Abstract

A mounting tool includes a female member and a male member. The female member has first and second engagement grooves that arc inclined such that a distance therebetween increases toward one side, and a female-side locking projection disposed adjacent to the first engagement groove and protruding to a side of the second engagement groove. The male member has first and second rail portions that are simultaneously fittable into the first and second engagement grooves, and a male-side locking projection disposed adjacent to the first rail portion. The male-side locking projection is disposed so as to interfere with the female-side engagement protrusion while the first and second rail portions that are being fitted into the first and second engagement grooves move in an intermediate axis direction, and so as not to interfere with the female-side locking projection while the second rail portion is being slid along the second engagement groove.

First claim

What is claimed is:

1. A mounting tool comprising:
a female member having a first engagement groove and a second engagement groove that are inclined such that a distance between the first engagement groove and the second engagement groove increases toward one side of the female member, the first engagement move and the second engagement groove opening inward as viewed in a cross-sectional view of the female member, the female member further having a female-side locking projection that is disposed adjacent to the first engagement groove and protrudes toward a side of the second engagement groove from the first engagement groove, and
a male member having a first rail portion and a second rail portion that are simultaneously finable into the first engagement groove and the second engagement groove, the male member further having a male-side locking projection that is disposed adjacent to the first rail portion and that is disposed so as to interfere with the female-side engagement protrusion while the first rail portion and the second rail portion that are being fitted into the first engagement groove and the second engagement groove move in an intermediate axis direction between the first engagement groove and the second engagement groove, and so as not to interfere with the female-side locking projection while the second rail portion is being slid along the second engagement groove.

2. The mounting tool according to claim 1 , wherein
the male member and the female member are each formed by bending one sheet of metal plate.

3. The mounting tool according to claim 1 , wherein
an inclination angle of each of the first engagement groove and the second engagement groove with respect to the intermediate axis direction is 5° to 20°.

4. The mounting tool according to claim 1 , wherein
each of the first engagement groove and the second engagement groove includes an inner portion that has a curved cross-sectional shape.

5. The mounting tool according to claim 1 , wherein
a distal end edge of the female-side locking projection has an end portion corner which is disposed on the one side of the female member and is chamfered.

6. The mounting tool according to claim 1 , wherein
a distal end edge of the female-side locking projection is inclined such that a distance from an intermediate axis to the distal end edge increases as the distance between the first engagement groove and the second engagement groove increases, and the intermediate axis extends in the intermediate axis direction.

7. The mounting tool according to claim 1 , wherein
a distance from a distal end of the male-side locking projection to the second rail portion is smaller than a distance from a distal end of the female-side locking projection to an innermost portion of the second engagement groove, and
a distance from the distal end of the male-side locking projection to an intermediate axis that extends in the intermediate axis direction between the first rail portion and the second rail portion is larger than a distance from the distal end of the female-side locking projection to the intermediate axis.

8. A mounting tool comprising:
a female member having a first engagement groove and a second engagement groove that are inclined such that a distance between the first engagement groove and the second engagement groove increases toward one side of the female member, the female member further having a female-side locking projection that is disposed adjacent to the first engagement groove and protrudes toward a side of the second engagement groove from the first engagement groove, and
a male member having a first rail portion and a second rail portion that are disposed such that a distance between the first and second rail portions and inclinations of the first and second rail portions are complementary to the distance between the first and second engagement grooves and inclinations of the first and second engagement grooves, the male member further having a male-side locking projection that is disposed adjacent to the first rail portion,
the male-side locking projection partially overlapping with the female-side locking projection as viewed in an intermediate axis direction between the first engagement groove and the second engagement groove, in a state in which the first rail portion and the second rail portion are fitted into the first engagement groove and the second engagement groove, while the male-side locking projection does not overlap with the female-side locking projection as viewed in a direction along the second engagement groove in the state in which the first rail portion and the second rail portion are fitted into the first engagement groove and the second engagement groove.

9. The mounting tool according to claim 8 , wherein
the male member and the female member are each formed by bending one sheet of metal plate.

10. The mounting tool according to claim 8 , wherein
an inclination angle of each of the first engagement groove and the second engagement groove with respect to the intermediate axis direction is 5° to 20°.

11. The mounting tool according to claim 8 , wherein
each of the first engagement groove and the second engagement groove includes an inner portion that has a curved cross-sectional shape.

12. The mounting tool according to claim 8 , wherein
a distal end edge of the female-side locking projection has an end portion corner which is disposed on the one side of the female member and is chamfered.

13. The mounting tool according to claim 8 , wherein
a distal end edge of the female-side locking projection is inclined such that a distance from an intermediate axis to the distal end edge increases as the distance between the first engagement groove and the second engagement groove increases, and the intermediate axis extends in the intermediate axis direction.

14. The mounting tool according to claim 8 , wherein
a distance from a distal end of the male-side locking projection to the second rail portion is smaller than a distance from a distal end of the female-side locking projection to an innermost portion of the second engagement groove, and
a distance from the distal end of the male-side locking projection to an intermediate axis that extends in the intermediate axis direction between the first rail portion and the second rail portion is larger than a distance from the distal end of the female-side locking projection to the intermediate axis.

15. A speaker device comprising:
the mounting tool according to claim 1 , and
a speaker having a back surface to which one of the female member and the male member of the mounting tool is attached.

16. The speaker device according to claim 15 , further comprising
an additional mounting tool which includes an additional female member and an additional male member that are identical to the female member and the male member, respectively, wherein
one of the additional female member and the additional male member is fixed to the back surface of the speaker such that the mounting tool and the additional mounting tool are aligned in an aligning direction with a space therebetween.

17. The speaker device according to claim 15 , further comprising
an additional mounting tool which includes an additional female member having an arrangement reversed to an arrangement of the female member with respect to an intermediate axis extending in the intermediate axis direction, and an additional male member having an arrangement reversed to an arrangement of the male member with respect to the intermediate axis, wherein
one of the additional femal
