Description

The locking device of lever arch type file clip

The present invention relates to binder, relate in particular to the locking device of lever arch type file clip.

In a kind of binder that widely is known as annular loose-leaf notebook, loose-leaf binder is held in the buckle-type split ring in the file.These rings are made mobilizable two halves, and two halves all are connected on the latch plate, thereby ring can buckle be opened with buckle and closed.A problem of this file is that ring may collapse out if press from both sides a large amount of loose-leaves.

In another kind of conventional, well-known is in the binder of lever arch type file clip, and loose-leaf is clipped in the file with openable arch ring.These arch rings respectively contain one first fixing element and one second movable element, and the latter can resist spring and move towards retaining element under leverage.Lever is crossed a center, thereby moving element is locked in the position of closing.

The invention provides a kind of locking device of lever arch type file clip, wherein, saved lever,, they are provided with joint element for the effect of arch ring element antagonism spring is maintained in its closed position.

Therefore, the invention provides a kind of locking device of lever arch type file clip, contain: a substrate; A pair ofly be fixed on the substrate rigidly and from the first upright arch ring element of substrate; Be installed in to pair of pivot on the substrate with the relative first arch ring element second arch ring element with respect to the motion of the first arch ring element between a position of opening and position of closing; A spring that is installed on the substrate, it for good and all act on and the second arch ring element bias voltages to the position of opening; And the joint element that on the first and second arch ring elements, is used for the effect of second arch ring element antagonism spring is remained on the position of closing.

This provides several advantages of technology formerly that surpass.At first, do not need the lever group and saving has been arranged.The second, substrate can be done narrowlyer.The 3rd substrate can be done thinlyyer.

The preferred embodiments of the present invention are described with reference to the accompanying drawings, wherein:

Fig. 7 is the cutaway view of locking device at open position;

Fig. 8,9 and 10 is end-views of locking device, the present invention is shown how can utilizes littler substrate; And

Figure 11 and 12 is side views of locking device, and the power that is applied to it is shown.

Locking device shown in Fig. 1 to 7 contains: a metal substrate 1 that is roughly rectangle; The first arch ring element of one coupled columns, 2 forms, they are rigidly fixed to two angles and upright of substrate thereon; With a pair of second arch ring element 3.The second arch ring element is linked to be integral body mutually, and is connected by a rod 4, outside 5 and a central crank section 6 that this rod has substantially the side with substrate stretch abreast.The outside 5 of rod 4 is clamped on the substrate by the tab 7 of bending, and tab 7 allows rod 4 to be pivotable around the longitudinal axis of outside 5.It is movable between an open position (being shown in Fig. 2 and 7) and a closed position (being shown in Fig. 1 and 6) with phase coupled columns 2 that thereby the second arch ring element is pivoted on the substrate.In an illustrated embodiment, the first arch ring element 2 has the bent angle portion 22 of an erection part 21 and a weak point.The second arch ring element 3 has the bent angle part 33 of an erection part 31, a sweep 32 and a weak point.

The spring leaf 8 of a steel is installed on the substrate and for good and all acts on rod 4 the crank section 6, with the second arch ring element bias voltages to the position of opening.Arch ring element 3 can resist the effect of spring 8 and moves to the position of closing with hand.The joint element of interlockable teeth 9 forms is formed on the bent angle part 22,23 of free-end of the first and second

arch ring elements

2,3, and the effect that is used to resist spring remains on the position of closing to the second arch ring element 3.For

arch ring element

2,3 being moved into, shifts out the position that engages one another, need crooked in them at least one and make it to deflect away from slightly its normal perpendicular so that tooth 9 hook or break off relations mutually.Because the second arch ring element 3 is longer than the first arch ring element 2, most of bending is born by the second arch ring element.

As shown in drawings, the tooth on the

arch ring element

2,3 is oriented to, make the second arch ring element 3 must be a little in opposite directions crooked (shown in the arrow among Fig. 4) so that tooth 9 hooks and breaking off relations.This is the arrangement of most convenient, opens arch ring easily because can press together with a handgrip arch ring element 3.In addition, can also provide another orientation, wherein, break off relations in order to make tooth, the second arch ring element 3 mutually to same direction bending.This also can carry out with a hand.

Substrate 1 can be with a single metal punching out, and comprises a upright bent tongue 10, and the latter forms the catch of the crank portion 6 of rod 4, and also is the catch of the second arch ring element 3 when the second arch ring element 3 moves to the position of opening.In this position, crank portion 6 is by the downside of spring 8 compressing tongues 10.Tab 7 and bent tongue 10 and substrate one, but spring 8 is independent components that are installed on the substrate.

Referring now to one of Fig. 8-9 explanation major advantage of the present invention.Fig. 8 shows a device formerly, and one of them lever 12 that has a roller 13 is installed in the center of substrate.The crank section that roller acts on the arm that connects the second arch ring element moves to the closed position to them with the effect that resists spring.This lever by a position of crossing the center so that the second arch ring element is locked in the position of closing.If remove lever assembly, situation of the present invention as shown in Figure 9, the width W of substrate can shorten about 10 millimeters, as shown in figure 10.

Referring now to Figure 11 and 12 another advantages of explanation.Under the condition of closing, traditional lever arch ring device as shown in figure 11 is subjected to the pressure of lever and the pressure of spring.In order to guarantee the lock function of lever, that above-mentioned opposite power F must be designed to tilt by chance rather than vertical.As a result, substrate is subjected to unbalanced power, and is compelled to do and thickly is out of shape to avoid being subjected to unbalanced power.

As shown in figure 12, there be not lever assembly and during by it pressure that causes, the substrate of lever of the present invention-arch ring device is subjected to less power F.In addition, owing to no longer need to guarantee the lock function of lever, new device designs to such an extent that be subjected to vertically and the power of balance.Thereby substrate is not yielding and can do thinlyyer.
