Description

Stapler

Technical field

The present invention relates to a kind of stapler, comprise one constitute base mostly lower component and can be fixed on the upper-part on the rearward end of lower component usually pivotally.

Background technology

The storehouse that is used for staple is usually located at upper-part.Be pressed downwardly onto the binding thing that staple is pressed into respectively be arranged on the lower component, a folded paper for example through free end, so that they are bound with the front of upper-part.Possibly be difficult to apply essential bookbinding power when thicker or paper is hard at paper buttress through directly pushing upper-part.

So stapler is developed, wherein, is not through directly pushing upper-part but applies bookbinding power through a lever indirectly.US-PS 7,140, and 526, the announcement of Japanese Utility Model 2084404, US-OS 2002/0005427 A1 and International Application No. WO 03/082528 A1 for example shows this equipment.In addition, for example disclose the pincers of stapling together by open DE 694 12 890 T2 of the German of German utility model 91 06 427 U1 or european patent document, they have a lever equally, are easy to apply essential bookbinding power through said lever.

In view of the above, the stapler of prior art has following problem: it needs the macrostructure space and/or injects the degree of depth like the only very little paper of permission in the stapling pincers owing to lever.

Summary of the invention

Therefore, the objective of the invention is to, realize a kind of stapler, this stapler structure is little, can operate and have big paper as far as possible with few power consumption and inject the degree of depth.According to the present invention; Said purpose is realized by such stapler; This stapler comprises the upper-part that a lower component and can be connected with this lower component pivotally; The free end of this upper-part for staple is hammered into effortlessly be arranged in the binding thing on the lower component and can be pressed downwardly onto on the lower component by a lever, promptly in the lever pattern; It is characterized in that, the said function of stapling together in second mode of operation that does not have lever force to strengthen, be to be used for bookbinding in the basic model, and said lever is arranged on the stapler for this reason with clinging on the upper-part.

Lever so is set, the basic working modes that makes lever strengthen for no lever force be deexcitation and can cling on the upper-part, thereby can stapler be placed the physical dimension of the conventional stapler of no lever transmission.The amount of and binding thing few at paper buttress hour, stapler can also use under the situation of not using lever as the conventional stapler that does not have force transformation mechanism in following this position that is called basic model or home position.On the contrary, strengthen ground and realize in the lever pattern of bookbinding having power through presses lever, though lever from the upper-part projection of stapler, therefore also can be realized with the little heavy binding thing of operating physical force bookbinding, because overcome big stroke through lever.If do not use stapler, then can be placed in the home position with the lever that reclines, and compare with the stapler that does not have power to strengthen and not need more space.

Fig. 8 is illustrated in the object in the basic model, when forwarding finishes among Fig. 7.

The specific embodiment

Fig. 1 illustrates stapler; The lever 3 that the lower component 1, that comprises that it is preferred but constitute base optionally is connected on its free end with upper-part 2 at the upper-part 2 and that can be fixed on the rearward end on this lower component in illustrated embodiment with moving pivotally; This lever in the lever pattern from upper-part 2 to upper process, thereby shape at an angle between upper-part 2 and lever 3.Fig. 2 illustrates the stapler when forwarding finishes in the lever pattern equally, wherein, through lever 3 upper-part 2 is pressed downwardly onto on the lower component 1.At this, the angle between upper-part 2 and the lever 3 also diminishes.

Fig. 3 and 4 is illustrated in the stapler in the basic model, that is to say, and wherein lever 3 un-activations, therefore this lever abuts on the upper-part 2.Fig. 3 representes the moment before forwarding begins.This also is to save the position that ground, space is placed or deposited stapler.Subsequently, through the end E that is connected with upper-part 2 of presses lever 3, being set out by the position among Fig. 3 is pressed downwardly onto upper-part 2 on the lower component 1 to the position shown in Fig. 4, can under the situation of not using lever 3, bind more a spot of paper thus.In institute's drawings attached, on the upside of lever 3, can see an operated key 4, this operated key is used between according to the lever pattern of Fig. 1 and 2 and the basic model according to Fig. 3 and 4, changing.

At length explain the accurate function of stapler according to Fig. 5 to 8, wherein, for for simplicity, not shown or part illustrates the cladding element that in Fig. 1 to 4, can see and the housing parts of stapler with cutting open.Fig. 5 and Fig. 6 are corresponding to the position of Fig. 1 and Fig. 2, and Fig. 7 and Fig. 8 are corresponding to the position of Fig. 3 and Fig. 4.

In the stapler of this embodiment, lever 3 can be connected with upper-part 2 around pivotal axis 21 pivotally.Upper-part 2 installs around again to be ordered axle and 6 can be hinged on pivotally on the lower component 1.At this, bookbinding axle 6 is positioned on the rearward end of stapler, injects zone 7 so that vacate for unshowned binding thing in front.Relative therewith, the free end E that pivotal axis 21 is arranged on upper-part 2 go up and therefore as far as possible far with bookbinding axle 6 partition distance.Therefore, in the lever pattern shown in Fig. 5 and 6, lever 3, upper-part 2 and lower component 1 form a kind of jagged layout.Operation to lever 3 realizes through pushing its outer end A, in order to trigger forwarding upper-part 2 is pressed downwardly onto on the lower component 1 on opposed free end E thus.For this reason, lever 3 has a press element 8, and this press element affacts on the upper-part 2 in the lever pattern of Fig. 5 and 6.

In order under the situation of the big reeve degree of depth that is used for binding thing, to realize long as far as possible lever 3 simultaneously, stapler has a conversion transmission mechanism.This conversion transmission mechanism preferably has one and is in driving element 11 that effect is connected and with lever 3 (at this through press element 8) and is in lower component 1 and acts on the drive element 13 that is connected.This effect connects can be through being engaged on mechanically simply but realize that reliably this engagement can directly perhaps as shown in the figurely realize indirectly.For so-called gearshift, promptly the opposed lever of free end E with upper-part 2 grips end A, between driving element 11 and drive element 13, needs at least one actuated element 12.Therefore, shown embodiment has the conversion transmission mechanism of triple axle, comprises that pivotal axis 22 and that the pivotal axis 21, that is used for driving element 11 is used for actuated element 12 is used for the pivotal axis 23 of drive element 13.

In order during forwarding, to realize different gearratios, stapler preferably has a curve orientation portion, this curve orientation portion part of transmission mechanism advantageously as in the embodiment shown.In this embodiment, curve orientation portion realizes through the curved profile 33 of drive element 13, moves along the guiding roller bearing 15 that is installed on the lower component 1 in the motion process of this curved profile during forwarding.Through having the curved profile 33 of the more smooth curve part that the side and that at first tilts is close to it; When continuous downwards presses lever 3, at first realize the strong decline of the free end E of upper-part 2; As long as still need not be used to hammer into the power of staple, and the big power effect on the upper-part 2 appears affacting in the further progress that moves downward of lever 3 when only also wanting little moving downward.Therefore, hold constantly as far as possible and therefore less on the whole trying hard to keep of especially when the paper amount is big, will applying during the whole forwarding.

For stapler is transformed in the basic model shown in Fig. 7 and 8 from the lever pattern shown in Fig. 5 and Fig. 6, must operate operated key 4 in the embodiment shown.

For this reason,, and at least one retaining element is moved, promptly move forward along direction 41 equally with press element 8 at this blocking element 17 along the direction of arrow 41 operated key 4 that moves forward.If lever 3 is descended, then this lever is parallel to upper-part 2 ground and clings on the upper-part 2.The preferred hook-shaped blocking element 17 that constitutes as shown in the figure automatically snaps among the breach D of upper-part 2 and with lever at this and in the home position shown in Fig. 7 and 8, is fixed on the upper-part 2.The same press element 8 that moves forward along direction 41 simultaneously is not pressed onto on the driving element 11 in that kind shown in Fig. 5 and 6 now for another example, does not have in the position of effect but be placed in respect to upper-part 2.In the embodiment shown, this realizes through following mode: press element 8 enters into the space 31 of driving element 11.Stapler now can not have that lever force strengthens according to the basic model of Fig. 7 and 8 in be used for bookbinding by this way equally, that is, and with upper-part 2 as in the conventional stapler in its free end E upper edge being directed downwards of arrow P push.

If in stapler, be converted to the lever pattern that has Fig. 5 that lever force strengthens and 6 from the basic model of Fig. 7 and 8, then must be again in illustrated embodiment along direction 41 operated key 4 that moves forward, so that blocking element 17 is broken off relations from breach D.Must lift simultaneously the outer end A of lever in the direction of arrow F, be converted to its effect again by the press element 8 of spring pretension for this purpose thus and be connected in the active position on the driving element 11 according to Fig. 5 and 6.At this, the axle 5 in the upper-part 2 is as the top backstop of lever 3.In the embodiment shown, operated key 4 and blocking element 17 be equally against direction 41 spring pretensions, thereby operated key 4 and blocking element 17 are got back in its position at the back along direction 41 moves after, moving automatically again during at releasing operation key 4.

Therefore, as just embodiment illustrate but do not limit the invention general idea this stapler be constructed such that structurally lever pattern and basic model are ad eundems.Therefore, each user can regulate by its main preferred mode of operation.

In alternative, a unshowned embodiment, stapler has a preferred mode of operation (this preferred mode of operation can be basic model or lever pattern), and stapler revert to after forwarding in this preferred mode of operation automatically.For this reason, must remain in the mode of operation of interim selection through ratchet or one (press element 8 or the blocking element 17) of other similar measures in the conclusive retaining element of the duration of forwarding chien shih.Subsequently, forwarding itself is unclamped for example ratchet, thereby stapler automatically revert in the preferred mode of operation after this forwarding again.If in other, not preferred mode of operation, bind, then this must for example import through the operating operation key before each single forwarding.

Stapler according to the present invention has been realized all requirements through its refining structure and has mechanically been remained stable and structure compactly particularly.It can be saved ground, space and fold (basic model), as the conventional stapler that does not have power to strengthen, uses (basic model) or be used to bind more a large amount of paper or stone binding thing (lever pattern) with a wet finger by the power enhancing through lever arm.When using the conversion transmission mechanism, when being used for the big reeve degree of depth of binding thing, can realize long lever arm and thereby be used for the less power consumption of forwarding.
