Definitions

  • the present invention relates generally to wheel chairs and more particularly to structures or a locking fitting for coupling and locking a wheel chair component such as a leg support, an arm rest or a back rest to a frame of a wheel chair, the locking fitting having coupling means adapted to couple the wheel chair component to the wheel chair frame in such a manner that the wheel chair component may pivot to an angle relative to the wheel chair frame around a pivoting axis defined by the wheel chair frame, as well as locking means being switchable between a first position wherein the wheel chair component is locked to the wheel chair frame and a second position wherein the wheel chair component is pivotable with respect to the wheel chair frame around said pivoting axis.
  • a wheel chair component such as a leg support, an arm rest or a back rest to a frame of a wheel chair
  • the locking fitting having coupling means adapted to couple the wheel chair component to the wheel chair frame in such a manner that the wheel chair component may pivot to an angle relative to the wheel chair frame around a pivoting axis defined by the wheel chair frame,
  • a structure of this type is in this context designated a locking fitting and is to be considered as a generic term comprising not only separate fittings but also structural elements that may comprise one, two or more separate parts that can be coupled together to provide the said coupling or locking of a wheel chair component to a wheel chair frame.
  • a special application of the locking fitting according to the present invention is coupling or locking a leg support to the wheel chair frame.
  • the prior art locking fittings for use in connection with the coupling or locking of in particular leg supports to wheel chair frames only allow the leg support to swing to one of the sides which to a large extent limits the usefulness of not alone the leg support but of the entire wheel chair.
  • An example of such a prior art locking fitting is shown and described in US Patent No. 4,770,467 describing a leg support for a wheel chair.
  • the leg support comprises a pivoting arm journalled pivotably with respect to the wheel chair frame, a foot support plate being mounted in the outer free end of said arm.
  • the leg support In the normal operative position, the leg support is locked to the wheel chair frame and projects forwards from the wheel chair frame in such a manner that the person or patient sitting in the wheel chair may rest his or her feet on said plate of the leg support.
  • the leg support may as described above, e.g. when the user is to sit at a table or be moved from the wheel chair to or from a bed, be swung away and out to one side so that it is possible to guide the wheel chair in under a table or bed as described above.
  • leg support structure does not allow swinging the leg support in under the wheel chair frame and therefore, operative situations arise where the leg supports and other corresponding wheel chair components of a wheel chair that only may be swung to one side with respect to a normal operative position necessarily will be in the way for either the user or any assistant independent of whether the leg support or the corresponding wheel chair component is locked in the normal operative position or has been swung to the side.
  • this object is achieved with a locking fitting for coupling or locking a wheel chair component, particularly a leg support for a wheel chair frame
  • the locking fitting according to the invention being characterized in that the locking fitting is provided with coupling means adapted to couple the wheel chair component to the wheel chair frame in such a way that the wheel chair component can pivot to an angle with respect to the wheel chair frame around a pivoting axis defined by the wheel chair frame, and locking means being switchable between a first position wherein the wheel chair component is locked to the wheel chair frame and a second position wherein the wheel chair component is pivotable with respect to the wheel chair frame around said pivoting axis, and that the first position corresponds to a specific angular position of the wheel chair component with respect to the wheel chair frame, the wheel chair component being able to pivot from said angular position to one or the other side when the locking means have been switched to the second position.
  • the locking fitting according to the invention is, however, not only for use in connection with coupling and locking a leg support to a wheel chair frame but may furthermore e.g. be used for coupling or locking an arm rest, a back rest or some other component of a wheel chair relative to the wheel chair frame.
  • the locking fitting according to the invention may furthermore be modified such that the fitting not only exhibits one single locking position but two or more locking positions corresponding to e.g. locking a back rest in two or more positions relative to the seat of the wheel chair.
  • a wheel chair component such as a leg support should not only because of functional reasons be able to swing from one side to another in relation to the locking position but it should also advantageously be able to be dismantled or removed from the wheel chair frame to allow that the wheel chair component, when the wheel chair is constructed with a collapsible and transport-abel wheel chair frame, may be dismantled or removed from the wheel chair frame.
  • the locking means are therefore adapted to allow that the wheel chair component, particularly the leg support, may be removed from the wheel chair frame when the wheel chair component has been swung to one of the sides from said angular position.
  • the wheel chair component may accordingly not be removed from the wheel chair frame when only the locking fitting has been switched over to the other position but it can only be removed from the wheel chair frame when the wheel chair component has been swung to said one of the sides from said angular position corresponding to the first position or locking position of the locking means.
  • the locking fitting is adapted to only allow that the wheel chair component, particularly the leg support, may be removed from the wheel chair frame when the wheel chair component has been swung to one of the sides while the wheel chair component, particularly the leg support, cannot be removed from the wheel chair frame when the wheel chair component has been swung to the other position from said angular position.
  • the locking means are adapted to allow that the wheel chair component, particularly the leg support, may be removed from the wheel chair frame when the wheel chair component has been swung to one or the other side from said angular position.
  • the wheel chair component, particularly the leg support may thus be removed from the wheel chair frame if only the wheel component has been swung to one or the other side from said angular position wherein removal of the wheel chair component is prevented by the locking means.
  • the locking fitting according to the present invention particularly advantageously constitutes a locking fitting for coupling and locking a leg support to a wheel chair frame
  • the locking fitting according to the present invention may thus, as explained above, constitute one single component or a structure comprising several components cooperating to couple or lock the leg support with respect to the wheel chair frame.
  • the locking fitting is adapted to couple and lock a leg support to a vertical support tube of a wheel chair frame.
  • the locking fitting comprises a plate shaped component fixedly connected to the leg support and defining a cylinder surface constituting said coupling means and adapted to abut an outer surface of the support tube when the leg support is mounted on the wheel chair frame, the locking means comprising a locking pin fixedly connected to the support tube and arranged at a peripheral distance from said outer surface of the support tube, as well as at least two locking pawls supported by said plate shaped component and adapted to, in the first position of the locking means, project forwards from an edge of said plate shaped component and at least partly grip around said locking pin as well as being adapted to, in the second position of the locking means, be move back behind said edge of the plate shaped component so as to release the locking pawls from the engagement with the locking pin.
  • the locking fitting according to the present invention is preferably provided with an operating means which according to alternative embodiments may be constituted by a push button, a twirling knob, a thumb screw, etc.
  • the operating means is constituted by a handle allowing operation of the locking fitting and switching of the locking means from the first to the second position even for users that are physically weak and accordingly would have difficulties in exerting a pressure necessary to activate e.g. a push button, the locking pawls being movable by means of a handle between the position projecting forwards from the edge of the plate shaped component and said retracted position corresponding to the first position and second position, respectively, of the locking means.
  • the currently preferred embodiment of the locking fitting according to the present invention is furthermore preferably provided with a locking knob adapted to engage in a locking incision in the locking pin in said first position of the locking means.
  • the locking fitting according to the present invention preferably comprises a locking knob located between the locking pawls and displayed with respect to the locking pawls when viewed in the axial direction of the locking pin.
  • a second aspect of the present invention concerns a wheel chair with a wheel chair frame, two wheels connected to the wheel chair frame, a seat as well as a wheel chair component such as a leg support, an arm rest or a back rest, being pivotably mounted on the wheel chair frame and lockable with respect to same, the wheel chair frame having a locking fitting for coupling and locking the wheel chair component to the wheel chair frame, the locking fitting having coupling means adapted to couple the wheel chair component to the wheel chair frame in such a way that the wheel chair component may pivot at an angle relative to the wheel chair frame around a pivoting axis defined by the wheel chair frame, as well as locking means that may be switched between a first position wherein the wheel chair component is locked to the wheel chair frame and a second position in which the wheel chair component is pivotable with respect to the wheel chair frame around said pivoting axis, the wheel chair according to the invention being characterized in that the first position corresponds to a specific angular position of the wheel chair component with respect to the wheel chair frame, the wheel chair component being able to

  • the same locking fitting e.g. the locking fitting 40
  • the locking fitting may be used in the wheel chair for mounting the leg supports 34 and 36 with respect to the frame 12, but it is preferable from an operational point of view and for ease of use that the locking fittings be inversely symmetrical.
  • the locking fitting constructed according to the teaching of the invention alternatively may be used for pivotable but lockable fastening of e.g.
  • pivotable arm rests corresponding to the arm rests 22 and 24 in such a manner that the arm rests can be pivoted forwards and rearwards with respect to a locked central position or alternatively may be used for fastening and locking a back rest such as back rest 16 shown in Fig. 4 when the back rest is mounted pivotable with respect to the seat 14, or rather with respect to the frame 12.
  • the locking fitting according to the invention may alternatively be used in other connections with relation to wheel chairs where a pivotable conponent is used that must be able to be locked relative to the frame of the wheel chair or some other component of the wheel chair but which in certain circumstances should be able to turn to one or the other side with respect to the locked position and perhaps be released in this or those positions and perhaps be dismantled or removed from the wheel chair.
