本実施形態における特徴は、羽根部９の支持部８への取付け構造にある。 A feature of the present embodiment resides in the mounting structure of the blade portion 9 to the support portion 8 .

羽根部９は、支持部８に固定される根元部１０と、回転することにより空気を送風する翼部１１で構成されている。支持部８の上面には、支持側連結部１３と、ネジ１７が締結されるネジ穴部１５と、を有している。羽根部９の根元部１０には、ネジ１７の一部が貫通する孔部１４と、羽根部９の根元部１０の下面には、羽根側連結部１２と、を有している。支持部８の支持側連結部１３と、羽根部９の羽根側連結部１２とが、篏合し、ネジ１７が、羽根部９の孔部１４を介して、支持部８のネジ穴部１５に締結されると、羽根部９は支持部８に固定される。 The blade portion 9 is composed of a root portion 10 fixed to the support portion 8 and a blade portion 11 that blows air by rotating. The upper surface of the support portion 8 has a support-side connecting portion 13 and a screw hole portion 15 into which a screw 17 is fastened. The root portion 10 of the blade portion 9 has a hole portion 14 through which a part of the screw 17 penetrates, and the blade side connecting portion 12 is provided on the lower surface of the root portion 10 of the blade portion 9 . The support side connection portion 13 of the support portion 8 and the blade side connection portion 12 of the blade portion 9 are fitted together, and the screw 17 is inserted into the screw hole portion 15 of the support portion 8 through the hole portion 14 of the blade portion 9. , the blade portion 9 is fixed to the support portion 8 .

具体的には、羽根部９の羽根側連結部１２は、第１羽根側連結部１２ａと、第２羽根側連結部１２ｂとを有している。羽根部９の根元部１０は、羽根部９の回転方向における前方側に第１羽根側連結部１２ａを、羽根部９の回転方向における後方側に第２羽根側連結部１２ｂを有している。孔部１４は、羽根部９の第１羽根側連結部１２ａと第２羽根側連結部１２ｂとの間に配置されている。 Specifically, the blade-side connecting portion 12 of the blade portion 9 has a first blade-side connecting portion 12a and a second blade-side connecting portion 12b. The root portion 10 of the blade portion 9 has a first blade-side connecting portion 12a on the front side in the rotational direction of the blade portion 9 and a second blade-side connecting portion 12b on the rear side in the rotational direction of the blade portion 9. . The hole portion 14 is arranged between the first blade-side connecting portion 12 a and the second blade-side connecting portion 12 b of the blade portion 9 .

また、支持部８の支持側連結部１３は、第１支持側連結部１３ａと、第２支持側連結部１３ｂとを有している。支持部８は、羽根部９の第１羽根側連結部１２ａに相対する位置には第１支持側連結部１３ａを備え、羽根部９の第２羽根側連結部１２ｂに相対する位置には第２支持側連結部１３ｂを備えている。支持部８は、羽根部９の孔部１４に相対する位置には、ネジ穴部１５を備えている。第１羽根側連結部１２ａと第１支持側連結部１３ａとが嵌合し、第２羽根側連結部１２ｂと第２支持側連結部１３ｂとが嵌合し、ネジ１７が、羽根部９の孔部１４を介して、支持部８のネジ穴部１５に締結されると、羽根部９は支持部８に固定される。 Further, the support-side connecting portion 13 of the support portion 8 has a first support-side connecting portion 13a and a second support-side connecting portion 13b. The support portion 8 includes a first support-side connection portion 13a at a position facing the first blade-side connection portion 12a of the blade portion 9, and a second support-side connection portion 13a at a position facing the second blade-side connection portion 12b of the blade portion 9. 2 support side connection part 13b is provided. The support portion 8 has a screw hole portion 15 at a position facing the hole portion 14 of the blade portion 9 . The first blade-side connection portion 12a and the first support-side connection portion 13a are fitted, the second blade-side connection portion 12b and the second support-side connection portion 13b are fitted, and the screw 17 is attached to the blade portion 9. The blade 9 is fixed to the support 8 when it is fastened to the screw hole 15 of the support 8 via the hole 14 .

一例として、第１羽根側連結部１２ａと第２羽根側連結部１２ｂとは、上方に凹んだ凹形状であり、水平断面が四角形状である。また、第１支持側連結部１３ａと第２支持側連結部１３ｂとは、上方に突出した凸形状であり、水平断面が四角形状である。 As an example, the first blade-side connecting portion 12a and the second blade-side connecting portion 12b are recessed upward and have a rectangular horizontal cross section. The first support-side connection portion 13a and the second support-side connection portion 13b have a convex shape protruding upward, and have a rectangular horizontal cross section.

すなわち、羽根部９の根元部１０に設けられた上方に凹んだ凹形状である第１羽根側連結部１２ａと第２羽根側連結部１２ｂと、相対する位置に設けられた上方に突出した凸形状である第１支持側連結部１３ａと第２支持側連結部１３ｂとが嵌合することにより、羽根部９を支持部８へ取付ける位置の精度と取付け強度が向上するものとなる。なお、第１羽根側連結部１２ａと第２羽根側連結部１２ｂとは、根元部１０の下面から下方に突出した凸形状であり、第１支持側連結部１３ａと第２支持側連結部１３ｂとは、支持部８の上面が下方に凹んだ凹形状でも良い。 That is, the first blade-side connecting portion 12a and the second blade-side connecting portion 12b, which are provided in the root portion 10 of the blade portion 9 and have an upwardly recessed concave shape, and the upwardly protruding protrusion provided at a position facing each other. By fitting the first support-side connection portion 13a and the second support-side connection portion 13b, which are shaped, the accuracy of the position of attaching the blade portion 9 to the support portion 8 and the attachment strength are improved. The first blade-side connecting portion 12a and the second blade-side connecting portion 12b have a convex shape projecting downward from the lower surface of the root portion 10, and the first supporting-side connecting portion 13a and the second supporting-side connecting portion 13b , the upper surface of the support portion 8 may be recessed downward.

ここで、羽根部９と支持部８のネジ１７による固定を、羽根部９の根元部１０のこれら第１羽根側連結部１２ａと第２羽根側連結部１２ｂとの間に設けられた孔部１４と、相対する位置に設けられたネジ穴部１５とをネジ１７による締結を１箇所とすることができるので、取付け作業時間を短縮することができるものである。 Here, the fixing of the blade portion 9 and the support portion 8 by the screws 17 is carried out through the holes provided between the first blade-side connecting portion 12a and the second blade-side connecting portion 12b of the root portion 10 of the blade portion 9. 14 and the screw hole portion 15 provided at the opposite position can be fastened with the screw 17 at one place, so that the mounting work time can be shortened.

また、支持部８の支持側連結部１３と、羽根部９の羽根側連結部１２とが、篏合しないとネジ１７をネジ穴部１５に締結できない構成である。 Further, the support side connection portion 13 of the support portion 8 and the blade side connection portion 12 of the blade portion 9 are configured so that the screw 17 cannot be fastened to the screw hole portion 15 unless the support side connection portion 13 and the blade side connection portion 12 are fitted.

具体的には、ネジ１７は、円形状の頭部１７ａと、頭部１７ａから延設され、頭部１７ａの径より小さい径の円柱状に形成された軸部１７ｂと、軸部の外周に螺旋状の凹凸により形成されたネジ部１７ｃと、を備えている。軸部１７ｂの長さは、羽根部９の根元側の上下方向の寸法より大きく、羽根部９の根元側の上下方向の寸法に、支持側連結部１３、または羽根側連結部１２の上下方向の寸法を加えた寸法より小さい。 Specifically, the screw 17 includes a circular head portion 17a, a cylindrical shaft portion 17b extending from the head portion 17a and having a diameter smaller than that of the head portion 17a, and an outer circumference of the shaft portion. and a threaded portion 17c formed by spiral unevenness. The length of the shaft portion 17 b is greater than the vertical dimension of the root side of the blade portion 9 , and is equal to the vertical dimension of the root side of the blade portion 9 in the vertical direction of the support side connecting portion 13 or the blade side connecting portion 12 . less than the dimension plus the dimension of

これにより、羽根部９の上面を下面として逆に取り付けようとした場合に、第１支持側連結部１３ａと第２支持側連結部１３ｂが、第１羽根側連結部１２ａと第２羽根側連結部１２ｂと、上手く嵌合せず、また、孔部１４である凹部があることによって、ネジ穴部１５までネジ１７が届かず、支持部８と羽根部９が締結できないため、羽根部９の逆取り付けを防止することが出来る。つまり、支持部８の支持側連結部１３と、羽根部９の羽根側連結部とが、篏合しないとネジ１７をネジ穴部１５に締結できない。 As a result, when the blade portion 9 is attached with the upper surface facing the lower surface, the first support-side connecting portion 13a and the second support-side connecting portion 13b are connected to the first blade-side connecting portion 12a and the second blade-side connecting portion 12a. The screw 17 does not reach the screw hole portion 15 due to the recess that is the hole portion 14, and the support portion 8 and the blade portion 9 cannot be fastened. Installation can be prevented. In other words, the screw 17 cannot be fastened to the screw hole portion 15 unless the support-side connection portion 13 of the support portion 8 and the blade-side connection portion of the blade portion 9 are fitted.

また、支持部８における回転中心からネジ穴部１５までの寸法は、支持部８における回転中心から支持側連結部１３までの寸法より大きい。ここで、羽根部９が回転し、翼部１１によって下方向に空気を送風する場合には、翼部１１には上方への力が発生する。つまり、羽根部９には、ネジ１７によって固定される孔部１４を境にして２種類の方向の力が発生する。羽根部９におけるネジ１７によって固定される孔部１４より先端側には、上方への力が発生し、羽根部９におけるネジ１７によって固定される孔部１４より根元側には、下方への力が発生する。これにより、支持部８における回転中心からネジ穴部１５までの寸法が、支持部８における回転中心から支持側連結部１３までの寸法より大きい場合には、支持側連結部１３と羽根側連結部１２とが、篏合する方向に力が発生する。結果として、羽根部９を支持部８へ取付け強度が向上するものとなる。 Also, the dimension from the center of rotation of the support portion 8 to the screw hole portion 15 is larger than the dimension from the center of rotation of the support portion 8 to the support-side connecting portion 13 . Here, when the blade portion 9 rotates and the wing portion 11 blows air downward, an upward force is generated in the wing portion 11 . In other words, forces in two directions are generated in the blade portion 9 with the hole portion 14 fixed by the screw 17 as a boundary. An upward force is generated on the tip side of the hole portion 14 fixed by the screw 17 in the blade portion 9, and a downward force is generated on the root side of the hole portion 14 fixed by the screw 17 in the blade portion 9. occurs. As a result, when the dimension from the rotation center of the support portion 8 to the screw hole portion 15 is larger than the dimension from the rotation center of the support portion 8 to the support side connection portion 13, the support side connection portion 13 and the blade side connection portion 12 generate a force in the direction in which they fit together. As a result, the attachment strength of the blade portion 9 to the support portion 8 is improved.

家庭用や事務用などの、天井扇風機としての活用が期待されるものである。 It is expected to be used as a ceiling fan for home and office use.
