It should be appreciated that the rotational axis R1 passes through the first joint 46 and the second joint 48. It should also be appreciated that the rotational axis R1 can pass through the second body 34 such that the second body 34 can be substantially symmetrical about the rotational axis R1. The grip portion 42 extends between the first end 38 and the second end 40 and is spaced apart from the second body 34 by spaces SP1 to define a pair of grips 50. The first body mount 44 is located between the grips 50 and is configured to engage a portion of the second body 34 and the body locking mechanism 36 in the first position. It should be appreciated that a portion of the first body mount 44 can be used as a grip.
The second body 34 includes a first surface 52, a second surface 54, a perimeter edge 56 extending between the first surface 52 and the second surface 54, lower stops 58, and an upper stop 60 as shown in FIGS. 1-6. The second body 34 is coupled to the movement mechanism 24 along the lower portion LP1 of the first body 32. The lower stops 58 extend from the sides of the lower portion LP1 and are configured to prevent the first body 32 from rotating to define the second position. It should be appreciated that the lower stops 58 can also be used to help reduce gaps between the siderails 20 and the endboards EB1 or adjacent siderails 20. The upper stop 60 is located along the upper portion UP1 of the first body 32 and is configured to engage the first body mount 44 of the first body 32. In one illustrative embodiment, the upper stop 60 and the first body mount 44 extend from the second body 34 and the first body 32, respectively, toward one another such that they engage one another when the first body is in the first position.
The body locking mechanism 36 is coupled to the upper stop 60 and is configured to selectively engage the first body mount 44 to maintain the first body 32 in the first position with respect to the second body 34. It should be appreciated that the lower stops 58 and/or the lower portion LP1 of the second body 34 can include a body locking mechanism 44 configured to maintain the first body 32 in the second position with respect to the second body 34. The body locking mechanism 36 includes a button 62, a spring 64, and a latch bolt 66 as shown in FIGS. 7-8. The spring 64 and the latch bolt 66 are positioned in a slot 68 in the upper stop 60. The latch bolt 66 is configured to move between a first position where the latch bolt 66 extends out of the slot 68 to engage the first body mount 44 and prevent the first body 32 from moving with respect to the second body 34, and a second position where the latch bolt 66 is retracted into the slot 68 such that the latch bolt 66 does not engage the first body mount 44 and the first body 32 is able to move with respect to the second body 34. The spring 64 is configured to bias the latch bolt 66 toward the first position. The button 62 is coupled to the upper stop 60 and includes a protrusion 70 extending from the button 62. The protrusion 70 is configured to engage a ramp 72 on the latch bolt 68 and move the latch bolt 66 from the first position toward the second position when the button 62 is pressed. It should be appreciated that the body locking mechanism 36 can include a spring (not shown) recessed into the upper stop 60 and configured to urge a sphere (not shown), such as, a ball bearing, into a recessed portion (not shown) of the first body mount 44. It should also be appreciated that the body locking mechanism 36 can be other locks, such as, for example, bolt locks, cam locks, and/or various friction locks.
In operation, the siderail 20 is initially positioned in the deployed position with the first body 32 in the first position with respect to the second body 34. The button 62 is pressed to retract the latch bolt 68 and allow the first body 30 to move with respect to the second body 34. As the first body 32 is rotated from the first position above the second body 34 to a second position below the second body 34, the height of the siderail body assembly 26 with respect to the upper frame 16 is reduced from the first height H1 to the second height H2. The change in height can help provide caregivers better access to a person supported on the person-support apparatus.
Also, in operation, the siderail 20 is initially positioned in the storage position with the first body 32 in the first position with respect to the second body 34. The button 62 is pressed to retract the latch bolt 68 and allow the first body 30 to move with respect to the second body 34. As the first body 32 is rotated from the first position above the second body 34 to a second position below the second body 34, the height of the siderail body assembly 26 with respect to the ground is reduced from the third height H3 to the fourth height H4. The change in height can help reduce incidences of the siderail body assembly 26 contacting the lower extremities of a person, such as, the underside of the person's thighs, when the person is seated along the edge of the person-support apparatus 10 and/or ingressing/egressing to/from the person-support apparatus 10.
Many other embodiments of the present disclosure are also envisioned. For example, a siderail assembly comprises a first siderail body and a second siderail body. The second siderail body is movably coupled to the first siderail body and configured to rotate between a first position and a second position with respect to the first siderail body about a rotational axis passing through the first siderail body. The second siderail body is positioned above the first siderail body in the first position and below the first siderail body in the second position.
In another example, a siderail assembly comprises a siderail body and a grip. The siderail body has an upper perimeter edge located along an upper portion of the siderail body. The grip has an upper grip edge located along the upper portion of the grip. The grip is movably coupled to the siderail body and configured to rotate between an first position and a second position with respect to the siderail body about a rotational axis. The upper grip edge is positioned above the upper perimeter edge of the siderail body in the first position and below the upper perimeter edge in the second position.
