Definitions

  • This invention relates to lifting mechanisms.
  • this invention relates to lifting mechanisms for use in healthcare equipment such as beds.
  • the lifting mechanisms are used to raise and lower the height of the bed, i.e. increase or decrease a distance between the mattress and the floor.
  • the lifting mechanisms also allow the bed to be lowered such that the mattress is close to the floor on which the bed is standing. This has the advantage that, if a patient rolls out of the bed, they will not fall a large distance to the floor. There is, therefore, a lower, risk of injury to the patient than if the bed was at a greater height.
  • a known problem with a number of prior art mechanisms is the problem of entrapment. Because the lifting mechanisms necessarily involve moving parts, there is a risk that part of a person's body or clothing may become trapped between the moving parts, causing injury or damage. This is of particular concern for young people living with a disability or patients living with dementia.
  • a lifting assembly comprising:
  • the lifting assembly preferably further comprises tensioning means configured to apply a tensile force to the first and/or the second length of cable.
  • the tensioning means may be configured such that the same tensile force is applied to both the first and the second length of cable.
  • the tensioning means may be configured such that a different tensile force may be applied to each of the first length of cable and the second length of cable.
  • the pulley mechanism is preferably positioned at least partially within the second tubular member. This configuration also means that this part of the pulley mechanism is not exposed in use. In preferred embodiments at least a part of the first and/or the second length of cable extends through an axial bore of the second tubular member.
  • the first wheel is preferably located in a slot in the second tubular member such that a first part of the first wheel is within a bore of the second tubular member and a second part of the first wheel extends beyond an outer surface of the second tubular member.
  • the second wheel is preferably located in a slot in the second tubular member such that a first part of the second wheel is within a bore of the second tubular member and a second part of the second wheel extends beyond an outer surface of the second tubular member.
  • each of the first and second wheels are preferably mounted in a housing, with each housing being fixed to a respective end of the second tubular member.
  • the first tubular member includes an axial slot
  • the pulley mechanism is positioned at least partially within the first tubular member.
  • at least a part of the first and/or the second length of cable may extend through an axial bore of the first tubular member.
  • the second wheel preferably extends through the axial slot in the first tubular member such that a first part of the second wheel is within a bore of the first tubular member.
  • a part of each of the first and second length of cable extends along an outer surface of the second and/or the third tubular members.
  • the lifting assembly preferably further comprises a shield member attached to the second tubular member and extending over said part of each of the first and second length of cable.
  • a bed comprising:
  • each of the first and second bed ends includes two lifting mechanisms.
  • a cross member is fixed to and extends between each of the second tubular members and the actuator is connected to the cross member.
  • a cap is removeably secured to an upper end of each of the second tubular members, each cap being configured to cover a bore of the second tubular member.
  • the cap may comprise a first part releasably secured to the second tubular member and a second part releasably secured to the first part, the second part being configured to cover a means for securing the first part to the second tubular member.
  • a lifting assembly comprising:
  • each of the first and second lengths of cable may be attached to the third tubular member by tensioning means.
  • first end of each of the first and second lengths of cable may be attached to the first tubular member by tensioning means.
  • the method preferably further comprises adjusting the tensioning means to apply a tensile force to the first and second lengths of cable.
  • the step of mounting the upper wheel comprises mounting the upper wheel in a housing and securing the housing to the upper end of the second tubular member.
  • the step of securing the housing to the upper end of the second tubular member is preferably carried out after the second tubular member is located around the first tubular member and after the third tubular member is located around the second tubular member.
  • the second tubular member may include a slot at the upper end, and accordingly the method preferably comprises mounting the upper wheel such that the upper wheel extends through said slot at the upper end of the second tubular member.
  • the second tubular member may include a slot at the lower end and the first tubular member may include an axial slot.
  • the method then preferably comprises mounting the lower wheel such that the lower wheel extends through said slot at the lower end of the second tubular member and said axial slot in the first tubular member.
  • the second ends of the first and second lengths of cable are attached to an outer surface of the third tubular member.
  • first ends of the first and second lengths of cable are attached to the first tubular member in an axial bore of said first tubular member.
  • FIGs 1 to 4 show part of a bed assembly 1 according to a preferred embodiment of the present invention.
  • the bed assembly 1 comprises two bed ends 2, 4, only one of which is shown in Figures 1 to 3 , and a support 6 for a mattress extending between the bed ends 2, 4.
  • Each of the bed ends 2, 4 includes a lifting mechanism 8 that may be operated to raise and lower the mattress support 6 between a lowered position, shown in Figure 1 , in which the mattress support 6 is close to the floor, and a raised position, shown in Figure 2 , in which the mattress support 6 is at a greater distance from the floor than in the lowered position.
  • the lifting mechanism 8 comprises a telescopic post assembly 10 including three tubular members 12, 14, 16.
  • a first tubular member 12 is connected to a base 18 of the bed
  • a second tubular member 14 is connected to a headboard or footboard 20 of the bed 1
  • a third tubular member 16 is connected to the mattress support 6.
  • An actuator 22 acts on the second tubular member 14 so as to slidingly move the second tubular member 14 with respect to the first tubular member 12.
  • a pulley mechanism 24 operatively engaged with the tubular members 12, 14, 16 causes the third tubular member 16 to slidingly move with respect to the second tubular member 14.
  • both the headboard or footboard 20 and the mattress support 6 are raised with respect to the base 18 of the bed 1. Furthermore, the pulley mechanism 24 is configured such that the mattress support 6 is raised at a greater speed than the headboard or footboard 20.
  • a benefit of the combined use of an actuator 22 and pulley mechanism 24 is that the mattress support 6 may be lowered to a position very close to the ground, as shown in Figure 1 . This has the advantage that the bed may be lowered for patients that are prone to falling out of bed, so as to reduce the risk of injury to the patient if this should occur.

  • a bracket 34 is attached to the third tubular member 16.
  • the mattress support 6 is connected to this bracket 34 such that movement of the third tubular member 16 results in movement of the mattress support 6.
  • the second tubular member 14, or intermediate tubular member, extends between a first end 36 and a second end 38.
  • a first axial slot 40 is formed in a wall of the second tubular member 14 and extends from the first end 36.
  • a second axial slot 42 is formed in the wall of the second tubular member 14 and extends from the second end 38.
  • the first and second axial slots 40, 42 are sized to provide clearance for first and second wheels 56, 58 of the pulley mechanism 24. In this example the first and second slots 40, 42 are in line with each other.
  • the first tubular member 12, or inner tubular member, extends between a first end 48 and a second end 50.
  • An axial slot 52 is formed in a wall of the first tubular member 12 and extends from the first end 48 for at least substantially the whole length of the first tubular member 12. In preferred embodiments the slot 52 does not extend fully to the second end 50 of the tubular member 12 so that an end region of the tubular member 12 is a complete tube.
  • the pulley mechanism 24 comprises a first wheel 56 and a second wheel 58.
  • both of the first and second wheels 56, 58 are pulley wheels having a circumferential groove 60 in a rim 62 for receiving a cord or cable.

  • cap 148 is secured to the second tubular member 14 by means of a bolt 168, it will be appreciated that in other embodiments other suitable fastening means may be used.
  • the lifting mechanism or assembly of the present invention therefore, has a compact yet rigid structure that minimises the exposure of the pulley mechanism.
  • the assembly requires a minimal number of parts and is, therefore, relatively cost effective to manufacture, while providing important benefits in minimising the risk of entrapment and allowing, when used in a bed assembly, a large range of movement of a mattress support.
