Description

  The present invention relates to a binding tool and a file capable of binding paper sheets.

  Conventionally, various files for binding paper sheets and binding tools attached to the files have been proposed. Among them, with regard to the binding tool that presses the paper sheets by engaging with the flexible binding feet attached to the cover body, the paper sheets can be bound and added by a simple operation. In addition, various ideas have been made. (For example, refer to Patent Document 1).

  In the above-described patent document, a base including a plurality of binding foot insertion portions for inserting a plurality of binding feet, and a base that is operatively attached to the base and binds one binding foot. A first pressing portion that can be pressed from above the foot insertion portion, and a second pressing portion that is operatively attached to the base and that can press the other binding foot from above the binding foot insertion portion. From the binding position in which these holding portions are positioned along the base, the binding between the binding foot and the binding tool is released by simply picking up any binding member with, for example, a finger, and binding or removal of paper sheets is performed. Is easy to do. Then, when the picked-up presser part is pressed toward the base, the binding tool again takes a binding posture that engages with the binding foot. Such binding tools have been widely accepted in offices.

  Here, paying attention to the movement of the finger when handling the binding tool in this way, the operation of picking up the pressing portion as described above is pulled upward to release the engagement between the binding foot and the binding tool. Power is required. In other words, when such a picking operation is performed, the user is inevitably required to have a gripping force or gripping force with a finger above a certain level without being aware of it. Sufficient awareness and normal / healthy finger movement are required.

  On the other hand, when considering a binding tool that can be operated with a single finger that is easier than picking, such as a simpler operation than a picking action, that is, a simple pushing action or a part sliding action, such a simple action. Also, it is required that the binding tool accurately and reliably performs a predetermined posture change.

On the upper side of the external fitting protrusion 423, a release facilitating surface 424 is formed, which gradually decreases in the upward direction and makes it easy to release the engagement. The outer fitting protrusion 423 engages with the engagement step portion 233 from the outside so as to hold the binding posture holding portion Z that can stably maintain the binding posture (P) together with the engagement step portion 233. It is composed.

  The central hinge 43 is a resin hinge that connects the sliding plate portion 42 and the lower connection plate portion 44 so as to be bendable. In the present embodiment, in the vicinity of the central hinge, the sliding plate portion 42 and the lower connecting portion 44 are formed by retracting the resin in the thickness direction on both sides, so that any guide protrusions 27a and 27b can be formed in the binding posture (P). It is designed not to interfere.

  The lower connecting plate portion 44 is fixed to the upper connecting plate portion 36 by engaging the tip portion 441 with the end claw 361 and the step portion 442 with the side claw 362, and operates with the binding operation plate 35 as a link element. It can be made. The lower connection plate portion 44 forms a recess 444 in which the resin at both ends is recessed in a trapezoidal shape at a position closer to the first pressing portion, that is, a position closer to the first pressing portion.

The pivot end 462 is the same. The floating prevention link 46 prevents the inconvenience that the second pressing portion 41 is unnecessarily separated upward from the base 2 in the retracted posture (Q) together with the holding portion 422 described above.

  In the binding tool 1 according to this embodiment, the first pressing plate 3 and the second pressing plate 4 constitute an interlocking mechanism X including a link portion of the present invention. That is, the interlocking mechanism X according to the present embodiment is a substantially four-sided structure in which the binding operation plate 35 and the lower connection plate portion 44, the binding operation plate 35, the positioning link 45, and the anti-floating link 46 that operate integrally are used as link elements. It consists of a link part that is a link.

  And this interlocking | linkage mechanism X makes the operation | movement of the 1st holding | suppressing part 32 and the operation | movement of the 2nd holding | suppressing part 41 interlock | cooperate by operation | movement of this each link element, and is from a binding attitude | position (P) to a retracted attitude | position (Q). The mutual operations can be linked with each other. Then, under the operation of the interlocking mechanism X, the operation unit 31 can be operated from the binding posture (P) to the retracted posture (Q) only by a pressing operation along the longitudinal direction of the base 2. Yes.

  Therefore, the binding tool 1 according to the present embodiment, in addition to the above-described interlocking mechanism X, converts the pressing operation in a predetermined direction into an operation in a direction in which the posture is changed from the binding posture (P) to the retracted posture (Q). Y is provided, and this motion conversion mechanism Y can achieve both a stable binding posture (P) and a posture change to a smooth retracted posture (Q) together with the binding posture holding section Z described below. Hereinafter, the configuration of the motion conversion mechanism Y and the binding posture holding unit Z will be described.

  In the present embodiment, the motion conversion mechanism Y is provided on both sides of the second binding plate 4 and the guide protrusions 27a and 27b formed in pairs on the both ends in the width direction provided on the base 2 as described above. This is a configuration having a recess 444. Specifically, the motion conversion mechanism Y includes guide surfaces 271a and 271b that are upward inclined surfaces provided on the guide protrusions 27a and 27b, and a contact surface 445 formed in the recess 444.

The binding posture holding portion Z is provided on the engagement step portion 233 formed on the rail portion 23 of the base 2 and the second binding plate 4 constituting the interlocking mechanism X and is externally fitted to the engagement step portion 233. The outer fitting protrusion 423 is obtained.

  Hereinafter, the operation of the binding tool 1 from the binding posture (P) to the retracted posture (Q) will be described by first focusing on the interlocking mechanism X. When the operation unit 31 is pressed toward the positioning units 26a and 26b in the longitudinal direction of the base 2 from the binding posture (P) shown in FIGS. 1, 3, 6 and 13, the operation unit 31 and the first pressing unit With the sliding motion along the rail portion 23 of 32, the positioning link 45, which has been maintained in a posture parallel to the base 2, rotates around the inner hole 261a and stands up (FIG. 14). Along with this standing operation, the binding operation plate 35 rotates while raising the binding operation end 351 as the operation side hinge 34 is deformed. On the other hand, as the binding operation plate 35 rotates, the central hinge 43 is deformed, and the sliding plate portion 42 rotates upward. At this time, the second pressing portion 41 positioned at one end of the sliding plate portion 42 is retracted from the binding foot insertion portion 21. Since the sliding plate portion 42 is connected to the outer hole 262a via the floating prevention link 46, the second pressing portion 41 rotates while sliding in the space in the concave groove 232 toward the positioning portion 26a. Will be performed. In this way, the binding tool 1 assumes the retracted posture (Q) shown in FIGS. 2, 4, 7, and 15.
