    • A protective cover for optical means, such as binocular optical means, having a pair of exposed lens portions which are spaced apart, comprising first and second cover bodies, each having a lens cap portion for being removably secured over a lens portion of the binoculars. Each of the cover bodies has a connecting portion extending from its cap portion. An attachment means is provided for securing the connecting portions of the bodies to the binoculars at a location intermediate its lens portions. The attachment means allows movement of each of the cap portions between a first position proximate to one of the lens portions and a second position away from and intermediate the lens portion of the binoculars. The attachment means urges each of the bodies towards its second position upon being displaced therefrom, so as to avoid interfering with the binoculars when in use.
    • 用于光学装置的保护盖,例如双目光学装置,具有间隔开的一对露出的透镜部分,包括第一和第二盖体,每个具有透镜盖部分,用于可拆卸地固定在双筒望远镜的透镜部分上。 每个盖体具有从其盖部分延伸的连接部分。 提供了一种附接装置,用于将物体的连接部分固定在双筒望远镜的透镜部分的中间位置处。 附接装置允许每个盖部分在接近透镜部分之一的第一位置和远离双目镜的透镜部分的第二位置之间移动。 附接装置在从其移位时将每个主体推向其第二位置,以便在使用时避免与双筒望远镜的干涉。
