Definitions

  • a lift cage for instance as a result of a power cut off, stops in an intermediate position between two stories authorized personnel can open an appropriate story door in the lift shaft as well as the door of the lift cage in order to evacuate persons that have been travelling with the lift. If this takes place downwards, that is the opened shaft door is below the lift cage the evacuated persons must be prevented from falling in under the lift cage itself and down into the lift shaft, which is achieved by a ridged cage guard extending downwards from the floor of the lift cage and sufficiently far down in order to eliminate the risk that anybody falls in under the lift cage.
  • a ridged cage guard extending downwards from the floor of the lift cage and sufficiently far down in order to eliminate the risk that anybody falls in under the lift cage.
  • the invention has as its object to provide a solution to this problem and enable lift installations without lift pit with a retaining of a safe cage guard function.
  • this object is solved by the guard being articulated to the floor of the lift cage in order to allow a folding of the cage guard against bottom side of the floor of the lift cage. Furthermore a guide for the cage guard is arranged along the lift shaft preventing guard from being swung into the shaft anywhere but close to the bottom position, that is when the lift cage is getting close to the bottom of the shaft. Here it is of no importance if the guard is swung in below the bottom of the lift cage since there is no drop inside the shaft.
  • the swinging in of the guard may for instance be achieved by the same guide that controls the guard during the movement higher up in the shaft curving inward forcibly controlling the lower end of the guard inward towards the middle of the lift cage so that when the lift cage reach the bottom the guard lays flat below bottom of the cage. Since the guard only has to be a few millimeters thick in order to fulfill its function the required increased height of the bottom position of the lift is only a few millimeters. Although it is prescribed that the guard in its lower end has to have a bending at the edge this may be located between supporting beams in the lift bottom.
  • the control may preferably include a ball bearing that with a bolt is connected to the guard and a guide rail fastened to the shaft wall and enclosing the ball bearing. The rail may then curve inward more or less along a quarter of a circle to achieve the swing in movement also by means of the guide and the roller.
  • the guard device according to the invention is very reliable and dependable since it is completely mechanical and the guard is efficiently constrained. Furthermore the device is very easy to check since it is sufficient to look and grip it to decide if it is functioning or not. The device is strong and takes at the same time extremely little space in the bottom position. If the control from one reason or the other should fail the guard will when elevator gets closer to the bottom be deformed more or less and cause the lift to stop, which then only can occur with the lift close to its bottom position at which the security system of the elevator existing for other reasons will be activated in this extremely unlikely incidence.
  • Fig 1 a lift shaft with an accompanying lift cage in a lateral view with one shaft wall removed
  • fig 2 shows a detail of fig 1
  • fig 3 shows the lift shaft in fig 1 with the cage lowered somewhat further
  • fig 4 a detail from fig 3 in a larger scale
  • fig 5 the lift shaft in a lateral view with the lift cage in its most lowered position
  • fig 6 an enlargement of a detail in fig 5.
  • the lift shown in the drawings includes a shaft 1 in which a lift cage 2 is movably vertically. From the lift cage a guard 3 extends vertically downwards on the side where the doors are arranged. The guard 3 is in its upper end via a piano hinge articulated to the lower edge of the bottom of the lift cage. In the lower end the guard is provided with a laterally protruding bolt, on which a ball-bearing is arranged, which ball-bering runs inside a control rail 4 that runs vertically in the shaft but for the bottom end of the shaft, where the guide rail turns of in towards the middle of the shaft where control guide curves inward towards the center of the shaft in a soft bend that then finnish in a horizontal section close to the bottom of the lift shaft.
  • the guard functions so that it by the guide is held vertical but when the lift comes close to its bottom position where the lower guide (the ball bearing) follows the control guide as is shown in fig 3 and 4.
  • the cage guard lies flat below the cage.
