Description
本發明關於一種兒童玩具，尤指一種能訓練兒童手眼協調能力的玩具。 The invention relates to a children's toy, in particular to a toy capable of training children's hand-eye coordination ability.
兒童在成長之間，身體各部位的協調能力是十分重要的，可透過一些玩具的訓練來增進，尤其是手眼協調性的訓練，有關其將來行為能力的好壞，尤應注重。 Children's ability to coordinate between different parts of the body is very important. It can be improved through the training of some toys, especially the coordination of hand-eye coordination. It is especially important to pay attention to its future behavioral ability.
在中華民國新型專利公告號481040「具動作控制與協調性玩具」前案中，揭露了一種具動作控制與協調性玩具，其係於一握持桿之中段設有複數大小不同之承接筒，各承接筒由基部呈向外逐漸擴張之開口，而握持桿端部與各承接筒銜接之部位以一繫繩銜接一拋球體，該拋球體表側設有複數組貫穿中心之貫孔，而握持桿端部銜接繫繩部位之旁側另向外延伸一尖錐部，利用揮動握持桿經由繫繩拉拋該拋球體，並以承接筒承接該拋球體，或以該尖錐部穿刺拋球體之貫孔，可達到動作控制靈敏度與身體各部協調性之訓練、增進等功效者。但此前案之玩具，無法達到手眼協調之訓練能功。 In the former case of the Republic of China New Patent Bulletin No. 481040, "Action Control and Coordination Toys", a toy with motion control and coordination is disclosed, which is provided with a plurality of sockets of different sizes in the middle of a grip bar. Each of the receiving cylinders has an opening which gradually expands outward from the base portion, and a portion of the gripping rod end that is engaged with each of the receiving cylinders is connected by a tether to a throwing ball, and the surface of the throwing ball body is provided with a plurality of through holes penetrating through the center. The tip end of the gripping rod is connected to the side of the tether portion and extends outwardly with a pointed taper portion. The throwing ball is pulled and pulled by the waving gripping rod, and the tossing body is received by the receiving cylinder, or the tapered portion is taken by the receiving cylinder. Puncture the ball through the hole, can achieve the action control sensitivity and coordination of the various parts of the body training, promotion and other effects. However, the toy of the previous case cannot achieve the training ability of hand-eye coordination.
又如，在中華民國新型專利公告號294049「中心固定旋轉式重力迷宮盤」前案中，揭露了一種中心固定旋轉式重力迷宮盤，主要為一圓形盤體，內設多組圓弧板而形成為迷宮走道，整體為利用中心軸固設在其他支撐物體上，成為可以旋轉之狀態，乃提供幼童遊樂使用，且可培養其訓練方向感之特性者。然而，此前案也無法達到有效的手眼協調之訓練能功。 In another example, in the case of the Republic of China new patent announcement No. 294049 "Center fixed rotary gravity labyrinth", a central fixed rotary gravity labyrinth disk is disclosed, which is mainly a circular disk body with multiple sets of circular arc plates. It is formed as a labyrinth aisle, and is entirely fixed on other supporting objects by the central axis, and is in a state of being rotatable, and is provided for the use of young children to play and to cultivate the characteristics of the training direction. However, the previous case also failed to achieve effective hand-eye coordination training.
