United States Patent 2,849,726 PORTABLE COMMODE Spencer B. Vay, Palo Alto, Calif. 'Application June 28, 1955, Serial No. 518,594 9 Claims. (Cl. 4-134) This invention relates to a new and improved portable commode.
In general, the object of the invention is to provide a portable commode of unique construction which may be formed from an integral section of foldable sheet material, such as corrugated paper or fiberboard material, and which may be particularly useful where permanent sanitati-on facilities are not available. In this connection it is contemplated that the invention may be advantageously used by hunters and fishermen in areas where it is desired to provide temporary sewage disposal facilities. It is also contemplated that the invention may have important utility in providing a means for sanitary control in military or civil defense evacuation areas or in other emergency situations where more permanent sewage facilities are unavailable or have been destroyed or interrupted.
The particular embodiment of the invention which is illustrated in the drawings and which will be described in more detail hereinafter is made from an integral section of laminated corrugated fiberboard material which is cut and folded to define three primary column-forming panels and three top flaps foldably hingedly joined to the top edges of the panel-forming sections. The section of material is foldably positionable in such manner that the column-forming panels define a hollow vertical openended column substantially triangular in plan. The three top flaps are adapted to be folded across the top open end of the column in superposed relationship. The top flaps are formed with registering cut-outs defining a seat opening. A sewage disposal bag formed of plastic or similar material is vertically positioned in the interior of the column in communication with the seat opening. By utilizing commercially available chemical disinfectants and deodorants the commode facility thus established provides a sanitary and unobjectionable means of sewage disposal over a substantial period of time.
A more specific object of the invention is to provide a portable commode-of the character briefly above mentionedand .which is manufactured from a single section of sheet material utilizingfold lines and die-cuts exclusively and without the necessity of employing stitching, taping, or adhesive to secure any of the joints or parts together.
Another principal object of the invention is to provide a portable commode of the character briefly above mentioned which may be readily folded from its position of use to a relatively flat compact package form for convenience in carrying and shipping, and for convenient repackaging and storing for subsequent use.
Other numerous objects and advantages of the invention will become apparent upon reading the following specification and referring to the accompanying drawings in which similar characters of reference represent corresponding parts in each of the several views.

Referring now more specifically to the drawings, the integral section of sheet material from which the unit is constructed, such as conventional corrugated paper or fibreboard material, is indicated generally at A, and the reference character B indicates generally the disposal bag receptacle.
Referring particularly to Fig. 6, the pattern or blank from which the unit is fabricated comprises three primary column-forming panels 11, 12 and 13, and two secondary panels 14 and 15 respectively. The said primary' and secondary panels 11-15 inclusive are hingedly foldably joined along adjacent side edges by fold lines indicated at 16, 1'7, 18 and 19 respectively. A substantially T-shaped locking tab, indicated generally at 21, and defined by fold lines 22 and 22a and die-cuts 23 is formed as an integral extension of secondary panel 15. A rectangular locking tab 24 is also formed as a further integral extension of tab 21.
Panel 11 is formed with 2 axial slots 26 and 27 and one transverse slot 28 adjacent its upper edge. Panel 12 is formed with one axial slot 29 and one transverse slot 31 adjacent its bottom edge.
Panel 13 is formed with two transverse slots 32 and 33 adjacent its lower and upper extremities respectively. In the embodiment shown, neither of the secondary panels 14 or 15 is slotted, although panel 14 is formed with an upper flap 34 hingedly joined to panel 14 along foldline 36.
Three base flap members indicated at 37, 38 and 39 are hingedly foldably joined along fold-lines 41, 42 and 43 to panels 11, 12 and 13, respectively. Base flap 38 is divided by transverse fold-lines 44 and 45 into two flap sections 38a and 38b and is also provided with a rectangular locking tab 46.
Base flap 39 is provided with an integral extension 47 hingedly joined thereto along double fold-lines 48 and formed with finger-grip apertures 49. As will more fully hereinafter appear, when the unit is folded in its flat compacted package form, apertured extension 48 functions as a convenient carrying handle for the unit.
Three generally triangular-shaped top fiaps 51, 52 and 53 are foldably joined along fold-lines 54, 55 and 56 to panels 11, 12-and 13, respectively. Each of the flaps 51-53 is formed with a die-cut opening, such as indicated at 57, 58 and 59, which said openings when the unit is assembled in a condition for use are in vertical registry with one another to define a seat opening. Preferably the die-cut 57 is made in the form of an interrupted incisure defining a fold-line 61t-which integrally-hingedly joins the seat cover flap 62 to the material defining the body offlapSL,
Opposite sides of -flap 51 are .-forrned with integral tree, E tangular: extensions. or: locking tabs 63-and 64. hinged to flap 51 along fold-lines 65 and 66, respectively. 3
Opposite-sides of'top-flap 52 are :formed with integral tab-lock extensions 67 and 68, respectively, which are not hingedly. joined to the body of flap 52.;by. fOl'Cl-1lDS,": I
but are formed as integral rigid extensions thereof. Said 1" tabs 67. :and 68 are formed with tab-receiving slots 69 I and 70. Flap 52 is also formedwith a fold-line 71 extendingparallehto fold-lines-SSanddefining an area or section indicated at-52a, I
Top flap 53 is formed with integral rigid extension: tabs 72 and 73. Tab 72 isformed with a die-cut slot 74 and tab 73. is provided with a foldable extension tab 75 joined along-fold-line76'to said tab 73.
Fig. 1 discloses how the integral blank. of material above-described can be folded and assembled to a position of use as a commode. Figs. 2 and 5 show further the relative positions of the partswhen the unit is as-.
sembled for ,use; In general, it is observed that the col-' umn-formin'g panels 1113 are folded and assembled relative to one another tordefine a hollow vertical column generally triangular in plan and With secondarypanel 14.115
defining a truncated apex.
The seat of the unit .is defined by the top flaps 51-53 which arefolded along their respective fold-lines 54-'-56 across .the top opening of the column.
The column-forming panels may be securely releasably locked in column formation by T-shaped tab 21 which,.as.shown particularly in Figs. 4 and -5, is projected through slot 26 formed in panel 11 adjacent and parallel to the outer edge ofsaid panel. It is noted that the length ofslot 26 is made. just slightly greater than the distance between fold-lines .22 of folding ears 21a of the tab. along fold-lines 22 to flat overlying. position relative to the body portion of tab 21, the entire tabstructure'can. be forced through the.
slot 26. After insertion of the tab through the slot, the ears 21a. may be unfolded to extend outwardly so as toengage and interlocksagainst. the interior wall surface .-of:='- panel 11. It is appreciated that the panel.21 may be vT-shaped tab 21. By
readily disengaged fromslot 26 simply by again folding the ears 2111 into fiat overlying relationship against the body :of the tab 21 and slidably forcing it outwardly through the slot 26.
As above noted, the structure A above described is adapted to be utilized in conjunction with a suitable sewage bag receptacle indicated generally at Bin the drawings. The bag may be made of any suitable liquidproofsewage resistant material such as plastic, rubber or treated fabric material. The bag B is adapted to be supported vertically within the column opening below and in communication with the seat opening. The particular manner by which the bag may be properly supportedwill shortly be explained.
The manner by which the folded-over top flaps 5153 and the bag B are supported and interlocked in proper position is also indicated in Figs. 1-5 and in Fig. 11 of the drawings. More specifically, in assembling the unit to its position of use'shown in Fig. l, the middle top flap 52 is first foldeddownwardly to extend across :the'top open end of the column. Primary seat support is obtained throughengagement of locking tabs 67 and 68" projected through die-cut slots 28 and 33 formed respectively in panels 11 and 13. With the locking tabs 67 and 68-of top flap 52 engaged in slots 28 and 33, as
above noted, the top flap 53 isfolded over said flap 52 and is'int'erlocked in overlying relationship therewith by means of depending locking tab 75 projected through slot 69 of flap 52. Preferably, the upper regions of the bag B defining its mouth opening are flared laterally outwardly to overlie flap 53.
More specifically, the upper mouth regions of the bag may be flared outwardly to overlie flap 53 and with the .rear edge portions of the bag material projected outwardly through die-cut 28 into hooked engagement with tab 67, and with the opposite side regions of the bag mouth material projectedor tucked in folds 76 and 77 through slots or die-cuts and 74, respectively. The front portion of thefiared bag mouth maybefolded downwardly over the top front edge of the unit. as indicated at 78. With the bag thus positioned, the top flap 51 is folded over across the top open end of the column and in adjacent overlying relationship to the bag material covering flap 53. Interlocking tabs 63 and 64 are folded to such manner. that said: top flaps which define the seat-portion of the unit are able to: withstand and support: a very substantiafvertical compressive load.
It is also observed that. the seat closure flap 62 defined 'by theinterrupted. die-.cut57defines-the top surfaceof m the commodeunit. Fig. 5zillustrates ;how the said flap.
62 can be hingedly foldably swung upwardly and down--.' wardlyto. open andclose the seat opening defined bythe' registering cut-outs 57-59.
When positionedfor use as shown in Fig. lthe; base i;
t flaps 37,:38 and-39am extended laterallyv outwardly :from
the panels to-which they are respectively joined; These;
outwardly extending base flaps provide the unit with a more solid and durable foundation or base support mini mizing likelihood of the paper or fibreboardmaterial teariing or rupturing should it be placed on sharp rocks or: V
gravel orthe like in use. Furthermore, the fingerecarrying. .11
holes 49.plus additional apertures 37a and 35 whichmay g;
- be formed in flaps 37 and 38, respectively, provide pre.-.
formed cut-.outs through which stakes 78 may be. driven into the ground in order to secure theunit more securely in position and prevent its accidental displacement. or"
When it is desired to store, ship, or transport the com- 1". mode unit A, the same may be folded into a'relauvely. a;
flat, compacted package form such as indicated in Figs. .7
and 8, for example.
Said Figs. 7 and 8, together .with Figs. 9 and 10, disclose substantially the relationship of the component parts in their packaged or compacted form.
More specifically, it is observed-that the packagedunit defines, a substantially rectangular parallelepiped struc- I ture in which the front and back sections are defined by panels 13 and 12,.respectively. The end sections of the unit are defined by secondary panel sections 14' and 15;
the top section is defined by section 38a of base flap 38,
and the bottom surface of the package unit is principally defined byportion 52a disposed between fold-lines 55 and 71 of top flap 52. The drawings also show how base fiap' 39 of panel 13 may be folded under top section 3811 whereby the handle section '47 is brought into alignment with and is projected outwardly'through slot 31 of panel 12 for convenient carrying use.
The unit may be releasably locked in its compacted package form by means of tab 46 engaged within slot 32 of panel 13 and by means :of tab 24 engaged through both slot 29 of panel 12 and slot 27 of panelll.
In packaging the unit it is convenient to fold the plasticl-.. bag B into relatively flat form and to package the same within the available space interiorly of the compacted unit A, such as shown in Fig. 9.
Although the foregoing invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be practiced within the spirit of the invention and scope of the appended claims.
