Description

[Detailed description of the invention] The present invention relates to a folding table tennis table that can be folded and unfolded smoothly while preventing the net from hanging down from the opposing gap between the left table tennis table and the right table tennis table. The structure of the present invention will be described in detail below with reference to the accompanying drawings showing one embodiment.

The left table tennis table 1 and the right table tennis table 2 are connected by a folding mechanism A so that they can be folded and expanded from a horizontal unfolded state to an overlapping folded state, and net support rods 4 that support a net 3 in a tensioned manner on both sides of the center part. are arranged, and each of the net support rods 4 is attached to the left table tennis table 1 by the net storage mechanism B.
A table tennis table configured to be folded and stored from an outer upright position to an inner storage position between the left and right table tennis tables 1 and 2 in response to the folding operation of the left table tennis table 1 and the right table tennis table 2. A net sagging prevention plate 5 that closes the opposing gap between the respective top plates 1a and 1b that occurs when the right table tennis table 2 is folded and prevents the net 3 from sagging due to sagging from the opposing gap is attached to one side. This device is characterized in that it is swingably provided on the top plate 1a, and configured so that the net droop prevention plate 5 is biased against the other top plate 1b.

In the folding mechanism A of this embodiment, left and right mounting racks 1b and 2b are fixed to both sides of the bottom surfaces of the left and right top plates 1a and 2a of the left and right table tennis tables 1 and 2, respectively. In the front part, there are front legs 6a having an L-shape on the side.
The upper ends of 6b are pivotally connected by front connecting pins 7a and 7b, and the upper ends of rear legs 8a and 8b are pivotally connected to the rear by rear connecting pins 9a and 9b.
Connect the left and right levers 10a, 10b between the upper parts of the front legs 6b, 8b, and the front legs connecting pins 11a, 11b.
and a left connecting plate 14a which is pivotally connected by rear leg connecting pins 12a and 12b and is pivotally connected to the abutting side ends of the left and right mounting legs 1b and 2b by a fulcrum pin 13 in an overlapping state in an X-shape. The upper ends of the right connecting plate 14b are pivotally connected by upper pivot pins 15a and 15b, and the lower end of the left connecting plate 14a is pivotally connected to the front end of the right lever 10b by a right pivot pin 16b. , the lower end of the right connecting plate 14b is pivotally connected to the front end of the left lever 10a by a left pivot pin 16a, and the upper end of the left link rod 17a is pivotally connected to the left mounting rod 1b by a left link pin 18a, and the right The upper end of the link rod 17b is pivotally connected to the right mounting rod 2b by a right link pin 18b, the lower end of the left link rod 17a is pivotally connected to the left pivot pin 16a, and the right link rod 1
The lower end of 7b is pivotally connected to the right pivot pin 16b, and stopper pieces 19a, 19 are folded on the lower sides of each of the left connecting plate 14a and the right connecting plate 14b.
b.

Further, in the net storage mechanism B of this embodiment, the lower end of a support rod 20 is pivotally connected to the fulcrum pin 13, and a vertical slide frame 21 is vertically slidably inserted through the support rod 20. A connecting piece 22 is fixed to the left and right side of the connecting piece 22, and left and right operating links 24a,
The upper end of 24b is pivotally connected, and this left operating link 2
The lower end of the right operating link 24a is pivotally connected to the left pivot pin 16a, the lower end of the right operating link 24b is pivotally connected to the right pivot pin 16b, and the upper end of the support rod 20 is pivoted by a center pin 25. The rod 26 is pivotally connected to be able to swing 90 degrees from the horizontal position to the upper end extension position of the support rod 20, and the upper end of the push/pull link 27 is connected to the base of the swing rod 26 by an upper connecting pin 28a. At the same time, the lower end is connected to the vertical slide frame 21.
is pivotally connected to the lower connecting pin 28b, and the swinging rod 2
The L-shaped net support rod 4 is fixed to the front end of the net support rod 6.

Reference numeral 29 is a rubber wheel.

Further, in the net droop prevention plate 5 of this embodiment, a mounting plate 30 is fixed to the back surface of the top plate 2a with screws 31 as shown in FIG. The net sag prevention plate 5 is pivotally mounted so as to be swingable, and a helical spring 33 is wound around the hinge pin 32, so that the helical spring 33 brings the net sag prevention plate 5 into elastic contact with the back surface of the top plate 1a. I have to.

Reference numeral 34 is a reinforcing rod.

That is, when the top plates 1a and 2a are folded from the horizontal unfolded state shown in FIG. 2 to the overlapping state shown in FIG. Since the net 3 is to be stored lying down, the net 3 sag, and due to this sagging, the net 3 hangs down from the opposing gap R that inevitably occurs, and tries to protrude outward, but the net sagging prevention plate 5 Supports the net 3 and prevents it from jumping out.

In addition, the net droop prevention plate 5 is the top plate 1a, 2
During the unfolding/folding operation of a, it swings around the hinge pin 32.

The present invention closes the opposing gap between the respective top plates 1a and 1b that occurs when the left table tennis table 1 and the right table tennis table 2 are folded to prevent the net 3 from hanging down due to sagging from the opposing gap. The net sag prevention plate 5 is swingably provided on one top plate 1a, and the net sag prevention plate 5 is configured to be biased against the other top plate 1b, so that the sagging net 3 is prevented from moving outward. As a result, when the left table tennis table 1 and the right table tennis table 2 are folded, the net 3 that protrudes from the opposing gap R will not be caught in the table. The folding behavior of the table tennis table 1 and the right table tennis table 2 is performed smoothly and satisfactorily.

Further, by arranging several net droop prevention plates 5, this droop can be further prevented.

Further, since the net droop prevention plate 5 is swingable, there is no problem in the folding and unfolding operations of the left table tennis table 1 and the right table tennis table 2.

Moreover, since it has a simple configuration, it is suitable for mass production and can be manufactured at low cost.

As described above, the present invention has excellent practical effects such as preventing the net from hanging down from the opposing gap between the left table tennis table and the right table tennis table and allowing smooth folding and unfolding. We will provide a folding table tennis table that can be used as a table tennis table.
