A third blocking protrusion 225 protrudes from the second main plate 22 to an outer side of the second main plate 22. The third blocking protrusion 225 is located in front of the second blocking protrusion 223. The second blocking protrusion 223 and the third blocking protrusion 225 are located at a rear portion of the intermediate slide 20. A second opening 227 is defined in the second main plate 22 and located adjacent to a front end of the intermediate slide 20.
[0018] The inner slide 30 includes a third main plate 32 and pair of third flanges 321 extending from upper and lower lengthwise edges of the third main plate 32. Each of the pair of third flanges 321 includes a horizontal part 3211 extending substantially perpendicularly from the upper or lower lengthwise edge of the third main plate 32, a vertical part 3213 extending substantially perpendicularly from the horizontal part 3211, and an overlapping part 3215 extending from the vertical part 3213 and abutting the vertical part 3213. A pair of second mounting posts 323 protrudes substantially perpendicularly from an outer side of the third main plate 32. A fourth blocking protrusion 325 protrudes from the third main plate 32 to the outer side of the inner slide 30. The pair of second mounting posts 323 is located at a central portion of the inner slide 30. The fourth blocking protrusion 325 is located at a rear portion of the inner slide 30.
[0019] In one embodiment, the pair of first flanges 121 of the outer slide 10 is located at the inner side of the outer slide 10. The pair of second flanges 221 of the intermediate slide 20 is located at the inner side of the intermediate slide 20. The pair of third flanges 321 of the inner slide 30 is located at the outer side of the inner slide 30.
[0020] The first latch member 40 includes a first main piece 42 made from rigid resilient materials. A pair of first mounting holes 421 is defined in the first main piece 42 corresponding to the pair of first mounting posts 125. The pair of first mounting holes 421 is located at a first end of the first main piece 42. A first sloping protrusion 423 protrudes from a second end of the first main piece 42.
[0021] The second latch member 50 is similar to the first latch member 40. The second latch member 50 includes a second main piece 52 made from rigid resilient materials. A pair of second mounting holes 521 is defined in the second main piece 52 corresponding to the pair of second mounting posts 323. The pair of second mounting holes 521 is located at a first end of the second main piece 52. A second sloping protrusion 523 protrudes from a second end of the second main piece 52.
[0022] Referring to FIGS. 1 to 6, in assembly, the pair of first mounting posts 125 is engaged into the pair of first mounting holes 421. The first latch member 42 is attached to the outer side of the outer slide 10. The first sloping protrusion 423 at the second end of the first latch member 40 extends to the inner side of the outer slide 10 via the first opening 127. The second end of the first latch member 40 is aligned with a rear edge of the first opening 127. The intermediate slide 20 is slid into the outer slide 10 from the front end of the outer slide 10. The upper and lower portions with the first sections 2211 of the intermediate slide 20 is received in and slidable along the pair of first flanges 121. The third blocking protrusion abuts and presses the first sloping protrusion 423. The second end of the first latch member 40 is resiliently deformed, thereby the first sloping protrusion 423 moves to the outer side of the outer slide 10 via the first opening 127. The second end of the first latch member 40 rebounds to its original position when the third blocking protrusion 225 comes across the first sloping protrusion 423. The first sloping protrusion 423 extends to the inner side of the outer slide 10 again. The intermediate slide 20 slides into the outer slide 10 along the pair of first flanges 121 until the rear end of the intermediate slide 20 abuts the first blocking protrusion 129. Then the intermediate slide 20 slides to its retracted position. The pair of second mounting posts 323 is engaged into the pair of second mounting holes 521. The second latch member 50 is attached to the outer side of the inner slide 30. The inner slide 30 slides into the intermediate slide 20. The vertical part 3213 and the overlapping part 3215 of each third flange 321 are received in and slidable along the L-shaped second segment 2215 of each second flange 221. The inner slide 30 slides to its retracted position when the fourth blocking protrusion 325 abuts the second blocking protrusion 223. In one embodiment, after the first latch member 40 and the second latch member 50 are attached to the outer slide 10 and the inner slide 30, the first sloping protrusion 423 is slanted backward and the second sloping protrusion 523 is slanted forward.
[0023] Referring to FIG. 7, to extend the slide assembly, the intermediate slide 20 slides forward along the outer slide 10. When the third blocking protrusion 225 is slid to abut against the first sloping protrusion 423, the intermediate slide 20 slides to its extended position and cannot slide any further. The inner slide 30 slides forward along the intermediate slide 20. When the second sloping protrusion 523 reaches the second opening 227 and abuts against a front edge of the second opening 227, the inner slide 30 slides to its extended position and cannot slide any further.
[0024] In one embodiment, the particular shaped-flanges of the intermediate slide 20 and the inner slide 30 can make the slide assembly thinner, which utilizes less space in a casing.
[0025] While the present disclosure has been illustrated in detail in one or more embodiments, it is not intended to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications within the spirit and scope of the present disclosure will readily appear to those skilled in the art, and the present disclosure is not to be limited to the specific details and illustrative examples shown and described.
