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： 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： 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.

摘要： A table and improved hinge mechanism therefor. A table top (11) having extension leaves (13, 14) secured to opposite edges (15, 16) of top (11) by hinges (17, 17A, 17B, and 17C). Hinge (17) including a pivot member (20), a slide member (21), a pivot pin (22) and an extension spring (23) operate to permit extension leaves (13, 14) to be oriented in three positions, horizontal and even with the table top (11), vertically upward, and vertically downward. 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 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 support structure (10), preferably a rotatable bed, pivotable between a generally horizontal use position and a generally vertical storage position is disclosed. A counterbalancing mechanism (20) which reduces the amount of force needed to rotate the support structure (10) is operatively connected to the support structure (10). A drive arm (70) driven by a motor mechanism (64) in a linear direction is also operatively connected to the support structure (10). The drive arm (70) is connected to the support structure (10) through a linkage apparatus. The linkage apparatus has linkage plates (82) pivotably connected to drive arm (70) and connecting plates (92) extending from the support structure (10). A T-shaped rod mechanism (102) is engaged by latch (116), rotatably connected to the linkage plates (82), and extends through a hole in frame member (14) of support structure (10) where a coil spring (124) is received about the rod mechanism (102). The support structure (10) may be power rotated or manually rotated depending on whether the latch (116) is engaged or disengaged, respectively. Coil spring (124) allows movement of the support structure (10) relative to the drive arm (70) if an extraordinary force acts on the support structure (10).
