The specific embodiment
Figure 1 shows that described mechanism represents with 100 usually according to the decomposition diagram of the paper-retaining mechanism of the lever-arch file folder mechanism form of first embodiment of the invention.Described mechanism 100 comprises the base of being made by metallic plate 102.Substantially extend upward from described base 102 with base 102 integrally formed gripper shoes 104.
One coupled columns 106 is firmly secured to base 102.Spaced a pair of arched member 108 is connected to each other by center crank bar 110 and forms with these center crank bar 110 integral body, thereby described arched member 108 and toggle-action lever 110 can same moved further.
Toggle-action lever 110 cooperates with base 102 by a pair of anchor clamps 112, only illustrates this among Fig. 1 to one in the anchor clamps 112.By such setting, arched member 108 can (be called " detent position " in primary importance around axis M-M, as Fig. 5 to shown in Figure 11) and the second place (be called " open position ", as Figure 12 to shown in Figure 17) between pivot, in described primary importance, the free end 114 of arched member 108 contacts with the free end 116 of post 106 and fluid-tight engagement, thereby form the ring of two sealings, in the described second place, the free end 114 of arched member 108 disengages and fluid-tight engagement with the free end 116 of post 106, thereby opens described ring.When described mechanism 100 was in the ring seal state, the ring of described a pair of sealing can keep being installed with the paper in hole; And when described mechanism 100 is in the ring open mode, can from post 106 and arched member 108, take out the paper that is installed with the hole, the paper that perhaps will be installed with the hole inserts in post 106 and the arched member 108.
One side of leaf spring 118 cooperates with base 102, and opposite side acts on the downside of toggle-action lever 110, with arched member 108 towards the open position bias voltage.
The circular slab 126 of lever 122 has a plurality of holes 146 along its periphery.As shown in Figure 3, when assembling during lever assembly 120, each tooth 148 releasably cooperates with corresponding hole 146 and is contained in this hole 146.As can be seen, each tooth 148 is shaped as triangle.
With reference now to Fig. 5,, lever 122 diagrams are in upper position.Because the shape of circle 140 tooth 148 and with the cooperating of the hole 146 of the circular slab 126 of lever 122, lever 122 will produce along the downward pivoting action of the indicated direction of arrow G and enclose 140 (thereby taking turns 130) rotatablely moving along the correspondence of equidirectional.Then, when lever 122 is positioned at lower position shown in dotted lines in Figure 5, if discharge downward active force, by spring 150 the upper end applied upwards biasing force can make lever 122 turn back to the upper position shown in the solid line.Return at this of lever 122 and to move, because the shape of the tooth 148 of circle 140, tooth 148 will be let slip in hole 146.Thereby described circle 140 and wheel 130 can keep static upwards returning of lever 122 in the moving process.
This means, though lever 122 can be done pivoting action in the opposite direction along the indicated direction of arrow G among Fig. 5 and with this side, take turns 130 and circle 140 only can rotate along the indicated direction of arrow G.
When described mechanism 100 is in Fig. 6 to the ring seal state shown in Figure 11 the time, one of them tooth 136 of wheel 130 acts in the portion that is bent upwards 156 of toggle-action lever 110, overcoming the upwards biasing force of leaf spring 118, and arched member 108 is cooperated with post 106, to form the ring of two sealings.
When the lever 122 of lever assembly 120 along the arrow G shown in Fig. 5 be directed downwards pivot (for example, user's manual operation) time, lever 122 makes wheel 130 (thereby actuation part 134) correspondingly along identical direction rotation.This tooth 136 that will make script and bend 156 contact and act on bend 156 disengages with bend 156, and next groove 138 will subsequently be entered in the state of bend 156.
When wheel 130 is positioned at this position, if the downward power of release action on toggle-action lever 110, bar 110 will pivot around axis M-M under the effect of the biasing force that makes progress of leaf spring 118, so that arched member 108 pivots away from post 106, thereby open described ring, extremely shown in Figure 17 as Figure 12.
When the downward power of release action on lever 122, lever 122 will be back to the upper position shown in the solid line among Fig. 5 in the opposite direction along the side with arrow G then.As mentioned above, this can not make wheel 130 produce corresponding rotatablely moving, and described mechanism 100 will keep this ring open mode.
When lever 122 pivots downwards along the direction of arrow G again, this will make wheel 130 produce and move along the corresponding rotation of identical direction.This action will make next tooth 136 subsequently of actuation part 134 contact with the bend 156 of toggle-action lever 110 and cooperate, thereby arched member 108 is back pivoted to cooperate with post 106, form the ring of two sealings.Once more, when the downward power of release action on lever 122, lever 122 will be back to upper position, and can not make wheel 130 make rotatablely moving of any correspondence.
Because the actuation part 134 of wheel 130 has six teeth 136 and six grooves 138, thereby each downward pivoting action of lever 122 will make wheel 130 along identical direction rotation 30 degree.In addition, as can be seen, in operating process, take turns 130, promptly along the indicated direction rotation of arrow G along a direction rotation.
Figure 18 shows that the decomposition diagram according to the lever-arch file folder mechanism of second embodiment of the invention, described mechanism represents with 200 usually.The main distinction between this mechanism 200 and the said mechanism 100 is the structure of its lever assembly 220, and is extremely shown in Figure 21 as Figure 19.
Figure 19 to Figure 21 represents lever assembly 220, and this lever assembly 220 comprises the lever 222 with circular slab 226, and this circular slab 226 is provided with a plurality of holes 246 along its periphery.Lever assembly 220 also comprises the wheel 230 with end plate 232, this end plate 232 and actuation part 234 whole formation.Actuation part 234 is a hexagram, has tooth 236 and six medial launders 238 that six isogonisms are provided with.Middle bluff piece 240 is arranged on the circular slab 226 of lever 222 and takes turns between 230 the actuation part 234.
As shown in figure 22, when having assembled mechanism 200, lever 222 can center on axis L between upper position (shown in solid line) and lower position (shown in dotted line)
2-L
2(referring to Figure 18 and Figure 21) pivots.Because the shape of the tooth 248 of bluff piece 240, be specially the sloping edge 260 of each tooth 248, lever 222 (promptly along the indicated direction of arrow H) downwards is pivoted to position, its underpart in the portion position from it, so that bluff piece 240 (thereby taking turns 230) is done corresponding rotatablely moving along identical direction.
When the downward power of release action on lever 222, lever 222 is back to upper position (referring to Figure 18) in the effect lower edge direction opposite with arrow H of the upwards biasing force of the upper arm of spring 250.Upwards return in the pivot motion course at this of lever 222, still because the sloping edge 260 of each tooth 248, lever 222 will pivot with respect to bluff piece 240, and can not make bluff piece 240 (thereby taking turns 230) make rotatablely moving of any correspondence.
When mechanism 200 is in when Figure 23 is to the ring seal state shown in Figure 28, one of them tooth 236 of the actuation part 234 of wheel 230 acts in the portion that is bent upwards 256 of the toggle-action lever 210 that connects two arched members 208, makes arched member 208 and two post 206 fluid-tight engagement that are fixed in the base 202 of mechanism 200.
When lever 222 when the portion position is pivoted to position, its underpart downwards from it, this makes bluff piece 240 and wheel 230 do corresponding rotatablely moving, thereby next-door neighbour's the groove 238 that makes actuation part 234 is towards the bend 256 of toggle-action lever 210.Owing to do not act on the downward power on the bend 256, thereby allow that the leaf spring 218 that cooperates with base 202 upwards pivots, so that toggle-action lever 210 pivots, thereby arched member 208 is pivoted away from post 206, to open two rings that form by arched member 208 and post 206.When the downward power of release action on lever 222, lever 222 is back to its upper position, and take turns 230 and bluff piece 240 keep static.Thereby described mechanism 200 will present its as Figure 29 to ring open mode shown in Figure 34.
When again lever 222 being pressed to position, its underpart, this will make bluff piece 240 and wheel 230 make corresponding rotatablely moving, thereby the next-door neighbour's of actuation part 234 tooth 236 cooperates with the portion that is bent upwards 256 of toggle-action lever 210, thereby make arched member 108 again with post 206 fluid-tight engagement, to form the ring of two sealings.When the downward power of release action on lever 222, lever 222 is back to its upper position, and bluff piece 240 and wheel 230 keep static.Thereby described mechanism 200 presents as Figure 23 to ring seal state shown in Figure 28.
Shown in Figure 35 is decomposition diagram according to the lever-arch file folder mechanism of third embodiment of the invention, and described mechanism represents with 300 usually.This mechanism 300 comprises the base of being made by metallic plate 302.Substantially extend upward from this base 302 with base 302 integrally formed gripper shoes 304.One coupled columns 306 is firmly secured to base 302.Spaced a pair of arched member 308 is connected to each other by center crank bar 310 and forms with these center crank bar 310 integral body, thereby described arched member 308 and toggle-action lever 310 can same moved further.
Lever assembly is assemblied in gripper shoe 304 by rivet 352,354.Lever assembly comprises lever 322, wheel 330, middle ratchet 340 and a pair of resilent finger 362.When lever assembly cooperated with gripper shoe 304, lever 322 can center on common axis L
3-L
3Pivot, and take turns 330 and finger 362 also can center on this common axis L
3-L
3Rotation.
To shown in Figure 39, finger 362 and ratchet 340 are contained in the groove 364 of actuation part 334 of wheel 330 as Figure 36.Ratchet 340 can rotate in groove 364 with respect to actuation part 334.Actuation part 334 has six teeth 336 and six medial launders 338.
About finger 362, this finger 362 cooperates with groove 364, with the wheel 330 same moved further.These two finger 362 extend in the groove 364, to match with each tooth 348 that radially extends from ratchet 340.The number of finger 362 is certainly different, for example, can be one, three, four or more a plurality of finger 362.
Be back to Figure 35, ratchet 340 has two arcuate ridges 366 that diametric(al) is relative, and these two arcuate ridges 366 are arranged on ratchet 340 on the first type surface 368 of the circular slab 326 of lever 322.The circular slab 326 of lever 322 comprises two arcuate sockets 346, and the size of these two arcuate sockets 346 and structure are set to each arcuate socket 346 to be held ridge 366 of ratchet 340 and cooperate with this ridge 366, to be synchronized with the movement.For example, the ridge 366 of ratchet 340 can fixedly secure by the mode of pressure fitted in the hole 346 of circular slab 326.
With reference to Figure 37, because the orientation of the elastic force of finger 362 self and the tooth 348 of ratchet 340, ratchet 340 can rotate with respect to wheel 330 along the direction opposite with arrow P but finger 362 prevents ratchet 340 with respect to wheel 330 along the indicated direction rotation of arrow P.
When the mechanism 300 of correct assembling is positioned at its ring seal state (extremely shown in Figure 45 as Figure 40), one of them tooth 336 of actuation part 334 acts in the portion that is bent upwards 356 of toggle-action lever 310, the ring seal position that forms two sealings so that arched member 308 remains on that this arched member 308 cooperates with post 306.
When lever 322 from it portion position (as Figure 40 to shown in Figure 45) when being pivoted to position, its underpart (shown in Figure 46 to Figure 51) downwards, ratchet 340 is made simultaneously and being rotatablely moved.Because the orientation of the tooth 348 of ratchet 340, and with the cooperation of wheel 330 finger that cooperate 362, take turns 330 and also do accordingly and rotatablely move along identical direction.This will make wheel next-door neighbour's groove 338 of 330 towards the bend 356 that makes progress, thus allow arched member 308 by leaf spring 318 (this leaf spring 318 cooperates with base 302) away from described post 306 pivot that makes progress, opening ring, thereby make mechanism 300 move to the ring open mode.
When the downward power of release action on lever 322, lever 322 returns (under the effect of the biasing force that makes progress of spring 350) to its upper position.Upwards return in the pivoting action at this of lever 322, because the said structure between finger 362 and the ratchet 340, ratchet 340 will be with respect to wheel 330 rotations in the groove 364 of wheel 330, do not take turns 330 and do any rotatablely moving and can not make.This means that in the return movement process of lever 322 wheel 330 keeps static.
When lever 322 pivots downwards once more, next of actuation part 334 tooth 336 subsequently will cooperate with the portion that is bent upwards 356 of bar 310, thereby the biasing force that makes progress that overcomes leaf spring 318 makes arched member 308 and post 306 fluid-tight engagement, to seal two rings.Then, allow that lever 322 is back to its upper position, and can not make wheel 330 make corresponding rotatablely moving.
Thereby, shown in Figure 52, have only lever 322 just can make wheel 330 do corresponding rotatablely moving along the downward pivoting action of the indicated direction of arrow R.
Figure 53 is depicted as the decomposition diagram according to the lever-arch file folder mechanism of four embodiment of the invention, and described mechanism represents with 400 usually.This mechanism 400 has base 402, and this base 402 has two posts 406 that are firmly secured to this base 402.Lever assembly 420 cooperates with gripper shoe 404, and this gripper shoe 404 extends upward substantially with base 402 whole formation and from this base 402, and Figure 54 to Figure 59 can more clearly express.
Cooperate with base 402 by toggle-action lever 410 a pair of arched members 408 connected to one another, between detent position and open position, to pivot, at detent position, arched member 408 cooperates with post 406, to form the ring of two sealings, at open position, arched member 408 breaks away from described post 406 and cooperates, thereby opens described ring.
When the downward power of release action on lever 422, lever 422 can be back to its upper position (shown in Figure 67 to Figure 69), and can not make wheel 430 make corresponding rotatablely moving.
If lever 422 is pivoted to position, its underpart once more downwards, then next-door neighbour's tooth 436 of actuation part 434 can cooperate with the portion that is bent upwards 456 of toggle-action lever 410 and act on this bend 456, thereby the revolution of arched member 408 pivots is cooperated, shown in Figure 70 to Figure 72 with post 406.When the downward power of release action on lever 422, lever 422 can be back to the upper position shown in Figure 73 to Figure 75, also can not make wheel 430 make rotatablely moving of any correspondence.
Figure 76 to Figure 78 more clearly shows cooperating between finger 462 and the ratchet 440.From Figure 76, as can be seen, finger 462 cooperates with the tooth 448 of ratchet 440.When the downward power of release action on lever 422, lever 422 upwards pivots.Because the shape and the orientation of the tooth 448 of ratchet 440, lever 422 can at first overcome the inside biasing force of line 470 and upwards be pivoted to the centre position shown in Figure 77, and in this centre position, finger 462 is left the center of the groove 464 of actuation part 434.Then, lever 422 continues upwards to be switched to upper position (shown in Figure 78), and at this upper position, finger 462 cooperates with the tooth 448 of ratchet 440 again.Because described line 470 is flexible, thereby finger 462 can be for stiff.
As can be seen, the pivoting action that makes progress of lever 422 can not make actuation part 434 (thereby taking turns 430) make corresponding rotatablely moving.In other words, in the upwards pivot motion course of lever 422, it is static that wheel 430 and actuation part 434 can keep.
On the other hand, if lever 422 pivots downwards, promptly along the rotation of the indicated direction of arrow S among Figure 78, then because the shape of the tooth 448 of ratchet 440 and the cooperation between orientation and finger 462 and the tooth 448, actuation part 434 and wheel 430 can be done rotatablely moving of correspondence along identical direction.
Figure 79 is depicted as the decomposition diagram according to the lever-arch file folder mechanism of fifth embodiment of the invention, and described mechanism represents with 500 usually.This mechanism 500 comprises base 502, and this base 502 has whole formation and upwardly extending substantially gripper shoe 504.Two posts 506 fixedly secure on base 502, and a pair of arched member 508 cooperates with base 502, with respect to base 502 and post 506 pivoting actions.Described arched member 508 is connected to each other with the 510 whole formation of center crank bar and by this toggle-action lever 510.
Described mechanism 500 also comprises lever assembly 520, and Figure 80 to Figure 85 more clearly shows this lever assembly 520.Lever assembly 520 has: can manually operated lever 522, and this lever 522 has arm 524 and almost circular plate 526; Wheel 530; And middle matching board 540.
As can be seen, a toothrow 548 extends away from the first type surface of matching board 540, and cooperates with a corresponding toothrow 570 that first type surface away from the circular slab 526 of lever 522 extends.
When on the gripper shoe 504 that lever assembly 520 is installed in described mechanism 500, lever 522 can center on common axis L
5-L
5Pivot, and matching board 540 and wheel 530 can center on this common axis L
5-L
5Rotation.
When described mechanism 500 was in the ring seal state, shown in Figure 86 to Figure 91, arched member 508 was fitted to each other with post 506, with the ring of two sealings of the paper that is formed for keeping being installed with the hole.In this position, one of them tooth 536 of wheel 530 acts on the toggle-action lever 510, to keep the engagement relationship of arched member 508 and post 506.
Then, lever 522 can downward (promptly along the indicated direction of arrow W among Figure 86) pivot away from its upper position, shown in Figure 86 to Figure 91.Because the orientation of the tooth 548 of matching board 540 and the tooth 570 of lever 522, and because the relation of cooperatively interacting of described tooth, the downward pivoting action of this of lever 522 will make matching board 540 (thereby taking turns 530) do corresponding rotatablely moving along identical direction, and then the next-door neighbour's groove 538 that makes wheel 530 is directly towards toggle-action lever 510.Then, toggle-action lever 510 can be under the effect of the leaf spring 518 that cooperates with base 502 and pivot, so that arched member 508 pivots away from post 506, thereby opens described two rings.
When the downward power of release action on lever 522, lever 522 is by spring 550 bias voltage upwards.Upwards return in the pivot motion course at this of lever 522, because the orientation of the tooth 548 of matching board 540 and the tooth 570 of lever 522, and because the elastic force of helical spring 544, circular slab 526 and lever 522 can rotate with respect to matching board 540 (thereby taking turns 530).This means that when lever 522 is back to its upper position wheel 530 keeps static, and mechanism 500 remains in its ring open mode, shown in Figure 92 to Figure 98.Thereby lever 522 only can pivot with respect to matching board 540 (thereby taking turns 530) along a direction.
Figure 99 and Figure 100 represent lever 522 moving between upper position (representing with solid line) and lower position (being represented by dotted lines).
Each above-mentioned paper-retaining mechanism 100,200,300,400,500 can be fixed in substrate (as the cover plate of being made by cardboard, plastics, metal or its composition) by for example rivet or screw, thereby the formation paper-retaining device is as document holder or file (box file).
