Description

[Detailed description of the invention] The invention of this application relates to the improvement of a table tennis table that can be assembled and folded freely.It has a simple structure with a small number of parts, which reduces the weight, minimizes the strength required for assembly and folding, and reduces the failure rate. The purpose is to provide an inexpensive table tennis table.

Conventionally known folding table tennis tables have been provided with relatively simple leg configurations, but they are prone to breakdowns due to the weak supporting force of the top plate, and the central joint may droop downward during use. There were drawbacks such as the fact that it interfered with play.

This invention improves on such drawbacks, and an embodiment thereof will be described with reference to the drawings.

Frame beams 2, 2' are fixed to the back surfaces of two top plates 1, 1'.

The legs 4, 4' equipped with shaft wheels 3, 3' are pivoted to the required parts 5, 5' to the frame frame, and the upper ends of the horizontal bars 6, 6' are bent A, A' to form the ceiling. The plates 1, 1' are cross-mounted 7 at the lower part of the center where they meet, the upper ends of the horizontal rods are mounted 8, 8' at the required parts of the frame crosspieces 2, 2', and the other ends of the horizontal rods are connected to the legs 4. , 4' are attached to pivots 9, 9' at the required parts to provide a folding table tennis table.

The shaft-mounted part is rotatable, and the wheels are provided with stoppers.

Since this device is constructed as described above, when folding from the assembled state shown in FIG. The central joints of the plates 1 and 1' are separated and displaced upward, and the legs 4 and 4' are drawn toward the center, changing the top plate 1 from the state shown in FIG. 2 to the state shown in FIG. , 1' are vertically arranged side by side, and the legs 4, 4' and the horizontal rods 6, 6' are also arranged side by side to complete folding, and can be moved and stored using wheels 3, 3'.

Next, when assembling from the folded state shown in Figure 3,
By expanding the outer ends of the top plates 1, 1' outward, the top plates 1, 1' become horizontal while opening in the opposite direction to when folded, so that the center matching parts meet, and the legs Legs 4 and 4' are opened outward to complete the assembly as shown in FIG.

As described above, the present invention has a configuration in which the number of parts required for the leg mechanism including the legs 4, 4' and the transverse rods 6, 6' is extremely small, so that the weight of the legs themselves can be reduced.

In addition, if the legs 4, 4 are pivoted to a required part of the frame crosspiece 2°2, for example, approximately at the center in the length direction, the top plates 1, 1 will be supported near the center of gravity, and the top plate The stability of the shaft attachments 5, 5', and 7. is improved, and only a small amount of force is required for assembly and folding.
Since no excessive force is applied to the 8, 8', 9, and 9' portions, the failure rate is significantly reduced.

In particular, as shown in FIGS. 1 and 4, the bending angles of the bends A and A' of the horizontal bars 6 and 6' should be configured so that they come into close contact with the back surfaces of the top plates 1 and 1' in the assembled state. Therefore, the central alignment of the top plates 1 and 1' is supported using the cross shaft joint 7 as a fulcrum, so the top plate 1
, 1' can be prevented from drooping in the center alignment portion, and a preferable state of use can be maintained.

Thus, the leg mechanism of this invention has a small number of members and has a simple structure, which makes it inexpensive, and also provides a folding table tennis table with stable support for the top plate, which is useful in practice.
