摘要： A dual-height seat riser or booster provides an elevated seating surface for an adult individual when positioned on, for example, a bench or pew surface. The riser includes a pair of sidewalls having upper and lower edges and a seat member fixed offset to a midline so as to be closer to the upper edge of the sidewall and positioned at an angle so as to slope downward. The riser is configured such that when positioned on a bench with the lower edge of the sidewalls down and the front edge of the seat member forward, the seat member is at a first height, approximately 4 to 16 inches, and when the riser is inverted with the upper edge down and the rear edge forward, the seat member is at a second height, approximately 2 to 8 inches.

摘要： A chair (10) having adjustable height includes a seat (11) and a number of leg members (12). An adjusting mechanism (30) includes an insert sleeve (40) received within a hollow area (31) of a leg member (12). The insert sleeve (40) has an internal thread (52) which threadably receives a leg extension (60) having an external thread (61). Rotation of the leg extension (60) within the sleeve (40) adjusts the length of the leg member (12).

摘要： Lifting apparatus comprises a base, a platform disposed above the base, a thrust mechanism therebetween to lift the platform with respect to the base, and a platform stabilizer assembly enclosed within the thrust device to connect the platform and base in a fixed relationship with respect to each other. The platform stabilizer assembly comprises an upper extensible, scissors linkage mechanism having upper end portions connected to the platform and a lower extensible, scissors linkage mechanism having lower end portions connected to the base. The lower end portions of the upper extensible, scissors linkage mechanism are pivotally connected to upper end portions of the lower extensible, scissors linkage mechanism so that the scissors linkage mechanisms are constrained to move in unison. Guides located on the base and platform outside and adjacent the platform stabilizer assembly constrains movement of the stabilizer linkages within the thrust mechanism.
