The specific embodiment
Accompanying drawing 1-14 has shown according to circular clip mechanism 100 of the present utility model.Circular clip mechanism 100 comprises housing 101, two annular elements 103, two articulated slabs 105 and control structures 107 substantially, and housing 101 is supporting control structure 107 and annular element 103 is installed on the articulated slab 105.As will be described below, described control structure 107 can be with respect to the rotation of described housing with closure and lock circular clip mechanism 100, thereby the maintenance loose leaf paper is perhaps opened circular clip mechanism 100 to increase loose leaf paper to annular element 103 or to take out loose leaf paper from annular element 103.
Be formed with the opening 115 that is used to lay control structure 107 on the flat top portion 109 of housing 101, opening 115 both sides are formed with the band protuberance 117 in the hole of alignment mutually.Control structure 107 can be by passing control structure 107 and protuberance 117 the pivot 119 in hole be pivotally mounted on the housing 101.Preferably, on housing 101, form opening 107 and protuberance 117 by die cut once-forming ground.In order to strengthen the intensity of housing 101, can on housing 101, form many ribs that cross housing 101, ribs preferably is formed on housing 101 by punching press.In addition, two longitudinal edge portions 111 of housing 101 also are formed with relative paired breach 121 mutually, are used to lay annular element 103.Should be understood that difform housing is as the housing of asymmetric shape and have varying number and the housing of shaped aperture or breach does not break away from scope of the present utility model equally.
Each annular element 103 comprises and is installed in two ring component 103a, 103b on the articulated slab 105 respectively.The cross section of ring component 103a, 103b is circular, and is made by the suitable metal such as steel etc.Because two articulated slabs 105 can move pivotally by means of the support that bends base 111a, thereby cause ring component 103a, 103b between closing position and open position, to move.In closing position, described ring component 103a, 103b have formed a basic continuous and closed loop to keep loose leaf paper and to allow loose leaf paper to move to another ring component along annular element 103 by a ring component.And when it was shown in an open position, each ring component had formed a discontinuous open loop that is suitable for increasing and decreasing page.Although described in an illustrated embodiment two ring components can move, ring component is movable, the Immobile mechanism of another ring component does not break away from scope of the present utility model.In addition, the number of ring does not break away from the utility model scope required for protection more than two and mechanism with closed hoop of difformity (for example two ring components all are semicircular in shape) yet.
As noted earlier, housing 101 support and control structures 107 make it with respect to housing 101 rotations.The control structure 107 of present embodiment comprises control lever 123 and cam part 125, and cam part 125 can be used for engaging with the inner surface (towards the surface of housing flat top portion 109) of articulated slab 105.In this embodiment, control lever 123 and cam part 125 form and are formed by the sheet metal bending, but they also can form dividually and fit together.As seen from Figure 8, cam part 125 is limited by two isolated cam bits 127 and forms.In order to reduce the friction between cam part 125 and the articulated slab 105, the plastic cushion (not shown) of correspondingly-shaped can be set between two isolated cam bits 127.
In according to circular clip mechanism of the present utility model, articulated slab 105 is arranged to angle α between the outer surface (surface that promptly deviates from the flat top portion 109 of housing 101) of two articulated slabs 105 always less than 180 °, and two articulated slabs 105 are in co-planar locations (promptly the angle α between the outer surface of two articulated slabs 105 is 180 ° position) never.In other words, no matter circular clip mechanism is in closed and locked state (Fig. 8) still is that circular clip mechanism is in open mode (Figure 14), and the angle α between the outer surface of two articulated slabs 105 (surface that promptly deviates from the flat top portion 109 of housing 101) is always less than 180 °.Because the width the when width of housing 101 flatly combines than two articulated slabs 105 is narrow slightly, therefore, the elastic force of housing 101 always makes the pivot axis of articulated slab 105 move up, be tending towards making articulated slab 105 to pivot opening ring component 103a, 103b, and can not make ring component 103a, 103b closure.
For circular clip mechanism is installed on the strip of paper used for sealing, each longitudinal end 113 at housing 101 is formed with installation portion 129, installation portion 129 is from the bottom water level land longitudinal extension of longitudinal end 113, the protrusion 129b that comprises par 129a substantially and be integral with par 129a and par 129a is surrounded.As shown in Figure 6, protrusion 129b preferably has U-shaped cross-section.On the 129a of par, be formed with one or more hole 129c, be used to make securing member to pass, thereby circular clip mechanism is installed on the strip of paper used for sealing from it.Alternatively, also can give prominence to a plurality of sharp-pointed portions from 129a bottom surface, par, be used to be inserted into strip of paper used for sealing, thereby need not to use other securing member just circular clip mechanism can be installed on the strip of paper used for sealing.
Need to prove that in the utility model accompanying drawing illustrated embodiment, the width of two articulated slabs of circular clip mechanism equates.When opening circular clip mechanism, articulated slab 105 movings range that this width equates equate, have limited the opening degree between the free end of ring component 103a and 103b to a certain extent.Preferably, the width of two articulated slabs 105 can be chosen to a broad, one narrower.At circular clip mechanism when closure state changes to open mode, the angular range that the angular range that narrower articulated slab 105 moves moves greater than the articulated slab 105 of broad, therefore, the ring component that is installed on the narrower articulated slab 105 can move the bigger scope that is opened to along with narrower articulated slab 105, make the interval between the free end of when opening ring component become big, be convenient to very much the access loose leaf paper.Preferably, be under the inequality or asymmetric situation at two ring components of each ring, relatively long ring component will be installed on the narrower articulated slab, and relatively short ring component will be installed on the articulated slab of broad.Adopt under the situation of different in width at two articulated slabs 105, housing 101 can adopt symmetric shape or adopt asymmetrical shape.
The operating process of described circular clip mechanism is described below in conjunction with accompanying drawing.Control structure 107 can optionally make circular clip mechanism 100 move to closed and locked position (shown in Fig. 1-8) and open position (shown in Figure 10-14).For closed annular clamp mechanism 100, the control lever 123 of the control structure of the circular clip mechanism of state is as shown in figure 10 rotated towards housing downwards, make the effect end of cam part 125 of control structure press two articulated slabs 105 downwards, under the effect of cam part 125, the pivot axis of articulated slab 105 moves down away from housing flat top portion 109, thereby the ring component 103a, the 103b that cause being installed on the articulated slab 105 are combined together to form closed hoop along with moving of articulated slab, to keep loose leaf paper.At closed and locked position, because the cam part 125 of control structure 107 still keeps being pressed against on the articulated slab 105, ring component 103a, 103b combine and can not throw off.At closed and locked position, the orientation of articulated slab 105 makes the angle α between its outer surface reach maximum, but still less than 180 °, as shown in Figure 8.
In order to open circular clip mechanism 100, the control lever 123 of the control structure of the circular clip mechanism of state is as shown in Figure 5 upwards rotated away from housing, make the cam part 125 of control structure break away from two articulated slabs 105, manually separate under ring component or the elastic force effect the operator at housing 101, the pivot axis of articulated slab 105 moves up towards housing flat top portion 109, thereby causes being installed in ring component 103a, 103b being moved apart along with articulated slab on the articulated slab 105.The elastic force of housing 101 makes ring component 103a, 103b stay open state, to increase or to take out loose leaf paper.At open position, the orientation of articulated slab 105 makes the angle α between its outer surface reach minimum, as shown in figure 14.
In according to circular clip mechanism 100 of the present utility model, because articulated slab 105 is arranged to angle α between the outer surface of two articulated slabs 105 always less than 180 °, the elastic force of housing 101 always is tending towards making the pivot axis of articulated slab 105 to move up towards housing flat top portion 109, thereby cause being installed in ring component 103a, 103b being moved apart on the articulated slab 105 along with articulated slab, therefore, simple in structure according to circular clip mechanism of the present utility model, be easy to make, thereby reduce cost greatly.
Because the installation portion 129 at the longitudinal end 113 of each housing 101 comprises the protrusion 129b that par 129a is surrounded, its structural strength strengthens greatly, can not be out of shape in the time of on the strip of paper used for sealing that this circular clip mechanism is installed to file or notebook, therefore, this circular clip mechanism can be installed on the strip of paper used for sealing of file or notebook securely.
Because it is narrower the width of two articulated slabs can be chosen to a broad, one, ring component can move the bigger scope that is opened to along with narrower articulated slab, make the interval between the free end of when opening ring component to become bigger relatively, be convenient to very much the access loose leaf paper.
The assembly of mechanism of the present utility model is by making such as the suitable hard material of metal (for example, steel).But do not break away from scope of the present utility model by the mechanism that the nonmetallic materials that specifically comprise plastics are made yet.
