Description

Ring binder

The present invention relates to the used annular binder of loose-leaf binder or similar articles.

Binder shape member has multiple form known, and it all can move between a closing position and an enable possition so that allow paper or similar articles take out in this ring.

This kind annular construction member has the problem that is difficult to open, and the large-sized annular member of powerful closing force of especially possessing in order to prevent paper from dropping out ring is even more serious.Some known annular construction member has attempted to overcome this puzzlement, but, and their complicated design, and need artificial assembling when making.

The objective of the invention is to solve the above problems.

Wherein comprise a pedestal that supports many rings according to ring binder folder of the present invention, and the opener that is separately positioned on these pedestal two ends, this opener is in order to open these rings; Each opener contains locking device so that opener is locked in closing position; Pedestal has a rigidity upper mechanism in order to support a pivotable lower mechanisms, ring system is installed on this lower mechanisms, the invention is characterized in, on two ends of binder, opener system is pivotably mounted between lower mechanisms and the upper mechanism, and in the outside of lower mechanisms, and in the inside of upper mechanism.

After the benefit that ring is locked is this lock opened, this annular folder can be opened easily, and can on annular folder, not disperse at the paper on the annular folder, to support the advantage of this opener then for coming this annular folder of automation ground assembling by machine at the external mode of lower mechanisms and in the inside of upper mechanism mode.

The pedestal of opener applies and acts on the following to force this lower mechanisms to move up and pivot of pivotable lower mechanisms, makes ring on it separated from one another and open whereby.

The pedestal of opener applies the end face that acts on pivotable lower mechanisms, to force this lower mechanisms to move down and to pivot.

Suitably, but this locking device comprises the protuberance on the protruding part corresponding matching upper mechanism bottom surface.In more detail, when opener was pushed to the outside, this protruding part just separated with this convex portion.

Another way is the part that locking device comprises opener, and this part is between the upper mechanism of pedestal and lower mechanisms and surmount the center.

The wedged part of opener has a top-surface camber portion can be connected the upper mechanism of corresponding bending, and the bottom of this part has one to be connected the end face that part can be connected lower mechanisms in addition.

The protuberance that opener stretches out with respect to the end of upper mechanism at least, and between upper mechanism and lower mechanisms, move pivotally.

In addition, the whole outboard end of upper mechanism is not blocked haply.

Below, with reference to accompanying drawing and by embodiment the present invention is illustrated.

Figure 9 shows that the perspective view and the cut-away section of the annular folder of Fig. 6, and be in the state of closure and locking;

Figure 10 shows that the perspective view and the cut-away section of the annular folder of Fig. 6, and be in the state of closure and locking.

The annular folder 10 that binder shown in Fig. 1 to Fig. 5 is used is distributed in ring 14 on the pedestal (shown in Fig. 4 and Fig. 5 one of them) and is arranged on unlatching and locking mechanism 20 (one of them only is shown among the figure) on the pedestal two ends comprising a pedestal 12, three.

Pedestal 12 comprises a firm upper mechanism 24, and the cross section of this upper mechanism is bending and supporting one pivotable lower mechanisms 30 between an overlapping side 26.And lower mechanisms 30 is provided with two holder rails 32 that can pivot mutually on the longitudinal axis of folder 10.

Ring 14 is installed on the pivotable lower mechanisms 30, and more particularly, an assembly 14a of each ring system is installed on a certain holder rail 32, and another assembly (not shown) of each ring then is installed on another holder rail (not shown).

Tightening device 34 is located on the upper mechanism 24 so that annular folder 10 is fixed on a paper strip of paper used for sealing or the similar object.。By the unlatching on holder rail 32 ends and the effect of locking mechanism 20, two holder rails 32 can correspondingly move (promptly pivoting) each other between a lower and an eminence.

But be bearing in the two ends of upper mechanism 24 opener 20 pivoteds and be connected the two ends of pivotable lower mechanisms 30, so that opener is placed between upper mechanism and the lower mechanisms.More particularly, by Fig. 4 and Fig. 5 as can be known, the two ends of opener 20 respectively are provided with

protuberance

33 and 35 one on the other, these

protuberances

33,35 are looped around within the warpage end 37 of upper mechanism 24 each end 26, but

protuberance

33 and 35 be positioned at outboard end 39 outside of holder rail 32 and respectively above this outboard end 39 and below, so that allow lower mechanisms 30 and upper mechanism 24 the two mutually combine and locate, and allow and open mechanism 20 and be supported in pivotly between lower mechanisms 30 and the upper mechanism 24.In addition, opener 20 is installed between upper mechanism and the lower mechanisms and can makes pivotal action, but in other cases, then is fixedly mounted between the said two devices and (promptly can't does lateral movement or the like).

For can make opener 20 easily and automation be installed in upper mechanism 24 and lower mechanisms 30 between the two, neither sagging wing flap or the protuberance of being subjected to of the whole outboard end of upper mechanism 24 hinders.Therefore, when installing to opener 20 on the annular folder,, and then the overlapping 37 of each end 26 of upper mechanism is pushed shrinkage (crimped) just can together as long as opener 20 is directly inserted top and

lower mechanisms

24,30 between the two.Because side does not have sagging wing flap or protuberance outside the upper mechanism 24, so can additionally obtain saving the benefit of material.Thus, the comparable existing structure of the present invention is saved 2～4% materials.

This annular folder has a latched position (as shown in Figure 1) and two unlocked positions (as shown in Figures 2 and 3).

For realizing above-mentioned situation, two ends of opener 20 respectively are provided with the protuberance 38 of one first protruding part 36 with upper mechanism 24 belows of cooperation pedestal.

The annular folder has two closing positions (seeing also Fig. 1 and Fig. 3) and an enable possition (seeing also Fig. 4).

For realizing above-mentioned state, have on the opener 20 second protruding part 40 be connected pivotable holder rail 32 below.

More particularly, lock-out state system is achieved with 38 cooperating of the two of protuberance by first protruding part 36, thus, when being positioned at the position of closure and locking (as shown in Figure 1), protruding part 36 is positioned at a side of protuberance 38, and when being positioned at unlocked position (as shown in Figure 2), 36 opposite sides that are positioned at protuberance 38 of protruding part.When closure and latched position, protruding part 40 does not contact below holder rail 32, therefore, ring 14 is in sufficiently closed position, and when closure and unlocked position, then protruding part 40 can touch the following of holder rail 32 and cause holding in the palm rail 32 up to move (the holder rail upwards being pivoted but still be unlikely) slightly.

Open ring 14, protruding part 40 is connected firmly hold in the palm rail 32 below, whereby, these upwards springs of holder rail (that is the ejection that pivots), at this moment, 14 complete openings of ring, and therefore annular folder 10 also is in the position (seeing also Fig. 3) of unlatching and non-locking.

In addition, unlatching and locking mechanism 20 have one the 3rd protruding part 42, and it both can form the ring 14 direct closures that are in unlatching and unlocked position the position of closure and locking; Also can be with ring 14 directly from opening and unlocked position is closed into the position of closure and non-locking.More particularly, the 3rd protruding part 42 has upper surface that male part 44 is engaged on holder rail 32 to force the holder rail and move down and to pivot downwards.

Similar notion is arranged at the annular binder shown in Fig. 6 to Figure 10 50 and Fig. 1 to annular binder 10 shown in Figure 5.Main difference between the two is to open and the structure of locking mechanism 20.

The opener 20 of the annular folder 50 that Fig. 6 is extremely shown in Figure 10 is to be supported on pivotly on two ends of rigidity upper mechanism 24, and combine on each end with pivotable lower mechanisms 30, so so that opener 20 is positioned between upper mechanism and the lower mechanisms regularly.Specifically, the distolateral inside of flattening end 37 (the dotted line places of Fig. 9) that each overlapping 26 that a protuberance 52 (please refer to Fig. 9 and Figure 10) is centered around upper mechanism 24 is arranged of each of opener 20.But this protuberance 52 still is in the outside of the outboard end 39 that holds in the palm rail 32 so that in conjunction with also putting this protuberance 52 regularly between lower mechanisms 30 and upper mechanism 24.Moreover opener 20 is to be installed between top and the lower mechanisms to make pivotal action, but other situation then belongs to installation regularly (promptly not having lateral movement to take place).

lower mechanisms

24,30 between the two.Because the outboard end of upper mechanism 24 does not have sagging wing flap or protuberance, so can additionally obtain saving the benefit of material.Thus, the comparable structure in the past of the present invention is saved 2～4% material.

Annular folder 50 has two closing positions (seeing also Fig. 6 and Fig. 7) and an enable possition (seeing also Fig. 8).Be similar to the annular folder 10 among Fig. 1.

For forming this state, opener 20 each end have different connecting devices, and also promptly first connecting device is the shape of protruding part 54, so that cooperate the lower surface of pivotable holder rail 32; And second connecting device also is the shape of protruding part 56, to be connected the upper surface of the holder rail 32 that can pivot.

Specifically, when closing position shown in Figure 7, male member 54 be connected holder rails 32 below, and bar 20 is when further mobile laterally, causes male member 54 to push the top from holding in the palm to below the rail, to reach enable possition shown in Figure 8.After this, when opener is pulled inward when regarding it as closed ring, male member 56 acts on the end face (as shown in Figure 8) of the holder rail 32 of open position, so that will ask rail 32 to shift Fig. 6 or closing position shown in Figure 7 downwards onto.

Be similar to annular folder 10 shown in Figure 1, this annular folder 50 also has a latched position (as shown in Figure 6) and two unlocked positions (as shown in Figures 7 and 8).In more detail, this locking mechanism 20 has one " b " tee section, and the tip side of the base portion 58 of " b " tee section then has pair of planar 60 can lean lower surface at upper mechanism 24.When unlocked position shown in Figure 7, this top plan 60 is separated from one another with the bottom surface of upper mechanism 24; But, in case locking mechanism 20 moves to the inside, when surface 60 just touched upper mechanism 24, preferably male member 56 also touched holder rail 32 tops.

Especially from Fig. 6 as can be known, an antetheca 62 of opener base portion 58 surmounts a central angle [alpha] and inwardly towards the axle 64 of fastener device 34, can have an inherent resistance to be disengaged locking to prevent opener 20 like this.Therefore, when being applied one by ring 14 paper of holding of detaining when being intended to open the big strength of ring, the opener 20 that then is in latched position can be resisted above-mentioned strength, because above-mentioned strength can force antetheca 62 to removable, as shown in Figure 6, but the antetheca 62 of wedging base portion 58 and tends to opener 20 is maintained on the latched position between upper mechanism 24 and holder rail 32 like this.In more detail, when being pressed down, antetheca 62 is being a bit larger tham the two distance of upper mechanism 24 and holder rail 32 between the two distance system of the bottom surface of plane 60 and male member 56, locks and the effect of wedging so can reach.

The top 62a of antetheca 62 is made to smooth circular arc, and when moving with convenient opener 20, top 62a can not hurt or the bottom surface of scratch pedestal 12.
