Abstract:
1. A cabinet door buffer bar, mounted onto a cabinet having a pivot axle between a cabinet door and a cabinet wall, the cabinet door buffer bar providing a buffer for the cabinet door during closing, comprising: a hollow tube mounted onto the cabinet door or the cabinet wall, and abutting one of the cabinet door and the cabinet wall, said hollow tube having a housing compartment; a shaft movably located in the housing compartment, the shaft having a tongue on a rear end thereof exposed outside the hollow tube, the shaft having a front end with a diameter smaller than a rear end, the shaft being adjacent an inner wall of the hollow tube, differences in diameter of the shaft forming a gap with portions of different dimensions between the shaft and the inner wall of the hollow tube in the axial direction of the shaft; an elastic element located in the hollow tube pressing the shaft to expose the tongue outside the hollow tube in normal conditions; and a resilient member connected to the front end of the shaft, the resilient member having a portion in contact with the inner wall of the hollow tube; wherein when pushing the tongue of the shaft, inwards the resilient member generates greater friction with the inner wall than when the tongue is moved outwards due to the resilient member being moved toward the smaller gap between the shaft and the inner wall of the hollow tube during pushing of the tongue and being moved away from the smaller gap when the tongue is moved outwards whereby, a greater buffer force is provided during pushing of the tongue than during outward movement of the tongue.
