Ear protection device
An apparatus comprising a first curved band portion and a second curved band portion. The first curved band portion has a first end, a second end, an inner curved side and an outer curved side. The first curved band portion defines a passageway between the first end and the second end of the first curved band portion. The passageway has a first opening. The second curved band portion has a first end, a second end, an inner curved side and an outer curved side. A motion-restraint portion is proximate to the first end of the second curved band portion. The first end of the second curved band portion is insertable into the first opening of the passageway of the first curved band portion. The first curved band portion has a range of motion within the passageway of the second curved band portion.
1. An ear protection device comprising:
a band, said band including a first end, a second end, a first locking protrusion located proximate to said first end, and a second locking protrusion located proximate to said second end, the band and the first locking protrusion being unitarily formed;
a band membrane, said band membrane covering a portion of said band;
a first ear cup portion, said first ear cup portion being configured to receive said first locking protrusion to fixedly couple the first ear cup portion to the band; and
a second ear cup portion, said second ear cup portion being configured to receive said second locking protrusion,
each of said first locking protrusion and said second locking protrusion including a barbed shape.
2. The ear protection device of claim 1 , wherein said first locking protrusion is configured to be inserted into and retained within said first ear cup portion.
3. The ear protection device of claim 1 , wherein said first ear cup portion is formed of a semi-rigid material, said first locking protrusion being configured to be inserted into and retained within said first ear cup portion.
4. The ear protection device of claim 3 , wherein said semi-rigid material is foam.
5. The ear protection device of claim 1 , further comprising:
a first ear cup membrane, said first ear cup membrane defining an interior configured to receive said first ear cup portion; and
a second ear cup membrane, said second ear cup membrane defining its own interior configured to receive said second ear cup portion.
6. An ear protection device, comprising:
a band having a first band member and a second band member, the first band member being slideably coupled to the second band member, the first band member including a first end portion and a second end portion opposite the first end portion, a locking protrusion located proximate to the first end portion of the first band member, the first band member and the locking protrusion being unitarily formed; and
an ear cup portion, the ear cup portion being configured to receive the locking protrusion, the locking protrusion including a barbed shape.
7. The ear protection device of claim 6 , further comprising:
a band membrane configured to cover at least a portion of the band.
8. The ear protection device of claim 6 , wherein the locking protrusion is configured to be inserted into and fixedly retained within the ear cup portion.
9. The ear protection device of claim 6 , wherein the ear cup portion is formed of a semi-rigid material, the locking protrusion is configured to be inserted into and fixedly retained within the ear cup portion.
10. The ear protection device of claim 9 , wherein the semi-rigid material is foam.
11. An ear protection device, comprising:
a band, the band including a first end, a second end, a first locking protrusion located proximate to the first end of the band, a second locking protrusion located proximate to the second end of the band, the first locking protrusion and the second locking protrusion extending from the band in substantially the same direction;
a first ear cup portion, the first ear cup portion being configured to receive the first locking protrusion to fixedly couple the first ear cup portion to the band, the first locking protrusion including a barbed shape; and
a second ear cup portion, the second ear cup portion being configured to receive the second locking protrusion.
12. The ear protection device of claim 11 , further comprising:
a band membrane configured to cover at least a portion of the band.
13. The ear protection device of claim 11 , wherein the first locking protrusion is configured to be inserted into and retained within the first ear cup portion.
14. The ear protection device of claim 11 , wherein the first ear cup portion is formed of a semi-rigid material, the first locking protrusion is configured to be inserted into and retained within the first ear cup portion.
15. The ear protection device of claim 14 , wherein the semi-rigid material is foam.
16. The ear protection device of claim 11 , wherein the band has a first band member and a second band member, the first band member is slideably coupled to the second band member.
17. The ear protection device of claim 11 , wherein the band and the first locking protrusion are unitarily formed.
