Description

[Detailed description of the invention] The present invention is a binding tool, more specifically, a pair of stop plates equipped with a stop ring are placed between the locking portions of an elongated base body having a pair of locking portions. The present invention relates to a binding device which is reversibly attached, so that the retaining ring can be opened and closed, and is elastically maintained in a closed position and an open position.

Generally, with this type of binding tool, when opening the retaining ring from a closed state or closing it from an open state, it is necessary to hold each tip of the retaining ring and apply force in the opening or closing direction. Since this is done by elastically inverting the stop plate using the abutting part of the stop plate as a fulcrum, when a large amount of paper is being stapled into the stop ring, there is no possibility that an external object may come into contact with the stop ring. When an external force is applied to the retaining ring due to a slip or a dropping of the binding tool, the tip of the retaining ring is inadvertently opened, causing a problem in which the piece of paper comes off from the retaining ring.

The present invention has been devised in view of the above problems, and its purpose is to provide a sliding body that controls the reversal of the stop plate, and to prevent the stop plate from reversing and release the inhibition by the movement of the sliding body. Even if an external force is applied to the retaining ring when the retaining ring is closed, the retaining ring can be reliably prevented from opening.

Therefore, the configuration of the present invention provides a sliding body having a control piece for controlling the reversal of the stop plate, and receives the control piece between the abutting edges of the stop plate to enable the reversal of the stop plate. A first gap and a second gap for preventing the stop plate from reversing are formed, and the sliding body is slidable along the length direction of the base, and the second gap of the control piece The locking ring is maintained in the closed position by intervening between the locking ring and the locking ring.

Embodiments of the binding device of the present invention will be described below based on the drawings.

The binding device according to the embodiment of the present invention shown in the figure consists of an elongated base 1 having a pair of locking parts 11, 11, and a pair of stop plates 2, 3 equipped with stop rings 4, 5. The stop plates 2 and 3 are attached between the locking parts 11 and 11 of the base body 1 so as to be butted against each other and are reversible, so that the stop rings 4 and 5 can be opened and closed. and the open position.

The base body 1 is mainly made of a thin metal plate, and is formed into a substantially C-shaped cross section, with the locking parts 11 and 11 formed on both sides in the width direction, and the retaining ring 4 on the upper surface thereof. , 5 are provided, and through holes 13, 13 are provided at both ends in the length direction of the base 1.
The base body 1 is fixed to the upper surface of the base plate 7 by the pins 0 and 10.

Further, the stop plates 2 and 3 are also mainly made of metal plates, and are formed so that the total width dimension of these stop plates 2 and 3 is larger than the interval between the locking parts 11 and 11, and each stop plate 2 , 3 has a protrusion 2 that rides on the upper surface of the adjacent stop plate 2 or 3.
1 and 31 are provided in a protruding manner to maintain the abutting state of both stop plates 2 and 3, and these stop plates 2 and 3 also have a substantially semicircular arc-shaped stop ring 4 into which a piece of paper 8 is inserted. , 5 are each fixed.

The present invention provides a binding device having such a structure, in which a sliding body 6 having a control piece 60 for controlling the reversal of the stop plates 2 and 3 is provided, and the control piece 60 is provided between the abutting edges of the stop plates 2 and 3. and forms a first gap A that prevents the stop plates 2 and 3 from reversing and a second gap a that prevents the stop plates 2 and 3 from reversing. The second control piece 60 is slidable along the length direction of the second control piece 60 .
This is done to maintain the closed position of the retaining rings 4 and 5 by intervening in the gap a.

The sliding body 6 has a U-shaped cross section as shown in FIG. 4, and one end of one side wall 61 is bent inward to form a hook-shaped control piece 60, and the other side wall 62 extends outward. The control piece 63 is provided in a protruding manner, and when the control piece 60 is positioned in the first gap A, the side wall 61 is inserted into the first and second gaps A, a, and the other side wall The inner surface of 62 is aligned with the outer surface of the locking part 11 of the base 1, and in this state, the slider 5 is slidable between the base 1 and the base plate 7 along the length direction of the base 1. Thus, the control piece 60 can selectively intervene in the second interval a.

The binding tool of the present invention is constructed as described above, and when binding paper pieces 8 to the binding tool, first, the sliding member 6
is moved from the solid line position to the imaginary line position shown in FIG. Release the inversion prevention of bodies 2 and 3.

Thereafter, by holding the tips of the retaining rings 4 and 5 and applying force in the direction of opening these retaining rings 4 and 5, the retaining plates 2 and 3 are reversed using their abutting portions as fulcrums, and the retaining rings 4 and 5 are inverted. , 5 are opened and the open state is maintained elastically,
The binding holes formed in the paper strip 8 are inserted into the retaining ring 4 or 5.

Thereafter, a force is applied to the tips of the retaining rings 4 and 5 in the closing direction, and the retaining plates 2 and 3 are reversed using their abutting portions as fulcrums to elastically close the retaining rings 4 and 5, and further, The sliding body 6 is moved from the imaginary line position shown in FIG. 2 to the solid line position. This movement causes the control piece 60 of the sliding body 6 to move between the first
Then, the hook-shaped control piece 60 is fitted into the edge of the stop plate 3 forming the second gap a, and the stop plates 2 and 3 are reversed. can be definitely prevented.

Therefore, even if an external force is accidentally applied to the retaining rings 4, 5 during binding, the retaining rings 4, 5 will not open accidentally.

In the previously described embodiment, the abutting edges of both stop plates 2 and 3 were cut out to form the first and second gaps A, a, but only one of these stop plates 2 and 3 was cut out. Alternatively, the first and second gaps A and a may be formed.

In addition, the control piece 60 is formed by bending one end of the side wall 61 to form a hook shape as described above.
1 itself may be used as the control piece 60.

In this case, the length of the side wall 61 is made shorter than the embodiment shown in the drawings, and the sliding body 6 is connected to the stop plates 2 and 3.
When the side wall (control piece) 60 is located in the reversible position, the side wall (control piece) 60 is located within the first interval A, and when the sliding body 6 is slid toward the second interval A, the side wall (control piece) is located within the first interval A. The control piece 60 is positioned in the second gap a, and the thickness of the second gap a is about the same as the thickness of the side wall 61, so that the side wall (control piece) is located in the second gap a.
When located at the gap a, it is configured to press into engagement with the end surfaces of the stop plates 2 and 3 forming the second gap a.

As described above, the present invention provides a sliding body having a control piece that controls the reversal of the stop plate, and a sliding body that receives the control piece between the abutting edges of the stop plate and enables the stop plate to be reversed. A first space and a second space for preventing the stop plate from reversing are formed, and the sliding body is slidable along the length direction of the base, and the second space of the control piece is Since the stop ring is maintained in the closed position by intervention in the stop ring, the movement of the sliding member can prevent the stop member from reversing and release the inhibition;
When the retaining ring is closed, even if an external force is applied to the retaining ring, the retaining ring can be reliably prevented from opening, and the piece of paper can be reliably prevented from being accidentally removed from the retaining ring. It is.
