Description

[Detailed Description of the Invention] This invention relates to a ring binder with a lock, and particularly to a ring binder with a lock that can be locked and unlocked using a key.

A drawback of ring binders is that if a large amount of documents are bound and a shock is applied, such as by dropping a file, the ring will momentarily open slightly and one or two documents will fall through the gap. I couldn't escape it.

This invention attempts to improve this drawback by combining a ring binder and a lock body, and using a lock piece attached to the lock body,
This device holds down the tooth plate that opens and closes the ring to prevent the ring from opening momentarily even if a shock is applied to the file, and this lock body is rotated using a key to lock the file. A ring binder with a lock that can be used reliably is obtained.

To explain the figures, FIG. 1 is a perspective view of the ring binder of this invention, and FIG. 2 is a view of FIG. 1 seen from below. In the opposite direction, tooth plates 22, 23 are provided, and a suitable number of rings 24, . . . , 25, . . . are attached to the tooth plates. Therefore, operating pieces 28, 28 are provided at the left and right ends of the back plate, and when you want to open the ring, you can use the operating pieces 28, 28.
When pushed down so as to open outward, the push piece 29 at the bottom of the operating piece 28 flips up the engagement plates 22, 23 upwards, and opens the rings 24, 25 outward.

However, as mentioned above, there is a drawback that when an impact is applied to the file, the ring opens momentarily, and one or two documents inside may fall through the gap. This invention is intended to eliminate this drawback by combining a lock body as shown in FIG. 3 with a binder. Lock body 30 shown in FIG.
There is a shaft-like body 32 integrally formed with a disc 31, from which lock pieces 33 protrude left and right. The upper part of the shaft-like main body 32 is a locking protrusion 34 having a small diameter.
The lower part of the shaft-like main body 32 slightly projects downward from the disc 31 and forms a downward projecting portion 35 .

Figure 4 shows Figure 3 viewed from below.
A key hole 36 into which an insertion portion 41 of a key 40, an example of which is shown in FIG. 5, is inserted is provided in a downwardly protruding portion that protrudes downward from the disc 31.

Figure 6 shows the file, binder, and lock body 30.
It is an explanatory diagram showing a mode of combination with the second
Explaining this in conjunction with the figures, the binder is fixed to the spine 2 of the file, and the lock body 30 has a disk portion 31 between the engagement plate and the spine, and a lock piece 33 between the back and the back. The locking protrusions 34 are assembled so as to fit between the rear plates, and the tips of the locking protrusions 34 protrude slightly from the back plate.
The entire lock body is supported. (The tip of the projection 34 is shown projecting in FIG. 1.) The downward projection 35 below the disk 31 is also exposed through a hole drilled in the back cover 2, and a key can be inserted from the outside through the key hole. It is designed to be inserted into the 36.

As shown in FIG. 2, notches 26 and 27 are provided at appropriate locations in the tooth plates 22 and 23, and the central portion thereof is a thick diameter portion that is slightly larger in diameter than the shaft-shaped main body of the lock body. A lock body is inserted into the notch as shown in FIG. The appearance of the entire file is shown in FIG. 7. The file 10 consists of a front cover 1, a spine 2, and a back cover 3, and the spine 2 has a keyhole portion 4. As mentioned above, the tip of the downwardly protruding portion 35 of the shaft-like projection of the lock body 30 is exposed in this keyhole portion 4, and the insertion portion 41 of the key 40 (FIG. 5) is inserted into the keyhole 36 from the outside. It is now possible to do so.

The ring binder with a lock of this invention has the above-mentioned structure, and the lock body 30 is rotated by inserting the insertion part 41 of the key 40 from the outside of the file into the key hole 36 formed in the downward protrusion 35. It is something that makes you When the lock piece 33 of the lock body 30 is positioned along the longitudinal direction of the notches 26, 27 as shown by the solid line in FIG. 2, the engagement plate 22, 23 can move freely without being hindered by the lock piece. Therefore, if you push down the operation piece 28 so as to open it outward,
A push piece 29 at the bottom of the operation piece 28 can flip up the engagement plate and open the ring.

When you want to lock, use the key to lock 30
90 degrees with respect to the longitudinal direction of the notch, and push the lock piece 33 above the engagement plate 22, 23 as shown by the broken line in FIG. 2 and in FIG.
Since the fastener plates 22 and 23 are held down, the fastener plates will not spring upward even if an impact is applied to the file, and the ring will not open.
