Description

Technical Field

[0001] This invention relates to a ping-pong table, and more particularly to an adjustable ping-pong table. Background Technology

[0002] Ping pong tables have evolved from bulky cement tables fixed to the ground in the early days to sports equipment that combines high performance and human-centered design. Due to the concentration of people living in concentrated areas, the same activity space may serve multiple functions, and different sports equipment needs to be used in the same space at different times. Foldable ping pong tables can be placed anywhere.

[0003] Currently, folding ping-pong tables generally use hinged legs to support the table. When needed, the legs are folded out, and when not needed, they are folded back into the bottom of the tabletop to form a fold. Although this achieves a partial folding effect, the hinged design reduces the overall stability of the table. This makes it easy for the table to tilt or the legs to deform if the user or onlookers unintentionally apply force to the table. Furthermore, existing folding ping-pong tables still have a relatively large overall table area after folding the legs, resulting in limited adjustability.

[0004] Therefore, the purpose of this invention is to provide an adjustable table tennis table that can fold the tabletop to half its unfolded state, and fold the legs into the folded tabletop. Furthermore, it can form a multi-segment stable structure after the table is unfolded, thereby ensuring the stability of the table when unfolded and reducing the space occupied by the table after folding. This makes the table more adaptable, which is the research objective of this invention. Summary of the Invention

[0005] This invention provides an adjustable ping-pong table that can effectively solve the above-mentioned problems.

[0006] This invention is implemented as follows: An adjustable ping-pong table includes: The main body of the table includes a first plate and a second plate. The first plate and the second plate are respectively provided with a first hinge plate and a second hinge plate that are hinged to each other on both sides. The first plate and the second plate can be rotated and folded along the connection point of the first hinge plate and the second hinge plate. The folding leg assembly located at the lower ends of the first plate and the second plate includes short folding parts respectively located at the lower ends of the first plate and the second plate. A supporting folding part is locked on the lower half of the short folding part. The supporting folding part consists of a hollow rotating rod and a telescopic support rod embedded in the rotating rod. The telescopic support rod extends and abuts against the bearing surface. The inner expansion assembly includes an inner mounting base disposed within the telescopic support rod. An expansion member for closing the long rib grooves is locked onto the inner mounting base. When the telescopic support rod slides out from the rotating rod, the expansion member is removed from the long rib groove and locked onto the inner mounting base in an X-shape with the telescopic support rod.

[0007] As a further improvement, the inner mounting seat is located at the bottom of the long rib groove.

[0008] As a further improvement, the inner mounting base is provided with a partition plate that divides the inner mounting base into two symmetrical mounting chambers. Each mounting chamber includes an outer chamber fixed in a long rib groove. An inner chamber is provided inside the outer chamber. A fixing member is provided in the inner chamber, and the extension member is locked to the fixing member.

[0009] As a further improvement, the fastener includes a connecting cylinder disposed in the middle of the inner cavity, and a compression spring is sleeved on the outer side of the connecting cylinder.

[0010] As a further improvement, the extension includes a rod with the same width as the long rib groove, and a mating button seat is provided on the side of the rod near the long rib groove. The mating button seat is connected to the inner mounting base by a locking pin.

[0011] As a further improvement, the rod body is divided into a short rod section and a long rod section by the mating button seat. A folding plate is provided on the inner side of the long rod section, and the two long rod sections that are in contact with the bearing surface are connected by the folding plate.

[0012] As a further improvement, the upper end of the inner mounting base is connected to a support plate along a direction parallel to the long rib groove, and the support plate is in contact with the extension member located in the long rib groove.

[0013] As a further improvement, the first hinge plate includes a first mounting piece locked onto the first plate body, the first mounting piece having an integrally formed hinge inner tongue, the second hinge plate having a thickness greater than the first hinge plate, the second hinge plate including a second mounting piece locked onto the side of the second plate body and offset from the first mounting piece, the second mounting piece having an integrally formed hinge outer tongue embedded in the hinge inner tongue.

[0014] As a further improvement, the short folding section includes a clamping clip disposed at the lower ends of the first plate and the second plate, and a U-shaped frame is rotatably mounted inside the clamping clip. One side of the U-shaped frame is open and a buffer film is installed on the other side.

[0015] As a further improvement, the rotating rod is provided with several mounting holes, and an elastic V-plate is provided on the inner side of the upper half of the telescopic support rod. The elastic V-plate passes through the telescopic support rod through a locking pin and cooperates with one of the mounting holes.

[0016] The beneficial effects of this invention are: This invention divides the entire tabletop into two sections: a first tabletop and a second tabletop. A first hinge plate and a second hinge plate are installed between the two sections. When the tabletops are in a horizontal position, they are connected by the first and second hinge plates. When folding is needed, the tabletops can be rotated and folded along the connection point between the first and second hinge plates. This allows the tabletops to be reduced to half their original size, making it easier to adjust the space they occupy.

[0017] After the main body of the table can be folded, the traditional folding structure of the rods is obviously not suitable for this invention. This would cause the folded rods to protrude beyond half of the table body, i.e., beyond the first and second plates, occupying extra space. Therefore, this invention, through the folding leg assembly, allows the connection between the short folding part and the supporting folding part to be removed. Since the short folding part is relatively short, it can be directly folded into the lower end of the first and second plates. Then, the telescopic support rod is pressed into the inside of the rotating rod, causing the entire supporting folding part to shrink to the same length as the short folding part. The supporting folding part is then folded into the lower end of the first and second plates in the same way. This allows the folding leg assembly to be folded into the already folded table body in two stages, thereby improving the practicality of this invention.

[0018] The design of the tabletop and folding leg assembly allows both the table body and supporting rods to be folded. However, only the telescopic support rod is in contact with the load-bearing surface. Therefore, this invention addresses this issue by incorporating an internal extension component. A long rib groove is formed in the lower half of the telescopic support rod, and an internal mounting seat is installed within this groove. The extension component can be embedded within the mounting seat or locked in an X-shape. This allows the extension component to be flush with the outer circumference of the telescopic support rod when it retracts into the rotating rod. Furthermore, the extension component assists in supporting the table when the telescopic support rod supports the entire table, improving its support effect and thus enhancing the overall stability of the table, making it less prone to tilting or deformation during use.

Detailed Implementation

[0029] All embodiments of the present invention are intended to fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating that the purpose, technical solution, and advantages of the method are clearer. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Reference Figures 1 to 8 As shown, an adjustable ping-pong table includes: a table body 1, comprising a first plate 11 and a second plate 12, wherein a first hinge plate 13 and a second hinge plate 14 are respectively provided on both sides of the first plate 11 and the second plate 12, which are hinged to each other; the first plate 11 and the second plate 12 are folded and rotated along the connecting hinge point of the first hinge plate 13 and the second hinge plate 14; and a folding leg assembly 2 disposed at the lower end of the first plate 11 and the second plate 12, comprising a short folding part 21 disposed at the lower end of the first plate 11 and the second plate 12, wherein a supporting folding part 22 is locked onto the lower half of the short folding part 21, and the supporting folding part 22 is a hollow rotating rod. The system comprises a telescopic support rod 222 embedded in the rotating rod 221, wherein the telescopic support rod 222 extends and abuts against the bearing surface; and an inner extension assembly 3, wherein the telescopic support rod 222 has long rib grooves 2221 on both sides of its outer peripheral surface and the two long rib grooves 2221 are connected. The inner extension assembly 3 includes an inner mounting seat 31 disposed in the telescopic support rod 222, and an extension member 32 for closing the long rib grooves 2221 is locked on the inner mounting seat 31. When the telescopic support rod 222 slides out from the rotating rod 221, the extension member 32 is removed from the long rib grooves 2221 and locked on the inner mounting seat 31 in an X-shape with the telescopic support rod 222.

[0032] In this embodiment, both sides of the first plate 11 or the second plate 12 are provided with inner metal cylinders, and J-shaped rods are movably installed on the inner metal cylinders. The net is fixed by the two J-shaped rods, so that the net can also be movably disassembled.

[0033] The first plate 11 and the second plate 12 are respectively provided with a latch and a locking tongue, so that the latch and locking tongue can be locked and fixed after the first plate 11 and the second plate 12 are folded, preventing the first plate 11 and the second plate 12 from falling apart.

[0034] Few existing foldable pool tables exist. Therefore, in this embodiment, the main body 1 of the pool table is divided into two sections: a first plate 11 and a second plate 12. A first hinge plate 13 and a second hinge plate 14 are provided between the two plates. When the plates are in a horizontal state, they are connected by the first hinge plate 13 and the second hinge plate 14. When folding is required, the plates can be rotated and folded along the connection point between the first hinge plate 13 and the second hinge plate 14. This allows the original space occupied by the pool table plates to be reduced to half of their original size, making it easier to adjust the space they occupy.

[0035] In this embodiment, the first hinge plate 13 includes a first mounting piece 131 locked onto the first plate 11. The first mounting piece 131 has an integrally formed hinge inner tongue 132. The second hinge plate 14 has a thickness greater than the first hinge plate 13. The second hinge plate 14 includes a second mounting piece 141 locked onto the side of the second plate 12 and offset from the first mounting piece 131. The second mounting piece 141 has an integrally formed hinge outer tongue 142 embedded in the hinge inner tongue 132. Since the second hinge plate 14 has a thickness greater than the first hinge plate 13, and the second hinge plate 14 has an arc-shaped limiting piece thickened on it, the first plate 11 and the second plate 12 can only be folded inward and cannot be bent upward, thereby avoiding the phenomenon of inward concavity during use.

[0036] After the main body 1 of the table can be folded, the traditional folding structure of the rods is obviously not suitable for this invention. This would cause the folded rods to protrude beyond half of the board, that is, beyond the first board 11 and the second board 12, occupying extra space. Therefore, in this embodiment, the folding leg assembly 2, after the connection between the short folding part 21 and the supporting folding part 22 is removed, can be directly folded into the lower end of the first board 11 and the second board 12 because the short folding part 21 is relatively short. Then, the telescopic support rod 222 is pressed into the inside of the rotating rod 221, so that the entire supporting folding part 22 is folded to the same length as the short folding part 21. Then, the supporting folding part 22 is also folded into the lower end of the first board 11 and the second board 12. This allows the folding leg assembly 2 to be folded into the already folded table body 1 in a two-stage storage manner, thereby improving the practicality of this invention.

[0037] If the short folding parts 21 are scattered, the support effect of the already short folding rod will be worse. Therefore, the short folding parts 21 in this embodiment include clamping clips 211 disposed at the lower ends of the first plate 11 and the second plate 12. A U-shaped frame 212 is rotatably installed inside the clamping clips 211. One side of the U-shaped frame 212 is open and the other side is equipped with a buffer film 213. The short support rod is integrated into a U-shaped frame 212, and the support connection is achieved through the U-shaped frame 212, resulting in higher overall strength.

[0038] To enable the movable arrangement of the rotating rod 221 and the telescopic support rod 222, the rotating rod 221 in this embodiment is provided with a plurality of mounting holes 2211. An elastic V-plate 2222 is provided on the inner side of the upper half of the telescopic support rod 222. The elastic V-plate 2222 passes through the telescopic support rod 222 through a locking pin 2223 and engages with one of the mounting holes 2211. The elastic V-plate 2222 can be deformed by pressing the locking pin 2223, thereby realizing the positional change of the telescopic support rod 222 and the rotating rod 221.

[0039] The arrangement of the table body 1 and the folding leg assembly 2 allows both the table and the supporting rods to be folded. However, only the telescopic support rod 222 is in contact with the bearing surface. Therefore, this embodiment uses an internal extension assembly 3 to create a long rib groove 2221 in the lower half of the telescopic support rod 222. An internal mounting seat 31 is provided in the long rib groove 2221, and the extension member 32 can be embedded in or locked in an X-shape on the internal mounting seat 31. When the telescopic support rod 222 is retracted into the rotating rod 221, the extension member 32 can be flush with the outer circumference of the telescopic support rod 222. When the telescopic support rod 222 supports the entire table, the extension member 32 can assist in supporting the table, improving the support effect of the telescopic support rod 222, thereby improving the stability of the entire table and making it less prone to tilting and deformation during use.

[0040] The extension member 32 needs to be removed after the telescopic support rod 222 contacts the bearing surface. Therefore, the inner mounting base 31 in this embodiment is located at the bottom of the long rib groove 2221, so that after the extension member 32 is removed, it can be inverted and installed on the inner mounting base 31. The extension member 32 just contacts the bearing surface, so that the extension member 32 and the telescopic support rod 222 form an X-shaped structure and simultaneously contact the bearing surface.

[0041] Since the long rib groove 2221 is a through groove, extension members 32 need to be provided at both ends of the long rib groove 2221. Therefore, in this embodiment, the inner mounting base 31 is provided with a partition plate 33 to divide the inner mounting base 31 into two symmetrical mounting chambers. The mounting chamber includes an outer chamber 311 fixed in the long rib groove 2221. An inner chamber 312 is provided on the inner side of the outer chamber 311. A fixing member 313 is provided in the inner chamber 312. The extension member 32 is locked on the fixing member 313. The extension member 32 can be installed in both mounting chambers, and the chamber formed by the outer chamber 311 and the inner chamber 312 can be used to install the extension member 32.

[0042] When installing the expansion member 32, the outer cavity 311, and the inner cavity 312, the installation is mainly secured by the fixing member 313. Specifically, the fixing member 313 includes a connecting column 3131 located in the middle of the inner cavity 312. A compression spring 3132 is sleeved on the outer side of the connecting column 3131. The connecting column 3131 can be connected to the internally threaded connecting column 3131 by bolts, and the compression spring 3132 can effectively position the device.

[0043] When the extension member 32 is engaged with the long rib groove 2221, it can fit completely. Specifically, the extension member 32 includes a rod 321 with the same width as the long rib groove 2221. A mating button seat 322 is provided on the side of the rod 321 near the long rib groove 2221. The mating button seat 322 is connected to the inner mounting base 31 by a locking pin 323. In this embodiment, the shape of the mating button seat 322 matches the cavity formed by the outer cavity 311 and the inner cavity 312. Since the cavity formed by the outer cavity 311 and the inner cavity 312 is square, the shape of the mating button seat 322 is also square.

[0044] The rod 321 is not a single rod. Specifically, the rod 321 is divided into a short rod 3211 and a long rod 3212 by the mating knob seat 322. The inner side of the long rod 3212 is provided with a folding plate 3213. The two long rods 3212 that are in contact with the bearing surface are connected by the folding plate 3213. The folding plate 3213 can be folded out by a hinge. Adjacent folding plates 3213 form an associated structure and are connected by screws, thereby making the rod 321 more stable.

[0045] When the extension member 32 is engaged with the long rib groove 2221, since the extension member 32 is only connected to the inner mounting base 31, the upper end of the inner mounting base 31 in this embodiment is connected with a support plate 34 in a direction parallel to the long rib groove 2221. The support plate 34 fits against the extension member 32 located in the long rib groove 2221, so that the extension member 32 can have more contact surface and is more stable when embedded in the long rib groove 2221.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
