Device 100 comprises have three link members lever assembly of (being action bars 114, intermediate bar 116 and connecting rod 118).Action bars 114 has freely first vertically holds 114a, and sheath 120 (this sheath 120 can be by soft relatively material, and for example rubber or soft plastic material are made) cooperates with this first vertical end 114a, to increase the comfortableness of using.Second of action bars 114 vertically holds 114b vertically to hold 116a to cooperate pivotly by rivet 122 with first of intermediate bar 116.Second of intermediate bar 116 vertically holds 116b to cooperate pivotly with connecting rod 118 by rivet 124.

Lug 126 substantially perpendicularly extends upward from base 102.Lug 126 is preferably integrally formed with base 102, for example is stamped to form from base 102.Lug 126 has hole 128, and this hole 128 has central longitudinal axis.As seen from Figure 1, action bars 114 cooperates with lug 126 pivotly by rivet 130.Especially, in the hole 132 of the hole 128 of rivet 130 insertion lugs 126 and action bars 114.By such arrangement, action bars 114 can center on the central longitudinal axis pivoting action in the hole 128 of lug 126 with respect to the remainder of base 102 and device 100.Spring 134 also cooperates with lug 126 by rivet 130.The following free end of spring 134 in abutting connection with and act on base 102, the last free end of spring 134 cooperates with action bars 114 by extension 136 and acts on action bars 114.By such arrangement, action bars 114 vertically hold freely 114a by spring 134 away from base 102 bias voltages.

Connecting rod 118 cooperates with revolving part 138 by middle dog collar 140.At first referring to revolving part 138, this revolving part 138 has smooth panel 142 and the functional unit 144 that is generally triangular, and described panel 142 and functional unit 144 are integrally formed each other, are for example formed by plastic material.As seen, the functional unit 144 of revolving part 138 has three ledges 146 and three intermediate recess zones 148.Three ledges 146 center on the central longitudinal axis equal angles ground setting of functional unit 144, and promptly they are spaced apart from each other with 120 °.Similarly, three sunk areas 148 also are provided with around the central longitudinal axis equal angles ground of functional unit 144.

The functional unit 144 of revolving part 138 has three grooves 150, and each groove 150 is used to hold corresponding spring 152.Spring 152 away from the vertical end of groove 150 the corresponding finger 154 of radially extending, with away from revolving part 138 and towards connecting rod 118 bias voltage dog collars 140 in abutting connection with middle dog collar 140.Finger 154 is provided with around the central longitudinal axis equal angles ground of dog collar 140, and promptly they are spaced apart from each other with 120 °.The finger 154 of dog collar 140 also is contained in the groove 150 of revolving part 138 to rotatablely move simultaneously.

Middle dog collar 140 has three leg-of-mutton claws 156, and this claw 156 extends axially towards connecting rod 118.Each claw 156 has straight flange and contiguous hypotenuse, and described straight flange extends axially towards connecting rod 118.Claw 156 also is provided with around the central longitudinal axis equal angles ground of dog collar 140, and promptly they are spaced apart from each other with 120 °.In addition, the finger 154 of ring 140 and claw 156 are provided with around the common equal angles of the central longitudinal axis of dog collar 140 ground, be that each finger 154 is spaced apart with 60 ° with the claw 156 of its vicinity, similarly, each claw 156 is spaced apart with 60 ° with the finger 154 of its vicinity.

Connecting rod 118 has the basic circular plate 160 that is, described plate 160 has six and is the hole 162 of rectangle substantially, and described hole 162 is provided with around the central longitudinal axis equal angles of plate 160, and promptly each hole 162 is spaced apart with 60 ° with contiguous hole 162.The size in hole 162 and shape are set to and can receive dog collar 140 corresponding claws 156 by it.Because the setting of the setting in the hole 162 of the plate 160 of connecting rod 118 and the claw 156 of dog collar 140, when device 100 suitably assembled, all three claws 156 all were contained in the plate 160 corresponding holes 162.

Gripper shoe 164 substantially vertically extends upward from base 102.Gripper shoe 164 is preferably integrally formed with base 102, for example is stamped to form from base 102.Gripper shoe 164 has hole 166, and rivet 168 inserts these holes 166 with fixedly revolving part 138, dog collar 140 and connecting rod 118, thereby they can be rotated or gyration around common central longitudinal axis L-L (same see Fig. 2).

As seen, the axis L-L that centered on of revolving part 138, dog collar 140 and connecting rod 118 rotations or revolution is different with the axis that action bars 114 pivots are centered on.In addition, compare with the axis that action bars 114 pivots are centered on, axis L-L is more away from base 102.

Fig. 3 is to Figure 9 shows that the paper-retaining device 100 that is in the ring open mode, and its hogging part 106 is positioned at the ring open position, promptly encircle part 106 break away from the cooperation of column piece 104 with contact.In this ring open mode, the part 108a that the center of intermediate bar 108 is bent upwards is contained in one of them sunk area 148 of functional unit 144 of revolving part 138 (for purpose is clearly represented with dotted line in Fig. 3 and Fig. 8).In this ring open mode, the action bars 114 of lever assembly is positioned at its stable upper position, and quilt is towards this upper position bias voltage.To action bars 114 excessive bias voltages, action bars 114 has stop part 168 for fear of spring 134 or external force, and when action bars 114 was positioned at its stable upper position, stop part 168 was in abutting connection with revolving part 138.

When action bars 114 downward (that is, the direction shown in the arrow S in Fig. 3) moved pivotally, it caused connecting rod 118 rotatablely moving accordingly along equidirectional (promptly along the direction shown in the arrow R among Fig. 3).Because the shape of the claw 156 of dog collar 140, connecting rod 118 is connected with dog collar 140, makes to rotatablely move in connecting rod 118 rotation on this direction causing dog collar 140 equal angular in the same direction.Because cooperating between dog collar 140 and the revolving part 138, the rotation of dog collar 140 causes rotatablely moving accordingly of revolving part 138 equal angular in the same direction successively.

When action bars 114 when its stable upper position is pivoted to position, its underpart (as Figure 10 to shown in Figure 11), 60 ° of revolving part 138 rotations, so that the center of the ledge 146 of the functional unit 144 of revolving part 138 extruding intermediate bars 108 be bent upwards part 108a, and overcome the biasing force that reed 112 makes progress.By such action, arch part 106 is pivoted to the ring closed position, closely cooperates to close two rings with column piece 104 at this ring closed position arch part 106.

Lever assembly is designed to make that the pivoting angle of connecting rod 118 is the twice of the pivoting angle of action bars 114.In this specific embodiment, the rotational angle of action bars 114 between its stable upper position and position, its underpart is 30 °, feasible each downward pivoting action by action bars 114, connecting rod 118 (thereby dog collar 140 and revolving part 138) is along 60 ° of the direction shown in arrow R rotations, and this angle is the vicinity of functional unit 144 of revolving part 138 and the angle between ledge 146 that replaces and the sunk area 148.

As Figure 12 and shown in Figure 13, when the downward power of the action bars 114 that acts on lever assembly discharges, action bars 114 will return its stable upper position under the partial pressure of spring 134.In the upwards pivot motion course of action bars 114, will cause the rightabout rotation of connecting rod 118 along direction shown in arrow R among Fig. 3.

Yet, go back shape because of the claw 156 of dog collar 140, when the rightabout of connecting rod 118 edge directions shown in arrow R among Fig. 3 rotated, connecting rod 118 broke away from dog collar 140 and is connected.More particularly, connecting rod 118 will slip over the claw 156 of dog collar 140, and dog collar 140 is rotatablely moved simultaneously.Between this moving period, dog collar 140 is overcome the biasing force of spring 152 and pushes revolving part 138 to.In brief, dog collar 140 and revolving part 138 at connecting rod 118 along keeping static in the rightabout rotary movement of direction shown in the arrow R among Fig. 3.Thereby as seen, 140 of revolving part 138 and middle dog collars are along the rotation of the direction shown in the arrow R, and rotation in the opposite direction.

When action bars 114 arrived its upper stable position, it had rotated 30 °, this means that connecting rod 118 has rotated 60 °.In this position, each claw 156 is contained in the corresponding hole 162 of plate 160 of connecting rod 118 once more.

When action bars 114 is pivoted to position, its underpart downwards subsequently, connecting rod 118 is along the rotation of the direction shown in the arrow R among Fig. 3, thereby cause that dog collar 140 and the corresponding of revolving part 138 rotatablely move, make revolving part 138 contiguous sunk areas 148 cooperate with the part 108a that is bent upwards at intermediate bar 108 centers, thereby allow upwards pivoting action of reed 112, open ring with the arch part 106 that pivots away from column piece 104, install 100 thus and present the ring open mode, extremely shown in Figure 9 as Fig. 3.

As seen, paper-retaining device according to the present invention has the following advantages at least:

A. because the angle amplification characteristic of lever assembly, the user only need be with 30 ° of downward pivot action bars 114, thereby cause 60 ° rotation of revolving part 138, make device 100 operate easily like this;

B. compare with traditional device, the opening and closing of ring all are to be caused by the identical downward pivoting action of action bars 114 from its stable upper position, install 100 operation thereby simplified;

C. after each pivoting action downwards, action bars 114 returns its stable upper position to prepare operation next time under the partial pressure that spring 134 makes progress; And

Even d. when being in its stable upper position, action bars 114 is fully spaced apart with column piece 104 and arch part 106, thereby the paper that allows to be installed with the hole can take out or insert column piece 104 and the arch part 106 from column piece 104 and arch part 106.
