DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the accompanying drawings, embodiments of the present invention will be described in detail. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Fig. 1, a ping-pong table 1 according to an embodiment of the present invention is a detachable ping-pong table composed of a pair of structures having the same structure. More specifically, it is a removable folding table tennis table which can be laid down in a substantially horizontal state or erected in a substantially vertical state according to the needs of the user.

The above-described table tennis base 1 includes an upper plate 100, a leg member 200 rotatably provided on the upper plate 100, and a supporting member 300 supporting the leg member 200.

The upper plate 100 is a plate having a predetermined thickness provided on the upper surface of the playing surface. A movable member 220 to be described later and angles 110 to 130 for mounting the holding member 210 and the receiving member 300 are provided on the lower surface of the upper plate 100.

The leg member 200 includes a fixing member 210 for mounting the ping-pong table 1, a movable member 220 for moving the ping-pong table 1, a connecting member 230 for accommodating the ping pong table 1, . The upper end of the fixed member 210 is hinged to the first angle 110 and the upper end of the movable member 220 is hinged to the second angle 120. Both ends of the connecting member 230 are hinged to the stopping portions of the fixing member 210 and the movable member 220, respectively. At this time, adjusting means 240 for aligning the upper plate 100 is installed at the lower end of the fixing member 210, and a caster 250 for moving is provided at the lower end of the movable member 220.

According to the structure of the upper plate 100 and the leg member 200 described above, when the upper plate 100 is laid down to mount the ping-pong table 1, the connecting member 230 pushes the fixing member 210, So that the fixing member 210 is substantially at right angles (see Fig. 1). On the other hand, when the upper plate 100 is set up to accommodate the ping pong table 1, the connecting member 230 pulls the fixing member 210 so as to be substantially parallel to the upper plate 100 (see FIG. 5).

The support member 300 is a means for preventing an external force from being applied to the leg member 200 to prevent the top plate 100 from being conducted while the ping-pong table 1 is installed. The supporting member 300 is installed between the upper plate 100 and the fixing member 210 and extends in the oblique direction when the upper plate 100 and the fixing member 210 are at right angles to support the fixing member 210 . That is, the upper plate 100 can be held in a horizontal state when the ping-pong table 1 is installed.

The receiving member 300 will be described in detail with reference to FIGS. 2 to 4. FIG.

The supporting member 300 includes a first link 310 having one end hinged to the third angle 130 and a second link 320 having the other end hinged to the fixing member 210, A first hinge shaft 340 for hinging one end of the third link 330 and the other end of the first link 310 to each other; And a second hinge shaft 340 hinged to the other end of the third link 330 and one end of the second link 320.

The first link 310 and the second link 320 have a bar shape having a predetermined length. Both ends of the first link 310 and the second link 320 are formed in a semicircular shape to prevent interference with the third angle 130 and the fixing member 210 when the first link 310 and the second link 320 are rotated. Both ends of the first link 310 and the second link 320 are formed with through holes 312 and 322 for hinge connection.

The third link 330 is in the form of a channel having a C-shaped section (channel, C-shaped steel). A pair of first plates 332 that are in contact with the front and rear surfaces of the first link 310 and the second link 320 respectively and a pair of first plates 332 And a second plate member 334 connecting the upper ends. A first hinge hole 336 through which the first hinge shaft 340 passes is formed on one end side of the first plate member 332 and a second hinge hole 336 through which the second hinge shaft 350 passes is formed on the other end side of the first plate member 332. [ Two hinge holes 338 are formed.

Here, the second plate 334 serves as a stopper for restricting the rotation of the first link 310 and the second link 320. That is, the first and second links 310 and 320 hinged to the first and second hinge shafts 340 and 350 can rotate only until they form 180 degrees with the third link 330, 3 Links 310 to 330 can be arranged in a row when fully deployed.

The first hinge hole 336 and the second hinge hole 338 of the first hinge shaft 340 and the second hinge shaft 350 are coupled to the first hinge hole 338 and the second hinge hole 338, 336). This allows the second link 320 coupled to the second hinge shaft 350 to be deployed 180 degrees or more (see FIG. 2). In this case, the fixing member 210 is rotated by using the supporting member 330, Can be reliably supported. Particularly, as shown in FIG. 2, when the support protrusion 260 is added to the fixing member 210, the fixing member 210 can be more reliably supported.

The first hinge hole 336 formed on one end side of the first plate member 332 is circular and the second hinge hole 338 formed on the other end side of the first plate member 332 is connected to the third link 330, In the form of a slot extending in the lengthwise direction. More specifically, the second hinge hole 338 includes first and second end portions 338a and 338b formed in a semicircular shape and a curved portion 338c connecting the first and second end portions 338a and 338b . At this time, the second end portion 338b is a semicircular shape having a larger diameter than the first end portion 338a, and a locking protrusion 339 is formed between the second end portion 338b and the curved portion 338c.

The reason why the second hinge hole 338 is formed in a slot shape is to move the second hinge shaft 350 in the longitudinal direction of the third link 330. As a result, To accommodate changes in length that occur when folding or unfolding links 310-330. The latching jaw 339 prevents the second hinge shaft 350 from moving along the second hinge hole 338 when the first to third links 310 to 330 are fully extended.

Referring to Figs. 5 to 7, the installation and storage process of the ping pong table 1 according to the present embodiment will be described.

5 shows a state in which the upper plate 100 is vertically erected to accommodate the table tennis base 1. A fixing member 210 hinged to the lower surface of the upper plate 100 and a movable member 220 are disposed in close contact with the upper plate 100 so as to be parallel to each other. At this time, the first hinge point H1 and the second hinge point H2, which are fixed to both ends of the support member 300, are in a state of being close to each other, that is, between the first hinge point H1 and the second hinge point H2 Since the spacing distance is minimum, the receiving member 300 is folded into a U-shape so as to accommodate a shortened separation distance.

When the end portion of the upper plate 100 is pulled in the direction of the arrow in FIG. 6 to install the table tennis base 1, the upper plate 100 rotates about the third hinge point H3 and the connecting member 230 is fixed The member 210 is pushed and separated from the top plate 100. The supporting member 300 gradually expands as the first hinge point H1 and the second hinge point H2 are spaced apart. At this time, the second hinge shaft 350 provided at one end of the second link 320 moves along the second hinge hole 338 to accommodate a change in the separation distance.

7, when the upper plate 100 is laid horizontally, the fixing member 210 and the movable member 220 are perpendicular to the upper plate 100, and the connecting member 230 is parallel to the upper plate 100 . At this time, the first hinge point H1 and the second hinge point H2, which are fixed at both ends of the receiving member 300, are separated from each other, that is, between the first hinge point H1 and the second hinge point H2 The supporting member 300 is fully extended to accommodate the separation distance. In particular, since the second link 320 coupled to the second hinge shaft 350 is deployed more than 180 degrees to form an obtuse angle with the third link 330, the fastening member 210 can be reliably .
