- As previously mentioned,
mattress 12 rests onhead section 34,seat section 36, andfoot section 38 of articulateddeck 26 as shown in FIGS. 1-4. Head andseat sections deck 26 are movable to change the position of a person supported onrest surface 16 ofmattress 12.Head section 34 andseat section 36 may be rotated to change the angle of inclination of the back and thighs of the person (not shown) with respect tointermediate frame 20. Head andseat sections seat sections Foot section 38 remains generally horizontal, so that head andseat portions mattress 12 move relative to footportion 44 ofmattress 12 and relative to each other. -
Head section 34 includes a support member ordeck panel 94 and a pair ofbars 96 rigidly coupled todeck panel 94.Bars 96, and thereforepanel 94, are pivotably coupled tointermediate frame 20 by a pair ofpins 98.Seat section 36 includes a support member ordeck panel 110 and a pair ofchannel members 112 rigidly coupled todeck panel 94.Deck panel 110 is pivotably coupled tofoot section 38 by ahinge 113. - As shown in FIGS. 3 and 4,
frame 10 has a concave or recessedportion 153 defining arecess 155 configured to receivedeck panels mattress 12 during movement ofdeck sections Recess 155 provides clearance in whichdeck sections deck sections deck sections mattress 12 are positioned below portions offrame member 78. -
Frame member 78 ofintermediate frame 20 includes a pair of longitudinally extendingframe members frame members frame members frame members portions portion 153 offrame 10 andboard support portions portions board support portions Board support portions support headboard 29 andfootboard 31. According to an alternative embodiment of the disclosure, the intermediate frame includes fewer or more longitudinally extending and transversely extending frame members. - Recessed
portions recesses 141, 143 that provide clearance for the travel of head andseat sections deck sections portions widths outer width 151 of recessedportions deck 26 overhangs recessedportions intermediate frame 20. Longitudinally extendingframe members internal distance 145 that is less thanwidths deck panels frame members panels frame members outer width 151 that is less thanwidths deck panels - According to alternative embodiments of the present disclosure, other configurations of intermediate frames are provided. For example, according to one embodiment of the present disclosure, the intermediate frame is provided that is wider than the mattress and does not have recessed portions. Because the intermediate frame is wider than the mattress, the head and deck sections have enough clearance to move between the bed and chair positions. According to another alternative embodiment of the present disclosure, the deck sections are coupled to posts that elevate the deck above the intermediate frame to provided clearance for the head and deck sections during movement between the bed and seated positions.
-
Bars 96 andchannel members 112 extend beyondrespective deck panels coupler 115 as shown in FIG. 5 that couplesdeck panels Rollers 114 are provided on the distal ends ofbars 96 and are positioned to ride inchannel members 112 so that head andseat sections deck 26 are pivotably and slidably coupled together. According to an alternative embodiment of the present disclosure, the channel members are provided on the head section of the deck and the rollers are provided on the seat section of the deck. According to alterative embodiments of the present disclosure, other configurations that provide sliding and/or pivoting between the head and seat sections are possible. For example, pins in slots, tabs in channels, bearings, or any other configurations known to those of ordinary skill in the art to provide sliding and/or pivoting may be used. -
Hydraulic system 32 further includes adeck section actuator 116 pivotably coupled tohead section 34 and pivotably coupled toseat section 36 as shown in FIG. 5.Deck section actuator 116 is configured to provide power to move head andseat sections controller 33. Preferably,deck section actuator 116 is hydraulic. It will be appreciated, however, that in accordance with the present disclosure, various mechanical and electro-mechanical actuators and drivers may be used to move head andseat sections - As shown in FIG. 5,
head section 34 ofdeck 26 further includes astrut 118 rigidly coupled tobars 96 and abracket 120 rigidly coupled to strut 118. Similarly,seat section 36 includes astrut 122 rigidly coupled tochannel members 112 and abracket 124 rigidly coupled to strut 122.Deck section actuator 116 includes acylinder body 126 pivotably coupled tobracket 124 ofseat section 36 and apiston rod 128 pivotably coupled tobracket 120 ofhead section 34. - To move
rest surface 16 from the bed position, as shown in FIG. 3, to the seated position, as shown in FIG. 4,actuator 116 is extended. During this extension,piston rod 128 pushes a foot end ofhead section 34 away from a head end ofseat section 36. Becausehead section 34 is restrained bypins 98 andseat section 36 is likewise restrained byhinge 113,head section 34 pivots in aclockwise direction 130 andseat section 36 pivots in acounterclockwise direction 132. Thus, as rest surface 16 from the bed position to the seated position, a distance between the foot end ofhead section 34 and the head end ofseat section 36 increases. - Because
rollers 114 are constrained to move inchannel members 112, the angular position ofhead section 34 relative toseat section 36 is likewise constrained to follow a predetermined relationship with the extension ofcylinder 116. Thus, whendeck section actuator 116 is in the fully extended position,head section 34 is at a predetermined angle of 45° relative to the floor andseat section 36 is at a predetermined angle of 25° relative to the floor. According to alternative embodiments of the present disclosure, the head and seat sections are tilted at other angles. - To move
deck 26 back to the bed position,deck section actuator 116 is moved to the retracted position. This retraction pulls the foot end ofhead section 34 and the head end ofseat section 36 together and narrows the gap therebetween. As head andseat sections head section 34 rotates in acounterclockwise direction 134 andseat section 36 rotates in aclockwise direction 136 until both head andseat sections Actuator 116 may also be activated to move head andseat sections - As shown in FIGS. 3 and 4,
