DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention According to the binding device having the conventional configuration, for example, the weight of the mount that is bound in the mounted state is applied to the end member (11) through the binding member (10) and the locking piece (115). When an inward external force is applied to the locking step (114) b of the locking projections (116) and (116), the locking projections (116) and (116) are tilted inward with their roots as fulcrums, and the direction of this tilt is the binding ring ( Since 9) a is in the direction of disengagement from the locking step (114) b, there is a risk that the engagement between the binding rod (9) a at the end position and the locking piece (115) may be unnecessarily released. , End members (110)
In the case of attaching the tongue to the end of the back member (7), the slanted edges of the locking pieces (115) and (115) are slidably pressed against the binding rod (9) a at the end to intervene. However, since the locking projections (116) and (116) are required to be tilted inward when they are pushed in, the sliding friction resistance is strong, the intervention operation is difficult, and the end member (110) is attached to the back member (110). When removing from the end of 7), the locking pieces (115) and (115) are pressed inward with one hand and the binding rod (9) a at the end position and the locking piece (115). There was a disadvantage in use that the end member (110) had to be pulled out by grasping the end portion (13) with the other hand in the state where the engagement with and was released. Therefore, when an external force in the pulling-out direction is applied to the end member of the present application, the engagement with the binding rod at the end position is rather strengthened, and the end member can be easily attached and detached with a light force. An object of the present invention is to provide a binding device configured such that the end member removal operation can be performed with one hand.

Means for Solving the Problems The present application, in order to improve the disadvantages of the above-mentioned known ones, an insertion groove opened at the front and rear end faces of the back plate in the central portion of the long back plate, the left and right positions of the back plate. A back member formed with a pair of locking grooves open at the front and rear end surfaces and right and left side surfaces respectively, and a tip end portion of the other locking member on the outer edge of a long connecting rod that intervenes in the one locking groove. A binding member having a plurality of ring-shaped binding rods intervening in the groove, and a pair of end members attached to the front and rear ends of the back plate to hold the binding member on the back member, respectively. The end member is integrally provided on an upper surface of the insertion projecting piece that intervenes in the insertion groove of the back member at the center of the inner surface of the end plate, and extends outward from the front end in an inclined shape at the left and right positions. Together with the end plate, the end plate extends vertically and is integrally connected to the end plate. And a locking projection having symmetrically formed wings having stop recesses, and a slit split into two continuous from the end plate position to the insertion projection and the locking projection. In order to improve the opening of the mounted backing sheet, the upper and left end portions of the upper surface of the locking piece are inclined downward in the above, and in the above, preferably a split shape. The slit is formed in a flat triangular shape so as to open greatly at the end plate position, and in the above, in order to increase the bending force of the wing part, the wing part is provided with slits that are closed at the upper and lower ends to give the bending force. It was formed.

Action Then, connect the binding rod of the binding member to one locking groove of the back member,
Inserting the tips of the binding rods into the other locking grooves respectively, and holding the binding member with respect to the back member in the state where the binding member is engaged with the back member, the left and right end surfaces of the end plate are pinched to form slits. Insert the insertion protrusion into the insertion groove while pressing the insertion protrusion inward. Then, the wing portion easily intervenes inside the binding rod located at the end of the binding member in the longitudinal direction, and in this state, the insertion of the end member is continued,
If the acupressure is released while the end plate is in contact with the end face of the back plate,
The slit is restored, and by the restoring force, the locking concave portion is locked to the binding rod, the end member is attached to the binding member, and the end plate of the end member is in contact with the end surface of the back member. The binding member is held. In this state, for example, when the weight of the bound mount acts as an external force on the end member via the binding rod, an external force in the same direction, that is, inward is also applied to the edge of the locking recess. Then, the left and right parts of the locking projections divided by the slits are inclined so as to open outward respectively with the closed end of the slit as a fulcrum,
Since the direction of the inclination is the direction in which the locking recess is locked with the binding rod, there is no fear that the wing portion will unnecessarily slip out of the binding rod due to an external force. When the end member is removed, the left and right end surfaces of the end plate are gripped, and as described above, they are pressed in the closing direction of the slit to separate the locking recess from the binding rod,
By pulling out the end member in this state, the end member is removed from the end portion of the back member by one-handed operation. Further, when the left and right ends of the upper surface of the locking piece are inclined downward, it is possible to prevent the binding sheet from rising when it is opened, and the upper and lower ends that give the wings a bending force. When the slit is formed, a large bending force of the wing can be obtained,
This facilitates the mounting operation of the end member.
