Abstract

An ambulatory assist apparatus is configured to be mounted to a frame of a bed. The ambulatory assist apparatus includes an ambulatory assist arm having a first end portion and a second end portion configured to provide a handle, a mounting plate configured to be coupled to the frame of the bed, and a pivot pin for pivotably coupling the ambulatory assist arm to the mounting plate. The mounting plate includes a plurality of spaced-apart apertures. The apparatus also includes a locking pin coupled to the first end portion of the assist arm. The locking pin is configured to engage a selected one of the plurality of apertures in the mounting plate to secure the ambulatory assist arm at different orientations relative to the mounting plate. The apparatus further includes an actuator to release the locking pin from the selected aperture to permit pivotable movement of the ambulatory assist arm relative to the mounting plate.

an actuator to release the locking pin from the selected aperture to permit pivotable movement of the ambulatory assist arm relative to the mounting plate, and

first and second mounting bars coupled to the mounting plate, the mounting bars being configured to be inserted into mounting tubes coupled to the frame of the bed.

9. The apparatus of claim 8, wherein the mounting tubes are also configured to receive first and second siderail mounting bars to couple a siderail to the frame when the assist arm apparatus is removed.

10. A patient support comprising:

a frame including first and second spaced-apart mounting tubes,

a mattress positioned on the frame and defining a patient rest surface,

a bed accessory including an accessory member configured to move between a raised position above the patient rest surface and a lowered position, a position adjustment mechanism coupled to the accessory member to permit movement of the accessory member between the raised and lowered positions, and first and second spaced-apart mounting bars coupled to the position adjustment mechanism and positioned in the first and second mounting tubes of the frame, the position adjustment mechanism including a mounting plate coupled to the first and second mounting bars, a pivot pin configured to pivotably couple the accessory member to the mounting plate, and a lock, the mounting plate including at least one aperture, the lock being configured to engage the at least one aperture in the mounting plate to position the accessory member at first orientation relative to the mounting plate.

11. The patient support of claim 10, wherein the first and second mounting tubes extend transverse to a longitudinal axis of the frame.
