且上端側樞接於各頂板背面之左右支持腳、配設於各支持 腳與鉸鏈間之連接桿以及於左右支持腳架所架設之繫桿等 :其可變成展開位置（使用狀態），將前述連接桿之內端側樞 接於鉸鏈適當位置，同時，將前述連接桿之中間部樞接於 支持腳之中高部位，左右頂板藉此受各支持腳水平支持， 以及折疊狀態（收納狀態），左右頂板以其表面側相對之方式 立起，同時，各支持腳沿前述頂板背面立起。 此種內折型折疊式桌球台於上述展開狀態利用各支持* 腳以水平支持頂板來使用，另一方面，於收納時藉由折疊 成上述折疊狀態可縮小收納空間。 【發明內容】 (一）發明所欲解決之技術問題 根據上述習知折疊式桌球台，由於左右頂板係重物， 故折疊時，若將兩頂板之後端向上推至一定位置’鉸鏈、 支持腳、連接桿等之連接功能即起作用，使兩頂板急速地 3Γ ^00301147 大致垂直立起，又，在展開時，若將左右頂板後端向下壓 至一定位置，即同樣地，連接功能起作用，兩頂板急速展 開，雖然有可迅速展開、折疊之優點，不過，在操作時須 十分小心。 。還有，由於各頂板係重物，故在上述展開、折疊時，左 右頂板後端側各站一個作業者，各作業者將頂板向上推或 向下壓至一定位置，不但需要極大勞力，而且當有一作業 者於上推、下壓同一邊頂板時之力量較強時，頂板有可能 倒向另一作業者側，因此，不但更須慎重作業，而且有老® 人或兒童等操作困難之問題。 本發明係有鑑於此種習知情事而提出者，其目的在於 提供一種即使一個作業者亦容易進行左右頂板之展開、折 疊作業，同時，作業時之安全性亦佳，老人、兒童、殘障 者等亦可容易操作之折疊式桌球台。 (二）解決問題之技術手段 爲了達成以上目的，本申請案之第1發明爲一種折疊® 式桌球台，係具備左右頂板1、Γ、設於該兩頂板前端1 a、

invention belongs] The present invention relates to a folding pool table, particularly an inwardly folding pool table, which can be turned into a folded state in which the left and right top plates are opposed to each other on the surface side. (Storage state), and the unfolded state (used state) where the two top plates are expanded substantially horizontally. [Prior art] It has been known in the past that this type of pool table has left and right top plates, inward hinges provided under the butt edges of the two top plates as front end sides, casters # at the lower end, and the upper end sides are pivotally connected to the left and right of the top plates. Support feet, connecting rods arranged between each supporting foot and the hinge, and tie rods erected on the left and right supporting feet, etc .: It can be turned into a deployed position (use state), and the inner end of the connecting rod is pivotally connected to the hinge At the same time, at the same time, the middle part of the connecting rod is pivoted to the mid-high part of the support foot, so that the left and right top plates are horizontally supported by each support foot, and in the folded state (storage state), the left and right top plates stand in such a manner that their surface sides are opposite to each other. At the same time, each support leg stands up along the back of the top plate. This in-folding folding pool table uses the support * feet to support the top plate horizontally in the unfolded state. On the other hand, the storage space can be reduced by folding into the folded state during storage. [Summary of the invention] (1) The technical problem to be solved by the invention According to the above-mentioned conventional folding pool table, since the left and right top plates are heavy objects, when folding, if the rear ends of the two top plates are pushed up to a certain position, the hinges and support feet The connection functions of the connecting rods, etc. work, which makes the two top plates rapidly 3Γ ^ 00301147 standing upright, and when the rear ends of the left and right top plates are pressed down to a certain position during the deployment, the connection function also works. Function, the two top plates are rapidly unfolded. Although there is the advantage of being able to quickly unfold and fold, you must be very careful during operation. . In addition, since each top plate is a heavy object, during the above-mentioned unfolding and folding, there is one operator at each rear end of the left and right top plates, and each operator pushes the top plate up or down to a certain position, which not only requires great labor, but also When a worker is strong when pushing up and down on the same side of the roof, the roof may fall to the side of the other operator. Therefore, not only must the operator be more careful, but also there are difficult operations such as old people or children. problem. The present invention was developed in view of such knowledge, and its object is to provide a single operator who can easily perform unfolding and folding of the left and right top plates. At the same time, the safety during the operation is also good. The elderly, children, and the disabled Folding pool table that can be easily operated. (II) Technical means to solve the problem In order to achieve the above purpose, the first invention of the present application is a foldable® billiard table, which is provided with left and right top plates 1, Γ, provided at the front ends of the two top plates 1 a, la 'butt back Inward-folding hinges 2, 2 ', with casters 3, 3' at the lower end and pivotal connections 4, 4 'at the upper end side, left and right support feet 5, 5 on the back of each top plate, and arranged at the aforementioned hinges 2, 2' The link mechanism 6, 6 'between the support feet 5, 5'; by the aforementioned hinges 2, 2 'and the link mechanisms 6, 6', it can be turned into left and right top plates 1, 1, and the supported feet 5, 5 'are horizontal Support the unfolded state, and the left and right top plates 1, 1, turn around the aforementioned hinges 2, 2 'as the center, and stand up with the surface side facing ^ 200301147, and support feet 5, 5 and stand along the back of these top plates It is folded inwardly; it is characterized in that gas left and right top plates 1, 1, and the back side are provided with gas dampers 7, 7 'which elastically press the top plates in the direction of folding, and use these gas dampers to Assist the folding action of the aforementioned top plates 1, 1 'and perform buffering when the top plates 1, Γ are unfolded . When formed in this way, the telescopic rods of the gas damper are in a contracted state when the left and right top plates are horizontally supported by the supporting feet. If the left and right top plates are turned in the folding direction from this state, the telescopic rods of the gas damper are extended to two The top plate's turning in the folding direction exerts an elastic pressure, and the elastic pressure is used to make the ® folded state, that is, the two top plates will stand up with their surface sides facing each other 'while supporting the feet to stand up and fold along the back of the panels. Therefore, by arbitrarily adjusting the elasticity of the telescopic rod of the gas damper, the rotation speed of the left and right top plates in the folding direction can be appropriately set during the aforementioned folding action, which can greatly reduce the labor required when the two top plates are folded. In addition, if the two top plates in the folded state are rotated in the unfolding direction, the telescopic rod of the gas damper is contracted due to the weight of each top plate, and the two top plates are unfolded. At this time, even if each top plate is rapidly turned in the unfolding direction due to its own weight , The shrinkage load (elastic force) of the gas damper will also reduce the rotation speed *, which can improve the safety of the deployment operation. It goes without saying that by arbitrarily adjusting the elastic force (contracting force) of the telescopic rod of the gas damper, the rotation speed of the left and right top plates in the unfolding direction can be appropriately set during the unfolding. Therefore, the labor required for folding and unfolding the top plate can be greatly reduced, and at the same time, the safety of operation can be greatly improved.

As shown in FIG. 1, the left and right top plates 1, Γ are supported horizontally and unfolded by the supporting feet 5, 5 'during use. At this time, the casters 7, 7 'is in a contracted state, and at the same time, in each locking mechanism 50, 50', turn the knob 52 in the screwing direction, so that the sliding of the pivot shaft (the rotation of the rotation levers 10, 10 ') cannot be performed, and the gas damper is prevented 7, 7 'stretched and locked and unfolded. At this time, when the horizontality of the left and right top plates 1 and Γ varies due to the relationship with the installation ground B, the arbitrary adjustment mechanisms 60 and 60 ′ at the corners of the left and right top plates 1 and Γ face the positive or Turn the knob 62 in the opposite direction, and the screw 61 moves forward and backward to raise or lower the corners of the top plate 1 and Γ to adjust the level. In the case where the pool table A is stored, in each of the locking mechanisms 50 and 50 ', the knob 52 is turned in the direction of loosening, the pivot shaft 51 is slid (the rotation levers 10 and 10' are rotated), and the gas damper 7 , 7 'can be stretched. After releasing the lock in the unfolded state, if the left and right top plates 1, Γ are pushed up slightly in the direction of folding, the rods 18, 18' of the gas damper 7, 7 'are stretched, and the spring is used.

When the billiard table is restored from the folded state shown in FIG. 3, in each locking mechanism 50, 50 ', turn the knob 52 in the direction of unscrewing to release the lock in the folded state, and then move toward the unfolding direction. When the left and right top plates 1 and Γ are pressed down, the rods 18 and 18 'of the gas dampers 7, 7' will shrink due to the weight of each top plate 1, Γ. At the same time, the two top plates 1, Γ are restored by their weights. It is an unfolded state supported by the supporting feet 5, 5 'horizontally. At this time, by the elastic force of the gas dampers 7, 7 'to withstand the impact force of the top plate 1, 1', the rotation of the top plate * 1, Γ is slowed, and the impact when the top plate 1, Γ is unfolded is slowed to ensure the safety of the operation And reduce the sound of unfolding. Figs. 10 to 13 show a so-called general-type folding pool table A 'used for official games or those who are physically fit. This snooker table A 'adds the outer supporting feet 15, 15' to the snooker table A illustrated in Figs. 1 to 9A to 9C, and provides adjustment mechanisms 70 and 70 'instead of the aforementioned adjustment mechanisms 60 and 60'. The other constituent elements are the same as the aforementioned pool table A, so 18 ^ 200301147 in the figure is marked with the same symbol as above, and the repeated descriptions and drawings are omitted. Only the differences will be described below. That is, the billiard table A 'of this example uses the aforementioned supporting feet 5,5' as the inner sides 5,5 ', and has outer supporting feet 15,15 near the top end of the top plate 1, Γ, and the outer supporting feet 15 And 15 ', which are equipped with adjusting mechanisms 70 and 70' at the lower end, and pivotably connect the 14 and 14 'to the back of each top plate at the upper end side; the formalities are formed by these inner and outer support feet 5, 5', 15, 15 ' A so-called general-type folding pool table used for competitions or those who are physically fit. The pool table A 'does not include the above-mentioned connecting rods 8 and 8', but has a connecting rod 16, 16 'disposed between each of the hinges 2, 2' and the outer support legs 15, 15 ', and a rotating rod 10 10 'from the middle of each connecting rod 16, 16' to the rear of the back of each top plate. In addition, the front ends of the connecting rods 16, 16 'are pivotably pivoted 11, 11' to the lower portions of the hinges 2, 2 ', and the middle ends of the connecting rods are pivotably pivoted to the front ends of the 12, 12' rotational rods 10, 10 '. , And pivotally pivot the rear ends of the levers 10 and 10 'to the back of the top plate in a rotatable and sliding manner, and pivot the rear ends of the connecting levers 16 and 16' to pivot 19'19 'to the outside for free support. With feet 15, 15 ', the pool table A' can be transformed into: the left and right top plates 1, Γ supported horizontally by the inner and outer support @hold feet 5, 5 ', 15, 15' horizontally, and the left and right top plates 1, Γ with hinges 2, 2 'is a fulcrum, and the front side is facing up, and the inner and outer supporting feet 5, 5', 15, 15 'stand up along the back of the top plate and are folded inward. The adjusting mechanisms 70 and 70 'in this example are the screw shafts 71 and 71' screwed to the lower ends of the outer support legs 15, 15 ', and the adjusting legs 72 and 72 are installed at the lower ends. Forward rotation operation, the adjustment feet 72, 72 will rise 19 3Γ, 200301147, push the corners of the left and right top plates l, 1 'upward, on the other hand, by the reverse rotation operation of the adjustment feet 72, 72', The adjustment legs 72 and 72 'are lowered, and the corners of the left and right top plates 1, 1' are lowered. The above-used folding pool table A ′ is basically used in the same way as the aforementioned pool table A. When used, as shown in FIG. 10, the left and right top plates 1, Γ are at the level of the inner and outer support feet 5, 5, 15, 15 '. At this time, the gas dampers 7, 7 'are in a contracted state. At the same time, the locking mechanisms 50, 50' are used to prevent the gas dampers 7, 7 'from being stretched, and the expanded state is locked. At this time, in the case where the level of the left and right top plates 1, Γ is deviated due to the relationship with the placement ground B, in any of the corner adjustment mechanisms 70, 70 'of the left and right top plates 1, Γ, Turn the adjusting feet 72, 72 'in the forward or reverse direction to raise or lower the corners of the top plate 1 and Γ to adjust the level. In the case of the pool table A5, in each locking mechanism 50, 50', Turn the knob 52 in the loosening direction, so that the gas dampers 7, 7 'can be extended to release the locking of the unfolded state. After that, push the left and right top plates 1, Γ slightly upward in the folding direction, and the gas dampers 7, 7' The rods 18, 18 'are stretched, and by this spring pressure, the two top plates 1, 1' are turned in the folding direction. The two top plates 1, 1 'stand up with their surface sides facing each other, and support the feet 5, 5' inside and outside. , 15, 15 'Fold along the back of this top plate 1, Γ (refer to Figure 11 to Figure 12). This folding operation can also be performed by one operator standing on the sides of the butt edges of the left and right top plates 1, Γ, and rotating the two top plates 1, Γ in the folding direction. At this time, the impact absorbing materials 80 and 80 'prevent the surface sides of the two top plates 1 and 1' from coming into close contact during the folding, and the aforementioned operator can perform the folding operation without worrying that his fingers are caught between the two top plates. After the folding is completed, in each of the locking mechanisms 50, 50 ', the knob 52 is turned in the tightening direction to prevent the contraction action of the gas dampers 7, 7' to lock the folded state. In the case where the folded state is restored from the folded state shown in FIG. 12, each of the locking mechanisms 50 and 50 ′ is operated to release the locking of the aforementioned folded state. After that, if the left and right top plates 1 and Γ are pressed down in the direction of deployment, both the fixed amount and The gas dampers 7, 7 'shrink due to the weight of the top plates 1, Γ. At the same time, the two top plates 1, 1' rotate due to their own weight, and the snooker table is restored to receive the inner and outer support feet 5, 5 ', 15®, 15 'horizontal support for the expanded state. At this time, by the elastic force of the gas dampers 7, 7 'to withstand the impact force of the top plate 1, Γ, the rotation of the top plate 1, 1' is slowed down, and the impact when the top plate 1, Γ is unfolded is slowed to ensure the safety of the operation and Reduce the sound of unfolding. Although the embodiments of the folding pool table of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated examples, and it goes without saying that various changes can be made within the scope of the technical ideas described in the scope of each patent application.

The impact sound makes it easy, quick and quiet to store and set up the billiard table, especially considering the operation of children, the elderly, the disabled, etc. By using the gas damper, one operator can stand on the left and right ^ 200301147 roof On the side near the butt edge, look around and carry out the folding and unfolding of the left and right top plates, and only after confirming that there are no obstacles or people around the pool table. Therefore, it is possible to provide a novel folding pool table with excellent operability and high safety during storage and use. According to the second invention, in addition to the effects of the first invention, there is provided, for example, a so-called barrier-free pool table which can also be used by disabled persons, elderly people, patients, etc. who need a wheelchair. According to the third invention, in addition to the effects of the first invention, it is possible to provide a so-called general pool table which can also be used for, for example, formal matches. ® According to the fourth invention, in addition to the effects of the first to third inventions, it can reduce the number of parts and the number of parts because it can use the least air damper, can also assist the folding action of the left and right top plates, and cushion the two top plates when unfolding. Or assembly related labor, cost, etc. According to the fifth invention, in addition to the effects of the first to fourth inventions, the left and right top plates can not be folded or unfolded by mistake while the gas damper is actuated during the use or storage of the snooker table, or in the folded state, which can further improve the operation. _ safety. According to the sixth invention, in addition to the effects of the first to fifth inventions, even if the level of the left and right top plates deviates due to the relationship with the ground on which the billiard table is placed, etc., the level can be corrected by the operation of the adjustment mechanism. degree. According to the seventh invention, in addition to the effects of the first to sixth inventions, it is possible to prevent the close contact between the top surface surfaces of the left and right top plates when the left and right top plates are folded by impact absorption, to further improve the safety of the folding operation. According to the eighth invention, it is possible to provide a hinge that connects the left and right top plates in an inward-folding and freely rotating manner by using a reinforcing 22 ^ 200301147 member provided on the back of the top plate. Compared with the conventional hinge, it can provide a reduced number of parts, and Simplifies the installation of the top plate, and is suitable for the hinge of the inside folding folding pool table.
