The specific embodiment

Described accompanying drawing has shown the preferred embodiment of the present invention that can be applicable to ping-pong table.

Fig. 1 has shown the plane of the ping-pong table 1 that launches in order to play ball.Clearly, the advantage that this state and the present invention can provide is irrelevant, because the standard size of this desktop has determined the space that whole ball table must occupy, and the demonstration of above-mentioned accompanying drawing is to be used for illustration purpose.

This folding table 1 comprises by two halves 2, the 2 ' desktop that constitutes, and this two

halves

2,2 ' is hinged on two hinges 18 that respectively are in these folding table 1 one sides, especially can be as seen from Figure 6.This two

halves

2,2 ' can be launched to form single plane or be placed to parallel to each other near the location being used for transportation or depositing, and under desktop, have one with described desk suitably highly to be supported on ground shelf.

In order to help to understand the fold mechanism of the following stated, be equal to the Reference numeral with symmetric element on the two halves of expression folding table 1 structure, its difference only is symbol (').For example, described figure shows that the two

halves

2,2 ' of folding table 1 has adopted identical Reference numeral (2), only exists aforesaid difference between the two.

The fold mechanism that is arranged under the desk 1 can be seen the most clearly at Fig. 3.This fold mechanism also can be used as the shelf of table support 1.It comprises two hinged quadrilateral structures substantially, and this structure is known in other industry and mechanical field.Half and

half part

2,2 ' of this desk 1 has corresponding articulated quadrilateral.For example, in half part 2, this quadrangle comprises

table leg

5 or 6, support bar 7, line segment CD (C is the pin joint of this support bar 7 about desktop half part 2 ' on opposite) and line segment AD (A is

table leg

5 or 6 pin joints about pairing desktop half part 2).Because support bar 7 can be connected in two

table legs

5,6 end of any, perhaps from hereinafter seeing, it can be connected on the reinforcement cross bar 9 that two

table legs

5,6 are combined (although preferable, inessential), and wherein a line segment has been restricted to

table leg

5 or 6; According to the required mechanical strength of material of making desk 1 in various situations, desk 1 also can have more support rods 7.From the Fig. 6 that shows desk 1 bottom, can more clearly see all these elements.

Second half part 2 ' at desk 1 has been symmetrical arranged same articulated quadrilateral structure.Tetragonal four summit A, B, C, D (herein or be A ', B ', C ', D) are the pin joints that constitutes the corresponding line segment on its each limit, thereby this structure can fold, thereby tetragonal each limit is in couples near the location.In order to make the folding best folded state that reaches the possible minimum that takes up space of desk 1, thereby make two

halves

2,2 ' substantially parallel and abut against folding mutually, must meet the following conditions: in the quadrangle, BC+CD=BA+AD, and in another quadrangle, B ' C '+C ' D=B ' A '+A ' D.This has guaranteed to satisfy summit BAD and has become 180 ° substantially with BCD, and line segment AD and BA, and BC roughly becomes two straight lines respectively with CD.By respectively A, B and C being replaced with A ', B ' and C ', can push away for second half part 2 ' also is same situation.

The

corresponding support bar

7,7 ', 8 and 8 ' hinged place on the hinge 18 of two

halves

2 and 2 ' of some C and C '.

Among Fig. 6 and Fig. 7, the axle 19 that can see hinge 18 is positioned at when desk launches under the level heights by the plane of the two halves of launching 2,2 ' formation, and is positioned on the vertical plane that adjacent edge limited by the two halves of desk 1.This means when desk 1 folds, be in the two halves 2 of desk 1 folding position, 2 ' (Fig. 4) is used for transportation near the location parallel to each other or deposits, thereby occupy less space, therefore as the European standard defined, the space enters (Fig. 4 b) less than 110mm to prevent adult and children between the desktop.This can give the credit to the motion of the axle 19 of hinge 18, and it can allow the adjacent edge of two halves leave by rotating mutually, and existing desk can't be accomplished this point.

Fig. 4 is in the side view of complete deployed condition for desk 1 as shown in Figure 3.From this figure and especially Fig. 4 b (for clearer, center table leg 12,12 ' lid save) in can see, this desk 1 takes up space and reduces as much as possible, thereby desk can be left in the house or for example in any zone of vacating of sports equipment.And the angled structure of

table leg

5,5 ', 6,6 ' base helps to provide sufficient stability to desk 1, so that transport it into desired location.As can be seen, the whole thickness of folding back desk 1 is only slightly bigger than desktop two

halves

2,2 ' sum.Fig. 5 has shown the desk 1 that launches fully, and in the figure, can be clear that more that two summits are respectively the articulated quadrilateral structure of A, B, C and D and A ', B ', C ' and D.Described two tetragonal eight summits are hinged, and satisfy above-mentioned condition BC+CD=BA+AD and B ' C '+C ' D=B ' A '+A ' D, thereby half part 2 of desktop can almost flatly parallelly be folded with second half part 2 '.

Though use light material so that the transportation of desk 1 is desirable, and the assembling economy that makes desk 1 is convenient also to be the basic demand that will reach, but for purpose of the present invention, the material of making described quadrilateral structure or described desk 1 shelf is not main points of the present invention.And the element connection or the shape that constitute the articulated quadrilateral of described shelf neither main points of the present invention.Basic sides of the present invention is to have the above geometry that constitutes and two complementary articulated quadrilateral structures allowing desk 1 be folded fully.

What the present invention will consider is to move or to transport such desk 1 as far as possible easily on the other hand.For this reason, this desk 1 has one group of

wheel

10,10 ', 11,11 ' that is positioned at

corresponding table leg

5,5 ', 6,6 ' bottom.In case this desk 1 is fully folded, it can move and occupy less space more easily.

Preferred embodiment of the present invention also comprises two center support legs 12,12 ', and this center support leg strengthens its stability when desk 1 is in expanded position.These center support legs 12,12 ' are to connect by the cross bar that constitutes 18 19 on hinge, and they can reach according to the required additional stability of desk and depend on the desired robustness of employed material in the various situations.

Center table leg 12,12 ' is supported by the bar portion hinged place of the rotating shaft 19 of hinge 18, thereby and can accept the rotation of folded desk.
