Definitions

  • This invention relates to portable or transportable hoists primarily but not exclusively for domestic use in invalid or patient care.
  • the usual design comprises a wheeled chassis, a mast upstanding from the chassis, a boom extending outwardly from the mast, and winch means for raising or lowering a chair, sling or other carrying means.
  • the hoist may be used for example to lift a patient in or out of a bath.
  • the problem is that the hoist occupies a substantial space which is particularly inconvenient at times when it is not actually in use. Its volume also makes it difficult to manoeuvre through doorways and upstairs so that for example storage in a outhouse or garage, and return to the place of use only when needed is not a satisfactory option.
  • the invention aims to solve this problem.
  • a hoist comprises a wheeled chassis, a mast, a boom, and a winch, and is characterised in that the mast is hinged and arranged to fold to a collapsed position on the chassis.
  • the carrying means which are to be raised or lowered may be in fixed position on the boom, and in this case the winch may pivot the boom on the mast: or the boom may be a normally fixed lateral extension of the mast and not intended to pivot during hoisting operations and in such case the winch may be connected to the carrying means by a cable which depends from the end of the boom.
  • the invention provides a hoist which, in preferred embodiments, can be collapsed to a relatively small cross section bundle, which can be suitably dimensioned to go in a car boot, under a bed, or in a wardrobe for example.
  • the hoist comprises a chassis 10 with wheels 12 14, a mast 16, boom 18 20, winch 22, and cable or other flexible tie 24 26 28.
  • FIGS 5 and 6 show the chassis in more detail. It comprises a base plate 30 carrying a socket 32 shown separately in Figure 4, and legs 34 36 which may be telescopically extendable to the illustrated position, and/or pivotally mounted on the base plate to allow them to be spread for stability or moved parallel to one another and close together, or perhaps detached from the base plate for such purposes so as to make the stored bundle even more compact.
  • the legs may carry castor wheels 14 at their free ends.
  • Wheels 14 may be on inclined stub axles 40, as shown, in the interests of stability. These axles may be fixed to the base plate. Any one or more of the wheels may be braked.
  • the boom comprises a bracket portion 48 pivoted to the mast, and offset limbs 18 20. Stop means not shown may prevent the boom moving anticlockwise relative to the mast from the Figure 1 position. However the boom is, in this embodiment, free to move clockwise, under the control of the cable 24 28, which extends about pulleys, and the winch 22. Extending the cable 24 by clockwise winch movement lowers the end 50 and, subject to the mentioned stop means, vice versa.
  • a seat or other carrying means may be fixedly suspended at the end 50 and raised and lowered by use of the winch pivoting the boom.
  • the winch may have a geared system to enable even a child or weak person to raise and lower loads, and preferably also brake means or a so-called overspeed governor to control the speed of raising and more especially of lowering, to prevent the load falling out of control.
  • the winch may have a ratchet action and be operated from an upwardly extending reciprocable lever to avoid a user having to bend down to reach the winch.
  • it may be a power operated winch connected to any suitable power source such as a nearby mains electric power socket by a cable, and operable by a hand-held controller.
  • the boom may be folded to the Figure 2 position, and of course this folding operation is only done when the seat is unoccupied and perhaps detached from the boom.
  • Socket 42 is mounted on the base plate, and is used to mount the mast.
  • the mast has a cross pin 44 running in slots 46 in the socket, and the latter includes an aperture receiving the extreme lower end of the mast when in the Figure 1 and Figure 4 position. So the socket and pin together hold the mast upright. In this position, hinging of the mast is impossible.
  • To hinge the mast it is lifted slightly, for example by a handle 60 manually manipulated, to free the extreme end from the aperture and take the pin towards the opposite end of the slots. This action will normally be accomplished after first folding the boom to the Figure 2 position.
  • the bundle may be fastened by a strap or like encircling the chassis, mast and boom. In the folded condition the bundle can be trailed using the wheels at either end, but usually by towing with wheels 12 engaging the ground.
  • Handle 60 is also intended for use for steering and guidance of the erected hoist and for this purpose projects laterally as a pair of handlebars as shown in Figure 6.
