ROTATION CENTER MECHANISM OF SHIELD OPENING/CLOSING IN FAN-SHAPE
To provide a rotation center mechanism that is compact even though a shield has a structure opening/closing in a fan-shape in which one rotation shaft is used for connection.SOLUTION: A rotation center mechanism to be a rotation center in opening/closing a sunshade 28 in a fan-shape, the sunshade being a shield constituted by sunshade frames 5, 6, 7, 8, 9 that are a plurality of skeleton frames and a sunshade sheet 21 that is a shield screen supported by the sunshade frames 5, 6, 7, 8, 9 has a common rotation center shaft 11 and connection plates 31, 32, 33, 34 having different bending angles for the respective sunshade frames 5, 6, 7, 8. The respective sunshade frames 5, 6, 7, 8 are individually connected to the common rotation center shaft 11 via the connection plates 31, 32, 33, 34 and are disposed radially on the same plane so as to open/close in a fan-shape. The sunshade frames 5, 6, 7, 8, 9 are disposed so as to be in parallel with one another when the sunshade 28 is closed and are made to be spread radially when being extended.SELECTED DRAWING: Figure 1
【課題】１本の回転軸で連結して扇状に開閉する構造の遮蔽物でありながらコンパクトな回転中心機構を提供する。【解決手段】複数の骨格フレームたる日除けフレーム５，６，７，８，９と該日除けフレーム５，６，７，８，９で支持される遮蔽幕たる日除けシート２１とで構成される遮蔽物たる日除け２８を扇状に開閉させる際の回転中心となる回転中心機構において、共通の回転中心軸１１と各日除けフレーム５，６，７，８毎に異なる折れ角度の連結プレート３１，３２，３３，３４とを設け、各日除けフレーム５，６，７，８が連結プレート３１，３２，３３，３４を介して共通の回転中心軸１１と各々連結され、同一平面上に放射状に配置されて扇状に開閉するように備えられ、日除け２８を閉じた時に日除けフレーム５，６，７，８，９が互いに並行に配置されると共に拡げられた時に放射状に広げられるようにしている。【選択図】図１
