Description

Folding legs for table{Folding legs for table}

In the present invention, the folding leg attached to the bottom of the table rotates a pair of support racks located on the bottom of the top plate in a single operation and expands it in a vertical direction, and, on the contrary, rotates the support rack so that it overlaps on the bottom of the base plate and folds it, thereby strengthening the folded state. It relates to a folding leg for a table that keeps the table.

In general, folding tables are widely used indoors, such as homes or offices, where space is essential, as they can be installed by spreading the folding legs when in use, and folding the folding legs when not in use. As the number of people who engage in outdoor activities such as such increases rapidly, the number of cases of being loaded on vehicles and used outdoors is increasing.

However, when the conventional folding table is unfolded for use or folded for storage, there is a hassle of removing or assembling the legs from the table plate, and there is a risk of loss because the legs must be stored separately as described above.

In addition, Korean Patent Application No. 10-2016-0011635 "Foldable leg structure for table" A pair of guide bars fixed to the bottom of the table top, a fixing frame installed at the end of the guide bar, and a hinge pivoting on the fixing frame A support leg to be installed, a connection bar that connects the support legs and has a locking protrusion formed on one side, a support link installed with one end pivoting on the inner surface of the guide bar, and connects the support links so that the locking protrusion is caught on one side It characterized in that it consists of a support panel having a locking groove to be fitted, and a connection link connecting the support leg and the support link.

However, in order to fold or unfold the table folding leg, the linked part of the support link and the connecting link is pressed by hand and folded into a V-shaped shape, and then the support leg is rotated to fold or unfold. Safety accidents often occur in which one part is stiff and gets caught in the process of pressing or pulling strongly with the hand.

Therefore, when folding the table folding leg, there are many cases of folding or unfolding by pressing the connecting portion of the support link and the connecting link using feet instead of hands.
