with reference now to the drawings , a new stationary patient lift embodying the principles and concepts of the present invention will be described . turning initially to fig1 - 4 , there is shown a first exemplary embodiment of the stationary patient lift of the present invention generally designated by reference numeral 20 . in its preferred form , stationary patient lift 20 is installed in an individual &# 39 ; s home so that they can move disabled and elderly individuals from a bed to a chair or wheelchair and then later back into bed . the lift 20 comprises generally a sling 22 which is lifted by means of a winch 80 which is supported by the roof rafters 88 of the house . the details of the preferred embodiment of the sling 22 are best seen in fig1 and 4 . the sling 22 itself can be made out of any suitable material such as , but not limited to , leather , canvas and the like . at both ends of the sling 22 , a part 24 of the sling 22 is wrapped around a bar 30 . the end of the sling material overlaps to form a reinforced loop part 26 of the sling 22 to hold each side of the sling to a bar 30 . reinforcing sewn rivets 28 are used to keep the overlapping loop section 26 of material secure . each of the two bars 30 hangs from a set of sling corner support straps 42 by means of ring screws 32 secured by nuts 34 . clip hooks 44 are secured to the bottom of each of the sling 22 corner support straps 42 by means of small support rods 46 held in an overlapping sewn loop reinforcement section 48 . the clip hooks 44 are hooked to ring screws 32 to support the sling 22 . the four sling corner support straps 42 are attached by means of lower triangle rings 54 to two main support straps 40 ( the two straps 42 at each end of the sling 22 are supported by one strap 40 at each end ). reinforced overlap loop areas 50 at the top of the straps 42 and reinforced overlap areas 52 at the bottom of straps 40 are fixed to lower triangle rings 54 . each strap 40 has at its top a reinforcement loop 53 which is hooked to upper triangle rings 56 . the upper triangle rings 56 have end threaded support pins 58 extending away . nuts 59 are used for holding the threaded support pins 58 to a single support bar 60 . a ring screw 62 passes through a hole in the support bar 60 and is fixed in place by a nut 64 . a ring 66 passes through the ring screw 62 and also through the a hole in the reinforced loop section 72 of a lifting cable 70 . a reinforcement piece 74 fixes the loop section 72 together . an electrically powered hoist or winch mechanism 80 hangs from the roof rafters 88 by means of a hook 82 integrally fixed above the winch 80 . a winch support rod 90 hangs from the rafters 88 through the ceiling 84 to a hook 92 at the bottom of winch support rod 90 . the hook 92 of the support rod 90 is hooked to the hook 82 of the winch 80 . a cover plate 86 can be placed around the support rod 90 underneath the ceiling 84 to provide an attractive appearance and to give the support rod 90 some added stability . the support rod 90 is mounted to the rafter 88 by means of a bracket 94 . the support rod 90 is threaded at its top and a nut 96 holds the rod 90 to the bracket 94 . the bracket 94 is bolted to the rafter by means of a bolt 98 . as can be seen more clearly in fig3 the lifting device is powered by electricity from a standard electrical socket 106 , the ac current running through ac power cord 104 to power box 100 . power box 100 is housed in power box housing 120 . ac current from the power cord 104 is sent to ac / dc transformer 126 which transforms the electricity from ac to dc . the dc goes through a circuit protector 128 which protects the circuitry of the device and which contains the switching mechanism for switching the equipment on and off based on signals from a hand control switch box 110 . the hand control switch box 110 hangs down from the housing 120 by means of a control switch cord 108 to a level an individual can reach . a reel 130 enables the level of the switch box 110 to move up or down as desired by the user . when the device is switched on , direct current is sent through dc power cord 102 to the wench motor allowing the wench to be able to lift or lower a patient . support plug 124 for cord 102 and support plug 124 for cord 104 can be positioned on the housing 120 to support the respective electrical cords . the power box 100 is mounted on ceiling support beams 134 by means of screws 132 . use of the patient lifting device of the present invention is very easy . when it is necessary to move a patient from a bed to a chair or wheelchair , the sling 22 is slid under the patient and the power is turned on . the up switch is activated and the device lifts the patient out of bed . a chair or wheelchair is then placed under the patient and the lowering switch is activated . the patient is then lowered into the chair or wheelchair . the device is then turned off . when it is desired to return the patient to bed , the sling 22 is again slid under the patient and the device is turned on . the lift switch is activated and the patient will be lifted out of the chair or wheelchair . the bed is then rolled under the sling 22 and the lowering switch is activated , lowering the patient into the bed . the device can then be turned off . an alternative embodiment power box 200 having emergency battery backup power for power outages is shown in fig5 and 6 . the alternative power box 200 is housed in a housing 220 having an access door 222 . a battery 224 can be electrically connected to a switching device 226 which activates the battery power when needed during an electrical power outage . use of the alternative power box is the same as in the initial preferred embodiment . the only difference is that during a power outage , the switching device 226 will automatically activate battery power . another alternative embodiment power box 300 having a hand held wireless remote controller 310 is shown in fig7 and 8 . the hand held remote controller has an on / off switch 312 and an up / down switch 314 . the housing 320 of the power box 300 has an access door 322 and a receiver eye 324 for receiving the remote controller &# 39 ; s signal . use of this alternative power box is the same as the initial preferred embodiment except that the hanging controller box 110 is replaced with a wireless controller 310 . it is apparent from the above that the present invention accomplishes all of the objectives set forth by providing a new lift for patients comprising : a patient holding means ; a means for supporting the patient holding means from above , the means for supporting permanently fixable to a stationary and permanent structure ; a means for raising and lowering the patient ; and a means for activating the raising and lowering of the patient ; whereby the lift can be permanently mounted in a building and a patient can be lifted into and out of bed using the lift . the patient holding means can be a supported sling . the means for raising and lowering the patient can be a wench . the means for activating can be a hand held controller , which can be wireless . the lift can be powered by alternating current provided from a standard electrical outlet socket . the lift can have alternate dc battery power for use during alternating current power outages . with respect to the above description , it should be realized that the optimum dimensional relationships for the parts of the invention , to include variations in size , materials , shape , form , function and manner of operation , assembly and use , are deemed readily apparent and obvious to those skilled in the art , and therefore , all relationships equivalent to those illustrated in the drawings and described in the specification are intended to be encompassed only by the scope of appended claims . while the present invention has been shown in the drawings and fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiments of the invention , it will be apparent to those of ordinary skill in the art that many modifications thereof may be made without departing from the principles and concepts set forth herein . hence , the proper scope of the present invention should be determined only by the broadest interpretation of the appended claims so as encompass all such modifications and equivalents .
