摘要:
The invention relates to a telescopic platform with rows of seats (1 to 4) which are arranged in several tiers that can be telescoped. Each tier is provided with a linear drive unit (18) for the rows of seats (1 to 4) to prevent slip.
摘要:
A seat (10) comprises a first frame (16) rotatable between a first position where the frame (16) is raised from a floor surface (4) and a second position where said frame (16) is horizontally moved down along the floor surface (4), and a second frame (17) rotatable between a raise position where the frame (17) is raised from the floor surface (4) and a folding position where the frame (17) is horizontally moved down along the floor surfaces (4) at the back of the first frame (16). The first and second frames (16, 17) are interlocked each other through arm rest (13). A seat cushion (11) is rotatably supported on the first frame (16). A back rest (12) is supported on the second frame (17) to be rotatable in back and forth directions through a pivot shaft (68a, 68b). The back rest (12) and the first frame (16) are interlocked each other through a link member (71a, 71b). The link member (71a, 71b) rotates the back rest (12) in a direction where the lower end portion of the back rest (12) is drawn forward when the first frame (16) is rotated to the first position. The back rest (12) and the arm rest (13) are rotatably supported by the second frame (17) through the common pivot shaft (68a, 68b).
摘要:
A device for automatically standing and collapsing seatings (10) mounted on floor rows (1, 2, 3) of a telescoping seating system which is adapted to be installed in a gymnasium or a multiple-purpose hall. This automatic seatings-standing and collapsing device comprises a frame (5) provided with a pair of shafts (6, 7), a rotatable supporting rod (8) whose middle portion is rotatably mounted on one (6) of the shafts (6, 7), and whose upper free tip portion is provided with a projected member (8b) adapted to be contacted with the next higher floor row, a locking lever (21) whose middle portion is rotatably mounted on the other (7) of the shafts (6, 7) and whose upper free end portion (23) is adapted to be contacted with an underside surface of the next higher floor row, while whose lower free end portion (21a) is adapted to be engaged with the lower free end (8b) of the supporting rod (8) to lock the supporting rod (8), an elastic member (24) for energizing the locking action of the locking lever (21), and a connecting means (1b, 2b, 3b, 27a) for connecting the supporting rod (8) to the floor rows (1, 2, 3).
摘要:
Salle polyvalente équipée d'un ensemble de poutres supports de sièges (1) portant des blocs porteurs indépendants (3) équipés d'un groupe de sièges (4) et pouvant être agencée selon une configuration en gradins ou selon une configuration plane, caractérisée en ce qu'elle comporte des moyens de basculement des groupes de sièges (4) constitués, pour chacun des blocs porteurs (3) par au moins un mécanisme de pantographe (9) comportant un support fixe (10) solidaire de la poutre porteuse (1) et un support mobile (11) solidaire du bloc porteur (3) et du groupe de sièges, ainsi qu'une tringlerie de commande permettant de déplacer le groupe de sièges (4) entre une position déployée et une position escamotée par rotation autour du support fixe (10).
摘要:
A seating installation concealable under the floor, the seats (1) being mounted in articulated manner, with the possibility of swivelling between a lowered, cleared-away position and a raised position of use, on pillars (3) which are fixed to the base floor (4), a number of flaps (15) being mounted in articulated manner on the same pillars (3), by means of which a raised access floor is formed under which the seats (1) may be concealed in the lowered position.
摘要:
A seat erecting/folding structure having a simple structure and a low weight and being capable of advantageously preventing, when a movable spectators' stand is to be used in a state of being developed to an intermediate stage, spectators and the like from entering an extra developed deck. In the movable spectators' stand having a plurality of decks (1, 2) capable of being nested and developed and seats (3) arranged erectably on the decks (1, 2), legs (5) of each seat (3) are hinged to a base frame (4) of the deck (1), and a bent portion of a crank member (10) provided with a swingable arm (12) projecting toward above the base frame (4) and a hook (13) projecting forward from the lower end of the swingable arm (12) is pivoted on the base frame (4), the projecting length of the swingable arm (12) is such that the distal end comes into contact with the front face (2a) of the upper deck (2), and each leg (5) is provided with a lock member (9) engageable with the hook (13) in its upright position.
摘要:
A floor apparatus (1) comprises a support base (8) and a passage base (10) rotatable about axes (11, 12) of rotation, the support base (8) providing a seat surface (13) mounting thereto seats (7) and a first selective surface (14), the passage base (10) providing a passage surface (16) and a second selective surface (15), and a rotating device (5) for rotating the support base (8) and the passage base (10) about the axes (11, 12) of rotation. The rotating device (5) is driven whereby the first selective surface (14) and the second selective surface (15) are selected and used depending upon events to improve versatility of a floor surface in accordance with the events.
