Slide rail mechanism and bracket device thereof

A bracket device of a slide rail mechanism, comprising:

• a supporting frame;
• a bracket, the bracket and the supporting frame being movable relative to each other, the bracket comprising a longitudinal wall and at least one mounting member adjacent to the longitudinal wall;
• a fastening member transversely movable relative to the bracket;
• and
• an elastic member configured to provide an elastic force to the fastening member;
• wherein when the supporting frame is moved relative to the bracket from a first position to a second position, the supporting frame is configured to drive the fastening member to transversely move from a first operating position to a second operating position;
• wherein when the fastening member is located at the first operating position, a fastening part of the fastening member is away from the at least one mounting member of the bracket when the fastening member is located at the second operating position, the fastening part of the fastening member is adjacent to the at least one mounting member of the bracket;
• wherein the fastening member further comprises a leg part and an arm part, the arm part is connected between the leg part and the fastening part, the supporting frame comprises a supporting structure;
• when the supporting frame is located at the first position relative to the bracket, the supporting structure does not support the leg part of the fastening member, such that the fastening member is held at the first operating position by the elastic member;
• when the supporting frame is located at the second position relative to the bracket, the supporting structure supports the leg part of the fastening member to suppress the elastic force of the elastic member, such that the fastening member is held at the second operating position.

A bracket device of a slide rail mechanism, the slide rail mechanism comprising a rail member, the bracket device comprising:

• a first supporting frame movable relative to the rail member;
• a second supporting frame movable relative to the first supporting frame;
• a bracket comprising a longitudinal wall and at least one mounting member adjacent to the longitudinal wall;
• and
• a fastening member transversely movable relative to the bracket;
• wherein the fastening member is configured to be operated to transversely move relative to the bracket between an unlocking position and a locking position;
• wherein when the fastening member is located at the unlocking position, a fastening part of the fastening member is away from the at least one mounting member of the bracket;
• wherein when the fastening member is located at the locking position, the fastening part of the fastening member is adjacent to the at least one mounting member of the bracket;
• wherein the first supporting frame and the second supporting frame are movable relative to each other through a second passage.

A slide rail mechanism, comprising:

• a rail member;
• a first supporting frame movable relative to the rail member;
• a second supporting frame movable relative to the first supporting frame;
• a first bracket, the first bracket and the second supporting frame being movable relative to each other, the first bracket comprising a longitudinal wall and at least one mounting member adjacent to the longitudinal wall;
• a fastening member;
• and
• an elastic member configured to provide an elastic force to the fastening member;
• wherein when the second supporting frame is moved relative to the first bracket along a direction from a first position to a second position, the fastening member is transversely moved relative to the first bracket from an unlocking position to a locking position;
• wherein when the fastening member is located at the unlocking position, a fastening part of the fastening member is away from the at least one mounting member of the first bracket;
• wherein when the fastening member is located at the locking position, the fastening part of the fastening member is adjacent to the at least one mounting member of the first bracket;
• wherein the fastening member further comprises a leg part and an arm part, the arm part is connected between the leg part and the fastening part, the second supporting frame comprises a supporting structure;
• when the second supporting frame is located at the first position relative to the first bracket, the supporting structure does not support the leg part of the fastening member, such that the fastening member is held at the unlocking position by the elastic member;
• when the second supporting frame is located at the second position relative to the first bracket, the supporting structure supports the leg part of the fastening member to suppress the elastic force of the elastic member, such that the fastening member is held at the locking position.
