The cover portion 102 extends toward the side 106 and extends toward the side that is opened from the second hinge portion 116 on the interposition portion 106 side of the second protruding sheet 114.
Since the synthetic resin sheets constituting the front cover portion 102, the back cover portion 104, the interposition portion 106, and the protruding portion 108 have elasticity, the first protruding sheet 110 and the second protruding portion try to return to the original shape. The sheet 114 acts so that the opposed surface is separated from the leading edge 120, and the opposed surface is separated from the second projecting sheet 114 and the front cover 102 with the second hinge part 116 as the center. Act on.
The protruding portion 108 is in contact with the inside of the first sandwiching body 20 or the second sandwiching body 22 when the cover member 100 is sandwiched between the sandwiching tool 12 and the insertion portion 26 of the first sandwiching body 20 and the second sandwiching body 22. On the opposite side, the cover member 100 and the cover member 100 are formed so as to be guided toward an area wider than the insertion portion 26, and after the cover member 100 is sandwiched between the clamping members 12, the cover member 100 is inserted. Is formed so as not to come out of the holding tool 12.
As described above, the synthetic resin sheet includes an equivalent such as paper, resin-impregnated paper, a laminated material of the synthetic resin sheet and paper, and the like having elasticity that can be bent.

  The binding rod member 14 is inserted into the insertion rod 40 so as to be inserted into the binding hole S1 of the article S to be bound and the first binding rod insertion hole 28 of the first holding body 20 so as to be locked around the insertion rod. The locking head 42 formed on one end of the portion 40 and a portion on the outer surface of the insertion collar 40 at a position separated from the locking head 42 with a gap corresponding to the thickness of the first sandwiching body 20. It has a latching and retaining portion 44 that protrudes and is integrally formed of polyacetal resin.

  The first clamping body 20 of the clamping tool 12 is provided with a first binding rod insertion hole 28 for inserting the insertion collar portion 40 of the binding member 14 inserted into the binding hole S1 of the binding object S. The second clamping body 22 of the clamping tool 12 is inserted into the first binding rod insertion hole 28 of the first clamping body 20 and is inserted into the binding hole S1 of the binding object S. A second binding rod insertion hole 30 for inserting the distal end portion is provided therethrough.

The first clamping body 20 is inserted into the outer periphery of the first binding rod insertion hole 28 with a latching stopper portion for inserting the latching stopper portion 44 of the binding member 14 following the first binding rod insertion hole 28. A hole 32 is formed. The latching / unlocking part insertion holes 32 are semicircular in plan view, and are formed in pairs in the longitudinal direction of the first holding body 20. The divided latching / unlocking part insertion holes 32 and the latching / unlocking part insertion holes 32 are defined as follows. It is formed so as to have two-fold rotational symmetry (symmetry that coincides with the original figure when half of one rotation is made).
In the vicinity of the divided latching / preventing part insertion hole 32 and the latching / preventing part insertion hole 32, that is, in the longitudinal direction of the first clamping body 20, the latching / preventing part insertion hole 32 and the latching are provided on the front side and the far side. A pair of projecting portions 36 and the projecting portions 36 protrude from the retaining portion insertion hole 32 at a distance. The convex portion 36 is formed to lock and fix the binding member 14 to the first holding body 20.
Further, the first clamping body 20 is formed in a region other than the area where the latching / unlocking part insertion hole 32 is formed, that is, the edge of the first binding rod insertion hole 28 and the latching / unlocking part insertion hole 32 is formed. A locking region for locking the latching and retaining portion 44 is formed in a region other than the region.

On the outer surface of the first clamping body 20, a stepped portion 34 that receives the locking head 42 of the binding member 14 is formed around the first binding device insertion hole 28.
The step portion 34 is formed with a guide portion 34a having a convex surface on the inner surface so that the height of the one end on the insertion side for inserting the binding object S increases toward the center of the free end. When the binding object S is inserted and slid into the holding tool 12 together with the object to be bound S from the insertion portion 26 in order to sandwich the binding material S in the cover member 100, the leading edge 120 of the protruding portion 108 of the cover member 100 comes into contact with the insertion member 26. Guiding toward the wider connecting portion 24 side facilitates insertion of the cover member 100. The guide portion 34a is formed continuously from the far side to the near side in the length direction of the first sandwiching body 20, and faces the continuous portion 24 that protrudes from the continuous portion 24 side toward the insertion portion 26 side. Provided with a ridge inclined surface.

The first clamping body 20 and the binding member 14 are arranged between the locking head 42 of the binding member 14 and the latching retaining portion 44 of the binding member 14 inserted into the first binding hole 28. A substantially circular first binding hole 28 having a diameter slightly longer than the diameter of the insertion collar 40 is formed so that the insertion collar 40 and the first clamping body 20 are fixed substantially orthogonally. Yes.
In addition, the second clamping body 22 is configured so that the insertion collar portion 40 of the binding member 14 can be used regardless of whether the interval between the insertion portions 26 between the first clamping body 20 and the second clamping body 22 is wide or narrow. A substantially elliptical second binding rod insertion hole 30 having a long diameter (long axis) longer than the diameter of the insertion collar portion 40 is formed so as to be inserted.
The second binding rod insertion hole 30 is formed such that its long diameter (long axis) extends in the width direction of the second sandwiching body 22.

The locking head 42 includes a substantially elliptical substrate 42a having a length that is longer than the length of the first binding rod insertion hole 28 of the holding tool 12, and the center of the upper surface of the substrate 42a (insertion flange 40). And a long groove 42c extending toward the short axis side of the substrate 42a at the center of the circular bulged portion 42b in a plan view circular shape. The back surface (lower surface) of the substrate 42a has a flat surface portion 42d for smoothly rotating the locking head 42 while being in close contact with the upper surface of the first sandwiching body 20 so as to extend along the major axis of the substrate 42a. An inclined surface portion 42e and an inclined surface portion 42e are formed symmetrically on both sides of the flat portion 42d, that is, in the vicinity of both end edges in the minor axis (short axis) direction of the substrate 42a.
The long groove 42c is a groove extending in the protruding direction of the latching and retaining portion 44, and has a width corresponding to the thickness of the disk-shaped rotation assisting tool C such as a coin.

A pair of left and right latching stoppers 44 is formed, and the left and right latching stoppers 44 and the latching stoppers 44 are axially symmetrical when rotated 180 degrees around the insertion collar 40 (twisted rotation). Both when the interval of the insertion portion 26 between the first sandwiching body 20 and the second sandwiching body 22 is wide and narrow, is accommodated in the binding hole S1 of the binding object S. In such a height, the insertion hook 40 protrudes in a direction perpendicular to the axial direction of the insertion hook 40.
The top surface of the latching / unlocking portion 44 facing the back surface of the latching / unlocking portion 44 is formed in an arc shape in order to facilitate the rotation of the insertion collar portion 40, and is the front end side of the insertion collar portion 40. The lower portion is lowered toward the lower side in order to facilitate the insertion into the first binding rod insertion hole 28.

In addition, the binding object S is composed of a group of paper notes on which paper notes are stacked. When the thickness of the binding object S is thick, the interval of the insertion portion 26 between the first sandwiching body 20 and the second sandwiching body 22 is small. The angle becomes such that the second sandwiching body 22 and the insertion flange 40 are substantially orthogonal to each other, and the hole edge of the binding hole S1 of the binding object S is also substantially parallel.
On the other hand, when the thickness of the object to be bound S is thin, the interval of the insertion portion 26 between the first sandwiching body 20 and the second sandwiching body 22 is narrowed, and the second sandwiching body 22 and the insertion flange 40 are obliquely crossed. The angle is such that it also crosses with the hole edge of the binding hole S1 of the binding object S.
The diameter of the binding hole S1 is determined by a standard (for example, Japanese Industrial Standard JIS).
Thus, the shape of the insertion collar portion 40 of the binding member 14 and the shape of the latching retaining portion 44 prevent the binding member 14 from being inserted into the binding hole S1 of the binding object S. In addition, even if the second sandwiching body 22 and the insertion hook 40 are obliquely crossed, even if it approaches the hole edge of the binding hole S1 of the binding object S, the insertion hook is not touched at all. It is necessary to define the width in a direction orthogonal to or oblique to the 40 axial direction so as to be accommodated in the binding hole S1 of the binding object S.

The binding member 14 is recessed on the lower surface of the locking head 42 fixed to the first binding body insertion hole 28 of the first sandwiching body 20, that is, on the surface facing the outer surface of the first sandwiching body 20. 46 is formed, and the concave portion 46 of the binding member 14 is fitted to the convex portion 36 projecting from the outer surface of the first sandwiching body 20 to be fixed to the first sandwiching body 20.
The binding member 14 can be rotated in the first binding rod insertion hole 28 around the insertion flange portion 40, and smoothly without contacting the convex portion 36 by the inclined surface portion 42e on the back surface (lower surface) of the substrate 42a. The concave portion 46 of the binding member 14 can be fitted to the convex portion 36 protruding from the outer surface of the first sandwiching body 20.
As described above, the binding member 14 has an axial symmetry that matches the original figure when the binding member 14 is rotated about one half of one rotation around the insertion flange 40 (axis).

When the binding object S is relatively soft, such as a paper note, the cover member 100 is overlapped on the front and back surfaces of the binding object S.
In the vicinity of the binding margin side edge of the front cover portion 102 and the back cover portion 104, a front cover portion binding hole 130 and a back cover portion binding hole 132 are formed at the same position as the binding hole S1 of the binding object S. . The front cover part binding hole 130 of the front cover part 102 and the back cover part binding hole 132 of the back cover part 104 can be inserted into the insertion collar part 40 and the latching retaining part 44 of the binding member 14. The shape and position are configured. The front cover part binding hole 130 and the back cover part binding hole 132 are configured to be aligned with the object to be bound S and the binding hole S1.

Then, the object to be bound S sandwiched between the front cover portion 102 and the back cover portion 104 of the cover member 100 is fitted by sliding the binding margin side together with the cover member 100 to the insertion portion 26 of the holding tool 12. Let me insert it.
At this time, the protruding portion 108 of the cover member 100 is located on the open side opposite to the sandwiched side at the (longitudinal) edge of the sandwiched side of the front cover unit 102 and / or the back cover unit 104. (Longitudinal) It protrudes toward the edge and has a length that is accommodated inside the insertion portion 26 of the first sandwiching body 20 (or the second sandwiching body 22). In particular, the leading edge of the projecting portion 108 of the cover member 100 Since 120 is formed so as to be in contact with the inner side surface (surface on the side of the connecting portion 24) of the convex guide on the inner surface of the step 34 of the first sandwiching body 20, the leading edge 120 extends along the guide portion 34a. It is inserted and pushed toward the connecting portion 24 wider than the insertion portion 26 and guided.
Thus, the cover member 100 that slides the sandwiching tool 12 relatively lightly and smoothly and sandwiches the object to be bound S is inserted, and the cover member 100 is interposed between the first sandwiching body 20 and the second sandwiching body 22. It is clamped with the object S to be bound.

Then, the insertion hook portion 40 of the binding member 14 is inserted into the binding hole S1 of the binding object S held by the holding tool 12 from the first binding pin insertion hole 28 of the first holding body 20, and the binding member 14 is inserted. Is inserted into the latching / unlocking portion insertion hole 32 of the first clamping body 20 and entangled in the second binding rod insertion hole 30 of the second clamping body 22. The neck 40a between the locking head 42 and the latching retaining part 44 is squeezed into the first binding hole 28 of the first holding body 20 so that the locking head 42 is turned 90 degrees. Then, the concave portion 46 provided on the back surface (lower surface) of the locking head portion 42 is fitted into the convex portion 36 provided on the outer surface of the first sandwiching body 20.
Thus, the binding member 14 can fix the binding object S to the clamping tool 12 in a state of straddling the first clamping body 20 to the second clamping body 22.

The binding tool can be variously changed based on the idea of the present invention.
For example, it is possible to variously change the shape of the protrusions of the holding tool and the cover member.

The sandwiching tool 12 includes a first sandwiching body 220 that holds one surface of the binding object S, a second sandwiching body 222 that holds the other surface of the binding object S, and a first sandwiching body 220 and a second sandwiching body 222. The first sandwiching body 220 and the second sandwiching body 222 that face each other are connected by the connecting section 224 and on the opposite side of the connecting section 224. The insertion part 226 which is an opening part is formed in each free end of the clamping body 20 and the 2nd clamping body 22, and the whole is integrally molded by the polyacetal resin which has elasticity, for example.
The first sandwiching body 220 and the second sandwiching body 222 have a first lip-shaped edge 220a and a second lip-shaped edge 222a having a substantially circular cross section at the free end on the insertion portion 226 side. The first lip-shaped edge 220a of the first clamping body 220 and the second lip-shaped edge 222a of the second clamping body 222 are in contact with each other when the binding object S is not bound, and when the binding object S is bound, The binding S is sandwiched from the front side and the back side and pressed by elasticity.
In this example, the binding member 14 is not provided, and the first binding rod insertion hole 28, the second binding rod insertion hole 30, and the latching and retaining portion insertion hole 32 are not provided.

Then, the object to be bound S sandwiched between the front cover portion 102 and the back cover portion 104 of the cover member 100 is fitted by sliding the binding margin side together with the cover member 100 to the insertion portion 226 of the holding tool 212. Let me insert it.
At this time, the protruding portion 108 of the cover member 100 is located on the open side opposite to the sandwiched side at the (longitudinal) edge of the sandwiched side of the front cover unit 102 and / or the back cover unit 104. (Longitudinal) It protrudes toward the edge and has a length that is accommodated inside the insertion portion 226 of the first sandwiching body 220 (or the second sandwiching body 222). In particular, the leading edge of the projection 108 of the cover member 100 Since 120 is formed so as to be in contact with the inner side surface (surface on the side of the connecting portion 24) of the protrusion on the inner surface of the step 34 of the first sandwiching body 220, the leading edge 120 extends along the guide portion 234a. Then, it is pushed and guided toward the connecting portion 224 that is wider than the insertion portion 226.
Thus, the cover member 100 in which the object to be bound S is sandwiched by sliding the holding tool 212 relatively lightly and smoothly is inserted, and the cover member 100 is interposed between the first holding member 220 and the second holding member 222. It is clamped with the object S to be bound.
The front cover member 100 and the object to be bound S that are sandwiched are unlikely to come out of the sandwiching tool 212 because the leading edge 120 of the projecting portion 108 abuts against the inner surface of the guide portion 234a.
