/ //I III III PATIENT LIFT AND EXERCISE APPARATUS BACKGROUND OF THE INVENTION 1. Field of the Invention Broadly, the present invention relates to devices for lifting and transporting objects. In a, specific application, the present invention relates to a device that can be employed in nursing homes and hospitals to lift, transport and provide exercise for invalids or bedridden patients with a minimum amount of effort on the part of a nurse or attendant.

2. Description of the Prior Art In hospitals and nursing homes, it is often necessary to move or transport invalids or other bedridden patients from one area of the hospital or home to another area, such as when a patient is to receive physical therapy. Common vehicles used for this purpose are wheelchairs and wheel mounted stretchers. One problem encountered with conventional wheelchairs or stretchers is that it is difficult for the nurse or attendant to safely transfer the patient from the bed to the wheelchair or stretcher.

A variety of patient lifters have been employed to lift and transport patients. Such lifters vary from stationary mounted lifters used on car tops and bath tubs, to lifters which are capable of being wheeled from one location to another. While conventional lifters are capable of being moved about. they generally provide no means for slightly repositioning or moving the patient without moving the entire lifter which may provide difficulties in confined areas. Moreover, movement of the entire assembly for effecting only small movements of the patient may cause unnecessary jostling.

Another problem associated with known prior art lift construction is that the devices are relatively fragile and, because of their narrow bases, are subject to tipping. Larger lifts, while being stronger and more stable, are undesirable to the extent that they are difficult to move and maneuver in tight places. Because of the design and relative positioning of the various elements employed in many conventional lifts, relatively large, heavy construction members employing relatively complex mechanisms are required for their safe operation.

SUMMARY OF THE INVENTION The present invention provides a combination patient lift and exercise apparatus which can be used in hospitals and nursing homes as well as other places to lift, position and transport invalids or bed-ridden patients as well as to exercise the lower limbs of such individuals. The apparatus of the prevent invention comprises an adjustable-width base assembly mounted on casters. A vertical mast assembly housing a height adjusting mechanism is supported by the base assembly and an exercise mechanism, comprising a drive motor connected to foot pedals through a chain and sprocket arrangement. is attached to the lower portion of the mast assembly. A boom assembly having a lateral patient positioning mechanism and an upper limb support bar extends horizontally from the mast. In operation, a sling carried by the boom may be adjusted along the boom and the boom may be raised or lowered to properly position the patient for use of the exercise mechanism.

Manual adjusting means are provided for changing the width of the base so that the assembly may be moved from place to place through confined or narrow passages. The base may be expanded when the assembly is to be used for exercising purposes or to provide increased stability during movement through relatively unconfined spaces. Manual adjustment of the sling position is also permitted whereby the patient may be moved small amounts without moving the lift structure on its casters. By this means, relatively small movements as may be required for X-rays and other procedures may be made with a minimum of discomfort to the patient.

The free end of the boorri is raised or lowered by operation of a drive mechanism carried in the vertical mast assembly. Using this design, a heavy duty, although relatively light, mechanism can be employed to effect boom movement without increasing the external dimensions of the device and unduly limiting its utility.

The stability and strength of the apparatus of the present invention permit it to be combined with the exercise means so that the lift device may serve a dual function. By use of the present apparatus, it is also unnecessary to go through the multiple step process conventionally employed when a patient is to be removed from a bed by a lift apparatus and then removed from the lift apparatus to be positioned in an exercise apparatus.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENT Referring to the drawings, and more specifically to FIGS. 1 and 2. the patient lift and exercise apparatus of the present invention is indicated generally at 10. The apparatus 10 comprises an adjustable-width, base assembly indicated generally at 11, a vertical standard or mast assembly indicated generally at 12, a height adjusting mechanism indicated generally at 13, a lift arm or boom assembly indicated generally at I4, a lateral patient positioning and support mechanism indicated generally at 15, and a height adjusting brace 16 connected between the mast assembly 12 and the boom assembly l4. Attached to the lower portion of the mast assembly 12 is an exercising mechanism indicated generally at I7 employed to exercise the lower limbs of a patient. The mechanism 17 includes an electric drive motor 18, a crank assembly, indicated generally at I9, having crank arms 20a and 20b and pedals 2] con- 3 nected respectively to arms 2021 and /2. The outp ut shaft of the motor 18 is connected in a conventional manner to the crank assembly 19 through a suitable. conventional drive mechanism enclosed in a housing 22. The drive mechanism may bea typical chain and sprocket arrangement like that employed on a bicycle. The pedals 21 are provided with straps 23'to hold the patients feet in contact with'the pedals.

The base assembly 11 includes parallel rail members 24 connected by a cross member 25 which forms a housing for extendable members 26a and 26b, illustrated in FIGS. 9 and 10. Extension of the members 26a and 26b is effected by rotation of a hand crank 28. To allow the apparatus 10 to be moreeasily manuvered about. casters 27 are employed, being suitably fastened to the rails 24. Details in the construction and operation of the base assembly 11 will be described hereinaf- I81.

Referring further to FIGS. 1 and 2, the mast assembly 12 includes a'housing 29 attached to the cross member 25 anda vertically movable traveling nut 30. The nut 30 has an integrally formed mounting bracket or flange 32 having an eye 33 for pivotally securing the brace 16. A removab le end cap 34 attached to the upper end of the housing 29 provides a pivotal mounting means for the boom assembly 14. Further details in the construction and operation of the mast assembly 12 and height adjusting mechanism 13 will be described more fully hereinafter.

The boom assembly 14 is shown comprising a housing arm 35 having a fixed mounting bracket '36 with an eye 37 provided for pivotal connection of the upper end of brace 16, an adjustable upper limb support bar 38 secured to the arm 35 by a bracket 39, and the patient positioning and support mechanism 15 which includes a non-rotatable traveling nut 40 having an integrally formed flange 41 with an eye 42 to attach a suitable sling, indicated at S. that may be employed to lift a patient. The support bar 38 is provided with a plurality of holes 3811 for achieving the desired position of a patients upper limbs when the exercising mechanism 17 is being used.

With reference now to FIGS. 3 and 4, the mechanism 15 includes the traveling nut 40 previously described having internal threads 44 which engage external threads 45 formed on an elongate shaft 46. The shaft 46 is rigidly secured to a crank handle 43 and rotation of the crank handle and attachedshaft 46 causes the traveling nut 40 to move within the housing 35. It will be appreciated that the housing arm 35 surrounds the nut 40 in a mannerto prevent rotation of the nut while permitting longitudinal nut movement. To this end, a

longitudinal slot 51 formed along the bottom of the housing 35Jreceives the flange 41 and permits the flange; to advance while preventing nut rotation. The shaft 46 is supported in the housing 35 by a support bushing 47;whieh issecured to the housing 35 by suitable fasteners 48. Rotatable movement of the shaft 46 in the bushing 47 is assisted by thrust plates 49 and 50 of brass or other suitable material. Details in the construction of the mast assembly 12 and height adjusting mechanism 13 are best illustrated with reference to FIGS. 5 and 6. A vertical shaft 52 having external threads 53 which engage internal threads 54 on the traveling nut 30 is disposedin the housing 29. A slot 29a provided in the housing '29 allows vertical movement of the traveling nut 30 and replacement of the entire mechanism 13. Force exerted against the shaft 52 through the traveling nut 30 by the weight of the user in the sling S is partially relieved by a roller 32a mounted on the flange 32 and in rolling contact with the housing 29. The roller 32a prevents the nut 30 from binding in the housing 29. At the lower end of the shaft 52, a shoulder 55 supports the shaft on a lower guide and support member 56 which includes a thrust bearing 57. The guide member 56 is secured to the housing 29 by threaded fasteners 58 or other suitable means. The upper end of the shaft 52 is supported in the mast by an upper support and gear assembly housing 59 provided with a second thrust bearing 60 acting against a spacer 61. Threaded fasteners 62 are employed to secure the gear assembly housing 59 to the housing 29. Disposed in the housing 59 is a rotary drive gear 63 rigidly secured to the upper end of shaft 52 by a key 64. A worm gear 65 mounted on a shaft 66 is attached to the crank handle 31. The end cap 34, secured to the housing 59 by threaded fasteners 67, is provided with a groove 68 and a pivot pin 69 to allow pivotal movement of the arm portion 35 in the boom assembly 14.

As can best be seen by referring to FIG. 7, the gear assembly housing 59 provides rotary support for the shaft 66, within bearings 71a and 71b, spacers 72a and 72b and end plates 73a and 73b. Each end plate 73a and 73b is fastened to the housing 59 by suitable fasteners 74. A retainer clip 76 prevents lateral movement of the shaft 66 in the housing 59. The worm gear 65 is prevented from rotating on the shaft 66 by a key carried in a key slot formed in the shaft. The crank handle 31 engages flat surfaces 77 on the shaft 66 to prevent rotation between the handle and the shaft. The surfaces 77 allow the crank handle 31 to be removed when not in use.

Referring to FIG. 8, the nut 30 is disposed in the housing 29 which has a slot 29a through which the flange 32 protrudes. The brace 16 is pivotally secured to the flange 32 by a pin 78 equipped with retainer clips 79a and 7912.

Details in the construction and operation of the adjustable width base assembly 11 may best be described by reference to FIGS. 9 and 10. Extension of the base assembly 11 is effected by rotating a shaft 80 having external left hand threads 80a on one end portion and external right hand threads80b on the opposite end portion. The threads 80a engage integrally formed internal threads 81a on member 26a and threads 8012 engage internal threads 8112 on member 2612. The shaft 80 is held in position by an integrally formed stop 82 in cross member 25. The width of the base assembly 11 is varied by turning the crank handle 28 attached to the shaft 80.

In operation, when it is desired to lift, reposition or transport a patient. the apparatus is moved up to the bed. The attendant makes the proper width adjustments of the base assembly 11 by rotating the handle 28 so that the base will fit between the legs of the bed. Having correctly positioned the apparatus 10, the attendant positions the sling suspended by the arm 35 by turning the crank handle 31 in the appropriate direction for raising or lowering the sling as required. Any conventional sling or stretcher. indicated at S. having suitable support straps or chains which may connect to the eye 42 in the patient positioning and support mechanism 15 may be employed.

If it is desired to move or reposition the patient on the bed. it is not necessary to move the apparatus 10. Lateral movement of the patient can be effected by rotating the crank handle 43 on the mechanism 15. In this situation, the attendant first lifts the patient from the bed by rotating the crank handle 31 on the height adjusting mechanism 13. After the patient has been raised. lateral movement is effected by rotating the crank 43 which causes the sling to travel along the boom as previously explained.

The same general procedure is followed by the attendant when transporting a patient from one area to another area. The apparatus is rolled up to the bed, the patient placed in the sling and lifted from the bed. The casters 27 then allow the apparatus 10 and supported patient to be moved easily from one area to another.

When it is desired that the apparatus 10 be used for exercising, the patient is placed in any suitable exercise sling, indicated at S, supported from the eye 42. The patient is then positioned. by turning the crank handle 43 on the patient positioning mechanism l5, so that his feet are in contact with the pedals 21 of the exercising mechanism 17. The patient's feet are held in contact with the pedals 21 by the straps 23. The upper limbs of the patient are supported by any suitable second sling (not illustrated) suspended from the support bar 38. The position of the second sling may be adjusted laterally relative to the boom by properly positioning the sling supports in the holes 380 of bar 38. It may be necessary to increase the width of the base assembly 11 to provide greater stability to the apparatus 10 when being used as an exerciser. The motor 18 is a variable speed motor to provide the necessary exercise for a patient's lower limbs.

The foregoing disclosure and description of the invention is illustrative and explanatory thereof. and various changes in the size. shape and materials as well as in the details of the illustrated construction may be made within the scope of the appended claims without departing from the spirit of the invention.
