JPH07214963A - Plane rotary type horizontal u-shape leaf spring clip - Google Patents

Abstract

PURPOSE:To improve the page turning-over operability of a conventional double clip and to facilitate the operation of a backside operation lever from an opening operation state to a housing state. CONSTITUTION:A paper gripping horizontal U-shape leaf spring 2, the operation lever 1 operating the spring 2 and the rotary guide member of the operation lever 1 making the rotary plane of the operation lever almost flush with the plane of paper to be bound are provided. A positioning member capable of being stopped at an appropriate position is provided so as to prevent such a phenomenon that the operation lever 1 excessively rotates toward the upper surface of paper in a housing state to obstruct the turning-over of paper.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip used for binding paper such as notepaper.

[0002]

2. Description of the Related Art Conventionally, there is a clip using a U-shaped leaf spring called a double clip. This double clip stands up in the vertical direction with respect to the flat surface of the paper to be bound.
It had an operating lever that rotated 80 degrees. In other words, it was a type that rotates the operating state of the operating lever and the stored state 180 degrees perpendicular to the plane of the paper.

[0003]

In the conventional double clip, when the sheets are bound and stored, the operation lever closes the upper surface of the sheets. If you try to turn the page of the paper, this operation lever will interfere, so after turning the operation lever once to position it on the opposite side, you will turn the page of the paper,
There was a problem that the operation was complicated and difficult to use when checking the description content of the paper.

[0004]

[Means for Solving the Problems] The problem is achieved by setting the movement locus and the stoppable position of the operating lever for creating the operating state and the stored state of the operating lever as follows. A rotation guide member that rotates on the same or substantially the same plane as the upper surface, which is the portion of the U-shaped leaf spring that is located on the plane formed by the sheets to be bound, is provided, and the U-shaped leaf spring is attached to this rotation guide member. A positioning member that can stop the operation lever is provided at the position where the operation lever to be opened is rotated and the operation lever is stored, and the operation lever moves to the upper part of the bound paper more than the U-shaped leaf spring part that sandwiches the paper. By creating a state where it stops at a position where it does not enter, the means is to position the operation lever at a position that does not interfere with page turning of the bound paper.

[0005]

[Operation] Since the operation lever is located at a position that does not obstruct the page turning of the bound paper, the operation lever does not obstruct the page turning of the bound paper when the operation lever is stored. ．

[Figure 3]

FIG. 4 shows an embodiment of the present invention.

FIG. 1 is a side view showing an embodiment of the present invention in a state where an operation lever is in a state of pinching a sheet. Operation lever 1 is attached to U-shaped leaf spring 2.

FIG. 2 is a front view of the same state, in which one operation lever is 2
The rotation center of the tip of 2a, which is a part of the U-shaped leaf spring, and the cut-and-raise of the operation lever position holding of 3 are sandwiched by a rod-shaped spring effect. The length that the operation lever 1 is sandwiched is the length when the operation lever L1 is operated.
Since the length of the operation lever of 3 is shorter than the length of the operation lever that is being rotated, the operation lever of 1 is shown by the force of the spring to be inserted

[Fig. 2] The tip winding opening of 2b is opened so that the operation lever 1 can be mounted and rotated, and the tip winding rotation center of 2a and the tip winding both ends of 2c are not completely opened. When sandwiching the paper, in this state

[Fig. 1] Operate in the direction of the arrow of Fig. 1 to pull and spread the U-shaped plate spring 2 and sandwich the paper between the U-shaped molds to press and fix it by the leaf spring effect. When shifting to the stored state, use the 1 operation lever

2) Rotate in the direction of the arrow. as a result

[Figure 3]

[Fig. 4] Localize to the state of. In order to automatically position the operating lever of 1 to each position, the length of the operating lever of L1 when operating the operating lever and the length of the operating lever of 2 when storing the operating lever are L3.
It is necessary that the length is smaller than the length that the operating lever is clamped during rotation. By reversing the above operation, it is possible to return from the stored state to the paper sandwiched state.

FIG. 8 shows another embodiment of the present invention.

FIG. 5 is a side view showing another embodiment of the present invention when the operation lever is in the retracted state and the sheet is sandwiched.

[Figure 6]

FIG. 5 shows a front view of FIG.

6 has a tip portion which forms a substantially circular shape, and the circular portion is guided to the rotation center of the tip winding of 2a and rotates from the state of sandwiching the paper in the state of three-dot chain line to the storage state of the solid line. 2d tip wrap around both ends

[Fig. 7] The upper part is opened as shown in Fig. 7, and the position of the operation lever 1 is localized. At the time of rotation, the position can be moved by elastic deformation of the leaf spring state of the 2d tip-engaged end opening.

[Figure 1]

2 is basically different from the embodiment of the present invention in that there is no operation lever position holding cut-and-raise of 3 and that the stored state is localized by the 2d tip-entrance end opening.

FIG. 9 is a front view showing another embodiment of the present invention when the operation lever is in the stored state and the sheet is sandwiched.
The solid line of the operation lever of No. 1 shows the state when it is stored, and the three-dot chain line shows the state when the paper is sandwiched.

[Figure 9]

[Figure 1]

FIG. 2 is different from the embodiment of the present invention in that the width of the center of rotation of the leading end of 2a is small, and therefore the winding diameter is also small.
