    • A placard holding device for displaying a placard upon a vertical planar surface comprises a back frame member adapted for mounting upon the vertical planar surface and a front frame member having a flat surface portion enclosing an open window area. The front frame member is secured by a fastening assembly upon the back frame member. The fastening assembly includes a spacer member which holds the flat surface portion outwardly spaced from the back member and forms a placard holding pocket between the flat surface portion and the back frame member which is partially peripherally bounded by the spacer member. The portion of the pocket not bounded by the spacer member defines an access slot. An integral closure mechanism is provided which is operative for movement between an open position permitting passage of the placard through the access slot and a closed position preventing such passage. The device further includes an integral locking mechanism for maintaining the closure mechanism in the closed position while permitting selective movement of the closure mechanism from the closed to the open position.
    • 用于在垂直平面上显示标语牌的标牌保持装置包括适于安装在垂直平面上的后框架构件和具有包围开放窗口区域的平坦表面部分的前框架构件。 前框架构件通过紧固组件固定在后框架构件上。 紧固组件包括间隔构件,该间隔构件将平坦表面部分与背部构件向外间隔开并在平坦表面部分和后部框架构件之间形成标记保持袋,其部分地由间隔构件限定。 口袋未被间隔件限定的部分限定了一个通道槽。 提供了一种整体闭合机构,其可操作用于在允许通过通道狭槽通过标牌的打开位置和防止这种通道的关闭位置之间移动。 该装置还包括用于将闭合机构保持在关闭位置的整体锁定机构,同时允许闭合机构从关闭位置到打开位置的选择性运动。
