Abstract: front page image
(EN)The present invention relates to a device for adjusting the curvature of a mirror by applying a bending force to or releasing the same from both ends of a mirror. According to the present invention, the device for adjusting the curvature of a mirror comprises: a base block; a pair of rotating blocks which are connected to the base block by one or more elastic bodies, respectively, and rotate or elastically return to the connection portion of the base block and the elastic bodies through application or release of an external force; a pair or support blocks which are provided at the pair of rotating blocks, respectively, to support both ends of a mirror and apply a bending force to the both ends of the mirror by rotation of the pair of rotating blocks; and an operation portion for rotating the pair of rotating blocks. The elastic bodies connect the rotating blocks to the base block in such a way such that the supporting points of the support blocks with respect to the mirror can move in the opposite direction to the moving direction of the central point of the mirror by a the change in curvature if the rotating blocks rotate. According to the present invention, the elastic bodies connecting the rotating blocks comprising support blocks to the base block are provided in such a way that the supporting points of the support blocks with respect to the mirror can move in the opposite direction to the moving direction of the central point of the mirror by the change in curvature when the curvature of the mirror is adjusted. Therefore, the movement of the central point of a mirror by the change in curvature is canceled by the movement of the supporting points placed at both ends of a mirror even if the curvature of a mirror is adjusted, and thus the absolute displacement of the central point of a mirror can be minimized, that is, the location of the central point of a mirror can be fixed when adjusting the curvature of a mirror is adjusted. In addition, since the operation portion for rotating the pair of rotating blocks to adjust the curvature of a mirror comprises a pair of transmission portions and a transfer member to enable implementation by a single operator, the adjustment of the curvature of a mirror can be conveniently progressed while controlling the input by to a single operator, and thus the adjustment of a mirror can be easily and conveniently be performed. Furthermore, the transfer force of the transfer member by the operator is applied to a pair of transmission blocks through a pair of elastic members, and thus the adjustment of the rotation angle of the rotating blocks and the adjustment of the curvature of a mirror achieved thereby can be progressed very precisely compared to the displacement of the transfer member.
(FR)La présente invention concerne un dispositif de réglage de la courbure d'un miroir consistant à appliquer une force de flexion et à la relâcher depuis les deux extrémités d'un miroir. Selon la présente invention, le dispositif de réglage de la courbure d'un miroir comprend : un bloc de base ; une paire de blocs rotatifs qui sont raccordés au bloc de base par un ou plusieurs corps élastiques, respectivement, et qui se mettent en rotation ou reviennent, de manière élastique, à la partie de raccordement du bloc de base et aux corps élastiques par l'application ou le relâchement d'une force externe ; une paire de blocs de support qui sont prévus au niveau de la paire de blocs rotatifs, respectivement, pour supporter les deux extrémités d'un miroir et appliquer une force de flexion sur les deux extrémités du miroir par la rotation de la paire de blocs rotatifs ; et une partie d'actionnement pour mettre en rotation la paire de blocs rotatifs. Les corps élastiques raccordent les blocs rotatifs au bloc de base de telle sorte que les points de support des blocs de support par rapport au miroir peuvent se déplacer dans la direction opposée à la direction de déplacement du point central du miroir par le changement de courbure si les blocs rotatifs se mettent en rotation. Selon la présente invention, les corps élastiques raccordant les blocs rotatifs comprenant les blocs de support au bloc de base sont prévus de telle sorte que les points de support des blocs de support par rapport au miroir peuvent se déplacer dans la direction opposée à la direction de déplacement du point central du miroir par le changement de courbure lorsque la courbure du miroir est réglée. Par conséquent, le déplacement du point central d'un miroir par le changement de courbure est annulé par le déplacement des points de support placés aux deux extrémités d'un miroir même si la courbure d'un miroir est réglée, et ainsi le déplacement absolu du point central d'un miroir peut être réduit, c'est-à-dire que l'emplacement du point central d'un miroir peut être fixe lorsque la courbure d'un miroir est réglée. De plus, puisque la partie d'actionnement destinée à mettre en rotation la paire de blocs rotatifs pour régler la courbure d'un miroir comprend une paire de parties de transmission et un élément de transfert pour permettre l'application par un opérateur unique, le réglage de la courbure d'un miroir peut être réalisé de manière pratique tout en contrôlant l'entrée par un opérateur unique, et ainsi le réglage d'un miroir peut être effectué de manière aisée et pratique. En outre, la force de transfert de l'élément de transfert par l'opérateur est appliquée sur une paire de blocs de transmission par le biais d'une paire d'éléments élastiques, et ainsi le réglage de l'angle de rotation des blocs rotatifs et le réglage de la courbure d'un miroir ainsi obtenus peuvent être effectués très précisément par rapport au déplacement de l'élément de transfert.
(KO)본 발명은 거울 양단에 굽힘력을 인가 또는 해제하여 곡률을 조정하는 장치에 관한 것으로서, 본 발명에 따른 거울의 곡률 조정장치는, 베이스블록; 상기 베이스블록에 하나 이상의 탄성체를 통해 각각 연결 구비되고, 외력이 인가 또는 해제됨에 따라 상기 베이스블록과 상기 탄성체의 연결부분을 중심으로 회동 또는 탄성 복귀하는 한 쌍의 회동블록; 상기 한 쌍의 회동블록에 각각 설치되어 거울의 양단을 지지하며, 상기 한 쌍의 회동블록이 회동됨에 따라 상기 거울의 양단에 굽힘력을 인가하는 한 쌍의 지지블록; 및 상기 한 쌍의 회동블록을 회동시키는 구동부;를 포함하되, 상기 탄성체는, 상기 회동블록이 회동됨에 따라 상기 거울에 대한 상기 지지블록의 지지점이 곡률 변화에 의한 상기 거울의 중심점의 이동 방향에 대해 반대 방향으로 이동될 수 있게 상기 회동블록을 상기 베이스블록에 연결한다. 본 발명에 의하면, 지지블록이 설치된 회동블록을 베이스블록에 연결하는 탄성체가, 거울의 곡률을 조정할 때에 거울에 대한 지지블록의 지지점이 곡률 변화에 의한 거울 중심점의 이동 방향에 대해 반대 방향으로 이동될 수 있게 구비됨으로써, 거울의 곡률을 조정하더라도 곡률 변화에 의한 거울 중심점의 이동이 거울 양단에 위치한 지지점의 이동으로 상쇄되어 거울 중심점의 절대적인 변위를 최소화할 수 있으므로, 즉 거울의 곡률 조정시에 거울 중심점의 위치를 고정할 수 있을 뿐만 아니라, 거울의 곡률 조정을 위해 한 쌍의 회동블록을 회동시키는 구동부가 한 쌍의 전달부와 이송부재를 구비하여 단일의 구동기로 구현되게 구비됨으로써, 거울의 곡률을 조정하는 작업을 단일의 구동기 하나에 대한 입력만 조정하면서 간편하게 진행할 수 있으므로 거울 조정 과정을 용이 간편하게 진행할 수 있고, 구동기에 의한 이송부재의 이송력이 한 쌍의 탄성부재를 통해 한 쌍의 전달블록에 각각 인가되게 구비됨으로써, 이송부재의 변위에 비해 회동블록의 회동 각도 및 이에 따른 거울의 곡률 조정을 매우 세밀하게 진행할 수 있다.
