WALKER WITH ADJUSTABLE CRUTCII HEAD SUPPORTS The walker of the instant invention has been primarily designed to provide a support structure for the physically handicapped or convalescent patients and which may be utilized as an assist to enable the handicapped or convalescent patients unable to walk unattended to have independent freedom of movement and a means for accomplishing walking exercises with assurance against falling.

The walker includes three different structural assemblages thereof for the support, either partial or substantially total, of the person using the walker. Opposite side hand-grips are provided for use by persons needing only little assistance to walk, under the arm engaging crutch heads are provided to provide further assistance in walking if such further assistance is required and a suspended combined safety belt and crotch sling assembly is'provided for substantially total support if the same is required. In addition, the underarm engaging crutch heads define a back-up safety factor for the handgrip portions of the walker should the person using the walker not be able to support himself by his hands and the combined safety belt and crotch engaging sling assembly defines an ultimate back-up for the handgrips and underarm engaging crutch heads.

By these three different forms of supporting structures being included in the same walker the versatility of the walker is greatly extended and a convalescent patient initially requiring almost total support may progress toward walking without any support through repeated use of the same walker and without fear of falling.

The main object of this invention is to provide a walker which may be utilized not only by persons requiring minimal support to walk but also persons requiring greater amounts of support including almost total support.

Yet another object of this invention is to provide a walker which may be readily adjusted in order to conforni to the height of a particular person using the walker.

Still another object of this invention is to provide a walker including underarm engaging crutch head supports that may be not only vertically adjusted but also laterally adjusted toward and away from each other.

A final object of this invention to be specifically enumerated herein is to provide a walker inaccordance' with the preceding objects which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble-free in operation.

I These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIG. 1 is a perspective view of the walker;

FIG. 2 is a side elevational view of the walker with a convalescent patient therein and utilizing the various patient supporting structures of the walker;

FIG. 3 is an enlarged fragmentary vertical sectional view taken substantially upon the plane indicated by the section line 3-3 of FIG. 1;

FIG. 4 is an enlarged fragmentary vertical sectional view taken substantially upon a plane passing through the mid-portion of one of the underarm crutch head terconnected at their upper ends by means of a pair of opposite side upper connecting members 22 and 24 extending between the uprights l4 and 18 and the uprights 16 and 20, respectively, as well as a pair of opposite end connecting members 26 and 28 extending between the uprights 18 and 20 and the uprights 14 and 16, respectively. If it is desired, the connecting members 22, 24 and 26 may be of a single tubular member bent into U-shaped configuration and secured at its opposite ends, together with the opposite ends of the connecting member 28, to the upper ends of the uprights l4 and 16.

A pair of opposite side intermediate height connecting members 30 and 32 are connected between the uprights 12 and 18 and the uprights 16 and 20, respectively, and an intermediate height end connecting member 34 is connected between the uprights l4 and 16 at the level of the connecting members 30 and 32. Finally, a pair of lower opposite side connecting members 36 and 38 are connected between the lower end portions of the uprights l2 and 18 and the uprights 16 and 20, respectively, while a lower end connecting member 40 is connected between the lower end portions of the uprights l4 and 16 at the level of the connecting members 36 and 38.

The lower end extremities of the uprights 14, 16, 18 and 20 include caster wheel assemblies referred to in general by the reference numerals 42 and accordingly, the frame 12 is mobile in any direction across the surface 43 upon which the caster wheel assemblies 42 are supported.

A combined safety belt and crotch sling assembly referred to in general by the reference numeral 44 is pro vided and includes a waist-encircling belt illustrated most clearly in FIG. 5 of the drawings and designated by the reference numeral 46. One end of the belt 46 is provided with a buckle assembly 48 with which the other free end 50 of'the belt 46 may be operatively engaged in order to adjust the effective circumference of the belt 46. The belt 46 includes peripherally spaced upper anchor rings 52 as well as lower peripherally spaced anchor rings 54.

The assembly 44 further includes a crotch engaging sling panel 56 and the panel 56 is elongated and transversely narrowed intermediate its opposite ends. The panel 56 includes four corner portions from which spring closed hooks 58 are supported and the four corner spring closed hooks 58 are engageable with the lower anchor rings 54 for support of the sling panel 56 from the safety belt 46. Further, the upper opposite side connecting members 22 and 24 include longitudinally spaced front and rear U-bolt anchors 60 to which the spring closed hooks 62 carried by the upper ends of four adjustable length flexible suspension straps 64 are secured. The lower ends of the suspension straps 64 are also provided with spring closed hooks 66 engaged with the upper anchor rings 52.

The walker further includes a pair of opposite side vertical support bars 68 at its rear end and provided with upper and lower guide sleeves 70 and 72 slidable on the connecting members 28 and 34, respectively, whereby the bars 68 are supported from the connecting members 28 and 34 for adjustable shifting toward and away from each other. Also, inasmuch as the guide sleeves 70 and 72 are slidably mounted on the connecting members 28 and 34, angular displacement of the bars 68 about their longitudinal axes is prevented.

Corresponding rear end portions 74 of a pair of frontto-rear extending support arms 76 include vertical sleeve portions 78 slidably disposed on the bars 68. The sleeves 78 include set-screws 80 whereby the height of the sleeves 78 on the bars 68 may be adjusted and the forward ends of the arms 76 include longitudinally spaced apertures 82 by which underarm engaging crutch heads 84 may be secured in adjusted position along the arms 76 and for support therefrom. Suitable fasteners 86 are secured through the crutch heads 84 and the corresponding apertures 82 in the associated arms 76. in this manner, the positioning of the crutch heads 84 along the arms 76 may be adjusted as desired. Further, inasmuch as the sleeves 78 carried by the arms 76 are vertically adjustable on the bars 68, the height of the crutch heads 84 may be varied as desired. Still further, inasmuch as the sleeves 70 and 72 carried by the upper and lower ends of the bars 68 are slidable along the connecting members 28 and 34, the spacing between the crutch heads 84 and their positioning transversely of the frame 12 may be adjusted as desired according to the needs of the individual physically handicapped person or convalescent patient utilizing the walker 10.

In operation, the handicapped person or convalescent patient is assisted into the frame 12 from the front side thereof after the combined safety belt and sling panel 56 have been applied. Then, the lower ends of the suspension straps 64 may be engaged with the anchor rings 52 and the height of the crutch heads 84 as well as their positioning longitudinally and transversely of the frame 12 may be adjusted.

After the convalescent or physically handicapped person has thus been positioned within the walker 10, he may proceed to walk with at least partial support from the walker 10. If but only little support is required, the hands of the person using the walker 10 may be engaged with the connecting members 30 and 32 utilizing the latter as handrails. If additional support for the person using the walker is desired, the height of the crutch heads 84 may be slightly increased so that the person using the walker 10 is also at least partially supported from the crutch heads 84. Finally, if almost total support of the person utilizing the walker 10 is desired, the length of the suspension or support straps 64 may be shortened so that a major portion of the weight of the person utilizing the walker 10 is supported from the combined safety belt and crotch sling assembly 44. Of course, if the person is utilizing the walker 10 only as a mobile hand-rail and he should lose his handgrip as well as his support from the crutch heads 84, the assembly 44 constitutes a back-up support preventing the physically handicapped person or convalescent patient utilizing the walker from falling to the surface 43.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
