BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a folding integrated ping foot table, and more particularly, to a folding integrated ping pong table which is easy to store.

A ping pong table is a device that is installed outdoors or indoors to enjoy table tennis.

However, the conventional ping-pong table is made up of two separate tables and has to be assembled separately every time it is folded and folded, which is inconvenient. In addition, there was a problem that it was difficult to raise and lower a heavy table when folded and folded.

Thus, a folding table tennis table as shown in Fig. 1 emerged.

However, when the folding table tennis table of FIG. 1 is folded, both the table tennis tables are not closely contacted and a slight gap L is generated. The legs (in particular, the vertical legs) f1, f2, f3, and f4 of the bottom portions of both the ping-pong tables are not brought into close contact with the bottom surface of the ping-pong table but kept open to the outside at a predetermined angle. In order to store the folding table as shown in FIG. 1, the folding table is usually kept in a folded state. Especially, when a plurality of folding table tennis tables are stored, the table tennis tables can not be kept in close contact with each other.

FIG. 2 is a view showing a configuration of a folding type integrated table-tennis table according to an embodiment of the present invention, FIG. 3 is an enlarged view of part A of FIG. 2, FIG. 5 is a state view when the folding type integrated ping pong table according to the embodiment of the present invention is completely folded, FIG. 6 is a state view showing folding integrated ping pong table according to the embodiment of the present invention, 6 is a state diagram showing a coupling state between the hinge and the link in FIG.

The folding type integrated ping-pong table according to the embodiment of the present invention includes a hinge portion provided on the horizontal legs 14 and 15 at the bottom of both the ping pong tables 1 and 2 and a hinge portion provided between the hinge portion and the bottom surfaces of the ping pong tables 1 and 2 And a link portion which is installed so as to fold or unfold both the table tennis tables 1 and 2.

The hinge portion is provided at the center of the horizontal legs (14) and (15). Here, the horizontal legs 14 and 15 are spaced apart from each other in the longitudinal direction of the ping-pong table when the ping-pong tables 1 and 2 are spread out to form a single ping-pong table. That is, the horizontal leg 14 is located at the center between the vertical leg 10 and the vertical leg 11, and the horizontal leg 15 is located at the center between the vertical leg 12 and the vertical leg 13. The vertical legs 10, 11, 12 and 13 and the horizontal legs 14 and 15 support both the table tennis tables 1 and 2 at their respective positions.

Each of the hinge portions includes brackets 16, 17 provided so as to face each other and spaced apart from each other. The bracket 16 is fixed to one side of the upper surface of the horizontal leg 14 and the bracket 17 is fixed to the other side of the upper surface of the horizontal leg 14. The bracket 16 and the bracket 17 may be integrally formed in a shape of a trapezoid.

2 to 4, reference numerals are given only to the brackets 16 and 17 of the hinge portion provided on the horizontal leg 14. Since the horizontal leg 15 is also provided with a hinge portion having the same structure, We think that bracket can be easily understood even if it does not have a separate reference code. In FIG. 4, the coupling state between the hinge portion and the link is expressed to be easy to understand, and a more specific coupling state can be understood more precisely through FIG. 11 which will be described later.

The link portion may be composed of six links 18, 19, 20, 21, 30, 31. The six links 18, 19, 20, 21, 30, 31 are in the form of a date.

One end of the first link 18 is rotatably installed on a vertical leg 10 rotatably provided on the bottom surface of one of the ping-pong tables (for example, the left ping-pong table) 1, And is installed on the upper portion of the bracket 17 via the connecting link 30. [ Here, the structure in which one end of the first link 18 is rotatably installed can be easily understood by anyone skilled in the art.

The other end of the first link 18 is rotatably connected to one end of the first connecting link 30 via a pin 47. [ The other end of the first connection link 30 is rotatably connected to the upper portion of the bracket 17 via a pin 46.

One end of the second link (19) is rotatably installed on the bottom surface of one of the table tennis rails (1). The structure in which one end of the second link 19 can be rotatably installed can be easily understood by anyone skilled in the art. The other end of the second link 19 is rotatably installed at the bottom of the bracket 16 via a pin 42. [ The first link 18 and the second link 19 are interconnected via a pin 41. Since the pin 41 interconnects the first link 18 and the second link 19, it can be referred to as a connection pin. That is, the pin 41 is installed at a position that is a predetermined distance from the other end of the first link 18 and a predetermined distance from the other end of the second link 19 to one end. The mounting positions of the pins 41, 42, 46 and 47 may be pivot points at which the first link 18, the second link 19, and the first connecting link 30 can rotate.

On the other hand, one end of the third link 20 is rotatably installed on a vertical leg 11 rotatably provided on a bottom surface of the other table tennis table (for example, the right table tennis table) 2. The other end of the third link 20 is installed on the upper portion of the bracket 17 via the second connection link 31. Here, the structure in which one end of the third link 20 can be rotatably installed can be easily understood by anyone skilled in the art. The other end of the third link 20 is rotatably connected to one end of the second connection link 31 via a pin 45. [ The other end of the second connection link 31 is rotatably connected to the upper portion of the bracket 17 via a pin 46. [ One end of the fourth link (21) is rotatably installed on the bottom surface of the other table tennis base (2). The structure in which one end of the fourth link 21 can be rotatably installed can be easily understood by anyone skilled in the art. The other end of the fourth link 21 is rotatably installed on the bottom of the bracket 16 via a pin 43. [ The third link 20 and the fourth link 21 are interconnected via a pin 44. The pin 44 connects the third link 20 and the fourth link 21 to each other and can be referred to as a connection pin. A pin 44 is installed at a position which is a predetermined distance from the other end of the third link 20 and a predetermined distance from the other end of the fourth link 21 to one end. Here, the mounting positions of the pins 43, 44, 45, and 46 may be the pivot point at which the third link 20, the fourth link 21, and the second connecting link 31 can rotate.

In Fig. 3, reference numerals 14a, 14b, 15a and 15b denote rollers. 4 shows the bracket 16 removed to show the connection relationship of the link portion.

When the folding type integrated ping pong table of the present invention having the above-described structure is completely folded, the state shown in Fig. 5 is obtained. That is, in comparison with the related art, the conventional folding table tennis table (see FIG. 1) does not have the two table tennis tables close to each other, but the folding table tennis table according to the embodiment of the present invention is brought into close contact with both table tennis tables. In addition, although the conventional folding type ping-pong table is not completely brought into close contact with the bottom surface of the ping-pong table when folded, the folding ping-pong table according to the embodiment of the present invention closely contacts the bottom surface of the ping pong table. Thus, the folding table rack according to the embodiment of the present invention occupies less storage space than the conventional folding table rack, and is easier to store and can prevent safety accidents because the vertical legs do not protrude.

Meanwhile, only one of the table tennis tables can be folded as shown in FIG. 6, if necessary, in the folding type integrated table tennis table according to the embodiment of the present invention. In Fig. 6, the ping-pong table 1 is in the unfolded state and only the ping-pong table 2 is folded. As shown in FIG. 6, when only one of the ping-pong tables (i.e., the right ping-pong table 2) is folded, the links 18, 19, 20 and 21 of the link portion will have the same shape as shown in FIG.

FIG. 8 is a view showing a link state when the folding type integrated ping pong table according to the embodiment of the present invention is completely folded. 8 shows links 18, 19 and 30 connected to the left ping-pong table 1 among the ping-pong tables 1 and 2 on both sides. The links to the right ping-pong table 2 will also be located as shown in Fig.

The first link 18 and the second link 19 will be positioned perpendicular to the horizontal leg 14 and the first link 18 and the second link 19 will be located at the other end of the first link 18 when the folding type integrated ping- One end of the connected first connection link 30 is directed downward.

9 is a view showing a link state when the folding type integrated ping pong table according to the embodiment of the present invention is extended to some extent. 9 shows links 18, 19 and 30 connected to the left ping-pong table 1 among the ping-pong tables 1 and 2 on both sides. The links to the right ping-pong table 2 will also be located as shown in FIG.

When the folding type integrated ping-pong table according to the embodiment of the present invention is folded or unfolded to about 30 to 40 degrees, the first link 18 and the second link 19 are separated from each other by a predetermined angle, The first connecting link 30 connected to the other end of the first leg 18 will be positioned substantially parallel to the horizontal leg 14.

FIG. 10 is a view showing a link state when the folding type integrated ping pong table according to the embodiment of the present invention is fully opened. In Fig. 10, links 18, 19 and 30 connected to the left ping-pong table 1 among the two ping-pong tables 1 and 2 are shown. The links to the right ping-pong table 2 will also be positioned as shown in Fig.

The first link 18 and the second link 19 are rotated more freely than the first and second links 18 and 19, The first connection link 30 connected to the first link 18 is aligned with the first link 18.

FIG. 11 is a plan view showing more specifically the coupling state between the hinge and the link in FIG. 2. FIG.

In Fig. 11, it can be seen that the first link 18 and the second link 19 are rotatably coupled to each other with the pin 41 as a turning point. It can be seen that the second link 19 is rotatably coupled to the brackets 16 and 17 with the pin 42 as a turning point.

It can also be seen that the first link 18 and the first connecting link 30 are rotatably coupled to each other with the pin 47 as a turning point. More specifically, the other end of the first link 18 (that is, the portion to be engaged with the first connection link 30) is formed in a shape of a trapezoid. One end of the first connecting link 30 (i.e., the portion to be engaged with the first link 18) is fitted in the shape of the diagonal of the first link 18. At this time, the pin 47 is inserted so as to penetrate the coupling portion between the first link 18 and the first connection link 30. [

It can be seen that the first connection link 30 is rotatably coupled to the brackets 16 and 17 with the pin 46 as a pivot point.

It can be seen that the third link 20 and the fourth link 21 are rotatably coupled to each other with the pin 44 as a turning point. It can be seen that the fourth link 21 is rotatably coupled to the brackets 16 and 17 with the pin 43 as a turning point.

It can also be seen that the third link 20 and the second connecting link 31 are rotatably coupled to each other with the pin 45 as a turning point. More specifically, the other end of the third link 20 (that is, a portion coupled with the second connection link 31) is formed in a trapezoidal shape. One end of the second connecting link 31 (that is, a portion to be engaged with the third link 20) is fitted in the shape of the diagonal of the third link 20. At this time, the pin 45 is fitted so as to penetrate the joint portion between the third link 20 and the second connection link 31.

On the other hand, it can be seen that the second connection link 31 is rotatably coupled to the brackets 16, 17 with the pin 46 as a pivot point.

12 is a graph showing an angle difference between the first link and the second link shown in FIG.

For example, when both the ping-pong tables are completely folded, the first link 18 and the second link 19 will be at right angles to the horizontal leg 14, so that they will maintain the state shown in Fig. 8, There is no difference.

On the other hand, when both the ping-pong tables are folded or unfolded to some extent, the first link 18 and the second link 19 are rotated with the pins 41, 42, 46, 47 as turning points. At this time, the pivot angles of the first link 18 and the second link 19 are different from each other in accordance with the rotation of the pivot table at a predetermined position where the both ping pong tables are folded. That is, as shown in FIG. 11, the pivot angles of the first link 18 and the second link 19 differ from each other at certain positions while both the ping-pong tables are being folded or unfolded.

And, when both the ping-pong tables are fully opened, the angular difference between the first link 18 and the second link 19 will be the greatest.

Although only the angle difference between the first link 18 and the second link 19 is described in the above-described FIG. 12, the angular difference between the third link 20 and the fourth link 21, It will be understood that the angular difference between the first link 18 and the second link 19 will be generated.

FIG. 13 is a view illustrating a structure in which a damper is added to a folding type integrated ping pong table according to an embodiment of the present invention.

13 differs from the folding type integrated ping-pong table according to the embodiment of the present invention in that the dampers 50 and 51 are added.

13, a damper 50 is additionally provided between the first link 18 and the horizontal leg 14 and a damper 51 is provided between the third link 20 and the horizontal leg 14 There is a difference in being installed. 13, a damper 50 is provided between the link corresponding to the first link 18 and the horizontal leg 14 among the links on the opposite side not shown by the links 18, 19, 20, A damper 51 will be installed between the link corresponding to the 3 link 20 and the horizontal leg 14.

Here, the dampers 50 and 51 may be constituted by, for example, a hydraulic damper.

According to the configuration of FIG. 13 described above, when the user grasps the end of the folded integral type ping-pong table and pivots slightly, the extended dampers 50 and 51 start to contract. As the dampers 50, 51 are contracted, the folded table-base is gradually unfolded. When the dampers 50, 51 are completely unfolded, the further dampers 50, 51 do not contract.

Then, when the user slightly lifts the end of the spreading table, expansion (expansion) of the shrunk dampers 50, 51 starts. As the dampers 50 and 51 are stretched, the spreading table is slowly folded. When the dampers 50 and 51 are completely folded, there is no further extension action of the dampers 50 and 51.

As described above, when the dampers 50 and 51 are further used, the force of the user is reduced when the ping-pong table is folded or unfolded. In particular, when folding the table tennis table on both sides, there is no fear of fingers getting caught between the table tennis tables on both sides.

As described above, an optimal embodiment has been disclosed in the drawings and specification. While specific terms have been employed herein, they are used for the purpose of describing the invention only and are not used to limit the scope of the invention as defined in the claims or the claims.
