Description

Ring binding tool

A kind of ring binding tool involved in the present invention is to have the bookbinding bar is opened and closed, and the loose leaf paper in band bookbinding hole is adorned, got, and is used to bind the ring binding tool of purpose.

This ring binding tool originally comprises: having curves inwardly at dual-side forms the cover body of support rib, be configured in that the inside and outside edge of this cover body remains on the support rib, inner edge connects the top can protruding folding and a pair of start plate of recessed folding, the bottom is supported on that through hole that start plate, top pass cover body stretches out, is accompanied by the protruding folding of start plate and the action of recessed folding forms a pair of bookbinding bar that opens and closes, the rotating operation bar that is propping up along cover body length direction two ends pivot.

On this member, outwards push the rotating operation bar, the bottom of this rotating operation bar just pushes the junction surface of the start plate of recessed folding state, and makes it be transformed into protruding folding state, will bind bar and open.On this member, a certain amount of by the recessed folding of start plate, bookbinding bar closure state by the rotating operation bar is inwardly rotated, the end of just limiting the start plate by the bottom of action bars, the start plate just can not be inverted to protruding folding state, and makes it locking.This situation also is many.

, for the start plate, be elongated with respect to the length of front cover spine (back of the body table paper), therefore just limited the end, limited opening of bookbinding bar; But, be arranged near the bookbinding bar the start plate central authorities because impact or other external force effects when falling are often opened owing to reasons such as reversing of start plate.Therefore, do not binding under the situation of bar near the end, although locking the start plate, also often cause the unfavorable condition that paper that bookbinding gets up comes off.

For improving this unfavorable condition,, disposed a pair of slide mass along its length slidably near extending to central authorities by the cover body end in the bottom of start plate.And be provided with action bars in the slide mass outer end, by the slip of the projection that is fixed in slide mass, the start plate is become by recessed folding state is protruding folding state, or with the locking of start plate in recessed folding state.

But this structure owing to the outside slippage of action bars that must two ends be set, open the bookbinding bar, is therefore felt not smoothly (indisposed sense) concerning the action need person of the rotating operation bar having got used to extensively popularizing.And, be difficult to accomplish easy to use owing to want two hand operateds.Be member and rotating operation mode different of slidingtype more in addition, an end of bookbinding paper feed is inserted the finger space with action bars with not forming, and is difficult to add that enough strength carries out slide.Also to engage at the both sides action bars, the shortcoming of the unsuitable lengthening of total length of ring binding tool occur with necessity point.Promptly, the paper that bookbinding is entered, it is certain to press specification, form respectively between the ora terminalis of paper and two action bars to insert and refer to the space, the total length of ring binding tool has to extend than the original rotary type control member that uses of popularizing, the length of file is also elongated, thus cause easily and original article between inconsistent on the size.

The present invention is a purpose to eliminate above-mentioned unfavorable condition promptly.For reaching this purpose, taked following concrete mechanism.That is ring binding tool, involved in the present invention possesses such architectural feature.It includes: have the cover body that is bent to form support rib in both sides of the edge to the inside, be configured in this cover body, outer rim remains on the support rib, inner edge can protruding folding and recessed folding be in a pair of start plate to the top, the bottom is supported on this start plate, the top is protruding by the through hole of cover body, be accompanied by the action of the protruding folding of aforementioned start plate and recessed folding and form and open, the a pair of bookbinding bar that closes, add on the start plate and can be along the slide mass of cover body length direction advance and retreat, pivot Zhi Yu is along the rotating operation bar of cover body length direction one end, the rotational action of this rotating operation bar is transformed into the action mapping device of the advance and retreat action of aforementioned slide mass, needed local setting of aforementioned slide mass, be accompanied by slide mass advance or backward movement makes the start plate become opening of protruding folding state by recessed folding state to suppress mechanism, desired local setting of aforementioned slide mass, be accompanied by slide mass retreat or forward motion is matched with the start plate, and this start plate is locked in the blocking mechanism of recessed folding state.

For the start plate being suppressed the kilter that reaches locking by the advance and retreat action of slide mass, peristome is set up at junction surface at two start plates separately, on slide mass, establish the projection of inserting this peristome, aforesaidly open that to suppress mechanism be the inclined cam surface that is provided with in projected front ends or rear end, and aforesaid blocking mechanism can be the recess that is arranged at the rear end of projection or front end, partly links to each other with the edge of opening of start plate.At this moment, prevent to bind coming off of seat, preferably projection is arranged near near the bookbinding bar of the central part configuration of length direction for more certain.In addition, in such structure, in order to prevent to open the action of suppressing mechanism and blocking mechanism and become unreliable owing to the distortion of slide mass and off normal make, on slide mass, be provided with a plurality of projections, simultaneously between each projection of this slide mass, have slotted hole along the advance and retreat direction, can keep guiding slide mass by the steady pin that can connect this slotted hole slidably.

The structure that can simply not expand is guaranteed reliable action, this member has comprised: the operation bar pivot is propped up following lappet in the cover body end, the Extendible flake that descends the lower end of lappet to extend outward thus, from the parallel upright sheet that erects in the outer end of this Extendible flake with following lappet, the operating portion that this upright sheet upper end is wholely set.And the action mapping device is made: open the hole at aforementioned Extendible flake and upright sheet intersection, establish crooked upright sheet in the outer end of slide mass, the upright sheet of this bending is matched with aforementioned through-hole.At this moment, for the THICKNESS CONTROL with cover body gets as much as possible for a short time, be preferably in down to leave on the lappet and prevent the recess that disturbs with crooked upright sheet.

For such structure, the rotating operation bar is rotated, by the effect of action mapping device, slide mass advances or retreats, suppress by opening that mechanism advances this or backward movement is transformed into the power that makes the start board reversal, this start plate becomes protruding folding state by recessed folding state, then binds bar and opens.As this bookbinding bar is suppressed toward mutual close direction, the start plate is returned to original recessed folding state, can keep its closure state thus.And state further inwardly rotates the such rotation action bars thus, and slide mass retreats or advances, and can prevent that by the blocking mechanism that is provided with on this slide mass the start plate from reversing to protruding folding state, and the bookbinding bar is by locking.This blocking mechanism owing to be to have utilized the advance and retreat of slide mass to move to limit the start plate, is not limited to the end of start plate, so can be disposed at the optional position of slide mass.For this reason and since with its be disposed at because of impact and bookbinding bar that the external force effect is easily opened near, so can prevent coming off of loose leaf paper effectively.

Moreover, the such rotation action bars, an end that only is arranged at cover body is just enough.Can carry out rotating operation freely to this rotating operation bar one hand, open the bookbinding bar or carry out locking with this.And this structure refers to make it rotate operating physical force that can be bigger to the slide mass transmission in the upper end of such rotation action bars owing to execute.Therefore, the same with the member of original rotating operation formula, needn't guarantee between rotating operation bar and bookbinding seat edge, to stay the dark space that refers to of inserting, thereby, can design at an easy rate with the much the same total length of having popularized originally of rotating operation formula member ring binding tool.

As according to above-mentioned the present invention, also can obtain reliable locking on the bookbinding bar that beyond start plate end, is provided with, prevent effectively because of falling or the effect of other external force makes and binds that bar is opened and loose leaf paper takes off.And, in the present invention, bind opening and locking of bar by rotating operation, the sort of operational sense of discomfort that makes the two ends action bars slide and finish same action and cause has not just had.In addition, rotating operation also is easy to reinforcing than slide, therefore, guarantees to insert the finger space and also just there is no need between the edge of action bars and bookbinding seat.Thereby can eliminate ring binding tool length unsuitable lengthening and and the rotating operation formula member popularized originally between disunity these defect on the size.
