Definitions

  • articulable supports such as hospital beds
  • a support having a deck framework, a deck panel connected to the framework and a motion converter for coordinating a translational motion of the panel with rotation and/or longitudinal translation of the framework.
  • the teachings of the earlier application are presented in the context of a bed having three actuators for controlling motions of the upper body section.
  • One of these actuators controls the parallel translation.
  • the other two are operated to rotate the upper body section while concurrently translating it longitudinally, to rotate the upper body section without imparting any longitudinal translation, or to translate the upper body section longitudinally without imparting any rotation.
  • beds produced for commercial sale will include fewer actuators for the upper body section.
  • the application also describes a bed with a simplified kinematic configuration having a single upper body section actuator and a dual rack and pinion. In operation the actuator extends or retracts to translate the upper body section longitudinally while changing its angular orientation. At the same time the dual rack and pinion effects the desired parallel translation of the upper body deck panel in response to the translation and orientation of the upper body section.
  • EP 2186497 filed on November 9, 2009 and entitled "Anthropometrically Governed Occupant Support” describes an articulable support, such as a hospital bed, whose articulation depends at least in part on anthropometric considerations.
  • the application discloses a mode of operation in which rotation of a bed upper body section is accompanied by longitudinal translation of the upper body section and "parallel translation" of an upper body deck panel.
  • the application defines parallel translation as translation of the deck panel in a direction parallel to the existing angular orientation of the upper body section.
  • FIGS. 1-3 show a hospital bed 10 extending longitudinally from a head end 12 to a foot end 14 and laterally from a left side 16 to a right side 18.
  • FIGS. 1-2 also show a longitudinally extending centerline 22.
  • the bed structure includes a base frame 26 and an elevatable frame 28 connected to the base frame by folding links 30.
  • the bed also includes four deck sections: upper body section 34, seat section 36, thigh section 38 and calf section 40, all connected to the elevatable frame.
  • the upper body deck section 34 includes a framework 50 comprising left and right hollow rails 52, 54 joined to each other by an upper beam 56 and a lower beam 58.
  • First and second rail slots 60, 62 penetrate through and extend part way along the top of each rail.
  • each rail also includes a two sided mounting bracket 64.
  • the framework 50 is moveably connected to elevatable frame 28 so that the framework is longitudinally translatable relative to the elevatable frame and is also rotatable about pivot axis 70.
  • Deck section 34 also includes a deck panel 72 (shown in phantom) moveably connected to the framework 50.
  • panel 72 is translatable relative to the framework in directions P1, P2 parallel to the angular orientation ⁇ of the framework.
  • the bed also includes a pair of compression links 74 each having a frame end 76 pivotably connected to the elevatable frame at a frame joint 78 and a deck end 82 pivotably connected to the deck framework at a deck joint 84.
  • frame joint 78 is not translatable relative to the frame, however in an alternate embodiment ( FIG. 15 ) joint 78 is longitudinally translatable relative to the frame.
  • the bed also includes a drive system which includes an actuator 90 having a deck end 92 connected to upper body deck framework 50 and a grounded end 94 connected to a suitable mechanical ground, such as elevatable frame 28.
  • the drive system also includes a motion converter, indicated generally by reference numeral 100, for translating panel 72 relative to the deck framework in response to at least one of: a) relative translation between the deck framework and the frame, and b) relative rotation of the deck framework and the frame about axis 70.
  • the illustrated embodiment includes both left and right motion converter units 100L, 100R. The units are mirror images of each other, hence it will suffice to describe only one of the units in more depth.
  • FIGS. 4-8 show components and construction of one of the motion converter units in more detail.
  • the motion converter includes a gear rack 102 affixed to elevatable frame 28.
  • the gear rack may be considered to be a part of the elevatable frame.
  • the illustrated rack comprises a single piece slide rail 104 screwed to the frame and a rack plate 106 screwed to pedestals 108 at each end of the slide rail.
  • a slot 110 extends along the slide rail between the pedestals.
  • the slide rail has laterally inboard and outboard sides 112, 114 each with a shoulder 116.
  • the rack plate includes openings 120 for receiving a gear tooth. The openings have a profile that conforms to the profile of the gear teeth.
  • the motion converter also includes a primary gear 124 in mesh with the rack plate.
  • the gear has a stub shaft 126 extending laterally away from bed centerline 22.
  • a pair of lugs 128 projects laterally from the shaft.
  • a split gear housing 130 has a rectangularly shaped opening 132 extending through its base 134, a cavity 136 inside the base and a tail 138 projecting from the base. The tail nests snugly in slide rail slot 110, and the opening 132 embraces and fits snugly around rack plate 106.
  • An internal plate 140 resides in the cavity. Screws 142 extend through a bearing plate 144 and a backing plate 146 and into the internal plate 140 to slidingly clamp the housing to the slide rail with the bearing plate abutting rail shoulder 116.
  • the primary gear is rotatably mounted inside gear housing 130 by way of inboard and outboard gear bushings 154, 156 and a laterally extending pivot axle 158.
  • the pivot axle also extends through holes 162 in the rail mounting bracket 64 to connect the primary gear to the deck framework. Bearings 164 nest in the holes 162 and circumscribe pivot axle 158.
  • the motion converter also includes a deck panel rotary drive element such as a panel drive sprocket 170.
  • the sprocket resides inside a chain housing 172 located adjacent to and outboard of the gear housing 130.
  • the sprocket is rotatably mounted on pivot axle 158 by way of outboard gear bushing 156.
  • the sprocket has a stub shaft 174 extending laterally toward bed centerline 22. Notches 176 at the inboard tip of the stub shaft mate with lugs 128 on the primary gear stub shaft to rotatably connect the sprocket to the primary gear.
  • the sprocket and the primary gear are thus coaxial and mutually corotatable.
  • the pitch diameters of the primary gear and the sprocket are 37.0 and 42.6 mm respectively. Accordingly, the primary gear and sprocket exhibit a non-unity drive ratio, specifically a drive ratio of about 1.15.
  • the chain housing 172 extends into the hollow interior of the framework (i.e. into rail 52).
  • the chain housing includes an internal track or ledge 182, a shoulder 184, and an elongated slot 186 that registers with first slot 60 in the framework rail.
  • An idler sprocket 192 is rotatably mounted inside the chain housing at its remote end 194. Because the chain housing is stationary with respect to the deck framework 50, the idler can be considered to be mounted on the framework.
  • a slider 200 includes a slide link 202 translatably supported on housing internal track 182, and a slide block 204 bolted to the slide link.
  • the slide link has a ledge 206 that abuts chain housing shoulder 184 to trap the slide link in the chain housing 172.
  • the slide block includes a head portion 208 that overlies the top of framework rail 50 on either side of first rail slot 60 and a neck portion 210 that projects through the rail slot and extends to the slide link.
  • the slider also includes a drive lug 218 projecting from the slide block. The drive lug is connected to deck panel 72, thereby connecting the slider to the panel.
  • a second slider 212 comprises a second slide block 214 having a head portion 226 and a neck portion 228.
  • the second slider also includes a retainer plate 230.
  • Head portion 226 of slide block 214 overlies the top of framework rail 52 on either side of second rail slot 62.
  • Neck portion 228 projects through rail slot 62 and extends to the retainer plate.
  • the slide block and retainer plate are bolted together so that the lateral sides of the retainer plate reside under the interior of framework rail 52 on either side of second rail slot 62 and so that the slider can slide longitudinally along the length of the slot.
  • a drive lug 218 is connected to deck panel 72, thereby connecting the slider to the panel.
  • a roller chain 220 loops around each sprocket 170, 192 and engages with the sprocket teeth.
  • the ends of the chain are connected to opposite ends of the slide link 202, thereby also connecting the chain to the deck panel 72.
  • the chain is a linear or translatable drive element insofar as the part of the chain that extends linearly between the sprockets translates in direction P1 or P2 during operation of the drive system.
  • Other kinematically equivalent devices could be used in lieu of roller chain 220.
  • a lift chain one example of which is seen in FIG. 13 , could serve as a translatable drive element.
  • the primary gear is operatively connected to the deck panel 72.
  • actuator 90 extends and pushes framework beam 58 longitudinally toward the head end 12 of the bed.
  • the compression link 74 rotates clockwise to change the angular orientation ⁇ of the upper body deck framework.
  • the longitudinal translation of the framework relative to the elevatable frame causes primary gear 124 to rotate in a clockwise direction as seen in FIGS. 5 , 8 , 9 and 10 .
  • the primary gear drives the panel drive sprocket 170 in the same rotational sense.
  • the sprocket drives the chain which acts on slider 200 to translate deck panel 72 in direction P1 relative to deck framework 50. Retraction of the actuator reverses the above described motion to translate the deck panel in direction P2.
  • the kinematic interaction between the gear rack 102 and the primary gear 124 serves as a means for converting the relative translation and/or rotation between the deck framework and the elevatable frame to a rotary motion of primary gear 124.
  • the kinematic interaction between sprocket 170 and chain 220 serves as a means for converting the rotary motion to a translational motion.
  • the slider 200 and lug 218 serve as a means for conveying the translational motion of the chain to the panel.
  • FIG. 14 is a simple schematic view showing the kinematic relationship of the actuator 90, elevatable frame 28, deck framework 50 and compression link 74 of the above described bed structure.
  • Joint 78 is non-translatable relative to frame 28.
  • operation of actuator 90 causes deck panel 72 to translate longitudinally relative to the elevatable frame by a distance D and to rotate relative to the elevatable frame through an angle ⁇ .
  • joint 78 is longitudinally translatable relative to the frame by the action of second actuator 222.
  • deck framework 50 can be translated longitudinally relative to the elevatable frame 28 without any rotation of the framework ( FIG.
  • FIG. 15B rotated relative to the elevatable frame without any translation ( FIG. 15C ) or rotated and translated as in the first embodiment ( FIG. 15D ).
  • second actuator 222 introduces additional complexity, it also introduces additional flexibility that may be desirable. Because the motion converter described herein is responsive to relative motion between the frame and the deck framework irrespective of whether that relative motion is translation, rotation, or a combination thereof, it is equally applicable to the embodiments of both FIGS. 14 and 15 .
  • kinematic equivalents of various components of the motion converter can be used in lieu of the illustrated components.
  • belts and pulleys can be used instead of chain 220 and sprockets 170, 192; a notched or toothed belt and mating gears can also be substituted for the chain and sprockets; a roller and a track with a high coefficient of friction (to prevent roller skidding) might be substituted for the gear 124 and rack 102.
