Description

Technical Field

[0001] The invention relates to the technical field of stationery and sports goods, in particular to a domino that is reset sequentially. Background Art

[0002] Dominoes are a popular game. When playing, dominoes are arranged into a specific pattern at a certain distance. When the first domino is knocked down gently, the rest of the dominoes will cause a chain reaction and fall down one by one. However, after a game of dominoes is finished, the dominoes need to be manually raised, which takes a lot of time. In addition, due to mistakes during the placement process, some dominoes may fall down, causing the entire dominoes to fall down and need to be placed again.

[0003] In order to reset the dominoes, some designs put the dominoes on a special platform and use an electric mechanism to turn the dominoes from falling to standing, while others collect the dominoes on an electric trolley and then use the trolley to rearrange the dominoes. These methods all have defects, such as the platform or electric trolley has restrictions on the placement of dominoes, requires additional electric equipment, and is more complicated to operate. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the present invention combines the features of dominoes and tumblers, and proposes a domino that is reset in sequence, including a traditional domino with a solid rectangular structure located in the front row as a control domino and a plurality of tumbler dominoes with a light top and a heavy bottom as a demonstration domino. The control dominoes can control the plurality of demonstration dominoes arranged in a pattern behind to fall down or stand up in sequence following the control dominoes. The upper part of the demonstration dominoes is a hollow structure, and the lower part is a solid structure. This tumbler structure design with a light top and a heavy bottom makes the center of gravity of the demonstration dominoes close to the bottom, and the erected state is its stable equilibrium state. When erected, the center of gravity is at the lowest distance from the horizontal plane, and the center of gravity rises when it falls down.

[0005] When the control domino changes from standing up to falling down, its center of gravity lowers, and the gravitational potential energy is converted into kinetic energy. The control domino knocks down the first demonstration domino, and then the demonstration dominoes fall down in a chain reaction. When the demonstration domino changes from standing up to falling down, its center of gravity rises, and the kinetic energy is converted into gravitational potential energy, until the kinetic energy of the domino system is exhausted, and the last demonstration domino stops falling down. In order to increase the kinetic energy of the domino system and make the entire dominoes long enough, the number of control dominoes in the front row can be increased, or the combination of control dominoes and demonstration dominoes can be arranged in a cycle.

[0006] The control domino is manually erected, while the demonstration domino is in a tilted state, with its center of gravity raised and unstable. The control domino pressing on the first demonstration domino is removed, and the demonstration domino is reset to a stable equilibrium state, i.e., an upright state, under the action of gravity torque. Then the demonstration dominoes are reset to the upright state in a chain reaction.

[0007] Therefore, you only need to manually topple or stand up the control dominoes in the front row to control the multiple demonstration dominoes behind it to topple or stand up in sequence.

[0008] The technical solution adopted by the present invention is: a domino that is reset in sequence, wherein the demonstration dominoes can fall or reset in sequence following the control dominoes, and is characterized in that it comprises a control domino (1) located in the front row and a plurality of demonstration dominoes (2) behind the control dominoes, wherein the control dominoes are solid rectangular parallelepiped structures, and the demonstration dominoes are divided into upper and lower parts, wherein the upper part is a hollow rectangular parallelepiped structure (21) and the lower part is a solid structure.

[0009] Furthermore, the control dominoes (1) are made of plastic, wood or metal.

[0010] Preferably, the upper part of the demonstration dominoes (2) is made of plastic, and the lower part is made of plastic or metal or plastic with metal (22) embedded in it.

[0011] Preferably, the upper part of the demonstration dominoes (2) is made of wood, and the lower part is made of wood or metal or wood with metal (22) embedded in it.

[0012] Furthermore, the control dominoes (1) and the demonstration dominoes (2) have the same height, and the rectangular parallelepiped structure of the control dominoes and the rectangular parallelepiped structure of the upper part of the demonstration dominoes have the same length and width.

[0013] Furthermore, the number of the control dominoes (1) is at least one, and in order to increase the kinetic energy of the domino system, the number of the front row of control dominoes can be increased.

[0014] In summary, the beneficial effects of the present invention are as follows: the entire dominoes can be controlled to be dumped or reset in sequence only by manually dumping or resetting the control dominoes, the operation is convenient, and no additional electric equipment is required; the demonstration dominoes can be reset automatically as long as they are not pressed by the dominoes in front of them, and the entire dominoes will not be destroyed due to individual dominoes being dumped due to mistakes in the placement process; the dominoes are combined with the tumbler, which has the dual fun of dominoes and the tumbler, and the sequential resetting of the dominoes, like the sequential dumping, is also a spectacular sight, which adds a new way of playing and improves the fun of playing.

[0023] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figure 1 As shown, the present invention provides a domino that is reset in sequence, comprising a control domino (1) in the front row and a plurality of demonstration dominoes (2) behind the control dominoes, which are arranged in sequence on a horizontal plane to form a desired pattern. The control dominoes and the demonstration dominoes have the same shape and size, with a length, width and height of 27 mm, 9 mm and 54 mm respectively. The control dominoes are solid plastic cuboids. When the control dominoes are manually pushed down, the demonstration dominoes behind them fall down in sequence. When the control dominoes are manually lifted up, the demonstration dominoes behind them stand up in sequence.

[0026] like Figure 2 and 3 As shown, the upper part of the demonstration dominoes is a hollow plastic cuboid (21), with a cavity of 50 mm in height in the middle, and the thickness of the thin walls around the cavity is 2 mm. The solid structure at the bottom has a total height of 12 mm, including a plastic bottom shell (23) of 4 mm in height and a cuboid metal counterweight (22) embedded in the cavity. The cuboid metal block has a length, width and height of 23 mm, 5 mm and 8 mm respectively, and covers the plastic bottom shell. This tumbler design with a light top and heavy bottom lowers the center of gravity of the demonstration dominoes, so that they are in a stable and balanced state when erected. If they are not pressed by the dominoes in front, the demonstration dominoes can reset themselves to an erected state after being tilted.

[0027] Preferably, in order to prevent dust and improve appearance and avoid exposing the cavity, a cap (not shown in the accompanying drawings) may be added to the top of the cavity of the demonstration dominoes.

[0028] Example 2

[0029] like Figure 4 As shown, the present invention provides a domino that is reset in sequence, comprising two control dominoes (1) in the front row and a plurality of demonstration dominoes (2) behind the control dominoes, which are arranged in sequence on a horizontal plane to form a desired pattern. The control dominoes and the demonstration dominoes are both 54 mm in height, and the rectangular parallelepiped structure of the control dominoes and the rectangular parallelepiped structure of the upper part of the demonstration dominoes have the same length and width, which are 27 mm and 9 mm respectively. The control dominoes are solid rectangular parallelepipeds made of wood. When the first control domino is manually pushed down, the subsequent dominoes fall down in sequence. When the second control domino is manually lifted up, the subsequent demonstration dominoes stand up in sequence.

[0030] like Figure 5 , 6 As shown in 7, the upper part of the demonstration domino is a hollow rectangular block (21) made of wood, with a cavity of 44 mm in height in the middle, and the thickness of the thin walls around the cavity is 2 mm. The bottom is a solid semi-cylinder (24) made of wood with a radius of 10 mm. This tumbler design with a light top and a heavy bottom lowers the center of gravity of the demonstration domino, so that it is in a stable and balanced state when erected. If it is not pressed by the dominoes in front, the demonstration dominoes can reset themselves to an upright state after being tilted.

[0031] Preferably, in order to prevent dust and improve appearance and avoid exposing the cavity, a cap (not shown in the accompanying drawings) may be added to the top of the cavity of the demonstration dominoes.
