1freely rotate.
Fig. 2 to Fig. 7 represents the paper-retaining device 100 in a kind of state (being called " ring closed condition "), in a state in which, lever 114 is positioned at ring closed position and the free end 104a of the free end 106a and column piece 104 that encircle part 106 contacts and coordinates, to form two rings of closing.In this ring closed condition, on the top being bent upwards part 136 of curved bar 108, roller 130 to be positioned on recess 134 and to engage (see figure 1) with recess 134, thus oppresses curved bar 108 towards base 102, so that arch part 106 is remained on ring closed position.
When lever 114 relative to base 102 and column piece 104 around axis S
1-S
1along arrow W
1indicated direction (see figure 2) and away from ring closed position move pivotally (such as operating finger 124 by user) time, roller 130 is disengaged with the recess 134 of curved bar 108.Meanwhile, toe part 126 is again around axis S
1-S
1and along arrow W
1the equidirectional of instruction moves pivotally away from base 102, to engage with curved bar 108 from below and to act on curved bar 108, thus makes curved bar 108 around axis R
1-R
1and move pivotally away from base 102.
Thus, when lever 114 is along arrow W
1when indicated direction is pivotally moved to the position (being called " ring open position ") shown in Fig. 8 to Figure 12, arch part 106 moves pivotally and is disengaged with column piece 104 and contacts, thus opens two rings.When device 100 is in this ring open mode, can from column piece 104 or arch part 106, takes out multiple paper or multiple paper be inserted in column piece 104 or arch part 106.
When device 100 is in this ring open mode, the recess 138 being bent downwardly part 140 that roller 130 is positioned at curved bar 108 is connected (see figure 2) with recess 138.The radius of curvature of recess 134 is less than the radius of curvature of recess 138.
Joint between the roller 130 of recess 138 and lever 114 limits the scope upwards moved pivotally of curved bar 108 and lever 114 at arrow W
1the scope of the pivoting action in indicated direction.Specifically, when lever 114 has been positioned at the ring open position shown in Fig. 8 to Figure 12, at arrow W
1direction on any further pivoting action (roller 130 will be caused around axis S
1-S
1further move pivotally in a same direction) will the corresponding of toe part 126 be caused upwards to move pivotally, this can make again curved bar 108 upwards move pivotally further, and directly contrary with the further pivoting action of roller 130.Thus, at arrow W
1in indicated direction, lever 114 does not exceed any pivoting action of position shown in Fig. 8 to Figure 12, and curved bar 108 does not exceed the pivoting action upwards further of position shown in Fig. 8 to Figure 12 yet.
When lever 114 from Fig. 8 to Figure 12 shown in ring open position return to the ring closed position shown in Fig. 2 to Fig. 7, roller 130 is also around axis S1-S1 pivotable, to engage with the recess 134 of curved bar 108 and to oppress the recess 134 of curved bar 108 to base 102, thus curved bar 108 pivotable (and thus making arch part 106 pivotable) is made to return to the ring closed position shown in Fig. 2 to Fig. 7.
Can see, no matter lever 114 is positioned at ring closed position or ring open position, still during pivoting action between these two positions, always finger 124 is between two rings formed by column piece 104 and arch part 106.Can also see, the pivot axis S of lever 114

1between roller 130 and toe part 126.
Figure 13 shows that the parts of paper-retaining device second embodiment of the invention, wherein this device is generally designated 200.Can see, the structure of device 200 is similar to the structure of device 100 discussed above, but more simpler than the structure of device 100.
Device 200 comprises and is roughly flat base 202, this base 202 has firmly fixed two column pieces 204.A pair arch part 206 is connected to each other by curved bar 208, and this is integrally formed by curved bar 208 arch part 206.Thus, arch part 206 and curved bar 208 move each other simultaneously.
Curved bar 208 is connected with a pair fixture 210, and this to be positioned on base 202 fixture 210 and to be integrally formed with this base 202, makes curved bar 208 can relative to base 202 and column piece 204 around the axis R close to base 202
2-R
2pivotable.By such layout, curved bar 208 can pivotable, to make arch part 206 pivotable (arch part 206 can move with curved bar 208) between ring closed position and ring open position simultaneously, when ring closed position, the arch free end 206a of part 206 contacts with the free end 204a of column piece 204 and coordinates, to form two rings (as shown in Figure 14 to Figure 20) of closing; When ring open position, the arch free end 206a of the part 206 and free end 204a of column piece 204 disengages and matching relationship, thus is opened (as shown in Figure 21 to Figure 26) by ring.
The plate 212 be integrally formed with base 202 upwards extends away from base 202.Lever 214 is pivotally mounted on plate 212 by rivet 216 in the position of proximate base 202.Specifically, lever 214 has hole 218 and plate 212 has the hole 220 of proximate base 202.Rivet 216 is contained in these two holes 218,220, to be pivotally mounted on plate 212 by lever 214.By such layout, when device 200 suitably assembles (as Suo Shi Figure 14 to 26), lever 214 can relative to base 202, plate 212 and column piece 204 around perpendicular to axis R
2-R
2rivet 216, hole 220 and hole 218 common longitudinal axis move pivotally.
Lever 214 is made up of plastic material, and comprises the main parts 222 with two longitudinal ends.Longitudinally hold as finger 224 for one of main part 222, and the contrary longitudinal direction end of main part 222 is for having the toe part 226 of wall portion 227.Toe part 226 and wall portion 227 roughly perpendicular to one another.The lever 214 comprising main part 222, finger 224, toe part 226 and wall portion 227 is integrally formed by one piece of plastic material, thus all these parts can move each other simultaneously.
Get back to curved bar 208, the mid portion close to curved bar 208 is the sweep 236 upwards with the first recess 234, and the downward sweep 240 of the vicinity of curved bar 208 sweep 236 upwards has the second recess 238.The radius of curvature of the first recess 234 is less than the radius of curvature of the second recess 238.
Figure 14 to Figure 20 represents the paper-retaining device 200 in a kind of state (being called " ring closed condition "), in a state in which, lever 214 is positioned at ring closed position and the free end 204a of the free end 206a and column piece 204 that encircle part 206 contacts and coordinates, to form two rings of closing.In this ring closed condition, in the upside being bent upwards part 236 of curved bar 208, the bending protuberance 242 of lever 214 to be positioned on the first recess 234 and to engage with the first recess 234, thus oppresses curved bar 208 towards base 202, so that arch part 206 is remained on ring closed position.
When lever 214 relative to the longitudinal axis of base 202 and column piece 204 surrounding hole 220 at arrow W
2in indicated direction (see Figure 14) and away from ring closed position move pivotally (such as by user's manual operation) time, protuberance 242 departs from the joint with the recess 234 of curved bar 208.Meanwhile, toe part 226 again around the hole 220 of plate 212 longitudinal axis and at arrow W
2the equidirectional of instruction moves pivotally, to engage with curved bar 208 from below and to act on curved bar 208, thus makes curved bar 208 around axis R
2-R
2move pivotally away from base 202.
Thus, when lever 214 is at arrow W
2when indicated direction being pivotally moved to the ring open position shown in Figure 21 to Figure 26, arch part 206 move pivotally and depart from the joint of column piece 204 with contact, thus open two rings.When device 200 is in this ring open mode, can from column piece 204 or arch part 206, take out multiple paper or multiple paper be inserted in column piece 204 or arch part 206.
When device 200 is in this ring open mode, the recess 238 being bent downwardly part 240 that protuberance 242 is positioned at curved bar 208 engages (see Figure 14) with recess 238.
The scope upwards moved pivotally of the joint restriction curved bar 208 between the protuberance 242 of recess 238 and lever 214 and lever 214 are at arrow W
2the scope of the pivoting action in indicated direction.Specifically, when lever 214 has been positioned at the ring open position shown in Figure 21 to Figure 26, at arrow W
2direction on any further pivoting action (longitudinal axis causing lever 214 around the hole 220 of plate 212 is further moved pivotally in a same direction) the corresponding of toe part 226 will be caused upwards to move pivotally, this can make again curved bar 208 upwards move pivotally further, and contrary with the further pivoting action of the lug boss 242 of lever 214.Thus, in arrow W2 indicated direction, lever 214 does not exceed the pivoting action of the position shown in Figure 21 to Figure 26, and curved bar 208 does not exceed the pivoting action upwards further of the position shown in Figure 21 to Figure 26 yet.
When lever 214 is pivoted to ring open position from ring closed position, when moving to ring open mode to make device 200 from ring closed condition, wall portion 227 rises to this wall portion from the top position (as shown in Figure 21 and Figure 25) that base 202 rises from the lower position (as shown in Figure 14 and Figure 19) close to base 202, thus the contact of realization and the upwards curved bar 208 of pivotable.
With particular reference to Figure 21 to Figure 25, can see, when device 200 is in ring open mode (in a state in which, arch part 206 departs from and the contact of column piece 204 and joint), the wall portion 227 of lever 214 is positioned at top position, and wall portion 227 is towards the side of plate 212 and curved bar 208 towards a side contacts of encircleing part 206.Find in practice, when there is no wall portion 227, sometimes may pivotable curved bar 208 and departing from and the contact of toe part 226 forcibly, such as, by pulling arch part 206 with column piece 204 further away from each other forcibly, thus cause the damage to device 200.Therefore, wall portion 227 contributes to limiting the scope of curved bar 208 away from the pivoting action of base 202.
When lever 214 is from ring open position (as shown in Figure 21 to Figure 26) pivotable winding closed position (as shown in Figure 14 to Figure 20), lug boss 242 is also around the longitudinal axis pivotable in the hole 220 of plate 212, to engage with the recess 234 of curved bar 208, act on the recess 234 of curved bar 208 and oppress the recess 234 of curved bar 208 to base 202, thus making curved bar 208 pivotable (thus making arch part 206 pivotable) return to ring closed position as shown in Figure 14 to Figure 20.
Can see, no matter lever 214 is in ring closed position or ring open position, still, during moving pivotally between these two positions, the longitudinal direction end contrary with toe part 226 with lug boss 242 of lever 214 is always by column piece 204 with encircle between two rings that part 206 formed.Can also see, on the one hand, the pivot axis of lever 214 between lug boss 242 and toe part 226, on the other hand, also between jut 242 and wall portion 227.
Also can see, device 100 and device 200 are the structure not having spring.
Device 100 and device 200 all can be fixed in substrate, such as by bolt, rivet or other securing member, substrate such as can for the lid be made up of hardboard, plastics, metal or its composition, and to form file, such as document case or file keep thing.
