Definitions

  • the present patent of invention refers to a swing hoist for lifting loads, which is provided with means for extending the swing hoist arm.
  • hoists that, in general, are arranged between the floor and the ceiling of a room and near a window, or even on a balcony, so as to stretch an arm, which is provided with lifting means, out of a parapet of a balcony or a window-sill.
  • the above mentioned hoisting apparatuses present an inconvenience, that is when a balcony is not provided with an upper counterceiling, the hoist must be mounted inside the flat and in this case, the arm bearing the lifting motor does not present the features necessary for permitting the hoist itself to be employed when there are intermediate obstacles to overcome.
  • the solution of the aforecited problem is proposed by the present invention, which permits a swing hoist to be mounted inside a room looking on to a balcony, this swing hoist being able to get over the door window, directed outwards, and the parapet so as to go out of the balcony itself.
  • the device according to the present invention By employing the device according to the present invention, it is still possible to easily lift loads from a balcony, even when the balcony is not provided with an upper clasping support for the swing hoist such as a counterceiling or the like so as to make the loading and unloading of the objects to be shifted vertically easier.
  • the invention relates to a swing hoist for lifting loads, which is provided with means for extending its arm, characterized in that the said means consists of a particularly shaped prolongation to be arranged between the fixed support of the swing hoist and the swing arm bearing the motor; the said extension can also co-operate with a perforated tube to be inserted, if necessary, for raising the height of the swing arm in respect of the extension itself; means for mechanically lifting the said arm being also provided.
  • number 1 indicates a swing hoist according to the invention as a whole, which swing hoist consists in general of a vertical pole 2 comprehending an inner telescopic tube 3 which can be extended by means of a manual small winch 4, operated through a handle 5, till reaching the wished height so as to touch the ceiling.
  • a coupling collar 6, adjustable in height, is mounted on the telescopic tube 3.
  • An arm 7 for supporting the motor can be directly mounted on the collar 6 in normal conditions of use. In fact, the said arm is provided with holes 8 which can be inserted in projections 9 provided on the coupling collar 6.
  • the swing hoist When it is necessary to prolong the length of the arm itself, the swing hoist must be equipped with an extension 10 so that the swing hoist itself shows for instance a structure as represented in Figg. 1 and 2.
  • the extension 10 is in general formed by a parallelepiped-shaped framework, provided with diagonal reinforcements 11 and coupling seats 12 and 13, opposite to each other.
  • the first coupling seats 12 have to be inserted in the projections 9 whereas the second ones 13 house the arm 7 and hold the arm itself through its seats 8.
  • a perforated tube 14 can be inserted, as shown in Fig. 3.
  • the inserted perforated tube 14 consists in general of a structural, provided with a series of longitudinal holes 15 which are to be inserted in the outer coupling seats 13 of the extension 10, and coupling projections 16 which can house the arm 7 through its holes 8.
  • the perforated coupling parts 8, 9, 12, 13, 15 and 16, of the arm 7, the collar 6, the extension 10 and the tube 14 respectively can be crossed by pins or the like for blocking a part into another.
  • the pole 2 is arranged between a floor and a ceiling by acting on the small winch 4 which draws a rope 17 lifting the telescopic tube 3 through a transmission.
  • the arm 7 can be directly mounted on the projections 9 of the collar 6 by centering the holes 8 into the projections 9. Otherwise, in the aforecited particular conditions, the extension 10 is intercalated so as to insert and block the holes 12 of the extension itself in the projections 9.
  • the arm 7 is mounted on the extension 10 by inserting the holes 8 in the coupling seats 13.
  • the perforated tube 14 can be mounted on the extension 10 by inserting the suitable holes 15 in the coupling seats 13 whereas on the other side, the projections 16 can house the holes 8 of the arm 7.
  • the arm 7 without the lifting group 18 can be mounted on the relative supports with a particular kind of lifting by means of a further rope 17′, moved through the same winch 4.
  • the small winch 4 has the double function of raising the telescopic tube 3 towards the ceiling by means of the rope 17 and raising the arm 7 and its operating means through the rope 17′.
  • the small winch 4 operates the drawing of the rope 17′ which is fixed on the motor 18 when the motor is still in its container.
  • the motor By acting on the same handle 5, the motor recovers the space of the telescopic part 20 of the arm 7, the telescopic part 20 being operated by an inner pressure spring.
  • the motor When the motor has closed the telescopic space, the arm begins to raise till inserting the upper point 8 in one of the coupling parts 9, 13 or 16. The whole is locked by means of pins or the like.
  • the telescopic part 20 can be moved inside or outside the arm in opposition with the pressed spring by reversing the direction of rotation of the small winch 4 and acting on the handle 5.
  • the motor 18 is driven electrically through a push-button panel "rise-descent" and comprises a lifting rope 21 which can be rewinded on a drum 22 arranged on a horizontal axis.
  • a drum comprises lips of transmission which permit a good rewinding and unwinding of the rope 21 itself.
