As best illustrated in FIGS. 1 through 5, the collapsable walker 10 generally comprises a base assembly 12 that has perimeter wall 14. The base assembly 12 is substantially hollow. The base assembly 12 substantially encircles a user. A plurality of wheels 16 is operationally coupled to a lower end 18 of the base assembly 12. The plurality of wheels 16 facilitating rolling the base assembly 12 along a horizontal support surface such as a floor. A hand hold portion 20 is operationally coupled to an upper end 22 of the base assembly 12. The hand hold portion 20 is for facilitating assistance by a care-giver during use.
Each of a plurality of base members 24 has a perimeter wall 14. Each one of the base members 24 is couplable to an adjoining one of said plurality of base members 24, such that said collapsible walker 10 may be disassembled for ease of transport and storage. Each one of the base members 24 being a separate vertical section. The plurality of base members 24 provides support for the user.
A seat member 26 is coupled to one of the plurality of base members 24. The seat member 26 provides a resting surface of the user during rest. The seat member 26 is designed for supporting a posterior of the user.
The base assembly 12 has a substantially c-shaped cross-section. The base assembly 12 substantially encircles three sides of the user. The base assembly 12 provides vertical support for the user during use. A door portion 28 is operationally coupled to the base assembly 12. The door portion 28 is substantially arcuate such that the base assembly 12 and the door portion 28 has a substantially circular cross-section when the door portion 28 is in a first position. The door portion 28 facilitates ingress and egress from the assembly by the user. The base assembly 12 further includes a closure means 30 for selectively securing the door portion 28 in a first portion whereby the user is substantially encircles on all sides.
The closure means 30 is a magnetic latch assembly 32. The magnetic latch assembly 32 has a first portion 34 coupled to an edge of the base assembly 12. The magnetic latch assembly 32 has a second portion 36 coupled to an edge of the door portion 28. The first portion 34 abutts the second portion 36 when the door portion 28 is in a first position. The first portion 34 is magnetically attracted to the second portion 36.
The hand hold portion 20 further includes a rolled rail member 38 that extends outwardly from a top edge 40 of the base assembly 12. The rolled rail member 38 provides a surface designed to be grasped by a human hand. The rolled rail member 38 provides a hand hold for a care-giver such that the walker assembly 10 may be steadied during use by the care-giver.
A tray portion 42 is couplable to a top edge 40 of the base assembly 12. The tray portion 42 provides a horizontal support surface for user accessories during use. The tray portion 42 further includes a raised rim portion 44 adjacent to a perimeter edge 46 of the tray portion 42. The raised rim portion 44 is for inhibiting spillage from the tray portion 42 onto a horizontal support surface such as a floor. The tray portion 42 further includes a cup holder 48 for selectively receiving a beverage container thereby allowing the user to maintain both hands on the base assembly during use.
The base assembly 12 has an overall height in the range between 36 and 48 inches inclusive. The base assembly 12 has an overall width of approximately 30 inches.
In a further embodiment, a brake assembly 60 is operationally coupled to at least one of the wheels 16. A radio receiver 62 is operationally coupled to the brake assembly 60. A radio transmitter 64 may be carried by the care giver for remotely activating the brake assembly 60.
In use, a user would enter through the door portion, when open the user could walk into the unit close the door portion and be seated in the seat member. A tray portion would be secured to the front of the present invention. The tray portion could secure dining accessories, writing tablets, as other accessories.
