13 Claims.

This invention relates to a walker for invalids, hospital bed patients, cripples and others temporarily or permanently incapacitated from walking due to weakness or physical inability causes.

One object of the invention is to provide a simple, reliable and efficient type of wheeled device of this character whereby an invalid or patient may be supported and enabled to move himself from place to place.

Another object of the invention is to provide a device of this character which may be arranged alongside a bed and which embodies a base to extend under the bed and adjustable and resilient supporting means adapted in such arrangement of the device to extend over the bed, whereby a patient may raise himself out of bed and move from place to place with the aid of the walker and then, on returning to a position alongside the bed, may lower himself onto the bed again.

Still another object of the invention is to provide novel and improved supporting and raising and lowering means for the purpose, which raising and lowering means may be operated by the patient or an attendant and is simple of construction and so constructed that it will not slip and cause the patient to fall.

Still another object of the invention is to provide adjustable supporting means including resiliently mounted arm pit or shoulder engaging members which will accommodate themselves to the up and down body movements of the wearer and allow easy walking movements reducing strain and fatigue.

Still another object of the invention is to provide a walking device which is free from complex parts liable to get out of order and which may be manufactured and sold cost With these and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts, hereinafter more fully described and claimed, and as' the walker.

at a comparatively low hoist or gear forming part of the raising and lowings, l designates a wheeled carriage including a horizontal base frame which is U-shaped and comprises two longitudinal sidebars 2 connected at their forward ends by a cross bar 3, said base frame being open at the rear to provide a passageway a allowing free movement of the legs of thepatient into and out of the space between the side bars under certain conditions when the patient is entering or leaving the device. The base frame is provided at its front corner and at the rear ends of the bars 2 with supporting wheels 5 preferably of caster wheel type.

Fixed to and rising from the center of the bar 3 is a standard or upright in the form of a rod 6 having its upper end extended rearwardly and curved to form a suspension arm I overhanging the open center of the base frame in rear of the bar 3. At spaced points in its length the arm I carries guide pulleys 8 in guided engagement with which is a suspension chain, rope or cable 9. The rear end of this member 9 depends at the rear end of the arm 7 and carries a body supporting sling. This sling consists of a horizontal transverse rod or bar If] centrally connected to the suspension member 9 and carrying at its ends depending springs II to which are attached loops I2. The transverse bar It! is arrangedto bridge over and across the head or shoulders of the person to be supported so that the arms of the person may be projected through the loops l2 to bring the loops under the arm pits of the person, whereby the body of the person may be supported in an upright position-with his legs depending through the open carriage frame and with his feet resting upon the floor or ground. As the loops are resiliently supported they are adapted to move up and down as well as forwardly and backwardly to accommodate themselves to and permit of the body movements of a person in the normal course of walking, particularly the irregular movements of an invalid, thus allowing the person to walk more freely and with less restraint and fatigue.

Slidably mounted for adjustment on the upright 6 is a gear casing I3 to-whichare secured rearwardly extending handle bars [4 provided with hand grips l5. These grips are adapted to be engaged by the hands of the person so that by the use of his hands the-person may assist in supporting himself in walking position,- and by means of the handle bars the walker; device maybe controlled and guided with-facility.

Attached at-its upper end to the lower or forward end of the flexible supporting member 9 is a threaded rod l 6 which extends down and through the gear casing 13. In the casing are arranged a gear nut l1 engaging the rod and worm gear mechanism 18 for rotating the nut, wherebythe rod may beraised and-lowered to effect up and 'down-travel' 'of the member 9 'sothat the sling ID may be raised and lowered."

The shaft of the worm gearing extends outwardly from the casing and has attached thereto a crank handle or wheel [9 whereby the gearing may be actuated byqthe patient or an, attendant to adjustzthe slingto'fa proper-elevation and to adapt the patient to raise himself from or lower himself onto a bed, or permit these operations.

to be performed by an attendant if the patient is.

unable to perform them.

In the use of the device, as in connection with an invalid or bed patient in a hospitahthe device is brought alongside the bed with a portion of the base frame I projecting under the'bed so that the handle bars and sling will extend over the bed and in position totbe manipulated by the patient. The sling, ifiraised, is then lowered so thatthepatient may thrusthis arms through the loops l2 and. bringthem. under his arm pits and grip thehandle bars to assist in raising himself up,,.in,bed .andinlpositionto bring hisrlegs beyond thesideof thebed. so.that by elevation of the slingithepatient may be lifted and supported in standing.v position ready to" walk;v This lmovementofthe sling to raise the/patientto standing position maybeefiected by means. of the gearing, operated either; bythe patient or, if he is unable, by an attendant. The character of thegearing used allows thisto. be easily done and the sling to be adjusted .to the. exact elevation desired to support; theqpatient with more. or less of his weight on his feet. iTheipatient may then walk While supported by the: walking device, or the patient may employwa walkingmotion if he is not not be accidentallyreleased and-allow the patient to fall....

From the'foregoingidescription, taken in connectionv with the drawing, theconstruction and modepf operationof, the walking device will be readily nnderstoodswithonti a further and extended: description, and, it will be seen that the device,combinexrsimplicity of construction with,

the manifoldadvantages setforth. While the constructiondisclosed is preferred, it is to be understood thatchanges in thevform, construction and arrangement-.ofparts may be made, within thescope of theappended claims, without idepar-ting from. the-spirit or sacrificing any of the advantages of the invention.
