Abstract

A binding component includes ring back portions, first ring arm portions, second ring arm portions and a back part to which the ring back portions are connected. Each ring back portion, each first ring arm portion and each second ring arm portion forms an annular ring part. Each ring part includes fitting portions at places where the ring back portion and the first and second ring arm portions are connected. The fitting portions are configured to be fitted by an operation of opening and closing the first and second ring arm portions with hinge portions of the ring back portion. Each fitting portion includes at least one first fitting convex portion, at least one first fitting concave portion to engage with the first fitting convex portion, at least one second fitting convex portion and a second fitting concave portion to engage with the second fitting convex portion.

First claim

What is claimed is:

1. A binding component comprising:
ring back portions, each ring back portion having a first end and a second end, and configured to be a member of an annular ring part;
first ring arm portions, each first ring arm portion configured to be a member of the annular ring part and connecting to the first end of the ring back portion by a hinge portion;
second ring arm portions, each second ring arm portion configured to be a member of the annular ring part and connecting to the second end of the ring back portion by a hinge portion; and
a back part to which the ring back portions are connected at predetermined intervals,
wherein each annular ring part includes fitting portions (i) at a place where the first ring arm portion and the ring back portion are connected to each other and (ii) at a place where the second ring arm portion and the ring back portion are connected to each other, the fitting portions configured to fit together the first ring arm portion and the ring back portion, and the second ring arm portion and the ring back portion, by an operation of opening and closing the first ring arm portion and the second ring arm portion with (i) the hinge portion of the first end of the ring back portion as a support point and (ii) the hinge portion of the second end of the ring back portion as a support point,
each fitting portion comprises:
at least one first fitting convex portion at an end of the first ring arm portion or at an end of the second ring arm portion, said end of the first ring arm portion or the second ring arm portion being opposite to the first end or the second end of the ring back portion;
at least one first fitting concave portion at the first end of the ring back portion opposite to the first ring arm portion or at the second end of the ring back portion opposite to the second ring arm portion, the first fitting convex portion having a shape configured to be fitted into the first fitting concave portion, and the first fitting concave portion having a corresponding shape configured to receive the first fitting convex portion;
at least one second fitting convex portion at the first end of the ring back portion opposite to the first ring arm portion or at the second end of the ring back portion opposite to the second ring arm portion; and
at least one second fitting concave portion at the end of the first ring arm portion or at the end of the second ring arm portion, the second fitting convex portion having a shape configured to be fitted into the second fitting concave portion, and the second fitting concave portion having a corresponding shape configured to receive the second fitting convex portion, wherein

the first fitting convex portion includes a first convex-side load receiving surface at an outwardly facing surface opposite to the first fitting concave portion,
the first fitting concave portion includes a first concave-side load receiving surface at an inwardly facing surface opposite to the first convex-side load receiving surface,
the second fitting convex portion includes a second convex-side load receiving surface at an outwardly facing surface opposite to the second fitting concave portion,
the second fitting concave portion includes a second concave-side load receiving surface at an inwardly facing surface opposite to the second convex-side load receiving surface,
the first fitting convex portion includes a third convex-side load receiving surface at a surface facing an axial direction of the annular ring part opposite to the first fitting concave portion, and
the first fitting concave portion includes a third concave-side load receiving surface at a surface facing an axial direction of the annular ring part opposite to the third convex-side load receiving surface.

2. The binding component according to claim 1 ,
wherein two second fitting concave portions are, respectively, provided at both sides of one first fitting convex portion in a width direction of the first ring arm portion and the second ring arm portion, the width direction of the first ring arm portion and the second ring arm portion being an axial direction of the first ring arm portion and the second ring arm portion, and
two second fitting convex portions are, respectively, provided at both sides of one first fitting concave portion in a width direction of the ring back portion, the width direction of the ring back portion being an axial direction of the ring back portion.

3. The binding component according to claim 1 ,
wherein the first fitting convex portion and the second fitting concave portion are provided in an alternating manner along a width direction of the first ring arm portion and the second ring arm portion, the width direction of the first ring arm portion and the second ring arm portion being an axial direction of the first ring arm portion and the second ring arm portion, and
the first fitting concave portion and the second fitting convex portion are provided in an alternating manner in a width direction of the ring back portion, the width direction of the ring back portion being an axial direction of the ring back portion.

4. The binding component according to claim 1 ,
wherein each of the first fitting convex portion and the second fitting convex portion has a shape and a size so that the first fitting convex portion and the second fitting convex portion are configured to be fitted into a clearance, the clearance being formed between adjacent binding components which are stacked in a stack direction in a state where the first ring arm portion and the second ring arm portion in each binding component are open and a plurality of binding components are stacked in the stack direction.

5. The binding component according to claim 1 ,
wherein at least two slits are provided in the ring parts which are located, at least, at both ends in an extension direction of the back part, each slit being formed in the ring back portion by an opening which penetrates an inner peripheral side and an outer peripheral side of the ring back portion.
