Description of the Invention: [Technical Field] The present invention relates to a fan system for mounting blade iron and blades, and more particularly to a system for automatically balancing blade iron and blades of a fan. '[Prior Art] There are many different types of fans today, such as ceiling fans, table fans, floor fans, and fans that are used in conjunction with mechanical equipment. Most of these fans include a blade ❹ and a blade mount or blade iron that couples the blade to the motor. Electric ceiling fans typically mount the motor in a fixed enclosure that is suspended from the ceiling. In operation, the motor rotates in an annular array of blade extensions or respective extensions in the form of blade iron. Each blade iron is attached to the hole of the blade and enters the piece of iron in the blade iron. Next, the blade iron is coupled to the blade to the motor by coupling the blades of the ceiling fan to the blade by passing the mounting screws through the threaded holes in the blade. Fan blade imbalance and associated ceiling fan sway may be due to a variety of imbalances associated with the ceiling fan blade to balance the deviation (4), including blade pitch angle, dihedral angle variation, and unevenness between adjacent blade pairs Circumferential spacing, blade warpage and uneven radial spacing of the blades from the vertical axis of rotation. The swaying of the ceiling fan and the associated vibrations produce undesirable noise that is often distracting and can adversely affect the life of the ceiling fan. The knives are therefore still visible as needed to quickly and easily balance the rotating blades. SUMMARY OF THE INVENTION In a preferred form of the invention, (4) (iv) an annular array of sheets of iron, the knobs of which are “toward the movement of the lamp between the motor and the blade iron; Ceiling fan blades, which are associated with each of the blade irons; and the tether system 'which interconnects the blade irons with each other, and the radial movement of the blade irons in the middle of the blade then moves all of the blade irons towards the equilibrium position. 'The movement of the blade iron (4) causes the system to move at least - the other leaves move toward the equilibrium position. ^, 〇 [Embodiment] Referring next to the drawing, a ceiling fan 1 〇 is shown, which is installed in addition to the blade iron and the blade iron. There is a conventional construction outside the system. The ceiling fan includes an electric motor 13' which is connected to a power source by an electric wire (not shown). The blade iron mounting system 14 is coupled to the bottom mounting plate 15 of the motor 13. The motor bottom mounting plate 15 has An annular array of threaded mounting bores 9. The blade iron mounting system 14 includes an annular mounting plate 24, an annular array of blade iron anti-rotation blocks 25, and an annular array of blade irons 26 having coupling To the blade 27. By mounting the mounting screw 34 through the mounting hole 35 in the mounting plate 24 and screwing it into the mounting hole 19 of the motor mounting plate 15, the mounting plate is attached to the motor mounting plate 15. Mounting plate 24 also includes an annular array of five inner pulley mounts 28 and an annular array of five outer pulley mounts 29. By screwing the screws 37 through the two oppositely disposed screw holes 38 in the mounting block 25 and being screwed Among the threaded screw holes 39 in the mounting plate 24, each anti-rotation block 25 is mounted to the mounting plate 24. The anti-rotation block 25 also includes a threaded mounting hole 40 therein. I37693.doc 200938733 Each blade iron 26 includes mounting A flange 41 and a blade mount 42 opposite the mounting flange 41. The mounting flange 41 includes a radially aligned elongated slot 44 and a mounting aperture 45. The elongated slot 44 is sized and shaped to receive an anti-set therein The block 25 is rotated and the blade iron 26 is allowed to move radially relative to the mounting plate 24, i.e., the elongated slot 44 is longer in length than the anti-rotation block so that the blade iron can move radially forward and backward. The mounting screw 47 passes through the spring washer 48 and Screwed into the anti-rotation block installation 40 maintains the vertical position of the blade iron with respect to the mounting plate 15. The blade iron five pulley fixing member 49 is coupled to the blade iron mounting hole 45. Most of the following 'a series of five cables 5〇 (the number of which is equal to the blade iron 26) The number) is interwoven between the plurality of inner pulley mounts 28, the outer pulley mounts 29 and the blade iron pulley mounts 49, as described in more detail below. The pulley mounts 28, 29 and 49 each have a center post and are mounted to Five individual pulleys for the center pillar.

如圖2中最佳展示，每一纜繩或子纜繩系統藉由其相應 滑輪固定件49耦接至所有葉片鐵。圖2所示之纜繩藉由主 葉片鐵26A之移動而被致動。纜繩50環繞葉片鐵滑輪固定 ® 件49八之外側、與位於主葉片鐵26A之任一側之葉片鐵26B 相關聯之葉片鐵滑輪固定件49B之外側以及與大體上與主 葉片鐵26A相對之葉片鐵26C相關聯之葉片鐵滑輪固定件 49C之内側。纜繩5〇亦環繞鄰近於葉片鐵26B之内部滑輪 固定件28B之内側以及環繞外部滑輪固定件29B及29(：之外 側。圖2所示之纜繩之同一組態與四個其他葉片鐵26b及 26C中之每一者相關聯。如此，每一葉片鐵藉由該一系列 五個纜繩50中之每一纜繩5〇而耦接至所有其他葉片鐵。 137693.doc 200938733 ❹ 在使用中，如圊3及4中最佳描繪，藉由給馬達通電以便 旋轉安裝板15及其相關聯之葉片鐵，較重之主葉片鐵26 a 及相關聯之葉片（描繪為主葉片鐵26A)之向外或外侧移動 致使在滑輪固定件49A處在相同之外側方向上在纜繩上施 加張力。窥繩50上之拉力導致在葉片鐵滑輪固定件49B上 產生纔繩牵拉，進而使其在内側或向内方向上移動。纜繩 50上之拉力亦導致在葉片鐵滑輪固定件49c上在外側或向 外方向上產生纜繩牽拉。如此，使緊鄰主葉片鐵26A之葉 片鐵26B向内移動，同時使大體上與主葉片鐵26A相對之 葉片鐵26C向外移動，如圖4中之箭頭所描繪。葉片鐵 26A、26B及26C以及相關聯之葉片之此等移動使得五個葉 片鐵及葉片之質量中心朝旋轉中心移動，即較重之主葉片 鐵26A及葉片藉由鄰近葉片鐵之内側移動及相對設置之葉 片鐵之外側移動而得到補償。質量中心之移動導致葉片鐵 及葉片之自動平衡’進而減少吊扇之搖晃。當然，因為每 -葉片鐵與所有五個徵繩相關聯，所以平衡位置與五個規 繩及互連之葉片鐵中之每一者之協調相關聯。 應理解’可使用_釘來固持滑輪固定件並將其用作較佳 實施例中所描繪之螺釘之替代物。 應理解，該系統將同樣適用於多個葉片鐵及葉片組合失 衡之情況，因為整個系統將移動到平衡位置。 應理解，本發明並非意欲限於吊扇且可同樣應用於所有 類型之風扇。而且，葉片數目可發生變化且不限於較 施例中所展示之五葉片系統。 貫 137693.doc 200938733 因此可見現在提供-種自身平衡之吊扇。雖然已特別參 考本發明之較佳實施例而詳細描述了本發明，但應理解， 除了明確闡述的彼等内容以外，亦可在不脫離如以下申請 專利範圍中所陳述之本發明之精神及範疇之情沉下對其作 出眾多修改、添加及刪除。 【圖式簡單說明】 圖1為呈較佳形式實施本發明之原理之吊扇之透視圖。 圖2為圖1之吊扇之一部分之仰視圖，其展示一葉片鐵之 纜繩系統。 圖3為圖1之吊扇之一部分之仰視圖，其被展示為處於中 立位置。 圖4為圖1之吊扇之一部分之仰視圖，其展示為處於補償 平衡位置。 圖5為圖1之吊扇之一部分之部分分解圖。 【主要元件符號說明】 10 吊扇 13 電動馬達 14 葉片鐵安裝系統 15 底部安裝板 19 帶螺紋安裝孔 24 環形安裝板 25 葉片鐵防旋轉塊 26 葉片鐵 26Α 主葉片鐵 137693.doc • 8 - 200938733 26Β 葉片鐵 26C 葉片鐵 27 葉片 28 内部滑輪固定件 29 外部滑輪固定件 * 29Β 外部滑輪固定件 29C 外部滑輪固定件 34 安裝螺釘 35 安裝孔 37 螺釘 38 螺釘孔 39 帶螺紋螺釘孔 40 帶螺紋安裝孔 41 安裝凸緣 42 葉片固定件 44 細長狹槽 參 45 安裝孔 47 安裝螺釘 48 彈簧墊圈 49 葉片鐵五滑輪固定件 49Α 葉片鐵滑輪固定件 49Β 葉片鐵滑輪固定件 49C 葉片鐵滑輪固定件 50 纜繩 137693.doc -9-As best shown in Figure 2, each cable or sub-cable system is coupled to all of the blade irons by its respective pulley mounts 49. The cable shown in Fig. 2 is actuated by the movement of the main blade iron 26A. The cable 50 surrounds the outer side of the blade iron pulley fixing member 49, the outer side of the blade iron pulley fixing member 49B associated with the blade iron 26B on either side of the main blade iron 26A, and is substantially opposite to the main blade iron 26A. The inner side of the blade iron pulley fixing member 49C associated with the blade iron 26C. The cable 5 turns around the inner side of the inner pulley mount 28B adjacent to the blade iron 26B and around the outer pulley mounts 29B and 29 (the outer side. The same configuration of the cable shown in Fig. 2 and the four other blade irons 26b and Each of the 26Cs is associated. Thus, each blade iron is coupled to all other blade irons by each of the series of five cables 50. 137693.doc 200938733 ❹ In use, such as Best depicted in 圊 3 and 4, by energizing the motor to rotate the mounting plate 15 and its associated blade iron, the direction of the heavier main blade iron 26 a and the associated blade (depicted as the main blade iron 26A) The outer or outer movement causes tension to be applied to the cable in the same outer side direction at the pulley mount 49A. The pulling force on the sling 50 causes the rope pull on the blade iron pulley mount 49B, thereby causing it to be inside or Moving inwardly. The pulling force on the cable 50 also causes cable pulling in the outer or outer direction on the blade iron pulley fixing member 49c. Thus, the blade iron 26B adjacent to the main blade iron 26A is moved inward while Make the general The main blade iron 26A moves outwardly relative to the blade iron 26C, as depicted by the arrows in Figure 4. These movements of the blade irons 26A, 26B and 26C and associated blades cause the center of mass of the five blade irons and blades to rotate The center movement, that is, the heavier main blade iron 26A and the blade are compensated by the movement of the inner side of the adjacent blade iron and the movement of the opposite side of the blade iron. The movement of the center of mass causes the blade iron and the blade to automatically balance 'and thereby reduce the ceiling fan Shake. Of course, because each-blade iron is associated with all five ropes, the equilibrium position is associated with the coordination of each of the five gauge ropes and the interconnected blade iron. It should be understood that 'it can be used_nail To hold the pulley mount and use it as a substitute for the screw depicted in the preferred embodiment. It should be understood that the system would be equally applicable to multiple blade iron and blade combination imbalances as the entire system will move to equilibrium It should be understood that the present invention is not intended to be limited to ceiling fans and can be equally applied to all types of fans. Moreover, the number of blades can vary and is not limited to the more embodiments. The five-blade system shown in the article. 137 693.doc 200938733 It can thus be seen that a self-balancing ceiling fan is now provided. While the invention has been described in detail with particular reference to the preferred embodiments of the invention, it should be understood In addition to the contents of the present invention, many modifications, additions and deletions may be made without departing from the spirit and scope of the invention as set forth in the following claims.
