from side flange.Still at this end, two side flanges are passed in hole 527, are used to receive control handle 431 is installed in swivel pin 517 on the housing 411.
The structure 401 of this embodiment does not adopt the intermediate connector that the pivoting action of control handle is converted to the linear movement of carriage release lever.Alternatively, the cam face 525 of control handle is assemblied on the carriage release lever 465 between the relative shoulder 529 that forms loosely, makes the pivoting action of control handle directly with respect to housing 411 translation carriage release levers 465.Each cam face 525 allows cam face 525 to be pivoted and on one or another shoulder 529 in the loose fit between the corresponding a pair of shoulder 529, thus mobile linearly carriage release lever 465.Shoulder 529 is along the end setting near carriage release levers 465 of the longitudinal edge 466 of carriage release lever, and is arranged so that a shoulder 529 is directly relative with another shoulder.Each shoulder 529 forms for 90 ° by making two relatively partly downward bendings, so the plane of each part is vertical with carriage release lever 465.In this embodiment, owing to do not adopt the intermediate connector that receives carriage release lever 465, carriage release lever 465 does not have end flange or slit.
Specifically with reference to Figure 16 A-17, the operation of this embodiment is in fact similar with the operation of second embodiment.At the closed and locked position shown in Figure 16 A, control handle 431 is level and be parallel to the rising flat top portion 423 of housing substantially but in this embodiment.In order to open ring component 441, the operator is (promptly towards ring component to 441 center) pivot control handle 431 upwards and inwardly.The cam face 525 of control handle is with 529 engagements of the shoulder of carriage release lever and make carriage release lever 465 towards control handle 431 linear movements.This moves locking element 511 and aligns with the respective openings 445,447,449 on the articulated slab, thereby permission housing elastic force pivots articulated slab 419,421 and opens ring component 441.Articulated slab 419,421 comprises between the second and the 3rd opening 445,447 additional opening 531, is used to receive pass the control handle cam face 525 that interconnects articulated slab 419,421 and the shoulder 529 (accompanying drawing 17) of carriage release lever.Therefore, during operation, do not have between articulated slab 419,421 and control handle 431 or the carriage release lever 465 and interfere.For closed hoop parts 441, the operator is pivot control handle 431 downwards and outwards, and is opposite with opening operation, make cam face 525 once more against shoulder 529 so that carriage release lever 465 moves apart control handle 431.As second embodiment, the cam face 513 of each locking element 511 is with articulated slab 419,421 engagements and they are pivoted with closed hoop parts 441, and cam face is identical with the cam face 113 of the locking element of the carriage release lever 105 of the another kind of version of above-mentioned employing in this embodiment.Should be understood that although housing elastic force makes articulated slab 419,421 pivot to open ring component 441 in this embodiment, metal filate spring also can be installed to the bottom side of articulated slab selectively, so that as described in first embodiment, articulated slab is pivoted.
Figure 18-21D has shown the circular clip mechanism according to fourth embodiment of the invention.This mechanism is by label 401 ' expression, and identical substantially with the mechanism 401 of the 3rd embodiment.Mechanism 401 ' and mechanism 401 corresponding parts adopt identical label to add main symbolic representation.Mechanism 401 ' comprises and described control structure 415 similar control structures 415 '.Shown in Figure 18-19B, control structure 415 ' comprises control handle 413 ', carriage release lever 465 ' and three locking elements (each locking element is with 511 ' expression, and each control structure assembly is represented by its label substantially).But control handle 431 ' and carriage release lever 465 ' are improved slightly.Specifically be, control handle comprises the opening 432 ' that is used to receive by its erection column 437 ' that passes, make mechanism 401 ' can be installed on the loose-leaf binder front cover and do not disturb control handle 431 ', carriage release lever 465 ' to comprise reinforcement structure or rib 530 ', 533 ' along its longitudinal edge 466 '.As shown in the figure, rib 530 ' plays a part to be used to receive a pair of shoulder of the cam face 525 ' of control handle 431 ', and rib 533 ' plays a part to be used to receive the bearing of locking element 511 '.It should be understood that rib 530 ' has shoulder 529 identical functions with described carriage release lever 465 substantially, but be reinforced.
Rib 530 ', 533 ' is to form by the part that the top surface from carriage release lever bends the longitudinal edge 466 ' of carriage release lever 465 ' downwards.To be described in more detail this below.Preferably shown in the bottom perspective view of Figure 20, rib 530 ', 533 ' is bent about 90 ° downwards respectively becomes slotted shape.Rib 530 ', 533 ' comprise in the face of two shortwall parts 540 ' of the longitudinal end of carriage release lever 465 ' and in the face of the longitudinal edge of carriage release lever 465 ' than longwell part 542 '.The height H of each rib 530 ', 533 ' ' be equal to or greater than the thickness of carriage release lever 465 ', and each rib has about equal height.More specifically, the height H of each rib 530 ', 533 ' ' between about 0.05 inch (0.127cm) and 0.20 inch (0.508cm), and shown in approximately be 0.125 inch (0.3175cm) in the carriage release lever 465 '.It should be understood that its rib of strengthening carriage release lever have inhomogeneous height, different ribs have differing heights or rib have with shown in the mechanism of differing heights do not break away from the scope of the invention yet.Although in a preferred embodiment, rib and carriage release lever form, and the mechanism that rib and carriage release lever form does not dividually break away from the scope of the invention yet.
Figure 20 has shown that carriage release lever 465 ' comprises two ribs 530 ' and six ribs 533 ', and they laterally relatively are provided with respectively in pairs, make a rib of every centering be positioned on the relative longitudinal edge 466 ' of carriage release lever 465 '.For convenience's sake, the rib 530 ', 533 ' of every centering and their part are used letter " a " and " b " expression in the drawings, and this does not need the directed especially of rib.Rib 533 ' is evenly spaced apart along carriage release lever 465 ', makes them be close to ring component 441 ' (Figure 18) substantially.Rib 530 ' is provided with inside towards an end of carriage release lever 465 ' and the end of rib 533 ' spaced apartly, be positioned at the opening 516 ' positions aligning with housing rising flat top portion 423 ' substantially, with help to pass housing 411 ' place control handle 431 ' and with carriage release lever 465 ' engagement.It should be understood that have with shown in the mechanism of carriage release lever of rib of different numbers do not break away from the scope of the invention yet.
The locking element 511 ' that is received by rib 533 ' is also shown among Figure 20.As previous embodiment, use three locking elements 511 ', they move and with by otch 445a ', 445b ', 447a ', 447b ', 449a ', 449b ' goes up the register that forms or does not line up (Figure 18) at interconnective articulated slab 419 ', 421 ', with open and close ring component 441 '.As shown in the figure, each locking element is wedge-type shape and comprises angled cam face 513 ' that cam face 513 ' has same function with the cam face 513 of each locking element 511 of described mechanism 401 substantially.Tongue-like part 535 ' is arranged in that locking element 511 ' is gone up and cam face 513 ' opposite side and be recessed in locking element in the locking element both sides.As shown in the figure, the size and dimension of tongue-like part 535 ' is chosen to provide firm assembling in paired respective ribs 533 ' for each locking element 511 ', thereby each locking element is installed on the carriage release lever 465 '.Have greater or less than three locking elements or locking element and carriage release lever all-in-one-piece mechanism and also do not break away from the scope of the invention.
Figure 21 A-21D has schematically shown the formation of carriage release lever 465 ' the reinforcement structure (being rib 533a ', 533b ') of mechanism 401 '.Particularly, shown that schematically the longitudinal edge 466 ' at carriage release lever 465 ' forms a pair of rib 533a ', 533b '.As shown in the figure, carriage release lever 465 ' is made by straight substantially, the thin material piece (for example sheet metal) 522 ' shown in Figure 21 A.The part of the side by the stamping material sheet goes up spaced positions in material piece 522 ' and forms indent 526 ' is installed.Two complete sum indents 526 ' and one and half indent 526b ' in Figure 21 A, have been shown.Indent 526 ' does not penetrate or passes through material piece 522 ' when forming, but material piece is out of shape in the circular arc mode.Known process for stamping in metal processing can be used for forming indent 526 '.Use other method except that process for stamping also not break away from the scope of the invention.
As shown in the figure, each indent is identical substantially.Each has elongated shape, and the cross section that intercepts along the direction that is transverse to the indent longitudinal axis is a bowed shape.Still as shown in the figure, especially by comparison diagram 21A and 21D, contiguous indent 526 ' is gone up with distance W in material piece 522 ' ' spaced (center to center at interval), distance W ' approximates the width W ' of the carriage release lever 465 ' of each formation greatly.
With reference to Figure 21 A and 21B, go up in material piece 522 ' and to form adjacent indent 526 ' afterwards, substantially along the longitudinal axis cutting material sheet of each indent.Cutting is by passing through shown in the dotted line of indent 526 ' among Figure 21 A.Cutting forms the elongated substantially rectangle material band (Figure 21 B) as carriage release lever 465 ', and each indent is divided equally into two and half indent 526a ', 526b '.Half indent of each indent is symmetrical substantially, and is positioned at the relative longitudinal edge (Figure 21 B and 21C) of the carriage release lever 465 ' of continuous formation.Therefore each carriage release lever comprises half indent 526a ' of first indent 526 ' and half indent 526b ' of adjacent second indent.
Referring now to Figure 21 B-21D, the edge 466 ' by and/or folding carriage release lever 465 ' crooked at half indent place is with half indent 526a ', and 526b ' forms rib 533a ', 533b '.Known method for metal working can be used for forming each rib 533a ', the wall part 540a ' of 533b ', 540b ', 542a ', 542b '.Although Figure 21 A-21D has shown rib 533a ', the formation of 533b ' it should be understood that to form rib 530a ', 530b ' in the same manner.In addition, although only shown a pair of rib 533a ', the formation of 533b ' it should be understood that can come material piece 522 ' along the longitudinal goes up a plurality of indents 526 ' of formation.In every row, the alignment of the longitudinal axis of a plurality of indents.Also can go up and form many row pressures groove 526 ', adjacent row's corresponding indent lateral separation distance W ' in material piece 522 '.Like this, can form a plurality of have a plurality of rib 530a ', 530b ', 533a ', the reinforcement carriage release levers 465 ' of 533b ' from material piece 522 '.Be exemplified as the carriage release lever 465 ' that is presented among Figure 20.It should be understood that when forming reinforcement carriage release lever of the present invention 465 ', can be in first procedure of processing go up and form indent 526 ' and be delivered to cutting step subsequently in material piece 522 '.And, also can just before cutting, go up formation indent 526 ' in material piece 522 ', make them carry out in the same step substantially.
It is useful that the rib 533 ' of carriage release lever 465 ' has following reason at least.They are slotted shape, thereby provide thicker carriage release lever size in the rib present position.This helps to strengthen carriage release lever 465 ', to stop around the axis bending of carriage release lever longitudinal extension and to stop axis bending around the carriage release lever width.Because rib 533 ' is corresponding to the position of locking element 511 ', the thickness that increases in these positions improves carriage release lever when meshing repeatedly with articulated slab 419 ', 421 ' in operating process non-deformability is favourable.Therefore, carriage release lever 465 ' of the present invention not yielding and inefficacy after using repeatedly.The circular clip mechanism that comprises this carriage release lever is more durable.Therefore, the problem that can avoid carriage release lever distortion to be produced can not make articulated slab pivot with the closed hoop parts fully, can not be fully the ring component of closure be moved together preventing and produce the gap between the closed hoop parts, maybe the ring component of closure can not be locked together such as carriage release lever.
Flute profile rib 533 ' has also improved the coupling mechanism force that closed hoop parts 441 ' are locked together.As previous description to control structure 415, when control structure 415 ' is included in the mechanism 401 ' and mechanism when being in closed and locked position, can stop the pivot-hinge fishplate bar 419 ', 421 ' that is tending towards making progress to open any power of ring component 441 ' by locking element 511 ', carriage release lever 465 ' and housing 411 '.Because ribs 533 ' is positioned at locking element 511 ' and locates, and has improved resistance, thereby prevent that carriage release lever 465 ' from unexpectedly bending at the locking element place when articulated slab 419 ', 421 ' moves upward.Therefore, control structure 415 ' can stand to be tending towards to open locking ring component 441 ' more energetically, and can not damage circular clip mechanism 401 '.
Rib 530 ' also is of value to for carriage release lever 465 ' provides improved intensity and moves to stop control handle repeatedly.In operating process, the cam face 525 ' of control handle 431 ' meshes the shortwall part 540 ' of rib 530 ' repeatedly, drives carriage release lever 465 ' with the longitudinal direction along housing 411 '.The slotted shape of rib 530 ' has been improved the resistance to these driving forces, because the shortwall part of rib 540 ' is by slotted shape (that is, than the longwell part) connection of rib 530 '.This has stoped shortwall part 540 ' crooked or distortion when repeatable operation, and this may occur in the mechanism of prior art, and control handle cam face bias voltage is by the single relative shoulder of carriage release lever cutting and bending in the mechanism of prior art.
Another advantage of rib 530 ', 533 ' is to form rib by the part of downward bending carriage release lever 465 '.Because the rib 530 ', 533 ' and the carriage release lever of bending are integral, this has increased the bulk strength of carriage release lever 465 '.Therefore, after forming, rib 530 ', 533 ' has kept a lot of inherent strength of materials of carriage release lever 465 '.On the contrary, form similar reinforcement structure by a part of cutting carriage release lever and can weaken carriage release lever, make carriage release lever in fact lose intensity in incision.And rib 530 ', 533 ' provides intensity and the certain stiffness that do not need to increase the whole thickness of carriage release lever 465 ' or do not need to be used for carriage release lever is handled.
With reference to Figure 22 and 23, shown substantially by label 401 " expression fifth embodiment of the invention.Mechanism 401 " mechanism 401 is identical substantially once more.Mechanism 401 " adopt identical label to add two main symbolic representations with mechanism 401 corresponding parts.Shown mechanism 401 " carriage release lever 465 ", wherein locking element is with 511 " form with carriage release lever.More specifically, locking element 511 " by carriage release lever 465 " rib 533 " form.Here, each rib 533 " height H " be uneven, make each rib 533 " angled; thereby make it play cam face 513 ", every couple of respective ribs 533a ", 533b " as a locking element 511 " with operating mechanism 401 " (each rib 530 " rib 530 ' identical of height and described mechanism 401 ').It should be understood that without departing from the present invention each mechanism described here can be modified to comprise and be similar to carriage release lever 465 " the reinforcement carriage release lever.
According to the parts of the circular clip mechanism of the present invention of described several embodiment by making such as the suitable rigid material of metal (for example steel).But by nonmetallic materials particularly the plastics mechanism of making do not depart from the scope of the present invention yet.
When introducing the element of the present invention or most preferred embodiment, article " ", " being somebody's turn to do " and " described " means that one or more elements are arranged.Term " comprises " that " comprising " and " having " is meant to comprise and mean also have other parts except components listed.In addition, this is employed " on ", the distortion of D score and these terms just for convenience, and need not the concrete arbitrarily location of element.
Because above-mentioned various distortion all can be made not breaking away under the scope of the invention, therefore above literal and all the elements shown in the drawings all should regard a kind of as and schematically and not should regard a kind of restriction as.
