Description

[Detailed Description of the Invention] The present invention relates to a connection structure for supporting legs in a folding table.

That is, in a folding table configured by pivoting the upper part of each support leg below the end side of the deck,
When folding the supporting legs, even if you hold the deck with your fingers on the underside of the deck above the supporting legs, you can fold it safely without pinching your fingers, and the supporting legs can be easily assembled. To provide a safe and simple structure in which a stopper part that may pinch fingers is not exposed to the outside, and to be easy to manufacture and suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a partially cutaway side view of the entire table. At the bottom of both sides of the long rectangular deck A, there are support pipes 1 made of square pipes with their ends extending to the end of the deck A. At the same time, each support leg B made of a square pipe is attached to the lower part of the four corners, and a bending rod 8 that becomes a stay is attached to the part of the support pipe 1 near each support leg B. Both ends are pivotally connected via connecting pins 9 and 10, respectively,
Both ends of the connecting rod 11 are fixed to the inner surfaces of both supporting legs B, B which are adjacent to each other on both ends of the deck A, and both ends of the connecting rod 12 are similarly fixed to the inner surface of one end side of the adjacent bending rods 8, 8. Configure. a hole 13 that can fit into each end of the support pipe 1 and through which the screw 7 is inserted;
The entire supporting piece 2 is made of a resin material so as to extend from the square body 2c with Support piece 2
A concave surface 2b is formed on the side surface of the lower half so that the thickness is about half the width of the upper part, and the concave surface 2b has a circular lower surface with a lateral direction through which a rivet-shaped support shaft 4 can be inserted. A shaft hole 14 is bored in the concave surface 2b.
The shaft hole 14 is constructed by forming arcuate long grooves 5, 5 symmetrically around the shaft hole 14.

In addition, the entire connecting piece 3 is made of a resin material so that it extends from the square body 3a that can be fitted to the upper end of each support leg B and fixed by inserting a screw 15. The width of the body 3a is about half the width of the support piece 2, and the upper part of the connecting piece 3 is formed so as to be in contact with the concave surface 2b of the support piece 2 so as to be in a fitted state. The connecting piece 3 is formed into a circular shape, and a shaft hole 16 is bored in the center of the connecting piece 3 into which the support shaft 4 can be inserted. Protrusions 6, 6
A protective piece 3b is formed on the back side of the square body 3a.
are integrally formed and configured.

Therefore, when assembling, each square body 2c is fitted into the support pipe 1 and screws 7 are inserted to secure it to the deck A, and each square body 3a is attached to the top of the support leg B. Fit and fix with screws 15,
The protrusions 6, 6 are respectively fitted into the long grooves 5, 5 so that the side surfaces of the connecting piece 3 are aligned with the concave surface 2b of the support piece 2, and the support shaft 4 is inserted into the shaft holes 16, 14 from one side to form a riveted structure. When tightened, each support leg B
This means that the upper part can be pivoted and assembled.

Then, by rotating the support leg B around the support shaft 4, the protrusions 6, 6 are aligned with the long grooves 5,
5, each support leg B can be vertically installed and deployed in a state where the bending rod 8 is extended and abuts against one end side of the support pipe 1. As shown in FIG. 12, the protrusions 6, 6 abut against the other ends of the long grooves 5, 5, and the bending rod 8 bends.
It can be folded as shown in the figure, but as shown in Figure 3, in order to hold the deck A, even if you put your fingers on the underside of the deck A, which is the upper side of the support leg B, you will not be able to get your fingers between them. This means that it can be folded without any problems.

As described above, the present invention is a folding table configured by pivoting the upper part of each support leg B to the lower end side of the deck A, and the top surface 2a is connected to the end of the support pipe 1 fixed to the lower surface of the deck A. A concave surface 2b is formed on the lower side surface of the support piece 2 which is to be joined to the lower surface of the deck A, and the supporting leg B is in contact with the concave surface 2b.
The upper connecting piece 3 is pivotally attached to the supporting piece 2 via a support shaft 4, and the facing concave surface 2b and the side surface of the connecting piece 3 have an arcuate long groove 5 on one side and a long groove 5 on the other side. Since the protrusions 6 are respectively formed to allow the support leg B to be folded, even if you insert your fingers into the lower surface of the deck A above the support leg B to grasp the deck A, you can safely grasp and fold the support leg B without being pinched. is possible,
In addition, by fitting the protrusion 6 into the long groove 5 and inserting the support shaft 4, the support leg B can be easily assembled, and the stopper part that may pinch fingers is exposed to the outside. It can be made into a safe and simple structure without any friction, and the rotation of the supporting leg B can be restricted by the engagement of the long groove 5 and the protrusion 6, so that it can be unfolded and folded safely without putting stress on each part. It has the feature that it can be carried out suitably.
