ABSTRACT:
A door buffering device is fastened with a top edge of a door frame and is composed of a seat, a confining member fastened in one end of a track of the seat, and a slide block fastened slidably in another end of the track of the seat such that the slide block is fastened with one end of a connection arm of a connection mechanism which is fastened with a top edge of the door. As the door is opened to the fullest extent, one end of a coil spring of the slide block collides with a rod of the confining member for mitigating the impetus of the slide block so as to minimize the door vibration.
