Abstract

A staple includes a crown section including a first curve, a second curve, a third curve, a first straight segment extending between the first curve and the second curve, and a second straight segment extending between the first curve and the third curve. The second curve and the third curve define, respectively, opposite ends of the crown section. The staple includes a pair of leg sections extending from the opposite ends of the crown section.

Claims (29)

1 . A staple comprising:

a crown section including a first curve, a second curve, and a third curve, a first straight segment extending between the first curve and the second curve, and a second straight segment extending between the first curve and the third curve, the second curve and the third curve defining, respectively, opposite ends of the crown section; and

a pair of leg sections extending from the opposite ends of the crown section.

2 . The staple of claim 1 , wherein the crown section has a diamond shape, wherein the first, the second, and the third curves represent three points of a diamond.

3 . The staple of claim 1 , wherein the first straight segment defines a first segment length between the first curve and the second curve, wherein the second straight segment defines a second segment length between the first curve and the third curve, and wherein the first and the second segment lengths are equal.

4 . The staple of claim 1 , wherein each of the first curve, the second curve, and the third curve is defined by an identical radius.

5 . The staple of claim 1 , wherein the first curve is positioned at an apex of the crown section that is bisected by a central plane of symmetry, and wherein the first and second straight segments are oriented from the central plane of symmetry at an oblique angle.

6 . The staple of claim 5 , wherein the oblique angle is in a range from 40 degrees to 50 degrees.

7 . The staple of claim 1 , wherein the leg sections include leg segments that extend from the crown section and are parallel with each other.

8 . The staple of claim 1 , wherein the crown section has an outer width that is greater than an outer width of the leg sections.

9 . The staple of claim 1 , further comprising a barb projecting outward from each of the leg sections in a widthwise direction.

10 . A staple comprising:

a crown section having opposite ends, and

a pair of leg sections extending from the opposite ends of the crown section away from the crown section, each of the pair of leg sections including a distal end having an inclined face and a curved surface,

wherein the inclined face has an edge that is adjacent the curved surface.

11 . The staple of claim 10 , wherein the leg sections include leg segments that extend from the crown section that are parallel with each other.

12 . The staple of claim 10 , wherein the crown section is bisected by a central plane of symmetry, wherein the leg sections include leg segments that extend from the crown section and are parallel with the central plane of symmetry.

13 . The staple of claim 10 , wherein the crown section is bisected by a central plane of symmetry, wherein the leg sections include leg segments that extend from the crown section and are oriented relative to the central plane of symmetry at an oblique angle.

14 . The staple of claim 10 , wherein the crown section has a diamond shape, with a first curve, a second curve, and a third curve representing three points of a diamond.

15 . The staple of claim 10 , wherein the crown section is bisected by a central plane of symmetry with one leg section on each side of the central plane; wherein the crown section and the pair of leg sections are bisected by a middle plane that is perpendicular to the central plane of symmetry, and wherein the inclined face is oriented relative to the middle plane at an oblique angle.

16 . The staple of claim 10 , further comprising barb projecting outward from each of the leg sections in a widthwise direction.

17 . The staple of claim 16 , further comprising a recessed area extending into each of the leg sections in the widthwise direction.

18 . A staple comprising:

a crown section having a diamond shape with a first curve positioned at an apex of the crown section, a second curve, and a third curve representing three points of a diamond, the second curve and the third curve defining, respectively, opposite ends of the crown section; and

a pair of leg sections extending from the opposite ends of the crown section,

wherein the second curve and the third curve define a maximum width of the crown section, and

wherein the opposite ends of the crown section define an end width that is smaller than the maximum width of the staple.

19 . The staple of claim 18 , wherein the leg sections include leg segments that are parallel with each other.

20 . The staple of claim 18 , wherein each of the first curve, the second curve, and the third curve is defined by an identical radius.
