(Cl. 4l14) This invention relates to a portable toilet and particularly to a toilet for use in an automobile, boat, airplane or other vehicle.
It is an object of this invention to provide a portable toilet particularly for use in vehicles, which contains an inexpensive and disposable waste bag that may be removed and disposed of Without objectionable exposure to the waste material.
It is another object of this invention to provide a portable toilet that is almost completely free from accidental discharge of its contents.
It is another object of this invention to provide a portable toilet that may be used without venting, and that has a completely sealed waste compartment that gives off no objectionable odors to the surrounding atmosphere.
It is another object of this invention to provide a portable toilet that is specially adapted to fit beneath a vehicle seat and which is provided with means to restrain movement of the toilet due to vehicle motion but to still render it manually removable.
These objects are accomplished by the portable toilet of this invention which comprises a rigid, protective container and a soft, collapsible, moisture-proof bag or liner for the container. The container comprises an opentopped case which is capable of containing liquids, a cover for the open top and means for restraining the case against inertia, vibration or other vehicular motion. Either the case, the cover or both are provided with a slot intersecting the edge thereof to provide an opening from the interior of the container to the exterior.
The soft collapsible waterproof liner or bag comprises an enlarged bag portion of a size and shape to conform with the shape of the interior of the container. This enlarged bag portion has integral therewith an elongated hose and the hose is positioned, and the slot or slots are positioned so that all are in register and the hose may pass from the interior of the container through the slot or slots when the entire device is assembled.
The details of the various elements as well as the mode of using them will be readily understood with reference to the description of the accompanying drawings in which:
FIG. 1 is a three-part exploded view of the elements of the portable toilet;
PEG. 2 is a bottom view of the case portion of the container assembly;
FIG. 3 is an isometric view of the assembled portable toilet;
FIG. 4 is an elevation partially sectioned view of the hose and adaptor;
FIG. 5 is a top view of a suitable adaptor; and
FIG. 6 is an isometric view of a snap ring useful as hereinafter described.
The portable toilet of this invention consists of a container assembly and a bag assembly as essential elements. The container assembly comprises a case it) and a cover or lid ill. The case 19 is a shallow box which is constructed of metal, plastic, ceramic or other material which is capable of containing a liquid in case of accidental rupture of the waste bag. The case 10 is provided with magnets 12 embedded in the bottom or other portion thereof to restrain it against motion due to vehicular motion. The case shown in this embodiment is also provided with a slot 13 and a carrying handle 14. The lid 11 is constructed to fit over the case and may be provided with a latch or lock means to hold it firmly on the case. The lid as herein shown contains a slot 15 and a spring clip 16 positioned on the top surface of the lid and in the vicinity of the slot 15. The slot 15 in the lid and the slot 13 in the case are positioned so that when the lid is installed on the case the slots will be in register forming an opening or passageway into the assembled container.
The bag or liner assembly 17 comprises an enlarged enclosed water proof bag portion 18 which is herein illustrated in inflated form but which, in a preferred embodiment, is collapsed and evacuated of air. The bag assembly also includes an elongated hose 26 which is sealed into bag 18 at one end thereof and terminates in a beading 21 at the other end thereof. The hose 26 is sealed into bag 18 to position it in alignment with the opening formed by slots 13 and 15.
When in use the case and lid form an enclosed hard container of small vertical dimension surrounding the waterproof bag and suitable for installation, for example, beneath the seat of a vehicle. As shown in FIG. 3, when not in use the hose 20 extends out of the assembled container and preferably extends downward from the opening and through a reverse bend upwardly Where it is again folded back on itself and held with a clip 16. A small quantity of water 22 placed in the U-bend forms a complete liquid seal and since the collapsed bag is capable of expanding as it is filled, there is no need for venting this device during use. As a result the portable toilet of this invention is completely sealed from the surrounding atmosphere and therefore is sanitary and odorless avoiding the objectionable features of portable toilets heretofore employed. In addition, it is placed out of the way and firmly held in place thereby obviating accidental discharge of its contents.
To improve the utility of the device of this invention, an adaptor 23 made of metal, plastic or other material that is rigid enough to maintain its shape is employed. Preferably the adaptor will have a long narrow funnel portion 24 and a circular conduit portion 25. The adaptor may be employed by sliding the beaded end portion of hose 26) over conduit 25 and holding it there by such means as a split circular spring 26 as best shown in FIG. 6. The split circular spring preferably constitutes a ring of metal or plastic capable of resiliently closing after being spread and having a slightly smaller normal diameter than the diameter of conduit 25. When installed asillustrated in FIG. 4, the spring will hold hose 29 onto conduit 25 both by the spring pressure against conduit 25 and by mechanically engaging the bead 21.
By maintaining the dimensions, that is the diameter of hose 2t and conduit 25, fairly small, for example less than 1% inches, the device of this invention may be flushed after use with a small quantity of water which will not only Wash the interior of conduit 2% and hose 2%, but which will, in addition, provide the sealing liquid 22 in the reverse bend of the hose. It is highly desirable to construct conduit 25 at least 4 inches or longer so that the interior of the folded-back portion of hose 20 under spring clip 16 is dry.
To use the toilet of this invention, it is initially installed beneath a vehicle seat, adjacent a wall or in some other place for which it may or may not be specially shaped. Before its first use there is no need to seal the interior. When it is desired to use this device, the hose Ztl is fitted with the adaptor and extended, preferably with an unobstructed path to the interior of bag 18. After use the hose and adaptor may be flushed with a small quantity of water, if water is available, and a liquid seal placed in a reverse bend of the hose. The liquid seal is a perfect seal and represents a preferred use of this invention; how- I ever, by sharply folding and holding hose 2%, a satisfactory mechanical seal may be provided as, for example, the doubly folded hose under clip 16 as pictured in FIG. 3.
The toilet may be used and re-sealed any number of times as described and when its capacity is reached, or upon termination of the use of the vehicle, the device may be emptied. Emptying is accomplished first by removing the container from its place in the vehicle and, remote from the vehicle, removing the lid. It may be convenient at this time to seal the tube with a clothes pin, paper clip, spring clip or other clamping means. The collapsible bag, which may still be in the open-topped case, may then be taken to a point of disposal. During the entire emptying operation, there is never exposure to the contents of the bag.
There may be many variations in the shape, size, manner of fastening and relationship of the parts of the toilet within the scope of this invention. By Way of example, the case or lid may be firmly locked together and may be attached to the vehicle with clips, hooks, nesting in recesses, bolts, etc. The bag may be of rubber, rubberized fabric, plastic sheet material or other material that is water-proof, scalable and inexpensive enough to be disposable.
This invention provides a portable toilet that is compact and concealable, that is unaffected by vehicular motion and accidental spilling and one that may be installed, used, carried and finally disposed of Without exposing the user to the unsanitary and unpleasant Waste material therein.
