Definitions

  • This invention relates to mobility aids.
  • This invention has particular but not exclusive application to mobility aids for use by people with greatly reduced mobility, eg quadriplegics, stroke patients and patients with other forms of paralysis. It will therefore be convenient to hereinafter describe the invention with reference to this example application. However it is to be clearly understood that it is capable of broader application.
  • Walking sticks and frames are provided to assist impaired mobility people to move about.
  • open wheeled walking frames are provided which support the forearms of a user for providing stability such that they may walk without assistance from another person.
  • These contrivances are designed to assist people to walk and move around generally, ie to aid translational mobility. However they do not assist in lifting a person from a seated or lying position to a standing position and vice versa.
  • Special chairs are also provided for persons with mobility restrictions which act to slowly elevate the seated person towards the standing position when the user commences to elevate themselves from the seat.
  • Other forms of assistance are also provided such as fixed elevated hand holds.
  • a disadvantage of the existing arrangements is that mobility impaired persons are restricted as to their choice of seating unless they are assisted to and from conventional seating by another person.
  • the present invention aims to alleviate at least some of the abovementioned disadvantages and to provide a mobility aid which will assist all these movements .
  • a mobility aid for assisting up/down and translational mobility of a user
  • the aid including: a wheeled base assembly having a front portion which extends in use across in front of a user and also leg portions extending rearwardly along opposing sides of user; a support member projecting up from the base assembly; vertically moveable upper body support means mounted on said support member for supporting upper limbs of the user; and drive means for selectively raising and lowering the upper body support means to thereby assist in lifting and lowering the body of the user.
  • the support means can be raised on demand to lift a patient to a standing position, eg from a seated position on any chair.
  • the support means can also be lowered to lower a patient to a seated position on a bed or chair.
  • the upper body support means comprises a cross shaft and left and right hand side upper body support members mounted on said cross shaft, and each said left and right hand side support member has a forearm support and a hand grip.
  • the forearm support is in the form of an open channel formation or a saddle and the hand grip is in the form of an upwardly projecting handle bar around which the hand grips.
  • the cross shaft is directly mounted on the support member, eg towards an upper end thereof.
  • the support member includes a tubular member and an extensible shaft which is received within said tubular member, the extensible shaft moving telescopically with reference to the tubular member.
  • the tubular member is mounted to the base assembly and the extensible shaft is positioned above the tubular member and attached to the upper body support means towards its upper end.
  • the tubular member and extensible shaft may have complementary screw thread formations thereon for engaging each other and effecting axial movement relative to each other by rotation relative to each other. More specifically the extensible shaft may have an external screw thread formation thereon and the tube may define an internal bore having a screw thread which is rotationally fixed relative to the tube and which engages the external screw thread on the shaft.
  • the drive means may comprise an electric motor driveably coupled to the shaft to rotate the shaft which is energised by an electrical supply, and a control for switching the electric motor on and off and causing the motor to rotate in two different directions.
  • the electric motor is a direct current electric motor mounted on the base assembly and the electrical supply includes at least one rechargeable battery mounted on the base assembly.
  • the battery may be rechargeable by simply electrically connecting it to a domestic mains electrical socket.
  • the support member may include a tubular member and a hydraulic ram which is movably received within the tubular member and the drive means may comprise a hydraulic circuit including hydraulic pump for effecting extension/retraction of the hydraulic ram.
  • the extensible shaft may be driven by a chain and sprocket or rack and gear arrangement.
  • the control may be a hand control associated with the upper body support means and which is operated by the user of the aid, eg a push button control mounted on one of the hand grips.
  • the aid may further include means for adjusting the spacing of the left and right hand side upper body support members on the cross shaft.
  • the spacing adjusting means comprises sleeves associated with the left and right hand side upper body support members through which the cross shaft passes, and means for locking the left and right hand side upper body support members in a desired position along the length of the cross shaft. That way the left and right hand side support members can be broadly aligned with the user's shoulders to provide the most comfortable spacing thereof.
  • the hand grips are positioned broadly at the intersection of the cross shaft with the left and right hand side upper body support members.
  • the mobility aid may further include crutches for positioning under the left and right hand side armpits of a user which are removably mounted to the left and right hand side upper body support members and project upwardly therefrom. Naturally the aid may also include means for adjusting the height of the crutches. The crutches may be removable or detachable from the aid when they are not required.
  • the aid may further include a lower body support for supporting a posterior abdominal region of a user, eg a user's bottom.
  • the support may include a flexible support suspended from the left and right hand side support members of the upper body support means and which in use is passed under the posterior abdominal region of a user.
  • the support is in the form of an adjustable seat harness or a sling.
  • the left hand and right hand side upper body support members include anchoring formations for suspending the harness or sling therefrom, eg in the form of rings or lugs.
  • the sling or harness provides an uplift to the user's lower body when the vertically movable support means is elevated. This is helpful in raising them to the standing position when they have a weakened upper body. Without the sling the user is required to brace their arms during elevation. The idea is that the aid should reduce the effort required by the user as much as possible and this feature assists in achieving this objective.
  • the aid has one said support member which is substantially centrally positioned with reference to the base assembly and the body of a user.
  • One advantage of this is simplicity of structure.
  • the aid has two laterally spaced support members extending up from the base assembly.

  • the adjusting means includes means for moving said left and right hand side upper body support members vertically with respect to the central support member and locking means for locking the extendible shaft in a selected vertical position.
  • the locking means may come in any one of a variety of well known arrangements and will not be described further in this specification.
  • the left and right hand side upper body support members be set at a height which suits that particular user.
  • the user should be able to reach the control when in a seated position on a chair before being raised by the aid.
  • the left and right hand side upper body support members should also be in a convenient position when the user is in a standing position and using the aid to stabilise their upright position while they are moving around.
  • the height of people varies greatly and the aid needs to adjust for these height differences so that the left and right hand side upper body support members are at a convenient and comfortable vertical position when the extendible shaft is both fully extended and fully retracted.
