Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide closure suitable for use in binder notebooks and the like.

[0002]

2. Description of the Related Art As shown in FIGS. 5 and 6, a slide closing device which has been conventionally used in a binder notebook or the like has a first base 1 having a binding rod 11 and a binding rod 21.
A second base 2 which is attached to the upper surface of the first base 1 so as to be slidable in the width direction, and an operating rod 3 which is attached to the lower surface of the first base 1 so as to be slidable in the longitudinal direction. The operation converting mechanism 4 converts the sliding operation of the operating rod 3 in the longitudinal direction into the sliding operation of the second base 2 in the width direction, so that the second base 2 is moved with respect to the first base 1. The binding rods 11 and 21 are configured to be opened and closed by sliding in the width direction and contacting and separating. The motion conversion mechanism 4 is
The pin 41 and the pin 4 projecting from the upper surface of the operation rod 3 at three places
1. Long holes 42 extending in the longitudinal direction and penetrating at three positions of the first base 1 at positions corresponding to No. 1 and three positions on the lower surface of the second base 2 at positions corresponding to the pins 41. The guide groove 43 is formed, and the pin 41 penetrates the long hole 42 and enters the guide groove 43. The guide groove 43 is located at a position where the operating rod 3 is pushed the most and the second base 2 is in contact with the first base, and the operating rod 3 is pulled out most so that the second base 2 is the first base. It is provided obliquely so as to connect a straight line to the position of the pin 41 at the position farthest from the base body.
According to such a motion converting mechanism 4, as shown in FIG. 7, when the operating rod 3 is pushed into the first base 1 while the second base 2 is away from the first base 1, the pin 41 is extended. Hole 42
And moves inward in the guide groove 43 in the longitudinal direction. The guide groove 43 is set obliquely as shown in the drawing, and the contact point with the pin 41 moves inward and the guide groove 43 is formed.
Is pushed laterally, and the second base body 2 is slid toward the first base body 1 accordingly. When the operating rod 3 is pulled out with the second base 2 in contact with the first base 1,
The reverse process occurs and the second base 2 slides away from the first base 1.

In such a slide closure, the guide groove 43 is provided with an extending portion 431 and a convex portion 432 in order to secure the fixing more securely. The extending portion 431 is continuous in the longitudinal direction from the deep end of the oblique groove portion 433, and the convex portion 432 is provided in the guide groove 43 from the side surface of the boundary portion between the extending portion 431 and the oblique groove portion 433. The second substrate 2 is the first substrate 1
When the operating rod 3 is further pushed in after coming into contact with, the pin 41 passes over the convex portion 432 from the slant groove portion 433 and extends to the extending portion 431.
Enter. After that, the movement of the pin 41 in the longitudinal direction is blocked by the convex portion 432, so that the operating rod 3 is fixed.

[0004]

However, in such a slide closing tool, there is a problem that it is impossible to obtain a good operation feeling and a necessary and sufficient fixing strength.
That is, when the pin 41 rides over the protrusion 432 of the guide groove 43, the pin 41 or the protrusion 432 needs to be elastically deformed. However, since the pin 41 needs to push the guide groove 43, it is not possible to give a large elasticity, and the convex portion 432 or members around it cannot be pushed by the pin 41 effectively. Cannot be given. Therefore, the pin 41 and the convex portion 432 can perform only a small elastic deformation, and the convex portion 432 must be small in order to allow the pin 41 to ride over the convex portion 432.

For this reason, the click feeling of fixation caused by pushing the operation rod 3 becomes very small, and the operation feeling becomes poor. Further, the fixing itself is unavoidably loose, and there is a problem that it is difficult to function effectively as a closing tool especially when a large amount of paper is pinched and closed.

An object of the present invention is to effectively solve such a problem.

[0007]

In order to achieve the above object, the present invention employs the following configuration. That is, the slide closure according to the present invention includes a first base body having a binding rod and a second base body having the binding rod and slidably attached to the first base body in the width direction,
An operation rod provided so as to be slidable in the longitudinal direction on the first base, and an operation for converting a sliding motion of the operation rod in the longitudinal direction into a sliding motion in the width direction of the second base. A slide closing device configured to open and close the binding rod by bringing the second base body into contact with and away from the first base body by a conversion mechanism, wherein a first operation rod is provided between the operation rod and the first base body. The operating rod is provided with a concave-convex engaging portion which engages at a position pushed into the base body, and the operating rod is provided with a long hole extending in the longitudinal direction inside the concave-convex engaging portion, the outer periphery being continuous with the same member. An elastically deforming portion is provided on the outer peripheral portion of the elongated hole so as to elastically deform when the concave-convex engaging portion is engaged.

As one mode of implementation of the concave and convex engaging portion,
An example is a projection formed on the first base and a recess formed on the side surface of the operating rod.

As one embodiment of the elastically deformable portion,
An example thereof is one including a groove portion extending in the longitudinal direction on the outer peripheral portion of the long hole of the operating rod.

[0010]

With the slide closing device having such a structure, after the second base is brought into contact with the first base to close the binding rod, the operating rod is further pushed to engage the concave-convex engaging portion,
The operating rod is fixed to the first base body. The click feeling when the operating rod is fixed by the engagement of the concave-convex engaging portion is great, and the operating rod is very surely fixed to the first base by the concave-convex engaging portion. It is possible to dramatically improve the operation feeling and fixing strength of the slide closing tool. Further, the elastic deformation necessary for engaging the concave-convex engaging portion is performed by the deformation of the outer periphery of the long hole formed inside the concave-convex engaging portion of the operating rod, but the outer periphery of the long hole is continuously formed by the same member. Since the deformation is carried out by the entire outer peripheral member, the local burden is small. Therefore, the settling of the member can be reduced, and the concave-convex engaging portion can be made highly durable.

Further, when the concave-convex engaging portion is constituted by the convex portion protruding from the first base and the concave portion formed on the side surface of the operating rod, there is no convex portion on the operating rod side, and therefore the first convex portion is formed. The concave-convex engaging portion does not interfere with the insertion / removal of the base body. Further, such a concave-convex engaging portion can be provided in the conventional slide closing device by only slightly changing the shape of the member, and the increase in the manufacturing process and the manufacturing cost can be minimized.

Further, when an elastically deforming portion having a groove portion extending in the longitudinal direction is provided on the outer peripheral portion of the elongated hole of the operating rod, the deformation necessary for engagement of the concave and convex engaging portion is applied to the peripheral portion of the groove portion. The deformation can be performed, and the concave-convex engaging portion can be made larger and can be securely engaged.
