Problems solved by technology

[0004] However, if the force of the user closing the drawer from the open position is too large or the force exerted by the person continues to push the drawer to the cabinet body without releasing the force, it may cause the drawer to move to the closed position of the cabinet body and then move again. To the over-pressure position, resulting in the drawer being opened (because of the push-to-open design), and unable to close relative to the cabinet

Embodiment Construction

[0050] Figure 1 to Figure 3 A buffer device 20 showing the first embodiment of the present invention includes a housing 22 , a piston 24 , a base 28 , a control member 30 and an elastic member 32 . Preferably, the buffer device 20 further includes an extension 26 and a spring 34 .

[0051] The housing 22 has an inner wall 38 defining a chamber 36 . The housing 22 includes a bottom 40 and a top 42 . Preferably, the bottom 40 is closed, and the top 42 has an opening 44 communicating with the chamber 36 . Wherein, the buffer device 20 further includes a cover 46 for closing the opening 44 .

[0052] The piston 24 can move linearly in the chamber 36 , specifically, the piston 24 moves substantially linearly in the chamber 36 of the housing 22 . On the other hand, the extension member 26 is movable relative to the housing 22 through the piston 24 . Specifically, one end of the extension member 26 is connected to a first side 24 a of the piston 24 , and the other end of the ex...

Description

technical field [0001] The invention relates to a furniture and its cushioning device, in particular to a cushioning device for movable furniture pieces. Background technique [0002] For example, U.S. Patent No. US 8,181,758B2 discloses that a buffer device includes a cylinder 10, which is injected with a buffer medium; an elastic member 20 is arranged in the cylinder 10; a piston 40 is movably mounted on the Inside the cylinder 10 , the piston 40 includes a piston body 42 , a connecting portion 44 connected to one end of the elastic member 20 , and a neck 46 connected between the piston body 42 and the connecting portion 44 . A control valve 60 is movably installed on the neck 46 of the piston 40 ; wherein, the movement speed of the piston 40 is controlled by the control valve 60 corresponding to the opening or closing of the opening of the piston body 42 . [0003] The buffer device disclosed in this case can be applied to a wide range of levels, such as a furniture draw...
