3 Claims. (Cl. 155-31) This invention relates to an invalids commode. More particularly, this invention relates to a wheel-chair or the like construction wherein a portion of the seat is removable from beneath and either in back or in front of the chair so that a receptacle may be positioned under the resulting opening in the seat in order to accommodate the bodily functions of the patient in the chair without requiring the patient to be moved with respect to the chair.
There are numerous diseases such as muliple sclerosis, and various other forms of muscular atrophy and paralysis which render it extremely undesirable or often impossible to move a wheel-chair patient with respect to the wheel-chair in order to permit the use of an ordinary bedpan or other receptacle designed to accommodate the bodily functions of the patient. The length of time during which patients having such diseases can safely and comfortably remain in a wheel-chair has in the past been adversely affected by the necessity of moving the patient in order to make provision to accommodate his bodily functions.
It is therefore an object of this invention to provide a wheel-chair or similar means for supporting the patient wherein a portion of the seat thereof is removable from an opening therein in order that a receptacle may be positioned beneath the opening to accommodate the bodily functions of the patient without the necessity of moving the patient in the chair.
It is a more general object of this invention to provide a wheel-chair having a commode as a builtin feature of the structure thereof.
It is a further object of this invention to provide such a wheel-chair wherein the removable portion of the seat is normally firmly supported in position to form a continuous top seat surface with the rest of the seat but may be removed from beneath or in back of the seat without disturbing the patient in the chair.
Other objects, features and advantages of the present invention will be more fully apparent from the following detailed description of a preferred exemplary embodiment thereof when taken in connection with the accompanying drawings in which like reference characters are used to refer to like parts throughout and wherein:
Figure 1 is a perspective view looking upwardly from the back of a wheel-chair constructed in accordance with the present invention.
Figure 2 is a plan View of the top of the seat of the chair of the present invention.
Figure 3 is a sectional view taken on the line III-HI of Figure 2.
Figure 4 is a plan view with parts in elevation showv 2,942,648 Patented June 28, 1960 Figure 1 thereof, there is shown a wheel-chair 10 incorporating an invalids commode in accordance with the present invention. The general manner of construction of the wheel-chair may be of any convenient or wellknown type and as illustrated comprises spoked wheels 11 and 12 which are respectively attached by stub axles 13 and 14 to the rear vertical frame members 15 and 16 (a portion of the member 16 being broken away for clarity of illustration). Frame members 15 and 16 are in turn attached to generally horizontal seat supporting frame members 17 and 18 which extend forwardly from the rear vertical support members 15 and 16 and continue downwardly near the front of the chair to support a foot rest 19. Lower horizontal frame members 21 and 22 are connected between the lower portions of the rear frame members 15 and 16 and the forward downward extension of the frame members 17 and 18 in order to afiord structural rigidity and to provide a support for the front wheels 23 and 24 which are mounted by means of yokes 25 and 26 to the frame members 21 and 22. Frame members 27 and 28 are preferably welded to the frame members 21, 17 and 22, 18 respectively in order to provide further rigidity and may continue upwardly and rearwardly to be joined to the vertical rear frame members 15 and 16 thereby affording arm rest members 29 and 30. Any suitable back support member 31 is attached to the rear vertical frame members 15 and 16 as shown and these frame members may terminate in handles 32 and 33 by which the chair many be conveniently wheeled.
Considering now in particular Figures 1, 2, and 3, it will be noted that a first seat member 35 is attached to the frame of the chair and supported thereby. Member 35 may, for example, be attached to or removably mounted on horizontal frame work members 17 and 18 in any convenient manner and may further be held more firmly in position by abutment with upright frame members 27 and 28 as well as to members 15 and 16. The outer edge or perimeter of the first seat member 35 is shaped to be received by the above-noted framework members and to thereby provide a seat for a human patient in said chair.
To accommodate sidewise folding of the chair, the rigid seat member 35 can be removed from the frame or can have one side hingedto a frame 17 or 18. The first seat member 35 is further provided with a centrally positioned generally elliptically shaped opening in which a sec ond seat member 36 of generally the same shape as the opening is adapted to be removably secured so that the first and second seat members will mate to form a continuous top seat surface. To this end, padding 35a and a covering 35b may be provided on the first seat member and similar padding 36a and covering material 36b may be provided on the second seat member. A third seat member or extension 37 may also be attached to the back or rear edge of the first seat member 35 in order to prevent the clothing of the patient from slipping down over the rear edge of seat 35. Extension member 37 may similarly be provided with padding 37a and covering material 37b. The covering material may conveniently extend across the entire top surface of each of the seat members and may conveniently be folded down around the edges thereof and tacked or otherwise attached to the bottom surfaces of the seat members as seen most clearly in Figure 4. It will be noted from Figure 2 that when the seat members 35 and 36 are in assembled relationship a substantially continues top seat surface is afforded,
to the undersurface thereof a supporting member 40 all. i If f preferably inltheiformlofia v-shaped bar. i v bar .40 has legs 40a and 40b which are rigidly attached to the underside of seat member 36 by bolts 41, 42, 43 and 44. If desired; spacers such as shown at 43d and 44mm Figure 3;maysbeiprovided itotholduthe Vi bar rigidlygat. apredetermined ldistance :from th'e seat member 3&1 Although other supporting i means; may be I used, ith'e f advantage of thesvibari arrangement lies in the fact that it affords supporttatnthe ltwo Sides of Q the central seat "member- 36 thereby: lending grenter stabilityto this seat member when itis in pcsitionrin 'the chair p V The -armi49aof thev bar 40 rests' in -a flange member 45ewhereas the arm .4012 rests,- inra flange member 46. Flange imember v45 is: secured throughthe' underside ofthefirSt-seaL member 35 as by screws or lag bolts 47'and flange:member:46 'is similarly attached by screws or -la'g bolts '48. It wi-ll'be noted that the flange members are' prov-ided with upwardly sloping-bottom surfaces 45d and 46a.:and 'inwardlysloping outer surfaces 45b and 46b 'If it is desired 'toprovide-a"cornniodexwhreimthe patient himself can operate the-device, the relative positions of flanges 45 and 46-"and;rlatch;.-41icouldgof course, ho reversed so that the V -bar supporting member 46 projects toward the front of-the'chair." In such a construction the V-bar 40 should preferably extend up to but not beyond the front of seat member 35. Of course,
' also extend to the front'of seat-member -35.
It will further be apparent that'although'theinvalids serving to guide the arms-49a and 40b into holes or-re- 0 commode has been-described in' connection withia wheelpositi0n=shown in Figures 1 and 4 inorder tohold the V=bar assembly-and seat member fifi-in-positionr Latch arm-:47 is rotatablyrnounted on a bolt or other support- 7 ing means 48 which secures the latchto the underside of thefirst seat member 35. When it is desired toremove the second or central seat portion 36- from the chair,
the-=latch member 47 is rotated permitting the V bar to be; lowered and slid down the slopingsurfaces of the 'flange members 45 and '46 so that the seat portion 36 may'be-withdrawn'from beneath and behind the chair 16;;
