Description

COMPACT-COLLAPSIBLE WHEELED WALKING AID
TECHNICAL FIELD The invention relates to a walking aid, more in particular a wheeled walking aid, such as a rollator, that is collapsible for storage and transport.
BACKGROUND In prior art there are many types of walking aids. Many walking aids are collapsible for easy storage and transport in a car for example. A walking aid generally comprises a frame with three or four wheels mounted on the frame, support bars with handles, and a seat support. The ergonomics of a walking aid necessitate enough free space in the frame and enough free space between the handles for the user to walk unhindered whilst providing support and stability, In the prior art the walking aid can be made compact by folding and retracting the frame, the support bars, as well as the seat support.
RELATED ART Patent applications WO2012089634 and WO2012089700 are examples of walking aids in the prior art. These documents describe walking aids with a frame, wheels, support bars with handles, and a seat support. The frames can be folded in two directions, to reduce both the dimension in a longitudinal direction, the length, and the dimension in a transverse direction, the width. However the upward dimension, the height, cannot be changed significant. In prior an walking aids for outdoor use have large diameter front wheels and large diameter rear wheels, while for folding a simple mechanical mechanism has been applied. For this reason, foldable walking aids in the prior art remain relatively bulky when made compact for long-term storage or transport and the folding action is relatively onerous. In addition when the walking aid isin a collapsed state and stands in an upright position on a floor, it does not stand very stable, and/or in this collapsed state the walking aid cannot easily be rolled.
OBJECT OF THE INVENTION
The present invention intends to solve a complex of problems still present in the designs of prior art: - it is important, in particular if the user of a walking aid is a disabled person, that the collapsing and extending operations are easy and do not need great physical effort; - it is desirable for temporary storage in home that the walking aid can be adjusted to a semi-compact state to stand on a floor in an upright stable position with the handles high; - it is desirable that the walking aid in a semi-compact state for temporary storage can roll to move it; - it is desirable that, when adjusting the walking aid between an extended state for use as a walking aid and a semi-compact state for temporary storage, the level of the handles does not change significant; - it is desirable for long term storage or transport that the walking aid can be adjusted to a compact state to stand on a floor in an stable upright position with the handles low; - it is desirable for travelling in an airplane that the walking aid can be adjusted to a compact state, compact enough to meet the major airline cabin baggage allowances; - it is desirable for outdoor use that the diameter of the front wheels is not less than 180 mm,
SUMMARY OF THE INVENTION The present invention relates to a walking aid, more in particular a wheeled walking aid, such as a rollator, wherein said walking aid is adjustable between three states, wherein said walking aid comprises a frame, wherein in a first state of said walking aid said frame is in an extended state for use of the walking aid, wherein in a second state of said walking aid said frame is in a semi-compact state, for example for temporary storage, wherein in a third state of said walking aid said frame is in a compact state, for example for long-term storage and/or transpont, wherein said frame comprises two lateral frame parts that are connected to each other by at least one transverse element, wherein each of said lateral frame parts comprises at least a front wheel and a rear wheel, wherein each of said lateral frame parts comprises at least two components, a first component which extends in a substantially upward direction at least in the extended state of said frame and a second component which comprises at least said rear wheel, wherein said second component comprises at least two parts, wherein a first part is connected to the first component with substantially a first end thereof, and wherein a second part, which second part comprises said rear wheel, is connected to the first part at the other, second end of the first part in a hingeable manner, such that the first part and the second part are hingeable with respect to each other.
For example, the walking aid may be a rollator that is easily adjustable between three states, a first extended state for use as a walking aid, a second semi-compact state for temporary storage, and a third compact state for long-term storage and/or transport. The three states may in particular be stable states of the walking aid. The second, semi- compact state may additionally or alternatively be referred to as an intermediate collapsed state. The third, compact state may additionally or alternatively be referred to as a collapsed state.
In the second state the walking aid can stand stable in an upright position on a floor. In the second state the walking aid can roll on a floor in an inclined position. When adjusting the walking aid from the extended first state in a position for use as a walking aid to the second semi-compact state in an upright position the level of the handles does not change significant. In the third compact state of the walking aid the dimensions are small enough to meet the major airlines cabin baggage allowances. In the third compact state the walking aid can stand stable in an upright position on a floor.
Adjusting said frame of the walking aid between the three states, for example between the first state and the second state and/or between the second state and the third state, may take place in any suitable way. For example this may take place by folding and/or sliding and/or hinging.
Sald first and/or second component may for example be a substantially elongated component.
