Description

Abutment structure of the closing device

The invention relates to an abutting structure of a closing device, in particular to an abutting structure applied to a closing device between two furniture components, which can prevent the component of the two furniture components from being damaged when the component is improperly opened. .

The "closing device for a drawers" of U. A spring is disposed between the drawer and the item of furniture. A closing device is mounted on the furniture item and includes a holding member 9 having a hook-shaped end 9' to which a latch member 11 is mounted. The fastener is a sheet-like structure having two raised areas 12, 13 wherein the raised areas 12 define a notch 14 when the drawer is in the closed position The notch of the fastener and the hook end of the holder are mutually engaged. Furthermore, the two ascending regions define at least two different guiding tracks for guiding the holder. When the drawer is displaced in opening and closing relative to the furniture item, the holder is guided by the different guiding trajectory to be bendable. When the drawer is forcibly pulled out relative to the furniture item, the holder is deformed and bent such that its hook end is forcibly released from the notch 14 of the fastener. When an external force is pushed to the closed drawer, the holding member is movable by the hook end to release the buckle, so that the drawer can be ejected back to the furniture body with the elastic force generated by the elastic member.

The foregoing patent discloses a closing device for a drawer, which is normally used by a pushing force to open the drawer. If the drawer is opened in an abnormal manner, for example, by pulling force, the bending of the holding member can be used. The hook end is forcibly detached from the notch of the fastener, but the notch 14 of the fastener is strongly frictionally contacted by the hook end of the retaining member during forced detachment, when strong After the pulling operation a few times, it is easy to wear the opposite contact of the notch with the holder, resulting in the holder being easily detached from the notch 14 of the fastener and the positioning failure.
