United States Patent 3,066,311 PORTABLE ROUND TOILET BUILDING Homer R. Tharp, 610 E. Josephine St., San Antonio 2, Tex. Filed Oct. 17, 1961, Ser. No. 145,691 Claims. (ill. 4--3) This invention relates to a portable round toilet building which is completely self-contained and which may be moved from place to place as necessary to provide toilet facilities in out-of-the-way situations, such, for example, as the site of construction projects, public affairs meetings held out-of-doors, and the like.
A primary object of the invention is the provision of a round portable toilet building of this character which will be completely self-contained and which will conform to the several sanitation code requirements of the variable States.
An additional object of the invention is to provide a lightweight portable toilet building of circular construction and formed on a base in such manner as to render it highly resistant to overturning by wind, crowd pressure, or similar forces.
A further object of the invention is the provision of a device of this character which is made of lightweight material, such as plastic, fiber glass, or the like, which requires no connection to any outside source of water or sewage.
Still another object of the invention is the provision of a device of this character having a self-closing door.
Still another object of the invention is the provision of such a toilet building which is of a weight and size to facilitate its ready transportation from site to site as may be necessary or desirable.
A further object of the invention is the provision of a device of this character which is sturdy and durable in construction, reliable and efiicient in operation, and also in accord with all of the several sanitary codes, and which is relatively inexpensive to manufacture.
Still other objects will in part be obvious and in part be pointed out as the description of the invention proceeds and shown in the accompanying drawing wherein:
FIGURE 1 is a perspective view of one form of portable building constructed in accordance with the instant invention.
FIGURE 2 is an enlarged sectional view taken substantially along the line 22 of FIG. 1 as viewed in the direction indicated by the arrows.
FIGURE 3 is an enlarged sectional view, partially broken away, disclosing in detail the apparatus for rendering the door self-closing; and
FIGURE 4 is an enlarged sectional view taken substantially along the line 4-4 of FIG. 2 as viewed in the direction indicated by the arrows.
Similar reference characters refer to similar parts throughout the several views of the drawing.
Referring now to the drawings in detail, the device of the instant invention comprises a base or platform having a generally arcuate forward end 11 and supported by skids 12 which extend substantially the full length of the platform. The forward ends of the skids preferably terminate in tapered portions 13 to facilitate the sliding of the device along the ground. Base 10 is preferably constructed of a material such as fiber glass or molded plastic or the like and a ring towing connection 14 is permanently molded into the center of the arcuate front portion 11.
A generally cylindrical upright building structure or body 18 is fixedly secured to the base in rigid relation in any desired conventional manner, and is provided with a vertical access opening extending the entire height thereof, the opening being generally indicated at 19. An arboth the housing or building 18 in the door being constructed of fiber glass or similar lightweight rigid material.
The door is mounted at its upper extremity in a channel 22 and is provided with rollers 2211 which move between the flanges 23 and 23a of the channel 22.
A series of spacing elements 24 are positioned circumferentially about the top of housing or building 18 and serve to support a fiat conical roof 25 in spaced relation to the top wall of the building in order to provide vent openings for ventilation purposes.
The lower portion of the platform is provided with an arcuate track forming channel 28 aligned with and corresponding to the upper channel 22, and rollers 29 are carried by the lower portion of the door 241) operating in the channel 28. Brackets 30 depending from the lower portion of the door serve to support the rollers 29.
The opposed edges of the opening 19 are provided with facing members 32 and 33, respectively, one of the facing members, 32, having at least one recess therein in which is positioned a vertical rod 35 which carries a spring loaded rotatable reel 36. A line 37 is secured by one end to and extends about reel 36 and has its free end extending through an aperture 38 in housing 13 and secured to the edge of the door by any suitable fastening member 39. A torque spring 40 provides the spring bias for the reel, and has one of its ends secured in the base of the opening 34 as indicated at 34a, and the other of its ends secured to reel 36, the arrangement being such as constantly to bias the string or cord wound about the reel 36 in a direction to close the door 19. As indicated, the cord or line 37 is secured adjacent the top of the door so as not to interfere with ingress and egress to and from the building.
The building contains the usual facilities including a toilet bowl 43 having a seat 44 and a top 45 and a urinal 46 which is supported by a vent pipe 47 which extends upwardly through the top 25 so that any fumes normally occurring are vented to the atmosphere. Both the bowl 43 and urinal 46 contain any suitable liquid or semiliquid chemical solution of well-known characteristics to dissolve and render odorless human excretion without the necessity of connection to a sewage system, or the necessity of running water in the building. Obviously, upon occasions where running water and connection to a sewage system is readily available, appropriate connections may be made both to the bowl 43 and the urinal 46 or the lower end of the vent pipe 47 for connection as may be desirable.
A rack 50 is provided on the inner wall of the housing 18 and has mounted therein one or more rolls of toilet tissue 51 as, for example, on a spindle 52.
A slot 53 extends transversely across the platform 10 to facilitate the cleaning of the interior of the build ing 18. q
The safety factor inherent in a round structure of this type provides extra insurance against damage in strong winds created by man or by nature. Hurricanes, strong gusts, prop wash, and exhaust from jet aircraft have less of an effect on a streamlined structure of the present type than on the standard square type.
The sanitary features inherent in fiber glas should also be noted. Fiber glass is practically non porous, it is slick, and cleans extremely well. Water and cleaning materials apply with remarkable ease and flush oif equally as well. Solids do not cling very readily to its slick surface.
From the foregoing it will now be seen that there is herein provided an improved portable round toilet building which accomplishes all the objects of this invention,
and others, including many advantages of great practical utility and commercial importance.
As many embodiments may be made in this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative, and not in a limiting sense.
