Title: A preventing separation structure for socks with hide type module
Inventor: CHOI SEUNG OUG
IPC: D06F95/00
Filed: 2021-03-17
Abstract: The present invention has a structure in which female and male snap buttons are supported so as to be covered by left and right concealed modules each fixed to one side of two socks. When socks are not worn, each of the female and male snap buttons is exposed to the outside by an opening operation of the concealed module, so that the two socks can be combined to match each other so as to form a pair in washing, drying, and storage. When wearing socks, the male and female snap buttons can be covered not to be exposed to the outside by a closing operation of the concealed module made of silicon. Therefore, it is possible to prevent a T-shaped protruding part formed on the female and male snap buttons from contacting the opposite ankle skin and clothing in advance. In particular, it is possible to increase marketability by preventing abrasion which can occur when the T-shaped protruding part formed on the female and male snap buttons comes into contact with the skin and lint which can be caused by contact with clothing, and preventing aesthetic appearance of the socks from being impaired.
