Description

Paper-retaining mechanism

Technical field

The utility model relates to a kind of paper-retaining mechanism, particularly, this mechanism can be fixed on the pedestal to form paper-retaining device, for example box type file or file gripping member, and the utility model also relates to a kind of paper-retaining device that is combined with this paper-retaining mechanism.

Background technology

Traditional such as paper-retaining devices such as box type file or file gripping members in, traditional paper-retaining mechanism is fixed firmly on the pedestal (as the strip of paper used for sealing of box type file or the strip of paper used for sealing of file gripping member), so that can keep paper page or leaf or other similar material page or leaf of boring a hole releasedly.

In a kind of traditional paper maintaining body of the above-mentioned type that is commonly referred to lever-arch (lever-arch type) binder mechanism, single-arm lever can pivot, so that paired arch spare is pivoted with respect to paired fixedly column piece, thereby the perforation paper can be taken out from this document clamp mechanism or is inserted in this document clamp mechanism, perhaps make column piece and arch part closure to be formed into right closed hoop, so that paper is remained in this closed hoop.Crank between this paired arch spare passes through engages, and in the pivot motion course of lever, the roller that joins on the lever moves on this crank, thereby optionally makes this paired ring open or closure.In the operating process of this traditional file clamp mechanism, lever pivots downwards so that by column piece and the paired ring closure that forms of arch part, lever upwards pivots and can allow the spring leaf pivot so that described ring is opened.

The problem of this traditional lever-arch file folder mechanism is, when lever pivots to upper to open when ring, the following side contacts of lever and one of them arch part or at least very approaching, so paper can only insert or taking-up and can not pass through the arch part by column piece insertion or taking-up.

The specific embodiment

Fig. 1 to Fig. 5 has showed the various views according to the lever-arch file folder mechanism of an embodiment of the present utility model, and this mechanism represents with Reference numeral 10 usually.This mechanism 10 comprises generally flat base 12 and the gripper shoe 14 that protrudes upward from this base 12, and described gripper shoe 14 is fixedlyed connected with described base 12.For example, described gripper shoe 14 can be formed by the same metallic plate punching press that forms described base 12.

Two pillars 16 are securely fixed on the described base 12.Paired arch spare 18 integrally forms and links together by pars intermedia 20, thereby arch part 18 and pars intermedia 20 can move each other simultaneously.Described arch spare 18 is bonded on the described base 12 by claw type anchor clamps 22, so that described arch spare 18 can pivot with respect to described pillar 16 and described base 12 between the primary importance (being called " closing position ") and the second place (being called " open position "), wherein when described primary importance, the free end 18a of described arch spare 18 contacts with the free end 16a of described column piece 16 and cooperatively interacts to form two closed hoops (at this moment described paper-retaining mechanism 10 is in " ring closure state "), when the described second place, the free end 18a of described arch spare 18 and the free end 16a of described column piece 16 are separated from each other, so that described ring is opened (at this moment described paper-retaining mechanism 10 is in " ring open mode ").

Spring leaf 24 is bonded on the described base 12, so that described spring leaf 24 can act on the described pars intermedia 20 from the below, so that described arch spare 18 is biased into open position.

Described lever-arch file folder mechanism 10 comprises lever 26, and described lever 26 comprises first body of rod 26a and second body of rod 26b of be bonded with each other (for example engaging by forming as one mutually).Fig. 6 to Figure 10 has showed each view of described lever 26, between first body of rod 26a of described lever 26 and described second body of rod 26b, form to surpass 90 ° angle beta (referring to Fig. 6), for example from 110 ° to 150 °, be preferably 130 °.Described first body of rod 26a has operating side 28 freely, by the described operating side 28 of manual operation described lever 26 is moved, thereby described lever-arch file folder mechanism 10 is moved between open mode and closure state, and this motion mode is discussed below.

Described lever 26 joins on the gripper shoe 14 by rivet 30, and described thus lever 26 can pivot around the axis P-P that is parallel to described base 12 with respect to described gripper shoe 14.Particularly, the hole 38 of second body of rod 26b of described rivet 30 by running through described lever 26 engages.Roller 32 engages with second body of rod 26b of lever 26 by rivet 34, and this rivet 34 allows roller 32 to rotate freely with respect to second body of rod 26b of lever 26.

As Fig. 1 to Fig. 4 and Figure 11 and shown in Figure 12, when lever-arch file folder mechanism 10 is in the ring closure state, roller 32 acts on the crank portion 20a of described pars intermedia 20, keep the free end 18a of described arch spare 18 to contact with the bias effect that overcomes described spring leaf 24, thereby keep described lever-arch file folder mechanism 10 to be in the ring closure state with the free end 16a of described column piece 16.When this position, first body of rod 26a of described lever 26 is positioned at the right side (as shown in Figure 1) perpendicular to the axis T-T of described base 12, and forms the inclination of 20 ° to 50 ° angle [alpha] with respect to described axis T-T, and this angle [alpha] is preferably 30 °.

For described lever-arch file folder mechanism 10 is moved to as Figure 13 and open mode shown in Figure 14, described lever 26 is pivoted to Figure 13 and shown in Figure 14 position around axis P-P by the direction shown in the arrow C (referring to Fig. 1) with respect to described gripper shoe 14, first body of rod 26a of wherein said lever 26 is positioned at the opposite side (i.e. left side as shown in Figure 1) of described axis T-T, and form the inclination of the angle identical with respect to described axis T-T with described angle [alpha], this angle is 20 ° to 50 °, is preferably 30 °.When lever 26 was in this position, roller 32 was removed from the crank portion 20a of described pars intermedia 20, thereby spring leaf 24 is subdued and acted on the described crank portion 20a from the below.Therefore described arch spare 18 pivots from described column piece 16 and opens, to open ring.

As can be seen, no matter described lever 26 positions be ring open position or ring closing position, and the free operant end 28 of lever 26 is all between two rings.By this arrangement, when lever 26 was pivoted to the ring open position, lever 26 (described specifically operating side 28) left described two arch parts 18, and paper can take out or insert by described column piece 16 and described arch spare 18 like this.

Described lever-arch file folder mechanism 10 can be for example by rivet or screw regularly or be removably installed on the pedestal (as box type file), to form paper-retaining device, described pedestal can be made by metal, metal alloy, hardboard or other similar material.

Should be understood that an embodiment that can implement according to the utility model is only illustrated and described to foregoing, the modification or the change that do not break away from the utility model design all should be considered in the utility model scope.Each technical characterictic of the present utility model that describes in the context of single embodiment for simplicity can be provided with individually also and can be provided with in the mode of the sub-portfolio of any appropriate.
