Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for preventing the natural release of binding nails in a binder.

[0002]

[Prior art]

 The release of the circular arc-shaped binding claws, which are bound in a semicircular shape in the binder, is mainly caused by the tilting action of the operation piece provided at the longitudinal end of the binder or by reversing the warping action of the main body in which the binding claws are implanted. The main form is that the opening action is given by the action, but in any case, the opening / closing operation of the binding claw can be performed as needed.

[0003]

[Problems to be solved by the device]

 Originally, the binder was designed so that the morphology, that is, the opening action and the closing action, which were obtained by the action given to the binding nail, could be sustained until the opposite action given next. The basic technical configuration is that the force of an arc-shaped curved line that bulges upward due to the compressive stress due to the back plate clinging acts on both sides of the main body in which the binding claws are planted, and its cross-sectional shape changes to the bridge form. This is a completely opposite form. It acts with two extreme forms in which the force of a downward-pointing arc curve acts, and we do not expect a horizontal state at the midpoint at all, and it is theoretically possible. Absent.

Most of the binders made by the above-mentioned conventional technique press the outer circumference of each binding claw to separate the binding claws from each other when the binding claws are closed to form a semi-annular shape. Although the tips are joined together, even in the closed state, there are many cases in which the closed binding claws are opened due to external pressure or impact, and the locked paper pieces are separated from the binding claws and become difficult.

The above-mentioned many cases of the spontaneous release of the unintended binding nails often occur in the distribution stage before reaching the consumer.

In one example, a plurality of binders are most frequently generated in a single packaging box, and particularly tend to occur frequently during transportation when the open page is on the lower side.

The shape of the intervening paper pieces in one binder is generally smaller than that of the binder cover, and when these open pages are on the lower side, the weight of all the intervening paper pieces is on both outer sides. It is supported by the cover.

In such a state, the load when the package is dropped from the air (even at a slight height) is applied to the binding claws all at once, and the binding claws are immediately impacted by these moments. Is opened, and all of the intervening paper pieces deviate from the binder.

Once in such a state, when the binder is taken out from the package, these are scattered all at once, and the value as a product is lost.

In view of this, the present invention adds a lock mechanism in addition to the opening / closing mechanism of the binding claw in the bander, and unless the lock mechanism is opened, the binding claw may naturally open even if it receives any impact. The purpose of the present invention is to provide a device that can be prevented.

[0018]

[Action]

 The basic opening / closing operation of the binder of this invention is the same as that of a general binder.

That is, when the front ends of the respective binding claws 3 are separated from each other and are opened, the back surface of each arc-shaped binding claw 3 is pressed and the binding claws 3 are planted. The upward arc of the main body 2 is converted into the downward arc through the horizontal state against the elastic force of the back plate 1, and the tips of the respective binding claws 3 are brought into close contact with each other to complete the binding operation.

Since the main body 2 holds the shape of either the upward arc or the downward arc as described above, when the arcs are converted, the main bodies 2 that have been joined are always in a horizontal state. Circular arc conversion cannot be performed without passing through it. By utilizing the elasticity which is the characteristic of the back plate 1 in this horizontal state, the pivot parts that are held between the outer sides of the main bodies 2 and 2 are widened. Passing the horizontal state.

Further, the operation of opening the closed binding claw 3 is performed by bringing the open / close handles 4 and 4 standing upright at the ends of the main bodies 2 and 2 and crossing each other close to each other. The downwardly arcuate main bodies 2 and 2 are converted into upward arcs via the horizontal state, whereby the tips of the binding claws 3 are separated from each other and are opened.

The above-described operation is the known opening / closing operation in the opening / closing handle type binder and the operation thereof.

However, the principle structure is such that the tip of the binding claw 3 is not brought into contact with or separated from the binding claw 3 unless the opening / closing operation is performed, but in reality, the unexpected open phenomenon occurs. .

Therefore, in the present invention, by utilizing the material-like elastic property of the opening / closing handles 4 and 4, the locking projections 5 and the locking parts 6 are provided at the close positions in the intersecting parts that cross each other, and the closing handles are closed. When the operation of opening the binding claw 3 is performed, the opening / closing handles 4 and 4 that are brought close to each other are given a twisting action against the elasticity of the material characteristic as shown by the arrow in the rotating direction of FIG. , By releasing the coupling action of the locking projection 5 and the locking portion 6 to release the lock operation and imparting the close action to this, the main bodies 2 and 2 are arced upward from the downward arc. Is converted to a space between the tips of the binding claws 3 to give a separating action.

The opening / closing handles 4 and 4 which are always formed in a close contact with each other in a cross shape have the locking projections 5 on the sliding surfaces which are crossed and joined when the tips of the binding claws 3 and 3 are in a separated state. By intervening, it resists the elasticity of the material characteristics. From this state, if the tips of the binding claws 3 are guided to the joint with external pressure, the locking projections 5 move the sliding surface of the opening / closing handle 4 on the other side. At the time of sliding and disengaging from the locking portion 6, the sliding surfaces of the respective opening / closing handles 4 and 4 come into contact with each other, and at the same time, the locking projection 5 meshes with the locking portion 6 to perform the unlocking operation. Unless otherwise specified, spontaneous unlocking is prohibited.

As described above, when the closed binding claw 3 is opened, the lock must first be released. At that time, the unlocking operation is the operation before the phase approaching operation of the open / close handles 4 and 4. In the procedure to be performed, a twisting action is given to the open / close handles 4 and 4. At this time, the surface is pressed against the finger-holding pressing portions 4a, 4a on the open / close handles 4 and 4 and is twisted in one direction. The finger hook pressing portions 4a, 4a are twisted in a state where the upper portions of the opening / closing handles 4, 4 are twisted, and the pressing surfaces are easily subjected to a twisting pressure by a finger. 4b and 4b are provided so as to face each other in the rotating direction.

As described above, as another feature, the pressing surfaces 4b and 4b are provided so as to face each other in the rotating direction in the finger-holding pressing portions 4a and 4a above the opening / closing handles 4 and 4, as described above. It is a silent suggestion to the purchaser who gets this binder for the first time, how to use it, with the configuration shape.

[0028]

[Example of device]

 Next, with reference to the drawings, an embodiment of the present invention will be described. A back plate 1 made of a material having elasticity having a width dimension between both side edges is a main body which is locked inside the both side edges. Width 2 is a dimension slightly larger than the widthwise normal dimension of the back plate 1, and a plurality of binding claws 3 with their tips facing each other and separating and contacting are provided on the upper surface to form an arc shape in the width direction. , This is divided into two in the longitudinal direction, and the inner sides of both are abutted to form a single body, and both outer sides of the integrally formed main bodies 2 and 2 are formed on both sides of the back plate 1. In the binder A, which is installed inside and is united to also function as a pivot, the opening and closing handle 4 for opening and closing the binding claws 3 of the binder A is arranged vertically from one end of the main body 2, In addition, it is formed with a cross shape that enters the area on the extension line of the relative surface members to each other. To have.

Each of the opening / closing handles 4 and 4 may be individually formed and fixed to the ends of the main bodies 2 and 2 as described above, or integrally formed at the ends of the main bodies 2 and 2. The opening / closing handles 4 and 4 and the main bodies 2 and 2 may be combined as desired.

The open / close handles 4, 4 configured as described above are not limited in terms of material type, but at least a material having elasticity as a characteristic is most suitable for the material used, and therefore, a hard synthetic resin is used. Alternatively, a metal plate is a suitable material.

As described above, each of the opening / closing handles 4 and 4 stands upright in the vertical direction from the longitudinal ends of the main bodies 2 and 2, and the upper portions thereof are located in the areas in the extending direction of the main body 2 facing each other. The opening / closing handles 4 of the main body 2 which are formed in a slanting shape to enter each other have a symmetrical structure similar to the above. Therefore, both the opening / closing handles 4 and 4 have an intermediate position in the height direction. Cross at.

The above-mentioned intersecting portions are assembled in such a relationship that a surface sliding action is generated between them.

As described above, the open / close handles 4 and 4 intersect at their intermediate portions and form a surface contact form with each other at the intersecting portions, and a lock mechanism is formed at these surface contact points. Is.

The lock mechanism mainly has a concave / convex or meshing relationship, and depending on the case, both of them may be provided side by side.

These lock mechanisms press the back surfaces of the binding claws 3 and 3 to operate the binding claws 3 and 3 when the separated binding claws 3 and 3 are operated in the closed state in the same manner as in the previous closing operation. If the operation of connecting the tips of 3 is performed, the lock mechanism is automatically locked at the same time.

When opening the closed binding claws 3 and 3, the opening operation due to the close proximity of the open / close handles 4 and 4 is made impossible by the lock mechanism. It is configured so that the release operation must be performed.

The two open / close handles 4 and 4 form a close contact state in which they slide when being operated at the crossing portion due to their material characteristics and configuration, and the operation at the time of unlocking is in a separated state from the close contact state. By operating so that the engaging projection 5 and the engaging portion 6 are connected to each other by pulling them apart against the inherent elasticity of the opening / closing handles 4 and 4, they can be released. is there.

The locking mechanism formed by the locking projection 6 and the locking portion 6 is roughly classified into two modes.

The first mode is to form sliding surfaces that are in close contact with each other at the intersection of the open / close handles 4 and 4.

The second mode is to form the edges of the sliding surfaces that are in close contact with each other at the intersection of the open / close handles 4 and 4.

In addition, the above-mentioned modes 1 and 2 may be provided together.

In the first aspect, the convex portion 5b is projected to the sliding surface side of one of the sliding surfaces that are in close contact with each other at the intersection of the open / close handles 4 and 4.

The convex portion 5b is a steel ball 5c, and the steel ball 5c is pivotally attached at a set position of the sliding surface of the opening / closing handle 4 so as not to be detached and to be rotatable, and the ball head is slid on the sliding surface. It may be mounted so that it projects to the side.

The engaging portion 6 corresponding to the protruding portion 5b or the steel ball 5c that protrudes toward the sliding surface side has a substantially semi-annular shape in which the tips of the binding claws 3 are joined. The engaging portion 6 is provided to receive the engaging surface 5a of the engaging projection 5 at the time of forming.

A recess 6 a or a through hole capable of receiving a protruding portion protruding from the sliding surface is provided as a locking portion 6.

In either one of the two opening / closing handles 4, 4, a locking projection 5 having a surface facing the original end side thereof as a locking surface 5a near the upper side on the sliding surface side described above. And a locking portion 6 that receives the locking surface 5a of the locking projection 5 at the time when the tips of the binding claws 3 are joined to form a substantially semi-annular shape in the other open / close handle 4. Is provided.

Further, without providing the locking portion 6 for receiving the locking surface 5a of the locking projection 5 described above, the locking projection 5 is symmetrically provided on the other opening / closing handle 4 as well. In the same manner as described above, it is also possible to configure the engaging surfaces 5a of the binding claws 3 and 3 to engage each other when the tips of the binding claws 3 are joined to form a substantially semi-annular shape.

Furthermore, the upper portions of the opening / closing handles 4 and 4 are finger-holding pressing portions 4a and 4a, and the two fingers when unlocking the opening / closing handles 4 and 4 are used to twist the opening / closing handles 4 and 4. The pressing surfaces 4b, 4b capable of receiving the rotating pressing force are provided so as to face each other in the rotating direction.

[0049]

[Effect of device]

 As described above, according to the present invention, when the opening / closing member used during the opening operation of the substantially semi-annular binding claw is the cross type with the two opening / closing handles, the opening action of the binding claw can be obtained by reducing the gap. In the case where the mold is unlocked by the impact of an external force contrary to the above-mentioned intention, this invention proposes to open and close the two open / close handles by twisting them against the elastic rigidity of the material characteristics. First of all, unless the lock mechanism is released, the gap between the opening and closing handles cannot be reduced, so that there is the effect that it is possible to eliminate any unintended natural unlocking.
