Description

Safety device of folding table

Technical Field

The utility model relates to a safety device of a folding table.

Background

The table legs of the common dining table and the table for placing articles are roughly divided into a fixed type and a foldable (folding) type, and the fixed type table legs cannot be folded to occupy space and are limited by environmental space, so that most of people take the folding table; however, since the foldable table has no special mechanism to ensure that the table can be safely fixed and bear weight when the table is in an open use state, users often encounter unexpected situations, such as automatic folding due to external force collision or the like, or careless pressing and applying force on one end of the foldable table, which results in the unfortunate overturning of the foldable table.

In view of the above-mentioned disadvantages, a number of improved techniques for folding tables have been developed, as follows:

1. taiwan patent publication No. TWM430897U describes a safety buckle device for a folding table, comprising: a sleeve joint part sleeved on the support rod of the folding table and a clamping hook extending upwards from the sleeve joint part and capable of being hooked on the movable frame of the folding table, so that the folding table is not affected by external force and can be folded.

2. Taiwan patent publication No. TWM442754U describes a folding table structure (i) comprising: the table comprises a table top and a table frame, wherein the table frame is provided with two support frames so as to be fixedly arranged on the table top, and a movable frame is arranged between the two support frames; the table frame is provided with a foot rest, the foot rest is provided with a first foot rest and a second foot rest, the first foot rest and the second foot rest are in a crossed state, the top end of the first foot rest is axially arranged with the support frame, the top end of the second foot rest is axially arranged with the movable frame, the second foot rest is further provided with a fixed frame, and the fixed frame is provided with a concave ring enclosure and is used for arranging a buckling element; a fastening element, which is provided with a first fastening part and a second fastening part and is combined with the concave ring of the fixing frame by utilizing the first fastening part; when the second buckling part is combined with the movable frame, a buckling effect is generated; when the table frame and the table top are unfolded, the foot rest can be fully fixed by buckling the buckling element on the movable frame, and the foot rest can not be folded randomly after improper operation.

3. Taiwan patent publication No. TWM483009U describes a safety securing mechanism for a folding table, comprising: a tongue slot located in the center of the fixing rod; the tongue piece is positioned at the top end of the movable rod, and the front end of the tongue piece is provided with a bolt hole which can pass through a tongue piece slot when the folding table is opened; and a fixing bolt which can be inserted into the bolt hole at the front end of the tongue piece when the folding table is opened so as to fix the folding table in an opened use state and bear the pressing force at the two ends of the table plate.

By the design, the folding table can be prevented from being affected by external force to generate folding phenomenon; however, although the folding phenomenon can be achieved without external force, the use of the folding device has the following defects: that is, the fastening element is not easy to be disassembled, and when the child grabs the edge of the desk corner, although there is no folding phenomenon, the gravity is concentrated on one side, so that the whole desktop can suppress the child to be injured.
