TECHNICAL FIELD OF THE INVENTION
The present invention relates to a base fixing structure of a binding device that can easily perform an operation of fixing a base of the binding device to a spine or the like as a surface to be fixed.
[0002]
[Prior art]
Conventionally, a file including a binding tool on the inner surface side of a file main body formed of a spine or the like is commercially available. For example, as a binding device used for this type of file, a base fixed to a fixed surface of a file body, a pair of binding plates arranged on both left and right sides of the base, and a binding rod extending between these binding plates. And the like.
[0003]
In addition, since such a file has a binding device made of a material different from that of the file body, it is possible to easily separate and discard the file due to a recent garbage problem and the like, and it still has a value to be used as a part. In order to facilitate the reuse of the parts, a base fixing structure is adopted in which a binding device having a base fixed to a fixed surface such as a spine is detachably fixed to the fixed surface. There are many things. Specifically, a first fixing element including an outer portion that can be positioned on the outer surface side of the fixed member, and a second fixing element that is detachable by being rotationally displaced with respect to the first fixing element.

JP-A-2000-118181 (page 3, paragraph number 0015, etc.)
[0005]
[Problems to be solved by the invention]
However, the base fixing tool rotates the second fixing element, and fixes the both by engaging the free end side of the second rotating element with the engaging claw of the first rotating element. Since the function for keeping the base and the file main body tight in the fixed state is provided on the free end side, it has been difficult to attach / detach the second fixing element.
[0006]
That is, in order to tighten the base and the file main body in a fixed state, for example, a peripheral wall having a length dimension sufficient to press the base against the file main body is provided on the free end side of the second fixing element, and the base is pressed. In addition, a structure is adopted in which the free end is firmly engaged with the first fixing element while the file main body is drawn, thereby tightening the two. Therefore, in addition to employing a structure in which the base is fastened to the file main body at a position distant from the rotation fulcrum, the second fixed element can not have a margin for the engagement dimension on the free end side serving as the operating end. The force required for the engagement operation and the disengagement operation was large.
[0007]
[Means for Solving the Problems]
In view of the above, the present invention has been made in view of the above problems, and has a base fixing structure that removably fixes a binding device having a base fixed to a fixed surface such as a spine on the fixed surface. A first fixing element including an outer portion that can be positioned on the outer surface side of the fixed surface; and a second fixing element whose free end side is detachable by being rotationally displaced with respect to the first fixing element. A base fixing tool having a fixing element and a tightening means for tightening the base to a surface to be fixed in accordance with the rotational displacement of the second fixing element, wherein the tightening means is a rotation fulcrum of the second fixing element; The base and the fixed surface when the second fixing element is rotationally displaced with respect to the first fixing element in a state where the outer portion is attached to the outer surface of the fixed surface. It is characterized in that it is sandwiched between each fixed element in the state That.
[0008]
Thus, the tightening means is provided on the rotation fulcrum side so that the force required for fixing and releasing the rotation element can be reduced. In other words, by adopting such a configuration, it is only necessary to provide the function of holding the second fixing element at a predetermined position on the free end side serving as the operating end, so that the attaching / detaching operation can be easily performed. .
[0009]
As a specific configuration, the base fixture has a first engagement portion formed of a rotation shaft serving as a rotation fulcrum of the second fixing element and a rotation bearing for receiving the rotation shaft; A second engaging portion that is provided on a free end side of the fixing element and engages each fixing element when the second fixing element is rotationally displaced with respect to the first fixing element. It is possible.
[0010]
With such a configuration, it is also possible to give play to the engagement dimension setting on the free end side.
[0011]
In addition, by providing the free end of the second fixing element closer to the edge of the base than the rotation fulcrum of the second fixing element, the operator can more easily operate the operation end and more easily apply force. Further, for example, even with a binding tool having a binding rod or the like extending between the binding plates, a free end serving as an operation end can be easily arranged at a position avoiding the binding rod.
[0012]
Further, the tightening means includes a pressing portion that presses the base in a direction of tightening the base against the surface to be fixed with the rotational displacement of the second fixing element, and the pressing portion serves as a scaffold for the first fixing device. It is also possible to adopt a configuration in which the fixing element is drawn toward the second fixing element, and the second fixing element can be easily attached and detached with a small force.
[0013]
Further, in order to configure a simple structure, it is preferable to provide a rotation shaft on the base fixture and provide the pressing portion on the rotation shaft.
[0014]
In addition, as a specific configuration, it is conceivable that the rotating shaft has a crank shape.
[0015]

[0039]
Next, a case where an impact force for releasing the engagement between the base element 31 and the rotary element 32 due to an unexpected operation such as dropping the file F is applied will be described. For example, when the file F is dropped with the left and right edges of the file body 1 hitting the floor, a force is applied in a direction in which the file body 1 separates from the base 21, that is, a downward direction in FIG. At this time, the contact surface 324d of the rotating shaft 324 bends to the opposite contact surface side, and moves in the direction in which the rotating shaft 324 is pushed into the rotating bearing 313 as shown in FIG. The impact force applied to the engaging portion 5 is absorbed to maintain the engaged state.
[0040]

Further, even with the binding tool 2 provided with the binding rods 25 extending between the binding plates 24, the free end serving as the operation end can be easily arranged at a position avoiding the binding rods 25.
[0043]
Further, the tightening means 4 includes a pressing portion 324c for pressing the base 21 in a direction of tightening the base 21 against the surface to be fixed in accordance with the rotational displacement of the rotary element 32. The rotary bearings 313 provided on the base element 31 located on both sides of the portion 324c are pulled toward the rotary element 32, and the rotary element 32 can be easily detached with a small force.

However, the rotating shaft 324 has a shape in which the size in the direction of pressing the base 21 is increased with the rotational displacement of the rotating element 32, for example, a rotation having an elliptical side cross section. A shaft 324 is also conceivable. Further, in the present embodiment, the rotating shaft 324 is provided on the rotating element 32, but may be provided on the base element 31. Further, it is a matter of course that a part of the rotating shaft 324 may be formed of a flexible member or the like that is easily bent to form a bent part, and the bent part may absorb an impact. Further, in the present embodiment, the pressing portion 324b is provided on the rotating shaft 324. It is also conceivable to press the button.
