Description
The present invention relates to a kind of clip that is used to clamp paper or similar articles.
Multiple traditional clip is arranged at present, for example, a kind of finger by the user acts on action bars and makes the open duplex clip of contact portion, a kind of jewel folder (gemclip) with bimetallic circle, or a kind of its have the bending clamping plate metal clip, it need just can install to the paper that piles up with a clip thrust unit (clip servicing unit) and get on.
Though compoundly accompany a bigger clamping force,, large-sized duplex clip needs bigger power just can open chuck.The situation that also has chuck not open sometimes.The all lamination paper of the cause of action bars when being placed on other the lamination paper, numerous sheet stack of being clamped by clip have trouble, because will loose off.Because the jewel folder only clamps paper between ring, its clamping force is too little so that can not clamp thicker numerous paper.
Though the metallic plate clip is more convenient, and have enough big clamping force, the other clip propulsion plant clip of neither one just can not use.
Therefore, the present patent application people has improved traditional clip, thereby does not need just can open and close with any propulsion plant the clamping plate of clip.
The purpose of this invention is to provide a kind of clip that need not servicing unit, it is easy to operation and can produces a strong clamping force.
To achieve these goals, clip of the present invention clamps numerous paper or similar articles between a pair of clamping plate, and this can strain to clamping plate, and clamping plate extend bendingly from the opposite end of the body portion with certain width of clip.This clip comprises:
One clip body of being made by the smaller elastomeric material of coefficient of elasticity is a chuck, this chuck comprises that one has the chuck base-body part and a pair of lower plate of going up of certain width, this diverges the bending extension of formula ground to clamping plate continuously from the opposite end of chuck base-body part, and each clamping plate has one to point to the chuck base-body part clamping part of bending inwardly at its end; And, one that make by the bigger elastomeric material of coefficient of elasticity, and to be contained in clip body slidably be gland on the chuck, this gland comprises a gland body portion and a pair of lower platen of going up, this is to opposite end continuously with the shrinking bending extension of pressing plate from the gland body portion, each pressing plate is assemblied on each clamping plate slidably, and the gap between the pressing plate end of gland is less than a maximal clearance between the clamping plate of chuck.When the pressing plate of gland slides on clamping plate or during the clamping plate that slip away terminal, the clamping part of clamping plate is done toward each other or the motion that is separated each other.
Each clamping plate of chuck are provided with several gathering sills.Each pressing plate of gland is provided with several suitable guiding projections that cooperates with each gathering sill.
The bending part of clamping plate in chuck two clamping plate exceeds certain distance forward than the bending part of another clamping plate.The clamping part that preferably has the bending part that exceeds forward is longer than another clamping part.
Preferably the opposite end at the gland body portion respectively is provided with a rib, and at the relative side of two clamping plate one rib is set respectively also.
Extend because the clamping part of chuck is made the fork formula towards the end of clamping plate, thereby numerous paper or similar articles can inject clip smoothly.
When gland is pulled on the chuck, when sliding, the pressing plate of gland presses clamping plate inwardly on clamping plate, make clamping plate closer to each other, this is because the insertion gap that forms between the pressing plate of gland is provided with than the little cause in maximal clearance that forms between the clamping plate at chuck.
At this moment, because the direction that the clamping part of the clamping plate of each chuck bends inwardly and bends is pointed to the chuck base-body part, this clamping part also has an elastic force.The thrust of gland adds above-mentioned elastic force, just can obtain a strong clamping force.In addition, because clamping part is in the bending of the direction of insertion of numerous paper or similar articles, this is the big resistance of generation one between two top surfaces of paper or similar articles and clamping part just, and it can stop paper or similar articles to withdraw from clip.
Because the clamping part of each clamping plate is from the end bending of clamping plate, and in the clamping part one towards the chuck base-body part indentation of chuck some, therefore just do not have clip and do not bite the thing of user's finger and take place.
Under the bigger situation of clip size, user's finger might be damaged in the both sides of the edge up and down of chuck or gland.Yet the finger of providing ribs just can protect the user for chuck or gland exempts from the injury of lateral edges.

(embodiment 1)
Fig. 1 (a) is the longitudinal sectional view of the present invention one clip A to 1 (c), and they show the relation when using between chuck 1 and the gland 4.Fig. 2 is the exploded perspective view of the clip A shown in Fig. 1, and Fig. 2 (a) shows chuck 1, and Fig. 2 (b) shows gland 4.Fig. 3 is the stereogram of clip A of the present invention, and it shows the situation when using.
Clip A of the present invention comprises chuck of being made by the smaller elastomeric material of coefficient of elasticity 1 and the gland of being made by the bigger elastomeric material of coefficient of elasticity 4.The coefficient of elasticity K here is by formula F=Kx definition, and wherein x is a shift length, and F is a power.
Chuck 1 and gland 4 are formed by dull and stereotyped a bending as metallic plate, synthetic resin board or suchlike material.Gland 4 is slidably mounted on the chuck 1, so that paper or similar articles can be clamped.
Shown in Fig. 2 (a), the dull and stereotyped chuck 1 that forms, chuck 1 comprise that chuck base-body part 2 that its width or height X are certain and a pair of opposite end from chuck base-body part 2 diverge the last lower plate 3,3 of formula ground bending continuously.In this embodiment, clamping plate 3,3 each have an end from clamping plate 3,3 to bend inwardly and overbending direction points to clamping part 3a, the 3a of chuck base-body part 2 at its end.Between the end of clamping part 3a, 3a, form one and insert gap Z.
Therefore, will be maximal clearance between the clamping plate 3,3 of present embodiment chuck 1 at a gap V who forms between bending part 3b, the 3b of connecting cleat 3,3 and clamping part 3a, 3a.In the position shown in Fig. 2 (a), the insertion gap Z that forms between the end of clamping part 3a, 3a is maximum.The width of chuck base-body part 2 or height X can change according to the thickness of stack paper B.
Shown in Fig. 2 (b), formed gland 4 by flat board, gland 4 comprises that a width or the certain gland body portion 5 of height X ' and a pair of opposite end from gland body portion 5 shrink the last lower platen 6,6 that bending forms continuously.The insertion gap Y that forms between the end of pressing plate 6,6 is narrower than the width X of the chuck base-body part 2 of chuck 1.It is narrower than the width X ' of the gland body portion 5 of gland 4 to insert gap Y.What should be noted is that above-mentioned size only is an example, the invention is not restricted to this size.Importantly inserting gap Y must be narrower than the maximal clearance V of chuck 1.For example, the insertion gap Z of the comparable chuck 1 of insertion gap Y is wide.
Above-mentioned size relationship can provide with following formula:
Insert gap Y＜width X＜insertion gap Z＜width V
Certainly, above-mentioned formula only is an example.Inserting gap Y can be littler than inserting gap Z, as long as it is little just more passable than width V to insert gap Y.
Cooperate with the clamping plate 3,3 of chuck 1 by pressing plate 6,6 that opens gland 4 and the end that makes pressing plate 6,6, gland 4 is slidably mounted on the chuck 1.When gland 4 slided into a final propelling position on chuck 1, clamping part 3a, the 3a of clamping plate 3,3 were approaching mutually.Perhaps, as will be below described in conjunction with Figure 5, when gland 4 during in final propelling position, clamping part 3a, 3a also can be in contact with one another.
Shown in Fig. 2 (a), respectively be provided with several gathering sills 7,7 (at two grooves shown in the illustrated embodiment) on the clamping plate 3,3 of chuck 1, respectively be provided with several on the pressing plate 6,6 of gland 4 and be suitable for the guiding projection 8,8 (at two projections shown in the illustrated embodiment) that cooperates with gathering sill 7,7, shown in Fig. 2 (b). Guiding projection 8,8 cooperates with gathering sill 7,7 respectively, makes projection 8,8 to slide on groove 7,7 and can releasing slots 7,7.Like this, gland 4 just is assembled on the chuck 1 slidably.
In this embodiment, gland 4 can be owing to accidentally just spinning off from chuck 1, because the guiding projection of gland 48,8 cooperates slidably with gathering sill 7,7 but can not throw off, and the width X of the chuck base-body part 2 of chuck 1 is bigger than the insertion gap Y between the pressing plate 6,6 of gland 4.
Although accompanying drawing does not illustrate, each pressing plate 6,6 can be provided with the prodger that one or more swallow-tail form is given prominence to part or other any desirable shapes on the surface within it.Gathering sill also can be the non-i.e. groove of groove that penetrates.
Below, in conjunction with Fig. 3 the example of use at the described clip of this embodiment is described.
Because clamping plate 3,3 are the extension of fork formula from chuck base-body part 2 to terminal (seeing Fig. 1 (a) and 1 (b)), so the insertion gap Z that forms between the clamping part 3a that paper or similar articles B can waltz through at clamping plate 3,3,3a end and inserting in the chuck 1.
When (using the direction shown in the arrow W among Fig. 3) when sliding forward on the clamping plate 3,3 of the chuck 1 that gland 4 is inserting paper B, the pressing plate 6,6 of gland 4 pushes away the clamping plate 3,3 of chuck 1 inwardly when sliding on clamping plate 3,3, make clamping plate 3,3 mutually near (reducing the distance of inserting gap Z), thereby between clamping part 3a, 3a, clamp paper B firmly.Because chuck 1 and gland 4 are made by elastomeric material, so clamping plate 3,3 can be clamped numerous paper firmly.
(see Fig. 1 (c) and Fig. 3), the thrust of the pressing plate 6,6 of the elastic restoring force of clamping part 3a, 3a and gland 4 can increase the clamping force to paper B when the pressing plate 6,6 of gland 4 makes the clamping part strain.In addition, under the thicker situation of numerous paper B, clamping part 3a, the 3a of clamping plate 3,3 at first are out of shape, thereby have suppressed the expansion of chuck 1 and gland 4.Stoped the loose of the paper that is stacked thus.
When paper B withdrawed from, gland 4 slided with an opposite direction on chuck 1, with the thrust of release action on clamping plate 3,3 (seeing Fig. 1 (b)) at clip A.When gland 4 is mobile backward, between the end face of paper B and clamping part 3a, 3a, produce a bigger resistance, because clamping part 3a, the 3a of clamping plate 3,3 are in the direction of insertion bending of paper B.Therefore, gland 4 can successfully slide on chuck 1, and the clamping plate 3,3 of chuck 1 must be opened.(embodiment 2)
Fig. 4 is the longitudinal sectional view of another embodiment of clip A of the present invention.Fig. 5 is the longitudinal sectional view of the clip A shown in Fig. 4, and it illustrates situation about at utmost cooperating between chuck 1 and the gland 4.Fig. 6 (a) and 6 (b) are about key diagram safe in utilization, and Fig. 6 (a) shows clip A of the present invention, and Fig. 6 (b) shows the clip of prior art.
In a second embodiment, as shown in Figure 4, among bending part 3b, the 3b of chuck 1 one (in the accompanying drawing top one) exceeds one forward than another bending part 3b (in the accompanying drawing following) and gives set a distance, and the clamping part 3a of bending part 3b in front (in the accompanying drawing top) (in the accompanying drawing top) grows than another clamping part 3a (in the accompanying drawing following).In such structure, as shown in Figure 5, when gland 4 slided into final propelling position on chuck 1, clamping part 3a, the 3a of chuck 1 clamping plate 3,3 were in contact with one another, thus bending each other.The position of each clamping part 3a, 3a when the free position of not contact is represented with double dot dash line in Fig. 5.
If two clamping part 3a, 3a are short, then elastic resistance becomes big.This can increase the restraining force to paper, but the advantage that it just can not utilize clamping part 3a, 3a strain to be had.Therefore, as shown in Figure 4, a clamping part 3a structure longer than another clamping part 3a can be utilized the advantage of two clamping part 3a, 3a simultaneously.
Because a direction of insertion indentation at paper B in the end of clamping part 3a, 3a, therefore, the end of paper B is easy to inject clip A.
Shown in Fig. 6 (a), contact with the end of clip A even user's finger is accidental, clip A can not bite finger yet.On the contrary, Fig. 6 (b) illustrates one and does not have the structure of the clip of above-mentioned condition.In this case, the end of the clamping plate of neither one indentation in the chuck 1 '.In a kind of like this structure, user's finger just might be bitten by the end of clip.(embodiment 3)
Fig. 7 is the longitudinal sectional view of the 3rd embodiment of clip A of the present invention.In this embodiment, as shown in Figure 7, respectively be provided with a ribs 9, also respectively be provided with a ribs 11 in the relative both sides of the edge of each clamping plate 3,3 at the opposite end of the gland body portion 5 of gland 4.
When the size of clip A was big, chuck 1 was preferably made by thin material, so that utilize the elastic resistance of clamping part 3a, 3a.Yet if the material attenuation, the rigidity of chuck 1 will reduce, so by adopting ribs 11 to strengthen chuck 1 on clamping plate 3,3.Ribs 11 also plays the effect that does not injure user's finger in use.
In addition, an excessive external force might act on the gland 4 of a large-sized clip A, thereby can cause the plastic deformation of gland 4.At this moment, ribs 9 just plays the effect that pressing plate 6,6 is too opened and reinforce gland 4 that suppresses.Ribs 9 also plays the effect that applies a strong pressure and need not to increase the thickness of gland 4, thereby reduces the manufacturing cost of gland 4.
What should give attention is that the present invention is not limited to top embodiment.If necessary, can change the body portion of pressing plate 6,6 of the clamping plate 3,3 of chuck 1 and gland 4 or length, transverse width, width or height X, the X ' of similar portions.The both available identical materials of chuck 1 and gland 4 is made, and also available different material is made.
The invention provides a kind of clip of novelty, this clip has a clamping force by the gap turn narrow that a pressure is diverged between two clamping plate of formula chuck.Compare with the clip such as the prior art of jewel folder, duplex clip, metal plate holder etc. that needs servicing unit or similar device, clip of the present invention does not need servicing unit, and just can produce a strong clamping force by a shirtsleeve operation.
Because clamping plate are done the extension of fork formula from the body portion to the end, paper can successfully inject clip.When gland is shifted final propelling position onto on chuck, when sliding on clamping plate, gland press clamping plate and make clamping plate approaching mutually inwardly, because the insertion gap between the pressing plate of gland is narrower than the maximal clearance between the clamping plate of chuck, thereby can clamp paper firmly between clamping plate.
Clip of the present invention can clamp paper or similar articles safely securely, and need not to use other servicing unit.
