[Means for Solving the Problems]

 The binder for documents according to the present invention is a binder for documents that is configured to open and close the binding ring by swinging up and down of a pair of splash plates fitted to swing against a frame. A through hole provided at both ends, an opening provided at both ends of the bounce plate over both the bounce plates, and a longitudinal direction of the frame provided at the lower surface near the both ends of the frame. An engagement groove which is opened downward in a direction orthogonal to the opposite direction, and two operation levers, and both end portions of the arm portion extending to both sides from a tip end portion of a neck portion bent from a tip end portion of the operation lever have both rebounds. Projections that can be engaged with the through holes of the plate from above are formed, and an upwardly protruding portion that can be engaged with the aforementioned protruding engagement portion at the end of the upright operation of the operating lever is provided at the center of the upper edge of the arm portion. From the center of the arm, opposite the operating lever. And Katachi設 an inverted T-shaped tip central portion is refracted in the direction can be fitted into the opening of both the splash plates, mounted for raised or lowered to both said operating lever 5 at both ends of the frame.

[0006] According to the above configuration, when the operation levers are raised from the state where both operation levers are tilted and the binding ring is opened, the protrusions at both ends of the arm are engaged with the through holes of both the bounce plates. At the same time, both ends of the inverted T-shaped tip come into pressure contact with the lower sides of both sides of the opening between the spring plates, and the binding ring closes while the spring plates swing downward. At the end of the upright operation of the operating lever, the protruding portion 9 on the operating lever side protrudes from the frame with both ends of the inverted T-shaped tip pressed against the lower sides of both sides of the opening between the two bounce plates. By engaging with the engaging portion 10 from below, the closed stapling ring is locked well, and the operating lever itself is securely fixed so as not to fall down by a small external force without fail. Click.

Therefore, there is no danger that the operation lever will fall down unexpectedly and the lock will be released and the hand will be pinched, and since the lock is possible, the engagement force of the binding ring is reduced. This eliminates the need for strengthening, and can provide a highly safe binder for documents that women and girls can easily handle.

Although 20 sets of binding rings are provided and configured, for example, binders having 2 holes, 4 holes, 26 holes, 30 holes, and the like are similarly configured.

A pair of rebounding plates 2a, 2b to which the ends of one of the binding rings 3a, 3b are fixed are rocked inside the frame 1 attached to the inside of the spine of the file. The binding rings 3a, 3b are configured to open and close by swinging up and down of both spring plates 2a, 2b, and through holes 4a, 4b are formed at both ends of the spring plates 2a, 2b, respectively. An opening 7 having a fixed width is formed in a portion between both the through holes 4a and 4b and between the two through holes 2a and 2b at both ends of the both splash plates 2a and 2b. On the lower surface in the vicinity of both ends of the body 1, a lower surface which is opened downward in a direction perpendicular to the longitudinal direction of the frame 1 and is narrower and lower than the frame 1 on the free end side of the frame 1 is provided. A raised engagement portion 10 connected to 11 is formed.

The operation levers 5 are attached to both ends of the frame body 1 so as to be capable of being turned upside down. As shown in FIG. 6 or FIG. At both ends of an arm portion 5b extending to both sides from the end portion of the neck portion 5a, projections 6a, 6b which can be engaged with the through holes 4a, 4b of both the bounce plates 2a, 2b from above are formed respectively. At the center of the upper edge of the arm portion 5b, it projects upward and can be engaged with the raised engagement portion 10 of the frame 1 at the end of the upright operation of the operation lever 5, and its outer periphery is rounded. An upward ridge 9 having a mountain shape is formed.

However, on both ends of the frame 1, the protrusions 6a and 6b on the operation lever 5 side engage with the through holes 4a and 4b of the spring plates 2a and 2b from above, respectively, and form an inverted T-shape. The operating levers 5 and 5 are respectively mounted so that the central portion of the tip 5c can be fitted into the opening 7 and both end portions 8a and 8b of the tip 5c can contact the lower sides of both sides of the opening 7.

As shown in FIG. 10, the operation lever 5 is tilted down, and as shown by phantom lines in FIG. While both ends 8a and 8b of the front end 5c are pressed against the lower sides of both sides of the opening 7 between the two bounce plates 2a and 2b, both the bounce plates 2a and 2b swing downward, As shown in FIGS. 3 and 4, the binding rings 3 a and 3 b are closed, and the raised portion 9 is pressed against the lower surface 11 of the frame body 1 and slides, and at the end of the rising operation of the operating lever 5 that is rising. In a state in which both end portions 8a and 8b of the inverted T-shaped tip portion 5c are pressed downward on both side edges of the opening 7 between both the bounce plates 2a and 2b, as shown in FIG. 9 engages with the protruding engagement portion 10 of the frame 1 from below, so that the closed binding rings 3a, 3 In addition to locking satisfactorily and securely, the operation lever 5 itself is also securely fixed and securely locked so as not to fall down by a small external force.

[0014] In this manner, when the binding rings 3a and 3b are closed and locked, and the two operating levers 5 that are standing up are pushed down while being strongly pressed as shown in Fig. 10, the raised portions 9 are raised. As the two spring plates 2a and 2b swing upward, the locks of the binding rings 3a and 3b and the lock of the operation lever 5 are released, and the binding rings 3a and 3b are moved from the engagement ring 10 to the position shown in FIG. Open as shown by the virtual line.

Therefore, there is no danger that the operating lever 5 will fall down unexpectedly and be unlocked, and the hand will be pinched. In addition, since the locking is possible, the binding rings 3a, 3b It is no longer necessary to increase the engaging force, and it can be used as a binder for documents that women and girls can easily handle.
