Description

Technical Field

[0001] This invention belongs to the field of mahjong machines, and particularly relates to a portable mahjong table. Background Technology

[0002] With the rise of lifestyles such as camping and outdoor socializing, traditional fixed mahjong tables, due to their large size, heavy weight, and inconvenience in moving, can no longer meet the mahjong entertainment needs in outdoor and small space scenarios. Although existing portable mahjong tables have made breakthroughs in terms of lightweighting and foldability, they still suffer from limited functionality and insufficient user experience. Traditional mahjong tables mostly adopt a fixed table leg design, resulting in a large overall size and heavy weight, making storage and transportation extremely inconvenient and unsuitable for small apartments, temporary gatherings, and other scenarios with limited space. While existing folding mahjong tables have solved the space problem to some extent, they still have many shortcomings: some products only fold the tabletop while the legs remain fixed, resulting in a large overall thickness and space-consuming structure when folded; some mahjong tables with foldable legs have complex folding structures and poor locking stability, causing the legs to wobble during use and affecting the gaming experience; and some products do not take into account the convenience of storage and use, with cumbersome folding and unfolding operations that do not allow for quick switching between states. Most portable mahjong tables only meet basic card-playing needs and lack supporting functions such as automatic dice rotation and card storage. When used outdoors, they require additional accessories and are cumbersome to operate.

[0003] For example, a Chinese patent discloses a folding table leg frame for a mahjong table [application number: CN200920307206.3]. Each table leg is fitted with two connecting pieces, an upper one and a lower one. The upper connecting piece is fixed to the top of the table leg and is a fixed connecting piece, while the lower connecting piece can move up and down along the body of the table leg and is a movable connecting piece. For each pair of adjacent table legs, a cross support frame with a common central pivot is installed between the top fixed connecting piece of one leg and the lower movable connecting piece of the other leg. The four table legs are connected as one unit by these four cross support frames. Summary of the Invention

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] This invention provides a portable mahjong table, combined with Figure 1-12 The table includes a tabletop 10 and a table leg assembly. The table leg assembly is rotatably connected to the bottom of the tabletop 10, allowing it to be folded for storage or supported and unfolded. The tabletop 10 is equipped with a dice turntable assembly 26, which contains dice. The rotation of the dice turntable assembly 26 can cause the internal dice to roll randomly.

[0018] The table leg assembly includes four table leg bodies 11 located at the four corners of the tabletop 10. The table leg bodies 11 are rotatably connected to the tabletop 10 via a rotating structure. In the supported and unfolded state, the table leg assembly is supported on the bottom of the tabletop 10 via a supporting structure.

[0019] In this invention, during use, the table base body 11 is rotated out of the tabletop 10 via a rotating structure, so that the tabletop 10 and the table base body 11 are placed perpendicularly, or the table base body 11 extends outward to support the tabletop 10, and the table base body 11 is fixed in place by the supporting structure. The dice turntable assembly 26 is rotatably installed inside the tabletop 10, requiring no additional accessories; rotating the dice turntable assembly 26 makes the dice roll.

[0020] Preferably, the rotating structure includes two rotating shafts 12 that are rotatably connected to the bottom of the tabletop 10, and the two ends of the rotating shafts 12 are connected to the tabletop body 11.

[0021] Preferably, a support brace 13 is connected between the tabletop body 11 and the pivot 12 to which it is connected.

[0022] In this invention, the supporting diagonal bar 13 can strengthen the support and make the mahjong table more stable.

[0023] The support structure includes a support rod 14, the two ends of which are rotatably connected to the bottom of the table base 11 and the table board 10, respectively. When the table base 11 is unfolded for support, the support rod 14 also swings and unfolds to support between the table base 11 and the table board 10. The main support rod 14 includes two branch support rods 15, which are rotatably connected to the bottom of the table base 11 and the tabletop 10, respectively. The end of one branch support rod 15 is rotatably mounted on the other branch support rod 15, and a snap-fit ​​structure is provided between the two branch support rods 15. When the main support rod 14 swings and unfolds to support the table base 11 and the tabletop 10, the two branch support rods 15 unfold and are snapped together by the snap-fit ​​structure to form a fixed state, thereby providing support.

[0024] The snap-fit ​​structure includes two snap-fit ​​grooves 16 respectively provided on the two support rods 15. One support rod 15 has a snap-fit ​​flat piece 17 on the side of the snap-fit ​​groove 16, and the other support rod 15 has a snap-fit ​​inclined piece 18 on the side of the snap-fit ​​groove 16. The end of the snap-fit ​​inclined piece 18 is provided with a buckle plate 19. In the supported unfolded state, the snap-fit ​​inclined piece 18 and the snap-fit ​​flat piece 17 abut against the side wall of the snap-fit ​​groove 16 on the other support rod 15, and the buckle plate 19 abuts against the side of the other support rod 15.

[0025] The table base body 11 is composed of at least two separable or foldable table legs 20. The table base body 11 can be disassembled to further increase portability. The lower end of the table leg 20, which is rotatably connected to the tabletop 10, is provided with an insertion groove 21, and the end of the other table leg 20 is provided with an insertion rod 22. The lower end of the insertion rod 22 is provided with a stop surface 23. When the two table legs 20 are inserted into each other, the bottom end of the insertion groove 21 rests against the stop surface 23.

[0026] Preferably, the lower end of the tabletop 10 is provided with a table leg placement area 24, and the table legs 20 are placed in the table leg placement area 24 by a snap-fit ​​structure. The snap-fit ​​structure can be a hollow placement ring into which the table legs 20 are inserted, or it can be a placement slot into which the table legs 20 are embedded.

[0027] Preferably, the lower end of the tabletop 10 is provided with a hidden storage cavity 25. In the folded storage state, the table leg assembly, rotating structure, and supporting structure are all placed inside the hidden storage cavity 25. With the table leg assembly, rotating structure, and supporting structure all housed inside the hidden storage cavity 25, from the outside, only a single tabletop 10 is visible, facilitating carrying and transportation. The dice turntable assembly 26 includes a turntable 27 rotatably connected to the tabletop 10. The turntable 27 has a dice placement cavity for placing dice. The upper opening of the dice placement cavity is sealed by a transparent sheet 28, which confines the dice inside the dice placement cavity and prevents them from escaping. The number of dice can be observed directly through the transparent sheet 28. A hand-operated ring 29 is provided around the transparent sheet 28, and the hand-operated ring 29 is disposed on the turntable 27; The outer surface of the hand-operated ring 29 is provided with grooves or protrusions. The turntable 27 is rotated by manually turning the hand-operated ring 29. The grooves or protrusions on the outer surface of the hand-operated ring 29 increase the friction between the finger and the hand-operated ring 29, so that the dice can roll fully during the finger-operated process.

[0028] The tabletop 10 also has a recessed slot 30 for placing mahjong tiles. The slot 30 is located at the edge of the tabletop 10 and has an inclined structure for placing mahjong tiles. By placing the mahjong tiles at an incline in the slot 30, the mahjong tiles are given support rather than standing upright on the table, further increasing the stability of the placement.

[0029] The inner wall of the tile placement slot 30 includes a first inclined surface 31 and a second inclined surface 32. The bottom edges of the first inclined surface 31 and the second inclined surface 32 are connected. The first inclined surface 31 is used to support the mahjong tiles when they are upright, and the second inclined surface 32 is used to support the mahjong tiles when they are covered. During outdoor use, the user may leave the area and cover the tiles with the tiles. In addition, if the mahjong tiles are accidentally tilted, they will fall onto the second inclined surface 32 and cover the tiles, preventing them from falling to the ground or facing upwards. The length of the second inclined surface 32 is greater than the length of the mahjong tile, so that the mahjong tile will not extend beyond the second inclined surface 32 when it is covered, further preventing the mahjong tile from falling off; The inner wall of the card placement slot 30 is provided with an anti-slip pad, which increases the friction between the card and the mahjong tile to prevent the tile from falling or moving due to vibration. In addition, it also reduces the noise generated by the contact between the mahjong tile and the card placement slot 30.

[0030] The tabletop 10 is also provided with a sliding drawer 33 on its lower side. The sliding drawer 33 has a support plate 34 on each side, which is located below the tabletop 10. The two support plates 34 form a drawer placement cavity and are slidably connected to the sliding drawer 33. The lower end of the support plate 34 is provided with a support surface 35, and the inner end of the support surface 35 is provided with a stop surface 36.

[0031] The sliding drawer 133 can hold chips without having to put them in a pocket or other place.

[0032] The tabletop 10 is provided with cup placement slots 37 at each of its four ends. The cup placement slots 37 are used to place cups to prevent them from tipping over due to shaking, and also to prevent the cups from being placed elsewhere and causing a cluttered scene.
