And due to the elastic force applied by the elastic member 34 in the first direction D1, the second projection 58 of the movable member 36 presses the contact portion 90 against the stop wall 48.
  • the deceleration spring 66 of the deceleration mechanism 16 applies to the supporting member 64 an elastic force in a second direction D2, wherein the elastic force in the second direction D2 acts in a different direction from the elastic force in the first direction D1 (e.g., the second direction D2 being opposite the first direction D1).
  • the elastic force applied by the elastic member 34 in the first direction D1 is greater than the elastic force applied by the deceleration spring 66 in the second direction D2. This ensures that the second rail 12 will stay in the retracted position once fully retracted relative to the first rail 10.

  • the actuating portion 60 of the movable member 36 is guided by the guide portion 22 of the second rail 12 and eventually engages with the stop portion 24 such that the second projection 58 of the movable member 36 is no longer engaged with the engaging portion 46.
  • the first projection 56 of the movable member 36 is subjected to the elastic force released by the elastic member 34 in the first direction D1
  • the movable member 36 is automatically displaced toward the retracted position in response to the elastic force of the elastic member 34.
  • the second rail 12, therefore, is driven by the actuating portion 60 of the movable member 36 and moved automatically toward the retracted position (see FIG. 9A and FIG. 9B ).
  • the second projection 58 of the movable member 36 pushes at least one portion (e.g., the contact portion 90) of the supporting member 64 and thereby displaces the supporting member 64 in the first direction D1 along with the movable member 36.
  • the elastic force provided by the elastic member 34 in the first direction D1 must be able to overcome the elastic force provided by the deceleration spring 66 and acting on the supporting member 64 in the second direction D2 (i.e., the elastic force provided by the deceleration spring 66 can be viewed as resistance against the elastic member 34 and serves to counteract the elastic force of the elastic member 34) in order for the movable member 36 to be displaced along the longitudinal portion 44 in the first direction D1 at a reduced speed and thus automatically and slowly moves the second rail 12 back to the retracted position after the second projection 58 of the movable member 36 leaves the engaging portion 46.
  • the friction portion 84 of the supporting member 64 provides further resistance as it is displaced relative to the damping room 76 in the first direction D1, thanks to the friction surface 80 in the damping room 76 or the friction surface 94 of the friction portion 84.
  • This additional resistance lowers the speed at which the second projection 58 of the movable member 36 is displaced from the engaging portion 46 to the longitudinal portion 44, allowing the movable member 36 to move the second rail 12 back to the retracted position slowly as well as automatically.
  • the cushioning medium 97 in the damping room 76 can effectively decelerate displacement of the friction portion 84 relative to the damping room 76 in the first direction D 1 and reduce the sound generated by direct impact between an end portion of the friction portion 84 of the supporting member 64 and the inner wall of the damping room 76.

  • the deceleration force provided by the deceleration mechanism e.g., the resistance provided by the deceleration spring 66 and the additional resistance provided by the friction surface 80 or the friction surface 94
  • the deceleration force provided by the deceleration mechanism is less than the elastic force provided by the elastic member 34 of the self-closing mechanism, in order for the movable member 36 to move the second rail 12 back to the retracted position both automatically and slowly, allowing the second rail 12 to decelerate when it has been pushed relative to the first rail 10 to a position adjacent to the last part of its retracting course.
  • FIG. 14 shows the second embodiment of the self-closing slide rail assembly with a deceleration mechanism according to the present invention.
  • the second embodiment is different from the first embodiment generally in that the base 200 includes a first longitudinal section 202 and a supporting portion 204 extending transversely from the first longitudinal section 202 (i.e., the base 200 lacks the second longitudinal section 70 in the first embodiment).

Meanwhile, the deceleration spring 306 releases the elastic force in the second direction D2, and the supporting member 308 is therefore retained at a certain position (see FIG.
  • the actuating portion 316 of the movable portion 312 will engage with the second rail (e.g., by means of the stop portion 24 in a way similar to that shown in FIG. 13A ), causing the movable member 312 to disengage from the engaging portion 314, and the elastic member 318 to release an elastic force in the first direction D1.
  • the movable member 312 which has left the engaging portion 314, will be displaced along the longitudinal portion 320 in the first direction D1 and thus automatically and slowly move the second rail back to the retracted position.
  • the deceleration spring 306 applies to the supporting member 308 an elastic force in the second direction D2, and when the movable member 312 is pressed against the contact portion 322 of the supporting member 308 by the elastic force applied by the elastic member 318 in the first direction D1, the elastic force applied by the deceleration spring 306 serves as resistance against the elastic force applied by the elastic member 318.
  • the friction surface in the damping room, the friction surface of the friction portion, and the cushioning medium filled in the damping room provide further deceleration when the second rail has been pushed relative to the first rail 300 into the last part of its retracting course.
  • This additional deceleration effect has been disclosed in the first embodiment (with reference to FIG. 13B , FIG. 8A and FIG. 8B ) and, for the sake of simplicity, will not be explained repeatedly herein.
  • FIG. 17 shows the fourth embodiment of the present invention.
  • the fourth embodiment is different from the first embodiment generally in that: the base 402 of the deceleration mechanism has a friction portion 404; the friction portion 404 has a friction surface 406 and a rib 408 opposite the friction surface 406; the supporting member 410 is movably connected with the friction portion 404; the supporting member 410 at least includes a first wall 412a, a second wall 412b, and a bottom wall 412c extending between the first wall 412a and the second wall 412b; and the first wall 412a, the second wall 412b, and the bottom wall 412c define a damping room 414 corresponding to the friction portion 404.
  • the first wall 412a of the supporting member 410 includes a friction surface 416 located in the damping room 414 and corresponding to the friction surface 406 of the friction portion 404 (e.g., the friction surfaces 416 and 406 being corresponding serrated surfaces).
  • the second wall 412b of the supporting member 410 includes a groove 418 corresponding to the rib 408 of the friction portion 404.
  • the damping room 414 can also be filled with a cushioning medium (the principle of which can be understood with reference to FIG. 8B and will not be stated repeatedly herein).
  • the base 402 of the deceleration mechanism further includes at least one portion 420.
  • the deceleration spring 422 is longitudinally connected between the at least one portion 420 and a portion (e.g., a rear portion 423) of the supporting member 410.
  • the deceleration spring 422 applies to the supporting member 410 an elastic force in the second direction D2 such that the supporting member 410 is retained at a certain position in response to the elastic force applied by the deceleration spring 422. If, in this state, the second rail (now shown) is retracted in the first direction D1 toward a retracted position relative to the first rail 428, the actuating portion 430 of the movable member 424 will engage with the second rail (e.g., by means of the stop portion 24 in a way similar to that shown in FIG.
  • the deceleration spring 422 applies to the supporting member 410 an elastic force in the second direction D2, and when the movable member 424 is pressed against the contact portion 436 of the supporting member 410 by the elastic force applied by the elastic member 432 in the first direction D1, the elastic force applied by the deceleration spring 422 serves as resistance against the elastic force applied by the elastic member 432.
  • the movable member 424 therefore, is equally capable of moving the second rail back to the retracted position automatically and slowly.
  • the supporting member 410 when driven by the movable member 424, is displaced relative to the friction portion 404 and provides resistance through the friction surface 416 in the damping room 414 and the friction surface 406 of the friction portion 404.
  • the cushioning medium filled in the damping room 414 can provide further deceleration when the second rail has been pushed relative to the first rail 428 into the last part of its retracting course.
