The numeral 56 in FIG. 2 designates an elevator driving apparatus, the mechanism of which is as shown in FIG. 5.
chassis 57, the input axis of the said reducer 63 being connected with the axis ofan electromotor 64.
To the other axis of the electromotor 64 is fixed a V-pulley 65, the said V-pulley 65 being linked with another V-pulley 67 fixed to the axis of an emergency diesel engine provided on the chassis 56 by means of a V-belt 68, so that the grooved wheel 59 can be driven by the diesel engine 66 in case of emergency, such as power stoppage and the like, it being so arranged that the axis of the diesel engine 66 is disconnected from the V-pulley 67 by providing a clutch at the part of the V-pulley 67.
The foregoing chassis 57, as shown in FIG. 2, is provided at one side of the lower end of the tower body 11, two grooved wheels 69, 70 which are in parallel with the foregoing grooved wheel 59 being revolvably pivoted on a machinery frame 71 fixed inside the bottom of the tower body 11.
Under the foregoing counterweight 55 are fixed the upper ends of a plurality of wire ropes 72, the said wire ropes 72 being lowered perpendicularly as shown in FIG. 2, passed round the grooved wheel 69, then passed from under the said grooved wheel 69 on to the outside of the grooved wheel 59 from the upper side of the said wheel 59 through an opening 73 provided at one side of the bottom of the tower body 11, the said wire ropes 72 thus reversed being passed under the grooved wheel 69 from the lower side of the grooved wheel 59 through the opening 73, passed to the outside of the grooved wheel 70 from the lower side thereof, then guided upward along the inside of the tower body 11.
The wire ropes 72 thus guided upward is passed into the machinery room 49 through an opening 73 provided on the floorboard 51 of the machinery room 49, then passed round a pair of grooved wheels 75 revolvably pivoted by bearings 74 on the floorboard 51, the wire ropes 72 thus reversed by the respective grooved wheels 75 being guided again inside the tower body 11 through a pair of openings provided on the floorboard 51, from the lower end thereof being suspended a secondary counterweight 77 which climbs up and down inside the tower body 11.
As illustrated in FIG. 7, each three wheels 78 provided at both ends of the main counterweight 55 are maintained in contact with rails 79 provided inside the tower body 11, so that the said main counterweight 55 can climb up and down along the rails 79, guide grooves on both sides of the secondary counterweight 77 being slidably fitted to guide rails 80 provided on the main counterweight 55.
To the elevator frame 20 are concentrically fixed a plurality of power-supplying sliprings 81 which are concentrical with the rails 32, a plurality of sliding electrodes 82 (FIG. 3) provided on the rotary frame 31 being made to slide on the foregoing sliprings 81, the said electrodes 81 being connected with illuminating equipment or the like provided inside the observation room 13. Furthermore, cab tire cables for transmitting power to the sliprings 81 and the motor 38 are so distributed between the elevator frame 20 and the inside of the tower body 11 as will not interfere the elevation of the elevator frame 20, though particular description thereof is omitted here.
A plurality of posts 83 of different heights are erected on the Outside of the lower part of the tower body 11, buffer springs 84 bearing the lower side of the elevator body 12 being provided on top of the respective posts 83.
It is further so arranged that the angle of inclination of the observation room 13 and that of the platform 15 be identical so that embarkation onto the observation room 13 is possible at any position of the platform 15.
The structure of the observation tower of the invention is as described heretofore. When the grooved wheel 59 is driven by the motor 64 as illustrated in FIG. through the reducer 63 and the gears 62, 60, the wire rope 72 wound round the said grooved wheel 59 is set in motion. For instance, the rope 72 is moved as indicated by arrow in FIG. 2 and thereby the main counterweight 55 is lowered.
If the main counterweight 55 is lowered as described above, the wire ropes 48 attached to the weight 55 are lowered, the external side of the said ropes 48 which suspend the elevator frame 20 on the outside of the tower body 11 being pulled up consequently, with the result that the elevator frame 20 is elevated. At this juncture, the secondary counterweight 77 is also lowered by approximately same degree as the main counterweight 55, some disparity between both weights 55, 77 being adjusted without hindrance by the mutual sliding through the guide rails 79. The elevator frame 20 can be lowered by reversing the electromotor 64.
As described above, the elevator frame 20 is sent up and down by revolving the grooved wheel 59 by means of right and reverse revolution of the electromotor 64, as a result of which the elevator body 12 climbs up and down along the tower body 11.
If the gear 40 is turned by the electromotor 38 on the chassis of the foregoing elevator frame 20, the internal gear 36 is revolved, as a result of which the rotary frame 31 integrated therewith revolves guided by the wheels 29, 30, 35 of the elevator frame 20. Consequently, the observation room 13 too which is integrated with the rotary frame 31 revolves as it climbs up and down together with the elevator body 12. Since the rotary surface is inclined against the horizon, those sitting in the seats 44 and viewing the outside scenery through the transparent upper half 42 of the observation room 13 have an impression as if they were on an airplane making a circular ascent or descent while flying at a low altitude. The invention therefore is completely different from the simple observation tower of the conventional type.
Furthermore, when the observation room 13 is at its lowest position, it is supported by the higher springs 84 as illustrated in FIG. 2, the upper edge of the lower half 41 of the observation room 13 being slightly higher than the upper surface of the platform 15. In this state, if the lower half 41 is set free by sliding the upper half 42, it becomes possible to reach the seats 44 inside the lower half 41 from any part of the platform 15 and vice versa.
