Slide rail kit

1 . A slide rail kit applicable to a rack, the slide rail kit comprising:

a first rail comprising a first wall, a second wall and a side wall connected between the first wall and the second wall, wherein a bracket is attached to the first rail, a mounting feature is arranged on the bracket, and the side wall has an inner side and an outer side facing toward the rack, wherein the bracket comprises a first edge part, a second edge part and a side part connected between the first edge part and the second edge part, the side part of the bracket is fixed to the outer side of the side wall of the first rail, and the first edge part and the second edge part of the bracket are configured to respectively hold the first wall and the second wall of the first rail; and

a locking member movably mounted to the side part of the bracket on the first rail and comprising a locking part and an operating part, wherein the side wall of the first rail is formed with a predetermined hole communicating the outer side and the inner side of the side wall, and the predetermined hole at least corresponds to the operating part of the locking member;

wherein the mounting feature is configured to mount the first rail to a mounting structure of the rack;

wherein the locking part is configured to be held at the outer side of the side wall of the first rail to be blocked by the rack in response to an elastic force of an elastic structure;

wherein the operating part is configured to be operated to move the locking part toward the inner side of the side wall of the first rail, such that the locking part is no longer blocked by the rack.

2 . The slide rail kit of claim 1 , wherein the mounting structure of the rack is a mounting hole, and the mounting feature is configured to be mounted to the mounting hole and blocked by a hole wall of the mounting hole to prevent the first rail from being moved relative to the rack along a first predetermined direction.

3 . The slide rail kit of claim 2 , wherein when the locking part is blocked by the rack, the locking part is configured to prevent the first rail from being moved relative to the rack along a second predetermined direction different from the first predetermined direction.

4 . The slide rail kit of claim 1 , wherein the locking member is pivotally connected to the side part of the bracket on the first rail through a shaft member to be rotatable relative to the bracket.

5 . The slide rail kit of claim 4 , wherein the elastic structure comprises a first elastic section and a second elastic section, the first elastic section is configured to contact one of the bracket and the first rail, and the second elastic section is configured to contact the locking member.

6 . The slide rail kit of claim 1 , wherein the first rail has a first end part and a second end part opposite to each other, and the locking member is located adjacent to the first end part of the first rail.

7 . The slide rail kit of claim 1 , wherein a passage is defined by the first wall, the second wall and the side wall; wherein the slide rail kit further comprises a second rail movably mounted in the passage of the first rail, and the second rail is located at the inner side of the side wall of the first rail; wherein when the second rail is located at a retracted position relative to the first rail, the second rail does not cover the operating part.

8 . The slide rail kit of claim 7 , further comprising at least one first slide assisting device mounted between the first rail and the second rail and configured to assist relative movement between the first rail and the second rail.

9 . The slide rail kit of claim 8 , further comprising a third rail movably mounted to the second rail, and a second slide assisting device mounted between the second rail and the third rail and configured to assist relative movement between the second rail and the third rail.

10 . The slide rail kit of claim 1 , wherein a passage is defined by the first wall, the second wall and the side wall; wherein the slide rail kit further comprises a second rail movably mounted in the passage of the first rail, and the second rail is located at an inner side of the side wall of the first rail.

11 . A slide rail kit applicable to a rack, the slide rail kit comprising:

a first rail comprising a first wall, a second wall and a side wall connected between the first wall and the second wall, a passage being defined by the first wall, the second wall and the side wall, the side wall having an inner side and an outer side facing toward the rack, wherein a bracket is attached to the first rail, a mounting feature is arranged on the bracket, the bracket comprises a first edge part, a second edge part and a side part connected between the first edge part and the second edge part, the side part of the bracket is fixed to the outer side of the side wall of the first rail, and the first edge part and the second edge part of the bracket are configured to respectively hold the first wall and the second wall of the first rail;

a second rail movably mounted in the passage of the first rail; and

a locking member movably mounted to the side part of the bracket on the first rail and comprising a locking part and an operating part, wherein the side wall of the first rail is formed with a predetermined hole communicating the outer side and the inner side of the side wall, and the predetermined hole at least corresponds to the operating part of the locking member;

wherein the mounting feature is configured to mount the first rail to a mounting structure of the rack;

wherein the locking member is configured to be held in a state being blocked by the rack in response to an elastic force of an elastic structure;

wherein the operating part is configured to be operated to move the locking part away from the state being blocked by the rack;

wherein the second rail is located at the inner side of the side wall of the first rail; when the second rail is located at a retracted position relative to the first rail, the second rail does not cover the operating part.

12 . The slide rail kit of claim 11 , wherein the mounting structure of the rack is a mounting hole, and the mounting feature is configured to be mounted to the mounting hole and blocked by a hole wall of the mounting hole to prevent the first rail from being moved relative to the rack along a first predetermined direction; wherein when the locking part is in the state being blocked by the rack, the locking part is configured to prevent the first rail from being moved relative to the rack along a second predetermined direction opposite to the first predetermined direction.
