Hinge device for storage container and storage container having the same

A hinge device for a storage container, which enables a door of the storage container to swingably couple to a container body, the hinge device comprising:

• a housing mounted on any one of the door and the container body;
• a hinge shaft rotatably fitting at one end thereof in an end of the housing, and outwardly extending at a remaining end thereof from the housing to couple to a remaining one of the door and the container body;
• and
• a shock-absorbing unit provided between an inner surface of the housing and an outer surface of the hinge shaft such that a portion of the shock-absorbing unit is formed on the outer surface of the hinge shaft, so as to increase a resistance to a rotation of the hinge shaft when the door is being closed.

A storage container including a container body having a storage chamber with a top thereof being opened, a door to close the container body, and a hinge device to enable the door to swingably couple to the container body, the hinge device comprising:

• a housing mounted on any one of the door and the container body;
• a pair of hinge shafts rotatably fitting in opposite ends of the housing, the pair of hinge shafts including cam shaft parts with first cams provided on outer circumferential surfaces of the cam shaft parts, respectively, and extension shaft parts outwardly extending from the cam shaft parts, respectively, to coupled to a remaining one of the door and the container body;
• a pair of movable members, which are received in the opposite ends of the housing, and fitting on the cam shaft parts of the hinge shafts, respectively, so as not to rotate with respect to the housing, the pair of movable members having second cams to engage with the first cams, respectively;
• and
• a pair of compression springs disposed in the opposite ends of the housing to bias the pair of movable members toward the pair of first cams, respectively.

A storage container including a container body having a storage chamber with a top thereof being opened, a door to close the container body, and a hinge device to enable the door to swingably couple to the container body, the hinge device comprising:

• a housing mounted on any one of the door and the container body;
• a hinge shaft rotatably fitting at one end thereof in an end of the housing, and outwardly extending at another end thereof from the housing to couple to a remaining one of the door and the container body;
• and
• a shock-absorbing unit provided between an inner surface of the housing and an outer surface of the hinge shaft such that a portion of the shock-absorbing unit is formed on the outer surface of the hinge shaft, so as to increase a resistance to a rotation of the hinge shaft when the door is being closed.

A hinge device to rotatably couple a door to a main body, comprising:

• a housing mounted on any one of the door and the main body;
• plural hinge shafts rotatably fitting in respective ends of the housing, each of the hinge shafts including a cam shaft part with a first cam provided thereon, and a respective extension shaft part extending from the cam shaft part, to couple to a remaining one of the door and the main body;
• plural movable members, received in the respective ends of the housing and fitting on the cam shaft parts of respective ones of the hinge shafts so as not to rotate with respect to the housing, each of the movable members having a second cam, to engage with a respective one of the first cams;
• and
• plural compression springs disposed in the respective ends of the housing to bias the plural movable members toward the plural first cams, respectively.

A hinge device to rotatably couple a door to a main body, comprising:

• a housing mounted on any one of the door and the main body;
• plural hinge shafts rotatably fitting in respective ends of the housing, each of the hinge shafts including a first cam unit thereon with an extension shaft part to couple to a remaining one of the door and the main body;
• plural movable members, received in the respective ends of the housing and coupling to a cam unit of a respective one of the hinge shafts so as to allow the movable members to longitudinally move while preventing a rotation of the movable members with respect to the housing, each of the movable members having a second cam unit to engage with a respective first cam unit;
• and
• plural compression units disposed adjacent to the movable member, to bias the plural movable members toward respective first cams, respectively.

A storage container, comprising:

• a container body having a storage chamber with a top thereof being opened;
• a door to close the container body;
• and
• a hinge device to enable the door to rotatably couple to the container body, wherein the hinge device comprises:
• a housing mounted on any one of the door and the main body;
• plural hinge shafts rotatably fitting in respective ends of the housing, each of the hinge shafts including a cam shaft part with a first cam provided thereon, and a respective extension shaft part extending from the cam shaft part to couple to a remaining one of the door and the container body;
• plural movable members, received in the respective ends of the housing and fitting on the cam shaft parts of respective ones of the hinge shafts so as not to rotate with respect to the housing, each of the movable members having a second cam to engage with a respective one of the first cams;
• and
• plural compression springs disposed in the respective ends of the housing to bias the plural movable members toward the plural first cams, respectively.
