The present disclosure relates to a safety storage furniture, and an object of the present disclosure is to provide safety storage furniture, in which a locking unit having a locking groove provided on one side surface of a drawer and a guide unit having an inclined guide and a horizontal guide are integrally connected and installed, such that an assembly property of the storage furniture may be improved and extended and locked states of the drawer may be smoothly maintained.

A bidirectional drawer system is disclosed. The bidirectional drawer system can include a frame. The bidirectional drawer system can also include first and second drawers slidably coupled to the frame. Each of the first and second drawers can be movable between a retracted position and first and second extended positions on opposite sides of the retracted position. In addition, the bidirectional drawer system can include a drawer interlock mechanism. The drawer interlock mechanism can include first and second interlock portions associated with the first and second drawers, respectively. The first interlock portion can have a cam with a cam surface, and a cam follower operable to interface with the cam surface. The second interlock portion can have a cam lock with a cam lock surface, and cam follower operable to interface with the cam lock surface. With the first and second drawers in the retracted positions, movement of the first drawer toward the first extended position can cause the cam follower of the first interlock portion to engage the cam surface and the cam follower of the second interlock portion to engage the cam lock surface thereby preventing movement of the second drawer out of the retracted position.

A refrigerator includes a cabinet that defines a storage chamber, an upper door that is configured to open and close an upper portion of the storage chamber by being drawn in and out, a lower door that is positioned below the upper door and that is configured to open and close a lower portion of the storage chamber by being drawn in and out, an upper door restriction unit that is configured to selectively restrict the upper door from being opened, and a lower door restriction unit that is configured to selectively restrict the lower door from being opened. The upper door restriction unit is configured, based on the lower door being opened, to restrict the upper door from opening, and the lower door restriction unit is configured, based on the upper door being opened, to restrict the lower door from opening.

A refrigerator and a control method therefor are provided. When a user input is received, an upper drawer of the refrigerator is opened by operating an opening/closing motor of the upper drawer, and it is determined whether opening of a lower drawer is detected by an open/close detecting part of the lower drawer when the upper drawer is opened. The lower drawer is closed by operating the opening/closing motor of the lower drawer when the opening of the lower drawer is detected.

The present invention provides an interactive drawer-fastening mechanism, comprising a driving shaft component and a fastening assembly; the driving shaft component including a seat and a driving arm; the fastening assembly including a fastening base, an upper limit block, a lower limit block, and a plurality of sliding block components, the sliding block component including a sliding block, a retaining shaft and a torsion spring, the retaining shaft including an arc plate, an immovable shaft and a movable shaft, wherein the retaining shaft has the immovable shaft. The present invention has the fastening assembly and the driving shaft component as separate modules, and has the slide guide working with the lock component to realize the interactively fastening mechanism. The modularized design on one hand structurally simplifies the fastening mechanism and allows easy installation, and on the other hand effectively enhances the reliability of both interaction and fastening.
