摘要： The removable seats system includes a number of vertically movable platforms (32) supported spacedly over ground by a ground-resting platform support and displacement device which engages the platforms and which positions the platforms in a horizontally successively adjacent although slightly horizontally spaced configuration so as to define a small horizontal gap between each two successive platforms, the platform support and displacement means further allowings selective independent vertical displacement of the platforms, the removable seats system further including a number of seat elements each associated to a coresponding platform and each including:- a row of seats (44) including at least one seat (46); and- a seat supporting structure (48) carried by a platform and supporting the row of seats. Each one of the seat members (42) is movable relative to its corresponding platform between an operative position in which the row of seats is located above its corresponding platform for allowing persons to sit on the seats, and a concealed position in which the row of seats is caried by and is located under a platform in an inoperative and concealed condition. In the operative position of each one of the seat members, the seat supporting structure extends through the gap between two successive platforms.

摘要： The linear actuator (10) comprises an elongated first band (26) wound in helical form about a central axis (11) and an elongated second flat band (36) wound on itself with its turns substantially transversely parallel to the central axis (11). The first (26) and second (36) bands are capable of taking retracted and expanded positions whereby in the retracted position the bands (26, 36) are spaced from each other. First fastening means (34) and second fastening means (40, 42) are longitudinally disposed along the first (26) and second (36) bands respectively, whereby the second fastening means (40, 42) is capable of cooperating with the first fastening means (34) to releasably interlock the first (26) and second (36) bands. Spacer means space the turns of the first band (26). Drive means cause rotation of the first (26) and second (36) bands and the spacer means about the central axis (11). Guide means (37) guide the turns of the second band (36) towards the turns of the first band (26) to interlock the first (34) and second (40, 42) fastening means.

摘要： The push actuator (10) has a fixed base (12) which rotatably carries a selectively rotatable rotor (44, 46, 48, 50). A horizontal band (24) has a lower portion stacked in a helical pattern and has an upper portion engaged by the upper portion of a vertical band (30), to form a vertical telescopic column (32). The lower portion of the vertical band (30) is stacked in a spiral, separately from the horizontal band (24), the horizontal band (24) is supported on the rotor (44, 46, 48, 50) with a helical ball support track (70) along which a number of balls (72) can roll and slide, to allow substantially frictionless rotation of the rotor member (44, 46, 48, 50) while the horizontal band (24) remains rotatably stationary. A ball re-circulation unit (76) allows the balls (72) to circulate between the top of the track (70a) and the bottom of the track (70b). Upon rotation of the rotor (44, 46, 48, 50), the vertical column (32) is formed by the horizontal band (24) being lifted and its turns being spaced through its engagement on the rotating helical ball support track (70), and by each turn of the vertical band (30) being inserted between two vertically successive turns of the horizontal band (24).

摘要： The removable seats system has a first vertically movable platform defining opposite upper and lower sides, a seat member comprising at least one seat and first and second complementary male-female engagement members respectively provided on the first platform and on the seat member. The seat member may be removably installed in an operative position on the upper side of the first platform through a releasable engagement of the first and second male-female engagement members with one another.
