Typically, storage closets for storing various items are installed in bathrooms, laundry rooms, and utility rooms.

Known domestically as a conventional bathroom storage cabinet installed in the bathroom, registered utility model No. 20-0380769 (bathroom storage cabinet), registered utility model No. 20-0410168 (sliding door opening and closing structure of bathroom storage cabinet), open utility model New plan No. 20-2014-0006032 (sliding door for decoration using a slider), registered patent No. 10-1240370 (round sliding bathroom cabinet), registered patent No. 10-1249704 (opening and closing device for sliding door for bathroom cabinet), registered Patent No. 10-1867038 (bathroom storage cabinet with sliding door) is known.

These bathroom storage cabinets use upper and lower plates, side plates, and back plates to form a rectangular storage cabinet with an open front, and a pair of opening and closing doors (front sliding door, rear sliding door) on the front of the rectangular-shaped storage cabinet. It was installed so that it can slide left and right.

A pair of sliding doors (front sliding door and rear sliding door) installed on the front of these storage cabinets are equipped with frame corner connection devices in which roller brackets are integrated into frame connection brackets at four corners, and each frame corner The horizontal and vertical joints formed horizontally or vertically in the frame connection bracket of the connection device are designed to maintain a right angle by combining the horizontal frame and the vertical frame.

However, these frame edge connecting devices have the problem of poor workability because they cannot easily connect the roller bracket to the frame connection bracket.

Proposals to somewhat solve this problem include Registered Patent No. 10-1344636 (Roller device for sliding doors with improved assemblage) and Registered Patent No. 10-1936419 (Sliding door frame connector and device including the same). Storage cabinet) and Registered Patent No. 10-2115975 (connection structure of sliding door frame) are known.

In the above registered patent No. 10-1344636 (roller device of a sliding door with improved assemblage), a roller bracket is coupled to one side (back) of an edge coupling bracket formed in an 'ㄱ' shape, and the front of the corner coupling bracket is A fixing protrusion having a locking protrusion and fastening protrusions with fastening holes are formed to be spaced apart vertically, and fastening holes and fastening long holes are formed to be spaced up and down on the fixing plate of the roller bracket, and the fixing protrusions and fastening protrusions are coupled to the fastening holes and fastening long holes. In this state, the fastening bolt is screwed to the fastening stone piece through the fastening hole, and the corner coupling bracket and roller bracket are integrated into one piece.

However, since the fixing protrusion and the fastening stone piece are combined with the fastening hole and the fastening long hole, the fastening bolt is screwed to the fastening stone piece through the fastening long hole, so the corner connecting bracket and roller bracket can be modularized in one piece, but the workability (assembly efficiency) is low. It falls.

Registration Patent No. 10-1936419 (sliding door frame connecting device and storage cabinet including the same) has a placement groove and a slide groove formed vertically and horizontally on the inner surface of the connection body forming the frame connection bracket, and the placement groove has a roller bracket. The frame insertion part is combined, the slide body is elastically loaded into the slide groove by a pressurized elastic member (coil spring), and the seating groove formed on the inside of the arrangement groove is loaded with a leaf spring as a close elastic member.

However, since the frame insertion part of the roller bracket is coupled to the arrangement groove of the connection body from the front, there is a door that cannot detain the frame insertion part of the roller bracket in the arrangement groove of the connection body, and the frame insertion part of the roller bracket coupled to the arrangement groove is Since the adhesive elastic member (leaf spring) loaded in the seating groove is ejected to the outside, there is a disadvantage in that the frame connection bracket and roller bracket cannot be assembled and stored in a modular form. Therefore, the frame connection bracket and roller bracket cannot be stored in a modular form at the site where the sliding door frame is assembled. It must be installed while assembling the connection bracket and roller bracket, which ultimately reduces the assembly efficiency of the sliding door frame.

Registered Patent No. 10-2115975 (connection structure of a sliding door frame) involves inserting and loading the insertion piece of a roller bracket vertically into the insertion hole of the body forming the frame connection bracket, and inserting the insertion piece of the roller bracket vertically into the insertion hole of the body forming the frame connection bracket. A moving bar is installed elastically by a spring piece on the front plate and the horizontal connecting piece of the body, and is installed by engaging a fixing pin formed on one end of the spring piece with a fixing groove formed on the outer end of the loading groove on the horizontal connecting piece.

However, this causes a phenomenon in which one piece of the spring piece (fixing pin) is separated from the fixing groove of the loading groove, and as a result, the moving bar does not receive the elastic force of the spring piece and loses its function, which ultimately causes the roller bracket to be detained in the frame connection bracket. If this is not possible, these roller brackets and frame connection brackets cannot be modularized, and therefore, they must be installed while assembling the roller brackets and frame connection brackets at the site where the sliding door frame is assembled, which ultimately reduces the assembly efficiency of the sliding door frame.
