Patent number: 11839576Abstract: A selectively locking rotational bearing element includes at least one bearing element supporting an outer race for rotational movement and a plurality of locking elements disposed circumferentially about an inner surface of the outer race. An actuator selectively moves the plurality of locking elements into engagement with the outer race to restrict rotational movement of the outer race and selectively move the plurality of locking elements away from engagement with the outer race such that the outer race is free to rotate relative to the locking elements.Type: GrantFiled: June 10, 2019Date of Patent: December 12, 2023Assignee: Sunrise Medical (US) LLCInventors: Samuel D. Traxinger, Jefferey Bashian

Patent number: 11382810Abstract: A personal mobility vehicle, such as a stroller, has spaced apart side frame assemblies that each include a backrest portion and a seat frame portion. The backrest portion is moveable to several recline positions relative to the seat frame portion by actuating a latching mechanism. The backrest portion and the base frame are both moveable to a folded position relative to the seat frame by actuating the same latching mechanism. The side frame assembly further has a tilt mechanism that permits the backrest and seat frames to move as a unit relative to the base frame.Type: GrantFiled: March 13, 2020Date of Patent: July 12, 2022Assignee: Sunrise Medical (US) LLCInventors: Daniel Silveira, Samuel D.

Publication number: 20220071821Abstract: A wheelchair comprises a base assembly and a tilt assembly detachably supported on the base assembly. The base assembly has a mounting point that receives the tilt assembly and a latch receiver that engages a latch assembly of the tilt assembly. The wheelchair further provides a fore and aft adjustment of a seat mounted to the tilt assembly and an angular adjustment of the seat relative to a rocker of the tilt. Each of the fore/aft seat adjustment and the seat angle adjustment relative to the rocker is independently adjustable. The rocker position of the tilt assembly relative to the base is unchanged when either the seat longitudinal position or angular position is adjusted.Type: ApplicationFiled: November 15, 2021Publication date: March 10, 2022Applicant: Sunrise Medical (US) LLCInventor: Samuel D.

Publication number: 20140084562Abstract: A wheelchair transit bracket assembly is provided and includes a clamp configured for attachment to a portion of a wheelchair frame. A pivot is attached to the clamp and is configured for rotation relative to the clamp. The pivot is configured for attachment to a tie-down assembly. The tie-down assembly is configured to secure the wheelchair to a vehicle during transit. A belt bracket is attached to the pivot and is configured for rotation relative to the pivot. The belt bracket is configured for attachment to a lap belt thereby forming a lap belt assembly. The lap belt assembly is configured to secure an occupant to the wheelchair during transit. In an installed position, the wheelchair transit bracket assembly is configured to transfer forces generated by the wheelchair and wheelchair occupant from the lap belt assembly to the tie-down assembly without introducing the forces to the wheelchair frame.Type: ApplicationFiled: September 16, 2013Publication date: March 27, 2014Applicant: SUNRISE MEDICAL (US), LLCInventors: Benjamin A.

Patent number: 8469383Abstract: A wheelchair includes a frame, and a front pivot arm pivotally mounted to the frame at a front pivot point, the front pivot arm having a caster for supporting the frame. A rear pivot arm is pivotally mounted to the frame at a rear pivot point, the rear pivot arm having a caster for supporting the frame. A ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction.Type: GrantFiled: July 3, 2012Date of Patent: June 25, 2013Assignee: Sunrise Medical (US) LLCInventors: Daniel Z. Zhou, Mark A. Jackson, John J. Tarter, Mark E. Greig, Rex W. Stevens, James M. Koerlin, Samuel D. Traxinger, Allen B. Killebrew

Patent number: 8113531Abstract: A personal mobility vehicle includes an base unit having a frame and front and rear pivot arms pivotally mounted at respective front and rear pivot points. The front and rear pivot arms support casters. A drive unit having a ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction. The base unit may also include a drive unit that is pivotally supported on the base unit by a torque arm and a suspension system that includes a suspension stop. The torque arm selectively disengages the suspension stop to allow movement of the front caster wheel in response to the terrain traversed.Type: GrantFiled: December 11, 2008Date of Patent: February 14, 2012Assignee: Sunrise Medical HHG, Inc.Inventors: Daniel Z.

Patent number: 8096570Abstract: A cable actuator comprises a housing, a handle, and a locking pin. The handle is pivotally connected to the housing and is moveable between a released position and a locked position. The handle has a slot that terminates in a locking detent. The locking pin has a first end configured to pass through the slot and a second end configured to engage the locking detent. The locking pin is biased toward engagement with the locking detent such that when the lever is pivoted to the locked position, the locking detent aligns with the locking pin permitting the second end to engage the locking detent.Type: GrantFiled: October 19, 2010Date of Patent: January 17, 2012Assignee: Sunrise Medical (US) LLCInventors: Richard E Schneider, Harlan H Hart, Samuel D Traxinger
