Definitions

  • This invention relates to a device for standing seatings on each floor row of a telescoping seating system adapted to be installed in a multiple-purpose hall and the like.
  • a plurality of floor rows "b" provided on its upper surface with collapsible seatings “a”, and on its bottom surface with wheels “h” are so arranged as to be formed into a step-like structure.
  • a distal end of a lower wire "c” the proximal end portion of which is in turn wound around a drum "d”.
  • the seat portion, back portion and armrest portion of the seating "a” are collapsibly and pivotally mounted on a supporting rod, the lower end portion of which is rotatably mounted on the floor row "b".
  • each one of the floor rows “b” is extended to form a stepped structure, and at the same time each of the seatings "a” is automatically set to stand up by means of a standing device.
  • Another example of the prior standing device is constructed as such that an axis "i" of the supporting rod "j" pivotally supporting the seatings "a” is connected to the output axis of a motor so that the seatings can be stood up by rotating the motor in one direction, and the rotation of the motor in the other direction causes the seatings to lay down.
  • the former standing device however has defects in that it is rather complicated in structure, troublesome in assembling and adjustment, and expensive in manufacturing.
  • the latter standing device is also accompanied with problems in that since the motor is required to be mounted on each of the floor rows, it is necessary to wind up or pull out the wire cords each extending from the motors whenever the floor rows are to be extended or retracted, thus requiring a sophisticated mechanism for dealing with the wire cords. Moreover, the number of the motor has to be increased as the number of the seatings increases, thereby inevitably raising the cost.
  • a device for standing seatings mounted on each floor row of a telescoping seating system comprising a plurality of floor rows adapted to be disposed in a stepped relation, wherein when each one of the floor rows in extended forward in front of the next higher floor row, the seatings in said each one of the floor rows are set to take a standing position, and when said each one of the floor rows is retracted below the next higher floor row, the seating in said each one of the floor rows are collapsed and received within the next higher floor row, which is characterized in that said device comprises; a frame having on its backward and forward portions a pair of horizontal shafts and secured to said each one of the floor rows; a rotatable supporting rod provided on its free end with a projection adapted to be collided with a mounted portion of the seating as well as with a forward surface portion of the floor row, and on its lower end an engaging piece projecting therefrom, and pivotally mounted at the intermediate portion thereof on the shaft disposed in the forward portion of the frame;
  • reference numerals 1, 2 and 3 respectively indicate a floor row which is kept flat and provided on the underside surface thereof with wheels to run on a floor (not shown). These floor rows 1, 2 and 3 are so arranged with each other that the more forward a floor row is to be disposed, the lower the floor row becomes thereby forming a step-like structure. Although it is not indicated in the drawings, any desired number of floor rows are generally disposed in the same manner as mentioned above over the floor row 1 as well as below the floor row 3 to complete a telescoping seating system.
  • Each of these floor rows 1, 2 and 3 can be received below the next higher floor row, or extended to be disposed in a stepped relation by means of a wire having the proximal end thereof wound around a rotatable drum and the distal end thereof fixed to the foremost floor row, i.e. by winding the wire around the drum which is rotatable in both direction, or by unwinding the wire from the drum.
  • a frame 5 having a bottom plate 5a and side walls 5b fixed to both sides of the bottom plate 5a, thereby forming a U-shaped cross section is mounted on the rear portion of the surface of each floor row 1, 2 and 3. Between there side walls 5b is mounted an axis 6 piercing therethrough.
  • a frame 5c having a U-shaped cross section is mounted on the bottom plate 5a of the frame 5 and provided with an axis 7 crossing the both side walls of the frame 5c.
  • a rotatable supporting rod 8 having a U-shaped cross section and an L-shaped side wall in rotatably mounted at its corner portion (or proximal end portion) 8a on the axis 6.
  • One free end portion of the supporting rod 8 is tapered to constitute an engaging piece 8b.
  • a mounting metal member 9 having an L-shaped side surface, constituting a seat-securing means.
  • a horizontal rod 11 extending in a direction in traverse to the device is attached to the mounting metal member 9.
  • each lower end of a plurality (three or more) of supporting rods 12 kept apart equidistantly from each other.
  • the seating 10 comprising a seat portion 13, a back portion 14 and an armrest portion 15 which are constantly energized by means of a spring and the like to take a collapsed state is disposed between a pair of adjacent supporting rods 12.
  • a pair of twisted coil springs 16 and 17 are respectively inserted over the each portion of the axis 6 extending from both sides of the rotatable supporting rod 8 in order to energize the rotatable supporting rod 8.
  • tip portions 16a and 17a of each of the coil springs 16 and 17 are fixed to the proximal end portion of the engaging piece 8b of the rotatable supporting rod 8, and the other tip portions 16b and 17b thereof are fixed respectively to the side walls 5b of the frame 5.
  • the rotatable supporting rod 8 namely the seating 10
  • the seating 10 is constantly energized to take a standing posture so that when the seating 10 is being forwardly fallen down, there is little possibility that the seating 10 suddenly falls down due to its own weight.
  • the seating 10 will gradually fall down while resisting against the aforementioned energized force, thereby alleviating the shock of the falling-down.
  • a bracket 18 which is adapted to more backward and face toward the front surface of the next higher floor row when the seating 10 stands up.
  • a projection such as a roller 20 through a shaft 19 attached to and pierced in a transverse direction through the distal end portion of the bracket 18.
  • Reference numeral 21 indicates a locking lever having an open forward surface having a U-shaped section. A middle portion of the locking lever 21 is rotatably mounted on the axis 7. On the upper portion of the locking lever 21 is provided with a sliding member, namely a roller 23 rotatably mounted on a shaft 22 fixed to and piercing through the forward portion of the locking lever 21.
  • a bracket 26 having a triangular side surface is attached onto the back surface of the free end portion of the rotatable supporting rod 8.
  • a shaft 28 To this bracket 26 is mounted a shaft 28 on which a forward end portion of an engaging arm 27 having a forwardly facing look 27a on the rear end thereof is rotatably mounted.
  • a stopper 29 having a reversed L-shaped side surface is secured at its lower end to the rotatable supporting rod 8, while the upper end surface of the stopper 29 supports the engaging arm 27 to keep it at a prescribed height.
  • projections 1b, 2b and 3b which are adapted to engage respectively with the hook 27a.
  • the combination of these projections 1b, 2b and 3b, and the hooks 27a constitutes an engaging means to cause the engagement of the floor rows with the rotatable supporting rod.
  • a horizontal pin 30 is projected from the side surface of the middle portion of the rotatable supporting rod 8, and is adapted to prevent the rotatable supporting rod 8 from falling backward by colliding with stoppers 32 provided on the brackets 31 projecting inwardly from the side walls 5b of the frame 5.
  • the rotatable supporting rod 8 Since the forward end surface 1a of the floor row 1 is collided with the roller 20, the rotatable supporting rod 8 is caused to gradually fall forward while resisting the energized force of the twisted coil spring 17.
  • the roller 20 is forced to slide into the underside surface 1c from the forward end surface 1a of the floor row 1 to be pressed under the underside surface 1c, thereby causing the seating 10 to keep the collapsed horizontal state and to be vertically aligned below the highest floor row as shown in Fig. 2.
  • the seatings 10 on the floor row 3 are also collapsed and housed in the same manner as discussed above.
  • each of the floor rows 1, 2 and 3 is pulled out to cause the roller 20 to be released from being pressed under the next floor row, thereby causing the seatings 10 to become free and stand up to some extent.
  • hooks 27a are caused to engage with the projections 1b and 2b of the floor rows, thereby causing the rotatable supporting rods 8, namely the seatings 10 to stand up, and at the same time the horizontal pins 30 are disposed to be contacted to the stoppers 32 thereby to prevent the seatings 10 from tilting backward, and finishing the stand-up operation of the seatings 10.
  • the engaging piece 8b of the rotatable supporting rod 8 is caused to engage with the lower end portion of the locking lever 21 after the lower end portion of the locking lever 21 is slightly rotated backward. Therefore, the seatings are kept locked in the standing posture as shown in Fig. 1.
  • the armrest 15 is also set to become horizontal, making the seatings 10 ready for use.
  • Fig. 4 shows a second embodiment of this invention wherein the hook 27a of the engaging arm 27 employer in the first embodiment as an engaging means to stand up the seating 10 is replaced by a wire 33.
  • the same member or part as indicated in the first embodiment will be indicated by the same reference numerals thereby omitting the explanations thereof.
  • a roller 35 is rotatably mounted on a vertical shaft 34 suspended from the lower surface of a top plate 1d disposed near the front end portion of the floor row.
  • a proximal end portion 33a of the wire 33 employed as an engaging means.
  • the free end portion of the wire 33 is fixed to the bracket 18 provided at the upper end portion of the rotatable supporting rod 8.
  • This second embodiment is more simple in structure as compared with the first embodiment, and therefore advantageous in lowering the manufacturing cost thereof.
  • the engaging arm having a hook is mounted on a portion of the rotatable supporting rod located within the frame.
  • the engaging arm may be mounted outside the frame.
  • the upper end portion of the locking lever locking the rotatable supporting rod in the standing state to support the seating is adapted to slide from the forward end surface of the next higher floor row down to the underside surface of the next higher floor row.
  • the roller provided at the upper end portion of the locking lever is adapted to run along the underside surface of the next higher floor row. Therefore, the underside surface of the next higher floor row which is contacted with the roller is required to be smooth and flat in the running direction of the roller.
  • a seat-standing device wherein the locking lever can be mounted at any place without adjusting it to the position of the frame of the next higher floor row, or to the position of a reinforcing rod.
  • the roller provided at the upper end portion of the locking lever is adapted to run into a groove formed inside the next higher floor row after being collided with the forward end portion of the underside surface of the next higher floor row.
  • a stopper lever is provided below the locking lever so that when the lower end portion of the locking lever is contacted with the upper end portion of the stopper lever, any further rotation of the locking lever can be prevented.
  • Reference letters "A”, "B” and “C” shown in these Figs. 5--8 respectively indicate a floor row which is kept flat and provided on the underside surface thereof with wheels to run on a floor (not shown). These floor row A, B and C are so arranged with each other that the more forward a floor row is to be disposed, the lower the floor row becomes thereby forming a step-like structure. Although it is not indicated in the drawings, any desired number of floor rows are generally disposed in the same manner as mentioned above over the floor row A as well as below the floor row C to complete a telescoping seating system.
