The first base 46 responds to the displacement of the first rail 28 in the second direction D2 and can drive the control member 106 to swing from the locked state L1 to the unlocked state L2 (with respect to the displacement of the control member 106 from the locked state L1 The process to the unlocked state L2 can be referred to FIG. 13, FIG. 14 and FIG. In this state, the first member 84 cannot move in the second direction D2 relative to the auxiliary track 36 (that is, the first member 84 cannot move in the second direction D2 relative to the second furniture piece 24 ). In other words, in this state, the first member 84 can only move in the above-mentioned first direction D1 (ie a direction opposite to the second direction D2 ) on the auxiliary track 36 .

As shown in Fig. 22, Fig. 23 and Fig. 24, when the control part 106 is in the unlocked state L2 (that is, the guide part 116 of the control part 106 is located in the first path 112 of the control path 110), and once released When an external force is applied in the second direction D2, the first elastic member 50 releases the first elastic force in the first direction D1 and can drive the first rail 28 from the above-mentioned retracted position P1 relative to the second rail 30. The first direction D1 is displaced. In other words, when the control member 106 of the first lock device 54 is in the unlocked state L2, the first lock device 54 unlocks the first elastic member 50, so that the first elastic member 50 can release the first elastic member 50. The elastic force causes the first base 46 and the second base 48 to displace along with the first rail 28 in the first direction D1. In short, the first rail 28 can be opened relative to the second rail 30 in the first direction D1 in response to the release of the first elastic force of the first elastic member 50 . Wherein, when the second base 48 is displaced in the first direction D1, the guide path 72 of the second base 48 is displaced relative to the catcher 68, so that the first foot 71 of the catcher 68 moves from the guide Longitudinal path 74 of path 72 enters into transverse path 76 . Accordingly, the catcher 68 can be deflected at an angle relative to the stopper 70 , so that the catch feature 118 of the catcher 68 disengages from the locking feature 38 on the extension seat 34 . In addition, the buffer rod 82 of the buffer device 78 protrudes relative to the cylinder 80 to be in a buffer ready state and can correspond to the stopper 70 of the second lock device 56 .

As shown in Figure 25, Figure 26 and Figure 27, when the first rail 28 receives an external force and moves from an open position P2 relative to the second rail 30 to the second direction D2 (also can be regarded as the first The furniture part 22 receives an external force and moves from an open position P2 relative to the second furniture part 24 to the second direction D2), the first base 46 and the second base 48 follow the first rail 28 to the The second direction D2 is displaced. Wherein, based on that the first lock device 54 is in a locked state (for example, the above-mentioned locking member 96 in FIG. between), and the control portion 108 of the control member 106 engages the engaging section 94 of the second member 86 , so that the above-mentioned first member 84 cannot be displaced in the second direction D2 on the auxiliary track 36 . In this state, the first elastic member 50 can store a first elastic force in response to the external force, and the second elastic member 52 can also store a second elastic force in response to the external force. Specifically, when the first base 46 is displaced relative to the second rail 30 in response to the external force, the first elastic member 50 is stretched by the first base 46 to accumulate elastic force; on the other hand, the second elastic For the member 52 , because the first leg 71 of the catching member 68 is locked against the transverse path 76 of the guiding path 72 , the second elastic member 52 is stretched by the second base 48 to store elastic force.

As shown in FIGS. 28 and 29 , when the first rail 28 is displaced relative to the second rail 30 from the open position P2 to the second direction D2 toward the retracted position P1 to a predetermined distance (for example, the first rail 28 When the longitudinal distance X) of the first path 112 of the above-mentioned control path 110 is displaced, the first base 46 is displaced to allow the control member 106 to return to the second path 114 from the first path 112 of the control path 110, the The control member 106 can return to the locked state L1 again from the above-mentioned unlocked state L2 relative to the second member 86, so that the control portion 108 of the control member 106 cannot engage the locking section 94 of the second member 86. In this state Next, the first elastic member 50 and the second elastic member 52 can maintain a first elastic force (first driving force) and a second elastic force (second driving force) respectively. In other words, the control member 106 of the first locking device 54 can return to the state of locking the first elastic member 50 in response to the displacement of the first rail 28 relative to the second rail 30 to the predetermined distance. Wherein, the second elastic force of the second elastic member 52 can face the second direction D2, and the second elastic force can act on the connecting member 44 . On the other hand, the catch 68 is about to catch the detent feature 38 of the second rail 30 .

As shown in FIGS. 30 and 31 , when the first rail 28 is further retracted toward the second direction D2 relative to the second rail 30 (for example, the final stroke), the catching feature 118 of the catching member 68 catches The locking feature 38 of the second rail 30 makes the first foot 71 of the catcher 68 disengage from the transverse path 76 of the guide path 72 and move to the longitudinal path 74, that is, the catcher 68 is biased relative to the stopper 70. Swing an angle and return to the state that is close to the stopper 70 .

As shown in FIG. 32 and FIG. 33 , when the catch member 68 catches the locking feature 38 of the second rail 30, the second elastic member 52 releases the second elastic force accordingly, so that the first rail 28 responds to the second rail 30. The elastic force displaces the second rail 30 to the retracted position P1 in the second direction D2. In other words, the first furniture part 22 can be displaced from the open position P2 to the retracted position P1 relative to the second furniture part 24 along the second direction D2 in response to the second elastic force. In addition, by means of the buffer bar 82 of the buffer device 78 abutting against the stopper 70 , the first rail 28 can have a buffering effect when the first rail 28 is retracted relative to the second rail 30 to the retracted position P1 .

It is worth mentioning that the present invention also provides a driving method for the above-mentioned first furniture piece 22 and the second furniture piece 24. Since the driving method has been disclosed in the above-mentioned embodiment, for the sake of brevity, it will not be described here. Let me repeat.

According to the above description, it can be seen that the enhanced efficacy and advantages of the present invention are: when the furniture component can be displaced from any open position to a predetermined distance, the furniture component can be driven to the retracted position through the driving mechanism.
