Turning to FIG. 1, therein is shown the present invention 10 including a patient lilting assembly 12 which may be used to lift and move a patient 24 from a bed 48 to a chair 22. Bed 48 may be a conventional bed having an upper surface 49 upon which the patient sleeps along with supporting legs 50 at each corner. The patient lifting assembly 12 is illustrated attached to an upper end of an upright standing pole or stanchion 14 mounted on base 16 wherein a load line 18 passes through the interior of the pole 14 and lifting assembly 12 having a connector 17 on its lifting end for attachment to a sling assemble 20 joined to a patient lifting chair 22 with a patient 24 being carried therein. Patient chair 22 may be a wheelchair as illustrated in FIG. 1. The base 16 is expected to be fixedly mourned on a supporting surface such a floor as shown in FIG. 1 proximate to bed 48 and chair 22. The patient 24 can use the bed 49 to manually swing themselves around over the bed or to push themselves around over the wheelchair 22. A rope or strap (not shown) can be installed on the opposite side of the bed 49 that can be used to swing over the bed. If another person is present they can swing the patient 24 around over the bed 49 or the wheelchair 24. The lower end of the load line 18 passes through the lower end of the pole 14 and over a pulley 26 attached to the lower end of the pole 14 within an enclosure 28 wherein the lower end of the load line is connected to an electrically powered wench 30 connected through electrical wiring 32 to a handheld electrical controller 34.
The patient lifting assembly 12 is manually horizontally rotatable by means of a special bearing assembly 36 mounted in the pole 14. Also shown as a pan of the patient lifting assembly 12 is a vertically adjustable bracket 36 mounted onto upright pole 14 and having a plurality of vertically spaced apart apertures 37 therein for allowing insertion and removal of a pin 38 on a lower end of brace 42 having one end of the brace extending from the upright pole 14 and a second end attached to arm 40 so that the horizontal arm 40 is supported by the brace 42 so as to provide support for the arm 40 which extends laterally from upright pole 14. The pin 38 can be removed from a first aperture 37 and then placed in a second aperture 37 so as to allow the arm 40 to be height adjustable. The patient lifting assembly 12 also includes a plurality of pulleys 26 and 44 which extend into the interior of the patient lifting assembly 12 to reduce friction of line 18 with the pulleys 26, 44 being attached to the gin pole assembly 12 using mourning brackets 46. Elbows 63, 64 are also shown.
Turning to FIGS. 2 and 3, therein is shown the patient lifting assembly 12 with the upper portion of pole 14 and arm 40 extending laterally therefrom and including a brace 42 having a lower end joined at pin 38 to the adjustable bracket 36 and showing the upper end of brace 42 connected to mounting bracket 52 on arm 40 with a pivot point 54 thereon and also showing the arm 40 being attached on one end using a pivotal member 58 which allows the arm 40 to be angularly adjustable manually from a user selectable position horizontally perpendicular to the pole 14 up to an angle of approximately 45 degrees with the pole 14 as shown in FIG. 2. Also shown are the pulleys 44 with mounting brackets 46 for attachment to the patient lifting assembly 12 wherein the pulleys have an outer peripheral portion 56 which extends into the interior of the patient lifting assembly 12 so that the outer periphery of the pulley 44 is approximately at the center line of the patient lifting assembly 12 so that the load line 18 can pass through the inside of the pole 14 and arm 40 so that the load line travels on the inside of the patient lifting assembly 12 spaced away from the interior surface of the pole 14 and arm 40 thereby reducing friction between the load line 18 and the inside surface of the patient lifting assembly 12. Also shown are the pulleys 44 attached to the members of the patient lifting assembly 12 using mounting brackets 46. An alternative angle of about 45 degrees for the arm 40 is shown in phantom line. FIG. 2 shows the patient lifting 38 attached to a pole 14. FIG. 3 shows the patient lifting assembly 12 in a folded configuration which is accomplished by disconnecting one end of the brace 42 from arm 40 wherein arm 40 is folded so as to be substantially parallel to pole 14.
Turning to FIG. 4, therein is shown an enlarged view of the elbow portion 64 of the patient lifting assembly 12 disposed on a distal end of arm 40 along with the pulley 44 and the mounting bracket 46 wherein the pulley 44 is attached thereto using a fastener 62, e.g., a nut and bolt as shown herein or the like. It can be seen that the periphery 56 of the pulley extends into the interior 60 of the hollow elbow portion 64 of patient lifting assembly 12 so that the load line 18 passes with a minimum amount of friction through the inside of the members of the patient lifting assembly 12. The pulley 44 is shown attached to an elbow portion 64 of the patient lifting assembly 12. Elbow 63 is constructed similarly to elbow 64.
The present invention 10 has an arm 40 which extends laterally away and out from the pole 14 allowing the patient 24 to remain spaced apart from the pole 4 to 6 feet while being raised or lowered keeping the patient safely and unencumbered away from pole 14.
Turning to FIG. 5, therein is shown an enlarged view of the rotating member 35 showing portions of the pole 14U above the rotating member 35 and a portion of the pole 14L below the rotating member 35. Rotating member 35 could comprise a slewing bearing having an inner ring 66 and an outer ring 68 which rings have a plurality of ball bearings 70 disposed in between the inner and outer rings which ball bearings roll on a race or bearing track 72 which is formed in the surfaces of the mating inner and outer rings along with an upper and lower seal 74 and 76 which keep the space between the inner and outer rings clean. Also shown is an upper flange plate 78 which is welded to the upper pole 14U section at 80 along with a lower flange plate 82 which is welded at 84 to the lower pole section 14L. The inner ring 66 is joined to the upper flange plate 78 using nuts and bolts 86 and outer ring 68 is joined to lower flange plate 82 using nuts and bolts 88 so that the entire assembly of the rotating member 35 is fixedly attached to the pole 14 The rotating member 35 allows the pole 14 to rotate in a 360 degree arc.
