A waterproof camera case includes first and second case members and a lock mechanism for locking the first and second case members together. The lock mechanism includes a side flip hingedly connected to a side of the rear case member and moveable between a flip open position and a flip closed position where an inner surface of the side flip abuts against a side of the front case member. A press member is pivotable about a first shaft mounted on the inner surface of the side flip and moveable between a non-pressing position and a pressing position. A free distal side of the press member is configured to press against a ledge projected from the side of the front case member on a surface oppositely facing the rear case member. A lock member is slidable along a second shaft mounted on the inner surface of the side flip and moveable between an unlocked position and a locked position. The lock member has a latch portion adapted to insert into a slot defined by a catch portion formed on the side of the front case member. A torsion spring is used to bias the press member in the non-pressing position, and a compression spring is used to bias the lock member in the locked position.

1. A waterproof camera case comprising first and second case members and a lock mechanism for locking the first and second case members together, the lock mechanism comprising: (a) a side flip hingedly connected to a side of the first case member and moveable between a flip open position and a flip closed position where an inner surface of the side flip abuts against a side of the second case member;(b) a press member pivotable about a first shaft mounted on the inner surface of the side flip and moveable between a non-pressing position and a pressing position, a free distal side of the press member pressed against a ledge projected from the side of the second case member on a surface oppositely facing first case member; and(c) a lock member slidable along a second shaft mounted on the inner surface of the side flip and moveable between an unlocked position and a locked position, the lock member comprising a latch portion inserted into a cavity defined by a catch portion formed on the side of the second case member;a torsion spring coupled to the first shaft for biasing the press member in the non-pressing position at an acute angle with respect to the side flip;wherein the ledge is projects outwardly from a flip-engaging side of the first case member, the ledge is integrally formed proximate to and along an edge of the first case member; when the first case member covers the second case member and flips the side flip from the flip open position to the flip closed position, a free distal edge or side of the press member press against the surface of the ledge facing away from the second case member;wherein when a user flips the side flip from the flip open position to the flip closed position, the press member pivots towards and abuts against the inner surface of the side flip; wherein when the side flip is moved from the flip closed position to the flip open position, the press member returns to its non-pressing position as the torsion spring springs back to its normal position thereby biasing the press member in the non-pressing position; wherein the torsion spring is disposed within a central slot of the press member; the torsion spring has a coiled section and two free ends; the coiled section is mounted around the first shaft; one free end is held in position by a pair of brackets integrally formed on the inner surface of the side flip, and the other free end is held in position within a groove formed on an inner surface of the press member. 2. The waterproof camera case as claimed in claim 1, further comprising a compression spring mounted on the second shaft for biasing the lock member in the locked position. 3. The waterproof camera case as claimed in claim 1, wherein the press member is generally in the shape of an elongated rectangular bar, and the free distal side of the press member is elongated in shape for pressing against an elongated groove formed on the ledge. 4. The waterproof camera case as claimed in claim 3, wherein the elongated free distal side has a convex cross section, and the elongated groove has a complementary concave cross section. 5. The waterproof camera case as claimed in claim 1, wherein the latch portion has a first curved surface for engagement with a second curved surface on the catch portion, whereby when the side flip is moved from the flip open position towards the flip closed position, the first curved surface presses against the second curved surface thereby forcing the lock member to move towards the unlocked position until the latch portion passes the catch portion and inserts into the cavity when the lock member is pushed from the unlocked position to the locked position under the influence of the compression force of the compression spring. 6. The waterproof camera case as claimed in claim 1, further comprising a switch portion integrally formed on the lock member and disposed generally through an opening of the side flip for manually switching the lock member from the locked position to the unlocked position thereby releasing the side flip from the flip closed position. 7. The waterproof camera case as claimed in claim 1, wherein the first shaft is parallel to a pivot axis about which the side flip pivots with respect to the first case member. 8. The waterproof camera case as claimed in claim 1, wherein the first and second shafts are parallel to each other. 9. The waterproof camera case as claimed in claim 1, wherein the side flip is hingedly connected to one side of the first case member opposite to the side of the first case member which is hingedly connected to the second case member. 10. The waterproof camera case as claimed in claim 1, wherein the width of the side flip is substantially equal to the width of the side of the second case member.
