Waterproof case
View Patent ↗There is provided a waterproof case which prevents ingress of water into the waterproof case through a protection piece, including a case body formed into a rectangular tube-like shape with a peripheral wall thereof and a lower cover having a bottom wall covering a lower opening of the case body and a peripheral wall extending from the bottom wall. The peripheral wall of the body case is placed so as to cover the peripheral wall of the lower cover. The protection piece is provided at the peripheral wall of the lower cover so as to sandwich the peripheral wall of the case body with the peripheral wall of the lower cover to prevent the deformation of the peripheral wall of the lower cover. There is also provided a protrusion protruding from a surface of the peripheral wall of the case body on which the protection piece is placed.
1. A waterproof case comprising,
a case body formed with a peripheral wall of the case body,
a cover having a bottom wall and a peripheral wall extending perpendicularly from the bottom wall,
the bottom wall covering an opening formed by an edge of the peripheral wall of the case body,
the peripheral wall of the cover being arranged adjacent to the peripheral wall of the case body in an overlapping manner, and
a protection piece extending from the peripheral wall of one of the cover and the case body,
the one of the cover and the case body being located at a lower position in a vertical direction with respect to the other one of the cover and the case body, wherein
the protection piece is arranged such that a lower end portion of the peripheral wall of the other one of the cover and the case body is sandwiched between the protection piece and the peripheral wall of the one of the case body and the cover so that the protection piece prevents the peripheral wall of the one of the case body and the cover from being deformed inward, and wherein
a protrusion is provided at the peripheral wall of the other one of the case body and the cover,
the protrusion being arranged to protrude with respect to a surface of the other one of the case body and the cover on which the protection piece is placed such that a lower end surface of the protrusion is arranged on an upper end surface of the protection piece.
2. The waterproof case according to claim 1 , wherein
the protection piece is provided with a through hole formed at a lower end portion of the protection piece.
3. The waterproof case according to claim 2 , wherein
the protection piece is provided with a thick portion projecting outwardly and arranged around the through hole.
4. The waterproof case according to claim 1 , wherein
the cover is located at a lower position than that of the case body in the vertical direction.
5. The waterproof case according to claim 1 , wherein
the protection piece is placed on the surface of the cover.
6. The waterproof case according to claim 1 , wherein
the protrusion is arranged on the surface of the case body.
7. The waterproof case according to claim 1 , wherein
the protrusion is arranged to protrude from a surface of the protection piece.
8. The waterproof case according to claim 1 , wherein
the protection piece comprises:
a bottom wall portion;
a plurality of reinforcing ribs; and
a protection body.
9. The waterproof case according to claim 8 , wherein
the ribs are arranged in parallel with respect to each other and perpendicular with respect to both of the bottom wall portion and the peripheral wall of the cover.
10. The waterproof case according to claim 8 , wherein
the protection body extends upward from the bottom wall so as to be placed on an outer surface of the lower end portion of the peripheral wall of the case body.
