In accompanying drawing 1-5, express the ring binder 10 that is used to bind ring book, it comprises pedestal 12, along pedestal be interval with three ring-type elements 14 (shown in the Figure 4 and 5 one of them), and the unlatching blocking mechanism 20 (accompanying drawing only illustrates an end) that is arranged in the pedestal two ends.

Pedestal 12 comprises top rigid structural member 24, the upper junction member has curved cross sectional profile, supporting hinged lower junction member 30 between its two flangings 26, lower junction member 30 comprises two bearing tracks 32, bearing track 32 can be mutually along the longitudinal axis revolution of attachment means 10.

Ring-type element 14 be installed in can rotating lower junction member 30 on, particularly, a circular element in each ring-type element (being element 14a) is installed on the bearing track 32, and another circular element (not shown) in each ring-type element is installed in (also not shown) on another bearing track.

For ring binder 10 is fixed on file or the ware, also on upper junction member 24, be provided with fixture 34 simultaneously.

Owing to be arranged on the action of the unlatching blocking mechanism 20 of each end of bearing track, two bearing tracks 32 can move (i.e. revolution) mutually between lower position and upper position.

For opener 20 is positioned between the structural member of upper and lower, opener 20 hingedly is supported on an end of upper junction member 24, and is meshed with an end of lower junction member 30.Particularly, for with respect to upper junction member 24 engagement and fixing lower junction member 30, and between lower junction member 30 and upper junction member 24, hingedly support opener 20, each side at opener 20 is provided with two

ridges

33 and 35, they one be positioned at another the top (shown in Figure 4 and 5), they are inclusive in curved end 37 inside of the side 26 of upper junction member 24, and

ridge

33 and 35 outwards is positioned at the top and the bottom of the outboard end 39 of bearing track 32 respectively.In addition, opener 20 is supported between the structural member of upper and lower, so that gyration, yet but be to be fixedly mounted between the structural member (promptly not have transverse movement etc.) aspect other.

For the ease of the ground of automation between upper and lower

structural member

24 and 30 opener 20 is installed, sagging tabs and analog do not form obstacle to whole outer ends of upper junction member 24 basically.So, opener 20 is installed on the ring binder, only need directly opener 20 is put between upper and lower

structural member

24 and 30, then the curved end 37 of each side 26 of crooked (extruding) upper junction member together.Because sagging tabs and congener do not form obstacle to the outer end of upper junction member 24, so just obtained to save the advantage of material.The material of being saved surpasses known devices 2-4% in this respect.

Ring binder has a locked position (as shown in Figure 1) and two lockset position of coupler (shown in Fig. 2 and 3).

In order to enter above-mentioned position, on the opener 20 of each end, be provided with first projection 36, ridge 38 co-operatings of top rigid structural member 24 lower surfaces of projection 36 and pedestal.

Ring binder has two closing positions (as illustrated in fig. 1 and 2) and an enable possition.

In order to enter above-mentioned position, on opener 20, be provided with second projection 40, this projection 40 with two can rotating bearing track 32 lower surface be meshed.

Particularly, finish locking action, so that at closed and locked position (as shown in Figure 1) by projection 36 and ridge 38 co-operatings.Projection 36 is positioned at ridge 38 1 sides; And at lockset position of coupler, projection 36 is positioned the opposite side of ridge 38.At closure and locked position, projection 40 does not contact with the lower surface of bearing track 32, so ring-type element 14 is in complete closing position.But at closure and lockset position of coupler, projection 40 contacts with the lower surface of bearing track 32, and makes bearing track 32 move up a little (but do not make bearing track upwards revolution).

Open ring-type element 14, it obtains by outwards fully promoting opener 20, this makes projection 40 be meshed with the lower surface of bearing track 32, therefore upwards upset of these tracks (promptly clamping revolution), at this point ring-type element 14 complete openings,, opens and lockset position of coupler (as shown in Figure 3) ring binder 10 so being in.

In addition,, make it directly enter closure and locked position, perhaps enter closure and locked position, on unlatching/blocking mechanism 20, be provided with the 3rd projection 42 from unlatching and lockset position of coupler from unlatching and lockset position of coupler for closed annular element 14.Particularly, the 3rd projection 42 has to overhanging ridge 44, and the upper surface engagement of itself and bearing track 32 so that apply active force to track, moves down track and to turning down.

In Fig. 6～10, the ring binder 50 of expression is similar to the attachment means 10 shown in Fig. 1-5.The main difference point of these two kinds of ring binders is that the structure of unlatching/blocking mechanism 20 is inequality.

For opener 20 is positioned between the structural member of upper and lower, hingedly be supported on each end of top rigid structural member 24 at the opener 20 of the ring binder 50 shown in Fig. 6～10, and with each end engagement of rotating lower junction member 30.Particularly, for ridge 52 being meshed between lower junction member 30 and upper junction member 24 and locating, the ridge 52 (as shown in Figures 9 and 10) that is arranged on opener 20 each side is inclusive in the pressed end 37 interior (seeing the dotted line among Fig. 9) of the flanging 26 of superstructure 24, and ridge 52 outwards is arranged on the outer side edges 39 of bearing track 32.And opener 20 is supported between the structural member of upper and lower, so that opener 20 gyrations, yet but be that fixed in position (does not promptly have transverse movement etc.) in other respects between the structural member of upper and lower.

For the ease of automation ground opener 20 is installed in 24 of upper and lower structural members, in fact sagging tabs and congener do not constitute obstacle to whole outer ends of upper junction member 24.So, opener 20 is installed on the ring binder, only need directly opener is put between upper and lower

structural member

24 and 30, then the folded end 37 of each flanging 26 of crooked (extruding) upper junction member together.Because sagging tabs and congener do not form obstacle to the outer end of upper junction member 24, this has just obtained to save the advantage of material.In this respect, the material of being saved surpasses known devices 2-4%.

Similar to ring binder 10 shown in Figure 1, ring binder 50 has two closing positions (shown in Fig. 6 and 7) and an enable possition.

In order to enter above-mentioned position, each end at opener 20 is provided with two different geared assemblies, promptly first geared assembly is a support 54, itself and lower surface collaborative work that can rotating bearing track 32: and second geared assembly is a projection 56, itself and upper surface engagement that can rotating bearing track 32.

Particularly, as shown in Figure 7,, when lever 20 further outwards moves, cause that projection 54 upwards promotes the lower surface of bearing track, enters enable possition as shown in Figure 8 at the lower surface of closing position support 54 engagement bearing tracks 32.Then, open mechanism so that during the closed hoop element when inwardly drawing back, projection 56 applies effect in enable possition shown in Figure 8 to the top of bearing track 32, and bearing track is pushed Fig. 6 or closing position shown in Figure 7 downwards.

Similar to the attachment means 10 shown in Fig. 1, ring binder 50 also has a locked position (as shown in Figure 6) and two lockset position of coupler (shown in Fig. 7 and 8).Particularly, blocking mechanism 20 is " b " tee section haply.The end face of the bottom 58 of " b " tee section is provided with several planes 60, and these planes can apply active force to the lower surface of top structural member 24.At lockset position of coupler shown in Figure 7, these end faces 60 disengage with the lower surface of upper junction member 24.But in case move inward retaining mechanism 20, end face 60 promptly contacts with the upper junction member, and their contact generation when being preferably in the projection 56 of bottom on 58 and contacting with the upper surface of bearing track 32.

Particularly, for the proper drag of unblanking to produce to opener 20, as can be seen from Figure 6, the antetheca 62 of the bottom 58 of opener departs from vertical line α angle, and direction tilts inwardly, for example towards the axis 64 of fixture 34.So, if the paper of circular element 14 clampings produces bigger active force, be tending towards opening circular element, when mechanism 20 is in locked position, can prevent that this kind of thing and take place, because at this moment the active force of Chan Shenging is tending towards making antetheca 62 to move right, as shown in Figure 6, between upper junction member 24 and bearing track 32, promote extruding antetheca 62 thus, thereby mechanism 20 is remained on locked position of coupler.Particularly, along antetheca 62, less times greater than the distance between upper junction member 24 and the bottom bearing track 32, this moment, bearing track 32 pressurizeds moved down in the distance between the bottom surface of plane 60 and projection 56, so that produced the effect of good promotion extruding locking.

The upper end 62a of antetheca 62 has smooth fillet, so, when mechanism 20 moves, can not cut or scratch the downside of pedestal 12.

Locking ring binder

10 and 50 advantage are to be convenient to open this class attachment means.And the paper of bookbinding in ring binder can not come off from circular element.Yet the advantage that opener is supported on the lower junction member outside and upper junction member inside is: can enough machinery be installed by ring binder.

Accompanying drawing 11,12 and 13 expressions first embodiment of the present invention, the opener of the ring binder shown in the opener shown in it and Fig. 6-10 is roughly the same, but the attachment means shown in Figure 11～13 is provided with the another kind of device that supports unlatching/blocking mechanism.In Figure 11-13,, add 100 again with corresponding digital and represent with part identical in Fig. 6～10.

In the embodiment shown in Figure 11～13, on lower junction member 130, be provided with two outward extending lugs 180, support the ridge 152 of unlatching/blocking mechanism 120 with lug 180.Opener 120 always contacts with lower junction member 130, and is attached thereto.Ridge 152 is positioned on the upper surface of lug 180, and projection 154 (be represented by dotted lines among the figure, and similar to projection shown in Figure 10 54) is against the lower surface of bearing track 132.

Adopt with bearing track 132 identical materials and form lug 180, so that lug can strain, in the process that attachment means is installed, unlatching/blocking mechanism 120 is positioned the installation site in the clamping engagement mode.

During meshing, unlatching is connected with the lower junction member with blocking mechanism, and can turn round in the certain angle scope around the axis that passes ridge 152.

In making installation process, ring binder is installed in the above described manner can be prevented that opener from skidding off from fuselage.And, shown in Figure 12 and 13, when unlatching/blocking mechanism 120 is in locked position of coupler, antetheca 162 extruding upper junction members 112, elasticity lug 180 applies active force to ridge 152.The first, produce a certain amount of resistance at locked position elasticity lug 180, the ring binder of feeling that gives the user is locked; The second, bias force makes antetheca 162 remain on the position of departing from vertical line.

That is, make antetheca 162 depart from the angle of vertical line, suitably select the shape of upper junction member 112 and the elasticity of lug 180, at locked position, unlatching/retaining mechanism just has clamping action.

Accompanying drawing 14 and 15 expressions, second embodiment of the present invention.Accompanying drawing 14A represents and similar blocking mechanism shown in the accompanying drawing 6-10 with 14B.A problem for this retaining mechanism is: when ring binder (shown in Fig. 6-10 like that) when being in the enable possition, open and retaining mechanism 20 is forced into position shown in Figure 14 A, very little gap H is only arranged in this position ₁, gap H ₁Between the outward flange and attachment means 10 residing horizontal planes of mechanism 20.

At this horizontal plane, attachment means 10 with around lid (not shown) or lid settle surface thereon to link to each other.Therefore, be difficult to handle unlatching/blocking mechanism in this position, unless make the opening L of circular element 14 ₁Reduce,, like this, can reduce again paper is put into available extended distance on the ring binder so that mechanism 20 is inclined upwardly.

Shown in Figure 15 A and 15B, in order to overcome above-mentioned defective,, on upper junction member 112, be provided with lip 184 according to second embodiment of the present invention, lip 184 is on the upper junction member 112, at the jut that tilts above outwards with unlatching/blocking mechanism 120 opposite end central portions.Formed the sunk part 186 of direction outwardly thus.This sunk part makes mechanism 120 have the free gyration of certain limit, so that be engaged at beveled end 163 before the lip 184 of upper junction member, can apply certain downward active force (184 point actions of part, be subjected to the unlatching/blocking mechanism of its support, under the counter-force effect of this fulcrum, move down, but thereby force bottom revolving structure spare to move down, so closed hoop element 114).In other words, unlatching/blocking mechanism 120 can be around lip 184 revolutions of upper junction member, order about the lower junction member and move to second settling position (for example closure and lockset position of coupler) from first settling position (for example open and lockset position of coupler), unlatching/blocking mechanism 120 scope and lip 184 at a certain angle disengages (being this angle in the part enable possition shown in Figure 15 a with as shown in Figure 8 between the full open position of attachment means).

This free rotating range of movement makes when opener and the engagement of upper junction member, the gap H between opener and the lid (dotted line among the figure) ₁Rise to H ₂, shown in Figure 15 a.Yet, the opening L of attachment means in Figure 15 b ₂Opening L with attachment means among Figure 14 b ₁Keep identical.

At closed and locked position (as shown in figure 12), can see that unlatching/blocking mechanism 120 does not contact with sunk part 186, and contact with the lands of upper junction member.
