    • A lightweight portable podium is provided for use in lectures and other speaking events. The podium rests on a table or desk and has an inclined shelf which forms the upper surface on which notes and papers can readily repose. The shelf is screened from public view and protected from wind by a main panel that forms the front of the podium and two side panels. The four pieces that comprise the podium are substantially flat and can be readily disassembled into a flat unit for storage or transit. The upper edge of the shelf is captured by two channels formed between the main and side panels. For disassembly the shelf is first pivoted to be parallel to the main panel. It is then slidden in the channels in a downward direction into contact with the main panel. The two side panels are then folded in over the shelf/main panel combination to form a flat, thin unit for storage or transit.
    • 提供轻便便携式讲台，用于讲座和其他演讲活动。 讲台位于桌子或桌子上，并有一个倾斜的架子，形成纸币和纸张可以放置在其上的上表面。 架子从公共视野进行筛选，并通过形成领奖台前面和两个侧板的主面板防风。 构成领奖台的四件大体上是平的，并且可以容易地拆卸成一个平面的单元以进行储存或运输。 搁板的上边缘由形成在主面板和侧面板之间的两个通道捕获。 为了拆卸，首先将货架枢转以平行于主面板。 然后在通道中沿着向下方向的方向与主面板接触。 然后将两个侧板折叠在搁板/主面板组合上，以形成用于存储或运输的平坦，细小的单元。

    • A ring-based sheet retainer can be removably attached to a blackboard or a presentation board. At least two sheet retainers are attached to a support member that is an elongate planar member equipped with mechanical fasteners designed to engage a complementary structure on a presentation board or the like. Each sheet retainer comprises an ring and a ring closure. The ring has the form of flattened oval: straight midportions connected by semicircular end portions. There is a gap in the midportion of the ring whereby sheets are inserted into the ring. The ring closure is a straight hollow cylinder sized to slide over the straight midportion of a gaped side of the ring. The closure is attached to the support member with an end overhanging the edge of the support member so as to receive punched sheets when the ring is open. Sliding the ring into the closure opens the ring by revealing the gap at the overhanging end of the closure. A lock bar, perpendicular to a plane of the ring, is attached to an outer edge of the ring at a point where a semicircular region of the ring interacts with the closure when the ring is open. The lock bar contacts the support member and maintains the ring perpendicular to the support member. A lock piece attached to a pivoting ring lock interacts with the lock bar when the ring is closed, thereby preventing the ring from opening until the lock is pivoted.
    • 环形片保持器可以可拆卸地附接到黑板或演示板上。 至少两个片材保持器附接到支撑构件，该支撑构件是配备有机械紧固件的细长平面构件，该机械紧固件被设计成接合表示板等上的互补结构。 每个片材保持器包括一个环和一个闭环。 环具有扁平椭圆形的形式：通过半圆形端部连接的直的中间部分。 在环的中部存在间隙，由此将片插入环中。 闭环是一个直的中空圆柱体，其尺寸设计成能够在环的空隙侧的直线中间部分上滑动。 封闭件附接到支撑构件，其端部伸出支撑构件的边缘，以便当环打开时接收穿孔的片材。 将环滑入封闭件中，通过露出封闭件悬垂端的间隙来打开环。 垂直于环的平面的锁定杆在环的外边缘处附接到环的半圆形区域，当环打开时，环的半圆形区域与闭合件相互作用。 锁定杆接触支撑构件并将环保持为垂直于支撑构件。 当环关闭时，附接到枢转环锁的锁定件与锁定杆相互作用，从而防止环打开直到锁定枢转。

    • A collapsible display easel is provided which can be easily extended into a sturdy, erect easel for holding display material, and easily retracted and folded into a compact configuration for transport. The display easel includes a two-legged supporting stand, a vertical brace, and one or more crossbar members. The display material is held against the vertical brace between the crossbar members. The legs are provided with extending support feet for securely supporting the easel in an upright position. The various components are connected by sliding or pivoting attachment mechanisms which allow the components to be easily extended or retracted. The sliding and pivoting connection mechanisms are manually operable and do not require the use of any tools or special equipment. The display easel is retracted into a compact configuration solely by pivoting or sliding the various components with respect to each other, and does not require the disassembly of any of the components. Thus, the display easel provides a sturdy, lightweight easel for displaying relatively large display materials, yet which can quickly and easily be retracted into a compact, lightweight configuration for easy transport. A carrying case is also provided.
    • 提供了可折叠的展示架，可以容易地延伸到坚固的直立画架中，用于保持显示材料，并且容易地缩回并折叠成紧凑的构造以便运输。 展示架包括双腿支撑架，垂直支架和一个或多个横梁构件。 显示材料被保持在横杆构件之间的垂直支架上。 腿部设置有延伸的支撑脚，用于将架子牢固地支撑在直立位置。 各种部件通过滑动或枢转的连接机构连接，这允许部件容易地伸展或缩回。 滑动和枢转连接机构是可手动操作的，不需要使用任何工具或特殊设备。 显示画架仅通过相对于彼此枢转或滑动各种部件而缩回到紧凑的构造中，并且不需要拆卸任何部件。 因此，显示画架提供了一种坚固，轻便的画架，用于显示相对较大的显示材料，但可以快速方便地将其缩回到紧凑，轻便的结构中，便于运输。 还提供手提箱。
