Definitions

  • the present invention relates to an articulating wheelchair; more particularly, but not exclusively, the invention relates to an articulating wheelchair that enables a user to perform upper and lower body exercise.
  • a user may be required to leave their wheelchair in order to use the exercise equipment properly. In such situations there may not be necessary assistance available, for example from a carer or coach, to assist the wheelchair to use the exercise equipment. Likewise, in some instances, the wheelchair user may require the need of a hoist in order to leave their wheelchair and transition to a piece of exercise apparatus or exercise equipment, as well as to return to their wheelchair.
  • US Patent US 3 268 225 discloses a hand held physical exercise device comprising a series of compression springs or other biasing means, mounted within rigid tubes against which a user had to press or pull in order to exercise. This device is one of many examples of an exercise device that is able to be used by wheelchair users.
  • hand held exercise devices provide some resistive type training and exercise for hands, arm and shoulders; and to a lesser extent torso, legs and lower body, when a user is confined to wheelchair.
  • the present invention seeks to provide a convenient way for wheelchair users to be able to perform exercise .
  • an articulating wheelchair comprising: a seat, a backrest and at least one footrest; wherein the backrest and the at least one footrest articulate with respect to the seat by means of at least a first hinge that connects the backrest to the seat, and at least a second hinge that connects the at least one footrest to the seat, thereby enabling the wheelchair to be deployed in a plurality of configurations so that a user is able to undertake exercise in a reclined state.
  • the wheelchair can be deployed in one of a plurality of configurations to enable the user to exercise different parts of their body, whilst enabling the user to be supported in the seat of the wheelchair.
  • this allows the wheelchair user to exercise more easily and now without the requirement to move from the wheelchair to a piece of exercise apparatus, such as multi-gym.
  • the seat, backrest and footrest are each defined by a framework, and the backrest and footrest are both moveable with respect to the seat.
  • the backrest and the at least one footrest pivot by means of one or more hinges with respect to the seat.
  • a user can lie back and can extend their limbs.
  • This enables a user to be partially reclined, supine and/or have one or both legs elevated whilst on the wheelchair and perform exercises whilst supported comfortably in any of these positions.
  • At least one of the hinges is adjustable and adapted to enable incremental adjustments so that the backrest and/or footrest can be configured in one of a plurality of orientations.
  • the hinges may include a ratchet or rack and pinion means to enable the backrest and/or footrest(s) to be moved to a desired position and locked in place by way of a lock means.
  • the hinges may be sprung, or incorporate a sprung mechanism, so that resistance must be applied, by the wheelchair user, in order to move the backrest and/or footrests about the hinge. In this way the user has to apply force to the backrest or footrest to generate movement or to resist movement and is thus exercising their muscles using resistance generated by the hinge.
  • the sprung mechanism may be adjustable so that the resistance can be varied to suit a user.
  • any of the aforementioned resistance devices may include a means to vary the amount of resistance they provide so that resistance can be increased or decreased.
  • the wheelchair has an arm exercise device.
  • the arm exercise device is typically an arm rest or an arm support upon which a user engages their hands or arms in order to move the arm exercise device.
  • the arm exercise device may be a pedal mechanism mounted on a support that is hingeably attached to the seat.
  • the arm exercise device has a rotating portion which offers a resistive force to turning. In this way a user can easily exercise their arms whilst sitting or lying on the wheelchair.
  • the arm device has a handle or at least one rest for each hand or arm, each handle or rest may be mounted on a crank that rotates about an axle.
  • the arm exercise device has a chain and a chainring that is driven by turning the handles or rests.
  • the chainring and chain are enclosed within a housing so that they are not accessible during normal use.
  • the support upon which the arm exercise device is mounted, is connected by a hinge to part of the frame of the wheelchair, typically the seat framework, or the support, is adapted to be received by a channel on the framework.
  • the arm exercise device can be deployed from a stowed position under the seat to a deployed position for use.
  • a user may grasp or rest upon each handle and turn the cranks about the axle, or move the chain about the chainring when seated, on the seat, or whilst lying, to exercise their arms.
  • the arm mechanism may have a means to assist movement, such as a motor to turn the handles. In this way a user’s arms may be moved, even if they do not have the strength to turn the arm exercise device manually. This may have therapeutic benefits to improve muscle tone and assist in circulation.
  • the wheelchair has a pair of independently movable footrests, one for each foot. In this way a user can exercise each leg separately.
  • the backrest has a resistance mechanism, for example being sprung, so as to require force to move the backrest from a first upright position to one or more second reclined positions and so that when released the backrest is bias to return to the first position.
  • a resistance mechanism for example being sprung, so as to require force to move the backrest from a first upright position to one or more second reclined positions and so that when released the backrest is bias to return to the first position.
  • the at least one footrest may have a resistance mechanism, such as a spring or gas strut, so as to require force to move one or both footrests between a standard seated position (where a user’s knees are bent and feet are facing downwards), to one or more extended positions in which a user’s feet are raised. It is appreciated that movement in one direction may encounter resistance and movement in the other direction may be biased to return more easily.
  • a resistance mechanism such as a spring or gas strut
  • a user is able to select which direction of movement has resistance and which direction is bias to return.
  • a user can choose to exercise and engage different leg muscles by either applying force with their leg to move the footrest, or by using their leg to resist the bias sprung mechanism.
  • an adjuster for varying the resistance of the mechanism is provided for easy access by the user, so that a user can adjust the resistance to match their ability.
