2Pivot.By such layout, curved bar 208 can pivot, so that arch part 206 pivots between ring closed position and ring open position (arch part 206 can move simultaneously with curved bar 208), when the ring closed position, the free end 206a of arch part 206 contacts with the free end 204a of column piece 204 and cooperates, to form two rings of closing (extremely shown in Figure 20 such as Figure 14); When the ring open position, the free end 206a of arch part 206 and the free end 204a of column piece 204 disengage and matching relationship, thereby ring are opened (extremely shown in Figure 26 such as Figure 21).
The plate 212 integrally formed with base 202 extends upward away from base 202.Lever 214 is pivotally mounted on the plate 212 by rivet 216 in the position of proximate base 202.Specifically, lever 214 has the hole 220 that hole 218 and plate 212 have proximate base 202.Rivet 216 is contained in these two holes 218,220, so that lever 214 is pivotally mounted on the plate 212.By such layout, when device 200 suitably assembles (shown in Figure 14 to 26), lever 214 can center on perpendicular to axis R with respect to base 202, plate 212 and column piece 204
2-R
2The common longitudinal axis pivoting action in rivet 216, hole 220 and hole 218.
Getting back to curved bar 208, is the sweep that makes progress 236 with first recess 234 near the mid portion of curved bar 208, and the downward sweep 240 of the sweep 236 that makes progress of the vicinity of curved bar 208 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 is illustrated in the paper-retaining device 200 in a kind of state (being called " ring closed condition "), in this state, the free end 206a that lever 214 is positioned at ring closed position and arch part 206 contacts with the free end 204a of column piece 204 and cooperates, to form two rings of closing.In this ring closed condition, the upside that is bent upwards part 236 at curved bar 208, the crooked protuberance 242 of lever 214 is positioned on the first recess 234 and with the first recess 234 and engages, thereby towards base 202 compressing curved bars 208, remains on the ring closed position will encircle part 206.
When lever 214 centers on the longitudinal axis in hole 220 at arrow W with respect to base 202 and column piece 204
2(see Figure 14) on the indicated direction and during away from ring closed position pivoting action (for example by user's manual operation), protuberance 242 breaks away from and the engaging of the recess 234 of curved bar 208.Simultaneously, toe spare 226 is again around the longitudinal axis in the hole 220 of plate 212 and at arrow W
2Move pivotally on the equidirectional of indication, engaging and to act on the curved bar 208 with curved bar 208 from the below, thereby make curved bar 208 center on axis R
2-R
2Away from base 202 pivoting actions.
Thereby, when lever 214 at arrow W
2When being pivotally moved to Figure 21 to ring open position shown in Figure 26 on the indicated direction, arch part 206 pivoting actions and break away from the joint of column piece 204 with contact, thereby open two rings.When device 200 is in this ring open mode, can from column piece 204 or arch part 206, open or plurality of sheets of paper is opened in insertion column piece 204 or the arch part 206 by the taking-up plurality of sheets of paper.
When device 200 was in this ring open mode, protuberance 242 was positioned on the recess that is bent downwardly part 240 238 of curved bar 208 and with recess 238 and engages (seeing Figure 14).
The scope of the upwards pivoting action 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 on the indicated direction.Specifically, when lever 214 has been positioned at Figure 21 to ring open position shown in Figure 26, at arrow W
2Direction on any further pivoting action (will cause that lever 214 is around the longitudinal axis in the hole 220 of plate 212 further pivoting action on identical direction) will cause the corresponding upwards pivoting action of toe spare 226, this can make again further pivoting action upwards of curved bar 208, and opposite with the further pivoting action of the lug boss 242 of lever 214.Thereby on arrow W2 indicated direction, lever 214 does not exceed Figure 21 to the pivoting action of position shown in Figure 26, and curved bar 208 does not exceed Figure 21 to the pivoting action that further makes progress of position shown in Figure 26 yet.
When lever 214 is pivoted to the ring open position from the ring closed position, move to ring during open mode so that install 200 from the ring closed condition, wall section 227 rises to this wall section from the top position (such as Figure 21 and shown in Figure 25) that base 202 rises from the lower position (such as Figure 14 and shown in Figure 19) near base 202, thereby realizes and the contacting of the curved bar 208 of pivot upwards.
With particular reference to Figure 21 to Figure 25, can see, when device 200 be in ring during open mode (in this state, 206 disengagings of arch part contact and joint with column piece 204), the wall section 227 of lever 214 is positioned at the top position, and wall section 227 is towards a side of plate 212 and curved bar 208 side contacts towards arch part 206.Find in practice, when not having wall section 227, sometimes may pivot forcibly curved bar 208 and break away from and the contacting of toe spare 226, for example encircle part 206 with column piece 204 further away from each other by pulling forcibly, thereby cause the damage to installing 200.Therefore, wall section 227 helps to limit curved bar 208 away from the scope of the pivoting action of base 202.
When lever 214 from ring open position (such as Figure 21 to shown in Figure 26) pivot winding closed position when (such as Figure 14 to shown in Figure 20), the longitudinal axis that lug boss 242 also centers on the hole 220 of plate 212 pivots, 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 bars 208 to base 202, thereby curved bar 208 pivots (thereby arch part 206 is pivoted) are returned such as Figure 14 to ring closed position shown in Figure 20.
Can see, no matter lever 214 is encircling closed position or ring open position, or during pivoting action between these two positions, the vertical end opposite with lug boss 242 and toe spare 226 of lever 214 is always between two rings that formed by column piece 204 and arch part 206.Can also see, on the one hand, the pivot axis of lever 214 between lug boss 242 and toe spare 226, on the other hand, also between jut 242 and wall section 227.
Can see that also device 100 and device 200 are the structure that does not have spring.
