Definitions
- the present invention relates to invalid walkers designed to aid in walking and/or particularly in traversing stairs and the like, having adjustable telescopic legs.
- a huge variety of therapeutic devices, more specifically walking aids is known and commercially available for permanently or temporarily handicapped persons, weakened and/or elderly people.
- users of walking aids are in such a state of health that they would be unable to walk alone, i.e., without the help of a nurse or an additional person they might have been severely limited even in their everyday functions.
- U.S. Pat. No. 3176700 describes a walking aid device having spring-loaded and separately adjustable rear legs
- U.S. Pat. No. 3387617 discloses an invalid walker with telescopic front legs and fixed positioned rear legs
- U.S. Pat. No. 3421529 describes a dual purpose invalid walker having four separately extendable or rectractable legs arranged on a fixed-height frame. The support portions of the legs are directed into opposite directions and during traversing stairs the device leans against three subsequent steps at a time.
- U.S. Pat. No. 4094331 further discloses a reversible dual purpose walk- ing frame to avoid any adjustment of lengths of its legs by traversing stairs; in order to make use of this walking frame for ascending or descending stairs, it should be simply turned upside-down relative to the mode of usage on a horizontal surface. However, in most cases this action requires too much effort from a weakened and/or elderly person.
- U.S. Pat. No. 4922940 describes a further invalid walker with non-adjustable legs for traversing stairs and the like.
- U.S. Pat. No. 4411283 discloses a walking aid with a front leg assembly comprising a pair of guide tubes and a pair of legs capable of moving upwards and/or downwards within the guide tubes, where the legs are fixed at preset locations using locking clips situated on both sides of the assembly.
- U.S. Pat. No. 4777973 describes an alternate walker having extendible/contractible front and rear legs.
- An object of the present invention is to provide a dual purpose invalid walker for handicapped persons, weakened and/or elderly people that can be made use of an aid for either walking on a horizontal surface or ascending/descending stairs or the like.
- a further object of the invention is to provide a device enabling the user to move about freely and safely, to go for a longer walk without any assistance, and hence to help recovery from an operation or simply to keep or improve the
- Another object of the present invention is to provide such a dual purpose invalid walker that can be adjusted and readjusted during usage on stairs or a flat horizontal surface easily and only through a simple action carried out preferably by only one hand.
- a dual purpose invalid walker is thus provided according to the present invention comprising of pairs of legs arranged in first and second planes being in transverse positions relative to the direction of movement, as well as a support frame and/or a bracing frame joining the legs together, wherein the pair of legs being in one of the planes is simultaneously adjustable and fixable, while the pair of legs being in the other plane is independently adjustable and fixable.
- each leg has a telescopic portion and a fixed portion.
- the simultaneously adjustable legs have a rigid or an articulated connection and the element/elements connecting these legs together is/are coupled to a height adjusting column adjoined to the support frame and/or bracing frame.
- a height adjusting column adjoined to the support frame and/or bracing frame.
- FIG. 1 is a back elevation view of an embodiment of the present invention illustrated during the horizontal surface mode of functioning
- FIG. 2 is a side elevation view of an embodiment of the present invention illustrated during the horizontal surface mode of functioning
- Figs. 1 and 2 show a dual purpose invalid walker 1 facilitating preferably ascending or descending movement of handi- capped persons on stairways
- the invalid walker 1 shown in Figs 1 and 2 is comprised of a pair of simultaneously adjustable legs 2 arranged in a first plane being in a transverse position relative to the direction of movement a pair of independently adjustable legs 3 arranged in a second plane being also in a trans- verse position relative to the direction of movement, a bracing frame 4 and a support frame 5
- Each leg has a telescopic portion that can slide into a fixed portion 7
- Fixed portions 7 of legs arranged in the first plane are attached, preferably screwed, through plastic elements 6 to the hollow tubular cold- worked bracing frame 4
- fixed portions 7 of legs arranged in the first plane can be attached to the bracing frame 4 with metal rings 10 too, in order to reach higher loading capability during usage
- the support frame 5 and the fixed portions 7 of legs arranged in the second plane are preferably fabricated via cold-working as an integral unit that is attached, preferably screwed through plastic elements 6 together with fixed portions 7 of legs arranged in the first plane
- rubber handgrips 8 arranged on support frame 5
- the lower ends of telescopic portions of legs are covered with antislip rubber caps 9
- the shown embodiment of the present invention also has a vertically arranged height adjusting column 11 that is attached, preferably screwed through plastic elements 6 to the bracing frame 4 and support frame 5
- the distance between the uppermost apertures of two different arrays of apertures 14 under one another is just the height of a single grade of stairway
- the height adjusting column 11 is equipped with an axially movable snap-bolt 12 containing a pivot engaging with one of the apertures to fix the snap-bolt 12 in a predetermined position
- the above mentioned snap-bolt 12 and the simultaneously adjustable legs 2 arranged in the first plane have an articulated connection therebetween, preferably consisting of solid bracing rods 13
- the telescopic portions of legs arranged in the second plane have an array of apertures 15 consisting of five individual apertures Furthermore, the fixed portions 7 of legs arranged in the second plane are equipped with blocking elements 16 containing also pivots to fix the telescopic portions in predetermined positions
- the bracing frame 4 the support frame 5, the fixed portions 7 of legs and the independently adjustable legs 3 are made of suitable light and rigid material such as pipe of aluminium alloy
- the simultaneously adjustable legs 2, the height adjusting column 11 and the bracing rods 13 are pipes made of brass
- the pivots of snap-bolt 12 and blocking elements 16 are of steel
- snap-bolt 12 has a plastic handle 17 attached to it
- the required height of the invalid walker 1 is set by snapping the pivots of blocking elements 16 mounted on lower ends of fixed portions 7 of legs arranged in the second plane into the corresponding apertures in the array of apertures 15
- the pivot of snap-bolt 12 mounted on height adjusting column 11 is fitted into one of the apertures in the middle array of ap- ertures 14 due to which the ends of legs contacting the surface will be situated all in the same plane.
- This mode of functioning of the dual purpose invalid walker 1 facilitates moving on a horizontal surface without any additional human assistance
- Fig. 3 it is shown schematically how the preferred embodiment of the present invention is used during ascending stairs.
- first handle 17 is drawn back towards the user. After this movement the pivot of snap-bolt 12 no longer fits into any of the apertures formed in the height adjust- ing column 1 and as a result the fixedness of simultaneously adjustable legs 2 also ceases to exist.
- snap-bolt 12 is made to slide axiaily upwards along the height adjusting column 11 and finally the pivot is snapped by the handle 17 into a preselected aperture belonging to the upper array of apertures 14 formed in height adjusting column 11.
- the lower ends of simultaneously adjustable legs 2 will be just with the height of a single grade of stairway higher than lower ends of independently adjustable legs 3.
- the user For traversing upwards first the user puts the simultaneously adjustable legs 2 arranged in the first plane of the above-set invalid walker 1 on the first grade of the stairway and then steps up onto that. At this moment the inde- pendently adjustable legs 3 arranged in the second plane bear on the horizontal surface. Now, invalid walker 1 is lifted up and its legs arranged in the first plane are put on to the next (second) grade and as a following step the user of the invalid walker 1 steps up also onto this grade. With a repetition of the above described process the user can easily and safely climb up the stairs. At the top of the stairway the invalid walker 1 can be set back to the mode of functioning applied on horizontal surfaces (see eg. Fig. 1 ).
- Fig. 4 it is shown schematically how the preferred embodiment of the present invention is used for descending stairs.
- the setting of simultaneously adjustable legs 2 of invalid walker 1 is carried out following the previously mentioned steps, i.e., first handle 17 is drawn back towards the user, which results that the pivot of snap-bolt 12 no longer fits into any of the apertures formed in the height adjusting column 11 and hence the fixedness of simultaneously adjustable legs 2 also ceases to exist.
- snap- bolt 12 is made to slide axially downwards along the height adjusting column 11 and finally the pivot is snapped into a preselected aperture belonging to the lower array of apertures 14 formed in height adjusting column 11.
