To prevent the user from feeling monotonous and easy to get tired. In addition, as shown in Figures 3 to 5, the cantilever arms 36, 37, 52, and 54 are designed with a narrow upper and lower spacing, so that the first cradle 30 and the second cradle 30 The moderate tilt angle of the second cradle 50 when it swings, it will not be too tilted to make people feel unstable, and it will not be too gentle to make people feel mechanically monotonous, which is ergonomic, and makes users feel stable and comfortable.

以下詳細說明本發明的動作特點，由於本發明前述實施例中，第一、二搖架30, 50的結構相似，動作亦雷同，故以第二搖架的動作為例來說明，如第4、5圖所示，由於該二左懸臂52的間距上窄下寬，且該二右懸臂54的間距上窄下寬，使得該第二搖架50前後搖擺時，本身會稍微傾斜或變化角度，能讓人感覺舒適放鬆，相較於單一吊掛點的鞦韆，其搖擺時本身的角度變化就大得多，讓人覺得刺激好玩。The following describes the action characteristics of the present invention in detail. Since the first and second cradles 30 and 50 have similar structures and the same actions in the foregoing embodiments of the present invention, the action of the second cradle is taken as an example to illustrate, as in the fourth embodiment. 5. As shown in Figure 5, since the distance between the two left cantilever arms 52 is narrow and wide at the bottom, and the distance between the two right cantilevers 54 is narrow and wide at the bottom, the second cradle 50 tilts or changes its angle slightly when it swings back and forth. , It can make people feel comfortable and relaxed. Compared with a swing with a single hanging point, the angle of its swing changes much more, which makes people feel exciting and fun.

本發明的底座之動作特點可再舉二比較例來比對說明，第一比較例如第6圖所示，若將二左懸臂52a改成間距上寬下窄的結構，其動作會完全不同，如第7圖所示，當第二搖架50a向前擺動時本身向前傾斜，而如第8圖所示，當第二搖架50a向後擺動時本身向後傾斜，讓使用者有被盪出去的感覺，較不安穩。反觀本發明的底座10，如第4圖所示，當第二搖架50向前擺動時本身向後傾斜，而如第5圖所示，當第二搖架50向後擺動時本身向前傾斜，讓使用者有被包覆住的感覺，使用時較為安穩。第二比較例則如第9圖所示，若將二左懸臂52b改成互相平行的結構，其動作也會不同，如第10圖所示，當第二搖架50b向前擺動時本身角度不變(即不會傾斜)，如第11圖所示，當第二搖架50b向後擺動時本身角度也不變(即不會傾斜)，給使用者的感覺比較機械單調，較易疲乏或無聊。The action characteristics of the base of the present invention can be compared and illustrated by two more comparative examples. The first comparison is shown in Fig. 6. If the two left cantilevers 52a are changed to a structure with a wide upper and a narrower spacing, the action will be completely different. As shown in Figure 7, when the second cradle 50a swings forward, it tilts forward, and as shown in Figure 8, when the second cradle 50a swings backward, it tilts backward, allowing the user to be swung out. The feeling is less stable. In contrast, the base 10 of the present invention, as shown in Figure 4, when the second cradle 50 swings forward, it tilts backward, and as shown in Figure 5, when the second cradle 50 swings backward, it tilts forward. It gives the user a feeling of being covered and is more stable when used. The second comparative example is as shown in Figure 9. If the two left cantilevers 52b are changed to a parallel structure, the action will be different. As shown in Figure 10, when the second cradle 50b swings forward, its angle No change (that is, it will not tilt). As shown in Figure 11, when the second cradle 50b swings backwards, its angle will not change (that is, it will not tilt). bored.

換言之，本發明的設計是經過許多實驗測試後所得出的最佳態樣，能讓使用者充分放鬆，甚至能解決部分失眠的問題，經過實際測試，當該第一搖架30與該第二搖架50位於擺動行程的中心點時，各懸臂36, 37, 52, 54與鉛垂線的夾角以4-12∘較佳，次佳為5-10∘，最佳則為6-8∘，前述實施例中該夾角約為7∘。基於本發明之設計精神，該底座之結構10可有其他變化設計，如該第一、二驅動裝置可採用其他具有往復驅動功能的機構，舉凡此等易於思及的變化，均應為本發明申請專利範圍所涵蓋。In other words, the design of the present invention is the best state obtained after many experimental tests, allowing users to fully relax, and even solve part of the problem of insomnia. After actual testing, when the first cradle 30 and the second cradle 30 When the cradle 50 is at the center point of the swing stroke, the angle between each cantilever 36, 37, 52, 54 and the plumb line is preferably 4-12∘, the second best is 5-10∘, and the best is 6-8∘. In the foregoing embodiment, the included angle is about 7∘. Based on the design spirit of the present invention, the structure 10 of the base can be designed with other changes. For example, the first and second drive devices can adopt other mechanisms with reciprocating drive function. All such changes that are easy to think of should be the present invention. Covered by the scope of the patent application.
