The specific embodiment

Fig. 1 is the exploded view of a kind of clasp loose-leaf binder mechanism of the present invention, and this mechanism represents with Reference numeral 100 generally.This mechanism 100 comprises the steel upper shell 102 of substantially rigid, and this shell 102 supports a pair of steel support plate 104.In usual manner, described a pair of support plate 104 is provided with like this, and promptly they can relative to each other move pivotally, thereby allows to be mounted to steel semi-ring 106a, the 106b open and close as required on the described support plate 104.Each vertical end at clasp loose-leaf binder mechanism 100 is provided with a hole 101, a fixture can be admitted in this hole, such as rivet or screw, be used for described clasp loose-leaf binder mechanism 100 is fixed to article such as plastics or cardboard strip of paper used for sealing, to constitute a clasp loose-leaf binder.

As shown in Figure 1, in order further to strengthen described upper case, at the roughly mid portion of upper case 102 protuberance 108 is set, this protuberance 108 extends above the master curve of upper case 102 a little.Be provided with an elongated slot 110 along this protuberance 108, elongated slot 110 stretches along the longitudinal axis of upper case 102.This groove 110 allows a lever 120 to pass it and rotates with respect to it, will be described in detail lever 120 below.

Fig. 2 A and 2B show the detailed structure of lever 120.Lever 120 comprises that one is fixed to the handle 122 on the body 124 so that can move simultaneously.When this handle 122 was formed from steel, its far-end away from body 124 was enclosed within the plastic sheath 126, so that provide comfortable when using.Body 124 comprises that one has the core 128 in two holes 130, each hole 130 is used to hold a toe 132 of described handle 122 lower ends, and after toe 132 was accommodated in the hole 130, toe 132 was deformed, such as being stamped, so that handle 122 is fixed on the body 124 to form described lever 120.Each side of contiguous described core 128 is provided with an alar part 134, and alar part 134 outwards and downwards extends into a fingers 136.Neck 138 divides 128 to extend and end at a lug 148 from central division downwards, and this lug 148 is wideer than neck 138, and deviates from handle 122 embowments.Downside at described core 128 is two bases 129.The effect of lever 120 will be described in detail below.

Return Fig. 1, can see, be respectively equipped with a rectangular recess 140 along the inner side edge separately 142 of each support plate 104.When two support plates 104 correctly connected each other, two grooves 140 are common to form the neck 138 that a hole is used to hold the core 128 of described body 124.When neck 138 is contained in the hole that is formed by two grooves 140 like this, body 124 is connected with plate 104 and can moves with respect to plate 104, and described handle 122 is stretched the elongated slot 110 that passes on the upper case 102 in order to carry out rotational motion with respect to shell 102 around an axis with the longitudinal axis approximate vertical of shell 102.In addition, be respectively equipped with a rectangular slits 146, in order to the fingers 136 of the alar part separately 134 of the body 124 of admitting described lever 120 along the outer side edges separately 144 of each support plate 104.Adopt this structure, lever 120 is kept to relatively move by plate 104, and this will be described below.

Fig. 3 A to 3E illustrates the clasp loose-leaf binder mechanism 100 that is in ring closure and locking state.At this state, the handle 122 of lever 120 tilts to semi-ring 106a.Can be more clearly visible in Fig. 3 D and 3E, fingers 136 extends through otch 146 and below plate 104, lug 148 is also below plate 104, shown in Fig. 3 E.Described core has the top edge 150 of an arc, and the radian of this top edge 150 is approaching consistent with the curvature of protuberance 108 inner surfaces of upper case 102.When lever 120 was in this position, core 128 was with regard to perpendicular, and described arc top edge 150 is in abutting connection with the inner surface of the protuberance 108 of described shell 102.At this state,, can prevent that also plate 104 from upwards pivoting, shown in Fig. 3 E even there is the people to attempt to draw back ring 106a, 106b.Thereby described

ring

106a, 106b are locked and open

ring

106a, 106b to forbid any pivotal action.

Referring to Fig. 4 A to 4E, illustrate and be in the closed and clasp loose-leaf binder mechanism 100 of locking state not of ring.In this position, Fig. 4 A and 4D show clearer, and the core 128 of body 124 and alar part 134 tilt to ring 106b, and handle 122 extends upward generally, shown in Fig. 4 A.Can be more clearly visible in Fig. 4 E, described arc top edge 150 is spaced apart with the inner surface of the protuberance 108 of upper case 102.In this way, between lever 120 and plate 104, just there is one degree of freedom, like this, lever 120 just can rotate about 20 ° with respect to plate 104, and both do not taken shown in Fig. 3 A to Fig. 3 E and above-mentioned position, and not taking position shown in Fig. 5 A to Fig. 5 E yet, this will be described below.

When described lever 120 is in position shown in Fig. 4 A to 4E, described

ring

106a or 106b are not locked, be that they can be pulled outwardly out so that plate 104 upwards pivots, so that plate 104 arrives a stable state, their upper surface is facing to an angle that surpasses 180 °.As selection, described lever 120 also can pivot to semi-ring 106b, and like this, lug 148 and fingers 136 will act on the lower surface of described plate 104, opens stable state under the situation thereby arrive identical ring with pivot plate 104, shown in Fig. 5 A to Fig. 5 E.

Shown in Fig. 5 A to Fig. 5 E, as described semi-ring 106a, when 106b is opened, the handle 122 of lever 120 tilts to semi-ring 106b.Described

semi-ring

106a, 106b can be closed by pushing to each other, so plate 104 will be pivoted to the stable state shown in Fig. 3 A to Fig. 3 E from the stable state shown in Fig. 5 A to Fig. 5 E, wherein the upper surface of plate 104 is facing to an angle less than 180 °.As selection, the handle 122 of lever 120 also can pivot to semi-ring 106a, thereby the bottom 129 of the core 128 of lever 120 will act on the upper surface of plate 104, so that they are pivoted to the stable state shown in Fig. 3 A to Fig. 3 E, and closed described

semi-ring

106a, 106b.

Should be appreciated that above-mentioned be only used for the explanation can realize example of the present invention, can carry out multiple modification and/or selection to it, and not deviate from spirit of the present invention.Should also be understood that some feature of the present invention, promptly in order succinctly, in fact also to be separated to provide or carry out any suitable recombinant in the feature described in the content of unique embodiment.
