Abstract

A connection fastener includes a plurality of fasteners, a sheet-shaped connection portion and attaching portions. Each fastener includes a head portion provided at one end portion side and a tapered leading end portion provided at the other end portion side. The sheet-shaped connection portion is configured to connect the plurality of fasteners in a parallel direction. The attaching portions are separate from the connection portion attached to the fasteners such that each attaching portion covers at least one part of each leading end portion. The connection portion includes first holding portions and second holding portions. Each of the first holding portions is configured to support a head portion side of each fastener. Each of the second holding portions is configured to support at least one part of a circumferential surface of each attaching portion.

First claim

What is claimed is:

1. A connection fastener comprising:
a plurality of fasteners each of which includes a head portion provided at one end portion side and a tapered leading end portion provided at the other end portion side;
a sheet-shaped connection portion that is configured to connect the plurality of fasteners in a parallel direction; and
attaching portions that are separate from the connection portion and into which the fasteners are inserted such that each attaching portion covers at least one part of each leading end portion to of each of the plurality of fasteners,
wherein the connection portion includes:
first holding portions each of which is configured to support a head portion side of each fastener; and
second holding portions each of which is configured to support at least one part of a circumferential surface of each attaching portion.

2. The connection fastener according to claim 1 , wherein:
the connection portion includes second holding holes which support the attaching portions provided at the second holding portions, and first holding holes which support the head portion sides of the fasteners provided at the first holding portions.

3. The connection fastener according to claim 2 , wherein:
diameters of the second holding holes are larger than diameters of the first holding holes.

4. The connection fastener according to claim 2 , wherein:
opening widths of opening slits of the second holding holes are larger than opening widths of opening slits of the first holding holes.

5. The connection fastener according to claim 1 , wherein:
each of the fasteners includes a shank continuously provided between the head portion and the leading end portion; and
the second holding portions support the attaching portions at positions at which the second holding portions overlap the tapered leading end portions of the fasteners, when viewed from a side direction of the fastener.

6. The connection fastener according to claim 1 , wherein:
each of the fasteners includes a shank continuously provided between the head portion and the leading end portion; and
the second holding portions support the attaching portions at positions at which the second holding portions do not overlap the fasteners, when viewed from a side direction of the fastener.

7. The connection fastener according to claim 1 , wherein:
the connection portion is formed by bending one long sheet in a C shape;
the first holding portions, the second holding portions, and a band-shaped portion connecting the first holding portions and the second holding portions are formed on the same plane in the long sheet;
each of the fasteners includes a shank continuously provided between the head portion and the leading end portion; and
in an axial direction of the fastener, a length of the shank is shorter than a length of the band-shaped portion.

8. The connection fastener according to claim 7 , wherein:
each fastener includes a stepped portion at the shank; and
the stepped portion is formed such that an outer diameter of a leading end portion side is smaller than an outer diameter of the head portion side, and faces an upper edge portion of the attaching portion.

9. The connection fastener according to claim 1 , wherein
each of the attaching portions includes a fall-preventing shape for preventing the second holding portion from falling off.

10. The connection fastener according to claim 9 , wherein the fall-preventing shape is a tapered shape which diameter is gradually increased toward a leading end portion side of the fastener.

11. The connection fastener according to claim 9 , wherein the fall-preventing shape is a stepped shape formed by making a large diameter of the attaching portion in a leading end portion side of the fastener or a concave shape of a circumferential groove shape.

12. The connection fastener according to claim 9 , wherein the fall-preventing shape is a bulgy shape in which the attaching portion in the head side of the fastener is swollen in an outer circumferential direction or a large diameter shape formed by making a large diameter of the attaching portion in the head side of the fastener.

13. The connection fastener according to claim 1 , wherein each of the fasteners further include an under-head tapered portion under the head portion of each fastener and between the head portion and the tapered leading end portion; and
wherein at least part of the under-head tapered portion is exposed without being covered by the attaching portion.

14. The connection fastener according to claim 1 , wherein a leading end of each attaching portion extends beyond the tapered leading end portion of each fastener and an opening is provided at the leading end of each attaching portion.

15. The connection fastener according to claim 1 , wherein at the tapered leading end portion of each fastener a space is provided between an outer surface of the tapered leading end portion and an inner surface of each attaching portion.

16. A connection fastener comprising:
a plurality of fasteners each of which includes a head portion provided at one end portion side and a tapered leading end portion provided at the other end portion side;
a sheet-shaped connection portion that is configured to connect the plurality of fasteners in a parallel direction; and
attaching portions that are separate from the connection portion attached to the fasteners such that each attaching portion covers at least one part of each leading end portion and that are assembled to the plurality of fasteners,
wherein the connection portion includes:
first holding portions each of which is configured to support a head portion side of each fastener;
second holding portions each of which is configured to support at least one part of a circumferential surface of each attaching portion; and
each of the attaching portions includes a flange portion protruding in an outer circumferential direction below the second holding portion.

17. A connection fastener comprising:
a plurality of fasteners each of which includes a head portion provided at one end portion side and a tapered leading end portion provided at the other end portion side;
a sheet-shaped connection portion that is configured to connect the plurality of fasteners in a parallel direction; and
attaching portions that are separate from the connection portion attached to the fasteners such that each attaching portion covers at least one part of each leading end portion and that are assembled to the plurality of fasteners,
wherein the connection portion includes:
first holding portions each of which is configured to support a head portion side of each fastener; and
second holding portions each of which is configured to support at least one part of a circumferential surface of each attaching portion;
wherein each of the attaching portions includes a fall-preventing shape for preventing the second holding portion from falling off, and wherein the fall-preventing shape comprises at least one of:
a tapered shape which diameter is gradually increased toward a leading end portion side of the fastener; or
a stepped shape formed by making a large diameter of the attaching portion in a leading end portion side of the fastener or a concave shape of a circumferential groove shape; or
a bulgy shape in which the attaching portion in the head side of the fastener is swollen in an outer circumferential direction or a large diameter shape formed by making a large diameter of the attaching portion in the head side of the fastener.
