Problems solved by technology

[0005] However, in the above-mentioned locking structure, when the clamp ring is closed, it is necessary to push down the second driving member 11 with fingers so that the engaging portion 18' is engaged on the engaging projection 15, which is cumbersome.
[0006] And, in the above structure, there is a problem to be solved, that is, since the second driving member 11 can figure 1 and 4 Free pivoting between the two states shown, so that the lock may be released when a light external force is applied during transport or the like

Embodiment

[0039] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In order to facilitate the understanding of the present invention, in this embodiment corresponds to Figures 1 to 4 Those parts of the prior art shown are denoted by the same reference numerals.

[0040] Figure 5 is a plan view of a binder with a locking member according to the present invention. Image 6 and 7 respectively Figure 5 Left and right side views of the binder shown.

[0041] Figures 8 and 11 are enlarged front views of one end of the binder with locking member in the closed and open states, respectively.

[0042] A first and a second long base plate 1 and 2 abutted against each other on their inner sides each have a plurality of semicircular clamp rings 3 and 4 integrally formed therewith. On the outer edges 21 and 22 (Fig. 8(a)) of the two base plates 1 and 2, an elastic casing 7 limiting the outer edges is set, and this elas...

Abstract

In order to prevent accidental opening of the rings of a binder, a locking member (44) includes integrally comprising a pivotable portion (56), an engaging projection (46), an elastic portion (52) and a finger A part of the hook portion (58); the pivotable portion (56) is pivotally installed in a first driver (10); the engagement projection (46) and a second driver (11) An engaging recessed portion (38) of an engagement, to prevent the second driving member (11) from moving; the elastic portion (52) is against an upper surface of a first base plate (1), for engaging the protrusion ( 46) push to engage the recessed part (38); thus, in a state where the clamp rings (3) are closed, an opening force acting on the clamp rings (3, 4) is overcome to prevent the two substrates (1, 4) from 2), and, when one finger-like hook (58) is pushed toward the other finger-like hook (20), the elastic force of the elastic portion (52) is overcome to make the engagement protrusion (46) disengage from the second driving member (11), then move the two base plates (1, 2) in such a direction that the clamping rings (3, 4) are opened.

Description

technical field [0001] The present invention relates to a type of binder in which the rings are elastically opened and closed by means of an actuating member, and more particularly, the present invention relates to a binder with a lock to prevent damage to the rings during transport, display and storage. Unexpected detachment of leaflets caused by accidental opening. Background technique [0002] Quite often, the leaves of the binder are accidentally disengaged due to the unintentional opening of the rings caused by vibrations or shocks applied during handling such as transport, reloading, exhibition, storage, etc. In order to eliminate this unexpected phenomenon, the inventors of the present application proposed a binder with a locking structure in Japanese Patent Publication No. 88,680 / 1993. Briefly, as Figures 1 to 4 As shown, the disclosed binder includes: a first and a second base plate 1 and 2 abutting against each other on their inner sides, each base plate having a...
