Definitions

  • the present invention relates to an improved elevator, specifically designed for civil and industrial applications.
  • an elevator or loading lowering and raising shaft comprising a plurality of ports defining the access openings at each store, a bottom end called pit as well as a top end called head, and an elevator cabin sliding on suitable sliding guides inside the elevator shaft, a gear and pulley system, as well as a machine or apparatus room, suitably arranged depending on the elevator design, and including the driving motor assembly, a control panel as well as the required electric wiring.
  • a push-button panel arranged inside the cabin allows to control the elevator cabin or load raising and lowering device up to the desired store.
  • the aim of the present invention is to overcome the above mentioned drawbacks of the prior art elevators.
  • the invention relates to an improved elevator, specifically designed for civil and industrial applications, of novel and simple construction, allowing a great saving to be achieved, as well as having a small size, together with a high reliability and a very good comfort for the users.
  • an improved elevator specifically designed for civil and industrial applications, comprising electric power supply means, load supporting means, sliding guides operatively coupled to said load supporting means and load raising and lowering means, wherein said load raising and lowering means comprise a driving assembly rigid with said load supporting means and operatively coupled to said electric power supply means.
  • the improved elevator specifically designed for civil and industrial applications according to the invention is characterized in that it has the characterizing features of Claim 1.
  • the improved elevator specifically designed for civil and industrial applications according to the invention provides the following advantages.
  • the making and operation costs thereof are small, due to a great reduction of its size and, moreover, it may be designed in a much more simple manner and with a less driving power.
  • it is possible to omit the machine room, with a consequent saving of the related cost.
  • the elevator according to the invention is much more simple than prior elevators, both of a counterweight type and of a hydraulic type.
  • the required driving power is less than that required by a prior hydraulic elevator, and this due to the specific inventive construction.
  • a further advantage is that it is possible to carry out emergency operations to arrive at the nearest floor, directly from the elevator cabin; thus, no outside operator is required for performing emergency operations.
  • the improved elevator specifically designed for civil and industrial applications, comprises a shaft 2 including a plurality of openings 3, defining the floor apertures or ports.
  • said shaft a plurality of vertical sliding guides are provided, said guides connecting an elevator cab 4 for its translation displacement.
  • Said elevator cab 4 is provided with known electric power supply connecting means, a push-button panel, a light indicator assembly, inner lamps and inner automatic or manual doors, of any known type, which will be opened synchronously with the corresponding outer doors installed at the several apertures 3 of each floor.
  • a driving assembly 5 Under the elevator can 4 a driving assembly 5 is provided, the driving motor of said assembly being specifically adapted to be controlled in its speed, by an inverter of the "VVVF" type, which is well known in the prior art.
  • the driving motor is operatively coupled, through suitable speed reducing means, to a winch 6 which is coupled by a rope 7 to a pair of pulleys 8 as well as to a further pulley 10 rigid with a counterweight 9, preferably in a size ratio 1:2.
  • a driving lever not shown, which is operatively coupled to the brake assembly of said elevator cab, in order to carry out possible manual braking emergency operations, as it will be disclosed in a more detailed manner hereinafter.
  • the ends of the mentioned rope 7 are both connected to the top of the cross member of the elevator shaft 2, at two discrete points 11 and 12.
  • the rope 7, having its first end coupled at said point 11, is downward vertically directed, and entrained on the winch drum 6 for about 180°, and then it is vertically upwardly directed up to the pulleys 8, therefrom it is directed toward the pulley 10 of the counterweight 9. After having been entrained on said pulley 10 for about 180°, it will be upwardly directed again to be connected on the top cross member of the elevator shaft 2 at the connecting point 12.
  • the rope 7 coming from the top will be entrained through about 180° on the drum of the winch 6, rigid with the elevator cab 4, and then said rope will be entrained through about 180° on a pulley rigid with the elevator cab 4, having its rotary axis parallel to the rotary axis of the winch 6 and lying on the same vertical plane, and finally being further downward directed to be fixed to the bottom end of said beam arrangement, by the above mentioned rod.
  • the counterweight would be not constitute an essential component, even if it could be provided coupled to the elevator cab 4 by a further rope and a plurality of coupling pulleys in order to reduce the working load on the driving motor.
  • the driving or motor assembly 5 as controlled by the push-button panel provided in the elevator cab 4, will actuate the winch 6 to operate the rope 7. Owing to the specifically designed rope 7 - pulley 8, 10 arrangement, and since the elevator cab 4 is connected to the driving assembly 5, the elevator cab 4 will be driven in the desired direction with a speed equal to the peripheral speed of the winch 6, whereas the counterweight 9 will be displaced in an opposite direction.
  • the upward or downward displacement of the elevator cab 4 will be very accurate and noiseless, due to the provision of the "VVVF" type of inverter, as previously mentioned, provided for controlling the rotary speed of the motor.
  • the elevator cab 4 is displaced along a rope, while sliding on its vertical guides, and holding a displacement speed equal to the peripheral speed of the winch 6.
  • a possible counterweight provided in this embodiment will reduce the operating load on the driving or motor assembly 5.
  • the user can, in both cases, operate a suitable dedicated operating lever provided on the bottom of the cab 4, to open the brake jaws.
  • the winch 6 will be rotated, thereby the elevator cab will be raised or lowered depending on the equilibrium conditions of the possibly present counterweight. In the absence of any counterweight, the elevator cab will be lowered to the nearest floor.
  • a suitable light indicator will indicate, in each case, the arriving of the elevator cab at the nearest floor, thereby signalling the success of the operation.
