Description

Folding table

The invention relates to a folding table, in particular to a folding table that automatically snaps and positions with each other after being unfolded.

Press, the design of the table is convenient for storage, and it is generally designed to be foldable, that is, it is unfolded when it is in use. When not in use, it can be folded to save less space, but most of the occasions where the folding table is used It is in a normal family, therefore, children often come into contact, and folding table folding injury may occur. Therefore, some operators also have a buckle device on the folding mechanism of the folding table to prevent the situation of pinching children. For example, the Republic of China New Patent Certificate No. 375431 "Structure of Fixing Device for Folding Tables" and Certificate No. M445384 "Improvement of Fixing Device Structure for Folding Tables". Although the fixing device for folding tables mentioned above can achieve the effect of preventing folding, in use, The user needs to perform additional operations to make the folding table fixed and cannot be folded, which is not only inconvenient in operation, but when the user forgets to operate the fixing device, accidents of pinching children may still occur. Therefore, the existing folding prevention structure is still improved space.

Therefore, the purpose of the present invention is to provide a folding table that can be automatically snapped and positioned after being unfolded.

Therefore, the folding table of the present invention has a table top, a first tripod pivotally connected to the table top, a second tripod pivotally connected to the first tripod, and one pivotally connected to both the table top and the second tripod When the first tripod and the second tripod expand relative to each other, and when the first tripod and the second tripod are relatively unfolded, and the tabletop is in a horizontal state, the first The bipod and the spring clips on the detent frame are automatically engaged with each other after contact, so that the detent frame and the second tripod are relatively positioned, so that the folding table is indeed positioned in the unfolded position, and has the effect of convenient operation.

FIG. 7 is a schematic cross-sectional side view of another preferred embodiment of the present invention in which the connecting rod of the folding table and the elastic clip are engaged with each other.

Referring to FIGS. 1 to 3, a preferred embodiment of the present invention has a tabletop 1 having a tabletop 2, two fixing rods 3 fixed in parallel under the tabletop 2, and one pivotally connected to the fixing rods 3 under the tabletop 2 The first tripod 4, a second tripod 5 pivotally connected to the first tripod 4, and a trigger 6 pivotally connected to the fixing rods 3 and the second tripod 5 under the table 2 , And a spring clip 7 disposed on the detent frame 6, the second tripod 5 has a horizontal connecting rod 51, the detent frame 6 is U-shaped, and has a fixed connecting rod with the table 2 below 3 The two side bars 61 pivotally connected and a cross bar 62 connecting the two side bars 61, when the first leg 4 and the second leg 5 are relatively unfolded, the lever 6 pivots accordingly and makes the cross bar 62 parallel to the connecting rod 51 correspondingly approaching, the elastic member 7 has a fixed portion 71 fixed to the cross bar 62, a curved by the fixed portion 71 The arc catching portion 72 extending by an arc, a pressing portion 73 continued by the arc catching portion 72, and two parallel reinforcing ribs 74 extending from the pressing portion 73 to the arc catching portion 72, the arc catching portion 72 is capable of accommodating The card abutting connecting rod 51 is used to enable the latching frame 6 to be snapped and positioned relative to the second tripod 5.

When the folding table 1 is unfolded, the table top 2 is in a horizontal state. At this time, the first tripod 4 and the second tripod 5 cross and unfold, and the trigger frame 6 is connected between the desktop 2 and the second tripod 5 by the first From the position shown in the figure to the position shown in the second figure, in the process of pivoting the lever 6, the cross bar 62 will gradually approach the connecting rod 51 in parallel, and the reinforcing rib 74 on the pressing portion 73 of the elastic member 7 As shown in FIG. 3, it first contacts the connecting rod 51, the pressing portion 73 is elastically displaced by the pressing of the connecting rod 51, and then, the lever 6 continues to pivot so that the pressing portion 73 of the elastic member 7 Gradually move to the position of FIG. 4 relative to the connecting rod 51, and finally move to the arc clamping portion 72, that is, the position shown in FIG. 5 and the elastic clamping member 7 is elastically snapped and positioned. At this time, the lever 6 will Due to the locking of the elastic clamping member 7, it can no longer be pivotally displaced relative to the second tripod 5, so that the folding table 1 is indeed deployed and positioned. As for the design of the reinforcing rib 74 of the elastic clamping member 7, it can be strengthened The strength of the elastic member 7, but the protruding direction of the reinforcing rib 74 can also be reversed, which can still strengthen the strength of the elastic member 7.

More specifically, during the unfolding process of the folding table 1 of the present invention, the elastic member 7 is elastically snapped against the connecting rod 51 by the elastic member 7 on the cross bar 62, and finally the connecting rod 51 is automatically elastically snapped into the arc clamping part 72 to ensure Positioning the folding table 1 in the unfolded position has the effect of convenient operation. When the folding table 1 is to be folded, as long as the pressing portion 73 of the elastic member 7 is pulled, and the table top 2 is folded at the same time, the connecting rod 51 is separated from the With the arc card portion 72, the folding table 1 can be smoothly folded.

Please refer to FIG. 6 and FIG. 7, another preferred embodiment of the present invention is that the folding table 1 also has a table top 2, a first tripod 4, a second tripod 5, a trigger 6 and a spring clip 7 The main difference from the previous embodiment is that the folding table 1 further has four fixing seats fixed under the table 2 8. The rods 61 on both sides of the first tripod 4 and the detent frame 6 are pivotally connected to the fixing bases 8 respectively. In addition, the cross rod 62 of the detent frame 6 is formed into a flat shape. It is fixed on the cross bar 62. When the folding table 1 is unfolded, the connecting rod 51 of the second tripod 5 also automatically snaps into the arc clamping part 72 of the elastic clamping member 7, so as to position the folded table 1 in unfolding position.
