With the technology of patent documentation 3,, can less aperture just not stop the device of rotating ring but be provided with, so have opening angle instability, the problem that the loose-leaf of file is at random though can lessly take out or put into loose-leaf with gap.
Therefore, the technical problem to be solved in the present invention is to provide a kind of loose-leaf binder, to solve the problems referred to above of the said goods, and this loose-leaf binder integral body is plastic products, but rotating ring divides two stages to carry out opening action, can prevent that loose-leaf from coming off accidentally, and the 1st narrow open mode that can plug a small amount of loose-leaf can be provided, and can plug the 2nd broad open mode of most loose-leaves.
According to the present invention, a kind of solution loose-leaf binder of the problem of the said goods as mentioned above is provided, it has following structure on constituting.
Also promptly, the invention provides a kind of loose-leaf binder 10,100,
It comprises: panel-shaped base body 16, and it is provided with two retainer rings 14 along the 1st side edge part 12; And fulcrum 22, its the 2nd side edge part 18 along matrix is configured in the fulcrum supporting groove 20 set in the matrix, but and free bend and FREE TORSION, and rotate and freely be supported in the bearing portion 24 of matrix, on two positions of each end side, the notch part 26 that possesses by matrix is exposed to outside large-diameter portion 28, but be equipped with in the periphery of each large-diameter portion and cooperate with the said fixing ring and form two rotating rings 30 of endless loop, but retainer ring 14 and rotating ring 30, but possesses the strain of utilizing this fulcrum and rotating ring respectively and the hook-shaped clamping close device 32 that engages with each other at leading section
Fulcrum 22 has front cam 34,134,104 and the back cam 36,136,102 that separates in a circumferential direction and give prominence on radial direction,
Matrix 16 has the 1st fastener 40,140,108 of above-mentioned front cam contact when fulcrum 22 rotates and the 2nd fastener 42,142,106 of above-mentioned back cam contact,
But when making rotating ring be engaged to retainer ring, front cam 34,134,104 contacts the 1st fastener 40,140,108, on fulcrum 22, produce the 1st reaction force with the 1st bending of reversing along with fulcrum 22, when but retainer ring and rotating ring are in the endless loop state, but the 1st reaction force acts is strengthened above-mentioned two hook-shaped clamping close devices engaging power each other in the direction of opening rotating ring, on the other hand, after the engaging releasing with above-mentioned two hook-shaped clamping close devices, but the 1st reaction force can make rotating ring open automatically from retainer ring
But broken away from above-mentioned two hook-shaped clamping close devices under the 1st open mode of rotating ring, above-mentioned back cam 36,136, the 102 and the 2nd fastener 42,142, after 106 engagings, but but further the opening limited and between above-mentioned rotating ring front end and retainer ring front end, form the gap to take out or to put into loose-leaf of rotating ring, when above-mentioned movable circulating application being added the 2nd crooked and the 2nd reaction force that produce is bigger when opening the power of direction along with above-mentioned fulcrum 22, become following the 2nd open mode, cam 36 promptly, 136,102 overcome the 2nd fastener 42,142,106 card ends power, and cross the 2nd fastener, but the leading section of above-mentioned rotating ring further separates from the leading section of said fixing ring.Like this, can realize two stage open mode according to the present invention.

The specific embodiment
With reference to Fig. 1~Fig. 7 the present invention the 1st embodiment is described.
Fig. 1 represents loose-leaf binder integral body of the present invention with numbering 10.Loose-leaf binder 10 is identical with previous equal product, possesses: panel-shaped base body 16, and it is set with two retainer rings 14 along the 1st side edge part 12; And fulcrum 22, it is configured in the fulcrum supporting groove 20 set in the matrix along matrix the 2nd side edge part 18, but and free bend and FREE TORSION.Fulcrum 22 rotates and is supported in freely in the bearing portion 24 set on each end position of matrix 16.As Fig. 2 and shown in Figure 3, flexible and must have fully wide groove width in order to make fulcrum 22, so that only the both ends of fulcrum 22 are supported by bearing portion 24, and mid portion is a free state in fulcrum supporting groove 20.At two positions of each end side, the notch part 26 that possesses by matrix is exposed to outside large-diameter portion 28, but cooperates with retainer ring 14 and form two rotating rings 30 of endless loop prominent the establishing of the periphery of each large-diameter portion 28.But retainer ring 14 and rotating ring 30, identical with previous corresponding goods, front position at this ring possesses the hook-shaped engaging arm device 32 that faces with each other along matrix 16 length directions, but in order to utilize fulcrum 22 to engage with each other the endless loop state of keeping with the strain of rotating ring 30.One side's hook-shaped clamping close device is a hook, and the opposing party's hook-shaped clamping close device is a dog hole.
Embodiment 1
The fulcrum 22 of the loose-leaf binder of the 1st embodiment, has triangular shape cam 38 in the centre position of its length direction, this triangular shape cam 38 have along the circumferential direction go up separate and radial direction on the front cam 34 of extending and back cam 36 (but the former is " preceding " when opening rotating ring 30, continue its latter be " after "), on the other hand, matrix 16 has the 1st fastener 40 and the 2nd fastener 42 that front cam 34 when being configured to fulcrum 22 turns and back cam 36 contact respectively in different turns position.
Front cam 34 and back cam 36 are arranged on the centre position of fulcrum 22 long side directions, the 1st fastener 40 and the 2nd fastener 42, be formed on matrix 16 the 2nd side edge part 18, the inboard of outstanding sidewall sections 44 shown in Figure 1 for example, be formed on these sidewall sections 44 medial segment portions and constitute the 1st fastener 40, constitute the 2nd fastener 42 from the inner surface portion of the upwardly extending sidewall sections 44 of interior acies of medial segment portion.
When but rotating ring 30 and retainer ring 14 are engaged with each other, front cam 34 as shown in Figure 4 be about to close the time the position contact the 1st fastener 40.When but this state makes rotating ring 30 that 32 of the clamping close devices of each leading section are engaged with each other to become endless loop state shown in Figure 5 with finger, want to rotate reluctantly fulcrum 22 and the 1st fastener 40 is applied pushing force, along with reaction force reverses via front cam 34.Meanwhile and since the cam portion of fulcrum 22 from its former central axis to the direction bending of arrow L shown in Figure 5 both set a distance 1, therefore a part of reaction force that reverses disperses in fulcrum as the reaction force of bending.Thus, fulcrum 22 is applied structural inadequate power obtain relaxing, and can improve the validity of the reaction force that reverses (below, be called the 1st reaction force) effect.
But the rotating ring 30 of recurrent state is to the effect of the power of opening the slight tractive of direction because the performance of the 1st reaction force is checkmated, and act on the fastening state direction of strengthening clamping close device 32 (being constituted) by hook and dog hole, therefore can make respectively encircle key element more firmly each other card end and do not rock, even be subjected to a certain degree external force effect at the endless loop state, also can stably keep the endless loop state.
On the other hand, but rotating ring 30 exists, the direction of arrow as Fig. 1, but for example push rotating ring 30,30 etc. simultaneously and after but the clamping close device 32 that makes the rotating ring side breaks away from from the clamping close device 32 of retainer ring side with thumb and forefinger direction towards each other, instead flexibly and automatically open because of above-mentioned the 1st reaction force immediately, and stop at front cam 34 and the 1st fastener 40 position contacting, and the inner surface of back cam 36 and sidewall sections 44 that is the 1st open mode between the 2nd fastener 42 position contacting under (with reference to Fig. 4).Under this state, but open the degree that can plug loose-leaf by a small margin between retainer ring 14 and the rotating ring 30.Moreover, be the 2nd fastener 42 position contacting also if regulation satisfies the inner surface of front cam 34 and the 1st fastener 40 contact positions and back cam 36 and sidewall sections 44 simultaneously, but then the 1st open mode of rotating ring can be the fixed position.Afterwards, after with finger but rotating ring 30 further being opened, back cam 36 and fulcrum 22 turn in the lump, make fulcrum 22 to direction bending shown in Fig. 6 arrow LL both set a distance ll, and on the 2nd fastener 42, slide, be accompanied by because of reaction force that this bending produces (below, be called the 2nd reaction force) pushing the 2nd fastener 42.During this period, but because the 2nd reaction force is to make the spring force of rotating ring 30 to the closing direction rotation, therefore unclamp after the hand, the 2nd ring key element returns to state shown in Figure 4 immediately automatically.
Then, as shown in Figure 6, when after the top of cam 36 with after the 2nd fastener 42 contacts, do not brought into play the effect of revolving force at this position the 2nd reaction force.Then, but after the power that with finger rotating ring 30 is applied limpingly above open loop direction the 2nd reaction force, the top of back cam 36 surpasses the 2nd fastener 42, but rotating ring 30 moves to the 2nd open mode as shown in Figure 7.Moreover the angle that back cam is crossed the front and back of the 2nd fastener can be depending on outstanding size of back cam radius direction and setting arbitrarily.So the reason of set angle is, the middle body of fulcrum becomes the free state that is not subjected to the restriction of fulcrum supporting groove, thereby can be crooked significantly.Under this state, can there be most states of opening to plug with overlapping on loose-leaf in ring.
Generally speaking, but fulcrum 22 and rotating ring 30 are made by the resin with high nerve, matrix is made by the resin of shape stability height and high rigidity, if for example, but fulcrum 22 and rotating ring 30 are made for Merlon, making matrix is that ABS resin is made, if use this material then can form above-mentioned formation.Also identical in following examples.
As mentioned above, according to the present invention, but when rotating ring self closing state was opened, therefore the 1st open mode in the middle of can carrying out and move than two stages of its 2nd open mode of opening by a larger margin can utilize the arbitrary open mode in this two states.In addition, owing to can as patent documentation 1, not open ring quickly, therefore there are not loose-leaf misgivings at random.
Embodiment 2
Fig. 8~Figure 11 illustration the 2nd embodiment of the present invention.Among the 2nd embodiment, front cam 134 and back cam 136 are formed on the direction opposite with the 1st embodiment of fulcrum 22.In addition, the 1st fastener 140 and the 2nd fastener 142, constituted by the 2nd side edge part 18 of matrix 16 and than the ribs 46 of fulcrum 22 more close inboards, constitute the 1st fastener 140 from the observed medial segment of the groove side portion that is formed on this ribs 46, constitute the 2nd fastener 142 from the extendible inner surface portion of acies of the above-mentioned medial segment portion of ribs 46.
Identical with the 1st embodiment, but when rotating ring 30 and retainer ring 14 were engaged with each other, front cam 134 contacted the 1st fastener 140 in the front position of closing as shown in Figure 8.When but the clamping close device 32 that makes each leading section make rotating ring 30 further turns from this state engages with each other and becomes endless loop state shown in Figure 9, want the fulcrum 22 of rotation reluctantly the 1st fastener 40 to be applied pushing force, be accompanied by reaction force and reverse via front cam 134.Meanwhile, fulcrum 22 cam portions are to the crooked predetermined distance l ' of the direction of arrow L ' shown in Figure 9, and a part of reaction force that reverses is disperseed as the reaction force of bending.Thus, identical with the 1st embodiment, fulcrum 22 is applied power inadequate on the structure obtain relaxing, and improve the validity of the effect of the 1st reaction force that reverses generation.
The rotating ring 30 of recurrent state is to the effect of the power of opening the slight tractive of direction but the performance of the 1st reaction force is checkmated, and act on the fastening state direction of strengthening clamping close device 32 (being constituted) by hook and dog hole, therefore make respectively encircle key element more firmly each other card end and do not rock, even the endless loop state is subjected to external force effect to a certain degree, also can stably keep the endless loop state.
On the other hand, identical with the 1st embodiment, but utilize thumb and forefinger direction towards each other to push rotating ring 30,30 etc. simultaneously and after but the clamping close device 32 that makes the rotating ring side breaks away from from the clipping means 32 of retainer ring side, but rotating ring 30 is immediately because of above-mentioned the 1st reaction force ground that rebounds, automatically open, and front cam 34 and the 1st fastener 40 position contacting, and the inner surface of back cam 36 and sidewall sections 44 that is the 1st open mode shown in Figure 8 between the 2nd fastener 42 position contacting under stop.But be opened to the degree that can plug loose-leaf by a small margin between retainer ring 14 and the rotating ring 30 under this state.Thereafter, after but rotating ring 30 is further opened, back cam 136 and fulcrum 22 turn in the lump, make fulcrum 22 under the state of direction bending shown in Figure 10 arrow LL ' both set a distance ll ', on the 2nd fastener 142, slide, be accompanied by the 2nd reaction force that produces because of this bending and push the 2nd fastener 142.During this period, but because the performance of the 2nd reaction force makes the effect of rotating ring 30 to the spring force of closing direction rotation, so unclamp after the hand, but rotating ring 30 returns to state shown in Figure 8 immediately automatically.
Then, as shown in figure 10, when after the top of cam 136 with after the 2nd fastener 142 contacts, just no longer bring into play the effect of revolving force at this position the 2nd reaction force.Then, but after the power that with finger rotating ring 30 is applied limpingly above the 2nd reaction force of open loop direction, move to the 2nd open mode as shown in figure 11 above the 2nd fastener 142 at back cam 136 tops.

As Fig. 1 and shown in Figure 2, the fulcrum supporting groove 20 of matrix 16, from the triangular shape cam 38 of fulcrum 22 leave each side the position, with the position of each bearing portion 24, possess that having comes off towards prominent the 1st fulcrum of establishing of the interior side of fulcrum supporting groove 20 prevents projection 48.Be arranged at the 1st fulcrum of each side position that leaves from triangular shape cam 38 come off prevent projection 48, coming off with the 1st fulcrum that is arranged at the position of each bearing portion 24 prevents that though projection 48 from reverse each other configuration, also can dispose in the same way.Because the diameter of fulcrum 22 is much smaller than the diameter of fulcrum supporting groove 20, therefore, if fulcrum 22 is pushed in the fulcrum supporting groove 20 reluctantly, then the 1st fulcrum comes off and prevents that projection 48 and its subtend wall from producing strain, fulcrum surpasses projection 48 easily and is embedded in the fulcrum supporting groove 20, and can prevent to come off by this projection 48.
Further, come off and prevent projection 50 but also can the 2nd fulcrum be set at prominent each large-diameter portion 28 of establishing rotating ring 30 fulcrums 22, but its in the turn scope of rotating ring 30 along becoming lower circumference direction part the prominent arcuation that is made as.Because the 2nd fulcrum comes off and prevents projection 50, when loose-leaf binder being installed to the situation of clamping plate lining paper etc., distance between large-diameter portion 28 positions minimizing fulcrum 22 and clamping plate lining paper (not icon), even therefore but rotating ring 30 is pushed into clamping plate lining paper side in its turn scope, fulcrum 22 can not come off yet.
And then, as Figure 12 and Figure 23, also can the 3rd fulcrum be set and come off and prevent projection 52 at fulcrum 22, it is by being formed to the projection of the outstanding set distance of fulcrum central authorities from the boundary position with above-mentioned each large-diameter portion 28.The 3rd fulcrum comes off and prevents projection 52, on fulcrum 22, but before making rotating ring 30 and retainer ring 14 cooperates, contact and a fixed pivot axis 22 with the inwall 54 of fulcrum supporting groove 20, thereby the generation fulcrum comes off and prevents effect, and the contact resistance by this moment makes fulcrum 22 follow reaction force (below, be called the 3rd reaction force) to produce reversing of appending property.
Also there is following effect in the 3rd reaction force, but promptly when rotating ring 30 and retainer ring 14 are in the endless loop state, forms the endless loop state of more strengthening but affact rotating ring 30 in the lump with the 1st reaction force that has before illustrated.Moreover, make as the come off inwall 54 of the projection contact that prevents projection 52 of the 3rd fulcrum, in the fulcrum supporting groove 20 of can packing into separately as shown in figure 12, or provide by integrally formed tunnel-like bearing portion 56.
Embodiment 3
Below, with reference to Figure 13~Figure 22 the 3rd embodiment of the present invention is described.
The 3rd embodiment integral body of representing loose-leaf binder of the present invention among Figure 13 with numbering 100.Loose-leaf binder 100, identical with the loose-leaf binder of the 1st embodiment and the 2nd embodiment, have the panel-shaped base body 16 that is set with two retainer rings 14 along its 1st side edge part 12, but and be configured in the fulcrum supporting groove 20 that is provided with in the matrix and the fulcrum 22 of free bend and FREE TORSION along the 2nd side edge part 18 of matrix.
The fulcrum 22 of the loose-leaf binder 100 of this 3rd embodiment has: the back cam 102 that extends along radial direction in the centre position of its long side direction, and locate in these back cam 102 each sides and near each large-diameter portion 28 and front cam 104 that the circumferential locations of fulcrum and back cam 102 are different.In addition, matrix 16 has and is configured in fulcrum 22 front cam 104 and back cam 102 contact respectively when rotating the 1st fastener 108 and the 2nd fastener 106.
The 1st fastener 108, as Figure 15,16 and 18 the clearest and the most definite illustrations, outstanding to fulcrum 22 from the sidewall sections inner surface of the 2nd sidepiece 44 that constitutes matrix 16.On the other hand, the 2nd fastener 106,, and outstanding clipping groove 20 to the direction of fulcrum 22 with the integrally formed matrix 16 of the 1st fastener 108 opposition sides.
Moreover, among other not shown embodiment, each fastener of the 1st and the 2nd also can be opposite configuration, also be, the 1st fastener is arranged on the inboard of matrix the 2nd sidepiece, and the 2nd fastener is arranged on the ribs of matrix, make each cam part of the 1st and the 2nd be configured to and can contact with this each fastener.
When but rotating ring 30 and retainer ring 14 were engaged with each other, front cam 104 contacted the 1st fastener 108 in the front position of closing as shown in figure 17.But when making rotating ring 30 that the clamping close device 32 of each leading section is engaged with each other to become Figure 15, endless loop state shown in Figure 17 with finger from this state, want the fulcrum 22 of rotation reluctantly the 1st fastener 108 to be applied contact force, along with the 1st reaction force reverses via front cam 104.
The rotating ring 30 of recurrent state is to the effect of the power of opening the slight tractive of direction but the performance of the 1st reaction force is checkmated, and act on the direction of the fastening state of strengthening clamping close device 32 (being constituted) by hook and dog hole, therefore make respectively encircle key element more firmly each other card end and do not rock, even and under the endless loop state, be subjected to a certain degree external force effect, also can stably keep the endless loop state.
On the other hand, identical with the embodiment of Fig. 1, but with finger simultaneously to the direction of arrow make rotating ring 30,30 crooked near and after clamping close device 32 is broken away from, but rotating ring 30 is immediately because of rebound ground and automatically opening of above-mentioned the 1st reaction force, and in front cam 104 and the 1st fastener 108 position contacting, and afterwards stop (with reference to Figure 19) under the 1st open mode between cam 102 and the 2nd fastener 106 position contacting.But open the degree that can plug loose-leaf by a small margin between retainer ring 14 and the rotating ring 30 under this state.
Thereafter, after with finger but rotating ring 30 further being opened, back cam 102 and fulcrum 22 turn in the lump, fulcrum 22 is slided to direction bending shown in Figure 20 arrow LL both set a distance ll and on the 2nd fastener 106, along with the reaction force that produces because of this bending (below, be called the 2nd reaction force) pushing the 2nd fastener 106.During this period, but because the performance of the 2nd reaction force makes the effect of rotating ring 30 to closing direction rotation spring force, so the 2nd ring key element returns to Figure 18 or state shown in Figure 17 immediately automatically after unclamping hand.
Then, as shown in figure 20, with after the 2nd fastener 106 contacts, do not brought into play the effect of revolving force at this position the 2nd reaction force at cam 102 tops, back.Then, but after the power that with finger rotating ring 30 is applied limpingly above the 2nd reaction force of open loop direction, back cam 102 tops are above the 2nd fastener 106, but rotating ring 30 is as Figure 21, the 2nd open mode that moves to shown in Figure 22.Moreover the angle that back cam is crossed the front and back of the 2nd fastener can be depending on the outstanding size on the radial direction of back cam 102 and sets arbitrarily.So the reason of set angle is, the free state of the middle body of fulcrum for not limited by the fulcrum supporting groove, thus can be crooked significantly.Under this state, can there be most states of opening to plug in ring with overlapping on loose-leaf.
As shown in figure 15, in the fulcrum supporting groove 20 of matrix 16, possess in the position of each bearing portion and the position of two large-diameter portion axis direction inboards, coming off towards the interior side of fulcrum supporting groove 20 and towards the 1st fulcrum that the interior pleurapophysis of fulcrum 22 is established prevents projection 48.The 1st fulcrum comes off and prevents that projection 48 from disposing each other in the same way in this example, but also can dispose each other incorgruously.Because fulcrum 22 is much smaller than fulcrum supporting groove 20 diameters, therefore if fulcrum 22 is pushed in the fulcrum supporting groove 20 limpingly, then the 1st fulcrum comes off and prevents that projection 48 and its subtend wall from producing strain, fulcrum surpasses projection 48 easily and is embedded in the fulcrum supporting groove 20, and this thus projection 48 prevents to come off.
In addition, the loose-leaf binder of the 1st embodiment, the 2nd embodiment and the 3rd embodiment all integral body is made for plastics, for example fulcrum 22 is formed by tough as the Merlon for example and rubber-like nerve resin, and other member is formed by the high resin of shape stability of for example ABS of high rigidity.
In addition, but among the action of the closing direction of rotating ring and the embodiment 1 illustrated action identical in fact.
If the action of blanket the foregoing description 1~3 is then as described below.
Open in order to encircle the self closing state, but the direction pushing that at first the rotating ring front end is broken away from each other to two hook-shaped clamping close devices with finger.For example, hook-shaped clamping close device with a pair of retainer ring is arranged on the loose-leaf binder axis direction outside as shown in Figure 1, and but the hook-shaped clamping close device of a pair of rotating ring is arranged on loose-leaf binder axis direction inboard, but the hook-shaped clamping close device that all right one way or the other rotating ring is made rotating ring to the pushing of the other side's direction breaks away from from the hook-shaped clamping close device of retainer ring.
Because front cam is subjected to the 1st reaction force from the 1st fastener, but therefore rotating ring becomes the 1st open mode automatically, and extremely the back cam contacts till the position of the 2nd fastener, maintains the 1st open mode.
For but rotating ring is guided to the 2nd open mode from the 1st open mode to opening direction, but to opening further pushing rotating ring of direction.Then back cam is crossed the 2nd fastener and is moved to the 2nd open mode if this pushing force surpasses the 2nd reaction force.
On the one hand, when wanting to close endless loop, but with the finger press rotating ring, after but rotating ring is closed with respect to retainer ring from the 1st open mode, front cam is fastened on the 1st fastener, antagonism thereby the 1st reaction force that produces push movable hoop retainer ring, and its these hook-shaped clamping close devices are only blocked each other.The 1st reaction force acts is arranged under this closed condition, be reinforced, rock, under external force effect to a certain degree, still can keep card in addition and end state thereby make the leading section that encircles not have so card ends power.
On the other hand, from the 2nd open mode closing to the 1st open mode, after with the direction pushing of finger with movable hoop retainer ring, back cam engages with the 2nd fastener, after antagonism thereby the reaction force (may not be identical with the 2nd reaction force) that produces and the further pushing, but back cam is crossed the 2nd fastener and make rotating ring become the 1st open mode.
More than, describe the present invention with reference to embodiment, but be understood that and can in the present invention's scope, carry out various changes.
