Abstract
The rail assembly comprises a handrail 1; a plurality of cantilever arms 2; and a mounting board 4; wherein the cantilever awns are each pivotally attached to the base plate at a first end and are each secured to the underside of the handrail at an opposing end such that the rail assembly is configurable between a folded out position and a retracted position. The rail assembly may include a locking pin 6. A screw adjuster 5 may be located on each cantilever arm to align consecutive rail assemblies with one another. Channels 3 may provide the pivotal attachment between the cantilever arms and the base plate. The cantilever arms may be telescopically extendable. The rail assembly may be mounted with similar assemblies on opposed stairway walls or balustrades in successive pairs to provide underarm support to elderly or infirm persons, thereby aiding their ascent or descent along the stairway.
Description
Hand & Armpit Support Stair Climbing Aid
FIELD OF THE INVENTION:
The present invention relates to a stair climbing aid for patients with leg injuries. The higher rail gives hand & armpit support for greater safety and interference free passage from the cantilevered design. Fold back features allow for normal traffic when "not in use" and a telescopic strut option permits adjustment of height & width between support rails to cater for changes in stance of a rehabilitating patient.
Definitions in this Citation: "Balustrade" -A generic name proposed by applicant to allude to a stair banister rail.
"Balusters" -Upright posts & boards supporting staircase handrail.
PROBLEM, NEAREST PATENTS & PRESENT STATE OF THE ART: According to the Royal Society for the Prevention of Accidents statistics, 60% of older persons' deaths in homes result from accidents on staircases. The problem with nearest patented stair climbing aid inventions is that the rail is at a low height, intended for hand grip use only, which gives insufficient support and confidence to impaired mobility users. Furthermore, they use tie rods causing interference with the smooth passage of the user when climbing up the stairs. Tie rods also increase the cost of stair climbing aids.
SOLUTION & OBJECT OF PRESENT iNVENTION.
The object of the present invention is to overcome above problems by providing a dual, retractable, interference free, hand & armpit height support, inexpensive stair climbing aid, supplied in dual set assemblies of armpit rail & three cantilevered struts pivotally linked to channel supports on a mounting board, for consecutive installation on. walls and balusters of stairs. The high support rail doubles as hand and armpit support -fig. 1. This increases safety for impaired mobility users. The adjustable telescopic struts option allow for quick adjustment of height & width between rails, useful when changes are needed by rehabilitating leg injury patients getting better and standing more erect.
Patent Searches -No Anticipations: At filing, a Worldwide Patent Database Search on espcenet website showed no prior art for a retractable, hand & armpit support stair climbing aid, interference free due to fastening on underside to cantilevered struts linked to pivot means.
Novelty Step differences with nearest "Prior Art" patents listed below:-US 202/005513A1 -(BERNER) -see figs. 1,2 & 4.
US 4939876 Al -(BERNER) -see figs. 1, 3A & 3B.
DE 19522337 Al -(HOELZER) -see all figs. JP 07011749A -(TSUKASA) -see EPODOC abstract and all figs. All the above differ significantly in inventive step because they embody:-A rail for hand support only -present invention rail provides hand & armpit support.
Tie rods used give interference to user -present invention embodying cantilevered struts provide "interference free" passage climbing up & down stairs.
SUMMARY OF INVENTION:
A hand & armpit support stair climbing aid, comprising a support rail, fastened on underside to cantilevered struts, linked to pivot support channels, attached to a mounting board for fastening to stair walls & balusters; the struts have stops to hold them in the angled out "in use mode", ball catches to hold them in the retracted "non use mode" and a telescopic strut option for adjustment of height & width between support rails to cater for changes in the stance of a rehabilitating patient.
USES & ADVANTAGES: 1. A stair climbing aid for use & rehabilitation of patients with leg injuries.
2. Gives greater confidence & safety as higher rail gives hand & armpit support.
3. Gives interference free passage from cantilevered struts attached to underside of rail.
4. Easy installation on stairways with short consecutive assembly sets.
5. Fold back retractable feature allows for normal traffic when not in use.
6. Telescopic strut option adjusts height & width between rails to suit stance of user.
REFERENCE TO DRAWINGS: Figure 1 illustrates a person using the first of two pairs of stair climbing aid units installed consecutively on wall (not shown) & baluster of staircase; the units show the optional telescopic struts which allow for altering height & width between rails, as needed by leg injuiy patients to. cater for changes in their stance.
Figure 2 is an illustration of a basic retractable, stair climbing aid assembly unit comprising armpit rail fixed length struts, linked to pivot support channels, fixed on the mounting board, shown in the "in use mode".
Figure 3 is the same Stair Climbing Aid assembly unit as in fig 2, shown in the retracted "not in use mode".
Figure 4 is an illustration of the Stair Climbing Aid assembly unit embodying the optional adjustable telescopic struts shown in the "in use mode".
Figure 5 is the same Stair Climbing Aid assembly unit embodying the optional adjustable telescopic struts as in fig 4, shown in the retracted "not in use mode".
Figure 6 details the stair Climbing Aid in the "in use mode", illustrating the optional telescopic strut assembly, installed on a staircase with stair wail not shown for cLarity.
