Abstract
A ring mechanism for retaining loose-leaf pages comprises a housing and ring members for holding loose-leaf pages that are moveable relative to the housing between an open and closed position. An actuation system moves the ring members and includes hinge plates pivotally mounted on the housing and a lever actuating pivoting movement of the hinge plates in at least one direction (e.g., moving the hinge plates and ring members to the open position). The lever is connected to a travel bar that moves lengthwise of the housing between a position blocking pivoting movement of the hinge plates and a position allowing pivoting movement of the hinge plates. At least one of the lever and the hinge plates deforms when the lever moves to delay pivoting movement of the hinge plates so that the lever may move the travel bar so that it does not block movement of the hinge plates.
Description
Technical field
The utility model relates to the circular clip mechanism that is used to keep loose leaf paper, relates in particular to be used for the open and close ring component and to be used for the improvement mechanism that the ring component with closure locks together.
Background technology
Circular clip mechanism will remain in file or the notebook such as the loose leaf paper of perforated paper.It has a plurality of ring components that are used to keep page.Ring component can be opened selectively to increase or taking-up page or closed to keep page and page is moved along ring component.Ring component is installed on two adjacent articulated slabs, and articulated slab combines around pivot axis.Thin-long casing is supported on articulated slab in the housing and with articulated slab loosely and keeps together, so that articulated slab can pivot with respect to housing.
When articulated slab when co-planar locations (180 °), deformation-free housing is narrower slightly than the articulated slab of combination.For articulated slab is pivoted by this position, they make the elastic shell distortion and produce elastic force in housings, impel articulated slab to pivot and leave co-planar locations to open or the closed hoop parts.Like this, when ring component was closed, elastic force hindered articulated slab and moves and ring component is clipped together.Similarly, when ring component was opened, elastic force made them keep separating.The operator can overcome elastic force by manually drawing back ring component or they being pushed away together.Also can control handle be set, be used for shift(ing) ring parts between the open and close position in the housing one or both ends.A shortcoming of these known circular clip mechanisms is that when ring component was closed, they can not lock together reliably.If this mechanism unexpectedly drops, ring component may by mistake be opened.
Some circular clip mechanisms have been modified to comprise locking mechanism, stop articulated slab to pivot with convenient ring component when closed.If circular clip mechanism unexpectedly drops, barrier structure is locked together the closed hoop parts reliably, prevents that them from by mistake opening.Barrier structure also makes housing elastic force reduce, because do not need strong elastic that the closed hoop parts are clipped together.Therefore, compare, only need less operating physical force to come the ring component of these mechanisms of open and close with the traditional endless clamp mechanism.
Some of these circular clip mechanisms are included in locking mechanism on the control slide block that is connected to control handle.Control handle moves control slide block (with its locking mechanism) to stop the articulated slab pivoting action or to allow its pivoting action.The shortcoming of these circular clip mechanisms is, the operator must mobile reliably control handle after the closed hoop parts, stops articulated slab and pins the closed hoop parts with the positioning and locking structure.May not cause articulated slab unexpectedly to pivot and open ring component if so do, especially when mechanism unexpectedly drops.
When ring component was closed, some locking circular clip mechanisms used spring locking mechanism to be moved to the position that stops articulated slab.Example is presented at total U.S. Patent application Nos.10/870, among 801 (Chenget al.), 10/905,606 (Cheng), 11/027,550 (Cheng).These circular clip mechanisms adopt independent spring to help lock circular clip mechanism.
Therefore, need a kind of so simple circular clip mechanism, it can be easy to ring component is locked together when circular clip mechanism is closed, and does not need other spring element.
The utility model content
A kind of circular clip mechanism that is used to keep loose leaf paper comprises housing and is used to keep a plurality of rings of loose leaf paper.Each ring comprises first ring component and second ring component.At least one ring component can move between closing position and open position with respect to housing and another ring component.In closing position, two ring components form continuous substantially closed hoop, move to another ring component along ring from a ring component with the loose leaf paper that allows to be held by environmental protection.At open position, two ring components form the discontinuous ring of opening, to increase or to take out loose leaf paper from ring.The actuating system of this mechanism comprises by housings support with respect to first and second articulated slabs of described housing pivoting action and be installed in the actuator that causes the articulated slab pivoting action on the housing to move with respect to housing.At least one ring component is installed on first articulated slab so that move between open position and closing position.Actuating system is suitable for distortion when actuator moves, to postpone the pivoting action that moves the articulated slab that causes owing to actuator.
On the other hand, circular clip mechanism comprise housing and by housings support with articulated slab with respect to described housing pivoting action.The loose leaf paper in the mechanism is held in environmental protection.Each ring comprises first ring component and second ring component.First ring component is installed on first articulated slab, with along with this articulated slab moves between closing position and open position with respect to second ring component.In closing position, two ring components form continuous substantially closed hoop, move to another ring component along ring from a ring component with the loose leaf paper that allows to be held by environmental protection.At open position, two ring components form the discontinuous ring of opening, to increase or to take out loose leaf paper from ring.Mechanism also comprises and is installed in the actuator to move with respect to housing on the housing.Actuator is suitable for changing from body contour in the process of shift(ing) ring parts between closing position and open position at the operation circular clip mechanism.

Describe the circular clip mechanism 1 of assembling form now with reference to Fig. 4-7, wherein circular clip mechanism is shown as that ring component 23a, 23b are in the close position and control handle 15 is in stand up position.Control handle 15 is installed in first end (Fig. 4-6) that opens wide of housing 11 pivotally at hold-down arm 19 places of housing.Joint pin 59 on each hold-down arm 19 aligns with the passage 41 of control handle 15.Joint pin 59 passes the opening 57 and the passage 41 of alignment, so that pivotally control handle is installed on the housing 11.Can imagine that hold-down arm 19 is one with housing 11, but hold-down arm 19 can form and be installed on the housing with housing 11 dividually, and not break away from the utility model scope.
As shown in Figure 6, carriage release lever 45 is arranged on flat top portion 17 back that are positioned at housing in the housing 11.It along housing 11 longitudinal extensions and with the longitudinal axes L A of housing directed (Fig. 2) abreast substantially, make locking element 49 away from housing.Pass two rivet openings 63 (only show among Fig. 6, also can referring to Fig. 2) alignment of two elongated open 61 (only show among Fig. 6, also can referring to Fig. 2) with the housing flat top portion 17 of carriage release lever 45.The corresponding elongated open 61 that fluting rivet 65 (only show among Fig. 6, also can referring to Fig. 2) is fixed on the housing 11 and passes carriage release lever 45 at rivet opening 63 places is so that vertically be supported on carriage release lever in the housing.Carriage release lever 45 is contained in the groove of rivet 65, make it can along housing 11 axially with respect to the rivet sliding translation.
Shown in Fig. 6 and 7, carriage release lever 45 is operably connected to control handle 15 by intermediate connector 67.In the embodiment shown, intermediate connector 67 is the wires (Fig. 2) that bend to elongated rectangle substantially.Intermediate connector 67 can have other shape or be formed by other material, does not also break away from the utility model scope.First end of intermediate connector 67 be open wide and comprise among opening 71a, the 71b on the body 35 that is contained in control handle 15 (among Fig. 3 only opening 71b as seen) to form two free end 69a, 69b that pivot and connect.Closure second end of intermediate connector 67 narrows down and comprises curved end 73 (Fig. 2) in the mounting groove 47 that is contained in carriage release lever 45.Curved end 73 is fixed to intermediate connector 67 on the carriage release lever 45 at mounting groove 47 places, to promote or the pulling carriage release lever.Curved end 73 allows intermediate connector 67 to pivot with respect to carriage release lever 45, to adapt to little vertical the moving of the intermediate connector that occurs when control handle 15 pivots.There is not the circular clip mechanism of intermediate connector (that is, wherein carriage release lever is directly connected to control handle pivotally) not break away from the utility model scope yet.
As illustrated in Figures 5 and 6, articulated slab 27a, 27b interconnect along their interior longitudinal edge with being arranged in parallel, form to have the center hinge 75 of pivot axis.This realizes in the prior art manner known.As described below, articulated slab 27a, 27b can pivot up and down around hinge 75.In two articulated slab 27a, 27b four otch 29a-d (Fig. 2) alignment on each, on interconnective articulated slab, to form four opening 29a-29d (Fig. 5).Housing 11 is supported on interconnective articulated slab 27a, 27b and is positioned at carriage release lever 45 belows in the housing.The outer longitudinal edge of articulated slab 27a, 27b is assemblied in the back on the bending base 21 of housing 11 loosely, so that they can move in the bending base when articulated slab pivots.As shown in Figure 7, the fingers 31 of articulated slab 27a, 27b (only having shown an articulated slab 27a) extends in the C shape space of the control handle 15 between the upper lip 35a of tongue 37 and body 35, makes the lower surface of articulated slab cooperate with control handle protrusion 43.
As shown in Figure 5, shown in two erection column 79a, 79b are fixed on the circular clip mechanism 1, with circular clip mechanism with known manner for example be installed in notebook 3 (for example, Fig. 1) on. Erection column 79a, 79b are installed to (Fig. 2) on the housing 11 at erection column opening 81a, the 81b place of the flat top portion 17 that is positioned at the housing longitudinal end.The first erection column 79a (Fig. 5 right side) passes intermediate connector 67 and passes the erection column opening 29d of interconnective articulated slab 27a, 27b.
The following operation of describing circular clip mechanism 1 with reference to Fig. 4-13.As known to, articulated slab 27a, 27b pivot up and down with respect to housing 11 and move ring component 23a, 23b mounted thereto between closing position (Fig. 1,4-10) and open positions (Figure 11-13).Wideer slightly than housing when co-planar locations (180 °) as articulated slab 27a, 27b, pivot by co-planar locations in order to make articulated slab, they make housing distortion and produce little elastic force in housings.Housing elastic force bias voltage articulated slab 27a, 27b leave co-planar locations to pivot up or down.When articulated slab 27a, 27b pivot (that is, hinge 75 moves apart housing 11 (for example Fig. 5)) downwards, ring component 23a, 23b closure.When articulated slab 27a, 27b upwards pivoted (that is, hinge 75 is shifted to housing 11 (for example Figure 12)), ring component 23a, 23b opened.
In Fig. 4-7, circular clip mechanism 1 is in closed and locked position. Articulated slab 27a, 27b are made ring component 23a, the 23b of each ring 13 together form the continuous circular ring that can keep loose leaf paper by hinged away from housing 11 downwards.Control handle 15 is vertical with respect to housing 11 and is in first slack position (in Fig. 3 control handle also show be in this position), control handle protrusion 43 is cooperated with the lower surface of articulated slab 27a, 27b.The locking element 49 of carriage release lever 45 is positioned at articulated slab 27a, 27b top and aligns with hinge 75 substantially, and their narrow flat bottom 53 is contacted with the upper surface of articulated slab.As shown in Figure 5, the contiguous corresponding locking element opening 29a-29c of locking element 49, but substantially not with these register.(by fluting rivet 65 vertical support) carriage release lever 45 and locking element 49 overcome together and are tending towards making articulated slab 27a, the 27b upwards pivot with any power (that is the closed ring component of their lockings) of opening ring component 23a, 23b.
For release circular clip mechanism 1 and open ring component 23a, 23b, the operator apply force to the grip part 33 of control handle 15 and make its pivot counterclockwise (shown in Fig. 4,6 and 7).Shown in Fig. 8-10, the grip part 33 and the body 35 of control handle 15 move with respect to tongue 37, and tongue 37 keeps static by articulated slab 27a, 27b under the elastic force effect of housing 11.Intermediate connector 67 moves simultaneously along with body 35 and control handle 15 is delivered to carriage release lever 45 around the pivoting action of erection column 79a.Carriage release lever 45 slides to control handle 15 and locking element 49 is moved to corresponding locking element opening 29a-29c positions aligning with articulated slab 27a, 27b.When open channels 41 is closed, 39 bendings of bridge portion and stretching between body 35 and the tongue 37, body moves to and contacts (Figure 10) with tongue.If articulated slab 27a, 27b upwards pivot by before the co-planar locations (promptly, before ring component 23a, 23b open) release control handle 15, tension force in the bridge portion 39 makes grip part 33 and body 35 return (and pushing away) automatically to the upright position, and carriage release lever 45 and locking element 49 are moved to locked position.
Closed now control handle passage 41 no longer stops tongue 37 to pivot mobile with grip part 33 and body 35.The opening continuously of control handle 15 moved and to be caused body 35 tongue 37 that pivots together.Control handle protrusion 43 causes interconnective articulated slab 27a, 27b upwards to pivot on the locking element 49 at locking element opening 29a-29c place and with respect to the 79a at erection column opening 29d place.In case articulated slab 27a, 27b are by co-planar locations, housing elastic force upwards promotes them, opens ring component 23a, 23b (Figure 11-13).Control handle 15 can be released.Tension force in the bridge portion 39 is return (and promote) grip part 33 and body 35 away from tongue 37, and tongue 37 is static near articulated slab 27a, 27b maintenance by the control handle protrusion 43 that cooperates with the articulated slab lower surface.Passage 41 is opened and carriage release lever 45 moves apart control handle 15 a little.Control handle is lax once more, is in second slack position (Fig. 3) identical substantially with first slack position, and locking element 49 is among the corresponding articulated slab locking element opening 29a-29c, and is not tending towards any power that they are moved with respect to housing 11.
Turn back to locked position for closed hoop parts 23a, 23b and with mechanism 1, the operator manually shifts free end 25a, the 25b of ring component 23a, 23b together onto.Articulated slab 27a, the 27b control handle tongue 37 (shown in Figure 11 and 13) that pivots downwards and turn clockwise.Tongue 37 moves grip part 33 and body 35, makes locking element 49 near the protuberance at the edge of the locking element opening 29a-29c of articulated slab 27a, 27b 83 in place (protuberance be tilt to help locking element 49 to shift out opening).Tongue 37 is subsequently with respect to keeping static grip part 33 and body 35 to move by the locking element 49 near protuberance 83.Control handle passage 41 closures (and control handle bridge portion 39 bending) are pivoted to articulated slab 27a, 27b and by co-planar locations and through the narrow bottom 53 of locking element 49.As articulated slab 27a, when 27b moves down, the angled sides 55a of locking element 49 makes locking element move apart control handle 15 rapidly and shifts out from respective openings 29a-29c.This makes that control handle 15 is along with tongue 37 pivots a little when control handle passage 41 closures.But the angled sides of locking element for operation not necessarily.
In case articulated slab 27a, 27b leave the bottom 53 of locking element 49, tongue 37 promotes grip part 33 and body 35 arrives the upright position, and carriage release lever 45 and locking element move to locked position.Ring component 23a, the 23b of circular clip mechanism 1 can be by the improvement control handle closure that cooperates and make their to pivot downwards with articulated slab 27a, 27b, and does not break away from the utility model scope.
Obviously, the flexible grip part 33 of control handle 15 and the body 35 of making of control handle bridge portion 39 moves with respect to tongue 37.This moves control handle 15 between slack position (Fig. 3-7 and 11-13) and distortion (broadly, " change profile ") position (Fig. 8-10).The deformation position of control handle 15 is unsettled centre positions, and its jackshaft portion 39 is stretched so that always mobile grip part 33, body 35 and tongue 37 arrive slack position (that is, changing the control handle profile).
When control handle 15 pivots when opening ring component 23a, 23b, carriage release lever 45 and locking element upwards move before pivot-hinge fishplate bar 27a, the 27b immediately and at tongue 37 and protrusion 43.This sky that is caused by open channels 41 is moving to make locking element 49 move to the locking element opening 29a-29c of articulated slab 27a, 27b before articulated slab 27a, 27b pivot to align.They do not influence the required pivoting action of articulated slab 27a, 27b.Move to after corresponding locking element opening 29a-29c aligns at locking element 49, passage 41 closures, grip part 33, body 35 and tongue 37 pivot together with articulated slab 27a, the 27b of moving up.
Except when ring component 23a, 23b open and control handle 15 when lax, locking element 49 and carriage release lever 45 are not subjected to being tending towards they are moved to the power of locked position.Therefore, during when operator's loading or from ring component 23a, 23b taking-up page, can not be tending towards by mistake closed under the effect of control handle 15, locking element 49 or carriage release lever 45 for the ring component 23a, the 23b that open.
Similarly, as ring component 23a, when 23b is moved to closing position, control handle passage 41 pivoted articulated slab 27a, 27b downwards on locking element 49 before the grip part 33 of control handle 15 and body 35 are shifted carriage release lever 45 and locking element 49 onto locked position.Here, continuous cooperation the between moving (by control handle protrusion 43) the retentive control tang portion 37 of this sky that causes by open channels 41 and articulated slab 27a, the 27b, and (for example do not have danger that mechanism blocks at open position, if because the edge of the locking element opening 29a-29c of locking element 49 wedging articulated slabs makes the control handle tongue not move down along with articulated slab, stop articulated slab further to pivot downwards).(by control handle protrusion 43) guarantees continuous the cooperation between control handle tongue 37 and articulated slab 27a, 27b lower surface, when articulated slab 27a, 27b are pivoted (and ring component 23a, 23b are closed) downwards, the body 35 of control handle 15 and grip part 33 fully move to their upright position, and carriage release lever 45 and locking element 49 are fully moved to locked position.
Like this, when ring component 23a, 23b were closed, circular clip mechanism 1 kept loose leaf paper effectively, and prevents that reliably ring component 23a, 23b from by mistake opening.When ring component 23a, 23b were closed, control handle 15 was positioned at locked position with carriage release lever 45 and its locking element 49, had eliminated manual mobile control handle 15 with the necessity of retaining mechanism 1 reliably.Comprise that the circular clip mechanism 1 of control handle 15 does not need to carry out the additional bias element of locking operation (for example, spring), and do not need the special part that forms to hold this biased element.
Figure 14-16 shows second embodiment of circular clip mechanism of the present utility model, and the mechanism of this embodiment is with label 101 expressions.The mechanism 101 of this embodiment is similar substantially with the mechanism 1 of above-mentioned first embodiment that describes with reference to Fig. 1-13, adopts identical label to add " 100 " expression with the first embodiment mechanism 1 corresponding parts in the mechanism 101 of second embodiment.But in circular clip mechanism 101, control handle 115 has low profile, because it comprises the grip part 133 of flat.Control handle 115 is installed in (Figure 14 and 16) on the housing 111 as the description of above-mentioned circular clip mechanism 1 for Fig. 1-13, smooth grip part 133 be positioned to align substantially with the flat top portion of housing 117 (that is, coplane) substantially.In others, comprise operation, circular clip mechanism 101 is identical with the circular clip mechanism 1 of Fig. 1-13.
Figure 17-21 shows the 3rd embodiment of circular clip mechanism of the present utility model, and the mechanism of this embodiment is with label 201 expressions.Adopt identical label to add " 200 " expression with the first embodiment mechanism, the 1 corresponding parts of Fig. 1-13 in the mechanism 201 of second embodiment.The mechanism 201 of this embodiment is similar substantially with the mechanism 1 of above-mentioned first embodiment that describes with reference to Fig. 1-13, except control handle 215 does not form bridge portion and the passage between body 235 and tongue 237 not.Other element of circular clip mechanism 201 and the assembling of element are identical substantially with the circular clip mechanism 1 of Fig. 1-13.
The operation of circular clip mechanism 201 is described hereinafter with reference to the local figure of the amplification of Figure 19-21.In Figure 19, circular clip mechanism 201 is in closed and locked position (being similar to the closing position of the circular clip mechanism 1 of Fig. 1-13).For release circular clip mechanism 201 and open ring component 223a, 223b, operator's control handle 215 (seeing it is counterclockwise) that outwards and downwards pivots from Figure 19.Control handle body 235 pulls to control handle 215 with carriage release lever 245 and locking element 249, and control handle protrusion 243 upwards pushes away simultaneously on articulated slab 227a, 227b and (only shown articulated slab 227a).But still the locking element 249 that is positioned at articulated slab 227a, 227b back stops that they move up.When control handle 215 continues to pivot, articulated slab 227a, the 227b (Figure 20) of the contiguous fingers 231 of control handle protrusion 243 bendings (and tensioning).Align in case locking element 249 (only showing) moves to the locking element opening 229a-229c (only showing opening 229c) of articulated slab 227a, 227b, the articulated slab of tensioning upwards pivots by co-planar locations (Figure 21) to open ring component 223a, 223b (not shown) immediately.If control handle 215 was released before articulated slab pivots by co-planar locations, the articulated slab of tensioning will push away downwards on control handle protrusion 243 and make control handle 215 get back to the upright position, and carriage release lever 245 and locking element 249 are moved to locked position.Tension force among articulated slab 227a, the 227b is eliminated and control handle 215 can be released.The protrusion 243 of tongue 237 keeps cooperating with the lower surface of articulated slab 227a, 227b, and the elastic force of housing 211 keeps articulated slab 227a, 227b upwards hinged.Locking element 249 is among the corresponding articulated slab locking element otch opening 29a-29c, and is not tending towards they are moved to any power of locked position.
As in the circular clip mechanism 1 of Fig. 1-13, turn back to locked position (Figure 19) for ring component 223a, the 223b of closed annular clamp mechanism 201 and with mechanism, the operator manually shifts free end 225a, the 225b of ring component together onto.In this embodiment, articulated slab 227a, 227b pivot downwards and cause control handle protrusion 243 and tongue 237 turn clockwise (from what Figure 21 saw).Tongue 237 promotes grip part 233 and body 235, makes the protuberance 283 in place (this cooperation for operation not necessarily) of locking element 249 near the edge of the locking element opening 229a-229c of articulated slab 227a, 227b.Locking element 249 stops moving of control handle 215 immediately, thereby stops moving down of articulated slab 227a, 227b, causes near articulated slab 227a, 227b bending a little their fingers 131.Articulated slab 227a, 227b are bent downwardly, and control handle 215 is static with fingers 231 relative maintenances simultaneously.When articulated slab 227a, 227b were crooked, the angled sides 255a of locking element 249 made locking element move on a small quantity away from control handle 215, makes control handle pivot a little.In case articulated slab 227a, 227b leave the narrow bottom 253 of locking element 249, the tension force in the articulated slab of bending is pivoted to its upright position with control handle 215 immediately, shifts carriage release lever 245 and locking element 249 onto locked position.
In this circular clip mechanism 201, the uniqueness between control handle 215, articulated slab 227a, 227b and locking element 249 cooperates operates this mechanism between closed and locked position and open position.When opening ring component 223a, 223b, articulated slab 227a, 227b upwards bend simply so that control handle 215 pivots, and locking element 249 are moved to the locking element opening 229a-229c of articulated slab align.Control handle 215 with from the tension force of articulated slab 227a, the 227b of bending and the elastic force of housing 211 articulated slab is pivoted on locking element 249, to open ring component 223a, 223b.When closed hoop parts 223a, 223b, articulated slab 227a, 227b bend once more so that articulated slab pivots downwards on locking element 249 (the angled sides 255a of locking element 249 also helps this operation, but for this operation not necessarily).
The element of the circular clip mechanism of described here and illustrated embodiment is by making such as the suitable rigid material of metal (for example steel).But by nonmetallic materials particularly the plastics mechanism of making do not break away from scope of the present utility model yet.
When introducing the element of the utility model or most preferred embodiment, article " ", " being somebody's turn to do " and " described " means that one or more elements are arranged.Term " comprises " that " comprising " and " having " is meant to comprise and mean also have other parts except components listed.In addition, this is employed " on ", the distortion of D score and these terms just for convenience, and need not the concrete arbitrarily location of element.
Because above-mentioned various distortion all can be made not breaking away under the utility model scope, therefore above literal and all the elements shown in the drawings all should regard a kind of as and schematically and not should regard a kind of restriction as.
