Description

{A Chest Of Drawers Having A Fall Prevention Structure And A Shelf Structure}

The present invention relates to a dresser shelf structure, and more specifically, to a dresser shelf structure that simultaneously includes a fall prevention structure, a shelf structure, and a chest of drawers structure.

In general, a chest of drawers is a type of storage furniture in which drawers are installed in a plurality of drawer storage spaces divided into upper and lower tiers, each with storage space for items, so that they can be entered and removed.

These drawers can store items such as clothing or toys neatly without exposing them to the outside, and are classified into wooden drawers, steel drawers, and plastic drawers depending on the material.

As shown in Figure 1, in the drawer according to the prior art, drawers are inserted in upper and lower stages in each drawer accommodation space, the height is relatively longer than the width, and the upper drawer is pulled out long as items are stored inside each drawer. There is a structural defect in the chest of drawers that causes it to tip forward when a certain amount of pressure is applied downward.

Due to these structural defects, safety accidents involving chests of drawers tipping over occur frequently in homes with children, and the number of cases in which children are seriously injured or die as a result is increasing.

Meanwhile, in order to prevent drawer accidents from falling over, the safety standards for household goods for home and office drawers were revised and came into effect on January 22, 2018. This applies to home and office drawers with a height of 762 mm or more and that the drawer must be opened when the drawer is open. The safety standard is that even if a load of about 23kg is applied downward for 1 minute, the device should not fall over.

In order to comply with the revised safety standards for chests of drawers as described above, chests of drawers currently being distributed and sold further include a fixing member for fixing the chest of drawers to the wall.

The above-mentioned fixing member is composed of fabric and nails provided at both ends of the fabric. In other words, since the fabric must be fixed to both the drawer and the wall using nails, installation is very inconvenient.

Also, when the fabric is worn, it easily separates from the nails and the holding power decreases, which also causes the dresser to easily tip over if a child hangs on the open drawer or pulls it downward.

In addition, if the wall is not flat due to the molding installed on the wall and there is a level difference due to the height difference, the fixing member must be fixed to the drawer and the wall taking into account the space between the drawer and the wall, which not only causes difficulties in installation. If fixed incorrectly, the dresser tilts backwards and cannot be properly fixed to the wall.

In addition, if the connection between the chest of drawers and the fabric is not strong, there is a structural problem that the chest of drawers easily falls over as the fixing force is easily lost by nails even under a small load applied to the chest of drawers.

Therefore, there is a need for a technology that can solve the problems caused by the prior art mentioned above.
