Abstract
A ring binder mechanism that retains loose-leaf pages and has ring members that are easy to open and close and that readily lock together when closed. The mechanism comprises a housing that supports two hinge plates for loose pivoting motion. The hinge plate motion moves the ring members between an open position for loading pages and a closed position for retaining pages. The mechanism also includes a control structure that can pivot relative to the housing to controllably move the hinge plates to bring the ring members together. The control structure is releasably held behind protrusions of the hinge plates, thereby blocking the hinge plates pivoting motion and positively locking the ring members together.

The mutual reference of related application
It is the right of the U.S. Provisional Application of No 60/553154 that the application requires the series number of 15 applications March in 2004, and content wherein is incorporated herein by reference.
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 improved be used to reduce described annular element when closed unexpected engaging and make described annular element close and be locked together in mechanism together reliably.The invention still further relates to a kind of annular element of filling the loose-leaf paper that makes and be easy to the mechanism of opening and closing.
Background technology
In the prior art, a kind of circular ring loose-leaf binder mechanism of standard will be fixed in 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.When described articulated slab was in the position (180 °) of a coplane, described housing 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 a tensile-elasticity 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 circular ring loose-leaf binder mechanism 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 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 circular ring loose-leaf binder mechanisms 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.Barrettl, the patent No. of Jr is 4566817, the patent No. of Vogl be 4571108 and the patent No. of Snyder or the like be that the patent No. of 6276862 United States Patent (USP) and Kokuyo company is 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.
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, 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.For these reasons, large-scale production will cause the increase of cost
The circular ring loose-leaf binder mechanism of other types is also attempted to overcome the unexpected engaging of described annular element and is made described annular element be locked together in together reliably.For example, some mechanisms are arranged on the described articulated slab, and when it makes pivoting action never by described co-planar locations (180 °).Because avoided the described co-planar locations (180 °) of described articulated slab, therefore, described annular element can not be fastened togather when closing suddenly.But, act on the described annular element closing force comparatively speaking a little less than, therefore must provide one independently locking system so that described annular element keeps closing state.The application people is the No5660490 United States Patent (USP) of Warrington and applies for that the people has disclosed such circular ring loose-leaf binder mechanism for the No952536 BP of Bennett.Some other arrangement of mechanism is on articulated slab and housing, so that described articulated slab can only be by faint bias voltage to described housing.Independent line spring combines with the bottom of described articulated slab to provide one to make described articulated slab be switched to the biasing force of the position that described annular element opens.The application people is the circular ring loose-leaf binder mechanism that the U.S. Patent application of No2003/0123923 has disclosed this type for the publication number of Koike or the like.
The application people be in the described mechanism of patent of Warrington and Koike or the like, and the end of described annular element forms crook, described crook when described annular element is closed combination so that described annular element remains on described closed position.Make described crook in conjunction with also separating in order to control described annular element, it needs certain proficiency.If be full of the loose-leaf paper between the described annular element, then handle and become more difficult.In addition, described crook is to causing the unexpected power of opening of described circular loose-leaf binder more responsive.Moreover, have a plurality of circular loose-leaf binders, need described crook simultaneously in conjunction with or the circular ring loose-leaf binder mechanism that separates might make handle more loaded down with trivial details and difficult.
The application people is that described drive rod links to each other with the end of described housing in the described mechanism of patent of Bennett.The angle of one end of described bar bending is slightly larger than the right angle, so it can directly make described articulated slab pivot closing described annular element and pivoting action that further can the described articulated slab of locking, and makes described annular element keep together.But this can't sealedly reliably be in the described annular element of closure state.If described mechanism plunks down or described housing owing to reusing when being out of shape, the described bar described lock position of might slipping away.
Therefore, the purpose of this invention is to provide a kind of circular ring loose-leaf binder mechanism, described mechanism can be reliably and effectively described annular element is locked at together with fixing described loose-leaf paper, simultaneously when being full of paper in the described annular element, the opening and closing at an easy rate of described annular element, and described annular element can not be fastened togather when closure suddenly.The present invention promptly relates to described this circular ring loose-leaf binder mechanism.

The specific embodiment
The application's theme and the name of application simultaneously are called soft close ring binder mechanism and name to be called the theme of circular ring loose-leaf binder mechanism of dual pivot locking elements all identical, and content wherein is incorporated herein by reference.
Referring to accompanying drawing of the present invention, accompanying drawing 1 shows the described circular ring loose-leaf binder mechanism according to the first embodiment of the present invention, and described mechanism is by Reference numeral 1 expression.Described mechanism can clamping loose-leaf paper (not shown) and is installed in the drawings on the ridge 3 of notebook, 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.Described mechanism 1 generally includes 11, three annulus 13 of a housing and a control structure 15 (described its theme of Reference numeral ordinary representation).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.Shown in accompanying drawing 2A-3B, described housing 11 supports described control structure 15 and described ring 13.As will be described below, described control structure 15 can move to close and sealed described mechanism 1 and the described loose-leaf paper of clamping or open described mechanism with to described ring 13 increase and decrease paper with respect to described housing.
The flat-top 17 of the rising of described housing comprises five openings.Wherein two openings 29,31 are circular, are used to receive and connect the installation column 33,35 that described mechanism 1 can be fixed on the notebook 5.Other three openings 37,39,41 are rectangle, are respectively applied for the part of first, second and the 3rd locking element 43,45,47 that receive described control structure.Described each rectangular aperture 37,39,41 comprises two juts that protrude upward 49.Described every pair of jut receives a swivel pin 51, and described swivel pin passes the upper opening 53 that is positioned on the corresponding locking element 43,45,47 and links to each other so that described locking element is pivoted with described housing 11.When described controlling organization 15 moves and when making that described mechanism 1 opens, described each stop 55 is pressed and is received the part of the convex 57 of described each locking element 43,45,47 on slightly by the flat top portion 17 of described rising.Should understand that difform housing is as the housing of asymmetric shape and have varying number and claimed scope that the housing of the opening of shape or slit does not break away from the present invention equally.
Referring to accompanying drawing 2A, 3A and 4, described each ring 13 comprises two annular elements 63 that are installed on one of described two articulated slabs 59,61.Described two articulated slabs 59,61 are subjected to the support of described housing 11 to move pivotally, and described annular element 63 moves between closed position and open position simultaneously.It is circular that the cross section of described annular element 63 is similarly, and formed by the metal manufacturing that is fit to such as steel or the like.In described closed position, described annular element 63 has formed " D " type annulus of a continuously basic and sealing or loop (referring to accompanying drawing 2B) with the described loose-leaf paper of clamping and allow described these paper to move to another annular element along described ring 13 by an annular element 63.And when it was shown in an open position, described each annular element had formed a discontinuous open loop (referring to accompanying drawing 3B) that is suitable for increasing and decreasing paper.Although described in an illustrated embodiment two annular elements can move, 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 break away from the present invention's scope required for protection yet.
Described each articulated slab 59,61 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 59,61 has two otch and two protrusion members, and wherein said otch is positioned at longitudinal end, and two protrusion members are therebetween simultaneously.When described articulated slab 59,61 links to each other, corresponding otch of described each articulated slab and protrusion member alignment.Shown in accompanying drawing 5A, described otch is formed with two openings 67,69 so that described installation column 33,35 passes the articulated slab 59,61 that interconnects.As what further illustrated in the accompanying drawing, described protrusion member is in line and forms two juts 65,66, described jut is symmetrically located on the center hinge of the described articulated slab that interconnects 59,61 so that described control structure 15 releasably is supported on a lock position, stops described articulated slab 59,61 to pivot and makes described annular element 63 open (referring to accompanying drawing 5B).
Referring to accompanying drawing 2B, 3B, 5A and 6A, described interconnective articulated slab 59,61 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 articulated slab 59,61 that links to each other, thereby makes the outside longitudinal cut limit pine loose ground of described each plate be positioned at the rear (referring to accompanying drawing 2B and 3B) of the corresponding curved bottom frame 19 of described housing.In this structural configuration, described articulated slab 59,61 is fixed on the described housing 11, but described cutting shoulder can move in described frame 19 backs, thereby makes described plate 59,61 to pivot arbitrarily around described pivotal axis.When described articulated slab 59,61 pivots and when opening described ring 13, move (promptly the flat-top 17 towards the rising of described housing moves) on the described pivotal axis, and pivot when closing described ring 13 when described plate 59,61, described pivotal axis moves down the flat-top 17 of the rising of described housing (promptly away from).
In addition, described articulated slab 59,61 is designed to pivot in described housing 11, therefore the included angle A between the described outer surface of the described articulated slab flat-top 17 of the rising of described housing (promptly away from) is always less than 180 °, and described pivotal axis moves to a co-planar locations being lower than described plate 59,61 (being that included angle A between the described outer surface of described articulated slab 59,61 is 180 ° position) never.Therefore, the elastic force of described housing 11 makes described articulated slab 59,61 pivot so that described annular element 63 is opened, and can not close.But should understand that in certain embodiments, the angle between the described outer surface of described articulated slab can be greater than 180 °, so, the elastic force of housing can be so that described articulated slab pivots towards the closed position.In addition, the present invention's certain embodiments can be designed to described articulated slab to pivot up and down and co-planar locations (180 °) by described articulated slab.
As noted earlier, described housing 11 support and control structures 15 move with respect to described housing 11 making it.Again referring to accompanying drawing 4, the control structure 15 of present embodiment comprises described drive rod 27, motion bar 71 and three locking elements 43,45,47.Described drive rod 27 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 73 that enlarges is so that firmly grasp described bar 27 and apply power to it.As mentioned above, described first swivel pin 25 passes the upper opening 75 of described drive rod and the jut 23 of described housing 11, and described bar 27 is installed on the described housing 11 to make it with respect to described housing 11 pivots.One second swivel pin 79 passes the lower openings 81 of described drive rod and the described opening 83 of an intermediate connector 85, thereby the pivoting action of described bar is converted to the linear movement of described motion bar.
In the present embodiment, described intermediate connector 85 is generally and has a flat web and the slender beam of two side flanges.Have an elongated opening on its web and pass one of them installation column 33, allow described connector 85 to move with respect to described installation column 33 in order to reception.It has a width first end slightly wide than second end simultaneously.More particularly, the second narrower end of described intermediate connector 85 has a protuberance 93, and described protuberance has an end 95 that enlarges, and described end is arranged in a slit 97 of first end of described motion bar.Described first end of described motion bar is bent downwardly simultaneously and forms an end flange 99, and described flange 99 can prevent that described intermediate connector 85 is pushed to described motion bar 71.The end 95 of the described expansion of described protuberance 93 can combine with the rear portion of described end flange 99, thereby allows described intermediate connector 85 to push described motion bar 71 to described drive rod 27.Be used to admit the slit 97 of the described motion bar of described protuberance 93 to be slim-lined construction along the length direction of described motion bar 27.Therefore, described intermediate connector 85 can pivot up and down arbitrarily with respect to described motion bar 71.So described intermediate connector 85 can transfer to described motion bar 71 by the drive rod 27 of described pivot with a linear movement.In addition, described motion bar 71 can move up and down and can not interfere described intermediate connector 85.Although the motion of described motion bar not exclusively is linear, consider that by purpose of the present invention described this motion should be regarded as linear.
Described motion bar 71 is parallel to the longitudinal axis of described housing usually and places (accompanying drawing 5A and 6A) in described mechanism 1, and is positioned at flat-top 17 belows of the rising of described housing, the top of described articulated slab 59,61.In the present embodiment, as mentioned above, described motion bar 71 is for having the slender beam of a flat web, two side flanges and end flange 99.Described web has two rectangular apertures 105,107 that are used to receive by first and second locking element 43,45 of described motion bar 71 between the end of described motion bar.Described each opening 105,107 comprises two lug bosses 109 that protruded upward by the described side flange of described motion bar.Described each lug boss 104 is received the hole passed on the described lug boss and a swivel pin 111 of a lower openings 113 on the corresponding locking element 43,45, make described locking element 43,45 pivot and link to each other with described motion bar 71.Second end of described motion bar 71 is open shape, does not have end flange and web part also to be removed.At this end, the lug boss 109 of described two lug bosses 100 and described rectangular aperture is the same to protrude upward and receives the swivel pin 111 that passes a lower openings 113 on described the 3rd locking element 47 by described side flange, makes described locking element 47 pivot with described motion bar 71 and links to each other.
Referring to accompanying drawing 4-6B, when being seen by the front of described mechanism or back, described three locking elements 43,45,47 are rectangular, when being seen by the side are described locking element wedgewise.Described each locking element 43,45,47 comprises the top of a circle, a front surface, a rear surface, the bottom of a circle and two straight parallel side portions.As mentioned above, described side surface has top and lower openings 53,113 so that the linking to each other of described locking element and described housing and described motion bar.The top of described circle protrudes upward and passes corresponding rectangular aperture 37,39,41 on the flat-top 17 of described housing rising.Described front and rear surfaces and described rounded bottom are angled, have formed the convex 57 of described locking element.Described convex 57 passes second end that is open shape of corresponding rectangular aperture 105,107 and described motion bar.Correspondingly, in the present embodiment, the linear movement of described motion bar makes described locking element 43,45,47 state commentaries on classics, and and then (1) make described articulated slab 59,61 pivot with the pivoting action of closing described annular element 63 and stoping described articulated slab 59,61 with the sealed described annular element of closing 63, perhaps (2) allow the elastic force of described housing to make described articulated slab 59,61 pivot to open described annular element 63.Should be contemplated to, described each locking element of present embodiment is formed by plastics or hard rubber manufacturing, but adopts other rigidity to be enough to make described articulated slab to pivot and stop the material of described hinge plate motion also to be fine.Should understand that the number of the locking element of described control structure is greater or less than three, or the claimed scope that adopts the locking element of other shapes not break away from the present invention equally.
Accompanying drawing 2A-3B and 5A-6B show the operating process of described mechanism.Described control structure can optionally make described mechanism 1 move to and close and latched position (accompanying drawing 2A, 2B, 5A and 6B) and open position (accompanying drawing 3A, 3B, 6A and 6B).Close and latched position described, described annular element 63 combines and can not be pulled away from.The orientation of described articulated slab 59,61 makes the included angle A between its outer surface reach maximum, but still less than 180 ° (being the top that the described pivot axis of described articulated slab is positioned at described co-planar locations (180 °)).In addition, described drive rod 27 is vertical configuration, and simultaneously described motion bar 71 is near housing one end that comprises bar 27.The longitudinal axis approximate vertical of described each locking element, the convex of described each locking element combines with the rear of described articulated slab 59,61 at corresponding lug boss 65,66 simultaneously, and stoping described articulated slab 59,61 to be stated changes and the sealed reliably annular element 63 that is in closed condition.In described this position, because the size of described locking element makes it to occupy fully the zone between described articulated slab 59,61 and the described housing 11, therefore described locking element 43,45,47 has firmly stoped any power that is intended to open described annular element 63.Therefore, when described articulated slab 59,61 upwards promotes described locking element 43,45,47 (when described articulated slab 59,61 pivot and when making that described annular element 63 is opened), described articulated slab 59,61 combines with described locking element 43,45,47 immediately and has and makes described locking element and motion bar 71 uptrends.Yet described housing 11 stops this motion (by passing the described swivel pin 51 of described lug boss 49), and stops described annular element 63 to be opened together with described locking element 43,45,47.
In order to open described mechanism 1, the also downward described drive rod 27 (accompanying drawing 3A and 6A) that pivots of user's (not shown) downwards.This away from an end of the described housing with bar 27, and makes described locking element 43,45,47 pivot with regard to making described intermediate connector 85 and motion bar 71 be promoted.Described first and the convex 57 of the 3rd locking element begin to be positioned at the top of the respective bump portion 65,66 of described articulated slab, force described articulated slab 59,61 slightly to move down.When described convex 57 moved through corresponding lug boss 65,66, it allowed the elastic force of described housing to make described articulated slab 59,61 upwards pivot.Described convex 57 continues to move and enters in the stop 55 of described housing until its part, thereby allows described articulated slab 59,61 upwards to pivot completely and open described annular element 63.At described open position, described locking element 43,45,47 no longer stops the pivoting action of described articulated slab, and the included angle A between the described outer surface of described articulated slab reaches minimum.The elastic force of described housing makes described annular element 63 stay open, and described user can let go described drive rod 27 and increase and decrease paper to described mechanism 1 simultaneously.
In order to make described mechanism 1 be back to described closing and latched position, inside and described drive rod 27 (the accompanying drawing 2A that upwards pivots of user, 5A), on the contrary described intermediate connector 85 and described motion bar 71 are pulled back to the shell ends with described bar 27 mutually with described unlatching effect.This just makes described locking element 43,45,47 pivot and makes its convex 57 shift out described stop 55.Along with the pivot of locking element 43,45,47, described convex 57 makes described articulated slab 59,61 move down at leisure and overcomes the elastic force of described housing, thereby gently makes described annular element 63 closures.Described convex 57 is moved by corresponding lug boss 65,66, and simultaneously described locking element 43,47 is in one and makes the annular element 63 of described closure be locked together in position together reliably.In fact, when described locking element 43,47 moved to described lock position on the corresponding lug boss 65,66, the user can hear the sound of " Ka Ta ", describedly so sealedly can be confirmed.The described locking element 43,45,47 that it is pointed out that described mechanism makes described articulated slab 59,61 pivot just in order to close and sealed described annular element.It can not make described articulated slab 59,61 pivot to open described annular element 63.Described these elastic force by housing are finished.
As mentioned above, a beneficial effect of described mechanism is that described locking element 43,45,47 occupies the zone between described articulated slab 59,61 and the described housing 11 usually fully.In addition, described locking element 43,47 is positioned at the rear of the corresponding lug boss 65,66 of described articulated slab reliably, and is surrounded by described housing 11, thereby stops described mechanism 1 to open unexpectedly.Based on two reasons, when described annular element 63 was closed, described mechanism 1 made described loose-leaf paper be able to clamping reliably.
Described mechanism 1 can also reduce undesirable unexpected engaging when described annular element is closed.When the user pivoted described drive rod 27 and makes that described annular element 63 is closed, described locking element 43,45,47 made described articulated slab 59,61 at leisure and moving down of being controlled, thereby gently closes described annular element 63.In addition, 1 existing mechanism of described mechanism is easier to open.Automatically make described articulated slab 59,61 pivot and before opening described annular element 63, the user only need make described motion bar 71 move short distance so that described locking element 43,45,47 pivots and makes described convex 57 be moved by the corresponding lug boss 65,66 of described articulated slab at the elastic force of described housing.Similarly, because the mechanical property that described bar 27 is had, the pivoting action of described drive rod has reduced makes described motion bar move required power.In addition, when paper was expired in described annular element 63 fillings, opening and closing of described mechanism 1 was more easy.With the described annular element of direct control to open and to open described annular element and compare, in this mechanism, the user can pivot described drive rod 27 to open described mechanism 1 and to make described annular element 63 open.
Accompanying drawing 7-10B shows one second embodiment of the present invention with Reference numeral 201 expressions.In the described mechanism of second embodiment with the described mechanism of described first embodiment in corresponding parts represent prefix " 200 " in addition just with identical Reference numeral.Present embodiment and described first embodiment are similar, but as shown in Figure 7, it comprises two line springs 323, and described line spring links to each other with the bottom of described two articulated slabs 259,261, in order to promote described articulated slab 259,261 pivots and to open described annular element 263.In order to place described spring 323, described each articulated slab 259,261 comprises two notches 325 and otch 327 that is provided with along longitudinal cut limit outside the described plate.Described notch 325 is arranged side by side and has formed betwixt a lug boss 329.Described lug boss 329 is towards one of described each articulated slab longitudinal end, and described otch 327 is towards another longitudinal end of described each articulated slab simultaneously.On described two articulated slabs 59,61, described otch 327 and described lug boss 323 are with opposite being disposed in order, therefore when described articulated slab 259,261 when described inner longitudinal cut limit interconnects, the otch 327 of a described articulated slab is passed by the lug boss 329 of described another articulated slab.
Accompanying drawing 8A-8C is the zoomed-in view of described Hookean spring 323.Described spring 323 metal wire manufacturings by a circle own form, and it forms the octagon (described open end forms one of described octagon side) with an open end and a closing end 323a.Described closing end 32 upwards bends 90 °, thereby matches with described notch 325 and lug boss 329 on one of described articulated slab that interconnects 217,219.This is positioned at the rear of the bottom frame 219 of one of housing bending with regard to the free end that allows described lug boss, and the closing end 323a of described spring can be positioned on the described jut 329 simultaneously.The openend of described each 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 327 of described relative interconnective articulated slab separably.When described line spring 323 links to each other with described two articulated slabs, described spring be the below that in fact arc main part be positioned at the described articulated slab that interconnects 259,261 (main part of described spring slightly upwards is interconnected to the articulated slab bending towards described).
Referring to accompanying drawing 9A-10B, when described articulated slab 259,261 was in the position that described annular element 263 opens, when connecting, described line spring 323 was comparatively lax.The arc main part that is of described spring makes described articulated slab be in included angle A between its outer surface less than 180 ° of positions (being the top that the pivot axis of described articulated slab is positioned at described articulated slab 259,261 co-planar locations (180 °)).Close and during sealed position (referring to accompanying drawing 7,10A and 10B) when described mechanism 201 moves to one, the deflection of described each line spring 323 appropriateness is so that describedly be arc part and flatten, thereby makes described spring 323 pressurizeds.When described mechanism 201 moves back to described open position (accompanying drawing 9A and 9B), the spring of described pressurized 323 restore to the original state and automatically make described articulated slab 259,261 upwards pivot and by described co-planar locations (180 °) to open described annular element 263.
In the present embodiment, described line spring 323 makes described articulated slab 259,261 pivot to open described annular element 263.As mentioned above, because described lax spring 323 stops described articulated slab to be intended to the motion that makes described spring 323 deflections and close described ring-type element 263, so it makes the described annular element of opening 263 keep the state that separates.Therefore, described line spring 323 has been realized the effect identical with the elastic force of described housing.Thereby the elastic force that a beneficial effect of described mechanism 201 is described housings can reduce or eliminate, and only stays described line spring 323 to apply effect to described articulated slab 259,261.This just make described articulated slab 259,261 downward move and more easy by co-planar locations (180 °), thereby make described mechanism 201 be easy to close.
