Patent number: 11642260Abstract: A system for changing width of a person support apparatus is disclosed. A person support apparatus comprises at least one deck extension which is configured to be retracted or extended by at least one motor controlled by a bed controller. A mattress controller communicates with a bed controller and controls a fluid supply device to inflate or deflate a mattress supported by the person support apparatus to alter the width of the mattress. The mattress may also be inflated or deflated in response to manual extension or retraction of the deck extension.Type: GrantFiled: August 9, 2013Date of Patent: May 9, 2023Assignee: Hill-Rom Services, Inc.Inventors: Mahesh Kumar Thodupunuri, Jeffrey A.

Patent number: 9925102Abstract: A system for changing the width of a person support apparatus includes a bed controller for receiving a command signal indicating a command for width alteration, a first motor controlled by the bed controller for driving an extension of a first deck section of the support apparatus thereby altering the width of the first deck section, and a second motor controlled by the bed controller for driving an extension of a second deck section of the support apparatus thereby altering the width of the second deck section. The bed controller controls the first motor and the second motor in a manner that causes the first deck section to reach a first deck section width alteration limit at a first time and the second deck section to reach a second deck section width alteration limit at a second time, wherein the first time and the second time are not equal.Type: GrantFiled: May 24, 2017Date of Patent: March 27, 2018Inventors: Jonathan D. Turner, John D. Christie, Joseph A. Ernst, David P. Lubbers, Scott M. Corbin, Mark E. Lanning, Mahesh Kumar Thodupunuri, Aziz Ali Bhai

Patent number: 9757293Abstract: A bed comprises a deck section having a width and left and right outboard deck edges. Left side and right side wings are movably coupled to the deck section. The bed also includes a left leadscrew receiver mounted on the left wing, a right leadscrew receiver mounted on the right wing, and left and right motor assemblies both mounted on the deck section. A left leadscrew is coupled to the left motor assembly and to the left leadscrew receiver. A right leadscrew is coupled to the right motor assembly and to the right leadscrew receiver. Motor operation is capable of moving the wing to which it is coupled between a deployed position in which the lateral extremity of the wing is outboard of the respective outboard edge of the deck section and a stored position in which the lateral extremity of the wing is inboard of its deployed position.Type: GrantFiled: November 20, 2014Date of Patent: September 12, 2017Assignee: Hill-Rom Services, Inc.Inventors: Jonathan D.
