Description

The paper punch that has centring means

Technical field

The present invention relates generally to stationery and office type articles for use technical field.The invention particularly relates to the paper punch that designs for the punching that is used for importing to the paper in the file that has ring.The present invention more relates to a kind of paper punch that has centring means, and it can allow to make one page to be punched or multipage paper with respect to the accurate location of card punch itself, so that the time make the hole be positioned at accurate position and/or have accurate spacing in punching.

Background technology

In order to realize having the good visual effect of file of ring, all paper that are added into must correctly punch, so that place matchingly with other paper of before putting in the ring.

In European patent application EP 1 332 845 A2, show a kind of paper punch of routine at the preamble of its claim 1.This card punch is furnished with control makes the good Optical devices that insert of paper to be punched.Yet these Optical devices can not realize being used for guaranteeing the centering of the pinpoint paper in hole.

Yet people also once proposed the multiple solution that needs the centering of punching paper perhaps to locate with respect to card punch realization itself.

A kind of known card punch that has centring means is arranged, and it is provided with the central visual mark of flechette-type for example or fork-shaped sign on the leading edge of card punch bottom.In this case, the user must own make marks at the center of paper to be punched, and especially with this paper doubling, the center of paper and card punch visable indicia is coincided.This use binding character is strong excessively, and can stay folding line beating on the paper of via hole.

Many drifts paper punch that major part is thrown in the market has movable measuring staff, different scales is arranged to mate the different antiquarians that exists at present respectively, for example standardized " A4 ", " A5 " or " A6 " size on this measuring staff.This structure need to allow the drift pre-determined bit of punching paper with respect to card punch.Yet the measuring staff of these card punch is difficult for using, and the user often can not use them rightly, and consequently, the paper of new punching can be with respect to the paper dislocation of having inserted in file.In addition, these measuring staffs might be lost or damage, and therefore the user is forced to old way to come mark is carried out at the center of paper.

Also there are at present some very flat and the integrated file type card punch of file.These card punch are fixed in the ring of file, and are furnished with the scale of being processed by plastic material by the punching of the spacing dimension of ring, and this scale and outfit are used for linking to each other for the thin hinge of the drift of paper punching.These file type card punch have less boring ability because of its use pattern, and the quantity of the paper that this point can punch through its once-through operation embodies.

French patent application FR 2 545 409 A1 show a kind of special file type card punch, and it not only comprises rule, also comprises fixedly limited block at its end, and the edge mate of the limited block and the paper that need punch is to guarantee the centering of paper.This card punch can't adapt to the paper of different size at least well in its original embodiment except that the punching ability.

At last, also have the small-sized card punch that is used for getting unique hole, this card punch is mainly student's design, and is positioned on the ring of file.Here its trade name that can propose with the applicant is an example for the card punch of " PUNCHITO ".A kind of like this single hole card punch has the fork portion that is embedded in the file ring and rotates to avoid it to center on ring.The location of being realized by such card punch is assumed that can guarantee in paper that will be to be punched and the correct location that is placed on each hole that paper in the file beaten on the paper when aliging.Yet the user is necessary for each punching and the operation of override interrupt device, so just need the user control paper to be punched hand and the operation card punch hand between good coordination is arranged.

Summary of the invention

The present invention is intended to remedy the deficiency of aforementioned known solution; Its purpose is to propose a kind of like this paper punch that has centring means; Its embodiment is very easy and economical, and can guarantee by accurate position or spacing punching, and is convenient to operation; Simultaneously no matter as far as the still quantity of punching simultaneously of number of paper, it can both provide powerful punching ability.

For this reason, the main purpose of the present invention is to propose a kind of paper punch, and this card punch comprises: base; At least two are mounted to the drift that can move and have preset space length with respect to base; And be used for manual control device that drift is moved relative to base simultaneously; This card punch is characterised in that; Its base vertically is provided with on the limit thereafter and is used to make the device of this base with respect to the ring location of file; Spacing between the ring of this document folder is corresponding with the spacing between the drift of card punch, so that the base of card punch can be resisted against on the ring of file according to the precalculated position through its outside.

In a preferred embodiment of paper punch according to the invention; This positioner is made up of the locating slot in back vertical limit of two bases that are arranged on card punch at least; In the plane in locating slot is located substantially on and is included in perpendicular to said back and with the drift of card punch, each locating slot all can be connected on the ring of file.

In a special simple embodiment, card punch of the present invention is a kind of card punch that has two drifts that separate according to preset space length, and said positioner is made up of two locating slots, and the spacing between the locating slot is identical with spacing between the drift.

By way of example, two separated spacings of locating slot of card punch base are 80 millimeters, and the spacing of the ring of the file that this spacing and Europe are the most frequently used is complementary.

The use principle of card punch of the present invention is following:

The user is through the location between the ring that realizes card punch and file that coincides of a plurality of rings (perhaps a pair of ring) with the locating slot and the file of card punch base.Card punch aligns with ring, and the drift of card punch is therefore corresponding with ring.Paper to be punched be directed to subsequently card punch in the slit of locating slot, and align with the paper of putting in the file.Therefore, perforated can be felt relieved with respect to card punch.The user can common mode handle drift so that paper is punched.At last, card punch is taken off, the user can put the paper of just beating via hole in the file at once.

More than individual paper of describing for the purpose of explaining can substitute by many folded paper very simply, realization is felt relieved simultaneously thus.

The paper punch that has centring means of the present invention comprises lot of advantages.

Particularly, the realization of this card punch is very simple, economical, because centring means in fact only needs to be realized by two locating slots in the back of card punch base.Traditional have straight line or a little on the basis of the card punch of circular base, realize that through molded, moulding or processing the industrial cost of modification of two locating slots is almost nil.Here the optional feature that has no is especially such as the frangible moving-member of slip measuring staff.

Because the risk that does not have wearing and tearing and loss of parts or damage, the extreme simplification of centering parts also can guarantee to obtain better reliability.

Remove aforesaid structural advantage, the centring means that the present invention proposes provides very easily and has used:

The location of card punch is to lean against on the ring of file through the outside with card punch to realize.Therefore, all are embedded into card punch among the ring and from ring, its operation of taking off are not needed, and having simplified centering operation and punch operation like this, and having made it more quick.

In any case, the location all can very reliable and accurately be realized.In fact, this location can be described as through " mechanical positioning piece " and realizes, the file ring is embedded in the locating slot of card punch, can eliminate all manual adjustments like this or with respect to the accidentalia and the inexactness of the vision localization of locator or scale.In addition; At least two file rings are embedded in the locating slot of card punch respective amount; And the spacing ability that the bottom of these locating slots has can be guaranteed the orientation that card punch is good, and need not card punch all is embedded on the ring to avoid it to center on ring rotation (this is opposite with above-mentioned existing " single hole " card punch).

At last, the principle that has the paper punch of centring means of the present invention is given this card punch more applications:

Though be the ring location with respect to file, in actual use, card punch of the present invention keeps being independent of file.Therefore it does not have the constraint and the restriction of file type card punch, can have bigger punching ability, and all unrestricted on the quantity of the quantity in hole and paper.

In addition, the positioner that proposes here can be complementary with all types of paper punch, no matter is which kind of punch systems, no matter is which kind of control system of these drifts also, and card punch comprises base all the time, and the locating slot that for example the present invention proposes can be set on base.

The specific embodiment

Fig. 1 to Fig. 4 shows a kind of paper punch, and its integral body is indicated by label 1, and in one embodiment design to be used for getting simultaneously two spacing E for example be 80 millimeters hole.

According to known mode, card punch 1 comprises base 2 and hypocraterimorphous handlebar 3, and handlebar 3 is pivotably mounted on side stand 5 and 6 around lateral shaft 4, and side stand 5 and 6 are fixed on the upper side of base 2.Handle 3 cooperates with two drifts 7 and 8, and drift 7 and 8 is mounted to and can slides in parallel to each other, and upwards resilience under the effect of corresponding spring 9 and 10, the punching spacing that the spacing E between the drift 7 and 8 obtains corresponding to hope.

On " front portion " of the rotating shaft that is substantially perpendicular to handle 34 face, the edge that two side stands 5 and 6 respectively have a slit 11, one or more paper to be punched can insert wherein.

And in contrast a side, promptly on " rear portion " face, vertical limit 12 of base 2 has the locating slot 13 and 14 of two symmetries.First locating slot 13 is arranged in such plane, it be substantially perpendicular to limit 12 and and drift 7 is included in.14 of second locating slots are arranged in such plane, it and aforementioned plane parallel and another drift 8 is included in.Therefore, as shown in Figures 2 and 3, the distance apart between the drift 7 and 8 of E and card punch 1 of separating between two locating slots 13 and 14 equates that this for example can be 80 millimeters apart from E.

Fig. 5 to Fig. 7 shows the situation that paper punch of the present invention is used in combination with the file that contains ring (anneaux).In this embodiment; Whole label is that 15 file comprises two rings 16 and 17; Spacing E between two drifts 7 of their spacing and card punch 1 and 8 is corresponding, and and then with two locating slots 13 and 14 of the pedestal 2 of card punch 1 between the distance of separating corresponding.

Therefore, the user holds card punch 1, and through on two rings 16 and 17 that two locating slots 13 and 14 are connected correspondence respectively, thereby its outside is resisted against two rings 16 and 17 of the file 15 that is in opening.Paper 18 that then will be to be punched (being assumed to be individual here) imports in the slit 11 of card punch 1, and goes up the paper 19 of lower limb in making it and putting into ring 16 and 17 before through aliging and align.Therefore paper 18 to be punched feel relieved with respect to ring 16 and 17, and with respect to card punch 1 centering, because card punch 1 has been realized the centering on ring 16 and 17.

The user handles card punch 1 in due form,, forces down handle 3 and two drifts 7 and 8 towards the opposite direction of spring 9 and 10 screen resilience effects that is.Therefore paper 18 got two holes, and the spacing between these two holes is E, feels relieved with respect to the whole length of this paper 18 in two holes.

At last, card punch 1 is taken off, and can (or after a while) at once perforated 18 put on the paper 19 in ring 16 and 17, and then realization puts it in the file 15.

In the scope that does not exceed claim of the present invention; Can also expect can on the card punch base, design surpass two locating slots, or can be with locating slot separately with the spacing of different numerical value, or can these locating slots be replaced with the positioner (for example, can adopt the simple convex shoulder that cooperates in a similar manner with the ring of file) that is equal to.Under identical thinking; The pure mechanical features of card punch and the outer shape of card punch and size can have a lot of versions; But these card punch all remain with the centring means of location grooved, so just can allow to be resisted against the location of realizing card punch on the ring of file through the outside with them.
