摘要： An elevationally adjustable mobile folding stage includes two independent stage members pivotally connected for movement between an operational position and a folded storage position. Support legs are pivotally mounted to the two stage members and are pivotally connected to cross brace linkage means which interconnect the support legs and the stage members for automatically folding the legs when the stage members are pivoted to their folded position. The legs of the stage are elevationally adjustable and include roller wheels for mobility of the stage when in its folded position. A counter balance spring system is provided to assist in folding the stage.

摘要： The stage section comprises a pair of planar stage surface members hinged together for movement between a compact folded position, and an operative position. Pairs of main support legs are pivotally attached to each stage surface member so as to remain substantially vertical to support the stage in both the operative and folded positions. Castor wheel assemblies are mounted near the bottoms of the support legs, and a manually actuated mechanism is provided for controlling the retraction or extension of the wheels into ground engaging position, independently of the unfolding of the stage, so that the stage can first be unfolded, then moved precisely into the desired position before retracting the wheels to transfer the stage load to the support legs. A safety locking mechanism for stabilizing the stage in its unfolded, operative position has a lever which projects alongside the edge of the stage in its unlocked position, so as to prevent inadvertently juxtaposing a plurality of stage sections to form a large stage surface, while the sections are in their unlocked position. Telescoping support legs, and adjustable cross braces cooperate to provide great stability of the structure even at very high positions of the stage.

摘要： A drive coupling for a power operated folding support structure which is pivoted between a horizontal use position and a vertical storage position by an electric drive mechanism. A drive coupling operatively couples the arm of the electric drive motor to the pivoting support frame. The drive coupling includes a friction plate which is held between a pair of friction members secured by clamping members. The frictional drive coupling transmits force from the drive motor to pivot the frame, but allows slippage in the event that an obstacle or excessive force is encountered while pivoting the frame.

摘要： An audience control barrier for use with an elevated stage, for maintaining physical separation for performers on the stage from an audience on the other side of the barrier. The barrier is modular in form, each module including a rigid panel and brackets for supporting the panel in vertical orientation. Interconnection means on the panels permit edge to edge interconnection of modules to form a stage barrier of the desired width. According to a preferred feature, the brackets which support the panels include a top bracket having an angled flange which may be driven into wedging engagement with the top edge of the panel to hold it in place. Means are provided for interconnecting the brackets which support the panels to the legs of the stage. In a preferred form, the interconnection means comprises a hook plate configured to fit around more than half of the periphery of the stage leg, and a flipper or gate which may be moved to locking position to secure the barrier to the stage legs.

摘要： A folding ironing board including a mounting mechanism for mounting the ironing board to a wall or other support. The mounting mechanism includes pivotally connected support and control members for permitting folding movement of the ironing board between a generally horizontal use position and a generally vertical storage position adjacent the wall. Height control arms pivotally connect from the wall to the control arms and can be pivoted by releasing latch members to move the ironing board between two separate working heights, with the support members pivoting accordingly. A turntable or other pivot mounts the ironing board to the mounting mechanism to permit adjustment of angular orientation in the use position.

When in the horizontal orientation, tongue (43) is engaged within channel (35). To reorient the extension leaves, tongue (43) is withdrawn from channel (35) against the spring (23) and may be pivoted on the pin (22).

摘要： An elevationally adjustable folding stage with simplified one-man adjustment of height. The stage has two rectangular stage portions which are pivotable towards each other to a vertical storage position centered over a base frame containing main support legs. Outer support legs attached to the outer ends of the two stage members are adjustable in length. Auxiliary support legs which are longer than the main support legs are mounted to the undersides of the two stage members adjacent the main support legs. For lower stage position, the auxiliary legs are folded up, and for the higher stage position the auxiliary legs are brought to their extended position while the stage members are folded. As the stage members are brought down to their horizontal position, a rocking action about the extended auxiliary leg lifts the stage to the upper position. The auxiliary legs and outer legs are optionally extendable to another higher position. In a preferred embodiment, the auxiliary legs have a floor contact portion which extends towards the center of the stage beneath a portion of the base frame to further support the center of the stage.
摘要翻译： 一个高度可调节的折叠台，简化了一人调整的高度。 舞台具有两个矩形舞台部分，其可相对于彼此枢转到以包含主支撑腿的底座为中心的垂直存储位置。 连接到两个台架部件的外端的外部支撑腿的长度是可调整的。 比主支撑腿长的辅助支撑腿安装在邻近主支撑腿的两个台部件的下侧。 对于下阶段位置，辅助腿被折叠，并且对于较高的台阶位置，辅助腿在折叠阶段构件时被带到其延伸位置。 当舞台构件被降到水平位置时，关于延伸的辅助脚的摇摆动作将舞台提升到上部位置。 辅助腿和外腿可任选地延伸到另一较高位置。 在优选实施例中，辅助支腿具有底座接触部分，该底板接触部分在底架的一部分下方延伸到台架的中心，以进一步支撑台架的中心。
