Abstract
A ring mechanism for retaining loose leaf pages has a housing and hinge plates supported by the housing for pivoting motion relative to the housing. Ring members are mounted on the hinge plates and are moveable between a closed position and an open position. An actuator is mounted on the housing for movement relative to the housing for causing pivoting motion of the hinge plates. A locking element releasably locks the closed ring members in a locked position and releases the closed ring members to move to the open position in an unlocked position. An intermediate connector operably connects the locking element to the actuator. The intermediate connector is deformable during movement of the actuator.
Description
Technical field

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 described 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 or other actuators 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.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, a 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, but described motion is the pivot by control handle or moves by other of suitable actuator and to realize.Therefore, the translational component that need only control handle be moved passes 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.

The carriage release lever 945 of this embodiment is operably connected to control handle 915 by intermediate connector 967.Intermediate connector 967 is shown and bends to wire elongated, essentially rectangular.First end of intermediate connector 967 opens wide and comprises that two free end 967a, free end 967a are assemblied in the respective openings 916 of upper arm 926 of control handle 915 and connects to form to pivot.Intermediate connector 967 second, closing end 967b narrows down and be assemblied in the elongated open 946 of first locking element 949 of carriage release lever 945 (Figure 73).In order to make intermediate connector 967 be connected in locking element 949, one of free end 967a of intermediate connector passes elongated open 946, and intermediate connector is handled up to closing end 967b and is positioned at elongated open.Intermediate connector 967 remains on the locking element 949, so that allow intermediate connector, still allow intermediate connector to move along linear direction forward simultaneously away from control handle with respect to locking element and carriage release lever towards tight element of control handle 915 zips and carriage release lever 945.Intermediate connector 967 also can pivot with respect to locking element 949 and carriage release lever 945, with slightly moving both vertically of the intermediate connector of regulating generation when control handle 915 pivots.
Shown in Figure 72, this mechanism 901 also comprises extension spring 985 (broadly, " biasing member "), and it is connected in articulated slab 927a at hook 987 places along the inward flange of one of articulated slab, 927b, and hook 988 places of stretching out downwards on carriage release lever are connected in carriage release lever 945.The bias voltage of spring 985 forces carriage release lever 945 to move towards locked position away from control handle 915.This also makes the narrow end 967b of intermediate connector 967 lean against on the outer end of the elongated open 946 on first locking element 949 of carriage release lever 945, helps control handle 915 is remained on stand up position (Figure 73).
The operation of the circular clip mechanism of this embodiment will be described now.Figure 70,72 and 73 show the mechanism 901 that is in closed and locked position, and wherein control handle 915 is in stand up position.For release circular clip mechanism 923a, 923b also opens ring component, and operating personnel are with control handle 915 outside and pivot downwards (clockwise direction shown in arrow among Figure 74).The lower lips 937 initial and articulated slab 927a of control handle 915, the lower surface of 927b spaced apart (Figure 73).This provides the time of drawing intermediate connector 967 for upper arm 926, this draws carriage release lever 945 simultaneously, make locking element 949 towards control handle 915 motion and lower lips 937 with before articulated slab engages with articulated slab 927a, the opening 929a on the 927b, 929b, the 929c alignment.Spring 985 extends and is tending towards carriage release lever 945 and locking element 949 are retracted locked position, makes locking element be positioned at articulated slab 927a, the 927b back.Shown in Figure 74,937 motions of the lower lips of control handle 915 and with articulated slab 927a, the lower surface engages of 927b (only showing an articulated slab 927a), and begin they are upwards pushed away.In case articulated slab 927a, 927b are by co-planar locations, the elastic force of housing 911 fully upwards pivots articulated slab and crosses locking element 949, ring component 923a, and 923b opens, shown in Figure 75.Spring 985 resilience slightly makes locking element 949 lean against articulated slab 927a, the opening 929a on the 927b, and 929b is on the inward flange of 929c.Still tensioning of spring 985, but locking element 949 remains on opening 929a, 929b in the 929c, and stops the stretching of spring.The elastic force of housing 911 prevents that locking element 949 from making articulated slab 927a under the effect of extension spring 985, and 927b makes camming movement downwards.
For closed hoop parts 923a, 923b and make mechanism 901 return locked position, operating personnel upwards and inwardly pivot control handle 915.The upper arm 926 of control handle 915 pushes away intermediate connector 967 forward.In the elongated open 946 of the narrow end 967b of intermediate connector on first locking element 949 of carriage release lever 945 from the rear end of elongated open towards the nose motion (Figure 76 B) of elongated open.Therefore, carriage release lever 945 is motionless at first.Along with control handle 915 continues to pivot, the last protuberance 938a motion of I shape structure 938 and with articulated slab 927a, the upper surface of 927b engages, and makes the articulated slab process co-planar locations that pivots downwards, opens ring component 923a, 923b.The inclination inward flange 955 of locking element 949 allows carriage release lever 945 along with articulated slab 927a, and 927b pivots downwards and motion slightly.As long as articulated slab 927a, 927b crosses the bottom surface of locking element 949, and extension spring 985 draws carriage release lever 945 and makes it and locking element get back to locked position, makes locking element be positioned at the articulated slab back.Carriage release lever 945 moves than short distance with respect to intermediate connector 967, contacts the outer end of the elongated open 946 on the carriage release lever 945 once more up to the narrow end 967b of intermediate connector.Then, carriage release lever 945 draws intermediate connector 967 and control handle 915, makes control handle return its stand up position (Figure 73).
In this embodiment, as ring component 923a, when 923b is closed, the lower lips 937 and the articulated slab 927a of control handle 915, the lower surface of 927b is spaced apart.Provide the space for lower lips 937 pivots like this, thus begin to make articulated slab upwards pivot before with locking element 949 from articulated slab 927a, the locked position of 927b back be pulled to articulated slab on opening 929a, 929b, the not lock position of 929c alignment.
And in this embodiment, first locking element 949 of intermediate connector 967 and carriage release lever 945 forms and makes locking element hold intermediate connector slidably, allows intermediate connector to move at linear direction along the longitudinal axis direction of carriage release lever with respect to locking element and carriage release lever.Intermediate connector 967 is positioned to respect to locking element 949 at first, makes the motion of opening of control handle 915 draw connector, makes carriage release lever 945 and locking element towards control handle motion and leave locked position simultaneously.Intermediate connector 967 can make the closing motion of control handle 915 push away intermediate connector, but not make the carriage release lever motion at first with respect to locking element 949 and carriage release lever 945 motions subsequently.Alternatively, intermediate connector 967 makes control handle 915 can at first make articulated slab 927a with respect to carriage release lever 945 motions, and 927b pivots with closed hoop parts 923a, 923b downwards.Spring 985 is pulled to locked position with carriage release lever 945 and locking element 949 subsequently, and this is pulled to stand up position with control handle 915 again.
Can expect that the control handle 915 of this embodiment is made by the rigid material such as metallic plate.Can use other materials within the scope of the invention.
Figure 77-83B shows the 11 embodiment of circular clip mechanism 1001, wherein use latch plate 1085 and torsion spring 1086 (broadly, " biasing member ") with carriage release lever 1045 and locking element 1049 to the locked position bias voltage and with control handle 1015 to the stand up position bias voltage.The extension spring of last embodiment omits in this embodiment.And in this embodiment, intermediate connector 1067 is connected in carriage release lever 1045, makes intermediate connector not slide with respect to carriage release lever.Alternatively, the upper arm 1026 of control handle 1015 is formed with elongated open 1016, make intermediate connector 1067 along the line the property direction in described opening with respect to control handle slide (Figure 83 B).
Shown in Figure 78, latch plate 1085 is the U-shapeds with the first arm 1085a and second arm 1085b.The second arm 1085b comprises and is used to hold the opening 1085c that latch plate is connected in the rivet 1092 of control handle 1015 inboards.Particularly, latch plate 1085 is connected in control handle 1015 between the upper arm 1026 of control handle and above lower lips 1037.The outer side engagement of torsion spring 1086 and control handle 1015.Especially, the main body of spring 1086 is extended in the outer periphery of control handle 1015.Spiral 1086a on the spring 1086 aligns with construction opening 1041 on the control handle 1015, makes the mount pin 1061 that connects control handle and housing 1011 also torsion spring is connected in control handle.The free end 1086b of torsion spring 1086 is arranged to the following side engagement with housing 1011, thereby limits their axis (shown in Figure 80) motions along clockwise direction around mount pin 1061.
In this variant, as ring component 1023a, 1023b is shown in Figure 77,79 and 80 when closed, and the free end 1067a of intermediate connector 1067 is positioned at the inner of the elongated open 1016 on the upper arm 1026 of control handle 1015.The first arm 1085a of latch plate 1085 engages with the free end 1067a of intermediate connector 1067, and forces them to and reach this position.When control handle 1015 pivots to open ring component 1023a, during 1023b, shown in the arrow among Figure 81, control handle pulls to control handle to intermediate connector 1067 and carriage release lever 1045 simultaneously, and locking element 1049 is moved to and articulated slab 1027a, opening 1029a on the 1027b, 1029b, the not lock position of 1029c alignment.Torsion spring 1086 tensioning and bendings along with the motion of control handle in that the outer periphery of control handle 1015 is extended are tending towards forcing control handle to get back to stand up position.If control handle 1015 is at ring component 1023a, 1023b opens and articulated slab 1027a, 1027b is released through before the co-planar locations, and torsion spring 1086 will push back stand up position to control handle, makes carriage release lever 1045 and locking element 1049 motions get back to locked position jointly.In case ring component 1023a, 1023b opens (Figure 82 and 83A), and locking element 1049 is positioned at articulated slab 1027a, opening 1029a on the 1027b, 1029b, in the 1029c, locking element stops the motion (elastic force of housing stops may be tending towards making the articulated slab camming movement power of the locking element of pivot downwards) of carriage release lever 1045 and intermediate connector 1067 by the elastic force of housing 1011.This also resists and is tending towards that control handle 1015 is made progress and the bias voltage of the inside torsion spring 1086 that pivots.
When control handle 1015 pivots with closed hoop parts 1023a, during 1023b, control handle upwards and inwardly swing, but intermediate connector 1067 keeps motionless (Figure 83 B).Locking element 1049 is positioned at the articulated slab 1027a that has upwards pivoted, the opening 1029a on the 1027b, and 1029b in the 1029c, and leans against on the leading edge of articulated slab opening, stop travelling forward of carriage release lever 1045 and intermediate connector 1067.Along with control handle 1015 continues to pivot, it slides in the elongated open 1016 of intermediate connector on the upper arm 1026 of control handle with respect to intermediate connector 1067 motions.This can find out in Figure 83 B.The first arm 1085a of latch plate 1085 is pushed to the second arm 1085b of latch plate by intermediate connector 1067, and the free end 1067a that latch plate leans against intermediate connector 1067 goes up and keeps motionless relatively.This makes latch plate 1085 deflections and tensioning.The last protuberance 1038a and the articulated slab 1027a of the I shape structure 1038 of control handle 1015,1027b engages, and they are pivoted towards co-planar locations.The inclination inward flange 1055 of locking element 1049 allows carriage release lever 1045 along with articulated slab 1027a, and 1027b pivots downwards and motion slightly.In case articulated slab 1027a, 1027b pivots and crosses locking element 1049, and control handle 1015 just moves to stand up position, and makes intermediate connector 1067, carriage release lever 1045 and locking element 1049 move to locked position.The latch plate 1085 of tensioning is pushed into the front end of the elongated open 1016 on the upper arm 1026 with intermediate connector 1067, guarantees that carriage release lever 1045 and locking element 1049 sufficient movements are to locked position.Approximately at the same time, extension spring 1086 upwards pushes away on control handle 1015, guarantees that it fully moves to stand up position.
Figure 85-90B shows the circular clip mechanism 1101 with the 12 embodiment.In this mechanism, the closing end that torsion spring 1186 (broadly, " biasing member ") is positioned to make spring is at pair of hinge plates 1127a, below the 1127b.The free end 1186b of spring 1186 curves inwardly, and passes elongated open 1116 assemblings on the upper arm 1126 of control handle 1115, and the free end 1167a that leans against intermediate connector 1167 goes up (in the outside, connector end).
When control handle 1115 pivots being opened into right ring component 1123a, during 1123b, control handle with intermediate connector 1167 pull to it (Figure 88).Control handle 1115 also is pulled away from the free end 1186b of spring 1186 closing end of spring, produces tension force in spring, and this tension force is tending towards forcing control handle 1115 to get back to stand up position.When control handle 1115 pivots with closed hoop parts 1123a, during 1123b, intermediate connector 1167 is at first by being positioned at articulated slab 1127a, the opening 1129a on the 1127b, and the locking element 1149 in the 1129b, 1129c keeps motionless basically.Along with control handle 1115 continues to pivot, control handle is with respect to intermediate connector 1167 motions.(Figure 90 B) slides in the rear end of the elongated open 1116 of the free end 1167a of intermediate connector 1167 on the upper arm 1126 of control handle 1115.Intermediate connector 1167 is pushed the free end 1186b of spring 1186 outer end of elongated open 1116 to, thereby makes tensioned.In case articulated slab 1127a, 1127b pivot and cross locking element 1149, spring 1186 just inwardly pushes away intermediate connector 1167 immediately, and carriage release lever 1145 and locking element 1149 are pushed into locked position.
Figure 91 shows the 13 embodiment of circular clip mechanism 1201, and this mechanism the 12 embodiment with Figure 85-90B basically is identical.In this embodiment, yet, the shape difference of control handle 1215, and make by plastic material.Control handle 1215 with basically with the same way as operating mechanism of describing with respect to the control handle 1115 of the circular clip mechanism 1101 of front 1201 with open and close ring component 1223a, 1223b.
