the comfort seat and commode device 10 of the present invention is shown in fig1 . the device 10 includes a framework 11 ( fig6 a ), which may be constructed in many different shapes including , but not limited to a cylindrical shape , a trapezoidal - shaped block , an irregular shape , etc . a framework in the cylindrical form would permit its construction using a single , circular base member and a single circular top member separated by vertical members . however , in one embodiment , which is described in detail below , the framework 11 forms a rectangular block shape having a first base member 21 and a second base member 22 , which are generally parallel and separated from each other by transverse base members 23 and 24 . the base members 21 and 22 may extend beyond the ends of transverse base members 23 and 24 , and furthermore , each may be modified not only in terms of length , but may also be broken into smaller members to accommodate particular installations . in a preferred embodiment , base members 21 and 22 extend beyond the transverse base member 23 , but do not extend beyond transverse base member 24 . it will be appreciated by those skilled in the art that many additions , deletions , and modifications to the framework may be made . in the preferred embodiment , vertical junction members 29 , 30 , 31 , and 32 extend upward from base members 21 and 22 at the junction where transverse base members 23 and 24 terminate at base members 21 and 22 . the base members , transverse base members , and vertical junction members may be fixed to each other using a number different methods including , but not limited to , various brackets designs with mechanical fasteners , arc welding , electron beam welding , diffusion bonding , adhesive bonding , soldering or by brazing the members together . in the preferred embodiment , the base members , base transverse members , and vertical junction members are fixed to each other using a plurality of angle brackets 33 . angle bracket 33 may have orifices 34 in each flange of the bracket , such that mechanical fasteners , including , but not limited to , screws , nuts and bolts , etc , may be used to fasten the bracket 33 to the respective ends of the base and transverse members 21 , 22 , 23 , and 24 ( fig1 and 6a ), and connect them to the vertical junction members 29 , 30 , 31 , and 32 . vertical junction members 29 , 30 , 31 , and 32 terminate at top members 25 and 26 , which may be generally parallel to base members 23 and 24 , respectively . transverse top members 27 and 28 are parallel to base members 21 and 22 , and terminate at top members 25 and 26 , where vertical junction members 29 , 30 , 31 , and 32 similarly terminate . the top members 25 and 26 may extend beyond the ends of transverse top members 27 and 28 . in the preferred embodiment , top members 25 and 26 extend beyond both transverse base member 23 , and transverse base member 24 . angle brackets 33 are used to mechanically fasten the top members 25 and 26 and transverse top members 27 , and 28 to vertical junction members 29 , 30 , 31 , and 32 . it should be apparent that additional brackets , or linear or curved members , may be formed and utilized as necessary to accomplish installation of the comfort seat and commode device into the desired apparatus or furnishing . the framework 11 members may utilize many different geometric cross - sectional shapes . the cross - section of the framework members could be a simple cross - sectional shape , such as those which are commonly utilized for extruded metal parts , including , but not limited to , a u - shaped cross - section , a “ t ” shape , an “ h ” shape , an “ i ” shape , an “ l ” shape , a rectangular shape , tubing , etc . it should be noted , however , that the framework members need not be an extruded part , and could be a machining , a forging , or a part formed using any other manufacturing process or some combination of these manufacturing processes . although many different standard shapes are available , a custom designed geometric shape with greater complexity may be used for a particular application . in the preferred embodiment , a basic + shape or cruciform is used , where the cruciform has flanges 35 extending from the ends of each leg of the cruciform at roughly 45 degree angles , as shown in fig6 b . the members may also have grooves 36 running the length of the members , and may additionally have fillets 37 joining the legs of the cruciform to provide greater structural stability and strength . positioned just above the top members 25 and 26 , and transverse top members 27 and 28 is seat 60 . seat 60 is sized so as to provide minimal support while the user is resting upon the particular chair , bed , etc , in which the device is incorporated , but to be sufficiently large enough to create an opening through which the user may urinate or defecate , when the seat has been rotated from a first to a second position to create the opening . the opening would be created by the remaining surface area around the seat 60 , which the user would primarily be resting upon ( not shown ) and which would be supported by top members 25 and 26 , and transverse top members 27 and 28 , and would generally be flush to the edges of seat 60 , as well as generally flush with the top of seat 60 . depending on the materials used for the comfort seat and the surrounding surface area of the apparatus or furnishing into which it is installed , a small gap between the comfort seat and surrounding area may be advantageous or even necessary . seat 60 is supported in the first position , or rest position , by a pair of seat mounting brackets 61 which may be attached to the seat using orifices 69 in the bracket by utilizing mechanical fasteners , such as , but not limited to , bolts , screws , etc . seat mounting brackets 61 have a lug end 62 which is pivotally attached to a pair of devises 64 , where both devises may mount to a top framework member , and in the preferred embodiment , mount to top member 26 . the seat 60 motion may be accomplished by an actuation means driving the seat 60 from the first “ rest ” position , to the second , “ in use ” position . the actuation means could be one of many different actuator types , including linear actuators or rotary actuators , which could be hydraulically actuated , pneumatically driven , driven by an electric motor , and may be also in the form of a servo motor where the shaft is driven to specific angular positions based on the coded signal sent to the servo . depending upon the apparatus or equipment into which the device is incorporated , power requirements may be satisfied by a battery or batteries , or through the use of alternating current . in addition , depending on the actuation means selected , many different mechanical arrangements could be utilized . in the preferred embodiment , rotary actuator 70 has a shaft 71 to which is rigidly attached a first end of drive arm 68 . drive arm 68 may take many different forms , but in the preferred embodiment is an elongated rectangular bar . the second end of drive arm 68 is pivotally attached to a first end of connecting link 67 . connecting link 67 similarly could take many different forms , but in the preferred embodiment is also an elongated rectangular bar . the second end of connecting link 67 is pivotally mounted to the seat 60 . such pivotal mounting may be accomplished through many different configurations of brackets or even use of a clevis , but in the preferred embodiment , mounting brackets 61 are utilized and thus serve a dual purpose . mounting brackets 61 in the preferred embodiment have orifices 63 to retain rod 66 , which spans between the two brackets 61 . connecting link 67 , in the preferred embodiment , is pivotally attached to rod 66 , such that the rotary motion of the shaft 71 of actuator 70 causes rotation of drive link 68 whose motion is transmitted through connecting link 67 to drive seat 60 , via the mounting brackets 61 and rod 66 , to cause the seat 60 to rotate about the lug 62 and clevis 64 pivotal axis . in the preferred embodiment , shown in fig2 , it can be seen that clockwise motion of the shaft 71 of rotary actuator 70 causes the seat 60 to rotate from the initial , at - rest position , to the in - use position . conversely , counterclockwise motion of shaft 71 of rotary actuator 70 causes the seat 60 to rotate from the in - use position to the rest position . the seat actuation means of this invention may be mounted using any number of custom bracket arrangements to suit the particular type of actuator chosen , as well as any variations arising from unique shapes or sizes of the actuator from a particular manufacturer . in the preferred embodiment , rotary actuator 70 is mounted to a support member 75 , which spans between and attaches to top and base framework 11 members . support member 75 may have orifices 76 to accommodate the shaft 71 and mounting pattern of actuator 70 . to work in conjunction with seat 60 and accommodate elimination , a commode is provided in the form of waste bin 40 and cover 41 ( fig1 and 2 ). waste bin 40 may be any shape to accommodate collection of waste , including , but not limited to a rectangular shape , a trapezoidal shape , a conical shape , a cylindrical shape , etc . in the preferred embodiment , a shape that is generally cylindrical was used . waste bin 40 may be mounted to the framework 11 using any number of varying designs , but in the preferred embodiment , waste bin 40 has a lip 39 which permits the waste bin 40 to be inserted into hoop 48 but to be retained by the hoop 48 as the lip 39 reaches the hoop ( fig5 a and 5b ). hoop 48 may have an integral flange for attachment to the framework 11 , but in the preferred embodiment , hoop 48 has orifices 52 which are used to mechanically fasten the hoop to orifices 53 in mounting block 49 . mounting block 49 may also have a plurality of orifices 54 that are used to attach the block 49 to a generally vertical support member 50 . support member 50 is attached to the framework 11 using brackets 51 . support member 50 may simply be a static means to achieve mounting of the waste bin of the commode , where the vertical length of support member 50 can be utilized to provide vertical adjustability of the waste bin . where the support member 50 is utilized as a static means for supporting the waste bin 40 of the commode , it can be seen that a larger sized waste bin may be needed to successfully capture waste eliminated through the opening . however , in the preferred embodiment , support member 50 not only provides static support but also incorporates a linear actuation means so as to be capable of raising and lowering a smaller sized waste bin to be in closer proximity to the opening . the waste bin 40 is not intended to normally be open , which would allow odors to propagate . a cover 41 is provided which normally would be in place over the bin , as seen in fig1 and 2 . the cover 41 is intended to move from a first position to a second position , corresponding to the movement of the seat 60 from its rest position to its in - use position , when the user is seeking to eliminate . the motion of cover 41 may be accomplished through numerous different means , but in the preferred embodiment is accomplished in similar fashion as the seat 60 , by using rotary actuator 43 to which the cover drive arm 42 may be rigidly attached . drive arm 42 may have a flange 57 with orifice 56 , which may be used to mechanically fasten the drive arm 42 to cover 41 . it can be seen that rotary movement of the shaft of rotary actuator 43 will cause rotation of arm 42 , and direct rotation of cover 41 . although the mounting arrangement for the cover actuator 43 may also be accomplished through various different means , actuator 43 is mounted in a similar fashion as seat actuator 70 — through use of actuator support member 80 which also spans between and attaches to top and base framework 11 members . support member 80 may have orifices to accommodate the shaft and mounting pattern of the actuator 43 . in fact , a mirrored set of orifices may be used on the actuator mounting bracket 80 such that one set could be used for mounting the cover actuator 43 , whereby use of an additional support member 80 , in place of the seat actuator support member 75 , would permit mounting the seat actuator 70 , reducing the number of necessary parts . although this is not necessary and the seat and cover actuator member may be individually tailored , it can be seen in fig4 that they could conveniently be the same part . the framework 11 of the invention may also support a cleaning and drying system . the cleaning system may comprise a means for accommodating storage of water as well as soap . the storage may be in the form of a rigid tank or container , or a flexible bladder type storage means . the soap could be in any form , including liquid or powder form , and may even be in solid form with some means for accomplishing mixing appropriate parts of water and soap . delivery of a cleaning solution may be accomplished through tubing and a pump to achieve squirting action , which cleans the user after elimination . alternatively , delivery of the solution may be achieved directly from the storage means without use of tubing of any kind . the drying system may comprise any drying means capable of delivering either warm or cool air to the user . the system may be battery powered or may alternatively , where appropriate , be powered by standard household alternating current . as previously stated , the comfort seat and commode device 10 may be tailored for installation into a range of apparatus , equipment , or furnishings , including , but not limited to , an ordinary arm chair or couch , a bed , a wheel chair , and generally any other means occupied during convalescence or during an extended or permanent period of disability . one possible installation of the comfort seat and commode device 10 is shown in fig7 - 13 , where the device has been incorporated into one particular style of wheelchair . it will be appreciated that other types of wheelchairs or other devices may be used . fig7 shows a top view of the chair with the comfort seat 60 and surrounding seat portion 90 , with a gap 91 between the two . in fig8 , the comfort seat 60 has rotated into the in - use position to create the opening utilized for elimination , revealing the waste bin 40 . fig9 - 12 are side views of the view chair showing the sequential positioning of the seat 60 , waste bin cover 41 , and waste bin 40 . in fig9 , all of those components are in the rest position so the user may normally and comfortably occupy the wheel chair . fig1 shows the seat 60 rotated to the in - use position . fig1 shows the waste bin cover 41 rotated to the in - use position . fig1 shows the waste bin translated to a position beneath the seat 90 of the wheel chair . once the user has successfully completed urination or defecation , the components may be commanded to return to the rest positions for the user to normally occupy the wheelchair . other modifications , substitutions , omissions and changes may be made in the design , size , materials used or proportions , operating conditions , assembly sequence , or arrangement or positioning of elements and members of the preferred embodiment without departing from the spirit of this invention as described in the following claims .
