とを目的としたものである。Problems to be Solved by the Invention However, according to the binding tool of the conventional structure, the weight of, for example, the bound paper mount in the attached state is applied to the end member 11 via the binding member 10 and the locking stepped portion 114b of the locking piece 115 is applied. When an inward external force is applied to the locking projections 116, 116, the locking protrusions 116, 116 tilt inward using their bases as fulcrums, and the direction of this inclination is such that the binding rod 9a is aligned with the locking step 11.
4b, there is a risk that the engagement between the binding rod 9a at the end position and the locking piece 115 will come off, and when the end member 110 is attached to the end of the back member 7 , intervenes by pressing the oblique edges of the locking pieces 115, 115 while slidingly contacting the binding rod 9a at the end position.
Since it is necessary to tilt the entire part 116 inward, there is a disadvantage that sliding friction resistance is strong and interventional operations are difficult. Therefore, the present application provides a binding tool that is configured so that when an external force is applied to the end member in the direction of removal, the engagement with the binding rod at the end position is strengthened, and the end member is configured to be easily attached with a light force. It is intended to provide.

場合にその浮き上がりを防止できる。Function: When the binding member is engaged with the spine member by inserting the connecting rod of the binding member into one of the locking grooves of the back member and the tip of the binding rod into the other locking groove, the binding member is engaged with the back member. On the other hand, insert the insertion protrusion of the end member into the insertion groove. Then,
The locking piece of the locking protrusion is pressed inward while sliding in contact with the inside of the binding rod located at the longitudinal end of the binding member, and if the end member is continued to be inserted in this state, the locking piece will When it passes through the inner surface of the binding rod at the end position, it is restored by the repulsive force, and the notch portion is engaged with the binding rod, and the pair of left and right abutting protrusions intervenes on the inner surface of the left and right locking grooves, respectively. , and the end plate of the end member comes into contact with the end surface of the back member, so that the binding member is held on the back member. In this state, for example, if the weight of the bound paper sheets acts as an external force on the end member via the binding member, an external force in the same direction is also applied to the notch. Then, since the locking piece extends freely from the tip, it is tilted outward by the external force, and the direction of the inclination is the direction in which the notch engages with the binding rod, so the locking piece is There is no danger of it slipping out of the rod. Further, in the above, when the end member is removed, the locking piece is pressed inward in the same manner as in the prior art, the notch portion is released from the binding rod, and the end member is pulled out in this state. In addition, when a two-part slit is provided, the bending force of the locking piece of the end member increases, making it easier to engage and release the end member. Engagement and disengagement operations become easier. Further, the insertion groove is open along the center of the upper surface, and integrally forms the insertion protrusion and the locking protrusion of the end member, and the left and right side surfaces between the insertion protrusion and the locking protrusion. When a locking groove is provided to be inserted into the central opening of the insertion hole, the end member is inserted into the center opening of the upper surface of the insertion groove of the back member, and the end member is inserted into the back member. Attach to. Further, when the outer half of the upper surface of the locking piece is sloped downward, it is possible to prevent the stacked paper from lifting up when the paper is opened.

止片１６が綴杆９より外れる惧れはない。 Then, the connecting rod 8 of the binding member 10 is inserted into one of the locking grooves 6a of the back member 7, and the tips of the binding rods 9, 9, etc. are respectively inserted into the other locking groove 6a, and the binding member In order to hold the binding member 10 with respect to the back member 7 in the state in which the binding member 10 is engaged, the left and right end surfaces of the end plate 13 are held as in the conventional case, and the locking grooves 19 and 10 of the end member 12 are
19 to the opposing first ribs 2 forming the insertion groove 5,
The insertion protrusion 14 is inserted into the insertion groove 5 by being engaged with the central opening formed by the inner edge of the insertion groove 5. Then, the oblique edge 16a of the locking piece 16 is pressed inward while slidingly contacting the inside of the binding rod 9a located at the longitudinal end of the binding member 10, and the end members 12, 12 are continued to be inserted in this state. The locking piece 16 is attached to the binding rod 9 at the end position.
When it passes through the inner surface of a, it is restored by the repulsive force,
The notch 15 engages with the binding rod 9a, and the pair of left and right abutting protrusions 20 intervenes in the inner surfaces of the left and right engagement grooves 6a, 6b, respectively, and the end plates 13 of the end members 12, 12 are held against the back. A binding member 10 is held by the spine member 7 in contact with the end surface of the member 7. In this state, for example, if the weight of the bound sheets acts on the end member 10 as an external force in the direction of the arrow in FIG. Then, the locking piece 16 tilts outward with the closed end a of the spacer 17 as a fulcrum, and the direction of the tilt is the direction in which the notch 15 engages with the binding rod 9a, so the locking piece 16 There is no danger that it will fall further than 9.
