The upper frame 16 includes an upper frame base 20, a deck 22, siderails 24, and a headboard assembly 26 and a footboard assembly 28 as shown in
The footboard assembly 28 is coupled to the lower extremity support section Si and is configured to define a portion of the perimeter edge of the upper frame 16 when the person-support apparatus 10 is in the substantially planar configuration, and to be used as an egress/ingress assist device when the person-support apparatus 10 is in the chair configuration as shown in
The first footboard body 30 includes a first surface 42, a second surface 44, and a third surface 46 or footboard perimeter edge 46 extending between the first surface 42 and the second surface 44, and has a grip portion 48 and a coupling portion 50 as shown in
The pivot mechanism 34 includes a pivot joint 60, a link arm 62 or longitudinally extending member 62, and a latch mechanism 64 as shown in
The link arm 62 includes a first end 76 and a second end 78 and movably couples the first footboard body 30 to the pivot joint 60. The first end 76 is coupled to the first footboard body 30 and the second end 78 is coupled to the pivot joint 60. In one illustrative embodiment, the link arm 62 is a fixed length. In another illustrative embodiment, the link arm 62 includes a telescoping portion (not shown) configured to at least one of increase and decrease the length of the link arm 62 as shown in
The latch mechanism 64 is configured to selectively allow the first footboard body 30 to rotate with the link arm 62 between the first rotational orientation and the second rotational orientation. The latch mechanism 64 can also be configured to selectively allow the telescoping arrangement previously described above to increase/decrease in length. The latch mechanism 64 includes a handle 86, a lock 88, and a cable 90 coupled between the handle 86 and the lock 88. In one example, the handle 86 is recessed into the grip portion 48 and is configured to be depressed by a user to allow the first footboard body 30 to rotate with the link arm 62, and released to maintain the angular orientation of the first footboard body 30 and link arm 62 with respect to the lower extremity support section S1.
The lock 88 includes a spring loaded pin 92 that is configured to selectively engage one of a plurality of locating holes 68 in the cylindrical receptacle 66 of the pivot joint 60. In other embodiments, the lock 88 can be a friction lock or can be configured to selectively engage the upper frame 16. The spring loaded pin 92 is positioned in the cylindrical insert 80 and configured to extend through the lock opening 84 to engage one of the locating holes 68 to maintain the angular orientation of the first footboard body 30 and link arm 62 with respect to the lower extremity support section S1, and retract such that the spring loaded pin 92 does not engage the locating holes 68 when the first footboard body 30 and the link arm 62 are allowed to rotate about the pivot joint 60.
In operation, the first footboard body 30 and the second footboard body 32 are initially maintained in the first angular orientation along the first portion 36 of the perimeter edge of the upper frame 16. It should be appreciated that the person-support apparatus 10 can be in the substantially horizontal configuration, the chair configuration, or other configuration. The handles 86 are depressed by the user, which cause the spring loaded pins 92 to be retracted into the cylindrical insert 80 and disengage the locating holes 68. The user maintains the handles 86 in the depressed state while the first footboard body 30 and second footboard body 32 are moved with the link arms 62 between the first angular orientation and the second angular orientation. Once the first footboard body 30 and second footboard body 32 are in the second angular orientation, the user releases the handles 86, which causes the spring loaded pins 92 to extend through the lock opening 84 and engage the locating holes 68 to maintain first footboard body 30 and second footboard body 32 in the second angular orientation along the second portion 38 and third portion 40, respectively, of the perimeter edge of the upper frame 16. The person can then grip the grip portion 48 of the first footboard body 30 or second footboard body 32 to assist them when ingressing/egressing to/from the person-support apparatus.
In another illustrative embodiment, wherein like numerals indicate like features previously described, the footboard assembly 28 includes a first footboard body 30 and a second footboard body 32, a movement mechanism 134, and a latch mechanism 136. The first footboard body 30 and the second footboard body 32 are configured to selectively pivot between a first rotational orientation and a second rotational orientation with respect to the lower extremity support section S1 and translate along the lower extremity support section S1 between a first translational position and a second translational position as shown in
The first footboard body 30 is movably coupled to the lower extremity support section Si via the movement mechanism 134. The movement mechanism 134 includes a track 138 and a trolley 140 or transport 140 configured to move along the track 138 as shown in
The trolley 140 is configured to move the first footboard body 30 along the track 138 between the first translational position and the second translational position. The trolley 140 includes a rotational mechanism 152 and a transport mechanism 154. In one illustrative embodiment, the rotational mechanism 152 includes a bearing arrangement 156 that engages the shaft 160 and allows the first footboard body 32 to rotate with respect to the trolley 140. The transport mechanism 154 is configured to engage the track surface 144 and move the trolley 140 longitudinally along the track surface 144 between the first translational position and the second translational position. In one illustrative embodiment, the transport mechanism 154 is a pair of wheels configured to ride between the recessed upper track surface 144a and lower track surface 144b. In other embodiments, the transport mechanism 154 can be a slide configured to slide along the track surface 144. In other embodiments, the trolley 140 can be coupled to a gear reduction assembly (not shown) that is configured to translate the first footboard body 30 as a function of the rotation of the first footboard body 30.
The latch mechanism 136 includes a handle 86, a lock, 188, and a cable 90. In one example, the handle 86 is recessed into the grip portion 48 and is configured to be depressed by a user to allow the first footboard body 30 to rotate and translate with respect to the lower extremity support section S1, and released to maintain the rotational and translational position of the first footboard body 30 with respect to the lower extremity support section S1. The lock 188 is configured to engage the locating holes 146 to maintain the position and rotational orientation of the first footboard body 30. In one illustrative embodiment, the lock 188 includes a spring loaded pin 190 positioned within the shaft 160 of the first footboard body 30 and configured to extend from the end of the shaft 160 to engage the locating holes 146 in the track 140. In one illustrative embodiment, the spring loaded pin 190 is square and extends from the first footboard body 30 in a substantially vertical orientation. In other illustrative embodiments, the pin 190 can include a curved surface or a combination of curved and flat surfaces. The flat surface of the spring loaded pin 190 is configured to cooperate with the flat surface of the locating hole 146 to prevent the first footboard body 30 from rotating.
In operation, the first footboard body 30 and the second footboard body 32 are initially maintained in the first rotational orientation and the first translational position. It should be appreciated that the person-support apparatus 10 can be in the substantially horizontal configuration, the chair configuration, or other configuration. The handles 86 are depressed by the user, which cause the spring loaded pins 190 to be retracted and disengage the locating hole 146. The user maintains the handles 86 in the depressed state while the first footboard body 30 and second footboard body 32 are rotated between the first rotational position and the second rotational position and translated along the side of the lower extremity support section S1 between the first translational position and the second translational position. Once the first footboard body 30 and second footboard body 32 are in the second rotational orientation and the second translational position, the user releases the handles 86, which causes the spring loaded pins 190 to engage the locating holes 146 and maintain first footboard body 30 and second footboard body 32 in the second rotational orientation and the second translational position.
