Definitions

  • a well known kind of hoist to which this invention relates, has a transverse beam carrying a mast which supports a jib for suspending the patient.
  • the beam is carried on a pair of legs which are pivoted to the beam, and there are castors on the ends of the beam and legs.
  • the legs are connected to a lever by tie rods, and the lever can be swung to displace the legs between one extreme position in which they are close and parallel, for example for manoeuvreing the hoist along passageways, through doors etc., and a maximum splayed position when they may for example diverge about a wheelchair.
  • the positions may be indexed, that is detent engaged, and there may be intermediate positions.
  • the current industry standard arrangement for moving the legs includes a lever upstanding from the beam and generally parallel to the mast, engaged midway along its length in a gate acting as the detent mechanism, and coupled at its lower end for displacing the legs between the various positions.
  • the arrangement described has a number of disadvantages namely:-
  • the vertical lever used as the positioning handle can frequently become entangled with other parts of the mechanism such as the various cords which form a part of electrically operated hoists. This can interfere with the smooth operation of the hoist and deflect the attention of the operator away from the patient.
  • the lever used in the mechanism extends from the struts at the base generally to the waist level of the operator.
  • the length of the lever required imposes a considerable force on the linkage points at the base of the lever.
  • the force involved can lead to physical strain on the components involved and eventual mechanical failure of the parts.
  • the object of the invention is to provide improvements.
  • US-A-1 961 119 discloses a hoist according to the preamble of claim 1.
  • a pedal is mounted on an axis generally parallel to the lengths of the legs and is rockable about that axis, and the pedal is connected to the legs to displace them.
  • the pedal can be, and is indeed meant to be, foot operated. This enables the user to apply appropriate force for example by applying his/her weight to the pedal without it being necessary to relinquish the steering handles.
  • the conversion of the generally vertically directed force from the downward movement of the foot pedal to the oppositely directed horizontal forces needed to splay or converge the legs may be accomplished by providing the pedal with a pin which is normal to the length of the pedal and which is arranged to swing arcuately so that the path of the pin lies in a vertical plane, when the pedal is rocked.
  • the lower end of the pin may engage in a clevis fork provided on the lever which is coupled to the tie rods.
  • the lever which is coupled to the tie rods may be arranged so as to be pivotable simultaneously about two axes namely a first vertical pivotal axis so as to displace opposite ends of the lever in opposite directions and displace the tie rods correspondingly, and at the same time pivot in a vertical plane about one end of the lever when the other end follows the movement of the pin end.
  • This may be facilitated by making the connection between the lever and the vertical axis one where the lever is spring urged to a horizontal plane but can be displaced out of that plane during its pivotal movements.
  • the lever is provided with an indexing detent which is lifted out of engagement at the commencement of a leg adjustment and is spring returned at the completion of the adjustment.
  • the typical hoist comprises a transverse beam 10 which pivotally supports a pair of legs 12 14 which are shown in full lines in a parallel position and in dotted lines in a first diverging position.
  • the legs have castors 11 at their ends, and so does the beam.
  • the beam supports a mast 16, a pivoted jib boom 18, and a strut mechanism 20 for lifting and lowering the boom and any load such as a patient who may be seated on a structure suspended from the hooks 22.
  • the legs 12 14 are closed together to the parallel position, spread to the diverged position, and possibly spread to an even greater diverging position by means of a pair of tie rods 26 28 individually pinned to the legs, and coupled to opposite ends of a lever 30 which is pivoted between its ends on a vertical axis, and a vertically extending handle 32 is moved from side-to-side to displace that lever 30 about its pivot.
  • a gate 34 is provided to engage the handle in any one of the predetermined positions.
  • FIGs 2 to 5 illustrating the present invention, which is applied to a hoist of the same general kind comprising beam, legs and mast.
  • the beam is provided with a journal boss 30 (Fig.5) supporting a pedal shaft 31 which extends in a horizontal plane parallel to and midway between the legs 12 14 when they are parallel.
  • the pedal shaft is fixed to the pedal structure (see Figure 3), which comprises an elongated plate 36 extending generally parallel to the beam as seen in plan view and conveniently provided with pedal rubbers 38 38 for non-slip contact by a user's foot at each end of the part 36.
  • This plate 36 is located generally parallel to a tubular member 40 which may be a square section tube, seen end on in Figure 5.
  • Strut 42 is located in and extends along the tube 40 and is connected to the individual pedals by rods 43 45 which extend through apertures in the wall of the tube 40 for this purpose.
  • the strut 42 is provide centrally of its length with a drive pin 44 slidable in a guide boss 46 fixed to the lower face of the tube 40, that is the face opposite to that adjacent to the pedal structure 36 38.
  • the pin has a reduced diameter end portion 46 which, in Figures 2 and 5 is seen to be engaged in one end of operating lever 50.
  • the lever 50 is pivoted between its ends about the axis 52 and the pivot pin has a head 54 ( Figure 5) which traps a helical spring 56 between the head and the lever. This normally urges the lever to lie parallel and flat against index plate 60 which is fixed to the underside of the transverse member 10 e.g. by bolts or welding not shown.
  • Figure 5 illustrates a packing piece 62 located between the member 10 and the plate 60, but the presence or absence of such packing piece depends upon the dimensions of the other parts.
  • the index plate 60 is provided with an arcuate row of index holes 66, and the lever 50 is provided with a detent 68 for engagement in any one of those holes depending upon the position of the parts.
  • Figure 5 shows the detent disengaged from the hole due to the lever 50 being tilted against the spring, as more particularly explained hereinafter.
  • the lever 50 is connected to the respective legs 12 14 by coupling rods 70 72 which may be screw connected so as to be adjustable in length and have clevis forks at each end to allow tilting e.g. in movement of the lever to the Figure 5 position.
  • the pivot points between the legs and the transverse member 10 are indicated by the reference numerals 74, being disposed in projections from the beam.
  • the lever 52 When the legs are parallel, the lever 52 will be in one extreme angular position about pivot 52 and detent 68 will be engaged in one of the holes 66 at a one end of the row of holes.
  • the uppermost of the pedals namely 38A Figure 2
  • this pedal displacement tilts the lever 50 so as to fulcrum about its extreme end 80, i.e. the end opposite to the clevis, thereby compressing the spring 56 and at the same time taking the detent pin 68 out of its detent hole 66.
  • the displacing force also rocks the pedal about the pedal shaft journalled in the part 30 i.e. in the direction of the arrow A Figure 2 and this causes the bottom end portion 46 of the pin to move in an arc. Since the pin is engaged in the clevis fork this also serves to pivot the lever 50 about the pin 52, i.e. turn the lever angularly, and the tie rods 72 then displace the legs.
  • the action is such as to take the detent 68 from one recess 66 to the next, and in effect index the legs from the parallel position to a first diverged position.
  • the pedal structure may be generally horizontal i.e. parallel to the transverse member 10 when viewed in the Figure 2 position.
  • a repeat operation depressing the pedal 38A will result in it becoming inclined oppositely to the position seen in Figure 2 and the legs being further diverged.
  • the legs may be returned towards or to the parallel position by an almost exactly similar operation but depressing the opposite one of the pedals, resulting in the same pivotal action of the lever 50 about end 80, but opposite angular movement of the lever 50 about the pivot axis 52.
  • the spring is also effective to return the strut 42 and plate 36 to the illustrated positions relative to the tube. It will be appreciated that Figure 5 shows the pedal in the foot depressed position i.e. part-way through a leg adjustment operation.
