Benefits of technology

Enables users to rest with the seat in a convenient position and fold the device for compact storage, addressing the need for space conservation and user comfort without compromising ambulatory support.

Problems solved by technology

Certain health conditions hinder vertical balance, and movement in the upright position or other mechanics of walking.
Rollators are wheeled supports which aid individuals who have function in their lower limbs, but lack the muscular control, strength or balance to enable them to walk unassisted.

Embodiment Construction

[0011] The wheeled ambulatory support, or rollator of the present invention has a foldable frame 10 having a pair of generally U-shaped vertical side frames 12, 13 which are typically of a hollow tubular steel construction. The side frames 12, 13 each include a front leg 14, 15 and a back leg 16, 17. These front and back legs are each supported at the bottom by a wheel and at the top have an integral transverse horizontal support member 18, 19. These supports are positioned to carry armrests 20 upon which the user leans during ambulation. The supports 18, 19 also include a brake handle 21 which is used to activate a braking mechanism, typically connected by a cable to a brake shoe 24 which acts on the rear wheels 22. The rollator may also include an additional parking brake (not shown).

[0012] The front legs 14, 15 are each supported by offset castor forks 26 having a sleeve 30 that receives the bottom of the front leg and further having a front wheel 32. The back legs simply have a...

Abstract

A rollator with a tubular frame assembly includes a pair of U-shaped side frames connected by a front brace. Each side frame has a cross bar that extends between front legs and back legs of the frame. The side frames are pivotably attached to the front brace so that the side frames can fold inwardly. The rollator has a molded rigid seat that is mounted on pivot brackets to allow it to pivot upwardly out of the way of the user. The pivot brackets have an offset axis of rotation so that the seat is arranged in a curved area of the front brace when pivoted upwardly.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This is a continuation of co-pending U.S. patent application Ser. No. 09 / 977,122 filed Oct. 12, 2001, for INWARDLY FOLDING AMBULATORY DEVICE WITH AN UPWARDLY PIVOTABLE SEAT, the entire disclosure of which is fully incorporated herein by reference.[0002] The invention relates generally to wheeled ambulatory supports, and more particularly to a rollator having a molded rigid seat to allow the user to rest in a stationary position but which can be pivoted upward out of the way of the user. Further, the side frame members can be folded inwardly in order to conserve storage space. BACKGROUND OF THE INVENTION [0003] Certain health conditions hinder vertical balance, and movement in the upright position or other mechanics of walking. The health care industry has developed aids for those who suffer from such conditions, including crutches, walkers, rollators, and wheelchairs. Rollators are wheeled supports which aid individuals who have functio...
