Abstract
The invention discloses a clamping ring metal piece with twist lock type clamping rings. Each clamping ring comprises a pair of semi-rings, and when the clamping ring is needed to be closed, the tail end of each semi-ring is interlocked with that of the other semi-ring so as to close a corresponding clamping ring. A pair of frame plates is mutually parallel and is arranged below a cover of the metal piece along the length direction of the metal piece; and the other tail end of each semi-ring is connected to a corresponding frame plate, so that the movement of one frame plate relative to the other frame plate can influence the opening of the clamping ring. A plate handle for a binder clamp user to operate can move one frame plate relative to the other fixed frame plate. The frame plate longitudinally moves along the metal piece, and the interlocked ends of the semi-rings are separated so as to open the clamping ring. Two ends of a spring are fixed on opposite side walls of the bottom surface of the cover positioned below the frame plates respectively, and once the interlocked ends of the semi-rings are separated, the spring applies a pivoting force on the frame plates so as to pivot the frame plates in the opening direction of the clamping ring.

Secondly at first, the present invention can make people more easily open " twistlock " metalwork, and, the present invention can prevent that clamp ring is because of aforesaid former thereby by mistake or unexpectedly opened simultaneously effectively.
With reference to the accompanying drawings, clamp ring metalwork 10 disclosed in this invention is installed on the spine S place of a loose-leaf binder B, is used for preserving perforation paper or analog.It will be understood by those skilled in the art that described clamp ring metalwork 10 can adopt other modes and is installed on the dissimilar loose-leaf binders.Clamp ring metalwork 10 is one " twistlock " metalwork, and it has a plurality of common clamp rings of representing with Reference numeral 12,14,16.Certainly, more or less clamp ring is set on the clamp ring metalwork, does not all deviate from scope of the present invention.Each is made up of each clamp ring two semi-ring 12a-12b, 14a-14b, 16a-16b.Ground well known in the art, the outer end of twistlock formula clamp ring forms certain shape, so that it can interlocking when clamp ring is closed, this is able to best the embodiment in such as accompanying drawings such as Fig. 6, Fig. 8 and Figure 13.
Shown in Fig. 8～11, an end 12c, 12d, 14c, 14d and 16c, the 16d of each semi-ring is fixed on the frame plate 18,20, and described frame plate is for roughly waiting rectangle thin plate that is set parallel to each other of being longer than described annular metalwork.One cover cap 22 is installed on the described frame plate, and makes described frame plate be arranged at the below of described cover cap.Described cover cap is formed with opening 24a, 24b, passes and protrudes from the described cover cap for the top of described semi-ring.With reference to shown in Figure 10 and hereinafter described, described opening 24b is wider than described opening 24a.Importantly, different with other clamp ring metalworks, cover cap 22 adopts the conventional cover material preparation.Yet the material that is used to make cover cap 22 does not have the crimpness that is similar to spring of traditional clamp ring metalwork cover cap, that is to say that described cover cap does not possess enough elasticity to serve as the spring that described frame plate 18,20 is applied active force.
One end of clamp ring metalwork 10 is provided with a plate handle 26, and it is connected in frame plate 18,20 and opens and closes loose-leaf binder B for the user.Thus, described plate handle device includes a wind spring 27 and a crow bar 28, and the described frame plate 20 of push-and-pull vertically moves with respect to described cover cap 22 and frame plate 18 but this crow bar 28 is connected in described frame plate 20.Importantly, plate handle 26 is not connected with frame plate 18, so that can vertically move described frame plate with respect to clamp ring metalwork 10 under cover cap 22.So as mentioned below, when two frame plate pivot and cause opening or during closing motion, having only frame plate 20 linear or vertically move of described semi-ring, and frame plate 18 keeps motionless.For realizing this purpose, shown in Fig. 9 B, described frame plate 18 is longer than described frame plate 20, that is to say, lengthening frame plate 18 is so that this frame plate is adjacent to an end wall 23 of cover cap 22, and this end wall 23 is with respect to the plate pommel of described clamp ring metalwork.
Those skilled in the art will appreciate that opening clamp ring 12,14,16 includes two steps.At first, the interlocking end of described semi-ring is separated from each other certain distance; Then, rotate the semi-ring of each clamp ring and make it separated from one another.Plate handle 26 at first vertically moves frame plate 20 along clamp ring metalwork 10, makes its below along cover cap 22 slide a bit of distance.At this, frame plate 18 is regarded a fixing frame plate as, and in the operating process of plate handle 26, it can not vertically move this frame plate 18 along described clamp ring metalwork significantly.Yet the rotation of plate handle 26 but can vertically move frame plate 20 significantly.With reference to Figure 12, this moves with mark d represents, for example says 1/8 ".As shown in figure 12, this moves is enough to semi-ring 16b is removed certain distance, and the interlocking end of these parts is separated with the interlocking end of corresponding semi-ring 16a.In like manner, each semi-ring 12b also removes identical distance with 14b, and the interlocking end that makes these parts is separated with the interlocking end of corresponding semi-ring 12a and 14a respectively.
The interlocking end that only vertically moves described semi-ring that those skilled in the art will appreciate that frame plate 20 is separated from each other.Those skilled in the art is appreciated that also people can make it vertically separate with corresponding semi-ring 12a, 14a or 16a by among manual mobile semi-ring 12b, 14b or the 16b, and obtains identical effect.
In the operating process, in case frame plate 20 vertically moves with respect to frame plate 18 and the interlocking end of each clamp ring is separated from each other, each spring 30a～30c apply an active force on described frame plate so that described frame plate pivot towards the opening direction of clamp ring, the rotation of described frame plate and then cause the outer end of described semi-ring separated from one another, thus loose-leaf binder opened.
With reference to Figure 12～15, be formed with a tongue piece 50 downwards from the bottom surface of cover cap 22.Upper surface at described cover cap cuts out one folding piece, and the pushing its top from described cover cap is extended downwards, thereby form described tongue piece.Perhaps, this tongue piece also can be designed as an individual components that is fixed in the bottom surface of described cover cap and extends from this bottom surface downwards.As shown in drawings, in any case described tongue piece all forms or is fixed in the position of closing on clamp ring.Be appreciated that ground, each clamp ring all adjoins and is provided with a tongue piece 50 independently.Described tongue piece all forms (or fixing) in the side place corresponding to frame plate 20 tops of described cover cap.All be formed with a notch 52 corresponding to each tongue piece 50 position straight on the frame plate 20, as shown in figure 14, when described frame plate pivots and opens described clamp ring, the tongue piece that is formed on the frame plate runs through corresponding notch 52.
So as long as described clamp ring is in open mode, the tongue piece 50 of inserting in the notch 52 can stop vertically moving of frame plate 20, thereby makes clamp ring metalwork 10 remain on the state that clamp ring is opened.When closed clamp ring subsequently, described frame plate is rotated in the opposite direction towards the side with the Unscrew clamp ring.Yet in most of process of described frame plate rotation, the part of tongue piece 50 will can continue to stop vertically moving of frame plate 20 through described notch 52, this means that frame plate 20 can only continue to pivot and can't longitudinally-moving.Yet in the interlocking end of each semi-ring docked each other, frame plate 20 broke away from tongue pieces 50, and made the direction that frame plate 20 can fasten each other along the interlocking end of described semi-ring and vertically move, and closed loose-leaf binder B.
Next, as shown in figure 15, in another embodiment of the present invention, a tongue piece 60 is formed at or is fixed in the nearly semi-ring 16a place of frame plate 20.One notch 62 is formed on the cover cap 22, can stretch into this notch 62 so that described tongue piece 60 pivots in described frame plate 18,20 when opening described clamp ring.Be appreciated that ground, be adjacent to each clamp ring place and be provided with a tongue piece 60 independently, and the position that is adjacent to each tongue piece 60 on the cover cap 22 all is formed with a notch 62, so, when opening described clamp ring when described frame plate pivot, tongue piece 60 is respectively in the corresponding notch 62 that is formed on the cover cap 22.
Structure as shown in figure 14 is the same, the structure of described tongue piece 60/ notch 62 shown in Figure 15 is as follows, as long as described clamp ring is in open mode, the tongue piece 60 that is arranged in notch 62 can stop vertically moving of frame plate 20, makes clamp ring metalwork 10 remain on the state that clamp ring is opened.When described frame plate is rotated towards the direction of closing clamp ring, in most of process of described frame plate rotation, the part of tongue piece 60 will be through described notch 62 and stop vertically moving of frame plate 20, this means that described frame plate can only continue to pivot and can't longitudinal sliding motion.Yet in the interlocking end of each semi-ring docked each other, tongue piece 60 breaks away from notches 62 so that the direction that frame plate 20 can fasten each other along the interlocking end of described semi-ring and vertically moving, and closes loose-leaf binder B.
At last, with reference to Figure 11, in another embodiment of the present invention, described spring 30a～30c is substituted by ring spring 60a～60c.These springs no longer are fixed on the hangers 32 of described cover cap 22 inboards, but are wound between the tab 36 of the tab 34 of described frame plate 18 and described frame plate 20.Described spring 60a～60c role is same as described spring 30a～30c, the interlocking end of described clamp ring is separated, described spring forces described frame plate to pivot towards the direction that the outer end of semi-ring is separated from one another, and opens loose-leaf binder.
With regard to the whole enforcement of loose-leaf binder B, the loose-leaf binder that said structure provides a kind of interlocking design by clamp ring to make clamp ring can pin playback well and can not opened unintentionally when closure.So, even loose-leaf binder is under collision or being subjected to than big external force effect situation, described clamp ring still can remain on closed position of pinning and can not open.Further, in case clamp ring be opened, its can remain on always open mode until the user determine closed they.
In sum, some purposes of the present invention as can be seen and advantage all realize, and have reached other beneficial effect.
