Description

Be used to keep the ring mechanism of loose leaf paper

Technical field

The utility model relates to a kind of circular clip mechanism that is used to keep loose leaf paper, relates in particular to a kind ofly to be used for the open and close ring component and to be used for the improved circular clip mechanism that the ring component with closure locks together.

Background technology

To for example the punch loose leaf paper of paper of circular clip mechanism remains in file or the notebook.It has the ring component that is used to keep paper.Ring component can optionally be opened to add or to take out loose leaf paper, and is perhaps closed to keep loose leaf paper that loose leaf paper is moved along ring component.Ring component is installed on two adjacent articulated slabs that pivot axis links together.Thin-long casing is supported on articulated slab in the housing and with articulated slab loosely and keeps together, and makes their housing pivots relatively.

When articulated slab was in co-planar locations (180 °), undeformed housing was slightly narrower than the articulated slab that connects.Like this, when articulated slab pivoted through this position, they made the elastic shell distortion and produce elastic force in housings, forced the articulated slab pivot and left this co-planar locations, opened ring component or closed hoop parts.Therefore, when ring component was closed, elastic force was resisted hinge plate motion, and ring component is clipped together.Similarly, when ring component was opened, elastic force kept separately them.The operator can overcome this power by manually drawing back ring component or they being pushed away together usually.Can be provided with control handle in the housing one or both ends, be used for shift(ing) ring parts between open position and closing position.But the shortcoming of the circular clip mechanism that these are known is that when ring component was closed, they were not to lock together reliably.If when therefore this mechanism's accident dropped, ring component may by mistake be opened.

Some circular clip mechanisms have been modified to comprise locking mechanism, thereby when ring component is closed, stop that articulated slab pivots.This locking mechanism locks together the ring component of closure reliably, prevents that when the ring mechanism accident drops ring component from by mistake opening.Locking mechanism also makes housing elastic force reduce, because do not need strong elastic force that the ring component of closure is clipped together.Therefore, the required operator's active force of the ring component of these mechanisms of open and close is less than traditional ring mechanism.

In these ring mechanisms some are attached to locking mechanism on the control slide block that is connected with control handle.Control handle moves control slide block (and locking mechanism), so that or stop the pivot of articulated slab or allow its rotation.But, the shortcoming of these mechanisms be the operator must be after with the ring component closure mobile reliably control handle, make locking mechanism be positioned to stop articulated slab and pin closed ring component.Do not carry out this process and articulated slab will unexpectedly be pivoted and open ring component, particularly when mechanism's accident drops.

Some locking circular clip mechanisms use spring locking mechanism to be moved to the position that stops articulated slab when ring component is closed.These examples can be referring to U.S. Patent application 10/870801 (Cheng etc.), 10/905606 (Cheng) and 11/027550 (Cheng).These mechanisms use independent spring to come retaining ring mechanism.

The motion of locking mechanism normally linear or translation, drive but this motion is a pivot by control handle.Therefore, only need the translational component of the motion of control handle is passed to locking mechanism.Multiple solution has been proposed.For example, referring to total U.S. Patent application No.10/870801.Yet, need be cheap, overall structure simple and the reliable structure of repetitive operation realizes the transmission of moving with making.

slab

127a, 127b, and is positioned to make their interior longitudinal edge roughly to align with the interior longitudinal edge of articulated slab.The purposes of otch 129a-d and fingers 131 will illustrate below.Control handle 115 and articulated

slab

127a, 127b broadly are called " actuating system ".

Referring to Fig. 2 and 3, control handle 115 comprises handle 133, be contained in the main body 135 on the handle and be contained in upper lip 136 and lower lips 137 on the main body.Handle 133 is convenient to grasping control handle 115 and applies active force move control handle than each wide slightly (Fig. 2) in main body 135, upper lip 136 and the lower lips 137.In illustrated ring mechanism 101, main body 135 forms as one with handle 133, so that move with handle basically.Main body 135 can form dividually and adorn thereon with handle 133, and this does not break away from scope of the present utility model yet.

Shown in Fig. 3 and 6, the lower lips 137 of control handle 115 is installed on the main body 135 by the flexible bridge portion 139 (or " hinges ") that forms as one with main body and lower lips.The bridge portion of control handle and main body and/or lower lips are separated and are formed and the ring mechanism that main body and lower lips link together is not broken away from scope of the present utility model yet.Bridge portion 139 is arc substantially, and forms open slot 141 between lower lips 137 and main body 135.Lower lips 137 at bridge portion 139 and groove 141 places away from main body 135 extend, with upper lip 136 substantially parallel alignment and formation C shape space between main body 135 and lower lips 137.Can contemplate that control handle 115 is for example made by elastic polymeric material by molding process.But in the utility model scope, control handle 115 can be made by other material or other technology.Have with the ring mechanism that illustrates and illustrate difform control handle here and also do not break away from scope of the present utility model.

Referring to Fig. 3,13 and 14, ring mechanism comprises carriage release lever 145 and the intermediate connector 167 that forms as one with this carriage release lever.Carriage release lever 145 comprises elongated lock portion 148 and isolated three locking elements 149 along the bottom surface of lock portion.More specifically, make each longitudinal end near lock portion 148 have the position that a locking element 149 and locking element are positioned at approach locking part center.Elongated lock portion 148 and locking element 149 can broadly be called " fastening system ".

The locking element 149 of diagram lock portion 148 has substantially the same shape.Shown in Figure 13 and 14, each locking element 149 comprises narrow flat bottoms 153, the leading edge 155a that tilts, recessed sidepiece 155b (only a sidepiece as seen) and extension, rear portion 156.In the illustrated embodiment, locking element 149 has the shape of approximate wedge shape.The sloping edge 155a of locking element 149 can with articulated

slab

127a, 127b engages, and helps articulated slab to pivot downwards.In illustrated embodiment, locking element 149 is for example made one by molding process and carriage release lever 145.But locking element 149 can be made respectively and adorn thereon with carriage release lever 145, and does not break away from scope of the present utility model.In addition, the locking element of difformity for example block (that is, not having sloping edge or recessed sidepiece) is also in the utility model scope.

The intermediate connector 167 of ring mechanism 101 is included in the connector part 168 and the flexible hinge 170 between lock portion 148 and connector part 168 of carriage release lever 145 1 ends.Connector part 168 is formed with elongated opening 168a, is used to hold the erection column 179a that passes this opening, 179b, and in the operating process of mechanism 101, allow carriage release lever 145 with respect to erection column along housing 111 lengthwise movements.Connector part 168 is connected in control handle 115 at upper lip 136 places of control handle by mount pin 171, makes the pivoting action of control handle produce the translational motion of carriage release lever 145.The flexible hinge 170 of carriage release lever 145 approaches, and has " U " shape of general planar when lax.Flexible hinge 170 can deflection or is bent to more obviously " U " shape, and the connector part 168 that makes carriage release lever 145 with respect to and towards locking element 149 motions.

Fig. 2 and 4-7 show the ring component 123a of the ring mechanism 101 that is in closed and locked position, 123b.The locking element 149 of lock portion 148 is positioned near the corresponding otch 129a-d, and at articulated

slab

127a, 127b roughly aligns with hinge 175 top.Locking element 149 does not align with otch 129a-d basically.Flat bottom surface 153 leans against articulated slab 127a, and on the upper surface of 127b, and the preceding curved protuberance 182 down of extension, rear portion 156 next-door neighbour's articulated slabs passes each corresponding otch 129a-d.Lock portion 148 and locking element 149 are resisted together and are tending towards making articulated

slab

127a, and 127b upwards pivots and opens ring component 123a, any active force of 123b (that is the closed ring component of they lockings).

In order to open ring component 123a, 123b, control handle 115 outside and pivot (along the clockwise direction shown in the arrow of Fig. 6) downwards.As shown in Figure 8, lower lips 137 and articulated slab 127a, the bottom surface of 127b engages, and upper lip 136 is towards not lock position pulling carriage release lever 145 and locking element 149.Control handle 115 forms at articulated slab 127a, and 127b pivots and opens ring component 123a, before the 123b locking element 149 is pulled away from locked position.More specifically, before articulated slab pivoted, locking element 149 was moved and at articulated slab 127a, aligns above the respective cut 129a-d of 127b.Flexible hinge 170 can extend under from the pulling force of upper lip 136 slightly, but it keeps its shallow " U " shape substantially to a great extent.139 deflections of flexible bridge portion and tensioning between the lower lips 137 of the main body 135 of control handle 115 and control handle.Open slot 141 closures between main body 135 and lower lips 137, main body moves and engages with lower lips.The continuing of control handle 115 opened motion causative subject 135 lower lips 137 that pivots jointly, upwards promotes articulated slab 127a, and 127b passes through co-planar locations.This is with ring component 123a, and 123b moves to open position, shown in Fig. 9-11.

For closed hoop parts 123a, 123b and make this mechanism 101 return to locked position, operator can make control handle 115 upwards and inwardly pivot.Shown in Figure 12 A, this upper lip 136 with control handle 115 moves to contact articulated slab 127a, the upper surface of 127b (if it does not also contact the upper surface of articulated slab).Upper lip 136 and articulated slab 127a, the upper surface of 127b engages, and begins they are pushed away downwards, but the initial hinge plate motion of the elastic force of housing 111 opposing.Carriage release lever 145 can initially travel forward along with the motion of upper lip 136, makes the leading edge 155a of locking element 149 abut against articulated slab 127a, on the protuberance 182 of 127b (if locking element also not near).Along with control handle 115 continues to pivot, near locking element 149 stop carriage release levers 145 further to move.Shown in Figure 12 A, flexible hinge 170 beginnings crooked (or downward bias changes into more obviously " U " shape) of carriage release lever 145 are so that control handle 115 continues to pivot.The connector part 168 of intermediate connector 167 and this relative motion between the locking element 149 cause and produce tension force in the flexible hinge 170.When closing motion this moment, if control handle 115 is at articulated slab 127a, 127b pivots downwards and is released through (promptly at ring component 123a, before the 123b closure) before their co-planar locations, and the tension force in the flexible hinge 170 will automatically make control handle bounce-back (and pushing away) go back to its starting position.

Shown in Figure 12 B, the continuation closing motion of control handle 115 causes upper lip 136 with interconnective articulated

slab

127a, and 127b pivots downwards.In case articulated

slab

127a, 127b have just passed through co-planar locations, the elastic force of housing just pushes away them downwards, makes ring component 123a, the 123b closure.Along with articulated

slab

127a, 127b pivots downwards, and the inclination leading edge 155a of locking element 149 makes locking element and carriage release lever 145 move (shown in Figure 12 B) to the left.Flexible hinge 170 keeps distortion and tensioning in the process of initial motion.In case articulated

slab

127a, 127b cross the inclination leading edge 155a of locking element 149, they just no longer resist travelling forward of locking element and carriage release lever 145.Locking element 149 moves at articulated slab 127a along with control handle 115 now, their locked position of 127b back.Simultaneously, bridge portion 139 becomes smooth, and the tension force in the flexible hinge 170 makes locking element 149 bounce-backs and further is pushed into locked position.Bridge portion 139 and flexible hinge 170 turn back to their slack position.Mechanism 101 is in position shown in Figure 6 once more.

In this ring mechanism 101, the flexible hinge 170 of intermediate connector 167 allows control handle 115 to pivot, and makes articulated

slab

127a, and 127b moves downward so that locking element 149 is being pushed into closed hoop parts 123a before the locked position of articulated slab back, 123b.It also provides flexibly connecting between connector part 168 and lock portion 148.(through connector part 168) protection lock portion 148 was avoided moving both vertically, and makes locking element 149 keep motionless (vertically) in operating process from slightly the moving both vertically of control handle 115 when flexible hinge 170 received control handles and pivots.

In the embodiment of Fig. 1-16, the flexible hinge 170 of illustrated intermediate connector 167 roughly forms as one with the connector part 168 of lock portion 148 and carriage release lever 145 between lock portion and connector part.Yet shown in Figure 17-19, flexible hinge 170 ' can form independent parts with the connector part 168 ' of the lock portion 148 ' of carriage release lever 145 ' and intermediate connector 167 ' and be connected to above them.Flexible hinge 170 ' is formed with hooked end 170a ', and hooked end is contained in respectively in the opening 150 ', 152 ' on lock portion 148 ' and the connector part 168 '.In scope of the present utility model, flexible hinge 170 ' can be connected in lock portion 148 ' and connector part 168 ' by different way.When operation, the flexible hinge 170 ' of Figure 17-19 is similar to flexible hinge 170 bendings of Fig. 1-16.

It should be understood that flexible hinge can be the shape shown in being different from, also still in scope of the present utility model.For example,, flexible hinge folds, so that regulate the lengthwise movement of connector part with respect to lock portion but can being concertina elasticity.

Can expect that each part of carriage release lever and intermediate connector is made by plastic material, but they can be made by other suitable materials such as metal.In addition, the different piece of carriage release lever can be made from a variety of materials, but should be appreciated that flexible hinge made by spring steel, plastics or other flexible materials.

Figure 20-32 shows the circular clip mechanism 201 of another embodiment.Mechanism 201 is similar to the mechanism 101 shown in front description and Fig. 1-19, but does not comprise U-shaped hinge 170.The parts of the ring mechanism 201 corresponding with the parts of the ring mechanism 101 shown in Fig. 1-16 are represented with the same reference numerals that adds " 100 ".In this embodiment, intermediate connector 267 forms as one with carriage release lever 245, but connects by hinges 272, and this hinges can make intermediate connector pivot with respect to carriage release lever, but the U-shaped flexible hinge 170,170 ' that does not resemble Fig. 1-19 like that longitudinally is out of shape.Therefore, in mechanism 201, hinges 272 converts the pivoting action of control handle 215 translational motion of carriage release lever 245 to, but does not allow control handle 215 to pivot with

closed hoop parts

223a, 223b before carriage release lever 245 and locking element 249 move to locked position.For

closed hoop parts

223a, 223b can manually push away them together.

Shown in Figure 22,31 and 32, the illustrated carriage release lever 245 of this embodiment comprises elongated lock portion 248, and this lock portion has three locking elements 249.Intermediate connector 267 hingedly is connected in lock portion.The shape of the locking element 249 of lock portion 248 is similar to the locking element 149 of foregoing mechanism 101.Intermediate connector 267 is formed with elongated opening 267a, is used to hold the erection column 279a that passes this opening, and carriage release lever 245 is moved with respect to erection column in the operating process of mechanism 201.Shown in Figure 23 and 25, intermediate connector 267 is connected in flat control handle 215 (that is, comparing the control handle with flat grip with the control handle 115 of the mechanism (Fig. 1-19) of front) at upper lip 236 places of control handle.Hook portion 236a on the upper lip 236 of the cross bar 271 controlled handles 215 of intermediate connector 267 catches.

The opening operation of the opening operation of this mechanism 201 is similar to previously described (Fig. 1-19) mechanism 101.Figure 20-25 shows the ring mechanism 201 that is in closed and locked position.In order to open ring component 223a, 223b, control handle 215 outwards and downwards pivot (along shown in arrow among Figure 24 in the counterclockwise direction).As shown in figure 27, lower lips 237 beginning of control handle 215 upwards pushes away on the bottom surface of 227b at articulated slab 227a, and the upper lip 236 of control handle with carriage release lever 245 and locking element 249 be pulled to articulated slab on opening 229a, 229b, the not lock position of 229c alignment.Between the lock portion 248 of carriage release lever 245 and intermediate connector 267 and being articulated and connected between intermediate connector and control handle 215 intermediate connector is slightly upwards pivoted with respect to lock portion, thereby the adjusting control handle slightly moves upward when control handle pivots.239 deflections of flexible bridge portion and tensioning between the lower lips 237 of the main body 235 of control handle 215 and control handle.Open slot 241 closures between main body 235 and lower lips 237, and main body moves to lower lips and engages.The continuing of control handle 215 opened the motion causative subject lower lips 237 that pivots jointly, promotes articulated slab 227a, and 227b upwards passes through co-planar locations.This is with ring component 223a, and 223b moves to open position, shown in Figure 28-30.For closed hoop parts 223a, 223b also makes mechanism 201 return to locked position, and the operator pushes away ring component together.

In this ring mechanism 201, the being articulated and connected protection locking element 249 between intermediate connector 267 and carriage release lever 245 is avoided slightly moving both vertically of control handle 215 in the control handle pivot action process.Hinge 272 provides the pivot between intermediate connector 267 and the lock portion 248 to connect, and intermediate connector is pivoted up and down with respect to lock portion and locking element 249.

Figure 33-53 shows the circular clip mechanism 301 of another embodiment.Mechanism 301 is similar to that the front is described and in the mechanism 101 shown in Fig. 1-19, but comprises the intermediate connector 366 of the intermediate connector 167 that is different from Fig. 1-19.The parts of the ring mechanism 301 corresponding with the parts of the ring mechanism 101 of Fig. 1-19 are represented with the same reference numerals that adds " 200 ".In this embodiment, intermediate connector 366 is bent wire, has the first end 366a, the second end 366b and the arcuate section 366c between first and second end (Figure 50-53).The first end 366a is included in the small gap 366e between starting point wiry and the end point.

As Figure 35, shown in 37 and 38, the diagram carriage release lever 345 of this embodiment comprises the elongated lock portion 348 with three locking elements 349.Intermediate connector 366 is connected in lock portion 348.More specifically, lock portion 348 comprises the protuberance 371 of groove 347 and next-door neighbour's groove 347.The second end 366b of intermediate connector 366 is contained in the groove 347, and the part that intermediate connector is close to its second end is extended below protuberance 371.Except groove 347 and protuberance 371, the shape of the locking element 349 of lock portion 348 is similar to the locking element 149 of foregoing mechanism 101.Shown in Figure 36-38, intermediate connector 366 is connected in flat control handle 315 at upper lip 336 places of control handle.The first end 366a of intermediate connector 366 is assemblied in the hole 336a on the upper lip 336 of control handle 315, makes the pivoting action of control handle produce the translational motion of carriage release lever 345.

The opening operation of this mechanism 301 is similar to the opening operation of previously described mechanism 101,201 (Fig. 1-32).Figure 34 and 36-38 show the ring mechanism 301 that is in closed and locked position.In order to open ring component 323a, 323b, control handle 315 outside and pivot (Figure 39-41) downwards.As shown in figure 39, lower lips 337 beginning of control handle 315 upwards pushes away on the bottom surface of 327b at articulated slab 327a, and the upper lip 336 of control handle with carriage release lever 345 and locking element 349 be pulled to articulated slab on opening 329a, 329b, the not lock position of 329c alignment.Being connected between the lock portion 348 of carriage release lever 345 and intermediate connector 366 can make intermediate connector slightly upwards pivot with respect to lock portion, thereby the adjusting control handle slightly moves upward when control handle pivots.339 deflections of flexible bridge portion and tensioning between the lower lips 337 of the main body 335 of control handle 315 and control handle.Open slot 341 closures between main body 335 and lower lips 337, and main body moves to and engages (Figure 40) with lower lips.The continuing of control handle 315 opened the motion causative subject lower lips 337 that pivots jointly, promotes articulated slab 327a, and 327b upwards passes through co-planar locations.This is with ring component 323a, and 323b moves to open position, shown in Figure 42-45.Arcuate section 366c is not distortion basically in motion process.

For

closed hoop parts

323a, 323b also makes mechanism 301 return to locked position, and the operator can make control handle 315 upwards and inwardly pivot.Shown in Figure 46 and 47, this upper lip 336 with control handle 315 moves to and articulated slab 327a, the upper surface contact (if it does not also contact with the articulated slab upper surface) of 327b.Upper lip 336 and articulated slab 327a, the upper surface of 327b engages, and begins they are pushed away downwards, but the initial hinge plate motion of the elastic force of the housing 311 of mechanism 301 opposing.Carriage release lever 345 can initially travel forward along with the motion of upper lip 336, and the leading edge 355a that makes locking element 349 is near articulated slab 327a, the protuberance 382 of 327b (if locking element also not near).When control handle 315 continues to pivot, near the further translational motion of locking element 349 opposing carriage release levers 345.

As shown in figure 47, the arcuate section 366c of intermediate connector 366 is compressed (or being bent outwardly to more obvious bowed shape) so that control handle 315 continues to pivot.This relative motion between control handle 315 and the locking element 349 causes producing in the intermediate connector 366 tension force.When closing motion this moment, if control handle 315 is at articulated

slab

327a, 327b pivot downwards by before their co-planar locations (that is, at ring component 323a, before the 323b closure) be released, the tension force in the intermediate connector 366 will make control handle automatically rebound (and pushing away) to its starting position.In this ring mechanism 301, the compressibility of intermediate connector 366 can make control handle 315 pivot, and with articulated

slab

327a, 327b moves down, so that made ring component 323a before the locked position that locking element 349 is pushed into the articulated slab back, the 323b closure.

Shown in Figure 48 and 49, the continuation closing motion of control handle 315 causes upper lip 336 with interconnective articulated

slab

327a, and 327b pivots downwards.In case articulated

slab

327a, 327b have just passed through co-planar locations, the elastic force of housing pushes away them downwards, closed hoop parts 323a, 323b.Along with articulated

slab

323a, 323b pivots downwards, and the inclination leading edge 355a of locking element 349 allows locking element and carriage release lever 345 to move (shown in Figure 48 and 49) to the left.In case articulated

slab

327a, 327b cross the inclination leading edge 355a of locking element 349, they just no longer resist travelling forward of locking element and carriage release lever 345.Locking element 349 moves at articulated slab 327a along with control handle 315 now, their locked position of 327b back.Simultaneously, be compressed and the tension force of generation release in intermediate connector 366, and further locking element 349 be pushed into locked position.Bridge portion 339 and intermediate connector 366 return to their slack position.Mechanism 301 is in position shown in Figure 43 once more.

When introducing the part of circular clip mechanism, " one, the implication of " being somebody's turn to do " and " described " are to have one or more these parts to article.Term " comprises ", " comprising " and " having " with and various variation be meant and included that its implication is other part that can exist except the part of listing.In addition, using term " preceding " and " back " and their distortion, or use other directions and directionality term, be for convenience, but these parts is without any need for special location.

Owing to can make different variations in the foregoing description under the situation that does not break away from the utility model scope, all the elements that therefore comprise in the above description and expression in the accompanying drawings all should be thought indicative, rather than restrictive.
