Abstract
The description relates to a clamp for pages suspended in a hanging file with a basic body (1) with elongated apertures (8) for brackets (7) of the suspension device and a clamping device (6) holding the brackets (7) by means of a tensionable spring wire (9). To facilitate construction it is proposed that the spring wire (10) of the clamping device (6) which is bent into the frame (9) surrounding the relevant aperture (8) form a spring tongue (12) running on the inside of the frame at an acute angle to the longitudinal axis of the aperture (8), while the other end (14) of the spring wire holds the frame leg (11) extended to the spring tongue (12) on the outside, and the free end section (16) of the spring tongue (12) forms a spring-loaded support for the bracket (7) together with the edge of the aperture or a section of the frame (9) projecting beyond said edge in the region of the end (18) of the aperture (8) facing said end section (16).
Description
The present invention relates to a kind of hold down gag, it has one to have the matrix of the slotted hole shape through hole that is used for the suspension arrangement hook and have one by means of the clamping device of the spring steel wire that can clamp round hook.
Such general hold down gag has the matrix of a sheet metal punching press, have two to be used for the slotted hole shape through hole of two hooks of file and two spring steel wires that extend between these two through holes are arranged on the matrix, hook stretches out between their the end section that is equipped on each through hole.The here paper that should think to be used to be equipped with the hole or to be equipped with hanging ring as file, film etc. and be provided with any clip of this suspension arrangement.By means of the support wedge that is located at spring steel wire longitudinal center, before the end section, certain distance is arranged be bearing in the spring steel wire in the matrix outside, vertically strutting each other by means of such effect in the middle section, that is, make the end section turn round inwards and under the condition that corresponding friction connects, flexibly lean against on the hook around the supporting-point on the matrix.Therefore, this hold down gag can prevent to move by accident along hook by clamping device.Because the clamping force that is applied depends on the thickness of hook, and the angle of revolution of spring steel wire end section is limited, so this hold down gag can only be used in the less hook of vary in diameter scope.In addition, thus this baroque hold down gag since the load matrix that produced almost completely do not allow to make with plastics.
If adopt plastic hold down gag, the clamping device that then is used to link up with is made of diminishing slotted hole usually, and hook is clamped in the slotted hole by mobile hold down gag.Because this clamping of the hook in through hole, so this hold down gag can only be used for a kind of hook of norminal size when the pinch zones of the some other specified thickness coupling that a plurality of and hook are not set.In those hold down gags of being made up of spring U-shapeds of sealing folder similar restriction is arranged, this spring U-shaped is clipped in and forms a clamping gap that is used to pass the hook that the spring U-shaped presss from both sides between the limit that they face one another.
Therefore the objective of the invention is to avoid these shortcomings and take simple structural measure to improve the hold down gag of the described type of preface, hook also can be clamped reliably at other diameter range.
The measure that the purpose that proposes in order to reach by the present invention is taked is, clamping device bends to the spring steel wire around the framework of relevant through hole, constitute one and acutangulate the spring-latch of extension in that framework is inboard, and another spring steel wire end is enclosed in the framework face and detained outside that leg of frame that extends to spring-latch with the through hole longitudinal axis; And, the free end section of spring-latch in through hole faces that end location of this end section, with the limit, hole or with framework limit, the hole part of stretching out from then on, constitute an elasticity mount pad that is used to link up with.
Constitute and acutangulate the spring-latch of extension by spring steel wire with slotted hole shape through hole, when vertically moving, passes through through hole the hook revolution at hold down gag, in the end region of hook, flexibly be fixed in the mount pad at through hole, this mount pad constitutes between the limit, hole of the free end section of spring-latch and through hole or a frame section, and the back is this to be occurred under the situation in the porose area that this frame section stretched into through hole.Because the revolution range of spring-latch has the possibility that further expands, so this flexible mount pad can be adapted to the concrete thickness linked up with automatically.Because the framework of spring-latch and band spring-latch is made with continuous spring steel wire, so a moment part that produces when spring-latch turns round is passed to whole framework, meanwhile, that end relative with spring-latch by spring steel wire encloses and fastens that leg of frame that has spring-latch and formed very favorable structural condition, because the elastic force of spring-latch obtains the support of the framework pretightning force of being forced to produce just when spring-latch turns round, so no matter all can guarantee needed clamping force in nothing to find fault with, be without rebuke ground for thicker still thinner hook.For this reason need only be for hook provide a mount pad, various hooks can irrespectively be pressed in this mount pad with its thickness.A kind of like this mount pad can need not special structural measure and obtain in the end region of slotted hole shape through hole.In a kind of particularly advantageous form of implementation, guarantee, do the time spent when the elasticity mount pad that is used to link up with plays the spring locking groove, link up with just latchable in this mount pad, the exactly connection that matches with respect to a kind of shape of vertical formation of through hole.Whether only be connected by friction or shape connects irrelevantly suitably along through hole is fixing longitudinally with hook, the spring steel wire that curves a framework all causes the very little clamping device of a kind of structure height.
If spring steel wire in the end of spring-latch in the framework face back bending and substantially with self abreast until drawing back the leg of frame, then at first stopped the part of the through hole that is used to pass hook basically by spring steel wire end of being drawn back, thereby can avoid owing to link up with and pass the outside rotating side of spring-latch and have and make hold down gag be inserted in any possibility on the hook mistakenly by this.In addition, extending in parallel in the spring-latch zone by spring steel wire to increase effective spring force, because when the spring steel wire end bearing that draws back after on the leg of frame, for the main spring tongue, that spring steel wire section of drawing back also must overcome its spring force strain.
In order to make the framework of making by spring steel wire obtain favourable structural condition, spring steel wire can bend to the framework of a substantial rectangular, diagonal from an one long limit generally along rectangle curves spring-latch backward, so provide enough rotary spaces in this framework inside for spring-latch.Consider the revolution possibility that spring-latch is necessary, its length is compared with the diagonal of rectangle and obviously should be selected suitably shortlyer.If being in substantially parallel relationship to the long limit that is facing it of framework, the free end section of spring-latch extends, then when spring-latch turns round, between this free end section and matrix through hole end or framework, provide one be used to link up be the locking groove of wedge shape expansion towards the spring-latch extreme direction, therefore, in case hook flexibly inserts in this locking groove, just can irrespectively be clamped securely with its thickness.
For hold down gag can be clamped on the hook movably securely, should on matrix, provide a suitable fixture for the spring steel wire framework.For this purpose, can under the situation of pretightning force is arranged, pack in the insertion guide groove, insert guide groove and prevent that framework from moving transverse to the framework face transverse to matrix through hole portrait orientation by the framework of spring steel wire system.Framework inserts guide groove under the situation of pretightning force can simplify assembling, meanwhile can cancel to frame fixation required independent safeties in inserting guide groove.Insert this orientation that guide groove is used to the through hole linked up with relatively, caused framework in matrix along a kind of good supporting of hold down gag, especially under the situation of rectangular frame with respect to the hook moving direction.In order to get rid of the possibility that spring-latch sticks up simply outside the framework face, the free end of spring-latch end section also can be packed into and be inserted in the guide groove.
At last, the width of slotted hole shape through hole is chosen as less than the frame width along same orientation measurement, best 1/2nd width less than framework are so can only see a partial spring tongue of being with the end section that constitutes the spring locking groove and the part that can only see the long limit of one of them framework equally basically at the open region of through hole.Do like this and not only cause spring steel wire framework favourable fixing and less danger that is hurt in matrix, but also prevented because hold down gag is enclosed within mistakenly and causes maloperation on the hook.
The accompanying drawing illustrated object of the present invention.Wherein:
Fig. 1 is the hold down gag simplification vertical view of hand punch by the present invention in form;
Fig. 2 links up with the profile of clamping device perpendicular to the hook that will clamp;
Fig. 3 is by clamping device vertical view when thicker hook is in clamped position of Fig. 2;
Fig. 4 is when thinner hook is in clamped position and the corresponding clamping device figure of Fig. 3; And
Fig. 5 is along the section of Fig. 3 center line V-V.
As seen from Figure 1, represented hold down gag is combined into a structure member with the hand punch of the page that is used for being suspended on hanging file, it has a panel-shaped base body 1 and two fixtures 3 eyelet punch 4 and that constitute the page insertion seam 2 of will boring a hole that are used for each power that can overcome back-moving spring manipulation between hold down gag and matrix 1, a punching mating reaction in eyelet punch 4 and the matrix 1.Respectively establish an insertion guide groove 5 that is used for clamping device 6 at fixture 3 and the opposite side that inserts seam 2, its body can be clamped on the common suspension arrangement by means of this clamping device.In slotted hole shape through hole 8, pass the clamping device 6 of the hook 7 of matrix 1, constitute by a spring steel wire 10 that curves substantial rectangular framework 9, spring steel wire 10 constitutes a spring-latch 12 that extends generally along framework 9 diagonal by one of them the long limit 11 that prolongs framework 9 in that framework is inboard, this regional inner spring steel wire 10 be in substantially parallel relationship to by a back bending section 13 self ground draw always get back to 11 places, long limit till.The other end 14 of spring steel wire 10 overlays on the outside with that limit 11 of spring-latch 12, so this limit 11 can rest on this spring steel wire end 14 when spring-latch 12 revolutions.
By Fig. 2 to 4 as seen, pack into and insert framework 9 relevant through hole 8 in the matrix 1 in the guide groove 5, so the limit 15 parallel with limit 11 of framework 9 is in one of them long border area of through hole 8, and spring-latch 12 is with respect to the extension vertical in an acute angle of through hole 8.Because spring-latch 12 is made of the spring steel wire section that extends in parallel in the scope of through hole 8 and has an end section 16 that is in substantially parallel relationship to limit 15 orientations, so can hindering hook 7 in the pinch zones of clamping device, passes through hole 8, the possibility of consequently having got rid of maloperation, because link up with on 7 these sides that may insert spring-latch, promptly, spring-latch 12 constitute one along spring-latch 12 from the limit 15 revolution evolutions to that side on inlet inclined-plane of hook 7, as for example as seen from Figure 2.
If now 17 direction moves with respect to hook 7 matrix 1 from position shown in Figure 2 along arrow, then spring-latch 12 overcome spring force from the limit 15 revolutions open, in hook 7 arrives spring-latch 12 end sections 16 locations.Because for the inlet inclined-plane of spring-latch 12, spring-latch 12 end sections 16 after the revolution are to tilt in the other direction, so be pressed against slotted hole shape through hole 8 faces on that end 18 of end section 16 with linking up with 7 clampings, or be pressed against on the frame part that stretches in this district of through hole, therefore formed the elasticity mount pad of a pro forma spring locking groove for hook 7.But a kind of like this spring locking groove is not the end section 16 that trend with respect to remaining spring-latch of absolute demand is a knuckle.For this reason for example also can be in the zone on limit 15 or the long limit of the through hole 8 that limit 15 is relevant therewith regional in make a locking groove, because needed only is hook flexibly must be pressed in the locking groove by spring-latch 12, exactly by means of a power, this strength guarantees should form a kind of enough frictions connection on the hook 7 for matrix 1 immovably is clamped in.This frame structure by spring steel wire 10 can be easy to guarantee this point, because framework 9 is by pretension when spring-latch 12 revolutions, and this pretension has further been supported the clamping to hook.Comparative example such as Fig. 2 and 3 can find out immediately, because spring-latch 12 revolutions make spring steel wire section 13 strains that extend in parallel, have consequently further improved clamping force.
As seen from Figure 4, can clamp thinner hook reliably equally by means of illustrated hold down gag.Hook 7 still kayser surpasses in the spring locking groove that constitutes between the part that stretches on the limit, hole in this zone in the end section 16 of spring-latch 12 and the end 18 or the framework of through hole 8.Can not bend the framework face for spring-latch 12 when the direction of edge hook 7 is stressed, the free end 19 of end section 16 all is clamped in the insertion guide groove 5 at any rotary position of spring-latch 12.
