Abstract: The travel case contains a case body and a number of wheels configured on a bottom side of the case body. The case body contains a front member, a back member; a telescoping handle and a first static handle on the top side, and a second static handle on a second lateral side opposite to the first lateral side of the case body. The front and back members are hinged along the first lateral side jointly forming a storage space for traveling items. Both the front and back members have slant top corners, therefore achieving six circumferential sides. Both a front side of the front member and a back side of the back member are configured with indentations and protrusions of various shapes. Due to the six circumferential sides from the slant corners, and the indentations and protrusions, the travel case has superior durability and robustness.

Abstract: A suitcase lock includes a housing forming a slot. A link bar is mounted to inside of the housing. A lid is mounted to an inner open side of the housing by the link bar pivoted to the lid. A push switch, a rotor, and a hook block are arranged on the lid. The assembled lock is mounted to a suitcase so that the hook block may engage a counterpart hook formed in an upper shell of the suitcase and a pawl of the push switch engages the lid and the rotor is set at a position abutting against the push switch to thereby prevent the upper shell from opening. When the rotor is operated so as to not abut against the push switch, the push switch is inward depressible to disengage the pawls from each other, to thereby allow the upper shell to be opened.
