Abstract

A fastener member 10 is provided with a base portion 11 having a main surface 15 , and a plurality of engaging members 12 provided upright on the main surface 15 , in which mechanical coupling with a loop member 30 is achieved by causing the engaging members 12 to engage the loop member 30 . The fastener member 10 is provided with an arm portion 13 disposed on the base portion 11 via a base connection portion 13 a such that a tip side can pivot in a direction so as to approach the main surface 15 , a claw portion 18 that is provided to the arm portion 13 , and a hook-shaped protruding portion 14 provided to the base portion 11 . The claw portion 18 and the hook-shaped protruding portion 14 latch onto one another when the fastener member 10 and the loop member 30 are coupled. The tip side of the arm portion 13 is positioned to a position opposite the main surface 15 away from the tips of the engaging portions 12 when the fastener member 10 and the loop member 30 are not coupled.

First claim

What is claimed is:

1. A fastener member comprising:
a base portion having a surface; and a plurality of engaging members vertically provided on the surface, the engaging members being mechanically coupled to a coupling target by engaging the engaging members with the coupling target;
an arm portion disposed on the base portion via a base connection portion such that a tip side can pivot in a direction so as to approach the surface;
a claw portion provided on the arm portion; and
a latching portion provided on the base portion that engages the claw portion when the coupling target is coupled,
the tip side of the arm portion being positioned to a side opposite the surface away from tips of the engaging members when the coupling target is not coupled.

2. The fastener member according to claim 1 , wherein the claw portion has a shape that extends so as to bend in a hook shape from the tip of the arm portion, and
the latching portion is a hook-shaped protrusion that protrudes in a hook shape relative to the surface.

3. The fastener member according to claim 2 , wherein the arm portion includes first and second arm portions, and
the first and second arm portions are arranged in parallel along a predetermined direction with the base portions of the first and second arm portions oriented so as to be adjacent to each other when viewed from the surface.

4. The fastener member according to claim 2 , wherein the latching portion abuts the claw portion so as to restrict pivoting of the arm portion when not coupled with the coupling target, and
an abutting face between the latching portion and the claw portion has a curved face or an inclined face that inclines relative to the surface.

5. The fastener member according to claim 2 , wherein the tip side of the arm portion has flexibility such as to enable pivoting in a direction so as to be separated away from the surface.

6. The fastener member according to claim 1 , wherein the arm portion includes first and second arm portions, and
the first and second arm portions are arranged in parallel along a predetermined direction with the base portions of the first and second arm portions oriented so as to be adjacent to each other when viewed from the surface.

7. The fastener member according to claim 6 , wherein the latching portion abuts the claw portion so as to restrict pivoting of the arm portion when not coupled with the coupling target, and
an abutting face between the latching portion and the claw portion has a curved face or an inclined face that inclines relative to the surface.

8. The fastener member according to claim 6 , wherein the tip side of the arm portion has flexibility such as to enable pivoting in a direction so as to be separated away from the surface.

9. The fastener member according to claim 1 , wherein the latching portion abuts the claw portion so as to restrict pivoting of the arm portion when not coupled with the coupling target, and
an abutting face between the latching portion and the claw portion has a curved face or an inclined face that inclines relative to the surface.

10. The fastener member according to claim 9 , wherein the tip side of the arm portion has flexibility such as to enable pivoting in a direction so as to be separated away from the surface.

11. The fastener member according to claim 1 , wherein the tip side of the arm portion has flexibility such as to enable pivoting in a direction so as to be separated away from the surface.

12. The fastener member according to claim 1 , wherein a clicking feeling is produced, when the claw portion is latched by the latching portion.
