Publication number: 20220192376Abstract: A slide rail assembly and a slide rail kit are provided. The slide rail assembly includes a first rail, a second rail, a blocking member, and an operating member. The blocking member is movably mounted on the second rail. When the second rail is positioned at an extending position relative to the first rail, a blocking feature of the first rail blocks the blocking member at a first state, so as to prevent the second rail from being moved from the extending position in a retracting direction. The operating member is operated to be positioned at a position that moves the blocking member from the first state to a second state, such that the blocking feature is unable to block the blocking member at the second state. The operating member is engaged with the predetermined portion of the second rail to be retained at the position.Type: ApplicationFiled: June 15, 2021Publication date: June 23, 2022Applicants: KING SLIDE WORKS CO., LTD., KING SLIDE TECHNOLOGY CO.,LTD.Inventors: Ken-Ching Chen, Shun-Ho Yang, Wei-Chen Chang, Chun-Chiang Wang
