Description
- The present invention relates to a rolling walker, and more particularly to a rolling walker which can be can be temporarily converted to a transportation chair.
- Rolling walkers or wheeled walkers are widely used by elderly people and/or other people experiencing difficulty walking without a walking aid. A rolling walker typically has a frame mounted on four rollers or wheels and a pair of rearwardly extending hand grips to be gripped by the user for support while walking. Rolling walkers permit the user to be positioned behind the hand grips and to push and roll the walker forward over the ground. Rolling walkers usually include a seating surface to allow the user to rest in a sitting position with the user's feet typically resting on the ground, which requires the user to turn around and sit down in a rearward-facing direction, opposite to the direction of travel. Such a sitting position of the rolling walker cannot be used to temporarily transport the user when the assistance of a care-giver is required because there is very little space between the user and the care giver when the user is seated in the rearward facing position between the hand grips. Furthermore, the conventional rolling walker does not have dedicated feet support elements which are required to support the user's feet when seated for transportation.
- Therefore, there is a need for a rolling walker which provides the functionality of assisting people in walking and is temporarily convertible to a wheeled transportation chair.
- One object of the present invention is to provide a rolling walker which is temporarily convertible to a wheeled transportation chair.

Means are provided for rolling the walker device along a support surface. A seat is attached to the frame structure and extends between the front legs and between the rear legs. A detachable backrest is adapted to be selectively attached to the front legs in a front position or to the rear legs in a rear position.
- In accordance with another aspect of the present invention, a walker device for assisting an individual with mobility and convertible to a transportation chair comprises a frame structure supported on rotatable wheels, including two front legs in a substantially parallel relationship, each having an upper end and a lower end thereof, two rear legs in a substantially parallel relationship, each having an upper end and a lower end, the rear legs being connected at the upper end thereof to the respective front legs. A seat attached to the frame structure extends between the front legs and between the rear legs. A backrest is attached to the frame structure and is adapted to be selectively disposed in a front position for a rearward seating condition or in a rear position for a forward seating condition. A footrest assembly is attached to the frame structure and is adapted to pivot about parallel first and second pivoting axes, between a folded position and an unfolded position.

FIGS. 7 and 8 . Thehinge device 70 includes a pair ofhinge elements lower end 18 of onefront leg 14 and thesecond end 66 of onearm 64 and rotatable relative to each other about abolt 703 which extends through central holes defined in thehinge elements front leg 14. Each of thehinge elements flat end surface member members hinge elements members members flat end surface FIG. 8 is limited to about 120°. - It should be noted that any desirable pivoting range can be obtained by choosing the circumferential dimensions of the protruding
members footrest assembly 58 pivotable between the desired orientations (the folded and unfolded positions as shown in the respectiveFIGS. 1 and 2 ) the circumferential position of the respective protrudingmembers front legs 18 andarms 64, orarms 64 and theU-shaped footrest bar 72. - In operation, the
frame structure 12 is fully extended from its collapsed storage condition to form a stable A-shaped configuration which can be pushed and rolled on the ground or other support surfaces. When thewalker device 10 is used as a roller walker for assisting an individual while walking, thebackrest 52 is placed in the front position and thefootrest assembly 58 is disposed in the folded position and is secured to thecloth bag 43, as shown inFIG. 1 . Optionally, thebackrest 52 can be removed from theframe structure 12 entirely, if desired. The user grips thegrip portions 46 of the hand grips 44 and pushes thewalker device 10 on the support surface while therebehind. When the user wishes to rest, the user can press the lever assemblies to brake therear wheels 30. Thelever assemblies 48 preferably has the function to lock the braking condition. After therear wheels 30 are locked in the braked condition, the user can turn around and sit on theseat 42 facing rearwardly. The user can lean against thebackrest 52 which is placed in the front position. - When the
walker device 10 is temporarily used as a wheeled transportation chair, thebackrest 52 is detached from thebrackets 38 and thearms 56 thereof are then inserted into thebrackets 40 on therear legs 20, thereby forming the rear position of thebackrest 52. Theupper portion 54 of thebackrest 52 extends between the twohand grips 44 behind theseat 42, as illustrated inFIG. 2 . Thestrap fastener 76 on thecloth bag 43 is released to allow thefootrest assembly 58 to be pivoted about the respective pivoting axes 60, 62 from the folded position (shown inFIG. 1 ) to the unfolded position (seeFIG. 2 ). In the unfolded position, theU-shaped footrest bar 72 is suspended downwardly from the forwardly extendingarms 64, and is spaced apart from the support surface. Thefootrest assembly 58 is prevented from pivoting far enough to cause contact between the U-shaped footrest bar and the ground surface, by the axial protrudingmembers hinge device 70 and/or by thecross member 32 which prevents the further pivoting motion of thearms 64 about the pivotingaxis 60. The user can then be seated on theseat 42 facing forwardly, with his/her feet resting on theU-shaped footrest bar 72, and thewalker device 10 which is now temporarily converted to a wheeled transportation chair can be pushed and rolled on the ground or other support surfaces by a caregiver who walks behind thewalker device 10. - The above description is meant to be exemplary only and one skilled in the art will recognize that changes may be made to the embodiments described without departure from the scope of the invention disclosed. For example, the present invention can be applicable to a walker device having a frame structure different from the described frame structure, such as one which is not collapsible, and/or not presenting a general A-shaped configuration. The hand grips, brake system and wheels may be configured differently from those of the described embodiments and the cloth bag is optional. Still other modifications which fall within the scope of the present invention will be apparent to those skilled in the art in light of a review of this disclosure, and such modifications are intended to fall within the appended claims.
