Description

Technical Field

[0001] This utility model relates to the field of drawer technology, and in particular to a drawer slide assembly with synchronous sliding opening and closing upon pressing. Background Technology

[0002] Chinese Patent Document No. CN111642918B, published on February 7, 2025, discloses a labor-saving, silent, press-and-rebound opening and closing device for furniture, including a rebound bracket, a pushing element, and a pressing element. The rebound bracket has a U-shaped groove, and the pushing element has a sliding shaft. The pressing element elastically extends and slides on the pushing element and / or the rebound bracket, and during sliding, it acts to drive the sliding shaft to be positioned and / or slide along the trajectory of the U-shaped groove in a sequential direction. It also includes a lever assembly, which has a lever action part, and the pushing element has a pushing action part. The U-shaped groove has at least an upper limit sliding area, a conversion area, and a front stopping area. When the sliding shaft slides on the upper limit sliding area, it acts to drive the pressing element and the pushing element to slide out of the rebound bracket. When the sliding shaft slides on the upper limit sliding area to a certain position, it disengages from the pressing element. When the sliding shaft and the pressing element disengage, the pushing element interacts with the lever action part through the pushing action part. This push-to-open mechanism is applied to drawers. It is located between the moving and fixed rails. When the drawer is closed, pressing the drawer panel will cause the drawer to pop out via the mechanism. Since there are two moving and fixed rails, there are also two push-to-open mechanisms. However, there is no synchronization mechanism between the two mechanisms. When the left or right side of the drawer panel is pressed (i.e., when the user is not pressing in the middle of the drawer panel), the two mechanisms cannot move synchronously, causing the drawer to tilt and pop out. Therefore, the drawer cannot be fully opened onto the cabinet, requiring the user to manually pull it out to open it completely.

[0003] Therefore, further improvements are necessary. Utility Model Content

When one of the pressing and rebound opening and closing mechanisms 3 is unlocked, the pushing element 5, the pressing element 6 and the transmission piece 7 of the two pressing and rebound opening and closing mechanisms 3 are synchronously moved through the synchronization rod 28, so that the two movable rails 1 of the drawer are synchronously and elastically slid and opened on the fixed rail 2.

[0050] The fixed rail 2 is fixed on the cabinet body. The drawer comprises a panel. When a user presses at any position of the panel, the two pressing and rebound opening and closing mechanisms 3 are triggered to be synchronously unlocked, which is very sensitive.

The other gear is driven to rotate through the rotation of the synchronization rod 28. The other transmission piece 7 is driven to move through the rotation of the other gear. Then, the other pushing element 5 and the other transmission piece 7 are unlocked. When the pushing element 5 and the transmission piece 7 move to the corresponding positions, the transmission pieces 7 on the two movable rails 1 are synchronously and elastically reset.

[0053] Through the increase of the elastic force of the first elastic piece 13, it can be ensured that the drawer is completely opened on the cabinet body, or after the two movable rails 1 of the drawer are synchronously slid out by a distance, the user can pull out the drawer by hand.

The drawer slide assembly with synchronous sliding opening and closing upon pressing according to claim 5, characterized in that: A movable part (21) is provided on the moving rail (1), and a rear area sliding guide part (22) is provided on the pressing element (6); when the moving rail (1) slides closed on the fixed rail (2), it drives the pressing element (6) and the movable part (21) to move in the direction of the transmission member (7). When the movable part (21) moves in the direction of the transmission member (7), it drives the lever assembly (29) to rotate on the rebound bracket (4). The lever action part (17) and the pushing action part (18) interact to drive the pushing element (29). 5) Move towards the transmission member (7), the sliding shaft part (10) slides from the front stopping area (20) to the lower limit sliding area (12). When the sliding shaft part (10) slides to the corresponding position on the lower limit sliding area (12), it interacts with the rear area sliding guide part (22) and drives the pushing element (5) to continue moving towards the transmission member (7). When the pushing action part (18) acts on the sliding shaft part (10) and the rear area sliding guide part (22), it disengages from the lever action part (17).

7. The drawer slide assembly with synchronous sliding opening and closing upon pressing according to claim 6, characterized in that: When the pressing element (6) moves toward the transmission element (7), it slides into the rebound bracket (4), and the pressing element (6) acts through the rear area sliding guide (22) and drives the sliding shaft (10) to slide obliquely from the lower limit sliding area (12) and be positioned on the locking position (16). When the sliding shaft (10) is positioned in the locking position (16), it disengages from the rear area sliding guide (22). When the pressing element (6) is positioned in the locking position (16) of the sliding shaft (10), it extends into the rebound bracket (4). The pressing element (6) is also provided with a rear area sliding guide (23); the pressing element (6) interacts with or disengages from the sliding shaft (10) through the rear area sliding guide (23). When the sliding shaft (10) is positioned in the locking position (16) and the pressing element (6) is pressed and slid relative to the rebound bracket (4), the pressing element (6) acts through the rear area sliding guide (23) and drives the sliding shaft (10) to tilt and slide out from the locking position (16) to the unlocking sliding area (32). The pressing element (6) is also provided with a pressing action part (24). When the sliding shaft part (10) slides in the upper limit sliding area (11), it acts on the pressing action part (24) to drive the pressing element (6) to slide out of the rebound bracket (4). When the sliding shaft part (10) slides to the corresponding position in the upper limit sliding area (11), it disengages from the pressing action part (24).

8. The drawer slide assembly with synchronous sliding opening and closing upon pressing according to claim 4, characterized in that: A limiting part (25) is provided on the pressing element (6), and a limiting mating part (26) is provided on the pushing element (5). A third elastic element (27) is also provided between the pressing element (6) and the pushing element (5). One end of the third elastic element (27) is elastically connected to the pressing element (6), and the other end is elastically connected to the pushing element (5). The pressing element (6) is always elastically extended and slid in the direction of the locking position (16) on the limiting mating part (26) of the pushing element (5) through the cooperation of the limiting part (25) and the third elastic element (27). The elastic force of the first elastic element (13) is greater than the elastic force of the third elastic element (27).

9. The drawer slide assembly with synchronous sliding opening and closing upon pressing according to claim 1, characterized in that: The synchronization device (8) includes a synchronization rod (28) that is connected to the transmission component (7). A drawer is provided on the moving rail (1). The drawer is supported on two moving rails (1). The press-and-rebound opening and closing mechanism (3) on each moving rail (1) is connected to the synchronization rod (28). When one of the press-and-rebound opening and closing mechanisms (3) is unlocked, the pushing element (5), pressing element (6), and transmission component (7) of the two press-and-rebound opening and closing mechanisms (3) move synchronously through the synchronization rod (28) so that the two moving rails (1) of the drawer slide open synchronously on the fixed rail (2).

10. The drawer slide assembly with push-to-open and push-to-close synchronous opening and closing as described in claim 9, characterized in that: The transmission component (7) is provided with a first joint (30), and the synchronizing rod (28) is provided with a second joint (31). The transmission component (7) and the synchronizing rod (28) are connected by the cooperation of the first joint (30) and the second joint (31).
