Definitions

  • the rubbish and/or objects that have accumulated in the elevator pit have to be removed from time to time.
  • mechanics clean the elevator pit from time to time. For doing this, the elevator must be stopped, the mechanic must go into the narrow dirty pit and put the rubbish into a sack, by using his hands and/or a spade and/or a broom.
  • Normally dust, which may be inhaled by the mechanic is raised by such way of cleaning.
  • cleaning is not only unpleasant, it may even be hazardous for the mechanic, taking into account that there might be hazardous substances among the rubbish and hazardous objects such as used syringes.
  • the cleaning is time-consuming and therefore expensive.
  • a mechanic may have a tendency to refrain from doing the cleaning and to hope that the cleaning might instead be done by another mechanic when the next maintenance is due.
  • the elevator pit maintenance device may be in the form of a net that is designed to be placed in an elevator pit to cover at least a portion of the pit bottom area and to prevent objects that have larger sizes than the net openings, from falling onto the covered area of the pit bottom.
  • the maintenance net may include a net component for covering the portion of the pit bottom area and a lifting component allowing the maintenance net to be lifted by applying a lifting force to one or more lifting location(s) of the lifting component.
  • the lifting component may include a plurality of strands attached to the net component at respective attachment locations substantially at the perimeter of the net component and extending to said one or more lifting locations.
  • Fig. 1 is a perspective view of an elevator pit maintenance device placed on the bottom of an elevator pit;
  • Fig. 2 is a perspective view of the maintenance device of Fig. 1 , but in a state in which rubbish has fallen onto the maintenance device and the maintenance device has been lifted in order to remove the rubbish from the elevator pit.
  • Fig. 1 shows the pit of an elevator hoistway and in particular a pit bottom 2.
  • the lower ends of two elevator car guide rails 4 and the lower ends of two counterweight guide rails 6 stand on the bottom 2.
  • the bottom 2 is in most cases of concrete.
  • the net device 8 comprises a base (or net) component 10 and a lifting component 12.
  • the base component 10 comprises a set of parallel first strands running in a first direction and a set of parallel second strands running in a second direction that is at an angle relative to the first direction.
  • the strands define openings 14 between them which are, in the present example, square- shaped and have a size of, e.g., 5 x 5 mm.
  • the number of strand directions and the number of strands (and, therefore, the size of the openings) is variable depending on the needs of a particular device 8 embodiment.
  • the base component 10 as a whole may, as shown, have a rectangular shape, fitting - in one direction from a first wall of the elevator shaft to the opposed second wall thereof, and - in another direction - between the elevator car guide rails 4.
  • the lifting element 22 of the lifting component 12 is connected to the lateral strands 20 at the lifting location 24.
  • a free end 25 (which is shown in Fig. 1 as being close to the perimeter 18 of the base component 10) of the lifting element 22 is equipped with an engagement member 26 such as a hook (shown in Fig. 1 ), a ring 28 (shown in Fig. 2), a clasp, or other suitable member that is configured to engage a corresponding engagement member (not shown).
  • an engagement member 26 such as a hook (shown in Fig. 1 ), a ring 28 (shown in Fig. 2), a clasp, or other suitable member that is configured to engage a corresponding engagement member (not shown).
  • Such a corresponding engagement member may be, for example, positioned on the bottom of an elevator car, car frame, and/or counterweight (hereinafter collectively "car).
  • lateral strands 20 and the lifting element 22 are suitable to be used for the lateral strands 20 and the lifting element 22. Similar to the thinner strands of the net component 10, preferred materials are plastics material, fibre reinforced plastics material, strands made of fibres, metallic ropes. All materials used for the net component 10 and for the lifting component 12 may be fireproof.
  • the base component 10 will be raised substantially vertically. If, however, the lifting element 22 is engaged (directly or indirectly) to the underside of the car at a position that is closer to the door opening of the landing door from which the mechanic is accessing the pit bottom 2, the base component 10 will, when raised, swing toward the opening, thereby enhancing the mechanic's ability to reach the device 8 when the device 8 is raised to the door opening of the landing door. Regardless, the mechanic may not need to move himself into the elevator pit; in other words the mechanic can do the cleaning job while standing in the door opening of the open landing door.
  • the present invention provides the further advantage. Specifically, any liquid flowing into the elevator pit will be able to flow through the net device 8 and onto the floor of the pit bottom 2. As a result, when the device 8 is lifted by means of the car, the liquid will not be raised with the rubbish or other objects in the base component 10 of the net device 8.
  • Fig. 2 shows the situation, when the net 8 has been lifted to such an extent that it is no longer in contact with the bottom 2 of the elevator pit.
  • the provision of the lateral strands 20 has the effect that the base component 10 comes into a configuration somewhat like a sack when the device 8 is lifted.
  • the risk that rubbish or other objects fall off sideways from the base component 10 is minimized by the reinforcement 16, which helps to stabilize the base component 10 when the device 8 is lifted.
  • the device 8 in its configuration shown in Fig. 2 may be readily moved from back to front in Fig. 2 and through the open landing door. Then the device 8 may be turned upside down and emptied into a rubbish container. Thereafter, the device 8 (or a similar second device 8) may be thrown back onto the bottom 2 of the elevator shaft. Further, bar-like tools may be used to place the four corners of the base component 10 in the locations where they should be in order to re-create the situation shown in Fig. 1.
