Description

Clip

The present invention relates to be used for clip that clampings such as documentation are tied up.

As everyone knows, traditional file is such as with the finger control actuating strut, make its contact-making surface expand the clip of opening and using, the dual little paper clip that is wound into ring-type will be after the bending of elasticity plate body forms contact chip up and down, and other uses the clip etc. of certain pressing device (clamp device).

For above-mentioned two-sided clip, though can produce chucking power, yet,, need contact chip to be expanded and open with very big power operation when clip becomes when large-scale, also have the influence that to expand out or be subjected to action bars, the higher unfavorable condition of volume when making the file that utilizes this kind clip to tie up overlapping, for little paper clip since be with file the ring between, thereby clamping force is little, has the situation that how can not clamp thick file.

In addition, for the clip that must use above-mentioned press device, though easy and simple to handle, spend the labour less, also have sufficient clamping force, need to be equipped with in addition the clip pressing device.

Therefore, the clip of the applicant's design opens the contact-making surface up and down that is closure state with external force relatively at every turn slightly, then with its power of returning from clamping traditional clip difference of file up and down, need not to use other device, make with pushing force that to expand the contact-making surface up and down open closed and obtain clamping force.

Therefore, these problems that the present invention exists in view of above-mentioned traditional clip just, its purpose are to provide a kind of device of pushing file that need not to use in addition, and are easy and simple to handle, can produce the clip of abundant clamping force.

The present invention is made up of clip body and thrust cap in order to achieve the above object, from the two ends of the turn of bilge of clip body continuously and expand to open and extend to form up and down holding piece and form described clip body with required width, described thrust cap has the holding piece up and down that continuous extension is provided with from the two ends of the thrust cap bending part that forms required width, this is engaged with the position up and down of the close bending part of above-mentioned clip body on top of holding piece up and down, make the width that forms between above-mentioned top than the Breadth Maximum that forms between holding piece up and down of clip body also narrow make above-mentioned thrust cap can outside in clip body on before and after slide, make that the holding piece up and down of clip body is close mutually in pressed state.

In addition, also can make the top of the clamp clip up and down bending to the inside of clip body.

Clip body and thrust cap can be made with elastomeric material.

Also gathering sill is set,, is provided with and prerotation vane that gathering sill matches simultaneously on the top of the clamp clip up and down of thrust cap at the position up and down of clip body.

Above-mentioned structure is owing to form clip body to make and expand the holding piece up and down that open form becomes from its bending part and become top expansion shape, thereby documentation to be tied up etc. successfully can be inserted clip inside.

When subsequently with thrust cap when the slide outside of clip body pushes, because it is also littler than the Breadth Maximum that forms between holding piece up and down of clip body at the insertion width that forms between holding piece up and down of this gland, thereby the holding piece up and down of this gland is slided before and after pushing to the holding piece up and down of clip body from outside to inside, make that the clamp clip up and down of clip body is near each other.

Below, with reference to the accompanying drawings one embodiment of the invention is described.

A among the figure represents clip of the present invention, and this clip A is made of clip body 1 and thrust cap 4, forms by the platysome bending that metallic plate or synthetic resin board etc. are required.Can use elastomeric material or non-elastic material.

Clip body 1 is that formation has the bending part 2 of required width X, makes from its two ends extension simultaneously and expands open form one- tenth holding piece 3,3 up and down from its center foldover is curved with above-mentioned required flat board, in addition, in the present embodiment, also the front end bending to the inside of this holding piece 3,3 is made to have required width and form clamping part 3a, 3a, by formed space between this clamping part 3a, the 3a as inserting space Z (figure (a)).

Therefore, with regard to present embodiment,, become formed Breadth Maximum between the holding piece up and down 3,3 of clip body 1 by formed width V between the crooked position 3b, the 3b that form clamping part 3a, 3a.In addition, the foregoing description is the clamping part 3a that forms by bending.As long as yet that the top that will form flat clamping part 3 curves clamping part 3a is just passable,, become Breadth Maximum by this clamping part 3a, the formed insertion width of 3a Z in this occasion.And the width X of above-mentioned bending part 2 can be suitably corresponding to the documentation thickness of tying up, and do not add any qualification.

On the other hand, thrust cap 4 is for having from the curved back of its central folding required flat board the bending part 5 of required width X ' from formation, make again and extend to form holding piece 6,6 up and down from the two ends of bending 5, form insertion width Y 6,6 of this holding pieces, yet, make the bending part width X narrow (Fig. 2 (b)) of this width Y than above-mentioned clip body 1.And also the bending part width X than thrust cap 4 is narrow to make insertion width Y.In addition, the invention is not restricted to an above-mentioned example, insert the Breadth Maximum V of width Y less than above-mentioned clip body 1 as long as make, just can, for example, insert width Y less than insertion width Z as long as make, remainder can be any.

Above-mentioned each required width can be expressed with following formula.

(inserting width Y＜bending part width X＜insertion width Z＜width V)

But following formula is only as a side, if satisfy at least insert width Y＜width V relation just can, make the relation etc. of insertion width Y＜insertion width Z can be any.

And, can do following whole the setting, make after holding piece up and down 6,6 expansion with above-mentioned thrust cap 4 that the outer interlocking of its front end is combined in clip body 1 with the close position up and down of bending part Z on, the front end of the holding piece up and down 6,6 of above-mentioned gland 4, can on the holding piece up and down 3,3 of clip body 1, before and after the direction of front end 3a, 3a, slide.

In addition, when finishing the pushing of thrust cap 4, the top clamping part 3a of the holding piece up and down 3,3 of clip body 1, that 3a is pressed state mutually is approaching mutually.Much less, also passable even clamping part 3a, 3a contact with each other.

As shown in the figure, on the holding piece up and down 3,3 of clip body 1, gathering sill 7,7 is set, the interior curved guide sheet 8,8 that cooperates with above-mentioned gathering sill 7,7 in the front end setting of the clamp clip up and down 6,6 of thrust cap 4 simultaneously, in view of the above, because the prerotation vane 8,8 of thrust cap 4 with the sliding-contact shape and can not embed in the guiding groove section 7,7 of clip body 1, is positioned at (referring to Fig. 1) on the clip body 1 thereby thrust cap 4 is slided in gathering sill 7 by the prerotation vane 8 that makes its introversion with being pulled out.

In addition, because in this example, the prerotation vane 8,8 of thrust cap 4 embeds the guiding groove section 7,7 of clip body 1 with the sliding-contact form and can not come off, simultaneously formed insertion width Y is littler than the bending part width X of above-mentioned clip body 1 between the clamp clip up and down 6,6 of thrust cap 4, thereby does not worry that clip body 1 can separate suddenly with thrust cap 4.

Other embodiment shown in Fig. 4-7 for another example also can be provided with one and even a plurality of dowel 9 respectively on the front end inner surface of the clamp clip up and down 6,6 of thrust cap 4 ... (projection with required form) replaces above-mentioned prerotation vane 8.In addition,, be not limited to non-perforation shape, also comprise the hole that diagram connects shape like that for described slot part of the present invention.

Below, describe with regard to application examples.

At first, owing to clip body 1 is formed the expansion shape from the top that its bending part 2 forms the holding piece up and down 3,3 that expands the open form shape, thereby successfully documentation B is inserted clip inside (referring to Fig. 1 (a) (b)) from the insertion width Z that forms between top clamping part 3a, the 3a of clamping 3,3 up and down.

Subsequently, when thrust cap 4 being placed on the holding piece up and down 3,3 of the clip body 1 on the above-mentioned documentation B, (the arrow W direction shown in each figure) slided and pushed forward, form on the holding piece up and down 3,3 of 6,6 pairs of clip body 1 of holding piece up and down of above-mentioned gland 4 the outside-in pushing of sliding, make the holding piece up and down of clip body 13,3 near each other (inserting width Z dwindles), thereby can be from up and down with documentation B firm grip (referring to Fig. 1 (c) and Fig. 3).

In addition, because clip shown in the drawings adopts elastomeric material to make, clamp clip 3,3 is subjected to the pushing force effect of holding piece up and down 6,6 of thrust cap 4 and the B of clamping documentation securely after the strain up and down.In addition, clip A of the present invention is being untied occasion, then opposite with above-mentioned action, just can remove the pressed state of the holding piece up and down 3,3 that puts on clip body 1 as long as move thrust cap 4 backward.

Fig. 8 and Fig. 9 represent other embodiment again, have the thrust cap 4 of the holding piece 6,6 of the such length of the crooked position 3b that makes its top prerotation vane 8,8 can cross clip body 1 exactly in formation.Because when push operation by thrust cap 4, when making top prerotation vane 8 cross crooked position 3b, just cross crooked position 3b as the dead point after, make 3,3 pressurizeds of holding piece up and down of clip body 1, have when can improve clamping force, and the advantage that thrust cap is come off.

In addition, the various embodiments described above be not limited to for an example, it is not done unnecessary qualification, for example to each holding piece 3,3 up and down of the expansion angle of clip body 1, clip body 1, thrust cap 4,6,6 length, transverse width, bending part width X, X ' etc. all can be conceived suitably change of do under the prerequisite in the present invention.

Clip body 1 and thrust cap 4 can adopt same material also can adopt different materials to make.

The present invention is exactly the closed then a kind of new clamp that obtains clamping force of contact-making surface up and down that makes the clip body that initial expansion opens with pressing force owing to having above-mentioned formation, for traditional two-sided clip, with external force the expansion of contact-making surface up and down of closure state is opened slightly with each, utilize its power of returning from the clip that clamps file up and down (two-sided clip, use the clip of binding clasp) etc., provide to need not to use binding clasp, easy and simple to handle and can produce the clip of the novel practical of abundant clamping force.

Exactly owing to take to make clip body to be to expand to open holding piece up and down that shape forms and become the top to expand to open shape, documentation to be tied up successfully can be inserted clip inside from its bending part; And, if thrust cap is pushed along the slide outside that is arranged on the clip body on the above-mentioned documentation etc., at least the Breadth Maximum between the holding piece up and down than clip body is little owing to the insertion width between the holding piece up and down with this gland forms, thereby the outside-in of holding piece up and down that makes this gland slides while pushing to the clamp clip up and down of clip body, make that the clamp clip up and down of clip body is near each other, thus can be from the documentation of pushing down up and down and clamping.
