Definitions

  • the present invention relates generally to ambulatory devices for individuals who have lost the use of their legs. More particularly, the invention relates to the design and construction of a prone stander having a mobile frame and an inclinable body support which allows the user to move between a vertical or standing position and a forwardly inclined position.
  • mobile prone standers To provide these additional capabilities, devices referred to as mobile prone standers have been developed. Generally, these devices comprise a mobile frame having a pair of large drive wheels similar to those seen on conventional wheelchairs. Rather than having a seat for the user, however, the mobile prone stander will include an inclinable body support frame or platform where the user is strapped in a standing position facing the body support frame. The body support frame is able to incline about an axis located relatively near the axis of the main drive wheels so that the user is able to reach the main drive wheels regardless of the position of the support frame. Thus, the user is able to move about while in the standing or any other position. Such mobile prone standers are particularly useful for developmentally disabled children who benefit from an increased ability to explore their surroundings which is unavailable with conventional wheelchairs.
  • a mobile prone stander having a body support platform where the axis of inclination is adjustable over a wide range of heights, usually being at least about 6 inches, preferably being 12 inches or greater. It would also be desirable if the design provided for a motor driven mechanism for raising and lowering the body platform which would be able to accomodate the mechanism for adjusting the height of the axis of inclination of the body support platform.
  • U.S. Patent No. 4,744,578 describes a mobile prone stander having a body platform which inclines about an axis fixed relative to the mobile frame. While the length of the body platform is adjustable, there is no mechanism provided to adjust the ground clearance to accomodate the increase in its length.
  • U.S. Patent No. 4,620,714 describes a mobile prone stander which is similar to the previously-described design in many respects, except that the position of the body support platform may be horizontally and vertically adjusted by positioning serrated plates 29 and 30 which are attached to the mobile frame. The degree of vertical adjustment, however, is very limited and the mechanical stability of the attachment appears inadequate. Moreover, the design is not amenable to motorized drive of the body platform.
  • a mobile prone stander includes improved means for attaching an inclinable body support frame to a mobile frame.
  • the mobile frame includes a pair of spaced-apart elongate frame members, and a central drive wheel is mounted on each frame member near its midpoint.
  • caster wheels will be provided at each end of the elongate frame members in order to provide stability.
  • a central housing is secured between the elongate frame members, and the manner of securing allows vertical adjustment of the housing relative to the frame members over a relatively wide distance, typically being over at least 6 inches, preferably being over at least about 12 inches.
  • the body support frame in turn, is inclinably secured to the central housing so that the axis of inclination is raised and lowered together with the housing.
  • extension of the body frame member can be accomodated with sufficient ground clearance being maintained and the user's center of gravity remaining as low as possible at all times. Keeping the axis of inclination as low as possible facilitates the user reaching the ground when the body support frame is inclined forward and provides a particularly compact profile for storage.
  • a motorized drive assembly for raising and lowering the body support frame is mounted within the central housing.
  • Such a design has the advantage that the linkage between the motorized drive and the body support frame is not disturbed when the elevation of the axis of inclination of the body support frame is adjusted.
  • Such an integrated design where the motorized drive is mounted within a housing attached to the body support frame is not found in the prior art, as discussed above.
  • the central housing is attached to the elongate frame members by a pair of cantilever plates which are removably attached at preselected, opposite angles (relative to horizontal) to the central housing.
  • the central housing may be offset downward, while with the cantilever plates oriented upward, the central housing will be raised upward.
  • the reversible cantilever plates allow the central housing to assume either of two basic configurations, i.e., a raised configuration and a lower configuration, which may be obtained simply by reversing the positions of the cantilever plates.
  • the use of an angled or canted cantilever plate is not essential to the present invention and that other designs that provide for reversible, offset mounting of the central housing will also be suitable.
  • the central housing will usually also include a plurality of vertically-spaced attachment points for the cantilever plates.
  • the spacing between the attachment points will be much less than the difference in elevation provided by reversal of the cantilever plates.
  • both gross and fine adjustment of the elevation of the housing may be achieved by selecting the orientation of the cantilever plates and by choosing which attachment points are to be utilized, respectively.
  • a continuous adjustment of the housing elevation over equal increments may be achieved.
  • knee pads are provided on the body support frame for supporting the users knees.
  • the knee pads each include a pair of contact pads which are vertically spaced-apart and which contact the user's legs just above and below the kneecap.
  • the knee pads are pivotally mounted on a universal joint so that they are self-aligning and can adjust for maximum user comfort.
  • the body support frame comprises a central shank portion, a downwardly extendible foot support portion, and an upwardly extendible chest support portion.
  • the shank portion comprises an elongate body having a pair of parallel axial bores, while both the foot support portion and the chest support portion include a pair of parallel extension members which are received in the upper and lower ends of the bores, respectively.
  • the central shank portion may be pivotally attached to the central housing using a single clevis formed on the housing.
  • a mobile prone stander 10 constructed in accordance with the principles of the present invention includes a mobile frame 12 and a body support frame 14.
  • the mobile frame 12 comprises a pair of elongate frame members 16a and 16b which are spaced-apart and which will usually be parallel to each other.
  • a central drive wheel 18 is rotatably attached to each of the elongate frame members 16 near the midpoint thereof.
  • Caster wheels 20 will be attached to each end of the elongate frame member 16, in order to provide stability for the mobile frame 12. Skids or other stabilizing mechanisms (not illustrated) might be provided in place of at least some of the caster wheels, but will generally not be preferred.
  • the elongate frame member 16 will each include a central shank portion 22, where the caster wheels 20 are mounted on extension rods 24 which are received in bores formed within the shank portion 22. In this way, the caster wheels 20 are extendible away from the shank portion 22, as best observed in Fig. 5 where an extended caster wheel is illustrated in broken line.
  • the body support frame 14 includes a central frame member 26 having a chest support 28, waist support 30, and foot support 32 mounted thereon.
  • the chest support 28 is extendible upward as indicated by arrow 34, while the foot support 32 is extendible downward as illustrated by arrow 36.
  • the central frame member 26 includes a shank portion 38 which is constructed similarly to the shank portion 22 of frame members 16.
  • the shank portion 38 includes a pair of parallel bores extending axially therethrough, with the upper end of the bores receiving a pair of rod extensions 40 and the lower end of the bores receiving a pair of rod extensions 42. All references to upper and lower made herein and in the claims will be with reference to the prone stander being in an upright orientation as illustrated in Figs. 1-3.
  • the chest support member 28 is mounted on upper rod extension members 40, while the foot support member 32 is mounted on lower rod extensions 42. In this way, the length of the body support frame 14 may be extended both by raising chest support 28 and lowering the foot support 32.
  • a pair of knee pads 48 are pivotally attached to a cross bar 50 having depending shafts 52.
  • Each knee pad includes a pair of contact pads 54 which are vertically spaced-apart and contoured to fit a user's legs just above and below the kneecap.
  • the knee pads 48 are attached to shafts 52 by a universal joint which allows full pivoting in two plane, thus providing for self-alignment of the pads to the user's knees. This construction of the knee pads has been found to provide particularly comfortable support for the user over extended periods.
  • Central housing 60 is an elongate rectangular box having a plurality of apertures formed therein to reduce its weight.
  • a clevis 62 is formed at the rear end (to the right in Figs. 3A and 3B) of the central housing 60 and receives a reinforcement sleeve 64 formed over the shank portion 38 of body support frame 4.
  • a pivot pin 66 extends through the clevis 62 and into the reinforcement sleeve 64, allowing the body support frame 14 to freely incline or rotate about the axis defined by pin 66.
  • shank portion 38 of body support frame 14 can rotate relative to the housing 60, it is not otherwise able to move relative to the housing. That is, no provisions are made for altering the position of the axis of rotation relative to the housing 60 itself.
  • the chest support 28 and foot support 32 are able to be raised and lowered, respectively, relative to the central housing.
  • the central housing 60 is provided with a vertically adjustable attachment mechanism which includes first and second cantilever plates 70 and 72.
  • Each cantilever plate 70 and 72 includes a pair of beam members 80 and a support plate 82 therebetween.
  • the cavity defined between the beams 80 may be used to mount a battery for powering a motor driven support frame inclination mechanism, as described further below.
  • the beam members 80 are detachably secured to both the central housing 60 and the shank portions 22 of the frame member 16. Conveniently, bolts or screws 90 (Fig. 4A) may be utilized. Equivalent quick attach/detach systems would also be suitable.
  • Each end of the beam members 80 is cut off at an angle which is oblique to the plane which is normal to the axis of the beam member. That is, when the beam members are secured to both the central housing 60 and the shank portions 22, they will deviate upward or downward relative to the horizontal plane between the frame members 16. As illustrated in Fig. 3A, the beam members 80 (and thus the cantilever plates 70 and 72) are directed generally downward in the direction from the frame members 22 toward the central housing 60.
  • the central housing 60 will be carried in a relatively low or downward configuration.
  • the beam members 80 (and thus the cantilever plates 70 and 72) are inclined upward in the direction from the frame members 22 toward the central housing.
  • the central housing is carried in a relatively upper or elevated configuration.
  • the central housing can be raised and lowered simply by reversing the attachment positions of the beam members 80 of the cantilever plates 70 and 72.
  • Other such reversible, offset attachment mechanisms, such as L-shaped brackets, will also be suitable.
  • Central housing 60 could be moved upward simply by unfastening the screws 90 which secure it to the attachment points 86, and resecuring the next lower set of attachment points. This would raise the pivot point 66 as illustrated by the broken line pivot point 66 in Fig. 4A. Similarly, the central housing 60 is shown in its fully upward configuration in broken line in Fig. 4A. The housing 60, however, could be incrementally lowered by moving the beam members 80 to each of the next upper attachment points 86.
  • the body support frame 14 is raised and lowered by a motorized linkage 100 which extends from the central housing 60 to a clevis or abutment 102 which is attached to the lower end of shank portion 38.
  • a tension spring 104 is provided to balance the body frame 14 and assist in raising the frame against the weight of the user. It will be appreciated that the motor and linkage 100 need not be adjusted each time the central housing is raised or lowered to effect a corresponding change in the elevation of pivot point 66. That is, the housing 60 and body support frame 14 form an integral unit whose height can be adjusted with the need to alter any of the connections between the housing 60 and the frame 14.
  • a patient will normally mount the mobile prone stander 10 with the body support frame 14 in a substantially vertical orientation.
  • the elevation of the central housing 60 may be correspondingly adjusted so that the foot support member 32 lies just above the support surface S, which may be a floor or the ground.
  • the user After mounting the body support frame 14, the user will be buckled in using the straps 110 best observed in Fig. 1.
  • the user may then employ the controller 112 to raise or lower the body support frame 14, as desired.
  • the control activates the motor drive which is housed in housing 60 and which axially translates link arm 100 to raise or lower the body support frame 14. At all times, the user is able to manually move the mobile prone stander by turning the wheels 18 in a manner similar to a conventional wheelchair.
