BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binder steel ball, and more particularly, to an improvement of a lock fixing mechanism of a binder steel ball.

As shown in FIG. 8, the longitudinal edges of the two plate-shaped elongated members 5 and 7 each including a plurality of iron ring members constituting the coincidence-type iron ring 3 are respectively shown. Forming abutting portions to face each other, the long outer edge of the plate-shaped elongated member is restrained by the sheath-shaped elastic member 4, and the plate-shaped elongated member is opened and closed to open and close the iron ring. The binder iron ball 1 is widely used. However, in order to open the iron ring 3, the binder iron ball 91 first pulls the finger pieces 9 and 11 integrally formed on the two plate-shaped elongated members 5 and 7 to each other. The operation of opening the iron ring 3 is performed, and the iron ring is directly closed with a finger to close the iron ring 3.

As another method, as shown in FIG. 9, the lever piece 8 instead of the finger operating pieces 9 and 11 is disposed at one end or both ends of the elongated member, and this is a sheath-shaped elastic member ( 4) is mounted on. In this case, a step of attaching the lever part to the sheath member 4 at the time of assembling the sheath-shaped elastic member, and adjusting the movement of the lever so that a proper opening force is generated during assembly.

In the conventional binder steel ball shown in FIG. 8 and FIG. 9, generally, the insulated tous-life etc. may be inadvertently opened by self-weight or external vibration, etc. during the storage or shipment before shipment. As a countermeasure, it may be considered that the elasticity of the bag-shaped elastic member 4 is increased, but if it does so, the force required for opening and closing becomes relatively large, making opening and closing difficult, and the sound upon closing is also very loud. The problem arises.

Accordingly, it is an object of the present invention to provide a binder iron ball having a lock mechanism capable of reliably preventing undesired opening due to external force or self weight of an iron ring. In addition, the present invention is to provide a binder iron ball easy to open and close operation.

Between the first position of closing 16 and the second position of opening the iron members 14 and 16 by moving the elongated members 18 and 20 upward. To be rotated And a first engaging portion 36 formed at at least one end of the loose member 18, 20 and the lever structure portion 10, the first position being formed in the lever structure portion 10. The lock can be locked to the engagement portion 37 (or (37 '), (37 ″) of the elongated member (18), (20) at the same time when the lock is moved to the second position The locking mechanism of the iron ring is provided by a binder steel ball, which is provided with a lock fixing mechanism including a lock fixing portion 38 (or (38 '), (38 ″) that releases the fitting portion 37. Can be reliably prevented.

More specifically, the engaging portion formed on the elongated member is an upper surface of the end portion of at least one elongated member, and the lock fixing portion formed on the lever structure portion is at least one protrusion or (2) of the elongated member. The engaging portion formed on at least one end portion is a member standing up on the end surface of the elongated member, and the lock fixing portion formed on the lever structure portion is at least one protrusion, or the engaging portion formed on the elongated member. It is a member standing on the end surface of the elongated member and a protrusion protruding therefrom, and the lock fixing portion formed in the lever structure portion may take any other form such as being fixed to the protrusion.

Further, the lever structure portion is preferably a hole extending from the inner edge of the two plate-shaped elongated members 18 and 20 to the inside of the plate-shaped elongated members 18 and 20. 22), 24 and lever members 30 provided on both sides with rod-shaped portions 26 and 28 at two relative angles that can be loosely inserted into the holes 24, respectively. The two rod-shaped portions 26 in the state in which the lever member 30 inserts the two rod-shaped portions 26 and 28 into the holes 22 and 24 of the elongated member. The plate-shaped elongated member is caused to move up and down by rotating with the axis and 28 as the axis.

The binder steel ball having the lock locking mechanism according to the present invention having the above-described configuration is rotated by levering the lever member 30 on the rod-shaped portions 26 and 28 in the principle of lever, and thus the flat-shaped member ( When the 18 and 20 move downward, the iron ring members 14 and 16 are closed to each other. At the same time, the lock fixing portion formed on the lever member 30 engages with the locking portions of the elongated members 18 and 20 so that the lock is fixed, and inadvertent opening of the iron ring is reliably prevented.

Example 1

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 7.

1 shows a binder iron ball 12 including the lever structure portion 10 of the present invention. As shown in the figure, the binder iron balls 12 are formed of two plate-shaped elongated members 18 and 20 integrally formed with a plurality of iron members 14 and 16, which are laminated to form iron rings, respectively. It is possible to open and close the iron ring by abutting along the longitudinal connecting portion 32, and moving the longitudinal connecting portion 32 up and down with the longitudinal outer edge thereof as the axis.

The lever structure portion 10 includes holes 22 and 24 formed at a predetermined length in the transverse direction of one end portion in the longitudinal direction of the plate-shaped elongated members 18 and 20, and these holes 22 Lever members which are preferably integrally formed sideways with rod-shaped portions 26 and 28 (see FIGS. 2 to 4), respectively, which can be loosely inserted into (24) (see FIG. 4). 30).

2 shows a front view of the lever member 30 in the closed state. The lever member 30 generally has a T-shaped kita and a shape that is easily operated by a finger. In addition, the diameters and lengths of the rod-shaped portions 26 and 28 are selected so that they can be loosely inserted into the holes 22 and 24 formed inside the plate-shaped elongated member. Each of the rod portions 26 and 28 has a first position and a first position in which the plate-shaped jagged members 18 and 20 are closed with the iron rings shown in FIGS. 1 and 4. As shown in FIGS. 2 and 3, the angles α and β are mutually mutually in the front and planar projections as shown in FIGS. 2 and 3 so as to move the 6-degree iron ring up and down between the opened second positions. The attachment is made. Generally, the angle α is around 160 ° and the angle β is around 146 ° with the iron ring closed, but other angles are applicable. The angle is changed by rotating the lever member 30, but the lever member itself is maintained in a fixed relationship.

4 to 7, by operating the lever structure portion 10 according to the present invention, the two plate-shaped elongated members 18 and 20 are thus connected to the ring members 14 and 16. The situation of opening and closing with one touch is displayed.

Referring to FIG. 4, the lever member 30 is positioned with a technique position orthogonal to the longitudinal direction of the two plate-shaped main drains 18 and 20. As shown in FIG. In this case, the two plate-shaped elongated members 18 and 20 extend along the longitudinal angle α of the rod-shaped portions 26 and 28 of the lever member as shown in FIG. Positioning is carried out as shown in the first position where the flock collection part 32 protrudes downward. In this first position, the iron ring members 14 and 16 constitute closed iron rings, each of which has joined the end portions.

The portions adjacent to the lever member 30 at each end of the two plate-shaped elongated members 18 and 20 extend partially in the longitudinal direction to constitute the extended portions 34 and 38. . On the other hand, in the lever member 30, the engaging portion 17 and the lock fixing portion 38 (in this case, the engaging projection) on the upper surfaces of the extended portions 34 and 36 are in the standing state. By engaging with each other, it is effectively prevented that each of the plate-shaped elongated members 18 and 20 is opened by the sub-circumference or by its own weight such as a reinforcement loose leaf.

6 and 7 illustrate a state in which the lever member 30 is rotated approximately 60 degrees in the horizontal direction from the standing position shown in FIGS. 4 and 5.

In this rotation, the lever member 30 has its plate-shaped portions 26 and 28 at a certain relative angle as described with reference to Figs. The center positions of the two rod-shaped portions coinciding with the longitudinal joints 32 of the members 18 and 20 are the sheath-shaped elastic members 13 of the plate-shaped elongated members 18 and 20. With the long outer edge supported as the support point of the lever, it moves up and down as shown in FIG. 6 or 7. Referring to FIG. 7, in the closed state with the iron ring, the centers of the rod-shaped parts 26 and 28 were 32 'and the end was 42'. At the time of movement, it moves to the position of the numbers 32 and 42, respectively, and the plate-shaped jagged members 18 and 20 are forcibly opened. In order to allow this movement, the holes 22 and 24 are made of a long toweler which is smooth in the longitudinal direction of the elongated member at the inner edge and can slide with the rod-shaped members 26 and 28, The outer edge is formed in a circular shape that restrains the ends of the rod-shaped members (26) and (28). Alternatively, the inner edge may be circular and the outer edge may be a long ellipse.

The two plate-shaped elongated members 18 and 20 knock down the lever member 30 in the horizontal direction as described above, so that the longitudinal connecting portion 32 of the rod-shaped portion 26 and Along with the angle slightly larger than the horizontal angle β of (28) (angle β when the lever member 30 falls 90 °), it is positioned at the second position projecting upward as shown. In this second position, the free ends of the iron ring members 14 and 16 are spaced apart from each other, whereby separation or insertion of a loose leaf or the like becomes possible.

Example 2

See FIGS. 10 and 11. In this example, there are no standing portions 34 and 36 in the previous example, and the engaging portion 37 'constituted by the upper surface of the end portions of the plate-shaped elongated members 18 and 20 in the lever member 30. ) To form a lock fixing portion 38 'consisting of protrusions that directly engage. The operation is little different from the previous example.

Example 3

See FIGS. 12 and 13. In this example, projection-shaped engaging portions 37 ″ are formed in the standing extended portions 34 and 36 at the ends of the plate-shaped elongated members 18 and 20, while lever members 30 are formed. In place of the projections, a lock fixing part 38 " consisting of a long hole is formed. In Example 1, the relative relationship between the members is only reversed and the operation is almost the same.

While the present invention has been described with reference to specific examples, it is to be understood that many changes can be made within the present invention.

According to the present invention, it is possible to reliably prevent opening of the ruth leaf during the storage or transport of the binder iron ball due to its own weight or external force. In addition, even if the elastic force of the sheath-like elastic member is strong, it is possible to reliably prevent accidental opening during closing of the iron ring. Further, according to the preferred embodiment, in addition to the lock operation, the opening and closing operation of the binder steel ball can be performed by only the lever mechanism, which is simpler than the prior art.

Despite the strength of the elastic force of the sheath-forming elastic member, it is possible to prevent the unexpected opening of the iron ring when closing the iron ring.
