In the scope of the present invention.
Ring 113 is used to loose leaf paper to be maintained in notebook 103 on ring mechanism 101.The ring mechanism 101 shown in accompanying drawing has
There are three rings 113.However, the quantity of ring can change within the scope of this invention.The ring 113 shown in accompanying drawing is substantially mutually the same
And each is typically circle.As Fig. 1-6 shows, each ring 113 includes two ring elements 133（It is sometimes referred to as and specified
It is 133a and 133b representing the specific ring element in a pair of ring elements）.Ring element 133 is suitably by with circular cross section
The suitable material of shape（For example, steel）Conventional cylindrical bar formed.With being formed by different materials or have varying cross-section
Shape（For example, elliptical cross sectional shape）The annular mechanism for loose-leaf binder of ring element do not depart from the scope of the present invention.It is shown
Embodiment in ring element 133 be usually semicircle so that ring 113 have it is general round-shaped, but of the invention
In scope, ring can have non-circular shape.In addition, one in ring element can have different shape with another, such as in D-shaped
In the case of shape ring and other asymmetric rings.
At least one of ring element 133a of each ring 113 can closed relative to shell 111 and relative ring element 133b
Close position（Fig. 2）And open position（Fig. 4）Between move.In the ring mechanism 101 being shown in the drawings, two ring element 133a,
133b is each moved with substantially similar manner relative to shell 111, and with opening and close ring 113, but this is not practice
It is essential to the invention.For example, within the scope of this invention, one in the ring element of each ring can be fixed to shell.Closing
Close position（Fig. 2）, ring element 133 forms the ring of substantially continuous closure, to allow the loose leaf paper of the holding of ring 113 along ring from
Ring element moves on to another ring element.In open position（Fig. 4）, ring element 133 formed discontinuously, open ring, to add work
Page paper takes out loose leaf paper from ring 113.
Ring mechanism 101 includes two essentially identical articulated slabs 127 of support ring element 133.Articulated slab 127 is each typically
Elongated, flat and rectangular shaped, and the length of each is more slightly shorter than the length of shell 111.Articulated slab 127 is along in them
Longitudinal edge is with the interconnection that be arranged in parallel（As Fig. 3 and 5 shows）, so as to form the central hinge 145 with pivotal axis.This is with ability
Known usual manner is suitably carried out in domain.The outer longitudinal edge of articulated slab 127 is received within by the lower bending of shell 111
In the groove that edge 125 is formed, so as to be supported on the articulated slab pivoted in shell.As Fig. 6 shows that ring element 133a, 133b are each
It is arranged in articulated slab 127 in respective articulated slab 127 from general relative mode.Ring element 133 along shell 111 side
119 extend through respective opening 155 so that when ring 113 is closed, the free end of ring element is engaged with each other above shell.
Ring element 133 is rigidly connected to articulated slab 127 and is moved with articulated slab when articulated slab is pivoted.In the annular loose-leaf shown in accompanying drawing
In clamp mechanism 101, two ring elements 133 of each ring 113 are installed and cause the ring element 133 from the upper surface of articulated slab 127
Extend.However, one of them or more ring element is installed causes that they extend from the lower surface of articulated slab（For example, as jointly
It is disclosed in the US publication application No.20080008519 for possessing）Mechanism also within the scope of this invention.
Articulated slab 127 can be downward relative to shell 111 on central hinge 145 and be pivoted up, and is mounted above with
Ring element 133 move between the closed position and the open position.When articulated slab 127 is pivoted downwards（That is, central hinge 145 is moved
Move away from shell 111）When, ring element 133 is closed.When articulated slab 127 is pivoted up（That is, central hinge axle 145 is moved towards outer
Shell 111）When, ring element 133 is opened.When articulated slab is in co-planar locations, the combined width of articulated slab 127 is than under shell 111
Interval between curved edge 125 is wide.Therefore, when articulated slab 127 is pivoted through co-planar locations, articulated slab becomes shell 111
Shape simultaneously produces spring force in shell.When articulated slab 127 is in closing position, the shell spring force bias He of articulated slab 127
To remain closed, and when articulated slab is in open position, shell spring force biases articulated slab and ring to stay open ring 113.
User can relative to shell 111 move actuator 115 so that articulated slab 127 against from shell 111 being used to beat
Open and the spring force of close ring 113 is pivoted motion.Actuator 115 can wherein ring element 133 in closing position
One position（Fig. 9 and 10）The wherein second place of the ring element in open position（Figure 11）Between rotate.
In the embodiment described in which, actuator 115 is installed with lever mount 171（Fig. 6）On carried out relative to shell
Pivoting action between the opened and the closed positions, lever mount 171 is individually formed from shell 111 and is fixed to the shell
（For example, by one or more rivets or other suitable fasteners）.Lever mount 171 includes being arranged on shell plateau
In the plate 175 opened on end 121 of shell 111 on 117 tops.Lever mount 171 also has the opposite flank from plate 175 logical
The slit 179 crossed on the end 121 of shell extends into the arm 177 of shell 111.Actuator 115 is by extend through actuating
The trunnion 181 of device is pivotally attached to lever mount, and is kept by the arm of lever mount.Therefore, actuator 115 around with pin
181 pivotal axis for overlapping are pivoted.Lever mount 171 does not extend longitudinally beyond the opening end 121 of shell 111.Also, when ring closure
When, the relative small portion of only actuator 115 extends longitudinally beyond the opening end 121 of shell 111.It is outer including to be mounted directly to
Shell and without using single lever mount other install actuators mode without departing from the scope.
Referring now to Fig. 8-11, actuator 115 has main body 201 and the closure arm 203 extended from main body.Closure arm 203 sets
Put with the pivot articulated slab 127 when actuator moves on to closing position from open position and ring 113 is moved on to closing position.Actuator
115 also have and extend from main body 201 and sets with the pivot articulated slab 127 when actuator moves on to open position from closing position simultaneously
Ring 113 is moved on to the opening arms 205 of open position.As Figure 10 and 11 shows that closure arm 203 and opening arms 205 are formed and wherein connect
Receive articulated slab 127 end passage 207.Handle 211 extends from the main body 201 of actuator 115, with promote user open and
Mobile actuator between closing position.Within the scope of this invention, the handle of actuator can have many different shapes.
The end of articulated slab 127 is received in passage 207 so that closure arm 203 is above the end of articulated slab and opens
Arm 205 is below the end of articulated slab.Each articulated slab 127 has Longitudinal extending towards the relative of the opening end 121 of shell 111
Narrow finger 141（Fig. 6）.The respective width of finger 141 is narrower than respective articulated slab 127, and setting causes theirs
Interior longitudinal edge substantially aligns with the interior longitudinal edge and central hinge 145 of articulated slab.When actuator 115 is moved on to from closing position
During open position, opening arms 205 applies upward power to the finger 141 of articulated slab, and the upward power is upward central hinge 145
Pivot to open ring 113.Equally, when actuator moves on to closing position from open position, closure arm 203 applies downward force to finger
Shape part 141, the downward force downwards pivots central hinge 145 with close ring 113.
Except opening and closing ring 113 as described above, actuator 115 is also suitable for when actuator is in its opening and closing position
Locking member 221 in latched position when being moved between putting（Figure 10）And non-locked position（Figure 11）Between move, so as to open
With close ring 113.In latched position, locking member 221 prevents ring 113 by preventing the pivoting action of articulated slab 127 from closing

To open position.
As Fig. 7 and 8 shows that locking member 221 is three essentially identical lockings on the lock part 223 of mobile bar 225
Element（Each is designated as 221）In one, mobile bar 225 is in shell 111 on the plateau 117 of articulated slab 127 and shell
Between Longitudinal extending.The quantity of locking member can change without departing from the scope of the invention.Locking member 221 is along shifting
The lock part 223 of lever 225 is longitudinally spaced to open, and one of locking member is each adjacent to the lock part 223 of mobile bar
Longitudinal end, and a locking member is towards the centrally disposed of the lock part of mobile bar.Locking member 221 is from mobile bar 225
Lock part 223 is protruded towards articulated slab 127.As Fig. 7-11 shows, each locking member 221 includes flat 271, preceding hypotenuse
273 and rear extension 275.The hypotenuse 273 of locking member 221 engageable articulated slab 127 and contributes to downward pivot during closing
The central hinge 145 of turning hinge fishplate bar.In the embodiment described in which, locking member 221 for example by injection moulding process come with mobile bar
225 are integrally formed into a strip material.But, without departing from the scope of the invention, locking member can be with mobile bar point
Open form into and be connected to mobile bar.In addition, having for example block（For example, without hypotenuse）Locking member of different shapes in this hair
In bright scope.Mobile bar 225 and locking member 221 can be loosely referred to as " locking system ".
Otch 129（Fig. 3 and 6）Formed in each articulated slab 127 along the inward flange of plate.As best shown in Figure 3, each
Otch 129 in indivedual articulated slabs 127 is alignd, and five openings are formed with the central hinge 145 along interconnection articulated slab（Also referred to as
129）.Mounting post 151 is by an opening 129 in the articulated slab 127 at the opening end 121 of shell 111.Other openings
Three central hinge axles 145 along the articulated slab 127 near locking member 221 in 129 are axially arranged.Especially in fact, opening
129 are set so that when mobile bar 225 is in non-locked position（Fig. 5 and 11）When opening 129 registered with locking member 221, and so that
When mobile bar is in latched position（Fig. 3,9 and 10）When opening 129 with locking member non-registration.As Fig. 9 and 10 shows, work as mobile bar
225 in latched position, the upper surface of the articulated slab 127 on the edge of the flat 271 engagement opening 129 of locking member 221, from
And prevent articulated slab from being pivoted motion towards their open position.As shown, although the movement including locking member 221
The part of bar 225 can extend across the opening 129 in articulated slab 127, but mobile bar is between articulated slab 127 and shell 111
The continuous Longitudinal extending between the opposite longitudinal end of mobile bar in space.
The intermediate connector part 227 of mobile bar 225（Fig. 6 and 7）The lock part 223 of mobile bar is connected to actuator
115.The intermediate connector 227 of mobile bar 225 is by permission connector part relative to the hinge 229 that lock part moves pivotally
（For example, hinges）Lock part 223 is suitably connected to, to promote can be by actuator 115 to be rotated including certain
Mode is converted into the linear movement of the lock part of mobile bar come the motion of the connector part for driving.For example because hinge builds
Into one section of the thickness mobile bar smaller than connector part 227, hinge 229 suitably has the connector portion than mobile bar 225
Divide 227 big flexibilities.Recognize, in wide in range scope of the invention, it is not necessary to the lock part of mobile bar and connecting portion
/ chain connection.
Referring to Fig. 6,10 and 11, the end of the connector part 227 of the mobile bar 225 relative with hinge 229 is in shell
Open end 121.The end of connector part 227 has along shell 111 towards the arm 231 for opening the Longitudinal extending of end 121 and in shifting
The end of lever 225 and the cross-bar 233 for extending between the arms.Cross-bar 233 is captured by actuator 115 so that actuator exists
The movement of mobile generation between open and closed positions in the cross-bar 233 of the end of mobile bar 225.
Referring to Fig. 8, there are the slit or recess 255 that can wherein capture in the cross-bar 233 of the end of mobile bar 225.Institute
State in embodiment, recess 255 is between closure arm 203 and handle 211.When the cross-bar 233 of mobile bar 225 is by actuator
115 in recess 255 when capturing, and cross-bar extends to the opposite side of actuator through recess from the side of actuator.Recess 255
Part limited with conforming generally to the concave surface 265 of the shape of cross-bar 233 by shaping, with promote cross-bar during opening against
Concave surface.Another part of recess is limited by shaping with conforming generally to the concave surface 251 of the shape of cross-bar 233, to promote cross-bar
Against the surface during closing.
Mobile bar 225 and actuator 115 are adjusted and cause that cross-bar 233 can be by along one during the assembling of ring mechanism 101
As perpendicular to cross-bar longitudinal axis direction（For example, as indicated by arrow in Fig. 8, it is general downward）Moved relative to actuator
Cross-bar and rapidly enter recess 255.This is probably favourable, because it promotes to use mobile bar 225, wherein cross-bar 233
One piece is integrally formed into the remainder of connector part 227.This is also likely to be favourable, because need not be various assemblies
With other component Accurate aligns and accurately insert the component, if the assembling of mobile bar and actuator needs pin or other are thin
Long structure is longitudinally inserted into the opening with the structure that will be inserted about same size, then be exactly that situation mentioned above.
Which simplify the assembling of ring mechanism 101.
