The specific embodiment

With reference to accompanying drawing, Fig. 1-4 especially, the circular clip mechanism of prior art are substantially with label 3 expressions.Circular clip mechanism 3 can any suitable method be fixed on thin skin (not shown) or some other substrate such as on the file.

Shown in Fig. 1-4, circular clip mechanism 3 comprises the thin-long casing 10 that is formed by upper shell 11 and lower house 12, and last lower house is respectively an arc-shaped cross-section substantially.Housing 10 supports two similar substantially actuating handles (respectively by label 13 expressions) and a plurality of ring (respectively by label 15 expressions).Each actuating handle 13 is installed in the housing 10 pivotally, is positioned at relatively vertically end substantially, with control loop 15 moving between closing position and open position.As shown in the figure, ring 15 is only opened in actuating handle 13 operations.But actuating handle 13 can be configured to the open and close ring.

Preferably shown in Fig. 1,3 and 4, the whole length of extensional shell 10 substantially along bending base 19 that each longitudinal edge of upper shell 11 forms, and from one vertically hold another vertically end cooperate with lower house 12 and support lower house 12 rigidly.Notch 23 is provided with along two bending bases 19.Notch 23 laterally relatively is provided with in pairs, and every pair of reception can be displaced sideways each ring at housing 10, with open and close by its one of passing ring 15.

Each ring 15 comprises two ring components 29, and ring component 29 is supported by housing 10, so as relative to each other open and closing position between move.In closing position, ring component 29 forms continuous closed hoop or loop keeping the loose leaf paper (not shown), and allows page to move to another ring component along ring 15 from a ring component 29.At open position, ring component 29 forms the discontinuous loop of opening, to increase or the taking-up page.Ring component 29 is formed by stainless existing cylindrical bar.Each ring two ring component 29 of 15 is installed on of pair of hinge plates 31 (only partly showing among Fig. 3) relative to one another, and passes respective slot 23.Articulated slab 31 be respectively approach with elongated, have vertically end of inside and outside longitudinal edge and two, and work with known manner.

With reference to Fig. 3, articulated slab 31 interconnects along their interior longitudinal edge with being arranged in parallel, forms to have the center hinge of pivot axis.Lower house 12 receives the outer longitudinal edge of interconnective articulated slab 31 loosely.Therefore, articulated slab 31 is maintained in the lower house 12, and outer longitudinal edge can move freely simultaneously.Corresponding opening 33 size and dimensions of the articulated slab 31 that adjoins are chosen to interact with actuating handle 13, to keep the position of actuating handle.

When articulated slab was in co-planar locations (that is, the angle between the outer surface of articulated slab is 180 °), lower house 12 was narrower slightly than the articulated slab that connects.When pivoting by this position with convenient articulated slab 31, they make 12 distortion of elasticity lower house and produce in housing and promote the elastic force of articulated slab 31 pivots away from co-planar locations, with closed hoop parts 29 (promptly, move pivot axis downwards and away from the housing upper surface) or open their (that is, upwards and towards the upper surface of housing moving pivot axis).And when ring component 29 closures, elastic force stops articulated slab to move and ring component is clipped together.Therefore, illustrated embodiment adopts existing structure mobile hinge fishplate bar 31 and ring component 29.

As shown in Figure 3, two actuating handles 13 comprise the head 43 of relatively flat respectively, and head 43 extends upward above upper shell 11 substantially, so that grasping and pivot actuating handle.Each actuating handle 13 also comprises two lateral arms 45 and cam structure 47.Lateral arms 45 outwards extends laterally from the opposite side of each actuating handle 13 below smooth head 43.The outward flange 46 of each in two lateral arms 45 of each actuating handle 13 is positioned on the inner surface of lower house 12, and thereby between actuating handle and lower house, only provide the line that is parallel to the housing longitudinal axis to contact, when actuating handle is moved to open or during closed hoop, can make actuating handle moving from a side to opposite side in housing unfriendly, the result can influence the proper operation of circular clip mechanism.

Referring now to the utility model preferred embodiment shown in Fig. 5-15, circular clip mechanism is substantially with label 50 expression, and similar with the circular clip mechanism of prior art aspect a lot.Circular clip mechanism 50 is formed with upper shell 52 and lower house 54, and last lower house has arc-shaped cross-section (with reference to Figure 10) substantially respectively.Upper shell 52 has core and open bottom.Lower house 54 is assembled together with upper shell 52, makes the open bottom of upper shell 52 be closed substantially, and upper shell 52 and lower house 54 limit the space between them.Upper shell 52 and lower house 54 support two similar substantially actuating handles 56 and a plurality of ring 58.Each actuating handle 56 is installed in upper shell 52 and the lower house 54 pivotally, is arranged in housing substantially and relatively vertically holds on corresponding one, with control loop 58 moving between closing position and open position.The part of actuating handle 56 is contained in the space of upper shell 52 and lower house 54 qualifications.The same with the circular clip mechanism 3 of prior art, the whole length of extensional shell 10 substantially along bending base 60 that each longitudinal edge of upper shell 52 forms, and vertically hold another vertically corresponding limit 61 cooperations and support lower house 54 rigidly on end and the lower house 54 from one.Notch 62 is provided with along two bending bases 60.Lower house 54 has the notch 63 of aligning. Notch 62,63 arranges in pairs relatively that laterally every pair of reception can be displaced sideways each ring at upper shell 52 and lower house 54, with open and close by its one of passing ring 58.

Each ring 58 comprises two ring components 64 and 66, and ring component 64 and 66 is supported by upper shell 52 and lower house 54, so as relative to each other open and closing position between move.In closing position, ring component 64 and 66 forms continuous closed hoop or loop keeping loose leaf paper, and allows page to move to another ring component (referring to Figure 13) along ring 58 from a ring component 29, and the circular clip mechanism of aforesaid prior art is the same.At open position, ring component 64 and 66 forms the discontinuous loop of opening, to increase or taking-up page (referring to Figure 15).Can imagine that ring component is formed by the existing cylindrical bar such as stainless suitable material, but the ring component of other suitable material and shape is thought also and is fallen in the scope of the present utility model.Two ring components 64 of each ring 58 and 66 are installed on of pair of hinge plates 68 (referring to Fig. 9) relative to one another.Articulated slab 68 be respectively approach with elongated, have vertically end of inside and outside longitudinal edge and two, and work with known manner.

As prior art, articulated slab 68 interconnects along their interior longitudinal edge with being arranged in parallel, forms to have the center hinge of pivot axis.In the space that articulated slab 68 forms between upper shell 52 and lower house 54.Lower house 54 receives the outer longitudinal edge of interconnective articulated slab 68 loosely.Therefore, articulated slab is maintained in the lower house 54, and their outer longitudinal edge can move freely with respect to lower house simultaneously.Hole 70 is near each vertically end formation of each articulated slab 68.Hole 70 interacts mode and the actuating handle of describing in detail 56 with following.

When articulated slab was in co-planar locations (that is, the angle between the outer surface of articulated slab is 180 °), lower house 54 was narrower slightly than the articulated slab 68 that connects.When pivoting by this position with convenient articulated slab 68, they make 54 distortion of elasticity lower house and produce in housing and promote the elastic force of articulated slab 68 pivots away from co-planar locations, with closed hoop parts 64 and 66 (promptly, move pivot axis downwards and away from the housing upper surface) or open their (that is, upwards and towards the upper surface of housing moving pivot axis).And when ring component 64 and 66 closures, elastic force stops articulated slab to move and ring component is clipped together.When ring component 64 and 66 was opened, elastic force made them keep separating.Therefore, illustrated embodiment adopts existing structure mobile hinge fishplate bar 68 and ring component 64 and 66.What however, it should be understood that is that retaining ring parts 64 and 66 are opened or closed alternate manner also falls into the utility model scope.

As shown in Figure 9, two actuating handles 56 comprise the head 72 of relatively flat respectively, and head 72 extends upward (referring to Fig. 6) substantially above upper shell 52, so that grasping and pivot actuating handle.In the embodiment shown, head is bent towards the orientation of level a little more at its free ora terminalis.Each actuating handle 56 also comprises two lateral arms 74 and cam structure 76.The lateral arms 74 of each actuating handle 56 stretches out and is placed in the respective aperture 70 of articulated slab 68 from the opposite side of each actuating handle 56 below smooth head 72.When actuating handle 56 was pivoted, the upper surface 78 of cam structure 76 cooperated (Figure 11) with the following joining edge of the articulated slab between hole 70 68 substantially, forces them to move up and encircles 58 to open.

For example shown in Fig. 9 and 11, supporting construction 80 is formed near each vertical end of lower house 54.Because lower house 54 is preferably made by steel plate, supporting construction 80 can be stamped to form in the same Sheet Metal Forming Technology of the remainder that forms lower house 54, although also can adopt other method that forms supporting construction 80.Figure 11 has shown the supporting construction 80 that forms by punching press lower house 54 best, and supporting construction 80 is for protruding and have the circular arc of a smooth stayed surface 83 from lower house 54.When circular clip mechanism 50 was assembled, supporting construction 80 was alignd with each actuating handle 56 and is provided horizontal support for each actuating handle 56.Preferably shown in Figure 10 and 11, each supporting construction 80 cooperates with the lower surface 82 (pivoting portions) of actuating handle 56, lower surface 82 comprises the lower surface of two lateral arms 74 and cam structure 76, so that the support that cooperates width of crossing between actuating handle 56 and the supporting construction 80 to be provided.The stayed surface 83 of the supporting construction 80 that cooperates with lateral arms 74 and cam structure 76 crosses lower house 54 and extends to form string between on the lower house cross section circular arc 2.Different with the above-mentioned prior-art devices of having only the actuating handle outward flange to cooperate with the lower house arcwall, x wire contact operation for actuating handle when actuating handle pivots of crossing the actuating handle width provides stability.

Shown alternate embodiment in Figure 16-18, wherein the parts except following and the foregoing description is identical.In this embodiment, supporting construction 80 comprises a pair of protuberance 80a and the 80b that protrudes from lower house 54, form certain intervals between protuberance 80a and the 80b, the upper surface of protuberance 80a and 80b constitutes planar support surface 81a and the 81b that is on the same horizontal plane, and the string alignment between on the lower house cross section circular arc 2.The a pair of protuberance 80a of supporting construction 80 and the stayed surface 81a of 80b and 81b cooperate with the respective lower of two lateral arms 74, so that provide support for cooperating between actuating handle 56 and the supporting construction 80a.Therefore, unique difference of this embodiment and the foregoing description is, the actuating handle 56 of this embodiment is only supported on their lateral arms 74, and not supported on cam structure 76, but this structure still provides more stable support than above-mentioned one type of prior art syringe.

From first embodiment of position operation shown in Figure 10 and 11 time, the head 72 of actuating handle 56 can be by grasping and outwards and is downwards pivoted.The lower surface 82 of each actuating handle 56 comprises that the lower surface of lateral arms 74 and cam structure 76 pivots on supporting construction 80, the whole width along actuating handle 56 cooperates with supporting construction substantially.The upper surface 78 of cam structure 76 upwards pushes away articulated slab 68, and the elastic force that causes them to overcome lower house 54 upwards pivots.When actuating handle 56 pivoted, the free end of lateral arms 74 slid through respective aperture 70, made the pivoting action of actuating handle 56 not be subjected to the influence that cooperates of lateral arms and articulated slab.But hole 70 prevents actuating handle 56 with respect to articulated slab 68 axial and transverse movements, thereby keeps the appropriate location of actuating handle.Make articulated slab upwards by their co-planar locations in case actuating handle 56 upwards pivots, the elastic force of lower house 54 fully moves up articulated slab.When articulated slab 68 moved, the ring component of each ring 58 was opened in 64,66 minutes, the position that final arrival is opened fully.For closed hoop parts 64,66, ring component can manually be pushed away together.But, under the situation that does not break away from the utility model scope, can use the mode of other closed hoop parts.The operation of second embodiment is identical with the operation of first embodiment substantially, except cam structure 76 by above being suspended on lower house in the lateral arms 74 of rotating on stayed surface 81a and the 81b.

The assembly of mechanism of the present utility model is preferably made by suitable rigid material such as metal (for example steel).But do not break away from scope of the present utility model by the nonmetal mechanism that comprises that especially plastics are made yet.In addition, not the direct supporting construction of punching press from the lower house, for example the supporting construction that is connected on the lower house by known manner does not break away from scope of the present utility model yet.

When introducing the element of the utility model or most preferred embodiment, article " ", " being somebody's turn to do " and " described " means that one or more elements are arranged.Term " comprises " that " comprising " and " having " is meant to comprise and mean also have other parts except components listed.In addition, this is employed " on ", the distortion of D score and these terms just for convenience, and need not the concrete arbitrarily location of element.

Because above-mentioned various distortion all can be made not breaking away under the utility model scope, therefore above literal and all the elements shown in the drawings all should regard a kind of as and schematically and not should regard a kind of restriction as.
