Coupling mechanism and slide rail assembly for furniture part

A coupling mechanism adapted for a slide rail, the coupling mechanism comprising:

• a first base;
• a second base movably mounted on the first base;
• a coupling base configured for releasable coupling to the slide rail, the coupling base including an elastic portion deflectively biased to retentively engage a notched opening of the slide rail, the elastic portion defining a first engaging section;
• and
• a lateral adjustment member rotatably mounted on one of the first base and the second base, wherein the lateral adjustment member is configured for adjusting and thereby laterally displacing the second base with respect to the first base;
• wherein the lateral adjustment member includes an adjusting portion, and one of the first base and the second base includes a transmission structure;
• wherein the adjusting portion and the transmission structure are configured to work with each other in order to convert a rotary movement of the lateral adjustment member into a lateral displacement of the second base with respect to the first base;
• wherein the first base includes an engaging structure defining a second engaging section engageable with the first engaging section when the coupling base is deflectively biased to engage the notched opening of the slide rail;
• wherein the adjusting portion is a substantially spiral guide groove, the transmission structure is a projection located in the guide groove;
• the coupling mechanism further comprises a supporting member and a height adjustment member, wherein the supporting member includes a supporting portion, and the height adjustment member is configured for adjusting and thereby displacing the supporting member with respect to the coupling base, which is detachably fixed to the slide rail, in order to change a height of the supporting portion of the supporting member with respect to the slide rail through a guiding feature;
• the coupling base is configured for being detachably engaged with the first base, the height adjustment member is rotatably mountable on the coupling base, and the height adjustment member and the supporting member include corresponding threaded structures.

A slide rail assembly, comprising:

• a first rail;
• a second rail longitudinally displaceable with respect to the first rail;
• and
• a coupling mechanism adjacent to the second rail, wherein the coupling mechanism includes:
• a first base;
• a second base movably mounted on the first base;
• a coupling base configured for releasable coupling to the second rail, the coupling base including an elastic portion deflectively biased to retentively engage a notched opening of the second rail, the elastic portion defining a first engaging section;
• a lateral adjustment member for adjusting and thereby laterally displacing the second base with respect to the second rail;
• and
• a supporting member and a height adjustment member, the supporting member includes a supporting portion, and the height adjustment member is configured for adjusting and thereby displacing the supporting member with respect to the coupling base in order to change a height of the supporting portion of the supporting member with respect to the second rail through a guiding feature, the height adjustment member being rotatably mounted on the coupling base, and the height adjustment member and the supporting member include corresponding longitudinal threaded structures;
• wherein the first base includes an engaging structure defining a second engaging section engageable with the first engaging section when the coupling base is deflectively biased to engage the notched opening of the second rail;
• wherein when the coupling base is deflectively biased to be detachably fixed to the second rail the first engaging section of the elastic portion thereof passes through the notched opening of the second rail to detachably engage the first base.
