Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a locking device for a binder binding device.
More specifically, the present invention relates to a type of binder binding device in which binding rings are elastically opened using an operating knob.

The present invention uses a mechanism that locks the binding ring but does not lock the operating knob to prevent loose leaves from falling off accidentally due to vibrations and impacts during transportation.

(Prior Art and Its Defects) Conventional binder binding devices of the type to which the present invention is applied may fall off from the binding rings due to vibrations or shocks applied during transportation, transshipment, or other operations. Therefore, it would be good if the binder binding tool could be locked so that it cannot be opened until it is displayed at the store.

1 to 4 show a type of binder binding device to which the present invention is applied. The binding device has a plurality of binding rings 3 and a plurality of binding rings 4 that can freely abut each other, respectively, and a pair of substrates 1 and 2 whose inner sides abut each other, and both outer sides 5 of the substrates 1 and 2. , 6 are restrained by projecting edges 8, 9, and operation knobs 10, 11 fixed to the substrates 1, 2 and intersecting with each other at at least one end of the two substrates.
(and the knobs 10' and 11' at the other end as the case may be) are the basic components. The operating knobs 10 and 11 act only in the direction of opening the binding rings 3 and 4 when force is applied inward with fingers. The opening of the binding rings 3 and 4 is regulated by stop pieces 12 and 13 formed at the bottom of the abutting inner sides of the substrates 1 and 2.

In this prior art binding device, loose leaves (sheets with perforations) are bound during transportation, etc., so external force may be applied to the binding ring, causing the board to swing in the direction of opening, causing accidental damage. There were problems such as loose leaves sometimes falling off, making display work time-consuming. In response to this, the present inventor proposed that locking pawls that do not lock in the normal ring-closed state be fixed to both operating knobs, and that these pawls be locked with each other by further pressing the operating knob in the ring-closed state. did. Although this method ensures reliable locking, general users do not know how to release the lock, so it is necessary to release the lock before displaying the product at a store, which poses the problem of requiring time.

(Object of the Invention) Accordingly, an object of the present invention is to provide a binder binding device in which the binding ring is locked but the operating knob does not need to be locked.

(Summary of the Invention) The present invention has a plurality of binding rings that can freely abut each other, and a pair of first and second rings that abut each other on the inner side.
a substrate, an elastic sheath restraining both outer sides of the substrate, and a first
and a binder binding device comprising first and second operating knobs that are respectively attached to a second substrate and formed to intersect with each other, characterized in that the first operating knob is fixed to the first substrate, and the second operating knob is is pivotally attached to the second board, the first operating knob has a locking protrusion, and the second operating knob has a locking piece that can be locked to the locking protrusion by pivoting in the locking direction; Further, the locking piece is configured to be unlocked by pivoting the second operating knob in the ring opening direction.

According to the present invention, since the first operating knob can swing in the closed state, it can be in either the locked or unlocked position, and even if it is locked at the time of shipment, it can be unlocked before displaying it at the store. There's no need to.

(Specific Description of the Invention) Next, the present invention will be described in detail with reference to Examples. Note that the relationship between the first substrate and the second substrate may be reversed. Further, although the case where the locking device is formed only at one end of the binding device will be explained below, it may be provided at both ends.

EXAMPLE Reference is made to FIGS. 5 through 8, each showing one end of the binder binding device in a closed state. FIG. 5 is a front view in the locked state, FIG. 6 is a plan view thereof, FIG. 7 is a sectional view taken along line BB in FIG. 6, and FIG. 8 is a front view in the unlocked state.

In these figures, the binder binding device has a first plurality of binding rings 3 and a second plurality of binding rings 4 that can freely abut each other, and a pair of binding rings that stand along the outer edge and abut against each other on the inner edge. A first substrate 1 and a second substrate 2, an elastic sheath 7 that restrains both outer sides of the substrates, and an elastic sheath 7 that is attached to the first substrate 1 and the second substrate 2 at one end of both substrates and is formed to intersect with each other. A first operating knob 11 and a second operating knob 10 are plate-shaped.
has. The above configuration is similar to the known example.

According to the present invention, the base of the first operating knob 11 is fixed to the first substrate 1, and the base of the second operating knob 10 is fixed to the shaft or pin 14 near the outer edge of the second substrate 2.
It is pivoted by. The upper sides of both operating knobs form an inclined surface that gradually becomes higher toward the other operating knob. A locking protrusion 15 is integrally formed on the upper edge of the first operation knob 11.
The left side of 5 is upright. Correspondingly, the second operation knob 10 has an integral locking piece 16 that can engage with this upright side of the locking protrusion 15. When the second operation knob 10 is pressed in the ring closing direction (counterclockwise in FIG. 5), the locking piece 16 engages with the locking protrusion 15 to be in the locked state shown in FIG. By pressing the second operating knob 10 in the clockwise direction in the figure, it can be pivoted about the shaft 14 to release the lock.

Furthermore, the first operating knob 11 is provided with a limiting protrusion 17 that projects above the upper side of the second operating knob. In the closed state shown in FIG. 5, this limiting protrusion 17 has a sufficient gap between it and the inclined upper side of the second operating knob 10 to allow pivoting for locking and unlocking the second operating knob 10. ing. Although this limiting protrusion 17 does not allow any further swinging,
This is to apply force from the second operating knob 10 to the limiting protrusion 17 in order to move the substrates 1, 2 to the release position against the elasticity of the sheath 7.

Figures 9, 10 and 11 show other examples of the invention. In this example, the locking protrusion 1 of the first operation knob 11
5 has a recess 20 as shown in the figure, and the tip of the locking piece 16 of the second operation knob protrudes further as a projection piece 21 than the tip 22 in the previous example, and this As shown in the figure, it fits into the recess 20 when in the locked state. According to this example, since the protruding piece 21 is restrained by the recess 20, a more reliable locking effect can be obtained.

(Operations and Effects) In the above configuration, it is first assumed that the binder binding tool of the present invention has a binding ring similar to that shown in FIG. 4 in an open state.

From this state, when the binding rings 3 and 4 are pressed in mutual directions after the loose leaf has been inserted, the substrates 1 and 2 move elastically and enter the closed ring state shown in FIG. 8. At this time, the locking piece 16 of the second operating knob 10 is caught on the top of the locking protrusion 15 of the first operating knob 11. Then, when the second operating knob 10 is pushed down, the operating knob 10 pivots around the shaft 14, and the locking piece 16 firmly and frictionally locks on the vertical side of the locking protrusion 15.
- The lock state shown in Fig. 7 is reached. In this state, the binding ring 3,
Even if an external force is applied in the direction to open the board 4, the force that tries to swing the board in the opening direction acts in a direction that strengthens the locking force between the locking piece 16 and the locking protrusion 15.
The lock cannot be removed.

If you want to open the binding ring, use both knobs 10 and 11.
When you press in the mutual direction, first the second operation knob 10
pivots about axis 14 to the position shown in FIG.
When pressed further, the pivoting of the second operating knob 10 is restricted by the limiting protrusion 17, so the force applied to both operating knobs acts as a force that elastically rotates the base plates 1 and 2 in the ring-opening direction. In this way, loose leaves can be replaced.

Next, when the user closes the binding ring, it will return to the state shown in Figure 8, but there is no need for the user to lock it from this state, and even if the user locks it, there is no need to open or close the binding ring. It's not a hindrance.

As described above, the present invention provides a binder binding tool that does not interfere with the opening and closing operations of the binding rings, but can prevent the binding rings from being opened accidentally.
