Description

[Detailed Description of the Invention] [Industrial field of application] The present invention uses a flexible synthetic resin thin plate in a circular shape.
The present invention relates to a cell ring binding device for integrally binding a large number of circular winding strips on a single curved strip at required intervals and hooking the winding strips on a loose-leaf square hole of the sheet to bind the sheet.

[Prior Art] Since the conventional cell ring binding device cannot adjust the tension position of the tension plate that spreads out the circular winding piece of the cell ring, if the diameter of the circular winding piece is small, the tension plate is not used. It was inconvenient to stop on the way.

[Problems to be Solved by the Invention] An object of the present invention is to increase the practical value of a cell ring binder by allowing the tension plate to be stopped at any position.

[Means for Solving the Problems] Means of the present invention are as follows.

On one side of an elongated curved strip made of a flexible synthetic resin thin plate,
In a binding device that winds the circular winding pieces of a cell ring in which circular winding pieces are integrally arranged in a row at a constant interval, around a small hole of a loose-leaf paper bundle, a cell is provided at the upper end of the upper plate of the binding body. While forming a guide deep groove that slidably inserts the comb-like plate that supports the ring, place a pulling plate in which hook pieces for hooking the circular winding pieces are arranged on the upper surface plate, and on the lower surface of the pulling plate. Insert a plurality of protruding pins into the inclined slot formed in the operating plate through the vertically elongated hole in the upper plate, and attach a slender operating plate to the right side of the lower surface of the upper plate of the body so that it can slide left and right. The spring acts on the plate in one direction, and the bent portion of the operation lever is pivotally attached by the operation lever fulcrum pin projecting to the lower surface of the upper plate to engage the tip 2 or the portion with the downward pin of the operation plate. The tip of the L-shaped fixed lever is pivotally attached to the fixed lever fulcrum pin fixed to the left side of the lower surface of the Attached to the L-shaped fixed lever are two contactors that stop by sandwiching the upper and lower sides of the operating plate that slides against the spring of the operating plate, and both contactors act in a direction to stop by sandwiching the operating plate. Cell ring binding device in which the L-shaped fixed lever is pressed.

EXAMPLES numeral 1 indicates the device body, to form a comb-like plate 2 slidably difference writing guided deep grooves 3 for supporting the cell ring S to the upper end of the upper plate 1 _1, also the top plate 1 ₁ Place the tension plate 5 projecting from the integrally many Kagihen 4, the circular Makikomihen b to exist a predetermined distance on one side of the elongated curved strip a molded flexible synthetic resin sheet, The curved strip a of the cell ring S in which b is integrally arranged is applied to the outer side of the comb tooth-shaped plate 2 and the circular winding piece b is hooked on the hook piece 4 from the gap of the comb tooth-shaped plate 2.

Two pins 6,6 which protrude to the rear surface of the tension plate 5 projects through the elongated hole 7, 7 bored in the top plate 1 _1, the upper surface plate 1
_The pins 6 are inserted into the inclined groove holes 9 of the operating plate 8 which are overlapped on the back surface of ₁ . Further, the coil spring 17 is hooked on the protrusion 15 of the operating plate 8 and the guide pin 16 on the rear surface of the upper plate. Reference numeral 13 denotes an operation lever, and the operation lever fulcrum pin 12 allows the top plate 1 ₁
Pivoted in, engage the bifurcated part 13 ₁ of the operation lever 13 to the pin 14 of the actuating plate 8, when the operation lever 13 is operated around the fulcrum pin 12, the operating plate 8 through a pin 14 to the left and right Slide. Thus, moving along the inclined slot 7 and pulling the actuating plate 8 toward the front, the circular winding piece b of the cell ring hooked on the hook piece 4 is expanded, and in that state a large number of stacked paper sheets are bent. If it is dropped onto a and the tension plate 5 is returned to its original position, the circular winding piece b penetrates the loose leaf hole of the paper sheet and is attached. 1
Reference numerals 9 and 20 denote guide ridges of the operating plate 8 that guide the operating plate 8 when the operating plate 8 is slid.

When the operating lever 13 is stationary, the operating plate 8 also stops against the coil spring 17 so as to stop.
There is. L-shaped fixing lever 21 is pivotally connected to the fixed lever fulcrum pin 10 fixed to the lower surface of the upper plate 1 _1, comprising a hydraulic plate 8 contacts 22 1 of 2箇sandwiching in contact with the upper and lower _edges, 22 _2,
One end of the wire spring 11 wound around the fixed lever fulcrum pin 10 is hooked on the body 1 and the other end is hooked on the L-shaped fixed lever 21.
The elastic force of ₁ causes the contacts 22 ₁ and 22 ₂ to press the operating plate 8 and stop. Then, attach the L-shaped fixed lever 21 to the wire spring 11
1 against the fixed lever fulcrum pin 10 against the arrow
Moving in the direction, the contact 22 _1, 22 ₂ are slightly away from the actuating plate 8, when the operation lever 13 in this state about the support pins 12, the operating plate 8 against the coil spring 17 is slidingly When the L-shaped lever 21 is moved and released at an arbitrary sliding position, the actuating plate 8 is stopped against the coil spring 17 by both contacts 22 ₁ and 22 ₂ . When the L-shaped fixed lever 21 is operated again, the action plate 8 and the tension plate 5 are returned to their initial positions by the action of the coil spring 17.

[Operation] When engaging the cell ring comb tooth-shaped plate 2, hooking the circular winding pieces b, b on the hook piece 4 of the tension plate 5 and operating the operating lever 13, the tension plate 5 pulls the hook piece 4. If the operation lever 13 is moved forward as it is and the operation lever 13 is stopped at an arbitrary position, the position is maintained as it is. When the cell ring is aligned with the square hole of the loose leaf paper and the L-shaped fixing lever 21 is operated, the operating plate 8 and the tension plate 5 are returned to their original positions, and the circular winding piece b of the cell ring is locked in the square hole. .

[Effect] According to the present invention, since the tension plate can be stopped at a desired position, it can be used according to the size of the circular winding piece of the cell ring. Especially, the structure of the present invention has a very simple structure. The operation is always smooth and there is no risk of failure.
