Detailed description of the invention

With reference to accompanying drawing, Fig. 1 to Fig. 5 illustrates the embodiment of ring loose-leaf binder mechanism of the present invention, and it is roughly designated as 101.In FIG, mechanism 101 is arranged on notebook cover 103.Particularly, mechanism 101 is installed as the ridge 105 of contiguous notebook cover 103.Ridge 105 extends hinged being attached between the front cover 107 of ridge 105 and back cover 109.Front cover 107 and back cover 109 removable optionally to cover or to expose the loose-leaf (not shown) fixed by mechanism 101.Otherwise (such as, on ridge) is arranged on notebook cover or the ring loose-leaf binder mechanism be arranged on the substrate (such as, file, briefcase etc.) except notebook cover does not depart from category of the present invention.

As shown in Fig. 2 to Fig. 5, mechanism 101 comprises the elongated envelope 111 supporting multiple ring (each ring is roughly labeled as 113).Shell 111 also has projection flat central platform 117 and from the opposite flank of platform and the side direction phase epitaxy side 119 of stretching downwards.The side 119 of shell is substantially parallel to each other.Roughly arched cross-section shape is given for shell in platform 117 and side 119.The flatness of platform 117 and side 119 makes the arched cross-section shape of shell 111 illustrated in Fig. 1 and Fig. 6 become segmentation and have angle arch.But, should be appreciated that the side of shell and center top part can bend more smoothly in category of the present invention.In the embodiment shown in the drawing, first of shell 111 longitudinal end 121 roughly open and second, relatively longitudinal end 123 is roughly closed.Bending lower edge 125 extends along the exterior rim lengthwise of the side 119 of shell 111.There is the mechanism of the shell of the shape different from shell 111 illustrated in accompanying drawing in category of the present invention.

Ring 113 can operate with in the ring mechanism 101 be fixed on by loose-leaf in notebook 103.Ring mechanism 101 illustrated in accompanying drawing has three rings 113.But, in category of the present invention, ring variable amounts.Ring 113 shown in the drawings is mutually the same in fact and shape is respectively circular.As shown in Fig. 1 to Fig. 6, ring 113 respectively comprises two collar member 133(and is sometimes referred to as and is labeled as 133a and 133b to refer to specific of paired collar member).Collar member 133 by having the routine of suitable material (such as, steel) of circular cross sectional shape, cylindrical bar suitably formed.The ring loose-leaf binder mechanism with the collar member being formed by different materials or have varying cross-section shape (such as, elliptical cross sectional shape) does not depart from category of the present invention.In the embodiment shown in the drawing, collar member 133 is that roughly semicircle makes ring 113 have circular shape, but ring can have non-circular shape in category of the present invention.In addition, one of collar member can have the shape different from another, the situation of such as D shape ring and other asymmetric ring.

At least one of the collar member 133a of each ring 113 can move relative to shell 111 and opposed rim component 133b can move between closing position and open position.In ring mechanism 101 in the accompanying drawings, two collar member 133a, 133b respectively move with open and close ring 113 relative to shell 111 with essence similar fashion, but this is not that to put into practice the present invention necessary.Such as, in category of the present invention, one of collar member of each ring can be fixed to shell.In closing position (Fig. 2), collar member 133 forms continuous in fact, the closed loop allowing the loose-leaf fixed by ring 113 to move to another collar member along ring from a collar member.In open position (Fig. 4), collar member 133 forms discontinuous, the open loop that are used for adding or remove loose-leaf from ring 113.

Ring mechanism 101 comprises the identical flap 127 of two essence supporting collar member 133.The shape of flap 127 is respectively roughly microscler, smooth and rectangle and each shorter than shell 111 a little in length.Flap 127 along its in longitudinal rim with configured in parallel interconnection (as illustrated in Fig. 3 and Fig. 5), it forms the center hinge 145 with pivot.This suitably completes with usual manner as known in the art.Outer longitudinal rim of flap 127 is received in the groove formed by the bending lower edge 125 of shell 111, its thus bloster hinge carrier bar with pivotable in the enclosure.As shown in Figure 6, collar member 133a, 133b are respectively arranged on respective upper (it is labeled as 127a and 127b sometimes with corresponding with the mark of respective collar member) of flap 127 with roughly relative mode.Collar member 133 extends through respective opening 155 along the side 119 of shell 111 and makes when ring 113 closes, and the free end of collar member is engaged with each other above shell.Collar member 133 is rigidly connected to flap 127 and moves with flap when flap pivotable.In ring loose-leaf binder mechanism 101 illustrated in the accompanying drawings, two collar member 133 of installing each ring 113 make its upper surface from flap 127 extend.But, mechanism's (such as, as disclosed in No. 20080008519th, the US publication application case owned together) that one or more collar member makes its lower surface from flap extend wherein is installed also in category of the present invention.

Flap 127 can in center hinge 145 relative to shell 111 downwards and upwards pivotable with the collar member 133 be installed on it mobile between closing position and open position.When flap 127 downward pivotable (that is, center hinge 145 moves apart shell 111), collar member 133 closes.When flap 127 upwards pivotable (that is, center hinge chain rivet 145 moves towards shell 111) time, collar member 133 is opened.When flap is in co-planar locations, the combined width of flap 127 than shell 111 bending lower edge 125 between interval wide.Therefore, when flap 127 pivot through co-planar locations, flap makes shell 111 be out of shape and form spring force in shell.Shell spring force flap 127 and ring 113 in the close position time, biasing hinge plate 127 and ring 113 with remain closed and flap and ring in an open position time, biasing hinge plate and ring are to stay open.

Actuator 115 can be moved to cause flap 127 to move pivotally against the spring force from shell 111 with open and close ring 113 relative to shell 111 by user.Actuator 115 can rotate between collar member 133 is in the close position wherein primary importance (Figure 11) and the second place (Fig. 9) that wherein collar member is in an open position.

In the embodiment shown in the drawing, actuator 115 is mounted to be formed separately by shell 111 and (such as, by one or more rivet or other suitable securing member) is fixed to lever support 171(Fig. 6 of shell) on relative to shell between the open position and the closed position pivotable move.The openend 121 that lever support 171 is included in shell 111 is positioned at the plate 175 on enclosure platforms 117 top.Lever support 171 also has the arm 177 extended to from the opposite side of plate 175 through groove 179 on the end 121 of shell shell 111.Actuator 115 is connected to lever support pivotly by extend through the pivot pin 181 of actuator and is fixed by the arm of lever support.Therefore, actuator 115 is around the pivot pivotable overlapped with pin 181.Lever support 171 does not extend longitudinally beyond the openend 121 of shell 111.In addition, when ring closes, only the relative tiny segment of actuator 115 extends longitudinally beyond the openend 121 of shell 111.The alternate manner (be included in and be directly mounted to shell without when independent lever support) installing actuator does not depart from category of the present invention.

Refer now to Fig. 8 to Figure 11, the closure arm 203 that actuator 115 has main body 201 and extends from main body.Closure arm 203 is located pivot-hinge carrier bar 127 and when actuator moves to closing position from open position, ring 113 is moved to closing position.Actuator 115 also has and to extend from main body 201 and located pivot-hinge carrier bar 127 and when actuator moves to open position from closing position, ring 113 moved to the opening arms 205 of open position.As Fig. 8 and seen in fig. 9, closure arm 203 and opening arms 205 form passage 207, wherein receive the end of flap 127.Handle 211 extends to promote by user's movement actuator between the open position and the closed position from the main body 201 of actuator 115.In category of the present invention, the handle of actuator can have many difformities.

The end of flap 127 is received in passage 207 and closure arm 203 is positioned at above flap end and opening arms 205 is positioned at below flap end.Each flap 127 has relative narrower finger piece 141(Fig. 6 extending longitudinally towards the openend 121 of shell 111).The width of finger piece 141 is respectively narrow than respective flap 127 and located longitudinal edge in it is roughly alignd with longitudinal edge in flap and center hinge 145.When actuator 115 moves to open position from closing position, opening arms 205 applies the finger piece 141 of upward force to flap, its by center hinge 145 upwards pivotable to open ring 113.Similarly, when actuator moves to closing position from open position, closure arm 203 applies downward force to finger piece 141, its by center hinge 145 downwards pivotable with closed ring 113.Suitably, opening arms 205 and flap 127 constant contact.

Except open and close ring 113 described above, actuator 115 is also adjusted when actuator moves with open and close ring 113 between its open position and closing position, mobile locking member 221 between latched position (Figure 11) and non-locked position (Fig. 9).In latched position, locking member 221 prevents ring 113 from moving to open position from closing position by stopping the pivoting action of flap 127.In non-locked position, locking member 221 does not stop that flap 127 and ring 113 move to open position from closing position.Suitably, while locking member 221 is moved out of latched position, actuator 115 makes flap 127 be out of shape sequentially to move locking member and flap.

As illustrated in fig. 7, locking member 221 is one of three essence same lock elements on the sticking department 223 of motion bar 225 (its each be labeled as 221), and it is extending longitudinally between the flap 127 of shell and platform 117 in shell 111.The variable amounts of locking member and do not depart from category of the present invention.Locking member 221 is opened along sticking department 223 longitudinal subdivision of motion bar 225, each longitudinal end of the sticking department 223 of the contiguous motion bar of locking member and a centralized positioning towards the sticking department of motion bar.Locking member 221 is given prominence to from the sticking department 223 of motion bar 225 towards flap 127.As shown in FIG. 9 to 11, each locking member 221 comprises flat bottom 271, inclination forward edge 273 and backward extension 275.The sloping edge 273 of locking member 221 can joint hinge plate 127 and assist the center hinge 145 of downward pivot-hinge carrier bar at period of contact.In the embodiment shown in the drawing, locking member 221 is made to be integrally formed as the from one piece with motion bar 225 by such as injection moulding technique.But locking member can be formed in motion bar separately and be attached to motion bar and do not depart from category of the present invention.In addition, there is the locking member of difformity (such as, block (such as, non-angular edge)) in category of the present invention.Motion bar 225 and locking member 221 can be referred to as " locking system ".

Otch 129(Fig. 3 and Fig. 6) be formed in each flap 127 along the inside rim of plate.As illustrated best in Fig. 3, the otch 129 in each indivedual flap 127 aims to form four openings (being also labeled as 129) along the center hinge 145 of interconnecting hinge plate.Erection column 151 penetrates one of opening 129 in the flap 127 of the openend 121 of adjacent housings 111.Three other openings 129 are along center hinge chain rivet 145 axial location of the flap 127 of approach locking element 221.Particularly, opening 129 to be located so that when motion bar 225 is in non-locked position (Fig. 9) it is aimed at locking member 221 and therefore when motion bar is in latched position (Figure 11), it is not aimed at locking member.As illustrated in fig. 11, when motion bar 225 is in latched position, the upper surface of flat bottom 271 joint hinge plate 127 on the edge of opening 129 of locking member 221 and stop that flap moves towards its open position pivotable thus.

The sticking department 223 of motion bar is connected to actuator 115 by the connecting portion 227 of motion bar 225.The connecting portion 227 of motion bar 225 by hinge 229(such as, hinges) be suitably attached to sticking department 223, described hinge 229 allows connecting portion to move to promote that the motion of connecting portion (it can be driven in the mode comprising some rotations by actuator 115) is converted into the Linear-moving of the sticking department of motion bar relative to sticking department pivotable.Hinge 229 such as suitably has the flexibility larger than the connecting portion 227 of motion bar 225 because hinge structure is the section of the motion bar of the reduction thickness had relative to connecting portion 227.

With reference to figure 6 and Fig. 7, the end of the connecting portion 227 of the motion bar 225 relative with hinge 229 is positioned on the openend 121 of shell.The end of connecting portion 227 have along shell 111 towards openend 121 arm 231 extending longitudinally and be positioned at motion bar 225 end on and the cross bar 233 extended between the arms.Catch cross bar 233 by actuator 115 and make the actuator movement of mobile generation cross bar 233 on motion bar 225 end between the open position and the closed position.

With reference to figure 8 to Figure 11, as illustrated in fig. 8, there is groove or the recess 255 of the cross bar 233 wherein can caught on motion bar 225 end.In the embodiment shown in the drawing, recess 255 is between closure arm 203 and handle 211.When the cross bar 233 of motion bar 225 is captured in recess 255 by actuator 115, cross bar extends through the opposite side of recess to actuator from the side of actuator.A part for recess is defined by concave surface 265, and described concave surface 265 is configured as the shape roughly meeting cross bar 233 and is located in against described concave surface with promotion cross bar during opening.Another part of recess is defined by concave surface 251, and described concave surface 251 is configured as the shape that roughly meets cross bar 233 to promote that cross bar is located in against described surface at period of contact.

Motion bar 225 and actuator 115 adjusted make between ring mechanism 101 erecting stage by the direction of the longitudinal axis being approximately perpendicular to cross bar (such as, approximately towards under) move cross bar relative to actuator and cross bar 233 be clipped in recess 255.This may be favourable, because it promotes that wherein cross bar 233 and the remainder of connecting portion 227 are integrally formed as the use of the motion bar 225 of single-piece.It also may be favourable, because as needed when longitudinally inserting approximately with the pin in the opening of the structure formed objects that will insert wherein or other elongate structure in the assembling of motion bar and actuator, different assembly is without the need to Accurate align and insert other assembly.This simplify the assembling of ring mechanism 101.

Envision whole actuator 115(except the optional liner (not shown) that may cover some or all of handle 211) be integrally formed as single-piece (such as, being formed by the plastic polymeric material of elasticity).But in category of the present invention, actuator 115 can be formed by other material or by other technique.Such as, by being formed separately and assembling the actuator made with the assembly producing actuator in category of the present invention.Have and do not depart from category of the present invention with the ring mechanism of variform actuator shown and described herein.

Except locking member 221, the sticking department 223 of motion bar 225 also comprises the fixing formation 239 of the corresponding fixing formation 241 be configured on splice closure 111.Fixing formation 239,241 is configured to help when ring 113 closes motion bar 225 to be remained on latched position and helps when ring is opened motion bar to remain on non-locked position.Fixing formation 239,241 also provides sense of touch and audio feedback to the user of manipulation actuator 115, and the movement between the open position and the closed position of instruction actuator completes.In addition, when ring closes, the fixing formation 239,241 in illustrated embodiment can be used for applying tension force to motion bar actuator is pulled to its closing position with ring 113 is closed always.

In the embodiment shown in the drawing, motion bar 225 and shell 111 respectively comprise the identical fixing formation 239,241 of a pair essence, and it is longitudinal subdivision each other respectively.Such as, at least one locking member 221 on motion bar 225 is suitably positioned between two fixing formations 239 on motion bar.Similarly, at least one ring 113 is suitably positioned between the fixing formation 241 on shell 111.Although in the embodiment shown in the drawing, motion bar 225 and shell 111 respectively have a pair fixing formation 239,241, and should be appreciated that in broad scope of the present invention, motion bar and shell may only include single fixing formation.In addition, in broad scope of the present invention, motion bar and shell also can comprise more than two fixing formations.

Because the fixing formation in illustrated embodiment 239,241 is identical in fact, so the detailed description of one group of fixing formation 239,241 of cooperation will be enough to describe all fixing formations.If Fig. 9 is to seen in fig. 11, the fixing formation 241 on shell 111 suitably comprises from the platform 117 of shell towards motion bar 225 and the pallet towards flap 127 to downward-extension 159.As diagram, pallet 159 can be integrally formed with shell 111, or in category of the present invention, it can be made up of the discrete item being fixed to shell.As shown in FIG. 9 to 11, pallet 159 is the circular teats (such as, scrobicula) from shell to downward-extension.But there is the pallet of difformity (such as having the convex (such as, non-circular) of sloping edge) in broad scope of the present invention.

Fixing formation 239 on motion bar 225 suitably comprises the recess 235 on the upper surface of motion bar, and described recess 235 is located receives pallet 159 when motion bar 225 is in latched position.As illustrated in fig. 7, the fixing formation 239 on motion bar 225 comprises a pair recess 235, and it comprises the first recess 235a and the second recess 235b.Second recess 235b orientates as than the first recess 235a closer to actuator 115.As actuator 115 (Figure 11) in the close position, the pallet 159 of shell 111 is received in the second recess 235b.As actuator (Fig. 9) in an open position, the pallet 159 of shell 111 is received in the first recess 235a.Recess 235 and locking member 221 are separated.Each recess 235 is suitably circular, but other shape is in category of the present invention.

As illustrated in fig. 7, motion bar 225 be included in each fixing formation 239 position on from the projection 237 to downward-extension on the downside of it.Therefore, exist on motion bar wherein in the illustrated embodiment of two fixing formations 239, there is the identical projection 237 of two essence to downward-extension on the downside of motion bar 225 on the position of fixing formation.Projection 237 provides additional thickness to make motion bar not too thin on recess 235 position of fixing formation 239 in motion bar 225.

Fixing formation 239 on motion bar also comprises the teat 245 separated with the second recess 235b by the first recess 235a.Teat 245 forms the base section of the adjacent side of recess 235.The tip 247 of teat 245 suitably with the upper surface roughly concordant (Fig. 9) of the remainder of the motion bar 225 of contiguous recess 235.As illustrated in figure 10, motion bar 225 is adjusted makes described motion bar 225 move between the open position and the closed position along with motion bar, teat 245 aligns with pallet 159 and pallet is not received in any one recess 235 time, in fixing formation 239, elasticity can be bent away from shell 111.Pallet 159 and teat 245, and the neighbouring part of the bottom of the recess 235 formed by teat is adjusted and is made fixing formation 239,241 apply to be easy to stop motion bar 225 to move apart the power of described position during in the close position and latched position at it each other.The adjacent bottom part of pallet 159, teat 245 and recess 235 is also adjusted makes fixing formation 239,241 apply each other to be easy to stop motion bar 225 time in an open position, move apart the power of described position.

Especially, in the embodiment shown in the drawing, promote to be formed the neighboring edge of recess 235 by elastic restoring force in the flexion bar 225 of the inclined surface against pallet 159 and form the inclined surface of side of teat 245, being easy to be received in towards wherein pallet 159 power moving motion bar closer to the position of any one in recess 235a or 235b aimed at pallet to produce.As illustrated in figure 10, such as, fixing formation 239,241 be constructed such that bottom pallet 159 and teat 245/ recess 235b between interaction produces and to be easy to motion bar 225 with motion bar at ring 113 period of contact close to closed and latched position towards closing and the power F1 of latched position movement.Also through motion bar 225, power F1 is transferred to actuator 115, it is easy to actuator to rotate towards its closing position.

As illustrated in fig. 11, once pallet 159 is received in recess 235b, the interaction between bottom pallet 159 and teat 245/ recess 235b just helps motion bar to be retained on latched position.When motion bar 225 is in latched position, actuator 115 maintains slight tension by the interaction between fixing formation 239,241.This can help the effect reducing or exempt actuator 115 when ring closes.Such as, in fig. 11, when ring 113 closes, pallet 159 is positioned as maintaining to contact with teat 245 making fixing formation 239,241 can produce tension force in motion bar 225.Or recess 235b can make there is not the tension force produced by fixing formation when ring closes relative to pallet 159 sizing and/or location.Such as, in category of the present invention, when ring 113 closes, small―gap suture may be there is between pallet 159 and teat 245.But even if when ring 113 closes, there is not tension force in motion bar 225, after motion bar moves apart latched position, fixing formation 239,241 still produces and is easy to stop motion bar to move apart the power of latched position further.The power stoping motion bar 225 to move apart latched position also stops actuator 115 to move towards its open position and in the actuator closed/latched position that makes actuator and motion bar return when (such as, unexpected) moves apart closing position a little.

With reference to figure 9, when ring 113 is opened, pallet 159 is received in another recess 235a of fixing formation 239.As diagram, fixing formation on motion bar 225 and shell 111 239,241 interact with each other to help motion bar, actuator 115 and ring to be retained on open position.

In addition, fixing formation 239,241 is suitably adapted to provide the user feeding back to manipulation actuator 115, and instruction user actuator 115 and motion bar have completed the movement moving to moving of open position from closing position and/or complete from open position to closing position.Feedback can be the form being moved beyond the relevant sub-audible sound of pallet 159 and/or sense of touch to teat 245.The buckle sound occurred when sub-audible sound can be in pallet 159 is clipped to one of recess.Similarly, when fixing formation 239,241 is configured to slide past pallet 159 during teat 245 is to move between open position and closing position, make the direction of the power being applied to motion bar reverse, its formation can by the sense of touch of user's perception of manipulation actuator 115.In addition, when pallet 159 is received in one of recess 235, the amount being applied to the power on motion bar 225 because of the interaction between fixing formation 239,241 perceivable declines.Although expection may need sense of touch and/or audio feedback, should be appreciated that feedback and the non-key and fixing formation not producing any sense of touch or audio feedback in category of the present invention.

As diagram, whole motion bar 225(comprises locking member 221, sticking department 223, projection 237, recess 235, teat 245, hinge 229 and connecting portion 227) be suitably integrally formed as the single single-piece of plastic polymeric material.But should be appreciated that, in category of the present invention, the different assemblies of motion bar can make separately and assemble to form non-single motion bar.

The operation of ring mechanism 101 is described with reference to Fig. 9 to Figure 11.In fig. 11, ring mechanism 101 is in closed and latched position.Flap 127 downwards hingedly makes that the collar member 133 of each ring 113 is in continuously together away from shell 111, in closed loop, it can fix loose-leaf.The handle 211 of actuator 115 vertical relative to shell 111 essence (when directed as shown in Figure 11) and the openend 121 of latch housing.The locking member 221 of motion bar 225 to be positioned at above flap 127 and its opening 129 but do not aim at opening 129 separately contiguous.The flat bottom surface 271 of locking member 221 adjoins the upper surface of flap 127.The backward extension 275 of locking member 221 extend through adjacent hinge plate 127 forward, under turn each respective opening 129 of tab 281.Each pallet 159 of the fixing formation 241 on shell 111 is received in the corresponding second recess 235b of the corresponding fixing formation on motion bar 225.

Any one occurrence (such as when ring mechanism drops, being surprisingly applied to the power of ring 113 or actuator 115) being easy to motion bar 225 to shift out its latched position produces the interaction fixed between formation 239,241, and it stops motion bar to move apart latched position.In the embodiment shown in the drawing, pallet 159 and teat 245 is interact with each other motion bar 225 is pushed away actuator 115 to produce and sees Figure 10 towards the power F1(that its latched position returns).

In order to ring mechanism 101 be unlocked and open ring 113, user's revolving actuator 115 makes handle 211 rotate away from the platform 117 of shell, and cross bar 233 and motion bar 225 are pulled away from latched position (Fig. 9) towards non-locked position by it.Although locking system 221,225 is moved to non-locked position by actuator 115, by locking member 221 being engaged with the upper surface of flap and stoping the upwards pivotable of center hinge 145 upper flap 127 to move.The pivotable that flap 127 is out of shape to postpone flap on the end of its adjacent actuator 115 moves until locking member 221 moves to aims at the opening 129 in flap.

When moving motion bar 225 by closure arm 203, pallet 159 engagement projection 245 and produce power F1(Figure 10), described power F1 stops the further movement of motion bar and transfers to actuator 115 through motion bar and stop actuator to continue towards open position to rotate thus.User can continue revolving actuator 115 and overcome the resistance that fixing formation 239,241 provides.When motion bar 225 continue further away from each other latched position time, the tip 247 of teat 245 is close to align with pallet 159 and the platform 117 that motion bar is bent away from shell near fixing formation 239 slides past pallet 159 to allow teat.Once align with pallet 159 in the tip 247 of teat 245, fixing formation 239,241 just no longer produces any power stoping motion bar 225 to move apart its latched position.

When locking system 221,225 no longer stops that the pivotable of flap 127 moves, user continues revolving actuator 115 and opening arms 205 is rotated and push away in the center hinge 145 of flap 127 until flap is in co-planar locations (not shown).After the tip 247 of teat 245 has been moved beyond pallet 159, flap 127 has suitably arrived co-planar locations, but this is not necessary.Once flap 127 is moved beyond its co-planar locations, the direction of shell spring force just due to the switching action of flap when it moves through co-planar locations oppositely.Subsequently, flap is moved to its open position by shell 111 and/or actuator 115.Similarly, once the tip 247 of teat 245 slides past the pallet 159 on shell, the direction of the power produced by the interaction of fixing formation 239,241 is just reverse and when pallet is received in recess 235a, pallet promotes motion bar 225 towards actuator 115.This allows the elastic restoring force in motion bar to make motion bar be back to less curved configuration.

When the upwards pivotable of flap 127 has moved and pallet 159 is received in recess 235a, ring 113 (as shown in Figure 9) in an open position.Although ring 113 remains on open position, the interaction between fixing formation 239,241 helps motion bar 225 and actuator 115 to be retained on open position.This can help the effect of limiting actuator 115 when ring is opened.

In order to close and lock ring 113, user simply directly can hold one or more collar member 133 and collar member is moved to closing position from open position.This action of user will cause the center hinge 145 of flap downward pivotable and rotating actuator 115 to closing position by pushing away in opening arms about 205 in shell 111.After flap 127 is opened by pivotable, motion bar and locking member 221 are pushed into latched position by actuator 115.Fixing formation 239,241 suitably stops ring towards the initial movable of closing position due to the interaction between teat 245 and pallet 159.Similarly, shell spring force also stops collar member towards the initial movable of closing position until when flap 127 is through its co-planar locations, the direction of shell spring force is reverse.When motion bar is pushed to latched position (Figure 10), teat 245 slides across pallet 159 and motion bar is bent away from platform 117 until align with pallet in the tip 247 of teat.When flap arrives co-planar locations, the tip 247 of teat is suitably moved beyond pallet 159, but this is not necessary.Once most advanced and sophisticated 247 slide past pallet 159, the direction of the power that fixing formation 239,241 produces just oppositely.Especially, fixing formation 239,241 respectively produces and promotes motion bar 225 to continue towards power F1(Figure 10 of latched position movement).When motion bar 225 arrives its latched position, pallet is received in the second recess 235b.When pallet 159 is clipped in the second recess 235b, produces feedback (such as, sub-audible sound, sense of touch) and feed back to user to provide, help confirms to have closed and ring 113 locks.

User also have use actuator 115 with closed and lock ring 113 and non-manual shift(ing) ring circle component 133 with the selection of closed ring.In order to use actuator 115 to close ring 113, user is relative to revolving actuator on the rightabout of opening sequence.Such as, actuator 115 can be rotated (counterclockwise as shown in Figure 10) to be moved by the platform 117 of handle 211 towards shell 111.When actuator 115 starts towards the rotation of its closing position, closure arm 203 pushes away in the center hinge about 145 of flap 127 and starts flap and moves towards the pivotable of closing position.When user continues actuator 115 to rotate towards closing position, motion bar 225 and the locking member 221 on it promote towards latched position by actuator.If when the closed mobile beginning of actuator 115, the forward edge 273 of locking member 221 is not yet located in against flap 127 on the edge of respective opening 129, and it is so located in by the initial rotation of actuator.

Once locking member 221 is located in (as illustrated in figure 10) against flap 127, flap restriction locking system 221,225 is towards latched position movement further.The continuation of actuator 115 rotates and causes actuator body 201 and contact surface 251 cross bar 233 to be pushed away the openend 121 of shell 111.The power that actuator 115 is applied to cross bar 233 is transferred to locking member 221 through motion bar and makes its inclination forward edge 273 promote to increase the power of flap towards closing position pivotable against tab 281.Meanwhile, closure arm 203 continues to push away at flap about 127 to make closure arm and locking member 221 jointly drive the pivotable of flap to move.

Once flap 127 is through co-planar locations, gained switching action makes the direction of shell spring force oppositely and flap continues to continue to move towards closing position pivotable under the impact of shell spring force, actuator 115 and/or locking member 221 applied force.Abundant after closing position pivotable at flap 127, locking system 221,225 is pushed to latched position and moves to allow this by revolving actuator 115.When motion bar 225 is pushed to latched position, teat 245 slides across pallet 159 and motion bar is bent away from platform 117 until align with pallet in the tip 247 of teat.Initial phase mutual effect between fixing formation 239,241 produces the power being easy to stop motion bar towards latched position movement.Once the tip 247 of teat 245 has slid past pallet 159, the direction of the power produced by fixing formation 239,241 oppositely and power F1(Figure 10) promote motion bar 225 to continue to move towards latched position.When motion bar 225 is close to its latched position, pallet 159 is received in recess 235b.When pallet 159 is clipped in the second recess 235b, produce feedback (such as, sub-audible sound, sense of touch) with provide closed move and the confirmation of ring 113 locking to user.Now, motion bar 225 and the locking member on it 221 are retained on latched position by fixing formation 239,241 again releasedly.
